"Second Amendment Effective Date") upon its execution and delivery by the
Required Banks and the Borrowers.

                  added to the otherwise  applicable rate during the Adjustment
                  Period.

<PAGE>

                                      -2-

                           ADJUSTMENT PERIOD. The period from March 15, 2000
                  through September 14, 2000, provided that no Event of Default
                  has occurred and is continuing. If an Event of Default has
                  occurred and is continuing, the Adjustment Period shall
                  continue until such Event of Default has been cured to the
                  satisfaction of the Required Banks.

                           PREMIUM PERIOD. March 15, 2000 through March 15,
                  2001."

         (b) deleting the last paragraph of the definition of "Applicable Rate"
therein and restating it as follows:

                           "Each Applicable Rate shall become effective on the
                  first day after receipt by the Banks of financial statements
                  delivered pursuant to Sections 7.4(a) or (b) hereof which
                  indicate a change in the Pricing Ratio and in the Applicable
                  Rate in accordance with the above table, PROVIDED that for the
                  period from the Effective Date through six (6) months from the
                  Effective Date, the Applicable Rate shall be Level IV,
                  PROVIDED FURTHER that during the Adjustment Period, the
                  Adjusted Margin shall be added to the Applicable Rate for
                  Loans across all Levels in the above table and to the
                  Acceptance Fee for Bankers' Acceptances. If at any time the
                  financial statements required to be delivered pursuant to
                  Sections 7.4(a) or (b) hereof are not delivered within 10 days
                  after the time periods specified in such subsections, the
                  Applicable Rate shall be the rate set forth for Level IV PLUS
                  the Adjusted Margin, if applicable, subject to adjustment upon
                  actual receipt of such financial statements. In the event that
                  after the Effective Date and by March 31, 2000, the Parent
                  shall have received Net Equity Proceeds of at least
                  $100,000,000 from the Equity Offering, the Applicable Rate for
                  Loans across all Levels in the above table and the Acceptance
                  Fee for Bankers' Acceptances will be reduced by 0.250%,
                  provided that under no circumstance shall the Applicable Rate
                  for Base Rate Loans, Canadian Base Rate Loans or Canadian
                  Prime Rate Loans be less than the Base Rate, Canadian Base
                  Rate or Canadian Prime Rate, as applicable."

         and (c) deleting the following definition in its entirety and restating
it as follows:

                           "LETTER OF CREDIT PERCENTAGE. The percentage per
                  annum equal to the margin above the Eurodollar Rate charged on
                  Revolving Credit Eurodollar Rate Loans, as in effect from time
                  to time, as set forth in the column "Applicable Rate for
                  Revolving Credit Eurodollar Rate Loans" in the Applicable Rate
                  table above, PLUS the Adjusted Margin, if applicable."

         3. AMENDMENTS TO SECTION 4A.4.2 OF THE CREDIT AGREEMENT. Section 4A.4.2
of the Credit Agreement is hereby amended by deleting Section 4A.4.2 in its
entirety and restating it as follows:

                  "Section 4A.4.2. PAYMENT PROVISIONS. Each prepayment of the
         Term Loan required by this Section 4A.4 shall be allocated among the
         Term Loan Lenders in accordance with each such Bank's Term Loan
         Percentage. Any prepayment of principal of the Term Loan shall include
         all interest accrued to the date of

                                      -3-

          prepayment and shall be applied against the scheduled installments of
          principal due on the Term Loan in the inverse order of maturity. No
          amount repaid with respect to the Term Loan may be reborrowed. Any
          Term Loan Lender may decline to accept any payments due to such Term
          Loan Lender pursuant to this Section 4A.4. Any such payments declined
          with respect to Section 4A.4.1(a) shall be used to repay the Domestic
          Revolving Credit Loans (but not permanently reduce the Total
          Commitment) on a pro rata basis.

                  In the event that any prepayment under Sections 4A.4.1 (a),
          (c), (d) or (e) is made during the Premium Period, a prepayment
          premium of 1.00% (the "Prepayment Premium") on the amount prepaid
          shall be payable by the Borrowers to the Administrative Agent for the
          benefit of the Term Loan Lenders; PROVIDED that, if such prepayment is
          required as a result of Section 4A.4.1(b), no such Prepayment Premium
          shall be required. The Administrative Agent agrees to pay to the Term
          Loan Lenders any Prepayment Premium received under this Section 4A.4.2
          PRO-RATA in accordance with their Term Loan Percentages."

          4. AMENDMENTS TO SECTION 4A.5 OF THE CREDIT AGREEMENT. Section 4A.5 of
the Credit Agreement is hereby amended by deleting Section 4A.5 in its entirety

          Borrowers shall have the right at any time to prepay the Term Notes on
          or before the Term Loan Maturity Date, as a whole, or in part, upon
          not less than three (3) Business Days prior written notice to the
          Administrative Agent, without premium or penalty (other than the
          obligation to reimburse the Term Loan Lenders and the Administrative
          Agent pursuant to Section 5.14 hereof, or as otherwise stated herein),
          PROVIDED that (i) each partial prepayment shall be in the principal
          amount of $1,000,000 or an integral multiple of $500,000 thereof, (ii)
          each partial prepayment shall be allocated among the Term Loan Lenders
          in accordance with such Bank's Term Loan Percentage, and (iii) in the
          event that any prepayment under this Section 4A.5 is made during the
          Premium Period, the Prepayment Premium on the amount prepaid shall be
          payable by the Borrowers to the Administrative Agent for the benefit
          of the Term Loan Lenders PRO-RATA in accordance with their Term Loan
          Percentages. Any prepayment of principal of the Term Loan shall
          include all interest accrued to the date of prepayment and shall be
          applied against the scheduled installments of principal due on the
          Term Loan in the inverse order of maturity. No amount repaid with
          respect to the Term Loan may be reborrowed."

          5. AMENDMENTS TO SECTION 4A.6.1 OF THE CREDIT AGREEMENT. Section

         Loan or such portion thereof shall bear interest during such Interest
         Period at the rate of 2.000% per annum PLUS the Adjusted Margin, if
         applicable (the "Term Loan Base Rate Margin") above the Base Rate.

                                      -4-

                  (b) At the option of the Domestic Borrowers, and upon notice
         given to the Administrative Agent pursuant to Section 4A.6.2, so long
         as no Default or Event of Default has occurred or is continuing, to
         the extent that all or any portion of the Term Loan bears interest
         during such Interest Period at the Eurodollar Rate, the Term Loan or
         such portion shall bear interest during such Interest Period at the
         rate of 3.500% per annum (the "Term Loan Eurodollar Margin") above the
         Eurodollar Rate PLUS the Adjusted Margin, if applicable."

         6. RATIFICATION, ETC. Except as expressly amended hereby, the Credit
Agreement, the other Loan Documents and all documents, instruments and
agreements related thereto are hereby ratified and confirmed in all respects and
