                          ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISOR
- --------------------------------------------------------------------------------


                                                                January 31, 2000
Dear Shareholder:

      After easing  monetary  policy  three times  during the fourth  quarter of
1998,  the Federal  Reserve  reversed  its trend by raising the Fed funds target
rate 75 basis  points (to 5.50%)  over the course of 1999 in  response to robust
GDP, low  unemployment  and rising  equity  prices.  U.S.  Treasury  yields rose
significantly  during  the past  twelve  months,  with the yield of the  30-year
Treasury rising above 6.00% for the first time since May 1998.

      Despite the rise in Treasury yields,  continued strong economic growth may
spur the  Federal  Reserve to  proactively  fight  perceived  inflation  through
continued  monetary  policy  tightening  in 2000.  Until the  inflation  picture
becomes  clearer,  we  expect  interest  rates to  remain  largely  range-bound.
Accordingly,  we will  continue  to seek  the  most  attractive  relative  value
opportunities  and utilize our proprietary  risk management  systems to help the
Trust to achieve its investment objectives.

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

Sincerely,

Dear Shareholder:

      We are pleased to present the annual report for The BlackRock  Target Term
Trust Inc.  ("the Trust") for the year ended December 31, 1999. 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  primary  investment  objective  is to return $10 per share (its initial
offering price) to  shareholders  on or about December 31, 2000.  Although there
can  be no  guarantee,  BlackRock  believes  that  the  Trust  can  achieve  its
investment objective.  The Trust will seek to achieve its objective 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:

                             12/31/99  12/31/98    CHANGE     HIGH        LOW
                             --------  --------    ------     ----        ---

NET ASSET VALUE (NAV)         $9.78     $10.13     (3.46%)   $10.18      $9.78
5-YEAR U.S. TREASURY NOTE      6.34%      4.54%    39.65%      6.34%      4.46%


THE FIXED INCOME MARKETS

      Despite the  complete  reversal of last year's 0.75% easing by the Federal
Reserve, the expansion of the U.S. economy continues intact. At the end of 1999,
the labor markets  remain tight,  economic  growth  remains strong and inflation
pressures appear  restrained by offsetting gains in productivity.  However,  the
factors that should eventually lead to higher interest rates also remain intact:
higher equity and commodity  prices,  a confident  consumer,  labor markets that
continue  to tighten  and a global  recovery  that will boost U.S.  exports  and
reduce  the trade  deficit.  Along with  consumer  confidence,  consumer  credit
continues to advance as evidenced in remarkably strong holiday sales.

      Although  the  Federal  Open  Market  Committee  took no  action  at their
December  meeting,  this  should not be  interpreted  to mean that the threat of
inflationary  forces  has  dissipated.  We  expect  that  continued  above-trend
economic  strength,  tight  labor  markets  and the  need to  drain  the  excess
liquidity  that the Fed provided the financial  markets in the months leading up
to Y2K will warrant  additional Fed tightening in 2000.  Despite our outlook for
additional  Fed moves we believe  that the market has  adequately  priced in the
degree of tightening  necessary to  successfully  engineer an economic slow down
later this year.

      Treasury yields  increased  significantly  during 1999,  continuing  their
year-long  slide in price.  Over the course of the year the yield of the 30-year
Treasury  has  increased by nearly 139 basis  points  (1.39%).  The yield of the
5-Year Treasury

                                        2

<PAGE>

posted a net increase of 180 basis points  (1.80%),  beginning 1999 at 4.54% and
closing on December  31, 1999 at 6.34%.  Bond  prices,  which move  inversely to
their yields, have continued to be punished as the market reacted to strength of
the economy and uncertainty of future Fed action. During the fourth quarter, the
short and intermediate  sections of the yield curve  underperformed the long end
of the curve. As we move into 2000, we anticipate a continued  flattening of the
yield  curve as a result of an active  Federal  Reserve and  potential  Treasury
repurchases of long maturity debt.

      A combination of shrinking  supply,  and a decline in prepayment  rates in
response to a reduction in refinancing activity,  allowed mortgage securities to
outperform  the  broader  investment  grade  market.  Falling  bond  prices kept
mortgages rates near 8%, which has significantly  affected  refinancing activity
reducing an important source of new mortgage origination.  For the period ending
December 31st the LEHMAN BROTHERS MORTGAGE INDEX, mortgages posted a 1.86% total
return versus -0.82% for the LEHMAN BROTHERS AGGREGATE INDEX. As the origination
of new mortgages  continues to decline,  the outlook for the mortgage  sector is
favorable.  Despite  the rich  valuations  of  mortgages,  a likely  shortage of
yield-oriented  products  will draw  investors  to the  mortgage  sector as they
execute their investment plans in 2000.

      Investment   grade  corporate   securities   underperformed   the  broader
investment grade bond market,  as corporates  measured by the MERRILL LYNCH U.S.
CORPORATE  MASTER  INDEX  returned  -1.87%,  as compared to the LEHMAN  BROTHERS
AGGREGATE  INDEX'S -0.82%.  1999 was marked by a large supply of corporate bonds
due to M&A activity and issuers rushing to market ahead of Y2K. While we believe
M&A  activity  will  follow  through in 2000,  higher  rates  combined  with the
increased  issuance in 1999 should result in a more moderate  supply  picture in
2000.  Despite a very buoyant economic  environment,  credit parameters have not
been improving in the investment  grade corporate bond universe raising concerns
about  vulnerability to a down turn. As a result, we have generally  implemented
an "up in credit" strategy in portfolios.

      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 offer attractive yield spreads over Treasury
securities,  and an  emphasis on bonds with  maturity  dates  approximating  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.

      Consistent  with the Trust's  primary  investment  objective the continual
reinvestment  of cash flows into shorter  maturity  securities  over time as the
Trust approaches its maturity date results in a natural  reduction in the amount
of net  investment  income  generated  by the Trust.  Therefore,  after  careful
evaluation of the current and  anticipated  level of the Trust's net  investment
income, the Board of Directors voted to reduce the Trust's monthly dividend from
$0.04167 ($0.50 annualized) to $0.03875 ($0.465  annualized)  effective with the
December 31, 1999 dividend payment.

      During the reporting period the Trust maintained its significant weighting
in Zero Coupon  Bonds,  investment  grade  corporate  bonds and  well-structured
mortgage securities such as commercial mortgage-backed securities.

       As a result of an  internal  reorganization,  effective  January 1, 2000,
BlackRock  Advisors,  Inc. has replaced BlackRock  Financial  Management Inc., a
wholly-owned subsidiary of BlackRock Advisors, Inc. as the Advisor of the Trust.
The investment management and other personnel responsible for providing services
to the Trust did not change as a result of the  reorganization.  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

which were not addressed in this report.

THE BLACKROCK TARGET TERM TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
NOTE 1. ORGANIZATION &           The BlackRock Target ACCOUNTING Term Trust Inc.
POLICIES                         (the  "Trust"),  a Maryland  corporation,  is a
                                 diversified,  closed-end  management investment
company.  The primary 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. 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,  interest rate swaps,  caps,  floors and  non-exchange  traded
options 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.  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 having a remaining  maturity of 60 days or less are
valued at amortized cost which approximates market value.

REPURCHASE AGREEMENTS: 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, or collections of 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  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 portfo-


                                       13

<PAGE>

lio 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.
Interest 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  interest  rate  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 in a manner similar to more generic options described above.

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  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

                                       14
<PAGE>

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.

      The Trust  did not  engage  in  security  lending  during  the year  ended
December 31, 1999.

INTEREST  RATE CAPS:  Interest  rate caps are  similar to  interest  rate swaps,
except  that one party  agrees to pay a fee,  while  the  other  party  pays the
excess, if any, of a floating rate over a specified fixed or floating rate.

      Interest rate caps are intended to both manage the duration of the Trust's
portfolio and its exposure to changes in short-term rates.  Owning interest rate
caps reduces the  portfolio's  duration,  making it less sensitive to changes in
interest rates from a market value  perspective.  The effect on income  involves
protection from rising short-term rates,  which the Trust experiences  primarily
in the form of leverage.

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

      Transactions  fees paid or received by the Trust are  recognized as assets
or  liabilities  and amortized or accreted into interest  expense or income over
the life of the  interest  rate cap.  The  asset or  liability  is  subsequently
adjusted to the current market value of the interest rate cap purchased or sold.
Changes in the value of the interest rate cap are recognized as unrealized gains
and losses.

INTEREST  RATE FLOORS:  Interest rate floors are similar to interest rate swaps,
except  that one party  agrees to pay a fee,  while  the  other  party  pays the
deficiency, if any, of a floating rate under a specified fixed or floating rate.

      Interest rate floors are used by the Trust to both manage the
duration of the  portfolio  and its exposure to changes in  short-term  interest
rates. Selling interest rate floors reduces the portfolio's duration,  making it
less sensitive to changes in interest rates from a market value perspective. The
Trust's  leverage  provides extra income in a period of falling  rates.  Selling
floors reduces some of that advantage by partially  monetizing it as an up front
payment which the Trust receives.

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

      Transactions  fees paid or received by the Trust are  recognized as assets
or  liabilities  and amortized or accreted into interest  expense or income over
the life of the interest  rate floor.  The asset or  liability  is  subsequently
adjusted to the current  market  value of the interest  rate floor  purchased or
sold.  Changes  in the  value of the  interest  rate  floor  are  recognized  as
unrealized gains and losses.

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.

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  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.

                                       15
<PAGE>

      Income  distributions  and capital gain  distributions  are  determined in
accordance with income tax regulations which may differ from generally  accepted
accounting principles.

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 $1,636,395 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
"Advisor"),  a wholly-owned  subsidiary of BlackRock Advisors,  Inc., which is a
wholly-owned  subsidiary  of  BlackRock,  Inc.,  which  in turn  is an  indirect
majority-owned  subsidiary  of  PNCBank  Corp.  The Trust has 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 Advisor 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 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                Purchases and sales of  investment  securities,
SECURITIES                       other than  short-term  investments  and dollar
                                 rolls,  for the year ended  December  31,  1999
aggregated $200,929,757 and $153,909,847, 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, 1999, the Trust
held 5.9% of its portfolio assets in restricted securities.

      The Trust may from time to time purchase in the secondary  market  certain
mortgage pass-through  securities packaged or master serviced by affiliates such
as 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 December 31,
1999 was  substantially  the  same as the  basis  for  financial  reporting  and
accordingly,  net  unrealized  depreciation  for federal income tax purposes was
$967,960   (gross   unrealized   appreciation--$18,173,381;   gross   unrealized
depreciation--$19,141,341.)

      For federal income tax purposes, the Trust had a capital
loss  carryforward at December 31, 1999 of  approximately  $5,594,000 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.

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 year ended  December  31, 1999 was  approximately  $394,414,893  at a
weighted  average  interest rate of  approximately  4.83%. The maximum amount of
reverse  repurchase  agreements  outstanding at any month-end  during the period
ended December 31, 1999 was $419,620,963 as of January 31, 1999 which was 29% of
total assets.

                                       16
<PAGE>

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 year ended December
31, 1999.

NOTE 5. CAPITAL                  There are 200 million  shares of $.01 par value
                                 common  stock  authorized.  Of  the  95,460,639
shares outstanding at December 31, 1999, the Advisor owned 10,639 shares.

                         REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

The Shareholders and Board of Directors of
The BlackRock Target Term Trust Inc.:

We have  audited the  accompanying  statement of assets and  liabilities  of The
BlackRock Target Term Trust Inc., including the portfolio of investments,  as of
December 31, 1999,  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
five years in the period then ended.  These  financial  statements and financial
highlights are the responsibility of the Trust's management.  Our responsibility
is to express an opinion on these financial  statements and financial highlights
based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
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, 1999, 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,  the financial  statements and financial  highlights referred to
above present fairly, in all material  respects,  the financial  position of The
BlackRock Target Term Trust Inc. as of December 31, 1999, and the results of its
operations,  its cash  flows,  the  changes in its net assets and its  financial
highlights  for the  respective  stated  periods in  conformity  with  generally
accepted accounting principles.

                                 TAX INFORMATION
- --------------------------------------------------------------------------------

      We wish to  advise  you as to the  federal  tax  status of  dividends  and
distributions  paid by the Trust from net  investment  income during the taxable
year ended December 31, 1999.

      During the fiscal year ended  December 31, 1999,  the Trust paid aggregate
dividends  of  $0.4973  per  share  to  investors  taxable  as  1999  income  to
shareholders  of record from January 1 toDecember  31, 1999.  For Federal Income
tax purposes the  dividends  you  received are  reportable  in your 1999 federal
income tax returns as ordinary income.  Further, we wish to advise you that your
income dividends do not qualify for the dividends received deduction.

      We are required by Massachusetts,  Missouri, and Oregon to inform you that
dividends  which have been derived from interest on federal  obligations are not
taxable to  shareholders.  Please be advised that 90.59% of the  dividends  paid
from ordinary income in the fiscal year ended December 31, 1999 qualify for each
of these states' tax exclusion.

      For the purpose of preparing  your 1999 annual  federal income tax return,
however, you should report the amounts as reflected on the appropriate Form 1099
DIV which was mailed to you in January 2000.

                           DIVIDEND REINVESTMENT PLAN

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

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

      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 primary 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.

WHO MANAGES THE TRUST?
BlackRock Advisors, Inc. is an SEC-registered investment advisor. As of December
31, 1999,  BlackRock and its  affiliates  (together,  "BlackRock")  managed $165
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 $27 billion family of open-end funds.  BlackRock manages
over 580 accounts, 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 ADVISOR'S INVESTMENT STRATEGY?
The Advisor will seek to meet the Trust's  investment  objective by managing the
assets of the Trust so as to return the initial  offering  price ($10 per share)
at maturity.  The Advisor 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,
the  Advisor  expects  that the  value of the  securities  which  have  matured,
combined  with the value of he  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 order to maintain  competitive  yields as the Trust  approaches  maturity and
depending on market conditions,  the Advisor will attempt to purchase securities
with call  protection  or  maturities  as close to the Trust's  maturity date as
possible. Securities with call protection should provide the portfolio with some
degree of protection against  reinvestment risk during times of lower prevailing
interest rates. Since the Trust's primary goal is to return the initial offering
price at maturity,  any cash that the Trust  receives prior to its maturity date
(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. It is important to
note that the Trust will be  managed  so as to  preserve  the  integrity  of the
return of the initial offering price.

HOW ARE THE TRUST'S SHARES PURCHASED AND SOLD? DOES THE TRUST PAY DIVIDENDS
REGULARLY?
The  Trust's  shares are traded on the New York Stock  Exchange  which  provides
investors with  liquidity on a daily basis.  Orders to buy or sell shares of the
Trust must be placed through a registered broker or financial 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 & Trust Company.  Investors who wish to hold shares in a brokerage  account
should check with their financial  advisor to determine  whether their brokerage
firm offers dividend reinvestment services.

LEVERAGE CONSIDERATIONS IN A TERM TRUST
Under current  market  conditions,  leverage  increases the income earned by the
Trust.  The  Trust  employs  leverage  primarily  through  the  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.

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.  The Advisor's portfolio managers  continuously  monitor and
regularly  review the  Trust's  use of  leverage  and the Trust may  reduce,  or
unwind,  the amount of  leverage  employed  should  the  Advisor  consider  that
reduction to be in the best interests of the shareholders.

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

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

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

INTEREST-ONLY SECURITIES (IO). The yield to maturity on an IO class is extremely
sensitive  to the rate of  principal  payments  (including  prepayments)  on the
related  underlying  mortgage assets, and a rapid rate of principal payments may
have a material  adverse  effect on such  security's  yield to maturity.  If the
underlying  mortgage assets experience  greater than anticipated  prepayments of
principal,  the Trust may fail to recoup fully its initial  investment  in these
securities  even  if the  securities  are  rated  AAA by S&P or Aaa by  Moody's.

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  (NYSE symbol:  BTT) 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 up to 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.

                                 FHLMC.

INVERSE-FLOATINGRATE  MORTGAGES: Mortgage  instruments  with coupons that adjust
                                 at periodic  intervals  according  to a formula
                                 which  sets   inversely  with  a  market  level
                                 interest rate index.

INTEREST-ONLY SECURITIES:        Mortgage securities including CMBS that receive
                                 only the interest cash flows from an underlying

                                 is the  price  at which  one  share of the fund
                                 trades  on the stock  exchange.  If you were to

                                 the market price.

MORTGAGE DOLLAR ROLLS:           A  mortgage  dollar  roll is a  transaction  in
                                 which   the   Trust    sells    mortgage-backed
                                 securities  for  delivery in the current  month
                                 and  simultaneously   contracts  to  repurchase
                                 substantially  similar  (although not the same)
                                 securities on a specified  future date.  During
                                 the "roll"  period,  the Trust does not receive
                                 principal   and   interest   payments   on  the
                                 securities,  but is  compensated  for giving up
                                 these payments by the difference in the current
                                 sales  price (for which the  security  is sold)
                                 and lower  price  that the  Trust  pays for the
                                 similar security at the end date as well as the
                                 interest  earned  on the cash  proceeds  of the
                                 initial sale.

MORTGAGE PASS-THROUGHS:          Mortgage-backed   securities  issued  by  FNMA,
                                 FHLMC, GMMA or FHA.

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.

PRINCIPAL-ONLY                   SECURITIES:  Mortgage  securities  that receive
                                 only  the   principal   cash   flows   from  an
                                 underlying pool of mortgage loans or underlying
                                 pass-through securities.

PROJECT LOANS:                   Mortgages  for  multi-family,  low- to  middle-
                                 income housing.

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

REMIC:                           A real estate mortgage  investment conduit is a
                                 multiple-class      security      backed     by
                                 mortgage-backed  securities  or whole  mortgage
                                 loans  and  formed  as  a  trust,  corporation,
                                 partnership,  or segregated pool of assets that
                                 elects to be treated as a REMIC for federal tax
                                 purposes.  Generally, FNMA REMICs are 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
AGREEMENTS:                      In a reverse  repurchase  agreement,  the Trust
                                 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
SECURITIES:                      Arrangements  in  which  a pool  of  assets  is
                                 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.
