                          REPORT OF INVESTMENT ADVISER

                                                                   July 31, 1997


Dear Trust Shareholder:

      After experiencing  higher interest rates in the face of a resilient stock
market and  stronger  economic  growth  for the first few  months of 1997,  bond
investors  were  comforted by more moderate  economic  data released  during the
second quarter which allowed the bond market to recapture some of its losses.

      Our outlook for the bond market is cautiously  optimistic.  Over the short
term, we believe that the recent rally may continue,  since  inflation  news has
been  positive  and U.S.  securities  appear  cheap  relative  to  their  global
counterparts.  Additionally,  Fed Chairman  Greenspan  appears to be comfortable
allowing the economy to expand in the absence of rising inflationary  pressures.
Thus,  we do not  foresee  another  tightening  in the  immediate  future in the
absence of a visible  inflation  shock.  However,  recent  wage  increases,  the
buoyant  stock  market and record  levels of consumer  confidence  could lead to
stronger  consumer  spending and overall  economic  growth in the third quarter.
Therefore, an uninterrupted decline in yields is by no means a certainty.

      This report  provides the Trust's  portfolio  managers an  opportunity  to
provide you with detailed market  commentary and to review the major  investment
themes of the  portfolio  over the past six  months.  We hope that you find this
report  informative  and look  forward to serving  your  financial  needs in the
future.


Sincerely,


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

Dear Shareholder:

      We are  pleased  to  present  the  semi-annual  report  for The  BlackRock
Investment  Quality Term Trust Inc.  ("the Trust") for the six months ended June
30, 1997.  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 diversified,  actively  managed  closed-end bond fund whose
shares are traded on the New York Stock  Exchange  under the symbol  "BQT".  The
Trust's  investment  objective is to return $10 per share (its initial  offering
price) to  shareholders  on or about  December  31,  2004 while  providing  high
monthly income. Although there can be no guarantee,  BlackRock is confident that
the  Trust  can  achieve  its  investment  objectives.  The  Trust  seeks  these
objectives by investing in investment grade fixed income  securities,  including
corporate debt securities,  mortgage-backed securities backed by U.S. Government
agencies  (such  as  Fannie  Mae,  Freddie  Mac  or  Ginnie  Mae),  asset-backed
securities and commercial mortgage-backed  securities. All of the Trust's assets
must be rated at least  "BBB" by  Standard  & Poor's or "Baa" by  Moody's at the
time of  purchase  or be  issued or  guaranteed  by the U.S.  Government  or its
agencies.

      The table below  summarizes the performance of the Trust's stock price and
NAV over the period:

THE FIXED INCOME MARKETS

      The strong  economic  growth  witnessed  during the fourth quarter of 1996
spilled over into the first quarter of 1997. Although inflationary measures such
as commodity,  producer and consumer prices remained  relatively  stable,  labor
markets continued to strengthen. In an effort to subdue this growth, the Federal
Reserve  raised  the  Federal  funds rate by 25 basis  points at their  March 25
policy meeting as a pre-emptive strike against inflation.

      After expanding at a blistering pace of 5.9% during the first quarter, the
U.S.  economy's  growth rate slowed in the second  quarter of 1997.  Signs of an
economic  slowdown were  prevalent in a broad range of  industrial  and consumer
indicators,  including lower factory orders,  decreased consumer  spending,  and
higher inventories.  In addition,  inflationary forces remained benign according
to  year-over-year  comparisons  for the consumer and  producer  indices.  These
indicators allowed the Federal Reserve to maintain interest rate levels at their
May 20 and July 2 policy  meetings and wait for more definite signs of inflation
before increasing interest rates.

      The market for mortgage-backed securities (MBS) significantly outperformed
the broader investment grade bond market for the six months ended June 30, 1997.
Strong  investor  demand for higher yielding  "spread  product",  which offers a
yield premium over comparable  maturity Treasury  securities,  boosted prices in
the mortgage  sector.  For the period,  the MBS market as measured by the LEHMAN
BROTHERS  MORTGAGE  INDEX posted a 3.91% total return versus the 3.11% return of
the LEHMAN  BROTHERS  AGGREGATE  INDEX.  In the  corporate  bond market,  strong
fundamentals  created  by steady  economic  growth,  low  inflation,  and rising
corporate profits drove the sector to outperform comparable maturity Treasuries.
Corporate  yields rose during March and April as interest  rates drifted  higher
and the stock market faltered. However, a benign inflationary outlook and strong
corporate earnings led to a reversal of performance in May and June.

      In seeking the  primary  investment  objective  of  returning  the initial
offering  price upon  maturity,  the Trust  continued  to  emphasize  securities
offering both attractive  yield spreads over Treasury  securities and a maturity
date  matching the Trust's  termination  date of December 31, 2004. To that end,
the Trust remained  primarily  invested in investment  grade corporate bonds and
well-structured  mortgage-backed  securities (MBS).  Over the period,  the Trust
took  advantage  of strong  performance  of  securities  which offer yield above
Treasuries and stable cash flows relative to residential mortgages.  Of note was
the   reduction  of  corporate   bonds  and   structured   mortgage   securities
(particularly  commercial  mortgage-backed  securities  and FHA Project  Loans).
These assets were largely reallocated to the residential  mortgage  pass-through
market, which provide the Trust an excellent  opportunity to enhance its overall
income earning potential.

THE BLACKROCK INVESTMENT QUALITY TERM TRUST INC.
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
================================================================================
NOTE 1. ACCOUNTING POLICIES
   The BlackRock  Investment  Quality Term Trust Inc. (the "Trust"),  a Maryland
corporation,  is a diversified,  closed-end  management  investment company. The
Trust's investment objective is to manage a portfolio of fixed income securities
that will return $10 per share to investors on or about  December 31, 2004 while
providing high monthly income. 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:  The Trust values mortgage-backed,  asset-backed and other
debt securities on the basis of current market quotations 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 dealers, market
transactions in comparable  securities,  various  relationships  observed in the
market  between  securities,  and  calculated  yield measures based on valuation
technology commonly employed in the market for such securities.  Exchange-traded
options are valued at their last sales price as of the close of options  trading
on the applicable  exchanges.  In the absence of a last sale, options are valued
at the average of the quoted bid and asked prices as of the close of business. A
futures  contract  is  valued  at the last  sale  price  as of the  close of the
commodities  exchange on which it trades  unless the Trust's  Board of Directors
determines  that such price does not reflect  its fair  value,  in which case it
will be  valued  at its  fair  value  as  determined  by the  Trust's  Board  of
Directors.  Any  securities  or other  assets  for  which  such  current  market
quotations  are not readily  available are valued at fair value as determined in
good faith under procedures established by and under the general supervision and
responsibility of the Trust's Board of Directors.

   Short-term securities which mature in 60 days or less are valued at amortized
cost,  if their  term to  maturity  from  date of  purchase  is 60 days or less.
Short-term securities with a term to maturity greater than 60 days from the date
of purchase are valued at current market quotations until maturity.

   In  connection  with  transactions  in  repurchase  agreements,  the  Trust's
custodian takes possession of the underlying collateral securities, the value of
which at least  equals  the  principal  amount  of the  repurchase  transaction,
including  accrued  interest.  To the  extent  that any  repurchase  transaction
exceeds one business day, the value of the collateral is  marked-to-market  on a
daily basis to ensure the adequacy of the collateral. If the seller defaults and
the value of the collateral declines or if bankruptcy  proceedings are commenced
with respect to the seller of the security, realization of the collateral by the
Trust may be delayed or limited. 

OPTION  SELLING/PURCHASING:  When the Trust  sells or  purchases  an option,  an
amount  equal to the  premium  received  or paid by the Trust is  recorded  as a
liability or an asset and is  subsequently  adjusted to the current market value
of the option  written or purchased.  Premiums  received or paid from writing or
purchasing  options  which  expire  unexercised  are treated by the Trust on the
expiration date as realized gains or losses.  The difference between the premium
and the  amount  paid or  received  on  effecting  a  closing  purchase  or sale
transaction, including brokerage commissions, is also treated as a realized gain
or loss. If an option is exercised, the premium paid or received is added to the
proceeds from the sale or cost of the purchase in determining  whether the Trust
has realized a gain or a loss on investment  transactions.  The Trust, as writer
of an option, may have no control over whether the underlying  securities may be
sold  (call) or  purchased  (put) and as a result  bears the  market  risk of an
unfavorable change in the price of the security underlying the written option.

   Options,  when used by the Trust,  help in  maintaining a targeted  duration.
Duration is a measure of the price  sensitivity  of a security or a portfolio to
relative changes in interest rates. For instance, a duration of "one" means that
a portfolio's or a security's price would be expected to change by approximately
one percent  with a one percent  change in interest  rates,  while a duration of
five  would  imply  that the price  would  move  approximately  five  percent in
relation to a one percent change in interest rates.

   Option  selling and  purchasing is used by the Trust to  effectively  "hedge"
positions  so that  changes in interest  rates do not change the duration of the
portfolio  unexpectedly.  In general,  the Trust uses options to hedge a long or
short  position  or an  overall  portfolio  that is longer or  shorter  than the
benchmark  security.  A call option gives the  purchaser of the option the right
(but not  obligation)  to buy, and obligates the seller to sell (when the option
is exercised), the underlying position at the exercise price at any time or at a
specified time during the option period. A put option gives the holder the right
to sell and obligates the writer to buy the underlying  position at the exercise
price at any time or at a specified time during the option  period.  Put options
can be purchased to  effectively  hedge a position or a portfolio  against price

                                       12

<PAGE>

declines  if a  portfolio  is  long.  In the same  sense,  call  options  can be
purchased to hedge a portfolio that is shorter than its benchmark  against price
changes. The Trust can also sell (or write) covered call options and put options
to hedge portfolio positions.

   The main risk that is associated with  purchasing  options is that the option
expires without being exercised.  In this case, the option expires worthless and
the premium paid for the option is considered the loss. The risk associated with
writing call options is that the Trust may forego the  opportunity  for a profit
if the  market  value of the  underlying  position  increases  and the option is
exercised. The risk in writing put options is that the Trust may incur a loss if
the  market  value  of the  underlying  position  decreases  and the  option  is
exercised.  In addition,  as with futures  contracts,  the Trust risks not being
able to enter into a closing transaction for the written option as the result of
an illiquid market.

INTEREST RATE SWAPS: In an interest rate swap, one investor pays a floating rate
of interest on a notional principal amount and receives a fixed rate of interest
on  the  same  notional  principal  amount  for  a  specified  period  of  time.
Alternatively,  an investor  may pay a fixed rate and  receive a floating  rate.
Rate swaps were conceived as  asset/liability  management tools. In more complex
swaps, the notional principal amount may decline (or amortize) over
time.

   During the term of the swap,  changes in the value of the swap are recognized
as unrealized gains or losses by "marking-to-market" to reflect the market value
of the swap. When the swap is terminated,  the Trust will record a realized gain
or loss  equal to the  difference  between  the  proceeds  from (or cost of) the
closing transaction and the Trust's basis in the contract, if any.

   The Trust is exposed to credit  loss in the event of  non-performance  by the
other party to the swap. However, the Trust does not anticipate  non-performance
by any counterparty.

   SWAP OPTIONS:  Swap options are similar to options on securities  except that
instead of selling or purchasing the right to buy or sell a security, the writer
or  purchaser of the swap option is granting or buying the right to enter into a
previously  agreed  upon  interest  rate swap  agreement  at any time before the
expiration of the option.  Premiums  received or paid from writing or purchasing
options are recorded as liabilities or assets and are  subsequently  adjusted to
the current market value of the option written or purchased.  Premiums  received
or paid from writing or purchasing  options which expire unexercised are treated
by the Trust on the expiration date as realized gains or losses.  The difference
between the  premium  and the amount  paid or  received  on  effecting a closing
purchase or sale transaction, including brokerage commission, is also treated as
a realized gain or loss. If an option is exercised, the premium paid or received
is added to the proceeds  from the sale or cost of the  purchase in  determining
whether the Trust has realized a gain or loss on investment transactions.

   The main risk that is  associated  with  purchasing  swap options is that the
swap option expires  without being  exercised.  In this case, the option expires
worthless and the premium paid for the swap option is considered  the loss.  The
main risk that is  associated  with the  writing of a swap  option is the market
risk of an unfavorable  change in the value of the interest rate swap underlying
the written swap option.

   Swap  options may be used by the Trust to manage the  duration of the Trust's
portfolio or as part of an income producing strategy  reflecting the view of the
Trust's  management  in the  direction  of  interest  rates.  FINANCIAL  FUTURES
CONTRACTS:  A futures  contract is an  agreement  between two parties to buy and
sell a financial  instrument  for a set price on a future date.  Initial  margin
deposits are made upon entering into futures contracts and can be either cash or
securities. During the period the futures contract is open, changes in the value
of  the   contract   are   recognized   as   unrealized   gains  or   losses  by
"marking-to-market" on a daily basis to reflect the market value of the contract
at the  end of  each  day's  trading.  Variation  margin  payments  are  made or
received,  depending upon whether unrealized gains or losses are incurred.  When
the contract is closed,  the Trust  records a realized gain or loss equal to the
difference  between the proceeds from (or cost of) the closing  transaction  and
the Trust's basis in the contract.

   Financial  futures  contracts,  when used by the Trust, help in maintaining a
targeted  duration.  Futures  contracts  can be sold to  effectively  shorten an
otherwise longer duration portfolio. In the same sense, futures contracts can be
purchased  to lengthen a portfolio  that is shorter  than its  duration  target.
Thus, by buying or selling futures contracts,  the Trust can effectively "hedge"
positions  so that  changes in interest  rates do not change the duration of the
portfolio unexpectedly.

   The Trust may invest in financial futures contracts primarily for the purpose
of hedging its existing portfolio  securities or securities the Trust intends to
purchase  against  fluctuations in value caused by changes in prevailing  market
interest  rates.  Should  interest  rates move  unexpectedly,  the Trust may not
achieve the  anticipated  benefits of the  financial  futures  contracts and may
realize a loss. The use of futures  transactions  involves the risk of imperfect
correlation in movements in the price of futures  contracts,  interest rates and
the  underlying  hedged  assets.  The Trust is also at risk of not being able to
enter into a closing transaction for the futures contract because of an illiquid
secondary market.  In addition,  since futures are used to shorten or lengthen a
portfolio's  duration,  there is a risk that the portfolio may have  temporarily
performed better without the hedge or that the Trust may lose the opportunity to
realize  appreciation  in the market price of the  underlying  positions.


                                       13

<PAGE>

SHORT SALES: The Trust may make short sales of securities as a method of hedging
potential  price declines in similar  securities  owned.  When the Trust makes a
short  sale,  it may  borrow  the  security  sold  short and  deliver  it to the
broker-dealer  through  which  it made  the  short  sale as  collateral  for its
obligation  to deliver the security upon  conclusion of the sale.  The Trust may
have to pay a fee to borrow the  particular  securities  and may be obligated to
pay over any payments received on such borrowed  securities.  A gain, limited to
the price at which the Trust sold the security short, or a loss, unlimited as to
dollar amount will be  recognized  upon the  termination  of a short sale if the
market price is less or greater than the proceeds originally received.

SECURITIES  LENDING:  The Trust may lend its  portfolio  securities to qualified
institutions.  The loans are secured by collateral at least equal, at all times,
to the market  value of the  securities  loaned.  The Trust may bear the risk of
delay in recovery of, or even loss of rights in, the  securities  loaned  should
the borrower of the securities fail financially. The Trust receives compensation
for lending its  securities in the form of interest on the loan.  The Trust also
continues to receive interest on the securities  loaned, and any gain or loss in
the market price of the securities  loaned that may occur during the term of the
loan  will be for the  account  of the  Trust.  The  Trust  did  not  engage  in
securities  lending  during  the six  months  ended  June 30,  1997.

SECURITIES  TRANSACTIONS AND NET 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  discount  and  amortizes  premium  on
securities  purchased  using the interest  method.  Expenses are recorded on the
accrual basis which may require the use of certain estimates by management.

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  substantially all of its taxable income to shareholders.  Therefore,
no federal income tax provision is required. As part of a tax planning strategy,
the Trust  intends to retain a portion of its  taxable  income and pay an excise
tax on the undistributed amounts.

DIVIDENDS  AND  DISTRIBUTIONS:   The  Trust  declares  and  pays  dividends  and
distributions  monthly,  first from net invest-ment  income,  then from realized
short-term capital gains and other sources, if necessary.  Net long-term capital
gains,  if any,  in  excess  of loss  carryforwards  are  distributed  at  least
annually. Dividends and distributions are recorded on the ex-dividend date.

DEFERRED  ORGANIZATION  EXPENSES:  A total of $70,000 was incurred in connection
with the organization of the Trust. These costs have been deferred and are being
amortized  ratably  over a period  of  sixty  months  from  the  date the  Trust
commenced  investment  operations.

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

NOTE 2. AGREEMENTS

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

   The  investment  advisory  fee paid to the  Adviser  is  computed  weekly and
payable  monthly at an annual  rate of 0.60% of the Trust's  average  weekly net
assets.  The administration fee paid to PIFM is also computed weekly and payable
monthly  at an annual  rate of 0.12% of the  Trust's  average  weekly net assets
until  December 31, 1998,  0.10% from January 1, 1999 to December 31, 2002,  and
0.08% from January 1, 2003 to the termination or liquidation of the Trust.

Pursuant to the agreements,  the Adviser provides continuous  supervision of the
investment  portfolio and pays the  compensation of officers of the Trust.  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
and dollar rolls, for the six months ended June 30, 1997 aggregated $410,724,375
and $380,392,783, respectively.

                                       14
<PAGE>

   The Trust may invest up to 30% of its total  assets in  securities  which are
not readily  marketable,  including those which are restricted as to disposition
under securities law ("restricted securities").  At June 30, 1997, the Trust did
not hold any securities restricted as to resale.

   The Trust may from time to time  purchase  in the  secondary  market  certain
mortgage  pass-through  securities  packaged or master  serviced by PNC Mortgage
Securities Corp. (or Sears Mortgage if PNC Mortgage  Securities Corp.  succeeded
to rights and duties of Sears) or mortgage related  securities  containing loans
or mortgages  originated  by PNC Bank or its  affiliates.  It is possible  under
certain  circumstances,  PNC Mortgage  Securities  Corp. or its affiliates could
have interests  that are in conflict with the holders of these  mortgage  backed
securities,  and such holders could have rights against PNC Mortgage  Securities
Corp. or its affiliates.

   The federal income tax basis of the Trust's  investments at June 30, 1997 was
substantially the same as for financial reporting purposes and, accordingly, net
unrealized  appreciation  for federal income tax purposes was $1,629,610  (gross
unrealized appreciation-$6,834,707; gross unrealized depreciation-$5,205,097).

   For federal income tax purposes, the Trust has a capital loss carryforward at
December 31, 1996 of approximately  $13,694,100,  of which $7,412,800 expires in
2001, $2,436,800 expires in 2002 and $3,844,500 expires in 2003. Accordingly, no
capital  gains  distribution  is expected to be paid to  shareholders  until net
gains have been realized in excess of such amounts.

   During the six months ended June 30, 1997,  the Trust entered into  financial
futures contracts. Details of open contracts at June 30, 1997 are as follows:

   The trust  entered  into an  interest  rate cap  agreement  which  settled on
February 19,  1997.  Under the  agreement,  the Trust paid  $1,289,600  and will
receive from the counterparty an amount of interest  calculated as the excess of
the 3 month LIBOR over 6.0%  ("Protected  Rate") based on the notional amount of
$40 million. Where the 3 month LIBOR is equal to or less than the Protected Rate
no amount is receivable by the Trust.  The agreement  terminates  onFebruary 19,
2002. At June 30, 1997, the unrealized appreciation was $45,064.

NOTE 4. BORROWINGS

REVERSE  REPURCHASE  AGREEMENTS:  The Trust may enter  into  reverse  repurchase
agreements with qualified, third party broker-dealers as determined by and under
the  direction  of the  Trust's  Board of  Directors.  Interest  on the value of
reverse  repurchase  agreements  issued  and  outstanding  will  be  based  upon
competitive  market rates at the time of issuance.  At the time the Trust enters
into a reverse repurchase agreement, it will establish and maintain a segregated
account with the lender, the value of which at least equals the principal amount
of the reverse repurchase transactions including accrued interest.

   The average daily balance of reverse repurchase agreements outstanding during
the six months ended June 30, 1997 was approximately  $126,870,685 at a weighted
average  interest rate of  approximately  5.66%.  The maximum  amount of reverse
repurchase  agreements  outstanding  at any  month-end  during  the  period  was
$127,578,088 as of April 30, 1997 which was 20.8% of total assets.

DOLLAR  ROLLS:  The Trust may enter into  dollar  rolls in which the Trust sells
securities  for delivery in the current  month and  simultaneously  contracts to
repurchase  substantially similar (same type, coupon and maturity) securities on
a specified future date.  During the roll period the Trust forgoes principal and
interest paid on the  securities.  The Trust will be compensated by the interest
earned on the cash  proceeds  of the  initial  sale and by the lower  repurchase
price at the future date.

   The average monthly balance of dollar rolls outstanding during the six months
ended June 30, 1997 was approximately $51,637,355.  The maximum amount of dollar
rolls  outstanding  at any  month-end  during  the  year was  $71,474,688  as of
February 28, 1997,  which was 11.9% of total  assets.  NOTE 5. CAPITAL There are
200 million shares of $.01 par value common stock authorized.  Of the 36,810,639
shares outstanding at June 30, 1997, the Adviser owned 10,639 shares.


NOTE 6. DIVIDENDS

Subsequent  to June 30, 1997,  the Board of  Directors  of the Trust  declared a
dividend  from  undistributed  earnings of $0.047917  per share payable July 31,
1997 to shareholders of record on July 15, 1997.

                THE BLACKROCK INVESTMENT QUALITY TERM TRUST INC.
                           DIVIDEND REINVESTMENT PLAN
- --------------------------------------------------------------------------------

   Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"), shareholders
may elect to have all distributions of dividends and capital gains automatically
reinvested  by State  Street Bank & Trust  Company  (the "Plan  Agent") in Trust
shares  pursuant to the Plan.  Shareholders  who do not  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 custodian, 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 New York
Stock Exchange or elsewhere,  for the participants' accounts. The Trust will not
issue any new shares in connection with the Plan.

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

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

   Experience   under  the  Plan  may  indicate  that  changes  are   desirable.
Accordingly,  the Trust  reserves  the right to amend or  terminate  the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
change sent to all  shareholders of the Trust at least 90 days before the record
date  for the  dividend  or  distribution.  The  Plan  also  may be  amended  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 addresses are on the front of
this report.

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

THE TRUST'S INVESTMENT OBJECTIVE
The Trust's  investment  objective is to manage a portfolio of investment  grade
fixed  income  securities  that will  return $10 per share (the  initial  public
offering  price per share) to  investors  on or about  December  31,  2004 while
providing high monthly income.

WHO MANAGES THE TRUST?
BlackRock Financial Management, Inc. ("BlackRock") is the investment adviser for
the Trust.  BlackRock is a registered  investment adviser  specializing in fixed
income  securities.  Currently,  BlackRock manages  approximately $50 billion of
assets across the government,  mortgage,  corporate and municipal sectors. These
assets are managed on behalf of  institutional  and  individual  investors in 21
closed-end  funds  which  trade on either the New York Stock or  American  Stock
Exchanges,  several  open-end  funds  and  separate  accounts  for more than 125
clients  in the U.S.  and  overseas.  BlackRock  is a  subsidiary  of PNC  Asset
Management  Group,  Inc.  which is a division of PNC Bank,  one of the  nation's
largest banking organizations.

WHAT CAN THE TRUST INVEST IN?
The Trust may invest in all fixed income  securities  rated  investment grade or
higher ("AAA",  "AA",  "A" or "BBB").  Examples of securities in which the Trust
may invest include U.S. government and government agency securities, zero coupon
securities,  mortgage-backed securities, corporate debt securities, asset-backed
securities,  U.S.  dollar-denominated  foreign  debt  securities  and  municipal
securities. Under current market conditions,  BlackRock expects that the primary
investments of the Trust will be U.S. government  securities,  securities backed
by government  agencies (such as mortgage-backed  securities) and corporate debt
securities.

WHAT IS THE ADVISER'S INVESTMENT STRATEGY?
The Adviser will seek to meet the Trust's  investment  objective by managing the
assets of the Trust so as to return the initial  offering  price ($10 per share)
at maturity.  The Trust will implement a conservative strategy that will seek to
closely match the maturity of the assets of the portfolio with the future return
of the  initial  investment  at the end of  2004.  At the  Trust's  termination,
BlackRock expects that the value of the securities which have matured,  combined
with the value of the securities  that are sold will be sufficient to return the
initial offering price to investors.  On a continuous basis, the Trust will seek
its objective by actively managing its assets in relation to market  conditions,
interest rate changes and,  importantly,  the remaining  term to maturity of the
Trust.

In addition to seeking the return of the  initial  offering  price,  the Adviser
also seeks to provide high monthly income to investors.  The portfolio  managers
will attempt to achieve this  objective by investing in securities  that provide
competitive  income.  In  addition,  leverage  will be used (in an  amount up to
331/3% of the total assets) to enhance the income of the portfolio.  In order to
maintain  competitive  yields as the Trust approaches  maturity and depending on
market  conditions,  the Adviser will attempt to purchase  securities  with call
protection  or  maturities  as close to the Trust's  maturity  date as possible.
Securities with call protection should provide the portfolio with some degree of
protection against  reinvestment risk during times of lower prevailing  interest
rates. Since the Trust's primary goal is to return the initial offering price at
maturity, any cash that the Trust receives prior to its maturity date (i.e. cash
from early and  regularly  scheduled  payments of principal  on  mortgage-backed
securities) will be reinvested in securities with maturities which coincide with
the remaining term of the Trust. Since shorter-term  securities  typically yield
less than longer-term securities,  this strategy will likely result in a decline
in the Trust's income over time. However, the Adviser will attempt to maintain a
yield which is competitive with a comparable maturity Treasury at the same point
on the yield curve (i.e.  if the Trust has three years left until its  maturity,
the  Adviser  will  attempt  to  maintain  a yield  at a  spread  over a  3-year
Treasury).  It is  important  to note that the Trust  will be  managed  so as to
preserve the integrity of the return of the initial offering price.

HOW ARE THE TRUST'S  SHARES  PURCHASED  AND SOLD?  DOES THE TRUST PAY  DIVIDENDS
REGULARLY?
The  Trust's  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 adviser. The Trust
pays monthly  dividends which are typically paid on the last business day of the
month. For shares held in the shareholder's name, dividends may be reinvested in
additional  shares of the fund through the Trust's transfer agent,  State Street
Bank & Trust Company.  Investors who wish to hold shares in a brokerage  account
should check with their financial  adviser to determine  whether their brokerage
firm offers dividend reinvestment services.

LEVERAGE CONSIDERATIONS IN A TERM TRUST
Under current  market  conditions,  leverage  increases the income earned by the
Trust.  The  Trust  employs  leverage  primarily  through  the  use  of  reverse
repurchase  agreements  and dollar rolls.  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. In general, the portfolio
is typically leveraged at approximately 331/3% of total assets.

Leverage also increases the duration (or price  volatility of the net assets) 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
rising  environment.  BlackRock'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 BlackRock consider that reduction
to be in the best interests of the shareholders.

SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO TERM TRUSTS
THE TRUST IS  INTENDED  TO BE A  LONG-TERM  INVESTMENT  AND IS NOT A  SHORT-TERM
TRADING VEHICLE.

RETURN OF INITIAL  INVESTMENT.  Although the objective of the Trust is to return
its initial offering price upon termination, there can be no assurance that this
objective will be achieved.

DIVIDEND  CONSIDERATIONS.  The income and dividends paid by the Trust are likely
to  decline  to some  extent  over the term of the Trust due to the  anticipated
shortening of the dollar-weighted average maturity of the Trust's assets.

LEVERAGE.  The Trust utilizes leverage through reverse repurchase agreements and
dollar rolls,  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 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.

MORTGAGE-BACKED   AND   ASSET-BACKED   SECURITIES.   The  cash  flow  and  yield
characteristics of these securities differ from traditional debt securities. The
major  differences  typically include more frequent payments and the possibility
of prepayments which will change the yield to maturity of the security.

CORPORATE  DEBT  SECURITIES.  The value of corporate debt  securities  generally
varies inversely with changes in prevailing market interest rates. The Trust may
be subject to certain  reinvestment  risks in environments of declining interest
rates.

ZERO COUPON SECURITIES. Such securities receive no cash flows prior to maturity,
therefore  interim  price  movements  on these  securities  are  generally  more
sensitive to interest rate movements than  securities  that make periodic coupon
payments.  These  securities  appreciate  in  value  over  time  and can play an
important role in helping the Trust achieve its primary objective.

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.

NON-U.S SECURITIES. The Trust may invest less than 10% of its assets in non-U.S.
dollar-denominated  securities  which  involve  special  risks such as currency,
political and economic risks,  although under current market conditions does not
do so.

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.

                                 mortgage   loans  or  underlying   pass-through

                                 which   the   Trust    sells    mortgage-backed
                                 securities  for  delivery in the current  month
                                 and  simultaneously   contracts  to  repurchase
                                 substantially  similar  (although not the same)
                                 securities on a specified  future date.  During

                                 principal   and   interest   payments   on  the
                                 securities,  but is  compensated  for giving up
                                 these payments by the difference in the current
                                 sales  price (for which the  security  is sold)
                                 and lower  price  that the  Trust  pays for the
                                 similar security at the end date as well as the
                                 interest  earned  on the cash  proceeds  of the

                                 outstanding  shares. It is the underlying value
                                 of a single  share on a given  day.  Net  asset
                                 value for the Trust is  calculated  weekly  and
                                 published  in BARRON'S on Saturday and THE WALL
                                 STREET JOURNAL on Monday.

                                 principal cash flows from an underlying pool of
                                 mortgage   loans  or  underlying   pass-through

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

                                 loans  and  formed  as  a  trust,  corporation,
                                 partnership,  or segregated pool of assets that
                                 elects to be treated as a REMIC for federal tax
                                 purposes.  Generally,  Fannie  Mae  REMICs  are
                                 formed   as   trusts    and   are   backed   by
                                 mortgage-backed securities.

RESIDUALS:                       Securities    issued   in    connection    with
                                 collateralized    mortgage   obligations   that
                                 generally  represent  the excess cash flow from
                                 the mortgage  assets  underlying  the CMO after
                                 payment of principal  and interest on the other
                                 CMO  securities   and  related   administrative
                                 expenses.

REVERSE REPURCHASE
AGREEMENTS:                      In a reverse  repurchase  agreement,  the Trust
                                 sells  securities and agrees to repurchase them
                                 at a mutually  agreed  date and  price.  During
                                 this time,  the Trust  continues to receive the
                                 principal  and  interest   payments  from  that
                                 security.  At the end of the  term,  the  Trust
                                 receives the same securities that were sold for
                                 the same initial dollar amount plus interest on
                                 the cash proceeds of the initial sale.

STRIPPED MORTGAGE-BACKED
SECURITIES:                      Arrangements  in  which  a pool  of  assets  is
                                 separated   into  two  classes   that   receive
                                 different   proportions  of  the  interest  and
                                 principal    distributions    from   underlying
                                 mortgage-backed  securities.  IO's and PO's are
                                 examples of strips.

                       BLACKROCK FINANCIAL MANAGMENT, INC.
                                   AN OVERVIEW
- --------------------------------------------------------------------------------


   BlackRock Financial  Management Inc.  (BlackRock) is a registered  investment
adviser which specializes in managing high quality fixed income securities, both
taxable and tax exempt. BlackRock currently manages approximately $50 billion of
assets across the government,  mortgage,  corporate and municipal sectors. These
assets are managed on behalf of  institutional  and  individual  investors in 21
closed-end  funds traded  either on the New York Stock  Exchange or the American
Stock Exchange, several open-end funds and over 125 institutional clients in the
United States and overseas.

   BlackRock was formed in April 1988 by fixed income  professionals  who sought
to create  an asset  management  firm  specializing  in  managing  fixed  income
securities for individuals and  institutional  investors.  The  professionals at
BlackRock have extensive experience creating, analyzing and trading a variety of
fixed income instruments,  including the most complex structured securities.  In
fact, individuals at BlackRock are responsible for many of the major innovations
in  the  mortgage-backed  and  asset-backed  securities  market,  including  the
creation of the 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
significant  emphasis  it  places on the  development  of  propriety  analytical
capabilities.  A quarter of the professionals at BlackRock work full-time in the
design,  maintenance  and use of such systems  which are otherwise not generally
available to  investors.  BlackRock's  propriety  analytical  tools are used for
evaluating,  investing in and designing  investment  strategies and portfolio of
fixed  income  securities,   including  mortgage   securities,   corporate  debt
securities or tax-exempt securities and a variety of hedging instruments.

   BlackRock has developed investment products which respond to investors' needs
and has been  responsible  for several major  innovations  in closed-end  funds.
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 AAAf rating by  Standard & Poor's,  and the first  closed-end  fund to
invest primarily in North American Government securities. BlackRock's closed-end
funds currently have dividend  reinvestment  plans which are designed to provide
an ongoing  source of demand for the stock in the  secondary  market.  BlackRock
manages a ladder  of  alternative  investment  vehicles,  with each fund  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
you may have about your  BlackRock  funds and thank you for the continued  trust
you place in our abilities.
