             HOREJSI TRUST EXTENDS TENDER OFFER FOR PCA COMMON STOCK
                      AND INCREASES PER SHARE OFFER PRICE

BOULDER,  CO.,  February 16, 2007 - The Mildred B. Horejsi  Trust ("The  Trust")
announced today that it has revised its tender offer for all outstanding  shares
of common stock of Putnam  California  Investment  Grade  Municipal Trust (AMEX:
PCA), a closed-end  fund trading on the American Stock  Exchange  ("AmEx") under
the ticker symbol "PCA" by extending  its tender offer  deadline to 5:30 Eastern
Standard Time, March 8, 2007. The Trust also announced that it has increased its
per share offer from $14.16 to $14.75,  or approximately  99% of PCA's per share
net asset value as of the close of trading on Thursday, February 15, 2007.

The Trust's  revised and  extended  offer to pay PCA's  shareholders  $14.75 per
share in cash, without interest, reflects a premium of approximately 2% over the
last sale price of $14.48,  as reported by the AmEx on  Thursday,  February  15,
2007, the previous  trading day's closing  price.  The Trust's offer to purchase
shares is greater  than the  highest  price that  shares on the AmEx have traded
since December, 2001. The Trust believes that the offer gives PCA's shareholders
a more  realistic  opportunity  to realize nearly 100% of their net asset value,
per share,  contrary  to the PCA's  trustees'  proposal to merge PCA into Putnam
California Tax Exempt Income Fund. According to PCA's trustees,  the proposal to
open-end   and  merge  PCA  into  this  other   fund  would  give   shareholders
approximately  99% of their net asset value,  per share, if the proposal musters
enough  shareholder  votes. The Trust intends to vote any shares acquired in the
Offer against an such proposal.

Stewart R. Horejsi,  a  spokesperson  for the Trust,  stated that:  "This is the
highest price paid for shares of PCA since December of 2001. Our offer gives PCA
shareholders a chance to realize almost the full net asset value of their shares
now and move PCA into a new direction.  Although PCA's trustees are offering 99%
of the NAV of PCA's shares (based on their  proposal which includes a maximum 1%
transaction  costs),  we firmly  believe  their  proposal will not garner enough
shareholder  votes to pass. We believe  strongly in this tender offer,  which is
why we are extending the deadline to tender  shares.  PCA's  trustees,  in their
response to our original  tender offer filing,  responded that the  shareholders
would be better served by moving their shares of PCA into an open-end  fund, the
Putnam  California  Tax Exempt Income Fund, a fund which has performed even more
abysmally  than  PCA!  This  does  not  serve  the  long-term  interests  of PCA
shareholders,  and is contrary to public  statements  by the trustees only a few
months ago when they stated that PCA should remain a closed-end fund."

"This is an opportunity for PCA's  shareholders to tender their shares of common
stock for  likely  more than what they paid for them," Mr.  Horejsi  added.  "We
expect  that  the  Trust  can do a  better  job than  the  current  advisor  and
administrator for PCA, and the trustees recent comments in response to our offer
only  underscore why we believe they are not serving the long-term  interests of
the shareholders of PCA."
