                  BLACKROCK CALIFORNIA MUNICIPAL INCOME TRUST
                       SEMI-ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISOR

--------------------------------------------------------------------------------

                                                                    May 31, 2002
Dear Shareholder:

     The  semi-annual  period ended April 30, 2002,  saw general  turmoil in the
equity markets.  However, during this time bond markets,  particularly municipal
securities,  proved to be a shelter for investors  seeking  refuge from unstable
economic conditions.  Over the period,  municipal bonds outperformed  Treasuries
returning 1.08% versus -1.88%, respectively,  as measured by the LEHMAN BROTHERS
MUNICIPAL BOND INDEX* and LEHMAN BROTHERS TREASURY INDEX.**

     During the six-month period, the bond market was not without volatility. In
the aftermath of the  September  11th  tragedy,  the Federal  Reserve Board (the
"Fed")  lowered  interest  rates four times  before the year  ended.  Since bond
prices  generally  move in the opposite  direction  from  interest  rates,  this
aggressive  action  initially sent bond yields downward and prices (and returns)
markedly higher.

     For the first quarter of 2002, issues of new municipal securities increased
by 10%,  totaling $65 billion,  setting a record for the largest  first  quarter
issuance in history. Due in part to budgetary pressures,  a slowing economy, and
municipalities' ongoing need to finance infrastructure projects, the final month
of  the  period  continued  to  see  heightened   levels  of  new  issuance  and
year-to-date  volume has now reached $87 billion. In March, fixed income markets
suffered  following  the Fed's  announcement  of a bias  shift  from  "potential
weakness" to  "neutral,"  which led the  investment  community to  anticipate an
economy  in  the  early  stages  of  recovery.   Despite  higher  than  expected
unemployment  numbers during April,  economic indicators generally concluded the
period on a more positive tone than they began. U.S. manufacturing,  as measured
by the ISM (Institute for Supply  Management)  Index,  remained at  expansionary
levels in April and the Consumer  Confidence Index has bounced from its November
low on  increasing  expectations.  However,  we remain  cautious that the strong
consumer  demand,  which has created an increasingly  optimistic  stimulus,  may
become exhausted and slow.

     Interest rate fluctuations,  such as we have seen recently can be difficult
for  investors,  especially  those who depend on fixed  income  investments  for
current income.  We encourage you to consult with your financial advisor to help
you establish a strategy that best fits your overall goals and risk tolerance.

     The  semi-annual  report  includes a summary of market  conditions over the
period, a review of the strategy  employed by your Trust's  portfolio  managers,
the Trust's  unaudited  financial  statements  and a listing of the  portfolio's
holdings.  We  encourage  you to read the  report  and we thank  you for  making
BlackRock part of your investment program.

Sincerely,

Dear Shareholder:

     We are pleased to present the first  unaudited  semi-annual  report for the
BlackRock  California  Municipal Income Trust (the "Trust") for the period ended
April 30,  2002.  We would like to take this  opportunity  to review the Trust's
stock price, 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 New York Stock  Exchange  under the symbol  "BFZ".  The
Trust's  investment  objective is to provide  current income exempt from regular
Federal and California  income taxes.  The Trust seeks to achieve this objective
by investing in  California  tax-exempt  general  obligation  and revenue  bonds
issued by city, county and state municipalities.  The Trust will invest at least
80% of its total assets in municipal  bonds that at the time of  investment  are
investment  grade  quality  (rated "AAA" to "BBB" by a major rating agency or of
equivalent  quality).  The  Trust may  invest  up to 20% of its total  assets in
municipal bonds that at the time of investment are non-investment  grade quality
(rated "BB" or "B" by a major rating agency or of equivalent quality).

     The table below  summarizes  the changes in the Trust's stock price and net
asset value:

THE FIXED INCOME MARKETS

     Economic  performance  was mixed  during the  semi-annual  period  although
increasingly  positive  economic  data  surfaced  as time  progressed.  The U.S.
economy  showed signs of a rebound on the heels of strong  consumer and military
spending,  which helped to overcome the  devastation of September  11th. The Fed
also provided further monetary stimulus by cutting interest rates two additional
times prior to year-end,  leaving the federal  funds rate at 1.75%.  This was in
addition to nine previous  interest rate  reductions by the Fed during 2001. The
Consumer  Confidence  Index  initially  reached its lowest  level in eight years
during November, but marked a steady climb during the remainder of the period as
investors readily anticipated an economic recovery. The economy continued to see
increasingly  optimistic data emerge throughout the first quarter of 2002. Gross
Domestic Product ("GDP") during the first quarter rose 5.6%, the fastest rate in
two years, and the manufacturing  sector saw substantial gains as the Purchasing
Managers  Index  indicated  expansion for the first time in 19 months.  Although
productivity  increased  8.6% during the first  quarter,  unemployment  in April
reached 6.0%. However,  the unexpectedly high unemployment number is believed to
be a result of recent legislation prompting many to apply for extended benefits.
After  surprising  growth in the first quarter of 2002, the fixed income markets
came under pressure  following the March 19th  announcement  by the Federal Open
Market  Committee  ("FOMC")  to leave  rates  steady,  citing a bias  shift from
"potential  weakness" to  "neutral."  The equity  markets did not  significantly
benefit  from  the  emergence  of the  strong  growth  indicators  as they  were
challenged by several high profile  bankruptcies.  Closing out the period, April
saw the  largest  advancement  in retail  sales in six months  and  inflationary
pressures remain relatively in check. However,  concerns regarding the corporate
environment  and  violence in the Middle East and Asia have left many  investors
apprehensive  about the markets.  Going forward,  although low inventory  levels
should  continue  to provide  support for  manufacturing  data,  concerns  exist
surrounding the long-term strength of the highly leveraged consumer.

     Following a steepening of the yield curve  throughout the majority of 2001,
yields over the period trended  higher causing the curve to flatten.  Signs of a
recovering  economy  caused  yields to rise in sympathy with  expectations  of a
higher fed funds rate by year end. The 5- to 10-year  portion of the yield curve
came  under  the most  pressure,  rising 93 and 86 basis  points,  respectively,
during the period.  Yields on 2- and 30-year maturities also suffered during the
period rising 80 and 72 basis points,  respectively.  After struggling following
the FOMC's  announcement  of a bias shift in March,  Treasuries  bounced back in
April.  April's performance was driven by economic pessimism,  which surfaced as
enthusiasm  for a rapid economic  recovery  waned amidst  tensions in the Middle
East,  cautious  corporate  earnings  announcements and government  reports of a
slower growth pattern.

                                       2



Looking  ahead,  a budget  surplus of only $78  billion and a 30% decline in tax
revenues for 2001 has caused Treasury finances to deteriorate sharply and should
result in  larger  auction  sizes.  However,  the  allowable  debt  limit set by
Congress  will  soon  be  reached,  possibly  leading  the  Treasury  to  pursue
additional methods of financing.  As of April 30, 2002, the 10-year Treasury was
yielding 5.09% versus 4.23% on October 31, 2001.

     On a tax-adjusted basis,  municipal bonds outperformed the taxable domestic
bond market for the semi-annual period ended April 30, 2002, returning 1.76% (as
measured by the LEHMAN BROTHERS  MUNICIPAL BOND INDEX at a tax bracket of 38.6%)
versus -0.01% for the LEHMAN BROTHERS AGGREGATE INDEX. Strong  institutional and
retail  demand for  municipal  bonds  allowed the sector to show  outperformance
versus  Treasuries  across the entire curve.  Demand was driven primarily by two
factors:  yields on municipal  securities remain  attractive versus  alternative
fixed income  investments,  and continued  volatility in the equity  markets led
investors to seek  diversification.  Strong  demand was met by  significant  new
issuance as the first quarter of 2002 posted a 10% increase over the same period
in 2001 and was the largest first quarter  total on record.  In April,  new bond
issuance  continued  its strong trend with a 12% increase  from a year  earlier,
bringing total year-to-date issuance to $87 billion. Similar to Treasuries,  the
municipal  yield  curve  flattened  over  the  period  as  yields  on  short  to
intermediate maturities rose more quickly than long-term rates.

     California's economy turned sluggish a year ago. Employment growth actually
stopped in July 2001 and through  November 2002, the State lost jobs. Since then
employment is experiencing small gains.  However, the unemployment rate is still
rising.  April  2002's  jobless rate was 6.1%,  significantly  higher than April
2001's 5%, indicating that even more people are seeking employment.

     California's General Fund revenues reflect the slower economy. Year to date
(April) revenues are 2.5% ($1.14 billion) below revised expectations. In May the
Governor  acknowledged  and addressed a projected  FY2003 $23 billion budget gap
(approximately 30% of revenues);  his remedies include tobacco tax increases and
motor vehicle registration fee hikes,  tobacco  securitization bond proceeds and
expenditure   cuts.  These  proposals  are  currently  being  discussed  in  the
Legislature. The State's General Fund is under additional stress due to the $6.2
billion  loan to the  Department  of Water  Resources  in 2001 to pay for  power
purchases.  The State had  expected to be  reimbursed  in FY 2002 through a bond
sale that remains stalled.

     California's  unresolved  energy issues  combined with the slowing  economy
continue to negatively  impact the State's fiscal position.  The State's ratings
were lowered to A1/A+ citing the General Fund's weakened  position;  both rating
agencies maintain a negative outlook.

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 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 high monthly  income.  At the
end of the semi-annual period, the Trust's leverage amount was approximately 39%
of total assets.

     Municipals  outperformed  Treasuries  for the period  due to strong  retail
demand despite record issuance.  The curve flattened over the period as rates at
the short end of the curve rose rapidly in anticipation of the Fed raising rates
in an economic recovery.  Rates at the long end of the curve rose moderately and
the curve  remains  steep on a historical  basis.  We continue to focus on bonds
with higher coupons as they provide the most  attractive  income stream and also
tend to have superior performance in a rising rate environment.

BLACKROCK CALIFORNIA
MUNICIPAL INCOME TRUST
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
--------------------------------------------------------------------------------

NOTE 1. ORGANIZATION & ACCOUNTING POLICIES

The BlackRock California Municipal Income Trust (the "Trust") was organized as a
Delaware   business   trust  on  March  30,  2001,   and  is   registered  as  a
non-diversified,  closed-end  management investment company under the Investment
Company Act of 1940. The Trust had no transactions  until July 16, 2001, when it
sold 8,028 common  shares for $115,001 to BlackRock  Advisors,  Inc.  Investment
operations  commenced on July 27, 2001. The Trust's  investment  objective is to
provide current income exempt from regular Federal and California  income taxes.
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 Trustees. 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  investments  may  be  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 Trustees.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME:  Securities  transactions  are
recorded on trade date.  Realized and unrealized gains and losses are calculated
on the  identified  cost basis.  The Trust also  records  interest  income on an
accrual basis and amortizes  premium and accretes discount to interest income on
securities purchased using the interest method.

SEGREGATION:  In cases in which the  Investment  Company Act of 1940, as amended
and the interpretive positions of the Securities and Exchange Commission ("SEC")
require  that the  Trust  segregate  assets in  connection  with  certain  Trust
investments  (e.g., when issued  securities,  reverse  repurchase  agreements or
futures contracts), the Trust will, consistent with certain interpretive letters
issued by the SEC,  designate on its books and records cash or other liquid debt
securities  having a  market  value at least  equal  to the  amount  that  would
otherwise be required to be physically segregated.

FEDERAL  INCOME TAXES:  It is the Trust's  intention to elect to be treated as a
regulated  investment  company under the Internal Revenue Code 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 Trustees on May 24,  2001,  non-interested  Trustees 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 Trustees.
This has the same  economic  effect as if the Trustees 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 Trustees in order to match its deferred compensation obligations.

CHANGE IN FINANCIAL  STATEMENT  CLASSIFICATION  FOR AMPS: In accordance with the
provisions  of  EITF  D-98,   "Classification   and  Measurement  of  Redeemable
Securities,"  effective for the current period,  the Trust has  reclassified its
Auction Market  Preferred Shares ("AMPS") outside of permanent equity in the Net
Assets  section  of the  Statement  of  Assets  and  Liabilities.  In  addition,
distributions  to AMPS  shareholders  are now  classified  as a component of net
assets resulting from operations

                                       11



on the statement of  operations  and changes in net assets and as a component of
the  investment  operations  in the  financial  highlights.  Prior year  amounts
presented  have been  restated to conform to this  period's  presentation.  This
change has no impact on the net assets applicable to common shares of the Trust.

NOTE 2. AGREEMENTS

The Trust has an Investment  Advisory  Agreement with BlackRock  Advisors,  Inc.
(the  "Advisor"),  a  wholly  owned  subsidiary  of  BlackRock,  Inc.  BlackRock
Financial Management, Inc., a wholly owned subsidiary of BlackRock, Inc., serves
as  sub-advisor  to the Trust.  BlackRock,  Inc. is an  indirect  majority-owned
subsidiary of PNC  Financial  Services  Group,  Inc. The  investment  management
agreement covers both investment advisory and administration services.

     The  investment  advisory  fee paid to the Advisor is  computed  weekly and
payable monthly at an annual rate of 0.60% of the Trust's average weekly managed
assets.  "Managed  assets"  means the total assets of the Trust  (including  any
assets  attributable to any preferred shares that may be outstanding)  minus the
sum of accrued liabilities (other than debt representing financial leverage).The
liquidation  preference  of the preferred  shares is not a liability.  The total
dollar  amounts paid to the Advisor by the Trust under the  Investment  Advisory
Agreement  for the six months  ended  April 30,  2002 and for the  period  ended
October 31,  2001 were  $590,934  and  $217,009,  respectively.  The Advisor has
voluntarily  agreed to waive receipt of a portion of the  investment  management
fee or other  expenses  of the Trust in the  amount of 0.25% of  average  weekly
managed assets for the first 5 years of the Trust's operations, 0.20% in year 6,
0.15% in year 7, 0.10% in year 8 and 0.05% in year 9. Pursuant to the agreement,
the Advisor waived fees of $422,096 during the six months ended April 30, 2002.

     Pursuant to the agreements,  the Advisor provides continuous supervision of
the investment  portfolio and pays the compensation of officers of the Trust who
are  affiliated  persons of the  Advisor,  occupancy  and certain  clerical  and
accounting  costs.  The Trust bears all other costs and expenses,  which include
reimbursements to the Advisor for certain  operational support services provided
to the Trust.

     Pursuant to the terms of the custody agreement, the Trust receives earnings
credits from its custodian when positive cash balances are maintained, which are
used to offset custody fees. The earnings credits for the six months ended April
30, 2002, were approximately $35,083.

NOTE 3. PORTFOLIO SECURITIES

Purchases and sales of investment securities, other than short-term investments,
for  the  six  months  ended  April  30,  2002,   aggregated   $106,830,016  and
$128,451,409, respectively.

     The Federal income tax basis of the Trust's  investments at April 30, 2002,
was  $339,711,936 and  accordingly,  net unrealized  appreciation was $8,378,086
(gross      unrealized       appreciation--$604,993,       gross      unrealized
depreciation--$8,981,079).

NOTE 4. CAPITAL

There are an  unlimited  number of $.001 par value common  shares of  beneficial
interest  authorized.  The Trust may classify or reclassify any unissued  common
shares of beneficial  interest into one or more series of preferred  shares.  Of
the  14,974,881  common shares of beneficial  interest  outstanding at April 30,
2002, the Advisor owned 8,192 shares.

     Transactions  in common shares of  beneficial  interest for the period July
27, 2001  (commencement  of investment  operations) to October 31, 2001, were as
follows:

     During the six months ended April 30, 2002,  the Trust issued 16,355 common
shares of beneficial interest under its Dividend Reinvestment Plan.

     Offering costs of $433,500 incurred in connection with the Trust's offering
of common  shares have been  charged to paid-in  capital in excess of par of the
common shares.

     On  October  5,  2001,  the  Trust  reclassified  5,278  common  shares  of
beneficial  interest and issued two series of Auction  Market  Preferred  Shares
("preferred shares") Series T7--2,639 and Series R7--2,639. The preferred shares
have a  liquidation  value of  $25,000  per share  plus any  accumulated  unpaid
dividends.  Underwriting  discounts of $1,319,500 and offering costs of $229,906
incurred in connection  with the preferred  share  offering have been charged to
paid-in capital in excess of par of the common shares.

     Dividends on Series T7 and R7 are cumulative at a rate which is reset every
7 days based on the results of an auction.  Dividend  rates ranged from 0.80% to
2.00% during the six months ended April 30, 2002.

                                       12



     The Trust may not declare  dividends or make other  distributions to 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 shares would be less than 200%.

     The preferred shares are 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  shares are 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
Declaration of Trust are not satisfied.

     The holders of preferred  shares have voting rights equal to the holders of
common shares (one vote per share) and will vote together with holders of common
shares as a single class. However, holders of preferred shares are also entitled
to elect two of the Trust's Trustees. In addition, the Investment Company Act of
1940 requires that, along with approval by shareholders  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 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 April 30,  2002,  the Board of Trustees  of the Trust  declared a
dividend of $0.0725 per common share  payable June 3, 2002, to  shareholders  of
record on May 15, 2002.

     For the period May 1, 2002  through  May 31,  2002,  dividends  declared on
preferred  shares totaled  $170,136 in aggregate for the  outstanding  preferred
shares.

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

     Pursuant to the Trust's  Dividend  Reinvestment  Plan (the "Plan"),  common
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 and  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 Plan 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 acquire shares for the participants' accounts,
depending upon the circumstances  described below, either (i) through receipt of
unissued but authorized shares from the Trust ("newly issued shares") or (ii) by
purchase  of  outstanding  shares  on the open  market,  on the New  York  Stock
Exchange or elsewhere  ("open-market  purchases").  If, on the dividend  payment
date,  the net asset value per share ("NAV") is equal to or less than the market
price per share plus  estimated  brokerage  commissions  (such  condition  being
referred to herein as "market premium"), the Plan Agent will invest the dividend
amount in newly issued shares on behalf of the participants. The number of newly
issued shares to be credited to each participant's account will be determined by
dividing the dollar amount of the dividend by the NAV on the date the shares are
issued.  However, if the NAV is less than 95% of the market price on the payment
date,  the dollar  amount of the  dividend  will be divided by 95% of the market
price on the payment date. If, on the dividend  payment date, the NAV is greater
than the  market  value per share plus  estimated  brokerage  commissions  (such
condition  being referred to herein as "market  discount"),  the Plan Agent will
invest the dividend amount in shares  acquired on behalf of the  participants in
open-market purchases.

     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.  There is no
direct service charge to participants in the Plan;  however,  the Trust reserves
the  right  to  amend  the Plan to  include  a  service  charge  payable  by the
participants.  All correspondence  concerning the Plan should be directed to the
Plan Agent at (800) 699-1BFM or 150 Royall Street, Canton, MA 02021.

                   BLACKROCK CALIFORNIA MUNICIPAL INCOME TRUST
                               INVESTMENT SUMMARY
--------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVES

The BlackRock  California  Municipal Income Trust's  investment  objective is to
provide current income exempt from regular Federal and California income taxes.

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
$238 billion of assets under management as of March 31, 2002.  BlackRock manages
assets on behalf of institutional and individual  investors  worldwide through a
variety of equity, fixed income,  liquidity and alternative investment products,
including the BLACKROCK FUNDS and BLACKROCK  PROVIDENT  INSTITUTIONAL  FUNDS. In
addition,  BlackRock  provides  risk  management  advice and  investment  system
services to a growing  number of  institutional  investors  under the  BLACKROCK
SOLUTIONS name.  Clients are served from the Company's  headquarters in New York
City, as well as offices in Boston, Edinburgh,  Hong Kong, San Francisco,  Tokyo
and Wilmington. BlackRock is a member of The PNC Financial Services Group (NYSE:
PNC), 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 are rated  below  investment  grade  (Ba/BB or B) or that are unrated but
deemed to be of comparable  quality by the Advisor.  The Trust intends to invest
primarily all of the assets in a portfolio of California Municipal  Obligations,
which include debt obligations issued by the State 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 Federal and California income taxes.

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 gradeCalifornia Municipal Obligations or other municipal bonds. As
such, 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 invest primarily in long-term bonds and expects bonds
in its portfolio to maintain an average  portfolio  maturity of 10-15 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  shares.  Preferred  shareholders  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  shareholders  and the interest earned on the  longer-term  securities
will provide higher income levels for common  shareholders in most interest rate
environments.  The Trust issued preferred Shares to leverage the portfolio.  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  common  shares  are traded on the New York  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

                                       16



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

The Trust employs leverage  primarily  through the issuance of preferred shares.
Leverage permits the Trust to borrow money at short-term rates and reinvest that
money in longer-term  assets,  which typically offer higher interest rates.  The
difference  between the cost of the borrowed  funds and the income earned on the
proceeds  that are  invested in  longer-term  assets is the benefit to the Trust
from leverage.

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 Trust in a  declining  rate  environment,  but can cause net
assets to decline  faster in a rapidly  rising  interest rate  environment.  The
Advisor's  portfolio  managers  continuously  monitor and  regularly  review the
Trust's  use of  leverage  and 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 shareholders.

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 OBJECTIVES. Although the objective of the Trust is to provide current
income that is exempt from regular  Federal and California  income taxes,  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 shares,
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 New York Stock  Exchange  (NYSE symbol:  BFZ) 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.

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.

HIGH  YIELD  RISK.  The Trust may  invest in high yield  bonds,  which  involves
additional risks,  including credit risk. The value of high yield, lower quality
bonds is affected by the  creditworthiness  of the issuers of the securities and
by general  economic and  specific  industry  conditions.  Issuers of high yield
bonds are not as strong  financially  as those with higher credit  ratings.  The
Trust's  investment in lower grade  securities  will expose the Trust to greater
risk than if the Trust owned only higher grade securities.

LLIQUID  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
Trustees and may have the effect of depriving  shareholders of an opportunity to
sell their shares at a premium above the prevailing market price.

ALTERNATIVE  MINIMUM TAX (AMT).  The Trust may invest in  securities  subject to
alternative minimum tax.

                                       17

                   BLACKROCK CALIFORNIA MUNICIPAL INCOME TRUST
                                    GLOSSARY
--------------------------------------------------------------------------------


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

DISCOUNT:               When a  Trust's  net  asset  value is  greater  than its
                        market  price  the  Trust  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  TRUST,  THIS IS THE PRICE AT
                        WHICH  ONE  SHARE  OF THE  TRUST  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, including
                        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  Trust's  market  price is  greater  than its net
                        asset  value,  the  Trust  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.
