NUVEEN  Tax-Exempt Unit Trusts
             PROSPECTUS
            Series 734
             June 14, 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 734  consists  of  five  underlying
separate unit investment trusts designated as Connecticut Traditional Trust 265,
Virginia  Traditional Trust 288, Arizona Insured Trust 33, Florida Insured Trust
192 and New York  Insured Trust 218. 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 (normally  five business days after purchase)  is
added  to the Public Offering Price. The  sales charge is reduced on a graduated
scale for sales involving at least $50,000  or 500 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.
 
UNITS OF THE TRUST ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR ENDORSED
BY, ANY BANK AND ARE NOT FEDERALLY INSURED OR OTHERWISE PROTECTED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER AGENCY AND
INVOLVE INVESTMENT RISK, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL.
 
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 effect of a
first distribution which may be less than a regular distribution or may be  paid
at  some point after 30 days (or a  second distribution which may be less than a
normal distribution for Unitholders who choose quarterly or semi-annual plans of
distribution), and it also does not  take into account the difference in  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 734
    
 
   
1.  WHAT IS THE NUVEEN TAX-EXEMPT UNIT TRUST, SERIES 734?
    
 
   
Series  734 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 Connecticut  Traditional Trust  265, Virginia  Traditional
Trust  288, Arizona  Insured Trust  33, Florida Insured  Trust 192  and New York
Insured Trust 218. 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." This Series was created under the laws of the
State  of New York  pursuant to a  Trust Indenture and  Agreement dated June 14,
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
    
 
                                       6
<PAGE>
   
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  Connecticut  Traditional Trust,
$3,500,000 in the Virginia Traditional Trust, $3,500,000 in the Arizona  Insured
Trust,  $3,500,000 in the Florida  Insured Trust and $3,500,000  in the New York
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 Connecticut Traditional Trust,  35,000 Units of the Virginia  Traditional
Trust,  35,000 Units of the  Arizona Insured Trust, 35,000  Units of the Florida
Insured Trust and  35,000 Units of  the New York  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. Only Units of
the  Virginia Traditional  Trust are offered  for sale to  Virginia residents by
this Prospectus.
    
 
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.
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.

CONNECTICUT TRADITIONAL TRUST 265
    
   
    The Portfolio of Connecticut Traditional Trust 265 consists of 7 obligations
issued by entities located in Connecticut and one obligation issued by an entity
located  in the  Territory of Puerto  Rico. One Bond  in the Trust  is a general
obligation of the  governmental entity issuing  it and is  backed by the  taxing
power 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: Dedicated-Tax Supported Revenue, 1; College and University  Revenue,
1;  Health Care Facility  Revenue, 3; Industrial Revenue,  1; Water and/or Sewer
Revenue, 1.  Eight  issues  in  the  Trust  were  rated  by  Standard  &  Poor's
Corporation  as  follows: 7--AAA,  1--AA+. Eight  issues  were rated  by Moody's
Investors Service, Inc. as follows: 7--Aaa, 1--Aa.
    
   
    At the Date of Deposit, the average maturity of the Bonds in the Connecticut
Traditional Trust is 26.3 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 28.6% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 26.7% 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 35% of  the aggregate  principal amount  of the  Bonds in  the
Trust  are  obligations of  issuers whose  revenues  are primarily  derived from
hospitals or other health care services,  all of which is covered by  insurance.
The  source  of payment  for these  Bonds  is insured  by a  commercial insurer.
Consequently, the credit ratings of such Bonds essentially reflect the  strength
of  the insurance or guarantee  and, depending upon the  actual structure of the
bond issue, are typically  rated "Aaa" or  "Aa" by Moody's or  "AAA" or "AA"  by
Standard & Poor's.
 
    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 June 6, 1994
and June 13, 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  Connecticut  Traditional Trust,  less estimated  expenses, is  estimated to
accrue at the rate of $.01504 per Unit
    
 
                                       9

per day under  the semi-annual plan  of distribution, $.01498  per Unit per  day
under  the quarterly plan of distribution and $.01490 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 Connecticut  Traditional
Trust under the various plans appear in the following table based upon estimated
Net Annual Interest Income at the Date of Deposit:

TAX STATUS--CONNECTICUT TRADITIONAL TRUST
 
    For  a discussion of the Federal tax  status of income earned on Connecticut
Traditional Trust Units, see Section 11.
 
    The assets of the Connecticut Traditional Trust will consist of  obligations
issued by or on behalf of the State of Connecticut or its political subdivisions
or  public instrumentalities, state or  local authorities, districts, or similar
public entities created under the laws of  the State of Connecticut or by or  on
behalf  of  a  United  States  territory  or  possession  the  interest  on  the
obligations of  which Federal  law  would prohibit  Connecticut from  taxing  if
received   directly  by  a  Unitholder  (the  "Bonds").  Certain  Bonds  in  the
Connecticut Traditional Trust that  were issued by the  State of Connecticut  or
governmental  authorities  located  in  Connecticut  were  issued  prior  to the
enactment of a Connecticut tax on the interest income of individuals; therefore,
bond counsel to the issuers  of such Connecticut Bonds did  not opine as to  the
exemption  of the interest on such Connecticut Bonds from such tax. However, the
Sponsor and special counsel  to the Trusts for  Connecticut tax matters  believe
that  such interest  will be  so exempt.  Interest on  Connecticut Bonds  in the
Connecticut Traditional  Trust issued  by  other issuers,  if  any, is,  in  the
opinion of bond counsel to such issuers, exempt from state taxation.

<PAGE>
    In  the opinion of  Day, Berry &  Howard, special counsel  to the Series for
Connecticut tax matters, which relies explicitly  on the opinion of Chapman  and
Cutler regarding Federal income tax matters, under existing Connecticut law:
 
        The  Connecticut  Traditional Trust  is  not liable  for  any tax  on or
    measured by net income imposed by the State of Connecticut.
 
   
        Interest income from a Bond held by the Connecticut Traditional Trust is
    not taxable under the Connecticut tax  on the Connecticut taxable income  of
    individuals,  trusts, and estates (the  "Connecticut Income Tax"), when such
    interest is received by the Connecticut Traditional Trust or distributed  by
    it to a Unitholder.
    
 
        Gains  and  losses recognized  by a  Unitholder  for Federal  income tax
    purposes upon the maturity,  redemption, sale, or  other disposition by  the
    Connecticut  Traditional Trust of a Bond held by the Connecticut Traditional
    Trust or upon the redemption,  sale, or other disposition  of a Unit of  the
    Connecticut Traditional Trust held by a Unitholder are taken into account as
    gains  or losses, respectively, for purposes  of the Connecticut Income Tax,
    except that, in the case of a  Unitholder holding a Unit of the  Connecticut
    Traditional  Trust as a capital asset, such gains and losses recognized upon
    the sale or  exchange of  a Bond  issued by  or on  behalf of  the State  of
    Connecticut,  any political subdivision  thereof, or public instrumentality,
    state or local authority, district,  or similar public entity created  under
    the  laws of  the State  of Connecticut (a  "Connecticut Bond")  held by the
    Connecticut Traditional Trust are excluded from gains and losses taken  into
    account  for purposes  of such  tax and  no opinion  is expressed  as to the
    treatment for purposes of such tax  of gains and losses recognized upon  the
    maturity  or  redemption  of  a Connecticut  Bond  held  by  the Connecticut
    Traditional Trust or, to  the extent attributable  to Connecticut Bonds,  of
    gains  and losses recognized upon the redemption, sale, or other disposition
    by a Unitholder of a Unit of the Connecticut Traditional Trust held by him.
 
        The portion of any  interest income or capital  gain of the  Connecticut
    Traditional  Trust that is allocable to a  Unitholder that is subject to the
    Connecticut corporation business tax  is includable in  the gross income  of
    such Unitholder for purposes of such tax.
 
        An interest in a Unit of the Connecticut Traditional Trust that is owned
    by  or attributable to  a Connecticut resident  at the time  of his death is
    includable in his gross  estate for purposes  of the Connecticut  succession
    tax and the Connecticut estate tax.
 
TAX DISCLOSURE--CONNECTICUT
 
    The  Connecticut  Income  Tax  was enacted  in  August,  1991.  Generally, a
Unitholder recognizes gain or loss for purposes  of this tax to the same  extent
he  recognizes gain  or loss  for Federal  income tax  purposes. Ordinarily this
would mean  that gain  or loss  would be  recognized by  a Unitholder  upon  the
maturity,  redemption, sale, or other disposition by the Connecticut Traditional
Trust of a Bond held by it,  or upon the redemption, sale, or other  disposition
of a Unit of the Connecticut Traditional Trust held by the Unitholder.
 
    However, on June 19, 1992, Connecticut legislation was adopted that provides
that  gains and losses  from the sale  or exchange of  Connecticut Bonds held as
capital assets will not  be taken into account  for purposes of the  Connecticut
Income  Tax for taxable  years starting on or  after January 1,  1992. It is not
clear whether  this  provision would  apply  to gain  or  loss recognized  by  a
Unitholder  upon  the  maturity or  redemption  of  a Connecticut  Bond  held by
 
                                       11
<PAGE>
the Connecticut Traditional Trust or, to the extent attributable to  Connecticut
Bonds held by the Connecticut Traditional Trust, to gain or loss recognized by a
Unitholder  upon the  redemption, sale,  or other disposition  of a  Unit of the
Connecticut Traditional Trust held by  the Unitholder. Unitholders are urged  to
consult their own tax advisors concerning these matters.
 
ECONOMIC FACTORS--CONNECTICUT
 
    Investors  should  be aware  that  manufacturing was  historically  the most
important economic activity  within the State  of Connecticut but,  in terms  of
number  of persons  employed, manufacturing has  declined in the  last ten years
while both trade and service-related industries have become more important,  and
in  1992  manufacturing  accounted  for  only  20.1%  of  total non-agricultural
employment in Connecticut. Defense-related business represents a relatively high
proportion of  the manufacturing  sector; reductions  in defense  spending  have
already  had  a substantial  adverse effect  on  Connecticut's economy,  and the
State's largest  defense contractors  have announced  substantial planned  labor
force reductions scheduled to occur over the next four years. Connecticut is now
in  a recession, the depth and duration  of which are uncertain. Moreover, while
unemployment in the State as a  whole had generally remained below the  national
level,  as of May 1993,  the estimated rate of  unemployment in Connecticut on a
seasonally adjusted basis was 7.4%, compared to 6.9% for the United States as  a
whole,  and certain  geographic areas  in the State  have been  affected by high
unemployment and poverty. The State derives over 70% of its revenues from  taxes
imposed by it, the most important of which have been the sales and use taxes and
the corporation business tax, each of which is sensitive to changes in the level
of  economic activity in the  State, but the Connecticut  Income Tax, enacted in
1991, is expected  to supersede  each of  them in  importance. There  can be  no
assurance  that general economic difficulties  or the financial circumstances of
the State or its towns and cities will not adversely affect the market value  of
the Connecticut Bonds in the Connecticut Traditional Trust or the ability of the
obligors to pay debt service on such Connecticut Bonds.
 
    The  General Fund budget adopted by  Connecticut for the 1986-87 fiscal year
contemplated both revenues and expenditures of $4,300,000,000. The General  Fund
ended  the 1986-87 fiscal year with a  surplus of $365,200,000. The General Fund
budget for  the  1987-88 fiscal  year  contemplated General  Fund  revenues  and
expenditures  of  $4,915,800,000. However,  the General  Fund ended  the 1987-88
fiscal year with a deficit of $115,600,000. The General Fund budget adopted  for
the   1988-89  fiscal  year  anticipated   that  General  Fund  expenditures  of
$5,551,000,000 and certain educational  expenses of $206,700,000 not  previously
paid  through the General Fund  would be funded in  part from surpluses of prior
years and in part from higher tax revenues projected to result from tax laws  in
effect  for  the  1987-88  fiscal  year  and  stricter  enforcement  thereof;  a
substantial deficit was projected during the third quarter of the 1988-89 fiscal
year, but largely because of tax law changes that took effect before the end  of
the  fiscal year, the deficit  was kept to $28,000,000.  The General Fund budget
adopted for the  1989-90 fiscal year  anticipated expenditures of  approximately
$6,224,500,000 and, by virtue of tax increase legislation enacted to take effect
generally  at the beginning of the fiscal year, revenues slightly exceeding such
amount. However, largely  because of  tax revenue shortfalls,  the General  Fund
ended  the 1989-90  fiscal year  with a  deficit for  the year  of $259,500,000,
wiping out reserves for such events
 
                                       12
<PAGE>
built up in prior years. The General Fund budget adopted for the 1990-91  fiscal
year  anticipated  expenditures of  $6,433,000,000,  but no  significant  new or
increased taxes were enacted. Primarily  because of significant declines in  tax
revenues  and unanticipated  expenditures reflective of  economic adversity, the
General Fund  ended the  1990-91 fiscal  year alone  with a  further deficit  of
$809,000,000.
 
    A  General Fund  budget for  the 1991-92 fiscal  year was  not enacted until
August  22,  1991.  This  budget   anticipated  General  Fund  expenditures   of
$7,007,861,328  and revenues of $7,426,390,000.  Projected decreases in revenues
resulting from a 25% reduction in the sales tax rate effective October 1,  1991,
the repeal of the taxes on the capital gains and interest and dividend income of
resident  individuals for  years starting after  1991, and the  phase-out of the
corporation business tax surcharge over two years commencing with taxable  years
starting after 1991 were expected to be more than offset by a new general income
tax  imposed at effective  rates not to  exceed 4.5% on  the Connecticut taxable
income of  resident  and  non-resident individuals,  trusts,  and  estates.  The
General  Fund  ended  the  1991-92  fiscal year  with  an  operating  surplus of
$110,000,000. The General Fund  budget for the  1992-93 fiscal year  anticipated
General  Fund expenditures of $7,372,062,859 and revenues of $7,372,210,000, and
the General Fund  ended the  1992-93 fiscal year  with an  operating surplus  of
$113,500,000.  Balanced General  Fund budgets for  the biennium  ending June 30,
1995, have been  adopted appropriating  expenditures of  $7,828,900,000 for  the
1993-94 fiscal year and $8,266,000,000 for the 1994-95 fiscal year. In addition,
expenditures of federal, State, and local funds in the twelve years started July
1,  1984,  for  repair  of  the  State's  roads  and  bridges  now  projected at
$9,500,000,000 are anticipated, a portion of the State's $4,100,000,000 share of
which would be financed by bonds expected to total $3,700,000,000 and by  direct
payments,  both of  which would  be supported  by a  Special Transportation Fund
first created by the General Assembly for the 1984-85 fiscal year.
 
    To fund operating cash  requirements, prior to the  1991-92 fiscal year  the
State  borrowed up to $750,000,000 pursuant to authorization to issue commercial
paper and  on  July 29,  1991,  it  issued $200,000,000  of  General  Obligation
Temporary  Notes, none of which  temporary borrowings are currently outstanding.
To fund the cumulative General Fund  deficit for the 1989-90 and 1990-91  fiscal
years,  the legislation enacted August 22,  1991, authorized the State Treasurer
to issue Economic  Recovery Notes up  to the aggregate  amount of such  deficit,
which  must be payable no later than June 30, 1996; at least $50,000,000 of such
Economic Recovery Notes, but not more than  a cap amount, is to be retired  each
fiscal  year commencing  with the  1991-92 fiscal  year, and  any unappropriated
surplus up to $205,000,000 in the General Fund  at the end of each of the  three
fiscal  years commencing with the 1991-92 fiscal  year must be applied to retire
such Economic  Recovery Notes  as  may remain  outstanding  at those  times.  On
September  25, 1991,  and October  24, 1991,  the State  issued $640,710,000 and
$325,002,000,  respectively,  of   such  Economic  Recovery   Notes,  of   which
$630,610,000 was outstanding as of March 1, 1994.
 
    As  a result  of the  State's budget  problems, the  ratings of  its general
obligation bonds were reduced by Standard &  Poor's from AA+ to AA on March  29,
1990, and by Moody's from Aa1 to Aa on April 9, 1990. Moreover, because of these
problems,  on September 13,  1991, Standard &  Poor's reduced its  rating of the
State's general obligation bonds  and certain other  obligations that depend  in
part  on the  creditworthiness of the  State to  AA-. On March  7, 1991, Moody's
downgraded its  ratings  of the  revenue  bonds of  four  Connecticut  hospitals
because  of  the effects  of  the State's  restrictive  controlled reimbursement
environment under which they have been operating.

    General obligation bonds  issued by Connecticut  municipalities are  payable
primarily  only from  ad velorem  taxes on property  subject to  taxation by the
municipality. Certain Connecticut municipalities have experienced severe  fiscal
difficulties  and  have reported  operating and  accumulated deficits  in recent
years. The  most notable  of these  is the  City of  Bridgeport, which  filed  a
bankruptcy  petition on June 7, 1991. The State opposed the petition. The United
States Bankruptcy Court for the District of Connecticut has held that Bridgeport
has authority to file such a petition but that its petition should be  dismissed
on  the grounds that Bridgeport  was not insolvent when  the petition was filed.
Regional economic difficulties, reductions  in revenues, and increased  expenses
could  lead  to  further  fiscal  problems  for  the  State  and  its  political
subdivisions, authorities, and agencies. Difficulty  in payment of debt  service
on  borrowings could result in declines, possibly  severe, in the value of their
outstanding obligations and increases in their future borrowing costs.
 
CONNECTICUT 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 under the Connecticut Income Tax. 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.

</TABLE>
 
- ------------------
 
        1  The Connecticut  Income Tax is  based on  Connecticut taxable income,
which is not tied to Federal taxable income. Connecticut taxable income is equal
to Connecticut adjusted gross income  ("CAGI") (which is Federal adjusted  gross
income  with  certain  modifications)  minus  the  allowable  personal exemption
($12,000 in the case of single  individuals; $24,000 for married persons  filing
jointly).   The  Connecticut  Income  Tax  provides  for  a  personal  exemption
phase-out, which essentially doubles  the effective marginal Connecticut  Income
Tax rate for single taxpayers whose CAGI is between $24,000 and $35,001 at which
point  the personal  exemption is completely  phased out.  For married taxpayers
filing a joint  return, the effective  marginal Connecticut Income  Tax rate  is
doubled  where CAGI is between $48,000 and  $71,001, at which point the personal
exemption is completely phased out. It should be noted that for purposes of  the
personal  exemption  phase-out the  Tax  Act merely  references  "adjusted gross
income," which the tables assume is identical to CAGI. In addition, as reflected
in the rates shown,  the Connecticut Income  Tax provides for  a tax credit  (at
varying  percentages depending  on the taxpayer's  CAGI) against  the income tax
which is based on CAGI and, in effect, varies the income tax rate for taxpayers.
Investors should consult  their own  tax advisors  regarding the  effect of  the
credit on marginal tax rates at specific CAGI levels.
 
        2 It is assumed that CAGI is equal to Federal adjusted gross income. See
note  1 regarding  the impact  of CAGI on  the determination  of the Connecticut
Income Tax.
 
        3 The tables reflect  the effect of  limitations on itemized  deductions
and  the deduction for  personal exemptions. These  limitations were designed to
phase out certain benefits of such 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.
 
        4  Federal tax rate reverts to 36.0% after the 80% cap on the limitation
on itemized deductions has been met.
 
        5 Federal tax rate reverts to 39.6% after the 80% cap on the  limitation
on itemized deductions has been met.
 
        6 Includes taxpayers filing as surviving spouses.
 
        7  The Connecticut Income Tax has different marginal effective tax rates
that are  not  reflected  in  these  tables  for  persons  filing  as  heads  of
households.
 
    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  June 23,  1994. Contracts
  relating to  Bonds  with delivery  dates  after  the date  of  settlement  for
  purchase  made  on the  Date of  Deposit constitute  approximately 14%  of the
  aggregate principal amount of the Trust. (See Section 4.)

VIRGINIA TRADITIONAL TRUST 288
    
 
   
    The  Portfolio of Virginia  Traditional Trust 288  consists of 7 obligations
issued by  entities located  in Virginia.  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;  Health Care
Facility Revenue, 1; Water  and/or Sewer Revenue, 3.  Seven issues in the  Trust
were  rated by Standard & Poor's  Corporation as follows: 2--AAA, 1--AA, 1--AA-,
2--A+, 1-- A.  Seven issues  were rated by  Moody's Investors  Service, Inc.  as
follows: 2--Aaa, 2--Aa, 1--A1, 2--A.
    
 
   
    At  the Date of Deposit,  the average maturity of  the Bonds in the Virginia
Traditional 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 12.7% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 11.7% 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 42% of  the aggregate  principal amount  of the  Bonds in  the
Trust  are obligations of issuers whose revenues are primarily derived from sale
of water  and/or sewerage  services. Insurance  guaranteeing prompt  payment  of
interest and principal on certain of the Bonds in the Trust has been obtained by
the  issuer or underwriter of  such Bonds from a  commercial insurer. Such Bonds
are rated  "Aaa" or  "Aa" by  Moody's or  "AAA" or  "AA" by  Standard &  Poor's,
reflecting  those rating agencies' current assessment of the creditworthiness of
the insurer and its ability to pay claims on its policies of insurance. Thirteen
percent of the aggregate  principal amount of the  Bonds, included in the  above
amount,  are obligations  of issuers whose  revenues are  primarily derived from
sale of water and/or sewerage services, but which are covered by such insurance.
 
    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 June 10,
1994 and June 13, 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
 
                                       17
<PAGE>
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  Virginia Traditional Trust, less estimated expenses, is estimated to accrue
at the  rate  of  $.01574  per  Unit per  day  under  the  semi-annual  plan  of
distribution,  $.01569 per Unit per day under the quarterly plan of distribution
and $.01560 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 Virginia Traditional Trust
under  the various plans appear in the  following table based upon estimated Net
Annual Interest Income at the Date of Deposit:

TAX STATUS--VIRGINIA TRADITIONAL TRUST
 
    For a discussion  of the  Federal tax status  of income  earned on  Virginia
Traditional Trust Units, see Section 11.
 
    The   assets   of   the   Virginia  Traditional   Trust   will   consist  of
interest-bearing obligations  issued by  or  on behalf  of the  Commonwealth  of
Virginia,  its counties,  municipalities, authorities  or political subdivisions
and, provided the interest thereon is  exempt from Virginia income taxes by  the
laws  or treaties of  the United States, by  or on behalf  of the United States'
territories or possessions, including Puerto Rico, Guam, the Virgin Islands  and
the  Northern Mariana Islands, and  their political subdivisions and authorities
(the "Virginia Bonds").
 
                                       18
<PAGE>
    In the opinion of Christian, Barton, Epps, Brent & Chappell, special counsel
for the Series for Virginia tax matters, under existing law:
 
        The Virginia Traditional Trust will be  treated as a trust for  Virginia
    income tax purposes and not as an association taxable as a corporation. As a
    result,  income of  the Virginia  Traditional Trust  will be  treated as the
    income of the Unitholders.
 
        The calculation of Virginia taxable income begins with Federal  adjusted
    gross  income in the case of an  individual or Federal taxable income in the
    case of a corporation, estate or trust. Certain modifications are specified,
    but no such modification  requires the addition  of interest on  obligations
    such  as the Virginia Bonds in  the Virginia Traditional Trust. Accordingly,
    amounts representing  tax-exempt interest  for Federal  income tax  purposes
    received  or accrued by  the Virginia Traditional Trust  with respect to the
    Virginia Bonds, will not  be taxed to the  Virginia Traditional Trust or  to
    the Unitholders for Virginia income tax purposes.
 
        In  this  respect, to  the extent  that interest  on obligations  of the
    Commonwealth or  any political  subdivision  or instrumentality  thereof  is
    included  in federal adjusted  gross income, Virginia  law provides that the
    income shall  be  subtracted in  arriving  at Virginia  taxable  income.  In
    addition,  Virginia  income  tax  exemption  is  independently  provided for
    interest on  certain  obligations,  including  those  issued  by  industrial
    development   authorities  created  pursuant   to  the  Virginia  Industrial
    Development and  Revenue  Bond  Act, by  the  Virginia  Housing  Development
    Authority, by the Virginia Resources Authority and by the Virginia Education
    Loan Authority. Where such an independent exemption is provided, interest on
    such  obligations is exempt from Virginia  income taxation without regard to
    any exemption from  Federal income  taxes, including interest  which may  be
    subject  to Federal income tax in  the hands of a recipient  who is, or is a
    related person  to,  a substantial  user  of facilities  financed  with  the
    proceeds of obligations upon which such interest is paid.
 
        As  a general rule, to the extent that  gain (whether as a result of the
    sale of Virginia Bonds by the Virginia  Traditional Trust or as a result  of
    the sale of a Unit by the Unitholder) is subject to Federal income taxation,
    such  gain will  be included  in the  Unitholder's Virginia  taxable income.
    Under the language  of certain  enabling legislation, however,  such as  the
    Virginia Industrial Development and Revenue Bond Act, the Virginia Resources
    Authority  Act and  the Virginia  Housing Development  Authority Act, profit
    made on the sale of obligations issued by authorities created thereunder  is
    expressly  exempt from  Virginia income taxation.  Such enabling legislation
    does not appear  to require a  disallowance in the  calculation of  Virginia
    taxes  of any loss  that may be  deductible for Federal  income tax purposes
    with respect  to  such  obligations, although  the  Virginia  Department  of
    Taxation has taken a contrary view.
 
        No   income  tax  is  imposed  by   any  political  subdivision  of  the
    Commonwealth of Virginia.  The Commonwealth  of Virginia does  not impose  a
    gift  tax. The Virginia estate  tax is equal to  the maximum state death tax
    credit allowable against the Federal estate tax payable by the estate.
 
ECONOMIC FACTORS--VIRGINIA
 
    The Trust  is  susceptible  to political,  economic  or  regulatory  factors
affecting  issuers  of Virginia  Bonds. Without  intending  to be  complete, the
following briefly  summarizes some  of these  matters, as  well as  some of  the
complex factors affecting the financial situation in the
 
                                       19
<PAGE>
Commonwealth of Virginia (the "Commonwealth" or "Virginia"). This information is
derived  from sources that are generally available  to investors and is based in
part on information obtained from  various agencies in Virginia. No  independent
verification  has been  made of  the accuracy  or completeness  of the following
information.
 
    There can  be no  assurance that  current or  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 Virginia  Bonds
held in the portfolio of the Trust or the ability of particular obligors to make
timely payments of debt service on (or relating to) those obligations.
 
    The  Commonwealth's  financial  condition  is  supported  by  a  broad-based
economy,  including  manufacturing,  tourism,  agriculture,  ports,  mining  and
fisheries.  Manufacturing continues to be a  major source of employment, ranking
behind only services, wholesale and retail trade, and government (federal, state
and local). The federal government  is a major employer  in Virginia due to  the
heavy  concentration of federal employees  in the metropolitan Washington, D.C.,
segment of Northern Virginia  and the military employment  in the Hampton  Roads
area, which houses the nation's largest concentration of military installations.
However,  the expected retrenchment  of the military sector  as a consequence of
the end of the Cold War remains a cloud on the economic horizon and cutbacks can
be expected to occur.
 
    Although the Commonwealth enjoyed  an economic boom  in the mid-1980's,  the
Commonwealth's economy began to slow toward the end of the decade, and went into
a  recession with the rest of the nation  after July, 1990. Growth since the end
of the recession in March, 1991, has been weak.
 
    The impact  of  national trends  on  the  Commonwealth is  clearly  seen  in
personal   income  figures.   While  year-to-year  percentage   changes  in  the
Commonwealth  personal  income  parallel  those  at  the  national  level,   the
Commonwealth  figures  were higher  during  the first  half  of the  1980's. The
differential has  narrowed since  1988  and testifies  to  the lethargy  of  the
Commonwealth's  economy.  From a  peak  of 107  percent  of national  per capita
income, the Commonwealth has  experienced a relative decline  to 104 percent  in
1992.  Compared to the South Atlantic region, the Commonwealth's real per capita
income has declined slightly from a peak  of 109 percent in 1987 to 108  percent
in 1992.
 
    After  real  personal  income  in  the  Commonwealth  had  fallen  for seven
consecutive quarters ending with  the last quarter of  1991, it rose  throughout
1992.   Personal  income  declined  in  the  first  quarter  of  1993,  although
forthcoming data revisions are  likely to show  much milder decreases.  Overall,
the data suggest a fitful recovery continues.
 
    Virginia's  nonagricultural  employment  figures  also  mirror  the national
economy. During the  period 1983-1990, the  Commonwealth substantially  outpaced
the  nation in  growth of nonagricultural  employment, with  4.1 percent average
annual growth compared to  2.8 percent nationally; however,  the trend line  for
both  has been flat since 1990. For  the period 1985-1990, the Commonwealth went
ahead of the South Atlantic region, but  was hit harder during the recession  in
1990. Since then, the region has outperformed the Commonwealth.
 
    With  respect to unemployment, Virginia's unemployment rate has consistently
been below that of the nation. For the decade of 1980 to 1990, the  differential
has  been two percentage  points, although it decreased  to below one percentage
point in  1991 and  1992. For  the last  month of  FY 1993,  the  Commonwealth's
unemployment rate was 5.3 percent, compared to the national rate of 7.1 percent.
 
                                       20
<PAGE>
    Employment  trends in  Virginia are  varied from  sector to  sector and from
region to region. For example, an overall increase of 0.8 percent in FY 1993 was
driven by modest increases in government and service sectors, whereas  wholesale
and  retail  trade  employment  was  flat.  Employment  dropped  in  six  of ten
categories, with mining experiencing the  greatest percent loss at 3.6  percent.
The  service sector  is now  the largest  employer in  Virginia and  mininig and
manufacturing are now at  lower levels than in  1980. All of the  Commonwealth's
MSAs  showed increased  employment from  FY 1992  to FY  1993, ranging  from 0.5
percent to  1.8 percent,  with most  employment increases  being experienced  in
metropolitan areas.
 
    Highest  rates of unemployment are  concentrated in southwest Virginia where
mining jobs  have  been lost  and  the lowest  unemployment  rates are  seen  in
Northern  Virginia where much federally-related  employment is concentrated. Not
suprisingly, there is  great overlap  between areas of  lowest unemployment  and
those of highest per capita income.
 
    The  Commonwealth's recovery has  been hurt by the  defense cutbacks, but so
far the  employment and  output reductions  in the  Commonwealth have  not  been
severe.  Further cuts are anticipated in 1995. Base closing actions in 1993 will
result in a statewide net loss of  7,800 defense related jobs, with the  largest
impact  being  experienced in  Northern  Virginia. The  national  recession, the
overheated construction market in Northern Virginia and the restructuring of the
banking industry have also contributed to the Commonwealth's problems. Even  the
Commonwealth's  export  sector,  whose conspicuous  growth  had  been promising,
reflected disappointing results in 1992, with  a loss of 2.6 percent in  current
dollars, although the Commonwealth's exports have expanded rapidly to most areas
of the world over the past five years, averaging 11.3 percent annually.
 
    The  evidence  of  a  slow  economic  recovery,  coupled  with  major  plant
downsizings as  well  as military  base  closures,  with more  likely  in  1995,
portends  slow growth in the near term.  Additional defense cutbacks in the next
three years may be  very difficult if  the recovery has  not gained momentum  by
then.
 
    The  Commonwealth  of  Virginia  has  historically  operated  on  a fiscally
conservative basis  and is  required  by its  Constitution  to have  a  balanced
biennial  budget. At the end of the June 30, 1993, fiscal year, the General Fund
had an ending fund balance computed on a budgetary cash basis of $331.8 million,
of  which  $942,000  was  in  required  reserves.  $271.2  million  thereof  was
designated for expenditure during the next fiscal year, leaving an undesignated,
unreserved   fund  balance  of  $59.7   million,  the  second  consecutive  such
undesignated fund balance since  1988. Computed on a  modified accrual basis  in
accordance  with  generally  accepted accounting  principles,  the  General Fund
balance at the end of  the fiscal year ended June  30, 1993, was $78.8  million,
compared  with a General Fund balance of minus  $121.8 million at the end of the
fiscal year ended  June 30, 1992.  This is the  first year since  1989 that  the
General  Fund, measured on a  modified accrual basis, has  shown a positive fund
balance.
 
    As of  June  30, 1993,  total  debt  for the  Commonwealth  aggregated  $7.5
billion.  Of  that amount,  $2  billion was  tax-supported.  Outstanding general
obligation debt backed by the full faith and credit of the Commonwealth was $817
million at June  30, 1993.  Of that  amount, $511  million was  also secured  by
revenue producing capital projects.
 
    The   Virginia  Constitution  contains  limits  on  the  amount  of  general
obligation  bonds  which   the  Commonwealth   can  issue.   These  limits   are
substantially  in excess of current levels of outstanding bonds, and at June 30,
1993 would permit an additional total of
 
                                       21
<PAGE>
approximately $5.3 billion  of bonds secured  by revenue-producing projects  and
approximately  $5.50 billion of  unsecured general obligation  bonds for capital
projects, with not  more than approximately  $1.46 billion of  the latter to  be
issued in any four-year period. Bonds which are not secured by revenue-producing
projects must be approved in a State-wide election.
 
    The  Commonwealth of Virginia maintains ratings  of AAA by Standard & Poor's
Corporation and  Aaa by  Moody's  Investors Service  on its  general  obligation
indebtedness,  reflecting  in  part  its  sound  fiscal  management, diversified
economic base  and  low debt  ratios.  There can  be  no assurances  that  these
conditions  will continue. Nor are  these same conditions necessarily applicable
to securities which are not general obligations of the Commonwealth.  Securities
issued  by specific municipalities, governmental  authorities or similar issuers
may be subject  to economic risks  or uncertainties peculiar  to the issuers  of
such securities or the sources from which they are to be paid.
 
VIRGINIA 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.
</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.

ARIZONA INSURED TRUST 33
    
   
    The  Portfolio of Arizona Insured Trust  33 consists of 6 obligations issued
by entities located in Arizona 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: College  and University  Revenue, 1; Electrical  System 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 Arizona
Insured Trust is 23.3  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  28.6% 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 June  10,
1994  and June 13, 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 28.6% 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  Arizona Insured Trust,  less estimated expenses, is  estimated to accrue at
the rate of $.01460 per Unit per day under the semi-annual plan of distribution,
$.01455 per Unit per  day under the quarterly  plan of distribution and  $.01446
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  Arizona 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. Such distribution may
    be more or less than a regular monthly distribution.

TAX STATUS--ARIZONA INSURED TRUST
 
    For a  discussion of  the Federal  tax status  of income  earned on  Arizona
Insured Trust Units, see Section 11.
 
    The  assets of the Trust will consist of interest-bearing obligations issued
by  or  on  behalf  of  the  State  of  Arizona  (the  "State"),  its  political
subdivisions  and authorities (the "Arizona Bonds"), and  by or on behalf of the
government of Puerto  Rico, the  government of Guam,  or the  government of  the
Virgin  Islands (collectively the "Possession  Bonds") (collectively the Arizona
Bonds and Possession Bonds shall be referred to herein as the "Bonds"), provided
the interest on such Bonds is exempt from State income taxes.
 
    In the opinion of Chapman and Cutler counsel to the Sponsor, under  existing
law:
 
        For  Arizona income tax purposes, each Unitholder will be treated as the
    owner of a pro rata portion of the Arizona Insured Trust, and the income  of
    the  Trust therefore will be  treated as the income  of the Unitholder under
    State law.
 
        For Arizona  income  tax  purposes,  interest  on  the  Bonds  which  is
    excludable from Federal gross income and which is exempt from Arizona income
    taxes  when  received  by the  Arizona  Insured  Trust, and  which  would be
    excludable from Federal gross income and exempt from Arizona income taxes if
    received directly  by a  Unitholder, will  retain its  status as  tax-exempt
    interest  when received by the Arizona  Insured Trust and distributed to the
    Unitholders.
 
        To the extent that interest derived from the Arizona Insured Trust by  a
    Unitholder  with  respect  to the  Bonds  is excludable  from  Federal gross
    income, such interest will not be subject to Arizona income taxes.
 
        Each Unitholder will receive taxable gain or loss for Arizona income tax
    purposes when Bonds held in the  Arizona Insured Trust are sold,  exchanged,
    redeemed or paid at maturity, or when the Unitholder redeems or sells Units,
    at  a price that differs from original  cost as adjusted for amortization of
    Bond discount or premium  and other basis  adjustments, including any  basis
    reduction  that may be required to reflect a Unitholder's share of interest,
    if any,  accruing on  Bonds  during the  interval between  the  Unitholder's
    settlement date and the date such Bonds are delivered to the Arizona Insured
    Trust, if later.
 
        Amounts paid by the Insurer under an insurance policy or policies issued
    to the Trust, if any, with respect to the Bonds in the Trust which represent
    maturing  interest  on defaulted  obligations held  by  the Trustee  will be
    exempt from State income taxes if,
 
                                       26
<PAGE>
    and to the same extent as, such  interest would have been so exempt if  paid
    by the issuer of the defaulted obligations.
 
        Arizona law does not permit a deduction for interest paid or incurred on
    indebtedness incurred or continued to purchase or carry Units in the Arizona
    Insured Trust, the interest on which is exempt from Arizona income taxes.
 
        Neither  the Bonds  nor the  Units will  be subject  to Arizona property
    taxes, sales tax or use tax.
 
ECONOMIC FACTORS--ARIZONA
 
    GENERAL ECONOMIC  CONDITIONS.   The following  brief summary  regarding  the
economy  of  Arizona is  based upon  information  drawn from  publicly available
sources and  is included  for the  purpose of  providing the  information  about
general  economic conditions that may  or may not affect  issuers of the Arizona
Bonds. The  Sponsor  has  not  independently verified  any  of  the  information
contained  in such publicly  available documents. Arizona  is the nation's sixth
largest state  in  terms of  area.  Arizona's main  economic/employment  sectors
include  services, tourism  and manufacturing.  Mining and  agriculture are also
significant, although  they  tend  to  be more  capital  than  labor  intensive.
Services  is the single largest economic sector. Many of these jobs are directly
related to tourism.
 
    According  to  Arizona  economic  indicators  released  as  of  June   1992,
unemployment  figures show 7.2  percent of Arizona's  population are unemployed,
compared to  a national  level of  7.5 percent  unemployment at  the same  time.
Maricopa  County reported 6.1 percent unemployment  and Pima County reported 5.0
percent unemployment. Significant employers in the state include the government,
the service industry and the trade  industry. Building permits were down in  all
areas  of the state  except for Pima  County. In addition,  home sales were down
approximately 28 percent  from the  previous year,  and retail  sales were  down
approximately 7 percent from the previous year.
 
    On  June 27, 1991,  America West Airlines filed  a Chapter 11 reorganization
petition in bankruptcy. America West was at one time the sixth largest  employer
in  Maricopa County, employing  approximately 10,000 persons  within the county,
and 15,000  nationwide.  The  airline  now  employs  close  to  7,000  employees
nationwide.  The effect of the America West bankruptcy on the state economy and,
more particularly, the Phoenix economy, is uncertain.
 
    Similarly, jobs will  be lost  by the  anticipated closing  of Williams  Air
Force  Base in Chandler, Arizona, in 1993.  Williams Air Force Base was selected
as one of the military installations to  be closed as a cost-cutting measure  by
the  Defense Base Closure and Realignment Commission, whose recommendations were
subsequently  approved  by  the  President  and  the  United  States  House   of
Representatives.  Williams Air Force Base  injects approximately $340 million in
the local economy annually, and employs 1,851 civilians.
 
    In 1986, the value of Arizona real estate began a steady decline, reflecting
a market  which had  been overbuilt  in  the previous  decade with  a  resulting
surplus  of  completed  inventory.  This  decline  adversely  affected  both the
construction  industry  and  those  Arizona  financial  institutions  which  had
aggressively  pursued many  facets of real  estate lending. In  the near future,
Arizona's financial institutions are likely  to continue to experience  problems
until  the  excess  inventories  of commercial  and  residential  properties are
absorbed. The problems  of the  financial institutions  have adversely  affected
employment  and  economic activity.  Longer-term  prospects are  brighter, since
population growth is still strong by  most standards, and Arizona's climate  and
tourist  industry still continue to stimulate  the state's economy. However, the
previously robust pace of growth by  financial institutions is not likely to  be
repeated over an extended period.
 
    BUDGETARY  PROCESS.  Arizona operates on a  fiscal year beginning July 1 and
ending June 30. Fiscal year 1992 refers to the year ending June 30, 1992.
 
                                       27
<PAGE>
    Total General Fund revenues of $3.4 billion were expected during fiscal year
1992. Approximately 45.8%  of this  budgeted revenue  comes from  sales and  use
taxes,  38.9% from  income taxes (both  individual and corporate)  and 5.2% from
property taxes.  All taxes  total  approximately $3.3  billion,  or 93%  of  the
General  Fund revenues. Non-tax  revenue includes items such  as income from the
state lottery, licenses, fees and  permits, and interest. Lottery income  totals
approximately 34.6% of non-tax revenue.
 
    For  fiscal year 1992,  the budget called for  expenditures of $2.7 billion.
These expenditures fell into the following major categories: education  (51.3%),
health  and welfare  (29.3%), protection  and safety  (9.8%), general government
(7.6%) and  inspection  and  regulation, natural  resources  and  transportation
(2.0%).  The State's general fund revenues for  fiscal year 1993 are budgeted at
$3.6 billion  and total  general  fund expenditures  for  fiscal year  1993  are
budgeted  at $3.65 billion.  Fiscal year 1993's  proposed expenditures fall into
the following major categories: education  (55.4%), health and welfare  (27.8%),
protection  and  safety (9.0%),  general  government (6.2%)  and  inspection and
regulation and natural resources (1.6%).
 
    Most or all of the Bonds of the Arizona Insured Trust are not obligations of
the State of Arizona, and  are not supported by  the State's taxing powers.  The
particular  source of payment and security for  each of the Bonds is detailed in
the instruments themselves and  in related offering materials.  There can be  no
assurances,  however, with respect to whether  the market value or marketability
of any of the Bonds issued by an entity other than the State of Arizona will  be
affected  by the  financial or  other condition  of the  State or  of any entity
located within the  State. In addition,  it should  be noted that  the State  of
Arizona,  as well as counties,  municipalities, political subdivisions and other
public authorities of the state, are subject to limitations imposed by Arizona's
constitution with respect to ad valorem taxation, bonded indebtedness and  other
matters.  For  example, the  state  legislature cannot  appropriate  revenues in
excess of 7% of the total personal income of the state in any fiscal year. These
limitations may  affect the  ability  of the  issuers  to generate  revenues  to
satisfy their debt obligations.
 
    Although  most  of  the  Bonds  in the  Arizona  Insured  Trust  are revenue
obligations of local governments  or authorities in the  State, there can be  no
assurance  that the  fiscal and economic  conditions referred to  above will not
affect the market  value or marketability  of the  Bonds or the  ability of  the
respective obligors to pay principal of and interest on the Bonds when due.
 
    The  State of Arizona was recently sued  by four named school districts with
an additional fifty school districts within the state participating in the suit,
claiming that the state's funding system  for school buildings and equipment  is
unconstitutional. The lawsuit does not seek damages, but requests that the court
order the State to create a new financing system that sets minimum standards for
buildings  and furnishings  that apply  on a  statewide basis.  A superior court
ruling has upheld the  constitutionality of the  State's school funding  system.
This  decision has been appealed and is currently in the State Court of Appeals.
It is  unclear, at  this time,  what affect  any judgment  would have  on  state
finances  or school district budgets. The  U.S. Department of Education recently
determined that  Arizona's  educational  funding system  did  not  meet  federal
requirements of equity. This determination could mean a loss in federal funds of
approximately $50 million.
 
    Certain  other circumstances are relevant to the market value, marketability
and payment of any hospital and health care revenue bonds in the Arizona Insured
Trust. The Arizona Legislature attempted unsuccessfully in its 1984 regular  and
special  sessions to  enact legislation designed  to control  health care costs,
ultimately adopting  three  referenda  measures placed  on  the  November,  1984
general  election ballot which in various ways would have regulated hospital and
health care  facility  expansions, rates  and  revenues.  At the  same  time,  a
coalition  of  Arizona  employers  proposed  two  initiatives  voted  on  in the
November, 1984 general  election which would  have created a  State agency  with
power  to  regulate  hospital  and health  care  facility  expansions  and rates
generally. All of these referenda and
 
                                       28
<PAGE>
initiative propositions  were  rejected by  the  voters in  the  November,  1984
general   election.  Pre-existing  State   certificate-of-need  laws  regulating
hospital and health care facilities' expansions and services have expired, and a
temporary  moratorium  prohibiting  hospital  bed  increases  and  new  hospital
construction  projects and a  temporary freeze on hospital  rates and charges at
June, 1984 levels has also expired.  Because of such expirations and  increasing
health  care costs, it is  expected that the Arizona  Legislature will at future
sessions continue to attempt to adopt legislation concerning these matters.  The
effect  of any such legislation  or of the continued  absence of any legislation
restricting hospital bed increases and limiting new hospital construction on the
ability of Arizona hospitals and other health care providers to pay debt service
on their revenue bonds cannot be determined at this time.
 
    Arizona does not participate in the federally administered Medicaid program.
Instead, the state  administers an alternative  program, AHCCCS, which  provides
health   care  to   indigent  persons  meeting   certain  financial  eligibility
requirements, through managed  care programs.  In fiscal year  1992, AHCCCS  was
financed  approximately 52.7% by federal funds,  33.1% by state funds, and 13.6%
by county funds.
 
    Under state  law,  hospitals  retain  the  authority  to  raise  rates  with
notification  and review  by, but  not approval  from, the  Department of Health
Services. Hospitals  in Arizona  have experienced  profitability problems  along
with  those in other states. At least two Phoenix based hospitals have defaulted
on or reported difficulties  in meeting their bond  obligations during the  past
three years.
 
    Insofar as tax-exempt Arizona public utility pollution control revenue bonds
are concerned, the issuance of such bonds and the periodic rate increases needed
to  cover operating  costs and  debt service  are subject  to regulation  by the
Arizona Corporation Commission,  the only significant  exception being the  Salt
River  Project Agricultural Improvement  and Power District  which, as a Federal
instrumentality, is  exempt from  rate  regulation. On  July 15,  1991,  several
creditors of Tucson Electric Power Company ("Tucson Electric") filed involuntary
petitions  under Chapter 11 of the U.S. Bankruptcy Code to force Tucson Power to
reorganize under the supervision of the bankruptcy court. On December 31,  1991,
the  Bankruptcy Court approved the utility's motion to dismiss the July petition
after five months of negotiations between  Tucson Electric and its creditors  to
restructure  the utility's debts and other obligations. In December 1992, Tucson
Electric announced that it had completed its financial restructuring. In January
1993, Tucson  Electric  asked the  Arizona  Corporation Commission  for  a  9.6%
average  rate increase. Tucson Electric  serves approximately 270,000 customers,
primarily in  the Tucson  area. Inability  of any  regulated public  utility  to
secure  necessary rate  increases could  adversely affect,  to an indeterminable
extent, its ability to pay debt service on its pollution control revenue bonds.
 
ARIZONA 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
 
                                       29

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 dates  range from June  23, 1994 to
  June 28, 1994. Contracts relating to Bonds with delivery dates after the  date
  of   settlement  for  purchase   made  on  the   Date  of  Deposit  constitute
  approximately 29% of the aggregate principal amount of the Trust. (See Section

FLORIDA INSURED TRUST 192
    
   
    The  Portfolio of Florida Insured Trust 192 consists of 6 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. 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,  2; Health  Care Facility  Revenue,  1;
Combination  Utility 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  Florida
Insured  Trust is 26.6  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 14.3% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 14.4% 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 the sale of electric energy.
 
    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 June 10,
1994 and June 13, 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  Florida Insured Trust,  less estimated expenses, is  estimated to accrue at
the rate of $.01430 per Unit per day under the semi-annual plan of distribution,
$.01425 per Unit per  day under the quarterly  plan of distribution and  $.01416
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.
 
        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.
 
                                       33
<PAGE>
        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 most  populous state in  the
U.S.  The State has grown dramatically since then and as of April 1, 1992, ranks
fourth with an estimated  population of 13.4  million. Florida's attraction,  as
both a growth and retirement state, has kept net migration fairly steady with an
average of 252,200 new residents a year from 1982 through 1991. The U.S. average
population  increase since  1982 is about  1% annually,  while Florida's average
annual rate  of increase  is about  2.8%. 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 1982, the prime working  age population (18-44) has grown  at
an  average  annual rate  of  3.3%. The  share  of Florida's  total  working age
population (18-59) to total State population is approximately 54%. 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 has tracked  closely with the national  average and has  tracked
above  the southeast. From 1983 through 1992, the State's real per capita income
rose at an average of 5.4% per  year, while the national real per capita  income
increased at an average of 5.5% 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 1992 was 61% of total personal income, while
a similar  figure  for  the nation  for  1990  was 72%.  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 1992 of $19,947 was slightly below
the national  average  of  $19,841  and significantly  ahead  of  that  for  the
southeast United States, which was $17,661. Real personal income in the State is
estimated  to  increase 5.5%  in  1993-94 and  4.7% in  1994-95.  By the  end of
1994-95, real personal income  per capita in the  State is projected to  average
6.7% higher than its 1992-93 level.
    
   
    EMPLOYMENT.   Since 1980, the State's job  creation rate is almost 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.  In recent years,
however, as the  State's economic  growth has  slowed from  its previous  highs,
    
 
                                       34
<PAGE>
   
the  State's  unemployment  rate has  tracked  above the  national  average. The
average rate in Florida since 1980 has  been 6.5% while the national average  is
7.1%.  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
8.2% during  1992. As  of  January 1994,  the  Organization estimates  that  the
unemployment rate will be 6.7% for 1993-94 and 6.1% in 1994-95.
    
   
    The rate of job creation in Florida's manufacturing sector has exceeded that
of the U.S. From the beginning of 1980 through 1993, the State added over 50,000
new  manufacturing jobs,  an 11.7%  increase. During  the same  period, national
manufacturing employment declined ten out of  the fourteen years, for a loss  of
2,977,000 jobs.
    
   
    Total non-farm employment in Florida is expected to increase 2.7% in 1993-94
and  rise  3.8% in  1994-95.  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's should experience an increase of
3.9% in 1993-94, while growing 4.9% in 1994-95. Trade is expected to expand 2.2%
in 1994  and  3.4% in  1995.  The service  sector  is now  the  State's  largest
employment category.
    
 
   
    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 1993 the share had edged downward to 5.0%. 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 8.5%  of total U.S. housing  starts in 1993 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 11.0%  of the  U.S.'s total
annual starts, and  since 1980,  total housing  starts have  averaged 156,450  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 250,000  range annually  throughout 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.
 
   
    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  1993-94 are  projected to  reach  a
combined  level  of 118,000,  and to  increase to  134,300 next  year. Lingering
recessionary effects on consumers and tight  credit are some 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. Low interest rates  and
pent  up  demand  combined  with improved  consumer  confidence  should  lead to
improved housing  starts.  The  construction figures  above  include  additional
housing   starts  as  a  result  of   destruction  by  Hurricane  Andrew.  Total
construction expenditures  are  forecasted  to  increase  15.6%  this  year  and
increase 13.3% next year.

    The   State  has  continuously   been  dependent  on   the  highly  cyclical
construction and  construction  related  manufacturing  industries.  While  that
dependency  has  decreased, the  State is  still  somewhat at  the mercy  of the
construction and construction related manufacturing industries. The construction
industry is driven to a great extent by the State's rapid growth in  population.
There  can be no  assurance that population growth  will continue throughout the
1990's in which case  there could be  an adverse impact  on the State's  economy
through  the loss of  construction and construction  related manufacturing jobs.
Also, while interest rates remain low  currently, an increase in interest  rates
could  significantly adversely impact  the financing of  new construction within
the State, thereby adversely impacting  unemployment and other economic  factors
within  the State. In addition, available  commercial office space has tended to
remain high over the past few years.  So long as this glut of commercial  rental
space  continues, construction  of this  type of  space will  likely continue to
remain slow.
    
   
    TOURISM.    Tourism  is  one  of  the  State's  most  important  industries.
Approximately  40.9 million tourists  visited the State in  1992, as reported by
the Florida Department of  Commerce. In terms of  business activities and  state
tax  revenues, tourists in Florida in  1992 represented an estimated 4.5 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.  The
dollar's  depreciation  has  enhanced  the  State's  tourism  industry.  Tourist
arrivals are expected to  decline by almost two  percent this year, but  recover
next  year with  5.0% growth.  Tourist arrivals  to Florida  by air  and car are
expected to diverge  from each other,  air decreasing 5.6%  and auto  increasing
1.6%.  By the end of the State's  current fiscal year, 41.0 million domestic and
international tourists  are  expected to  have  visited the  State.  In  1994-95
tourist arrivals should approximate 43.0 million.
    
   
    REVENUES  AND EXPENSES.  Estimated fiscal  year 1993-94 General Revenue plus
Working Capital funds available  to the State total  $13,582.7 million, an  8.4%
increase  over 1992-93.  This reflects  a transfer  of $190  million, out  of an
estimated $220.0 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, $12,943.5 million of  that is Estimated  Revenues
(excluding  the Hurricane Andrew  impact), which represents  an increase of 7.3%
over the previous  year's Estimated  Revenues. With  effective General  Revenues
plus  Working  Capital Fund  appropriations  at $13,276.9  million, unencumbered
reserves at the end of 1993-94 are estimated at $305.8 million. Estimated fiscal
year  1994-95  General  Revenue  plus  Working  Capital  Funds  available  total
$14,293.5 million, a 5.2% increase over 1993-94. This amount reflects a transfer
of  $159.0  million  in  non-recurring  revenue due  to  Hurricane  Andrew  to a
hurricane relief fund.  The $13,877.2 million  in Estimated Revenues  (excluding
Hurricane  Andrew impact) represent an increase of 7.2% 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  1992-93, approximately  62%  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, intangible personal  property tax  and beverage tax
amounted to 68%,  7%, 4% and  4%, respectively, of  total General Revenue  Funds
available  during fiscal 1992-93. In that same year, expenditures for education,
health and welfare, and  public safety amounted to  approximately 49%, 30%,  and
11%, 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
 
                                       36
<PAGE>
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 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 applicable  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,
1993,  sales and use tax receipts (exclusive  of the tax on gasoline and special
fuels) totalled $9,426.0 million, an increase of 12.5% over fiscal year 1991-92.
 
    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 $442.2 million in fiscal year ending June 30, 1993. Alcoholic
beverage tax  receipts  increased  1.6%  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, 1993,  receipts from this  source were $846.6  million, an increase  of
5.6% from fiscal year 1991-92.
 
    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  $639.0 million  during fiscal  year 1992-93,  a
27.0%  increase from the previous fiscal year. Beginning in fiscal year 1992-93,
71.29% of these taxes is to be deposited to the General Revenue Fund.
 
   
    The State  imposes  a gross  receipts  tax  on electric,  natural  gas,  and
telecommunications  services. All  gross receipt  utilities tax  collections are
credited to the State's Public Education  Capital Outlay and Debt Service  Trust
Fund. In fiscal year 1992-93, this amounted to $447.9 million.
    
   
    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  1992-93,  total  intangible  personal
property  tax collections  were $783.4  million, a  33% increase  over the prior
year. Of the tax proceeds, 66.5% is distributed to the General Revenue Fund.
    
 
    The State's severance tax taxes oil, gas and sulphur production, as well  as
the severance of phosphate rock and other solid minerals. Total collections from
severance  taxes total $64.5 million during  fiscal year 1992-93, down 4.0% from
the previous year. Currently  60% of this amount  is transferred 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  1992-93  lottery ticket  sales  totalled  $2.13  billion,
providing education with approximately $810.4 million.
 
   
    DEBT-BALANCED  BUDGET REQUIREMENT.  At the end of fiscal 1993, approximately
$5.61 billion in principal amount of debt  secured by the full faith and  credit
of  the State was outstanding. In addition, since July 1, 1993, the State issued
about $873.0 million in principal amount of full faith and credit bonds.
    
 
                                       37

    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, 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.
 
    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 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  June 24,  1994. Contracts
  relating to  Bonds  with delivery  dates  after  the date  of  settlement  for
  purchase  made  on the  Date of  Deposit constitute  approximately 15%  of the

NEW YORK INSURED TRUST 218
    
   
    The Portfolio of New York Insured Trust 218 consists of 7 obligations issued
by  entities located in New York. 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: Dedicated-Tax Supported Revenue, 1; College and University Revenue,
1; Municipal Lease 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 New York
Insured Trust is 23.1  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  28.3% of the  aggregate principal amount of  the Bonds in the
Trust (accounting for approximately 28.1% 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  28% of  the aggregate  principal amount  of the  Bonds in the
Trust consists of municipal lease obligations.
 
    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 June 13, 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 York Insured Trust, less estimated  expenses, is estimated to accrue at
the rate of $.01520 per Unit per day under the semi-annual plan of distribution,
$.01515 per Unit per  day under the quarterly  plan of distribution and  $.01506
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.

(1)  The first distribution will be paid to all Unitholders,  regardless of the distribution plan selected. Such distribution may
    be more or less than a regular monthly distribution.
(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  4-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 or as fees and expenses increase or decrease.
 
TAX STATUS--NEW YORK INSURED TRUST
 
    For a discussion  of the Federal  tax status  of income earned  on New  York
Insured Trust Units, see Section 11.
 
    In  the opinion of Edwards & Angell,  special counsel for the Series for New
York tax matters, under existing law:
 
        Interest  on  obligations  issued  by   New  York  State,  a   political
    subdivision  thereof, 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
    ("New York Obligations"), which would be  exempt from New York State or  New
    York  City personal  income tax if  directly received by  a Unitholder, will
    retain its  status as  tax-exempt interest  when received  by the  New  York
    Insured Trust (the "Trust") and distributed to such Unitholder.
 
        Interest  (less amortizable premium, if any) derived from the Trust by a
    resident of New  York State  (or New York  City) in  respect of  obligations
    issued  by states other than New York (or their political subdivisions) will
    be subject to New York State (or New York City) personal income tax.
 
        A Unitholder who is a resident of New York State (or New York City) will
    be subject to New  York State (or  New York City)  personal income tax  with
    respect  to gains realized  when New York  Obligations held in  the New York
    Insured  Trust  are  sold,  redeemed  or  paid  at  maturity  or  when   the
    Unitholder's  Units are sold or redeemed;  such gain will equal the proceeds
    of sale, redemption or payment less the tax basis of the New York Obligation
    or Unit (adjusted to reflect (a) the amortization of premium or discount, if
    any, on New York Obligations held  by the Trust, (b) accrued original  issue
    discount,  with respect to each  New York Obligation which,  at the time the
    New York Obligation  was issued, had  original issue discount,  and (c)  the
    deposit of New York Obligations with accrued interest in the Trust after the
    Unitholder's settlement date).
 
        Interest  or gain from  the Trust derived  by a Unitholder  who is not a
    resident of New York  State (or New  York City) will not  be subject to  New
    York State (or New York City)
 
                                       42
<PAGE>
    personal  income tax, unless the Units  are property employed in a business,
    trade, profession or occupation  carried on in New  York State (or New  York
    City).
 
        In  the case  of the  Trust, amounts  paid under  the insurance policies
    representing maturing interest on defaulted New York Obligations held by the
    Trustee in the Trust  will be excludable  from New York  State and New  York
    City  income if, and  to the same  extent as, such  interest would have been
    excludable if paid by the respective issuer.
 
        For purposes of the New  York State and New  York City franchise tax  on
    corporations,  Unitholders which are subject to such tax will be required to
    include in their entire net income any interest or gains distributed to them
    even  though  distributed  in  respect  of  obligations  of  any  state   or
    subdivision thereof including New York.
 
        If borrowed funds are used to purchase Units in the Trust, all (or part)
    of  the interest on  such indebtedness will  not be deductible  for New York
    State and  New  York  City  tax  purposes. The  purchase  of  Units  may  be
    considered  to have been made with borrowed funds even though such funds are
    not directly traceable to the purchase of Units in any New York Trust.
 
ECONOMIC FACTORS--NEW YORK
 
    The Portfolio of the New York  Insured Trust includes obligations issued  by
New  York State  (the "State"), by  its various public  bodies (the "Agencies"),
and/or by other  entities located within  the State, including  the City of  New
York (the "City").
 
    Some of the more significant events and conditions relating to the financial
situation  in New York are summarized below.  This section provides only a brief
summary of the complex factors affecting the financial situation in New York and
is derived  from  sources that  are  generally  available to  investors  and  is
believed  to  be  accurate. It  is  based  in part  on  Official  Statements and
prospectuses issued by, and on other information reported by the State, the City
and the Agencies in connection with the issuance of their respective securities.
 
    There can  be no  assurance that  current or  future statewide  or  regional
economic  difficulties, and  the resulting impact  on State  or local government
finances generally,  will not  adversely affect  the market  value of  New  York
Municipal  Obligations held  in the  portfolio of  the Trust  or the  ability of
particular obligors to make timely payments of debt service on (or relating  to)
those obligations.
 
    (1)  THE STATE: The State has historically been one of the wealthiest states
in the nation.  For decades, however,  the State economy  has grown more  slowly
than  that of  the nation  as a  whole, gradually  eroding the  State's relative
economic  affluence.  Statewide,  urban  centers  have  experienced  significant
changes involving migration of the more affluent to the suburbs and an influx of
generally  less affluent residents. Regionally,  the older Northeast cities have
suffered because of the relative success that the South and the West have had in
attracting  people  and  business.  The  City  has  also  had  to  face  greater
competition  as  other  major  cities  have  developed  financial  and  business
capabilities  which  make  them  less  dependent  on  the  specialized  services
traditionally available almost exclusively in the City.
 
    The  State has  for many years  had a very  high state and  local tax burden
relative to other states. The burden of State and local taxation, in combination
with the many other causes of regional economic dislocation, has contributed  to
the  decisions of  some businesses and  individuals to relocate  outside, or not
locate within, the State.
 
    SLOWDOWN OF REGIONAL  ECONOMY. A national  recession commenced in  mid-1990.
The  downturn  continued  throughout the  State's  1990-91 fiscal  year  and was
followed by a period of weak economic growth during the 1991 calendar year.  For
calendar  year 1992,  the national economy  continued to recover,  although at a
rate below all  post-war recoveries. For  calendar year 1993,  the economy  grew
faster    than   in    1992,   but    still   at    a   very    moderate   rate,
 
                                       43
<PAGE>
as compared  to  other  recoveries.  Moderate economic  growth  is  expected  to
continue  in calendar year 1994 at a slightly faster rate than in 1993. Economic
recovery started considerably later in the State  than in the nation as a  whole
due  in  part  to the  significant  retrenchment  in the  banking  and financial
services industries,  downsizing  by  several major  corporations,  cutbacks  in
defense  spending,  and an  oversupply of  office buildings.  Many uncertainties
exist in forecasts of both the national and State economies and there can be  no
assurance  that the State economy will perform at a level sufficient to meet the
State's projections of receipts and disbursements.
 
    1994-95 FISCAL YEAR. The Governor presented the recommended Executive Budget
for the 1994-95 fiscal year on January  18, 1994 and amended it on February  17,
1994.  the Recommended 1994-95 State Financial  Plan projects a balanced General
Fund, receipts and transfers  from other funds at  $33.422 billion (including  a
projected  $339 million surplus anticipated for the State's 1993-94 fiscal year)
and disbursements and transfers to other funds at $33.399 billion.
 
    The recommended 1994-95  Executive Budget  includes tax  and fee  reductions
($210  million), retention of revenues currently received, primarily by deferral
of a  scheduled  personal  income  tax  rate  reduction  ($1.244  billion),  and
additional  increases to miscellaneous revenue  sources ($237 million). No major
additional programs are recommended other than a $198 million increase in school
aid, $185 million in Medicaid  cost-containment initiatives and $110 million  in
local government Medicaid costs to be assumed by the State.
 
    There  can  be  no  assurance  that the  State  Legislature  will  enact the
Executive  Budget  as  proposed,  nor  can  there  be  any  assurance  that  the
Legislature will enact a budget for the State's 1994-95 fiscal year prior to its
commencement.  A delay in  its enactment may  negatively affect certain proposed
actions and reduce projected savings.
 
    1993-94 FISCAL YEAR. The  1993-94 State Financial Plan  issued on April  16,
1993  projected General Fund receipts and  transfers from other funds at $32.367
billion and disbursements and  transfers to other funds  at $32.300 billion.  In
comparison to the Governor's recommended Executive Budget for the 1993-94 fiscal
year,  as  revised  on  February  18, 1993,  the  1993-94  State  Financial Plan
reflected increases in both  receipts and disbursements in  the General Fund  of
$811 million.
 
    The  1993-94 State Financial Plan was last  revised on January 18, 1994. The
State projects a surplus  of $299 million, as  the result of developments  which
positively  impacted upon receipts  and disbursements. In  the revised Plan, the
State announced its intention to pay  a 53rd weekly Medicaid payment,  estimated
at $120 million, and to add $82 million to a reserve fund for contingencies.
 
    On  January 21, 1994, the State entered into a settlement with Delaware with
respect to STATE OF DELAWARE V. STATE  OF NEW YORK, which is discussed below  at
STATE  LITIGATION. The State made an immediate $35 million payment and agreed to
make a $33 million  annual payment in  each of the next  five fiscal years.  The
State  has not settled with other parties to the litigation and will continue to
incur litigation expenses as to those claims.
 
    On November  16, 1993,  the Court  of Appeals,  the State's  highest  court,
affirmed  the  decision  of  a  lower court  in  three  actions,  which declared
unconstitutional State actuarial funding methods for determining State and local
contributions to the State employee  retirement system. Following the  decision,
the  State Comptroller  developed a  plan to  phase in  a constitutional funding
method and to restore prior funding levels of the retirement systems over a four
year period. The plan is  not expected to require  the State to make  additional
contributions  with respect  to the  1993-94 fiscal  year nor  to materially and
adversely affect the State's financial condition thereafter. Through fiscal year
1998-99, the State expects to
 
                                       44
<PAGE>
contribute $643  million more  to  the retirement  plans  than would  have  been
required under the prior funding method.
 
    FUTURE  FISCAL YEARS. There can be no assurance that the State will not face
substantial potential budget  gaps in  the future resulting  from a  significant
disparity  between tax revenues  projected from a  lower recurring receipts base
and the  spending required  to maintain  State programs  at current  levels.  To
address   any  potential  budgetary  imbalance,  the  State  may  need  to  take
significant actions to align recurring receipts and disbursements.
 
    INDEBTEDNESS. As of December 31, 1993,  the total amount of long-term  State
general obligation debt authorized but unissued stood at $2.3 billion. As of the
same  date, the State had approximately $5.0 billion in general obligation bonds
and $2.94 million  of Bond Anticipation  Notes ("BANS"). The  State issued  $850
million  in tax and revenue anticipation notes  ("TRANS") on May 4, all of which
matured on December 31, 1993. The State does not project the need to issue TRANS
during the State's 1994-95 fiscal year.
 
    The State anticipates that  its borrowings for  capital purposes during  the
State's  1994-95 fiscal year will consist  of $413 million in general obligation
bonds and BANS.  The projection of  the State regarding  its borrowings for  the
1994-95  fiscal  year  may  change  if  actual  receipts  fall  short  of  State
projections or if other circumstances require.
 
    In  June  1990,  legislation  was  enacted  creating  the  "New  York  Local
Government  Assistance  Corporation"  ("LGAC"),  a  public  benefit  corporation
empowered to  issue long-term  obligations  to fund  certain payments  to  local
governments  traditionally funded through the State's annual seasonal borrowing.
As of February 28, 1994,  LGAC has issued its bonds  to provide net proceeds  of
$3.7  billion. The Governor has recommended  the issuance of additional bonds to
provide net proceeds of $315 million during the State's 1994-95 fiscal year.
 
    The Legislature  passed  a  proposed constitutional  amendment  which  would
permit  the State subject to certain restrictions to issue revenue bonds without
voter referendum. Among the restrictions proposed  is that such bonds would  not
be  backed by the  full faith and credit  of the State.  The Governor intends to
submit changes to the proposed  amendment, which before becoming effective  must
be passed again by the next separately-elected Legislature and approved by voter
referendum  at a  general election.  The earliest  such an  amendment could take
effect would be in November 1995.
 
    RATINGS.  The $850 million in TRANS  issued by the State in April 1993  were
rated  SP-1-Plus by  S&P on April  26, 1993, and  MIG-1 by Moody's  on April 23,
1993, which represents the highest ratings given by such agencies and the  first
time  the State's  TRANS have  received these ratings  since its  May 1989 TRANS
issuance. Both  agencies  cited  the  State's  improved  fiscal  position  as  a
significant factor in the upgrading of the April 1993 TRANS.
 
    Moody's  rating of the State's general obligation  bonds stood at A on April
23, 1993, and S&P's rating stood at A- with a stable outlook on April 26,  1993,
an  improvement from  S&P's negative  outlook prior  to April  1993. Previously,
Moody's lowered its rating to A on June 6, 1990, its rating having been A1 since
May 27, 1986. S&P  lowered its rating from  A to A- on  January 13, 1992.  S&P's
previous ratings were A from March 1990 to January 1992, AA- from August 1987 to
March 1990 and A+ from November 1982 to August 1987.
 
    Moody's  maintained  its  A  rating  and  S&P  continued  its  A-  rating in
connection with the State's issuance of $224.1 million of its general obligation
bonds in March 1994.
 
    (2) THE  CITY AND  THE MUNICIPAL  ASSISTANCE CORPORATION  ("MAC"): The  City
accounts  for approximately 41%  of the State's  population and personal income,
and the City's financial health affects the State in numerous ways.
 
    In response to the City's fiscal crisis in 1975, the State took a number  of
steps  to assist the City in returning to fiscal stability. Among other actions,
the State Legislature (i) created
 
                                       45
<PAGE>
MAC to assist with long-term financing for the City's short-term debt and  other
cash  requirements  and  (ii) created  the  State Financial  Control  Board (the
"Control Board") to  review and approve  the City's budgets  and City  four-year
financial  plans (the financial plans also  apply to certain City-related public
agencies (the "Covered Organizations")).
 
    Over the past  three years,  the rate  of economic  growth in  the City  has
slowed  substantially, and  the City's  economy is  currently in  recession. The
Mayor  is  responsible  for  preparing  the  City's  four-year  financial  plan,
including  the City's  current financial plan.  The City  Comptroller has issued
reports concluding that the recession of the City's economy will be more  severe
and last longer than is assumed in the financial plan.
 
    FISCAL  YEAR 1993 AND 1994-1997 FINANCIAL PLAN.  The City's 1993 fiscal year
results are  projected to  be  balanced in  accordance with  generally  accepted
accounting  principles  ("GAAP"). The  City  was required  to  close substantial
budget gaps  in its  1990,  1991 and  1992 fiscal  years  in order  to  maintain
balanced operating results.
 
    On  August 10, 1993, the City adopted and submitted to the Control Board its
Financial Plan for fiscal  years 1994-1997, which  was subsequently modified  on
November  23, 1993. As modified  in November 1993, the  Plan projects a balanced
budget for fiscal year 1994 based upon revenues of $31.585 billion, and projects
budget gaps of $1.7 billion, $2.5 billion and $2.7 billion in fiscal years  1995
through 1997, respectively.
 
    During  December  1993, a  three-member panel  appointed  by the  Mayor, the
Office of  the State  Deputy  Comptroller and  the  Control Board,  each  issued
reports  that were critical  of the City's 1994-1996  Financial Plan. While each
report noted  improvement in  the  outlook for  fiscal  year 1994,  the  reports
indicated  that the  budget gap for  fiscal year 1995  could be as  much as $450
million higher than projected and that the budget gap might continue to increase
in later years to as  much as $1.5 billion  above current projections by  fiscal
year 1997. Recommendations included addressing the City's tax and cost structure
to maximize revenues on a recurring basis and minimize expenditures, a review of
capital   spending  plans,   service  cuts,  productivity   gains  and  economic
development measures.
 
    On February  2,  1994,  the  Mayor proposed  further  modifications  to  the
1994-1997  Financial Plan. The Mayor's proposed  Plan projects a balanced budget
for fiscal  year 1994,  assuming revenues  of $31.735  billion, and  includes  a
reserve  of $198  million. The  proposed modification  projects budget  gaps for
fiscal years 1995, 1996 and 1997 of $2.3 billion, $3.2 billion and $3.3 billion,
respectively. The  Mayor identified  $2.2 billion  in gap  closing measures  for
fiscal  year 1995. Implementation of these measures will require the cooperation
of  municipal  labor  unions,  the  City  Council  and  the  State  and  Federal
governments.  The Mayor's proposal  includes a tax  reduction program which will
have a financial impact on later years.
 
    Given the foregoing factors,  there can be no  assurance that the City  will
continue  to maintain  a balanced  budget, or  that it  can maintain  a balanced
budget without additional tax or other  revenue increases or reductions in  City
services, which could adversely affect the City's economic base.
 
    Pursuant  to State law, the City prepares a four-year annual financial plan,
which is reviewed and revised on a quarterly basis and which includes the City's
capital, revenue and  expense projections. The  City is required  to submit  its
financial  plans to review bodies, including the Control Board. If the City were
to experience certain adverse financial circumstances, including the  occurrence
or  the  substantial likelihood  and imminence  of the  occurrence of  an annual
operating deficit of more than $100 million or the loss of access to the  public
credit   markets  to   satisfy  the   City's  capital   and  seasonal  financial
requirements, the  Control Board  would be  required by  State law  to  exercise
certain  powers,  including prior  approval  of City  financial  plans, proposed
borrowings and certain contracts.
 
                                       46
<PAGE>
    The City depends  on the  State for  State aid both  to enable  the City  to
balance  its budget and to meet its  cash requirements. If the State experiences
revenue shortfalls or spending increases beyond its projections during its  1993
fiscal year or subsequent years, such developments could result in reductions in
projected  State aid to  the City. In  addition, there can  be no assurance that
State budgets in future fiscal  years will be adopted  by the April 1  statutory
deadline  and that there will not be adverse effects on the City's cash flow and
additional City expenditures as a result of such delays.
 
    The City projections set  forth in its financial  plan are based on  various
assumptions and contingencies which are uncertain and which may not materialize.
Changes  in major assumptions  could significantly affect  the City's ability to
balance its budget as required by State law and to meet its annual cash flow and
financing requirements. Such assumptions and contingencies include the timing of
any regional  and local  economic recovery,  the absence  of wage  increases  in
excess  of  the  increases assumed  in  its financial  plan,  employment growth,
provision of  State  and  Federal  aid and  mandate  relief,  State  legislative
approval  of future  State budgets, levels  of education expenditures  as may be
required by State  law, adoption of  future City  budgets by the  New York  City
Council,  and  approval  by  the  Governor  or  the  State  Legislature  and the
cooperation of  MAC with  respect  to various  other  actions proposed  in  such
financial plan.
 
    The  City's ability to maintain a  balanced operating budget is dependant on
whether it  can implement  necessary service  and personnel  reduction  programs
successfully.  As discussed above, the City must identify additional expenditure
reductions and revenue sources to achieve balanced operating budgets for  fiscal
years  1994 and  thereafter. Any  such proposed  expenditure reductions  will be
difficult to implement  because of  their size and  the substantial  expenditure
reductions already imposed on City operations in the past two years.
 
    Attaining  a balanced  budget is also  dependent upon the  City's ability to
market its  securities successfully  in the  public credit  markets. The  City's
financing  program  for  fiscal  years 1994  through  1997  contemplates capital
spending of $16.2  billion, which  will be  financed through  issuance of  $10.5
billion  of general  obligation bonds, $4.3  billion of  Water Authority Revenue
Bonds and the balance by Covered Organization obligations, and will be  utilized
primarily to reconstruct and rehabilitate the City's infrastructure and physical
assets  and  to make  capital investments.  A significant  portion of  such bond
financing is used to reimburse the City's general fund for capital  expenditures
already  incurred. In  addition, the  City issues  revenue and  tax anticipation
notes to  finance  its seasonal  working  capital requirements.  The  terms  and
success  of projected  public sales of  City general obligation  bonds and notes
will be subject to prevailing market conditions at the time of the sale, and  no
assurance can be given that the credit markets will absorb the projected amounts
of  public bond and note sales.  In addition, future developments concerning the
City and public  discussion of  such developments, the  City's future  financial
needs  and  other issues  may  affect the  market  for outstanding  City general
obligation bonds  and  notes.  If the  City  were  unable to  sell  its  general
obligation  bonds  and notes,  it would  be prevented  from meeting  its planned
operating and capital expenditures.
 
    FISCAL YEARS 1990,  1991 AND  1992.   The City  achieved balanced  operating
results as reported in accordance with GAAP for the 1992 fiscal year. During the
1990  and 1991 fiscal  years, the City  implemented various actions  to offset a
projected budget  deficit  of $3.2  billion  for  the 1991  fiscal  year,  which
resulted  from declines in City revenue  sources and increased public assistance
needs due to the recession. Such actions included $822 million of tax  increases
and substantial expenditure reductions.
 
    The City is a defendant in a significant number of lawsuits. Such litigation
includes,  but is not limited to,  actions commenced and claims asserted against
the City arising out of
 
                                       47
<PAGE>
alleged constitutional  violations,  torts,  breaches of  contracts,  and  other
violations  of law and condemnation proceedings.  While the ultimate outcome and
fiscal impact,  if  any,  on  the  proceedings  and  claims  are  not  currently
predictable,  adverse determinations  in certain of  them might  have a material
adverse effect upon the City's  ability to carry out  its financial plan. As  of
June  30, 1992, legal claims in excess  of $341 billion were outstanding against
the City for which the City estimated its potential future liability to be  $2.3
billion.
 
    RATINGS.   As of the  date of this prospectus,  Moody's rating of the City's
general obligation bonds stood at Baa1 and S&P's rating stood at A-. On February
11, 1991, Moody's had lowered its rating from A.
 
    On December 6, 1993, in confirming its Baa1 rating, Moody's noted that:
 
        The fiscal 1994 budget is  nominally balanced, in part through  reliance
    on  one-shot revenues, but contains a number  of risks . . . (T)he financial
    plan . . . shows increased gaps in succeeding years.
 
        The financial plan for fiscal 1995 and beyond shows an ongoing imbalance
    between the City's expenditures and  revenues . . . A  key risk is that  the
    replacement  of one-shot revenues is likely to become increasingly difficult
    over time.  Moody's continues  to  expect that  the City's  progress  toward
    achieving  long-term balance will be slow and uneven, but that the City will
    be diligent and prudent in closing gaps as they arise.
 
    As discussed above under FISCAL YEAR  1993 AND 1993-1996 FINANCIAL PLAN,  on
July  2, 1993  after a  review of the  City's budget  for fiscal  year 1994, its
proposed budget  for  fiscal year  1995  and  certain additional  cuts  in  both
proposed by the Mayor and the City Comptroller, S&P confirmed its A- rating with
a  negative  outlook of  the  City's general  obligation  bonds but  indicated a
continuing concern  about budgets  for fiscal  year 1995  and thereafter.  S&P's
rating of the City's general obligation bonds remains unchanged.
 
    On  October 12, 1993, Moody's increased its rating of the City's issuance of
$650 million of Tax  Anticipation Notes ("TANs") to  MIG-1 from MIG-2. Prior  to
that  date, on May 9,  1990, Moody's revised downward  its rating on outstanding
City revenue anticipation notes from MIG-1  to MIG-2 and rated the $900  million
Notes  then  being sold  MIG-2.  S&P's rating  of  the October  1993  TANS issue
increased to SP-1 from SP-2. Prior to that date, on April 29, 1991, S&P  revised
downward its rating on City revenue anticipation notes from SP-1 to SP-2.
 
    As  of June 30, 1993, the City  and MAC had, respectively, $19.6 billion and
$4.5 billion of outstanding net long-term indebtedness.
 
    (3) THE STATE AGENCIES: Certain Agencies of the State have faced substantial
financial difficulties which could adversely affect the ability of such Agencies
to make payments  of interest  on, and  principal amounts  of, their  respective
bonds.  The  difficulties  have in  certain  instances caused  the  State (under
so-called  "moral  obligation"  provisions   which  are  non-binding   statutory
provisions  for State  appropriations to  maintain various  debt service reserve
funds) to appropriate funds on behalf of the Agencies. Moreover, it is  expected
that  the  problems  faced by  these  Agencies  will continue  and  will require
increasing amounts of State assistance in future years. Failure of the State  to
appropriate  necessary amounts or to take  other action to permit those Agencies
having financial  difficulties  to meet  their  obligations could  result  in  a
default by one or more of the Agencies. Such default, if it were to occur, would
be  likely to have a  significant adverse effect on  investor confidence in, and
therefore the  market  price of,  obligations  of the  defaulting  Agencies.  In
addition,  any default in payment on any  general obligation of any Agency whose
bonds contain a moral obligation provision could constitute a failure of certain
conditions that must be satisfied in connection with Federal guarantees of  City
and  MAC obligations  and could thus  jeopardize the  City's long-term financing
plans.
 
                                       48
<PAGE>
    As of  September 30,  1993,  the State  reported  that there  were  eighteen
Agencies  that each had outstanding debt of $100 million or more. These eighteen
Agencies had  an  aggregate of  $63.5  billion of  outstanding  debt,  including
refunding  bonds, of which $7.7  billion was moral obligation  debt of the State
and $19.3 billion  was financed under  lease-purchase or contractual  obligation
financing arrangements.
 
    (4) STATE LITIGATION: The State is a defendant 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 a number of cases challenging
the constitutionality  or  the  adequacy  and  effectiveness  of  a  variety  of
significant  social  welfare  programs primarily  involving  the  State's mental
hygiene programs. Adverse judgments in  these matters generally could result  in
injunctive  relief coupled with prospective changes  in patient care which could
require substantial increased financing of the litigated programs in the future.
 
    The State  is  also engaged  in  a  variety of  claims  wherein  significant
monetary  damages are sought. Actions commenced  by several Indian nations claim
that significant amounts of land were unconstitutionally taken from the  Indians
in  violation  of  various treaties  and  agreements during  the  eighteenth and
nineteenth centuries. The claimants seek  recovery of approximately six  million
acres of land as well as compensatory and punitive damages.
 
    The  U.S. Supreme Court on March 30,  1993, referred to a Special Master for
determination of damages an action by  the State of Delaware to recover  certain
unclaimed  dividends,  interest  and  other  distributions  made  by  issuers of
securities held by New  York based-brokers incorporated  in Delaware. (STATE  OF
DELAWARE  V. STATE  OF NEW  YORK.) The State  had taken  such unclaimed property
under its ABANDONED  PROPERTY LAW.  New York and  Delaware have  entered into  a
settlement  agreement which provides for a payment of $35 million in fiscal year
1993-94 and thereafter five $33 million annual payments. Claims of other  states
and  the District of Columbia  have not been settled  and the State expects that
additional payments,  which may  be significant,  may be  required with  respect
thereto during fiscal year 1994 and thereafter.
 
    In  SCHULZ V.  STATE OF  NEW YORK, commenced  May 24,  1993 ("SCHULZ 1993"),
petitioners have challenged the constitutionality of mass transportation bonding
programs  of  the  New  York  State  Thruway  Authority  and  the   Metropolitan
Transportation  Authority. On  May 24, 1993,  the Supreme  Court, Albany County,
temporarily enjoined  the State  from implementing  those bonding  programs.  In
previous  actions  Mr.  Schulz and  others  have challenged  on  similar grounds
bonding programs for the  New York State Urban  Development Corporation and  the
New  York  Local Government  Assistance Corporation.  While  there have  been no
decisions on the merits in  such previous actions, by  an opinion dated May  11,
1993,  the New York Court of Appeals held in a proceeding commenced on April 29,
1991 in the Supreme  Court, Albany County  (SCHULZ V. STATE  OF NEW YORK),  that
petitioners  had standing as  voters under the State  Constitution to bring such
action.
 
    Petitioners in SCHULZ 1993 have asserted  that issuance of bonds by the  two
Authorities  is subject to  approval by statewide  referendum. By decision dated
October 21, 1993, the Appellate  Division, Third Department, affirmed the  order
of  the Supreme  Court, Albany County,  granting the State's  motion for summary
judgment, dismissing the complaint and vacating the temporary restraining order.
In December 1993, the New York Court of Appeals indicated that it would hear the
plaintiffs' appeal of the Appellate Division's decision in SCHULZ 1993. At  this
time  there can be no forecast of the likelihood of success on the merits by the
petitioners, but  a  decision  upholding  this  constitutional  challenge  could
restrict  and limit the ability of the State and its instrumentalities to borrow
funds in the future.
 
                                       49
<PAGE>
    Adverse developments in the foregoing  proceedings or new proceedings  could
adversely affect the financial condition of the State in the future.
 
    (5)  OTHER MUNICIPALITIES: Certain  localities in addition  to New York City
could  have  financial  problems  leading  to  requests  for  additional   State
assistance.  The potential impact on the State  of such actions by localities is
not included in projections  of State receipts and  expenditures in the  State's
1993-94 and 1994-95 fiscal years.
 
    Fiscal  difficulties experienced by the City of Yonkers ("Yonkers") resulted
in the creation  of the Financial  Control Board  for the City  of Yonkers  (the
"Yonkers  Board")  by the  State  in 1984.  The  Yonkers Board  is  charged with
oversight of the fiscal affairs of Yonkers. Future actions taken by the Governor
or the State Legislature to assist  Yonkers could result in allocation of  State
resources in amounts that cannot yet be determined.
 
    Municipalities  and school districts have  engaged in substantial short-term
and long-term borrowings. In 1991, the  total indebtedness of all localities  in
the  State was approximately $31.6  billion, of which $16.8  billion was debt of
New York  City (excluding  $6.7 billion  in MAC  debt). State  law requires  the
Comptroller  to review and make recommendations  concerning the budgets of those
local government units other than New York City authorized by State law to issue
debt to  finance deficits  during  the period  that  such deficit  financing  is
outstanding. Fifteen localities had outstanding indebtedness for state financing
at  the close of their  fiscal year ending in 1991.  In 1992, an unusually large
number of local government units requested authorization for deficit financings.
According to the Comptroller, ten local government units have been authorized to
issue deficit financing in the aggregate amount of $131.1 million.
 
    Certain proposed Federal  expenditure reductions  could reduce,  or in  some
cases  eliminate, Federal funding  of some local  programs and accordingly might
impose substantial increased expenditure requirements on affected localities. If
the State, New York City or any of the Agencies were to suffer serious financial
difficulties jeopardizing their respective access to the public credit  markets,
the  marketability of  notes and  bonds issued  by localities  within the State,
including notes  or bonds  in the  New York  Insured Trust,  could be  adversely
affected. Localities also face anticipated and potential problems resulting from
certain  pending litigation, judicial decisions, and long-range economic trends.
The longer-range potential  problems of declining  urban population,  increasing
expenditures,  and other economic  trends could adversely  affect localities and
require increasing State assistance in the future.
 
    (6) OTHER ISSUERS OF NEW YORK  MUNICIPAL OBLIGATIONS. There are a number  of
other  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
obligations backed by the full faith and credit of the State.

NEW YORK 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,  state and  local taxes, using  published 1994  marginal
Federal tax rates and marginal state and local 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  two state  or local  brackets fall  within a federal
bracket, the higher state or local bracket is combined with the federal bracket.
The combined local, state and Federal  tax brackets shown reflect the fact  that
state  and local 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  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 the New York State supplemental income
tax based upon a taxpayer's New York State taxable income and New York State adjusted gross income. This supplemental tax results
in  an increased marginal state income  tax rate to the extent  a taxpayer's New York State  adjusted gross income ranges between
$100,000 and $150,000. The  table does not, however,  reflect the amendments to  the New York State  income tax law that  imposes
limitations  on the deductibility of itemized deductions. The application of the New York State limitation on itemized deductions
may result in a higher combined Federal, State and local tax rate than indicated in the table. The table assumes for this purpose
that a taxpayer's New York State adjusted income equals his Federal adjusted gross income.
      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  July 5,  1994.  Contracts
  relating  to  Bonds  with delivery  dates  after  the date  of  settlement for
  purchase made  on the  Date of  Deposit constitute  approximately 13%  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 734:
    
 
   
       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  734
     (comprising  Connecticut Traditional  Trust 265,  Virginia Traditional
     Trust 288, Arizona Insured Trust 33, Florida Insured Trust 192 and New
     York Insured  Trust  218),  as  of  June  14,  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  734
     as  of June 14, 1994, in conformity with generally accepted accounting
     principles.

(1) Represented by contracts  to purchase Tax-Exempt  Bonds which include "when  issued" or "regular  way" or "delayed  delivery"
    contracts  for which an irrevocable letter of  credit issued by a major commercial  bank has been deposited with the Trustee.
    The amount of such letter of credit  and any cash deposited exceeds the amount  necessary for the purchase of the Bonds  plus
    accrued  interest to the Date of  Deposit. 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 rights, title and  interest in and to  such
    Bonds.
(2)  Aggregate value (at offering prices) as of the Date of  Deposit of the Bonds listed under "Schedules of Investments" herein,
    and their aggregate cost to the Trusts are the same. Such offering prices were determined by Kenny S&P Evaluation Services as
    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
    Units. Both the bid and the offering prices of the underlying  Bonds and of the Units may include value attributable to  such
    policies of insurance.
(3) Representing, as set forth in Section 8, advancement by the Trustee of an amount equal to the accrued Bond interest as of the
    Date of Deposit from the later of the last payment date on the Bonds or the date of issuance thereof.
(4) Aggregate Public Offering Price (exclusive of accrued interest) computed as set forth under Section 6.
(5) The gross underwriting commission has been calculated on the assumption that the Units offered by this prospectus are sold in
    single transactions involving less than $50,000 or 500 Units. At this level, the sales charge is 4.90% of the Public Offering
    Price  in the case of National and State Trusts, 4.25% thereof in  the case of Long Intermediate Trusts, 3.90% in the case of
    Intermediate Trusts, 3.00% in the  case of Short Intermediate Trusts  and 2.50% in the case  of Short Term Trusts. In  single
    transactions involving 500 Units or more, the sales charge is reduced. (See Section 6.)

(1)  Represented by contracts  to purchase Tax-Exempt  Bonds which include "when  issued" or "regular  way" or "delayed delivery"
    contracts for which an irrevocable letter of  credit issued by a major commercial  bank has been deposited with the  Trustee.
    The  amount of such letter of credit and  any cash deposited exceeds the amount necessary  for the purchase of the Bonds plus
    accrued interest to the Date of  Deposit. 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 rights, title and  interest in and to such
    Bonds.

    Price in the case of National and State Trusts, 4.25% thereof  in the case of Long Intermediate Trusts, 3.90% in the case  of
    Intermediate  Trusts, 3.00% in the case  of Short Intermediate Trusts and  2.50% in the case of  Short Term Trusts. In single
    transactions involving 500 Units or more, the sales charge is reduced. (See Section 6.)

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 of such acquisition to all Unitholders of the
Trust involved. 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, 1993  the Insurer had  admitted assets  of $3.1  billion
(audited),  total liabilities of  $2.1 billion (audited),  and total capital and
surplus of  $978  million  (audited) determined  in  accordance  with  statutory
accounting   practices   prescribed   or  permitted   by   insurance  regulatory
authorities. As  of March  31, 1994,  the Insurer  had admitted  assets of  $3.2
billion  (unaudited), total liabilities  of $2.2 billion  (unaudited), and total
capital and surplus of  $998 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.
 
    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  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 the aggregate offering prices in the
case of National and  State Trusts, 4.439% of  the aggregate offering prices  in
the case of Long Intermediate Trusts, 4.058% of the aggregate offering prices in
the  case of Intermediate Trusts, 3.093% of the aggregate offering prices in the
case of Short Intermediate Trusts and 2.564% of the aggregate offering prices 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 $50,000 or  500 Units and will be
applied on whichever basis is more  favorable to the purchaser. For purposes  of
calculating  the applicable  sales charge,  purchasers who  have indicated their
intent to purchase a specified amount of Units of any Trust described herein  in
the  primary offering period or  units of any other  series of Nuveen Tax-Exempt
Unit Trusts in the primary offering period by executing and delivering a  letter
of intent to the Sponsor, which letter of intent must be in a form acceptable to
the
 
                                      A-12
<PAGE>
Sponsor  and shall have a maximum duration  of thirteen months, will be eligible
to receive a reduced sales charge according to the following table based on  the
amount  of intended aggregate purchases as expressed in the letter of intent. By
establishing a letter of intent, a Unitholder agrees that the first purchase  of
Units  following the execution of  such letter of intent will  be at least 5% of
the  total  amount  of  the  intended  aggregate  purchases  expressed  in  such
Unitholder's  letter of intent. Further, through the establishment of the letter
of intent, such Unitholder agrees that units representing 5% of the total amount
of the intended purchases will be held in escrow by United States Trust  Company
of  New York pending  completion of these purchases.  All distributions on units
held in escrow will be credited to such Unitholder's account. If total purchases
prior to the  expiration of  the letter  of intent  period equal  or exceed  the
amount  specified in a Unitholder's  letter of intent, the  units held in escrow
will be transferred  to such Unitholder's  account. If the  total purchases  are
less  than the amount specified, the Unitholder involved must pay the Sponsor an
amount equal to the difference between the amounts paid for these purchases  and
the  amounts which  would have  been paid  if the  higher sales  charge had been
applied. If such Unitholder  does not pay the  additional amount within 20  days
after   written  request   by  the   Sponsor  or   the  Unitholder's  securities
representative, the Sponsor will instruct  the Trustee to redeem an  appropriate
number  of the escrowed  units to meet  the required payment.  By establishing a
letter of intent, a Unitholder irrevocably  appoints the Sponsor as attorney  to
give instructions to redeem any or all of such Unitholder's escrowed units, with
full  power  of substitution  in the  premises. A  Unitholder or  his securities
representative must notify the Sponsor whenever such Unitholder makes a purchase
of Units that he wishes to be counted towards the intended amount. Sales charges
during the primary offering period are as follows:

*Breakpoint sales charges are computed both on  a dollar basis and on the  basis
 of the number of Units purchased, using the equivalent of 500 Units to $50,000,
 2,500  Units to $250,000 etc., and will be  applied on that basis which is more
 favorable to the purchaser.
 
    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
 
                                      A-13
<PAGE>
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 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  Bonds in  each maturity  range (and
therefore the aggregate sales charge on the purchase) is reduced with respect to
purchases of at least $50,000 or 500 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  500  Units to
  $50,000, 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.
 
                                      A-14
<PAGE>
    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.
 
    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
 
                                      A-15
<PAGE>
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  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
 
                                      A-16
<PAGE>
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. However, due to advances by the Trustee, the Trustee
will provide a first distribution between approximately 30 and 60 days after the
Date  of Deposit. Assuming each Trust  retains its original size and composition
and expenses and fees remain the same, 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 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 effect of a first distribution which
may be less than a  regular distribution or may be  paid at some point after  30
days  (or a second distribution which may be less than a normal distribution for
Unitholders who choose quarterly or  semi-annual plans of distribution), and  it
also  does  not  take into  account  the  difference in  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
 
                                      A-17
<PAGE>
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 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.
 
                                      A-18
<PAGE>
    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 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.

<PAGE>
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 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
 
                                      A-20
<PAGE>
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 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.)
 
    The  Trustee receives for ordinary recurring services an annual fee for each
plan of  distribution for  each Trust  as set  forth in  "Essential  Information
Regarding  the Trusts." Each  annual fee is  per $1,000 principal  amount of the
underlying Bonds in a Trust for that
 
                                      A-21
<PAGE>
portion of the  Trust that  represents a  particular plan  of distribution.  The
Trustee's  fee  may  be periodically  adjusted  in response  to  fluctuations in
short-term interest rates (reflecting the cost to the Trustee of advancing funds
to a  Trust to  meet scheduled  distributions) and  may be  further adjusted  in
accordance  with  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  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
 
                                      A-22
<PAGE>
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 fees
and expenses remain the same, and will generally change when Bonds are redeemed,
mature or are sold or when fees and expenses increase or decrease.
 
    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. The Trustee's  fee
takes  into account the  costs attributable to  the outlay of  capital needed to
make such advances.
 
                                      A-23
<PAGE>
    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.

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 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
 
                                      A-24
<PAGE>
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 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
 
                                      A-25
<PAGE>
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.
 
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
 
                                      A-26
<PAGE>
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 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.
 
                                      A-27
<PAGE>
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, 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:

*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 500 Units to  $50,000, 2,500 Units to  $250,000 etc. and will  be
 applied on that basis which is more favorable to the purchaser.

<PAGE>
    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 500 Units to $50,000, 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 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 by book  entry positions  recorded on  the
books  and records of the Trustee  unless the Unitholder expressly requests that
the purchased Units be evidenced in Certificate form. 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
 
                                      A-29
<PAGE>
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 guarantor 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.
 
    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% 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 0.5% 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
 
                                      A-30
<PAGE>
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 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
 
                                      A-31
<PAGE>
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.
 
    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
 
                                      A-32
<PAGE>
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.
 
22.  INFORMATION ABOUT THE TRUSTEE
 
The Trustee is United States Trust Company of New York, with its principal place
of  business at 114 West 47th Street, New York, New York 10036 and its corporate
trust office at  770 Broadway,  New York, New  York 10003.  United States  Trust
Company  of New York, established in  1853, has, since its organization, engaged
primarily in the  management of trust  and agency accounts  for individuals  and
corporations. The Trustee is a member of the New York Clearing House Association
and  is subject to supervision and examination by the Superintendent of Banks of
the State of New York, the  Federal Deposit Insurance Corporation and the  Board
of  Governors of the Federal Reserve System.  In connection with the storage and
handling of  certain Bonds  deposited in  the Trusts,  the Trustee  may use  the
services   of  The  Depository  Trust  Company.  These  services  would  include
safekeeping of the Bonds and  coupon-clipping, computer book-entry transfer  and
institutional  delivery  services. The  Depository  Trust Company  is  a limited
purpose trust company organized under the Banking Law of the State of New  York,
a  member of the Federal  Reserve System and a  clearing agency registered under
the Securities Exchange Act of 1934.
 
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.
 
                                      A-33
<PAGE>
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.

companies  currently have  approximately $32.8 billion  in tax-exempt securities
under management.  Nationwide, more  than  1,000,000 individual  investors  have
purchased  Nuveen's tax  exempt trusts  and funds.  The present  corporation was
organized in 1967 as a wholly-owned subsidiary of Nuveen Corporation,  successor
to  the original John Nuveen & Co. founded  in 1898 as a sole proprietorship and
incorporated in  1953.  In  1974,  John  Nuveen  &  Co.  Incorporated  became  a
wholly-owned  subsidiary of The  St. Paul Companies,  Inc., a financial services
management company  located in  St. Paul,  Minnesota. On  May 19,  1992,  common
shares  comprising a  minority interest  in The  John Nuveen  Company ("JNC"), a
newly organized corporation which holds all  of the shares of Nuveen, were  sold
to  the  general  public in  an  initial  public offering.  St.  Paul  retains a
controlling interest in  JNC with over  70% of  JNC's shares. The  Sponsor is  a
member  of  the  National  Association  of  Securities  Dealers,  Inc.  and  the
Securities Industry Association and has its principal offices located in Chicago
(333 W. Wacker Drive) and New York  (Swiss Bank Tower, 10 East 50th Street).  It
maintains 14 regional offices.
 
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
 
                                      A-35
<PAGE>
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
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

    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
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 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
 
                                      A-38
<PAGE>
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
333 W. Wacker Drive
Chicago, Illinois  60606

RE:  Nuveen Tax-Exempt Unit Trust, Series 734

Gentlemen:

    We have served as counsel for you, as Depositor of Nuveen Tax-Exempt Unit
Trust, Series 734 (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 book entry position or certificate, if requested by the purchaser of 
Units, 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 734.

    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. 33-53707) 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.

John Nuveen & Co. Incorporated
333 West Wacker Drive
Chicago, Illinois  60606
RE:  Nuveen Tax-Exempt Unit Trust, Series 734
     Connecticut Traditional Trust 265

Gentlemen:

        You have requested that we act as special counsel with respect to
certain Connecticut tax aspects of Connecticut Traditional Trust 265 (the
"Connecticut Traditional Trust"), being created as part of the Nuveen
Tax-Exempt Unit Trust, Series 734 (the "Fund").
       
        The Fund is created under a 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.  The Fund will issue units in 
several state trusts, one of which is the Connecticut Traditional Trust.
Each unit of the Connecticut Traditional Trust (a "Unit") represents a 
fractional undivided interest in the principal and net income of the 
Connecticut Traditional Trust.  The Connecticut Traditional Trust and the 
trust for any other state included in the Fund will each be administered 
as a separate and distinct entity for all purposes, each having its own 
separate assets, accounts, and certificates.

        You have informed us that, upon the sale of Units of the Connecticut
Traditional Trust to investors (the "Unitholders"), the assets of the
Connecticut Traditional Trust will consist of certain obligations 
(the "Bonds").  Each of the Bonds has been issued by or on behalf of the 
State of Connecticut, a political subdivision thereof, or public 
instrumentality, state or local authority, district, or similar public 
entity created under the laws of the State of Connecticut or by or on 
behalf of a United States territory or possession the interest on the   

<PAGE>

obligations of which Federal law would prohibit Connecticut from taxing 
if received directly by a Unitholder.  In the opinion of bond counsel to the
issuer of each of the Bonds, the interest thereon is exempt from Federal 
income taxation. Distributions to Unitholders of interest received by the 
Connecticut Traditional Trust and of amounts received thereby upon the
maturity, redemption, sale, or other disposition of the Bonds will be made 
semi-annually except in the case of Unitholders who have elected a shorter 
distribution period.

        You have informed us that, in the opinion of Messrs. Chapman and 
Cutler, for Federal income tax purposes (i) the Connecticut Traditional Trust
will not be classified as an association, but will be governed by the
provisions of subchapter J of chapter 1 of the Internal Revenue Code of 1986,
relating to trusts;  (ii) pursuant to subpart E of said subchapter J, each
Unitholder will be considered to be the owner of a portion of each asset of
the Connecticut Traditional Trust and to have a portion of each item of
income of the Connecticut Traditional Trust, in each case such portion being
equal to the part of the whole thereof that the number of Units of the
Connecticut Traditional Trust held by him bears to the total number of
outstanding Units of the Connecticut Traditional Trust; (iii) each such
item of income will have the same character in the hands of a Unitholder as
in the hands of the Trustee; (iv) gain or loss will be recognized by a
Unitholder upon the redemption or sale of his Units or upon the maturity,
redemption, sale, or other disposition of a Bond held by the Connecticut
Traditional Trust; and (v) such income will be excludable from a Unitholder's
Federal gross income to the extent it consists of interest excludable
therefrom for Federal income tax purposes.
 
        Based on the foregoing, and relying explicitly on the opinion of 
Messrs. Chapman and Cutler regarding Federal income tax matters, we are of 
the opinion that, under existing Connecticut law:

1.   The Connecticut Traditional Trust is not liable for any tax on
     or measured by net income imposed by the State of Connecticut.

<PAGE>

2.   Interest income from a Bond held by the Connecticut Traditional
     Trust is not taxable under the Connecticut tax on the Connecticut
     taxable income of individuals, trusts, and estates (the "Connecticut 
     Income Tax"), when such interest is received by the Connecticut 
     Traditional Trust or distributed by it to a Unitholder.

3.   Gains and losses recognized by a Unitholder for Federal income tax 
     purposes upon the maturity, redemption, sale, or other disposition by the 
     Connecticut Traditional Trust of a Bond held by the Connecticut 
     Traditional Trust or upon the redemption, sale, or other disposition of a 
     Unit of the Connecticut Traditional Trust held by a Unitholder are taken 
     into account as gains or losses, respectively, for purposes of the 
     Connecticut Income Tax, except that, in the case of a Unitholder holding
     a Unit of the Connecticut Traditional Trust as a capital asset, such gains
     and losses recognized upon the sale or exchange of a Bond issued by or on
     behalf of the State of Connecticut, any political subdivision thereof, or
     public instrumentality, state or local authority, district, or similar
     public entity created under the laws of the State of Connecticut
     (a "Connecticut Bond") held by the Connecticut Traditional Trust are
     excluded from gains and losses taken into account for purposes of such
     tax and no opinion is expressed as to the treatment for purposes of such
     tax of gains and losses recognized upon the maturity or redemption of a
     Connecticut Bond held by the Connecticut Traditional Trust or, to the 
     extent attributable to Connecticut Bonds, of gains and losses recognized 
     upon the redemption, sale, or other disposition by a Unitholder of a Unit
     of the Connecticut Traditional Trust held by him.

4.   The portion of any interest income or capital gain of the Connecticut
     Traditional Trust that is allocable to a Unitholder that is subject to 
     the Connecticut corporation business tax is includable in the gross 
     income of such Unitholder for purposes of such tax.

<PAGE>

5.   An interest in a Unit of the Connecticut Traditional Trust that is owned
     by or attributable to a Connecticut resident at the time of his death is 
     includable in his gross estate for purposes of the Connecticut succession
     tax and the Connecticut estate tax.

          

        We hereby consent, without admitting that we are in the category of
persons whose consent is required, to the filing of this opinion as an exhibit
to the Registration Statement relating to the Units and to the reference to 
our firm as special Connecticut tax counsel in such Registration Statement 
and the Prospectus contained therein.

        We understand that you may deliver a copy of this opinion to the 
Trustee and hereby consent to the Trustee's relying on this opinion as though 
it were addressed to the Trustee.

Very truly yours,

Attn:  James J. Wesolowski, Esquire
       General Counsel


United States Trust Company of New York,
as Trustee of Nuveen Tax-Exempt Unit Trust
Series 734
288
770 Broadway
New York, New York  10003

Gentlemen:

    We have acted as special Virginia counsel to Nuveen Tax-Exempt Unit Trust,
Series 734 (the "Fund") concerning a Registration Statement (No. 33-53707)
under the Securities Act of 1933, as amended (the "Registration Statement"),
covering the issuance by the Fund of units of fractional undivided
interest pursuant to a Trust Indenture and Agreement dated as of the date
hereof between John Nuveen & Co. Incorporated and United States Trust Company
of New York.  The Fund will issue units in several State Trusts, one of which
is the Virginia Traditional Trust (the "Virginia Trust" or "Trust", the
units of which are referred to as "the Units").  The Units will be purchased
by various investors (the "Unitholders").  Each Trust will be administered as
a distinct entity with separate certificates, investments, expenses, books
and records.
    The assets of the Virginia Trust will consist of interest-bearing
obligations issued by or on behalf of the Commonwealth of Virginia, its
counties, municipalities, authorities or political subdivisions, and, provided
the interest thereon is exempt from Virginia income taxes by the laws or
treaties of the United States, by or on behalf of United States territories
or possessions, including Puerto Rico, Guam, the Virgin Islands and the
Northern Mariana Islands, and their political subdivisions and authorities
(the "Bonds").

    You have requested our opinion as to the application of Virginia state and
local taxes to the Trust and the Unitholders.  In rendering our
opinion, we have assumed that the interest on all Bonds in the Trust will be 
exempt from Federal income tax.  Furthermore, in rendering our opinion, we 
have relied on the opinion of Messrs. Chapman and Cutler, of even date 
herewith, that:
 
    (1)  the Trusts are not associations taxable as corporations for Federal
income tax purposes and 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 distributed to a Unitholder;

    (2)  each Unitholder of a Trust is considered to be the owner of a
pro rata portion of such Trust under Subpart E, sub-chapter J of Chapter 1 of
the Internal Revenue Code of 1986 and will have a taxable event when the Trust
disposes of a Bond or when the Unitholder redeems or sells Units . . . .
If the Trustee disposes of Bonds (whether by sale, payment on 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.
 
    Based upon the foregoing, we are of the following opinion:

    The Trust will be treated as a trust for Virginia income tax purposes and
not as an association taxable as a corporation.  As a result, income of the
Trust will be treated as the income of the Unitholders.

<PAGE>

    The calculation of Virginia taxable income begins with federal adjusted
gross income in the case of an individual or federal taxable income in the 
case of a corporation, estate or trust.  Certain modifications are specified, 
but no such modification would require the addition of interest on the Bonds.
Accordingly, amounts representing tax-exempt interest for federal income tax
purposes received or accrued by the Trust with respect to the Bonds, will not 
be taxed to the Trust or to the Unitholders for Virginia income tax
purposes.  To the extent that interest on obligations of the Commonwealth or
any political subdivision or instrumentality thereof is included in federal
adjusted gross income, Virginia law provides that the income shall be 
subtracted in arriving at Virginia taxable income.  In addition, Virginia 
income tax exemption is independently provided for interest on certain 
obligations, including those issued by industrial development authorities 
created pursuant to the Virginia Industrial Development and Revenue Bond Act, 
by the Virginia Housing Development Authority, by the Virginia Resources 
Authority and by the Virginia Education Loan Authority.  Where such an 
independent exemption is provided, interest on such obligations is exempt 
from Virginia income taxation without regard to any exemption from federal 
income taxes.


    As a general rule, to the extent that gain (whether as a result of the
sale of Bonds by the Trust or as a result of the sale of a Unit by the
Unitholder) is subject to federal income taxation, such gain will be
included in the Unitholder's Virginia taxable income.  Under the
language of certain enabling legislation, however, such as the Virginia 
Industrial Development and Revenue Bond Act, the Virginia Resources Authority
Act and the Virginia Housing Development Authority Act, profit made on the
sale of obligations issued by authorities created thereunder is expressly
exempt from Virginia income taxation.  Such enabling legislation does not
appear to require a disallowance in the calculation of Virginia taxes of any
loss that may be deductible for federal income tax purposes with respect to
such obligations, although the Virginia Department of Taxation has taken a
contrary view.

    No income tax is imposed by any political subdivision of the Commonwealth 
of Virginia.  The Units and the obligations represented thereby are exempt 
from the Virginia tax on intangibles (other than the tax on the capital of
banks, as to which no opinion is expressed).  Intangibles (other than
merchants' capital) are not subject to taxation by any political subdivision.

    The Commonwealth of Virginia does not impose a gift tax.  The Virginia
estate tax is equal to the maximum state death tax credit allowable against 
the federal estate tax payable by the estate.

    We have not examined any of the Bonds, nor have we made any review of the
proceedings relating to the issuance of the Bonds or the basis for any 
opinions with respect to their validity or the tax-exempt status thereof for 
federal income tax purposes.  We have made no independent investigation as 
to, or passed on, the operation of the Trust or the sale of the Units in 
Virginia or in any other state.  No opinion was requested, nor is any opinion 
expressed, with respect to any tax consequences to the sponsor of the Trust, 
any underwriters, or any broker-dealers.

    We should point out that to the extent the Trust consists of property of
persons domiciled in Virginia, the Trust will in our opinion be considered a
"resident trust" for Virginia income tax purposes.  While we do not believe 
that the mere ownership by the Trust of the Bonds constitutes sufficient 
nexus to subject the Trust to the tax jurisdiction of Virginia, we express no 
opinion as to whether any activities with respect to the sale of Units in 
Virginia may establish such a nexus.  If a sufficient nexus exists, then if 
the Trust is required to file a federal fiduciary income tax return it will 
also be required to file a Virginia fiduciary income tax return.  Any such 
return would be for information purposes only, since each transaction of the 
Trust should be treated as a transaction of the several Certificateholders,
and not as a transaction of the Trust that could give rise to Virginia
taxable income of the Trust.
 
    We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the use of our name and the reference to our firm in the
Registration Statement and the prospectus included therein.

Very truly yours,

          Re:   
               Arizona Insured Trust 33
Gentlemen:

         We have acted as counsel to Nuveen Tax-Exempt Unit Trust, Series
734, with respect to certain matters preliminary to the issuance and sale 
of units of interest therein (the "Units") pursuant to a Trust Indenture and
Agreement, dated as of the date hereof (the "Indenture"), between John
Nuveen & Co. Incorporated, as depositor (the "Depositor"), and United States
Trust Company of New York, as trustee (the "Trustee").  The Units represent
fractional undivided interests in the principal of and net income on
obligations deposited in one of several separate trusts, including the
above-captioned trust (the "Trust"), will be evidenced by a certificate
(the "Certificate") and will be sold to various investors (the "Unitholders").
Each separate trust will be administered as a distinct entity with
separate certificates, investments, expenses, books and records.

         The assets of the Trust will consist of interest-bearing obligations
issued by or on behalf of the State of Arizona (the "State"), its political
subdivisions and authorities (the "Arizona Bonds"), and by or on behalf of
the government of Puerto Rico, the goverment of Guam, or the goverment
of the Virgin Islands (collectively the "Posession Bonds")
(collectively the Arizona Bonds and Possession Bonds shall be referred to
herein as the "Bonds"), provided the interest on such Bonds is exempt from
State income taxes.  Distributions of interest on the Bonds received by the
Trust will be made semi-annually unless a Unitholder elects to receive
them monthly or quarterly.

         Although we express no opinion with respect thereto, in rendering
the  opinion expressed herein, we have assumed that the Bonds were validly
issued by the State of Arizona, or its instrumentalities or municipalities
and by or on behalf of territories or possessions of the United States of
America, or its instrumentalities or municipalities, as the case may be.


PAGE END

<PAGE>

         Based on the foregoing, and review and consideration of existing
State laws, it is our opinion, and we herewith advise you, as follows:

         (1)  For State income tax purposes, each Unitholder will be
treated as the owner of a pro rata portion of the Trust, and the income of the
Trust will therefore be treated as the income of the Unitholder under
State law.

         (2)  For State income tax purposes, interest on the Arizona
Bonds and the Possession Bonds which is excludable from Federal gross income
and which is exempt from State income taxes when received by the Trust,
and which would be excluable from Federal gross income and exempt from
State income taxes if recieved directly by a Unitholder, will retain
its status as tax-exempt interest when received by the Trust and
distributed to the Unitholders.

         (3)  To the extent that interest derived from the Trust by a
Unitholder with respect to the the Arizona Bonds and Possession Bonds
is excludable from Federal gross income, such interest will not be
subject to State income taxes.

         (4)  Each Unitholder will realize taxable gain or loss for
State income tax purposes when Bonds held in the Trust are sold, exchanged,
redeemed prior to maturity or paid at maturity, or when the Unitholder
redeems or sells his Unit(s), at a price that differs from original cost as
adjusted for accretion of any discount or amortization of any premium and
other basis adjustments, including any basis reduction that may be required to
reflect a Unitholder's share of interest, if any, accruing on Bonds
during the interval between the Unitholder's settlement date and the
date such Bonds are delivered to the Trust, if later.

         (5)  State law does not permit a deduction for interest paid or
incurred on indebtedness incurred or continued to purchase or carry Units in
the Trust, the interest on which is exempt from State income taxes.

         (6)  Neither the Bonds nor the Units will be subject to State
property taxes, sales taxes or use taxes.

         (7)  In the case of Trusts for which an insurance policy or policies
with respect to the payment of principal and interest on the Arizona Bonds and
Possession Bonds has been obtained by the Depositor, any proceeds paid under
such policy or policies issued to the Trust, if any, with respect to the Bonds
in the Trust which represent maturing interest on defaulted obligations held
by the Trustee will be exempt from State income taxes if, and to the same
extent as, such interest would have been so exempt if paid by the issuer of
the defaulted obligations.

         We have not examined any of the Bonds to be deposited and held in
the Trust or the proceedings for the issuance thereof or the opinions of bond
counsel with respect thereto, and therefore express no opinion as to the
exemption from State income taxes of interest on the Bonds if received
directly by a Unitholder.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (No. 33-53707) filed pursuant to the Securities Act of
1933, as amended (the "Act"), with respect to the registration of the sale of
the Units by Nuveen Tax-Exempt Unit Trust, Series 734, and to the 
references to our firm in such Registration Statement and the preliminary 
prospectus included therein.  In giving such consent, we do not thereby admit 
that we are persons whose consent is required by Section 7 of the Act, or the 
rules and regulations thereunder.

Nuveen Tax-Exempt Unit Trust, Series 734
Florida Insured Trust 192
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 192

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, as amended.  In the Florida Income Tax Code, Chapter 220, 
Florida Statutes, the Florida Legistature has adopted, retroactively to 
January 1, 1994, the Internal Revenue Code of 1986, as amended and in effect 
on January 1, 1994, 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, 1994.

    (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.

    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. 33-53707) 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,

(ON EDWARDS & ANGELL LETTERHEAD)

6/14/94

Nuveen Tax-Exempt Unit Trust,
Series 734
In care of John Nuveen & Co. Incorporated
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 734
770 Broadway
New York, NY  10003

Re:  
    New York Insured Trust 218
     
     

Dear Sirs:

    We have acted as special counsel, with respect to New York State and New
York City tax matters, to the above Trusts(s) ("New York Trust(s)") of Nuveen
Tax-Exempt Unit Trust, Series 734 (the "Fund") concerning a
Registration Statement (No. 33-53707) on Form S-6 under the Securities Act of
1933, as amended (the "Registration Statement"), covering the issuance by the
New York Trusts(s) of units of fractional undivided interest in the New York
Trust(s)( "Units").
    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 New York Trust(s) 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, Insured Series 193, dated May 19, 1989, which we were furnished and did
examine. In the case of a Fund which contains a New York Insured Trust or
New York Intermediate Insured Trust, we also were not furnished the
Insurance Agreement (the "Policy") between the Municipal Bond Investors
Assurance Corporation (the "Insurer"), the Depositor and the Trustee.
However, John Nuveen & Co. Incorporated has authorized us to
assume that the Policy will be implemented at the closing of the Trust and
be in substance and form materially similiar to the Policy applicable to
New York Insured Trust 108, which we were furnished and did examine.

    We have not been furnished with a copy of the Opinion of Chapman & Cutler
on the Federal Tax status of the Fund, its constituent Trusts and their
Unitholders.  However, John Nuveen & Co. Incorporated has authorized us to
assume that such Opinion will be in substance and form materially similar to
that which was issued in connection with Nuveen Tax Exempt Unit Trust, Insured
Series 193 dated May 19, 1989, which we were furnished and did examine.

    Based on the foregoing, we are of the opinion that, for purposes of New
York State and New York City franchise taxes, a New York Trust will be a
trust not an association taxable as a corporation; the proposed activities
of a New York Trust will not constitute doing business within the meaning
of section 208.1 of the New York Tax Law or section R46-3.0 of the N.Y.C.
Administrative Code; a New York Trust will not be subject to New York State
or New York City franchise tax imposed on business corporations; a New York
Trust will not be subject to the unincorporated business income tax imposed
by Article 23 of the N.Y. Tax Law or Chapter 46, Title S of the N.Y.C.
Administrative Code; and the income of a New York Trust will be treated as
income of the Unitholders.

    We are further of the opinion that, under existing laws and
administration of the affairs of the New York Trust(s):

    (A)  Interest on obligations issued by New York State, a political
subdivision thereof, 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") which would be exempt from New York State or New York City
personal income tax if directly received by a Unitholder, will retain its
status as tax-exempt interest when received by a New York Trust and
distributed to such Unitholder;

    (B) Interest (less amortizable premium, if any) derived
from a New York Trust by a Unitholder who is a resident of New York State
(or New York City) in respect of Obligations issued by states other than New
York (or their political subdivisions) will be subject to New York State
(or New York City) personal income tax;

<PAGE>


    (C) A Unitholder who is a resident of New York State (or New York City)
will be subject to New York State (or New York City) personal income tax with
respect to gains realized when Obligations held in the Unitholder's respective
New York Trust are sold, redeemed or paid at maturity or when the Unitholder's
Units are sold or redeemed; such gain will equal the proceeds of sale,
redemption or payment less the tax basis of the Obligation or Unit
(adjusted to reflect (a) the amortization of premium or discount (if any) on
Obligations held by the New York Trust, (b) accrued original issue discount
with respect to each Obligation which, at the time the Obligation was issued,
had original issue discount, and (c) the deposit of Obligations with accrued
interest in the New York Trust after the Unitholder's settlement date);

    (D) Interest or gain from a New York Trust derived by a
Unitholder who is not a resident of New York State (or New York City)
will not be subject to New York State (or New York City) personal income
tax, unless the Units are property employed in a business, trade,
profession or occupation carried on in New York State (or New York City);

    (E)  In the case of a New York Insured Trust or New York Intermediate
Insured Trust, amounts paid under the Policies representing maturing interest
on defaulted Obligations held by the Trustee in the Trust will be excludable
from New York State and New York City income if, and to the same extent as,
such interest would have been excludable if paid by the respective
issuer; and

    (F) Amounts distributable from a New York Trust which are, pursuant to
a Unitholder's election, automatically reinvested in Nuveen Municipal
Bond Fund, Inc. will be treated as if actually distributed to and reinvested 
by such Unitholder.

    Because of the requirement that tax cost basis be adjusted as discussed in
(C) above, under some circumstances a Unitholder may realize taxable
gain when his Units are sold or redeemed for an amount equal to or
less than his original cost.

    Although interest on Obligations issued by New York (or a political
subdivision thereof) would generally be exempt from New York State and
New York City tax, a special limitation may apply with respect to private
activity bonds which are not qualified within the meaning of section 103(b)(1)
of the Internal Revenue Code of 1986, as amended.  The interest on such bonds,
to the extent received by a Unitholder who is a "substantial user" (or person
related to such user) of the facilities financed by such bonds, will not be
exempt from New York State and New York City tax for any period during which
such bonds are beneficially held by such "substantial user" or "related
person".

    As an additional matter, if borrowed funds are used to purchase Units
in a New York Trust, all (or part) of the interest on such indebtedness will
not be deductible for New York State and New York City tax purposes.  The
purchase of Units may be considered to have been made with borrowed funds even
though such funds are not directly traceable to the purchase of Units in any
New York Trust.

    We are further of the opinion that, for purposes of the New York State and
New York City franchise tax on corporations, Unitholders which are
subject to such tax will be required to include in their entire net income any
interest or gains distributed to them in respect of obligations of any state
or political subdivision thereof, including New York.  No opinion is rendered
on the includability in entire net income of interest distributed to such
Unitholders in respect of obligations issued 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.

    The foregoing opinions are based upon present provisions of Federal,
New York State and New York City law, administrative interpretations thereof
and court decisions.

    In connection with this offering, we have not examined any of the
obligations to be deposited in the New York Trust(s), and express no opinion
whether the interest on any such obligations is, in fact, exempt from Federal,
New York State, or New York City income taxation, or that such interest would 
be tax-exempt under Federal, New York State, or New York City law if directly
received by a Unitholder, nor have we made any review of the proceedings
relating to the issuance of any such obligations.

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm in such Registration
Statement and the Prospectus included therein.

Very truly yours,



EDWARDS & ANGELL

Re:     NUVEEN TAX EXEMPT UNIT TRUST, SERIES 734

        This is in response to your requests regarding the above-captioned
fund which consists of separate underlying insured and traditional unit
investment trusts, SEC file # 33-53707.

        INSURED TRUSTS.

        With respect to the insured trusts 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 soley 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 attatched 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' to the units of each insured trust and a 'AAA' rating to
the securities contained in each 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 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 Standard and 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
time after the closing or should they not conform to certification received by
us, we reserve the right to nullify the ratings.


<PAGE>



        TRADITIONAL TRUSTS.

        With respect to the traditional unit investment trusts within the
above-captioned fund, we have reviewed the information presented to us and we
hereby confirm that the ratings indicated in the prospectus as being assigned
by Standard & Poor's Corporation to the securities contained in each
traditional trust of such fund are, according to our records, the ratings
currently assigned by Standard & Poor's Corporation to such securities.  You
understand that Standard & Poor's Corporation has not consented to, and will
not consent to, being named as "expert" under the federal securities laws,
including and without limitation, Section 7 of the Securities Act of 1933,
with respect to the ratings on any securities contained in any of the
traditional trusts.

        Please note that the 'AAA' rating assigned to the units of each
insured trust does not apply to the units of any of the traditional trusts.
