If we make such an adjustment, the fractional undivided interest per Unit will vary from the amount indicated above. (2) Each listed Security is valued at its last closing sale price. If a 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"). (3) The maximum transactional sales charge consists of an initial sales charge and a deferred sales charge, but does not include the creation and development fee. See "Fee Table" and "Public Offering." (4) 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 Securities. After this date, a pro rata share of any accumulated dividends on the Securities will be included. (5) 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 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 estimated organization costs. See "Redeeming Your Units." (6) See "Amending or Terminating the Indenture." (7) At the Rollover Notification Date for Rollover Unit holders or upon termination of the Trust for Remaining Unit holders, amounts in the Income Account (which consist of dividends on the Securities) will be included in amounts distributed to Unit holders. We will distribute money from the Capital Account 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, we will distribute any funds in the Capital Account in December of each year. </FN> Page 3 Fee Table 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 15 months and is a unit investment trust rather than a mutual fund, this information allows you to compare fees. Amount per Unit _____ Unit Holder Sales Fees (as a percentage of public offering price) Maximum Sales Charge Initial sales charge 1.00%(a) $.100 Deferred sales charge 1.65%(b) $.165 Creation and development fee cap over the life of the Trust 0.30%(c) $.030 _______ _______ (the annual creation and development fee is .30% of average daily net assets for the Trust, and is only charged while a Unit holder remains invested) Maximum Sales Charges (including creation and development fee cap over the life of the Trust) (c) 2.95% $.295 ======= ======= Organization Costs (as a percentage of public offering price) Estimated organization costs %(d) $ ======= ======= Estimated Annual Trust Operating Expenses(e) (as a percentage of average net assets) Portfolio supervision, bookkeeping, administrative and evaluation fees % $ Trustee's fee and other operating expenses %(f) $ _______ _______ Total % $ ======= ======= 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 sell all your Units at the end of those periods. The example also assumes a 5% return on your investment each year and that the 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 ______ _______ _______ ________ $ $ $ $ The example assumes that the principal amount and distributions are rolled annually into a New Trust, and you are subject to a reduced transactional sales charge. ________________ <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 transactional sales charge of 2.65% and any remaining deferred sales charge. (b) The deferred sales charge is a fixed dollar amount equal to $.165 per Unit which, as a percentage of the Public Offering Price, will vary over time. The deferred sales charge will be deducted in ten monthly installments commencing July 20, 2001. (c) The creation and development fee compensates the Sponsor for creating and developing the Trust. For as long as you own Units, this fee will be accrued daily based on the Trust's net asset value at the annual rate of .30%. You will only be charged the creation and development fee while you own Units. The Trust pays the amount of any accrued creation and development fee to the Sponsor monthly from the Trust's assets. Because the creation and development fee is accrued daily on the basis of the Trust's current net asset value, if the value of your Units increases, the annual creation and development fee as a percentage of your initial investment would be greater than .30%. However, in no event will we collect over the life of the Trust more than .30% of your initial investment. (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 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." </FN> Page 4 Report of Independent Auditors The Sponsor, Nike Securities L.P., and Unit Holders FT 507 We have audited the accompanying statement of net assets, including the schedule of investments, of FT 507, comprised of the Fifth Third's Best 2001 Series, as of the opening of business on March __, 2001. 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. 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 letter of credit held by the Trustee and deposited in the Trust on March __, 2001. An audit also includes assessing the accounting principles used and significant estimates made by the 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 507, comprised of the Fifth Third's Best 2001 Series, at the opening of business on March __, 2001 in conformity with accounting principles generally accepted in the United States.

(2) An irrevocable letter of credit issued by The Chase Manhattan 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 $ per Unit for the Trust. A payment will be made as of 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 of the Trust 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 from the Trust ($.165 per Unit), payable to us in ten equal monthly installments beginning on July 20, 2001 and on the twentieth day of each month thereafter (or if such date is not a business day, on the preceding business day) through April 19, 2002. If you redeem Units before April 19, 2002 you will have to pay the remaining amount of the deferred sales charge applicable to such Units when you redeem them. (5) The aggregate cost to investors in the Trust includes a maximum transactional sales charge (comprised of an initial and a deferred sales charge) computed at the rate of 2.65% of the Public Offering Price per Unit (equivalent to 2.677% of the net amount invested, exclusive of the deferred sales charge), assuming no reduction of the transactional sales charge as set forth under "Public Offering." </FN> Page 6 Schedule of Investments Fifth Third's Best 2001 Series FT 507 At the Opening of Business on the Initial Date of Deposit-March __, 2001 Percentage Market Cost of Number Ticker Symbol and of Aggregate Value per Securities to of Shares Name of Issuer of Securities (1) (3) Offering Price Share the Trust (2) _____ ____________________________________ ______________ ______ _____________ AXTI AXT, Inc. % $ $ AIG American International Group, Inc. % AMGN Amgen Inc. % ADI Analog Devices, Inc. % ADP Automatic Data Processing, Inc. % BMET Biomet, Inc. % CSCO Cisco Systems, Inc. % CMVT Comverse Technology, Inc. % COC/B Conoco Inc.

We entered into purchase contracts for the Securities on March __, 2001. The Trust has a mandatory termination date of June 26, 2002. (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 Securities and the ask prices of the over-the-counter traded Securities at the Evaluation Time on the business day preceding the Initial Date of Deposit). The valuation of the Securities has been determined by the Evaluator, an affiliate of ours. The cost of the Securities to us and our profit or loss (which is the difference between the cost of the Securities to us and the cost of the Securities to the Trust) are $ and $ , respectively. (3) The final portfolio may contain additional Securities to those set forth above. In addition, although it is not the Sponsor's intention, certain of the Securities listed above may not be included in the final portfolio. (4) This Security represents the common stock of a foreign company which trades directly on a U.S. national securities exchange. </FN> Page 7 The FT Series The FT Series Defined. We, Nike Securities 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 the prospectus relates, FT 507, consists of a single portfolio known as Fifth Third's Best 2001 Series. 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 Nike Securities L.P., as Sponsor, The Chase Manhattan 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 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 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 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 objective of the Trust is to provide the potential for above-average capital appreciation by investing in a diversified portfolio of common stocks of companies which have been selected by the Investment Advisors of Fifth Third Bank ("Fifth Third"). The stocks chosen are those Fifth Page 8 Third's analysts believe investors should own over the next year to achieve growth potential. It is Fifth Third's belief that the stocks chosen will perform well in the upcoming market environment. The 2000 market can best be described as "turbulent." What began as a positive year in the stock market ended with most of the sectors of the market down. Many investors are now wondering where they should be invested to achieve growth potential in their investment portfolios. Fifth Third believes a portfolio chosen by experts, who have spent years studying the market, economic factors and the thousands of companies available to invest in, can give investors the best opportunity for meeting their financial objectives. The Research Method. Fifth Third Investment Advisors adheres to a bottoms up, consistent quality growth investment style of equity investing. Fundamental analysis using both quantitative and qualitative metrics are the foundation of the Fifth Third equity research approach. The methodology identifies and supports high quality, high growth equity investments for clients. Fifth Third seeks exposure to companies that have demonstrated consistency and growth in revenues, cash flows, dividends and earnings over a complete economic cycle. Quantitative outperformance against the relevant market indexes, coupled with a high degree of customer service, is Fifth Third's professional objective. The Portfolio. In selecting the Fifth Third's Best, 2001 Series, the Investment Advisors of Fifth Third Bank identified companies which, in their opinion, satisfied the following criteria: - - Each company selected is an industry leader in its specific business niche. - - Growth rates and profitability metrics are high, and valuation metrics are attractive. - - All companies selected have demonstrated consistent quality growth features. - - Market capitalization includes both large- and mid-cap companies. The equity research function is performed by the Fifth Third Equity Research Staff, a team of seven professionals, each with a sector specific focus. The Team has significant on-line informational assets, extensive Wall Street contacts and over 75 years of combined relevant investment experience. Company visits, management interviews and industry conference attendance, compliment Fifth Third's in-house modeling, qualitative evaluation and quantitative valuation methodology. There is, of course, no guarantee that the objective of the Trust will be achieved. To achieve the goal of tax efficiency with respect to gains, Units should be held more than one year. Investors will recognize gain or loss upon the Trust's termination in approximately 15 months. See "Risk Factors" for a discussion of the risks of investing in the Trust. Risk Factors Price Volatility. The Trust invests in common stocks. The value of the Trust's Units will fluctuate with changes in the value of these 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, 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. Because the Trust is not managed, the Trustee will not sell stocks 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, especially the relatively short 15-month life of the Trust, 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. Certain of the Securities in the Trust are issued by companies with market capitalizations of less than $2 billion. The share prices of these small-cap companies are often more volatile than those of larger companies as a result of several factors common to many such issuers, including limited trading volumes, products or financial resources, management inexperience and less publicly available information. Dividends. There is no guarantee that the issuers of the Securities will declare dividends in the future or that if declared they will either remain at current levels or increase over time. Energy Industry. Because more than 25% of the Trust is invested in companies that explore for, produce, refine, distribute or sell Page 9 petroleum or gas products, or provide parts or services to petroleum or gas companies, the Trust is considered to be concentrated in the energy industry. A portfolio concentrated in a single industry may present more risks than a portfolio which is broadly diversified over several industries. General problems of the petroleum and gas products industry include volatile fluctuations in price and supply of energy fuels, international politics, reduced demand as a result of increases in energy efficiency and energy conservation, the success of exploration projects, clean-up and litigation costs relating to oil spills and environmental damage, and tax and other regulatory policies of various governments. Oil production and refining companies are subject to extensive federal, state and local environmental laws and regulations regarding air emissions and the disposal of hazardous materials. In addition, declines in U.S. and Russian crude oil production will likely lead to a greater world dependence on oil from OPEC nations which may result in more volatile oil prices. Technology Industry. The Trust is also considered to be concentrated in technology stocks. 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. In addition, litigation regarding any of the issuers of the Securities, such as that concerning Microsoft Corporation, or of the industries represented by these issuers, may negatively impact the share prices of these Securities. 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. One of the Securities in the Trust is issued by a foreign company, which makes the Trust subject to more risks than if it invested solely in domestic common stocks. This Security is directly 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.

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 underlying value of the Securities; - - The amount of any cash in the Income and Capital Accounts; - - Dividends receivable on Securities; and - - The maximum transactional sales charge (which combines an initial up- front sales charge and a deferred sales charge). 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. 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 Securities contained in the Trust. 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 Securities. To the extent the proceeds from the sale of these Securities are insufficient to repay the Sponsor for the Trust organization costs, the Trustee will sell additional Securities to allow the Trust to fully reimburse the Sponsor. In that event, the net asset value per Unit will be reduced by the amount of additional 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 for the Trust in "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 Securities are sold to reimburse the Sponsor for organization costs, the Trustee will sell such Securities, to the extent practicable, which will maintain the same proportionate relationship among the Securities contained in the Trust as existed prior to such sale. Minimum Purchase. The minimum amount you can purchase of the Trust is $2,000 worth of Units. Page 12 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 transactional sales charge of 2.65% of the Public Offering Price and the maximum remaining deferred sales charge (initially $.165 per Unit). This initial sales charge is initially equal to approximately 1.00% of the Public Offering Price of a Unit, but will vary from 1.00% depending on the purchase price of your Units and as deferred sales charge payments are made. When the Public Offering Price per Unit exceeds $10.00, the initial sales charge will exceed 1.00% of the Public Offering Price. Monthly Deferred Sales Charge. In addition, ten monthly deferred sales charge payments of $.0165 per Unit will be deducted from the Trust's assets on approximately the twentieth day of each month from July 20, 2001 through April 19, 2002. If you buy Units at a price of less than $10.00 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 1.65% 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 2.65% of the Public Offering Price (equivalent to 2.677% of the net amount invested). Discounts for Certain Persons. If you invest at least $50,000 (except if you are purchasing for a "wrap fee account" as described below), the maximum transactional sales charge is reduced, as follows: Your maximum transactional If you invest sales charge (in thousands)* will be _______________ ____________ $50 but less than $100 2.40% $100 but less than $150 2.15% $150 but less than $500 1.80% $500 but less than $1,000 1.65% $1,000 or more 0.90% * Breakpoint transactional 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 transactional sales charge for quantity purchases will apply only to purchases made by the same person on any one day from any one dealer or selling agent. 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 for the purpose of reaching the above levels. You must inform your dealer of any combined purchases before the sale in order to be eligible for the reduced transactional sales charge. Any reduced transactional sales charge is the responsibility of the party making the sale. 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, your Units will only be assessed that portion of the transactional sales charge retained by the Sponsor, 0.40% of the Public Offering Price. See "Distributions of Units-Concessions." 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. The following persons may purchase Units at the Public Offering Price less the applicable dealer concession: - - Employees, officers and directors of the Sponsor, our related companies, vendors providing services to us and brokers of Fifth Third Securities, Inc. - - Immediate family members of the above (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). - - Trust clients of Fifth Third Bank, except for purchases made for a 401(k) account. For employees, officers and directors of Fifth Third Bancorp and Fifth Third Securities, Inc., their affiliates, and immediate family members of such persons as described above, the sales charge is reduced by 1.75% of the Public Offering Price. 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 Page 13 the maximum transactional sales charge you must pay is less than the applicable maximum deferred sales charge, you will be credited the difference between your maximum transactional 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 Securities will be determined as follows: if the 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 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 is generally determined: a) On the basis of current ask prices for comparable securities; b) By appraising the value of the 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 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. Concessions. Fifth Third Securities, Inc., a wholly-owned non-banking subsidiary of Fifth Third Bancorp, is making Units of the Trust available to their customers on an agency basis. Selling agents of Fifth Third Securities, Inc., or of any securities firm subsequently acquired by Fifth Third Bancorp, can purchase Units at prices which reflect a concession or agency commission of 2.25% of the Public Offering Price per Unit. However, for Units subject to a transactional sales charge which are purchased using redemption or termination proceeds or on purchases by Rollover Unit holders, this amount will be reduced to 1.3% of the sales price of these Units (0.5% for Rollover purchases of $1,000,000 or more). If Fifth Third Securities, Inc. sells Units of the Trust during the initial offering period in the dollar amounts shown below, they will be entitled to the following additional agency commissions as a percentage of the Public Offering Price: Total Sales Additional (in millions): Commissions: _______________ ____________ $1 but less than $3 0.05% $3 but less than $5 0.10% $5 but less than $15 0.15% $15 or more 0.20% Dealers and other selling agents will not receive a concession on the sale of Units which are not subject to the transactional sales charge, but such Units will be included in determining whether the above volume sales levels are met. Dealers and other selling agents who, during any Page 14 consecutive 12-month period, sell at least $1.75 billion worth of primary market units of unit investment trusts sponsored by us will receive a concession of $30,000 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. Investment Comparisons. 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. The Sponsor's Profits We will receive a gross sales commission equal to the maximum transactional sales charge per Unit of the Trust less any reduction as stated in "Public Offering." We will also receive the amount of any accrued and 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 "Schedule of Investments"). During the initial offering period, dealers and others may also realize profits or sustain losses as a result of fluctuations in the Public Offering Price they receive when they sell the Units. In maintaining a market for the 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. 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 that 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 Page 15 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. The Trustee will pay operating expenses of the Trust from the Income Account 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. As Sponsor, we will be compensated for providing bookkeeping and other administrative services to the Trust, and will receive brokerage fees when the Trust uses us (or an affiliate of ours) as agent in buying or selling Securities. First Trust Advisors L.P., an affiliate of ours, acts as both Portfolio Supervisor and Evaluator to the Trust and will receive the fees set forth under "Fee Table" for providing portfolio supervisory and evaluation services to the Trust. In providing portfolio supervisory services, the Portfolio Supervisor will purchase research services from a number of sources, which may include dealers and other selling agents of the Trust. The fees payable to us, 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 a given service to all unit investment trusts for which we provide such services be more than the actual cost of providing such services in such year. As Sponsor, we will receive a fee from the Trust for creating and developing the Trust, including determining the Trust 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 accrued (and becomes a liability of the Trust) on a daily basis. The dollar amount of the creation and development fee accrued each day, which will vary with fluctuations in the Trust's net asset value, is determined by multiplying the net asset value of the Trust on that day by 1/365 of the annual creation and development fee of .30%. The total amount of any accrued but unpaid creation and development fee is paid to the Sponsor on a monthly basis from the assets of the Trust. If you redeem your Units, you will only be responsible for any accrued and unpaid creation and development fee through the date of redemption. In connection with the creation and development fee, in no event will the Sponsor collect over the life of the Trust more than .30% of a Unit holder's initial investment. We do not use this fee to pay distribution expenses or as compensation for sales efforts. In addition to the Trust's operating expenses and those fees described above, the Trust may also incur the following charges: - - All legal 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 the Securities are all common stocks and dividend income 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." 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 Page 16 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 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. 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 Securities and other assets held by the Trust, and as such you will be considered to have received a pro rata share of income (i.e., dividends and capital gains, if any) from each Security when such income is considered to be received by the Trust. This is true even if you elect to have your distributions automatically reinvested into additional Units. In addition, the income from the Trust 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 the Trust disposes of Securities, 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 Securities from your share of the total amount received in the transaction. You can generally determine your initial tax basis in each Security or other Trust asset by apportioning the cost of your Units, generally including sales charges, among each Security or other 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 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 lowest tax bracket). For tax years beginning after December 31, 2000, the 20% rate is reduced to 18% and the 10% rate is reduced to 8% for long-term gains from most property with a holding period of more than five years. Because the Trust has a maturity of approximately 15 months, the reduction of the capital gains rate for property held for more than five years could only possibly apply to your interest in the Securities if you are eligible for and elect to receive an in-kind distribution at redemption or termination. 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 the holding period of your Units. 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 may, however, treat certain capital gains as ordinary income in special situations. Rollovers. If you elect to have your proceeds from the Trust rolled over into the next series of the Trust, it is considered a sale for federal income tax purposes, and any gain on the sale will be treated as a capital gain, and any loss will be treated as a capital loss. However, any loss you incur in connection with the exchange of your Units of the Trust for units of the next series will generally be disallowed with respect to this deemed sale and subsequent deemed repurchase, to the extent the two trusts have substantially identical Securities under the wash sale provisions of the Internal Revenue Code. In-Kind Distributions. Under certain circumstances, you may request a distribution of Securities (an "In-Kind Distribution") when you redeem your Units or at the Trust's termination. If you request an In-Kind Distribution you will be responsible for any expenses related to this distribution. By electing to receive an In-Kind Distribution, you will receive whole shares of stock plus, possibly, cash. You will not recognize gain or loss if you only receive Securities in exchange for your pro rata portion of the Securities held by the Trust. Page 17 However, if you also receive cash in exchange for a fractional share of a Security held by the Trust, you will generally recognize gain or loss based on the difference between the amount of cash you receive and your tax basis in such fractional share of the Security. 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. 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; - - A list of the number of Units issued or transferred; Page 18 - - 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. 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 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. 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. Within a reasonable time after the Trust is terminated, unless you are a Rollover Unit holder, you will receive the 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 or 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. 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 Page 19 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 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 it does not have your TIN, as generally discussed under "Income and Capital Distributions." If you tender 1,000 Units or more 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, 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 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 Securities that make up the portfolio, and cash from the Capital Account equal to the fractional shares to which you are entitled. The Trustee may sell Securities to make funds available for redemption. 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 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; 5. liquidation costs for foreign Securities, if any; and 6. 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 Page 20 the initial offering period, the Redemption Price per Unit will include estimated organization costs as set forth under "Fee Table." Investing in a New Trust The Trust's portfolio has been selected on the basis of capital appreciation potential for a limited time period. When the Trust is about to terminate, you may have the option to roll your proceeds into the next series of the Trust (the "New Trust") if one is available. We intend to create the New Trust in conjunction with the termination of the Trust and plan to use the same procedure we used to select the portfolio for the Trust to the New Trust. If you wish to have the proceeds from your Units rolled into the New Trust you must notify the Trustee in writing of your election by the Rollover Notification Date stated in the "Summary of Essential Information." As a Rollover Unit holder, your Units will be redeemed and the underlying Securities sold by the Trustee, in its capacity as Distribution Agent, during the Special Redemption and Liquidation Period. The Distribution Agent may engage us or other brokers as its agent to sell the Securities. Once all of the Securities are sold, your proceeds, less any brokerage fees, governmental charges or other expenses involved in the sales, will be used to buy units of the New Trust or trust with a similar investment strategy that you have selected, provided such trusts are registered and being offered. Accordingly, proceeds may be uninvested for up to several days. Units purchased with rollover proceeds will generally be purchased subject to the maximum remaining deferred sales charge on such units (currently expected to be $.165 per unit), but not the initial sales charge. Units purchased using proceeds from Fee Accounts Units will generally not be subject to any transactional sales charge. We intend to create New Trust units as quickly as possible, depending on the availability of the Securities contained in the New Trust's portfolio. Rollover Unit holders will be given first priority to purchase New Trust units. We cannot, however, assure the exact timing of the creation of New Trust units or the total number of New Trust units we will create. Any proceeds not invested on behalf of Rollover Unit holders in New Trust units will be distributed within a reasonable time after such occurrence. Although we believe that enough New Trust units can be created, monies in the New Trust may not be fully invested on the next business day. Please note that there are certain tax consequences associated with becoming a Rollover Unit holder. See "Tax Status." If you elect not to participate as a Rollover Unit holder ("Remaining Unit holders"), you will not incur capital gains or losses due to the Special Redemption and Liquidation, nor will you be charged any additional sales charge. We may modify, amend or terminate this rollover option upon 60 days notice. 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 a Security in certain limited circumstances, including situations in which: - - The issuer of the 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 the Security; - - The issuer of the 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 the Security; - - The issuer has defaulted on the payment of any other of its outstanding obligations; - - There has been a public tender offer made for a Security or a merger or acquisition is announced affecting a Security, and that in our opinion the sale or tender of the Security is in the best interest of Unit holders; or - - The price of the Security has declined to such an extent, or such other credit factors exist, that in our opinion keeping the 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 Page 21 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. 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 which 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 as stated in the "Summary of Essential Information." The Trust may be terminated earlier: - - Upon the consent of 100% of the Unit holders; - - If the value of the Securities owned by the Trust as shown by any evaluation is less than the lower of $2,000,000 or 20% of the total value of Securities deposited in the Trust during the initial offering period ("Discretionary Liquidation Amount"); 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. For various reasons, including Unit holders' participation as Rollover Unit holders, the Trust may be reduced below the Discretionary Liquidation Amount and could therefore be terminated before the Mandatory Termination Date. Unless terminated earlier, the Trustee will begin to sell 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 Securities. Because the Trustee must sell the Securities within a relatively short period of time, the sale of 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. If you own at least 1,000 Units of the Trust the Trustee will send you a form at least 30 days prior to the Mandatory Termination Date which will enable you to receive an In-Kind Distribution of Securities (reduced by customary transfer and registration charges) rather than the typical cash distribution. See "Tax Status" for additional information. 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 either the Rollover Option or 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 your Trust is terminated. Regardless of the distribution involved, the Trustee will deduct from the Trust any accrued costs, expenses, advances or Page 22 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.

This Information Supplement is not a prospectus and does not include all of the information you should consider before investing in the Trust. This Information Supplement should be read in conjunction with the prospectus for the Trust in which you are considering investing. This Information Supplement is dated March __, 2001. Capitalized terms have been defined in the prospectus. Table of Contents Risk Factors Securities 1 Small-Cap Companies 1 Dividends 1 Foreign Issuers 1 Litigation Microsoft Corporation 2 Concentrations Energy 2 Technology Companies 3 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. Small-Cap Companies. While historically small-cap company stocks have outperformed the stocks of large companies, the former have customarily involved more investment risk as well. Small-cap companies may have limited product lines, markets or financial resources; may lack management depth or experience; and may be more vulnerable to adverse general market or economic developments than large companies. Some of these companies may distribute, sell or produce products which have recently been brought to market and may be dependent on key personnel. The prices of small company securities are often more volatile than prices associated with large company issues, and can display abrupt or erratic movements at times, due to limited trading volumes and less publicly available information. Also, because small cap companies normally have fewer shares outstanding and these shares trade less frequently than large companies, it may be more difficult for the Trust to buy and sell significant amounts of such shares without an unfavorable impact on prevailing market prices. 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. 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. Litigation Microsoft Corporation. Microsoft Corporation is currently engaged in litigation with the U.S. Department of Justice and several state Attorneys General. The complaints against Microsoft include unfair competition and anti-trust violations. The claims seek injunctive relief and monetary damages. The District Court handling the antitrust case recently held that Microsoft exercised monopoly power in violation of the Sherman Antitrust Act and various state antitrust laws. The court entered into a final judgment on June 7, 2000 in which it called for Microsoft to be broken up into two separate companies, one composed of the company's operating systems and the other containing its applications software business. The court also called for significant operating restrictions to be placed on the company until such time as the separation was completed. Microsoft has stated that it will appeal the rulings against it after the penalty phase and final decree. It is impossible to predict what impact the penalties will have on Microsoft or the value of its stock. Concentrations Energy. An investment in Units of the Trust should be made with an understanding of the problems and risks an investment in Securities of companies involved in the energy industry may entail. The business activities of companies held in the Trust may include: production, generation, transmission, marketing, control, or measurement of gas and oil; the provision of component parts or services to companies engaged in the above activities; energy research or experimentation; and environmental activities related to the solution of energy problems, such as energy conservation and pollution control. The securities of companies in the energy field are subject to changes in value and dividend yield which depend, to a large extent, on the price and supply of energy fuels. Swift price and supply fluctuations Page 2 may be caused by events relating to international politics, energy conservation, the success of exploration projects, and tax and other regulatory policies of various governments. As a result of the foregoing, the Securities in the Energy Portfolios may be subject to rapid price volatility. The Sponsor is unable to predict what impact the foregoing factors will have on the Securities during the life of the Trust. According to the U.S. Department of Commerce, the factors which will most likely shape the energy industry include the price and availability of oil from the Middle East, changes in U.S. environmental policies and the continued decline in U.S. production of crude oil. Possible effects of these factors may be increased U.S. and world dependence on oil from the Organization of Petroleum Exporting Countries ("OPEC") and highly uncertain and potentially more volatile oil prices. Factors which the Sponsor believes may increase the profitability of oil and petroleum operations include increasing demand for oil and petroleum products as a result of the continued increases in annual miles driven and the improvement in refinery operating margins caused by increases in average domestic refinery utilization rates. The existence of surplus crude oil production capacity and the willingness to adjust production levels are the two principal requirements for stable crude oil markets. Without excess capacity, supply disruptions in some countries cannot be compensated for by others. Surplus capacity in Saudi Arabia and a few other countries and the utilization of that capacity prevented, during the Persian Gulf crisis, and continues to prevent, severe market disruption. Although unused capacity contributed to market stability in 1990 and 1991, it ordinarily creates pressure to overproduce and contributes to market uncertainty. The restoration of a large portion of Kuwait and Iraq's production and export capacity could lead to such a development in the absence of substantial growth in world oil demand. Formerly, OPEC members attempted to exercise control over production levels in each country through a system of mandatory production quotas. Because of the 1990-1991 crisis in the Middle East, the mandatory system has since been replaced with a voluntary system. Production under the new system has had to be curtailed on at least one occasion as a result of weak prices, even in the absence of supplies from Kuwait and Iraq. The pressure to deviate from mandatory quotas, if they are reimposed, is likely to be substantial and could lead to a weakening of prices. In the longer term, additional capacity and production will be required to accommodate the expected large increases in world oil demand and to compensate for expected sharp drops in U.S. crude oil production and exports from the Soviet Union. Only a few OPEC countries, particularly Saudi Arabia, have the petroleum reserves that will allow the required increase in production capacity to be attained. Given the large-scale financing that is required, the prospect that such expansion will occur soon enough to meet the increased demand is uncertain. Declining U.S. crude oil production will likely lead to increased dependence on OPEC oil, putting refiners at risk of continued and unpredictable supply disruptions. Increasing sensitivity to environmental concerns will also pose serious challenges to the industry over the coming decade. Refiners are likely to be required to make heavy capital investments and make major production adjustments in order to comply with increasingly stringent environmental legislation, such as the 1990 amendments to the Clean Air Act. If the cost of these changes is substantial enough to cut deeply into profits, smaller refiners may be forced out of the industry entirely. Moreover, lower consumer demand due to increases in energy efficiency and conservation, gasoline reformulations that call for less crude oil, warmer winters or a general slowdown in economic growth in this country and abroad could negatively affect the price of oil and the profitability of oil companies. No assurance can be given that the demand for or prices of oil will increase or that any increases will not be marked by great volatility. Some oil companies may incur large cleanup and litigation costs relating to oil spills and other environmental damage. Oil production and refining operations are subject to extensive federal, state and local environmental laws and regulations governing air emissions and the disposal of hazardous materials. Increasingly stringent environmental laws and regulations are expected to require companies with oil production and refining operations to devote significant financial and managerial resources to pollution control. General problems of the oil and petroleum products industry include the ability of a few influential producers to significantly affect production, the concomitant volatility of crude oil prices, increasing public and governmental concern over air emissions, waste product disposal, fuel quality and the environmental effects of fossil-fuel use in general. In addition, any future scientific advances concerning new sources of energy and fuels or legislative changes relating to the energy industry or the environment could have a negative impact on the petroleum products industry. While legislation has been enacted to deregulate certain aspects of the oil industry, no assurances can be given that new or additional regulations will not be adopted. Each of the problems referred to could adversely affect the financial stability of the issuers of any petroleum industry stocks in the Trust. Technology Companies. The Trust is also considered to be concentrated in common stocks of 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 Page 3 affecting an issuer's products or in the market for products based on a particular technology could have a material adverse affect 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 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 rate of growth in the market for low-priced personal computers.
