NUVEEN  Tax-Exempt Unit Trusts
             PROSPECTUS
            Series 711
             January 6, 1994
    
INTEREST INCOME TO  THE TRUSTS AND  TO UNITHOLDERS, IN  THE OPINION OF  COUNSEL,
UNDER EXISTING LAW IS EXEMPT FROM FEDERAL INCOME TAX. CAPITAL GAINS, IF ANY, ARE
SUBJECT  TO TAX. IN ADDITION, INTEREST INCOME OF STATE TRUSTS IS, IN THE OPINION
OF COUNSEL,  EXEMPT,  TO THE  EXTENT  INDICATED,  FROM STATE  AND  LOCAL  TAXES.
INTEREST  INCOME OF ANY TRUST  OTHER THAN A STATE TRUST  MAY BE SUBJECT TO STATE
AND LOCAL TAXES.
 
CURRENTLY OFFERED AT PUBLIC OFFERING PRICE PLUS INTEREST ACCRUED TO THE DATE  OF
SETTLEMENT. MINIMUM PURCHASE--EITHER $5,000 OR 50 UNITS, WHICHEVER IS LESS.
 
   
THE  NUVEEN  TAX-EXEMPT  UNIT  TRUST, SERIES  711  consists  of  five underlying
separate unit  investment trusts  designated as  California Insured  Trust  219,
Florida  Insured Trust 184, Massachusetts Insured  Trust 109, New Jersey Insured
Trust 171 and Pennsylvania Insured Trust  175. Each Trust initially consists  of
delivery  statements relating  to contracts  to purchase  Bonds and, thereafter,
will consist of a diversified portfolio of obligations issued by or on behalf of
states and  territories  of the  United  States and  authorities  and  political
subdivisions  thereof (see SCHEDULES OF INVESTMENTS),  the interest on which is,
in the opinion of bond  counsel to the issuers,  exempt from Federal income  tax
under  existing law. In addition, the interest  on Bonds in each State Trust is,
in the opinion of bond  counsel to the issuers  of the obligations, exempt  from
such State's income taxes, if any. All obligations in each Traditional Trust are
rated  in the category "A" or better by Standard & Poor's Corporation or Moody's
Investors Service, Inc. on the Date of Deposit. All obligations in each  Insured
Trust  are covered  by policies  of insurance  obtained from  the Municipal Bond
Investors Assurance Corporation guaranteeing  payment of principal and  interest
when  due.  All such  policies  of insurance  remain  effective so  long  as the
obligations are outstanding. As  a result of such  insurance, the Bonds in  each
portfolio  of the  Insured Trusts  have received  a rating  of "Aaa"  by Moody's
Investors Service, Inc. and  the Bonds in  the Insured Trusts  and the Units  of
each  such  Trust  have  received  a  rating  of  "AAA"  by  Standard  &  Poor's
Corporation. INSURANCE RELATES ONLY TO THE  BONDS IN THE INSURED TRUSTS AND  NOT
TO THE UNITS OFFERED HEREBY OR TO THEIR MARKET VALUE. (See Section 5.)
    
 
THE  OBJECTIVES of the Trusts are  tax-exempt income and conservation of capital
through a diversified  investment in tax-exempt  Bonds. (SEE SECTIONS  2, 3  AND
11.)  The payment of interest and the  preservation of principal are, of course,
dependent upon the continuing ability of the issuers of Bonds and of any insurer
thereof to meet  their obligations thereunder.  There is no  guarantee that  the
Trusts' objectives will be achieved.
 
DISTRIBUTIONS  of interest  received by  each Trust  will be  made semi-annually
unless the Unitholder elects to receive them monthly or quarterly. (SEE  SECTION
13.)  Distribution of funds in the Principal Account, if any, will ordinarily be
made semi-annually.
 
FOR ESTIMATED LONG TERM RETURNS AND ESTIMATED CURRENT RETURNS to Unitholders  in
each  Trust on the  business day prior to  the Date of Deposit.  (SEE PAGE 3 AND
SECTION 9.)
 
THE PUBLIC OFFERING  PRICE per Unit  of each Trust  during the initial  offering
period  is equal to a pro rata share of the OFFERING prices of the Bonds in such
Trust's portfolio plus  a sales charge  of up  to 4.90% of  the Public  Offering
Price  (equivalent to 5.152%  of the net  amount invested); the  sales charge is
somewhat lower on Trusts  with lesser average maturities.  (SEE SECTION 6.)  The
Secondary  Market Public Offering Price per Unit for each Trust will be equal to
a pro rata share of the  sum of BID prices of the  Bonds in such Trust plus  the
sales  charges determined based on the number of years remaining to the maturity
of each  Bond. Accrued  interest from  the  preceding Record  Date to,  but  not
including,  the settlement date is added to the Public Offering Price. The sales
charge is reduced on a graduated scale for sales involving at least $100,000  or
1,000  Units and  will be applied  on whichever  basis is more  favorable to the
purchaser. (SEE SECTION 6.)
 
A UNITHOLDER MAY REDEEM UNITS at the office of the Trustee, United States  Trust
Company of New York, at prices based upon the BID prices of the Bonds. The price
received  upon  redemption  may  be  more  or  less  than  the  amount  paid  by
Unitholders, depending upon the  value of the  Bonds on the  date of tender  for
redemption.  (SEE  SECTION 19.)  The Sponsor,  although not  required to  do so,
intends to make a secondary market for  the Units of the Trusts at prices  based
upon  the BID  prices of the  Bonds in  the respective Trusts.  (SEE SECTION 7.)
RETAIN THIS PROSPECTUS FOR FUTURE REFERENCE.
 
                 THESE SECURITIES HAVE NOT BEEN  APPROVED OR DISAPPROVED BY  THE
                 SECURITIES AND EXCHANGE  COMMISSION OR ANY  STATE SECURITIES
                 COMMISSION  NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR
                 ANY STATE SECURITIES COMMISSION PASSED UPON THE  ACCURACY OR
                 ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY
                 IS A CRIMINAL OFFENSE.

    The  Estimated Long Term Return for each Trust is a measure of the return to
the investor earned  over the estimated  life of the  Trust. The Estimated  Long
Term  Return represents an  average of the  yields to maturity  (or call) of the
Bonds in  the Trust's  portfolio  calculated in  accordance with  accepted  bond
practice and adjusted to reflect expenses and sales charges. Under accepted bond
practice,  tax-exempt bonds  are customarily  offered to  investors on  a "yield
price" basis, which involves computation of  yield to maturity or to an  earlier
call date (whichever produces the lower yield), and which takes into account not
only the interest payable on the bonds but also the amortization or accretion to
a  specified date of any premium over  or discount from the par (maturity) value
in the bond's  purchase price. In  calculating Estimated Long  Term Return,  the
average  yield for  the Trust's  portfolio is  derived by  weighting each Bond's
yield by the market value of the Bond and by the amount of time remaining to the
date to which the Bond is priced. Once the average portfolio yield is  computed,
this  figure is then reduced to reflect estimated expenses and the effect of the
maximum sales  charge paid  by investors.  The Estimated  Long Term  Return  and
Estimated  Current Return  calculations do not  take into account  the delays in
payments to Unitholders  for the first  few months of  Trust operations, and  it
also  does not  take into account  the difference  in the timing  of payments to
Unitholders who choose quarterly or  semi-annual plans of distribution, each  of
which will reduce the return.
 
    Estimated  Current Return  is computed by  dividing the  Net Annual Interest
Income per Unit by the Public Offering Price. In contrast to Estimated Long Term
Return, Estimated Current Return does not reflect the amortization of premium or
accretion of discount, if any, on the Bonds in the Trust's portfolio. Net Annual
Interest Income per Unit is calculated by dividing the annual interest income to
the Trust, less estimated expenses, by the number of Units outstanding.
 
    Net Annual Interest  Income per  Unit, used to  calculate Estimated  Current
Return,  will vary  with changes  in fees  and expenses  of the  Trustee and the
Evaluator and with the redemption, maturity, exchange or sale of Bonds. A  Trust
may  experience expenses and  portfolio changes different  from those assumed in
the calculation of Estimated  Long Term Return. There  thus can be no  assurance
that  the Estimated  Current Returns or  the Estimated Long  Term Returns quoted
herein will be realized in the future. Both the Estimated Current Return and the
Estimated Long Term Return quoted  herein are based on  the market value of  the
underlying  Bonds on the business  day prior to the  Date of Deposit; subsequent
calculations of these performance measures will reflect the then current  market
value  of the underlying Bonds and may be higher or lower. For more information,
see Section 9. The Sponsor will provide estimated cash flow information relating
to a Trust without  charge to each  potential investor in  a Trust who  receives
this  prospectus and makes  an oral or  written request to  the Sponsor for such
information.

THE NUVEEN TAX-EXEMPT UNIT TRUST
   
SERIES 711
    
 
   
1.  WHAT IS THE NUVEEN TAX-EXEMPT UNIT TRUST, SERIES 711?
    
 
   
Series 711 of the Nuveen  Tax-Exempt Unit Trust is one  of a series of  separate
but  similar  investment companies  created  by the  Sponsor,  each of  which is
designated by a different Series number. This Series consists of five underlying
separate  unit  investment  trusts,  combined  under  one  trust  indenture  and
agreement,  designated California Insured Trust  219, Florida Insured Trust 184,
Massachusetts Insured Trust 109, New  Jersey Insured Trust 171 and  Pennsylvania
Insured Trust 175. The various trusts are collectively referred to herein as the
"Trusts"; the trusts in which few or none of the Bonds are insured are sometimes
referred  to as the "Traditional  Trusts", the trusts in  which all of the Bonds
are insured  as described  herein  are sometimes  referred  to as  the  "Insured
Trusts",  and  the state  trusts (both  Traditional  and Insured)  are sometimes
referred to  as the  "State Trusts."  THERE ARE  NO TRADITIONAL  TRUSTS IN  THIS
SERIES. This Series was created under the laws of the State of New York pursuant
to  a  Trust Indenture  and Agreement  dated January  6, 1994  (the "Indenture")
between John Nuveen & Co. Incorporated  (the "Sponsor") and United States  Trust
Company of New York (the "Trustee").
    
 
   
    The  Sponsor has deposited with the  Trustee delivery statements relating to
contracts for the  purchase of  municipal debt obligations  together with  funds
represented by an irrevocable letter of credit issued by a major commercial bank
in  the amount, including accrued interest,  required for their purchase (or the
obligations themselves) in  the principal amount  of $17,500,000 (the  "Bonds"),
which  initially constitute the  underlying securities of  the Trusts. Bonds may
include fixed rate obligations with regularly scheduled interest payments,  zero
coupon  bonds and stripped  obligations, which represent  evidences of ownership
interests with respect to either a principal payment or a payment of interest on
a tax-exempt obligation  ("Stripped Obligations"). See  "SUMMARY OF  PORTFOLIOS"
and  "GENERAL  TRUST INFORMATION"  for  a discussion  of  zero coupon  bonds and
Stripped Obligations. The  following principal  amounts were  deposited in  each
Trust: $3,500,000 in the California Insured Trust,
    
 
                                       6
<PAGE>
   
$3,500,000 in the Florida Insured Trust, $3,500,000 in the Massachusetts Insured
Trust,  $3,500,000  in  the  New  Jersey Insured  Trust  and  $3,500,000  in the
Pennsylvania Insured  Trust.  Some of  the  delivery statements  may  relate  to
contracts  for the purchase of "when issued"  or other Bonds with delivery dates
after the date of settlement for a purchase made on the Date of Deposit. See the
"Schedules of Investments"  and Section  4. For  a discussion  of the  Sponsor's
obligations in the event of a failure of any contract for the purchase of any of
the  Bonds and its limited right to substitute other bonds to replace any failed
contract, see Section 4.
    
 
    Payment of interest on the Bonds in each Insured Trust, and of principal  at
maturity,  is guaranteed under policies of  insurance obtained by the Sponsor or
by the issuers of the Bonds. (See  Section 5.) As a general matter, neither  the
issuer  nor the Sponsor has obtained insurance  with respect to the Bonds in any
Traditional Trust.
 
   
    The Trustee has delivered to the  Sponsor registered Units for 35,000  Units
of  the California  Insured Trust,  35,000 Units  of the  Florida Insured Trust,
35,000 Units of the Massachusetts Insured Trust, 35,000 Units of the New  Jersey
Insured Trust and 35,000 Units of the Pennsylvania Insured Trust, which together
represent ownership of the entire Series, and which are offered for sale by this
Prospectus.  Each Unit of a Trust  represents a fractional undivided interest in
the principal and net  income of such Trust  in the ratio of  10 Units for  each
$1,000 principal value of Bonds initially deposited in such Trust.
    
 
2.  WHAT ARE THE OBJECTIVES OF THE TRUSTS?
 
The  objectives of the Trusts are income  exempt from Federal income tax and, in
the case of State Trusts, where applicable, state income and intangibles  taxes,
and  conservation of capital, through an  investment in obligations issued by or
on behalf of  states and territories  of the United  States and authorities  and
political  subdivisions thereof,  the interest  on which  is, in  the opinion of
recognized bond counsel  to the  issuing governmental  authorities, exempt  from
Federal income tax under existing law. Bonds in any State Trust have been issued
primarily  by  or on  behalf of  the State  for  which such  Trust is  named and
counties, municipalities, authorities  and political  subdivisions thereof,  the
interest  on which Bonds is, in the opinion of bond counsel, exempt from Federal
and certain state income tax and  intangibles taxes, if any, for purchasers  who
qualify  as residents of that State.  Insurance guaranteeing the timely payment,
when due, of all principal and interest  on the Bonds in each Insured Trust  has
been obtained by the Sponsor or by the issuers of such Bonds from Municipal Bond
Investors  Assurance  Corporation,  and  as  a  result  of  such  insurance  the
obligations in the Insured Trusts are rated "Aaa" by Moody's Investors  Service,
Inc. and "AAA" by Standard & Poor's Corporation. (SEE SECTION 5) All obligations
in each Traditional Trust are rated in the category "A" or better (SP-1 or MIG 2
or  better  in the  case  of short  term obligations  included  in a  Short Term
Traditional Trust)  by  Standard  &  Poor's  Corporation  or  Moody's  Investors
Service,  Inc.  (including  provisional or  conditional  ratings).  In addition,
certain Bonds  in  certain  Traditional  Trusts  may  be  covered  by  insurance
guaranteeing  the timely payment, when due,  of all principal and interest. (SEE
SECTION 3.) The  portfolios of National  and State Trusts  consist of  long-term
(approximately 15 to 40 year maturities) obligations; those of Long Intermediate
Trusts  consist  of  intermediate to  long  term  (approximately 11  to  19 year
maturities) obligations; those  of Intermediate Trusts  consist of  intermediate
term  (approximately  5  to  15 year  maturities)  obligations;  those  of Short
Intermediate Trusts consist of short to intermediate term (approximately 3 to  7
year  maturities) obligations; and  those of Short Term  Trusts consist of short
term (approximately 1 to 5 year maturities) obligations.
 
                                       7
<PAGE>
There is, of course, no guarantee that the Trusts' objectives will be  achieved.
For  a  comparison of  net after-tax  return  for various  tax brackets  see the
"Taxable  Equivalent  Estimated   Current  Return  Tables"   included  in   this
Prospectus.
 
    Each  Trust consists  of fixed-rate  municipal debt  obligations. Because of
this an investment in a Trust should be made with an understanding of the  risks
which an investment in such debt obligations may entail, including the risk that
the  value of the debt obligations and  therefore of the Units will decline with
increases in  interest  rates. In  general,  the  longer the  period  until  the
maturity  of a  Bond, the more  sensitive its  value will be  to fluctuations in
interest rates. During the past decade, there have been substantial fluctuations
in interest  rates, and,  accordingly, in  the value  of debt  obligations.  The
Sponsor cannot predict whether such fluctuations will recur.
 
3.  SUMMARY OF PORTFOLIOS
 
In  selecting  Bonds for  the respective  Trusts,  the following  factors, among
others, were considered:  (i) the Standard  & Poor's Corporation  rating of  the
Bonds  or the Moody's Investors Service, Inc. rating of the Bonds (see Section 2
for a description  of minimum rating  standards), (ii) the  prices of the  Bonds
relative   to  other  bonds  of  comparable  quality  and  maturity,  (iii)  the
diversification of Bonds as to purpose of issue and location of issuer, (iv) the
maturity dates of the Bonds, and (v) in the case of the Insured Trusts only, the
availability of Municipal Bond Investors Assurance Corporation insurance on such
Bonds.
 
    In order for Bonds in the Insured  Trusts to be eligible for Municipal  Bond
Investors Assurance Corporation insurance, they must have credit characteristics
which,  in the opinion of the insurer,  would qualify them as "investment grade"
obligations. Insurance is not  a substitute for the  basic credit of an  issuer,
but  supplements the existing credit  and provides additional security therefor.
(SEE SECTION 5.)
 
    Certain bonds may carry a "mandatory put" (also referred to as a  "mandatory
tender"  or "mandatory repurchase") feature pursuant to which the holder of such
bonds will receive payment of the full principal amount thereof on a stated date
prior to the maturity date unless  such holder affirmatively acts to retain  the
bond.  Under the Indenture,  the Trustee does  not have the  authority to act to
retain Bonds with  such features; accordingly,  it will receive  payment of  the
full  principal amount of any such Bonds on the stated put date and such date is
therefore treated as the maturity date of such Bonds in selecting Bonds for  the
respective  Trusts and for  purposes of calculating the  average maturity of the
Bonds in any Trust.

CALIFORNIA INSURED TRUST 219
    
 
   
    The  Portfolio of  California Insured  Trust 219  consists of  8 obligations
issued by entities located in California.  Eight Bonds in the Trust are  payable
as  to principal and interest from the income of a specific project or authority
and are  not supported  by the  issuer's power  to levy  taxes. The  sources  of
payment for these Bonds are divided as follows: Dedicated-Tax Supported Revenue,
2;  Health Care Facility Revenue,  3; Water and/or Sewer  Revenue, 3. All of the
Bonds in the Trust, as insured, are  rated AAA by Standard & Poor's  Corporation
and Aaa by Moody's Investors Service, Inc.
    
 
   
    At  the Date of Deposit, the average maturity of the Bonds in the California
Insured Trust is 26.9  years. The average  maturity of the Bonds  in a Trust  is
calculated based upon the stated maturities of the Bonds in such Trust (or, with
respect  to Bonds for  which funds or  securities have been  placed in escrow to
redeem such Bonds on a stated call date, based upon such call date). The average
maturity of the Bonds in a Trust may  increase or decrease from time to time  as
Bonds mature or are called or sold.
    
 
   
    Approximately  5.7% of  the aggregate principal  amount of the  Bonds in the
Trust (accounting for approximately 2.3% of the aggregate offering price of  the
Bonds)  are original  issue discount  obligations. All  of these  original issue
discount bonds are "zero coupon" bonds. See "GENERAL TRUST INFORMATION--ORIGINAL
ISSUE  DISCOUNT  BONDS  AND  STRIPPED  OBLIGATIONS"  for  a  discussion  of  the
characteristics of such bonds and of the risks associated therewith.
    
 
    Approximately  29% of  the aggregate  principal amount  of the  Bonds in the
Trust consists of obligations supported by tax revenues specifically pledged  to
secure the obligations.
 
    Approximately  27% of  the aggregate  principal amount  of the  Bonds in the
Trust consists of obligations  of issuers whose  revenues are primarily  derived
from the sale of water and/or sewerage services.
 
    Approximately  44% of  the aggregate  principal amount  of the  Bonds in the
Trust consists of obligations  of issuers whose  revenues are primarily  derived
from services provided by hospitals or other health care facilities.
 
    For  a discussion of the  risks associated with investments  in the bonds of
various issuers, see "General Trust Information" in this section.
 
   
    The Sponsor entered  into contracts  to acquire  the Bonds  on December  29,
1993.  The following  summarizes certain information  about the Bonds  as of the

    Neither  cost  to  Sponsor  nor   profit  (or  loss)  to  Sponsor   reflects
underwriting  profits or losses received or  incurred by the Sponsor through its
participation  in  underwriting  syndicates.  An  underwriter  or   underwriting
syndicate  purchases bonds  from the issuer  on a negotiated  or competitive bid
basis as principal with  the motive of  marketing such bonds  to investors at  a
profit.  The Sponsor did  not participate as  either the sole  underwriter or as

a manager or member of a syndicate that acted as the original underwriter of any
of the Bonds.
 
   
    Unitholders may  elect to  have interest  distributions made  on a  monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the California Insured Trust, less estimated expenses, is estimated to accrue at
the rate of $.01411 per Unit per day under the semi-annual plan of distribution,
$.01405  per Unit per day  under the quarterly plan  of distribution and $.01397
per Unit per day under the monthly plan of distribution. It is anticipated  that
the  amount of interest to be distributed per  Unit in each year under each plan
of distribution  will initially  be  substantially equal  to the  Estimated  Net
Annual Interest Income per Unit for that plan.

TAX STATUS--CALIFORNIA INSURED TRUST
 
    For a discussion of  the Federal tax status  of income earned on  California
Insured Trust Units, see Section 11.
 
    In the opinion of Orrick, Herrington & Sutcliffe, special California counsel
to  the Series, under existing California income and property tax law applicable
to individuals who are California residents:
 
        The California  Insured  Trust  is  not  an  association  taxable  as  a
    corporation  and the income of the  California Insured Trust will be treated
    as the income of the Unitholders under the income tax laws of California.
 
        Interest on the underlying securities (which may include bonds or  other
    obligations  issued by the  governments of Puerto  Rico, the Virgin Islands,
    Guam or  the  Northern Mariana  Islands)  which  is exempt  from  tax  under
    California  personal income tax  and property tax laws  when received by the
    California Insured Trust will, under such laws,
 
                                       10
<PAGE>
    retain its status  as tax-exempt interest  when distributed to  Unitholders.
    However,  interest on the  underlying securities attributed  to a Unitholder
    which is a corporation subject to  the California franchise tax laws may  be
    includable  in its gross  income for purposes  of determining its California
    franchise tax.
 
        Under California  income  tax law,  each  Unitholder in  the  California
    Insured  Trust will have  a taxable event when  the California Insured Trust
    disposes of a security (whether by sale, exchange, redemption or payment  at
    maturity)  or when  the Unitholder  redeems or  sells Units.  Because of the
    requirement that tax cost basis be  reduced to reflect amortization of  bond
    premium, under some circumstances a Unitholder may realize taxable gain when
    Units  are sold  or redeemed  for an  amount equal  to, or  less than, their
    original cost. The total tax cost of each Unit to a Unitholder is  allocated
    among  each of  the bond  issues held  in the  California Insured  Trust (in
    accordance with the proportion of the California Insured Trust comprised  by
    each  bond issue) in order to determine his  per unit tax cost for each bond
    issue; and the tax cost  reduction requirements relating to amortization  of
    bond  premium will apply separately to the per unit cost of each bond issue.
    Unitholders' bases  in  their Units,  and  the bases  for  their  fractional
    interest in each California Insured Trust asset, may have to be adjusted for
    their  pro rata  share of accrued  interest received, if  any, on securities
    delivered after the Unitholders' respective settlement dates.
 
        Under the California  personal property tax  laws, bonds (including  the
    bonds  in  the  California  Insured  Trust  as  well  as  "regular-way"  and
    "when-issued" contracts for the purchase  of bonds) or any interest  therein
    is exempt from such tax.
 
        Any  proceeds paid under  the insurance policy issued  to the Trustee of
    the fund with respect to the bonds  in the California Insured Trust as  well
    as "regular-way" and "when-issued" contracts for the purchase of bonds which
    represent  maturing interest  on defaulted  obligations held  by the Trustee
    will be  exempt from  California personal  income tax  if, and  to the  same
    extent  as, such interest would have been so exempt if paid by the issuer of
    the defaulted obligations.
 
        Under Section 17280(b)(2) of the  California Revenue and Taxation  Code,
    interest on indebtedness incurred or continued to purchase or carry Units of
    the  California  Insured Trust  is not  deductible for  the purposes  of the
    California personal  income  tax. While  there  presently is  no  California
    authority  interpreting  this  provision,  Section  17280(b)(2)  directs the
    California Franchise  Tax Board  to  prescribe regulations  determining  the
    proper  allocation and apportionment of interest costs for this purpose. The
    Franchise Tax Board has not yet proposed or prescribed such regulations.  In
    interpreting  the generally similar Federal  provision, the Internal Revenue
    Service has taken the position that  such indebtedness need not be  directly
    traceable to the purchase or carrying of Units (although the Service has not
    contended that a deduction for interest on indebtedness incurred to purchase
    or  improve  a  personal residence  or  to  purchase goods  or  services for
    personal consumption  will be  disallowed). In  the absence  of  conflicting
    regulations  or  other California  authority,  the California  Franchise Tax
    Board generally  has  interpreted  California statutory  tax  provisions  in
    accord  with  Internal Revenue  Service  interpretations of  similar Federal
    provisions.
 
ECONOMIC FACTORS--CALIFORNIA
 
    As described  above, except  to the  extent the  Fund invests  in  temporary
investments,  the Fund will invest substantially all of its assets in California
Municipal Obligations. The Fund
 
                                       11
<PAGE>
is therefore susceptible to political, economic or regulatory factors  affecting
issuers  of California Municipal Obligations. These include the possible adverse
effects of certain California  constitutional amendments, legislative  measures,
voter  initiatives and  other matters  that are  described below.  The following
information provides only a brief summary  of the complex factors affecting  the
financial situation in California (the "State") and is derived from sources that
are  generally  available  to investors  and  are  believed to  be  accurate. No
independent verification has been made of the accuracy or completeness of any of
the following information.  It is  based in  part on  information obtained  from
various  State  and  local  agencies  in  California  or  contained  in Official
Statements for various California Municipal Obligations.
 
    There can  be  no  assurance  that future  statewide  or  regional  economic
difficulties,  and the resulting impact on  State or local governmental finances
generally, will not adversely  affect the market  value of California  Municipal
Obligations  held in  the portfolio  of the  Fund or  the ability  of particular
obligors to  make timely  payments of  debt service  on (or  relating to)  those
obligations.
 
ECONOMIC OVERVIEW
 
   
    California's  economy is  the largest  among the  50 states  and one  of the
largest in the world. The State's population of over 31 million represents 12.3%
of the  total United  States population  and grew  by 27%  in the  1980s.  Total
personal income in the State, at an estimated $640 billion in 1992, accounts for
13% of all personal income in the nation. Total employment is almost 14 million,
the majority of which is in the service, trade and manufacturing sectors.
    
 
   
    Reports  issued by  the State  Department of  Finance and  the Commission on
State Finance (the "COSF")  indicate that the State's  economy is suffering  its
worst recession since the 1930s, with prospects for recovery slower than for the
nation  as  a  whole. After  the  worst  job losses  in  any  postwar recession,
employment is expected to stabilize by late 1993 before net employment starts to
increase slowly. By early fall, 1993,  however, no upturn in employment had  yet
been  seen. The  largest job  losses have  been in  Southern California,  led by
declines in  the  aerospace  and  construction  industries.  Weakness  statewide
occurred in manufacturing, construction, services and trade. Additional military
base  closures will have further adverse effects on the State's economy later in
the decade. Unemployment is expected to  average over 9% through 1993 and  1994.
The  State's economy is only expected to  pull out of the recession slowly, once
the national recovery has begun. The Department and the COSF project a  stagnant
economy  in California until 1994. Delay  in recovery will exacerbate shortfalls
in State revenues.
    
 
CONSTITUTIONAL LIMITATIONS ON TAXES AND APPROPRIATIONS
 
    LIMITATION  ON  TAXES.  Certain  California  municipal  obligations  may  be
obligations  of issuers which rely in whole  or in part, directly or indirectly,
on AD  VALOREM property  taxes as  a source  of revenue.  The taxing  powers  of
California  local governments and districts are  limited by Article XIIIA of the
California Constitution, enacted  by the voters  in 1978 and  commonly known  as
"Proposition  13." Briefly, Article  XIIIA limits to  1% of full  cash value the
rate of AD VALOREM property taxes  on real property and generally restricts  the
reassessment  of property to 2% per year, except upon new construction or change
of ownership (subject to a number of exemptions). Taxing entities may,  however,
raise  AD VALOREM taxes above the 1% limit to pay debt service on voter-approved
bonded indebtedness.
 
    Under Article XIIIA, the basic 1% AD VALOREM tax levy is applied against the
assessed value of property as of the owner's date of acquisition (or as of March
1, 1975, if acquired
 
                                       12
<PAGE>
earlier), subject to  certain adjustments.  This system has  resulted in  widely
varying  amounts of tax on similarly  situated properties. Several lawsuits have
been filed challenging the acquisition-based assessment system of Proposition 13
and on  June 18,  1992 the  U.S. Supreme  Court announced  a decision  upholding
Proposition 13.
 
    Article  XIIIA prohibits local governments  from raising revenues through AD
VALOREM property  taxes above  the 1%  limit;  it also  requires voters  of  any
governmental  unit to give two-thirds approval  to levy any "special tax." Court
decisions, however, allowed  non-voter approved  levy of  "general taxes"  which
were not dedicated to a specific use. In response to these decisions, the voters
of the State in 1986 adopted an initiative statute which imposed significant new
limits  on the ability of local entities  to raise or levy general taxes, except
by receiving  majority  local  voter  approval.  Significant  elements  of  this
initiative,  "Proposition 62,"  have been overturned  in recent  court cases. An
initiative  proposed  to  re-enact  the  provisions  of  Proposition  62  as   a
constitutional amendment was defeated by the voters in November 1990, but such a
proposal may be renewed in the future.
 
    APPROPRIATIONS  LIMITS. California and its  local governments are subject to
an annual  "appropriations limit"  imposed by  Article XIIIB  of the  California
Constitution,  enacted  by  the  voters in  1979  and  significantly  amended by
Propositions 98 and 111 in 1988 and 1990, respectively. Article XIIIB  prohibits
the  State or any covered local government from spending "appropriations subject
to limitation" in  excess of the  appropriations limit imposed.  "Appropriations
subject  to limitation" are  authorizations to spend  "proceeds of taxes," which
consists of  tax  revenues and  certain  other funds,  including  proceeds  from
regulatory  licenses,  user  charges or  other  fees,  to the  extent  that such
proceeds exceed the cost of providing  the product or service, but "proceeds  of
taxes" excludes most State subventions to local governments. No limit is imposed
on appropriations of funds which are not "proceeds of taxes," such as reasonable
user charges or fees, and certain other non-tax funds, including bond proceeds.
 
    Among  the  expenditures not  included in  the Article  XIIIB appropriations
limit are (1)  the debt  service cost  of bonds  issued or  authorized prior  to
January  1, 1979, or  subsequently authorized by  the voters, (2) appropriations
arising from certain  emergencies declared by  the Governor, (3)  appropriations
for  certain  capital  outlay  projects,  (4)  appropriations  by  the  State of
post-1989  increases  in  gasoline  taxes  and  vehicle  weight  fees,  and  (5)
appropriations made in certain cases of emergency.
 
    The  appropriations  limit for  each year  is  adjusted annually  to reflect
changes in  cost  of  living  and  population,  and  any  transfers  of  service
responsibilities  between government units. The definitions for such adjustments
were liberalized in 1990 to follow more closely growth in California's economy.
 
    "Excess" revenues are measured over a two-year cycle. Local governments must
return any excess to taxpayers by rate  reduction. The State must refund 50%  of
any excess, with the other 50% paid to schools and community colleges. With more
liberal  annual adjustment factors since 1988, and depressed revenues since 1990
because of the  recession, few  governments are currently  operating near  their
spending  limits, but this condition may change over time. Local governments may
by voter approval exceed their spending limits for up to four years.
 
    Because of the complex nature of Articles XIIIA and XIIIB of the  California
Constitution,  the ambiguities and possible  inconsistencies in their terms, and
the impossibility of predicting future  appropriations or changes in  population
and  cost of living, and  the probability of continuing  legal challenges, it is
not currently possible to determine fully the impact of
 
                                       13
<PAGE>
Article XIIIA or  Article XIIIB on  California Municipal Obligations  or on  the
ability  of  California  or  local  governments  to  pay  debt  service  on such
California Municipal Obligations. It  is not presently  possible to predict  the
outcome  of any pending litigation with respect to the ultimate scope, impact or
constitutionality of either Article XIIIA or Article XIIIB, or the impact of any
such determinations  upon State  agencies or  local governments,  or upon  their
ability  to  pay  debt  service  on  their  obligations.  Future  initiatives or
legislative changes in laws or the  California Constitution may also affect  the
ability of the State or local issuers to repay their obligations.
 
   
    OBLIGATIONS  OF THE STATE  OF CALIFORNIA. As of  October 1, 1993, California
had approximately $18.1  billion of  general obligation  bonds outstanding,  and
$6.4  billion remained authorized  but unissued. In addition,  at June 30, 1993,
the State had lease-purchase obligations, payable from the State's General Fund,
of approximately $4.0 billion. In fiscal  year 1992-93, debt service on  general
obligation  bonds and lease-purchase debt was approximately 4.1% of General Fund
revenues. The  State has  paid the  principal  of and  interest on  its  general
obligation bonds, lease-purchase debt and short-term obligations when due.
    
 
    RECENT  FINANCIAL RESULTS. The principal sources of General Fund revenues in
1991-92 were the  California personal income  tax (42% of  total revenues),  the
sales  tax (39%), bank and corporation taxes (11%), and the gross premium tax on
insurance (3%). California maintains a  Special Fund for Economic  Uncertainties
(the  "Economic Uncertainties Fund"),  derived from General  Fund revenues, as a
reserve to meet cash needs of the General Fund.
 
    GENERAL. Throughout  the 1980's,  State spending  increased rapidly  as  the
State population and economy also grew rapidly, including increased spending for
many  assistance  programs  to  local  governments,  which  were  constrained by
Proposition 13 and other laws. The largest State program is assistance to  local
public  school districts.  In 1988, an  initiative (Proposition  98) was enacted
which (subject to  suspension by a  two-thirds vote of  the Legislature and  the
Governor)  guarantees local school  districts and community  college districts a
minimum share of State General Fund revenues (currently about 33%).
 
    Since the  start  of  1990-91  Fiscal Year,  the  State  has  faced  adverse
economic,  fiscal,  and  budget  conditions.  The  economic  recession seriously
affected State tax revenues.  It also caused  increased expenditures for  health
and  welfare programs. The  State is also  facing a structural  imbalance in its
budget with  the largest  programs  supported by  the General  Fund  (education,
health,  welfare and corrections) growing at  rates higher than the growth rates
for the principal revenue sources  of the General Fund.  As a result, the  State
entered  a period of budget imbalance,  with expenditures exceeding revenues for
four of the five fiscal years ending in 1991-92; revenues and expenditures  were
about  equal  in 1992-93.  By June  30, 1993,  the State's  General Fund  had an
accumulated deficit, on a budget basis, of approximately $2.2 billion.
 
    As a consequence of the large budget imbalances built up over the past three
years, the State  depleted its available  cash resources. The  State has had  to
rely  increasingly on  a series  of external  borrowings to  meet its  cash flow
requirements.
 
    1992-93 FISCAL YEAR.  At  the outset of the  1992-93 Fiscal Year, the  State
estimated that approximately $7.9 billion of budget actions would be required to
end  the fiscal year  without a budget  deficit. The difficulty  of taking these
actions delayed enactment of a budget for more than two months past the start of
the 1992-93 Fiscal Year. With the failure to enact a budget by July 1, 1992, the
State  had  no  legal   authority  to  pay  many   of  its  vendors  until   the
 
                                       14
<PAGE>
budget  was  passed; nevertheless,  certain obligations  (such as  debt service,
school apportionments,  welfare payments,  and employee  salaries) were  payable
because  of continuing or special appropriations,  or court orders. However, the
State Controller did not have enough cash to  pay as they came due all of  these
ongoing  obligations, as well as valid  obligations incurred in the prior fiscal
year.
 
    Because of the delay in enacting the  budget, the State could not carry  out
its normal cash flow borrowing and, starting on July 1, 1992, the Controller was
required  to issue  "registered warrants" in  lieu of normal  warrants backed by
cash  to  pay  many   State  obligations.  Available  cash   was  used  to   pay
constitutionally mandated and priority obligations. Between July 1 and September
3,  1992, the  Controller issued an  aggregate of approximately  $3.8 billion of
registered warrants, all  of which were  called for redemption  by September  4,
1992  following enactment of the 1992-93 Budget Act and issuance by the State of
$3.3 billion of Interim Notes.
 
    The 1992-93 Budget Bill was signed on September 2, 1992. The 1992-93  Budget
Act  provides for  expenditures of  $57.4 billion  and consists  of General Fund
expenditures of $40.8  billion and Special  Fund and Bond  Fund expenditures  of
$16.6  billion. The Department of Finance estimated  there would be a balance in
the Special Fund for Economic Uncertainties of $28 million on June 30, 1993.
 
    The $7.9 billion budget  gap was closed through  a combination of  increased
revenues  and transfers and  expenditure cuts. The  principle reductions were in
health and welfare,  K-12 schools  and community  colleges, State  aid to  local
governments,  higher education (partially offset by increased student fees), and
various other programs. In addition, funds were transferred from special  funds,
collections of State revenues were accelerated, and other adjustments were made.
 
   
    As  in the  prior year,  the economic  and fiscal  assumptions on  which the
1992-93 Budget Act was based  proved to be too  optimistic. As the recession  in
the  State continued for a third  year, State revenues again lagged projections.
The Department of Finance  projected revenues in 1992-93  of $2.4 billion  below
projections  and expenditures $300  million higher. As  a result, the Department
predicted the General Fund ended at June 30, 1993 with a fund balance deficit of
about $2.2 billion, almost unchanged from June 30, 1992. The projected  negative
balance of the Special Fund for Economic Uncertainties is $2.75 billion.
    
 
    1993-94  BUDGET. The 1993-94 Budget represents the third consecutive year of
extremely difficult budget  choices for  the State,  in view  of the  continuing
recession.  The Budget Act, signed  on June 30, 1993,  provides for General Fund
expenditures of $38.5 billion, a 6.3% decline from the prior year. Revenues  are
projected  at $40.6 billion, about  $400 million below the  prior year. To bring
the budget into  balance, the Budget  Act and related  legislation provided  for
transfer  of  $2.6 billion  of local  property taxes  to school  districts, thus
relieving  State  support   obligations;  reductions  in   health  and   welfare
expenditures;  reductions  in  support  for  higher  education  institutions;  a
two-year suspension  of  the renters'  tax  credit; and  miscellaneous  cuts  in
general  government spending  and certain  one-time and  accounting adjustments.
There were no general state tax increases, but a 0.5% temporary state sales  tax
scheduled  to expire on  June 30 was  extended for six  months, and dedicated to
support local government public safety costs.
 
    As part of the 1993-94 Budget, the Governor implemented a plan to repay  the
accumulated $2.75 billion deficit in the Special Fund for Economic Uncertainties
over  18 months, funding the deficit  with external borrowing maturing not later
than December 31, 1994.  About $1.6 billion  of the deficit  is scheduled to  be
repaid by June 30, 1994, with the balance
 
                                       15

paid by December 31, 1994. Taking this borrowing into account, the Department of
Finance  projects  the  Special Fund  for  Economic Uncertainties  would  have a
balance of about $600 million at June  30, 1994, and about $100 million at  June
30, 1995.
 
   
____Although  State revenues  have been close  to projections  through the first
four months of the 1993-94 fiscal  year, the continued recessionary economy  may
result in weaker than projected revenues later in the year.
    
   
    The  State's severe financial difficulties for  the current budget year will
result in continued  pressure upon  almost all  local governments,  particularly
school  districts and  counties which  depend on  State aid.  Despite efforts in
recent years to increase taxes  and reduce governmental expenditures, there  can
be no assurance that the State will not face budget gaps in the future.
    
 
    BOND  RATING.   State  general obligation bonds are  currently rated "Aa" by
Moody's and "A+" by S&P.  Both of these ratings  were reduced from "AAA"  levels
which  the  State held  until late  1991. There  can be  no assurance  that such
ratings will  be  maintained  in  the  future.  It  should  be  noted  that  the
creditworthiness  of  obligations  issued  by local  California  issuers  may be
unrelated to  the  creditworthiness  of  obligations  issued  by  the  State  of
California,  and that there  is no obligation on  the part of  the State to make
payment on such local obligations in the event of default.
 
   
    LEGAL PROCEEDINGS.   The  State  is involved  in certain  legal  proceedings
(described  in the State's recent financial statements) that, if decided against
the State, may require the State to make significant future expenditures or  may
substantially  impair revenues. The U.S. Supreme Court has granted review of two
cases  challenging  California's  "unitary"   method  of  taxing   multinational
corporations.  Although this taxing method has  since been changed, if the State
loses these cases, it could be liable for tax refunds and lost receipts of taxes
assessed totalling $3.5 billion to $4 billion.
    
OBLIGATIONS OF OTHER ISSUERS
 
    OTHER ISSUERS OF  CALIFORNIA MUNICIPAL  OBLIGATIONS. There are  a number  of
state  agencies, instrumentalities and political  subdivisions of the State that
issue Municipal Obligations, some  of which may  be conduit revenue  obligations
payable  from payments  from private  borrowers. These  entities are  subject to
various economic  risks  and  uncertainties,  and  the  credit  quality  of  the
securities  issued by them may vary considerably  from the credit quality of the
obligations backed by the full faith and credit of the State.
 
   
    STATE ASSISTANCE.  Property  tax  revenues  received  by  local  governments
declined  more than 50%  following passage of  Proposition 13. Subsequently, the
California Legislature enacted measures to provide for the redistribution of the
State's General  Fund surplus  to local  agencies, the  reallocation of  certain
State  revenues to  local agencies  and the  assumption of  certain governmental
functions by the State  to assist municipal issuers  to raise revenues.  Through
1990-91, local assistance (including public schools) accounted for around 75% of
General  Fund  spending.  To  reduce  State  General  Fund  support  for  school
districts, the  1992-93  and 1993-94  Budget  Act caused  local  governments  to
transfer $3.9 billion of property tax revenues to school districts, representing
loss of all of the post-Proposition 13 "bailout" aid. The largest share of these
transfers came from counties, and the balance from cities, special districts and
redevelopment  agencies. In  order to  make up  this shortfall,  the Legislature
proposed and voters approved  dedicating 0.5% of the  sales tax to counties  and
cities for public safety purposes. In addition, the Legislature has changed laws
to relieve local governments of certain mandates, allowing them to reduce costs.
    
 
                                       16
<PAGE>
    To  the  extent  the  State  should  be  constrained  by  its  Article XIIIB
appropriations limit, or its obligation to  conform to Proposition 98, or  other
fiscal  considerations,  the absolute  level, or  the rate  of growth,  of State
assistance to local governments may be reduced. Any such reductions in State aid
could compound the serious fiscal constraints already experienced by many  local
governments,  particularly counties. At least  one rural county (Butte) publicly
announced that it might  enter bankruptcy proceedings  in August 1990,  although
such  plans  were put  off after  the Governor  approved legislation  to provide
additional funds for the county. Other  counties have also indicated that  their
budgetary  condition is  extremely grave.  The Richmond  Unified School District
(Contra Costa  County)  entered  bankruptcy  proceedings in  May  1991  but  the
proceedings have been dismissed.
 
    ASSESSMENT  BONDS.  California  Municipal Obligations  which  are assessment
bonds may be adversely affected by a general decline in real estate values or  a
slowdown in real estate sales activity. In many cases, such bonds are secured by
land  which  is  undeveloped at  the  time  of issuance  but  anticipated  to be
developed within a few years after issuance.  In the event of such reduction  or
slowdown,  such development may not occur  or may be delayed, thereby increasing
the risk of a  default on the  bonds. Because the  special assessments or  taxes
securing  these  bonds are  not  the personal  liability  of the  owners  of the
property assessed, the lien on the property is the only security for the  bonds.
Moreover,  in  most cases  the issuer  of these  bonds is  not required  to make
payments on the bonds in the event of delinquency in the payment of  assessments
or  taxes, except from  amounts, if any,  in a reserve  fund established for the
bonds.
 
    CALIFORNIA LONG-TERM LEASE OBLIGATIONS.  Certain California long-term  lease
obligations, though typically payable from the general fund of the municipality,
are subject to "abatement" in the event the facility being leased is unavailable
for  beneficial use  and occupancy  by the municipality  during the  term of the
lease. Abatement is not a default, and there may be no remedies available to the
holders of  the  certificates  evidencing  the lease  obligation  in  the  event
abatement  occurs. The  most common cases  of abatement are  failure to complete
construction of the  facility before the  end of the  period during which  lease
payments  have been  capitalized and uninsured  casualty losses  to the facility
(E.G., due to earthquake). In the event abatement occurs with respect to a lease
obligation, lease  payments  may  be interrupted  (if  all  available  insurance
proceeds  and reserves are exhausted) and the  certificates may not be paid when
due.
 
   
    Several years  ago the  Richmond Unified  School District  (the  "District")
entered  into a  lease transaction in  which certain existing  properties of the
District were sold and leased back in  order to obtain funds to cover  operating
deficits.  Following a fiscal crisis in which the District's finances were taken
over by  a State  receiver  (including a  brief  period under  bankruptcy  court
protection),  the  District  failed  to  make  rental  payments  on  this lease,
resulting in  a lawsuit  by the  Trustee for  the Certificate  of  Participation
holders,  in  which the  State was  a named  defendant (on  the grounds  that it
controlled the District's  finances). One of  the defenses raised  in answer  to
this  lawsuit was  the invalidity of  the original lease  transaction. The trial
court has upheld the validity of the District's lease. The case is likely to  be
settled,  but if  it is  not, further appeals  may occur.  Any ultimate judgment
against the Trustee may  have adverse implications for  lease transactions of  a
similar nature by other California entities.
    
 
    OTHER  CONSIDERATIONS.  The repayment  of industrial  development securities
secured by real property may be affected by California laws limiting foreclosure
rights of creditors. Securities backed by health care and hospital revenues  may
be  affected by  changes in State  regulations governing  cost reimbursements to
health care providers under Medi-Cal (the
 
                                       17
<PAGE>
State's Medicaid program),  including risks  related to the  policy of  awarding
exclusive contracts to certain hospitals.
 
    Limitations  on  AD  VALOREM  property taxes  may  particularly  affect "tax
allocation" bonds issued  by California redevelopment  agencies. Such bonds  are
secured  solely by the increase in assessed valuation of a redevelopment project
area after  the start  of redevelopment  activity. In  the event  that  assessed
values  in the redevelopment  project decline (E.G., because  of a major natural
disaster such as an earthquake), the  tax increment revenue may be  insufficient
to  make principal and  interest payments on  these bonds. Both  Moody's and S&P
suspended ratings  on California  tax allocation  bonds after  the enactment  of
Articles XIIIA and XIIIB, and only resumed such ratings on a selective basis.
 
    Proposition  87, approved  by California voters  in 1988,  requires that all
revenues produced by a tax rate increase go directly to the taxing entity  which
increased  such tax rate to repay that entity's general obligation indebtedness.
As a result, redevelopment  agencies (which, typically, are  the issuers of  tax
allocation securities) no longer receive an increase in tax increment when taxes
on  property in  the project area  are increased to  repay voter-approved bonded
indebtedness.
 
    The effect of these  various constitutional and  statutory changes upon  the
ability of California municipal securities issuers to pay interest and principal
on  their obligations remains unclear. Furthermore, other measures affecting the
taxing or spending authority of California or its political subdivisions may  be
approved  or enacted in  the future. Legislation  has been or  may be introduced
which would modify  existing taxes  or other revenue-raising  measures or  which
either  would further limit  or, alternatively, would  increase the abilities of
state and local governments to impose  new taxes or increase existing taxes.  It
is  not presently possible to  predict the extent to  which any such legislation
will be enacted. Nor  is it presently  possible to determine  the impact of  any
such  legislation  on California  Municipal Obligations  in  which the  Fund may
invest, future  allocations  of  state  revenues to  local  governments  or  the
abilities  of state or  local governments to  pay the interest  on, or repay the
principal of, such California Municipal Obligations.
 
    Substantially all of California is within an active geologic region  subject
to major seismic activity. Any California Municipal Obligation in the California
Insured  Trust  could be  affected  by an  interruption  of revenues  because of
damaged facilities, or, consequently, income tax deductions for casualty  losses
or  property tax assessment reductions.  Compensatory financial assistance could
be constrained by  the inability of  (i) an issuer  to have obtained  earthquake
insurance  coverage  at reasonable  rates;  (ii) an  insurer  to perform  on its
contracts of insurance in the event  of widespread losses; or (iii) the  Federal
or  State  government to  appropriate sufficient  funds within  their respective
budget limitations.

CALIFORNIA TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The following tables show the approximate taxable estimated current  returns
for  individuals  that are  equivalent to  tax-exempt estimated  current returns
under combined Federal and  state taxes, using  published 1994 marginal  Federal
tax  rates and marginal state tax rates  currently available and scheduled to be
in  effect.  The  tables  incorporate  increased  tax  rates  for  higher-income
taxpayers  that were  included in  the Revenue  Reconciliation Act  of 1993. For
cases in which more than one state  bracket falls within a Federal bracket,  the
highest  state bracket is combined with  the Federal bracket. The combined state
and Federal tax  brackets shown  reflect the fact  that state  tax payments  are
currently  deductible for Federal  tax purposes. The  tables illustrate what you
would have to  earn on  taxable investments  to equal  the tax-exempt  estimated
current  return for your income  tax bracket. A taxpayer's  marginal tax rate is
affected by both his taxable income  and his adjusted gross income. Locate  your
adjusted  gross and  your taxable  income (which  is your  adjusted gross income
reduced by any deductions and exemptions), then locate your tax bracket based on
joint or single  tax filing.  Read across  to the  equivalent taxable  estimated
current return you would need to match the tax-free income.

- ------------------
      1 The table reflects the effect of the limitations  on itemized deductions and the deduction for personal exemptions.  They
were  designed to phase out certain benefits of these deductions for higher income taxpayers. These limitations, in effect, raise
the current maximum marginal Federal tax rate to approximately 44.0  percent for taxpayers filing a joint return and entitled  to
four  personal exemptions and to  approximately 41.0 percent for taxpayers  filing a single return  entitled to only one personal
exemption. These limitations are  subject to certain maximums,  which depend on  the number of exemptions  claimed and the  total
amount  of the taxpayer's itemized  deductions. For example, the limitation  on itemized deductions will  not cause a taxpayer to
lose more than 80% of his allowable itemized deductions,  with certain exceptions. The table also reflects California income  tax
laws  that increase state income tax rates for high income taxpayers,  limit itemized deductions and phase out the benefit of the
personal exemption credit and the dependent exemption credit in a manner similar to Federal tax law.
      2 Federal tax rate reverts to 36.0% and the state tax rate reverts to the applicable stated maximum rate after the 80%  cap
on the limitation on itemized deductions, under federal or state law, as appropriate has been met.
      3 Federal tax rate reverts to 39.6% after the 80% cap on the limitation on itemized deductions has been met.

    A  comparison of tax-free  and equivalent taxable  estimated current returns
with the returns on  various taxable investments is  one element to consider  in
making  an  investment  decision. The  Sponsor  may  from time  to  time  in its
advertising and sales materials  compare the then  current estimated returns  on
the Trust and returns over specified periods on other similar Nuveen Trusts with
returns  on taxable investments such as corporate or U.S. Government bonds, bank
CD's and  money  market  accounts or  money  market  funds, each  of  which  has
investment  characteristics  that  may  differ from  those  of  the  Trust. U.S.
Government bonds, for example, are  backed by the full  faith and credit of  the
U.S. Government and bank CD's and money market accounts are insured by an agency
of  the federal government. Money market accounts and money market funds provide
stability of principal, but pay interest  at rates that vary with the  condition
of  the short-term debt market. The  investment characteristics of the Trust are
described more fully elsewhere in this Prospectus.

FLORIDA INSURED TRUST 184
    
   
    The  Portfolio of Florida Insured Trust 184 consists of 8 obligations issued
by entities located in Florida and one obligation issued by an entity located in
the Territory of Puerto Rico. Two Bonds in the Trust are general obligations  of
the  governmental  entities issuing  them and  are backed  by the  taxing powers
thereof. Seven Bonds in the Trust are payable as to principal and interest  from
the  income of  a specific  project or  authority and  are not  supported by the
issuer's power to levy taxes. The sources of payment for these Bonds are divided
as follows:  Electrical System  Revenue,  1; Health  Care Facility  Revenue,  2;
Combination  Utility Revenue, 2; Water and/or Sewer Revenue, 2. All of the Bonds
in the Trust, as insured, are rated AAA by Standard & Poor's Corporation and Aaa
by Moody's Investors Service, Inc.
    
 
   
    At the Date of  Deposit, the average  maturity of the  Bonds in the  Florida
Insured  Trust is 28.9  years. The average maturity  of the Bonds  in a Trust is
calculated based upon the stated maturities of the Bonds in such Trust (or, with
respect to Bonds for  which funds or  securities have been  placed in escrow  to
redeem such Bonds on a stated call date, based upon such call date). The average
maturity  of the Bonds in a Trust may  increase or decrease from time to time as
Bonds mature or are called or sold.
    
 
   
    Approximately 43.7% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 41.5% of the aggregate offering price of the
Bonds)  are original issue discount obligations. Certain of these original issue
discount obligations, amounting to  4.0% of the  aggregate principal amount  and
1.1%  of  the aggregate  offering price  of the  Bonds in  the Trust,  are "zero
coupon" bonds. See "GENERAL TRUST INFORMATION--ORIGINAL ISSUE DISCOUNT BONDS AND
STRIPPED  OBLIGATIONS"  for  a  discussion   of  the  characteristics  of   such
obligations and of the risks associated therewith.
    
 
    Approximately  22% of  the aggregate  principal amount  of the  Bonds in the
Trust consists of obligations  of issuers whose  revenues are primarily  derived
from  the sale of  services of two  or more different  municipal utility systems
operating as a single entity.
 
    Approximately 29% of  the aggregate  principal amount  of the  Bonds in  the
Trust  consists of obligations  of issuers whose  revenues are primarily derived
from services provided by hospitals or other health care facilities.
 
    For a discussion of  the risks associated with  investments in the bonds  of
various issuers, see "General Trust Information" in this section.
 
   
    The Sponsor entered into contracts to acquire the Bonds between December 21,
1993 and January 4, 1994. The following summarizes certain information about the
Bonds as of the business day prior to the Date of Deposit:

</TABLE>
 
   
    Neither   cost  to  Sponsor  nor  profit   (or  loss)  to  Sponsor  reflects
underwriting profits or losses received or  incurred by the Sponsor through  its
participation   in  underwriting  syndicates.  An  underwriter  or  underwriting
syndicate purchases bonds  from the issuer  on a negotiated  or competitive  bid
basis  as principal with  the motive of  marketing such bonds  to investors at a
profit. The Sponsor participated as either the sole underwriter or manager or as
a member of the syndicates which were the original underwriters of 15.0% of  the
aggregate principal amount of the Bonds.
    
 
    Unitholders  may elect  to have  interest distributions  made on  a monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the Florida Insured
 
                                       22

Trust, less estimated expenses,  is estimated to accrue  at the rate of  $.01406
per  Unit per day under  the semi-annual plan of  distribution, $.01401 per Unit
per day under the quarterly  plan of distribution and  $.01392 per Unit per  day
under  the monthly plan  of distribution. It  is anticipated that  the amount of
interest to be distributed per Unit in each year under each plan of distribution
will initially  be substantially  equal  to the  Estimated Net  Annual  Interest
Income per Unit for that plan.

TAX STATUS--FLORIDA INSURED TRUST
 
    For a  discussion of  the Federal  tax status  of income  earned on  Florida
Insured Trust Units, see Section 11.
 
    The assets of the Florida Insured Trust (the "Trust") will consist solely of
interest-bearing obligations issued by or on behalf of the State of Florida, its
political  subdivisions and authorities  or by the  Commonwealth of Puerto Rico,
Guam, the Virgin Islands, American Samoa,  or the Northern Mariana Islands  (the
"Florida Bonds").
 
    In  the opinion  of Carlton, Fields,  Ward, Emmanuel, Smith  & Cutler, P.A.,
special counsel for the Trust for Florida tax matters, under existing law:
 
        For Florida state income tax purposes, the Trust will not be subject  to
    the  Florida income tax imposed by the Florida Code so long as the Trust has
    no income subject to federal  taxation. In addition, political  subdivisions
    of Florida do not impose any income taxes.
 
        Because   Florida  does  not  impose   an  income  tax  on  individuals,
    non-corporate Unitholders will not be subject  to any Florida income tax  on
    income  realized by the Trust. Each  corporate Unitholder will be subject to
    Florida income taxation  on its share  of the income  realized by the  Trust
    notwithstanding  the tax  exempt status  of the  interest received  from any
    bonds under Section 103(a) of the Internal Revenue Code of 1986 or any other
    federal law,  unless the  interest  income constitutes  nonbusiness  income.
    Nevertheless,  any corporate Unitholder that  has its commercial domicile in
    Florida will be taxable  under the Florida  Code on its  share of the  Trust
    income which constitutes nonbusiness income.
 
                                       23
<PAGE>
        Trust  Units will  be subject  to Florida  estate tax  only if  owned by
    Florida residents,  certain natural  persons not  domiciled in  Florida,  or
    certain  natural persons  not residents of  the United  States. However, the
    Florida estate tax is  limited to the amount  of the credit allowable  under
    the  applicable Federal  Revenue Act  (currently Section  2011 (and  in some
    cases Section 2102) of  the Internal Revenue Code  of 1986, as amended)  for
    death taxes actually paid to the several states.
 
        Neither  the Florida Bonds nor the Units  will be subject to the Florida
    ad valorem property tax or Florida sales or use tax.
 
        Because  Bonds  issued  by  the  State  of  Florida  or  its   political
    subdivisions  or  by  the  Commonwealth of  Puerto  Rico,  Guam,  the Virgin
    Islands, American Samoa  and the  Northern Mariana Islands  are exempt  from
    Florida  intangible personal  property taxation  under Chapter  199, Florida
    Statutes, as amended, the  Trust will not be  subject to Florida  intangible
    personal  property tax. In addition, the  Unitholders will not be subject to
    Florida intangible personal property tax on the Units.
 
ECONOMIC FACTORS--FLORIDA
 
    POPULATION.  In 1980, Florida was the  seventh largest state in the U.S.  by
population. The State has grown dramatically since then and as of April 1, 1992,
ranks fourth with an estimated population of 13.2 million. Florida's attraction,
as both a growth and retirement state, has kept net migration fairly steady with
an  average of  277,000 new residents  a year  from 1980 through  1990. The U.S.
average population increase  since 1980  is about 1%  annually, while  Florida's
average annual rate of increase is about 3%. Florida continues to be the fastest
growing  of  the eleven  largest states.  This strong  population growth  is one
reason the State's economy is performing better  than the nation as a whole.  In
addition to attracting senior citizens to Florida as a place for retirement, the
State  is  also recognized  as attracting  a significant  number of  working age
individuals. Since 1980, the prime working  age population (18-44) has grown  at
an  average  annual rate  of  3.6%. The  share  of Florida's  total  working age
population (18-59) to total State population is approximately 53%. This share is
not expected to change appreciably into the twenty-first century.
 
    INCOME.  The  State's personal  income has  been growing  strongly the  last
several  years and has generally  outperformed both the U.S.  as a whole and the
southeast in particular, according  to the U.S. Department  of Commerce and  the
Florida  Consensus Economic Estimating Conference. This  is due to the fact that
Florida's population has been growing at a very strong pace and, since the early
1970's, the State's economy has diversified so as to provide greater  insulation
from  national  economic  downturns.  As a  result,  Florida's  real  per capita
personal income overtook the national average in 1985 and has tracked above  the
southeast as a whole for most of the 1980's. From 1980 through 1990, the State's
real  per capita personal  income rose at an  average of 7%  per year, while the
national real per  capita personal income  increased at an  average of 6.8%  per
year.
 
    Because  Florida has  a proportionately  greater retirement  age population,
property income (dividends,  interest, and rent)  and transfer payments  (Social
Security  and pension  benefits, among other  sources of  income) are relatively
more important  sources  of  income.  For example,  Florida's  total  wages  and
salaries  and other  labor income  in 1989 was  55.3% of  total personal income,
while a similar figure for the nation for 1990 was 65.0%. Transfer payments  are
typically  less  sensitive to  the business  cycle  than employment  income and,
therefore, act as stabilizing forces in weak economic periods.
 
    The State's per capita personal income in 1991 of $18,880 was slightly below
the national  average  of  $19,082  and significantly  ahead  of  that  for  the
southeast United States, which was $16,927. Real personal income in the State is
estimated to have increased 0.7% in
 
                                       24
<PAGE>
1991-92  and to increase 5.1%  in 1993-94. By the  end of 1993-94, real personal
income per capita  in the  State is  expected to  average 3.6%  higher than  its
1991-92 level.
 
    EMPLOYMENT.   Since 1980, the  State's job creation rate  is well over twice
the rate for the nation as a whole, and its growth rate in new  non-agricultural
jobs is the fastest of the 11 most populous states, second only to California in
the  absolute number of new jobs created. Contributing to the State's rapid rate
of growth  in employment  and income  is international  trade. Since  1980,  the
State's  unemployment rate has generally been below that of the U.S. Only in the
last two years  has the State's  unemployment rate moved  ahead of the  national
average. The average rate in Florida since 1980 has been 7.0% while the national
average  is  7.2%. According  to the  U.S. Department  of Commerce,  the Florida
Department of Labor and Employment Security, and the Florida Consensus  Economic
Estimating  Conference (together, the  "Organization"), the State's unemployment
rate was 7.3% during 1991. As  of January 1993, the Organization estimates  that
the  unemployment rate will be  7.4% for 1992-93 when  final numbers are in, and
drop to 6.4% for 1993-94.
 
    The rate of job creation in Florida's manufacturing sector has exceeded that
of the U.S. From the beginning of 1980 through 1990, the State added over 78,700
new manufacturing  jobs, a  17.7%  increase. During  the same  period,  national
manufacturing  employment declined seven out of the  eleven years, for a loss of
1,979,900 jobs.
 
    Total non-farm employment in Florida is expected to increase 1.3% in 1992-93
and rise 4.3%  in 1993-94.  These figures,  as well  as the  figures for  income
above,  include the  post-Hurricane Andrew impact.  Trade and  services, the two
largest sources of employment in  the State, account for  more than half of  the
total non-farm employment. Employment in the service sector should experience an
increase  of 3.6% in 1992-93, and 5.6% in 1993-94. The service sector is now the
State's  largest  employment  category   comprising  30.7%  of  total   non-farm
employment.
 
    CONSTRUCTION.   The State's economy has in the past been highly dependent on
the  construction  industry   and  construction   related  manufacturing.   This
dependency  has declined in recent  years and continues to do  so as a result of
continued diversification of the  State's economy. For  example, in 1980,  total
contract  construction employment  as a share  of total  non-farm employment was
just over 7.0%, and in 1990 the share had edged downward to 6.0%. This trend  is
expected  to continue  as the State's  economy continues  to diversify. Florida,
nevertheless, has a dynamic construction industry, with single and  multi-family
housing  starts accounting for 9.48% of total  U.S. housing starts in 1991 while
the State's population is 5.3% of  the U.S. total population. Florida's  housing
starts  since 1980  have represented  an average  of 11.5%  of the  U.S.'s total
annual starts, and  except for the  recession years 1980-82,  and the  recession
beginning in 1990, Florida housing starts have exceeded 160,000 a year.
 
    A  driving  force  behind the  State's  construction industry  has  been the
State's rapid rate  of population growth.  Although the State  currently is  the
fourth  most populous  state, its annual  population growth is  now projected to
decline as the number of people moving into the State is expected to hover  near
the  mid  200,000 range  annually well  into the  1990's. This  population trend
should  provide  plenty  of  fuel  for  business  and  home  builders  to   keep
construction  activity lively in  Florida for some time  to come. However, other
factors do  influence the  level  of construction  in  the State.  For  example,
federal tax reform in 1986 and other changes to the federal income tax code have
eliminated  tax deductions for  owners of more than  two residential real estate
properties  and  have  lengthened  depreciation  schedules  on  investment   and
commercial  properties.  Economic  growth and  existing  supplies  of commercial
buildings and homes also contribute to the level of construction activity in the
State.
 
                                       25
<PAGE>
    Hurricane Andrew left some parts of south Florida devastated. Post-Hurricane
Andrew clean up and rebuilding have changed the outlook for the State's economy.
Single and  multi-family housing  starts in  1992-93 are  projected to  reach  a
combined  level of  116,800, and  to increase  to 148,100  in 1993-94. Lingering
recessionary effects on consumers  and tight credit are  two of the reasons  for
relatively  slow core construction  activity, as well  as lingering effects from
the 1986 tax reform legislation discussed above. However, construction is one of
the sectors most severely affected by Hurricane Andrew. The construction figures
above include, over  the two year  period, more than  20,000 additional  housing
starts  as  a  result of  destruction  by Hurricane  Andrew.  Total construction
expenditures are forecasted to increase 11.1% this year and increase 23.7%  next
year.
 
    TOURISM.     Tourism  is   one  of  Florida's   most  important  industries.
Approximately 39.3 million tourists  visited the State in  1991, as reported  by
the  Florida Department of  Commerce. In terms of  business activities and state
tax revenues, tourists in Florida in  1991 represented an estimated 4.4  million
additional  residents. Visitors to the  State tend to arrive  equally by air and
car. The State's tourism industry over the years has become more  sophisticated,
attracting  visitors  year-round and,  to  a degree,  reducing  its seasonality.
Tourist arrivals should be slightly negatively impacted as a result of Hurricane
Andrew, but should recover and approximate in 1993-94 the number expected  prior
to  the storm. When the final numbers are in,  it is expected that by the end of
the State's  current  fiscal  year,  41.9  million  domestic  and  international
tourists  will have visited the State, up 7.8% from the 39 million tourists that
visited Florida in 1991-92. In 1993-94, tourist arrivals should approximate 43.2
million.
 
    REVENUES AND EXPENSES.  Estimated  fiscal year 1992-93 General Revenue  plus
Working  Capital funds  available to the  State total $12,285.9  million, a 9.2%
increase over 1991-92.  This reflects a  transfer of $228.8  million, out of  an
estimated  $233.5 million in non-recurring revenue due to Hurricane Andrew, to a
hurricane relief trust fund. Of the  total General Revenue plus Working  Capital
funds  available to the  State, $12,004.1 million of  that is Estimated Revenues
(excluding the Hurricane Andrew impact),  which represents an increase of  10.1%
over  the previous  year's Estimated  Revenues. With  effective General Revenues
plus Working  Capital Fund  appropriations  at $11,914.0  million,  unencumbered
reserves  at the end of the current fiscal year are estimated at $371.9 million.
Estimated fiscal  year  1993-94  General  Revenue  plus  Working  Capital  Funds
available  total $13,490.1 million, a 9.8%  increase over 1992-93. The $13,016.1
million in Estimated Revenues  represent an increase of  8.4% over the  previous
year's  Estimated Revenues. The massive effort  to rebuild and replace destroyed
or damaged  property in  the wake  of Hurricane  Andrew is  responsible for  the
substantial  positive revenue impacts shown  here. Most of the  impact is in the
increase in the State's sales tax.
 
    In fiscal  year 1991-92,  approximately 64.0%  of the  State's total  direct
revenue  to its three operating funds was derived from State taxes, with Federal
grants and other special revenue accounting for the balance. State sales and use
tax, corporate  income  tax, and  beverage  tax amounted  to  68%, 7%,  and  5%,
respectively,  of total receipts by the  General Revenue Fund during fiscal year
1991-92. In that same year, expenditures for education, health and welfare,  and
public   safety  amounted  to  53%,  30%,  and  13.3%,  respectively,  of  total
expenditures from the General Revenue Fund.
 
    The State's sales and use tax (6%) currently accounts for the State's single
largest source of tax receipts. Sightly less  than 10% of the State's sales  and
use tax is designated for local governments and is distributed to the respective
counties  in which  collected for  use by  the counties,  and the municipalities
therein. In  addition to  this distribution,  local governments  may assess  (by
referendum)   a  0.5%  or  a  1.0%   discretionary  sales  surtax  within  their
 
                                       26
<PAGE>
county. Proceeds from  this local  option sales  tax are  earmarked for  funding
local  infrastructure  programs  and  acquiring land  for  public  recreation or
conservation or protection of natural  resources as provided under Florida  law.
Certain   charter   counties   have   other   additional   taxing   powers,  and
non-consolidated counties with  a population  in excess  of 800,000  may levy  a
local option sales tax to fund indigent health care. It alone cannot exceed 0.5%
and  when combined  with the infrastructure  surtax cannot exceed  1.0%. For the
fiscal year ended June 30,  1992, sales and use  tax receipts (exclusive of  the
tax  on gasoline  and special fuels)  totalled $8,375.5 million,  an increase of
2.7% over fiscal year 1990-91.
 
    The second largest source of State tax  receipts is the tax on motor  fuels.
However,  these revenues are almost entirely  dedicated trust funds for specific
purposes and are not included in the State's General Revenue Fund.
 
    The State imposes an alcoholic beverage wholesale tax (excise tax) on  beer,
wine,  and  liquor. This  tax  is one  of the  State's  major tax  sources, with
revenues totalling $435.2 million in fiscal year ending June 30, 1992. Alcoholic
beverage tax  receipts declined  from the  previous year's  total. The  revenues
collected from this tax are deposited into the State's General Revenue Fund.
 
    The  State imposes  a corporate  income tax.  All receipts  of the corporate
income tax are credited to the General  Revenue Fund. For the fiscal year  ended
June  30, 1992, receipts  from this source  were $801.3 million,  an increase of
14.2% from fiscal year 1990-91.
 
    The State  imposes a  documentary stamp  tax on  deeds and  other  documents
relating  to  realty,  corporate shares,  bonds,  certificates  of indebtedness,
promissory notes, wage assignments, and retail charge accounts. The  documentary
stamp tax collections totalled $472.4 million during fiscal year 1991-92, a 0.5%
increase  from the previous fiscal year. For  the fiscal year 1990-91, 76.21% of
the documentary stamp tax  revenues was deposited to  the General Revenue  Fund.
Beginning  in fiscal year 1992-93,  71.29% of these taxes  is to be deposited to
the General Revenue Fund.
 
    The State  imposes an  intangible personal  property tax  on stocks,  bonds,
including  bonds secured by liens in  Florida real property, notes, governmental
leaseholds, and certain other intangibles not secured by a lien on Florida  real
property.  The  annual  rate  of  tax  is  2  mils.  The  State  also  imposes a
non-recurring 2 mil tax on mortgages  and other obligations secured by liens  on
Florida  real  property.  In  fiscal  year  1991-92,  total  intangible personal
property tax collections were  $586.2 million, a 13.0%  increase over the  prior
year. Of the tax proceeds, 66.5% is distributed to the General Revenue Fund.
 
    The  State began its  own lottery in  1988. State law  requires that lottery
revenues be  distributed  50.0%  to the  public  in  prizes, 38.0%  for  use  in
enhancing  education, and  the balance,  12.0%, for  costs of  administering the
lottery. Fiscal  year  1991-92  lottery ticket  sales  totalled  $2.19  billion,
providing education with approximately $835.4 million.
 
    The  State's severance tax  applies to oil, gas,  and sulphur production, as
well as  the  severance  of  phosphate rock  and  other  solid  minerals.  Total
collections from severance taxes total $67.2 million during fiscal year 1991-92,
down  6.9% from the  previous year. Beginning  in fiscal year  1989-90, 60.0% of
this amount was transferred to the General Revenue Fund. The 60.0% allocation is
expected to continue.
 
    DEBT-BALANCED BUDGET REQUIREMENT.  At the end of fiscal 1992,  approximately
$4.52  billion in principal amount of debt  secured by the full faith and credit
of the State was outstanding. In addition, since July 1, 1992, the State  issued
about $274 million in principal amount of full faith and credit bonds.
 
    The  State Constitution  and statutes  mandate that  the State  budget, as a
whole, and each separate fund within the  State budget, be kept in balance  from
currently  available revenues each  fiscal year. If  the Governor or Comptroller
believe a deficit will occur in any State fund,
 
                                       27
<PAGE>
by statute, he must certify his opinion to the Administrative Commission,  which
then  is  authorized  to reduce  all  State  agency budgets  and  releases  by a
sufficient amount to  prevent a  deficit in  any fund.  Additionally, the  State
Constitution prohibits issuance of State obligations to fund State operations.
 
    LITIGATION.  Currently under litigation are several issues relating to State
actions  or State taxes that put at  risk substantial amounts of General Revenue
Fund monies.  Accordingly, there  is  no assurance  that  any of  such  matters,
individually or in the aggregate, will not have a material adverse affect on the
State's financial position.
 
    In  the wake of the  U.S. Supreme Court decisions  holding that a Hawaii law
unfairly discriminated against  out-of-state liquor producers,  suits have  been
filed  in the State's courts contesting a  similar State law (in effect prior to
1985) that seek $384 million in tax refunds. A trial court, in a ruling that was
subsequently upheld  by  the Florida  Supreme  Court,  found the  State  law  in
question  to  be unconstitutional  but  made its  ruling  operate prospectively,
thereby denying any tax refunds. The issue of whether the unconstitutionality of
the tax should be applied retroactively was decided in favor of the taxpayers by
the U.S. Supreme Court on June 4,  1990. On remand from the U.S. Supreme  Court,
the  Florida Supreme Court, on January 15, 1991, mandated further proceedings to
fashion a "clear and certain remedy" consistent with constitutional restrictions
and the opinion of the U.S. Supreme Court. The Florida Department of Revenue has
proposed to the Florida Supreme Court that the Department be allowed to  collect
back  taxes from those  who received a  tax preference under  the prior law. The
Florida Supreme  Court remanded  the matter  to the  Circuit Court  for the  2nd
Judicial  Circuit to hear arguments on the method chosen by the State to provide
a clear and certain remedy. On October  15, 1992, the Circuit Court trial  judge
orally  stated  that the  method chosen  by the  State is  unconstitutional. The
Circuit Court has not issued a written,  final order, which the State is  likely
to  appeal. An unfavorable  outcome could result  in the State  having to refund
over $340 million.
 
    Florida law provides preferential tax  treatment to insurers who maintain  a
home  office in the State. Certain  insurers challenged the constitutionality of
this tax preference  and sought a  refund of taxes  paid. Recently, the  Florida
Supreme  Court ruled  in favor of  the State.  This case and  others, along with
pending refund claims, total about $200 million.
 
    The State  maintains a  bond rating  of  Aa and  AA from  Moody's  Investors
Service  and Standard & Poor's Corporation, respectively, on the majority of its
general obligation bonds, although the rating of a particular series of  revenue
bonds  relates primarily to the project,  facility, or other revenue source from
which such series derives funds for  repayment. While these ratings and some  of
the  information  presented above  indicate that  the  State is  in satisfactory
economic health, there can be no assurance  that there will not be a decline  in
economic  conditions or that particular Florida Bonds purchased by the fund will
not be adversely affected by any such changes.
 
    The sources for the information presented above include official  statements
and  financial statements  of the  State of Florida.  While the  Sponsor has not
independently verified this information,  it has no reason  to believe that  the
information is not correct in all material respects.
 
FLORIDA TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The  following tables show the approximate taxable estimated current returns
for individuals  that are  equivalent to  tax-exempt estimated  current  returns
under  published  1994  marginal  Federal  tax  rates.  The  tables  incorporate
increased tax  rates  for higher-income  taxpayers  that were  included  in  the
Revenue Reconciliation Act of 1993. The tables illustrate what you would have to
earn on taxable investments to equal the tax-exempt estimated current return for
your  income  tax  bracket.  A  taxpayer's  marginal  tax  rate  is  affected by
 
                                       28

both his taxable  income and  his adjusted  gross income.  Locate your  adjusted
gross  and your taxable income  (which is your adjusted  gross income reduced by
any deductions and exemptions), then locate  your tax bracket based on joint  or
single  tax  filing. Read  across to  the  equivalent taxable  estimated current
return you would need to match the tax-free income.

      1 The table reflects the effect of the limitations  on itemized deductions and the deduction for personal exemptions.  They
were  designed to phase out certain benefits of these deductions for higher income taxpayers. These limitations, in effect, raise
the current maximum marginal Federal tax rate to approximately 44.0  percent for taxpayers filing a joint return and entitled  to
four  personal exemptions and to  approximately 41.0 percent for taxpayers  filing a single return  entitled to only one personal
exemption. These limitations are  subject to certain maximums,  which depend on  the number of exemptions  claimed and the  total
amount  of the taxpayer's itemized  deductions. For example, the limitation  on itemized deductions will  not cause a taxpayer to
lose more than 80% of his allowable itemized deductions, with certain exceptions.
      2 Federal tax rate reverts to 36.0% after the 80% cap on the limitation on itemized deductions has been met.
      3 Federal tax rate reverts to 39.6% after the 80% cap on the limitation on itemized deductions has been met.
</TABLE>
 
    A comparison of  tax-free and equivalent  taxable estimated current  returns
with  the returns on various  taxable investments is one  element to consider in
making an  investment  decision.  The Sponsor  may  from  time to  time  in  its
advertising  and sales materials  compare the then  current estimated returns on
the Trust and returns over specified periods on other similar Nuveen Trusts with
returns on taxable investments such as corporate or U.S. Government bonds,  bank
CD's  and  money  market accounts  or  money  market funds,  each  of  which has
investment characteristics  that  may  differ  from those  of  the  Trust.  U.S.
Government  bonds, for example, are  backed by the full  faith and credit of the
U.S. Government and bank CD's and money market accounts are insured by an agency
of the federal government. Money market accounts and money market funds  provide
stability  of principal, but pay interest at  rates that vary with the condition
of the short-term debt market. The  investment characteristics of the Trust  are
described more fully elsewhere in this Prospectus.

MASSACHUSETTS INSURED TRUST 109
    
   
    The  Portfolio of Massachusetts Insured Trust  109 consists of 6 obligations
issued by entities  located in  Massachusetts and  one obligation  issued by  an
entity  located in  the Territory  of Puerto  Rico. Two  Bonds in  the Trust are
general obligations of the governmental entities issuing them and are backed  by
the  taxing powers thereof. Five Bonds in  the Trust are payable as to principal
and interest from  the income of  a specific  project or authority  and are  not
supported  by the issuer's power to levy taxes. The sources of payment for these
Bonds are  divided as  follows: Bridge  and Toll  Road Revenue,  1; College  and
University  Revenue,  1; Health  Care Facility  Revenue,  2; Water  and/or Sewer
Revenue, 1. All of the Bonds in the Trust, as insured, are rated AAA by Standard
& Poor's Corporation and Aaa by Moody's Investors Service, Inc.
    
 
   
    At  the  Date  of  Deposit,  the  average  maturity  of  the  Bonds  in  the
Massachusetts  Insured Trust is 26.5 years. The average maturity of the Bonds in
a Trust is  calculated based upon  the stated  maturities of the  Bonds in  such
Trust  (or, with respect to Bonds for which funds or securities have been placed
in escrow to  redeem such  Bonds on  a stated call  date, based  upon such  call
date).  The average maturity  of the Bonds  in a Trust  may increase or decrease
from time to time as Bonds mature or are called or sold.
    
 
   
    Approximately 28.3% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 28.3% of the aggregate offering price of the
Bonds)    are   original    issue   discount    bonds.   See    "GENERAL   TRUST
INFORMATION--ORIGINAL ISSUE  DISCOUNT  BONDS  AND STRIPPED  OBLIGATIONS"  for  a
discussion  of the  characteristics of  such bonds  and of  the risks associated
therewith.
    
 
    Approximately 29% of  the aggregate  principal amount  of the  Bonds in  the
Trust  consists of obligations  of issuers whose  revenues are primarily derived
from services provided by hospitals or other health care facilities.
 
    For a discussion of  the risks associated with  investments in the bonds  of
various issuers, see "General Trust Information" in this section.
 
   
    The Sponsor entered into contracts to acquire the Bonds between December 21,
1993 and January 5, 1994. The following summarizes certain information about the
Bonds as of the business day prior to the Date of Deposit:

</TABLE>
 
    Neither   cost  to  Sponsor  nor  profit   (or  loss)  to  Sponsor  reflects
underwriting profits or losses received or  incurred by the Sponsor through  its
participation   in  underwriting  syndicates.  An  underwriter  or  underwriting
syndicate purchases bonds  from the issuer  on a negotiated  or competitive  bid
basis  as principal with  the motive of  marketing such bonds  to investors at a
profit. The Sponsor did not participate as  either the sole underwriter or as  a
manager  or member of a syndicate that  acted as the original underwriter of any
of the Bonds.
 
   
    Unitholders may  elect to  have interest  distributions made  on a  monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the Massachusetts Insured Trust, less estimated expenses, is estimated to accrue
at  the  rate  of  $.01439  per  Unit per  day  under  the  semi-annual  plan of
distribution, $.01434 per Unit per day under the quarterly plan of  distribution
and  $.01425 per  Unit per  day under  the monthly  plan of  distribution. It is
anticipated that  the amount  of interest  to be  distributed per  Unit in  each

year  under each plan  of distribution will initially  be substantially equal to
the Estimated Net Annual Interest Income per Unit for that plan.
 
    Details of  interest distributions  per Unit  of the  Massachusetts  Insured
Trust under the various plans appear in the following table based upon estimated
Net Annual Interest Income at the Date of Deposit:

 *  Record Dates for semi-annual distributions are May 1 and November 1; for quarterly distributions, they are February 1, May 1,
   August 1 and November 1. Record Dates for monthly distributions are the first day of each month.
(1) The first distribution will be paid to all Unitholders, regardless of the distribution plan selected.
(2) The  second distribution  under the  quarterly  distribution plan  represents a  1-month distribution;  subsequent  quarterly
    distributions will be regular 3-month distributions.
(3)  The second distribution  under the semi-annual distribution  plan represents a  1-month distribution; subsequent semi-annual
    distributions will be regular 6-month distributions.

    The accrual amounts set forth above, and  in turn the amount of interest  to
be  distributed annually per Unit, will  generally change as Bonds are redeemed,
mature or are sold.
 
TAX STATUS--MASSACHUSETTS INSURED TRUST
 
    For a discussion of the Federal tax status of income earned on Massachusetts
Insured Trust Units, see Section 11.
 
    In the opinion  of Edwards &  Angell, special Massachusetts  counsel to  the
Trust, based on rulings by the Commissioner of Revenue and under existing law:
 
        For  Massachusetts income tax purposes, each  Trust will be treated as a
    corporate trust under Section 8 of  Chapter 62 of the Massachusetts  General
    Laws  ("M.G.L.") and not  as a grantor  trust under Section  10(e) of M.G.L.
    Chapter 62.
 
        The Trust will not be held  to be engaging in business in  Massachusetts
    within  the meaning of said Section 8 and will, therefore, not be subject to
    Massachusetts income tax.
 
        Unitholders who  are  subject  to Massachusetts  income  taxation  under
    M.G.L. Chapter 62 will not be required to include their respective shares of
    the  earnings of  or distributions from  the Massachusetts  Insured Trust in
    their Massachusetts  gross  income  to  the extent  that  such  earnings  or
    distributions represent tax-exempt interest excludable from gross income for
    Federal  income tax purposes received by  the Massachusetts Insured Trust on
    obligations  issued   by   Massachusetts,  its   counties,   municipalities,
    authorities,  political subdivisions or instrumentalities or by Puerto Rico,
    the Virgin Islands, Guam, the Northern Mariana Islands or other  possessions
    of  the United States within  the meaning of Section  103(c) of the Internal
    Revenue Code of 1986, as amended ("Massachusetts Obligations").
 
        In the  case  of a  Massachusetts  Insured Trust,  Unitholders  who  are
    subject to Massachusetts income taxation under M.G.L. Chapter 62 will not be
    required   to  include  their  respective  shares  of  the  earnings  of  or
    distributions from such  Trust in  their Massachusetts gross  income to  the
    extent   that  such   earnings  or   distributions  are   derived  from  the
 
                                       32
<PAGE>
    proceeds of insurance obtained by the Sponsor of such Trust or by the issuer
    or underwriter of an obligation held  by such Trust that represent  maturing
    interest  on defaulted obligations held  by the Trustee, if  and to the same
    extent that such earnings or  distributions would have been excludable  from
    the  gross income of such  Unitholders if derived from  interest paid by the
    issuer of the defaulted obligation.
 
        Unitholders which  are corporations  subject  to taxation  under  M.G.L.
    Chapter  63  will be  required  to include  their  respective shares  of the
    earnings of or  distributions from  the Trust in  their Massachusetts  gross
    income  to the extent that such earnings or distributions represent interest
    from bonds, notes  or indebtedness  of any  state, including  Massachusetts,
    except for interest which is specifically exempted from such tax by the acts
    authorizing issuance of said Massachusetts Obligations.
 
        The  Massachusetts Insured  Trust's capital gains  and/or capital losses
    which are includable  in the  Federal gross  income of  Unitholders who  are
    subject  to  Massachusetts  income  taxation  under  M.G.L.  Chapter  62, or
    Unitholders which are corporations  subject to Massachusetts taxation  under
    M.G.L.  Chapter 63 will  be included as  capital gains and/or  losses in the
    Unitholders' Massachusetts gross  income, except for  capital gain which  is
    specifically  exempted  from  taxation  under  such  Chapters  by  the  acts
    authorizing issuance of said Massachusetts Obligations.
 
        Unitholders which are corporations subject  to tax under M.G.L.  Chapter
    63  and which  are tangible  property corporations  will not  be required to
    include the Units  when determining  the value of  their tangible  property.
    Unitholders  which are intangible property  corporations will be required to
    include the Units when determining their net worth.
 
        Gains or losses realized on sales or redemptions of Units by Unitholders
    who are subject to Massachusetts income taxation under M.G.L. Chapter 62, or
    Unitholders which are corporations subject to Massachusetts income  taxation
    under  M.G.L. Chapter  63, will be  includable in  their Massachusetts gross
    income. In  determining such  gain or  loss Unitholders  will, to  the  same
    extent required for Federal tax purposes, have to adjust their tax bases for
    their  Units  for  accrued  interest  received,  if  any,  on  Massachusetts
    Obligations delivered to  the Trustee  after the Unitholders  pay for  their
    Units,  for amortization of  premiums, if any,  on Massachusetts Obligations
    held by  the Massachusetts  Insured Trust,  and for  accrued original  issue
    discount  with respect to  each Massachusetts Obligation  which, at the time
    the Massachusetts Obligation was issued, had original issue discount.
 
        The Units of the  Trust are not  subject to any  property tax levied  by
    Massachusetts  or any political  subdivision thereof, nor  to any income tax
    levied by any such political subdivision.  They are includable in the  gross
    estate  of a deceased holder who is a resident of Massachusetts for purposes
    of the Massachusetts Estate Tax.
 
ECONOMIC FACTORS--MASSACHUSETTS
 
    Without intending  to  be complete,  the  following briefly  summarizes  the
current  financial situation, as  well as some of  the complex factors affecting
the  financial   situation,   in   the  Commonwealth   of   Massachusetts   (the
"COMMONWEALTH").  It is  derived from  sources that  are generally  available to
investors and is based in part on information obtained from various agencies  in
Massachusetts.  No independent  verification has  been made  of the  accuracy or

    There can  be no  assurance that  current or  future statewide  or  regional
economic  difficulties,  and  the  resulting  impact  on  Commonwealth  or local
governmental finances generally, will not  adversely affect the market value  of
Massachusetts  Obligations in the Trust or the ability of particular obligors to
make timely payments of debt service on (or relating to) those obligations.
 
    Since 1988,  there has  been a  significant slowdown  in the  Commonwealth's
economy,  as indicated by  a rise in  unemployment, a slowing  of its per capita
income growth and declining state  revenues. In fiscal 1991, the  Commonwealth's
expenditures  for  state  government  programs  exceeded  current  revenues, and
although fiscal 1992 revenues exceeded  expenditures, no assurance can be  given
that lower than expected tax revenues will not resume and continue.
 
    1993  FISCAL  YEAR  BUDGET.    On July  20,  1992  the  Governor  signed the
Commonwealth's budget  for  fiscal  1993.  This budget  is  based  on  estimated
budgeted  revenue and  other sources of  $14.641 billion,  including current tax
revenue estimates of $9.940 billion. Based on December 31, 1992 tax collections,
tax revenues for the fiscal 1993 budget were revised upwards on January 27, 1993
from the  original  consensus tax  estimate  of $9.685  billion.  Estimated  tax
revenues  for  fiscal 1993  are approximately  $456.4  million greater  than tax
revenues for fiscal  1992. As  modified by  legislation enacted  since July  20,
1992,  the fiscal 1993  budget provides for  estimated budgeted expenditures and
other uses of $14.976  billion, which equals the  sum of projected revenues  and
other  sources plus approximately $319.4 million of the estimated $549.4 million
positive budgetary fund balances  existing as of the  close of fiscal 1992.  The
projected  fiscal  1993  budgeted  expenditures  and  other  uses  represents an
increase of 11.6% from  fiscal 1992. The fiscal  1993 budget remains subject  to
certain  of  the Governor's  line-item vetoes,  which may  be overridden  by the
legislature.
 
    With regard to revenues, the fiscal  1993 budget depends on certain  non-tax
revenue  sources, the availability of which is subject to certain contingencies.
The fiscal  1993  budget assumes  continued  federal reimbursements  related  to
uncompensated  care  payments,  which  is expected  to  be  approximately $212.7
million in fiscal 1993.
 
    The fiscal 1993  budget also assumes  that the sale  of certain assets  will
generate  approximately $45.0  million in  non-tax revenues,  however, there are
currently no agreements to sell  such assets and the market  for some or all  of
such  assets  in unfavorable.  The fiscal  1993 budget  also assumes  receipt of
approximately $80.0  million from  the  Massachusetts Water  Resource  Authority
("MWRA")  under an arrangement which would, among other things, relieve the MWRA
of certain comparable future financial commitments to the Commonwealth.
 
    1992 FISCAL YEAR.  The  Commonwealth's budgeted expenditures and other  uses
were  approximately $13.420 billion  in fiscal 1992, which  is $238.7 million or
1.7% lower than fiscal  1991 budgeted expenditures.  Final fiscal 1992  budgeted
expenditures  were $300  million more  than the  initial July  1991 estimates of
budgetary expenditures,  due in  part  to increases  in certain  human  services
programs,  including an increase of $268.7  million for the Medicaid program and
$50.0 million  for  mental  retardation consent  decree  requirements.  Budgeted
revenues and other sources for fiscal 1992 totaled approximately $13.728 billion
(including   tax  revenues  of  $9.484   billion),  reflecting  an  increase  of
approximately 0.7% from  fiscal 1991  to 1992  and an  increase of  5.4% in  tax
revenues  for the same period.  Overall, fiscal 1992 is  estimated to have ended
with an excess of revenues and other sources over expenditures and other uses of
$312.3 million. After payment in full of the quarterly distribution of local aid
to   the   Commonwealth's    cities   and   towns    ("LOCAL   AID")   in    the
 
                                       34
<PAGE>
amount  of $514.0 million due on June 30, 1992, retirement of the Commonwealth's
outstanding commercial  paper  (except for  approximately  $50 million  of  bond
anticipation  notes) and  certain other  short term  borrowings, as  of June 30,
1992, the end of fiscal 1992,  the Commonwealth showed a year-end cash  position
of  approximately $731 million, as compared with the Commonwealth's cash balance
of $182.3 million at the end of fiscal 1991.
 
    1991 FISCAL YEAR.  Budgeted expenditures for fiscal 1991 were  approximately
$13.659 billion, as against budgeted revenues and other sources of approximately
$13.634  billion. The Commonwealth  suffered an operating  loss of approximately
$21.2 million. Application of the adjusted  fiscal 1990 fund balances of  $258.3
resulted  in  a  fiscal 1991  budgetary  surplus  of $237.1  million.  State law
requires that approximately $59.2 million of the fiscal year ending balances  of
$237.1  million be placed in the Stabilization  Fund, a reserve from which funds
can be appropriated (i) to make up any difference between actual state  revenues
in  any fiscal year  in which actual  revenues fall below  the allowable amount,
(ii) to replace state and local losses by federal funds or (iii) for any  event,
as  determined by the legislature, which threatens the health, safety or welfare
of the  people  or the  fiscal  stability of  the  Commonwealth or  any  of  its
political subdivisions.
 
    Upon  taking office in January  1991, the new Governor  proposed a series of
legislative and  administrative  actions, including  withholding  of  allotments
under  Section 9C of Chapter  29 of the General  Laws, intended to eliminate the
projected deficits.  The  new Governor's  review  of the  Commonwealth's  budget
indicated  projected spending of $14.105 billion  with an estimated $850 million
in budget balancing measures that would be  needed prior to the close of  fiscal
1991.  At that time, estimated tax revenues were revised to $8.845 billion, $903
million less than was estimated at the time the fiscal 1991 budget was  adopted.
The  Legislature  adopted a  number of  the  Governor's recommendations  and the
Governor took certain administrative actions not requiring legislative approval,
including the adoption of a state employee furlough program. It is estimated  by
the  Commonwealth that spending reductions  achieved through savings initiatives
and withholding of  allotments total approximately  $484.3 million in  aggregate
for  fiscal  1991.  However,  these  savings  and  reductions  may  be  impacted
negatively by  litigation pursued  by third  parties concerning  the  Governor's
action under Section 9C of Chapter 29 of the General Laws and with regard to the
state employee furlough program.
 
    In  addition, the new administration  in May 1991 filed  an amendment to its
Medicaid state  plan that  enables  it to  claim  50% federal  reimbursement  on
uncompensated  care payments  for certain  hospitals in  the Commonwealth.  As a
result, in fiscal 1991 the Commonwealth obtained additional non-tax revenues  in
the  form  of  federal reimbursements  equal  to approximately  $513  million on
account of uncompensated care payments. This reimbursement claim was based  upon
recent  amendments of federal law contained in the Omnibus Budget Reconciliation
Act  of  1990  and,  consequently,  on  relatively  undeveloped  federal   laws,
regulations  and guidelines. At the request of the federal Health Care Financing
Administration, the Office of Inspector General of the United States  Department
of  Health and Human Services  has commenced an audit  of the reimbursement. The
administration, which had  reviewed the  matter with the  Health Care  Financing
Administration   prior  to   claiming  the  reimbursement,   believes  that  the
Commonwealth will prevail in  the audit. If the  Commonwealth does not  prevail,
the  Commonwealth  would have  the  right to  contest  an appeal,  but  could be
required to pay all or part of Medicaid reimbursements with interest and to have
such amount deducted from future reimbursement payments.
 
    1990, 1989 AND 1988 FISCAL YEARS.  In July 1989, the former Governor  vetoed
certain provisions included in the budget legislation for fiscal 1990, including
approximately  $273 million  of the  fiscal 1990  appropriations, including $100
million for Local Aid. One of the
 
                                       35
<PAGE>
Governor's vetoes occasioned  a default by  the Commonwealth on  a September  1,
1989  payment  of  $2.5  million  on  a  general  obligation  contract  with the
Massachusetts Community Development Finance Corporation to which its full  faith
and  credit had been pledged, which payment was made on September 17, 1990 after
a supplemental appropriation  was proposed  by the  Governor and  passed by  the
legislature.  The legislature  overrode the Governor's  veto of  $100 million of
Local Aid and the Governor then indicated that he was withholding the  allotment
for  such  expenditure. The  Supreme Judicial  Court invalidated  the Governor's
withholding of $210 million of appropriated funds for certain Local Aid purposes
in May 1990.
 
    Budgeted expenditures for fiscal 1988,  1989 and 1990 totaled  approximately
$11.6  billion, $12.6 billion and $13.3 billion, respectively. Budgeted revenues
for fiscal  1988,  1989 and  1990  totaled approximately  $11.3  billion,  $12.0
billion and $12.0 billion, respectively.
 
    EMPLOYMENT.   Reversing  a trend of  relatively low  unemployment during the
early  and  mid  1980s,  the  Massachusetts  unemployment  rate  has   increased
significantly   during  the  last  three   years  to  where  the  Commonwealth's
unemployment rate exceeds the national  unemployment rate. In 1989, the  average
Massachusetts unemployment rate was 4.0%, representing an 0.8% increase over the
average  1987 unemployment  rate, while  the average  United States unemployment
rate was 5.3%, representing a 0.9% decrease over the average 1987 United  States
unemployment  rate. During  1990, the Massachusetts  unemployment rate increased
from 4.5%  in January  to 6.1%  in  July to  6.7% in  August. During  1991,  the
Massachusetts  unemployment rate averaged  9.0% while the  average United States
unemployment rate was 6.7%. The Massachusetts unemployment rate in October  1992
was   8.4%,  down  from  8.6%  for  September  1992.  Other  factors  which  may
significantly and  adversely  affect the  employment  rate in  the  Commonwealth
include  the recently announced proposal by  the Clinton Administration to close
United  States  military  bases  and  reduce  federal  government  spending   on
defense-related  industries. Due to this and  other considerations, there can be
no assurances that  unemployment in the  commonwealth will not  increase in  the
future.
 
    DEBT  RATINGS.   S&P  currently rates  the Commonwealth's  uninsured general
obligation bonds at A, having upgraded the rating from BBB on September 9, 1992.
At the same time, S&P upgraded the rating of state and agency notes from SP2  to
SP1.  In raising  the ratings, S&P  cited the  Commonwealth's improved financial
status as key to the  upgrade. Prior to these  actions by S&P, the  Commonwealth
had experienced a steady decline in its S&P rating, with its most recent decline
beginning in May 1989, when S&P lowered its rating on the Commonwealth's general
obligation  bonds  and  other  Commonwealth  obligations  from  AA+  to  AA  and
continuing a series of further reductions until March 1992, when the rating  was
affirmed at BBB.
 
    Moody's  currently  rates  the Commonwealth's  uninsured  general obligation
bonds at A, having upgrade the rating from Baa on September 9, 1992. Moody's, in
raising the rating on  the bonds, pointed to  the Commonwealth's application  of
conservative  revenue assumptions and  efforts to impose  spending discipline as
having reduced the state's financial vulnerability and restored fiscal  control.
Prior to this increase, the Commonwealth had experienced a steady decline in its
rating by Moody's since May 1989. In May 1989, Moody's lowered its rating on the
Commonwealth's  notes from MIG-1 to MIG-2,  and its rating on the Commonwealth's
commercial paper  from  P-1  to  P-2.  On June  21,  1989  Moody's  reduced  the
Commonwealth's  general obligation  rating from Aa  to A. On  November 15, 1989,
Moody's reduced the rating on the  Commonwealth's general obligations from A  to
Baa1,  citing the Commonwealth's lowering of  revenue estimates, its fiscal year
1990 deficit and to the legislature's apparent lack of consensus on how to  deal
with  it. On  March 9,  1990, Moody's reduced  the rating  of the Commonwealth's
general   obligation    bonds   from    Baa1    to   Baa,    citing    "extended
 
                                       36
<PAGE>
inaction"  in resolving the Commonwealth's growing  budget deficit. There can be
no assurance that these ratings will continue.
 
    In recent  years, the  Commonwealth and  certain of  its public  bodies  and
municipalities have faced serious financial difficulties which have affected the
credit  standing  and borrowing  abilities of  Massachusetts and  its respective
entities and may have contributed to higher interest rates on debt  obligations.
The continuation of, or an increase in, such financial difficulties could result
in  declines  in  the market  values  of,  or default  on,  existing obligations
including Massachusetts Obligations  in the  Trust. Should there  be during  the
term  of  the Trust  a financial  crisis relating  to Massachusetts,  its public
bodies or municipalities, the market value and marketability of all  outstanding
bonds  issued by the  Commonwealth and its  public authorities or municipalities
including the Massachusetts Obligations in the Trust and interest income to  the
Trust could be adversely affected.
 
    TOTAL  BOND  AND  NOTE  LIABILITIES.    The  total  general  obligation bond
indebtedness of the Commonwealth  as of January 1,  1993 was approximately  $7.9
billion.  There  were also  outstanding  approximately $339  million  in general
obligation notes and other  short term general obligation  debt. The total  bond
and  note  liabilities of  the  Commonwealth as  of  January 1,  1993, including
guaranteed bond and contingent liabilities, was approximately $12.4 billion.
 
    DEBT SERVICE.    During  the  1980s,  capital  expenditures  were  increased
substantially,  which  has had  a short  term impact  on the  cash needs  of the
Commonwealth and also  accounts for a  significant rise in  debt service  during
that  period. Payments for debt service on Commonwealth general obligation bonds
and notes have risen at an average  annual rate of 18.7% from $563.7 million  in
fiscal 1988 to an estimated $942.3 million in fiscal 1991. Debt service payments
in  fiscal  1992 were  $898.3  million. Debt  service  payments for  fiscal 1992
reflect a $261 million one-time reduction  achieved as a result of the  issuance
of  the refunding bonds in September and October 1991. Debt service expenditures
are projected to be $1.195 billion for fiscal 1993 and $1.311 billion for fiscal
1994. The amounts  represented do not  include debt service  on notes issued  to
finance  the  fiscal  1989  deficit and  certain  Medicaid  related liabilities,
certain debt service contract assistance to the Massachusetts Bay Transportation
Authority, the Massachusetts Convention  Center Authority and the  Massachusetts
Government  Land  Bank, as  well as  grants to  municipalities under  the school
building assistance program  to defray a  portion of the  debt service costs  on
local school bonds.
 
    In  January 1990, legislation was  passed to impose a  limit on debt service
beginning in  fiscal  1991,  providing  that  no more  than  10%  of  the  total
appropriations  in any fiscal year  may be expended for  payment of interest and
principal on general obligation debt (excluding the Fiscal Recovery Bonds).  The
percentage  of total appropriations  expended from the  budgeted operating funds
for debt service (excluding  debt service on Fiscal  Recovery Bonds) for  fiscal
1992 is 4.9% which is projected to increase to 6.1% in fiscal 1993.
 
    CERTAIN   LIABILITIES.    Among  the  material  future  liabilities  of  the
Commonwealth are  significant unfunded  general  liabilities of  its  retirement
systems  and a program to fund such  liabilities; a program whereby, starting in
1978, the  Commonwealth began  assuming full  financial responsibility  for  all
costs  of  the administration  of  justice within  the  Commonwealth; continuing
demands to raise aggregate aid to cities, towns, schools and other districts and
transit authorities above current levels;  and Medicaid expenditures which  have
increased each year since the program was initiated. The Commonwealth has signed
consent  decrees to continue  improving mental health care  and programs for the
mentally retarded in
 
                                       37
<PAGE>
order to meet federal  standards, including those  governing receipt of  federal
reimbursements  under  various programs,  and the  parties  in those  cases have
worked cooperatively to resolve the disputed issues.
 
    As a  result of  comprehensive legislation  approved in  January, 1988,  the
Commonwealth  is  required,  beginning in  fiscal  1989 to  fund  future pension
liabilities currently and  to amortize the  Commonwealth's unfunded  liabilities
over  40 years. Total pension costs increased  at an average annual rate of 5.8%
from $600.2  million  in fiscal  1988  to $751.5  million  in fiscal  1992.  The
estimated pension costs (inclusive of current benefits and pension reserves) for
fiscal  year 1993  are $873.8  million, representing  an increase  of 16.2% over
fiscal 1992 expenditures.
 
    LITIGATION.   The  Commonwealth is  engaged  in various  lawsuits  involving
environmental  and related  laws, including an  action brought on  behalf of the
U.S. Environmental Protection Agency alleging violations of the Clean Water  Act
and  seeking to enforce  the clean-up of  Boston Harbor. The  MWRA, successor in
liability  to  the  Metropolitan   District  Commission,  has  assumed   primary
responsibility  for developing  and implementing  a court-approved  plan for the
construction of the  treatment facilities necessary  to achieve compliance  with
federal  requirements. Under the Clean Water Act, the Commonwealth may be liable
for costs of compliance in these or any other Clean Water cases if the MWRA or a
municipality is  prevented from  raising  revenues necessary  to comply  with  a
judgment. The MWRA currently projects that the total cost of construction of the
treatment  facilities  required under  the court's  order is  approximately $3.5
billion in current dollars.
 
    The Massachusetts Hospital Association has brought an action challenging  an
element  of  the  Medicaid  rate-setting  methodologies  for  hospitals.  If the
plaintiff  hospitals  are  successful,  the  Commonwealth  may  face  additional
liabilities  on  the order  of $70  million  to $100  million. The  parties have
recently agreed to a  process of settlement and  payment of fiscal 1988  through
1991 claims, with payment to be made in fiscal 1993.
 
    There  are  also  actions  pending in  which  recipients  of  human services
benefits, such as welfare  recipients, the mentally  retarded, the elderly,  the
handicapped,  children, residents of state  hospitals and inmates of corrections
institutions, seek  expanded  levels  of  services and  benefits  and  in  which
providers  of services to such recipients challenge  the rates at which they are
reimbursed by  the Commonwealth.  To  the extent  that  such actions  result  in
judgments requiring the Commonwealth to provide expanded services or benefits or
pay  increased  rates, additional  operating and  capital expenditures  might be
needed to implement such judgments.
 
    In December, 1988, nine  municipalities of the  Commonwealth which claim  to
own  substantial interests in a nuclear  power plant in Seabrook, New Hampshire,
filed suit  against the  Commonwealth, the  Governor, the  Attorney General  and
other  state  officials  claiming  damages  arising  from  their  opposition  to
licensure of the plant.  The municipalities allege damages  in the amount of  $1
billion. The Commonwealth's motion to dismiss was allowed, but the plaintiffs in
that case have appealed and the case is under advisement in the Appeals Court.
 
    In  addition there are several tax  matters in litigation which could result
in significant refunds to taxpayers if decisions unfavorable to the Commonwealth
are rendered.  The amount  of taxes  and interest  at issue  in those  cases  is
approximately $195 million.
 
    A  variety of  other civil suits  pending against the  Commonwealth may also
affect its future  liabilities. These include  challenges to the  Commonwealth's
allocation  of school aid under Section 9C of Chapter 29 of the General Laws and
to adopt a state employee furlough program. No prediction is possible as to  the
ultimate outcome of these proceedings.
 
                                       38
<PAGE>
    Many  factors, in addition  to those cited  above, do or  may have a bearing
upon the financial condition of the Commonwealth, including social and  economic
conditions, many of which are not within the control of the Commonwealth.
 
    EXPENDITURE  AND TAX LIMITATION  MEASURES.  Limits  have been established on
state tax revenues by legislation approved  by the Governor on October 25,  1986
and  by an initiative petition  approved by the voters  on November 4, 1986. The
Executive Office for Administration and  Finance currently estimates that  state
tax  revenues will not reach the limit imposed by either the initiative petition
or the legislative enactment in fiscal 1992.
 
    Proposition 2 1/2, passed by the voters in 1980, led to large reductions  in
property  taxes, the  major source  of income  for cities  and towns,  and large
increases in state aid to offset such revenue losses. According to the Executive
Office for Administration and Finance, all of the 351 cities and towns have  now
achieved  a property  tax level of  no more  than 2.5% of  full property values.
Under the terms of Proposition 2 1/2, the property tax levy can now be increased
annually for all cities and towns, almost all by 2.5% of the prior fiscal year's
tax  levy  plus  2.5%  of  the  value  of  new  properties  and  of  significant
improvements  to  property.  Legislation  has also  been  enacted  providing for
certain local  option  taxes.  A  voter  initiative  petition  approved  at  the
statewide  general election in November, 1990 further regulates the distribution
of Local Aid of no  less than 40% of  collections from individual income  taxes,
sales  and  use taxes,  corporate excise  taxes,  and the  balance of  the state
lottery  fund.  If   implemented  in  accordance   with  its  terms   (including
appropriation  of the  necessary funds),  the petition  as approved  would shift
several hundred million dollars to direct Local Aid.
 
    OTHER TAX MEASURES.   To provide  revenue to  pay debt service  on both  the
deficit  and  Medicaid-related borrowings  and to  fund certain  direct Medicaid
expenditures, legislation  was enacted  imposing an  additional tax  on  certain
types  of personal income for 1989 and 1990 taxable years at rates of 0.375% and
0.75% respectively, effectively raising the tax  rate of 1989 from 5% to  5.375%
and  for 1990 to 5.75%. Recent legislation has effectively further increased tax
rates to 5.95% for  tax year 1990 to  6.25% for tax year  1991 and returning  to
5.95%  for tax year 1992 and subsequent tax  years. The tax is applicable to all
personal  income   except  income   derived  from   dividends,  capital   gains,
unemployment  compensation,  alimony,  rent, interest,  pensions,  annuities and
IRA/Keogh distributions.  The  income  tax rate  on  other  interest  (excluding
interest  on obligations of  the United States  and of the  Commonwealth and its
subdivisions), dividends  and net  capital  gains (after  a 50%  reduction)  was
increased  from 10% to 12%  for tax year 1990  and subsequent years, by recently
enacted legislation.
 
    OTHER ISSUERS OF  MASSACHUSETTS OBLIGATIONS.   There are a  number of  state
agencies, instrumentatlities and political subdivisions of the Commonwealth that
issue  Municipal Obligations, some  of which may  be conduit revenue obligations
payable from  payments from  private borrowers.  These entities  are subject  to
various  economic  risks  and  uncertainties,  and  the  credit  quality  of the
securities issued  by them  may vary  considerably from  the credit  quality  of
obligations  backed by the full faith and  credit of the Commonwealth. The brief
summary above does not address, nor does it attempt to address, any difficulties
and  the  financial   situations  of  those   other  issuers  of   Massachusetts
Obligations.
 
MASSACHUSETTS TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The  following tables show the approximate taxable estimated current returns
for individuals  that are  equivalent to  tax-exempt estimated  current  returns
under  combined Federal and  state taxes, using  published 1994 marginal Federal
tax rates and marginal state tax  rates currently available and scheduled to  be
in  effect.  The  tables  incorporate  increased  tax  rates  for  higher-income
taxpayers that were  included in  the Revenue  Reconciliation Act  of 1993.  For
cases  in which more than one state  bracket falls within a Federal bracket, the
 
                                       39
<PAGE>
highest state bracket is combined with  the Federal bracket. The combined  state
and  Federal tax  brackets shown  reflect the fact  that state  tax payments are
currently deductible for Federal  tax purposes. The  tables illustrate what  you
would  have to  earn on  taxable investments  to equal  the tax-exempt estimated
current return for your  income tax bracket. A  taxpayer's marginal tax rate  is
affected  by both his taxable income and  his adjusted gross income. Locate your
adjusted gross and  your taxable  income (which  is your  adjusted gross  income
reduced by any deductions and exemptions), then locate your tax bracket based on
joint  or single  tax filing.  Read across  to the  equivalent taxable estimated
current return you would need to match the tax-free income.

      1 The table reflects the effect of the limitations  on itemized deductions and the deduction for personal exemptions.  They
were  designed to phase out certain benefits of these deductions for higher income taxpayers. These limitations, in effect, raise
the current maximum marginal Federal tax rate to approximately 44.0  percent for taxpayers filing a joint return and entitled  to
four  personal exemptions and to  approximately 41.0 percent for taxpayers  filing a single return  entitled to only one personal
exemption. These limitations are  subject to certain maximums,  which depend on  the number of exemptions  claimed and the  total
amount  of the taxpayer's itemized  deductions. For example, the limitation  on itemized deductions will  not cause a taxpayer to
lose more than 80% of his allowable itemized deductions, with certain exceptions.
      2 Federal tax rate reverts to 36.0% after the 80% cap on the limitation on itemized deductions has been met.
      3 Federal tax rate reverts to 39.6% after the 80% cap on the limitation on itemized deductions has been met.
</TABLE>
 
    A comparison of  tax-free and equivalent  taxable estimated current  returns
with  the returns on various  taxable investments is one  element to consider in
making an  investment  decision.  The Sponsor  may  from  time to  time  in  its
advertising  and sales materials  compare the then  current estimated returns on
the Trust and returns over specified periods on other similar Nuveen Trusts with
returns on taxable investments such as corporate or U.S. Government bonds,  bank
CD's  and  money  market accounts  or  money  market funds,  each  of  which has
investment characteristics  that  may  differ  from those  of  the  Trust.  U.S.
Government  bonds, for example, are  backed by the full  faith and credit of the
U.S. Government and bank CD's and money market accounts are insured by an agency
of the federal government. Money market accounts and money market funds  provide
stability  of principal, but pay interest at  rates that vary with the condition
of the short-term debt market. The  investment characteristics of the Trust  are
described more fully elsewhere in this Prospectus.

NEW JERSEY INSURED TRUST 171
    
 
   
    The  Portfolio of  New Jersey  Insured Trust  171 consists  of 7 obligations
issued by entities located in New Jersey and one obligation issued by an  entity
located  in the Territory of  Puerto Rico. Three Bonds  in the Trust are general
obligations of the  governmental entities  issuing them  and are  backed by  the
taxing  powers thereof. Five Bonds in the  Trust are payable as to principal and
interest from  the  income  of a  specific  project  or authority  and  are  not
supported  by the issuer's power to levy taxes. The sources of payment for these
Bonds are divided as follows: Electrical System Revenue, 1; Health Care Facility
Revenue, 2; Transportation Facility Revenue,  1; Water and/or Sewer Revenue,  1.
All  of the Bonds in the  Trust, as insured, are rated  AAA by Standard & Poor's
Corporation and Aaa by Moody's Investors Service, Inc.
    
 
   
    At the Date of Deposit, the average maturity of the Bonds in the New  Jersey
Insured  Trust is 25.2  years. The average maturity  of the Bonds  in a Trust is
calculated based upon the stated maturities of the Bonds in such Trust (or, with
respect to Bonds for  which funds or  securities have been  placed in escrow  to
redeem such Bonds on a stated call date, based upon such call date). The average
maturity  of the Bonds in a Trust may  increase or decrease from time to time as
Bonds mature or are called or sold.
    
 
   
    Approximately 17.9% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 15.4% of the aggregate offering price of the
Bonds)  are original issue discount obligations. Certain of these original issue
discount obligations, amounting to  5.1% of the  aggregate principal amount  and
2.5%  of  the aggregate  offering price  of the  Bonds in  the Trust,  are "zero
coupon" bonds. See "GENERAL TRUST INFORMATION--ORIGINAL ISSUE DISCOUNT BONDS AND
STRIPPED  OBLIGATIONS"  for  a  discussion   of  the  characteristics  of   such
obligations and of the risks associated therewith.
    
 
    Approximately  30% of  the aggregate  principal amount  of the  Bonds in the
Trust consists of obligations  of issuers whose  revenues are primarily  derived
from services provided by hospitals or other health care facilities.
 
    For  a discussion of the  risks associated with investments  in the bonds of
various issuers, see "General Trust Information" in this section.
 
   
    The Sponsor entered into contracts to acquire the Bonds between December 30,
1993 and January 4, 1994. The following summarizes certain information about the
Bonds as of the business day prior to the Date of Deposit:

</TABLE>
 
    Neither  cost  to  Sponsor  nor   profit  (or  loss)  to  Sponsor   reflects
underwriting  profits or losses received or  incurred by the Sponsor through its
participation  in  underwriting  syndicates.  An  underwriter  or   underwriting
syndicate  purchases bonds  from the issuer  on a negotiated  or competitive bid
basis as principal with  the motive of  marketing such bonds  to investors at  a
profit.  The Sponsor did not participate as  either the sole underwriter or as a
manager or member of a syndicate that  acted as the original underwriter of  any
of the Bonds.
 
   
    Unitholders  may elect  to have  interest distributions  made on  a monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the New Jersey Insured Trust, less estimated expenses, is estimated to accrue at
the rate of $.01369 per Unit per
    
 
                                       42

day under the semi-annual plan of  distribution, $.01364 per Unit per day  under
the  quarterly  plan of  distribution and  $.01355  per Unit  per day  under the
monthly plan of distribution. It is  anticipated that the amount of interest  to
be  distributed  per Unit  in each  year  under each  plan of  distribution will
initially be substantially equal to the Estimated Net Annual Interest Income per
Unit for that plan.
    
 
    Details of interest distributions per Unit  of the New Jersey Insured  Trust
under  the various plans appear in the  following table based upon estimated Net
Annual Interest Income at the Date of Deposit:

 * Record Dates for semi-annual distributions are May 1 and November 1; for quarterly distributions, they are February 1, May  1,
   August 1 and November 1. Record Dates for monthly distributions are the first day of each month.
(1) The first distribution will be paid to all Unitholders, regardless of the distribution plan selected.
(2)  The  second distribution  under the  quarterly distribution  plan  represents a  1-month distribution;  subsequent quarterly
    distributions will be regular 3-month distributions.
(3) The second distribution  under the semi-annual  distribution plan represents a  1-month distribution; subsequent  semi-annual
    distributions will be regular 6-month distributions.

    The  accrual amounts set forth above, and  in turn the amount of interest to
be distributed annually per Unit, will  generally change as Bonds are  redeemed,
mature or are sold.
 
TAX STATUS--NEW JERSEY INSURED TRUST
 
    For  a discussion of the  Federal tax status of  income earned on New Jersey
Insured Trust Units, see Section 11.
 
    The assets of the New Jersey Insured Trust will consist of  interest-bearing
obligations  issued by  or on behalf  of the  State of New  Jersey and counties,
municipalities,  authorities  and  other  political  subdivisions  thereof,  and
certain  territories  of the  United States,  including  Puerto Rico,  Guam, the
Virgin Islands and the Northern Mariana Islands (the "New Jersey Bonds").
 
    In the  opinion of  Pitney, Hardin,  Kipp &  Szuch, special  counsel to  the
Series for New Jersey tax matters, under existing law:
 
        The  New Jersey Insured Trust  will be recognized as  a Trust and not an
    association taxable as a corporation. The New Jersey Insured Trust will  not
    be  subject to  the New  Jersey Corporation Business  Tax or  the New Jersey
    Corporation Income Tax.
 
        With respect to the non-corporate  Unitholders who are residents of  New
    Jersey,  the income of the  New Jersey Insured Trust  will be treated as the
    income of such Unitholders under the  New Jersey Gross Income Tax.  Interest
    on  the underlying New Jersey  Bonds which is exempt  from tax under the New
    Jersey Gross Income Tax  Law when received by  the New Jersey Insured  Trust
    will  retain  its  status as  tax-exempt  interest when  distributed  to the
    Unitholders.
 
        A non-corporate Unitholder will not be  subject to the New Jersey  Gross
    Income  Tax on any  gain realized either  when the New  Jersey Insured Trust
    disposes of a  New Jersey Bond  (whether by sale,  exchange, redemption,  or
    payment at maturity) or when the
 
                                       43
<PAGE>
    Unitholder redeems or sells his Units. Any loss realized on such disposition
    may  not be  utilized to  offset gains  realized by  such Unitholder  on the
    disposition of assets the gain on which  is subject to the New Jersey  Gross
    Income Tax.
 
        Units  of the New Jersey Insured Trust may  be taxable on the death of a
    Unitholder under the  New Jersey  Transfer Inheritance  Tax Law  or the  New
    Jersey Estate Tax Law.
 
        If  a Unitholder is a corporation  subject to the New Jersey Corporation
    Business Tax or New Jersey Corporation  Income Tax, interest from the  Bonds
    in  the New Jersey Insured Trust which is allocable to such corporation will
    be includable  in its  entire net  income  for purposes  of the  New  Jersey
    Corporation  Business Tax  or New  Jersey Corporation  Income Tax,  less any
    interest expense  incurred  to carry  such  investment to  the  extent  such
    interest  expense has not been deducted in computing Federal taxable income.
    Net gains derived by such corporation  on the disposition of the New  Jersey
    Bonds  by the New  Jersey Insured Trust  or on the  disposition of its Units
    will be included in  its entire net  income for purposes  of the New  Jersey
    Corporation Business Tax or New Jersey Corporation Income Tax.
 
ECONOMIC FACTORS--NEW JERSEY
 
    As  described above, the New Jersey Insured Trust consists of a portfolio of
New Jersey Bonds. The Trust is  therefore susceptible to political, economic  or
regulatory  factors affecting  issuers of  the New  Jersey Bonds.  The following
information provides  only  a brief  summary  of  some of  the  complex  factors
affecting  the financial  situation in New  Jersey (the "State")  and is derived
from sources that  are generally available  to investors and  is believed to  be
accurate.  It is based  in part on  information obtained from  various State and
local agencies in New Jersey. No  independent verification has been made of  any
of the following information.
 
    New  Jersey is the ninth largest state  in population and the fifth smallest
in land area. With an  average of 1,050 people per  square mile, it is the  most
densely  populated of all the states.  The State's economic base is diversified,
consisting of a variety of  manufacturing, construction and service  industries,
supplemented by rural areas with selective commercial agriculture. Historically,
New Jersey's average per capita income has been well above the national average,
and  in 1992  the State ranked  second among  the states in  per capita personal
income ($26,457).
 
    The New Jersey Economic  Policy Council, a statutory  arm of the New  Jersey
Department  of Commerce  and Economic  Development, has  reported in  NEW JERSEY
ECONOMIC INDICATORS,  a monthly  publication  of the  New Jersey  Department  of
Labor,  Division of Labor Market and Demographic Research, that in 1988 and 1989
employment in  New Jersey's  manufacturing  sector failed  to benefit  from  the
export  boom experienced by many Midwest states and the State's service sectors,
which had  fueled the  State's  prosperity since  1982,  lost momentum.  In  the
meantime,  the prolonged fast growth in the State in the mid 1980s resulted in a
tight labor market situation, which has led to relatively high wages and housing
prices. This  means  that,  while  the  incomes  of  New  Jersey  residents  are
relatively  high,  the State's  business sector  has  become more  vulnerable to
competitive pressures.
 
    The onset of  the national recession  (which officially began  in July  1990
according to the National Bureau of Economic Research) caused an acceleration of
New  Jersey's job  losses in  construction and  manufacturing. In  addition, the
national recession  caused an  employment downturn  in such  previously  growing
sectors  as wholesale trade,  retail trade, finance,  utilities and trucking and
warehousing.  Reflecting   the   downturn,   the   rate   of   unemployment   in
 
                                       44
<PAGE>
   
the  State  rose from  a low  of 3.6%  during the  first quarter  of 1989  to an
estimated 6.2% in  November 1993, which  is lower than  the national average  of
6.4%  in November 1993. Economic recovery is likely to be slow and uneven in New
Jersey, with unemployment receding  at a correspondingly slow  pace, due to  the
fact  that some sectors may  lag due to continued  excess capacity. In addition,
employers even in rebounding  sectors can be expected  to remain cautious  about
hiring  until they  become convinced that  improved business  will be sustained.
Also,  certain  firms   will  continue   to  merge  or   downsize  to   increase
profitability.
    
 
    DEBT  SERVICE. The primary method for State financing of capital projects is
through the sale of the general obligation  bonds of the State. These bonds  are
backed  by the full faith and credit of the State tax revenues and certain other
fees are pledged to  meet the principal and  interest payments and if  provided,
redemption premium payments, if any, required to repay the bonds. As of June 30,
1993,  there was  a total  authorized bond  indebtedness of  approximately $8.98
billion, of which  $3.6 billion  was issued  and outstanding,  $4.0 billion  was
retired  (including bonds for which provision  for payment has been made through
the sale and issuance  of refunding bonds) and  $1.38 billion was unissued.  The
debt  service obligation for such outstanding indebtedness is $119.9 million for
Fiscal Year 1994.
 
    NEW JERSEY'S BUDGET AND APPROPRIATION SYSTEM. The State operates on a fiscal
year beginning July 1 and ending June 30. At the end of Fiscal Year 1989,  there
was  a  surplus in  the  State's general  fund (the  fund  into which  all State
revenues not  otherwise  restricted by  statute  are deposited  and  from  which
appropriations  are made)  of $411.2  million. At the  end of  Fiscal Year 1990,
there was a surplus in the general fund of $1 million. At the end of Fiscal Year
1991, there was a surplus in the general fund of $1.4 million. New Jersey closed
its Fiscal Year 1992 with a surplus of $760.8 million. It is estimated that  New
Jersey closed its Fiscal Year 1993 with a surplus of $361.3 million.
 
    In  order  to  provide additional  revenues  to balance  future  budgets, to
redistribute school aid and  to contain real property  taxes, on June 27,  1990,
and  July  12,  1990, Governor  Florio  signed  into law  legislation  which was
estimated to raise approximately $2.8 billion in additional taxes (consisting of
$1.5 billion in  sales and  use taxes  and $1.3  billion in  income taxes),  the
biggest  tax hike in New Jersey history. There can be no assurance that receipts
and collections of such taxes will meet such estimates.
 
    The first  part of  the tax  hike  took effect  on July  1, 1990,  with  the
increase in the State's sales and use tax rate from 6% to 7% and the elimination
of  exemptions for certain  products and services not  previously subject to the
tax, such as telephone calls, paper products (which has since been  reinstated),
soaps  and detergents, janitorial services,  alcoholic beverages and cigarettes.
At the  time  of  enactment, it  was  projected  that these  taxes  would  raise
approximately  $1.5 billion in additional  revenue. Projections and estimates of
receipts from sales  and use taxes,  however, have been  subject to variance  in
recent fiscal years.
 
    The  second part of the tax hike took effect on January 1, 1991, in the form
of an increased state income  tax on individuals. At  the time of enactment,  it
was  projected  that this  increase would  raise  approximately $1.3  billion in
additional income taxes to fund a new school aid formula, a new homestead rebate
program and state assumption of  welfare and social services costs.  Projections
and  estimates of receipts from income taxes, however, have also been subject to
variance in  recent  fiscal  years.  Under the  legislation,  income  tax  rates
increased  from their previous range of  2% to 3.5% to a  new range of 2% to 7%,
with the higher rates applying to married couples with incomes exceeding $70,000
who file joint returns, and to individuals filing single returns with incomes of
more than $35,000.
 
                                       45
<PAGE>
    The Florio administration  has contended  that the income  tax package  will
help  reduce  local  property  tax  increases by  providing  more  state  aid to
municipalities.  Under  the  income  tax  legislation  the  State  will   assume
approximately $289 million in social services costs that previously were paid by
counties and municipalities and funded by property taxes. In addition, under the
new formula for funding school aid, an extra $1.1 billion is proposed to be sent
by  the State to school districts beginning  in 1991, thus reducing the need for
property tax increases to support education programs.
 
    Effective July 1, 1992, the State's sales and use tax rate decreased from 7%
to 6%.
 
    On June 29, 1993 Governor Florio  signed the New Jersey Legislature's  $15.9
billion  budget for Fiscal Year  1994. The balanced budget  does not rely on any
new taxes,  college tuition  increases  or any  commuter fare  increases,  while
providing  a surplus of more than $400  million. Whether the State can achieve a
balanced budget  depends  on its  ability  to enact  and  implement  expenditure
reductions and to collect estimated tax revenues.
 
    LITIGATION. The State is a party in numerous legal proceedings pertaining to
matters  incidental to the performance  of routine governmental operations. Such
litigation includes, but is  not limited to, claims  asserted against the  State
arising   from  alleged  torts,  alleged  breaches  of  contracts,  condemnation
proceedings and other alleged violations of State and Federal laws. Included  in
the  State's  outstanding litigation  are cases  challenging the  following: the
formula relating to State aid to public  schools, the method by which the  State
shares with its counties maintenance recoveries and costs for residents in State
institutions,  unreasonably low Medicaid payment  rates for long-term facilities
in New  Jersey, the  obligation of  counties to  maintain Medicaid  or  Medicare
eligible  residents  of  institutions  and  facilities  for  the developmentally
disabled, taxes paid  into the Spill  Compensation Fund (a  fund established  to
provide  money for use  by the State  to remediate hazardous  waste sites and to
compensate other persons  for damages incurred  as a result  of hazardous  waste
discharge)   based   on  Federal   preemption,   various  provisions,   and  the
constitutionality, of  the Fair  Automobile Insurance  Reform Act  of 1990,  the
State's  method  of  funding  the judicial  system,  certain  provisions  of New
Jersey's hospital rate-setting  system, the adequacy  of Medicaid  reimbursement
for services rendered by doctors and dentists to Medicaid eligible children, the
Commissioner  of Health's calculation of the hospital assessment required by the
Health Care Cost  Reduction Act  of 1991,  refusal of  the State  to share  with
Camden  County federal funding the  State recently received for disproportionate
share hospital  payments made  to county  psychiatric facilities,  and  recently
enacted  legislation  calling for  a revaluation  of  several New  Jersey public
employee pension funds in order to  provide additional revenues for the  State's
general  fund.  Adverse judgments  in  these and  other  matters could  have the
potential  for  either  a   significant  loss  of   revenue  or  a   significant
unanticipated expenditure by the State.
 
    At  any given time,  there are various  numbers of claims  and cases pending
against the State,  State agencies  and employees seeking  recovery of  monetary
damages  that are  primarily paid out  of the  fund created pursuant  to the New
Jersey Tort  Claims Act.  In addition,  at  any given  time, there  are  various
numbers of contract claims against the State and State agencies seeking recovery
of  monetary damages.  The State  is unable to  estimate its  exposure for these
claims.
 
    DEBT RATINGS. For many years prior to 1991, both Moody's Investors  Service,
Inc. and Standard and Poor's Corporation had rated New Jersey general obligation
bonds Aaa and "AAA," respectively. On July 3, 1991, however, Standard and Poor's
Corporation  downgraded New Jersey general obligation bonds to "AA+." On June 4,
1992, Standard and Poor's
 
                                       46
<PAGE>
Corporation placed  New  Jersey general  obligation  bonds on  CreditWatch  with
negative  implications,  citing  as its  principal  reason for  its  caution the
unexpected denial by  the Federal Government  of New Jersey's  request for  $450
million  in retroactive Medicaid payments for psychiatric hospitals. These funds
were critical to closing a $1 billion gap in the State's $15 billion budget  for
fiscal  year 1992 which ended on June 30,  1992. Under New Jersey state law, the
gap in the current budget  must be closed before the  new budget year begins  on
July  1, 1992. Standard  and Poor's Corporation suggested  the State could close
fiscal 1992's budget gap and help fill fiscal 1993's hole by a reversion of $700
million of pension contributions to its general fund under a proposal to  change
the  way the State calculates  its pension liability. On  July 6, 1992, Standard
and Poor's  Corporation  reaffirmed its  "AA+"  rating for  New  Jersey  general
obligation  bonds and removed the  debt from its Credit  Watch list, although it
stated that New Jersey's long-term financial outlook was negative. Standard  and
Poor's  Corporation was  concerned that the  State was entering  the 1993 fiscal
year that began  July 1,  1992, with  a slim  $26 million  surplus and  remained
concerned  about whether the sagging State  economy would recover quickly enough
to meet lawmakers'  revenue projections.  It also remained  concerned about  the
recent federal ruling leaving in doubt how much the State was due in retroactive
Medicaid  reimbursements and a ruling by a  federal judge, now on appeal, of the
State's method for paying for uninsured hospital patients.
 
    On August 24, 1992,  Moody's Investors Service,  Inc. downgraded New  Jersey
general  obligation  bonds  to "Aa1",  stating  that the  reduction  reflected a
developing pattern of  reliance on  nonrecurring measures  to achieve  budgetary
balance,  four years  of financial operations  marked by  revenue shortfalls and
operating deficits, and  the likelihood that  serious financial pressures  would
persist.
 
    Although New Jersey recently received $412 million in settlement of its $450
million   dispute  with   the  federal   government  for   retroactive  medicaid
reimbursements, neither Moody's Investors Service, Inc. nor Standard and  Poor's
Corporation has revised its rating for New Jersey general obligation bonds.
 
NEW JERSEY TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The  following tables show the approximate taxable estimated current returns
for individuals  that are  equivalent to  tax-exempt estimated  current  returns
under  combined Federal and  state taxes, using  published 1994 marginal Federal
tax rates and marginal state tax  rates currently available and scheduled to  be
in  effect.  The  tables  incorporate  increased  tax  rates  for  higher-income
taxpayers that were  included in  the Revenue  Reconciliation Act  of 1993.  For
cases  in which more than one state  bracket falls within a Federal bracket, the
highest state bracket is combined with  the Federal bracket. The combined  state
and  Federal tax  brackets shown  reflect the fact  that state  tax payments are
currently deductible for Federal  tax purposes. The  tables illustrate what  you
would  have to  earn on  taxable investments  to equal  the tax-exempt estimated
current return for your  income tax bracket. A  taxpayer's marginal tax rate  is
affected  by both his taxable income and  his adjusted gross income. Locate your
adjusted gross and  your taxable  income (which  is your  adjusted gross  income
reduced by any deductions and exemptions), then locate your tax bracket based on
joint  or single  tax filing.  Read across  to the  equivalent taxable estimated
current return you would need to match the tax-free income.

      1 The table reflects the effect of the limitations  on itemized deductions and the deduction for personal exemptions.  They
were  designed to phase out certain benefits of these deductions for higher income taxpayers. These limitations, in effect, raise
the current maximum marginal Federal tax rate to approximately 44.0  percent for taxpayers filing a joint return and entitled  to
four  personal exemptions and to  approximately 41.0 percent for taxpayers  filing a single return  entitled to only one personal
exemption. These limitations are  subject to certain maximums,  which depend on  the number of exemptions  claimed and the  total
amount  of the taxpayer's itemized  deductions. For example, the limitation  on itemized deductions will  not cause a taxpayer to
lose more than 80% of his allowable itemized deductions, with certain exceptions.
      2 Federal tax rate reverts to 36.0% after the 80% cap on the limitation on itemized deductions has been met.
      3 Federal tax rate reverts to 39.6% after the 80% cap on the limitation on itemized deductions has been met.

the Trust and returns over specified periods on other similar Nuveen Trusts with
returns on taxable investments such as corporate or U.S. Government bonds,  bank
CD's  and  money  market accounts  or  money  market funds,  each  of  which has

Government  bonds, for example, are  backed by the full  faith and credit of the
U.S. Government and bank CD's and money market accounts are insured by an agency
of the federal government. Money market accounts and money market funds  provide
stability  of principal, but pay interest at  rates that vary with the condition
of the short-term debt market. The  investment characteristics of the Trust  are
described more fully elsewhere in this Prospectus.

PENNSYLVANIA INSURED TRUST 175
    
 
   
    The  Portfolio of Pennsylvania  Insured Trust 175  consists of 7 obligations
issued by  entities located  in Pennsylvania  and one  obligation issued  by  an
entity  located in the  Territory of Puerto  Rico. Three Bonds  in the Trust are
general obligations of the governmental entities issuing them and are backed  by
the  taxing powers thereof. Five Bonds in  the Trust are payable as to principal
and interest from  the income of  a specific  project or authority  and are  not
supported  by the issuer's power to levy taxes. The sources of payment for these
bonds are divided  as follows:  Dedicated-Tax Supported Revenue,  1; Bridge  and
Toll Road Revenue, 1; College and University Revenue, 1; Transportation Facility
Revenue,  1; Water and/or  Sewer Revenue, 1. All  of the Bonds  in the Trust, as
insured, are  rated AAA  by Standard  & Poor's  Corporation and  Aaa by  Moody's
Investors Service, Inc.
    
 
   
    At  the  Date  of  Deposit,  the  average  maturity  of  the  Bonds  in  the
Pennsylvania Insured Trust is 24.1 years. The average maturity of the Bonds in a
Trust is calculated based upon the stated maturities of the Bonds in such  Trust
(or,  with respect to  Bonds for which  funds or securities  have been placed in
escrow to redeem such Bonds on a  stated call date, based upon such call  date).
The  average maturity of the Bonds in a Trust may increase or decrease from time
to time as Bonds mature or are called or sold.
    
 
   
    Approximately 45.7% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 44.2% of the aggregate offering price of the
Bonds)  are original issue discount obligations. Certain of these original issue
discount obligations, amounting to  2.9% of the  aggregate principal amount  and
.9% of the aggregate offering price of the Bonds in the Trust, are "zero coupon"
bonds.  See  "GENERAL  TRUST  INFORMATION--ORIGINAL  ISSUE  DISCOUNT  BONDS  AND
STRIPPED  OBLIGATIONS"  for  a  discussion   of  the  characteristics  of   such
obligations and of the risks associated therewith.
    
 
    For  a discussion of the  risks associated with investments  in the bonds of
various issuers, see "General Trust Information" in this section.
 
   
    The Sponsor entered into contracts to acquire the Bonds between December 30,
1993 and January 4, 1994. The following summarizes certain information about the
Bonds as of the business day prior to the Date of Deposit:

</TABLE>
 
    Neither  cost  to  Sponsor  nor   profit  (or  loss)  to  Sponsor   reflects
underwriting  profits or losses received or  incurred by the Sponsor through its
participation  in  underwriting  syndicates.  An  underwriter  or   underwriting
syndicate  purchases bonds  from the issuer  on a negotiated  or competitive bid
basis as principal with  the motive of  marketing such bonds  to investors at  a
profit.  The Sponsor did not participate as  either the sole underwriter or as a
manager or member of a syndicate that  acted as the original underwriter of  any
of the Bonds.
 
   
    Unitholders  may elect  to have  interest distributions  made on  a monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the Pennsylvania Insured Trust, less estimated expenses, is estimated to  accrue
at  the  rate  of  $.01412  per  Unit per  day  under  the  semi-annual  plan of
distribution, $.01407 per Unit per day under the quarterly plan of  distribution
and    $.01398    per   Unit    per   day    under    the   monthly    plan   of
    
 
                                       50

distribution. It is anticipated  that the amount of  interest to be  distributed
per  Unit  in  each year  under  each  plan of  distribution  will  initially be
substantially equal to  the Estimated Net  Annual Interest Income  per Unit  for
that plan.
 
    Details of interest distributions per Unit of the Pennsylvania Insured Trust
under  the various plans appear in the  following table based upon estimated Net
Annual Interest Income at the Date of Deposit:

TAX STATUS--PENNSYLVANIA INSURED TRUST
 
    For  a discussion of the Federal tax status of income earned on Pennsylvania
Insured Trust Units, see Section 11.
 
    In the opinion of  Dechert Price & Rhoads,  special Pennsylvania counsel  to
the Series, under existing law:
 
        Units  evidencing  fractional  undivided interests  in  the Pennsylvania
    Insured Trust  are  not  subject  to any  of  the  personal  property  taxes
    presently  in effect in Pennsylvania to the extent of that proportion of the
    Trust represented by Bonds issued  by the Commonwealth of Pennsylvania,  its
    agencies  and  instrumentalities, or  by  any county,  city,  borough, town,
    township,  school  district,  municipality  and  local  housing  or  parking
    authority  in the Commonwealth of Pennsylvania or issued by Puerto Rico, the
    Virgin Islands, Guam or the Northern Mariana Islands ("Pennsylvania Bonds").
    The taxes referred to  above include the County  Personal Property Tax,  the
    additional  personal property taxes  imposed on Pittsburgh  residents by the
    School District of Pittsburgh  and by the  City of Pittsburgh.  Pennsylvania
    Insured  Trust Units may  be taxable under  the Pennsylvania inheritance and
    estate taxes.
 
        The proportion  of interest  income  representing interest  income  from
    Pennsylvania  Bonds distributed  to Unitholders of  the Pennsylvania Insured
    Trust is not taxable under the Pennsylvania Personal Income Tax or under the
    Corporate Net Income Tax  imposed on corporations by  Article IV of the  Tax
    Reform Code. Nor will such interest be taxable under the Philadelphia School
    District Investment Income Tax imposed on Philadelphia resident individuals.
 
        The disposition by the Pennsylvania Insured Trust of a Pennsylvania Bond
    (whether  by sale,  exchange, redemption  or payment  at maturity)  will not
    constitute a taxable
 
                                       51
<PAGE>
   
    event to a  Unitholder under  the Pennsylvania  Personal Income  Tax if  the
    Pennsylvania  Bond was issued  prior to February  1, 1994. Further, although
    there is no published  authority on the subject,  counsel is of the  opinion
    that  (i) a  Unitholder of  the Pennsylvania Insured  Trust will  not have a
    taxable event under the Pennsylvania  state and local income taxes  referred
    to in the preceding paragraph (other than the Corporate Net Income Tax) upon
    the  redemption or  sale of  his Unit  to the  extent that  the Pennsylvania
    Insured Trust  is  then comprised  of  Pennsylvania Bonds  issued  prior  to
    February 1, 1994 and (ii) the dispositions by the Pennsylvania Insured Trust
    of  a Pennsylvania Bond (whether by sale, exchange, redemption or payment at
    maturity) will not  constitute a  taxable event  to a  Unitholder under  the
    Corporate  Net  Income Tax  or the  Philadelphia School  District Investment
    Income Tax if the  Pennsylvania Bond was issued  prior to February 1,  1994.
    (The  School District tax has  no application to gain  on the disposition of
    property held by the taxpayer for more than six months.)
    
 
   
        Gains on the  sale, exchange, redemption,  or payment at  maturity of  a
    Pennsylvania Bond issued on or after February 1, 1994, will be taxable under
    all of these taxes, as will gains on the redemption or sale of a unit to the
    extent  that the Trust is comprised of Pennsylvania Bonds issued on or after
    February 1, 1994.
    
 
ECONOMIC FACTORS--PENNSYLVANIA
 
    RISK  FACTORS--Prospective   investors   should   consider   the   financial
difficulties and pressures which the Commonwealth of Pennsylvania and certain of
its municipal subdivisions have undergone. Both the Commonwealth and the City of
Philadelphia  are experiencing significant  revenue shortfalls. There  can be no
assurance that  the  Commonwealth  will  not experience  a  further  decline  in
economic  conditions or that portions of  the municipal obligations purchased by
the Fund  will not  be  affected by  such a  decline.  Without intending  to  be
complete,  the following briefly  summarizes some of  these difficulties and the
current financial situation, as  well as some of  the complex factors  affecting
the financial situation in the Commonwealth. It is derived from sources that are
generally  available to investors  and is based in  part on information obtained
from various agencies in the Commonwealth. No independent verification has  been
made of the following information.
 
    STATE  ECONOMY--Pennsylvania  has been  historically  identified as  a heavy
industry state although that reputation  has changed recently as the  industrial
composition  of the Commonwealth  diversified when the  coal, steel and railroad
industries began to decline. The major new sources of growth in the Commonwealth
are in  the  service  sector,  including trade,  medical  and  health  services,
education and financial institutions. The Commonwealth's agricultural industries
are  also an important component of  its economic structure, accounting for more
than $3.6 billion in crop and livestock products annually while agribusiness and
food related industries support $38 billion in economic activity annually.
 
    Non-agricultural employment within the  Commonwealth has increased  steadily
from  1984 to its 1992 level of 81.3  percent of total employment. The growth in
employment experienced  in  the Commonwealth  is  comparable to  the  nationwide
growth   in  employment  which  has  occurred   during  this  period.  In  1992,
manufacturing  employment  represented  18.7  percent  of  all  non-agricultural
employment  in the  Commonwealth while  the services  sector accounted  for 29.3
percent and the trade sector accounted for 22.7 percent.
 
    The Commonwealth is currently  facing a slowdown  in its economy.  Moreover,
economic  strengths and weaknesses vary in  different parts of the Commonwealth.
In general, heavy
 
                                       52
<PAGE>
   
industry and manufacturing have been facing increasing competition from  foreign
producers. During 1992, the annual average unemployment rate in the Commonwealth
was 7.5 percent compared to 7.4 percent for the United States. For November 1993
the  unadjusted unemployment  rate was 6.7  percent in the  Commonwealth and 6.1
percent in the United  States, while the  seasonally adjusted unemployment  rate
for the Commonwealth was 7.2 percent and for the United States was 6.4 percent.
    
    STATE  BUDGET--The  Commonwealth operates  under an  annual budget  which is
formulated and submitted for legislative approval by the Governor each February.
The Pennsylvania  Constitution  requires  that the  Governor's  budget  proposal
consist  of three parts: (i) a  balanced operating budget setting forth proposed
expenditures and estimated revenues from all sources and, if estimated  revenues
and available surplus are less than proposed expenditures, recommending specific
additional  sources of revenue sufficient to  pay the deficiency; (ii) a capital
budget setting forth proposed expenditures to  be financed from the proceeds  of
obligations  of the  Commonwealth or its  agencies or from  operating funds; and
(iii) a financial plan for not less than the succeeding five fiscal years, which
includes for each year projected  operating expenditures and estimated  revenues
and  projected expenditures for capital projects.  The General Assembly may add,
change or delete  any items  in the  budget prepared  by the  Governor, but  the
Governor  retains veto  power over the  individual appropriations  passed by the
legislature. The Commonwealth's fiscal  year begins on July  1 and ends on  June
30.
 
    All  funds  received by  the Commonwealth  are  subject to  appropriation in
specific amounts by the  General Assembly or by  executive authorization by  the
Governor.  Total appropriations enacted  by the General  Assembly may not exceed
the ensuing  year's  estimated revenues,  plus  (less) the  unappropriated  fund
balance  (deficit) of the preceding year, except for constitutionally authorized
debt service payments. Appropriations from the principal operating funds of  the
Commonwealth  (the General  Fund, the Motor  License Fund and  the State Lottery
Fund)  are  generally  made  for  one  fiscal  year  and  are  returned  to  the
unappropriated  surplus of the fund if not spent or encumbered by the end of the
fiscal year. The Constitution specifies that a surplus of operating funds at the
end of a fiscal year must be appropriated for the ensuing year.
 
    Pennsylvania  uses  the  "fund"  method  of  accounting  for  receipts   and
disbursements. For purposes of government accounting, a "fund" is an independent
fiscal  and accounting entity  with a self-balancing  set of accounts, recording
cash and/or other resources together with all related liabilities and  equities.
In  the  Commonwealth,  over  120 funds  have  been  established  by legislative
enactment or  in certain  cases  by administrative  action  for the  purpose  of
recording  the receipts and disbursement of moneys received by the Commonwealth.
Annual budgets are adopted each fiscal year for the principal operating funds of
the Commonwealth  and  several other  special  revenue funds.  Expenditures  and
encumbrances  against these  funds may  only be  made pursuant  to appropriation
measures enacted  by the  General Assembly  and approved  by the  Governor.  The
General  Fund,  the  Commonwealth's  largest fund,  receives  all  tax revenues,
non-tax revenues and federal grants and  entitlements that are not specified  by
law  to be deposited elsewhere. The majority of the Commonwealth's operating and
administrative expenses are payable from the  General Fund. Debt service on  all
bond  indebtedness of the Commonwealth, except  that issued for highway purposes
or for the benefit of other special  revenue funds, is payable from the  General
Fund.
 
    Financial  information for the principal operating funds of the Commonwealth
are maintained on a budgetary basis of accounting, which is used for the purpose
of insuring compliance with the enacted operating budget. The Commonwealth  also
prepares annual financial
 
                                       53
<PAGE>
statements in accordance with generally accepted accounting principles ("GAAP").
Budgetary  basis  financial  reports  are  based on  a  modified  cash  basis of
accounting as opposed to  a modified accrual basis  of accounting prescribed  by
GAAP.   Financial  information  is  adjusted   at  fiscal  year-end  to  reflect
appropriate accruals for financial reporting in conformity with GAAP.
 
    RECENT FINANCIAL RESULTS--At  the end of  fiscal 1990 and  fiscal 1991,  the
unreserved  -undesignated  fund  balance was  a  negative $205.8  million  and a
negative $1,189.2 million,  respectively, a  drop of $579.6  million and  $983.4
million,  respectively, from the year-earlier amounts. The decline in the fiscal
1990 unreserved-undesignated fund balance for government fund types was  largely
the  result of  a $718.2  million operating  deficit in  the General  Fund which
caused the total fund balance of the  General Fund to fall to a negative  $119.8
million at June 30, 1990. The decline in the fiscal 1991 unreserved-undesignated
fund  balance  was  principally the  result  of operating  deficits  of $1,076.6
million and  $66.2 million,  respectively, in  the General  Fund and  the  State
Lottery Fund.
 
    Rising   demands  on  state  programs  caused  by  the  economic  recession,
particularly for  medical  assistance  and cash  assistance  programs,  and  the
increased  costs  of special  education programs  and correction  facilities and
programs, contributed  to  increased  expenditures in  fiscal  1991,  while  tax
revenues  for  the  1991 fiscal  year  were  severely affected  by  the economic
recession. Total corporation tax receipts and sales and use tax receipts  during
fiscal  1991  were,  respectively, 7.3  percent  and 0.9  percent  below amounts
collected during fiscal 1990. Personal income tax receipts also were affected by
the recession but  not to  the extent  of the  other major  General Fund  taxes,
increasing only 2.0 percent over fiscal 1990 collections.
 
    The  Commonwealth experienced a $454 million  general fund deficit as of the
end of  its 1991  fiscal  year. The  deficit reflected  below-estimate  economic
activity  and  growth  rates  of  economic  indicators  and  total  tax  revenue
shortfalls of $817  million (4.1  percent) below  those assumed  in the  enacted
budget.  Economic conditions  also affected  expenditure trends  during the 1991
fiscal year,  with expenditures  for medical  assistance costs  and other  human
service  programs  running  $512 million  above  estimates assumed  in  the 1991
budget. In  January 1991,  the Commonwealth  initiated a  number of  cost-saving
measures,  including the firing of 2,000  state employees, deferral of paychecks
and reduction of funds  to state universities,  which resulted in  approximately
$871 million cost savings.
 
    Total general fund revenues for fiscal 1992 were $14,516.8 million, which is
approximately  22 percent higher than fiscal  1991 revenues of $11,877.3 million
due in large part  to tax increases. The  increased revenues funded  substantial
increases in education, social services and corrections programs. As a result of
the  tax increases and  certain appropriation lapses, fiscal  1992 ended with an
$8.8 million  surplus  after having  started  the year  with  an  unappropriated
balance deficit of $453.6 million.
 
    FISCAL   1993  BUDGET.--On  June  30,  1992,  the  Pennsylvania  legislature
presented the Governor with a $14.126  billion general fund budget for the  1993
fiscal  year,  which began  on  July 1,  1992.  Before signing  the  budget, the
Governor deleted approximately $73 million in certain state expenditures such as
aid to county courts and district justices. As a result, the budget for the 1993
fiscal year  was  approximately $14.046  billion,  which is  approximately  $105
million  more than  the fiscal  1992 budget. On  February 9,  1993, the Governor
announced that he anticipated that  the 1993 budget would  be in balance at  the
end of the fiscal year.

<PAGE>
    FISCAL  1994 BUDGET--On  May 28, 1993,  the Governor signed  a $14.9 billion
general fund budget, an increase of  approximately five percent from the  fiscal
1993  budget.  A substantial  amount  of the  increase  is targeted  for medical
assistance programs and prisons.
 
    DEBT LIMITS AND OUTSTANDING DEBT--The Pennsylvania Constitution permits  the
issuance  of the following types  of debt: (i) debt  to suppress insurrection or
rehabilitate areas affected  by disaster; (ii)  electorate approved debt;  (iii)
debt for capital projects subject to an aggregate outstanding debt limit of 1.75
times  the annual average tax  revenues of the preceding  five fiscal years; and
(iv) tax anticipation notes payable in the fiscal year of issuance.
 
    Under the Pennsylvania Fiscal Code, the Auditor General is required annually
to certify  to  the  Governor  and  the  General  Assembly  certain  information
regarding  the Commonwealth's indebtedness. According to the most recent Auditor
General certificate, the average annual tax  revenues deposited in all funds  in
the  five fiscal years ended June 30, 1993 was $14.5 billion, and therefore, the
net debt limitation for the 1994  fiscal year is $27.1 billion. Outstanding  net
debt  totaled $4.0 billion  at June 30,  1993, a decrease  of $42.2 million from
June 30, 1992. At September 1, 1993, the amount of debt authorized by law to  be
issued, but not yet incurred was $15.1 billion.
 
    DEBT  RATINGS--All outstanding general obligation  bonds of the Commonwealth
are rated AA- by S&P and A1 by Moody's.
 
    CITY OF  PHILADELPHIA--The  City of  Philadelphia  experienced a  series  of
general  fund deficits for fiscal years  1988 through 1992 which have culminated
in the City's present serious financial difficulties. In its 1992  Comprehensive
Annual Financial Report, Philadelphia reported a cumulative general fund deficit
of $71.4 million for fiscal year 1992.
 
    In  June  1991, the  Pennsylvania  legislature established  the Pennsylvania
Intergovernmental Cooperation Authority ("PICA"), a five-member board which will
oversee the fiscal affairs of the City of Philadelphia. The Legislation empowers
PICA to issue  notes and bonds  on behalf of  Philadelphia, and also  authorizes
Philadelphia to levy a one-percent sales tax the proceeds of which would be used
to  pay off the bonds. In return  for PICA's fiscal assistance, Philadelphia was
required, among  other things,  to  establish a  five-year financial  plan  that
includes  balanced annual budgets.  Under the legislation,  if Philadelphia does
not comply, PICA may withhold bond revenues and certain state funding.
 
   
    In May 1992, the city counsel of Philadelphia approved the Mayor's five-year
plan and adopted a fiscal 1993 budget. On June 5, 1992, PICA sold  approximately
$480  million in bonds at yields ranging  from 5.25 percent to 6.88 percent. The
proceeds of the bonds will be used to cover shortfalls accumulated over the last
four fiscal years, projected deficits for fiscal year 1992 and fiscal year 1993,
construction projects and  other capital  expenditures. In  accordance with  the
enabling  legislation, PICA  has been  guaranteed a  percentage of  the wage tax
revenue expected to be collected from Philadelphia residents to permit repayment
of the bonds. In connection  with PICA's issuance of  the bonds, S&P raised  the
rating  on Philadelphia's  general obligation bonds  to "BB."  Moody's rating is
currently "Ba."
    
    In January 1993, Philadelphia anticipated  a cumulative general fund  budget
deficit  of $57 million for the 1993 fiscal year. In response to the anticipated
deficit, the Mayor unveiled a financial plan eliminating the budget deficit  for
the  1993 budget year through  significant service cuts that  included a plan to
privatize certain city provided  services. Philadelphia currently anticipates  a
balanced  general fund budget for the 1993 fiscal  year due to an upsurge in tax
receipts,  cost-cutting  and  privatization   of  city  provided  services   and
additional PICA borrowings.

    LITIGATION--The  Commonwealth is  a party to  numerous lawsuits  in which an
adverse final decision could  materially affect the Commonwealth's  governmental
operations  and consequently its ability to pay debt service on its obligations.
The Commonwealth also faces tort claims  made possible by the limited waiver  of
sovereign immunity effected by Act 152, approved September 28, 1978.
 
PENNSYLVANIA TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The  following tables show the approximate taxable estimated current returns
for individuals  that are  equivalent to  tax-exempt estimated  current  returns
under  combined Federal and  state taxes, using  published 1994 marginal Federal
tax rates and marginal state tax  rates currently available and scheduled to  be
in  effect.  The  tables  incorporate  increased  tax  rates  for  higher-income
taxpayers that were  included in  the Revenue  Reconciliation Act  of 1993.  For
cases  in which more than one state  bracket falls within a Federal bracket, the
highest state bracket is combined with  the Federal bracket. The combined  state
and  Federal tax  brackets shown  reflect the fact  that state  tax payments are
currently deductible for Federal  tax purposes. The  tables illustrate what  you
would  have to  earn on  taxable investments  to equal  the tax-exempt estimated
current return for your  income tax bracket. A  taxpayer's marginal tax rate  is
affected  by both his taxable income and  his adjusted gross income. Locate your
adjusted gross and  your taxable  income (which  is your  adjusted gross  income
reduced by any deductions and exemptions), then locate your tax bracket based on
joint  or single  tax filing.  Read across  to the  equivalent taxable estimated
current return you would need to match the tax-free income.

      1 The table reflects the effect of the limitations  on itemized deductions and the deduction for personal exemptions.  They
were  designed to phase out certain benefits of these deductions for higher income taxpayers. These limitations, in effect, raise
the current maximum marginal Federal tax rate to approximately 44.0  percent for taxpayers filing a joint return and entitled  to
four  personal exemptions and to  approximately 41.0 percent for taxpayers  filing a single return  entitled to only one personal
exemption. These limitations are  subject to certain maximums,  which depend on  the number of exemptions  claimed and the  total
amount  of the taxpayer's itemized  deductions. For example, the limitation  on itemized deductions will  not cause a taxpayer to
lose more than 80% of his allowable itemized deductions, with certain exceptions.
      2 Federal tax rate reverts to 36.0% after the 80% cap on the limitation on itemized deductions has been met.
      3 Federal tax rate reverts to 39.6% after the 80% cap on the limitation on itemized deductions has been met.

    A comparison of  tax-free and equivalent  taxable estimated current  returns
with  the returns on various  taxable investments is one  element to consider in
making an  investment  decision.  The Sponsor  may  from  time to  time  in  its
advertising  and sales materials  compare the then  current estimated returns on
the Trust and returns over specified periods on other similar Nuveen Trusts with
returns on taxable investments such as corporate or U.S. Government bonds,  bank
CD's  and  money  market accounts  or  money  market funds,  each  of  which has
investment characteristics  that  may  differ  from those  of  the  Trust.  U.S.
Government  bonds, for example, are  backed by the full  faith and credit of the
U.S. Government and bank CD's and money market accounts are insured by an agency
of the federal government. Money market accounts and money market funds  provide
stability  of principal, but pay interest at  rates that vary with the condition
of the short-term debt market. The  investment characteristics of the Trust  are
described more fully elsewhere in this Prospectus.

* These  Bonds,  or a  portion thereof,  have delivery  dates beyond  the normal
  settlement date. Their expected delivery  date is January 18, 1994.  Contracts
  relating  to  Bonds  with delivery  dates  after  the date  of  settlement for
  purchase made  on the  Date of  Deposit constitute  approximately 11%  of  the
  aggregate principal amount of the Trust. (See Section 4.)

NOTES TO SCHEDULES OF INVESTMENTS
 
    (1) Contracts,  which  are  "when-issued"  or  "regular  way"  contracts  or
        contracts having delivery dates beyond the normal settlement date,  have
        been  deposited with the Trustee on the Date of Deposit. The performance
        of such contracts is secured by an irrevocable letter of credit,  issued
        by  a major commercial bank, which  has been deposited with the Trustee.
        At the Date  of Deposit, Bonds  may have been  delivered to the  Sponsor
        pursuant  to certain of these contracts; the Sponsor has assigned to the
        Trustee all of its right, title and interest in and to such Bonds.
 
    (2) The Bonds are first subject to optional redemption in the years, and  at
        the  prices, shown.  Unless otherwise  indicated, the  Bonds, except for
        Bonds issued at a substantial original issue discount, are redeemable at
        declining prices (but not below par value) in subsequent years. Original
        issue  discount  bonds,  including  zero  coupon  bonds,  are  generally
        redeemable  at  prices  based on  the  issue  price plus  the  amount of
        original issue discount accreted to redemption plus, if applicable, some
        premium, the amount of which will decline in subsequent years. The Bonds
        may also be subject to sinking fund redemption without premium prior  to
        the dates shown.
 
        Certain  Bonds may be subject to redemption without premium prior to the
        date shown  pursuant  to  special  or  mandatory  call  provisions;  for
        example,  if bond proceeds are not able  to be used as contemplated, the
        project is condemned or sold, or the project is destroyed and  insurance
        proceeds  are used to  redeem the bonds.  Single family mortgage revenue
        bonds and housing authority bonds are  most likely to be called  subject
        to  such provisions, but other bonds may have similar call features. See
        Section 4 and "General Trust Information" in this Section.
 
        The Trustee's determination of the offering prices of Bonds in the  Fund
        may  be  greater or  less than  the  amounts that  may be  received upon
        redemption or  maturity  of  such Bonds.  Subject  to  rules  concerning
        amortization  of bond  premium and of  original issue  discount, gain or
        loss realized  by  the Trustee  on  disposition  of any  Bonds  will  be
        recognized  as taxable capital gain or loss by Unitholders. (See Section
        4.)
 
    (3) See "Description  of  Ratings" herein.  All  the Bonds  in  the  Insured
        Trusts,  as insured by the  Insurer, are rated AAA  by Standard & Poor's
        Corporation and Aaa by Moody's Investors Service, Inc. (See Section 5.)
 
    (4) As determined by Kenny S&P Evaluation Services on behalf of the  Trustee
        as  of the close of  business on the business  day preceding the Date of
        Deposit. The prices as determined by Kenny S&P Evaluation Services  have
        been rounded to the nearest dollar.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
   
     TO  THE  BOARD OF  DIRECTORS  OF JOHN  NUVEEN  & CO.  INCORPORATED AND
     UNITHOLDERS OF NUVEEN TAX-EXEMPT UNIT TRUST, SERIES 711:
    
 
   
       We have audited  the accompanying  statements of  condition and  the
     related  schedules of investments at date  of deposit (included in the
     prospectus  herein)  of  Nuveen  Tax-Exempt  Unit  Trust,  Series  711
     (comprising  California Insured Trust 219,  Florida Insured Trust 184,
     Massachusetts Insured  Trust 109,  New Jersey  Insured Trust  171  and
     Pennsylvania  Insured  Trust  175),  as  of  January  6,  1994.  These
     financial statements  are  the  responsibility  of  the  Sponsor.  Our
     responsibility  is to express an opinion on these financial statements
     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  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 the irrevocable letter  of credit arrangement for  the
     purchase  of securities,  described in Note  (1) to  the statements of
     condition, by correspondence with the Trustee. An audit also  includes
     assessing  the  accounting principles  used and  significant estimates
     made by  the Sponsor,  as  well as  evaluating the  overall  financial
     statement   presentation.  We  believe  that   our  audits  provide  a
     reasonable basis for our opinion.
 
   
       In  our  opinion,  the  statements  of  condition  and  the  related
     schedules  of investments at date of deposit referred to above present
     fairly, in all material  respects, the financial  position of each  of
     the  trusts constituting the Nuveen  Tax-Exempt Unit Trust, Series 711
     as  of  January  6,  1994,  in  conformity  with  generally   accepted
     accounting principles.

    of the close of business on the business day prior to the Date of Deposit. (See Section 10.) Insurance coverage providing for
    the  timely payment, when due, of all principal  of and interest on the Bonds in  the Insured Trusts has been obtained by the
    Sponsor or by the issuers of such Bonds. Such insurance does not guarantee the market value of the Bonds or the value of  the

GENERAL TRUST INFORMATION
 
    An  investment in Units of any Trust should be made with an understanding of
the risks that  such an investment  may entail.  As set forth  in the  portfolio
summaries above, the Trusts may contain or be concentrated in one or more of the
types  of  bonds  discussed  below.  The  following  paragraphs  discuss certain
circumstances which may adversely affect the ability of issuers of Bonds held in
the portfolio of a Trust  to make payment of  principal and interest thereon  or
which  may adversely affect the  ratings of such Bonds;  with respect to Insured
Trusts, however, because  of the  insurance obtained by  the Sponsor  or by  the
issuers  of  the Bonds,  such  changes should  not  adversely affect  an Insured
Trust's receipt of principal and interest, the Standard & Poor's AAA or  Moody's
Aaa  ratings of  the Bonds  in the  Insured Trust  portfolio, or  the Standard &
Poor's AAA rating of the Units of each such Insured Trust.
 
    HEALTH FACILITY  OBLIGATIONS.    Some  of  the  Bonds  in  a  Trust  may  be
obligations  of issuers  whose revenues  are derived  from services  provided by
hospitals or other health care  facilities, including nursing homes. Ratings  of
bonds  issued  for health  care facilities  are  sometimes based  on feasibility
studies that contain projections of  occupancy levels, revenues and expenses.  A
facility's  gross  receipts and  net income  available for  debt service  may be
affected by future events and  conditions including, among other things,  demand
for  services, the ability of the facility  to provide the services required, an
increasing shortage of qualified nurses or a dramatic rise in nursing  salaries,
physicians'  confidence  in  the  facility,  management  capabilities,  economic
developments in  the service  area, competition  from other  similar  providers,
efforts  by  insurers  and  governmental agencies  to  limit  rates, legislation
establishing state rate-setting agencies,  expenses, government regulation,  the
cost  and possible unavailability of  malpractice insurance, and the termination
or restriction of governmental  financial assistance, including that  associated
with  Medicare, Medicaid and other similar  third party payor programs. Medicare
reimbursements are currently calculated on a prospective basis and are not based
on a provider's actual costs. Such method of reimbursement may adversely  affect
reimbursements to hospitals and other facilities for services provided under the
Medicare  program and thereby may have an  adverse effect on the ability of such
institutions to satisfy  debt service requirements.  In the event  of a  default
upon  a bond  secured by hospital  facilities, the limited  alternative uses for
such facilities may result  in the recovery upon  such collateral not  providing
sufficient funds to fully repay the bonds.
 
    Certain  hospital  bonds  provide for  redemption  at par  upon  the damage,
destruction or  condemnation of  the  hospital facilities  or in  other  special
circumstances.
 
    HOUSING  OBLIGATIONS.  Some  of the Bonds  in a Trust  may be obligations of
issuers whose  revenues are  primarily derived  from mortgage  loans to  housing
projects  for  low  to  moderate  income  families.  Such  issues  are generally
characterized by mandatory redemption at par  or, in the case of original  issue
discount  bonds, accreted  value in  the event of  economic defaults  and in the
event of a failure of the operator of a project to comply with certain covenants
as to the operation of the project. The failure of such operator to comply  with
certain  covenants related  to the tax-exempt  status of interest  on the Bonds,
such as provisions requiring that a  specified percentage of units be rented  or
available for rental to low or moderate income families, potentially could cause
interest on such Bonds to be subject to Federal income taxation from the date of
issuance of the Bonds. The ability of such issuers to make debt service payments
will   be  affected  by  events  and  conditions  affecting  financed  projects,
including, among other  things, the  achievement and  maintenance of  sufficient
occupancy  levels and adequate  rental income, employment  and income conditions
prevailing in local labor markets, increases  in taxes, utility costs and  other
operating  expenses, the managerial ability of project managers, changes in laws
and
 
                                      A-1
<PAGE>
governmental  regulations,  the  appropriation  of  subsidies,  and  social  and
economic  trends affecting  the localities  in which  the projects  are located.
Occupancy of such housing projects may be adversely affected by high rent levels
and income limitations imposed under Federal and state programs.
 
    SINGLE FAMILY MORTGAGE REVENUE BONDS.  Some  of the Bonds in a Trust may  be
single  family  mortgage revenue  bonds,  which are  issued  for the  purpose of
acquiring from originating financial institutions notes secured by mortgages  on
residences located within the issuer's boundaries and owned by persons of low or
moderate  income. Mortgage loans  are generally partially  or completely prepaid
prior to  their final  maturities as  a result  of events  such as  sale of  the
mortgaged  premises, default, condemnation or casualty loss. Because these bonds
are subject to extraordinary mandatory redemption in whole or in part from  such
prepayments of mortgage loans, a substantial portion of such bonds will probably
be  redeemed prior to their scheduled maturities or even prior to their ordinary
call dates. Extraordinary mandatory redemption without premium could also result
from the  failure of  the originating  financial institutions  to make  mortgage
loans in sufficient amounts within a specified time period. The redemption price
of  such issues  may be  more or  less than  the offering  price of  such bonds.
Additionally, unusually high rates of  default on the underlying mortgage  loans
may  reduce revenues available  for the payment  of principal of  or interest on
such mortgage revenue bonds. Single  family mortgage revenue bonds issued  after
December 31, 1980 were issued under Section 103A of the Internal Revenue Code of
1954,  as amended, or  Section 143 of  the Internal Revenue  Code of 1986, which
Sections contain certain  requirements relating to  the use of  the proceeds  of
such  bonds in  order for the  interest on  such bonds to  retain its tax-exempt
status. In each  case, the issuer  of the  bonds has covenanted  to comply  with
applicable  requirements and bond  counsel to such issuer  has issued an opinion
that the interest on the bonds is exempt from Federal income tax under  existing
laws   and  regulations.  There  can  be   no  assurance  that  such  continuing
requirements will  be satisfied;  the failure  to meet  such requirements  could
cause  interest on the Bonds to be  subject to Federal income taxation, possibly
from the date of issuance of the Bonds.
 
    FEDERALLY ENHANCED  OBLIGATIONS.   Some of  the mortgages  which secure  the
various  health care or housing projects which underlie the previously discussed
Health Facility, Housing,  and Single Family  Mortgage Revenue Obligations  (the
"Obligations")  in a Trust may be  insured by the Federal Housing Administration
("FHA"). Under FHA  regulations, the  maximum insurable  mortgage amount  cannot
exceed  90%  of the  FHA's  estimated value  of  the project.  The  FHA mortgage
insurance does not constitute a guarantee of timely payment of the principal  of
and  interest on the Obligations. Payment  of mortgage insurance benefits may be
(1) less than the principal amount of Obligations outstanding or (2) delayed  if
disputes  arise as to  the amount of the  payment or if  certain notices are not
given to the FHA within  the prescribed time periods.  In addition, some of  the
previously  discussed Obligations may be secured by mortgage-backed certificates
guaranteed by the  Government National Mortgage  Association ("GNMA"), a  wholly
owned  corporate  instrumentality  of  the  United  States,  and/or  the Federal
National  Mortgage  Association  ("Fannie   Mae")  a  federally  chartered   and
stockholder-owed  corporation. GNMA and  Fannie Mae guarantee  timely payment of
principal and  interest  on the  mortgage-backed  certificates, even  where  the
underlying   mortgage  payments   are  not  made.   While  such  mortgage-backed
certificates are often pledged  to secure payment of  principal and interest  on
the  Obligations, timely payment of interest and principal on the Obligations is
not insured or guaranteed by  the United States, GNMA,  Fannie Mae or any  other
governmental  agency or  instrumentality. The  GNMA mortgage-backed certificates
constitute a general obligation  of the United States  backed by its full  faith
and  credit. The obligations of Fannie  Mae, including its obligations under the
Fannie Mae mortgage-backed securities, are obligations
 
                                      A-2
<PAGE>
solely of Fannie Mae and are not backed  by, or entitled to, the full faith  and
credit of the United States.
 
    INDUSTRIAL  REVENUE OBLIGATIONS.   Certain  of the Bonds  in a  Trust may be
industrial revenue bonds  ("IRBs"), including pollution  control revenue  bonds,
which  are  tax-exempt  securities  issued  by  states,  municipalities,  public
authorities or similar entities to  finance the cost of acquiring,  constructing
or improving various industrial projects. These projects are usually operated by
corporate entities. Issuers are obligated only to pay amounts due on the IRBs to
the  extent that funds are available from the unexpended proceeds of the IRBs or
receipts or revenues of the issuer  under an arrangement between the issuer  and
the  corporate operator of  a project. The arrangement  may be in  the form of a
lease, installment sale agreement, conditional sale agreement or loan agreement,
but in each case  the payments to  the issuer are designed  to be sufficient  to
meet  the payments  of amounts  due on  the IRBs.  Regardless of  the structure,
payment of IRBs is solely dependent  upon the creditworthiness of the  corporate
operator  of  the project  and,  if applicable,  corporate  guarantor. Corporate
operators or  guarantors may  be affected  by  many factors  which may  have  an
adverse  impact on  the credit  quality of  the particular  company or industry.
These include cyclicality of revenues and earnings, regulatory and environmental
restrictions, litigation  resulting  from  accidents  or  environmentally-caused
illnesses,  extensive competition  and financial deterioration  resulting from a
corporate restructuring pursuant to a leveraged buy-out, takeover or  otherwise.
Such  a restructuring may  result in the  operator of a  project becoming highly
leveraged which may have an impact on such operator's creditworthiness which  in
turn  would have  an adverse impact  on the  rating and/or market  value of such
Bonds. Further, the  possibility of  such a  restructuring may  have an  adverse
impact  on the market for and consequently  the value of such Bonds, even though
no actual takeover or other action is ever contemplated or effected. The IRBs in
a Trust may be subject to  special or extraordinary redemption provisions  which
may  provide for redemption  at par or,  in the case  of original issue discount
bonds, accreted value. The  Sponsor cannot predict the  causes or likelihood  of
the redemption of IRBs in a Trust prior to the stated maturity of such Bonds.
 
    ELECTRIC  UTILITY  OBLIGATIONS.    Some  of the  Bonds  in  a  Trust  may be
obligations of issuers  whose revenues are  primarily derived from  the sale  of
electric  energy. The problems  faced by such issuers  include the difficulty in
obtaining approval for timely  and adequate rate  increases from the  applicable
public  utility  commissions,  the difficulty  of  financing  large construction
programs, increased competition,  reductions in estimates  of future demand  for
electricity  in certain areas of the  country, the limitations on operations and
increased costs  and delays  attributable to  environmental considerations,  the
difficulty  of the capital  market in absorbing utility  debt, the difficulty in
obtaining fuel at reasonable prices and  the effect of energy conservation.  All
of  such issuers  have been  experiencing certain  of these  problems in varying
degrees. In addition, Federal, state and municipal governmental authorities  may
from  time to time review existing, and impose additional, regulations governing
the licensing, construction  and operation  of nuclear power  plants, which  may
adversely  affect the ability of the issuers of  certain of the Bonds in a Trust
to make payments of principal and/or interest on such Bonds.
 
    TRANSPORTATION FACILITY REVENUE BONDS.  Some of the Bonds in a Trust may  be
obligations  of issuers which  are payable from and  secured by revenues derived
from the ownership and operation of airports, public transit systems and  ports.
The  major portion of  an airport's gross operating  income is generally derived
from fees received  from airlines pursuant  to use agreements  which consist  of
annual  payments for airport  use, occupancy of  certain terminal space, service
fees and  leases. Airport  operating income  may therefore  be affected  by  the
ability  of the airlines to meet their obligations under the use agreements. The
air transport industry  is experiencing significant  variations in earnings  and
 
                                      A-3
<PAGE>
traffic,  due  to  increased  competition,  excess  capacity,  increased  costs,
deregulation, traffic constraints  and other factors,  and several airlines  are
experiencing  severe financial difficulties. In  particular, facilities with use
agreements involving airlines experiencing financial difficulty may experience a
reduction in revenue  due to the  possible inability of  these airlines to  meet
their  use  agreement obligations  because  of such  financial  difficulties and
possible bankruptcy.  The  Sponsor cannot  predict  what effect  these  industry
conditions  may have on airport revenues which  are dependent for payment on the
financial condition of the  airlines and their usage  of the particular  airport
facility.  Bonds that are secured primarily by the revenue collected by a public
transit system  typically are  additionally secured  by a  pledge of  sales  tax
receipts  collected  at  the state  or  local  level, or  of  other governmental
financial assistance. Transit system net revenues will be affected by variations
in  utilization,  which  in  turn  may  be  affected  by  the  degree  of  local
governmental  subsidization, demographic and  population shifts, and competition
from other  forms of  transportation; and  by increased  costs, including  costs
resulting  from previous deferrals of maintenance. Port authorities derive their
revenues primarily from fees imposed on ships using the facilities. The rate  of
utilization  of such facilities may fluctuate depending on the local economy and
on competition from  competing forms  of transportation  such as  air, rail  and
trucks.
 
    WATER  AND/OR SEWERAGE  OBLIGATIONS.  Some  of the  Bonds in a  Trust may be
obligations of issuers whose revenues are derived from the sale of water  and/or
sewerage services. Such Bonds are generally payable from user fees. The problems
of  such  issuers  include  the  ability  to  obtain  timely  and  adequate rate
increases, population decline resulting in  decreased user fees, the  difficulty
of  financing  large construction  programs, the  limitations on  operations and
increased costs  and delays  attributable to  environmental considerations,  the
increasing  difficulty of obtaining or discovering  new supplies of fresh water,
the effect  of  conservation  programs  and the  impact  of  "no-growth"  zoning
ordinances. All of such issuers have been experiencing certain of these problems
in varying degrees.
 
    UNIVERSITY  AND COLLEGE REVENUE OBLIGATIONS.   Some of the  Bonds in a Trust
may be  obligations of  issuers which  are, or  which govern  the operation  of,
colleges  and universities and  whose revenues are  derived mainly from tuition,
dormitory revenues,  grants and  endowments. General  problems of  such  issuers
include  the prospect of a declining  percentage of the population consisting of
"college" age  individuals,  possible  inability  to  raise  tuitions  and  fees
sufficiently  to cover increased  operating costs, the  uncertainty of continued
receipt of  Federal grants  and  state funding,  and government  legislation  or
regulations  which may adversely  affect the revenues or  costs of such issuers.
All of such issuers have been experiencing certain of these problems in  varying
degrees.
 
    BRIDGE AUTHORITY AND TOLLROAD OBLIGATIONS.  Some of the Bonds in a Trust may
be  obligations  of issuers  which derive  their payments  from bridge,  road or
tunnel toll revenues. The revenues of such an issuer could be adversely affected
by competition from toll-free vehicular bridges and roads and alternative  modes
of transportation. Such revenues could also be adversely affected by a reduction
in  the availability of fuel to motorists  or significant increases in the costs
thereof. Specifically, governmental regulations restricting the use of  vehicles
in  the New  York City  metropolitan area may  adversely affect  revenues of the
Triborough Bridge and Tunnel Authority.
 
    DEDICATED-TAX SUPPORTED  BONDS.    Some of  the  Bonds  in a  Trust  may  be
obligations of issuers which are payable from and secured by tax revenues from a
designated  source, which revenues are pledged  to secure the bonds. The various
types of  Bonds described  below differ  in structure  and with  respect to  the
rights of the bondholders to the underlying property. Each type of dedicated-tax
supported  Bond has distinct risks, only some  of which are set forth below. One
type of dedicated-tax supported Bond is secured by the incremental tax  received
on   either  real   property  or   on  sales   within  a   specifically  defined
 
                                      A-4
<PAGE>
geographical area; such tax generally will  not provide bondholders with a  lien
on  the underlying property or revenues. Another type of dedicated-tax supported
Bond is  secured by  a special  tax levied  on real  property within  a  defined
geographical  area in such a manner that the  tax is levied on those who benefit
from the  project; such  bonds typically  provide for  a statutory  lien on  the
underlying  property for unpaid  taxes. A third  type of dedicated-tax supported
Bond may be secured by a tax levied upon the manufacture, sale or consumption of
commodities or upon the license to pursue certain occupations or upon  corporate
privileges  within a taxing jurisdiction. As to any of these types of Bonds, the
ability of  the  designated  revenues  to satisfy  the  interest  and  principal
payments  on such  bonds may be  affected by  changes in the  local economy, the
financial success of the  enterprise responsible for the  payment of the  taxes,
the  value of  any property on  which taxes may  be assessed and  the ability to
collect such  taxes in  a timely  fashion. Each  of these  factors will  have  a
different affect on each distinct type of dedicated-tax supported bonds.
 
    MUNICIPAL LEASE BONDS.  Some of the Bonds in a Trust may be obligations that
are  secured  by lease  payments  of a  governmental  entity. Such  payments are
normally subject to  annual budget  appropriations of  the leasing  governmental
entity.  A governmental  entity that enters  into such a  lease agreement cannot
obligate future  governments to  appropriate  for and  make lease  payments  but
covenants  to take such action as is necessary to include any lease payments due
in its budgets and to make the appropriations therefor. A governmental  entity's
failure to appropriate for and to make payments under its lease obligation could
result  in insufficient funds  available for payment  of the obligations secured
thereby.
 
    ORIGINAL ISSUE  DISCOUNT BONDS  AND STRIPPED  OBLIGATIONS.   Certain of  the
Bonds  in a Trust may be original  issue discount bonds. These Bonds were issued
with nominal  interest rates  less than  the rates  then offered  by  comparable
securities  and as a consequence  were originally sold at  a discount from their
face, or par, values. This original  issue discount, the difference between  the
initial  purchase price and face value, is deemed under current law to accrue on
a daily basis and the accrued  portion is treated as tax-exempt interest  income
for  federal income tax purposes. On sale  or redemption, gain, if any, realized
in excess of the earned  portion of original issue  discount will be taxable  as
capital  gain. See "What is the Tax Status of Unitholders". The current value of
an original issue discount bond reflects the present value of its face amount at
maturity. In a stable interest rate environment, the market value of an original
issue discount bond would  tend to increase  more slowly in  early years and  in
greater increments as the bond approached maturity.
 
    Certain  of the original issue discount bonds  in a Trust may be zero coupon
bonds. Zero coupon bonds do not provide for the payment of any current interest;
the buyer receives only the right to receive a final payment of the face  amount
of  the bond at its maturity. The effect of  owning a zero coupon bond is that a
fixed yield is earned not only on  the original investment but also, in  effect,
on  all  discount  earned  during  the life  of  the  obligation.  This implicit
reinvestment of earnings at the same rate eliminates the risk of being unable to
reinvest the income on such obligation at a rate as high as the implicit  yield,
but  at the same time also eliminates the holder's ability to reinvest at higher
rates in  the  future.  For  this  reason, zero  coupon  bonds  are  subject  to
substantially  greater  price  fluctuations during  periods  of  changing market
interest rates  than are  securities  of comparable  quality that  pay  interest
currently.
 
    Original  issue discount bonds, including zero  coupon bonds, may be subject
to redemption at prices  based on the  issue price plus  the amount of  original
issue   discount  accreted  to  redemption   (the  "accreted  value")  plus,  if
applicable, some premium.  Pursuant to  such call provisions  an original  issue
discount  bond may be called prior to its maturity date at a price less than its
face value. See the  "Schedules of Investments" for  more information about  the
call provisions of portfolio Bonds.
 
                                      A-5
<PAGE>
    Certain of the Bonds in a Trust may be Stripped Obligations, which represent
evidences  of ownership  with respect  to either  the principal  amount of  or a
payment of interest on a tax-exempt  obligation. An obligation is "stripped"  by
depositing  it with  a custodian, which  then effects a  separation in ownership
between the bond and any interest payment which has not yet become payable,  and
issues evidences of ownership with respect to such constituent parts. A Stripped
Obligation  therefore has economic characteristics similar to zero coupon bonds,
as described above.
 
    Each Stripped Obligation has  been purchased at a  discount from the  amount
payable  at maturity. With respect to each Unitholder, the Internal Revenue Code
treats as "original issue discount" that portion of the discount which  produces
a yield to maturity (as of the date of purchase of the Unitholder's Units) equal
to  the lower of the coupon rate of interest on the underlying obligation or the
yield to maturity on the basis of  the purchase price of the Unitholder's  Units
which  is allocable to  each Stripped Obligation.  Original issue discount which
accrues with respect to a Stripped Obligation will be exempt from Federal income
taxation to the  same extent  as interest  on the  underlying obligations.  (See
Section 11, " What Is The Tax Status of Unitholders".)
 
    Unitholders  should consult their own tax advisers with respect to the state
and local tax consequences of owning  original issue discount bonds or  Stripped
Obligations.  Under applicable  provisions governing determination  of state and
local taxes, interest on original  issue discount bonds or Stripped  Obligations
may  be deemed to  be received in  the year of  accrual even though  there is no
corresponding cash payment.
 
4.  COMPOSITION OF TRUSTS
 
Each Trust initially consists  of delivery statements  relating to contracts  to
purchase Bonds (or of such Bonds) as are listed under "Schedules of Investments"
and,  thereafter, of  such Bonds as  may continue to  be held from  time to time
(including certain securities deposited in  the Trust in substitution for  Bonds
not delivered to the Trust or in exchange or substitution for Bonds upon certain
refundings),  together  with  accrued  and  undistributed  interest  thereon and
undistributed cash realized from the disposition of Bonds.
 
    "WHEN-ISSUED"  AND  "DELAYED  DELIVERY"  TRANSACTIONS.    The  contracts  to
purchase  Bonds delivered to  the Trustee represent an  obligation by issuers or
dealers to deliver  Bonds to the  Sponsor for deposit  in the Trusts.  Normally,
"regular  way"  contracts are  settled and  the Bonds  delivered to  the Trustee
within a relatively  short period  of time.  However, certain  of the  contracts
relate  to Bonds which have not been issued  as of the Date of Deposit and which
are commonly referred to  as "when issued"  or "when, as  and if issued"  Bonds.
Although  the Sponsor does not believe it is  likely, one or more of the issuers
of such Bonds might decide not to proceed with such offerings. If such Bonds, or
replacement bonds  described below,  are not  acquired by  a Trust  or if  their
delivery  is  delayed, the  Estimated Current  Returns  and Estimated  Long Term
Returns shown herein may be reduced.  Certain of the contracts for the  purchase
of  Bonds provide for delivery dates after  the date of settlement for purchases
made on  the  Date of  Deposit.  Interest on  such  "when issued"  and  "delayed
delivery"  Bonds accrues to the benefit of Unitholders commencing with the first
settlement date for the Units. However,  in the opinion of counsel,  Unitholders
who  purchase their Units prior to the date such Bonds are actually delivered to
the Trustee must reduce the  tax basis of their  Units for interest accruing  on
such  Bonds during the interval between their purchase of Units and the delivery
of the Bonds because such amounts constitute a return of principal. As a  result
of  such adjustment, the  Estimated Current Returns set  forth herein (which are
based on the Public Offering Price as of  the business day prior to the Date  of
Deposit)  may be  slightly lower than  Unitholders will receive  after the first
year, assuming the Portfolio does not change
 
                                      A-6
<PAGE>
and estimated annual expense does not vary from that set forth under  "Essential
Information  Regarding the  Trusts." Those  Bonds in  each Trust  purchased with
delivery dates after the date  of settlement for purchases  made on the Date  of
Deposit are so noted in the Schedules of Investments.
 
    LIMITED  REPLACEMENT OF CERTAIN BONDS.   Neither the Sponsor nor the Trustee
shall be liable in any  way for any default, failure  or defect in any Bond.  In
the  event of a failure to deliver any  Bond that has been purchased for a Trust
under a contract, including those  Bonds purchased on a  when, as and if  issued
basis  ("Failed Bonds"), the Sponsor is authorized under the Indenture to direct
the Trustee to acquire  other specified Bonds ("Replacement  Bonds") to make  up
the original corpus of the Trust. The Replacement Bonds must be purchased within
20  days after  delivery of notice  of the failed  contract and the  cost to the
Trust (exclusive  of  accrued interest)  may  not  exceed the  amount  of  funds
reserved  for the purchase of  the Failed Bonds. The  Replacement Bonds (i) must
satisfy the criteria previously described  for Bonds originally included in  the
Trust  and, with respect  to Bonds purchased  for a State  Trust, shall have the
benefit of an exemption from state taxation of interest to an extent equal to or
greater than that of  the Bonds they  replace, (ii) must  have a fixed  maturity
date  after the date of purchase of not  less than approximately 15 years in the
case of National or State Trusts, approximately  11 years in the case of a  Long
Intermediate  Trust, approximately 5 years in  the case of Intermediate or State
Intermediate Trusts, approximately 3 years in  the case of a Short  Intermediate
Trust  and approximately 1 year in the case of a Short Term Trust, but not later
than the maturity date of the Failed Bonds, (iii) must be acquired at a cost  to
the  Trust equal to the  cost of the same principal  amount of Bonds provided in
the failed contract and  have a current  return and yield  to maturity not  less
than the current return and yield to maturity of the Failed Bonds and (iv) shall
not  be "when,  as and if  issued" Bonds.  Whenever a Replacement  Bond has been
acquired for a  Trust, the Trustee  shall, within five  days after the  delivery
thereof,  mail or deliver a  notice to all Unitholders  of the Trust involved of
such acquisition. Once the original corpus of the Trust is acquired, the Trustee
will have no power  to vary the  investment of the Trust;  i.e., the Trust  will
have  no managerial  power to  take advantage of  market variation  to improve a
Unitholder's investment.
 
    To the extent the right of  limited substitution described in the  preceding
paragraph  shall not  be utilized  to acquire  Replacement Bonds  for the entire
principal amount of Failed Bonds, the Sponsor shall refund to all Unitholders of
the Trust  involved the  sales  charge attributable  to  such Failed  Bonds  not
replaced,  and the  principal and  accrued interest  attributable to  such Bonds
shall be  distributed not  more than  30 days  after the  determination of  such
failure  or at such earlier time as the  Trustee in its sole discretion deems to
be in  the  interest of  the  Unitholders. Any  such  accrued interest  paid  to
Unitholders will be paid by the Sponsor and, accordingly, will not be treated as
tax-exempt  income. In the event Failed Bonds  in a Trust could not be replaced,
the Net Annual Interest Income per Unit for such Trust would be reduced and  the
Estimated Current Return thereon might be lowered.
 
    SALE,  MATURITY AND REDEMPTION OF BONDS.  Certain of the Bonds may from time
to time  under certain  circumstances be  sold  or redeemed  or will  mature  in
accordance  with their terms. The proceeds from  such events will be used to pay
for  Units  redeemed   or  distributed  to   Unitholders  and  not   reinvested;
accordingly,  no assurance can be given that  a Trust will retain for any length
of time its present size and composition.
 
    All of the Bonds in  each Trust are subject to  being called or redeemed  in
whole  or in  part prior  to their  stated maturities  pursuant to  the optional
redemption provisions described in  the "Schedules of  Investments" and in  most
cases  pursuant to sinking fund, special or extraordinary redemption provisions.
A bond  subject to  optional  call is  one which  is  subject to  redemption  or
refunding    prior   to   maturity   at   the    option   of   the   issuer.   A
 
                                      A-7
<PAGE>
refunding is a method by which a bond issue is redeemed, at or before  maturity,
by  the proceeds of a new bond issue.  A bond subject to sinking fund redemption
is one  which  is  subject to  partial  call  from  time to  time  from  a  fund
accumulated  for the  scheduled retirement  of a  portion of  an issue  prior to
maturity.  Special  or  extraordinary  redemption  provisions  may  provide  for
redemption  of  all or  a portion  of an  issue upon  the occurrence  of certain
circumstances related  to defaults  or unanticipated  changes in  circumstances.
Events  that may  permit or require  the special or  extraordinary redemption of
bonds include, among others: substantial damage to or destruction of the project
for which the proceeds  of the bonds  were used; exercise by  a local, state  or
federal  governmental  unit  of its  power  of  eminent domain  to  take  all or
substantially all of the project for which the proceeds of the bonds were  used;
a  final determination that the interest on the bonds is taxable; changes in the
economic availability  of raw  materials, operating  supplies or  facilities  or
technological  or other  changes which render  the operation of  the project for
which the proceeds of  the bonds were  used uneconomical; changes  in law or  an
administrative  or judicial decree which render the performance of the agreement
under which the proceeds of the bonds were made available to finance the project
impossible or  which  create  unreasonable burdens  or  which  impose  excessive
liabilities,  such as taxes, not imposed on the date the bonds are issued on the
issuer of the bonds or the user of the proceeds of the bonds; an  administrative
or  judicial decree which  requires the cessation  of a substantial  part of the
operations  of  the  project  financed  with  the  proceeds  of  the  bonds;  an
overestimate of the costs of the project to be financed with the proceeds of the
bonds  resulting in excess proceeds which may  be applied to redeem bonds; or an
underestimate of a source of funds securing the bonds resulting in excess  funds
which  may be applied to  redeem bonds. The Sponsor is  unable to predict all of
the circumstances which may result in such redemption of an issue of Bonds.  See
the  discussion of the various  types of bond issues,  above, for information on
the call provisions of such  bonds, particularly single family mortgage  revenue
bonds.
 
    The exercise of redemption or call provisions will (except to the extent the
proceeds of the called Bonds are used to pay for Unit redemptions) result in the
distribution  of  principal and  may  result in  a  reduction in  the  amount of
subsequent interest  distributions; it  may also  affect the  current return  on
Units  of the Trust involved. Redemption pursuant to optional call provisions is
more likely to  occur, and  redemption pursuant to  sinking fund  or special  or
extraordinary  redemption provisions may occur, when  the Bonds have an offering
side evaluation  which represents  a premium  over par.  Redemption pursuant  to
optional  call provisions  may be,  and redemption  pursuant to  sinking fund or
special or extraordinary redemption provisions is likely to be, at a price equal
to the par value of the bonds without any premium (in the case of original issue
discount bonds, such redemption is generally to be made at the issue price  plus
the  amount of original issue discount accreted  to the date of redemption; such
price is referred to  herein as "accreted value").  Because Bonds may have  been
valued  at prices above or below par value or the then current accreted value at
the time Units  were purchased, Unitholders  may realize gain  or loss upon  the
redemption  of portfolio Bonds.  (See Sections 11  and 13 and  the "Schedules of
Investments.")
 
    CERTAIN TAX  MATTERS;  LITIGATION.   Certain  of  the Bonds  in  each  Trust
portfolio  may be subject to  continuing requirements such as  the actual use of
bond proceeds, manner of operation of the project financed from bond proceeds or
rebate of excess  earnings on  bond proceeds that  may affect  the exemption  of
interest  on such Bonds  from Federal income  taxation. Although at  the time of
issuance of each  of the  Bonds in  each Trust an  opinion of  bond counsel  was
rendered as to the exemption of interest on such obligations from Federal income
taxation,  and the issuers covenanted to  comply with all requirements necessary
to retain the tax-exempt status of the Bonds, there can be no assurance that the
 
                                      A-8
<PAGE>
respective issuers  or  other obligors  on  such obligations  will  fulfill  the
various  continuing  requirements  established  upon issuance  of  the  Bonds. A
failure to comply with such requirements may cause a determination that interest
on such  obligations  is  subject  to  Federal  income  taxation,  perhaps  even
retroactively  from the  date of  issuance of  such Bonds,  thereby reducing the
value of the Bonds and subjecting Unitholders to unanticipated tax liabilities.
 
    To the best knowledge of the Sponsor,  there is no litigation pending as  of
the  Date of Deposit in respect of  any Bonds which might reasonably be expected
to have a  material adverse effect  on any of  the Trusts. It  is possible  that
after  the Date of Deposit, litigation may be initiated with respect to Bonds in
any Trust. Any  such litigation may  affect the  validity of such  Bonds or  the
tax-exempt  nature of the interest thereon,  but while the outcome of litigation
of such nature can never be entirely predicted, the opinions of bond counsel  to
the  issuer of  each Bond  on the date  of issuance  state that  such Bonds were
validly issued and that the interest thereon is, to the extent indicated, exempt
from Federal income tax.
 
5.  WHY AND HOW ARE THE BONDS INSURED?
 
INSURANCE ON BONDS IN INSURED TRUSTS
 
Insurance guaranteeing  the  timely payment,  when  due, of  all  principal  and
interest  on the Bonds in each Insured Trust has been obtained by the Sponsor or
by the  issuers or  underwriters  of Bonds  from  the Municipal  Bond  Investors
Assurance  Corporation (the "Insurer"). Some of  the Bonds in each Insured Trust
may be covered by a policy or  policies of insurance obtained by the issuers  or
underwriters  of  the  Bonds  from  Municipal  Bond  Insurance  Association (the
"Association") or Bond Investors Guaranty Insurance Company ("BIG"). The Insurer
has issued a policy or policies of  insurance covering each of the Bonds in  the
Insured Trusts, each policy to remain in force until the payment in full of such
Bonds  and whether or not the Bonds continue  to be held by an Insured Trust. By
the terms  of each  policy the  Insurer will  unconditionally guarantee  to  the
holders  or owners of the Bonds the payment, when due, required of the issuer of
the Bonds of an amount  equal to the principal of  and interest on the Bonds  as
such  payments shall become due but not be paid (except that in the event of any
acceleration of the  due date of  principal by reason  of mandatory or  optional
redemption,  default or otherwise, the payments  guaranteed will be made in such
amounts and  at  such times  as  would  have been  due  had there  not  been  an
acceleration).  The  Insurer will  be responsible  for  such payments,  less any
amounts received by the holders or owners of the Bonds from any trustee for  the
bond  issuers or from  any other sources  other than the  Insurer. The Insurer's
policies relating to  small industrial development  bonds and pollution  control
revenue  bonds also guarantee the full and complete payments required to be made
by or on behalf  of an issuer  of Bonds pursuant  to the terms  of the Bonds  if
there  occurs an event which results in the loss of the tax-exempt status of the
interest on such Bonds,  including principal, interest  or premium payments,  if
any,  as and when thereby required. The Insurer has indicated that its insurance
policies do not insure the payment of  principal or interest on bonds which  are
not required to be paid by the issuer thereof because the bonds were not validly
issued;  as  indicated  under  "What  is the  Tax  Status  of  Unitholders?" the
respective issuing authorities have received  opinions of bond counsel  relating
to  the valid issuance of each of the Bonds in the Insured Trusts. The Insurer's
policy also does not insure against  non-payment of principal of or interest  on
the Bonds resulting from the insolvency, negligence or any other act or omission
of the trustee or other paying agent for the Bonds. The policy is not covered by
the  Property/ Casualty Insurance  Security Fund specified in  Article 76 of the
New York  Insurance Law.  The  policies are  non-cancellable and  the  insurance
premiums have been fully paid on or
 
                                      A-9
<PAGE>
prior  to the Date  of Deposit, either by  the Sponsor or, if  a policy has been
obtained by a Bond issuer, by such issuer.
 
   
    Upon notification from  the trustee  for any bond  issuer or  any holder  or
owner of the Bonds or coupons that such trustee or paying agent has insufficient
funds  to pay any  principal or interest in  full when due,  the Insurer will be
obligated to deposit funds  promptly with State Street  Bank and Trust  Company,
N.A.,  New York, New York, as fiscal  agent for the Insurer, sufficient to fully
cover the deficit. If notice of nonpayment is received on or after the due date,
the Insurer will provide for payment  within one business day following  receipt
of  the notice. Upon payment  by the Insurer of  any Bonds, coupons, or interest
payments, the Insurer shall succeed  to the rights of  the owner of such  Bonds,
coupons or interest payments with respect thereto.
    
 
    The  Insurer is the principal operating subsidiary of MBIA, Inc., a New York
Stock Exchange listed company. MBIA, Inc. is  not obligated to pay the debts  of
or  claims against the  Insurer. The Insurer is  a limited liability corporation
rather than a  several liability association.  The Insurer is  domiciled in  the
State  of New York and licensed to do business in all 50 states, the District of
Columbia and the Commonwealth of Puerto Rico.
 
    As of December  31, 1992  the Insurer had  admitted assets  of $2.6  billion
(audited),  total liabilities of  $1.7 billion (audited),  and total capital and
surplus of  $896  million  (audited) determined  in  accordance  with  statutory
accounting   practices   prescribed   or  permitted   by   insurance  regulatory
authorities. As of September 30, 1993,  the Insurer had admitted assets of  $3.0
billion  (unaudited), total liabilities  of $2.0 billion  (unaudited), and total
capital and surplus of  $951 million (unaudited)  determined in accordance  with
statutory  accounting practices prescribed or  permitted by insurance regulatory
authorities. Copies of the Insurer's  year end financial statements prepared  in
accordance  with statutory accounting practices  are available from the Insurer.
The address of the Insurer is 113 King Street, Armonk, New York 10504.
 
    Effective December 31, 1989, MBIA  Inc. acquired Bond Investors Group,  Inc.
On  January 5, 1990, the  Insurer acquired all of  the outstanding stock of Bond
Investors Group, Inc., the parent of BIG,  now known as MBIA Insurance Corp.  of
Illinois.  Through a reinsurance agreement, BIG has ceded all of its net insured
risks, as well as its unearned premium and contingency reserves, to the  Insurer
and the Insurer has reinsured BIG's net outstanding exposure.
 
    Each  insurance company comprising the Association will be severally and not
jointly obligated  under  the Association  policy  in the  following  respective
percentages:  The  AEtna  Casualty  and  Surety  Company,  33%;  Fireman's  Fund
Insurance Company, 30%;  The Travelers Indemnity  Company, 15%; AEtna  Insurance
Company  (now  known  as CIGNA  Property  and  Casualty Company),  12%;  and The
Continental Insurance Company, 10%.  As a several  obligor, each such  insurance
company  will be  obligated only to  the extent  of its percentage  of any claim
under the  Association  policy and  will  not be  obligated  to pay  any  unpaid
obligation  of any  other member  of the  Association. Each  insurance company's
participation is backed by all of its assets. However, each insurance company is
a multiline insurer involved in several lines of insurance other than  municipal
bond  insurance, and the assets of each insurance company also secure all of its
other insurance policy and surety bond obligations.
 
    The following table sets forth certain unaudited financial information  with
respect  to  the  five  insurance  companies  comprising  the  Association.  The
statistics, which have been furnished by the Association, are as reported by the
insurance  companies  to  the  New  York  State  Insurance  Department  and  are
determined in accordance with statutory accounting principles. No representation
is    made    herein    as   to    the    accuracy   or    adequacy    of   such

information or as to the absence of material adverse changes in such information
subsequent to  the date  thereof.  In addition,  these  numbers are  subject  to
revision  by the  New York State  Insurance Department which,  if revised, could
either increase or decrease the amounts.

    The Moody's  Investors Service  rating of  the Insurer  should be  evaluated
independently  of the  Standard & Poor's  Corporation rating of  the Insurer. No
application has  been  made  to any  other  rating  agency in  order  to  obtain
additional  ratings  on the  Bonds. The  ratings  reflect the  respective rating
agency's current  assessment of  the  creditworthiness of  the Insurer  and  its
ability  to  pay  claims  on  its policies  of  insurance  (See  "Description of
Ratings.") Any further explanation as to  the significance of the above  ratings
may be obtained only from the applicable rating agency.
 
    The  above ratings are not  recommendations to buy, sell  or hold the Bonds,
and such ratings may  be subject to  revision or withdrawal at  any time by  the
rating  agencies. Any downward revision or  withdrawal of either or both ratings
may have an adverse effect on the market price of the Bonds.
 
    Because the insurance on the  Bonds will be effective  so long as the  Bonds
are  outstanding, such insurance  will be taken into  account in determining the
market value of
 
                                      A-11
<PAGE>
the Bonds  and therefore  some  value attributable  to  such insurance  will  be
included  in the value  of the Units  of the Insured  Trusts. The insurance does
not, however, guarantee the market value of the Bonds or of the Units.
 
INSURANCE ON CERTAIN BONDS IN TRADITIONAL TRUSTS
 
    Insurance guaranteeing the timely  payment, when due,  of all principal  and
interest  on certain Bonds in a Traditional  Trust may have been obtained by the
Sponsor, issuer or underwriter  of the particular Bonds  involved or by  another
party.  Such insurance, which  provides coverage substantially  the same as that
obtained with  respect  to  Bonds  in Insured  Trusts  as  described  above,  is
effective  so long as the insured Bond is outstanding and the insurer remains in
business. Insurance relates  only to the  particular Bond and  not to the  Units
offered hereby or to their market value. Insured Bonds have received a rating of
"Aaa"  by  Moody's Investors  Service, Inc.  and/or "AAA"  by Standard  & Poor's
Corporation in recognition of such insurance.
 
    If a Bond  in a Traditional  Trust is insured,  the Schedule of  Investments
will identify the insurer. Such insurance will be provided by Financial Guaranty
Insurance   Company  ("FGIC"),  AMBAC   Indemnity  Corporation  ("AMBAC"),  Bond
Investors Guaranty  Insurance  Company, now  known  as MBIA  Corp.  of  Illinois
("BIG"),   Capital  Guaranty  Insurance  Company  ("CGIC"),  Financial  Security
Assurance,   Inc.   ("FSA"),   Municipal   Bond   Insurance   Association   (the
"Association"),  Municipal  Bond  Investors  Assurance  Corporation  ("MBIA") or
Connie Lee Insurance Company  ("ConnieLee"). The Sponsor  to date has  purchased
and  presently intends  to purchase  insurance for  Bonds in  Traditional Trusts
exclusively from MBIA (see the  preceding disclosure regarding MBIA). There  can
be  no assurance  that any insurer  listed therein  will be able  to satisfy its
commitments in the  event claims  are made in  the future.  However, Standard  &
Poor's  Corporation has rated  the claims-paying ability  of each insurer "AAA,"
and Moody's Investors Service has rated all bonds insured by each such  insurer,
except  ConnieLee, "Aaa." Moody's Investor's Service  gives no ratings for bonds
insured by ConnieLee.
 
    Because any such insurance  will be effective so  long as the insured  Bonds
are  outstanding, such insurance  will be taken into  account in determining the
market value  of  such Bonds  and  therefore  some value  attributable  to  such
insurance  will be included in the value of the Units of the Trust that includes
such Bonds. The insurance does not,  however, guarantee the market value of  the
Bonds or of the Units.
 
6.  HOW IS THE PUBLIC OFFERING PRICE DETERMINED?
 
The  Public Offering Price of the Units of  each Trust is equal to the Trustee's
determination of the aggregate  OFFERING prices of  the Bonds deposited  therein
(minus  any  advancement to  the  principal account  of  the Trust  made  by the
Trustee) plus a sales charge of 5.152% of such value in the case of National and
State Trusts, 4.439%  of such  value in the  case of  Long Intermediate  Trusts,
4.058% of such value in the case of Intermediate Trusts, 3.093% of such value in
the  case of Short Intermediate  Trusts and 2.564% of such  value in the case of
Short Term Trusts, in  each case adding  to the total thereof  cash held by  the
Trust,  if  any,  and  dividing the  sum  so  obtained by  the  number  of Units
outstanding in the Trust. This computation produces a gross underwriting  profit
equal  to 4.90% of the  Public Offering Price in the  case of National and State
Trusts, 4.25% of  the Public  Offering Price in  the case  of Long  Intermediate
Trusts,  3.90% of the Public Offering Price  in the case of Intermediate Trusts,
3.00% of the Public Offering Price in the case of Short Intermediate Trusts  and
2.50% of the Public Offering Price in the case of Short Term Trusts.
 
    The  sales charge applicable to quantity purchases is reduced on a graduated
scale for sales to any purchaser of at least $100,000 or 1,000 Units and will be
applied on whichever
 
                                      A-12
<PAGE>
basis is  more favorable  to the  purchaser. Sales  charges during  the  primary
offering period are as follows:

 *The  breakpoint sales  charge is  also applied on  a dollar  basis utilizing a
  breakpoint equivalent in the above table of $100,000 to 1,000 Units,  $250,000
  to 2,500 Units etc.
 
    For  "secondary market"  sales the  Public Offering  Price per  Unit of each
Trust is determined by adding to the Trustee's determination of the BID price of
each Bond in the Trust  a sales charge determined  in accordance with the  table
set forth below based upon the number of years remaining to the maturity of each
such  Bond, adjusting  the total to  reflect the amount  of any cash  held in or
advanced to the principal account  of the Trust and  dividing the result by  the
number  of Units then outstanding. For  purposes of this calculation, Bonds will
be deemed to mature on  their stated maturity dates  unless: (a) the Bonds  have
been  called for redemption or funds or securities have been placed in escrow to
redeem them on  an earlier  call date,  in which case  such call  date shall  be
deemed to be the date upon which they mature; or (b) such Bonds are subject to a
"mandatory put," in which case such mandatory put date shall be deemed to be the
date upon which they mature.
 
    Pursuant to the terms of the Indenture, the Trustee may terminate a Trust if
the  net asset value of  such Trust, as shown  by any semi-annual evaluation, is
less than 20% of the  original principal amount of the  Trust. In the course  of
regularly  appraising the value of Bonds in each Trust, the Sponsor will attempt
to estimate the  date on which  a Trust's value  will fall below  the 20%  level
based  on anticipated bond events over a five year period, including maturities,
escrow calls and current calls or refundings, assuming certain market rates. The
Sponsor intends from time to time to recommend that certain Trusts whose  values
have  fallen or are anticipated to fall  below the 20% level be terminated based
on certain criteria  which could adversely  affect the Trust's  diversification.
Once  the Sponsor has determined that a Trust's  value has or may fall below the
20% level within a five-year period, for purposes of computing the sales  charge
using the table set forth below, the maturity of each bond in such Trust will be
deemed  to be the earlier of the estimated termination date of the Trust, or the
actual date used  when pricing  the bond under  Municipal Securities  Rulemaking
Board rules and interpretations issued thereunder.
 
    The effect of this method of sales charge calculation will be that different
sales  charge rates will  be applied to  the various Bonds  in a Trust portfolio
based upon  the maturities  of  such Bonds,  in  accordance with  the  following
schedule. As shown, the sales charge on
 
                                      A-13
<PAGE>
Bonds  in each maturity range  (and therefore the aggregate  sales charge on the
purchase) is reduced  with respect to  purchases of at  least $100,000 or  1,000
Units:

 *Breakpoint  sales charges are computed both on a dollar basis and on the basis
  of the  number of  Units purchased,  using the  equivalent of  1,000 Units  to
  $100,000,  2,500 Units to  $250,000, etc., and  will be applied  on that basis
  which is more favorable to the purchaser.
 
    The secondary market sales charges above  are expressed as a percent of  the
net  amount invested; expressed as  a percent of the  Public Offering Price, the
maximum sales charge on  any Trust, including one  consisting entirely of  Bonds
with  16 years  or more to  maturity, would be  5.50% (5.820% of  the net amount
invested). For purposes of illustration, the sales charge on a Trust  consisting
entirely  of Bonds maturing  in 13 to  16 years would  be 5% (5.263%  of the net
amount invested); that on a Trust consisting entirely of Bonds maturing in  five
to  seven years would be 3.5% (3.627% of the net amount invested); and that on a
Trust consisting entirely of Bonds maturing in three to four years would be 2.5%
(2.564% of the net  amount invested). The actual  secondary market sales  charge
included in the Public Offering Price of any particular Trust will depend on the
maturities of the Bonds in the portfolio of such Trust.
 
    At  all  times while  Units are  being  offered for  sale, the  Sponsor will
appraise or cause to  be appraised daily  the value of  the underlying Bonds  in
each  Trust as of 4:00 p.m. eastern time on each day on which the New York Stock
Exchange (the "Exchange") is normally open  and will adjust the Public  Offering
Price  of the Units commensurate with such appraisal. Such Public Offering Price
will be effective for all orders received by a dealer or the Sponsor at or prior
to 4:00 p.m. eastern time on each such day. Orders received after that time,  or
on a day when the Exchange is closed for a scheduled holiday or weekend, will be
held until the next determination of price.
 
    As  more fully set forth  in Section 8, accrued  interest from the preceding
Record Date to, but not including, the settlement date of the transaction  (five
business  days after  purchase) will  be added to  the Public  Offering Price to
determine the purchase price of Units.
 
    The above graduated  sales charges  will apply  on all  purchases of  Nuveen
investment  company  securities on  any one  day  by the  same purchaser  in the
amounts stated, and for this purpose purchases of this Series will be aggregated
with concurrent  purchases of  any other  Series or  of shares  of any  open-end
management  investment company of which the Sponsor is principal underwriter and
with respect to the purchase of which a sales charge is imposed.
 
    Purchases by or for the account of  an individual and his or her spouse  and
children  under 21 years of  age will be aggregated  to determine the applicable
sales charge. The graduated  sales charges are also  applicable to a trustee  or
other  fiduciary  purchasing  securities for  a  single trust  estate  or single
fiduciary account.
 
                                      A-14
<PAGE>
    Units may be purchased at the  public offering price without a sales  charge
by officers or directors and by bona fide, full-time employees of Nuveen, Nuveen
Advisory Corp., Nuveen Institutional Advisory Corp. and The John Nuveen Company,
including  in each case these individuals and their immediate family members (as
defined above).
 
    The initial or primary Public Offering Price  of the Units in each Trust  is
based upon a pro rata share of the OFFERING prices per Unit of the Bonds in such
Trust  plus the  applicable sales charge.  The secondary  market Public Offering
Price of each Trust is based upon a pro rata share of the BID prices per Unit of
the Bonds in such Trust plus the applicable sales charge. The OFFERING prices of
Bonds in a Trust may be expected to average approximately 1% to 2% more than the
BID prices of such Bonds  in the case of  National, Long Intermediate and  State
Trusts,  3/4%  to 1  1/2% in  the  case of  Intermediate and  Short Intermediate
Trusts, and  1/2% to  3/4% in  the case  of Short  Term Trusts.  The  difference
between the bid side evaluation and the offering side evaluation of the Bonds in
each  Trust on the  business day prior  to the Date  of Deposit is  shown in the
discussion of each Trust portfolio.
 
    Whether or not Units are being offered for sale, the Sponsor will  determine
the aggregate value of each Trust as of 4:00 p.m. eastern time: (i) on each June
30 or December 31 (or, if such date is not a business day, the last business day
prior  thereto), (ii) on any day on which  a Unit is tendered for redemption (or
the next succeeding business day  if the date of  tender is a non-business  day)
and (iii) at such other times as may be necessary. For this purpose, a "business
day" shall be any day on which the Exchange is normally open. (See Section 16.)
 
7.  MARKET FOR UNITS
 
During  the  initial public  offering period,  the Sponsor  intends to  offer to
purchase Units of each  Trust at a  price equivalent to the  pro rata share  per
Unit  of the OFFERING prices of the Bonds in such Trust (plus accrued interest).
Afterward, although  it  is not  obligated  to do  so,  the Sponsor  intends  to
maintain  a secondary  market for  Units of  each Trust  at its  own expense and
continuously to offer  to purchase  Units of each  Trust at  prices, subject  to
change  at  any time,  which  are based  upon  the BID  prices  of Bonds  in the
respective portfolios of the Trusts. If the supply of Units of any of the Trusts
of this Series exceeds  demand, or for some  other business reason, the  Sponsor
may discontinue purchases of Units of such Trust at such prices. UNITHOLDERS WHO
WISH  TO DISPOSE OF THEIR UNITS SHOULD INQUIRE OF THE TRUSTEE OR THEIR BROKER AS
TO THE  CURRENT  REDEMPTION PRICE  (SEE  SECTION  19). In  connection  with  its
secondary  marketmaking activities, the Sponsor may from time to time enter into
secondary market  joint  account  agreements with  other  brokers  and  dealers.
Pursuant to such an agreement the Sponsor will purchase Units from the broker or
dealer at the bid price and will place the Units into a joint account managed by
the  Sponsor; sales from  the account will  be made in  accordance with the then
current prospectus and the Sponsor and  the broker or dealer will share  profits
and  losses in  the joint account  in accordance  with the terms  of their joint
account agreement.
 
    Certificates, if any, for Units are  delivered to the purchaser as  promptly
after  the date of settlement (five business days after purchase) as the Trustee
can complete the mechanics of registration. Normally, Certificates, if any,  are
mailed  by  the  Trustee within  48  hours after  registration  instructions are
received. Purchasers of Units to whom Certificates are issued will be unable  to
exercise  any right of redemption until they have received their Certificates as
tender of the Certificate, properly endorsed for transfer. (See Section 19.)
 
    Each Unit  of each  respective Trust  initially offered  by this  Prospectus
represents  that fractional  undivided interest  in such  Trust as  is set forth
under "Essential Information Regarding the Trusts." To the extent that any Units
of any Trust are  redeemed by the  Trustee, the aggregate  value of the  Trust's
assets will decrease by the amount paid to the
 
                                      A-15
<PAGE>
redeeming  Unitholder, but the fractional  undivided interest of each unredeemed
Unit in such Trust  will increase proportionately.  The Sponsor will  initially,
and from time to time thereafter, hold Units in connection with their offering.
 
8.  WHAT IS ACCRUED INTEREST?
 
Accrued  interest is the accumulation of unpaid interest on a bond from the last
day on which  interest thereon  was paid.  Interest on  Bonds in  each Trust  is
accounted  for daily on an accrual basis. For this reason, the purchase price of
Units of a Trust will  include not only the Public  Offering Price but also  the
proportionate  share of  accrued interest  to the  date of  settlement. Interest
accrues to the  benefit of Unitholders  commencing with the  settlement date  of
their purchase transaction.
 
    Accrued interest does not include accrual of original issue discount on zero
coupon  bonds, Stripped Obligations or other original issue discount bonds. (See
"Summary of Portfolios--General Trust Information"  and "What Is The Tax  Status
of Unitholders.")
 
    In  an effort to reduce the amount  of accrued interest that investors would
have to pay in addition to the Public Offering Price, the Trustee has agreed  to
advance  to each Trust the amount of accrued interest due on the Bonds as of the
Date of Deposit (which has been designated  the first Record Date for all  plans
of  distribution). This  accrued interest  will be  paid to  the Sponsor  as the
holder of record of  all Units on  the Date of  Deposit. Consequently, when  the
Sponsor  sells Units of a  Trust, the amount of accrued  interest to be added to
the Public Offering Price to determine the  purchase price of the Units of  such
Trust  purchased by an investor will include only accrued interest from the Date
of Deposit  to, but  not including,  the date  of settlement  of the  investor's
purchase  (five business days  after purchase), less  any distributions from the
related Interest Account.  The Trustee  will recover  its advancements  (without
interest  or  other cost  to the  Trusts)  from interest  received on  the Bonds
deposited in each Trust.
 
    The Trustee has no  cash for distribution to  Unitholders until it  receives
interest  payments on the Bonds in the  Trusts. Since municipal bond interest is
accrued daily but  paid only  semi-annually, during  the initial  months of  the
Trusts,  the Interest Accounts,  consisting of accrued  but uncollected interest
and collected interest  (cash), will  be predominantly  the uncollected  accrued
interest  that is not available for  distribution. In approximately three months
the Trustee will commence regular distributions. Thereafter, assuming each Trust
retains its  original  size  and  composition,  annual  interest  collected  and
distributed  will approximate  the estimated  Net Annual  Interest Income stated
herein. However, the amount  of accrued interest  at any point  in time will  be
greater  than  the  amount that  the  Trustee  will have  actually  received and
distributed to the Unitholders. Therefore, there  will always remain an item  of
accrued interest that is included in the purchase price and the redemption price
of the Units.
 
    Interest  is accounted  for daily and  a proportionate share  of accrued and
undistributed interest computed from the preceding  Record Date is added to  the
daily  valuation of each Unit  of each Trust. (See Sections  3 and 13.) As Bonds
mature, or are redeemed or sold,  the accrued interest applicable to such  bonds
is  collected and subsequently distributed  to Unitholders. Unitholders who sell
or redeem all or a portion of their Units will be paid their proportionate share
of the remaining accrued interest to, but not including, the fifth business  day
following the date of sale or tender.
 
9.  WHAT ARE ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN?
 
The  Estimated Long Term Return for each Trust is a measure of the return to the
investor earned over the  estimated life of the  Trust. The Estimated Long  Term
Return represents an
 
                                      A-16
<PAGE>
average  of  the  yields to  maturity  (or call)  of  the Bonds  in  the Trust's
portfolio calculated in accordance with  accepted bond practice and adjusted  to
reflect  expenses and  sales charges.  Under accepted  bond practice, tax-exempt
bonds are  customarily offered  to investors  on a  "yield price"  basis,  which
involves  computation of yield to maturity or to an earlier call date (whichever
produces the lower yield),  and which takes into  account not only the  interest
payable  on the bonds but also the amortization or accretion to a specified date
of any premium  over or discount  from the  par (maturity) value  in the  bond's
purchase price. In calculating Estimated Long Term Return, the average yield for
the  Trust's portfolio is derived  by weighting each Bond's  yield by the market
value of the Bond and by the amount  of time remaining to the date to which  the
Bond  is priced. Once  the average portfolio  yield is computed,  this figure is
then reduced to reflect estimated expenses  and the effect of the maximum  sales
charge  paid by investors.  The Estimated Long Term  Return calculation does not
take into account the delays in payments to Unitholders for the first few months
of Trust operations, and it  also does not take  into account the difference  in
the  timing of payments to Unitholders who choose quarterly or semi-annual plans
of distribution each of which will reduce the return.
 
    Estimated Current Return  is computed  by dividing the  Net Annual  Interest
Income per Unit by the Public Offering Price. In contrast to Estimated Long Term
Return, Estimated Current Return does not reflect the amortization of premium or
accretion of discount, if any, on the Bonds in the Trust's portfolio. Net Annual
Interest Income per Unit is calculated by dividing the annual interest income to
the Trust, less estimated expenses, by the number of Units outstanding.
 
    Net  Annual Interest  Income per Unit,  used to  calculate Estimated Current
Return, will vary  with changes  in fees  and expenses  of the  Trustee and  the
Evaluator  and with the redemption, maturity, exchange or sale of Bonds. A Trust
may experience expenses and  portfolio changes different  from those assumed  in
the  calculation of Estimated Long  Term Return. There thus  can be no assurance
that the Estimated Current Returns or Estimated Long Term Returns quoted  herein
will  be realized in the future. Since both the Estimated Current Return and the
Estimated Long Term Return quoted  herein are based on  the market value of  the
underlying  Bonds on the business  day prior to the  Date of Deposit, subsequent
calculations of these performance measures will reflect the then current  market
value of the underlying Bonds and may be higher or lower.
 
    A  portion of the  monies received by a  Trust may be  treated, in the first
year only, as a return of principal due to the inclusion in the Trust  portfolio
of  "when-issued"  or  other  Bonds  having delivery  dates  after  the  date of
settlement for purchases  made on  the Date of  Deposit. A  consequence of  this
treatment  is that in the computation of  Estimated Current Return for the first
year, such monies are excluded from Net Annual Interest Income and treated as an
adjustment to the Public Offering  Price. (See "Essential Information  Regarding
the Trusts" and Sections 4 and 11.)
 
    For a statement of the Net Annual Interest Income per Unit under the monthly
plan  of  distribution,  and Estimated  Long  Term Yield  and  Estimated Current
Returns based on the Public Offering Prices of the Trusts in this Series, all as
of the day prior  to the Date of  Deposit, see "Essential Information  Regarding
the Trusts."
 
10.  HOW WAS THE PRICE OF THE BONDS DETERMINED AT THE DATE OF DEPOSIT?
 
The prices at which the Bonds deposited in the Trusts would have been offered to
the  public on the business day prior to  the Date of Deposit were determined by
the Trustee on the basis  of an evaluation of such  Bonds prepared by Kenny  S&P
Evaluation  Services, a  firm regularly engaged  in the  business of evaluating,
quoting or appraising comparable bonds. With respect
 
                                      A-17
<PAGE>
to Bonds in Insured  Trusts and insured Bonds  in Traditional Trusts, Kenny  S&P
Evaluation Services evaluated the Bonds as so insured. (See Section 5).
 
    The  amount by which  the Trustee's determination of  the OFFERING PRICES of
the Bonds deposited  in the Trusts  was greater or  less than the  cost of  such
Bonds  to  the  Sponsor was  PROFIT  OR LOSS  to  the Sponsor  exclusive  of any
underwriting profit.  (See Section  3.)  The Sponsor  also may  realize  FURTHER
PROFIT  OR  SUSTAIN FURTHER  LOSS  as a  result  of fluctuations  in  the Public
Offering Price of the Units. Cash, if  any, made available to the Sponsor  prior
to  the settlement date for a purchase of  Units, or prior to the acquisition of
all Portfolio securities by a Trust, may  be available for use in the  Sponsor's
business, and may be of benefit to the Sponsor.
 
11.  WHAT IS THE TAX STATUS OF UNITHOLDERS?
 
At  the  respective times  of issuance  of  the Bonds  opinions relating  to the
validity thereof and to  the exemption of interest  thereon from Federal  income
tax  were rendered  by bond  counsel to  the respective  issuing authorities. In
addition, with respect to  State Trusts, where applicable,  bond counsel to  the
issuing  authorities rendered opinions  as to the exemption  of interest on such
Bonds, when held by residents  of the state in which  the issuers of such  Bonds
are  located, from state income taxes and certain state or local intangibles and
local income taxes.  For a  discussion of  the tax  status of  State Trusts  see
"Summary  of  Portfolios--  Tax Status"  for  the respective  State  Trust. (See
Sections 2 and 3.)  Neither the Sponsor  nor its counsel  have made any  special
review  for the Trusts of the proceedings  relating to the issuance of the Bonds
or of the basis for the opinions rendered in connection therewith.
 
    Taxpayers  must  disclose  on  their  Federal  tax  returns  the  amount  of
tax-exempt  interest  earned  during  the  year.  Federally  tax-exempt  income,
including income on  Units of the  Trusts, will be  taken into consideration  in
computing the portion, if any, of social security benefits received that will be
included in a taxpayer's gross income subject to the Federal income tax.
 
   
    Gain  realized on the sale or redemption of the Bonds by the Trustee or of a
Unit by  a Unitholder  is includable  in  gross income  for Federal  income  tax
purposes,  and may be includable  in gross income for  state tax purposes. (Such
gain does not  include any amounts  received in respect  of accrued interest  or
accrued  original  issue  discount,  if  any.) It  should  be  noted  that under
provisions of the Revenue Reconciliation Act  of 1993 (the "Tax Act")  described
below  that subject accretion of market discount on tax-exempt bonds to taxation
as ordinary income,  gain realized on  the sale  or redemption of  Bonds by  the
Trustee or of Units by a Unitholder that would have been treated as capital gain
under  prior law is treated as ordinary  income to the extent it is attributable
to accretion of market  discount. Market discount can  arise based on the  price
the  Trust pays  for the Bonds  or the  price a Unitholder  pays for  his or her
Units.
    
 
    In the opinion of Chapman and Cutler, Counsel to the Sponsor, under existing
law:
 
    (1) the Trusts  are not  associations taxable  as corporations  for  Federal
        income  tax purposes. Tax-exempt interest received by each of the Trusts
        on  Bonds  deposited  therein  will  retain  its  status  as  tax-exempt
        interest,  for Federal income tax purposes,  when received by the Trusts
        and when distributed  to the  Unitholders, except  that the  alternative
        minimum  tax and environmental  tax (the "Superfund  Tax") applicable to
        corporate Unitholders  may, in  certain  circumstances, include  in  the
        amount  on which  such taxes  are calculated  a portion  of the interest
        income received by  the Trust.  See "Certain Tax  Matters Applicable  to
        Corporate Unitholders", below;
 
    (2) each  Unitholder of a Trust is considered to  be the owner of a pro rata
        portion of such Trust under Subpart E, subchapter J of Chapter 1 of  the
        Internal Revenue Code of
 
                                      A-18
<PAGE>
        1986  (the "Code") and will have a taxable event when the Trust disposes
        of a Bond  or when the  Unitholder redeems or  sells Units.  Unitholders
        must  reduce the  tax basis  of their Units  for their  share of accrued
        interest received by  the Trust, if  any, on Bonds  delivered after  the
        date  the  Unitholders  pay  for  their  Units  and,  consequently, such
        Unitholders may have an increase in taxable gain or reduction in capital
        loss upon the disposition of such Units.  Gain or loss upon the sale  or
        redemption  of Units is measured by  comparing the proceeds of such sale
        or redemption  with the  adjusted basis  of the  Units. If  the  Trustee
        disposes  of Bonds (whether by sale,  payment at maturity, redemption or
        otherwise), gain or loss is recognized to the Unitholder. The amount  of
        any such gain or loss is measured by comparing the Unitholder's pro rata
        share  of the total proceeds from such disposition with the Unitholder's
        basis for his or  her fractional interest in  the asset disposed of.  In
        the  case  of  a  Unitholder who  purchases  Units,  such  basis (before
        adjustment  for  earned  original  issue  discount  and  amortized  bond
        premium,  if any)  is determined by  apportioning the cost  of the Units
        among each of the Trust assets ratably according to value as of the date
        of acquisition of the Units. The tax cost reduction requirements of said
        Code  relating  to  amortization  of   bond  premium  may,  under   some
        circumstances,  result in the  Unitholder realizing a  taxable gain when
        his or her  Units are  sold or  redeemed for  an amount  equal to  their
        original cost; and
 
    (3) any  amounts paid on defaulted Bonds  held by the Trustee under policies
        of insurance issued with respect to  such Bonds will be excludable  from
        Federal  gross income if, and to the same extent as, such interest would
        have been so excludable if paid by the respective issuer. Paragraph  (2)
        of   this  opinion   is  accordingly   applicable  to   policy  proceeds
        representing maturing interest.
 
In the opinion of Carter, Ledyard & Milburn, counsel to the Trustee, and, in the
absence of a New York Trust from the Series, special counsel for the Series  for
New York tax matters, under existing law:
 
        Under  the income tax laws of the State and City of New York, each Trust
    is not an association taxable as a corporation and the income of each  Trust
    will be treated as the income of the Unitholders.
 
    For  a summary of  each opinion of  special counsel to  the respective State
Trusts for state tax matters, see Section 3.
 
    ALL STATEMENTS IN THE PROSPECTUS CONCERNING EXEMPTION FROM FEDERAL, STATE OR
OTHER TAXES ARE THE OPINION OF COUNSEL AND ARE TO BE SO CONSTRUED.
 
    The redemption of Units in a Trust  by a Unitholder would result in each  of
the  remaining Unitholders of said Trust owning a greater proportionate interest
in the remaining assets  of said Trust. Although  present law does not  directly
address  this matter, it  would appear reasonable  that a remaining Unitholder's
tax basis in  his Units would  include his proportionate  share of any  proceeds
received by the Trust on the sale of bonds which were not distributed to him but
were  instead used by  the Trust to redeem  Units and that his  tax basis in the
remaining assets of the  Trust would accordingly be  increased by such share  of
proceeds, based on the relative fair market value of the remaining assets of the
Trust as of the date of such redemption.
 
    Sections  1288 and 1272 of the Code provide a complex set of rules governing
the accrual of original issue discount. These rules provide that original  issue
discount  accrues either on  the basis of  a constant compound  interest rate or
ratably over the term of the Bond, depending on the date the Bond was issued. In
addition, special  rules apply  if the  purchase  price of  a Bond  exceeds  the
original issue price plus the amount of original issue discount which would have
previously  accrued based upon its issue price (its "adjusted issue price"). The
application of these rules will also vary depending on the value of the Bond  on
the date a Unitholder
 
                                      A-19
<PAGE>
acquires his Units, and the price the Unitholder pays for his Units. The accrual
of  tax-exempt original issue  discount on zero coupon  bonds and other original
issue discount bonds  will result in  an increase in  the Unitholder's basis  in
such obligations and, accordingly, in his basis in his Units.
 
    The  Tax Act subjects tax-exempt  bonds to the market  discount rules of the
Code effective for  bonds purchased  after April  30, 1993.  In general,  market
discount is the amount (if any) by which the stated redemption price at maturity
exceeds an investor's purchase price (except to the extent that such difference,
if  any, is attributable to original issue  discount not yet accrued). Under the
Tax Act, accretion of market discount is taxable as ORDINARY INCOME; under prior
law, the  accretion had  been  treated as  capital  gain. Market  discount  that
accretes  while the Trust holds a Bond would be recognized as ordinary income by
the Unitholders when principal payments are  received on the Bond, upon sale  or
at  redemption (including early  redemption), or upon the  sale or redemption of
his or  her Units,  unless a  Unitholder elects  to include  market discount  in
taxable  income  as  it  accrues.  The market  discount  rules  are  complex and
Unitholders should consult their  tax advisors regarding  these rules and  their
application.
 
    The Internal Revenue Code provides that interest on indebtedness incurred or
continued  to purchase  or carry  obligations, the  interest on  which is wholly
exempt from Federal income taxes, is not deductible. Because each Unitholder  is
treated  for Federal income tax purposes as the owner of a pro rata share of the
Bonds owned by the applicable Trust, interest on borrowed funds used to purchase
or carry Units  of such  Trust will  not be  deductible for  Federal income  tax
purposes.  Under rules used by the Internal Revenue Service for determining when
borrowed funds are  considered used for  the purpose of  purchasing or  carrying
particular  assets, the purchase  of Units may  be considered to  have been made
with borrowed funds even though the borrowed funds are not directly traceable to
the purchase of Units (however, these  rules generally do not apply to  interest
paid  on indebtedness  incurred to  purchase or  improve a  personal residence).
Similar rules are  generally applicable  for state tax  purposes. Special  rules
apply  in  the  case  of  certain  financial  institutions  that  acquire Units.
Investors with questions regarding  these issues should  consult with their  tax
advisers.
 
    In  general,  each  issue of  bonds  in  the Trusts  is  subject  to certain
post-issuance requirements which must  be met in order  for the interest on  the
Bonds to be and remain exempt from Federal income taxation. Bond counsel to each
issuer generally has opined that, assuming continuing compliance by such issuers
with  certain covenants, interest on such Bonds  will continue to be exempt from
Federal income taxation (other than with respect to the application to corporate
Unitholders of the alternative  minimum tax or the  Superfund Tax, as  discussed
below).
 
    For  purposes of computing  the alternative minimum  tax for individuals and
corporations, interest on certain specified tax-exempt private activity bonds is
included as a preference item. The Trusts do not include any such bonds.
 
    For taxpayers  other  than corporations,  net  capital gains  are  presently
subject  to a maximum tax  rate of 28 percent. However,  it should be noted that
legislative proposals are introduced from time to time that affect tax rates and
could affect relative differences at which ordinary income and capital gains are
taxed.
 
    CERTAIN TAX  MATTERS APPLICABLE  TO CORPORATE  UNITHOLDERS. In  the case  of
certain  corporations, the alternative minimum tax  and the Superfund Tax depend
upon the corporation's alternative minimum taxable income ("AMTI"), which is the
corporation's taxable income  with certain  adjustments. One  of the  adjustment
items  used in computing AMTI and the Superfund Tax of a corporation (other than
an S corporation, Regulated Investment Company, Real Estate Investment Trust, or
REMIC)   is   an    amount   equal   to    75%   of   the    excess   of    such
 
                                      A-20
<PAGE>
corporation's  "adjusted  current earnings"  over an  amount  equal to  its AMTI
(before such  adjustment  item  and  the  alternative  tax  net  operation  loss
deduction). Although tax-exempt interest received by each of the Trusts on Bonds
deposited  therein will not be included in  the gross income of corporations for
Federal income tax purposes, "adjusted current earnings" includes all tax-exempt
interest, including interest on all Bonds  in the Trust and tax-exempt  original
issue discount.
 
    Corporate  Unitholders  are urged  to consult  their  own tax  advisers with
respect to the particular tax consequences  to them resulting under the  Federal
tax  law, including the corporate alternative minimum tax, the Superfund Tax and
the branch profits tax imposed by Section 884 of the Code.
 
    EXCEPT AS NOTED ABOVE AND IN SECTION  3, THE EXEMPTION OF INTEREST ON  STATE
AND  LOCAL  OBLIGATIONS FOR  FEDERAL INCOME  TAX  PURPOSES DOES  NOT NECESSARILY
RESULT IN EXEMPTION UNDER THE INCOME OR OTHER TAX LAWS OF ANY STATE OR CITY. THE
LAWS  OF  THE  SEVERAL  STATES  VARY  WITH  RESPECT  TO  THE  TAXATION  OF  SUCH
OBLIGATIONS.
 
12.  WHAT ARE NORMAL TRUST OPERATING EXPENSES?
 
No  annual advisory fee is charged the  Trusts by the Sponsor. The Sponsor does,
however, receive a fee  of $0.17 per  annum per $1,000  principal amount of  the
underlying  Bonds  in each  Trust  for regularly  evaluating  the Bonds  and for
maintaining surveillance over the portfolio. (See Section 16.)
 
    For Traditional Trusts, the Trustee receives for ordinary recurring services
an annual fee computed at $1.08 per $1,000 principal amount of underlying  Bonds
in the Trusts for that portion of each Trust under the monthly distribution plan
and   $0.76  and  $0.57  per  $1,000   principal  amount  of  underlying  Bonds,
respectively, for  those  portions  of each  Trust  representing  quarterly  and
semi-annual  distribution plans;  for Insured  Trusts, the  Trustee receives for
ordinary recurring services an annual fee computed at $1.12 per $1,000 principal
amount of underlying Bonds in  the Trusts for that  portion of each Trust  under
the monthly distribution plan and $0.80 and $0.61 per $1,000 principal amount of
underlying  Bonds, respectively, for  those portions of  each Trust representing
quarterly and semi-annual distribution plans. The Trustee's fee may be  adjusted
provided  that all adjustments upward will  not exceed the cumulative percentage
increase of  the  United  States  Department of  Labor's  Consumer  Price  Index
entitled  "All Services  Less Rent" since  the establishment of  the Trusts. The
Trustee has the use of funds, if  any, being held in the Interest and  Principal
Accounts  of  each  Trust  for future  distributions,  payment  of  expenses and
redemptions. These Accounts are non-interest bearing to Unitholders. Pursuant to
normal banking  procedures, the  Trustee benefits  from the  use of  funds  held
therein.  Part of  the Trustee's  compensation for its  services to  the Fund is
expected to result from such use of these funds.
 
    Premiums for the  policies of insurance  obtained by the  Sponsor or by  the
Bond issuers with respect to the Bonds in the Insured Trusts and with respect to
insured  Bonds in Traditional Trusts have been paid in full prior to the deposit
of the Bonds in the Trusts, and the value of such insurance has been included in
the evaluation of the Bonds in each Trust and accordingly in the Public Offering
Price of Units of each Trust. There  are no annual continuing premiums for  such
insurance.
 
    The Sponsor has borne all costs of creating and establishing the Trusts. The
following  are expenses  of the  Trusts and,  when paid  by or  are owed  to the
Trustee, are secured by  a lien on the  assets of the Trust  or Trusts to  which
such expenses are allocable: (1) the expenses and costs of any action undertaken
by  the  Trustee to  protect  the Trusts  and the  rights  and interests  of the
Unitholders; (2) all taxes and other governmental charges upon the Bonds or  any
part of the Trusts (no such taxes or charges are being levied or made or, to the
knowledge  of the Sponsor, contemplated); (3)  amounts payable to the Trustee as
fees for ordinary
 
                                      A-21
<PAGE>
recurring  services  and  for  extraordinary  non-recurring  services   rendered
pursuant to the Indenture, all disbursements and expenses including counsel fees
(including  fees  of bond  counsel which  the Trustee  may retain)  sustained or
incurred by  the  Trustee  in  connection  therewith;  and  (4)  any  losses  or
liabilities  accruing to  the Trustee without  negligence, bad  faith or willful
misconduct on its part. The Trustee is  empowered to sell Bonds in order to  pay
these  amounts if funds  are not otherwise available  in the applicable Interest
and Principal Accounts.
 
    The Indenture requires each Trust  to be audited on  an annual basis at  the
expense  of the Trust by independent public accountants selected by the Sponsor.
The Trustee  shall not  be  required, however,  to cause  such  an audit  to  be
performed  if its cost to a Trust shall exceed $.05 per Unit on an annual basis.
Unitholders of a  Trust covered by  an audit may  obtain a copy  of the  audited
financial statements upon request.
 
13.  WHEN ARE DISTRIBUTIONS MADE TO UNITHOLDERS?
 
Interest received by the Trustee on the Bonds in each Trust, including that part
of  the proceeds of  any disposition of Bonds  which represents accrued interest
and including  any insurance  proceeds representing  interest due  on  defaulted
Bonds,  shall be credited to the "Interest  Account" of such Trust and all other
moneys received by the Trustee shall  be credited to the "Principal Account"  of
such Trust.
 
    The  pro rata share of  cash in the Principal Account  in each Trust will be
computed as of each semi-annual Record Date and distributions to the Unitholders
as of such Record Date will be made on or shortly after the fifteenth day of the
month. Proceeds received from the disposition, including sale, call or maturity,
of any of the Bonds and all amounts  paid with respect to zero coupon bonds  and
Stripped  Obligations will be held  in the Principal Account  and either used to
pay for Units  redeemed or distributed  on the Distribution  Date following  the
next semi-annual Record Date. The Trustee is not required to make a distribution
from  the  Principal  Account  of  any Trust  unless  the  amount  available for
distribution in such account equals at least ten cents per Unit.
 
    The pro rata share of the Interest Account in each Trust will be computed by
the Trustee each month as of each Record Date and distributions will be made  on
or  shortly after the fifteenth day of the month to Unitholders of such Trust as
of the Record Date who are entitled to distributions at that time under the plan
of distribution chosen. Persons who purchase  Units between a Record Date and  a
Distribution Date will receive their first distribution on the Distribution Date
following the next Record Date under the applicable plan of distribution.
 
    Purchasers  of  Units  who desire  to  receive interest  distributions  on a
monthly or quarterly basis may elect to do so at the time of purchase during the
initial public offering  period. Those indicating  no choice will  be deemed  to
have  chosen the  semi-annual distribution  plan. All  Unitholders, however, who
purchase Units during the  initial public offering period  and who hold them  of
record on the first Record Date will receive the first distribution of interest.
Thereafter, Record Dates for monthly distributions will be the first day of each
month;  Record  Dates  for quarterly  distributions  will  be the  first  day of
February,  May,  August   and  November;  and   Record  Dates  for   semi-annual
distributions will be the first day of May and November.
 
    Details  of distributions  per Unit  of each  Trust under  the various plans
based upon estimated Net Annual Interest Income at the Date of Deposit are shown
in the tables appearing  in Section 3. The  amount of the regular  distributions
will  remain the same so long as each Trust portfolio remains the same, and will
generally change when Bonds are redeemed, mature or are sold.
 
                                      A-22
<PAGE>
    The plan of  distribution selected  by a  Unitholder will  remain in  effect
until  changed.  Unitholders  purchasing  Units  in  the  secondary  market will
initially receive distributions  in accordance  with the election  of the  prior
owner.  Unitholders desiring to change  their plan of distribution  may do so by
sending  a   written   notice  requesting   the   change,  together   with   any
Certificate(s),  to  the  Trustee. The  notice  and any  Certificate(s)  must be
received by  the  Trustee not  later  than the  semi-annual  Record Date  to  be
effective   as  of   the  semi-annual  distribution   following  the  subsequent
semi-annual Record  Date. Unitholders  are requested  to make  any such  changes
within  45 days prior to the applicable Record Date. Certificates should only be
sent by registered or certified mail to minimize the possibility of their  being
lost or stolen. (See Section 18.) If no notice is received in proper form by the
Trustee,  the Unitholder  will be  deemed to have  elected to  continue the same
plan.
 
    As of the first day of each month the Trustee will deduct from the  Interest
Account  of a Trust or, to the extent funds are not sufficient therein, from the
Principal Account of  a Trust, amounts  needed for payment  of expenses of  such
Trust.  The Trustee also may withdraw from said accounts such amount, if any, as
it deems necessary to establish a  reserve for any governmental charges  payable
out  of such Trust. Amounts  so withdrawn shall not be  considered a part of the
Trust's assets until such time  as the Trustee shall return  all or any part  of
such amounts to the appropriate account.
 
    For  the purpose  of minimizing fluctuations  in the  distributions from the
Interest Account of a Trust, the  Trustee is authorized to advance such  amounts
as may be necessary to provide for interest distributions of approximately equal
amounts.  The  Trustee  shall  be reimbursed,  without  interest,  for  any such
advances from funds in the Interest Account  of such Trust. It is expected  that
collections  of interest, except during  the first few months  after the Date of
Deposit, will be in such amounts that it will not be necessary for  advancements
to be made by the Trustee.
 
    The  Trustee  shall withdraw  from the  Interest  Account and  the Principal
Account of a  Trust such amounts  as may  be necessary to  cover redemptions  of
Units of such Trust by the Trustee. (See Section 19.)
 
    Funds  which are available for future distributions, redemptions and payment
of expenses are held in accounts  which are non-interest bearing to  Unitholders
and are available for use by the Trustee pursuant to normal banking procedures.
 
14.  ACCUMULATION PLAN
 
The  Sponsor, John Nuveen & Co.  Incorporated, is also the principal underwriter
of the  Nuveen Municipal  Bond Fund,  Inc. (the  "Bond Fund"),  Nuveen  Tax-Free
Reserves, Inc. ("Tax-Free Reserves"), Nuveen California Tax-Free Fund, Inc. (the
"California  Fund"),  Nuveen Tax-Free  Bond Fund,  Inc. ("Tax-Free  Bond Fund"),
Nuveen Insured Tax-Free  Bond Fund, Inc.  (the "Insured Bond  Fund") and  Nuveen
Tax-Free  Money  Market Fund,  Inc.  (the "Money  Market  Fund") and  the Nuveen
Multistate  Tax-Free  Trust  (the  "Multistate  Trust").  Each  of  these  funds
(together,  the  "Accumulation Funds")  is  an open-end,  diversified management
investment  company  into  which  Unitholders  may  choose  to  reinvest   Trust
distributions  automatically,  without any  sales  charge. (Reinvestment  in the
California Fund is available only  to Unitholders who are California  residents.
Reinvestment in the State Portfolios of the Tax-Free Bond Fund, the Insured Bond
Fund,  the  Money Market  Fund and  the  Multistate Trust  is available  only to
Unitholders who  are residents  of  the states  for  which such  portfolios  are
named.)  Unitholders may reinvest  both interest and  principal distributions or
principal distributions only. Each  Accumulation Fund has investment  objectives
which  differ in  certain respects from  those of  the Trusts and  may invest in
securities which would not be eligible for deposit in the Trusts. The investment
adviser to  each Accumulation  Fund  is Nuveen  Advisory Corp.,  a  wholly-owned
subsidiary of the Sponsor. The following is a
 
                                      A-23
<PAGE>
general   description  of  the  investment   objectives  and  policies  of  each
Accumulation Fund. For a more detailed description, Unitholders should read  the
prospectus of the Accumulation Fund in which they are interested.
 
THE BOND FUND
 
    The  Bond  Fund has  the  objective of  providing,  through investment  in a
professionally managed portfolio of long-term  municipal bonds, as high a  level
of  current interest income exempt from Federal income tax as is consistent with
preservation of capital. The Bond Fund  may include in its portfolio  tax-exempt
bonds  rated Baa or BBB or better by Moody's or Standard & Poor's, unrated bonds
which, in the  opinion of  the investment adviser,  have credit  characteristics
equivalent  to  bonds  rated  Baa  or  BBB  or  better,  and  certain  temporary
investments, including securities the interest income from which may be  subject
to Federal income tax.
 
TAX-FREE RESERVES
 
    Tax-Free  Reserves is a  "money market" fund that  includes in its portfolio
only obligations  maturing  within  one  year  from  the  date  of  acquisition,
maintains an average maturity of all investments of 120 days or less, values its
portfolio at amortized cost and seeks to maintain a net asset value of $1.00 per
share. It provides checkwriting and expedited wire redemption privileges for its
shareholders.   Tax-Free  Reserves  has  the  objective  of  providing,  through
investment in  a professionally  managed portfolio  of high  quality  short-term
municipal  obligations, as high  a level of current  interest income exempt from
Federal income  tax  as is  consistent  with  preservation of  capital  and  the
maintenance  of  liquidity.  Tax-Free  Reserves  may  include  in  its portfolio
municipal obligations rated Aaa, Aa, MIG-1, VMIG-1 or Prime-1 by Moody's or AAA,
AA, SP-1 or A-1 by Standard & Poor's, unrated municipal obligations that, in the
opinion of the  investment adviser,  have credit  characteristics equivalent  to
obligations   rated  as  above,  tax-exempt   obligations  backed  by  the  U.S.
Government, and temporary investments that may be subject to Federal income tax.
 
THE CALIFORNIA FUND
 
    The California Fund has  the objective of  providing, through investment  in
professionally managed portfolios of California municipal obligations, as high a
level  of current interest income exempt from both Federal and California income
taxes as is consistent with the investment policies of each of the portfolios of
the California Fund  and with  preservation of  capital. Each  portfolio of  the
California  Fund may include  temporary investments that may  be subject to tax.
California Unitholders may reinvest in one of three portfolios of the California
Fund: The Nuveen California Tax-Free  Value Fund, the Nuveen California  Insured
Tax-Free Value Fund and the Nuveen California Tax-Free Money Market Fund.
 
    The  Nuveen California  Tax-Free Value  Fund invests  primarily in long-term
investment grade  California tax-exempt  bonds (I.E.,  bonds rated  in the  four
highest  categories by Moody's  or Standard &  Poor's or, if  unrated, that have
equivalent credit characteristics). The Nuveen California Insured Tax-Free Value
Fund invests  primarily in  the same  type of  investments as  the Special  Bond
Portfolio, each of which is covered by insurance guaranteeing the timely payment
of  principal  and  interest  or  is backed  by  a  deposit  of  U.S. Government
securities.
 
    The Nuveen  California  Tax-Free  Money Market  Fund  invests  primarily  in
high-quality  short term  California tax-exempt money  market instruments (I.E.,
obligations rated in the two highest categories by Moody's or Standard &  Poor's
or,  if unrated,  that have  equivalent credit  characteristics). This portfolio
will include  only  obligations  maturing  within one  year  from  the  date  of
acquisition, will maintain an average maturity of all investments of 120 days or
less, will value its portfolio at amortized cost and will seek to maintain a net
asset
 
                                      A-24
<PAGE>
value  of  $1.00 per  share. The  Nuveen California  Tax-Free Money  Market Fund
provides for an expedited wire redemption privilege.
 
THE TAX-FREE BOND FUND
 
    The Tax-Free Bond Fund consists  of the Nuveen Massachusetts Tax-Free  Value
Fund,  the Nuveen New York  Tax-Free Value Fund, the  Nuveen Ohio Tax-Free Value
Fund, and the Nuveen  New Jersey Tax-Free Value  Fund, which are each  available
for  reinvestment to Unitholders who  are residents of the  state for which such
portfolio is  named. The  Tax-Free Bond  Fund has  the objective  of  providing,
through  investment in a professionally managed portfolio of municipal bonds, as
high a level of current interest income exempt both from Federal income tax  and
from  the  income  tax  imposed  by  each  portfolio's  designated  state  as is
consistent with preservation of capital. The  Tax-Free Bond Fund may include  in
each  of its  portfolios tax-exempt  bonds rated Baa  or BBB  or better; unrated
bonds  which,  in   the  opinion   of  the  investment   adviser,  have   credit
characteristics  equivalent to  bonds rated  Baa or  BBB or  better; and certain
temporary investments, including securities the  interest income from which  may
be subject to Federal and state income tax.
 
THE INSURED BOND FUND
 
    The  Insured Bond Fund  consists of the Nuveen  Insured Municipal Bond Fund,
the Nuveen Massachusetts  Insured Tax-Free Value  Fund and the  Nuveen New  York
Insured  Tax-Free  Value  Fund, which  are  each available  for  reinvestment to
Unitholders. (The Massachusetts and  New York Portfolios  are available only  to
those  Unitholders who  are residents  of the state  for which  the portfolio is
named.) The Insured Bond Fund has the objective of providing, through investment
in professionally managed  portfolios of  municipal bonds,  as high  a level  of
current  interest income exempt from both Federal income tax and, in the case of
designated state portfolios,  from the  income tax imposed  by each  portfolio's
designated  state, as  is consistent with  preservation of  capital. The Insured
Bond Fund may include in each of its portfolios the same type of investments  as
the  Tax-Free Bond Fund, each of which  is covered by insurance guaranteeing the
timely payment of  principal and  interest or  is backed  by a  deposit of  U.S.
Government securities.
 
THE MONEY MARKET FUND
 
    The  Money Market Fund  consists of the  Nuveen Massachusetts Tax-Free Money
Market Fund and the Nuveen New York  Tax-Free Money Market Fund, which are  each
available  for reinvestment  to Unitholders who  are residents of  the state for
which such portfolio is named. The Money Market Fund includes in its  portfolios
only  obligations  maturing  within  one  year  from  the  date  of acquisition,
maintains an average  maturity of  120 days or  less, values  its portfolios  at
amortized  cost and seeks to maintain a net  asset value of $1.00 per share. The
Money Market  Fund  has  the  objective  of  providing,  through  investment  in
professionally   managed  portfolios   of  high   quality  short-term  municipal
obligations, as high a level of current interest income exempt both from Federal
income tax and from the income tax imposed by each portfolio's designated  state
as  is consistent with stability of  principal and the maintenance of liquidity.
The  Money  Market  Fund  may  include  in  each  of  its  portfolios  municipal
obligations  rated Aaa, Aa, MIG-1, MIG-2, VMIG-1,  VMIG-2, Prime 1 or Prime 2 by
Moody's or  AAA, AA,  SP-1,  SP-2, A-1  or A-2  by  Standard &  Poor's;  unrated
municipal  obligations  that, in  the opinion  of  the investment  adviser, have
credit characteristics equivalent to obligations  rated as above; and  temporary
investments that may be subject to Federal and state income tax.
 
                                      A-25
<PAGE>
THE MULTISTATE TRUST
 
    The Multistate Trust consists of the Nuveen Arizona Tax-Free Value Fund, the
Nuveen Florida Tax-Free Value Fund, the Nuveen Maryland Tax-Free Value Fund, the
Nuveen  Michigan Tax-Free Value Fund, the Nuveen New Jersey Tax-Free Value Fund,
the Nuveen Pennsylvania  Tax-Free Value Fund  and the Nuveen  Virginia Tax  Free
Value  Fund, which  are each available  for reinvestment to  Unitholders who are
residents of the state for which  such portfolio is named. The Multistate  Trust
has  the objective of providing, through  investment in a professionally managed
portfolio of municipal bonds, as high a level of current interest income  exempt
from  both regular Federal  income tax and the  applicable state personal income
tax as is  consistent with  preservation of  capital. The  Multistate Trust  may
include  in each  of its  portfolios tax-exempt  bonds rated  "Baa" or  "BBB" or
better, unrated bonds  which, in  the opinion  of the  investment advisor,  have
credit  characteristics  equivalent to  bonds rated  "baa"  or "BBB"  or better,
limited to  no more  than 20%  of  the Multistate  Trust's assets,  and  certain
temporary investments that may be subject to Federal and state income tax.
 
    Each  person who purchases Units of a  Trust may become a participant in the
Accumulation Plan and elect  to have his  or her distributions  on Units of  the
Trust  invested directly in shares of one of the Accumulation Funds. Reinvesting
Unitholders  may  select  any  interest  distribution  plan.  Thereafter,   each
distribution  of  interest  income  or  principal  on  the  participant's  Units
(principal only in  the case of  a Unitholder  who has chosen  to reinvest  only
principal  distributions) will, on the applicable distribution date, or the next
day on which the New  York Stock Exchange is  normally open ("business day")  if
the  distribution  date is  not  a business  day,  automatically be  received by
Shareholder Services, Inc., transfer agent  for each of the Accumulation  Funds,
on  behalf of such participant  and applied on that  date to purchase shares (or
fractions thereof)  of  the Accumulation  Fund  chosen  at net  asset  value  as
computed  as of 4:00 p.m. eastern time on each such date. All distributions will
be reinvested  in the  Accumulation Fund  chosen  and no  part thereof  will  be
retained  in a separate  account. These purchases  will be made  without a sales
charge.
 
    Shareholder Services, Inc. will mail to each participant in the Accumulation
Plan a quarterly  statement containing  a record of  all transactions  involving
purchases of Accumulation Fund shares (or fractions thereof) with Trust interest
distributions or as a result of reinvestment of Accumulation Fund dividends. Any
distribution  of principal used to purchase  shares of an Accumulation Fund will
be separately  confirmed by  Shareholder Services,  Inc. Unitholders  will  also
receive   distribution  statements  from  the   Trustee  detailing  the  amounts
transferred to their Accumulation Fund accounts.
 
    Participants may at any time, by so notifying the Trustee in writing,  elect
to  change  the  Accumulation  Fund into  which  their  distributions  are being
reinvested, to change from principal  only reinvestment to reinvestment of  both
principal and interest or vice versa, or to terminate their participation in the
Accumulation  Plan altogether and receive future distributions on their Units in
cash. There will be no  charge or other penalty for  such change of election  or
termination.
 
    The  character of  Trust distributions for  income tax  purposes will remain
unchanged even if they are reinvested in an Accumulation Fund.
 
15.  HOW DETAILED ARE REPORTS TO UNITHOLDERS?
 
The Trustee  shall  furnish Unitholders  of  a  Trust in  connection  with  each
distribution,  a statement of the amount of  interest and, if any, the amount of
other receipts (received  since the preceding  distribution) being  distributed,
expressed  in each case  as a dollar  amount representing the  pro rata share of
each Unit of a Trust outstanding and a year to date summary of all distributions
paid  on  said   Units.  Within   a  reasonable   period  of   time  after   the
 
                                      A-26
<PAGE>
end  of each calendar year, the Trustee shall  furnish to each person who at any
time during the calendar year was a registered Unitholder of a Trust a statement
with respect to  such Trust (i)  as to the  Interest Account: interest  received
(including  amounts  representing  interest  received  upon  any  disposition of
Bonds), and, except  for any  State Trust, the  percentage of  such interest  by
states  in which the issuers  of the Bonds are  located, deductions for fees and
expenses of such Trust, redemption of Units and the balance remaining after such
distributions and deductions,  expressed in  each case  both as  a total  dollar
amount  and as  a dollar  amount representing  the pro  rata share  of each Unit
outstanding on the  last business  day of  such calendar  year; (ii)  as to  the
Principal  Account: the dates of  disposition of any Bonds  and the net proceeds
received therefrom (excluding  any portion representing  accrued interest),  the
amount  paid for purchase of Replacement  Bonds, the amount paid upon redemption
of Units, deductions for  payment of applicable taxes  and fees and expenses  of
the  Trustee, and the balance remaining  after such distributions and deductions
expressed both as a total dollar amount and as a dollar amount representing  the
pro  rata  share of  each  Unit outstanding  on the  last  business day  of such
calendar year;  (iii)  a  list  of  the Bonds  held  and  the  number  of  Units
outstanding  on the last business day of such calendar year; (iv) the Unit Value
based upon the last computation thereof made during such calendar year; and  (v)
amounts actually distributed during such calendar year from the Interest Account
and  from  the Principal  Account, separately  stated,  expressed both  as total
dollar amounts and  as dollar amounts  representing the pro  rata share of  each
Unit outstanding.
 
    Each  annual statement will reflect pertinent  information in respect of all
plans of distribution so that Unitholders may be informed regarding the  results
of other plans of distribution.
 
16.  UNIT VALUE AND EVALUATION
 
The  value of each  Trust is determined by  the Sponsor on the  basis of (1) the
cash on hand in the Trust or moneys  in the process of being collected, (2)  the
value  of the Bonds in  the Trust based on  the BID prices of  the Bonds and (3)
interest  accrued  thereon   not  subject  to   collection,  LESS  (1)   amounts
representing  taxes or governmental charges payable out of the Trust and (2) the
accrued expenses of the Trust. The result of such computation is divided by  the
number  of Units of such  Trust outstanding as of  the date thereof to determine
the per Unit value ("Unit Value") of  such Trust. The Sponsor may determine  the
value  of the Bonds in each Trust (1) on  the basis of current BID prices of the
Bonds obtained from dealers or brokers who customarily deal in bonds  comparable
to  those held by the Trust, (2) if bid  prices are not available for any of the
Bonds, on the basis of bid prices for comparable bonds, (3) by causing the value
of the Bonds to be determined by  others engaged in the practice of  evaluating,
quoting  or appraising comparable bonds or (4)  by any combination of the above.
Although the Unit Value of each Trust is  based on the BID prices of the  Bonds,
the Units are sold initially to the public at the Public Offering Price based on
the OFFERING prices of the Bonds.
 
    Because  the insurance obtained  by the Sponsor  or by the  issuers of Bonds
with respect to  the Bonds in  the Insured  Trusts and with  respect to  insured
Bonds  in Traditional Trusts is effective so long as such Bonds are outstanding,
such insurance will be  taken into account in  determining the bid and  offering
prices  of such  Bonds and therefore  some value attributable  to such insurance
will be included in the value of Units of Trusts that include such Bonds.
 
17.  HOW UNITS OF THE TRUSTS ARE DISTRIBUTED TO THE PUBLIC
 
John Nuveen & Co. Incorporated is the Sponsor and sole Underwriter of the Units.
It is  the  intention  of  the  Sponsor  to  qualify  Units  of  National,  Long
Intermediate,  Intermediate, Short Intermediate  and Short Term  Trusts for sale
under the laws of substantially all of the states,
 
                                      A-27
<PAGE>
and Units of State  Trusts only in the  state for which the  Trust is named  and
selected other states.
 
    Promptly following the deposit of Bonds in exchange for Units of the Trusts,
it  is the practice of the Sponsor to place all of the Units as collateral for a
letter or letters of credit from one or more commercial banks under an agreement
to release such Units from time to  time as needed for distribution. Under  such
an  arrangement  the Sponsor  pays  such banks  compensation  based on  the then
current interest  rate. This  is  a normal  warehousing arrangement  during  the
period of distribution of the Units to public investors.
 
    The  Sponsor plans to allow a discount  to brokers and dealers in connection
with  the  primary  distribution   of  Units  and   also  in  secondary   market
transactions. The primary market discounts are as follows:
 
<TABLE>

</TABLE>
 
* The  discount  is  also  applied  on a  dollar  basis  utilizing  a breakpoint
  equivalent in the above table of $100,000 to 1,000 Units, etc.
 
    The Sponsor currently intends  to maintain a secondary  market for Units  of
each  Trust. See  Section 7.  The amount of  the dealer  concession on secondary
market purchases of Trust Units through the Sponsor will be computed based  upon
the  value  of the  Bonds in  the  Trust portfolio,  including the  sales charge
computed as described in Section 6, and adjusted to reflect the cash position of
the Trust principal  account, and will  vary with  the size of  the purchase  as
shown in the following table:

 *Breakpoint sales charges and related dealer concessions are computed both on a
  dollar  basis and  on the basis  of the  number of Units  purchased, using the
  equivalent of 1,000 Units to $100,000, 2,500 Units to $250,000, etc., and will
  be applied on that basis which is more favorable to the purchaser.
 
    The Sponsor reserves the  right to change  the foregoing dealer  concessions
from time to time.
 
    Certain  commercial banks are making Units  of the Trusts available to their
customers on  an agency  basis. A  portion of  the sales  charge paid  by  these
customers  is retained by or  remitted to the banks in  the amounts shown in the
above table.  The Glass-Steagall  Act prohibits  banks from  underwriting  Trust
Units;  the Act  does, however, permit  certain agency  transactions and banking
regulators have not indicated that these particular agency
 
                                      A-28
<PAGE>
transactions are not  permitted under  the Act. In  Texas and  in certain  other
states,  any bank making  Units available must be  registered as a broker-dealer
under state law.
 
    To facilitate the handling of transactions, sales of Units shall be  limited
to  transactions involving a minimum of either  $5,000 or 50 Units, whichever is
less. The Sponsor reserves the right to  reject, in whole or in part, any  order
for the purchase of Units.
 
18.  OWNERSHIP AND TRANSFER OF UNITS
 
The  ownership  of Units  is evidenced  either by  Certificates executed  by the
Trustee or by  book entry positions  recorded on  the books and  records of  the
Trustee.  The Trustee is authorized  to treat as the  owner of Units that person
who at  the  time is  registered  as  such on  the  books of  the  Trustee.  Any
Unitholder  who  holds  a Certificate  may  change  to book  entry  ownership by
submitting to the Trustee the Certificate along with a written request that  the
Units  represented by such Certificate  be held in book  entry form. Likewise, a
Unitholder who holds Units in book entry form may obtain a Certificate for  such
Units  by written request to the Trustee.  Units may be held in denominations of
one Unit or any multiple or fraction thereof. Fractions of Units are computed to
three decimal  places. Any  Certificates issued  will be  numbered serially  for
identification,  and are issued  in fully registered  form, transferable only on
the books  of the  Trustee. Book  entry Unitholders  will receive  a Book  Entry
Position Confirmation reflecting their ownership.
 
    Certificates  for  Units will  bear an  appropriate  notation on  their face
indicating which plan of distribution has been selected. When a change is  made,
the   existing  Certificates  must  be  surrendered   to  the  Trustee  and  new
Certificates issued to  reflect the  currently effective  plan of  distribution.
There will be no charge for this service. Holders of book entry Units can change
their  plan of distribution  by making a  written request to  the Trustee, which
will issue a new Book Entry Position Confirmation to reflect such change.
 
    Units are transferable by  making a written request  to the Trustee and,  in
the  case of Units  evidenced by Certificate(s),  by presenting and surrendering
such Certificate(s) to the  Trustee, at its corporate  trust office in New  York
City, properly endorsed or accompanied by a written instrument or instruments of
transfer. The Certificate(s) should be sent registered or certified mail for the
protection  of the Unitholder.  Each Unitholder must  sign such written request,
and such Certificate(s) or transfer instrument,  exactly as his name appears  on
(a)  the face of the Certificate(s) representing the Units to be transferred, or
(b) the  Book  Entry  Position  Confirmation(s) relating  to  the  Units  to  be
transferred.  Such signature(s)  must be guaranteed  by a member  of an approved
Medallion Guarantee Program or in such other manner as may be acceptable to  the
Trustee.  In certain instances the Trustee may require additional documents such
as, but not limited to,  trust instruments, certificates of death,  appointments
as  executor or administrator or  certificates of corporate authority. Mutilated
Certificates must  be surrendered  to the  Trustee in  order for  a  replacement
Certificate to be issued.
 
    Although  at the date hereof  no charge is made  and none is contemplated, a
Unitholder may be  required to  pay $2.00 to  the Trustee  for each  Certificate
reissued or transfer of Units requested and to pay any governmental charge which
may be imposed in connection therewith.
 
REPLACEMENT OF LOST, STOLEN OR DESTROYED CERTIFICATES.
 
    To  obtain a new  Certificate replacing one  that has been  lost, stolen, or
destroyed,  the   Unitholder   must   furnish  the   Trustee   with   sufficient
indemnification and pay such expenses as the Trustee may incur.
 
    The  indemnification protects the  Trustee, Sponsor, and  Trust from risk if
the original Certificate is presented for transfer or redemption by a person who
purchased it  in good  faith,  for value  and without  notice  of any  fraud  or
irregularity.
 
                                      A-29
<PAGE>
    This  indemnification  must  be in  the  form  of an  Open  Penalty  Bond of
Indemnification. The premium for  such an indemnity bond  may vary from time  to
time,  but  currently  amounts  to 1  1/2%  of  the market  value  of  the Units
represented by the  Certificate. In the  case however,  of a Trust  as to  which
notice of termination has been given, the premium currently amounts to 1% of the
market value of the Units represented by such Certificate.
 
19.  HOW UNITS MAY BE REDEEMED WITHOUT CHARGE
 
Unitholders  may redeem all or a portion of  their Units by (1) making a written
request for such redemption (book entry Unitholders may use the redemption  form
on the reverse side of their Book Entry Position Confirmation) to the Trustee at
its  corporate trust office in New York City (redemptions of 1,000 Units or more
will require a signature  guarantee), (2) in  the case of  Units evidenced by  a
Certificate, by also tendering such Certificate to the Trustee, duly endorsed or
accompanied  by  proper instruments  of transfer  with signatures  guaranteed as
explained in  Section  18 above,  and  (3) payment  of  applicable  governmental
charges,  if any.  Certificates should be  sent only by  registered or certified
mail to minimize  the possibility of  their being  lost or stolen.  In order  to
effect  a  redemption of  Units evidenced  by a  Certificate, a  Unitholder must
tender the Certificate to the Trustee or provide satisfactory indemnity required
in connection with lost, stolen or  destroyed Certificates (See Section 18).  No
redemption  fee will be charged. A Unitholder may authorize the Trustee to honor
telephone instructions for  the redemption  of Units  held in  book entry  form.
Units represented by Certificates may not be redeemed by telephone. The proceeds
of Units redeemed by telephone will be sent by check either to the Unitholder at
the  address specified on his account or to a financial institution specified by
the Unitholder for credit to the account of the Unitholder. A Unitholder wishing
to  use  this  method  of  redemption  must  complete  a  Telephone   Redemption
Authorization  Form and  furnish the Form  to the  Trustee. Telephone Redemption
Authorization  Forms   can   be   obtained  from   a   Unitholder's   registered
representative  or by calling the  Trustee. Once the completed  Form is on file,
the Trustee  will honor  telephone redemption  requests by  any person.  If  the
telephone  redemption request is  received prior to 4:00  p.m. eastern time, the
Unitholder will be  entitled to receive  for each Unit  tendered the  Redemption
Price  as determined above.  A telephone redemption  request received after 4:00
p.m. eastern time will be treated as having been received the following business
day. The redemption proceeds will be mailed within seven calendar days following
the telephone redemption  request. Telephone  redemptions are  limited to  1,000
Units  or less. Only  Units held in the  name of individuals  may be redeemed by
telephone; accounts registered in  broker name, or  accounts of corporations  or
fiduciaries   (including  among  others,   trustees,  guardians,  executors  and
administrators) may not use the telephone redemption privilege.
 
    On the seventh calendar day following the date of tender, or if the  seventh
calendar day is not a business day, on the first business day prior thereto, the
Unitholder  will be entitled to receive in cash for each Unit tendered an amount
equal to the Unit Value of such Trust determined by the Trustee, as of 4:00 p.m.
eastern time on the date of  tender as defined hereafter, plus accrued  interest
to,  but  not  including,  the  fifth business  day  after  the  date  of tender
("Redemption Price"). The  price received upon  redemption may be  more or  less
than  the amount paid by  the Unitholder depending on the  value of the Bonds on
the date of  tender. Such  value will vary  with market  and credit  conditions,
including  changes in  interest rate levels.  Unitholders should  check with the
Trustee or  their broker  to  determine the  Redemption Price  before  tendering
Units.
 
    While the Trustee has the power to determine Redemption Price when Units are
tendered,  the authority has by  practice been delegated by  the Trustee to John
Nuveen & Co.  Incorporated, which  determines the  Redemption Price  on a  daily
basis.
 
    The  "date of  tender" is  deemed to be  the date  on which  the request for
redemption of Units is received  in proper form by  the Trustee, except that  as
regards a redemption request
 
                                      A-30
<PAGE>
received  after 4:00 p.m. eastern time or on any day on which the New York Stock
Exchange (the "Exchange") is normally closed, the date of tender is the next day
on which such Exchange  is normally open  for trading and  such request will  be
deemed  to have been made on such day and the redemption will be effected at the
Redemption Price computed on that day.
 
    Accrued interest paid  on redemption  shall be withdrawn  from the  Interest
Account  of the  appropriate Trust or,  if the balance  therein is insufficient,
from the Principal Account of such  Trust. All other amounts paid on  redemption
shall  be withdrawn from the Principal Account. The Trustee is empowered to sell
underlying Bonds of  a Trust in  order to make  funds available for  redemption.
(See Section 21.) Units so redeemed shall be cancelled.
 
    To  the extent that Bonds  are sold from a Trust,  the size and diversity of
such Trust will  be reduced. Such  sales may be  required at a  time when  Bonds
would  not  otherwise  be sold  and  might  result in  lower  prices  than might
otherwise be realized.
 
    The Redemption Price is  determined on the  basis of the  BID prices of  the
Bonds  in each Trust, while  the initial Public Offering  Price of Units will be
determined on the  basis of the  OFFERING prices of  the Bonds as  of 4:00  p.m.
eastern  time on any day on which the  Exchange is normally open for trading and
such determination is made. As of any given time, the difference between the bid
and offering  prices of  such Bonds  may  be expected  to average  1% to  2%  of
principal  amount in the case of Bonds  in National, Long Intermediate and State
Trusts, 3/4%  to  1  1/2% in  the  case  of Bonds  in  Intermediate,  and  Short
Intermediate  Trusts and 1/2% to 3/4% in the case of Bonds in Short Term Trusts.
In the case of actively traded Bonds, the difference may be as little as 1/4  to
1/2  of 1%, and in  the case of inactively  traded Bonds such difference usually
will not exceed 3%. The difference between the aggregate offering prices of  the
Bonds  in each Trust  and the aggregate  bid prices thereof  on the business day
prior to  the Date  of Deposit  is shown  in the  discussion of  specific  trust
matters.
 
    The  right  of redemption  may be  suspended and  payment postponed  for any
period during  which  the Securities  and  Exchange Commission  determines  that
trading  in the municipal bond market is restricted or an emergency exists, as a
result  of  which  disposal  or  evaluation  of  the  Bonds  is  not  reasonably
practicable, or for such other periods as the Securities and Exchange Commission
may by order permit.
 
    Under  regulations issued by the Internal  Revenue Service, the Trustee will
be required to withhold 31% of the principal amount of a Unit redemption if  the
Trustee  has not  been furnished  the redeeming  Unitholder's tax identification
number in the  manner required by  such regulations. Any  amount so withheld  is
transmitted  to  the  Internal  Revenue  Service and  may  be  recovered  by the
Unitholder only when filing  his or her tax  return. Under normal  circumstances
the  Trustee obtains the Unitholder's tax identification number from the selling
broker at the time the Certificate or Book Entry Return Confirmation is  issued,
and  this number is printed on the Certificate or Book Entry Return Confirmation
and on distribution statements. If a Unitholder's tax identification number does
not appear as  described above,  or if it  is incorrect,  the Unitholder  should
contact  the Trustee before redeeming Units to determine what action, if any, is
required to avoid this "back-up withholding."
 
20.  HOW UNITS MAY BE PURCHASED BY THE SPONSOR
 
The Trustee will notify the  Sponsor of any tender  of Units for redemption.  If
the  Sponsor's bid in  the secondary market  at that time  equals or exceeds the
Redemption Price it may purchase such Units by notifying the Trustee before  the
close  of business on the  second succeeding business day  and by making payment
therefor to  the  Unitholder not  later  than the  day  on which  payment  would
otherwise have been made by the Trustee. (See Section 19.) The Sponsor's current
practice  is to bid at the Redemption  Price in the secondary market. Units held
by the Sponsor may be tendered to the Trustee for redemption as any other Units.
 
                                      A-31
<PAGE>
    The Public Offering  Price upon  resale of any  Units thus  acquired by  the
Sponsor  will be  calculated in accordance  with the procedure  described in the
then currently effective prospectus relating to such Units. Any profit resulting
from the resale of  such Units will  belong to the  Sponsor which likewise  will
bear  any loss resulting from a lower  Public Offering Price or Redemption Price
subsequent to its acquisition of such Units.
 
21.  HOW BONDS MAY BE REMOVED FROM THE TRUSTS
 
Bonds will be removed from a Trust as they mature or are redeemed by the issuers
thereof. See  the "Schedules  of Investments"  and "General  Trust  Information"
under Section 3 for a discussion of call provisions of portfolio Bonds.
 
    The  Indenture also empowers  the Trustee to  sell Bonds for  the purpose of
redeeming Units tendered by any Unitholder, and for the payment of expenses  for
which  income may not be available. Under the Indenture the Sponsor is obligated
to provide the Trustee with a current list of Bonds in each Trust to be sold  in
such  circumstances. In deciding which Bonds  should be sold the Sponsor intends
to consider, among  other things, such  factors as: (1)  market conditions;  (2)
market  prices  of  the  Bonds;  (3)  the  effect  on  income  distributions  to
Unitholders of the sale of various Bonds; (4) the effect on principal amount  of
underlying  Bonds  per Unit  of the  sale  of various  Bonds; (5)  the financial
condition of the issuers; and (6) the effect of the sale of various Bonds on the
investment character of the Trust. Such sales, if required, could result in  the
sale  of Bonds by the Trustee at prices less than original cost to the Trust. To
the extent Bonds are sold, the size and diversity of such Trust will be reduced.
 
    In addition, the  Sponsor is empowered  to direct the  Trustee to  liquidate
Bonds upon the happening of certain other events, such as default in the payment
of principal and/or interest, an action of the issuer that will adversely affect
its  ability to continue payment of the  principal of and interest on its Bonds,
or an  adverse  change  in  market, revenue  or  credit  factors  affecting  the
investment  character of the Bonds. If a default in the payment of the principal
of and/or interest  on any  of the  Bonds occurs, and  if the  Sponsor fails  to
instruct  the Trustee whether to  sell or continue to  hold such Bonds within 30
days after  notification by  the Trustee  to the  Sponsor of  such default,  the
Indenture  provides that  the Trustee shall  liquidate said  Bonds forthwith and
shall not be liable for any loss so incurred.
 
    In connection with its  determination as to the  sale or liquidation of  any
Bonds,  the Sponsor  will consider the  Bond's then current  rating, but because
such ratings are the opinions of the rating agencies as to the quality of  Bonds
they  undertake to rate and not absolute  standards of quality, the Sponsor will
exercise its independent judgment as to Bond creditworthiness.
 
    The Sponsor may also direct the Trustee to liquidate Bonds in a Trust if the
Bonds in  the  Trust  are  the  subject  of  an  advanced  refunding,  generally
considered  to be when refunding  bonds are issued and  the proceeds thereof are
deposited in irrevocable trust to retire the refunded Bonds on their  redemption
date.
 
    Except as stated in Section 4 regarding the limited right of substitution of
Replacement Bonds for Failed Bonds, and except for refunding securities that may
be  exchanged for Bonds under certain conditions specified in the Indenture, the
Indenture does  not permit  either the  Sponsor  or the  Trustee to  acquire  or
deposit  bonds either in addition  to, or in substitution  for, any of the Bonds
initially deposited in a Trust.

LIMITATIONS ON LIABILITIES OF SPONSOR AND TRUSTEE
 
    The  Sponsor and the Trustee shall be  under no liability to Unitholders for
taking any action or for  refraining from any action  in good faith pursuant  to
the Indenture, or for errors in judgment, but shall be liable only for their own
negligence,  lack of good faith or willful  misconduct. The Trustee shall not be
liable for depreciation or loss incurred by reason of the sale by the Trustee of
any of the Bonds. In the  event of the failure of  the Sponsor to act under  the
Indenture, the Trustee may act thereunder and shall not be liable for any action
taken by it in good faith under the Indenture.
 
    The  Trustee shall not be liable for any taxes or other governmental charges
imposed upon or in respect of the Bonds or upon the interest thereon or upon  it
as  Trustee under  the Indenture or  upon or in  respect of any  Trust which the
Trustee may be required  to pay under  any present or future  law of the  United
States  of  America or  of any  other taxing  authority having  jurisdiction. In
addition,  the  Indenture  contains  other  customary  provisions  limiting  the
liability of the Trustee.
 
SUCCESSOR TRUSTEES AND SPONSORS
 
    The  Trustee or any successor trustee  may resign by executing an instrument
of resignation in writing and filing same with the Sponsor and mailing a copy of
a notice of resignation to all  Unitholders then of record. Upon receiving  such
notice,  the Sponsor is required to promptly appoint a successor trustee. If the
Trustee becomes incapable of acting or is adjudged a bankrupt or insolvent, or a
receiver or other public officer shall  take charge of its property or  affairs,
the  Sponsor  may  remove  the  Trustee  and  appoint  a  successor  by  written
instrument. The resignation  or removal of  a trustee and  the appointment of  a
successor trustee shall become effective only when the successor trustee accepts
its appointment as such. Any successor trustee shall be a corporation authorized
to  exercise  corporate  trust  powers, having  capital,  surplus  and undivided
profits of not less than $5,000,000. Any corporation into which a trustee may be
merged or with which it may  be consolidated, or any corporation resulting  from
any  merger or consolidation to  which a trustee shall be  a party, shall be the
successor trustee.
 
    If upon resignation  of a trustee  no successor has  been appointed and  has
accepted the appointment within 30 days after notification, the retiring trustee
may  apply  to  a court  of  competent  jurisdiction for  the  appointment  of a
successor.
 
    If the Sponsor fails to undertake any of its duties under the Indenture, and
no express  provision is  made for  action by  the Trustee  in such  event,  the
Trustee  may, in addition to its other  powers under the Indenture (1) appoint a
successor sponsor or (2) terminate the Indenture and liquidate the Trusts.

24.  OTHER INFORMATION
AMENDMENT OF INDENTURE
 
    The Indenture may  be amended  by the Trustee  and the  Sponsor without  the
consent  of any of  the Unitholders (1) to  cure any ambiguity  or to correct or
supplement any provision thereof which may be defective or inconsistent, or  (2)
to  make such  other provisions as  shall not adversely  affect the Unitholders,
provided, however, that the Indenture may not be amended to increase the  number
of Units in any Trust or to permit the deposit or acquisition of bonds either in
addition  to, or in substitution for any of the Bonds initially deposited in any
Trust except as stated in Section 4 regarding the limited right of  substitution
of  Replacement Bonds and  except for the substitution  of refunding bonds under
certain circumstances. The Trustee shall advise the Unitholders of any amendment
promptly after execution thereof.
 
TERMINATION OF INDENTURE
 
    Each Trust may be liquidated at any  time by written consent of 100% of  the
Unitholders  or by  the Trustee when  the value of  such Trust, as  shown by any
semi-annual evaluation, is  less than 20%  of the original  principal amount  of
such Trust and will be liquidated by the Trustee in the event that Units not yet
sold  aggregating more than 60% of the Units originally created are tendered for
redemption by the Sponsor thereby reducing the  net worth of such Trust to  less
than  40%  of the  principal amount  of  the Bonds  originally deposited  in the
portfolio. (See "Essential Information Regarding the Trusts.") The sale of Bonds
from the Trusts upon  termination may result in  realization of a lesser  amount
than  might otherwise be realized  if such sale were  not required at such time.
For this  reason,  among  others,  the amount  realized  by  a  Unitholder  upon
termination   may  be  less  than  the  principal  amount  of  Bonds  originally
represented by the Units held by  such Unitholder. The Indenture will  terminate
upon the redemption, sale or other disposition of the last Bond held thereunder,
but  in no event shall it continue beyond the end of the calendar year preceding
the fiftieth anniversary of its execution for National and State Trusts,  beyond
the  end  of  the  calendar  year preceding  the  twentieth  anniversary  of its
execution for Long Intermediate,  and Intermediate Trusts or  beyond the end  of
the  calendar year  preceding the tenth  anniversary of its  execution for Short
Intermediate and Short Term Trusts.
 
    Written notice of  any termination  specifying the  time or  times at  which
Unitholders  may surrender their Certificates, if any, for cancellation shall be
given by  the  Trustee  to each  Unitholder  at  the address  appearing  on  the
registration  books of the Trust maintained  by the Trustee. Within a reasonable
time thereafter the Trustee shall liquidate any Bonds in the Trust then held and
shall deduct  from  the assets  of  the Trust  any  accrued costs,  expenses  or
 
                                      A-35
<PAGE>
indemnities  provided  by  the  Indenture which  are  allocable  to  such Trust,
including estimated compensation of the Trustee and costs of liquidation and any
amounts required as a reserve to provide for payment of any applicable taxes  or
other  governmental charges. The Trustee shall then distribute to Unitholders of
such Trust their pro  rata share of  the balance of  the Interest and  Principal
Accounts.  With such  distribution the  Unitholders shall  be furnished  a final
distribution  statement,  in   substantially  the  same   form  as  the   annual
distribution statement, of the amount distributable. At such time as the Trustee
in  its sole discretion shall determine that  any amounts held in reserve are no
longer necessary, it shall make distribution thereof to Unitholders in the  same
manner.

                            DESCRIPTION OF RATINGS*
 
    STANDARD & POOR'S CORPORATION.  A  description of the applicable Standard  &
Poor's Corporation rating symbols and their meanings follows:
 
    A  Standard & Poor's rating is  a current assessment of the creditworthiness
of an obligor with  respect to a specific  debt obligation. This assessment  may
take into consideration obligors such as guarantors, insurers or lessees.
 
    The  rating is not  a recommendation to  purchase, sell or  hold a security,
inasmuch as  it  does not  comment  as to  market  price or  suitability  for  a
particular investor.
 
    The  ratings are  based on  current information  furnished by  the issuer or
obtained by Standard & Poor's from other sources it considers reliable. Standard
& Poor's does not  perform an audit  in connection with any  rating and may,  on
occasion,  rely on unaudited financial information.  The ratings may be changed,
suspended or withdrawn  as a result  of changes in,  or unavailability of,  such
information, or for other circumstances.
 
    The ratings are based, in varying degrees, on the following considerations:
 
     I.  Likelihood  of default--capacity and  willingness of the  obligor as to
         the timely payment of interest and repayment of principal in accordance
         with the terms of the obligation;
 
     II.  Nature of and provisions of the obligation;
 
    III.  Protection afforded by,  and relative position  of, the obligation  in
          the  event of  bankruptcy, reorganization or  other arrangements under
          the laws of bankruptcy and other laws affecting creditors' rights.
 
    AAA--This is the  highest rating  assigned by Standard  & Poor's  to a  debt
obligation. Capacity to pay interest and repay principal is extremely strong.
 
    AA--Bonds  rated AA have  a very strong  capacity to pay  interest and repay
principal, and differ from the highest rated issues only in small degree.
 
    A--Bonds rated A have a strong capacity to pay interest and repay principal,
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than bonds in higher rated categories.
 
    BBB--Bonds rated BBB  are regarded  as having  an adequate  capacity to  pay
interest  and repay principal. Whereas they normally exhibit adequate protection
parameters, adverse  economic  conditions  or changing  circumstances  are  more
likely  to lead to a  weakened capacity to pay  interest and repay principal for
bonds in this category than for bonds in the higher rated categories.
 
    Plus (+) or Minus (-): The ratings from "AA" to "BB" may be modified by  the
addition  of a  plus or minus  sign to  show relative standing  within the major
rating categories.
 
    Provisional  Ratings:  The   letter  "p"  indicates   that  the  rating   is
provisional.  A  provisional rating  assumes  the successful  completion  of the
project being financed by  the issuance of the  bonds being rated and  indicates
that  payment of debt service requirements is largely or entirely dependent upon
the successful and timely completion of the project. This rating, however, while
addressing credit  quality subsequent  to completion  of the  project, makes  no
comment  on the  likelihood of,  or the  risk of  default upon  failure of, such
completion. Accordingly,  the investor  should exercise  his own  judgment  with
respect to such likelihood and risk.

*As published by the rating companies.
 
                                      A-37
<PAGE>
    Note  Ratings:  A  Standard  & Poor's  note  rating  reflects  the liquidity
concerns and market access risks unique to  notes. Notes due in 3 years or  less
will  likely receive  a note  rating. Notes  maturing beyond  3 years  will most
likely receive a long-term debt rating.
 
    Note rating symbols are as follows:
 
        SP-1  Very strong  or strong  capacity to  pay principal  and  interest.
              Those   issues   determined   to   possess   overwhelming   safety
              characteristics will be given a plus (+) designation.
 
        SP-2  Satisfactory capacity to pay principal and interest.
 
RATINGS OF INSURED TRUST UNITS.
 
    A Standard  &  Poor's  Corporation's  rating on  the  units  of  an  insured
investment  trust (hereinafter referred to collectively as "units" and "trusts")
is a current assessment of creditworthiness with respect to the investment  held
by  such trust. This assessment takes  into consideration the financial capacity
of the  issuers and  of any  guarantors, insurers,  lessees or  mortgagors  with
respect to such investments. The assessment, however, does not take into account
the  extent to which trust  expenses or portfolio asset  sales for less than the
trust purchase price will reduce payment  to the unitholder of the interest  and
principal  required to be paid on the  portfolio assets. In addition, the rating
is not a recommendation to purchase, sell or hold units, inasmuch as the  rating
does not comment as to market price of the units or suitability for a particular
investor.
 
    Units rated "AAA" are composed exclusively of assets that are rated "AAA" by
Standard  &  Poor's and/or  certain  short-term investments.  Standard  & Poor's
defines its  AAA  rating for  such  assets as  the  highest rating  assigned  by
Standard  & Poor's  to a  debt obligation.  Capacity to  pay interest  and repay
principal is very strong.  However, unit ratings may  be subject to revision  or
withdrawal  at any time by Standard & Poor's and each rating should be evaluated
independently of any other rating.
 
    MOODY'S INVESTORS  SERVICE, INC.    A brief  description of  the  applicable
Moody's Investors Service, Inc. rating symbols and their meanings follows:
 
    Aaa--Bonds which are rated Aaa are judged to be the best quality. They carry
the  smallest degree of investment  risk and are generally  referred to as "gilt
edge." Interest payments are protected by a large or by an exceptionally  stable
margin and principal is secure. While the various protective elements are likely
to  change, such changes  as can be  visualized are most  unlikely to impair the
fundamentally strong position of such issues. Their safety is so absolute  that,
with  the  occasional  exception  of oversupply  in  a  few  specific instances,
characteristically, their  market  value  is affected  solely  by  money  market
fluctuations.
 
    Aa--Bonds  which  are rated  Aa  are judged  to be  of  high quality  by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are  rated lower than the  best bonds because margins  of
protection  may  not  be  as  large as  in  Aaa  securities  or  fluctuations of
protective elements may be of greater  amplitude or there may be other  elements
present  which  make the  long-term  risks appear  somewhat  larger than  in Aaa
securities. Their  market value  is virtually  immune to  all but  money  market
influences,  with  the  occasional exception  of  oversupply in  a  few specific
instances.
 
    A--Bonds which are rated A possess many favorable investment attributes  and
are  to be considered as upper medium grade obligations. Factors giving security
to principal and interest are considered  adequate, but elements may be  present
which  suggest a susceptibility to impairment sometime in the future. The market
value of A-rated bonds may be
 
                                      A-38
<PAGE>
influenced to some degree by economic  performance during a sustained period  of
depressed  business conditions, but,  during periods of  normalcy, A-rated bonds
frequently move in  parallel with Aaa  and Aa obligations,  with the  occasional
exception of oversupply in a few specific instances.
 
    Moody's  bond rating  symbols may contain  numerical modifiers  of a generic
rating classification. The modifier 1 indicates that the bond ranks at the  high
end  of its  category; the  modifier 2  indicates a  mid-range ranking;  and the
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
 
    Baa--Bonds which are rated Baa  are considered as medium grade  obligations,
i.e.,  they are neither  highly protected nor  poorly secured. Interest payments
and principal security appear  adequate for the  present but certain  protective
elements  may be lacking or may  be characteristically unreliable over any great
length of time. Such  bonds lack outstanding  investment characteristics and  in
fact  have speculative  characteristics as well.  The market  value of Baa-rated
bonds is more  sensitive to changes  in economic circumstances,  and aside  from
occasional  speculative factors applying to some bonds of this class, Baa market
valuations move in  parallel with Aaa,  Aa and A  obligations during periods  of
economic normalcy, except in instances of oversupply.
 
    Con.  (--)--Bonds for which the security depends upon the completion of some
act or the  fulfillment of  some condition  are rated  conditionally. These  are
bonds  secured by (a)  earnings of projects under  construction, (b) earnings of
projects unseasoned  in  operation  experience, (c)  rentals  which  begin  when
facilities are completed, or (d) payments to which some other limiting condition
attaches.  Parenthetical rating denotes probable  credit stature upon completion
of construction or elimination of basis of condition.
 
    Note Ratings:
 
    MIG 1--This designation  denotes  best  quality.  There  is  present  strong
           protection  by established cash flows,  superior liquidity support or
           demonstrated broad-based access to the market for refinancing.
 
    MIG 2--This designation  denotes high  quality.  Margins of  protection  are
           ample although not so large as in the preceding group.

John Nuveen & Co. Incorporated

Chicago, Illinois  60606
RE:  Nuveen Tax-Exempt Unit Trust, Series 711

Gentlemen:

    We have served as counsel for you, as Depositor of Nuveen Tax-Exempt Unit
Trust, Series 711 (the "Fund") in connection with the issuance under the
Trust Indenture and Agreement, dated the date hereof between John Nuveen & Co.
Incorporated, as Depositor, and United States Trust Company of New York, as
Trustee, of Units of fractional undivided interest (the "Units"), as evidenced
by a certificate or book entry position, in the one or more Trusts of said
Fund.

    We have also served as counsel for you in connection with all previous
Series of the Nuveen Tax-Exempt Unit Trust and as such have previously 
examined such pertinent records and documents and matters of law as we have 
deemed necessary, including (but not limited to) the Trust Indenture and 
Agreements with respect to those series.  We have also examined such 
pertinent records and documents and matters of law as we have deemed 
necessary including (but not limited to) the Trust Indenture and Agreement 
relating to Nuveen Tax-Exempt Unit Trust, Series 711.

    We have concluded that the Trust Indenture and Agreement for the Fund and
its counterpart in each of the prior issues of Nuveen Tax-Exempt Unit Trust 
are in all material respects substantially identical.

    Based upon the foregoing, and upon such matters of law as we consider
to be applicable we are of the opinion that, under existing federal income
law:

    (i)  For Federal income tax purposes, each of the Trusts will not be
taxable as an association but will be governed by the provisions of 
Subchapter J (relating to Trusts) of Chapter 1, Internal Revenue Code of 
1986 (the "Code").

    (ii) Each Unitholder will be considered as owning a pro rata
share of each asset of the respective Trust of the Fund in the proportion
that the number of Units of such Trust held by him bears to the total number
of outstanding Units of such Trust. Under Subpart E, Subchapter J of Chapter
1 of the Code, income of each Trust will be treated as income of each
Unitholder thereof in the proportion described and an item of Fund income
will have the same character in the hands of a Unitholder as it would have in
the hands of the Trustee.  Accordingly, to the extent that the income of a
Trust consists of interest and original issue discount excludable from gross
income under Section 103 of the Code, such income will be excludable from
federal gross income of the Unitholder, except in the case of a Unitholder
who is a substantial user (or a person related to such user) of a facility
financed through issuance of any industrial development bonds or certain
private activity bonds held by the Trust. In the case of such Unitholder who
is a substantial user (and no other) interest received and original issue
discount with respect to his Units attributable to such industrial
development bonds or such private activity bonds is includable in his gross
income. In the case of certain corporations, interest on the Bonds is included
in computing the alternative minimum tax pursuant to Sections 56(f) and 56(g)
of the Code, the enviromental tax (the "Superfund Tax") imposed by Sections
59A of the Code, and the branch profits tax imposed by Section 884 of the Code
with repect to U.S. branches of foreign corporations.

    (iii) Gain or loss will be recognized to a Unitholder upon
redemption or sale of his Units.  Such gain or loss is measured by comparing 
the proceeds of such redemption or sale with the adjusted basis of such Units.
Before adjustment, such basis would normally be cost if the Unitholder had
acquired his Units by purchase, plus his aliquot share of advances by the
Trustee to the Trust to pay interest on Bonds delivered after the Unitholder's
settlement date to the extent that such interest accrued on the Bonds during
the period from the Unitholder's settlement date to the date such Bonds are
delivered to the Trust, but only to the extent that such advances are to be
repaid to the Trustee out of interest received by the Fund with respect to
such Bonds.  In addition, such basis will be increased by both the
Unitholder's aliquot share of the accrued original issued discount with
respect to each Bond held by the Trust with respect to which there was an
original issue discount and reduced by the annual amortization of bond
premium, if any, on Bonds held by the Trust.

<PAGE>

    (iv) If the Trustee disposes of a Trust asset (whether by sale, payment on
maturity, redemption or otherwise), gain or loss is recognized to the
Unitholder and the amount thereof is measured by comparing the
Unitholder's aliquot share of the total proceeds from the transaction
with his basis for his fractional interest in the asset disposed of.  Such 
basis is ascertained by apportioning the tax basis for his Units among each 
of the Trust assets (as of the date on which his Units were acquired) ratably 
according to their values as of the valuation date nearest the date on which 
he purchased such Units.  A Unitholder's basis in his Units and of his
fractional interest in each Trust asset must be reduced by the amount of his 
aliquot share of interest received by the Fund, if any, on Bonds delivered
after the Unitholder's settlement date to the extent that such
interest accrued on the Bonds during the period from the Unitholder's
settlement date to the date such Bonds are delivered to the Trust, must be 
reduced by the annual amortization of bond premium, if any, on Bonds held by 
the Trust and must be increased by the Unitholder's share of accrued
original issue discount with respect to each Bond which, at the time
the Bond was issued, had original issue discount.

     (v)  In the case of any Bond held by the Trust where the "stated
redemption price at maturity" exceeds the "issue price," such excess shall
be original issue discount.  With respect to each Unitholder, upon the
purchase of his Units subsequent to the original issuance of Bonds held by the
Trust Section 1272(a)(7) of the Code provides for a reduction in the accrued
"daily portion" of such original issue discount upon the purchase of a Bond
subsequent to the Bond's original issue, under certain circumstances.  In the
case of any Bond held by the Trust the interest on which is excludable from
gross income under Section 103 of the Code, any original issue discount which
accrues with respect thereto will be treated as interest which is excludable
from gross income under Section 103 of the Code.

    (vi)  In the case of any Bond which matures within one year of the date
issued, the accrual of tax-exempt original issue discount will generally be
computed daily on a ratable basis unless the Unitholder elects to accrue such
discount under a constant yield method, compounded daily.

    (vii)  In the case of any Bond which does not mature within one year
after the date issued, tax-exempt original issue discount will accrue
daily, computed generally under a constant yield method, compounded
semiannually (with straight line interpolation between compounding dates).

    (viii)  In the case of Trusts for which Municipal Bond Investors Assurance
Corporation ("MBIA") insurance with respect to each of the Bonds deposited
therein has been obtained by the Depositor or the issuer or underwriter of the
Bonds, we have examined the form of MBIA's policy or several policies of
insurance (the "Policies") which have been delivered to the Trustee.  Assuming
issuance of Policies in such form, in our opinion, any amounts paid under said
Policies representing maturing interest on defaulted obligations held by the
Trustee will be excludable from Federal gross income if, and to the same
extent as, such interest would have been so excludable if paid by the
respective issuer.  Paragraph (ii) of this opinion is accordingly applicable
to Policy proceeds representing maturing interest.
<PAGE>

    Because the Trusts do not include any "specified private activity bonds"
within the meaning of Section 57(a)(5) of the Code issued on or after August
8, 1986, none of the Trust Fund's interest income shall be treated as an item
of tax preference when computing the alternative minimum tax.  In the case of
corporations, for taxable years beginning after December 31, 1986, the alter-
native minimum tax and the Superfund Tax depend upon the corporation's
alternative minimum taxable income ("AMTI"), which is the corporation's
taxable income with certain adjustments.

    Pursuant to Section 56(f) of the Code, one of the adjustment
items used in computing AMTI and the Superfund Tax of a corporation
(other than an S Corporation, Regulated Investment Company, Real Estate
Investment Trust or REMIC) is an amount equal to 50% of the excess of such
corporation's "adjusted net book income" over an amount equal to its AMTI
(before such adjustment item and the alternative tax net operating
loss deduction).  For taxable years beginning after 1989, such adjustment item
will be 75% of the excess of such corporation's "adjusted current earnings"
over an amount equal to its AMTI (before such adjustment item and the
alternative tax net operating net operating loss deduction) pursuant to
Section 56(g) of the Code.  Both "adjusted net book income" and "adjusted
current earnings" include all tax-exempt interest, including interest on all
Bonds in the Trust, and tax-exempt original issue discount.

   Effective for tax returns filed after December 31, 1987,  all taxpayers
are required to disclose to the Internal Revenue Service the amount of
tax-exempt interest earned during the year.

    Section 265 of the Code generally provides for a reduction
in each taxable year of 100% of the otherwise deductible interest on
indebtedness incurred or continued by financial institutions, to which either 
Section 585 or Section 593 of the Code applies, to purchase or carry 
obligations acquired after August 7, 1986, the interest on which is exempt
from federal income taxes for such taxable year.  Under rules prescribed by 
Section 265, the amount of interest otherwise deductible by such financial
institutions in any taxable year which is deemed to be attributable to 
tax-exempt obligations acquired after August 7, 1986 will be the amount
that bears the same ratio to the interest deduction otherwise allowable
(determined without regard to Section 265) to the taxpayer for the taxable
year as the taxpayer's average adjusted basis (within the meaning of Section
1016) of tax-exempt obligations acquired after August 7, 1986, bears to
such average adjusted basis for all assets of the taxpayer, unless such 
financial institution can otherwise establish under regulations to be
prescribed by the Secretary of the Treasury, the amount of interest on 
indebtedness incurred or continued to purchase or carry such obligations.

<PAGE>

    We also call attention to the fact that, under Section 265 of the
Code,  interest on indebtedness incurred or continued to purchase or carry
Units by taxpayers other than certain financial institutions, as referred to
above, is not deductible for Federal income tax purposes. Under rules used by
the Internal Revenue Service for determining when borrowed funds are con-
sidered used for the purpose of purchasing or carrying particular assets, the
purchase of Units may be considered to have been made with borrowed funds even
though the borrowed funds are not directly traceable to the purchase of Units.
However, these rules generally do not apply to interest paid on indebtedness
incurred for expenditures of a personal nature such as a mortgage incurred to
purchase or improve a personal residence.

    "The Revenue Reconciliation Act of 1993" (the "Tax Act") subjects 
tax-exempt bonds to the market discount rules of the Code effective for 
bonds purchased after April 30, 1993.  In general, market discount is the 
amount (if any) by which the stated redemption price at maturity exceeds 
an investor's purchase price (except to the extent that such difference, 
if any, is attributable to original issue discount not yet accrued).  
Market discount can arise based on the price a Trust pays for Bonds
or the price a Unitholder pays for his or her Units.  Under the Tax Act,
accretion of market discount is taxable as ordinary income; under prior law,
the accretion had been treated as capital gain.  Market discount that accretes
while a Trust holds a Bond would be recognized as ordinary income by the
Unitholders when principal payments are received on the Bond, upon sale or at 
redemption (including early redemption), or upon the sale or redemption of his
or her Units, unless a Unitholder elects to include market discount in taxable
income as it accrues.
     
    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-51205) relating to the Units referred
to above and to the use of our name and to the reference to our firm in said
Registration Statement and in the related Prospectus.

         California Insured Trust 219  
            
                  

Dear Sirs:

        We have acted as special California counsel for John Nuveen & Co.
Incorporated, as Depositor of the above captioned trust(s) (each a "Trust"),
in connection with the issuance under the Trust Agreement dated 01/06/94,
among John Nuveen & Co. Incorporated, as Depositor, and United States Trust
Company of New York, as Trustee, of units of fractional undivided
interest in each Trust (the "Units") in exchange for certain bonds, as well as
"regular-way" and "when-issued" contracts for the purchase of bonds (such
bonds and contracts are hereinafter referred to collectively as the
Securities").

        In connection therewith, we have examined such corporate records,
certificates and other documents and such questions of law as we have deemed
necessary or appropriate for the purpose of this opinion, and, on the basis
of such examination, and upon existing provisions of the Revenue and Taxation
Code of the State of California, with respect to each Trust, we are of the
opinion that:

        1.  The Trust is not an association taxable as a corporation
and the income of the Trust will be treated as the income of the unitholders
under the income tax laws of California.

        2.  Interest on the underlying Securities (which may include bonds
or other obligations issued by the governments of Puerto Rico, the Virgin
Islands, Guam, or the Northern Mariana Islands) which is exempt from tax
under California personal income tax and property tax laws when received by
the Trust will, under such laws, retain its status as tax-exempt interest when
distributed to unitholders.  However, interest on the underlying securities
attributed to a unitholder which is a corporation subject to the California
franchise tax laws may be includable in such corporation's gross income for
purposes of determining its California franchise tax.

        3.  Under California income tax law, each unitholder in the Trust will
have a taxable event when the Trust disposes of a security (whether by sale,
exchange, redemption, or payment at maturity) or when the unitholder redeems
or sells Units.  Because of the requirement that tax cost basis be reduced to
reflect amortization of bond premium, under some circumstances a
unitholder may realize taxable gain when units are sold or
redeemed for an amount equal to, or less than, their original cost.
The total tax cost of each Unit to a unitholder is allocated among each of
the bond issues held in the Trust (in accordance with the proportion of the
Trust comprised by each bond issue) in order to determine his per unit tax
cost for each bond issue; and the tax cost reduction requirements relating to
amortization of bond premium will apply separately to the per unit cost of
each bond issue.  Unitholders' bases in their Units, and the bases for
their fractional interest in each Trust asset, may have to be adjusted for
their pro rata share of accrued interest received, if any, on securities
delivered after the unitholders' respective settlement dates.

        4.  Under the California personal property tax laws, bonds (including
the Securities) or any interest therein is exempt from such tax.

        5.  Proceeds paid under an insurance policy, if any, issued to the
Trustee of the Trust with respect to the Securities which represent maturing
interest on defaulted obligations held by the Trustee will be exempt from
California personal income tax if, and to the same extent as, such interest
would have been so exempt if paid by the issuer of the defaulted obligations.

<PAGE> 

        6.  Under Section 17280(b)(2) of the California Revenue and
Taxation Code, interest on indebtedness incurred or continued to purchase
or carry Units of the Trust is not deductible for the purposes of the
California personal income tax.  While there presently is no California
authority interpreting this provision, Section 17280(b)(2) directs the
California Francise Tax Board to prescribe regulations determining the
proper allocation and apportionment of interest costs for this purpose.
The Franchise Tax Board has not yet proposed or prescribed such regulations.
In interpreting the generally similar Federal provision, the Internal
Revenue Service has taken the position that such indebtedness need not be
directly traceable to the purchase or carrying of Units (although the Service
has not contended that a deduction for interest on indebtedness incurred
to purchase or improve a personal residence or to purchase goods or services
for personal consumption will be disallowed).  In the absence of conflicting
regulations or other California authority, the California Franchise Tax
Board generally has interpreted California statutory tax provisions in accord
with Internal Revenue Service interpretations of similar Federal provisions.


       Opinions relating to the validity of securities and the exemption of
interest thereon from State of California income tax are rendered by bond
counsel to the issuing authority at the time securities are issued and we
have relied solely upon such opinions, or, as to securities not yet
delivered, forms of such opinions contained in official statements
relating to such securities.  Except in certain instances in which we acted
as bond counsel to issuers of securities, and as such made a review of pro-
ceedings relating to the issuance of certain securities at the time of their
issuance, we have not made any review of proceedings relating to the issuance
of securities or the bases of bond counsels' opinions.

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-51205) relating to the Units referred to
above and to the use of our name and to the reference to our firm in said
Registration Statement and in the related Prospectus.

Very truly yours,

Nuveen Tax-Exempt Unit Trust, Series 711
Florida Insured Trust 184
John Nuveen & Co. Incorporated
333 W. Wacker Drive
Chicago, Illinois  60606

Attn:  James J. Wesolowski, Esquire
       Vice President, General Counsel
       and Secretary

        Re:   
             Florida Insured Trust 184

Gentlemen:

    We have acted as special Florida counsel to Nuveen Tax-Exempt Unit Trust,
- - including the above-captioned trust (the "Fund") in connection with the
issuance by the Fund of units of fractional undivided interests in the Fund
(the "Units").  In that connection, you have requested our opinion as to the
application of Florida state and local taxes to the Trust (as hereinafter
defined) and to investors who purchase units in the Trust.

    We have not been furnished with a copy of the Registration Statement or 
the prospectus, which is a part of the Registration Statement relating to the
issuance by the Fund of the Units.  However, you have authorized us to assume
that the proposed offer and sale of the Units, including the units of the
Florida Trust, will be carried out in that same manner and upon the same terms
and conditions as those described in any prospectus for a previous Nuveen
Tax-Exempt Unit Trust that contained a Florida Insured Trust.
In addition, you have authorized us to assume and we have assumed that:

    (a)  The Fund has been organized under a Trust Indenture and Agreement
between John Nuveen & Co., Incorporated (the "Depositor") and United States
Trust Company of New York (the "Trustee").

    (b)  The Fund will issue the Units in several State Trusts; one of which
is the Florida Insured Trust (the "Trust").

    (c)  The Units will be purchased by various investors who may be 
individuals or corporations.

    (d)  Each Unit of the Trust represents a fractional undivided interest in
the principal and net income of the Trust in the ratio of ten Units for each
$1,000 principal amount of the obligations initially acquired by the Trust.

    (e)  Each Trust will be administered as a distinct entity with separate
certificates, investments, expenses, books, and records.

    (f)  The assets of the Trust will consist solely of interest-bearing
obligations issued by or on behalf of the State of Florida, its political
subdivisions, and authorities or by the Commonwealth of Puerto Rico, Guam
or the Virgin Islands.

    (g)  Distributions of interest received by the Trust will be made
semi-annually, unless the Unitholder elects otherwise.

    (h)  The interest on all Bonds in the Trust will be exempt from Federal
income tax.(N.1)

    (i)  The Bonds have been issued in strict compliance with all requirements
of Florida, Federal or territorial law.

    (j)  The Fund is a registered investment company under the Investment
Company Act of 1940, as amended.


    In rendering our opinion, you have advised us that Messrs. Chapman and
Cutler have rendered the following opinions and have authorized us to rely 
upon such opinions and we have relied upon such opinions that:

    (a)  The Trust will not be taxable as an association but will be governed 
by the provisions of Subchapter J (relating to trusts) of Chapter 1 of the 
Internal Revenue Code of 1986, as amended.

    (b)  Each Unitholder will be considered as owning a pro-rata share
of each asset of the Trust to which such Unit relates in the proportion
that the number of Units of the Trust held by him bears to the total number of
outstanding Units of the Trust and will be subject to Federal income tax on
the income therefrom under the provisions of Subpart E of Subchapter J of
Chapter 1 of the Internal Revenue Code of 1986, as amended.

    (c)  The Trust will not be subject to Federal income taxes.

<PAGE>

    (d)  For Federal income tax purposes, each item of Trust income will have
the same character in the hands of a Unitholder as it would have in the
hands of the Trustee.  Accordingly, to the extent that the income of the Trust
consists of interest excludable from Federal gross income under Section 103 of
the Internal Revenue Code of 1986, as amended, such income will be excludable
from Federal gross income of the Unitholders.

    (e)  For Federal income tax purposes, each Unitholder will have a
taxable event when, upon redemption or sale of his Units, he receives 
cash or other property.  Gain or loss will be measured by comparing the
proceeds of such a redemption or sale with the Unitholder's adjusted
basis for the Unit.  Before adjustment, generally this basis would be cost, if
the Unitholder had purchased his Units, plus his share of certain
advances by the Trustee to the Trust and certain accrued original issue
discount.  For Federal income tax purposes, if the Trustee disposes of a Trust
asset (whether by sale, payment on maturity, retirement, or otherwise), gain
or loss will be recognized by each Unitholder, and such gain or loss is
computed by measuring the Unitholder's aliquot share of the total
proceeds from the transaction against his basis for his fractional interest in
the asset disposed of (such basis being determined by apportioning the basis
for his Units among all of the Trust's assets ratably according to their
values as of the valuation date nearest the date on which he purchased the
Units).  A Unitholder's basis in his Units and the basis for his
fractional interest in each Trust asset must be reduced by the amount of his
aliquot share of interest received, if any, on Bonds delivered after the
Unitholder's settlement date to the extent that such interest accrued
on the Bonds during the period from the Unitholder's settlement date to
the date such Bonds are delivered to the Trust and must be reduced annually by
amortization of premiums, if any, on obligations held by the Trust.
 
    For the purposes of this letter:

    (a)  "Florida Code" shall mean the Florida Income Tax Code, Chapter 220,
Florida Statutes (Supp. 1992), as amended by Chapter 93-172, laws  of Florida. 
In the Florida Income Tax Code, Chapter 220, Florida Statutes, the Florida 
Legistature has adopted, retroactively to January 1, 1993, the Internal 
Revenue Code of 1986, as amended and in effect on January 1, 1993, as the 
Internal Revenue Code under which a Corporate Unitholder must compute its 
income for purposes of Florida corporate income taxation.

    (b)  "Code" shall mean the Internal Revenue Code of 1986, as
amended and in effect on January 1, 1993.

    (c)  "Non-Corporate Unitholder" shall mean a Unitholder
of the Florida Trust who is an individual not subject to the income
tax on corporations imposed by the Florida Code.

    (d)  "Corporate Unitholder" shall mean a Unitholder of the
Florida Trust that is a corporation subject to the income tax on
corporations imposed by the Florida Code.

    (e)  "Nonbusiness Income" is defined in the Florida Code and shall mean
rents and royalties from real or tangible personal property, capital gains,
interest, dividends, and patent and copyright royalties, to the extent that
they do not arise from transactions and activities in the regular course of a
Corporate Unitholder's trade or business.  The term Nonbusiness Income
does not include income from tangible and intangible property if the
acquisition, management, and disposition of the property constitute integral
parts of a Corporate Unitholder's regular trade or business operations,
or any amounts which could be included in apportionable income without
violating the due process clause of the United States Constitution.  For
purposes of this definition, "income" means gross receipts less all expenses
directly or indirectly attributable thereto.

    (f)  "Commercial domicile" shall mean the place that a corporation
maintains its principal place of business.  The term "commercial domicile" is
not specifically defined in Florida law for Florida corporate income tax
purposes.  However, the Florida Supreme Court has on at least two occasions
attributed meaning to this phrase, and recently enacted legislation amending
how Florida's intangible personal property tax law defines this phrase.  The 
Court has implied that a corporation's commercial domicile is its principal 
place of business, Department of Revenue v. Amrep Corp., 358 So.2d 1343, 1350
(Fla. 1978).  The Court has also stated in another case that a particular
corporation's domicile was in New York City where its head office and the
actual seat of its over-all business government was located and from where
its executive officers regularly exercised their complete authority and
controlled and directed all activities of the corporation, wherever carried
on.  Gay v. Bessemer Properties, Inc., 32 So.2d 587, 591 (Fla. 1947).  In
recently enacted legislation, a corporation is considered to acquire a
commercial domicile in Florida "when it maintains its chief or principal
office in [Florida] where executive or management functions are performed
or where the course of business operations is determined."  Section 199.175
(1)(b), Florida Statutes (1989).

    Based solely upon the assumptions you have permitted us to make and the
opinions of Messrs. Chapman and Cutler upon which you have authorized us to
rely, we are of the opinion that:

    (a)  For Florida state income tax purposes, the Trust will not be subject 
to the income tax imposed by the Florida Code so long as the Trust has no
income subject to federal income taxation.  In addition, political sub-
divisions of Florida do not impose any income taxes.

    (b)  Because Florida does not impose an income tax on individuals,
Non-Corporate Unitholders will not be subject to any Florida income tax
on income realized by the Trust.  Each Corporate Unitholder will be
subject to Florida income taxation on its share of the income realized by the
Trust notwithstanding the tax exempt status of the interest received
from any bonds under Section 103(a) of the Code or any other federal law,
unless the interest income constitutes Nonbusiness Income.  Nevertheless,
any Corporate Unitholder that has its commercial domicile in Florida will be
taxable under the Florida Code on its share of the Trust income which
constitutes Nonbusiness Income.

<PAGE>

    (c)  A Non-Corporate Unitholder will not be subject to Florida
income taxation with respect to gain realized when Bonds held in the Trust 
are sold, redeemed, or paid at maturity.  A Corporate Unitholder will
be subject to Florida income taxation with respect to gain realized on such a 
sale, redemption, or payment at maturity of a Bond held by the Trust, except
to the extent that the gain realized therefrom constitutes Nonbusiness
Income.  Nevertheless, to the extent that gains realized by a Corporate
Unitholder arising from a sale, redemption, or payment at maturity
constitute Nonbusiness Income, such gain will be taxable under the Florida
Code if the Corporate Unitholder's commercial domicile is in Florida.

    (d)  Any gain realized by a Non-Corporate Unitholder from the
redemption, sale, or other disposition of a Unit will not be subject to 
Florida income tax.  Any gain realized by a Corporate Unitholder from
the redemption, sale, or other disposition of a Unit will be subject to 
Florida income tax except to the extent that the gain realized therefrom
constitutes Nonbusiness Income. Nevertheless, to the extent that gain
realized by a Corporate Unitholder arising from a sale, redemption, or
other disposition of a Unit consitutes Nonbusiness Income, such gain will be
taxable under the Florida Code if the Corporate Unitholder's commercial
domicile is in Florida.
 
    (e)  A Non-Corporate Unitholder will not be subject to Florida
income taxation with respect to amounts paid under the Municipal Bond
Investors Assurance Corporation insurance policies representing interest on
defaulted obligations held by the Trustee.  A Corporate Unitholder
will be subject to Florida income taxation on its share of amounts paid under 
the Municipal Bond Investors Assurance Corporation insurance policies
representing maturing interest on defaulted obligations held by the Trustee
except to the extent that such payments constitute Nonbusiness Income as de-
fined in the Florida Code.  Nevertheless, any Corporate Unitholder that
has its commercial domicile in Florida will be taxable under the Florida Code
on its share of amounts paid under the Municipal Bond Investors Assurance
Corporation insurance policies representing maturing interest on defaulted
obligations held by the Trustee even if such payments constitute Nonbusiness
Income.

    (f)  A Non-Corporate Unitholder will not be subject to Florida
income taxation with respect to gain realized with respect to amounts paid 
under the Municipal Bond Investors Assurance Corporation
insurance policies representing principal on defaulted
obligations held by the Trustee.  A Corporate Unitholder will be
subject to Florida income taxation with respect to gain realized on its share 
of amounts paid under the Municipal Bond Investors Assurance Corporation
insurance policies representing principal on defaulted obligations held by
the Trustee except to the extent that the gain realized constitutes
Nonbusiness Income.  Nevertheless, gain realized, by
any Corporate Unitholder that has its commercial domicile in Florida,
on such payments representing principal on defaulted obligations held by the
Trustee, will be taxable under the Florida Code even if such payments
constitute Nonbusiness Income.
 
    (g)  Even if interest on indebtedness incurred or continued by a
Unitholder to purchase Units in the Trust is not deductible for Federal
income tax purposes, under Code section 265(a)(2) or any other law,  it will
be deductible, in effect, by Corporate Unitholders for Florida income tax
purposes if interest earned on the Units is other than Nonbusiness Income.
Nevertheless, if interest earned on the Units is Nonbusiness Income, any
Corporate Unitholder that has its commercial domicile in Florida may reduce
the amount of interest included as Nonbusiness Income by the amount of
expenses directly or indirectly attributable thereto.

    (h)  Trust Units will be subject to Florida estate tax only if owned by
Florida residents and may be subjected to Florida estate tax if owned by other
decendents.  However, the Florida estate tax is limited to the amount of the
credit allowable under the applicable Federal Revenue Act (currently Section
2011 (and in some cases Section 2102) of the Internal Revenue Code of 1986,
as amended) for death taxes actually paid to the several states.

    (i)  Neither the Bonds nor the Units will be subject to the Florida ad
valorem tax or Florida sales or use tax.

    (j)  Because Bonds issued by the State of Florida, its political
subdivisions or by the Commonwealth of Puerto Rico, Guam, or the Virgin
Islands, are exempt from Florida intangible personal property taxation under
Chapter 199, Florida Statutes, the Trust will not be subject to Florida
intangible personal property tax.  In addition, the Unitholders will not be
subject to Florida intangible personal property tax on the Units.

    (k)  The sale, redemption, or other disposition by the Trust of Bonds
issued by the State of Florida, the Commonwealth of Puerto Rico, Guam, or the
Virgin Islands, will not subject either the Trust or the Unitholders to
Florida documentary stamp tax.

    (l)  The issuance and sale of the Units by the Trust will not
subject either the Trust or the Unitholders to Florida documentary
stamp tax.
 
    (m)  The transfer of Units by a Unitholder will not be
subject to Florida documentary stamp tax.

<PAGE>

    This opinion is limited to the law in effect as of the date hereof and
we assume no responsibility for changes in the law that may become effective
subsequent to the date of this opinion.  Furthermore, this letter is not to be
construed as a prediction of a favorable outcome with respect to any issue for
which no favorable prediction is made herein, or as a guaranty of any tax
result, or as offering an assurance or guaranty that a Florida state or local
taxing authority might not differ with our conclusions, or raise other
questions or issues upon audit, or that such action may not be judicially
sustained.

    We have not examined any of the Bonds to be deposited in the Fund and held
by the Trust, and we express no opinion as to whether the interest on any such
Bonds would, in fact, be tax-exempt if directly received by a 
Unitholder; nor have we made any review of the proceedings relating to
the issuance of the Bonds or the basis for the bond counsel opinions or the 
opinions of Messrs. Chapman and Cutler referred to herein.

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-51205) and to the reference to our
firm in such Registration Statement and the Prospectus included
therein. In giving such consent, we do not thereby admit that we are within 
the category of persons whose consent is required by Section 7 of the 
Securities Act of 1933, as amended, and the rules and regulations thereunder.

_______________________
(N.1) Section 2.01 of the Indenture provides that if the Depositor fails to
deposit Bonds, through no fault of its own, the Depositor may, as provided in
Section 3.14 of said Indenture, purchase replacement bonds (referred to as
"New Bonds") that will also be tax exempt bonds issued by the same states or 
their respective political subdivisions.


Very truly yours,

Nuveen Tax-Exempt Unit Trust,

In care of John Nuveen & Co.

333 West Wacker Drive
Chicago, IL  60606

Attention of James J. Wesolowski, Esq.
             Vice President, General Counsel
             and Secretary

United States Trust Company of New York,
as Trustee of Nuveen Tax-Exempt Unit Trust, Series 711

New York, NY  10003

                 Re:   
                      Massachusetts Insured Trust 109

Dear Sirs:

    We have acted as special counsel, with respect to Massachusetts State and
local tax matters, to the above mentioned Trust(s) ("Trust(s)") of Nuveen Tax-
Exempt Unit Trust, Series 711 (the "Fund") concerning a Registration
Statement (No. 33-51205) on Form S-6 under the Securities Act of 1933, as
amended (the "Registration Statement"), covering the issuance by the Fund
of Units of fractional undivided interest in the Fund.

    We have not been furnished with a copy of the Registration Statement or
the prospectus, which is a part of the Registration Statement, relating to the
issuance by the Fund of the Units.  However, John Nuveen & Co. Incorporated
has authorized us to assume that the proposed offer and sale of the Units will
be carried out in that same manner and upon the same terms and conditions as
that described in the prospectus for the Nuveen Tax-Exempt Unit Trust, Series
351 - Massachusetts Trust 182, dated November 6, 1985.

    We have been furnished with a copy of the opinion of Chapman and Cutler
on the federal tax status of the Fund, its constituent Trusts and their
Unitholders.

    In addition, we have also examined applicable Massachusetts law and a
ruling of the Massachusetts Department of Revenue dated February 7, 1985,
relating to Multi-State Series 162.

     Based on the foregoing it is our opinion that under existing law and
administration of the affairs of the Trust(s):

     A.  For Massachusetts income tax purposes, each Trust will be treated
         as a corporate trust under Section 8 of Chapter 62 of the
         Massachusetts General Laws ("M.G.L.") and not as a grantor trust
         under Section 10(e) of M.G.L. Chapter 62.

     B.  The Trust(s) will not be held to be engaging in business in
         Massachusetts within the meaning of said Section 8 and will,
         therefore, not be subject to Massachusetts income tax.
     C.  Unitholders who are subject to Massachusetts income taxation
         under M.G.L. Chapter 62 will not be required to include their
         respective shares of the earnings of or distributions from the
         Trust(s) in their Massachusetts gross income to the extent that such
         earnings or distributions represent tax-exempt interest excludable
         from gross income for federal income tax purposes received by the
         Trust(s) on obligations issued by Massachusetts, its counties,
         municipalities, authorities, political subdivisions or
         instrumentalities or by Puerto Rico, the Virgin Islands, Guam,
         the Northern Mariana Islands or other possessions of the United
         States within the meaning of Section 103(c) of the Internal Revenue
         Code of 1986, as amended ("Obligations").

     D.  In the case of a Massachusetts Insured Trust, Unitholders who are
         subject to Massachusetts income taxation under M.G.L. Chapter 62
         will not be required to include their respective shares of the
         earnings of or distributions from such Trust in their Massachsetts
         gross income to the extent that such earnings or distributions are
         derived from the proceeds of insurance obtained by the Sponsor of
         such Trust or by the issuer or underwriter of an obligation held
         by such Trust that represent maturing interest on defaulted
         obligations held by the Trustee, if and to the same extent that
         such earnings or distributions would have been excludable from the
         gross income of such Unitholders if derived from interest paid by
         the issuer of the defaulted obligation.

     E.  Unitholders which are corporations subject to taxation
         under M.G.L. Chapter 63 will be required to include their
         respective shares of the earnings of or distributions from the
         Trust(s) in their Massachusetts gross income to the extent that such
         earnings or distributions represent interest from bonds, notes or
         indebtedness of any state, including Massachusetts, except for
         interest which is specifically exempted from such tax by the acts
         authorizing issuance of said Obligations.

     F.  Each Trust's capital gains and/or capital losses which are includable
         in the federal gross income of Unitholders who are
         subject to Massachusetts income taxation under M.G.L. Chapter 62,
         or Unitholders which are corporations subject to
         Massachusetts taxation under M.G.L. Chapter 63 will be included as
         capital gains and/or losses in the Unitholders' Massachusetts
         gross income, except for capital gain which is specifically exempted
         from taxation under such Chapters by the acts authorizing issuance of
         said Obligations.

     G.  Unitholders which are corporations subject to tax under
         M.G.L. Chapter 63 and which are tangible property corporations will
         not be required to include the Units when determining the value
         of their tangible property; such Unitholders which are
         intangible property corporations will be required to include the
         Units when determining their net worth.

     H.  Gains or losses realized on sales or redemptions of Units by
         Unitholders who are subject to Massachusetts income taxation
         under M.G.L. Chapter 62 or Unitholders which are corporations
         subject to Massachusetts taxation under M.G.L. Chapter 63 will be
         includable in their Massachusetts gross income.  In determining such
         gain or loss Unitholders will, to the same extent required for
         Federal tax purposes, have to adjust their tax bases for their Units
         for accrued interest received, if any, on Obligations delivered to
         the Trustee after the Unitholders pay for their Units, for
         amortization of premiums, if any, on Obligations held by the
         Trust(s), and for accrued original issue discount with respect to
         each Obligation which, at the time the Obligation was issued, had
         original issue discount.

     I.  The Units of the Trust(s) are not subject to any property tax levied
         by Massachusetts or any political subdivision thereof, nor to any
         income tax levied by any such political subdivision.  They are
         includable in the gross estate of a deceased Unitholder who is a
         resident of Massachusetts for purposes of the Massachusetts Estate
         Tax.

     The foregoing opinions are based upon present provisions of federal and
Massachusetts law, administrative interpretations thereof and court decisions.
With respect to Unitholders which are corporations subject to

from the Trust(s) in their Massachusetts gross income to the extent that such
earnings or distributions represent interest from bonds, notes, or indebted-
ness of Puerto Rico, the Virgin Islands, Guam, the Northern Mariana Islands or
other possessions of the United States within the meaning of Section 103(c)

John Nuveen & Co. Incorporated
333 West Wacker Drive
Chicago, Illinois  60606

RE:  Nuveen Tax-Exempt Unit Trust, Series 711
      
     New Jersey Insured Trust 171

Gentlemen:

    We have acted as special counsel, with respect to New Jersey state tax
matters, to Nuveen Tax-Exempt Unit Trust, Series 711 (the "Fund")
concerning a Registration Statement (No. 33-51205) on Form S-6 under the
Securities Act of 1933, as amended, covering the issuance by the Fund of units
of fractional undivided interest (the "Units") in several state trusts (the
"State Trusts"), one of which is the above-captioned trust ("New
Jersey Trust").  Such Units will be purchased by various investors
("Unitholders").

     The Fund is organized under a Trust Indenture and Agreement (the
"Indenture") of even date herewith between John Nuveen & Co. Incorporated (the
"Depositor") and United States Trust Company of New York (the "Trustee").
Each Unit of the New Jersey Trust represents a fractional undivided interest
in the principal and net income of the New Jersey Trust in the ratio of ten
Units for each one thousand dollars ($1,000) of principal amount of the
obligations initially acquired by the New Jersey Trust.  The New Jersey Trust
will be administered as a distinct entity with separate certificates,
investments, expenses, books and records.

    In acting as special counsel, we have examined such documents and records
with respect to the immediately preceding series of Nuveen Tax-Exempt Unit
Trust - Series which included a State Trust consisting primarily of Bonds
(herein defined) (the "Prior Series") as we deem necessary, including, but not
limited to, the Trust Indenture and Agreement (the "Prior Series Indenture")
and the Prospectus.  You have advised that the Indenture is identical in all
material respects to the Prior Series Indenture.  You have also advised that
the opinion of Messrs. Chapman and Cutler with respect to the Federal income
tax status of the Fund, its constituent State Trusts and its Unitholders is
in all material respects identical to the opinion issued by Messrs. Chapman
and Cutler for the Prior Series.

    We note that the assets of the New Jersey Trust will consist of
interest-bearing obligations issued by or on behalf of the State of New
Jersey, and counties, municipalities, authorities and other political
subdivisions thereof, and certain territories of the United States including
Puerto Rico, Guam, the Virgin Islands and the Northern Mariana Islands (the
"Bonds").  Distributions of the interest received by the New Jersey Trust will
be made to each Unitholder semi-annually unless the Unitholder elects to
receive such distributions on a monthly or quarterly basis.  In the
opinion of bond counsel to each issuer, the interest on all Bonds in the New
Jersey Trust is exempt from Federal income tax under existing law.

    We understand that on this date (the "Date of Deposit") the Depositor has
deposited with the Trustee the total principal amount of interest-bearing
obligations and/or contracts for the purchase thereof together with an
irrevocable letter of credit in the amount required for the purchase price and
accrued interest, if any, and an insurance policy or policies purchased by the
Depositor and issued by the Municipal Bond Investors Assurance Corporation
(the "Insurer") evidencing the insurance guaranteeing the timely payment of
principal and interest of some of the obligations comprising the corpus of the
Fund, as more fully set forth in the Preliminary Prospectus.  All other
obligations included in the deposit described above will be covered by
insurance obtained by the issuer of such obligations from the Insurer
guaranteeing timely payment of principal and interest.  Such insurance will
provide that the amount paid by the Insurer in respect of any Bond may
not exceed the amount of principal and interest due on the Bond and such
payment will in no event relieve the issuer from its continuing obligation
to pay such defaulted principal and interest in accordance with the terms of
the obligation.

    Section 2.04 of the Indenture provides that each State Trust is a separate
and distinct trust for all purposes, the assets of one State Trust may not be
commingled with the assets of any other State Trust, and that the expenses of
one State Trust shall not be charged against any other State Trust.  Section
2.04 further provides that the certificates representing the ownership of an
undivided fractional interest in one State Trust shall not be exchangeable for
certificates representing the ownership of an undivided fractional interest in
any other State Trust.

<PAGE>

     The Indenture provides further, among other things, that the Trustee
shall:

    A.  Collect all interest and monies payable to the New Jersey Trust, and
hold the funds collected in trust on behalf of the Unitholders of the
New Jersey Trust;

    B.  Set aside from such funds any amounts necessary for the reimbursement
of advances and for the payment of expenses, taxes and governmental charges in
respect of the New Jersey Trust;

    C.  Distribute all remaining amounts semi-annually, or monthly or
quarterly if so elected by a Unitholder, to the Unitholders in proportion
to their interest in the New Jersey Trust;

    D.  Redeem any certificates tendered for redemption by a Unitholder
provided that the Trustee has notified the Depositor of the tender and the
Depositor has failed to indicate within a time specified in the Indenture that
it will purchase the tendered certificates from the tendering Unitholder;

    E.  Sell or liquidate any or all Bonds at the sole direction of the
Depositor and at such price and time and in such manner as shall be determined
by the Depositor, provided that the Depositor has determined that any one or
more of certain conditions specified in the Indenture exists;

    F.  In connection with an offer made by an obligor of any of the Bonds to
issue new obligations, in exchange and substitution for any issue of Bonds
pursuant to a plan for the refunding or refinancing of such Bonds, pursuant to
the sole instruction of the Depositor in writing, reject such offer and either
hold or sell such Bonds, or accept or reject such offer or to take any other
action with respect thereto as the Depositor may deem proper; and

    G.  At the direction of the Depositor, acquire Replacement Bonds, as
defined in the Prospectus, to make up the original corpus of the New Jersey
Trust in the event of a failure to deliver any Bond that has been purchased
for the New Jersey Trust under a contract, including those Bonds purchased on
a "when, as and if issued" basis.

    The Trustee has no power of sale except (a) on order of the Depositor as
stated herein, (b) to provide funds, not otherwise available, to pay taxes,
charges, expenses, fees or indemnities, (c) in case of default on any of the
Bonds, but only after notification of the Depositor, and provided that the
Depositor has not, within 30 days of such notification, given any instructions
to sell or to hold, or has not taken any other action in connection with, such
Bonds, or (d) for the purpose of redeeming certificates tendered by any
Unitholder.  The Trustee has no  power to reinvest, except as stated in
Section 3.08 of the Indenture.  Such limited power of reinvestment is in
furtherance of the Trustee's obligation to protect the trust assets, and does
not constitute power to vary investments.

    The Indenture provides further, among other things, that the Unitholders:

    A.  May tender their certificate or certificates to the Trustee for
redemption except in limited circumstances;

    B.  Will not have any right to vote or in any manner otherwise control the
operation and management of the Fund, the New Jersey Trust, or the obligations
of the Depositor or Trustee;

    C.  May elect to receive distributions from the New Jersey Trust on a
monthly or quarterly basis;

    D.  May terminate the New Jersey Trust at any time by written consent of
100% of the Unitholders of the New Jersey Trust; and

    E.  Shall be under no liability to any third persons by reason of any
action taken by the Depositor or Trustee or any other Unitholder, or any
other cause whatsoever.

<PAGE>

    You have advised that, in the opinion of Messrs. Chapman and Cutler, for
Federal income tax purposes the Fund and New Jersey Trust will not be taxable
as a corporation or association but will be governed by the provisions of
Subchapter J (relating to trusts) of Chapter 1 of the Internal Revenue Code of
1986, as amended.  Each Unitholder will be considered the owner of a
pro rata portion of the New Jersey Trust and will be subject to tax on the
income therefrom under the provisions of Subpart E of Subchapter J of
Chapter 1 of the Internal Revenue Code of 1986, as amended.  The New Jersey
Trust itself will not be subject to Federal income taxes.  For Federal income
tax purposes, each item of trust income will have the same character in the
hands of the Unitholder as it would have in the hands of the Trustee.
Accordingly, to the extent that the income of the New Jersey Trust consists
of interest excludable from gross income under Section 103 of the Internal
Revenue Code of 1986, as amended, such income will be excludable from Federal
gross income of the Unitholder.  Furthermore, any proceeds paid under
the insurance policy or policies issued to the Trustee of the Fund with re-
spect to each Bond which represent maturing interest on defaulted obligations
held by the Trustee will be excludable from Federal gross income if, and to
the same extent as, such interest would have been so excludable if paid by the
issuer of the defaulted obligations and the excludability from Federal
gross income of interest on Bonds which may be insured by  policies issued
directly to the respective Bond issuers will not be affected if the source
of any interest payment is from policy proceeds.

    Based on our examination of the Prior Series Indenture, your advice that
the  Indenture is identical in all material respects to the Prior Series
Indenture, your advice that the opinion of Messrs. Chapman and Cutler with
respect to the Federal income tax status of the Fund, its constituent State
Trusts and its Unitholders dated as of the date hereof is identical in all
material respects to its counterpart in the Prior Series, and, with respect
to Federal income tax matters, with your approval, relying solely upon the
opinion of Messrs. Chapman and Cutler, and our examination of such other
documents, records and matters of law as we deem necessary, we are of the
opinion that for New Jersey state and local tax purposes:

    1.  The New Jersey Trust will be recognized as a trust and not an
association taxable as a corporation.  The New Jersey Trust will not be
subject to the New Jersey Corporation Business Tax or the New Jersey
Corporation Income Tax.

    2.  With respect to the non-corporate Unitholders who are residents
of New Jersey, the income of the New Jersey Trust which is allocable to each
such Unitholder will be treated as the income of such Unitholder
under the New Jersey Gross Income Tax.  Interest on the underlying Bonds which
would be exempt from New Jersey Gross Income Tax if directly received by such
Unitholder will retain its status as tax-exempt interest when received
by the New Jersey Trust and distributed to such Unitholder.  Any
proceeds paid under the insurance policy or policies issued to the Trustee of
the Fund with respect to each Bond or under individual policies obtained by
issuers of Bonds which represent maturing interest on defaulted obligations
held by the Trustee will be exempt from New Jersey Gross Income Tax if, and to
the same extent as, such interest would have been so exempt if paid by the
issuer of the defaulted obligations.

    3.  A non-corporate Unitholder will not be subject to the New
Jersey Gross Income Tax on any gain realized either when the New Jersey Trust
disposes of a Bond (whether by sale, exchange, redemption, or payment at
maturity), when the Unitholder redeems or sells his Units, or upon
payment of any proceeds under the insurance policy or policies issued to
the Trustee of the Fund with respect to each Bond or under individual policies
obtained by issuers of Bonds which represent maturing principal on defaulted
obligations held by the Trustee.  Any loss realized on such disposition may
not be utilized to offset gains realized by such Unitholder on the
disposition of assets the gain on which is subject to the New Jersey Gross
Income Tax.

    4.  Units of the New Jersey Trust may be taxable on the death of a
Unitholder under the New Jersey Transfer Inheritance Tax Law or the New
Jersey Estate Tax Law.

    5.  If a Unitholder is a corporation subject to the New Jersey
Corporation Business Tax or New Jersey Corporation Income Tax, interest from
the Bonds in the New Jersey Trust which is allocable to such corporation will
be includable in its entire net income for purposes of the New Jersey
Corporation Business Tax or New Jersey Corporation Income Tax, less any
interest expense incurred to carry such investment to the extent such interest
expense has not been deducted in computing Federal taxable income.  Net gains
derived by such corporation on the disposition of the Bonds by the New Jersey
Trust or on the disposition of its Units will be included in its entire net
income for purposes of the New Jersey Corporation Business Tax or New Jersey
Corporation Income Tax.  Any proceeds paid under the insurance policy or
policies issued to the Trustee of the Fund with respect to each Bond or
under individual policies obtained by issuers of Bonds which represent
maturing interest or maturing principal on defaulted obligations held by the
Trustee will be included in its entire net income for purposes of the New
Jersey Corporation Business Tax or New Jersey Corporation Income Tax if, and
to the same extent as, such interest or proceeds would have been so included
if paid by the issuer of the defaulted obligations.

<PAGE>

    We have not examined any of the obligations to be deposited in the Fund,
and express no opinion as to whether the interest on any such obligations
would in fact be tax-exempt if directly received by a Unitholder; nor
have we made any review of the proceedings relating to the issuance of Bonds
or the basis for bond counsel opinions.

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm and a summary of
this opinion included in such Registration Statement and the Prospectus
included therein.  In giving such consent we do not thereby admit that we
are in the category of persons whose consent is required by Section 7 of
the Securities Act of 1933, as amended, and the rules and regulations
thereunder.

     Except as indicated in the immediately preceding paragraph hereof and
except with our prior written consent, this opinion may not be quoted in
whole or in part or otherwise referred to in any document or instrument
or be furnished to or relied upon by any person other than the addressee
and United States Trust Company of New York, as Trustee (including any
successor trustee).

Very truly yours,

John Nuveen & Co. Incorporated

Chicago, Illinois  60606

RE:  Nuveen Tax-Exempt Unit Trust, Series 711
      
     Pennsylvania Insured Trust 175

Gentlemen:

    You have requested our opinion as to the Pennsylvania tax aspects of the
above-captioned Trust(s) (the "Pennsylvania Trust(s)") which is (are) a part
of the Nuveen Tax-Exempt Unit Trust Series 711 ("Fund").  The Fund is
organized under the Trust Indenture and Agreement, of even date, between John
Nuveen & Co. Incorporated, as Depositor, and United States Trust Company of
New York, as Trustee.  The Fund will contain several trusts, including the
Pennsylvania Trust(s), which will issue Units of fractional undivided
interests.  The Units will be purchased by various investors ("Unit Holder").
Each Unit of the Pennsylvania Trust(s) represents a fractional undivided
interest in the principal and net income of such Trust(s) in the ratio of ten
Units for each $1,000 of value of the obligations initially acquired by such
Trust(s).  Each Pennsylvania Trust will be administered as a distinct entity
with separate certificates, investments, expenses, books and records.
 
    The proceeds of the sale of the Units will be invested primarily in
interest-bearing obligations issued by or on behalf of the Commonwealth of
Pennsylvania, its agencies and instrumentalities, or political subdivisions
thereof, including any county, city, borough, town, township, school disrict,
municipality, and local housing or parking authority in the Commonwealth of
Pennsylvania or issued by Puerto Rico, the Virgin Islands, Guam or the
Northern Mariana Islands ("Bonds").  Distributions of the interest received by
the Trust will be made semi-annually unless the Unit Holder elects otherwise.
In the opinion of bond counsel to each issuer, the interest on all bonds in
the Trust is exempt fromn federal income tax under existing law.

    You have advised us that for federal income tax purposes each Pennsylvania
Trust will not be taxable as an association but will be governed by the
provisions of Subchapter J (relating to Trusts) of Chapter 1 of the Internal
Revenue Code of 1986.  Each Unit Holder will be considered the owner of a pro
rata portion of the Unit Holder's respective Pennsylvania Trust and will be
subject to tax on the income therefrom under the provisions of Subpart E of
Subchapter J of Chapter 1 of the Internal Revenue Code of 1986. A Pennsylvania
Trust itself will not be subject to federal income taxes. For federal income
tax purposes, each item of trust income will have the same character in the
hands of a Unit Holder as it would have in the hands of the Trustee.
Accordingly, to the extent that the income of a Pennsylvania Trust consists of
interest excludable from gross income under Section 103 of the Internal
Revenue Code of 1986, such income will be excludable from federal gross income
of the Unit Holder.

    Based upon the above facts, it is our opinion that for Pennsylvania state
and local tax purposes, a Pennsylvania Trust will be recognized as a trust not
taxable as a corporation.

    Various personal property taxes are in effect in Pennsylvania, however, 
each of them exempts, inter alia, Bonds, cash, checking and savings accounts 
in and certificates of deposit issued by commercial banks, savings 
institutions or trust companies and United States Treasury obligations.  In
general, these taxes apply to a specified list of items of intangible 
personal property including, inter alia, mortgages and other evidences of
indebtedness and shares of stock issued by business corporations not doing
business in Pennsylvania.  The taxes referred to above include the County 
Personal Property Tax imposed on residents of Pennsylvania by the Act of
June 17, 1913, P.L. 507, as amended, the additional personal property taxes 
imposed on Pittsburgh residents by the School District of Pittsburgh under the 
Act of June 20, 1947, P.L. 733, as amended, and by the City of Pittsburgh by 
Ordinance No. 599 of December 28, 1967, under the Act of December 31, 1965, 
P.L. 1257, and any additional personal property taxes that the School District 
of Philadelphia may reimpose on Philadelphia residents under the authority 
contained in the Act of May 23, 1949, P.L. 1676, as amended.  Units evidencing 
fractional undivided interests in a Pennsylvania Trust will not be subject to 
any of these personal property taxes to the extent of that proportion of a 
Pennsylvania Trust represented by Bonds and other exempt assets. Only that 
proportion of the Units represented by taxable assets will be subject to the 
personal property taxes.  Pennsylvania Trust Units may be taxable under the 
Pennsylvania inheritance and estate taxes.
 
    The interest and gain from obligations issued by the Commonwealth of        
Pennsylvania or by its political subdivisions or by any public authority of 
either are exempt from tax under the Act of August 31, 1971, P.L. 395, 
Act No. 94. However, that Act was repealed by the Act of December 3, 1993, 
P.L. 473, Act No. 68 ("Act 68 of 1993") with respect to obligations issued on 
or after February 1, 1994.  Pursuant to Act 68 of 1993, profits, gains or 
income derived from the sale, exchange or other disposition of exempt 
government obligations issued after February 1, 1994 will be subject to state 
or local taxation although interest and "income" derived from the exempt 
obligations will continue to be exempt from all state and local taxation.  
Therefore, the proportion of income representing interest from Bonds 
distributable to Unit Holders is not taxable under the Pennsylvania
Personal Income Tax imposed by Article III of the Pennsylvania "Tax Reform
Code of 1971", as amended by the Act of August 31, 1971, P.L. 362, Act No. 93,
or under the Corporate Net Income Tax imposed on corporations by Article IV of
the Tax Reform Code.  Similarly, such interest will not be taxable under the 
Philadelphia School District Investment Income Tax imposed on 
<PAGE>

Philadelphia resident individuals under the authority of the Act of August 9,
1963, P.L. 640, as implemented by Section 19-1804 of the Philadelphia Code,
as amended, and resolutions of the Board of Education of the School District
of Philadelphia made pursuant to the ordinances, and such interest will not be 
subject to any of the taxes on net income from business activities
in Philadelphia under Philadelphia Code Sections 19-1500 and 19-2600, imposing
a Net Profits Tax and a Business Privilege Tax respectively.  The City and
School District of Pittsburgh do not impose any taxes on unearned income.
 
    Under the Pennsylvania Personal Income Tax Law, personal income tax is
imposed upon the following specified classes of income:  (1) compensation for
services, (2) net profits from the operation of a business, profession, or 
other activity, (3) net gains or income from the disposition of property, (4) 
net gains or income in the form of rents and royalties, (5) dividends, (6) 
interest from obligations not otherwise exempt, (7) gambling and lottery
winnings, (8) net gains or income from estates or trusts which fall under any 
of the preceding classifications.  Although there is no published authority
on the question, it is our opinion that any insurance proceeds paid in lieu of
interest on defaulted tax-exempt obligations will be exempt from Pennsylvania 
Personal Income Tax either as payment in lieu of tax-exempt interest or as 
payments of insurance proceeds which are not included in any of the classes 
of income specified as taxable under the Pennsylvania Personal Income Tax 
Law.  Since Pennsylvania Corporate Net Income Tax is imposed upon the 
corporation's net income for federal income tax purposes, because such
insurance proceeds will be excluded from the federal income tax base, such
proceeds will not be subject to the Pennsylvania Corporate Net Income Tax.
Finally, since proceeds from insurance policies are expressly excluded from
the Philadelphia School District Investment Income Tax, insurance proceeds
paid to replace defaulted payments under any Bonds held by the Pennsylvania
Trust(s) will not be subject to this tax.

    Under Act 68 of 1993, a Unit Holder's share of gain upon disposition of a 
Bond issued on or after February 1, 1994 by the Pennsylvania Trust, whether by 
sale, exchange, redemption or payment at maturity, will be taxable under the 
Pennsylvania Personal Income Tax.  Gains on the disposition of Bonds issued 
before February 1, 1994 will continue to be exempt.  See 72 P.S. Section 
7303 (a) (3) and 61 Pa. Code Section 121.9 (b) (3).  While there is no
published authority with respect to the treatment of such gains for purposes of
the Philadelphia School District Investment Income Tax, it is our opinion that
gains upon dispositions of Bonds issued before February 1, 1994 are exempt 
from this tax under Act of August 31, 1971, P.L. 395, Act No. 94, and, if the 
question were litigated, the Pennsylvania courts should so hold.  Gains on the
disposition of Bonds issued on or after February 1, 1994 will be taxable.
In any event, the Philadelphia School District Investment Income Tax has no 
application to any gain on the disposition of property held for more than six 
months.

    In C.C. Collings & Co., Inc. vs. Commw. of Pennsylvania, 514 A.2d 1373
(1986),  and two related cases, the Supreme Court of Pennsylvania held that 
gains or losses from the sale of obligations of the Commonwealth of 
Pennsylvania, its political subdivisions, instrumentalities and agencies 
are not subject to the Corporate Net Income Tax.  Profits, gains or income 
derived from the sale, exchange or other disposition of those exempt 
obligations issued on or after February 1, 1994, however, will be subject 
to tax pursuant to Act 68 of 1993.

    There is no published authority under any of the Pennsylvania state and
local income taxes described above with respect to gain from the redemption
or sale of a Unit.  To the extent that such gain represents the
Unit Holder's share of any unrealized gain on the Bonds issued before 
February 1, 1994 and held by the Trust, it is our opinion that such gain is 
exempt from the above-described Pennsylvania state and local income taxes and, 
if the question were litigated, the Pennsylvania courts should so hold.  To the
extent that such gain is attributable to unrealized gain on bonds issued on or 
after February 1, 1994, such gain will be taxable under such taxes. In any 
event, the Philadelphia School District Investment Income Tax has no 
application to any gain on the disposition of property held for more than 
six months.
 
    Interest on obligations of Puerto Rico, the Virgin Islands, Guam, or the
Northern Mariana Islands is, under federal law, exempt from taxation by states
and municipalities.  Federal law does not expressly exclude from taxation gain
realized upon the disposition of such obligations.  Therefore, a disposition
of such obligations by a Pennsylvania Trust could be a taxable event to a
Holder under each of the Pennsylvania state and local income taxes discussed
in the preceding paragraphs.  See Willcuts v. Bunn, 282 U.S. 216 (1931); U.S.
v. Stewart, 311 U.S. 60 (1940).  Similarly, to the extent that gain on the
redemption or sale of a Unit represents unrealized gain on such obligations
held by a Pennsylvania Trust, such gain could be taxable.  

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (No. 33-51205) relating to the Units referred to
above, and to the reference to our firm as special Pennsylvania tax counsel in
said Registration Statement and in the related Prospectus.

Very truly yours,

RE: Nuveen Tax-Exempt Unit Trust, Series 711

Gentlemen:

    This is in response to your requests regarding the above-
captioned fund which consists of separate underlying unit investment trusts
(the "trusts"), SEC file # 33-51205.

    We have reviewed the information presented to us and have assigned a 'AAA'
rating to the units of each insured trust and a 'AAA' rating to the securities
contained in each insured trust.  The ratings are direct reflections of the
portfolio of each insured trust, which will be composed solely of securities
covered by bond insurance policies that insure against default in the payment
of principal and interest on the securities contained in each insured trust
for as long as they remain outstanding.  We understand that the bonds
described in the prospectus are the same as those in the attached list.
Since such policies have been issued by MBIA which has been assigned a 'AAA'
claims paying ability rating by S&P, S&P has assigned a 'AAA' rating to
the units of each insured trust and a 'AAA' rating to the securities contained
in each insured trust.

    You have permission to use the name of Standard & Poor's Corporation and
the above-assigned rating in connection with your dissemination of
information relating to the insured trusts provided that it is understood that
the ratings are not "market" ratings nor recommendations to buy, hold or sell
the units of the insured trusts or the securities contained in the insured
trusts.  Further, it should be understood the rating on the units of each
insured trust does not take into account the extent to which the trust's
expenses or portfolio asset sales for less than the trust's purchase price
will reduce payment to the unit holders of the interest and principal
required to be paid on the portfolio assets.  S&P reserves the right to
advise its own clients, subscribers, and the public of the ratings.  S&P
relies on the sponsor and its counsel, accountants, and other experts for the
accuracy and completeness of the information submitted in connection with the
ratings.  S&P does not independently verify the truth or accuracy of any such
information.

    This letter evidences our consent to the use of the name of Standard &
Poor's Corporation in connection with the rating assigned to the units of
each insured trust in the registration statement or prospectus relating to the
units and the trusts.  However, this letter should not be construed as a
consent by us, within the meaning of Section 7 of the Securities Act of 1933,
to the use of the name of Standard & Poor's Corporation in connection with the
ratings assigned to the securities contained in the insured trusts.  You are
hereby authorized to file a copy of this letter with the Securities and
Exchange Commission.

    Please be certain to send us three copies of your final prospectus as
soon as it becomes available.  Should we not receive them within a reasonable
amount of time after the closing or should they not conform to the
certification received by us, we reserve the right to nullify the ratings.

                                   MEMORANDUM

                 Nuveen Tax-Exempt Unit Trust, Series 711
                               File No. 33-51205


    The Prospectus and the Indenture filed with Amendment No. 1 of the
Registration Statement on Form S-6 have been revised to reflect information
regarding the execution of the Indenture and the deposit of bonds on 01/06/94,
and to set forth certain statistical data based thereon.  In addition, there 
are a number of other changes from the Prospectus as originally filed to which
reference is made, including the increase in the size of the Fund, a
corresponding increase in the number of Units and a change in the individual
trusts constituting the Fund.  All references to the Units, prices and related
statistical data will apply to each trust of the Fund and the Units thereof
individually.

    Except for such updating, an effort has been made to set forth below each 
of the changes and also to reflect the same by marking the Prospectus 
transmitted with the Amendment.  Also, differences between the Final 
Prospectus relating to the previous series of the Nuveen Tax-Exempt Unit 
Trust and the subject Prospectus have been indicated.
