Adding Growth Portfolio--Risk/Return Summary

1. What is the Portfolio's Objective?
The Portfolio seeks total return through both capital
appreciation and current income by investing in a
diversified portfolio of global equity securities for
approximately one year. The Portfolio will hold stocks in
the following industries: healthcare, technology,
entertainment, leisure and financial services.

2. What is the Portfolio's Investment Strategy?
o The Portfolio plans to invest in a number of stocks favored
by demographic trends-- industries and companies which
should do well as the 'baby boomer' generation grows older.
o 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.
o The Sponsors believe that as the baby boomers mature and
adjust their lives for later years, spending patterns are
likely to have a positive effect on the industries
represented in the Portfolio.
3. What industries are represented in the Portfolio?
Based upon the principal business of each issuer and
current market values, the Portfolio represents the
following industries:

Approximate
Portfolio
Percentage

o %
o %
o %
o %
o %
o %

4. What are the Significant Risks?
You can lose money by investing in the Portfolio. This can
happen for various reasons, including:
o Stock prices can be volatile. Market factors may cause the
prices and dividend yields of the stocks to change. Dividend
rates on the stocks or share prices may decline during the
life of the Portfolio.
o Because the Portfolio is concentrated in stocks of the
industry, adverse developments in this
industry may affect the value of your units.
o The Portfolio may continue to purchase or hold the stocks
originally selected even though their market value or yield
may have changed or they may be subject to sell
recommendations from one or more of the Sponsors.
o 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?
o The Adding Growth Portfolio was designed to meet the
financial needs of investors under the age of 40. The
Sponsors believe that investors in this group 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.
o The Adding Growth Portfolio can also represent the equity
portion of an investor's diversified Portfolio.
o When it comes to investing, it's important to balance how
much risk you're willing to take with your investment
portfolio, with the reward that you want for the long-term.
One way to do this is to find the appropriate allocation of
stocks and bonds to provide the growth you want, with a risk
level that is comfortable for you.
o 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 may not be
appropriate for you if you are seeking preservation of
capital or high current income.

Accumulating Assets Portfolio--Risk/Return Summary

1. What is the Portfolio's Objective?
The Portfolio seeks total return through both capital
appreciation and current income by investing approximately
75% of its assets in a diversified portfolio of global
equity securities and approximately 25% of its assets in
fixed-income securities for approximately one year. The
equity portion of the Portfolio will hold stocks in the
following industries: healthcare, technology, entertainment,
leisure and financial services.
2. What is the Portfolio's Investment Strategy?
o The Portfolio plans to invest approximately 75% of its
assets in a number of stocks favored by demographic
trends--industries and companies which should do well as the
'baby boomer' generation grows older.
o 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.
o The Sponsors believe that as the baby boomers mature and
adjust their lives for later years, spending patterns are
likely to have a positive effect on the industries
represented in the Portfolio.
o The Portfolio will invest approximately 25% of its assets in
fixed-income securities consisting of U.S. Government
Treasury Securities with various maturities.
3. What industries are represented in the Portfolio?
Based upon the principal business of each
issuer and current market values, the portfolio represents
the following industries:

Approximate

o U.S. Government Treasury Securities 25%

4. What are the Significant Risks?
You can lose money by investing in the Portfolio. This can
happen for various reasons, including:
o Stock prices can be volatile. Market factors may cause the
prices and dividend yields of the stocks to change. Dividend
rates on the stocks or share prices may decline during the
life of the Portfolio.
o The asset allocation percentages of the Portfolio are
calculated as of the date of deposit. Asset allocation
percentages may vary on any subsequent day due to
fluctuations in the market value of the Portfolio
securities.
o Rising interest rates can reduce the value of your units.
o Because the Portfolio is concentrated in stocks, adverse
developments in this industry may affect the value of your
units.
o Even if there are no changes in the fixed income or equity
Securities in the Portfolio from year to year, you still
must pay taxes on any gain.
o The Portfolio may continue to purchase or hold the
securities originally selected even though their market
value or yield may have changed, or they may be subject to
sell recommendations from one or more of the Sponsors.
5. Is this Portfolio Appropriate for You?
o The Accumulating Assets Portfolio was designed to meet the
financial needs of investors between the ages of 40 and 60
years. The Sponsors believe investors in this group are
generally enjoying their prime earning years. While they
frequently can afford to invest most of their money, they
have less time in the workforce to recover assets in the
event of a loss in the stock market. They may want to take a
more moderate approach to stocks, and include bonds in their
portfolio to help offset their investment risk.
o When it comes to investing, it's important to balance how
much risk you're willing to take with your investment
portfolio, with the reward that you want for the long-term.
One way to do this is to find the appropriate allocation of
stocks and bonds to provide the growth you want, with a risk
level that is comfortable for you.

10. How are Distributions Made and Taxed?
The Portfolio pays distributions of any dividend income,
net of expenses, on the 25th of and
, 1999, if you own units on the 10th of those
months. Distributions of ordinary income will be dividends
for federal income tax purposes and may be eligible for
the dividends-received deduction for corporations.
Distributions to foreign investors 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. You will pay only the
deferred sales fee remaining at the time of reinvestment.
Unless you choose reinvestment, you will receive your
income 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.

Adding Income Portfolio--Risk/Return Summary

1. What is the Portfolio's Objective?
The Portfolio seeks total return through both capital
appreciation and current income by investing approximately
50% of its assets in a diversified portfolio of global
equity securities and approximately 50% of its assets in
fixed-income securities for approximately one year. The
equity portion of the Portfolio will hold stocks in the
following industries: healthcare, technology, entertainment,
leisure and financial services.
2. What is the Portfolio's Investment Strategy?
o The Portfolio plans to invest approximately 50% of its
assets in a number of stocks favored by demographic
trends--industries and companies which should do well as the
'baby boomer' generation grows older.
o 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.
o The Sponsors believe that as the baby boomers mature and
adjust their lives for later years, spending patterns are
likely to have a positive effect on the industries
represented in the Portfolio.
o The Portfolio will invest approximately 25% of its assets in
fixed-income securities consisting of U.S. Government
Treasury Securities with various maturities.
3. What industries are represented in the Portfolio?
Based upon the principal business of each
issuer and current market values, the portfolio represents
the following industries:

Approximate

o %
o %
o %
o %
o %
o U.S. Government Treasury Securities 25%

4. What are the Significant Risks?
You can lose money by investing in the Portfolio. This can
happen for various reasons, including:
o Stock prices can be volatile. Market factors may cause the
prices and dividend yields of the stocks to change. Dividend
rates on the stocks or share prices may decline during the
life of the Portfolio.
o The asset allocation percentages of the Portfolio are
calculated as of the date of deposit. Asset allocation
percentages may vary on any subsequent day due to
fluctuations in the market value of the Portfolio
securities.
o Rising interest rates can reduce the value of your units.
o Because the Portfolio is concentrated in stocks, adverse
developments in this industry may affect the value of your
units.
o The Portfolio may continue to purchase or hold the stocks
originally selected even though their market value or yield
may have changed or they may be subject to sell
recommendations from one or more of the Sponsors.
5. Is this Portfolio Appropriate for You?
o The Adding Income Portfolio was designed to meet the
financial needs of investors over the age of 60 years. The
Sponsors believe investors in this group are generally
looking toward retirement. While a conservative level of
growth is still important for these investors, they may want
to also reduce their risk and preserve their capital for the
years to come. An equity portfolio balanced with bonds can
offer a steady stream of current income and still provide
the growth they need.
o When it comes to investing, it's important to balance how
much risk you're willing to take with your investment
portfolio, with the reward that you want for the long-term.
One way to do this is to find the appropriate allocation of
stocks and bonds to provide the growth you want, with a risk
level that is comfortable for you.

7. Is the Portfolio Managed?
Unlike a mutual fund, the Portfolio is not managed and
securities are not sold because of market changes. Rather,
the Sponsors monitor the Portfolio. The Portfolio may sell
a bond if certain adverse credit or other conditions
exist. The Sponsors may instruct the Trustee to sell
stocks under certain limited circumstances. However, given
the investment philosophy of the Portfolio, the Sponsor is
not likely to do so.
8. How do I Buy Units?
The minimum investment is $ .
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. Employees of certain
Sponsors and Sponsor affiliates and non-employee directors
of certain of the Sponsors may purchase units at a reduced
sales fee.

What You Can Expect From Your Investment

Income

Each Portfolio will pay to you any income it has received two times during its
life. Because each Portfolio generally pays dividends as they are received,
individual income payments will fluctuate based upon the amount of dividends
declared and paid by each issuer. Other reasons your income may vary are:
o changes in a Portfolio because of additional securities purchases or sales;
o a change in the Portfolio's expenses;
o the amount of dividends declared and paid; or
o elimination of one or more securities from a Portfolio because of
redemptions or sales.

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

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

There can be no assurance that any dividends on equity securities will be
declared or paid.

Records and Reports

You will receive:
o a notice from the Trustee if new securities are deposited in exchange or
substitution for securities originally deposited;
o a statement of income payments two times a year;
o a final report on Portfolio activity; and
o annual tax information. This will also be sent to the IRS. You must report the
amount of income and interest received during the year. Please contact your
tax advisor in this regard.

You may request copies of securities evaluations to enable you to comply with
federal and state tax reporting requirements and 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

Interest Rate Risk on the Treasury Securities

Investing involves risks, including the risk that your investment will decline
in value if interest rates rise. Generally, fixed income securities with longer
maturities will change in value more than those with shorter maturities. This
would result in early returns of principal to you and may result in early
termination of the Portfolio. Of course, we cannot predict how interest rates
may change.

Concentration Risk

When stocks in a particular industry make up 25% or more of a Portfolio, the
Portfolio 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 stocks of the industry.

Litigation and Legislation Risks

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

Future tax legislation could affect the value of the a Portfolio by:
o reducing the dividends-received deduction or

12
<PAGE>
o 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:
o adding the value of the Portfolio Securities, cash and any other Portfolio
assets;
o 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
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 a Portfolio.

If you sell your units before the final deferred sales fee payment, 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.
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 a secondary market continuously for more than 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 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 for a
higher price, but is not obligated to do so. 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 agent for 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 $1,000,000, 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

13
<PAGE>
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:
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
securities not reasonably practicable; and
o for any other period permitted by SEC order.

Rollover/Exchange Option

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

If you hold your Units with one of the Sponsors and notify your financial
adviser by , your units will be redeemed and the proceeds from the sale of the
securities will be reinvested in units of a new Baby Boom Economy Portfolios
Series. 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
Portfolios terminates.

If the participant in the rollover, you may realize taxable capital gain but may
not be entitled to a deduction for any capital loss recognized on the rollover.
You should consult your tax advisor om this regard.

If you continue to hold your Units, you may exchange units of a Portfolio in
this Series 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 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 Portfolio Works

Pricing

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

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 Portfolio 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.

The deferred sales fee is generally a monthly charge of $2.50 per 1,000 units
and is accrued in seven monthly 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.

14
<PAGE>
from the several installment accrual dates to the dates of actual sale of
securities to satisfy this liability.

Evaluations

The Trustee and the independent evaluator value 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. On holidays when the U.S. Government is closed (Columbus Day and
Veterans's Day), the portion of the net asset value relating to the U.S.
Government Treasury Securities will be based on the previous days' closing
price.

Income
o 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.
o Interest on any fixed income securities purchased on a when-issued basis or
for a delayed delivery does not begin to accrue until the securities are
delivered to the Portfolio. If a security 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 security as failed.
o The Trustee credits dividends received and any interest income to an Income
Account and other receipts to a Capital Account. The Trustee may establish a
reserve account by withdrawing from the these accounts amounts it considers
appropriate to pay any material liability. These accounts do not bear
interest.
o Each unit receives an equal share of distributions of interest and 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.

Expenses

The Trustee is paid a fee monthly. This fee includes an amount for estimated
organization costs 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.

15
<PAGE>
o expenses for keeping the Portfolio's registration statement current; and
o Portfolio termination expenses and any governmental charges.

The Sponsors are currently reimbursed up to 45 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 Series, 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
Portfolios also pay the Evaluator's fees.

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

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 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

Each Portfolio is a 'unit investment trust' governed by a Trust Indenture, a
contract among the Sponsors, the Trustee and the Evaluator, if any, 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 Portfolio without your written consent.

16
<PAGE>
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;
o it becomes incapable of acting or bankrupt or its affairs are taken over by
public authorities; or
o the Sponsors determine that its replacement is in your best interest.

Investors holding 51% of the units may remove the Trustee. The Evaluator may
resign or be removed by the Sponsors and the Trustee without consent of
investors. The Trustee may resign or be removed by the Sponsors 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 Portfolios; 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 Evaluator 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

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.

Underwriters' and Sponsors' Profits

Underwriters receive sales charges when they sell units. Sponsors also realize a
profit or loss on deposit of the securities. 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 stocks in the
Portfolio which were acquired from underwriting syndicates of which it was a
member.

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 during the first year.

Dealer Concession

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

Code of Ethics

Merrill Lynch, as agent for the Sponsors, has adopted a code of ethics requiring
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

18
<PAGE>
against the Portfolio 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 exptect that the computer system changes necessary to
prepare for the Year 2000 will cause any major operational difficulties for the
Portfolio. 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.

Advertising and Sales Literature

Advertising and sales literature may include brief descriptions of the principal
businesses of the companies represented in the Portfolio.

Taxes

The following summarizes the material 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.

Taxation of the Portfolio

Each Portfolio Fund intends to qualify for special tax treatment as a regulated
investment company so that it will not be subject to federal income tax on the
portion of its taxable income that it distributes to investors in a timely
manner.

Distributions

Distributions to you of a Portfolio's interest income, dividend income and gains
from securities it has held for one year or less will generally be taxed to you
as ordinary income. Distributions to you in excess of a Portfolio's taxable
income will be treated as a return of capital and will reduce your basis in your
units. To the extent such distributions exceed your basis, they will be treated
as gain from the sale of your units (as discussed below).

Distributions to you that are treated as ordinary income will constitute
dividends for federal income tax purposes. Corporate investors may be eligible
for the 70% dividends-received deduction with respect to these distributions.
You should consult your tax adviser in this regard.

Distributions to you of a Portfolio's net capital gain will generally be taxable
to you as long-term capital gain, regardless of how long you have held your
units, unless a Portfolio terminates in less than one year, in which case all
distributions from a Portfolio will generally be taxed to you as ordinary
income. Distributions that are taxable to you as long-term capital gains may be
eligible for the 20% maximum federal tax rate. You should consult your tax
advisor in this regard.

Gain or Loss Upon Disposition

You will generally recognize gain or loss when you dispose of your units by sale
or redemption. If you choose to roll over your investment in the Fund into a new
fund, you will generally recognize capital gain but you may not be entitled to a
deduction for any capital loss recognized on the rollover. You should consult
your tax advisor in this regard.
If you receive securities upon redemption of your units, you will generally
recognize gain or loss equal to the difference between your basis

19
<PAGE>
in your units and the fair market value of the securities received in
redemption.

If you net long-term capital gains exceed your net short-term capital losses,
the excess may be eligible for the 20% maximum federal tax rate. Any capital
gain or loss will generally be long-term if you have held your investment for
more than one year and short-term if you have held it for one year or less.
However, any capital loss on the sale or redemption of a unit you have held for
six months or less will be a long-term capital loss to the extent of any capital
gain dividends previously distributed to you by a Portfolio. 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 Basis in the Securities

Your aggregate basis in the units will generally be equal to the cost of your
units, including the initial sales charge. You should not increase your basis in
your units by deferred sales charges or organizational expenses, because 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 be deducted.

Foreign Investors

If you are a foreign investor and you are not engaged in a U.S. trade of
business, you will generally be subject to 30% withholding tax (or a lower
applicable treaty rate) on distributions. Because interest income of the type
that may be received by a Portfolio generally would not have been subject to
withholding if you had received it directly, an investment in the Accumulation
or Distribution Portfolios may be appropriate for you only when you can use a
foreign tax credit or corresponding tax benefit in respect of such withholding
taxes on a Portfolio's interest income. You should consult your tax adviser to
determine whether investment in a Portfolio is appropriate for you.

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.

REPORT OF INDEPENDENT ACCOUNTANTS

The Sponsors, Trustee and Holders of Equity Investor Fund, Baby Boom Economy
Portfolios 1999 Series, Defined Asset Funds (the 'Fund'):

We have audited the accompanying statements of condition and the related defined
portfolios included in the prospectus of the Fund as of , 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 ,
1999 in conformity with generally accepted accounting principles.

What You Can Expect From Your Investment

Income

The Portfolio will pay to you any income it has received two times during its
life. Because the Portfolio generally pays dividends as they are received,
individual income payments will fluctuate based upon the amount of dividends
declared and paid by each issuer. Other reasons your income may vary are:
o changes in the Portfolio because of additional securities purchases or
sales;
o a change in the Portfolio's expenses;
o the amount of dividends declared and paid; or
o elimination of one or more securities from the Portfolio because of
redemptions or sales.

There can be no assurance that any dividends will be declared or paid.

Records and Reports

You may request copies of securities evaluations to enable you to comply with
federal and state tax reporting requirements and 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 a Portfolio, the
Portfolio 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 stocks of the industry.

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 the Portfolio by:
o reducing the dividends-received deduction or
o increasing the corporate tax rate resulting in less money available for
dividend payments.

Selling or Exchanging Units

6
<PAGE>
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 a Portfolio.

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

Sponsors' Secondary Market

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

Selling Units to the Trustee

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.

7
<PAGE>
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 Portfolio Series if one is available.

If you participate in the rollover, you may realize taxable capital gain but may
not be entitled to a deduction for any capital loss recognized on the rollover.
You should consult your tax advisor om this regard.

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

How The Portfolio Works

Pricing

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

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 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

8
<PAGE>
or that system or, if closing sales prices are not available, at the mean
between the closing bid and offer prices.

Income
o 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.
o The Trustee credits dividends received and any interest income to an Income
Account and other receipts to a Capital Account. The Trustee may establish a
reserve account by withdrawing from the these accounts amounts it considers
appropriate to pay any material liability. These accounts do not bear
interest.
o Each unit receives an equal share of distributions of interest and 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.

Expenses

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

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

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

9
<PAGE>
a lien on Portfolio assets to secure reimbursement of Portfolio expenses and may
sell securities if cash is not available.

Portfolio Termination

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 Trustee may resign by notifying the Sponsors. The Sponsors may remove the
Trustee without your consent if:
o it fails to perform its duties;
o it becomes incapable of acting or bankrupt or its affairs are taken over by
public authorities; or
o 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 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 may petition a court to appoint a successor.

Sponsors.

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

Legal Opinion

special counsel for the Sponsors, has given an opinion that the units are
validly issued.
