                           performance of any acquired entity ("Earn-Outs") to
                           any other person or entity). For purposes of this

                           calculated, except without giving effect to the
                           EBITDA of any of Company or its Subsidiaries (each an
                           "Unaudited Subsidiary") for which the Purchaser has

                           each Unaudited Subsidiary.

                  (ii) FIXED CHARGE COVERAGE RATIO. The ratio as of each
         Calculation Date of the consolidated (and combined, if applicable)
         Modified EBITDA LESS the amount of any Earn-Outs (as that term is
         defined herein) not financed with the proceeds of loans or other
         borrowings from any person or entity ("Unfinanced Earn-Outs"), cash
         taxes ("Cash Taxes") and Capital Expenditures of Company and its
         Subsidiaries not financed with the proceeds of loans or other
         borrowings from any person or entity ("Unfinanced Capital
         Expenditures"), which Unfinanced Earn-Outs, Cash Taxes and Unfinanced
         Capital Expenditures were incurred during the immediately preceding
         four (4) fiscal quarters of Company and its Subsidiaries divided by the
         sum of consolidated (and combined, if applicable) current maturities of
         Funded Debt for Company and its Subsidiaries PLUS any and all dividends
         paid or accrued by Company and its Subsidiaries PLUS all Fixed Charges

<PAGE>

         September 30, 2000; and 1.10 to 1.00 as of the Calculation Date
         occurring on September 30, 2000, and thereafter until, but not
         including, the Calculation Date occurring on December 31, 2000; and
         1.20 to 1.00 as of the Calculation Date occurring on December 31, 2000,

         5.1(h):

                  "(iv) SENIOR DEBT TO EBITDA. The ratio as of each Calculation
         Date of the sum of consolidated (and combined, if applicable) PNC
         Senior Debt and other Senior Debt as of each Calculation Date divided

         its Subsidiaries immediately preceding the applicable Calculation Date
         shall not be greater than 4.60 to 1.00 as of the Calculation Date

                    reference to "September 30, 1999" and substituting therefor
                    "June 30, 2000" in each case.

                    1.6       By adding the following new Section 5.2(k):

                  "(k) EARN-OUT PAYMENTS. Except for the $1,000,000.00 Earn-Out
         payment paid to Mr. Thomas on February 29, 2000, and financed (i.e.,
         not an Unfinanced Earn-Out) with the proceeds of the recent equity
         offering by Company, Company shall not, and shall not permit any of its
         Subsidiaries to, make any payment with respect to any Earn-Out at any

         of Company and its Subsidiaries, as such ratio is more particularly
         described in Section 5.1(h)(ii) of this Agreement, is less than or
         equal to 1.10 to 1.00 as of the Calculation Date immediately preceding
         the date any such Earn-Outs are due and payable."

                        CONSENT OF INDIVIDUAL GUARANTORS

         Notwithstanding the provisions of that certain Subordination and
Intercreditor Agreement, dated July 8, 1999, among PNC Bank, Company and GE
Capital, if any amounts have become payable or have been paid by any Individual
Guarantor under the Guaranty Agreement, each Individual Guarantor agrees that
the rights of such Individual Guarantor, in respect of such monies, to seek to
enforce repayment, obtain the benefit of any security or exercise any other
rights or legal remedies of any kind which may accrue to such Individual
Guarantor against the Company or any of its Subsidiaries, whether by way of
subrogation, offset, counterclaim or otherwise, in respect of the amount so
payable or so paid (or in respect of any monies for the time being due to such
Guarantor from Company or any of its Subsidiaries) shall be pari passu with the
rights of GE Capital in respect of the Obligations if and for so long as any
Obligations shall be outstanding.
