          A.M., Local Time, on the Borrowing Date requested by such Canadian

          Such borrowing will then be made available to the relevant Canadian
          Borrower by the Administrative Agent crediting the account of such
          Canadian Borrower on the books of such Administrative Office with the
          aggregate of the amounts made available to the Administrative Agent by
          the

          institutions to purchase at par, pursuant to Section 13.6(d), all or
          part of such Non-Extending Lender's Commitment and outstanding Loans
          on the basis as if such Non-Extending Lender had extended the
          Termination Date in accordance with subsection 5.3(b)(i), together
          with accrued but unpaid interest, Commitment Fees and all other
          amounts then due and payable to such Non-Extending Lender, including,
          without limitation, amounts payable pursuant to Section 5.12, in which
          case such Non-Extending Lender shall, promptly upon request by

          Loan Party in respect of any payment under this Agreement the Loan
          Party shall notify the Administrative Agent in writing with respect
          thereto (including with respect to the rate of Non-Excluded Taxes to
          be withheld and remitted by the Loan Party and whether any increased
          amount is payable by a Loan Party pursuant to this section 5.11(a) or
          otherwise) prior to any such payment being made to the Administrative
          Agent or any Lender or Designated Auction Loan Provider."

          by adding the following after the end of the first sentence thereof:

          "Notwithstanding anything herein to the contrary, "Confidential
