                                       TO
                      AMENDED AND RESTATED CREDIT AGREEMENT

        THIS AMENDMENT NO. 6 TO AMENDED AND RESTATED CREDIT AGREEMENT,
dated as of January 10, 2000 ("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

               (iv) 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, 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, Amendment No. 4 thereto, dated as of
August 31, 1999, and Amendment No. 5 thereto, dated as of December 20, 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. INCREASE IN TOTAL GENERAL REVOLVING COMMITMENT;
ADDITIONAL LENDER. Effective on the Effective Date of this Amendment provided
for in section 3 hereof:

               (a) the Total General Revolving Commitment is increased from
        $150,000,000 to $160,000,000;

               (b) the General Revolving Commitments of all of the existing
        Lenders (herein, together with their successors and assigns, the
        "EXISTING LENDERS") remain at the existing levels, namely $25,000,000
        each; and

               (c) The Provident Bank (herein, together with its successors and
        assigns, the "NEW LENDER") joins in the Agreement with a General
        Revolving Commitment of $10,000,000, and

<PAGE>

        Annex I to the Credit Agreement is amended to reflect the addition of
        The Provident Bank as a Lender with a General Revolving Commitment of
        $10,000,000.

        1.2. ACTIONS NECESSARY FOR PRO RATA PARTICIPATION BY NEW LENDER IN
OUTSTANDING LOANS, ETC. Notwithstanding anything to the contrary contained in
the Credit Agreement:

               (a) during the period ending March 31, 2000 (or such earlier date
        as the Administrative Agent may specify on notice to the other parties),
        the parties will take such actions as the Administrative Agent may
        specify so that by the end of such period the New Lender's percentage of
        each Borrowing of General Revolving Loans which is then outstanding is
        identical to its General Revolving Facility Percentage;

               (b) in furtherance of and without limitation of the foregoing,
        during such period the Administrative Agent may require that the New
        Lender fund new General Revolving Loans disproportionately to, or to the
        exclusion of, some or all of the other Lenders, until the New Lender's
        percentage of each Borrowing of General Revolving Loans which is then
        outstanding is identical to its General Revolving Facility Percentage;

               (c) during the period referred to above,

                             (1) all selections by the Borrower of the duration
                      of an Interest Period shall be subject to the approval of
                      the Administrative Agent,

                             (2) the Administrative Agent may permit a new
                      Interest Period to be of a specified duration shorter than
                      one month (but priced as if it were a one month period),

                             (3) to the extent reasonably feasible, the
                      Administrative Agent shall endeavor to coordinate new
                      Borrowings such that all Eurodollar Loans have Interest
                      Periods which end at the same time or reasonably
                      contemporaneously, and

                             (4) the Administrative Agent may restrict the
                      availability of Eurodollar Loans consistent with the
                      foregoing;

               (d) if on March 31, 2000 (or an earlier date selected by the
        Administrative Agent and notified to the other parties), the percentage
        of any Lender of any Borrowing of General Revolving Loans is not the
        same as such Lender's General Revolving Facility Percentage, THEN the
        Borrower will on such Business Day as may be selected by the
        Administrative Agent and notified to all of the other parties on not
        less than two Business Day's prior written notice, prepay such
        Borrowings of General Revolving Loans as the Administrative Agent may
        specify, together with accrued interest and any breakage compensation
        payable under section 2.10 of the Credit Agreement, SUBJECT to the right
        of the Borrower to re-borrow some or all of such General Revolving Loans
        on a pro rata basis from all Lenders;

               (e) during the period referred to above and in order to eliminate
        any further complications which might result therefrom, The Provident
        Bank will not assign or transfer any Commitment under the Credit
        Agreement without the prior approval of the Administrative Agent; and

                                        2
<PAGE>

               (f) notwithstanding the above, no Lender shall be obligated to
        make any General Revolving Loan which would result in such Lender's
        aggregate General Revolving Loans, plus its General Revolving Facility
        Percentage of the Letter of Credit Outstandings, exceeding its then
        General Revolving Commitment.

        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 January 20, 2000, if the following conditions
are satisfied on or before the Effective Date:

               (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;

                                        3
<PAGE>

               (c) the Administrative Agent shall have been notified by the New
        Lender and all of the Existing Lenders that such Lenders have executed
        this Amendment (which notification may be by facsimile or other written
        confirmation of such execution);

               (d) the Borrower shall have duly executed and delivered to the
        Administrative Agent, for the account of the New Lender, a General
        Revolving Note made payable to the order of the New Lender and
        conforming to the requirements of the Credit Agreement;

               (e) the Borrower shall have delivered to the Administrative Agent
        a certificate of its Secretary or an Assistant Secretary, dated as of a
        recent date, certifying the due adoption by the Doard of Directors of a
        resolution or resolutions approving the increase in the Total General
        Revolving Commitment under the Credit Agreement to $160,000,000, and
        certifying that such resolution(s) remains in full force and effect, and
        such certificate and resolution(s) shall be satisfactory in form and
        substance to the Administrative Agent; and

               (f) either (x) the Borrower shall have paid directly to the New
        Lender such nonrefundable closing fees as have been previously agreed to
        between the Borrower and the New Lender, or (y) the Borrower shall have
        paid such fees to the Administrative Agent, for the account of the New
        Lender (the Administrative Agent hereby agreeing to promptly re-transmit
        such fees to the New Lender).

Subject to satisfaction of the foregoing conditions, 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
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

<PAGE>

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
Amendment are for convenience only and shall not affect the interpretation of

agreements and documentation executed and delivered in connection with this
Amendment embody the final, entire agreement among the parties hereto with

oral, relating to the matters covered by this Amendment, and may not be

        Borrower will not at any time permit the ratio of (i) the amount of
        Consolidated Total Debt at such time to (ii) Consolidated EBITDA for the
        Testing Period most recently ended, to exceed (x) 4.30 to 1.00 in the
        case of any Testing Period ended on or prior to June 29, 2000, (y) 4.00
