                  For outstanding Advances under each of the Facilities, the
                  Applicable Margin for each Advance shall be determined by
                  reference to the Performance Level in effect on the first day
                  of each Interest Period for such Advance. Changes in the
                  Applicable Margin resulting from changes in the Performance
                  Level shall become effective (for purposes of this definition
                  only, the date of such effectiveness being the "EFFECTIVE
                  DATE") as of the first day following the last day of the most
                  recent Fiscal Quarter or Fiscal Year for which (A) financial
                  statements are delivered to the Lender pursuant to Section
                  7(e)(ii) or (iii) of the Parent Guaranty and (B) a certificate
                  of the chief financial officer of the Guarantor is delivered
                  by the Guarantor to the Lender setting forth, with respect to
                  such financial statements, the then-applicable Performance
                  Level and the basis of the calculations therefor, and shall
                  remain in effect until the next change to be effected pursuant
                  to this definition; PROVIDED that, (i) if the Borrower shall
                  have made any payments in respect of interest during the
                  period (for purposes of this definition only, the "INTERIM
                  PERIOD") from and including the Effective Date to the day on
                  which any change in Performance Level is determined as
                  provided above, then the amount of the next such payment of
                  interest due by the Borrower on or after such day shall be
                  increased or decreased by an amount equal to any underpayment
                  or overpayment so made by the Borrower during such Interim
                  Period and (ii) each determination of the Performance Level
                  pursuant to this definition shall be made with respect to the
                  Measurement Period ending at the end of the fiscal period
                  covered by the relevant financial statements.

                           Anything in this definition or elsewhere in this
                  Agreement to the contrary notwithstanding, if the "Applicable
                  Margin" at any "Performance Level" for "Eurodollar Rate
                  Advances" outstanding under either (i) the "Term A Facility"
                  or (ii) the "Revolving Credit Facility" under, and as defined
                  in, the Guarantor Credit Agreement, is increased by any
                  amendment or other modification to the Guarantor Credit
                  Agreement, the corresponding Applicable

<PAGE>

                  Margin under this Agreement shall be increased to be equal
                  to the sum of such "Applicable Margin" as so increased plus
                  0.250% per annum, it being understood for purposes of
                  determining the corresponding Applicable Margin under this
                  Agreement, that the Applicable Margin for Advances
                  outstanding under the Term Facility corresponds to the
                  "Applicable Margin" for "Eurodollar Rate Advances" under
                  the "Term A Facility" under, and as defined in, the
                  Guarantor Credit Agreement, that the Applicable Margin for
                  Advances outstanding under the Working Capital Facility
                  corresponds to the "Applicable Margin" for "Eurodollar Rate
                  Advances" under the "Revolving Credit Facility" under, and
                  as defined in, the Guarantor Credit Agreement, and that the
                  Performance Level I, Performance Level II, Performance
                  Level III, Performance Level IV, Performance Level V and
                  Performance Level VI under this Agreement correspond to
                  "Performance Level I", "Performance Level II", "Performance
                  Level III", "Performance Level IV", "Performance Level V"
                  and "Performance Level VI", respectively, under and as
                  defined in the Guarantor Credit Agreement. Any such
                  increase in the Applicable Margin at any Performance Level
                  for any outstanding Advance under this Agreement resulting
                  from an increase of the corresponding "Applicable Margin"
                  under and as defined in the Guarantor Credit Agreement
                  shall become effective as of the effective date of such
                  increase under the Guarantor Credit Agreement, and shall
                  remain in effect until such Applicable Margin is further
                  increased as a result of the further increase, if any, of
                  the corresponding "Applicable Margin" under and as defined
                  in the Guarantor Credit Agreement.

                  (b) The following new definitions are added in Section 1.01 in
         appropriate alphabetical order:
