        THIS AMENDMENT NO. 1 TO AMENDED AND RESTATED CREDIT AGREEMENT,
dated as of March 31, 1999 ("THIS AMENDMENT"), among:

                   (i) MIAMI COMPUTER SUPPLY CORPORATION, an Ohio corporation
         (herein, together with its successors and assigns, the "BORROWER");

                  (ii) the financial institutions listed on the signature pages
         hereof (the "LENDERS");

                 (iii) NATIONAL CITY BANK, a national banking association, as a
         Lender and as Documentation Agent; and

                 (iii) PNC BANK, NATIONAL ASSOCIATION, a national banking
        association, as a Lender, the Swing Line Lender, a Letter of Credit
        Issuer and as Administrative Agent (the "ADMINISTRATIVE AGENT") for the
        Lenders under the Credit Agreement:

        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 (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 make certain changes in the terms and
provisions of the Credit Agreement, all as more fully set forth below.

        NOW, THEREFORE, the parties hereby agree as follows:

         1. AMENDMENT. Effective as of December 31, 1998, 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 in excess of $6,675,000, in the case
        of the fiscal year ended December 31, 1998, or 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.

         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

<PAGE>

        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.

        3. EFFECTIVENESS. This Amendment shall become effective on and as of a
date, on or before April 7, 1998 if the following conditions are satisfied:

               (a) this Amendment shall have been executed by the Borrower and
        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; and

               (c) the Administrative Agent shall have been notified by the
        Required Lenders that such Lenders have executed this Amendment (which
        notification may be by facsimile or other written confirmation of such
        execution).

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

        4. RATIFICATIONS. The terms and provisions set forth in this Amendment
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

Lender to rely upon them.

other agreements, instruments or documentation now or hereafter executed and
delivered pursuant to the terms of the Credit Agreement as amended hereby, are

Agent or any Lender in connection with the enforcement or preservation of any

in accordance with the laws of the State of Ohio.

matters expressly set forth herein. This Amendment and all other instruments,
agreements and documentation executed and delivered in connection with this
Amendment embody the final, entire agreement among the parties hereto with
