             Prospectus, Part I 8,207 Units Dated: November 29, 1999

             NOTE: Part I of this Prospectus may not be distributed
                         unless accompanied by Part II.

      This Prospectus  consists of two parts. The first part contains a "Summary
of Essential Financial  Information" on the reverse hereof as of August 31, 1999
and a summary of additional  specific  information  including  "Special  Factors
Concerning  the  Portfolio"  and  audited  financial  statements  of the  Trust,
including the related bond  portfolio,  as of July 31, 1999.  The second part of
this  Prospectus  contains a general  summary of the Trust and "Special  Factors
Affecting New York."


      The Trust is a unit  investment  trust formed for the purpose of obtaining
tax-exempt  interest  income  through  investment  in  a  diversified,   insured
portfolio  of long-term  bonds,  issued by or on behalf of the State of New York
and counties,  municipalities,  authorities or political subdivisions thereof or
issued by certain  United States  territories  or  possessions  and their public
authorities (the "Bonds"). See Part II under "The Trust." The Bonds deposited in
the portfolio of the Trust are sometimes referred to herein as the "Securities."
Insurance  guaranteeing  the payment of principal and interest on the Securities
while in the Trust has been  obtained by the Trust from the Insurer as set forth
in Part II under "Insurance on the Bonds." Such insurance does not guarantee the
market  value of the  Securities  or the Units  offered  hereby.  The payment of
interest and the  preservation  of principal are, of course,  dependent upon the
continuing  ability of the  issuers  of the Bonds and any other  insurer to meet
their  obligations.  As a result of the  insurance  on the Bonds,  the Units are
rated "AAA" by Standard & Poor's Ratings Services, a Division of The McGraw-Hill
Companies ("Standard & Poor's").


      In the  opinion  of special  counsel  for the  Sponsors  as of the Date of
Deposit, interest on the Bonds that is excludable from federal gross income when
received by the Trust will be  excludable  from the federal  gross income of the
Unit holders and with certain exceptions, interest income to the Unit holders is
generally  exempt  from all New York  State  and New York City  personal  income
taxes.  Capital  gains,  if any,  are  subject  to tax.  See Part II under  "Tax
Status."


      Offering.  The  initial  public  offering  of Units in the  Trust has been
completed.  The Units offered hereby are issued and outstanding Units which have
been  acquired  by the  Sponsors  either by  purchase  from the Trustee of Units
tendered for redemption or in the secondary market. See Part II under "Rights of
Unit Holders --  Redemption  -- Purchase by the  Sponsors of Units  Tendered for
Redemption"  and  "Public  Offering -- Market for Units." The price at which the
Units  offered  hereby  were  acquired  was not less than the  redemption  price
determined  as described  herein.  See Part II under  "Rights of Unit Holders --
Redemption -- Computation of Redemption Price per Unit."

      The Public Offering Price of the Units is based on the aggregate bid price
of the Securities in the Trust divided by the number of Units outstanding,  plus
a sales charge  determined on the basis of the  maturities of the  Securities in
the  Trust.  See  "Public  Offering  --  Offering  Price"  in  Part  II of  this
Prospectus.

      Market for Units. The Sponsors,  although they are not obligated to do so,
intend to  maintain a  secondary  market for the Units at prices  based upon the
aggregate bid price of the Securities in the Trust plus accrued  interest to the
date of settlement, as more fully described in Part II under "Public Offering --
Market for Units." If such a market is not maintained, a Unit holder may be able
to  dispose  of his Units  only  through  redemption  at prices  based  upon the
aggregate  bid price of the  underlying  Securities.  The purchase  price of the
Securities  in the  Trust,  if  they  were  available  for  direct  purchase  by
investors,  would not include the sales charges  included in the Public Offering
Price of the Units.

      Investors   should  retain  both  Parts  of  this  Prospectus  for  future
reference.

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION OR ANY STATE  SECURITIES  COMMISSION NOR HAS THE SECURITIES
AND  EXCHANGE  COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

- -------------------

1.     The sales charge is determined  based on the maturities of the underlying
       securities in the portfolio.  See "Public  Offering -- Offering Price" in
       Part II of this Prospectus.


2.     Plus  accrued  interest  to  September  3,  1999,  the  expected  date of
       settlement, of $2.60 monthly and $15.78 semi-annually.


3.     Based solely upon the bid side  evaluations of the portfolio  securities.
       Upon tender for  redemption,  the price to be paid will  include  accrued
       interest  as  described  in Part II  under  "Rights  of Unit  Holders  --
       Redemption -- Computation of Redemption Price per Unit."

4.     Estimated  Current  Return is  calculated  by dividing the  estimated net
       annual  interest  income received in cash per Unit by the Public Offering
       Price.  Interest  income  per Unit  will vary  with  changes  in fees and
       expenses  of the  Trustee  and the  Evaluator,  and with the  redemption,
       maturity,  exchange  or  sale  of  Securities.  This  calculation,  which
       includes cash income accrual only, does not include discount accretion on
       original  issue  discount  bonds  or on  zero  coupon  bonds  or  premium
       amortization  on bonds  purchased  at a  premium.  See "Tax  Status"  and
       "Estimated Current Return and Estimated Long-Term Return to Unit Holders"
       in Part II of this Prospectus.

5.     Estimated  Long-Term  Return is  calculated by using a formula that takes
       into  account  the  yields   (including   accretion   of  discounts   and
       amortization  of  premiums)  of  the  individual  Bonds  in  the  Trust's
       portfolio, weighted to reflect the market value and time to maturity (or,
       in certain  cases,  to  earlier  call date) of such  Bonds,  adjusted  to
       reflect the Public Offering Price  (including  sales charge and expenses)
       per Unit. See "Estimated Current Return and Estimated Long-Term Return to
       Unit Holders" in Part II of this Prospectus.

       Portfolio Information
       ---------------------


       On July 31,  1999,  the bid  side  valuation  of  27.1% of the  aggregate
principal amount of Bonds in the Portfolio for this Trust was at a discount from
par and 72.9%  was at a  premium  over  par.  See Note (B) to  "Tax-Exempt  Bond
Portfolio" for information concerning call and redemption features of the Bonds.


       Special Factors Concerning the Portfolio
       ----------------------------------------


       On July 31, 1999,  the Portfolio  consisted of six issues of Bonds issued
by  entities  located  in New  York or  certain  United  States  territories  or
possessions.  The following information is being supplied to inform Unit Holders
of circumstances affecting the Trust. 37.9% of the aggregate principal amount of
the  Bonds  in the  Portfolio  are  payable  from  appropriations.  62.1% of the
aggregate  principal  amount of the Bonds in the  Portfolio are payable from the
income of specific projects or authorities and are not supported by the issuers'
power to levy taxes.

       Although  income  to pay such  Bonds  may be  derived  from more than one
source,  the  primary  sources of such  income,  the  number of issues  (and the
related dollar  weighted  percentage of such issues)  deriving  income from such
sources and the purpose of issue are as follows:  Appropriations,  two  (37.9%);
Revenue:  Health Care, two (48.0%);  Higher Education,  one (12.0%) and Housing,
one (2.1%).  The Trust is deemed to be  concentrated in the  Appropriations  and
Health Care Bonds  categories.1 Four issues,  constituting 85.9% of the Bonds in
the  Portfolio,  are original issue  discount  bonds.  Three issues (50.1%) were
rated AAA and two issues (27.1%) were rated BBB+ by Standard & Poor's; one issue
(22.8%) was rated A3 by Moody's Investors Service, Inc. ("Moody's).2  Subsequent
to such date, such ratings may have changed.  See "Tax-Exempt  Bond  Portfolio."
For a more detailed discussion,  it is recommended that Unit Holders consult the
official statements for each Security in the Portfolio of the Trust.

       Interest  income on the Bonds contained in the Trust Portfolio is, in the
opinion of bond counsel to the issuing governmental authorities, excludable from
gross income under the Internal Revenue Code of 1986, as amended. See "The Trust
- -- Portfolio" in Part II of this Prospectus.

       Tax Status
       ----------

       Interest on the Bonds in the Trust  Portfolio  is  generally  exempt from
federal income taxes. It is also generally  exempt from New York State and local
personal  income  taxes.  Bond counsel to the issuing  governmental  authorities
delivered their opinions confirming the tax-exempt status of the interest on the
dates of issuance of the Bonds.  See "The Trust - Portfolio"  in Part II of this
Prospectus.

       In the opinion of counsel to the  sponsor,  the Trust is not treated as a
separate taxable entity,  and instead the Unit Holders will be treated as owning
the Trust's assets and as receiving the Trust's income.

       Gain or loss  realized on a sale,  maturity or redemption of the Bonds by
the Trust or on a sale or  redemption  of a Unit by a Unit  Holder must be taken
into  account  for  federal,  state and local  income tax  purposes.  It will be
capital  gain or loss if the Units are held as  capital  assets and will be long
term if the Units  (and the  Bonds)  have been held for more than one year.  The
gain or loss on  disposition  does  not  include  any  amount  received  that is
attributable  to accrued  interest or earned  original issue discount  (which is
generally treated as tax-exempt  interest) or any accrued market discount (which
is generally  treated as ordinary  income).  Long-term capital gains realized by
noncorporate  taxpayers  are taxed at a maximum  federal  income tax rate of 20%
while  ordinary  income and short-term  capital gains  received by  noncorporate
taxpayers will be taxed at regular federal income tax rates of up to 39.6%.



- -------------------
       1A Trust is considered to be "concentrated"  in a particular  category or
issuer when the Bonds in that category or of that issuer  constitute 25% or more
of the  aggregate  face  amount  of the  Portfolio.  See "The  Trust --  General
Considerations" in Part II of this Prospectus.

       2For the meanings of ratings,  see  "Description of Bond Ratings" in Part
II of this Prospectus.

INDEPENDENT AUDITOR'S REPORT




The Sponsors,  Trustee and Unit Holders of Empire State Municipal
     Exempt Trust, Guaranteed Series 121:


We have  audited  the  accompanying  statement  of net  assets of  Empire  State
Municipal  Exempt Trust,  Guaranteed  Series 121,  including the tax-exempt bond
portfolio,  as of July 31, 1999,  and the related  statements of operations  and
changes in net assets for the years ended July 31,  1999,  1998 and 1997.  These
financial  statements are the responsibility of the Trustee.  Our responsibility
is to express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1999, by correspondence with the
Trustee.  An audit also includes  assessing the accounting  principles  used and
significant  estimates  made by the Trustee,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position of Empire State Municipal Exempt
Trust,  Guaranteed  Series  121 as of July  31,  1999,  and the  results  of its
operations and changes in net assets for the years ended July 31, 1999, 1998 and
1997 in conformity with generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS
                       ===================================




The Trust is a unit investment trust formed under the Investment  Company Act of
1940 for the purpose of obtaining  tax-exempt interest income through investment
in a fixed  insured  portfolio of  long-term  bonds,  issued  primarily by or on
behalf of the State of New York and  counties,  municipalities,  authorities  or
political subdivisions thereof.

The Bank of New York (the "Trustee") has custody of and  responsibility  for the
accounting records and financial  statements of the Trust and is responsible for
establishing and maintaining a system of internal control.

The Trustee is also  responsible  for all  estimates  of expenses  and  accruals
reflected  in the  Trust's  financial  statements.  The  accompanying  financial
statements   have  been   adjusted   to  record  the   unrealized   appreciation
(depreciation)  of investments and to record interest income and expenses on the
accrual basis.


NOTE 1 - ACCOUNTING POLICIES
- ----------------------------

           Securities
           ----------

                Securities  are stated at bid side market value as determined by
an independent  outside evaluator.  Securities  transactions are recorded on the
trade  date.  The  difference  between  cost and market  value is  reflected  as
unrealized appreciation  (depreciation) of investments.  Realized gains (losses)
from securities  transactions are determined on the basis of average cost of the
securities sold or redeemed.

           Taxes on income
           ---------------

                The Trust is not subject to taxes on income and, accordingly, no
provision has been made.

           Termination of Trust
           --------------------

                The  mandatory  termination  date of the Trust is  December  31,
2044.  If the value of the Trust falls below  $2,000,000  or 20% of the value of
the Trust as of the date of deposit, whichever is lower, the Trust is subject to
termination as specified in the Trust Agreement.

           Organizational costs
           --------------------

                Organizational  costs are being  amortized over a period of five
years using the straight-line method.

           Value per unit
           --------------

                Included  in value  per  unit is  undistributed  net  investment
income per unit.  This  represents  income  earned and accrued to each unit less
amounts  distributed to the Unit Holder. The last income distribution dates were
July 1 and  June 1,  1999 for  Unit  Holders  electing  monthly  or  semi-annual
distributions,  respectively,  resulting  in a higher  value  per unit for those
electing semi-annual distributions than those electing monthly distributions.

                       NOTES TO TAX-EXEMPT BOND PORTFOLIO


(A)     A description  of the rating  symbols and their  meanings  appears under
        "Description of Bond Ratings" in Part II of this Prospectus. Ratings are
        by Standard & Poor's  except for those  indicated  by (*),  which are by
        Moody's. Certain bond ratings have changed since the Date of Deposit, at
        which time all such  bonds  were rated A or better by either  Standard &
        Poor's or Moody's.

(B)     Bonds may be redeemable prior to maturity from a sinking fund (mandatory
        partial redemption) (S.F.) or at the stated optional call (at the option
        of the issuer)  (Opt.) or by  refunding.  Certain bonds in the portfolio
        may be  redeemed  earlier  than  dates  shown in whole or in part  under
        certain unusual or extraordinary circumstances as specified in the terms
        and provisions of such bonds.

             Prospectus, Part I 8,624 Units Dated: November 29, 1999

             NOTE: Part I of this Prospectus may not be distributed
                         unless accompanied by Part II.

      This Prospectus  consists of two parts. The first part contains a "Summary
of Essential Financial  Information" on the reverse hereof as of August 31, 1999
and a summary of additional  specific  information  including  "Special  Factors
Concerning  the  Portfolio"  and  audited  financial  statements  of the  Trust,
including the related bond  portfolio,  as of July 31, 1999.  The second part of
this  Prospectus  contains a general  summary of the Trust and "Special  Factors
Affecting New York."


      The Trust is a unit  investment  trust formed for the purpose of obtaining
tax-exempt  interest  income  through  investment  in  a  diversified,   insured
portfolio  of long-term  bonds,  issued by or on behalf of the State of New York
and counties,  municipalities,  authorities or political subdivisions thereof or
issued by certain  United States  territories  or  possessions  and their public
authorities (the "Bonds"). See Part II under "The Trust." The Bonds deposited in
the portfolio of the Trust are sometimes referred to herein as the "Securities."
Insurance  guaranteeing  the payment of principal and interest on the Securities
while in the Trust has been  obtained by the Trust from the Insurer as set forth
in Part II under "Insurance on the Bonds." Such insurance does not guarantee the
market  value of the  Securities  or the Units  offered  hereby.  The payment of
interest and the  preservation  of principal are, of course,  dependent upon the
continuing  ability of the  issuers  of the Bonds and any other  insurer to meet
their  obligations.  As a result of the  insurance  on the Bonds,  the Units are
rated "AAA" by Standard & Poor's Ratings Services, a Division of The McGraw-Hill
Companies ("Standard & Poor's").


      In the  opinion  of special  counsel  for the  Sponsors  as of the Date of
Deposit, interest on the Bonds that is excludable from federal gross income when
received by the Trust will be  excludable  from the federal  gross income of the
Unit holders and with certain exceptions, interest income to the Unit holders is
generally  exempt  from all New York  State  and New York City  personal  income
taxes.  Capital  gains,  if any,  are  subject  to tax.  See Part II under  "Tax
Status."


      Offering.  The  initial  public  offering  of Units in the  Trust has been
completed.  The Units offered hereby are issued and outstanding Units which have
been  acquired  by the  Sponsors  either by  purchase  from the Trustee of Units
tendered for redemption or in the secondary market. See Part II under "Rights of
Unit Holders --  Redemption  -- Purchase by the  Sponsors of Units  Tendered for
Redemption"  and  "Public  Offering -- Market for Units." The price at which the
Units  offered  hereby  were  acquired  was not less than the  redemption  price
determined  as described  herein.  See Part II under  "Rights of Unit Holders --
Redemption -- Computation of Redemption Price per Unit."

      The Public Offering Price of the Units is based on the aggregate bid price
of the Securities in the Trust divided by the number of Units outstanding,  plus
a sales charge  determined on the basis of the  maturities of the  Securities in
the  Trust.  See  "Public  Offering  --  Offering  Price"  in  Part  II of  this
Prospectus.

      Market for Units. The Sponsors,  although they are not obligated to do so,
intend to  maintain a  secondary  market for the Units at prices  based upon the
aggregate bid price of the Securities in the Trust plus accrued  interest to the
date of settlement, as more fully described in Part II under "Public Offering --
Market for Units." If such a market is not maintained, a Unit holder may be able
to  dispose  of his Units  only  through  redemption  at prices  based  upon the
aggregate  bid price of the  underlying  Securities.  The purchase  price of the
Securities  in the  Trust,  if  they  were  available  for  direct  purchase  by
investors,  would not include the sales charges  included in the Public Offering
Price of the Units.

      Investors   should  retain  both  Parts  of  this  Prospectus  for  future
reference.

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION OR ANY STATE  SECURITIES  COMMISSION NOR HAS THE SECURITIES
AND  EXCHANGE  COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

- -------------------

1.  The number of units is expressed in whole  numbers  with no  adjustment  for
    fractional units.

2.  The sales charge is determined  based on the  maturities  of the  underlying
    securities in the portfolio. See "Public Offering -- Offering Price" in Part
    II of this Prospectus.


3.  Plus accrued interest to September 3, 1999, the expected date of settlement,
    of $2.57 monthly and $15.58 semi-annually.


4.  Based solely upon the bid side evaluations of the portfolio securities. Upon
    tender for redemption, the price to be paid will include accrued interest as
    described  in  Part II  under  "Rights  of Unit  Holders  --  Redemption  --
    Computation of Redemption Price per Unit."

5.  Estimated  Current Return is calculated by dividing the estimated net annual
    interest  income  received  in cash per Unit by the Public  Offering  Price.
    Interest  income per Unit will vary with changes in fees and expenses of the
    Trustee and the Evaluator,  and with the redemption,  maturity,  exchange or
    sale of  Securities.  This  calculation,  which includes cash income accrual
    only, does not include  discount  accretion on original issue discount bonds
    or on zero coupon  bonds or premium  amortization  on bonds  purchased  at a
    premium.  See "Tax  Status"  and  "Estimated  Current  Return and  Estimated
    Long-Term Return to Unit Holders" in Part II of this Prospectus.

6.  Estimated  Long-Term Return is calculated by using a formula that takes into
    account the yields  (including  accretion of discounts and  amortization  of
    premiums)  of the  individual  Bonds in the Trust's  portfolio,  weighted to
    reflect the market  value and time to maturity  (or,  in certain  cases,  to
    earlier  call date) of such Bonds,  adjusted to reflect the Public  Offering
    Price (including sales charge and expenses) per Unit. See "Estimated Current
    Return and  Estimated  Long-Term  Return to Unit Holders" in Part II of this
    Prospectus.

       Portfolio Information
       ---------------------

       On July 31,  1999,  the bid  side  valuation  of  27.1% of the  aggregate
principal amount of Bonds in the Portfolio for this Trust was at a discount from
par and 72.9%  was at a  premium  over  par.  See Note (B) to  "Tax-Exempt  Bond
Portfolio" for information concerning call and redemption features of the Bonds.

       Special Factors Concerning the Portfolio
       ----------------------------------------

       On July 31, 1999,  the Portfolio  consisted of six issues of Bonds issued
by  entities  located  in New  York or  certain  United  States  territories  or
possessions.  The following information is being supplied to inform Unit Holders
of circumstances  affecting the Trust. 4.7% of the aggregate principal amount of
the Bonds in the Portfolio are general obligations of the governmental  entities
issuing them and are backed by the taxing power thereof.  95.3% of the aggregate
principal  amount of the Bonds in the  Portfolio  are payable from the income of
specific  projects or authorities and are not supported by the issuers' power to
levy taxes.

       Although  income  to pay such  Bonds  may be  derived  from more than one
source,  the  primary  sources of such  income,  the  number of issues  (and the
related dollar  weighted  percentage of such issues)  deriving  income from such
sources and the purpose of issue are as follows: General Obligation, one (4.7%);
Revenue:   Health   Care,   two   (49.5%);   Higher   Education,   one  (22.4%);
Transportation,  one (12.4%) and Housing, one (11.0%). The Trust is deemed to be
concentrated in the Health Care Bonds category.1 Five issues, constituting 89.0%
of the Bonds in the Portfolio are original issue discount bonds, one of which is
a zero coupon bond. All issues were rated AAA by Standard & Poor's.2  Subsequent
to such date, such ratings may have changed.  See "Tax-Exempt  Bond  Portfolio."
For a more detailed discussion,  it is recommended that Unit Holders consult the
official statements for each Security in the Portfolio of the Trust.

       Interest  income on the Bonds contained in the Trust Portfolio is, in the
opinion of bond counsel to the issuing governmental authorities, excludable from
gross income under the Internal Revenue Code of 1986, as amended. See "The Trust
- -- Portfolio" in Part II of this Prospectus.


       Tax Status
       ----------

       Interest on the Bonds in the Trust  Portfolio  is  generally  exempt from
federal income taxes. It is also generally  exempt from New York State and local
personal  income  taxes.  Bond counsel to the issuing  governmental  authorities
delivered their opinions confirming the tax-exempt status of the interest on the
dates of issuance of the Bonds.  See "The Trust - Portfolio"  in Part II of this
Prospectus.

       In the opinion of counsel to the  sponsor,  the Trust is not treated as a
separate taxable entity,  and instead the Unit Holders will be treated as owning
the Trust's assets and as receiving the Trust's income.

       Gain or loss  realized on a sale,  maturity or redemption of the Bonds by
the Trust or on a sale or  redemption  of a Unit by a Unit  Holder must be taken
into  account  for  federal,  state and local  income tax  purposes.  It will be
capital  gain or loss if the Units are held as  capital  assets and will be long
term if the Units  (and the  Bonds)  have been held for more than one year.  The
gain or loss on  disposition  does  not  include  any  amount  received  that is
attributable  to accrued  interest or earned  original issue discount  (which is
generally treated as tax-exempt  interest) or any accrued market discount (which
is generally treated as ordinary income). Long-term capital gains realized by


                                       4
<PAGE>



noncorporate  taxpayers  are taxed at a maximum  federal  income tax rate of 20%
while  ordinary  income and short-term  capital gains  received by  noncorporate
taxpayers will be taxed at regular federal income tax rates of up to 39.6%.

- -------------------

  1     A Trust is considered to be "concentrated"  in a particular  category or
issuer when the Bonds in that category or of that issuer  constitute 25% or more
of the  aggregate  face  amount  of the  Portfolio.  See "The  Trust --  General
Considerations" in Part II of this Prospectus.

  2     For the meanings of ratings,  see  "Description of Bond Ratings" in Part
II of this Prospectus.

We have  audited  the  accompanying  statement  of net  assets of  Empire  State
Municipal  Exempt Trust,  Guaranteed  Series 122,  including the tax-exempt bond
portfolio,  as of July 31, 1999,  and the related  statements of operations  and

financial  statements are the responsibility of the Trustee.  Our responsibility
is to express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1999, by correspondence with the
Trustee.  An audit also includes  assessing the accounting  principles  used and
significant  estimates  made by the Trustee,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position of Empire State Municipal Exempt
Trust,  Guaranteed  Series  122 as of July  31,  1999,  and the  results  of its

                       ===================================



The Trust is a unit investment trust formed under the Investment  Company Act of
1940 for the purpose of obtaining  tax-exempt interest income through investment
in a fixed  insured  portfolio of  long-term  bonds,  issued  primarily by or on
behalf of the State of New York and  counties,  municipalities,  authorities  or
political subdivisions thereof.

The Bank of New York (the "Trustee") has custody of and  responsibility  for the
accounting records and financial  statements of the Trust and is responsible for
establishing and maintaining a system of internal control.

The Trustee is also  responsible  for all  estimates  of expenses  and  accruals
reflected  in the  Trust's  financial  statements.  The  accompanying  financial
statements   have  been   adjusted   to  record  the   unrealized   appreciation
(depreciation)  of investments and to record interest income and expenses on the
accrual basis.


NOTE 1 - ACCOUNTING POLICIES

           Securities

                Securities  are stated at bid side market value as determined by
an independent  outside evaluator.  Securities  transactions are recorded on the
trade  date.  The  difference  between  cost and market  value is  reflected  as
unrealized appreciation  (depreciation) of investments.  Realized gains (losses)
from securities  transactions are determined on the basis of average cost of the
securities sold or redeemed.

           Taxes on income

                The Trust is not subject to taxes on income and, accordingly, no
provision has been made.

           Termination of Trust

                The  mandatory  termination  date of the Trust is  December  31,
2044.  If the value of the Trust falls below  $2,000,000  or 20% of the value of
the Trust as of the date of deposit, whichever is lower, the Trust is subject to
termination as specified in the Trust Agreement.

           Organizational costs

                Organizational  costs are being  amortized over a period of five
years using the straight-line method.

           Value per unit

                Included  in value  per  unit is  undistributed  net  investment
income per unit.  This  represents  income  earned and accrued to each unit less
amounts  distributed to the Unit Holder. The last income distribution dates were
July 1 and  June 1,  1999 for  Unit  Holders  electing  monthly  or  semi-annual
distributions,  respectively,  resulting  in a higher  value  per unit for those
electing semi-annual distributions than those electing monthly distributions.

semi-annually  on the first day of June and  December or, if elected by the Unit
Holder, on the first day of each month, after deducting applicable expenses.

                       NOTES TO TAX-EXEMPT BOND PORTFOLIO


(A)     A description  of the rating  symbols and their  meanings  appears under
        "Description of Bond Ratings" in Part II of this Prospectus. Ratings are
        by Standard & Poor's.  Certain bond ratings have changed  since the Date
        of  Deposit,  at which  time all such  bonds  were  rated A or better by
        Standard & Poor's.

(B)     Bonds may be redeemable prior to maturity from a sinking fund (mandatory
        partial redemption) (S.F.) or at the stated optional call (at the option
        of the issuer)  (Opt.) or by  refunding.  Certain bonds in the portfolio
        may be  redeemed  earlier  than  dates  shown in whole or in part  under
        certain unusual or extraordinary circumstances as specified in the terms
        and provisions of such bonds.

             Prospectus, Part I 9,263 Units Dated: November 29, 1999

             NOTE: Part I of this Prospectus may not be distributed
                         unless accompanied by Part II.

      This Prospectus  consists of two parts. The first part contains a "Summary
of Essential Financial  Information" on the reverse hereof as of August 31, 1999
and a summary of additional  specific  information  including  "Special  Factors
Concerning  the  Portfolio"  and  audited  financial  statements  of the  Trust,
including the related bond  portfolio,  as of July 31, 1999.  The second part of
this  Prospectus  contains a general  summary of the Trust and "Special  Factors
Affecting New York."


      The Trust is a unit  investment  trust formed for the purpose of obtaining
tax-exempt  interest  income  through  investment  in  a  diversified,   insured
portfolio  of long-term  bonds,  issued by or on behalf of the State of New York
and counties,  municipalities,  authorities or political subdivisions thereof or
issued by certain  United States  territories  or  possessions  and their public
authorities (the "Bonds"). See Part II under "The Trust." The Bonds deposited in
the portfolio of the Trust are sometimes referred to herein as the "Securities."
Insurance  guaranteeing  the payment of principal and interest on the Securities
while in the Trust has been  obtained by the Trust from the Insurer as set forth
in Part II under "Insurance on the Bonds." Such insurance does not guarantee the
market  value of the  Securities  or the Units  offered  hereby.  The payment of
interest and the  preservation  of principal are, of course,  dependent upon the
continuing  ability of the  issuers  of the Bonds and any other  insurer to meet
their  obligations.  As a result of the  insurance  on the Bonds,  the Units are
rated "AAA" by Standard & Poor's Ratings Services, a Division of The McGraw-Hill
Companies ("Standard & Poor's").


      In the  opinion  of special  counsel  for the  Sponsors  as of the Date of
Deposit, interest on the Bonds that is excludable from federal gross income when
received by the Trust will be  excludable  from the federal  gross income of the
Unit holders and with certain exceptions, interest income to the Unit holders is
generally  exempt  from all New York  State  and New York City  personal  income
taxes.  Capital  gains,  if any,  are  subject  to tax.  See Part II under  "Tax
Status."


      Offering.  The  initial  public  offering  of Units in the  Trust has been
completed.  The Units offered hereby are issued and outstanding Units which have
been  acquired  by the  Sponsors  either by  purchase  from the Trustee of Units
tendered for redemption or in the secondary market. See Part II under "Rights of
Unit Holders --  Redemption  -- Purchase by the  Sponsors of Units  Tendered for
Redemption"  and  "Public  Offering -- Market for Units." The price at which the
Units  offered  hereby  were  acquired  was not less than the  redemption  price
determined  as described  herein.  See Part II under  "Rights of Unit Holders --
Redemption -- Computation of Redemption Price per Unit."

      The Public Offering Price of the Units is based on the aggregate bid price
of the Securities in the Trust divided by the number of Units outstanding,  plus
a sales charge  determined on the basis of the  maturities of the  Securities in
the  Trust.  See  "Public  Offering  --  Offering  Price"  in  Part  II of  this
Prospectus.

      Market for Units. The Sponsors,  although they are not obligated to do so,
intend to  maintain a  secondary  market for the Units at prices  based upon the
aggregate bid price of the Securities in the Trust plus accrued  interest to the
date of settlement, as more fully described in Part II under "Public Offering --
Market for Units." If such a market is not maintained, a Unit holder may be able
to  dispose  of his Units  only  through  redemption  at prices  based  upon the
aggregate  bid price of the  underlying  Securities.  The purchase  price of the
Securities  in the  Trust,  if  they  were  available  for  direct  purchase  by
investors,  would not include the sales charges  included in the Public Offering
Price of the Units.

      Investors   should  retain  both  Parts  of  this  Prospectus  for  future
reference.

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION OR ANY STATE  SECURITIES  COMMISSION NOR HAS THE SECURITIES
AND  EXCHANGE  COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

- -------------------

1.  The number of units is expressed in whole  numbers  with no adjustment for
    fractional units.

2.  The sales charge is determined  based on the maturities of the underlying
    securities in the portfolio.  See "Public  Offering -- Offering Price" in
    Part II of this Prospectus.


3.  Plus accrued interest to September 3, 1999, the expected date of settlement,
    of $2.50 monthly and $15.14 semi-annually.


4.  Based solely upon the bid side  evaluations of the portfolio  securities.
    Upon tender for  redemption,  the price to be paid will  include  accrued
    interest  as  described  in Part II  under  "Rights  of Unit  Holders  --
    Redemption -- Computation of Redemption Price per Unit."

5.  Estimated  Current  Return is  calculated  by dividing the  estimated net
    annual  interest  income received in cash per Unit by the Public Offering
    Price.  Interest  income  per Unit  will vary  with  changes  in fees and
    expenses  of the  Trustee  and the  Evaluator,  and with the  redemption,
    maturity,  exchange  or  sale  of  Securities.  This  calculation,  which
    includes cash income accrual only, does not include discount accretion on
    original  issue  discount  bonds  or on  zero  coupon  bonds  or  premium
    amortization  on bonds  purchased  at a  premium.  See "Tax  Status"  and
    "Estimated Current Return and Estimated Long-Term Return to Unit Holders"
    in Part II of this Prospectus.

6.  Estimated  Long-Term  Return is  calculated by using a formula that takes
    into  account  the  yields   (including   accretion   of  discounts   and
    amortization  of  premiums)  of  the  individual  Bonds  in  the  Trust's
    portfolio, weighted to reflect the market value and time to maturity (or,
    in certain  cases,  to  earlier  call date) of such  Bonds,  adjusted  to
    reflect the Public Offering Price  (including  sales charge and expenses)
    per Unit. See "Estimated Current Return and Estimated Long-Term Return to
    Unit Holders" in Part II of this Prospectus.

       Portfolio Information
       ---------------------

       On July 31,  1999,  the bid  side  valuation  of  26.7% of the  aggregate
principal amount of Bonds in the Portfolio for this Trust was at a discount from
par and 73.3%  was at a  premium  over  par.  See Note (B) to  "Tax-Exempt  Bond
Portfolio" for information concerning call and redemption features of the Bonds.


           Special Factors Concerning the Portfolio
           ----------------------------------------

       On July 31, 1999, the Portfolio consisted of seven issues of Bonds issued
by  entities  located  in New  York or  certain  United  States  territories  or
possessions.  The following information is being supplied to inform Unit Holders
of circumstances  affecting the Trust. 5.3% of the aggregate principal amount of
the Bonds in the Portfolio are general obligations of the governmental  entities
issuing them and are backed by the taxing power thereof.  21.4% of the aggregate
principal amount of the Bonds in the Portfolio are payable from  appropriations.
73.3% of the  aggregate  principal  amount  of the  Bonds in the  Portfolio  are
payable  from  the  income  of  specific  projects  or  authorities  and are not
supported by the issuers' power to levy taxes.

       Although  income  to pay such  Bonds  may be  derived  from more than one
source,  the  primary  sources of such  income,  the  number of issues  (and the
related dollar  weighted  percentage of such issues)  deriving  income from such
sources and the purpose of issue are as follows: General Obligation, two (5.3%);
Appropriations,  one (21.4%); Revenue: Transportation,  three (48.5%) and Health
Care, one (24.8%).  The Trust is deemed to be concentrated in the Transportation
Bonds category.1 Six issues,  constituting  78.6% of the Bonds in the Portfolio,
are  original  issue  discount  bonds of which two are zero coupon  bonds.  Five
issues  (75.9%)  were  rated  AAA,  one issue  (2.7%) was rated A- and one issue
(21.4%)  was rated BBB+ by  Standard & Poor's.2  Subsequent  to such date,  such
ratings may have changed.  See "Tax-Exempt  Bond Portfolio." For a more detailed
discussion,  it is recommended that Unit Holders consult the official statements
for each Security in the Portfolio of the Trust.

       Interest  income on the Bonds contained in the Trust Portfolio is, in the
opinion of bond counsel to the issuing governmental authorities, excludable from
gross income under the Internal Revenue Code of 1986, as amended. See "The Trust
- -- Portfolio" in Part II of this Prospectus.


       Tax Status
       ----------

       Interest on the Bonds in the Trust  Portfolio  is  generally  exempt from
federal income taxes. It is also generally  exempt from New York State and local
personal  income  taxes.  Bond counsel to the issuing  governmental  authorities
delivered their opinions confirming the tax-exempt status of the interest on the
dates of issuance of the Bonds.  See "The Trust - Portfolio"  in Part II of this
Prospectus.

       In the opinion of counsel to the  sponsor,  the Trust is not treated as a
separate taxable entity,  and instead the Unit Holders will be treated as owning
the Trust's assets and as receiving the Trust's income.

       Gain or loss  realized on a sale,  maturity or redemption of the Bonds by
the Trust or on a sale or  redemption  of a Unit by a Unit  Holder must be taken
into  account  for  federal,  state and local  income tax  purposes.  It will be
capital  gain or loss if the Units are held as capital  assets and will be long-
term if the Units  (and the  Bonds)  have been held for more than one year.  The
gain or loss on  disposition  does  not  include  any  amount  received  that is
attributable  to accrued  interest or earned  original issue discount  (which is
generally treated as tax-exempt  interest) or any accrued market discount (which
is generally treated as ordinary income). Long-term capital gains realized by


                                       4
<PAGE>



noncorporate  taxpayers  are taxed at a maximum  federal  income tax rate of 20%
while  ordinary  income and short-term  capital gains  received by  noncorporate
taxpayers will be taxed at regular federal income tax rates of up to 39.6%.

- -------------------

  1     A Trust is considered to be "concentrated"  in a particular  category or
issuer when the Bonds in that category or of that issuer  constitute 25% or more
of the  aggregate  face  amount  of the  Portfolio.  See "The  Trust --  General
Considerations" in Part II of this Prospectus.

  2     For the meanings of ratings,  see  "Description of Bond Ratings" in Part
II of this Prospectus.

INDEPENDENT AUDITOR'S REPORT




The Sponsors,  Trustee and Unit Holders of Empire State Municipal
    Exempt Trust, Guaranteed Series 123:


We have  audited  the  accompanying  statement  of net  assets of  Empire  State
Municipal  Exempt Trust,  Guaranteed  Series 123,  including the tax-exempt bond
portfolio,  as of July 31, 1999,  and the related  statements of operations  and
changes in net assets for the years ended July 31,  1999,  1998 and 1997.  These
financial  statements are the responsibility of the Trustee.  Our responsibility
is to express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1999, by correspondence with the
Trustee.  An audit also includes  assessing the accounting  principles  used and
significant  estimates  made by the Trustee,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position of Empire State Municipal Exempt
Trust,  Guaranteed  Series  123 as of July  31,  1999,  and the  results  of its

                       ===================================



The Trust is a unit investment trust formed under the Investment  Company Act of
1940 for the purpose of obtaining  tax-exempt interest income through investment
in a fixed  insured  portfolio of  long-term  bonds,  issued  primarily by or on
behalf of the State of New York and  counties,  municipalities,  authorities  or
political subdivisions thereof.

The Bank of New York (the "Trustee") has custody of and  responsibility  for the
accounting records and financial  statements of the Trust and is responsible for
establishing and maintaining a system of internal control.

The Trustee is also  responsible  for all  estimates  of expenses  and  accruals
reflected  in the  Trust's  financial  statements.  The  accompanying  financial
statements   have  been   adjusted   to  record  the   unrealized   appreciation
(depreciation)  of investments and to record interest income and expenses on the
accrual basis.


NOTE 1 - ACCOUNTING POLICIES
- ----------------------------

           Securities
           ----------

                Securities  are stated at bid side market value as determined by
an independent  outside evaluator.  Securities  transactions are recorded on the
trade  date.  The  difference  between  cost and market  value is  reflected  as
unrealized appreciation  (depreciation) of investments.  Realized gains (losses)
from securities  transactions are determined on the basis of average cost of the
securities sold or redeemed.

           Taxes on income
           ---------------

                The Trust is not subject to taxes on income and, accordingly, no
provision has been made.

           Termination of Trust
           --------------------

                The  mandatory  termination  date of the Trust is  December  31,
2044.  If the value of the Trust falls below  $2,000,000  or 20% of the value of
the Trust as of the date of deposit, whichever is lower, the Trust is subject to
termination as specified in the Trust Agreement.

           Organizational costs
           --------------------

                Organizational  costs are being  amortized over a period of five
years using the straight-line method.

           Value per unit
           --------------

                Included  in value  per  unit is  undistributed  net  investment
income per unit.  This  represents  income  earned and accrued to each unit less
amounts  distributed to the Unit Holder. The last income distribution dates were
July 1 and  June 1,  1999 for  Unit  Holders  electing  monthly  or  semi-annual
distributions,  respectively,  resulting  in a higher  value  per unit for those
electing semi-annual distributions than those electing monthly distributions.

                       NOTES TO TAX-EXEMPT BOND PORTFOLIO



(A)     A description  of the rating  symbols and their  meanings  appears under
        "Description of Bond Ratings" in Part II of this Prospectus. Ratings are
        by Standard & Poor's.  Certain bond ratings have changed  since the Date
        of  Deposit,  at which  time all such  bonds  were  rated A or better by
        either Standard & Poor's or Moody's.

 (B)    Bonds may be redeemable prior to maturity from a sinking fund (mandatory
        partial redemption) (S.F.) or at the stated optional call (at the option
        of the issuer)  (Opt.) or by  refunding.  Certain bonds in the portfolio
        may be  redeemed  earlier  than  dates  shown in whole or in part  under
        certain unusual or extraordinary circumstances as specified in the terms
        and provisions of such bonds.

                       EMPIRE STATE MUNICIPAL EXEMPT TRUST
                                Guaranteed Series

                               PROSPECTUS, Part II

                   Note: Part II of this Prospectus may not be
                    distributed unless accompanied by Part I.


                                    THE TRUST

Organization

         The Trust is one of a Series of similar but  separate  unit  investment
trusts.  Each Trust was created under the laws of the State of New York pursuant
to a Trust  Indenture and Agreement (the "Trust  Agreement"),  dated the Date of
Deposit as set forth in "Summary of Essential  Financial  Information" in Part I
of this Prospectus,  among the Sponsors, the Trustee and the Evaluator. The Bank
of New York acts as  successor  Trustee of Series 1 through 22 and as Trustee of
Series 23 and  subsequent  Series.  Muller Data  Corporation  acts as  successor
Evaluator for Series 1 through 90 and as Evaluator for Series 91 and  subsequent
Series.  Glickenhaus & Co. and Lebenthal & Co., Inc. act as co-Sponsors  for all
Series (the "Sponsors").

         On the date of this  Prospectus,  each Unit  represented the fractional
undivided  interest  in the Trust set forth in Part I of this  Prospectus  under
"Summary  of  Essential  Financial  Information."  Thereafter,  if any Units are
redeemed  by the  Trustee,  the  fractional  undivided  interest  in  the  Trust
represented by each unredeemed Unit will increase,  although the actual interest
in the Trust  represented  by each such Unit will remain  essentially  the same.
Units will remain  outstanding  until redeemed upon tender to the Trustee by any
Unit holder,  which may include the Sponsors,  or until the  termination  of the
Trust Agreement for the related Trust. See "Rights of Unit Holders--Redemption."

         On the Date of Deposit for each Trust, the Sponsors  deposited with the
Trustee  obligations  or  contracts  for the purchase of such  obligations  (the
"Bonds" or "Securities"). Certain of the Bonds may have been purchased at prices
which resulted in original issue  discount,  market discount or the inclusion of
zero coupon bonds.  Bonds selling at market  discount tend to increase in market
value as they  approach  maturity  when the  principal  amount is payable,  thus
increasing the potential for gain. Any gain other than any earned original issue
discount  or accrued  interest  will be  taxable,  but that  income  will not be
realized until maturity, redemption or sale of the underlying Bonds or Units.

Objectives

         The  objective  of the Trust is to obtain  tax-exempt  interest  income
through an  investment in a fixed,  insured  portfolio  consisting  primarily of
various  long-term  municipal  bonds. No assurance can be given that the Trust's
objectives  will  be  achieved  because  these  objectives  are  subject  to the
continuing  ability of the  respective  issuers of the bonds in the Portfolio to
meet their  obligations  and of the  Insurer to meet its  obligations  under the
insurance.  In addition,  an investment in the Trust can be affected by interest
rate fluctuations.

         Series 6 through 30 and Series 31 and  subsequent  Series have obtained
insurance  guaranteeing  the payment of  principal  and interest on the Bonds in
each  respective  Trust from MBIA Inc.  and MBIA  Insurance  Corporation  ("MBIA
Corp."),  respectively  (MBIA Inc. and MBIA Corp. are  collectively  referred to
herein as the  "Insurer").  Insurance  obtained by the Trust  applies only while
Bonds are retained in the Trust.  Pursuant to  irrevocable  commitments  of MBIA
Inc.  and MBIA Corp.,  however,  in the event of a sale of a Bond from the Trust
the Trustee has the right to obtain  permanent  insurance for such Bond upon the
payment of a single  predetermined  insurance  premium  from the proceeds of the
sale of such Bond.  It is expected  that the Trustee will  exercise the right to
obtain  permanent  insurance for a Bond in such Series upon instruction from the
Sponsors  whenever  the  value of that Bond  insured  to its  maturity  less the
applicable permanent insurance premium and the related custodial fee exceeds the
value of the Bond without such insurance.  Insurance relates only to the payment
of  principal  and  interest  on the Bonds in the Trust but  neither  covers the
nonpayment  of any  redemption  premium on the Bonds nor  guarantees  the market
value of the  Units.  Certain  Bonds in the  Trust  may  also be  insured  under
insurance  obtained by the issuers of such Bonds or third parties  ("Pre-insured
Bonds").  As  a  result  of  the  insurance,  Moody's  Investors  Service,  Inc.
("Moody's")  has assigned a rating of "Aaa" to all of the Bonds in the Trust, as
insured,  and Standard & Poor's Ratings Services,  a division of The McGraw-Hill
Companies,  Inc.  ("Standard  & Poor's"),  has assigned a rating of "AAA" to the
Bonds while in the Trust. No  representation is made as to any insurer's ability
to meet its  commitments.  Insurance is not a substitute for the basic credit of
an issuer, but supplements the existing credit and provides  additional security
therefor.  A single or annual  premium is paid by the issuer or any other  party
for its insurance on  Pre-insured  Bonds,  and a monthly  premium is paid by the
Trust for the  insurance  it obtains  from the Insurer on the Bonds in the Trust
that are not  pre-insured by such Insurer.  No premium will be paid by the Trust
on Bonds pre-insured by MBIA Inc. and MBIA Corp. See "Insurance on the Bonds."

Portfolio

         In view of the Trust's objectives, the following factors, among others,
were considered in selecting the Bonds: (1) all the Bonds are obligations of the
State  of New  York  and  counties,  municipalities,  authorities  or  political
subdivisions   thereof  or  issued  by  certain  United  States  territories  or
possessions,  including  Puerto Rico,  and their public  authorities so that the
interest on them will be exempt from  Federal,  New York State and New York City
income tax under  existing law; (2) the Bonds are varied as to purpose of issue;
(3) in the  opinion of the  Sponsors,  the Bonds are fairly  valued  relative to
other  bonds  of  comparable  quality  and  maturity;  and (4)  availability  of
insurance for the payment of principal and interest on the Bonds.  Subsequent to
the Date of Deposit,  a Bond may cease to be rated or its rating may be reduced.
Neither event requires an elimination of such Bond from the portfolio,  but such
an event may be considered in the Sponsors'  determination to direct the Trustee
to dispose of the Bonds. See "Sponsors-- Responsibility."

         An   investment   in  Units  of  the  Trust  should  be  made  with  an
understanding  of  the  risks  entailed  in  investments  in  fixed-rate  bonds,
including the risk that the value of such bonds (and,  therefore,  of the Units)
will decline with increases in interest rates. Inflation and recession,  as well
as measures implemented to address these and other economic problems, contribute
to fluctuations in interest rates and the value of fixed-rate  bonds  generally.
The Sponsors cannot predict future economic policies or their

279831.18
                                       -2-

<PAGE>



consequences  nor,  therefore,  can they  predict  the  course or extent of such
fluctuations in the future.

Special Factors Affecting New York

         The information set forth below is derived from the official statements
and/or preliminary drafts of official statements prepared in connection with the
issuance of New York State and New York City municipal  bonds. The Sponsors have
not independently verified this information.

         Economic  Trends.  Over  the long  term,  the  State  of New York  (the
"State") and the City of New York (the "City") face serious  potential  economic
problems.  The City accounts for approximately 41% of the State's population and
personal  income,  and the City's financial health affects the State in numerous
ways.  The  State  historically  has been one of the  wealthiest  states  in the
nation. For decades, however, the State has grown more slowly than the nation as
a whole,  gradually eroding its 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 State and its localities have used these taxes to
develop and maintain their transportation networks, public schools and colleges,
public  health  systems,  other  social  services and  recreational  facilities.
Despite these benefits,  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.

         Notwithstanding  the  numerous  initiatives  that  the  State  and  its
localities may take to encourage  economic growth and achieve balanced  budgets,
reductions  in  Federal  spending  could  materially  and  adversely  affect the
financial condition and budget projections of the State and its localities.

         New York  City.  The  City,  with a  population  of  approximately  7.4
million,  is  an  international   center  of  business  and  culture.  Its  non-
manufacturing  economy is broadly based,  with the banking and securities,  life
insurance,   communications,   publishing,   fashion   design,   retailing   and
construction industries accounting for a significant portion of the City's total
employment  earnings.  Additionally,  the City is the nation's  leading  tourist
destination. The City's manufacturing activity is conducted primarily in apparel
and printing.

         For  each of the  1981  through  1998  fiscal  years,  the  City had an
operating  surplus,  before  discretionary   transfers,  and  achieved  balanced
operating  results as  reported in  accordance  with then  applicable  generally
accepted accounting principles ("GAAP"), after discretionary transfers. The City
has been  required to close  substantial  gaps  between  forecast  revenues  and
forecast expenditures in order to maintain balanced operating results. There can
be no  assurance  that the City will  continue  to maintain  balanced  operating
results as required by State law without tax or other revenue increases or

279831.18
                                       -3-

<PAGE>



reductions  in City  services or  entitlement  programs,  which could  adversely
affect the City's economic base.

         As required by 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  and outlines  proposed  gap-
closing  programs  for years with  projected  budget  gaps.  The City's  current
financial  plan  projects a surplus in the 1999 and 2000  fiscal  years,  before
discretionary  transfers,  and budget  gaps for each of the 2001,  2002 and 2003
fiscal  years.  This  pattern of current  year  surplus  operating  results  and
projected  subsequent  year budget gaps has been  consistent  through the entire
period since 1982, during which the City has achieved surplus operating results,
before discretionary transfers, for each fiscal year.

         The City depends on aid from the State of New York (the  "State")  both
to enable  the City to balance  its  budget  and to meet its cash  requirements.
There can be no assurance  that there will not be reductions in State aid to the
City from amounts currently projected; that State budgets will be adopted by the
April 1 statutory deadline, or interim appropriations  enacted; or that any such
reductions  or delays will not have  adverse  effects on the City's cash flow or
expenditures.  In addition,  the Federal budget negotiation process could result
in a reduction  in or a delay in the receipt of Federal  grants which could have
additional adverse effects on the City's cash flow or revenues.

         The Mayor is  responsible  for  preparing  the City's  financial  plan,
including  the City's  current  financial  plan for the 2000 through 2003 fiscal
years  (the  "2000-2003   Financial  Plan"  or  "Financial  Plan").  The  City's
projections set forth in the Financial Plan are based on various assumptions and
contingencies   which  are  uncertain  and  which  may  not  materialize.   Such
assumptions  and  contingencies  include the condition of the regional and local
economies,  the  provision  of State  and  Federal  aid and the  impact  on City
revenues and expenditures of any future Federal or State policies  affecting the
City.

         Implementation  of the  Financial  Plan is  dependent  upon the  City's
ability to market its securities successfully.  The City's financing program for
fiscal years 1999 through 2003  contemplates  the issuance of $10.091 billion of
general  obligation  bonds and  $5.340  billion of bonds to be issued by the New
York City Transitional  Finance  Authority (the "Finance  Authority") to finance
City capital projects.  In addition, it is currently expected that approximately
$2.8  billion  of  bonds  will  be  issued  by  the  Tobacco   Settlement  Asset
Securitization Corporation ("TSASC") and paid from revenues received pursuant to
a settlement of litigation  with the leading  cigarette  companies.  The Finance
Authority  and TSASC  were  created  as part of the  City's  effort to assist in
keeping the City's  indebtedness within the forecast level of the constitutional
restrictions  on the amount of debt the City is authorized to incur. If TSASC is
not able to issue  bonds in the  amount  expected,  the City  will  need to find
another  source  of  financing  or  substantially  curtail  or halt its  capital
program.  In addition,  the City issues  revenue and tax  anticipation  notes to
finance its  seasonal  working  capital  requirements.  The success of projected
public  sales of City bonds and notes,  New York City  Municipal  Water  Finance
Authority ("Water  Authority") bonds and Finance Authority bonds will be subject
to  prevailing  market  conditions.  The City's  planned  capital and  operating
expenditures  are dependent  upon the sale of its general  obligation  bonds and
notes,  and the Water  Authority,  Finance  Authority  and TSASC  bonds.  Future
developments concerning the City and public

279831.18
                                       -4-

<PAGE>



discussion of such developments,  as well as prevailing market  conditions,  may
affect the market for outstanding City general obligation bonds and notes.

         For the 1998 fiscal  year,  the City had an operating  surplus,  before
discretionary  and other transfers,  and achieved  balanced  operating  results,
after  discretionary  and other  transfers,  in accordance  with GAAP.  The 1998
fiscal  year is the  eighteenth  year that the City has  achieved  an  operating
surplus,  before  discretionary  and other  transfers,  and  balanced  operating
results, after discretionary and other transfers.

         The most recent quarterly modification to the City's financial plan for
the 1999 fiscal year,  submitted to the New York State  Financial  Control Board
(the  "Control  Board") on June 14, 1999 (the "1999  Modification"),  projects a
balanced budget in accordance with GAAP for the 1999 fiscal year.

         On June 14, 1999,  the City  released the  Financial  Plan for the 2000
through 2003 fiscal years,  which relates to the City and certain entities which
receive funds from the City. The Financial Plan reflects  changes as a result of
the City's expense and capital budgets for fiscal year 2000,  which were adopted
on June 7, 1999. The Financial Plan projects  revenues and  expenditures for the
2000 fiscal year  balanced in  accordance  with GAAP and  projects  gaps of $1.8
billion,  $1.9  billion and $1.8  billion for fiscal  years 2001  through  2003,
respectively.

         Changes since adoption of the City's Expense Budget for the 1999 fiscal
year in June 1998, prior to the financial plan submitted to the Control Board on
June 26,  1998  include:  (i) an  increase  in  projected  tax  revenues of $976
million,  $813 million,  $558  million,  $417 million and $1.4 billion in fiscal
years 1999 through 2003,  respectively;  (ii) $300 million,  $250 million,  $300
million and $300  million of  projected  resources  in fiscal years 2000 through
2003, respectively, from the receipt by the City of funds from the settlement of
litigation  with the  leading  cigarette  companies;  (iii) a  reduction  in the
assumed  collection  of $350 million of projected  rent  payments for the City's
airports to $210 million and a delay in the receipt of such payments from fiscal
year 2000 to fiscal year 2001; (iv) anticipated  proceeds from the proposed sale
of the Coliseum in fiscal year 2001 totaling $345 million; and (v) net increases
in spending of $638  million,  $691  million,  $679  million and $1.0 billion in
fiscal years 2000 through  2003,  including  spending  for  Medicaid,  education
initiatives,  anti-smoking  programs,  employee fringe benefit costs,  and other
agency  programs.  The 1999  Modification  and the  2000-  2003  Financial  Plan
includes a  proposed  discretionary  transfer  in the 1999  fiscal  year of $2.6
billion to pay debt  service due in fiscal year 2000,  for budget  stabilization
purposes,  a proposed  discretionary  transfer  in fiscal  year 2000 to pay debt
service  due  in  fiscal  year  2001  totaling  $429  million,  and  a  proposed
discretionary  transfer  in fiscal  year 2001 to pay debt  service due in fiscal
year 2002 totaling $345 million.

         In  addition,  the  Financial  Plan sets forth  gap-closing  actions to
eliminate  a  previously  projected  gap for the 2000  fiscal year and to reduce
projected gaps for fiscal years 2001 through 2003. The  gap-closing  actions for
the 2000  through 2003 fiscal  years  include:  (i)  additional  agency  actions
totaling  $605 million,  $486 million,  $409 million and $397 million for fiscal
years 2000  through  2003,  respectively;  (ii)  additional  Federal  aid of $75
million in each of fiscal years 2000 through  2003,  which  include the proposed
restoration  of $25  million  of  Federal  revenue  sharing  and $50  million of
increased  Federal  Medicaid aid; and (iii)  additional  State actions  totaling
approximately $125 million in each of fiscal years 2000 through 2003,

279831.18
                                       -5-

<PAGE>



including  Medicaid  cost  containment  initiatives  proposed in the  Governor's
Executive   Budget  for  State  fiscal  year   1999-2000,   which  would  reduce
expenditures  by the City by  approximately  $50 million in each of fiscal years
2000 through  2003,  and  proposals by the City that the State enact tort reform
legislation,  increase revenue sharing payments and expand State funding for low
income  uninsured  disabled  children.  The  Financial  Plan also reflects a tax
reduction  program,  which includes the elimination of the City's  non-residents
earning  tax, the proposed  extension  of current tax  reductions  for owners of
cooperative and condominium  apartments and a proposed income tax credit for low
income wage earners.

         The Financial Plan assumes:  (i) approval by the Governor and the State
Legislature of the extension of the 14% personal income tax surcharge,  which is
scheduled  to expire on December  31,  1999,  and which is  projected to provide
revenue of $572 million, $585 million, $600 million and $638 million in the 2000
through 2003 fiscal  years,  respectively;  (ii)  collection  of projected  rent
payments for the City's airports,  totaling $365 million,  $185 million and $155
million in the 2001  through  2003 fiscal  years,  respectively,  a  substantial
portion of which may depend on the successful  completion of  negotiations  with
The Port  Authority of New York and New Jersey or the  enforcement of the City's
rights under the existing leases through  pending legal action;  (iii) State and
Federal  approval of the State and Federal gap- closing actions  proposed by the
City in the Financial  Plan;  and (iv) receipt of the tobacco  settlement  funds
providing revenues or expenditure offsets in annual amounts ranging between $250
million  and $300  million.  The  Financial  Plan  provides no  additional  wage
increases for City employees after their  contracts  expire in fiscal years 2000
and 2001. In addition,  the economic and financial  condition of the City may be
affected by various  financial,  social,  economic and  political  factors which
could have a material effect on the City.

         On June 7, 1999,  the City  Council  adopted a budget  for fiscal  year
2000. The adopted budget includes lower  estimated debt service  expenditures in
fiscal year 2000  resulting from a $456 million  increase,  from $2.1 billion to
$2.6 billion, in the proposed  discretionary transfer in the 1999 fiscal year to
pay debt  service  due in fiscal  year 2000.  The $456  million  increase in the
discretionary   transfer   reflects   increased   tax  revenues  and   decreased
expenditures  in the 1999 fiscal year.  The adopted  budget also  includes  $220
million of spending  initiatives  proposed by the City Council,  other increased
spending and the net cost of revised tax reduction proposals,  which reflect the
repeal  of all of the City  non-resident  earnings  tax and the  elimination  of
certain of the previously proposed tax reduction initiatives.

         On July 16,  1998,  Standard & Poor's  revised its rating of City bonds
upward  from BBB+ to A-.  Moody's  rating of City bonds was  revised in February
1998 to A3 from Baa1.  On March 8, 1999,  Fitch revised its rating of City bonds
upward to A.  Moody's,  Standard  & Poor's and Fitch  currently  rate the City's
outstanding general obligation bonds A3, A- and A, respectively.

         New York  State  and its  Authorities.  The State  ended the  1998-1999
fiscal year in balance on a cash basis for the  1998-1999  fiscal  year,  with a
reported closing balance in the General Fund of $892 million,  after reserving a
projected $1.8 billion surplus for use in future years. The Governor's Executive
Budget  projects  balance on a cash basis for the 1999-2000  fiscal year, with a
closing  balance in the  General  Fund of $2.5  billion,  including  a projected
reserve of $1.79  billion  for use in fiscal  years  2000-2001  and 2001-  2002.
Subsequently, as a result of revisions to national and State economic forecasts,
the State  Division of the Budget has revised its  estimate of receipts  for the
1999-2000 fiscal year to include an additional $150 million

279831.18
                                       -6-

<PAGE>



in  receipts.  The  Legislature  and  the  State  Comptroller  will  review  the
Governor's  Executive  Budget  and are  expected  to  comment  on it.  The State
Assembly and the State Senate have each adopted budget resolutions which provide
an outline of intended  spending and revenue changes to the 1999-2000  Executive
Budget which, the Division of the Budget believes,  would, if enacted,  increase
the size of the State's  future budget gaps.  There can be no assurance that the
Legislature  will  enact the  Executive  Budget  into law,  or that the  State's
adopted  budget  projections  will not differ  materially and adversely from the
projections set forth in the Executive Budget.  Depending on the amount of State
aid  provided  to  localities,   and  whether  the  Medicaid  cost   containment
initiatives proposed in the Executive Budget are approved by the State, the City
might be required to make substantial  additional changes in its Financial Plan.
The State  budget for the State's  1999-2000  fiscal year was not adopted by the
statutory  deadline  of April  1,  1999.  However,  legislation  making  interim
appropriations  has been  enacted.  A  prolonged  delay in the  adoption  of the
State's budget beyond the statutory April 1 deadline without  continuing interim
appropriations could delay the projected receipt by the City of State aid.

         The State Financial Plan for the 1999-2000  fiscal year, which reflects
the 1999-2000 Executive Budget, contains projections of a potential imbalance in
the 2000-2001  fiscal year of $1.14 billion and in the 2001-2002  fiscal year of
$2.07  billion,  assuming  implementation  of  the  1999-2000  Executive  Budget
recommendations,   the  application  of  the  $1.79  billion  reserve  fund  and
implementation of $500 million of unspecified  efficiency  initiatives and other
actions in each of the 2000-2001 and 2001-2002 fiscal years,  respectively.  The
Executive Budget identifies  various risks,  including either a financial market
or broader economic  correction during the period,  which could adversely affect
these projections.



         Standard & Poor's rates the State's  general  obligation  bonds A+, and
Moody's  rates the  State's  general  obligation  bonds A2. On November 9, 1999,
Standard & Poor's  revised its rating on the State's  general  obligation  bonds
from A to A+.



         Litigation. A number of court actions have been brought involving State
finances.  The court actions in which the State is a defendant generally involve
State programs and miscellaneous tort, real property, and contract claims. While
the  ultimate  outcome  and  fiscal  impact,  if  any,  on the  State  of  those
proceedings and claims are not currently predictable,  adverse determinations in
certain of them might have a material adverse effect upon the State's ability to
carry out the 1999 Modification and 2000-2003 Financial Plan.

         The City has estimated that its potential  future  liability on account
of outstanding  claims against it as of June 30, 1998 amounted to  approximately
$3.5 billion.

General Considerations

         Because  certain  of the  Bonds  may from  time to time  under  certain
circumstances  be sold or redeemed or will mature in accordance with their terms
and the proceeds from such events will be  distributed  to Unit holders and will
not be reinvested,  no assurance can be given that the Trust will retain for any
length of time its present size and composition.  The inclusion of unrated Bonds
in certain Series of the Trust may result in less  flexibility in their disposal
and a loss to the Trust upon their disposition. Except as described in footnotes
to "Summary of Essential Financial Information" in

Part I of this  Prospectus,  interest  accrues to the  benefit  of Unit  holders
commencing  with the  expected  date of  settlement  for  purchase of the Units.
Neither the Sponsors nor the Trustee shall be liable in any way for any default,
failure or defect in any Security.

         The following  paragraphs  discuss the  characteristics of the Bonds in
the  Trust and of  certain  types of  issuers  of the  Bonds in the  Trust.  See
"Special Factors  Concerning the Portfolio" in Part I of this Prospectus.  These
paragraphs  discuss,   among  other  things,  certain  circumstances  which  may
adversely  affect the ability of such  issuers to make  payments of principal of
and interest on Bonds held in the  portfolio of the Trust or which may adversely
affect the  ratings of such  Bonds.  Because of the  insurance  obtained  by the
Sponsors or by the issuers,  however,  such changes should not adversely  affect
the Trust's  ultimate receipt of principal and interest or the Standard & Poor's
or Moody's ratings of the Bonds in the portfolio.  An investment in Units of the
Trust should be made with an  understanding of the risks that such an investment
may  entail,  certain of which are  described  below.  Unit  holders  may obtain
additional  information  concerning a particular  Bond by requesting an official
statement from the issuer of such Bond.

General Obligation Bonds

         General  obligation  bonds are  secured by the  issuer's  pledge of its
faith,  credit and taxing power for the payment of principal and  interest.  The
taxing power of any governmental  entity may be limited,  however, by provisions
of state  constitutions  or laws,  and an  entity's  credit  will depend on many
factors, including potential erosion of the tax base due to population declines,
natural  disasters,  declines in the state's  industrial  base or  inability  to
attract new  industries;  economic  limits on the ability to tax without eroding
the tax base;  state  legislative  proposals  or voter  initiatives  to limit ad
valorem  real  property  taxes;  and the  extent to which the  entity  relies on
Federal or state  aid,  access to capital  markets or other  factors  beyond the
state or entity's control.

Appropriations Bonds

         Many state or local  governmental  entities  enter into lease  purchase
obligations as a means for financing the acquisition of capital  projects (e.g.,
buildings or equipment,  among other things).  Such  obligations  are often made
subject to annual appropriations.  Certain Series of the Trust may contain Bonds
in the portfolio  that are, in whole or in part,  subject to and dependent  upon
(1) the governmental  entity making  appropriations from time to time or (2) the
continued  existence of special temporary taxes which require legislative action
for their reimposition.  The availability of any appropriation is subject to the
willingness  of the  governmental  entity  to  continue  to  make  such  special
appropriations  or to reimpose such special taxes.  The obligation to make lease
payments exists only to the extent of the monies  available to the  governmental
entity therefor,  and no liability is incurred by the governmental entity beyond
the  monies  so  appropriated.   Subject  to  the  foregoing,   once  an  annual
appropriation is made, the governmental entity's obligation to make lease rental
payments  is  absolute  and   unconditional   without  setoff  or  counterclaim,
regardless of contingencies, whether or not a given project is completed or used
by the governmental  entity and notwithstanding any circumstances or occurrences
which might arise. In the event of  non-appropriation,  certificate  holders' or
bondowners'  sole remedy  (absent  credit  enhancement)  generally is limited to
repossession  of the collateral  for resale or releasing,  and the obligation of
the  governmental  lessee is not backed by a pledge of the general credit of the
governmental

                                       -8-

<PAGE>



lessee.  In the event of non-appropriation, the Sponsors may instruct the
Trustee to sell such Bonds.

         Moral Obligation  Bonds.  Certain Series of the Trust may contain Bonds
in the portfolio that are secured by pledged  revenues and  additionally  by the
so-called "moral  obligation" of the State or a local  governmental body. Should
the  pledged  revenues  prove  insufficient,  the payment of such Bonds is not a
legal  obligation  of the  State  or local  government,  and is  subject  to its
willingness to appropriate funds therefor.

Revenue Bonds

         Mortgage Revenue Bonds.  Certain Bonds may be "mortgage revenue bonds".
Under the  Internal  Revenue  Code of 1986,  as amended  (the "Code") (and under
similar  provisions  of  the  prior  tax  law),  "mortgage  revenue  bonds"  are
obligations the proceeds of which are used to finance owner-occupied  residences
under programs which meet numerous statutory requirements relating to residency,
ownership,  purchase  price and target area  requirements,  ceiling  amounts for
state  and  local  issuers,  arbitrage  restrictions,  and  certain  information
reporting,  certification,  and  public  hearing  requirements.  There can be no
assurance that  additional  federal  legislation  will not be introduced or that
existing  legislation  will not be further  amended,  revised,  or enacted after
delivery of these Bonds or that certain required future actions will be taken by
the issuing governmental authorities, which action or failure to act could cause
interest on the Bonds to be subject to federal income tax. If any portion of the
Bond  proceeds  is not  committed  for the  purpose of the issue,  Bonds in such
amount could be subject to earlier mandatory redemption at par, including issues
of Zero Coupon Bonds (see "Original Issue Discount and Zero Coupon Bonds").

         Housing  Bonds.  Some of the  aggregate  principal  amount of Bonds may
consist of obligations of state and local housing authorities whose revenues are
primarily  derived from mortgage  loans to housing  projects for low to moderate
income  families.  Since  such  obligations  are not  general  obligations  of a
particular state or municipality and are generally  payable  primarily or solely
from rents and other fees,  adverse economic  developments  including failure or
inability to increase  rentals,  fluctuations  of interest  rates and increasing
construction  and operating costs may reduce revenues  available to pay existing
obligations.

         The  housing  bonds in the Trust,  despite  their  optional  redemption
provisions which generally do not take effect until ten years after the original
issuance dates of such Bonds (often referred to as "ten year call  protection"),
do contain provisions which require the issuer to redeem such obligations at par
from unused  proceeds of the issue within a stated period.  In recent periods of
declining interest rates there have been increased  redemptions of housing bonds
pursuant to such redemption  provisions.  In addition,  the housing bonds in the
Trust are also subject to mandatory  redemption  in part at par at any time that
voluntary or involuntary  prepayments  of principal on the underlying  mortgages
are made to the  trustee  for such Bonds or that the  mortgages  are sold by the
bond issuer. Prepayments of principal tend to be greater in periods of declining
interest  rates;  it is possible  that such  prepayments  could be sufficient to
cause a housing bond to be redeemed  substantially  prior to its stated maturity
date, earliest call date or sinking fund redemption date.

         Public Power Revenue Bonds.  General  problems of the electric  utility
industry include difficulty in financing large  construction  programs during an
inflationary  period;  restrictions on operations and increased costs and delays
attributable  to  environmental  considerations;  the  difficulty of the capital
markets in absorbing  utility debt and equity  securities;  the  availability of
fuel for  electric  generation  at  reasonable  prices,  including  among  other
considerations  the potential rise in fuel costs and the costs  associated  with
conversion to alternate  fuel sources such as coal;  technical  cost factors and
other problems associated with construction, licensing, regulation and operation
of  nuclear   facilities  for  electric   generation,   including   among  other
considerations the problems associated with the use of radioactive materials and
the  disposal of  radioactive  waste;  and the  effects of energy  conservation.
Certain Bonds may have been issued in  connection  with the financing of nuclear
generating  facilities.  In view of recent  developments in connection with such
facilities,  legislative and administrative actions have been taken and proposed
relating to the development and operation of nuclear generating facilities.  The
Sponsors  are unable to predict  whether  any such  actions or whether  any such
proposals or litigation,  if enacted or instituted,  will have an adverse impact
on the revenues  available to pay the debt service on the Bonds in the portfolio
issued to finance such nuclear projects.

         Each of the  problems  referred  to above  could  adversely  affect the
ability  of the  issuers  of public  power  revenue  bonds to make  payments  of
principal  of and/or  interest on such bonds.  Certain  municipal  utilities  or
agencies may have  entered into  contractual  arrangements  with  investor-owned
utilities  and large  industrial  users and  consequently  may be  dependent  in
varying  degrees on the  performance  of such contracts for payment of bond debt
service.

         Health Care Revenue Bonds.  Some of the aggregate  principal  amount of
Bonds may consist of hospital revenue bonds. Ratings of hospital bonds are often
initially  based on feasibility  studies which contain  projections of occupancy
levels, revenues and expenses. Actual experience may vary considerably from such
projections.  A  hospital's  gross  receipts  and net income will be affected by
future events and conditions including,  among other things, demand for hospital
services and the ability of the hospital to provide them, physicians' confidence
in hospital management  capability,  economic  developments in the service area,
competition,  actions by insurers and  governmental  agencies and the  increased
cost and possible unavailability of malpractice insurance. Additionally, a major
portion of hospital revenue  typically is derived from federal or state programs
such as Medicare and Medicaid  which have been revised  substantially  in recent
years and which are undergoing further review at the state and federal level.

         Proposals  for  significant  changes in the health  care system and the
present  programs  for  third  party  payment  of  health  care  costs are under
consideration in Congress and many states.  Future legislation or changes in the
areas noted above,  among other  things,  would affect all  hospitals to varying
degrees  and,  accordingly,  any  adverse  change in these  areas may affect the
ability of such issuers to make payment of principal and interest on such bonds.

         Higher Education Revenue Bonds.  Higher education revenue bonds include
debt of state and private colleges,  universities and systems,  and parental and
student loan obligations. The ability of universities and colleges to meet their
obligations is dependent upon various factors,

279831.18
                                      -10-

<PAGE>



including the revenues,  costs and  enrollment  levels of the  institutions.  In
addition, their ability may be affected by declines in Federal, state and alumni
financial  support,  fluctuations  in  interest  rates and  construction  costs,
increased maintenance and energy costs, failure or inability to raise tuition or
room charges and adverse results of endowment fund investments.

         Pollution  Control  Facility  Revenue  Bonds.  Bonds  in the  pollution
control  facilities  category include  securities  issued on behalf of a private
corporation,*  including  utilities,  to provide facilities for the treatment of
air, water and solid waste pollution. Repayment of these bonds is dependent upon
income  from the  specific  pollution  control  facility  and/or  the  financial
condition of the project corporation. See also "Private Activity Bonds."

         Other Utility Revenue Bonds.  Bonds in this category include securities
issued to finance natural gas supply,  distribution and transmission facilities,
public  water  supply,  treatment  and  distribution   facilities,   and  sewage
collection,  treatment  and  disposal  facilities.  Repayment  of these bonds is
dependent  primarily  on  revenues  derived  from the  billing  of  residential,
commercial and industrial  customers for utility  services,  as well as, in some
instances,  connection fees and hook-up charges.  Such utility revenue bonds may
be adversely  affected by the lack of  availability  of Federal and state grants
and by decisions of Federal and state regulatory bodies and courts.

         Solid Waste and Resource Recovery Revenue Bonds. Bonds in this category
include  securities  issued to finance  facilities  for removal and  disposal of
solid  municipal  waste.  Repayment of these bonds is dependent on factors which
may  include  revenues  from  appropriations  from a  governmental  entity,  the
financial condition of the private project corporation and revenues derived from
the  collection  of charges for disposal of solid  waste.  Repayment of resource
recovery  bonds may also be  dependent to various  degrees on revenues  from the
sale of  electric  energy or steam.  Bonds in this  category  may be  subject to
mandatory redemption in the event of project  non-completion,  if the project is
rendered uneconomical or if it is considered an environmental hazard.

         Transportation  Revenue  Bonds.  Bonds in this  category  include bonds
issued for airport facilities,  bridges,  turnpikes, port authorities,  railroad
systems or mass transit systems.  Generally,  airport facility revenue bonds are
payable  from  and  secured  by the  revenues  derived  from the  ownership  and
operation  of a particular  airport.  Payment on other  transportation  bonds is
often  dependent  primarily  or solely on  revenues  from  financed  facilities,
including user fees,  charges,  tolls and rents.  Such revenues may be adversely
affected by increased  construction  and maintenance  costs or taxes,  decreased
use,  competition from alternative  facilities,  scarcity of fuel,  reduction or
loss  of  rents  or  the   impact   of   environmental   considerations.   Other
transportation  bonds may be dependent primarily or solely on Federal,  state or
local assistance including motor fuel and motor vehicle taxes, fees and licenses
and, therefore, may be subject to fluctuations in such assistance.

         Special Tax Revenue  Bonds.  Bonds in this  category are bonds  secured
primarily or solely by receipt of certain state or local taxes,  including sales
and use taxes or excise taxes.  Consequently,  such bonds may


- --------

* For the purposes of the description of users of facilities,  all references to
"corporations"  shall be deemed to include any other  nongovernmental  person or
entity.

279831.18
                                      -11-

<PAGE>



be subject to fluctuations in the collection of such taxes.  Such bonds do not
include tax increment bonds or special assessment bonds.

         Other  Revenue  Bonds.  Certain  Series of the  Trust may also  contain
revenue bonds which are payable from and secured primarily or solely by revenues
from the ownership and operation of particular facilities,  such as correctional
facilities,  parking facilities,  convention centers,  arenas, museums and other
facilities  owned or used by a charitable  entity.  Payment on bonds  related to
such facilities is,  therefore,  primarily or solely  dependent on revenues from
such  projects,  including  user fees,  charges and rents.  Such revenues may be
affected  adversely by increased  construction  and maintenance  costs or taxes,
decreased use,  competition  from alternative  facilities,  reduction or loss of
rents or the impact of environmental considerations.

         Certain  Series of the Trust may also contain bonds that are secured by
direct  obligations  of the  U.S.  Government  or,  in some  cases,  obligations
guaranteed by the U.S. Government,  placed in an escrow account maintained by an
independent trustee until maturity or a predetermined  redemption date. In a few
isolated  instances to date, bonds which were thought to be escrowed to maturity
have been called for redemption prior to maturity.

Puerto Rico Bonds

         Certain  of the Bonds in the Trust may be  general  obligations  and/or
revenue  bonds of issuers  located in Puerto  Rico  which  will be  affected  by
general economic  conditions in Puerto Rico. The economy of Puerto Rico is fully
integrated  with  that  of the  mainland  United  States.  During  fiscal  1998,
approximately  90% of Puerto Rico's exports were to the United States  mainland,
which was also the  source  of 61% of Puerto  Rico's  imports.  In fiscal  1998,
Puerto Rico  experienced  a $8.5 billion  positive  adjusted  merchandise  trade
balance.  The dominant sectors of the Puerto Rico economy are  manufacturing and
services.  Gross product in fiscal 1993 was $25.1 billion ($24.5 billion in 1992
prices) and gross  product in fiscal 1997 was $32.1  billion  ($27.7  billion in
1992 prices).  This represents an increase in gross product of 27.7% from fiscal
1993 to 1997  (13.0%  in  1992  prices).  According  to the  Labor  Department's
Household Employment Survey, during fiscal 1998, total employment increased 0.8%
over fiscal  1997.  The  preliminary  figure of gross  product for fiscal  1998,
released in November 1998,  $34.7 billion  ($28.5 billion in 1992 prices).  This
represents  an increase of 8.1% (3.1% in 1992  prices)  over fiscal  1997.  This
preliminary growth rate is 0.1% above the original base line forecast for fiscal
1998.  The Planning  Board's  gross  product  forecast for fiscal 1999,  made in
February 1998,  projected an increase of 2.7% over fiscal 1998. According to the
Labor Department's  Household Employment Survey, during the first five months of
fiscal 1999,  total  employment  decreased  1.2% over the same period for fiscal
1998. Total monthly  employment  averaged 1,124,800 during the first five months
of fiscal 1999,  compared to 1,138,400  over the same period in fiscal 1998. The
seasonally adjusted unemployment rate for November 1998 was 13.3%.

Original Issue Discount Bonds and Zero Coupon Bonds

         Certain  Series of the Trust may contain  original issue discount bonds
and/or zero coupon  bonds.  Original  issue  discount  bonds are bonds that were
originally  issued at less than the market  interest rate. Zero coupon bonds are
original issue discount bonds that do not provide for the payment of any current
interest. For Federal income tax purposes, original issue discount on tax-exempt
bonds is treated as tax-exempt interest and must be

279831.18
                                      -12-

<PAGE>



accrued over the term of the bonds. On sale or redemption, the excess of (1) the
amount realized  (other than amounts  treated as tax-exempt  income as described
below),  over  (2) the  tax  basis  of such  bonds  (properly  adjusted,  in the
circumstances  described  below, for accrual of original issue discount) will be
treated as taxable income or loss. Holders of tax-exempt obligations issued with
original  issue  discount  (including  holders  of Units in a trust  such as the
Trust),  must  accrue  tax-exempt  original  issue  discount by using a constant
interest method. The basis of a tax-exempt obligation is increased by the amount
of accrued tax-exempt  original issue discount.  These provisions are applicable
to obligations  issued after September 3, 1982 and acquired after March 1, 1984.
The  Trust's tax basis in a Bond is  increased  by any  accrued  original  issue
discount, as is a Unit holder's tax basis in its Units.

         It is possible that additional  Federal  legislation will be enacted or
that  existing  legislation  will be  amended  hereafter  with the  effect  that
interest  on the bonds  becomes  subject  to  Federal  income  taxation.  If the
interest on the Bonds should  ultimately  be deemed to be taxable,  the Sponsors
may instruct the Trustee to sell them,  and, since they would be sold as taxable
securities,  it is  expected  that they would  have to be sold at a  substantial
discount from current market prices.

Bonds Subject to Sinking Fund Provisions

         Most of the Bonds in the Trust are subject to redemption prior to their
stated maturity date pursuant to sinking fund or call provisions. A sinking fund
is a reserve  fund  accumulated  over a period of time for  retirement  of debt.
Sinking fund provisions are designed to redeem a significant portion of an issue
gradually  over the life of the issue.  Obligations to be redeemed are generally
chosen by lot. A callable debt  obligation is one which is subject to redemption
prior to maturity at the option of the issuer. To the extent that obligations in
the Trust have a bid side valuation  higher than their par value,  redemption of
such  obligations  at par would  result in a loss of capital to a  purchaser  of
Units at the public  offering price.  The estimated  current return of the Units
might also be adversely  affected if the return on the retired  Bonds is greater
than the average return on the Bonds in the Trust.  In general,  call provisions
are more likely to be exercised when the offering side valuation is at a premium
over par than when it is at a discount from par. See "Special Factors Concerning
the Portfolio" in Part I of this  Prospectus for  information  for the number of
bonds in the Portfolio  that are original  issue  discount and zero coupon bonds
and "Portfolio  Information" in Part I of this Prospectus for a breakdown of the
percentage  of Bonds in the Trust with  offering  side  valuations at a premium,
discount or at par. See also  "Estimated  Current Return and Estimated Long Term
Return".  "The Portfolio" in Part I of this Prospectus contains a listing of the
sinking  fund and call  provisions,  if any,  with  respect to each of the Bonds
therein.

Other Matters

         An amendment to the Federal  Bankruptcy  Act relating to the adjustment
of  indebtedness  owed  by  any  political   subdivision  or  public  agency  or
instrumentality  of any state,  including  municipalities,  became  effective in
1979.  Among other things,  this  amendment  facilitates  the use of proceedings
under the Federal  Bankruptcy Act by any such entity to restructure or otherwise
alter the terms of its  obligations,  including those of the type comprising the
Trust's portfolio.  The Sponsors are unable to predict what effect, if any, this
legislation will have on the Trust.


279831.18
                                      -13-

<PAGE>



         To the best knowledge of the Sponsors,  there is no litigation  pending
as of the date hereof in respect of any  Securities  which might  reasonably  be
expected to have a material adverse effect on the Trust, unless otherwise stated
in Part I of this Prospectus. At any time, however,  litigation may be initiated
on a variety of grounds with respect to Securities in the Trust. Such litigation
as, for example,  suits  challenging  the issuance of pollution  control revenue
bonds under recently enacted environmental  protection statutes,  may affect the
validity of such  Securities  or the tax-free  nature of the  interest  thereon.
While the  outcome  of such  litigation  can never be  entirely  predicted  with
certainty,  bond counsel have given opinions to the issuing  authorities of each
Bond on the date of  issuance  to the  effect  that  such  Securities  have been
validly  issued and that the  interest  thereon is exempt from  regular  Federal
income tax. In addition,  other  litigation or other factors may arise from time
to time which  potentially may impair the ability of issuers to meet obligations
undertaken with respect to Securities.


                                 PUBLIC OFFERING

Offering Price

         The Public  Offering  Price of the Units is based on the  aggregate bid
price of the Bonds in the Trust (as  determined by the  Evaluator)  plus a sales
charge  determined  in  accordance  with the schedule set forth below,  which is
based  upon  the  maturities  of  each  Bond in the  Trust.  The  Sponsors  have
implemented  this variable  format as a more  equitable  method of assessing the
sales charge for secondary  market  purchases.  For the purpose of computing the
sales  charge,  Bonds are deemed to mature on their  expressed  maturity  dates,
unless the Evaluator  evaluates the price of the Bonds to a different date, such
as a call date or a mandatory  tender date,  in which case the maturity  will be
deemed to be such other date.  This method of  computing  the sales  charge will
apply  different  sales charge rates to each Bond in the Trust  depending on the
maturity of each Bond in accordance with the following schedule:

         A minimum sales charge of 1.0% of the Public  Offering Price is applied
to all  secondary  market unit  purchases.  There is no  reduction  of the sales
charge for volume purchases in secondary market transactions.

         A  proportionate  share of accrued  and  undistributed  interest on the
Securities  at the date of delivery of the Units to the  purchaser is also added
to the Public Offering Price.

         Unless Securities are in default in payment of principal or interest or
in significant risk of such default,  the Evaluator will not attribute any value
to the Units due to the  insurance  obtained by the Trust.  See also  "Rights of
Unit  Holders--Certificates"  and  "Rights  of Unit  Holders--  Redemption"  for
information  relating to redemption of Units. The Evaluator will consider in its
evaluation  of Defaulted  Bonds which are covered by  insurance  obtained by the
Trust the value of the insurance guaranteeing interest and principal payments as
well as the  market  value of the  Securities  and the  market  value of similar
securities  of  issuers  whose  securities,  if  identifiable,  carry  identical
interest  rates and  maturities  and are of  creditworthiness  comparable to the
issuer prior to the default or risk of default. If such other securities are not
identifiable, the Evaluator will compare prices of securities with substantially
identical  interest rates and maturities  and of a  creditworthiness  of minimum
investment  grade.  As to  Series  18 and  subsequent  Series,  the value of the
insurance  will be equal  to the  difference  between  (i) the  market  value of
Defaulted Bonds assuming the exercise of the right to obtain Permanent Insurance
(less the insurance premium  attributable to the purchase of Permanent Insurance
and the related custodial fee) and (ii) the market value of such Defaulted Bonds
not covered by Permanent Insurance.  In any case the Evaluator will consider the
ability  of the  Insurer to meet its  commitments  under the  Trust's  insurance
policy and, in the case of Series 18 and subsequent Series,  MBIA Inc.'s or MBIA
Corp.'s  commitment  to issue  Permanent  Insurance.  For a  description  of the
circumstances  under  which a full or  partial  suspension  of the right of Unit
holders  to  redeem  their  Units  may  occur,  see  "Rights  of Unit  Holders--
Redemption."

         It is the present  intention of the Trustee (and, in the case of Series
18 and  subsequent  Series,  assuming the Trustee does not exercise the right to
obtain  Permanent  Insurance  on any  Defaulted  Bonds),  so long  as the  Trust
contains either some Bonds not in default or any Pre-insured  Bonds, not to sell
Defaulted  Bonds to effect  redemptions  or for any other  reason  but rather to
retain  them  in the  portfolio  BECAUSE  VALUE  ATTRIBUTABLE  TO THE  INSURANCE
OBTAINED BY THE TRUST CANNOT BE REALIZED  UPON SALE.  Insurance  obtained by the
issuer of a Pre-insured  Bond,  or by some other party,  is effective so long as
such  Pre-insured  Bond is outstanding and the insurer of such Bond continues to
fulfill its  obligations.  Therefore,  any such  insurance  may be considered to
represent an element of market value in regard to the Pre-insured  Bond, but the
exact  effect,  if any,  of  this  insurance  on such  market  value  cannot  be
predicted. Regardless of whether the insurer of a Pre- insured Bond continues to
fulfill  its  obligations,  however,  such Bond will in any case  continue to be
insured  under the policy  obtained by the Trust from the Insurer as long as the
Bond is held in the Trust.

         Certain  commercial  banks are making  Units of the Trust  available to
their  customers on an agency  basis.  A portion of the sales  charge  discussed
above is retained by or remitted to the banks.  Under the Glass-  Steagall  Act,
banks are prohibited from underwriting Trust Units;  however, the Glass-Steagall
Act does permit certain agency  transactions,  and banking  regulators  have not
indicated that these particular agency transactions are not permitted under such
Act.

Market for Units

         Although they are not obligated to do so, the Sponsors have  maintained
and intend to continue  to  maintain a market for the Units and to  continuously
offer to  purchase  Units at  prices  based on the  aggregate  bid  price of the
Securities. The Sponsors' Repurchase Price shall be not less

279831.18
                                      -15-

<PAGE>



than the  Redemption  Price plus accrued  interest  through the expected date of
settlement. See "Rights of Unit  Holders--Redemption--Computation  of Redemption
Price per Unit."  There is no sales  charge  incurred  when a Unit holder  sells
Units  back to the  Sponsors.  Any  Units  repurchased  by the  Sponsors  may be
reoffered  to the public by the  Sponsors  at the Public  Offering  Price at the
time, plus accrued interest.

         If the supply of Units of any Series exceeds demand,  or for some other
business reason, the Sponsors may discontinue  purchases of Units of such Series
at prices based on the  aggregate bid price of the  Securities.  The Sponsors do
not in any way  guarantee  the  enforceability,  marketability  or  price of any
Security  in the  portfolio  or of the Units of the  Trust.  In the event that a
market is not maintained for the Units, a Unit holder desiring to dispose of its
Units  may be able to do so only by  tendering  such  Units to the  Trustee  for
redemption at the Redemption Price,  which is based upon the aggregate bid price
of the underlying  Securities.  The aggregate bid price of the Securities in the
Trust may be expected to be less than the aggregate  offering  price.  If a Unit
holder wishes to dispose of its Units,  he should  inquire of the Sponsors as to
current  market  prices prior to making a tender for  redemption to the Trustee.
See "Rights of Unit Holders--Redemption" and "Sponsors."

         Employees (and their immediate  families) of the Sponsors may, pursuant
to employee benefit  arrangements,  purchase Units of the Trust at a price equal
to the bid side evaluation of the underlying securities in the Trust, divided by
the number of Units outstanding. Such arrangements result in less selling effort
and selling expenses than sales to employee groups of other  companies.  Resales
or transfers of Units purchased under the employee benefit arrangements may only
be  made  through  the  Sponsors'  secondary  market,  so  long  as it is  being
maintained.

Distribution of Units

         The  Sponsors  are  the  sole  underwriters  of  the  Units.  It is the
Sponsors'  intention to effect a public distribution of the Units solely through
their own organizations.  Units may, however, be sold to dealers who are members
of the National  Association  of Securities  Dealers,  Inc. at a discount.  Such
discount is subject to change  from time to time by the Agent for the  Sponsors.
Sales will be made only with  respect to whole Units,  and the Sponsors  reserve
the right to reject,  in whole or in part,  any order for the purchase of Units.
It is the Sponsors' intention to continue to qualify Units of the Trust for sale
where such  qualification  is necessary.  In  maintaining a market for the Units
(see "Public  Offering--Market for Units"), the Sponsors will realize profits or
sustain losses in the amount of any  difference  between the price at which they
buy Units and the price at which they  resell  such Units (the  Public  Offering
Price described in the currently  effective  Prospectus which includes the sales
charge  set  forth in Part I of this  Prospectus  under  "Summary  of  Essential
Financial  Information") or the price at which they may redeem such Units (based
upon the aggregate bid side evaluation of the  Securities),  as the case may be,
and to the extent that they earn sales charges on resales.


     ESTIMATED CURRENT RETURN AND ESTIMATED LONG-TERM RETURN TO UNIT HOLDERS

         Units of the Trust are offered on a "dollar price" basis.  In contrast,
tax-exempt  bonds  customarily are offered on a "yield price" basis.  Therefore,
the rate of return on each Unit is measured in terms of both

279831.18
                                      -16-

<PAGE>



Estimated  Current  Return and Estimated  Long-Term  Return.  Estimated  Current
Return  based on the  Public  Offering  Price per Unit and  Estimated  Long-Term
Return per Unit and  information  regarding  estimated  monthly and  semi-annual
distributions  of  interest  to Unit  holders  are set forth  under  "Summary of
Essential Financial Information" in Part I of this Prospectus.

         Estimated  Current  Return is computed by dividing  the  Estimated  Net
Annual  Interest  Income per Unit by the Public  Offering  Price.  Estimated Net
Interest  Income  per Unit will vary with  changes in fees and  expenses  of the
Trustee and the Evaluator and with principal prepayment,  redemption,  maturity,
exchange  or sale of Bonds.  The Public  Offering  Price per Unit will vary with
changes in the offering price of the Bonds.  Estimated Current Return takes into
account  only  the  interest  payable  on the  Bonds  and  does  not  involve  a
computation  of yield to maturity or to an earlier  redemption  date nor does it
reflect any  amortization  of premium or  discount  from par value in the Bond's
purchase price. Moreover, because interest rates on bonds purchased at a premium
are  generally  higher than  current  interest  rates on newly issued bonds of a
similar type with comparable ratings,  the Estimated Current Return per Unit may
be  affected  adversely  if such  Bonds are  redeemed  prior to their  maturity.
Therefore,  there is no assurance that the Estimated Current Return as set forth
under "Summary of Essential Financial  Information" in Part I of this Prospectus
will be realized in the future.

         Estimated Long-Term Return is calculated using a formula that (i) takes
into  consideration,  and determines and factors in the relative  weightings of,
the market values,  yields (taking into account the amortization of premiums and
the accretion of discounts)  and estimated  retirements  of all the Bonds in the
portfolio  and (ii) takes into account the expenses and sales charge  associated
with each Unit of the Trust.  The Estimated  Long-Term  Return assumes that each
Bond is retired on its pricing  life date (i.e.,  that date which  produces  the
lowest  dollar price when yield price  calculations  are done for each  optional
call date and the maturity date of a callable security).  If the Bond is retired
on any  optional  call or maturity  date other than the pricing  life date,  the
yield to the holder of that Bond will be greater than the initial  quoted yield.
Since the market values and estimated  retirements of the Bonds, the expenses of
the Trust and the Net Annual  Interest Income and Public Offering Price per Unit
may change,  there is no assurance  that the Estimated  Long-Term  Return as set
forth  under  "Summary of  Essential  Financial  Information"  in Part I of this
Prospectus will be realized in the future.


                             INSURANCE ON THE BONDS

         Insurance  guaranteeing the timely payment,  when due, of all principal
and interest on the Bonds in the Trust has been obtained from the Insurer by the
Trust.  The Insurer has issued a policy of insurance  covering each of the Bonds
in the Trust,  including  Pre-insured Bonds. As to each Trust, the Insurer shall
not have any  liability  under the policy with respect to any Bonds which do not
constitute  part of the Trust.  In determining to insure the Bonds,  the Insurer
has applied its own  respective  standards  which  generally  correspond  to the
standards it has established  for determining the  insurability of new issues of
municipal bonds.

         By the terms of its policy, the Insurer  unconditionally  guarantees to
the  Trust the  payment,  when due,  required  of the  issuer of the Bonds of an
amount  equal to the  principal  of  (either at the  stated  maturity  or by any
advancement  of maturity  pursuant  to a mandatory  sinking  fund  payment)  and
interest on the Bonds as such payments shall become due but not paid. Except

279831.18
                                      -17-

<PAGE>



as provided below with respect to small issue industrial  development  Bonds and
pollution  control  revenue Bonds,  in the event of any  acceleration of the due
date of  principal by reason of  mandatory  or optional  redemption  (other than
mandatory  sinking  fund  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 Trust from any trustee for the Bond
issuers or from any other  source.  The policy  issued by the  Insurer  does not
guarantee payment on an accelerated basis, the payment of any redemption premium
or the value of the Units.  The MBIA Inc.  and MBIA Corp.  policies  also do not
insure  against  nonpayment  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.  With  respect  to small  issue  industrial
development  Bonds and pollution control revenue Bonds,  however,  MBIA Inc. and
MBIA Corp.,  respectively,  guarantee the full and complete payments required to
be made by or on behalf of an issuer of such Bonds if there  occurs  pursuant to
the  terms of the Bonds an event  which  results  in the loss of the  tax-exempt
status of  interest  on such  Bonds,  including  principal,  interest or premium
payments  payable  thereon,  if any,  as and when  required  to be made by or on
behalf of the issuer  pursuant to the terms of such Bonds.  No assurance  can be
given  that the  policy  issued by the  Insurer  would  insure  the  payment  of
principal  or interest  on Bonds which is not  required to be paid by the issuer
thereof  because the Bonds were not validly issued.  At the respective  times of
issuance of the Bonds,  opinions  relating to the validity thereof were rendered
by bond counsel to the respective issuing authorities.

         The insurance policy relating to the Trust is  non-cancelable  and will
continue  in  force  so long as the  Trust is in  existence  and the  Securities
described in the policy  continue to be held in and owned by the Trust.  Failure
to pay  premiums  on the  policy  obtained  by the Trust  will not result in the
cancellation  of insurance but will force the Insurer to take action against the
Trustee to recover premium payments due it. The Trustee in turn will be entitled
to recover such payments from the Trust.

         The policy issued by the Insurer  shall  terminate as to any Bond which
has been redeemed from or sold by the Trustee on the date of such  redemption or
on the  settlement  date of such  sale,  and the  Insurer  shall  not  have  any
liability under the policy as to any such Bond  thereafter.  If the date of such
redemption or the settlement  date of such sale occurs between a record date and
a date of payment of any such  Bonds,  any MBIA Inc.  or MBIA Corp.  policy will
terminate  as to such  Bond on the  business  day next  succeeding  such date of
payment.  The  termination  of a MBIA Inc.  or MBIA Corp.  policy as to any Bond
shall not affect MBIA Inc.'s or MBIA  Corp.'s  obligations  regarding  any other
Bond in such Trust or any other  Trust  which has  obtained a MBIA Inc.  or MBIA
Corp.  insurance  policy.  The policy issued by the Insurer will terminate as to
all Bonds on the date on which the last of the Bonds matures,  is redeemed or is
sold by the Trust.

         Pursuant to an irrevocable  commitment of the Insurer, the Trustee upon
the sale of a Bond in the Trust has the right to obtain permanent insurance with
respect to such Bond (i.e.,  insurance to maturity of the Bonds) (the "Permanent
Insurance") upon the payment of a single  predetermined  insurance  premium from
the proceeds of the sale of such Bond.  Accordingly,  any Bond in such Series of
the Trust is eligible to be sold on an insured  basis.  It is expected  that the
Trustee will exercise the right to obtain Permanent  Insurance for a Bond in the
Trust upon  instruction  from the Sponsors  only if upon such exercise the Trust
would receive net proceeds  (sale of Bond  proceeds  less the insurance  premium
attributable to the Permanent Insurance

279831.18
                                      -18-

<PAGE>



and the related  custodial fee) from such sale in excess of the sale proceeds if
such Bond was sold on an uninsured basis.

         The Permanent Insurance premium with respect to each Bond is determined
based upon the  insurability of each Bond as of the Date of Deposit and will not
be increased or decreased  for any change in the  creditworthiness  of such Bond
unless such Bond is in default as to payment of principal  and/or  interest.  In
such event,  the  Permanent  Insurance  premium  shall be subject to an increase
predetermined  at the Date of Deposit and payable  from the proceeds of the sale
of such Bond.

         Except  as  indicated  below,  insurance  obtained  by the Trust has no
effect on the price or  redemption  value of Units  thereof.  It is the  present
intention of the Evaluator to attribute a value to the insurance obtained by the
Trust  (including  the right to obtain  Permanent  Insurance) for the purpose of
computing  the  price or  redemption  value of Units  thereof  only if the Bonds
covered by such insurance are in default in payment of principal or interest or,
in the  Sponsors'  opinion,  in  significant  risk of such  default  ("Defaulted
Bonds").  The value of the insurance will be equal to the difference between (1)
the market  value of a Bond which is in  default  in  payment  of  principal  or
interest or a significant  risk of default assuming the exercise of the right to
obtain  Permanent  Insurance  (less the insurance  premium  attributable  to the
purchase  of  Permanent  Insurance  and the related  custodial  fee) and (2) the
market  value of such  Bonds  not  covered  by  Permanent  Insurance.  Insurance
obtained by the issuer of a Bond or by parties other than the Trust is effective
so  long as  such  Pre-insured  Bond is  outstanding  and  the  insurer  of such
Pre-insured Bond continues to fulfill its obligations.

         Regardless  of whether the insurer of a Pre-insured  Bond  continues to
fulfill its  obligations,  however,  such Bond will continue to be insured under
the policy  obtained  by the Trust from MBIA Inc.  or MBIA Corp.  as long as the
Bond is held in the  Trust.  Insurance  obtained  by the  issuer of a Bond or by
other  parties may be  considered  to  represent  an element of market  value in
regard  to the  Bonds  thus  insured,  but the  exact  effect,  if any,  of this
insurance on such market value cannot be predicted.

         In the event that interest on or principal of a Bond is due for payment
but is unpaid by reason of  nonpayment by the issuer  thereof,  the Insurer will
make  payments to its fiscal agent,  as identified in the insurance  policy (the
"Fiscal  Agent"),  equal to such unpaid  amounts of  principal  and interest not
later than one business  day after the Insurer has been  notified by the Trustee
that such nonpayment has occurred (but not earlier than the date such payment is
due).  The Fiscal Agent will disburse to the Trustee the amount of principal and
interest  which is then due for payment but is unpaid upon receipt by the Fiscal
Agent of (1) evidence of the Trust's right to receive  payment of such principal
and  interest  and  (2)  evidence,  including  any  appropriate  instruments  of
assignment, that all of the rights to payment of such principal or interest then
due for payment shall thereupon vest in the Insurer. Upon payment by the Insurer
of any  principal or interest  payments  with respect to any Bonds,  the Insurer
shall  succeed to the  rights of the owner of such  Bonds  with  respect to such
payment.

         As of December 31, 1998, MBIA Corp. had admitted assets of $6.5 billion
(audited),  total liabilities of $4.2 billion  (audited),  and total capital and
surplus of $2.3  billion  (audited)  determined  in  accordance  with  statutory
accounting   practices   prescribed   or  permitted   by  insurance   regulatory
authorities. As of June 30, 1999, MBIA Corp. had admitted assets of $6.8 billion
(unaudited),  total liabilities of $4.5 billion  (unaudited),  and total capital
and surplus of $2.3 billion (unaudited)  determined in accordance with statutory
accounting   practices   prescribed   or  permitted   by  insurance   regulatory
authorities.  The address of MBIA Corp.  is 113 King  Street,  Armonk,  New York
10504.



         As of the Evaluation Date, the claims-paying  ability of MBIA Corp. has
been rated "AAA" by Standard & Poor's and "Aaa" by Moody's.

         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.  The Sponsors are not aware that the information
herein is inaccurate or incomplete as of the date hereof.

         The contract of insurance relating to the Trust and the negotiations in
respect thereof and certain agreements relating to Permanent Insurance represent
the only significant  relationship between the Insurer and the Trust. Otherwise,
neither  the  Insurer  nor  any  associate  thereof  has any  material  business
relationship,  direct or indirect,  with the Trust or the Sponsors,  except that
the  Sponsors  may from  time to time in the  normal  course  of their  business
participate  as  underwriters  or as  managers  or as  members  of  underwriting
syndicates  in the  distribution  of new issues of  municipal  bonds for which a
policy of insurance  guaranteeing the payment of interest and principal has been
obtained from the Insurer,  and except that James A. Lebenthal,  Chairman of the
Board of Directors of Lebenthal & Co., Inc., is a director of MBIA Inc. Although
all issues  contained in the  portfolio of the Trust are  individually  insured,
neither the Trust, the Units nor the portfolio is insured directly or indirectly
by the Insurer.

         A purpose of the  insurance on the Bonds in the  portfolio  obtained by
the  Trust is to  obtain a higher  yield on the Trust  portfolio  than  would be
available if all the  Securities  in such  portfolio had Standard & Poor's "AAA"
rating and/or  Moody's "Aaa" rating but were  uninsured and yet at the same time
to have the  protection of insurance of payment of interest and principal on the
Securities. There is, of course, no certainty that this result will be achieved.
Any  Pre-insured  Bonds in the Trust (all of which are rated "AAA" by Standard &
Poor's and/or "Aaa" by Moody's, respectively) may or may not have a higher yield
than  uninsured  bonds rated "AAA" by Standard & Poor's and/or "Aaa" by Moody's,
respectively.

         Because the  Securities are insured by the Insurer as to the payment of
principal  and  interest,  Moody's has  assigned a rating of "Aaa" to all of the
Bonds in the Trust,  as insured,  and  Standard & Poor's has  assigned its "AAA"
investment  rating to the Units and Bonds in the  Trust.  See "Tax  Exempt  Bond
Portfolio" in Part I of this  Prospectus.  These ratings apply to the Bonds only
while they are held in the Trust.  The  obtaining of these  ratings by the Trust
should not be  construed as an approval of the offering of the Units by Standard
& Poor's or Moody's or as a guarantee of the market value of the Trust or of the
Units.  These ratings are not a  recommendation  to buy, hold or sell and do not
take into account the extent to which Trust

279831.18
                                      -20-

<PAGE>


expenses or portfolio  asset sales for less than the Trust's  acquisition  price
will reduce payment to the Unit holders of the interest or principal.


         TAX STATUS (See also "Tax Status" in Part I of this Prospectus)

         Interest  income on the Bonds  contained in the Trust  portfolio is, in
the opinion of bond counsel to the issuing governmental  authorities rendered at
the time of original  issuance of the Bonds,  excludable from gross income under
the Internal Revenue Code of 1954, as amended (the "1954 Code"), or the Internal
Revenue  Code of 1986,  as  amended  (the  "Code"),  depending  upon the date of
issuance of the Bonds in any particular Series. See "The Trust-- Portfolio."


         Gain (or loss) realized on a sale,  maturity or redemption of the Bonds
or on a sale or redemption of a Unit is, however,  includable in gross income as
capital  gain (or  loss) for  Federal,  state and  local  income  tax  purposes,
assuming that the Unit is held as a capital asset.  Such gain (or loss) does not
include any amount  received in respect of accrued  interest,  accrued  original
issue discount or accrued  market  discount.  Gain on the  disposition of a Bond
purchased at a market  discount  generally  will be treated as ordinary  income,
rather  than  capital  gain,  to the  extent of  accrued  market  discount.  The
Administration's  Fiscal Year 2000 Budget  proposal would require accrual method
taxpayers  to accrue  market  discount on a current  basis.  Bonds  selling at a
market discount tend to increase in market value as they approach maturity, when
the principal amount is payable,  thus increasing the potential for taxable gain
(or  reducing the  potential  for loss) on their  redemption,  maturity or sale.
Capital gains realized by noncorporate  Unit holders on the disposition of Bonds
or Units will be taxed at a maximum  federal  income tax rate of 20% if the Unit
and the Bonds  have been held for more than one year,  whereas  ordinary  income
received by noncorporate  Unit holders will be taxed at a maximum federal income
tax rate of 39.6%. The  deductibility of capital losses is limited to the amount
of capital gain; in addition,  up to $3,000  ($1,500 for married  persons filing
separately)  of capital  losses of  non-corporate  Unit  holders may be deducted
against ordinary income.  Since the proceeds from sales of Bonds,  under certain
circumstances,  may not be distributed,  a Unit holder's  taxable income for any
year may exceed the actual cash distributions to the Unit holder in that year.

         Among other things,  the Code provides for the following:  (1) interest
on certain private  activity bonds issued after August 7, 1986 is an item of tax
preference  included in the calculation of the individual's  alternative minimum
tax currently taxed at a rate of up to 28% and the corporate alternative minimum
tax  currently  at a rate of  20%(however,  none of the  Bonds in the Trust is a
private  activity  bond,  the  interest on which is subject to this  alternative
minimum  tax);  (2)  75%  of the  amount  by  which  adjusted  current  earnings
(including  interest  on  all  tax-exempt  bonds,  such  as  the  Bonds)  exceed
alternative  minimum taxable income, as modified for this  calculation,  will be
included in alternative  minimum taxable income of  corporations  (the Code does
not otherwise  require  corporations,  and does not require taxpayers other than
corporations,  to treat  interest on the Bonds as an item of tax  preference  in
computing  alternative  minimum  tax);  (3)  subject to certain  exceptions,  no
financial   institution   is  allowed  a  deduction   for  the  portion  of  the
institution's  interest  expense  that is allocable  to  tax-exempt  interest on
tax-exempt  bonds acquired after August 7, 1986; (4) the amount of the deduction
allowed to property and casualty  insurance  companies for underwriting  loss is
decreased by an amount determined with regard to tax-exempt  interest income and
the deductible portion of dividends received by



279831.18
                                      -21-

<PAGE>



such  companies;  (5) all  taxpayers  are  required to report for  informational
purposes on their Federal  income tax returns the amount of tax-exempt  interest
they receive; (6) an issuer must meet certain requirements on a continuing basis
in order for interest on a  tax-exempt  bond to be  tax-exempt,  with failure to
meet such requirements resulting in the loss of tax exemption;  and (7) a branch
profits tax is imposed on U.S. branches of foreign  corporations which,  because
of the manner in which the branch profits tax is calculated, may have the effect
of subjecting the U.S. branch of a foreign  corporation to Federal income tax on
the interest on bonds otherwise exempt from such tax.


         Section  86 of the Code  provides  that a portion  of  social  security
benefits is includable in taxable income for taxpayers whose "modified  adjusted
gross  income,"  combined  with a portion  of their  social  security  benefits,
exceeds a base amount.  The base amount is $32,000 for a married couple filing a
joint return,  zero for married persons filing separate returns that do not live
apart from their  spouse at all times during the taxable  year,  and $25,000 for
all others.  Interest on tax-exempt  bonds is added to adjusted gross income for
purposes of determining  whether an individual's  income exceeds the base amount
described above.


         In addition,  certain "S corporations" may be subject to minimum tax on
certain passive income,  including tax-exempt interest,  such as interest on the
Bonds.

         At the time of the  original  issuance  of the Bonds held by the Trust,
opinions  relating to the  validity of the Bonds and the  exemption  of interest
thereon  from  Federal  income  tax were or (with  respect  to "when,  as and if
issued"  Bonds) were to be rendered by bond counsel to the issuing  governmental
authorities. Neither the Sponsors nor their special counsel have made any review
of  proceedings  relating  to the  issuance  of such Bonds or the basis for bond
counsel's opinions.

         In the case of certain  Bonds which may be  included in the Trust,  the
opinions  of bond  counsel  indicate  that,  although  interest on such Bonds is
generally exempt from Federal income tax, such Bonds are "industrial development
bonds"  under  the 1954  Code or are  "private  activity  bonds" as that term is
defined in the Code (the  following  discussion  also  applies to Bonds that are
"industrial  development  bonds" as they are  defined  in the 1954 Code in terms
similar to those under which private  activity bonds are defined in the Code and
are generally  subject to the same  limitations).  Interest on certain qualified
small issue  private  activity  bonds is exempt from Federal  income tax only so
long as the  "principal  user" of the  bond-financed  facility  and any "related
person" remain within the capital  expenditure  limitations of the Code and only
so long as the  aggregate  private  activity bond limits of the Code are met. In
addition,  interest on private  activity  bonds will not be exempt from  Federal
income tax for any  period  during  which such bonds are held by a  "substantial
user" of the  facilities  financed by the  proceeds of such bonds (or a "related
person" to such a "substantial user").  Interest  attributable to such Bonds, if
received by a Unit holder who is such a "substantial  user" or "related person,"
will be taxable (i.e.,  not tax-exempt) to the same extent as if such Bonds were
held directly as owner.

         In addition, a Bond can lose its tax-exempt status as a result of other
subsequent but unforeseeable events such as prohibited "arbitrage" activities by
the issuer of the Bond or the  failure of the Bond to  continue  to satisfy  the
conditions  required for the exemption of interest  thereon from regular federal
income tax. No investigation has been made as to the current or future owners or
users of the facilities financed by the bonds, the amount

                                      -22-

<PAGE>



of  such  persons'  outstanding  tax-exempt  private  activities  bonds,  or the
facilities themselves, and no assurance can be given that future events will not
affect the tax-exempt  status of the Bonds.  Investors  should consult their tax
advisors  for advice  with  respect to the effect of these  provisions  on their
particular tax situation.

         Under  Section 265 of the Code,  if  borrowed  funds are used by a Unit
holder to purchase or carry  Units of the Trust,  interest on such  indebtedness
will not be deductible for Federal income tax purposes.  Under rules used by the
Internal Revenue  Service,  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. Similar rules may be applicable for purposes
of state and local  taxation.  Investors  with  questions  regarding  this issue
should consult their tax advisors.

         The Trust may contain Bonds issued with original  issue  discount.  The
Code requires  holders of  tax-exempt  obligations  issued with  original  issue
discount,  such as the  Trust  (and  therefore  the  Unit  holders),  to  accrue
tax-exempt  original  issue  discount  by using  the  constant  interest  method
provided for the holders of taxable  obligations  and to increase the basis of a
tax-exempt  obligation  by the  amount  of  accrued  tax-exempt  original  issue
discount.  These provisions are applicable to obligations issued after September
3, 1982 and  acquired  after  March 1, 1984.  The Trust's tax basis in a Bond is
increased by any accrued  original  issue  discount,  as is a Unit  holder's tax
basis in its Units.

         If a Unit holder's tax cost for its pro rata interest in a Bond exceeds
its pro rata  interest  in the  Bond's  face  amount,  the Unit  holder  will be
considered  to have  purchased its pro rata interest in the Bond at a "premium."
The Unit holder will be  required  to amortize  any premium  relating to its pro
rata  interest  in a Bond prior to the  maturity  of the Bond.  Amortization  of
premium  on a Bond  will  reduce a Unit  holder's  tax  basis  for this pro rata
interest  in the  Bond,  but  will not  result  in any  deduction  from the Unit
holder's  income.  Thus,  for  example,  a Unit holder who  purchases a pro rata
interest in a Bond at a premium and resells it at the same price will  recognize
taxable gain equal to the portion of the premium that was  amortized  during the
period the Unit holder is considered to have held such interest.

         The exemption of interest on municipal  obligations  for Federal income
tax purposes does not necessarily  result in exemption under the income tax laws
of any state or local government.  Interest income derived from the Bonds is not
excluded  from  net  income  in  determining  New York  State  or New York  City
franchise taxes on corporations  or financial  institutions.  The laws of states
and local governments vary with respect to the taxation of such obligations.

         From time to time proposals have been introduced  before Congress,  the
purpose of which is to restrict or eliminate  the Federal  income tax  exemption
for interest on debt  obligations  similar to the Bonds in the Trust, and it can
be expected that similar proposals may be introduced in the future. The Sponsors
cannot predict whether additional legislation, if any, in respect of the Federal
income tax status of  interest on debt  obligations  may be enacted and what the
effect of such  legislation  would be on Bonds in the Trust.  In  addition,  the
enactment of a "flat tax" or other  legislation  that  significantly  alters the
federal  income tax system  may have a material  adverse  effect on the value of
Units. If the interest on any Bonds in the Trust should  ultimately be deemed to
be taxable, the Sponsors may instruct the Trustee to sell such Bonds, and, since
they would be sold as taxable

279831.18
                                      -23-

<PAGE>



securities,  it is expected  that they would be sold at a  substantial  discount
from current market prices.

         In South  Carolina  v.  Baker,  the U.S.  Supreme  Court  held that the
federal  government may  constitutionally  require states to register bonds they
issue and  subject  the  interest  on such  bonds to  federal  income tax if not
registered,  and that there is no constitutional prohibition against the federal
government's  taxing the interest earned on state or other municipal  bonds. The
Supreme  Court  decision  affirms the  authority  of the federal  government  to
regulate and control bonds such as the Bonds in the Trust and to tax interest on
such bonds in the future.  The decision  does not,  however,  affect the current
exclusion from gross income of the interest  earned on the Bonds in the Trust in
accordance with Section 103 of the Code.

         The opinions of counsel to the issuing governmental  authorities to the
effect that interest on the Bonds is exempt from regular  federal income tax may
be limited to law existing at the time the Bonds were issued,  and may not apply
to the extent that future changes in law, regulations or interpretations  affect
such Bonds.  Investors are advised to consult their own advisors for advice with
respect to the effect of any legislative changes.


                             RIGHTS OF UNIT HOLDERS

Certificates

         Ownership of Units is evidenced by registered  certificates executed by
the Trustee and the  Sponsors.  The Trustee is authorized to treat as the record
owner of Units that person who is  registered  as such owner on the books of the
Trustee.  Certificates  are  transferable by  presentation  and surrender to the
Trustee properly endorsed and accompanied by a written instrument or instruments
of transfer.

         Certificates may be issued in denominations of one Unit or any multiple
thereof. A Unit holder may be required to pay $2.00 per certificate  reissued or
transferred and to pay any governmental charge that may be imposed in connection
with each such transfer or interchange.  For new certificates  issued to replace
destroyed,  stolen or lost certificates,  the Unit holder must furnish indemnity
satisfactory to the Trustee and must pay such expenses as the Trustee may incur.
Mutilated certificates must be surrendered to the Trustee for replacement.

Distribution of Interest and Principal

         While interest will be distributed semi-annually or monthly,  depending
on the method of distribution chosen,  principal,  including capital gains, will
be distributed  only  semi-annually;  provided,  however,  that,  other than for
purposes of redemption,  no distribution need be made from the Principal Account
if the balance therein is less than $1.00 per Unit then  outstanding,  and that,
if at any  time  the pro  rata  share  represented  by the  Units of cash in the
Principal Account exceeds $10.00 as of a Monthly Record Date, the Trustee shall,
on the next succeeding Monthly  Distribution Date,  distribute the Unit holder's
pro rata share of the balance of the Principal Account.  Interest (semi-annually
or monthly) and  principal,  including  capital gains,  if any  (semi-annually),
received  by the Trust will be  distributed  on each  Distribution  Date to Unit
holders of record of the Trust as of the preceding  Record Date who are entitled
to such  distributions at that time under the plan of distribution  chosen.  All
distributions will be net of

279831.18
                                      -24-

<PAGE>



applicable expenses and funds required for the redemption of Units. See "Summary
of  Essential  Financial  Information"  in  Part  I  of  this  Prospectus,  "The
Trust--Expenses  and Charges" and "Rights of Unit  Holders--Redemption"  in Part
II.

         The  Trustee  will  credit to the  Interest  Account  for the Trust all
interest  received  by the Trust,  including  that part of the  proceeds  of any
disposition of Securities which represents  accrued interest.  Other receipts of
the Trust will be credited to the Principal  Account for the Trust. The pro rata
share of the Interest Account of the Trust and the pro rata share of cash in the
Principal Account of the Trust represented by each Unit thereof will be computed
by the Trustee  each month as of the Record  Date.  See  "Summary  of  Essential
Financial Information" in Part I of this Prospectus.  Proceeds received from the
disposition  of any of the  Securities  subsequent to a Record Date and prior to
the next succeeding  Distribution Date will be held in the Principal Account for
the Trust and will not be distributed until the second  succeeding  Distribution
Date.  Because  interest  on the  Securities  is not  received by the Trust at a
constant rate throughout the year, any particular  interest  distribution may be
more or less than the amount credited to the Interest Account of the Trust as of
the  Record  Date.  Persons  who  purchase  Units  between  a Record  Date and a
Distribution   Date  will  receive  their  first   distribution  on  the  second
Distribution Date following their purchase of Units under the applicable plan of
distribution.  No  distribution  need be made from the Principal  Account if the
balance therein is less than an amount sufficient to distribute $1.00 per Unit.

         The difference  between the estimated net interest accrued to the first
Record Date and to the related  Distribution  Date is an asset of the respective
Unit holder and will be realized in subsequent distributions or upon the earlier
of the sale of such Units or the  maturity,  redemption or sale of Securities in
the Trust.

         The plan of  distribution  selected  by a Unit  holder  will  remain in
effect until changed. Unit holders purchasing Units in the secondary market will
initially  receive  distributions  in accordance  with the election of the prior
owner.  Each  April,  the  Trustee  will  furnish  each Unit holder a card to be
returned together with the Certificate by May 15 of such year if the Unit holder
desires to change its plan of distribution, and the change will become effective
on May 16 of such  year for the  ensuing  twelve  months.  For a  discussion  of
redemption of Units, see "Rights of Unit Holders--Redemption-- Tender of Units."

         As of the  fifteenth day of each month the Trustee will deduct from the
Interest Account and, to the extent funds are not sufficient  therein,  from the
Principal Account,  amounts necessary to pay the expenses of the Trust as of the
first day of such month. See "The Trust--Expenses and Charges." The Trustee also
may withdraw from said accounts such amounts,  if any, as it deems  necessary to
establish  a reserve  for any  governmental  charges  payable  out of the 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 may withdraw  from the Interest
Account and the  Principal  Account  such  amounts as may be  necessary to cover
redemption  of Units by the Trustee.  See "Rights of Unit  Holders--Redemption."
Funds which are  available  for future  distributions,  payments of expenses and
redemptions are in accounts which are  non-interest  bearing to the Unit holders
and are available for use by the Trustee pursuant to normal banking procedures.


279831.18
                                      -25-

<PAGE>



         Because  interest  on  Securities  in the Trust is  payable  at varying
intervals,  usually in semi-annual  installments,  the interest  accruing to the
Trust will not be equal to the amount of money  received and  available  monthly
for distribution  from the Interest Account to Unit holders choosing the monthly
payment  plan.  Therefore,  on each  monthly  Distribution  Date,  the amount of
interest   actually   deposited  in  the  Interest  Account  and  available  for
distribution may be slightly more or less than the monthly interest distribution
made.  In  addition,  because  of the  varying  interest  payment  dates  of the
Securities  constituting the Trust  portfolio,  accrued interest at any point in
time will be greater than the amount of interest  actually received by the Trust
and distributed to Unit holders. Therefore, there will usually remain an item of
accrued interest that is added to the value of the Units. If a Unit holder sells
all or a portion of its Units, he will be entitled to receive its  proportionate
share of the accrued interest from the purchaser of its Units.  Similarly,  if a
Unit holder redeems all or a portion of its Units, the Redemption Price per Unit
which he is  entitled  to receive  from the Trustee  will also  include  accrued
interest on the Securities.  Thus, the accrued  interest  attributable to a Unit
will not be entirely  recovered  until the Unit holder  either  redeems or sells
such  Unit  or  until   the   Trust  is   terminated.   See   "Rights   of  Unit
Holders--Redemption--Computation of Redemption Price per Unit."

Expenses and Charges

         Initial Expenses

         All the expenses of creating and  establishing the Trust for Series 118
and prior  Series  have been borne by the  Sponsors,  including  the cost of the
initial  preparation,  printing  and  execution of the Trust  Agreement  and the
certificates  for Units,  legal  expenses,  advertising  and  selling  expenses,
expenses of the Trustee and other out-of-pocket expenses.

         All or a portion of the expenses  incurred in creating and establishing
the  Trust for  Series  119 and  subsequent  Series,  including  the cost of the
initial  preparation and execution of the Trust Agreement,  the initial fees and
expenses of the Trustee, legal expenses and other actual out-of-pocket expenses,
have been paid by the Trust.  For Series 119 through 140 such  expenses  will be
amortized  over a five year period.  Organizational  expenses for Series 141 and
subsequent  Series will be charged upon the investor's  purchase of Units during
the  initial  offering  period  and  will be paid at the  close  of the  initial
offering period by the Trust. All advertising and selling  expenses,  as well as
any organizational expenses not paid by the Trust, will be borne by the Sponsors
at no cost to the Trust.

         Fees

         The  Trustee's,  Sponsor's  and  Evaluator's  fees are set forth  under
"Summary of Essential Financial  Information" in Part I of this Prospectus.  The
Sponsors' fee, if any, which is earned for portfolio  supervisory  services,  is
based on the face amount of  Securities in the Trust at December 1 of each year.
The Sponsors'  fee,  which is not to exceed the maximum  amount set forth in the
"Summary of Essential Financial  Information" in Part I of this Prospectus,  may
exceed  the actual  costs of  providing  portfolio  supervisory  services  for a
particular Series, but at no time will the total amount received by the Sponsors
for  portfolio  supervisory  services  rendered  to all  Series of Empire  State
Municipal Exempt Trust in any calendar year exceed the aggregate cost to them of
supplying such services in such year.


279831.18
                                      -26-

<PAGE>



         The Trustee  will receive for its  ordinary  recurring  services to the
Trust an  annual  fee in the  amount  set  forth in the  "Summary  of  Essential
Financial  Information"  in Part I of this  Prospectus.  There is no minimum fee
and,  except as  hereinafter  set forth,  no maximum fee.  For a  discussion  of
certain  benefits  derived by the Trustee from the Trust's funds, see "Rights of
Unit  Holders--Distribution  of Interest and Principal." For a discussion of the
services  performed by the Trustee  pursuant to its obligations  under the Trust
Agreement,  reference is made to the  material  set forth under  "Rights of Unit
Holders."

         The Trustee's  and  Evaluator's  fees are payable  monthly on or before
each  Distribution  Date and the  Sponsors'  annual fee is payable  annually  on
December 1, each from the Interest Account to the extent funds are available and
then from the Principal Account. These fees may be increased without approval of
the Unit holders by amounts not  exceeding  proportionate  increases in consumer
prices for  services  as  measured by the United  States  Department  of Labor's
Consumer  Price Index  entitled "All Services Less Rent." If the balances in the
Principal and Interest  Accounts are insufficient to provide for amounts payable
by the Trust,  or amounts  payable to the Trustee which are secured by its prior
lien on the Trust, the Trustee is permitted to sell Bonds to pay such amounts.

         Insurance Premiums

         The cost of the  insurance  obtained  by the Trust as set  forth  under
"Summary of Essential  Financial  Information"  in Part I of this  Prospectus is
based on the  aggregate  amount  of  Bonds  in the  Trust as of the date of such
information.  The premium,  which is an obligation of each respective  Trust, is
payable  monthly by the  Trustee on behalf of the Trust.  As  Securities  in the
portfolio of the Trust mature,  are redeemed by their respective  issuers or are
sold by the  Trustee,  the amount of the  premium  will be reduced in respect of
those  Securities  no longer owned by and held in the Trust.  The Trust does not
incur any premium expense for any insurance which has been obtained by an issuer
of a Pre-insured  Bond,  since the premium or premiums for such  insurance  have
been  paid by such  issuer  or other  party;  Pre-insured  Bonds,  however,  are
additionally insured by the Trust. No premium will be paid by the Trust on Bonds
which  are also MBIA  Corp  Pre-insured  Bonds or MBIA  Pre-insured  Bonds.  The
premium  payable for Permanent  Insurance and the related  custodial fee will be
paid solely from the  proceeds of the sale of a Bond from the Trust in the event
that the Trustee exercises the right to obtain Permanent Insurance on such Bond.

         Other Charges

         The following  additional  charges are or may be incurred by the Trust:
all  expenses  (including  audit and counsel  fees) of the  Trustee  incurred in
connection with its activities under the Trust Agreement, including annual audit
expenses by independent public accountants  selected by the Sponsors (so long as
the  Sponsors  maintain a secondary  market,  the  Sponsors  will bear any audit
expense which  exceeds 50 cents per Unit),  the expenses and costs of any action
undertaken  by the Trustee to protect the Trust and the rights and  interests of
the Unit holders;  fees of the Trustee for any extraordinary  services performed
under  the  Trust  Agreement;  indemnification  of the  Trustee  for any loss or
liability  accruing  to it  without  willful  misconduct,  bad  faith  or  gross
negligence on its part,  arising out of or in connection  with its acceptance or
administration  of the  Trust;  and all  taxes and  other  governmental  charges
imposed upon the  Securities  or any part of the Trust (no such taxes or charges
are being levied or made or,

279831.18
                                      -27-

<PAGE>



to the knowledge of the Sponsors,  contemplated).  The above expenses, including
the Trustee's  fee, when paid by or owing to the Trustee,  are secured by a lien
on the Trust. In addition,  the Trustee is empowered to sell Securities in order
to make funds available to pay all expenses.

Reports and Records

         The Trustee shall furnish Unit holders of the Trust in connection  with
each distribution a statement of the amount of interest,  if any, and the amount
of other receipts,  if any, which are being distributed,  expressed in each case
as a dollar  amount  per Unit.  Within a  reasonable  time after the end of each
calendar  year,  the Trustee  will furnish to each person who at any time during
the  calendar  year was a Unit  holder  of  record  a  statement  providing  the
following  information:  (1)  as to  the  Interest  Account:  interest  received
(including  amounts  representing  interest  received  upon any  disposition  of
Securities and any earned original issue  discount),  and, if the issuers of the
Securities  are located in different  states or  territories,  the percentage of
such  interest  by  such  states  or  territories,  deductions  for  payment  of
applicable  taxes and for fees and  expenses of the Trust  (including  insurance
costs),  redemptions of Units 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;  (2) as to the  Principal  Account:  the  dates  of
disposition of any Securities and the net proceeds received therefrom (including
any unearned  original  issue  discount but excluding  any portion  representing
interest,  with respect to the Trust the premium  attributable  to the Trustee's
exercise of the right to obtain  Permanent  Insurance and any related  custodial
fee),  deductions for payments of applicable  taxes and for fees and expenses of
the  Trust,  redemptions  of Units,  the  amount of any "when  issued"  interest
treated  as  a  return  of  capital  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;  (3) a list of the Securities  held and
the number of Units  outstanding on the last business day of such calendar year;
(4) the Redemption price per Unit based upon the last  computation  thereof made
during such calendar  year;  and (5) 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.

         The Trustee shall keep available for inspection by Unit holders, at all
reasonable times during usual business hours, books of record and account of its
transactions  as Trustee  including  records of the names and  addresses of Unit
holders,  certificates  issued or held,  a  current  list of  Securities  in the
portfolio of the Trust and a copy of the Trust Agreement.

Redemption

         Tender of Units

         While it is anticipated that Units can be sold in the secondary market,
Units may also be tendered to the Trustee for redemption at its corporate  trust
office at 101 Barclay  Street,  New York,  New York 10286,  upon  payment of any
applicable  tax. At the present time there are no specific  taxes related to the
redemption of the Units.  No  redemption  fee will be charged by the Sponsors or
the Trustee. Units redeemed by the Trustee will be canceled.

279831.18
                                      -28-

<PAGE>



         Certificates  for Units to be redeemed must be delivered to the Trustee
and must be  properly  endorsed  and  accompanied  by a  written  instrument  of
transfer.  Thus,  redemption  of Units  cannot be  effected  until  certificates
representing  such Units have been delivered to the person  seeking  redemption.
See "Rights of Unit  Holders--Certificates."  Unit  holders must sign exactly as
their names appear on the face of the certificate with  signature(s)  guaranteed
by an officer of a national bank or trust  company,  a member firm of either the
New York,  Midwest or Pacific Stock Exchange,  or in such other manner as may be
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.

         By the third business day following  such tender,  the Unit holder will
be  entitled  to receive in cash an amount for each Unit  tendered  equal to the
Redemption Price per Unit computed as of the Evaluation Time set forth in Part I
of this Prospectus under "Summary of Essential Financial  Information" as of the
next  subsequent  Evaluation  Time. See  "Redemption--Computation  of Redemption
Price per Unit."  The "date of  tender" is deemed to be the date on which  Units
are received by the Trustee,  except that as regards  Units  received  after the
Evaluation Time on the New York Stock  Exchange,  the date of tender is the next
day on which such Exchange is open for trading or the next day on which there is
a  sufficient  degree of trading  in Units of the Trust,  and such Units will be
deemed to have been  tendered to the Trustee on such day for  redemption  at the
Redemption Price computed on that day. For information  relating to the purchase
by the  Sponsors of Units  tendered to the Trustee for  redemption  at prices in
excess of the Redemption  Price,  see  "Redemption--Purchase  by the Sponsors of
Units Tendered for Redemption."

         Accrued  interest  paid on  redemption  shall  be  withdrawn  from  the
Interest Account or, if the balance therein is insufficient,  from the Principal
Account.  All other  amounts  paid on  redemption  shall be  withdrawn  from the
Principal Account.  The Trustee is empowered to sell Securities in order to make
funds available for redemption.  Such sales, if required, could result in a sale
of Securities by the Trustee at a loss. To the extent  Securities  are sold, the
size and diversity of the Trust will be reduced.

         If the Trustee  exercises the right to obtain Permanent  Insurance on a
Bond,  such Bond will be sold from the Trust on an insured  basis.  In the event
that the Trustee does not exercise the right to obtain Permanent  Insurance on a
Bond,  such Bond will be sold from the  Trust on an  uninsured  basis  since the
insurance  obtained  by the Trust  covers the timely  payment of  principal  and
interest when due on the Bonds only while the Bonds are held in and owned by the
Trust. If the Trustee does not exercise the right to obtain Permanent  Insurance
on a  Defaulted  Bond,  to the extent that Bonds which are current in payment of
interest are sold from the Trust portfolio in order to meet redemption  requests
and  Defaulted  Bonds are  retained in the  portfolio  in order to preserve  the
related insurance protection  applicable to said Bonds, the overall value of the
Bonds    remaining    in   the    Trust    will    tend   to    diminish.    See
"Sponsors--Responsibility"  for the  effect of selling  Defaulted  Bonds to meet
redemption requests.

         The Trustee  reserves the right to suspend the right of redemption  and
to postpone the date of payment of the Redemption  Price per Unit for any period
during  which the New York Stock  Exchange  is closed,  other than  weekend  and
holiday  closings,  or during which  trading on that  Exchange is  restricted or
during which (as determined by the Securities and Exchange Commission by rule or
regulation) an emergency exists as a result of which disposal or

279831.18
                                      -29-

<PAGE>



evaluation of the underlying  Bonds is not reasonably  practicable,  or for such
other periods as the Securities and Exchange Commission has by order permitted.

         Because  insurance  obtained by the Trust  terminates as to Bonds which
are sold by the Trustee,  and because the  insurance  obtained by the Trust does
not have a  realizable  cash  value  which  can be used by the  Trustee  to meet
redemptions of Units (assuming,  in the case of Series 18 and subsequent Series,
that the Trustee does not exercise  the right to obtain  Permanent  Insurance on
Defaulted  Bonds),  under  certain  circumstances  the Sponsors may apply to the
Securities  and Exchange  Commission  for an order  permitting a full or partial
suspension  of the right of Unit holders to redeem their Units if a  significant
portion of the Bonds in the  portfolio  is in default in payment of principal or
interest or in significant risk of such default. No assurances can be given that
the Securities and Exchange  Commission  will permit the Sponsors to suspend the
rights of Unit holders to redeem their Units,  and,  without the  suspension  of
such redemption rights when faced with excessive  redemptions,  the Sponsors may
not be able to  preserve  the  benefits of the Trust's  insurance  on  Defaulted
Bonds.

         Computation of Redemption Price Per Unit

         The Redemption Price per Unit is determined by the Trustee on the basis
of the bid prices of the  Securities  in the Trust,  as of the  Evaluation  Time
stated under  "Summary of  Essential  Financial  Information"  in Part I of this
Prospectus on the day any such  determination  is made. The Redemption Price per
Unit is each  Unit's  pro rata  share,  determined  by the  Trustee,  of (1) the
aggregate  value of the Securities in the Trust  (determined by the Evaluator as
set forth  below),  except for those cases in which the value of  insurance  has
been  included,  (2)  cash on hand in the  Trust,  and (3)  accrued  and  unpaid
interest  on the  Securities  as of the date of  computation,  less (a)  amounts
representing  taxes or governmental  charges  payable out of the Trust,  (b) the
accrued  expenses  of the  Trust,  and (c) cash  held for  distribution  to Unit
holders  of record  as of a date  prior to the  evaluation.  The  Evaluator  may
determine  the value of the  Securities in the Trust (i) on the basis of current
bid prices for the  Securities,  (ii) if bid  prices are not  available  for any
Securities,  on the basis of current bid prices for comparable  bonds,  (iii) by
appraisal,  or  (iv)  by  any  combination  of the  above.  In  determining  the
Redemption Price per Unit, no value will be assigned to the portfolio  insurance
obtained by the Trust on the Bonds in the Trust unless such Bonds are in default
in payment of principal or interest or in significant  risk of such default.  On
the other hand,  Pre-insured Bonds in the Trust are entitled at all times to the
benefits  of  insurance  obtained  by their  respective  issuers  so long as the
Pre-insured  Bonds are  outstanding  and the  insurer  continues  to fulfill its
obligations, and such benefits are reflected and included in the market value of
Pre-insured  Bonds.  For a description  of the situations in which the Evaluator
may value the insurance obtained by the Trust, see "Public  Offering--Market for
Units."

         Purchase by the Sponsors of Units Tendered for Redemption

         The Trust  Agreement  requires that the Trustee  notify the Sponsors of
any tender of Units for  redemption.  So long as the Sponsors are  maintaining a
bid in the secondary market, the Sponsors, prior to the close of business on the
second succeeding  business day, will purchase any Units tendered to the Trustee
for redemption at the price so bid by making payment therefor to the Unit holder
in an amount not less than the Redemption  Price on the date of tender not later
than the day on which the Units would otherwise

                                      -30-

<PAGE>



have been  redeemed by the  Trustee.  See "Public  Offering--Market  for Units."
Units held by the Sponsors may be tendered to the Trustee for  redemption as any
other Units, provided that the Sponsors shall not receive for Units purchased as
set forth above a higher price than they paid, plus accrued interest.

         The  offering  price of any Units  resold by the  Sponsors  will be the
Public Offering Price determined in the manner provided in this Prospectus.  See
"Public Offering-- Offering Price." Any profit resulting from the resale of such
Units will belong to the Sponsors  which  likewise will bear any loss  resulting
from a lower  offering or redemption  price  subsequent to their  acquisition of
such Units.

Exchange Option

         The  Sponsors  of the Series of Empire  State  Municipal  Exempt  Trust
(including the Series of Municipal Exempt Trust, the predecessor trust to Empire
State  Municipal  Exempt Trust) (the "Trust") are offering Unit holders of those
Series of the Trust for which the Sponsors are maintaining a secondary market an
option to  exchange a Unit of any Series of the Trust for a Unit of a  different
Series of the Trust  being  offered by the  Sponsors  (other than in the initial
offering period) at a Public Offering Price generally based on the bid prices of
the  underlying  Securities  divided  by the  number of Units  outstanding  (see
"Public  Offering--Market  for Units") plus a fixed sales charge of $15 per Unit
(in lieu of the normal sales charge).  However, a Unit holder must have held its
Unit for a period  of at least  six  months in order to  exercise  the  exchange
option or agree to pay a sales charge based on the greater of $15 per Unit or an
amount which together with the initial sales charge paid in connection  with the
acquisition  of Units  being  exchanged  equals the normal  sales  charge of the
Series into which the investment is being  converted,  determined as of the date
of the exchange. Such exchanges will be effected in whole Units only. Any excess
proceeds from the Units being surrendered will be returned,  and the Unit holder
will not be permitted to advance any new money in order to complete an exchange.
The Sponsors reserve the right to modify,  suspend or terminate this plan at any
time without further notice to the Unit holders.  In the event that the exchange
option is not  available  to a Unit holder at the time he wishes to exercise it,
the Unit holder will be  immediately  notified  and no action will be taken with
respect to its Units without further instructions from the Unit holder.

         Unit  holders  are urged to consult  their tax  advisors  as to the tax
consequences of exchanging Units.

                         AUTOMATIC ACCUMULATION ACCOUNT


         The Sponsors have entered into an arrangement  (the "Plan") with Empire
Builder Tax Free Bond Fund (the "Empire  Builder") which permits Unit holders of
the Trust to elect to have distributions  from Units in the Trust  automatically
reinvested in shares of the Empire  Builder.  The Empire Builder is an open-end,
non-diversified investment company whose investment objective is to seek as high
a level of current income exempt from regular Federal income tax, New York State
and New York City  personal  income taxes as is believed to be  consistent  with
preservation  of  capital.  It is the  policy of the  Empire  Builder  to invest
primarily in debt  securities the interest income from which is exempt from such
taxes.

         The Empire Builder has an investment objective which differs in certain
respects from that of the Trust.  The bonds purchased by the Empire Builder will
be of  "investment  grade"  quality  - that is, at the time of  purchase  by the
Empire Builder,  such bonds either will be rated not lower than the four highest
ratings of either  Moody's (Aaa, Aa, A or Baa) or Standard & Poor's (AAA, AA, A,
or BBB) or will be unrated bonds which at the time of purchase are judged by the
Empire Builder's  investment  advisor to be of comparable quality to bonds rated
within  such four  highest  grades.  It is a  fundamental  policy of the  Empire
Builder  that  under  normal  market  conditions  at  least  90% of  the  income
distributed to its shareholders  will be exempt from regular Federal income tax,
New York State and New York City personal income taxes. However, during times of
adverse  market  conditions  when the Empire  Builder is investing for temporary
defensive  purposes in obligations  other than New York tax-exempt  bonds,  more
than 10% of the  Empire  Builder's  income  distributions  could be  subject  to
Federal  income tax,  New York State income tax and/or New York City income tax,
as  described  in the current  prospectus  relating to the Empire  Builder  (the
"Empire Builder Prospectus").  Glickenhaus & Co.  ("Glickenhaus"),  a sponsor of
the  Trust,  acts as the  investment  advisor  and  distributor  for the  Empire
Builder.


         Each Unit  holder  may  request  from The Bank of New York  (the  "Plan
Agent") a copy of the Empire  Builder  Prospectus  describing the Empire Builder
and a form by  which  such  Unit  holder  may  elect  to  become  a  participant
("Participant")   in  the  Plan.   Thereafter,   as  directed  by  such  person,
distributions on the  Participant's  Units will, on the applicable  Distribution
Date, automatically be applied as of that date by the Trustee to purchase shares
(or fractions thereof) of the Empire Builder at a net asset value as computed as
of the  close of  trading  on the New  York  Stock  Exchange  on such  date,  as
described in the Empire Builder  Prospectus.  Unless  otherwise  indicated,  new
Participants  in the  Empire  Builder  Plan will be deemed to have  elected  the
monthly  distribution  plan with  respect to their Units.  Confirmations  of all
transactions  undertaken for each Participant in the Plan will be mailed to each
such  Participant  by the Plan  Agent  indicating  distributions  and shares (or
fractions  thereof) of the Empire Builder purchased on its behalf. A Participant
may at any time prior to ten days  preceding  the next  succeeding  distribution
date,  by so  notifying  the Plan  Agent in  writing,  elect  to  terminate  its
participation in the Plan and receive future distributions on its Units in cash.
There will be no charge or other penalty for such termination. The Sponsors, the
Trustee,  the Empire Builder and Glickenhaus,  as investment  advisor for Empire
Builder  each  will have the  right to  terminate  this Plan at any time for any
reason.  The reinvestment of distributions  from the Trust through the Plan will
not  affect  the income  tax  status of such  distributions.  For more  complete
information  about investing in the Empire Builder  through the Plan,  including
charges and expenses,  request a copy of the Empire Builder  Prospectus from The
Bank of New York,  Unit  Investment  Trust,  P.O.  Box 972,  New York,  New York

                         AUTOMATIC ACCUMULATION ACCOUNT

         For Unit holders of the Trust who are clients of Lebenthal & Co., Inc.,
the Sponsors have entered into an  arrangement  (the "Plan") with  Lebenthal New
York  Municipal  Bond Fund (the "Bond Fund")  which  permits Unit holders of the
Trust who receive  distributions  from the Trust on a semi-annual basis to elect
to have distributions from Units in the Trust automatically reinvested in shares
of the Bond  Fund.  The Bond  Fund is an  open-end,  non-diversified  investment
company whose  investment  objective is to maximize  current  income exempt from
regular  Federal  income  tax,  and from New York State and New York City income
taxes,  consistent with preservation of capital and with consideration  given to
opportunities  for  capital  gain.  It is the  policy of the Bond Fund to invest
primarily  in long term  investment  grade  tax-exempt  securities  the interest
income from which is exempt from such taxes.

         The Bond Fund has an  investment  objective  which  differs  in certain
respects from that of the Trust. The bonds purchased by the Bond Fund will be of
"investment grade" quality -- that is, at the time of purchase by the Bond Fund,
such  bonds  either  will be rated not lower  than the four  highest  ratings of
either  Moody's  (Aaa,  Aa, A or Baa) or Standard & Poor's (AAA, A, A or BBB) or
will be  unrated  bonds  which at the time of  purchase  are  judged by the Bond
Fund's investment advisor to be of comparable quality to bonds rated within such
four  highest  grades.  It is a  fundamental  policy of the Bond Fund that under
normal  market  conditions  at  least  80%  of  the  income  distributed  to its
shareholders  will be exempt from regular  Federal income tax, and from New York
State and New York City personal income taxes. However,  during times of adverse
market conditions,  more than 20% of the Bond Fund's income  distributions could
be subject to Federal  income  tax,  New York State  and/or New York City income
taxes,  as  described in the current  prospectus  relating to the Bond Fund (the
"Bond Fund Prospectus").  Lebenthal & Co., Inc., a sponsor of the Trust, acts as
the manager and distributor for the Bond Fund.

         Each  Unit  holder  who  receives  distributions  from  the  Trust on a
semi-annual  basis may  request  from The Bank of New York (the "Plan  Agent") a
copy of the Bond Fund  Prospectus  describing  the Bond Fund and a form by which
such Unit holder may elect to become a participant  ("Participant") in the Plan.
Thereafter, as directed by such person,  distributions on the Participant's Unit
will, on the applicable  Distribution Date,  automatically be applied as of that
date by the Trustee to purchase  shares (or fractions  thereof) of the Bond Fund
at a net asset  value as  computed  as of the close of  trading  on the New York
Stock  Exchange on such date, as described in the Bond Fund  Prospectus.  Unless
otherwise  indicated,  new  Participants in the Bond Fund Plan will be deemed to
have  elected  the  monthly  distribution  plan  with  respect  to their  Units.
Confirmations  of all  transactions  undertaken for each Participant in the Plan
will be mailed to each  Participant by the Plan Agent  indicating  distributions
and shares (or fractions  thereof) of the Bond Fund  purchased on its behalf.  A
Participant  may at any time  prior to ten days  preceding  the next  succeeding
distribution date, by so notifying the Plan Agent in writing, elect to terminate
its  participation in the Plan and receive future  distributions on its Units in
cash.  There  will be no  charge  or other  penalty  for such  termination.  The
Sponsors,  the Trustee,  the Bond Fund and  Lebenthal & Co. Inc., as manager for
the Bond Fund,  each will have the right to terminate or modify this Plan at any
time for any reason.  The reinvestment of  distributions  from the Trust through
the Plan will not affect the income tax status of such  distributions.  For more

                                    SPONSORS

         Glickenhaus  and Lebenthal are the Sponsors for Empire State  Municipal
Exempt Trust,  Series 10 and all  subsequent  Series,  including all  Guaranteed
Series.

         Glickenhaus,  a  New  York  limited  partnership,  is  engaged  in  the
underwriting and securities  brokerage  business and in the investment  advisory
business.  It is a member of the New York Stock Exchange,  Inc. and the National

York Series 2 and New York Series 3.  Glickenhaus,  in addition to participating

Limitations on Liability

         The Sponsors are jointly and severally  liable for the  performance  of
their obligations arising from their responsibilities under the Trust Agreement,
but will be under no  liability  to the Unit  holders  for  taking any action or
refraining  from any action in good faith or for  errors in  judgment;  nor will
they be  responsible in any way for  depreciation  or loss incurred by reason of
the sale of any Bonds, except in cases of their willful misconduct, bad faith or
gross negligence. See "The Trust--Portfolio" and "Sponsors--Responsibility."

Responsibility

         The Trustee shall sell, for the purpose of redeeming  Units tendered by
any Unit  holder,  and for the  payment of  expenses  for which funds may not be
available,  such of the Bonds in a list furnished by the Sponsors as the Trustee
in its sole  discretion may deem  necessary.  In the event that the Trustee does
not exercise  the right to obtain  Permanent  Insurance  on a Defaulted  Bond or
Bonds,  to the  extent  that  Bonds are sold  which are  current  in  payment of
principal and interest in order to meet redemption  requests and Defaulted Bonds
are  retained  in the  portfolio  in order to  preserve  the  related  insurance
protection applicable to said Bonds, the overall value of the Bonds remaining in
the Trust's  portfolio  will tend to  diminish.  As to Series 18 and  subsequent
Series, in the event that the Trustee does not exercise the right

279831.18
                                      -33-

<PAGE>



to obtain Permanent  Insurance on a Defaulted Bond or Bonds, except as described
below and in certain other unusual  circumstances  for which it is determined by
the Trustee to be in the best  interests  of the Unit  holders or if there is no
alternative,  the Trustee is not  empowered  to sell  Defaulted  Bonds for which
value has been  attributed for the insurance  obtained by the Trust.  Because of
such restrictions on the Trustee,  under certain  circumstances the Sponsors may
seek a full or partial  suspension  of the right of Unit holders to redeem their
Units. See "Rights of Unit Holders--Redemption." The Sponsors are empowered, but
not obligated, to direct the Trustee to dispose of Bonds in the event of advance
refunding.  It is the  responsibility of the Sponsors to instruct the Trustee to
reject  any  offer  made by an  issuer  of any of the  Securities  to issue  new
obligations  in  exchange  and  substitution  for any  Securities  pursuant to a
refunding or refinancing plan, except that the Sponsors may instruct the Trustee
to accept such an offer or to take any other action with respect  thereto as the
Sponsors  may deem  proper if the  issuer is in  default  with  respect  to such
Securities or in the judgment of the Sponsors the issuer will  probably  default
with respect to such Securities in the foreseeable future.

         Any obligations so received in exchange or substitution will be held by
the Trustee  subject to the terms and  conditions of the Trust  Agreement to the
same extent as  Securities  originally  deposited  thereunder.  Within five days
after the deposit of  obligations  in exchange or  substitution  for  underlying
Securities,  the Trustee is required to give notice thereof to each Unit holder,
identifying the obligations  eliminated and the Securities substituted therefor.
Except as stated in this and the preceding  paragraph,  the  acquisition  by the
Trust  of any  securities  other  than the  Securities  initially  deposited  is
prohibited.

         If any  default in the  payment of  principal  or  interest on any Bond
occurs and no  provision  for payment is made  therefor  either  pursuant to the
portfolio  insurance with respect to the Trust or otherwise  within 30 days, the
Trustee is required to notify the  Sponsors  thereof.  If the  Sponsors  fail to
instruct  the  Trustee  to  sell or to  hold  such  Bond  within  30 days  after
notification by the Trustee to the Sponsors of such default,  the Trustee may in
its discretion sell the Defaulted Bond and not be liable for any depreciation or
loss thereby incurred. See "The Trust--Insurance on the Bonds."

         The Sponsors may direct the Trustee to dispose of Bonds upon default in
the payment of principal or interest,  institution of certain legal  proceedings
or the existence of certain other  impediments to the payment of Bonds,  default
under other  documents which may adversely  affect debt service,  default in the
payment of  principal  or  interest  on other  obligations  of the same  issuer,
decline in  projected  income  pledged  for debt  service on revenue  Bonds,  or
decline in price or the occurrence of other market  factors,  including  advance
refunding, so that in the opinion of the Sponsors the retention of such Bonds in
a Trust would be detrimental  to the interest of the Unit holders.  The proceeds
from any such sales will be credited to the  Principal  Account of the  affected
Trust for distribution to the Unit holders.

         Notwithstanding  the foregoing,  in connection with final distributions
to Unit holders,  if the Trustee does not exercise the right to obtain Permanent
Insurance on any Defaulted Bond, because the portfolio insurance obtained by the
Trust is applicable only while Bonds so insured are held by the Trust, the price
to be received by the Trust upon the disposition of any such Defaulted Bond will
not reflect any value based on such insurance. Therefore, in connection with any
liquidation with respect to a Trust, it

279831.18
                                      -34-

<PAGE>



shall not be necessary  for the Trustee to, and the Trustee  does not  currently
intend to, dispose of any Bonds if retention of such Bonds,  until due, shall be
deemed to be in the best  interest of Unit holders,  including,  but not limited
to,  situations in which Bonds so insured are in default and situations in which
Bonds so insured have a deteriorated  market price  resulting from a significant
risk of  default.  Since the  Pre-insured  Bonds will  reflect  the value of the
insurance  obtained  by the Bond  issuer,  it is the  present  intention  of the
Sponsors not to direct the Trustee to hold any Pre- insured Bonds after the date
of termination.  All proceeds received, less applicable expenses, from insurance
on Defaulted Bonds not disposed of at the date of termination will ultimately be
distributed  to Unit holders of record as of such date of termination as soon as
practicable  after the date  such  Defaulted  Bonds  become  due and  applicable
insurance proceeds have been received by the Trustee.  See "Summary of Essential
Financial Information" in Part I of this Prospectus.

Agent for Sponsors

         The Sponsor  named as Agent for  Sponsors  under  "Summary of Essential
Information"  in Part I of this  Prospectus  has  been  appointed  by the  other
Sponsor as agent for  purposes of taking  action under the Trust  Agreement.  In
those Trusts for which there is a sole Sponsor,  references  herein to the Agent
for Sponsors shall be deemed to refer to such sole Sponsor.  If the Sponsors are
unable to agree  with  respect  to action to be taken  jointly by them under the
Trust  Agreement  and they cannot  agree as to which  Sponsor  shall act as sole
Sponsor,  then the Agent for Sponsors  shall act as sole Sponsor.  If one of the
Sponsors  fails to  perform  its  duties  under the Trust  Agreement  or becomes
incapable of acting or becomes  bankrupt or its affairs are taken over by public
authorities,  that Sponsor is automatically discharged under the Trust Agreement
and the other Sponsor acts as the Sponsors.

Resignation

         Any  Sponsor may resign at any time  provided  that at the time of such
resignation  one remaining  Sponsor  maintains a net worth of $1,000,000 and all
the remaining  Sponsors are agreeable to such  resignation.  Concurrent  with or
subsequent to such resignation,  a new Sponsor may be appointed by the remaining
Sponsors and the Trustee to assume the duties of the resigning  Sponsor.  If, at
any time,  only one Sponsor is acting under the Trust Agreement and that Sponsor
shall  resign  or  fail to  perform  any of its  duties  thereunder  or  becomes
incapable of acting or becomes  bankrupt or its affairs are taken over by public
authorities,  then the Trustee may appoint a successor  sponsor or terminate the
Trust Agreement and liquidate the Trust.

Financial Information

         At September 30, 1998, the total  partners'  capital of Glickenhaus was
$185,620,531 (audited); and at March 31, 1999, the total stockholders' equity of
Lebenthal was $6,269,873 (audited).

         The foregoing  information  with regard to the Sponsors  relates to the
Sponsors  only,  and not to any series of Empire State  Municipal  Exempt Trust.
Such  information  is  included  in this  Prospectus  only  for the  purpose  of
informing investors as to the financial responsibility of the Sponsors and their
ability  to  carry  out  their  contractual   obligations  shown  herein.   More
comprehensive  financial  information  can be  obtained  upon  request  from any
Sponsor.

                                     TRUSTEE

         The Trustee is The Bank of New York, a trust  company  organized  under
the laws of New York,  having its offices at 101 Barclay  Street,  New York, New
York 10286,  (800) 221-7771.  The Bank of New York is subject to supervision and
examination  by the  Superintendent  of Banks  of the  State of New York and the
Board of Governors of the Federal Reserve  System,  and its deposits are insured
by the Federal Deposit Insurance Corporation to the extent permitted by law. The
Trustee must be a corporation  organized  under the laws of the United States or
the State of New York, which is authorized under such laws to exercise corporate
trust  powers,  and must have at all times an  aggregate  capital,  surplus  and
undivided profits of not less than $5,000,000 and its principal office and place
of  business  in the  Borough of  Manhattan,  New York  City.  The duties of the
Trustee are primarily  ministerial in nature. The Trustee did not participate in
the selection of Securities for the portfolio of any Series of the Trust.

Limitations on Liability

         The  Trustee  shall  not  be  liable  or  responsible  in any  way  for
depreciation  or loss  incurred  by reason  of the  disposition  of any  moneys,
Securities  or  certificates  or in respect of any  evaluation or for any action
taken in good faith reliance on prima facie properly  executed  documents except
in cases of its willful  misconduct,  bad faith,  gross  negligence  or reckless
disregard for its obligations and duties. In addition,  the Trustee shall not be
personally liable for any taxes or other governmental charges imposed upon or in
respect of the Trust which the  Trustee may be required to pay under  current or
future  law  of  the  United  States  or  any  other  taxing   authority  having
jurisdiction. See "The Trust--Portfolio."

Responsibility

         For information  relating to the  responsibilities of the Trustee under
the Trust  Agreement,  reference is made to the material set forth under "Rights
of Unit Holders," "Sponsors--Responsibility" and "Sponsors-- Resignation."

Resignation

         By  executing  an  instrument  in writing  and filing the same with the
Sponsors,  the  Trustee  and any  successor  may  resign.  In such an event  the
Sponsors are  obligated to appoint a successor  trustee as soon as possible.  If
the Trustee becomes  incapable of acting or becomes  bankrupt or its affairs are
taken over by public  authorities,  or, in the case of Series 11 and  subsequent
Series,  if the Sponsors deem it to be in the best interest of the Unit holders,
the  Sponsors  may remove the Trustee and appoint a successor as provided in the
Trust  Agreement.  Such  resignation or removal shall become  effective upon the
acceptance of  appointment  by the successor  trustee.  If, upon  resignation or
removal of a trustee,  no  successor  has been  appointed  and has  accepted the
appointment  within  thirty days after  notification,  the retiring  trustee may
apply to a court of competent  jurisdiction  for the appointment of a successor.
The  resignation  or  removal  of a  trustee  becomes  effective  only  when the
successor  trustee  accepts its appointment as such or when a court of competent
jurisdiction appoints a successor trustee.

<PAGE>



                                    EVALUATOR

         The Evaluator is Muller Data Corporation, a New York corporation,  with
main  offices  at 395 Hudson  Street,  New York,  New York  10014.  Muller  Data
Corporation is a wholly owned subsidiary of Thomson  Publishing  Corporation,  a
Delaware corporation.

Limitations on Liability

         The Trustee and the  Sponsors may rely on any  evaluation  furnished by
the  Evaluator  and  shall  have no  responsibility  for the  accuracy  thereof.
Determinations  by the Evaluator under the Trust Agreement shall be made in good
faith upon the basis of the best information available to it; provided, however,
that the Evaluator  shall be under no liability to the Trustee,  the Sponsors or
the Unit holders for errors in judgement.  This provision  shall not protect the
Evaluator in cases of its willful  misconduct,  bad faith,  gross  negligence or
reckless disregard of its obligations and duties.

Responsibility

         The Trust  Agreement  requires the Evaluator to evaluate the Securities
on the basis of their bid prices on each business day after the initial offering
period,  when any Unit is  tendered  for  redemption  and on any  other day such
evaluation  is  desired by the  Trustee or is  requested  by the  Sponsors.  For
information  relating to the  responsibility  of the  Evaluator  to evaluate the
Securities on the basis of their offering prices, see "Public Offering--Offering
Price."

Resignation

         The  Evaluator  may resign or may be removed  by the  Sponsors  and the
Trustee,  and the  Sponsors  and the  Trustee  are to use their best  efforts to
appoint a  satisfactory  successor.  Such  resignation  or removal  shall become
effective upon the acceptance of appointment by the successor evaluator. If upon
resignation of the Evaluator no successor has accepted appointment within thirty
days  after  notice  of  resignation,  the  Evaluator  may  apply  to a court of
competent jurisdiction for the appointment of a successor.


                AMENDMENT AND TERMINATION OF THE TRUST AGREEMENT

         The  Sponsors  and the  Trustee  have  the  power to  amend  the  Trust
Agreement  without the consent of any of the Unit holders when such an amendment
is (1) to cure any  ambiguity or to correct or  supplement  any provision of the
Trust Agreement which may be defective or inconsistent  with any other provision
contained  therein,  or (2) to make such other provisions as shall not adversely
affect the  interest of the Unit  holders;  and the Sponsors and the Trustee may
amend the Trust  Agreement  with the  consent  of the  holders  of  certificates
evidencing  66-2/3%  of the  Units  then  outstanding,  provided  that  no  such
amendment  will reduce the  interest  in a Trust of any Unit holder  without the
consent  of such Unit  holder or reduce  the  percentage  of Units  required  to
consent to any such amendment without the consent of all the Unit holders. In no
event  shall the Trust  Agreement  be  amended to  increase  the number of Units
issuable thereunder or to permit the deposit or acquisition of securities either
in addition to or in substitution  for any of the Bonds  initially  deposited in
the Trust,  except in accordance with the provisions of the Trust Agreement.  In
the event of any amendment, the Trustee is obligated to notify promptly all Unit
holders of the substance of such amendment.

         The Trust shall terminate upon the maturity,  redemption, sale or other
disposition,  as the case may be,  of the last of the  Securities.  The  Trustee
shall  notify  all  Unit  holders  when the  value of the  Trust as shown by any
evaluation is less than $2,000,000 or less than 20% of the value of the Trust as
of the Date of  Deposit,  whichever  is  lower,  at which  time the Trust may be
terminated  (i) by the consent of the holders of 66-2/3% of the Units or (ii) by
the Trustee;  provided,  however,  that upon affirmative written notice of their
opportunity to object to such termination and to the Sponsors and the holders of
at least  33-1/3% of the Units do not instruct the Trustee not to terminate  the
Trust.  In no  event,  however,  may the Trust  continue  beyond  the  Mandatory
Termination  Date  set  forth in Part I of this  Prospectus  under  "Summary  of
Essential Financial Information"; provided, however, that prior to the Mandatory
Termination  Date the Trustee shall not dispose of any Bonds if the retention of
such Bonds,  until due,  shall be deemed to be in the best  interest of the Unit
holders of the  affected  Trust.  In the event of  termination,  written  notice
thereof  will be sent by the Trustee to all Unit  holders.  Within a  reasonable
period after  termination,  the Trustee will sell any remaining  Securities and,
after paying all expenses and charges incurred by the Trust,  will distribute to
each Unit holder,  upon surrender for cancellation of its certificate for Units,
its pro rata share of the  balances  remaining  in the  Interest  and  Principal
Accounts of the Trust.

                           DESCRIPTION OF BOND RATINGS

         A Standard & Poor's  corporate  or  municipal  bond rating is a current
assessment  of the  creditworthiness  of an obligor  with  respect to a specific
obligation.  This  assessment of  creditworthiness  may take into  consideration
obligors  such as  guarantors,  insurers  or  lessees.  The bond 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  to Standard &
Poor's by the issuer and  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.

279831.18
                                      -38-

<PAGE>



The ratings may be changed, suspended or withdrawn as a result of changes in, or
unavailability of, such information or for other circumstances.

         The  ratings  are  based,   in  varying   degrees,   on  the  following
considerations:

         I.  Likelihood of default - capacity and  willingness of the obligor as
to the timely payment of interest and repayment of principal in accordance  with
the terms of the obligation;

         II. Nature of and provisions of the obligation;

         III.  Protection  afforded by, and relative position of, the obligation
in the event of bankruptcy,  reorganization  or other arrangement under the laws
of bankruptcy and other laws affecting creditors' rights.

                   AAA:  Bonds rated "AAA" have 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 higher rated categories.

                   BB, B, CCC,  CC:  Bonds  rated  "BB," "B," "CCC" and "CC" are
          regarded,  on balance,  as  predominantly  speculative with respect to
          capacity to pay interest and repay  principal in  accordance  with the
          terms  of  the  obligation.   "BB"  indicates  the  lowest  degree  of
          speculation  and "CC" the highest  degree of  speculation.  While such
          bonds will likely have some  quality and  protective  characteristics,
          these are outweighed by large uncertainties or major risk exposures to
          adverse conditions.

                   Plus (+) or Minus (-): To provide more  detailed  indications
          of credit quality, the ratings from "AA" to "B" 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 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

279831.18
                                      -39-

<PAGE>



           upon failure of, such  completion.  Accordingly,  the investor should
           exercise its own judgment with respect to such likelihood and risk.

                   NO:  Indicates that no rating has been requested,  that there
          is insufficient information on which to base a rating or that Standard
          & Poor's does not rate a particular  type of obligation as a matter of
          policy.

                   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.

                   SP-3: Speculative capacity to pay principal and interest.

*Moody's rating.  A summary of the meaning of the applicable rating symbols as
published by Moody's 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.

                   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 fluctuation of protective elements may be of
          greater  amplitude or there may be other  elements  present which make
          the long-term risks appear somewhat larger than in "Aaa" securities.

                   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.

                   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.

                   Ba: Bonds which are rated "Ba" are judged to have speculative
          elements; their future cannot be considered as well assured. Often the
          protection of interest and principal payments may be very moderate and
          thereby not well  safeguarded  during both good and bad times over the
          future. Uncertainty of position characterizes bonds in this class.

279831.18
                                      -40-

<PAGE>



                   B: Bonds which are rated "B" generally  lack  characteristics
          of the  desirable  investment.  Assurance  of interest  and  principal
          payments or  maintenance  of other terms of the contract over any long
          period of time may be small.

                   Con.(...):  Bonds  for which the  security  depends  upon the
          completion of some act or the  fulfillment of some condition are rated
          conditionally.  These  bonds are  secured by (a)  earnings of projects
          under  construction,  (b) earnings of projects unseasoned in operating
          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.

Moody's   applies   numerical   modifiers  "1,"  "2"  and  "3"  in  each  rating
classification  from  "Aa"  through  "B" in its  corporate  rating  system.  The
modifier "1" indicates  that the security ranks in the higher end of its generic
rating  category;  the  modifier  "2"  indicates  a mid-range  ranking;  and the
modifier "3" indicates  that the security  ranks in the lower end of its generic
rating category.
