                                                               November 30, 1996

Dear Trust Shareholder:

     Interest  rate  volatility  in the domestic  fixed income  markets was once
again a major factor over the past twelve months. Significant swings in the pace
of U.S.  economic  growth  influenced  the bond market's  performance,  as every
release of economic  data led to market  participant  speculation  regarding the
direction of Federal Reserve monetary policy.

     Despite strong growth and rising wage pressures,  the Fed's decision not to
raise  interest  rates at their two most recent  policy  meetings  has  markedly
increased the stakes in the bond market. The rationale behind the Fed's decision
not to raise  interest  rates  appears  to focus on the  benign  inflation  data
released  during the third quarter.  Should  economic  growth slow and inflation
remain  benign,  the Fed will be proven correct in their inaction and the market
would be expected to rally significantly. On the other hand, signs of a stronger
economy could result in weaker bond prices as the likelihood of a Fed tightening
would increase.

     BlackRock  maintains a positive  view on the bond market.  On balance,  the
outlook for moderate inflation remains intact,  suggesting that further declines
in  interest  rates  are  likely.  In  addition  to this  favorable  fundamental
backdrop,  foreign  demand  for U.S.  bonds  has  increased  due to the  renewed
attractiveness of the U.S. bond market on a global basis.

     This  annual  report  is  designed  to help you stay  informed  about  your
investment and represents our ongoing  commitment to improving our communication
with  you.  We hope  you find  this  report  useful  now and in the  future.  We
appreciate  your confidence and look forward to helping you reach your long-term
investment goals.


Sincerely,



/s/ Laurence D. Fink                            /s/ Ralph L. Schlosstein

Dear Shareholder:

     We are pleased to present the annual  report for The  BlackRock  California
Investment  Quality Municipal Trust Inc. ("the Trust") for the fiscal year ended
October 31, 1996. We would like to take this  opportunity  to review the Trust's
stock price and net asset value (NAV) performance, summarize market developments
and discuss recent portfolio management activity.

     The Trust is a non-diversified, actively managed closed-end bond fund whose
shares are traded on the American  Stock  Exchange  under the symbol "RAA".  The
Trust's  investment  objective is to provide high current  income that is exempt
from  regular   federal  and  California   income  taxes   consistent  with  the
preservation of capital.  The Trust seeks to achieve this objective by investing
in  investment  grade  (rated  "AAA"  to "BBB" by a major  rating  agency  or of
equivalent  quality)  municipal debt securities  issued by local  municipalities
throughout California.

     The Trust has  exhibited  superior  performance  on a reinvested  net asset
value total return basis for the 1-year period ended October 31, 1996. The Trust
was the top  performing  fund in its Lipper peer group of California  Closed-End
Funds for the year,  finishing  #1 of 27 funds  according  to Lipper  Analytical
Services Inc. The table below  summarizes the changes in the Trust's stock price
and net asset value over the past year:

     On July 1, 1996,  the Trust's  Board of Directors  announced an increase in
the Trust's monthly dividend to $0.07 per share ($0.84 annualized) from $0.06560
per  share  ($0.7872  annualized)  effective  with the July  31,  1996  dividend
payment.  This  increase  was made in  accordance  with the  Trust's  investment
objective  to provide  high  monthly  income  exempt  from  regular  Federal and
California  income taxes  consistent  with the  preservation  of capital.  After
careful  evaluation of the Trust's current and anticipated net investment income
levels,  the Board  determined  that the Trust  could  sustain  higher  dividend
payments to shareholders.


THE FIXED INCOME MARKETS

     Significant  swings  in the pace of U.S.  economic  growth  influenced  the
performance  of the fixed  income  markets  over the past year.  Throughout  the
fourth  quarter  of  1995  and  through  the  first  six  weeks  of  1996,  weak
inflationary  data and sluggish  retail demand  spurred two  reductions of short
term interest rates  totaling 50 basis points (0.50%) by the Federal  Reserve to
5.25%. In response to these reductions, as well as the sharp decline in interest
rates  throughout  1995,  economic growth began to pick up in  mid-February  and
accelerated  throughout the second quarter of 1996.  Economic growth as measured
by Gross  Domestic  Product  (GDP) was  measured at an  annualized  4.7% for the
second quarter of 1996,  which led investors to believe that the Federal Reserve
would be forced  to raise  interest  rates for the first  time in over a year to
curb the pace of the economy.  However,  the pace of economic  growth has slowed
during the past few months. Softer economic data and continued moderation in the
broad  inflation  measures  during the third  quarter of 1996 allowed the Fed to
leave short term interest rates  unchanged at their August and September  policy
meetings.

     After  lagging the  performance  of their taxable  counterparts  during the
fourth quarter of 1995,  year-to-date  municipal

                                       2
<PAGE>

bond  performance  as measured by the Lehman  Municipal  Bond Index has outpaced
that of taxable bonds  (represented  by the Lehman  Aggregate  Index)  returning
2.99% versus 2.84% for taxables.  This strong  performance  is the result of the
relative  scarcity of new municipal bond issuance combined with increased retail
demand due to the end of "flat tax" reform  concerns.  In particular,  the third
quarter  of 1996  witnessed  approximately  $60  billion in cash (in the form of
calls, maturities and interest payments) returned to investors and recycled back
into the  municipal  bond market.  As the quarter  progressed,  however,  retail
demand  moderated  in response to a  strengthening  stock  market and  declining
interest rate levels.  Within the municipal market,  longer maturity  municipals
outperformed  shorter  maturities for the year ended October 31, as the yield of
the 30-year AAA General Obligation (G.O.) bond fell four basis points (0.04%) to
5.54% while yields of shorter  maturities rose. 

     The California  economy continued its recovery over the past year,  leading
us to have a favorable outlook for the state and its debt market. In particular,
the  state's  credit  outlook is  positive,  as the morass of the Orange  County
debacle retreats from the minds of investors. Though California new issuance has
been moderate, good fundamental conditions in the market have allowed California
municipal bonds to outperform the national markets.  Of note is Proposition 218,
which was passed by California voters in November.  This proposition would limit
the ability of  municipalities  to raise fees for services  and public  projects
(e.g.  new tolls and  community  charges for  projects) by requiring  two-thirds
majority  voter  approval.  This  measure  is  currently  being  challenged  and
interpreted in the California legal system. It is not clear how this proposition
will  affect the  California  municipal  bond  market;  however,  it will almost
certainly limit the future revenue-generating capacity of municipalities.

     Looking  ahead to the fourth  quarter  and into  1997,  the  potential  for
weakening  supply and demand  technicals has led us to take a cautious stance on
the  municipal  market.  The  recent  decline  in  interest  rates  may spur new
issuance,  which  historically  is  heaviest  in the  fourth  quarter as issuers
complete year-end business. Additionally, although the likelihood of radical tax
reform has  diminished  since the first half of 1996, we continue to monitor the
possibility  of tax cuts over the next year and  their  potential  impact on the
municipal  bond  market.  We view any  potential  fourth  quarter  weakness as a
opportunity to add at attractive levels.

THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY

     The Trust's portfolio is actively managed to diversify  exposure to various
sectors,  issuers,  revenue sources and security types.  BlackRock's  investment
strategy  emphasizes  a  relative  value  approach,  which  allows  the Trust to
capitalize  upon  changing  market  conditions  by rotating  municipal  sectors,
credits and coupons.

     Additionally,  the Trust  employs  leverage at about 35% of total assets to
enhance its income by borrowing at short term municipal  rates and investing the
proceeds in longer maturity issues which have higher yields. The degree to which
the Trust can  benefit  from its use of  leverage  may affect its ability to pay
high  monthly  income.  The Federal  Reserve's  decision  not to increase  short
interest rates at their August and September  policy  meetings has benefited the
Trust,  as short term  municipal  rates (which  determine the Trust's  borrowing
costs) fell.

     The Trust has generally  favored  callable  premium coupon bonds throughout
the past twelve  months,  as they  characteristically  outperform par bonds in a
rising interest rate  environment.  Though interest rates have fallen  recently,
the  generally  upward  trend in rates  since  the  beginning  of 1996  proved a
favorable  environment to hold these  defensively  structured  bonds.  The Trust
maintained its focus in the  intermediate  portion of the municipal yield curve,
with nearly half of the Trust's holdings having an average life between 8 and 12
years.  Additionally,  the Trust's  credit  quality  bias  emphasizes  a barbell
strategy,  as the  majority of the  holdings  carry  either a "AAA" or "A"/"BBB"
credit  rating.  Limited  municipal bond supply has resulted in the narrowing of
yields spreads between higher- and lower-quality  municipal bonds. Should credit
spreads tighten  significantly  from current levels,  thereby reducing the yield
advantage of owning a lower rated bond, we would seek to reallocate  some of the
Trust's "BBB" issues into higher rated bonds at tighter spreads.

THE BLACKROCK CALIFORNIA INVESTMENT
QUALITY MUNICIPAL TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1. ACCOUNTING                       The  BlackRock   California  Investment
POLICIES                                 Quality  Municipal  Trust   Inc.   (the
                                         "Trust") was  organized in  Maryland on
April 12, 1993 as a non-diversified  closed-end  management  investment company.
The Trust had no  transactions  until May 27, 1993 when it sold 7,093  shares of
common  stock  for  $100,012  to  BlackRock  Financial  Management,  Inc.,  (the
"Adviser"). Investment operations commenced on June 4, 1993.

  The Trust's investment objective is to provide high current income exempt from
regular  federal  and  California   state  income  taxes   consistent  with  the
preservation  of capital.  The ability of issuers of debt securities held by the
Trust to meet their obligations may be affected by economic  developments in the
state, a specific industry or region. No assurance can be given that the Trust's
investment objective will be achieved.

  The following is a summary of significant  accounting policies followed by the
Trust.

SECURITIES VALUATION:  Municipal securities  (including  commitments to purchase
such  securities  on a  "when-issued"  basis)  are valued on the basis of prices
provided  by  a  pricing  service  which  uses   information   with  respect  to
transactions  in bonds,  quotations  from bond dealers,  market  transactions in
comparable   securities  and  various   relationships   between   securities  in
determining values. Any securities or other assets for which such current market
quotations  are not readily  available are valued at fair value as determined in
good faith under procedures established by and under the general supervision and
responsibility of the Trust's Board of Directors.

  Short-term  securities which mature in more than 60 days are valued at current
market  quotations.  Short-term  securities  which mature in 60 days or less are
valued at amortized  cost, if their term to maturity from date of purchase is 60
days or less,  or, by amortizing  their value on the 61st day prior to maturity,
if their original term to maturity from date of purchase exceeded 60 days.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME:  Securities  transactions  are
recorded  on the trade  date.  Realized  and  unrealized  gains and  losses  are
calculated  on the  identified  cost basis.  Interest  income is recorded on the
accrual  basis and the Trust  accretes  original  issue  discounts  or amortizes
premium on securities purchased using the interest method.

FEDERAL INCOME TAXES: For federal income tax purposes, the Trust is treated as a
separate taxpaying entity. It is the intent of the Trust to continue to meet the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies  and to  distribute  all of its net income to  shareholders.  For this
reason and because  substantially  all of the Trust's  gross income  consists of
tax-exempt interest, no federal income tax provision is required.

DIVIDENDS  AND  DISTRIBUTIONS:   The  Trust  declares  and  pays  dividends  and
distributions to common  shareholders  monthly from net investment  income,  net
realized short-term capital gains and other sources, if necessary. Net long-term
capital  gains,  if any,  in excess  of loss  carryforwards  may be  distributed
annually.  Dividends and  distributions  are recorded on the  ex-dividend  date.
Dividends and distributions to preferred shareholders are accrued and determined
as described in Note 4. Deferred  Organization  Expenses: A total of $16,000 was
incurred in connection with the organization of the Trust. These costs have been
deferred and are being amortized  ratably over a period of sixty months from the
date the Trust commenced investment operations.

RECLASSIFICATION  OF  CAPITAL  ACCOUNTS:  The Trust  accounts  and  reports  for
permanent differences between financial and tax reporting in accordance with the
American Institute of Certified Public Accountants' Statement of Position, 93-2:
Determination,  Disclosure  and  Financial  Statement  Presentation  of  Income,
Capital Gain and Return of Capital  Distributions by Investment  Companies.  The
effect of  applying  the  statement  for the year ended  October 31, 1996 was to
increase accumulated net realized loss and increase undistributed net investment
income by $3,486.  Net investment income, net realized gains and net assets were
not affected by this change.

ESTIMATES:  The preparation of financial statements in conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

NOTE 2. AGREEMENTS                       The  Trust has  an  Investment Advisory
                                         Agreement  with  BlackRock    Financial
Management,  Inc., (the "Adviser"),  a wholly-owned  corporate subsidiary of PNC
Asset  Management  Group,  Inc., the holding company for PNC's asset  management
businesses  and  an   Administration   Agreement  with  Prudential  Mutual  Fund
Management LLC ("PMF"), an indirect,  wholly-owned  subsidiary of The Prudential
Insurance Company of America.

  The investment fee paid to the Adviser is computed  weekly and payable monthly
at an annual rate of 0.35% of the Trust's average weekly net investment  assets.
The  administration  fee paid to PMF is also computed weekly and payable monthly
at an annual rate of 0.10% of the Trust's average weekly net investment assets.

  Pursuant to the agreements, the Adviser provides continuous supervision of the
investment  portfolio and pays the compensation of officers of the Trust who are
affiliated  persons of the Adviser.  PMF pays occupancy and certain clerical and
accounting costs of the Trust. The Trust bears all other costs and expenses.


NOTE 3. PORTFOLIO                        Purchases  and  sales  of    investment
SECURITIES                               securities,   other  than    short-term
                                         investments,   for  the   year   ended
October 31, 1996 aggregated $15,629,074 and $15,352,510, respectively.

  The federal  income tax basis of the Trust's  investments  at October 31, 1996
was  substantially   the  same  as  the  basis  for  financial   reporting  and,
accordingly,  net  unrealized  appreciation  for federal income tax purposes was
$1,019,872   (gross   unrealized   appreciation--$1,043,480;   gross  unrealized
depreciation--$23,608).

  For federal income tax purposes,  the Trust had a capital loss carryforward at
October  31,  1996  of  approximately   $817,000  which  will  expire  in  2002.
Accordingly, no capital gain distribution is expected to be paid to shareholders
until net gains have been realized in excess of such amount.

NOTE 4. CAPITAL                          There are  200 million  shares of $.01 
                                         par value common  stock authorized.  Of
the 1,007,093  shares  outstanding  at October 31, 1996, the Adviser owned 7,093
shares.  As of October 31, 1996 there were 300 shares of Preferred  Stock Series
W7 outstanding.

  Offering costs ($104,994)  incurred in connection with the underwriting of the
Trust's  common stock have been  charged to paid-in  capital in excess of par of
the common stock.

  The Trust may classify or reclassify any unissued  shares of common stock into
one or more series of preferred  stock. On July 29, 1993 the Trust  reclassified
150 shares of common stock and issued a series of Auction Market Preferred Stock
("Preferred  Stock") Series W7. The Preferred  Stock had a liquidation  value of
$50,000 per share plus any  accumulated  but unpaid  dividends.  On May 16, 1995
shareholders approved a proposal to split each share of Preferred Stock into two
shares and  simultaneously  reduce  each  share's  liquidation  preference  from
$50,000 to $25,000 plus any  accumulated but unpaid  dividends.  The stock split
occurred on July 24, 1995.

  Underwriting  discounts  ($112,500) and offering costs  ($75,344)  incurred in
connection  with the  Preferred  Stock  offering  have been  charged  to paid-in
capital in excess of par of the common stock.

  Dividends  on Series W7 are  cumulative  at a rate which is reset every 7 days
based on the results of an auction.  Dividend  rates  ranged from 3.00% to 4.95%
during the year ended October 31, 1996.

  The Trust may not declare  dividends or make other  distributions on shares of
common  stock or purchase  any such  shares if, at the time of the  declaration,
distribution,  or  purchase,  asset  coverage  with  respect to the  outstanding
Preferred Stock would be less than 200%.

  The Preferred  Stock is redeemable at the option of the Trust,  in whole or in
part, on any dividend  payment date at $25,000 per share plus any accumulated or
unpaid dividends whether or not declared. The Preferred Stock is also subject to
mandatory  redemption  at  $25,000  per  share  plus any  accumulated  or unpaid
dividends,  whether or not  declared  if certain  requirements  relating  to the
composition  of the  assets  and  liabilities  of the  Trust as set forth in the
Articles of Incorporation are not satisfied.

  The  holders of  Preferred  Stock have voting  rights  equal to the holders of
common stock (one vote per share) and will vote  together with holders of shares
of common stock as a single class. However,  holders of Preferred Stock are also
entitled to elect two of the Trust's  directors.  In  addition,  the  Investment
Company Act of 1940 requires that along with approval by stockholders that might
otherwise  be  required,  the  approval  of the  holders  of a  majority  of any
outstanding  preferred shares, voting separately as a class would be required to
(a) adopt any

                                       11
<PAGE>

plan of reorganization  that would adversely affect the preferred shares and (b)
take any action  requiring a vote of security  holders,  including,  among other
things,  changes in the Trust's  subclassification  as a  closed-end  investment
company or changes in its fundamental investment restrictions.

NOTE 5. DIVIDENDS                         Subsequent  to October 31,  1996,  the
                                          Board  of   Directors   of  the  Trust
declared a  dividend  from  undistributed  earnings  of $0.07 per  common  share
payable November 30, 1996 to shareholders of record on November 15, 1996.


  For the period  November 1, 1996 to November 30, 1996,  dividends  declared on
Preferred  Stock  totalled  $21,648 in aggregate for the  outstanding  Preferred
Stock.

        THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC.
                         REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------


The Shareholders and Board of Directors of
The BlackRock California Investment Quality Municipal Trust Inc.:

     We have  audited  the  accompanying  statement  of assets and  liabilities,
including the portfolio of investments,  of The BlackRock California  Investment
Quality  Municipal Trust Inc. as of October 31, 1996 and the related  statements
of operations  for the year then ended and of changes in net  investment  assets
for each of the two years in the period then ended and the financial  highlights
for the each of the three years in the period then ended and for the period June
4, 1993  (commencement  of  investment  operations)  to October 31, 1993.  These
financial  statements  and financial  highlights are the  responsibility  of the
Trust's  management.  Our  responsibility  is to  express  an  opinion  on these
financial statements and financial highlights based on our audits.

     We conducted  our audit in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures included confirmation of securities owned at October
31, 1996 by  correspondence  with the custodian and brokers;  where replies were
not received from brokers, we performed other auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

     In our opinion,  such financial statements and financial highlights present
fairly,  in all  material  respects,  the  financial  position of The  BlackRock
California  Investment Quality Municipal Trust Inc. at October 31, 1996, and the
results of its  operations,  the  changes in its net  investment  assets and its
financial  highlights  for the  respective  stated  periods in  conformity  with
generally accepted accounting principles.

     Pursuant  to  the  Trust's   Dividend   Reinvestment   Plan  (the  "Plan"),
shareholders will  automatically have all distributions of dividends and capital
gains  reinvested  by State Street Bank and Trust  Company (the "Plan Agent") in
Trust  shares  pursuant to the Plan  unless an election is made to receive  such
amounts in cash.  The Plan Agent will effect  purchases of shares under the Plan
in the open market.  Shareholders  who elect not to participate in the Plan will
receive all  distributions in cash paid by check in United States dollars mailed
directly to the  shareholders  of record (or if the shares are held in street or
other  nominee  name,  then to the nominee) by the Transfer  Agent,  as dividend
disbursing agent.

     The Plan Agent serves as agent for the  shareholders in  administering  the
Plan.  After the Trust  declares a dividend or determines to make a capital gain
distribution,  the Plan Agent will, as agent for the  participants,  receive the
cash payment and use it to buy Trust shares in the open market,  on the American
Stock Exchange or elsewhere,  for the participants' accounts. The Trust will not
issue any new shares in connection with the Plan.

     Participants  in the Plan may withdraw from the Plan upon written notice to
the Plan Agent and will receive  certificates  for whole Trust shares and a cash
payment for any fraction of a Trust share.

     The Plan Agent's fees for the handling of the reinvestment of dividends and
distributions  will be paid by the Trust.  However,  each participant will pay a
pro rata  share of  brokerage  commissions  incurred  with  respect  to the Plan
Agent's open market  purchases in connection with the  reinvestment of dividends
and  distributions.  The automatic  reinvestment of dividends and  distributions
will not relieve  participants of any federal,  state or local income taxes that
may be payable on such dividends or distributions.

     Experience  under  the  Plan  may  indicate  that  changes  are  desirable.
Accordingly,  the Trust  reserves  the right to amend or  terminate  the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
change sent to all  shareholders of the Trust at least 90 days before the record
date for the dividend or distribution.  The Plan also may be amended by the Plan
Agent upon at least 90 days' written  notice to all  shareholders  of the Trust.
The Plan may be  terminated by the Plan Agent or the Trust upon at least 30 days
written notice to all shareholders of the Trust. All  correspondence  concerning
the Plan should be directed to the Plan Agent at (800)  699-1BFM.  The addresses
are on the front of this report.

        THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC.
                               INVESTMENT SUMMARY
- --------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE

The  BlackRock  California   Investment  Quality  Municipal  Trust's  investment
objective  is to provide  high current  income  exempt from regular  Federal and
California income tax consistent with the preservation of capital.

WHO MANAGES THE TRUST?

BlackRock  Financial  Management,  Inc.  ("BlackRock"  or the  "Adviser") is the
investment adviser for the Trust.  BlackRock is a registered  investment adviser
specializing in fixed income securities.  Currently,  BlackRock manages over $43
billion of assets  across the  government,  mortgage,  corporate  and  municipal
sectors.  These  assets are managed on behalf of  institutional  and  individual
investors in 21 closed-end funds traded on either the New York or American Stock
Exchanges,  several  open-end  funds and over 100 separate  accounts for various
clients  in the U.S.  and  overseas.  BlackRock  is a  subsidiary  of PNC  Asset
Management  Group  which is a division  of PNC Bank,  N.A.,  one of the  nations
largest banking organizations.


WHAT CAN THE TRUST INVEST IN?

Under normal  conditions,  the Trust expects to continue to manage its assets so
that at least  80% of its  investments  are  rated  investment  grade  ("BBB" by
Standard & Poor's and "Baa" by Moody's  Investor  Services) and up to 20% of its
assets may instead be deemed to be of equivalent  credit quality by the Adviser.
The Trust  intends to invest  substantially  all of the assets in a portfolio of
investment  grade   California   Municipal   Obligations,   which  include  debt
obligations  issued by or on behalf of California,  its political  subdivisions,
agencies and instrumentalities and by other qualifying issuers that pay interest
which, in the opinion of the bond counsel of the issuer,  is exempt from regular
Federal and California income tax. California  Municipal  Obligations are issued
to obtain funds for various  public  functions,  including the  construction  of
public facilities, the refinancing of outstanding obligations,  the obtaining of
funds for general operating expenses and for loans to other public  institutions
and facilities.


WHAT IS THE ADVISER'S INVESTMENT STRATEGY?

The Adviser will manage the assets of the Trust in  accordance  with the Trust's
investment  objective and policies to seek to achieve its objective by investing
in investment  grade  California  Municipal  Obligations.  The Adviser  actively
manages the assets in relation to market  conditions  and interest rate changes.
Depending  on yield and  portfolio  allocation  considerations,  the Adviser may
choose  to invest a  portion  of the  Trust's  assets  in  securities  which pay
interest that is subject to AMT (alternative  minimum tax). The Trust intends to
emphasize   investments  in  California  Municipal  Obligations  with  long-term
maturities and expects to maintain an average portfolio maturity of 15-20 years,
but the  average  maturity  may be  shortened  or  lengthened  from time to time
depending on market conditions.

Under current market conditions the use of leverage  increases the income earned
by the Trust.  The Trust  employs  leverage  primarily  through the  issuance of
preferred  stock.   Preferred  stockholders  will  receive  dividends  based  on
short-term rates in exchange for allowing the Trust to borrow additional assets.
These assets will be invested in longer-term assets which typically offer higher
interest  rates and the  difference  between the cost of the  dividends  paid to
preferred  stockholders  and the interest earned on the  longer-term  securities
will provide higher income levels for common  stockholders in most interest rate
environments.  The Trust issued  preferred  stock to leverage  the  portfolio at
approximately  35% of total assets.  See "Leverage  Considerations in the Trust"
below.

HOW ARE THE TRUST'S  SHARES  PURCHASED  AND SOLD?  DOES THE TRUST PAY  DIVIDENDS
REGULARLY?

The Trust's  shares are traded on the American  Stock  Exchange  which  provides
investors with  liquidity on a daily basis.  Orders to buy or sell shares of the
Trust must be placed through a registered broker or financial advisor. The Trust
pays monthly  dividends which are typically paid on the last business day of the
month. For shares held in the shareholder's name, dividends may be reinvested in
additional  shares of the fund through the Trust's transfer agent,  State Street
Bank and Trust Company. Investors who wish to hold shares in a brokerage account
should check with their financial  advisor to determine  whether their brokerage
firm offers dividend reinvestment services.

LEVERAGE CONSIDERATIONS IN THE TRUST

     Leverage  increases  the duration (or price  sensitivity  of the net assets
with respect to changes in interest  rates) of the Trust,  which can improve the
performance  of the fund in a  declining  rate  environment,  but can  cause net
assets to decline  faster in a rapidly  rising  interest rate  environment.  The
Trust may reduce,  or unwind,  the amount of leverage  employed should BlackRock
consider that  reduction to be in the best  interests of the Trust.  BlackRock's
portfolio managers  continuously monitor and regularly review the Trust's use of
leverage  and  maintain  the  ability to unwind the  leverage  if that course is
chosen.

SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO THE TRUST

THE TRUST IS  INTENDED  TO BE A  LONG-TERM  INVESTMENT  AND IS NOT A  SHORT-TERM
TRADING VEHICLE.

INVESTMENT  OBJECTIVE.  Although  the  objective of the Trust is to provide high
current income exempt from regular Federal and California  income tax consistent
with the preservation of capital,  there can be no assurance that this objective
will be achieved.

DIVIDEND  CONSIDERATIONS.  The income and dividends paid by the Trust are likely
to vary over time as fixed income market conditions change. Future dividends may
be higher or lower than the dividend the Trust is currently paying.

LEVERAGE.  The Trust utilizes leverage through  preferred stock,  which involves
special risks. The Trust's net asset value and market value may be more volatile
due to its use of leverage.

MARKET PRICE OF SHARES.  The shares of closed-end  investment  companies such as
the Trust trade on the American Stock  Exchange  (AMEX symbol:  RAA) and as such
are subject to supply and demand influences.  As a result, shares may trade at a
discount or a premium to their net asset value.

INVESTMENT GRADE MUNICIPAL  OBLIGATIONS.  The value of municipal debt securities
generally  varies  inversely with changes in prevailing  market  interest rates.
Depending  on the amount of call  protection  that the  securities  in the Trust
have, the Trust may be subject to certain  reinvestment risks in environments of
declining interest rates.

ILLIQUID  SECURITIES.  The Trust may  invest in  securities  that are  illiquid,
although  under current  market  conditions the Trust expects to do so to only a
limited extent. These securities involve special risks.

ANTITAKEOVER  PROVISIONS.  Certain antitakeover provisions will make a change in
the Trust's  business or management  more difficult  without the approval of the
Trust's Board of Directors and may have the effect of depriving  shareholders of
an  opportunity  to sell their shares at a premium above the  prevailing  market
price.

        THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC.
                                    GLOSSARY
- --------------------------------------------------------------------------------

CLOSED-END FUND:        Investment vehicle which initially offers a fixed number
                        of  shares  and  trades  on a stock  exchange.  The fund
                        invests in a portfolio of securities in accordance  with
                        its stated investment objectives and policies.

DISCOUNT:               When a fund's net asset value is greater  than its stock
                        price the fund is said to be trading at a discount.

DIVIDEND:               Income  generated  by  securities  in  a  portfolio  and
                        distributed  to  shareholders  after  the  deduction  of
                        expenses.  This Trust  declares  and pays  dividends  to
                        common shareholders on a monthly basis.

DIVIDEND REINVESTMENT:  Shareholders may have all dividends and distributions of
                        capital gains  automatically  reinvested into additional
                        shares of the Trust.

MARKET PRICE:           Price per share of a security  trading in the  secondary
                        market.  For a  closed-end  fund,  this is the  price at
                        which  one  share  of  the  fund  trades  on  the  stock
                        exchange.  If you were to buy or sell shares,  you would
                        pay or receive the market price.

NET ASSET VALUE (NAV):  Net  asset  value  is  the  total  market  value  of all
                        securities  and other  assets  held by the  Trust,  plus
                        income accrued on its investments, minus any liabilities
                        including accrued expenses,  divided by the total number
                        of outstanding  shares.  It is the underlying value of a
                        single  share on a given  day.  Net asset  value for the
                        Trust is calculated  weekly and published in Barron's on
                        Saturday  and THE NEW  YORK  TIMES  or THE  WALL  STREET
                        JOURNAL each Monday.

PREMIUM:                When a fund's  stock price is greater than its net asset
                        value, the fund is said to be trading at a premium.

PRE-REFUNDED BONDS:     These securities are  collateralized by U.S.  Government
                        securities  which are held in escrow and are used to pay
                        principal  and  interest  on the tax  exempt  issue  and
                        retire the bond in full at the date indicated, typically
                        at a premium to par.
