RISK/RETURN SUMMARY

<TABLE>
<C> <S>
1. WHAT IS THE PORTFOLIO'S OBJECTIVE?
- The Portfolio seeks capital appreciation
by investing in a diversified portfolio
of global equity securities for
approximately one year.

You can participate in the Portfolio by
purchasing units. Each unit represents
an equal share of the stocks in the
Portfolio and receives an equal share of
dividend income.

2. WHAT IS THE PORTFOLIO'S INVESTMENT
STRATEGY?
- The Portfolio plans to invest in a
number of stocks favored by demographic
trends--companies which should
experience growth as the "baby boomer"
generation grows older. Our Portfolio
Consultants are Wall Street veterans
William Sterling and Stephen Waite,
authors of the book "Boomernomics," and
authorities on the trends of baby
boomers. Sterling and Waite, together
with their team of financial
professionals, selected the securities
for this Portfolio. They believe that in
the decade to come, economic
globalization and advances in
technology, coupled with the spending
and saving patterns of this demographic
group, are likely to have an important
impact on the healthcare, technology,
telecommunications, consumer products
and financial services industries, and
accordingly, have selected Portfolio
securities in these industries.
- The baby boomers, the generation born
between 1946 and 1964, have remarkably
consistent saving, spending and
life-style patterns. Past baby boomer
spending patterns appear to have a
direct correlation to the growth of
certain industries that meet the needs
of baby boomers.
- The Sponsors believe that as the baby
boomers and their children mature and
adjust their lives for later years,
spending patterns are likely to have a
positive effect on the industries
represented in the Portfolio.

- We plan to hold the stocks in the
Portfolio for about one year. At the end
of the year, we will liquidate the
Portfolio and intend to apply the same
Strategy to select a new portfolio, if
available.

- Each Baby Boom Economy Portfolio is
designed to be part of a longer term
strategy. We believe that more
consistent results are likely if the
strategy is followed for at least three
to five years, but you are not required
to stay with the strategy or to roll
over your investment. You can sell your
units at any time.

3. WHAT COUNTRIES AND INDUSTRIES ARE
REPRESENTED IN THE PORTFOLIO?

<TABLE>
<C> <S>
- Because the Portfolio is concentrated in
technology stocks, adverse developments
in this industry may affect the value of
your units.

- This Portfolio contains a number of
foreign securities. Some of the risks of
holding foreign securities include:
-- political/economic developments;
-- withholding taxes;
-- exchange controls or local
restrictions on dividend payments;
-- currency risk;
-- less available public information; and
-- less liquidity.

- The Portfolio may continue to purchase or
hold the stocks originally selected even
though their market value may have
changed or they may be subject to sell
recommendations from one or more of the
Sponsors.

- Even if there are no changes in the
Portfolio securities from year to year,
you still must pay tax on any gain.

5. IS THIS PORTFOLIO APPROPRIATE FOR YOU?

- The Portfolio was designed to meet the
financial needs of investors who still
have a substantial number of years ahead
of them in the workforce, and therefore
can afford to take the risks that may
yield a better reward.

- The Portfolio can also represent a
portion of the equity investment in your
diversified Portfolio.
- The Portfolio is not appropriate for you
if you are not comfortable with the
Strategy or are unwilling to take the
risk involved with an equity investment.
It generally is not be appropriate for
you if you are seeking preservation of
capital or high current income.

6. WHAT ARE THE PORTFOLIO'S FEES AND
EXPENSES?
This table shows the costs and expenses
you may pay, directly or indirectly, when
you invest in the Portfolio.

The Creation and Development Fee

compensates the Sponsors for the creation
and development of the Portfolio and is
computed based on the Portfolio's average
daily net asset value through the date of
collection at the end of the primary
offering period which is generally 90
days. This fee historically had been
included in the sales fee.

EXAMPLE
This example may help you compare the
cost of investing in the Portfolio to the
cost of investing in other funds.
The example assumes that you invest
$10,000 in the Portfolio 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 Portfolio's
operating expenses stay the same.
Although your actual costs may be higher
or lower, based on these assumptions your
costs would be:

<TABLE>

7. IS THE PORTFOLIO MANAGED?
Unlike a mutual fund, the Portfolio is
not managed and stocks are not sold
because of market changes. The Sponsors
monitor the portfolio and may instruct
the Trustee to sell securities under
certain limited circumstances. However,
given the investment philosophy of the
Portfolio, the Sponsors are not likely to
do so.

8. HOW DO I BUY UNITS?

The minimum investment is $250.

You can buy units from the Sponsors and
other broker-dealers. 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 $999.91
(as of August 29, 2000)

Unit price is based on the net asset
value of the Portfolio plus the up-front
sales fee. Unit price also includes the
estimated organization costs shown on
page 4, to which no sales fee has been
applied.
The Portfolio stocks are valued by the
Trustee on the basis of their closing
prices at 4:00 p.m. Eastern time every
business day. Unit price changes every
day with changes in the prices of the
stocks.

9. HOW DO I SELL UNITS?

You may sell your units at any time to
the Sponsors 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 and the
costs of liquidating securities to meet
the redemption.
10. HOW ARE DISTRIBUTIONS MADE AND TAXED?

The Fund pays distributions of any
dividend income, net of expenses, on the
25th of July, 2001 if you own units on
the 10th of this month. For tax purposes,
you will be considered to have received
all the dividends paid on your pro rata
portion of each security in the Portfolio
when those dividends are received by the
Portfolio regardless of when you receive
distributions and regardless of whether
you reinvest your dividends in the
Portfolio. Dividends paid with respect to
any foreign securities in the Portfolio
will generally be subject to foreign
withhholding taxes. A portion of the
dividend payments may be used to pay
expenses of the Portfolio. If you are a
corporate investor, you may be eligible
for the dividends-received deduction with
respect to a portion of the dividends if
you satisfy the applicable holding period
and other requirements. Foreign
investors' shares of dividends will
generally be subject to withholding
taxes.

11. WHAT OTHER SERVICES ARE AVAILABLE?

REINVESTMENT
You may choose to reinvest your
distributions into additional units of
the Portfolio. Unless you choose
reinvestment, you will receive your
distributions in cash.

EXCHANGE PRIVILEGES
You may exchange units of this Portfolio
for units of certain other Defined Asset
Funds. You may also exchange into this
Portfolio from certain other funds. We
charge a reduced sales fee on exchanges.

- a notice from the Trustee if new equity securities are deposited in exchange
or substitution for equity securities originally deposited;
- a final report on Portfolio activity; and
- annual tax information. THIS WILL ALSO BE SENT TO THE IRS. YOU MUST REPORT THE
AMOUNT OF INCOME RECEIVED DURING THE YEAR. PLEASE CONTACT YOUR TAX ADVISOR IN
THIS REGARD.

You may request audited financial statements of the Portfolio from the Trustee.

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

THE RISKS YOU FACE

CONCENTRATION RISK

When stocks in a particular industry make up 25% or more of the Portfolio, it is
said to be "concentrated" in that industry, which makes the Portfolio less
diversified.

Here is what you should know about the Portfolio's concentration in technology
stocks. Technology stocks tend to be relatively volatile as compared to other
types of investments. These kinds of companies:

- are rapidly developing and highly competitive, both domestically and
internationally;

- may be smaller and less seasoned companies with limited product lines, markets
or financial resources and limited management or marketing personnel; and

- are affected by:

-- worldwide scientific and technological developments (and resulting
product obsolescence);

-- government regulations;

-- increase in material or labor costs;

-- changes in distribution channels; and

-- the need to manage inventory levels in line with product demand.

Other risk factors include:

- short product life cycles;

- aggressive pricing and reduced profit margins;

- dramatic and often unpredictable changes in growth rates;

- frequent new product introduction and the need to enhance existing products;
and

- intense competition from large established companies and potential competition
from small start up companies.

Technology companies are also dependent to a substantial degree upon skilled
professional and technical personnel and there is considerable competition for
the services of qualified personnel in the industry.

FOREIGN ISSUER RISK

Investments in securities of foreign issuers involve risks that are different
from investments in securities of domestic issuers. They may include:
- political and economic developments;
- possibility of withholding taxes;

6
<PAGE>
- exchange controls or other governmental restrictions on the payment of
dividends;
- less publicly available information; and
- absence of uniform accounting, auditing and financial reporting standards,
practices and requirements.

AMERICAN DEPOSITARY SHARES AND RECEIPTS

American depositary shares and receipts are issued by an American bank or trust
company to evidence ownership of underlying common stock issued by a foreign
corporation and deposited in a depositary facility. The terms and conditions of
the depositary facility may result in less liquidity or lower market prices for
the ADRs than for the underlying shares. Certain of the Portfolio Securities
were purchased in ADR form in the United States.

FOREIGN CURRENCY RISK

Because securities of non-U.S. issuers generally pay dividends and trade in
foreign currencies, there is the risk that the U.S. dollar value of these
securities will vary with fluctuations in foreign exchange rates.

At the present time the Sponsors do not believe that any of the Portfolio
Securities is subject to exchange control restrictions which would materially
interfere with payment to the Portfolio of amounts due on the Portfolio
Securities. The adoption of exchange control regulations or other legal
restrictions could have an adverse impact on the marketability of international
securities in the Portfolio and on the ability of the Portfolio to satisfy
redemptions. There can be no assurance that exchange control regulations might
not be adopted in the future that would adversely affect payments to the
Portfolio.

LIQUIDITY

Sales of foreign securities in United States securities markets are ordinarily
subject to severe restrictions and will generally be made only in foreign
securities markets. You should know that:
- securities may be traded in foreign countries where the securities markets
are not as developed or efficient and may not be as liquid as those in the
United States;
- a foreign market's liquidity might become impaired as a result of economic
or political turmoil, or if relations between the United States and such
foreign country deteriorate markedly; and
- the principal trading market for the Portfolio Securities, even if otherwise
listed, may be the over-the-counter market in which liquidity will depend on
whether dealers will make a market in the Portfolio Securities.

LITIGATION AND LEGISLATION RISKS

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

Future tax legislation could affect the value of the Portfolio by:
- reducing the dividends-received deduction; or
- increasing the corporate tax rate resulting in less money available for
dividend payments.

SELLING OR EXCHANGING UNITS

You can sell your units at any time for a price based on their net asset value.
Your net asset value is calculated each business day by:

7
<PAGE>
- ADDING the value of the Portfolio Securities, cash and any other Portfolio
assets;
- SUBTRACTING accrued but unpaid Portfolio expenses, unreimbursed Trustee
advances, cash held to buy back units or for distribution to investors, and
any other Portfolio 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.

As of the close of the initial offering period, the price you receive will be
reduced to pay the Portfolio's estimated organization costs.

If you sell your units before the final deferred sales fee installment, the
amount of any remaining payments 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
less any remaining deferred sales fee and the cost of liquidating Securities to
meet the redemption. We may resell the units to other buyers or to the Trustee.

We have maintained a secondary market continuously for more than 28 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 contacting your broker, dealer or financial
institution that holds your units in street name. 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 if it
believes it can obtain a higher price. In that case, you will receive the net
proceeds of the sale.

If the Portfolio does not have cash available to pay you for the units you are
selling, the Sponsors will select securities to be sold. These sales could be
made at times when the securities would not otherwise be sold and may result in
your receiving less than you paid for your unit and also reduce the size and
diversity of the Portfolio.

If you sell units with a value of at least $1,250,000 you may choose to receive
your distribution "in kind." If you so choose, you will receive securities and
cash with a total value equal to the price of your units. The Trustee will try
to distribute securities in the portfolio pro rata, but it reserves the right to
distribute only one or a few securities. The Trustee will act as your agent in
an in-kind distribution and will either hold the securities for your account or
transfer them as you instruct. You must pay any transaction costs as well as
transfer and ongoing custodial fees on sales of securities distributed in-kind.

There could be a delay in paying you for your units:

8
<PAGE>
- 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
securities not reasonably practicable; and
- for any other period permitted by SEC order.

ROLLOVER/EXCHANGE OPTION

When the portfolio is about to terminate, you may have the option to roll your
proceeds into the next Baby Boom Economy Growth Portfolio if one is available.

If you hold your Units with the Sponsors and notify your financial adviser by
September 25, 2001, your units will be redeemed and certain distributed
securities plus the proceeds from the sale of the remaining distributed
securities will be reinvested in units of a new Baby Boom Economy Growth
Portfolio. If you decide not to roll over your proceeds, you will receive a cash
distribution (or, if you so choose, an in-kind distribution) after the Portfolio
terminates.

If you do not elect the rollover option by the above notification date, but
later inform your financial professional that you want to invest in the next
Baby Boom Economy Growth Portfolio, you will recognize gain, if any, with
respect to your pro rata share of each security in this Portfolio. You will not
be entitled to claim a loss in respect of any security to the extent that the
same security is included in your pro rata share of the next Baby Boom Economy
Growth Portfolio.

The Portfolio will terminate by October 30, 2001. However, the Sponsors may
extend the termination date for a period no longer than 30 days without notice
to Unit holders. You may, by written notice to the Trustee at least ten business
days prior to termination, elect to receive an in-kind distribution of your pro
rata share of the Securities remaining in the Portfolio at that time (net of
your share of expenses). Of course, you can sell your Units at any time prior to
termination.

If you continue to hold your Units, you may exchange units of this Portfolio any
time before this Portfolio terminates for units of certain other Defined Asset
Funds at a reduced sales fee. In addition, you may exchange into this Fund from
certain other Defined Asset Funds and unit trusts. To exchange units, you should
talk to your financial professional about what Portfolios are exchangeable,
suitable and currently available.

We may amend or terminate the options to exchange your units or roll your
proceeds at any time without notice.

HOW THE FUND WORKS

PRICING

Units are charged a combination of initial and deferred sales fees.

In addition, during the initial offering period, a portion of the price of a
unit also consists of securities to pay all or some of the costs of organizing
the Portfolio including:
- cost of initial preparation of legal documents;
- federal and state registration fees;
- initial fees and expenses of the Trustee;
- initial audit; and

9
<PAGE>
- legal expenses and other out-of-pocket expenses.

The estimated organization costs will be deducted from the assets of the
Portfolio as of the close of the initial offering period.

The deferred sales fee is generally a monthly charge of $2.50 per 1,000 units
and is accrued in six installments. Units redeemed or repurchased prior to the
accrual of the final deferred sales fee installment will have the amount of any
remaining installments deducted from the redemption or repurchase proceeds or
deducted in calculating an in-kind distribution, however, this deduction will be
waived in the event of the death or disability (as defined in the Internal
Revenue Code of 1986) of an investor. The initial sales fee is equal to the
aggregate sales fee less the aggregate amount of any remaining installments of
the deferred sales fee.

It is anticipated that securities will not be sold to pay the deferred sales fee
until after the date of the last installment. Investors will be at risk for
market price fluctuations in the securities from the several installment accrual
dates to the dates of the actual sale of securities to satisfy this liability.

EVALUATIONS

The Trustee values the securities on each business day (i.e., any day other than
Saturdays, Sundays and the following holidays as observed by the New York Stock
Exchange: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas).
If the securities are listed on a national securities exchange or the Nasdaq
National Market, evaluations are generally based on closing sales prices on that
exchange or that system or, if closing sales prices are not available, at the
mean between the closing bid and offer prices.

INCOME
- The annual income per unit, after deducting estimated annual Portfolio
expenses per unit, will depend primarily upon the amount of dividends declared
and paid by the issuers of the securities and changes in the expenses of the
Portfolio and, to a lesser degree, upon the level of purchases of additional
securities and sales of securities. There is no assurance that dividends on
the securities will continue at their current levels or be declared at all.
- Each unit receives an equal share of distributions of dividend income net of
estimated expenses. Because dividends on the securities are not received at a
constant rate throughout the year, any distribution may be more or less than
the amount then credited to the income account. The Trustee credits dividends
received 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 a fee monthly. It also benefits when it holds cash for the
Portfolio in non-interest bearing accounts. The Trustee may also receive
additional amounts:
- expenses for keeping the Portfolio's registration statement current;

10
<PAGE>
- Portfolio termination expenses and any governmental charges.
- for extraordinary services and costs of indemnifying the Trustee and the
Sponsors; and
- costs of actions taken to protect the Portfolio and other legal fees and
expenses;

The Sponsors are currently reimbursed up to 70 CENTS per 1,000 units annually
for providing portfolio supervisory, bookkeeping and administrative services and
for any other expenses properly chargeable to the Portfolio. While this fee may
exceed the amount of these costs and expenses attributable to this Portfolio,
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 Sponsors.

The Sponsors will receive a Creation and Development Fee of .25% of the
Portfolio's average daily net asset value through the date of collection. This
fee, which has historically been included in the gross sales fee, compensates
the Sponsors for the creation and development of the Portfolio's objective and
policies and portfolio composition and size, selection of service providers and
information services. No portion of the Creation and Development Fee is applied
to the payment of distribution expenses or as compensation for sales efforts.

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

The maximum sales fee is 2.50%. If you hold units in certain eligible accounts
offered by the Sponsor, you will pay no sales fee. Employees and non-employee
directors of the Sponsor may be charged a reduced sales fee of no less than
$5.00 per 1,000 Units. If your aggregate sales fee is less than the deferred
sales fee, you will be given additional units which will decrease the effective
maximum sales fee to the amount shown below.

The maximum sales fee is effectively reduced if you invest as follows:

<TABLE>
<CAPTION>
YOUR MAXIMUM SALES
IF YOU INVEST: FEE WILL BE:
-------------- ------------------
<S> <C>
Less than $50,000 2.50%
$50,000 to $99,999 2.25%
$100,000 to $249,999 1.75%
$250,000 to $999,999 1.50%
$1,000,000 or more 0.75%
</TABLE>

The deferred sales fees you owe are paid from the Capital Account. Although we
may collect the deferred sales charge monthly, to keep Units more fully invested
we do not currently plan to pay the deferred sales charge until after the
rollover notification date.

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

PORTFOLIO CHANGES

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.

We decide whether to offer for sale units that we acquire in the secondary
market after reviewing:
- diversity of the Portfolio;

11
<PAGE>
- size of the Portfolio relative to its original size;
- ratio of Portfolio expenses to income; and
- cost of maintaining a current prospectus.

If the Portfolio is buying or selling a stock actively traded on a national
securities exchange or certain foreign exchanges, it may buy from or sell to
another Defined Asset Fund at the stock's closing sale price (without any
brokerage commissions).

PORTFOLIO TERMINATION

When the Portfolio is about to terminate you will receive a notice, and you will
be unable to sell your units after that time. Unless you choose to receive an
in-kind distribution of securities, we will sell any remaining securities, and
you will receive your final distribution in cash.

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

NO CERTIFICATES

All investors are required to hold their Units in uncertificated form and in
"street name" by their broker, dealer or financial institution at the Depository
Trust Company.

TRUST INDENTURE

The Portfolio is a "unit investment trust" governed by a Trust Indenture, a
contract between the Sponsors and the Trustee, 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 Sponsor).

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 Portfolio 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;
- it becomes incapable of acting or bankrupt or its affairs are taken over by
public authorities; or
- the Sponsors determine that its replacement is in your best interest.

Investors holding 51% of the units may remove the Trustee. The Trustee may
resign or be removed by the Sponsors without the consent of investors. The
resignation or removal of the Trustee 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 may petition a court to appoint a successor.

If the Sponsors fail to perform their duties or become bankrupt the Trustee may:

12
<PAGE>
- remove them and appoint replacement Sponsors;
- liquidate the Portfolio; or
- continue to act as Trustee without the Sponsors.

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

LEGAL OPINION

Davis Polk & Wardwell, 450 Lexington Avenue, New York, New York 10017, as
special counsel for the Sponsors, has given an opinion that the units are
validly issued.

AUDITORS

Deloitte & Touche LLP, 2 World Financial Center, New York, New York 10281,
independent accountants, audited the Statement 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

PAINEWEBBER INCORPORATED (a wholly-owned subsidiary of PaineWebber Group Inc.)

DEAN WITTER REYNOLDS INC. (a principal operating subsidiary of Morgan Stanley
Dean Witter & Co.)
Two World Trade Center--59th Floor,
New York, NY 10048

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 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

The Underwriter receives sales charges when it sells units. The Sponsors also
realize a profit or loss on deposit of the securities shown under Defined
Portfolio. 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.

The Sponsors or Underwriter may realize profits or sustain losses on stocks in
the Portfolio which were acquired from underwriting syndicates of which they
were a member.

13
<PAGE>
policies and portfolio composition and size, selection of service providers and
information services. No portion of the Creation and Development Fee is applied
to the payment of distribution expenses or as compensation for sales efforts.

During the initial offering period, the Sponsors also may realize profits or
sustain losses on units they hold due to fluctuations in the price per unit. The
Sponsors experienced a loss of $1,074.02 on the initial deposit of the
securities. Any profit or loss to the Portfolio will be effected by the receipt
of applicable sales charges and a gain or loss on subsequent deposits of
securities. 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.

Dealers will be entitled to the concession stated below on Units sold or
redeemed.

<TABLE>

</TABLE>

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

Each of the Portfolio and the Agent for the Sponsors have adopted a code of
ethics requiring preclearance and reporting of personal securities transactions
by its employees with access to information on portfolio transactions. Subject
to certain conditions, the codes permit employees to invest in Portfolio
securities for their own accounts. The codes are designed to prevent fraud,
deception and misconduct against the Portfolio 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 securities contained in the Portfolio. We
cannot predict whether any impact will be material to the Portfolio as a whole.

ADVERTISING AND SALES MATERIAL

Sales material may discuss developing a long-term financial plan, working with
your financial professional; the nature and risks of various investment
strategies and Defined Asset Funds that could help you toward your financial
goals and the importance of discipline; how securities are selected for

14
<PAGE>
these funds, how the funds are created and operated, features such as
convenience and costs, and options available for certain types of funds
including automatic reinvestment, rollover, exchanges and redemption. It may
also summarize some similarities and differences with mutual funds and discuss
the philosophy of spending time in the market rather than trying to time the
market, including probabilities of negative returns over various holding
periods.

Advertising and sales literature may contain past performance of the Portfolio
either in dollars or average annualized or cumulative returns (changes in market
prices with dividends reinvested) for various periods, compared to the Standard
& Poor's 500 Index or other relevant market indices. Returns reflect deduction
of actual Portfolio expenses and sales charges.

While indexing attempts to mirror market trends, the Portfolio's screening
process selects stocks from a major index for a combination of value, capital
appreciation potential and current dividend income. Because of this disciplined
screening process, investors are relieved of making individual buy and sell
decisions.

Sales literature and articles may state research opinions on the economy and
industry sectors and include a list of funds generally appropriate for pursuing
these recommendations.

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.

In the opinion of our counsel, under existing law:

GENERAL TREATMENT OF THE FUND AND YOUR INVESTMENT

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

You will be considered to receive your share of any dividends paid when those
dividends are received by the Portfolio. Income from dividends will be taxed at
ordinary income rates. If you are a corporate investor, you may be eligible for
the dividends-received deduction with respect to a portion of the dividends if
you satisfy the applicable holding period and other requirements. You should
consult your tax adviser in this regard.

GAIN OR LOSS UPON DISPOSITION

You will generally recognize gain or loss when you dispose of your units for
cash (by sale or redemption), when you exchange your units for units of another
Defined Asset Fund, or when the Trustee disposes of the securities in the
Portfolio. You generally will not recognize gain or loss on an "in-kind"
distribution to you of your proportional share of the Portfolio securities. Your
holding period for the distributed Securities will include your holding period
in your units.

If you do not hold your Portfolio in a currently non-taxable account (e.g., an
IRA account), you may elect to roll over your investment in the Portfolio. If
you so elect by September 25, 2001, you will recognize

15
<PAGE>

gain or loss only with respect to your share of those securities that are not
rolled over into the new portfolio. You will not recognize gain or loss with
respect to your share of those securities that are rolled over and your basis in
those securities will remain the same as before the rollover.

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 or loss from the Portfolio will be long-term if you are considered
to have held your investment which produces the gain or loss for more than one
year and short-term otherwise. Because the deductibility of capital losses is
subject to limitations, you may not be able to deduct all of your capital
losses. You should consult your tax adviser in this regard.

YOUR TAX BASIS IN THE SECURITIES

Your aggregate tax basis in units that you have purchased for cash will be equal
to the cost of the units, including the sales fee.

Your aggregate tax basis in units that you hold as a result of a rollover from
an earlier protfolio will equal your basis in the Securities that were rolled
over from the previous portfolio plus the proceeds from the sale of Securities
from the portfolio that were not rolled over (other than proceeds that were paid
to you). You should not increase your basis in your units by deferred sales
charges, organizational expenses, or by any portion of the Creation and
Development Fee. The tax reporting form and annual statements you receive will
be based on the net amounts paid to you, from which these expenses will already
have been deducted. Your basis for Securities distributed to you will be the
same as the portion of your basis in your units that is attributable to the
distributed Securities, and your holding period for the distributed Securities
will include your holding period in your units.

EXPENSES

If you are an individual who itemizes deductions, you may deduct your share of
Portfolio expenses (including the applicable portion of the Creation and
Development Fee), but only to the extent that your share of the expenses,
together with your other miscellaneous deductions, exceeds 2% of your adjusted
gross income. Your ability to deduct Portfolio expenses will be limited further
if your adjusted gross income exceeds a specified amount, currently $128,950
($64,475 for a married person filing separately).

STATE AND LOCAL TAXES

Under the income tax laws of the State and City of New York, the Portfolio will
not be taxed as a corporation, and the income of the Portfolio will be treated
as the income of the investors in the same manner as for federal income tax
purposes.

16
<PAGE>
FOREIGN INVESTORS

If you are a foreign investor and you are not engaged in a U.S. trade or
business, you generally will be subject to withholding tax at a rate of 30% (or
a lower applicable treaty rate) on your share of dividends received by the
Portfolio. You should consult your tax adviser about the possible application of
federal, state and local, and foreign taxes.

FOREIGN TAXES

Dividends paid with respect to any foreign Securities in the Portfolio will
generally be subject to foreign withholding taxes. You will be considered to
receive the entire amount of your share of these dividends, including your share
of foreign taxes withheld. You may be eligible for a credit or a deduction for
your share of these taxes to reduce your U.S. tax liability, subject to various
requirements and limitations. You should consult your tax adviser in this
regard.

RETIREMENT PLANS

You may wish to purchase units for an Individual Retirement Account ("IRAs") or
other retirement plan. Generally, capital gains and income received in each of
these plans are exempt from federal taxation. All distributions from these types
of plans are generally treated as ordinary income but may, in some cases, be
eligible for tax-deferred rollover treatment. You should consult your attorney
or tax adviser about the specific tax rules relating to these plans. These plans
are offered by brokerage firms, including the Sponsors of this Portfolio, and
other financial institutions. Fees and charges with respect to such plans may
vary.

SUPPLEMENTAL INFORMATION

You can receive at no cost supplemental information about the Portfolio by
calling the Trustee. The supplemental information includes more detailed risk
disclosure and general information about the structure and operation of the
Portfolio. The supplemental information is also available from the SEC.

(1) Aggregate cost to the Portfolio of the securities listed under
Defined Portfolio determined by the Trustee at 4:00 p.m., Eastern time on August
29, 2000. The contracts to purchase securities are collateralized by an
irrevocable letter of credit which has been issued by San Paolo Bank, New York
Branch, in the amount of $1,096,664.59 and deposited with the Trustee. The
amount of the letter of credit includes $1,095,590.57 for the purchase of
securities.

(2) A portion of the Unit Price consists of securities in an amount
sufficient to pay all or a portion of the costs incurred in establishing the
Portfolio. These costs have been estimated at $0.88 per 1,000 Units. A
distribution will be made as of the close of the initial offering period to an
account maintained by the Trustee from which the organization expense obligation
of the investors will be satisfied. If actual organization costs exceed the
estimated amount shown above, the Sponsors will pay this excess amount.

(3) Because the value of securities at the evaluation time on the
Initial Date of Deposit may differ from the amounts shown in this statement of
condition, the number of Units offered on the Initial Date of Deposit will be
adjusted to maintain the $999.91 per 1,000 Units offering price only for that
day. The Unit Price on any subsequent business day will vary.

(4) Aggregate public offering price computed on the basis of the value
of the underlying securities at 4:00 p.m., Eastern time on August 29, 2000.

(5) Assumes the maximum initial sales charge per 1,000 units of 1.00% of
the Unit Price. A deferred sales charge of $2.50 per 1,000 Units is payable on
February 1, 2001 and the 1st day of each month thereafter through July 1, 2001.
Distributions will be made to an account maintained by the Trustee from which
the deferred sales charge obligation of the investors to the Sponsors will be
satisfied. If units are redeemed prior to July 1, 2001, the remaining portion of
the distribution applicable to such units will be transferred to such account on
the redemption date.
