10,000 UNITS
          INVESTORS SHOULD READ AND RETAIN THIS PROSPECTUS FOR FUTURE REFERENCE.
 
IN THE OPINION OF COUNSEL UNDER EXISTING LAW, INTEREST INCOME TO THE TRUSTS AND
TO UNIT HOLDERS (EXCEPT IN CERTAIN INSTANCES DEPENDING UPON THE UNIT HOLDERS)
IS EXEMPT FROM REGULAR FEDERAL INCOME TAX AND FROM CERTAIN STATE AND LOCAL
PERSONAL INCOME TAXES, TO THE EXTENT INDICATED, IN THE STATE FOR WHICH A STATE
TRUST IS NAMED. CAPITAL GAINS, IF ANY, ARE SUBJECT TO TAX.
 
THE TAX EXEMPT SECURITIES TRUST consists of separate underlying unit investment
trusts designated as National Trust 228 and Maryland Trust 101 (the "National
Trust" and the "Maryland Trust," respectively) (the "Trusts" or the "Trust" as
the context requires and in the case of a Trust designated by a state name, the
"State Trust" or the "State Trusts," as the context requires). Each Trust was
formed to obtain for its Unit holders tax-exempt interest income and
conservation of capital through investment in a professionally selected, fixed
portfolio of municipal bonds rated at the time of deposit in the category A or
better by Standard & Poor's Ratings Group, a division of McGraw-Hill, Inc.
("Standard & Poor's"), Moody's Investors Service, Inc. ("Moody's"), Fitch
Investors Service, Inc. ("Fitch") or Duff & Phelps Credit Rating Co. ("Duff &
Phelps"). (See "Portfolio of Securities".) Each State Trust comprises a fixed
portfolio of interest-bearing obligations issued primarily by or on behalf of
the state for which such State Trust is named and counties, municipalities,
authorities or political subdivisions thereof. Interest on all bonds in each
Trust is in the opinion of counsel under existing law, with certain exceptions,
exempt from regular Federal income taxes (see Part B, "Taxes") and from certain
state and local personal income taxes in the state for which a State Trust is
named, but may be subject to other state and local taxes. (See discussions of
State and local taxes in Part C.)
 
THE PUBLIC OFFERING PRICE of the Units of each Trust during the initial public
offering period is equal to the aggregate offering price of the underlying
bonds in the Trust's portfolio divided by the number of Units outstanding in
such Trust, plus a sales charge. The Public Offering Price of the Units of each
Trust following the initial public offering period is equal to the aggregate
bid price of the underlying bonds in the Trust's portfolio divided by the
number of Units outstanding in such Trust, plus a sales charge. During the
initial public offering period the sales charge is equal to 4.70% of the Public
Offering Price (4.932% of the aggregate offering price of the bonds per Unit)
for each Trust, and following the initial public offering period this charge
will be equal to 5.00% of the Public Offering Price (5.263% of the aggregate
bid price of the bonds per Unit) for each Trust. See Part B, "Public Offering--
Distribution of Units" for a description of the initial public offering period.
If the Units had been available for sale on December 10, 1997, the Public
Offering Price per Unit (including the sales charge) would have been $1,042.39
and $1,051.39 for the National Trust and Maryland Trust respectively. In
addition, there will be added an amount equal to accrued interest commencing on
the day after the Date of Deposit through the date of settlement (normally
three business days after purchase).
 
THE SPONSOR, although not obligated to do so, intends to maintain a market for
the Units of the Trusts at prices based upon the aggregate bid price of the
underlying bonds, as more fully described under "Public Offering--Market for
Units" in Part B. If such a market is not maintained, a Unit holder will be
able to dispose of his Units through redemption, at prices that are also based
upon the aggregate bid price of the underlying bonds. Units can be sold at any
time without fee or penalty.
 
MONTHLY DISTRIBUTIONS of principal and interest received by each Trust will be
made on or shortly after the fifteenth day of each month to holders of record
on the first day of that month. For further information regarding the
distributions by each Trust, see "Summary of Essential Information".

      record of Units of such Trust as of a date prior to the computation date,
      on a pro rata share basis. (See Part B, "Redemption of Units--Computation
      of Redemption Price per Unit.")
  *** Per $1,000 principal amount of Bonds, plus expenses. (See Part B, "Rights
      of Unit Holders--Distribution of Interest and Principal.") During the
      first year, the Trustee's fee will be adjusted downward by $.35 and $.20
      per Unit for the National Trust and Maryland Trust, respectively; annual
      income will be $54.09 and $53.68 per Unit, respectively; estimated
      expenses per Unit will be $2.01 and $2.08, respectively; and estimated
      net annual income per Unit will remain the same as shown. The Trustee has
      agreed to the foregoing to cover interest on any Bonds accruing prior to
      their expected dates of delivery since interest will not accrue to the
      benefit of Unit holders until such Bonds are actually delivered to the
      Trust.
 **** Each Trust (and therefore the investors) will bear all or a portion of
      its organizational costs--including costs of preparing the registration
      statement, the trust indenture and other closing documents, registering
      units with the SEC and the states and the initial audit of the Trust--as
      is common for mutual funds. Advertising and selling expenses, as well as
      any organizational costs not paid by a Trust, will be paid by the
      Underwriters at no cost to the Trust.
***** The Estimated Current Return is calculated by dividing the Estimated Net
      Annual Interest Income per Unit by the Public Offering Price per Unit.
      The Estimated Net Annual Interest Income per Unit will vary with changes
      in fees and expenses of the Trustee and the Evaluator and with the
      principal prepayment, redemption, maturity, exchange or sale of Bonds
      while the Public Offering Price will vary with changes in the offering
      price of the underlying Bonds; therefore, there is no assurance that the
      present Estimated Current Return indicated above will be realized in the
      future. The Estimated Long-Term Return is calculated using a formula
      which (1) takes into consideration, and factors in the relative
      weightings of, the market values, yields (which takes into account the
      amortization of premiums and the accretion of discounts) and estimated
      retirements of all of the Bonds in the Trust and (2) takes into account
      the expenses and sales charge associated with each Unit. Since the market
      values and estimated retirements of the Bonds and the expenses of the
      Trust will change, there is no assurance that the present Estimated Long-
      Term Return as indicated above will be realized in the future. The
      Estimated Current Return and Estimated Long-Term Return are expected to
      differ because the calculation of the Estimated Long-Term Return reflects
      the estimated date and amount of principal returned while the Estimated
      Current Return calculations include only Net Annual Interest Income and
      Public Offering Price as of the Date of Deposit.

PORTFOLIO SUMMARY AS OF DATE OF DEPOSIT
 
NATIONAL TRUST 228
 
  The Portfolio of the National Trust contains 21 issues of Bonds of issuers
located in 16 States. All of the issues are payable from the income of
specific projects or authorities and are not supported by the issuer's power
to levy taxes. Although income to pay such Bonds may be derived from more than
one source, the primary sources of such income and the percentage of the Bonds
in this Trust deriving income from such sources are as follows: hospital and
health care facilities: 34.5%*; housing facilities: 32.3%; power facilities:
8.8%; pollution control facilities: 14.2%; water and sewer facilities: 4.2%;
and convention facilities: 6.0%. The Trust is considered to be concentrated in
hospital and health care facilities and housing facilities issues.+ (See Part
B, "Tax Exempt Securities Trust--Risk Factors" for a brief summary of
additional considerations relating to certain of these issues). 28.9% of the
Bonds in this Trust are insured as to timely payment of principal and interest
by certain insurance companies (AMBAC, 6.0%; FGIC, 4.8%; and MBIA, 18.1%) (see
Part B, "Tax Exempt Securities Trust--Risk Factors--Insurance"). Thirteen
Bonds in this Trust have been issued with an "original issue discount." (See
Part B, "Taxes"). The average life to maturity of the Bonds in the National
Trust is 28.2 years.
 
  As of the Date of Deposit, 89.3% of the Bonds in this Trust are rated by
Standard & Poor's (35.3% rated AAA, 23.2% rated AA and 30.8% rated A); and
10.7% are rated by Moody's (4.3% rated Aaa and 6.4% rated A). For a
description of the meaning of the applicable rating symbols as published by
the rating agencies, see Part B, "Bond Ratings." It should be emphasized,
however, that the ratings of the rating agencies represent their opinions as
to the quality of the Bonds which they undertake to rate, and that these
ratings are general and are not absolute standards of quality and may change
from time to time.
 
  12.4% of the Bonds in the National Trust were acquired from the Sponsor as
sole underwriter or from an underwriting syndicate in which the Sponsor
participated, or otherwise from the Sponsor's own organization. (See Part B,
"Public Offering--Sponsor's and Underwriters' Profits.")
 
MARYLAND TRUST 101
 
  The Portfolio of the Maryland Trust contains 6 issues of Bonds of issuers
located in the State of Maryland and the Commonwealth of Puerto Rico. Of the
Bonds in this Trust, one was issued by the Commonwealth of Puerto Rico
(representing 12.1%* of the Bonds in the Trust) and was issued to finance
transportation facilities. The remaining issues are payable from the income of
specific projects or authorities and are not supported by the issuer's power
to levy taxes. Although income to pay such Bonds may be derived from more than
one source, the primary sources of such income and the percentage of the Bonds
in this Trust deriving income from such sources are as follows: hospital and
health care facilities: 29.7%; housing facilities: 18.5%; industrial
development facilities: 24.2%; and educational facilities: 15.5%. The Trust is
considered to be concentrated in hospital and health care facilities issues.+
(See Part B, "Tax Exempt Securities Trust--Risk Factors" for a brief summary
of additional considerations relating to certain of these issues.) 24.2% of
the Bonds in this Trust are insured as to timely payment of principal and
interest by certain insurance companies (MBIA, 24.2%) (see Part B, "Tax Exempt
Securities Trust--Risk Factors--Insurance"). Five Bonds in this Trust have
been issued with an "original issue discount." (See Part B, "Taxes.") The
average life to maturity of the Bonds in the Maryland Trust is 28.1 years.

 Bonds in that category constitute 25% or more of the aggregate offering price
 of the Bonds in the Trust.

                          INDEPENDENT AUDITORS' REPORT
 
To the Sponsor, Trustee and Unit Holders of Tax Exempt Securities Trust,
 National Trust 228 and Maryland Trust 101:
 
  We have audited the accompanying statements of financial condition, including
the portfolios of securities, of each of the respective trusts constituting Tax
Exempt Securities Trust, National Trust 228 and Maryland Trust 101 as of
December 10, 1997. These financial statements are the responsibility of the
Trustee (see note 6 to the statements of financial condition). 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 statements of financial condition are
free of material misstatement. An audit of a statement of financial condition
includes examining, on a test basis, evidence supporting the amounts and
disclosures in that statement of financial condition. Our procedures included
confirmation with the Trustee of an irrevocable letter of credit deposited on
December 10, 1997, for the purchase of securities, as shown in the statements
of financial condition and portfolios of securities. An audit of a statement of
financial condition also includes assessing the accounting principles used and
significant estimates made by the Trustee, as well as evaluating the overall
statement of financial condition presentation. We believe that our audits of
the statements of financial condition provide a reasonable basis for our
opinion.
 
  In our opinion, the statements of financial condition referred to above
present fairly, in all material respects, the financial position of each of the
respective trusts constituting Tax Exempt Securities Trust, National Trust 228
and Maryland Trust 101 as of December 10, 1997, in conformity with generally
accepted accounting principles.

(1) Aggregate cost to each Trust of the Bonds listed under the Portfolios of
    Securities on the immediately following pages is based on offering prices
    as of 1:00 P.M. on December 10, 1997, the Date of Deposit, determined by
    the Evaluator on the basis set forth in Part B, "Public Offering--Offering
    Price." Svenska Handelsbanken issued an irrevocable letter of credit in the
    aggregate principal amount of $11,000,000 which was deposited with the
    Trustee for the purchase of $10,000,000 principal amount of Bonds pursuant
    to contracts to purchase such Bonds at the Sponsor's aggregate cost of
    $9,951,182 plus $114,432 representing accrued interest thereon through the
    Date of Deposit.
(2) The Indenture provides that the Trustee will advance amounts equal to the
    accrued interest on the underlying securities of each Trust (net of accrued
    expenses) through the Date of Deposit and that such amounts will be
    distributed to the Sponsor as Unit holder of record on such date, as set
    forth in Part B, "Rights of Unit Holders--Distribution of Interest and
    Principal."
(3) Organizational costs to be paid by the Trusts have been deferred and will
    be amortized over five years.
(4) Aggregate public offering price (exclusive of interest) computed on 8,000
    and 2,000 Units of National Trust and Maryland Trust, respectively, on the
    basis set forth in Part B, "Public Offering--Offering Price."
(5) Sales charge of 4.70% computed on 8,000 and 2,000 Units of National Trust
    and Maryland Trust, respectively, on the basis set forth in Part B, "Public
    Offering--Offering Price."
(6) The Trustee has custody of and responsibility for all accounting and
    financial books, records, financial statements and related data of each
    Trust and is responsible for establishing and maintaining a system of
    internal controls directly related to, and designed to provide reasonable
    assurance as to the integrity and reliability of, financial reporting of
    each Trust. The Trustee is also responsible for all estimates and accruals
    reflected in each Trust's financial statements. The Evaluator determines
    the price for each underlying Bond included in each Trust's Portfolio of
    Securities on the basis set forth in Part B, "Public Offering--Offering
    Price."

NOTES TO PORTFOLIOS OF SECURITIES
 
(1)For a description of the meaning of the applicable rating symbols as
   published by Standard & Poor's Ratings Group, a division of McGraw-Hill,
   Inc. and Moody's Investors Service(*), see Part B, "Bond Ratings".
 
(2) There is shown under this heading the year in which each issue of Bonds
   initially is redeemable and the redemption price for that year; unless
   otherwise indicated, each issue continues to be redeemable at declining
   prices thereafter, but not below par. "SF" indicates a sinking fund has been
   or will be established with respect to an issue of Bonds. The prices at
   which Bonds may be redeemed or called prior to maturity may or may not
   include a premium and, in certain cases, may be less than the cost of the
   Bonds to a Trust. Certain Bonds in a Portfolio, including Bonds listed as
   not being subject to redemption provisions, may be redeemed in whole or in
   part other than by operation of the stated redemption or sinking fund
   provision under certain unusual or extraordinary circumstances specified in
   the instruments setting forth the terms and provisions of such Bonds. For
   example, see discussion of obligations of housing authorities in Part B,
   "Tax Exempt Securities Trust--Portfolio."
 
(3) Contracts to purchase Bonds were entered into during the period September
   9, 1997, through December 10, 1997, with the settlement date on December 16,
   1997, except for three delayed settlement Bonds in the National Trust and
   one delayed settlement Bond in the Maryland Trust with final settlement
   dates through January 8, 1998. The Profit to the Sponsor on Deposit totals
   $65,099 and $10,880 for the National Trust and Maryland Trust, respectively.
 
(4) Evaluation of the Bonds by the Evaluator is made on the basis of current
   offering prices for the Bonds. The current offering prices of the Bonds are
   greater than the current bid prices of the Bonds. The Redemption Price per
   Unit and the public offering price of the Units in the secondary market are
   determined on the basis of the current bid prices of the Bonds. (See Part B,
   "Public Offering--Offering Price" and "Rights of Unit Holders--Redemption of
   Units.") Yield of Bonds was computed on the basis of offering prices on the
   date of deposit. The aggregate bid price of the Bonds in the National Trust
   and Maryland Trust on December 10, 1997, was $7,917,739 and $1,995,948,
   respectively.

TAX EXEMPT SECURITIES TRUST
 
THE TRUSTS
 
  For over 20 years, Tax Exempt Securities Trust has specialized in quality
municipal bond investments designed to meet a variety of investment objectives
and tax situations. Tax Exempt Securities Trust is a convenient and cost
effective alternative to individual bond purchases. Each Trust is one of a
series of similar but separate unit investment trusts created under the laws of
the State of New York by a Trust Indenture and Agreement and related Reference
Trust Agreement dated the Date of Deposit (collectively, the "Trust
Agreement"), of Smith Barney Inc., as Sponsor, The Chase Manhattan Bank, as
Trustee, and Kenny S&P Evaluation Services, a business unit of J.J. Kenny
Company, Inc., as Evaluator. Each Trust containing Bonds of a State for which
such Trust is named (a "State Trust") and each National Trust, Selected Term
Trust, Long-Intermediate Term Trust, Intermediate Term Trust, Short-
Intermediate Term Trust and Short Term Trust are referred to herein as the
"Trust" or "Trusts," unless the context requires otherwise. On the Date of
Deposit, the Sponsor deposited contracts and funds (represented by a certified
check or checks and/or an irrevocable letter or letters of credit, issued by a
major commercial bank) for the purchase of certain interest-bearing obligations
(the "Bonds") and/or Units of preceding Series of Tax Exempt Securities Trust
(such Bonds and Units of preceding Series of Tax Exempt Securities Trust, if
any, (the "Deposited Units") being referred to herein collectively as the
"Securities"). The Trustee thereafter delivered to the Sponsor registered
certificates of beneficial interest (the "Certificates") representing the units
(the "Units") comprising the entire ownership of each Trust, which Units are
being offered hereby. References to multiple Trusts in Part B herein should be
read as references to a single Trust if Part A indicates the creation of only
one Trust.
 
  Notwithstanding the availability of the above-mentioned certified check or
checks and/or irrevocable letter or letters of credit, it is expected that the
Sponsor will pay for the Bonds as the contracts for their purchase become due.
A substantial portion of such contracts have not become due by the date of this
Prospectus. To the extent Units are sold prior to the settlement of such
contracts, the Sponsor will receive the purchase price on such Units prior to
the time at which they pay for Bonds pursuant to such contracts and have the
use of such funds during this period.
 
OBJECTIVES
 
  A tax-exempt unit investment trust provides many of the same benefits as
individual bond purchases, while the Unit holder avoids the complexity of
analyzing, selecting and monitoring a multi-bond portfolio. The objectives of a
Trust are tax-exempt income and conservation of capital through an investment
in a diversified portfolio of municipal bonds. There is, of course, no
guarantee that a Trust's objectives will be achieved since the payment of
interest and the preservation of principal are dependent upon the continued
ability of the issuers of the bonds to meet such obligations. Subsequent to the
Date of Deposit, the ratings of the Bonds set forth in Part A--"Portfolio of
Securities" may decline due to, among other factors, a decline in
creditworthiness of the issuer of said Bonds.
 
PORTFOLIO
 
  The Sponsor's investment professionals select Bonds for the Trust portfolios
from among the 200,000 municipal bond issues that vary according to bond
purpose, credit quality and years to maturity. The following factors, among
others, were considered in selecting the Bonds for each Trust: (1) the Bonds
are obligations of the states, counties, territories or municipalities of the
United States and authorities or political subdivisions thereof, so that the
interest on them will, in the opinion of recognized bond counsel to the issuing
governmental authorities, be exempt from Federal tax (including alternative
minimum tax) under existing law to the extent described in "Taxes", (2) all the
Bonds deposited in a State Trust are obligations of the State for which such
Trust is named or of the counties, territories or municipalities of such State,
and authorities or political subdivisions thereof, or of the Territory of Guam
or the Commonwealth of Puerto Rico, so that the interest on them will, in the
opinion of recognized bond counsel to the issuing governmental authorities, be
exempt from regular Federal income tax (including alternative minimum tax)
under existing law to the extent described in "Taxes" and from state income
taxes in the state for which such State Trust is named to the extent described
in Part C, (3) the Bonds are rated A or better by a major bond rating agency,
(4) the Bonds were chosen, in part, on the basis of their respective maturity
dates and offer a degree of call protection, (5) the Bonds are diversified as
to purpose of issue and location of issuer, except in the case of a State Trust
where the Bonds are diversified only as to purpose of issue, and (6) in the
opinion of the Sponsor, the Bonds are fairly valued relative to other bonds of
comparable quality and maturity.
 
  The Bonds in the Portfolio of a Trust were chosen in part on the basis of
their respective maturity dates. The Bonds in each Trust will have a dollar-
weighted average portfolio maturity as designated in Part A--"Portfolio Summary
as of Date of Deposit." For the
 
                                      B-1
<PAGE>
 
actual maturity date of each of the Bonds contained in a Trust, which date may
be earlier or later than the dollar-weighted average portfolio maturity of the
Trust, see Part A, "Portfolio of Securities" for information relating to the
particular Trust. A sale or other disposition of a Bond by the Trust prior to
the maturity of such Bond may be at a price which results in a loss to the
Trust. The inability of an issuer to pay the principal amount due upon the
maturity of a Bond would result in a loss to the Trust.
 
  In the event that any contract for the purchase of any Bond fails, the
Sponsor is authorized under the Trust Agreement, subject to the conditions set
forth below, to instruct the Trustee to acquire other securities (the
"Replacement Bonds") for inclusion in the Portfolio of the affected Trust. Any
Replacement Bonds must be deposited not later than the earlier of (i) the first
monthly Distribution Date of the Trust and (ii) 90 days after such Trust was
established. The cost and aggregate principal amount of a Replacement Bond may
not exceed the cost and aggregate principal amount of the Bond which it
replaces. In addition, a Replacement Bond must (1) be a tax-exempt bond; (2)
have a fixed maturity or disposition date comparable to the Bond it replaces;
(3) be purchased at a price that results in a yield to maturity and in a
current return, in each case as of the execution and delivery of the Trust
Agreement, which is approximately equivalent to the yield to maturity and
current return of the Bond which it replaces; (4) be purchased within twenty
days after delivery of notice of the failed contracts; and (5) be rated in a
category A or better by Standard & Poor's, Moody's, Fitch, or Duff & Phelps.
Whenever a Replacement Bond has been acquired for a Trust, the Trustee shall,
within five days thereafter, notify all Unit holders of such Trust of the
acquisition of the Replacement Bond.
 
  In the event that a contract to purchase any of the Bonds fails and
Replacement Bonds are not acquired, the Trustee will, not later than the second
monthly Distribution Date, distribute to Unit holders the funds attributable to
the failed contract. The Sponsor will, in such a case, refund the sales charge
applicable to the failed contract. If less than all the funds attributable to a
failed contract are applied to purchase Replacement Bonds, the remaining moneys
will be distributed to Unit holders not later than the second monthly
Distribution Date. Moreover, the failed contract will reduce the Estimated Net
Annual Income per Unit, and may lower the Estimated Current Return and
Estimated Long-Term Return indicated in the "Summary of Essential Information"
in Part A.
 
RISK FACTORS
 
  Certain Bonds in a Trust may have been purchased by the Sponsor on a "when,
as and if issued" basis; that is, they had not yet been issued by their
governmental entity on the Date of Deposit (although such governmental entity
had committed to issue such Bonds). Contracts relating to such "when, as and if
issued" Bonds are not expected to be settled by the first settlement date for
Units. In the case of these and/or certain other Bonds, the delivery of the
Bonds may be delayed ("delayed delivery") or may not occur. Unit holders who
purchased their Units of a Trust prior to the date such Bonds are actually
delivered to the Trustee may have to make a downward adjustment in the tax
basis of their Units for interest accruing on such "when, as and if issued" or
"delayed delivery" Bonds during the interval between their purchase of Units
and delivery of such Bonds, since the Trust and the Unit holders will not be
reimbursing the Sponsor for interest accruing on such "when, as and if issued"
or "delayed delivery" Bonds during the period between the settlement date for
the Units and the delivery of such Bonds into the Trust. (See "Taxes.") Such
adjustment has been taken into account in computing the Estimated Current
Return and Estimated Long-Term Return set forth herein, which is slightly lower
than Unit holders may receive after the first year. (See Part A, "Summary of
Essential Information.") To the extent that the delivery of such Bonds is
delayed beyond their respective expected delivery dates, the Estimated Current
Return and Estimated Long-Term Return for the first year may be lower than
indicated in the "Summary of Essential Information" in Part A.
 
  Most of the Bonds in the Portfolio of a Trust are subject to redemption prior
to their stated maturity date pursuant to sinking fund or call provisions. (See
Part A--"Portfolio Summary as of Date of Deposit" for information relating to
the particular Trust described therein.) In general, a call or redemption
provision is more likely to be exercised when the offering price valuation of a
bond is higher than its call or redemption price, as it might be in periods of
declining interest rates, than when such price valuation is less than the
bond's call or redemption price. To the extent that a Bond was deposited in a
Trust at a price higher than the price at which it is redeemable, redemption
will result in a loss of capital when compared with the original public
offering price of the Units. Conversely, to the extent that a Bond was acquired
at a price lower than the redemption price, redemption will result in an
increase in capital when compared with the original public offering price of
the Units. Monthly distributions will generally be reduced by the amount of the
income which would otherwise have been paid with respect to redeemed bonds. The
Estimated Current Return and Estimated Long-Term Return of the Units may be
affected by such redemptions. Each Portfolio of Securities in Part A contains a
listing of the sinking fund and call provisions, if any, with respect to each
of the Bonds in a Trust. 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 a Trust will
retain for any length of time its present size and composition. NEITHER THE
SPONSOR NOR THE TRUSTEE SHALL BE LIABLE IN ANY WAY FOR ANY DEFAULT, FAILURE OR
DEFECT IN ANY BOND.
 
  The Portfolio of the Trust may consist of some Bonds whose current market
values were below face value on the Date of Deposit. A primary reason for the
market value of such Bonds being less than face value at maturity is that the
interest coupons of such Bonds are at lower rates than the current market
interest rate for comparably rated Bonds, even though at the time of the
issuance of such Bonds
 
                                      B-2
<PAGE>
 
the interest coupons thereon represented then prevailing interest rates on
comparably rated Bonds then newly issued. Bonds selling at market discounts
tend to increase in market value as they approach maturity when the principal
amount is payable. A market discount tax-exempt Bond held to maturity will have
a larger portion of its total return in the form of taxable ordinary income and
less in the form of tax-exempt income than a comparable Bond bearing interest
at current market rates. Under the provisions of the Internal Revenue Code in
effect on the date of this Prospectus, any income attributable to market
discount will be taxable but will not be realized until maturity, redemption or
sale of the Bonds or Units.
 
  As set forth under "Portfolio Summary as of Date of Deposit", the Trust may
contain or be concentrated in one or more of the classifications of Bonds
referred to below. A Trust is considered to be "concentrated" in a particular
category when the Bonds in that category constitute 25% or more of the
aggregate value of the Portfolio. (See Part A--"Portfolio Summary as of Date of
Deposit" for information relating to the particular Trust described therein.)
An investment in Units of the Trust should be made with an understanding of the
risks that these investments may entail, certain of which are described below.
 
  GENERAL OBLIGATION BONDS. Certain of the Bonds in the Portfolio may be
general obligations of a governmental entity that are secured by the taxing
power of the entity. General obligation bonds are backed by the issuer's pledge
of its full faith, credit and taxing power for the payment of principal and
interest. However, the taxing power of any governmental entity may be limited
by provisions of state constitutions or laws and an entity's credit will depend
on many factors, including an 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 and the extent to which the entity relies on
Federal or state aid, access to capital markets or other factors beyond the
entity's control. Many issuers are facing highly difficult choices about
significant tax increases and/or spending reductions in order to restore
budgetary balance. Failure to implement these actions on a timely basis could
force the issuers to depend upon market access to finance deficits or cash flow
needs.
 
  In addition, certain of the Bonds in the Trust may be obligations of issuers
(including California issuers) who rely in whole or in part on ad valorem real
property taxes as a source of revenue. Certain proposals, in the form of state
legislative proposals or voter initiatives, to limit ad valorem real property
taxes have been introduced in various states, and an amendment to the
constitution of the State of California, providing for strict limitations on ad
valorem real property taxes, has had a significant impact on the taxing powers
of local governments and on the financial conditions of school districts and
local governments in California. It is not possible at this time to predict the
final impact of such measures, or of similar future legislative or
constitutional measures, on school districts and local governments or on their
abilities to make future payments on their outstanding debt obligations.
 
  INDUSTRIAL DEVELOPMENT REVENUE BONDS ("IDRS"). IDRs, including pollution
control revenue bonds, are tax-exempt securities issued by states,
municipalities, public authorities or similar entities ("issuers") to finance
the cost of acquiring, constructing or improving various projects, including
pollution control facilities and certain industrial development facilities.
These projects are usually operated by corporate entities. IDRs are not general
obligations of governmental entities backed by their taxing power. Issuers are
only obligated to pay amounts due on the IDRs to the extent that funds are
available from the unexpended proceeds of the IDRs or receipts or revenues of
the issuer under arrangements between the issuer and the corporate operator of
a project. These arrangements may be in the form of a lease, installment sale
agreement, conditional sale agreement or loan agreement, but in each case the
payments to the issuer are designed to be sufficient to meet the payments of
amounts due on the IDRs.
 
  IDRs are generally issued under bond resolutions, agreements or trust
indentures pursuant to which the revenues and receipts payable under the
issuer's arrangements with the corporate operator of a particular project have
been assigned and pledged to the holders of the IDRs or a trustee for the
benefit of the holders of the IDRs. In certain cases, a mortgage on the
underlying project has been assigned to the holders of the IDRs or a trustee as
additional security for the IDRs. In addition, IDRs are frequently directly
guaranteed by the corporate operator of the project or by another affiliated
company. Regardless of the structure, payment of IDRs is solely dependent upon
the creditworthiness of the corporate operator of the project or corporate
guarantor. Corporate operators or guarantors that are industrial companies may
be affected by many factors which may have an adverse impact on the credit
quality of the particular company or industry. These include cyclicality of
revenues and earnings, regulatory and environmental restrictions, litigation
resulting from accidents or environmentally-caused illnesses, extensive
competition (including that of low-cost foreign companies), unfunded pension
fund liabilities or off-balance sheet items, and financial deterioration
resulting from leveraged buy-outs or takeovers. However, certain of the IDRs in
the Portfolio may be additionally insured or secured by letters of credit
issued by banks or otherwise guaranteed or secured to cover amounts due on the
IDRs in the event of default in payment by an issuer.
 
  HOSPITAL AND HEALTH CARE FACILITY BONDS. The ability of hospitals and other
health care facilities to meet their obligations with respect to revenue bonds
issued on their behalf is dependent on various factors, including but not
limited to the level of payments received from private third-party payors and
government programs and the cost of providing health care services.
 
                                      B-3
<PAGE>
 
  A significant portion of the revenues of hospitals and other health care
facilities is derived from private third-party payors and government programs,
including the Medicare and Medicaid programs. Both private third-party payors
and government programs have undertaken cost containment measures designed to
limit payments made to health care facilities. Furthermore, government programs
are subject to statutory and regulatory changes, retroactive rate adjustments,
administrative rulings and government funding restrictions, all of which may
materially decrease the rate of program payments for health care facilities.
Certain special revenue obligations (i.e., Medicare or Medicaid revenues) may
be payable subject to appropriations by state legislatures. There can be no
assurance that payments under governmental programs will remain at levels
comparable to present levels or will, in the future, be sufficient to cover the
costs allocable to patients participating in such programs. In addition, there
can be no assurance that a particular hospital or other health care facility
will continue to meet the requirements for participation in such programs.
 
  The costs of providing health care services are subject to increase as a
result of, among other factors, changes in medical technology and increased
labor costs. In addition, health care facility construction and operation is
subject to federal, state and local regulation relating to the adequacy of
medical care, equipment, personnel, operating policies and procedures, rate-
setting, and compliance with building codes and environmental laws. Facilities
are subject to periodic inspection by governmental and other authorities to
assure continued compliance with the various standards necessary for licensing
and accreditation. These regulatory requirements are subject to change and, to
comply, it may be necessary for a hospital or other health care facility to
incur substantial capital expenditures or increased operating expenses to
effect changes in its facilities, equipment, personnel and services.
 
  Hospitals and other health care facilities are subject to claims and legal
actions by patients and others in the ordinary course of business. Although
these claims are generally covered by insurance, there can be no assurance that
a claim will not exceed the insurance coverage of a health care facility or
that insurance coverage will be available to a facility. In addition, a
substantial increase in the cost of insurance could adversely affect the
results of operations of a hospital or other health care facility. The Clinton
Administration may impose regulations which could limit price increases for
hospitals or the level of reimbursements for third-party payors or other
measures to reduce health care costs and make health care available to more
individuals, which would reduce profits for hospitals. Some states, such as New
Jersey, have significantly changed their reimbursement systems. If a hospital
cannot adjust to the new system by reducing expenses or raising rates,
financial difficulties may arise. Also, Blue Cross has denied reimbursement for
some hospitals for services other than emergency room services. The lost volume
would reduce revenues unless replacement patients were found.
 
  Certain hospital bonds may provide for redemption at par at any time upon the
sale by the issuer of the hospital facilities to a non-affiliated entity, if
the hospital becomes subject to ad valorem taxation, or in various other
circumstances. For example, certain hospitals may have the right to call bonds
at par if the hospital may be legally required because of the bonds to perform
procedures against specified religious principles or to disclose information
that is considered confidential or privileged. Certain FHA-insured bonds may
provide that all or a portion of these bonds, otherwise callable at a premium,
can be called at par in certain circumstances. If a hospital defaults upon a
bond obligation, the realization of Medicare and Medicaid receivables may be
uncertain and, if the bond obligation is secured by the hospital facilities,
legal restrictions on the ability to foreclose upon the facilities and the
limited alternative uses to which a hospital can be put may severely reduce its
collateral value.
 
  The Internal Revenue Service has engaged in a program of audits of certain
large tax-exempt hospital and health care facility organizations. Although
these audits have not yet been completed, it has been reported that the tax-
exempt status of some of these organizations may be revoked. At this time, it
is uncertain whether any of the hospital and health care facility bonds held by
the Trust will be affected by such audit proceedings.
 
  SINGLE FAMILY AND MULTI-FAMILY HOUSING BONDS. Multi-family housing revenue
bonds and single family mortgage revenue bonds are state and local housing
issues that have been issued to provide financing for various housing projects.
Multi-family housing revenue bonds are payable primarily from the revenues
derived from mortgage loans to housing projects for low to moderate income
families. Single-family mortgage revenue bonds are issued for the purpose of
acquiring from originating financial institutions notes secured by mortgages on
residences.
 
  Housing obligations are not general obligations of the issuer although
certain obligations may be supported to some degree by Federal, state or local
housing subsidy programs. Budgetary constraints experienced by these programs
as well as the failure by a state or local housing issuer to satisfy the
qualifications required for coverage under these programs or any legal or
administrative determinations that the coverage of these programs is not
available to a housing issuer, probably will result in a decrease or
elimination of subsidies available for payment of amounts due on the issuer's
obligations. The ability of housing issuers to make debt service payments on
their obligations may also be affected by various economic and non-economic
developments including, among other things, the achievement and maintenance of
sufficient occupancy levels and adequate rental income in multi-family
projects, the rate of default on mortgage loans underlying single family issues
and the ability of mortgage insurers to pay claims, employment and income
conditions prevailing in local markets, increases in construction costs, taxes,
utility costs and other operating expenses, the managerial ability of project
managers, changes in laws and governmental regulations and economic trends
generally in the localities in which the projects are situated. Occupancy of
multi-family housing projects may also be adversely affected by high rent
levels and income limitations imposed under Federal, state or local programs.
 
                                      B-4
<PAGE>
 
  All single family mortgage revenue bonds and certain multi-family housing
revenue bonds are prepayable over the life of the underlying mortgage or
mortgage pool, and therefore the average life of housing obligations cannot be
determined. However, the average life of these obligations will ordinarily be
less than their stated maturities. Single-family issues are subject to
mandatory redemption in whole or in part from prepayments on underlying
mortgage loans; mortgage loans are frequently partially or completely prepaid
prior to their final stated maturities as a result of events such as declining
interest rates, sale of the mortgaged premises, default, condemnation or
casualty loss. Multi-family issues are characterized by mandatory redemption at
par upon the occurrence of monetary defaults or breaches of covenants by the
project operator. Additionally, housing obligations are generally subject to
mandatory partial redemption at par to the extent that proceeds from the sale
of the obligations are not allocated within a stated period (which may be
within a year of the date of issue). To the extent that these obligations were
valued at a premium when a Holder purchased Units, any prepayment at par would
result in a loss of capital to the Holder and, in any event, reduce the amount
of income that would otherwise have been paid to Holders.
 
  The tax exemption for certain housing revenue bonds depends on qualification
under Section 143 of the Internal Revenue Code of 1986, as amended (the
"Code"), in the case of single family mortgage revenue bonds or Section
142(a)(7) of the Code or other provisions of Federal law in the case of certain
multi-family housing revenue bonds (including Section 8 assisted bonds). These
sections of the Code or other provisions of Federal law contain certain ongoing
requirements, including requirements relating to the cost and location of the
residences financed with the proceeds of the single family mortgage revenue
bonds and the income levels of tenants of the rental projects financed with the
proceeds of the multi-family housing revenue bonds. While the issuers of the
bonds and other parties, including the originators and servicers of the single-
family mortgages and the owners of the rental projects financed with the multi-
family housing revenue bonds, generally covenant to meet these ongoing
requirements and generally agree to institute procedures designed to ensure
that these requirements are met, there can be no assurance that these ongoing
requirements will be consistently met. The failure to meet these requirements
could cause the interest on the bonds to become taxable, possibly retroactively
to the date of issuance, thereby reducing the value of the bonds, subjecting
the Holders to unanticipated tax liabilities and possibly requiring the Trustee
to sell the bonds at reduced values. Furthermore, any failure to meet these
ongoing requirements might not constitute an event of default under the
applicable mortgage or permit the holder to accelerate payment of the bond or
require the issuer to redeem the bond. In any event, where the mortgage is
insured by the Federal Housing Administration, its consent may be required
before insurance proceeds would become payable to redeem the mortgage bonds.
 
  POWER FACILITY BONDS. The ability of utilities to meet their obligations with
respect to revenue bonds issued on their behalf is dependent on various
factors, including the rates they may charge their customers, the demand for a
utility's services and the cost of providing those services. Utilities, in
particular investor-owned utilities, are subject to extensive regulations
relating to the rates which they may charge customers. Utilities can experience
regulatory, political and consumer resistance to rate increases. Utilities
engaged in long-term capital projects are especially sensitive to regulatory
lags in granting rate increases. Any difficulty in obtaining timely and
adequate rate increases could adversely affect a utility's results of
operations.
 
  The demand for a utility's services is influenced by, among other factors,
competition, weather conditions and economic conditions. Electric utilities,
for example, have experienced increased competition as a result of the
availability of other energy sources, the effects of conservation on the use of
electricity, self-generation by industrial customers and the generation of
electricity by co-generators and other independent power producers. Also,
increased competition will result if federal regulators determine that
utilities must open their transmission lines to competitors. Utilities which
distribute natural gas also are subject to competition from alternative fuels,
including fuel oil, propane and coal.
 
  The utility industry is an increasing cost business making the cost of
generating electricity more expensive and heightening its sensitivity to
regulation. A utility's costs are influenced by the utility's cost of capital,
the availability and cost of fuel and other factors. In addition, natural gas
pipeline and distribution companies have incurred increased costs as a result
of long-term natural gas purchase contracts containing "take or pay" provisions
which require that they pay for natural gas even if natural gas is not taken by
them. There can be no assurance that a utility will be able to pass on these
increased costs to customers through increased rates. Utilities incur
substantial capital expenditures for plant and equipment. In the future they
will also incur increasing capital and operating expenses to comply with
environmental legislation such as the Clean Air Act of 1990, and other energy,
licensing and other laws and regulations relating to, among other things, air
emissions, the quality of drinking water, waste water discharge, solid and
hazardous substance handling and disposal, and siting and licensing of
facilities. Environmental legislation and regulations are changing rapidly and
are the subject of current public policy debate and legislative proposals. It
is increasingly likely that some or many utilities will be subject to more
stringent environmental standards in the future that could result in
significant capital expenditures. Future legislation and regulation could
include, among other things, regulation of so-called electromagnetic fields
associated with electric transmission and distribution lines as well as
emissions of carbon dioxide and other so-called greenhouse gases associated
with the burning of fossil fuels. Compliance with these requirements may limit
a utility's operations or require substantial investments in new equipment and,
as a result, may adversely affect a utility's results of operations.
 
                                      B-5
<PAGE>
 
  The electric utility industry in general is subject to various external
factors including (a) the effects of inflation upon the costs of operation and
construction, (b) substantially increased capital outlays and longer
construction periods for larger and more complex new generating units, (c)
uncertainties in predicting future load requirements, (d) increased financing
requirements coupled with limited availability of capital, (e) exposure to
cancellation and penalty charges on new generating units under construction,
(f) problems of cost and availability of fuel, (g) compliance with rapidly
changing and complex environmental, safety and licensing requirements, (h)
litigation and proposed legislation designed to delay or prevent construction
of generating and other facilities, (i) the uncertain effects of conservation
on the use of electric energy, (j) uncertainties associated with the
development of a national energy policy, (k) regulatory, political and consumer
resistance to rate increases and (l) increased competition as a result of the
availability of other energy sources. These factors may delay the construction
and increase the cost of new facilities, limit the use of, or necessitate
costly modifications to, existing facilities, impair the access of electric
utilities to credit markets, or substantially increase the cost of credit for
electric generating facilities. The Sponsor cannot predict at this time the
ultimate effect of such factors on the ability of any issuers to meet their
obligations with respect to Bonds.
 
  The National Energy Policy Act ("NEPA"), which became law in October, 1992,
made it mandatory for a utility to permit non-utility generators of electricity
access to its transmission system for wholesale customers, thereby increasing
competition for electric utilities. NEPA also mandated demand-side management
policies to be considered by utilities. NEPA prohibits the Federal Energy
Regulatory Commission from mandating electric utilities to engage in retail
wheeling, which is competition among suppliers of electric generation to
provide electricity to retail customers (particularly industrial retail
customers) of a utility. However, under NEPA, a state can mandate retail
wheeling under certain conditions.
 
  There is concern by the public, the scientific community, and the U.S.
Congress regarding environmental damage resulting from the use of fossil fuels.
Congressional support for the increased regulation of air, water, and soil
contaminants is building and there are a number of pending or recently enacted
legislative proposals which may affect the electric utility industry. In
particular, on November 15, 1990, legislation was signed into law which
substantially revised the Clean Air Act (the "1990 Amendments"). The 1990
Amendments sought to improve the ambient air quality throughout the United
States by the year 2000. A main feature of the 1990 Amendments is the reduction
of sulphur dioxide and nitrogen oxide emissions caused by electric utility
power plants, particularly those fueled by coal. Under the 1990 Amendments the
U.S. Environmental Protection Agency ("EPA") was required to develop limits for
nitrogen oxide emissions by 1993. The sulphur dioxide reduction will be
achieved in two phases. Phase I addressed specific generating units named in
the 1990 Amendments. In Phase II the total U.S. emissions will be capped at 8.9
million tons by the year 2000. The 1990 Amendments contain provisions for
allocating allowances to power plants based on historical or calculated levels.
An allowance is defined as the authorization to emit one ton of sulphur
dioxide.
 
  The 1990 Amendments also provided for possible further regulation of toxic
air emissions from electric generating units pending the results of several
federal government studies to be conducted over a three to four year period
with respect to anticipated hazards to public health, available corrective
technologies, and mercury toxicity.
 
  Electric utilities which own or operate nuclear power plants are exposed to
risks inherent in the nuclear industry. These risks include exposure to new
requirements resulting from extensive federal and state regulatory oversight,
public controversy, decommissioning costs, and spent fuel and radioactive waste
disposal issues. While nuclear power construction risks are no longer of
paramount concern, the emerging issue is radioactive waste disposal. In
addition, nuclear plants typically require substantial capital additions and
modifications throughout their operating lives to meet safety, environmental,
operational and regulatory requirements and to replace and upgrade various
plant systems. The high degree of regulatory monitoring and controls imposed on
nuclear plants could cause a plant to be out of service or on limited service
for long periods. When a nuclear facility owned by an investor-owned utility or
a state or local municipality is out of service or operating on a limited
service basis, the utility operator or its owners may be liable for the
recovery of replacement power costs. Risks of substantial liability also arise
from the operation of nuclear facilities and from the use, handling, and
possible radioactive emissions associated with nuclear fuel. Insurance may not
cover all types or amounts of loss which may be experienced in connection with
the ownership and operation of a nuclear plant and severe financial
consequences could result from a significant accident or occurrence. The
Nuclear Regulatory Commission has promulgated regulations mandating the
establishment of funded reserves to assure financial capability for the
eventual decommissioning of licensed nuclear facilities. These funds are to be
accrued from revenues in amounts currently estimated to be sufficient to pay
for decommissioning costs.
 
  The ability of state and local joint action power agencies to make payments
on bonds they have issued is dependent in large part on payments made to them
pursuant to power supply or similar agreements. Courts in Washington, Oregon
and Idaho have held that certain agreements between the Washington Public Power
Supply System ("WPPSS") and the WPPSS participants are unenforceable because
the participants did not have the authority to enter into the agreements. While
these decisions are not specifically applicable to agreements entered into by
public entities in other states, they may cause a reexamination of the legal
structure and economic viability of certain projects financed by joint power
agencies, which might exacerbate some of the problems referred to above and
possibly lead to legal proceedings questioning the enforceability of agreements
upon which payment of these bonds may depend.
 
                                      B-6
<PAGE>
 
  WATER AND SEWER REVENUE BONDS. Water and sewer bonds are generally payable
from user fees. The ability of state and local water and sewer authorities to
meet their obligations may be affected by failure of municipalities to utilize
fully the facilities constructed by these authorities, economic or population
decline and resulting decline in revenue from user charges, rising construction
and maintenance costs and delays in construction of facilities, impact of
environmental requirements, failure or inability to raise user charges in
response to increased costs, the difficulty of obtaining or discovering new
supplies of fresh water, the effect of conservation programs and the impact of
"no growth" zoning ordinances. In some cases this ability may be affected by
the continued availability of Federal and state financial assistance and of
municipal bond insurance for future bond issues.
 
  UNIVERSITY AND COLLEGE BONDS. The ability of universities and colleges to
meet their obligations is dependent upon various factors, including the size
and diversity of their sources of revenues, enrollment, reputation, management
expertise, the availability and restrictions on the use of endowments and other
funds, the quality and maintenance costs of campus facilities, and, in the case
of public institutions, the financial condition of the relevant state or other
governmental entity and its policies with respect to education. The
institution's ability to maintain enrollment levels will depend on such factors
as tuition costs, demographic trends, geographic location, geographic diversity
and quality of the student body, quality of the faculty and the diversity of
program offerings.
 
  Legislative or regulatory action in the future at the Federal, state or local
level may directly or indirectly affect eligibility standards or reduce or
eliminate the availability of funds for certain types of student loans or grant
programs, including student aid, research grants and work-study programs, and
may affect indirect assistance for education.
 
  LEASE RENTAL BONDS. Lease rental bonds are issued for the most part by
governmental authorities that have no taxing power or other means of directly
raising revenues. Rather, the authorities are financing vehicles created solely
for the construction of buildings (administrative offices, convention centers
and prisons, for example) or the purchase of equipment (police cars and
computer systems, for example) that will be used by a state or local government
(the "lessee"). Thus, the bonds are subject to the ability and willingness of
the lessee government to meet its lease rental payments which include debt
service on the bonds. Willingness to pay may be subject to changes in the views
of citizens and government officials as to the essential nature of the finance
project. Lease rental bonds are subject, in almost all cases, to the annual
appropriation risk, i.e., the lessee government is not legally obligated to
budget and appropriate for the rental payments beyond the current fiscal year.
These bonds are also subject to the risk of abatement in many states--rental
bonds cease in the event that damage, destruction or condemnation of the
project prevents its use by the lessee. (In these cases, insurance provisions
and reserve funds designed to alleviate this risk become important credit
factors). In the event of default by the lessee government, there may be
significant legal and/or practical difficulties involved in the reletting or
sale of the project. Some of these issues, particularly those for equipment
purchase, contain the so-called "substitution safeguard", which bars the lessee
government, in the event it defaults on its rental payments, from the purchase
or use of similar equipment for a certain period of time. This safeguard is
designed to insure that the lessee government will appropriate the necessary
funds even though it is not legally obligated to do so, but its legality
remains untested in most, if not all, states.
 
  CAPITAL IMPROVEMENT FACILITY BONDS. The Portfolio of a Trust may contain
Bonds which are in the capital improvement facilities category. Capital
improvement bonds are bonds issued to provide funds to assist political
subdivisions or agencies of a state through acquisition of the underlying debt
of a state or local political subdivision or agency which bonds are secured by
the proceeds of the sale of the bonds, proceeds from investments and the
indebtedness of a local political subdivision or agency. The risks of an
investment in such bonds include the risk of possible prepayment or failure of
payment of proceeds on and default of the underlying debt.
 
  SOLID WASTE DISPOSAL BONDS. Bonds issued for solid waste disposal facilities
are generally payable from tipping fees and from revenues that may be earned by
the facility on the sale of electrical energy generated in the combustion of
waste products. The ability of solid waste disposal facilities to meet their
obligations depends upon the continued use of the facility, the successful and
efficient operation of the facility and, in the case of waste-to-energy
facilities, the continued ability of the facility to generate electricity on a
commercial basis. All of these factors may be affected by a failure of
municipalities to fully utilize the facilities, an insufficient supply of waste
for disposal due to economic or population decline, rising construction and
maintenance costs, any delays in construction of facilities, lower-cost
alternative modes of waste processing and changes in environmental regulations.
Because of the relatively short history of this type of financing, there may be
technological risks involved in the satisfactory construction or operation of
the projects exceeding those associated with most municipal enterprise
projects. Increasing environmental regulation on the federal, state and local
level has a significant impact on waste disposal facilities. While regulation
requires more waste producers to use waste disposal facilities, it also imposes
significant costs on the facilities. These costs include compliance with
frequently changing and complex regulatory requirements, the cost of obtaining
construction and operating permits, the cost of conforming to prescribed and
changing equipment standards and required methods of operation and, for
incinerators or waste-to-energy facilities, the cost of disposing of the waste
residue that remains after the disposal process in an environmentally safe
manner. In addition, waste disposal facilities frequently face substantial
opposition by environmental groups and officials to their location and
operation, to the possible adverse effects upon the public health and the
environment that may be caused by wastes disposed of at the facilities and to
alleged improper operating
 
                                      B-7
<PAGE>
 
procedures. Waste disposal facilities benefit from laws which require waste to
be disposed of in a certain manner but any relaxation of these laws could cause
a decline in demand for the facilities' services. Finally, waste-to-energy
facilities are concerned with many of the same issues facing utilities insofar
as they derive revenues from the sale of energy to local power utilities (see
Power Facility Bonds above).
 
  MORAL OBLIGATION BONDS. The Trust may also include "moral obligation" bonds.
If an issuer of moral obligation bonds is unable to meet its obligations, the
repayment of the bonds becomes a moral commitment but not a legal obligation of
the state or municipality in question. Even though the state may be called on
to restore any deficits in capital reserve funds of the agencies or authorities
which issued the bonds, any restoration generally requires appropriation by the
state legislature and accordingly does not constitute a legally enforceable
obligation or debt of the state. The agencies or authorities generally have no
taxing power.
 
  REFUNDED BONDS. Refunded Bonds are typically 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. These obligations are
generally noncallable prior to maturity or the predetermined redemption date.
In a few isolated instances to date, however, bonds which were thought to be
escrowed to maturity have been called for redemption prior to maturity.
 
  AIRPORT, PORT AND HIGHWAY REVENUE BONDS. Certain facility revenue bonds are
payable from and secured by the revenues from the ownership and operation of
particular facilities, such as airports (including airport terminals and
maintenance facilities), bridges, marine terminals, turnpikes and port
authorities. For example, the major portion of gross airport operating income
is generally derived from fees received from signatory airlines pursuant to use
agreements which consist of annual payments for airport use, occupancy of
certain terminal space, facilities, service fees, concessions and leases.
Airport operating income may therefore be affected by the ability of the
airlines to meet their obligations under the use agreements. The air transport
industry is experiencing significant variations in earnings and traffic, due to
increased competition, excess capacity, increased aviation fuel costs,
deregulation, traffic constraints, the recent recession and other factors. As a
result, several airlines experienced severe financial difficulties. Several
airlines have sought protection from their creditors under Chapter 11 of the
Bankruptcy Code while, other airlines have been liquidated. The Sponsor cannot
predict what effect these industry conditions may have on airport revenues
which are dependent for payment on the financial condition of the airlines and
their usage of the particular airport facility. Furthermore, proposed
Legislation would provide the U.S. Secretary of Transportation with the
temporary authority to freeze airport fees upon the occurrence of disputes
between a particular airport facility and the airlines utilizing that facility.
 
  Similarly, payment on bonds related to other facilities is dependent on
revenues from the projects, such as use fees from ports, tolls on turnpikes and
bridges and rents from buildings. Therefore, payment may be adversely affected
by reduction in revenues due to such factors and increased cost of maintenance
or decreased use of a facility, lower cost of alternative modes of
transportation or scarcity of fuel and reduction or loss of rents.
 
  SPECIAL TAX BONDS. Special tax bonds are payable from and secured by the
revenues derived by a municipality from a particular tax such as a tax on the
rental of a hotel room, on the purchase of food and beverages, on the rental of
automobiles or on the consumption of liquor. Special tax bonds are not secured
by the general tax revenues of the municipality, and they do not represent
general obligations of the municipality. Therefore, payment on special tax
bonds may be adversely affected by a reduction in revenues realized from the
underlying special tax due to a general decline in the local economy or
population or due to a decline in the consumption, use or cost of the goods and
services that are subject to taxation. Also, should spending on the particular
goods or services that are subject to the special tax decline, the municipality
may be under no obligation to increase the rate of the special tax to ensure
that sufficient revenues are raised from the shrinking taxable base.
 
  TAX ALLOCATION BONDS. Tax allocation bonds are typically secured by
incremental tax revenues collected on property within the areas where
redevelopment projects, financed by bond proceeds are located ("project
areas"). Such payments are expected to be made from projected increases in tax
revenues derived from higher assessed values of property resulting from
development in the particular project area and not from an increase in tax
rates. Special risk considerations include: reduction of, or a less than
anticipated increase in, taxable values of property in the project area, caused
either by economic factors beyond the Issuer's control (such as a relocation
out of the project area by one or more major property owners) or by destruction
of property due to natural or other disasters; successful appeals by property
owners of assessed valuations; substantial delinquencies in the payment of
property taxes; or imposition of any constitutional or legislative property tax
rate decrease.
 
  TRANSIT AUTHORITY BONDS. Mass transit is generally not self-supporting from
fare revenues. Therefore, additional financial resources must be made available
to ensure operation of mass transit systems as well as the timely payment of
debt service. Often such financial resources include Federal and state
subsidies, lease rentals paid by funds of the state or local government or a
pledge of a special tax such as a sales tax or a property tax. If fare revenues
or the additional financial resources do not increase appropriately to pay for
rising operating expenses, the ability of the issuer to adequately service the
debt may be adversely affected.

  CONVENTION FACILITY BONDS. The Portfolio of a Trust may contain Bonds of
issuers in the convention facilities category. Bonds in the convention
facilities category include special limited obligation securities issued to
finance convention and sports facilities payable from rental payments and
annual governmental appropriations. The governmental agency is not obligated to
make payments in any year in which the monies have not been appropriated to
make such payments. In addition, these facilities are limited use facilities
that may not be used for purposes other than as convention centers or sports
facilities.
 
  CORRECTIONAL FACILITY BONDS. The Portfolio of a Trust may contain Bonds of
issuers in the correctional facilities category. Bonds in the correctional
facilities category include special limited obligation securities issued to
construct, rehabilitate and purchase correctional facilities payable from
governmental rental payments and/or appropriations.
 
  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 closely integrated with that of the mainland United States.
During fiscal year 1995, approximately 89% of Puerto Rico's exports were to the
United States mainland, which was also the source of 65% of Puerto Rico's
imports. In fiscal 1995, Puerto Rico experienced a $4.6 billion positive
adjusted trade balance. The economy of Puerto Rico is dominated by the
manufacturing and service sectors. The manufacturing sector has experienced a
basic change over the years as a result of increased emphasis on higher wage,
high technology industries such as pharmaceuticals, electronics, computers,
microprocessors, professional and scientific instruments, and certain high
technology machinery and equipment. The service sector, including finance,
insurance and real estate, wholesale and retail trade, and hotel and related
services, also plays a major role in the economy. It ranks second only to
manufacturing in contribution to the gross domestic product and leads all
sectors in providing employment. In recent years, the service sector has
experienced significant growth in response to and paralleling the expansion of
the manufacturing sector. Since fiscal 1985, personal income, both aggregate
and per capita, has increased consistently in each fiscal year. In fiscal 1995,
aggregate personal income was $27.0 billion ($22.5 billion in 1987 prices) and
personal income per capita was $7,296 ($6,074 in 1987 prices). Personal income
includes transfer payments to individuals in Puerto Rico under various social
programs. Total federal payments to Puerto Rico, which include many types in
addition to federal transfer payments, are lower on a per capita basis in
Puerto Rico than in any state. Transfer payments to individuals in fiscal 1995
were $5.9 billion, of which $4.0 billion, or 67.6%, represent entitlement to
individuals who had previously performed services or made contributions under
programs such as Social Security, Veterans Benefits and Medicare. The number of
persons employed in Puerto Rico during fiscal 1996 averaged 1,092,300, an
increase of 3.9% over fiscal 1995. The unemployment rate in Puerto Rico for
fiscal 1996 remained the same. The Puerto Rico Planning Board's most recent
gross product forecast for fiscal 1997, made in February 1996, showed an
increase of 2.7%. The Planning Board's Economic Activity Index, a composite
index for thirteen economic indicators, increased 1.6% for fiscal 1996 compared
to fiscal 1995, and 2.0% for fiscal 1995, compared to fiscal 1994. During the
first three months of fiscal 1997 the Index decreased 0.9% compared to the same
period in fiscal 1996, which period showed an increase of 1.7% over the same
period of fiscal 1995. Growth in the Puerto Rico economy in fiscal 1997 depends
on several factors, including the state of the United States economy and the
relative stability in the price of oil imports, the exchange value of the U.S.
dollar, the level of federal transfers and the cost of borrowing.
 
  INSURANCE. Certain Bonds (the "Insured Bonds") may be insured or guaranteed
by AMBAC Indemnity Corporation ("AMBAC"), Asset Guaranty Reinsurance Company
("Asset Guaranty"), Capital Guaranty Insurance Company ("CGIC"), Capital
Markets Assurance Corp. ("CAPMAC"), Connie Lee Insurance Company ("Connie
Lee"), Financial Guaranty Insurance Company "Financial Guaranty"), Financial
Security Assurance Inc. ("FSA"), or MBIA Insurance Corporation ("MBIA")
(collectively, the "Insurance Companies"). The claims-paying ability of each of
these companies, unless otherwise indicated, is rated AAA by Standard & Poor's
or another acceptable national rating service. The ratings are subject to
change at any time at the discretion of the rating agencies. In determining
whether to insure bonds, the Insurance Companies severally apply their own
standards. The cost of this insurance is borne either by the issuers or
previous owners of the bonds or by the Sponsor. The insurance policies are non-
cancellable and will continue in force so long as the Insured Bonds are
outstanding and the insurers remain in business. The insurance policies
guarantee the timely payment of principal and interest on but do not guarantee
the market value of the Insured Bonds or the value of the Units. The insurance
policies generally do not provide for accelerated payments of principal or,
except in the case of any portfolio insurance policies, cover redemptions
resulting from events of taxability. If the issuer of any Insured Bond should
fail to make an interest or principal payment, the insurance policies generally
provide that the Trustee or its agent shall give notice of nonpayment to the
Insurance Company or its agent and provide evidence of the Trustee's right to
receive payment. The Insurance Company is then required to disburse the amount
of the failed payment to the Trustee or its agent and is thereafter subrogated
to the Trustee's right to receive payment from the issuer.
 
  The following are brief descriptions of certain of the insurance companies
that may insure or guarantee certain Bonds. The financial information presented
for each company has been determined on a statutory basis and is unaudited.
 
  AMBAC is a Wisconsin-domiciled stock insurance corporation, regulated by the
Office of the Commissioner of Insurance of the State of Wisconsin, and licensed
to do business in 50 states, the District of Columbia, the Territory of Guam
and the Commonwealth of Puerto Rico, with admitted assets of approximately
$2,736,000,000 (audited) and statutory capital of approximately $1,548,000,000

<PAGE>
 
(audited) as of June 30, 1997. Statutory capital consists of AMBAC's
policyholders' surplus and statutory contingency reserve. AMBAC is a wholly
owned subsidiary of AMBAC Inc., a 100% publicly-held company. Moody's, Standard
& Poor's and Fitch have each assigned a triple-A claims-paying ability rating
to AMBAC.
 
  AMBAC has entered into pro rata reinsurance agreements under which a
percentage of the insurance underwritten pursuant to certain municipal bond
insurance programs of AMBAC has been and will be assumed by a number of foreign
and domestic unaffiliated reinsurers.
 
  AMBAC has obtained a ruling from the Internal Revenue Service to the effect
that the insuring of an obligation by AMBAC will not affect the treatment for
federal income tax purposes of interest on such obligation and that insurance
proceeds representing maturing interest paid by AMBAC under policy provisions
substantially identical to those contained in its municipal bond insurance
policy shall be treated for federal income tax purposes in the same manner as
if such payments were made by the issuer of the Bonds.
 
  Asset Guaranty is a New York State insurance company licensed to write
financial guarantee, credit, residual value and surety insurance. Asset
Guaranty commenced operations in mid-1988 by providing reinsurance to several
major monoline insurers. Asset Guaranty also issued limited amounts of primary
financial guaranty insurance, but not in direct competition with the primary
mono-line companies for which it acts as a reinsurer. The parent holding
company of Asset Guaranty, Asset Guarantee Inc. (AGI), merged with Enhance
Financial Services (EFS) in June, 1990 to form Enhance Financial Services Group
Inc. (EFSG). The two main, 100%-owned subsidiaries of EFSG, Asset Guaranty and
Enhance Reinsurance Company (ERC), share common management and physical
resources. As of April 30, 1996 EFSG is 55.3% owned by the public, 30.2% by
U.S. WEST Inc., 8.9% by senior management and 5.6% by Swiss Reinsurance
Company. Both ERC and Asset Guaranty are rated "AAA" for claims paying ability
by Duff & Phelps. ERC is rated triple-A for claims-paying ability by both
Standard & Poor's and Moody's. Asset Guaranty received a "AA" claims-paying-
ability rating from Standard & Poor's during August 1993, but remains unrated
by Moody's. As of March 31, 1996 Asset Guaranty had admitted assets of
approximately $187,000,000 and policyholders' surplus of approximately
$82,000,000.
 
  CAPMAC commenced operations in December, 1987 as the second monoline
financial guaranty insurance company (after FSA) organized solely to insure
non-municipal obligations. CAPMAC, a New York corporation, is a wholly-owned
subsidiary of CAPMAC Holdings, Inc. (CHI), which was sold in 1992 by Citibank
(New York State) to a group of 12 investors led by the following: Dillon Read's
Saratoga Partners II; L.P. (Saratoga), an acquisition fund; Caprock Management,
Inc., representing Rockefeller family interests; Citigrowth Fund, a Citicorp
venture capital group; and CAPMAC senior management and staff. These groups
control approximately 70% of the stock of CHI. CAPMAC had traditionally
specialized in guaranteeing consumer loan and trade receivable asset-backed
securities. Under the new ownership group CAPMAC intends to become involved in
the municipal bond insurance business, as well as their traditional non-
municipal business. As of March 31, 1995 CAPMAC's admitted assets were
approximately $210,000,000 and its policyholders' surplus was approximately
$138,000,000.
 
  FSA is a monoline insurance company incorporated in 1984 under the laws of
the State of New York and is licensed to engage in the financial guaranty
insurance business in all 50 states, the District of Columbia and Puerto Rico.
 
  FSA is a wholly owned subsidiary of Financial Security Assurance Holdings
Ltd. ("Holdings"), a New York Stock Exchange listed company. Major shareholders
of Holdings include Fund American Enterprises Holdings, Inc., US WEST Capital
Corporation and Tokio Marine and Fire Insurance Co., Ltd. No shareholder of
Holdings is obligated to pay any debt of FSA or any claim under any insurance
policy issued by FSA or to make any additional contribution to the capital of
FSA.
 
  Pursuant to an intercompany agreement, liabilities on financial guaranty
insurance written or reinsured from third parties, by FSA or any of its
domestic operating insurance company subsidiaries are reinsured among such
companies on an agreed upon percentage substantially proportional to their
respective capital, surplus and reserves, subject to applicable statutory risk
limitations. In addition, FSA reinsures a portion of its liabilities under
certain of its financial guaranty insurance policies with other reinsurers
under various quota-share treaties and on a transaction-by-transaction basis.
Such reinsurance is utilized by FSA as a risk management device and to comply
with certain statutory and rating agency requirements; it does not alter or
limit FSA's obligations under any financial guaranty insurance policy. As of
June 30, 1997, total shareholders equity of FSA and its wholly-owned
subsidiaries was (unaudited) $861,209,000 and total unearned premium reserves
was (unaudited) $401,251,000.
 
  Connie Lee, a stock insurance company incorporated in Wisconsin, is a wholly-
owned subsidiary of College Construction Loan Insurance Corporation (formerly
College Construction Loan Insurance Association), a stockholder-owned District
of Columbia insurance holding company whose creation was authorized by the 1986
amendments to the Higher Education Act to provide financial guaranties for
educational facilities. The Omnibus Consolidated Appropriations Act, 1997 (the
"Privatization Act"), enacted by Congress and signed by the President on
September 30, 1996, has repealed substantially all of the provisions of the
Higher Education Act which previously dictated the structure and operational
authorities of Connie Lee. Also in accordance with the Privatization Act,
Construction Loan Insurance Corporation repurchased on February 27, 1997 all of
the 1,914,800 shares (14% of total ownership) of the stock of Construction Loan
Insurance Corporation previously owned by the United States Department of
Education. Construction Loan Insurance Corporation is currently owned by a
group of stockholders that includes Student Loan Marketing Association ("Sallie
Mae") and various institutional
 
                                      B-10

investors. Construction Loan Insurance Corporation has engaged the firm of
Wasserstein Perella & Co., Inc. as its financial advisor to assist it in
exploring a range of strategic options, including a potential sale that would
include Connie Lee. It cannot be predicted whether a sale or similar
transaction, if pursued, will be accomplished. Any sale of Connie Lee would be
subject to the approval of the Commission of Insurance of the State of
Wisconsin. NEITHER CONNIE LEE NOR CONSTRUCTION LOAN INSURANCE CORPORATION IS AN
AGENCY OR INSTRUMENTALITY OF THE UNITED STATES GOVERNMENT, AND THE UNITED
STATES GOVERNMENT IS NOT AN INVESTOR IN CONNIE LEE OR CONSTRUCTION LOAN
INSURANCE CORPORATION. THE OBLIGATIONS OF CONNIE LEE ARE NOT OBLIGATIONS OF THE
UNITED STATES GOVERNMENT OR GUARANTEED IN ANY WAY BY THE FULL FAITH AND CREDIT
OF THE UNITED STATES GOVERNMENT.
 
  As of June 30, 1997, the total policyholders' surplus of Connie Lee was
$119,184,800 (unaudited) and total admitted assets were $237,343,071
(unaudited), as reported to the Commissioner of Insurance of the State of
Wisconsin in Connie Lee's financial statements prepared in accordance with
statutory accounting principals applicable to insurance companies. Copies of
these financial statements are available from Connie Lee upon request.
 
  Financial Guaranty Insurance Company ("Financial Guaranty") is a wholly-owned
subsidiary of FGIC Corporation ("Corporation"), a Delaware holding company. The
Corporation is a wholly-owned subsidiary of General Electric Capital
Corporation ("GECC"). Neither the Corporation nor GECC is obligated to pay the
debts of or the claims against Financial Guaranty. Financial Guaranty is
domiciled in the State of New York and is subject to regulation by the State of
New York Insurance Department. As of June 30, 1997, the total capital and
surplus of Financial Guaranty was approximately $1,164,694,536. In addition,
Financial Guaranty is currently licensed to write insurance in all 50 states
and the District of Columbia.
 
  MBIA is the principal operating subsidiary of MBIA Inc. The principal
shareholders of MBIA Inc. were originally Aetna Casualty and Surety Company,
The Fund American Companies, Inc., subsidiaries of CIGNA Corporation and Credit
Local de France, CAECL, S.A. These principal shareholders now own approximately
13% of the outstanding common stock of MBIA Inc., following a series of four
public equity offerings over a five-year period. MBIA is domiciled in the State
of New York and licensed to do business in, and subject to regulation under,
the laws of all 50 states, the District of Columbia, the Commonwealth of Puerto
Rico, the Commonwealth of the Northern Mariana Islands, the Virgin Islands of
the United States and the Territory of Guam. As of December 31, 1996, MBIA had
admitted assets of approximately $4,400,000,000 (audited), total liabilities of
approximately $3,000,000,000 (audited), and policyholders' surplus of
approximately $1,400,000,000 (audited), prepared in accordance with statutory
accounting practices prescribed or permitted by insurance regulatory
authorities.
 
  Insurance companies are subject to regulation and supervision in the
jurisdictions in which they do business under statutes which delegate
regulatory, supervisory and administrative powers to state insurance
commissioners. This regulation, supervision and administration relate, among
other things, to: the standards of solvency which must be met and maintained;
the licensing of insurers and their agents; the nature of and limitations on
investments; deposits of securities for the benefit of policyholders; approval
of policy forms and premium rates; periodic examinations of the affairs of
insurance companies; annual and other reports required to be filed on the
financial condition of insurers or for other purposes; and requirements
regarding reserves for unearned premiums, losses and other matters. Regulatory
agencies require that premium rates not be excessive, inadequate or unfairly
discriminatory. Insurance regulation in many states also includes "assigned
risk" plans, reinsurance facilities, and joint underwriting associations, under
which all insurers writing particular lines of insurance within the
jurisdiction must accept, for one or more of those lines, risks unable to
secure coverage in voluntary markets. A significant portion of the assets of
insurance companies is required by law to be held in reserve against potential
claims on policies and is not available to general creditors.
 
  Although the Federal government does not regulate the business of insurance,
Federal initiatives can significantly impact the insurance business. Current
and proposed Federal measures which may significantly affect the insurance
business include pension regulation (ERISA), controls on medical care costs,
minimum standards for no-fault automobile insurance, national health insurance,
personal privacy protection, tax law changes affecting life insurance companies
or the relative desirability of various personal investment vehicles and repeal
of the current antitrust exemption for the insurance business. (If this
exemption is eliminated, it will substantially affect the way premium rates are
set by all property-liability insurers.) In addition, the Federal government
operates in some cases as a co-insurer with the private sector insurance
companies.
 
  Insurance companies are also affected by a variety of state and Federal
regulatory measures and judicial decisions that define and extend the risks and
benefits for which insurance is sought and provided. These include judicial
redefinitions of risk exposure in areas such as products liability and state
and Federal extension and protection of employee benefits, including pension,
workers' compensation, and disability benefits. These developments may result
in short-term adverse effects on the profitability of various lines of
insurance. Longer-term adverse effects can often be minimized through prompt
repricing of coverages and revision of policy terms. In some instances, these
developments may create new opportunities for business growth. All insurance
companies write policies and set premiums based on actuarial assumptions about
mortality, injury, the occurrence of accidents and other insured events. These
 
                                      B-11
<PAGE>
 
assumptions, while well supported by past experience, necessarily do not take
account of future events. The occurrence in the future of unforeseen
circumstances could affect the financial condition of one or more insurance
companies. The insurance business is highly competitive and with the
deregulation of financial service businesses, it should become more
competitive. In addition, insurance companies may expand into non-traditional
lines of business which may involve different types of risks.
 
  The above financial information relating to the Insurance Companies has been
obtained from publicly available information. No representation is made as to
the accuracy or adequacy of the information or as to the absence of material
adverse changes since the information was made available to the public.
 
  LITIGATION AND LEGISLATION. To the best knowledge of the Sponsor, there is no
litigation pending as of the Date of Deposit in respect of any Bonds which
might reasonably be expected to have a material adverse effect upon the Trust.
At any time after the Date of Deposit, litigation may be initiated on a variety
of grounds, or legislation may be enacted, with respect to Bonds in the Trust.
Litigation, for example, challenging the issuance of pollution control revenue
bonds under environmental protection statutes may affect the validity of Bonds
or the tax-free nature of their interest. While the outcome of litigation of
this nature can never be entirely predicted, opinions of bond counsel are
delivered on the date of issuance of each Bond to the effect that the Bond has
been validly issued and that the interest thereon is exempt from regular
Federal income tax. In addition, other factors may arise from time to time
which potentially may impair the ability of issuers to make payments due on the
Bonds.
 
  Under the Federal Bankruptcy Act, a political subdivision or public agency or
instrumentality of any state, including municipalities, may proceed to
restructure or otherwise alter the terms of its obligations, including those of
the type comprising the Trust's Portfolio. The Sponsor is unable to predict
what effect, if any, this legislation might have on the Trust.
 
  From time to time Congress considers proposals to tax the interest on state
and local obligations, such as the Bonds. The Supreme Court clarified in South
Carolina v. Baker (decided April 20, 1988) that the U.S. Constitution does not
prohibit Congress from passing a nondiscriminatory tax on interest on state and
local obligations. This type of legislation, if enacted into law, could
adversely affect an investment in Units. Holders are urged to consult their own
tax advisers.
 
  TAX EXEMPTION. In the opinion of bond counsel rendered on the date of
issuance of each Bond, the interest on each Bond is excludable from gross
income under existing law for regular Federal income tax purposes (except in
certain circumstances depending on the Holder) but may be subject to state and
local taxes. As discussed under Taxes below, interest on some or all of the
Bonds may become subject to regular Federal income tax, perhaps retroactively
to their date of issuance, as a result of changes in Federal law or as a result
of the failure of issuers (or other users of the proceeds of the Bonds) to
comply with certain ongoing requirements.
 
  Moreover, the Internal Revenue Service is expanding its examination program
with respect to tax-exempt bonds. The expanded examination program will consist
of, among other measures, increased enforcement against abusive transactions,
broader audit coverage (including the expected issuance of audit guidelines)
and expanded compliance achieved by means of expected revisions to the tax-
exempt bond information return forms. At this time, it is uncertain whether the
tax exempt status of any of the Bonds would be affected by such proceedings, or
whether such effect, if any, would be retroactive.
 
  In certain cases, a Bond may provide that if the interest on the Bond should
ultimately be determined to be taxable, the Bond would become due and payable
by its issuer, and, in addition, may provide that any related letter of credit
or other security could be called upon if the issuer failed to satisfy all or
part of its obligation. In other cases, however, a Bond may not provide for the
acceleration or redemption of the Bond or a call upon the related letter of
credit or other security upon a determination of taxability. In those cases in
which a Bond does not provide for acceleration or redemption or in which both
the issuer and the bank or other entity issuing the letter of credit or other
security are unable to meet their obligations to pay the amounts due on the
Bond as a result of a determination of taxability, the Trustee would be
obligated to sell the Bond and, since it would be sold as a taxable security,
it is expected that it would have to be sold at a substantial discount from
current market price. In addition, as mentioned above, under certain
circumstances Holders could be required to pay income tax on interest received
prior to the date on which the interest is determined to be taxable.
 
THE UNITS
 
  On the Date of Deposit, each Unit in a Trust represented a fractional
undivided interest in the principal and net income of such Trust as is set
forth in Part A, "Summary of Essential Information."
 
  If any Units are redeemed after the date of this Prospectus by the Trustee,
the principal amount of Bonds in the affected Trust will be reduced by an
amount allocable to redeemed Units and the fractional undivided interest in the
affected Trust represented by each unredeemed Unit will be increased. Units
will remain outstanding until redeemed upon tender to the Trustee by any Unit
holder, which may include the Sponsor, or until the termination of the Trust
Agreement. (See "Amendment and Termination of the Trust Agreement--
Termination.")

TAXES
 
  The following discussion addresses only the tax consequences of Units held as
capital assets and does not address the tax consequences of Units held by
dealers, financial institutions or insurance companies.
 
  In the opinion of Battle Fowler LLP, special counsel for the Sponsor, under
existing law:
 
    The Trusts are not associations taxable as corporations for Federal
  income tax purposes, and income received by the Trusts will be treated as
  the income of the Unit holders ("Holders") in the manner set forth below.
 
    Each Holder of Units of a Trust will be considered the owner of a pro
  rata portion of each Bond in the Trust under the grantor trust rules of
  Sections 671-679 of the Internal Revenue Code of 1986, as amended (the
  "Code"). In order to determine the face amount of a Holder's pro rata
  portion of each Bond on the Date of Deposit, see "Aggregate Principal"
  under "Portfolio of Securities". The total cost to a Holder of his Units,
  including sales charges, is allocated to his pro rata portion of each Bond,
  in proportion to the fair market values thereof on the date the Holder
  purchases his Units, in order to determine his tax cost for his pro rata
  portion of each Bond. In order for a Holder who purchases his Units on the
  Date of Deposit to determine the fair market value of his pro rata portion
  of each Bond on such date, see "Cost of Securities to Trust" under
  "Portfolio of Securities".
 
    Each Holder of Units of a Trust will be considered to have received the
  interest on his pro rata portion of each Bond when interest on the Bond is
  received by the Trust. In the opinion of bond counsel (delivered on the
  date of issuance of each Bond), such interest will be excludable from gross
  income for regular Federal income tax purposes (except in certain limited
  circumstances referred to below). Amounts received by a Trust pursuant to a
  bank letter of credit, guarantee or insurance policy with respect to
  payments of principal, premium or interest on a Bond in the Trust will be
  treated for Federal income tax purposes in the same manner as if such
  amounts were paid by the issuer of the Bond.
 
    The Trusts may contain Bonds which were originally issued at a discount
  ("original issue discount"). The following principles will apply to each
  Holder's pro rata portion of any Bond originally issued at a discount. In
  general, original issue discount is defined as the difference between the
  price at which a debt obligation was issued and its stated redemption price
  at maturity. Original issue discount on a tax-exempt obligation issued
  after September 3, 1982, is deemed to accrue as tax-exempt interest over
  the life of the obligation under a formula based on the compounding of
  interest. Original issue discount on a tax-exempt obligation issued before
  July 2, 1982 is deemed to accrue as tax-exempt interest ratably over the
  life of the obligation. Original issue discount on any tax-exempt
  obligation issued during the period beginning July 2, 1982 and ending
  September 3, 1982 is also deemed to accrue as tax-exempt interest over the
  life of the obligation, although it is not clear whether such accrual is
  ratable or is determined under a formula based on the compounding of
  interest. If a Holder's tax cost for his pro rata portion of a Bond issued
  with original issue discount is greater than its "adjusted issue price" but
  less than its stated redemption price at maturity (as may be adjusted for
  certain payments), the Holder will be considered to have purchased his pro
  rata portion of the Bond at an "acquisition premium." A Holder's adjusted
  tax basis for his pro rata portion of a Bond issued with original issue
  discount will include original issue discount accrued during the period
  such Holder held his Units. Such increases to the Holder's tax basis in his
  pro rata portion of the Bond resulting from the accrual of original issue
  discount, however, will be reduced by the amortization of any such
  acquisition premium.
 
    If a Holder's tax basis for his pro rata portion of a Bond in the
  Holder's Trust exceeds the redemption price at maturity thereof (subject to
  certain adjustments), the Holder will be considered to have purchased his
  pro rata portion of the Bond with "amortizable bond premium". The Holder is
  required to amortize such bond premium over the term of the Bond. Such
  amortization is only a reduction of basis for his pro rata portion of the
  Bond and does not result in any deduction against the Holder's income.
  Therefore, under some circumstances, a Holder may recognize taxable gain
  when his pro rata portion of a Bond is disposed of for an amount equal to
  or less than his original tax basis therefor.
 
    A Holder will recognize taxable gain or loss when all or part of his pro
  rata portion of a Bond in his Trust is disposed of by the Trust for an
  amount greater or less than his adjusted tax basis. Any such taxable gain
  or loss will be capital gain or loss (assuming that the Units are held as
  capital assets), except that any gain from the disposition of a Holder's
  pro rata portion of a Bond acquired by the Holder at a "market discount"
  (i.e., where the Holder's original basis for his pro rata portion of the
  Bond (plus any original issue discount which will accrue thereon until its
  maturity) is less than its stated redemption price at maturity) would be
  treated as ordinary income to the extent the gain does not exceed the
  accrued market discount. Capital gains are generally taxed at the same rate
  as ordinary income. However, the excess of net long-term capital gains over
  net short-term capital losses may be taxed at a lower rate than ordinary
  income for certain noncorporate taxpayers. A capital gain or loss is long-
  term if the asset is held for more than one year and short-term if held for
  one year or less. A reduced tax rate for noncorporate taxpayers may be
  available for assets held for more than 18 months. The deduction of capital
  losses is subject to limitations. A Holder will also be considered to have
  disposed of all or part of his pro rata portion of each Bond when he sells
  or redeems all or some of his Units.
 
    Under the income tax laws of the State and City of New York, the Trust is
  not an association taxable as a corporation and income received by each
  Trust will be treated as the income of the Holders in the same manner as
  for Federal income tax purposes, but will not necessarily be tax-exempt.
 
                                      B-13
<PAGE>
 
    Under Section 265 of the Code, a Holder (except a corporate Holder) is
  not entitled to a deduction for his pro rata share of fees and expenses of
  a Trust because the fees and expenses are incurred in connection with the
  production of tax-exempt income. Further, if borrowed funds are used by a
  Holder to purchase or carry Units of any Trust, interest on such
  indebtedness will not be deductible for Federal income tax purposes. In
  addition, 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 state tax purposes.
 
  From time to time proposals are introduced in Congress and state legislatures
which, if enacted into law, could have an adverse impact on the tax-exempt
status of the Bonds. It is impossible to predict whether any legislation in
respect of the tax status of interest on such obligations may be proposed and
eventually enacted at the Federal or state level.
 
  The foregoing discussion relates only to Federal and certain aspects of New
York State and City income taxes. Depending on their state of residence,
Holders may be subject to state and local taxation and should consult their own
tax advisers in this regard.
 
  Interest on certain tax-exempt bonds issued after August 7, 1986 will be a
preference item for purposes of the alternative minimum tax ("AMT"). The
Sponsor believes that interest (including any original issue discount) on the
Bonds should not be subject to the AMT for individuals or corporations under
this rule. A corporate Holder should be aware, however, that the accrual or
receipt of tax-exempt interest not subject to the AMT may give rise to an
alternative minimum tax liability (or increase an existing liability) because
the interest income will be included in the corporation's "adjusted current
earnings" for purposes of the adjustment to alternative minimum taxable income
required by Section 56(g) of the Code.
 
  In addition, interest on the Bonds must be taken into consideration in
computing the portion, if any, of social security benefits that will be
included in an individual's gross income and subject to Federal income tax.
Holders are urged to consult their own tax advisers concerning an investment in
Units.
 
  At the time of issuance of each Bond, an opinion relating to the validity of
the Bond and to the exemption of interest thereon from regular Federal income
taxes was or will be rendered by bond counsel. Neither the Sponsor nor Battle
Fowler LLP have made or will make any review of the proceedings relating to the
issuance of the Bonds or the basis for these opinions. The tax exemption is
dependent upon the issuer's (and other users') compliance with certain ongoing
requirements, and the opinion of bond counsel assumes that these requirements
will be complied with. However, there can be no assurance that the issuer (and
other users) will comply with these requirements, in which event the interest
on the Bond could be determined to be taxable retroactively to the date of
issuance.
 
  In the case of certain of the Bonds, the opinions of bond counsel indicate
that interest on such Bonds received by a "substantial user" of the facilities
being financed with the proceeds of such Bonds, or persons related thereto, for
periods while such Bonds are held by such a user or related person, will not be
exempt from regular Federal income taxes, although interest on such Bonds
received by others would be exempt from regular Federal income taxes.
"Substantial user" is defined under U.S. Treasury Regulations to include only a
person whose gross revenue derived with respect to the facilities financed by
the issuance of bonds is more than 5% of the total revenue derived by all users
of such facilities, or who occupies more than 5% of the usable area of such
facilities or for whom such facilities or a part thereof were specifically
constructed, reconstructed or acquired. "Related persons" are defined to
include certain related natural persons, affiliated corporations, partners and
partnerships. Similar rules may be applicable for state tax purposes.
 
  After the end of each calendar year, the Trustee will furnish to each Holder
an annual statement containing information relating to the interest received by
the Trust on the Bonds, the gross proceeds received by the Trust from the
disposition of any Bond (resulting from redemption or payment at maturity of
any Bond or the sale by the Trust of any Bond), and the fees and expenses paid
by the Trust. The Trustee will also furnish annual information returns to each
Holder and to the Internal Revenue Service. Holders are required to report to
the Internal Revenue Service the amount of tax-exempt interest received during
the year.
 
EXPENSES AND CHARGES
 
  INITIAL EXPENSES
 
  All or some portion of the expenses incurred in establishing each Trust,
including the cost of the initial preparation of documents relating to a Trust,
Federal and State registration fees, the initial fees and expenses of the
Trustee, legal expenses and any other out-of-pocket expenses will be paid by
the Trust, and amortized over five years. Any balance of the expenses incurred
in establishing a Trust, as well as advertising and selling expenses and other
out-of-pocket expenses will be paid at no cost to the Trusts.
 
  TRUSTEE'S, SPONSOR'S AND EVALUATOR'S FEES
 
  The Trustee will receive for its ordinary recurring services to a Trust an
annual fee in the amount set forth under Part A, "Summary of Essential
Information." For a discussion of the services performed by the Trustee
pursuant to its obligations under the Trust Agreement, see "Rights of Unit
Holders." The Trustee will receive the benefit of any reasonable cash balances
in the Income and Principal Accounts.
 
                                      B-14
<PAGE>
 
  There are no management fees and the Sponsor earns only a nominal Portfolio
Supervision fee (the "Supervision Fee"), which is earned for Portfolio
supervisory services. This fee is based upon the greatest face amount of Bonds
in the Trust at any time during the calendar year with respect to which the fee
is being computed.
 
  The Supervision Fee, which is not to exceed the amount set forth in Part A--
"Summary of Essential Information", may exceed the actual costs of providing
Portfolio supervisory services for such Trust, but at no time will the total
amount the Sponsor receives for Portfolio supervisory services rendered to all
series of Tax Exempt Securities Trust in any calendar year exceed the aggregate
cost to them of supplying such services in such year. In addition, the Sponsor
may also be reimbursed for bookkeeping and other administrative services
provided to the Trust in amounts not exceeding their costs of providing these
services.
 
  The Evaluator will receive a fee in the amount set forth under Part A,
"Summary of Essential Information," for each evaluation of the Bonds in a
Trust. For a discussion of the services performed by the Evaluator pursuant to
its obligations under the Trust Agreement, see "Evaluator--Responsibility" and
"Public Offering--Offering Price."
 
  Any of such 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" or, if such Index is no longer published, in
a similar Index to be determined by the Trustee and the Sponsor.
 
  OTHER CHARGES
 
  The following additional charges are or may be incurred by a Trust: all
expenses of the Trustee (including fees and expenses of counsel and auditors)
incurred in connection with its activities under the Trust Agreement, including
reports and communications to Unit holders; expenses and costs of any action
undertaken by the Trustee to protect a 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 gross negligence, bad faith or willful
misconduct on its part, arising out of or in connection with its acceptance or
administration of a Trust; to the extent lawful, expenses (including legal,
accounting and printing expenses) of maintaining registration or qualification
of the Units and/or a Trust under Federal or state securities laws subsequent
to initial registration so long as the Sponsor maintains a market for the Units
and all taxes and other governmental charges imposed upon the Bonds or any part
of a Trust (no such taxes or charges are being levied or made or, to the
knowledge of the Sponsor, 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 Bonds in order to make
funds available to pay all expenses.
 
PUBLIC OFFERING
 
OFFERING PRICE
 
  During the initial public offering period, the Public Offering Price of the
Units of a Trust is determined by adding to the Evaluator's determination of
the aggregate OFFERING price of the Bonds per Unit a sales charge equal to a
percentage of the Public Offering Price of the Units of the Trust, as set forth
in the table below. After the initial public offering period, the Public
Offering Price of the Units of a Trust will be determined by adding to the
Evaluator's determination of the aggregate BID price of the Bonds per Unit a
sales charge equal to 5.00% of the Public Offering Price (5.263% of the
aggregate bid price of the Bonds per Unit). A proportionate share of accrued
and undistributed interest on the Bonds in a Trust at the date of delivery of
the Units of such Trust to the purchaser is also added to the Public Offering
Price. (See "Rights of Unit Holders--Distribution of Interest and Principal.")
 
  During the initial public offering period, the sales charge and dealer
concession for the Trusts will be reduced as follows:

</TABLE>
 
The Sponsor may at any time change the amount by which the sales charge is
reduced, or discontinue the discount completely.
 
  Pursuant to employee benefit plans, Units of a Trust are available to
employees of the Sponsor and its subsidiaries, affiliates and employee-related
discounts, during the initial public offering period, at a Public Offering
Price equal to the Evaluator's determination of the aggregate offering price of
the Bonds of a Trust per Unit plus a sales charge of .50% of the Public
Offering Price and after the initial public offering period, at a Public
Offering Price equal to the Evaluator's determination of the aggregate bid
price of the Bonds of a Trust

per Unit plus a sales charge of .50% of the Public Offering Price. Sales
through such plans to employees of the Sponsor result in less selling effort
and selling expenses than sales to the general public. Participants in the
Smith Barney Asset One  SM Program may purchase Units of the Trust at a Public
Offering Price equal to the Evaluator's determination of the aggregate offering
price of the Bonds of a Trust per Unit during the initial offering period and
after the initial offering period at a Public Offering Price equal to the
Evaluator's determination of the aggregate bid price of the Bonds of a Trust
per Unit. Participants in the Smith Barney Asset One  SM Program are subject to
certain fees for specified securities brokerage and execution services.
 
METHOD OF EVALUATION
 
  During the initial public offering period, the aggregate offering price of
the Bonds is determined by the Evaluator (1) on the basis of current offering
prices for the Bonds*, (2) if offering prices are not available for any Bonds,
on the basis of current offering prices for comparable securities, (3) by
appraisal, or (4) by any combination of the above. Such determinations are made
each business day as of the Evaluation Time set forth in the "Summary of
Essential Information," in Part A, effective for all sales made subsequent to
the last preceding determination. Following the initial public offering period,
the aggregate bid price of the Bonds (which is used to calculate the price at
which the Sponsor repurchases and sells Units in the secondary market and the
Redemption Price at which Units may be redeemed) will be determined by the
Evaluator (1) on the basis of the current bid prices for the Bonds*, (2) if bid
prices are not available for any Bonds, on the basis of current bid prices of
comparable securities, (3) by appraisal, or (4) by any combination of the
above. Such determinations will be made each business day as of the Evaluation
Time set forth in the "Summary of Essential Information," in Part A, effective
for all sales made subsequent to the last preceding determination. The term
"business day," as used herein shall exclude Saturdays, Sundays and any day on
which the New York Stock Exchange is closed. The difference between the bid and
offering prices of the Bonds may be expected to average approximately 1 1/2% of
principal amount. In the case of actively traded securities, the difference may
be as little as 1/2 of 1%, and in the case of inactively traded securities such
difference will usually not exceed 3%. The price at which Units may be
repurchased by the Sponsor in the secondary market could be less than the price
paid by the Unit holder. On the Date of Deposit for each Trust the aggregate
current offering price of such Bonds per Unit exceeded the bid price of such
Bonds per Unit by the amounts set forth under "Summary of Essential
Information" in Part A. For information relating to the calculation of the
Redemption Price per Unit, which is also based upon the aggregate bid price of
the underlying Bonds and which may be expected to be less than the Public
Offering Price per Unit, see "Rights of Unit Holders--Redemption of Units."
 
DISTRIBUTION OF UNITS
 
  During the initial public offering period Units of a Trust will be
distributed to the public at the Public Offering Price determined in the manner
provided above (see "Public Offering--Offering Price") through the Underwriters
and dealers. The initial public offering period is 30 days unless all Units of
a Trust are sold prior thereto, in which case the initial public offering
period terminates with the sale of all Units. So long as all Units initially
offered have not been sold, the Sponsor may extend the initial public offering
period for up to four additional successive 30-day periods. Upon completion of
the initial public offering, Units which remain unsold or which may be acquired
in the secondary market (see "Public Offering--Market for Units") may be
offered by this Prospectus at the Public Offering Price determined in the
manner provided above (see "Public Offering--Offering Price").
 
  It is the Sponsor's intention to qualify Units of a Trust for sale through
the Underwriters and dealers who are members of the National Association of
Securities Dealers, Inc. Units of a State Trust will be offered for sale only
in the State for which the Trust is named, except that Units of a New York
Trust will also be offered for sale to residents of the State of Connecticut,
the State of Florida and the Commonwealth of Puerto Rico. Units will initially
be sold to dealers at prices which represent a concession equal to the amount
designated in the tables under "Public Offering--Offering Price" herein, for a
Trust with an unreduced sales charge as specified in Part A--"The Public
Offering Price." The Sponsor reserves the right to change the amount of the
concession to dealers from time to time. After the initial offering period the
dealer concession is negotiated on a case-by-case basis.
 
  Sales will be made only with respect to whole Units, and the Sponsor reserves
the right to reject, in whole or in part, any order for the purchase of Units.
A purchaser does not become a Unit holder (Certificate holder) or become
entitled to exercise the rights of a Unit holder (including the right to redeem
his Units) until he has paid for his Units. Generally, such payment must be
made within five business days after an order for the purchase of Units has
been placed. The price paid by a Unit holder is the Public Offering Price in
effect at the time his order is received, plus accrued interest (see "Public
Offering--Method of Evaluation"). This price may be different from the Public
Offering Price in effect on any other day, including the day on which he made
payment for the Units.
 
MARKET FOR UNITS
  Following the initial public offering period the Sponsor, although not
obligated to do so, presently intends to maintain a market for the Units of a
Trust and continuously to offer to purchase such Units at prices based upon the
aggregate bid price of the underlying Bonds. For information relating to the
method and frequency of the Evaluator's determination of the aggregate bid
price of the underlying
- -------
* Current offering or bid prices of the Deposited Units, if any, are based on
  prevailing weekly evaluations of the obligations underlying such Deposited
  Units.
 
                                      B-16
<PAGE>
 
Bonds, see "Public Offering--Method of Evaluation." The Sponsor may cease to
maintain such a market at any time and from time to time without notice if the
supply of Units of a Trust of this Series exceeds demand or for any other
reason. In this event the Sponsor may nonetheless purchase Units, as a service
to Unit holders, at prices based on the current Redemption Price of those
Units. In the event that a market is not maintained for the Units of a Trust, a
Unit holder of such Trust desiring to dispose of his 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 Bonds. The
aggregate bid price of the underlying Bonds of a Trust may be expected to be
less than the aggregate offering price.
 
EXCHANGE OPTION
 
  Unit holders may elect to exchange any or all of their Units of this series
for units of one or more of any series of Tax Exempt Securities Trust (the
"Exchange Trust") available for sale in the state in which the Unit holder
resides at a Public Offering Price for the units of the Exchange Trust to be
acquired based on a fixed sales charge of $25 per unit. The Sponsor reserves
the right to modify, suspend or terminate this plan at any time without further
notice to Unit holders. Therefore, there is no assurance that a market for
units will in fact exist on any given date on which a Unit holder wishes to
sell his Units of this series and thus there is no assurance that the Exchange
Option will be available to a Unit holder. Exchanges will be effected in whole
units ONLY. If the proceeds from the Units being surrendered are less than the
cost of a whole number of units being acquired, the exchanging Holder will be
permitted to add cash in an amount to round up to the next highest number of
whole units.
 
  An exchange of Units pursuant to the Exchange Option for units of an Exchange
Trust will generally constitute a "taxable event" under the Code, i.e., a
Holder will recognize a gain or loss at the time of exchange. However, an
exchange of Units of this Trust for units of any other series of the Tax Exempt
Securities Trust which are grantor trusts for U.S. Federal income tax purposes
will not constitute a taxable event to the extent that the underlying
securities in each trust do not differ materially either in kind or in extent.
Unit holders are urged to consult their own tax advisors as to the tax
consequences to them of exchanging Units in particular cases.
 
  Units of the Exchange Trust will be sold under the Exchange Option at the bid
prices of the underlying securities in the particular portfolio involved per
unit plus a fixed charge of $25 per unit. As an example, assume that a Unit
holder, who has three units of a trust with a current price of $1,020 per unit
based on the bid prices of the underlying securities, desires to exchange his
Units for units of a series of an Exchange Trust with a current price of $880
per unit based on the bid prices of the underlying securities. In this example,
the proceeds from the Unit holder's units will aggregate $3,060. Since only
whole units of an Exchange Trust may be purchased under the Exchange Option,
the Unit holder would be able to acquire four units in the Exchange Trust for a
total cost of $3,620 ($3,520 for the units and $100 for the sales charge).
 
REINVESTMENT PROGRAMS
 
  Distributions of interest and principal, if any, are made to Unit holders
monthly. The Unit holder will have the option of either receiving his monthly
income check from the Trustee or participating in one of the reinvestment
programs offered by the Sponsor provided such Unit holder meets the minimum
qualifications of the reinvestment program and such program lawfully qualifies
for sale in the jurisdiction in which the Unit holder resides. Upon enrollment
in a reinvestment program, the Trustee will direct monthly interest
distributions and principal distributions, if any, to the reinvestment program
selected by the Unit holder. Since the Sponsor has arranged for different
reinvestment alternatives, Unit holders should contact the Sponsor for more
complete information, including charges and expenses. The appropriate
prospectus will be sent to the Unit holder. The Unit holder should read the
prospectus for a reinvestment program carefully before deciding to participate.
Participation in the reinvestment program will apply to all Units of a Trust
owned by a Unit holder and may be terminated at any time by the Unit holder, or
the program may be modified or terminated by the Trustee or the program's
Sponsor.
 
SPONSOR'S AND UNDERWRITERS' PROFITS
 
  For their services the Underwriters (see Part A, "Underwriting") receive a
commission based on the sales charge of a particular Trust (see "Public
Offering--Offering Price") as adjusted pursuant to the Agreement Among
Underwriters. The Sponsor receives a gross commission equal to the applicable
sales charge for any Units they have underwritten, and receive the difference
between the applicable sales charge and the Underwriter's commission for the
remainder of the Units. In addition, the Sponsor may realize profits or sustain
losses, as the case may be, in the amount of any difference between the cost of
the Bonds to a Trust (which is based on the aggregate offering price of the
underlying Bonds on the Date of Deposit) and the purchase price of such Bonds
to the Sponsor (which is the cost of the Bonds at the time they were acquired
for the account of a Trust and the cost of the Deposited Units at the time they
were acquired by the Sponsor). (See Part A, "Portfolio of Securities"--Note
(3).) Under certain circumstances, an Underwriter may be entitled to share in
such profits, if any, realized by the Sponsor. The Sponsor may also realize
profits or sustain losses with respect to Bonds deposited in a Trust which were
acquired from its own organization or from underwriting syndicates of which it
was a member. During the initial public offering period the Underwriters also
may realize profits or sustain losses as a result of fluctuations after the
Date of
 
                                      B-17
<PAGE>
 
Deposit in the offering prices of the Bonds and hence in the Public Offering
Price received by the Underwriters for Units. Cash, if any, made available to
the Sponsor prior to the anticipated first settlement date for the purchase of
Units may be used in the Sponsor's businesses to the extent permitted by
applicable regulations and may be of use to the Sponsor.
 
  In maintaining a market for the Units of a Trust (see "Public Offering--
Market for Units"), the Sponsor will also realize profits or sustain losses in
the amount of any difference between the price at which they buy such Units and
the price at which they resell or redeem such Units (see "Public Offering--
Offering Price").
 
RIGHTS OF UNIT HOLDERS
 
CERTIFICATES
 
  Ownership of Units of a Trust is evidenced by registered certificates
executed by the Trustee and the Sponsor. Certificates are transferable by
presentation and surrender to the Trustee properly endorsed or 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
 
  Interest and principal received by a Trust will be distributed on each
monthly Distribution Date on a pro rata basis to Unit holders in such Trust of
record as of the preceding Record Date. All distributions will be net of
applicable expenses and funds required for the redemption of Units and, if
applicable, reimbursements to the Trustee for interest payments advanced to
Unit holders on previous Monthly Distribution Dates. (See Part A, "Summary of
Essential Information," "Tax Exempt Securities Trust--Expenses and Charges" and
"Rights of Unit Holders--Redemption of Units.")
 
  The Trustee will credit to the Interest Account of a Trust all interest
received by such Trust, including that part of the proceeds of any disposition
of Bonds of such Trust which represents accrued interest. Other receipts will
be credited to the Principal Account of a Trust. The pro rata share of the
Interest Account and the pro rata share of cash in the Principal Account
represented by each Unit of a Trust will be computed by the Trustee each month
as of the Record Date. (See Part A, "Summary of Essential Information.")
Proceeds received from the disposition of any of the Bonds subsequent to a
Record Date and prior to the next succeeding Distribution Date will be held in
the Principal Account and will not be distributed until the following
Distribution Date. The distribution to the Unit holders as of each Record Date
will be made on the following Distribution Date or shortly thereafter and shall
consist of an amount substantially equal to one-twelfth of such holders' pro
rata share of the estimated annual income to the Interest Account after
deducting estimated expenses (the "Monthly Income Distribution") plus such Unit
holders' pro rata share of the cash balance in the Principal Account computed
as of the close of business on the preceding 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.
No distribution need be made from the Principal Account if the balance therein
is less than an amount sufficient to distribute $5.00 per Unit. The Monthly
Income Distribution per Unit initially will be in the amount shown under Part
A, "Summary of Essential Information" for a Trust and will change as the income
and expenses of such Trust change and as Bonds are exchanged, redeemed, paid or
sold.
 
  Normally, interest on the Bonds in the Portfolio of a Trust is paid on a
semi-annual basis. Because Bond interest is not received by a Trust at a
constant rate throughout the year, any Monthly Income Distribution may be more
or less than the amount credited to the Interest Account as of the Record Date.
In order to eliminate fluctuations in Monthly Income Distributions resulting
from such variances, the Trustee is required by the Trust Agreement to advance
such amounts as may be necessary to provide Monthly Income Distributions of
approximately equal amounts. The Trustee will be reimbursed, without interest,
for any such advances from funds available from the Interest Account on the
next ensuing Record Date or Record Dates, as the case may be. If all or a
portion of the Bonds for which advances have been made subsequently fail to pay
interest when due, the Trustee may recoup advances made by it in anticipation
of receipt of interest payments on such Bonds by reducing the amount
distributed per Unit in one or more Monthly Interest Distributions. If Units
are redeemed subsequent to such advances by the Trustee, but prior to receipt
by the Trustee of actual notice of such failure to pay interest, the amount of
which was so advanced by the Trustee, each remaining Unit holder will be
subject to a greater pro rata reduction in his Monthly Interest Distribution
than would have occurred absent such redemptions. Funds which are available for
future distributions, payments of expenses and redemptions are in accounts
which are non-interest bearing to Unit holders and are available for use by The
Chase Manhattan Bank pursuant to normal banking procedures. The Trustee is
entitled to the benefit of any reasonable cash balances in the Income and
Principal Accounts. Because of the varying interest payment dates of the Bonds
comprising a Trust Portfolio, accrued interest at any point in time will be
greater than the amount of interest actually received by a Trust and
distributed to Unit holders. This
 
                                      B-18
<PAGE>
 
excess accrued but undistributed interest amount will be added to the value of
the Units on any purchase made after the Date of Deposit. If a Unit holder
sells all or a portion of his Units a portion of his sale proceeds will be
allocable to his proportionate share of the accrued interest. Similarly, if a
Unit holder redeems all or a portion of his Units, the Redemption Price per
Unit which he is entitled to receive from the Trustee will also include his
accrued interest on the Bonds. (See "Rights of Unit Holders--Redemption of
Units--Computation of Redemption Price per Unit.") The Trustee is also entitled
to withdraw from the Interest Account, and to the extent funds are not
sufficient therein, from the Principal Account, on one or more Record Dates as
may be appropriate, amounts sufficient to recoup advances which it has made in
anticipation of the receipt by the Trust of interest in respect of Bonds which
subsequently fail to pay interest when due.
 
  As of the first day of each month the Trustee will deduct from the Interest
Account of a Trust and, to the extent funds are not sufficient therein, from
the Principal Account of such Trust, amounts necessary to pay the expenses of
such Trust. (See "Tax Exempt Securities 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 a
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 of Units.")
 
  The Trustee has agreed to advance to a Trust the amount of accrued interest
due on the Bonds of such Trust from their respective issue dates or previous
interest payment dates through the Date of Deposit. This accrued interest
amount will be paid to the Sponsor as the holder of record of all Units on the
first settlement date for the Units. Consequently, when the Sponsor sells Units
of a Trust, the amount of accrued interest to be added to the Public Offering
Price of the Units purchased by an investor will include only accrued interest
from the day after the Date of Deposit through the date of settlement of the
investor's purchase (normally three business days after purchase), less any
distributions from the Interest Account. The Trustee will recover its
advancements to a Trust (without interest or other cost to such Trust) from
interest received on the Bonds deposited in such Trust.
 
REPORTS AND RECORDS
 
  The Trustee shall furnish Unit holders 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. In the event that the issuer of any of the Bonds fails to make
payment when due of any interest or principal and such failure results in a
change in the amount which would otherwise be distributed as a monthly
distribution, the Trustee will, with the first such distribution following such
failure, set forth in an accompanying statement, the issuer and the Bond, the
amount of the reduction in the distribution per Unit resulting from such
failure, the percentage of the aggregate principal amount of Bonds which such
Bond represents and, to the extent then determined, information regarding any
disposition or legal action with respect to such Bond. 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 (1) as to the Interest Account: interest received (including amounts
representing interest received upon any disposition of Bonds), deductions for
payment of applicable taxes and for fees and expenses of a Trust, 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
Bonds and the net proceeds received therefrom (excluding any portion
representing interest), deductions for payments of applicable taxes and for
fees and expenses of a Trust, 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; (3) a list of the
Bonds 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 accounts of a Trust shall be audited not less frequently than annually by
independent auditors designated by the Sponsor, and the report of such auditors
shall be furnished by the Trustee to Unit holders upon request.
 
  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 Bonds in the
Portfolio of a Trust and a copy of the Trust Agreement.
 
REDEMPTION OF UNITS
 
  Units may be tendered to the Trustee for redemption at its unit investment
trust office at 4 New York Plaza, New York, New York 10004, upon payment of any
relevant 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 Sponsor or
the Trustee. Units redeemed by the Trustee will be cancelled.
 
 
                                      B-19
<PAGE>
 
  Certificates for Units to be redeemed must be properly endorsed or
accompanied by a written instrument of transfer. Unit holders must sign exactly
as their name appears on the face of the certificate with the signature
guaranteed by an officer of a national bank or trust company or by a member of
either the New York, Midwest or Pacific Stock Exchange. 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.
 
  Within seven calendar days 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 the
"Summary of Essential Information" in Part A on the date of tender. (See
"Redemption of Units--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 as regards Units received after the close of trading on the New York
Stock Exchange, the date of tender is the next day on which such Exchange is
open for trading, 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 Sponsor of Units tendered
to the Trustee for redemption at prices in excess of the Redemption Price, see
"Redemption of Units--Purchase by the Sponsor 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 Bonds in order to make
funds available for redemption. Such sales, if required, could result in a sale
of Bonds by the Trustee at a loss. To the extent Bonds are sold, the size and
diversity of a Trust will be reduced.
 
  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 trading on that Exchange is restricted or during which (as
determined by the Securities and Exchange Commission) an emergency exists as a
result of which disposal or evaluation of the underlying Bonds is not
reasonably practicable, or for such other periods as the Securities and
Exchange Commission has by order permitted.
 
  COMPUTATION OF REDEMPTION PRICE PER UNIT--The Redemption Price per Unit of a
Trust is determined by the Trustee on the basis of the bid prices of the Bonds
in such Trust as of the Evaluation Time on the date any such determination is
made. The Redemption Price per Unit of a Trust is each Unit's pro rata share,
determined by the Trustee, of: (1) the aggregate value of the Bonds in such
Trust on the bid side of the market (determined by the Evaluator as set forth
below), (2) cash on hand in such Trust (other than funds covering contracts to
purchase Bonds), and accrued and unpaid interest on the Bonds as of the date of
computation, less (a) amounts representing taxes or governmental charges
payable out of such Trust, (b) the accrued expenses of such Trust, and (c) cash
held for distribution to Unit holders of such Trust of record as of a date
prior to the evaluation. The Evaluator may determine the value of the Bonds in
the Trust (1) on the basis of current bid prices for the Bonds, (2) if bid
prices are not available for any Bonds, on the basis of current bid prices for
comparable securities, (3) by appraisal, or (4) by any combination of the
above.
 
  The difference between the bid and offering prices of the Bonds may be
expected to average approximately 1 1/2% of principal amount. In the case of
actively traded securities, the difference may be as little as 1/2 of 1%, and
in the case of inactively traded securities such difference usually will not
exceed 3%. The price at which Units may be redeemed could be less than the
price paid by the Unit holder. On the Date of Deposit for each Trust the
aggregate current offering price of such Bonds per Unit exceeded the bid price
of such Bonds per Unit by the amounts set forth under Part A, "Summary of
Essential Information."
 
  PURCHASE BY THE SPONSOR OF UNITS TENDERED FOR REDEMPTION--The Trust Agreement
requires that the Trustee notify the Sponsor of any tender of Units for
redemption. So long as the Sponsor maintains a bid in the secondary market, the
Sponsor, 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 not later than the day on which the Units would otherwise
have been redeemed by the Trustee. (See "Public Offering--Market for Units.")
 
  The offering price of any Units resold by the Sponsor 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 Sponsor which likewise will bear any loss
resulting from a lower offering or redemption price subsequent to their
acquisition of such Units. (See "Public Offering--Sponsor's and Underwriters'
Profits.")
 
SPONSOR
 
  Smith Barney Inc., 388 Greenwich Street, New York, New York 10013 ("Smith
Barney"), was incorporated in Delaware in 1960 and traces its history through
predecessor partnerships to 1873. Smith Barney, an investment banking and
securities broker-dealer firm, is a member of the New York Stock Exchange, Inc.

  Smith Barney or an affiliate is investment adviser, principal underwriter or
distributor of 60 open-end investment companies and investment manager of 12
closed-end investment companies. Smith Barney also sponsors all Series of
Corporate Securities Trust, Government Securities Trust, Harris, Upham Tax-

member of various underwriting and selling groups or as agent of other
investment companies, the Sponsor also executes orders for the purchase and
sale of securities of investment companies and sells securities to such
companies in its capacity as broker or dealer in securities.
 
LIMITATIONS ON LIABILITY
 
  The Sponsor is liable for the performance of its obligations arising from its
responsibilities under the Trust Agreement, but will be under no liability to
Unit holders for taking any action or refraining from any action in good faith
or for errors in judgment or responsible in any way for depreciation or loss
incurred by reason of the sale of any Bonds, except in cases of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations and duties. (See "Sponsor--Responsibility" below.)
 
RESPONSIBILITY
 
  Although the Trusts are not actively managed as mutual funds are, the
portfolios are reviewed periodically on a regular cycle. The Sponsor is
empowered to direct the Trustee to dispose of Bonds when certain events occur
that adversely affect the value of the Bonds, including default in payment of
interest or principal, default in payment of interest or principal on other
obligations of the same issuer, institution of legal proceedings, default under
other documents adversely affecting debt service, decline in price or the
occurrence of other market or credit factors, or decline in projected income
pledged for debt service on revenue Bonds and advanced refunding that, in the
opinion of the Sponsor, may be detrimental to the interests of the Unit
holders.
 
  The Sponsor intends to provide Portfolio supervisory services for each Trust
in order to determine whether the Trustee should be directed to dispose of any
such Bonds.
 
  It is the responsibility of the Sponsor to instruct the Trustee to reject any
offer made by an issuer of any of the Bonds to issue new obligations in
exchange and substitution for any Bonds pursuant to a refunding or refinancing
plan, except that the Sponsor may instruct the Trustee to accept such an offer
or to take any other action with respect thereto as the Sponsor may deem proper
if the issuer is in default with respect to such Bonds or in the judgment of
the Sponsor the issuer will probably default in respect to such Bonds 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 Bonds originally deposited thereunder. Within five days after the
deposit of obligations in exchange or substitution for underlying Bonds, the
Trustee is required to give notice thereof to each Unit holder, identifying the
Bonds eliminated and the Bonds substituted therefor. Except as stated in this
and the preceding paragraph, the acquisition by a Trust of any securities other
than the Bonds initially deposited in the Trust is prohibited.
 
RESIGNATION
 
  If the Sponsor resigns or otherwise fails or becomes unable to perform its
duties under the Trust Agreement, and no express provision is made for action
by the Trustee in such event, the Trustee may appoint a successor sponsor or
terminate the Trust Agreement and liquidate the Trusts.
 
TRUSTEE
 
  The Trustee is The Chase Manhattan Bank with its principal executive office
located at 270 Park Avenue, New York, New York 10017 and its unit investment
trust office at 4 New York Plaza, New York, New York 10004. The Trustee is
subject to supervision by the Superintendent of Banks of the State of New York,
the Federal Deposit Insurance Corporation and the Board of Governors of the
Federal Reserve System. In connection with the storage and handling of certain
Bonds deposited in the Trust, the Trustee may use the services of The
Depository Trust Company. These services may include safekeeping of the Bonds
and coupon-clipping, computer book-entry transfer and institutional delivery
services. The Depository Trust Company is a limited purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System and a clearing agency registered under the Securities
Exchange Act of 1934.
 
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
willful misfeasance, bad faith, gross negligence or reckless disregard for its
obligations and duties. In
 
                                      B-21
<PAGE>
 
addition, the Trustee shall not be personally liable for any taxes or other
governmental charges imposed upon or in respect of a 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 "Tax Exempt Securities Trust--
Portfolio.") For information relating to the responsibilities and
indemnification of the Trustee under the Trust Agreement, reference is made to
the material set forth under "Rights of Unit Holders", "Sponsor--Resignation"
and "Other Charges."
 
RESIGNATION
 
  By executing an instrument in writing and filing the same with the Sponsor,
the Trustee and any successor may resign. In such an event the Sponsor is
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, the Sponsor 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 no successor has accepted the appointment within thirty days after notice of
resignation, 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.
 
EVALUATOR
 
  The Evaluator is Kenny S&P Evaluation Services, a business unit of J.J. Kenny
Company, Inc., a subsidiary of The McGraw-Hill Companies, Inc., with main
offices located at 65 Broadway, New York, New York 10006.
 
LIMITATIONS ON LIABILITY
 
  The Trustee, Sponsor and Unit holders may rely on any evaluation furnished by
the Evaluator and shall have no responsibility for the accuracy thereof.
Determination 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
Sponsor, or Unit holders for errors in judgment. But this provision shall not
protect the Evaluator in cases of willful misfeasance, bad faith, gross
negligence or reckless disregard of its obligations and duties.
 
RESPONSIBILITY
 
  The Trust Agreement requires the Evaluator to evaluate the Bonds of a Trust
on the basis of their bid prices on the last business day of June and December
in each year, on the day on which any Unit of such Trust is tendered for
redemption and on any other day such evaluation is desired by the Trustee or is
requested by the Sponsor. For information relating to the responsibility of the
Evaluator to evaluate the Bonds on the basis of their offering prices, see
"Public Offering--Offering Price."
 
RESIGNATION
 
  The Evaluator may resign or may be removed by the joint action of the Sponsor
and the Trustee, and in such event, the Sponsor 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 a
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
 
AMENDMENT
 
  The Sponsor 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 interests of the Unit holders; provided, that the Trust Agreement is
not 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 a Trust, except for
the substitution of certain refunding securities for such Bonds or to permit
the Trustee to engage in business or investment activities not specifically
authorized in the Trust Agreement as originally adopted. In the event of any
amendment, the Trustee is obligated to notify promptly all Unit holders of the
substance of such amendment.
 
                                      B-22
<PAGE>
 
TERMINATION
 
  The Trust Agreement provides that if the principal amount of Bonds held in
Trust is less than 50% of the principal amount of the Bonds originally
deposited in such Trust, the Trustee may in its discretion and will, when
directed by the Sponsor, terminate such Trust. A Trust may be terminated at any
time by 100% of the Unit holders. However, in no event may a Trust continue
beyond the Mandatory Termination Date set forth under Part A, "Summary of
Essential Information." 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 Bonds remaining in the affected
Trust, and, after paying all expenses and charges incurred by such Trust, will
distribute to each Unit holder, upon surrender for cancellation of his
certificate for Units, his pro rata share of the balances remaining in the
Interest and Principal Account of such Trust.
 
LEGAL OPINION
 
  The legality of the Units has been passed upon by Battle Fowler LLP, 75 East
55th Street, New York, New York 10022, as special counsel for the Sponsor.
 
AUDITORS
 
  The statements of financial condition and the portfolios of securities
included in this Prospectus have been audited by KPMG Peat Marwick LLP,
independent auditors, as indicated in their report with respect thereto, and is
included herein in reliance upon the authority of said firm as experts in
accounting and auditing.
 
BOND RATINGS+
 
  All ratings shown under Part A, "Portfolio of Securities", except those
identified otherwise, are by Standard & Poor's.
 
STANDARD & POOR'S
 
  A Standard & Poor's corporate or municipal bond rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
debt 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 or sell 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. The ratings may be changed, suspended or withdrawn as a result of
changes in, or unavailability of, such information.
 
  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; and
 
    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--This is the highest rating assigned by Standard & Poor's to a debt
obligation and indicates an extremely strong capacity to pay interest and repay
principal.
 
  AA--Bonds rated AA have a very strong capacity to pay interest and repay
principal, and in the majority of instances they differ from AAA issues only in
small degrees.
 
  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 weakened capacity to pay interest and repay principal for
bonds in this category than for bonds in the higher-rated categories.
 
  Plus (+) or Minus (-): To provide more detailed indications of credit
quality, the ratings from "AA" to "BB" may be modified by the addition of a
plus or minus sign to show relative standing within the major rating
categories.
 
  Provisional Ratings: The letter "p" following a rating indicates the rating
is provisional. A provisional rating assumes the successful completion of the
project being financed by the issuance of the bonds being rated and indicates
that payment of debt service requirements
- -------
+As described by the rating agencies.
 
                                      B-23
<PAGE>
 
is largely or entirely dependent upon the successful and timely completion of
the project. This rating, however, while addressing credit quality subsequent
to completion, makes no comment on the likelihood of, or the risk of default
upon failure of, such completion. Accordingly, the investor should exercise his
own judgment with respect to such likelihood and risk.
 
  Conditional rating(s), indicated by "Con" are given to bonds for which the
continuance of the security rating is contingent upon Standard & Poor's receipt
of an executed copy of the escrow agreement or closing documentation confirming
investments and cash flows and/or the security rating is conditional upon the
issuance of insurance by the respective insurance company.
 
MOODY'S
 
  A brief description of the applicable Moody's rating symbols and their
meanings is as follows:
 
  Aaa--Bonds which are rated Aaa are judged to be of 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. Aa bonds 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.
 
  Rating symbols may include numerical modifiers "1," "2," or "3." The
numerical modifier "1" indicates that the security ranks at the high end, "2"
in the mid-range, and "3" nearer the low end of the generic category. These
modifiers of rating symbols "Aa," "A" and "Baa" are to give investors a more
precise indication of relative debt quality in each of the historically defined
categories.
 
FITCH
 
  AAA--These bonds are considered to be investment grade and of the highest
quality. The obligor has an extraordinary ability to pay interest and repay
principal, which is unlikely to be affected by reasonably foreseeable events.
 
  AA--These bonds are considered to be investment grade and of high quality.
The obligor's ability to pay interest and repay principal, while very strong,
is somewhat less than for AAA rated securities or more subject to possible
change over the term of the issue.
 
  A--These bonds are considered to be investment grade and of good quality. The
obligor's ability to pay interest and repay principal is considered to be
strong, but may be more vulnerable to adverse changes in economic conditions
and circumstances than bonds with higher ratings.
 
  BBB--These bonds are considered to be investment grade and of satisfactory
quality. The obligor's ability to pay interest and repay principal is
considered to be adequate. Adverse changes in economic conditions and
circumstances, however are more likely to weaken this ability than bonds with
higher ratings.
 
  A "+" or a "-" sign after a rating symbol indicates relative standing in its
rating.
 
DUFF & PHELPS
 
  AAA--Highest credit quality. The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.
 
  AA--High credit quality. Protection factors are strong. Risk is modest but
may vary slightly from time to time because of economic conditions.
 
  A--Protection factors are average but adequate. However, risk factors are
more variable and greater in periods of economic stress.
 
  A "+" or a "-" sign after a rating symbol indicates relative standing in its
rating.
 
                                      B-24

FEDERAL TAX FREE VS. TAXABLE INCOME
 
  This table shows the approximate yields which taxable securities must earn in
various income brackets to produce, after Federal income tax, returns
equivalent to specified tax-exempt bond yields. The table is computed on the
theory that the taxpayer's highest bracket tax rate is applicable to the entire
amount of any increase or decrease in his taxable income resulting from a
switch from taxable to tax-exempt securities or vice versa. The table reflects
projected Federal income tax rates and the tax brackets for the 1997 taxable
year. Because the Federal rate brackets are subject to adjustment based on
changes in the Consumer Price Index, the taxable equivalent yields for
subsequent years may vary somewhat from those indicated in the table. Use this
table to find your tax bracket. Read across to determine the approximate
taxable yield you would need to equal a return free of Federal income tax.

</TABLE>
 
 
Note: This table reflects the following:
  1 Taxable income, as reflected in the above table, equals Federal adjusted
    gross income (AGI), less personal exemptions and itemized deductions.
    However, certain itemized deductions are reduced by the lesser of (i)
    three percent of the amount of the taxpayer's AGI over $121,200, or (ii)
    80 percent of the amount of such itemized deductions otherwise allowable.
    The effect of the three percent phase out on all itemized deductions and
    not just those deductions subject to the phase out is reflected above in
    the combined Federal and state tax rates through the use of higher
    effective Federal tax rates. In addition, the effect of the 80 percent
    cap on overall itemized deductions is not reflected on this table.
    Federal income tax rules also provide that personal exemptions are phased
    out at a rate of two percent for each $2,500 (or fraction thereof) of AGI
    in excess of $181,800 for married taxpayers filing a joint tax return and
    $121,200 for single taxpayers. The effect of the phase out of personal
    exemptions is not reflected in the above table.
  2 Interest earned on municipal obligations may be subject to the federal
    alternative minimum tax. This provision is not incorporated into the
    table.
  3 The taxable equivalent yield table does not incorporate the effect of
    graduated rate structures in determining yields. Instead, the tax rates
    used are the highest marginal tax rates applicable to the income levels

  4 Interest earned on all municipal obligations may cause certain investors
    to be subject to tax on a portion of their Social Security and/or
    railroad retirement benefits. The effect of this provision is not
    included in the above table.
 
PERFORMANCE INFORMATION
 
  Sales material may compare tax-equivalent yields of long-term municipal bonds
to long-term U.S. Treasury bonds and to the Bond Buyer Revenue Bond Index. Such
information is based on past performance and is not indicative of future
results. Yields on taxable investment are generally higher than those of tax-
exempt securities of comparable maturity. While income from municipal bonds is
exempt from federal income taxes, income from Treasuries is exempt from state
and local taxes. Since Treasuries are considered to have the highest possible
credit quality, the difference in yields is somewhat narrower than if compared
to corporate bonds with similar ratings and maturities.

TAX EXEMPT SECURITIES TRUST--THE STATE TRUSTS
 
  Potential purchasers of the Units of a State Trust should consider the fact
that the Trust's Portfolio consists primarily of Bonds issued by the state for
which such State Trust is named or its municipalities or authorities and
realize the substantial risks associated with an investment in such Bonds. Each
State Trust is subject to certain additional risk factors. The Sponsor believes
the discussions of risk factors summarized below describe some of the more
significant aspects of the State Trusts. The sources of such information are
the official statements of issuers as well as other publicly available
documents. While the Sponsor has not independently verified this information,
it has no reason to believe that such information is not correct in all
material respects. Investment in a State Trust should be made with an
understanding that the value of the underlying Portfolio may decline with
increases in interest rates.
 
MARYLAND TRUST
 
  RISK FACTORS--The Public indebtedness of the State of Maryland (the "State")
and its instrumentalities is divided into three general types. The State issues
general obligation bonds for capital improvements and for various State
projects to the payment of which the State ad valorem property tax is
exclusively pledged. In addition, the Maryland Department of Transportation
issues for transportation purposes its limited, special obligation bonds
payable primarily from specific, fixed-rate excise taxes and other revenues
related mainly to highway use. Certain authorities issue obligations payable
solely from specific non-tax, enterprise fund revenues and for which the State
has no liability and has given no moral obligation assurance.
 
  General obligation bonds of the State are authorized and issued primarily to
provide funds for State-owned capital improvements, including institutions of
higher learning, and the construction of locally owned public schools. Bonds
have also been issued for local government improvements, including grants and
loans for water quality improvement projects and correctional facilities, to
provide funds for repayable loans or outright grants to private, non-profit
cultural or educational institutions, and to fund certain loan and grant
programs.
 
  The Maryland Constitution prohibits the contracting of State debt unless it
is authorized by a law levying an annual tax or taxes sufficient to pay the
debt service within 15 years and prohibiting the repeal of the tax or taxes or
their use for another purpose until the debt is paid. As a uniform practice,
each separate enabling act which authorizes the issuance of general obligation
bonds for a given object or purpose has specifically levied and directed the
collection of an ad valorem property tax on all taxable property in the State.
The Board of Public Works is directed by law to fix by May 1 of each year the
precise rate of such tax necessary to produce revenue sufficient for debt
services requirements of the next fiscal year, which begins July 1. However,
the taxes levied need not be collected if or to the extent that funds
sufficient for debt services requirements in the next fiscal year have been
appropriated in the annual State budget. Accordingly, the Board in annually
fixing the rate of property tax after the end of the regular legislative
session in April, takes account of appropriations of general funds for debt
service.
 
  In the opinion of counsel, the courts of Maryland have jurisdiction to
entertain proceeds and power to grant mandatory injunctive relief to (i)
require the Governor to include in the annual budget a sufficient appropriation
to pay all general obligation bond debt service for the ensuing fiscal year;
(ii) prohibit the General Assembly from taking action to reduce any such
appropriation below the level required for that debt service; (iii) require the
Board of Public Works to fix and collect a tax on all property in the State
subject to assessment for State tax purposes at a rate and in an amount
sufficient to make such payments to the extent that adequate funds are not
provided in the annual budget; and (iv) provide such other relief as might be
necessary to enforce the collection of such taxes and payment of the proceeds
of the tax collection to the holders of general obligation bonds, pari passu,
subject to the inherent constitutional limitations referred to below.
 
  It is also the opinion of counsel that, while the mandatory injunctive
remedies would be available and while the general obligation bonds of the State
are entitled to constitutional protection against the impairment of the
obligation of contracts, such constitutional protection and the enforcement of
such remedies would not be absolute. Enforcement of a claim for payment of the
principal of or interest on the bonds would be subject to the provisions of any
statutes that may be constitutionally enacted by the United States Congress or
the Maryland General Assembly extending the time for payment or imposing other
constraints upon enforcement.
 
  There is no general debt limit imposed by the Maryland Constitution or public
general laws, but a special committee created by statute annually submits to
the Governor an estimate of the maximum amount of new general obligation debt
that prudently may be authorized. Although the committee's responsibilities are
advisory only, the Governor is required to give due consideration to the
committee's findings in preparing a preliminary allocation of new general debt
authorization for the next ensuing fiscal year.

  Consolidated Transportation Bonds are limited obligations issued by the
Maryland Department of Transportation, the principal of which must be paid
within 15 year from the date of issue, for highway, port, transit, rail or
aviation facilities or any combination of such facilities. Debt service on
Consolidated Transportation Bonds is payable from those portions of the excise
tax on each gallon of motor vehicle fuel and the motor vehicle titling tax, all
mandatory motor vehicle registration fees, monitor carrier fees, and the
corporate income tax as are credited to the Maryland Department of
Transportation, plus all departmental operating revenues and receipts. Holders
of such bonds are not entitled to look to other sources for payment.
 
  The Maryland Department of Transportation also issues its bonds to provide
financing of local road construction and various other county transportation
projects and facilities. Debt service on these bonds is payable from the
subdivisions' share of highway user revenues held to their credit in a special
State fund. On November 9, 1994, the Maryland Transportation Authority issued
$162.6 million of special obligation revenue bonds to fund projects at the
Baltimore/Washington International Airport secured by revenues from the
passenger facility charges received by the Maryland Aviation Administration and
from the general account balance of the Transportation Authority. As of June
30, 1997, $388.7 million of the Transportation Authority's revenue bonds were
outstanding.
 
  The Maryland Transportation Authority operates certain highway, bridge and
tunnel toll facilities in the State. The tolls and other revenues received from
these facilities are pledged as security for revenue bonds of the Authority
issued under and secured by a trust agreement between the Authority and a
corporate trustee.
 
  Certain other instrumentalities of the State government are authorized to
borrow money under legislation which expressly provides that the loan
obligations shall not be deemed to constitute a debt or a pledge of the faith
and credit of the State. The Community Development Administration of the
Department of Housing and Community development, the Board of Trustees of St.
Mary's College of Maryland, the Maryland Environmental Service, the Board of
Regents of the University of Maryland System, the Board of Regents of Morgan
State University, and the Maryland Food Center Authority have issued and have
outstanding bonds of this type. The principal of and interest on bonds issued
by these bodies are payable solely from various sources, principally fees
generated from use of the facilities or enterprises financed by the bonds.
 
  Under a Comprehensive Plan of Financing, as amended, of the Maryland Stadium
Authority, the Authority is authorized to finance the acquisition and
construction of sports facilities at a site within the City of Baltimore.
Currently, the Stadium Authority operates Oriole Park at Camden Yards which
opened in 1992. The Authority's financings are lease-backed revenue
obligations, payment of which is secured by, among other things, an assignment
of revenues to be received under a lease of the sports facilities from the
Authority to the State of Maryland; rental payments due from the State under
that lease will be subject to annual appropriation by the Maryland General
Assembly.
 
  In October 1995, the Stadium Authority and the Baltimore Ravens (formally
known as the Cleveland Browns) executed a Memorandum of Agreement which commits
the Ravens to occupy a to be constructed football stadium in Baltimore City.
The Agreement was approved by the Board of Public Works and constitutes a
"long-term lease with a National Football League team" as required by statute
for the issuance of Stadium Authority bonds. The Stadium Authority sold $87.565
million in lease-backed revenue bonds on May 1, 1996. The proceeds form the
bonds, along with cash available from State lottery proceeds, investment
earnings, and other sources will be used to pay project design and construction
expenses of approximately $200 million. The bonds are solely secured by an
assignment of revenues received under a lease of the project from the Stadium
Authority to the State.
 
  The Stadium Authority has also been assigned responsibility for constructing
an expansion of the Convention Centers in Baltimore City and Ocean City and
construction of a conference center in Montgomery County. The Baltimore
Convention Center expansion is expected to cost $163 million and is being
financed through a combination of funding from Baltimore City, Stadium
Authority revenue bonds, and State general obligation bonds. The Ocean City
Convention Center expansion is expected to cost $35 million and is being
financed through a combination of funding from Ocean City and the Stadium
Authority. The Montgomery County Conference Center is expected to cost $27.5
million and is being financed through a combination of funding from Montgomery
County and the Stadium Authority.
 
  The Water Quality Revolving Loan Fund is administered by the Water Quality
Financing Administration in the Department of the Environment. The Fund may be
used to provide loans, subsidies and other forms of financial assistance to
local government units for wastewater treatment projects as contemplated by the
1987 amendments to the federal Water Pollution Control Act. The Administration
is authorized to issue bonds secured by revenues of the Fund, including loan
repayments, federal capitalization grants, and matching State grants.

  The University of Maryland System, Morgan State University, and St. Mary's
College of Maryland are authorized to issue revenue bonds for the purpose of
financing academic and auxiliary facilities. Auxiliary facilities are any
facilities that furnish a service to students, faculty, or staff, and that
generate income. Auxiliary facilities include housing, eating, recreational,
campus, infirmary, parking, athletic, student union or activity, research
laboratory, testing and any related facilities.
 
  Although the State has authority to make short-term borrowings in
anticipation of taxes and other receipts up to a maximum of $100 million, in
the past it has not issued short-term borrowings. However, the State has issued
certain obligations in the nature of bond anticipation notes for the purpose of
assisting several savings and loan associations in qualifying for Federal
insurance and in connection with the assumption by a bank of the deposit
liabilities of an insolvent savings and loan association.
 
  The State has financed the construction and acquisition of various facilities
through conditional purchase, sale-leaseback, and similar transactions. All of
the lease payments under these arrangements are subject to annual appropriation
by the Maryland General Assembly. In the event that appropriations are not
made, the State may not be held contractually liable for the payments.
 
  LOCAL SUBDIVISION DEBT. The counties and incorporated municipalities in
Maryland issue general obligation debt for general governmental purposes. The
general obligation debt of the counties and incorporated municipalities is
generally supported by ad valorem taxes on real estate, tangible personal
property and intangible personal property subject to taxation. The issuer
typically pledges its full faith and credit and unlimited taxing power to the
prompt payment of the maturing principal and interest on the general obligation
debt and to the levy and collection of the ad valorem taxes as and when such
taxes become necessary in order to provide sufficient funds to meet the debt
service requirements. The amount of debt which may be authorized may in some
cases be limited by the requirements that it not exceed a stated percentage of
the assessable base upon which taxes are levied.
 
  In the opinion of counsel, the issuer may be sued in the event that it fails
to perform its obligations under the general obligation debt to the holders of
the debt, and any judgments resulting from such suits would be enforceable
against the issuer. Nevertheless, a holder of the debt who has obtained any
such judgment may be required to seek additional relief to compel the issuer to
levy and collect such taxes as may be necessary to provide the Funds from which
a judgment may be paid. Although there is no Maryland law on this point, it is
the opinion of counsel that the appropriate courts of Maryland have
jurisdiction to entertain proceedings and power to grant additional relief,
such as a mandatory injunction, if necessary, to enforce the levy and
collection of such taxes and payment of the proceeds of the collection of the
taxes to the holders of general obligation debt, pari passu subject to the same
constitutional limitations on enforcement, as described above, as apply to the
enforcement of judgments against the State.
 
  Local subdivisions, including counties and municipal corporations, are also
authorized by law to issue special and limited obligation debt for certain
purposes other than general governmental purposes. The source of payment of
that debt is limited to certain revenues of the issuer derived from commercial
activities operated by the issuer, payment made with respect to certain
facilities or loans and any funds pledged for the benefit of the holders of the
debt. That special and limited obligation debt does not constitute a debt of
the State, the issuer or any other political subdivision of either within the
meaning of any constitutional or statutory limitation. Neither the State nor
the issuer or any other political subdivision of either is obligated to pay the
debt or the interest on the debt except from the revenues of the issuer
specifically pledged to the payment of the debt. Neither the faith and credit
nor the taxing power of the State, the issuer or any other political
subdivision of either is pledged to the payment of the debt. The issuance of
the debt is not directly or indirectly or contingently an obligation, moral or
other, of the State, the issuer or any other political subdivision of either to
levy any tax for its payment.
 
  SPECIAL AUTHORITY DEBT. The State and local governments have created several
special authorities with the power to issue debt on behalf of the State or
local government for specific purposes, such as providing facilities for non-
profit health care and higher educational institutions, facilities for the
disposal of solid waste, funds to finance single family and low-to-moderate
income housing, and similar purposes. The Maryland Health and Higher
Educational Facilities Authority, the Northeast Maryland Waste Disposal
Authority, the Housing Opportunities Commission of Montgomery County, and the
Housing Authority of Prince George's County are some of the special authorities
which have issued and have outstanding debt of this type.
 
  The debts of the authorities issuing debt on behalf of the State and the
local governments are limited obligations of the authorities payable solely
from and secured by a pledge of the revenues derived from the facilities or
loans financed with the proceeds of the debt and from any other funds and
receipts pledged under an indenture with a corporate trustee. The debt does not
constitute a debt, liability or pledge of the faith and credit of the State or
of any political subdivision or of the authorities. Neither the State nor any
political subdivision thereof nor the authorities shall be obligated to pay the
debt or the interest on the debt except from such revenues, funds and receipts.
Neither the faith and credit nor the taxing power of the State or of any
political subdivision of the State or the authorities
 
                                      C-3
<PAGE>
 
is pledged to the payment of the principal of or the interest on such debt. The
issuance of the debt is not directly or indirectly an obligation, moral or
other, of the State or of any political subdivision of the State or of the
authority to levy or to pledge any form of taxation whatsoever, or to make any
appropriation, for their payment. The authorities have no taxing power.
 
  MARYLAND TAXES --
 
  In the opinion of Messrs. Weinberg & Green LLC, special Maryland counsel of
Maryland tax matters, under applicable existing Maryland State and local tax
law:
 
    The Maryland Trust will not be treated as an association taxable as a
  corporation, and the income of the Maryland Trust will be treated as the
  income of the Holders. The Maryland Trust is not a "financial institution"
  subject to the Maryland Franchise Tax measure by net earnings. The Maryland
  Trust is not subject to Maryland property taxes imposed on the intangible
  personal property of certain corporations.
 
    Except as described below in the case of interest paid on private
  activity bonds constituting a tax preference for Federal income tax
  purposes, a Holder will not be required to include such Holder's pro-rata
  share of the earnings of, or distributions from, the Maryland Trust in such
  Holder's Maryland taxable income to the extent that such earnings or
  distributions represent interest excludable from gross income for Federal
  income tax purposes received by the Maryland Trust on obligations of the
  State of Maryland, the Government of Puerto Rico, or the Government of Guam
  and their respective political subdivisions and authorities. Subject to a
  three year phase in period (for taxable years beginning after December 31,
  1995 and ending December 31, 1998), interest on Bonds is not subject to the
  Maryland Franchise Tax imposed on "financial institutions" and measured by
  net earnings.
 
    In the case of taxpayers who are individuals, Maryland presently imposes
  an income tax on items of tax preference with reference to such items as
  defined in the Internal Revenue Code, as amended, for purposes of
  calculating the Federal alternative minimum tax. Interest paid on certain
  private activity bonds is a preference item for purposes of calculating the
  Federal alternative minimum tax. Accordingly, if the Maryland Trust holds
  such bonds, 50% of the interest on such bonds in excess of a threshold
  amount is taxable by Maryland.
 
    A Holder will recognize taxable gain or loss, except in the case of an
  individual Holder who is not a Maryland resident, when the Holder disposes
  of all or part of such Holder's pro rata portion of the Bonds in the
  Maryland Trust. A Holder will be considered to have disposed of all or part
  of such Holder's pro rata portion of each Bond when the Holder sells or
  redeems all or some of such Holder's Units. A Holder will also be
  considered to have disposed of all or part of such Holder's pro rata
  portion of a Bond when all or part of the Bond is disposed of by the
  Maryland Trust or is redeemed or paid at maturity. Gains included in the
  gross income of Holders for federal income tax purposes is, however,
  subtracted from income for Maryland income tax purposes to the extent that
  the gain is derived from the disposition of Bonds issued by the State of
  Maryland and its political subdivisions. Subject to a three year phase in
  period, profits realized on the sale or exchange of Bonds are not subject
  to the Maryland Franchise Tax imposed on "financial institutions" and
  measured by net earnings.
 
    Units of the Maryland Trust will be subject to Maryland inheritance and
  estate tax only if held by Maryland residents.
 
    Neither the Bonds nor the Units will be subject to Maryland personal
  property tax.
 
    The sales of Units in Maryland or the holding of Units in Maryland will
  not be subject to Maryland Sales or Use Tax.

TAX FREE VS. TAXABLE INCOME
 
  The following tables show the approximate yields which taxable securities
must earn in various income brackets to equal tax exempt yields under combined
Federal and state individual income tax rates. This table reflects projected
Federal income tax rates and tax brackets for the 1997 taxable year and state
income tax rates that were available on the date of the Prospectus. Because
the Federal rate brackets are subject to adjustment based on changes in the
Consumer Price Index, the taxable equivalent yields for subsequent years may
be lower than indicated. A table is computed on the theory that the taxpayer's
highest bracket tax rate is applicable to the entire amount of any increase or
decrease in taxable income (after allowance for any resulting change in state
income tax) resulting from a switch from taxable to tax-free securities or
vice versa. Variations between state and Federal allowable deductions and
exemptions are generally ignored. The state tax is thus computed by applying
to the Federal taxable income bracket amounts shown in the table the
appropriate state rate for those same dollar amounts. For example, a married
couple living in the State of Maryland and filing a Joint Return with $53,000
in taxable income for the 1997 tax year would need a taxable investment
yielding 8.77% in order to equal a tax-free return of 6.00%. Use the
appropriate table to find your tax bracket. Read across to determine the
approximate taxable yield you would need to equal a return free of Federal
income tax and state income tax.

Note: This table reflects the following:
  1 The above tax rates represent 1997 Federal income tax rates and 1996
    Maryland income tax rates. Maryland has not yet published its 1997
    personal income tax rates.
  2 Maryland counties and the city of Baltimore may levy an income tax which
    is up to 60 percent of the Maryland state income tax. When considered,
    such additional taxes may increase the taxable equivalent yield reflected
    above.
  3 Taxable income, as reflected in the above table, equals Federal adjusted
    gross income (AGI), less personal exemptions and itemized deductions
    (including the deduction for state income tax). However, certain itemized
    deductions are reduced by the lesser of (i) three percent of the amount
    of the taxpayer's AGI over $121,200, or (ii) 80 percent of the amount of
    such itemized deductions otherwise allowable. The effect of the three
    percent phase out on all itemized deductions and not just those
    deductions subject to the phase out is reflected above in the combined
    Federal and state tax rates through the use of higher effective Federal
    tax rates. In addition, the effect of the 80 percent cap on overall
    itemized deductions is not reflected on this table. Federal income tax
    rules also provide that personal exemptions are phased out at a rate of
