        THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC.
                          ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISOR
--------------------------------------------------------------------------------


                                                               November 30, 2001
Dear Shareholder:

     Economic  activity  slowed  significantly  during the annual  period  ended
October  31,  2001,  continuing  the  downturn  that  began in March  2000.  The
September 11 attacks on the World Trade Center and the Pentagon accelerated this
decline.  Inflation  adjusted Gross Domestic Product (GDP) fell at a 0.4% annual
rate during the third quarter, reaffirming that the economy is officially headed
towards  recession,  which is defined as two  consecutive  quarters  of negative
growth as measured by GDP.  In  response  to the  dramatic  slowdown in the U.S.
economy,  The Federal Reserve Board aggressively lowered interest rates over the
period.  In stark  contrast to its three  interest  rate  increases in February,
March,  and May of 2000,  the  Federal  Open  Market  Committee  (FOMC)  has cut
interest rates ten times in 2001.  Year-to-date,  the FOMC has reduced  interest
rates by 4.50%,  bringing the current  Federal  Funds rate to 2.00%,  its lowest
level since September 1961.

     The  weakening  U.S.  economic  environment  and the  accompanying  Federal
Reserve  activity  have had a  positive  effect  on the  fixed  income  markets.
Virtually  all sectors of the fixed income  market,  with the  exception of high
yield,  posted  double-digit  returns over the annual  period ended  October 31,
2001. As short-term interest rates declined faster than long-term interest rates
over the period, the yield curve reached historically steep levels,  making it a
very  attractive  time for leveraged  bond funds.  Because these funds borrow at
short-term rates and invest in long-term securities,  the amount they earn grows
as the difference between short-term and long-term rates increases. Furthermore,
inflation is anticipated to decline to multi-decade  lows,  which should support
high-quality fixed income securities, especially those with longer maturities.

     The rallies in the fixed  income  markets  have  barely  offset the adverse
impact of the deteriorating equity market. For the year ending October 31, 2001,
the S&P 500 and Nasdaq  fell  25.49% and  49.39%,  respectively,  and,  while we
believe that  aggressive  monetary and fiscal  stimulus will help  stabilize the
economy, we expect growth to remain below potential for a more prolonged period.
Consumption  is  unlikely  to pick up  significantly  in the face of sizable job
cuts, the likelihood that flexible compensation (bonus, profit sharing, options)
will be sharply  lower,  and that  state and local  government  spending  may be
significantly  curtailed next year. In this  environment,  we expect a period of
prolonged lower interest rates.  Although somewhat discouraging for the American
consumer,  this low inflation/low  interest rate environment  should continue to
benefit fixed income  securities.  We expect  spread  products like high quality
corporates and mortgages to perform well relative to U.S. Treasuries.

     This  annual  report  contains  a summary of market  conditions  during the
annual  period and a review of portfolio  strategy by your  Trust's  managers in
addition  to the  Trust's  audited  financial  statements  and a listing  of the
portfolio's  holdings at October 31, 2001.  Continued thanks for your confidence
in BlackRock.  We appreciate the  opportunity to help you achieve your long-term
investment goals.

Sincerely,

Dear Shareholder:

     We are  pleased to present  the  audited  annual  report for The  BlackRock
California  Investment Quality Municipal Trust Inc. (the "Trust") for the fiscal
year ended  October 31, 2001. 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  State 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 table below  summarizes  the changes in the Trust's stock price and NAV
over the annual period ended October 31, 2001:

THE FIXED INCOME MARKETS

     Investors'  hopes for a soft landing quickly turned to fears of a recession
as the U.S. economy rapidly  deteriorated  over the year. Prior to the events of
September 11, our economic  outlook  envisioned  an extended  period of sluggish
growth, with the risk of a more severe  deterioration if consumer confidence and
spending declined by any considerable degree. Economic data prior to the attacks
suggests  that the  scenario of a more severe  contraction  may have been in the
works.  Year-over-year  industrial  production  was down,  4.8% in  August,  the
largest yearly decline since 1982. The unemployment  rate had drifted up to 4.9%
from a low of 3.9% in October of last year, and the four-week average of initial
jobless claims rose to its highest level in nearly a decade. Consumer confidence
was starting to wane, and consumer credit outstanding had begun to decline.  The
events of September 11 undoubtedly  further  weakened  consumer  sentiment.  The
Conference  Board's  consumer  confidence  index  posted its  biggest  one-month
decline  since 1990.  According  to the minutes of the October 2, 2001,  Federal
Open  Market  Committee  meeting,  "The  terrorist  attacks  have  significantly
heightened  uncertainty  in an  economy  that was  already  weak.  Business  and
household spending as a consequence are being further damped.  Nonetheless,  the
long-term prospects for productivity growth and the economy remain favorable and
should become evident once the unusual forces  restraining demand abate." During
the fiscal year ended October 31, 2001, the Federal  Reserve Board  aggressively
lowered  the  Federal  Funds  rate by a total of 4.00% to bring it to 2.50%.  On
November 6, 2001, the Federal Reserve Board announced another interest rate cut,
bringing the current Federal Funds rate to 2.00%.

     Over the  course of the  year,  the U.S.  Treasury  yield  curve  steepened
significantly as the bond market rallied in response to the slowing U.S. economy
and the  aggressive  interest rate cuts by the Federal  Reserve.  U.S.  Treasury
yields on the  short-end  of the yield curve fell  sharply from a 5.91% yield on
2-year U.S.  Treasuries  as of October 31, 2000, to a 2.42% yield on October 31,
2001, in reaction to the Federal Reserve Board cutting  short-term  rates by 4%.
During the period,  the yield on the 10-year  U.S.  Treasury  fell from 5.75% on
October 31, 2000, to 4.23% on October 31, 2001. U.S. Treasury yields continue to
fall due to further  Federal  Reserve  easing and an  anticipation  of increased
supply in order to raise capital to support programs  implemented as a result of
the tragic events that occurred on September 11, 2001. On October 31, 2001,  the
U.S.  Treasury   announced  plans  to  stop  selling  30-year  U.S.   Treasuries
maintaining  that the  government  "does not need the 30-year bond to meet [its]
current financing needs." On the news that the U.S. Treasury would discontinue a
program that issued a total of $600 billion in debt since its official inception
in 1977,  the 30-year  bond price  increased  by more than 5% and yields,  which
react inversely to changes in price, fell over 36 basis points. As a result, the
on-the-run  curve,  which  measures  yields  on newly  issued  U.S.  Treasuries,
flattened 32 basis points.


                                       2



     For the annual period ended October 31, 2001,  municipal bonds outperformed
the taxable domestic bond market on a tax-adjusted  basis,  returning 17.12% (as
measured by the Lehman  Municipal  Index at a tax  bracket of 38.6%)  versus the
Lehman  Aggregate  Index's  14.56%.  Cash  inflows  over  the  period  increased
significantly  from the previous  year due to turmoil in the equity  markets and
diversification into fixed income securities. While municipals performed in line
with spread  products (i.e.  corporates,  mortgages,  etc.) and U.S.  Treasuries
throughout  the first half of the period,  the municipal  yield curve  steepened
over the latter half of the year, and showed significant  outperformance  versus
U.S. Treasuries. Refinancing opportunities, which are expected to reach historic
levels due to falling  interest rates,  continue to drive the pace of new issues
in the municipal market.

     California's  economy turned  sluggish this past summer.  During July 2001,
employment  growth  actually  stopped  and  through  October  2001,  the State's
employment  is  actually  40,000 jobs lower than June's  peak.  Unemployment  is
beginning to rise which is now reflected in October's 5.7% jobless rate was 0.6%
higher than last June's level.

     Four  months  into the fiscal  year,  California's  General  Fund  revenues
reflect the slower economy and are 6.4% below July's budgeted numbers. The lower
than expected tax receipts reflect the slowdown in manufacturing,  construction,
technology,  international  trade,  home sales and the weakness in the financial
markets. If the economic slowdown continues at this rate,  California's  General
Fund will have a deficit in excess of $4  billion at the end of its fiscal  year
(6/30/02).  This  prospect  will  pressure  the  Legislature  to further  reduce
appropriations  and limit  expenditures  in order to close the fiscal  gap.  The
State's  General  Fund is  under  additional  stress  as the  State  loaned  the
Department of Water  Resources $6.2 billion in 2001 to pay for power  purchases.
The State  expected to be reimbursed  in 2001,  however the proposed bond issue,
which will raise the funds for repayment,  is stalled and there is a question if
the repayment will be made in this fiscal year.

     Within  California,  the San Francisco to San Jose Corridor is experiencing
the greatest economic decline.  The concentration of high technology  industries
combined  with the City of San  Francisco's  dependence  on  tourism,  which has
experienced significant weakness since September 11, have severely impacted this
area.

     California's  unresolved energy issues continue to negatively influence its
economy and directly impact the fiscal position.  During November 2001,  Moody's
lowered the State's  rating to A1 from Aa3 citing the  General  Fund's  weakened
position.  California is rated A+ by Standard and Poor's; both agencies maintain
a negative outlook on this rating.


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 via auction rate preferred shares
to enhance its income by borrowing at short-term  municipal  rates and investing
the proceeds in longer  maturity  issues that have higher yields.  The degree to
which the Trust can benefit  from its use of leverage  may affect its ability to
pay monthly  income.  At the end of the annual period  (October 31,  2001),  the
Trust's leverage amount was approximately 33% of total assets.

     Municipals outperformed most spread products on a tax-adjusted basis during
the period, except on the short-end of the yield curve. The curve steepened over
most of the period and the 5 to 15 year part of the curve  remains very steep on
a historical  basis.  We remain  overweight in premium  coupon  securities in an
effort to avoid potential market discount  problems.  Premium coupon  securities
offer better price  performance  during periods of falling  interest rates,  and
similar  performance to discounts  when interest  rates rise.  Retail demand has
been robust throughout the period, with record inflows into municipal bond funds
of $2.92 billion during the month of August 2001, the largest  monthly  increase
since  1994.  Year-to-date,  net  inflows  into  municipal  bond  funds is $7.98
billion.

(1)  Effective  November 1, 2000,  the Fund adopted the  provisions of the AICPA

     change had no impact on the total net  assets of the  Trust.  The effect of
     this  change  for the year  ended  October  31,  2001 was to  increase  net
     investment  income per share by $.01,  decrease net realized and unrealized
     gains  and  losses  per  share  by  $.01,  and  increase  the  ratio of net
     investment  income to  average  net assets on common  shares  from 5.61% to

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

NOTE 1. ORGANIZATION & ACCOUNTING POLICIES

The BlackRock  California  Investment 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's investment objective is to manage a
portfolio of investment  quality  securities while providing 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  dealers or  pricing  services  approved  by the  Trust's  Board of
Directors.  In determining the value of a particular security,  pricing services
may use certain  information  with respect to  transactions  in such  securities
quotations from bond dealers,  market transactions in comparable  securities and
various  relationships  between securities.  Short-term securities are valued at
amortized  cost.  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.

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  discount  or  amortizes
premium on securities purchased using the interest method.

FEDERAL  INCOME  TAXES:  It is the  Trust's  intention  to  continue to meet the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies  and to distribute  sufficient  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.

ESTIMATES: The preparation of financial statements in conformity with accounting
principles   generally  accepted  in  the  United  States  of  America  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.

DEFERRED  COMPENSATION PLAN: Under a deferred  compensation plan approved by the
Board of Directors on February 24, 2000,  non-interested  Directors may elect to
defer receipt of all or a portion of their annual compensation.

     Deferred amounts earn a return as though equivalent dollar amounts had been
invested in common shares of other  BlackRock  funds  selected by the Directors.
This has the same economic  effect as if the Directors had invested the deferred
amounts in such other BlackRock funds.

     The deferred  compensation  plan is not funded and  obligations  thereunder
represent  general unsecured claims against the general assets of the Trust. The
Trust may, however,  elect to invest in common shares of those funds selected by
the Directors in order to match its deferred compensation obligations.

NEW ACCOUNTING  POLICIES:  Effective November 1, 2000, the Trust has adopted the
provisions of the AICPA Audit and Accounting Guide for Investment Companies,  as
revised,  and began  accreting  market  discount  on debt  securities.  Prior to
November 1, 2000,  the Trust  amortized  premiums and original issue discount on
debt securities.  The cumulative  effect of this accounting policy change had no
impact on the total net assets of the Trust. This resulted in a $22,620 increase
to  undistributed  net  investment  income and a  corresponding  decrease in net
unrealized  appreciation,  based on securities  held by the Trust on October 31,
2001.  The  Statement  of Changes  in Net  Investment  Assets and the  Financial
Highlights of the Trust for prior periods have not been restated to reflect this
change.

     The  effect of this  change  for the year  ended  October  31,  2001 was to
increase net  investment  income by $5,149 and a  corresponding  decrease in net
unrealized appreciation.

                                       11



NOTE 2. AGREEMENTS

The Trust has an Investment  Advisory Agreement with BlackRock  Advisors,  Inc.,
which is a  wholly-owned  subsidiary  of  BlackRock,  Inc.,  which in turn is an
indirect,  majority-owned  subsidiary of PNC Financial  Services Group, Inc. The
Trust  has  an  Administration   Agreement  with  Prudential   Investments  Fund
Management LLC ("PIFM"), an indirect,  wholly-owned subsidiary of The Prudential
Insurance  Company of America ("The  Prudential").  Effective  November 1, 2001,
PIFM changed its name to Prudential Investments LLC.

     The  investment  advisory  fee paid to the Advisor 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 PIFM 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 Advisor provides continuous supervision of
the investment  portfolio and pays the compensation of the officers of the Trust
who are  affiliated  persons of the  Advisor.  PIFM pays  occupancy  and certain
clerical and accounting  costs of the Trust. The Trust bears all other costs and
expenses.

NOTE 3. PORTFOLIO SECURITIES

Purchases and sales of investment securities other than short-term  investments,
for  the  year  ended  October  31,  2001  aggregated   $297,660  and  $510,994,
respectively.

     The Federal income tax basis of the Trust's investments at October 31, 2001
was  $20,165,796,  and accordingly,  net and gross  unrealized  appreciation was
$2,197,631.

     For Federal income tax purposes,  the Trust had a capital loss carryforward
at  October  31,  2001 of  approximately  $756,000  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.  The
Trust may classify or reclassify any unissued shares of common stock into one or
more series of preferred  stock. Of the 1,007,093  common shares  outstanding at
October 31, 2001,  the Advisor owned 7,093 shares.  As of October 31, 2001 there
were 300 shares of preferred Stock Series W7 outstanding.

     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 1.60% to 4.19%
during the year ended October 31, 2001.

     The Trust may not declare  dividends or make other  distributions on common
shares  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,  and the  approval  of the holders of a majority of any
outstanding  preferred stock,  voting separately as a class would be required to
(a) adopt any plan of  reorganization  that would adversely affect the preferred
stock 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,  2001,  the  Board of  Directors  of the Trust
declared a dividend  from  undistributed  earnings of $0.065625 per common share
payable December 3, 2001 to shareholders of record on November 15, 2001.

     For the period November 1, 2001 to November 30, 2001, dividends declared on
preferred stock totaled $9,591 in aggregate for the outstanding preferred stock.

        THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC.
                                 TAX INFORMATION
-------------------------------------------------------------------------------

     We are required by the  Internal  Revenue Code to advise you within 60 days
of the Trust's  fiscal year end  (October 31, 2001) as to the federal tax status
of dividends you received during such fiscal year. Accordingly,  during the year
the Trust paid  Federal  tax-exempt  dividends  of  $0.7875  per share to common
shareholders and $697.18 per share to preferred shareholders.

     For purposes of preparing your annual Federal income tax return, you should
report the amounts as reflected on the  appropriate  Form 1099-DIV or substitute
1099-DIV.

-------------------------------------------------------------------------------
                           DIVIDEND REINVESTMENT PLAN
-------------------------------------------------------------------------------

     Pursuant  to  the  Trust's   Dividend   Reinvestment   Plan  (the  "Plan"),
shareholders are  automatically  enrolled to have all distributions of dividends
and capital gains reinvested by EquiServe Trust Company, N.A. (the "Plan Agent")
in Trust shares pursuant to the Plan.  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 under 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 income tax that may be payable on
such dividends or distributions.

     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 or terminated by
the Plan Agent upon at least 90 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 address is 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  current  income  exempt  from  regular  Federal  and
California income tax consistent with the preservation of capital.

WHO MANAGES THE TRUST?

BlackRock  Advisors,  Inc. (the "Advisor")  manages the Trust.  The Advisor is a
wholly-owned subsidiary of BlackRock,  Inc.  ("BlackRock"),  which is one of the
largest  publicly traded  investment  management firms in the United States with
$226 billion of assets under  management  as of  September  30, 2001.  BlackRock
manages assets on behalf of more than 3,300 institutions and 200,000 individuals
worldwide through a variety of equity,  fixed income,  liquidity and alternative
investment separate accounts and mutual funds, including the BlackRock Funds and
BlackRock Provident  Institutional  Funds. In addition,  BlackRock provides risk
management and investment  system services to institutional  investors under the
BlackRock Solutions name. Clients are served from the Company's  headquarters in
New York City, as well as offices in Wilmington,  DE, San Francisco,  Edinburgh,
Scotland,  Tokyo,  Japan,  and  Hong  Kong.  BlackRock  is a  member  of The PNC
Financial  Services  Group,  Inc.  (NYSE:  PNC), one of the largest  diversified
financial services  organizations in the United States, and is majority-owned by
PNC and by BlackRock employees.

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 at  least  investment  grade
("BBB"by Standard & Poor's or "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
Advisor.  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 ADVISOR'S INVESTMENT STRATEGY?

The Advisor 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  or  other  qualifying
issuers.  The  Advisor  actively  manages  the  assets  in  relation  to  market
conditions  and  interest  rate  changes.   Depending  on  yield  and  portfolio
allocation  considerations,  the  Advisor  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. See "Leverage Considerations in the Trust".

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

The  Trust's  common  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 first business
day of the month. For shares held in the  shareholder's  name,  dividends may be
reinvested  in  additional  shares  of the Trust  through  its  transfer  agent,
EquiServe Trust Company,  N.A.  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  than the  market in a rapidly  rising  interest  rate
environment.  The Trust may reduce,  or unwind,  the amount of leverage employed
should the Advisor  consider that  reduction to be in the best  interests of the
Trust.  The  Advisor'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 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 the issuance of 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.

                                    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:        Common  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  common
                              shares.  It is the underlying value of a single common share on a given day. Net
                              asset  value for the Trust is  calculated  weekly and  published  in Barron's on
                              Saturday and The Wall Street Journal on 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.

PREREFUNDED 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.

                                   AN OVERVIEW
-------------------------------------------------------------------------------


     BlackRock Advisors,  Inc. (the "Advisor") manages the Trust. The Advisor is
a wholly-owned subsidiary of BlackRock, Inc. ("BlackRock"),  which is one of the
largest  publicly traded  investment  management firms in the United States with
$226 billion of assets under  management  as of  September  30, 2001.  BlackRock
manages assets on behalf of more than 3,300 institutions and 200,000 individuals
worldwide through a variety of equity,  fixed income,  liquidity and alternative
investment separate accounts and mutual funds, including the BlackRock Funds and
BlackRock Provident  Institutional  Funds. In addition,  BlackRock provides risk
management and investment  system services to institutional  investors under the
BlackRock Solutions name. Clients are served from the Company's  headquarters in
New York City, as well as offices in Wilmington,  DE, San Francisco,  Edinburgh,
Scotland,  Tokyo,  Japan,  and  Hong  Kong.  BlackRock  is a  member  of The PNC
Financial Services Group (NYSE: PNC), one of the largest  diversified  financial
services organizations in the United States, and is majority-owned by PNC and by
BlackRock employees.

     BlackRock's fixed income product was introduced in 1988 by a team of highly
seasoned  fixed  income   professionals.   These   professionals  had  extensive
experience   creating,   analyzing   and  trading  a  variety  of  fixed  income
instruments,  including the most complex structured securities. In fact, several
individuals  at BlackRock  were  responsible  for  developing  many of the major
innovations  in  the  mortgage-backed   and  asset-backed   securities  markets,
including   the  creation  of  the  first  CMO,  the  floating   rate  CMO,  the
senior/subordinated pass-through and the multi-class asset-backed security.

     BlackRock  is unique  among  asset  management  and  advisory  firms in the
emphasis it places on the  development of proprietary  analytical  capabilities.
Over one  quarter  of the  firm's  professionals  is  dedicated  to the  design,
maintenance  and use of these  systems,  which are not  otherwise  available  to
investors. BlackRock's proprietary analytical tools are used for evaluating, and
designing fixed income investment  strategies for client portfolios.  Securities
purchased include mortgages,  corporate bonds,  municipal bonds and a variety of
hedging instruments.

     BlackRock  has  developed  investment  products  that respond to investors'
needs and has been  responsible  for several  major  innovations  in  closed-end
funds. In fact,  BlackRock  introduced the first  closed-end  mortgage fund, the
first taxable and tax-exempt  closed-end funds to offer a finite term, the first
closed-end  fund to  achieve a AAA rating by  Standard  & Poor's,  and the first
closed-end  fund to invest  primarily in North American  Government  securities.
Currently,  BlackRock's closed-end funds have dividend reinvestment plans, which
are designed to provide  ongoing  demand for the stock in the secondary  market.
BlackRock  manages a wide range of  investment  vehicles,  each having  specific
investment objectives and policies.
