California Insured Portfolio--Risk/Return Summary

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
$4,000,000, and some short-term bonds reserved to pay the
deferred sales fee. The Fund is a unit investment trust
which means that, unlike a mutual fund, the Fund's
portfolio is not managed.
o The bonds are rated AAA or Aaa by Standard & Poor's,
Moody's or Fitch.
o Most of the bonds cannot be called for several years, and
after that they 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 AAA-rated 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

o General Obligation 45%
o Hospital/Health Care 24%
o Lease Rental 16%
o Municipal Water/Sewer Utilities 15%

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 The fund is concentrated in general obligation bonds. These
risks are discussed later in this prospectus under
Concentration Risk.
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 California bonds so
it is less diversified than a national fund and is subject
to risks particular to California which are briefly
described on page 16.

principal.
(3) Approximately 2% of the bonds were deposited at a premium and 98% at a
discount from par. Sponsors' profit on deposit was $25,034.90.
(4) The interest and principal on these bonds will be used to pay the deferred

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%
You will pay an up-front sales fee of 1.00%, as well as a
total deferred sales fee of $19.00 per 1,000 units ($2.38
per 1,000 units quarterly in the first year and $2.37 per

The Sponsors historically paid organization costs and
updating expenses.
Example
This example may help you compare the cost of investing in
the Fund to the cost of investing in other funds.
The example assumes that you invest $10,000 in the Fund for
the periods indicated and sell all your units at the end of
those periods. The example also assumes a 5% return on your
investment each year and that the Fund's operating expenses
stay the same. Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

1 Year 3 Years 5 Years 10 Years
$328 $366 $408 $531

You will pay the following expenses if you do not sell your
units:

1 Year 3 Years 5 Years 10 Years
$233 $366 $408 $531

7. How have Similar Funds Performed in the Past?
In the following chart we show past performance of prior
California 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 California Series were offered
between June 22, 1988 and September 27, 1996 and were
outstanding on March 31, 1999. Of course, past performance
of prior Series is no guarantee of future results of this
Fund.

California Insured Portfolio (continued)

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.
9. How do I Buy Units?
The minimum investment is $250.
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 1,000 Units $998.20
(as of June 10, 1999)
Unit price is based on the net asset value of the Fund plus
the up-front 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. Unit price also
includes the estimated organization costs shown on page 4,
to which no sales fee has been applied. 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.
Unit Par Value $1.00
Unit par value means the total amount of money you should
generally receive on each unit by the termination of the
Fund (other than interest and premium on the bonds). This
total amount assumes that all bonds in the Fund are either
paid at maturity or called by the issuer at par or are sold
by the Fund at par. If you sell your units before the Fund
terminates, you may receive more or less than the unit par
value.

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, less any remaining deferred
sales fee. You will not pay any other fee when you sell your
units.

11. How are Distributions Made and Taxed?
The Fund pays income twice a year.
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 California state and local personal income
taxes if you live in California.
You will also receive principal payments if bonds are sold
or called or mature, when the cash available is more than
$10.00 per 1,000 units. 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 with no sales fee in the
Municipal Fund Investment Accumulation Program, Inc. This
program is an open-end mutual fund with a comparable
investment objective. 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.

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 20-
to 30-year 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
$3,250,000, and some short-term bonds reserved to pay the
deferred sales charge. The Fund is a unit investment trust
which means that, unlike a mutual fund, the Fund's
portfolio is not managed.
o The bonds are rated AAA or Aaa by Standard & Poor's,
Moody's or Fitch.
o Most of the bonds cannot be called for several years, and
after that they 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 AAA-rated 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

Percentage

o Airports/Ports/Highways 30%
o Hospitals/Health Care 15%
o Lease Rental 15%
o Municipal Electric Utilities 15%
o Municipal Water/Sewer Utilities 24%
o Special Tax 1%

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 airport/port/highway
bonds, adverse developments in this sector may affect the
value of your units. These risks are discussed later in
this prospectus under Concentration Risk.
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 Florida bonds, so it
is less diversified than a national fund and is subject to
risks particular to Florida, which are briefly described on
page 16.

Florida Insured Portfolio (Continued)

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 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.
6. What are the Fund's Fees and Expenses?

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 March 31, 1999. Of course, past performance
of prior Series is no guarantee of future results of this
Fund.

Florida Insured Portfolio (continued)

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.
9. How do I Buy Units?
The minimum investment is $250.
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 1,000 Units $993.59
(as of June 10, 1999)
Unit price is based on the net asset value of the Fund
plus the up-front 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. Unit
price also includes the estimated organization costs shown
on page 7, to which no sales fee has been applied. 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.
Unit Par Value $1.00
Unit par value means the total amount of money you should
generally receive on each unit by the termination of the
Fund (other than interest and premium on the bonds). This
total amount assumes that all bonds in the Fund are either
paid at maturity or called by the issuer at par or are
sold by the Fund at par. If you sell your units before the
Fund terminates, you may receive more or less than the
unit par value.

11. How are Distributions Made and Taxed?
The Fund pays income twice a year.
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 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
$10.00 per 1,000 units. 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. 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.

New York Insured Portfolio--Risk/Return Summary

The Portfolio consists of municipal bonds of the following
types:

Approximate
Portfolio
Percentage

o Airports/Ports/Highways 15%
o General Obligation 16%
o Hospitals/Health Care 8%
o Industrial Development Revenues 15%
o Municipal Water/Sewer Utilities 15%
o Municipal Electric Utilities 15%
o Universities/Colleges 16%

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 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 New York bonds so it
is less diversified than a national fund and is subject to
risks particular to New York which are briefly described on
page 17.

To compare the yield of a taxable security with the yield of a tax-free
security, find your taxable income and read across. The table incorporates 1999
federal and applicable State (and City) 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, investors are urged to consult their own tax advisers
in this regard.

<PAGE>
What You Can Expect From Your Investment

Income Twice A Year

The Fund will pay you regular income twice a year. Your 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 statement of income payments twice a year;
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.

13
<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.

Transportation Bonds

Here is what you should know about the Florida's concentration in airport, port
and highway bonds. Airport, port and highway revenue bonds are dependent for
payment on revenues from financial projects including:
o user fees from ports and airports;
o tolls on turnpikes and bridges;
o rents from buildings; and
o additional financial resources including
--federal and state subsidies,
--lease rentals paid by state or local governments, or
--the pledge of a special tax such as a sales tax or a property tax.

Airport income is largely affected by:
o increased competition;
o excess capacity; and
o increased fuel costs.

14
<PAGE>

Here is what you should know about the California's concentration in general
obligation bonds:
o general obligation bonds are backed by the issuer's pledge of its full
faith, credit and taxing power;
o but the taxing power of any government issuer may be limited by provisions
of the state constitution or laws as well as political and economic
considerations; and
o an issuer's credit can be negatively affected by various factors, including
population decline that erodes the tax base, natural disasters, decline in
industry, limited access to capital markets or heavy reliance on state or
federal aid.

State Concentration Risks

California Risks

Generally

From the late 1980s through the early 1990s, an economic recession eroded
California's revenue base. At the same time rapid population growth caused State
expenditures to exceed budget appropriations.

o As a result California experienced a period of sustained budget imbalance.

o Since that time the California economy has improved markedly and the
extreme budgetary pressures have begun to lessen. However, the Asian
economic crisis is expected to continue to have some negative effect on the
State's economy.

State Government

The 1997-98 Budget Act allocated a State budget of approximately $66.9 Billion
and contains no tax increases or reductions. Despite this somewhat improved
state, California's budget is still subject to certain unforeseeable events. For
example:

o In December, 1994, Orange County and its investment pool filed for
bankruptcy. While a settlement has been reached, the full impact on the
State and Orange County is still unknown.

o California faces constant fluctuations in other expenses (including health
and welfare caseloads, property tax receipts, federal funding and natural
disaster relief) that will undoubtedly create new budgetary pressure and
reduce ability to pay their debts.

o California's general obligation bonds are currently rated AA3 by Moody's
and A+ by Standard & Poor's.

Other Risks

Issuers' ability to make payments on bonds (and the remedies available to
bondholders) could also be adversely affected by the following constraints:

o Certain provisions of California's Constitution, laws and regulatory system
contain tax, spending and appropriations limits and prohibit certain new
taxes.

o Certain other California laws subject the users of bond proceeds to strict
rules and limits regarding revenue repayment.

o Bonds of healthcare institutions which are subject to the strict rules and
limits regarding reimbursement payments of California's Medi-Cal program
for health care services to welfare recipients and bonds secured by liens
on real property are two of the types of bonds that could be affected by
these provisions.

15
<PAGE>

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.

New York Risks

Generally

For decades, New York's economy has trailed the rest of the nation. Both the
state and New York City have experienced long-term structural imbalances between
revenues and expenses, and have repeatedly relied substantially on non-recurring
measures to achieve budget balance. The pressures that contribute to budgetary
problems at both the state and local level include:

o the high combined state and local tax burden;

o a decline in manufacturing jobs, leading to above-average unemployment;

o sensitivity to the financial services industry; and

o dependence on federal aid.

State Government

The State government frequently has difficulty approving budgets on time. Budget
gaps of $3 billion and $5 billion are projected for the next two years. The
State's general obligation bonds are rated A by Standard & Poor's and A2 by
Moody's. There is $37 billion of state-related debt outstanding.

New York City Government

Even though the City had budget surpluses each year from 1981, budget gaps of
about $2 billion are projected for the 2001 and 2002 fiscal years. New York City
faces fiscal pressures from:

o aging public facilities that need repair or replacement;

o welfare and medical costs;

o expiring labor contracts; and

o a high and increasing debt burden.

The City requires substantial state aid, and its fiscal strength depends heavily
on the securities industry. Its general obligation bonds are rated A-by Standard
& Poor's and A3 by Moody's. $30.7 billion of combined City, MAC and PBC debt is
outstanding, and the City proposes $23 billion of financing over fiscal
1999-2003.

16
<PAGE>
Bond Quality Risk

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

Insurance Related Risk

All of the bonds are backed by insurance companies (as shown under Defined
Portfolios). 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 AAA 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.

As of the close of the initial offering period, the price you receive will be
reduced to reflect estimated organization costs.

If you sell your units before the final deferred sales fee installment, the
amount of any remaining installments will be deducted from your proceeds.

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 other than any remaining deferred sales 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

17
<PAGE>
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 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.

If you acquire 25% or more of the outstanding units of the Fund and you sell
units with a value exceeding $250,000, the Trustee may choose to pay you 'in
kind' by distributing bonds and cash with a total value equal to the price of
those units. The Trustee will try to distribute bonds in the portfolio pro rata,
but it reserves the right to distribute only one or a few bonds. The Trustee
will act as your agent in an in kind distribution and will either hold the bonds
for your account or sell them as you instruct. You must pay any transaction
costs as well as transfer and ongoing custodial fees on sales of bonds
distributed in kind.

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 date of deposit up to, but not including, the settlement date, which
is usually three business days after the purchase date of the unit.

Bonds also carry accrued but unpaid interest up to the initial date of deposit.
To avoid

18
<PAGE>
having you pay this additional accrued interest (which earns no return) when you
buy, the Trustee advances this amount to the Sponsors. The Trustee recovers this
advance from interest received on the bonds.

In addition, a portion of the price of a unit also consists of cash to pay all
or some of the costs of organizing the Fund including:
o cost of initial preparation of legal documents;
o federal and state registration fees;
o initial fees and expenses of the Trustee;
o initial audit; and
o legal expenses and other out-of-pocket expenses.

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%.

Income

Interest on any bonds purchased on a when-issued basis or for a delayed delivery
does not begin to accrue until the bonds are delivered to the Fund. The Trustee
may reduce its fee to provide you with tax-exempt income for this non-accrual
period. If a bond is not delivered on time and the Trustee's annual fee and
expenses do not cover the additional accrued interest, we will treat the
contract to buy the bond as failed.

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 45 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 Fund's registration statement yearly are also now
chargeable to the Fund. 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. Certain of these expenses were previously
paid for by the

19
<PAGE>
Sponsors. The Fund also pays the Evaluator's fees.

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

Quarterly deferred sales fees you owe are paid with interest and principal from
certain bonds. If these amounts are not enough, the rest will be paid out of
distributitons to you from the Fund's Capital and Income Accounts.

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 fails in the first 90 days of the Fund, we generally
will deposit a replacement tax-exempt bond with a similar yield, maturity,
rating and price.

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;
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

20
<PAGE>
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 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

Davis Polk & Wardwell, 450 Lexington Avenue, New York, New York 10017, as
counsel for the Sponsors, has given an opinion that the units are validly
issued. Special counsel located in the relevant states have given state and
local tax opinions.

Auditors

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 and their underwriting percentages are:
Merrill Lynch, Pierce, Fenner & Smith Incorporated (a wholly-owned subsidiary of
Merrill Lynch & Co., Inc.)
P.O. Box 9051,
Princeton, NJ 08543-9051 53.78%
Salomon Smith Barney Inc. (an indirectly wholly-owned subsidiary of Citigroup
Inc.)
388 Greenwich Street--23rd Floor,
New York, NY 10013 13.78%
Dean Witter Reynolds Inc. (a principal operating subsidiary of Morgan Stanley
Dean Witter & Co.)
Two World Trade Center--59th Floor,
New York, NY 10048 10.22%
PaineWebber Incorporated (a wholly-owned subsidiary of PaineWebber Group Inc.)
1285 Avenue of the Americas,
New York, NY 10019 22.22%
100.00%

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 Bank of New York, Unit Investment Trust Department, P.O. Box 974, Wall
Street Division, New York, New York 10268-0974 is the Trustee. It is supervised
by the Federal Deposit Insurance Corporation, the Board of Governors of the
Federal Reserve System and New York State banking authorities.

Underwriters' and Sponsors' Profits

Underwriters receive sales charges when they sell units. Sponsors also realize a
profit or loss on deposit of the bonds shown under Defined Portfolios. 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.
None of the bonds in the Fund were purchased from any of the Sponsors.

During the initial offering period, the Sponsors also may realize profits or
sustain losses on units they hold. 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

During the initial offering period, units will be distributed to the public by
the Sponsors and dealers who are members of the National Association of
Securities Dealers, Inc. This period is 30 days or less if all units are sold.
The Sponsors may extend the initial period up to 120 days.

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.

In the initial offering period, the concession to dealers will be $21 per 1,000
units. We may change the concession at any time. Dealers may resell units to
other dealers with a concession not in excess of the original concession to
dealers.

22
<PAGE>
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, 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 of bond
proceeds) 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, 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.

Gain 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

23
<PAGE>
your investment on each bond for more than one year and short-term otherwise. 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.

California Taxes

In the opinion of O'Melveny & Myers LLP, Los Angeles, California, special
counsel on California tax matters:

Under the income tax laws of the State of California, the Trust will not be
taxed as a corporation and you will be considered to own directly your share of
each bond of the Trust. If you are a California taxpayer, your share of the
income from the bonds of the Trust will not be tax-exempt in California except
for California personal income tax purposes and only to the extent that the
income is earned on bonds that are exempt for such purposes. If you are a
California taxpayer and all or part of your share of a bond is disposed of (for
example, when a bond is sold, exchanged or redeemed at maturity or you sell or
exchange your units), you will recognize gain or loss for California tax
purposes. Depending on where you live, your income from the Trust may be subject
to state and local taxation. You should consult your tax advisor in this regard.

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

24
<PAGE>
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.

REPORT OF INDEPENDENT ACCOUNTANTS

The Sponsors, Trustee and Holders of Municipal Investment Trust Fund, Multistate
Series--408, Defined Asset Funds (California, Florida and New York Insured
Trusts) (the 'Fund'):

We have audited the accompanying statements of condition and the related defined
portfolios included in the prospectus of the Fund as of June 11, 1999. 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 audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of cash, securities and an irrevocable letter of credit deposited
for the purchase of securities, as described in the statements of condition,
with the Trustee. An audit also includes assessing the accounting principles
used and significant estimates made by the Trustee, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Fund as of June 11, 1999 in
conformity with generally accepted accounting principles.

(1) Aggregate cost to the Fund of the bonds listed under each portfolio is
based upon the offer side evaluation determined by the Evaluator at the
evaluation time on the business day prior to the initial date of deposit. The
contracts to purchase the bonds are collateralized by an irrevocable letter of
credit which has been issued by Development Bank of Singapore, New York Branch,
in the amount of $11,107,356.60 deposited with the Trustee. The amount of the
letter of credit includes $10,989,487.55 for the purchase of $11,455,000 face
amount of the bonds, plus $117,869.05 for accrued interest.
(2) Representing a special distribution to the Sponsors by the Trustee of an
amount equal to the accrued interest on the bonds.
(3) A portion of the Unit Price consists of cash in an amount sufficient to
pay for costs incurred in establishing the Fund. These costs have been estimated
at $2.00 per 1,000 Units. A distribution will be made at the close of the
initial offering period to an account maintained by the Trustee from which the
organizational expense obligation of the investors to the Sponsors will be
satisfied. If the actual organization costs exceed the estimated aggregate
amount shown above, the Sponsors will pay for this excess amount.
(4) Assumes the maximum up-front sales fee per 1,000 units of 1.00% of the
Public Offering Price. A deferred sales fee of $19.00 per 1,000 units is payable
over a two-year period ($2.38 per 1,000 units quarterly in the first year and
$2.37 per 1,000 units quarterly in the second year). Distributions will be made
to an account maintained by the Trustee from which the deferred sales fee
obligation of the investors will be satisfied. If units are redeemed prior to
the end of second anniversary of the Fund, the remaining portion of the deferred
sales fee applicable to such units will be transferred to the account on the
redemption date.
(5) Aggregate Unit Price (exclusive of interest) computed on the basis of
the offer side evaluation of the underlying bonds as of the evaluation time on
the business day prior to the Initial Date of Deposit.
