THE BLACKROCK TARGET TERM TRUST INC.
SEMI-ANNUAL REPORT TO SHAREHOLDERS
REPORT OF INVESTMENT ADVISER
- --------------------------------------------------------------------------------

July 31, 1998

Dear Shareholder:

Domestic bonds provided investors with modest total returns during the
past six months, as interest rates generally fell. Supporting the bond market
was favorable inflation news and the belief that the Federal Reserve is unlikely
to raise short-term interest rates in the immediate future.

U.S. economic growth has slowed of late after a robust first quarter of
1998. We expect the fallout from the Asian fiscal crisis to quash any
significant rebound in U.S. growth for the remainder of the year. While we
expect that interest rates will be fairly stable in the near-term, our
longer-term outlook for the bond market remains optimistic, based on the
fundamentally favorable backdrop of low inflation, a currently high level of
real yields, and declining Treasury borrowing.

As you may know, the five investment management firms that comprised the
PNC Asset Management Group have consolidated under BlackRock, resulting in
BlackRock Inc., a $119 billion money management firm. We look forward to using
our global investment management expertise to present exciting investment
opportunities to closed-end fund shareholders in the future.

This report contains comments from your Trust's managers regarding the
markets and portfolio in addition to the Trust's financial statements and a
detailed portfolio listing. We thank you for your continued investment in the
Trust.

Sincerely,

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

Dear Shareholder:

We are pleased to present the semi-annual report for The BlackRock Target
Term Trust Inc. ("the Trust") for the six months ended June 30, 1998. We would
like to take this opportunity to review the Trust's stock price and net asset
value (NAV) performance, summarize market developments and discuss recent
portfolio management activity.

The Trust is a diversified, actively managed closed-end bond fund whose
shares are traded on the New York Stock Exchange under the symbol "BTT". The
Trust's investment objective is to return $10 per share (its initial offering
price) to shareholders on or about December 31, 2000 while providing high
current income. Although there can be no guarantee, BlackRock is confident that
the Trust can achieve its investment objectives. The Trust seeks these
objectives by investing in investment grade fixed income securities, including
corporate debt securities, mortgage-backed securities backed by U.S. Government
agencies (such as Fannie Mae, Freddie Mac or Ginnie Mae), asset-backed
securities and commercial mortgage-backed securities. All of the Trust's assets
must be rated at least "BBB" by Standard & Poor's or "Baa" by Moody's at time of
purchase or be issued or guaranteed by the U.S. Government or its agencies.

The table below summarizes the performance of the Trust's stock price and
NAV (the market value of its assets per share) over the period:

</TABLE>

THE FIXED INCOME MARKETS

After an extremely strong first quarter of 1998, U.S. economic growth
slowed during the past three months. Despite the strong economic growth of the
past year, inflation stayed surprisingly subdued. One explanation for the
absence of inflation in the U.S. economy stems from the aftermath of the Asian
financial crisis. U.S. exports to Asia have slowed, while the strength of the
dollar caused cheap Asian imports to flood the U.S. market and exert downward
price pressure on domestic goods.

Yields of U.S. Treasury securities have remained in a fairly narrow range
during the period. For example, the yield of the 10-Year Treasury posted a net
decline of 29 basis points (0.29%), beginning 1998 at 5.74% and closing on June
30, 1998 at 5.45%. The past six months represented a continuation of strong
Treasury performance, which has been due to moderating economic growth, low
inflation and a "flight to quality" from investors seeking a safe haven in U.S.
Treasury securities. Continued expectations that the Asian crisis will slow
economic growth and that the Fed will adopt an easing bias provided additional
support to the bond market. With Treasury supply waning due to a surplus in the
federal budget and an increased foreign demand for Treasuries due to their U.S.
government backing and relatively attractive yields, we anticipate a positive
environment for Treasuries for the balance of 1998.

<PAGE>

In light of declining interest rates and faster prepayment speeds during
the period, mortgages modestly underperformed the broader investment grade bond
market. As measured by the Lehman Brothers Mortgage Index, mortgages posted a
3.37% total return versus 3.92% for the Lehman Brothers Aggregate Index.
Mortgage rates fell below the critical 7% threshold for the first time since
January 1994, causing concerns that increased refinancing activity would
negatively impact the performance of mortgage securities. Accordingly, lower
coupon securities generally outperformed more prepayment-sensitive higher-coupon
issues. The financial turmoil in Asia caused a decline in perceived corporate
bond credit quality ratings and as a result corporate bonds underperformed
Treasuries during both the first and second quarters. Lower interest rates
brought a flood of new corporate supply during the first quarter of 1998,
contributing to the modest performance of corporates.

In accordance with the Trust's primary investment objective of returning
the initial offer price upon maturity, the Trust's portfolio management activity
focused on adding securities which offered both attractive yield spreads over
Treasury securities and a maturity date matching the Trust's termination date of
December 31, 2000. Additionally, the Trust has been active in reducing positions
in bonds which have maturity dates or potential cash flows after the Trust's
termination date. During the reporting period, the most significant additions
have been in the asset-backed securities (ABS) sector. Additionally, the Trust
maintained its significant weighting in investment grade corporate bonds and
well-structured mortgage securities such as commercial mortgage-backed
securities (CMBS). To finance these purchases, the Trust sold mortgage
pass-through securities, as their maturities may extend past the Trust's
termination date in a rising interest rate environment.

We look forward to managing the Trust to benefit from the opportunities
available in the fixed income markets and to meet its investment objectives. We
thank you for your investment in the BlackRock Target Term Trust Inc. Please
feel free to contact our marketing center at (800) 227-7BFM (7236) if you have
specific questions which were not addressed in this report.

THE BLACKROCK TARGET TERM TRUST INC.
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------
NOTE 1. ORGANIZATION & The BlackRock Target ACCOUNTING Term Trust Inc.
ACCOUNTING POLICIES (the "Trust"), a Maryland corporation, is a
diversified, closed-end management investment company. The investment objective
of the Trust is to manage a portfolio of investment grade fixed income
securities that will return $10 per share (the initial offering price per share)
to investors on or shortly before December 31, 2000 while providing high monthly
income. The ability of issuers of debt securities held by the Trust to meet
their obligations may be affected by economic developments in a specific
industry or region. No assurance can be given that the Trust's investment
objective will be achieved.

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

SECURITIES VALUATION: The Trust values mortgage-backed, asset-backed and other
debt securities on the basis of current market quotations provided by dealers or
pricing services approved by the Trust's Board of Directors. In determining the
value of a particular security, pricing services may use certain information
with respect to transactions in such securities, quotations from dealers, market
transactions in comparable securities, various relationships between securities
observed in the market and calculated yield measures based on valuation
technology commonly employed in the market for such securities. Exchange-traded
options are valued at their last sales price as of the close of options trading
on the applicable exchanges. In the absence of a last sale, options are valued
at the average of the quoted bid and asked prices as of the close of business. A
futures contract is valued at the last sale price as of the close of the
commodities exchange on which it trades unless the Trust's Board of Directors
determines that such price does not reflect its fair value, in which case it
will be valued at its fair value as determined by the Trust's Board of
Directors. Any securities or other assets for which such current market
quotations are not readily available are valued at fair value as determined in
good faith under procedures established by and under the general supervision and
responsibility of the Trust's Board of Directors.

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

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

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

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

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

<PAGE>

exercise price at any time or at a specified time during the option period. Put
options can be purchased to effectively hedge a position or a portfolio against
price declines if a portfolio is long. In the same sense, call options can be
purchased to hedge a portfolio that is shorter than its benchmark against price
changes. The Trust can also sell (or write) covered call options and put options
to hedge portfolio positions.

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

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

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

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

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

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

Swap options may be used by the Trust to manage the duration of the Trust's
portfolio reflecting the view of the Trust's management in the direction of
interest rates.

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

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

The Trust may invest in financial futures contracts primarily for the purpose
of hedging its existing portfolio securities or securities the Trust intends to
purchase against fluctuations in value caused by changes in prevailing market
interest rates. Should interest rates move unexpectedly, the Trust may not
achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions

<PAGE>

involves the risk of imperfect correlation in movements in the price of futures
contracts, interest rates and the underlying hedged assets. The Trust is also at
risk of not being able to enter into a closing transaction for the futures
contract because of an illiquid secondary market. In addition, since futures are
used to shorten or lengthen a portfolio's duration, there is a risk that the
portfolio may have temporarily performed better without the hedge or that the
Trust may lose the opportunity to realize appreciation in the market price of
the underlying positions.

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

SECURITY LENDING: The Trust may lend its portfolio securities to qualified
institutions. The loans are secured by collateral at least equal, at all times,
to the market value of the securities loaned. The Trust may bear the risk of
delay in recovery of, or even loss of rights in, the securities loaned should
the borrower of the securities fail financially. The Trust receives compensation
for lending its securities in the form of interest on the loan. The Trust also
continues to receive interest on the securities loaned, and any gain or loss in
the market price of the securities loaned that may occur during the term of the
loan will be for the account of the Trust.

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 discount or amortizes premium on securities
purchased using the interest method.

TAXES: It is the Trust's intention to continue to meet the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to shareholders. Therefore,
no federal income tax provision is required. As part of its tax planning
strategy, the Trust may retain a portion of its taxable income and pay an excise
tax on the undistributed amounts.

DIVIDENDS AND DISTRIBUTIONS: The Trust declares and pays dividends and
distributions monthly first from net investment income, then from 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.

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.

RECLASSIFICATION OF CAPITAL ACCOUNTS: The Trust accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants' Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect caused by
applying this statement was to decrease paid-in capital and increase
undistributed net investment income by $410,577 due to certain expenses not
being deductible for tax purposes. Net investment income, net realized gains and
net assets were not affected by this change.

NOTE 2. AGREEMENTS The Trust has an Investment Advisory Agreement with
BlackRock Financial Management, Inc. (the "Adviser"), a wholly-owned corporate
subsidiary of BlackRock Advisors, Inc., which is an indirect majority-owned
subsidiary of PNC Bank, N.A., and an Administration Agreement with Prudential
Investments Fund Management LLC ("PIFM"), an indirect, wholly-owned subsidiary
of The Prudential Insurance Co. of America.

The investment advisory fee paid to the Adviser is computed weekly and
payable monthly at an annual rate of 0.45% of the Trust's average weekly net
assets. The administration fee paid to PIFM is also computed weekly and payable
monthly at an annual rate of 0.10% of the first $500 million of the Trust's
average weekly net assets and 0.08% of any excess.

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. PIFM pays occupancy and certain clerical
and accounting costs of the Trust. The Trust bears all other costs and expenses.

NOTE 3. PORTFOLIO Purchases and sales of investment securities, other
SECURITIES than short-term investments and dollar rolls, for
the six months ended June 30, 1998 aggregated $824,346,237, and $716,286,353,
respectively.

The Trust may invest up to 40% of its total assets in securities which are
not readily marketable, including those which are restricted as to disposition
under securities law ("restricted securities"). At June 30, 1998, the Trust held
0.03% of its portfolio assets in securities restricted as to resale all of which
are illiquid securities.

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

The federal income tax basis of the Trust's investments at June 30, 1998 was
$1,360,982,726 and accordingly, net unrealized appreciation for federal income
tax purposes was $21,608,171 (gross unrealized appreciation-$29,010,351; gross
unrealized depreciation-$7,402,180).

For federal income tax purposes, the Trust had a capital loss carryforward at
December 31, 1997 of approximately
$3,290,000 which will expire at the termination of the Trust. Accordingly, no
capital gains distribution is expected to be paid to shareholders until net
gains have been realized in excess of such amount.

Details of open financial futures contracts at June 30, 1998 are as follows:

The Trust entered into two interest rate swaps. Under the first interest rate
swap, the Trust pays the fixed rate and receives the floating rate based on the
notional amount. Under the second interest rate swap, the Trust pays the
floating rate and receives the fixed rate based on the notional amount. Details

NOTE 4. BORROWINGS REVERSE REPURCHASE AGREEMENTS: The Trust may enter
into reverse repurchase agreements with qualified, third party broker-dealers as
determined by and under the direction of the Trust's Board of Directors.
Interest on the value of reverse repurchase agreements issued and outstanding
will be based upon competitive market rates at the time of issuance. At the time
the Trust enters into a reverse repurchase agreement, it will establish and
maintain a segregated account with the lender, the value of which at least
equals the principal amount of the reverse repurchase transactions including
accrued interest.

The average daily balance of reverse repurchase agreements outstanding during
the six months ended June 30, 1998 was approximately $408,545,327 at a weighted
average interest rate of approximately 5.32%. The maximum amount of reverse
repurchase agreements outstanding at any month-end during the six months ended
June 30, 1998 was $509,613,375 as of February 28, 1998 which was 35% of total
assets.

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

The Trust had no outstanding dollar rolls during the six months ended June
30, 1998.

NOTE 5. CAPITAL There are 200 million shares of $.01 par value common
stock authorized. Of the 95,460,639 shares outstanding at June 30, 1998, the
Adviser owned 10,639 shares.

NOTE 6. DIVIDENDS Subsequent to June 30, 1998, The Board of Directors
of the Trust declared a dividend from undistributed earnings of $.044792 per
share payable July 31, 1998 to shareholders of record on July 15, 1998.

THE BLACKROCK TARGET TERM TRUST INC.
DIVIDEND REINVESTMENT PLAN
- --------------------------------------------------------------------------------

Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"),
shareholders may elect to have all distributions of dividends and capital gains
automatically reinvested by State Street Bank & Trust Company (the "Plan Agent")
in Trust shares pursuant to the Plan. Shareholders who do not participate in the
Plan will receive all distributions in cash paid by check in United States
dollars mailed directly to the shareholders of record (or if the shares are held
in street or other nominee name, then to the nominee) by the custodian, as
dividend disbursing agent.

The Plan Agent serves as agent for the shareholders in administering the
Plan. After the Trust declares a dividend or determines to make a capital gain
distribution, the Plan Agent will, as agent for the participants, receive the
cash payment and use it to buy Trust shares in the open market on the New York
Stock Exchange or elsewhere, for the participants' accounts. The Trust will not
issue any new shares in connection with the Plan.

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

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

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

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

THE TRUST'S INVESTMENT OBJECTIVE
The BlackRock Target Term Trust Inc.'s investment objective is to manage a
portfolio of investment grade fixed income securities that will return $10 per
share (the initial public offering price per share) to investors on or shortly
before December 31, 2000 while providing high monthly income.

WHO MANAGES THE TRUST?
BlackRock Financial Management, Inc. ("BlackRock") is an SEC-registered
investment adviser. BlackRock and its affiliates currently manage over $119
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-one closed-end funds that are traded on either the New York or American
stock exchanges, and a $23 billion family of open-end equity and bond funds.
Current institutional clients number 334, domiciled in the United States and
overseas.

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

What is the Adviser's Investment Strategy?
The Adviser will seek to meet the Trust's investment objective by managing the
assets of the Trust so as to return the initial offering price ($10 per share)
at maturity. The Trust will implement a conservative strategy that will seek to
closely match the maturity of the assets of the portfolio with the future return
of the initial investment at the end of 2000. At the Trust's termination,
BlackRock expects that the value of the securities which have matured, combined
with the value of the securities that are sold will be sufficient to return the
initial offering price to investors. On a continuous basis, the Trust will seek
its objective by actively managing its assets in relation to market conditions,
interest rate changes and, importantly, the remaining term to maturity of the
Trust.

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

<PAGE>

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

LEVERAGE CONSIDERATIONS IN A TERM TRUST
Under current market conditions, leverage increases the income earned by the
Trust. The Trust employs leverage primarily through the use of reverse
repurchase agreements and dollar rolls. Leverage permits the Trust to borrow
money at short-term rates and reinvest that money in longer-term assets which
typically offer higher interest rates. The difference between the cost of the
borrowed funds and the income earned on the proceeds that are invested in longer
term assets is the benefit to the Trust from leverage. In general, the portfolio
is typically leveraged at approximately 331/3% of total assets.

Leverage also increases the duration (or price volatility of the net assets) of
the Trust, which can improve the performance of the fund in a declining rate
environment, but can cause net assets to decline faster than the market in a
rising environment. BlackRock's portfolio managers continuously monitor and
regularly review the Trust's use of leverage and the Trust may reduce, or
unwind, the amount of leverage employed should BlackRock consider that reduction
to be in the best interests of the shareholders.

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

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

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

LEVERAGE. The Trust utilizes leverage through reverse repurchase agreements and
dollar rolls, which involves special risks. The Trust's net asset value and
market value may be more volatile due to its use of leverage.

MARKET PRICE OF SHARES. The shares of closed-end investment companies such as
the Trust trade on the New York Stock Exchange and as such are subject to supply
and demand influences. As a result, shares may trade at a discount or a premium
to their net asset value.

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

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

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

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

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

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

formed as trusts and are backed by
mortgage-backed securities.

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

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

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

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

BlackRock Financial Management, Inc. ("BlackRock") is an SEC-registered
investment adviser. BlackRock and its affiliates currently manage over $119
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-one closed-end funds that are
traded on either the New York or American stock exchanges, and a $23 billion
family of open-end equity and bond funds. Current institutional clients number
334, 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
