RISK/RETURN SUMMARY

<TABLE>
<C> <S>
1. WHAT IS THE PORTFOLIO'S OBJECTIVE?
- The objective of this Defined Fund is
capital appreciation by investing for a
period of about one year in a portfolio
consisting of common stocks in the
technology sector.
- 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 and principal
distributions, if any.

2. WHAT IS THE PORTFOLIO'S INVESTMENT
STRATEGY?
- The Portfolio contains 100 common stocks
in the technology sector selected by the
Sponsor for capital appreciation.
- We selected Portfolio stocks by applying
a quantitative model developed by Bernard
V. Tew, chairman of Q.E.D. Investments,
the Portfolio Consultant.
- The Model is designed to identify those
technology stocks:
</TABLE>

<TABLE>
<S> <C>
-- with similar returns and dissimilar
price movement (low correlation); and
-- with a strong potential for capital
appreciation and to provide investment
results that exceed the Merrill Lynch
100.
</TABLE>

<TABLE>
<C> <S>
- The Merrill Lynch 100 is an equally
weighted index of the 100 largest
technology stocks by market
capitalization and trading volume. The
Portfolio consists of the same stocks,
reweighted in the Portfolio to enhance
investment results.
- To implement the Strategy the Portfolio
Consultant compiles the historical price
data of all securities that comprise the
Merrill Lynch 100.
</TABLE>

<TABLE>
<S> <C>
-- Using this historical price data and
incorporating risk reduction
techniques, the Portfolio Consultant
sets the stock weightings that the
Portfolio Consultant believes will have
a return greater than, but highly
correlated with, the return of the
Index.
</TABLE>

<TABLE>
<C> <S>
- The Portfolio plans to hold the stocks in
the Portfolio for about one year. At the
end of the year, we will liquidate the
Portfolio and apply the same Strategy to
select a new portfolio, if available.
- Each Technology 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 any time.

3. WHAT TECHNOLOGY INDUSTRY SECTORS ARE
REPRESENTED IN THE PORTFOLIO?

Based upon the principal business of each
issuer and current market values, the
Portfolio represents the following
technology industry groups:
</TABLE>

<TABLE>
- Internet Content/Software 18%
<C> <S>
- Electronic Components-Semiconductors 15
- Software 10
- Telecommunication
Equipment/Services 10
- Enterprise Software/Services 9
- Computers 5
- Computer Information/Services 5
- Networking Products 5
- Fiber Optics 4
- Circuits 3
- E-Commerce 3
- Office Automation & Equipment 3
- Computer-Integrated Systems 2
- Data Processing/Management 2
- Electronic Component/Products 2
- Memory Devices 2
- Audio/Video Products 1
- Computer Data Security 1
</TABLE>

<TABLE>
<C> <S>
4. WHAT ARE THE SIGNIFICANT RISKS?
YOU CAN LOSE MONEY BY INVESTING IN THE
PORTFOLIO. THIS CAN HAPPEN FOR VARIOUS
REASONS, INCLUDING:
- The Portfolio is composed of aggressive
growth stocks in the technology industry
that are subject to extreme price
volatility. Therefore, the Portfolio may
be considered speculative. Investors may
want to consider their risk tolerance and
investment time horizon before investing
in this Portfolio.
- Investors should be aware that the Model
was applied on July 3, 2000, and that the
Portfolio is generally fixed; because the
Merrill Lynch 100 is rebalanced annually
in December, or may otherwise change, the
stocks in the Portfolio will not always
reflect the current Merrill Lynch 100. A
subsequent application of the Model might
yield different stock weightings.

- Dividend rates on the stocks or share
prices may decline during the life of the
Portfolio.
- Because the Portfolio is concentrated in
stocks in the technology sector, adverse
developments in this industry may affect
the value of your units.
- The Portfolio may continue to purchase or
hold the stocks originally selected even
though their market value may have changed
or they may no longer be in the Merrill
Lynch 100.
- The Portfolio does not reflect any
investment recommendations of the Sponsor,
and any one or more of the stocks in the
Portfolio may, from time to time, be
subject to sell recommendations from the
Sponsor.

5. IS THIS PORTFOLIO APPROPRIATE FOR YOU?
Yes, if you want capital appreciation. You
will benefit from a professionally
selected and supervised portfolio whose
risk is reduced by investing in equity
securities of different issuers. Because
all of the Portfolio stocks are
concentrated in the technology sector,
this Portfolio is not designed to be a
complete equity investment program.

The Portfolio is NOT appropriate for you
if you are unwilling to take the
additional risk involved with an
aggressive growth equity investment. It is
not appropriate for you if you are seeking
preservation of capital or current income.
6. HOW HAS THE TECHNOLOGY PORTFOLIO PERFORMED
IN THE PAST?

The following table shows the actual
annualized pre-tax return to investors who
bought prior Technology Portfolios
starting in 1998. The return assumes that
investors reinvested all dividends and
paid the maximum sales fees. The return
figure reflects performance through June
30, 2000. Of course past performance is no
indication of future results.

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:

8. IS THE PORTFOLIO MANAGED?

Unlike a mutual fund, the Portfolio is not
managed and stocks are not sold because of
market changes. The Sponsor monitors the
portfolio and may instruct the Trustee to
sell securities under certain limited
circumstances. However, given the
investment philosophy of the Portfolio, the
Sponsor is not likely to do so.

9. HOW DO I BUY UNITS?
The minimum investment is $250.

You can buy units from the Sponsor and
other broker-dealers. Some banks may offer
units for sale through special arrangements
with the Sponsor, although certain legal
restrictions may apply.

UNIT PRICE PER 1,000 UNITS $999.90
(as of July 12, 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 above per 1,000
Units, 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.

10. HOW DO I SELL UNITS?
You may sell your units at any time to the
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 and the costs of
liquidating securities to meet the
redemption.

11. HOW ARE DISTRIBUTIONS MADE AND TAXED?
The Portfolio currently plans to distribute
any dividend income on the 25th of January
and June if you own units on the 10th of
those months. However, if the distribution
would be less than $1.00 per 1,000 units,
the income will be distributed at the next
scheduled distribution date or termination.
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
whether you reinvest your dividends in the
Portfolio. A portion of the dividend
payments may be used to pay expenses of the
Portfolio. Foreign investors' shares of
dividends will generally be subject to
withholding taxes.

12. 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
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 if your investment goals
change. In addition, you may exchange into
this Portfolio from certain other Defined
Asset Funds.

<PAGE>
WHAT YOU CAN EXPECT FROM YOUR INVESTMENT

INCOME

Any dividend income will be distributed to you twice during the life of the
Portfolio. There can be no assurance that any dividends will be declared or
paid.

RECORDS AND REPORTS

You will receive:
- 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
- tax information. THIS WILL ALSO BE SENT TO THE IRS. YOU MUST REPORT THE AMOUNT
OF INCOME RECEIVED. PLEASE CONTACT YOUR TAX ADVISER IN THIS REGARD.

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 regulation;
-- 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.

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.

6
<PAGE>
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:
- 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.

SPONSOR'S 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 will 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 we 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 $500,000, you may choose to receive
your distribution "in-kind." If you so choose, you will receive securities and
cash with a total

7
<PAGE>
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:
- 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 this Portfolio is about to terminate, you may have the option to roll your
proceeds into a new Technology Portfolio if one is available.

If you hold your units in a currently taxable account and notify your financial
adviser by August 14, 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 Technology Portfolio. If you
decide not to roll over your proceeds, you will receive a cash distribution (or,
if you are eligible and 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
Defined Technology 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 Defined Technology Portfolio.

The Portfolio will terminate by September 19, 2001. However, the Sponsor may
extend the termination date for a period no longer than 30 days without notice
to Unitholders. 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 if your investment goals change. 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.

8
<PAGE>
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
- legal expenses and other out-of-pocket expenses.

The deferred sales fee is generally a charge of $1.50 per 1,000 units and is
accrued in ten 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. (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 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 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. The Trustee credits dividends received to an Income
Account and other receipts to a Capital Account. The Trustee may establish a
reserve

9
<PAGE>
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:
- for extraordinary services and costs of indemnifying the Trustee and the
Sponsor;
- costs of actions taken to protect the Portfolio and other legal fees and
expenses;
- expenses for keeping the Portfolio's registration statement current; and
- Portfolio termination expenses and any governmental charges.

The Sponsor is 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 Sponsor.

The Sponsor 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 Sponsor for the creation and development of the Portfolio, including
determination 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 Sponsor's 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 (as a percentage of $1,000 invested) 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 to
$4,999,999 0.75%
$5,000,000 or more 0.35%
</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 Sponsor will pay advertising and selling expenses at no charge to the
Portfolio. If

10
<PAGE>
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 will affect the size
and 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;
- 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 Sponsor 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 Sponsor 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.

11
<PAGE>
The Trustee may resign by notifying the Sponsor. The Sponsor 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 Sponsor determines 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 Sponsor without the consent of investors. The
resignation or removal of the Trustee becomes effective when a successor accepts
appointment. The Sponsor 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 Sponsor fails to perform its duties or becomes bankrupt the Trustee may:
- remove it and appoint a replacement Sponsor;
- liquidate the Portfolio; or
- continue to act as Trustee without a Sponsor.

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

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,

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

The Sponsor is a Delaware corporation and it, or its predecessor, has acted as
sponsor to many unit investment trusts. As a registered broker-dealer the
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 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.

UNDERWRITER'S AND SPONSOR'S PROFITS

Underwriters receive sales charges when they sell units. Any cash made available
by you to the Sponsor before the settlement date for those units may be used in
the Sponsor's businesses to the extent permitted by federal law and may benefit
the Sponsor.

12
<PAGE>
The 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.

During the initial offering period, the Sponsor may realize profits or sustain
losses on units they hold due to fluctuations in the price per unit. The Sponsor
experienced a profit of $19.90 on the initial date of 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 Sponsor will also realize
profits or sustain losses in the amount of any difference between the prices at
which it buys units and the prices at which it resells or redeems them.

PUBLIC DISTRIBUTION

During the initial offering period, units will be distributed to the public by
the Sponsor 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.

The Sponsor does 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 Portfolio and the Sponsor have each adopted a code of ethics requiring
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

13
<PAGE>
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 would 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.

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 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.

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

TAXES

The following summarizes 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 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 a gain or loss when you dispose of your units for
cash (by sale or redemption), when you exchange units for units of another
Defined Asset Fund or when the Trustee disposes of the Securities in the
Portfolio. You generally

14
<PAGE>
will not recognize a gain or loss on an "in-kind" distribution to you of your
proportional share of the Portfolio Securities, whether it is in redemption of
your units or upon termination of the Portfolio. 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 August 14, 2001, you will recognize 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 a 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 that 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 portfolio will
equal your basis in the Securities that were rolled over from the previous
portfolio plus the proceeds (other than proceeds that were paid to you) from the
sale of Securities from the portfolio that were not rolled over. You should not
increase your basis in your units by deferred sales fees, 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 in 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 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 appropriate 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.

15
<PAGE>
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.

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.

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 Sponsor 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.

REPORT OF INDEPENDENT ACCOUNTANTS

The Sponsor, Trustee and Holders of Equity Investor Fund, Defined Technology
Portfolio 2000 Series D, Defined Asset Funds (the "Portfolio"):

We have audited the accompanying statement of condition and the related defined
portfolio included in the prospectus of the Portfolio as of July 13, 2000. This
financial statement is the responsibility of the Trustee. Our responsibility is
to express an opinion on this financial statement based on our audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statement is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statement. Our procedures included confirmation of an irrevocable letter of
credit deposited for the purchase of securities, as described in the statement
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
audit provides a reasonable basis for our opinion.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the financial position of the Portfolio as of July 13,
2000 in accordance with accounting principles generally accepted in the United
States of America.

------------

(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 July 12,
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 $325,912.18 and deposited with the Trustee.
The amount of the letter of credit includes $325,932.08 for the purchase of
securities.

(2) A portion of the Public Offering 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 $1.53 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 the actual organization
costs exceed the estimated aggregate amount shown above, the Sponsor will
pay for 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 $999.90 per 1,000 Units offering price only for that day.
The Public Offering 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 July 12, 2000.

(5) Assumes the maximum initial sales charge per 1,000 units of 1.00% of the
Public Offering Price. A deferred sales charge of $1.50 per 1,000 Units is
payable on November 1, November 15 and on 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 Sponsor 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.
