FLORIDA INSURED PORTFOLIO--RISK/RETURN SUMMARY

1. WHAT IS THE FUND'S OBJECTIVE?
The Fund seeks interest income that is exempt from regular
federal income taxes and some state and local taxes by
investing in a fixed portfolio consisting primarily of
insured, long term municipal revenue bonds.
2. WHAT ARE MUNICIPAL REVENUE BONDS?
Municipal revenue bonds are bonds issued by states,
municipalities and public authorities to finance the cost
of buying, building or improving various projects intended
to generate revenue, such as airports, health care
facilities, housing and municipal electric, water and sewer
utilities. Generally, payments on these bonds depend solely
on the revenues generated by the projects, excise taxes or
state appropriations, and are not backed by the
government's taxing power.

3. WHAT IS THE FUND'S INVESTMENT STRATEGY?
O The Fund plans to hold to maturity 7 long-term tax-exempt
municipal bonds with an aggregate face amount of
$3,400,000.
o The Fund is a unit investment trust which means that,
unlike a mutual fund, the Portfolio is not managed.
o The bonds are rated AAA or Aaa by Standard & Poor's,
Moody's or Fitch.
o Many of the bonds can be called at a premium declining over
time to par value. Some bonds may be called earlier at par
for extraordinary reasons.
o 100% of the bonds are insured by insurance companies that
guarantee timely payments of principal and interest on the
bonds (but not Fund units or the market value of the bonds
before they mature).

The Portfolio consists of municipal bonds of the following
types:

APPROXIMATE
PORTFOLIO
PERCENTAGE

/ / Airports/Ports/Highways 15%
/ / Hospital/Health Care 28%
/ / Municipal Water/Sewer Utilities 15%
/ / Refunded Bonds 13%
/ / Municipal Electric Utilities 29%

4. WHAT ARE THE SIGNIFICANT RISKS?
YOU CAN LOSE MONEY BY INVESTING IN THE FUND. THIS CAN
HAPPEN FOR VARIOUS REASONS, INCLUDING:
o Rising interest rates, an issuer's worsening financial
condition or a drop in bond ratings can reduce the price of
your units.
o Because the Fund is concentrated in hospital/health care
and municipal electric utility bonds, adverse developments
in these sectors may affect the value of your units.
o Assuming no changes in interest rates, when you sell your
units, they will generally be worth less than your cost
because your cost included a sales fee.
o The Fund will receive early returns of principal if bonds
are called or sold before they mature. If this happens your
income will decline and you may not be able to reinvest the
money you receive at as high a yield or as long a maturity.

ALSO, THE PORTFOLIO IS CONCENTRATED IN BONDS OF FLORIDA SO
IT IS LESS DIVERSIFIED THAN A NATIONAL FUND AND IS SUBJECT
TO RISKS PARTICULAR TO FLORIDA WHICH ARE BRIEFLY DESCRIBED
UNDER STATE CONCENTRATION RISKS LATER IN THIS PROSPECTUS.

<PAGE>

5. IS THIS FUND APPROPRIATE FOR YOU?
Yes, if you want federally tax-free income. You will
benefit from a professionally selected and supervised
portfolio whose risk is reduced by investing in insured
bonds of several different issuers.
The Fund is not appropriate for you if you want a
speculative investment that changes to take advantage of
market movements, if you do not want a tax-advantaged
investment or if you cannot tolerate any risk.

DEFINING YOUR INCOME

WHAT YOU MAY EXPECT (Payable on the 25th day of
the month to holders of record on the 10th day
of the month):
Regular Monthly Income per unit $ 4.49
Annual Income per unit: $ 53.88
These figures are estimates determined on the evaluation
day; actual payments may vary.

6. WHAT ARE THE FUND'S FEES AND EXPENSES?
This table shows the costs and expenses you may pay,
directly or indirectly, when you invest in the Fund.
INVESTOR FEES
Maximum Sales Fee (Load) on new
purchases (as a percentage of
$1,000 invested) 2.90%
Employees of some of the Sponsors and their affiliates may

7. HOW HAVE SIMILAR FUNDS PERFORMED IN THE PAST?
In the following chart we show past performance of prior
Florida Portfolios, which had investment objectives,
strategies and types of bonds substantially similar to
this Fund. These prior Series differed in that they
charged a higher sales fee. These prior Florida Series
were offered between August 25, 1988 and December 6, 1996
and were outstanding on June 30, 1999. OF COURSE, PAST
PERFORMANCE OF PRIOR SERIES IS NO GUARANTEE OF FUTURE
RESULTS OF THIS FUND.

8. IS THE FUND MANAGED?
Unlike a mutual fund, the Fund is not managed and bonds are
not sold because of market changes. Rather, experienced
Defined Asset Funds financial analysts regularly review the
bonds in the Fund. The Fund may sell a bond if certain adverse
credit or other conditions exist.

4
<PAGE>

9. HOW DO I BUY UNITS?
The minimum investment is one unit.
You can buy units from any of the Sponsors and other
broker-dealers. The Sponsors are listed later in this
prospectus. Some banks may offer units for sale through
special arrangements with the Sponsors, although certain
legal restrictions may apply.
UNIT PRICE PER UNIT $1,059.91
(as of April 30, 1999)
Unit price is based on the net asset value of the Fund plus
the sales fee. An amount equal to any principal cash, as well
as net accrued but undistributed interest on the unit, is
added to the unit price. An independent evaluator prices the
bonds at 3:30 p.m. Eastern time every business day. Unit
price changes every day with changes in the prices of the
bonds in the Fund.
10. HOW DO I SELL UNITS?
You may sell your units at any time to any Sponsor or the
Trustee for the net asset value determined at the close of
business on the date of sale. You will not pay any other fee
when you sell your units.

11. HOW ARE DISTRIBUTIONS MADE AND TAXED?
The Fund pays income monthly.
In the opinion of bond counsel when each bond was issued,
interest on the bonds in this Fund is generally 100% exempt
from regular federal income tax. Your income may also be
exempt from some Florida state and local taxes if you live in
Florida.
You will also receive principal payments if bonds are sold or
called or mature, when the cash available is more than $5.00
per unit. You will be subject to tax on any gain realized by
the Fund on the disposition of bonds.
12. WHAT OTHER SERVICES ARE AVAILABLE?
REINVESTMENT
You will receive your income in cash unless you choose to
compound your income by reinvesting at no sales fee in the
Municipal Fund Investment Accumulation Program, Inc. This
program is an open-end mutual fund with a comparable
investment objective, but the bonds will generally not be
insured. Income from this program will generally be subject
to state and local income taxes. For more complete
information about the program, including charges and fees,
ask the Trustee for the program's prospectus. Read it
carefully before you invest. The Trustee must receive your
written election to reinvest at least 10 days before the
record day of an income payment.
EXCHANGE PRIVILEGES
You may exchange units of this Fund for units of certain
other Defined Asset Funds. You may also exchange into this
Fund from certain other funds. We charge a reduced sales fee
on exchanges.

federal and applicable State income tax rates and assumes that all income would
otherwise be taxed at the investor's highest tax rate. Yield figures are for
example only.

*Based upon net amount subject to federal income tax after deductions and
exemptions. This table does not reflect the possible effect of other tax
factors, such as alternative minimum tax, personal exemptions, the phase out of
exemptions, itemized deductions or the possible partial disallowance of
deductions. Consequently, you should consult your own tax advisers in this
regard.

<PAGE>
WHAT YOU CAN EXPECT FROM YOUR INVESTMENT

MONTHLY INCOME

The Fund will pay you regular monthly income. Your monthly income may vary
because of:
o elimination of one or more bonds from the Fund's portfolio because of
calls, redemptions or sales;
o a change in the Fund's expenses; or
o the failure by a bond's issuer to pay interest.

Changes in interest rates generally will not affect your income because the
portfolio is fixed.

Along with your income, you will receive your share of any available bond
principal.

RETURN FIGURES

We cannot predict your actual return, which will vary with unit price, how long
you hold your investment and changes in the portfolio, interest income and
expenses.

Estimated Current Return equals the estimated annual cash to be received from
the bonds in the Fund less estimated annual Fund expenses, divided by the Unit
Price (including the maximum sales fee):

Estimated Annual Estimated
Interest Income - Annual Expenses
- -------------------------------------------------
Unit Price

Estimated Long Term Return is a measure of the estimated return over the
estimated life of the Fund. Unlike Estimated Current Return, Estimated Long Term
Return reflects maturities, discounts and premiums of the bonds in the Fund. It
is an average of the yields to maturity (or in certain cases, to an earlier call
date) of the individual bonds in the portfolio, adjusted to reflect the Fund's
maximum sales fee and estimated expenses. We calculate the average yield for the
portfolio by weighting each bond's yield by its market value and the time
remaining to the call or maturity date.

Yields on individual bonds depend on many factors including general conditions
of the bond markets, the size of a particular offering and the maturity and
quality rating of the particular issues. Yields can vary among bonds with
similar maturities, coupons and ratings.

These return quotations are designed to be comparative rather than predictive.

RECORDS AND REPORTS

You will receive:
o a monthly statement of income payments and any principal payments;
o a notice from the Trustee when new bonds are deposited in exchange or
substitution for bonds originally deposited;
o an annual report on Fund activity; and
o annual tax information. This will also be sent to the IRS. You must report the
amount of tax-exempt interest received during the year.

You may request:
o copies of bond evaluations to enable you to comply with federal and state tax
reporting requirements; and
o audited financial statements of the Fund.

You may inspect records of Fund transactions at the Trustee's office during
regular business hours.

7
<PAGE>
THE RISKS YOU FACE

INTEREST RATE RISK

Investing involves risks, including the risk that your investment will decline
in value if interest rates rise. Generally, bonds with longer maturities will
change in value more than bonds with shorter maturities. Bonds in the Fund are
more likely to be called when interest rates decline. This would result in early
returns of principal to you and may result in early termination of the Fund. Of
course, we cannot predict how interest rates may change.

CALL RISK

Many bonds can be prepaid or 'called' by the issuer before their stated
maturity.

For example, some bonds may be required to be called pursuant to mandatory
sinking fund provisions.

Also, an issuer might call its bonds during periods of falling interest rates,
if the issuer's bonds have a coupon higher than current market rates.

An issuer might call its bonds in extraordinary cases, including if:
o it no longer needs the money for the original purpose;
o the project is condemned or sold;
o the project is destroyed and insurance proceeds are used to redeem the
bonds;
o any related credit support expires and is not replaced; or
o interest on the bonds become taxable.

If the bonds are called, your income will decline and you may not be able to
reinvest the money you receive at as high a yield or as long a maturity. An
early call at par of a premium bond will reduce your return.

REDUCED DIVERSIFICATION RISK

If many investors sell their units, the Fund will have to sell bonds. This could
reduce the diversification of your investment and increase your share of Fund
expenses.

LIQUIDITY RISK

You can always sell back your units, but we cannot assure you that a liquid
trading market will always exist for the bonds in the portfolio, especially
since current law may restrict the Fund from selling bonds to any Sponsor. The
bonds will generally trade in the over-the-counter market. The value of the
bonds, and of your investment, may be reduced if trading in bonds is limited or
absent.

CONCENTRATION RISK

When a certain type of bond makes up 25% or more of the portfolio, it is said to
be 'concentrated' in that bond type, which makes the Portfolio less diversified.

Here is what you should know about the Florida Portfolio's concentration in
hospital and health care bonds.
o payment for these bonds depends on revenues from private third-party payors
and government programs, including Medicare and Medicaid, which have
generally undertaken cost containment measures to limit payments to health
care providers;
o hospitals face increasing competition resulting from hospital mergers and
affiliations;
o hospitals need to reduce costs as HMOs increase market penetration and
hospital supply and drug companies raise prices;
o hospitals and health care providers are subject to various legal claims by
patients and others and are adversely affected by increasing costs of
insurance; and

8
<PAGE>
o many hospitals are aggressively buying physician practices and assuming
risk contracts to gain market share. If revenues do not increase
accordingly, this practice could reduce profits;
o Medicare is changing its reimbursement system for nursing homes. Many
nursing home providers are not sure how they will be treated. In many
cases, the providers may receive lower reimbursements and these would have
to cut expenses to maintain profitability; and
o most retirement/nursing home providers rely on entrance fees for operating
revenues. If people live longer than expected and turnover is lower than
budgeted, operating revenues would be adversely affected by less than
expected entrance fees.

Here is what you should know about the Florida Portfolio's concentration in
municipal electric utility revenue bonds. The payment of interest and principal
of these bonds depends on the rates the utilities may charge, the demand for
their services and the cost of operating their business which includes the
expense of complying with environmental and other energy and licensing laws and
regulations. The operating results of utilities are particularly influenced by:
o increases in operating and construction costs;
o the costs and availability of fuel;
o unpredicability of future usage requirements; and
o the risks associated with the nuclear industry.

There has been an increase in competition in the electric utility industry. The
effect of this competition has been to induce municipal utilities to keep their
rates as low as possible. Municipal electric utilities may, therefore, be unable
to increase rates to recover their investment in generating plant.

Changes to the portfolio from bond redemptions, maturities and sales may affect
the Fund's concentrations over time.

STATE CONCENTRATION RISK

FLORIDA RISKS

Generally

Florida's financial condition is affected by numerous national, economic, social
and environmental policies and conditions. For example:

o south Florida is heavily involved with foreign tourism, trade and
investment capital. As a result, the region is susceptible to international
trade and currency imbalances and economic problems in Central and South
America;

o central and northern Florida are more vulnerable to agricultural problems,
such as crop failures or severe weather conditions, especially in the
citrus and sugar industries; and

o the state as a whole is also very dependent on tourism and construction.

State and Local Government

The state of Florida and its local governments are restricted in their ability
to raise taxes and incur debts. These restrictions limit their ability to
generate revenue, and so could hurt their ability to pay debts.

General obligations of the state are rated Aa2 by Moody's, AA+ by Standard &
Poor's and AA by Fitch.

BOND QUALITY RISK

A reduction in a bond's rating may decrease its value and, indirectly, the value
of your investment in the Fund.

9
<PAGE>
INSURANCE RELATED RISK

The bonds are backed by insurance companies (as shown under Portfolio).
Insurance policies generally make payments only according to a bond's original
payment schedule and do not make early payments when a bond defaults or becomes
taxable. Although the federal government does not regulate the insurance
business, various state laws and federal initiatives and tax law changes could
significantly affect the insurance business. The claims-paying ability of the
insurance companies is generally rated A or better by Standard & Poor's or
another nationally recognized rating organization. The insurance company ratings
are subject to change at any time at the discretion of the rating agencies.

LITIGATION AND LEGISLATION RISKS

We do not know of any pending litigation that might have a material adverse
effect upon the Fund.

Future tax legislation could affect the value of the portfolio by:
o limiting real property taxes,
o reducing tax rates,
o imposing a flat or other form of tax, or
o exempting investment income from tax.

SELLING OR EXCHANGING UNITS

You can sell your units at any time for a price based on net asset value. Your
net asset value is calculated each business day by:
o adding the value of the bonds, net accrued interest, cash and any other
Fund assets;
o subtracting accrued but unpaid Fund expenses, unreimbursed Trustee
advances, cash held to buy back units or for distribution to investors and
any other Fund liabilities; and
o dividing the result by the number of outstanding units.

Your net asset value when you sell may be more or less than your cost because of
sales fees, market movements and changes in the portfolio.

SPONSORS' SECONDARY MARKET

While we are not obligated to do so, we will buy back units at net asset value
without any other fee or charge. We may resell the units to other buyers or to
the Trustee. You should consult your financial professional for current market
prices to determine if other broker-dealers or banks are offering higher prices.

We have maintained the secondary market continuously for over 25 years, but we
could discontinue it without prior notice for any business reason.

SELLING UNITS TO THE TRUSTEE

Regardless of whether we maintain a secondary market, you can sell your units to
the Trustee at any time by sending the Trustee a letter (with any outstanding
certificates if you hold Unit certificates). You must properly endorse your
certificates (or execute a written transfer instrument with signatures
guaranteed by an eligible institution). Sometimes, additional documents are
needed such as a trust document, certificate of corporate authority, certificate
of death or appointment as executor, administrator or guardian.

Within seven days after your request and the necessary documents are received,
the Trustee will mail a check to you. Contact the Trustee for additional
information.

As long as we are maintaining a secondary market, the Trustee will sell your
units to us at a price based on net asset value. If there is no secondary
market, the Trustee may sell your

10
<PAGE>
units in the over-the-counter market for a higher price, but it is not obligated
to do so. In that case, you will receive the net proceeds of the sale.

If the Fund does not have cash available to pay you for units you are selling,
the agent for the Sponsors will select bonds to be sold. Bonds will be selected
based on market and credit factors. These sales could be made at times when the
bonds would not otherwise be sold and may result in your receiving less than the
unit par value and also reduce the size and diversity of the Fund.

There could be a delay in paying you for your units:
o if the New York Stock Exchange is closed (other than customary weekend and
holiday closings);
o if the SEC determines that trading on the New York Stock Exchange is
restricted or that an emergency exists making sale or evaluation of the
bonds not reasonably practicable; and
o for any other period permitted by SEC order.

EXCHANGE OPTION

You may exchange units of certain Defined Asset Funds for units of this Fund at
a maximum exchange fee of 1.90%. You may exchange units of this Fund for units
of certain other Defined Asset Funds at a reduced sales fee if your investment
goals change. To exchange units, you should talk to your financial professional
about what funds are exchangeable, suitable and currently available.

Normally, an exchange is taxable and you must recognize any gain or loss on the
exchange. However, the IRS may try to disallow a loss if the portfolios of the
two funds are not materially different; you should consult your own tax adviser.

We may amend or terminate this exchange option at any time without notice.

HOW THE FUND WORKS

PRICING

The price of a unit includes interest accrued on the bonds, less expenses, from
the initial most recent Record Day up to, but not including, the settlement
date, which is usually three business days after the purchase date of the unit.

A portion of the price of a unit consists of cash so that the Trustee can
provide you with regular monthly income. When you sell your units you will
receive your share of this cash.

EVALUATIONS

An independent Evaluator values the bonds on each business day (excluding
Saturdays, Sundays and the following holidays as observed by the New York Stock
Exchange: New Year's Day, Presidents' Day, Martin Luther King, Jr. Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas).
Bond values are based on current bid or offer prices for the bonds or comparable
bonds. In the past, the difference between bid and offer prices of publicly
offered tax-exempt bonds has ranged from 0.5% of face amount on actively traded
issues to 3.5% on inactively traded issues; the difference has averaged between
1 and 2%.

11
<PAGE>
INCOME

The Trustee credits interest to an Income Account and other receipts to a
Capital Account. The Trustee may establish a Reserve Account by withdrawing from
these accounts amounts it considers appropriate to pay any material liability.
These accounts do not bear interest.

EXPENSES

The Trustee is paid monthly. It also benefits when it holds cash for the Fund in
non-interest bearing accounts. The Trustee may also receive additional amounts:
o to reimburse the Trustee for the Fund's operating expenses;
o for extraordinary services and costs of indemnifying the Trustee and the
Sponsors;
o costs of actions taken to protect the Fund and other legal fees and
expenses;
o expenses for keeping the Fund's registration statement current; and
o Fund termination expenses and any governmental charges.

The Sponsors are currently reimbursed up to 55 cents per $1,000 face amount
annually for providing portfolio supervisory, bookkeeping and administrative
services and for any other expenses properly chargeable to the Fund. Legal,
typesetting, electronic filing and regulatory filing fees and expenses
associated with updating the Portfolio's registration statement yearly are also
now chargeable to the Portfolio. While this fee may exceed the amount of these
costs and expenses attributable to this Fund, the total of these fees for all
Series of Defined Asset Funds will not exceed the aggregate amount attributable
to all of these Series for any calendar year. The Fund also pays the Evaluator's
fees.

The Trustee's, Sponsors' and Evaluator's fees may be adjusted for inflation
without investors' approval.

The Sponsors will pay advertising and selling expenses at no charge to the Fund.
If Fund expenses exceed initial estimates, the Fund will owe the excess. The
Trustee has a lien on Fund assets to secure reimbursement of Fund expenses and
may sell bonds if cash is not available.

PORTFOLIO CHANGES

The Sponsors and Trustee are not liable for any default or defect in a bond; if
a contract to buy any bond.

Unlike a mutual fund, the portfolio is designed to remain intact and we may keep
bonds in the portfolio even if their credit quality declines or other adverse
financial circumstances occur. However, we may sell a bond in certain cases if
we believe that certain adverse credit conditions exist or if a bond becomes
taxable.

If we maintain a secondary market in units but are unable to sell the units that
we buy in the secondary market, we will redeem units, which will affect the size
and composition of the portfolio. Units offered in the secondary market may not
represent the same face amount of bonds that they did originally.

We decide whether or not to offer units for sale that we acquire in the
secondary market after reviewing:
o diversity of the portfolio;
o size of the Fund relative to its original size;
o ratio of Fund expenses to income;

12
<PAGE>
o current and long-term returns;
o degree to which units may be selling at a premium over par; and
o cost of maintaining a current prospectus.

FUND TERMINATION

The Fund will terminate following the stated maturity or sale of the last bond
in the portfolio. The Fund may also terminate earlier with the consent of
investors holding 51% of the units or if total assets of the Fund have fallen
below 40% of the face amount of bonds deposited. We will decide whether to
terminate the Fund early based on the same factors used in deciding whether or
not to offer units in the secondary market.

When the Fund is about to terminate you will receive a notice, and you will be
unable to sell your units after that time. On or shortly before termination, we
will sell any remaining bonds, and you will receive your final distribution. Any
bond that cannot be sold at a reasonable price may continue to be held by the
Trustee in a liquidating trust pending its final sale.

You will pay your share of the expenses associated with termination, including
brokerage costs in selling bonds. This may reduce the amount you receive as your
final distribution.

CERTIFICATES

Certificates for units are issued on request. You may transfer certificates by
complying with the requirements for redeeming certificates, described above. You
can replace lost or mutilated certificates by delivering satisfactory indemnity
and paying the associated costs.

TRUST INDENTURE

The Fund is a 'unit investment trust' governed by a Trust Indenture, a contract
among the Sponsors, the Trustee and the Evaluator, which sets forth their duties
and obligations and your rights. A copy of the Indenture is available to you on
request to the Trustee. The following summarizes certain provisions of the
Indenture.

The Sponsors and the Trustee may amend the Indenture without your consent:
o to cure ambiguities;
o to correct or supplement any defective or inconsistent provision;
o to make any amendment required by any governmental agency; or
o to make other changes determined not to be materially adverse to your best
interest (as determined by the Sponsors).

Investors holding 51% of the units may amend the Indenture. Every investor must
consent to any amendment that changes the 51% requirement. No amendment may
reduce your interest in the Fund without your written consent.

The Trustee may resign by notifying the Sponsors. The Sponsors may remove the
Trustee without your consent if:
o it fails to perform its duties and the Sponsors determine that its
replacement is in your best interest; or
o it becomes incapable of acting or bankrupt or its affairs are taken over by
public authorities.
Investors holding 51% of the units may remove the Trustee. The Evaluator may
resign or be removed by the Sponsors and the Trustee without the consent of
investors. The resignation or removal of either becomes

13
<PAGE>
effective when a successor accepts appointment. The Sponsors will try to appoint
a successor promptly; however, if no successor has accepted within 30 days after
notice of resignation, the resigning Trustee or Evaluator may petition a court
to appoint a successor.

Any Sponsor may resign as long as one Sponsor with a net worth of $2 million
remains and agrees to the resignation. The remaining Sponsors and the Trustee
may appoint a replacement. If there is only one Sponsor and it fails to perform
its duties or becomes bankrupt the Trustee may:
o remove it and appoint a replacement Sponsor;
o liquidate the Fund; or
o continue to act as Trustee without a Sponsor.

Merrill Lynch, Pierce, Fenner & Smith Incorporated acts as agent for the
Sponsors.

The Trust Indenture contains customary provisions limiting the liability of the
Trustee, the Sponsors and the Evaluator.

LEGAL OPINION

issued. Special counsel located in the relevant states have given state and
local tax opinions.

Deloitte & Touche LLP, 2 World Financial Center, New York, New York 10281,
independent accountants, audited the Statements of Condition included in this
prospectus.

SPONSORS

The Sponsors are:
MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED (a wholly-owned subsidiary of
Merrill Lynch & Co., Inc.)
P.O. Box 9051,
Princeton, NJ 08543-9051

Each Sponsor is a Delaware corporation and it, or its predecessor, has acted as
sponsor to many unit investment trusts. As a registered broker-dealer each
Sponsor buys and sells securities (including investment company shares) for
others (including investment companies) and participates as an underwriter in
various selling groups.

TRUSTEE

The Chase Manhattan Bank, Unit Investment Trust Department, 4 New York
Plaza--6th Floor, New York, New York 10004, is the Trustee. It is supervised by
the Federal Deposit Insurance Corporation, the Board of

14
<PAGE>
Governors of the Federal Reserve System and New York State banking authorities.

UNDERWRITERS' AND SPONSORS' PROFITS

Underwriters receive sales charges when they sell units. The Sponsors also
realized a profit or loss on the initial date of deposit of the bonds. Any cash
made available by you to the Sponsors before the settlement date for those units
may be used in the Sponsors' businesses to the extent permitted by federal law
and may benefit the Sponsors.

A Sponsor or Underwriter may realize profits or sustain losses on bonds in the
Fund which were acquired from underwriting syndicates of which it was a member.

In maintaining a secondary market, 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 or redeem them.

PUBLIC DISTRIBUTION

The Sponsors do not intend to qualify units for sale in any foreign countries.
This prospectus does not constitute an offer to sell units in any country where
units cannot lawfully be sold.

CODE OF ETHICS

Merrill Lynch, as agent for the Sponsors, has adopted a code of ethics requiring
preclearance and reporting of personal securities transactions by its employees
with access to information on portfolio transactions. The goal of the code is to
prevent fraud, deception or misconduct against the Fund and to provide
reasonable standards of conduct.

YEAR 2000 ISSUES

Many computer systems were designed in such a way that they may be unable to
distinguish between the year 2000 and the year 1900 (commonly known as the 'Year
2000 Problem'). We do not expect that the computer system changes necessary to
prepare for the Year 2000 will cause any major operational difficulties for the
Fund. The Year 2000 Problem may adversely affect the issuers of the securities
contained in the Portfolio, but we cannot predict whether any impact will be
material to the Portfolio as a whole.

TAXES

The following summary describes some of the important income tax consequences of
holding units. It assumes that you are not a dealer in securities, financial
institution, insurance company or other investor with special circumstances. You
should consult your own tax adviser about your particular circumstances.

At the date of issue of each bond, counsel for the issuer delivered an opinion
to the effect that interest on the bond is exempt from regular federal income
tax. However, interest may be subject to state and local taxes and federal
alternative minimum tax. Neither we nor our counsel have reviewed the issuance
of the bonds, related proceedings or the basis for the opinions of counsel for
the issuers. We cannot assure you that the issuer (or other users) have complied
or will comply with any requirements necessary for a bond to be tax-exempt. If
any of the bonds were determined not to be tax-exempt, you could be required to
pay income tax for current and prior years,

15
<PAGE>
and if the Fund were to sell the bond, it might have to sell it at a substantial
discount.

In the opinion of our counsel, under existing law:

GENERAL TREATMENT OF THE FUND AND YOUR INVESTMENT

The Fund will not be taxed as a corporation for federal income tax purposes, and
you will be considered to own directly your share of each bond in the Fund.

INCOME OR LOSS UPON DISPOSITION

When all or part of your share of a bond is disposed of (for example, when the
Fund sells, exchanges or redeems a bond or when you sell or exchange your
units), you will generally recognize capital gain or loss. Your gain, however,
will generally be ordinary income to the extent of any accrued 'market
discount'. Generally you will have market discount to the extent that your basis
in a bond when you purchase a unit is less than its stated redemption price at
maturity (or, if it is an original issue discount bond, the issue price
increased by original issue discount that has accrued on the bond before your
purchase). You should consult your tax adviser in this regard.

If your net long-term capital gains exceed your net short-term capital losses,
the excess may be subject to tax at a lower rate than ordinary income. Any
capital gain from the Fund will be long-term if you are considered to have held
your investment on each bond for more than one year and short-term if you held
it for one year or less. If you are an individual and sell your units after
holding them for more than one year, you may be entitled to a 20% maximum
federal tax rate on any resulting gains. Consult your tax adviser in this
regard. Because the deductibility of capital losses is subject to limitations,
you may not be able to deduct all of your capital losses.

YOUR BASIS IN THE BONDS

Your aggregate basis in the bonds will be equal to the cost of your units,
including any sales charges and the organizational expenses you pay, adjusted to
reflect any accruals of 'original issue discount,' 'acquisition premium' and
'bond premium'. You should consult your tax adviser in this regard.

EXPENSES

If you are not a corporate investor, you will not be entitled to a deduction for
your share of fees and expenses of the Fund. Also, if you borrowed money in
order to purchase or carry your units, you will not be able to deduct the
interest on this borrowing for federal income tax purposes. The IRS may treat
your purchase of units as made with borrowed money even if the money is not
directly traceable to the purchase of units.

STATE AND LOCAL TAXES

Under the income tax laws of the State and City of New York, the Fund will not
be taxed as a corporation. If you are a New York taxpayer, your income from the
Fund will not be tax-exempt in New York except to the extent that the income is
earned on bonds that are tax-exempt for New York purposes. Depending on where
you live, your income from the Fund may be subject to state and local taxation.
You should consult your tax adviser in this regard.

16
<PAGE>
FLORIDA TAXES

In the opinion of Greenberg, Traurig, P.A., Miami, Florida, special counsel on
Florida tax matters:

Under the income tax laws of the State of Florida, the Fund will not be taxed as
a corporation. Florida imposes an income tax on corporations but does not impose
a personal income tax. Accordingly, if you are an individual taxpayer your
income from the Fund will not be subject to tax in Florida. However, if you are
an entity that is normally taxed as a corporation, your income from the fund
will not be exempt from tax in Florida and special rules for taxation apply
depending on the type of entity. You should consult your tax adviser in this
regard.

Florida also imposes a tax on intangible personal property, such as stocks,
bonds, notes and units in trusts. The tax is imposed on Florida taxpayers as of
January 1st of each year. Florida exempts certain types of bonds and debt
obligations from this tax. Your units will be exempt from the intangible
personal property tax as long as the Fund invests exclusively in bonds and other
debt obligations that are tax-exempt for Florida purposes.

SUPPLEMENTAL INFORMATION

You can receive at no cost supplemental information about the Fund by calling
the Trustee. The supplemental information includes more detailed risk disclosure
about the types of bonds that may be in the Fund's portfolios, general risk
disclosure concerning any insurance securing certain bonds, and general
information about the structure and operation of the Fund. The supplemental
information is also available from the SEC.

NOTES TO PORTFOLIO
As of April 30, 1999

(1) The ratings of the bonds are by Standard & Poor's Ratings Group, or by
Moody's Investors Service, Inc. if followed by "(m)", or by Fitch
Investors Service, Inc. if followed by "(f)"; "NR" indicates that this
bond is not currently rated by any of the above-mentioned rating services.
These ratings have been furnished by the Evaluator but not confirmed with
the rating agencies.

(2) See Notes to Financial Statements.

(3) Optional redemption provisions, which may be exercised in whole or in
part, are initially at prices of par plus a premium, then subsequently at
prices declining to par. Certain securities may provide for redemption at
par prior or in addition to any optional or mandatory redemption dates or
maturity, for example, through the operation of a maintenance and
replacement fund, if proceeds are not able to be used as contemplated,the
project is condemned or sold or the project is destroyed and insurance
proceeds are used to redeem the securities. Many of the securities are also
subject to mandatory sinking fund redemption commencing on dates which may
be prior to the date on which securities may be optionally redeemed. Sinking
fund redemptions are at par and redeem only part of the issue. Some of the
securities have mandatory sinking funds which contain optional provisions
permitting the issuer to increase the principal amount of securities 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 securities have an offering side evaluation which
represents a premium over par. To the extent that the securities were
acquired at a price higher than the redemption price, this will represent a
loss of capital when compared with the Public Offering Price of the Units
when acquired. Distributions will generally be reduced by the amount of the
income which would otherwise have been paid with respect to redeemed
securities and there will be distributed to Holders any principal amount and
premium received on such redemption after satisfying any redemption requests
for Units received by the Fund. The estimated current return may be affected
by redemptions.

(4) All securities are insured, either on an individual basis or by portfolio
insurance, by a municipal bond insurance company which has been assigned
"AAA" claims paying ability by Standard & Poor's. Accordingly, Standard &
Poor's has assigned "AAA" ratings to the securities. Securities covered by
portfolio insurance are rated "AAA" only as long as they remain in this Trust.

(5) Bonds with an aggregate face amount of $455,000 have been pre-refunded
and are expected to be called for redemption on the optional redemption
provision date shown.
