      WHEREAS, the Borrower, the Lenders and the Agent desire to amend the
Credit Agreement in order to amend certain provisions thereof;

      NOW, THEREFORE, in consideration of the premises and the undertakings set
forth herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

      1. DEFINITIONS. Capitalized terms used herein and not otherwise defined
herein shall have the meanings attributed to them in the Credit Agreement.

      2. AMENDMENTS TO CREDIT AGREEMENT.

            (a) The definition of "Termination Date" set forth in Article I of
      the Credit Agreement is hereby amended and restated to read in its
      entirety as follows:

                  "TERMINATION DATE" means the earlier of (a) July 31, 2001, and
            (b) the date of termination of the Aggregate Commitment pursuant to
            SECTION 2.4 hereof or the Commitments pursuant to SECTION 9.1
            hereof."

            (b) Sections 2.3(B) and 2.4 of the Credit Agreement are hereby
      amended and restated to read in their entirety as follows:

            "(B)  MANDATORY PREPAYMENTS.

                  "(i) AGGREGATE COMMITMENT EXCEEDED. If at any time and for any
      reason the Revolving Credit Obligations are greater than the Aggregate
      Commitment, the Borrower shall immediately make a mandatory prepayment of
      the Obligations in an amount equal to such excess. In addition, if
      Revolving Credit Availability is at any time less than the amount of
      contingent L/C Obligations outstanding at any time, the Borrower shall
      deposit cash collateral with the Agent in an amount equal to the amount by
      which such L/C Obligations exceed such Revolving Credit Availability. All
      of the mandatory prepayments made under this SECTION 2.3(B) shall be
      applied first to Floating Rate Loans and to any Eurodollar Rate Loans
      maturing on such date and then to subsequently maturing Eurodollar Rate
      Loans in order of maturity.
<PAGE>
                  "(ii) ASSET DISPOSITIONS. Promptly following any Asset
      Disposition, the Borrower shall prepay the Revolving Loans in an aggregate
      amount equal to one hundred percent (100%) of the net cash proceeds
      derived from such Asset Disposition, and the Aggregate Commitment shall be
      automatically reduced, ratably among the Lenders, by the amount of such
      prepayment. For purposes of this Section 2.3(b)(ii), the term "ASSET
      DISPOSITION" shall mean the disposition of any or all of the assets
      (including the capital stock of a Subsidiary) of the Borrower or any of
      its Subsidiaries, whether by sale, lease, transfer or otherwise, but
      excluding the sale, transfer, or other disposition of any inventory in the
      ordinary course of business and on ordinary business terms.

            "2.4  REDUCTION OF COMMITMENTS.

            "(i) OPTIONAL REDUCTION OF COMMITMENTS. The Borrower may permanently
      reduce the Aggregate Commitment in whole, or in part ratably among the
      Lenders, in an aggregate minimum amount of $5,000,000 and integral
      multiples of $5,000,000 in excess of that amount (unless the Aggregate
      Commitment is reduced in whole), upon at least three (3) Business Days'
      written notice to the Agent, which notice shall specify the amount of any
      such reduction; PROVIDED, HOWEVER, that the amount of the Aggregate
      Commitment may not be reduced below the aggregate principal amount of the
      outstanding Revolving Credit Obligations.

            "(ii) AUTOMATIC REDUCTION OF COMMITMENTS. The Aggregate Commitment
      shall be permanently reduced, ratably among the Lenders, by the amount of
      each prepayment required to be made in accordance with Section 2.3(B)(ii).

            "(iii) PAYMENT OF COMMITMENT FEES. All accrued commitment fees shall
      be payable on the effective date of any partial or complete termination of
      the obligations of the Lenders to make Revolving Loans hereunder."

            (c) SECTION 2.12(D)(II) of the Credit Agreement is hereby amended to
      read in its entirety as follows:

                  "(ii) The Applicable Eurodollar Margin, Applicable Floating
            Rate Margin and Applicable Commitment Fee Percentage shall be
            determined by reference to the table set forth below for each
            calendar quarter, commencing with the quarter ending on September
            30, 2000.

            (d) Subparagraph (ii) of Section 7.3(F) of the Credit Agreement is
      hereby amended to read in its entirety as follows:

                  "(ii) [Intentionally Blank];"

            (e) The period after subparagraph (h) of Section 7.3(G)(iii) shall
      be changed to a semicolon, the word "and" shall be inserted thereafter and
      a new subparagraph (i) shall be added to Section 7.3(G)(iii) after
      paragraph (h), reading in its entirety as follows:

                  "(i) for each Acquisition made on or after July 1, 2000, the
            written consent of all Lenders shall have been obtained."

            (f) Sections 7.4(A), (B) and (D) of the Credit Agreement are hereby
      amended to read in their entirety as follows:

            "(A) FIXED CHARGE COVERAGE RATIO. The Borrower shall maintain a
      ratio ("FIXED CHARGE COVERAGE RATIO") of (i) the sum of (a) EBITDA, MINUS
      (b) depreciation expense, to the extent included in the computation of
      EBITDA to (ii) the sum of (a) Interest Expense, PLUS (b) one-seventh of
      the outstanding balance of the Loans made pursuant to Section 2.1(a) and
      2.1(b) hereof and outstanding at the end of each relevant four
      fiscal-quarter period, PLUS (c) scheduled amortization of the principal
      portion of any Indebtedness (except to the extent included in clause (b)
      preceding), in each case for the Borrower and its consolidated
      Subsidiaries, at least equal to the minimum Fixed Charge Coverage Ratio
      set forth below at all times during each period set forth opposite such
      minimum Fixed Charge Coverage Ratio:

      MINIMUM FIXED CHARGE
         COVERAGE RATIO            PERIOD

            0.57 to 1.00           April 1, 2000 through September 30, 2000

            0.60 to 1.00           October 1, 2000 through December 31, 2000

            0.70 to 1.00           January 1, 2001 through March 31, 2001

            0.85 to 1.00           From and after April 1, 2001

                                     Page 3
<PAGE>
      In each case the Fixed Charge Coverage Ratio shall be determined as of the
      last day of each fiscal quarter for the four fiscal-quarter period ending
      on such day. For purposes of calculating the Fixed Charge Coverage Ratio
      for any period under this SECTION 7.4(A), Interest Expense and
      amortization of Indebtedness shall be calculated for any such period by
      including the actual amount for the applicable period ending on such day,
      including Interest Expense and amortization of assumed Indebtedness
      attributable to Permitted Acquisitions occurring during such period on an
      actual basis for assumed Indebtedness and on a PRO FORMA basis for
      Interest Expense for the period from the first day of the applicable
      period through the date of the closing of each Permitted Acquisition,
      utilizing (a) where available or required pursuant to the terms of this
      Agreement, historical audited and/or reviewed unaudited financial
      statements obtained from the seller, broken down by fiscal quarter in the
      Borrower's reasonable judgment or (b) unaudited financial statements
      (where no audited or reviewed financial statements are required pursuant
      to the terms of this Agreement) reviewed internally by the Borrower,
      broken down by fiscal quarter in the Borrower's reasonable judgment,
      utilizing, without duplication, any pro forma adjustments which are
      consistent with the Commission's regulations and practices as of June 24,
      1998 (whether or not applicable) to account for adjustments to historical
      Interest Expense for an acquired entity.

            "(B) TOTAL DEBT TO EBITDA RATIO. The Borrower shall not permit the
      ratio (the "LEVERAGE RATIO") of (i) Total Debt of the Borrower and its
      consolidated Subsidiaries to (ii) EBITDA of the Borrower and its
      consolidated Subsidiaries to be greater than the maximum Leverage Ratio
      set forth below at any time during each period set forth opposite such
      maximum Leverage Ratio:

            MAXIMUM LEVERAGE RATIO    PERIOD

            6.30 to 1.00              April 1, 2000 through June 30, 2000

            6.10 to 1.00              July 1, 2000 through September 30, 2000,

            5.35 to 1.00              October 1, 2000 through December 31, 2000,

            5.00 to 1.00              January 1, 2001 through March 31, 2001,

            4.15 to 1.00              From and after April 1, 2001.

      The Leverage Ratio shall be, in each case, determined as of the last day
      of each fiscal quarter (commencing with the fiscal quarter ending June 30,
      2000, and each fiscal quarter thereafter) based upon (a) for Total Debt,
      Total Debt as of the last day of each such fiscal quarter; and (b) for
      EBITDA, EBITDA for the twelve-month period ending on such day, calculated
      as set forth in the definition thereof.

                                     Page 4

            "(D) CAPITAL EXPENDITURES. The Borrower will not, nor will it permit
      any Subsidiary to, expend, or be committed to expend, for Capital
      Expenditures in the acquisition of fixed assets, (i) during the calendar
      year 2000, an amount in excess of $2,800,000, in the aggregate, nor (ii)
      during the calendar year 2001, an amount in excess $2,000,000, in the
      aggregate. For purposes of this SECTION 7.4(D), the Capital Expenditures
      for all Subsidiaries during the applicable twelve-month period are to be
      included, even though some of such Capital Expenditures occurred prior to
      such entity becoming a Subsidiary of the Borrower."

            (g) A new paragraph (E) is hereby added to Section 7.4 reading in
      its entirety as follows:

                  "(E) MINIMUM EBITDA. The EBITDA of the Borrower and its
            consolidated Subsidiaries for each fiscal quarter ended on or after
            September 30, 2000 shall not be less than $3,250,000."

            (h) A new paragraph (q) shall be added to Section 8.1 reading in its
      entirety as follows:

                  "(q) PAYMENT OF SUBORDINATED INDEBTEDNESS. The Borrower, any
            of its Subsidiaries or any Guarantor shall make any payment of
            principal of any Indebtedness subordinated in payment to any of the
            Obligations at any time prior to the later of (i) the Termination
            Date or (ii) the payment in full of the Obligations and the
            expiration, cancellation or termination of all Letters of Credit."

      3. WAIVER. The Lenders hereby agree that the failure of Borrower or any of
its Subsidiaries prior to the Termination Date to make any payment when due with
respect to Permitted Subordinated Indebtedness shall not constitute an Event of
Default under the Credit Agreement, notwithstanding the provisions of Section
8.1(e) of the Credit Agreement.

      4. REPRESENTATIONS AND WARRANTIES. In order to induce the Agent and the
Lenders to enter into this Amendment, the Borrower hereby represents and
warrants to the Agent and the Lenders as of the date of this Amendment that:

of the Credit Agreement and the other Loan Documents (a) shall remain unaltered,
(b) shall continue to be, and shall remain, in full force and effect in

      (and all indirect references such as "hereby", "herein", "hereof" and
      "hereunder") shall be deemed to be references to the Credit Agreement as
      amended by this Amendment.

      6. AMENDMENT FEE. The Borrower agrees to pay to each Lender, within two
business days after execution of this Amendment by the Borrower and all the
Lenders, an amendment fee equal to fifteen one-hundredths of one percent (0.15%)

      different parties hereto on separate counterparts each of which, when so
      executed and delivered, shall be deemed an original, and all of which
      taken together shall constitute one and the same agreement.
