                  Committed Amount and/or the U.S. Term Loan Committed Amount,
                  and any other matters relevant thereto, all in form and
                  substance reasonably satisfactory to the U.S. Agent; and

                           (vi) if the reallocation, if any, of outstanding
                  Loans among the Lenders in connection with such increase
                  results in the prepayment of Eurodollar Loans on a day which
                  is not the last day of an Interest Period with respect
                  thereto, Airgas shall have paid to each affected Lender such
                  amounts, if any, as may be required pursuant to Section 4.11.

                  (e)      Upon the effectiveness of the increase in the

         pursuant to subsection (d), (i) the U.S. Commitment Percentage or the
         Canadian Commitment Percentage, as applicable, of each Lender shall be
         automatically adjusted to give effect to such increase, provided that
         the amount of each Lender's Revolving U.S. Commitment and Revolving
         Canadian Commitment (other than a



         Lender whose Revolving U.S. Commitment or Revolving Canadian Commitment
         shall have been increased in connection with such increase) shall
         remain unchanged, (ii) the Borrowers, the Agents and the Lenders will
         use all commercially reasonable efforts to assign and assume
         outstanding Loans of the affected category to conform the respective
         amounts thereof held by each Lender to the respective U.S. Commitment
         Percentage or the Canadian Commitment Percentage, as applicable, as so
         adjusted, it being understood that the parties hereto shall use
         commercially reasonable efforts to avoid prepayment or assignment of
         any affected Loan that is a Eurodollar Loan on a day other than the
         last day of the Interest Period applicable thereto and (iii) in the
         case of an increase in the U.S. Term Loan Committed Amount, beginning
         with the Principal Amortization Payment Date next succeeding the date
         of such increase, the amount of each Principal Amortization Payment on
         the U.S. Term Loans shall be increased by the minimum amount that, when
         allocated ratably (based on outstandings) among all of the Lenders
         holding U.S. Term Loans immediately after giving effect to such
         increase in the U.S. Term Loan Committed Amount, would provide
         (assuming all other things to be equal) for each of the Lenders holding
         U.S. Term Loans immediately prior to giving effect to such increase in
         the U.S. Term Loan Committed Amount to receive in connection with such
         Principal Amortization Payment an amount at least equal to the amount
         that such Lender would have received had such increase in the U.S. Term
         Loan Committed Amount (and the corresponding adjustment to such
         Principal Amortization Payment pursuant to this Section 4.4(e)) not
         taken place.
