THE BLACKROCK 1999 TERM TRUST INC.
ANNUAL REPORT TO SHAREHOLDERS
REPORT OF INVESTMENT ADVISER
- --------------------------------------------------------------------------------

January 31, 1998

Dear Trust Shareholder:

U.S. fixed income investors have been rewarded with solid total returns
over the past twelve months ended December 31, 1997, as low inflation despite
strong economic growth drove Treasury yields lower.

The economy has shown some signs of slowing, which BlackRock expects may
persist as recessions in the emerging Asian economies and Japan will moderate
U.S. growth. We do not see immediate signs of inflationary pressure nor do we
anticipate an imminent change in monetary policy by the Federal Reserve. Our
longer-term outlook for the bond market remains optimistic, based on the
fundamentally favorable backdrop of slower economic growth, low inflation and
declining Treasury borrowing.

There are exciting developments occurring at BlackRock that we would like
to share with you. As you may know, BlackRock was acquired by PNCBank, N.A. in
1995. In early 1998 the five investment management firms that comprise the
PNCAsset Management Group were consolidated under the BlackRock umbrella. This
will result in BlackRock Inc. becoming a $100 billion money management firm
ranking it among the 25 largest in the country. 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 detailed market and portfolio strategy commentary by
your Trust's managers in addition to the Trust's audited financial statements
and a detailed portfolio listing. We thank you for your continued investment in
the Trust and wish you a successful new year.

Sincerely,

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

Dear Shareholder:

We are pleased to present the annual report for The BlackRock 1999 Term
Trust Inc. ("the Trust") for the year ended December 31, 1997. We would like to
take this opportunity to review the Trust's stock price and net asset value
(NAV) performance, summarize market developments and discuss recent portfolio
management activity.

The Trust is a diversified, actively managed closed-end bond fund whose
shares are traded on the New York Stock Exchange under the symbol "BNN". The
Trust's investment objective is to return $10 per share (its initial offering
price) to shareholders on or about December 31, 1999 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 over the period:

THE FIXED INCOME MARKETS

The U.S. economy exhibited strong growth and low inflation during 1997,
pushing bond yields below 6% for the first time since early 1996. Fueled by
increased consumer spending and low unemployment, growth was robust. The primary
inflation indicators, consumer and producer prices, remained dormant throughout
the period and unemployment rate remained low. After increasing the Fed Funds
Rate to 5.50% in March, the Federal Reserve left the rate unchanged for the
remainder of the year, as the combination of slowing domestic growth and the
economic turmoil in Asia threatened to exert deflationary pressures on the U.S.
economy.

The positive momentum has continued into the early days of 1998 based, in
part, on the possibility of early elimination of the budget deficit and on
comments by Fed Chairman Greenspan that deflation was an issue. New home sales
recently hit a new cyclical peak, the employment picture remains very strong and
consumer confidence and spending remain high. Despite the strong growth, current
and future inflation both appear to be controlled.

The market for mortgage-backed securities (MBS) outperformed U.S.
Treasuries for the twelve months ended December 31, 1997. For the period, the
MBS market as measured by the LEHMAN BROTHERS MORTGAGE INDEX posted a 9.48%
total return versus the 9.20% return of the MERRILL LYNCH 5-7 YEAR TREASURY
INDEX. Demand for mortgage securities was largely concentrated in the first half
of 1997, when MBS decisively outperformed Treasuries due to low interest rate
volatility and relatively stable mortgage prepayment activity. However, mortgage
rates fell below the critical 7% threshold toward year-end, causing concerns
that increased refinancing activity would negatively impact the performance of
mortgage securities.

<PAGE>

A three-year trend of positive performance for investment grade corporates
ended abruptly in the fourth quarter of 1997 due to the Asian crisis. The
financial turmoil in Asia caused a decline in credit quality ratings and created
selling pressure for Asian Yankee bonds. Domestic corporate bonds fared better,
but the potential for lower corporate earnings and a large influx of new issues
into the market caused yields to rise. As a result, corporates underperformed
Treasuries in 1997 for only the second time in the past decade. With the U.S.
economy remaining firm, domestic corporate bond fundamentals remain fairly
positive. At wider spread levels, we see value in higher rated and improving
domestic credits.

We continued to focus on securities with final maturity dates (or "bullet"
maturities) that match the Trust's termination date. We believe that the Trust's
stake in bullet maturity securities, particularly corporate bonds, will aid the
Trust in reaching its target termination value of $10.00 per share while
maintaining a relatively stable dividend stream. The Trust has been a net seller
of mortgage-backed securities, whose cash flows and maturity dates can change in
response to interest rate movements. Mortgage bonds tend to prepay when interest
rates fall, which forces the bondholder to reinvest cash flows at lower yields.
Conversely, the average maturities of mortgage bonds can extend when interest
rates rise.

THE BLACKROCK 1999 TERM TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1. ACCOUNTING The BlackRock 1999 Term Trust Inc. (the "Trust"), a
POLICIES 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 public
offering price per share) to investors on or about December 31, 1999 while
providing high monthly income. The ability of issuers of debt securities held by
the Trust to meet their obligations may be affected by economic developments in
a specific industry or region. No assurance can be given that the Trust's
investment objective will be achieved.

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

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

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

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

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

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

Option selling and purchasing is used by the Trust to effectively hedge
positions so that changes in interest rates do not change the duration of the
portfolio unexpectedly. In general, the Trust uses options to hedge a long or
short position or an overall portfolio that is longer or shorter than the
benchmark security. A call option gives the purchaser of

<PAGE>

the option the right (but not obligation) to buy, and obligates the seller to
sell (when the option is exercised), the underlying position at the exercise
price at any time or at a specified time during the option period. A put option
gives the holder the right to sell and obligates the writer to buy the
underlying position at the exercise price at any time or at a specified time
during the option period. Put options can be purchased to effectively hedge a
position or a portfolio against price 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.

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

Financial futures contracts, when used by the Trust, help in maintaining a
targeted duration. Futures contracts can be sold to effectively shorten an
otherwise longer duration portfolio. In the same sense, futures contracts can be
purchased to lengthen a portfolio that is shorter than its duration target.
Thus, by buying or selling futures contracts, the Trust can effectively hedge
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 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 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 payments received on such borrowed securities. A gain, limited to
the price at which the Trust sold the secur-ity short, or a loss, unlimited as
to dollar amount, will be recognized upon the termination of a short sale if the
market price is less or greater than the proceeds originally received.

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

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 and amortizes premium on
securities purchased using the interest method.

<PAGE>

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.

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 are distributed at least
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, CapitalGain, 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 $240,397 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 PNC Asset
Management Group, Inc., the holding company for PNC's asset management
business, and an Administration Agreement with Prudential Investments
Fund Management LLC ("PIFM"), an indirect, wholly-owned subsidiary of The
Prudential Insurance Co. of America.

The investment advisory fee paid to the Adviser is computed weekly and
payable monthly at an annual rate of 0.40% 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 Trust's average weekly net assets.

Pursuant to the agreements, the Adviser provides continuous supervision of
the investment portfolio and pays the compensation of officers of the Trust who
are affiliated persons of the Adviser. 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 year ended December 31, 1997 aggregated $146,577,182 and $119,168,226
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 December 31, 1997, the Trust
did not hold any 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. It is possible under
certain circumstances PNC Mortgage Securities Corp. or its affiliates could have
interests that are in conflict with the holders of these mortgage backed
securities and such holders could have rights against PNC Mortgage Securities
Corp. or its affiliates.

The federal income tax basis of the Trust's investments at December 31, 1997
was substantially the same as the basis for financial reporting and,
accordingly, net unrealized depreciation for federal income tax purposes was
$2,319,363 (gross unrealized appreciation -- $3,336,081; gross unrealized
depreciation -- $1,016,718).

For federal income tax purposes, the Trust had a capital loss carryforward at
December 31, 1997 of approximately $6,473,000 of which $3,812,000 expires in
2001, $1,985,000 expires in 2002, $447,000 expires in 2004 and $228,000 expires
in 2005. Such carryforward is after utilization of approximately $470,000 to
offset the Trust's net taxable gains recognized in the year ended December 31,
1997. Accordingly, no capital gains distribution is expected to be paid to
shareholders until net gains have been realized in excess of such amounts.

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 transaction, including accrued
interest.

The average daily balance of reverse repurchase agreements outstanding during
the year ended December 31, 1997 was approximately $91,864,000 at a weighted
average interest rate of approximately 5.79%. The maximum amount of reverse
repurchase agreements outstanding at any month-end during the year ended
December 31, 1997 was $92,569,750 as of March 31, 1997 which was 29.2% 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 did not enter into dollar rolls during the
year ended December 31, 1997.

NOTE 5. CAPITAL There are 200 million shares of $.01 par value
common stock authorized. Of the 21,610,583 shares
outstanding at December 31, 1997, the Adviser owned 10,583 shares.

On August 19, 1996 the Trust transferred a substantial portion of its total
assets to a 100% owned regulated investment company subsidiary called BNN
Subsidiary, Inc. These consolidated financial statements include the operations
of both the Trust and its wholly-owned subsidiary, after elimination of all
intercompany transactions and balances. The subsidiary was liquidated on
December 12, 1997 and 100% of the subsidiary's assets were transferred back into
the Trust.

NOTE 6. DIVIDENDS Subsequent to December 31, 1997, The Board of

The BlackRock 1999 Term Trust Inc.:

We have audited the accompanying statement of assets and liabilities of The
BlackRock 1999 Term Trust Inc., including the portfolio of investments, as of
December 31, 1997, and the related statements of operations and of cash flows
for the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the

based on our audits.

We conducted our audits in accordance with generally accepted auditing

reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at December
31, 1997, by correspondence with the custodian and brokers; where replies were
not received from brokers, we performed other auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of The BlackRock 1999

THE BLACKROCK 1999 TERM TRUST INC.
TAX INFORMATION
- --------------------------------------------------------------------------------

We wish to advise you as to the federal tax status of dividends and
distributions paid by the Trust during its fiscal year ended December 31, 1997.
During the fiscal year ended December 31, 1997, the Trust paid dividends
of $0.37 per share from net investment income. For federal income tax purposes,
the aggregate of any dividends and short-term capital gains distributions you
received are reportable in your 1997 federal income tax return as ordinary
income. Further, we wish to advise you that your income dividends do not qualify
for the dividends received deduction.
For the purpose of preparing your 1997 annual federal income tax return,
however, you should report the amounts as reflected on the appropriate Form 1099
DIV which will be mailed to you in January 1998.

- --------------------------------------------------------------------------------
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 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 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 1999 TERM TRUST INC.
INVESTMENT SUMMARY
- --------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE
The Trust's investment objective is to manage a portfolio of investment grade
fixed income securities that will return $10 per share (the initial public
offering price per share) to investors on or about December 31, 1999 while
providing high monthly income.

WHO MANAGES THE TRUST?
BlackRock Financial Management, Inc. ("BlackRock" or the "Adviser") is the
investment adviser for the Trust. BlackRock is a registered investment adviser
specializing in fixed income securities. Currently, BlackRock manages
approximately $55 billion of assets across the government, mortgage, corporate
and municipal sectors. These assets are managed on behalf of institutional and
individual investors in 21 closed-end funds traded either on the New York Stock
Exchange or American Stock Exchange, several open-end funds and separate
accounts for more than 125 clients in the U.S. and overseas. BlackRock is a
subsidiary of PNC Asset Management Group, Inc. which is a division of PNC Bank,
one of the nation's largest banking organizations.

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

WHAT IS THE ADVISER'S INVESTMENT STRATEGY?
The Adviser will seek to meet the Trust's investment objective by managing the
assets of the Trust so as to return the initial offering price ($10 per share)
at maturity. The Trust will implement a conservative strategy that will seek to
closely match the maturity of the assets of the portfolio with the future return
of the initial investment at the end of 1999. 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 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 advisor. The Trust
pays monthly dividends which are typically paid on the last business day of the
month. For shares held in the shareholder's name, dividends may be reinvested in
additional shares of the fund through the Trust's transfer agent, State Street
Bank and Trust Co. 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 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 rate environment. BlackRock's portfolio managers continuously monitor and
regularly review the Trust's use of leverage and the Trust may reduce, or
unwind, the amount of leverage employed should BlackRock consider that reduction
to be in the best interests of the shareholders.

SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO TERM TRUSTS

THE TRUST IS INTENDED TO BE A LONG-TERM INVESTMENT AND IS NOT A SHORT-TERM
TRADING VEHICLE.

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

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

LEVERAGE. The Trust utilizes leverage through 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 cashflow 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 total 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.

BlackRock Financial Management Inc. (BlackRock) is a registered investment
adviser which specializes in managing high quality fixed income securities, both
taxable and tax exempt. BlackRock currently manages approximately $55 billion of

BlackRock was formed in April 1988 by fixed income professionals who
sought to create an asset management firm specializing in managing fixed income
securities for individuals and institutional investors. The professionals at
BlackRock have extensive experience creating, analyzing and trading a variety of
fixed income instruments, including the most complex structured securities. In
fact, individuals at BlackRock are responsible for many of the major innovations

creation of the CMO, the floating rate CMO, the senior/subordinated pass-through

BlackRock is unique among asset management and advisory firms in the
