              THE BLACKROCK INSURED MUNICIPAL 2008 TERM TRUST INC.
                          ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISOR
-------------------------------------------------------------------------------


                                                                January 31, 2001


Dear Shareholder:

   The continued trend of economic growth boosted by strong consumer confidence,
a tight  labor  market and  inflation  concerns  caused the  Federal  Reserve to
aggressively  tighten during the first five months of the year. As a result, the
Fed raised the  discount  rate to 6.50% during the year in an attempt to achieve
its objective of engineering a "soft  landing" for the explosive  U.S.  economy.
The third quarter of 2000 saw a sharp decline in market expectations for further
Fed tightenings amidst evidence of significant  deceleration in growth,  peaking
inflation  pressures  and a sharp  reversal in the stock  market  wealth  effect
globally.

   During the fourth quarter, investor hopes for a "soft landing" quickly turned
into fears of a recession as the U.S. economy rapidly deteriorated.  The effects
of tighter  monetary and fiscal  conditions,  along with higher  energy  prices,
combined to pull down domestic growth rates. As market expectations transitioned
from Fed  tightening  to a  significant  Fed easing,  high quality  fixed-income
assets, led by the Treasury market, produced strong double-digit returns.

   The Federal  Reserve has expressed  great  concern over the  economy's  quick
downturn.  After removing their tightening bias at their December  meeting,  the
FOMC acted with an aggressive 50 basis point intra-meeting  reduction of the Fed
Funds rate on January 3, 2001 and another 50 basis point cut at their meeting on
January  31,  2001.  While we think  that the  Fed's  actions  could  provide  a
temporary lift to U.S. investor and consumer sentiment, our intermediate outlook
for the  economy  remains  cautious.  The  potential  for tax cuts in 2001  adds
further  uncertainty to the economic forecast.  Given that the primary effect of
the  stimulus  from a tax cut would  occur in 2002 and beyond,  monetary  policy
stimulus will have a greater effect on the U.S.  economy near term.  Considering
only moderate economic recovery in Europe and anemic growth in Japan, we believe
that enough  distress  exists within the economic  system to warrant  additional
easing by the Fed over the coming months.

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

Sincerely,

Dear Shareholder:

   We are pleased to present the audited annual report for The BlackRock Insured
Municipal  2008 Term Trust Inc. ("the Trust") for the fiscal year ended December
31, 2000.  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  diversified,  actively  managed  closed-end  bond fund  whose
shares  are traded on the New York Stock  Exchange  under the symbol  "BRM." The
Trust's  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 current income exempt from regular federal income tax. The Trust seeks
to achieve this  objective by investing in high credit quality ("AAA" or insured
to "AAA") tax-exempt general obligation and revenue bonds issued by city, county
and state municipalities throughout the United States.

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

THE FIXED INCOME MARKETS

   The rapid  expansion  of U.S.  GDP  witnessed  throughout  much of the period
finally slowed dramatically in the third and fourth quarter.  After expanding at
nearly a 6.0% annualized rate in the first half of the year, growth in the third
quarter slowed to 3.0%.  Higher oil prices and declines in global equity markets
led to declines in consumer spending,  residential  investment and manufacturing
activity. The Federal Reserve raised the discount rate by 0.25% at each of their
meetings in November 1999, February 2000, and March 2000 and raised the discount
rate by 0.50% in May 2000 to bring the year end discount rate to 6.50%. At their
meeting in December 2000, the Federal  Reserve left the discount rate unchanged,
although it moved towards an easing bias,  due to an increasing  probability  of
economic weakness in the foreseeable future.

   Treasury  yields  were  inverted  for much of the  year.  Yields  rose on the
short-end of the yield curve in response to the Fed's  increases in the discount
rate, while yields on the long-end declined below the short-end, particularly in
reaction to the  announcement  that the  Treasury  would buy back $30 billion of
Treasuries  with  maturities  ranging from 10 to 30 years. In the second half of
the period,  weakening  stock markets and signs of slowing growth all caused the
bond  market  to  price in a  neutral  Federal  Reserve.  This  shift in  market
sentiment caused significant yield curve  disinversion  during the third quarter
of 2000, as yields on the short-end fell relative to yields on the long-end.  In
the last two months of 2000, the Treasury  market rallied  significantly  on the
short-end  of  the  curve,   and  in  December  the  yield  curve  regained  its
characteristic  upward slope.  For the annual  period,  the yield on the 10-year
Treasury fell from 6.44% on December 31, 1999 to 5.11% on December 31, 2000.

   During the fourth quarter, the municipal yield curve flattened by 12 bps with
2-year  yields  declining  by 35 bps while  30-year  yields  declined by 47 bps.
Throughout this time frame,  municipals  continued to outperform  taxable spread
product while  underperforming  versus  Treasuries.  Municipals  benefited  from
retail's  continued  efforts to diversify  out of equities and into fixed income
investments  as  evidenced  by the mutual  fund  industry  finally  experiencing
positive  cash  flow  in  the  municipal   sector  during  the  fourth  quarter.
Institutional  demand for municipal  securities  has also increased as investors
are  looking  for  attractive  after tax yields  versus  Treasuries  without the
inherent credit risk associated with corporate bonds.

THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY

   The Trust's  portfolio is actively  managed to diversify  exposure to 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 and
coupons.  Additionally,  the Trust  emphasizes  securities  whose maturity dates
match the termination date of the Trust.

   Over the year, trading activity in the Trust remained relatively low, as many
of the  securities in the Trust's  portfolio  continued to trade at prices above
where  they were  purchased.  As  trading  activity  that  results  in the Trust
realizing  a capital  gain  could  require a  taxable  distribution,  as well as
reducing the income  generating  capacity of the Trust,  we remain  reluctant to
realize capital gains at this time. At present,  we are confident that the Trust
is on schedule to achieve its primary investment  objective of returning $15 per
share upon termination and will continue to seek investment opportunities in the
municipal market.

   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 monthly income.  At the end of
the year, the Trust's leverage amount was approximately 37% of total assets.

THE BLACKROCK INSURED
MUNICIPAL 2008 TERM TRUST INC.
NOTES TO FINANCIAL STATEMENTS
-------------------------------------------------------------------------------
NOTE 1. ORGANIZATION &                                The   BlackRock   Insured
ACCOUNTING                                            Municipal  2008 Term Trust
POLICIES                                              Inc. (the   "Trust"),  was
orga nized in Maryland on August 7, 1992 as a diversified, closed-end management
investment company.  The Trust's investment objective is to manage a 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 income tax. The ability of issuers of debt  securities held by the Trust
to meet their  obligations  may be  affected  by  economic  developments  in the
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 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 bond dealers,  market transactions in comparable  securities and
various  relationships  between  securities in  determining  values.  Short-term
securities  are valued at amortized  cost.  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.

     SECURITIES TRANSACTIONS AND INVESTMENT INCOME:  Securities transactions are
recorded  on the trade  date.  Realized  and  unrealized  gains and  losses  are
calculated  on the  identified  cost basis.  Interest  income is recorded on the
accrual  basis and the Trust  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
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.
Dividends and distributions to preferred shareholders are accrued and determined
as described in Note 4.

     ESTIMATES:  The  preparation  of financial  statements in  conformity  with
accounting  principles  generally  accepted  in the  United  States  of  America
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.

     DEFERRED  COMPENSATION PLAN: Under a deferred compensation plan approved by
the Board of Directors on February 24, 2000,  non-interested Directors may elect
to defer  receipt of all or a portion  of their  annual  compensation.

     Deferred  amounts  earn a return  for the  Directors  as though  equivalent
dollar  amounts had been  invested  in common  shares of other  BlackRock  funds
selected by the Directors.  This has the same economic  effect for the Directors
as if the  Directors had invested the deferred  amounts in such other  BlackRock
funds.

     The deferred  compensation  plan is not funded and  obligations  thereunder
represent  general unsecured claims against the general assets of the Trust. The
Trust may, however,  elect to invest in common shares of those funds selected by
the Directors in order to match its deferred compensation obligations.

NEW ACCOUNTING POLICIES:  The Trust will adopt the provisions of the AICPA Audit
and Accounting Guide for Investment Companies, as revised,  effective for fiscal
years  beginning  after  December  15, 2000.  As required,  the Trust will begin
amortizing discounts on debt securities effective January 1, 2001. Prior to this
date,  the  Trust  amortized  premiums  and  original  issue  discount  on  debt
securities but did not amortize market discount.  The cumulative  effect of this
accounting  change will have no impact on the total net assets of the Trust. The
impact of this accounting  change is anticipated to have an immaterial effect on
the  financial  statements  and will result in an increase to cost of securities
and a corresponding decrease in net unrealized appreciation, based on securities
held as of December 31, 2000.

NOTE 2. AGREEMENTS                                  The Trust has an Investment
                                                    Advisory   Agreement   with
BlackRock Advisors, Inc., (the "Advisor"), which is a wholly-owned subsidiary of
BlackRock,  Inc., which in turn is an indirect majority-owned  subsidiary of PNC
Financial  Services Group, Inc. The Trust has an  Administration  Agreement with
Princeton Administrators,  L.P. (the "Administrator"),  an indirect wholly-owned
affiliate of Merrill Lynch & Co., Inc.


                                       12



     The  investment  advisory  fee paid to the Advisor 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 Advisor provides continuous supervision of
the investment  portfolio and pays the compensation of officers of the Trust who
are  affiliated  persons of the Advisor.  The  Administrator  pays occupancy and
certain  clerical and accounting  costs of the Trust.  The Trust bears all other
costs and expenses.

NOTE 3. PORTFOLIO                                       Purchases  and sales of
SECURITIES                                              investments, other than
short-term  investments,  for the  year  ended  December  31,  2000,  aggregated
$81,228,238 and $19,385,536, respectively.

     The federal  income tax basis of the Trust's  investments  at December  31,
2000, was $665,088,606,  and accordingly,  gross and net unrealized appreciation
was $48,564,476.

     For federal income tax purposes,  the Trust had a capital loss carryforward
at December 31, 2000 of  approximately  $53,000 of which  $34,000 will expire in
2007 and $19,000 will expire in 2008. Accordingly,  no capital gain distribution
is expected  to be paid to  shareholders  until net gains have been  realized in
excess of such amounts.

NOTE 4. CAPITAL                                    There are 200 million shares
                                                   of  $.01  par  value  common
stock  authorized.  The Trust may classify or reclassify any unissued  shares of
common  stock into one or more  series of  preferred  stock.  Of the  27,207,093
common shares  outstanding at December 31, 2000, the Advisor owned 7,093 shares.
As of December 31,  2000,  there were 10,840  preferred  shares  outstanding  as
follows:  Series  T28--2,060,  Series R28--2,060,  Series T7--4,660,  and Series
R7--2,060, which includes 2,600 shares of Series T7 issued on March 10, 2000.

     On March 10, 2000, the Trust  reclassified 2,600 shares of common stock and
issued an additional 2,600 shares of Series T7 preferred shares.  The additional
shares  issued have  identical  rights and  features of the  existing  Series T7
preferred  shares.   Estimated  offering  costs  of  $317,160  and  underwriting
discounts  of  $650,000  have been  charged to paid-in  capital in excess of the
common shares.

     Dividends on Series T7 and R7 are cumulative at a rate which is reset every
7 days  based  on the  results  of an  auction.  Dividends  on  Series  T28  are
cumulative  at a rate which is reset  every 28 days  based on the  results of an
auction.  Series R28 paid dividends monthly at a rate established at the initial
offer- ing through May 17, 1994. Thereafter,  rates on Series R28 reset every 28
days based on the results of an  auction.  Dividend  rates  ranged from 2.40% to
5.90%  during  the year  ended  December  31,  2000.

     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 stock,  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, 2000, the Board of
Directors  of the Trust  declared  a dividend  from  undistributed  earnings  of
$0.06625 per common share payable, February 1, 2001 to shareholders of record on
January 16, 2001.

     For the period  January 1, 2001 to January 31, 2001  dividends  declared on
preferred  shares  totalled  $920,230  in  aggregate  for the  four  outstanding
preferred share series.

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

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

We have audited the accompanying statement of assets and liabilities,  including
the portfolio of investments, of The BlackRock Insured Municipal 2008 Term Trust
Inc.,  (the  "Trust") as of December  31,  2000,  and the related  statement  of
operations for the year then ended, and of changes in net assets for each of the
two years in the period then ended and the financial  highlights for each of the
five years in the period then ended.  These  financial  statements and financial
highlights are the responsibility of the Trust's management.  Our responsibility
is to express an opinion on these financial  statements and financial highlights
based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  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, 2000 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,  the  financial  statements  and  financial  highlights  present
fairly,  in all  material  respects,  the  financial  position of The  BlackRock
Insured  Municipal 2008 Term Trust Inc. as of December 31, 2000, and the results

were federal tax-exempt interest dividends.

     For purposes of preparing your annual federal income tax return, you should
report the amounts as reflected on the  appropriate  form 1099-DIV or substitute
1099 DIV.

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

     Pursuant to the Trust's  Dividend  Reinvestment  Plan (the "Plan"),  common
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.

     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.

     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.

               THEBLACKROCK INSURED MUNICIPAL 2008 TERM TRUST INC.
                               INVESTMENT SUMMARY
--------------------------------------------------------------------------------


THE TRUST'S INVESTMENT OBJECTIVE:

The BlackRock  Insured  Municipal2008  Term Trust's  investment  objective is to
provide  current income exempt from regular Federal 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  Advisors,  Inc.  (the  "Advisor")  is  an  SEC-registered  investment
advisor.  As of December 31,  2000,  the Advisor and its  affiliates  (together,
"BlackRock")  managed $204 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 managed twenty-one  closed-end funds that are traded on either the New
York or American stock  exchanges,  and a $26 billion family of open-end  funds.
BlackRock's 301 clients are domiciled in the United States and overseas.

WHAT CAN THE TRUST INVEST IN?

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

WHAT IS THE ADVISOR'S INVESTMENT STRATEGY?

The Advisor will seek to meet the Trust's  investment  objective by managing the
assets of the Trust so as to return the initial  offering  price ($15 per share)
at maturity.  The Advisor will implement a conservative  strategy that will seek
to closely match the maturity or call  provisions 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 or called,
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 municipal  obligations  and retaining a small portion of its income
each year. In addition to seeking the return of the initial  offering price, the
Advisor also seeks to provide  current income exempt from regular Federal 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 to enhance the income of the  portfolio.  In
order to  maintain  competitive  yields as the  Trust  approaches  maturity  and
depending on market conditions,  the Advisor will attempt to purchase securities
with call  protection  or  maturities  as close to the Trust's  maturity date as
possible. Securities with call protection should provide the portfolio with some
degree of protection against  reinvestment risk during times of lower prevailing
interest rates. Since the Trust's primary goal is to return the initial offering
price at maturity,  any cash that the Trust  receives prior to its maturity date
will be  reinvested  in  securities  with  maturities  which  coincide  with the
remaining  term of the  Trust.  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 interest rate volatility,  force a choice
between current income and risking the return of the initial  offering price, it
is likely 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  common  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 first 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.

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

SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO TERM TRUSTS

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

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

DIVIDEND CONSIDERATION. 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:  BRM) 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 only to do so to a
limited extent. An investment 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.

                                    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.  The 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  common shares.  It is the underlying value of a single common share
                        on a given  day.  Net  asset  value  for the  Trust  is  calculated  weekly  and
                        published in BARRON'S on Saturday and THE WALL STREET JOURNAL on Monday.

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

PRE-REFUNDED 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.
