     Borrower may request from time to time, and subject to the terms and
     conditions hereinafter set forth, that the Aggregate Commitment be
     increased by giving written notice thereof to the Administrative Agent;
     provided, however, that any such notice must be given no later than 60 days
     prior to the then Facility Termination Date.  Each such notice (a "Notice
     of Commitment Increase") shall be in the form of Exhibit C-2 and specify
     therein:

               (i) the effective date of such increase, which date (the

          than five Business Days after receipt by the Administrative Agent of
          such notice;

               (ii) the amount of the requested increase; provided, however,
          that after giving effect to such requested increase, the Aggregate

          such requested increase will be the same or greater than their
          respective Percentages prior to giving effect to such requested
          increase (each such then Lender being a then "Increasing Lender"),

          amount such that its Lender's Percentage after giving effect to such a
          requested increase will be less than its Lender's Percentage prior to
          giving effect to such requested increase (each such Lender being a
          "Partially Increasing Lender") and the identity of each financial

          acceptable to the Administrative Agent and each such assignee being a

          documentation embodying the provisions of the Notice of Commitment
          Increase relating to the increase in the Aggregate Commitment to be
          effected on such Commitment Increase Effective Date; and

               (ii) upon acceptance of such documentation by the Administrative
          Agent, which acceptance shall not be unreasonably withheld, and so
          long as no Default or Unmatured Default has occurred and is
          continuing, (A) the Administrative Agent shall give prompt notice of
          such acceptance to each Lender, (B) it shall become effective, and the

          Administrative Agent shall record each New Lender's information in the
          Register, and the Borrower shall execute and deliver to each then New
          Lender, upon written request by such New Lender, a Committed Note

          Committed Note, if any, a new Committed Note in the face principal
          amount equal to such Lender's Commitment after giving effect to such
          Commitment increase.

     On each Commitment Increase Effective Date:

               (i) each then New Lender and each then Increasing Lender shall,
          by wire transfer of immediately available funds, deliver to the
          Administrative Agent such Lenders' New Funds Amount for such
          Commitment Increase Effective Date, which amount, for each such
          Lender, shall constitute Committed Loans made by such Lender to the
          Borrower pursuant to Section 2.1 on such Commitment Increase Effective
          Date; and

               (ii) the Administrative Agent shall, by wire transfer of
          immediately available funds, pay to each then Reducing Lender and to
          each Partially Increasing Lender its Reduction Amount for such
          Commitment Increase Effective Date, which amount, for each such
          Lender, shall constitute a prepayment by the Borrower pursuant to
          Section 2.9, ratably in accordance with the respective principal
          amounts thereof, of the principal amounts of all then outstanding
          Committed Loans of such Lender.

     then Increasing Lender's and each then Partially Increasing Lender's
     information in the Register.  Also effective as of each Commitment Increase
     Effective Date, each then New Lender and each then Increasing Lender shall
     be deemed to have purchased and had transferred to it, and each then
     Reducing Lender and each Partially Increasing Lender shall be deemed to

     undivided interest and participation in such Reducing Lender's and such
     Partially Increasing Lender's interest and participation in all then
     outstanding Letters of Credit, the obligations of the Borrower with respect
     thereto and any security therefor and any guaranty pertaining thereto at
     any time existing as is necessary so that such undivided interests and
     participations of all Lenders (including each then New Lender) shall accord
     with their respective Lender's Percentages after giving effect to the
     increase in the Aggregate Commitment on such Commitment Increase Effective
     Date."
