'08 FT 1664 FT 1664 is a series of a unit investment trust, the FT Series. FT 1664 consists of a single portfolio known as Pioneer Apr. '08 (the "Trust"). The Trust invests in a diversified portfolio of common stocks ("Common Stocks"), closed-end investment companies ("Closed-End Funds") and Canadian Income and/or Royalty Trusts ("CITs"). Collectively, the Common Stocks, Closed- End Funds and CITs are referred to as the "Securities." Certain of the Closed-End Funds invest in high-yield securities. See "Risk Factors" for a discussion of the risk of investing in high-yield securities or "junk" bonds. The Trust seeks to provide the potential for a high rate of current monthly income and the potential for growth of principal. THE SECURITIES AND EXCHANGE COMMISSION HAS NOT APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

First Settlement Date April 14, 2008 Mandatory Termination Date (7) April 9, 2010 Distribution Record Date Tenth day of each month, commencing May 10, 2008. Distribution Date (6) Twenty-fifth day of each month, commencing May 25, 2008. ______________ (1) As of the close of business on the Initial Date of Deposit, we may adjust the number of Units of the Trust so that the Public Offering Price per Unit will equal approximately $10.00. If we make such an adjustment, the fractional undivided interest per Unit will vary from the amount indicated above. (2) 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 cash in the Income Account. After this date, a pro rata share of any cash in the Income Account will be included. (3) You will pay a maximum sales charge of 3.95% of the Public Offering Price per Unit (equivalent to 3.99% of the net amount invested) which consists of an initial sales charge, a deferred sales charge and a creation and development fee. The sales charges are described in the "Fee Table." (4) 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"). (5) The creation and development fee will be deducted from the assets of the Trust at the end of the initial offering period and the estimated organization costs per Unit 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. If Units are redeemed prior to any such reduction, these fees will not be deducted from the redemption proceeds. See "Redeeming Your Units." (6) The estimated net annual distribution for subsequent years, $.9155 per Unit, is expected to be less than that set forth above for the first year because a portion of the Securities included in the Trust will be sold during the first year to pay for organization costs, the deferred sales charge and the creation and development fee. We base our estimate of the dividends the Trust will receive from the Securities by annualizing the most recent dividends declared by the issuers of the Securities (such figure adjusted to reflect any change in dividend policy announced subsequent to the most recently declared dividend). 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. Due to this, and various other factors, actual dividends received from the Securities may be less than their most recent annualized dividends. In this case, the actual net annual distribution you receive will be less than the estimated amount set forth above. The actual net annual distribution per Unit you receive will also vary from that set forth above with changes in the Trust's fees and expenses and with the sale of Securities. See "Fee Table" and "Expenses and Charges." The Trustee will distribute money from the Income and Capital Accounts, as determined at the monthly Record Date, monthly on the twenty-fifth day of each month to Unit holders of record on the tenth day of such month provided the aggregate amount, exclusive of sale proceeds, in the Income and Capital Accounts available for distribution equals at least 0.1% of the net asset value of the Trust. Undistributed money in the Income and Capital Accounts will be distributed in the next month in which the aggregate amount available for distribution, exclusive of sale proceeds, equals or exceeds 0.1% of the net asset value of the Trust. Distributions of sale proceeds from the Capital Account will be made monthly on the twenty-fifth day of the month to Unit holders of record on the tenth day of such month if the amount available for distribution equals at least $1.00 per 100 Units. See "Income and Capital Distributions." (7) See "Amending or Terminating the Indenture."
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 two years and is a unit investment trust rather than a mutual fund, this information allows you to compare fees.

The example assumes that you invest $10,000 in the Trust for the periods shown and sell your Units at the end of those periods. The example also assumes a 5% return on your investment each year and that the Trust's operating expenses stay the same. The example does not take into consideration transaction fees which may be charged by certain broker/dealers for processing redemption requests. Although your actual costs may vary, based on these assumptions your costs, assuming you held your Units for the periods shown, would be: 1 Year 2 Years ______ _______ $ 587 $ 748 The example will not differ if you hold rather than sell your Units at the end of each period. _____________ (a) The combination of the initial and deferred sales charge comprises what we refer to as the "transactional sales charge." The initial sales charge is actually equal to the difference between the maximum sales charge of 3.95% and the sum of any remaining deferred sales charge and creation and development fee. (b) The deferred sales charge is a fixed dollar amount equal to $.245 per Unit which, as a percentage of the Public Offering Price, will vary over time. The deferred sales charge will be deducted in three monthly installments commencing July 18, 2008. (c) The creation and development fee compensates the Sponsor for creating and developing the Trust. The creation and development fee is a charge of $.050 per Unit collected at the end of the initial offering period which is expected to be approximately three months from the Initial Date of Deposit. If the price you pay for your Units exceeds $10 per Unit, the creation and development fee will be less than 0.50%; if the price you pay for your Units is less than $10 per Unit, the creation and development fee will exceed 0.50%. (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. Estimated organization costs are assessed on a fixed dollar amount per Unit basis which, as a percentage of average net assets, will vary over time. (e) With the exception of the underlying Closed-End Fund expenses, 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 for the Trust. In certain circumstances the Trust may incur additional expenses not set forth above. See "Expenses and Charges." (g) Although not an actual Trust operating expense, the Trust, and therefore Unit holders, will indirectly bear similar operating expenses of the Closed-End Funds in which the Trust invests in the estimated amounts set forth in the table. These expenses are estimated based on the actual Closed-End Fund expenses disclosed in a fund's most recent Securities and Exchange Commission filing but are subject to change in the future. An investor in the Trust will therefore indirectly pay higher expenses than if the underlying Closed-End Fund shares were held directly.
Page 4 Report of Independent Registered Public Accounting Firm The Sponsor, First Trust Portfolios L.P., and Unit Holders FT 1664 We have audited the accompanying statement of net assets, including the schedule of investments, of FT 1664, comprising Pioneer Apr. '08 (the "Trust"), as of the opening of business on April 9, 2008 (Initial Date of Deposit). This statement of net assets is the responsibility of the Trust's Sponsor. Our responsibility is to express an opinion on this statement of net assets based on our audit. We conducted our audit in accordance with standards of the Public Company Accounting Oversight Board (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. The Trust is not required to have, nor were we engaged to perform, an audit of the Trust's internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement of net assets, assessing the accounting principles used and significant estimates made by the Trust's Sponsor, as well as evaluating the overall presentation of the statement of net assets. Our procedures included confirmation of the irrevocable letter of credit held by The Bank of New York, the Trustee, and deposited in the Trust for the purchase of Securities, as shown in the statement of net assets, as of the opening of business on April 9, 2008, by correspondence with the Trustee. We believe that our audit 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 1664, comprising Pioneer Apr. '08, at the opening of business on April 9, 2008 (Initial Date of Deposit) in conformity with accounting principles generally accepted in the United States of America.

Actual results could differ from those estimates. (1) The Trust invests in a diversified portfolio of Common Stocks, Closed-End Funds and CITs. Aggregate cost of the Securities listed under "Schedule of Investments" is based on their aggregate underlying value. The Trust has a Mandatory Termination Date of April 9, 2010. (2) An irrevocable letter of credit issued by The Bank of New York, of which approximately $200,000 will be allocated to the Trust, has been deposited with the Trustee as collateral, covering the monies necessary for the purchase of the Securities according to their purchase contracts. (3) A portion of the Public Offering Price consists of an amount sufficient to reimburse the Sponsor for all or a portion of the costs of establishing the Trust. These costs have been estimated at $.0290 per Unit for the Trust. A payment will be made at the earlier of six months after the Initial Date of Deposit or the end of the initial offering period to an account maintained by the Trustee from which the obligation of the investors to the Sponsor will be satisfied. To the extent that actual organization costs 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 of $.245 per Unit, payable to the Sponsor in three approximately equal monthly installments beginning on July 18, 2008 and on the twentieth day of each month thereafter (or if such date is not a business day, on the preceding business day) through September 19, 2008. If Unit holders redeem Units before September 19, 2008, they will have to pay the remaining amount of the deferred sales charge applicable to such Units when they redeem them. (5) The creation and development fee ($.050 per Unit) is payable by the Trust on behalf of Unit holders out of assets of the Trust at the end of the initial offering period. If Units are redeemed prior to the close of the initial offering period, the fee will not be deducted from the proceeds. (6) Net asset value per Unit is calculated by dividing the Trust's net assets by the number of Units outstanding. This figure includes organization costs and the creation and development fee, which will only be assessed to Units outstanding at the earlier of six months after the Initial Date of Deposit or the end of the initial offering period in the case of organization costs or the close of the initial offering period in the case of the creation and development fee. (7) The aggregate cost to investors in the Trust includes a maximum sales charge (comprised of an initial sales charge, a deferred sales charge and the creation and development fee) computed at the rate of 3.95% of the Public Offering Price per Unit (equivalent to 3.99% of the net amount invested, exclusive of the deferred sales charge and the creation and development fee), assuming no reduction of the maximum sales charge as set forth under "Public Offering."

The cost of the Securities to the Sponsor and the Sponsor's loss (which is the difference between the cost of the Securities to the Sponsor and the cost of the Securities to the Trust) are $148,798 and $621, respectively. (3) Common stocks of companies headquartered or incorporated outside the United States comprise approximately 8.34% of the investments of the Trust.

Page 8 The FT Series The FT Series Defined. We, First Trust Portfolios L.P. (the "Sponsor"), have created hundreds of similar yet separate series of a unit investment trust which we have named the FT Series. The series to which this prospectus relates, FT 1664, consists of a single portfolio known as Pioneer Apr. '08. The Trust was created under the laws of the State of New York by a Trust Agreement (the "Indenture") dated the Initial Date of Deposit. This agreement, entered into among First Trust Portfolios L.P., as Sponsor, The Bank of New York as Trustee, FTP Services LLC ("FTPS") as FTPS Unit Servicing Agent 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 SPONSOR AT 1-800-621-1675, EXT. 1. How We Created the Trust. On the Initial Date of Deposit, we deposited a portfolio of Common Stocks, Closed-End Funds and CITs 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 or the equivalent) 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 under "Schedule of Investments"), adjusted to reflect the sale, redemption or liquidation of any of the Securities or any stock split or merger or other similar event affecting the issuer 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 its 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 (the "1940 Act"). 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 Distribution Date. Any Replacement Security the Trust acquires will be identical to those from the failed contract. Portfolio Objectives. The objectives of the Trust are to provide the potential for a high rate of current monthly income and the potential for growth of principal. We believe Pioneer Apr. '08 also offers investors the following: o Diversified exposure to stocks and bonds. o Reduced volatility compared to an all-stock portfolio. When it comes to investing for income, investors have several choices. Even with all the options, there are those investors who do not want to give up growth potential just to earn a high rate of current income. The Pioneer Portfolio has been designed to address this need. To accomplish this, the portfolio invests approximately 25% in common Page 9 stocks and Canadian Income and/or Royalty Trusts and approximately 75% in closed-end funds which invest in U.S. and foreign taxable bonds, senior loans and common stocks. Because stocks and bonds may react differently to changes in the economy and interest rates, diversifying assets in this manner has the potential to reduce the overall volatility of the portfolio while still retaining long-term capital appreciation potential. The Importance of Dividends. Corporations are not obligated to share their earnings with stockholders, so dividends may be viewed as a sign of a company's profitability as well as management's assessment of the future. Dividends have also had a significant impact on stock performance. Consider the historical effect dividends have had on companies in the S&P 500 Index. According to Ibbotson Associates, dividends have provided approximately 43% of the 10.36% average annual total return on the S&P 500 Index, from January 1926 through December 2007. The S&P 500 Index is an unmanaged index of 500 stocks used to measure large-cap U.S. stock market performance. The index cannot be purchased directly by investors. You should be aware that there is no guarantee that the issuers of the securities included in the portfolio will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time. Closed-End Advantages. Portfolio Control. Since closed-end funds maintain a relatively fixed pool of investment capital, portfolio managers are better able to adhere to their investment philosophies through greater flexibility and control. In addition, closed-end funds don't have to manage fund liquidity to meet potentially large redemptions. Diversification. The portfolio offers investors diversification by investing in a broad range of closed-end funds that are further diversified across hundreds of individual issues. Income Distributions. Closed-end funds are structured to generally provide a more stable income stream than other managed fixed-income investment products because they are not subjected to cash inflows and outflows, which can dilute dividends over time. However, as a result of bond calls, redemptions and advanced refundings, which can dilute a fund's income, consistent income cannot be guaranteed. You should be aware that predictions stated herein may not be realized. Of course, as with any similar investments, there can be no guarantee that the objectives of the Trust will be achieved. See "Risk Factors" for a discussion of the risks of investing in the Trust. Risk Factors Price Volatility. The Trust invests in Common Stocks, CITs and Closed- End Funds. The value of the Trust's Units will fluctuate with changes in the value of these Securities. Because the Trust is not managed, the Trustee will not sell Securities in response to or in anticipation of market fluctuations, as is common in managed investments. As with any investment, we cannot guarantee that the performance of the Trust will be positive over any period of time or that you won't lose money. Units of the Trust are not deposits of any bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Distributions. As stated under "Summary of Essential Information," the Trust will generally make monthly distributions of income. The Closed- End Funds held by the Trust make distributions on a monthly or quarterly basis. As a result of changing interest rates, refundings, sales or defaults on the underlying securities held by the Closed-End Funds, and other factors, there is no guarantee that distributions will either remain at current levels or increase over time. There is also no guarantee that the issuers of the Common Stocks or the CITs will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time. Closed-End Funds. A portion of the Trust consists of closed-end funds. Closed-end funds are actively managed investment companies which invest in various types of securities. Closed-end funds issue shares of common stock that are traded on a securities exchange. Closed-end funds are subject to various risks, including management's ability to meet the closed-end fund's investment objective, and to manage the closed-end fund portfolio when the underlying securities are redeemed or sold, during periods of market turmoil and as investors' perceptions regarding closed-end funds or their underlying investments change. Shares of closed-end funds frequently trade at a discount from their net asset value in the secondary market. This risk is separate and distinct from the risk that the net asset value of closed-end fund shares may decrease. The amount of such discount from net asset value is subject to change from time to time in response to various factors. Certain of the Closed-End Funds included in the Trust may employ the use of leverage in their portfolios through borrowings or the issuance of preferred stock. While leverage often serves to increase the yield of a Page 10 closed-end fund, this leverage also subjects the closed-end fund to increased risks, including the likelihood of increased volatility and the possibility that the closed-end fund's common share income will fall if the dividend rate on the preferred shares or the interest rate on any borrowings rises. High-Yield Securities. Certain of the Closed-End Funds in the Trust invest in securities rated below investment grade by one or more rating agencies (high-yield securities or "junk" bonds). High-yield, high risk securities are subject to greater market fluctuations and risk of loss than securities with higher investment ratings. The value of these securities will decline significantly with increases in interest rates, not only because increases in rates generally decrease values, but also because increased rates may indicate an economic slowdown. An economic slowdown, or a reduction in an issuer's creditworthiness, may result in the issuer being unable to maintain earnings at a level sufficient to maintain interest and principal payments. High-yield securities or "junk" bonds, the generic names for securities rated below "BBB-" by Standard & Poor's or below "Baa3" by Moody's, are frequently issued by corporations in the growth stage of their development or by established companies who are highly leveraged or whose operations or industries are depressed. Obligations rated below "BBB-" should be considered speculative as these ratings indicate a quality of less than investment grade. Because high-yield securities are generally subordinated obligations and are perceived by investors to be riskier than higher rated securities, their prices tend to fluctuate more than higher rated bonds and are affected by short-term credit developments to a greater degree. The market for high-yield securities is smaller and less liquid than that for investment grade securities. High-yield securities are generally not listed on a national securities exchange but trade in the over-the-counter markets. Due to the smaller, less liquid market for high-yield securities, the bid-offer spread on such securities is generally greater than it is for investment grade securities and the purchase or sale of such securities may take longer to complete. Common Stocks. A percentage of the Trust consists of common stocks. Common stocks represent a proportional share of ownership in a company. Common stock prices fluctuate for several reasons including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as the market volatility recently exhibited, or when political or economic events affecting the issuers occur. Common stock prices may also be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Options. Certain of the Closed-End Funds in the Trust invest in call options. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value and dividend rates of the stock subject to the option, an increase in interest rates, a change in the actual and perceived volatility of the stock market and the common stock and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the underlying stock (although they generally move in the same direction). However, as an option approaches its expiration date, its value increasingly moves with the price of the stock subject to an option. The strike price for an option may be adjusted downward before an option expiration triggered by certain corporate events affecting that stock. A downward adjustment to the strike price will have the effect of reducing the equity appreciation. Option strike prices may be adjusted to reflect certain corporate events such as extraordinary dividends, stock splits, merger or other extraordinary distributions or events. If the value of the underlying stock exceeds the strike price of an option, it is likely that the holder of that option will exercise their right to purchase the stock. Income/Royalty Trusts. Income/royalty trusts in which the Trust invests are generally equity investments and thus share many of the risks inherent in investing in equity securities, and are also subject to the risks specific to the energy sector. In many circumstances, the income/royalty trusts in which the Trust invests have limited operating histories. The value of income/royalty trusts in which the Trust invests may be influenced by factors that are not within the Trust's control, including the financial performance of the respective issuers, interest rates, exchange rates, commodity prices (which will vary and are determined by supply and demand factors, including weather and general economic and political conditions), the hedging policies employed by such issuers. Income/royalty trusts operating in the energy industry may also be influenced by issues relating to the regulation of the energy industry and operational risks relating to the energy industry. Income/royalty trusts are also subject to the following risks: - Lack of diversification. The income/royalty trusts in which the Trust invests tend to be heavily invested in real estate, oil and gas, pipelines and other infrastructure. - Potential sacrifice of growth. Potential growth may be sacrificed because revenue is passed on to unit holders, rather than reinvested in the business. Page 11 - No guarantees. Income/royalty trusts generally do not guarantee minimum distributions or even return of capital. If the assets underlying an income/royalty trust do not perform as expected, the income/royalty trust may reduce or even eliminate distributions. The declaration of such distributions generally depends upon various factors, including the operating performance and financial condition of the income trust and general economic conditions. - Potential for tax recharacterization or changes. The current Canadian tax treatment of certain income/royalty trusts not treated as corporations that allows income to flow through to investors and be taxed only at the individual level could be challenged under existing Canadian tax laws, or such tax laws could change. Conversely, there may be a risk of recharacterization to such flow-through treatment for U.S. tax purposes. On June 22, 2007, the Canadian Senate passed into law the Tax Fairness Plan, which included a tax on distributions paid by income/royalty trusts. For those income/royalty trusts that begin public trading after October 31, 2006, the application of the distribution tax commenced in 2007. For income/royalty trusts that began public trading before November 1, 2006, which includes all of the income/royalty trusts in the Trust's portolio, the distribution tax will apply beginning in 2011. The distribution tax could have a material impact on the current market value of all income/royalty trusts, and consequently, could impact the value of Units of the Trust. Senior Loans. Certain of the Closed-End Funds in the Trust invest in senior loans issued by banks, other financial institutions and other investors to corporations, partnerships, limited liability companies and other entities to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, debt refinancings and, to a lesser extent, for general operating and other purposes. An investment by closed-end funds in senior loans involves risk that the borrowers under senior loans may default on their obligations to pay principal or interest when due. Although senior loans may be secured by specific collateral, there can be no assurance that liquidation of collateral would satisfy the borrower's obligation in the event of non-payment or that such collateral could be readily liquidated. Senior loans are typically structured as floating rate instruments in which the interest rate payable on the obligation fluctuates with interest rate changes. As a result, the yield on closed-end funds investing in senior loans will generally decline in a falling interest rate environment and increase in a rising interest rate environment. Senior loans are generally below investment grade quality and may be unrated at the time of investment; are generally not registered with the Securities and Exchange Commission or state securities commissions; and are generally not listed on any securities exchange. See "High-Yield Securities" above for a description of the risks involved in investing in below investment grade securities. In addition, the amount of public information available on senior loans is generally less extensive than that available for other types of assets. 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 or Closed-End Funds represented in the Trust or certain of the securities held by the Closed-End Funds. In addition, litigation regarding any of the issuers of the Securities, such as that concerning Reynolds American Inc., or certain of the securities held by the Closed-End Funds, or the industries represented by these issuers, may negatively impact the value of these securities. We cannot predict what impact any pending or proposed legislation or pending or threatened litigation will have on the value of the Securities or the securities held by the Closed-End Funds. Foreign Securities. The CITs and certain of the Common Stocks are, and certain of the Closed-End Funds invest in, securities issued by foreign companies, which makes the Trust subject to more risks than if it invested solely in domestic securities. These Securities are either directly listed on a U.S. securities exchange or are in the form of American Depositary Receipts ("ADRs") which are listed on a U.S. securities exchange. Risks of foreign securities 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; lack of liquidity of certain foreign markets; and less government supervision and regulation of exchanges, brokers and issuers in foreign countries. Emerging Markets. Certain of the Closed-End Funds in the Trust may contain securities issued by companies headquartered in countries considered to be emerging markets. Risks of investing in developing or emerging countries are even greater than the risks associated with foreign investments in general. These increased risks include, among other risks, the possibility of investment and trading limitations, greater liquidity concerns, higher price volatility, greater delays and disruptions in settlement transactions, greater political uncertainties and greater dependence on international trade or development assistance. In addition, emerging market countries may be subject to overburdened infrastructures, obsolete financial systems and environmental problems. For these reasons, investments in emerging markets are often considered speculative.

We have obtained the foregoing descriptions from third-party sources we deem reliable. Page 13 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 sales charge (which combines a deferred sales charge and the creation and development fee). The price you pay for your Units will differ from the amount stated under "Summary of Essential Information" due to various factors, including fluctuations in the prices of the Securities and changes in the value of the Income and/or Capital Accounts. Although you are not required to pay for your Units until three business days following your order (the "date of settlement"), you may pay before then. You will become the owner of Units ("Record Owner") on the date of settlement if payment has been received. If you pay for your Units before the date of settlement, we may use your payment during this time and it may be considered a benefit to us, subject to the limitations of the Securities Exchange Act of 1934. Organization Costs. 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's statement of net assets, 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 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 of the Trust 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 in "Notes to Statement of Net Assets," this will result in a greater effective cost per Unit to Unit holders for the reimbursement to the Sponsor. To the extent actual organization costs are less than the estimated amount, only the actual organization costs will ultimately be charged to the Trust. When Securities are sold to reimburse the Sponsor for organization costs, the Trustee will sell 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 generally $1,000 worth of Units ($500 if you are purchasing Units for your Individual Retirement Account or any other qualified retirement plan), but such amounts may vary depending on your selling firm. Maximum Sales Charge. The maximum sales charge is comprised of a transactional sales charge and a creation and development fee. After the initial offering period the maximum sales charge will be reduced by 0.50%, to reflect the amount of the previously charged creation and development fee. Transactional Sales Charge. The transactional sales charge you will pay has both an initial and deferred component. Initial Sales Charge. The initial sales charge, which you will pay at the time of purchase, is equal to the difference between the maximum sales charge of 3.95% of the Public Offering Price and the sum of the maximum remaining deferred sales charge and creation and development fee (initially $.295 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 and creation and development fee payments are made. When the Public Offering Price exceeds $10.00 per Unit, the initial sales charge will exceed 1.00% of the Public Offering Price. Monthly Deferred Sales Charge. In addition, three monthly deferred sales charges of approximately $.0817 per Unit will be deducted from the Trust's assets on approximately the twentieth day of each month from July 18, 2008 through September 19, 2008. 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 2.45% of the Public Offering Price. Page 14 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 3.45% of the Public Offering Price (equivalent to 3.573% of the net amount invested). The transactional sales charge will be reduced by 1/2 of 1% on each subsequent April 30, commencing April 30, 2009 to a minimum transactional sales charge of 3.00%. Creation and Development Fee. 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 creation and development fee is a charge of $.050 per Unit collected at the end of the initial offering period. If you buy Units at a price of less than $10.00 per Unit, the dollar amount of the creation and development fee will not change, but the creation and development fee on a percentage basis will be more than 0.50% of the Public Offering Price. Discounts for Certain Persons. If you invest at least $50,000 (except if you are purchasing for "Fee Accounts" as described below), the maximum sales charge is reduced as follows: Your maximum Dealer If you invest sales charge concession (in thousands):* will be: will be: _______________ __________ __________ $50 but less than $100 3.70% 2.90% $100 but less than $250 3.45% 2.65% $250 but less than $500 3.10% 2.35% $500 but less than $1,000 2.95% 2.25% $1,000 or more 2.45% 1.80% * The breakpoints will be adjusted to take into consideration purchase orders stated in dollars which cannot be completely fulfilled due to the requirement that only whole Units be issued. The reduced sales charge for quantity purchases will apply only to purchases made by the same person on any one day from any one dealer. To help you reach the above levels, you can combine the Units you purchase of the Trust with any other same day purchases of other trusts for which we are Principal Underwriter and are currently in the initial offering period. In addition, we will also consider Units you purchase in the name of your spouse or child under 21 years of age to be purchases by you. The reduced sales charges will also apply to a trustee or other fiduciary purchasing Units for a single trust estate or single fiduciary account. You must inform your dealer of any combined purchases before the sale in order to be eligible for the reduced sales charge. You may use termination proceeds from other unit investment trusts with a similar strategy as the Trust or your redemption or termination proceeds from any unit investment trust we sponsor to purchase Units of the Trust during the initial offering period at the Public Offering Price less 1.00% (for purchases of $1,000,000 or more, the maximum sales charge will be limited to 2.45% of the Pubic Offering Price), but you will not be eligible to receive the reduced sales charges described in the above table. Please note that if you purchase Units of the Trust in this manner using redemption proceeds from trusts which assess the amount of any remaining deferred sales charge at redemption, you should be aware that any deferred sales charge remaining on these units will be deducted from those redemption proceeds. In order to be eligible for this reduced sales charge program, the termination or redemption proceeds used to purchase Units must be derived from a transaction that occurred within 30 days of your Unit purchase. In addition, this program will only be available for investors that utilize the same broker/dealer (or a different broker/dealer with appropriate notification) for both the Unit purchase and the transaction resulting in the receipt of the termination or redemption proceeds used for the Unit purchase. You may be required to provide appropriate documentation or other information to your broker/dealer to evidence your eligibility for this reduced sales charge program. Investors purchasing Units through registered broker/dealers who charge periodic fees in lieu of commissions or who charge for financial planning, investment advisory or asset management services, or provide these or comparable services as part of an investment account where a comprehensive "wrap fee" or similar charge is imposed ("Fee Accounts") will not be assessed the deferred sales charge described in this section on the purchase of Units in the primary market. Certain Fee Accounts Unit holders may be assessed transaction or other account fees on the purchase and/or redemption of such Units by their broker/dealer or other processing organizations for providing certain transaction or account activities. Fee Accounts Units are not available for purchase in the secondary market. We reserve the right to limit or deny purchases of Units not subject to the transactional sales charge by investors whose frequent trading activity we determine to be detrimental to the Trust. Employees, officers and directors (and immediate family members) of the Sponsor, our related companies and dealers may purchase Units at the Public Offering Price less the applicable dealer concession. Immediate family members include spouses, children, grandchildren, parents, grandparents, siblings, mothers-in-law, fathers-in-law, sons-in-law, daughters-in-law, brothers-in-law and sisters-in-law, and trustees, custodians or fiduciaries for the benefit of such persons. Page 15 The Sponsor and certain dealers may establish a schedule where employees, officers and directors of such dealers can purchase Units of the Trust at the Public Offering Price less the established schedule amount, which is designed to compensate such dealers for activities relating to the sale of Units (the "Employee Dealer Concession"). You will be charged the deferred sales charge per Unit regardless of any discounts. However, if you are eligible to receive a discount such that the maximum sales charge you must pay is less than the applicable maximum deferred sales charge, including Fee Accounts Units, you will be credited the difference between your maximum sales charge and the maximum deferred sales charge at the time you buy your Units. If you elect to have distributions reinvested into additional Units of the Trust, in addition to the reinvestment Units you receive you will also be credited additional Units with a dollar value at the time of reinvestment sufficient to cover the amount of any remaining deferred sales charge and creation and development fee 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 or the creation and development fee are collected than their value at the time they were issued. 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 in the Trust will be determined as follows: if the Securities are listed on a securities exchange or The NASDAQ Stock Market(R), 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, as may be the case with certain foreign Securities listed on a foreign securities exchange). For purposes of valuing Securities traded on The NASDAQ Stock Market(R), closing sale price shall mean the NASDAQ(R) Official Closing Price ("NOCP") as determined by The Nasdaq Stock Market, Inc. 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 or, if available but determined by the Evaluator to not be appropriate, 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. The Sponsor compensates intermediaries, such as broker/dealers and banks, for their activities that are intended to result in sales of Units of the Trust. This compensation includes dealer concessions described in the following section and may include additional concessions and other compensation and benefits to broker/dealers and other intermediaries. Dealer Concessions. Dealers and other selling agents can purchase Units at prices which represent a concession or agency commission of 3.15% of the Public Offering Price per Unit (or 65% of the maximum transactional sales charge for secondary market sales), subject to the reduced concession applicable to volume purchases as set forth in "Public Offering- Discounts for Certain Persons." However, for Units subject to a transactional sales charge which are purchased using redemption or termination proceeds, this amount will be reduced to 2.15% of the sales price of these Units (1.80% for purchases of $1,000,000 or more). Eligible dealer firms and other selling agents who, during the previous consecutive 12-month period through the end of the most recent month, sold primary market units of unit investment trusts sponsored by us in the dollar amounts shown below will be entitled to the following Page 16 additional sales concession on primary market sales of units during the current month of unit investment trusts sponsored by us: Total sales Additional (in millions) Concession ______________________ __________ $25 but less than $100 0.050% $100 but less than $150 0.075% $150 but less than $250 0.100% $250 but less than $500 0.115% $500 but less than $750 0.125% $750 but less than $1,000 0.130% $1,000 but less than $1,500 0.135% $1,500 but less than $2,000 0.140% $2,000 but less than $3,000 0.150% $3,000 but less than $4,000 0.160% $4,000 but less than $5,000 0.170% $5,000 or more 0.175% Dealers and other selling agents will not receive a concession on the sale of Units which are not subject to a transactional sales charge, but such Units will be included in determining whether the above volume sales levels are met. Eligible dealer firms and other selling agents include clearing firms that place orders with First Trust and provide First Trust with information with respect to the representatives who initiated such transactions. Eligible dealer firms and other selling agents will not include firms that solely provide clearing services to other broker/dealer firms or firms who place orders through clearing firms that are eligible dealers. 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. Other Compensation and Benefits to Broker/Dealers. The Sponsor, at its own expense and out of its own profits, currently provides additional compensation and benefits to broker/dealers who sell shares of Units of this Trust and other First Trust products. This compensation is intended to result in additional sales of First Trust products and/or compensate broker/dealers and financial advisors for past sales. A number of factors are considered in determining whether to pay these additional amounts. Such factors may include, but are not limited to, the level or type of services provided by the intermediary, the level or expected level of sales of First Trust products by the intermediary or its agents, the placing of First Trust products on a preferred or recommended product list, access to an intermediary's personnel, and other factors. The Sponsor makes these payments for marketing, promotional or related expenses, including, but not limited to, expenses of entertaining retail customers and financial advisers, advertising, sponsorship of events or seminars, obtaining information about the breakdown of unit sales among an intermediary's representatives or offices, obtaining shelf space in broker/dealer firms and similar activities designed to promote the sale of the Sponsor's products. The Sponsor makes such payments to a substantial majority of intermediaries that sell First Trust products. The Sponsor may also make certain payments to, or on behalf of, intermediaries to defray a portion of their costs incurred for the purpose of facilitating Unit sales, such as the costs of developing or purchasing trading systems to process Unit trades. Payments of such additional compensation described in this and the preceding paragraph, some of which may be characterized as "revenue sharing," may create an incentive for financial intermediaries and their agents to sell or recommend a First Trust product, including the Trust, over products offered by other sponsors or fund companies. These arrangements will not change the price you pay for your Units. In addition, as compensation for purchasing a portion of the unit investment trust business of Citigroup Global Markets Inc. ("CGMI"), we will pay CGMI a fee based on the dollar amount of proceeds from unit investment trusts formerly sponsored by CGMI which are invested in trusts sponsored by us which equates to $3.50 per $1,000 invested. This payment will be made out of our profits and not from assets of the Trust. Advertising and Investment Comparisons. Advertising materials regarding the Trust may discuss several topics, including: developing a long-term financial plan; working with your financial professional; the nature and risks of various investment strategies and unit investment trusts that could help you reach your financial goals; the importance of discipline; how the Trust operates; how securities are selected; various unit investment trust features such as convenience and costs; and options available for certain types of unit investment trusts. These materials may include descriptions of the principal businesses of the companies represented in the Trust, research analysis of why they were selected and information relating to the qualifications of the persons or entities providing the research analysis. In addition, they may include research opinions on the economy and industry sectors included and a list of investment products generally appropriate for pursuing those recommendations. From time to time we may compare the estimated returns of the Trust (which may show performance net of the expenses and charges the Trust Page 17 would have incurred) and returns over specified periods of other similar trusts we sponsor in our advertising and sales materials, with (1) returns on other taxable investments such as the common stocks comprising various market indexes, corporate or U.S. Government bonds, bank CDs and money market accounts or funds, (2) performance data from Morningstar Publications, Inc. or (3) information from publications such as Money, The New York Times, U.S. News and World Report, BusinessWeek, Forbes or Fortune. The investment characteristics of the Trust differ from other comparative investments. You should not assume that these performance comparisons will be representative of the Trust's future performance. We may also, from time to time, use advertising which classifies trusts or portfolio securities according to capitalization and/or investment style. The Sponsor's Profits We will receive a gross sales commission equal to the maximum deferred sales charge per Unit of the Trust less any reduction as stated in "Public Offering." We will also receive the amount of any collected creation and development fee. Also, any difference between our cost to purchase the Securities and the price at which we sell them to the Trust is considered a profit or loss (see Note 2 of "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 and 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) may sell tendered Units in the over-the- counter market, if any. However, the amount you will receive is the same as you would have received on redemption of the Units. Expenses and Charges The estimated annual expenses of the Trust are listed under "Fee Table." If actual expenses exceed the estimate, the Trust will bear the excess. 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. In addition, investors will also indirectly pay a portion of the expenses of the underlying Closed-End Funds. First Trust Advisors L.P., an affiliate of ours, acts as Portfolio Supervisor and Evaluator and will be compensated for providing portfolio supervisory services and evaluation services as well as bookkeeping and other administrative services to the Trust. In providing portfolio supervisory services, the Portfolio Supervisor may purchase research services from a number of sources, which may include underwriters or dealers of the Trust. As Sponsor, we will receive brokerage fees when the Trust uses us (or an affiliate of ours) as agent in buying or selling Securities. As authorized by the Indenture, the Trustee may employ a subsidiary or affiliate of the Trustee to act as broker to execute certain transactions for the Trust. The Trust will pay for such services at standard commission rates. FTP Services LLC, an affiliate of ours, acts as FTPS Unit Servicing Agent to the Trust with respect to the Trust's FTPS Units. FTPS Units are Units which are purchased and sold through the Fund/SERV(R) trading system or on a manual basis through FTP Services LLC. In all other Page 18 respects, FTPS Units are identical to other Units. FTP Services LLC will be compensated for providing shareholder services to the FTPS Units. The fees payable to First Trust Advisors L.P., FTP Services LLC and the Trustee are based on the largest aggregate number of Units of the Trust outstanding at any time during the calendar year, except during the initial offering period, in which case these fees are calculated based on the largest number of Units outstanding during the period for which compensation is paid. These fees may be adjusted for inflation without Unit holders' approval, but in no case will the annual fees paid to us or our affiliates for providing services to all unit investment trusts be more than the actual cost of providing such services in such year. As Sponsor, we will receive a fee from the Trust for creating and developing the Trust, including determining the Trust's objectives, policies, composition and size, selecting service providers and information services and for providing other similar administrative and ministerial functions. The "creation and development fee" is a charge of $.050 per Unit outstanding at the end of the initial offering period. The Trustee will deduct this amount from the Trust's assets as of the close of the initial offering period. We do not use this fee to pay distribution expenses or as compensation for sales efforts. This fee will not be deducted from your proceeds if you sell or redeem your Units before the end of the initial offering period. In addition to the Trust's operating expenses and those fees described above, each 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; - Foreign custodial and transaction fees, if any; 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, CITs and closed- end funds, 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 in the Trust to make cash available to pay these charges which may result in capital gains or losses to you. See "Tax Status." Tax Status Federal Tax Matters. This section summarizes some of the main U.S. federal income tax consequences of owning Units of the Trust. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker/dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or foreign tax consequences. This federal income tax summary is based in part on the advice and opinion of counsel to the Sponsor. The Internal Revenue Service ("IRS") could disagree with any conclusions set forth in this section. In addition, our counsel was not asked to review, and has not reached a conclusion with respect to the federal income tax treatment of the assets to be deposited in the Trust. This may not be sufficient for you to use for the purpose of avoiding penalties under federal tax law. As with any investment, you should seek advice based on your individual circumstances from your own tax advisor. Assets of the Trust. The Trust is expected to hold one or more of the following (i) stock in domestic and foreign corporations (the "Stocks") that are treated as equity for federal income tax purposes and (ii) shares of Closed-End Funds (the "RIC Shares") qualifying as regulated investment companies ("RICs") that are treated as interests in regulated investment companies for federal income tax purposes. It is possible that the Trust will also hold other assets, including assets that are treated differently for federal income tax purposes from those described above, in which case you will have federal income tax consequences different from or in addition to those described in this section. All of the assets held by the Trust constitute the "Trust Assets." Neither our counsel nor we have analyzed the proper federal income tax treatment of the Trust Assets and thus neither our counsel nor we have reached a conclusion regarding the federal income tax treatment of the Trust Assets. Page 19 Trust Status. If the Trust is at all times operated in accordance with the documents establishing the Trust and certain requirements of federal income tax law are met, 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 each of the Trust Assets, and as such you will be considered to have received a pro rata share of income (e.g., dividends and capital gains, if any) from each Trust Asset when such income would be considered to be received by you if you directly owned the Trust Assets. This is true even if you elect to have your distributions reinvested into additional Units. In addition, the income from Trust Assets that you must take into account for federal income tax purposes is not reduced by amounts used to pay sales charges or Trust expenses. Your Tax Basis and Income or Loss upon Disposition. If the Trust disposes of Trust Assets, you will generally recognize gain or loss. If you dispose of your Units or redeem your Units for cash, you will also generally recognize gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in the related Trust Assets from your share of the total amount received in the transaction. You can generally determine your initial tax basis in each Trust Asset by apportioning the cost of your Units, including sales charges, among the Trust Assets ratably according to their values on the date you acquire your Units. In certain circumstances, however, you may have to adjust your tax basis after you acquire your Units (for example, in the case of certain dividends that exceed a corporation's accumulated earnings and profits, as discussed below). If you are an individual, the maximum marginal federal tax rate for net capital gain is generally 15% (generally 5% for certain taxpayers in the 10% and 15% tax brackets). These capital gains rates are generally effective for taxable years beginning before January 1, 2011. Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your Units to determine your holding period. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code, however, treats certain capital gains as ordinary income in special situations. Dividends from Stocks. Certain dividends received with respect to the Stocks may qualify to be taxed at the same rates that apply to net capital gain (as discussed above), provided certain holding period requirements are satisfied. These special rules relating to the taxation of dividends at capital gains rates generally apply to taxable years beginning before January 1, 2011. Dividends from RIC Shares. Some dividends on the RIC Shares may be designated as "capital gain dividends," generally taxable to you as long-term capital gains. Other dividends on the RIC Shares will generally be taxable to you as ordinary income. Certain ordinary income dividends from a RIC may qualify to be taxed at the same rates that apply to net capital gain (as discussed above), provided certain holding period requirements are satisfied and provided the dividends are attributable to qualifying dividends received by the RIC itself. These special rules relating to the taxation of ordinary income dividends from regulated investment companies generally apply to taxable years beginning before January 1, 2011. RICs are required to provide notice to their shareholders of the amount of any distribution that may be taken into account as a dividend that is eligible for the capital gains tax rates. If you hold a Unit for six months or less or if the Trust holds a RIC Share for six months or less, any loss incurred by you related to the disposition of such RIC Share will be treated as a long-term capital loss to the extent of any long- term capital gain distributions received (or deemed to have been received) with respect to such RIC Share. Distributions of income or capital gains declared on the RIC Shares in October, November or December will be deemed to have been paid to you on December 31 of the year they are declared, even when paid by the RIC during the following January. Dividends Received Deduction. A corporation that owns Units generally will not be entitled to the dividends received deduction with respect to dividends received by the Trust, because the dividends received deduction is generally not available for dividends from most foreign corporations or from RICs. However, certain dividends on the RIC Shares that are attributable to dividends received by the RIC from certain domestic corporations may be designated by the RIC as being eligible for the dividends received deduction. In-Kind Distributions. Under certain circumstances as described in this prospectus, you may request an In-Kind Distribution of Trust Assets when you redeem your Units at any time prior to 30 business days before the Trust's Mandatory Termination Date. However, this ability to request an In-Kind Distribution will terminate at any time that the number of outstanding Page 20 Units has been reduced to 10% or less of the highest number of Units issued by the Trust. By electing to receive an In-Kind Distribution, you will receive Trust Assets plus, possibly, cash. You will not recognize gain or loss if you only receive whole Trust Assets in exchange for the identical amount of your pro rata portion of the same Trust Assets held by the Trust. However, if you also receive cash in exchange for a Trust Asset or a fractional portion of a Trust Asset, you will generally recognize gain or loss based on the difference between the amount of cash you receive and your tax basis in such Trust Asset or fractional portion. 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 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. Distributions by the Trust that are treated as U.S. source income (e.g., dividends received on Stocks of domestic corporations) will generally be subject to U.S. income taxation and withholding in the case of Units held by nonresident alien individuals, foreign corporations or other non- U.S. persons, subject to any applicable treaty. If you are a foreign investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you may not be subject to U.S. federal income taxes, including withholding taxes, on some of the income from the Trust or on any gain from the sale or redemption of your Units, provided that certain conditions are met. You should consult your tax advisor with respect to the conditions you must meet in order to be exempt for U.S. tax purposes. You should also consult your tax advisor with respect to other U.S. tax withholding and reporting requirements. Some distributions by the Trust may be subject to foreign withholding taxes. Any income withheld will still be treated as income to you. Under the grantor trust rules, you are considered to have paid directly your share of any foreign taxes that are paid. Therefore, for U.S. tax purposes, you may be entitled to a foreign tax credit or deduction for those foreign taxes. Under certain circumstances, a RIC may elect to pass through to its shareholders certain foreign taxes paid by the RIC. If the RIC makes this election with respect to RIC Shares, you must include in your income for federal income tax purposes your portion of such taxes and you may be entitled to a credit or deduction for such taxes. If any U.S. investor is treated as owning directly or indirectly 10% or more of the combined voting power of the stock of a foreign corporation, and all U.S. shareholders of that corporation collectively own more than 50% of the vote or value of the stock of that corporation, the foreign corporation may be treated as a controlled foreign corporation (a "CFC"). If you own 10% or more of a CFC (through the Trust and in combination with your other investments) you will be required to include certain types of the CFC's income in your taxable income for federal income tax purposes whether or not such income is distributed to the Trust or to you. Based on the advice of Carter Ledyard & Milburn LLP, special counsel to the Trust for New York tax matters, under the existing income tax laws of the State and City of New York, assuming that the Trust is not treated as a corporation for federal income tax purposes, it will not be taxed as a corporation for New York State and New York City tax purposes, 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. You should consult your tax advisor regarding potential foreign, state or local taxation with respect to your Units. 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. Page 21 Rights of Unit Holders Unit Ownership. The Trustee will treat as Record Owner of Units persons registered as such on its books. For the purposes of record keeping, the Trustee will treat the FTPS Unit Servicing Agent as sole Record Owner of FTPS Units on its books. The FTPS Unit Servicing Agent will keep a record of all individual FTPS Unit holders, the actual Record Owners of such Units, on its books. It is your responsibility to notify the Trustee (or the FTPS Unit Servicing Agent in the case of FTPS Units) when you become Record Owner, but normally your broker/dealer provides this notice. You may elect to hold your Units in either certificated or uncertificated form. All Fee Accounts Units and FTPS Units, however, will be held in uncertificated form. Certificated Units. When you purchase your Units you can request that they be evidenced by certificates, which will be delivered shortly after your order. Certificates will be issued in fully registered form, transferable only on the books of the Trustee in denominations of one Unit or any multiple thereof. You can transfer or redeem your certificated Units by endorsing and surrendering the certificate to the Trustee, along with a written instrument of transfer. You must sign your name exactly as it appears on the face of the certificate with your signature guaranteed by an eligible institution. In certain cases the Trustee may require additional documentation before they will transfer or redeem your Units. You may be required to pay a nominal fee to the Trustee for each certificate reissued or transferred, and to pay any government charge that may be imposed for each transfer or exchange. If a certificate gets lost, stolen or destroyed, you may be required to furnish indemnity to the Trustee to receive replacement certificates. You must surrender mutilated certificates to the Trustee for replacement. Uncertificated Units. You may also choose to hold your Units in uncertificated form. If you choose this option, the Trustee (or the FTPS Unit Servicing Agent in the case of FTPS Units) 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) will send you: - A written initial transaction statement containing a description of the Trust; - A list of the number of Units issued or transferred; - Your name, address and Taxpayer Identification Number ("TIN"); - A notation of any liens or restrictions of the issuer and any adverse claims; and - The date the transfer was registered. 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) will provide you with the following information: - 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) 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 of the Trust. All other receipts, such as return of capital or capital gain dividends, are credited to the Capital Account of the Trust. The Trustee will distribute money from the Income and Capital Accounts, as determined at the monthly Record Date, monthly on the twenty-fifth day of each month to Unit holders on the tenth day of such month provided the aggregate amount, exclusive of sale proceeds, available for distribution in the Income and Capital Accounts equals at least 0.1% of the net asset value of the Trust. Undistributed money in the Income and Capital Accounts will be distributed in the next month in which the aggregate amount available for distribution, exclusive of sale proceeds, Page 22 equals or exceeds 0.1% of the net asset value of the Trust. 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 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 sale proceeds in the Capital Account, net of amounts designated to meet redemptions, pay the deferred sales charge and creation and development fee or pay expenses, on the twenty-fifth day of each month to Unit holders of record on the tenth day of such 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 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 of the Trust 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, you will receive the pro rata share of the money from the sale of the Securities. All Unit holders 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) at least 10 days before any Record Date. Each later distribution of income and/or capital on your Units will be reinvested by the Trustee into additional Units of the Trust. There is no sales charge on Units acquired through the Distribution Reinvestment Option, as discussed under "Public Offering." This option may not be available in all states. Each reinvestment plan is subject to availability or limitation by the Sponsor and each broker/dealer or selling firm. The Sponsor or broker/dealers may suspend or terminate the offering of a reinvestment plan at any time. Please contact your financial professional for additional information. 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 the address set forth on the back cover of this prospectus. If your Units are uncertificated, you need only deliver a request for redemption to the Trustee (or the FTPS Unit Servicing Agent in the case of FTPS Units). 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) 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 (or the FTPS Unit Servicing Agent in the case of FTPS Units) 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 at least 2,500 Units, or such other amount as required by your broker/dealer, for redemption, rather than receiving cash, you may elect to receive an In-Kind Distribution in an amount equal to the Redemption Price per Unit by making this request in writing to the Trustee at the time of tender. However, to be eligible to participate in the In-Kind Distribution option at redemption, Fee Accounts Unit holders Page 23 must hold their Units through the end of the initial offering period. The In-Kind Distribution option is generally not available to FTPS Unit holders. No In-Kind Distribution requests submitted during the 30 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 of the Trust not designated to purchase Securities; 2.the aggregate 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 the initial offering period, the Redemption Price per Unit will include estimated organization costs as set forth under "Fee Table." Removing Securities from the Trust The portfolio of the Trust is not managed. However, we may, but are not required to, direct the Trustee to dispose of 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; - The sale of Securities is necessary or advisable in order to maintain the qualification of the Trust as a "regulated investment company" in the case of a Trust which has elected to qualify as such; - 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; or - As a result of the ownership of the Security, the Trust or its Unit holders would be a direct or indirect shareholder of a passive foreign investment company. Except in the limited instance in which the Trust acquires Replacement Securities, as described in "The FT Series," the Trust may not acquire Page 24 any securities or other property other than the Securities. The Trustee, on behalf of the Trust, will reject any offer for new or exchanged securities or property in exchange for a Security, such as those acquired in a merger or other transaction. If such exchanged securities or property are nevertheless acquired by the Trust, at our instruction they will either be sold or held in the Trust. In making the determination as to whether to sell or hold the exchanged securities or property we may get advice from the Portfolio Supervisor. Any proceeds received from the sale of Securities, exchanged securities or property will be credited to the Capital Account of the Trust 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 1940 Act. 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. 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 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 of the Trust; - 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 the Trust are tendered for redemption by underwriters, including the Sponsor. Prior to termination, the Trustee will send written notice to registered account holders which will specify how certificates, if any, should be tendered to the Trustee. If the Trust is terminated due to this last reason, we will refund your entire 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, 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. You will receive a cash distribution from the sale of the remaining Securities, along with your interest in the Income and Capital Accounts, within a reasonable time after the Trust is terminated. The Trustee will deduct from the Trust any accrued costs, expenses, advances or indemnities provided for by the Indenture, including estimated compensation of the Trustee and costs of liquidation and any amounts required as a reserve to pay any taxes or other governmental charges.

Table of Contents Risk Factors Common Stocks 1 Closed-End Funds 1 Dividends 2 Foreign Issuers 2 Senior Loans 3 High-Yield Securities 3 Emerging Markets 4 Investing 4 Liquidity/Settlement 5 Political 5 Trade 5 Litigation Tobacco Industry 5 Risk Factors Common Stocks. 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 Common Stocks or the general condition of the relevant stock market may worsen, and the value of the Common Stocks 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. Closed-End Funds. Closed-end mutual funds' portfolios are managed and their shares are generally listed on a securities exchange. The net asset value of closed-end fund shares will fluctuate with changes in the value of the underlying securities which the closed-end fund owns. In addition, for various reasons closed-end fund shares frequently trade at a discount from their net asset value in the secondary market. The amount of such discount from net asset value is subject to change from time to time in response to various factors. Closed-end funds' articles of incorporation may contain certain anti-takeover provisions that may have the effect of inhibiting a fund's possible conversion to open-end status and limiting the ability of other persons to acquire control of a fund. In certain circumstances, these provisions might also inhibit the ability of stockholders (including the Trust) to sell their shares at a premium over prevailing market prices. This characteristic is a risk separate and distinct from the risk that a fund's net asset value will decrease. In particular, this characteristic would increase the loss or reduce the return on the sale of those closed-end fund shares which were purchased by a Trust at a premium. In the unlikely event that a closed- end fund converts to open-end status at a time when its shares are trading at a premium there would be an immediate loss in value to the Trust since shares of open-end funds trade at net asset value. Certain closed-end funds may have in place or may put in place in the future plans pursuant to which the fund may repurchase its own shares in the Page 1 marketplace. Typically, these plans are put in place in an attempt by a fund's board of directors to reduce a discount on its share price. To the extent such a plan was implemented and shares owned by a Trust are repurchased by a fund, the Trust's position in that fund would be reduced and the cash would be distributed. The Trust is prohibited from subscribing to a rights offering for shares of any of the closed-end funds in which they invest. In the event of a rights offering for additional shares of a fund, Unit holders should expect that their Trust will, at the completion of the offer, own a smaller proportional interest in such fund that would otherwise be the case. It is not possible to determine the extent of this dilution in share ownership without knowing what proportion of the shares in a rights offering will be subscribed. This may be particularly serious when the subscription price per share for the offer is less than the fund's net asset value per share. Assuming that all rights are exercised and there is no change in the net asset value per share, the aggregate net asset value of each shareholder's shares of common stock should decrease as a result of the offer. If a fund's subscription price per share is below that fund's net asset value per share at the expiration of the offer, shareholders would experience an immediate dilution of the aggregate net asset value of their shares of common stock as a result of the offer, which could be substantial. Closed-end funds may utilize leveraging in their portfolios. Leveraging can be expected to cause increased price volatility for those fund's shares, and as a result, increased volatility for the price of the Units of a Trust. There can be no assurance that a leveraging strategy will be successful during any period in which it is employed. 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 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. Page 2 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. Senior Loans. Certain of the Closed-End Funds in the Trust invest in senior loans issued by banks, other financial institutions, and other investors to corporations, partnerships, limited liability companies and other entities to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, debt refinancings and, to a lesser extent, for general operating and other purposes. An investment by Closed-End Funds in senior loans involves risk that the borrowers under senior loans may default on their obligations to pay principal or interest when due. Although senior loans may be secured by specific collateral, there can be no assurance that liquidation of collateral would satisfy the borrower's obligation in the event of non-payment or that such collateral could be readily liquidated. Senior loans are typically structured as floating rate instruments in which the interest rate payable on the obligation fluctuates with interest rate changes. As a result, the yield on Closed-End Funds investing in senior loans will generally decline in a falling interest rate environment and increase in a rising interest rate environment. Senior loans are generally below investment grade quality and may be unrated at the time of investment; are generally not registered with the SEC or state securities commissions; and are generally not listed on any securities exchange. In addition, the amount of public information available on senior loans is generally less extensive than that available for other types of assets. High-Yield Securities. An investment in Units of the Trust should be made with an understanding of the risks that an investment in high- yield, high-risk, fixed-rate, domestic and foreign securities or "junk" bonds may entail, including increased credit risks and the risk that the value of the Units will decline, and may decline precipitously, with increases in interest rates. In recent years there have been wide fluctuations in interest rates and thus in the value of fixed-rate securities generally. Securities such as those included in the Closed- End Funds in the Trust are, under most circumstances, subject to greater market fluctuations and risk of loss of income and principal than are investments in lower-yielding, higher-rated securities, and their value may decline precipitously because of increases in interest rates, not only because the increases in rates generally decrease values, but also because increased rates may indicate a slowdown in the economy and a decrease in the value of assets generally that may adversely affect the credit of issuers of high-yield, high-risk securities resulting in a higher incidence of defaults among high-yield, high-risk securities. A slowdown in the economy, or a development adversely affecting an issuer's creditworthiness, may result in the issuer being unable to maintain earnings or sell assets at the rate and at the prices, respectively, that are required to produce sufficient cash flow to meet its interest and principal requirements. For an issuer that has outstanding both senior commercial bank debt and subordinated high- yield, high-risk securities, an increase in interest rates will increase that issuer's interest expense insofar as the interest rate on the bank debt is fluctuating. However, many leveraged issuers enter into interest rate protection agreements to fix or cap the interest rate on a large portion of their bank debt. This reduces exposure to increasing rates, but reduces the benefit to the issuer of declining rates. The Sponsor cannot predict future economic policies or their consequences or, therefore, the course or extent of any similar market fluctuations in the future. High-yield securities or "junk" bonds, the generic names for securities rated below "BBB-" by Standard & Poor's, or below "Baa3" by Moody's, are frequently issued by corporations in the growth stage of their development, by established companies whose operations or industries are depressed or by highly leveraged companies purchased in leveraged buyout transactions. The market for high-yield securities is very specialized and investors in it have been predominantly financial institutions. High- yield securities are generally not listed on a national securities exchange. Trading of high-yield securities, therefore, takes place primarily in over-the-counter markets which consist of groups of dealer firms that are typically major securities firms. Because the high-yield security market is a dealer market, rather than an auction market, no single obtainable price for a given security prevails at any given time. Prices are determined by negotiation between traders. The existence of a liquid trading market for the securities may depend on whether dealers will make a market in the securities. There can be no assurance that a market will be made for any of the securities, that any market for the securities will be maintained or of the liquidity of the securities in Page 3 any markets made. Not all dealers maintain markets in all high-yield securities. Therefore, since there are fewer traders in these securities than there are in "investment grade" securities, the bid-offer spread is usually greater for high-yield securities than it is for investment grade securities. Lower-rated securities tend to offer higher yields than higher-rated securities with the same maturities because the creditworthiness of the issuers of lower-rated securities may not be as strong as that of other issuers. Moreover, if a fixed-income security is recharacterized as equity by the Internal Revenue Service for federal income tax purposes, the issuer's interest deduction with respect to the security will be disallowed and this disallowance may adversely affect the issuer's credit rating. Because investors generally perceive that there are greater risks associated with the lower-rated securities in the Closed- End Funds in the Trust, the yields and prices of these securities tend to fluctuate more than higher-rated securities with changes in the perceived quality of the credit of their issuers. In addition, the market value of high-yield, high-risk, fixed-income securities may fluctuate more than the market value of higher-rated securities since high-yield, high-risk, fixed-income securities tend to reflect short- term credit development to a greater extent than higher-rated securities. Lower-rated securities generally involve greater risks of loss of income and principal than higher-rated securities. Issuers of lower-rated securities may possess fewer creditworthiness characteristics than issuers of higher-rated securities and, especially in the case of issuers whose obligations or credit standing have recently been downgraded, may be subject to claims by debtholders, owners of property leased to the issuer or others which, if sustained, would make it more difficult for the issuers to meet their payment obligations. High-yield, high-risk securities are also affected by variables such as interest rates, inflation rates and real growth in the economy. Therefore, investors should consider carefully the relative risks associated with investment in securities which carry lower ratings. The value of the Units reflects the value of the Closed-End Funds in the Trust which in turn reflect the value of their portfolio securities, including the value (if any) of securities in default. Should the issuer of any security default in the payment of principal or interest, the Closed-End Funds in the Trust may incur additional expenses seeking payment on the defaulted security. Because amounts (if any) recovered by the Closed-End Funds in the Trust in payment under the defaulted security may not be reflected in the value of the Closed-End Fund shares until actually received by the Closed-End Funds, and depending upon when a Unit holder purchases or sells his or her Units, it is possible that a Unit holder would bear a portion of the cost of recovery without receiving any portion of the payment recovered. High-yield, high-risk securities are generally subordinated obligations. The payment of principal (and premium, if any), interest and sinking fund requirements with respect to subordinated obligations of an issuer is subordinated in right of payment to the payment of senior obligations of the issuer. Senior obligations generally include most, if not all, significant debt obligations of an issuer, whether existing at the time of issuance of subordinated debt or created thereafter. Upon any distribution of the assets of an issuer with subordinated obligations upon dissolution, total or partial liquidation or reorganization of or similar proceeding relating to the issuer, the holders of senior indebtedness will be entitled to receive payment in full before holders of subordinated indebtedness will be entitled to receive any payment. Moreover, generally no payment with respect to subordinated indebtedness may be made while there exists a default with respect to any senior indebtedness. Thus, in the event of insolvency, holders of senior indebtedness of an issuer generally will recover more, ratably, than holders of subordinated indebtedness of that issuer. Obligations that are rated lower than "BBB-" by Standard & Poor's, or "Baa3" by Moody's, respectively, should be considered speculative as such ratings indicate a quality of less than investment grade. Investors should carefully review the objective of the Trust and consider their ability to assume the risks involved before making an investment in the Trust. Emerging Markets. An investment in Units of the Trust should be made with an understanding of the risks inherent with investing in certain smaller and emerging markets. Investing. Compared to more mature markets, some emerging markets may have a low level of regulation, enforcement of regulations and monitoring of investors' activities. Those activities may include practices such as trading on material non-public information. The securities markets of developing countries are not as large as the more established securities markets and have substantially less trading volume, resulting in a lack of liquidity and high price volatility. There may be a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries as well as a high concentration of investors and financial intermediaries. These factors may adversely affect the timing and pricing of the acquisition or disposal of securities. Page 4 In certain emerging markets, registrars are not subject to effective government supervision nor are they always independent from issuers. The possibility of fraud, negligence, undue influence being exerted by the issuer or refusal to recognize ownership exists, which, along with other factors, could result in the registration of a shareholding being completely lost. Investors should therefore be aware that the Trust could suffer loss arising from these registration problems. In addition, the legal remedies in emerging markets are often more limited than the remedies available in the United States. Liquidity/Settlement. Practices pertaining to the settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in large part because of the need to use brokers and counterparties who are less well capitalized, and custody and registration of assets in some countries may be unreliable. As a result, brokerage commissions and other fees are generally higher in emerging markets and the procedures and rules governing foreign transactions and custody may involve delays in payment, delivery or recovery of money or investments. Delays in settlement could result in investment opportunities being missed if the Trust is unable to acquire or dispose of a security. Certain foreign investments may also be less liquid and more volatile than U.S. investments, which may mean at times that such investments are unable to be sold at desirable prices. Political. Political and economic structures in emerging markets often change rapidly, which may cause instability. In adverse social and political circumstances, governments have been involved in policies of expropriation, confiscatory taxation, nationalization, intervention in the securities market and trade settlement, and imposition of foreign investment restrictions and exchange controls, and these could be repeated in the future. In addition to withholding taxes on investment income, some governments in emerging markets may impose different capital gains taxes on foreign investors. Foreign investments may also be subject to the risks of seizure by a foreign government and the imposition of restrictions on the exchange or export of foreign currency. Additionally, some governments exercise substantial influence over the private economic sector and the political and social uncertainties that exist for many developing countries are considerable. Trade. Another risk common to most developing countries is that the economy is heavily export oriented and, accordingly, is dependent upon international trade. The existence of overburdened infrastructures and obsolete financial systems also presents risks in certain countries, as do environmental problems. Certain economies also depend to a large degree upon exports of primary commodities and, therefore, are vulnerable to changes in commodity prices which, in turn, may be affected by a variety of factors. Litigation Tobacco Industry. Certain of the issuers of Securities in the Trust may be involved in the manufacture, distribution and sale of tobacco products. Pending litigation proceedings against such issuers in the United States and abroad cover a wide range of matters including product liability and consumer protection. Damages claimed in such litigation alleging personal injury (both individual and class actions), and in health cost recovery cases brought by governments, labor unions and similar entities seeking reimbursement for healthcare expenditures, aggregate many billions of dollars. In November 1998, five of the largest tobacco companies in the United States entered into the Tobacco Master Settlement Agreement ("MSA") with 46 states to settle state lawsuits to recover costs associated with treating smoking-related illnesses. According to the MSA, the tobacco industry is projected to pay the settling states in excess of $200 billion over the next 25 years. Four states settled their tobacco cases separately from the MSA. In March 2001, five states initiated court proceedings to stop R.J. Reynolds Tobacco Company ("R.J. Reynolds") from violating provisions of the MSA. The lawsuits, filed in state courts of Arizona, California, New York, Ohio and Washington, seek enforcement of restrictions on marketing, advertising and promotional activities that R.J. Reynolds agreed to under the terms of the MSA. In June 2002, a California court ruled that R.J. Reynolds unlawfully placed cigarette ads in magazines with a large percentage of readers aged 12-17, in violation of the MSA. As a result, R.J. Reynolds was ordered to pay $20 million in sanctions plus attorneys' fees and costs. An Arizona court also found R.J. Reynolds had violated the MSA. In July 2004, R.J. Reynolds and Brown & Williamson Tobacco Corporation ("B&W") combined R.J. Reynolds and the U.S. assets, liabilities and operations of B&W to form Reynolds American Inc. On December 15, 2005, the Illinois Supreme Court reversed a $10.1 billion verdict against Altria Group's Philip Morris USA division ("Philip Morris") in what is known as the Price case, ordering a lower court to dismiss the case in which the company was accused of defrauding customers into thinking "light" cigarettes were safer than regular ones. Page 5 The Court held that the Federal Trade Commission specifically authorized the use of "light" and "low tar" to describe the cigarettes, and, therefore, Philip Morris is not liable under Illinois law. The initial $10.1 billion judgment in the Price case was handed down against Philip Morris by a trial court judge in March 2003. The Illinois Supreme Court took the unusual step of bypassing the appellate court in hearing the case on appeal directly from the trial court. The size of the original award put the company at risk for filing bankruptcy protection. In addition, because Philip Morris accounts for more than half of the annual tobacco-settlement payments to the states under the 1998 MSA, such payments could have been in jeopardy. On May 5, 2006 the Illinois Supreme Court denied the plaintiff's motion for a rehearing. In a suit brought by the Department of Justice against Altria and other cigarette companies, a U.S. District Court ruled on August 17, 2006, that the defendants violated the Racketeer Influenced and Corrupt Organizations Act ("RICO"). However, the court refused to grant the $10 billion smoking cessation campaign and $4 billion youth counter- marketing campaign remedies requested by the government. The court did rule that Philip Morris must remove "light" and "ultra light" from its packaging. Altria is appealing this verdict. On July 6, 2006, the Florida Supreme Court decertified a class and overturned a trial court's $145 billion punitive damages award against Philip Morris as excessive and improper as a matter of law. However, Philip Morris also faces several other potential class actions claiming that the marketing of "light" cigarettes deceived people into believing they are healthier, although those cases are not now perceived as a threat given the Price decision. Additional pending and future litigation and/or legislation could adversely affect the value, operating revenues, financial position and sustainability of tobacco companies. The Sponsor is unable to predict the outcome of litigation pending against tobacco companies or how the current uncertainty concerning regulatory and legislative measures will ultimately be resolved. These and other possible developments may have a significant impact upon both the price of such Securities and the value of Units of Trusts containing such Securities.
