MUNICIPAL INVESTMENT          This Defined Fund consists of separate underlying
TRUST FUND                    Trusts designated as the Florida, New York and
- ------------------------------Pennsylvania Trusts, each of which is a portfolio
MULTISTATE SERIES - 73        of preselected securities issued by or on behalf
(UNIT INVESTMENT TRUSTS)      of the State for which the Trust is named and
FLORIDA TRUST (INSURED)       political subdivisions and public authorities
5.71%                         thereof or certain United States territories or
  ESTIMATED CURRENT RETURN    possessions. The Fund is formed for the purpose of
  5.81%                       providing interest income which in the opinion of
  ESTIMATED LONG TERM RETURN  counsel is, with certain exceptions, exempt from
NEW YORK TRUST (INSURED)      regular Federal income taxes and from certain
5.85%                         state and local personal income taxes in the State
  ESTIMATED CURRENT RETURN    for which each Trust is named but may be subject
  5.96%                       to other state and local taxes. In addition, the
  ESTIMATED LONG TERM RETURN  Debt Obligations included in each Trust are
PENNSYLVANIA TRUST (INSURED)  insured. This insurance guarantees the timely
5.91%                         payment of principal and interest on but does not
  ESTIMATED CURRENT RETURN    guarantee the market value of the Debt Obligations
  6.01%                       or the value of the Units. As a result of this
  ESTIMATED LONG TERM RETURN  insurance, Units of each Trust are rated AAA by
AS OF OCTOBER 12, 1994        Standard & Poor's Ratings Group, a division of
                              McGraw Hill, Inc. ('Standard & Poor's'). The value
                              of the Units of each Trust will fluctuate with the
                              value of the Portfolio of underlying Debt
                              Obligations in the Trust.
                              The Estimated Current Return and Estimated Long
                              Term Return figures shown give different
                              information about the return to investors.
                              Estimated Current Return on a Unit shows a net
                              annual current cash return based on the initial
                              Public Offering Price and the maximum applicable
                              sales charge and is computed by multiplying the
                              estimated net annual interest rate per Unit by
                              $1,000 and dividing the result by the Public
                              Offering Price per Unit (including the sales
                              charge but not including accrued interest).
                              Estimated Long Term Return shows a net annual
                              long-term return to investors holding to maturity
                              based on the yield on the individual bonds in the
                              Portfolio, weighted to reflect the time to
                              maturity (or in certain cases to an earlier call
                              date) and market value of each bond in the
                              Portfolio, adjusted to reflect the Public Offering
                              Price (including the sales charge) and estimated
                              expenses. Unlike Estimated Current Return,
                              Estimated Long Term Return takes into account
                              maturities of the underlying Securities and
                              discounts and premiums. Distributions of income on
                              Units are generally subject to certain delays; if
                              the Estimated Long Term Return figure shown above
                              took these delays into account, it would be lower.
                              Both Estimated Current Return and Estimated Long
                              Term Return are subject to fluctuations with
                              changes in Portfolio composition (including the
                              redemption, sale or other disposition of
                              Securities in the Portfolio), changes in the
                              market value of the underlying Securities and
                              changes in fees and expenses. Estimated cash flows
                              are available upon request from the Sponsors at no
                              charge.
                              Minimum purchase: 1 Unit.

DEFINED ASSET FUNDSSM is America's oldest and largest family of unit investment
trusts with over $90 billion sponsored since 1970. Each Defined Fund is a
portfolio of preselected securities. The portfolio is divided into 'units'
representing equal shares of the underlying assets. Each unit receives an equal
share of income and principal distributions.
With Defined Asset Funds you know in advance what you are investing in and that
changes in the portfolio are limited. Most defined bond funds pay interest
monthly and repay principal as bonds are called, redeemed, sold or as they
mature. Defined equity funds offer preselected stock portfolios with defined
termination dates.
Your financial advisor can help you select a Defined Fund to meet your personal
investment objectives. Our size and market presence enable us to offer a wide
variety of investments. Defined Funds are available in the following types of
securities: municipal bonds, corporate bonds, government bonds, utility stocks,
growth stocks, even international securities denominated in foreign currencies.
Termination dates are as short as one year or as long as 30 years. Special funds
are available for investors seeking extra features: insured funds, double and
triple tax-free funds, and funds with 'laddered maturities' to help protect
against rising interest rates. Defined Funds are offered by prospectus only.

   (a) The Indentures were signed and the initial deposits were made on the date
of this Prospectus.
   (b) Estimated Current Return represents annual interest income after
estimated annual expenses divided by the maximum public offering price including
maximum applicable sales charge. Estimated Long Term Return is the net annual
percentage return based on the yield on each underlying Debt Obligation weighted
to reflect market value and time to maturity or earlier call date. Estimated
Long Term Return is adjusted for estimated expenses and the maximum offering
price but not for delays in a Trust's distribution of income. Estimated Current
Return shows current annual cash return to investors while Estimated Long Term
Return shows the return on Units held to maturity, reflecting maturities,
discounts and premiums on underlying Debt Obligations. Each figure will vary
with purchase price including sales charge, changes in the net interest income
and the redemptions, sale, or other disposition of Debt Obligations in the
Portfolio.
   (c) Plus accrued interest.
   (d) The Sponsors may create additional Units during the offering period of
the Fund.
   (e) During the initial offering period, the Sponsors intend to offer to
purchase Units at prices based on the offer side value of the underlying
Securities. Thereafter, the Sponsors intend to maintain such a market based on
the bid side value of the underlying Securities which will be equal to the
Redemption Price. (See How To Sell.)
    (f) The sales charge during the initial offering period and in the secondary
market will be reduced on a graduated scale in the case of purchases of 250 or
more Units; the secondary market sales charge will also vary depending on the
maturities of the underlying Securities (see Appendix B). Any resulting
reduction in the Public Offering Price will increase the effective current and
long term returns on a Unit.
   (g) Figure shown represents interest accrued on underlying Securities from
the Initial Date of Deposit to expected date of settlement (normally five
business days after purchase) for Units purchased on Initial Date of Deposit
(see How To Buy--Accrued Interest).
   (h) In the event that any Debt Obligations have a delayed delivery, the
Trustee's Annual Fee and Expenses will be reduced over a period in the amount of
interest that would have accrued on the Debt Obligations between the date of
settlement for the Units and the actual date of delivery of the Debt
Obligations. The Trustee will be reimbursed for this reduction (see Income and
Distributions--Income).

INVESTOR'S GUIDE
MUNICIPAL INVESTMENT          MUNICIPAL INVESTMENT TRUST FUND
TRUST FUND                    Our defined portfolios of municipal bonds offer
- ------------------------------investors a simple and convenient way to earn
Multistate Series             monthly income tax-free. And by purchasing
                              municipal Defined Funds, investors not only avoid
                              the problem of selecting municipal bonds by
                              themselves, but also gain the advantage of
                              diversification by investing in bonds of several
                              different issuers. Spreading your investment among
                              different securities and issuers reduces your
                              risk, but does not eliminate it.
                              MONTHLY TAX-FREE INTEREST INCOME
                              Each Trust pays monthly income, even though the
                              underlying bonds pay interest semi-annually. This
                              income is generally 100% exempt under existing
                              laws from regular federal income tax and from
                              certain state and local personal income taxes in
                              the State for which the Trust is named. Any gain
                              on disposition of the underlying bonds will be
                              subject to tax.
                              REINVESTMENT OPTION
                              You can elect to automatically reinvest your
                              distributions into a separate portfolio of
                              federally tax-exempt bonds. Reinvesting helps to
                              compound your income tax-free. Income from the
                              reinvestment program may be subject to state and
                              local taxes.
                              A-RATED INVESTMENT QUALITY
                              Each bond in the Fund has been selected by
                              investment professionals among available bonds
                              rated A or better by at least one national rating
                              organization or has, in the opinion of Defined
                              Funds research analysts, comparable credit
                              characteristics. Bonds with these 'investment
                              grade' ratings are judged to have a strong
                              capacity to pay interest and repay principal. In
                              addition, units of any insured Fund are rated AAA
                              by Standard & Poor's.
                              PROFESSIONAL SELECTION AND SUPERVISION
                              Each Trust contains a variety of securities
                              selected by experienced buyers and market
                              analysts. The Trusts are not actively managed.
                              However, each portfolio is regularly reviewed and
                              a security can be sold if, in the opinion of
                              Defined Funds analysts and buyers, retaining it
                              could be detrimental to investors' interests.
                              A LIQUID INVESTMENT
                              Although not legally required to do so, the
                              Sponsors have maintained a secondary market for
                              Defined Asset Funds for over 20 years. You can
                              cash in your units at any time. Your price is
                              based on the market value of the bonds in the
                              Fund's portfolio at that time as determined by an
                              independent evaluator. Or, you can exchange your
                              investment for another Defined Fund at a reduced
                              sales charge. There is never a fee for cashing in
                              your investment.
                              PRINCIPAL DISTRIBUTIONS
                              Principal from sales, redemptions and maturities
                              of bonds in the Fund is distributed to investors
                              periodically.
                              RISK FACTORS
                              Unit price fluctuates and is affected by interest
                              rates as well as the financial condition of the
                              issuers and insurers of the bonds.

To compare the yield of a taxable security with the yield of a tax-free security
find your taxable income and read across. These tables incorporate current
Federal and applicable State (and City) income tax rates and assume that all
income would otherwise be taxable at the investor's highest tax rates. Yield
figures are for example only.
 
Legislation has recently been enacted that would increase rates for certain
individuals, thereby increasing the tax-free equivalent yield.
 
*Based upon net amount subject to Federal income tax after deductions and
exemptions. These tables do not reflect other possible tax factors such as the
alternative minimum tax, personal exemptions, the phase out of exemptions,
itemized deductions and the possible partial disallowance of deductions.
Consequently, holders are urged to consult their own tax advisers in this
regard.

     Minimum of $5.00 (see Income and Distributions--Fund Expenses)
MANDATORY TERMINATION DATE
     Each Trust must be terminated no later than one year after the maturity
     date of the last maturing Debt Obligation listed under its Portfolio (see
     Portfolios).
MINIMUM VALUE OF TRUSTS
     Any Trust may be terminated if its value is less than 40% of the Face
     Amount of Securities in the Portfolio on the date of their deposit.

     OBJECTIVE--To provide tax-exempt interest income through investment in
fixed-income debt obligations issued by or on behalf of the States for which the
Trusts are named and political subdivisions and public authorities thereof or
certain United States territories or possessions. There is no assurance that
this objective will be met because it is subject to the continuing ability of
issuers of the Debt Obligations held by the Trusts to meet their principal and
interest requirements. Furthermore, the market value of the underlying Debt
Obligations, and therefore the value of the Units, will fluctuate with changes
in interest rates and other factors.
 
     RISK FACTORS--Investment in a Trust should be made with an understanding
that the value of the underlying Portfolio may decline with increases in
interest rates. In recent years there have been wide fluctuations in interest
rates and thus in the value of fixed-rate debt obligations generally. The
Sponsors cannot predict whether these fluctuations will continue in the future.
The Securities are generally not listed on a national securities exchange.
Whether or not the Securities are listed, the principal trading market for the
Securities will generally be in the over-the-counter market. As a result, the
existence of a liquid trading market for the Securities may depend on whether
dealers will make a market in the Securities. There can be no assurance that a
market will be made for any of the Securities, that any market for the
Securities will be maintained or of the liquidity of the Securities in any
markets made. In addition, the Fund may be restricted under the Investment
Company Act of 1940 from selling Securities to any Sponsor. The price at which
the Securities may be sold to meet redemptions and the value of Trust Units will
be adversely affected if trading markets for the Securities are limited or
absent.
 
   
     PUBLIC OFFERING PRICE--During the initial offering period and any offering
of additional units the Public Offering Price of the Units of a Trust is based
on the aggregate offer side evaluation of the underlying Securities in the Trust
(the price at which they could be directly purchased by the public assuming they
were available) divided by the number of Units of the Trust outstanding plus the
applicable sales charge (as set forth on page A-3.)(b) For secondary market
sales charges see Appendix B. Units are offered at the Public Offering Price
computed as of the Evaluation Time for all sales made subsequent to the previous
evaluation, plus cash per unit in the Capital Account not allocated to the
purchase of specific Securities and net interest accrued. The Public Offering
Price on the Initial Date of Deposit and subsequent dates will vary from the
Public Offering Prices set forth on pages A-3 and A-5. (See How To Buy; How To
Sell.)
 
     ESTIMATED CURRENT RETURN; ESTIMATED LONG TERM RETURN--Estimated Current
Return on a Unit of the Trust shows the return based on the Initial Public
Offering Price and the maximum applicable sales charge (as set forth on page
A-3) and is computed by multiplying the estimated net annual interest rate per
Unit (which shows the return per Unit based on $1,000 face amount per Unit) by
$1,000 and dividing the result by the Public Offering Price per Unit (not
including accrued interest). Estimated Long Term Return on a Unit of the Trust
shows a net annual long-term return to investors holding to maturity based on
the individual Debt Obligations in the Portfolio weighted to reflect the time to
maturity (or in certain cases to an earlier call date) and market value of each
Debt Obligation in the Portfolio, adjusted to reflect the Public Offering Price
(including the maximum applicable sales charge) and estimated expenses. The net
annual interest rate per Unit and the net annual long-term return to investors
will vary with changes in the fees and expenses of the Trustee and Sponsors and
the fees of the Evaluator which are paid by the Fund, and with the exchange,
redemption, sale, prepayment or maturity of the underlying Securities; the
Public Offering Price will vary with any reduction in sales charges paid in the
case of purchases of 250 or more Units, as well as with fluctuations in the
offer side evaluation of the underlying Securities. Therefore, it can be
expected that the Estimated Current Return and Estimated Long Term Return will
fluctuate in the future (see Income and Distributions--Returns).
    
 
- ---------------
(a) In addition to this amount, the Sponsors may be reimbursed for bookkeeping
or other administrative expenses not exceeding their actual costs, currently at
a maximum annual rate of $0.10 per Unit.
(b) The sales charge during the initial offering period and in the secondary
market will be reduced on a graduated scale in the case of purchases of 250 or
more Units (see Appendix B).

INVESTMENT SUMMARY FOR EACH TRUST AS OF OCTOBER 12, 1994 (CONTINUED)
    
 
     MONTHLY DISTRIBUTIONS--Monthly distributions of interest and any principal
or premium received by a Trust will be made in cash on or shortly after the 25th
day of each month to Holders of record of Units of the Trust on the 10th day of
such month commencing with the first distribution on the date indicated above
(see Income and Distributions). Alternatively, Holders may elect to have their
monthly distributions reinvested in the Municipal Fund Accumulation Program,
Inc. Further information about the program, including a current prospectus, may
be obtained by returning the enclosed form (see Income and
Distributions--Investment Accumulation Program).
 
     TAXATION--In the opinion of special counsel to the Sponsors, each Holder of
Units of a Trust will be considered to have received the interest on his pro
rata portion of each Debt Obligation in the Trust when interest on the Debt
Obligation is received by the Trust. In the opinion of bond counsel rendered on
the date of issuance of the Debt Obligation, this interest is exempt under
existing law from regular Federal income tax and exempt from certain state and
local personal income taxes of the State for which the Trust is named (except in
certain circumstances depending on the Holder), but may be subject to other
state and local taxes. Any gain on the disposition of a Holder's pro rata
portion of a Debt Obligation will be subject to tax. (See Taxes.)
 
     MARKET FOR UNITS--The Sponsors, though not obligated to do so, intend to
maintain a secondary market for Units based on the aggregate bid side evaluation
of the underlying Securities. If this market is not maintained a Holder will be
able to dispose of his Units through redemption at prices also based on the
aggregate bid side evaluation of the underlying Securities. There is no fee for
selling Units. Market conditions may cause the prices available in the market
maintained by the Sponsors or available upon exercise of redemption rights to be
more or less than the total of the amount paid for Units plus accrued interest.

The Example assumes reinvestment of all distributions into additional Units of a
Trust (a reinvestment option different from that offered by this Fund--see
Income and Distributions--Investment Accumulation Program) and utilizes a 5%
annual rate of return as mandated by Securities and Exchange Commission
regulations applicable to mutual funds. Cumulative expenses above reflect both
sales charges and operating expenses on an increasing investment (because the
net annual return is reinvested). In addition to the charges described above, a
Holder selling or redeeming his Units in the secondary market (before a Trust
terminates) will receive a price based on the then-current bid side evaluation
of the underlying securities. The difference between this bid side evaluation
and the offer side evaluation (the basis for the Public Offering Price), as of
the day before the Initial Date of Deposit, is $4.00 per Unit for each Trust. Of
course, this difference may change over time. The Example should not be
considered a representation of past or future expenses or annual rate of return;
the actual expenses and annual rate of return may be more or less than those
assumed for purposes of the Example.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Sponsors, Trustee and Holders of Municipal Investment Trust Fund,
Multistate Series - 73, Defined Asset Funds (Florida, New York and Pennsylvania
Trusts):
 
We have audited the accompanying statements of condition, including the
portfolios, of Municipal Investment Trust Fund, Multistate Series - 73, Defined
Asset Funds (Florida, New York and Pennsylvania Trusts) as of October 13, 1994.
These financial statements are the responsibility of the Trustee. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. The deposit on October
13, 1994 of an irrevocable letter or letters of credit for the purchase of
securities, as described in the statements of condition, was confirmed to us by
The Bank of New York, the Trustee. An audit also includes assessing the
accounting principles used and significant estimates made by the Trustee, as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Municipal Investment Trust
Fund, Multistate Series - 73, Defined Asset Funds (Florida, New York and
Pennsylvania Trusts) at October 13, 1994 in conformity with generally accepted

(1) Aggregate cost to each Trust of the Debt Obligations is based on the offer
    side evaluation determined by the Evaluator at the Evaluation Time on the
    business day prior to the Initial Date of Deposit as set forth under How To
    Buy. See also the column headed Cost of Debt Obligations to Trust under
    Portfolios. An irrevocable letter or letters of credit in the aggregate
    amount of $9,333,971.75 has been deposited with the Trustee. The amount of
    such letter or letters of credit includes $9,168,333.00 (equal to the
    aggregate purchase price to the Sponsors) for the purchase of $10,000,000
    face amount of Debt Obligations in connection with contracts to purchase
    Debt Obligations, plus $165,638.75 covering accrued interest thereon to the
    earlier of the date of settlement for the purchase of Units or the date of
    delivery of the Debt Obligations. The letter or letters of credit has been
    issued by San Paolo Bank, New York Branch.

(1)  All ratings are by Standard & Poor's. Any rating followed by '*' is subject
     to submission and review of final documentation. Any rating followed by a
     'p' is provisional and assumes the successful completion of the project
     being financed. (See Appendix A.)
 
(2)  Debt Obligations are first subject to optional redemption (which may be
    exercised in whole or in part) on the dates and at the prices indicated
     under the Optional Refunding Redemptions column in the table. In subsequent
     years Debt Obligations are redeemable at declining prices, but typically
     not below par value. Some issues may be subject to sinking fund redemption
     or extraordinary redemption without premium prior to the dates shown.
 
    Certain Debt Obligations may provide for redemption at par prior or in
    addition to any optional or mandatory redemption dates or maturity, for
    example, if proceeds are not able to be used as contemplated, if the project
     is sold by the owner, if the project is condemned or sold, if the project
     is destroyed and insurance proceeds are used to redeem the Debt
     Obligations, if interest on the Debt Obligations becomes subject to
     taxation, if any related credit support expires prior to maturity and is
     not renewed or substitute credit support not obtained, if, in the case of
     housing obligations, mortgages are prepaid, or in other special
     circumstances.
 
    Sinking fund redemptions are all at par and generally redeem only part of an
    issue. Some of the Debt Obligations have mandatory sinking funds which
    contain optional provisions permitting the issuer to increase the principal
    amount of Debt Obligations called on a mandatory redemption date. The
    sinking fund redemptions with optional provisions may, and optional
    refunding redemptions generally will, occur at times when the redeemed Debt
    Obligations have an offer side evaluation which represents a premium over
    par. To the extent that the Debt Obligations were deposited in the Trust at
     a price higher than the redemption price, this will represent a loss of
     capital when compared with the original Public Offering Price of the Units.
     Monthly distributions will generally be reduced by the amount of the income
     which would otherwise have been paid with respect to redeemed Debt
     Obligations and there will be distributed to Holders any principal amount
     and premium received on such redemption after satisfying any redemption
     requests received by the Trust. The current return and long term return in
     this event may be affected by redemptions. The tax effect on Holders of
     redemptions and related distributions is described under Taxes.
 
   
(3)  Evaluation of Debt Obligations by the Evaluator is made on the basis of
    current offer side evaluation. The offering side evaluation is greater than
     the current bid side evaluation of the Debt Obligations, which is the basis
     on which Redemption Price per Unit is determined (see How To Sell). The
     aggregate value based on the bid side evaluation at the Evaluation Time on
     the business day prior to the Initial Date of Deposit was $3,274,010.00,
     which is $14,000.00 (.40% of the aggregate face amount) lower than the
     aggregate Cost of Debt Obligations to Trust based on the offer side
     evaluation.
    Yield to Maturity on the Initial Date of Deposit of Debt Obligations was
    computed on the basis of the offer side evaluation at the Evaluation Time on
    the business day prior to the Initial Date of Deposit. Percentages in this
     column represent Yield to Maturity on Initial Date of Deposit unless
     followed by '+' which indicates yield to an earlier redemption date. (See
     Income and Distributions--Returns for a description of the computation of
     yield price.)
 
                      ------------------------------------
 
   All Debt Obligations are represented entirely by contracts to purchase such
    Debt Obligations, which were entered into by the Sponsors on October 12,
    1994. All contracts are expected to be settled by the initial settlement
   date for purchase of Units.
    
 
   All Debt Obligations have been insured or guaranteed to maturity by the
    indicated insurance company (see Risk Factors--Obligations Backed by
    Insurance).
 
  +  See Footnote (3).

     this event may be affected by redemptions. The tax effect on Holders of
     redemptions and related distributions is described under Taxes.
 
   
(3)  Evaluation of Debt Obligations by the Evaluator is made on the basis of
    current offer side evaluation. The offering side evaluation is greater than
     the current bid side evaluation of the Debt Obligations, which is the basis
     on which Redemption Price per Unit is determined (see How To Sell). The
     aggregate value based on the bid side evaluation at the Evaluation Time on
     the business day prior to the Initial Date of Deposit was $2,965,522.30,
     which is $13,000.00 (.40% of the aggregate face amount) lower than the
     aggregate Cost of Debt Obligations to Trust based on the offer side
     evaluation.
    Yield to Maturity on the Initial Date of Deposit of Debt Obligations was
    computed on the basis of the offer side evaluation at the Evaluation Time on
    the business day prior to the Initial Date of Deposit. Percentages in this
     column represent Yield to Maturity on Initial Date of Deposit unless
     followed by '+' which indicates yield to an earlier redemption date. (See
     Income and Distributions--Returns for a description of the computation of
     yield price.)
 
                      ------------------------------------
 
   All Debt Obligations are represented entirely by contracts to purchase such
    Debt Obligations, which were entered into by the Sponsors during the period
    October 11, 1994 to October 12, 1994. All contracts are expected to be
   settled by the initial settlement date for purchase of Units.
    
 
   All Debt Obligations have been insured or guaranteed to maturity by the
    indicated insurance company (see Risk Factors--Obligations Backed by
    Insurance).

NOTES
 
(1)  All ratings are by Standard & Poor's. Any rating followed by '*' is subject
     to submission and review of final documentation. Any rating followed by a
     'p' is provisional and assumes the successful completion of the project
     being financed. (See Appendix A.)
 
(2)  Debt Obligations are first subject to optional redemption (which may be
    exercised in whole or in part) on the dates and at the prices indicated
     under the Optional Refunding Redemptions column in the table. In subsequent
     years Debt Obligations are redeemable at declining prices, but typically
     not below par value. Some issues may be subject to sinking fund redemption
     or extraordinary redemption without premium prior to the dates shown.
 
    Certain Debt Obligations may provide for redemption at par prior or in
    addition to any optional or mandatory redemption dates or maturity, for
    example, if proceeds are not able to be used as contemplated, if the project
     is sold by the owner, if the project is condemned or sold, if the project
     is destroyed and insurance proceeds are used to redeem the Debt
     Obligations, if interest on the Debt Obligations becomes subject to
     taxation, if any related credit support expires prior to maturity and is
     not renewed or substitute credit support not obtained, if, in the case of
     housing obligations, mortgages are prepaid, or in other special
     circumstances.
 
    Sinking fund redemptions are all at par and generally redeem only part of an
    issue. Some of the Debt Obligations have mandatory sinking funds which
    contain optional provisions permitting the issuer to increase the principal
    amount of Debt Obligations called on a mandatory redemption date. The
    sinking fund redemptions with optional provisions may, and optional
    refunding redemptions generally will, occur at times when the redeemed Debt
    Obligations have an offer side evaluation which represents a premium over
    par. To the extent that the Debt Obligations were deposited in the Trust at
     a price higher than the redemption price, this will represent a loss of
     capital when compared with the original Public Offering Price of the Units.
     Monthly distributions will generally be reduced by the amount of the income
     which would otherwise have been paid with respect to redeemed Debt
     Obligations and there will be distributed to Holders any principal amount
     and premium received on such redemption after satisfying any redemption
     requests received by the Trust. The current return and long term return in
     this event may be affected by redemptions. The tax effect on Holders of
     redemptions and related distributions is described under Taxes.
 
(3)  Evaluation of Debt Obligations by the Evaluator is made on the basis of
    current offer side evaluation. The offering side evaluation is greater than
     the current bid side evaluation of the Debt Obligations, which is the basis
     on which Redemption Price per Unit is determined (see How To Sell). The
     aggregate value based on the bid side evaluation at the Evaluation Time on
     the business day prior to the Initial Date of Deposit was $3,008,030.00,
     which is $13,000.00 (.40% of the aggregate face amount) lower than the
     aggregate Cost of Debt Obligations to Trust based on the offer side
     evaluation.
    Yield to Maturity on the Initial Date of Deposit of Debt Obligations was
    computed on the basis of the offer side evaluation at the Evaluation Time on
    the business day prior to the Initial Date of Deposit. Percentages in this
     column represent Yield to Maturity on Initial Date of Deposit unless
     followed by '+' which indicates yield to an earlier redemption date. (See
     Income and Distributions--Returns for a description of the computation of
     yield price.)
 
                      ------------------------------------
 
   All Debt Obligations are represented entirely by contracts to purchase such
    Debt Obligations, which were entered into by the Sponsors during the period
    October 11, 1994 to October 12, 1994. All contracts are expected to be

DESCRIPTION OF FUND INVESTMENTS
 
PORTFOLIO SELECTION
 
     Experienced professional buyers and research analysts for Defined Asset
Funds, with information on the markets for suitable securities and on thousands
of issues, selected securities for the Fund's portfolio (the 'Portfolio'),
considering its investment objective and other factors including: (1) the
quality of the Debt Obligations, as evidenced by a rating in the category A or
better by at least one recognized rating organization (see Appendix A) or
comparable credit enhancement or (in the opinion of Defined Asset Funds
research) credit characteristics; (2) yield and price relative to comparable
securities; (3) diversification as to purpose and location of issuer, subject to
availability of suitable debt obligations; and (4) maturities (including call
protection). There is no leverage or borrowing to increase the risk to the Fund,
nor does the Portfolio contain other kinds of securities to enhance yield.
 
     Composition of the Portfolio is summarized under Investment Summary and the
names and certain characteristics of the debt obligations in the Portfolio (the
'Debt Obligations' or the 'Securities') are listed in the financial statements.
 
     Yields on debt obligations depend on factors including general conditions
of the municipal bond market and the general bond markets, size of a particular
offering, and the maturity and rating of the particular issue. Ratings represent
opinions of the rating organizations as to the quality of securities rated, but
these are general (not absolute) standards of quality. Yields can vary among
obligations with similar maturities, coupons and ratings.
 
     Neither the Sponsors nor the Trustee are liable for any default, failure or
defect in a Security. If a contract to purchase any Debt Obligation fails (a
'Failed Debt Obligation'), the Sponsors are authorized to deposit Replacement
Securities which (i) are tax-exempt bonds issued by a state or political
subdivision or a U.S. territory or possession; (ii) have a fixed maturity or
disposition date substantially similar to the Failed Debt Obligation; (iii) are
rated A or better by at least one recognized rating organization or have
comparable credit characteristics; and (iv) are not when, as and if issued.
Replacement Securities must be deposited within 110 days after deposit of the
failed contract, at a cost not exceeding funds reserved for purchasing the
Failed Debt Obligation and at a yield to maturity and current return, as of the
date the failed contract was deposited, substantially equivalent (considering
then current market conditions and relative creditworthiness) to those of the
Failed Debt Obligation.
 
     Because each Defined Fund is a portfolio of preselected securities,
purchasers know in advance what they are investing in. The Portfolio is listed
in the prospectus so that generally the securities, maturities, call dates and
ratings are known when they buy. Of course, the Portfolio changes somewhat over
time as additional Securities are deposited, as Securities are called or
redeemed, or as they are sold to meet redemptions and in the limited
circumstances described below.
 
PORTFOLIO SUPERVISION
 
     The Fund is a unit investment trust which follows a buy and hold investment
strategy. Traditional methods of investment management for mutual funds
typically involve frequent changes in fund holdings based on economic, financial
and market analyses. Because the Fund is not actively managed, it may retain an
issuer's securities despite adverse financial developments. However, Defined
Asset Funds' experienced financial analysts regularly review the Portfolio, and
the Sponsors may instruct the Trustee to sell securities in the following
 
                                       1
<PAGE>
circumstances: (i) default in payment of amounts due on the security; (ii)
institution of certain legal proceedings; (iii) other legal questions or
impediments affecting the security or payments thereon; (iv) default under
certain documents adversely affecting debt service or in payments on other
securities of the same issuer or guarantor; (v) decline in projected income
pledged for debt service on a revenue bond; (vi) if a security becomes taxable
or otherwise inconsistent with the Fund's investment objectives; (vii) a right
to sell or redeem the security pursuant to a guarantee or other credit support;
or (viii) decline in security price or other market or credit factors (including
advance refunding) that, in the opinion of Defined Asset Funds research, makes
retention of the security detrimental to the interests of Holders. If there is a
payment default on any Security and the Agent for the Sponsors fails to instruct
the Trustee within 30 days after notice of the default, the Trustee will sell
the Security.
 
     The Trustee must reject any offer by an issuer of a Debt Obligation to
exchange another security pursuant to a refunding or refinancing plan unless (a)
the Debt Obligation is in default or (b) in the written opinion of Defined Asset
Funds research analysts, a default is probable in the reasonably foreseeable
future, and the Sponsors instruct the Trustee to accept the offer or take any
other action with respect to the offer as the Sponsors consider appropriate.
 
RISK FACTORS
 
     An investment in units of beneficial interest in the Fund ('Units') should
be made with an understanding of the risks which an investment in fixed-rate
debt obligations may entail, including the risk that the value of the Portfolio
and hence of the Units will decline with increases in interest rates. In recent
years there have been wide fluctuations in interest rates and thus in the value
of fixed-rate debt obligations generally. The Sponsors cannot predict future
economic policies or their consequences or, therefore, the course or extent of
any similar fluctuations in the future. To the extent that payment of amounts
due on Debt Obligations depends on revenue from publicly held corporations, an
investor should understand that these Debt Obligations, in many cases, do not
have the benefit of covenants which would prevent the corporations from engaging
in capital restructurings or borrowing transactions in connection with corporate
acquisitions, leveraged buyouts or restructurings, which could have the effect
of reducing the ability of the corporation to meet its obligations and may in
the future result in the ratings of the Debt Obligations and the value of the
underlying Portfolio being reduced.
 
     The Securities are generally not listed on a national securities exchange.
Whether or not the Securities are listed, the principal trading market for the
Securities will generally be in the over-the-counter market. As a result, the
existence of a liquid trading market for the Securities may depend on whether
dealers will make a market in the Securities. There can be no assurance that a
market will be made for any of the Securities, that any market for the
Securities will be maintained or of the liquidity of the Securities in any
markets made. In addition, the Fund may be restricted under the Investment
Company Act of 1940 from selling Securities to any Sponsor. The price at which
the Securities may be sold to meet redemptions and the value of the Fund will be
adversely affected if trading markets for the Securities are limited or absent.
 
     Certain of the Securities in the Fund may have been deposited at a market
discount. Securities trade at less than par value because the interest rates on
the Securities are lower than interest on comparable debt securities being
issued at currently prevailing interest rates. The current returns of securities
trading at a market discount are lower than the current returns of comparably
rated debt securities of a similar type issued at currently prevailing interest
rates because discount securities tend to increase in market value as they
approach maturity and the full principal amount becomes payable. If currently
prevailing interest rates for newly issued and otherwise comparable securities
increase, the market discount of previously issued securities will become deeper
and if currently prevailing interest rates for newly issued comparable
securities decline, the market discount of previously issued securities will be
reduced, other things being equal. Market discount attributable to interest rate
changes does not indicate a lack of market confidence in the issue.
 
     Certain of the Securities in the Fund may have been deposited at a market
premium. Securities trade at a premium because the interest rates on the
Securities are higher than interest on comparable debt securities being issued
at currently prevailing interest rates. The current returns of securities
trading at a market premium are higher than the current returns of comparably
rated debt securities of a similar type issued at currently prevailing interest
rates because premium securities tend to decrease in market value as they
approach maturity when the face amount becomes payable. Because part of the
purchase price is thus returned not at maturity but through current income
payments, an early redemption of a premium security at par will result in a
reduction in yield to the Fund. If currently prevailing interest rates for newly
issued and otherwise comparable securities increase, the market premium of
previously issued securities will decline and if currently prevailing interest
rates for newly
 
                                       2
<PAGE>
issued comparable securities decline, the market premium of previously issued
securities will increase, other things being equal. Market premium attributable
to interest rate changes does not indicate market confidence in the issue.
 
     Holders of Units will be 'at risk' with respect to Securities purchased on
a when, as and if issued basis or for delayed delivery (i.e., either a gain or
loss may result from fluctuations in the offering side evaluation of the
Securities) from the date they commit for Units.
 
     As set forth under Investment Summary and Portfolio, the Fund may contain
or be concentrated in one or more of the types of Debt Obligations discussed
below. An investment in the Fund should be made with an understanding of the
risks that these securities may entail, certain of which are described below. In
addition, investment in a single State Trust, as opposed to a Fund which invests
in the obligations of several states, may involve some additional risk due to
the decreased diversification of economic, political, financial and market
risks. Political restrictions on the ability to tax and budgetary constraints
affecting the state government may result in reductions of, or delays in the
payment of, state aid to cities, counties, school districts and other local
units of government which, in turn, may strain the financial operations and have
an adverse impact on the creditworthiness of these entities. State agencies,
colleges and universities and health care organizations, with municipal debt
outstanding, may also be negatively impacted by reductions in state
appropriations.
 
GENERAL OBLIGATION BONDS
 
     Certain of the Debt Obligations in the Portfolio may be general obligations
of a governmental entity that are secured by the taxing power of the entity.
General obligation bonds are backed by the issuer's pledge of its full faith,
credit and taxing power for the payment of principal and interest. However, the
taxing power of any governmental entity may be limited by provisions of state
constitutions or laws and an entity's credit will depend on many factors,
including an erosion of the tax base due to population declines, natural
disasters, declines in the state's industrial base or inability to attract new
industries, economic limits on the ability to tax without eroding the tax base
and the extent to which the entity relies on Federal or state aid, access to
capital markets or other factors beyond the entity's control.
 
     As a result of the recession's adverse impact upon both revenue and
expenditures, as well as other factors, many state and local governments have
confronted deficits which were the most severe in recent years. Many issuers are
facing highly difficult choices about significant tax increases and/or spending
reductions in order to restore budgetary balance. Failure to implement these
actions on a timely basis could force the issuers to issue additional debt to
finance deficits or cash flow needs.
 
     In addition, certain of the Debt Obligations in the Fund may be obligations
of issuers who rely in whole or in part on ad valorem real property taxes as a
source of revenue. Certain proposals, in the form of state legislative proposals
or voter initiatives, to limit ad valorem real property taxes have been
introduced in various states, and an amendment to the constitution of the State
of California, providing for strict limitations on ad valorem real property
taxes, has had a significant impact on the taxing powers of local governments
and on the financial condition of school districts and local governments in
California. It is not possible at this time to predict the final impact of such
measures, or of similar future legislative or constitutional measures, on school
districts and local governments or on their abilities to make future payments on
their outstanding debt obligations.
 
MORAL OBLIGATION BONDS
 
     The Fund may also include 'moral obligation' bonds. If an issuer of moral
obligation bonds is unable to meet its obligations, the repayment of the bonds
becomes a moral commitment but not a legal obligation of the state or
municipality in question. Even though the state may be called on to restore any
deficits in capital reserve funds of the agencies or authorities which issued
the bonds, any restoration generally requires appropriation by the state
legislature and accordingly does not constitute a legally enforceable obligation
or debt of the state. The agencies or authorities generally have no taxing
power.
 
REFUNDED DEBT OBLIGATIONS
 
      Refunded Debt Obligations 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, however, bonds which were thought to be escrowed to
maturity have been called for redemption prior to maturity.

INDUSTRIAL DEVELOPMENT REVENUE BONDS ('IDRS')
 
     IDRs, including pollution control revenue bonds, are tax-exempt securities
issued by states, municipalities, public authorities or similar entities
('issuers') to finance the cost of acquiring, constructing or improving various
projects, including pollution control facilities and certain manufacturing
facilities. These projects are usually operated by corporations. 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 from receipts or
revenues under arrangements between the issuer and the corporate operator of the
project. These arrangements may be in the form of a lease, installment sale
agreement, conditional sale agreement or loan agreement, but in each case the
payments to the issuer are designed to be sufficient to meet the payments of
amounts due on the IDRs.
 
     IDRs are generally issued under bond resolutions, agreements or trust
indentures pursuant to which the revenues and receipts payable to the issuer by
the corporate operator of the project have been assigned and pledged to the
holders of the IDRs or a trustee for the benefit of the holders of the IDRs. In
certain cases, a mortgage on the underlying project has been assigned to the
holders of the IDRs or a trustee as additional security for the IDRs. In
addition, IDRs are frequently directly guaranteed by the corporate operator of
the project or by an affiliated company. Regardless of the structure, payment of
IDRs is solely dependent upon the creditworthiness of the corporate operator of
the project, corporate guarantor and credit enhancer. Corporate operators or
guarantors that are industrial companies may be affected by many factors which
may have an adverse impact on the credit quality of the particular company or
industry. These include cyclicality of revenues and earnings, regulatory and
environmental restrictions, litigation resulting from accidents or
environmentally-caused illnesses, extensive competition (including that of
low-cost foreign companies), unfunded pension fund liabilities or off-balance
sheet items, and financial deterioration resulting from leveraged buy-outs or
takeovers. However, as discussed below, certain of the IDRs in the Portfolio may
be additionally insured or secured by letters of credit issued by banks or
otherwise guaranteed or secured to cover amounts due on the IDRs in the event of
default in payment by an issuer.
 
STATE AND LOCAL MUNICIPAL UTILITY OBLIGATIONS
 
     The ability of utilities to meet their obligations under revenue bonds
issued on their behalf is dependent on various factors, including the rates they
may charge their customers, the demand for their services and the cost of
providing those services. Utilities, in particular investor-owned utilities, are
subject to extensive regulation 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 and disallowances in granting rate
increases. Any difficulty in obtaining timely and adequate rate increases could
adversely affect a utility's results of operations.
 
     The demand for a utility's services is influenced by, among other factors,
competition, weather conditions and economic conditions. Electric utilities, for
example, have experienced increased competition as a result of the availability
of other energy sources, the effects of conservation on the use of electricity,
self-generation by industrial customers and the generation of electricity by
co-generators and other independent power producers. Also, increased competition
will result if federal regulators determine that utilities must open their
transmission lines to competitors. Utilities which distribute natural gas also
are subject to competition from alternative fuels, including fuel oil, propane
and coal and the impact of deregulation.
 
     The utility industry is an increasing cost business making the cost of
generating electricity more expensive and heightening its sensitivity to
regulation. A utility's costs are affected by its cost of capital, the
availability and cost of fuel and other factors. There can be no assurance that
a utility will be able to pass on these increased costs to customers through
increased rates. Utilities incur substantial capital expenditures for plant and
equipment. In the future they will also incur increasing capital and operating
expenses to comply with environmental legislation such as the Clean Air Act of
1990, and other energy, licensing and other laws and regulations relating to,
among other things, air emissions, the quality of drinking water, waste water
discharge, solid and hazardous substance handling and disposal, and siting and
licensing of facilities. Environmental legislation and regulations are changing
rapidly and are the subject of current public policy debate and legislative
proposals. It is increasingly likely that many utilities will be subject to more
stringent environmental standards in the future that could result in significant
capital expenditures. Future legislation and regulation could include, among
other things, regulation of so-called electromagnetic fields associated with
electric transmission and distribution lines as well as emissions of carbon
dioxide and other so-called greenhouse gases associated with the burning of
fossil fuels. Compliance
 
                                       4
<PAGE>
with these requirements may limit a utility's operations or require substantial
investments in new equipment and, as a result, may adversely affect a utility's
results of operations.
 
     The electric utility industry in general is subject to various external and
additional factors including (a) the effects of inflation upon the costs of
operation and construction, (b) uncertainties in predicting future load
requirements, (c) increased financing requirements coupled with limited
availability of capital, (d) exposure to cancellation and penalty charges on new
generating units under construction, (e) problems of cost and availability of
fuel, (f) litigation and proposed legislation designed to delay or prevent
construction of generating and other facilities, (g) the uncertain effects of
conservation on the use of electric energy and (h) increased competition as a
result of the availability of other energy sources and state deregulation
efforts. These factors may delay the construction and increase the cost of new
facilities, limit the use of, or necessitate costly modifications to, existing
facilities, impair the access of electric utilities to credit markets, or
substantially increase the cost of credit for electric generating facilities.
 
     The National Energy Policy Act ('NEPA'), which became law in October, 1992,
makes it mandatory for a utility to permit non-utility generators of electricity
access to its transmission system for wholesale customers, thereby increasing
competition for electric utilities. NEPA also mandated demand-side management
policies to be considered by utilities. NEPA prohibits the Federal Energy
Regulatory Commission from mandating electric utilities to engage in retail
wheeling, which is competition among suppliers of electric generation to provide
electricity to retail customers (particularly industrial retail customers) of a
utility. However, under NEPA, a state can mandate retail wheeling under certain
conditions. California, Michigan, New Mexico and Ohio have instituted
investigations into the possible introduction of retail wheeling within their
respective states, which could foster competition among the utilities. Retail
wheeling might result in the issue of stranded investment (investment in assets
not being recovered in base rates), thus hampering a utility's ability to meet
its obligations.
 
     There is concern by the public, the scientific community, and the U.S.
Congress regarding environmental damage resulting from the use of fossil fuels.
Congressional support for the increased regulation of air, water, and soil
contaminants is building and there are a number of pending or recently enacted
legislative proposals which may affect the electric utility industry. In
particular, on November 15, 1990, legislation was signed into law that
substantially revises the Clean Air Act (the '1990 Amendments'). The 1990
Amendments seek to improve the ambient air quality throughout the United States
by the year 2000. A main feature of the 1990 Amendments is the reduction of
sulphur dioxide and nitrogen oxide emissions caused by electric utility power
plants, particularly those fueled by coal. Under the 1990 Amendments the U.S.
Environmental Protection Agency ('EPA') must develop limits for nitrogen oxide
emissions by 1993. The sulphur dioxide reduction will be achieved in two phases.
Phase I addresses specific generating units named in the 1990 Amendments. In
Phase II the total U.S. emissions will be capped at 8.9 million tons by the year
2000. The 1990 Amendments contain provisions for allocating allowances to power
plants based on historical or calculated levels. An allowance is defined as the
authorization to emit one ton of sulphur dioxide.
 
     The 1990 Amendments also provide for possible further regulation of toxic
air emissions from electric generating units pending the results of several
federal government studies to be presented to Congress by the end of 1995 with
respect to anticipated hazards to public health, available corrective
technologies, and mercury toxicity.
 
     Electric utilities which own or operate nuclear power plants are exposed to
risks inherent in the nuclear industry. These risks include exposure to new
requirements resulting from extensive federal and state regulatory oversight,
public controversy, decommissioning costs, and spent fuel and radioactive waste
disposal issues. While nuclear power construction risks are no longer of
paramount concern, the emerging issue is radioactive waste disposal. In
addition, nuclear plants typically require substantial capital additions and
modifications throughout their operating lives to meet safety, environmental,
operational and regulatory requirements and to replace and upgrade various plant
systems. The high degree of regulatory monitoring and controls imposed on
nuclear plants could cause a plant to be out of service or on limited service
for long periods. When a nuclear facility owned by an investor-owned utility or
a state or local municipality is out of service or operating on a limited
service basis, the utility operator or its owners may be liable for the recovery
of replacement power costs. Risks of substantial liability also arise from the
operation of nuclear facilities and from the use, handling, and possible
radioactive emissions associated with nuclear fuel. Insurance may not cover all
types or amounts of loss which may be experienced in connection with the
ownership and operation of a nuclear plant and severe financial consequences
could result from a significant accident or occurrence. The Nuclear Regulatory
Commission has promulgated regulations mandating the establishment of funded
reserves to assure financial capability for the eventual
 
                                       5
<PAGE>
decommissioning of licensed nuclear facilities. These funds are to be accrued
from revenues in amounts currently estimated to be sufficient to pay for
decommissioning costs. Since there have been very few nuclear plants
decommissioned to date, these estimates may be unrealistic.
 
     The ability of state and local joint action power agencies to make payments
on bonds they have issued is dependent in large part on payments made to them
pursuant to power supply or similar agreements. Courts in Washington, Oregon and
Idaho have held that certain agreements between the Washington Public Power
Supply System ('WPPSS') and the WPPSS participants are unenforceable because the
participants did not have the authority to enter into the agreements. While
these decisions are not specifically applicable to agreements entered into by
public entities in other states, they may cause a reexamination of the legal
structure and economic viability of certain projects financed by joint action
power agencies, which might exacerbate some of the problems referred to above
and possibly lead to legal proceedings questioning the enforceability of
agreements upon which payment of these bonds may depend.
 
LEASE RENTAL OBLIGATIONS
 
     Lease rental obligations are issued for the most part by governmental
authorities that have no taxing power or other means of directly raising
revenues. Rather, the authorities are financing vehicles created solely for the
construction of buildings (administrative offices, convention centers and
prisons, for example) or the purchase of equipment (police cars and computer
systems, for example) that will be used by a state or local government (the
'lessee'). Thus, the obligations are subject to the ability and willingness of
the lessee government to meet its lease rental payments which include debt
service on the obligations. Willingness to pay may be subject to changes in the
views of citizens and government officials as to the essential nature of the
finance project. Lease rental obligations are subject, in almost all cases, to
the annual appropriation risk, i.e., the lessee government is not legally
obligated to budget and appropriate for the rental payments beyond the current
fiscal year. These obligations are also subject to the risk of abatement in many
states--rental obligations cease in the event that damage, destruction or
condemnation of the project prevents its use by the lessee. (In these cases,
insurance provisions and reserve funds designed to alleviate this risk become
important credit factors). In the event of default by the lessee government,
there may be significant legal and/or practical difficulties involved in the
reletting or sale of the project. Some of these issues, particularly those for
equipment purchase, contain the so-called 'substitution safeguard', which bars
the lessee government, in the event it defaults on its rental payments, from the
purchase or use of similar equipment for a certain period of time. This
safeguard is designed to insure that the lessee government will appropriate the
necessary funds even though it is not legally obligated to do so, but its
legality remains untested in most, if not all, states.
 
SINGLE FAMILY AND MULTI-FAMILY HOUSING OBLIGATIONS
 
     Multi-family housing revenue bonds and single family mortgage revenue bonds
are state and local housing issues that have been issued to provide financing
for various housing projects. Multi-family housing revenue bonds are payable
primarily from the revenues derived from mortgage loans to housing projects for
low to moderate income families. Single-family mortgage revenue bonds are issued
for the purpose of acquiring from originating financial institutions notes
secured by mortgages on residences.
 
     Housing obligations are not general obligations of the issuer although
certain obligations may be supported to some degree by Federal, state or local
housing subsidy programs. Budgetary constraints experienced by these programs as
well as the failure by a state or local housing issuer to satisfy the
qualifications required for coverage under these programs or any legal or
administrative determinations that the coverage of these programs is not
available to a housing issuer, probably will result in a decrease or elimination
of subsidies available for payment of amounts due on the issuer's obligations.
The ability of housing issuers to make debt service payments on their
obligations will also be affected by various economic and non-economic
developments including, among other things, the achievement and maintenance of
sufficient occupancy levels and adequate rental income in multi-family projects,
the rate of default on mortgage loans underlying single family issues and the
ability of mortgage insurers to pay claims, employment and income conditions
prevailing in local markets, increases in construction costs, taxes, utility
costs and other operating expenses, the managerial ability of project managers,
changes in laws and governmental regulations and economic trends generally in
the localities in which the projects are situated. Occupancy of multi-family
housing projects may also be adversely affected by high rent levels and income
limitations imposed under Federal, state or local programs.
 
     All single family mortgage revenue bonds and certain multi-family housing
revenue bonds are prepayable over the life of the underlying mortgage or
mortgage pool, and therefore the average life of housing obligations
 
                                       6
<PAGE>
cannot be determined. However, the average life of these obligations will
ordinarily be less than their stated maturities. Single-family issues are
subject to mandatory redemption in whole or in part from prepayments on
underlying mortgage loans; mortgage loans are frequently partially or completely
prepaid prior to their final stated maturities as a result of events such as
declining interest rates, sale of the mortgaged premises, default, condemnation
or casualty loss. Multi-family issues are characterized by mandatory redemption
at par upon the occurrence of monetary defaults or breaches of covenants by the
project operator. Additionally, housing obligations are generally subject to
mandatory partial redemption at par to the extent that proceeds from the sale of
the obligations are not allocated within a stated period (which may be within a
year of the date of issue). To the extent that these obligations were valued at
a premium when a Holder purchased Units, any prepayment at par would result in a
loss of capital to the Holder and, in any event, reduce the amount of income
that would otherwise have been paid to Holders.
 
     The tax exemption for certain housing revenue bonds depends on
qualification under Section 143 of the Internal Revenue Code of 1986, as amended
(the 'Code'), in the case of single family mortgage revenue bonds or Section
142(a)(7) of the Code or other provisions of Federal law in the case of certain
multi-family housing revenue bonds (including Section 8 assisted bonds). These
sections of the Code or other provisions of Federal law contain certain ongoing
requirements, including requirements relating to the cost and location of the
residences financed with the proceeds of the single family mortgage revenue
bonds and the income levels of tenants of the rental projects financed with the
proceeds of the multi-family housing revenue bonds. While the issuers of the
bonds and other parties, including the originators and servicers of the
single-family mortgages and the owners of the rental projects financed with the
multi-family housing revenue bonds, generally covenant to meet these ongoing
requirements and generally agree to institute procedures designed to ensure that
these requirements are met, there can be no assurance that these ongoing
requirements will be consistently met. The failure to meet these requirements
could cause the interest on the bonds to become taxable, possibly retroactively
from the date of issuance, thereby reducing the value of the bonds, subjecting
the Holders to unanticipated tax liabilities and possibly requiring the Trustee
to sell the bonds at reduced values. Furthermore, any failure to meet these
ongoing requirements might not constitute an event of default under the
applicable mortgage or permit the holder to accelerate payment of the bond or
require the issuer to redeem the bond. In any event, where the mortgage is
insured by the Federal Housing Administration, its consent may be required
before insurance proceeds would become payable to redeem the mortgage bonds.
 
HOSPITAL AND HEALTH CARE FACILITY OBLIGATIONS
 
     The ability of hospitals and other health care facilities to meet their
obligations with respect to revenue bonds issued on their behalf is dependent on
various factors, including the level of payments received from private
third-party payors and government programs and the cost of providing health care
services.
 
     A significant portion of the revenues of hospitals and other health care
facilities is derived from private third-party payors and government programs,
including the Medicare and Medicaid programs. Both private third-party payors
and government programs have undertaken cost containment measures designed to
limit payments made to health care facilities. Furthermore, government programs
are subject to statutory and regulatory changes, retroactive rate adjustments,
administrative rulings and government funding restrictions, all of which may
materially decrease the rate of program payments for health care facilities.
Certain special revenue obligations (i.e., Medicare or Medicaid revenues) may be
payable subject to appropriations by state legislatures. There can be no
assurance that payments under governmental programs will remain at levels
comparable to present levels or will, in the future, be sufficient to cover the
costs allocable to patients participating in such programs. In addition, there
can be no assurance that a particular hospital or other health care facility
will continue to meet the requirements for participation in such programs.
 
     The costs of providing health care services are subject to increase as a
result of, among other factors, changes in medical technology and increased
labor costs. In addition, health care facility construction and operation is
subject to federal, state and local regulation relating to the adequacy of
medical care, equipment, personnel, operating policies and procedures,
rate-setting, and compliance with building codes and environmental laws.
Facilities are subject to periodic inspection by governmental and other
authorities to assure continued compliance with the various standards necessary
for licensing and accreditation. These regulatory requirements are subject to
change and, to comply, it may be necessary for a hospital or other health care
facility to incur substantial capital expenditures or increased operating
expenses to effect changes in its facilities, equipment, personnel and services.
 
     Hospitals and other health care facilities are subject to claims and legal
actions by patients and others in the ordinary course of business. Although
these claims are generally covered by insurance, there can be no assurance
 
                                       7
<PAGE>
that a claim will not exceed the insurance coverage of a health care facility or
that insurance coverage will be available to a facility. In addition, a
substantial increase in the cost of insurance could adversely affect the results
of operations of a hospital or other health care facility. The Clinton
Administration may impose regulations which could limit price increases for
hospitals or the level of reimbursements for third-party payors or other
measures to reduce health care costs and make health care available to more
individuals, which would reduce profits for hospitals. Some states, such as New
Jersey, have significantly changed their reimbursement systems. If a hospital
cannot adjust to the new system by reducing expenses or raising rates, financial
difficulties may arise. Also, Blue Cross has denied reimbursement for some
hospitals for services other than emergency room services. The lost volume would
reduce revenues unless replacement patients were found.
 
     Certain hospital bonds may provide for redemption at par at any time upon
the sale by the issuer of the hospital facilities to a non-affiliated entity, if
the hospital becomes subject to ad valorem taxation, or in various other
circumstances. For example, certain hospitals may have the right to call bonds
at par if the hospital may be legally required because of the bonds to perform
procedures against specified religious principles or to disclose information
that is considered confidential or privileged. Certain FHA-insured bonds may
provide that all or a portion of those bonds, otherwise callable at a premium,
can be called at par in certain circumstances. If a hospital defaults upon a
bond obligation, the realization of Medicare and Medicaid receivables may be
uncertain and, if the bond obligation is secured by the hospital facilities,
legal restrictions on the ability to foreclose upon the facilities and the
limited alternative uses to which a hospital can be put may severely reduce its
collateral value.
 
     The Internal Revenue Service is currently engaged in a program of intensive
audits of certain large tax-exempt hospital and health care facility
organizations. Although these audits have not yet been completed, it has been
reported that the tax-exempt status of some of these organizations may be
revoked. At this time, it is uncertain whether any of the hospital and health
care facility obligations held by the Fund will be affected by such audit
proceedings.
 
AIRPORT, PORT AND HIGHWAY REVENUE OBLIGATIONS
 
     Certain facility revenue bonds are payable from and secured by the revenues
from the ownership and operation of particular facilities, such as airports
(including airport terminals and maintenance facilities), bridges, marine
terminals, turnpikes and port authorities. For example, the major portion of
gross airport operating income is generally derived from fees received from
signatory airlines pursuant to use agreements which consist of annual payments
for airport use, occupancy of certain terminal space, facilities, service fees,
concessions and leases. Airport operating income may therefore be affected by
the ability of the airlines to meet their obligations under the use agreements.
The air transport industry is experiencing significant variations in earnings
and traffic, due to increased competition, excess capacity, increased aviation
fuel, deregulation, traffic constraints and other factors. As a result, several
airlines are experiencing severe financial difficulties. Several airlines
including America West Airlines have sought protection from their creditors
under Chapter 11 of the Bankruptcy Code. In addition, other airlines such as
Midway Airlines, Inc., Eastern Airlines, Inc. and Pan American Corporation have
been liquidated. However, Continental Airlines and Trans World Airlines have
emerged from bankruptcy. The Sponsors cannot predict what effect these industry
conditions may have on airport revenues which are dependent for payment on the
financial condition of the airlines and their usage of the particular airport
facility. Furthermore, proposed legislation would provide the U.S. Secretary of
Transportation with the temporary authority to freeze airport fees upon the
occurrence of disputes between a particular airport facility and the airlines
utilizing that facility.
 
     Similarly, payment on bonds related to other facilities is dependent on
revenues from the projects, such as use fees from ports, tolls on turnpikes and
bridges and rents from buildings. Therefore, payment may be adversely affected
by reduction in revenues due to such factors and increased cost of maintenance
or decreased use of a facility, lower cost of alternative modes of
transportation or scarcity of fuel and reduction or loss of rents.
 
SOLID WASTE DISPOSAL BONDS
 
     Bonds issued for solid waste disposal facilities are generally payable from
dumping fees and from revenues that may be earned by the facility on the sale of
electrical energy generated in the combustion of waste products. The ability of
solid waste disposal facilities to meet their obligations depends upon the
continued use of the facility, the successful and efficient operation of the
facility and, in the case of waste-to-energy facilities, the continued ability
of the facility to generate electricity on a commercial basis. All of these
factors may be affected by a failure of municipalities to fully utilize the
facilities, an insufficient supply of waste for disposal due to
 
                                       8
<PAGE>
economic or population decline, rising construction and maintenance costs, any
delays in construction of facilities, lower-cost alternative modes of waste
processing and changes in environmental regulations. Because of the relatively
short history of this type of financing, there may be technological risks
involved in the satisfactory construction or operation of the projects exceeding
those associated with most municipal enterprise projects. Increasing
environmental regulation on the federal, state and local level has a significant
impact on waste disposal facilities. While regulation requires more waste
producers to use waste disposal facilities, it also imposes significant costs on
the facilities. These costs include compliance with frequently changing and
complex regulatory requirements, the cost of obtaining construction and
operating permits, the cost of conforming to prescribed and changing equipment
standards and required methods of operation and, for incinerators or
waste-to-energy facilities, the cost of disposing of the waste residue that
remains after the disposal process in an environmentally safe manner. In
addition, waste disposal facilities frequently face substantial opposition by
environmental groups and officials to their location and operation, to the
possible adverse effects upon the public health and the environment that may be
caused by wastes disposed of at the facilities and to alleged improper operating
procedures. Waste disposal facilities benefit from laws which require waste to
be disposed of in a certain manner but any relaxation of these laws could cause
a decline in demand for the facilities' services. Finally, waste-to-energy
facilities are concerned with many of the same issues facing utilities insofar
as they derive revenues from the sale of energy to local power utilities (see
State and Local Municipal Utility Obligations above).
 
SPECIAL TAX BONDS
 
     Special tax bonds are payable from and secured by the revenues derived by a
municipality from a particular tax such as a tax on the rental of a hotel room,
on the purchase of food and beverages, on the rental of automobiles or on the
consumption of liquor. Special tax bonds are not secured by the general tax
revenues of the municipality, and they do not represent general obligations of
the municipality. Therefore, payment on special tax bonds may be adversely
affected by a reduction in revenues realized from the underlying special tax due
to a general decline in the local economy or population or due to a decline in
the consumption, use or cost of the goods and services that are subject to
taxation. Also, should spending on the particular goods or services that are
subject to the special tax decline, the municipality may be under no obligation
to increase the rate of the special tax to ensure that sufficient revenues are
raised from the shrinking taxable base.
 
TRANSIT AUTHORITY OBLIGATIONS
 
     Mass transit is generally not self-supporting from fare revenues.
Therefore, additional financial resources must be made available to ensure
operation of mass transit systems as well as the timely payment of debt service.
Often such financial resources include Federal and state subsidies, lease
rentals paid by funds of the state or local government or a pledge of a special
tax such as a sales tax or a property tax. If fare revenues or the additional
financial resources do not increase appropriately to pay for rising operating
expenses, the ability of the issuer to adequately service the debt may be
adversely affected.
 
MUNICIPAL WATER AND SEWER REVENUE BONDS
 
     Water and sewer bonds are generally payable from user fees. The ability of
state and local water and sewer authorities to meet their obligations may be
affected by failure of municipalities to utilize fully the facilities
constructed by these authorities, economic or population decline and resulting
decline in revenue from user charges, rising construction and maintenance costs
and delays in construction of facilities, impact of environmental requirements,
failure or inability to raise user charges in response to increased costs, the
difficulty of obtaining or discovering new supplies of fresh water, the effect
of conservation programs and the impact of 'no growth' zoning ordinances. In
some cases this ability may be affected by the continued availability of Federal
and state financial assistance and of municipal bond insurance for future bond
issues.
 
UNIVERSITY AND COLLEGE OBLIGATIONS
 
     The ability of universities and colleges to meet their obligations is
dependent upon various factors, including the size and diversity of their
sources of revenues, enrollment, reputation, management expertise, the
availability and restrictions on the use of endowments and other funds, the
quality and maintenance costs of campus facilities, and, in the case of public
institutions, the financial condition of the relevant state or other
governmental entity and its policies with respect to education. The
institution's ability to maintain enrollment levels will depend on such factors
as tuition costs, demographic trends, geographic location, geographic diversity
and quality of the student body, quality of the faculty and the diversity of
program offerings.
 
                                       9
<PAGE>
     Legislative or regulatory action in the future at the Federal, state or
local level may directly or indirectly affect eligibility standards or reduce or
eliminate the availability of funds for certain types of student loans or grant
programs, including student aid, research grants and work-study programs, and
may affect indirect assistance for education.
 
PUERTO RICO
 
     The Portfolio may contain Debt Obligations of issuers which will be
affected by general economic conditions in Puerto Rico. Puerto Rico's
unemployment rate remains significantly higher than the U.S. unemployment rate.
Furthermore, the economy is largely dependent for its development upon U.S.
policies and programs that are being reviewed and may be eliminated.
 
     The Puerto Rican economy is affected by a number of Commonwealth and
Federal investment incentive programs. For example, Section 936 of the Code
provides for a credit against Federal income taxes for U.S. companies operating
on the island if certain requirements are met. The Omnibus Budget Reconciliation
Act of 1993 imposes limits on such credit, effective for tax years beginning
after 1993. In addition, from time to time proposals are introduced in Congress
which, if enacted into law, would eliminate some or all of the benefits of
Section 936. Although no assessment can be made at this time of the precise
effect of such limitation, it is expected that the limitation of Section 936
credits would have a negative impact on Puerto Rico's economy.
 
     Aid for Puerto Rico's economy has traditionally depended heavily on Federal
programs, and current Federal budgetary policies suggest that an expansion of
aid to Puerto Rico is unlikely. An adverse effect on the Puerto Rican economy
could result from other U.S. policies, including a reduction of tax benefits for
distilled products, further reduction in transfer payment programs such as food
stamps, curtailment of military spending and policies which could lead to a
stronger dollar.
 
     In a plebiscite held in November, 1993, the Puerto Rican electorate chose
to continue Puerto Rico's Commonwealth status. Previously proposed legislation,
which was not enacted, would have preserved the federal tax exempt status of the
outstanding debts of Puerto Rico and its public corporations regardless of the
outcome of the referendum, to the extent that similar obligations issued by
states are so treated and subject to the provisions of the Code currently in
effect. There can be no assurance that any pending or future legislation finally
enacted will include the same or similar protection against loss of tax
exemption. The November 1993 plebiscite can be expected to have both direct and
indirect consequences on such matters as the basic characteristics of future
Puerto Rico debt obligations, the markets for these obligations, and the types,
levels and quality of revenue sources pledged for the payment of existing and
future debt obligations. Such possible consequences include legislative
proposals seeking restoration of the status of Section 936 benefits otherwise
subject to the limitations discussed above. However, no assessment can be made
at this time of the economic and other effects of a change in federal laws
affecting Puerto Rico as a result of the November 1993 plebiscite.
 
OBLIGATIONS BACKED BY LETTERS OF CREDIT
 
     Certain Debt Obligations may be secured by letters of credit issued by
commercial banks or savings banks, savings and loan associations and similar
institutions ('thrifts') or are direct obligations of banks or thrifts pursuant
to 'loans-to-lenders' programs. The letter of credit may be drawn upon, and the
Debt Obligations consequently redeemed, if an issuer fails to pay amounts due on
the Debt Obligation or defaults under its reimbursement agreement with the
issuer of the letter of credit or, in certain cases, if the interest on the Debt
Obligation is deemed to be taxable and full payment of amounts due is not made
by the issuer. The letters of credit are irrevocable obligations of the issuing
institutions, which are subject to extensive governmental regulations which may
limit both the amounts and types of loans and other financial commitments which
may be made and interest rates and fees which may be charged.
 
     The profitability of financial institutions (and therefore their ability to
honor letters of credit or guarantees) is largely dependent upon the
availability and cost of funds for the purpose of financing lending operations
under prevailing money market conditions. Also, general economic conditions play
an important part in the operations of this industry and exposure to credit
losses arising from possible financial difficulties of borrowers might affect an
institution's ability to meet its obligations. In the late 1980's and early
1990's the credit ratings of U.S. banks and bank holding companies were subject
to extensive downgrades due primarily to deterioration in asset quality and the
attendant impact on earnings and capital adequacy. Major U.S. banks, in
particular, suffered from a decline in asset quality in the areas of
construction and commercial real estate loans. These problem loans have been
largely addressed. During the early 1990's the credit ratings of many foreign
banks have also been subject to
 
                                       10
<PAGE>
significant downgrades due to a deterioration in asset quality which has
negatively impacted earnings and capital adequacy. The decline in asset quality
of major foreign banks has been brought about largely by recessionary conditions
in their local economies. The Federal Deposit Insurance Corporation ('FDIC')
indicated that in 1990, 168 federally insured banks with an aggregate total of
$45.7 billion in assets failed and that in 1991, 124 federally insured banks
with an aggregate total of $64.3 billion in assets failed. During 1992, the FDIC
resolved 120 failed banks with combined assets of $44.2 billion. In 1993, a
total of 41 banks with combined assets of $3.5 billion were closed. The 1993
total was the lowest level in twelve years. Bank holding companies and other
financial institutions may not be as highly regulated as banks, and may be more
able to expand into other non-financial and non-traditional businesses.
 
     Historically, thrifts primarily financed residential and commercial real
estate by making fixed-rate mortgage loans and funded those loans from various
types of deposits. Thrifts were restricted as to the types of accounts which
could be offered and the rates that could be paid on those accounts. During
periods of high interest rates, large amounts of deposits were withdrawn as
depositors invested in Treasury bills and notes and in money market funds which
provided liquidity and high yields not subject to regulation. As a result the
cost of thrifts' funds exceeded income from mortgage loan portfolios and other
investments, and their financial positions were adversely affected. Laws and
regulations eliminating interest rate ceilings and restrictions on types of
accounts that may be offered by thrifts were designed to permit thrifts to
compete for deposits on the basis of current market rates and to improve their
financial positions.
 
     Recent legislation, including the Financial Institutions Reform, Recovery
and Enforcement Act of 1989, the Federal Deposit Insurance Corporation
Improvement Act of 1991 ('FDICIA') and the Resolution Trust Corporation
Refinancing, Restructuring, and Improvement Act of 1991 have significantly
altered the legal rules and regulations governing banks and thrifts and mandated
early and aggressive regulatory intervention for unhealthy institutions. For
those thrifts that have failed, either the FDIC or the Resolution Trust
Corporation ('RTC') will be appointed as receiver or conservator. Periodic
efforts by recent Administrations to introduce legislation broadening the
ability of banks and thrifts to compete with new products generally have not
been successful, but if enacted could lead to more failures as a result of
increased competition and added risks. Failure to enact such legislation, on the
other hand, may lead to declining earnings and an inability to compete with
unregulated financial institutions. Efforts to expand the ability of federal
thrifts to branch on an interstate basis have been initially successful through
promulgation of regulations. Legislation to liberalize interstate branching for
banks has been stalled in Congress, but may be more successful this year.
Consolidation is likely to continue in both cases. The Securities and Exchange
Commission ('SEC') is attempting to require the expanded use of market value
accounting by banks and thrifts, and has imposed rules requiring market
accounting for investment securities held for sale. Adoption of these and
similar rules may result in increased volatility in the reported health of the
industry and mandated regulatory intervention to correct such problems.
 
     Investors should realize that should the FDIC or the RTC make payment under
a letter of credit prior to the scheduled maturity or disposition dates of the
related Debt Obligation their investment will be returned sooner than originally
anticipated. The possibility of such early payment has been increased
significantly by the enactment of FDICIA, which requires federal regulators of
insured banks, savings banks, and thrifts to act more quickly to address the
problems of undercapitalized institutions than previously, and specifies in more
detail the actions they must take. One such requirement virtually compels the
appointment of a receiver or conservator for any institution when its ratio of
tangible equity to total assets declines to two percent. Others force aggressive
intervention in the business of an institution at even earlier stages of
deterioration.
 
     Certain letters of credit or guarantees backing Debt Obligations may have
been issued by a foreign bank or corporation or similar entity (a 'Foreign
Guarantee'). On the basis of information available to the Sponsors at the
present time no Foreign Guarantee is subject to exchange control restrictions
under existing law which would materially interfere with payments to the Fund
under the Foreign Guarantee. However, there can be no assurance that exchange
control regulations might not be adopted in the future which might affect
adversely the payment to the Fund. Nor are there any withholding taxes under
existing law applicable to payments made on any Foreign Guarantee. While there
can be no assurance that withholding taxes might not be imposed in the future,
provision is made in the instruments governing any Foreign Guarantee that, in
substance, to the extent permitted by applicable law, additional payments will
be made by the guarantor so that the total amount paid, after deduction of any
applicable tax, will not be less than the amount then due and payable on the
Foreign Guarantee. The adoption of exchange control regulations and other legal
restrictions could have an adverse impact on the marketability of any Debt
Obligations backed by a Foreign Guarantee and on the ability of the Fund to
satisfy its obligation to redeem Units tendered to the Trustee for redemption
(see How to Sell).

OBLIGATIONS BACKED BY INSURANCE
 
     Certain Debt Obligations (the 'Insured Debt Obligations') may be insured or
guaranteed by AMBAC Indemnity Corporation ('AMBAC'), Asset Guaranty Reinsurance
Co. ('Asset Guaranty'), Capital Guaranty Insurance Company ('CGIC'), Capital
Markets Assurance Corp. ('CAPMAC'), Connie Lee Insurance Company ('Connie Lee'),
Continental Casualty Company ('Continental'), Financial Guaranty Insurance
Company ('Financial Guaranty'), Financial Security Assurance Inc. ('FSA'),
Firemen's Insurance Company of Newark, New Jersey ('Firemen's'), Municipal Bond
Investors Assurance Corporation ('MBIA') or National Union Fire Insurance
Company of Pittsburgh, Pa. ('National Union') (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 agency. The ratings are subject to change at any time at the
discretion of the rating agencies. In determining whether to insure bonds, the
Insurance Companies severally apply their own standards. The cost of this
insurance is borne either by the issuers or previous owners of the bonds or by
the Sponsors. The insurance policies are non-cancellable and will continue in
force so long as the Insured Debt Obligations are outstanding and the insurers
remain in business. The insurance policies guarantee the timely payment of
principal and interest on but do not guarantee the market value of the Insured
Debt Obligations or the value of the Units. The insurance policies generally do
not provide for accelerated payments of principal or cover redemptions resulting
from events of taxability. If the issuer of any Insured Debt Obligation should
fail to make an interest or principal payment, the insurance policies generally
provide that the Trustee or its agent shall give notice of nonpayment to the
Insurance Company or its agent and provide evidence of the Trustee's right to
receive payment. The Insurance Company is then required to disburse the amount
of the failed payment to the Trustee or its agent and is thereafter subrogated
to the Trustee's right to receive payment from the issuer.
 
      Financial information relating to the Insurance Companies has been
obtained from publicly available information. No representation is made as to
the accuracy or adequacy of the information or as to the absence of material
adverse changes since the information was made available to the public. Standard
& Poor's has rated the Units of any Insured Fund AAA because the Insurance
Companies have insured the Debt Obligations. The assignment of such AAA ratings
is due to Standard & Poor's assessment of the creditworthiness of the Insurance
Companies and of their ability to pay claims on their policies of insurance. In
the event that Standard & Poor's reassesses the creditworthiness of any
Insurance Company which would result in the rating of an Insured Fund being
reduced, the Sponsors are authorized to direct the Trustee to obtain other
insurance.
 
      The following are brief descriptions of certain Insurance Companies. The
financial information presented for each company has been determined on a
statutory basis and is unaudited.
 
      AMBAC is a Wisconsin-domiciled stock insurance company, regulated by the
Insurance Department of the State of Wisconsin, and licensed to do business in
various states, with admitted assets of approximately $1,988,000,000 and
policyholders' surplus of approximately $749,000,000 as of March 31, 1994. AMBAC
is a wholly-owned subsidiary of AMBAC Inc., a financial holding company which is
publicly owned following a complete divestiture by Citibank during the first
quarter of 1992.
 
      Asset Guaranty is a New York State insurance company licensed to write
financial guarantee, credit, residual value and surety insurance. Asset Guaranty
commenced operations in mid-1988 by providing reinsurance to several major
monoline insurers. The parent holding company of Asset Guaranty, Asset Guarantee
Inc. (AGI), merged with Enhance Financial Services (EFS) in June, 1990 to form
Enhance Financial Services Group Inc. (EFSG). The two main, 100%-owned
subsidiaries of EFSG, Asset Guaranty and Enhance Reinsurance Company, share
common management and physical resources. After an initial public offering
completed in February 1992 and the sale by Merrill Lynch & Co. of its stake,
EFSG is 49.8%-owned by the public, 29.9% by US West Financial Services, 14.1% by
Manufacturers Life Insurance Co. and 6.2% by senior management. Both ERC and
Asset Guaranty are rated 'AAA' for claims paying ability by Duff & Phelps, ERC
is rated triple-A for claims-paying-ability for both S&P and Moody's. Asset
Guaranty received a 'AA' claims-paying-ability rating from S&P during August
1993, but remains unrated by Moody's. As of March 31, 1994 Asset Guaranty had
admitted assets of approximately $142,000,000 and policyholders' surplus of
approximately $73,000,000.
 
      CGIC, a monoline bond insurer headquartered in San Francisco, California,
was established in November 1986 to assume the financial guaranty business of
United States Fidelity and Guaranty Company ('USF&G'). It is a wholly-owned
subsidiary of Capital Guaranty Corporation ('CGC') whose stock is owned by:
Constellation Investments, Inc., an affiliate of Baltimore Gas & Electric,
Fleet/Norstar Financial Group, Inc., Safeco Corporation, Sibag Finance
Corporation, an affiliate of Siemens AG, USF&G, the eighth largest
property/casualty

company in the U.S. as measured by net premiums written, and CGC management. As
of March 31, 1994, CGIC had total admitted assets of approximately $288,000,000
and policyholders' surplus of approximately $171,000,000.
 
      CAPMAC commenced operations in December 1987, as the second mono-line
financial guaranty insurance company (after FSA) organized solely to insure
non-municipal obligations. CAPMAC, a New York corporation, is a wholly-owned
subsidiary of CAPMAC Holdings, Inc. (CHI), which was sold in 1992 by Citibank
(New York State) to a group of 12 investors led by the following: Dillon Read's
Saratoga Partners II; L.P., an acquisition fund; Caprock Management, Inc.,
representing Rockefeller family interests; Citigrowth Fund, a Citicorp venture
capital group; and CAPMAC senior management and staff. These groups control
approximately 70% of the stock of CHI. CAPMAC had traditionally specialized in
guaranteeing consumer loan and trade receivable asset-backed securities. Under
the new ownership group CAPMAC intends to become involved in the municipal bond
insurance business, as well as their traditional non-municipal business. As of
March 31, 1994 CAPMAC's admitted assets were approximately $188,000,000 and its
policyholders' surplus was approximately $145,000,000.
 
      Connie Lee is a wholly owned subsidiary of College Construction Loan
Insurance Association ('CCLIA'), a government-sponsored enterprise established
by Congress to provide American academic institutions with greater access to
low-cost capital through credit enhancement. Connie Lee, the operating insurance
company, was incorporated in 1987 and began business as a reinsurer of
tax-exempt bonds of colleges, universities, and teaching hospitals with a
concentration on the hospital sector. During the fourth quarter of 1991 Connie
Lee began underwriting primary bond insurance which will focus largely on the
college and university sector. CCLIA's founding shareholders are the U.S.
Department of Education, which owns 36% of CCLIA, and the Student Loan Marketing
Association ('Sallie Mae'), which owns 14%. The other principal owners are:
Pennsylvania Public School Employees' Retirement System, Metropolitan Life
Insurance Company, Kemper Financial Services, Johnson family funds and trusts,
Northwestern University, Rockefeller & Co., Inc. administered trusts and funds,
and Stanford University. Connie Lee is domiciled in the state of Wisconsin and
has licenses to do business in 47 states and the District of Columbia. As of
March 31, 1994, its total admitted assets were approximately $185,000,000 and
policyholders' surplus was approximately $104,000,000.
 
     Continental is a wholly-owned subsidiary of CNA Financial Corp. and was
incorporated under the laws of Illinois in 1948. As of March 31, 1994,
Continental had policyholders' surplus of approximately $3,410,000,000 and
admitted assets of approximately $19,140,000,000. Continental is the lead
property-casualty company of a fleet of carriers nationally known and marketed
as 'CNA Insurance Companies'. CNA is rated AA+ by Standard & Poor's.
 
     Financial Guaranty, a New York stock insurance company, is a wholly-owned
subsidiary of FGIC Corporation, which is wholly owned by General Electric
Capital Corporation. The investors in the FGIC Corporation are not obligated to
pay the debts of or the claims against Financial Guaranty. Financial Guaranty
commenced its business of providing insurance and financial guarantees for a
variety of investment instruments in January 1984 and is currently authorized to
provide insurance in 49 states and the District of Columbia. It files reports
with state regulatory agencies and is subject to audit and review by those
authorities. As of March 31, 1994, its total admitted assets were approximately
$1,995,000,000 and its policyholders' surplus was approximately $805,000,000.
 
     FSA is a monoline property and casualty insurance company incorporated in
New York in 1984. It is a wholly-owned subsidiary of Financial Security
Assurance Holdings Ltd., which was acquired in December 1989 by US West, Inc.,
the regional Bell Telephone Company serving the Rocky Mountain and Pacific
Northwestern states. U.S. West is currently seeking to sell FSA. FSA is licensed
to engage in the surety business in 42 states and the District of Columbia. FSA
is engaged exclusively in the business of writing financial guaranty insurance,
on both tax-exempt and non-municipal securities. As of March 31, 1994, FSA had
policyholders' surplus of approximately $368,000,000 and total admitted assets
of approximately $759,000,000.

claims paying ability of which is rated AA-by Standard & Poor's. It provides
unconditional and non-cancellable insurance on industrial development revenue
bonds. As of March 31, 1994, the total admitted assets of Firemen's were
approximately $2,206,000,000 and its policyholders' surplus was approximately
$422,000,000.
 
                                       13
<PAGE>
     MBIA is the principal operating subsidiary of MBIA Inc. The principal
shareholders of MBIA Inc. were originally Aetna Casualty and Surety Company, The
Fund American Companies, Inc., subsidiaries of CIGNA Corporation and Credit
Local de France, CAECL, S.A. These principal shareholders now own approximately
13% of the outstanding common stock of MBIA Inc. following a series of four
public equity offerings over a five-year period. As of March 31, 1994, MBIA had
admitted assets of approximately $3,152,000,000 and policyholders' surplus of
approximately $998,000,000.
 
     National Union is a stock insurance company incorporated in Pennsylvania
and a wholly-owned subsidiary of American International Group, Inc. National
Union was organized in 1901 and is currently licensed to provide insurance in 50
states and the District of Columbia. It files reports with state insurance
regulatory agencies and is subject to regulation, audit and review by those
authorities including the State of New York Insurance Department. As of March
31, 1994, the total admitted assets and policyholders' surplus of National Union
were approximately $8,517,000,000 and approximately $1,422,000,000,
respectively.
 
     Insurance companies are subject to regulation and supervision in the
jurisdictions in which they do business under statutes which delegate
regulatory, supervisory and administrative powers to state insurance
commissioners. This regulation, supervision and administration relate, among
other things, to: the standards of solvency which must be met and maintained;
the licensing of insurers and their agents; the nature of and limitations on
investments; deposits of securities for the benefit of policyholders; approval
of policy forms and premium rates; periodic examinations of the affairs of
insurance companies; annual and other reports required to be filed on the
financial condition of insurers or for other purposes; and requirements
regarding reserves for unearned premiums, losses and other matters. Regulatory
agencies require that premium rates not be excessive, inadequate or unfairly
discriminatory. Insurance regulation in many states also includes 'assigned
risk' plans, reinsurance facilities, and joint underwriting associations, under
which all insurers writing particular lines of insurance within the jurisdiction
must accept, for one or more of those lines, risks that are otherwise
uninsurable. A significant portion of the assets of insurance companies is
required by law to be held in reserve against potential claims on policies and
is not available to general creditors.
 
     Although the Federal government does not regulate the business of
insurance, Federal initiatives can significantly impact the insurance business.
Current and proposed Federal measures which may significantly affect the
insurance business include pension regulation (ERISA), controls on medical care
costs, minimum standards for no-fault automobile insurance, national health
insurance, personal privacy protection, tax law changes affecting life insurance
companies or the relative desirability of various personal investment vehicles
and repeal of the current antitrust exemption for the insurance business. (If
this exemption is eliminated, it will substantially affect the way premium rates
are set by all property-liability insurers.) In addition, the Federal government
operates in some cases as a co-insurer with the private sector insurance
companies.
 
     Insurance companies are also affected by a variety of state and Federal
regulatory measures and judicial decisions that define and extend the risks and
benefits for which insurance is sought and provided. These include judicial
redefinitions of risk exposure in areas such as products liability and state and
Federal extension and protection of employee benefits, including pension,
workers' compensation, and disability benefits. These developments may result in
short-term adverse effects on the profitability of various lines of insurance.
Longer-term adverse effects can often be minimized through prompt repricing of
coverages and revision of policy terms. In some instances these developments may
create new opportunities for business growth. All insurance companies write
policies and set premiums based on actuarial assumptions about mortality,
injury, the occurrence of accidents and other insured events. These assumptions,
while well supported by past experience, necessarily do not take account of
future events. The occurrence in the future of unforeseen circumstances could
affect the financial condition of one or more insurance companies. The insurance
business is highly competitive and with the deregulation of financial service
businesses, it should become more competitive. In addition, insurance companies
may expand into non-traditional lines of business which may involve different
types of risks.
 
LITIGATION AND LEGISLATION
 
     To the best knowledge of the Sponsors, there is no litigation pending as of
the Initial Date of Deposit in respect of any Debt Obligations which might
reasonably be expected to have a material adverse effect upon the Fund. At any
time after the Initial Date of Deposit, litigation may be initiated on a variety
of grounds, or legislation may be enacted, with respect to Debt Obligations in
the Fund. Litigation, for example, challenging the
 
                                       14
<PAGE>
issuance of pollution control revenue bonds under environmental protection
statutes may affect the validity of Debt Obligations 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 Debt Obligation to the effect that the Debt Obligation has been
validly issued and that the interest thereon is exempt from 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 Debt Obligations.
 
     Under the Federal Bankruptcy Act, a political subdivision or public agency
or instrumentality of any state, including municipalities, may proceed to
restructure or otherwise alter the terms of its obligations, including those of
the type comprising the Fund's Portfolio. The Sponsors are unable to predict
what effect, if any, this type of legislation might have on the Fund.
 
     From time to time Congress considers proposals to tax the interest on state
and local obligations, such as the Debt Obligations. The Supreme Court clarified
in South Carolina v. Baker (decided April 20, 1988) that the U.S. Constitution
does not prohibit Congress from passing a nondiscriminatory tax on interest on
state and local obligations. This type of legislation, if enacted into law,
could adversely affect an investment in Units. Holders are urged to consult
their own tax advisers.
 
PAYMENT OF THE DEBT OBLIGATIONS AND LIFE OF THE FUND
 
     Because certain of the Debt Obligations from time to time may be redeemed
or prepaid or will mature in accordance with their terms or may be sold under
certain circumstances described herein, no assurance can be given that the Fund
will retain for any length of time its present size and composition. Many of the
Debt Obligations may be subject to redemption prior to their stated maturity
dates pursuant to optional refunding or sinking fund redemption provisions or
otherwise (see Portfolio in Part A). In general, optional refunding redemption
provisions are more likely to be exercised when the offer side evaluation is at
a premium over par than when it is at a discount from par. Generally, the offer
side evaluation of Debt Obligations will be at a premium over par when market
interest rates fall below the coupon rate on the Debt Obligations. The
percentage of the face amount of Debt Obligations which were acquired on the
Date of Deposit at an offer side evaluation in excess of par is set forth under
Investment Summary. Certain Debt Obligations in the Portfolio may be subject to
sinking fund provisions early in the life of the Fund. These provisions are
designed to redeem a significant portion of an issue gradually over the life of
the issue; obligations to be redeemed are generally chosen by lot. Additionally,
the size and composition of the Fund will be affected by the level of
redemptions of Units that may occur from time to time and the consequent sale of
Debt Obligations (see How to Sell--Redemption). Principally, this will depend
upon the number of Holders seeking to sell or redeem their Units and whether or
not the Sponsors continue to reoffer Units acquired by them in the secondary
market. Factors that the Sponsors will consider in the future in determining to
cease offering Units acquired in the secondary market include, among other
things, the diversity of the Portfolio remaining at that time, the size of the
Fund relative to its original size, the ratio of Fund expenses to income, the
Fund's current and long-term returns, the degree to which Units may be selling
at a premium over par relative to other funds sponsored by the Sponsors and the
cost of maintaining a current prospectus for the Fund. These factors may also
lead the Sponsors to seek to terminate the Fund earlier than would otherwise be
the case (see Trust Indenture).
 
LIQUIDITY
 
     Certain of the Debt Obligations may have been guaranteed or similarly
secured by insurance companies or other corporations or entities. The guarantee
or similar commitment may constitute a security (a 'Restricted Security') that
cannot, in the opinion of counsel, be sold publicly by the Trustee without
registration under the Securities Act of 1933, as amended, or similar provisions
of law subsequently enacted. The Sponsors nevertheless believe that, should a
sale of these Debt Obligations be necessary in order to meet redemption, the
Trustee should be able to consummate a sale with institutional investors. Up to
40% of the Portfolio may consist of Debt Obligations purchased from various
banks and thrifts and other Debt Obligations with guarantees which may
constitute Restricted Securities.
 
     The Portfolio may contain certain Debt Obligations purchased directly from
issuers. These Debt Obligations are generally issued under bond resolutions or
trust indentures providing for the issuance of bonds in publicly saleable
denominations (usually $100,000), may be sold free of the registration
requirements of the Securities Act of 1933 and are otherwise structured in
contemplation of ready marketability. In addition, the Sponsors generally obtain
letters of intention to repurchase or to use best efforts to remarket these Debt
Obligations from the issuers, the placement agents acting in connection with
their sale or the entities providing the additional credit support, if
 
                                       15
<PAGE>
any. These letters do not express legal obligations; however, in the opinion of
the Sponsors, these Debt Obligations should be readily marketable.
 
TAX EXEMPTION
 
     In the opinion of bond counsel rendered on the date of issuance of each
Debt Obligation, the interest on each Debt Obligation is excludable from gross
income under existing law for regular Federal income tax purposes (except in
certain circumstances depending on the Holder) but may be subject to state and
local taxes and may be a preference item for purposes of the Alternative Minimum
Tax (see Portfolio in Part A; Taxes below). As discussed under Taxes below,
interest on some or all of the Debt Obligations may become subject to regular
Federal income tax, perhaps retroactively to their date of issuance, as a result
of changes in Federal law or as a result of the failure of issuers (or other
users of the proceeds of the Debt Obligations) to comply with certain ongoing
requirements.
 
     Moreover, the Internal Revenue Service has announced an expansion of its
examination program with respect to tax-exempt bonds. The expanded examination
program will consist of, among other measures, increased enforcement against
abusive transactions, broader audit coverage (including the expected issuance of
audit guidelines) and expanded compliance achieved by means of expected
revisions to the tax-exempt bond information return forms. At this time, it is
uncertain whether the tax exempt status of any of the Debt Obligations would be
affected by such proceedings, or whether such effect, if any, would be
retroactive.
 
     In certain cases, a Debt Obligation may provide that if the interest on the
Debt Obligation should ultimately be determined to be taxable, the Debt
Obligation would become due and payable by its issuer, and, in addition, may
provide that any related letter of credit or other security could be called upon
if the issuer failed to satisfy all or part of its obligation. In other cases,
however, a Debt Obligation may not provide for the acceleration or redemption of
the Debt Obligation or a call upon the related letter of credit or other
security upon a determination of taxability. In those cases in which a Debt
Obligation does not provide for acceleration or redemption or in which both the
issuer and the bank or other entity issuing the letter of credit or other
security are unable to meet their obligations to pay the amounts due on the Debt
Obligation as a result of a determination of taxability, the Trustee would be
obligated to sell the Debt Obligation and, since it would be sold as a taxable
security, it is expected that it would have to be sold at a substantial discount
from current market price. In addition, as mentioned above, under certain
circumstances Holders could be required to pay income tax on interest received
prior to the date on which the interest is determined to be taxable.
 
HOW TO BUY
 
     Units are available from any of the Underwriters and other broker-dealers
at the Public Offering Price (including the applicable sales charge) plus a
proportionate share of any cash held by the Fund in the Capital Account (unless
allocated to the purchase of specific securities) and net accrued and
undistributed interest. Because both the value of Securities and accrued
interest change, the Public Offering Price varies each Business Day.
 
PUBLIC OFFERING PRICE
 
     In the initial offering period, the Public Offering Price is based on the
next offer side evaluation of the Securities, and includes a sales charge based
on the number of Units of a single Fund or Trust purchased on the same or any
preceding day by a single purchaser. See Initial Offering Sales Charge Schedule
in Appendix B. The purchaser or his dealer must notify the Sponsors at the time
of purchase of any previous purchase to be aggregated and supply sufficient
information to permit confirmation of eligibility; acceptance of the purchase
order is subject to such confirmation. Purchases of Fund Units may not be
aggregated with purchases of any other unit trust. This procedure may be amended
or terminated at any time without notice.
 
     In the secondary market (after the initial offering period), the Public
Offering Price is based on the next bid side evaluation of the Securities, and
includes a sales charge based (a) on the number of Units of the Fund and any
other Series of Municipal Investment Trust Fund purchased in the secondary
market on the same day by a single purchaser (see Secondary Market Sales Charge
Schedule in Appendix B) and (b) the maturities of the underlying Securities (see
Effective Sales Charge in Appendix B). To qualify for a reduced sales charge,
the dealer must confirm that the sale is to a single purchaser or is purchased
for its own account and not for distribution. For these purposes, Units held in
the name of the purchaser's spouse or child under 21 years of age are deemed to
be purchased by a single purchaser. A trustee or other fiduciary purchasing
securities for a single trust estate or single fiduciary account is also
considered a single purchaser.
 
                                       16
<PAGE>
     In the secondary market, the Public Offering Price is further reduced
depending on the maturities of the various bonds in the Portfolio, by
determining a sales charge percentage for each bond, as stated in Effective
Sales Charge in Appendix B. The sales charges so determined, multiplied by the
bid side evaluation of the Securities, are aggregated and the total divided by
the number of Units outstanding to determine the Effective Sales Charge. On any
purchase, the Effective Sales Charge is multiplied by the applicable secondary
market sales charge percentage (depending on the number of Units purchased) in
order to determine the sales charge component of the Public Offering Price.
 
     Employees of certain Sponsors and Sponsor affiliates and non-employee
directors of Merrill Lynch & Co. Inc. may purchase Units at any time at prices
including a sales charge of not less than $5 per Unit.
 
SECURITIES EVALUATIONS
 
     The Public Offering Price is based on the evaluation of Securities in the
Fund, at the offer or bid side as described above, at the Evaluation Time next
following receipt of the order. Evaluations are determined by the Evaluator as
described under Redemption on each Business Day (this excludes Saturdays,
Sundays and the following holidays as observed by the New York Stock Exchange:
New Year's Day, Washington's Birthday, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving and Christmas).
 
ACCRUED INTEREST
 
     Net accrued interest is added to the Public Offering Price, the Sponsors'
Repurchase Price and the Redemption Price per Unit. This represents the interest
accrued on the Securities, net of Fund expenses, from the Initial Date of
Deposit to, but not including, the settlement date for Units (less any prior
distributions of interest income to Holders). Securities deposited also carry
accrued but unpaid interest up to the Initial Date of Deposit. To avoid having
Holders pay this additional accrued interest (which earns no return) when they
purchase Units, the Trustee advances and distributes this amount to the
Sponsors; it recovers this advance from interest received on the Debt
Obligations. Because of varying interest payment dates on the Securities,
accrued interest at any time will exceed the interest actually received by the
Fund.
 
CERTIFICATES
 
     Certificates for Units are issued upon request, and are transferable upon
payment of any taxes or governmental charges and compliance with the
requirements for redeeming Certificates (see Redemption). Certain Sponsors
collect additional charges for registering and shipping Certificates to
purchasers. Lost or mutilated Certificates can be replaced upon delivery of
satisfactory indemnity and payment of costs.
 
COMPARISON OF PUBLIC OFFERING PRICE, SPONSORS' INITIAL REPURCHASE PRICE,
SECONDARY MARKET REPURCHASE PRICE AND REDEMPTION PRICE
 
     On the business day prior to the Initial Date of Deposit the Public
Offering Price per Unit (which includes the sales charge) and the Sponsors'
Initial Repurchase Price per Unit (each based on the offer side evaluation of
the Securities in the Fund--see above) exceeded the Sponsors' Repurchase Price
and the Redemption Price per Unit (each based on the bid side evaluation
thereof--see How to Sell--Redemption) by the amounts set forth under the
Investment Summary.
 
     The initial Public Offering Price per Unit of the Trust and the Initial
Repurchase Price are based on the offer side evaluations of the Securities. The
secondary market Public Offering Price and the Sponsors' Repurchase Price in the
secondary market are based on bid side evaluations of the Securities. In the
past, the bid prices of publicly offered tax-exempt issues have been lower than
the offer prices by as much as 3 1/2% or more of face amount in the case of
inactively traded issues and as little as  1/2 of 1% in the case of actively
traded issues, but the difference between the offer and bid prices has averaged
between 1 and 2% of face amount; the difference on the day before the date of
this Prospectus is stated in a note to the Portfolio.
 
HOW TO SELL
 
SPONSORS' MARKET FOR UNITS
 
     Holders can cash in Units at any time without a fee. The Sponsors (although
not obligated to do so) normally repurchase any Units offered for sale, at the
repurchase price next computed after receipt of the order. Because of the sales
charge and fluctuations in the market value of the Securities (among other
reasons) the repurchase price may be less than the investor's cost for the
Units. Holders disposing of Units should consult their financial
 
                                       17
<PAGE>
professional as to current market prices to determine if other broker-dealers or
banks offer higher prices for those Units.
 
     The Sponsors may discontinue this market without prior notice if the supply
of Units exceeds demand or for other business reasons; in that event, the
Sponsors may still purchase Units at the redemption price as a service to
Holders. Although the Sponsors may reoffer Units repurchased, alternatively they
may redeem those Units; see Redemption for a description of certain consequences
of redemptions to remaining Holders.
 
REDEMPTION
 
     Holders may redeem Units by tendering to the Trustee Certificates (if
issued) or a request for redemption. Certificates must be properly endorsed or
accompanied by a written transfer instrument. Each Holder must sign the
Certificate, transfer instrument or request exactly as the name appears on the
face of the Certificate; signatures must be guaranteed by an eligible guarantor
institution or in another manner acceptable to the Trustee. In certain
instances, additional documents may be required such as a certificate of death,
trust instrument, certificate of corporate authority or appointment as executor,
administrator or guardian. If the Sponsors are maintaining a market for Units,
they will purchase any Units tendered at the price described in the preceding
section. If the Sponsors do not purchase Units tendered, the Trustee is
authorized in its discretion to sell Units in the over-the-counter market if it
believes it will obtain for the redeeming Holder a higher net price.
 
     Redemptions may be suspended or payment postponed in limited circumstances:
(1) if the New York Stock Exchange is closed other than for customary weekend
and holiday closings; (2) if the SEC determines that trading on that Exchange is
restricted or an emergency exists making disposal or evaluation of the
Securities not reasonably practicable; or (3) for any other period which the SEC
by order permits.
 
     On the seventh calendar day after tender (the preceding Business Day if the
seventh day is not a Business Day), the Holder will be mailed an amount per Unit
equal to the Redemption Price Per Unit at the Evaluation Time next following
receipt of the tender. As noted above, this price may be more or less than the
cost of those Units.
 
     Redemption Price per Unit is computed each Business Day by adding (a) the
aggregate bid side evaluation of the Securities, (b) cash in the Fund (excluding
cash held to pay contracts to purchase Securities or in a reserve account), (c)
accrued but unpaid interest on the Securities up to but not including the
payment date and (d) the aggregate value of any other Fund assets; deducting (v)
unpaid taxes or other governmental charges, (w) accrued but unpaid Fund
expenses, (x) unreimbursed Trustee advances, (y) cash held to redeem Units or
for distribution to Holders and (z) the aggregate value of any other Fund
liabilities; and dividing the result by the Units outstanding as of the
computation. Evaluations of Securities are determined by the Evaluator as
follows: During the initial syndicate offering period for any Debt Obligation,
its evaluation will be at the syndicate offer price unless the Evaluator
determines that this price does not accurately reflect the market value. For
Securities traded over-the-counter, the evaluation is generally based on the
closing sales prices on that market (unless the Evaluator deems these prices
inappropriate for valuation). If closing sales prices are not available, the
evaluation is generally determined on the basis of current bid or offer prices
for the Securities or (if not available) for comparable securities or by
appraising the value or any combination of these methods.
 
     The value of any insurance is reflected in the market value of any Insured
Debt Obligation. The Sponsors believe that this is a fair method of valuing the
Insured Debt Obligations and the insurance.
 
     If cash is not available in the Fund's Income and Capital Accounts to pay
redemptions, the Trustee is authorized to sell Securities. Securities to be sold
will be selected by the Agent for the Sponsors in accordance with procedures
specified in the Indenture, based on market and credit factors that they
determine are in the best interests of the Fund. The Sponsors are authorized to
specify minimum face amounts in which Securities are sold, to obtain a better
price for the Fund. When Securities are sold (or mature or are called), the size
and diversity of the Fund is reduced. Sales to meet redemptions are often made
at times when Securities would not otherwise be sold, and may result in lower
prices than might be realized otherwise.
 
INCOME AND DISTRIBUTIONS
 
INCOME
 
     Income is received by the Fund upon semi-annual payments of interest on the
Debt Obligations held in the Portfolio. Some of the Debt Obligations may be
purchased on a when, as and if issued basis or may have a
 
                                       18
<PAGE>
delayed delivery (see Portfolio). Since interest on these Debt Obligations does
not begin to accrue until the date of delivery to the Fund, in order to provide
tax-exempt income to the Holders for this non-accrual period, the Trustee's
Annual Fee and Expenses is reduced by the interest that would have accrued on
these Debt Obligations between the initial settlement date for Units and the
delivery dates of the Debt Obligations. This eliminates reduction in Monthly
Income Distributions. Should when-issued Debt Obligations be issued later than
expected, the fee reduction will be increased correspondingly. If the amount of
the Trustee's Annual Fee and Expenses is insufficient to cover the additional
accrued interest, the Sponsors will treat the contracts as Failed Debt
Obligations. As the Trustee is authorized to draw on the letter of credit
deposited by the Sponsors before the settlement date for these Debt Obligations
and deposit the proceeds in an account for the Fund on which it pays no
interest, its use of these funds compensates the Trustee for the reduction
described above.
 
RETURNS
 
     Estimated Current Return represents annual cash to be received from
interest-bearing Debt Obligations in the Portfolio (net of estimated annual
expenses) divided by the Public Offering Price (including sales charge).
 
     Estimated Long-Term Return is a measure of the estimated return earned over
the estimated life of the Fund. This represents an average of the yields to
maturity (or earliest call date for obligations trading at a premium over the
call price) of the Debt Obligations in the Portfolio, calculated in accordance
with accepted bond practice and adjusted to reflect expenses and sales charges.
Bonds are customarily offered on a 'yield price' basis, which reflects
computation of yield to maturity (or call date) and not only the interest
payable but amortization or accretion to a specified date of any premium over or
discount from par (maturity) value in the bond's purchase price. In calculating
Estimated Long Term Return, the average yield for the Portfolio is derived by
weighing each Debt Obligation's yield by its market value and the time remaining
to the date to which the Debt Obligation is priced. The average Portfolio yield
so computed is adjusted to reflect estimated expenses and the maximum sales
charge. This calculation does not reflect certain delays in distributing income
nor the timing of other receipts and distributions on Units; depending on
maturities, it may therefore overstate or understate the impact of sales
charges. Both of these factors may result in a lower figure.
 
     Both Estimated Current Return and Estimated Long Term Return can fluctuate
with changes in Portfolio composition, in market value of the Debt Obligations,
in Fund expenses and sales charges; these returns therefore can vary materially
from the figures at the time of purchase. Any difference between Estimated
Current Return and Estimated Long Term Return will probably fluctuate at least
as frequently. These figures may not be directly comparable to yield figures
used to measure other investments, and since the estimated returns are based on
various assumptions and variables, returns received by Holders may be higher or
lower.
 
FUND ACCOUNTS
 
     Interest received is credited to an Income Account and other receipts to a
Capital Account. A Reserve Account may be created by withdrawing from the Income
or Capital Accounts amounts considered appropriate by the Trustee to reserve for
any material amount that may be payable out of the Fund. Monies held by the
Trustee in the various accounts for the Fund do not bear interest.
 
DISTRIBUTIONS
 
     The initial estimated net annual interest rate per Unit is stated in
Investment Summary. This is based on $1,000 face amount per Unit, after
deducting estimated annual Fund expenses. The rate will change as Securities
mature, are called or sold or otherwise disposed of, as Replacement Securities
are deposited and as Fund expenses change. Because the Portfolio is not actively
managed, income distributions may not be affected by changes in interest rates.
Subject to the financial conditions of the issuers of the Securities, the amount
of income should be substantially maintained as long as the Portfolio remains
unchanged; however, optional bond redemptions or other Portfolio changes may
occur more frequently when interest rates decline, which would result in early
return of principal.
 
     Each Unit receives an equal share of monthly distributions of interest
income and any principal distributed, substantially equal to the proportionate
income during the month preceding the Record Day less estimated expenses.
Interest on the Debt Obligations is received by the Fund on a semi-annual or
annual basis. Therefore, it takes several months after the Initial Date of
Deposit for the Trustee to receive sufficient interest payments on the
Securities to begin distributions to Holders; see Investment Summary for
estimates of the first and following Monthly Income Distributions. When a
Security is sold, redeemed or otherwise disposed of, accrued interest is
 
                                       19
<PAGE>
received by the Fund. Further, because interest on the Securities is not
received by the Fund at a constant rate throughout the year, any Monthly Income
Distribution may be more or less than the interest actually received. To
eliminate fluctuations in the Monthly Income Distribution, the Trustee will
advance amounts necessary to provide approximately equal distributions; it will
be reimbursed, without interest, from interest received on the Securities.
However, the amount of Monthly Income Distributions will change over time as
described above.
 
     Along with the Monthly Income Distributions, the Trustee will distribute
the Holder's pro rata share of the distributable cash balance of the Capital
Account, computed as of the close of business on the preceding Record Day (if at
least equal to the Minimum Capital Distribution stated in Investment Summary).
Principal proceeds received from disposition of any Security after a Record Day
and prior to the related Distribution Day will be held in the Capital Account
subject to distribution on the second following Distribution Day. The first
distribution for a purchaser of Units between a Record Day and the related
Distribution Day will be made on the second following Distribution Day.
 
     Any funds held to acquire Replacement Securities which have not been used
to purchase Securities within 90 days after the initial deposit, unless promptly
used to purchase Replacement Securities, will be distributed to Holders together
with the attributable sales charge and interest attributable to those funds.
This interest will not be exempt from tax.
 
INVESTMENT ACCUMULATION PROGRAM
 
     Distributions of interest and any principal or premium received by the Fund
will be paid in cash unless the Holder elects to have these distributions
reinvested without sales charge in the Municipal Fund Accumulation Program, Inc.
(the 'Program'). The Program is an open-end management investment company whose
investment objective is to obtain income that is exempt from regular Federal
income taxes through investment in a diversified portfolio consisting primarily
of state, municipal and public authority debt obligations rated A or better or
with comparable credit characteristics. Reinvesting compounds earnings free from
Federal tax. Holders participating in the Program will be subject to State and
local income taxes to the same extent as if the distributions had been received
in cash, and most of the income on the Program is subject to State and local
income taxes. For more complete information about the Program, including charges
and expenses, return the enclosed form for a prospectus. Read it carefully
before you decide to participate. Notice of election to participate must be
received by the Trustee in writing at least ten days before the Record Day for
the first distribution to which the notice is to apply.
 
FUND EXPENSES
 
     See Trustee's Annual Fee and Expenses under Investment Summary for
estimated annual Fund expenses; if actual expenses exceed the estimate, the
excess will be borne by the Fund. The annual fee solely for the Trustee's
services is $0.70 per $1,000 face amount of Debt Obligations, payable in monthly
installments. The Trustee also benefits when it holds cash for the Fund in
non-interest bearing accounts. Possible additional charges include Trustee fees
and expenses for extraordinary services, costs of indemnifying the Trustee and
the Sponsors to the extent permitted by law and the Indenture, costs of action
taken to protect the Fund and other legal fees and expenses, Fund termination
expenses and any governmental charges. The Trustee has a lien on Fund assets to
secure reimbursement of these amounts, and may sell Securities for this purpose.
The Sponsors receive an annual fee for Portfolio supervisory services at the
maximum stated under Investment Summary, based on the initial face amount in any
calendar year. While this may exceed their costs of providing these services to
the Fund, the total supervision fees from all Municipal Investment Trust Fund
Series will not exceed their costs for these services to all of those Series
during any calendar year. The Sponsors may also be reimbursed for their costs of
providing bookkeeping and administrative services to the Fund. The Trustees's,
Sponsors' and Evaluators fees may be adjusted for inflation without Holders'
approval.
 
LOW COSTS
 
     All expenses in establishing the Fund, including the cost of the initial
preparation and printing of documents relating to the Fund, cost of the initial
evaluation, the initial fees and expenses of the Trustee, legal expenses,
advertising and selling expenses and any other out-of-pocket expenses, will be
paid from the Underwriting Account at no charge to the Fund.
 
     Sales charges on Defined Asset Funds range from under 1.0% to 5.5%. This
may be less than you might pay to buy a comparable mutual fund. Defined Asset
Funds have no 12b-1 or back-end load fees. These Funds can be
 
                                       20
<PAGE>
a cost-effective way to purchase and hold investments. Annual operating expenses
are generally lower than for managed funds. Because Defined Funds have no
management fees, limited transaction costs and no ongoing marketing expenses,
operating expenses are generally less than 0.25% a year. When compounded
annually, small differences in expense ratios can make a big difference in
expenses.
 
EXCHANGE OPTION
 
     Holders may exchange Units (except of Short Intermediate Series) at a
reduced sales charge for units of one or more series of the types listed in
Appendix C ('Exchange Funds'). This includes the current maximum sales charge
and exchange fee for each type of Exchange Fund. (If units held less than five
months are exchanged for a series with a higher regular sales charge, the Holder
will pay the difference between the sales charges paid on the units exchanged
and the regular sales charge for the units acquired, if greater than the
exchange fee.)
 
      The current return from taxable fixed income securities is normally higher
than that available from tax exempt fixed income securities. Certain of the
Exchange Funds do not provide for periodic payments of interest and are best
suited for purchase by IRA's, Keogh plans, pension funds or other tax-deferred
retirement plans. Consequently, some of the Exchange Funds may be inappropriate
investments for some Holders. Appendix C lists certain characteristics of each
type of Exchange Fund which a Holder should consider in determining whether it
would be an appropriate investment and therefore an appropriate exchange for
Units of the Fund.
 
     Holders of Exchange Funds can similarly exchange units of those funds for
Units of the Fund. However, units of series offered at a maximum applicable
sales charge below 3.50% of the public offering price (including certain series
of Exchange Funds listed in Appendix C) are not eligible for exchange except
that Holders may exchange Units of the Fund for Freddie Mac or Select Ten Series
during their initial offering periods. Holders of other registered unit
investment trusts originally offered at a maximum applicable sales charge of at
least 3.0% ('Conversion Trusts') may similarly acquire Units at the exchange
fee.
 
     To make an exchange, a Holder should contact his financial professional to
find out what suitable Exchange Funds are available and to obtain a prospectus.
The Holder may only acquire units of an Exchange Fund in which the Sponsors
maintain a secondary market and which are lawfully available for sale in the
state where the Holder resides. Except for the sales charge, an exchange is like
any other purchase and sale of units in the secondary market. An exchange is a
taxable event normally requiring recognition of any gain or loss on the units
exchanged. However, the Internal Revenue Service may seek to disallow a loss if
the portfolio of the units acquired is not materially different from the
portfolio of the units exchanged; Holders should consult their own tax advisers.
If the proceeds of units exchanged is insufficient to acquire a whole number of
Exchange Fund units, the Holder may pay the difference in cash (not exceeding
the price of a single unit acquired).
 
     As the Sponsors are not obligated to maintain a secondary market in any
series, there can be no assurance that units of a desired series will be
available for exchange. The Exchange Option may be amended or terminated by the
Sponsors at any time, without notice to Holders.
 
TAXES
 
     The following discussion addresses only the tax consequences of Units held
as capital assets and does not address the tax consequences of Units held by
dealers, financial institutions or insurance companies.
 
     In the opinion of Davis Polk & Wardwell, special counsel for the Sponsors,
under existing law:
 
        The Fund is not an association taxable as a corporation for Federal
     income tax purposes, and income received by the Fund will be treated as the
     income of the Holders in the manner set forth below.
 
        Each Holder will be considered the owner of a pro rata portion of each
     Debt Obligation in the Fund under the grantor trust rules of Sections
     671-679 of the Internal Revenue Code of 1986, as amended (the 'Code'). In
     order to determine the face amount of a Holder's pro rata portion of each
     Debt Obligation on the Initial Date of Deposit, see Face Amount under
     Portfolio. The total cost to a Holder of his Units, including sales
     charges, is allocated to his pro rata portion of each Debt Obligation, in
     proportion to the fair market values thereof on the date the Holder
     purchases his Units, in order to determine his tax basis for his pro rata
     portion of each Debt Obligation. In order for a Holder who purchases his
     Units on the Initial Date of Deposit to determine the fair market value of
     his pro rata portion of each Debt Obligation on such date, see Cost of Debt
     Obligations to Fund under Portfolio.
 
                                       21
<PAGE>
        Each Holder will be considered to have received the interest on his pro
     rata portion of each Debt Obligation when interest on the Debt Obligation
     is received by the Fund. In the opinion of bond counsel (delivered on the
     date of issuance of the Debt Obligation), such interest will be excludable
     from gross income for regular Federal income tax purposes (except in
     certain limited circumstances referred to below). Amounts received by the
     Fund pursuant to a bank letter of credit, guarantee or insurance policy
     with respect to payments of principal, premium or interest on a Debt
     Obligation will be treated for Federal income tax purposes in the same
     manner as if such amounts were paid by the issuer of the Debt Obligation.
 
        The Fund may contain Debt Obligations which were originally issued at a
     discount ('original issue discount'). The following principles will apply
     to each Holder's pro rata portion of any Debt Obligation originally issued
     at a discount. In general, original issue discount is defined as the
     difference between the price at which a debt obligation was issued and its
     stated redemption price at maturity. Original issue discount on a
     tax-exempt obligation issued after September 3, 1982 is deemed to accrue as
     tax-exempt interest over the life of the obligation under a formula based
     on the compounding of interest. Original issue discount on a tax-exempt
     obligation issued before July 2, 1982 is deemed to accrue as tax-exempt
     interest ratably over the life of the obligation. Original issue discount
     on any tax-exempt obligation issued during the period beginning July 2,
     1982 and ending September 3, 1982 is also deemed to accrue as tax-exempt
     interest over the life of the obligation, although it is not clear whether
     such accrual is ratable or is determined under a formula based on the
     compounding of interest. If a Holder's tax basis for his pro rata portion
     of a Debt Obligation issued with original issue discount is greater than
     its 'adjusted issue price' but less than its stated redemption price at
     maturity (as may be adjusted for certain payments), the Holder will be
     considered to have purchased his pro rata portion of the Debt Obligation at
     an 'acquisition premium'. A Holder's adjusted tax basis for his pro rata
     portion of the Debt Obligation issued with original issue discount will
     include original issue discount accrued during the period such Holder held
     his Units. Such increases to the Holder's tax basis in his pro rata portion
     of the Debt Obligation resulting from the accrual of original issue
     discount, however, will be reduced by the amount of any such acquisition
     premium.
 
        If a Holder's tax basis for his pro rata portion of a Debt Obligation
     exceeds the redemption price at maturity thereof (subject to certain
     adjustments), the Holder will be considered to have purchased his pro rata
     portion of the Debt Obligation with 'amortizable bond premium'. The Holder
     is required to amortize such premium over the term of the Debt Obligation.
     Such amortization is only a reduction of basis for his pro rata portion of
     the Debt Obligation and does not result in any deduction against the
     Holder's income. Therefore, under some circumstances, a Holder may
     recognize taxable gain when his pro rata portion of a Debt Obligation is
     disposed of for an amount equal to or less than his original tax basis
     therefor.
 
        A Holder will recognize taxable gain or loss when all or part of his pro
     rata portion of a Debt Obligation is disposed of by the Fund for an amount
     greater or less than his adjusted tax basis. Any such taxable gain or loss
     will be capital gain or loss, except that any gain from the disposition of
     a Holder's pro rata portion of a Debt Obligation acquired by the Holder at
     a 'market discount' (i.e., where the Holder's original tax basis for his
     pro rata portion of the Debt Obligation (plus any original issue discount
     which will accrue thereon until its maturity) is less than its stated
     redemption price at maturity) would be treated as ordinary income to the
     extent the gain does not exceed the accrued market discount. Capital gains
     are generally taxed at the same rate as ordinary income. However, the
     excess of net long-term capital gains over net short-term capital losses
     may be taxed at a lower rate than ordinary income for certain noncorporate
     taxpayers. A capital gain or loss is long-term if the asset is held for
     more than one year and short-term if held for one year or less. The
     deduction of capital losses is subject to limitations. A Holder will also
     be considered to have disposed of all or part of his pro rata portion of
     each Debt Obligation when he sells or redeems all or some of his Units.
 
        Under Section 265 of the Code, a Holder (except a corporate Holder) is
     not entitled to a deduction for his pro rata share of fees and expenses of
     the Fund, because the fees and expenses are incurred in connection with the
     production of tax-exempt income. Further, if borrowed funds are used by a
     Holder to purchase or carry Units of the Fund, interest on this
     indebtedness will not be deductible for Federal income tax purposes. In
     addition, under rules used by the Internal Revenue Service, the purchase of
     Units may be considered to have been made with borrowed funds even though
     the borrowed funds are not directly traceable to the purchase of Units.
 
        Under the income tax laws of the State and City of New York, the Fund is
     not an association taxable as a corporation and income received by the Fund
     will be treated as the income of the Holders in the same manner as for
     Federal income tax purposes, but will not necessarily be tax-exempt.
 
                                       22
<PAGE>
        Holders will be taxed in the manner described above regardless of
     whether the distributions from the Fund are actually received by the
     Holders or are automatically reinvested in the Municipal Fund Accumulation
     Program, Inc.
 
        From time to time proposals are introduced in Congress and state
     legislatures which, if enacted into law, could have an adverse impact on
     the tax-exempt status of the Debt Obligations. It is impossible to predict
     whether any legislation in respect of the tax status of interest on the
     Debt Obligations may be proposed and eventually enacted at the Federal or
     state level.
 
        The foregoing discussion relates only to Federal and certain aspects of
     New York State and City income taxes. Depending on their state of
     residence, Holders may be subject to state and local taxation and should
     consult their own tax advisers in this regard.
 
                                    *  *  *
 
     The Fund may include Debt Obligations issued after August 7, 1986 (see
Investment Summary--Taxation and Portfolio in Part A). Interest (including any
original issue discount) on certain of these Debt Obligations will be a
preference item for purposes of the alternative minimum tax ('AMT'). In
addition, a corporate Holder should be aware that the accrual or receipt of
tax-exempt interest not subject to the AMT may give rise to an alternative
minimum tax liability (or increase an existing liability) because the interest
income will be included in the corporation's 'adjusted current earnings' for
purposes of the adjustment to alternative minimum taxable income required by
Section 56(g) of the Code, and will be taken into account for purposes of the
environmental tax on corporations under Section 59A of the Code, which is based
on alternative minimum taxable income. In addition, interest on the Debt
Obligations must be taken into consideration in computing the portion, if any,
of social security benefits that will be included in an individual's gross
income and subject to Federal income tax. Holders are urged to consult their own
tax advisers concerning an investment in Units.
 
     At the time of issuance of each Debt Obligation, an opinion relating to the
validity of the Debt Obligation and to the exemption of interest thereon from
regular Federal income taxes was or will be rendered by bond counsel. Neither
the Sponsors nor Davis Polk & Wardwell have made or will make any review of the
proceedings relating to the issuance of the Debt Obligations or the basis for
these opinions. The tax exemption is dependent upon the issuer's (and other
users') compliance with certain ongoing requirements, and the opinion of bond
counsel assumes that these requirements will be complied with. However, there
can be no assurance that the issuer (and other users) will comply with these
requirements, in which event the interest on the Debt Obligation could be
determined to be taxable retroactively from the date of issuance.
 
     In the case of certain Debt Obligations, the opinions of bond counsel
indicate that interest on these Debt Obligations received by a 'substantial
user' of the facilities being financed with the proceeds of such Debt
Obligations, or persons related thereto, for periods while such Debt Obligations
are held by such a user or related person, will not be exempt from regular
Federal income taxes, although interest on such Debt Obligations received by
others would be exempt from regular Federal income taxes. 'Substantial user' is
defined under U.S. Treasury Regulations to include only a person whose gross
revenue derived with respect to the facilities financed by the issuance of bonds
is more than 5% of the total revenue derived by all users of these facilities,
or who occupies more than 5% of the usable area of these facilities or for whom
these 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.
 
     After the end of each calendar year, the Trustee will furnish to each
Holder an annual statement containing information relating to the interest
received by the Fund on the Debt Obligations, the gross proceeds received by the
Fund from the disposition of any Debt Obligation (resulting from redemption or
payment at maturity of any Debt Obligation or the sale by the Fund of any Debt
Obligation), and the fees and expenses paid by the Fund. The Trustee will also
furnish annual information returns to each Holder and to the Internal Revenue
Service. Holders are required to report to the Internal Revenue Service the
amount of tax-exempt interest received during the year.
 
ADMINISTRATION OF THE FUND
 
RECORDS
 
     The Trustee keeps a register of the names, addresses and holdings of all
Holders. The Trustee also keeps records of the transactions of the Fund,
including a current list of the Securities and a copy of the Indenture, which
may be inspected by Holders at reasonable times during business hours.
 
                                       23
<PAGE>
REPORTS TO HOLDERS
 
     With each distribution, the Trustee includes a statement of the interest
and any other receipts being distributed. Within five days after deposit of Debt
Obligations in exchange or substitution for Debt Obligations (or contracts)
previously deposited, the Trustee will send a notice to each Holder, identifying
both the Debt Obligations removed and the Replacement Securities deposited. The
Trustee sends each record Holder an annual report summarizing transactions in
the Fund's accounts and amounts distributed during the year and Securities held,
number of Units outstanding and Redemption Price at year end, among other
matters. Holders may obtain copies of Securities evaluations from the Trustee to
enable them to comply with Federal and state tax reporting requirements. Fund
accounts are audited annually by independent accountants selected by the
Sponsors; audited financial statements are available on request.
 
TRUST INDENTURE
 
     The Fund is a 'unit investment trust' created under New York law by a Trust
Indenture (the 'Indenture') among the Sponsors, the Trustee and the Evaluator.
This Prospectus summarizes various provisions of the Indenture, but each
statement herein is qualified in its entirety by reference to the Indenture.
 
     The Indenture may be amended by the Sponsors and the Trustee, without
consent by Holders: (a) to cure ambiguities or to correct or supplement any
defective or inconsistent provision, (b) to make any amendment required by the
SEC or other governmental agency, or (c) to make any other change not materially
adverse to the interest of Holders (as determined in good faith by the
Sponsors). The Indenture may also be amended upon consent of Holders of 51% of
the Units. No amendment may reduce the interest of any Holder in the Fund
without the Holder's consent or reduce the percentage of Units required to
consent to any amendment without unanimous consent of Holders. Holders will be
notified on the substance of any amendment.
 
     The Fund will be terminated, and any remaining Securities sold, no later
than the mandatory termination date specified in Investment Summary. It will
terminate earlier upon the disposition of the last Security, upon direction of
the Sponsors if total assets are below the minimum value specified in Investment
Summary or upon consent of Holders of 51% of the Units. The Trustee will notify
each Holder in writing within a reasonable time before termination, specifying
when Certificates should be surrendered. After termination, the Trustee will
sell any remaining Securities and distribute (by check mailed to the Holder)
each Holder's pro rata interest in the Fund, net of any unpaid fees, taxes,
governmental and other charges and subject to surrender of any outstanding
Certificate by the Holder.
 
     Merrill Lynch, Pierce, Fenner & Smith Incorporated has been appointed as
Agent for the Sponsors by the other Sponsors.
 
     The Trustee may resign upon notice to the Sponsors; it may be removed by
direction of Holders of 51% of the Units at any time or by the Sponsors without
consent of Holders if it becomes incapable of acting or bankrupt, its affairs
are taken over by public authorities, or if for any reason the Sponsors
determine in good faith that its replacement is in the best interest of the
Holders. The Evaluator may resign or be removed by the Sponsors and the Trustee
without consent of Holders. The resignation or removal of either becomes
effective upon acceptance of appointment by a successor; in this case, the
Sponsors (and the Trustee in the case of a successor Evaluator) will use their
best efforts to appoint a successor promptly; however, if upon resignation no
successor has accepted appointment within 30 days after notification, the
resigning Trustee or Evaluator may apply to a court of competent jurisdiction to
appoint a successor.
 
     Any Sponsor may resign if one remaining Sponsor maintains a net worth of
$2,000,000 and is agreeable to the resignation. A new Sponsor may be appointed
by the remaining Sponsors and the Trustee to assume the duties of the resigning
Sponsor. If there is only one Sponsor and it fails to perform its duties or
becomes incapable of acting or bankrupt or its affairs are taken over by public
authorities, the Trustee may (a) appoint a successor Sponsor at rates of
compensation deemed by the Trustee to be reasonable and not exceeding amounts
prescribed by the SEC, or (b) terminate the Indenture and liquidate the Fund or
(c) continue to act as Trustee without terminating the Indenture.
 
     The Sponsors, the Trustee and the Evaluator are not liable to any other
party (including Holders) for any act or omission in the conduct of their
responsibilities absent bad faith, willful misfeasance, negligence (gross
negligence in the case of a Sponsor) or reckless disregard of duty. The Trustee
will not be personally liable for taxes or other governmental charges with
respect to the Securities or interest thereon. The Indenture contains other
customary provisions limiting liability of the Trustee.

AUDITORS
 
     The Statement of Condition in Part A was audited by Deloitte & Touche LLP,
independent accountants, as stated in their opinion. It is included in reliance
upon that opinion given on the authority of that firm as experts in accounting
and auditing.
 
SPONSORS
 
     Each Sponsor is a Delaware corporation and is engaged in the underwriting,
securities and commodities brokerage business and is a member of the New York
Stock Exchange, Inc., other major securities exchanges and commodity exchanges,
and the National Association of Securities Dealers, Inc. Merrill Lynch, Pierce,
Fenner & Smith Incorporated, a subsidiary of Merrill Lynch & Co., Inc., is
engaged in the investment advisory business. Smith Barney Inc., an investment
banking and securities broker-dealer firm, is an indirect wholly-owned
subsidiary of The Travelers Inc. Prudential Securities Incorporated, a
wholly-owned subsidiary of Prudential Securities Group Inc. and an indirectly
wholly-owned subsidiary of the Prudential Insurance Company of America, is
engaged in the investment advisory business. Dean Witter Reynolds Inc., a
principal operating subsidiary of Dean Witter, Discover & Co., is engaged in the
investment advisory business. PaineWebber Incorporated is engaged in the
investment advisory business and is a wholly-owned subsidiary of PaineWebber
Group Inc. Each Sponsor, or one of its predecessor corporations, has acted as
Sponsor of a number of series of unit investment trusts. Each Sponsor has acted
as principal underwriter and managing underwriter of other investment companies.
The Sponsors, in addition to participating as members of various selling groups
or as agents of other investment companies, execute orders on behalf of
investment companies for the purchase and sale of securities of these companies
and sell securities to these companies in their capacities as brokers or dealers
in securities.
 
PUBLIC DISTRIBUTION
 
     On the Initial Date of Deposit, the Sponsors, acting as managers for the
underwriters ('Underwriters') named under Underwriting Account, deposited the
Debt Obligations listed under Portfolio (or purchase contracts for these
Securities together with a letter of credit to complete the purchase), in
exchange for Units representing the entire ownership of the Fund.
 
                                       25
<PAGE>
     During the initial offering period Units will be distributed to the public
at the Public Offering Price through the Underwriting Account and dealers. The
initial offering period is 30 days or less if all Units are sold. If some Units
initially offered have not been sold, the Sponsors may extend the initial
offering period for up to four additional successive 30-day periods. Upon the
completion of the initial offering, Units which remain unsold or were
repurchased may be offered by this Prospectus at the secondary market Public
Offering Price.
 
     The Sponsors intend to qualify Units for sale in all states in which
qualification is deemed necessary through the Underwriting Account and by
dealers who are members of the National Association of Securities Dealers, Inc.
The Sponsors do not intend to qualify Units for sale in any foreign countries
and this Prospectus does not constitute an offer to sell Units in any country
where Units cannot lawfully be sold. Sales to dealers and to introducing
dealers, if any, will initially be made at prices which represent a concession
of the applicable rate specified in Appendix B, but the Agent for the Sponsors
reserves the right to change the rate of the concession to dealers and the
concession to introducing dealers from time to time. Any dealer or introducing
dealer may reallow a concession up to the concession to dealers.
 
UNDERWRITERS' AND SPONSORS' PROFITS
 
     Upon sale of the Units, the Underwriters will receive sales charges at the
rates listed in Appendix B. The Sponsors also realized the profit or loss on
deposit of the Securities stated in Investment Summary. This is the difference
between the cost of the Securities to the Fund (based on the offer side
evaluation of the Securities on the Initial Date of Deposit) and the Sponsors'
cost of the Securities. The amount of any additional fees received in connection
with the direct placement of certain Debt Obligations deposited in the Portfolio
is also stated in Investment Summary. In addition, a Sponsor or Underwriter may
realize profits or sustain losses on Debt Obligations it deposits in the Fund
which were acquired from underwriting syndicates of which it was a member.
During the initial offering period the Underwriting Account also may realize
profits or sustain losses as a result of fluctuations after the Initial Date of
Deposit in the Public Offering Price of the Units (see Investment Summary). In
maintaining a secondary market for Units (see Market for Units), the Sponsors
will also realize profits or sustain losses in the amount of any difference
between the prices at which they buy Units and the prices at which they resell
these Units (which include the sales charge) or the prices at which they redeem
the Units. Cash, if any, made available by buyers of Units to the Sponsors prior
to a settlement date for the purchase of Units may be used in the Sponsors'
businesses to the extent permitted by Rule 15c3-3 under the Securities Exchange
Act of 1934 and may be of benefit to the Sponsors.
 
DEFINED ASSET FUNDS
 
     Each Sponsor (or a predecessor) has acted as Sponsor of various series of
Defined Asset Funds. A subsidiary of Merrill Lynch, Pierce, Fenner & Smith
Incorporated succeeded in 1970 to the business of Goodbody & Co., which had been
a co-Sponsor of Defined Asset Funds since 1964. That subsidiary resigned as
Sponsor of each of the Goodbody series in 1971. Merrill Lynch, Pierce, Fenner &
Smith Incorporated has been co-Sponsor and the Agent for the Sponsors of each
series of Defined Asset Funds created since 1971. Shearson Lehman Brothers Inc.
('Shearson') and certain of its predecessors were underwriters beginning in 1962
and co-Sponsors from 1965 to 1967 and from 1980 to 1993 of various Defined Asset
Funds. As a result of the acquisition of certain of Shearson's assets by Smith
Barney, Harris Upham & Co. Incorporated and The Travelers Inc. (formerly
Primerica Corporation), Smith Barney Inc. now serves as co-Sponsor of various
Defined Asset Funds. Prudential Securities Incorporated and its predecessors
have been underwriters of Defined Asset Funds since 1961 and co-Sponsors since
1964, in which year its predecessor became successor co-Sponsor to the original
Sponsor. Dean Witter Reynolds Inc. and its predecessors have been underwriters
of various Defined Asset Funds since 1964 and co-Sponsors since 1974.
PaineWebber Incorporated and its predecessor have co-Sponsored certain Defined
Asset Funds since 1983.
 
     The Sponsors have maintained secondary markets in Defined Asset Funds for
over 20 years. For decades informed investors have purchased unit investment
trusts for dependability and professional selection of investments. Defined
Asset Funds offers an array of simple and convenient investment choices, suited
to fit a wide variety of personal financial goals--a buy and hold strategy for
capital accumulation, such as for children's education or a nest egg for
retirement, or attractive, regular current income consistent with relative
protection of capital. There are Defined Funds to meet the needs of just about
any investor. Unit investment trusts are particularly suited for the many
investors who prefer to seek long-term profits by purchasing sound investments
and holding them, rather than through active trading. Few individuals have the
knowledge, resources or capital to buy and hold a diversified portfolio on their
own; it would generally take a considerable sum of money to obtain
 
                                       26
<PAGE>
the breadth and diversity offered by Defined Funds. Sometimes it takes a
combination of Defined Funds to plan for your objectives.
 
     One of the most important investment decisions an investor faces may be how
to allocate his investments among asset classes. Diversification among different
kinds of investments can balance the risks and rewards of each one. Most
investment experts recommend stocks for long-term capital growth. Long-term
corporate bonds offer relatively high rates of interest income. By purchasing
both defined equity and defined bond funds, investors can receive attractive
current income, as well as growth potential, offering some protection against
inflation.
 
     The following chart shows the average annual compounded rate of return of
selected asset classes over the 10-year and 20-year periods ending December 31,
1993, compared to the rate of inflation over the same periods. Of course, this
chart represents past performance of these investment categories and there is no
guarantee of future results, either of these categories or of Defined Funds.
Defined Funds also have sales charges and expenses, which are not reflected in
the chart.

     Instead of having to select individual securities on their own, purchasers
of Defined Funds benefit from the expertise of Defined Asset Funds' experienced
buyers and research analysts. In addition, they gain the advantage of
diversification by investing in units of a Defined Fund holding securities of
several different issuers. Such diversification reduces risk, but does not
eliminate it. While the portfolio of managed funds, such as mutual funds,
continually changes, defined bond funds offer a defined portfolio and a schedule
of income distributions defined in the prospectus. Investors know, generally,
when they buy, the issuers, maturities, call dates and ratings of the securities
in the portfolio. Of course, the portfolio may change somewhat over time as
additional securities are deposited, as securities mature or are called or
redeemed or as they are sold to meet redemptions and in the limited other
circumstances. Investors buy bonds for dependability--they know what they can
expect to earn and that principal is distributed as the bonds mature. Investors
also know at the time of purchase their estimated income and current and
long-term returns, subject to credit and market risks and to changes in the
portfolio or the fund's expenses.
 
     Defined Asset Funds offers a variety of fund types. The tax exemption for
municipal bonds, which makes them attractive to high-bracket taxpayers, is
offered by Defined Municipal Investment Trust Funds. Defined Municipal
Investment Trust Funds have provided investors with tax-free income for more
than 30 years. Municipal Defined Funds offer a simple and convenient way for
investors to earn monthly income free from regular Federal income tax. Defined
Corporate Income Funds, with higher current returns than municipal or government
funds, are suitable for Individual Retirement Accounts and other tax-advantaged
accounts and provide investors a simple and convenient way to earn monthly
income. Defined Government Securities Income Funds provide a way to participate
in markets for U.S. government securities while earning an attractive current
 
                                       27
<PAGE>
return. Defined International Bond Funds, invested in bonds payable in foreign
currencies, offer a potential to profit from changes in currency values and
possibly from interest rates higher than paid on comparable U.S. bonds, but
investors incur a higher risk for these potentially greater returns.
Historically, stocks have offered growth of capital, and thus some protection
against inflation, over the long term. Defined Equity Income Funds offer
participation in the stock market, providing current income as well as the
possibility of capital appreciation. The S&P Index Trusts offer a convenient and
inexpensive way to participate in broad market movements. Concept Series seek to
capitalize on selected anticipated economic, political or business trends.
Utility Stock Series, consisting of stocks of issuers with established
reputations for regular cash dividends, seek to benefit from dividend increases.
Select Ten Portfolios seek total return by investing for one year in the ten
highest yielding stocks on a designated stock index.

DESCRIPTION OF RATINGS (AS DESCRIBED BY THE RATING COMPANIES THEMSELVES)
 
STANDARD & POOR'S RATINGS GROUP, A DIVISION OF MCGRAW-HILL, INC.
 
     AAA--Debt rated AAA has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.
 
     AA--Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.
 
     A--Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.
 
     BBB--Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.
 
     BB, B, CCC, CC--Debt rated BB, B, CCC and CC is regarded, on balance, as
predominately speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and CC the highest degree of speculation. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions.
 
     The ratings may be modified by the addition of a plus or minus sign to show
relative standing within the major rating categories.
 
     A provisional rating, indicated by 'p' following a rating, assumes the
successful completion of the project being financed by the issuance of the debt
being rated and indicates that payment of debt service requirements is largely
or entirely dependent upon the successful and timely completion of the project.
This rating, however, while addressing credit quality subsequent to completion
of the project, makes no comment on the likelihood of, or the risk of default
upon failure of, such completion.
 
     NR--Indicates that no rating has been requested, that there is insufficient
information on which to base a rating or that Standard & Poor's does not rate a
particular type of obligation as a matter of policy.
 
MOODY'S INVESTORS SERVICE, INC.
 
     Aaa--Bonds which are rated Aaa are judged to be the best quality. They
carry the smallest degree of investment risk and are generally referred to as
'gilt edge'. Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
     Aa--Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.
 
     A--Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations. Factors giving security
to principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future.
 
     Baa--Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
 
     Ba--Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate, and thereby not well
 
                                      a-1
<PAGE>
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
     B--Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
     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 give investors a more precise indication of relative debt quality
in each of the historically defined categories.
 
     Conditional ratings, indicated by 'Con.', are sometimes given when the
security for the bond depends upon the completion of some act or the fulfillment
of some condition. Such bonds are given a conditional rating that denotes their
probable credit stature upon completion of that act or fulfillment of that
condition.
 
     NR--Should no rating be assigned, the reason may be one of the following:
(a) an application for rating was not received or accepted; (b) the issue or
issuer belongs to a group of securities that are not rated as a matter of
policy; (c) there is a lack of essential data pertaining to the issue or issuer
or (d) the issue was privately placed, in which case the rating is not published
in Moody's publications.
 
FITCH INVESTORS SERVICE, INC.
 
     AAA--These bonds are considered to be investment grade and of the highest
quality. The obligor has an extraordinary ability to pay interest and repay
principal, which is unlikely to be affected by reasonably foreseeable events.
 
     AA--These bonds are considered to be investment grade and of high quality.
The obligor's ability to pay interest and repay principal, while very strong, is
somewhat less than for AAA rated securities or more subject to possible change
over the term of the issue.
 
     A--These bonds are considered to be investment grade and of good quality.
The obligor's ability to pay interest and repay principal is considered to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.
 
     BBB--These bonds are considered to be investment grade and of satisfactory
quality. The obligor's ability to pay interest and repay principal is considered
to be adequate. Adverse changes in economic conditions and circumstances,
however are more likely to weaken this ability than bonds with higher ratings.
 
     A '+' or a '-' sign after a rating symbol indicates relative standing in
its rating.
 
DUFF & PHELPS CREDIT RATING CO.
 
     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 condtions.
 
     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.

THE FLORIDA TRUST
 
     The Portfolio of the Florida Trust contains different issues of long-term
debt obligations issued by or on behalf of the State of Florida (the 'State')
and counties, municipalities and other political subdivisions and other public
authorities thereof or by the Government of Puerto Rico or the Government of
Guam or by their respective authorities, all rated in the category A or better
by at least one national rating organization (see Investment Summary).
Investment in the Florida Trust should be made with an understanding that the
value of the underlying Portfolio may decline with increases in interest rates.
 
     RISK FACTORS--The State Economy.  In 1980 Florida ranked seventh among the
fifty states with a population of 9.7 million people. The State has grown
dramatically since then and, as of April 1, 1993, ranked fourth with an
estimated population of 13.6 million, an increase of approximately 44.7% since
1980. Since the beginning of the eighties, Florida has surpassed Ohio, Illinois
and Pennsylvania in total population. Florida's attraction, as both a growth and
retirement state, has kept net migration fairly steady with an average of
292,988 new residents each year, from 1983 through 1993. Since 1983 the prime
working age population (18-44) has grown at an average annual rate of 2.6%. The
share of Florida's total working age population (18-59) to total State
population is approximately 54%. Non-farm employment has grown by approximately
64.4% since 1980. The service sector is Florida's largest employment sector,
presently accounting for 32.1% of total non-farm employment. Manufacturing jobs
in Florida are concentrated in the area of high-tech and value-added sectors,
such as electrical and electronic equipment, as well as printing and publishing.
Job gains in Florida's manufacturing sector have exceeded national averages
increasing by 11.7% between 1980 and 1993. Foreign Trade has contributed
significantly to Florida's employment growth. Florida's dependence on highly
cyclical construction and construction related manufacturing has declined. Total
contract construction employment as a share of total non-farm employment has
fallen from 10% in 1973, to 7% in 1980 to 5% in 1993. Although the job creation
rate for the State of Florida since 1980 is over two times the rate for the
nation as a whole, since 1989 the unemployment rate for the State has risen
faster than the national average. The average rate of unemployment for Florida
since 1980 is 6.5%, while the national average is 7.1%. Because Florida has a
proportionately greater retirement age population, property income (dividends,
interest and rent) and transfer payments (Social Security and pension benefits)
are a relatively more important source of income. In 1993, Florida employment
income represented 62% of total personal income while nationally, employment
income represented 72% of total personal income.
 
     The ability of the State and its local units of government to satisfy the
Debt Obligations may be affected by numerous factors which impact on the
economic vitality of the State in general and the particular region of the State
in which the issuer of the Debt Obligation is located. South Florida is
particularly susceptible to international trade and currency imbalances and to
economic dislocations in Central and South America, due to its geographical
location and its involvement with foreign trade, tourism and investment capital.
The central and northern portions of the State are impacted by problems in the
agricultural sector, particularly with regard to the citrus and sugar
industries. Short-term adverse economic conditions may be created in these
areas, and in the State as a whole, due to crop failures, severe weather
conditions or other agriculture-related problems. The State economy also has
historically been somewhat dependent on the tourism and construction industries
and is sensitive to trends in those sectors.
 
     The State Budget.  The State operates under a biennial budget which is
formulated in even numbered years and presented for approval to the Legislature
in odd numbered years. A supplemental budget request process is utilized in the
even numbered years for refining and modifying the primary budget. Under the
State Constitution and applicable statutes, the State budget as a whole, and
each separate fund within the State budget, must be kept in balance from
currently available revenues during each State fiscal year. (The State's fiscal
year runs from July 1 through June 30). The Governor and the Comptroller of the
State are charged with the responsibility of ensuring that sufficient revenues
are collected to meet appropriations and that no deficit occurs in any State
fund.
 
     The financial operations of the State covering all receipts and
expenditures are maintained through the use of three types of funds: the General
Revenue Fund, Trust Funds and Working Capital Fund. The majority of the State's
tax revenues are deposited in the General Revenue Fund and moneys in the General
Revenue Fund are expended pursuant to appropriations acts. In fiscal year
1992-93, expenditures for education, health and welfare and public safety
represented approximately 49%, 30% and 11%, respectively, of expenditures from
the General
 
                                      d-1
<PAGE>
Revenue Fund. The Trust Funds consist of moneys received by the State which
under law or trust agreement are segregated for a purpose authorized by law.
Revenues in the General Revenue Fund which are in excess of the amount needed to
meet appropriations may be transferred to the Working Capital Fund.
 
     State Revenues.  Estimated General Revenue and Working Capital Fund
revenues of $13,582.7 million for 1993-94 (excluding Hurricane Andrew related
revenues and expenses) represent an increase of 8.4% over revenues for 1992-93.
This amount reflects a transfer of $190 million, out of an estimated $220
million in non-recurring revenue due to Hurricane Andrew, to a hurricane relief
trust fund. Estimated Revenue for 1994-95 of $14,573.8 million (excluding
Hurricane Andrew impacts) represent an increase of 7.3% over 1993-1994. This
amount reflects a transfer of $159 million in non-recurring revenue due to
Hurricane Andrew, to a hurricane relief trust fund.
 
     In fiscal year 1992-1993, the State derived approximately 62% of its total
direct revenues for deposit in the General Revenue Fund, Trust Funds and Working
Capital Fund from State taxes. Federal funds and other special revenues
accounted for the remaining revenues. The greatest single source of tax receipts
in the State is the 6% sales and use tax. For the fiscal year ended June 30,
1993, receipts from the sales and use tax totalled $9,426 million, an increase
of approximately 12.5% over fiscal year 1991-92. This amount includes
non-recurring increases attributable to the rebuilding and reconstruction
following the hurricane. The second largest source of State tax receipts is the
tax on motor fuels including the tax receipts distributed to local governments.
Receipts from the taxes on motor fuels are almost entirely dedicated to trust
funds for specific purposes or transferred to local governments and are not
included in the General Revenue Fund. For the fiscal year ended June 30, 1992,
collections of this tax totalled $1,475.5 million.
 
     The State currently does not impose a personal income tax. However, the
State does impose a corporate income tax on the net income of corporations,
organizations, associations and other artificial entities for the privilege of
conducting business, deriving income or existing within the State. For the
fiscal year ended June 30, 1993, receipts from the corporate income tax totalled
$846.6 million, an increase of approximately 5.6% from fiscal year 1991-92. The
Documentary Stamp Tax collections totalled $639 million during fiscal year
1992-93, or approximately 27% over fiscal year 1991-92. The Alcoholic Beverage
Tax, an excise tax on beer, wine and liquor totalled $442.2 million in 1992-93,
an increase of 1.6% from fiscal year 1991-92. The Florida lottery produced sales
of $2.13 billion of which $810.4 million was used for education in fiscal year
1992-93.
 
     While the State does not levy ad valorem taxes on real property or tangible
personal property, counties, municipalities and school districts are authorized
by law, and special districts may be authorized by law, to levy ad valorem
taxes. Under the State Constitution, ad valorem taxes may not be levied by
counties, municipalities, school districts and water management districts in
excess of the following respective millages upon the assessed value of real
estate and tangible personal property; for all county purposes, ten mills; for
all municipal purposes, ten mills; for all school purposes, ten mills; and for
water management purposes, either 0.05 mill or 1.0 mill, depending upon
geographic location. These millage limitations do not apply to taxes levied for
payment of bonds and taxes levied for periods not longer than two years when
authorized by a vote of the electors. (Note: one mill equals one-tenth of one
cent).
 
     The State Constitution and statutes provide for the exemption of homesteads
from certain taxes. The homestead exemption is an exemption from all taxation,
except for assessments for special benefits, up to a specific amount of the
assessed valuation of the homestead. This exemption is available to every person
who has the legal or equitable title to real estate and maintains thereon his or
her permanent home. All permanent residents of the State are currently entitled
to a $25,000 homestead exemption from levies by all taxing authorities, however,
such exemption is subject to change upon voter approval.
 
     On November 3, 1992, the voters of the State of Florida passed an amendment
to the Florida Constitution establishing a limitation on the annual increase in
assessed valuation of homestead property commencing January 1, 1994, of the
lesser of 3% or the increase in the Consumer Price Index during the relevant
year, except in the event of a sale thereof during such year, and except as to
improvements thereto during such year. The amendment did not alter any of the
millage rates described above.
 
     Since municipalities, counties, school districts and other special purpose
units of local governments with power to issue general obligation bonds have
authority to increase the millage levy for voter approved general obligation
debt to the amount necessary to satisfy the related debt service requirements,
the amendment is not expected to adversely affect the ability of these entities
to pay the principal of or interest on such general obligation bonds. However,
in periods of high inflation, those local government units whose operating
millage
 
                                      d-2
<PAGE>
levies are approaching the constitutional cap and whose tax base consists
largely of residential real estate, may, as a result of the above-described
amendment, need to place greater reliance on non-ad valorem revenue sources to
meet their operating budget needs.
 
     A joint resolution to amend the State Constitution has been adopted by the
Florida Legislature. The amendment, if approved by the voters of the state at
the November 1994 general election, would limit the amount of taxes, fees,
licenses and charges imposed by the Legislature and collected during any fiscal
year to the amount of revenues allowed for the prior fiscal year, plus an
adjustment for growth. Growth is defined as the amount equal to the average
annual rate of growth in Florida personal income over the most recent twenty
quarters times the state revenues allowed for the prior fiscal year. The
revenues allowed for any fiscal year could be increased by a two-thirds vote of
the Legislature, The limit would be effective starting with fiscal year 1995-
1996. Any excess revenues generated would be put in the budget stabilization
fund until it is fully funded and then refunded to taxpayers. Included among the
categories of revenues which are exempt from the proposed revenue limitation,
however, are revenues pledged to state bonds.
 
     State General Obligation Bonds and State Revenue Bonds.  The State
Constitution does not permit the State to issue debt obligations to fund
governmental operations. Generally, the State Constitution authorizes State
bonds pledging the full faith and credit of the State only to finance or
refinance the cost of State fixed capital outlay projects, upon approval by a
vote of the electors, and provided that the total outstanding principal amount
of such bonds does not exceed 50% of the total tax revenues of the State for the
two preceding fiscal years. Revenue bonds may be issued by the State or its
agencies without a vote of the electors only to finance or refinance the cost of
State fixed capital outlay projects which are payable solely from funds derived
directly from sources other than State tax revenues.
 
     Exceptions to the general provisions regarding the full faith and credit
pledge of the State are contained in specific provisions of the State
Constitution which authorize the pledge of the full faith and credit of the
State, without electorate approval, but subject to specific coverage
requirements, for: certain road projects, county education projects, State
higher education projects, State system of Public Education and construction of
air and water pollution control and abatement facilities, solid waste disposal
facilities and certain other water facilities.
 
     Local Bonds.  The State Constitution provides that counties, school
districts, municipalities, special districts and local governmental bodies with
taxing powers may issue debt obligations payable from ad valorem taxation and
maturing more than 12 months after issuance, only (i) to finance or refinance
capital projects authorized by law, provided that electorate approval is
obtained; or (ii) to refund outstanding debt obligations and interest and
redemption premium thereon at a lower net average interest cost rate.
 
     Counties, municipalities and special districts are authorized to issue
revenue bonds to finance a variety of self-liquidating projects pursuant to the
laws of the State, such revenue bonds to be secured by and payable from the
rates, fees, tolls, rentals and other charges for the services and facilities
furnished by the financed projects. Under State law, counties and municipalities
are permitted to issue bonds payable from special tax sources for a variety of
purposes, and municipalities and special districts may issue special assessment
bonds.
 
     Bond Ratings.  General obligation bonds of the State are currently rated Aa
by Moody's and AA by Standard & Poor's.
 
     Litigation.  Due to its size and its broad range of activities, the State
(and its officers and employees) are involved in numerous routine lawsuits. The
managers of the departments of the State involved in such routine lawsuits
believed that the results of such pending litigation would not materially affect
the State's financial position. In addition to the routine litigation pending
against the State, its officers and employees, the following lawsuits and claims
are also pending:
 
        A. In a suit, plaintiff has sought title to Hugh Taylor Birch State
     Recreation Area by virtue of a reverter clause in the deed from Hugh Taylor
     Birch to the State. A final judgment at trial was entered in favor of the
     State. The case has been appealed to the Fourth District Court of Appeal.
     The Department of Natural Resources anticipates the area will remain in
     State lands; however, in the event the court should rule in favor of the
     plaintiff, the State is subject to a loss of real property valued at
     approximately $400 million.
 
        B. In a suit, the Florida Supreme Court prospectively invalidated a tax
     preference methodology under former Sections 554.06 and 565.12 of the
     Florida Statutes (1985). This ruling was appealed to the United States
     Supreme Court which reversed the State Supreme Court and remanded the
     matter back to the State court. The Supreme Court's opinion suggested that
     one of the State's options for correcting the constitutional
 
                                      d-3
<PAGE>
     problems would be to assess and collect back taxes at the higher rates
     applicable to those who were ineligible for the tax preference from all
     taxpayers who had benefitted from the tax preference during the contested
     tax period. The State chose to seek a recovery of taxes from those who
     benefitted from the tax preference by requiring them to pay taxes at the
     higher rate that applied to out-of-state manufacturers and distributors.
     The Florida Supreme Court remanded the matter to the Circuit Court for the
     2nd Judicial Circuit to hear arguments on the method chosen by the State to
     provide a clear and certain remedy. The trial court's decision against the
     State is on appeal at the First District Court of Appeal. With the
     exception of two parties, all parties have settled their claims with the
     State. Should an unfavorable outcome result in this case, approximately $33
     million may be refunded.
 
        C. A class action suit brought against the Department of Corrections,
     alleging race discrimination in hiring and employment practices, originally
     went to trial in 1982 with the Department prevailing on all claims except a
     partial summary judgment to a plaintiff sub-class claiming a discriminatory
     impact on hiring caused by an examination requirement. Jurisdictional
     aspects of the testing issue were appealed to the Eleventh Circuit Court of
     Appeals which vacated the trial court's order and was upheld by the United
     States Supreme Court. The district court consolidated three successor
     lawsuits with this case and entered a final judgment in favor of the State.
     The judgment, however, has been appealed to the Eleventh Circuit Court of
     Appeals. Should the department fail in future appeals, the liability of the
     State for back pay and other monetary relief could exceed $40 million.
 
        D. Complaints were filed in the Second Judicial Circuit seeking a
     declaration that Sections 624.509, 624.512 and 624.514, F.S. (1988) violate
     various U.S. and Florida Constitutional provisions. Relief was sought in
     the form of a tax refund. The Florida Supreme Court reversed the trial
     court in favor of the State. Plaintiffs have petitioned for certiorari with
     the United States Supreme Court. The State has settled all outstanding
     litigation in this area. Similar issues had been raised in the following
     cases which were part of the settlement: Ford Motor Company v. Bill Gunter,
     Case No. 86-3714, 2nd Judicial Circuit, and General Motors Corporation v.
     Tom Gallagher, Case Nos. 90-2045 and 88-2925, 2nd Judicial Circuit, where
     the plaintiffs are challenging Section 634.131, F.S., which imposes taxes
     on the premiums received for certain motor vehicle service agreements.
     Current estimates indicate that the State's potential refund exposure under
     the remaining refund application yet to be denied is approximately $150
     million. However, the State hopes that refund exposure will be reduced as
     these refund requests begin to be denied based upon the Florida Supreme
     Court decision in the instant case.
 
        E. In two cases, plaintiffs have sought approximately $25 million in
     intangible tax refunds based partly upon claims that Florida's intangible
     tax statutes are unconstitutional.
 
        F. A lawsuit was filed against the Department of Health and
     Rehabilitative Services (DHRS) and the Comptroller of the State of Florida
     involving a number of issues arising out of the implementation of a DHRS
     computer system and seeking declaratory relief and money damages. The
     estimated potential liability to the State is in excess of $40 million.
 
        G. Plaintiffs in a case have sought a declaration that statutory
     assessments on certain hospital net revenues are invalid, unconstitutional,
     and unenforceable and request temporary and permanent injunctive relief be
     granted prohibiting the enforcement or collection of the assessment and
     that all monies paid to the State by the plaintiffs and the class members
     within the four years preceding the filing of the action be reimbursed by
     the defendants with interest. An unfavorable outcome to this case could
     result in the possibility of refunds exceeding $50 million. This case was
     voluntarily dismissed but may be refiled.
 
        H. In an inverse condemnation suit claiming that the actions of the
     State constitute a taking of certain leases for which compensation is due,
     the Circuit judge granted the State's motion for summary judgment finding
     that the State had not deprived plaintiff of any royalty rights they might
     have. Plaintiff has appealed. Additionally, plaintiff's request for a
     drilling permit was rejected after administrative proceedings before the
     Department of Environmental Protection. Plaintiff is expected to challenge
     the decision.
 
        I. In an inverse condemnation suit alleging the regulatory taking of
     property without compensation in the Green Swamp Area of Critical State
     Concern, discovery is concluding and a motion for a summary judgment will
     likely be made. If the judgment should be for the plaintiff, condemnation
     procedures would be instituted with costs of $30 million, plus interest
     from 1975.
 
        J. In 1990, the Florida Legislature passed an act imposing a $295 impact
     fee on cars purchased or titled in other states that are then registered in
     the State by persons having or establishing permanent residency in
 
                                      d-4
<PAGE>
     the State. Two separate groups filed suit challenging the fee. The circuit
     court consolidated the various cases and entered final summary judgment
     finding the fee unconstitutional under the Commerce Clause of the United
     States Constitution and ordered an immediate refund to all persons having
     paid the fee since the statute came into existence. The State noticed an
     appeal of the circuit court ruling which entitled the State to a stay of
     the effectiveness of such ruling, thus, the fee continued to be collected
     during the period of the pending appeal. On September 29, 1994, the Supreme
     Court of Florida reaffirmed the circuit court's decision by concluding that
     the statute results in discrimination against out of state economic
     interests in contravention of the Commerce Clause and that the proper
     remedy for such violation is a full refund to all persons who have paid the
     illegal fee. The State's refund exposure may be in excess of $100 million.
 
        K. Santa Rosa County has filed a complaint for declaratory relief
     against the State requesting the Circuit Court to: (1) find that Section
     206.60(2)(a), F.S., does not allow the Department to deduct administrative
     expenses unrelated to the collection, administration, and distribution of
     the county gas tax; and (2) order the department to pay Santa Rosa County
     all moneys shown to have been unlawfully deducted from the motor fuel tax
     revenues plus interest. Santa Rosa County obtained a prospective
     injunction, but was denied the refund it sought. There has been no appeal
     by either party. The Legislature changed the statute in accordance with the
     Court's decision.
 
        L. Lee Memorial Hospital has contested the calculation of its
     disproportionate share payment for the 1992-93 State fiscal year. An
     unfavorable outcome to this case could result in a possible settlement of
     $20 to $30 million.
 
        M. A lawsuit has challenged the freezing of nursing home reimbursement
     rates for the period January 1, 1990 through July 1, 1990. The First
     District Court of Appeal ruled against the Agency for Health Care
     Administration (AHCA). The AHCA has petitioned the Florida Supreme Court
     for review of this declaration. An unfavorable outcome to this case could
     result in a potential liability of $40 million.
 
     Summary.  Many factors including national, economic, social and
environmental policies and conditions, most of which are not within the control
of the State or its local units of government, could affect or could have an
adverse impact on the financial condition of the State. Additionally, the
limitations placed by the State Constitution on the State and its local units of
government with respect to income taxation, ad valorem taxation, bond
indebtedness and other matters discussed above, as well as other applicable
statutory limitations, may constrain the revenue-generating capacity of the
State and its local units of government and, therefore, the ability of the
issuers of the Debt Obligations to satisfy their obligations thereunder.

     FLORIDA TAXES
 
     In the opinion of Greenberg, Traurig, Hoffman, Lipoff, Rosen & Quentel,
P.A., Miami, Florida, special counsel on Florida tax matters, under existing
Florida law:
 
        1.  The Florida Trust will not be subject to income, franchise or other
     taxes of a similar nature imposed by the State of Florida or its
     subdivisions, agencies or instrumentalities.
 
        2.  Because Florida does not impose a personal income tax, non-corporate
     Holders of Units of the Florida Trust will not be subject to any Florida
     income taxes with respect to (i) amounts received by the Florida Trust on
     the Debt Obligations it holds; (ii) amounts which are distributed by the
     Florida Trust to non-corporate Holders of Units of the Florida Trust; or
     (iii) any gain realized on the sale or redemption of
 
                                      d-5
<PAGE>
     Debt Obligations by the Florida Trust or of a Unit of the Florida Trust by
     a non-corporate Holder. However, corporations as defined in Chapter 220,
     Florida Statutes (1991), which are otherwise subject to Florida income
     taxation will be subject to tax on their respective share of any income and
     gain realized by the Florida Trust and on any gain realized by a corporate
     Holder on the sale or redemption of Units of the Florida Trust by the
     corporate Holder.
 
        3.  The Units will be subject to Florida estate taxes only if held by
     Florida residents, or if held by non-residents deemed to have business
     situs in Florida. The Florida estate tax is limited to the amount of the
     credit for state death taxes provided for in Section 2011 of the Internal
     Revenue Code of 1986, as amended.
 
        4.  Bonds issued by the State of Florida or its political subdivisions
     are exempt from Florida intangible personal property taxation under Chapter
     199, Florida Statutes (1991), as amended. Bonds issued by the Government of
     Puerto Rico or by the Government of Guam, or by their authority, are exempt
     by Federal statute from taxes such as the Florida intangible personal
     property tax. Thus, the Florida Trust will not be subject to Florida
     intangible personal property tax on any Debt Obligations in the Florida
     Trust issued by the State of Florida or its political subdivisions, by the
     Government of Puerto Rico or by its authority or by the Government of Guam
     or by its authority. In addition, the Units of the Florida Trust will not
     be subject to the Florida intangible personal property tax if the Florida
     Trust invests solely in such Florida, Puerto Rico or Guam debt obligations.
 
    
THE NEW YORK TRUST
 
     The Portfolio of the New York Trust contains different issues of debt
obligations issued by or on behalf of the State of New York (the 'State') and
counties, municipalities and other political subdivisions and other public
authorities thereof or by the Government of Puerto Rico or the Government of
Guam or by their respective authorities, all rated in the category A or better
by at least one national rating organization (see Investment Summary).
Investment in the New York Trust should be made with an understanding that the
value of the underlying Portfolio may decline with increases in interest rates.
 
     RISK FACTORS--Prospective investors should consider the financial
difficulties and pressures which the State of New York and several of its public
authorities and municipal subdivisions have undergone. The following briefly
summarizes some of these difficulties and the current financial situation, based
principally on certain official statements currently available; copies may be
obtained without charge from the issuing entity, or through the Agent for the
Sponsors upon payment of a nominal fee. While the Sponsors have not
independently verified this information, they have no reason to believe that it
is not correct in all material respects.
 
     New York State.  In recent fiscal years, there have been extended delays in
adopting the State's budget, repeated revisions of budget projections,
significant revenue shortfalls (as well as increased expenses) and year-end
borrowing to finance deficits. These developments reflect faster long-term
growth in State spending than revenues and that the State was earlier and more
severely affected by the recent economic recession than most of the rest of the
country, as well as its substantial reliance on non-recurring revenue sources.
The State's general fund incurred cash basis deficits of $775 million, $1,081
million and $575 million, respectively, for the 1990-1992 fiscal years. Measures
to deal with deteriorating financial conditions included transfers from reserve
funds, recalculating the State's pension fund obligations (subsequently ruled
illegal), hiring freezes and layoffs, reduced aid to localities, sales of State
property to State authorities, and additional borrowings (including issuance of
additional short-term tax and revenue anticipation notes payable out of
impounded revenues in the next fiscal year). The general fund realized a $671
million surplus for the fiscal year ended March 31, 1993, and a $1.54 billion
surplus is projected for the fiscal year ended March 31, 1994.
 
     Approximately $5.4 billion of State general obligation debt was outstanding
at March 31, 1994. The State's net tax-supported debt (restated to reflect
LGAC's assumption of certain obligations previously funded through issuance of
short-term debt) was $26.4 billion at March 31, 1994, up from $11.7 billion in
1984. A proposed constitutional amendment passed by the Legislature would limit
additional lease-purchase and contractual obligation financing for State
facilities, but would authorize the State without voter referendum to issue
revenue bonds within a formula-based cap, secured solely by a pledge of certain
State tax receipts. It would also restrict State debt to capital projects
included in a multi-year capital financing plan. The proposal is subject to
approval by the next legislature and by voters. Standard & Poor's reduced its
rating of the State's general obligation bonds on January 13, 1992 to A-(its
lowest rating for any state). Moody's reduced its ratings of State general
obligation bonds from A1 to A on June 6, 1990 and to Baa1, its rating of $14.2
billion of appropriation-backed debt of the State and State agencies (over
two-thirds of the total debt) on January 6, 1992.
 
                                      d-6
<PAGE>
     In May 1991 (nearly 2 months after the beginning of the 1992 fiscal year),
the State Legislature adopted a budget to close a projected $6.5 billion gap
(including repayment of $905 million of fiscal 1991 deficit notes). Measures
included $1.2 billion in new taxes and fees, $0.9 billion in non-recurring
measures and about $4.5 billion of reduced spending by State agencies (including
layoffs), reduced aid to localities and school districts, and Medicaid cost
containment measures. After the Governor vetoed $0.9 billion in spending, the
State adopted $0.7 billion in additional spending, together with various
measures including a $100 million increase in personal income taxes and $180
million of additional non-recurring measures. Due primarily to declining
revenues and escalating Medicaid and social service expenditures, $0.4 billion
of administrative actions, $531 million of year-end short-term borrowing and a
$44 million withdrawal from the Tax Stabilization Reserve Fund were required to
meet the State's cash flow needs.
 
     The State budget to close a projected $4.8 billion gap for the State's 1993
fiscal year (including repayment of the fiscal 1992 short-term borrowing)
contained a combination of $3.5 billion of spending reductions (including
measures to reduce Medicaid and social service spending, as well as further
employee layoffs, reduced aid to municipalities and schools and reduced support
for capital programs), deferral of scheduled tax reductions, and some new and
increased fees. Nonrecurring measures aggregated $1.18 billion. The City and its
Board of Education sued the Governor and various other State officials in March
1993, claiming that the State's formula for allocating aid to education
discriminated against City schools by at least $274 million in the 1993 fiscal
year.
 
     To close a projected budget gap of nearly $3 billion for the fiscal year
ended March 31, 1994, the State budget contained various measures including
deferral of scheduled income tax reductions for a fourth year, some tax
increases, $1.6 billion in spending cuts, especially for Medicaid, and further
reduction of the State's work force. The budget increased aid to schools, and
included a formula to channel more aid to districts with lower-income students
and high property tax burdens. State legislation requires deposit of receipts
from the petroleum business tax and certain other transportation-related taxes
into funds dedicated to transportation purposes. Nevertheless, $516 million of
these monies were retained in the general fund during this fiscal year. The
Division of the Budget has estimated that non-recurring income items other than
the $671 million surplus from the 1993 fiscal year aggregated $318 million. $89
million savings from bond refinancings was deposited in a contingency reserve
fund to pay litigation settlements, particularly to repay monies received under
the State's abandoned property law, which the State will be required to give up
as described below.
 
     The budget for the fiscal year that began April 1, 1994 increases spending
by 3.8% (greater than inflation for the first time in six years). Tax revenue
projections are based on assumed modest growth in the State economy. It provides
a tax credit for low income families and increases aid to education, especially
in the poorer districts. The litigation fund will be increased and then paid out
during the year. The State is reducing coverage and placing additional
restrictions on certain health care services. Over $1 billion results from
further postponement of scheduled reductions in personal income taxes and in
taxes on hospital income; another $1 billion comes from rolling over the
projected surplus from the previous fiscal year. Other non-recurring measures
would be reduced to $78 million. The State Legislature passed legislation to
implement a budget agreement more than two months after the beginning of the
year. Taxes (principally business taxes) would be reduced by $475 million in the
current fiscal year and by $1.6 billion annually after fully phased in. In
November 1993 the State's Court of Appeals ruled unconstitutional 1990
legislation which postponed employee pension contributions by the State and
localities (other than New York City). The amounts to be made up, estimated to
aggregate $4 billion (half from the State), would be repaid in increasing
amounts over 12-20 years under a plan proposed by the State Comptroller, trustee
of the State pension system, and previous contribution levels will not be
exceeded until 1999. State and other estimates are subject to uncertainties
including the effects of Federal tax legislation and economic developments.
 
     The State normally adjusts its cash basis balance by deferring until the
first quarter of the succeeding fiscal year substantial amounts of tax refunds
and other disbursements. For many years, it also paid in that quarter more than
40% of its annual assistance to local governments. Payment of these annual
deferred obligations and the State's accumulated deficit was substantially
financed by issuance of short-term tax and revenue anticipation notes shortly
after the beginning of each fiscal year. The New York Local Government
Assistance Corporation ('LGAC') was established in 1990 to issue long-term bonds
over several years, payable from a portion of the State sales tax, to fund
certain payments to local governments traditionally funded through the State's
annual seasonal borrowing. The legislation will normally limit the State's
short-term borrowing, together with net proceeds of LGAC bonds ($3.9 billion to
date), to a total of $4.7 billion. The State's last seasonal borrowing, in May
1993, was $850 million.
 
     Generally accepted accounting principles ('GAAP') for municipal entities
apply modified accrual accounting and give no effect to payment deferrals. On an
audited GAAP basis, the State's government funds group recorded
 
                                      d-7
<PAGE>
operating deficits of $1.2 billion and $1.4 billion for the 1990 and 1991 fiscal
years. For the same periods the general fund recorded deficits (net of transfers
from other funds) of $0.7 billion and $1.0 billion. Reflecting $1.6 billion,
$881 million and $875 million of payments by LGAC to local governments out of
proceeds from bond sales, the general fund realized surpluses of $1.7 billion,
$2.1 billion and $0.9 billion for the 1992, 1993 and 1994 fiscal years,
respectively, leaving an accumulated deficit of $2.551 billion.
 
     For decades, the State's economy has grown more slowly than that of the
rest of the nation as a whole. Part of the reason for this decline has been
attributed to the combined State and local tax burden, which is the second
highest in the nation (over 60% above the national average). The State's
dependence on Federal funds and sensitivity to changes in economic cycles, as
well as the high level of taxes, may continue to make it difficult to balance
State and local budgets in the future. The total employment growth rate in the
State has been below the national average since 1984. The State lost 524,000
jobs in 1990-1993. It regained approximately 100,000 jobs from early 1993
through June 1994, but continues to have higher unemployment than the national
average.
 
     New York City (the 'City').  The City is the State's major political
subdivision. In 1975, the City encountered severe financial difficulties,
including inability to refinance $6 billion of short-term debt incurred to meet
prior annual operating deficits. The City lost access to the public credit
markets for several years and depended on a variety of fiscal rescue measures
including commitments by certain institutions to postpone demands for payment, a
moratorium on note payment (later declared unconstitutional), seasonal loans
from the Federal government under emergency congressional legislation, Federal
guarantees of certain City bonds, and sales and exchanges of bonds by The
Municipal Assistance Corporation for the City of New York ('MAC') to fund the
City's debt.
 
     MAC has no taxing power and pays its obligations out of sales taxes imposed
within the City and per capita State aid to the City. The State has no legal
obligation to back the MAC bonds, although it has a 'moral obligation' to do so.
MAC is now authorized to issue bonds only for refunding outstanding issues and
up to $1.5 billion should the City fail to fund specified transit and school
capital programs. The State also established the Financial Control Board ('FCB')
to review the City's budget, four-year financial plans, borrowings and major
contracts. These were subject to FCB approval until 1986 when the City satisfied
statutory conditions for termination of such review. The FCB is required to
reimpose the review and approval process in the future if the City were to
experience certain adverse financial circumstances. The City's fiscal condition
is also monitored by a Deputy State Comptroller.
 
   
     The City projects that it is emerging from four years of economic
recession. From 1989 through 1993, the gross city product declined by 10.1% and
employment, by almost 11%, while the public assistance caseload grew by over
25%. Unemployment averaged 10.8% in 1992 and 10.1% in 1993, peaking at 13.4% in
January 1993, the highest level in 25 years. It dropped to 7.2% in September,
1994. The number of persons on welfare exceeds 1.1 million, the highest level
since 1972, and one in seven residents is currently receiving some form of
public assistance.
    
 
     While the City, as required by State law, has balanced its budgets in
accordance with GAAP since 1981, this has required exceptional measures in
recent years. The FCB has commented that City expenditures have grown faster
than revenues each year since 1986, masked in part by a large number of
non-recurring gap closing actions. To eliminate potential budget gaps of $1-$3
billion each year since 1988 the City has taken a wide variety of measures. In
addition to increased taxes and productivity increases, these have included
hiring freezes and layoffs, reductions in services, reduced pension
contributions, and a number of nonrecurring measures such as bond refundings,
transfers of surplus funds from MAC, sales of City property and tax receivables.
The FCB concluded that the City has neither the economy nor the revenues to do
everything its citizens have been accustomed to expect.
 
     The City closed a budget gap for the 1993 fiscal year (estimated at $1.2
billion) through actions including service reductions, productivity initiatives,
transfer of $0.5 billion surplus from the 1992 fiscal year and $100 million from
MAC. A November 1992 revision offset an additional $561 million in projected
expenditures through measures including a refunding to reduce current debt
service costs, reduction in the reserve and an additional $81 million of gap
closing measures. Over half of the City's actions to eliminate the gap were non-
recurring.
 
     The Financial Plan for the City's 1994 fiscal year relied on increases in
State and Federal aid, as well as the 1993 $280 million surplus and a partial
hiring freeze, to close a gap resulting primarily from labor settlements and
decline in property tax revenues. The Plan contained over $1.3 billion of
one-time revenue measures including
 
                                      d-8
<PAGE>
bond refundings, sale of various City assets and borrowing against future
property tax receipts. On July 2, 1993, the previous Mayor ordered spending
reductions of about $130 million for the 1994 fiscal year and $400 million for
the 1995 fiscal year. A new Mayor and City Comptroller assumed office in January
1994. Various fiscal monitors criticized reliance on non-recurring revenues,
with attendant increases in the gaps for future years. The new Mayor initiated a
program to reduce non-personnel costs by up to $150 million. The FCB reported
that although a $98 million surplus was projected for the year (the surplus was
actually $81 million ), a $312 million shortfall in budgeted revenues and $904
million of unanticipated expenses (including an unbudgeted increase of over
3,300 employees and a record level of overtime), net of certain increased
revenues and other savings, resulted in depleting prior years' surpluses by $326
million. The new City Comptroller critized retention of a proposal to sell
delinquent property tax receivables.
 
     The City's Financial Plan for the current fiscal year (that began July 1,
1994) proposes both to eliminate a projected $2.3 billion budget gap and to
stabilize overall spending while beginning to reduce some business and other
taxes. It calls for a reduction of 15,000 in the City work-force by June 1995
unless equivalent productivity savings are negotiated with unions; with the aid
of $200 million from MAC, the City induced 6,100 workers to accept voluntary
severance, and union leaders accepted transfer of remaining employees between
agencies. The Plan projects about $560 million of increased State and Federal
aid, some of which has not yet been approved. Non-recurring measures include
$225 million from refinancing outstanding bonds (which the FCB estimates will
cancel almost 10% of the debt service savings anticipated from the recent
capital plan reduction), extension of the repayment schedule of a debt to City
pension funds and revision of actuarial assumptions to reduce contribution
levels, and sale of a City-owned hotel. A proposal for City employees to bear
$200 million of their health care costs must be negotiated with the unions,
which have announced their opposition. In early July, the private members of the
FCB issued a statement concluding that further budget cuts will be required to
balance the current year's budget. Since the Financial Plan was adopted, the
City has experienced lower than anticipated tax collections, higher than
budgeted costs (particularly overtime) and increased likelihood that various
revenue measures including certain anticipated Federal and State aid, and sale
of certain city assets will not occur, at least during the current fiscal year.
Although formal revision of the Financial Plan will not be submitted until
October 1994, in July 1994 the Mayor ordered expenditure reductions of $250
million during the next six months and a contingency plan for another $200
million. In late September, the Mayor's office projected that further measures
will be needed to close an additional budget gap of $800 million to $1 billion
for the current fiscal year. It has been reported that the Mayor is seeking
substantial further reductions in the City's workforce and is considering how an
expanded severance program could be funded. Several Covered Organizations have
stated that any further expenditure reductions are likely to require significant
reductions in services.
 
     The Mayor is exploring the possibility of privatizing some of the City's
services. The City Council passed legislation which would authorize the Council
to hold hearings on any significant privatization and would require submission
of a cost-benefit analysis. The Mayor has also been seeking greater control over
spending by independent authorities and agencies such as the Board of Education,
the Health and Hospital Corporation and the TA. The Mayor's efforts to reduce
expenditures by the Board of Education, including appointment of another fiscal
monitor, reduction in City funding of capital projects and rejection of a
tentative labor contract, have strained relations with the Schools Chancellor at
a time of rising enrollments. In March 1994 the Mayor reduced cash incentives to
landlords renting apartments to the homeless, and it has been reported that he
is considering proposals including eliminating City financing of a program that
creates housing for single homeless people, requiring able-bodied welfare
recipients to render community service, charging shelter occupants who refuse
offers of treatment or training a modest rent for use of the shelter, and
replacing some of the subsidies to day care centers with a voucher system. The
Mayor is considering a plan to fingerprint welfare recipients in the City; this
could be subject to legal challenge. Budget gaps of $1.5 billion, $2.0 billion
and $2.4 billion have been projected for the 1996 through 1998 fiscal years,
respectively. The State Comptroller suggested the gaps could exceed these
estimates by about $1.2 billion annually, while the FCB estimated risks of over
$2 billion, $3 billion and $3 billion respectively. Even after recent capital
plan reductions, debt service is expected to consume 18.4% of tax revenue by the
1998 fiscal year. The FCB commented that, in spite of the Mayor's measures,
spending (principally debt service, Medicaid costs and health and pension
benefits) would continue to increase faster than revenues.
 
     A major uncertainty is the City's labor costs, which represent about 50% of
its total expenditures. The City's workforce grew by 34% during the 1980s. A
January 1993 agreement covering approximately 44% of City workers followed
negotiations lasting nearly two years. Workers will receive wage and benefit
raises totalling 8.25% over 39 months ending March 1995. An agreement announced
in August 1993 provides wage increases for City teachers averaging 9% over the
48 1/2 months ending October 1995. The City is seeking to negotiate
 
                                      d-9
<PAGE>
workforce productivity initiatives, savings from which would be shared with the
workers involved. Under a tentative contract reached in September 1994, while
sanitation workers would receive an overall increase of 8.25% in wages and
benefits over 39 months, routes would be lengthened by an average of 20%. The
Financial Plan assumes no further wage increases after the 1995 fiscal year.
Also, costs of some previous wage increases were offset by reduced contributions
to pension funds; if fund performance is less than the 9% annual earnings
projected (as is expected in the current fiscal year), the City could incur
increased expenses in future years. Pension fund earnings assumptions are
currently being reviewed, and future City pension contributions could be
increased by a substantial amount.
 
     Budget balance may also be adversely affected by the effect of the economy
on economically sensitive taxes. Reflecting the downturn in real estate prices
and increasing defaults, estimates of property tax revenues have been reduced.
Other uncertainties include additional expenditures to combat deterioration in
the City's infrastructure (such as bridges, schools and water supply), costs of
developing alternatives to ocean dumping of sewage sludge (which the City
expects to defray through increased water and sewer charges), cost of the AIDS
epidemic, problems of drug addiction and homelessness and the impact of any
future State assistance payment reductions. For example, the City may be ordered
to spend up to $8 billion to construct water filtration facilities if it is not
successful in implementing measures to prevent pollution of its watershed
upstate. In late September the City was held in contempt and fined for failure
to provide shelter on a timely basis for homeless families. Several similar
decisions had been rendered against the previous administration. Elimination of
any additional budget gaps will require various actions, including by the State,
a number of which are beyond the City's control. Staten Island voters in 1993
approved a proposed charter under which Staten Island would secede from the
City. Secession will require enabling legislation by the State Legislature; it
would also be subject to legal challenge by the City. The effects of secession
on the City cannot be determined at this time, but questions include
responsibility for outstanding debt, a diminished tax base, and continued use of
the Fresh Kills landfill, the City's only remaining garbage dump. A similar
measure with respect to Queens was approved by the New York State Senate.
 
     In December 1993, a report commissioned by the City was released,
describing the nature of the City's structural deficit. It projects that the
City will need to identify and implement $5 billion in annual gap closing
measures by 1998. The report suggests a variety of possible measures for City
consideration. While the new Mayor rejected out of hand many of the proposals
such as tax increases, the State Comptroller urged him to reconsider the report.
 
     The City sold $1.4 billion, $1.8 billion and $2.2 billion of short-term
notes, respectively, during the 1993, 1994 and current fiscal years. The FCB
recently recommended development of a cash budgeting system to reduce short-term
borrowing resulting from timing imbalances. At June 30, 1994, there were
outstanding $21.7 billion of City bonds (not including City debt held by MAC),
$4.2 billion of MAC bonds and $0.8 billion of City-related public benefit
corporation indebtedness, each net of assets held for debt service. Standard &
Poor's and Moody's during the 1975-80 period either withdrew or reduced their
ratings of the City's bonds. Standard & Poor's currently rates the City's debt
A-with a negative outlook while Moody's rates City bonds Baa1. City-related debt
almost doubled since 1987, although total debt declined as a percentage of
estimated full value of real property. The City's financing program projects
long-term financing during fiscal years 1995-1998 to aggregate $17.8 billion.
The City's latest Ten Year Capital Strategy plans capital expenditures of $45.6
billion during 1994-2003 (93% to be City funded). The State Comptroller has
criticized some City bond refinancings for producing short-term savings at the
expense of greater overall costs, especially in future years. Annual debt
service is projected to increase.
 
     Other New York Localities.  In 1992, other localities had an aggregate of
approximately $15.7 billion of indebtedness outstanding. In recent years,
several experienced financial difficulties. A March 1993 report by Moody's
Investors Service concluded that the decline in ratings of most of the State's
largest cities in recent years resulted from the decline in the State's
manufacturing economy. Seventeen localities had outstanding indebtedness for
deficit financing at the close of their respective 1992 fiscal years. In
response to requests from an unprecedented 10 local government units (including
Nassau and Suffolk counties) in 1992 for legislative authority to issue bonds to
fund deficits, the State Comptroller recommended legislation to establish
earlier State oversight of municipal deficits. In September, 1992, the previous
Comptroller proposed regulations which would prohibit use of certificates of
participation by municipalities for deficit financing or refundings. Some local
leaders complained that the deficits resulted from reduced State aid accompanied
by increases in State-mandated expenditures. Any reductions in State aid to
localities may cause additional localities to experience difficulty in achieving
balanced budgets. If special local assistance were needed from the State in the
future, this could adversely affect the State's as well as the localities'
financial condition. Most localities depend on substantial
 
                                      d-10
<PAGE>
annual State appropriations. Legal actions by utilities to reduce the valuation
of their municipal franchises, if successful, could result in localities
becoming liable for substantial tax refunds.
 
     State Public Authorities.  In 1975, after the Urban Development Corporation
('UDC'), with $1 billion of outstanding debt, defaulted on certain short-term
notes, it and several other State authorities became unable to market their
securities. Since 1975 the State has provided substantial direct and indirect
financial assistance to UDC, the Housing Finance Agency ('HFA'), the
Environmental Facilities Corporation and other authorities. Practical and legal
limitations on these agencies' ability to pass on rising costs through rents and
fees could require further State appropriations. 18 State authorities had an
aggregate of $63.5 billion of debt outstanding at September 30, 1993. At March
31, 1994, approximately $0.4 billion of State public authority obligations was
State-guaranteed, $7.3 billion was moral obligation debt (including $4.8 billion
of MAC debt) and $16.6 billion was financed under lease-purchase or contractual
obligation financing arrangements with the State. Various authorities continue
to depend on State appropriations or special legislation to meet their budgets.
 
     The Metropolitan Transportation Authority ('MTA'), which oversees operation
of the City's subway and bus system by the City Transit Authority (the 'TA') and
operates certain commuter rail lines, has required substantial State and City
subsidies, as well as assistance from several special State taxes. Projections
of TA revenues were reduced due to declining ridership, increasing fare evasion,
reductions in State and City aid and declining revenues from City real estate
taxes. It was reported in December 1993 that a twenty-year trend in declining
bus ridership is expected to continue. While the MTA used bond refinancings and
other measures to avert a commuter rail line fare increase in 1992, measures
including a fare increase eliminated the TA's 1992 budget gap. Measures to
balance the TA's 1993 budget included increased funding by the City, increased
bridge and tunnel tolls and allocation of part of the revenues from the
Petroleum Business Tax. Cash basis gaps of $300-600 million are projected for
each of the 1995 through 1998 years. Measures proposed to close these gaps
include various additional State aid and possible fare increases. However, it
was projected in May 1994 that the effect of the improving economy on
transportation-dedicated taxes and on ridership, as well as implementation of
cost savings, would permit deferral of fare increases until at least July 1995.
A tentative agreement with TA workers reached in July 1994, which provides 10.4%
wage increases over 39 months, would cost the MTA $337 million. The MTA Chairman
stated that this cost would be partly offset by savings from work rule changes
and that money for the settlement is available in the TA's budget. An earlier
settlement with Long Island Railroad workers is expected to cost the MTA $14
million over 26 months.
 
     The MTA's Chairman proposed a 5 year financial strategy, including a
variety of fare changes; however, even if these are approved, an estimated $700
million in additional funds will be needed from State and City financial
assistance. Substantial claims have been made against the TA and the City for
damages from a 1990 subway fire and a 1991 derailment. The MTA infrastructure,
especially in the City, needs substantial rehabilitation. In December 1993, a
$9.5 billion MTA Capital Plan was finally approved for 1992-1996, although $500
million is contingent on increased contributions from the City; the City has
until late 1994 to decide if it will make these contributions. The MTA's
Chairman has threatened to raise subway fares and borrow more if the City fails
to make up this amount. The City is seeking State and MAC approval to defer $245
million of capital contributions to the TA from the current fiscal year until
1998. It is anticipated that the MTA and the TA will continue to require
significant State and City support. Moody's reduced its rating of certain MTA
obligations to Baa on April 14, 1992.
 
     A Federal District Court ruled in February 1993 that State surcharges of up
to 24% on hospital bills paid by commercial insurance companies and health
maintenance organizations, much of which is used to subsidize care of uninsured
patients, violate Federal law; however, the Court permitted continuance of the
system pending appeal of the ruling.
 
     Litigation.   The State and the City are defendants in numerous legal
proceedings, including challenges to the constitutionality and effectiveness of
various welfare programs, alleged torts and breaches of contract, condemnation
proceedings and other alleged violations of laws. Adverse judgments in these
matters could require substantial financing not currently budgeted. For example,
in addition to real estate certiorari proceedings, claims in excess of $343
billion were outstanding against the City at June 30, 1993, for which it
estimated its potential future liability at $2.2 billion. Another action seeks a
judgment that, as a result of an overestimate by the State Board of Equalization
and Assessment, the City's 1992 real estate tax levy exceeded constitutional
limits. In March 1993, the U.S. Supreme Court ruled that if the last known
address of a beneficial owner of accounts held by banks and brokerage firms
cannot be ascertained, unclaimed funds therein belong to the state of the
broker's incorporation rather than where its principal office is located. New
York has obtained about $350 million of
 
                                      d-11
<PAGE>
abandoned funds that could have to be paid to other States. It has agreed to pay
Delaware $200 million over a five-year period. The case has been remanded to a
special master to determine disposition of these monies.
 
     Final adverse decisions in any of these cases could require extraordinary
appropriations at either the State or City level or both.
 
     NEW YORK TAXES
 
     In the opinion of Davis Polk & Wardwell, special counsel for the Sponsors,
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 his pro rata portion of each
     Debt Obligation when interest on the Debt Obligation is received by the
     Trust. In the opinion of bond counsel delivered on the date of issuance of
     the Debt Obligation, such interest will be exempt from New York State and
     City personal income taxes except where such interest is subject to Federal
     income taxes (see Taxes). A noncorporate Holder of Units of the Trust who
     is a New York State (and City) resident will be subject to New York State
     (and City) personal income taxes on any gain recognized when he disposes of
     all or part of his pro rata portion of a Debt Obligation. 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 such gain 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 his tax
     basis for his pro rata portion of each Debt Obligation for New York State
     (and City) income tax purposes in the same manner as for Federal income tax
     purposes. Interest income on a Holder's pro rata portion of the Debt
     Obligations is generally not excludable from income in computing New York
     State and City corporate franchise taxes.
 
THE PENNSYLVANIA TRUST
 
     The Portfolio of the Pennsylvania Trust contains different issues of debt
obligations issued by or on behalf of the State of Pennsylvania (the 'State')
and counties, municipalities and other political subdivisions and other public
authorities thereof or by the Government of Puerto Rico or the Government of
Guam or by their respective authorities, all rated in the category A or better
by at least one national rating organization (see Investment Summary).
Investment in the Pennsylvania Trust should be made with an understanding that
the value of the underlying Portfolio may decline with increases in interest
rates.
 
     RISK FACTORS--Prospective investors should consider the financial
difficulties and pressures which the Commonwealth of Pennsylvania and certain of
its municipal subdivisions have undergone. Both the Commonwealth and the City of
Philadelphia are experiencing significant revenue shortfalls. There can be no
assurance that the Commonwealth will not experience a further decline in
economic conditions or that portions of the municipal obligations contained in
the Portfolio of the Pennsylvania Trust will not be affected by such a decline.
Without intending to be complete, the following briefly summarizes some of these
difficulties and the current financial situation, as well as some of the complex
factors affecting the financial situation in the Commonwealth. It is derived
from sources that are generally available to investors and is based in part on
information obtained from various agencies in Pennsylvania. No independent
verification has been made of the following information.
 
     State Economy.  Pennsylvania has been historically identified as a heavy
industry state although that reputation has changed recently as the industrial
composition of the Commonwealth diversified when the coal, steel and railroad
industries began to decline. The major new sources of growth in Pennsylvania are
in the service sector, including trade, medical and the health services,
education and financial institutions. Pennsylvania's agricultural industries are
also an important component of the Commonwealth's economic structure, accounting
for more than $3.6 billion in crop and livestock products annually while
agribusiness and food related industries support $38 billion in economic
activity annually.
 
     Non-agricultural employment in the Commonwealth has increased steadily from
1984 to its 1992 level of 81.3 percent of the State's employment force. The
growth in employment experienced in Pennsylvania is comparable to the nationwide
growth in employment which has occurred during this period. In 1993,
manufacturing employment represented 18.4 percent of all non-agricultural
employment in the Commonwealth while the services sector accounted for 29.9
percent and the trade sector accounted for 22.4 percent.
 
                                      d-12
<PAGE>
     The Commonwealth recently experienced a slowdown in its economy. Moreover,
economic strengths and weaknesses vary in different parts of the Commonwealth.
In general, heavy industry and manufacturing have recently been facing
increasing competition from foreign producers. During 1993, the annual average
unemployment rate in Pennsylvania was 7.0 percent compared to 6.8 percent for
the United States. For August 1994 the unadjusted unemployment rate was 6.2
percent in Pennsylvania and 5.9 percent in the United States, while the
seasonally adjusted unemployment rate for the Commonwealth was 6.3 percent and
for the United States was 6.1 percent.
 
     State Budget.  The Commonwealth operates under an annual budget which is
formulated and submitted for legislative approval by the Governor each February.
The Pennsylvania Constitution requires that the Governor's budget proposal
consist of three parts: (i) a balanced operating budget setting forth proposed
expenditures and estimated revenues from all sources and, if estimated revenues
and available surplus are less than proposed expenditures, recommending specific
additional sources of revenue sufficient to pay the deficiency; (ii) a capital
budget setting forth proposed expenditures to be financed from the proceeds of
obligations of the Commonwealth or its agencies or from operating funds; and
(iii) a financial plan for not less than the succeeding five fiscal years, which
includes for each year projected operating expenditures and estimated revenues
and projected expenditures for capital projects. The General Assembly may add,
change or delete any items in the budget prepared by the Governor, but the
Governor retains veto power over the individual appropriations passed by the
legislature. The Commonwealth's fiscal year begins on July 1 and ends on June
30.
 
     All funds received by the Commonwealth are subject to appropriation in
specific amounts by the General Assembly or by executive authorization by the
Governor. Total appropriations enacted by the General Assembly may not exceed
the ensuing year's estimated revenues, plus (less) the unappropriated fund
balance (deficit) of the preceding year, except for constitutionally authorized
debt service payments. Appropriations from the principal operating funds of the
Commonwealth (the General Fund, the Motor License Fund and the State Lottery
Fund) are generally made for one fiscal year and are returned to the
unappropriated surplus of the fund if not spent or encumbered by the end of the
fiscal year. The Constitution specifies that a surplus of operating funds at the
end of a fiscal year must be appropriated for the ensuing year.
 
     Pennsylvania uses the 'Fund' method of accounting for receipts and
disbursements. For purposes of government accounting, a 'fund' is an independent
fiscal and accounting entity with a self-balancing set of accounts, recording
cash and/or other resources together with all related liabilities and equities
that are segregated for the purpose of carrying on specific activities or
attaining certain objectives in accordance with the fund's special regulations,
restrictions or limitations. In the Commonwealth, over 150 funds have been
established by legislative enactment or in certain cases by administrative
action for the purpose of recording the receipt and disbursement of moneys
received by the Commonwealth. Annual budgets are adopted each fiscal year for
the principal operating funds of the Commonwealth and several other special
revenue funds. Expenditures and encumbrances against these funds may only be
made pursuant to appropriation measures enacted by the General Assembly and
approved by the Governor. The General Fund, the Commonwealth's largest fund,
receives all tax revenues, non-tax revenues and federal grants and entitlements
that are not specified by law to be deposited elsewhere. The majority of the
Commonwealth's operating and administrative expenses are payable from the
General Fund. Debt service on all bond indebtedness of the Commonwealth, except
that issued for highway purposes or for the benefit of other special revenue
funds, is payable from the General Fund.
 
     Financial information for the principal operating funds of the Commonwealth
is maintained on a budgetary basis of accounting, which is used for the purpose
of insuring compliance with the enacted operating budget. The Commonwealth also
prepares annual financial statements in accordance with generally accepted
accounting principles ('GAAP'). Budgetary basis financial reports are based on a
modified cash basis of accounting as opposed to a modified accrual basis of
accounting prescribed by GAAP. Financial information is adjusted at fiscal
year-end to reflect appropriate accruals for financial reporting in conformity
with GAAP.
 
     Recent Financial Results.  From fiscal 1984, when the Commonwealth first
prepared its financial statements on a GAAP basis, through fiscal 1989, the
Commonwealth reported a positive unreserved-undesignated fund balance for its
government fund types (General Fund, Special Revenue Fund and Capital Projects
Fund) at the fiscal year end. Slowing economic growth during 1990, leading to a
national economic recession beginning in fiscal 1991, reduced revenue growth and
increased expenditures and contributed to negative unreserved-undesignated fund
balances at the end of the 1990 and 1991 fiscal years. The negative
unreserved-undesignated fund balance was due largely to operating deficits in
the General Fund and the State Lottery Fund during those fiscal years. Actions
taken during fiscal 1992 to bring the General Fund back into balance, including
tax increases and expenditure restraints, resulted in a $1.1 billion reduction
to the unreserved-undesignated fund deficit for
 
                                      d-13
<PAGE>
combined governmental fund types at June 30, 1993, as a result of a $420.4
million increase in the balance. These gains were produced by continued efforts
to control expenditure growth. The Combined Balance Sheet as of June 30, 1993,
showed total fund balance and other credits for the total governmental fund
types of $1,959.9 million, a $732.1 million increase from the balance at June
30, 1992. During fiscal 1993, total assets increased by $1,296.7 million to
$7,096.4 million, while liabilities increased $564.6 million to $5,136.5
million.
 
     Fiscal 1991 Financial Results. The Commonwealth experienced a $453.6
million general fund deficit as of the end of its 1991 fiscal year. The deficit
reflected higher than budgeted expenditures, below-estimate economic activity
and growth rates of economic indicators and total tax revenue shortfalls below
those assumed in the enacted budget. Rising demands on state programs caused by
the economic recession, particularly for medical assistance and cash assistance
programs, and the increased costs of special education programs and correction
facilities and programs, contributed to increased expenditures in fiscal 1991,
while tax revenues for the 1991 fiscal year were severely affected by the
economic recession. Total corporation tax receipts and sales and use tax
receipts during fiscal 1991 were, respectively, 7.3 percent and 0.9 percent
below amounts collected during fiscal 1990. Personal income tax receipts also
were affected by the recession but not to the extent of the other major General
Fund taxes, increasing only 2.0 percent over fiscal 1990 collections. A number
of actions were taken throughout the fiscal year by the Commonwealth to mitigate
the effects of the recession on budget revenues and expenditures. The
Commonwealth initiated a number of cost-saving measures, including the firing of
2,000 state employees, deferral of paychecks and reduction of funds to state
universities, which resulted in approximately $871 million cost savings.
 
     Fiscal 1992 Financial Results.  Actions taken during fiscal 1992 to bring
the General Fund budget back into balance, including tax increases and
expenditure restraints resulted in a $1.1 billion reduction for the unreserved-
undesignated fund deficit for combined governmental fund types and a return to a
positive fund balance. Total General Fund revenues for fiscal 1992 were
$14,516.8 million which is approximately 22 percent higher than fiscal 1991
revenues of $11,877.3 million due in large part to tax increases. The increased
revenues funded substantial increases in education, social services and
corrections programs. As a result of the tax increases and certain appropriation
lapses, fiscal 1992 ended with an $8.8 million surplus after having started the
year with an unappropriated general fund balance deficit of $453.6 million.
 
     Fiscal 1993 Financial Results.  Fiscal 1993 closed with revenues higher
than anticipated and expenditures approximately as projected, resulting in an
ending unappropriated balance surplus of $242.3 million. A deduction in the
personal income tax rate in July 1992 and the one-time receipt of revenues from
retroactive corporate tax increases in fiscal 1992 were responsible, in part,
for the low growth in fiscal 1993.
 
     Fiscal 1994 Financial Results.  Commonwealth revenues during the 1994
fiscal year totaled $15,210.7 million, $38.6 million above the fiscal year
estimate, and 3.9 percent over commonwealth revenues during the 1993 fiscal
year. The sales tax was an important contributor to the higher than estimated
revenues. The strength of collections from the sales tax offset the lower than
budgeted performance of the personal income tax that ended the 1994 fiscal year
$74.4 million below estimate. The shortfall in the personal income tax was
largely due to shortfalls in income not subject to withholding such as interest,
dividends and other income. Expenditures, excluding pooled financing
expenditures and net of all fiscal 1994 appropriation lapses, totaled $14,934.4
million representing a 7.2 percent increase over fiscal 1993 expenditures.
Medical assistance and prisons spending contributed to the rate of spending
growth for the 1994 fiscal year. The Commonwealth maintained an operating
balance on a budgetary basis for fiscal 1994 producing a fiscal year ending
unappropriated surplus of $335.8 million.
 
     Fiscal 1995 Budget. On June 16, 1994, the Governor signed a $15.7 billion
general fund budget, an increase of over 3.9 percent from the fiscal 1994
budget. A substantial amount of the increase is targeted for medical assistance
expenditures, reform of the state-funded public assistance program and education
subsidies to local school districts. The budget also includes tax reductions
totaling an estimated $166.4 million benefiting principally low income families
and corporations. The fiscal 1995 budget projects a $4 million fiscal year-end
unappropriated surplus.
 
     Debt Limits and Outstanding Debt.  The Constitution of Pennsylvania permits
the issuance of the following types of debt: (i) debt to surpress insurrection
or rehabilitate areas affected by disaster; (ii) electorate approved debt; (iii)
debt for capital projects subject to an aggregate debt limit of 1.75 times the
annual average tax revenues of the preceding five fiscal years; and (iv) tax
anticipation notes payable in the fiscal year of issuance.

     Under the Pennsylvania Fiscal Code, the Auditor General is required
annually to certify to the Governor and the General Assembly certain information
regarding the Commonwealth's indebtedness. According to the most recent Auditor
General certificate, the average annual tax revenues deposited in all funds in
the five fiscal years ended June 30, 1993 was $15.5 billion, and, therefore, the
net debt limitation for the 1994 fiscal year is $27.1 billion. Outstanding net
debt totalled $5.1 billion at June 30, 1994, an increase of $37.0 million from
June 30, 1993. At February 28, 1994, the amount of debt authorized by law to be
issued, but not yet incurred was $15.0 billion.
 
     Debt Ratings.  All outstanding general obligation bonds of the Commonwealth
are rated AA-by Standard & Poor's and A1 by Moody's.
 
     City of Philadelphia.  The City of Philadelphia (the 'City' or
'Philadelphia') is the largest city in the Commonwealth. Philadelphia
experienced a series of general fund deficits for fiscal years 1988 through
1992, which have culminated in the City's present serious financial
difficulties. In its 1992 Comprehensive Annual Financial Report, Philadelphia
reported a cumulative general fund deficit of $71.4 million for fiscal year
1992.
 
     In June 1991, the Governor of Pennsylvania signed into law legislation
establishing the Pennsylvania Inter-Governmental Cooperation Authority ('PICA'),
a five-member board which would oversee the fiscal affairs of the City of
Philadelphia. The legislation empowers PICA to issue notes and bonds on behalf
of Philadelphia and also authorizes Philadelphia to levy a one-percent sales tax
the proceeds of which would be used to pay off the bonds. In return for PICA's
fiscal assistance, Philadelphia was required, among other things, to establish a
five-year financial plan that includes balanced annual budgets. Under the
legislation, if Philadelphia does not comply with such requirements, PICA may
withhold bond revenues and certain state funding.
 
     At this time, the City is operating under a five-year fiscal plan approved
by PICA on April 6, 1992. Full implementation of the five-year plan was delayed
due to labor negotiations that were not completed until October 1992, three
months after the expiration of the old labor contracts. The terms of the new
labor contracts are estimated to cost approximately $144.4 million more than
what was budgeted in the original five-year plan. An amended five-year plan was
approved by PICA in May 1993. The Mayor's latest update of the five-year
financial plan was approved by PICA on May 2, 1994.
 
     On June 5, 1992, PICA sold approximately $480 million in bonds at yields
ranging from 5.25 percent to 6.88 percent. The proceeds of the bonds were used
to cover shortfalls accumulated over fiscal years 1988 through 1991, projected
deficits for fiscal years 1992 and 1993, construction projects and other capital
expenditures. In accordance with the enabling legislation, PICA was guaranteed a
percentage of the wage tax revenue expected to be collected from Philadelphia
residents to permit repayment of the bonds. In July 1993 and August 1993, PICA
issued $643.4 million and $178.7 million, respectively, of Special Tax Revenue
Bonds to refund certain general obligation bonds of the City and to fund
additional capital projects.
 
     In January 1993, Philadelphia anticipated a cumulative general fund budget
deficit of $57 million for fiscal year 1993. In response to the anticipated
deficit, the Mayor unveiled a financial plan eliminating the budget deficit for
fiscal year 1993 through significant service cuts that included a plan to
privatize certain city-provided services. Due to an upsurge in tax receipts,
cost-cutting and additional PICA borrowings, Philadelphia completed fiscal year
1993 with a balanced general fund budget. The audit findings for fiscal year
1993 show a surplus of approximately $3 million for the fiscal year ended June
30, 1993.
 
     In January 1994, the Mayor proposed a $2.3 billion city general fund budget
that included no tax increases, no significant service cuts and a series of
modest health and welfare program increases. At that time, the Mayor also
unveiled a $2.2 billion program (the 'Philadelphia Economic Stimulus Program')
designed to stimulate Philadelphia's economy and stop the loss of 1,000 jobs a
month. However, the success of the Philadelphia Economic Stimulus Program has
been predicated upon several contingencies including, among others, $250 million
in revenues from riverboat gambling over the next three years, which first must
be approved by the state legislature, and $100 million in federal 'empowerment
zone' subsidies, which Philadelphia may or may not receive. As of January 1994,
the 1994 Philadelphia general fund budget was running at a deficit of
approximately $10 million. The Mayor has predicted that the general fund will be
balanced at the end of fiscal year 1994. The fiscal 1994 budget projects no
deficit and a balanced budget for the fiscal year ended June 30, 1994.
 
     Litigation.  The Commonwealth is a party to numerous lawsuits in which an
adverse final decision could materially affect the Commonwealth's governmental
operations and consequently its ability to pay debt service on its obligations.
The Commonwealth also faces tort claims made possible by the limited waiver of
sovereign immunity effected by Act 152, approved September 28, 1978.

     PENNSYLVANIA TAXES
 
     The following summarizes the opinion of Dechert Price & Rhoads,
Philadelphia, Pennsylvania, special counsel on Pennsylvania tax matters, under
existing law:
 
        1.  The Pennsylvania Trust will be recognized as a trust and will not be
     taxable as a corporation for Pennsylvania state and local tax purposes.
 
        2.  Units of the Pennsylvania Trust are not subject to any of the
     personal property taxes presently in effect in Pennsylvania to the extent
     of that proportion of the Trust represented by Debt Obligations issued by
     the Commonwealth of Pennsylvania, its agencies and instrumentalities, or by
     any county, city, borough, town, township, school district, municipality or
     local housing or parking authority in the Commonwealth of Pennsylvania
     ('Pennsylvania Obligations'). The taxes referred to above include the
     County Personal Property Tax, the additional personal property taxes
     imposed on Pittsburgh residents by the School District of Pittsburgh and by
     the City of Pittsburgh. The City of Pittsburgh, the School District of
     Pittsburgh and Allegheny County cannot impose personal property taxes as of
     January 1, 1995. Fund Units may be taxable under the Pennsylvania
     inheritance and estate taxes.
 
        3.  The proportion of interest income representing interest income from
     Pennsylvania Obligations distributable to Holders of the Pennsylvania Trust
     is not taxable under the Pennsylvania Personal Income Tax or under the
     Corporate Net Income Tax imposed on corporations by Article IV of the
     Pennsylvania Tax Reform Code, nor will such interest be taxable under the
     Philadelphia School District Investment Income Tax imposed on Philadelphia
     resident individuals.
 
        4.  Although there is no published authority on the subject, counsel is
     of the opinion that any insurance proceeds paid in lieu of interest on
     defaulted tax-exempt debt obligations will be exempt from the Pennsylvania
     Personal Income Tax either as payment in lieu of tax-exempt interest or as
     payments of insurance proceeds which are not included in any of the classes
     of income specified as taxable under the Pennsylvania Personal Income Tax
     Law. Further, because such insurance proceeds are excluded from the Federal
     income tax base, such proceeds will not be subject to the Pennsylvania
     Corporate Net Income Tax. Proceeds from insurance policies are expressly
     excluded from the Philadelphia School District Investment Income Tax and,
     accordingly, insurance proceeds paid to replace defaulted payments under
     any Debt Obligations will not be subject to this tax.
 
        5.  The disposition by the Pennsylvania Trust of a Pennsylvania
     Obligation (whether by sale, exchange, redemption or payment at maturity)
     will not constitute a taxable event to a Holder under the Pennsylvania
     Personal Income Tax if the Pennsylvania Obligation was issued prior to
     February 1, 1994. Further, although there is no published authority on the
     subject, counsel is of the opinion that (i) a Holder of the Pennsylvania
     Trust will not have a taxable event under the Pennsylvania state and local
     income taxes referred to in the preceding paragraph upon the redemption or
     sale of his Unit to the extent that the Trust is then comprised of
     Pennsylvania Obligations issued prior to February 1, 1994 and (ii) the
     disposition by the Trust of a Pennsylvania Obligation (whether by sale,
     exchange, redemption or payment at maturity) will not constitute a taxable
     event to a Holder under the Corporate Net Income Tax or the Philadelphia
     School District Investment Income Tax if the Pennsylvania Obligation was
     issued prior to February 1, 1984. (The School District tax has no
     application to gain on the disposition of property held by the taxpayer for
     more than six months.) Gains on the sale, exchange, redemption, or payment
     at maturity of a Pennsylvania Obligation issued on or after February 1,
     1994, will be taxable under all of these taxes, as will gains on the
     redemption or sale of a unit to the extent that the Trust is comprised of
     Pennsylvania Obligations issued on or after February 1, 1994.
 
        6.  To the extent the value of Units is represented by obligations of
     the Commonwealth of Puerto Rico or obligations of the territory of Guam,
     such value will not be subject to Pennsylvania personal property taxes to
     the extent required by Federal statutes. The proportion of income received
     by Holders derived from interest on such obligations is not taxable under
     any of the Pennsylvania State and local income taxes referred to above.
     Although Federal law does not expressly exclude from taxation gain realized
     on the disposition of obligations of Puerto Rico or of Guam, because
     interest is exempt on such obligations, Pennsylvania does not tax gain from
     the disposition of such obligations under the Personal Income Tax.

Re: Municipal Investment Trust Fund, Multistate Series - 73
    Defined Asset Funds (Florida, New York and Pennsylvania Trusts)
 
Gentlemen:
 
     Pursuant to your request for a Standard & Poor's rating on the units of the
above-captioned trusts, SEC No. 33-55099, we have reviewed the information
presented to us and have assigned a 'AAA' rating to the units of the trusts and
a 'AAA' rating to the securities contained in the trusts. The ratings are direct
reflections, of the portfolios of the trusts, which will be composed solely of
securities covered by bond insurance policies that insure against default in the
payment of principal and interest on the securities so long as they remain
outstanding. Since such policies have been issued by one or more insurance
companies which have been assigned 'AAA' claims paying ability ratings by S&P,
S&P has assigned a 'AAA' rating to the units of the trusts and to the securities
contained in the trusts.
    
 
     You have permission to use the name of Standard & Poor's Corporation and
the above-assigned ratings in connection with your dissemination of information
relating to these units, provided that it is understood that the ratings are not
'market' ratings nor recommendations to buy, hold, or sell the units of the
trusts or the securities contained in the trusts. Further, it should be
understood the rating on the units does not take into account the extent to
which trust expenses or portfolio asset sales for less than the trust's purchase
price will reduce payment to the unit holders of the interest and principal
required to be paid on the portfolio assets. S&P reserves the right to advise
its own clients, subscribers, and the public of the ratings. S&P relies on the
sponsor and its counsel, accountants, and other experts for the accuracy and
completeness of the information submitted in connection with the ratings. S&P
does not independently verify the truth or accuracy of any such information.
 
     This letter evidences our consent to the use of the name of Standard &
Poor's Corporation in connection with the rating assigned to the units in the
registration statement or prospectus relating to the units or the trusts.
However, this letter should not be construed as a consent by us, within the
meaning of Section 7 of the Securities Act of 1933, to the use of the name of
Standard & Poor's Corporation in connection with the ratings assigned to the
securities contained in the trusts. You are hereby authorized to file a copy of
this letter with the Securities and Exchange Commission.

     Please be certain to send us three copies of your final prospectus as soon
as it becomes available. Should we not receive them within a reasonable time
after the closing or should they not conform to the representations made to us,
we reserve the right to withdraw the rating.
 
     We are pleased to have had the opportunity to be of service to you. If we
can be of further help, please do not hesitate to call upon us.
 
                                          Very truly yours,
 
                                          VINCENT S. ORGO
