</TABLE>

         For purposes hereof, the term "Pricing Date" means, for any fiscal
         quarter of the Borrower ending on or about March 31, 2002, the date on
         which the Administrative Agent is in receipt of the Borrower's most
         recent financial statements for the fiscal quarter then ended (and in
         the case of the year-end financial statements, audit report),






                                      -2-
<PAGE>

         pursuant to Section 8.5 hereof. The Applicable Margin shall be
         established based on the Total Funded Debt/EBITDA Ratio for the most
         recently completed fiscal quarter and the Applicable Margin established
         on a Pricing Date shall remain in effect until the next Pricing Date.
         If the Borrower has not delivered its financial statements (and, in the
         case of the year-end financial statements, audit report) by the date
         such financial statements are required to be delivered under Section
         8.5 hereof, until such financial statements are delivered, the
         Applicable Margin shall be the highest Applicable Margin (i.e., the
         Total Funded Debt/EBITDA Ratio shall be deemed to be greater than 4.5
         to 1.0). If the Borrower subsequently delivers such financial
         statements before the next Pricing Date, the Applicable Margin
         established by such late delivered financial statements shall take
         effect from the date of delivery until the next Pricing Date. In all
         other circumstances, the Applicable Margin established by such
         financial statements shall be in effect from the Pricing Date that
         occurs immediately after the end of the fiscal quarter covered by such
         financial statements until the next Pricing Date. Each determination of
         the Applicable Margin made by the Administrative Agent in accordance
         with the foregoing shall be conclusive and binding on the Borrower and
         the Lenders if reasonably determined.

         1.3. The definitions of "EBITDA", "L/C Commitment" and "Revolving
Credit Commitment" appearing in Section 5.1 of the Credit Agreement shall each
be amended and restated in its entirety to read as follows:

                  "EBITDA" means, with respect to any period, Net Income for
         such period plus (A) all amounts deducted in arriving at such Net
         Income in respect of (a) Interest Expense, plus (b) federal, state,
         local, and foreign income taxes for such period, plus (c) amounts
         properly charged for depreciation of fixed assets and amortization of
         intangible assets during such period, plus (d) any charges to Net
         Income during such period which are non-cash, non-recurring expenses
         arising from the rationalization of the Borrower's facilities, product
         lines or personnel, up to a maximum amount equal to 10% of Net Worth at
         the end of such period, plus (e) any charges to Net Income during such
         period (up to $15,000,000 in the aggregate during the term of this
         Agreement, including any such charges accrued prior to the Effective
         Date) associated with the Intermatic Litigation, plus (f) for any
         fiscal quarter ending after January 1, 2002, any non-cash expenses
         incurred with respect to its Plans during such period, plus (g) for any
         fiscal quarter ending after January 1, 2002, any cash expenses incurred
         with respect to its Plans during such period up to a maximum amount of
         $500,000 minus (B) the sum of (a) any recapture, recoveries, or other
         credits to Net Income during such period associated with the Intermatic
         Litigation and (b) any recapture, recoveries or other credits to Net
         Income during such period incurred with respect to its Plans; provided,
         however, that EBITDA for the relevant period shall be calculated on a
         pro forma basis in good faith by the Borrower and established to the
         reasonable satisfaction of the Administrative Agent as if each
         Permitted Acquisition which occurred during such period had taken place
         on the first day of such period (including adjustments for
         non-recurring expenses and income reasonably determined by the Borrower
         in good faith and established to the reasonable satisfaction of the
         Administrative Agent). In the event that any such non-cash charge is
         excluded from the computation of EBITDA for a given period pursuant to
         clause (d) above but the circumstances giving rise to such charge have
         a cash impact in a



                                      -3-
<PAGE>

         subsequent period which would have reduced EBITDA but for the charge in
         the prior period, such impact shall be taken into account in computing
         EBITDA in the period when such impact occurs.

                  "L/C Commitment" means $31,000,000, as reduced pursuant to the
         terms hereof; provided, however, that the L/C Commitment shall be
         increased to $38,500,000 so long as (i) the Letters of Credit issued to
         the entity providing the supersedeas bond in connection with the
         Intermatic Litigation remain outstanding, and (ii) the Letter of Credit
         to be issued to Intermatic, Inc. has been issued and remains
         outstanding.

                  "Revolving Credit Commitment" means, as to any Lender, the
         obligation of such Lender to make Revolving Loans and to participate in
         Letters of Credit issued for the account of the Borrower hereunder in
         an aggregate principal or face amount at any one time outstanding not
         to exceed the amount set forth opposite such Lender's name on Schedule
         1 attached hereto and made a part hereof, as the same may be reduced or
         modified at any time or from time to time pursuant to the terms hereof.
         The Borrower and the Lenders acknowledge and agree that the Revolving
         Credit Commitments of the Lenders aggregate $125,000,000 upon the
         effectiveness of the Second Amendment hereto.

         1.4. Subsection (a) of Section 8.5 shall be amended and restated in its
entirety to read as follows:

                   (a) (i) for each monthly accounting period ending on or
         before December 31, 2003, as soon as available, and in any event within
         30 days after the close of each fiscal month, a copy of the
         consolidated balance sheet of the Borrower and its Subsidiaries as of
         the last day of such period and the consolidated statements of income,
         retained earnings, and cash flows of the Borrower and its Subsidiaries
         for the fiscal month and for the fiscal year-to-date period then ended,
         each in reasonable detail and showing in comparative form the figures
         for the corresponding date and period in the previous fiscal year,
         prepared by the Borrower in accordance with GAAP (subject to the
         absence of footnote disclosures and year-end audit adjustments) and
         certified to by its chief financial officer or another officer of the
         Borrower acceptable to the Administrative Agent and (ii) from and after
         January 1, 2004, as soon as available, and in any event within 45 days
         after the close of each of the first three fiscal quarters of each
         fiscal year, a copy of the consolidated balance sheet of the Borrower
         and its Subsidiaries as of the last day of such period and the
         consolidated statements of income, retained earnings, and cash flows of
         the Borrower and its Subsidiaries for the fiscal quarter and for the
         fiscal year-to-date period then ended, each in reasonable detail and
         showing in comparative form the figures for the corresponding date and
         period in the previous fiscal year, prepared by the Borrower in
         accordance with GAAP (subject to the absence of footnote disclosures
         and year-end audit adjustments) and certified to by its chief financial
         officer or another officer of the Borrower acceptable to the
         Administrative Agent;

         officer of the Borrower acceptable to the Administrative Agent, to the
         effect that to the best of such officer's knowledge and belief no
