          of all the Lenders, as reduced from time to time pursuant to the

          Corporate Base Rate is a reference rate and does not necessarily
          represent the lowest or best rate of interest actually charged to
          any customer. Bank One may make commercial loans or other loans at
          rates of interest at, above or below the Corporate Base Rate."

          Period, and having a maturity equal to such Interest Period,
          PROVIDED that, (i) if Reuters Screen FRBD is not available to the
          Agent for any reason, the applicable Eurodollar Base Rate for the
          relevant Interest Period shall instead be the applicable British
          Bankers' Association Interest Settlement Rate for deposits in U.S.
          dollars as reported by any other generally recognized financial
          information service as of 11:00 a.m. (London time) two Business
          Days prior to the first day of such Interest Period, and having a
          maturity equal to such Interest Period, and (ii) if no such British
          Bankers' Association Interest Settlement Rate is available to the
          Agent, the applicable Eurodollar Base Rate for the relevant
          Interest Period shall instead be the rate determined by the Agent
          to be the rate at which Bank One or one of its Affiliate banks
          offers to place deposits in U.S. dollars with first-class banks in
          the London interbank market at approximately 11:00 a.m. (London

          annum equal to the higher of (a) the Corporate Base Rate for such
          day, and (b) the sum of the Federal Funds Effective Rate for such
          day PLUS 1/2% per annum; PROVIDED, that `Floating Rate' means, for
          any day for the period from November 15, 1999 to January 15, 2000,
          a rate of interest per annum equal to the highest of (i) the
          Corporate Base Rate for such day, (ii) the sum of the Federal Funds
          Effective Rate for such day plus 1/2% per annum and (iii) the sum
