NUVEEN  Tax-Exempt Unit Trusts
             PROSPECTUS
            Series 767
             November 18, 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  767 consists  of  three  underlying
separate  unit investment trusts designated  as North Carolina Traditional Trust
282, National Insured  Trust 283 and  New Jersey Insured  Trust 183. 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. (SEE PAGE A-1.)
 
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  income, expense and distribution data  set forth below have been calculated
for  Unitholders   receiving   MONTHLY   distributions.   Unitholders   choosing
distributions  quarterly or  semi-annually will receive  slightly higher returns
because of the lower Trustee's fees and expenses under such plans. (SEE  SECTION
3 FOR DATA RELATING TO THESE PLANS.)

THE NUVEEN TAX-EXEMPT UNIT TRUST
   
SERIES 767
    
 
   
1.  WHAT IS THE NUVEEN TAX-EXEMPT UNIT TRUST, SERIES 767?
    
 
   
Series 767 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  three
underlying  separate unit investment trusts,  combined under one trust indenture
and agreement, designated North Carolina Traditional Trust 282, National Insured
Trust 283 and New Jersey Insured Trust 183. 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
November  18, 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  $17,000,000 (the "Bonds"),
which initially constitute the underlying securities of the
    
 
                                       5
<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 North  Carolina Traditional  Trust,
$10,000,000  in  the National  Insured Trust  and $3,500,000  in the  New Jersey
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 North Carolina Traditional Trust,  100,000 Units of the National  Insured
Trust and 35,000 Units of the New Jersey 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 National  Insured Trust  are offered  for sale  to Virginia  and  Washington
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
 
                                       6
<PAGE>
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.

NORTH CAROLINA TRADITIONAL TRUST 282
    
   
    The  Portfolio  of  North  Carolina  Traditional  Trust  282  consists  of 8
obligations issued by  entities located in  North Carolina. Eight  Bonds in  the
Trust  are payable as  to principal and  interest from the  income of a specific
project or authority and are not supported by the issuer's power to levy  taxes.
The  sources of  payment for  these Bonds  are divided  as follows:  College and
University Revenue,  1;  Electrical  System Revenue,  1;  Health  Care  Facility
Revenue,  2; Municipal  Lease Revenue, 1;  Water and/or Sewer  Revenue, 3. 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  North
Carolina Traditional Trust is 24.4 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 14.1% 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  35% 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,  all  of  which is  covered  by insurance.
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.
 
    Approximately 22% 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. The source  of payment for certain  of
these  Bonds, accounting for 8% of the Trust (included in the above percentage),
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 November 16,
1994  and November 17, 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
 
                                       8
<PAGE>
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  North Carolina Traditional Trust, less  estimated expenses, is estimated to
accrue at the rate  of $.01533 per  Unit per day under  the semi-annual plan  of
distribution,  $.01528 per Unit per day under the quarterly plan of distribution
and $.01519 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 North Carolina 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--NORTH CAROLINA TRADITIONAL TRUST
 
    For  a  discussion of  the  Federal tax  status  of income  earned  on North
Carolina Traditional 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 North Carolina, its political subdivisions and
authorities and, provided  the interest  thereon is exempt  from North  Carolina
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, the  Virgin
Islands,  Guam and the  Northern Mariana Islands),  their political subdivisions
and authorities (the "North Carolina Bonds").
 
    In the opinion of Moore & Van Allen, special North Carolina counsel for  the
Series, under existing law:
 
        The  North Carolina Traditional Trust is not an association taxable as a
    corporation for North Carolina  income tax purposes.  Interest on the  North
    Carolina  Bonds which is exempt from North Carolina income tax when received
    by the North Carolina Traditional Trust will retain its status as tax-exempt
    interest when distributed to Unitholders.
 
                                       9
<PAGE>
        For North  Carolina 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  determined  by  computing  the
    difference  between  the  proceeds of  such  a  redemption or  sale  and the
    Unitholder's adjusted basis for the Units.
 
        For North  Carolina income  tax purposes,  each Unitholder  will have  a
    taxable  event when the North Carolina  Traditional Trust disposes of one of
    the North Carolina Bonds (whether  by sale, payment at maturity,  retirement
    or  otherwise); provided that when  any of the North  Carolina Bonds held by
    the North Carolina Traditional  Trust have been issued  under an act of  the
    General  Assembly of North Carolina that  provides that all income from such
    North Carolina Bond, including a profit made from the sale thereof, shall be
    free from  all taxation  by the  State of  North Carolina,  any such  profit
    received by the Trust will retain its tax-exempt status in the hands of each
    Unitholder.
 
        Ownership  of the Units  representing a pro rata  ownership of the North
    Carolina Bonds is exempt from the North Carolina tax on intangible  personal
    property  so long as the  corpus of the Trust  is composed entirely of North
    Carolina obligations or is  composed entirely of  obligations of the  United
    States  and its possessions  and North Carolina and  at least eighty percent
    (80%) of the fair market value of such obligations represents North Carolina
    obligations; provided that  for this  exemption to apply,  the Trustee  must
    periodically  provide  to  the  North Carolina  Department  of  Revenue such
    information about  the  North  Carolina Traditional  Trust  as  required  by
    applicable law.
 
        Interest  on indebtedness paid or accrued  by a Unitholder in connection
    with ownership of Units in the North Carolina Traditional Trust will not  be
    deductible by the Unitholder for North Carolina state income tax purposes.
 
        Amortization  of  North Carolina  Bond premiums  is mandatory  for North
    Carolina  state  income  tax  purposes  for  all  North  Carolina   resident
    Unitholders.  Amortization for the taxable  year is accomplished by lowering
    the basis or adjusted  basis of the Units,  with no deduction against  gross
    income for the year.
 
        Trust Units will be subject to North Carolina inheritance and estate tax
    if  owned by a North Carolina resident on the date of his death. Neither the
    North Carolina Bonds  nor the Units  will be subject  to the North  Carolina
    sales tax or use tax.
 
ECONOMIC FACTORS--NORTH CAROLINA
 
    The  economic profile of North Carolina consists primarily of manufacturing,
agriculture,  tourism  and  mining.  The  North  Carolina  Employment   Security
Commission's   preliminary  figures   indicate  that   non-agricultural  payroll
employment accounted for  approximately 3,250,500  jobs in  September 1993,  the
largest  segment of which was the approximately 852,600 in manufacturing. During
the period  1985  to  1990,  per  capita income  in  North  Carolina  grew  from
approximately $11,669 to approximately $16,266, an increase of 39.4%.
 
    Agriculture  is  a basic  element in  the economy  of North  Carolina. Gross
agricultural income in 1992 was $5.2 billion, which placed North Carolina  tenth
in  cash receipts  in commodities.  A strong  agribusiness sector  also supports
farmers with farm inputs (fertilizer, insecticide, pesticide and farm machinery)
and processing  of  commodities  produced  by  farmers  (vegetable  canning  and
cigarette manufacturing).
 
    The  North Carolina Department of Commerce,  Division of Travel and Tourism,
has reported that in 1992 approximately $7.6 billion was spent on tourism in the
State (up 12.3% from 1989), and  that approximately $8.0 billion will have  been
spent  by the end of fiscal year 1993.  The Department also estimated that as of
the third  quarter  of  1993  approximately  255,000  people  were  employed  in
tourism-related jobs.
 
                                       10
<PAGE>
    The  North  Carolina  Employment  Security  Commission  estimated  the North
Carolina unemployment rate in September 1993 to be 3.7% of the labor force  (not
seasonably  adjusted)  and  4.2%  (seasonably  adjusted),  as  compared  with an
unemployment  rate  nationwide  of  6.4%  (not  seasonably  adjusted)  and  6.7%
(seasonably adjusted).
 
    General  obligations of  the State  are currently  rated "AAA"  and "Aaa" by
Standard & Poor's and Moody's, respectively. There can be no assurance that  the
economic conditions in which these ratings, or the ratings of the other bonds in
the Portfolio, are based will continue or that particular bond issues may not be
adversely   affected  by  changes  in   economic  or  political  conditions,  by
uncertainties peculiar to the issuers thereof or the revenue sources from  which
they  are to be  paid. The factual  information provided above  was derived from
publications of various North Carolina departments or agencies and has not  been
independently  verified.  Investors are  encouraged to  consult the  Schedule of
Investments at Date  of Deposit  for the  North Carolina  Traditional Trust  and
their  own investment advisors  regarding the merits of  particular bonds in the
Portfolio.
 
NORTH CAROLINA 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.

NATIONAL INSURED TRUST 283
    
   
    The  Portfolio  of  National Insured  Trust  283  consists of  12  long term
(approximately 15 to 40 year maturities) obligations issued by entities  located
in 11 states. Two Bonds in the Trust are general obligations of the governmental
entities  issuing them and are backed by the taxing powers thereof. Ten 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, 2;  Electrical  System
Revenue,  3; Health Care Facility Revenue, 2; Municipal Lease Revenue, 2. All of
the Bonds  in  the  Trust, as  insured,  are  rated AAA  by  Standard  &  Poor's
Corporation  and Aaa by Moody's Investors Service, Inc. Seventeen percent of the
principal amount of Bonds in the Trust consists of issues of entities located in
the State of California; such concentration  may involve more risk than if  such
Bonds were issued by issuers located in several states.
    
 
   
    At  the Date of Deposit,  the average maturity of  the Bonds in the National
Insured Trust is 28.2  years. The average  maturity of the Bonds  in a Trust  is
calculated based upon the stated maturities of the Bonds in such Trust (or, with
respect  to Bonds for  which funds or  securities have been  placed in escrow to
redeem such Bonds on a stated call date, based upon such call date). The average
maturity of the Bonds in a Trust may  increase or decrease from time to time  as
Bonds mature or are called or sold.
    
 
   
    Approximately  7.5% of  the aggregate principal  amount of the  Bonds in the
Trust (accounting for approximately 7.0% 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 21% 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  on November 17,
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  National Insured Trust, less estimated  expenses, is estimated to accrue at
the rate of $.01832 per Unit per day under the semi-annual plan of distribution,
$.01827 per Unit per day under the

quarterly plan of distribution  and $.01818 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  National 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.
(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--NATIONAL INSURED TRUST
 
    For  a discussion  of the  tax status of  income earned  on National Insured
Trust Units, see Section 11.
 
NATIONALLY DIVERSIFIED TRUST TAXABLE ESTIMATED CURRENT RETURN TABLE
(NATIONAL TRADITIONAL TRUST)
 
    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 tax  payers 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 income
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.

* These Bonds,  or a  portion thereof,  have delivery  dates beyond  the  normal
  settlement date. Their expected delivery dates range from November 30, 1994 to
  December  1, 1994. Contracts  relating to Bonds with  delivery dates after the
  date of  settlement  for purchase  made  on  the Date  of  Deposit  constitute
  approximately 25% of the aggregate principal amount of the Trust. (See Section

NEW JERSEY INSURED TRUST 183
    
   
    The  Portfolio of  New Jersey  Insured Trust  183 consists  of 6 obligations
issued by entities located in New Jersey and one obligation issued by an  entity
located  in the Territory of  Puerto Rico. Three Bonds  in the Trust are general
obligations of the  governmental entities  issuing them  and are  backed by  the
taxing  powers thereof. Four 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; Industrial Revenue, 1; Water and/or Sewer Revenue, 1. All of
the Bonds  in  the  Trust, as  insured,  are  rated AAA  by  Standard  &  Poor's
Corporation and Aaa by Moody's Investors Service, Inc.
    
 
   
    At  the Date of Deposit, the average maturity of the Bonds in the New Jersey
Insured Trust is 29.5  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.
    
 
    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 November  17,
1994.  The following  summarizes certain information  about the Bonds  as of the
business day prior to the Date of Deposit:

</TABLE>
 
    Neither  cost  to  Sponsor  nor   profit  (or  loss)  to  Sponsor   reflects
underwriting  profits or losses received or  incurred by the Sponsor through its
participation  in  underwriting  syndicates.  An  underwriter  or   underwriting
syndicate  purchases bonds  from the issuer  on a negotiated  or competitive bid
basis as principal with  the motive of  marketing such bonds  to investors at  a
profit.  The Sponsor did not participate as  either the sole underwriter or as a
manager or member of a syndicate that  acted as the original underwriter of  any
of the Bonds.
 
   
    Unitholders  may elect  to have  interest distributions  made on  a monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the New Jersey Insured Trust, less estimated expenses, is estimated to accrue at
the rate of $.01683 per Unit per day under the semi-annual plan of distribution,
$.01677 per Unit per  day under the quarterly  plan of distribution and  $.01668
per  Unit per day under the monthly plan of distribution. It is anticipated that
the amount of interest to be distributed  per Unit in each year under each  plan
of  distribution  will initially  be substantially  equal  to the  Estimated Net
Annual Interest Income per Unit for that plan.
    
 
    Details of interest distributions per Unit  of the New Jersey Insured  Trust
under  the various plans appear in the  following table based upon estimated Net
Annual Interest Income at the Date of Deposit:

TAX STATUS--NEW JERSEY INSURED TRUST
 
    For a discussion of the  Federal tax status of  income earned on New  Jersey
Insured Trust Units, see Section 11.
 
    The  assets of the New Jersey Insured Trust will consist of interest-bearing
obligations issued by  or on behalf  of the  State of New  Jersey and  counties,
municipalities,  authorities  and  other  political  subdivisions  thereof,  and
certain territories  of the  United  States, including  Puerto Rico,  Guam,  the
Virgin Islands and the Northern Mariana Islands (the "New Jersey Bonds").
 
    In  the opinion  of Pitney,  Hardin, Kipp  & Szuch,  special counsel  to the
Series for New Jersey tax matters, under existing law:
 
        The New Jersey Insured Trust  will be recognized as  a Trust and not  an
    association  taxable as a corporation. The New Jersey Insured Trust will not
    be subject to  the New  Jersey Corporation Business  Tax or  the New  Jersey
    Corporation Income Tax.
 
        With  respect to the non-corporate Unitholders  who are residents of New
    Jersey, the income of the  New Jersey Insured Trust  will be treated as  the
    income  of such Unitholders under the  New Jersey Gross Income Tax. Interest
    on the underlying New Jersey  Bonds which is exempt  from tax under the  New
    Jersey  Gross Income Tax Law  when received by the  New Jersey Insured Trust
    will retain  its  status as  tax-exempt  interest when  distributed  to  the
    Unitholders.
 
        A  non-corporate Unitholder will not be  subject to the New Jersey Gross
    Income Tax on  any gain realized  either when the  New Jersey Insured  Trust
    disposes  of a  New Jersey Bond  (whether by sale,  exchange, redemption, or
    payment at maturity) or when the Unitholder redeems or sells his Units.  Any
    loss  realized  on such  disposition  may not  be  utilized to  offset gains
    realized by such Unitholder on the  disposition of assets the gain on  which
    is subject to the New Jersey Gross Income Tax.
 
        Units  of the New Jersey Insured Trust may  be taxable on the death of a
    Unitholder under the  New Jersey  Transfer Inheritance  Tax Law  or the  New
    Jersey Estate Tax Law.
 
        If  a Unitholder is a corporation  subject to the New Jersey Corporation
    Business Tax or New Jersey Corporation  Income Tax, interest from the  Bonds
    in the New Jersey
 
                                       20
<PAGE>
    Insured  Trust which is allocable to  such corporation will be includable in
    its entire net income  for purposes of the  New Jersey Corporation  Business
    Tax or New Jersey Corporation Income Tax, less any interest expense incurred
    to  carry such investment to  the extent such interest  expense has not been
    deducted in  computing Federal  taxable income.  Net gains  derived by  such
    corporation  on the disposition  of the New  Jersey Bonds by  the New Jersey
    Insured Trust or on  the disposition of  its Units will  be included in  its
    entire net income for purposes of the New Jersey Corporation Business Tax or
    New Jersey Corporation Income Tax.
 
ECONOMIC FACTORS--NEW JERSEY
 
    As  described above, the New Jersey Insured Trust consists of a portfolio of
New Jersey Bonds. The Trust is  therefore susceptible to political, economic  or
regulatory  factors affecting  issuers of  the New  Jersey Bonds.  The following
information provides  only  a brief  summary  of  some of  the  complex  factors
affecting  the financial  situation in New  Jersey (the "State")  and is derived
from sources that  are generally available  to investors and  is believed to  be
accurate.  It is based  in part on  information obtained from  various State and
local agencies in New Jersey. No  independent verification has been made of  any
of the following information.
 
    New  Jersey is the ninth largest state  in population and the fifth smallest
in land area. With an  average of 1,062 people per  square mile, it is the  most
densely  populated of all the states.  The State's economic base is diversified,
consisting of a variety of  manufacturing, construction and service  industries,
supplemented by rural areas with selective commercial agriculture. Historically,
New Jersey's average per capita income has been well above the national average,
and  in 1993  the State ranked  second among  the states in  per capita personal
income ($26,967).
 
    The New Jersey Economic  Policy Council, a statutory  arm of the New  Jersey
Department  of Commerce  and Economic  Development, has  reported in  NEW JERSEY
ECONOMIC INDICATORS,  a monthly  publication  of the  New Jersey  Department  of
Labor,  Division of Labor Market and Demographic Research, that in 1988 and 1989
employment in  New Jersey's  manufacturing  sector failed  to benefit  from  the
export  boom experienced by many Midwest states and the State's service sectors,
which had  fueled the  State's  prosperity since  1982,  lost momentum.  In  the
meantime,  the prolonged fast growth in the State in the mid 1980s resulted in a
tight labor market situation, which has led to relatively high wages and housing
prices. This  means  that,  while  the  incomes  of  New  Jersey  residents  are
relatively  high,  the State's  business sector  has  become more  vulnerable to
competitive pressures.
 
   
    The onset of  the national recession  (which officially began  in July  1990
according to the National Bureau of Economic Research) caused an acceleration of
New  Jersey's job  losses in  construction and  manufacturing. In  addition, the
national recession  caused an  employment downturn  in such  previously  growing
sectors  as wholesale trade,  retail trade, finance,  utilities and trucking and
warehousing. Reflecting the downturn, the rate of unemployment in the State rose
from a low  of 3.6% during  the first quarter  of 1989 to  an estimated 6.7%  in
October 1994, which is higher than the national average of 5.8% in October 1994.
Economic  recovery  is  likely  to  be  slow  and  uneven  in  New  Jersey, with
unemployment receding at a correspondingly slow pace, due to the fact that  some
sectors may lag due to continued excess capacity. In addition, employers even in
rebounding  sectors can be  expected to remain cautious  about hiring until they
become convinced that improved business  will be sustained. Also, certain  firms
will continue to merge or downsize to increase profitability.

through the sale of the general obligation  bonds of the State. These bonds  are
backed  by the full faith and credit of the State tax revenues and certain other
fees are pledged to  meet the principal and  interest payments and if  provided,
redemption premium payments, if any, required to repay the bonds. As of June 30,
1993,  there was  a total  authorized bond  indebtedness of  approximately $8.98
billion, of which  $3.6 billion  was issued  and outstanding,  $4.0 billion  was
retired  (including bonds for which provision  for payment has been made through
the sale and issuance  of refunding bonds) and  $1.38 billion was unissued.  The
appropriation  for the debt service  obligation on such outstanding indebtedness
is $103.5 million for Fiscal Year 1995.
 
    NEW JERSEY'S BUDGET AND APPROPRIATION SYSTEM. The State operates on a fiscal
year beginning July 1 and ending June 30. At the end of Fiscal Year 1989,  there
was  a  surplus in  the  State's general  fund (the  fund  into which  all State
revenues not  otherwise  restricted by  statute  are deposited  and  from  which
appropriations  are made)  of $411.2  million. At the  end of  Fiscal Year 1990,
there was a surplus in the general fund of $1 million. At the end of Fiscal Year
1991, there was a surplus in the general fund of $1.4 million. New Jersey closed
its Fiscal Year 1992 with a surplus of $760.8 million. It is estimated that  New
Jersey closed its Fiscal Year 1993 with a surplus of $937.4 million.
 
    In  order  to  provide additional  revenues  to balance  future  budgets, to
redistribute school aid and  to contain real property  taxes, on June 27,  1990,
and  July  12,  1990, Governor  Florio  signed  into law  legislation  which was
estimated to raise approximately $2.8 billion in additional taxes (consisting of
$1.5 billion in  sales and  use taxes  and $1.3  billion in  income taxes),  the
biggest  tax hike in New Jersey history. There can be no assurance that receipts
and collections of such taxes will meet such estimates.
 
    The first  part of  the tax  hike  took effect  on July  1, 1990,  with  the
increase in the State's sales and use tax rate from 6% to 7% and the elimination
of  exemptions for certain  products and services not  previously subject to the
tax, such as telephone calls, paper products (which has since been  reinstated),
soaps  and detergents, janitorial services,  alcoholic beverages and cigarettes.
At the  time  of  enactment, it  was  projected  that these  taxes  would  raise
approximately  $1.5 billion in additional  revenue. Projections and estimates of
receipts from sales  and use taxes,  however, have been  subject to variance  in
recent fiscal years.
 
    The  second part of the tax hike took effect on January 1, 1991, in the form
of an increased state income  tax on individuals. At  the time of enactment,  it
was  projected  that this  increase would  raise  approximately $1.3  billion in
additional income taxes to fund a new school aid formula, a new homestead rebate
program and state assumption of  welfare and social services costs.  Projections
and  estimates of receipts from income taxes, however, have also been subject to
variance in  recent  fiscal  years.  Under the  legislation,  income  tax  rates
increased  from their previous range of  2% to 3.5% to a  new range of 2% to 7%,
with the higher rates applying to married couples with incomes exceeding $70,000
who file joint returns, and to individuals filing single returns with incomes of
more than $35,000.
 
    The Florio administration  had contended  that the income  tax package  will
help  reduce  local  property  tax  increases by  providing  more  state  aid to
municipalities.  Under  the  income  tax  legislation  the  State  will   assume
approximately $289 million in social services costs that previously were paid by
counties and municipalities and funded by property taxes. In addition, under the
new formula for funding school aid, an extra $1.1 billion is proposed to be sent
by  the State to school districts beginning  in 1991, thus reducing the need for
property tax increases to support education programs.
 
                                       22
<PAGE>
    Effective July 1, 1992, the State's sales and use tax rate decreased from 7%
to 6%. Effective January 1, 1994, an across-the-board 5% reduction in the income
tax rates was enacted and effective January 1, 1995, further reductions  ranging
from 1% up to 10% in income tax rates will take effect.
 
    On June 30, 1994, Governor Whitman signed the New Jersey Legislature's $15.7
billion  budget for Fiscal  Year 1995. The balanced  budget, which includes $455
million in surplus, is $141 million less than the 1994 budget. Whether the State
can achieve a  balanced budget  depends on its  ability to  enact and  implement
expenditure reductions and to collect estimated tax revenues.
 
    LITIGATION. The State is a party in numerous legal proceedings pertaining to
matters  incidental to the performance  of routine governmental operations. Such
litigation includes, but is  not limited to, claims  asserted against the  State
arising   from  alleged  torts,  alleged  breaches  of  contracts,  condemnation
proceedings and other alleged violations of State and Federal laws. Included  in
the  State's  outstanding litigation  are cases  challenging the  following: the
formula relating to State aid to public  schools, the method by which the  State
shares with its counties maintenance recoveries and costs for residents in State
institutions,  unreasonably low Medicaid payment  rates for long-term facilities
in New  Jersey, the  obligation of  counties to  maintain Medicaid  or  Medicare
eligible  residents  of  institutions  and  facilities  for  the developmentally
disabled, taxes paid  into the Spill  Compensation Fund (a  fund established  to
provide  money for use  by the State  to remediate hazardous  waste sites and to
compensate other persons  for damages incurred  as a result  of hazardous  waste
discharge)   based   on  Federal   preemption,   various  provisions,   and  the
constitutionality, of  the Fair  Automobile Insurance  Reform Act  of 1990,  the
State's  role  in a  consent  order concerning  the  construction of  a resource
facility in Passaic County, actions taken by the New Jersey Bureau of Securities
against  an  individual,   the  State's  actions   regarding  alleged   chromium
contamination  of  State-owned  property  in  Hudson  County,  the  issuance  of
emergency  redirection  orders  and  a   draft  permit  by  the  Department   of
Environmental  Protection and Energy, the adequacy of Medicaid reimbursement for
services rendered by  doctors and  dentists to Medicaid  eligible children,  the
Commissioner  of Health's calculation of the hospital assessment required by the
Health Care Cost  Reduction Act  of 1991,  refusal of  the State  to share  with
Camden  County federal funding the  State recently received for disproportionate
share  hospital  payments  made  to  county  psychiatric  facilities,  and   the
constitutionality  of annual A-901  hazardous and solid  waste licensure renewal
fees collected by the Department of Environmental Protection and Energy. Adverse
judgments in  these and  other matters  could have  the potential  for either  a
significant  loss of revenue  or a significant  unanticipated expenditure by the
State.
 
    At any given  time, there are  various numbers of  claims and cases  pending
against  the State,  State agencies and  employees seeking  recovery of monetary
damages that are  primarily paid out  of the  fund created pursuant  to the  New
Jersey  Tort  Claims Act.  In addition,  at  any given  time, there  are various
numbers of contract claims against the State and State agencies seeking recovery
of monetary damages.  The State  is unable to  estimate its  exposure for  these
claims.
 
    DEBT  RATINGS. For many years prior to 1991, both Moody's Investors Service,
Inc. and Standard and Poor's Corporation had rated New Jersey general obligation
bonds Aaa and "AAA," respectively. On July 3, 1991, however, Standard and Poor's
Corporation downgraded New Jersey general obligation bonds to "AA+." On June  4,
1992, Standard and Poor's Corporation placed New Jersey general obligation bonds
on  CreditWatch with negative  implications, citing as  its principal reason for
its caution the unexpected denial by the
 
                                       23
<PAGE>
   
Federal Government  of New  Jersey's  request for  $450 million  in  retroactive
Medicaid  payments  for  psychiatric  hospitals. These  funds  were  critical to
closing a $1 billion gap in the State's $15 billion budget for fiscal year  1992
which ended on June 30, 1992. Under New Jersey state law, the gap in the current
budget must be closed before the new budget year began on July 1, 1992. Standard
and  Poor's Corporation suggested the State could close fiscal 1992's budget gap
and help fill  fiscal 1993's  hole by  a reversion  of $700  million of  pension
contributions  to its general fund under a  proposal to change the way the State
calculates  its  pension  liability.  On  July  6,  1992,  Standard  and  Poor's
Corporation  reaffirmed its "AA+" rating for New Jersey general obligation bonds
and removed the  debt from  its CreditWatch list,  although it  stated that  New
Jersey's   long-term  financial  outlook  was   negative.  Standard  and  Poor's
Corporation was concerned that the State was entering the 1993 fiscal year  that
began July 1, 1992, with a slim $26 million surplus and remained concerned about
whether  the  sagging  State  economy  would  recover  quickly  enough  to  meet
lawmakers' revenue  projections. It  also remained  concerned about  the  recent
federal  ruling  leaving in  doubt how  much  the State  was due  in retroactive
Medicaid reimbursements and a ruling by a  federal judge, now on appeal, of  the
State's  method for paying for uninsured hospital patients. However, on July 27,
1994, S&P announced that  it was changing the  State's outlook from negative  to
stable  due to a  brightening of the  State's prospects as  a result of Governor
Whitman's effort  to trim  spending and  cut taxes,  coupled with  an  improving
economy. S&P reaffirmed its "AA+" rating at the same time.
    
 
    On  August 24, 1992,  Moody's Investors Service,  Inc. downgraded New Jersey
general obligation  bonds  to "Aa1",  stating  that the  reduction  reflected  a
developing  pattern of  reliance on  nonrecurring measures  to achieve budgetary
balance, four years  of financial  operations marked by  revenue shortfalls  and
operating  deficits, and the  likelihood that serious  financial pressures would
persist. On August 5, 1994, Moody's  reaffirmed its "Aa1" rating, citing on  the
positive  side New Jersey's broad-based economy,  high income levels, history of
maintaining a  positive financial  position and  moderate (albeit  rising)  debt
ratios, and, on the negative side, a continued reliance on one-time revenues and
a dependence on pension-related savings to achieve budgetary balance.
 
NEW JERSEY TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The  following tables show the approximate taxable estimated current returns
for individuals  that are  equivalent to  tax-exempt estimated  current  returns
under  combined Federal and  state taxes, using  published 1994 marginal Federal
tax rates and marginal state tax  rates currently available and scheduled to  be
in  effect.  The  tables  incorporate  increased  tax  rates  for  higher-income
taxpayers that were  included in  the Revenue  Reconciliation Act  of 1993.  For
cases  in which more than one state  bracket falls within a Federal bracket, the
highest state bracket is combined with  the Federal bracket. The combined  state
and  Federal tax  brackets shown  reflect the fact  that state  tax payments are
currently deductible for Federal  tax purposes. The  tables illustrate what  you
would  have to  earn on  taxable investments  to equal  the tax-exempt estimated
current return for your  income tax bracket. A  taxpayer's marginal tax rate  is
affected  by both his taxable income and  his adjusted gross income. Locate your
adjusted gross and  your taxable  income (which  is your  adjusted gross  income
reduced by any deductions and exemptions), then locate your tax bracket based on
joint  or single  tax filing.  Read across  to the  equivalent taxable estimated
current return you would need to match the tax-free income.

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

    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.

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 767:
    
 
   
       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  767
     (comprising  North  Carolina Traditional  Trust 282,  National Insured
     Trust 283 and New Jersey Insured Trust 183), as of November 18,  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  767
     as  of  November  18,  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.)

GENERAL TRUST INFORMATION
 
    RISK FACTORS.
 
    An  investment in Units of any Trust should be made with an understanding of
the risks that such an investment may  entail. These include the ability of  the
issuer,  or,  if  applicable,  an  insurer, to  make  payments  of  interest and
principal when due, the  effects of changes in  interest rates generally,  early
call provisions and the potential for changes in the tax status of the Bonds. 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. For  economic risks  specific  to the  individual Trusts,  see  "Economic
Factors" for each 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
 
                                      A-1
<PAGE>
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  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
 
                                      A-2
<PAGE>
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 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
 
                                      A-3
<PAGE>
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
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
 
                                      A-4
<PAGE>
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 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
 
                                      A-5
<PAGE>
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.
 
    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
 
                                      A-6
<PAGE>
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 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
 
                                      A-7
<PAGE>
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 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;
 
                                      A-8
<PAGE>
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
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 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.
 
                                      A-10
<PAGE>
    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 June  30, 1994,  the  Insurer had  admitted assets  of $3.3
billion (unaudited), total  liabilities of $2.2  billion (unaudited), and  total
capital  and surplus of  $1.1 billion (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
 
                                      A-12
<PAGE>
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 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
 
                                      A-13
<PAGE>
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 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.  Any assumptions  regarding  maturity  made  for
purposes  of  determining the  appropriate  sales charge  in  no way  predict or
guarantee the actual remaining life of a given Trust.
 
    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
 
                                      A-14
<PAGE>
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.
 
    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.
 
                                      A-15

    The above graduated sales charges will apply on all applicable 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).
 
    Units  may be  purchased in  the primary or  secondary market  at the Public
Offering Price for  non-breakpoint purchases  minus the  concession the  Sponsor
typically  allows  to  brokers  and dealers  for  non-breakpoint  purchases (see
Section 17)  by  investors  who purchase  Units  through  registered  investment
advisers, certified financial planners and registered broker-dealers who in each
case  either charge periodic fees for financial planning, investment advisory or
asset management  services, or  provide  such services  in connection  with  the
establishment  of an  investment account  for which  a comprehensive  "wrap fee"
charge is imposed, and by bank trust departments investing funds over which they
exercise exclusive discretionary  investment authority  and that are  held in  a
fiduciary,  agency, custodial  or similar capacity.  Notwithstanding anything to
the contrary in this Prospectus, investors and bank trust departments purchasing
Units through this program will not receive sales charge reductions for quantity
purchases.
 
    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-16
<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-17
<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-18
<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.  A
Unitholder's  actual return may vary  significantly from the Estimated Long-Term
Return, based  on their  holding  period, market  interest rate  changes,  other
factors  affecting  the  prices  of  individual  bonds  in  the  portfolio,  and
differences between  the expected  remaining  life of  portfolio bonds  and  the
actual length of time that they remain in the Trust; such actual holding periods
may  be reduced  by termination  of the  Trust, as  described in  "AMENDMENT AND
TERMINATION OF  INDENTURE." 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.
 
                                      A-19
<PAGE>
    Taxpayers  must  disclose  on  their  Federal  tax  returns  the  amount  of
tax-exempt  interest  earned  during  the  year.  Federally  tax-exempt  income,
including  income on Units  of the Trusts,  will be taken  into consideration in
computing the portion, if any, of social security benefits received that will be
included in a taxpayer's gross income subject to the Federal income tax.
 
    Gain realized on the sale or redemption of the Bonds by the Trustee or of  a
Unit  by  a Unitholder  is includable  in  gross income  for Federal  income tax
purposes, and may be  includable in gross income  for state tax purposes.  (Such
gain  does not include  any amounts received  in respect of  accrued interest or
accrued original  issue  discount,  if  any.) It  should  be  noted  that  under
provisions  of the Revenue Reconciliation Act  of 1993 (the "Tax Act") described
below that subject accretion of market discount on tax-exempt bonds to  taxation
as  ordinary income,  gain realized on  the sale  or redemption of  Bonds by the
Trustee or of Units by a Unitholder that would have been treated as capital gain
under prior law is treated as ordinary  income to the extent it is  attributable
to  accretion of market discount.  Market discount can arise  based on the price
the Trust pays  for the  Bonds or the  price a  Unitholder pays for  his or  her
Units.
 
    In the opinion of Chapman and Cutler, Counsel to the Sponsor, under existing
law:
 
    (1) the  Trusts  are not  associations taxable  as corporations  for Federal
        income tax purposes. Tax-exempt interest received by each of the  Trusts
        on  Bonds  deposited  therein  will  retain  its  status  as  tax-exempt
        interest, for Federal income tax  purposes, when received by the  Trusts
        and  when distributed  to the  Unitholders, except  that the alternative
        minimum tax and  environmental tax (the  "Superfund Tax") applicable  to
        corporate  Unitholders  may, in  certain  circumstances, include  in the
        amount on which  such taxes  are calculated  a portion  of the  interest
        income  received by  the Trust. See  "Certain Tax  Matters Applicable to
        Corporate Unitholders", below;
 
    (2) each Unitholder of a Trust is considered  to be the owner of a pro  rata
        portion  of such Trust under Subpart E, subchapter J of Chapter 1 of the
        Internal Revenue Code of 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
 
                                      A-20
<PAGE>
        paid by the respective issuer provided  that, at the time such  policies
        are  purchased,  the  amounts  paid for  such  policies  are reasonable,
        customary and consistent with the reasonable expectation that the issuer
        of the bonds,  rather than  the insurer, will  pay debt  service on  the
        bonds. Paragraph (2) of this opinion is accordingly applicable to policy
        proceeds representing maturing interest.
 
In the opinion of Carter, Ledyard & Milburn, counsel to the Trustee, and, in the
absence  of a New York Trust from the Series, special counsel for the Series for
New York tax matters, under existing law:
 
        Under the income tax laws of the State and City of New York, each  Trust
    is  not an association taxable as a corporation and the income of each Trust
    will be treated as the income of the Unitholders.
 
    For a summary  of each opinion  of special counsel  to the respective  State
Trusts for state tax matters, see Section 3.
 
    ALL STATEMENTS IN THE PROSPECTUS CONCERNING EXEMPTION FROM FEDERAL, STATE OR
OTHER TAXES ARE THE OPINION OF COUNSEL AND ARE TO BE SO CONSTRUED.
 
    The  redemption of Units in a Trust by  a Unitholder would result in each of
the remaining Unitholders of said Trust owning a greater proportionate  interest
in  the remaining assets of  said Trust. Although present  law does not directly
address this matter, it  would appear reasonable  that a remaining  Unitholder's
tax  basis in his  Units would include  his proportionate share  of any proceeds
received by the Trust on the sale of bonds which were not distributed to him but
were instead used by  the Trust to redeem  Units and that his  tax basis in  the
remaining  assets of the Trust  would accordingly be increased  by such share of
proceeds, based on the relative fair market value of the remaining assets of the
Trust as of the date of such redemption.
 
    Sections 1288 and 1272 of the Code provide a complex set of rules  governing
the  accrual of original issue discount. These rules provide that original issue
discount accrues either  on the basis  of a constant  compound interest rate  or
ratably over the term of the Bond, depending on the date the Bond was issued. In
addition,  special  rules apply  if the  purchase  price of  a Bond  exceeds the
original issue price plus the amount of original issue discount which would have
previously accrued based upon its issue price (its "adjusted issue price").  The
application  of these rules will also vary depending on the value of the Bond on
the date a Unitholder 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
 
                                      A-21
<PAGE>
income  taxes, is not deductible. Because each Unitholder is treated for Federal
income tax purposes as the owner of a  pro rata share of the Bonds owned by  the
applicable  Trust, interest on borrowed funds used to purchase or carry Units of
such Trust will not be deductible  for Federal income tax purposes. Under  rules
used  by the  Internal Revenue Service  for determining when  borrowed funds are
considered used for the purpose of purchasing or carrying particular assets, the
purchase of Units may be considered to  have been made with borrowed funds  even
though  the borrowed funds are  not directly traceable to  the purchase of Units
(however, these rules generally  do not apply to  interest paid on  indebtedness
incurred  to  purchase  or  improve a  personal  residence).  Similar  rules are
generally applicable for state tax purposes. Special rules apply in the case  of
certain  financial  institutions that  acquire  Units. Investors  with questions
regarding these issues should consult with their tax advisers.
 
    In general,  each  issue  of bonds  in  the  Trusts is  subject  to  certain
post-issuance  requirements which must be  met in order for  the interest on the
Bonds to be and remain exempt from Federal income taxation. Bond counsel to each
issuer generally has opined that, assuming continuing compliance by such issuers
with certain covenants, interest on such  Bonds will continue to be exempt  from
Federal income taxation (other than with respect to the application to corporate
Unitholders  of the alternative  minimum tax or the  Superfund Tax, as discussed
below).
 
    For purposes of computing  the alternative minimum  tax for individuals  and
corporations, interest on certain specified tax-exempt private activity bonds is
included as a preference item. The Trusts do not include any such bonds.
 
    For  taxpayers  other than  corporations,  net capital  gains  are presently
subject to a maximum tax  rate of 28 percent. However,  it should be noted  that
legislative proposals are introduced from time to time that affect tax rates and
could affect relative differences at which ordinary income and capital gains are
taxed.
 
    CERTAIN  TAX MATTERS  APPLICABLE TO  CORPORATE UNITHOLDERS.  In the  case of
certain corporations, the alternative minimum  tax and the Superfund Tax  depend
upon the corporation's alternative minimum taxable income ("AMTI"), which is the
corporation's  taxable income  with certain  adjustments. One  of the adjustment
items used in computing AMTI and the Superfund Tax of a corporation (other  than
an S corporation, Regulated Investment Company, Real Estate Investment Trust, or
REMIC)  is an amount equal to 75%  of the excess of such 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
 
                                      A-22
<PAGE>
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 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
 
                                      A-23
<PAGE>
will be  made on  or shortly  after the  fifteenth day  of the  month.  Proceeds
received  from the disposition, including sale, call  or maturity, of any of the
Bonds and  all amounts  paid with  respect  to zero  coupon bonds  and  Stripped
Obligations  will be held  in the Principal  Account and either  used to pay for
Units redeemed  or  distributed on  the  Distribution Date  following  the  next
semi-annual Record Date. The Trustee is not required to make a distribution from
the  Principal Account of any Trust unless the amount available for distribution
in such account equals at least ten cents per Unit.
 
    The pro rata share of the Interest Account in each Trust will be computed by
the Trustee each month as of each Record Date and distributions will be made  on
or  shortly after the fifteenth day of the month to Unitholders of such Trust as
of the Record Date who are entitled to distributions at that time under the plan
of distribution chosen. Persons who purchase  Units between a Record Date and  a
Distribution Date will receive their first distribution on the Distribution Date
following the next Record Date under the applicable plan of distribution.
 
    Purchasers  of  Units  who desire  to  receive interest  distributions  on a
monthly or quarterly basis may elect to do so at the time of purchase during the
initial public offering  period. Those indicating  no choice will  be deemed  to
have  chosen the  semi-annual distribution  plan. All  Unitholders, however, who
purchase Units during the  initial public offering period  and who hold them  of
record on the first Record Date will receive the first distribution of interest.
Thereafter, Record Dates for monthly distributions will be the first day of each
month;  Record  Dates  for quarterly  distributions  will  be the  first  day of
February,  May,  August   and  November;  and   Record  Dates  for   semi-annual
distributions will be the first day of May and November.
 
    Details  of distributions  per Unit  of each  Trust under  the various plans
based upon estimated Net Annual Interest Income at the Date of Deposit are shown
in the tables appearing  in Section 3. The  amount of the regular  distributions
will  remain the same so long as each  Trust portfolio remains the same and 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
 
                                      A-24
<PAGE>
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.
 
    The  Trustee  shall withdraw  from the  Interest  Account and  the Principal
Account of a  Trust such amounts  as may  be necessary to  cover redemptions  of
Units of such Trust by the Trustee. (See Section 19.)
 
    Funds  which are available for future distributions, redemptions and payment
of expenses are held in accounts  which are non-interest bearing to  Unitholders
and are available for use by the Trustee pursuant to normal banking procedures.
 
14.  ACCUMULATION PLAN
 
The  Sponsor, John Nuveen & Co.  Incorporated, is also the principal underwriter
of the  Nuveen Municipal  Bond Fund,  Inc. (the  "Bond Fund"),  Nuveen  Tax-Free
Reserves, Inc. ("Tax-Free Reserves"), Nuveen California Tax-Free Fund, Inc. (the
"California  Fund"),  Nuveen Tax-Free  Bond Fund,  Inc. ("Tax-Free  Bond Fund"),
Nuveen Insured Tax-Free  Bond Fund, Inc.  (the "Insured Bond  Fund") and  Nuveen
Tax-Free  Money  Market Fund,  Inc.  (the "Money  Market  Fund") and  the Nuveen
Multistate  Tax-Free  Trust  (the  "Multistate  Trust").  Each  of  these  funds
(together,  the  "Accumulation Funds")  is  an open-end,  diversified management
investment  company  into  which  Unitholders  may  choose  to  reinvest   Trust
distributions  automatically,  without any  sales  charge. (Reinvestment  in the
California Fund is available only  to Unitholders who are California  residents.
Reinvestment in the State Portfolios of the Tax-Free Bond Fund, the Insured Bond
Fund,  the  Money Market  Fund and  the  Multistate Trust  is available  only to
Unitholders who  are residents  of  the states  for  which such  portfolios  are
named.)  Unitholders may reinvest  both interest and  principal distributions or
principal distributions only. Each  Accumulation Fund has investment  objectives
which  differ in  certain respects from  those of  the Trusts and  may invest in
securities which would not be eligible for deposit in the Trusts. The investment
adviser to  each Accumulation  Fund  is Nuveen  Advisory Corp.,  a  wholly-owned
subsidiary  of  the  Sponsor. The  following  is  a 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
 
                                      A-25
<PAGE>
Reserves  may  include in  its portfolio  municipal  obligations rated  Aaa, Aa,
MIG-1, VMIG-1  or Prime-1  by Moody's  or AAA,  AA, SP-1  or A-1  by Standard  &
Poor's,  unrated municipal  obligations that, in  the opinion  of the investment
adviser, have credit characteristics equivalent  to obligations rated as  above,
tax-exempt  obligations backed by the U.S. Government, and temporary investments
that may be subject to Federal income tax.
 
THE CALIFORNIA FUND
 
    The California Fund has  the objective of  providing, through investment  in
professionally managed portfolios of California municipal obligations, as high a
level  of current interest income exempt from both Federal and California income
taxes as is consistent with the investment policies of each of the portfolios of
the California Fund  and with  preservation of  capital. Each  portfolio of  the
California  Fund may include  temporary investments that may  be subject to tax.
California Unitholders may reinvest in one of three portfolios of the California
Fund: The Nuveen California Tax-Free  Value Fund, the Nuveen California  Insured
Tax-Free Value Fund and the Nuveen California Tax-Free Money Market Fund.
 
    The  Nuveen California  Tax-Free Value  Fund invests  primarily in long-term
investment grade  California tax-exempt  bonds (I.E.,  bonds rated  in the  four
highest  categories by Moody's  or Standard &  Poor's or, if  unrated, that have
equivalent credit characteristics). The Nuveen California Insured Tax-Free Value
Fund invests  primarily in  the same  type of  investments as  the Special  Bond
Portfolio, each of which is covered by insurance guaranteeing the timely payment
of  principal  and  interest  or  is backed  by  a  deposit  of  U.S. Government
securities.
 
    The Nuveen  California  Tax-Free  Money Market  Fund  invests  primarily  in
high-quality  short term  California tax-exempt money  market instruments (I.E.,
obligations rated in the two highest categories by Moody's or Standard &  Poor's
or,  if unrated,  that have  equivalent credit  characteristics). This portfolio
will include  only  obligations  maturing  within one  year  from  the  date  of
acquisition, will maintain an average maturity of all investments of 120 days or
less, will value its portfolio at amortized cost and will seek to maintain a net
asset 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
 
                                      A-26
<PAGE>
state for which the portfolio is named.) The Insured Bond Fund has the objective
of  providing,  through  investment  in  professionally  managed  portfolios  of
municipal  bonds, as high  a level of  current interest income  exempt from both
Federal income tax  and, in the  case of designated  state portfolios, from  the
income  tax imposed by each portfolio's  designated state, as is consistent with
preservation of  capital. The  Insured Bond  Fund  may include  in each  of  its
portfolios the same type of investments as the Tax-Free Bond Fund, each of which
is  covered  by  insurance  guaranteeing the  timely  payment  of  principal and
interest or is backed by a deposit of U.S. Government securities.
 
THE MONEY MARKET FUND
 
    The Money Market Fund  consists of the  Nuveen Massachusetts Tax-Free  Money
Market  Fund and the Nuveen New York  Tax-Free Money Market Fund, which are each
available for reinvestment  to Unitholders who  are residents of  the state  for
which  such portfolio is named. The Money Market Fund includes in its portfolios
only obligations  maturing  within  one  year  from  the  date  of  acquisition,
maintains  an average  maturity of  120 days or  less, values  its portfolios at
amortized cost and seeks to maintain a  net asset value of $1.00 per share.  The
Money  Market  Fund  has  the  objective  of  providing,  through  investment in
professionally  managed  portfolios   of  high   quality  short-term   municipal
obligations, as high a level of current interest income exempt both from Federal
income  tax and from the income tax imposed by each portfolio's designated state
as is consistent with stability of  principal and the maintenance of  liquidity.
The  Money  Market  Fund  may  include  in  each  of  its  portfolios  municipal
obligations rated Aaa, Aa, MIG-1, MIG-2, VMIG-1,  VMIG-2, Prime 1 or Prime 2  by
Moody's  or  AAA, AA,  SP-1,  SP-2, A-1  or A-2  by  Standard &  Poor's; unrated
municipal obligations  that, in  the  opinion of  the investment  adviser,  have
credit  characteristics equivalent to obligations  rated as above; and temporary
investments that may be subject to Federal and state income tax.
 
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
 
                                      A-27
<PAGE>
value as  computed  as  of  4:00  p.m. eastern  time  on  each  such  date.  All
distributions  will be  reinvested in the  Accumulation Fund chosen  and no part
thereof will be  retained in a  separate account. These  purchases will be  made
without a sales charge.
 
    Shareholder Services, Inc. will mail to each participant in the Accumulation
Plan  a quarterly  statement containing a  record of  all transactions involving
purchases of Accumulation Fund shares (or fractions thereof) with Trust interest
distributions or as a result of reinvestment of Accumulation Fund dividends. Any
distribution of principal used to purchase  shares of an Accumulation Fund  will
be  separately  confirmed by  Shareholder Services,  Inc. Unitholders  will also
receive  distribution  statements  from   the  Trustee  detailing  the   amounts
transferred to their Accumulation Fund accounts.
 
    Participants  may at any time, by so notifying the Trustee in writing, elect
to change  the  Accumulation  Fund  into which  their  distributions  are  being
reinvested,  to change from principal only  reinvestment to reinvestment of both
principal and interest or vice versa, or to terminate their participation in the
Accumulation Plan altogether and receive future distributions on their Units  in
cash.  There will be no  charge or other penalty for  such change of election or
termination.
 
    The character of  Trust distributions  for income tax  purposes will  remain
unchanged even if they are reinvested in an Accumulation Fund.
 
15.  HOW DETAILED ARE REPORTS TO UNITHOLDERS?
 
The  Trustee  shall  furnish Unitholders  of  a  Trust in  connection  with each
distribution, a statement of the amount of  interest and, if any, the amount  of
other  receipts (received  since the preceding  distribution) being distributed,
expressed in each case  as a dollar  amount representing the  pro rata share  of
each Unit of a Trust outstanding and a year to date summary of all distributions
paid  on said Units.  Within a reasonable period  of time after  the end of each
calendar year, the Trustee shall furnish to  each person who at any time  during
the  calendar  year was  a registered  Unitholder  of a  Trust a  statement with
respect to  such  Trust  (i)  as to  the  Interest  Account:  interest  received
(including  amounts  representing  interest  received  upon  any  disposition of
Bonds), and, except  for any  State Trust, the  percentage of  such interest  by
states  in which the issuers  of the Bonds are  located, deductions for fees and
expenses of such Trust, redemption of Units and the balance remaining after such
distributions and deductions,  expressed in  each case  both as  a total  dollar
amount  and as  a dollar  amount representing  the pro  rata share  of each Unit
outstanding on the  last business  day of  such calendar  year; (ii)  as to  the
Principal  Account: the dates of  disposition of any Bonds  and the net proceeds
received therefrom (excluding  any portion representing  accrued interest),  the
amount  paid for purchase of Replacement  Bonds, the amount paid upon redemption
of Units, deductions for  payment of applicable taxes  and fees and expenses  of
the  Trustee, and the balance remaining  after such distributions and deductions
expressed both as a total dollar amount and as a dollar amount representing  the
pro  rata  share of  each  Unit outstanding  on the  last  business day  of such
calendar year;  (iii)  a  list  of  the Bonds  held  and  the  number  of  Units
outstanding  on the last business day of such calendar year; (iv) the Unit Value
based upon the last computation thereof made during such calendar year; and  (v)
amounts actually distributed during such calendar year from the Interest Account
and  from  the Principal  Account, separately  stated,  expressed both  as total
dollar amounts and  as dollar amounts  representing the pro  rata share of  each
Unit outstanding.
 
    Each  annual statement will reflect pertinent  information in respect of all
plans of distribution so that Unitholders may be informed regarding the  results
of other plans of distribution.

16.  UNIT VALUE AND EVALUATION
 
The  value of each  Trust is determined by  the Sponsor on the  basis of (1) the
cash on hand in the Trust or moneys  in the process of being collected, (2)  the
value  of the Bonds in  the Trust based on  the BID prices of  the Bonds and (3)
interest  accrued  thereon   not  subject  to   collection,  LESS  (1)   amounts
representing  taxes or governmental charges payable out of the Trust and (2) the
accrued expenses of the Trust. The result of such computation is divided by  the
number  of Units of such  Trust outstanding as of  the date thereof to determine
the per Unit value ("Unit Value") of  such Trust. The Sponsor may determine  the
value  of the Bonds in each Trust (1) on  the basis of current BID prices of the
Bonds obtained from dealers or brokers who customarily deal in bonds  comparable
to  those held by the Trust, (2) if bid  prices are not available for any of the
Bonds, on the basis of bid prices for comparable bonds, (3) by causing the value
of the Bonds to be determined by  others engaged in the practice of  evaluating,
quoting  or appraising comparable bonds or (4)  by any combination of the above.
Although the Unit Value of each Trust is  based on the BID prices of the  Bonds,
the Units are sold initially to the public at the Public Offering Price based on
the OFFERING prices of the Bonds.
 
    Because  the insurance obtained  by the Sponsor  or by the  issuers of Bonds
with respect to  the Bonds in  the Insured  Trusts and with  respect to  insured
Bonds  in Traditional Trusts is effective so long as such Bonds are outstanding,
such insurance will be  taken into account in  determining the bid and  offering
prices  of such  Bonds and therefore  some value attributable  to such insurance
will be included in the value of Units of Trusts that include such Bonds.
 
17.  HOW UNITS OF THE TRUSTS ARE DISTRIBUTED TO THE PUBLIC
 
John Nuveen & Co. Incorporated is the Sponsor and sole Underwriter of the Units.
It is  the  intention  of  the  Sponsor  to  qualify  Units  of  National,  Long
Intermediate,  Intermediate, Short Intermediate  and Short Term  Trusts for sale
under the laws of  substantially all of  the states, 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.
 
    Registered  investment advisers, certified financial planners and registered
broker-dealers who  in  each case  either  charge periodic  fees  for  financial
planning,  investment  advisory or  asset management  services, or  provide such
services in connection with the establishment of an investment account for which
a comprehensive  "wrap  fee"  charge  is imposed,  and  bank  trust  departments
investing  funds  over which  they  exercise exclusive  discretionary investment
authority and  that  are held  in  a  fiduciary, agency,  custodial  or  similar
capacity,  are  not entitled  to receive  any dealer  concession for  primary or
secondary market purchases in which an investor purchases any number of Units at
the Public Offering Price for non-breakpoint purchases minus the concession  the
sponsor  typically allows  to brokers  and dealers  for non-breakpoint purchases
(see Section 6).
 
    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
 
                                      A-30
<PAGE>
Certificate  along with  a written  request that  the Units  represented by such
Certificate be held in book entry  form. Likewise, a Unitholder who holds  Units
in book entry form may obtain a Certificate for such Units by written request to
the  Trustee. Units may be held in denominations  of one Unit or any multiple or
fraction thereof. Fractions of Units are  computed to three decimal places.  Any
Certificates issued will be numbered serially for identification, and are issued
in  fully registered form, transferable  only on the books  of the Trustee. Book
entry Unitholders will  receive a  Book Entry  Position Confirmation  reflecting
their ownership.
 
    Certificates  for  Units will  bear an  appropriate  notation on  their face
indicating which plan of distribution has been selected. When a change is  made,
the   existing  Certificates  must  be  surrendered   to  the  Trustee  and  new
Certificates issued to  reflect the  currently effective  plan of  distribution.
There will be no charge for this service. Holders of book entry Units can change
their  plan of distribution  by making a  written request to  the Trustee, which
will issue a new Book Entry Position Confirmation to reflect such change.
 
    Units are transferable by  making a written request  to the Trustee and,  in
the  case of Units  evidenced by Certificate(s),  by presenting and surrendering
such Certificate(s) to the  Trustee, at its corporate  trust office in New  York
City, properly endorsed or accompanied by a written instrument or instruments of
transfer. The Certificate(s) should be sent registered or certified mail for the
protection  of the Unitholder.  Each Unitholder must  sign such written request,
and such Certificate(s) or transfer instrument,  exactly as his name appears  on
(a)  the face of the Certificate(s) representing the Units to be transferred, or
(b) the  Book  Entry  Position  Confirmation(s) relating  to  the  Units  to  be
transferred.  Such signature(s) must be guaranteed  by a 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
 
                                      A-31
<PAGE>
case of Units evidenced by a Certificate, by also tendering such Certificate  to
the Trustee, duly endorsed or accompanied by proper instruments of transfer with
signatures  guaranteed  as explained  in Section  18 above,  and (3)  payment of
applicable governmental charges,  if any.  Certificates should be  sent only  by
registered  or certified mail to minimize the possibility of their being lost or
stolen. In order to effect a redemption  of Units evidenced by a Certificate,  a
Unitholder  must tender the  Certificate to the  Trustee or provide satisfactory
indemnity required in  connection with  lost, stolen  or destroyed  Certificates
(See  Section 18). No redemption fee will be charged. A Unitholder may authorize
the Trustee to honor telephone instructions for the redemption of Units held  in
book  entry  form. Units  represented  by Certificates  may  not be  redeemed by
telephone. The proceeds  of Units redeemed  by telephone will  be sent by  check
either  to  the Unitholder  at  the address  specified on  his  account or  to a
financial institution specified by the Unitholder  for credit to the account  of
the  Unitholder.  A Unitholder  wishing to  use this  method of  redemption must
complete a Telephone Redemption Authorization Form  and furnish the Form to  the
Trustee.  Telephone  Redemption  Authorization  Forms  can  be  obtained  from a
Unitholder's registered  representative  or by  calling  the Trustee.  Once  the
completed  Form is on file, the Trustee will honor telephone redemption requests
by any person.  If the telephone  redemption request is  received prior to  4:00
p.m.  eastern time,  the Unitholder  will be entitled  to receive  for each Unit
tendered the  Redemption  Price  as determined  above.  A  telephone  redemption
request  received after 4:00  p.m. eastern time  will be treated  as having been
received the  following business  day. The  redemption proceeds  will be  mailed
within seven calendar days following the telephone redemption request. Telephone
redemptions  are limited to 1,000 Units or less.  Only Units held in the name of
individuals may be redeemed by telephone; accounts registered in broker name, or
accounts of  corporations  or  fiduciaries (including  among  others,  trustees,
guardians,  executors and administrators)  may not use  the telephone redemption
privilege.
 
    On the seventh calendar day following the date of tender, or if the  seventh
calendar day is not a business day, on the first business day prior thereto, the
Unitholder  will be entitled to receive in cash for each Unit tendered an amount
equal to the Unit Value of such Trust determined by the Trustee, as of 4:00 p.m.
eastern time on the date of  tender as defined hereafter, plus accrued  interest
to,  but  not  including,  the  fifth business  day  after  the  date  of tender
("Redemption Price"). The  price received upon  redemption may be  more or  less
than  the amount paid by  the Unitholder depending on the  value of the Bonds on
the date of  tender. Such  value will vary  with market  and credit  conditions,
including  changes in  interest rate levels.  Unitholders should  check with the
Trustee or  their broker  to  determine the  Redemption Price  before  tendering
Units.
 
    While the Trustee has the power to determine Redemption Price when Units are
tendered,  the authority has by  practice been delegated by  the Trustee to John
Nuveen & Co.  Incorporated, which  determines the  Redemption Price  on a  daily
basis.
 
    The  "date of  tender" is  deemed to be  the date  on which  the request for
redemption of Units is received  in proper form by  the Trustee, except that  as
regards a redemption request 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.
 
                                      A-32
<PAGE>
    To  the extent that Bonds  are sold from a Trust,  the size and diversity of
such Trust will  be reduced. Such  sales may be  required at a  time when  Bonds
would  not  otherwise  be sold  and  might  result in  lower  prices  than might
otherwise be realized.
 
    The Redemption Price is  determined on the  basis of the  BID prices of  the
Bonds  in each Trust, while  the initial Public Offering  Price of Units will be
determined on the  basis of the  OFFERING prices of  the Bonds as  of 4:00  p.m.
eastern  time on any day on which the  Exchange is normally open for trading and
such determination is made. As of any given time, the difference between the bid
and offering  prices of  such Bonds  may  be expected  to average  1% to  2%  of
principal  amount in the case of Bonds  in National, Long Intermediate and State
Trusts, 3/4%  to  1  1/2% in  the  case  of Bonds  in  Intermediate,  and  Short
Intermediate  Trusts and 1/2% to 3/4% in the case of Bonds in Short Term Trusts.
In the case of actively traded Bonds, the difference may be as little as 1/4  to
1/2  of 1%, and in  the case of inactively  traded Bonds such difference usually
will not exceed 3%. The difference between the aggregate offering prices of  the
Bonds  in each Trust  and the aggregate  bid prices thereof  on the business day
prior to  the Date  of Deposit  is shown  in the  discussion of  specific  trust
matters.
 
    The  right  of redemption  may be  suspended and  payment postponed  for any
period during  which  the Securities  and  Exchange Commission  determines  that
trading  in the municipal bond market is restricted or an emergency exists, as a
result  of  which  disposal  or  evaluation  of  the  Bonds  is  not  reasonably
practicable, or for such other periods as the Securities and Exchange Commission
may by order permit.
 
    Under  regulations issued by the Internal  Revenue Service, the Trustee will
be required to withhold 31% of the principal amount of a Unit redemption if  the
Trustee  has not  been furnished  the redeeming  Unitholder's tax identification
number in the  manner required by  such regulations. Any  amount so withheld  is
transmitted  to  the  Internal  Revenue  Service and  may  be  recovered  by the
Unitholder only when filing  his or her tax  return. Under normal  circumstances
the  Trustee obtains the Unitholder's tax identification number from the selling
broker at the time the Certificate or Book Entry Return Confirmation is  issued,
and  this number is printed on the Certificate or Book Entry Return Confirmation
and on distribution statements. If a Unitholder's tax identification number does
not appear as  described above,  or if it  is incorrect,  the Unitholder  should
contact  the Trustee before redeeming Units to determine what action, if any, is
required to avoid this "back-up withholding."
 
20.  HOW UNITS MAY BE PURCHASED BY THE SPONSOR
 
The Trustee will notify the  Sponsor of any tender  of Units for redemption.  If
the  Sponsor's bid in  the secondary market  at that time  equals or exceeds the
Redemption Price it may purchase such Units by notifying the Trustee before  the
close  of business on the  second succeeding business day  and by making payment
therefor to  the  Unitholder not  later  than the  day  on which  payment  would
otherwise have been made by the Trustee. (See Section 19.) The Sponsor's current
practice  is to bid at the Redemption  Price in the secondary market. Units held
by the Sponsor may be tendered to the Trustee for redemption as any other Units.
 
    The Public Offering  Price upon  resale of any  Units thus  acquired by  the
Sponsor  will be  calculated in accordance  with the procedure  described in the
then currently effective prospectus relating to such Units. Any profit resulting
from the resale of  such Units will  belong to the  Sponsor which likewise  will
bear  any loss resulting from a lower  Public Offering Price or Redemption Price
subsequent to its acquisition of such Units.

21.  HOW BONDS MAY BE REMOVED FROM THE TRUSTS
 
Bonds will be removed from a Trust as they mature or are redeemed by the issuers
thereof. See  the "Schedules  of Investments"  and "General  Trust  Information"
under Section 3 for a discussion of call provisions of portfolio Bonds.
 
    The  Indenture also empowers  the Trustee to  sell Bonds for  the purpose of
redeeming Units tendered by any Unitholder, and for the payment of expenses  for
which  income may not be available. Under the Indenture the Sponsor is obligated
to provide the Trustee with a current list of Bonds in each Trust to be sold  in
such  circumstances. In deciding which Bonds  should be sold the Sponsor intends
to consider, among  other things, such  factors as: (1)  market conditions;  (2)
market  prices  of  the  Bonds;  (3)  the  effect  on  income  distributions  to
Unitholders of the sale of various Bonds; (4) the effect on principal amount  of
underlying  Bonds  per Unit  of the  sale  of various  Bonds; (5)  the financial
condition of the issuers; and (6) the effect of the sale of various Bonds on the
investment character of the Trust. Such sales, if required, could result in  the
sale  of Bonds by the Trustee at prices less than original cost to the Trust. To
the extent Bonds are sold, the size and diversity of such Trust will be reduced.
 
    In addition, the  Sponsor is empowered  to direct the  Trustee to  liquidate
Bonds upon the happening of certain other events, such as default in the payment
of principal and/or interest, an action of the issuer that will adversely affect
its  ability to continue payment of the  principal of and interest on its Bonds,
or an  adverse  change  in  market, revenue  or  credit  factors  affecting  the
investment  character of the Bonds. If a default in the payment of the principal
of and/or interest  on any  of the  Bonds occurs, and  if the  Sponsor fails  to
instruct  the Trustee whether to  sell or continue to  hold such Bonds within 30
days after  notification by  the Trustee  to the  Sponsor of  such default,  the
Indenture  provides that  the Trustee shall  liquidate said  Bonds forthwith and
shall not be liable for any loss so incurred.
 
    In connection with its  determination as to the  sale or liquidation of  any
Bonds,  the Sponsor  will consider the  Bond's then current  rating, but because
such ratings are the opinions of the rating agencies as to the quality of  Bonds
they  undertake to rate and not absolute  standards of quality, the Sponsor will
exercise its independent judgment as to Bond creditworthiness.
 
    The Sponsor may also direct the Trustee to liquidate Bonds in a Trust if the
Bonds in  the  Trust  are  the  subject  of  an  advanced  refunding,  generally
considered  to be when refunding  bonds are issued and  the proceeds thereof are
deposited in irrevocable trust to retire the refunded Bonds on their  redemption
date.
 
    Except as stated in Section 4 regarding the limited right of substitution of
Replacement Bonds for Failed Bonds, and except for refunding securities that may
be  exchanged for Bonds under certain conditions specified in the Indenture, the
Indenture does  not permit  either the  Sponsor  or the  Trustee to  acquire  or
deposit  bonds either in addition  to, or in substitution  for, any of the Bonds
initially deposited in a Trust.
 
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

handling  of certain  Bonds deposited  in the  Trusts, the  Trustee may  use the
services of The
 
                                      A-34

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

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

24.  OTHER INFORMATION
AMENDMENT OF INDENTURE
 
    The Indenture may  be amended  by the Trustee  and the  Sponsor without  the
consent  of any of  the Unitholders (1) to  cure any ambiguity  or to correct or
supplement any provision thereof which may be defective or inconsistent, or  (2)
to  make such  other provisions as  shall not adversely  affect the Unitholders,
provided, however, that the Indenture may not be amended to increase the  number
of Units in any Trust or to permit the deposit or acquisition of bonds either in
addition  to, or in substitution for any of the Bonds initially deposited in any
Trust except as stated in Section 4 regarding the limited right of  substitution
of  Replacement Bonds and  except for the substitution  of refunding bonds under
certain circumstances. The Trustee shall advise the Unitholders of any amendment
promptly after execution thereof.
 
TERMINATION OF INDENTURE
 
    Each Trust may be liquidated at any  time by written consent of 100% of  the
Unitholders  or by  the Trustee when  the value of  such Trust, as  shown by any
evaluation, is less than 20% of the original principal amount of such Trust  and
will  be  liquidated  by  the Trustee  in  the  event that  Units  not  yet sold
aggregating more  than 60%  of the  Units originally  created are  tendered  for
redemption  by the Sponsor thereby reducing the  net worth of such Trust to less
than 40%  of the  principal amount  of  the Bonds  originally deposited  in  the
portfolio. (See "Essential Information Regarding the Trusts.") The sale of Bonds
from  the Trusts upon termination  may result in realization  of a lesser amount
than might otherwise be realized  if such sale were  not required at such  time.
For  this  reason,  among  others,  the amount  realized  by  a  Unitholder upon
termination  may  be  less  than  the  principal  amount  of  Bonds   originally
represented  by the Units held by  such Unitholder. The Indenture will terminate
upon the redemption, sale or other disposition of the last Bond held thereunder,
but in no event shall it continue beyond the end of the calendar year  preceding
the  fiftieth anniversary of its execution for National and State Trusts, beyond
the end  of  the  calendar  year preceding  the  twentieth  anniversary  of  its
execution  for Long Intermediate,  and Intermediate Trusts or  beyond the end of
the calendar year  preceding the tenth  anniversary of its  execution for  Short
Intermediate and Short Term Trusts.
 
    Written  notice of  any termination  specifying the  time or  times at which
Unitholders may surrender their Certificates, if any, for cancellation shall  be
given  by  the  Trustee to  each  Unitholder  at the  address  appearing  on the
registration books of the Trust maintained by the
 
                                      A-37
<PAGE>
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.

                                      A-39
<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

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.

multiple "dagger".  The "dagger" symbol is represented as # in the electronic
document.

John Nuveen & Co. Incorporated
333 W. Wacker Drive
Chicago, Illinois  60606
RE:  Nuveen Tax-Exempt Unit Trust, Series 767

Gentlemen:

    We have served as counsel for you, as Depositor of Nuveen Tax-Exempt Unit
Trust, Series 767 (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 767.

    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, provided that, at the time such policies are purchased,
the amounts paid for such policies are reasonable, customary and consistent
with the reasonable expectation that the issuer of the bonds, rather than
the insurer, will pay debt service on the bonds.  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(c) 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. 33-56347) 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.

Nuveen Tax-Exempt Unit Trust,
Series 767 - North Carolina Traditional 282
John Nuveen & Co. Incorporated
333 West Wacker Drive
Chicago, Illinois 60606

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

United States Trust Company of New York,
as Trustee of Nuveen Tax-Exempt Unit Trust,
Series 767 - North Carolina Traditional Trust 282
770 Broadway
New York, New York 10003

Gentlemen:

    We have acted as special North Carolina counsel to Nuveen Tax-Exempt Unit
Trust, Series 767 (the "Fund") concerning a Registration Statement (No.
33-56347) on Form S-6 under the Securities Act of 1933, as amended (the
"Registration Statement"), in connection with the issuance by the Fund of 
units of fractional undivided interests in the Fund (the "Units").  The Fund
has been organized under a Trust Indenture and Agreement, dated of even date 
hereof, between John Nuveen & Co., Incorporated (the "Depositor") and United 
States Trust Company of New York (the "Trustee").  The Fund will issue the 
Units in several unit investment trusts for designated states, one of which 
will be North Carolina Traditional Trust 282  (the "Trust").  The Units
will be purchased by various investors (the "Unitholders").  Each Unit of the
Trust represents a fractional undivided interest in the principal and net
income of the Trust in the ratio of 10 Units for each $1,000 principal amount 
of the obligations initially acquired by the Trust.  Each 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 North Carolina, its political 
subdivisions authorities and provided the interest thereon is exempt
from North Carolina 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, the Virgin Islands, Guam and the Northern Mariana Islands), their
political subdivisions and authorities (the "Bonds").  Distributions of the
interest received by the Trust will be made semiannually unless the
Unitholder elects otherwise.
 
    You have requested our opinion as to the application of North Carolina 
state and local taxes to the Trust and the Unitholders.  In rendering
our opinion, we have assumed (i) that the interest on all Bonds in the Trust 
will be exempt from Federal income tax and (ii) that the Bonds have been
issued in strict compliance with all requirements of North Carolina law or, 
where applicable, Federal or territorial law.  Furthermore, in rendering our
opinion, we have relied on the opinion of Messrs. Chapman and Cutler, of even
date herewith, that:

    (i) 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 (the "Code");

    (ii)  Each Unitholder will be considered the owner of a pro rata
portion 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 Code;

    (iii)  The Trust, itself, will not be subject to federal income taxes;

    (iv)  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.  Accord-
ingly, to the extent that the income of the Trust consists of interest exclud-
able from federal gross income, such income will be excludable from the
federal gross income of the Unitholder; and

    (v)  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 Trust.

<PAGE>

    Based upon the foregoing and under existing law, we are of the opinion 
that:

    (1)  The Trust is not an association taxable as a corporation for North
Carolina income tax purposes.

    (2)  Interest on the Bonds which is exempt from North Carolina income tax
when received by the Trust will retain its status as tax-exempt interest when
distributed to Unitholders.

    (3)  For North Carolina income tax purposes, each Unitholder will
have a taxable event when, upon redemption or sale of his Unit, he receives 
cash or other property.  Gain or loss will be determined by computing the 
difference between the proceeds of such a redemption or sale and the 
Unitholder's adjusted basis for the Unit.

    (4)  For North Carolina income tax purposes, each Unitholder will
have a taxable event when the Trust disposes of one of the Bonds (whether by
sale, payment at maturity, retirement or otherwise); provided that when any of
the Bonds held by the Trust have been issued under an act of the General
Assembly of North Carolina that provides that all income from such Bond,
including a profit made from the sale thereof, shall be free from all taxation
by the State of North Carolina, any such profit received by the Trust will
retain its tax-exempt status in the hands of each Unitholder.

    (5)  Ownership of the Units representing a pro rata ownership of the Bonds
is exempt from the North Carolina tax on intangible personal property so long 
as the corpus of the Trust is composed entirely of North Carolina obligations 
or is composed entirely of obligations of the United States and its
possessions and North Carolina and at least eighty percent (80%) of the fair
market value of such obligations represents North Carolina obligations;
provided that for this exemption to apply, the Trustee must periodically
provide to the North Carolina Department of Revenue such information about
the Trust as required by applicable law.
 
    (6)  Interest on indebtedness paid or accrued by a Unitholder in connect-
ion with ownership of Units in the Trust will not be deductible by the
Unitholder for North Carolina income tax purposes.

    (7)  Amortization of Bond premiums is mandatory for North Carolina state
income tax purposes for all North Carolina resident Unitholders.
Amortization for the taxable year is accomplished by lowering the basis or
adjusted basis of the Units, with no deduction against gross income for the
year.

    (8)  Trust Units will be subject to North Carolina inheritance and estate
tax if owned by a North Carolina resident on the date of his death.

    (9)  Neither the Bonds nor the Units in the Trust will be subject to the
North Carolina sales tax or use tax.

    The foregoing opinion, which is based on the applicable law at the date of
this letter and on information provided to us by the Depositor, is an opinion
of counsel only and cannot be relied upon as binding on the State of North
Carolina or its taxing authorities.  This opinion is dependent upon laws,
regulations and administrative and judicial decisions that are subject to
change.  This opinion is being rendered to you and the Unitholders solely
for their benefit in connection with the purchase of the Units and may not
be relied upon by any other person or for any other purpose without our
prior written consent.

    This letter is not to be construed as a prediction of a favorable outcome
with respect to any issue for which no favorable prediction is made herein, or
as a guaranty of any tax result, or as offering an assurance or guaranty that 
a North Carolina state taxing authority might not differ with our 
conclusions, or raise other questions or issues upon audit.

    We have not examined any of the Bonds to be deposited in the Fund and held
by the Trust, and 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 and to the reference to our firm in such Registration

EXHIBIT 3.3

(ON PITNEY, HARDIN, KIPP & SZUCH LETTERHEAD)

11/18/94

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

RE:  Nuveen Tax-Exempt Unit Trust, Series 767
      
     New Jersey Insured Trust 183

Gentlemen:

    We have acted as special counsel, with respect to New Jersey state tax
matters, to Nuveen Tax-Exempt Unit Trust, Series 767 (the "Fund")
concerning a Registration Statement (No. 33-56347) on Form S-6 under the
Securities Act of 1933, as amended, covering the issuance by the Fund of units
of fractional undivided interest (the "Units") in several state trusts (the
"State Trusts"), one of which is the above-captioned trust ("New
Jersey Trust").  Such Units will be purchased by various investors
("Unitholders").

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

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

<PAGE>

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

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

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

Very truly yours,



Pitney, Hardin, Kipp & Szuch

Re:     NUVEEN TAX EXEMPT UNIT TRUST, SERIES 767

        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 # 33-56347.

        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.
