CALIFORNIA INSURED PORTFOLIO--RISK/RETURN SUMMARY

<TABLE>
<C> <S>
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?

- The Fund plans to hold to maturity 7
long-term tax-exempt municipal bonds,
and some short-term bonds reserved to
pay the deferred sales fee, with an
aggregate face amount of $4,825,000.
- The Fund is a unit investment trust
which means that, unlike a mutual fund,
the Portfolio is not managed.
- The bonds are rated AAA or Aaa by
Standard & Poor's, Moody's or Fitch.
- 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.
- 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:
</TABLE>

<TABLE>
/ / General Obligation 1%
<S> <C>
/ / Hospitals/Health Care 25%
/ / Municipal Water/Sewer
Utilities 10%
/ / Special Tax 32%
/ / Electric Utilities 16%
/ / Universities/Colleges 16%
</TABLE>

<TABLE>
<C> <S>
4. WHAT ARE THE SIGNIFICANT RISKS?

YOU CAN LOSE MONEY BY INVESTING IN THE
FUND. THIS CAN HAPPEN FOR VARIOUS
REASONS, INCLUDING:

- Rising interest rates, an issuer's
worsening financial condition or a drop
in bond ratings can reduce the price of
your units.

- Because the Fund is concentrated in
hospital/health care and special tax
bonds, adverse developments in these
sectors may affect the value of your
units.

- 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.

- 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 CALIFORNIA SO IT IS LESS
DIVERSIFIED THAN A NATIONAL FUND AND IS
SUBJECT TO RISKS PARTICULAR TO CALIFORNIA
WHICH ARE BRIEFLY DESCRIBED UNDER STATE
CONCENTRATION RISKS LATER IN THIS
PROSPECTUS.
</TABLE>

<PAGE>

<TABLE>
<C> <S>
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.

8. IS THE FUND MANAGED?

Unlike a mutual fund, the Fund is not managed

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.
</TABLE>

<PAGE>

<TABLE>
<C> <S>
9. HOW DO I BUY UNITS?

The minimum investment is $250.00.

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 $884.35
(as of December 31, 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, less any
remaining deferred sales fee. You will
not pay any other fee when you sell
your units.
</TABLE>

<TABLE>
<C> <S>
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 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

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 2000
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.

12
<PAGE>
WHAT YOU CAN EXPECT FROM YOUR INVESTMENT

INCOME TWICE A YEAR

The Fund will pay you regular semi-annual income. Your income may vary because
of:
- elimination of one or more bonds from the Fund's portfolio because of calls,
redemptions or sales;
- a change in the Fund's expenses; or
- 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):

<TABLE>
<S> <C> <C>
Estimated Annual Estimated
Interest Income - Annual Expenses
- -------------------------------------
Unit Price
</TABLE>

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:
- - a statement of income payments and any principal payments;
- - a notice from the Trustee when new bonds are deposited in exchange or
substitution for bonds originally deposited;
- - an annual report on Fund activity; and
- - 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:
- - copies of bond evaluations to enable you to comply with federal and state tax
reporting requirements; and
- - 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:
- it no longer needs the money for the original purpose;
- the project is condemned or sold;
- the project is destroyed and insurance proceeds are used to redeem the
bonds;
- any related credit support expires and is not replaced; or
- 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 California and New Jersey Portfolios'
concentrations in hospital and health care bonds.
- 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;
- hospitals face increasing competition resulting from hospital mergers and
affiliations;
- hospitals need to reduce costs as HMOs increase market penetration and
hospital supply and drug companies raise prices;
- hospitals and health care providers are subject to various legal claims by
patients

14
<PAGE>
and others and are adversely affected by increasing costs of insurance; and
- 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;
- 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
- 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 California Portfolio's concentration in
special tax bonds. Special tax bonds are payable from and secured by the
revenues a municipality derives from a particular tax; for example, a tax on
hotel rentals, on the purchase of food and beverages, car rentals, or liquor
consumption. These bonds are not secured by general tax revenues. Payment on
these bonds may be adversely affected by:
- a reduction in revenues resulting from a decline in the local economy or
population; or
- a decline in the consumption, use or cost of the goods and services that are
subject to taxation.

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

STATE CONCENTRATION RISK

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.

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

- Since that time the California economy has improved markedly and the extreme
budgetary pressures have begun to lessen.

STATE GOVERNMENT

The 1999-2000 Budget Act allocated a State budget of approximately $63.7 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:

- 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 remains unknown.

- 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.

- California's general obligation bonds are currently rated AA3 by Moody's and
AA- by Standard & Poor's.

OTHER RISKS

Issuers' ability to make payments on bonds (and the remedies available to
bondholders)

15
<PAGE>
could also be adversely affected by the following constraints:

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

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

- 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.

NEW JERSEY RISKS

STATE AND LOCAL GOVERNMENT

Certain features of New Jersey law could affect the repayment of debt:

- the State of New Jersey and its agencies and public authorities issue
general obligation bonds, which are secured by the full faith and credit of
the state, backed by its taxing authority, without recourse to specific
sources of revenue, therefore, any liability to increase taxes could impair
the state's ability to repay debt; and

- the state is required by law to maintain a balanced budget, and state
spending for any given municipality or county cannot increase by more than
5% per year. This limit could make it harder for any particular county or
municipality to repay its debts.

In recent years the state budget's main expenditures have been

- elementary and secondary education, and

- state agencies and programs, including police and corrections facilities,
higher education, and environmental protection.

The state's general obligations are rated Aa1 by Moody's and AA+ by Standard &
Poor's.

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:

- the high combined state and local tax burden;

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

- sensitivity to the financial services industry; and

- 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.

16
<PAGE>
NEW YORK CITY GOVERNMENT

Even though the City had budget surpluses each year from 1981, budget gaps of
nearly $2 billion are projected for the 2001, 2002, and 2003 fiscal years. New
York City faces fiscal pressures from:

- aging public facilities that need repair or replacement;

- welfare and medical costs;

- expiring labor contracts; and

- 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. $31.2 billion of combined City, MAC and PBC
debt is outstanding, and the City proposes $25.3 billion of financing over
fiscal 1999-2003.

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

The bonds are backed by insurance companies (as shown under 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 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:
- limiting real property taxes,
- reducing tax rates,
- imposing a flat or other form of tax, or
- 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:
- ADDING the value of the bonds, net accrued interest, cash and any other Fund
assets;
- 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
- 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.

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

17
<PAGE>
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 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:
- if the New York Stock Exchange is closed (other than customary weekend and
holiday closings);
- 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
- for any other period permitted by SEC order.

18
<PAGE>
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.

In addition, as with mutual funds, the Fund (and therefore the investors) pay
all or some of the costs of organizing the Fund including:
- cost of initial preparation of legal documents;
- federal and state registration fees;
- initial fees and expenses of the Trustee;
- initial audit; and
- 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

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:

19
<PAGE>
- to reimburse the Trustee for the Fund's operating expenses;
- for extraordinary services and costs of indemnifying the Trustee and the
Sponsors;
- costs of actions taken to protect the Fund and other legal fees and
expenses;
- expenses for keeping the Fund's registration statement current; and
- 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.

Any 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.

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 may affect the
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:
- diversity of the portfolio;
- size of the Fund relative to its original size;
- ratio of Fund expenses to income;
- current and long-term returns;
- degree to which units may be selling at a premium over par; and
- cost of maintaining a current prospectus.

20
<PAGE>
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:
- to cure ambiguities;
- to correct or supplement any defective or inconsistent provision;
- to make any amendment required by any governmental agency; or
- 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:
- it fails to perform its duties and the Sponsors determine that its
replacement is in your best interest; or
- 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

21
<PAGE>
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:
- remove it and appoint a replacement Sponsor;
- liquidate the Fund; or
- 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 are:
MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED (a wholly-owned subsidiary of
Merrill Lynch & Co., Inc.)
P.O. Box 9051,
Princeton, NJ 08543-9051
SALOMON SMITH BARNEY INC. (an indirectly wholly-owned subsidiary of Citigroup
Inc.)

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 Governors of the Federal
Reserve System and New York State banking authorities.

22
<PAGE>
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

The Fund and the Agent for the Sponsors have each adopted a code of ethics
requiring reporting of personal securities transactions by its employees with
access to information on Fund transactions. Subject to certain conditions, the
codes permit employees to invest in Fund securities for their own accounts. The
codes are designed to prevent fraud, deception and misconduct against the Fund
and to provide reasonable standards of conduct. These codes are on file with the
Commission and you may obtain a copy by contacting the Commission at the address
listed on the back cover of this prospectus.

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"). To date we are not aware of any major operational difficulties
resulting from the computer system changes necessary to prepare for the Year
2000. However, there can be no assurance that the Year 2000 Problem will not
adversely affect the issuers of the bonds contained in a Portfolio. We cannot
predict whether any impact will be material to the Fund 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 or subject to
special rules. 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 may be taken
into account in determining your preference items for alternative minimum tax
purposes. Neither we nor our counsel have reviewed the

23
<PAGE>
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, 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
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.

24
<PAGE>
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.

NEW JERSEY TAXES

In the opinion of Drinker Biddle & Reath LLP, Philadelphia, Pennsylvania,
special counsel on New Jersey tax matters:

The Fund will not be taxed as a corporation under the current income tax laws of
the State of New Jersey. Your income from the Fund may be subject to taxation
depending on where you live. If you are a New Jersey taxpayer your income from
the Fund (including gains on sales of bonds by the Fund) and gains on sales of
units by you will be tax-exempt to the extent that income and gains are earned
on bonds that are tax-exempt for New Jersey purposes. You should consult your
tax adviser as to the consequences to you with respect to any investment you
make in the Fund.

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 -
405 (California Insured, New Jersey Insured and New York

Defined Asset Funds:

We have audited the accompanying statements of condition of Municipal
Investment Trust Fund, Multistate Series - 405 (California Insured,
New Jersey Insured and New York Insured Trusts), Defined Asset Funds,
including the portfolios, as of December 31, 1999 and the related
statements of operations and of changes in net assets for the period
January 15, 1999 to December 31, 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 audit
to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the
financial statements. Securities owned at December 31, 1999, as shown
in such portfolios, were confirmed to us by The Chase Manhattan Bank,
the Trustee. An audit also includes assessing the accounting
principles used and significant estimates made by the Trustee, as well
as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Municipal
Investment Trust Fund, Multistate Series - 405 (California Insured,
New Jersey Insured and New York Insured Trusts), Defined Asset Funds
at December 31, 1999 and the results of their operations and changes
in their net assets for the above-stated period in conformity with
generally accepted accounting principle.

The Fund is registered under the Investment Company Act of 1940 as a
Unit Investment Trust. The following is a summary of significant
accounting policies consistently followed by the Fund in the
preparation of its financial statements. The policies are in
conformity with generally accepted accounting principles.

(A) Securities are stated at value as determined by the
Evaluator based on bid side evaluations for the securities,
except that value on January 15, 1999 was based upon
offering side evaluations at January 13, 1999, the day prior

1999 was also based on such offering side evaluations.

(B) The Fund is not subject to income taxes. Accordingly, no
provision for such taxes is required.

MULTISTATE SERIES - 405 (CALIFORNIA INSURED, NEW JERSEY
INSURED AND NEW YORK INSURED TRUSTS),
DEFINED ASSET FUNDS

NOTES TO PORTFOLIOS
As of December 31, 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 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).

(5) These bonds have been segregated to fund the deferred sales charges.
