<PAGE>   2

                                      -2-


            "Section 3.1. TOTAL CREDIT FACILITY. In consideration of Baldwin's
      payment and performance of its Obligations and subject to the terms and
      conditions contained in this Credit Agreement, the Lenders agree to
      provide, and Baldwin agrees to accept, an aggregate credit facility of up
      to (i) Twenty Million and 00/100 Dollars ($20,000,000.00) on or before
      March 29, 2000 and (ii) Seventeen Million and 00/100 Dollars
      ($17,000,000.00) after March 29, 2000 (the "TOTAL CREDIT"), subject to the
      terms and conditions hereof (the "CREDIT FACILITY"). No Loans need be made
      by the Lenders if Baldwin is in Default or if there exists any Unmatured
      Default (and such Default or Unmatured Default has not been waived by
      Agent and Lenders). This is an agreement regarding the extension of
      credit, and not the provision of goods or services."

      4.    ELIGIBLE ACCOUNTS AND ELIGIBLE INVENTORY. Effective immediately upon
consummation of the Sale (as defined in Section ), Section 3.2(a)(i) and Section
3.2(a)(ii) of the Credit Agreement shall be amended in their entirety to read as
follows:

                  "(i) ELIGIBLE ACCOUNTS. On receipt of each Borrowing Base
            Certificate, in the form of Exhibit C, together with such
            supporting information as Agent may require from time to time (the
            "BORROWING BASE CERTIFICATE"), Agent will credit Baldwin with the
            lesser of: (i) seventy-five percent (75%) of the net amount of the
            Eligible Accounts which are, absent error or other discrepancy,
            listed in such Borrowing Base Certificate ("ELIGIBLE ACCOUNT
            Availability"); and (ii) Eight Million Five Hundred Thousand and
            00/100 Dollars ($8,500,000.00). For purposes hereof, the net amount
            of Eligible Accounts at any time shall be the face amount of such
            Eligible Accounts LESS any and all returns, discounts (which may, at
            Agent's option, be calculated on shortest terms), credits, rebates,
            allowances, or excise taxes of any nature at any time issued, owing,
            claimed by Account Debtors, granted, outstanding, or payable in
            connection with such Accounts at such time.

                  (ii) ELIGIBLE INVENTORY. On receipt of each Borrowing
            Base Certificate, Agent will credit Baldwin with the lesser of: (i)
            sixty-five percent (65%) of the Value of Eligible Inventory which
            is, absent error or other discrepancy, listed in such Borrowing Base
            Certificate, and (ii) Seventeen Million and 00/100 Dollars
            ($17,000,000.00)."

      5.    LETTERS OF CREDIT. Effective immediately upon consummation of the
Sale (as defined in Section ), Article 4 of the Credit Agreement shall be
amended to add Section 4.9 to read in its entirety as follows:

            "Section 4.9 REQUIREMENTS AFTER TERMINATION OF AGREEMENT.
      Upon termination of the Agreement, whether at stated maturity or by
      acceleration, Borrower shall deposit in a non-interest bearing, blocked
      deposit account at Fifth Third Bank to which only the Agent will have
      access (the "LOC Account"), and Agent is hereby authorized to draw,
      advance or disburse under the Agreement, a sum in immediately available
      funds equal to the aggregate

<PAGE>   3


                                      -3-


      amount of all of the issued and outstanding Letters of Credit. The LOC
      Account will secure solely Borrower's obligations under the Letters of
      Credit and Borrower hereby grants to Agent, for the benefit of the
      Lenders, a security interest in such funds and the LOC Account and all
      interest, income, proceeds, investments and reinvestments thereof.
      Borrower agrees that after the termination of the Notes, Agent is hereby
      authorized to liquidate such account (or any part thereof) and apply the
      proceeds as reimbursement for the amount of such drawing or payment under
      or with respect to the Letters of Credit. The LOC Account shall continue
      until such time as the Letters of Credit shall expire or have been
      terminated . At such time, any part of the funds remaining in the Account
      shall be remitted to Borrower and discharged from the security interest
      granted hereby. Notwithstanding the foregoing provisions of this Section
      4.9, Borrower shall not be required to establish the LOC Account or
      deposit funds therein upon termination of this Agreement with respect to
      any issued and outstanding Letter of Credit that is secured by a letter of
      credit from another financial entity reasonably acceptable to Lenders (it
      being understood that General Electric Capital Corporation or First Union
      National Bank, or affiliates of either such entity which issue letters of
      credit in the ordinary course of business, are acceptable to Lenders)."

      6.    CONTINUATION OF WAIVER. (a) The Agent and the Lenders hereby consent
to waive the application of Section 10.3(a)(iv) of the Credit Agreement solely
as it relates to the four quarter period ending September 30, 1999; PROVIDED,
HOWEVER, that this waiver shall expire on the earlier of (i) March 29, 2000 and
(ii) the date on which good faith negotiations between Borrower and General
Electric Capital Corporation for the refinancing of the Loan shall cease.

            (b)   The Agent and the Lenders hereby consent to waive the
application of Section 10.3(a)(iv) of the Credit Agreement solely as it relates
to the four quarter period ending December 31, 1999; PROVIDED, HOWEVER, that
this waiver shall expire on the earlier of (i) March 29, 2000 and (ii) the date
on which good faith negotiations between Borrower and General Electric Capital
Corporation for the refinancing of the Loan shall cease.

      7.    SALE OF KAC AND SIGNATURE LEASING COMPANY. The Agent and the
Lenders hereby consent to the sale by Borrower of all of the stock of (i)
Keyboard Acceptance Corporation (f/k/a BPO Finance Corporation) a Delaware
corporation and a subsidiary of Borrower, and (ii) Signature Leasing Company, an
Ohio corporation and a subsidiary of Borrower, pursuant to that Stock Purchase
Agreement between Borrower and Duetsche Financial Services Corporation and dated
as of December 8, 1999 (the "Sale"); PROVIDED, HOWEVER, that the proceeds of the
Sale shall first be applied in the inverse order of maturity to the payment of
the remaining installments on the Term Loan, and at any time after the Term Loan
shall have been repaid in full, such proceeds shall be applied in repayment of
the Loan. For purposes of this Section , "Term Loan" shall mean the Obligations
as defined in the Amended and Restated Term Loan Agreement dated as of May 15,
1998, by and among Borrower, Agent and the Lenders thereto, as amended by the
First Amendment thereto dated as of July 15, 1999 and the Waiver and Second
Amendment thereto dated as of December 3, 1999.

      8.    REAFFIRMATION OF COVENANTS, WARRANTIES AND REPRESENTATIONS. Borrower
hereby agrees and covenants that all representations and warranties in the
Credit Agreement, including without limitation all of those warranties and
representations set forth in Article 9, are true and accurate as of the date
hereof. Borrower further reaffirms all covenants in the Credit Agreement, and
reaffirm each of the affirmative covenants set forth in Section 10.1, the
negative covenants set forth in Section 10.2 and the financial covenants set
forth in Section 10.3 thereof, as if fully set forth herein, except to the
extent modified by this Eighth Amendment.

      9.    CONDITIONS PRECEDENT TO CLOSING OF EIGHTH AMENDMENT. On or prior to
the closing of the Eighth Amendment (hereinafter the "Eighth Amendment Closing
Date"), each of the following conditions precedent shall have been satisfied:

            (a)   PROOF OF CORPORATE AUTHORITY. Agent shall have received from
      Borrower copies, certified by a duly authorized officer to be true and
      complete on and as of the Eighth Amendment Closing Date, of records of all
      action taken by Borrower to authorize (i) the execution and delivery of
      this Eighth Amendment and all other certificates, documents and
      instruments to which it is or is to become a party as contemplated or
      required by this Eighth Amendment, and (ii) its performance of all of its
      obligations under each of such documents.

            (b)   DOCUMENTS. Each of the documents to be executed and delivered
      at the Eighth Amendment Closing and all other certificates, documents and
      instruments to be executed in connection herewith shall have been duly and
      properly authorized, executed and delivered by Borrower and shall be in
      full force and effect on and as of the Eighth Amendment Closing Date.

            (c)   LEGALITY OF TRANSACTIONS. No change in applicable law shall
      have occurred as a consequence of which it shall have become and continue
      to be unlawful (i) for Agent and each Lender to perform any of its
      agreements or obligations under any of the Loan Documents, or (ii) for
      Borrower to perform any of its agreements or obligations under any of the
      Loan Documents.

            (d)   PERFORMANCE, ETC. Except as set forth herein, Borrower shall
      have duly and properly performed, complied with and observed each of its
      covenants, agreements and obligations contained in each of the Loan
      Documents. Except as set forth herein, no event shall have occurred on or
      prior to the Eighth Amendment Closing Date, and no condition shall exist
      on the Eighth Amendment Closing Date, which constitutes a Default or an
      Event of Default.

            (e)   CHANGES; NONE ADVERSE. Since the date of the most recent
      balance sheets of Borrower delivered to Agent, no changes shall have
      occurred in the assets, liabilities, financial condition, business,
      operations or prospects of Borrower which, individually or in the
      aggregate, are material to Borrower, and Agent shall have completed such
      review of the status of all current and pending legal issues as Agent
      shall deem necessary or appropriate.

of this Eighth Amendment and the handling of any other matters incidental
hereto.

not herein modified shall remain in full force and effect. In the event a term,
condition or provision of the Agreement conflicts with a term, condition or
provision of this Eighth Amendment, the latter shall govern.

construed and interpreted in accordance with the laws of the State of Ohio.

             (d) This Eighth Amendment shall be binding upon and shall inure to
the benefit of the parties hereto and their respective heirs, successors and
assigns.
