NUVEEN  Tax-Exempt Unit Trusts
             PROSPECTUS
            Series 772
             December 7, 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  772 consists  of  three  underlying
separate  unit investment trusts designated  as North Carolina Traditional Trust
283, California Insured  Trust 237  and Florida  Insured Trust  202. 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 772
    
 
   
1.  WHAT IS THE NUVEEN TAX-EXEMPT UNIT TRUST, SERIES 772?
    
 
   
Series 772 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  283,  California
Insured  Trust  237  and  Florida  Insured Trust  202.  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  December 7, 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  $10,500,000 (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,
$3,500,000 in the California Insured Trust and $3,500,000 in the Florida 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, 35,000 Units of the California  Insured
Trust  and 35,000 Units  of the Florida Insured  Trust, which together represent
ownership of  the  entire  Series,  and  which are  offered  for  sale  by  this
Prospectus.  Each Unit of a Trust  represents a fractional undivided interest in
the principal and net  income of such Trust  in the ratio of  10 Units for  each
$1,000 principal value of Bonds initially deposited in such Trust.
    
 
2.  WHAT ARE THE OBJECTIVES OF THE TRUSTS?
 
The  objectives of the Trusts are income  exempt from Federal income tax and, in
the case of State Trusts, where applicable, state income and intangibles  taxes,
and  conservation of capital, through an  investment in obligations issued by or
on behalf of  states and territories  of the United  States and authorities  and
political  subdivisions thereof,  the interest  on which  is, in  the opinion of
recognized bond counsel  to the  issuing governmental  authorities, exempt  from
Federal income tax under existing law. Bonds in any State Trust have been issued
primarily  by  or on  behalf of  the State  for  which such  Trust is  named and
counties, municipalities, authorities  and political  subdivisions thereof,  the
interest  on which Bonds is, in the opinion of bond counsel, exempt from Federal
and certain state income tax and  intangibles taxes, if any, for purchasers  who
qualify  as residents of that State.  Insurance guaranteeing the timely payment,
when due, of all principal and interest  on the Bonds in each Insured Trust  has
been obtained by the Sponsor or by the issuers of such Bonds from Municipal Bond
Investors  Assurance  Corporation,  and  as  a  result  of  such  insurance  the
obligations in the Insured Trusts are rated "Aaa" by Moody's Investors  Service,
Inc. and "AAA" by Standard & Poor's Corporation. (SEE SECTION 5) All obligations
in each Traditional Trust are rated in the category "A" or better (SP-1 or MIG 2
or  better  in the  case  of short  term obligations  included  in a  Short Term
Traditional Trust)  by  Standard  &  Poor's  Corporation  or  Moody's  Investors
Service,  Inc.  (including  provisional or  conditional  ratings).  In addition,
certain Bonds  in  certain  Traditional  Trusts  may  be  covered  by  insurance
guaranteeing  the timely payment, when due,  of all principal and interest. (SEE
SECTION 3.) The  portfolios of National  and State Trusts  consist of  long-term
(approximately 15 to 40 year maturities) obligations; those of Long Intermediate
Trusts  consist  of  intermediate to  long  term  (approximately 11  to  19 year
 
                                       6
<PAGE>
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 283
    
   
    The  Portfolio  of  North  Carolina  Traditional  Trust  283  consists  of 8
obligations issued by  entities located in  North Carolina. Three  Bonds in  the
Trust  are general obligations of the governmental entities issuing them and are
backed by the taxing powers thereof. Five  Bonds in the Trust are payable as  to
principal  and interest from the  income of a specific  project or authority and
are not supported by the  issuer's power to levy  taxes. The sources of  payment
for  these Bonds  are divided as  follows: Electrical System  Revenue, 1; Health
Care Facility Revenue, 2; Municipal Lease Revenue, 2. Eight issues in the  Trust
were  rated by Standard  & Poor's Corporation as  follows: 5--AAA, 2--A+, 1--A-.
Eight issues were rated by Moody's  Investors Service, Inc. as follows:  5--Aaa,
2--A1, 1--A.
    
   
    At  the Date  of Deposit,  the average  maturity of  the Bonds  in the North
Carolina Traditional Trust is 20.0 years. The average maturity of the Bonds in a
Trust is calculated based upon the stated maturities of the Bonds in such  Trust
(or,  with respect to  Bonds for which  funds or securities  have been placed in
escrow to redeem such Bonds on a  stated call date, based upon such call  date).
The  average maturity of the Bonds in a Trust may increase or decrease from time
to time as Bonds mature or are called or sold.
    
 
   
    Approximately 28.6% of the  aggregate principal amount of  the Bonds in  the
Trust (accounting for approximately 26.8% of the aggregate offering price of the
Bonds)    are   original    issue   discount    bonds.   See    "GENERAL   TRUST
INFORMATION--ORIGINAL ISSUE  DISCOUNT  BONDS  AND STRIPPED  OBLIGATIONS"  for  a
discussion  of the  characteristics of  such bonds  and of  the risks associated
therewith.
    
 
    Approximately 29% of  the aggregate  principal amount  of the  Bonds in  the
Trust  are  obligations of  issuers whose  revenues  are primarily  derived from
municipal lease obligations. 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. Fourteen percent of
the aggregate principal amount of the  Bonds, included in the above amount,  are
obligations of issuers whose revenues are primarily derived from municipal lease
obligations, but which are covered by such insurance.
 
    Approximately  26% 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 11% 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 on December 6, 1994.
The  following summarizes certain information about the Bonds as of the business
day prior to the Date of Deposit:

    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 North Carolina Traditional Trust,  less estimated expenses, is estimated  to
accrue  at the rate  of $.01558 per Unit  per day under  the semi-annual plan of
distribution, $.01552 per Unit per day under the quarterly plan of  distribution
and  $.01543 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:
 
                                       9
<PAGE>
        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.
 
        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).
 
                                       10
<PAGE>
    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.
 
    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.

CALIFORNIA INSURED TRUST 237
    
 
   
    The  Portfolio of  California Insured  Trust 237  consists of  7 obligations
issued by entities located in California and one obligation issued by an  entity
located  in the  Territory of Puerto  Rico. One Bond  in the Trust  is a general
obligation of the  governmental entity issuing  it and is  backed by the  taxing
power thereof. Seven Bonds in the Trust are payable as to principal and interest
from  the income of a specific project or authority and are not supported by the
issuer's power to levy taxes. The sources of payment for these Bonds are divided
as follows:  Electrical System  Revenue,  2; Health  Care Facility  Revenue,  2;
Municipal  Lease Revenue, 2; Water and/or Sewer  Revenue, 1. All of the Bonds in
the Trust, as insured, are rated AAA by Standard & Poor's Corporation and Aaa by
Moody's Investors Service, Inc.
    
 
   
    At the Date of Deposit, the average maturity of the Bonds in the  California
Insured  Trust is 27.4  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 22% of  the aggregate  principal amount  of the  Bonds in  the
Trust consists of municipal lease obligations.
 
    Approximately  30% of  the aggregate  principal amount  of the  Bonds in the
Trust consists of obligations  of issuers whose  revenues are primarily  derived
from services provided by hospitals or other health care facilities.
 
    For  a discussion of the  risks associated with investments  in the bonds of
various issuers, see "General Trust Information" in this section.
 
   
    The Sponsor entered into contracts to acquire the Bonds on December 6, 1994.
The following summarizes certain information about the Bonds as of the  business
day prior to the Date of Deposit:

    Neither   cost  to  Sponsor  nor  profit   (or  loss)  to  Sponsor  reflects
underwriting profits or losses received or  incurred by the Sponsor through  its
participation   in  underwriting  syndicates.  An  underwriter  or  underwriting
syndicate purchases bonds  from the issuer  on a negotiated  or competitive  bid
basis  as principal with  the motive of  marketing such bonds  to investors at a
profit. The Sponsor did not participate as  either the sole underwriter or as  a
manager  or member of a syndicate that  acted as the original underwriter of any
of the Bonds.
 
   
    Unitholders may  elect to  have interest  distributions made  on a  monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the California Insured Trust, less estimated expenses, is estimated to accrue at
the rate of $.01635 per Unit per day under the semi-annual plan of distribution,
$.01630  per Unit per day  under the quarterly plan  of distribution and $.01621
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

TAX STATUS--CALIFORNIA INSURED TRUST
 
    For  a discussion of the  Federal tax status of  income earned on California
Insured Trust Units, see Section 11.
 
    In the opinion of Orrick, Herrington & Sutcliffe, special California counsel
to the Series, under existing California income and property tax law  applicable
to individuals who are California residents:
 
        The  California  Insured  Trust  is  not  an  association  taxable  as a
    corporation and the income of the  California Insured Trust will be  treated
    as the income of the Unitholders under the income tax laws of California.
 
        Interest  on the underlying securities (which may include bonds or other
    obligations issued by the  governments of Puerto  Rico, the Virgin  Islands,
    Guam  or  the  Northern Mariana  Islands)  which  is exempt  from  tax under
    California personal income tax  and property tax laws  when received by  the
    California  Insured  Trust  will,  under such  laws,  retain  its  status as
    tax-exempt interest when  distributed to Unitholders.  However, interest  on
    the  underlying securities attributed to a Unitholder which is a corporation
    subject to the California franchise tax laws may be includable in its  gross
    income for purposes of determining its California franchise tax.
 
        Under  California  income tax  law,  each Unitholder  in  the California
    Insured Trust will have  a taxable event when  the California Insured  Trust
    disposes  of a security (whether by sale, exchange, redemption or payment at
    maturity) or when  the Unitholder  redeems or  sells Units.  Because of  the
    requirement  that tax cost basis be  reduced to reflect amortization of bond
    premium, under some circumstances a
 
                                       15
<PAGE>
    Unitholder may realize taxable gain when  Units are sold or redeemed for  an
    amount  equal to, or less  than, their original cost.  The total tax cost of
    each Unit to a Unitholder is allocated among each of the bond issues held in
    the California  Insured Trust  (in  accordance with  the proportion  of  the
    California Insured Trust comprised by each bond issue) in order to determine
    his  per  unit tax  cost for  each bond  issue; and  the tax  cost reduction
    requirements relating to amortization of bond premium will apply  separately
    to  the per unit cost of each bond issue. Unitholders' bases in their Units,
    and the bases for their fractional interest in each California Insured Trust
    asset, may have to be adjusted for their pro rata share of accrued  interest
    received,  if any, on securities delivered after the Unitholders' respective
    settlement dates.
 
        Under the California  personal property tax  laws, bonds (including  the
    bonds  in  the  California  Insured  Trust  as  well  as  "regular-way"  and
    "when-issued" contracts for the purchase  of bonds) or any interest  therein
    is exempt from such tax.
 
        Any  proceeds paid under  the insurance policy issued  to the Trustee of
    the fund with respect to the bonds  in the California Insured Trust as  well
    as "regular-way" and "when-issued" contracts for the purchase of bonds which
    represent  maturing interest  on defaulted  obligations held  by the Trustee
    will be  exempt from  California personal  income tax  if, and  to the  same
    extent  as, such interest would have been so exempt if paid by the issuer of
    the defaulted obligations.
 
        Under Section 17280(b)(2) of the  California Revenue and Taxation  Code,
    interest on indebtedness incurred or continued to purchase or carry Units of
    the  California  Insured Trust  is not  deductible for  the purposes  of the
    California personal  income  tax. While  there  presently is  no  California
    authority  interpreting  this  provision,  Section  17280(b)(2)  directs the
    California Franchise  Tax Board  to  prescribe regulations  determining  the
    proper  allocation and apportionment of interest costs for this purpose. The
    Franchise Tax Board has not yet proposed or prescribed such regulations.  In
    interpreting  the generally similar Federal  provision, the Internal Revenue
    Service has taken the position that  such indebtedness need not be  directly
    traceable to the purchase or carrying of Units (although the Service has not
    contended that a deduction for interest on indebtedness incurred to purchase
    or  improve  a  personal residence  or  to  purchase goods  or  services for
    personal consumption  will be  disallowed). In  the absence  of  conflicting
    regulations  or  other California  authority,  the California  Franchise Tax
    Board generally  has  interpreted  California statutory  tax  provisions  in
    accord  with  Internal Revenue  Service  interpretations of  similar Federal
    provisions.
 
ECONOMIC FACTORS--CALIFORNIA
 
    As described  above, except  to the  extent the  Fund invests  in  temporary
investments,  the Fund will invest substantially all of its assets in California
Municipal Obligations. The Fund is therefore susceptible to political,  economic
or  regulatory factors  affecting issuers  of California  Municipal Obligations.
These include the possible adverse effects of certain California  constitutional
amendments,  legislative measures, voter initiatives  and other matters that are
described below. The following information provides only a brief summary of  the
complex  factors affecting the  financial situation in  California (the "State")
and is derived from  sources that are generally  available to investors and  are
believed  to  be accurate.  No  independent verification  has  been made  of the
accuracy or completeness  of any of  the following information.  It is based  in
part on information obtained from various State and
 
                                       16
<PAGE>
local  agencies in  California or contained  in Official  Statements for various
California Municipal Obligations.
 
    There can  be  no  assurance  that future  statewide  or  regional  economic
difficulties,  and the resulting impact on  State or local governmental finances
generally, will not adversely  affect the market  value of California  Municipal
Obligations  held in  the portfolio  of the  Fund or  the ability  of particular
obligors to  make timely  payments of  debt service  on (or  relating to)  those
obligations.
 
ECONOMIC OVERVIEW
 
    California's  economy is  the largest  among the  50 states  and one  of the
largest in the  world. The State's  population of almost  32 million  represents
12.3%  of the total United States population and grew by 27% in the 1980s. Total
personal income in the State, at an estimated $662 billion in 1992, accounts for
13% of all personal income in the nation. Total employment is almost 14 million,
the majority of which is in the service, trade and manufacturing sectors.
 
    Reports issued by the State Department of Finance and other sources indicate
that the State's economy is suffering its worst recession since the 1930s,  with
prospects  for recovery  slower than for  the nation  as a whole.  The State has
experienced the worst job losses in any postwar recession and employment  levels
are  not expected to stabilize until late 1994 or 1995. Pre-recession job levels
may not be reached until near the end of the decade. The largest job losses have
been in Southern California, led by  declines in the aerospace and  construction
industries. Weakness statewide occurred in manufacturing, construction, services
and  trade and will be hurt  in the next few years  by continued cuts in federal
defense spending and base closures. Unemployment averaged over 9% in 1993 and is
expected to remain high in  1994. The State's economy  is only expected to  pull
out  of the recession  slowly, following the national  recovery which has begun.
Delay in recovery will exacerbate shortfalls in State revenues.
 
CONSTITUTIONAL LIMITATIONS ON TAXES AND APPROPRIATIONS
 
    LIMITATION  ON  TAXES.  Certain  California  municipal  obligations  may  be
obligations  of issuers which rely in whole  or in part, directly or indirectly,
on AD  VALOREM property  taxes as  a source  of revenue.  The taxing  powers  of
California  local governments and districts are  limited by Article XIIIA of the
California Constitution, enacted  by the voters  in 1978 and  commonly known  as
"Proposition  13." Briefly, Article  XIIIA limits to  1% of full  cash value the
rate of AD VALOREM property taxes  on real property and generally restricts  the
reassessment  of property to 2% per year, except upon new construction or change
of ownership (subject to a number of exemptions). Taxing entities may,  however,
raise  AD VALOREM taxes above the 1% limit to pay debt service on voter-approved
bonded indebtedness.
 
    Under Article XIIIA, the basic 1% AD VALOREM tax levy is applied against the
assessed value of property as of the owner's date of acquisition (or as of March
1, 1975, if acquired earlier), subject  to certain adjustments. This system  has
resulted  in widely  varying amounts  of tax  on similarly  situated properties.
Several lawsuits have  been filed challenging  the acquisition-based  assessment
system of Proposition 13 and on June 18, 1992 the U.S. Supreme Court announced a
decision upholding Proposition 13.
 
    Article  XIIIA prohibits local governments  from raising revenues through AD
VALOREM property  taxes above  the 1%  limit;  it also  requires voters  of  any
governmental  unit to give two-thirds approval  to levy any "special tax." Court
decisions, however, allowed non-voter
 
                                       17
<PAGE>
approved levy of "general taxes" which were not dedicated to a specific use.  In
response  to  these  decisions, the  voters  of  the State  in  1986  adopted an
initiative statute which imposed significant new limits on the ability of  local
entities  to raise  or levy  general taxes,  except by  receiving majority local
voter approval. Significant elements of this initiative, "Proposition 62,"  have
been  overturned in recent  court cases. An initiative  proposed to re-enact the
provisions of Proposition 62 as a  constitutional amendment was defeated by  the
voters in November 1990, but such a proposal may be renewed in the future.
 
    APPROPRIATIONS  LIMITS. California and its  local governments are subject to
an annual  "appropriations limit"  imposed by  Article XIIIB  of the  California
Constitution,  enacted  by  the  voters in  1979  and  significantly  amended by
Propositions 98 and 111 in 1988 and 1990, respectively. Article XIIIB  prohibits
the  State or any covered local government from spending "appropriations subject
to limitation" in  excess of the  appropriations limit imposed.  "Appropriations
subject  to limitation" are  authorizations to spend  "proceeds of taxes," which
consists of  tax  revenues and  certain  other funds,  including  proceeds  from
regulatory  licenses,  user  charges or  other  fees,  to the  extent  that such
proceeds exceed the cost of providing  the product or service, but "proceeds  of
taxes" excludes most State subventions to local governments. No limit is imposed
on appropriations of funds which are not "proceeds of taxes," such as reasonable
user charges or fees, and certain other non-tax funds, including bond proceeds.
 
    Among  the  expenditures not  included in  the Article  XIIIB appropriations
limit are (1)  the debt  service cost  of bonds  issued or  authorized prior  to
January  1, 1979, or  subsequently authorized by  the voters, (2) appropriations
arising from certain  emergencies declared by  the Governor, (3)  appropriations
for  certain  capital  outlay  projects,  (4)  appropriations  by  the  State of
post-1989  increases  in  gasoline  taxes  and  vehicle  weight  fees,  and  (5)
appropriations made in certain cases of emergency.
 
    The  appropriations  limit for  each year  is  adjusted annually  to reflect
changes in  cost  of  living  and  population,  and  any  transfers  of  service
responsibilities  between government units. The definitions for such adjustments
were liberalized in 1990 to follow more closely growth in California's economy.
 
    "Excess" revenues are measured over a two-year cycle. Local governments must
return any excess to taxpayers by rate  reduction. The State must refund 50%  of
any excess, with the other 50% paid to schools and community colleges. With more
liberal  annual adjustment factors since 1988, and depressed revenues since 1990
because of the  recession, few  governments are currently  operating near  their
spending  limits, but this condition may change over time. Local governments may
by voter approval exceed their spending limits for up to four years.
 
    Because of the complex nature of Articles XIIIA and XIIIB of the  California
Constitution,  the ambiguities and possible  inconsistencies in their terms, and
the impossibility of predicting future  appropriations or changes in  population
and  cost of living, and  the probability of continuing  legal challenges, it is
not currently possible to determine fully the impact of Article XIIIA or Article
XIIIB on California  Municipal Obligations or  on the ability  of California  or
local  governments to pay debt service on such California Municipal Obligations.
It is not presently  possible to predict the  outcome of any pending  litigation
with  respect  to  the ultimate  scope,  impact or  constitutionality  of either
Article XIIIA or Article  XIIIB, or the impact  of any such determinations  upon
State  agencies or local governments, or upon  their ability to pay debt service
on  their   obligations.   Future   initiatives  or   legislative   changes   in
 
                                       18
<PAGE>
laws  or the California Constitution may also affect the ability of the State or
local issuers to repay their obligations.
 
    OBLIGATIONS OF THE STATE OF CALIFORNIA. As of April 1, 1994, California  had
approximately  $18.1 billion of  general obligation bonds  outstanding, and $5.6
billion remained authorized  but unissued. In  addition, at June  30, 1993,  the
State  had lease-purchase obligations, payable from the State's General Fund, of
approximately $4.0 billion. Four general obligation bond propositions, totalling
$5.9 billion, will  be on the  June 1994  ballot. In fiscal  year 1992-93,  debt
service  on general obligation  bonds and lease-purchase  debt was approximately
4.1% of General Fund revenues. The State has paid the principal of and  interest
on  its general obligation bonds, lease-purchase debt and short-term obligations
when due.
 
    RECENT FINANCIAL RESULTS. The principal sources of General Fund revenues  in
1992-93  were the  California personal income  tax (44% of  total revenues), the
sales tax (38%), bank and corporation taxes (12%), and the gross premium tax  on
insurance  (3%). California maintains a  Special Fund for Economic Uncertainties
(the "Economic Uncertainties Fund"),  derived from General  Fund revenues, as  a
reserve to meet cash needs of the General Fund.
 
    GENERAL.  Throughout  the 1980's,  State spending  increased rapidly  as the
State population and economy also grew rapidly, including increased spending for
many assistance  programs  to  local  governments,  which  were  constrained  by
Proposition  13 and other laws. The largest State program is assistance to local
public school districts.  In 1988,  an initiative (Proposition  98) was  enacted
which  (subject to suspension  by a two-thirds  vote of the  Legislature and the
Governor) guarantees local  school districts and  community college districts  a
minimum share of State General Fund revenues (currently about 34%).
 
    Since  the  start  of  1990-91  Fiscal Year,  the  State  has  faced adverse
economic, fiscal,  and  budget  conditions.  The  economic  recession  seriously
affected  State tax revenues.  It also caused  increased expenditures for health
and welfare programs.  The State is  also facing a  structural imbalance in  its
budget  with  the largest  programs supported  by  the General  Fund (education,
health, welfare and corrections) growing at  rates higher than the growth  rates
for  the principal revenue sources  of the General Fund.  As a result, the State
entered a period of budget  imbalance, with expenditures exceeding revenues  for
four of the five fiscal years ending in 1991-92.
 
    As  the State fell  into a deep recession  in the summer  of 1990, the State
budget fell sharply  out of  balance in the  1990-91 and  1991-92 fiscal  years,
despite   significant  expenditure  cuts  and   tax  increases.  The  State  had
accumulated a $2.8 billion  budget deficit by June  30, 1992. This deficit  also
severely  reduced the State's cash resources, so that it had to rely on external
borrowing in the short-term markets to meet its cash needs.
 
    1992-93 FISCAL YEAR.  With  the failure to enact a  budget by July 1,  1992,
the State had no legal authority to pay many of its vendors until the budget was
passed;   nevertheless,  certain  obligations  (such  as  debt  service,  school
apportionments, welfare payments, and employee salaries) were payable because of
continuing or  special  appropriations,  or court  orders.  However,  the  State
Controller did not have enough cash to pay as they came due all of these ongoing
obligations, as well as valid obligations incurred in the prior fiscal year.
 
    Because  of the delay in enacting the  budget, the State could not carry out
its normal cash flow borrowing and, starting on July 1, 1992, the Controller was
required to issue  "registered warrants" in  lieu of normal  warrants backed  by
cash   to  pay  many   State  obligations.  Available  cash   was  used  to  pay
constitutionally mandated and priority obligations.
 
                                       19
<PAGE>
Between July 1  and September  3, 1992, the  Controller issued  an aggregate  of
approximately  $3.8 billion of registered warrants, all of which were called for
redemption by September 4,  1992 following enactment of  the 1992-93 Budget  Act
and issuance by the State of $3.3 billion of Interim Notes.
 
    The 1992-93 Budget Act, when finally adopted, was projected to eliminate the
State's accumulated deficit, with additional expenditure cuts and a $1.3 billion
transfer of State education funding costs to local governments by shifting local
property  taxes to school districts. However,  as the recession continued longer
and deeper than expected,  revenues once again were  far below projections,  and
only  reached a level just equal to  the amount of expenditures. Thus, the State
continued to carry its $2.8 billion budget deficit at June 30, 1993.
 
    The 1993-94  Budget  Act was  similar  to the  prior  year, in  reliance  on
expenditure  cuts  and an  additional $2.6  billion transfer  of costs  to local
government, particularly counties. A major feature of the budget was a  two-year
plan  to eliminate the accumulated deficit  by borrowing into the 1994-95 fiscal
year. With  the recession  still continuing  longer than  expected, the  1994-95
Governor's Budget now projects that in the 1993-94 Fiscal Year, the General Fund
will  have $900 million  less revenue and $800  million higher expenditures than
budgeted. As  a result  revenues will  only exceed  expenditures by  about  $400
million.  If this projection is  met, it will be  the first operating surplus in
four years;  however, some  budget analysts  outside the  Department of  Finance
project revenues in the balance of 1993-94 will not even meet the revised, lower
projection.  In addition,  the General  Fund may  have some  unplanned costs for
relief related to the January 17, 1994 Northridge earthquake.
 
    The State has implemented  its short-term borrowing as  part of the  deficit
elimination  plan,  and has  also borrowed  additional sums  to cover  cash flow
shortfalls in the spring  of 1994, for  a total of $3.2  billion, coming due  in
July  and  December,  1994. Repayment  of  these short-term  notes  will require
additional borrowing, as  the State's  cash position continues  to be  adversely
affected.
 
    The  Governor's 1994-95 Budget proposal recognizes  the need to bridge a gap
of around $5 billion by June 30, 1995. Over $3.1 billion of this amount is being
requested from the federal government  as increased aid, particularly for  costs
associated  with  incarcerating,  educating  and  providing  health  and welfare
services to undocumented immigrants. However, President Clinton has not included
these costs in his proposed  Fiscal 1995 Budget. The rest  of the budget gap  is
proposed  to be closed with  expenditure cuts and projected  $600 million of new
revenue assuming the State wins a tax case presently pending in the U.S. Supreme
Court. Thus the State  will once again face  significant uncertainties and  very
difficult  choices in the 1994-95 budget, as tax increases are unlikely and many
cuts and budget adjustments have been made in the past three years.
 
    The State's  severe  financial difficulties  for  the current  and  upcoming
budget   years  will  result  in  continued   pressure  upon  almost  all  local
governments, particularly school  districts and counties  which depend on  State
aid.  Despite efforts in recent years  to increase taxes and reduce governmental
expenditures, there can be no assurance that the State will not face budget gaps
in the future.
 
    BOND RATING.    State general obligation bonds  are currently rated "Aa"  by
Moody's  and "A+" by S&P.  Both of these ratings  were reduced from "AAA" levels
which the  State held  until late  1991. There  can be  no assurance  that  such
ratings  will  be  maintained  in  the  future.  It  should  be  noted  that the
creditworthiness   of   obligations   issued   by   local   California   issuers
 
                                       20
<PAGE>
may  be unrelated to the creditworthiness of  obligations issued by the State of
California, and that there  is no obligation  on the part of  the State to  make
payment on such local obligations in the event of default.
 
    LEGAL  PROCEEDINGS.   The  State is  involved  in certain  legal proceedings
(described in the State's recent financial statements) that, if decided  against
the  State, may require the State to make significant future expenditures or may
substantially impair revenues. The U.S. Supreme Court has granted review of  two
cases   challenging  California's  "unitary"   method  of  taxing  multinational
corporations. Although this taxing method has  since been changed, if the  State
loses these cases, it could be liable for tax refunds and lost receipts of taxes
assessed totalling $3.5 billion to $4 billion.
 
OBLIGATIONS OF OTHER ISSUERS
 
    OTHER  ISSUERS OF  CALIFORNIA MUNICIPAL OBLIGATIONS.  There are  a number of
state agencies, instrumentalities and political  subdivisions of the State  that
issue  Municipal Obligations, some  of which may  be conduit revenue obligations
payable from  payments from  private borrowers.  These entities  are subject  to
various  economic  risks  and  uncertainties,  and  the  credit  quality  of the
securities issued by them may vary  considerably from the credit quality of  the
obligations backed by the full faith and credit of the State.
 
    STATE  ASSISTANCE.  Property  tax  revenues  received  by  local governments
declined more than 50%  following passage of  Proposition 13. Subsequently,  the
California Legislature enacted measures to provide for the redistribution of the
State's  General Fund  surplus to  local agencies,  the reallocation  of certain
State revenues  to local  agencies and  the assumption  of certain  governmental
functions  by the  State to  assist municipal  issuers to  raise revenues. Total
local assistance (including public schools)  accounted for approximately 75%  of
General  Fund expenditures, including  the effect of  implementing reductions in
certain aid programs. To reduce State General Fund support for school districts,
the 1992-93 and 1993-94  Budget Acts caused local  governments to transfer  $3.9
billion  of property tax revenues to  school districts, representing loss of all
of the post-Proposition 13 "bailout" aid.  The largest share of these  transfers
came  from  counties,  and  the  balance  from  cities,  special  districts  and
redevelopment agencies.  In order  to make  up this  shortfall, the  Legislature
proposed  and voters approved dedicating  0.5% of the sales  tax to counties and
cities for public safety purposes. In addition, the Legislature has changed laws
to relieve local governments of certain mandates, allowing them to reduce costs.
 
    To the  extent  the  State  should  be  constrained  by  its  Article  XIIIB
appropriations  limit, or its obligation to  conform to Proposition 98, or other
fiscal considerations,  the absolute  level, or  the rate  of growth,  of  State
assistance to local governments may be reduced. Any such reductions in State aid
could  compound the serious fiscal constraints already experienced by many local
governments, particularly counties. The Richmond Unified School District (Contra
Costa County) entered  bankruptcy proceedings  in May 1991  but the  proceedings
have been dismissed.
 
    ASSESSMENT  BONDS.  California  Municipal Obligations  which  are assessment
bonds may be adversely affected by a general decline in real estate values or  a
slowdown in real estate sales activity. In many cases, such bonds are secured by
land  which  is  undeveloped at  the  time  of issuance  but  anticipated  to be
developed within a few years after issuance.  In the event of such reduction  or
slowdown,  such development may not occur  or may be delayed, thereby increasing
the risk of a  default on the  bonds. Because the  special assessments or  taxes
securing  these  bonds are  not  the personal  liability  of the  owners  of the
property
 
                                       21
<PAGE>
assessed, the lien on the property is the only security for the bonds. Moreover,
in most cases the issuer of these bonds is not required to make payments on  the
bonds in the event of delinquency in the payment of assessments or taxes, except
from amounts, if any, in a reserve fund established for the bonds.
 
    CALIFORNIA  LONG-TERM LEASE OBLIGATIONS.  Certain California long-term lease
obligations, though typically payable from the general fund of the municipality,
are subject to "abatement" in the event the facility being leased is unavailable
for beneficial use  and occupancy  by the municipality  during the  term of  the
lease. Abatement is not a default, and there may be no remedies available to the
holders  of  the  certificates  evidencing the  lease  obligation  in  the event
abatement occurs. The  most common cases  of abatement are  failure to  complete
construction  of the facility  before the end  of the period  during which lease
payments have been  capitalized and  uninsured casualty losses  to the  facility
(E.G., due to earthquake). In the event abatement occurs with respect to a lease
obligation,  lease  payments  may  be interrupted  (if  all  available insurance
proceeds and reserves are exhausted) and  the certificates may not be paid  when
due.
 
    Several  years  ago the  Richmond Unified  School District  (the "District")
entered into a  lease transaction in  which certain existing  properties of  the
District  were sold and leased back in  order to obtain funds to cover operating
deficits. Following a fiscal crisis in which the District's finances were  taken
over  by  a State  receiver  (including a  brief  period under  bankruptcy court
protection), the  District  failed  to  make  rental  payments  on  this  lease,
resulting  in  a lawsuit  by the  Trustee for  the Certificate  of Participation
holders, in  which the  State was  a named  defendant (on  the grounds  that  it
controlled  the District's  finances). One of  the defenses raised  in answer to
this lawsuit was  the invalidity of  the District's lease.  The trial court  has
upheld  the validity of the lease and the case has been settled. Any judgment in
a future case against the position asserted by the Trustee in the Richmond  case
may  have adverse  implications for  lease transactions  of a  similar nature by
other California entities.
 
    OTHER CONSIDERATIONS.  The repayment  of industrial  development  securities
secured by real property may be affected by California laws limiting foreclosure
rights  of creditors. Securities backed by health care and hospital revenues may
be affected by  changes in  State regulations governing  cost reimbursements  to
health  care providers under Medi-Cal  (the State's Medicaid program), including
risks  related  to  the  policy  of  awarding  exclusive  contracts  to  certain
hospitals.
 
    Limitations  on  AD  VALOREM  property taxes  may  particularly  affect "tax
allocation" bonds issued  by California redevelopment  agencies. Such bonds  are
secured  solely by the increase in assessed valuation of a redevelopment project
area after  the start  of redevelopment  activity. In  the event  that  assessed
values  in the redevelopment  project decline (E.G., because  of a major natural
disaster such as an earthquake), the  tax increment revenue may be  insufficient
to  make principal and  interest payments on  these bonds. Both  Moody's and S&P
suspended ratings  on California  tax allocation  bonds after  the enactment  of
Articles XIIIA and XIIIB, and only resumed such ratings on a selective basis.
 
    Proposition  87, approved  by California voters  in 1988,  requires that all
revenues produced by a tax rate increase go directly to the taxing entity  which
increased  such tax rate to repay that entity's general obligation indebtedness.
As a result, redevelopment  agencies (which, typically, are  the issuers of  tax
allocation securities) no longer receive an increase in tax increment when taxes
on  property in  the project area  are increased to  repay voter-approved bonded
indebtedness.
 
                                       22
<PAGE>
    The effect of these  various constitutional and  statutory changes upon  the
ability of California municipal securities issuers to pay interest and principal
on  their obligations remains unclear. Furthermore, other measures affecting the
taxing or spending authority of California or its political subdivisions may  be
approved  or enacted in  the future. Legislation  has been or  may be introduced
which would modify  existing taxes  or other revenue-raising  measures or  which
either  would further limit  or, alternatively, would  increase the abilities of
state and local governments to impose  new taxes or increase existing taxes.  It
is  not presently possible to  predict the extent to  which any such legislation
will be enacted. Nor  is it presently  possible to determine  the impact of  any
such  legislation  on California  Municipal Obligations  in  which the  Fund may
invest, future  allocations  of  state  revenues to  local  governments  or  the
abilities  of state or  local governments to  pay the interest  on, or repay the
principal of, such California Municipal Obligations.
 
    Substantially all of California is within an active geologic region  subject
to major seismic activity. Any California Municipal Obligation in the California
Insured  Trust  could be  affected  by an  interruption  of revenues  because of
damaged facilities, or, consequently, income tax deductions for casualty  losses
or  property tax assessment reductions.  Compensatory financial assistance could
be constrained by  the inability of  (i) an issuer  to have obtained  earthquake
insurance  coverage  at reasonable  rates;  (ii) an  insurer  to perform  on its
contracts of insurance in the event  of widespread losses; or (iii) the  Federal
or  State  government to  appropriate sufficient  funds within  their respective
budget limitations.
 
    On January 17, 1994, a major  earthquake with an estimated magnitude of  6.8
on  the Richter scale struck the  Los Angeles area, causing significant property
damage to public and private facilities, presently estimated at $15-20  billion.
While  over $9.5 billion of  federal aid, and a  projected $1.9 billion of State
aid, plus insurance proceeds,  will reimburse much of  that loss, there will  be
some  ultimate loss of wealth and income in  the region, in addition to costs of
the  disruption  caused  by  the  event.  Short-term  economic  projections  are
generally  neutral, as the infusion  of aid will restore  billions of dollars to
the local economy within a few  months; already the local construction  industry
has  picked up. Although the earthquake  will hinder recovery from the recession
in Southern California, already hard-hit,  its long-term impact is not  expected
to  be material in the context of the  overall wealth of the region. Almost five
years after the event, there are few  remaining effects of the 1989 Loma  Prieta
earthquake  in northern  California (which,  however, caused  less severe damage
than Northridge).

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

    *  The State tax rates assumed take into account the adjustment  of tax brackets based on changes in the Consumer Price Index
for 1994.
      1 The table reflects the effect of the limitations  on itemized deductions and the deduction for personal exemptions.  They
were  designed to phase out certain benefits of these deductions for higher income taxpayers. These limitations, in effect, raise
the current maximum marginal Federal tax rate to approximately 44.0  percent for taxpayers filing a joint return and entitled  to
four  personal exemptions and to  approximately 41.0 percent for taxpayers  filing a single return  entitled to only one personal
exemption. These limitations are  subject to certain maximums,  which depend on  the number of exemptions  claimed and the  total
amount  of the taxpayer's itemized  deductions. For example, the limitation  on itemized deductions will  not cause a taxpayer to
lose more than 80% of his allowable itemized deductions,  with certain exceptions. The table also reflects California income  tax
laws  that increase state income tax rates for high income taxpayers,  limit itemized deductions and phase out the benefit of the
personal exemption credit and the dependent exemption credit in a manner similar to Federal tax law.
      2 Federal tax rate reverts to 36.0% and the state tax rate reverts to the applicable stated maximum rate after the 80%  cap
on the limitation on itemized deductions, under federal or state law, as appropriate has been met.
      3 Federal tax rate reverts to 39.6% after the 80% cap on the limitation on itemized deductions has been met.
</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.

FLORIDA INSURED TRUST 202
    
   
    The  Portfolio of Florida Insured Trust 202 consists of 6 obligations issued
by entities located in Florida and one obligation issued by an entity located in
the Territory of Puerto Rico. Two Bonds in the Trust are general obligations  of
the  governmental  entities issuing  them and  are backed  by the  taxing powers
thereof. Five Bonds in the Trust are  payable as to principal and interest  from
the  income of  a specific  project or  authority and  are not  supported by the
issuer's power to levy taxes. The sources of payment for these Bonds are divided
as follows: Electrical System Revenue, 3;  Health Care Facility Revenue, 2.  All
of  the Bonds  in the  Trust, as  insured, are  rated AAA  by Standard  & Poor's
Corporation and Aaa by Moody's Investors Service, Inc.
    
 
   
    At the Date of  Deposit, the average  maturity of the  Bonds in the  Florida
Insured  Trust is 29.7  years. The average maturity  of the Bonds  in a Trust is
calculated based upon the stated maturities of the Bonds in such Trust (or, with
respect to Bonds for  which funds or  securities have been  placed in escrow  to
redeem such Bonds on a stated call date, based upon such call date). The average
maturity  of the Bonds in a Trust may  increase or decrease from time to time as
Bonds mature or are called or sold.
    
 
    Approximately 43% 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.
 
    Approximately 29% of  the aggregate  principal amount  of the  Bonds in  the
Trust  consists of obligations  of issuers whose  revenues are primarily derived
from services provided by hospitals or other health care facilities.
 
    For a discussion of  the risks associated with  investments in the bonds  of
various issuers, see "General Trust Information" in this section.
 
   
    The Sponsor entered into contracts to acquire the Bonds on December 6, 1994.
The  following summarizes certain information about the Bonds as of the business
day prior to the Date of Deposit:

</TABLE>
 
    Neither  cost  to  Sponsor  nor   profit  (or  loss)  to  Sponsor   reflects
underwriting  profits or losses received or  incurred by the Sponsor through its
participation  in  underwriting  syndicates.  An  underwriter  or   underwriting
syndicate  purchases bonds  from the issuer  on a negotiated  or competitive bid
basis as principal with  the motive of  marketing such bonds  to investors at  a
profit.  The Sponsor did not participate as  either the sole underwriter or as a
manager or member of a syndicate that  acted as the original underwriter of  any
of the Bonds.
 
   
    Unitholders  may elect  to have  interest distributions  made on  a monthly,
quarterly or semi-annual basis. The interest on the Bonds initially deposited in
the Florida Insured Trust,  less estimated expenses, is  estimated to accrue  at
the rate of $.01534 per Unit per day under the semi-annual plan of distribution,
$.01529  per Unit per day  under the quarterly plan  of distribution and $.01520
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 Florida  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

mature or are sold or as fees and expenses increase or decrease.
 
TAX STATUS--FLORIDA INSURED TRUST
 
    For  a discussion  of the  Federal tax  status of  income earned  on Florida
Insured Trust Units, see Section 11.
 
    The assets of the Florida Insured Trust (the "Trust") will consist solely of
interest-bearing obligations issued by or on behalf of the State of Florida, its
political subdivisions and authorities  or by the  Commonwealth of Puerto  Rico,
Guam,  the Virgin Islands, American Samoa,  or the Northern Mariana Islands (the
"Florida Bonds").
 
    In the opinion  of Carlton, Fields,  Ward, Emmanuel, Smith  & Cutler,  P.A.,
special counsel for the Trust for Florida tax matters, under existing law:
 
        For  Florida state income tax purposes, the Trust will not be subject to
    the Florida income tax imposed by the Florida Code so long as the Trust  has
    no  income subject to federal  taxation. In addition, political subdivisions
    of Florida do not impose any income taxes.
 
        Because  Florida  does  not  impose   an  income  tax  on   individuals,
    non-corporate  Unitholders will not be subject  to any Florida income tax on
    income realized by the Trust. Each  corporate Unitholder will be subject  to
    Florida  income taxation on  its share of  the income realized  by the Trust
    notwithstanding the  tax exempt  status of  the interest  received from  any
    bonds under Section 103(a) of the Internal Revenue Code of 1986 or any other
    federal  law,  unless the  interest  income constitutes  nonbusiness income.
    Nevertheless, any corporate Unitholder that  has its commercial domicile  in
    Florida  will be taxable  under the Florida  Code on its  share of the Trust
    income which constitutes nonbusiness income.
 
        Trust Units  will be  subject to  Florida estate  tax only  if owned  by
    Florida  residents,  certain natural  persons not  domiciled in  Florida, or
    certain natural persons  not residents  of the United  States. However,  the
    Florida  estate tax is limited  to the amount of  the credit allowable under
    the applicable  Federal Revenue  Act (currently  Section 2011  (and in  some
    cases  Section 2102) of the  Internal Revenue Code of  1986, as amended) for
    death taxes actually paid to the several states.
 
        Neither the Florida Bonds nor the  Units will be subject to the  Florida
    ad valorem property tax or Florida sales or use tax.
 
        Because   Bonds  issued  by  the  State  of  Florida  or  its  political
    subdivisions or  by  the  Commonwealth  of Puerto  Rico,  Guam,  the  Virgin

    Northern  Mariana  Islands  are  exempt  from  Florida  intangible  personal
    property taxation under Chapter 199, Florida Statutes, as amended, the Trust
    will not  be  subject  to  Florida  intangible  personal  property  tax.  In
    addition, the Unitholders will not be subject to Florida intangible personal
    property tax on the Units.
 
ECONOMIC FACTORS--FLORIDA
 
    POPULATION.   In 1980,  Florida was the  seventh most populous  state in the
U.S. The State has grown dramatically since then and as of April 1, 1993,  ranks
fourth  with an estimated  population of 13.4  million. Florida's attraction, as
both a growth and retirement state, has kept net migration fairly steady with an
average of 292,988 new residents a year from 1983 through 1993. The U.S. average
population increase since  1982 is  about 1% annually,  while Florida's  average
annual  rate of  increase is  about 2.5%.  Florida continues  to be  the fastest
growing of the ten largest states.  This strong population growth is one  reason
the State's economy is performing better than the nation as a whole. In addition
to attracting senior citizens to Florida as a place for retirement, the State is
also  recognized as attracting a significant  number of working age individuals.
Since 1983, the  prime working age  population (18-44) has  grown at an  average
annual rate of 2.6%. The share of Florida's total working age population (18-59)
to  total State population is  approximately 54%. This share  is not expected to
change appreciably into the twenty-first century.
 
    INCOME.  The  State's personal  income has  been growing  strongly the  last
several  years and has generally  outperformed both the U.S.  as a whole and the
southeast in particular, according  to the U.S. Department  of Commerce and  the
Florida  Consensus Economic Estimating Conference. This  is due to the fact that
Florida's population has been growing at a very strong pace and, since the early
1970's, the State's economy has diversified so as to provide greater  insulation
from  national  economic  downturns.  As a  result,  Florida's  real  per capita
personal income has tracked  closely with the national  average and has  tracked
above  the southeast. From 1984 through 1993, the State's real per capita income
rose at an average of 5.4% per  year, while the national real per capita  income
increased at an average of 5.5% per year.
 
    Because  Florida has  a proportionately  greater retirement  age population,
property income (dividends,  interest, and rent)  and transfer payments  (Social
Security  and pension  benefits, among other  sources of  income) are relatively
more important  sources  of  income.  For example,  Florida's  total  wages  and
salaries  and other labor income in 1993 was 62% of total personal income, while
a similar  figure  for  the nation  for  1990  was 72%.  Transfer  payments  are
typically  less  sensitive to  the business  cycle  than employment  income and,
therefore, act as stabilizing forces in weak economic periods.
 
    The State's per capita personal income in 1992 of $19,711 was slightly below
the national  average  of  $20,105  and significantly  ahead  of  that  for  the
southeast United States, which was $17,296. Real personal income in the State is
estimated  to  increase 5.5%  in  1993-94 and  4.7% in  1994-95.  By the  end of
1994-95, real personal income  per capita in the  State is projected to  average
6.7% higher than its 1992-93 level.
 
    EMPLOYMENT.   Since 1980, the State's job  creation rate is almost twice the
rate for the nation as a whole, and its growth rate in new non-agricultural jobs
is the fastest of the 11 most populous states, second only to California in  the
absolute  number of new jobs created. Contributing  to the State's rapid rate of
growth in employment and income is international trade. Since 1980, the  State's
unemployment  rate has generally  been below that  of the U.S.  In recent years,
however, as the State's economic growth has slowed from its previous highs,  the
State's  unemployment rate has  tracked above the  national average. The average
rate in Florida since  1980 has been  6.5% while the  national average is  7.1%.
According  to the U.S.  Department of Commerce, the  Florida Department of Labor
and  Employment  Security,  and   the  Florida  Consensus  Economic   Estimating
Conference (together, the "Organization"), the
 
                                       29
<PAGE>
State's  unemployment  rate  was  8.2%  during 1992.  As  of  January  1994, the
Organization estimates that the unemployment rate  will be 6.7% for 1993-94  and
6.1% in 1994-95.
 
    The rate of job creation in Florida's manufacturing sector has exceeded that
of the U.S. From the beginning of 1980 through 1993, the State added over 50,000
new  manufacturing jobs,  an 11.7%  increase. During  the same  period, national
manufacturing employment declined ten out of  the fourteen years, for a loss  of
2,977,000 jobs.
 
    Total non-farm employment in Florida is expected to increase 2.7% in 1993-94
and  rise  3.8% in  1994-95.  Trade and  services,  the two  largest  sources of
employment in  the State,  account for  more  than half  of the  total  non-farm
employment.  Employment in the service sector's should experience an increase of
3.9% in 1993-94, while growing 4.9% in 1994-95. Trade is expected to expand 2.2%
in 1994  and  3.4% in  1995.  The service  sector  is now  the  State's  largest
employment category.
 
    CONSTRUCTION.   The State's economy has in the past been highly dependent on
the  construction  industry   and  construction   related  manufacturing.   This
dependency  has declined in recent  years and continues to do  so as a result of
continued diversification of the  State's economy. For  example, in 1980,  total
contract  construction employment  as a share  of total  non-farm employment was
just over 7.0%, and in 1993 the share had edged downward to 5.0%. This trend  is
expected  to continue  as the State's  economy continues  to diversify. Florida,
nevertheless, has a dynamic construction industry, with single and  multi-family
housing  starts accounting for 8.5%  of total U.S. housing  starts in 1993 while
the State's population is 5.3% of  the U.S. total population. Florida's  housing
starts  since 1980  have represented  an average  of 11.0%  of the  U.S.'s total
annual starts, and  since 1980,  total housing  starts have  averaged 156,450  a
year.
 
    A  driving  force  behind the  State's  construction industry  has  been the
State's rapid rate  of population growth.  Although the State  currently is  the
fourth  most populous  state, its annual  population growth is  now projected to
decline as the number of people moving into the State is expected to hover  near
the  mid 250,000  range annually  throughout the  1990's. This  population trend
should  provide  plenty  of  fuel  for  business  and  home  builders  to   keep
construction  activity lively in  Florida for some time  to come. However, other
factors do  influence the  level  of construction  in  the State.  For  example,
federal tax reform in 1986 and other changes to the federal income tax code have
eliminated  tax deductions for  owners of more than  two residential real estate
properties  and  have  lengthened  depreciation  schedules  on  investment   and
commercial  properties.  Economic growth  and  existing supplies  of  homes also
contribute to the level of construction activity in the State.
 
    Hurricane Andrew left some parts of south Florida devastated. Post-Hurricane
Andrew clean up and rebuilding have changed the outlook for the State's economy.
Single and  multi-family housing  starts in  1993-94 are  projected to  reach  a
combined  level  of 118,000,  and to  increase to  134,300 next  year. Lingering
recessionary effects on consumers and tight  credit are some of the reasons  for
relatively  slow core construction  activity, as well  as lingering effects from
the 1986 tax reform legislation discussed above. However, construction is one of
the sectors most severely affected by  Hurricane Andrew. Low interest rates  and
pent  up  demand  combined  with improved  consumer  confidence  should  lead to
improved housing  starts.  The  construction figures  above  include  additional
housing   starts  as  a  result  of   destruction  by  Hurricane  Andrew.  Total
construction expenditures  are  forecasted  to  increase  15.6%  this  year  and
increase 13.3% next year.
 
    The   State  has  continuously   been  dependent  on   the  highly  cyclical
construction and  construction  related  manufacturing  industries.  While  that
dependency  has  decreased, the  State is  still  somewhat at  the mercy  of the
construction and construction related manufacturing industries. The construction
industry is driven to a great extent by the State's rapid growth in  population.
There   can   be   no   assurance   that   population   growth   will   continue
 
                                       30
<PAGE>
throughout the 1990's  in which case  there could  be an adverse  impact on  the
State's  economy  through  the  loss of  construction  and  construction related
manufacturing jobs. Also, while interest rates remain low currently, an increase
in interest  rates could  significantly adversely  impact the  financing of  new
construction  within  the State,  thereby  adversely impacting  unemployment and
other economic  factors  within the  State.  In addition,  available  commercial
office  space has tended to remain high over the past few years. So long as this
glut of commercial rental  space continues, construction of  this type of  space
will likely continue to remain slow.
 
    TOURISM.    Tourism  is  one  of  the  State's  most  important  industries.
Approximately 41.1 million tourists  visited the State in  1993, as reported  by
the  Florida Department of  Commerce. In terms of  business activities and state
tax revenues, tourists in Florida in  1993 represented an estimated 4.5  million
additional  residents. Visitors to the  State tend to arrive  equally by air and
car. The State's tourism industry over the years has become more  sophisticated,
attracting  visitors year-round and, to a  degree, reducing its seasonality. The
dollar's  depreciation  has  enhanced  the  State's  tourism  industry.  Tourist
arrivals  are  expected to  decline by  almost  two percent  this year,  but are
expected to recover next year with  5.0% growth. Tourist arrivals to Florida  by
air  and car are  expected to diverge  from each other,  air decreasing 5.6% and
auto increasing  1.6%. By  the end  of  the State's  current fiscal  year,  41.0
million  domestic and  international tourists are  expected to  have visited the
State. In 1994-95 tourist arrivals should approximate 43.0 million.
 
    REVENUES AND EXPENSES.  Estimated  fiscal year 1993-94 General Revenue  plus
Working  Capital funds available  to the State total  $13,582.7 million, an 8.4%
increase over  1992-93. This  reflects a  transfer of  $190 million,  out of  an
estimated  $220.0 million in non-recurring revenue due to Hurricane Andrew, to a
hurricane relief trust fund. Of the  total General Revenue plus Working  Capital
funds  available to the  State, $12,943.5 million of  that is Estimated Revenues
(excluding the Hurricane Andrew  impact), which represents  an increase of  7.3%
over  the previous  year's Estimated  Revenues. With  effective General Revenues
plus Working  Capital Fund  appropriations  at $13,276.9  million,  unencumbered
reserves at the end of 1993-94 are estimated at $302.8 million. Estimated fiscal
year 1994-95 General Revenue plus Working Capital and Budget Stabilization funds
available  total $14,573.7  million, a 7.3%  increase over  1993-94. This amount
reflects a transfer of $159.0 million in non-recurring revenue due to  Hurricane
Andrew  to a hurricane relief fund.  The $13,860.8 million in Estimated Revenues
(excluding Hurricane  Andrew impact)  represent  an increase  of 7.1%  over  the
previous  year's Estimated Revenues.  The massive effort  to rebuild and replace
destroyed or damaged property in the wake of Hurricane Andrew is responsible for
the substantial positive revenue  impacts shown here. Most  of the impact is  in
the increase in the State's sales tax.
 
    In  fiscal  year  1992-93, approximately  62%  of the  State's  total direct
revenue to its three operating funds was derived from State taxes, with  Federal
grants and other special revenue accounting for the balance. State sales and use
tax,  corporate income  tax, intangible personal  property tax  and beverage tax
amounted to 68%,  7%, 4% and  4%, respectively, of  total General Revenue  Funds
available  during fiscal 1992-93. In that same year, expenditures for education,
health and welfare, and  public safety amounted to  approximately 49%, 30%,  and
11%, respectively, of total expenditures from the General Revenue Fund.
 
    The State's sales and use tax (6%) currently accounts for the State's single
largest  source of tax receipts. Sightly less  than 10% of the State's sales and
use tax is designated for local governments and is distributed to the respective
counties in which  collected for  use by  the counties,  and the  municipalities
therein.  In addition  to this  distribution, local  governments may  assess (by
referendum) a 0.5%  or a 1.0%  discretionary sales surtax  within their  county.
Proceeds  from  this local  option  sales tax  are  earmarked for  funding local
infrastructure programs and acquiring land for public recreation or conservation
or protection of
 
                                       31
<PAGE>
natural resources  as provided  under applicable  Florida law.  Certain  charter
counties have other additional taxing powers, and non-consolidated counties with
a  population in  excess of 800,000  may levy a  local option sales  tax to fund
indigent health care.  It alone cannot  exceed 0.5% and  when combined with  the
infrastructure  surtax cannot  exceed 1.0%. For  the fiscal year  ended June 30,
1993, sales and use tax receipts (exclusive  of the tax on gasoline and  special
fuels) totalled $9,426.0 million, an increase of 12.5% over fiscal year 1991-92.
 
    The  second largest source of State tax  receipts is the tax on motor fuels.
However, these revenues are almost  entirely dedicated trust funds for  specific
purposes and are not included in the State's General Revenue Fund.
 
    The  State imposes an alcoholic beverage wholesale tax (excise tax) on beer,
wine, and  liquor. This  tax  is one  of the  State's  major tax  sources,  with
revenues totalling $442.2 million in fiscal year ending June 30, 1993. Alcoholic
beverage  tax  receipts  increased  1.6% from  the  previous  year's  total. The
revenues collected from this tax are deposited into the State's General  Revenue
Fund.
 
    The  State imposes  a corporate  income tax.  All receipts  of the corporate
income tax are credited to the General  Revenue Fund. For the fiscal year  ended
June  30, 1993, receipts  from this source  were $846.6 million,  an increase of
5.6% from fiscal year 1991-92.
 
    The State  imposes a  documentary stamp  tax on  deeds and  other  documents
relating  to  realty,  corporate shares,  bonds,  certificates  of indebtedness,
promissory notes, wage assignments, and retail charge accounts. The  documentary
stamp  tax collections  totalled $639.0  million during  fiscal year  1992-93, a
27.0% increase from the previous fiscal year. Beginning in fiscal year  1992-93,
71.29% of these taxes is to be deposited to the General Revenue Fund.
 
    The  State  imposes  a gross  receipts  tax  on electric,  natural  gas, and
telecommunications services.  All gross  receipt utilities  tax collections  are
credited  to the State's Public Education  Capital Outlay and Debt Service Trust
Fund. In fiscal year 1992-93, this amounted to $447.9 million.
 
    The State  imposes an  intangible personal  property tax  on stocks,  bonds,
including  bonds secured by liens in  Florida real property, notes, governmental
leaseholds, and certain other intangibles not secured by a lien on Florida  real
property.  The  annual  rate  of  tax  is  2  mils.  The  State  also  imposes a
non-recurring 2 mil tax on mortgages  and other obligations secured by liens  on
Florida  real  property.  In  fiscal  year  1992-93,  total  intangible personal
property tax collections  were $783.4  million, a  33% increase  over the  prior
year. Of the tax proceeds, 66.5% is distributed to the General Revenue Fund.
 
    The  State's severance tax taxes oil, gas and sulphur production, as well as
the severance of phosphate rock and other solid minerals. Total collections from
severance taxes total $64.5 million during  fiscal year 1992-93, down 4.0%  from
the  previous year. Currently 60%  of this amount is  transferred to the General
Revenue Fund.
 
    The State began  its own lottery  in 1988. State  law requires that  lottery
revenues  be  distributed  50.0% to  the  public  in prizes,  38.0%  for  use in
enhancing education,  and the  balance, 12.0%,  for costs  of administering  the
lottery.  Fiscal  year  1992-93  lottery ticket  sales  totalled  $2.13 billion,
providing education with approximately $810.4 million.
 
    DEBT-BALANCED BUDGET REQUIREMENT.  At the end of fiscal 1993,  approximately
$5.61  billion in principal amount of debt  secured by the full faith and credit
of the State was outstanding. In addition, since July 1, 1993, the State  issued
about $1.13 billion in principal amount of full faith and credit bonds.
 
    The  State Constitution  and statutes  mandate that  the State  budget, as a
whole, and each separate fund within the  State budget, be kept in balance  from
currently  available revenues each  fiscal year. If  the Governor or Comptroller
believe a deficit will occur in any State fund, by statute, he must certify  his
opinion to the Administrative Commission, which then is
 
                                       32
<PAGE>
authorized  to  reduce all  State agency  budgets and  releases by  a sufficient
amount to prevent a  deficit in any fund.  Additionally, the State  Constitution
prohibits issuance of State obligations to fund State operations.
 
    LITIGATION.  Currently under litigation are several issues relating to State
actions  or State taxes that put at  risk substantial amounts of General Revenue
Fund monies.  Accordingly, there  is  no assurance  that  any of  such  matters,
individually or in the aggregate, will not have a material adverse affect on the
State's financial position.
 
    Florida  law provides preferential tax treatment  to insurers who maintain a
home office in the State.  Certain insurers challenged the constitutionality  of
this  tax preference and  sought a refund  of taxes paid.  Recently, the Florida
Supreme Court ruled  in favor of  the State.  This case and  others, along  with
pending refund claims, total about $150 million.
 
    The  State imposes a $295  fee on the issuance  of certificates of title for
motor vehicles previously titled outside the  State. The State has been sued  by
plaintiffs  alleging  that this  fee violates  the Commerce  Clause of  the U.S.
Constitution. The Circuit Court in which the case was filed has granted  summary
judgment  for the plaintiffs  and has enjoined further  collection of the impact
fee and  has ordered  refunds to  all  those who  have paid  the fee  since  the
collection of the fee went into effect. The State has appealed the lower Court's
decision  and an  automatic stay has  been granted  to the State  allowing it to
continue to collect the fee.  The potential refund exposure  to the State if  it
should lose the case may be in excess of $100 million.
 
    The  State  maintains a  bond rating  of  Aa and  AA from  Moody's Investors
Service and Standard & Poor's Corporation, respectively, on the majority of  its
general  obligation bonds, although the rating of a particular series of revenue
bonds relates primarily to the project,  facility, or other revenue source  from
which  such series derives funds for repayment.  While these ratings and some of
the information  presented above  indicate  that the  State is  in  satisfactory
economic  health, there can be no assurance that  there will not be a decline in
economic conditions or that particular Florida Bonds purchased by the fund  will
not be adversely affected by any such changes.
 
    The  sources for the information presented above include official statements
and financial statements  of the  State of Florida.  While the  Sponsor has  not
independently  verified this information,  it has no reason  to believe that the
information is not correct in all material respects.
 
FLORIDA TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The following tables show the approximate taxable estimated current  returns
for  individuals  that are  equivalent to  tax-exempt estimated  current returns
under  published  1994  marginal  Federal  tax  rates.  The  tables  incorporate
increased  tax  rates  for higher-income  taxpayers  that were  included  in the
Revenue Reconciliation Act of 1993. The tables illustrate what you would have to
earn on taxable investments to equal the tax-exempt estimated current return for
your income tax bracket. A taxpayer's marginal tax rate is affected by both  his
taxable  income and  his adjusted gross  income. Locate your  adjusted gross and
your taxable  income  (which  is  your adjusted  gross  income  reduced  by  any
deductions  and  exemptions), then  locate your  tax bracket  based on  joint or
single tax  filing. Read  across  to the  equivalent taxable  estimated  current
return you would need to match the tax-free income.

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

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 772:
    
 
   
       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  772
     (comprising  North Carolina Traditional  Trust 283, California Insured
     Trust 237 and  Florida Insured  Trust 202),  as of  December 7,  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  772
     as  of  December  7,  1994,  in  conformity  with  generally  accepted
     accounting principles.

    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.

    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 September 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.

    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

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.)  A portion of a Unitholder's gain,  to
the extent of accreted market discount, may be treated as ordinary income rather
than capital gain if the Bonds were purchased by a Trust at a market discount or
if  the Unitholder purchased his  or her Units at a  market discount on or after
April 30, 1993. Market discount can arise based on the price the Trust pays  for
the Bonds or the price a Unitholder pays for his or her Units.
 
    In the opinion of Chapman and Cutler, Counsel to the Sponsor, under existing
law:
 
    (1) the  Trusts  are not  associations taxable  as corporations  for Federal
        income tax purposes. Tax-exempt interest received by each of the  Trusts
        on  Bonds  deposited  therein  will  retain  its  status  as  tax-exempt
        interest, for Federal income tax  purposes, when received by the  Trusts
        and  when distributed  to the  Unitholders, except  that the alternative
        minimum tax and  environmental tax (the  "Superfund Tax") applicable  to
        corporate  Unitholders  may, in  certain  circumstances, include  in the
        amount on which  such taxes  are calculated  a portion  of the  interest
        income  received by  the Trust. See  "Certain Tax  Matters Applicable to
        Corporate Unitholders", below;
 
    (2) each Unitholder of a Trust is considered  to be the owner of a pro  rata
        portion  of such Trust under Subpart E, subchapter J of Chapter 1 of the
        Internal Revenue Code of 1986 (the "Code") and will have a taxable event
        when the Trust  disposes of  a Bond or  when the  Unitholder redeems  or
        sells  Units. Unitholders must  reduce the tax basis  of their Units for
        their share of accrued interest received by the Trust, if any, on  Bonds
        delivered  after  the  date the  Unitholders  pay for  their  Units and,
        consequently, such Unitholders may have  an increase in taxable gain  or
        reduction  in capital loss  upon the disposition of  such Units. Gain or
        loss upon the sale or redemption  of Units is measured by comparing  the
        proceeds  of  such sale  or redemption  with the  adjusted basis  of the
        Units. If the  Trustee disposes of  Bonds (whether by  sale, payment  at
        maturity,  redemption or otherwise),  gain or loss  is recognized to the
        Unitholder. The amount of any such gain or loss is measured by comparing
        the Unitholder's  pro  rata  share  of  the  total  proceeds  from  such
        disposition  with  the  Unitholder's  basis for  his  or  her fractional
        interest in  the asset  disposed of.  In the  case of  a Unitholder  who
        purchases Units, such basis (before adjustment for earned original issue
        discount   and  amortized  bond  premium,   if  any)  is  determined  by
        apportioning the  cost of  the  Units among  each  of the  Trust  assets
        ratably  according to value as of the  date of acquisition of the Units.
        The  tax  cost   reduction  requirements  of   said  Code  relating   to
        amortization  of bond premium  may, under some  circumstances, result in
        the Unitholder realizing a taxable gain  when his or her Units are  sold
        or redeemed for an amount equal to their original cost; and
 
    (3) any  amounts paid on defaulted Bonds  held by the Trustee under policies
        of insurance issued with respect to  such Bonds will be excludable  from
        Federal  gross income if, and to the same extent as, such interest would
        have been so excludable if paid by the respective issuer provided  that,
        at  the  time such  policies are  purchased, the  amounts paid  for such
        policies are reasonable, customary and consistent with
 
                                      A-20
<PAGE>
        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 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,
 
                                      A-21
<PAGE>
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 each  Trust  for regularly  evaluating  the Bonds  and for
maintaining surveillance over the portfolio. (See Section 16.)
 
                                      A-22
<PAGE>
    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 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
 
                                      A-23
<PAGE>
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 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  Reserves  may  include  in  its  portfolio
municipal obligations rated Aaa, Aa, MIG-1, VMIG-1 or Prime-1 by Moody's or AAA,
AA,    SP-1    or    A-1    by   Standard    &    Poor's,    unrated   municipal
 
                                      A-25
<PAGE>
obligations that,  in  the  opinion  of  the  investment  adviser,  have  credit
characteristics equivalent to obligations rated as above, tax-exempt obligations
backed  by the U.S. Government, and temporary investments that may be subject to
Federal income tax.
 
THE CALIFORNIA FUND
 
    The California Fund has  the objective of  providing, through investment  in
professionally managed portfolios of California municipal obligations, as high a
level  of current interest income exempt from both Federal and California income
taxes as is consistent with the investment policies of each of the portfolios of
the California Fund  and with  preservation of  capital. Each  portfolio of  the
California  Fund may include  temporary investments that may  be subject to tax.
California Unitholders may reinvest in one of three portfolios of the California
Fund: The Nuveen California Tax-Free  Value Fund, the Nuveen California  Insured
Tax-Free Value Fund and the Nuveen California Tax-Free Money Market Fund.
 
    The  Nuveen California  Tax-Free Value  Fund invests  primarily in long-term
investment grade  California tax-exempt  bonds (I.E.,  bonds rated  in the  four
highest  categories by Moody's  or Standard &  Poor's or, if  unrated, that have
equivalent credit characteristics). The Nuveen California Insured Tax-Free Value
Fund invests  primarily in  the same  type of  investments as  the Special  Bond
Portfolio, each of which is covered by insurance guaranteeing the timely payment
of  principal  and  interest  or  is backed  by  a  deposit  of  U.S. Government
securities.
 
    The Nuveen  California  Tax-Free  Money Market  Fund  invests  primarily  in
high-quality  short term  California tax-exempt money  market instruments (I.E.,
obligations rated in the two highest categories by Moody's or Standard &  Poor's
or,  if unrated,  that have  equivalent credit  characteristics). This portfolio
will include  only  obligations  maturing  within one  year  from  the  date  of
acquisition, will maintain an average maturity of all investments of 120 days or
less, will value its portfolio at amortized cost and will seek to maintain a net
asset value of $1.00 per share. The Nuveen California Tax-Free Money Market Fund
provides for an expedited wire redemption privilege.
 
THE TAX-FREE BOND FUND
 
    The  Tax-Free Bond Fund consists of  the Nuveen Massachusetts Tax-Free Value
Fund, the Nuveen New  York Tax-Free Value Fund,  the Nuveen Ohio Tax-Free  Value
Fund,  and the Nuveen New  Jersey Tax-Free Value Fund,  which are each available
for reinvestment to Unitholders  who are residents of  the state for which  such
portfolio  is  named. The  Tax-Free Bond  Fund has  the objective  of providing,
through investment in a professionally managed portfolio of municipal bonds,  as
high  a level of current interest income exempt both from Federal income tax and
from the  income  tax  imposed  by  each  portfolio's  designated  state  as  is
consistent  with preservation of capital. The  Tax-Free Bond Fund may include in
each of its  portfolios tax-exempt  bonds rated Baa  or BBB  or better;  unrated
bonds   which,  in   the  opinion  of   the  investment   adviser,  have  credit
characteristics equivalent to  bonds rated  Baa or  BBB or  better; and  certain
temporary  investments, including securities the  interest income from which may
be subject to Federal and state income tax.
 
THE INSURED BOND FUND
 
    The Insured Bond Fund  consists of the Nuveen  Insured Municipal Bond  Fund,
the  Nuveen Massachusetts  Insured Tax-Free Value  Fund and the  Nuveen New York
Insured Tax-Free  Value  Fund, which  are  each available  for  reinvestment  to
Unitholders.  (The Massachusetts and  New York Portfolios  are available only to
those Unitholders who  are residents  of the state  for which  the portfolio  is
named.) The Insured Bond Fund has the objective of providing, through investment
in  professionally managed  portfolios of  municipal bonds,  as high  a level of
current interest income exempt from both Federal income tax and, in the case  of
 
                                      A-26
<PAGE>
designated  state portfolios,  from the income  tax imposed  by each portfolio's
designated state, as  is consistent  with preservation of  capital. The  Insured
Bond  Fund may include in each of its portfolios the same type of investments as
the Tax-Free Bond Fund, each of  which is covered by insurance guaranteeing  the
timely  payment of  principal and  interest or  is backed  by a  deposit of U.S.
Government securities.
 
THE MONEY MARKET FUND
 
    The Money Market Fund  consists of the  Nuveen Massachusetts Tax-Free  Money
Market  Fund and the Nuveen New York  Tax-Free Money Market Fund, which are each
available for reinvestment  to Unitholders who  are residents of  the state  for
which  such portfolio is named. The Money Market Fund includes in its portfolios
only obligations  maturing  within  one  year  from  the  date  of  acquisition,
maintains  an average  maturity of  120 days or  less, values  its portfolios at
amortized cost and seeks to maintain a  net asset value of $1.00 per share.  The
Money  Market  Fund  has  the  objective  of  providing,  through  investment in
professionally  managed  portfolios   of  high   quality  short-term   municipal
obligations, as high a level of current interest income exempt both from Federal
income  tax and from the income tax imposed by each portfolio's designated state
as is consistent with stability of  principal and the maintenance of  liquidity.
The  Money  Market  Fund  may  include  in  each  of  its  portfolios  municipal
obligations rated Aaa, Aa, MIG-1, MIG-2, VMIG-1,  VMIG-2, Prime 1 or Prime 2  by
Moody's  or  AAA, AA,  SP-1,  SP-2, A-1  or A-2  by  Standard &  Poor's; unrated
municipal obligations  that, in  the  opinion of  the investment  adviser,  have
credit  characteristics equivalent to obligations  rated as above; and temporary
investments that may be subject to Federal and state income tax.
 
THE MULTISTATE TRUST
 
    The Multistate Trust consists of the Nuveen Arizona Tax-Free Value Fund, the
Nuveen Florida Tax-Free Value Fund, the Nuveen Maryland Tax-Free Value Fund, the
Nuveen Michigan Tax-Free Value Fund, the Nuveen New Jersey Tax-Free Value  Fund,
the  Nuveen Pennsylvania  Tax-Free Value Fund  and the Nuveen  Virginia Tax Free
Value Fund, which  are each available  for reinvestment to  Unitholders who  are
residents  of the state for which such  portfolio is named. The Multistate Trust
has the objective of providing,  through investment in a professionally  managed
portfolio  of municipal bonds, as high a level of current interest income exempt
from both regular Federal  income tax and the  applicable state personal  income
tax  as is  consistent with  preservation of  capital. The  Multistate Trust may
include in  each of  its portfolios  tax-exempt bonds  rated "Baa"  or "BBB"  or
better,  unrated bonds  which, in  the opinion  of the  investment advisor, have
credit characteristics  equivalent to  bonds  rated "baa"  or "BBB"  or  better,
limited  to  no more  than 20%  of  the Multistate  Trust's assets,  and certain
temporary investments that may be subject to Federal and state income tax.
 
    Each person who purchases Units of a  Trust may become a participant in  the
Accumulation  Plan and elect  to have his  or her distributions  on Units of the
Trust invested directly in shares of one of the Accumulation Funds.  Reinvesting
Unitholders   may  select  any  interest  distribution  plan.  Thereafter,  each
distribution  of  interest  income  or  principal  on  the  participant's  Units
(principal  only in  the case of  a Unitholder  who has chosen  to reinvest only
principal distributions) will, on the applicable distribution date, or the  next
day  on which the New  York Stock Exchange is  normally open ("business day") if
the distribution  date is  not  a business  day,  automatically be  received  by
Shareholder  Services, Inc., transfer agent for  each of the Accumulation Funds,
on behalf of such participant  and applied on that  date to purchase shares  (or
fractions  thereof)  of  the Accumulation  Fund  chosen  at net  asset  value as
computed as of 4:00 p.m. eastern time on each such date. All distributions  will
be  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.
 
                                      A-27
<PAGE>
    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
 
                                      A-28
<PAGE>
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:

</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 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
 
                                      A-29

 *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 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
 
                                      A-30
<PAGE>
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 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,
 
                                      A-31
<PAGE>
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.
 
                                      A-33
<PAGE>
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
trust office at  770 Broadway,  New York, New  York 10003.  United States  Trust
Company  of New York, established in  1853, has, since its organization, engaged
primarily in the  management of trust  and agency accounts  for individuals  and
corporations. The Trustee is a member of the New York Clearing House Association
and  is subject to supervision and examination by the Superintendent of Banks of
the State of New York, the  Federal Deposit Insurance Corporation and the  Board
of  Governors of the Federal Reserve System.  In connection with the storage and
handling of  certain Bonds  deposited in  the Trusts,  the Trustee  may use  the
services of The
 
                                      A-34
<PAGE>
Depository  Trust Company. These services would include safekeeping of the Bonds

services.  The  Depository  Trust Company  is  a limited  purpose  trust company
organized under  the Banking  Law of  the State  of New  York, a  member of  the
Federal  Reserve System  and a clearing  agency registered  under the Securities

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.

under management.  Nationwide, more  than  1,000,000 individual  investors  have
purchased  Nuveen's tax  exempt trusts  and funds.  The present  corporation was
organized in 1967 as a wholly-owned subsidiary of Nuveen Corporation,  successor
to  the original John Nuveen & Co. founded  in 1898 as a sole proprietorship and
incorporated in  1953.  In  1974,  John  Nuveen  &  Co.  Incorporated  became  a
wholly-owned  subsidiary of The  St. Paul Companies,  Inc., a financial services
management company  located in  St. Paul,  Minnesota. On  May 19,  1992,  common
shares  comprising a  minority interest  in The  John Nuveen  Company ("JNC"), a
newly organized corporation which holds all  of the shares of Nuveen, were  sold
to  the  general  public in  an  initial  public offering.  St.  Paul  retains a
controlling interest in  JNC with over  70% of  JNC's shares. The  Sponsor is  a
member  of  the  National  Association  of  Securities  Dealers,  Inc.  and  the
Securities Industry Association and has its principal offices located in Chicago
(333 W. Wacker Drive) and New York  (Swiss Bank Tower, 10 East 50th Street).  It
maintains 14 regional offices.
 
24.  OTHER INFORMATION
AMENDMENT OF INDENTURE
 
    The  Indenture may  be amended  by the Trustee  and the  Sponsor without the
consent of any of  the Unitholders (1)  to cure any ambiguity  or to correct  or
supplement  any provision thereof which may be defective or inconsistent, or (2)
to make such  other provisions as  shall not adversely  affect the  Unitholders,
provided,  however, that the Indenture may not be amended to increase the number
of Units in any Trust or to permit the deposit or acquisition 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.

*As published by the rating companies.
 
                                      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
 
                                      A-40
<PAGE>
parallel  with  Aaa  and  Aa  obligations,  with  the  occasional  exception  of
oversupply in a few specific instances.
 
    Moody's bond rating  symbols may  contain numerical modifiers  of a  generic
rating  classification. The modifier 1 indicates that the bond ranks at the high
end of  its category;  the modifier  2 indicates  a mid-range  ranking; and  the
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
 
    Baa--Bonds  which are rated Baa are  considered as medium grade obligations,
i.e., they are neither  highly protected nor  poorly secured. Interest  payments
and  principal security appear  adequate for the  present but certain protective
elements may be lacking or may  be characteristically unreliable over any  great
length  of time. Such  bonds lack outstanding  investment characteristics and in
fact have speculative  characteristics as  well. The market  value of  Baa-rated
bonds  is more  sensitive to changes  in economic circumstances,  and aside from
occasional speculative factors applying to some bonds of this class, Baa  market
valuations  move in parallel  with Aaa, Aa  and A obligations  during periods of
economic normalcy, except in instances of oversupply.
 
    Con. (--)--Bonds for which the security depends upon the completion of  some
act  or the  fulfillment of  some condition  are rated  conditionally. These are
bonds secured by (a)  earnings of projects under  construction, (b) earnings  of
projects  unseasoned  in  operation  experience, (c)  rentals  which  begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes  probable credit stature upon  completion
of construction or elimination of basis of condition.
 
    NOTE RATINGS:
 
    MIG 1--This  designation  denotes  best  quality.  There  is  present strong
           protection by established cash  flows, superior liquidity support  or
           demonstrated broad-based access to the market for refinancing.
 
    MIG 2--This  designation  denotes high  quality.  Margins of  protection are
           ample although not so large as in the preceding group.

information and structure of the attached final Prospectus will be 
substantially the same as that of the final Prospectus for this Series.  
Although the attached Prospectus includes trusts as indicated

differ from such trusts.  Information with respect to the actual trusts to
be included, pricing, the number of Units, dates and summary information

previous Series should be considered as being included for informational 
purposes only.  Ratings of the securities in this Series are expected to be
comparable to those of the securities deposited in the previous Series.
However, the Estimated Current Return for this Series will depend on the
