      the securities listed. Ratings are generally ascribed to
      securities at the time of issuance. While the agencies may from
      time to time revise such ratings, they undertake no obligation to
      do so, and the ratings do not necessarily represent what the

      interest rates, are the current interest rates at January 31,
      2005.

      registration under Rule 144A of the Securities Act of 1933. These
      securities may be resold in transactions exempt from registration,

      various relationships between securities in determining value.
