                          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 B. Fink                    /s/Ralph L. Schlosstein

Dear Shareholder:

      We are pleased to present the semi-annual report for The BlackRock Insured
Municipal  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  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  "BMT".  The
Trust's  investment  objective  is to  manage  a  portfolio  of  municipal  debt
securities  that  will  return  $10 per share (an  amount  equal to the  Trust's
initial public offering price) to investors on or about December 31, 2010, while
providing current income exempt from regular federal income tax. The Trust seeks
to achieve this  objective by investing in high credit quality ("AAA" or insured
to "AAA") 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 over the period:

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

- --------------------------------------------------------------------------------
NET ASSET VALUE (NAV)            $10.91    $10.87     0.37%    $10.99     $10.63
================================================================================

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, 1997
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, 1997 and July 2, 1997 policy  meetings and wait for more definite  signs
of inflation before increasing interest rates.

      Short-to-intermediate    maturity   municipals   underperformed   Treasury
equivalents  during  the  first  quarter,  despite  the  historically  favorable
interest rate environment. Issuance of municipal debt declined almost 10% during
the first quarter 1997 from first  quarter 1996 due to the higher  interest rate
environment.  Municipal  bonds  performed  reasonably  well  during  the  second
quarter,  despite a strong rally in the Treasury market. With nearly $60 billion
worth of municipal issues maturing in June and July, strong investor demand came
from both individuals and institutions  seeking to reinvest their principal back
into the market.  New  municipal  deals were heavily  oversubscribed  during the
second quarter, with a manageable supply of new issues coming to the market. For
the six month  period ended June 30,  1997,  municipal  bonds as measured by the
LEHMAN BROTHERS MUNICIPAL INDEX slightly outperformed their taxable counterparts
(LEHMAN BROTHERS AGGREGATE INDEX) with a total return of 3.20% vs. 3.11%.


                                       2

      Looking forward,  a number of distractions may impede further yield spread
tightening  in the  municipal  market,  including  potential tax reforms and the
strong  rallies in the  Treasury  and stock  markets.  BlackRock  believes  that
municipals are currently trading at historically rich ratios versus  Treasuries.
We remain  focused  on shorter  maturity  securities  until the market  provides
further  guidance on the  direction  of  interest  rates,  or the  supply/demand
characteristics of the market are altered.

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.  Over the past six months, there has been relatively little
trading  activity  in the Trust,  due to price  appreciation  of a  majority  of
securities in the portfolio  above the prices at which they were bought.  A bond
sold at a gain would  result in the Trust  realizing a capital  gain,  which may
require a taxable distribution to shareholders. Since one of the Trust's primary
investment  objectives is to pay out tax-exempt  income, we believe that waiting
to restructure the portfolio in a higher  interest rate  environment is the most
prudent strategy at this time.

      The  following  chart  compares the Trust's  current and December 31, 1996
asset composition:

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


      Additionally,  the Trust employs  leverage to enhance its income by paying
the Trust's preferred  shareholders short term municipal rates and investing the
proceeds in longer maturity issues which have higher yields. The Trust's ability
to pay high monthly income may be affected by the profitability of its leverage.
The Federal  Reserve's 25 basis point  (0.25%)  increase in the Fed funds target
rate on March 25, 1997  resulted in a modest  increase in the Trust's  borrowing
costs; however, we do not believe that one increase in short term interest rates
will negatively impact the Trust's long-term income earning ability.

THE BLACKROCK INSURED MUNICIPAL TERM TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1. ACCOUNTING POLICIES

The  BlackRock  Insured  Municipal  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 investment grade fixed
income  securities  that  will  return  $10 per share to  investors  on or about
December 31, 2010 while  providing  current  income exempt from regular  Federal
income tax. The ability of issuers of debt  securities held by the Trust to meet
their obligations may be affected by economic  developments in a specific state,
industry  or  region.  No  assurance  can be given that the  Trust's  investment
objective will be achieved.

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

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

   Short-term securities which mature in 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.

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

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

DIVIDENDS  AND  DISTRIBUTIONS:   The  Trust  declares  and  pays  dividends  and
distributions to common  shareholders  monthly from net investment  income.  Net
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 generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting  period.  Actual  results could differ from those  estimates.

NOTE 2. AGREEMENTS

The  Trust  has  an  Investment  Advisory  Agreement  with  BlackRock  Financial
Management  Inc. (the  "Adviser"),  a wholly-owned  corporate  subsidiary of PNC
Asset  Management  Group,  Inc., the holding company for PNC's asset  management
businesses  and  an  Administration   Agreement  with  Mitchell  Hutchins  Asset
Management Inc. (the "Administrator"), a wholly-owned subsidiary of Paine-Webber
Incorporated.

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

   Pursuant to the agreements,  the Adviser provides  continuous  supervision of
the investment  portfolio and pays the compensation of officers of the Trust who
are  affiliated  persons of the Adviser.  The  Administrator  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 SECURITIES investment  securities,  other than short-term
investments,  for the  period  ended June 30,  1997  aggregated  $4,346,482  and
$2,675,477, respectively.

                                       12
<PAGE>

   The federal income tax basis of the Trust's  investments at June 30, 1997 was
substantially  the same as the basis for financial  reporting and,  accordingly,
net unrealized  appreciation  for federal  income tax purposes was  $35,085,614;
(gross unrealized appreciation--$35,085,614; gross unrealized depreciation--$0).

   For federal income tax purposes, the Trust had a capital loss carryforward at
December 31, 1996 of $322,809  which  expires in 2003.  Accordingly,  no capital
gain  distribution is expected to be paid to  shareholders  until net gains have
been realized in excess of such amount.

NOTE 4. CAPITAL

There are 200 million shares of $.01 par value common stock  authorized.  Of the
25,885,639 common shares  outstanding at June 30, 1997, the Adviser owned 10,639
shares.  As of June 30, 1997, there were 5,200 preferred  shares  outstanding as
follows: 2,600 shares of Series M-7 and M-28, respectively.

   The Trust may classify or reclassify any unissued shares of common stock into
one or more series of preferred stock. On April 27, 1992 the Trust  reclassified
2,600 shares of common stock and issued two series of Auction  Market  Preferred
Stock  ("Preferred  Stock")  as  follows:  Series  M7--1,300  shares  and Series
M28--1,300  shares.  The Preferred Stock has a liquidation  value of $25,000 per
share plus any accumulated but unpaid dividends.  On May 16, 1995,  shareholders
approved a proposal to split each share of the Trust's  Auction  Rate  Municipal
Preferred  Stock  into  two  shares  and  simultaneously   reduce  each  share's
liquidation  preference  from $50,000 to $25,000 plus any accumulated but unpaid
dividends. The stock split occurred on July 24, 1995.

   Dividends on Series M7 are  cumulative  at a rate which is reset every 7 days
based on the results of an auction.  Dividends on Series M28 are also cumulative
at a rate  which is reset  every 28 days  based on the  results  of an  auction.
Dividend  rates  ranged  from 2.40% to 4.19% for the six  months  ended June 30,
1997.

   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 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 June 30,  1997,  the Board of  Directors  of the  Trust  declared
dividends from undistributed  earnings of $0.05208 per common share payable July
31, 1997 to shareholders of record on July 15, 1997.

   For the period July 1, 1997  through  July 31,  1997,  dividends  declared on
preferred  shares  totalled  $378,196  in  aggregate  for  the  two  outstanding
preferred share series.

                 THE BLACKROCK INSURED MUNICIPAL 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 and 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 for the participants'  accounts.  The Trust will not issue 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 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 Trust at (800) 699-1BFM or BlackRock Financial Management,  Inc.
at (800) 227-7BFM. The addresses are on the front of this report.

                 THE BLACKROCK INSURED MUNICIPAL TERM TRUST INC.
                               INVESTMENT SUMMARY
- --------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE

The  Trust's  investment  objective  is to provide  current  income  exempt from
regular  Federal  income  tax and to return $10 per share  (the  initial  public
offering price per share) to investors on or about December 31, 2010.

WHO MANAGES THE TRUST?

BlackRock  Financial  Management,  Inc.  ("BlackRock"  or the  "Adviser") is the
investment adviser for the Trust.  BlackRock is a registered  investment adviser
specializing  in  fixed  income   securities.   Currently,   BlackRock   manages
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 N.A., one of
the nation's largest banking organizations.

WHAT CAN THE TRUST INVEST IN?

The Trust  intends  to invest  at least  80% of its  total  assets in  municipal
obligations insured as to the timely payment of both principal and interest. The
Trust  may  invest  up to  20%  of  its  total  assets  in  uninsured  municipal
obligations  which are rated Aaa by Moody's or AAA by S&P, or are  determined by
the Adviser to be of comparable credit quality (guaranteed,  escrowed, or backed
in trust).

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  2010.  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 portfolio of municipal  obligations  and
retaining a small amount of income each year.

In addition to seeking the return of the  initial  offering  price,  the Adviser
also  seeks  to  provide  current  income  exempt  from  Federal  income  tax 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 35% of 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 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.  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 and 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 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.  In general,  the portfolio is typically  leveraged at
approximately 35% 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 rate 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 the issuance of preferred stock
which involves  special risks.  The Trust's net asset value and market value may
be more volatile due to its use of leverage.

MARKET PRICE OF SHARES.  The shares of closed-end  investment  companies such as
the Trust trade on the New York Stock  Exchange  (NYSE symbol:  BMT) 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.

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. Investing in these securities involves 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.

MUNICIPAL OBLIGATIONS.  Municipal obligations include debt obligations issued by
states,  cities, and local authorities,  and possessions and certain territories
of the United States to obtain funds for various public purposes,  including the
construction of public  facilities,  the refinancing of outstanding  obligations
and the obtaining of funds for general operating expenses and for loans to other
public  institutions  and  facilities.  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.

ALTERNATIVE  MINIMUM TAX (AMT).  The Trust may invest in  securities  subject to
alternative minimum tax. The Trust currently holds no AMT securities.

                 THE BLACKROCK INSUREDMUNICIPAL TERM TRUST INC.
                                    GLOSSARY
- --------------------------------------------------------------------------------

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

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

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

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

EMBEDDED                 CAPS:  Also  known  as  additional  interest  municipal
                         bonds.  These  securities  are  intended to protect the
                         income  that the  Trust  earns  through  leverage  from
                         significant increase in short-term rates. The coupon on
                         these  bonds will  increase  if  short-term  rates rise
                         significantly.

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

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

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

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

                       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  proprietary  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  proprietary  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.
