TAX EXEMPT SECURITIES TRUST

INVESTMENT SUMMARY AS OF NOVEMBER 30, 1999
Use this Investment Summary to help you decide whether the portfolios
comprising the Tax Exempt Securities Trust are right for you. More detailed
information can be found later in this prospectus.

Investment Objective

Each of the trusts seeks to pay investors monthly distributions of tax exempt
interest income while conserving their capital. The Sponsor has selected a
fixed portfolio of municipal bonds intended to achieve these goals.

Investment Strategy

All of the bonds in each of the trusts are rated A or better by Standard &
Poor's, Moody's or Fitch. State designated trusts primarily contain bonds
issued by the state for which the trust is named or counties, municipalities,
authorities or political subdivisions of that state.

Taxes

Interest on all of the bonds in each of the trusts is generally exempt from
regular Federal income taxes. Interest on all of the bonds in each state trust
is generally exempt from certain state and local personal income taxes of the
state for which the trust is named. Each of the bonds in the trusts received an
opinion from bond counsel rendered on the date of issuance confirming its tax
exempt status.

Risk Factors

Holders can lose money by investing in these trusts. The value of the units and
the bonds held in the portfolio can each decline in value. An investment in
units of a trust should be made with an understanding of the following risks:

  . Municipal bonds are long-term fixed rate debt obligations that decline in
    value with increases in interest rates, an issuer's worsening financial
    condition or a drop in bond ratings.

  . The effective maturity of a long term bond may be dramatically different
    than shorter term obligations. Investors will receive early returns of
    principal when bonds are called or sold before they mature. Investors may
    not be able to reinvest the money they receive at as high a yield or as
    long a maturity.

  . The municipal bonds could lose their tax-exempt status either due to
    future legislation or due to the failure of a public issuer of a bond (or
    private guarantor) to meet certain conditions imposed by various tax
    laws.

  . The default of an issuer of a municipal bond in making its payment
    obligation could result in the loss of interest income and/or principal
    to investors.

  . Since the portfolio of each of the trusts is fixed and not managed, in
    general the Sponsor can only sell bonds at a trust's termination or in
    order to meet redemptions. As a result, the price at which a bond is sold
    may not be the highest price it attained during the life of a trust.

The Public Offering Price

The Public Offering Price per Unit as of November 30, 1999 would have been
$975.25 for the California Trust, $988.51 for the Maryland Trust and $974.97
for the New York Trust. During the initial public offering period the Public
Offering Price per unit is calculated by:

  . dividing the aggregate offering price of the underlying bonds in a trust
    by the number of units outstanding

  . adding a sales charge of 4.70% (4.932% of the aggregate offering price of
    the bonds per unit)

                                      A-2
<PAGE>

  . adding a per unit amount sufficient to reimburse the Sponsor for
    organizational costs

After the initial offering period the Public Offering Price per unit is
calculated by:

  . dividing the aggregate bid price of the underlying bonds in a trust by
    the number of units outstanding

  . adding a sales charge of 5.00% (5.263% of the aggregate bid price of the
    bonds per unit)

Market for Units

The Sponsor currently intends to repurchase units from holders at prices based
upon the aggregate bid price of the underlying bonds. The Sponsor is not
obligated to maintain a market and may stop doing so without prior notice for
any business reason. If the Sponsor stops repurchasing units, a unit holder may
dispose of its units by redemption. The price received from the Trustee by the
unit holder for units being redeemed is also based upon the aggregate bid price
of the underlying bonds. Units can be sold at any time to the Sponsor or the
Trustee without fee or penalty.

*  Accrued interest will commence on the day after the Date of Deposit through
   the date of settlement (normally three business days after purchase).
** This figure will also include accrued interest from the day after the Date
   of Deposit to the date of settlement (normally three business days after
   purchase) and the net cash on hand in the relevant Trust, accrued expenses
   of such Trust and amounts distributable to holders of record of Units of
   such Trust as of a date prior to the computation date, on a pro rata basis.
   As of the close of the initial offering period, the Redemption Price per
   Unit and the Sponsor's Repurchase Price per Unit for each Trust will be
   reduced to reflect the payment of the per Unit organization costs.
*** Per $1,000 principal amount of Bonds, plus expenses.
**** 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.

                          INDEPENDENT AUDITORS' REPORT

To the Sponsor, Trustee and Unit Holders of

 Tax Exempt Securities Trust, California Trust 173, Maryland Trust 110 and New
 York Trust 177:

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, California Trust 173, Maryland Trust 110 and New York
Trust 177 as of November 30, 1999. 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
November 30, 1999, 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, California Trust
173, Maryland Trust 110 and New York Trust 177 as of November 30, 1999, 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 November 30, 1999, 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 $10,000,000 which was deposited with the
    Trustee for the purchase of $9,000,000 principal amount of Bonds in all of
    the Trusts, pursuant to contracts to purchase such Bonds at the aggregate
    cost of $8,367,464 plus $121,024 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) A portion of the Public Offering Price consists of cash in an amount
    sufficient to reimburse the Sponsor for the per Unit portion of all or a
    part of the organization costs of establishing a Trust. These costs have
    been estimated at $2.50 per Unit for each of the Trusts. A payment will be
    made as of the close of the initial public offering period to an account
    maintained by the Trustee from which the obligation of the investors to
    the Sponsor will be satisfied. To the extent that actual organization
    expenses are less than the estimated amount, only the actual organization
    expenses will be deducted from the assets of a Trust.

(4) Aggregate public offering price (exclusive of interest) computed on 3,000
    Units of the California Trust, 2,000 Units of the Maryland Trust and 4,000
    Units of the New York Trust, on the basis set forth in Part B, "Public
    Offering--Offering Price."

(5) Sales charge of 4.70% computed on 3,000 Units of the California Trust,
    2,000 Units of the Maryland Trust and 4,000 Units of the New York Trust 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 (exclusive
    of estimate of organization expense) 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., Moody's Investors Service(*) and Fitch Investor Services, Inc.(**),
    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 October 29,
    1999, through November 30, 1999, with the settlement date on December 3,
    1999. The Profit to the Sponsor on Deposit totals $24,687 for the
    California Trust, $14,485 for the Maryland Trust and $34,563 for the New
    York Trust.

(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 on Date of Deposit was computed on the basis
    of offering prices on the date of deposit. On November 30, 1999, the
    aggregate bid price of the Bonds was $2,769,090 for the California Trust,
    $1,871,337 for the Maryland Trust and $3,691,037 for the New York Trust.

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. A unit investment trust
provides many of the same benefits as individual bond purchases. However, while
receiving many of the benefits, the holder of Units (the "Holder") avoids the
complexity of analyzing, selecting and monitoring a multi-bond portfolio. Each
Trust is also 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 Salomon 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 is referred to herein as the "Trust" and together they are
referred to as "Trusts." 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 (the "Deposited Units"). The
Bonds and Deposited Units (if any) are referred to herein collectively as the
"Securities." After the deposit of the Securities and the creation of the
Trusts, the Trustee delivered to the Sponsor registered certificates of
beneficial interest (the "Certificates") representing the units (the "Units")
comprising the entire ownership of each Trust. These Units are now being
offered hereby. References to multiple Trusts herein should be read as
references to a single Trust if Part A indicates the creation of only one
Trust.

Objectives

  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
no guarantee that a Trust's objectives will be achieved.

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:

  . whether the interest on the Bonds selected would be exempt from Federal
    and/or state income taxes imposed on the Holders;

  . whether the Bonds were rated "A" or better by a major bond rating agency;

  . the maturity dates of the Bonds (including whether such Bonds may be
    called or redeemed prior to their stated maturity);

  . the diversity of the types of Bonds; and

  . the cost of the Bonds relative to what the Sponsor believes is their
    value.

The Units

  Each Unit in a Trust represents a fractional undivided interest in the
principal and net income of such Trust. If any Units are redeemed after the
date of this Prospectus, the principal amount of Bonds in the Trust will be
reduced by an amount allocable to redeemed Units. Also, the fractional
undivided interest in the Trust represented by each unredeemed Unit will be
increased. Units will remain outstanding until redeemed or until the
termination of the Trust.

                                      B-1
<PAGE>

RISK FACTORS

  An investment in Units is subject to the following risks.

Failure of Issuers to Pay Interest and/or Principal

  The primary risk associated with an investment in Bonds is that the issuer of
the Bond will default on principal and/or interest payments when due on the
Bond. Such a default would have the effect of lessening the income generated by
the Trust and/or the value of the Trust's Units. The bond ratings assigned by
major rating organizations are an indication of the issuer's ability to make
interest and principal payments when due on its bonds. Subsequent to the date
of deposit the rating assigned to a bond may decline. Neither the Sponsor nor
the Trustee shall be liable in any way for any default, failure or defect in
any bond.

Original Issue Discount Bonds and Zero Coupon Bonds

  Certain of the Bonds in the Trust may be original issue discount bonds and/or
zero coupon bonds. Original issue discount bonds are bonds originally issued at
less than the market interest rate. Zero coupon bonds are original issue
discount bonds that do not provide for the payment of current interest. For
Federal income tax purposes, original issue discount on such bonds must be
accrued over the terms of such bonds. On sale or redemption, the difference
between (i) the amount realized (other than amounts treated as tax-exempt
income as described below) and (ii) the tax basis of such bonds (properly
adjusted, in the circumstances described below, for the accrual of original
issue discount) will be treated as taxable income, gain or loss. The Code
requires the Trust (and therefore the Unitholders) to accrue tax-exempt
original issue discount by using the constant interest method provided for the
holders of taxable obligations and to increase the basis of a tax-exempt
obligation by the amount of accrued tax-exempt original issue discount. These
provisions are applicable to obligations issued after September 3, 1982 and
acquired after March 1, 1984. The Trust's tax basis in a Bond (and a
Unitholder's tax basis in its Units) is increased by an accrued original issue
discount. For Bonds issued after June 9, 1980 that are redeemed prior to
maturity, the difference between the Trust's basis, as adjusted, and the amount
received will be taxable gain or loss to the Unitholders. All or a portion of
any gain may be taxable as ordinary income.

"When Issued" and "Delayed Delivery" Bonds

  Certain Bonds in a Trust may have been purchased by the Sponsor on a "when
issued" basis. Bonds purchased on a "when issued" basis have not yet been
issued by their governmental entity on the Date of Deposit (although such
governmental entity had committed to issue such Bonds). In the case of these
and/or certain other Bonds, the delivery of the Bonds may be delayed ("delayed
delivery") or may not occur. The effect of a Trust containing "delayed
delivery" or "when issued" Bonds is that Holders who purchased their Units
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. Such downward
adjustment may be necessary to account for interest accruing on such "when
issued" or "delayed delivery" Bonds during the time between their purchase of
Units and delivery of such Bonds. 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 Holders may receive after the first
year. 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.

Redemption or Sale Prior to Maturity

  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

                                      B-2
<PAGE>

provisions. 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. Such price valuation is likely to be higher in periods of declining
interest rates. Certain of the Bonds may be sold or redeemed or otherwise
mature. In such cases, the proceeds from such events will be distributed to
Holders and will not be reinvested. Thus, no assurance can be given that a
Trust will retain for any length of time its present size and composition. To
the extent that a Bond was deposited in a Trust at a price higher than the
price at which it is redeemable, or at a price higher than the price at which
it is sold, a sale or redemption will result in a loss in the value of Units.
Monthly distributions will generally be reduced by the amount of the income
which would otherwise have been paid with respect to sold or redeemed bonds.
The Estimated Current Return and Estimated Long-Term Return of the Units may be
adversely affected by such sales or redemptions.

Market Discount

  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. Bonds selling at market discounts
tend to increase in market value as they approach maturity. A market discount
tax-exempt Bond will have a larger portion of its total return in the form of
taxable ordinary income (because market discount income is taxable ordinary
income) and less in the form of tax-exempt income than a comparable Bond
bearing interest at current market rates. See "Taxes" herein.

Failure of a Contract to Purchase Bonds

  In the event that any contract for the purchase of any Bond fails, the
Sponsor is authorized under the Trust Agreement to instruct the Trustee to
acquire other securities (the "Replacement Bonds") for inclusion in the
Portfolio of the affected Trust. However, in order for the Trustee to acquire
any Replacement Bonds, they must be deposited not later than the earlier of (i)
the first monthly Distribution Date of the Trust or (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:

  . be a tax-exempt bond;

  . have a fixed maturity or disposition date comparable to the Bond it
    replaces;

  . be purchased at a price that results in a yield to maturity and in a
    current return which is approximately equivalent to the yield to maturity
    and current return of the Bond which it replaces;

  . be purchased within twenty days after delivery of notice of the failed
    contracts; and

  . be rated in a category of A or better by a major rating organization.

  Whenever a Replacement Bond has been acquired for a Trust, the Trustee shall,
within five days thereafter, notify all 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 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 Holders not later than the second monthly Distribution
Date. Moreover, the failed contract may reduce the Estimated Net Annual Income
per Unit, and may lower the Estimated Current Return and Estimated Long-Term
Return of the affected Trust.

                                      B-3

Risks Inherent in an Investment in Different Types of Bonds

  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. 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. Some such factors are the entity's tax base, the extent to
which the entity relies on Federal or state aid, and other factors which are
beyond the entity's control.

  Industrial Development Revenue Bonds ("IDRs"). IDRs including pollution
control revenue bonds, are tax-exempt securities issued by states,
municipalities, public authorities or similar entities to finance the cost of
acquiring, constructing or improving various projects. 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. Payment
of IDRs is solely dependent upon the creditworthiness of the corporate operator
of the project or corporate guarantor. Such 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.

  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. Some such factors are
the level of payments received from private third-party payors and government
programs and the cost of providing health care services. There can be no
assurance that payments under governmental programs will remain at levels
comparable to present levels or will be sufficient to cover the costs
associated with their bonds. It also 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 additionally
subject to claims and legal actions by patients and others in the ordinary
course of business. 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.

  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 mortgage loans to
housing projects for low to moderate income families. Single-family mortgage
revenue bonds are issued for the purpose of acquiring notes secured by
mortgages on residences. The ability of housing issuers to make debt service
payments on their obligations may be affected by various economic and non-
economic factors. Such factors include: occupancy levels, 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. 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. Therefore, the average life of housing obligations cannot be
determined. However, the average life of these obligations will ordinarily

                                      B-4
<PAGE>

be less than their stated maturities. Mortgage loans are frequently partially
or completely prepaid prior to their final stated maturities. 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
reduce the amount of income that would otherwise have been paid to Holders.

  Power Facility Bonds. The ability of utilities to meet their obligations with
respect to bonds they issue is dependent on various factors. These factors
include the rates they may charge their customers, the demand for a utility's
services and the cost of providing those services. Utilities are also 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. Utilities are
additionally subject to increased costs due to governmental environmental
regulation and decreased profits due to increasing competition. Any difficulty
in obtaining timely and adequate rate increases could adversely affect a
utility's results of operations. 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.

  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 a number of factors. Some such
factors are the failure of municipalities to utilize fully the facilities
constructed by these authorities, declines in revenue from user charges, rising
construction and maintenance costs, impact of environmental requirements, the
difficulty of obtaining or discovering new supplies of fresh water, the effect
of conservation programs, the impact of "no growth" zoning ordinances and 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. Some of these
factors, of which an investor should be aware, are 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. Also, in the case of public
institutions, the financial condition of the relevant state or other
governmental entity and its policies with respect to education may affect an
institution's ability to make payments on its own.

  Lease Rental Bonds. Lease rental bonds are predominantly issued 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 or the purchase of equipment that will be
used by a state or local government. 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. Lease rental bonds are subject to the
risk that 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 as rental bonds cease
in the event that damage, destruction or condemnation of the project prevents
its use by the lessee. Also, 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.

  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. 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.

                                      B-5
<PAGE>

  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. Also, 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.

  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. Thus, such a commitment 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, highways and port authorities. Airport
operating income may be affected by the ability of airlines to meet their
obligations under the agreements with airports. 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.
The Sponsor cannot predict what effect conditions may have on revenues which
are dependent for payment on these bonds.

  Special Tax Bonds. Special tax bonds are payable from and secured by the
revenues derived by a municipality from a particular tax. Examples of such
special taxes are 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. 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. 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

                                      B-6
<PAGE>

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

Year 2000 Issue

  The Trusts, like other businesses and entities, could be adversely affected
if the computer systems used by the Sponsor and Trustee or other service
providers to a Trust do not properly process and calculate date-related
information and data from and after January 1, 2000. This is commonly known as
the "Year 2000 Problem." The Sponsor and Trustee

                                      B-7
<PAGE>

are taking steps that they believe are reasonably designed to address the Year
2000 Problem with respect to their computer systems. The Sponsor and Trustee
are also seeking to obtain reasonable assurances that comparable steps are
being taken by the Trusts' other service providers. However, there can be no
assurance that the Year 2000 Problem will be properly or timely resolved so to
avoid any adverse impact to each Trust. The Year 2000 Problem may also
adversely affect the issuers of the Bonds contained in the Trust to varying
degrees based upon various factors. The Sponsor is unable to predict what
affect, if any, the Year 2000 Problem will have on such issuers.

Insurance

  Certain Bonds (the "Insured Bonds") may be insured or guaranteed by American
Capital Access Corporation ("ACA"), Asset Guaranty Insurance Co. ("AGI"), Ambac
Assurance Corporation ("AMBAC"), Asset Guaranty Reinsurance Company ("Asset
Guaranty"), 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.
Standard & Poor's has assigned an A claims-paying ability to ACA and an AA
claims-paying ability to AGI. The ratings are subject to change at any time at
the discretion of the rating agencies.

  The cost of this insurance is borne either by the issuers or previous owners
of the bonds. The Sponsor does not insure the bonds in conjunction with their
deposit in a Trust and makes no representations with regard to the adequacy of
the insurance covering any of the Insured Bonds. The insurance policies are
non-cancellable and will continue in force so long as the bonds are outstanding
and the insurers remain in business. The insurance policies guarantee the
timely payment of principal and interest on the Insured Bonds. However, the
insurance policies do not guarantee the market value of the Insured Bonds or
the value of the Units. The above 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.

Tax Exemption

  From time to time Congress considers proposals to tax the interest on state
and local obligations, such as the Bonds. The Supreme Court has concluded 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

                                      B-8
<PAGE>

adversely affect an investment in Units. See "Taxes" herein for a more detailed
discussion concerning the tax consequences of an investment in Units. Unit
holders are urged to consult their own tax advisers.

TAXES

  This is a general discussion of some of the income tax consequences of the
ownership of the Units. It applies only to investors who hold the Units as
capital assets. It does not discuss rules that apply to investors subject to
special tax treatment, such as securities dealers, financial institutions and
insurance companies.

The Bonds

  In the opinions of bond counsel delivered on the dates the Bonds were issued
(or in opinions to be delivered, in the case of when issued Bonds), the
interest on the Bonds is excludable from gross income for regular Federal
income tax purposes under the law in effect at that time (except in certain
circumstances because of the identity of the holder).
However, interest on the Bonds may be subject to other state and local taxes.
The Sponsor and Battle Fowler LLP have not made and will not make any review of
the procedures for the issuance of the Bonds or the basis for these opinions.

  In the opinions of bond counsel referred to above, none of the interest
received on the Bonds is subject to the alternative minimum tax for
individuals. However, the interest is includible in the calculation of a
corporation's alternative minimum tax.

  In the case of certain of the Bonds, the opinions of bond counsel indicate
that interest received by a substantial user of the facilities financed with
proceeds of the Bonds, or persons related thereto, will not be exempt from
regular Federal income taxes, although interest on those Bonds received by
others would be exempt. The term substantial user includes only a person whose
gross revenue derived with respect to the facilities financed by the issuance
of the Bonds is more than 5% of the total revenue derived by all users of those
facilities, or who occupies more than 5% of the usable areas of those
facilities or for whom those 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.

  The opinions of bond counsel may be limited to law existing at the time the
Bonds were issued, and may not apply to the extent that future changes in law,
regulations or interpretations affect such Bonds. Interest on some or all of
the Bonds may become subject to regular Federal income tax, perhaps
retroactively to their dates 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. Failure to meet these
requirements could cause the interest on the Bonds to become taxable, thereby
reducing the value of the Bonds, subjecting holders of the Bonds to
unanticipated tax liabilities and possibly requiring the Trustee to sell the
Bonds at reduced values.

  The Sponsor and Battle Fowler LLP have not made any investigation as to the
current or future owners or users of the facilities financed by the Bonds, the
amount of such persons' outstanding tax-exempt private activity bonds, or the
facilities themselves, and no one can give any assurance that future events
will not affect the tax-exempt status of the Bonds.

  From time to time Congress considers proposals to tax the interest on state
and local obligations, such as the Bonds and it can be expected that similar
proposals, including proposals
for a flat tax or consumption tax, may be introduced in the future. The Sponsor
cannot predict whether

                                      B-9
<PAGE>

additional legislation in respect of the Federal income tax status of interest
on state and local obligations may be enacted and what the effect of such
legislation would be on Bonds in the Trust. The Supreme Court has concluded
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, could adversely affect an investment in Units. The
decision does not, however, affect the current exemption from taxation of the
interest earned on the Bonds in the Trust.

  The Internal Revenue Service has expanded, and is continuing to expand its
examination program with respect to tax-exempt bonds. The expanded examination
program consists of, among other measures, increased enforcement against
abusive transactions, broader audit coverage and more comprehensive information
reporting on the tax-exempt bond information returns. These developments could
affect the Bonds.

  Investors should consult their tax advisors for advice with respect to the
effect of these provisions on their particular tax situation.

The Trust

  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 interest on the Bonds that is excludible from
  Federal gross income when received by the Trusts will be excludible from
  the Federal gross income of the Unit holders. Any proceeds paid under the
  insurance policies described above issued to the Trusts with respect to the
  Bonds and any proceeds paid under individual policies obtained by issuers
  of Bonds or other parties that represent maturing interest on defaulted
  obligations held by the Trusts will be excludible from Federal gross income
  to the same extent as such interest would have been excludable if paid in
  the normal course by the issuer of the defaulted obligations.

    Each Unit holder will be considered the owner of a pro rata portion of
  the Bonds and any other assets held in the Trust under the grantor trust
  rules of the Code. Each Unit holder will be considered to have received its
  pro rata share of income from Bonds held by the Trust on receipt by the
  Trust (or earlier accrual, depending on the Unit holder's method of
  accounting and depending on the existence of any original issue discount),
  and each Unit holder will have a taxable event when an underlying Bond is
  disposed of (whether by sale, redemption, or payment at maturity) or when
  the Unit holder redeems or sells its Units.

  The opinion of Battle Fowler LLP as to the tax status of the Trusts is not
affected by the provision of the Trust Agreement that authorizes the
acquisition of Replacement Bonds or by the implementation of the option
automatically to reinvest principal and interest distributions from the Trusts
pursuant to the Automatic Accumulation Plan, described under "Automatic
Accumulation Account" in this Part B.

Other Tax Issues

  The Trust may contain Bonds issued with original issue discount. The Code
requires Unit holders to accrue tax-exempt original issue discount by using the
constant interest method provided for the holders of taxable obligations and to
increase the basis of a tax-exempt obligation by the amount of accrued tax-
exempt original issue discount. These provisions are applicable to obligations
issued after September 3, 1982 and acquired after March 1, 1984. The Trust's
tax basis (and the Unit holder's tax basis) in a Bond is increased by any
accrued original issue discount. For Bonds issued after June 9, 1980 that are
redeemed prior to maturity, the difference between the Trust's basis, as
adjusted, and the amount received will be taxable gain or loss to the Unit
holders.


                                      B-10
<PAGE>

  Unit holders should consult their own tax advisors with respect to the state
and local tax consequences of owning original issue discount bonds. It is
possible that in determining state and local taxes, interest on tax-exempt
bonds issued with original issue discount may be deemed to be received in the
year of accrual even though there is no corresponding cash payment.

  The total cost of a Unit to a Unit holder, including sales charge, is
allocated among the Bonds held in the Trust (in proportion to the values of
each Bond) in order to determine the Unit holder's per Unit tax basis for each
Bond. The tax basis reduction requirements of the Code relating to amortization
of bond premium discussed below will apply separately to the per Unit cost of
each such Bond.

  A Unit holder will be considered to have purchased its pro rata interest in a
Bond at a premium when it acquires a Unit if its tax cost for its pro rata
interest in the Bond exceeds its pro rata interest in the Bond's face amount
(or the issue price plus accrued original issue discount of an original issue
discount bond). The Unit holder will be required to amortize any premium over
the period remaining before the maturity or call date of the Bond. Amortization
of premium on a Bond will
reduce a Unit holder's tax basis for its pro rata interest in the Bond, but
will not result in any deduction from the Unit holder's income. Thus, for
example, a Unit holder who purchases a Unit at a price that results in a Bond
premium and resells it at the same price will recognize taxable gain equal to
the portion of the premium that was amortized during the period the Unit holder
is considered to have held such interest.

  Bond premium must be amortized under the method the Unit holder regularly
employs for amortizing bond premium (assuming such method is reasonable). With
respect to a callable bond, the premium must be computed with respect to the
call price and be amortized to the first call date (and successively to later
call dates based on the call prices for those dates).

  Gain (or loss) realized on a sale, maturity or redemption of the Bonds or on
a sale or redemption of a Unit is includible in gross income for Federal, state
and local income tax purposes. That gain will be capital gain (or loss),
assuming that the Unit is held as a capital asset, except for any accrued
interest, accrued original issue discount or accrued market discount. When a
Bond is sold by the Trust, taxable gain or loss will be realized by the Unit
holder equal the difference between (i) the amount received (excluding the
portion representing accrued interest) and (ii) the adjusted basis (including
any accrued original issue discount). Taxable gain (or loss) will also result
if a Unit is sold or redeemed for an amount different from its adjusted basis
to the Unit holder. The amount received when a Unit is sold or redeemed is
allocated among all the Bonds in the Trust in the same manner if the Trust had
disposed of the Bonds, and the Unit holder may exclude accrued interest,
including any accrued original issue discount, but not amounts attributable to
market discount. The return of a Unit holder's tax basis is otherwise a tax-
free return of capital.

  A Unit holder may acquire its Units, or the Trust may acquire Bonds at a
price that represents a market discount for the Bonds. Bonds purchased at a
market discount tend to increase in market value as they approach maturity,
when the principal amount is payable, thus increasing the potential for taxable
gain (or reducing the potential for loss) on their redemption, maturity or
sale. Gain on the disposition of a Bond purchased at a market discount
generally will be treated as taxable ordinary income, rather than capital gain,
to the extent of accrued market discount. The administration's fiscal year 2000
budget proposal would require accrual basis taxpayers to accrue market discount
income with respect to obligations acquired after the date that the proposal is
enacted.

  Long-term capital gains realized by non-corporate Unit holders (with respect
to Units and

                                      B-11
<PAGE>

Bonds held for more than one year) will be taxed at a maximum federal income
tax rate of 20%, while ordinary income received by non-corporate Unit holders
will be taxed at a maximum federal income tax rate of 39.6%. The deductibility
of capital losses is limited to the amount of capital gain; in addition, up to
$3,000 of capital losses of noncorporate Unit holders ($1,500 in the case of
married individuals filing separate returns) may be deducted against ordinary
income. Since the proceeds from sales of Bonds, under certain circumstances,
may not be distributed pro-rata, a Unit holder's taxable income or gain for any
year may exceed its actual cash distributions in that year.

  If the Trust purchases any units of a previously issued series, based on the
opinion of counsel with respect to such series the Trust's pro rata ownership
interest in the bonds of such series (or any previously issued series) will be
treated as though it were owned directly by the Trust.

  Among other things, the Code provides for the following: (1) interest on
certain private activity bonds is an item of tax preference included in the
calculation of alternative minimum tax, however none of the Bonds in the Trust
is covered by this provision; (2) 75% of the amount by which adjusted current
earnings (including interest on all tax-exempt bonds) exceed alternative
minimum taxable income, as modified for this calculation, will be included in
corporate alternative minimum taxable income; (3) subject to certain
exceptions, no financial institution is allowed a deduction for interest
expense allocable to tax-exempt interest on bonds acquired after August 7,
1986; (4) the amount of the deduction
allowed to property and casualty insurance companies for underwriting loss is
decreased by an amount determined with regard to tax-exempt interest income and
the deductible portion of dividends received by such companies; (5) an issuer
must meet certain requirements on a continuing basis in order for interest on a
bond to be tax-exempt, with failure to meet such requirements resulting in the
loss of tax exemption; and (6) the branch profits tax on U.S. branches of
foreign corporations may have the effect of taxing a U.S. branch of a foreign
corporation on the interest on bonds otherwise exempt from tax.

  The Code provides that a portion of social security benefits is includible in
taxable income for taxpayers whose "modified adjusted gross income" combined
with a portion of their social security benefits exceeds a base amount. The
base amount is $25,000 for an individual, $32,000 for a married couple filing a
joint return and zero for married persons filing separate returns. Interest on
tax-exempt bonds is added to adjusted gross income for purposes of determining
whether an individual's income exceeds this base amount.

  Certain S corporations, with accumulated earnings and profits from years in
which they were subject to regular corporate tax, may be subject to minimum tax
on excess passive income, including tax-exempt interest.

  If borrowed funds are used by a Unit holder to purchase or carry Units of the
Trust, interest on such indebtedness will not be deductible for Federal income
tax purposes. Fees and expenses of the Trust will also not be deductible. 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 are
applicable for purposes of state and local taxation.

  After the end of each calendar year, the Trustee will furnish to each Unit
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 Unit holder and to the Internal Revenue Service. Unit holders
are required

                                      B-12
<PAGE>

to report to the Internal Revenue Service the amount of tax-exempt interest
received during the year.

EXPENSES AND CHARGES

Initial Expenses

  Investors will reimburse the Sponsor on a per Unit basis, all or a portion of
the estimated costs incurred in organizing 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. The estimated organization costs will be
paid to the Sponsor from the assets of a Trust as of the close of the initial
public offering period. To the extent that actual organization costs are less
than the estimated amount, only the actual organization costs will be deducted
from the assets of a Trust. To the extent that actual organization costs are
greater than the estimated amount, only the estimated organization costs added
to the Public Offering Price will be reimbursed to the Sponsor. Any balance of
the costs 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.

Fees

  The Trustee's, Evaluator's and Sponsor's fees are set forth under the Summary
of Essential Information. The Trustee receives for its services as Trustee
payable in monthly installments, the amount set forth under Summary of
Essential Information. The Trustee's fee is based on the principal amount of
Bonds contained in the Trust during the preceding month. The Trustee also
receives benefits to the extent that it holds funds on deposit in the various
non-interest bearing accounts created under the Indenture.

  The Evaluator's fee, which is earned for Bond evaluations, is received for
each evaluation of the Bonds in a Trust as set forth under Summary of Essential
Information.

  The Sponsor's fee, which is earned for trust supervisory services, is based
on the largest number of Units outstanding during the year. The Sponsor's fee,
which is not to exceed the maximum amount set forth under Summary of Essential
Information, may exceed the actual costs of providing supervisory services for
the Trust. However, at no time will the total amount the Sponsor receives for
trust supervisory services rendered to all series of Tax Exempt Securities
Trusts in any calendar year exceed the aggregate cost to it of supplying these
services in that year. In addition, the Sponsor may also be reimbursed for
bookkeeping or other administrative services provided to the Trust in amounts
not exceeding its cost of providing those services.

  The fees of the Trustee, Evaluator and Sponsor may be increased without
approval of Holders in proportion to increases under the classification "All
Services Less Rent" in the Consumer Price Index published by the United States
Department of Labor.

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, the Trust will also pay expenses associated with
updating the Trusts' registration statements and maintaining registration or
qualification of the Units and/or a Trust under Federal or state securities
laws subsequent to initial

                                      B-13
<PAGE>

registration. Such expenses shall include legal fees, accounting fees,
typesetting fees, electronic filing expenses and regulatory filing fees. The
expenses associated with updating registration statements have been
historically paid by a unit investment trust's sponsor. Any payments received
by the Sponsor reimbursing it for payments made to update Trusts' registration
statements will not exceed the costs incurred by the Sponsors.

  The Trusts shall further incur expenses associated with 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. All direct distribution expenses of the Trusts (including the costs
of maintaining the secondary market for the Trusts), such as printing and
distributing prospectuses, and preparing, printing and distributing any
advertisements or sales literature, will be paid at no cost to the Trusts.

PUBLIC OFFERING

Offering Price

  During the initial public offering period, the Public Offering Price of the
Units 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, as set forth in the table below. In
addition, during the initial public offering period a portion of the Public
Offering Price per Unit also consists of cash in an amount sufficient to pay
the per Unit portion of all or a part of the cost incurred in organizing and
offering a Trust. 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 to the
purchaser is also added to the Public Offering Price.

  During the initial public offering period, the sales charge and dealer
concession for the Trusts will be reduced as follows:

+ The reduced sales charge is also applied on a dollar basis utilizing a
  breakpoint equivalent in the above table of $1,000 for one Unit, etc. Units
  held in the name of the spouse or child under the age of 21 of the purchaser
  are deemed to be registered in the name of the purchaser for purposes of
  calculating the applicable sales charge.

  The holders of units of any unit investment trust sponsored by the Sponsor
(the "Exchangeable Series") may exchange units of the Exchangeable Series for
Units of a Trust of this Series at their relative net asset values, subject to
a fixed sales charge of $25 per Unit. See "Exchange Option" herein.

  The Sponsor may at any time change the amount by which the sales charge is
reduced, or discontinue the discount completely.

  Employees of the Sponsor and its subsidiaries, affiliates and employee-
related accounts may purchase Units at a Public Offering Price equal to the
Evaluator's determination of the aggregate offering price of the Bonds per Unit
plus a sales charge of .50%. In addition, during the initial public offering
period a portion of the Public Offering

                                      B-14
<PAGE>

Price per Unit also consists of cash in an amount sufficient to pay the per
Unit portion of all or a part of the cost incurred in organizing and offering a
Trust. After the initial public offering period such purchases may be made at a
Public Offering Price equal to the Evaluator's determination of the aggregate
bid price of the Bonds per Unit plus a sales charge of .50%. 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 OneSM Program and in the Reinvestment Program of any series of the Trust
may purchase Units at a Public Offering Price equal to the Evaluator's
determination of the aggregate offering price of the Bonds (plus cash held by
the Trust for organization and offering costs) 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 per Unit. Participants in the Smith Barney Asset OneSM 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 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. Following the initial public offering period, the
aggregate bid price of the Bonds 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. 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 of
the Bonds. 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%. 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.

Distribution of Units

  During the initial public offering period Units of a Trust will be
distributed to the public at the Public 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 may be offered by this Prospectus at the Public
Offering Price determined in the manner provided for secondary market sales.

  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." The Sponsor
reserves the right to change the amount

                                      B-15
<PAGE>

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 Holder or become entitled to exercise the rights
of a 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 Holder is
the Public Offering Price in effect at the time his order is received, plus
accrued interest. 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

  While the Sponsor is not obligated to do so, its intention is 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. 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 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 Holder
desiring to dispose of its Units may be able to do so by tendering such Units
to the Trustee for redemption at the Redemption Price.

Exchange Option

  Holders may exchange their Units of this series for units of any series of
Tax Exempt Securities Trust (the "Exchange Trust") available for sale in the
state in which the Holder resides. Such exchange will be 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 terms of the Exchange Option will also apply to
holders who wish to exchange units of an Exchangeable Series for Units of a
Trust of this Series. The Sponsor reserves the right to modify, suspend or
terminate this plan at any time without further notice to Holders. Therefore,
there is no assurance that the Exchange Option will be available to a 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, or units of an Exchangeable Series for Units of a 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, or units of
an Exchangeable Series for Units of a Trust of this Series, 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. 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 or a Trust of this Series will be sold under the
Exchange Option at the bid prices (for trusts being offered in the secondary
market) and offer prices (for trusts being offered in the primary market) of
the underlying securities in the particular portfolio involved per unit plus a
fixed charge of $25 per unit. Sales to dealers will be made at prices which
represent a concession. The amount of the concession will be established at the
time of sale by the Sponsor. As an example, assume that a 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,

                                      B-16
<PAGE>


the proceeds from the Unit holder's units will aggregate $3,060. Since only
whole units of an Exchange Trust or a Trust may be purchased under the Exchange
Option, the Holder would be able to acquire three units in the Exchange Trust
for a total cost of $2,715 ($2,640 for the units and $75 for the sales charge)
and would also receive $345 for the fractional Unit.

Reinvestment Programs

  Distributions of interest and/or principal are made to Holders monthly. The
Holder has the option of either receiving a monthly income check from the
Trustee or participating in one of the reinvestment programs offered by the
Sponsor provided such Holder meets the minimum qualifications of the
reinvestment program and such program lawfully qualifies for sale in the
jurisdiction in which the Holder resides. Upon enrollment in a reinvestment
program, the Trustee will direct monthly interest distributions and principal
distributions to the reinvestment program selected by the Holder. Since the
Sponsor has arranged for different reinvestment alternatives Holders should
contact the Sponsor for more complete information, including charges and
expenses. The appropriate prospectus will be sent to the Holder. The 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 Holder and may be terminated at any time by the
Holder. The program may also be modified or terminated by the Trustee or the
program's Sponsor.

Sponsor's and Underwriters' Profits

  The Underwriters receive a commission based on the sales charge of a
particular Trust 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 in
the amount of any difference between the cost of the Bonds to a Trust and the
purchase price of such Bonds to the Sponsor. 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 Deposit in the offering
prices of the Bonds and hence in the Public Offering Price received by the
Underwriters for Units. Cash 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.

  In maintaining a market for the 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.

RIGHTS OF HOLDERS

Certificates

  Ownership of Units may be 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 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 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.

                                      B-17
<PAGE>

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 Holders of record in such
Trust 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
Holders on previous Distribution Dates.

  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. 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 Holders as of each
Record Date will be made on the following Distribution Date or shortly
thereafter. Such distributions 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 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 Summary of Essential Information for a Trust. The
Monthly Income Distribution 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 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 then be reimbursed, without interest, for any such advances from
funds available from the Interest Account on the next ensuing Record Date. 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 such advances 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, each
remaining Holder will be subject to a greater pro rata reduction in his Monthly
Interest Distribution. To the extent it is unable to recoup advances from the
Interest Account, the Trustee is also entitled to withdraw from the Principal
Account. Funds which are available for future distributions, payments of
expenses and redemptions are in accounts which are non-interest bearing to
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, accrued interest may at any point
in time be greater than the amount of interest distributed to Holders. This
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 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 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.

                                      B-18
<PAGE>

  As of the first day of each month the Trustee will deduct from the Interest
Account of a Trust amounts necessary to pay the expenses of such Trust. To the
extent there are not sufficient funds in the Interest Account to pay Trust
expenses, the Trustee is also entitled to withdraw from the Principal Account.
The Trustee also may withdraw from the accounts such amounts 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 returns 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.

  The Trustee has agreed to advance to a Trust the amount of accrued interest
due on the Bonds 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 advances 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 Holders in connection with each distribution a
statement of the amount of interest and the amount of other receipts 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 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 Holder of record,
a statement (1) as to the Interest Account: interest received, 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. 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 Holders upon request.

  The Trustee shall keep available for inspection by Holders at all reasonable
times during usual
                                      B-19
<PAGE>

business hours, books of record and account of its transactions as Trustee
including records of the names and addresses of 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 canceled.

  Certificates for Units to be redeemed must be properly endorsed or
accompanied by a written instrument of transfer. 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 Holder will be entitled
to receive in cash an amount for each Unit tendered equal to the 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.

  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 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 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 Holders
of such Trust of record as of a date prior to the evaluation. As of the close
of the initial public offering period the Redemption Price per Unit will be
reduced to reflect the organization costs per Unit of a Trust. To the extent
that actual organization costs are less than the estimated amount, only the
actual organization costs will be deducted from the assets of a Trust.

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

                                      B-20
<PAGE>

close of business on the second succeeding business day, will purchase any
Units tendered to the Trustee. Such a purchase by the Sponsor will be at the
price so bid by making payment to the Holder in an amount not less than the
Redemption Price and not later than the day on which the Units would otherwise
have been redeemed by the Trustee.

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

SPONSOR

  Salomon Smith Barney Inc. ("Salomon Smith Barney"), was incorporated in
Delaware in 1960 and traces its history through predecessor partnerships to
1873. On September 1, 1998, Salomon Brothers Inc. merged with and into Smith
Barney Inc. ("Smith Barney") with Smith Barney surviving the merger and
changing its name to Salomon Smith Barney Inc. The merger of Salomon Brothers
Inc. and Smith Barney followed the merger of their parent companies in November
1997. Salomon Smith Barney, an investment banking and securities broker-dealer
firm, is a member of the New York Stock Exchange, Inc. and other major
securities and commodities exchanges, the National Association of Securities
Dealers, Inc. and the Securities Industry Association. Salomon Smith Barney is
an indirect wholly-owned subsidiary of Citigroup Inc. Salomon 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. Salomon Smith Barney also sponsors all Series of
Corporate Securities Trust, Government Securities Trust, Harris, Upham Tax-
Exempt Fund and Tax Exempt Securities Trust, and acts as sponsor of most Series
of Defined Assets Funds.

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
Holders for taking any action or refraining from any action in good faith or
for errors in judgment. The Sponsor shall also not be 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.

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. Such events include: 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 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. However, 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.

                                      B-21
<PAGE>

  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 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 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 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.

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 Holders may rely on any evaluation furnished by the
Evaluator and shall

                                      B-22
<PAGE>

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 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.

Resignation

  The Evaluator may resign or may be removed by the joint action of the Sponsor
and the Trustee. Should such removal occur, 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 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 Holders. However, the Trust Agreement may not be amended to
increase the number of Units issuable 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. In the event of any amendment, the Trustee is
obligated to notify promptly all Holders of the substance of such amendment.

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 Holders. However, in no event may a Trust continue beyond
the Mandatory Termination Date set forth under "Summary of Essential
Information." In the event of termination, written notice thereof will be sent
by the Trustee to all Holders. Within a reasonable period after termination,
the Trustee will sell any Bonds remaining in the affected Trust. Then after
paying all expenses and charges incurred by such Trust, the Trustee will
distribute to each 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.

MISCELLANEOUS

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 LLP, independent

                                      B-23
<PAGE>

auditors, as indicated in their report with respect thereto, and are included
herein in reliance upon the authority of said firm as experts in accounting and
auditing.

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.

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.


- ------------
+ As described by the rating agencies.

                                      B-24
<PAGE>

  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 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

                                      B-25
<PAGE>

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-26

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 effective Federal income tax rates and tax brackets for the
1999 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.

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 $126,600, 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 Federal 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 $189,950 for
    married taxpayers filing a joint tax return and $126,600 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
    indicated within each bracket.
  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.

- --------------------------------------------------------------------------------
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.

California Trust

  Risk Factors--The following information is a brief summary of factors
affecting the economy of the State of California and does not purport to be a
complete description of such factors. Other factors will affect issuers. The
summary is based primarily upon one or more publicly available offering

  General Economic Conditions. The economy of the State of California
(sometimes referred to herein as the "State") is the largest among the 50
states and one of the largest in the world. This diversified economy has major
components in agriculture, manufacturing, high technology, trade,
entertainment, tourism, construction and services.

  California's January 1, 1999 population is estimated to be over 33.7 million
people.

  California's population is concentrated in metropolitan areas. As of the
April 1, 1990 census, 96% resided in the 23 Metropolitan Statistical Areas in
the State. As of July 1, 1998, the five-county Los Angeles area accounted for
49%, with 16.0 million residents. The 10-county San Francisco Bay Area
represented 21%, with a population of 7.0 million.

  California: 1995-96 through 1998-99 Fiscal Years. From 1990-1993, the State
suffered through a severe recession. The State's financial condition improved
markedly during the 1995-96 through 1998-99 fiscal years, with a combination of
better than expected revenues, slowdown in growth of social welfare programs,
and continued spending restraint based on the actions taken in earlier years.
The State's cash position also improved, and no external deficit borrowing has
occurred over the end of these four fiscal years. The last borrowing to spread
out the repayment of a budget deficit over the end of a fiscal year was $4.0
billion of revenue anticipation warrants issued in July, 1994 which matured in
April, 1996.

  The economy grew strongly during these fiscal years, and as a result, the
General Fund took in substantially greater tax revenues (around $2.2 billion in
1995-96, $1.6 billion in 1996-97, $2.4 billion in 1997-98 and $1.0 billion in
1998-99) than were initially planned when the budgets were enacted. These
additional funds were largely directed to school spending as mandated by
Proposition 98, and to make up shortfalls from reduced federal health and
welfare aid in 1995-96 and 1996-97 and particularly in 1998-99 to fund program
incentives. The accumulated budget deficit from the recession years was finally
eliminated. The Department of Finance estimated that the State's budget reserve
(SFEU) totaled $639.8 million as of June 30, 1997 and $1.782 billion at June
30, 1998. As of May 14, 1999, the Department of Finance projected that the SFEU
would have a balance of about $1.881 billion as of June 30, 1999 and $985
million as of June 30, 2000.

  The 1998-99 Fiscal Year Budget. The following were major features of the 1998
Budget Act and certain additional fiscal bills enacted before the end of the
legislative session:

  1. The most significant feature of the 1998-99 budget was agreement on a
total of $1.4 billion of tax cuts. The central element was a bill which
provided for a phased-in reduction of the Vehicle License Fee ("VLF"). Since
the VLF is transferred to cities and counties under existing law, the bill
provided for the general fund to replace the lost revenues. Starting on January
1, 1999, the VLF has been reduced by 25 percent, at a cost to the general fund
of approximately $500 million in the 1998-99 fiscal year and about $1 billion
annually thereafter.

  In addition to the cut in VLF, the 1998-99 budget included both temporary and
permanent increases in the personal income tax dependent credit ($612 million
general fund cost in 1998-99, but less in future years), a nonrefundable
renters tax credit ($133 million), and various targeted business tax credits
($106 million).

  2. Proposition 98 funding for K-14 schools was increased by $1.7 billion in
general fund moneys over revised 1997-98 levels, over $300 million higher than
the minimum Proposition 98 guarantee. Of the 1998-99 funds, major new programs
included money for instructional and library materials, deferred maintenance,
support for increasing the school year to 180 days and reduction of class sizes
in Grade 9. The Budget also included $250 million as repayment of prior years'
loans to schools, as part of the settlement of the California Teachers'
Association v. Gould lawsuit.

  3. Funding for higher education increased substantially above the actual
1997-98 level. General fund support was increased by $340 million (15.6
percent) for the University of California and $267 million (14.1 percent) for
the California State University system. In addition, Community Colleges funding
increased by $300 million (6.6 percent).

  4. The Budget included increased funding for health, welfare and social
services programs. A 4.9 percent grant increase was included in the basic
welfare grants, the first increase in those grants in 9 years.

  5. Funding for the judiciary and criminal justice programs increased by about
11 percent over 1997-98, primarily to reflect increased State support for local
trial courts and rising prison population.

  6. Major legislation enacted after the 1998 Budget Act included new funding
for resources projects, a share of the purchase of the Headwaters Forest,
funding for the Infrastructure and Economic Development Bank ($50 million) and
funding for the construction of local jails. The State realized savings of $433
million from a reduction in the State's contribution to the State Teachers'
Retirement System in 1998-99.

  The May Revision to the 1999-2000 Governor's Budget (hereafter shortened to
"1999-00"), released on May 14, 1999 (the "1999 May Revision"), reported that
stronger than expected economic conditions in the State for the latter part of
1998 and into 1999 would produce total 1998-99 general fund revenues of about
$57.9 billion, almost $1.0 billion above the 1998 Budget Act estimates and $1.6
billion above the initial estimates in the January 1999-2000 Governor's Budget.
The 1999 May Revision projects 1998-99 general fund expenditures of $58.6
billion, about $400 million higher than the January 1999-2000 Governor's Budget
estimate. Some of this additional revenue will be directed to K-14 schools
pursuant to Proposition 98. The 1999 May Revision projected a balance in the
Special Fund for Economic Uncertainties (the "SFEU") at June 30, 1999, of
approximately $1.9 billion, $1.3 billion higher than estimated in January.

  1999-2000 Fiscal Year. On January 8, 1999, Governor Davis released his
proposed budget for fiscal year 1999-00 (the "January Governor's Budget"). The
January Governor's Budget generally reported that general fund revenues for
fiscal year 1998-99 and fiscal year 1999-00 would be lower than earlier
projections (primarily due to weaker overseas economic conditions perceived in
late
                                      C-2
<PAGE>

1998), while some welfare caseloads would be higher than earlier projections.
The January Governor's Budget proposed $60.5 billion of general fund
expenditures in fiscal year 1999-00, with a $415 million SFEU reserve at June
30, 2000.

  The 1999 May Revision showed an additional $4.3 billion of revenues for
combined fiscal years 1998-99 and 1999-00. The completion of the 1999 Budget
Act occurred in a timely fashion. The final Budget Bill was adopted by the
Legislature on June 16, 1999, and was signed by the Governor on June 29, 1999
(the "1999 Budget Act"), meeting the Constitutional deadline for budget
enactment for only the second time in the 1990's.

  The final 1999 Budget Act estimated general fund revenues and transfers of
$63.0 billion, and contained expenditures totaling $63.7 billion after the
Governor used his line-item veto to reduce the legislative Budget Bill
expenditures by $581 million (both general fund and special fund). The 1999
Budget Act also contained expenditures of $16.1 billion from special funds and
$1.5 billion from bond funds. The Administration estimated that the SFEU would
have a balance at June 30, 2000, of about $881 million. Not included in this
amount was an additional $300 million which (after the Governor's vetoes) was
"set aside" to provide funds for employee salary increases (to be negotiated in
bargaining with employee unions), and for litigation reserves. The 1999 Budget
Act anticipates normal cash flow borrowing during the fiscal year.

  The principal features of the 1999 Budget Act include the following:

  1. Proposition 98 funding for K-12 schools was increased by $1.6 billion in
general fund moneys over revised 1998-99 levels, $108.6 million higher than the
minimum Proposition 98 guarantee. Of the 1999-00 funds, major new programs
included money for reading improvement, new textbooks, school safety, improving
teacher quality, funding teacher bonuses, providing greater accountability for
school performance, increasing preschool and after school care programs and
funding deferred maintenance of school facilities. The Budget also includes
$310 million as repayment of prior years' loans to schools, as part of the
settlement of the California Teachers' Association v. Gould lawsuit.

  2. Funding for higher education increased substantially above the actual
1998-99 level. General fund support was increased by $184 million (7.3 percent)
for the University of California ("UC") and $126 million (5.9 percent) for the
California State University ("CSU") system. In addition, community colleges
funding increased by $324.3 million (6.6 percent). As a result, undergraduate
fees at UC and CSU will be reduced for the second consecutive year, and the
per-unit charge at community colleges will be reduced by $1.

  3. The Budget included increased funding of nearly $600 million for health
and human services.

  4. About $800 million from the general fund will be directed toward
infrastructure costs, including $425 million in additional funding for the
Infrastructure Bank, initial planning costs for a new prison in the Central
Valley, additional equipment for train and ferry service, and payment of
deferred maintenance for state parks.

  5. The Legislature enacted a one-year additional reduction of 10 percent of
the VLF for calendar year 2000, at a general fund cost of about $250 million in
each of fiscal year 1999-00 and 2000-01 to make up lost funding to local
governments. Conversion of this one-time reduction to a permanent cut will
remain subject to the revenue tests in the legislation adopted last year.
Several other targeted tax cuts, primarily for businesses, were also approved,
at a cost of $54 million in 1990-00

  6. A one-time appropriation of $150 million, to be split between cities and
counties, was made to offset property tax shifts during the early 1990's.
Additionally, an ongoing $50 million was appropriated as a subvention to cities
for jail booking or processing fees charged by counties when an individual
arrested by city personnel is taken to a county detention facility.

  Local Government. The primary units of local government in California are the
counties, ranging in population from 1,200 (Alpine) to over 9,600,000 (Los
Angeles). Counties are responsible for the provision of many basic services,
including indigent healthcare, welfare, courts, jails and public safety in
unincorporated areas. There are also about 470 incorporated cities and
thousands of other special districts formed for education, utility and other
services. The fiscal condition of local governments has been constrained since
the enactment of "Proposition 13" in 1978, which reduced and limited the future
growth of property taxes and limited the ability of local governments to impose
"special taxes" (those devoted to a specific purpose) without two-thirds voter
approval. Counties, in particular, have had fewer options to raise revenues
than many other local government entities, and have been required to maintain
many services.

  The entire statewide welfare system has been changed in response to the
change in federal welfare law enacted in 1996. Under the new basic state
welfare system, California Work Opportunity and Responsibility to Kids
("CalWORKs"), counties are given flexibility to develop their own plans,
consistent with State law, to implement Welfare-to-Work and to administer many
of its elements and their costs for administrative and support services are
capped at 1996-97 levels. Counties are also given financial incentives if, at
the individual county level or statewide, the CalWORKs program produces savings
associated with specified Welfare-to-Work outcomes; counties may also suffer
penalties for failing to meet federal standards. Under CalWORKs, counties will
still be required to provide "general assistance" aid to certain persons who
cannot obtain welfare from other programs.

  The long-term impact of the new federal Law and CalWORKS cannot be determined
until there has been more experience and until an independent evaluation of the
CalWORKS program is completed. In the short-term, the implementation of the
CalWORKS program has continued the trend of declining welfare caseloads. The
CalWORKS caseload trend is projected to be 646,000 in 1998-99 and 602,000 in
1999-00, down from a high of 921,000 cases in 1994-95.

  The 1999 Budget Act proposes expenditures that will continue to meet, but not
exceed, the federally-required $2.9 billion combined State and county
maintenance-of-effort requirement. Total CalWORKS-related expenditures are
estimated to be $7.3 billion for 1998-99 and $7.3 billion for 1999-00,
including child care transfer amounts for the Department of Education.

  Historically, funding for the State's trial court system was divided between
the State and the counties. However, Chapter 850, Statutes of 1997, implements
a restructuring of the State's trial court funding system. In 1997-98, funding
for the courts, with the exception of costs for facilities, local judicial
benefits, and revenue collection, was consolidated at the State level. The
county contribution for both their general fund and fine and penalty amounts is
capped at the 1994-95 level and becomes part of the Trial Court Trust Fund,
which supports all trial court operations. The State assumes responsibility for
future growth in trial court funding. This consolidation is intended to
streamline the operation of the courts, provide a dedicated revenue source, and
relieve fiscal pressure on the counties. Beginning in 1998-99, county general
fund contribution for court operations is reduced by $300 million, including
$10.7 million to buy out the contribution of the 20 smallest counties, and
cities will retain $62 million in fine and penalty revenue previously remitted
to the State; the State's general fund reimbursed the $362 million revenue loss
to the Trial Court Trust Fund. The 1999 Budget Act includes funds to further
reduce the county general fund contribution by an additional $96 million by
reducing by 100 percent the contributions of the next 18 smallest counties and
by 10 percent the general fund contribution of the remaining 21 counties.

  In the aftermath of Proposition 13, the State provided aid from the General
Fund to make up some of the loss of property tax moneys, including
                                      C-4

taking over the principal responsibility for funding local K-12 schools and
community colleges. During the recession in the early 1990's, the Legislature
has eliminated the remnants of post-Proposition 13 aid to entities other than
K-14 education districts, although it has also provided additional funding
sources (such as sales taxes) and reduced mandates for local services. Many
counties continue to be under severe fiscal stress. While such stress has in
recent years most often been experienced by smaller, rural counties, larger
urban counties, such as Los Angeles, have also been affected. Since then the
State has also provided additional funding to counties and cities through such
programs as health and welfare realignment, welfare reform, trial court
restructuring, an annual program supporting local public safety departments
called the Citizens' Option for Public Safety (COPS) Program, and various other
measures. In his 1999-00 Budget Proposal, the Governor has proposed a review
and "accounting" of state--local fiscal relationships, with the goal of
ultimately restoring local government finances to an equivalent fiscal
condition to the period prior to the 1991-93 recession--induced tax shifts.
Litigation has been brought challenging the legality of the property tax shifts
from counties to schools.

  On November 5, 1996, voters approved Proposition 218, entitled the "Right to
Vote on Taxes Act," which incorporates new Articles XIIIC and XIIID into the
California Constitution. These new provisions enact limitations on the ability
of local government agencies to impose or raise various taxes, fees, charges
and assessments without voter approval. Certain "general taxes" imposed after
January 1, 1995 must be approved by voters in order to remain in effect. In
addition, Article XIIIC clarifies the right of local voters to reduce taxes,
fees, assessments or charges through local initiatives. There are a number of
ambiguities concerning the Proposition and its impact on local governments and
their bonded debt which will require interpretation by the courts or the State
Legislature. The State Legislative Analyst estimated that enactment of
Proposition 218 would reduce local government revenues statewide by over $100
million a year, and that over time, annual revenue to local government would be
reduced by several hundred million dollars. Proposition 218 does not affect the
State or its ability to levy or collect taxes.

  On December 24, 1997, a consortium of California counties filed a test claim
with the Commission on State Mandates (the "Commission") asking the Commission
to determine whether the property tax shift from counties to the Educational
Revenue Augmentation Fund, which is a funding source for schools, is a
reimbursable state mandated cost. The test claim was heard on October 29, 1998,
and the Commission on State Mandates found in favor of the State. In March,
1999, Sonoma County filed suit in the Superior Court to overturn the
Commission's decision. The State is contesting this lawsuit. Should the courts
find in favor of the counties, the impact to the State general fund could be as
high as $10.0 billion with an annual Proposition 98 general fund cost of at
least $3.6 billion. This cost would grow in accordance with the annual assessed
value growth rate.

  Constitutional and Statutory Limitations; Recent Initiatives; Pending
Legislation. Article XIIIA of the California Constitution (which resulted from
the voter-approved Proposition 13 in 1978) limits the taxing powers of
California public agencies. Article XIIIA provides that the maximum ad valorem
tax on real property cannot exceed one percent of the "full cash value" of the
property and effectively prohibits the levying of any other ad valorem tax on
real property for general purposes. However, on May 3, 1986, Proposition 46, an
amendment to Article XIIIA, was approved by the voters of the State of
California, creating a new exemption under Article XIIIA permitting an increase
in ad valorem taxes on real property in excess of one percent for bonded
indebtedness approved by two-thirds of the voters voting on the proposed
indebtedness. "Full cash value" is defined as "the county assessor's valuation
of real property as shown on the 1975-76 tax bill under "full cash value' or,
thereafter, the appraised value of real
                                      C-5
<PAGE>

property when purchased, newly constructed, or a change in ownership has
occurred after the 1975 assessment." The "full cash value" is subject to annual
adjustment to reflect increases (not to exceed two percent) or decreases in the
consumer price index or comparable local data, or to reflect reductions in
property value caused by damage, destruction or other factors.

  Article XIIIB of the California Constitution limits the amount of
appropriations of the State and of the local governments to the amount of
appropriations of the entity for the prior year, adjusted for changes in the
cost of living, population and the services that local government has financial
responsibility for providing. To the extent that the revenues of the State
and/or local government exceed its appropriations, the excess revenues must be
rebated to the public either directly or through a tax decrease. Expenditures
for voter-approved debt services are not included in the appropriations limit.

  On November 8, 1988, voters of the State approved Proposition 98, a combined
initiative constitutional amendment and statute called the "Classroom
Instructional Improvement and Accountability Act." Proposition 98 changed State
funding of public education below the university level and the operation of the
State appropriations limit, primarily by guaranteeing K-14 schools a minimum
share of general fund revenues. Under Proposition 98 (as modified by
Proposition 111, which was enacted on June 5, 1990), K-14 schools are
guaranteed the greater of (a) in general, a fixed percent of general fund
revenues ("Test 1"), (b) the amount appropriated to K-14 schools in the prior
year, adjusted for changes in the cost of living (measured as in California
Constitution Article XIII B by reference to State per capita personal income)
and enrollment ("Test 2"), or (c) a third test, which would replace Test 2 in
any year when the percentage growth in per capita general fund revenues from
the prior year plus one half of one percent is less than the percentage growth
in State per capita personal income ("Test 3"). Under Test 3, schools would
receive the amount appropriated in the prior year adjusted for changes in
enrollment and per capita general fund revenues, plus an additional small
adjustment factor. If Test 3 is used in any year, the difference between Test 3
and Test 2 would become a "credit" to schools which would be the basis of
payments in future years when per capita general fund revenue growth exceeds
per capita personal income growth. Legislation adopted prior to the end of the
1988-89 fiscal year, implementing Proposition 98, determined the K-14 schools'
funding guarantee under Test 1 to be 40.3 percent of the general fund tax
revenues, based on 1986-87 appropriations. However, that percent has been
adjusted to approximately 35 percent to account for a subsequent redirection of
local property taxes, since such redirection directly affects the share of
general fund revenues to schools.

  During the recession in the early 1990's, general fund revenues for several
years were less than originally projected, so that the original Proposition 98
appropriations turned out to be higher than the minimum percentage provided in
the law. The Legislature responded to these developments by designating the
"extra" Proposition 98 payments in one year as a "loan" from future years'
Proposition 98 entitlements and also intended that the "extra" payments would
not be included in the Proposition 98 "base" for calculating future years'
entitlement. By implementing these actions, per-pupil funding from Proposition
98 sources stayed almost constant at approximately $4,220 from fiscal year
1991-92 to fiscal year 1993-94.

  In 1992, a lawsuit was filed, called California Teachers' Association v.
Gould, which challenged the validity of these off-budget loans. The settlement
of this case, finalized in July 1996, provides, among other things, that both
the State and K-14 schools share in the repayment of prior years' emergency
loans to schools. Of the total $1.76 billion in loans, the State will repay
$935 million by forgiveness of the amount owed, while schools will repay $825
million. The State's share of the repayment will be reflected as an
appropriation above the current Proposition 98 base calculation. The schools'
share
                                      C-6
<PAGE>

of the repayment will count as appropriations that count toward satisfying the
Proposition 98 guarantee, or from "below" the current base. Repayments are
spread over the eight-year period of 1994-95 through 2001-02 to mitigate any
adverse fiscal impact.

  Substantially increased general fund revenues, above initial budget
projections, in the 1994-95 through 1998-99 fiscal years have resulted or will
result in retroactive increases in Proposition 98 appropriations from
subsequent fiscal years' budgets. Furthermore, since General Fund revenue
growth is expected to continue in 1999-00, there are also new initiatives
proposed to increase school safety, provide additional textbooks to schools,
fund deferred maintenance projects, and expand after school programs and pre-
school.

  On November 8, 1994, the voters approved Proposition 187, an initiative
statute ("Proposition 187"). Proposition 187 specifically prohibits funding by
the State of social services, health care services and public school education
for the benefit of any person not verified as either a United States citizen or
a person legally admitted to the United States. Among the provisions in
Proposition 187 pertaining to public school education, the measure requires,
commencing January 1, 1995, that every school district in the State verify the
legal status of every child enrolling in the district for the first time. By
January 1, 1996, each school district was to have verified the legal status of
children already enrolled in the district and of all parents or guardians of
all students.

  Opponents of Proposition 187 filed at least eight lawsuits (which were
subsequently consolidated) challenging the constitutionality and validity of
the measure. On March 18, 1998, a United States District Court judge entered a
final judgment in the case, holding key portions of the measure
unconstitutional and permanently enjoining the State from implementing those
sections which would have required law enforcement, teachers and social
services and health care workers to verify a person's immigration status and
subsequently report illegal immigrants to authorities and deny them social
services, health care and education benefits. An appeal was filed by the former
California State Attorney General in the U.S. Court of Appeals in the 9th
Circuit. Governor Gray Davis subsequently asked the United States Ninth Circuit
Court of Appeal to serve as mediator on the issue. On April 26, 1999, the Ninth
Circuit Court of Appeal granted Governor Davis' request for mediation of the
controversy. In response, David E. Lombardi, Chief Mediator for Ninth Circuit
Mediation Office, ordered a stay until June 18, 1999 of all appellate
proceedings in connection with six cases before the Court of Appeal involving
Proposition 187 challenges. On June 1, 1999, the Howard Jarvis Taxpayers'
Association sued Governor Davis in the California Supreme Court challenging
Governor Davis' right to submit Proposition 187 to mediation, which the
plaintiff claims undermines the public's right of initiative. On June 30, 1999,
the California Supreme Court declined to hear the case. Since that time,
Governor Davis had the State's appeal withdrawn, letting stand the District
Court rulings.

  At the November 1998, elections voters approved Proposition 2. This
proposition required the general fund to repay loans made from certain
transportation special accounts (such as the State Highway Account) at least
once per fiscal year, or up to 30 days after adoption of the annual budget act.
Since the general fund may reborrow from the transportation accounts soon after
the annual repayment is made, the proposition is not expected to have any
adverse impact on the State's cash flow.

  Pending Litigation. The State is a party to numerous legal proceedings, many
of which normally occur in governmental operations. Some of the more
significant lawsuits pending against the State are described herein.

  The State is a defendant in Professional Engineers in California Government
v. Wilson, in which the petitioners have challenged several appropriations in
the 1993, 1994, and 1995 Budget
                                      C-7
<PAGE>

Acts. These appropriations mandate the transfer of $258.2 million from the
State Highway Account, within the special revenue funds, and $130.9 million
from the Motor Vehicle Account, within the special revenue funds, to the
general fund, and appropriate approximately $6 million from the State Highway
Account to fund a highway-grade crossing program administered by the Public
Utilities Commission. The petitioners have also challenged a $130 million
transfer from the State Highway Account to the Motor Vehicle Account. The
petitioners contend that these transfers violate several constitutional
provisions. In December 1998, the Superior Court ruled that $30.7 million of
the $258.2 million transferred from the State Highway Account to the general
fund violated the California Constitution. The court also invalidated $130.9
million transferred from the Motor Vehicle Account to the general fund. On
April 30, 1999, the court found that the $130 million transfer from the State
Highway Account to the Motor Vehicle Account also violated the California
Constitution. The State decided not to appeal this case and reversed the
challenged transfers pursuant to the court's decision.

  In Capitola Land v. Anderson and other related state and federal cases,
plaintiffs sought payments from the State under the AFDC-Foster Care program.
Judgment was rendered against the State in Capitola, which the State appealed
and lost. The State then filed a state plan amendment with the federal
Department of Health and Human Services to enable the State to comply with the
Capitola ruling and receive federal funding. The DHHS denied the state plan
amendment, and the State has filed suit against DHHS. The Legislature also
enacted a statute which required federal funding in order to comply with the
Capitola judgment. The State then refused to implement the Capitola judgment
based on the new statute. Certain plaintiffs moved for an order of contempt
against the State, which was granted by the trial court, but was stayed and
annulled by the Court of Appeal. The plaintiffs are petitioning the California
Supreme Court for review. If, as a result of this litigation, compliance with
the Capitola judgment is required and the judgment is applied retroactively,
liability to the State could exceed $200 million.

  In January of 1997, California experienced major flooding in six different
areas with preliminary estimates of property damage of approximately $1.6 to
$2.0 billion. A substantial number of plaintiffs have joined suit against the
State, local agencies, and private companies and contractors seeking
compensation for the damages they suffered as a result of the 1997 flooding.
The State is vigorously defending the action.

  In Just Say No to Tobacco Dough Campaign v. State of California, the
petitioners challenge the appropriation of approximately $166 million of
Proposition 99 funds in the Cigarette and Tobacco Products Surtax Fund for
years ended June 30, 1990, through June 30, 1995, for related disease research.
If the State loses, the general fund and funds from other sources would be used
to reimburse the Cigarette and Tobacco Products Surtax Fund, an agency fund,
for approximately $166 million. However, the superior court issued an order in
December 1998, granting the State's demurrer to the entire action and
dismissing the case. The superior court thereafter reconsidered its ruling and
allowed plaintiffs to amend their complaint. The State demurred to the amended
complaint. In July, 1999 the court again sustained the State's demurrer to the
amended complaint, and issued a judgment dismissing the case. Plaintiffs
appealed. The matter will be briefed and will be scheduled for oral argument
before the court.

  The State is a defendant in Ceridian Corporation v. Franchise Tax Board, a
suit which challenges the validity of two sections of the California Tax Laws.
The first relates to deduction from corporate taxes for dividends received from
insurance companies to the extent the insurance companies have California
activities. The second relates to corporate deduction of dividends to the
extent the earnings of the dividend paying corporation have already been
included in the measure of their California tax. On August 13, 1998,
                                      C-8
<PAGE>

the court issued a judgment against the Franchise Tax Board on both issues. The
Franchise Tax Board has appealed the judgment. If both sections of the
California tax law are invalidated, and all dividends become deductible, in the
future, general fund collections would be reduced annually in the $200-$250
million range for all taxpayers.

  The State is a defendant in an action, Emily Q., et al. v. Belshe, et al., to
compel a change in early screening procedures for children with mental health
needs. The lawsuit is limited to Los Angeles County. The State has filed an
answer in this case. An adverse outcome is possible with the protential
liability of $500 million per year.

  Plaintiffs in County of San Bernardino v. Barlow Respiratory Hospital and
related actions seek mandamus relief requiring the State to retroactively
increase out-patient Medi-Cal reimbursement rates. Plaintiffs have estimated
the damages to be several hundred million dollars. The State is vigorously
defending these cases, as well as related federal cases addressing the
calculation of Medi-Cal reimbursement rates in the future.

  The State is involved in a lawsuit, Thomas Hayes v. Commission on State
Mandates, related to state-mandated costs. The action involves an appeal by the
Director of Finance from a 1984 decision by the State Board of Control (now
succeeded by the Commission on State Mandates). The Board of Control decided in
favor of local school districts' claims for reimbursement for special education
programs for handicapped students. The case was then brought to the trial court
by the State and later remanded to the Commission for redetermination. The
Commission on State Mandates expanded the claim to include supplemental claims
filed by seven other educational institutions. To date, the Legislature has not
appropriated funds. The liability to the State, if all potentially eligible
school districts pursue timely claims, has been estimated by the Department of
Finance at more than $1 billion. In December 1998, the Commission issued a
decision determining that a portion, but not all, of the claims constituted
state mandated local costs. The Commission is now developing parameters and
guidelines for claims for reimbursement. The Department of Finance has not yet
determined whether to seek judicial review of the Commission's decision.

  The State is involved in a lawsuit related to contamination at the
Stringfellow toxic waste site. In United States, People of the State of
California v. J.B. Stringfellow, Jr., et al., the State is seeking recovery for
post costs of cleanup of the site, a declaration that the defendants are
jointly and severally liable for future costs, and an injunction ordering
completion of the cleanup. However, the defendants have filed a counterclaim
against the State for alleged negligent acts, resulting in significant findings
of liability against the State as owner, operator, and generator of wastes
taken to the site. The State has appealed the rulings. Present estimates of the
cleanup range from $400 million to $600 million.

  The State is a defendant in a coordinated action involving 3,000 plaintiffs
seeking recovery for damages caused by the Yuba River flood of February 1986.
The appellate court affirmed the trial court finding of liability in inverse
condemnation and awarded damages of $500,000 to 12 sample plaintiffs. Potential
liability to the remaining 300 plaintiffs, from claims filed, ranges from $800
million to $1.5 billion. In 1992, the State and plaintiffs filed appeals. In
August 1999, the court of appeal issued a decision reversing the trial court's
judgment against the State and remanding the case for retrial on the inverse
condemnation cause of action.

  On June 24, 1998, plaintiffs in Howard Jarvis Taxpayers Association et al. v.
Kathleen Connell filed a complaint for certain declaratory and injunctive
relief challenging the authority of the State Controller to make payments from
the State Treasury in the absence of a state budget. On July 21, 1998, the
trial court issued a preliminary
                                      C-9
<PAGE>

injunction prohibiting the State Controller from paying moneys from the State
Treasury for fiscal year 1998-99, with certain limited exceptions, in the
absence of a state budget. The preliminary injunction, among other things,
prohibited the State Controller from making any payments pursuant to any
continuing appropriation.

  On July 22 and 27, 1998, various employee unions which had intervened in the
case appealed the trial court's preliminary injunction and asked the Court of
Appeal to stay the preliminary injunction. On July 28, 1998, the Court of
Appeal granted the unions' requests and stayed the preliminary injunction
pending the Court of Appeal's decision on the merits of the appeal. On August
5, 1998, the Court of Appeal denied the plaintiffs' request to reconsider the
stay. Also on July 22, 1998, the State Controller asked the California Supreme
Court to immediately stay the trial court's preliminary injunction and to
overrule the order granting the preliminary injunction on the merits. On July
29, 1998, the Supreme Court transferred the State Controller's request to the
Court of Appeal. The matters are now pending before the Court of Appeal. Briefs
are being submitted; no date has yet been set for oral argument.

California Taxes--

  In the opinion of Messrs. Brown & Wood LLP, special California counsel on
California tax matters, under existing law:

    The California Trust will not be treated as an association taxable as a
  corporation. Accordingly, interest on Bonds received by the California
  Trust that is exempt from personal income taxes imposed by or under the
  authority of the State of California will be treated for California income
  tax purposes in the same manner as if received directly by the Unit
  Holders.

    Each Unit Holder of the California Trust will recognize gain or loss when
  the California Trust disposes of a Bond (whether by sale, exchange,
  redemption or payment at maturity) or upon the Unit Holder's sale or other
  disposition of a Unit. The amount of gain or loss for California income tax
  purposes will generally be calculated pursuant to the Code, certain
  provisions of which are incorporated by reference under California law.

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

                                      C-10
<PAGE>


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 years 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,

                                      C-11
<PAGE>


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 from 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.
                                      C-12
<PAGE>


  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

                                      C-13
<PAGE>


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 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. Saul, Ewing, Remick & Saul LLP, 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. 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

                                      C-14
<PAGE>


  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. 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.

New York Trust

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

  Economic Trends. Over the long term, the State of New York (the "State") and
the City of New York (the "City") face serious economic problems. The City
accounts for approximately 41% of the State's population and personal income,
and the City's financial health affects the State in numerous ways. The State
historically has been one of the wealthiest states in the nation. For decades,
however, the State has grown more slowly than the nation as a whole, gradually
eroding its relative economic affluence. Statewide, urban centers have
experienced significant changes involving migration of the more affluent to the
suburbs and an influx of generally less affluent residents. Regionally, the
older Northeast cities have suffered because of the relative success that the
South and the West have had in attracting people and business. The City has
also had to face greater competition as other major cities have developed
financial and business capabilities which make them less dependent on the
specialized services traditionally available almost exclusively in the City.

  The State has for many years had a very high State and local tax burden
relative to other states. The State and its localities have used these taxes to
develop and maintain their transportation networks, public schools and
colleges, public health systems, other social services and recreational
facilities. Despite these benefits, the burden of State and local taxation, in
combination with the many other causes of regional economic dislocation, has
contributed to the decisions of some businesses and individuals to relocate
outside, or not locate within, the State.

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

  New York City. The City, with a population of approximately 7.4 million, is
an international center of business and culture. Its non-manufacturing economy
is broadly based, with the

                                      C-15
<PAGE>

banking and securities, life insurance, communications, publishing, fashion
design, retailing and construction industries accounting for a significant
portion of the City's total employment earnings. Additionally, the City is the
nation's leading tourist destination. The City's manufacturing activity is
conducted primarily in apparel and printing.

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

  As required by law, the City prepares a four-year annual financial plan,
which is reviewed and revised on a quarterly basis and which includes the
City's capital, revenue and expense projections and outlines proposed gap-
closing programs for years with projected budget gaps. The City's current
financial plan projects a surplus in the 1999 and 2000 fiscal years, before
discretionary transfers, and budget gaps for each of the 2001, 2002 and 2003
fiscal years. This pattern of current year surplus operating results and
projected subsequent year budget gaps has been consistent through the entire
period since 1982, during which the City has achieved surplus operating
results, before discretionary transfers, for each fiscal year.

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

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

  Implementation of the Financial Plan is dependent upon the City's ability to
market its securities successfully. The City's financing program for fiscal
years 1999 through 2003 contemplates the issuance of $10.091 billion of general
obligation bonds and $5.340 billion of bonds to be issued by the New York City
Transitional Finance Authority (the "Finance Authority") to finance City
capital projects. In addition, it is currently expected that approximately $2.8
billion of bonds will be issued by the Tobacco Settlement Asset Securitization
Corporation ("TSASC") and paid from revenues received pursuant to a settlement
of litigation with the leading cigarette companies. The Finance Authority and
TSASC were created as part of the City's effort to assist in keeping the City's
indebtedness within the forecast level of the constitutional restrictions on
the amount of debt the City is authorized to incur. If TSASC is not able to
issue bonds in the amount expected, the City will need to find another source
of financing or substantially curtail or halt its capital program. In addition,
the City issues revenue and tax anticipation notes to finance its seasonal
working capital
                                      C-16
<PAGE>

requirements. The success of projected public sales of City bonds and notes,
New York City Municipal Water Finance Authority ("Water Authority") bonds and
Finance Authority bonds will be subject to prevailing market conditions. The
City's planned capital and operating expenditures are dependent upon the sale
of its general obligation bonds and notes, and the Water Authority, Finance
Authority and TSASC bonds. Future developments concerning the City and public
discussion of such developments, as well as prevailing market conditions, may
affect the market for outstanding City general obligation bonds and notes.

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

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

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

  Changes since adoption of the City's Expense Budget for the 1999 fiscal year
in June 1998, prior to the financial plan submitted to the Control Board on
June 26, 1998, include: (i) an increase in projected tax revenues of $976
million, $813 million, $558 million, $174 million and $1.4 billion in fiscal
years 1999 through 2003, respectively; (ii) $300 million, $250 million, $300
million and $300 million of projected resources in fiscal years 2000 through
2003, respectively, from the receipt by the City of funds from the settlement
of litigation with the leading cigarette companies; (iii) a reduction in the
assumed collection of $350 million of projected rent payments for the City's
airports to $210 million and a delay in the receipt of such payments from
fiscal year 2000 to fiscal year 2001; (iv) anticipated proceeds from the
proposed sale of the Coliseum in fiscal year 2001 totaling $345 million; and
(v) net increases in spending of $638 million, $691 million, $679 million and
$1.0 billion in fiscal years 2000 through 2003, including spending for
Medicaid, education initiatives, anti-smoking programs, employee fringe benefit
costs, and other agency programs. The 1999 Modification and the 2000-2003
Financial Plan includes a proposed discretionary transfer in the 1999 fiscal
year of $2.6 billion to pay debt service due in fiscal year 2000, for budget
stabilization purposes, a proposed discretionary transfer in fiscal year 2000
to pay debt service due in fiscal year 2001 totaling $429 million, and a
proposed discretionary transfer in fiscal year 2001 to pay debt service due in
fiscal year 2002 totaling $345 million.

  In addition, the Financial Plan sets forth gap-closing actions to eliminate a
previously projected gap for the 2000 fiscal year and to reduce projected gaps
for fiscal years 2001 through 2003. The gap-closing actions for the 2000
through 2003 fiscal years include: (i) additional agency actions totaling $605
million, $486 million, $409 million and $397 million for fiscal years 2000
through 2003, respectively; (ii) additional Federal aid of $75 million in each
of fiscal years 2000 through 2003, which include the proposed restoration of
$25 million of Federal revenue sharing and $50 million of increased Federal
Medicaid aid; and (iii) additional State actions totaling approximately $125
million in each of fiscal years 2000 through 2003,
                                      C-17

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

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

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

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

  New York State and its Authorities. The State ended the 1998-1999 fiscal year
in balance on a cash basis for the 1998-1999 fiscal year, with a reported
closing balance in the General Fund of $892 million, after reserving a
projected $1.8 billion surplus for use in future years. The Governor's
Executive Budget projects balance on a cash basis for the 1999-2000 fiscal
year, with a closing balance in the General Fund of $2.5 billion, including a
projected reserve of $1.79 billion for use in fiscal years 2000-2001 and 2001-
2002. Subsequently, as a result of revisions to national and State economic
forecasts, the State Division of the Budget has revised its estimate of
receipts for the 1999-2000 fiscal year to include an additional $150 million in
receipts. The Legislature and the State Comptroller will review the Governor's
Executive Budget and are expected to comment on it. The State Assembly and the
State Senate have each adopted budget resolutions which provide an outline of
intended spending and revenue changes to the 1999-2000 Executive Budget which,
the Division of the Budget
                                      C-18
<PAGE>

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

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

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

  Litigation. A number of court actions have been brought involving State
finances. The court actions in which the State is a defendant generally
involve State programs and miscellaneous tort, real property, and contract
claims. While the ultimate outcome and fiscal impact, if any, on the State of
those proceedings and claims are not currently predictable, adverse
determinations in certain of them might have a material adverse effect upon
the State's ability to carry out the 1999 Modification and 2000-2003 Financial
Plan. The City has estimated that its potential future liability on account of
outstanding claims against it as of June 30, 1998 amounted to approximately
$3.5 billion.

New York Taxes--

  In the opinion of bond counsel delivered on the dates the Bonds were issued
(or in opinions to be delivered, in the case of when issued Bonds) the
interest on the Bonds is exempt from New York State and City personal income
taxes, except where such interest is subject to Federal income taxes, as is
described in "Taxes".

  In the opinion of Battle Fowler LLP, special counsel for the Sponsor, under
existing New York law:

    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 the
  Trust will be treated as the income of the Holders in the same manner as
  for Federal income tax purposes. Accordingly, each Holder will be
  considered to have received the interest on its pro rata portion of each
  Bond when interest on the Bond is received by the Trust (or on earlier
  accrual, depending on the Holder's method of accounting and depending on
  the existence of any original issue discount). A noncorporate Holder who is
  a New York State (and City) resident will be subject to New York State (and
  City) personal income taxes on any gain or market discount income
  recognized when it disposes of all or part of its pro rata portion of a
  Bond. A noncorporate Holder who is not a New York State resident will not
  be subject to New York State or City personal income taxes on any gain or
  market discount income recognized when it disposes of all or

                                     C-19
<PAGE>

  part of its pro rata portion of a Bond unless such Units are attributable
  to a business, trade, profession or occupation carried on in New York. A
  New York State (and City) resident should determine its tax basis for its
  pro rata portion of each Bond for New York State (and City) income tax
  purposes in the same manner as for Federal income tax purposes. Interest
  income on, as well as any gain recognized on the disposition of, a Holder's
  pro rata portion of the Bonds is generally not excludable from income in
  computing New York State and City franchise taxes on corporations or
  financial institutions.

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 1999 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 California and filing a Joint Return with $53,000 in taxable income
for the 1999 tax year would need a taxable investment yielding 9.06% 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 1999 Federal income tax rates and 1999
    California income tax rates.
  2 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 $126,600, 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. However, 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 $189,950 for
    married taxpayers filing a joint tax return and $126,600 for single
    taxpayers. The effect of this phase out is not reflected in the above
    table.
  3 Interest earned on municipal obligations may be subject to the federal
    alternative minimum tax. The effect of this provision is not included
    into the above table.
  4 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 rates applicable to the income levels indicated
    within each bracket.
  5 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.

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
    (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 $126,600, 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 effective Federal tax rates. 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 $189,950 for married
    taxpayers filing a joint tax return and $126,600 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. The effect of 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 rates applicable to the income levels indicated
    within each bracket.

  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.

 Re: Tax Exempt Securities Trust, California Trust 173, Maryland Trust 110 and
     New York Trust 177

Dear Sirs:

  We have acted as special counsel for Salomon Smith Barney Inc. as Depositor,
Sponsor and Principal Underwriter (the "Depositor") of Tax Exempt Securities
Trust, California Trust 173, Maryland Trust 110 and New York Trust 177
(collectively, the "Trusts") in connection with the deposit of securities (the
"Securities") therein pursuant to the Trust Agreements referred to below, by
which the Trusts were created and under which the units of fractional
undivided interest (collectively, the "Units") have been issued. Pursuant to
the Trust Agreements the Depositor has transferred to the Trusts certain long-
term bonds and contracts to purchase certain long-term bonds together with
irrevocable letters of credit to be held by the Trustee upon the terms and
conditions set forth in the Trust Agreements. (All bonds to be acquired by the
Trusts are collectively referred to as the "Bonds".)

  In connection with our representation, we have examined the originals or
certified copies of the following documents relating to the creation of the
Trusts, the deposit of the Securities and the issuance and sale of the Units:
(a) the Trust Indenture and Agreement dated July 16, 1987 and the Reference
Trust Agreements of even date herewith relating to each Trust (collectively,
the "Trust Agreements") among the Depositor, The Chase Manhattan Bank as
Trustee, and Kenny S&P Evaluation Services, as Evaluator; (b) the Closing
Memorandum relating to the deposit of the Securities in the Trusts; (c) the
Notification of Registration on Form N-8A and the Registration Statement on
Form N-8B-2, as amended, relating to the Trusts, as filed with the Securities
and Exchange Commission (the "Commission") pursuant to the Investment Company
Act of 1940 (the "1940 Act"); (d) the Registration Statements on Form S-6
(Registration Nos. 333-90615, 333-83479 and 333-90629 (filed with the
Commission pursuant to the Securities Act of 1933 (the "1933 Act"), and
Amendment No. 1 thereto (said Registration Statements, as amended by said
Amendment No. 1 being herein called the "Registration Statement"); (e) the
proposed form of final prospectus (the "Prospectus") relating to the Units,
which is expected to be filed with the Commission this day; (f) resolutions of
the Executive Committees of the Depositor authorizing the execution and
delivery by the Depositor of the Trust Agreements and the consummation of the
transactions contemplated thereby; (g) the Certificates of Incorporation and
By-laws of the Depositor, each certified to by an authorized officer of the
Depositor as of a recent date; (h) a certificate of an authorized officer of
the Depositor with respect to certain factual matters contained therein
("Officers Certificate"); and (i) certificates or telegrams of public
officials as to matters set forth upon therein.

  We have assumed the genuineness of all agreements, instruments and documents
submitted to us as originals and the conformity to originals of all copies
thereof submitted to us. We have also assumed the genuineness of all
signatures and the legal capacity of all persons executing agreements,
instruments and documents examined or relied upon by us.

  Where matters are stated to be "to the best of our knowledge" or "known to
us," our knowledge is limited to the actual knowledge of those attorneys in
our office who have performed services for the Trust, their review of
documents provided to us by the Depositor in connection with this engagement
and inquiries of officers of the Depositor, the results
<PAGE>

of which are reflected in the Officers Certificate. We have not independently
verified the accuracy of the matters set forth in the written statements or
certificates upon which we have relied. We have not reviewed the financial
statements, compilation of the Bonds held by the Trusts, or other financial or
statistical data contained in the Registration Statement and the Prospectus,
as to which we understand you have been furnished with the reports of the
accountants appearing in the Registration Statement and the Prospectus. In
addition, we have made no specific inquiry as to whether any stop order or
investigatory proceedings have been commenced with respect to the Registration
Statement or the Depositor nor have we reviewed court or governmental agency
dockets.

  We have relied without independent investigation upon the opinion dated the
date hereof of Brown & Wood, 555 California Street, San Francisco, Ca. 94104;
and Saul, Ewing, Remick & Saul LLP, 100 South Charles Street, Baltimore,
Maryland 21201-2773 delivered to the Depositor with respect to the questions
of law of the States of California, Florida and New Jersey and with respect to
any disclosure contained in the Registration Statement concerning risk factors
relating to the Bonds of California Trust 173 and Maryland Trust 110,
respectively.

  Statements in this opinion as to the validity, binding effect and
enforceability of agreements, instruments and documents are subject: (i) to
limitations as to enforceability imposed by bankruptcy, reorganization,
moratorium, insolvency and other laws of general application relating to or
affecting the enforceability of creditors' rights, and (ii) to limitations
under equitable principles governing the availability of equitable remedies.

  We are not admitted to the practice of law in any jurisdiction but the State
of New York and we do not hold ourselves out as experts in or express any
opinion as to the laws of other states or jurisdictions except as to matters
of Federal and Delaware corporate law. No opinion is expressed as to the
effect that the law of any other jurisdiction might have upon the subject
matter of the opinions expressed herein under applicable conflicts of law
principles, rules or regulations or otherwise.

  Based on the subject to the foregoing, we are of the opinion that:

  (1) The Trust Agreements have been duly authorized and executed and
delivered by an authorized officer of the Depositor and are valid and binding
obligations of the Depositor in accordance with their respective terms.

  (2) The execution and delivery of the Certificates evidencing the Units has
been duly authorized by the Depositor and such Certificates when executed by
the Depositor and the Trustee in accordance with the provisions of the
Certificates and the respective Trust Agreements and issued for the
consideration contemplated therein, will constitute fractional undivided
interests in the respective Trusts, will be entitled to the benefits of the
respective Trust Agreements, and will conform in all material respects to the
description thereof contained in the Prospectus under the caption heading
"Rights of Unit Holders--Certificates". Upon payment of the consideration for
the Units as provided in the Trust Agreements and the Registration Statement,
the Units will be fully paid and non-assessable by the Trusts.

  We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name in the Registration
Statement and in the Prospectus under the headings "Taxes" and "Legal
Opinion". This opinion is intended solely for the benefit of the addressee in
connection with the issuance of the Units of the Trust and may not be relied
upon in any other manner or by any other person without our express written
consent.

                                          Very truly yours,

             Re:  Tax Exempt Securities Trust, California Trust 173

Ladies and Gentlemen:

  You have requested our opinion as to certain California personal income tax
issues relating to California Trust 173 (the "California Trust") of the Tax
Exempt Securities Trust (the "Trust") sponsored by Salomon Smith Barney Inc.
Our opinion relates solely to the California tax matters described herein. It
is our understanding that Battle Fowler LLP has rendered an opinion, effective
as of the date hereof, as to certain federal income tax matters pertaining to
the Trust.

  In rendering our opinion, we have examined and relied upon, among other
things, (1) the Form S-6 Registration Statement, as filed with the Securities
and Exchange Commission on November 9, 1999 (the "Registration Statement"),
pursuant to which you will offer to a limited number of investors (the "Unit
Holders") the opportunity to purchase fractional undivided interests in the
Trust ("Units"); (2) a copy of the Trust Indenture and Agreement, dated July
16, 1987, among Smith Barney, Harris Upham & Co. Incorporated, Kidder, Peabody
& Co. Incorporated, Drexel Burnham Lambert Incorporated, and L.F. Rothschild &
Co. Incorporated, as Depositors, United States Trust Company of New York, as
Trustee, and Standard & Poor's Corporation as Evaluator; (3) a draft of the
Reference Trust Agreement for the Tax Exempt Securities Trust, California Trust
173, dated November 30, 1999, among Salomon Smith Barney Inc., as Depositor
(the "Depositor"), The Chase Manhattan Bank, as Trustee (the "Trustee"), and
Kenny S&P Evaluation Services, a business unit of J.J. Kenny Company, Inc., a
subsidiary of The McGraw-Hill Companies, Inc., as Evaluator (the "Evaluator"),
incorporating by reference the aforementioned Trust Indenture and Agreement and
amending and supplementing the same (said Trust Indenture and Agreement and
Reference Trust Agreement being herein referred to collectively as the "Trust
Agreement"); and (4) the opinion of Battle Fowler LLP, effective as of the date
hereof, that (i) the California Trust is not an association taxable as a
corporation for federal income tax purposes, and income received by the
California Trust will be treated as the income of the Unit Holders; and (ii)
each Unit Holder of the California Trust will be considered the owner of a pro
rata portion of each Bond in the California Trust under the grantor trust rules
of Sections 671-679 of the Internal Revenue Code of 1986, as amended (the
"Code") such that each Unit Holder of the California Trust will be considered
to have received his or her pro rata share of interest on each Bond (which in
the opinion of bond counsel for each such Bond is excludable from gross income
for Federal income tax purposes) when received by the California Trust. Except
as otherwise defined herein, capitalized terms used herein shall have the
respective meanings ascribed to them in the Registration Statement.

  The Trust consists of separate unit investment trusts designated the
California Trust and other named state trusts (each trust individually referred
to as a "State Trust" and collectively referred to as the "State Trusts"). Each
State Trust was created under the laws of the State of New York pursuant to the
Trust Agreement. Each State Trust will be administered in accordance with the
Trust Agreement as a distinct entity with separate certificates, expenses,
books and records, and the assets of one State Trust may not be commingled with
the assets of any other.

Salomon Smith Barney Inc.

  The Bonds deposited in the California Trust are certain interest-bearing
obligations of the State of California or of the cities, counties and other
political subdivisions thereof, or of the Territory of Guam or the Commonwealth
of Puerto Rico. The Bonds will be held by the Trustee upon the terms and
conditions set forth in the Trust Agreement. You have advised us, and we have
relied upon the fact that, in the opinion of bond counsel to each issuer of
Bonds delivered at the time of their respective issuance, the interest on the
Bonds held in the California Trust is excludable from gross income for federal
income tax purposes and exempt from State of California personal income taxes.
We have made no independent investigation to verify the accuracy of such
conclusions and we express no opinion with respect thereto.

  Under the terms and conditions of the Trust Agreement, once the original
corpus of the California Trust is acquired, the California Trust will have a
fixed portfolio of Bonds. The Trustee will not have the power to vary the
investment of the California Trust nor the power to take advantage of market
variations to improve a Unit Holder's investment, and the Trustee will have no
discretion to retain and reinvest the income or principal of the California
Trust.

  Based on the foregoing, under existing California law applicable to
individuals who are California residents, we are of the opinion that:

    1. The California Trust will not be treated as an association taxable as
  a corporation. Accordingly, interest on Bonds received by the California
  Trust that is exempt from personal income taxes imposed by or under the
  authority of the State of California will be treated for California income
  tax purposes in the same manner as if received directly by the Unit
  Holders.

    2. Each Unit Holder of the California Trust will recognize gain or loss
  when the California Trust disposes of a Bond (whether by sale, exchange,
  redemption or payment at maturity) or upon the Unit Holder's sale or other
  disposition of a Unit. The amount of gain or loss for California income tax
  purposes will generally be calculated pursuant to the Code, certain
  provisions of which are incorporated by reference under California law.

  We have not addressed, nor are we opining on, any federal income tax aspects
relating to the California Trust and, other than as specifically set forth
herein, we have not addressed, nor are we opining on, any state or local tax
aspects relating to the California Trust.

  We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement under the Securities Act of 1933, as amended, covering
the issuance of Units in the California Trust, and to the reference to our firm
in the Registration Statement under the heading "California Trust -- California
Taxes."

  This letter is furnished by us solely for your benefit, and the benefit of
The Chase Manhattan Bank, as Trustee for the California Trust, in connection
with the Registration Statement for the public offering of interests in the Tax
Exempt Securities Trust, and this letter may not be relied upon by any other

              Re: Tax Exempt Securities Trust, Maryland Trust 110

Ladies and Gentlemen:

  We have acted as special Maryland counsel to you as Sponsors (the
"Sponsors") and trustee of the above-referenced tax-exempt securities trust
(the "Trust"), which includes an individual trust (the "Maryland Trust")
holding certain bonds and other securities (the "Bonds"). You have asked that
we, acting in such capacity, render an opinion to you with respect to certain
matters relating to the tax treatment under the laws of Maryland of the
Maryland Trust and of the units of fractional undivided interest in the
Maryland Trust (the "Units") to be issued pursuant to the Registration
Statement (No. 333-83479) on Form S-6 filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Registration
Statement").

  As a basis for our opinions, we have examined such provisions of Maryland
law as we considered relevant. We are relying on the opinions of Battle
Fowler, LLP, special counsel to the Sponsors, as to the federal income tax
consequences of an investment in the Trust.

  Each Unit represents a fractional undivided interest in the Maryland Trust.
In the opinion of Battle Fowler, LLP, for federal income tax purposes:

    (a) the Maryland Trust is not an association taxable as a corporation;

    (b) a holder of units ("Holder") is considered the owner of a pro rata
  portion of each Bond in the Maryland Trust under the grantor trust rules of
  Sections 671-678 of the Internal Revenue Code of 1986, as amended;

    (c) a Holder will be considered to have received the interest on such
  Holder's pro rata portion of each Bond when interest on the Bond is
  received by the Maryland Trust;

    (d) a Holder will recognize taxable gain or loss when all or part of such
  Holder's pro rata portion of a Bond in the Maryland Trust is disposed of
  (whether by sale, exchange, redemption, or payment at maturity) or when the
  Holder redeems or sells such Holder's units.

  It is our understanding and the following opinions assume, that the Maryland
Trust will have no income other than interest income on the Bonds including,
when earned or received, any amount attributable to original issue discount
which is treated as interest income for federal income tax purposes and gain
on the disposition of the Bonds.

  In general, it is noted that under the terms of the Maryland statutes which
authorize the issuance of bonds of the State of Maryland, its political
subdivisions and authorities, the Bonds, the income therefrom and any profit
made on the sale or sale thereof shall at all times be free from taxation of
every kind by the State of Maryland and by the municipalities and all other
political divisions of the State of Maryland; in general, those statutes do
not refer to estate or inheritance taxes or franchise taxes on financial
institutions which are measured by net earnings or any other taxes not levied
or assessed directly on those bonds, their transfer or the income therefrom.

  Based in part, upon our understanding that the Maryland Trust consists of
Bonds issued by the State of Maryland, the Government of Puerto Rico, the
Government of Guam and their respective political subdivisions and
authorities; and that, in the opinion of bond counsel the interest on the
Bonds will be excluded form gross income for federal income tax purposes
(except in certain circumstances referred to in the Prospectus), Saul, Ewing,
Remick & Saul LLP, special Maryland counsel for this trust are the opinion
that for Maryland State and local tax purposes:

    1. 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 measured by net earnings. The
  Maryland Trust is not subject to Maryland property taxes imposed on the
  intangible personal property of certain corporations.

    2. Except as described below is 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 or obligations of the
  State of Maryland, the Government of Puerto Rico, or the Government of Guam
  and their respective political subdivisions and authorities. Interest on
  Bonds is not subject to the Maryland Franchise Tax imposed on "financial
  institutions."

    3. 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.

    4. 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 rate 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. Gain 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. Profits realized on the sale or
  exchange of Bonds are not subject to the Maryland Franchise Tax imposed on
  "financial institutions."

    5. Units of the Maryland Trust will be subject to Maryland inheritance
  and estate tax only if held by Maryland residents.

    6. Neither the Bonds nor the Units will be subject to Maryland personal
  property tax.

    7. The sales of Units in Maryland or the holder of Units in Maryland will
  not be subject to Maryland Sales or Use Tax.

  At your request, we have also reviewed certain official statements relating
to Bonds of the State of Maryland and certain of its subdivisions, agencies or
instrumentalities available to us as of this date with respect only to general
risk factors relating to such Bonds. We have not reviewed each official
statement relating to each of the Bonds included in the Maryland Trust. We
have neither reviewed the accuracy or completeness of, or otherwise verified,
the information

contained in those official statements nor have we reviewed any risk factors
which are discussed in the Prospectus other than those relating specifically
to Bonds issued by the State of Maryland, its political subdivisions and their
respective authorities. Based solely upon the review described above, we
confirm that, in our opinion, (i) the materials in the Prospectus under "State
Risks Factors; neither contain any untrue statement of, nor omit to state a
material fact included in, any of the official statements we have reviewed
with respect to Maryland and (ii) the summary of matters of Maryland law
contained in the Prospectus under "Taxes" is accurate. We hereby consent to
the reference to this firm in the Prospectus comprising a part of the
Registration Statement and we consent to the filing of this opinion as an
exhibit to the Registration Statement.
