                                                                January 31, 1998


Dear Trust Shareholder:

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

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

      There are exciting developments  occurring at BlackRock that we would like
to share with you. As you may know,  BlackRock was acquired by PNC Bank, N.A. in
1995. In early 1998 the five investment  management  firms that comprise the PNC
Asset Management Group were consolidated under the BlackRock umbrella. This will
result in BlackRock Inc.  becoming a $100 billion money  management firm ranking
it among the 25  largest  in the  country.  We look  forward to using our global
investment management expertise to present exciting investment  opportunities to
closed-end fund shareholders in the future.

      This report contains detailed market and portfolio strategy  commentary by
your Trust's  managers in addition to the Trust's audited  financial  statements
and a detailed portfolio listing. We thank you for your continued  investment in
the Trust and wish you a successful new year.


Sincerely,






/s/                                                  /s/

Dear Shareholder:

      We are pleased to present  the annual  report for The  BlackRock  New York
Insured Municipal 2008 Term Trust Inc. ("the Trust") for the year ended December
31, 1997.  We would like to take this  opportunity  to review the Trust's  stock
price and net asset value (NAV) performance, summarize developments in the fixed
income markets and discuss recent portfolio management activity.

      The  Trust is a  non-diversified  closed-end  bond fund  whose  investment
objective is to manage a portfolio of municipal debt securities that will return
$15 per share (an amount equal to the Trust's  initial public offering price) to
investors on or about  December 31, 2008,  while  providing  high current income
exempt from  regular  federal and New York State and City income tax.  The Trust
seeks to achieve this  objective by investing in high credit  quality  ("AAA" or
insured to "AAA") New York  tax-exempt  general  obligation  and  revenue  bonds
issued by city, county and state municipalities.

The table below  summarizes the changes in the Trust's stock price and net asset
value over the past year:


                       ---------------------------------------------------------
                        12/31/97      12/31/96    CHANGE      HIGH       LOW
- --------------------------------------------------------------------------------
 STOCK PRICE            $15.875       $15.125      4.96%     $16.00     $14.75
- --------------------------------------------------------------------------------
 NET ASSET VALUE (NAV)  $16.53        $15.76       4.89%     $16.53     $15.39
- --------------------------------------------------------------------------------

THE FIXED INCOME MARKETS

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

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

      Municipal bonds, as measured by the LEHMAN MUNICIPAL BOND INDEX,  posted a
9.20%  total  return for the year,  versus  9.68% for the  taxable  bond  market
(measured by the LEHMAN AGGREGATE INDEX).  The substantial  decline in municipal
interest rates resulted in 1997 being the third largest  issuance year on record
(a  19%  increase  over  1996),   which  negatively   impacted   municipal  bond
performance.  After  keeping pace with the  Treasury  market rally in the second
quarter,  municipals  cheapened in relation to Treasuries during the latter half
of the year due to reduced  participation  by retail investors at lower interest
rate levels and increased supply.

      New York State's  economy  remained strong over the past twelve months and
the State's  fiscal year  1997-98  budget  surplus may be as high as $1 billion.
Wall Street's  prosperity,  fueled by the continued bull market, has resulted in
increased tax revenues that have contributed to the State's income growth. These
increased  revenues  have  mitigated  the impact of Governor  Pataki's tax cuts;
further  tax  reductions  have  been  proposed  to  make  New  York  State  more
economically competitive. The overall health of the State's economy led Standard
& Poor's to raise New York's credit rating from A- to A in September 1997.


                                       2


<PAGE>


      Looking forward, we expect issuance of municipal  securities in 1998 to be
similar  to 1997  levels,  with an  increase  in new  supply  being  offset by a
decrease  in  refunding  supply.  BlackRock  remains  focused  on  high  quality
municipal  securities,  because the yield  advantage of  purchasing  lower rated
securities  remains  marginal.  The strong  state of the  economy is expected to
continue,  providing strong fundamentals for municipal issuers. We expect to see
more discussions  about tax reform towards the end of the first quarter of 1998,
which may create buying opportunities.


THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY

      The Trust's  portfolio is actively  managed to diversify  exposure  across
various  sectors,  issuers,  revenue  sources and  security  types.  BlackRock's
investment strategy emphasizes a relative value approach, which allows the Trust
to capitalize upon changing  market  conditions by rotating  municipal  sectors,
credits and coupons.  Portfolio  trading activity was very low during 1997, as a
majority of the bonds in the  portfolio  are trading at prices  which,  if sold,
would  result in a taxable  capital  gain.  Additionally,  as these  bonds  were
purchased in higher interest rate environments.  Were they to be sold, the Trust
would be forced to reinvest the proceeds in lower yielding  securities.  Both of
these  factors led us to decide that the most  prudent  investment  strategy for
1997 was to maintain the current portfolio structure.

      Additionally,  the  Trust  employs  leverage  to  enhance  its  income  by
borrowing at  short-term  municipal  rates and  investing the proceeds in longer
maturity  issues  that have  higher  yields.  The  degree to which the Trust can
benefit  from its use of  leverage  may affect its  ability to pay high  monthly
income. The Trust has experienced  favorable short-term municipal rates over the
past year. The Federal Reserve's  decision to raise the Fed funds target rate in
March 1997 did not  significantly  impact the short end of the  municipal  yield
curve, allowing the rates the Trust pays to preferred  shareholders (the Trust's
leverage cost) to remain affordable.

THE BLACKROCK NEW YORK INSURED MUNICIPAL 2008 TERM TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------


NOTE 1. ACCOUNTING POLICIES
The BlackRock New York Insured Municipal 2008 Term Trust Inc. (the "Trust"), was
organized  in  Maryland  on  August  7,  1992  as a  non-diversified  closed-end
management  investment company.  The Trust's investment objective is to manage a
non-diversified  portfolio of high quality  securities  that will return $15 per
share to investors on or about December 31, 2008 while providing  current income
exempt from regular federal,  New York State and New York City income taxes. The
ability  of  issuers  of  debt  securities  held  by the  Trust  to  meet  their
obligations  may be affected by economic  developments  in the state, a specific
industry  or  region.  No  assurance  can be given that the  Trust's  investment
objective will be achieved.

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

SECURITIES VALUATION:  Municipal securities  (including  commitments to purchase
such  securities  on a  "when-issued"  basis)  are valued on the basis of prices
provided  by  a  pricing  service  which  uses   information   with  respect  to
transactions  in bonds,  quotations  from bond dealers,  market  transactions in
comparable   securities  and  various   relationships   between   securities  in
determining values. Any securities or other assets for which such current market
quotations  are not readily  available are valued at fair value as determined in
good faith under procedures established by and under the general supervision and
responsibility of the Trust's Board of Directors.

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

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME:  Securities  transactions  are
recorded  on the trade date.  Realized  gains and losses are  calculated  on the
identified cost basis.  Interest income is recorded on the accrual basis and the
Trust  amortizes  premium and accretes  original  issue  discount on  securities
purchased  using the interest  method.  

FEDERAL  INCOME  TAXES:  It is the  Trust's  intention  to  continue to meet the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies  and to distribute  sufficient  net income to  shareholders.  For this
reason and because  substantially  all of the Trust's  gross income  consists of
tax-exempt interest, no federal income tax provision is required.  

DIVIDENDS  AND  DISTRIBUTIONS:   The  Trust  declares  and  pays  dividends  and
distributions to common  shareholders  monthly from net investment  income.  Net
capital  gains,  if any,  in excess  of loss  carryforwards  may be  distributed
annually.  Dividends and  distributions  are recorded on the  ex-dividend  date.
Dividends and distributions to preferred shareholders are accrued and determined
as described in Note 4. 

ESTIMATES:  The preparation of financial statements in conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

NOTE 2. AGREEMENTS 
The  Trust  has  an  Investment  Advisory  Agreement  with  BlackRock  Financial
Management,  Inc. (the "Adviser"),  a wholly-owned  corporate  subsidiary of PNC
Asset  Management  Group,  Inc., the holding company for PNC's asset  management
businesses and an Administration Agreement with Princeton  Administrators,  L.P.
(the  "Administrator"),  an indirect wholly-owned  subsidiary of Merrill Lynch &
Co., Inc.
 
   The  investment  advisory  fee paid to the  Adviser  is  computed  weekly and
payable  monthly at an annual  rate of 0.35% of the Trust's  average  weekly net
investment  assets.  The  administration  fee paid to the  Administrator is also
computed  weekly and  payable  monthly at an annual rate of 0.10% of the Trust's
average weekly net investment assets.

   Pursuant to the agreements,  the Adviser provides  continuous  supervision of
the investment  portfolio and pays the compensation of officers of the Trust who
are  affiliated  persons of the Adviser.  The  Administrator  pays occupancy and
certain  clerical and accounting  costs of the Trust.  The Trust bears all other
costs and expenses.

NOTE 3. PORTFOLIO POLICIES
Purchases  and  sales  of  x  investment   securities,   other  than  short-term
investments,  for the year ended  December 31, 1997  aggregated  $4,632,406  and
$4,867,940,   respectively.


                                       10


<PAGE>


     The federal  income tax basis of the Trust's  investments  at December  31,
1997 was  substantially  the same as the  basis  for  financial  reporting,  and
accordingly,  unrealized appreciation was $25,482,347 (on both a gross and a net
basis).

NOTE 4. CAPITAL 

There are 200 million shares of $.01 par value common stock  authorized.  Of the
11,257,093  common shares  outstanding  at December 31, 1997,  the Adviser owned
7,093  shares.  As of  December  31,  1997,  there were 3,420  preferred  shares
outstanding as follows: Series F28-1,710 and Series F7-1,710.

   The Trust may classify or reclassify any unissued shares of common stock into
one or more  series  of  preferred  stock.  On  November  23,  1992,  the  Trust
reclassified  1,710 shares of common stock and issued 2 series of Auction Market
Preferred Stock ("Preferred Stock") as follows:  Series F28--855 shares,  Series
F7--855 shares. The Preferred Stock has a liquidation value of $25,000 per share
plus any accumulated but unpaid dividends. On May 16, 1995 shareholders approved
a proposal to split each share of the Trust's  Auction Rate Municipal  Preferred
Stock  into two  shares  and  simultaneously  reduce  each  share's  liquidation
preference from $50,000 to $25,000 plus any  accumulated  but unpaid  dividends.
The stock split occurred on July 24, 1995.

   Dividends on Series F7 are  cumulative  at a rate which is reset every 7 days
based on the results of an auction.  Dividends on Series F28 are also cumulative
at a rate  which is reset  every 28 days  based on the  results  of an  auction.
Dividend rates ranged from 2.90% to 5.00% for the year ended December 31, 1997.

   The Trust may not declare dividends or make other  distributions on shares of
common  stock or purchase  any such  shares if, at the time of the  declaration,
distribution  or  purchase,  asset  coverage  with  respect  to the  outstanding
Preferred Stock would be less than 200%.

   The Preferred  Stock is redeemable at the option of the Trust, in whole or in
part, on any dividend  payment date at $25,000 per share plus any accumulated or
unpaid dividends whether or not declared. The Preferred Stock is also subject to
mandatory  redemption  at  $25,000  per  share  plus any  accumulated  or unpaid
dividends,  whether or not  declared  if certain  requirements  relating  to the
composition  of the  assets  and  liabilities  of the  Trust as set forth in the
Articles of Incorporation are not satisfied.

   The holders of  Preferred  Stock have voting  rights  equal to the holders of
common stock (one vote per share) and will vote  together with holders of shares
of common stock as a single class. However,  holders of Preferred Stock are also
entitled to elect two of the Trust's  directors.  In  addition,  the  Investment
Company Act of 1940 requires that along with approval by stockholders that might
otherwise  be  required,  the  approval  of the  holders  of a  majority  of any
outstanding  preferred shares, voting separately as a class would be required to
(a) adopt any plan of  reorganization  that would adversely affect the Preferred
Stock, and (b) take any action requiring a vote of security holders,  including,
among other  things,  changes in the Trust's  subclassification  as a closed-end
investment company or changes in its fundamental investment restrictions.


NOTE 5. DIVIDENDS
Subsequent to December 31, 1997,  the Board of Directors of the Trust declared a
dividend  from  undistributed  earnings of  $0.07125  per common  share  payable
January 31, 1998 to shareholders of record on January 15, 1998.

   For the period  January 1, 1998 to January 31,  1998,  dividends  declared on
Preferred Stock totalled $264,573 in aggregate for the two outstanding Preferred
Stock series.

- --------------------------------------------------------------------------------

The Shareholders and Board of Directors of
The BlackRock New York Insured Municipal 2008 Term Trust Inc.:

We have audited the accompanying statement of assets and liabilities,  including
the portfolio of investments,  of The BlackRock New York Insured  Municipal 2008
Term Trust  Inc.,  as of  December  31,  1997,  and the  related  statements  of
operations for the year then ended, and of changes in net investment  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, 1997 by correspondence with the custodian.  An audit also includes assessing
the accounting principles used and significant estimates made by Management,  as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

In our opinion,  such  financial  statements  and financial  highlights  present
fairly, in all material  respects,  the financial  position of The BlackRock New
York Insured Municipal 2008 Term Trust Inc. as of December 31, 1997, the results
of its  operations,  the changes in its net investment  assets and the financial
highlights  for the  respective  stated  periods,  in conformity  with generally
accepted accounting principles.

- --------------------------------------------------------------------------------
                           DIVIDEND REINVESTMENT PLAN
- --------------------------------------------------------------------------------

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

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

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

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

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

      THE BLACKROCK NEW YORK INSURED MUNICIPAL 2008 TERM TRUST INC.
                               INVESTMENT SUMMARY
- --------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE

      The Trust's investment  objective is to provide current income exempt from
federal  income  tax,  New York State and New York City income tax and to return
$15 per share (the initial  public  offering price per share) to investors on or
about December 31, 2008

WHO MANAGES THE TRUST?

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

WHAT CAN THE TRUST INVEST IN?

      The Trust intends to invest at least 80% of total assets in a portfolio of
New York municipal obligations insured as to the timely payment of principal and
interest.  The  Trust  may  invest  up to 20% in  uninsured  New York  municipal
obligations  which are rated Aaa by Moody's or AAA by S&P, or are  determined by
the Adviser to be of comparable credit quality  (guaranteed,  escrowed or backed
in trust).

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 ($15 per
share) at maturity.  The Trust will implement a conservative  strategy that will
seek to  closely  match the  maturity  of the assets of the  portfolio  with the
future  return of the  initial  investment  at the end of 2008.  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, if any, 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 portfolio of
New York municipal obligations and retaining a small amount of income each year.

     In  addition  to seeking  the return of the  initial  offering  price,  the
Adviser also seeks to provide current income exempt from federal income tax, New
York State and New York City income tax 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 35%
of the  total  assets)  to  enhance  the  income of the  portfolio.  In order to
maintain  competitive  yields as the Trust approaches  maturity and depending on
market  conditions,  the Adviser will attempt to purchase  securities  with call
protection  or  maturities  as close to the Trust's  maturity  date as possible.
Securities with call protection should provide the portfolio with some degree of
protection against  reinvestment risk during times of lower prevailing  interest
rates. Since the Trust's primary goal is to return the initial offering price at
maturity,  any cash that the Trust  receives  prior to its maturity date 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. If
market conditions, such as high interest rate volatility, force a choice between
current  income and  risking  the return of the initial  offering  price,  it is
likely that the return of the initial offering price will be emphasized.

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 Trust through the Trust's transfer agent,  State Street
Bank and Trust Company. Investors who wish to hold shares in a brokerage account
should check with their financial  advisor to determine  whether their brokerage
firm offers dividend reinvestment services.

LEVERAGE CONSIDERATIONS IN A TERM TRUST

      Under current market  conditions,  leverage increases the income earned by
the  Trust.  The Trust  employs  leverage  primarily  through  the  issuance  of
preferred stock.  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 35% 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 Trust in a
declining rate environment,  but can cause net assets to decline faster than the
market in a rapidly  rising rate  environment.  BlackRock's  portfolio  managers
continuously  monitor and  regularly  review the Trust's use of leverage and the
Trust may reduce,  or unwind,  the amount of leverage  employed should BlackRock
consider that reduction to be in the best interests of the shareholders.

SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO TERM TRUSTS

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

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

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

LEVERAGE.  The Trust utilizes  leverage  through the issuance of preferred stock
which involves  special risks.  The Trust's net asset value and market value may
be more volatile due to its use of leverage.

MARKET PRICE OF SHARES.  The shares of closed-end  investment  companies such as
the Trust trade on the New York Stock  Exchange  (NYSE symbol:  BLN) 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.

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. Investing in these securities involves special risks.

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

MUNICIPAL OBLIGATIONS.  Municipal obligations include debt obligations issued by
states,  cities, and local authorities,  and possessions and certain territories
of the United States to obtain funds for various public purposes,  including the
construction of public  facilities,  the refinancing of outstanding  obligations
and the obtaining of funds for general operating expenses and for loans to other
public  institutions  and  facilities.  The value of municipal  debt  securities
generally  varies  inversely with changes in prevailing  market  interest rates.
Depending  on the amount of call  protection  that the  securities  in the Trust
have, the Trust may be subject to certain  reinvestment risks in environments of
declining interest rates.

ALTERNATIVE  MINIMUM TAX (AMT).  The Trust may invest in  securities  subject to
AMT. The Trust currently holds no securities that are subject to AMT.

          THE BLACKROCK NEW YORK INSURED MUNICIPAL 2008 TERM TRUST INC.
                                    GLOSSARY
- --------------------------------------------------------------------------------


CLOSED-END  FUND:             Investment  vehicle which initially offers a fixed
                              number of shares and  trades on a stock  exchange.
                              The fund invests in a portfolio of  securities  in
                              accordance with its stated  investment  objectives
                              and policies.

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

DIVIDEND:                     Income  generated by securities in a portfolio and
                              distributed to shareholders after the deduction of
                              expenses.  This Trust  declares and pays dividends
                              to common shareholders on a monthly basis.

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

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

NET ASSET  VALUE  (NAV):      Net asset value is the total  market  value of all
                              securities  and other  assets  held by the  Trust,
                              plus income accrued on its investments,  minus any
                              liabilities including accrued expenses, divided by
                              the total number of outstanding  shares. It is the
                              underlying value of a single share on a given day.
                              Net asset value for the Trust is calculated weekly
                              and  published  in BARRON'S and THE NEW YORK TIMES
                              on  Saturday  or  THE  WALL  STREET  JOURNAL  each
                              Monday.

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

PREREFUNDED BONDS:            These  securities  are   collateralized   by  U.S.
                              Government securities which are held in escrow and
                              are used to pay  principal and interest on the tax
                              exempt  issue and  retire  the bond in full at the
                              date indicated, typically at a premium to par.

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


      BlackRock Financial Management Inc. (BlackRock) is a registered investment
adviser which specializes in managing high quality fixed income securities, both
taxable and tax exempt. BlackRock currently manages approximately $55 billion of
assets across the government,  mortgage,  corporate and municipal sectors. These
assets are managed on behalf of  institutional  and  individual  investors in 21
closed-end  funds traded  either on the New York Stock  Exchange or the American
Stock Exchange, several open-end funds and over 125 institutional clients in the
United States and overseas.

      BlackRock  was  formed in April  1988 by fixed  income  professionals  who
sought to create an asset management firm  specializing in managing fixed income
securities for individuals and  institutional  investors.  The  professionals at
BlackRock have extensive experience creating, analyzing and trading a variety of
fixed income instruments,  including the most complex structured securities.  In
fact, individuals at BlackRock are responsible for many of the major innovations
in  the  mortgage-backed  and  asset-backed  securities  market,  including  the
creation of the 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
significant  emphasis  it  places on the  development  of  propriety  analytical
capabilities.  A quarter of the professionals at BlackRock work full-time in the
design,  maintenance  and use of such systems  which are otherwise not generally
available to  investors.  BlackRock's  propriety  analytical  tools are used for
evaluating,  investing in and designing  investment  strategies and portfolio of
fixed  income  securities,   including  mortgage   securities,   corporate  debt
securities or tax-exempt securities and a variety of hedging instruments.

      BlackRock has developed  investment  products  which respond to investors'
needs and has been  responsible  for several  major  innovations  in  closed-end
funds.  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 AAAf  rating by  Standard & Poor's,  and the first
closed-end  fund to invest  primarily in North American  Government  securities.
BlackRock's  closed-end funds currently have dividend  reinvestment  plans which
are  designed  to  provide  an  ongoing  source of  demand  for the stock in the
secondary market. BlackRock manages a ladder of alternative investment vehicles,
with each fund 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
you may have about your  BlackRock  funds and thank you for the continued  trust
you place in our abilities.
