         that the aggregate amount of the Commitments of the Lenders shall be
         deemed used from time to time to the extent of the aggregate amount of
         the B Advances then outstanding and such deemed use of the aggregate

         in effect from time to time, the Borrower may borrow under this Section
         2.01, repay pursuant to Section 2.06 or prepay pursuant to Section 2.09

         of the proposed A Borrowing if it is comprised of Base Rate Advances,
         or the third Business Day prior to the date of the proposed A Borrowing
         if it is comprised of A Advances of any other Type", and

             (ii) the fourth and fifth sentences thereof to read as follows:

              "Each Lender shall, before 1:00 P.M. (New York City time) on the

         (g) Section 2.03(a)(v) is hereby amended by adding to the end thereof
    the following sentence:

         "The failure of any Lender to make the B Advance to be made by it, if
         any, as part of any B Borrowing shall not relieve any other Lender of
         its obligation, if any, hereunder to make the B Advance to be made by
         such other Lender, if any, on the date of such B Borrowing, but no
         Lender shall be responsible for the failure of any other Lender to make
         the B Advance, if any, to be made by such other Lender on the date of
         any B Borrowing."

         by law, in such federal court.  The Borrower hereby also consents to
         the service of copies of the summons and complaint and any other
         process which may be served in any such action or proceeding by the
         mailing of copies of such summons, complaint and other process to the
         Borrower at its address specified in Section 8.02.  The Borrower agrees
         that a final, non-appealable judgment in any such action or proceeding
         shall be conclusive and may be enforced in other jurisdictions by suit
         on the judgment or in any other manner provided by law.  Nothing in
         this Agreement shall affect any right that the Borrower, any Lender or
         the Agent may otherwise have to bring any action or proceeding relating
         to this Agreement or the Notes in the courts of any other jurisdiction.

              (b) The Borrower irrevocably and unconditionally waives, to the
         fullest extent it may legally and effectively do so, any objection that
         it may now or hereafter have to the laying of venue of any action or
         proceeding arising out of or relating to this Agreement or the Notes in
         any New York State or federal court.  The Borrower hereby irrevocably
         waives, to the fullest extent permitted by law, the defense of any
         inconvenient forum to the maintenance of such action or proceeding in
         any such court.
