                       SEMI-ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISOR
--------------------------------------------------------------------------------
                                                                   July 31, 2002
Dear Shareholder:

      The  semi-annual  period ended June 30, 2002,  saw general  turmoil in the
equity markets. Bond markets,  particularly municipal securities, proved to be a
viable shelter from unstable economic  conditions and experienced strong inflows
throughout the period.  Municipal bonds outperformed  Treasuries returning 4.64%
versus 3.61%  respectively  as measured by the Lehman  Brothers  Municipal  Bond
Index* and the Lehman  Brothers  Treasury  Index** for the six months ended June
30, 2002.

      The first half of 2002 was markedly  different from the last six months of
2001, as the Federal  Reserve Board (the "Fed") left interest  rates  unchanged.
After a 225 basis  point  decline in  interest  rates  during the latter half of
2001,  and the  uncertainty  of the economic  recovery in the first half of this
year,  the Fed  remained  cautious  about  the  state of the  economy.  Fears of
inflation remained subdued,  allowing the Fed to remain on hold and maintain the
lowest interest rates in decades.

      The past six months  also saw a 20%  increase  in new  municipal  issuance
totaling  $162  billion,  as compared  to the same time  period last year.  Both
retail and institutional investment in municipals remained high and continued to
drive  performance  as  investors  sought  lower  volatility  alternatives  with
attractive  taxable  equivalent  yields.   While  economic  indicators  remained
positive  during  the  period,   the  instability  of  the  equity  and  capital
markets--as a result of corporate  governance  and accounting  issues,  fears of
renewed  terrorist  acts  and  geopolitical   instability--weighed  on  investor
confidence, an integral component of economic recovery.

      The  volatility,  which continues to be seen throughout all sectors of the
market,  can be  disconcerting  for investors.  We encourage you to consult with
your financial  advisor to help establish a strategy that best fits your overall
goals and risk tolerance.

      The semi-annual  report  includes a summary of market  conditions over the
last six months,  a review of the strategy  employed by your  Trust's  portfolio
managers,  the  Trust's  unaudited  financial  statements  and a listing  of the
portfolio's  holdings.  We thank you for your continued  confidence in BlackRock
and the opportunity to help you achieve your long-term investment goals.

Sincerely,


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

Dear Shareholder:

     We are pleased to present the first  unaudited  semi-annual  report for the
BlackRock  Municipal 2018 Term Trust (the "Trust") for the six months ended June
30,  2002.  We would like to take this  opportunity  to review the change in the
Trust's  stock price and net asset value (NAV),  summarize  developments  in the
fixed income markets and discuss recent portfolio management activity.

     The Trust is a diversified  closed-end bond fund whose shares are traded on
the New York Stock  Exchange  under the symbol  "BPK."  The  Trust's  investment
objectives  are to provide  current  income that is exempt from regular  Federal
income tax and to return $15 per share (an amount  equal to the Trust's  initial
public  offering  price) to investors on or about  December 31, 2018.  The Trust
will invest at least 80% of its total assets in municipal bonds that at the time
of investment are investment  grade quality (rated "Baa" or "BBB" or better by a
major rating agency or of equivalent quality). The Trust may invest up to 20% of
its  total  assets  in  municipal  bonds  that  at the  time of  investment  are
non-investment  grade  (rated  "Ba/BB"  or "B" by a major  rating  agency  or of
equivalent quality).

     The table below summarizes the changes in the Trust's share price and NAV:

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

THE FIXED INCOME MARKETS

     Economic performance was mixed during the semi-annual period ended June 30,
2002, as volatility and instability were prevalent throughout all sectors of the
market.  The U.S. economy showed signs of recovery,  but mixed economic data and
dismal  performance  in the equity  markets  caused a massive  unwinding  of Fed
tightening  expectations.  Structural  imbalances  in the  U.S.  economy  became
evident  and  the  effects  of  the  short-term  stimulus  post  September  11th
diminished,  causing the Fed to remain on hold and leave the Federal  Funds rate
unchanged at 1.75%. Positive economic data included a rise in first quarter 2002
GDP of 6.1%, the fastest rate in two years,  strong  manufacturing data, an 8.4%
rise in first  quarter  2002  productivity  and the  Consumer  Confidence  Index
advancing   from  year-end   levels.   Low  inventory   levels  should   support
manufacturing  data,  but we are  skeptical  about  the  continued  strength  of
consumer  demand,  which is  essential  to a sustained  economic  recovery.  The
long-term  sustainability  of the highly  leveraged  consumer  remains a pivotal
issue to the strength of the economic recovery.  Although fundamentals support a
recovery,  declining equities and a plummeting dollar continue to erode investor
confidence.  We remain uncertain that a near-term business  investment  recovery
will  materialize,  as pricing power remains weak. While second quarter weakness
may be  overstated,  the likely  outcome is one of several  quarters  of sub-par
growth in the 2.5%-3.0% range.

     Year-to-date, rates have fallen across the yield curve. The Treasury market
returned 3.61% during the period,  posting  exceptionally strong months in April
and June as risk aversion dominated the markets.  Over the course of the period,
the yield curve steepened in reaction to mixed economic data and a proliferation
of negative headlines in the corporate sector. Looking ahead, the budget surplus
of 2001 is unlikely to be sustained  due to anemic tax revenues and a sharp rise
in defense spending,  which should result in larger auction sizes.  However, the
allowable debt limit set by Congress will soon be reached,  possibly leading the
Treasury  to pursue  additional  methods  of  financing  until it can  return to
regular  auctions.  As of June 30, 2002, the 10-year Treasury was yielding 4.80%
versus 5.05% on December 31, 2001.

     On a tax-adjusted basis,  municipal bonds outperformed the taxable domestic
bond market for the semi-annual period ended June 30, 2002,  returning 7.55% (as
measured by the Lehman  Municipal  Bond Index at a tax bracket of 38.6%)  versus
3.79% for the Lehman  Aggregate  Index.  Retail  investment  has reached  record
highs, as investors  searched for a lower  volatility asset class providing high
after-tax  returns.  Institutional  demand has also remained strong and is being
fueled by increased profitability on the part of insurance companies, the search
for stable income and asset  allocation  trades away from segments of the market
experiencing  higher  volatility.  Over the  period,  strong  demand  was met by
significant new issuance as the first quarter of 2002 posted a 10% increase over
the same  period in 2001 and was the  largest  first  quarter  total on  record.
Through June, new

                                        2


bond issuance remained robust,  bringing total  year-to-date  issuance to nearly
$170 billion,  and is on pace to be the largest  issuance  year in history.  The
municipal yield curve remains  historically steep, as the short end of the curve
has  outperformed  Treasuries  over the recent  months while  longer  maturities
performed in line with their Treasury counterparts.

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.

     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.  At the
end of the period,  the Trust's leverage amount was  approximately  36% of total
assets.

BLACKROCK MUNICIPAL 2018 TERM TRUST
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
--------------------------------------------------------------------------------

NOTE 1: ORGANIZATION & ACCOUNTING POLICIES

The  BlackRock  Municipal  2018 Term  Trust (the  "Trust")  was  organized  as a
Delaware  business  trust  on  September  7,  2001 as a  diversified  closed-end
management  investment  company under the  Investment  Company Act of 1940.  The
Trust had no  transactions  until  October  18,  2001 when it sold 8,028  common
shares for $115,001 to BlackRock Advisors,  Inc. Investment operations commenced
on October 30, 2001. The Trust's  investment  objectives are to provide  current
income  that is exempt  from  regular  Federal  income tax and to return $15 per
common share to holders of common  shares on or about  December  31,  2018.  The
ability  of  issuers  of  debt  securities  held  by the  Trust  to  meet  their
obligations  may be affected  by  economic  developments  in certain  states,  a
specific  industry  or  region.  No  assurance  can be given  that  the  Trust's
investment objectives 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  selected under the  supervision of the
Trust's  Trustees.  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.  Short-term investments
may be 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 Trustees.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME:  Securities  transactions  are
recorded on trade date.  Realized and unrealized gains and losses are calculated
on the  identified  cost basis.  The Trust also  records  interest  income on an
accrual basis and amortizes  premium and accretes discount to interest income on
securities purchased using the interest method.

SEGREGATION:  In cases in which the  Investment  Company Act of 1940, as amended
and the interpretive positions of the Securities and Exchange Commission ("SEC")
require  that the  Trust  segregate  assets in  connection  with  certain  Trust
investments (e.g., when issued securities, reverse repurchase agree
ments  or  futures   contracts),   the  Trust  will,   consistent  with  certain
interpretive  letters issued by the SEC, designate on its books and records cash
or other  liquid  debt  securities  having a market  value at least equal to the
amount that would otherwise be required to be physically segregated.

FEDERAL  INCOME TAXES:  It is the Trust's  intention to elect to be treated as a
regular  investment  company  under the Internal  Revenue Code 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 these
estimates.

DEFERRED  COMPENSATION PLAN: Under a deferred  compensation plan approved by the
Board of Trustees on September  24, 2001,  non-interested  Trustees may elect to
defer receipt of all or a portion of their annual compensation.

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

   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 Trusts selected by
the Trustees in order to match its deferred compensation obligations.

CHANGE IN FINANCIAL  STATEMENT  CLASSIFICATION  FOR AMPS: In accordance with the
provisions  of  EITF  D-98,   "Classification   and  Measurement  of  Redeemable
Securities,"  effective for the current period,  the Trust has  reclassified its
Auction Market  Preferred Shares ("AMPS") outside of permanent equity in the net
assets  section  of the  Statement  of  Assets  and  Liabilities.  In  addition,
distributions to AMPS shareholders are now classified as a

                                       11


component of net assets resulting from operations on the Statement of Operations
and Changes in Net Assets and as a component of the investment operations in the
Financial  Highlights.  Prior period  amounts  presented  have been  restated to
conform  to this  period's  presentation.  This  change has no impact on the net
assets applicable to common shares of the Trust.

NOTE 2: AGREEMENTS

The Trust has an Investment  Advisory  Agreement with BlackRock  Advisors,  Inc.
(the  "Advisor"),  a  wholly  owned  subsidiary  of  BlackRock,  Inc.  BlackRock
Financial Management, Inc., a wholly owned subsidiary of BlackRock, Inc., serves
as  sub-advisor  to the Trust.  BlackRock,  Inc. is an indirect  majority  owned
subsidiary of PNC  Financial  Services  Group,  Inc. The  investment  management
agreement covers both investment advisory and administration services.

   The  investment  advisory  fee paid to the  Advisor  is  computed  weekly and
payable monthly at an annual rate of 0.40% of the Trust's average weekly managed
assets.  "Managed  assets"  means the total assets of the Trust  (including  any
assets  attributable to any preferred shares that may be outstanding)  minus the
sum of accrued  liabilities (other than debt representing  financial  leverage).
The total dollar  amounts paid to the Advisor by the Trust under the  Investment
Advisory  Agreement  for the six months ended June 30, 2002 and the period ended
December 31, 2001, were $716,331 and $179,716, respectively.

   Pursuant to the agreements,  the Advisor provides  continuous  supervision of
the investment portfolio, pays the compensation of officers of the Trust who are
affiliated persons of the Advisor, occupancy and certain clerical and accounting
costs of the Trust. The Trust bears all other costs and expenses,  which include
reimbursements to the Advisor for certain  operational support services provided
to the Trust.

   Pursuant to the terms of the custody  agreement,  the Trust receives earnings
credits from its custodian when positive cash balances are maintained, which are
used to offset custody fees. The earnings  credits for the six months ended June
30, 2002, were approximately $19,682.

NOTE 3: PORTFOLIO SECURITIES

Purchases and sales of investment securities, other than short-term investments,
for  the  six  months  ended  June  30,  2002,   aggregated   $140,828,196   and
$138,771,717, respectively.

   The Federal income tax basis of the Trust's  investments at June 30, 2002 was
$362,049,708, and accordingly, net unrealized appreciation was $2,880,639 (gross
unrealized appreciation--$5,747,092, gross unrealized depreciation--$2,866,453).

NOTE 4: CAPITAL

There are an  unlimited  number of $.001 par value common  shares of  beneficial
interest  authorized.  The Trust may classify or reclassify any unissued  common
shares into one or more series of preferred  shares.  Of the  15,908,028  common
shares outstanding at June 30, 2002, the Advisor owned 8,028 shares.

   Transactions  in common shares of  beneficial  interest for the period ending
December 31, 2001 were as follows:

   Shares issued in connection with
     initial public offering                                          14,708,028

   Offering costs of $462,000  incurred in connection with the Trust's  offering
of common  shares have been  charged to paid-in  capital in excess of par of the
common shares.

   On  December  14,  2001,  the  Trust  reclassified  5,504  common  shares  of
beneficial  interest and issued two series of Auction  Market  Preferred  Shares
("preferred shares") Series W7--2,752 and Series R7--2,752. The preferred shares
have a  liquidation  value of  $25,000  per share  plus any  accumulated  unpaid
dividends.  Underwriting  discounts of $1,376,000 and offering costs of $331,743
incurred in connection  with the preferred  share  offering have been charged to
paid-in capital in excess of par of the common shares.

   Dividends on Series W7 and Series R7 are  cumulative at a rate which is reset
every 7 days based on the  results of an  auction.  Dividend  rates  ranged from
1.25% to 1.60% during the six months ended June 30, 2002.

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

   The preferred  shares are 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  shares are 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
Declaration of Trust are not satisfied.

   The holders of  preferred  shares have voting  rights equal to the holders of
common shares (one vote per share) and will vote together with holders of common
shares as a single class.

                                       12


   However,  holders of preferred  shares are also  entitled to elect two of the
Trust's Trustees. In addition,  the Investment Company Act of 1940 requires that
along with  approval by  shareholders  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 shares 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 June 30,  2002,  the Board of  Trustees  of the Trust  declared a
dividend of $0.065 per common share payable  August 1, 2002 to  shareholders  of
record on July 15, 2002. For the period July 1, 2002 to July 31, 2002, dividends
declared  on  preferred  shares  totaled  $151,525,  in  aggregate  for  the two
outstanding preferred share series.

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

      Pursuant to the Trust's Dividend  Reinvestment  Plan (the "Plan"),  common
shareholders are  automatically  enrolled to have all distributions of dividends
and capital gains reinvested by EquiServe Trust Company, N.A. (the "Plan Agent")
in Trust shares pursuant to the Plan.  Shareholders who elect not to participate
in the Plan will  receive  all  distributions  in cash paid by check and  mailed
directly to the  shareholders  of record (or if the shares are held in street or
nominee name, then to the nominee) by the Plan 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 acquire shares for the participants' accounts,
by  the  purchase  of  outstanding  shares  on the  open  market  ("open  market
purchases"),  on the New York Stock  Exchange or  elsewhere.  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 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.  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.  There is no
direct service charge to participants in the Plan;  however,  the Trust reserves
the  right  to  amend  the Plan to  include  a  service  charge  payable  by the
participants.  All correspondence  concerning the Plan should be directed to the
Plan Agent at (800) 699-1BFM or 150 Royall Street, Canton, MA 02021.

                               INVESTMENT SUMMARY
--------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVES

The BlackRock  Municipal 2018 Term Trust's investment  objectives are to provide
current income that is exempt from regular  Federal income tax and to return $15
per common share to holders of common shares on or about December 31, 2018.

WHO MANAGES THE TRUST?

BlackRock  Advisors,  Inc. (the "Advisor")  manages the Trust.  The Advisor is a
wholly owned subsidiary of BlackRock,  Inc.  ("BlackRock"),  which is one of the
largest  publicly traded  investment  management firms in the United States with
$250 billion of assets under management as of June 30, 2002.  BlackRock  manages
assets on behalf of institutional and individual  investors  worldwide through a
variety of equity, fixed income,  liquidity and alternative investment products,
including the BlackRock Funds and BlackRock  Provident  Institutional  Funds. In
addition, BlackRock provides risk management and investment system services to a
growing number of  institutional  investors under the BlackRock  Solutions name.
Clients are served from the Company's  headquarters in New York City, as well as
offices in Boston,  Edinburgh,  Hong Kong, San Francisco,  Tokyo and Wilmington.
BlackRock is a member of The PNC Financial  Services  Group (NYSE:  PNC), and is
majority-owned by PNC and by BlackRock employees.

WHAT CAN THE TRUST INVEST IN?

Under normal  conditions,  the Trust expects to continue to manage its assets so
that at least 80% of its investments are rated at least  investment grade ("BBB"
by Standard & Poor's or "Baa" by Moody's Investor Services) and up to 20% of its
assets are rated below investment grade ("Ba/BB" or "B") or that are unrated but
deemed to be of comparable quality by the Advisor.

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 of ($15 per
share) on or about December 31, 2018. The Advisor will implement a 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 2018.
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
are 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 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 tax-exempt 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 may 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 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.


                                       16


HOWARE 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  its  transfer  agent,
EquiServe Trust Company,  N.A.  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 THE TRUST

The Trust employs leverage  primarily  through the issuance of preferred shares.
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  increases  the duration (or price  sensitivity  of the net assets with
respect to changes  in  interest  rates) of the  Trust,  which can  improve  the
performance of the Trust in a declining interest rate environment, but can cause
net assets to decline faster in a rapidly rising interest 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 THE TRUST

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

INVESTMENT  OBJECTIVES.  Although  the  objectives  of the Trust are to  provide
current income that is exempt from regular  Federal income tax and to return $15
per common  share to holders of common  shares on or about  December  31,  2018,
there can be no assurance that these objectives 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 shares,
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:  BPK) 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.

MUNICIPAL  OBLIGATIONS.  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.

HIGH  YIELD  RISK.  The Trust may  invest in high yield  bonds,  which  involves
additional risks,  including credit risk. The value of high yield, lower quality
bonds is affected by the  creditworthiness  of the issuers of the securities and
by general  economic and  specific  industry  conditions.  Issuers of high yield
bonds are not as strong  financially  as those with higher credit  ratings.  The
Trust's  investment in lower grade  securities  will expose the Trust to greater
risk than if the Trust owned only higher grade securities.

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.

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 Trustees and may have the effect of depriving  shareholders  of
an  opportunity  to sell their shares at a premium above the  prevailing  market
price.

ALTERNATIVE  MINIMUM TAX (AMT).  The Trust may invest in  securities  subject to
alternative minimum tax.

                                    GLOSSARY
--------------------------------------------------------------------------------

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

DISCOUNT:                          When a  Trust's  net asset  value is  greater
                                   than its market  price,  the Trust 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:             Common  shareholders  may have all  dividends
                                   and    distributions    of   capital    gains
                                   automatically   reinvested   into  additional
                                   shares of the Trust.

MARKET PRICE:                      Price per share of a security  trading in the
                                   secondary  market.  For a  closed-end  Trust,
                                   this is the  price at which  one share of the
                                   Trust  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,   including   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 Trust's  market  price is greater than
                                   its net asset value,  the Trust 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  to
                                   retire   the   bond  in  full  at  the   date
                                   indicated, typically at a premium to par.
