                                                               November 30, 1996



Dear Trust Shareholder:

       Interest rate  volatility in the domestic  fixed income  markets was once
again a major factor over the past twelve months. Significant swings in the pace
of U.S.  economic  growth  influenced  the bond market's  performance,  as every
release of economic  data led to market  participant  speculation  regarding the
direction of Federal Reserve monetary policy.

       Despite strong growth and rising wage  pressures,  the Fed's decision not
to raise  interest  rates at their two most recent policy  meetings has markedly
increased the stakes in the bond market. The rationale behind the Fed's decision
not to raise  interest  rates  appears  to focus on the  benign  inflation  data
released  during the third quarter.  Should  economic  growth slow and inflation
remain  benign,  the Fed will be proven correct in their inaction and the market
would be expected to rally significantly. On the other hand, signs of a stronger
economy could result in weaker bond prices as the likelihood of a Fed tightening
would increase.

       BlackRock  maintains a positive view on the bond market. On balance,  the
outlook for moderate inflation remains intact,  suggesting that further declines
in  interest  rates  are  likely.  In  addition  to this  favorable  fundamental
backdrop,  foreign  demand  for U.S.  bonds  has  increased  due to the  renewed
attractiveness of the U.S. bond market on a global basis.

       This  annual  report is  designed  to help you stay  informed  about your
investment and represents our ongoing  commitment to improving our communication
with  you.  We hope  you find  this  report  useful  now and in the  future.  We
appreciate  your confidence and look forward to helping you reach your long-term
investment goals


Sincerely,


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

Dear Shareholder:

       We are pleased to present the annual  report for The BlackRock New Jersey
Investment  Quality Municipal Trust Inc. ("the Trust") for the fiscal year ended
October 31, 1996. We would like to take this  opportunity  to review the Trust's
stock price and net asset value (NAV) performance, summarize market developments
and discuss recent portfolio management activity.

       The Trust is a  non-diversified,  actively  managed  closed-end bond fund
whose shares are traded on the American  Stock  Exchange under the symbol "RNJ".
The Trust's  investment  objective  is to provide  high  current  income that is
exempt from regular  federal and New Jersey state income taxes  consistent  with
the  preservation  of capital.  The Trust  seeks to achieve  this  objective  by
investing in investment  grade (rated "AAA" to "BBB" by a major rating agency or
of equivalent quality) municipal debt securities issued by local  municipalities
throughout New Jersey.

       The table below summarizes the performance of the Trust's stock price and
net asset value over the year:

THE FIXED INCOME MARKETS

       Significant  swings in the pace of U.S.  economic  growth  influenced the
performance  of the fixed  income  markets  over the past year.  Throughout  the
fourth  quarter  of  1995  and  through  the  first  six  weeks  of  1996,  weak
inflationary  data and sluggish  retail demand  spurred two  reductions of short
term interest rates  totaling 50 basis points (0.50%) by the Federal  Reserve to
5.25%. In response to these reductions, as well as the sharp decline in interest
rates  throughout  1995,  economic growth began to pick up in  mid-February  and
accelerated  throughout the second quarter of 1996.  Economic growth as measured
by Gross  Domestic  Product  (GDP) was  measured at an  annualized  4.7% for the
second quarter of 1996,  which led investors to believe that the Federal Reserve
would be forced  to raise  interest  rates for the first  time in over a year to
curb the pace of the economy.  However,  the pace of economic  growth has slowed
during the past few months. Softer economic data and continued moderation in the
broad  inflation  measures  during the third  quarter of 1996 allowed the Fed to
leave short term interest rates  unchanged at their August and September  policy
meetings.

       After lagging the  performance of their taxable  counterparts  during the
fourth quarter of 1995,  year-to-date  municipal bond performance as measured by
the Lehman Municipal Bond Index has outpaced that of taxable bonds  (represented
by the Lehman Aggregate  Index) returning 2.99% versus 2.84% for taxables.  This
strong  performance is the result of the relative scarcity of new municipal bond
issuance  combined  with  increased  retail  demand due to the end of "flat tax"
reform   concerns.   In   particular,   the  third  quarter  of  1996  witnessed
approximately $60 billion in cash (in the form of calls, maturities and interest
payments)  returned to  investors  and  recycled  back into the  municipal  bond
market. As the quarter progressed,  however, retail demand moderated in response
to a strengthening  stock market and declining interest rate levels.  Within the
municipal market, longer maturity municipals outperformed shorter maturities for
the year ended  October 31, as the yield of the  30-year AAA General  Obligation
(G.O.)  bond fell four basis  points  (0.04%) to 5.54%  while  yields of shorter
maturities rose.

       The New  Jersey  economy  has been  improving,  in part due to its  close
proximity to New York's financial services center,  which has experienced strong
profits  and  earnings.  The New Jersey  municipal  bond  market,  however,  has
underperformed the national market as yields fell below the psychological  5.00%
barrier for 10-year bonds and 6.00% for 30-year bonds, contributing to weak

                                       2

retail demand. New issue supply has been relatively low, with one recent notable
$712 million New Jersey  Transit  Trust deal issued  during the third quarter of
1996.

       Looking  ahead to the fourth  quarter and into 1997,  the  potential  for
weakening  supply and demand  technicals has led us to take a cautious stance on
the  municipal  market.  The  recent  decline  in  interest  rates  may spur new
issuance,  which  historically  is  heaviest  in the  fourth  quarter as issuers
complete year-end business. Additionally, although the likelihood of radical tax
reform has  diminished  since the first half of 1996, we continue to monitor the
possibility  of tax cuts over the next year and  their  potential  impact on the
municipal  bond  market.  We view any  potential  fourth  quarter  weakness as a
opportunity to add at attractive levels.

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 employs leverage at about 35% of total assets to
enhance its income by borrowing at short term municipal  rates and investing the
proceeds in longer maturity issues which have higher yields. The degree to which
the Trust can  benefit  from its use of  leverage  may affect its ability to pay
high  monthly  income.  The Federal  Reserve's  decision  not to increase  short
interest rates at their August and September  policy  meetings has benefited the
Trust,  as short term  municipal  rates (which  determine the Trust's  borrowing
costs) fell.

       The Trust has generally  favored callable premium coupon bonds throughout
the past twelve  months,  as they  characteristically  outperform par bonds in a
rising interest rate  environment.  Though interest rates have fallen  recently,
the  generally  upward  trend in rates  since  the  beginning  of 1996  proved a
favorable  environment to hold these  defensively  structured  bonds.  The Trust
maintained its focus in the  intermediate  portion of the municipal yield curve,
with nearly half of the Trust's holdings having an average life between 8 and 12
years.  Additionally,  the Trust's  credit  quality  bias  emphasizes  a barbell
strategy,  as the majority of the holdings  carry either a "AAA" or "BBB" credit
rating.  Limited  municipal  bond supply has resulted in the narrowing of yields
spreads between higher- and lower-quality municipal bonds. Should credit spreads
tighten significantly from current levels,  thereby reducing the yield advantage
of owning a lower rated bond,  we would seek to  reallocate  some of the Trustis
"BBB" issues into higher rated bonds at tighter spreads.

asset composition and credit quality allocations:

THE BLACKROCK NEW JERSEY INVESTMENT
QUALITY MUNICIPAL TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1. ACCOUNTING       The BlackRock New Jersey  Investment  Quality Municipal
POLICIES                 Trust Inc.  (the  "Trust") was organized in Maryland on
                         April  12,  1993  as  a   non-diversified,   closed-end
management  investment company. The Trust had no transactions until May 27, 1993
when it sold 7,093 shares of common  stock for  $100,012 to BlackRock  Financial
Management,  Inc., (the "Adviser").  Investment  operations commenced on June 4,
1993.

    The Trust's  investment  objective is to provide high current  income exempt
from  regular  federal  and New  Jersey  state  income tax  consistent  with the
preservation  of capital.  The ability of issuers of debt securities held by the
Trust to meet their obligations may be affected by economic  developments in the
state, a specific industry or region. No assurance can be given that the Trust's
investment objective will be achieved.

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

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

    Short-term  securities  which  mature  in 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  accretes  original  issue  discounts  or amortizes
premium on securities purchased using the interest method.

FEDERAL INCOME TAXES: For federal income tax purposes, the Trust is treated as a
separate taxpaying entity. It is the intent of the Trust to continue to meet the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies  and to  distribute  all of its 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.

DEFERRED  ORGANIZATION  EXPENSES:  A total of $16,000 was incurred in connection
with the organization of the Trust. These costs have been deferred and are being
amortized  ratably  over a period  of  sixty  months  from  the  date the  Trust
commenced investment operations.

RECLASSIFICATION  OF  CAPITAL  ACCOUNTS:  The Trust  accounts  and  reports  for
permanent differences between financial and tax reporting in accordance with the
American Institute of Certified Public Accountants'  Statement of Position 93-2:
Determination,  Disclosure  and  Financial  Statement  Presentation  of  Income,
Capital Gain and Return of Capital  Distributions by Investment  Companies.  The
effect of applying  this  statement  for the year ended  October 31, 1996 was to
increase accumulated net realized loss and increase undistributed net investment
income by $2,064.  Net investment income, net realized gains and net assets were
not affected by this change.

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 PNCAsset  Management  Group,  Inc.,  the
holding  company for PNC's asset  management  businesses  and an  Administration
Agreement with  Prudential  Mutual Fund  Management,  LLC ("PMF"),  an indirect,
wholly-owned subsidiary of The Prudential Insurance Company of America.

                                       10
<PAGE>

    The  investment  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 PMF 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.  PMF 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  investment  securities,  other
SECURITIES               than short-term investments, for the year ended October
                         31,  1996  aggregated   $17,880,665  and   $17,293,490,
                         respectively.

    The federal income tax basis of the Trust's  investments at October 31, 1996
was $19,834,126 and, accordingly, net unrealized appreciation for federal income
tax  purposes  was  $611,925  (gross  unrealized  appreciation  $613,243;  gross
unrealized depreciation $1,318).

    For federal income tax purposes,  the Trust had a capital loss  carryforward
at October 31, 1996 of  approximately  $987,000 of which  $10,000 will expire in
2001, $690,000 will expire in 2002, $280,000 will expire in 2003 and $7,000 will
expire in 2004.  Accordingly,  no capital gains  distribution  is expected to be
paid to  shareholders  until net  gains  have  been  realized  in excess of such
amount.

NOTE 4. CAPITAL          There are 200 million  shares of $.01 par value  common
                         stock authorized.  Of the 1,007,093 shares  outstanding
at October 31, 1996,  the Adviser  owned 7,093  shares.  As of October 31, 1996,
there were 300 shares of Preferred Stock Series T7 outstanding.

    The Trust may classify or  reclassify  any  unissued  shares of common stock
into  one or more  series  of  preferred  stock.  On July  29,  1993  the  Trust
reclassified  150 shares of common  stock and issued a series of Auction  Market
Preferred  Stock  ("Preferred  Stock")  Series  T7.  The  Preferred  Stock had a
liquidation  value  of  $50,000  per  share  plus  any  accumulated  but  unpaid
dividends.  On May 16, 1995 shareholders approved a proposal to split each share
of the  Trust's  Auction  Rate  Municipal  Preferred  Stock  into two shares and
simultaneously  reduce  each  share's  liquidation  preference  from  $50,000 to
$25,000 plus any  accumulated but unpaid  dividends.  The stock split occured on
July 24, 1995.

     Dividends on Series T7 are cumulative at a rate which is reset every 7 days
based on the results of an auction.  Dividend  rates  ranged from 3.23% to 4.00%
during the year ended October 31, 1996.

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

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

    The holders of  Preferred  Stock have voting  rights equal to the holders of
common stock (one vote per share) and will vote  together with holders of shares
of common stock as a single class. However,  holders of Preferred Stock are also
entitled to elect two of the Trust's  directors.  In  addition,  the  Investment
Company Act of 1940 requires that along with approval by stockholders that might
otherwise  be  required,  the  approval  of the  holders  of a  majority  of any
outstanding  preferred shares, voting separately as a class would be required to
(a) adopt any plan of  reorganization  that would adversely affect the preferred
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 October 31, 1996,  the Board of Directors
                         of the Trust  declared  a dividend  from  undistributed
earnings of $0.0578 per common share payable  November 29, 1996 to  shareholders
of record on November 15, 1996.

    For the  period  November  1, 1996  through  November  30,  1996,  dividends
declared on Preferred  Stock totalled  $20,547 in aggregate for the  outstanding
Preferred Stock.

           THE BLACKROCK NEW JERSEY INVESTMENT QUALITY MUNICIPAL TRUST
                         REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

The Shareholders  and Board of Directors of 
The BlackRock New Jersey  Investment Quality Municipal Trust:

We have audited the accompanying statement of assets and liabilities,  including
the portfolio of  investments,  of The BlackRock New Jersey  Investment  Quality
Municipal Trust as of October 31, 1996 and the related  statements of operations
for the year then ended and of changes in net investment  assets for each of the
two years in the period then ended and the financial  highlights for each of the
three  years  in the  period  then  ended  and  for  the  period  June  4,  1993
(commencement  of investment  operations) to October 31, 1993.  These  financial
statements  and  financial  highlights  are the  responsibility  of the  Trust's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements and financial highlights based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures included confirmation of securities owned at October
31, 1996 by  correspondence  with the custodian and brokers;  where replies were
not received from brokers, we performed other auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  such  financial  statements  and financial  highlights  present
fairly, in all material  respects,  the financial  position of The BlackRock New
Jersey  Investment  Quality Municipal Trust at October 31, 1996, and the results
of its  operations,  the changes in its net investment  assets and its financial
highlights  for the  respective  stated  periods in  conformity  with  generally
accepted accounting principles.

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

       We are required by the Internal Revenue Code to advise you within 60 days
of the Trust's  fiscal year end  (October 31, 1996) as to the federal tax status
of dividends  you received  during such fiscal year.  The dividend paid December

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

       Pursuant  to  the  Trust's  Dividend   Reinvestment  Plan  (the  "Plan"),
shareholders will  automatically 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  unless an election is made to receive  such
amounts in cash.  The Plan Agent will affect  purchases of shares under the Plan
in the open market.  Shareholders  who elect not to 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 American
Stock Exchange or elsewhere,  for the participants' accounts. The Trust will not
issue any new shares in connection with 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,  state or local income taxes 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 by the Plan
Agent upon at least 90 days' written  notice to all  shareholders  of the Trust.
The Plan may be  terminated by the Plan Agent or the Trust upon at least 30 days
written notice to all shareholders of the Trust. All  correspondence  concerning
the Plan should be directed to the Plan Agent at (800)  699-1BFM.  The addresses
are on the front of this report.

       THE BLACKROCK NEW JERSEY INVESTMENT QUALITY MUNICIPAL TRUST INC.
                               INVESTMENT SUMMARY
- --------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE

The  BlackRock  New  Jersey  Investment  Quality  Municipal  Trust's  investment
objective is to provide high current  income exempt from regular  Federal income
tax and New Jersey gross income tax consistent with the preservation of capital.


WHO MANAGES THE TRUST?

BlackRock  Financial  Management,  Inc.  ("BlackRock"  or the  "Adviser") is the
investment adviser for the Trust.  BlackRock is a registered  investment adviser
specializing in fixed income securities.  Currently,  BlackRock manages over $43
billion of assets  across the  government,  mortgage,  corporate  and  municipal
sectors.  These  assets are managed on behalf of  institutional  and  individual
investors in 21 closed-end funds traded on either the New York or American Stock
Exchanges,  several  open-end  funds and over 100 separate  accounts for various
clients  in the U.S.  and  overseas.  BlackRock  is a  subsidiary  of PNC  Asset
Management  Group  which is a division  of PNC Bank,  N.A.,  one of the  nations
largest banking organizations.


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  investment  grade  ("BBB" by
Standard & Poor's and "Baa" by Moody's  Investor  Services) and up to 20% of its
assets may instead be deemed to be of equivalent  credit quality by the Adviser.
The Trust  intends to invest  substantially  all of the assets in a portfolio of
investment   grade  New  Jersey  Municipal   Obligations,   which  include  debt
obligations  issued by or on behalf of New Jersey,  its political  subdivisions,
agencies and instrumentalities and by other qualifying issuers that pay interest
which, in the opinion of the bond counsel of the issuer,  is exempt from regular
Federal  income tax and New  Jersey  gross  income  tax.  New  Jersey  Municipal
Obligations are issued to obtain funds for various public  functions,  including
the   construction  of  public   facilities,   the  refinancing  of  outstanding
obligations, the obtaining of funds for general operating expenses and for loans
to other public institutions and facilities.


WHAT IS THE ADVISER'S INVESTMENT STRATEGY?

The Adviser will manage the assets of the Trust in  accordance  with the Trust's
investment  objective and policies to seek to achieve its objective by investing
in  investment  grade New Jersey  Municipal  Obligations.  The Adviser  actively
manages the assets in relation to market  conditions  and interest rate changes.
Depending  on yield and  portfolio  allocation  considerations,  the Adviser may
choose  to invest a  portion  of the  Trust's  assets  in  securities  which pay
interest that is subject to AMT (alternative  minimum tax). The Trust intends to
emphasize  investments  in  New  Jersey  Municipal  Obligations  with  long-term
maturities and expects to maintain an average portfolio maturity of 15-20 years,
but the  average  maturity  may be  shortened  or  lengthened  from time to time
depending on market conditions.

Under current market conditions the use of leverage  increases the income earned
by the Trust.  The Trust  employs  leverage  primarily  through the  issuance of
preferred  stock.   Preferred  stockholders  will  receive  dividends  based  on
short-term rates in exchange for allowing the Trust to borrow additional assets.
These assets will be invested in longer-term assets which typically offer higher
interest  rates and the  difference  between the cost of the  dividends  paid to
preferred  stockholders  and the interest earned on the  longer-term  securities
will provide higher income levels for common  stockholders in most interest rate
environments.  The Trust issued  preferred  stock to leverage  the  portfolio at
approximately  35% of total assets.  See "Leverage  Considerations in the Trust"
below.


HOW ARE THE TRUST'S SHARES PURCHASED AND SOLD? DOES THE TRUST PAY DIVIDENDS 
REGULARLY?

The Trust's  shares are traded on the American  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 fund 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 THE TRUST

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 fund in a  declining  rate  environment,  but can  cause net
assets to decline  faster in a rapidly  rising  interest rate  environment.  The
Trust may reduce,  or unwind,  the amount of leverage  employed should BlackRock
consider that  reduction to be in the best  interests of the Trust.  BlackRock's
portfolio managers  continuously monitor and regularly review the Trust's use of
leverage  and  maintain  the  ability to unwind the  leverage  if that course is
chosen.


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  OBJECTIVE.  Although  the  objective of the Trust is to provide high
current  income  exempt from  regular  Federal  income tax and New Jersey  gross
income  tax  consistent  with  the  preservation  of  capital,  there  can be no
assurance that this objective will be achieved.

DIVIDEND  CONSIDERATIONS.  The income and dividends paid by the Trust are likely
to vary over time as fixed income market conditions change. Future dividends may
be higher or lower than the dividend the Trust is currently paying.

LEVERAGE.  The Trust utilizes leverage through  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 American Stock  Exchange  (AMEX symbol:  RNJ) 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.

INVESTMENT GRADE 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.

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

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


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 the Trust.

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

                              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

                              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.

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

      BlackRock  Financial  Management  (BlackRock)  is a registered  investment
adviser which specializes in managing high quality fixed income securities, both
taxable and tax exempt.  BlackRock  currently manages over $43 billion of assets
across the government,  mortgage,  corporate and municipal sectors. These assets
are managed on behalf of many  individual  investors  in  twenty-one  closed-end
funds  traded on either the New York or American  stock  exchanges,  and several
open-end  funds  and on behalf of more  than 100  institutional  clients  in the
United States and  overseas.  BlackRock's  institutional  investor base includes
Chrysler  Corporation Master Retirement Trust,  General Retirement System of the
City of Detroit,  State  Treasurer of Florida,  Ford Motor Company Pension Plan,
General Electric Pension Trust and Unisys Corporation Master Trust.

       BlackRock  was formed in April  1988 by fixed  income  professionals  who
sought to create an asset management firm  specializing in managing fixed income
securities for individuals and  institutional  investors.  The  professionals at
BlackRock have extensive experience creating, analyzing and trading a variety of
fixed income instruments,  including the most complex structured securities.  In
fact, individuals at BlackRock are responsible for many of the major innovations
in the  mortgage-backed  and  asset-backed  securities  markets,  including  the
creation of the CMO, the floating rate CMO, the senior/subordinated pass-through
and the multi-class asset-backed security.

       BlackRock is unique  among asset  management  and  advisory  firms in the
significant  emphasis it places on the  development  of  proprietary  analytical
capabilities.  A quarter of the professionals at BlackRock work full-time in the
design,  maintenance  and use of such systems  which are otherwise not generally
available to investors.  BlackRock's  proprietary  analytical tools are used for
evaluating,  investing in and designing investment  strategies and portfolios of
fixed  income  securities,   including  mortgage   securities,   corporate  debt
securities or tax-exempt securities and a variety of hedging instruments.

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

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