                 CONSOLIDATED SEMI-ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISER

                                                                   July 31, 1999



Dear Shareholder:

     Since the Trust's last report,  interest rates rose sharply as U.S economic
growth remained strong, labor markets tightened and international  markets began
to recover. In light of these factors, the Federal Reserve's Federal Open Market
Committee increased short-term interest rates by 25 basis points in June, citing
a concern that inflation might start to accelerate.

     In tandem with the Fed's  recent  rate  tightening,  BlackRock  has taken a
defensive interest rate stance. With the Treasury curve currently pricing in the
possibility  of another Fed  tightening  by year-end,  we believe that  interest
rates will trade in a relatively  narrow range until the economy  shows signs of
slowing.

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

Sincerely,


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

Dear Shareholder:

     We are  pleased  to  present  the  semi-annual  report  for  The  BlackRock
Advantage  Term Trust Inc. ("the Trust") for the six months ended June 30, 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  "BAT".  The
Trust's  investment  objective is to return $10 per share (its initial  offering
price) to  shareholders  on or about  December  31,  2005 while  providing  high
current income. Although there can be no guarantee,  BlackRock is confident that
the  Trust  can  achieve  its  investment  objectives.  The  Trust  seeks  these
objectives by investing in investment grade fixed income  securities,  including
corporate debt securities,  mortgage-backed securities backed by U.S. Government
agencies  (such  as  Fannie  Mae,  Freddie  Mac  or  Ginnie  Mae),  asset-backed
securities and commercial mortgage-backed  securities. All of the Trust's assets
must be rated at least "BBB" by Standard & Poor's or "Baa" by Moody's at time of
purchase or be issued or guaranteed by the U.S. Government or its agencies.

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

THE FIXED INCOME MARKETS

     The past six months have witnessed  continued  rapid  expansion of the U.S.
economy.  GDP growth for the second  quarter of 1999 is  estimated  at an annual
rate of 3.5%-4%,  far exceeding  the  historical  non-inflationary  level of 2%.
While  BlackRock  believes that growth may slow down in the second half of 1999,
we anticipate  GDP to remain above 3% for the year. In spite of strong  domestic
economic growth,  inflationary  forces continue to remain contained;  still, the
Federal  Reserve chose to raise its target for the federal funds rate from 4.75%
to 5.00% at its June meeting. The Fed cited an easing of financial strain, tight
labor markets and a firming of foreign economies in the release accompanying the
move. The Fed dropped its tightening bias to a neutral bias, which should reduce
the  likelihood  of  another  hike  at the  August  24th  meeting.  However,  an
additional  25-50 basis points of  tightening  by year end is  possible,  as the
combination  of a very strong  domestic  economy and an  improving  situation in
Europe and Japan may allow for tighter monetary policy.

     U.S. Treasury securities  dramatically  reversed their fourth quarter gains
in the  first  half of 1999.  The  yield of the  10-Year  Treasury  posted a net
decline of 113 basis points (1.13%), beginning 1999 at 4.65% and closing on June
30, 1999 at 5.78%.  Strong  economic  numbers led the Federal Reserve to adopt a
tightening bias on May 18, 1999 and ultimately raised interest rates by 25 basis
points  on June 30,  1999.  The  Federal  Reserve  eased  rates by 0.75% in 1998
because of the  global  financial  crisis  but cited in their June 1999  meeting
"Since  then much of the  financial  strain has eased,  foreign  economies  have
firmed and economic  activity in the U.S. has moved forward at a brisk pace." We
anticipate Treasuries will trade in a relatively narrow range for the balance of
1999 unless the Fed takes further action.

     As interest rates rose and alleviated  prepayment fear, mortgage securities
outperformed the broader investment grade bond market. For the period ended June
30th the LEHMAN  BROTHERS  MORTGAGE  INDEX  posted a 0.53% total  return  versus
- -1.39%  for  the  LEHMAN   BROTHERS   AGGREGATE   INDEX.   After   significantly
underperforming  Treasuries in 1998  mortgages  experienced a significant  rally
late in 1998 following  through into the first quarter of 1999.  Although yields
have tightened  significantly from their crisis levels in 1998, mortgages remain
compelling as a record  issuance has come to market and kept yields  attractive.
Although higher  mortgage rates have reduced  prepayment  fears,  mortgage rates
still remain at historically low levels.

     Investment grade corporate securities underperformed the broader investment
grade bond market,  as corporates  measured by the MERRILL LYNCH U.S.  CORPORATE
MASTER  INDEX  returned  -2.52%,  as compared to the LEHMAN  BROTHERS  AGGREGATE
INDEX'S -1.39%.  Corporate  profitability  continues to be the driving factor of
corporate  bond  performance  and profit  growth  remains  under  pressure  from
overseas  markets and a strong labor market.  Deteriorating  fundamentals  (four
times as many  downgrades  as upgrades in the first  quarter  according  to S&P)
combined with  weakening  profit growth and increased  issuance will continue to
pressure the corporate  market.  Investor appetite for credit and liquidity risk
remains  suppressed  after last year's  volatility.  We anticipate new supply to
start to taper off early in the fourth  quarter and relieve some of the pressure
that investment grade corporates have been experiencing.

     In accordance  with the Trust's primary  investment  objective of returning
the initial  offering  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 maturity dates approximating the Trust's
termination date of December 31, 2005.  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
$0.0520833 ($0.6250  annualized) to $0.050 ($0.6000  annualized)  effective with
the March 31, 1999 dividend payment.

     During the reporting  period,  the most significant  additions have been in
the asset-backed security (ABS) sector and Treasuries.  Additionally,  the Trust
maintained its  significant  weighting in investment  grade  corporate bonds and
well-structured   mortgage   securities   such  as  commercial   mortgage-backed
securities  (CMBS).  To  finance  these  purchases,  the  Trust  primarily  sold
corporates  and  mortgages  to  add  liquidity  so  that  the  portfolio   could
participate in the new issue market for corporates and asset-backed  securities,
which are offering attractive yields relative to existing bonds.

     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  Advantage Term Trust Inc. Please

THE BLACKROCK ADVANTAGE TERM TRUST INC.
NOTES TO CONSOLIDATED
FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION & POLICIES

The BlackRock  Advantage  ACCOUNTING  Term Trust Inc. (the "Trust"),  a Maryland
corporation,  is a diversified,  closed-end  management  investment company. The
Trust's investment  objective is to manage a portfolio of investment grade fixed
income  securities  that will  return $10 per share to  investors  on or shortly
before  December 31, 2005 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.

   On October 31, 1998, the Trust transferred a substantial portion of its total
assets to a 100%  owned  regulated  investment  company  subsidiary  called  BAT
Subsidiary,  Inc.These  consolidated financial statements include the operations
of both the Trust and its  wholly-owned  subsidiary  after  eliminattion  of all
intercompany transactions and balances.

   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 unless the Trust's Board of Directors determines that such price
does not  reflect  its fair  value,  in which case it will be valued at its fair
value as determined by the Trust's Board of Directors.  Any  securities or other
assets for which such current market  quotations  are not readily  available are
valued at fair value as determined in good faith under procedures established by
and under the general  supervision  and  responsibility  of the Trust's Board of
Directors.

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

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


                                       11

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 anytime 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.

INTEREST  RATE  SWAPS:  In a simple  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 expires 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 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


                                       12


<PAGE>


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 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 payments 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.

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.  The  Trust  did  not  engage  in
securities lending during the six months ended June 30, 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 subsequentlyadjusted 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 or 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 the 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


                                       13


<PAGE>


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  substantially  all taxable  income to  shareholders.  Therefore,  no
federal income tax provision is required.  As part of its tax planning strategy,
the Trust  intends to 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.

   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.


NOTE 2. AGREEMENTS

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

   The  investment  advisory  fee paid to the  Adviser  is  computed  weekly and
payable  monthly at an annual  rate of 0.50% 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
through  December 31, 2000 and 0.08% from January 1, 2001 to the  termination or
liquidation of the Trust.

   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 SECURITIES

Purchases and sales of investment securities,  other than short-term investments
and dollar rolls, for the six months ended June 30, 1999 aggregated  $15,113,061
and $9,328,525, respectively.

   The Trust may invest up to 85% of its total  assets in  securities  which are
not readily  marketable,  including those which are restricted as to disposition
under securities law ("restricted securities"). At June 30, 1999, the Trust held
1.0% of its portfolio assets in illiquid securities.

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

   The federal income tax basis of the Trust's  investments at June 30, 1999 was
$139,183,137 and,  accordingly,  net unrealized  appreciation for federal income
tax purposes was $5,479,554  (gross unrealized  appreciation--$8,078,842;  gross
unrealized depreciation--$2,599,288).

   For federal income tax purposes, the Trust had a capital loss carryforward at
December 31, 1998 of approximately  $2,735,000,  of which $2,519,000  expires in
2004 and $216,000 expires in 2005. 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 six months ended June 30, 1999 was  approximately  $46,929,418 at a weighted
average  interest rate of  approximately  4.92%.  The maximum  amount of reverse
repurchase  agreements  outstanding at any month-end  during the year ended June
30, 1999 was $51,006,335 as of January 31, 1999 which was 37.2% 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
six months ended June 30, 1999.


NOTE 5. CAPITAL

There are 200 million shares of $.01 par value common stock  authorized.  Of the
9,510,667 shares outstanding at June 30, 1999, the Adviser owned 10,667 shares.

NOTE 6. DIVIDENDS

Since June 30, 1999, the Board of Directors of the Trust declared dividends from
undistributed  earnings of $0.05 per share payable July 30, 1999 to shareholders
of record on July 15, 1999.

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

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

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

      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 fee 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 ADVANTAGE TERM TRUST INC.
                             ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------

      YEAR 2000 READINESS  DISCLOSURE.  The Trust is currently in the process of
evaluating its information  technology  infrastructure for Year 2000 compliance.
Substantially  all  of the  Trust's  information  systems  are  supplied  by the
Adviser.  The  Adviser has  advised  the Trust that it is  currently  evaluating
whether such systems are year 2000  compliant and that it expects to incur costs
of up to approximately five hundred thousand dollars to complete such evaluation
and to make any modifications to its systems as may be necessary to achieve Year
2000 compliance.  The Adviser has advised the Trust that it has fully tested its
systems for Year 2000 compliance. The Trust may be required to bear a portion of
such cost  incurred by the Adviser in this  regard.  The Adviser has advised the
Trust that it does not anticipate  any material  disruption in the operations of
the  Trust as a result  of any  failure  by the  Adviser  to  achieve  Year 2000
compliance.  There can be no assurance that the costs will not exceed the amount
referred  to  above or that  the  Trust  will not  experience  a  disruption  in
operations.

      The Adviser has advised the Trust that it is in the process of  evaluating
the Year 2000 compliance of various  suppliers of the Adviser and the Trust. The
Adviser has advised the Trust that it has  communicated  with such  suppliers to
determine their Year 2000 compliance  status and the extent to which the Adviser
or the Trust could be affected by any supplier's Year 2000 compliance issues. To
date, the Adviser has received responses from all such suppliers with respect to
their Year 2000  compliance,  and there can be no assurance  that the systems of
such suppliers, who are beyond the Trust's control, will be Year 2000 compliant.
In the event that any of the Trust's  significant  suppliers do not successfully
and timely  achieve Year 2000  compliance,  the Trust's  business or  operations
could be adversely affected. The Adviser has advised the Trust that it is in the
process  of  preparing  a  contingency  plan for  Year  2000  compliance  by its
suppliers.  There  can be no  assurance  that  such  contingency  plan  will  be
successful in preventing a disruption of the Trust's operations.

      The  Trust is  designating  this  disclosure  as its Year  2000  readiness
disclosure  for all  purposes  under the Year  2000  Information  and  Readiness
Disclosure  Act and the  foregoing  information  shall  constitute  a Year  2000
statement for purposes of that Act.

      ANNUAL MEETING OF TRUST SHAREHOLDERS.  There have been no material changes
in the Trust's investment  objectives or policies that have not been approved by
the  shareholders  or to its charter or by-laws or in the principal risk factors
associated  with  investment  in the  Trust.  There  have been no changes in the
persons who are  primarily  responsible  for the  day-to-day  management  of the
Trust's Portfolio.

     The Annual Meeting of Trust  Shareholders  was held May 19, 1999 to vote on

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


THE TRUST'S INVESTMENT OBJECTIVE

The BlackRock  Advantage Term Trust Inc.'s  investment  objective is to manage a
portfolio of investment  grade fixed income  securities that will return $10 per
share (the initial  public  offering price per share) to investors on or shortly
before December 31, 2005 while providing high monthly income.

WHO MANAGES THE TRUST?

BlackRock  Financial  Management,   Inc.   ("BlackRock")  is  an  SEC-registered
investment  adviser.  BlackRock and its  affiliates  currently  manage over $141
billion  on behalf of  taxable  and  tax-exempt  clients  worldwide.  Strategies
include  fixed  income,  equity and cash and may  incorporate  both domestic and
international   securities.   Domestic  fixed  income  strategies   utilize  the
government,  mortgage,  corporate and municipal bond sectors.  BlackRock manages
twenty-one  closed-end  funds that are traded on either the New York or American
Stock exchanges,  and a $25 billion family of open-end funds.  BlackRock manages
over 470 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 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 Adviser will implement a conservative  strategy that will seek
to closely  match the  maturity of the assets of the  portfolio  with the future
return of the initial investment at the end of 2005. 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.

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

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  affect 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 (NYSEsymbol: BAT) and as such are
subject  to supply  and demand  influences.  As a result,  shares may trade at a
discount or a premium to their net asset value.

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

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

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

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

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

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

INVERSE-FLOATING RATE MORTGAGE:   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   pool   of   mortgage   loans   or
                                  underlying pass-through securities. Also known
                                  as a strip.

MARKET PRICE:                     Price per share of a  security  trading in the
                                  secondary market.  For a closed-end fund, this
                                  is the  price at which  one  share of the fund
                                  trades on the stock  exchange.  If you were to
                                  buy or sell  shares,  you would pay or receive
                                  the market price.

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 Fannie
                                  Mae, Freddie Mac or Ginnie Mae.

MULTIPLE-CLASS PASS-THROUGHS:     Collateralized Mortgage Obligations.

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,  THE NEW
                                  YORK  TIMES  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. Also known as a strip.


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, Fannie Mae 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.

AGREEMENTS:
  REVERSE                         REPURCHASE 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.


STRIP 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.

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

      BlackRock Financial  Management,  Inc.  ("BlackRock") is an SEC-registered
investment  adviser.  BlackRock and its  affiliates  currently  manage over $141
billion  on behalf of  taxable  and  tax-exempt  clients  worldwide.  Strategies
include  fixed  income,  equity and cash and may  incorporate  both domestic and
international securities. BlackRock manages twenty-one closed-end funds that are
traded on either the New York or  American  stock  exchanges,  and a $25 billion
family of open-end funds. BlackRock manages over 470 accounts,  domiciled in the
United States and overseas.

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

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

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

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