(1) Each listed Equity Security is valued at its last closing sale price
and each Treasury Obligation is valued at its last offering price. If an
Equity Security is not listed, or if no closing sale price exists, it is
valued at its closing ask price. Evaluations for purposes of determining
the purchase, sale or redemption price of Units are made as of the close
of trading on the New York Stock Exchange ("NYSE") (generally 4:00 p.m.
Eastern time) on each day on which it is open (the "Evaluation Time").

(2) The maximum sales charge consists of an initial sales charge, a
deferred sales charge and the creation and development fee. See "Fee
Table" and "Public Offering."

(3) The Public Offering Price shown above reflects the value of the
Securities on the business day prior to the Initial Date of Deposit. No
investor will purchase Units at this price. The price you pay for your
Units will be based on their valuation at the Evaluation Time on the
date you purchase your Units. On the Initial Date of Deposit, the Public
Offering Price per Unit will not include any accumulated dividends on
the Equity Securities. After this date, a pro rata share of any
accumulated dividends on the Equity Securities will be included.

(4) Until the earlier of six months after the Initial Date of Deposit or
the end of the initial offering period the Sponsor's Initial Repurchase
Price per Unit and the Redemption Price per Unit will include the
creation and development fee and estimated organization costs per Unit
set forth under "Fee Table." After such date, the Sponsor's Repurchase
Price and Redemption Price per Unit will not include such creation and
development fee and estimated organization costs. See "Redeeming Your
Units."

(5) See "Amending or Terminating the Indenture."

(6) Distributions from the Capital Account will be made monthly on the
last day of each month to Unit holders of record on the fifteenth day of
such month if the amount available for distribution equals at least
$1.00 per 100 Units. In any case, the Trustee will distribute any funds
in the Capital Account in December of each year.

This Fee Table describes the fees and expenses that you may, directly or
indirectly, pay if you buy and hold Units of the Trust. See "Public
Offering" and "Expenses and Charges." Although the Trust has a term of
approximately ____ years and is a unit investment trust rather than a
mutual fund, this information allows you to compare fees.

                                 Example

This example is intended to help you compare the cost of investing in
the Trust with the cost of investing in other investment products. The
example assumes that you invest $10,000 in the Trust for the periods
shown and then sell your Units at the end of those periods. The example
also assumes a 5% return on your investment each year and that the
Trust's operating expenses stay the same. The example does not take into
consideration transaction fees which may be charged by certain
broker/dealers for processing redemption requests. Although your actual
costs may vary, based on these assumptions your costs would be:

1 Year            3 Years           5 Years           10 Years
______            _______           _______           _______
$                 $                 $                 $

_____________
<FN>

(a) The combination of the initial and deferred sales charge comprises
what we refer to as the "transactional sales charge." The initial sales
charge is actually equal to the difference between the maximum sales
charge of 5.50% and the sum of any remaining deferred sales charge and
creation and development fee.

(b) The deferred sales charge is a fixed dollar amount equal to $.400 per
Unit which, as a percentage of the Public Offering Price, will vary over
time. The deferred sales charge will be deducted in three monthly
installments commencing September 19, 2003.

(c) The creation and development fee compensates the Sponsor for creating
and developing the Trust. The creation and development fee is a charge
of $.050 per Unit collected at the end of the initial offering period
which is expected to be approximately six months from the Initial Date
of Deposit. If the price you pay for your Units exceeds $    per Unit,
the creation and development fee will be less than    %; if the price
you pay for your Units is less than $    per Unit, the creation and
development fee will exceed    %.

(d) Estimated organization costs will be deducted from the assets of the
Trust at the earlier of six months after the Initial Date of Deposit or
the end of the initial offering period.

(e) Each of the fees listed herein is assessed on a fixed dollar amount
per Unit basis which, as a percentage of average net assets, will vary
over time.

(f) Other operating expenses, however, do not include brokerage costs and
other portfolio transaction fees. In certain circumstances the Trust may
incur additional expenses not set forth above. See "Expenses and Charges."

                   Report of Independent Auditors

The Sponsor, First Trust Portfolios L.P., and Unit Holders
FT 666

We have audited the accompanying statement of net assets, including the
schedule of investments, of FT 666, comprising The Key 3 Growth and
Treasury Securities Portfolio, Series 3 (the "Trust"), as of the opening
of business on March __, 2003 (Initial Date of Deposit). This statement
of net assets is the responsibility of the Trust's Sponsor. Our
responsibility is to express an opinion on this statement of net assets
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 statement of net assets is free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the
amounts and disclosures in the statement of net assets. Our procedures
included confirmation of the irrevocable letter of credit held by
JPMorgan Chase Bank, the Trustee, and deposited in the Trust for the
purchase of Securities, as shown in the statement of net assets as of
the opening of business on March __, 2003, by correspondence with the
Trustee. An audit also includes assessing the accounting principles used
and significant estimates made by the Trust's Sponsor, as well as
evaluating the overall presentation of the statement of net assets. We
believe that our audit of the statement of net assets provides a
reasonable basis for our opinion.

In our opinion, the statement of net assets referred to above presents
fairly, in all material respects, the financial position of FT 666,
comprising The Key 3 Growth and Treasury Securities Portfolio, Series 3,
at the opening of business on March __, 2003 (Initial Date of Deposit)
in conformity with accounting principles generally accepted in the

                    NOTES TO STATEMENT OF NET ASSETS

(1) Aggregate cost of the Securities listed under "Schedule of
Investments" is based on their aggregate underlying value.

(2) An irrevocable letter of credit issued by JPMorgan Chase Bank, of
which $200,000 will be allocated to the Trust, has been deposited with
the Trustee as collateral, covering the monies necessary for the
purchase of the Securities according to their purchase contracts.

(3) A portion of the Public Offering Price consists of an amount
sufficient to reimburse the Sponsor for all or a portion of the costs of
establishing the Trust. These costs have been estimated at $.0290 per
Unit for the Trust. A payment will be made at the earlier of six months
after the Initial Date of Deposit or the end of the initial offering
period to an account maintained by the Trustee from which the obligation
of the investors to the Sponsor will be satisfied. To the extent that
actual organization costs are greater than the estimated amount, only
the estimated organization costs added to the Public Offering Price will
be reimbursed to the Sponsor and deducted from the assets of the Trust.

(4) Represents the amount of mandatory deferred sales charge
distributions of $.400 per Unit, payable to the Sponsor in three
approximately equal monthly installments beginning on September 19, 2003
and on the twentieth day of each month thereafter (or if such day is not
a business day, on the preceding business day) through November 20,
2003. If Unit holders redeem Units before November 20, 2003, they will
have to pay the remaining amount of the deferred sales charge applicable
to such Units when they redeem them.

(5) The creation and development fee ($.050 per Unit) is payable by the
Trust on behalf of Unit holders out of assets of the Trust at the end of
the initial offering period. If Units are redeemed prior to the close of
the initial offering period, the fee will not be deducted from the
proceeds.

(6) The aggregate cost to investors in the Trust includes a maximum
sales charge (comprised of an initial sales charge, a deferred sales
charge and the creation and development fee) computed at the rate of
5.50% of the Public Offering Price per Unit (equivalent to    % of the
net amount invested, exclusive of the deferred sales charge and the
creation and development fee), assuming no reduction of the maximum
sales charge as set forth under "Public Offering."

                    NOTES TO SCHEDULE OF INVESTMENTS

(1) The Treasury Obligations were purchased at a discount from their par
value because there is no stated interest income thereon (such
securities are often referred to as zero coupon U.S. Treasury bonds).
Over the life of the Treasury Obligations the value increases, so that
upon maturity the holders will receive 100% of the principal amount
thereof. All Securities are represented by regular way contracts to
purchase such Securities which are backed by an irrevocable letter of
credit deposited with the Trustee. The Sponsor entered into purchase
contracts for the Securities on March __, 2003. Such purchase contracts
are expected to settle within three business days.

(2) The cost of the Securities to the Trust represents the aggregate
underlying value with respect to the Securities acquired (generally
determined by the closing sale prices of the listed Equity Securities,
the ask prices of the over-the-counter traded Equity Securities and the
offering side price of the Treasury Obligations at the Evaluation Time
on the business day preceding the Initial Date of Deposit). The offering
side price of the Treasury Obligations is greater than the bid side
price of the Treasury Obligations which is the basis on which the
Redemption Price per Unit will be determined. The value of the
Securities based on the bid side price of the Treasury Obligations and
the value of the Equity Securities is $_______. The valuation of the
Securities has been determined by the Evaluator, an affiliate of the
Sponsor. The cost of the Securities to the Sponsor and the Sponsor's
profit or loss (which is the difference between the cost of the
Securities to the Sponsor and the cost of the Securities to the Trust)
are $    and $   , respectively.

                       The FT Series

The FT Series Defined.

We, First Trust Portfolios L.P. (the "Sponsor"), have created hundreds
of similar yet separate series of a unit investment trust which we have
named the FT Series. The series to which this prospectus relates, FT
666, consists of a single portfolio known as The Key 3 Growth and
Treasury Securities Portfolio, Series 3.

The Trust was created under the laws of the State of New York by a Trust
Agreement (the "Indenture") dated the Initial Date of Deposit. This
agreement, entered into among First Trust Portfolios L.P., as Sponsor,
JPMorgan Chase Bank as Trustee and First Trust Advisors L.P. as
Portfolio Supervisor and Evaluator, governs the operation of the Trust.

YOU MAY GET MORE SPECIFIC DETAILS CONCERNING THE NATURE, STRUCTURE AND
RISKS OF THIS PRODUCT IN AN "INFORMATION SUPPLEMENT" BY CALLING THE
TRUSTEE AT 1-800-682-7520.

How We Created the Trust.

On the Initial Date of Deposit, we deposited a portfolio of zero coupon
U.S. Treasury bonds and common stocks with the Trustee, and in turn, the
Trustee delivered documents to us representing our ownership of the
Trust in the form of units ("Units").

After the Initial Date of Deposit, we may deposit additional Securities
in the Trust, or cash (including a letter of credit) with instructions
to buy more Securities, to create new Units for sale. If we create
additional Units, we will attempt, to the extent practicable, to
maintain the percentage relationship established among the Securities on
the Initial Date of Deposit (as set forth in "Schedule of Investments"),
and not the actual percentage relationship existing on the day we are
creating new Units, since the two may differ. This difference may be due
to the sale, redemption or liquidation of any of the Securities.

Since the prices of the Securities will fluctuate daily, the ratio of
Securities in the Trust, on a market value basis, will also change
daily. The portion of Securities represented by each Unit will not
change as a result of the deposit of additional Securities or cash in
the Trust. If we deposit cash, you and new investors may experience a
dilution of your investment. This is because prices of Securities will
fluctuate between the time of the cash deposit and the purchase of the
Securities, and because the Trust pays the associated brokerage fees. To
reduce this dilution, the Trust will try to buy the Securities as close
to the Evaluation Time and as close to the evaluation price as possible.
In addition, because the Trust pays the brokerage fees associated with
the creation of new Units and with the sale of Securities to meet
redemption and exchange requests, frequent redemption and exchange
activity will likely result in higher brokerage expenses.

An affiliate of the Trustee may receive these brokerage fees or the
Trustee may retain and pay us (or our affiliate) to act as agent for the
Trust to buy Securities. If we or an affiliate of ours act as agent to
the Trust, we will be subject to the restrictions under the Investment
Company Act of 1940, as amended.

We cannot guarantee that the Trust will keep its present size and
composition for any length of time. Securities may periodically be sold
under certain circumstances, and the proceeds from these sales will be
used to meet Trust obligations or distributed to Unit holders, but will
not be reinvested. However, Securities will not be sold to take
advantage of market fluctuations or changes in anticipated rates of
appreciation or depreciation, or if they no longer meet the criteria by
which they were selected. You will not be able to dispose of or vote any
of the Securities in the Trust. As the holder of the Securities, the
Trustee will vote all of the Equity Securities and will do so based on
our instructions.

Neither we nor the Trustee will be liable for a failure in any of the
Securities. However, if a contract for the purchase of any of the
Securities initially deposited in the Trust fails, unless we can
purchase substitute Securities ("Replacement Securities") we will refund
to you that portion of the purchase price and transactional sales charge
resulting from the failed contract on the next Income Distribution Date.
Any Replacement Security the Trust acquires will be identical to those
from the failed contract.

                         Portfolio

Objectives.

The Trust's objective is to provide investors with principal protection
by investing approximately __% of the Trust's portfolio in zero coupon
U.S. Treasury Obligations and to provide the potential for capital
appreciation by investing approximately __% of the Trust's portfolio in
common stocks.

As an investor in this Trust, you may be able to accomplish two goals-
safety and growth. We seek to accomplish these goals by investing the
Trust in professionally selected stocks along with zero coupon U.S.

Page 9

Treasury Bonds. While the Trust's initial offering price will be
approximately $9.75 per Unit, and the market value will fluctuate during
its life, the minimum maturity value will be at least $10.00 per Unit.

Zero coupon U.S. Treasury Bonds are purchased at a discount to their
maturity value and they pay their full face value at a specified
maturity date. Instead of paying interest, the earnings are added to the
original investment, increasing their value as they approach maturity.
Although no interest payments will be distributed during the life of the
Trust, investors are subject to income taxes at ordinary rates as if a
distribution had occurred. Zero coupon U.S. Treasury Bonds are also
backed by the full faith and credit of the U.S. Government; however,
Units of the Trust are not.

The Trust invests in zero coupon U.S. Treasury Bonds as well as the
three sectors that have become important parts of the prosperity and
growth that we have seen in the United States-financial services,
healthcare and technology. We believe that each of the three industries
will remain at the forefront as the principal drivers behind the economy
in the future. Many significant trends have had positive influences on
these industries including:

- - Industry Consolidation

- - The Baby Boom Generation

- - An Aging Population

- - Technological Innovation

We believe that the complete impact of these trends has yet to take
shape within each industry. In the last ten years, either financial
services, healthcare or technology have been the best performing
Standard & Poor's 500 Composite Stock Price Index ("S&P 500 Index")
sector seven times and in nine of the last ten years, at least two of
the three sectors have outperformed the S&P 500 Index in any one year.

Financial Services. The financial services industry has seen several
significant changes during its storied history. Perhaps none have been
more noteworthy than the modernization of the industry through the
overturn of the Glass-Steagall Act.

- - The Baby Boom Generation: Nearly three out of ten people in the United
States are baby boomers. Scores of them have already started, or soon
will start, planning for their retirement just as they are entering
their peak earning years.

- - Deregulation & Consolidation: With the Glass-Steagall Act no longer a
barrier, companies throughout the industry are now better able to create
"financial supermarkets" that offer services including traditional
banking, insurance underwriting, securities underwriting, investment
brokerage and merchant banking. The number of FDIC-insured commercial
banks has declined from over 13,000 in 1993 to approximately 9,500 as of
June 30, 2002. [FDIC Historical Statistics on Banking]

Healthcare. The healthcare industry has been responsible for several
discoveries that have led to new treatments that have resulted in people
living longer, healthier lives. More recent research relating to areas
such as genomics is providing avenues of growth never before imagined.
Previously untreatable diseases are now often manageable or even
curable. Additionally, the average life expectancy at birth in 1965 was
approximately 70 years, whereas in 2000 it was approximately 77 years.

result of the Human Genome Project, new doors have been opened to
breakthrough research. It is now estimated that the number of targets
for new drug interventions has grown from 500 to over 3000. [Standard &
Poor's Industry Surveys]

Technology. If you are looking to invest in cutting-edge technology, you
may not need to look any further than the Internet. Though still
considered to be in its infancy, the Internet has already had an impact
on business, consumers and nearly every aspect of today's society. In
addition, new technology acceptance time is declining. While it took the
telephone 35 years, the television 26 years, the cell phone 16 years and
the personal computer 13 years to reach one-quarter of U.S. households,
it took only seven years for the Internet to do the same. [Red Herring]

You should be aware that predictions stated herein for the above
industries may not be realized. In addition, the Securities contained in
the Trust are not intended to be representative of the selected
industries as a whole and the performance of the Trust is expected to
differ from that of its comparative industries. Of course, as with any
similar investment, there can be no guarantee that the objective of the
Trust will be achieved. See "Risk Factors" for a discussion of the risks
of investing in the Trust.

                       Risk Factors

Price Volatility. The Trust invests in Treasury Obligations and common
stocks. The value of the Trust's Units will fluctuate with changes in
the value of these Treasury Obligations and common stocks. Common stock
prices fluctuate for several reasons including changes in investors'
perceptions of the financial condition of an issuer or the general
condition of the relevant stock market, such as the current market
volatility, or when political or economic events affecting the issuers
occur. In addition, common stock prices may be particularly sensitive to
rising interest rates, as the cost of capital rises and borrowing costs
increase.

The value of the Treasury Obligations will be adversely affected by
decreases in bond prices and increases in interest rates. Zero coupon
bonds do not provide for the payment of any current interest. The buyer
receives only the right to receive a final payment of the face amount of
the bond at its maturity. Zero coupon bonds are subject to substantially
greater price fluctuations during periods of changing market interest
rates than are bonds of comparable quality that pay interest currently.

Because the Trust is not managed, the Trustee will not sell Securities
in response to or in anticipation of market fluctuations, as is common
in managed investments. As with any investment, we cannot guarantee that
the performance of the Trust will be positive over any period of time or
that you won't lose money. Units of the Trust are not deposits of any
bank and are not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.

Distributions. There is no guarantee that the issuers of the Equity
Securities will declare dividends in the future or that if declared they
will either remain at current levels or increase over time.

Because the Treasury Obligations pay no interest until their maturity,
Equity Securities may have to be sold to pay Trust expenses or meet
redemption requests. As the Treasury Obligations ensure that the Trust
will be able to provide $10 per Unit at the Trust's termination, they
will not be sold to pay expenses of the Trust or to meet redemption
requests unless their sale will not reduce the per Unit termination
value below $10. The sale of a portion of the Equity Securities in these
situations will reduce the capital appreciation potential of the Trust.
In addition, although the Treasury Obligations pay no interest until
they mature, they are deemed for federal income tax purposes to have
been issued with original issue discount which accrues on a daily basis
over their life. Each year you must include as part of your taxable
income the amount of any accreted original issue discount on the
Treasury Obligations. Therefore, you will be taxed on the Treasury
Obligations even prior to receiving any cash distributions. See "Tax
Status" for further information.

Financial Services Industry. Certain of the Securities in the Trust are
invested in the financial services industry, which includes banks and
thrifts, financial services and insurance companies, and investment
firms. Banks, thrifts and their holding companies are especially subject
to the adverse effects of economic recession; volatile interest rates;
portfolio concentrations in geographic markets and in commercial and
residential real estate loans; and competition from new entrants in
their fields of business. Although recently-enacted legislation repealed
most of the barriers which separated the banking, insurance and
securities industries, these industries are still extensively regulated
at both the federal and state level and may be adversely affected by
increased regulations.

Banks and thrifts face increased competition from nontraditional lending
sources as regulatory changes, such as the recently enacted financial-
services overhaul legislation, permit new entrants to offer various
financial products. Technological advances such as the Internet allow
these nontraditional lending sources to cut overhead and permit the more
efficient use of customer data.

Brokerage firms, broker/dealers, investment banks, finance companies and
mutual fund companies are also financial services providers. These
companies compete with banks and thrifts to provide traditional
financial service products, in addition to their traditional services,
such as brokerage and investment advice. In addition, all financial
service companies face shrinking profit margins due to new competitors,
the cost of new technology and the pressure to compete globally.

Companies involved in the insurance industry are engaged in
underwriting, selling, distributing or placing of property and casualty,

Page 11

life or health insurance. Insurance company profits are affected by many
factors, including interest rate movements, the imposition of premium
rate caps, competition and pressure to compete globally. Property and
casualty insurance profits may also be affected by weather catastrophes,
acts of terrorism and other disasters. Life and health insurance profits
may be affected by mortality rates. Already extensively regulated,
insurance companies' profits may also be adversely affected by increased
government regulations or tax law changes.

Healthcare Industry. The Trust also invests in healthcare stocks.
General risks of such companies involve extensive competition, generic
drug sales or the loss of patent protection, product liability
litigation and increased government regulation. Research and development
costs of bringing new drugs to market are substantial, and there is no
guarantee that the product will ever come to market. Healthcare facility
operators may be affected by the demand for services, efforts by
government or insurers to limit rates, restriction of government
financial assistance and competition from other providers.

Technology Industry. The Trust also contains Securities from the
technology industry. Technology companies are generally subject to the
risks of rapidly changing technologies; short product life cycles;
fierce competition; aggressive pricing and reduced profit margins; the
loss of patent, copyright and trademark protections; cyclical market
patterns; evolving industry standards and frequent new product
introductions. Technology companies may be smaller and less experienced
companies, with limited product lines, markets or financial resources
and fewer experienced management or marketing personnel. Technology
company stocks, especially those which are Internet-related, have
experienced extreme price and volume fluctuations that are often
unrelated to their operating performance. Also, the stocks of many
Internet companies have exceptionally high price-to-earnings ratios with
little or no earnings histories.

Legislation/Litigation. From time to time, various legislative
initiatives are proposed in the United States and abroad which may have
a negative impact on certain companies represented in the Trust.
Litigation regarding any of the issuers of the Equity Securities, or the
industries represented in the Trust, may negatively impact the share
prices of these Equity Securities. In addition, litigation may be
initiated on a variety of grounds affecting the Treasury Obligations. We
cannot predict what impact any pending or proposed legislation or
pending or threatened litigation will have on the share prices of the
Securities.

Foreign Stocks. Certain of the Securities in the Trust are issued by
foreign companies, which makes the Trust subject to more risks than if
it invested solely in domestic common stocks. These Securities are
either directly listed on a U.S. securities exchange or are in the form
of American Depositary Receipts ("ADRs") which are listed on a U.S.
securities exchange. Risks of foreign common stocks include higher
brokerage costs; different accounting standards; expropriation,
nationalization or other adverse political or economic developments;
currency devaluations, blockages or transfer restrictions; restrictions
on foreign investments and exchange of securities; inadequate financial
information; and lack of liquidity of certain foreign markets.

Termination Value. The Trust has been designed to return to investors at
least $10 per Unit only at its termination. Units purchased at a price
greater than $10 per Unit will not provide you with total principal
protection, but will provide you with a minimum maturity value of $10.00
per Unit if you hold your Units until maturity of the Trust. If you
redeem or sell your Units prior to termination of the Trust, the amount
you will receive will be affected by the values at that time of the
Treasury Obligations and of the Equity Securities, and you may receive
less than $10 per Unit.

We have obtained the foregoing descriptions from sources we deem
reliable. We have not independently verified the provided information
either in terms of accuracy or completeness.

                      Public Offering

The Public Offering Price.

You may buy Units at the Public Offering Price, the per Unit price of
which is comprised of the following:

- - The aggregate offering side evaluation of the Treasury Obligations;

- -  The aggregate underlying value of the Equity Securities;

- -  The amount of any cash in the Income and Capital Accounts;

- -  Dividends receivable on Equity Securities; and

- -  The maximum sales charge (which combines an initial upfront sales
charge, a deferred sales charge and the creation and development fee).

The price you pay for your Units will differ from the amount stated
under "Summary of Essential Information" due to various factors,
including fluctuations in the prices of the Securities and changes in
the value of the Income and/or Capital Accounts.

Although you are not required to pay for your Units until three business
days following your order (the "date of settlement"), you may pay before
then. You will become the owner of Units ("Record Owner") on the date of
settlement if payment has been received. If you pay for your Units
before the date of settlement, we may use your payment during this time
and it may be considered a benefit to us, subject to the limitations of
the Securities Exchange Act of 1934.

Organization Costs. Equity Securities purchased with the portion of the
Public Offering Price intended to be used to reimburse the Sponsor for
the Trust's organization costs (including costs of preparing the
registration statement, the Indenture and other closing documents,
registering Units with the Securities and Exchange Commission ("SEC")
and states, the initial audit of the Trust portfolio, legal fees and the
initial fees and expenses of the Trustee) will be purchased in the same
proportionate relationship as all the Equity Securities contained in the
Trust. Equity Securities will be sold to reimburse the Sponsor for the
Trust's organization costs at the earlier of six months after the
Initial Date of Deposit or the end of the initial offering period (a
significantly shorter time period than the life of the Trust). During
the period ending with the earlier of six months after the Initial Date
of Deposit or the end of the initial offering period, there may be a
decrease in the value of the Equity Securities. To the extent the
proceeds from the sale of these Equity Securities are insufficient to
repay the Sponsor for Trust organization costs, the Trustee will sell
additional Equity Securities to allow the Trust to fully reimburse the
Sponsor. In that event, the net asset value per Unit of the Trust will
be reduced by the amount of additional Equity Securities sold. Although
the dollar amount of the reimbursement due to the Sponsor will remain
fixed and will never exceed the per Unit amount set forth in "Notes to
Statement of Net Assets," this will result in a greater effective cost
per Unit to Unit holders for the reimbursement to the Sponsor. To the
extent actual organization costs are less than the estimated amount,
only the actual organization costs will be deducted from the assets of
the Trust. When Equity Securities are sold to reimburse the Sponsor for
organization costs, the Trustee will sell such Equity Securities, to the
extent practicable, which will maintain the same proportionate
relationship among the Equity Securities contained in the Trust as
existed prior to such sale.

Minimum Purchase.

The minimum amount you can purchase of the Trust is $1,000 worth of
Units ($500 if you are purchasing Units for your Individual Retirement
Account or any other qualified retirement plan).

Transactional Sales Charge.

The transactional sales charge you will pay has both an initial and a
deferred component. The initial sales charge, which you will pay at the
time of purchase, is equal to the difference between the maximum sales
charge (5.50% of the Public Offering Price) and the sum of the maximum
remaining deferred sales charge and creation and development fee
(initially equal to $.450 per Unit). This initial sales charge is
initially equal to approximately ____% of the Public Offering Price of a

Page 13

Unit, but will vary from ___% depending on the purchase price of your
Units and as deferred sales charge and creation and development fee
payments are made. When the Public Offering Price exceeds $    per Unit,
the initial sales charge will exceed ____% of the Public Offering Price.
After the initial offering period, the initial sales charge will be
reduced by the amount of the creation and development fee.

Monthly Deferred Sales Charge. In addition, three monthly deferred sales
charge payments of approximately $.1334 per Unit will be deducted from
the Trust's assets on approximately the twentieth day of each month from
September 19, 2003 through November 20, 2003. If you buy Units at a
price of less than $___ per Unit, the dollar amount of the deferred
sales charge will not change, but the deferred sales charge on a
percentage basis will be more than    % of the Public Offering Price.

If you purchase Units after the last deferred sales charge payment has
been assessed, your transactional sales charge will consist of a one-
time initial sales charge of 5.00% of the Public Offering Price per Unit
(equivalent to      % of the net amount invested). The transactional
sales charge will be reduced by 1/2 of 1% on each subsequent March 31,
commencing March 31, 2004, to a minimum transactional sales charge of
3.00%.

Discounts for Certain Persons.

If you invest at least $50,000 (except if you are purchasing for "Fee
Accounts" as described below), the maximum sales charge is reduced as
described below.

If you invest                         Your maximum
(in thousands):*                      sales charge will be:
_________________                     ________________
$50 but less than $100                5.25%
$100 but less than $250               5.00%
$250 but less than $500               4.50%
$500 but less than $1,000             3.50%
$1,000 or more                        2.60%

* Breakpoint sales charges are also applied on a Unit basis utilizing a
breakpoint equivalent in the above table of $10 per Unit and will be
applied on whichever basis is more favorable to the investor. The
breakpoints will be adjusted to take into consideration purchase orders
stated in dollars which cannot be completely fulfilled due to the
requirement that only whole Units be issued.

The reduced sales charge for quantity purchases will apply only to
purchases made by the same person on any one day from any one dealer. To
help you reach the above levels, you can combine the Units you purchase
of the Trust with any other same day purchases of other trusts for which
we are Principal Underwriter and are currently in the initial offering
period. In addition, we will also consider Units you purchase in the
name of your spouse or child under 21 years of age to be purchases by
you. The reduced sales charges will also apply to a trustee or other
fiduciary purchasing Units for a single trust estate or single fiduciary
account. You must inform your dealer of any combined purchases before
the sale in order to be eligible for the reduced sales charge. Any
reduced sales charge is the responsibility of the party making the sale.

You may use termination proceeds from other unit investment trusts with
a similar strategy as the Trust or your redemption or termination
proceeds from any unit investment trust we sponsor to purchase Units of
the Trust during the initial offering period at the Public Offering
Price less 1.00%. However, if you invest redemption or termination
proceeds of $500,000 or more in Units of the Trust, the maximum sales
charge on your Units will be limited to the maximum sales charge for the
applicable amount invested in the table set forth above. Please note
that if you purchase Units of the Trust in this manner using redemption
proceeds from trusts which assess the amount of any remaining deferred
sales charge at redemption, you should be aware that any deferred sales
charge remaining on these units will be deducted from those redemption
proceeds.

Investors purchasing Units through registered broker/dealers who charge
periodic fees in lieu of commissions or who charge for financial
planning, investment advisory or asset management services or provide
these or comparable services as part of an investment account where a
comprehensive "wrap fee" or similar charge is imposed ("Fee Accounts")
will not be assessed the transactional sales charge described in this
section on the purchase of Units. Certain Fee Accounts Unit holders may
be assessed transaction or other account fees on the purchase and/or
redemption of such Units by their broker/dealer or other processing
organizations for providing certain transaction or account activities.
We reserve the right to limit or deny purchases of Units not subject to
the transactional sales charge by investors whose frequent trading
activity we determine to be detrimental to the Trust.

Employees, officers and directors (and immediate family members) of the
Sponsor, our related companies, dealers and their affiliates, and
vendors providing services to us may purchase Units at the Public
Offering Price less the applicable dealer concession. Immediate family
members include spouses, children, grandchildren, parents, grandparents,
siblings, mothers-in-law, fathers-in-law, sons-in-law, daughters-in-law,
brothers-in-law and sisters-in-law, and trustees, custodians or
fiduciaries for the benefit of such persons.

Page 14


The Sponsor and certain dealers may establish a schedule where
employees, officers and directors of such dealers can purchase Units of
the Trust at the Public Offering Price less the established schedule
amount, which is designed to compensate such dealers for activities
relating to the sale of Units (the "Employee Dealer Concession").

You will be charged the deferred sales charge per Unit regardless of any
discounts. However, if you are eligible to receive a discount such that
the maximum sales charge you must pay is less than the applicable
maximum deferred sales charge, including Fee Accounts Units, you will be
credited the difference between your maximum sales charge and the
maximum deferred sales charge at the time you buy your Units. If you
elect to have distributions reinvested into additional Units of the
Trust, in addition to the reinvestment Units you receive you will also
be credited additional Units with a dollar value at the time of
reinvestment sufficient to cover the amount of any remaining deferred
sales charge to be collected on such reinvestment Units. The dollar
value of these additional credited Units (as with all Units) will
fluctuate over time, and may be less on the dates deferred sales charges
are collected than their value at the time they were issued.

As Sponsor, we will also receive, and the Unit holders will pay, a
creation and development fee. See "Expenses and Charges" for a
description of the services provided for this fee.

The Value of the Securities.

The Evaluator will determine the aggregate underlying value of the
Securities in the Trust as of the Evaluation Time on each business day
and will adjust the Public Offering Price of the Units according to this
valuation. This Public Offering Price will be effective for all orders
received before the Evaluation Time on each such day. If we or the
Trustee receive orders for purchases, sales or redemptions after that
time, or on a day which is not a business day, they will be held until
the next determination of price. The term "business day" as used in this
prospectus will exclude Saturdays, Sundays and certain national holidays
on which the NYSE is closed.

The aggregate underlying value of the Treasury Obligations will be
determined on the basis of current offering prices.

The aggregate underlying value of the Equity Securities in the Trust
will be determined as follows: if the Equity Securities are listed on a
securities exchange or The Nasdaq Stock Market, their value is generally
based on the closing sale prices on that exchange or system (unless it
is determined that these prices are not appropriate as a basis for
valuation). However, if there is no closing sale price on that exchange
or system, they are valued based on the closing ask prices. If the
Equity Securities are not so listed, or, if so listed and the principal
market for them is other than on that exchange or system, their value
will generally be based on the current ask prices on the over-the-
counter market (unless it is determined that these prices are not
appropriate as a basis for valuation). If current ask prices are
unavailable, the valuation of the Equity Securities is generally
determined:

a) On the basis of current ask prices for comparable equity securities;

b) By appraising the value of the Equity Securities on the ask side of
the market; or

c) By any combination of the above.

After the initial offering period is over, the aggregate underlying
value of the Securities will be determined as set forth above, except
that bid prices are used instead of ask or offer prices when necessary.

                   Distribution of Units

We intend to qualify Units of the Trust for sale in a number of states.
All Units will be sold at the then current Public Offering Price.

Dealer Concessions.

Dealers and other selling agents can purchase Units at prices which
reflect a concession or agency commission of 4.0% of the Public Offering
Price per Unit (or 65% of the maximum transactional sales charge for
secondary market sales). However, for Units subject to a transactional
sales charge which are purchased using redemption or termination
proceeds, this amount will be reduced to 3.0% of the sales price of
these Units (2.0% for purchases of $500,000 but less than $1,000,000 and
1.10% for purchases of $1,000,000 or more).

Eligible dealer firms and other selling agents who sell Units of the
Trust during the initial offering period in the dollar amounts shown
below will be entitled to the following additional sales concessions as
a percentage of the Public Offering Price:

Total Sales                           Additional
(in millions):                        Concession:
_________________                     ________________
$1 but less than $5                   0.10%
$5 but less than $10                  0.15%
$10 or more                           0.20%

Dealers and other selling agents will not receive a concession on the
sale of Units which are not subject to a transactional sales charge, but

Page 15

such Units will be included in determining whether the above volume
sales levels are met. Eligible dealer firms and other selling agents
include entities that are providing marketing support for First Trust
unit investment trusts by distributing or permitting the distribution of
marketing materials and other product information. Eligible dealer firms
and other selling agents will not include firms that solely provide
clearing services to other broker/dealer firms. In addition, dealers and
other selling agents who, during any consecutive 12-month period, sell
at least $250 million or $500 million worth of primary market units of
unit investment trusts sponsored by us will receive a concession of
$2,500 or $5,000, respectively, in the month following the achievement
of this level. We reserve the right to change the amount of concessions
or agency commissions from time to time. Certain commercial banks may be
making Units of the Trust available to their customers on an agency
basis. A portion of the transactional sales charge paid by these
customers is kept by or given to the banks in the amounts shown above.

Award Programs.

From time to time we may sponsor programs which provide awards to a
dealer's registered representatives who have sold a minimum number of
Units during a specified time period. We may also pay fees to qualifying
dealers for services or activities which are meant to result in sales of
Units of the Trust. In addition, we will pay to dealers who sponsor
sales contests or recognition programs that conform to our criteria, or
participate in our sales programs, amounts equal to no more than the
total applicable transactional sales charge on Units sold by such
persons during such programs. We make these payments out of our own
assets and not out of Trust assets. These programs will not change the
price you pay for your Units.

Advertising and Investment Comparisons.

Advertising materials regarding the Trust may discuss several topics,
including: developing a long-term financial plan; working with your
financial professional; the nature and risks of various investment
strategies and unit investment trusts that could help you reach your
financial goals; the importance of discipline; how the Trust operates;
how securities are selected; various unit investment trust features such
as convenience and costs; and options available for certain types of
unit investment trusts. These materials may include descriptions of the
securities represented in the Trust, research analysis of why they were
selected and information relating to the qualifications of the persons
or entities providing the research analysis. In addition, they may
include research opinions on the economy and securities included and a
list of investment products generally appropriate for pursuing those
recommendations.

From time to time we may compare the estimated returns of the Trust
(which may show performance net of the expenses and charges the Trust
would have incurred) and returns over specified periods of other similar
trusts we sponsor in our advertising and sales materials, with (1)
returns on other taxable investments such as the common stocks
comprising various market indexes, corporate or U.S. Government bonds,
bank CDs and money market accounts or funds, (2) performance data from
Morningstar Publications, Inc. or (3) information from publications such
as Money, The New York Times, U.S. News and World Report, BusinessWeek,
Forbes or Fortune. The investment characteristics of the Trust differ
from other comparative investments. You should not assume that these
performance comparisons will be representative of the Trust's future
performance. We may also, from time to time, use advertising which
classifies trusts according to capitalization and/or investment style.

                   The Sponsor's Profits

We will receive a gross sales commission equal to the maximum
transactional sales charge per Unit less any reduction as stated in
"Public Offering." We will also receive the amount of any collected
creation and development fee. Also, any difference between our cost to
purchase the Securities and the price at which we sell them to the Trust
is considered a profit or loss. (See Note 2 of "Notes to Schedule of
Investments.") During the initial offering period, dealers and others
may also realize profits or sustain losses as a result of fluctuations
after the Date of Deposit in the Public Offering Price they receive when
they sell the Units.

In maintaining a market for Units, any difference between the price at
which we purchase Units and the price at which we sell or redeem them
will be a profit or loss to us.

                   The Secondary Market

Although not obligated, we intend to maintain a market for the Units
after the initial offering period and continuously offer to purchase
Units at prices based on the Redemption Price per Unit.

We will pay all expenses to maintain a secondary market, except the
Evaluator fees, Trustee costs to transfer and record the ownership of
Units and costs incurred in annually updating the Trust's registration

Page 16

statement. We may discontinue purchases of Units at any time. IF YOU
WISH TO DISPOSE OF YOUR UNITS, YOU SHOULD ASK US FOR THE CURRENT MARKET
PRICES BEFORE MAKING A TENDER FOR REDEMPTION TO THE TRUSTEE. If you sell
or redeem your Units before you have paid the total deferred sales
charge on your Units, you will have to pay the remainder at that time.

                   How We Purchase Units

The Trustee will notify us of any tender of Units for redemption. If our
bid at that time is equal to or greater than the Redemption Price per
Unit, we may purchase the Units. You will receive your proceeds from the
sale no later than if they were redeemed by the Trustee. We may tender
Units we hold to the Trustee for redemption as any other Units. If we
elect not to purchase Units, the Trustee may sell tendered Units in the
over-the-counter market, if any. However, the amount you will receive is
the same as you would have received on redemption of the Units.

                   Expenses and Charges

The estimated annual expenses of the Trust are listed under "Fee Table."
If actual expenses exceed the estimate, the Trust will bear the excess,
other than for excess annual audit costs. The Trustee will pay operating
expenses of the Trust from the Income Account of the Trust if funds are
available, and then from the Capital Account. The Income and Capital
Accounts are noninterest-bearing to Unit holders, so the Trustee may
earn interest on these funds, thus benefiting from their use.

First Trust Advisors L.P., an affiliate of ours, acts as Portfolio
Supervisor and Evaluator and will be compensated for providing portfolio
supervisory services and evaluation services as well as bookkeeping and
other administrative services to the Trust. In providing portfolio
supervisory services, the Portfolio Supervisor may purchase research
services from a number of sources, which may include underwriters or
dealers of the Trust. As Sponsor, we will receive brokerage fees when
the Trust uses us (or an affiliate of ours) as agent in buying or
selling Securities. Legal and regulatory filing fees and expenses
associated with updating the Trust's registration statement yearly are
also chargeable to the Trust.

The fees payable to First Trust Advisors L.P. and the Trustee are based
on the largest aggregate number of Units of the Trust outstanding at any
time during the calendar year, except during the initial offering
period, in which case these fees are calculated based on the largest
number of Units outstanding during the period for which compensation is
paid. These fees may be adjusted for inflation without Unit holders'
approval, but in no case will the annual fees paid to us or our
affiliates for providing services to all unit investment trusts be more
than the actual cost of providing such service in such year.

As Sponsor, we will receive a fee from the Trust for creating and
developing the Trust, including determining the Trust's objectives,
policies, composition and size, selecting service providers and
information services and for providing other similar administrative and
ministerial functions. The "creation and development fee" is a charge of
$.050 per Unit outstanding at the end of the initial offering period.
The Trustee will deduct this amount from the Trust's assets as of the
close of the initial offering period. We do not use this fee to pay
distribution expenses or as compensation for sales efforts. This fee
will not be deducted from your proceeds if you sell or redeem your Units
before the end of the initial offering period.

In addition to the Trust's operating expenses, and the fees described
above, the Trust may also incur the following charges:

- - All legal and annual auditing expenses of the Trustee according to its
responsibilities under the Indenture;

- - The expenses and costs incurred by the Trustee to protect the Trust
and your rights and interests;

- - Fees for any extraordinary services the Trustee performed under the
Indenture;

- - Payment for any loss, liability or expense the Trustee incurred
without negligence, bad faith or willful misconduct on its part, in
connection with its acceptance or administration of the Trust;

- - Payment for any loss, liability or expenses we incurred without
negligence, bad faith or willful misconduct in acting as Depositor of
the Trust; and/or

- - All taxes and other government charges imposed upon the Securities or
any part of the Trust.

The above expenses and the Trustee's annual fee are secured by a lien on
the Trust. Since dividend income on the Equity Securities is
unpredictable, we cannot guarantee that dividends will be sufficient to
meet any or all expenses of the Trust. If there is not enough cash in
the Income or Capital Account, the Trustee has the power to sell
Securities to make cash available to pay these charges which may result
in capital gains or losses to you. See "Tax Status." However, Treasury
Obligations will not be sold to pay expenses unless their sale will not
reduce the per Unit termination value below $10.00.

Page 17


The Trust will be audited annually, so long as we are making a secondary
market for Units. We will bear the costs of these annual audits to the
extent the cost exceeds $.0050 per Unit. Otherwise, the Trust will pay
for the audit. You may request a copy of the audited financial
statements from the Trustee.

                        Tax Status

This section summarizes some of the main U.S. federal income tax
consequences of owning Units of the Trust. This section is current as of
the date of this prospectus. Tax laws and interpretations change
frequently, and these summaries do not describe all of the tax
consequences to all taxpayers. For example, these summaries generally do
not describe your situation if you are a corporation, a non-U.S. person,
a broker/dealer, or other investor with special circumstances. In
addition, this section does not describe your state or foreign taxes. As
with any investment, you should consult your own tax professional about
your particular consequences. In addition, the Internal Revenue Service
issued new withholding and reporting regulations effective January 1,
2001. Foreign investors should consult their own tax advisors regarding
the tax consequences of these regulations.

Assets of the Trust.

 The Trust will hold one or more of the following: (i) zero coupon U.S.
Treasury bonds (the "Treasury Obligations") and (ii) stock in domestic
and foreign corporations (the "Stocks"). All of the assets held by the
Trust constitute the "Trust Assets." For purposes of this federal tax
discussion, it is assumed that the Stocks constitute equity for federal
income tax purposes.

Trust Status.

The Trust will not be taxed as a corporation for federal income tax
purposes. As a Unit owner, you will be treated as the owner of a pro
rata portion of the Trust Assets, and as such you will be considered to
have received a pro rata share of income (e.g., dividends, accruals of
original issue discount, and capital gains, if any) from the Trust
Assets when such income would be considered to be received by you if you
directly owned the Trust Assets. This is true even if you elect to have
your distributions automatically reinvested into additional Units. In
addition, the income from the Trust Assets which you must take into
account for federal income tax purposes is not reduced by amounts used
to pay Trust expenses (including the deferred sales charge, if any).

Your Tax Basis and Income or Loss upon Disposition.

If your Trust disposes of Trust Assets, you will generally recognize
gain or loss. If you dispose of your Units or redeem your Units for
cash, you will also generally recognize gain or loss. To determine the
amount of this gain or loss, you must subtract your tax basis in the
related Trust Assets from your share of the total amount received in the
transaction. You can generally determine your initial tax basis in each
Trust Asset by apportioning the cost of your Units, generally including
sales charges, among each Trust Asset ratably according to their value
on the date you purchase your Units. In certain circumstances, however,
you may have to adjust your tax basis after you purchase your Units (for
example, in the case of accrual of original issue discount, as discussed
below, or certain dividends that exceed a corporation's accumulated
earnings and profits).

If you are an individual, the maximum marginal federal tax rate for net
capital gain is generally 20% (10% for certain taxpayers in the 10% and
15% tax brackets). The 20% rate is reduced to 18% and the 10% rate is
reduced to 8% for long-term gains from most property acquired after
December 31, 2000, with a holding period of more than five years.

Net capital gain equals net long-term capital gain minus net short-term
capital loss for the taxable year. Capital gain or loss is long-term if
the holding period for the asset is more than one year and is short-term
if the holding period for the asset is one year or less. You must
exclude the date you purchase your Units to determine your holding
period. The tax rates for capital gains realized from assets held for
one year or less are generally the same as for ordinary income. The
Internal Revenue Code, however, treats certain capital gains as ordinary
income in special situations.

Original Issue Discount.

The Treasury Obligations will generally be treated as having original
issue discount. This original issue discount is generally equal to the
difference between the amount payable on the due date and your purchase
price allocable to the Treasury Obligations. Original issue discount
accrues on a daily basis and is generally treated as interest income for
federal income tax purposes as it accrues. Your basis of each Treasury
Obligation must be increased as original issue discount accrues. The
rules relating to original issue discount are very complex and special
rules apply in numerous circumstances.

In-Kind Distributions.

Under certain circumstances, as described in this prospectus, you may
request a distribution of Trust Assets (an "In-Kind Distribution") when

Page 18

you redeem your Units or at the Trust's termination. By electing to
receive an In-Kind Distribution, you will receive whole Trust Assets
plus, possibly, cash.

You will not recognize gain or loss if you only receive Trust Assets in
exchange for your pro rata portion of the Trust Assets held by the
Trust. However, if you also receive cash in exchange for a Trust Asset
or a fractional share of a Trust Asset, you will generally recognize
gain or loss based on the difference between the amount of cash you
receive and your tax basis in such Trust Asset or fractional share.

Limitations on the Deductibility of Trust Expenses.

Generally, for federal income tax purposes, you must take into account
your full pro rata share of the Trust's income, even if some of that
income is used to pay Trust expenses. You may deduct your pro rata share
of each expense paid by the Trust to the same extent as if you directly
paid the expense. You may, however, be required to treat some or all of
the expenses of the Trust as miscellaneous itemized deductions.
Individuals may only deduct certain miscellaneous itemized deductions to
the extent they exceed 2% of adjusted gross income.

Foreign, State and Local Taxes.

Some distributions by the Trust may be subject to foreign withholding
taxes. Any dividends withheld will nevertheless be treated as income to
you. However, because you are deemed to have paid directly your share of
foreign taxes that have been paid or accrued by the Trust, you may be
entitled to a foreign tax credit or deduction for U.S. tax purposes with
respect to such taxes.

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

                     Retirement Plans

You may purchase Units of the Trust for:

- - Individual Retirement Accounts

- - Keogh Plans

- - Pension funds, and

- - Other tax-deferred retirement plans.

Generally, the federal income tax on capital gains and income received
in each of the above plans is deferred until you receive distributions.
These distributions are generally treated as ordinary income but may, in
some cases, be eligible for special averaging or tax-deferred rollover
treatment. Before participating in a plan like this, you should review
the tax laws regarding these plans and consult your attorney or tax
advisor. Brokerage firms and other financial institutions offer these
plans with varying fees and charges.

                  Rights of Unit Holders

Unit Ownership.

The Trustee will treat as Record Owner of Units persons registered as
such on its books. It is your responsibility to notify the Trustee when
you become Record Owner, but normally your broker/dealer provides this
notice. You may elect to hold your Units in either certificated or
uncertificated form. All Fee Accounts Units, however, will be held in
uncertificated form.

Certificated Units. When you purchase your Units, you can request that
they be evidenced by certificates, which will be delivered shortly after
your order. Certificates will be issued in fully registered form,
transferable only on the books of the Trustee in denominations of one
Unit or any multiple thereof. You can transfer or redeem your
certificated Units by endorsing and surrendering the certificate to the
Trustee, along with a written instrument of transfer. You must sign your
name exactly as it appears on the face of the certificate with your
signature guaranteed by an eligible institution. In certain cases the
Trustee may require additional documentation before they will transfer
or redeem your Units.

You may be required to pay a nominal fee to the Trustee for each
certificate reissued or transferred, and to pay any government charge
that may be imposed for each transfer or exchange. If a certificate gets
lost, stolen or destroyed, you may be required to furnish indemnity to
the Trustee to receive replacement certificates. You must surrender
mutilated certificates to the Trustee for replacement.

Uncertificated Units. You may also choose to hold your Units in
uncertificated form. If you choose this option, the Trustee will
establish an account for you and credit your account with the number of
Units you purchase. Within two business days of the issuance or transfer
of Units held in uncertificated form, the Trustee will send you:

- - A written initial transaction statement containing a description of
your Trust;

- - The number of Units issued or transferred;

- - Your name, address and Taxpayer Identification Number ("TIN");

- - A notation of any liens or restrictions of the issuer and any adverse
claims; and

- - The date the transfer was registered.

Page 19


Uncertificated Units may be transferred the same way as certificated
Units, except that no certificate needs to be presented to the Trustee.
Also, no certificate will be issued when the transfer takes place unless
you request it. You may at any time request that the Trustee issue
certificates for your Units.

Unit Holder Reports.

In connection with each distribution, the Trustee will provide you with
a statement detailing the per Unit amount of income (if any)
distributed. After the end of each calendar year, the Trustee will
provide you:

- - A summary of transactions in the Trust for the year;

- - A list of any Securities sold during the year and the Securities held
at the end of that year by the Trust;

- - The Redemption Price per Unit, computed on the 31st day of December of
such year (or the last business day before); and

- - Amounts of income and capital distributed during the year.

You may request from the Trustee copies of the evaluations of the
Securities as prepared by the Evaluator to enable you to comply with
federal and state tax reporting requirements.

              Income and Capital Distributions

You will begin receiving distributions on your Units only after you
become a Record Owner. The Trustee will credit any dividends received on
the Trust's Securities to the Income Account. All other receipts, such
as return of capital, are credited to the Capital Account.

The Trustee will distribute any net income in the Income Account on or
near the Income Distribution Dates to Unit holders of record on the
preceding Income Distribution Record Date. See "Summary of Essential
Information." No income distribution will be paid if accrued expenses of
the Trust exceed amounts in the Income Account on the Income
Distribution Dates. Distribution amounts will vary with changes in the
Trust's fees and expenses, in dividends received and with the sale of
Securities. Income from original issue discount on the Treasury
Obligations will not be distributed currently, but you will be subject
to federal income tax as if a distribution had occurred. See "Tax
Status." The Trustee will distribute amounts in the Capital Account, net
of amounts designated to meet redemptions, pay the deferred sales charge
or pay expenses, on the last day of each month to Unit holders of record
on the fifteenth day of each month provided the amount equals at least
$1.00 per 100 Units. If the Trustee does not have your TIN it is
required to withhold a certain percentage of your distribution and
deliver such amount to the Internal Revenue Service ("IRS"). You may
recover this amount by giving your TIN to the Trustee, or when you file
a tax return. However, you should check your statements to make sure the
Trustee has your TIN to avoid this "back-up withholding."

We anticipate that there will be enough money in the Capital Account to
pay the deferred sales charge. If not, the Trustee may sell Securities
to meet the shortfall. However, Treasury Obligations will not be sold to
pay the deferred sales charge unless their sale will not reduce the per
Unit termination value below $10.00.

Within a reasonable time after the Trust is terminated you will receive
a pro rata share of the money from the sale of the Securities. However,
if you are eligible, you may elect to receive an In-Kind Distribution as
described under "Amending or Terminating the Indenture." You will
receive a pro rata share of any other assets remaining in the Trust,
after deducting any unpaid expenses.

The Trustee may establish reserves (the "Reserve Account") within the
Trust to cover anticipated state and local taxes and any governmental
charges to be paid out of the Trust.

Distribution Reinvestment Option. You may elect to have each
distribution of income and/or capital reinvested into additional Units
of the Trust by notifying the Trustee at least 10 days before any Record
Date. Each later distribution of income and/or capital on your Units
will be reinvested by the Trustee into additional Units of the Trust.
There is no transactional sales charge on Units acquired through the
Distribution Reinvestment Option, as discussed under "Public Offering."
This option may not be available in all states. PLEASE NOTE THAT EVEN IF
YOU REINVEST DISTRIBUTIONS, THEY ARE STILL CONSIDERED DISTRIBUTIONS FOR
INCOME TAX PURPOSES.

                   Redeeming Your Units

You may redeem all or a portion of your Units at any time by sending the
certificates representing the Units you want to redeem to the Trustee at
its unit investment trust office. If your Units are uncertificated, you
need only deliver a request for redemption to the Trustee. In either
case, the certificates or the redemption request must be properly
endorsed with proper instruments of transfer and signature guarantees as
explained in "Rights of Unit Holders-Unit Ownership" (or by providing
satisfactory indemnity if the certificates were lost, stolen, or
destroyed). No redemption fee will be charged, but you are responsible
for any governmental charges that apply. Certain broker/dealers may

Page 20

charge a transaction fee for processing redemption requests. Units
redeemed directly through the Trustee are not subject to such
transaction fees. Three business days after the day you tender your
Units (the "Date of Tender") you will receive cash in an amount for each
Unit equal to the Redemption Price per Unit calculated at the Evaluation
Time on the Date of Tender.

The Date of Tender is considered to be the date on which the Trustee
receives your certificates or redemption request (if such day is a day
the NYSE is open for trading). However, if your certificates or
redemption request are received after 4:00 p.m. Eastern time (or after
any earlier closing time on a day on which the NYSE is scheduled in
advance to close at such earlier time), the Date of Tender is the next
day the NYSE is open for trading.

Any amounts paid on redemption representing income will be withdrawn
from the Income Account if funds are available for that purpose, or from
the Capital Account. All other amounts paid on redemption will be taken
from the Capital Account. The IRS will require the Trustee to withhold a
portion of your redemption proceeds if the Trustee does not have your
TIN, as generally discussed under "Income and Capital Distributions."

If you tender at least 2,500 Units, or such other amount as required by
your broker/dealer, for redemption, rather than receiving cash, you may
elect to receive an In-Kind Distribution in an amount equal to the
Redemption Price per Unit by making this request in writing to the
Trustee at the time of tender. However, to be eligible to participate in
the In-Kind Distribution option at redemption, Fee Accounts Unit holders
must hold their Units through the end of the initial offering period. No
In-Kind Distribution requests submitted during the nine business days
prior to the Trust's Mandatory Termination Date will be honored. Where
possible, the Trustee will make an In-Kind Distribution by distributing
each of the Equity Securities in book-entry form to your bank or
broker/dealer account at the Depository Trust Company. The Trustee will
subtract any customary transfer and registration charges from your In-
Kind Distribution. As a tendering Unit holder, you will receive your pro
rata number of whole shares of the Equity Securities that make up the
portfolio, and cash from the Capital Account equal to the value of the
U.S. Treasury Bonds and fractional shares of Equity Securities to which
you are entitled.

The Trustee may sell Securities to make funds available for redemption.
However, Treasury Obligations will not be sold to the extent that it
affects the Trust's ability to pay its minimum maturity value at
termination. If Securities are sold, the size and diversification of the
Trust will be reduced. These sales may result in lower prices than if
the Securities were sold at a different time.

Your right to redeem Units (and therefore, your right to receive
payment) may be delayed:

If the NYSE is closed (other than customary weekend and holiday closings);

If the SEC determines that trading on the NYSE is restricted or that an
emergency exists making sale or evaluation of the Securities not
reasonably practical; or

For any other period permitted by SEC order.

The Trustee is not liable to any person for any loss or damage which may
result from such a suspension or postponement.

The Redemption Price.

The Redemption Price per Unit is determined by the Trustee by:

adding

1. cash in the Income and Capital Accounts not designated to purchase
Securities;

2. the aggregate underlying value of the Securities held in the Trust; and

3. dividends receivable on the Equity Securities trading ex-dividend as
of the date of computation; and

deducting

1. any applicable taxes or governmental charges that need to be paid out
of the Trust;

2. any amounts owed to the Trustee for its advances;

3. estimated accrued expenses of the Trust, if any;

4. cash held for distribution to Unit holders of record of the Trust as
of the business day before the evaluation being made; and

5. other liabilities incurred by the Trust; and

dividing

1. the result by the number of outstanding Units of the Trust.

Any remaining deferred sales charge on the Units when you redeem them
will be deducted from your redemption proceeds. In addition, until the
earlier of six months after the Initial Date of Deposit or the end of
the initial offering period, the Redemption Price per Unit will include
estimated organization costs as set forth under "Fee Table."

            Removing Securities from the Trust

The portfolio of the Trust is not managed. However, we may, but are not
required to, direct the Trustee to dispose of an Equity Security in
certain limited circumstances, including situations in which:

Page 21


- - The issuer of an Equity Security defaults in the payment of a declared
dividend;

- - Any action or proceeding prevents the payment of dividends;

- - There is any legal question or impediment affecting an Equity Security;

- - The issuer of an Equity Security has breached a covenant which would
affect the payment of dividends, the issuer's credit standing, or
otherwise damage the sound investment character of such Equity Security;

- - The issuer has defaulted on the payment on any other of its
outstanding obligations;

- - There has been a public tender offer made for an Equity Security or a
merger or acquisition is announced affecting an Equity Security, and
that in our opinion the sale or tender of the Equity Security is in the
best interest of Unit holders; or

- - The price of the Equity Security has declined to such an extent, or
such other credit factors exist, that in our opinion keeping the Equity
Security would be harmful to the Trust.

Except in the limited instance in which the Trust acquires Replacement
Securities, as described in "The FT Series," the Trust may not acquire
any securities or other property other than the Securities. The Trustee,
on behalf of the Trust, will reject any offer for new or exchanged
securities or property in exchange for a Security, such as those
acquired in a merger or other transaction. If such exchanged securities
or property are nevertheless acquired by the Trust, at our instruction,
they will either be sold or held in the Trust. In making the
determination as to whether to sell or hold the exchanged securities or
property we may get advice from the Portfolio Supervisor. Any proceeds
received from the sale of Securities, exchanged securities or property
will be credited to the Capital Account for distribution to Unit holders
or to meet redemption requests. The Trustee may retain and pay us or an
affiliate of ours to act as agent for the Trust to facilitate selling
Securities, exchanged securities or property from the Trust. If we or
our affiliate act in this capacity, we will be held subject to the
restrictions under the Investment Company Act of 1940, as amended.

The Trustee may sell Securities designated by us; or, absent our
direction, at its own discretion, in order to meet redemption requests
or pay expenses. Treasury Obligations will not be sold to meet
redemption requests or pay expenses unless their sale will not reduce
the per Unit termination value below $10.00. In designating Securities
to be sold, we will try to maintain the proportionate relationship among
the Securities. If this is not possible, the composition and
diversification of the Trust may be changed. To get the best price for
the Trust we may specify minimum amounts (generally 100 shares) in which
blocks of Securities are to be sold. We may consider sales of units of
unit investment trusts we sponsor when we make recommendations to the
Trustee as to which broker/dealers they select to execute the Trust's
portfolio transactions, or when acting as agent for the Trust in
acquiring or selling Securities on behalf of the Trust.

           Amending or Terminating the Indenture

Amendments. The Indenture may be amended by us and the Trustee 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 interests (as determined by us and the Trustee).

Termination. As provided by the Indenture, the Trust will terminate on
the Mandatory Termination Date. The Trust may be terminated prior to the
Mandatory Termination Date:

- - Upon the consent of 100% of the Unit holders; or

- - In the event that Units of the Trust not yet sold aggregating more
than 60% of the Units of such Trust are tendered for redemption by
underwriters, including the Sponsor.

Prior to termination, the Trustee will send written notice to all Unit
holders which will specify how you should tender your certificates, if
any, to the Trustee. If the Trust is terminated due to this last reason,
we will refund your entire transactional sales charge; however,
termination of the Trust before the Mandatory Termination Date for any
other stated reason will result in all remaining unpaid deferred sales
charges on your Units being deducted from your termination proceeds.

Unless terminated earlier, the Trustee will begin to sell Equity
Securities in connection with the termination of the Trust during the
period beginning nine business days prior to, and no later than, the
Mandatory Termination Date. We will determine the manner and timing of
the sale of Equity Securities. Because the Trustee must sell the Equity
Securities within a relatively short period of time, the sale of the
Equity Securities as part of the termination process may result in a
lower sales price than might otherwise be realized if such sale were not
required at this time.

Page 22


If you own at least 2,500 Units of the Trust, or such other amount as
required by your broker/dealer, the Trustee will send the registered
account holders a form at least 30 days prior to the Mandatory
Termination Date which will enable you to receive an In-Kind
Distribution (reduced by customary transfer and registration charges and
subject to any additional restrictions imposed on Fee Accounts by "wrap
fee" plans) rather than the typical cash distribution. See "Tax Status"
for additional information. If you elect the In-Kind Distribution option
you will receive your pro rata number of whole shares of the Equity
Securities that make up the portfolio, and cash from the Capital Account
equal to the value of the U.S. Treasury Bonds and fractional shares of
Equity Securities to which you are entitled. You must notify the Trustee
at least ten business days prior to the Mandatory Termination Date if
you elect this In-Kind Distribution option. If you do not elect to
participate in the In-Kind Distribution option, you will receive a cash
distribution from the sale of the remaining Securities, along with your
interest in the Income and Capital Accounts, within a reasonable time
after the Trust is terminated. Regardless of the distribution involved,
the Trustee will deduct from the Trust any accrued costs, expenses,
advances or indemnities provided for by the Indenture, including
estimated compensation of the Trustee and costs of liquidation and any
amounts required as a reserve to pay any taxes or other governmental
charges.

Risk Factors

Securities. An investment in Units should be made with an understanding
of the risks which an investment in common stocks entails, including the
risk that the financial condition of the issuers of the Securities or
the general condition of the relevant stock market may worsen, and the
value of the Securities and therefore the value of the Units may
decline. Common stocks are especially susceptible to general stock
market movements and to volatile increases and decreases of value, as
market confidence in and perceptions of the issuers change. These
perceptions are based on unpredictable factors, including expectations
regarding government, economic, monetary and fiscal policies, inflation
and interest rates, economic expansion or contraction, and global or
regional political, economic or banking crises. Both U.S. and foreign
markets have experienced substantial volatility and significant declines
recently as a result of certain or all of these factors.

Dividends. Shareholders of common stocks have rights to receive payments
from the issuers of those common stocks that are generally subordinate
to those of creditors of, or holders of debt obligations or preferred
stocks of, such issuers. Common stocks do not represent an obligation of
the issuer and, therefore, do not offer any assurance of income or
provide the same degree of protection of capital as do debt securities.
The issuance of additional debt securities or preferred stock will
create prior claims for payment of principal, interest and dividends
which could adversely affect the ability and inclination of the issuer
to declare or pay dividends on its common stock or the rights of holders
of common stock with respect to assets of the issuer upon liquidation or
bankruptcy.

Treasury Obligations. An investment in Units should be made with an
understanding of the risks which an investment in zero coupon U.S.
Treasury Obligations entails. Such Treasury Obligations are purchased at
a deep discount because the buyer obtains only the right to a fixed
payment at a fixed date in the future and does not receive any periodic
interest payments. The effect of owning deep discount bonds which do not
make current interest payments (such as the Treasury Obligations) is
that a fixed yield is earned not only on the original investment, but
also, in effect, on all earnings during the life of the discount
obligation. This implicit reinvestment of earnings at the same rate
eliminates the risk of being unable to reinvest the income on such
obligations at a rate as high as the implicit yield on the discount
obligation, but at the same time eliminates the holder's ability to
reinvest at higher rates in the future. For this reason, the Treasury
Obligations are subject to substantially greater price fluctuations
during periods of changing interest rates than are securities of
comparable quality which make regular interest payments.

Foreign Issuers. Since certain of the Securities included in the Trust
consist of securities of foreign issuers, an investment in the Trust
involves certain investment risks that are different in some respects
from an investment in a trust which invests entirely in the securities
of domestic issuers. These investment risks include future political or
governmental restrictions which might adversely affect the payment or

Page 1

receipt of payment of dividends on the relevant Securities, the
possibility that the financial condition of the issuers of the
Securities may become impaired or that the general condition of the
relevant stock market may worsen (both of which would contribute
directly to a decrease in the value of the Securities and thus in the
value of the Units), the limited liquidity and relatively small market
capitalization of the relevant securities market, expropriation or
confiscatory taxation, economic uncertainties and foreign currency
devaluations and fluctuations. In addition, for foreign issuers that are
not subject to the reporting requirements of the Securities Exchange Act
of 1934, there may be less publicly available information than is
available from a domestic issuer. Also, foreign issuers are not
necessarily subject to uniform accounting, auditing and financial
reporting standards, practices and requirements comparable to those
applicable to domestic issuers. The securities of many foreign issuers
are less liquid and their prices more volatile than securities of
comparable domestic issuers. In addition, fixed brokerage commissions
and other transaction costs on foreign securities exchanges are
generally higher than in the United States and there is generally less
government supervision and regulation of exchanges, brokers and issuers
in foreign countries than there is in the United States. However, due to
the nature of the issuers of the Securities selected for the Trust, the
Sponsor believes that adequate information will be available to allow
the Supervisor to provide portfolio surveillance for the Trust.

Securities issued by non-U.S. issuers generally pay dividends in foreign
currencies and are principally traded in foreign currencies. Therefore,
there is a risk that the U.S. dollar value of these securities will vary
with fluctuations in the U.S. dollar foreign exchange rates for the
various Securities.

On the basis of the best information available to the Sponsor at the
present time, none of the Securities in the Trust are subject to
exchange control restrictions under existing law which would materially
interfere with payment to the Trust of dividends due on, or proceeds
from the sale of, the Securities. However, there can be no assurance
that exchange control regulations might not be adopted in the future
which might adversely affect payment to the Trust. The adoption of
exchange control regulations and other legal restrictions could have an
adverse impact on the marketability of international securities in the
Trust and on the ability of the Trust to satisfy its obligation to
redeem Units tendered to the Trustee for redemption. In addition,
restrictions on the settlement of transactions on either the purchase or
sale side, or both, could cause delays or increase the costs associated
with the purchase and sale of the foreign Securities and correspondingly
could affect the price of the Units.

Investors should be aware that it may not be possible to buy all
Securities at the same time because of the unavailability of any
Security, and restrictions applicable to the Trust relating to the
purchase of a Security by reason of the federal securities laws or
otherwise.

Foreign securities generally have not been registered under the
Securities Act of 1933 and may not be exempt from the registration
requirements of such Act. Sales of non-exempt Securities by the Trust in
the United States securities markets are subject to severe restrictions
and may not be practicable. Accordingly, sales of these Securities by
the Trust will generally be effected only in foreign securities markets.
Although the Sponsor does not believe that the Trust will encounter
obstacles in disposing of the Securities, investors should realize that
the 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. The value of the Securities will be
adversely affected if trading markets for the Securities are limited or
absent.

Financial Services. An investment in Units of the Trust should be made
with an understanding of the problems and risks inherent in the bank and
financial services sector in general.

Banks, thrifts and their holding companies are especially subject to the
adverse effects of economic recession, volatile interest rates,
portfolio concentrations in geographic markets and in commercial and
residential real estate loans, and competition from new entrants in
their fields of business. Banks and thrifts are highly dependent on net
interest margin. Recently, bank profits have come under pressure as net
interest margins have contracted, but volume gains have been strong in
both commercial and consumer products. There is no certainty that such
conditions will continue. Bank and thrift institutions had received
significant consumer mortgage fee income as a result of activity in
mortgage and refinance markets. As initial home purchasing and
refinancing activity subsided, this income diminished. Economic
conditions in the real estate markets, which have been weak in the past,
can have a substantial effect upon banks and thrifts because they
generally have a portion of their assets invested in loans secured by
real estate. Banks, thrifts and their holding companies are subject to
extensive federal regulation and, when such institutions are state-
chartered, to state regulation as well. Such regulations impose strict
capital requirements and limitations on the nature and extent of
business activities that banks and thrifts may pursue. Furthermore, bank
regulators have a wide range of discretion in connection with their
supervisory and enforcement authority and may substantially restrict the
permissible activities of a particular institution if deemed to pose
significant risks to the soundness of such institution or the safety of
the federal deposit insurance fund. Regulatory actions, such as
increases in the minimum capital requirements applicable to banks and
thrifts and increases in deposit insurance premiums required to be paid
by banks and thrifts to the Federal Deposit Insurance Corporation
("FDIC"), can negatively impact earnings and the ability of a company to
pay dividends. Neither federal insurance of deposits nor governmental

Page 2

regulations, however, insures the solvency or profitability of banks or
their holding companies, or insures against any risk of investment in
the securities issued by such institutions.

The statutory requirements applicable to and regulatory supervision of
banks, thrifts and their holding companies have increased significantly
and have undergone substantial change in recent years. To a great
extent, these changes are embodied in the Financial Institutions Reform,
Recovery and Enforcement Act; enacted in August 1989, the Federal
Deposit Insurance Corporation Improvement Act of 1991, the Resolution
Trust Corporation Refinancing, Restructuring, and Improvement Act of
1991 and the regulations promulgated under these laws. Many of the
regulations promulgated pursuant to these laws have only recently been
finalized and their impact on the business, financial condition and
prospects of the Securities in the Trust's portfolio cannot be predicted
with certainty. The recently enacted Gramm-Leach-Bliley Act repealed
most of the barriers set up by the 1933 Glass-Steagall Act which
separated the banking, insurance and securities industries. Now banks,
insurance companies and securities firms can merge to form one-stop
financial conglomerates marketing a wide range of financial service
products to investors. This legislation will likely result in increased
merger activity and heightened competition among existing and new
participants in the field. Efforts to expand the ability of federal
thrifts to branch on an interstate basis have been initially successful
through promulgation of regulations, and legislation to liberalize
interstate banking has recently been signed into law. Under the
legislation, banks will be able to purchase or establish subsidiary
banks in any state, one year after the legislation's enactment. Since
mid-1997, banks have been allowed to turn existing banks into branches.
Consolidation is likely to continue. The Securities and Exchange
Commission and the Financial Accounting Standards Board require the
expanded use of market value accounting by banks and have imposed rules
requiring market accounting for investment securities held in trading
accounts or available for sale. Adoption of additional such rules may
result in increased volatility in the reported health of the industry,
and mandated regulatory intervention to correct such problems.
Additional legislative and regulatory changes may be forthcoming. For
example, the bank regulatory authorities have proposed substantial
changes to the Community Reinvestment Act and fair lending laws, rules
and regulations, and there can be no certainty as to the effect, if any,
that such changes would have on the Securities in the Trust's portfolio.
In addition, from time to time the deposit insurance system is reviewed
by Congress and federal regulators, and proposed reforms of that system
could, among other things, further restrict the ways in which deposited
moneys can be used by banks or reduce the dollar amount or number of
deposits insured for any depositor. Such reforms could reduce
profitability as investment opportunities available to bank institutions
become more limited and as consumers look for savings vehicles other
than bank deposits. Banks and thrifts face significant competition from
other financial institutions such as mutual funds, credit unions,
mortgage banking companies and insurance companies, and increased
competition may result from legislative broadening of regional and
national interstate banking powers as has been recently enacted. Among
other benefits, the legislation allows banks and bank holding companies
to acquire across previously prohibited state lines and to consolidate
their various bank subsidiaries into one unit. The Sponsor makes no
prediction as to what, if any, manner of bank and thrift regulatory
actions might ultimately be adopted or what ultimate effect such actions
might have on the Trust's portfolio.

The Federal Bank Holding Company Act of 1956 generally prohibits a bank
holding company from (1) acquiring, directly or indirectly, more than 5%
of the outstanding shares of any class of voting securities of a bank or
bank holding company, (2) acquiring control of a bank or another bank
holding company, (3) acquiring all or substantially all the assets of a
bank, or (4) merging or consolidating with another bank holding company,
without first obtaining Federal Reserve Board ("FRB") approval. In
considering an application with respect to any such transaction, the FRB
is required to consider a variety of factors, including the potential
anti-competitive effects of the transaction, the financial condition and
future prospects of the combining and resulting institutions, the
managerial resources of the resulting institution, the convenience and
needs of the communities the combined organization would serve, the
record of performance of each combining organization under the Community
Reinvestment Act and the Equal Credit Opportunity Act, and the
prospective availability to the FRB of information appropriate to
determine ongoing regulatory compliance with applicable banking laws. In
addition, the federal Change In Bank Control Act and various state laws
impose limitations on the ability of one or more individuals or other
entities to acquire control of banks or bank holding companies.

The FRB has issued a policy statement on the payment of cash dividends
by bank holding companies. In the policy statement, the FRB expressed
its view that a bank holding company experiencing earnings weaknesses
should not pay cash dividends which exceed its net income or which could
only be funded in ways that would weaken its financial health, such as
by borrowing. The FRB also may impose limitations on the payment of
dividends as a condition to its approval of certain applications,
including applications for approval of mergers and acquisitions. The
Sponsor makes no prediction as to the effect, if any, such laws will
have on the Securities or whether such approvals, if necessary, will be
obtained.

Companies involved in the insurance industry are engaged in
underwriting, reinsuring, selling, distributing or placing of property
and casualty, life or health insurance. Other growth areas within the
insurance industry include brokerage, reciprocals, claims processors and
multiline insurance companies. Insurance company profits are affected by
interest rate levels, general economic conditions, and price and
marketing competition. Property and casualty insurance profits may also

Page 3

be affected by weather catastrophes and other disasters. Life and health
insurance profits may be affected by mortality and morbidity rates.
Individual companies may be exposed to material risks including reserve
inadequacy and the inability to collect from reinsurance carriers.
Insurance companies are subject to extensive governmental regulation,
including the imposition of maximum rate levels, which may not be
adequate for some lines of business. Proposed or potential tax law
changes may also adversely affect insurance companies' policy sales, tax
obligations, and profitability. In addition to the foregoing, profit
margins of these companies continue to shrink due to the commoditization
of traditional businesses, new competitors, capital expenditures on new
technology and the pressures to compete globally.

In addition to the normal risks of business, companies involved in the
insurance industry are subject to significant risk factors, including
those applicable to regulated insurance companies, such as: (i) the
inherent uncertainty in the process of establishing property-liability
loss reserves, particularly reserves for the cost of environmental,
asbestos and mass tort claims, and the fact that ultimate losses could
materially exceed established loss reserves which could have a material
adverse effect on results of operations and financial condition; (ii)
the fact that insurance companies have experienced, and can be expected
in the future to experience, catastrophe losses which could have a
material adverse impact on their financial condition, results of
operations and cash flow; (iii) the inherent uncertainty in the process
of establishing property-liability loss reserves due to changes in loss
payment patterns caused by new claims settlement practices; (iv) the
need for insurance companies and their subsidiaries to maintain
appropriate levels of statutory capital and surplus, particularly in
light of continuing scrutiny by rating organizations and state insurance
regulatory authorities, and in order to maintain acceptable financial
strength or claims-paying ability rating; (v) the extensive regulation
and supervision to which insurance companies' subsidiaries are subject,
various regulatory initiatives that may affect insurance companies, and
regulatory and other legal actions; (vi) the adverse impact that
increases in interest rates could have on the value of an insurance
company's investment portfolio and on the attractiveness of certain of
its products; (vii) the need to adjust the effective duration of the
assets and liabilities of life insurance operations in order to meet the
anticipated cash flow requirements of its policyholder obligations; and
(viii) the uncertainty involved in estimating the availability of
reinsurance and the collectibility of reinsurance recoverables.

The state insurance regulatory framework has, during recent years, come
under increased federal scrutiny, and certain state legislatures have
considered or enacted laws that alter and, in many cases, increase state
authority to regulate insurance companies and insurance holding company
systems. Further, the National Association of Insurance Commissioners
("NAIC") and state insurance regulators are re-examining existing laws
and regulations, specifically focusing on insurance companies,
interpretations of existing laws and the development of new laws. In
addition, Congress and certain federal agencies have investigated the
condition of the insurance industry in the United States to determine
whether to promulgate additional federal regulation. The Sponsor is
unable to predict whether any state or federal legislation will be
enacted to change the nature or scope of regulation of the insurance
industry, or what effect, if any, such legislation would have on the
industry.

All insurance companies are subject to state laws and regulations that
require diversification of their investment portfolios and limit the
amount of investments in certain investment categories. Failure to
comply with these laws and regulations would cause non-conforming
investments to be treated as non-admitted assets for purposes of
measuring statutory surplus and, in some instances, would require
divestiture.

Environmental pollution clean-up is the subject of both federal and
state regulation. By some estimates, there are thousands of potential
waste sites subject to clean up. The insurance industry is involved in
extensive litigation regarding coverage issues. The Comprehensive
Environmental Response Compensation and Liability Act of 1980
("Superfund") and comparable state statutes ("mini-Superfund") govern
the clean-up and restoration by "Potentially Responsible Parties"
("PRP's"). Superfund and the mini-Superfunds ("Environmental Clean-up
Laws or "ECLs") establish a mechanism to pay for clean-up of waste sites
if PRP's fail to do so, and to assign liability to PRP's. The extent of
liability to be allocated to a PRP is dependent on a variety of factors.
The extent of clean-up necessary and the assignment of liability has not
been fully established. The insurance industry is disputing many such
claims. Key coverage issues include whether Superfund response costs are
considered damages under the policies, when and how coverage is
triggered, applicability of pollution exclusions, the potential for
joint and several liability and definition of an occurrence. Similar
coverage issues exist for clean up and waste sites not covered under
Superfund. To date, courts have been inconsistent in their rulings on
these issues. An insurer's exposure to liability with regard to its
insureds which have been, or may be, named as PRPs is uncertain.
Superfund reform proposals have been introduced in Congress, but none
have been enacted. There can be no assurance that any Superfund reform
legislation will be enacted or that any such legislation will provide
for a fair, effective and cost-efficient system for settlement of
Superfund related claims.

While current federal income tax law permits the tax-deferred
accumulation of earnings on the premiums paid by an annuity owner and
holders of certain savings-oriented life insurance products, no
assurance can be given that future tax law will continue to allow such
tax deferrals. If such deferrals were not allowed, consumer demand for
the affected products would be substantially reduced. In addition,
proposals to lower the federal income tax rates through a form of flat

Page 4

tax or otherwise could have, if enacted, a negative impact on the demand
for such products.

Companies engaged in investment banking/brokerage and investment
management include brokerage firms, broker/dealers, investment banks,
finance companies and mutual fund companies. Earnings and share prices
of companies in this industry are quite volatile, and often exceed the
volatility levels of the market as a whole. Recently, ongoing
consolidation in the industry and the strong stock market has benefited
stocks which investors believe will benefit from greater investor and
issuer activity. Major determinants of future earnings of these
companies are the direction of the stock market, investor confidence,
equity transaction volume, the level and direction of long-term and
short-term interest rates, and the outlook for emerging markets.
Negative trends in any of these earnings determinants could have a
serious adverse effect on the financial stability, as well as the stock
prices, of these companies. Furthermore, there can be no assurance that
the issuers of the Securities included in the Trust will be able to
respond in a timely manner to compete in the rapidly developing
marketplace. In addition to the foregoing, profit margins of these
companies continue to shrink due to the commoditization of traditional
businesses, new competitors, capital expenditures on new technology and
the pressures to compete globally.

Healthcare. The Trust also invests in common stocks of companies
involved in advanced medical devices and instruments, drugs and biotech,
healthcare/managed care, hospital management/health services and medical
supplies which have potential risks unique to their sector of the
healthcare field. These companies are subject to governmental regulation
of their products and services, a factor which could have a significant
and possibly unfavorable effect on the price and availability of such
products or services. Furthermore, such companies face the risk of
increasing competition from new products or services, generic drug
sales, the termination of patent protection for drug or medical supply
products and the risk that technological advances will render their
products obsolete. The research and development costs of bringing a drug
to market are substantial, and include lengthy governmental review
processes with no guarantee that the product will ever come to market.
Many of these companies may have losses and may not offer certain
products for several years. Such companies may also have persistent
losses during a new product's transition from development to production,
and revenue patterns may be erratic. In addition, healthcare facility
operators may be affected by events and conditions including among other
things, demand for services, the ability of the facility to provide the
services required, physicians' confidence in the facility, management
capabilities, competition with other hospitals, efforts by insurers and
governmental agencies to limit rates, legislation establishing state
rate-setting agencies, expenses, government regulation, the cost and
possible unavailability of malpractice insurance and the termination or
restriction of governmental financial assistance, including that
associated with Medicare, Medicaid and other similar third party payor
programs.

As the population of the United States ages, the companies involved in
the healthcare field will continue to search for and develop new drugs,
medical products and medical services through advanced technologies and
diagnostics. On a worldwide basis, such companies are involved in the
development and distributions of drugs, vaccines, medical products and
medical services. These activities may make the healthcare and medical
services sector very attractive for investors seeking the potential for
growth in their investment portfolio. However, there are no assurances
that the Trust's objectives will be met.

Legislative proposals concerning healthcare are proposed in Congress
from time to time. These proposals span a wide range of topics,
including cost and price controls (which might include a freeze on the
prices of prescription drugs), national health insurance, incentives for
competition in the provision of healthcare services, tax incentives and
penalties related to healthcare insurance premiums and promotion of pre-
paid healthcare plans. The Sponsor is unable to predict the effect of
any of these proposals, if enacted, on the issuers of Securities in the
Trust.

Technology Companies. Technology companies generally include companies
involved in the development, design, manufacture and sale of computers
and peripherals, software and services, data networking/communications
equipment, internet access/information providers, semiconductors and
semiconductor equipment and other related products, systems and
services. The market for these products, especially those specifically
related to the Internet, is characterized by rapidly changing
technology, rapid product obsolescence, cyclical market patterns,
evolving industry standards and frequent new product introductions. The
success of the issuers of the Securities depends in substantial part on
the timely and successful introduction of new products. An unexpected
change in one or more of the technologies affecting an issuer's products
or in the market for products based on a particular technology could
have a material adverse effect on an issuer's operating results.
Furthermore, there can be no assurance that the issuers of the
Securities will be able to respond in a timely manner to compete in the
rapidly developing marketplace.

Based on trading history of common stock, factors such as announcements
of new products or development of new technologies and general
conditions of the industry have caused and are likely to cause the
market price of high-technology common stocks to fluctuate
substantially. In addition, technology company stocks have experienced
extreme price and volume fluctuations that often have been unrelated to
the operating performance of such companies. This market volatility may
adversely affect the market price of the Securities and therefore the
ability of a Unit holder to redeem Units at a price equal to or greater
than the original price paid for such Units.

Some key components of certain products of technology issuers are
currently available only from single sources. There can be no assurance

Page 5

that in the future suppliers will be able to meet the demand for
components in a timely and cost effective manner. Accordingly, an
issuer's operating results and customer relationships could be adversely
affected by either an increase in price for, or an interruption or
reduction in supply of, any key components. Additionally, many
technology issuers are characterized by a highly concentrated customer
base consisting of a limited number of large customers who may require
product vendors to comply with rigorous industry standards. Any failure
to comply with such standards may result in a significant loss or
reduction of sales. Because many products and technologies of technology
companies are incorporated into other related products, such companies
are often highly dependent on the performance of the personal computer,
electronics and telecommunications industries. There can be no assurance
that these customers will place additional orders, or that an issuer of
Securities will obtain orders of similar magnitude as past orders from
other customers. Similarly, the success of certain technology companies
is tied to a relatively small concentration of products or technologies.
Accordingly, a decline in demand of such products, technologies or from
such customers could have a material adverse impact on issuers of the
Securities.

Many technology companies rely on a combination of patents, copyrights,
trademarks and trade secret laws to establish and protect their
proprietary rights in their products and technologies. There can be no
assurance that the steps taken by the issuers of the Securities to
protect their proprietary rights will be adequate to prevent
misappropriation of their technology or that competitors will not
independently develop technologies that are substantially equivalent or
superior to such issuers' technology. In addition, due to the increasing
public use of the Internet, it is possible that other laws and
regulations may be adopted to address issues such as privacy, pricing,
characteristics, and quality of Internet products and services. The
adoption of any such laws could have a material adverse impact on the
Securities in the Trust.

Like many areas of technology, the semiconductor business environment is
highly competitive, notoriously cyclical and subject to rapid and often
unanticipated change. Recent industry downturns have resulted, in part,
from weak pricing, persistent overcapacity, slowdown in Asian demand and
a shift in retail personal computer sales toward the low end, or "sub-
$1,000" segment. Industry growth is dependent upon several factors,
including: the rate of global economic expansion; demand for products
such as personal computers and networking and communications equipment;
excess productive capacity and the resultant effect on pricing; and the

                           Re:  FT 666

     The  only  difference  of consequence (except  as  described
below) between FT 700, which is the current fund, and FT 666, the
filing of which this memorandum accompanies, is the change in the
series  number.  The list of securities comprising the Fund,  the
evaluation,  record  and  distribution dates  and  other  changes
pertaining  specifically  to the new series,  such  as  size  and
number of Units in the Fund and the statement of condition of the
new Fund, will be filed by amendment.

                      FORMS N-8A AND N-8B-2

     These forms were not filed, as the Form N-8A and Form N-8B-2
filed in respect of Templeton Growth and Treasury Trust, Series 1
and  subsequent series (File No. 811-05903) related also  to  the
subsequent series of the Fund.

                           PROSPECTUS

     The  only  significant changes in the  Prospectus  from  the
Series  700 Prospectus relate to the series number and  size  and
the  date and various items of information which will be  derived
from  and apply specifically to the securities deposited  in  the
Fund.
