  (a) Percentages indicated are based on portfolio market value.

  (b) The aggregate identified cost on a tax basis is $45,285,651,
      resulting in gross unrealized appreciation and depreciation of $1,737,575
      and $694,345, respectively, or net unrealized appreciation of $1,043,230.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
      be the most recent ratings available at July 31, 2004 for 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 agencies would ascribe to these securities at July 31,
      2004. Securities rated by Putnam are indicated by "/P".

      total market value of restricted securities held at July 31, 2004 was
      $1,241,250 or 2.7% of portfolio market value.

      The rates shown on IFB's, which are securities paying interest rates that
      vary inversely to changes in the market interest rates, are the current
      interest rates at July 31, 2004.

      Security valuation Tax-exempt bonds and notes are valued at fair value on
      the basis of valuations provided by an independent pricing service,
      approved by the Trustees.  Such services use information with respect to
      transactions in bonds, quotations from bond dealers, market transactions
      in comparable securities and various relationships between securities in
      determining value.  Other investments, including restricted securities,
      are valued at fair value following procedures approved by the Trustees.
      Such valuations and procedures are reviewed periodically by the Trustees.
