                       SEMI-ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISOR
--------------------------------------------------------------------------------
                                                                    May 31, 2000


Dear Shareholder:

     The Federal  Reserve  continued  to  aggressively  tighten in an attempt to
achieve its objective of a  soft-landing  for the explosive U.S.  economy.  As a
result,  the Federal  Reserve  tightened  short-term  rates by 0.75%  during the
period and raised rates by another  0.50% at the May FOMC  meeting to 6.50%.  In
the  first  four  months  of  the  new   millennium  we  have  been  witness  to
unprecedented  volatility  in both  the  Treasury  yield  curve  and the  spread
sectors.  The Treasury curve inverted  sharply as  expectations of continued Fed
tightening in the wake of an insatiable U.S.  economy,  while  anticipation of a
significant buyback at the long end of the maturity spectrum led to lower yields
on long  Treasuries.  The yield curve inversion along with the premium placed on
the  dwindling  outstanding  Treasuries  caused a dramatic  underperformance  of
spread sectors relative to the performance of the Treasury  sectors,  especially
in the 10- to 30-year part of the curve.

     At this juncture,  the general  implication for spread product is negative,
but the potential for spread widening is more limited. Most of the negatives for
high quality spread product in terms of relative  supply  differentials  between
Treasuries  and  non-Treasuries  as well as equity market  volatility  have been
priced  into  the  market.  Given  current  market  conditions,  we  maintain  a
significant  overweight in high quality  spread  product.  Treasuries  are fully
valued even  considering  the strong  technicals in the market.  While near-term
volatility is virtually  guaranteed by an active Federal  Reserve,  a successful
soft landing of the economy would ultimately result in a healthier U.S. economy.

     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.

Dear Shareholder:

     We are  pleased  to  present  the  unaudited  semi-annual  report  for  The
BlackRock New York Investment Quality Municipal Trust Inc. ("the Trust") for the
six months  ended  April 30,  2000.  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 non-diversified, actively managed closed-end bond fund whose
shares are traded on the American  Stock  Exchange  under the symbol "RNY".  The
Trust's  investment  objective is to provide high current  income that is exempt
from  regular  federal  and New York  state  income  taxes  consistent  with the
preservation of capital.  The Trust seeks to achieve this objective by investing
in  investment  grade  (rated  "AAA"  to "BBB" by a major  rating  agency  or of
equivalent  quality)  municipal debt securities  issued by local  municipalities
throughout New York.

     The table below  summarizes  the changes in the Trust's stock price and NAV
over the past six months:

                        --------------------------------------------------------
                        4/30/00     10/31/99     CHANGE       HIGH        LOW
--------------------------------------------------------------------------------
STOCK PRICE             $12.1875    $13.625     (10.55%)    $13.6875    $11.4375
--------------------------------------------------------------------------------
NET ASSET VALUE (NAV)   $14.04      $14.11       (0.50%)    $14.31      $13.76
--------------------------------------------------------------------------------

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 Reserves  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 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 rose from 6.02% on October 31, 1999 to 6.22% on
April 30, 2000.

     Municipal bonds  outperformed  the taxable  domestic bond market during the
past six months,  returning  2.63% (as measured by the LEHMAN  MUNICIPAL  INDEX)
versus the LEHMAN AGGREGATE INDEX'S 1.42% 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
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 43% decline in overall new municipal  bond issuance led by a 90% drop
in refunding  volume.  Refunding  volume was down due to the  relatively  higher
interest  rates  experienced  during the first quarter 2000 when compared to the
first quarter  1999,  while new money  issuance has declined  because the strong
economy has led to full  coffers at most  municipalities.  Currently,  municipal
bonds  across  the  entire  maturity  spectrum  are  at  their  most  attractive
relationships to their Treasury market counterparts.

     New York State  benefits  from its broad and diverse  economic base and its
substantial wealth and resources.  The State's economic rebound continues,  with
private sector employment reaching an all time high, surpassing the record level
attained in June 1989.  Employment growth was particularly strong in the service
sector with  year-over-year  gains in each  component  industry.  The March 2000
unemployment rate was 4.6%, which  historically is low but still higher than the
national level of 4.1%. Fiscally,  the State is in a better position than it has
been in many years which is confirmed by the General Fund  operating  surplus of
$1.1 billion for fiscal 1999 and  projections  for a $1.6 billion  surplus in FY
2000. The out-year fiscal  imbalance and debt reform are looming  issues,  which
will effect New York's state and local governments.

     The New York City economy  continues  to expand and payroll jobs  increased
2.6% in the first  quarter  of 2000  driving  the  City's  employment  to record
levels.  The growth in personal  income tax receipts,  the financial  industry's
growing tax payments and increasing  property taxes reflect the City's  economic
strength and produce  revenues above  budgeted  levels despite recent annual tax
cuts. The City, like the State, has made substantial  strides although  out-year
budget  gaps are  projected  with much of the  future  shortfall  attributed  to
increasing tax reductions.

THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY

     The Trust's portfolio is actively managed to diversify  exposure to various
sectors,  issuers,  revenue sources and security types.  BlackRock's  investment
strategy  emphasizes  a  relative  value  approach,  which  allows  the Trust to
capitalize  upon  changing  market  conditions  by rotating  municipal  sectors,
credits and coupons.

     Additionally, the Trust employs leverage to enhance its income by borrowing
at short-term  municipal  rates and  investing  the proceeds in longer  maturity
issues that have higher  yields.  The degree to which the Trust can benefit from
its use of leverage  may affect its ability to pay high monthly  income.  At the
end of the  semi-annual  period,  the Trust's  leverage  amount was 33% of total
assets.

     The Trust has continued its bias towards  premium  coupon  securities  over
discount priced  securities,  as premium coupons offer better price  performance
during  periods of rising  interest  rates and similar  performance to discounts
when interest rates fall.

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

NOTE 1. ORGANIZATION & ACCOUNTING POLICIES

The BlackRock New York Investment Quality Municipal Trust Inc. (the "Trust") was
organized  in  Maryland  on  April  12,  1993 as a  non-diversified,  closed-end
management  investment company.  The Trust's investment objective is to manage a
portfolio of investment  quality  securities while providing high current income
exempt from regular  federal and New York state income tax  consistent  with the
preservation  of capital.  The ability of issuers of debt securities held by the
Trust to meet their obligations may be affected by economic  developments in the
state, a specific industry or region. No assurance can be given that the Trust's
investment objective will be achieved.

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

SECURITIES VALUATION:  Municipal securities  (including  commitments to purchase
such  securities  on a  "when-issued"  basis)  are valued on the basis of prices
provided  by  dealers or  pricing  services  approved  by the  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. 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 or
disposition.

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. The Trust accretes  original issue discount or 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 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.

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 indirect  majority-owned  subsidiary of PNC Financial Services Group,
Inc. The Trust has an Administration  Agreement with Prudential Investments Fund
Management LLC ("PIFM"),  a wholly-owned  subsidiary of The Prudential Insurance
Company of America.

     The  investment  advisory  fee paid to the Advisor is  computed  weekly and
payable monthly at an annual rate of 0.35%


                                       10
<PAGE>


of the Trust's average weekly net investment assets. The administration fee paid
to PIFM 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.  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,
for the six months ended April 30, 2000  aggregated  $4,098,640 and  $2,958,242,
respectively.

      The federal income tax basis of the Trust's  investments at April 30, 2000
was  substantially   the  same  as  the  basis  for  financial   reporting  and,
accordingly,   net  unrealized   appreciation  was  $818,476  (gross  unrealized
appreciation $889,290; gross unrealized depreciation $70,814).

      For federal income tax purposes, the Trust had a capital loss carryforward
at October 31, 1999 of  approximately  $659,000 of which $448,000 will expire in
2002, $199,000 will expire in 2003 and $12,000 will expire in 2007. Accordingly,
no capital gains  distribution is expected to be paid to shareholders  until net
gains have been realized in excess of such amount.

NOTE 4. CAPITAL

There are 200 million  shares of $.01 par value  common  stock  authorized.  The
Trust may classify or reclassify any unissued shares of common stock into one or
more series of preferred  stock. Of the 1,307,093  common shares  outstanding at
April 30, 2000, the Adviser owned 7,093 shares.  As of April 30, 2000 there were
392 shares of Preferred Stock Series F7 outstanding.

      Dividends  on Series F7 are  cumulative  at a rate which is reset  every 7
days based on the results of an  auction.  Dividend  rates  ranged from 3.00% to
4.00% during the six months ended April 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

Subsequent  to April 30, 2000,  the Board of  Directors of the Trust  declared a
dividend from  undistributed  earnings of $.068125 per common share payable June
1, 2000 to shareholders of record on May 15, 2000.

     For the period May 1, 2000 to May 31, 2000, dividends declared on Preferred
Stock totaled $36,638 in aggregate for the outstanding Preferred Stock.

         THE BLACKROCK NEW YORK INVESTMENT QUALITY MUNICIPAL TRUST INC.
                           DIVIDEND REINVESTMENT PLAN
--------------------------------------------------------------------------------

     Pursuant  to  the  Trust's   Dividend   Reinvestment   Plan  (the  "Plan"),
shareholders are  automatically  enrolled 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 elect not to
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 American
Stock Exchange or elsewhere,  for the participants' accounts. The Trust will not
issue any new shares under the Plan.

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

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

     The Trust  reserves the right to amend or terminate  the Plan as applied to
any dividend or  distribution  paid  subsequent to written  notice of the change
sent to all  shareholders  of the Trust at least 90 days  before the record date
for the dividend or distribution.  The Plan also may be amended or terminated by
the Plan Agent upon at least 90 days' written notice to all  shareholders of the
Trust.  All  correspondence  concerning  the Plan should be directed to the Plan
Agent at (800) 699-1BFM. The address is on the front of this report.

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

THE TRUST'S INVESTMENT OBJECTIVE

The BlackRock New York Investment Quality Municipal Trust's investment objective
is to provide high current  income exempt from regular  federal,  state and city
income tax consistent with the preservation of capital.


WHO MANAGES THE TRUST?

BlackRock  Advisors,  Inc.  (the  "Advisor")  is  an  SEC-registered  investment
advisor.  As of March  31,  2000,  the  Advisor  and its  affiliates  (together,
"BlackRock")  managed $173 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 $29 billion family of open-end  funds.
BlackRock  manages  over  590  accounts,  domiciled  in the  United  States  and
overseas.


WHAT CAN THE TRUST INVEST IN?

Under normal  conditions,  the Trust expects to continue to manage its assets so
that at least 80% of its investments are rated at least  investment grade ("BBB"
by Standard & Poor's or "Baa" by Moody's Investor Services) and up to 20% of its
assets may instead be deemed to be of equivalent  credit quality by the Adviser.
The Trust  intends to invest  substantially  all of the assets in a portfolio of
investment grade New York Municipal Obligations,  which include debt obligations
issued by or on behalf of the State, its political  subdivisions  (including the
City),  agencies and  instrumentalities and by other qualifying issuers that pay
interest which, in the opinion of the bond counsel of the issuer, is exempt from
regular Federal,  State and City income tax. New York Municipal  Obligations may
be  issued  to  obtain  funds  for  various  public   purposes,   including  the
construction of such public facilities as airports,  bridges, highways, housing,
hospitals,  mass transportation,  schools, streets, water and sewer works. Other
public  purposes for which New York Municipal  Obligations may be issued include
the  refinancing  of  outstanding  obligations  and the  obtaining  of funds for
general  operating  expenses  and for  loans to other  public  institutions  and
facilities.


WHAT IS THE ADVISOR'S INVESTMENT STRATEGY?

The Advisor will manage the assets of the Trust in  accordance  with the Trust's
investment  objective and policies to seek to achieve its objective by investing
in investment grade New York Municipal  Obligations or other qualifying issuers.
The Advisor  actively  manages the assets in relation to market  conditions  and
interest   rate   changes.   Depending   on  yield  and   portfolio   allocation
considerations, the Advisor may choose to invest a portion of the Trust's assets
in  securities  which pay interest that is subject to AMT  (alternative  minimum
tax).  The  Trust  intends  to  emphasize  investments  in  New  York  Municipal
Obligations  with  long-term  maturities  and  expects  to  maintain  an average
portfolio  maturity of 15-20 years, but the average maturity may be shortened or
lengthened from time to time depending on market conditions.

Under current market conditions the use of leverage  increases the income earned
by the Trust.  The Trust  employs  leverage  primarily  through the  issuance of
preferred  stock.   Preferred  stockholders  will  receive  dividends  based  on
short-term rates in exchange for allowing the Trust to borrow additional assets.
These assets will be invested in longer-term assets which typically offer higher
interest  rates and the  difference  between the cost of the  dividends  paid to
preferred  stockholders  and the interest earned on the  longer-term  securities
will provide higher income levels for common  stockholders in most interest rate
environments. See "Leverage Considerations in the Trust" below.


HOW ARE THE TRUST'S SHARES PURCHASED AND SOLD? DOES THE TRUST PAY DIVIDENDS
REGULARLY?

The Trust's  shares are traded on the American  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

                                       14
<PAGE>


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 THE TRUST

Leverage  increases  the duration (or price  sensitivity  of the net assets with
respect to changes  in  interest  rates) of the  Trust,  which can  improve  the
performance  of the Trust in a  declining  rate  environment,  but can cause net
assets to decline  faster in a rapidly  rising  interest rate  environment.  The
Trust may reduce, or unwind,  the amount of leverage employed should the Advisor
consider that reduction to be in the best interests of the Trust.  The Advisor's
portfolio managers  continuously monitor and regularly review the Trust's use of
leverage  and  maintain  the  ability to unwind the  leverage  if that course is
chosen.


SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO THE TRUST

The Trust is  intended  to be a  long-term  investment  and is not a  short-term
trading vehicle.

INVESTMENT  OBJECTIVE.  Although  the  objective of the Trust is to provide high
current income exempt from regular Federal, State and City income tax consistent
with the preservation of capital,  there can be no assurance that this objective
will be achieved.

DIVIDEND  CONSIDERATIONS.  The income and dividends paid by the Trust are likely
to vary over time as fixed income market conditions change. Future dividends may
be higher or lower than the dividend the Trust is currently paying.

LEVERAGE.  The Trust utilizes  leverage through the issuance of preferred stock,
which involves  special risks.  The Trust's net asset value and market value 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 American Stock  Exchange  (AMEX symbol:  RNY) 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.

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. These securities involve special risks.

ANTITAKEOVER  PROVISIONS.  Certain antitakeover provisions will make a change in
the Trust's  business or management  more difficult  without the approval of the
Trust's Board of Directors and may have the effect of depriving  shareholders of
an  opportunity  to sell their shares at a premium above the  prevailing  market
price.

                                    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 to
                         common shareholders on a monthly basis.

Dividend Reinvestment:   Shareholders  may have all dividends and  distributions
                         of  capital   gains   automatically   reinvested   into
                         additional shares of a fund.

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

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

     BlackRock Advisors,  Inc. (the " Advisor") is an SEC-registered  investment
advisor.  As of March  31,  2000,  the  Advisor  and its  affiliates  (together,
"BlackRock")  managed $173 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.   BlackRock  manages  twenty-two
closed-end  funds  that are  traded on  either  the New York or  American  stock
exchanges,  and a $29 billion family of open-end funds.  BlackRock  manages over
590 accounts, domiciled in the United States and overseas.

     BlackRock's fixed income product was introduced in 1988 by a team of highly
seasoned  fixed  income   professionals.   These   professionals  had  extensive
experience   creating,   analyzing   and  trading  a  variety  of  fixed  income
instruments,  including the most complex structured securities. In fact, several
individuals  at BlackRock  were  responsible  for  developing  many of the major
innovations  in  the  mortgage-backed   and  asset-backed   securities  markets,
including   the  creation  of  the  first  CMO,  the  floating   rate  CMO,  the
senior/subordinated pass-through and the multi-class asset-backed security.

     BlackRock  is unique  among  asset  management  and  advisory  firms in the
emphasis it places on the  development of proprietary  analytical  capabilities.
Over one  quarter  of the  firm's  professionals  is  dedicated  to the  design,
maintenance  and use of these  systems,  which are not  otherwise  available  to
investors. BlackRock's proprietary analytical tools are used for evaluating, and
designing fixed income investment  strategies for client portfolios.  Securities
purchased include mortgages,  corporate bonds,  municipal bonds and a variety of
hedging instruments.

     BlackRock  has  developed  investment  products  that respond to investors'
needs and has been  responsible  for several  major  innovations  in  closed-end
funds. In fact,  BlackRock  introduced the first  closed-end  mortgage fund, the
first taxable and tax-exempt  closed-end funds to offer a finite term, the first
closed-end  fund to  achieve a AAA rating by  Standard  & Poor's,  and the first
closed-end  fund to invest  primarily in North American  Government  securities.
Currently,  BlackRock's closed-end funds have dividend reinvestment plans, which
are designed to provide  ongoing  demand for the stock in the secondary  market.
BlackRock  manages a wide range of  investment  vehicles,  each having  specific
investment objectives and policies.

     In view of our  continued  desire to provide a high level of service to all
our shareholders, BlackRock maintains a toll-free number for your questions. The
number is (800) 227-7BFM (7236).  We encourage you to call us with any questions
that you may have about your BlackRock  funds and we thank you for the continued
trust that you place in our abilities.
