      MILDRED B. HOREJSI TRUST REQUESTS INJUNCTION AGAINST THE TRUSTEES OF
             THE PUTNAM CALIFORNIA INVESTMENT GRADE MUNICIPAL TRUST

BOULDER,  CO.,  March 21,  2007 - The  Mildred B.  Horejsi  Trust (the  "Mildred
Trust")  announced  today that it has filed a complaint in  Massachusetts  state
court against the trustees of the Putnam  California  Investment Grade Municipal
Trust  ("PCA")  [AMEX:  PCA]  seeking  an  injunction  to  halt's  PCA's  forced
liquidation  plan  announced  with no warning on Monday.  The Mildred Trust also
seeks to stop the PCA trustees from closing PCA's  transfer books and suspending
trading in PCA shares.

PCA's  trustees  announced  on Monday that they plan to liquidate  PCA,  without
seeking shareholder  approval of the liquidation,  and that they plan on closing
PCA's  transfer  books and  suspending  trading of PCA's  shares at the close of
business on Monday, March 26, 2007. The Mildred Trust believes these actions, on
such short notice and without PCA  shareholder  approval,  violate the governing
documents of PCA and are  expressly  for the purpose of  preventing  the Mildred
Trust from closing its current  tender offer at $15 per share and purchasing any
PCA  shares.  These  actions  will  prevent  PCA  shareholders  from  having the
opportunity  to tender their shares at a price greater than PCA's current market
price or PCA's net asset value.  The Mildred  Trust  believes  that the trustees
have  violated  their duties to  shareholders  by taking these  actions,  to the
detriment of PCA's shareholders.

Mr. Stewart Horejsi, spokesperson for the Mildred Trust, stated that "We believe
PCA's  trustees have breached  their  fiduciary  duties by forcing a liquidation
plan on shareholders,  on short notice and without a shareholder vote, that will
likely  result in  shareholders  receiving  less for their shares than the price
offered by the Mildred Trust in its tender offer.  Putnam already got in trouble
with various regulatory agencies before with their poor management and fiduciary
oversight of shareholder assets; it appears that they are doing it again."

Mr.  Horejsi  added that,  "even if PCA's  assets can be sold for their full net
asset value ($14.92 per share as of close of trading on March 20, 2007, which is
8 cents less per share  than the tender  offer  price of $15.00 per  share),  we
believe the costs of liquidation  will reduce the amount PCA  shareholders  will
receive to an amount below net asset value. In addition,  shareholders  will not
receive liquidation proceeds until sometime in April at the earliest, as opposed
to receiving  tender offer  proceeds in March under the Mildred  Trust's  tender
offer.  The Mildred  Trust does not believe the PCA trustees  can justify  their
position that a forced  liquidation in which shareholders will receive less than
the tender offer price is somehow in the best interests of PCA  shareholders  as
compared with the  opportunity  to  participate  in the Mildred  Trust's  tender
offer."

Mr.  Horejsi  noted that "as recently as last fall,  the PCA  trustees  took the
position that it was not in the best interests of PCA  shareholders to open-end,
liquidate  or merge PCA.  Then,  early in 2007 the PCA  trustees  decided that a
merger  into an open-end  Putnam was  advisable.  Now,  without  submitting  any
options to PCA  shareholders,  the PCA trustees have once again reversed  course
and  taken  steps  to  liquidate  PCA,  while at the same  time  soliciting  PCA
shareholders to continue to leave their  investment  under Putnam's  management.
The only thing that these  scorched earth steps are designed to accomplish is to
prohibit shareholders from participating in the Mildred Trust's tender offer."

Unless a court order prohibiting PCA's liquidation plan is obtained, the Mildred
Trust will be unable to close its tender offer,  as, among other  things,  PCA's
shares  cannot  be  transferred  after the close of  business  on March 26.  The
Mildred  Trust's  tender  offer is  currently  scheduled  to expire at 5:30 p.m.
Eastern time on March 27.
