     BOTH PARTS OF THE PROSPECTUS SHOULD BE RETAINED FOR FUTURE REFERENCE.
    
 
   
    Florida  Insured  Trust  221  (the  "Trust")  consists  of  a  portfolio  of
interest-bearing obligations issued  by or on  behalf of the  State of  Florida,
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 Florida
intangibles tax, to the extent indicated below.
    
    The objectives of the  Trust are income exempt  from Federal income tax  and
Florida  intangibles tax,  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 10 obligations  issued by entities
located in Florida. 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:

</TABLE>
    
 
   
    Approximately  44.4% of the  aggregate principal amount of  the Bonds in the
Trust (accounting for approximately 43.4% of the aggregate offering price of the
Bonds) are original issue discount obligations. Certain of these original  issue
discount  obligations, amounting to  2.9% of the  aggregate principal amount and
 .6% of the aggregate offering price of the Bonds in the Trust, are "zero coupon"
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 Dedicated-Tax
Supported Revenue Issuers whose revenues are subject to certain risks  including
changes  in  the local  economy and  the ability  to collect  taxes in  a timely
fashion. The  Trust is  also considered  to be  concentrated in  Bonds of  Water
and/or  Sewer  Revenue  Issuers  whose revenues  are  subject  to  certain risks
including problems obtaining timely and  adequate rate increases and  population
decline  resulting  in  decreased  user  fees. 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.

                              FLORIDA RISK FACTORS
 
    The financial  condition of  the State  of Florida  is affected  by  various
national,   economic,   social  and   environmental  policies   and  conditions.
Additionally, Constitutional and statutory limitations imposed on the State  and
its  local governments concerning taxes, bond indebtedness and other matters may
constrain the revenue-generating capacity of the State and its local governments
and, therefore,  the  ability of  the  issuers of  the  Bonds to  satisfy  their
obligations.  The State Constitution and statutes mandate that the State budget,
as a whole, and each separate fund  within the State budget, be kept in  balance
from  currently  available revenues  each fiscal  year. Additionally,  the State
Constitution prohibits issuance of State obligations to fund State operations.
 
    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  State  continues  to be  dependent  on  the
construction and construction related manufacturing industries. These industries
tend  to  be highly  cyclical and  there  is no  assurance that  Florida's rapid
population growth,  which drove  these industries  in the  past, will  continue.
Tourism  is  also one  of the  State's most  important industries.  Because many
international travelers visit  Florida, an  increase in  the value  of the  U.S.
dollar  adversely affects this industry. Moreover,  Florida could be impacted by
problems in the  agricultural sector,  including crop  failures, severe  weather
conditions  or other agricultural-related problems,  particularly with regard to
the citrus and sugar industries.
 
    The State is a party to numerous lawsuits in which an adverse final decision
could materially affect the State's governmental operations and consequently its
ability to pay debt service on its obligations.
 
    The State maintains a bond rating of  Aa and AA from Moody's and Standard  &
Poor's,  respectively, on the majority of its general obligation bonds, although
the rating of  a particular  series of revenue  bonds relates  primarily to  the
project,  facility, or  other revenue  resource from  which such  series derives
funds for repayment.
 
    Further information concerning  Florida 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
 
    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.
 
    The assets of the Trust will consist solely of interest-bearing  obligations
issued  by or on behalf of the  State of Florida, its political subdivisions and
authorities or by  the Commonwealth of  Puerto Rico, Guam,  the Virgin  Islands,
American Samoa, or the Northern Mariana Islands (the "Florida Bonds").
 
    In  the opinion  of Carlton, Fields,  Ward, Emmanuel, Smith  & Cutler, P.A.,
special counsel for the Trust for Florida tax matters, under existing law:
 
                                     3 of 7
<PAGE>
    For Florida state income tax purposes, the Trust will not be subject to  the
Florida  income tax  imposed by  the Florida Code  so long  as the  Trust has no
income subject  to  federal taxation.  In  addition, political  subdivisions  of
Florida do not impose any income taxes.
 
    Because  Florida does not impose an income tax on individuals, non-corporate
Unitholders will not be subject to any Florida income tax on income realized  by
the  Trust. Each corporate Unitholder will be subject to Florida income taxation
on its share of the income realized by the Trust notwithstanding the tax  exempt
status  of the  interest received  from any  bonds under  Section 103(a)  of the
Internal Revenue Code  of 1986  or any other  federal law,  unless the  interest
income  constitutes nonbusiness  income. Nevertheless,  any corporate Unitholder
that has its commercial  domicile in Florida will  be taxable under the  Florida
Code on its share of the Trust income which constitutes nonbusiness income.
 
    Trust  Units will be subject to Florida  estate tax only if owned by Florida
residents, certain natural persons not domiciled in Florida, or certain  natural
persons  not residents of the United States.  However, the Florida estate tax is
limited to  the amount  of the  credit allowable  under the  applicable  Federal
Revenue  Act (currently  Section 2011  (and in some  cases Section  2102) of the
Internal Revenue Code of 1986, as amended) for death taxes actually paid to  the
several states.
 
    Neither  the Florida Bonds nor  the Units will be  subject to the Florida ad
valorem property tax or Florida sales or use tax.
 
    Because Bonds issued by the State  of Florida or its political  subdivisions
or  by the Commonwealth of Puerto Rico, Guam, the Virgin Islands, American Samoa
and the Northern  Mariana Islands  are exempt from  Florida intangible  personal
property  taxation under  Chapter 199, Florida  Statutes, as  amended, the Trust
will not be subject  to Florida intangible personal  property tax. In  addition,
the  Unitholders will not be subject to Florida intangible personal property tax
on the Units.

In addition,  the difference  between the  Trustee's determination  of  Offering
Price  and Bid Price (as a percentage of principal amount) is .50%. 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
FLORIDA INSURED TRUST 221:
    
 
   
    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
Florida  Insured Trust  221 (contained in  Nuveen Tax-Exempt  Unit Trust, Series
838), as of December 1, 1995. 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 Florida Insured Trust  221 as of December 1, 1995,  in
conformity with generally accepted accounting principles.

    New  York  Insured  Trust  244  (the "Trust")  consists  of  a  portfolio of
interest-bearing obligations issued by  or on behalf of  the State of New  York,
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 New York
state and city income taxes, 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 11 obligations  issued by  entities
located  in New York. 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  28.0% of the  aggregate principal amount of  the Bonds in the
Trust (accounting for approximately 24.8% of the aggregate offering price of the
Bonds) are original issue discount obligations. Certain of these original  issue
discount  obligations, amounting to  6.0% of the  aggregate principal amount and
2.4% of  the aggregate  offering price  of the  Bonds in  the Trust,  are  "zero
coupon"  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.
    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.

                             NEW YORK RISK FACTORS
 
    The  financial condition  of the  State of New  York is  affected by various
national,  economic,   social  and   environmental  policies   and   conditions.
Additionally,  Constitutional and statutory limitations imposed on the State and
its local governments concerning taxes, bond indebtedness and other matters  may
constrain the revenue-generating capacity of the State and its local governments
and,  therefore,  the ability  of  the issuers  of  the Bonds  to  satisfy their
obligations. Historically, the State  has been one of  the wealthiest states  in
the  nation; however, for decades  the State economy has  grown more slowly than
that of the nation as a  whole, gradually eroding the State's relative  economic
affluence.
 
    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  economy  of  the  State  continues  to be
influenced by the financial health of the City of New York, which faces  greater
competition  as other major cities  develop financial and business capabilities.
The State has for many years had a very high state and local tax burden relative
to other states. The burden of State and local taxation, in combination with the
many other  causes of  regional  economic dislocation,  has contributed  to  the
decisions  of some businesses and individuals to relocate outside, or not locate
within, the State.
 
    The State is party to numerous  lawsuits in which an adverse final  decision
could materially affect the State's governmental operations and consequently its
ability  to pay debt service on its  obligations. On January 21, 1994, the State
entered into a  settlement with Delaware  with respect to  STATE OF DELAWARE  V.
STATE OF NEW YORK. The State made an immediate $35 million payment and agreed to
make  a $33 million  annual payment in each  of the next  five fiscal years. The
State has not settled with other parties to the litigation and will continue  to
incur litigation expenses as to those claims.
 
    All  outstanding general  obligation bonds  of the  State are  rated "A-" by
Standard and Poor's and "A" by Moody's.
 
    Further information concerning New  York 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
 
    For a discussion of the Federal tax status of income earned on Trust  Units,
see "WHAT IS THE TAX STATUS OF UNITHOLDERS?" in Part B of this Prospectus.
 
    In  the opinion of Edwards  & Angell, special counsel  for the Trust for New
York tax matters, under existing law:
 
        Interest  on  obligations  issued  by   New  York  State,  a   political
    subdivision  thereof, Puerto  Rico, the  Virgin Islands,  Guam, the Northern
    Mariana Islands,  or  other possessions  of  the United  States  within  the
    meaning  of Section 103(c) of the Internal  Revenue Code of 1986, as amended
    ("New York Obligations"), which would be
 
                                     3 of 7
<PAGE>
    exempt from New York State or New York City personal income tax if  directly
    received by a Unitholder, will retain its status as tax-exempt interest when
    received by the Trust and distributed to such Unitholder.
 
        Interest  (less amortizable premium, if any) derived from the Trust by a
    resident of New  York State  (or New York  City) in  respect of  obligations
    issued  by states other than New York (or their political subdivisions) will
    be subject to New York State (or New York City) personal income tax.
 
        A Unitholder who is a resident of New York State (or New York City) will
    be subject to New  York State (or  New York City)  personal income tax  with
    respect  to gains realized when  New York Obligations held  in the Trust are
    sold, redeemed or paid at maturity  or when the Unitholder's Units are  sold
    or  redeemed;  such gain  will  equal the  proceeds  of sale,  redemption or
    payment less the tax basis of the  New York Obligation or Unit (adjusted  to
    reflect  (a) the amortization  of premium or  discount, if any,  on New York
    Obligations held by  the Trust,  (b) accrued original  issue discount,  with
    respect  to  each  New York  Obligation  which,  at the  time  the  New York
    Obligation was issued, had original issue  discount, and (c) the deposit  of
    New   York  Obligations  with  accrued  interest  in  the  Trust  after  the
    Unitholder's settlement date).
 
        Interest or gain from  the Trust derived  by a Unitholder  who is not  a
    resident  of New York  State (or New York  City) will not  be subject to New
    York State (or  New York  City) personal income  tax, unless  the Units  are
    property  employed in a business, trade, profession or occupation carried on
    in New York State (or New York City).
 
        In the case  of the  Trust, amounts  paid under  the insurance  policies
    representing maturing interest on defaulted New York Obligations held by the
    Trustee  in the Trust  will be excludable  from New York  State and New York
    City income if, and  to the same  extent as, such  interest would have  been
    excludable if paid by the respective issuer.
 
        For  purposes of the New  York State and New  York City franchise tax on
    corporations, Unitholders which are subject to such tax will be required  to
    include in their entire net income any interest or gains distributed to them
    even   though  distributed  in  respect  of  obligations  of  any  state  or
    subdivision thereof including New York.
 
        If borrowed funds are used to purchase Units in the Trust, all (or part)
    of the interest  on such indebtedness  will not be  deductible for New  York
    State  and  New  York  City  tax purposes.  The  purchase  of  Units  may be
    considered to have been made with borrowed funds even though such funds  are
    not directly traceable to the purchase of Units in the Trust.

In  addition,  the difference  between the  Trustee's determination  of Offering
Price and Bid Price (as a percentage of principal amount) is .50%. 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
NEW YORK INSURED TRUST 244:
    
 
   
    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 New
York Insured Trust 244 (contained in Nuveen Tax-Exempt Unit Trust, Series  838),
as of December 1, 1995. 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 New York Insured Trust 244 as of December 1, 1995,  in
conformity with generally accepted accounting principles.

    Ohio   Insured  Trust  130   (the  "Trust")  consists   of  a  portfolio  of
interest-bearing obligations  issued by  or  on behalf  of  the State  of  Ohio,
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 Ohio
state and local 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  9 obligations  issued by entities
located in Ohio. 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 5.9% of  the aggregate principal  amount of the  Bonds in  the
Trust  (accounting for approximately 1.4% of the aggregate offering price of the
Bonds) are original issue discount obligations. Certain of these original  issue
discount  obligations, amounting to  5.9% of the  aggregate principal amount and
1.4% of  the aggregate  offering price  of the  Bonds in  the Trust,  are  "zero
coupon"  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 Water and/or Sewer
Revenue Issuers whose revenues are  subject to certain risks including  problems
obtaining timely and adequate rate increases and population decline resulting in
decreased user fees. The Trust is also 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.

BECAUSE CERTAIN OF THE BONDS IN THE TRUST WILL NOT BE DELIVERED TO THE TRUSTEE UNTIL AFTER THE SETTLEMENT DATE FOR
A  PURCHASE OF UNITS MADE ON THE DATE OF DEPOSIT, INTEREST THAT ACCRUES ON THOSE BONDS BETWEEN THE DATE OF DEPOSIT

  OHIO INSURED TRUST............  DECEMBER 14, 1995   $           .04                     4.97        %
</TABLE>
    
 
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.

                               OHIO RISK FACTORS
 
    The  financial  condition  of  the  State of  Ohio  is  affected  by various
national,  economic,   social  and   environmental  policies   and   conditions.
Additionally,  Constitutional and statutory limitations imposed on the State and
its local governments concerning taxes, bond indebtedness and other matters  may
constrain the revenue-generating capacity of the State and its local governments
and,  therefore,  the ability  of  the issuers  of  the Bonds  to  satisfy their
obligations. The  State operates  on the  basis  of a  fiscal biennium  for  its
appropriations  and expenditures, and is precluded by law from ending its fiscal
year or fiscal biennium in a deficit position.
 
    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. While diversifying more into the service and other
non-manufacturing areas, the Ohio economy continues  to rely in part on  durable
goods  manufacturing,  largely  concentrated in  motor  vehicles  and equipment,
steel, rubber products and household  appliances. As a result, general  economic
activity,  as  in many  other industrially-developed  states,  tends to  be more
cyclical than in some other states and in the nation as a whole. Agriculture  is
an  important segment of the economy, with over half the State's area devoted to
farming and approximately 15% of total employment in agribusiness.
 
    The State is a party to numerous lawsuits in which an adverse final decision
could materially affect the State  governmental operations and consequently  its
ability to pay debt service on its obligations.
 
    Further  information  concerning State  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
 
    For  a discussion of the Federal tax status of income earned on Trust Units,
see "WHAT IS THE TAX STATUS OF UNITHOLDERS?" in Part B of this Prospectus.
 
    The Trust is comprised primarily  of interest-bearing obligations issued  by
or  on behalf of the State of  Ohio, political subdivisions thereof, or agencies
or instrumentalities thereof (the "Ohio Obligations"), or by the governments  of
Puerto   Rico,  the  Virgin  Islands,  the  Northern  Mariana  Islands  or  Guam
(collectively, "Obligations").
 
    In the opinion  of Squire, Sanders  & Dempsey, special  Ohio counsel to  the
Trust,  provided that at  all times at least  fifty percent of  the value of the
total assets of the Trust consist of Ohio Obligations, or similar obligations of
other states or their subdivisions, under existing Ohio law:
 
        The Trust is not taxable as  a corporation or otherwise for purposes  of
    the  Ohio personal income  tax, Ohio school district  income taxes, the Ohio
    corporation franchise tax, or the Ohio dealers in intangibles tax.
 
                                     3 of 7
<PAGE>
        Income of the Trust will be treated as the income of the Unitholders for
    purposes of the Ohio personal income  tax and municipal and school  district
    income taxes in Ohio and the Ohio corporation franchise tax in proportion to
    the respective interest therein of each Unitholder.
 
        Interest  on  Obligations held  by  the Trust  is  exempt from  the Ohio
    personal income tax, and municipal and school district income taxes in Ohio,
    and is excluded from the net  income base of the Ohio corporation  franchise
    tax when distributed or deemed distributed to Unitholders.
 
        Proceeds  paid under insurance  policies, if any, to  the Trustee of the
    Trust representing maturing  interest on defaulted  obligations held by  the
    Trust  that is  excluded from gross  income for federal  income tax purposes
    will be exempt from  the Ohio personal income  tax and municipal and  school
    district  income  taxes  in  Ohio  and  the  net  income  base  of  the Ohio
    corporation franchise tax.
 
        Gains and losses realized on the sale, exchange or other disposition  by
    the Trust of Ohio Obligations are excluded in determining adjusted gross and
    taxable  income for purposes of the  Ohio personal income tax, and municipal
    and school district  income taxes  in Ohio, and  are excluded  from the  net
    income base of the Ohio corporation franchise tax when distributed or deemed
    distributed to Unitholders.

*_ These  Bonds, or  a portion  thereof, have  delivery dates  beyond the normal
   settlement date. Their expected delivery  dates range from December 11,  1995
   to  December 14, 1995. Contracts relating  to Bonds with delivery dates after
   the date of settlement  for purchase made on  the Date of Deposit  constitute
   approximately  36%  of  the aggregate  principal  amount of  the  Trust. (See
   "COMPOSITION OF TRUSTS" in Part B of this Prospectus.)
    
 
- ------------
 
    (1) The Sponsor's contracts to purchase  Bonds were entered into during  the
period  from November 29, 1995 to November 30, 1995. 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 .45%. 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
OHIO INSURED TRUST 130:
    
 
   
    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  Ohio
Insured Trust 130 (contained in Nuveen Tax-Exempt Unit Trust, Series 838), as of
December  1,  1995. 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 Ohio Insured  Trust 130  as of December  1, 1995, in
conformity with generally accepted accounting principles.
    
 
                                                             ARTHUR ANDERSEN LLP

             PROSPECTUS -- PART B
            (GENERAL TERMS)
              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
THE TRUSTEE AT 770 BROADWAY, NEW YORK, NY 10003 OR (800) 257-8787.
 
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
PART A AND PART B OF THIS PROSPECTUS FOR FUTURE REFERENCE.

RISK FACTORS. An investment in a Trust  should be made with an understanding  of
the risks associated therewith, including, among other factors, the inability of
the issuer or an insurer to pay the principal of or interest on a bond when due,
volatile interest rates, early call provisions, and changes to the tax status of
the Bonds. See Part A of this Prospectus and "RISK FACTORS."
 
UNITS OF THE TRUST ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR ENDORSED
BY, ANY BANK AND ARE NOT FEDERALLY INSURED OR OTHERWISE PROTECTED BY THE FEDERAL

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.

    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:

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:

 *Breakpoint sales charges are computed both on a dollar basis and on the  basis
  of  the  number of  Units  purchased, using  the  equivalent of  500  Units to
  $50,000, 2,500 Units  to $250,000,  etc., and will  be applied  on that  basis
  which is more favorable to the purchaser.
 
    The  secondary market sales charges above are  expressed as a percent of the
net amount invested; expressed  as a percent of  the Public Offering Price,  the
maximum  sales charge on  any Trust, including one  consisting entirely of Bonds
with 16 years  or more to  maturity, would be  5.50% (5.820% of  the net  amount
invested).  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.

<PAGE>
    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

<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
<PAGE>
    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:

    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.
 
                                       21
<PAGE>
    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.

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
 
                                       6

Association. Each  insurance company's  participation is  backed by  all of  its
assets.  However,  each insurance  company is  a  multiline insurer  involved in
several lines of insurance other than  municipal bond insurance, and the  assets
of  each insurance  company also  secure all of  its other  insurance policy and
surety bond obligations.
 
    The following table sets forth certain unaudited financial information  with
respect  to  the  five  insurance  companies  comprising  the  Association.  The
statistics, which have been furnished by the Association, are as reported by the
insurance  companies  to  the  New  York  State  Insurance  Department  and  are
determined in accordance with statutory accounting principles. No representation
is  made herein as to the accuracy or  adequacy of such information or as to the
absence of material adverse changes in  such information subsequent to the  date
thereof.  In addition,  these numbers  are subject to  revision by  the New York
State Insurance Department which, if revised, could either increase or  decrease
the amounts.

   The  Moody's  Investors Service  rating of  the  Insurer should  be evaluated
independently of the  Standard & Poor's  Corporation rating of  the Insurer.  No
application  has  been  made to  any  other  rating agency  in  order  to obtain
additional ratings  on the  Bonds.  The ratings  reflect the  respective  rating
agency's  current  assessment of  the creditworthiness  of  the Insurer  and its
ability to  pay  claims  on  its policies  of  insurance  (See  "Description  of
Ratings.")  Any further explanation as to  the significance of the above ratings
may be obtained only from the applicable rating agency.
 
   The above ratings are not recommendations to buy, sell or hold the Bonds, and
such ratings may be subject to revision or withdrawal at any time by the  rating
agencies. Any downward revision or withdrawal of either or both ratings may have
an adverse effect on the market price of the Bonds.
 
   Because the insurance on the Bonds will be effective so long as the Bonds are
outstanding, such insurance will be taken into account in determining the market
value  of the Bonds and therefore some value attributable to such insurance will
be included in the value of the Units of the Insured Trusts. The insurance  does
not, however, guarantee the market value of the Bonds or of the Units.
 
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
 
                                       7
<PAGE>
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 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.

<PAGE>
THE CALIFORNIA FUND
 
    The  California Fund has  the objective of  providing, through investment in
professionally managed portfolios of California municipal obligations, as high a
level of current interest income exempt from both Federal and California  income
taxes as is consistent with the investment policies of each of the portfolios of
the  California Fund  and with  preservation of  capital. Each  portfolio of the
California Fund may include  temporary investments that may  be subject to  tax.
California Unitholders may reinvest in one of three portfolios of the California
Fund:  The Nuveen California Tax-Free Value  Fund, the Nuveen California Insured
Tax-Free Value Fund and the Nuveen California Tax-Free Money Market Fund.
 
    The Nuveen California  Tax-Free Value  Fund invests  primarily in  long-term
investment  grade California  tax-exempt bonds  (I.E., bonds  rated in  the four
highest categories by  Moody's or Standard  & Poor's or,  if unrated, that  have
equivalent credit characteristics). The Nuveen California Insured Tax-Free Value
Fund  invests primarily  in the  same type  of investments  as the  Special Bond
Portfolio, each of which is covered by insurance guaranteeing the timely payment
of principal  and  interest  or  is  backed by  a  deposit  of  U.S.  Government
securities.
 
    The  Nuveen  California  Tax-Free  Money Market  Fund  invests  primarily in
high-quality short term California tax-  exempt money market instruments  (I.E.,
obligations  rated in the two highest categories by Moody's or Standard & Poor's
or, if unrated,  that have  equivalent credit  characteristics). This  portfolio
will  include  only  obligations  maturing  within one  year  from  the  date of
acquisition, will maintain an average maturity of all investments of 120 days or
less, will value its portfolio at amortized cost and will seek to maintain a net
asset value of $1.00 per share. The Nuveen California Tax-Free Money Market Fund
provides for an expedited wire redemption privilege.
 
THE TAX-FREE BOND FUND
 
    The Tax-Free Bond Fund consists  of the Nuveen Massachusetts Tax-Free  Value
Fund,  the Nuveen New York  Tax-Free Value Fund, the  Nuveen Ohio Tax-Free Value
Fund, and the Nuveen  New Jersey Tax-Free Value  Fund, which are each  available
for  reinvestment to Unitholders who  are residents of the  state for which such
portfolio is  named. The  Tax-Free Bond  Fund has  the objective  of  providing,
through  investment in a professionally managed portfolio of municipal bonds, as
high a level of current interest income exempt both from Federal income tax  and
from  the  income  tax  imposed  by  each  portfolio's  designated  state  as is
consistent with preservation of capital. The  Tax-Free Bond Fund may include  in
each  of its  portfolios tax-exempt  bonds rated Baa  or BBB  or better; unrated
bonds  which,  in   the  opinion   of  the  investment   adviser,  have   credit
characteristics  equivalent to  bonds rated  Baa or  BBB or  better; and certain
temporary investments, including securities the  interest income from which  may
be subject to Federal and state income tax.
 
THE INSURED BOND FUND
 
    The  Insured Bond Fund  consists of the Nuveen  Insured Municipal Bond Fund,
the Nuveen Massachusetts  Insured Tax-Free Value  Fund and the  Nuveen New  York
Insured  Tax-Free  Value  Fund, which  are  each available  for  reinvestment to
Unitholders. (The Massachusetts and  New York Portfolios  are available only  to
those  Unitholders who  are residents  of the state  for which  the portfolio is
named.) The Insured Bond Fund has the objective of providing, through investment
in professionally managed  portfolios of  municipal bonds,  as high  a level  of
current  interest income exempt from both Federal income tax and, in the case of
designated state portfolios,  from the  income tax imposed  by each  portfolio's
designated  state, as  is consistent with  preservation of  capital. The Insured
Bond Fund may include in each of its portfolios the same type of investments  as
the  Tax-Free Bond Fund, each of which  is covered by insurance guaranteeing the
timely payment of  principal and  interest or  is backed  by a  deposit of  U.S.
Government securities.
 
THE MONEY MARKET FUND
 
    The  Money Market Fund  consists of the  Nuveen Massachusetts Tax-Free Money
Market Fund and the Nuveen New York  Tax-Free Money Market Fund, which are  each
available  for reinvestment  to Unitholders who  are residents of  the state for
which such portfolio is named. The Money Market Fund includes in its  portfolios
only  obligations  maturing  within  one  year  from  the  date  of acquisition,
maintains an average  maturity of  120 days or  less, values  its portfolios  at
amortized  cost and seeks to maintain a net  asset value of $1.00 per share. The
Money Market  Fund  has  the  objective  of  providing,  through  investment  in
professionally   managed  portfolios   of  high   quality  short-term  municipal
obligations, as high a level of current interest income exempt both from Federal
income tax and from the income tax imposed by each portfolio's designated  state
as  is consistent with stability of  principal and the maintenance of liquidity.
The  Money  Market  Fund  may  include  in  each  of  its  portfolios  municipal
obligations  rated Aaa, Aa, MIG-1, MIG- 2, VMIG-1, VMIG-2, Prime 1 or Prime 2 by
Moody's or  AAA, AA,  SP-1,  SP-2, A-1  or A-2  by  Standard &  Poor's;  unrated
municipal   obligations  that,  in  the   opinion  of  the  investment  adviser,
 
                                       9

have credit  characteristics  equivalent  to obligations  rated  as  above;  and
temporary investments that may be subject to Federal and state income tax.
 
THE MULTISTATE TRUST
 
    The Multistate Trust consists of the Nuveen Arizona Tax-Free Value Fund, the
Nuveen Florida Tax-Free Value Fund, the Nuveen Maryland Tax-Free Value Fund, the
Nuveen  Michigan Tax-Free Value Fund, the Nuveen New Jersey Tax-Free Value Fund,
the Nuveen Pennsylvania  Tax-Free Value Fund  and the Nuveen  Virginia Tax  Free
Value  Fund, which  are each available  for reinvestment to  Unitholders who are
residents of the state for which  such portfolio is named. The Multistate  Trust
has  the objective of providing, through  investment in a professionally managed
portfolio of municipal bonds, as high a level of current interest income  exempt
from  both regular Federal  income tax and the  applicable state personal income
tax as is  consistent with  preservation of  capital. The  Multistate Trust  may
include  in each  of its  portfolios tax-exempt  bonds rated  "Baa" or  "BBB" or
better, unrated bonds  which, in  the opinion  of the  investment advisor,  have
credit  characteristics  equivalent to  bonds rated  "baa"  or "BBB"  or better,
limited to  no more  than 20%  of  the Multistate  Trust's assets,  and  certain
temporary investments that may be subject to Federal and state income tax.
 
    Each  person who purchases Units of a  Trust may become a participant in the
Accumulation Plan and elect  to have his  or her distributions  on Units of  the
Trust  invested directly in shares of one of the Accumulation Funds. Reinvesting
Unitholders  may  select  any  interest  distribution  plan.  Thereafter,   each
distribution  of  interest  income  or  principal  on  the  participant's  Units
(principal only in  the case of  a Unitholder  who has chosen  to reinvest  only
principal  distributions) will, on the applicable distribution date, or the next
day on which the New  York Stock Exchange is  normally open ("business day")  if
the  distribution  date is  not  a business  day,  automatically be  received by
Shareholder Services, Inc., transfer agent  for each of the Accumulation  Funds,
on  behalf of such participant  and applied on that  date to purchase shares (or
fractions thereof)  of  the Accumulation  Fund  chosen  at net  asset  value  as
computed  as of 4:00 p.m. eastern time on each such date. All distributions will
be reinvested  in the  Accumulation Fund  chosen  and no  part thereof  will  be
retained  in a separate  account. These purchases  will be made  without a sales
charge.

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;
 
- ----------
*As published by the rating companies.
 
                                       11
<PAGE>
    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.
 
    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
 
                                       12
<PAGE>
greater  amplitude  or  there  may  be other  elements  present  which  make the
long-term risks  appear somewhat  larger than  in Aaa  securities. Their  market
value  is  virtually  immune  to  all  but  money  market  influences,  with the
occasional exception of oversupply in a few specific instances.
 
    A--Bonds which are rated A possess many favorable investment attributes  and
are  to be considered as upper medium grade obligations. Factors giving security
to principal and interest are considered  adequate, but elements may be  present
which  suggest a susceptibility to impairment sometime in the future. The market
value of A-rated bonds may be influenced to some degree by economic  performance
during  a sustained period of depressed business conditions, but, during periods
of normalcy,  A-rated  bonds  frequently  move  in  parallel  with  Aaa  and  Aa
obligations,  with  the occasional  exception of  oversupply  in a  few specific
instances.
 
    Moody's bond rating  symbols may  contain numerical modifiers  of a  generic
rating  classification. The modifier 1 indicates that the bond ranks at the high
end of  its category;  the modifier  2 indicates  a mid-range  ranking; and  the
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
 
    Baa--Bonds  which are rated Baa are  considered as medium grade obligations,
i.e., they are neither  highly protected nor  poorly secured. Interest  payments
and  principal security appear  adequate for the  present but certain protective
elements may be lacking or may  be characteristically unreliable over any  great
length  of time. Such  bonds lack outstanding  investment characteristics and in
fact have speculative  characteristics as  well. The market  value of  Baa-rated
bonds  is more  sensitive to changes  in economic circumstances,  and aside from
occasional speculative factors applying to some bonds of this class, Baa  market
valuations  move in parallel  with Aaa, Aa  and A obligations  during periods of
economic normalcy, except in instances of oversupply.
 
    Con. (--)--Bonds for which the security depends upon the completion of  some
act  or the  fulfillment of  some condition  are rated  conditionally. These are
bonds secured by (a)  earnings of projects under  construction, (b) earnings  of
projects  unseasoned  in  operation  experience, (c)  rentals  which  begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes  probable credit stature upon  completion
of construction or elimination of basis of condition.
 
    NOTE RATINGS:
 
    MIG 1--  This  designation denotes  best  quality. There  is  present strong
           protection by established cash  flows, superior liquidity support  or
           demonstrated broad-based access to the market for refinancing.
 
    MIG 2--  This designation  denotes high  quality. Margins  of protection are
           ample although not so large as in the preceding group.

                                   APPENDIX A
                               FLORIDA DISCLOSURE
 
ECONOMIC FACTORS--FLORIDA
 
    POPULATION.   In 1980,  Florida was the  seventh most populous  state in the
U.S. The State has grown dramatically since then and as of April 1, 1993,  ranks
fourth  with an estimated  population of 13.6  million. Florida's attraction, as
both a growth and retirement state, has kept net migration fairly steady with an
average of 292,988 new residents a year from 1983 through 1993. The U.S. average
population increase since  1982 is  about 1% annually,  while Florida's  average
annual  rate of  increase is  about 2.5%.  Florida continues  to be  the fastest
growing of the ten largest states.  This strong population growth is one  reason
the State's economy is performing better than the nation as a whole. In addition
to attracting senior citizens to Florida as a place for retirement, the State is
also  recognized as attracting a significant  number of working age individuals.
Since 1983, the  prime working age  population (18-44) has  grown at an  average
annual rate of 2.6%. The share of Florida's total working age population (18-59)
to  total State population is  approximately 54%. This share  is not expected to
change appreciably into the twenty-first century.
 
    INCOME.  The  State's personal  income has  been growing  strongly the  last
several  years and has generally  outperformed both the U.S.  as a whole and the
southeast in particular, according  to the U.S. Department  of Commerce and  the
Florida  Consensus  Economic Estimating  Conference.  This is  because Florida's
population has been growing at a very  strong pace and, since the early  1970's,
the State's economy has diversified so as to provide a broader economic base. As
a result, Florida's real per capita personal income has tracked closely with the
national  average and has  tracked above the southeast.  From 1984 through 1993,
the State's real per capita  income rose at an average  of 5.4% per year,  while
the national real per capita income increased at an average of 5.5% per year.
 
    Because  Florida has  a proportionately  greater retirement  age population,
property income (dividends,  interest, and rent)  and transfer payments  (Social
Security  and pension  benefits, among other  sources of  income) are relatively
more important  sources  of  income.  For example,  Florida's  total  wages  and
salaries  and other labor income in 1993 was 62% of total personal income, while
a similar figure for  the nation was 72%.  Transfer payments are typically  less
sensitive  to the business  cycle than employment income  and, therefore, act as
stabilizing forces in weak economic periods.
 
    The State's per capita personal income in 1993 of $20,857 was slightly above
the national  average  of  $20,817  and significantly  ahead  of  that  for  the
southeast United States, which was $18,753. Real personal income in the State is
estimated  to  increase 4.5%  in  1994-95 and  4.2% in  1995-96.  By the  end of
1995-96, real personal income  per capita in the  State is projected to  average
4.5% higher than its 1993-94 level.
 
    EMPLOYMENT.   Since 1980, the State's job  creation rate is almost twice the
rate for the nation as a whole, and its growth rate in new non-agricultural jobs
is the fastest of the 11 most populous states, second only to California in  the
absolute  number of new jobs created. Contributing  to the State's rapid rate of
growth in employment and income is international trade. Since 1980, the  State's
unemployment  rate has generally  been below that  of the U.S.  In recent years,
however, as the State's economic growth has slowed from its previous highs,  the
State's  unemployment rate has  tracked above the  national average. The average
rate in Florida since  1980 has been  6.5% while the  national average is  7.1%.
According  to the U.S.  Department of Commerce, the  Florida Department of Labor
and  Employment  Security,  and   the  Florida  Consensus  Economic   Estimating
Conference  (together, the  "Organization"), the  State's unemployment  rate was
8.2% during  1992. As  of  January 1994,  the  Organization estimates  that  the
unemployment rate will be 6.1% for 1994-95 and 6.1% in 1995-96.
 
    The rate of job creation in Florida's manufacturing sector has exceeded that
of the U.S. From the beginning of 1980 through 1993, the State added over 50,000
new  manufacturing jobs,  an 11.7%  increase. During  the same  period, national
manufacturing employment declined ten out of  the fourteen years, for a loss  of
2,977,000 jobs.
 
    Total non-farm employment in Florida is expected to increase 3.6% in 1994-95
and  rise  3.3% in  1995-96.  Trade and  services,  the two  largest  sources of
employment in  the State,  account for  more  than half  of the  total  non-farm
employment.  Employment in the service sectors  should experience an increase of
5.4% in 1994-95 while growing 4.7% in 1995-96. Trade is expected to expand  3.1%
in  1995  and  3.2% in  1996.  The service  sector  is now  the  State's largest
employment category.
 
    CONSTRUCTION.  The State's economy has in the past been highly dependent  on
the   construction  industry   and  construction   related  manufacturing.  This
dependency has declined in recent  years and continues to do  so as a result  of
continued  diversification of the  State's economy. For  example, in 1980, total
contract construction employment  as a  share of total  non-farm employment  was
just over 7.0%, and in 1993 the share had edged
 
                                      A-1
<PAGE>
downward  to  5%. This  trend is  expected  to continue  as the  State's economy
continues to  diversify.  Florida,  nevertheless,  has  a  dynamic  construction
industry,  with single  and multi-family housing  starts accounting  for 8.5% of
total U.S. housing starts in  1993 while the State's  population is 5.3% of  the
U.S.  total population. Florida's housing starts  since 1980 have represented an
average of  11.0% of  the U.S.'s  total  annual starts,  and since  1980,  total
housing starts have averaged 156,450 a year.
 
    A  driving  force  behind the  State's  construction industry  has  been the
State's rapid rate  of population growth.  Although the State  currently is  the
fourth  most populous  state, its annual  population growth is  now projected to
decline as the number of people moving into the State is expected to hover  near
the  mid 250,000  range annually  throughout the  1990's. This  population trend
should provide fuel for business and home builders to keep construction activity
lively in Florida for some time to come. However, other factors do influence the
level of construction in the State. For example, federal tax reform in 1986  and
other  changes to the federal income tax code have eliminated tax deductions for
owners of more than two residential  real estate properties and have  lengthened
depreciation  schedules on investment and commercial properties. Economic growth
and existing supplies  of homes  also contribute  to the  level of  construction
activity in the State.
 
    Single  and multi-family housing starts in  1994-95 are projected to reach a
combined  level  of  118,000,  increasing   to  124,100  next  year.   Lingering
recessionary  effects on consumers and tight credit  are some of the reasons for
relatively slow core construction  activity, as well  as lingering effects  from
the 1986 tax reform legislation discussed above. Total construction expenditures
are forecasted to increase 6.6% this year and increase 7.5% next year.
 
    The   State  has  continuously   been  dependent  on   the  highly  cyclical
construction and  construction  related  manufacturing  industries.  While  that
dependency  has  decreased, the  State is  still  somewhat at  the mercy  of the
construction and construction related manufacturing industries. The construction
industry is driven to a great extent by the State's rapid growth in  population.
There  can be no  assurance that population growth  will continue throughout the
1990's in which case  there could be  an adverse impact  on the State's  economy
through  the loss of  construction and construction  related manufacturing jobs.
Also, recent increases  in interest rates  could significantly adversely  impact
the  financing of new construction within the State, thereby adversely impacting
unemployment and other economic factors within the State. In addition, available
commercial office space has tended  to remain high over  the past few years.  So
long  as this  glut of commercial  rental space continues,  construction of this
type of space will likely continue to remain slow.
 
    TOURISM.    Tourism  is  one  of  the  State's  most  important  industries.
Approximately  41.1 million tourists  visited the State in  1993, as reported by
the Florida Department of  Commerce. In terms of  business activities and  State
tax  revenues, tourists in Florida in  1993 represented an estimated 4.5 million
additional residents. Visitors to  the State tend to  arrive equally by air  and
car.  The State's tourism industry over the years has become more sophisticated,
attracting visitors  year-round  and, to  a  degree, reducing  its  seasonality.
Tourist arrivals are expected to increase by 5.0% this year, and 3.4% next year.
Tourist  arrivals to Florida by  air are expected to  increase by 9.2% this year
and 2.9% next year, while arrivals by  car are expected to rise 0.7% in  1994-95
and 4.0% in 1995-96. By the end of the State's current fiscal year, 42.1 million
domestic  and international tourists are expected  to have visited the State. In
1995-96 tourist arrivals should approximate 43.6 million.
 
    REVENUES AND EXPENSES.  Estimated  fiscal year 1994-95 General Revenue  plus
Working  Capital and  Budget Stabilization  funds available  to the  State total
$14,624.4 million, a  5.7% increase over  1993-94. This reflects  a transfer  of
$159.0  million in non-recurring revenue due to Hurricane Andrew, to a hurricane
relief trust fund. Of the total General Revenue plus Working Capital and  Budget
Stabilization  funds  available  to  the State,  $13,858.4  million  of  that is
Estimated Revenues (excluding the Hurricane Andrew impact), which represents  an
increase  of 7.9%  over the previous  year's Estimated  Revenues. With effective
General  Revenues   plus  Working   Capital   Fund  and   Budget   Stabilization
appropriations at $14,311.1 million, unencumbered reserves at the end of 1994-95
are  estimated at $313.3 million. Estimated  fiscal year 1995-96 General Revenue
plus Working Capital  and Budget Stabilization  funds available total  $15,145.9
million,  a  3.6%  increase over  1994-95.  The $14,647.2  million  in Estimated
Revenues represents  an increase  of  5.7% over  the previous  year's  Estimated
Revenues.
 
    In  fiscal  year  1993-94, approximately  66%  of the  State's  total direct
revenue to its three operating funds was derived from State taxes and fees, with
Federal grants and other special revenue accounting for the balance. State sales
and use tax, corporate income tax, intangible personal property tax and beverage
tax amounted to 66%, 8%, 4% and 4%, respectively, of total General Revenue Funds
available during fiscal 1993-94. In that same year, expenditures for  education,
health  and welfare, and  public safety amounted to  approximately 49%, 32%, and
12%, respectively, of total expenditures from the General Revenue Fund.
 
    The State's sales and use tax (6%) currently accounts for the State's single
largest source of tax receipts. Sightly less  than 10% of the State's sales  and
use  tax  is  designated  for  local  governments  and  is  distributed  to  the
 
                                      A-2
<PAGE>
respective counties  in  which  collected  for use  by  the  counties,  and  the
municipalities  therein. In addition to this distribution, local governments may
assess (by referendum) a 0.5% or a 1.0% discretionary sales surtax within  their
county.  Proceeds from  this local  option sales  tax are  earmarked for funding
local infrastructure  programs  and  acquiring land  for  public  recreation  or
conservation  or protection  of natural  resources as  provided under applicable
Florida law. Certain charter counties  have other additional taxing powers,  and
non-consolidated  counties with  a population  in excess  of 800,000  may levy a
local option sales tax to fund indigent health care. It alone cannot exceed 0.5%
and when combined  with the infrastructure  surtax cannot exceed  1.0%. For  the
fiscal  year ended June 30,  1994, sales and use  tax receipts (exclusive of the
tax on gasoline and  special fuels) totalled $10,012.5  million, an increase  of
6.9% over fiscal year 1992-93.
 
    The  second largest source of State tax  receipts is the tax on motor fuels.
However, these revenues are almost  entirely dedicated trust funds for  specific
purposes and are not included in the State's General Revenue Fund.
 
    The  State imposes an alcoholic beverage wholesale tax (excise tax) on beer,
wine, and  liquor. This  tax  is one  of the  State's  major tax  sources,  with
revenues totalling $439.8 million in fiscal year ending June 30, 1994. Alcoholic
beverage  tax receipts decreased about 1.0%  from the previous year's total. The
revenues collected from this tax are deposited into the State's General  Revenue
Fund.
 
    The  State imposes  a corporate  income tax.  All receipts  of the corporate
income tax are credited to the General  Revenue Fund. For the fiscal year  ended
June  30, 1994, receipts from this source  were $1,047.4 million, an increase of
23.7% from fiscal year 1992-93.
 
    The State  imposes a  documentary stamp  tax on  deeds and  other  documents
relating  to  realty,  corporate shares,  bonds,  certificates  of indebtedness,
promissory notes, wage assignments, and retail charge accounts. The  documentary
stamp  tax collections  totalled $775.0  million during  fiscal year  1993-94, a
21.3% increase from the previous fiscal year. Beginning in fiscal year  1992-93,
71.29% of these taxes is to be deposited to the General Revenue Fund.
 
    The  State  imposes  a gross  receipts  tax  on electric,  natural  gas, and
telecommunications services. All  gross receipts utilities  tax collections  are
credited  to the State's Public Education  Capital Outlay and Debt Service Trust
Fund. In fiscal year 1993-94, this amounted to $459.4 million.
 
    The State  imposes an  intangible personal  property tax  on stocks,  bonds,
including  bonds secured by liens in  Florida real property, notes, governmental
leaseholds, and certain other intangibles not secured by a lien on Florida  real
property.  The  annual  rate  of  tax  is  2  mils.  The  State  also  imposes a
non-recurring 2 mil tax on mortgages  and other obligations secured by liens  on
Florida  real  property.  In  fiscal  year  1993-94,  total  intangible personal
property tax collections  were $836.0 million,  a 6.7% increase  over the  prior
year. Of the tax proceeds, 66.5% is distributed to the General Revenue Fund.
 
    The  State's severance tax taxes oil, gas and sulphur production, as well as
the severance of phosphate rock and other solid minerals. Total collections from
severance taxes total $54.8 million during fiscal year 1993-94, down 15.0%  from
the  previous year. Currently 60%  of this amount is  transferred to the General
Revenue Fund.
 
    The State began  its own lottery  in 1988. State  law requires that  lottery
revenues  be  distributed  50.0% to  the  public  in prizes,  38.0%  for  use in
enhancing education,  and the  balance, 12.0%,  for costs  of administering  the
lottery.  Fiscal  year  1993-94  lottery ticket  sales  totalled  $2.15 billion,
providing education with approximately $816.2 million.
 
    DEBT-BALANCED BUDGET REQUIREMENT.  At the end of fiscal 1993,  approximately
$5.61  billion in principal amount of debt  secured by the full faith and credit
of the State was outstanding. In addition, since July 1, 1993, the State  issued
about $1.36 billion in principal amount of full faith and credit bonds.
 
    The  State Constitution  and statutes  mandate that  the State  budget, as a
whole, and each separate fund within the  State budget, be kept in balance  from
currently  available revenues each  fiscal year. If  the Governor or Comptroller
believe a deficit will occur in any State fund, by statute, he must certify  his
opinion to the Administrative Commission, which then is authorized to reduce all
State agency budgets and releases by a sufficient amount to prevent a deficit in
any  fund.  Additionally, the  State  Constitution prohibits  issuance  of State
obligations to fund State operations.
 
    LITIGATION.  Currently under litigation are several issues relating to State
actions or State taxes that put  at risk substantial amounts of General  Revenue
Fund  monies.  Accordingly, there  is  no assurance  that  any of  such matters,
individually or in the aggregate, will not have a material adverse affect on the
State's financial position.
 
    Florida law provides preferential tax  treatment to insurers who maintain  a
home  office in the State. Certain  insurers challenged the constitutionality of
this  tax  preference  and  sought  a  refund  of  taxes  paid.  Recently,   the
 
                                      A-3
<PAGE>
Florida  Supreme Court ruled in favor of  the State. This case and others, along
with pending refund claims, total about $150 million.
 
    Previously the State imposed a $295  fee on the issuance of certificates  of
title  for motor vehicles  previously titled outside  the State. Plaintiffs sued
the State  alleging that  this fee  violated  the Commerce  Clause of  the  U.S.
Constitution.  The Circuit  Court in  which the  case was  filed granted summary
judgment for the plaintiffs, enjoined further  collection of the impact fee  and
ordered  refunds to all those who have paid  the fee since the collection of the
fee went into effect. In the State's  appeal of the lower Court's decision,  the
Florida  Supreme  Court  ruled  that this  fee  was  unconstitutional  under the
Commerce Clause.  Thus,  the Supreme  Court  approved the  lower  court's  order
enjoining  further collection of the fee  and requiring refund of the previously
collected fees. The refund  exposure of the  State has been  estimated to be  in
excess of $100 million.
 
    The State maintains a bond rating of Aa, AA, and AA from Moody's, Standard &
Poor's,  and  Fitch, respectively,  on the  majority  of its  general obligation
bonds, although  the rating  of a  particular series  of revenue  bonds  relates
primarily  to the  project, facility,  or other  revenue source  from which such
series derives  funds  for  repayment.  While these  ratings  and  some  of  the
information  presented above indicate that the State is in satisfactory economic
health, there can be no assurance that  there will not be a decline in  economic
conditions or that particular Bonds purchased by the Trust will not be adversely
affected by any such changes.
 
    The  sources for the information presented above include official statements
and financial statements  of the  State of Florida.  While the  Sponsor has  not
independently  verified this information,  it has no reason  to believe that the
information is not correct in all material respects.
 
FLORIDA TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The following tables show the approximate taxable estimated current  returns
for  individuals  that are  equivalent to  tax-exempt estimated  current returns
under  published  1995  marginal  Federal  tax  rates.  The  tables  incorporate
increased  tax  rates  for higher-income  taxpayers  that were  included  in the
Revenue Reconciliation Act of 1993. The tables illustrate what you would have to
earn on taxable investments to equal the tax-exempt estimated current return for
your income tax bracket. A taxpayer's marginal tax rate is affected by both  his
taxable  income and  his adjusted gross  income. Locate your  adjusted gross and
your taxable  income  (which  is  your adjusted  gross  income  reduced  by  any
deductions  and  exemptions), then  locate your  tax bracket  based on  joint or
single tax  filing. Read  across  to the  equivalent taxable  estimated  current
return you would need to match the tax-free income.

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

ECONOMIC FACTORS--NEW YORK
 
    The  Portfolio of the New York Traditional Trust includes obligations issued
by New York State (the "State"), by its various public bodies (the  "Agencies"),
and/or  by other entities  located within the  State, including the  City of New
York (the "City").
 
    Some of the more significant events and conditions relating to the financial
situation in New York are summarized  below. This section provides only a  brief
summary of the complex factors affecting the financial situation in New York and
is  derived  from  sources that  are  generally  available to  investors  and is
believed to  be  accurate.  It is  based  in  part on  Official  Statements  and
prospectuses issued by, and on other information reported by the State, the City
and the Agencies in connection with the issuance of their respective securities.
 
    There  can  be no  assurance that  current or  future statewide  or regional
economic difficulties, and  the resulting  impact on State  or local  government
finances  generally,  will not  adversely affect  the market  value of  New York
Municipal Obligations  held in  the portfolio  of the  Trust or  the ability  of
particular  obligors to make timely payments of debt service on (or relating to)
those obligations.
 
    (1) THE STATE: The State has historically been one of the wealthiest  states
in  the nation. For  decades, however, the  State economy has  grown more slowly
than that  of the  nation as  a whole,  gradually eroding  the State's  relative
economic  affluence.  Statewide,  urban  centers  have  experienced  significant
changes involving migration of the more affluent to the suburbs and an influx of
generally less affluent residents. Regionally,  the older Northeast cities  have
suffered because of the relative success that the South and the West have had in
attracting  people  and  business.  The  City  has  also  had  to  face  greater
competition  as  other  major  cities  have  developed  financial  and  business
capabilities  which  make  them  less  dependent  on  the  specialized  services
traditionally available almost exclusively in the City.
 
    The State has  for many years  had a very  high state and  local tax  burden
relative to other states. The burden of State and local taxation, in combination
with  the many other causes of regional economic dislocation, has contributed to
the decisions of  some businesses and  individuals to relocate  outside, or  not
locate within, the State.
 
    SLOWDOWN  OF REGIONAL ECONOMY.  A national recession  commenced in mid-1990.
The downturn  continued  throughout the  State's  1990-91 fiscal  year  and  was
followed  by a period of weak economic growth during the 1991 calendar year. For
calendar year 1992,  the national economy  continued to recover,  although at  a
rate  below all  post-war recoveries. For  calendar year 1993,  the economy grew
faster than in 1992,  but still at  a very moderate rate,  as compared to  other
recoveries.  Moderate economic growth continued in calendar year 1994. The State
has projected the rate of economic growth  to slow within New York during  1995,
as  the expansion of  the national economy  moderates. Economic recovery started
considerably later in the State than in the nation as a whole due in part to the
significant retrenchment  in  the  banking and  financial  services  industries,
downsizing  by several major corporations, cutbacks  in defense spending, and an
oversupply of office buildings.  Many uncertainties exist  in forecasts of  both
the  national and State economies  and there can be  no assurance that the State
economy will perform at  a level sufficient to  meet the State's projections  of
receipts and disbursements.
 
    1995-96  FISCAL YEAR.   The Governor issued a  proposed Executive Budget for
the 1995-96  fiscal year  (the "Proposed  Budget") on  February 1,  1995,  which
projected  a  balanced  general fund  and  receipts and  disbursements  of $32.5
billion and  $32.4  billion,  respectively.  As  of  May  29,  1995,  the  State
legislature  had  not yet  enacted,  nor had  the  Governor and  the legislature
reached an agreement on, the budget for the 1995-96 fiscal year which  commenced
on April 1, 1995. The delay in the enactment of the budget may negatively affect
certain proposed actions and reduce projected savings.
 
    The  Proposed Budget and the 1995-96  Financial Plan provide for the closing
of  a  projected  $4.7  billion  budget  gap  in  the  1995-96  fiscal  year  by
cost-containment  savings in social welfare  programs, savings from State agency
restructurings, freezing  the level  of some  categories of  local aid  and  new
revenue measures.
 
    The  State's proposed budget and the 1995-96 Plan may be impacted negatively
by uncertainties relating to  the economy and  tax collections, although  recent
signs  of improvement in the national economy could lead to short-term increases
in State receipts.
 
    1994-1995 FISCAL YEAR.   The State Legislature  enacted the State's  1994-95
fiscal year budget on June 7, 1994, more than two months after the start of that
fiscal  year. As of February  1, 1995, the updated  1994-95 State Financial Plan
(the "Plan") projected total  general fund receipts  and disbursements of  $33.3
billion and $33.5 billion, respectively, representing reductions in receipts and
disbursements of $1 billion and $743 million,
 
                                      B-1
<PAGE>
respectively,  from  the  amount  set  forth in  the  1994-95  budget.  The Plan
projected for a General Fund balance of approximately $157 million at the  close
of the 1994-95 fiscal year.
 
    1993-94  FISCAL  YEAR.   The State  ended  the 1993-94  fiscal year  with an
operating surplus of approximately $1.0 billion.
 
    FUTURE FISCAL YEARS. There can be no assurance that the State will not  face
substantial  potential budget  gaps in the  future resulting  from a significant
disparity between tax revenues  projected from a  lower recurring receipts  base
and  the  spending required  to maintain  State programs  at current  levels. To
address  any  potential  budgetary  imbalance,  the  State  may  need  to   take
significant actions to align recurring receipts and disbursements.
 
    INDEBTEDNESS.  As of  March 31,  1994, the  total amount  of long-term State
general obligation debt authorized but unissued stood at $2.0 billion. As of the
same date, the State had approximately $5.4 billion in general obligation  bonds
including $224 million of Bond Anticipation Notes outstanding.
 
    The  State  originally projected  that its  borrowings for  capital purposes
during the State's 1994-95 fiscal year would consist of $374 million in  general
obligation  bonds  and  bond  anticipation notes  and  $140  million  in general
obligation commercial paper. The Legislature  has authorized the issuance of  up
to $69 million in certificates of participation in pools of leases for equipment
and  real property to be utilized by State agencies. Through March 15, 1995, the
State had  issued in  excess of  $590 million  of its  general obligation  bonds
(including  $430  million  of refunding  bonds).  The projections  of  the State
regarding its borrowings  for any fiscal  year are subject  to change if  actual
receipts fall short of State projections or if other circumstances require.
 
    In  June  1990,  legislation  was  enacted  creating  the  "New  York  Local
Government  Assistance  Corporation"  ("LGAC"),  a  public  benefit  corporation
empowered  to  issue long-term  obligations to  fund  certain payments  to local
governments traditionally funded through the State's annual seasonal  borrowing.
As  of March 31, 1994, LGAC has issued its bonds to provide net proceeds of $4.5
billion. The LGAC was authorized to provide net proceeds of $315 million, during
the State's 1994-95 fiscal year. The LGAC issued $347 million of bonds on  March
1, 1995 providing the authorized net proceeds.
 
    Financing  of capital programs  by other public authorities  of the State is
also  obtained   from   lease-purchase  and   contractual-obligation   financing
arrangements,  the debt service for which  is paid from State appropriations. As
of March 31, 1994, there were $16.6 billion of such other financing arrangements
outstanding and additional financings of  this nature by public authorities  are
projected  to total  $2.4 billion during  the 1994-95 fiscal  year. In addition,
certain agencies had issued and outstanding approximately $7.3 billion of "moral
obligation financings" as of March 31, 1994, which are to be repaid from project
revenues. While there has never been a  default on moral obligation debt of  the
State, the State would be required to make up any shortfall in debt service.
 
    RATINGS.   The $850 million in TRANS issued  by the State in April 1993 were
rated SP-1-Plus by S&P and MIG-1 by Moody's which represent the highest  ratings
given  by such agencies and the first time the State's TRANS have received these
ratings since  its May  1989 TRANS  issuance. Both  agencies cited  the  State's
improved  fiscal position as a significant factor  in the upgrading of the April
1993 TRANS.
 
    Moody's rating  of  the State's  general  obligation  bonds stood  at  A  on
February  28, 1994,  and S&P's  rating stood  at A-  with a  positive outlook on
February 28, 1994,  an improvement  from S&P's  stable outlook  from April  1993
through  February 1994  and negative  outlook prior  to April  1993. Previously,
Moody's lowered its rating to A on June 6, 1990, its rating having been A1 since
May 27, 1986. S&P  lowered its rating from  A to A- on  January 13, 1992.  S&P's
previous ratings were A from March 1990 to January 1992, AA- from August 1987 to
March 1990 and A+ from November 1982 to August 1987.
 
    Moody's  maintained  its  A  rating  and  S&P  continued  its  A-  rating in
connection with the State's issuance of  $537 million of its general  obligation
bonds in March 1995.
 
    (2)  THE CITY  AND THE  MUNICIPAL ASSISTANCE  CORPORATION ("MAC"):  The City
accounts for approximately 40%  of the State's  population and personal  income,
and the City's financial health affects the State in numerous ways.
 
    In  response to the City's fiscal crisis in 1975, the State took a number of
steps to assist the City in returning to fiscal stability. Among other  actions,
the State Legislature (i) created MAC to assist with long-term financing for the
City's  short-term debt and  other cash requirements and  (ii) created the State
Financial Control Board (the "Control Board")  to review and approve the  City's
budgets  and City four-year  financial plans (the financial  plans also apply to
certain City-related public agencies (the "Covered Organizations")).
 
    In  recent  years,  the  rate  of   economic  growth  in  the  City   slowed
substantially  as the City's economy entered a recession. While by some measures
the City's economy  may have begun  to recover, a  number of factors,  including
poor  performance  by the  City's financial  services  companies, may  prevent a
significant improvement in the City's economy and may in fact negatively  impact
upon  the  City's  finances  by  reducing  tax  receipts.  The  City Comptroller
 
                                      B-2
<PAGE>
has issued reports concluding  that the recession of  the City's economy may  be
ending,  but there is little prospect of any significant improvement in the near
term.
 
    FISCAL YEAR 1996 AND  THE 1995-1998 FINANCIAL PLAN.   On February 14,  1995,
the  Mayor released his  preliminary $30.5 billion budget  for fiscal year 1996,
which included $2.7 billion of deficit reduction measures. The Mayor is  seeking
a  $1.2 billion reduction in mandated welfare and Medicaid expenditures from the
State, a $569 million reduction in  expenditures by city agencies and the  Board
of  Education budget, $600  million in personnel  related savings partly through
the elimination of 15,000 jobs within 18 months, and other measures.
 
    The 1995-1998  Financial  Plan (the  "Plan"),  which was  submitted  to  the
Control  Board on February 23,  1995, projected budget gaps  of $3.2 billion and
$3.8 billion for fiscal years 1997 and 1998, respectively. The City  Comptroller
warned  on March 7, 1995 that the budget gap for fiscal year 1996 could increase
by $500 million to as much as $3.2 billion. The Control Board reported on  March
17,  1995 that the proposed budget for  fiscal year 1996 relies heavily on risky
assumptions such as $600  million in savings to  be negotiated with City  unions
and $1.4 billion in savings dependent on State legislative approval.
 
    The  City successfully  negotiated concessions  with a  number of  unions in
order to ensure that the fiscal year 1995 budget remained in balance. The  Mayor
has indicated that to avoid additional lay-offs, higher than the number referred
to above, reductions will be necessary in the benefit plans of City employees to
close the budget gaps for fiscal years 1996 and thereafter. Union leadership has
publicly opposed such "givebacks". With respect to fiscal year 1995 the City was
also  successful in obtaining additional funds  and relief from certain mandated
expenditures from the State for  various programs, including Medicaid.  However,
the  amount of gap closing measures requiring State action set forth in the Plan
is well in excess of proposed assistance to the City outlined in the  Governor's
Proposed Budget.
 
    The  Mayor has directed City agencies to identify an additional $300 million
in cuts for fiscal  year 1996 because  of anticipated shortfalls  of as much  as
$500  million in State aid and budgetary actions. An extended delay by the State
in adopting its  1995-96 fiscal  year budget  would negatively  impact upon  the
City's  financial condition  and ability to  close budget gaps  for fiscal years
1996 and thereafter.
 
    Given the foregoing factors,  there can be no  assurance that the City  will
continue  to maintain  a balanced  budget, or  that it  can maintain  a balanced
budget without additional tax or other  revenue increases or reductions in  City
services, which could adversely affect the City's economic base.
 
    Pursuant  to State law, the City prepares a four-year annual financial plan,
which is reviewed and revised on a quarterly basis and which includes the City's
capital, revenue and  expense projections. The  City is required  to submit  its
financial  plans to review bodies, including the Control Board. If the City were
to experience certain adverse financial circumstances, including the  occurrence
or  the  substantial likelihood  and imminence  of the  occurrence of  an annual
operating deficit of more than $100 million or the loss of access to the  public
credit   markets  to   satisfy  the   City's  capital   and  seasonal  financial
requirements, the  Control Board  would be  required by  State law  to  exercise
certain  powers,  including prior  approval  of City  financial  plans, proposed
borrowings and certain contracts.
 
    The City depends  on the  State for  State aid both  to enable  the City  to
balance  its budget and to meet its  cash requirements. If the State experiences
revenue shortfalls  or  spending increases  beyond  its projections  during  its
1995-96  fiscal  year or  subsequent years,  such  developments could  result in
reductions in projected  State aid to  the City.  In addition, there  can be  no
assurance  that State  budgets in  the 1996-97  or future  fiscal years  will be
adopted by the April  1 statutory deadline  and that there  will not be  adverse
effects  on the City's cash flow and additional City expenditures as a result of
such delays.
 
    The City projections set forth in the Plan are based on various  assumptions
and  contingencies which are uncertain and which may not materialize. Changes in
major assumptions could significantly affect  the City's ability to balance  its
budget  as required by State law and to  meet its annual cash flow and financing
requirements. Such  assumptions  and contingencies  include  the timing  of  any
regional and local economic recovery, the absence of wage increases in excess of
the  increases assumed  in its financial  plan, employment  growth, provision of
State and Federal aid and mandate  relief, State legislative approval of  future
State budgets, levels of education expenditures as may be required by State law,
adoption  of future City budgets  by the New York  City Council, and approval by
the Governor or the State Legislature and the cooperation of MAC with respect to
various other actions proposed in the Plan.
 
    The City's ability to maintain a  balanced operating budget is dependant  on
whether  it  can implement  necessary service  and personnel  reduction programs
successfully. As discussed above, the City must identify additional  expenditure
reductions  and revenue sources to achieve balanced operating budgets for fiscal
years 1996
 
                                      B-3
<PAGE>
and thereafter. Any such  proposed expenditure reductions  will be difficult  to
implement  because  of their  size  and the  substantial  expenditure reductions
already imposed on City operations in the past two years.
 
    Attaining a balanced  budget is also  dependent upon the  City's ability  to
market  its securities  successfully in  the public  credit markets.  The City's
financing program  for  fiscal  years 1995  through  1998  contemplates  capital
spending  of $16.4  billion, which  will be  financed through  issuance of $10.7
billion of  general obligation  bonds and  the balance  through Water  Authority
Revenue  Bonds  and  Covered  Organization  obligations,  and  will  be utilized
primarily to reconstruct and rehabilitate the City's infrastructure and physical
assets and  to make  capital investments.  A significant  portion of  such  bond
financing  is used to reimburse the City's general fund for capital expenditures
already incurred.  In addition,  the City  issues revenue  and tax  anticipation
notes  to  finance  its seasonal  working  capital requirements.  The  terms and
success of projected  public sales of  City general obligation  bonds and  notes
will  be subject to prevailing market conditions at the time of the sale, and no
assurance can be given that the credit markets will absorb the projected amounts
of public bond and note sales.  In addition, future developments concerning  the
City  and public  discussion of such  developments, the  City's future financial
needs and  other issues  may  affect the  market  for outstanding  City  general
obligation  bonds  and  notes. If  the  City  were unable  to  sell  its general
obligation bonds  and notes,  it would  be prevented  from meeting  its  planned
operating and capital expenditures.
 
    FISCAL YEAR 1995.  New York City adopted its fiscal year 1995 budget on June
21,  1994, which provided for spending of  $31.6 billion and closed a budget gap
of $2.3 billion.  However, following adoption  of the fiscal  year 1995  budget,
additional  unexpected  budget  gaps totaling  approximately  $2.0  billion were
identified. The widening of  the budget gap for  fiscal year 1995 resulted  from
shortfalls  in tax revenues  and State and  federal aid. The  Mayor and the City
Council were unable to reach agreement on additional cuts proposed by the  Mayor
in October 1994. The City Council passed its own budget cut proposal in November
1994.  The Mayor vetoed the City Council  version, the City Council overrode his
veto and the Mayor implemented his original plan. A state court held in December
1994 that  neither budget  cut proposal  could be  implemented. The  Mayor  then
elected not to spend certain funds in order to keep the budget in balance.
 
    FISCAL  YEARS  1990  THROUGH 1994.    The City  achieved  balanced operating
results as reported in  accordance with GAAP for  its fiscal years 1990  through
1994.  The City was  required to close  substantial budget gaps  in these fiscal
years to maintain balanced operating results.
 
    The City is a defendant in a significant number of lawsuits. Such litigation
includes, but is not limited to,  actions commenced and claims asserted  against
the  City arising out  of alleged constitutional  violations, torts, breaches of
contracts, and other violations of  law and condemnation proceedings. While  the
ultimate  outcome and fiscal impact,  if any, on the  proceedings and claims are
not currently predictable, adverse determinations in certain of them might  have
a  material adverse effect  upon the City's  ability to carry  out its financial
plan. As of June 30, 1994, the City estimated its potential future liability  to
be $2.6 billion.
 
    On  January  30, 1995,  Robert L.  Schulz and  other defendants  commenced a
federal district court action seeking among other matters to cancel the issuance
on January 31, 1995 of $659 million of City bonds. While the federal courts have
rejected requests for  temporary restraining orders  and expedited appeals,  the
case  is still pending. The City has indicated that it believes the action to be
without merit as it relates to the City, but there can be no assurance as to the
outcome of the litigation and an adverse  ruling or the granting of a  permanent
injunction  would have a  negative impact on the  City's financial condition and
its ability to fund its operations.
 
    RATINGS.  As of the  date of this prospectus,  Moody's rating of the  City's
general  obligation  bonds stood  at Baa1  and  S&P's rating  stood at  BBB+. On
February 11, 1991,  Moody's had  lowered its rating  from A.  S&P's lowered  its
rating  from A-  on July  10, 1995  after placing  the City  on "negative credit
watch" in January 1995.
 
    On March 13, 1995,  Moody's confirmed its Baa1  rating in connection with  a
scheduled  March  1995 sale  of $795  million of  the City's  general obligation
bonds.
 
    In dropping  the City's  rating in  July 1995,  S&P's cited  the  "sluggish"
economy  and the poor  outlook for job growth,  as well as  the continued use of
"one-time measures" to close budget gaps. The lowered rating could increase  the
City's borrowing costs by forcing it to offer higher interest rates on its bonds
thereby adding further pressures to the City's budget problems. In addition, the
lowered  rating may prevent certain  institutional investors from purchasing the
City's bonds reducing demand  for future offerings, which  could also force  the
City to increase interest rates on its bonds.
 
    On  October 12, 1993, Moody's increased its rating of the City's issuance of
$650 million of Tax  Anticipation Notes ("TANs") to  MIG-1 from MIG-2. Prior  to
that  date, on May 9,  1990, Moody's revised downward  its rating on outstanding
City revenue anticipation notes from MIG-1  to MIG-2 and rated the $900  million
Notes then being
 
                                      B-4
<PAGE>
sold  MIG-2. S&P's rating of the October  1993 TANS issue increased to SP-1 from
SP-2. Prior to that date, on April 29, 1991, S&P revised downward its rating  on
City revenue anticipation notes from SP-1 to SP-2.
 
    As  of December 31, 1994, the City  and MAC had, respectively, $22.5 billion
and $4.1 billion of outstanding net long-term indebtedness.
 
    (3) THE STATE AGENCIES: Certain Agencies of the State have faced substantial
financial difficulties which could adversely affect the ability of such Agencies
to make payments  of interest  on, and  principal amounts  of, their  respective
bonds.  The  difficulties  have in  certain  instances caused  the  State (under
so-called  "moral  obligation"  provisions   which  are  non-binding   statutory
provisions  for State  appropriations to  maintain various  debt service reserve
funds) to appropriate funds on behalf of the Agencies. Moreover, it is  expected
that  the  problems  faced by  these  Agencies  will continue  and  will require
increasing amounts of State assistance in future years. Failure of the State  to
appropriate  necessary amounts or to take  other action to permit those Agencies
having financial  difficulties  to meet  their  obligations could  result  in  a
default by one or more of the Agencies. Such default, if it were to occur, would
be  likely to have a  significant adverse effect on  investor confidence in, and
therefore the  market  price of,  obligations  of the  defaulting  Agencies.  In
addition,  any default in payment on any  general obligation of any Agency whose
bonds contain a moral obligation provision could constitute a failure of certain
conditions that must be satisfied in connection with Federal guarantees of  City
and  MAC obligations  and could thus  jeopardize the  City's long-term financing
plans.
 
    As of  September 30,  1993,  the State  reported  that there  were  eighteen
Agencies that each had outstanding debt of $100 million or more and an aggregate
of  $63.5  billion  of  outstanding debt,  some  of  which  was state-supported,
state-related debt.
 
    (4) STATE LITIGATION: The State is a defendant in numerous legal proceedings
pertaining to  matters incidental  to the  performance of  routine  governmental
operations.  Such litigation  includes, but is  not limited  to, claims asserted
against the State  arising from  alleged torts, alleged  breaches of  contracts,
condemnation proceedings and other alleged violations of State and Federal laws.
Included in the State's outstanding litigation are a number of cases challenging
the  constitutionality  or  the  adequacy  and  effectiveness  of  a  variety of
significant social  welfare  programs  primarily involving  the  State's  mental
hygiene  programs. Adverse judgments in these  matters generally could result in
injunctive relief coupled with prospective  changes in patient care which  could
require substantial increased financing of the litigated programs in the future.
 
    The  State  is  also engaged  in  a  variety of  claims  wherein significant
monetary damages are sought. Actions  commenced by several Indian nations  claim
that  significant amounts of land were unconstitutionally taken from the Indians
in violation  of  various treaties  and  agreements during  the  eighteenth  and
nineteenth  centuries. The claimants seek  recovery of approximately six million
acres of land as well as compensatory and punitive damages.
 
    The  State  has   entered  into  a   settlement  agreement  with   Delaware,
Massachusetts  and all other parties with respect  to STATE OF DELAWARE V. STATE
OF NEW  YORK,  an action  by  Delaware and  other  states to  recover  unclaimed
property  from New York-based brokers, which has escheated to the State pursuant
to its ABANDONED  PROPERTY LAW. Annual  payments under this  settlement will  be
made  through the  State's 2002-03  fiscal year  in amounts  not exceeding $48.4
million in any fiscal year subsequent to the State's 1994-95 fiscal year.
 
    In SCHULZ V.  STATE OF  NEW YORK, commenced  May 24,  1993 ("SCHULZ  1993"),
petitioners have challenged the constitutionality of mass transportation bonding
programs   of  the  New  York  State  Thruway  Authority  and  the  Metropolitan
Transportation Authority. On  May 24,  1993, the Supreme  Court, Albany  County,
temporarily enjoined the State from implementing those bonding programs.
 
    Petitioners in SCHULZ asserted that issuance of bonds by the two Authorities
is  subject to approval  by statewide referendum. By  decision dated October 21,
1993, the  Appellate  Division, Third  Department,  affirmed the  order  of  the
Supreme  Court, Albany County, granting the State's motion for summary judgment,
dismissing the complaint and vacating  the temporary restraining order. On  June
30,  1994, the Court of Appeals, the State's highest court, upheld the decisions
of the Supreme Court  and Appellate Division in  SCHULZ, Plaintiffs' motion  for
reargument  was denied by  the Court of  Appeals on September  1, 1994 and their
writ of certiorari to the U.S. Supreme Court was denied on January 23, 1995.
 
    Adverse developments in the foregoing  proceedings or new proceedings  could
adversely affect the financial condition of the State in the future.
 
    (5)  OTHER MUNICIPALITIES: Certain  localities in addition  to New York City
could  have  financial  problems  leading  to  requests  for  additional   State
assistance.  The potential impact on the State  of such actions by localities is
not included in projections  of State receipts and  expenditures in the  State's
1994-95 fiscal years.
 
                                      B-5
<PAGE>
    Fiscal  difficulties experienced by the City of Yonkers ("Yonkers") resulted
in the creation  of the Financial  Control Board  for the City  of Yonkers  (the
"Yonkers  Board")  by the  State  in 1984.  The  Yonkers Board  is  charged with
oversight of the fiscal affairs of Yonkers. Future actions taken by the Governor
or the State Legislature to assist  Yonkers could result in allocation of  State
resources in amounts that cannot yet be determined.
 
    Municipalities  and school districts have  engaged in substantial short-term
and long-term borrowings. In 1992, the  total indebtedness of all localities  in
the  State was approximately $35.2  billion, of which $19.5  billion was debt of
New York  City (excluding  $5.9 billion  in MAC  debt). State  law requires  the
Comptroller  to review and make recommendations  concerning the budgets of those
local government units other than New York City authorized by State law to issue
debt to  finance deficits  during  the period  that  such deficit  financing  is
outstanding.   Seventeen  localities  had  outstanding  indebtedness  for  state
financing at the close of their fiscal year ending in 1992.
 
    Certain proposed Federal  expenditure reductions  could reduce,  or in  some
cases  eliminate, Federal funding  of some local  programs and accordingly might
impose substantial increased expenditure requirements on affected localities. If
the State, New York City or any of the Agencies were to suffer serious financial
difficulties jeopardizing their respective access to the public credit  markets,
the  marketability of  notes and  bonds issued  by localities  within the State,
including notes  or bonds  in the  New York  Insured Trust,  could be  adversely
affected. Localities also face anticipated and potential problems resulting from
certain  pending litigation, judicial decisions, and long-range economic trends.
The longer-range potential  problems of declining  urban population,  increasing
expenditures,  and other economic  trends could adversely  affect localities and
require increasing State assistance in the future.
 
    (6) OTHER ISSUERS OF NEW YORK  MUNICIPAL OBLIGATIONS. There are a number  of
other  agencies, instrumentalities and political  subdivisions of the State that
issue Municipal Obligations, some  of which may  be conduit revenue  obligations
payable  from payments  from private  borrowers. These  entities are  subject to
various economic  risks  and  uncertainties,  and  the  credit  quality  of  the
securities  issued  by them  may vary  considerably from  the credit  quality of
obligations backed by the full faith and credit of the State.

NEW YORK TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The following tables show the approximate taxable estimated current  returns
for  individuals  that are  equivalent to  tax-exempt estimated  current returns
under combined Federal,  state and  local taxes, using  published 1995  marginal
Federal tax rates and marginal state and local tax rates currently available and
scheduled  to  be in  effect.  The tables  incorporate  increased tax  rates for
higher-income taxpayers that were included in the Revenue Reconciliation Act  of
1993.  For cases  in which  two state  or local  brackets fall  within a federal
bracket, the higher state or local bracket is combined with the federal bracket.
The combined local, state and Federal  tax brackets shown reflect the fact  that
state  and local tax payments are currently deductible for Federal tax purposes.
The tables illustrate  what you  would have to  earn on  taxable investments  to
equal  the tax-exempt  estimated current return  for your income  tax bracket. A
taxpayer's marginal tax  rate is  affected by both  his taxable  income and  his
adjusted gross income. Locate your adjusted gross and your taxable income (which
is  your adjusted gross  income reduced by any  deductions and exemptions), then
locate your tax bracket based on joint or single tax filing. Read across to  the
equivalent taxable estimated current return you would need to match the tax-free
income.

- ------------------
 
      1  The table reflects the effect of the limitations on itemized deductions
and the  deduction for  personal exemptions.  They were  designed to  phase  out
certain  benefits  of  these  deductions  for  higher  income  taxpayers.  These
limitations, in effect,  raise the  marginal Federal tax  rate to  approximately
44.0  percent for taxpayers filing a joint  return and entitled to four personal
exemptions and  to approximately  41.0  percent for  taxpayers filing  a  single
return entitled to only one personal exemption. These limitations are subject to
certain maximums, which depend on the number of exemptions claimed and the total
amount  of the  taxpayer's itemized deductions.  For example,  the limitation on
itemized deductions will  not cause  a taxpayer  to lose  more than  80% of  his
allowable  itemized deductions, with certain exceptions. The table also reflects
the New York  State supplemental  income tax based  upon a  taxpayer's New  York
State taxable income and New York State adjusted gross income. This supplemental
tax  results in  an increased  marginal state  income tax  rate to  the extent a
taxpayer's New  York State  adjusted gross  income ranges  between $100,000  and
$150,000.  The table does not,  however, reflect the amendments  to the New York
State income tax law that imposes  limitations on the deductibility of  itemized
deductions.  The  application  of  the New  York  State  limitation  on itemized
deductions may result  in a higher  combined Federal, State  and local tax  rate
than  indicated  in  the  table.  The table  assumes  for  this  purpose  that a
taxpayer's New  York State  adjusted income  equals his  Federal adjusted  gross
income.
 
      2 Federal tax rate reverts to 36.0% after the 80% cap on the limitation on
itemized deductions has been met.
 
      3 Federal tax rate reverts to 39.6% after the 80% cap on the limitation on
itemized deductions has been met.

                                OHIO DISCLOSURE
 
ECONOMIC FACTORS--OHIO
 
    As  described  above, the  Trust will  invest substantially  all of  its net
assets in  securities  issued  by  or  on  behalf  of  (or  in  certificates  of
participation  in lease  purchase obligations of)  the State  of Ohio, political
subdivisions of the State, or agencies or instrumentalities of the State or  its
political subdivisions (Ohio Obligations). The Trust is therefore susceptible to
general or particular economic, political, or regulatory factors that may affect
issuers  of Ohio Obligations. The following information constitutes only a brief
summary of  some of  the  many complex  factors that  may  have an  effect.  The
information  does not apply to "conduit"  obligations on which the public issuer
itself has  no  financial  responsibility.  This  information  is  derived  from
official  statements of certain Ohio issuers  published in connection with their
issuance of securities  and from  other publicly available  information, and  is
believed to be accurate. No independent verification has been made of any of the
following information.
 
    Generally,  the  creditworthiness of  Ohio Obligations  of local  issuers is
unrelated to that  of obligations  of the  State itself,  and the  State has  no
responsibility  to  make  payments  on those  local  obligations.  There  may be
specific factors that at particular times apply in connection with investment in
particular Ohio Obligations or in those obligations of particular Ohio  issuers.
It  is possible that the investment may be in particular Ohio Obligations, or in
those of  particular issuers,  as to  which those  factors apply.  However,  the
information  below is intended only as a general summary, and is not intended as
a discussion of any specific factors  that may affect any particular  obligation
or issuer.
 
    The timely payment of principal of and interest on Ohio Obligations has been
guaranteed  by  bond insurance  purchased  by the  issuers,  the Trust  or other
parties. Those Ohio Obligations may not be subject to the factors referred to in
this section of the Prospectus.
 
    Ohio is the seventh most populous state. The 1990 Census count of 10,847,000
indicated a 0.5% population increase from 1980. The Census estimate for 1993  is
11,091,000.
 
    While  diversifying more into the service and other non-manufacturing areas,
the Ohio  economy continues  to  rely in  part  on durable  goods  manufacturing
largely concentrated in motor vehicles and equipment, steel, rubber products and
household  appliances. As a result, general  economic activity, as in many other
industrially-developed states,  tends to  be more  cyclical than  in some  other
states  and in the nation as a whole. Agriculture is an important segment of the
economy, with over half  the State's area devoted  to farming and  approximately
15% of total employment in agribusiness.
 
    In  prior years, the State's overall unemployment rate was commonly somewhat
higher than the national figure. For example, the reported 1990 average  monthly
State rate was 5.7%, compared to the 5.5% national figure. However, for the last
four  years the State rates  were below the national  rates (5.5% versus 6.1% in
1994). The unemployment rate and its effects vary among geographic areas of  the
State.
 
    There  can  be no  assurance that  future  national, regional  or state-wide
economic difficulties, and  the resulting  impact on State  or local  government
finances  generally,  will  not  adversely  affect  the  market  value  of  Ohio
Obligations held in the Trust portfolio or the ability of particular obligors to
make timely payments of  debt service on (or  lease payments relating to)  those
obligations.
 
    The  State operates on the basis of a fiscal biennium for its appropriations
and expenditures, and  is precluded by  law from ending  its July 1  to June  30
fiscal year "FY" or fiscal biennium in a deficit position. Most State operations
are  financed through the General Revenue  Fund "GRF", for which personal income
and sales-use taxes are  the major sources. Growth  and depletion of GRF  ending
fund balances show a consistent pattern related to national economic conditions,
with  the ending FY  balance reduced during less  favorable and increased during
more favorable economic periods. The State has well-established procedures  for,
and  has timely taken, necessary actions to ensure resource/expenditure balances
during less favorable  economic periods. Those  procedures included general  and
selected reductions in appropriations spending.
 
    Key  biennium-ending fund balances  at June 30, 1989  were $475.1 million in
the GRF and $353  million in the  Budget Stabilization Fund  ("BSF", a cash  and
budgetary  management  fund). June  30, 1991  ending  fund balances  were $135.3
million (GRF) and $300 million (BSF).
 
   
    The next  biennium,  1992-93,  presented  significant  challenges  to  State
finances,  successfully  addressed.  To  allow time  to  resolve  certain budget
differences, an interim appropriations act  was enacted effective July 1,  1991;
it  included GRF  debt service  and lease  rental appropriations  for the entire
biennium, while continuing most  other appropriations for  a month. Pursuant  to
the general appropriations act for the entire biennium, passed on July 11, 1991,
$200 million was transfered from the BSF to the GRF in FY 1992.
    
 
                                      C-1
<PAGE>
   
    Based  on the updated results and forecast in the course of that FY, both in
light of  a  continuing  uncertain  nationwide  economic  situation,  there  was
projected,  and then timely addressed, an FY 1992 imbalance in GRF resources and
expenditures. In response, the  Governor ordered most  State agencies to  reduce
GRF  spending in the last six months of FY 1992 by a total of approximately $184
million; the  $100.4 million  BSF balance  and additional  amounts from  certain
other  funds were transferred  late in the  FY to the  GRF; and adjustments were
made in the timing of certain tax payments.
    
 
    A significant GRF shortfall (approximately $520 million) was then  projected
for  FY 1993.  It was  addressed by  appropriate legislative  and administrative
actions, including the Governor's ordering $300 million in selected GRF spending
reductions and subsequent executive and legislative action (a combination of tax
revisions and additional spending reductions). The June 30, 1993 ending GRF fund
balance was  approximately  $111 million,  of  which, as  a  first step  to  BSF
replenishment, $21 million was deposited in the BSF.
 
   
    None  of the spending  reductions were applied  to appropriations needed for
debt service on or lease rentals relating to any State obligations.
    
 
   
    The 1994-95 biennium presented a  more affirmative financial picture.  Based
on  June 30, 1994 balances, an additional $260 million was deposited in the BSF.
The biennium ended June 30, 1995 with a GRF ending fund balance of $928 million,
of which $535.2 million has been transferred into the BSF (which had a  November
21, 1995 balance of over $828 million).
    
 
   
    The  GRF appropriations act for the 1995-96  biennium was passed on June 28,
1995 and promptly signed (after selective vetoes) by the Governor. All necessary
GRF appropriations  for  State  debt  service and  lease  rental  payments  then
projected  for the biennium  were included in  that act. In  accordance with the
appropriations act,  the  significant June  30,  1995 GRF  fund  balance,  after
leaving  in the GRF  an unreserved and  undesignated balance of  $70 million has
been transferred to the  BSF and other funds  including school assistance  funds
and,  in  anticipation of  possible federal  program  changes, a  human services
stabilization fund.
    
 
    The State's incurrence or  assumption of debt without  a vote of the  people
is,   with  limited  exceptions,  prohibited  by  current  State  constitutional
provisions. The State may  incur debt, limited in  amount to $750,000, to  cover
casual  deficits  or failures  in  revenues or  to  meet expenses  not otherwise
provided for. The Constitution expressly  precludes the State from assuming  the
debts of any local government or corporation. An exception is made in both cases
for  any debt incurred  to repel invasion, suppress  insurrection, or defend the
State in war.
 
   
    By 14 constitutional amendments, the last adopted in 1995, Ohio voters  have
authorized  the incurrence of State  debt and the pledge  of taxes or excises to
its payment. At December 2, 1995, $778 million (excluding certain highway  bonds
payable  primarily from highway  use charges) of this  debt will be outstanding.
The only such  State debt  at that  date still  authorized to  be incurred  were
portions  of the  highway bonds, and  the following:  (a) up to  $100 million of
obligations for coal research and development may be outstanding at any one time
($45.3  million  outstanding);  (b)  $360  million  of  obligations   previously
authorized  for local infrastructure improvements, no  more than $120 million of
which may to be  issued in any calendar  year ($685.4 million outstanding);  and
(c)  up to $200  million in general  obligation bonds for  parks, recreation and
natural resource  purposes which  may  be outstanding  at  any one  time  ($47.2
million  outstanding, with  no more  than $50  million to  be issued  in any one
year).
    
 
   
    The electors  approved  in November  1995  a constitutional  amendment  that
extends  the local infrastructure  bond program (authorizing  an additional $1.2
billion of State full faith  and credit ogligations to  be issued over 10  years
for the purpose) and authorizes additional highway bonds (expected to be payable
primarily  from  highway use  receipts). The  latter  supersedes the  prior $500
million highway  obligaton  authorization, and  authorizes  not more  than  $1.2
billion  to be  outstanding at  any time and  not more  than $220  million to be
issued in a fiscal year.
    
 
   
    Common resolutions are pending in both  houses of the General Assembly  that
would  submit a  constitutional amendment relating  to certain  other aspects of
State debt. The proposal  would authorize, among other  things, the issuance  of
State general obligation debt for a variety of purposes with debt service on all
State  general obligation debt and GRF-supported obligations not to exceed 5% of
the preceding fiscal year's GRF expenditures.
    
 
   
    The Constitution  also  authorizes the  issuance  of State  obligations  for
certain  purposes, the owners of which do not  have the right to have excises or
taxes levied to pay debt service. Those special obligations include  obligations
issued by the Ohio Public Facilities Commission and the Ohio Building Authority,
and certain obligations issued by the State Treasurer, over $4.5 billion of will
be outstanding awaiting delivery at December 2, 1995.
    
 
    A  1990  constitutional  amendment authorizes  greater  State  and political
subdivision participation (including financing) in the provision of housing. The
General  Assembly  may  for  that  purpose  authorize  the  issuance  of   State
obligations secured by a pledge of all or such portion as it authorizes of State
revenues  or  receipts, (but  not  by a  pledge of  the  State's full  faith and
credit).
 
                                      C-2
<PAGE>
    A 1994 constitutional amendment pledges the full faith and credit and taxing
power of  the State  to meeting  certain guarantees  under the  State's  tuition
credit  program  which provides  for the  purchase of  tuition credits,  for the
benefit of State residents, guaranteed to cover a specified amount when  applied
to  the cost  of higher education  tuition. (1965  constitutional provision that
authorized student loan guarantees payable from available State moneys has never
been implemented, apart from a "guarantee fund" approach funded essentially from
program revenues.)
 
    The House  has adopted  a resolution  that would  submit to  the electors  a
constitutional  amendment prohibiting the  General Assembly from  imposing a new
tax or increasing an existing tax unless aproved by a three-fifths vote of  each
house  or by  a majority vote  of the  electors. It cannot  be predicted whether
required Senate concurrence to submission will be received.
 
    State and local agencies  issue obligations that  are payable from  revenues
from  or  relating  to certain  facilities  (but  not from  taxes).  By judicial
interpretation,  these  obligations   are  not   "debt"  within   constitutional
provisions.  In general, payment obligations  under lease-purchase agreements of
Ohio public agencies (in which certificates of participation may be issued)  are
limited  in duration to the agency's fiscal  period, and are renewable only upon
appropriations being made available for the subsequent fiscal period.
 
   
    Local school districts in Ohio receive a major portion (state-wide aggregate
in the  range of  44% in  recent years)  of their  operating moneys  from  State
subsidies,  but are dependent on local property taxes, and in 120 districts from
voter-authorized income  taxes,  for  significant  portions  of  their  budgets.
Litigation,  similar  to  that  in  other  states,  is  pending  questioning the
constitutionality of Ohio's system of school funding. The trial court  concluded
that   aspects  of  the  system   (including  basic  operating  assistance)  are
unconstitutional, and  ordered  the State  to  provide  for and  fund  a  system
complying  with the Ohio Constitution. The State appealed and a court of appeals
reversed the  trial  court's findings  for  plaintiff districts.  The  plaintiff
coalition  has filed  an appeal  of the  court of  appeals decision  to the Ohio
Supreme Court. A small number of the State's 612 local school districts have  in
any  year  required special  assistance to  avoid  year-end deficits.  A current
program  provides  for  school  district  cash  need  borrowing  directly   from
commercial  lenders, with diversion of  State subsidy distributions to repayment
if needed. Recent borrowings  under this program totalled  $94.5 million for  27
districts  (including $75  million for  one) in  FY 1993,  $41.1 million  for 28
districts in FY 1994, and $71.1 million for 29 districts in FY 1995.
    
 
    Ohio's 943 incorporated cities and  villages rely primarily on property  and
municipal  income taxes for their operations. With other subdivisions, they also
receive local government support and  property tax relief moneys distributed  by
the  State. For those few municipalities that on occasion have faced significant
financial problems,  there  are statutory  procedures  for a  joint  State/local
commission to monitor the municipality's fiscal affairs and for development of a
financial  plan to eliminate deficits and  cure any defaults. Since inception in
1979, these procedures have been  applied to 23 cities  and villages; for 18  of
them the fiscal situation was resolved and the procedures terminated.
 
    At  present  the State  itself does  not levy  ad valorem  taxes on  real or
tangible personal property. Those taxes are levied by political subdivisions and
other local taxing districts. The Constitution  has since 1934 limited to 1%  of
true  value in  money the  amount of  the aggregate  levy (including  a levy for
unvoted general obligations) of property taxes by all overlapping  subdivisions,
without  a vote of the  electors or a municipal  charter provision, and statutes
limit the amount of the aggregate levy to 10 mills per $1 of assessed  valuation
(commonly  referred to as the  "ten-mill limitation"). Voted general obligations
of subdivisions are payable from property taxes that are unlimited as to  amount
or rate.
 
OHIO TAXABLE ESTIMATED CURRENT RETURN TABLE
 
    The  following tables show the approximate taxable estimated current returns
for individuals  that are  equivalent to  tax-exempt estimated  current  returns
under  combined Federal and  state taxes, using  published 1994 marginal Federal
tax rates and marginal state tax  rates currently available and scheduled to  be
in  effect.  The  tables  incorporate  increased  tax  rates  for  higher-income
taxpayers that were  included in  the Revenue  Reconciliation Act  of 1993.  For
cases  in which more than one state  bracket falls within a Federal bracket, the
highest state bracket is combined with  the Federal bracket. The combined  state
and  Federal tax  brackets shown  reflect the fact  that state  tax payments are
currently deductible for Federal  tax purposes. The  tables illustrate what  you
would  have to  earn on  taxable investments  to equal  the tax-exempt estimated
current return for your  income tax bracket. A  taxpayer's marginal tax rate  is
affected  by both his taxable income and  his adjusted gross income. Locate your
adjusted gross and  your taxable  income (which  is your  adjusted gross  income
reduced by any deductions and exemptions), then locate your tax bracket based on
joint  or single  tax filing.  Read across  to the  equivalent taxable estimated
current return you would need to match the tax-free income.

</TABLE>
 
- ------------------
 
      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.

John Nuveen & Co. Incorporated
333 W. Wacker Drive
Chicago, IL  60606

RE: Nuveen Tax-Exempt Unit Trust, Series 838

Gentlemen:

    This is in response to your requests regarding the above-
captioned fund which consists of separate underlying unit investment trusts
(the "trusts"), SEC file # 33-64005.

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

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

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

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

Very truly yours,

STANDARD & POOR'S, A DIVISION OF THE MCGRAW-HILL COMPANIES

Agreements with respect to those series.  We have also examined such 
pertinent records and documents and matters of law as we have deemed 
necessary including (but not limited to) the Trust Indenture and Agreement 
relating to Nuveen Tax-Exempt Unit Trust, Series 838.

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

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

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

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

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

<PAGE>

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

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

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

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

    (viii)  In the case of Trusts for which MBIA Insurance Corporation ("MBIA")
insurance with respect to each of the Bonds deposited therein has been obtained 
by the Depositor or the issuer or underwriter of the Bonds, we have examined 
the form of MBIA's policy or several policies of insurance (the "Policies") 
which have been delivered to the Trustee.  Assuming issuance of Policies in such
form, in our opinion, any amounts paid under said Policies representing maturing
interest on defaulted obligations held by the Trustee will be excludable from 
Federal gross income if, and to the same extent as, such interest would have 
been so excludable if paid by the respective issuer, provided that, at the time 
such policies are purchased, the amounts paid for such policies are reasonable, 
customary and consistent with the reasonable expectation that the issuer of the 
bonds, rather than the insurer, will pay debt service on the bonds.  Paragraph 
(ii) of this opinion is accordingly applicable to Policy proceeds representing 
maturing interest.
<PAGE>

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

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

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

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

<PAGE>

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

    "The Revenue Reconciliation Act of 1993" (the "Tax Act") subjects tax-exempt
bonds to the market discount rules of the Code effective for bonds purchased
after April 30, 1993.  In general, market discount is the amount (if any) by
which the stated redemption price at maturity exceeds an investor's purchase
price (except to the extent that such difference, if any, is attributable to
original issue discount not yet accrued) subject to a statutory de minimis rule.
Market discount can arise based on the price a Trust pays for Bonds or the price
a Unitholder pays for his or her Units.  Under the Tax Act, accretion of market
discount is taxable as ordinary income; under prior law, the accretion had been 
treated as capital gain.  Market discount that accretes while a Trust holds a 
Bond would be recognized as ordinary income by the Unitholders when principal 
payments are received on the Bond, upon sale or at redemption (including early 
redemption), or upon the sale or redemption of his or her Units, unless a 
Unitholder elects to include market discount in taxable income as it accrues.
     
    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-64005) relating to the Units referred
to above and to the use of our name and to the reference to our firm in said
Registration Statement and in the related Prospectus.

Respectfully submitted,

Nuveen Tax-Exempt Unit Trust, Series 838
Florida Insured Trust 221
John Nuveen & Co. Incorporated
333 W. Wacker Drive
Chicago, Illinois  60606

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

        Re:   
             Florida Insured Trust 221

Gentlemen:

    We have acted as special Florida counsel to Nuveen Tax-Exempt Unit Trust, 
Series 838 including the above-captioned trust (the "Fund") in connection 
with the issuance by the Fund of units of fractional undivided interests in 
the Fund (the "Units").  In that connection, you have requested our opinion as 
to the application of Florida state and local taxes to the Trust (as hereinafter
defined) and to investors who purchase units in the Trust.

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

    (a)  The Fund has been organized under a Trust Indenture and Agreement
between John Nuveen & Co., Incorporated (the "Depositor") and The Chase 
Manhattan Bank, N.A. (the "Trustee").

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

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

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

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

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

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

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

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

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


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

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

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

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

<PAGE>

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

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

    (a)  "Florida Code" shall mean the Florida Income Tax Code, Chapter 220,
Florida Statutes, as amended.  In the Florida Income Tax Code, Chapter 220, 
Florida Statutes, the Florida Legistature has adopted, retroactively to 
January 1, 1995, the Internal Revenue Code of 1986, as amended and in effect 
on January 1, 1995, as the Internal Revenue Code under which a Corporate 
Unitholder must compute its income for purposes of Florida corporate income 
taxation.

    (b)  "Code" shall mean the Internal Revenue Code of 1986, as
amended and in effect on January 1, 1995.

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

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

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

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

<PAGE>

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

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

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-64005) and to the reference to our
firm in such Registration Statement and the Prospectus included
therein. In giving such consent, we do not thereby admit that we are within 
the category of persons whose consent is required by Section 7 of the 
Securities Act of 1933, as amended, and the rules and regulations thereunder.

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


Very truly yours,

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

The Chase Manhattan Bank, N.A.,
as Trustee of Nuveen Tax-Exempt Unit Trust,
Series 838
770 Broadway
New York, NY  10003

Re:  
    New York Insured Trust 244
     
     

Dear Sirs:

    We have acted as special counsel, with respect to New York State and New
York City tax matters, to the above Trusts(s) ("New York Trust(s)") of Nuveen
Tax-Exempt Unit Trust, Series 838 (the "Fund") concerning a
Registration Statement (No. 33-64005) on Form S-6 under the Securities Act of
1933, as amended (the "Registration Statement"), covering the issuance by the
New York Trusts(s) of units of fractional undivided interest in the New York
Trust(s)( "Units").
    We have not been furnished with a copy of the Registration Statement or
the prospectus, which is a part of the Registration Statement, relating to the
issuance by the New York Trust(s) of the Units.  However, John Nuveen & Co.
Incorporated has authorized us to assume that the proposed offer and sale of
the Units will be carried out in that same manner and upon the same terms and
conditions as that described in the prospectus for the Nuveen Tax Exempt Unit
Trust, Insured Series 193, dated May 19, 1989, which we were furnished and did
examine. In the case of a Fund which contains a New York Insured Trust or
New York Intermediate Insured Trust, we also were not furnished the
Insurance Agreement (the "Policy") between the Municipal Bond Investors
Assurance Corporation (the "Insurer"), the Depositor and the Trustee.
However, John Nuveen & Co. Incorporated has authorized us to
assume that the Policy will be implemented at the closing of the Trust and
be in substance and form materially similiar to the Policy applicable to
New York Insured Trust 108, which we were furnished and did examine.

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

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

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

    (A)  Interest on obligations issued by New York State, a political
subdivision thereof, Puerto Rico, the Virgin Islands, Guam, the Northern
Mariana Islands, or other possessions of the United States within the meaning
of Section 103(c) of the Internal Revenue Code of 1986, as amended,
("Obligations") which would be exempt from New York State or New York City
personal income tax if directly received by a Unitholder, will retain its
status as tax-exempt interest when received by a New York Trust and
distributed to such Unitholder;

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

<PAGE>


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

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

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

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

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

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

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

    We are further of the opinion that, for purposes of the New York State and
New York City franchise tax on corporations, Unitholders which are
subject to such tax will be required to include in their entire net income any
interest or gains distributed to them in respect of obligations of any state
or political subdivision thereof, including New York.  No opinion is rendered
on the includability in entire net income of interest distributed to such
Unitholders in respect of obligations issued by Puerto Rico, the Virgin
Islands, Guam, the Northern Mariana Islands or other possessions of the
United States within the meaning of Section 103(c) of the Internal Revenue
Code of 1986, as amended.

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

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

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

Very truly yours,



EDWARDS & ANGELL

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

The Chase Manhattan Bank, N.A.
770 Broadway
New York, New York 10003

RE:  Nuveen Tax-Exempt Unit Trust, Series 838
      
     Ohio Insured Trust 130

Gentlemen:

    You have requested our opinion as to the Ohio tax aspects of the above-
captioned Trust(s) (the "Ohio Trust(s)"), which is(are) part of the
Nuveen Tax-Exempt Unit Trust --  Series 838 (the "Fund").  We understand
that the Fund is organized under the Trust Indenture and Agreement, dated the
date hereof, between John Nuveen & Co. Incorporated, as Depositor, and The
Chase Manhattan Bank, N.A., as Trustee.  We further understand that (i)
the Fund will issue Units of fractional undivided interests in several state
trusts, including the Ohio Trust(s), (ii) the Units will be purchased by
various investors ("Unitholders"), (iii) each Unit of the Ohio Trust(s)
represents a fractional undivided interest in the principal and net income of
the Ohio Trust(s) in the ratio of ten Units for each $1,000 of principal
amount of the obligations initially acquired by the Ohio Trust(s), and (iv)
each state trust will be administered as a distinct entity with separate
certificates, investments, expenses, books and records.

    In addition, we understand that (i) the Ohio Trust(s) is(are) comprised
primarily of interest-bearing obligations issued by or on behalf of the State
of Ohio, political subdivisions thereof, or agencies or instrumentalities
thereof ("Ohio Obligations"), or by the governments of Puerto Rico, the Virgin
Islands, the Northern Mariana Islands or Guam ("Territorial Obligations")
(collectively, "Obligations"), (ii) at all times at least fifty percent of the
total assets of the Ohio Trust(s) will consist of Ohio Obligations, or similar
obligations of other states or their subdivisions, and (iii) distributions of
interest received by the Ohio Trust(s) will be made semi-annually unless the
Unitholder elects otherwise.  We further understand that, based on the opinion
of bond counsel with respect to each issue of Ohio Obligations held or to be
held by the Ohio Trust, rendered on the date of issuance thereof, interest on
each such issue is excluded from gross income for federal income tax purposes
under Section 103(a) of the Internal Revenue Code of 1986, as amended ("Code"),
or other provisions of federal law, provided that with respect to certain Ohio
and Territorial Obligations, certain representations are accurate and certain
covenants are satisfied.

 
    We understand that Chapman and Cutler has rendered an opinion that
for federal income tax purposes the Ohio Trust(s) will not be taxable as (an)
association(s) but will be governed by the provisions of subchapter J
(relating to trusts) of Chapter 1 of the Code; each Unitholder will be
considered the owner of a pro rata portion of the Unitholder's respective
Ohio Trust under Section 676(a) of the Code; the Ohio Trust(s) will not be
subject to federal income tax; each Unitholder will be considered to have
received his pro rata share of interest on the underlying bonds in the
Unitholder's respective Ohio Trust when it is received by such Ohio Trust;
and each Unitholder will have a taxable event when the Unitholder's respective
Ohio Trust disposes of an underlying obligation (whether by sale, exchange,
redemption, or payment at maturity) or when the Unitholder redeems or sells
his Units.
 
    Based on the foregoing and upon an examination of such other documents and
an investigation of such other matters of law as we have deemed necessary, we
are of the opinion that under existing Ohio law:

    1.   The Ohio Trust(s) is(are) not taxable as (a) corporation(s) or
otherwise for purposes of the Ohio personal income tax, Ohio school district
income taxes, the Ohio corporation franchise tax, or the Ohio dealers in
intangibles tax.

    2.   Income of the Ohio Trust(s) will be treated as the income of the
Unitholders for purposes of the Ohio personal income tax and municipal and 
school district income taxes in Ohio and the Ohio corporation franchise tax 
in proportion to the respective interest therein of each Unitholder.

    3.   Interest on Obligations held by the Ohio Trust(s) is exempt from the
Ohio personal income tax, and municipal and school district income taxes in
Ohio, and is excluded from the net income base of the Ohio corporation 
franchise tax when distributed or deemed distributed to Unitholders.

    4.   Proceeds paid under insurance policies, if any, to the Trustee of
the Ohio Trust(s) representing maturing interest on defaulted obligations held
by the Ohio Trust(s) that is excluded from gross income for federal income tax
purposes will be exempt from the Ohio personal income tax and municipal and 
school district income taxes in Ohio and the net income base of the Ohio 
corporation franchise tax.

     5.  Gains and losses realized on the sale, exchange or other disposition
by the Ohio Trust(s) of Ohio Obligations are excluded in determining adjusted
gross and taxable income for purposes of the Ohio personal income tax, and 
municipal and school district income taxes in Ohio, and are excluded from the 
net income base of the Ohio corporation franchise tax when distributed or 
deemed distributed to Unitholders.


    We have not examined any of the obligations to be deposited in the Ohio
Trust(s) and express no opinion as to whether such obligations, interest
thereon, or gain from the sale or other disposition thereof would in fact be
exempt from any federal or Ohio taxes if such obligations were held, or such
interest or gain were received, directly by the Unitholders.

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (No. 33-64005) relating to the Units referred to
above, and to the reference to our firm as special Ohio tax counsel in said
Registration Statement and in the Prospectus contained therein.

Respectfully submitted,



SQUIRE, SANDERS & DEMPSEY

                 Nuveen Tax-Exempt Unit Trust, Series 838
                               File No. 33-64005


    The Prospectus and the Indenture filed with Amendment No. 1 of the
Registration Statement on Form S-6 have been revised to reflect information
regarding the execution of the Indenture and the deposit of bonds on 12/01/95,
and to set forth certain statistical data based thereon.  In addition, there 
are a number of other changes from the Prospectus as originally filed to which
reference is made, including the increase in the size of the Fund, a
corresponding increase in the number of Units and a change in the individual
trusts constituting the Fund.  All references to the Units, prices and related
statistical data will apply to each trust of the Fund and the Units thereof
individually.

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