        2. REPRESENTATIONS AND WARRANTIES. The Borrower represents and warrants
to the Lenders and the Administrative Agent as follows:

               (a) AUTHORIZATION, VALIDITY AND BINDING EFFECT. This Amendment
        has been duly authorized by all necessary corporate action on the part
        of the Borrower, has been duly executed and delivered by a duly
        authorized officer or officers of the Borrower, and constitutes the
        valid and binding agreement of the Borrower, enforceable against the
        Borrower in accordance with its terms.

               (b) REPRESENTATIONS AND WARRANTIES TRUE AND CORRECT. The
        representations and warranties of the Borrower contained in the Credit
        Agreement, as amended hereby, are true and correct on and as of the date
        hereof as though made on and as of the date hereof, except to the extent
        that such representations and warranties expressly relate to a specified
        date, in which case such representations and warranties are hereby
        reaffirmed as true and correct when made.

               (c) NO EVENT OF DEFAULT, ETC. No condition or event has occurred
        or exists which constitutes or which, after notice or lapse of time or
        both, would constitute an Event of Default.

               (d) COMPLIANCE. The Borrower is in full compliance with all
        covenants and agreements contained in the Credit Agreement, as amended
        hereby.

        the Lenders and the Administrative Agent complete and correct copies of
        the unaudited condensed consolidated balance sheet of the Borrower and
        its consolidated subsidiaries as of September 30, 1998, and the related
        unaudited condensed consolidated statements of income and of cash flows
        of the Borrower and its consolidated subsidiaries for the fiscal period
        then ended, as contained in the Form 10-Q Quarterly Report of the
        Borrower filed with the SEC. All such financial statements have been
        prepared in accordance with GAAP, consistently applied (except as stated
        therein), and fairly present the financial position of the Borrower and
        its consolidated subsidiaries as of the date indicated and the
        consolidated results of their operations and cash flows for the period
        indicated, subject to normal audit adjustments, none of which will
        involve a Material Adverse Effect.

        outstanding General Revolving Loans shall have been prepaid in full out
        of the proceeds of one or more Borrowings from all of the Lenders party
        to the Credit Agreement, as amended hereby (with the Administrative
        Agent, the Borrower and the Lenders party to the Credit Agreement before
        the addition of The Huntington National Bank making arrangements, to be
        coordinated by the Administrative Agent, for the netting of amounts due
        to or from such parties).

 The Administrative Agent shall notify the Borrower and each Lender in writing
of the effectiveness hereof.

hereby amended so that any reference therein to the Credit Agreement shall mean

limitation the costs and fees of the Administrative Agent's special legal
counsel, regardless of whether this Amendment becomes effective in accordance
with the terms hereof, and all costs and expenses incurred by the Administrative
Agent or any Lender in connection with the enforcement or preservation of any
rights under the Credit Agreement, as amended hereby.

        5.5. SEVERABILITY. Any term or provision of this Amendment held by a
court of competent jurisdiction to be invalid or unenforceable shall not impair

        PRELIMINARY STATEMENTS:

        (1) The Borrower, the Lenders named therein, and the Administrative
Agent entered into the Amended and Restated Credit Agreement, dated as of
December 1, 1998, as amended by Amendment No. 1 thereto, dated as of March 31,
1999, Amendment No. 2 thereto, dated as of April 19, 1999, Amendment No. 3
thereto, dated as of August 13, 1999, and Amendment No. 4 thereto, dated as of
August 31, 1999 (as so amended, the "CREDIT AGREEMENT"; with the terms defined
therein, or the definitions of which are incorporated therein, being used herein
as so defined).

        (2) The parties hereto desire to amend certain of the provisions of the
Credit Agreement, all as more fully set forth below.

        NOW, THEREFORE, the parties hereby agree as follows:

        1. AMENDMENTS, ETC. 1.1. CONSOLIDATED CAPITAL EXPENDITURES. Effective on
and as of the Effective Date of this Amendment provided for in section 3 hereof,
but with retroactive effect to January 1, 1999, section 9.9 of the Credit
Agreement is amended to read in its entirety as follows:

               9.9. CAPITAL EXPENDITURES. The Borrower will not, and will not
        permit any of its Subsidiaries to, make or incur Consolidated Capital
        Expenditures during any fiscal year (i) in excess of $9,000,000, in the
        case of the fiscal year ended December 31, 1999, (ii) in excess of
        $7,000,000, in the case of the fiscal year ended December 31, 2000, or
        (iii) in excess of $5,000,000, in the case of any subsequent fiscal
        year. In the event actual Consolidated Capital Expenditures for any
        fiscal year are less than such amount, the excess amount may not be
        carried over to any subsequent period.

        1.2. CONSENT TO ACQUISITION. As contemplated by the definition of the
term "Permitted Acquisition" contained in section 1.1 of the Credit Agreement,
the Lenders hereby consent to the

<PAGE>

Acquisition by the Borrower of Video Images, Inc., on the terms generally
described in the descriptive materials previously furnished to the Lenders by
the Borrower.

        2. REPRESENTATIONS AND WARRANTIES. The Borrower represents and warrants
to the Lenders and the Administrative Agent as follows:

               (a) AUTHORIZATION, VALIDITY AND BINDING EFFECT. This Amendment
        has been duly authorized by all necessary corporate action on the part
        of the Borrower, has been duly executed and delivered by a duly
        authorized officer or officers of the Borrower, and constitutes the
        valid and binding agreement of the Borrower, enforceable against the
        Borrower in accordance with its terms.

               (b) REPRESENTATIONS AND WARRANTIES TRUE AND CORRECT. The
        representations and warranties of the Borrower contained in the Credit
        Agreement, as amended hereby, are true and correct on and as of the date
        hereof as though made on and as of the date hereof, except to the extent
        that such representations and warranties expressly relate to a specified
        date, in which case such representations and warranties are hereby
        reaffirmed as true and correct when made.

               (c) NO EVENT OF DEFAULT, ETC. No condition or event has occurred
        or exists which constitutes or which, after notice or lapse of time or
        both, would constitute an Event of Default.

               (d) COMPLIANCE. The Borrower is in full compliance with all
        covenants and agreements contained in the Credit Agreement, as amended
        hereby.

               (e) RECENT FINANCIAL STATEMENTS. The Borrower has furnished to
        the Lenders and the Administrative Agent complete and correct copies of
        the unaudited condensed consolidated balance sheet of the Borrower and
        its consolidated subsidiaries as of September 30, 1999, and the related
        unaudited condensed consolidated statements of income and of cash flows
        of the Borrower and its consolidated subsidiaries for the fiscal period
        then ended, as contained in the Form 10-Q Quarterly Report of the
        Borrower filed with the SEC. All such financial statements have been
        prepared in accordance with GAAP, consistently applied (except as stated
        therein), and fairly present the financial position of the Borrower and
        its consolidated subsidiaries as of the date indicated and the
        consolidated results of their operations and cash flows for the period
        indicated, subject to normal audit adjustments, none of which will
        involve a Material Adverse Effect.

        3. EFFECTIVENESS. This Amendment shall become effective on a date (the
"EFFECTIVE DATE"), on or before December 31, 1999, if the following conditions
are satisfied on or before the Effective Date:

        the Administrative Agent, and counterparts hereof as so executed shall
        have been delivered to the Administrative Agent;

               (b) the Acknowledgment and Consent appended hereto shall have
        been executed by the Credit Parties named therein, and counterparts
        hereof as so executed shall have been delivered to the Administrative
        Agent;
                                       2
<PAGE>

               (c) the Administrative Agent shall have been notified by the
        RequiredLenders that such Lenders have executed this Amendment (which

        to the Lenders.

shall notify the Borrower and each Lender in writing of the effectiveness
hereof.

shall modify and supersede all inconsistent terms and provisions set forth in
the Credit Agreement, and except as expressly modified and superseded by this
Amendment, the terms and provisions of the Credit Agreement are ratified and
confirmed and shall continue in full force and effect.

        5. MISCELLANEOUS. 5.1. SUCCESSORS AND ASSIGNS. This Amendment shall be
binding upon and inure to the benefit of the Borrower, each Lender and the
Administrative Agent and their respective permitted successors and assigns.

        5.2. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties made in this Amendment shall survive the execution and delivery of
this Amendment, and no investigation by the Administrative Agent or any Lender
or any subsequent Loan or issuance of a Letter of Credit shall affect the
representations and warranties or the right of the Administrative Agent or any
Lender to rely upon them.

        5.3. REFERENCE TO CREDIT AGREEMENT. The Credit Agreement and any and all
other agreements, instruments or documentation now or hereafter executed and
delivered pursuant to the terms of the Credit Agreement as amended hereby, are
hereby amended so that any reference therein to the Credit Agreement shall mean
a reference to the Credit Agreement as amended hereby.

        5.4. EXPENSES. As provided in the Credit Agreement, but without limiting
any terms or provisions thereof, the Borrower agrees to pay on demand all costs
and expenses incurred by the Administrative Agent in connection with the
preparation, negotiation, and execution of this Amendment, including without
limitation the costs and fees of the Administrative Agent's special legal
counsel, regardless of whether this Amendment becomes effective in accordance
with the terms hereof, and all costs and expenses incurred by the Administrative
Agent or any Lender in connection with the enforcement or preservation of any
rights under the Credit Agreement, as amended hereby.

        5.5. SEVERABILITY. Any term or provision of this Amendment held by a
court of competent jurisdiction to be invalid or unenforceable shall not impair
or invalidate the remainder of this Amendment and the effect thereof shall be
confined to the term or provision so held to be invalid or unenforceable.

        5.6. APPLICABLE LAW. This Amendment shall be governed by and construed
in accordance with the laws of the State of Ohio.

        5.7. HEADINGS. The headings, captions and arrangements used in this

deemed to be an original, but all of which when taken together shall constitute
