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



                                                                   July 31, 2000

Dear Shareholder:

      In the first half of the year, fears of an open-ended tightening policy by
the Federal Reserve peaked in May, which resulted in a subsequent  relief in the
market  as the U.S.  economy  seemed to  decelerate  significantly.  During  the
period, the Federal Reserve tightened short-term rates by 1.00% in an attempt to
engineer a "soft landing" for the U.S.  economy.  In the first six months of the
new millennium we have witnessed  unprecedented  volatility in both the Treasury
yield curve and the spread sectors.  The Treasury curve inverted  sharply in the
first quarter,  but as weak economic data emerged in the second quarter,  market
participants  embraced an economic  "soft  landing"  scenario  causing the yield
curve to steepen.  The downward revision in growth  expectations  allowed spread
sectors to rally in the month of June, but year-to-date  their performance still
trails Treasuries.

      While  fears  of a  hawkish  Federal  Reserve  and  consequent  risks of a
"hard-landing"  may not  materialize  immediately,  the risks are skewed in that
direction.  A longer period of subdued financial market performance is necessary
to  enable  the  labor  markets  to  build  up  slack,  which  is  an  important
pre-condition for the Fed to achieve its goal.

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

      Sincerely,

Dear Shareholder:

      We are  pleased  to  present  the  unaudited  semi-annual  report  for The
BlackRock  Insured  Municipal  Term Trust Inc.  ("the Trust") for the six-months
ended  June 30,  2000.  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 high 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 NAV
over the past year:

--------------------------------------------------------------------------------
  STOCK PRICE                    $10.00    $9.4375    5.96%   $10.0625   $ 9.25
--------------------------------------------------------------------------------
  NET ASSET VALUE (NAV)          $10.59     $10.60   (0.09%)  $10.61     $10.31
--------------------------------------------------------------------------------

THE FIXED INCOME MARKETS

      The dynamic expansion of the U.S. economy  continues  undaunted by Federal
Reserve Chairman Greenspan's attempt to brake the economy,  short of stalling it
into a recession. The labor markets remain tight, growth remains strong with 5%+
annualized  growth  rates  and  inflation  pressures  continue  to be  offset by
increased  productivity.  However,  the Fed remains cautious,  in their February
minutes it was noted that: "Other members  acknowledged that the Committee might
need to move more aggressively at a later meeting should imbalances  continue to
build and  inflation  expectations  clearly  begin to pick  up." At the  Federal
Reserve meeting in November, February and March the Fed raised the discount rate
by 0.25%  at each  meeting  and a 0.50%  increase  was made in May to bring  the
current discount rate to 6.50%.

      The Treasury Yield curve experienced a complex set of dynamics,  which has
inverted  the curve and may  continue  to invert  the curve for the  foreseeable
future.  The yields on the short-end of the curve  increased  sharply during the
period in response to three Federal  Reserve  increases to the discount rate and
perceived future Fed actions in the coming months.  The long-end of the curve is
reacting to the  "official"  announcement  that the  Treasury  will buy back $30
billion  of  Treasuries  with  maturities  ranging  from 10 to 30 years.  With a
decreasing supply of available  Treasuries,  a balanced budget, and an unchanged
demand for longer  maturity  Treasuries,  we would  anticipate this condition to
continue.  This condition is further augmented by Treasury auction activity,  as
they reduce the  available  bonds on the long end of the curve they  continue to
add supply in the 1-10 year range through periodic auctions. For the semi-annual
period,  the yield of the  10-year  Treasury  security  declined  from  6.44% on
December 31, 1999 to 6.03% on June 30, 2000.

      Municipal bonds  outperformed  the taxable domestic bond market during the
past six months,  returning  4.49% (as measured by the LEHMAN  MUNICIPAL  INDEX)
versus the LEHMAN AGGREGATE INDEX'S 3.98% on a pre-tax basis.  Overall, the tone
in the  market  during  the  period  was  extremely  positive  as the  result of
continued strong demand from individual/retail investors coupled with a slowdown
in new issuance. During 1999, households increased their holdings of individual


                                       2
<PAGE>


municipal  bonds  by over $40  billion  while  mutual  funds  saw net  outflows.
Offsetting the large amount of mutual fund outflows  during the first quarter of
2000 was a 22% decline in overall new  municipal  bond issuance YTD for the same
period, led by a 68% drop in refunding volume.  Refunding volume was down due to
the relatively higher interest rates  experienced  during the first half of 2000
when compared to the first half of 1999,  while new money  issuance has declined
because the strong economy has led to full coffers at most municipalities.

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 and
coupons.  Additionally,  the Trust  emphasizes  securities  whose maturity dates
match the termination date of the Trust.

      Over the year,  trading activity in the Trust remained  relatively low, as
many of the  securities  in the Trust's  portfolio  continued to trade at prices
above current cost.  As trading  activity that results in the Trust  realizing a
capital gain could require a taxable  distribution,  we continue to believe that
waiting to restructure  the portfolio in a higher  interest rate  environment is
the most prudent portfolio  management  strategy.  At present,  we are confident
that the Trust is on schedule to achieve its  primary  investment  objective  of
returning $10 per share upon  termination  and will continue to seek  investment
opportunities in the municipal market.

      During the period the Trust issued  $40,400,000  in  additional  preferred
shares.  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.  As of June 30,  2000,  the  Trust's  leverage  amount  was 38% of total
assets.

      The Board of Directors of the BlackRock  Insured Municipal Term Trust Inc.
voted to adjust the Trust's  monthly  dividend  effective with the July dividend
payable on August 1, 2000. The dividend  reduction was determined  after careful
evaluation of the current and  anticipated  level of the Trust's net  investment
income,  particularly the reduction in income associated with the increased cost
of borrowing as a result of successive  Federal Reserve rate increases.  The new
monthly dividend is $0.04792 ($0.575 annualized),  down from the current monthly
dividend of $0.05208 ($0.625).

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

NOTE 1. ORGANIZATION & ACCOUNTING POLICIES

The BlackRock Insured Municipal Term Trust Inc. (the "Trust"),  was organized in
Maryland on December 23, 1991 as a diversified, closed-end management investment
company. The Trust's investment  objective is to manage a diversified  portfolio
of high  quality  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  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 in  determining  values.  Short-term
securities  are valued at amortized  cost.  Any  securities  or other assets for
which such current  market  quotations  are not readily  available are valued at
fair value as determined in good faith under procedures established by and under
the general  supervision and  responsibility  of the Trust's Board of Directors.

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

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

DIVIDENDS  AND  DISTRIBUTIONS:   The  Trust  declares  and  pays  dividends  and
distributions to common  shareholders  monthly from net investment  income,  net
realized short-term capital gains and other sources, if necessary. Net long-term
capital  gains  if any,  in  excess  of loss  carryforwards  may be  distributed
annually.  Dividends and  distributions  are recorded on the  ex-dividend  date.
Dividends and distributions to preferred shareholders are accrued and determined
as described in Note 4.

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

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

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

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

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

                                       12

indirect  majority-owned  subsidiary of PNC Financial  Services Group,  Inc. The

Inc. (the  "Administrator"),  which is a wholly-owned  subsidiary of PaineWebber
Incorporated.

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

NOTE 3. PORTFOLIO SECURITIES

Purchases and sales of investment securities, other than short-term investments,
for the six months ended June 30, 2000 aggregated  $85,993,135 and  $39,542,404,
respectively.

     The federal  income tax basis of the Trust's  investments  at June 30, 2000
was  substantially  the  same  as  the  basis  for  financial   reporting,   and
accordingly,  net  unrealized  appreciation  for federal income tax purposes was
$23,165,157  (gross  unrealized   appreciation--$23,189,407,   gross  unrealized
depreciation--$24,250).

      For federal income tax purposes, the Trust had a capital loss carryforward
at December 31, 1999 of approximately  $325,000 of which $279,000 will expire in
2003 and $46,000 will expire in 2005.

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, 2000, the Advisor owned 10,583
shares.  As of June 30, 2000, there were 6,816 preferred  shares  outstanding as
follows: Series M7--4,216 and Series M28--2,600,  which includes 1,616 shares of
Series M7 issued on March 10, 2000.

      On March 10, 2000, the Trust reclassified 1,616 shares of common stock and
issued an additional  1,616 shares of Series M7 preferred  stock. The additional
shares  issued have  identical  rights and features of the existing M7 preferred
stock.  Estimated  offering  costs of  $310,666  and  underwriting  discount  of
$404,000  have been  charged to  paid-in  capital in excess of par of the common
shares.

      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 3.25% to 6.15% for the six months ended June
30, 2000.

      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 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

On June 30, 2000,  the Board of Directors of the Trust  declared  dividends from
undistributed  earnings of $0.04792 per common share  payable  August 1, 2000 to
shareholders of record on July 14, 2000.

      For the period July 1, 2000 through July 31, 2000,  dividends  declared on
preferred  shares  totalled  $557,798  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
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 transfer  agent,  as
dividend disbursing agent.

      The Plan Agent serves as agent for the shareholders in  administering  the
Plan.  After the Trust  declares a dividend or determines to make a capital gain
distribution,  the Plan Agent will, as agent for the  participants,  receive the
cash  payment and use it to buy Trust  shares in the open market on the New York
Stock Exchange 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 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 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 addresses are on the front of this report.

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

THE TRUST'S INVESTMENT OBJECTIVE

The BlackRock Insured Municipal Term 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  Advisors,  Inc.  (the  "Advisor")  is  an  SEC-registered  investment
advisor.  As of  June  30,  2000  the  Advisor  and  its  affiliates  (together,
"BlackRock")  managed $177 billion on behalf of taxable and  tax-exempt  clients
worldwide.  Strategies include fixed income, equity and cash and may incorporate
both domestic and international  securities.  Domestic  fixed-income  strategies
utilize  the  government,   mortgage,  corporate  and  municipal  bond  sectors.
BlackRock manages twenty-two  closed-end funds that are traded on either the New
York or American stock  exchanges,  and a $28 billion family of open-end  funds.
Blackrock  manages  over  629  accounts,  domiciled  in the  United  States  and
overseas.

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 Advisor to be of comparable credit quality (guaranteed,  escrowed, or backed
in trust).

WHAT IS THE ADVISOR'S INVESTMENT STRATEGY?

The Advisor 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 Adviser 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 Advisor
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 to  enhance  the  income  of the  portfolio.  In order to  maintain
competitive  yields as the Trust  approaches  maturity  and  depending on market
conditions, the Advisor 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.  If market
conditions such as high interest rate volatility, force a choice between current
income and risking the return of the initial  offering  price, it is likely that
the return of the initial offering price will be emphasized.

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 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 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  advisor 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.

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.  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 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.

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.

INVESTMENT GRADE MUNICIPAL  OBLIGATIONS.  The value of municipal debt securities
generally  varies  inversely with changes in prevailing  market  interest rates.
Depending  on the amount of call  protection  that the  securities  in the Trust
have, the Trust may be subject to certain  reinvestment risks in environments of
declining interest rates.

ILLIQUID  SECURITIES.  The Trust may  invest in  securities  that are  illiquid,
although  under current  market  conditions the Trust expects to do so to only a
limited extent. 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.

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

                                    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.

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, divided 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.

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 to retire the bond in full at
                              the date indicated, typically at a premium to par.
