                     THIS CONCERNS YOUR EXISTING INVESTMENT

                                       IN

               PUTNAM CALIFORNIA INVESTMENT GRADE MUNICIPAL TRUST

                               (AMEX TICKER: PCA)

 WE HAVE INCREASED OUR OFFER PRICE, AND NOW ARE OFFERING YOU $14.75 PER SHARE OF
 COMMON STOCK. THIS IS THE HIGHEST PRICE PER SHARE SINCE DECEMBER, 2001 AND IS
              99% OF PCA'S NET ASSET VALUE AS OF FEBRUARY 15, 2007!

            WE HAVE ALSO EXTENDED OUR OFFER DEADLINE TO MARCH 8, 2007

        READ THE FOLLOWING CAREFULLY AS IT IMPACTS YOUR INVESTMENT IN PCA

THESE ARE THE KEY REASONS WE BELIEVE YOU SHOULD ACT ON OUR OFFER:

     1.   OUR OFFER OF $14.75 IS THE  HIGHEST  PRICE PAID PER SHARE OF PCA SINCE
          DECEMBER, 2001.

     2.   YOU WILL  RECEIVE  APPROXIMATELY  99% OF THE NET  ASSET  VALUE OF YOUR
          SHARES IN CASH,  NOW.  PCA'S  TRUSTEES  PROPOSE  TO GIVE YOU THIS SAME
          AMOUNT  SOMETIME IN JUNE, IF THE MERGER OF PCA INTO PUTNAM  CALIFORNIA
          TAX EXEMPT INCOME FUND ACTUALLY PASSES.(1)

     3.   WE INTEND TO VOTE  AGAINST  THE  PROPOSED  MERGER AND WILL  ATTEMPT TO
          BLOCK THE MERGER OR ANY PROPOSAL TO OPEN-END  PCA. THIS MEANS THAT THE
          TRUSTEES'  PROPOSAL  TO GIVE YOU 99% OF THE NAV OF YOUR  SHARES OF PCA
          MAY NOT OCCUR.

     4.   OUR  PROPOSAL  TO GIVE YOU 99% OF THE NAV OF YOUR  SHARES NOW WILL NOT
          REQUIRE YOU TO PAY ANY REDEMPTION FEES OR ANY BROKERAGE COMMISSIONS.

     5.   PCA'S  MERGER  PROPOSAL  WILL RESULT IN YOUR ASSETS  BEING PLACED IN A
          FUND WHICH PERFORMED  WORSE THAN ITS APPLICABLE  BENCHMARK INDEX FOR 6
          OUT OF THE PAST 7 CALENDAR YEARS AND  UNDERPERFORMED  PCA FOR 5 OF THE
          LAST 7 YEARS!  A PROPOSAL TO MERGE OUR SHARES INTO A  WORSE-PERFORMING
          FUND IS NOT IN OUR BEST INTEREST.

     6.   IF WE ARE  SUCCESSFUL IN ACQUIRING A MAJORITY OF PCA'S COMMON  SHARES,
          WE WILL PROPOSE CHANGES,  INCLUDING  REPLACING THE CURRENT  INVESTMENT
          ADVISER AND CHANGING PCA'S INVESTMENT OBJECTIVES,  THAT WILL RESULT IN
          PCA BEING FAR DIFFERENT THAN THE INVESTMENT YOU BOUGHT.

     7.   IF SHAREHOLDERS APPROVE THESE CHANGES, PCA WILL NO LONGER BE AN INCOME
          FUND. IT WILL LIQUIDATE ITS ENTIRE  PORTFOLIO OF CALIFORNIA  MUNICIPAL
          BONDS  AND ANY  INCOME  WILL NO  LONGER BE  EXEMPT  FROM  FEDERAL  AND
          CALIFORNIA INCOME TAX.

IF YOU DON'T WANT TO BE PART OF THIS NEW  DIRECTION,  OUR TENDER OFFER GIVES YOU
AN  OPPORTUNITY  TO SELL YOUR SHARES AT 99% OF NAV,  NOW,  WHICH IS WHAT YOU MAY
HAVE IN JUNE UNDER THE TRUSTEE'S MERGER PROPOSAL.

                       THE OFFER EXPIRES ON MARCH 8, 2007
