                                                                   July 31, 1998


Dear Shareholder:

      Domestic  bonds  provided  investors  with modest total returns during the
past six months,  as interest rates generally  fell.  Supporting the bond market
was favorable inflation news and the belief that the Federal Reserve is unlikely
to raise short-term interest rates in the immediate future.

      U.S.  economic  growth has slowed of late after a robust first  quarter of
1998.  We  expect  the  fallout  from the  Asian  fiscal  crisis  to  quash  any
significant  rebound in U.S.  growth  for the  remainder  of the year.  While we
expect  that  interest  rates  will  be  fairly  stable  in the  near-term,  our
longer-term  outlook  for the  bond  market  remains  optimistic,  based  on the
fundamentally  favorable  backdrop of low  inflation,  a currently high level of
real yields, and declining Treasury borrowing.

      As you may know, the five investment  management  firms that comprised the
PNC Asset  Management  Group have  consolidated  under  BlackRock,  resulting in
BlackRock Inc., a $119 billion money  management  firm. 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  comments from your Trust's  managers  regarding the
markets and  portfolio  in addition to the Trust's  financial  statements  and a
detailed  portfolio listing.  We thank you for your continued  investment in the
Trust.

Sincerely,

Dear Shareholder:

      We are pleased to present the semi-annual report for The BlackRock Florida
Insured Municipal 2008 Term Trust ("the Trust") for the six months ended June 30
1998. 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 income tax and Florida intangible  personal property
tax.  The Trust seeks to achieve  this  objective  by  investing  in high credit
quality ("AAA" or insured to "AAA") Florida  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 period:

THE FIXED INCOME MARKETS

      After an extremely  strong first  quarter of 1998,  U.S.  economic  growth
slowed during the past three months.  Despite the strong  economic growth of the
past year,  inflation  stayed  surprisingly  subdued.  One  explanation  for the
absence of inflation in the U.S.  economy  stems from the aftermath of the Asian
financial  crisis.  U.S. exports to Asia have slowed,  while the strength of the
dollar  caused cheap Asian imports to flood the U.S.  market and exert  downward
price pressure on domestic goods.

      Yields of U.S. Treasury  securities have remained in a fairly narrow range
during the period.  For example,  the yield of the 10-Year Treasury posted a net
decline of 29 basis points (0.29%),  beginning 1998 at 5.74% and closing on June
30, 1998 at 5.45%.  The past six months  represented  a  continuation  of strong
Treasury  performance,  which has been due to moderating  economic  growth,  low
inflation and a "flight to quality" from investors  seeking a safe haven in U.S.
Treasury  securities.  Continued  expectations  that the Asian  crisis will slow
economic  growth and force the Fed to leave the  Federal  funds  rate  unchanged
provided  additional support to the bond market. With Treasury supply waning due
to a  surplus  in  the  federal  budget  and an  increased  foreign  demand  for
Treasuries  due to their  U.S.  government  backing  and  relatively  attractive
yields,  we anticipate a positive  environment for Treasuries for the balance of
1998.

      Florida's  economy remains  strong,  particularly in the trade and service
sector,  and the State is projecting  1998's growth rate to be 2.3%. This growth
is in part fueled by the increasing population,  which grew nearly 2% in 1996 to
over 14 million  residents.  Additionally,  the tourism  industry has rebounded,
particularly in Dade County. Lastly,  Florida's fiscal year 1998 revenues, which
are heavily  dependent  on sales tax  receipts,  are ahead of  projections;  the
surplus could exceed last year's combined reserve fund of $1 billion.

                                       2

      Municipal bonds underperformed the taxable domestic bond market during the
past six months,  returning 2.69% (as measured by the LEHMAN BROTHERS  MUNICIPAL
INDEX) versus the LEHMAN  BROTHERS  AGGREGATE  INDEX'S 3.91% on a pre-tax basis.
The main forces behind municipal bond  underperformance were increased municipal
bond supply (fueled by the lowest municipal  interest rates since the 1960s) and
retail  investor  focus on the equity  markets.  We believe that  municipals are
attractively  valued versus Treasuries and our outlook for municipal  securities
is favorable.  The credit quality of most issuers remains strong,  and we expect
that the attractive  taxable  equivalent yields offered by municipal  securities
should bring investors back into the market.


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,
credits  and  coupons.  Additionally,  the  Trust  emphasizes  securities  whose
maturity  dates match the  termination  date of the Trust.  We have continued to
minimize trading  activity in the Trust during the period,  as the market prices
of a significant portion of the portfolio's bonds are currently above the prices
at which  they  were  bought.  A bond sold at a gain  would  result in the Trust
realizing  a  capital  gain,  which  may  require  a  taxable   distribution  to
shareholders.  Since one of the Trust's primary investment  objectives is to pay
out tax-exempt income, we believe that waiting to restructure the portfolio in a
higher interest rate environment remains the most prudent strategy.

      The  following  chart  compares the Trust's  current and December 31, 1997
asset composition:

      Additionally,  the Trust employs  leverage to enhance its income by paying
the Trust's preferred shareholders  short-term municipal rates and investing the
proceeds in longer maturity issues which have higher yields. The Trust's ability
to pay high monthly income may be affected by the profitability of its leverage.
The  Federal  Reserve's  neutral  interest  rate  policy has allowed the Trust's
leverage costs to remain  reasonable.  At the present,  we believe that leverage
will continue to positively  contribute to the Trust's  long-term income earning
ability.

THE BLACKROCK FLORIDA INSURED
MUNICIPAL 2008 TERM TRUST
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION & ACCOUNTING POLICIES

The  BlackRock  Florida  Insured  Municipal  2008 Term Trust (the  "Trust")  was
organized in  Massachusetts  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 income tax and Florida intangible  property tax. 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 Trustees.

   Short-term securities which mature in more than 60 days are valued at current
market  quotations.  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 or by amortizing their value on the 61st day prior to maturity,  if
their original term to maturity from date of purchase exceeded 60 days.

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

NOTE 2. AGREEMENTS

The  Trust  has  an  Investment  Advisory  Agreement  with  BlackRock  Financial
Management,  Inc.  (the  "Adviser"),  a  wholly-owned  corporate  subsidiary  of
BlackRock  Advisors,  Inc.,  which is an indirect  majority-owned  subsidiary of
PNCBank,  N.A., 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.

                                       10

NOTE 3. PORTFOLIO SECURITIES

For the six months ended June 30,  1998,  the Trust,  other than for  short-term
investments,  had no  purchases  or sales.  The federal  income tax basis of the
Trust's investments at June 30, 1998 was substantially the same as the basis for
financial reporting, and accordingly,  gross and net unrealized appreciation for
federal income tax purposes was $18,013,208.

   For federal income tax purposes, the Trust had a capital loss carryforward at
December  31,  1997  of  approximately  $212,000  which  will  expire  in  2002.
Accordingly, no capital gain distribution is expected to be paid to shareholders
until net gains have been realized in excess of such amount.

NOTE 4. CAPITAL

There  are  200  million  shares  of  $.01  par  value  of  beneficial  interest
authorized.  Of the 8,707,093  common shares  outstanding  at June 30, 1998, the
Adviser  owned 7,093  shares.  As of June 30,  1998,  there were 2,640 Series R7
preferred shares outstanding

   The Trust may classify or reclassify any unissued common shares of beneficial
interest into one or more series of preferred  stock.  On November 23, 1992, the
Trust  reclassified  1,320 shares of beneficial  interest and issued a series of
Auction Market Preferred Stock ("Preferred Stock") as follows:  Series R7--1,320
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  accumulated but unpaid  dividends.  The
stock split occurred on July 24, 1995.

   Dividends on Series R7 are  cumulative  at a rate which is reset every 7 days
based on the results of an auction.  Dividend  rates  ranged from 2.75% to 4.15%
during the six months ended June 30, 1998.

   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  trustees.  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 June 30,  1998,  the Board of  Trustees  of the Trust  declared a
dividend from  undistributed  earnings of $0.07188 per common share payable July
31, 1998 to shareholders of record on July 15, 1998.

   For the period July 1, 1998 to July 31, 1998 dividends  declared on Preferred
Stock totalled $186,397 in aggregate for the outstanding Preferred Stock series.

             THE BLACKROCK FLORIDA INSURED MUNICIPAL 2008 TERM TRUST
                           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 FLORIDA INSURED MUNICIPAL 2008 TERM TRUST
                               INVESTMENT SUMMARY
- --------------------------------------------------------------------------------


THE TRUST'S INVESTMENT OBJECTIVE

The BlackRock Florida Insured Municipal 2008 Term Trust investment  objective is
to provide current income exempt from federal income tax and Florida  intangible
personal  property 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")  is  an  SEC-registered
investment  adviser.  BlackRock and its  affiliates  currently  manage over $119
billion  on behalf of  taxable  and  tax-exempt  clients  worldwide.  Strategies
include  fixed  income,  equity and cash and may  incorporate  both domestic and
international   securities.   Domestic  fixed  income  strategies   utilize  the
government,  mortgage,  corporate and municipal bond sectors.  BlackRock manages
twenty-one  closed-end  funds that are traded on either the New York or American
stock  exchanges,  and a $23 billion  family of open-end  equity and bond funds.
Current  institutional  clients  number 334,  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  Florida
municipal  obligations  insured  as to  the  timely  payment  of  principal  and
interest.  The  Trust  may  invest  up to 20%  in  uninsured  Florida  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 Florida 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 and Florida
intangible  personal 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 fund 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:  BRF) 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.

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


<S>                              <C>
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 and 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.
