              THE BLACKROCK INVESTMENT QUALITY MUNICIPAL TRUST INC.
                       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  unaudited  semi-annual  report  for  The
BlackRock  Investment  Quality Municipal Trust Inc. (the "Trust") for the period
ended  April 30,  2002.  We would  like to take this  opportunity  to review the
Trust's   stock  price  and  net  asset  value  (NAV)   performance,   summarize
developments in the fixed income markets and discuss recent portfolio management
activity.

     The Trust is a diversified,  actively  managed  closed-end  bond fund whose
shares are traded on the New York Stock  Exchange  under the symbol  "BKN".  The
Trust's  investment  objective is to provide high current  income that is exempt
from regular Federal income tax 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)  tax-exempt
general   obligation  and  revenue  bonds  issued  by  city,  county  and  state
municipalities throughout the United States.

     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. Looking ahead, a budget surplus of only $78 billion and a
30% decline in tax revenues for 2001 has caused Treasury finances

                                       2



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.

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 36%
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.

--------------------------------------------------------------------------------
THE BLACKROCK INVESTMENT
QUALITY MUNICIPAL TRUST INC.
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
--------------------------------------------------------------------------------

NOTE 1. ORGANIZATION & ACCOUNTING POLICIES

The  BlackRock  Investment  Quality  Municipal  Trust  Inc.  (the  "Trust")  was
organized  in  Maryland on  November  19,  1992,  as a  diversified,  closed-end
management  investment company.  The Trust's investment  objective is to provide
high current income exempt from regular  Federal income tax 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 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 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 Trust's Board of Directors.

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  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
annu-ally.  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 for the  Directors 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: As required,  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
$539,862  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 Financial  Highlights of the Trust for periods prior to
2001 have not been restated to reflect this change.



     The effect of this change for the six months ended April 30,  2002,  was to
increase net investment income by $56,305;  decrease net unrealized appreciation
by  $56,039  and  increase  net  realized  losses by $266.

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

                                       14



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  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"), 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 Princeton  Administrators,
L.P. (the "Administrator"),  an indirect wholly-owned affiliate of Merrill Lynch
& Co., Inc.

     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.  "Net investment 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 the
years  ended  October  31,  2001,  2000  and  1999  were  $686,474,  $1,384,129,
$1,313,673 and  $1,364,571,  respectively.  The  administration  fee paid to the
Administrator  is also computed  weekly and payable monthly at an annual rate of
0.15% of the Trust's average weekly net investment assets,  subject to a minimum
monthly fee of $12,500.  The total dollar amounts paid to the  Administrator  by
the Trust under the Administration  Agreement for the six months ended April 30,
2002 and the  years  ended  October  31,  2001,  2000 and  1999  were  $294,203,
$593,198, $563,003 and $584,816, respectively.

     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.  The  Administrator  pays occupancy and
certain  clerical and accounting  costs of the Trust.  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 period ended April 30,
2002 were $6,318.

NOTE 3. PORTFOLIO SECURITIES

Purchases and sales of investments,  other than short-term investments,  for the
six  months  ended  April 30,  2002,  aggregated  $39,130,974  and  $31,662,300,
respectively.

     The Federal  income tax basis of the Trust's  investments at April 30, 2002
was $378,791,189,  and accordingly,  net unrealized appreciation was $17,542,727
(gross  unrealized  appreciation--$22,458,804,  gross unrealized  depreciation--
$4,916,077).

     For Federal income tax purposes,  the Trust had a capital loss carryforward
at October 31, 2001 of approximately $5,514,000 of which $312,000 will expire in
2007,  $5,068,000  will  expire  in 2008  and  $134,000  will  expire  in  2009.
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 16,707,093  common shares  outstanding at
April 30, 2002, the Advisor owned 7,205 shares. As of April 30, 2002, there were
5,862 shares of preferred  stock  outstanding as follows:  Series  T7--3,262 and
Series T28--2,600.

     Dividends on Series T7 are cumulative at a rate which is reset every 7 days
based on the results of an auction.  Dividends on Series T28 are also cumulative
at a rate  which is reset  every 28 days  based on the  results  of an  auction.
Dividend  rates ranged from 1.15% to 2.00% during the six months ended April 30,
2002.

     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 stock,  voting separately as a class would be required to
(a) adopt any plan

                                       15



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 AND DISTRIBUTIONS

Subsequent  to April 30, 2002,  the Board of  Directors of the Trust  declared a
dividend from undistributed  earnings of $0.065 per common share payable June 3,
2002, to shareholders of record on May 15, 2002.

     For the period May 1, 2002 to May 31, 2002, dividends declared on preferred
stock totaled  $185,510 in aggregate  for the two  outstanding  preferred  stock
series.

              THE BLACKROCK INVESTMENT QUALITY MUNICIPAL TRUST INC.
                           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, as agent for the  participants,  receive the
cash  payment and use it to buy Trust  shares in the open market on the New York
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 back of this report.

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

THE TRUST'S INVESTMENT OBJECTIVE

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

WHO MANAGES THE TRUST?

BlackRock 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
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 may instead be deemed to be of equivalent  credit quality by the Advisor.
Examples of the types of securities that the Trust may invest in include general
obligation bonds,  which are backed by the full taxing power of the municipality
(states,  counties and cities), and revenue bonds, which are backed by a revenue
source  associated with the issuing  municipality  or by a special tax.  Revenue
bonds  include  those that are backed by  revenues  generated  by  universities,
hospitals,  housing  developments,  utilities,  public  facilities,  toll roads,
airports, etc.

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 municipal  debt  securities  that are  diversified  both  geographically  and
according to revenue source. As such, the Advisor actively manages the assets in
relation  to market  conditions  and  interest  rate  changes.  In  seeking  the
investment  objective,  the Trust does not expect to invest more than 25% of its
total assets in municipals that are issued by the same state. 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).

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 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 the Trust's 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.

                                       19



LEVERAGE CONSIDERATIONS IN THE TRUST

The Trust employs  leverage  primarily  through the issuance of preferred stock.
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 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  OBJECTIVE.  Although  the  objective of the Trust is to provide high
current  income  exempt from  regular  Federal  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 maybe
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:  BKN) 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.

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.

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

              THE BLACKROCK 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
                         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.

                                       21

                            BLACKROCK ADVISORS, INC.
                                   AN OVERVIEW
--------------------------------------------------------------------------------

     BlackRock 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
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.

     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  are  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, some
of 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.

     In view of our  continued  desire to provide a high level of service to all
our shareholders, BlackRock maintains a toll-free number for your questions. The
number is (800) 227-7BFM (7236).  We encourage you to call us with any questions
