    Massachusetts  Insured Trust  134 (the "Trust")  consists of  a portfolio of
interest-bearing  obligations  issued  by   or  on  behalf   of  the  State   of
Massachusetts,  certain United  States Territories or  authorities and political
subdivisions thereof which,  in the opinion  of recognized bond  counsel to  the
issuing  authorities, provide income which is exempt from Federal income tax and
Massachusetts income tax, to the extent indicated below.
    
    The objectives of the Trust are income exempt from Federal and state  income
taxes,  and conservation  of capital. The  objectives are,  of course, dependent
upon the continuing  ability of the  issuers, obligors and/or  insurers to  meet
their respective obligations.
   
    The  Portfolio of  the Trust  consists of  6 obligations  issued by entities
located in Massachusetts and one obligation  issued by an entity located in  the
Territory  of Puerto Rico. The Bonds in the Trust are either general obligations
of the  governmental entity  issuing them  and are  backed by  the taxing  power
thereof  or  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 the Bonds are divided as follows:

    Approximately  14.9% of the  aggregate principal amount of  the Bonds in the
Trust (accounting for approximately 13.6% of the aggregate offering price of the
Bonds) are original issue discount bonds. See  "RISK FACTORS" in Part B of  this
Prospectus  for a discussion  of the characteristics of  such obligations and of
the risks associated therewith.
    
    All of the Bonds in the Trust are covered by policies of insurance  obtained
from  the  MBIA  Insurance  Corporation guaranteeing  payment  of  principal and
interest when due. As a  result of such insurance, the  Bonds in the Trust  have
received  a rating of "Aaa" by  Moody's and both the Bonds  in the Trust and the
Units of the Trust have received a rating of "AAA" by Standard & Poor's.
   
    The Trust is considered to be concentrated in Bonds of Health Care  Facility
Revenue  Issuers whose revenues are subject to certain risks including increased
governmental regulation, fluctuating occupancy levels and increased competition.
For a  discussion of  the risks  associated  with investments  in the  bonds  of
various issuers, see "RISK FACTORS" in Part B of this Prospectus.

The  evaluation time for purpose  of sale, purchase or  redemption of Units is 4
p.m. Eastern time or as of  any earlier closing time on  a day on which the  New
York  Stock Exchange is scheduled in advance to close at such earlier time. (See
"HOW IS THE PUBLIC OFFERING PRICE DETERMINED?" in Part B of this Prospectus.)
 
   
(1) Units are offered at  the Public Offering Price  plus accrued interest  from
    the  preceding Record  Date to,  but not  including, the  date of settlement
    (normally three business days  after purchase). The Date  of Deposit of  the
    Fund  has  been  designated  as  the First  Record  Date  for  all  plans of
    distribution of the Trust and, accordingly, for Units purchased on the  Date
    of Deposit, $.07 of accrued interest to the Settlement Date will be added to
    the  Public Offering Price.  (See "WHAT IS  ACCRUED INTEREST?" in  Part B of
    this Prospectus.)
    
 
(2) The Average Maturity  of Bonds  in the Trust  is calculated  based upon  the
    stated  maturities of the Bonds in the  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
    Bonds  in the  Trust may  increase or  decrease from  time to  time as Bonds
    mature or are called or sold.
 
(3) Assumes delivery of  all Bonds.  (See "COMPOSITION OF  TRUSTS" appearing  in
    Part  B of this  Prospectus.) Interest income does  not include accretion of
    original issue  discount on  "zero coupon"  Bonds, Stripped  Obligations  or
    other  original issue discount Bonds. (See "RISK  FACTORS" in Part B of this
    Prospectus.)
 
(4) The amount and  timing of interest  distributions from the  Trust under  the
    various  plans of distribution  are set forth below.  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. The amount of interest to
    be distributed  annually  per  Unit,  will generally  change  as  Bonds  are
    redeemed, mature or are sold or as fees and expenses increase or decrease.
 
(5) Estimated  Long  Term Return  for the  Trust represents  the average  of the
    yields to  maturity  (or  call)  of  the  Bonds  in  the  Trust's  portfolio
    calculated  in  accordance  with  accepted bond  practices  and  adjusted to
    reflect a compounding factor, expenses and sales charges. Estimated  Current
    Return  is computed by dividing  the Net Annual Interest  Income per Unit by
    the Public Offering  Price, and in  contrast to Estimated  Long Term  Return
    does  not reflect the  amortization of premium or  accretion of discount, if
    any. For  more information  see "WHAT  ARE ESTIMATED  LONG TERM  RETURN  AND
    ESTIMATED CURRENT RETURN?" in Part B of this Prospectus.
 
(6) Each  Trustee annual  fee is per  $1,000 principal amount  of the underlying
    Bonds in  the  Trust  for  that  portion of  the  Trust  that  represents  a
    particular plan of distribution.
 
(7) The  Trust (and  therefore Unitholders)  will bear all  or a  portion of its
    organizational  costs  (including  costs   of  preparing  the   registration
    statements,  the trust  indenture and  other closing  documents, registering
    Units with the Securities  and Exchange Commission  and states, the  initial
    audit  of the Trust portfolio, legal fees  and the initial fees and expenses
    of the Trustee but  not including the expenses  incurred in the printing  of
    preliminary and final prospectuses, and expenses incurred in the preparation
    and  printing of  brochures and  other advertising  materials and  any other
    selling expenses)  as  is  common for  mutual  funds.  Total  organizational
    expenses  will be amortized  over a five  year period. See  "WHAT ARE NORMAL
    TRUST OPERATING EXPENSES?" in  Part B of this  Prospectus and "Statement  of
    Condition."  Historically, the sponsors of  unit investment trusts have paid
    all the costs of establishing such trusts.

                           MASSACHUSETTS RISK FACTORS
 
    The  financial condition of the Commonwealth of Massachusetts is affected by
various national, economic,  social and environmental  policies and  conditions.
Additionally,  limitations  imposed by  statute  and voter  initiative  upon the
Commonwealth and its local governments  concerning taxes, bond indebtedness  and
other  matters may constrain the revenue-generating capacity of the Commonwealth
and its local  governments and,  therefore, the ability  of the  issuers of  the
Bonds to satisfy their obligations.
 
    The  economic vitality of the State  and its various regions and, therefore,
the ability of the  State and its  local governments to  satisfy the Bonds,  are
affected  by numerous factors.  The employment in the  Commonwealth has been and
continues to be significantly  and adversely affected  by reductions in  federal
government  spending on  defense-related industries.  The Commonwealth  has many
material future  liabilities, including  an  underfunded retirement  system  and
Medicaid expenditures.
 
    The  Commonwealth is a party to numerous  lawsuits in which an adverse final
decision could materially affect the Commonwealth's governmental operations  and
consequently its ability to pay debt service on its obligations.
 
    In  recent  years, the  Commonwealth and  certain of  its public  bodies and
municipalities have faced serious financial difficulties which have affected the
credit standing  and borrowing  abilities of  Massachusetts and  its  respective
entities  and may have contributed to higher interest rates on debt obligations.
Standard  and  Poor's  currently  rates  the  Commonwealth's  uninsured  general
obligation bonds at A+, while Moody's rates these obligations at A1.
 
    Further  information concerning  Massachusetts risk factors  may be obtained
upon written  or  telephonic request  to  the  Trustee as  described  in  "OTHER
INFORMATION -- Supplemental Information" appearing in Part B of this Prospectus.
 
                    TAX STATUS--MASSACHUSETTS INSURED TRUST
 
    For  a discussion of the Federal tax status of income earned on Trust Units,
see "WHAT  IS THE  TAX  STATUS OF  UNITHOLDERS?" appearing  in  Part B  of  this
Prospectus.
 
    In  the opinion  of Edwards &  Angell, special Massachusetts  counsel to the
Trust, based on rulings by the Commissioner of Revenue and under existing law:
 
    For Massachusetts  income tax  purposes, each  Trust will  be treated  as  a
corporate  trust under Section 8 of Chapter 62 of the Massachusetts General Laws
("M.G.L.") and not as a grantor trust under Section 10(e) of M.G.L. Chapter 62.
 
    The Trust  will not  be held  to be  engaging in  business in  Massachusetts
within  the meaning  of said Section  8 and  will, therefore, not  be subject to
Massachusetts income tax.
 
    Unitholders who are  subject to Massachusetts  income taxation under  M.G.L.

issued  by Massachusetts,  its counties,  municipalities, authorities, political
subdivisions or instrumentalities or by  Puerto Rico, the Virgin Islands,  Guam,

("Massachusetts Obligations").
 
    Unitholders  who are subject  to Massachusetts income  taxation under M.G.L.
Chapter 62  will not  be required  to  include their  respective shares  of  the
earnings  of or distributions from the Trust in their Massachusetts gross income
to the extent that such earnings or distributions are derived from the  proceeds
of  insurance  obtained  by  the  Sponsor  of the  Trust  or  by  the  issuer or
underwriter of an obligation held by the Trust that represent maturing  interest
on  defaulted obligations held  by the Trustee,  if and to  the same extent that
such earnings or distributions would have been excludable from the gross  income
of such Unitholders if derived from interest paid by the issuer of the defaulted
obligation.
 
    Unitholders  which are corporations subject to taxation under M.G.L. Chapter
63 will be required  to include their  respective shares of  the earnings of  or
distributions  from the Trust in their  Massachusetts gross income to the extent
that such  earnings or  distributions represent  interest from  bonds, notes  or
indebtedness of any state, including Massachusetts, except for interest which is
specifically  exempted from  such tax by  the acts authorizing  issuance of said
Massachusetts Obligations.
 
    The Trust's capital gains and/or capital losses which are includable in  the
Federal  gross income  of Unitholders  who are  subject to  Massachusetts income
taxation under M.G.L. Chapter 62, or Unitholders which are corporations  subject
to  Massachusetts taxation under  M.G.L. Chapter 63 will  be included as capital
gains and/or losses in the  Unitholders' Massachusetts gross income, except  for
capital gain which is specifically exempted from taxation under such Chapters by
the acts authorizing issuance of said Massachusetts Obligations.
 
    Unitholders  which are corporations  subject to tax  under M.G.L. Chapter 63
and which are tangible property corporations will not be required to include the
Units when determining the value  of their tangible property. Unitholders  which
are  intangible property corporations will be required to include the Units when
determining their net worth.
 
    Gains or losses realized on sales or redemptions of Units by Unitholders who
are subject  to  Massachusetts  income  taxation under  M.G.L.  Chapter  62,  or
Unitholders  which  are corporations  subject  to Massachusetts  income taxation
under M.G.L. Chapter 63, will be includable in their Massachusetts gross income.
In determining such gain or loss  Unitholders will, to the same extent  required
for  Federal tax purposes,  have to adjust  their tax bases  for their Units for
accrued interest received, if any, on Massachusetts Obligations delivered to the
Trustee after the Unitholders pay for their Units, for amortization of premiums,
if any, on Massachusetts Obligations held by the Trust, and for accrued original
issue discount with respect to each Massachusetts Obligation which, at the  time
the Massachusetts Obligation was issued, had original issue discount.
 
    The  Units  of the  Trust  are not  subject to  any  property tax  levied by
Massachusetts or any political subdivision thereof, nor to any income tax levied
by any such political subdivision. They are includable in the gross estate of  a
deceased  holder  who  is  a  resident  of  Massachusetts  for  purposes  of the
Massachusetts Estate Tax.

    (1) The Sponsor's contracts to purchase  Bonds were entered into during  the
period  from March 20, 1996  to March 21, 1996.  Other information regarding the
Bonds in the Trust on the Date of Deposit is as follows:

In addition,  the difference  between the  Trustee's determination  of  Offering
Price  and Bid Price (as a percentage of principal amount) is .48%. 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.  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.
 
    (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 specified in  the instruments setting forth the  terms
and  provisions of  such Bonds.  See "COMPOSITION OF  TRUSTS", "WHAT  IS THE TAX
STATUS OF UNITHOLDERS?" and "RISK FACTORS" in Part B of this Prospectus.
 
    (3) All the  Bonds in the  Insured Trusts,  as insured by  the Insurer,  are
rated AAA by Standard & Poor's and Aaa by Moody's. The insurance obtained by the
Trust guarantees the payment of interest and principal on the Bonds when due but
does not cover certain market risks associated with fixed income securities such
as  accelerated payments, premiums payable  on mandatory redemptions or interest
rate risks.  (See "WHY  AND  HOW ARE  THE  BONDS INSURED?"  in  Part B  of  this
Prospectus and "Description of Ratings" in the Information Supplement.)

(1) Represented  by contracts to  purchase Tax-Exempt Bonds  which include "when
    issued" or  "regular  way" or  "delayed  delivery" contracts  for  which  an
    irrevocable  letter of  credit issued  by a  major commercial  bank has been
    deposited with the Trustee on the Date of Deposit. The amount of such letter
    of credit  and any  cash  deposited exceeds  the  amount necessary  for  the
    purchase  of the Bonds plus accrued interest  to the Date of Deposit. At the
    Date of Deposit, Bonds  may have been delivered  to the Sponsor pursuant  to
    certain  of these contracts; the Sponsor has  assigned to the Trustee all of
    its rights, title and interest in and to such Bonds.
 
(2) Aggregate value (at offering prices) as of the Date of Deposit of the  Bonds
    listed  under "Schedule of Investments" herein,  and their aggregate cost to
    the Trust are the  same. Such offering prices  were determined by Kenny  S&P
    Evaluation  Services, a division of J.J. Kenny Co., Inc., as of the close of
    business on the business day prior to the Date of Deposit. (See "HOW WAS THE
    PRICE OF THE BONDS  DETERMINED AT THE  DATE OF DEPOSIT?" in  Part B of  this
    Prospectus.)  Insurance coverage providing for the timely payment, when due,
    of all principal of and interest on  the Bonds in an Insured Trust 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) The Trust (and  therefore Unitholders)  will bear all  or a  portion of  its
    estimated  organizational costs  which will  be deferred  and amortized over
    five years from the Date of Deposit.
 
(4) Representing, as set forth in "WHAT IS ACCRUED INTEREST?" in Part B of  this
    Prospectus,  advancement by  the Trustee of  an amount equal  to the accrued
    Bond interest as of the Date of Deposit.
 
(5) Aggregate Public Offering Price (exclusive of accrued interest) computed  as
    set  forth under "HOW IS THE PUBLIC OFFERING PRICE DETERMINED?" in Part B of
    this Prospectus.
 
(6) The gross underwriting commission of 4.90% of the Public Offering Price  has
    been  calculated on the assumption that the  Units sold are not subject to a
    reduction of sales  charge for  quantity purchases.  In single  transactions
    involving  500 Units or more, the sales  charge is reduced. (See "HOW IS THE
    PUBLIC OFFERING PRICE DETERMINED?" in Part B of this Prospectus.)

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
   
TO THE BOARD OF DIRECTORS OF JOHN  NUVEEN & CO. INCORPORATED AND UNITHOLDERS  OF
MASSACHUSETTS INSURED TRUST 134:
    
 
   
    We  have audited the accompanying statement of condition and the schedule of
investments at  date of  deposit (included  in  Part A  of this  Prospectus)  of
Massachusetts Insured Trust 134 (contained in Nuveen Tax-Free Unit Trust, Series
853), as of March 22, 1996. These financial statements are the responsibility of
the  Sponsor. Our  responsibility is  to express  an opinion  on these financial
statements based on our audit.
    
 
    We conducted  our  audit  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   statement  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
audit provides a reasonable basis for our opinion.
 
   
    In our opinion, the statement of  condition and the schedule of  investments
at  date of deposit referred to above  present fairly, in all material respects,
the financial position of Massachusetts Insured Trust 134 as of March 22,  1996,
in conformity with generally accepted accounting principles.

              SEPTEMBER 1, 1995
 
THIS PART B OF THE PROSPECTUS MAY NOT BE DISTRIBUTED UNLESS ACCOMPANIED BY  PART
A. BOTH PARTS OF THIS PROSPECTUS SHOULD BE RETAINED FOR FUTURE REFERENCE.
FURTHER  DETAIL REGARDING CERTAIN OF THE  INFORMATION PROVIDED IN THE PROSPECTUS
MAY BE OBTAINED WITHIN  FIVE BUSINESS DAYS OF  WRITTEN OR TELEPHONIC REQUEST  TO

INTEREST  INCOME TO A TRUST 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.
 
THIS  NUVEEN TAX-EXEMPT  UNIT TRUST SERIES  consists of  the underlying separate
unit investment  trust  set forth  in  Part A  to  this Prospectus.  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  "Schedule of  Investments"
appearing  in Part A of this Prospectus).  Except in specific instances as noted
in Part A of  this Prospectus, the  information contained in  this Part B  shall
apply  to each Trust in its entirety.  All obligations in each Traditional Trust
are rated in the category "A" or better by Standard & Poor's, a division of  the
McGraw  Hill Companies ("Standard & Poor's")  or Moody's Investors Service, Inc.
("Moody's") on the Date  of Deposit. All obligations  in each Insured Trust  are
covered  by policies of  insurance obtained from  the MBIA Insurance 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 and the Bonds  in the Insured Trusts  and
the  Units of  each such  Trust have received  a rating  of "AAA"  by Standard &
Poor's. INSURANCE RELATES ONLY TO THE BONDS IN THE INSURED TRUSTS AND NOT TO THE
UNITS OFFERED HEREBY OR TO THEIR MARKET  VALUE. (See "WHY AND HOW ARE THE  BONDS
INSURED?".)
 
THE  OBJECTIVES of  a Trust  are tax-exempt  income and  conservation of capital
through a diversified investment  in tax-exempt Bonds.  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 a Trust's objectives will be
achieved. (See "RISK FACTORS".)
 
DISTRIBUTIONS of interest received by a Trust will be made semi-annually  unless
the  Unitholder  elects to  receive them  monthly or  quarterly. (See  "WHEN ARE
DISTRIBUTIONS MADE TO  UNITHOLDERS?".) 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 Part A of this
Prospectus and  "WHAT  ARE ESTIMATED  LONG  TERM RETURN  AND  ESTIMATED  CURRENT
RETURN?".)
 
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 "HOW IS THE PUBLIC
OFFERING  PRICE DETERMINED?".)  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 three
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 "HOW IS THE PUBLIC OFFERING PRICE DETERMINED?".)
 
A  UNITHOLDER MAY REDEEM UNITS at the office of the Trustee 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 "HOW  UNITS MAY BE REDEEMED  WITHOUT
CHARGE?".)  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 "MARKET  FOR UNITS".) RETAIN  BOTH

WHAT IS THE NUVEEN TAX-EXEMPT UNIT TRUST?
 
This 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. The underlying unit investment trusts contained in this
Series  are  combined  under  one   Trust  Indenture  and  Agreement.   Specific
information  regarding this Trust is set forth in Part A of this Prospectus. The
various Nuveen Tax-Exempt Unit 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 the Date of
Deposit (the "Indenture") between John Nuveen & Co. Incorporated (the "Sponsor")
and The Chase Manhattan Bank, N.A. (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) (the "Bonds"). See "Schedule  of Investments" in Part A
of this Prospectus, for  a description of the  Securities deposited in a  Trust.
See  "SUMMARY OF PORTFOLIOS" and "RISK FACTORS"  for a discussion of zero coupon
bonds and  stripped obligations  included in  the Trusts,  if any.  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 "Schedule of  Investments" in Part  A of this
Prospectus and  "COMPOSITION  OF TRUSTS".  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 "COMPOSITION OF TRUSTS."
 
    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 "WHY AND HOW  ARE THE BONDS INSURED?".) 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 which  represent
ownership  of  the  entire  Trust,  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 set forth in "Essential
Information" in Part A of this Prospectus.  Units may only be sold in states  in
which  they  are registered.  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.
 
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  and  certain  state  income  tax and
intangibles taxes, if any, for purchasers who qualify as residents of that State
in which Bonds are issued. 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 MBIA  Insurance
Corporation,  and as a result  of such insurance the  obligations in the Insured
Trusts are rated "Aaa" by Moody's and "AAA" by Standard & Poor's. (See "WHY  AND
HOW  ARE THE  BONDS INSURED?".)  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  or Moody's (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. 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  the Appendices to  the
Information Supplement of this Prospectus.
 
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 "WHAT ARE
THE OBJECTIVES OF THE TRUSTS?" 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 MBIA Insurance Corporation insurance on
such Bonds. (See "WHY AND HOW ARE THE BONDS INSURED?".)

RISK FACTORS
 
    An  investment in Units of any Trust should be made with an understanding of
the risks that such an investment may entail. Each Trust consists of  fixed-rate
municipal  debt  obligations. As  such, 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. The Sponsor cannot  predict
the  extent or timing  of such fluctuations and,  accordingly, their effect upon
the value of the debt obligations.  Additional risk factors include the  ability
of  the issuer, or, if applicable, an  insurer, to make payments of interest and
principal when  due, "mandatory  put" features,  early call  provisions and  the
potential  for changes in the tax status of the Bonds. As set forth in Part A of
this Prospectus, the Trusts may contain or be concentrated in one or more of the
types of bonds discussed below. The following paragraphs briefly 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,  and
which  also  therefore 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. The Bonds
described  below  may  be  subject   to  special  or  extraordinary   redemption
provisions.  For economic risks specific to the individual Trusts, see Part A of
this Prospectus  and  the  Appendices  to the  Information  Supplement  of  this
Prospectus.
 
    HEALTH  FACILITY OBLIGATIONS are  obligations of issuers  whose revenues are
derived from services  provided by  hospitals or other  health care  facilities,
including  nursing  homes. The  ability  of such  issuers  to make  debt service
payments on  these  obligations  is  dependent  on  various  factors,  including
occupancy  levels  of the  facility, demand  for  services, wages  of employees,
overhead  expenses,  competition  from   other  similar  providers,   government
regulation,  the cost of  malpractice insurance, and  the degree of governmental
financial assistance, including Medicare and Medicaid.
 
    HOUSING OBLIGATIONS are obligations of issuers whose revenues are  primarily
derived  from mortgage loans on single family residences or housing projects for
low to moderate income families. Housing obligations are generally prepayable at
any time and  therefore their average  life will ordinarily  be less than  their
stated  maturities. The ability of such issuers to make debt service payments on
these obligations is dependent on  various factors, including occupancy  levels,
rental  income, mortgage default rates,  taxes, operating expenses, governmental
regulations and the appropriation of subsidies.
 
    INDUSTRIAL  REVENUE  OBLIGATIONS  are  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. Debt  service  payment on  IRBs  is dependent  upon  various  factors,
including  the creditworthiness of the corporate operator of the project and, if
applicable, corporate guarantor, revenues  generated from the project,  expenses
associated with the project and regulatory and environmental restrictions.
 
    ELECTRIC  UTILITY OBLIGATIONS are obligations  of issuers whose revenues are
primarily derived from the sale of electric energy. The ability of such  issuers
to  make  debt service  payments on  these obligations  is dependent  on various
factors, including the rates  for electricity, the  demand for electricity,  the
degree  of competition, governmental regulation,  overhead expenses and variable
costs, such as fuel.
 
    TRANSPORTATION FACILITY REVENUE OBLIGATIONS are 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 ability of issuers
to make  debt  service payments  on  airport  obligations is  dependent  on  the
capability  of airlines to  meet their obligations under  use agreements. Due to
increased competition,  deregulation, increased  fuel costs  and other  factors,
many  airlines may  have difficulty  meeting their  obligations under  these use
agreements. 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. The revenue of issuers of transit system obligations will
be affected by variations in utilization, which  in turn may be affected by  the
degree  of  local governmental  subsidization, competition  from other  forms of
transportation, and  increased costs.  Port  authorities derive  their  revenues
primarily  from fees imposed  on ships using the  facilities which may fluctuate
depending on  the local  economy  and on  competition  from competing  forms  of
transportation  such  as air,  rail and  trucks. The  revenues of  issuers which
derive their  payments  from bridge,  road  or  tunnel toll  revenues  could  be
adversely  affected  by  increases  in fuel  costs,  competition  from toll-free
vehicular bridges and roads and alternative modes of transportation.
 
    WATER AND/OR SEWERAGE OBLIGATIONS are obligations of issuers whose  revenues
are  payable from user fees from the sale of water and/or sewerage services. The
problems   of   such    issuers   include   the    ability   to   obtain    rate
 
                                       4
<PAGE>
increases,  population  declines, the  limitations  on operations  and increased
costs and delays attributable to environmental considerations, the  difficulties
obtaining  new supplies of fresh water,  the effect of conservation programs and
in "no-growth" zoning ordinances.
 
    UNIVERSITY AND COLLEGE REVENUE OBLIGATIONS are obligations of issuers  whose
revenues  are  derived  mainly  from  tuition,  dormitory  revenues,  grants and
endowments. General  problems faced  by  such issuers  include declines  in  the
number  of "college" age  individuals, possible inability  to raise tuitions and
fees, 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.
 
    DEDICATED-TAX SUPPORTED  OBLIGATIONS are  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  OBLIGATIONS  are  obligations that  are  secured  by lease
payments of a  governmental entity  and 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 OBLIGATIONS AND STRIPPED OBLIGATIONS are bonds which
were  issued with  nominal interest  rates less than  the rates  then offered by
comparable securities and as  a consequence were originally  sold at a  discount
from  their face,  or par,  values. 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 obligations 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.  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  obligations, 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  "Schedule of  Investments"  appearing in  Part A  of  this
Prospectus 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 ("Stripped Obligations").  Each
Stripped  Obligation has been purchased at a discount from the amount payable at
maturity. A Stripped Obligation  therefore has economic characteristics  similar
to zero coupon bonds, as described above.
 
    Unitholders  should consult their own tax advisers with respect to the state
and local tax consequences of owning  original issue discount bonds or  Stripped
Obligations.  Under applicable  provisions governing determination  of state and
local taxes,  interest  on  original  issue  discount  obligations  or  Stripped
Obligations  may be  deemed to be  received in  the year of  accrual even though
there is no corresponding cash payment.
 
                                       5
<PAGE>
    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.  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.
 
COMPOSITION OF TRUSTS
 
Each Trust initially consists  of delivery statements  relating to contracts  to
purchase  Bonds (or of such Bonds) as are listed under "Schedule of Investments"
in Part A of this Prospectus 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  a  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. 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  believes it  unlikely, 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  in Part  A of  this Prospectus  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 in Part A of this Prospectus (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" in Part A of this Prospectus. 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 "Schedule of Investments" in Part A of
this Prospectus.
 
    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 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  must satisfy the  criteria previously  described for the
Trusts and shall be substantially identical to the Failed Bonds they replace  in
terms  of (i) the exemption from federal  and state taxation; (ii) maturity and;
(iii) cost to the Trust. In addition,  Replacement Bonds 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.
 
    To  the extent Replacement Bonds are  not acquired, 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 "Schedule of Investments"  in Part A of
 
                                       6
<PAGE>
this Prospectus  and  in  most  cases  pursuant  to  sinking  fund,  special  or
extraordinary  redemption provisions. 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.  The exercise of redemption  or call provisions is
more likely to occur in  situations where when the  Bonds have an offering  side
evaluation  which represents a premium  over par (as opposed  to a discount from
par). (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  "WHAT IS THE TAX STATUS OF  UNITHOLDERS?" and "WHEN ARE DISTRIBUTIONS MADE
TO UNITHOLDERS?" in Part B and the  "Schedule of Investments" in Part A of  this
Prospectus.)
 
    CERTAIN  TAX  MATTERS;  LITIGATION.    Certain of  the  Bonds  in  a Trust's
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.
 
WHY AND HOW ARE THE BONDS INSURED?
 
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 the Bonds from the MBIA Insurance Corporation
(the "Insurer"). Certain of the  Bonds in an 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 claims-paying ability of both
the Insurer  and the  Association was  rated  "AAA Prime  Grade" by  Standard  &
Poor's.  Moody's rates  all bond  issuers insured by  either the  Insurer or the
Association "Aaa" and  short-term loans "MIG  1," both designated  to be of  the
highest  quality.  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).
 
    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 and/or  "AAA" by  Standard  & Poor's  in recognition  of such
insurance.
 
                                       7
<PAGE>
    If a Bond in a Traditional  Trust is insured, the "Schedule of  Investments"
appearing in Part A of this Prospectus will identify the insurer. The Sponsor to
date  has purchased  and presently  intends to  purchase insurance  for Bonds in
Traditional Trusts exclusively from the Insurer. There can be no assurance  that
any  insurer listed therein will be able to satisfy its commitments in the event
claims are made in  the future. However, Standard  & Poor's and/or Moody's  have
rated the claims-paying ability of each insurer "AAA" or "Aaa," respectively.
 
    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, the  Commonwealth of  Puerto Rico,  the Commonwealth  of the  Northern
Mariana  Islands, the Virgin Islands  of the United States  and the Territory of
Guam. The Insurer has one European branch in the Republic of France.
 
    As of  June  30,  1995 the  Insurer  had  admitted assets  of  $3.6  billion
(unaudited),  total liabilities of  $2.4 billion (unaudited),  and total capital
and surplus of $1.2 billion (unaudited) determined in accordance with  statutory
accounting   practices   prescribed   or  permitted   by   insurance  regulatory
authorities. As of December  31, 1994, the Insurer  had admitted assets of  $3.4
billion  (audited),  total  liabilities  of $2.3  billion  (audited),  and total
capital and  surplus of  $1.1 billion  (audited) determined  in accordance  with
statutory  accounting practices prescribed or  permitted by insurance regulatory
authorities.
 
    The Association is comprised  of the five insurance  companies set forth  in
the following table, which provides certain unaudited financial information with
respect to each of the five insurance companies comprising the Association.

    Insurance  companies  are subject  to  extensive regulation  and supervision
where they  do  business  by  state insurance  commissioners  who  regulate  the
standards of solvency which must be maintained, the nature of and limitations on
investments, reports of financial condition, and requirements regarding reserves
for  unearned premiums, losses  and other matters. A  significant portion of the
assets of insurance companies are required by law to be held in reserve  against
potential claims on policies and is not available to general creditors. Although
the  federal government  does not  regulate the  business of  insurance, federal
initiatives including  pension  regulation,  controls  on  medical  care  costs,
minimum  standards for no-fault automobile insurance, national health insurance,
tax law changes affecting life insurance  companies and repeal of the  antitrust
exemption  for  the insurance  business can  significantly impact  the insurance
business.
 
    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. See the Information
Supplement--for further information concerning insurance.
 
    Because the insurance on the Bonds, if any, 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.
 
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
 
                                       8
<PAGE>
Trustee) plus a sales charge set forth  in "Essential Information" in Part A  of
this  Prospectus, 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. See "UNIT VALUE AND EVALUATION."
 
    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 in the primary or
secondary 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 tables based  on the amount of
intended aggregate  purchases as  expressed  in the  letter  of intent.  Due  to
administrative  limitations and in  order to permit  adequate tracking, the only
secondary market  purchases that  will be  permitted to  be applied  toward  the
intended  specified amount and that will receive the corresponding reduced sales
charge are  those  Units that  are  acquired through  or  from the  Sponsor.  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  the  Trustee pending
completion of these purchases. All distributions on Units held in escrow will be
credited  to  such  Unitholder's  account.  If  total  purchases  prior  to  the
expiration  of the letter of intent period  equal or exceed the amount specified
in a Unitholder's letter of intent, the Units held in escrow will be transferred
to such Unitholder's account.  If the total purchases  are less than the  amount
specified,  the Unitholder involved must pay the  Sponsor an amount equal to the
difference between the amounts  paid for these purchases  and the amounts  which
would  have  been paid  if the  higher sales  charge had  been applied.  If such
Unitholder does  not pay  the additional  amount within  20 days  after  written
request  by  the  Sponsor  or the  Unitholder's  securities  representative, the
Sponsor will  instruct  the Trustee  to  redeem  an appropriate  number  of  the
escrowed Units to meet the required payment. By establishing a letter of intent,
a  Unitholder irrevocably appoints the Sponsor  as attorney to give instructions
to redeem any or  all of such  Unitholder's escrowed Units,  with full power  of
substitution in the premises. A Unitholder or his securities representative must
notify  the Sponsor whenever such  Unitholder makes a purchase  of Units that he
wishes to  be counted  towards the  intended amount.  Sales charges  during  the
primary offering period are as follows:

*Breakpoint  sales charges are computed both on  a dollar basis and on the basis
 of the number of Units purchased, using the equivalent of 500 Units to $50,000,

    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. See "UNIT VALUE AND EVALUATION."  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. 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:

    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).  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.
 
    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.
 
    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.
 
    Accrued interest from the preceding Record  Date to, but not including,  the
settlement  date of the transaction (three business days after purchase) will be
added to the Public Offering Price to determine the purchase price of Units. See
"WHAT IS ACCRUED INTEREST?".
 
    The graduated sales  charges set forth  above 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  ("immediate family members") 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 "HOW
UNITS OF  THE TRUSTS  ARE DISTRIBUTED  TO  THE PUBLIC?")  by (1)  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, (2) 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, (3) any person who for at least 90 days, has been an  officer,
director  or bona fide employee of any firm offering Units for sale to investors
or their  immediate family  members  (as defined  above)  and (4)  officers  and
directors  of  bank  holding companies  that  make Units  available  directly or
through  subsidiaries  or  bank  affiliates.  Notwithstanding  anything  to  the
contrary  in  this  Prospectus,  such investors,  bank  trust  departments, firm
employees and bank  holding company  officers and directors  who purchase  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 between 1/2% to 2% more than the BID
prices of such  Bonds. 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 "UNIT  VALUE
AND EVALUATION.")
 
MARKET FOR UNITS
 
During  the  initial public  offering period,  the Sponsor  intends to  offer to
purchase Units of each  Trust at a  price equivalent to the  pro rata share  per
Unit  of the OFFERING prices of the Bonds in such Trust (plus accrued interest).
Afterward, although  it  is not  obligated  to do  so,  the Sponsor  intends  to
maintain  a secondary  market for  Units of  each Trust  at its  own expense and
continuously to offer  to purchase  Units of each  Trust at  prices, subject  to
change  at  any time,  which  are based  upon  the BID  prices  of Bonds  in the
respective portfolios of the  Trusts. UNITHOLDERS WHO WISH  TO DISPOSE OF  THEIR
UNITS SHOULD INQUIRE OF THE TRUSTEE OR THEIR BROKER AS TO THE CURRENT REDEMPTION
PRICE. (See "HOW UNITS MAY BE REDEEMED WITHOUT CHARGE?".) 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 (three business days after purchase) as the Trustee
can  complete  the mechanics  of registration,  normally  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 "HOW UNITS MAY BE REDEEMED WITHOUT CHARGE?".)
 
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.  Accrued
interest  does not  include accrual  of original  issue discount  on zero coupon
bonds, Stripped Obligations  or other  original issue  discount bonds.  Interest
accrues  to the  benefit of Unitholders  commencing with the  settlement date of
their purchase transaction.
 
    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, the amount
of accrued interest  to be  added to  the Public  Offering Price  of Units  will
include  only accrued interest from  the Date of Deposit  to, but not including,
the date of  settlement of the  investor's purchase (three  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 Part A of this Prospectus  and
"WHEN ARE DISTRIBUTIONS MADE TO UNITHOLDERS?".) As Bonds mature, or are redeemed
or  sold,  the  accrued  interest  applicable to  such  bonds  is  collected and
subsequently distributed to Unitholders. Unitholders who
 
                                       11
<PAGE>
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 third
business day following the date of sale or tender.
 
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  expected  to be  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  of  any premium  over,  or discount  from,  the par  (maturity) value
inherent in the bond's purchase price. In the calculation of 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. This weighted  average yield is  then
adjusted  to  reflect estimated  expenses, is  compounded, and  is reduced  by a
factor which represents the amortization of  the sales charge over the  expected
average  life of the Trust. 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
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 "OTHER INFORMATION."
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. 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.
 
    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" appearing
in Part A  of this  Prospectus, "COMPOSITION  OF TRUSTS"  and "WHAT  IS THE  TAX
STATUS OF UNITHOLDERS?")
 
    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  a
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 Trusts  are
described more fully elsewhere in the Prospectus.
 
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  division of  J. J.  Kenny Co.,  Inc., 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, a  division of J. J.  Kenny Co., Inc., evaluated
the Bonds as so insured. (See "WHY AND HOW ARE THE BONDS INSURED?".)
 
                                       12
<PAGE>
    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 Part  A of  this Prospectus.)  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.
 
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 Part
A of this Prospectus. 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.  If  the
interest  on a Bond should be determined to be taxable, the Bond would generally
have to  be sold  at a  substantial discount.  In addition,  investors could  be
required  to pay  income tax  on interest  received prior  to the  date of which
interest is determined to be taxable.
 
    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 tax-exempt 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. 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.
 
    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
 
                                       13
<PAGE>
        have  been so excludable if paid by the respective issuer provided that,
        at the  time such  policies are  purchased, the  amounts paid  for  such
        policies  are reasonable,  customary and consistent  with the reasonable
        expectation that the issuer of the bonds, rather than the insurer,  will
        pay  debt  service  on  the  bonds. Paragraph  (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 Part A of this Prospectus.
 
    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 Internal Revenue Code provides that interest on indebtedness incurred or
continued  to purchase  or carry  obligations, the  interest on  which is wholly
exempt from Federal income taxes, is not deductible. Because each Unitholder  is
treated  for Federal income tax purposes as the owner of a pro rata share of the
Bonds owned by the applicable Trust, interest on borrowed funds used to purchase
or carry Units  of such  Trust will  not be  deductible for  Federal income  tax
purposes.  Under rules used by the Internal Revenue Service for determining when
borrowed funds are  considered used for  the purpose of  purchasing or  carrying
particular  assets, the purchase  of Units may  be considered to  have been made
with borrowed funds even though the borrowed funds are not directly traceable to
the purchase of Units (however, these  rules generally do not apply to  interest
paid  on indebtedness  incurred to  purchase or  improve a  personal residence).
Similar rules are  generally applicable  for state tax  purposes. Special  rules
apply  in  the  case  of  certain  financial  institutions  that  acquire Units.
Investors with questions regarding  these issues should  consult with their  tax
advisers.
 
    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.
 
    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 PART  A OF THIS  PROSPECTUS, 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.
 
WHAT ARE NORMAL TRUST OPERATING EXPENSES?
 
No  annual advisory  fee is charged  to the  Trusts by the  Sponsor. The Sponsor
does, however, receive a fee as set  forth in "Essential Information" in Part  A
of  this  Prospectus  for regularly  evaluating  the Bonds  and  for maintaining
surveillance over the portfolio. (See "UNIT VALUE AND EVALUATION.")
 
    The Trustee receives for ordinary recurring services an annual fee for  each
plan  of distribution  for each  Trust as  set forth  in "Essential Information"
appearing in Part A of this Prospectus. 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 of  Shelter" 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.
 
                                       14
<PAGE>
    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.
 
    All or  a portion  of  the expenses  incurred  in establishing  the  Trusts,
including costs of preparing the registration statement, the trust indenture and
other  closing  documents, registering  Units with  the Securities  and Exchange
Commission and states, the  initial audit of each  Trust portfolio, legal  fees,
the  initial  fees  and  expenses  of the  Trustee  and  any  other non-material
out-of-pocket expenses, will be paid by the Trusts and amortized over the  first
five  years of such Trusts. The following  are additional 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.
 
WHEN ARE DISTRIBUTIONS MADE TO UNITHOLDERS?
 
Interest received by the Trustee on the Bonds in each Trust, including that part
of the proceeds of  any disposition of Bonds  which represents accrued  interest
and  including  any insurance  proceeds representing  interest due  on defaulted
Bonds, shall be credited to the "Interest  Account" of such Trust and all  other
moneys  received by the Trustee shall be  credited to the "Principal Account" of
such Trust.
 
    The pro rata share of  cash in the Principal Account  in each Trust will  be
computed as of each semi-annual Record Date and distributions to the Unitholders
as of such Record Date will be made on or shortly after the fifteenth day of the
month. Proceeds received from the disposition, including sale, call or maturity,
of  any of the Bonds and all amounts  paid with respect to zero coupon bonds and
Stripped Obligations will be  held in the Principal  Account and either used  to
pay  for Units  redeemed or distributed  on the Distribution  Date following the
next semi-annual Record Date. The Trustee is not required to make a distribution
from the  Principal  Account  of  any Trust  unless  the  amount  available  for
distribution in such account equals at least ten cents per Unit.
 
    The pro rata share of the Interest Account in each Trust will be computed by
the  Trustee each month as of each Record Date and distributions will be made on
or shortly after the fifteenth day of the month to Unitholders of such Trust  as
of the Record Date who are entitled to distributions at that time under the plan
of  distribution chosen. Persons who purchase Units  between a Record Date and a
Distribution Date will receive their first distribution on the Distribution Date
following the next Record Date under the applicable plan of distribution.
 
    Purchasers of  Units  who desire  to  receive interest  distributions  on  a
monthly or quarterly basis may elect to do so at the time of purchase during the
initial  public offering  period. Those indicating  no choice will  be deemed to
have chosen the  semi-annual distribution  plan. All  Unitholders, however,  who
purchase  Units during the initial  public offering period and  who hold them of
record on the first Record Date will receive the first distribution of interest.
Thereafter, Record Dates for monthly distributions will be the first day of each
month; Record  Dates  for quarterly  distributions  will  be the  first  day  of
February,   May,  August  and   November;  and  Record   Dates  for  semi-annual
distributions will be  the first day  of May and  November. See Part  A of  this
Prospectus for details of distributions per Unit of each Trust under the various
plans  based upon estimated Net  Annual Interest Income at  the Date of Deposit.
The amount of  the regular distributions  will generally change  when Bonds  are
redeemed, mature or are sold or when fees and expenses increase or decrease. 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  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
 
                                       15
<PAGE>
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
"OWNERSHIP AND TRANSFER OF UNITS.")
 
    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. In addition, 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.
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.
 
ACCUMULATION PLAN
 
The  Sponsor  is  also  the  principal  underwriter  of  the  Accumulation Funds
described  in  the  following  table.  Each  of  these  funds  is  an  open-end,
diversified  management investment company into  which Unitholders may choose to
reinvest  Trust   distributions  automatically,   without  any   sales   charge.
(Reinvestment  generally 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. For a
more detailed description,  Unitholders of  each Accumulation  Fund should  read
carefully  the prospectus of the Accumulation Fund in which they are interested.
For additional information concerning the Accumulation Plan see the  Information
Supplement of this Prospectus.

Shareholder  Services, Inc.  will mail to  each participant  in the Accumulation

                                       16
<PAGE>
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.
 
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, if any, and 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.
 
UNIT VALUE AND EVALUATION
 
The  value of each  Trust is determined by  the Sponsor on the  basis of (1) the
cash on hand in the Trust or moneys  in the process of being collected, (2)  the
value  of the Bonds in  the Trust based on  the BID prices of  the Bonds and (3)
interest  accrued  thereon   not  subject  to   collection,  LESS  (1)   amounts
representing  taxes or governmental charges payable out of the Trust and (2) the
accrued expenses of the Trust. The result of such computation is divided by  the
number  of Units of such  Trust outstanding as of  the date thereof to determine
the per Unit value ("Unit Value") of  such Trust. The Sponsor may determine  the
value  of the Bonds in each Trust (1) on  the basis of current BID prices of the
Bonds obtained from dealers or brokers who customarily deal in bonds  comparable
to  those held by the Trust, (2) if bid  prices are not available for any of the
Bonds, on the basis of bid prices for comparable bonds, (3) by causing the value
of the Bonds to be determined by  others engaged in the practice of  evaluating,
quoting  or appraising comparable bonds or (4)  by any combination of the above.
Although the Unit Value of each Trust is  based on the BID prices of the  Bonds,
the Units are sold initially to the public at the Public Offering Price based on
the OFFERING prices of the Bonds.
 
    Because  the insurance obtained  by the Sponsor  or by the  issuers of Bonds
with respect to  the Bonds in  the Insured  Trusts and with  respect to  insured
Bonds  in Traditional Trusts is effective so long as such Bonds are outstanding,
such insurance will be  taken into account in  determining the bid and  offering
prices  of such  Bonds and therefore  some value attributable  to such insurance
will be included in the value of Units of Trusts that include such Bonds.
 
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 of  the United  States  of
America,  and Units  of State Trusts  only in the  state for which  the Trust is
named and selected other states.
 
                                       17

    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. 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.
 
    The Sponsor plans to allow a  discount to brokers and dealers in  connection
with   the  primary  distribution   of  Units  and   also  in  secondary  market
transactions. The primary market discounts are as follows:

*Breakpoint sales charges and related dealer concessions are computed both on  a
 dollar  basis and  on the  basis of  the number  of Units  purchased, using the
 equivalent of 500 Units to  $50,000, 2,500 Units to  $250,000 etc. and will  be
 applied on that basis which is more favorable to the purchaser.
 
    The  Sponsor currently intends  to maintain a secondary  market for Units of
each Trust.  See "MARKET  FOR UNITS."  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 "HOW IS THE PUBLIC OFFERING PRICE DETERMINED?",
and adjusted to reflect  the cash position of  the Trust principal account,  and
will vary with the size of the purchase as shown in the following table:

  equivalent of 500 Units to $50,000, 2,500 Units to $250,000, etc., and will be

    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 "HOW IS THE PUBLIC OFFERING PRICE DETERMINED?").
 
    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
 
                                       18
<PAGE>
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.
 
OWNERSHIP AND TRANSFER OF UNITS
 
The  ownership of  Units is  evidenced by book  entry positions  recorded on the
books and records of the Trustee  unless the Unitholder expressly requests  that
the  purchased Units be evidenced in Certificate form. The Trustee is authorized
to treat as the owner of Units that person who at the time is registered as such
on the books of the Trustee. Any  Unitholder who holds a Certificate may  change
to  book entry ownership by submitting to the Trustee the Certificate along with
a written request that the Units represented by such Certificate be held in book
entry form. Likewise, a Unitholder who holds Units in book entry form may obtain
a Certificate for such  Units by written  request to the  Trustee. Units may  be
held in denominations of one Unit or any multiple or fraction thereof. Fractions
of  Units are computed to three decimal  places. Any Certificates issued will be
numbered serially for identification, and  are issued in fully registered  form,
transferable  only  on the  books of  the Trustee.  Book entry  Unitholders will
receive a Book Entry Position Confirmation reflecting their ownership.
 
   
    For Trusts allowing optional plans  of distribution, 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  address listed on the back cover  of
this  Part B of  the Prospectus, 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.   This
indemnification  must be in the form of an Open Penalty Bond of Indemnification.
The premium for such an indemnity bond may vary, 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.
 
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 address  listed  on  the  back  cover of  this  Part  B  of  the  Prospectus
(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 above, or provide satisfactory indemnity
required  in  connection with  lost, stolen  or  destroyed Certificates  and (3)
payment of applicable governmental charges, if any. Certificates should be  sent
only  by registered or certified mail to minimize the possibility of their being
lost or stolen. (See "OWNERSHIP AND TRANSFER OF UNITS".) 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. The time  a
telephone redemption request is received
 
                                       19
<PAGE>
determines the "date of tender" as discussed below. The redemption proceeds will
be mailed within three business days following the telephone redemption request.
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 third business day following the date of tender, 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 third 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.
Unitholders  should  check with  the Trustee  or their  broker to  determine the
Redemption Price before tendering Units.
 
    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 "HOW BONDS MAY  BE REMOVED FROM  THE TRUSTS.") Units  so redeemed shall  be
cancelled.  To  the  extent that  Bonds  are sold  from  a Trust,  the  size and
diversity of such Trust will  be reduced. Such sales may  be required at a  time
when  Bonds would not  otherwise be sold  and might result  in lower prices than
might otherwise be realized.
 
    The Redemption Price is  determined on the  basis of the  BID prices of  the
Bonds  in each Trust, while  the initial Public Offering  Price of Units will be
determined on the  basis of the  OFFERING prices of  the Bonds as  of 4:00  p.m.
eastern  time on any day on which the  Exchange is normally open for trading and
such determination is made. As of any given time, the difference between the bid
and offering prices  of such  Bonds may  be expected to  average 1/2%  to 2%  of
principal amount. 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 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 a specified percentage 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."
 
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 "HOW UNITS MAY BE REDEEMED WITHOUT
CHARGE.")  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.
 
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 Part A of  this Prospectus and "RISK  FACTORS" for a discussion of
call provisions of portfolio Bonds.
 
                                       20
<PAGE>
    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. 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 "COMPOSITION OF  TRUSTS" 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.
 
INFORMATION ABOUT THE TRUSTEE
 
The Trustee and its address are stated on  the back cover of this Part B of  the
Prospectus. The Trustee is subject to supervision and examination by the Federal
Deposit  Insurance Corporation,  the Board of  Governors of  the Federal Reserve
System and either the Comptroller of the Currency or state banking authorities.
 
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.
 
INFORMATION ABOUT THE SPONSOR
 
John Nuveen & Co. Incorporated, the Sponsor and Underwriter, was founded in 1898
and  is  the oldest  and  largest investment  banking  firm specializing  in the
underwriting and distribution of tax-exempt securities and maintains the largest
research department in the investment  banking community devoted exclusively  to
the  analysis of municipal securities. In  1961 the Sponsor began sponsoring the
Nuveen Tax-Exempt Unit Trust and, since this  time, it has issued more than  $30
billion  in tax-exempt unit trusts, including over $8 billion in insured trusts.
The Sponsor is also principal underwriter  of 16 mutual funds and 60  closed-end
funds.  These registered open-end and  closed-end investment companies currently
have approximately  $32.8 billion  in  tax-exempt securities  under  management.
Nationwide, more than 1,000,000 individual investors have purchased Nuveen's tax
exempt  trusts and  funds. The  present corporation was  organized in  1967 as a
wholly-owned subsidiary of  Nuveen Corporation, successor  to the original  John
Nuveen  & Co. founded in 1898 as a sole proprietorship and incorporated in 1953.
In 1974, John Nuveen & Co. Incorporated became a wholly-owned subsidiary of  The
St. Paul Companies, Inc., a financial services management company located in St.
Paul,  Minnesota. On May 19, 1992,  common shares comprising a minority interest
in The John Nuveen  Company ("JNC"), a newly  organized corporation which  holds
all  of the  shares of  Nuveen, were sold  to the  general public  in an initial
public offering. St. Paul retains a controlling interest in JNC with over 70% of
JNC's shares. The Sponsor is a member of the National Association of  Securities
Dealers,  Inc. and  the Securities  Industry Association  and has  its principal
offices located in Chicago (333 W. Wacker Drive) and New York (Swiss Bank Tower,
10 East 50th Street). It maintains 14 regional offices.
 
    To help advisers and investors better understand and more efficiently use an
investment in  the  Trust to  reach  their  investment goals,  the  Sponsor  may
advertise and create specific investment programs and systems. For example, such
activities may include presenting information on how to use an investment in the
Trust,  alone or in combination with an investment in other mutual funds or unit
investment trusts sponsored by Nuveen, to accumulate assets for future education
needs or periodic payments such as  insurance premiums. The Trust's sponsor  may
produce  software or  additional sales literature  to promote  the advantages of
using the Trust to meet these and other specific investor needs.
 
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 "COMPOSITION OF TRUSTS" 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" appearing in Part A of this Prospectus.)
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
 
                                       22
<PAGE>
registration  books of the Trust maintained  by the Trustee. Within a reasonable
time thereafter the Trustee shall liquidate any Bonds in the Trust then held and
shall deduct  from  the assets  of  the Trust  any  accrued costs,  expenses  or
indemnities  provided  by  the  Indenture which  are  allocable  to  such Trust,
including estimated compensation of the Trustee and costs of liquidation and any
amounts required as a reserve to provide for payment of any applicable taxes  or
other  governmental charges. The Trustee shall then distribute to Unitholders of
such Trust their pro  rata share of  the balance of  the Interest and  Principal
Accounts.  With such  distribution the  Unitholders shall  be furnished  a final
distribution  statement,  in   substantially  the  same   form  as  the   annual
distribution statement, of the amount distributable. At such time as the Trustee
in  its sole discretion shall determine that  any amounts held in reserve are no
longer necessary, it shall make distribution thereof to Unitholders in the  same
manner.

GENERAL RISK DISCLOSURE
 
    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 in Part A  of this Prospectus, 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 "Risk 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  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
 
                                       2
<PAGE>
redemption price of such issues may be  more or less than the offering price  of
such  bonds. Additionally,  unusually high  rates of  default on  the underlying
mortgage loans may reduce revenues available for the payment of principal of  or
interest  on such mortgage  revenue bonds. Single  family mortgage revenue bonds
issued after December 31,  1980 were issued under  Section 103A of the  Internal
Revenue Code of 1954, as amended, or Section 143 of the Internal Revenue Code of
1986,  which Sections  contain certain requirements  relating to the  use of the
proceeds of such bonds  in order for  the interest on such  bonds to retain  its
tax-exempt  status. In  each case,  the issuer  of the  bonds has  covenanted to
comply with applicable requirements and bond  counsel to such issuer has  issued
an  opinion that  the interest on  the bonds  is exempt from  Federal income tax
under existing  laws  and regulations.  There  can  be no  assurance  that  such
continuing requirements will be satisfied; the failure to meet such requirements
could  cause interest  on the  Bonds to be  subject to  Federal income taxation,
possibly from the date of issuance of the Bonds.
 
    FEDERALLY ENHANCED  OBLIGATIONS.   Some of  the mortgages  which secure  the
various  health care or housing projects which underlie the previously discussed
Health Facility, Housing,  and Single Family  Mortgage Revenue Obligations  (the
"Obligations")  in a Trust may be  insured by the Federal Housing Administration
("FHA"). Under FHA  regulations, the  maximum insurable  mortgage amount  cannot
exceed  90%  of the  FHA's  estimated value  of  the project.  The  FHA mortgage
insurance does not constitute a guarantee of timely payment of the principal  of
and  interest on the Obligations. Payment  of mortgage insurance benefits may be
(1) less than the principal amount of Obligations outstanding or (2) delayed  if
disputes  arise as to  the amount of the  payment or if  certain notices are not
given to the FHA within  the prescribed time periods.  In addition, some of  the
previously  discussed Obligations may be secured by mortgage-backed certificates
guaranteed by the  Government National Mortgage  Association ("GNMA"), a  wholly
owned  corporate  instrumentality  of  the  United  States,  and/or  the Federal
National  Mortgage  Association  ("Fannie   Mae")  a  federally  chartered   and
stockholder-owed  corporation. GNMA and  Fannie Mae guarantee  timely payment of
principal and  interest  on the  mortgage-backed  certificates, even  where  the
underlying   mortgage  payments   are  not  made.   While  such  mortgage-backed
certificates are often pledged  to secure payment of  principal and interest  on
the  Obligations, timely payment of interest and principal on the Obligations is
not insured or guaranteed by  the United States, GNMA,  Fannie Mae or any  other
governmental  agency or  instrumentality. The  GNMA mortgage-backed certificates
constitute a general obligation  of the United States  backed by its full  faith
and  credit. The obligations of Fannie  Mae, including its obligations under the
Fannie Mae mortgage-backed securities, are obligations solely of Fannie Mae  and
are  not backed  by, or  entitled to, the  full faith  and credit  of the United
States.
 
    INDUSTRIAL REVENUE OBLIGATIONS.   Certain  of the Bonds  in a  Trust may  be
industrial  revenue bonds  ("IRBs"), including pollution  control revenue bonds,
which  are  tax-exempt  securities  issued  by  states,  municipalities,  public
authorities  or similar entities to finance  the cost of acquiring, constructing
or improving various industrial projects. These projects are usually operated by
corporate entities. Issuers are obligated only to pay amounts due on the IRBs to
the extent that funds are available from the unexpended proceeds of the IRBs  or
receipts  or revenues of the issuer under  an arrangement between the issuer and
the corporate operator of  a project. The  arrangement may be in  the form of  a
lease, installment sale agreement, conditional sale agreement or loan agreement,
but  in each case  the payments to the  issuer are designed  to be sufficient to
meet the  payments of  amounts due  on the  IRBs. Regardless  of the  structure,
payment  of IRBs is solely dependent  upon the creditworthiness of the corporate
operator of  the  project and,  if  applicable, corporate  guarantor.  Corporate
operators  or  guarantors may  be affected  by  many factors  which may  have an
adverse impact on  the credit  quality of  the particular  company or  industry.
These include cyclicality of revenues and earnings, regulatory and environmental
restrictions,  litigation  resulting  from  accidents  or environmentally-caused
illnesses, extensive competition  and financial deterioration  resulting from  a
corporate  restructuring pursuant to a leveraged buy-out, takeover or otherwise.
Such a restructuring  may result in  the operator of  a project becoming  highly
leveraged  which may have an impact on such operator's creditworthiness which in
turn would have  an adverse impact  on the  rating and/or market  value of  such
Bonds.  Further, the  possibility of  such a  restructuring may  have an adverse
impact on the market for and consequently  the value of such Bonds, even  though
no actual takeover or other action is ever contemplated or effected. The IRBs in
a  Trust may be subject to  special or extraordinary redemption provisions which
may provide for redemption  at par or,  in the case  of original issue  discount
bonds,  accreted value. The  Sponsor cannot predict the  causes or likelihood of
the redemption of IRBs in a Trust prior to the stated maturity of such Bonds.
 
    ELECTRIC UTILITY  OBLIGATIONS.    Some  of  the Bonds  in  a  Trust  may  be
obligations  of issuers  whose revenues are  primarily derived from  the sale of
electric energy. The problems  faced by such issuers  include the difficulty  in
obtaining  approval for timely  and adequate rate  increases from the applicable
public utility  commissions,  the  difficulty of  financing  large  construction
programs,  increased competition, reductions  in estimates of  future demand for
electricity in certain areas of the  country, the limitations on operations  and
increased costs and delays
 
                                       3
<PAGE>
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  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
 
                                       4
<PAGE>
underlying  property for unpaid  taxes. A third  type of dedicated-tax supported
Bond may be secured by a tax levied upon the manufacture, sale or consumption of
commodities or upon the license to pursue certain occupations or upon  corporate
privileges  within a taxing jurisdiction. As to any of these types of Bonds, the
ability of  the  designated  revenues  to satisfy  the  interest  and  principal
payments  on such  bonds may be  affected by  changes in the  local economy, the
financial success of the  enterprise responsible for the  payment of the  taxes,
the  value of  any property on  which taxes may  be assessed and  the ability to
collect such  taxes in  a timely  fashion. Each  of these  factors will  have  a
different affect on each distinct type of dedicated-tax supported bonds.
 
    MUNICIPAL LEASE BONDS.  Some of the Bonds in a Trust may be obligations that
are  secured  by lease  payments  of a  governmental  entity. Such  payments are
normally subject to  annual budget  appropriations of  the leasing  governmental
entity.  A governmental  entity that enters  into such a  lease agreement cannot
obligate future  governments to  appropriate  for and  make lease  payments  but
covenants  to take such action as is necessary to include any lease payments due
in its budgets and to make the appropriations therefor. A governmental  entity's
failure to appropriate for and to make payments under its lease obligation could
result  in insufficient funds  available for payment  of the obligations secured
thereby.
 
    ORIGINAL ISSUE  DISCOUNT BONDS  AND STRIPPED  OBLIGATIONS.   Certain of  the
Bonds  in a Trust may be original  issue discount bonds. These Bonds were issued
with nominal  interest rates  less than  the rates  then offered  by  comparable
securities  and as a consequence  were originally sold at  a discount from their
face, or par, values. This original  issue discount, the difference between  the
initial  purchase price and face value, is deemed under current law to accrue on
a daily basis and the accrued  portion is treated as tax-exempt interest  income
for  federal income tax purposes. On sale  or redemption, gain, if any, realized
in excess of the earned  portion of original issue  discount will be taxable  as
capital  gain. See "What is the Tax Status of Unitholders". The current value of
an original issue discount bond reflects the present value of its face amount at
maturity. In a stable interest rate environment, the market value of an original
issue discount bond would  tend to increase  more slowly in  early years and  in
greater increments as the bond approached maturity.
 
    Certain  of the original issue discount bonds  in a Trust may be zero coupon
bonds. Zero coupon bonds do not provide for the payment of any current interest;
the buyer receives only the right to receive a final payment of the face  amount
of  the bond at its maturity. The effect of  owning a zero coupon bond is that a
fixed yield is earned not only on  the original investment but also, in  effect,
on  all  discount  earned  during  the life  of  the  obligation.  This implicit
reinvestment of earnings at the same rate eliminates the risk of being unable to
reinvest the income on such obligation at a rate as high as the implicit  yield,
but  at the same time also eliminates the holder's ability to reinvest at higher
rates in  the  future.  For  this  reason, zero  coupon  bonds  are  subject  to
substantially  greater  price  fluctuations during  periods  of  changing market
interest rates  than are  securities  of comparable  quality that  pay  interest
currently.
 
    Original  issue discount bonds, including zero  coupon bonds, may be subject
to redemption at prices  based on the  issue price plus  the amount of  original
issue   discount  accreted  to  redemption   (the  "accreted  value")  plus,  if
applicable, some premium.  Pursuant to  such call provisions  an original  issue
discount  bond may be called prior to its maturity date at a price less than its
face value. See the  "Schedules of Investments" for  more information about  the
call provisions of portfolio Bonds.
 
    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
"WHAT IS THE TAX STATUS OF UNITHOLDERS?" in Part B of this Prospectus.)
 
    Unitholders  should consult their own tax advisers with respect to the state
and local tax consequences of owning  original issue discount bonds or  Stripped
Obligations.  Under applicable  provisions governing determination  of state and
local taxes, interest on original  issue discount bonds or Stripped  Obligations
may  be deemed to  be received in  the year of  accrual even though  there is no
corresponding cash payment.

WHY AND HOW ARE THE BONDS INSURED?
 
INSURANCE ON BONDS
 
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 MBIA  Insurance
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,  the Commonwealth  of Puerto  Rico, the  Commonwealth of  the Northern
Mariana Islands, the Virgin  Islands of the United  States and the Territory  of
Guam. The Insurer has one European branch in the Republic of France.
 
    As  of September 30,  1995 the Insurer  had admitted assets  of $3.7 billion
(unaudited), total liabilities  of $2.5 billion  (unaudited), and total  capital
and  surplus of $1.2 billion (unaudited) determined in accordance with statutory
accounting  practices   prescribed   or  permitted   by   insurance   regulatory
authorities.  As of December 31,  1994, the Insurer had  admitted assets of $3.4
billion (audited),  total  liabilities  of $2.3  billion  (audited),  and  total
capital  and surplus  of $1.1  billion (audited)  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

   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.
 
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  in
Part  A of  this Prospectus  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"), MBIA Insurance 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
 
                                       7
<PAGE>
MBIA). There can be no assurance that any insurer listed therein will be able to
satisfy its commitments  in the event  claims are made  in the future.  However,
Standard  &  Poor's  Corporation has  rated  the claims-paying  ability  of each
insurer "AAA," and Moody's Investors Service has rated all bonds insured by each
such insurer,  except  ConnieLee, "Aaa."  Moody's  Investor's Service  gives  no
ratings for bonds insured by ConnieLee.
 
    Because  any such insurance will  be effective so long  as the insured Bonds
are outstanding, such insurance  will be taken into  account in determining  the
market  value  of  such Bonds  and  therefore  some value  attributable  to such
insurance will be included in the value of the Units of the Trust that  includes
such  Bonds. The insurance does not, however,  guarantee the market value of the
Bonds or of the Units.
 
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 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 Nuveen California
Tax-Free Value 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 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
 
                                       8

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

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  Nuveen Massachusetts  Insured Tax-Free Value  Fund and the  Nuveen New York
Insured Tax-Free  Value  Fund, which  are  each available  for  reinvestment  to
Unitholders.  (The Massachusetts and  New York Portfolios  are available only to
those Unitholders who  are residents  of the state  for which  the portfolio  is
named.) The Insured Bond Fund has the objective of providing, through investment
in  professionally managed  portfolios of  municipal bonds,  as high  a level of
current interest income exempt from both Federal income tax and, in the case  of
designated  state portfolios,  from the income  tax imposed  by each portfolio's
designated state, as  is consistent  with preservation of  capital. The  Insured
Bond  Fund may include in each of its portfolios the same type of investments as
the Tax-Free Bond Fund, each of  which is covered by insurance guaranteeing  the
timely  payment of  principal and  interest or  is backed  by a  deposit of U.S.
Government securities.
 
THE MONEY MARKET FUND
 
    The Money Market Fund  consists of the  Nuveen Massachusetts Tax-Free  Money
Market  Fund and the Nuveen New York  Tax-Free Money Market Fund, which are each

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

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.

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
 
                                       9

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.

2,  all registered closed-end management  investment companies. These registered
open-end and closed-end investment companies currently have approximately  $32.8
billion  in  tax-exempt  securities  under  management.  Nationwide,  more  than
1,000,000 individual investors  have purchased  Nuveen's tax  exempt trusts  and
funds.  The  present  corporation  was  organized  in  1967  as  a  wholly-owned
subsidiary of Nuveen Corporation,  successor to the original  John Nuveen &  Co.
founded in 1898 as a sole proprietorship and incorporated in 1953. In 1974, John
Nuveen  &  Co. Incorporated  became a  wholly-owned subsidiary  of The  St. Paul
Companies, Inc., a financial  services management company  located in St.  Paul,
Minnesota.  On May 19, 1992, common shares comprising a minority interest in The
John Nuveen Company ("JNC"),  a newly organized corporation  which holds all  of
the  shares of  Nuveen, were  sold to  the general  public in  an initial public
offering. St. Paul retains a controlling interest in JNC with over 70% of  JNC's
shares.  The  Sponsor is  a  member of  the  National Association  of Securities

    To help advisers and investors better understand and more efficiently use an
investment in the Trust  to reach their investment  goals, the Trust's  sponsor,
John  Nuveen &  Co. Incorporated, may  advertise and  create specific investment
programs and  systems.  For  example, such  activities  may  include  presenting
information  on how to use  an investment in the  Trust, alone or in combination
with an investment in other mutual funds or unit investment trusts sponsored  by
Nuveen,  to accumulate  assets for future  education needs  or periodic payments
such as  insurance  premiums.  The  Trust's  sponsor  may  produce  software  or
additional sales literature to promote the advantages of using the Trust to meet
these and other specific investor needs.
 
    The   Sponsor  offers  a  program   of  advertising  support  to  registered
broker-dealer firms, banks and bank affiliates ("Firms") that sell Trust  Units.
Under  this program, the  Sponsor will pay or  reimburse the Firm  for up to one
half of specified media costs incurred in the placement of advertisements  which
jointly  feature the Firm and the Nuveen Trusts. Reimbursements to the Firm will
be based on the  number of the Firm's  registered representatives who have  sold
Trust Units during the prior calendar year according to an established schedule.
Reimbursements  under this program  will be made  by the Sponsor  and not by the
Trusts.
 
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.
 
                                       11
<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  rating on  the units  of an  insured investment  trust
(hereinafter  referred to  collectively as  "units" and  "trusts") is  a current
assessment of  creditworthiness with  respect  to the  investment held  by  such
trust.  This assessment takes  into consideration the  financial capacity of the
issuers and of any guarantors, insurers,  lessees or mortgagors with respect  to
such investments. The assessment, however, does not take into account the extent
to  which  trust expenses  or  portfolio asset  sales  for less  than  the trust
purchase price  will  reduce payment  to  the  unitholder of  the  interest  and
principal  required to be paid on the  portfolio assets. In addition, the rating
is not a recommendation to purchase, sell or hold units, inasmuch as the  rating
does not comment as to market price of the units or suitability for a particular
investor.
 
    Units rated "AAA" are composed exclusively of assets that are rated "AAA" by
Standard  &  Poor's and/or  certain  short-term investments.  Standard  & Poor's
defines its  AAA  rating for  such  assets as  the  highest rating  assigned  by
Standard  & Poor's  to a  debt obligation.  Capacity to  pay interest  and repay
principal is very strong.  However, unit ratings may  be subject to revision  or
withdrawal  at any time by Standard & Poor's and each rating should be evaluated
independently of any other rating.
 
    MOODY'S INVESTORS  SERVICE, INC.    A brief  description of  the  applicable
Moody's Investors Service, Inc. rating symbols and their meanings follows:
 
    Aaa--Bonds which are rated Aaa are judged to be the best quality. They carry
the  smallest degree of investment  risk and are generally  referred to as "gilt
edge." Interest payments are protected by a large or by an exceptionally  stable
margin and principal is secure. While the various protective elements are likely
to  change, such changes  as can be  visualized are most  unlikely to impair the
fundamentally strong position of such issues. Their safety is so absolute  that,
with  the  occasional  exception  of oversupply  in  a  few  specific instances,
characteristically, their  market  value  is affected  solely  by  money  market
fluctuations.
 
    Aa--Bonds  which  are rated  Aa  are judged  to be  of  high quality  by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are  rated lower than the  best bonds because margins  of
protection  may  not  be  as  large as  in  Aaa  securities  or  fluctuations of
protective elements may be of greater  amplitude or there may be other  elements
present  which  make the  long-term  risks appear  somewhat  larger than  in Aaa
securities. Their  market value  is virtually  immune to  all but  money  market
influences,  with  the  occasional exception  of  oversupply in  a  few specific
instances.
 
    A--Bonds which are rated A possess many favorable investment attributes  and
are  to be considered as upper medium grade obligations. Factors giving security
to principal and interest are considered  adequate, but elements may be  present
which  suggest a susceptibility to impairment sometime in the future. The market
value of A-rated bonds may be influenced to some degree by economic  performance
during  a sustained period of depressed business conditions, but, during periods
of normalcy,  A-rated  bonds  frequently  move  in  parallel  with  Aaa  and  Aa
obligations,  with  the occasional  exception of  oversupply  in a  few specific
instances.
 
    Moody's bond rating  symbols may  contain numerical modifiers  of a  generic
rating  classification. The modifier 1 indicates that the bond ranks at the high
end of  its category;  the modifier  2 indicates  a mid-range  ranking; and  the
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
 
    Baa--Bonds  which are rated Baa are  considered as medium grade obligations,
i.e., they are neither  highly protected nor  poorly secured. Interest  payments
and  principal security appear  adequate for the  present but certain protective
elements may be lacking or may  be characteristically unreliable over any  great
length  of time. Such  bonds lack outstanding  investment characteristics and in
fact have speculative  characteristics as  well. The market  value of  Baa-rated
bonds  is more  sensitive to changes  in economic circumstances,  and aside from
occasional speculative factors applying to some bonds of this class, Baa  market
valuations  move in parallel  with Aaa, Aa  and A obligations  during periods of
economic normalcy, except in instances of oversupply.
 
    Con. (--)--Bonds for which the security depends upon the completion of  some
act  or the  fulfillment of  some condition  are rated  conditionally. These are
bonds secured by (a)  earnings of projects under  construction, (b) earnings  of
projects  unseasoned  in  operation  experience, (c)  rentals  which  begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes  probable credit stature upon  completion
of construction or elimination of basis of condition.
 
                                       12
<PAGE>
    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.
 
HOW THE TRUST COMPARES PERFORMANCE
 
    The Sponsor may compare the estimated returns of the Trust with the  returns
or  yields  of  other  tax-free  and taxable  investments,  often  on  a taxable
equivalent basis. In addition, the Sponsor  from time to time may quote  various
performance  measures and  studies in  order to  compare the  historical returns
available from an investment  in municipal securities  with investments in  both
tax-free and taxable securities.
 
    In  September 1995, Nuveen  Research prepared one  such study which compared
the after-tax value  of $100,000  initially invested  in 1975  in various  asset
classes  including  municipal  bonds,  treasury bonds  and  corporate  bonds. As
indicated in the chart  provided below, the 20-year  study shows that  municipal
bonds  significantly outperformed corporate and  treasury bonds once the effects
of taxes were  factored in.  In fact, over  the 20-year  period, municipal  bond
returns in dollars were more than double those of treasury bonds.

after-tax total returns  of $100,000  initially in 1975  in each  of the  Lehman
Brothers MuniBond Index, Long-Term Treasury Index and Long-Term Corporate Index.
As  indicated in the graph,  such an investment in  the Lehman Brothers MuniBond
Index, Long-Term  Treasury  Index  and  Long-Term  Corporate  Index  would  have
appreciated  to $448,740,  $267,668, and  $304,049, respectively  at the  end of
1994. The  graph  assumes all  proceeds  of  investment are  reinvested  at  the
respective  index rates at the time of reinvestment and also assumes that 20% of
the assets in each category are turned over annually and proceeds are reinvested
in the respective indexes. The tax rates assumed to generate the after-tax total
returns were based upon the income  and capital gain rates applicable each  year
from  1975-1994 for an investor who earned the inflation-adjusted equivalents of
$400,000 in 1994. In addition, treasury returns were "grossed up" an assumed  5%
to  take into account the Treasuries' exemption from state income tax. The graph
is for  illustrative  purposes  only,  and does  not  represent  the  return  or
performance  of any Nuveen  Tax-Free Unit Trust  and is not  intended to predict
future results.

    A comparison  of  the  estimated  returns of  the  Trust  and  the  historic
performance  of  municipal  bonds  to  the  returns  and  performance  of  other
investments is  one  element  to  consider  in  making  an  informed  investment
decision.  Taxable investments have investment  characteristics that differ from
those of the Trust.  U.S. Government bonds are  long-term investments backed  by
the  full faith  and credit of  the U.S.  Government and are  subject to federal
income tax  but are  exempt from  state  income taxes.  Bank CDs  are  generally
short-term  FDIC insured investments, which pay fixed principal and interest but
are subject to fluctuating rollover rates. Both bank CDs and corporate bonds are
generally subject to both federal and state income taxes. Money market funds are
short term  investments with  stable net  asset values,  fluctuating yields  and
special features that enhance liquidity.

                            MASSACHUSETTS DISCLOSURE
 
ECONOMIC FACTORS--MASSACHUSETTS
 
    Without  intending  to be  complete,  the following  briefly  summarizes the
current financial situation, as  well as some of  the complex factors  affecting
the   financial   situation,   in  the   Commonwealth   of   Massachusetts  (the
"COMMONWEALTH"). It  is derived  from sources  that are  generally available  to
investors  and is based in part on information obtained from various agencies in
Massachusetts. No  independent verification  has been  made of  the accuracy  or
completeness of the following information.
 
    There  can  be no  assurance that  current or  future statewide  or regional
economic difficulties,  and  the  resulting  impact  on  Commonwealth  or  local
governmental  finances generally, will not adversely  affect the market value of
Massachusetts Obligations in the Trust or the ability of particular obligors  to
make timely payments of debt service on (or relating to) those obligations.
 
    Since  1988, there  has been  a significant  slowdown in  the Commonwealth's
economy, as indicated by  a rise in  unemployment, a slowing  of its per  capita
income  growth and declining state revenues.  In fiscal 1991, the Commonwealth's
expenditures for  state  government  programs  exceeded  current  revenues,  and
although fiscal 1992, 1993 and 1994 revenues exceeded expenditures, no assurance
can be given that lower than expected tax revenues will not resume and continue.
 
    1996  FISCAL  YEAR  BUDGET.   On  June  21, 1995,  the  Governor  signed the
Commonwealth's budget for  fiscal 1996. The  fiscal 1996 budget  is based on  an
estimated  budgeted revenues and other sources of approximately $16.802 billion,
which includes  tax  revenue  estimates of  approximately  $11.654  billion,  an
increase  of  approximately  $475 million,  as  compared to  estimated  1995 tax
revenues of $11.179 billion. The  fiscal 1996 budgeted expenditures are  $16.820
billion,  which  represents  an  approximately 2.6%  increase  from  fiscal 1995
expenditures.
 
    1995 FISCAL  YEAR  BUDGET.   On  July  10,  1994, the  Governor  signed  the
Commonwealth's  budget  for fiscal  1995.  The fiscal  1995  budget is  based on
estimated budgeted revenues and other sources of approximately $16.360  billion,
which  includes revised tax revenue  estimates of approximately $11.179 billion.
Tax revenues for  fiscal 1995 were  originally estimated at  $11.328 billion  in
May,  1994, however,  due to the  slowing of the  rate of growth  in certain tax
revenue  categories  in  the  months  following  the  signing  of  the   budget,
particularly  income tax, the  Secretary of the  Administration on September 26,
1994, as required by law,  reduced the fiscal 1995  tax revenue estimate by  $75
million.  On  January 25,  1995, the  Secretary  for Administration  and Finance
further revised  the fiscal  1995 tax  revenue estimate  to $11.179  billion,  a
reduction of approximately $55 million from the September 26, 1994 estimate. The
tax  revenue estimate includes $19.3 million of  tax cuts signed by the Governor
in the fiscal 1995 budget. Estimated fiscal 1995 tax revenues are  approximately
$572 million higher than fiscal 1994 tax revenues of $10.607 billion.
 
    As  signed  by the  Governor,  the budget  authorizes  approximately $16.482
billion in fiscal  1995 expenditures.  The Governor exercised  his authority  to
veto  and  reduce  individual  line  items  and  reduced  total  expenditures by
approximately $298.2 million and vetoed  certain other law changes contained  in
the fiscal 1995 budget. The $16.449 billion of fiscal 1995 expenditures includes
a  reserve  against  certain  contingencies currently  in  the  amount  of $98.6
million. On January 25,  1995, the Governor  filed a supplemental  appropriation
recommendation  aggregating approximately $43.6  million, which expenditures are
included in the $98.6 million contingency reserve for fiscal 1995  expenditures.
Included in the approximately $298.2 million of vetoes noted above, the Governor
vetoed  approximately $296.9 million in  appropriations for the Executive Office
of Human  Services  and  the  Department of  Public  Welfare,  representing  the
estimate,  at the  time, of  4 months of  funding for  the Commonwealth's public
assistance programs.
 
    On February 10, 1995,  the Governor signed into  law certain reforms to  the
Commonwealth's  program  for Aid  to Families  with Dependent  Children ("AFDC")
which take  effect on  July 1,  1995,  subject to  federal approval  of  certain
waivers.  The revised program reduces AFDC benefits to able bodied recipients by
2.75%, while  allowing them  to keep  a larger  portion of  their earned  wages,
requires  approximately 22,000  able-bodied parents  of school-aged  children to
work  or  perform  community  service  for  20  hours  per  week  and   requires
approximately  16,000 recipients who  have children between the  ages of two and
six to participate  in an  education or  training program  or perform  community
service.  The plan also establishes a pilot program for up to 2,000 participants
that offers  tax  credits and  wage  subsidies  to employers  who  hire  welfare
recipients.  Parents who find employment will  be provided with extended medical
benefits and day care benefits  for up to one  year. The plan mandates  paternal
identification, expands funding for anti-fraud initiatives, and requires parents
on  AFDC to  immunize their  children. Parents  who are  disabled, caring  for a
disabled child, have a child under the  age of two, or are teen-agers living  at
home  and attending high school, will continue to receive cash assistance. Since
most provisions of the
 
                                      B-1
<PAGE>
new law  do  not take  effect  until July  1,  1995, the  Executive  Office  for
Administration  projects that the reforms will not materially affect fiscal 1995
public assistance  spending. The  fiscal 1995  expenditure estimate  of  $16.449
billion  includes $247.8 million appropriated  to fund the Commonwealth's public
assistance programs for the last four months of fiscal 1995. The Commonwealth is
currently evaluating the new law's impact on fiscal 1996 projected spending  for
public assistance programs.
 
    The  fiscal 1995 budget is based  on numerous spending and revenue estimates
the achievement of which cannot be assured.
 
    On November 8, 1994, the voters  in the statewide general election  approved
an  initiative petition that would slightly increase the portion of the gasoline
tax revenue credited to the Highway Fund, one of the Commonwealth's three  major
budgetary  funds, prohibit the transfer of money  from the Highway Fund to other
funds for non-highway purposes and not permit including the Highway Fund balance
in the  computation "consolidated  net surplus"  for purposes  of state  finance
laws.  The initiative petition also  provides that no more  than 15% of gasoline
tax revenues may be used for mass transportation purposes, such as  expenditures
related  to the  Massachusetts Bay  Transit Authority.  The Executive  Office of
Administration and  Finance is  analyzing the  effect, if  any, this  initiative
petition,  which became  law on December  8, 1994,  may have on  the fiscal 1995
budget and  it currently  does not  expect  it to  have any  materially  adverse
impact.  This is not a  constitutional amendment and is  subject to amendment or
repeal by the  Legislature, which  may also,  notwithstanding the  terms of  the
petition,  appropriate moneys from the Highway Fund in such amounts and for such
purposes as it  determines, subject  only to a  constitutional restriction  that
such moneys be used for highways or mass transit purposes.
 
    1994  FISCAL YEAR.   Fiscal 1994 tax  revenue collections were approximately
$10.607 billion, $87 million below the Department of Revenue's fiscal year  1994
tax  revenue estimate of $10.694 billion and  $677 million above fiscal 1993 tax
revenues of  $9.930  billion. Budgeted  revenues  and other  sources,  including
non-tax  revenues, collected in fiscal  1994 were approximately $15.550 billion.
Total revenues and  other sources  increased by approximately  5.7% from  fiscal
1993  to fiscal 1994 while  tax revenues increased by  6.8% for the same period.
Budgeted expenditures and other uses of funds in fiscal 1994 were  approximately
$15.523  billion,  which is  $826.5 million  or  approximately 5.6%  higher than
fiscal 1993 budgeted expenditures and other uses.
 
    As of June  30, 1994, the  Commonwealth showed a  year-end cash position  of
approximately $757 million, as compared to a projected position of $599 million.
 
    In  June, 1993,  the Legislature  adopted and  the Governor  signed into law
comprehensive  education  reform  legislation.  This  legislation  required   an
increase  in expenditures for education purposes above fiscal 1993 base spending
of $1.288 billion of  approximately $175 million in  fiscal 1994. The  Executive
Office   for  Administration  and  Finance   expects  the  annual  increases  in
expenditures above  the  fiscal 1993  base  spending  of $1.288  billion  to  be
approximately  $396 million in fiscal 1995, $625 million in fiscal 1996 and $868
million in fiscal 1997. Additional annual  increases are also expected in  later
fiscal  years. The fiscal  1995 budget as  signed by the  Governor includes $896
million in appropriations to satisfy this legislation.
 
    1993 FISCAL YEAR.  The  Commonwealth's budgeted expenditures and other  uses
were approximately $14.696 billion in fiscal 1993, which is approximately $1.280
billion  or  9.6% higher  than fiscal  1992 expenditures  and other  uses. Final
fiscal 1993 budgeted expenditures were $23  million lower than the initial  July
1992 estimates of fiscal 1993 budgeted expenditures. Budgeted revenues and other
sources  for fiscal 1993  totalled approximately $14.710  billion, including tax
revenues of  $9.930  billion. Total  revenues  and other  sources  increased  by
approximately 6.9% from fiscal 1992 to fiscal 1993, while tax revenues increased
by  4.7%  for the  same period.  Overall, fiscal  1993 ended  with a  surplus of
revenues and other sources over expenditures and other uses of $13.1 million and
aggregate  ending  fund  balances  in  the  budgeted  operating  funds  of   the
Commonwealth  of  approximately $562.5  million. After  payment  in full  of the
distribution of local aid to the  Commonwealth's cities and towns ("Local  Aid")
and  the retirement of short term debt,  the Commonwealth showed a year end cash
position of approximately $622.2 million, as compared to a projected position of
$485.1 million.
 
    1992 FISCAL YEAR.  The  Commonwealth's budgeted expenditures and other  uses
were approximately $13.4 billion in fiscal 1992, which is $238.7 million or 1.7%
lower  than  fiscal  1991  budgeted  expenditures.  Final  fiscal  1992 budgeted
expenditures were $300  million more  than the  initial July  1991 estimates  of
budgetary  expenditures,  due in  part to  increases  in certain  human services
programs, including an increase of $268.7  million for the Medicaid program  and
$50.0  million  for  mental retardation  consent  decree  requirements. Budgeted
revenues and other sources for fiscal 1992 totalled approximately $13.7  billion
(including  tax revenues of approximately  $9.5 billion), reflecting an increase
of approximately 0.7% from fiscal  1991 to 1992 and an  increase of 5.4% in  tax
revenues  for the same period.  Overall, fiscal 1992 is  estimated to have ended
with an excess of revenues and other sources over expenditures and other uses of
$312.3 million. After  payment in  full of  Local Aid  in the  amount of  $514.0
million  due  on June  30, 1992,  retirement  of the  Commonwealth's outstanding
commercial paper (except
 
                                      B-2
<PAGE>
for approximately  $50 million  of bond  anticipation notes)  and certain  other
short  term  borrowings,  as of  June  30, 1992,  the  end of  fiscal  1992, the
Commonwealth showed a year-end cash  position of approximately $731 million,  as
compared  with the Commonwealth's cash  balance of $182.3 million  at the end of
fiscal 1991.
 
    1991 FISCAL YEAR.  Budgeted expenditures for fiscal 1991 were  approximately
$13.659 billion, as against budgeted revenues and other sources of approximately
$13.634  billion. The Commonwealth  suffered an operating  loss of approximately
$21.2 million. Application of the adjusted  fiscal 1990 fund balances of  $258.3
million resulted in a fiscal 1991 budgetary surplus of $237.1 million. State law
requires  that approximately $59.2 million of the fiscal year ending balances of
$237.1 million be placed in the  Stabilization Fund, a reserve from which  funds
can  be appropriated (i) to make up any difference between actual state revenues
in any fiscal  year in which  actual revenues fall  below the allowable  amount,
(ii)  to replace state and local losses by federal funds or (iii) for any event,
as determined by the legislature, which threatens the health, safety or  welfare
of  the  people  or the  fiscal  stability of  the  Commonwealth or  any  of its
political subdivisions.
 
    Upon taking office in  January 1991, the new  Governor proposed a series  of
legislative  and  administrative  actions, including  withholding  of allotments
under Section 9C of Chapter  29 of the General  Laws, intended to eliminate  the
projected  deficits.  The new  Governor's  review of  the  Commonwealth's budget
indicated projected spending  of approximately $14.1  billion with an  estimated
$850  million in  budget balancing  measures that would  be needed  prior to the
close of  fiscal 1991.  At that  time, estimated  tax revenues  were revised  to
approximately $8.8 billion, $903 million less than was estimated at the time the
fiscal  1991  budget  was  adopted.  The Legislature  adopted  a  number  of the
Governor's recommendations and the Governor took certain administrative  actions
not  requiring legislative approval, including the  adoption of a state employee
furlough program. It is estimated  by the Commonwealth that spending  reductions
achieved  through  savings  initiatives  and  withholding  of  allotments  total
approximately $484.3  million  in  aggregate for  fiscal  1991.  However,  these
savings and reductions may be impacted negatively by litigation pursued by third
parties  concerning the Governor's actions under Section 9C of Chapter 29 of the
General Laws and with regard to the state employee furlough program.
 
    In addition, the new  administration in May 1991  filed an amendment to  its
Medicaid  state  plan that  enables  it to  claim  50% federal  reimbursement on
uncompensated care  payments for  certain hospitals  in the  Commonwealth. As  a
result, in fiscal 1991, the Commonwealth obtained additional non-tax revenues in
the  form  of  federal reimbursements  equal  to approximately  $513  million on
account of uncompensated care payments. This reimbursement claim was based  upon
recent  amendments of federal law contained in the Omnibus Budget Reconciliation
Act  of  1990  and,  consequently,  on  relatively  undeveloped  federal   laws,
regulations  and guidelines. At the request of the federal Health Care Financing
Administration, the Office of Inspector General of the United States  Department
of  Health and Human Services  has commenced an audit  of the reimbursement. The
administration, which had  reviewed the  matter with the  Health Care  Financing
Administration   prior  to   claiming  the  reimbursement,   believes  that  the
Commonwealth will prevail in  the audit. If the  Commonwealth does not  prevail,
the  Commonwealth  would have  the  right to  contest  an appeal,  but  could be
required to pay all or part of Medicaid reimbursements with interest and to have
such amount deducted from future reimbursement payments.
 
    1990 AND  1989 FISCAL  YEARS.   In  July 1989,  the former  Governor  vetoed
certain provisions included in the budget legislation for fiscal 1990, including
approximately  $273 million  of the  fiscal 1990  appropriations, including $100
million for Local Aid. One of the Governor's vetoes occasioned a default by  the
Commonwealth  on  a September  1,  1989 payment  of  $2.5 million  on  a general
obligation  contract  with  the  Massachusetts  Community  Development   Finance
Corporation  to which its full faith and  credit had been pledged, which payment
was made on September 17, 1990  after a supplemental appropriation was  proposed
by  the Governor  and passed  by the  legislature. The  legislature overrode the
Governor's veto of  $100 million of  Local Aid and  the Governor then  indicated
that he was withholding the allotment for such expenditure. The Supreme Judicial
Court  invalidated the  Governor's withholding  of $210  million of appropriated
funds for certain Local Aid purposes in May 1990.
 
    Budgeted expenditures for fiscal 1989 and 1990 totalled approximately  $12.6
billion  and $13.3 billion, respectively. Budgeted  revenues for fiscal 1989 and
1990 totalled approximately $12.0 billion and $12.0 billion, respectively.
 
    EMPLOYMENT.  Reversing  a trend  of relatively low  unemployment during  the
early  and mid  1980's, the  Massachusetts unemployment  rate beginning  in 1990
increased significantly to where  the Commonwealth's unemployment rate  exceeded
the national unemployment rate. During 1990, the Massachusetts unemployment rate
increased  from 4.5% in January to 6.1% in  July to 6.7% in August. During 1991,
the Massachusetts  unemployment  rate averaged  9.0%  while the  average  United
States  unemployment rate was  6.7%. The Massachusetts  unemployment rate during
1992 averaged 8.5% while the average  United States unemployment rate was  7.4%.
Since  1993, the  average monthly unemployment  rate has  declined steadily. The
Massachusetts unemployment rate in December 1994 was 5.7%, as compared with  the
United States unemployment rate of 5.4% for the
 
                                      B-3
<PAGE>
same  period. Other  factors which  may significantly  and adversely  affect the
employment rate in  the oCmmonwealth  include reductions  in federal  government
spending  on defense-related industries.  Due to this  and other considerations,
there can  be no  assurances  that unemployment  in  the Commonwealth  will  not
increase in the future.
 
    DEBT  RATINGS.   S&P  currently rates  the Commonwealth's  uninsured general
obligation bonds at A+. At the same  time, S&P currently rates state and  agency
notes  at SP1. From 1989 through 1992, the Commonwealth had experienced a steady
decline in its  S&P rating, with  its decline  beginning in May  1989, when  S&P
lowered  its rating  on the  Commonwealth's general  obligation bonds  and other
Commonwealth obligations  from AA+  to AA  and continuing  a series  of  further
reductions until March 1992, when the rating was affirmed at BBB.
 
    Moody's  currently  rates  the Commonwealth's  uninsured  general obligation
bonds at A1. From 1989 through  1992, the Commonwealth had experienced a  steady
decline  in its rating by  Moody's since May 1989.  In May 1989, Moody's lowered
its rating on the Commonwealth's  notes from MIG-1 to  MIG-2, and its rating  on
the  Commonwealth's commercial paper from  P-1 to P-2. On  June 21, 1989 Moody's
reduced the Commonwealth's general obligation rating  from Aa to A. On  November
15,  1989, Moody's reduced the rating  on the Commonwealth's general obligations
from A  to Baa1,  and  on March  9,  1990, Moody's  reduced  the rating  of  the
Commonwealth's  general  obligation bonds  from  Baa1 to  Baa.  There can  be no
assurance that these ratings will continue.
 
    In recent  years, the  Commonwealth and  certain of  its public  bodies  and
municipalities have faced serious financial difficulties which have affected the
credit  standing  and borrowing  abilities of  Massachusetts and  its respective
entities and may have contributed to higher interest rates on debt  obligations.
The continuation of, or an increase in, such financial difficulties could result
in  declines  in  the market  values  of,  or default  on,  existing obligations
including Massachusetts Obligations  in the  Trust. Should there  be during  the
term  of  the Trust  a financial  crisis relating  to Massachusetts,  its public
bodies or municipalities, the market value and marketability of all  outstanding
bonds  issued by the  Commonwealth and its  public authorities or municipalities
including the Massachusetts Obligations in the Trust and interest income to  the
Trust could be adversely affected.
 
    TOTAL  BOND  AND  NOTE  LIABILITIES.    The  total  general  obligation bond
indebtedness of the Commonwealth (including  Fiscal Recovery Bonds) as of  April
1,   1995  was   approximately  $9.6   billion.  There   were  also  outstanding
approximately $245  million in  general obligation  notes and  other short  term
general obligation debt. The total bond and note liabilities of the Commonwealth
as  of April 1, 1995, including  guaranteed bond and contingent liabilities, was
approximately $12.9 billion.
 
    DEBT SERVICE.    During  the  1980s,  capital  expenditures  were  increased
substantially,  which  has had  a short  term impact  on the  cash needs  of the
Commonwealth and also  accounts for a  significant rise in  debt service  during
that  period. Payments for debt service on Commonwealth general obligation bonds
and notes have risen at an average  annual rate of 22.2% from $770.9 million  in
fiscal 1990 to an estimated $942.3 million in fiscal 1991. Debt service payments
in  fiscal  1992 were  $898.3  million. Debt  service  payments for  fiscal 1992
reflect a $261 million one-time reduction  achieved as a result of the  issuance
of  the refunding bonds in September and October 1991. Debt service expenditures
were approximately $1.140 billion and $1.149  billion for fiscal 1993 and  1994,
respectively,  and are projected  to be approximately  $1.241 billion for fiscal
1995. The fiscal 1993 and fiscal 1994 debt service expenditures reflect  savings
of  $62.9 million and $57.3 million, respectively, achieved through the issuance
of refunding bonds in October 1992, and March, May and August 1993. The  amounts
represented  do not include debt  service on notes issued  to finance the fiscal
1989 deficit  and certain  Medicaid related  liabilities, certain  debt  service
contract  assistance to  the Massachusetts Bay  Transportation Authority ($181.9
million projected in fiscal 1995), the Massachusetts Convention Center Authority
($24.6 million projected in fiscal 1995), the Massachusetts Government Land Bank
($6.0 million projected in  fiscal 1995) and  the Massachusetts Water  Pollution
Abatement  Trust ($13.9 million projected in fiscal  1995), as well as grants to
municipalities under the school building assistance program to defray a  portion
of  the debt service  costs on local  school bonds ($179.2  million projected in
fiscal 1995).
 
    In January 1990, legislation  was passed to impose  a limit on debt  service
beginning  in  fiscal  1991,  providing  that no  more  than  10%  of  the total
appropriations in any fiscal  year may be expended  for payment of interest  and
principal  on general obligation debt (excluding the Fiscal Recovery Bonds). The
percentage of total  appropriations expended from  the budgeted operating  funds
for  debt service (excluding  debt service on Fiscal  Recovery Bonds) for fiscal
1994 is 5.6% (on a preliminary  unaudited basis) which is projected to  increase
to 5.9% in fiscal 1995.
 
    CERTAIN   LIABILITIES.    Among  the  material  future  liabilities  of  the
Commonwealth are  significant unfunded  general  liabilities of  its  retirement
systems  and a program to fund such  liabilities; a program whereby, starting in
1978, the  Commonwealth began  assuming full  financial responsibility  for  all
costs  of  the administration  of  justice within  the  Commonwealth; continuing
demands to raise aggregate aid to cities, towns, schools and other districts and
transit authorities above current levels;  and Medicaid expenditures which  have
increased each year since the
 
                                      B-4
<PAGE>
program  was initiated. The Commonwealth has  signed consent decrees to continue
improving mental health care and programs for the mentally retarded in order  to
meet   federal  standards,   including  those   governing  receipt   of  federal
reimbursements under  various programs,  and  the parties  in those  cases  have
worked cooperatively to resolve the disputed issues.
 
    As  a result  of comprehensive  legislation approved  in January,  1988, the
Commonwealth is  required,  beginning in  fiscal  1989 to  fund  future  pension
liabilities  currently and  to amortize the  Commonwealth's unfunded liabilities
over 40 years. The  estimated pension costs (inclusive  of current benefits  and
pension  reserves)  for fiscal  year 1996  are  $1.044 billion,  representing an
increase of 5.0% over estimated fiscal 1995 expenditures of $994.3 million.
 
    LITIGATION.   The  Commonwealth is  engaged  in various  lawsuits  involving
environmental  and related  laws, including an  action brought on  behalf of the
U.S. Environmental Protection Agency alleging violations of the Clean Water  Act
and  seeking to enforce  the clean-up of  Boston Harbor. The  MWRA, successor in
liability  to  the  Metropolitan   District  Commission,  has  assumed   primary
responsibility  for developing  and implementing  a court-approved  plan for the
construction of the  treatment facilities necessary  to achieve compliance  with
federal  requirements. Under the Clean Water Act, the Commonwealth may be liable
for costs of compliance in these or any other Clean Water cases if the MWRA or a
municipality is  prevented from  raising  revenues necessary  to comply  with  a
judgment. The MWRA currently projects that the total cost of construction of the
treatment  facilities  required under  the court's  order is  approximately $3.5
billion in current dollars, with approximately  $1.84 billion to be spent on  or
after July 1, 1994.
 
    The  Department of  Public Welfare  has been  sued for  the alleged unlawful
denial  of  personal  care  attendant  services  to  certain  disabled  Medicaid
recipients. The Superior Court has denied the plaintiff's motion for preliminary
injunction  and has also denied the  plaintiff's motion for class certification.
If the plaintiffs  were to  prevail on their  claims and  the Commonwealth  were
required  to  provide  all of  the  services  sought by  the  plaintiffs  to all
similarly situation persons, it would substantially increase in the annual  cost
to  the  Commonwealth  that these  services  might eventually  be  required. The
Department of Public Welfare currently estimates this increase to be as much  as
$200 million per year.
 
    There  are  also  actions  pending in  which  recipients  of  human services
benefits, such as welfare  recipients, the mentally  retarded, the elderly,  the
handicapped,  children, residents of state  hospitals and inmates of corrections
institutions, seek  expanded  levels  of  services and  benefits  and  in  which
providers  of services to such recipients challenge  the rates at which they are
reimbursed by  the Commonwealth.  To  the extent  that  such actions  result  in
judgments requiring the Commonwealth to provide expanded services or benefits or
pay  increased  rates, additional  operating and  capital expenditures  might be
needed to implement such judgments.
 
    The Massachusetts Hospital Association has brought an action challenging  an
element of the Medicaid rate setting methodologies for hospitals. On October 12,
1993,  the  case  was  settled  with the  hospital  association  and  most acute
hospitals, thereby  reducing  the  Commonwealth's  potential  liability  in  the
pending case or in related appeals to approximately $10 million.
 
    In  addition there are several tax  matters in litigation which could result
in significant refunds to taxpayers if decisions unfavorable to the Commonwealth
are rendered. In BAYBANK, ET AL. V. COMMISSIONER OF REVENUE, the banks challenge
the inclusion of income from tax exempt  obligations in the measure of the  bank
excise  tax. The  Appellate Tax Board  issued findings  of fact and  a report in
favor of the Commissioner of Revenue on September 30, 1993. The Supreme Judicial
Court heard the appeal on March 7,  1995. Taking into account all banks and  all
years  at issue (1974 through 1986), there  are 142 appeals consolidated in this
case. The  amount at  issue  is currently  estimated  to be  approximately  $1.4
billion,  which  amount  includes  interest of  approximately  $1.1  billion and
amounts involved in other  related applications for  abatement pending with  the
Commissioner of Revenue or with the Appellate Tax Board.
 
    In  March 30, 1995, the parties reported  to the Supreme Judicial Court that
they had agreed  in principle  to settle the  case and  related litigation.  The
agreement  in principle includes an agreement  that the Commonwealth will pay to
the banks $25 million, payable in installments of $10 million on August 1,  1996
and  August 1, 1997, and  $5 million and all  accrued interest on the settlement
amount on August 1,  1998, with an  option for the  Commonwealth to prepay  such
amounts.
 
    On  March 22,  1995, the  Supreme Judicial Court,  in its  opinion in PERINI
CORPORATION ET AL. V. COMMISSIONER OF REVENUE, held that certain deductions from
the net worth  measure of  the Massachusetts  corporate excise  tax violate  the
Commerce  Clause of the United States  Constitution. The court remanded the case
for entry of a declaration and  further proceedings, if necessary, to  determine
other  appropriate remedies. The  Commonwealth intends to file  a petition for a
writ of certiorari in the United States Supreme Court. The Department of Revenue
is analyzing the impact  of this decision, but  cannot yet determine the  likely
effect on future aggregate annual
 
                                      B-5
<PAGE>
corporate  excise tax  receipts. The  amount of taxes  and interest  at issue in
other cases is approximately $150 million.
 
    In  NATIONAL  ASSOCIATION  OF  GOVERNMENT  EMPLOYEES  V.  COMMONWEALTH,  the
Superior  Court  declared  that  a  line  item  in  the  Commonwealth's  general
appropriations  act  for  fiscal  1994  that  increased  the  state   employees'
percentage  share  of their  group  health insurance  premiums  from 10%  to 15%
violated the terms  of several collective  bargaining agreements, and  therefore
was invalid under the United States Constitution as regards employees covered by
the  agreements. The Commonwealth appealed the Superior Court's decision and the
Supreme Judicial Court has granted direct appellate review. Several other unions
have filed  a  companion suit  asserting  that the  premium  increase  similarly
violated  other  collective bargaining  agreements. The  latter  suit is  in its
initial stages. If the Superior Court  decision in favor of the state  employees
is   upheld,  the  Commonwealth's   aggregate  liability  is   estimated  to  be
approximately $32 million.
 
    A variety of  other civil suits  pending against the  Commonwealth may  also
affect  its future liabilities.  These include challenges  to the Commonwealth's
allocation of school aid under Section 9C of Chapter 29 of the General Laws  and
to  adopt a state employee furlough program. No prediction is possible as to the
ultimate outcome of these proceedings.
 
    Many factors, in addition  to those cited  above, do or  may have a  bearing
upon  the financial condition of the Commonwealth, including social and economic
conditions, many of which are not within the control of the Commonwealth.
 
    EXPENDITURE AND TAX LIMITATION  MEASURES.  Limits  have been established  on
state  tax revenues by legislation approved by  the Governor on October 25, 1986
and by an initiative petition  approved by the voters  on November 4, 1986.  The
Executive  Office for Administration and  Finance currently estimates that state
tax revenues will not reach the limit imposed by either the initiative  petition
or the legislative enactment in fiscal 1992.
 
    Proposition  2 1/2, passed by the voters in 1980, led to large reductions in
property taxes,  the major  source of  income for  cities and  towns, and  large
increases in state aid to offset such revenue losses. According to the Executive
Office  for Administration and Finance, all of the 351 cities and towns have now
achieved a property  tax level of  no more  than 2.5% of  full property  values.
Under the terms of Proposition 2 1/2, the property tax levy can now be increased
annually for all cities and towns, almost all by 2.5% of the prior fiscal year's
tax  levy  plus  2.5%  of  the  value  of  new  properties  and  of  significant
improvements to  property.  Legislation  has also  been  enacted  providing  for
certain  local  option  taxes.  A  voter  initiative  petition  approved  at the
statewide general election in November, 1990 further regulates the  distribution
of  Local Aid of no  less than 40% of  collections from individual income taxes,
sales and  use taxes,  corporate excise  taxes,  and the  balance of  the  state
lottery   fund.  If  implemented   in  accordance  with   its  terms  (including
appropriation of  the necessary  funds), the  petition as  approved would  shift
several hundred million dollars to direct Local Aid.
 
    OTHER  TAX MEASURES.   To provide  revenue to  pay debt service  on both the
deficit and  Medicaid-related borrowings  and to  fund certain  direct  Medicaid
expenditures,  legislation  was enacted  imposing an  additional tax  on certain
types of personal income for 1989 and 1990 taxable years at rates of 0.375%  and
0.75%  respectively, effectively raising the tax rate  of 1989 from 5% to 5.375%
and for 1990 to 5.75%. Recent legislation has effectively further increased  tax
rates  to 5.95% for  tax year 1990 to  6.25% for tax year  1991 and returning to
5.95% for tax year 1992 and subsequent  tax years. The tax is applicable to  all
personal   income  except   income  derived   from  dividends,   capital  gains,
unemployment compensation,  alimony,  rent, interest,  pensions,  annuities  and
IRA/Keogh  distributions.  The  income  tax rate  on  other  interest (excluding
interest on obligations  of the United  States and of  the Commonwealth and  its
subdivisions),  dividends  and net  capital gains  (after  a 50%  reduction) was
increased from 10% to 12%  for tax year 1990  and subsequent years, by  recently
enacted legislation.
 
    ESTATE  TAX REVISIONS.   The fiscal  1993 budget  included legislation which
gradually phases out the current Massachusetts estate tax and replaces it with a
"sponge tax" in 1997.  The "sponge tax"  is based on the  maximum amount of  the
credit  for state taxes allowed for federal  estate tax purposes. The estate tax
is phased out  by means  of annual  increases in  the basic  exemption from  the
current  $200,000  level.  The  exemption is  increased  to  $300,000  for 1993,
$400,000 for 1994,  $500,000 for 1995  and $600,000 for  1996. In addition,  the
legislation  includes a full marital deduction  starting July 1, 1994. Currently
the marital deduction  is limited  to 50%  of the  Massachusetts adjusted  gross
estate.  The  static  fiscal impact  of  the phase  out  of the  estate  tax was
estimated to be approximately $24.8 million  in fiscal 1994 and is estimated  to
be approximately $72.5 million in fiscal 1995.
 
    OTHER  ISSUERS OF  MASSACHUSETTS OBLIGATIONS.   There are a  number of state
agencies, instrumentatlities and political subdivisions of the Commonwealth that
issue Municipal Obligations, some  of which may  be conduit revenue  obligations
payable  from payments  from private  borrowers. These  entities are  subject to
various economic  risks  and  uncertainties,  and  the  credit  quality  of  the
securities issued by them may vary considerably from the
 
                                      B-6
<PAGE>
credit  quality  of obligations  backed  by the  full  faith and  credit  of the
Commonwealth. The brief summary above does  not address, nor does it attempt  to
address, any difficulties and the financial situations of those other issuers of
Massachusetts Obligations.
 
MASSACHUSETTS TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The  following tables show the approximate taxable estimated current returns
for individuals  that are  equivalent to  tax-exempt estimated  current  returns
under  combined Federal and  state taxes, using  published 1996 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.  The
combined  state and Federal tax  brackets shown reflect the  fact that state tax
payments are currently  deductible for Federal  tax purposes. The  Massachusetts
state tax rate shown is the rate at which interest is taxed. Certain other types
of  income are taxed at other rates. The  table does not reflect any local taxes
or any taxes other  than personal income taxes.  The tables illustrate what  you
would  have to  earn on  taxable investments  to equal  the tax-exempt estimated
current return for your  income tax bracket. A  taxpayer's marginal tax rate  is
affected  by both his taxable income and  his adjusted gross income. Locate your
adjusted gross and  your taxable  income (which  is your  adjusted gross  income
reduced by any deductions and exemptions), then locate your tax bracket based on
joint  or single  tax filing.  Read across  to the  equivalent taxable estimated
current return you would need to match the tax-free income.

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

    The attached final Prospectus for a prior Series is hereby used as a
preliminary Prospectus for the above-stated Series.  The narrative 
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 
therein, the specific trusts included in this Series when deposited may
differ from such trusts.  Information with respect to the actual trusts to
be included, pricing, the number of Units, dates and summary information
regarding the characteristics of securities to be deposited in this Series
is not now available and will be different since each Series has a unique

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 
interest rates and offering prices of the securities in this Series and may
vary materially from that of the previous Series.
