(2) Evaluations for purposes of sale, purchase or redemption of Units are made as of the close of trading (generally 4:00 p.m. Eastern time) on the New York Stock Exchange ("NYSE") on each day on which it is open (the "Evaluation Time"). (3) The Public Offering Price shown above reflects the value of the Bonds 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 accrued interest on the Bonds. After the Initial Date of Deposit, the Public Offering Price per Unit will include a pro rata share of any accrued interest on the Bonds. See "Fee Table" and "Public Offering." (4) Until the earlier of six months after the Initial Date of Deposit or the end of the initial offering period, the Sponsor's Initial Repurchase Price per Unit and the Redemption Price per Unit will include the estimated organization costs per Unit set forth under "Fee Table." After such date, the Sponsor's Repurchase Price and Redemption Price per Unit will not include such estimated organization costs. See "Redeeming Your Units." (5) See "Amending or Terminating the Indenture." (6) You may elect to receive distributions either monthly or semi- annually. Distributions will be paid on the last business day of a payment month ("Distribution Date") to Unit holders of record on the fifteenth day of such month ("Distribution Record Date"). The amount of the Estimated Regular Distributions per Unit was calculated on the basis of the Estimated Net Annual Interest Income per Unit less the estimated annual expenses and divided by twelve for monthly distributions or two for semi-annual distributions. The Initial and Partial Distributions per Unit differ from estimated regular distributions because they do not represent a full month or six-month period. Each Unit holder, regardless of the distribution option chosen, will receive the Initial Distribution per Unit on . Semi-annual Unit holders will receive the Partial Distribution per Unit on . Estimated Regular Distributions per Unit will occur monthly, beginning in _________ for monthly Unit holders and will occur each June and December, beginning _________for semi-annual Unit holders. The actual distribution you receive will vary from that set forth above with changes in the Trust's fees and expenses and with the sale or redemption of Bonds. Distributions from the Principal Account will be made monthly if the amount available for distribution equals at least $1.00 per 100 Units. Notwithstanding, distributions of funds in the Principal Account, if any, will be made in December of each year. See "Expenses and Charges" and "Interest and Principal Distributions." (7) Estimated Current Return is calculated by dividing Estimated Net Annual Interest Income per Unit by the Public Offering Price. Estimated Long-Term Return is calculated using a formula which (1) factors in the relative weightings of the market values, yields (which take into account the amortization of premiums and the accretion of discounts) and estimated retirements of the Bonds; and (2) takes into account a compounding factor, the sales charge and expenses. There is no assurance that the Estimated Current and Long-Term Returns set forth above will be realized in the future because the various components used to calculate these figures, such as Trust expenses, market values and estimated retirements of the Bonds, will change. In addition, neither rate reflects the true return you will receive, which will be lower, because neither includes the effect of certain delays in distributions. </FN> Page 3 Fee Table This Fee Table describes the fees and expenses that you may pay if you buy and hold Units of the Trust and receive distributions either monthly or semi-annually. See "Public Offering" and "Expenses and Charges." Although the Trust has a term of approximately _____ years and is a unit investment trust rather than a mutual fund, this information allows you to compare fees. Monthly Semi-Annual Distribution Option Distribution Option ________ ________ Unit Holder Sales Fees (as a percentage of public offering price) Maximum sales charge imposed on purchase % $ % $ ======== ======== ======== ======== Organization Costs (as a percentage of public offering price) Estimated organization costs %(a) $ %(a) $ ======== ======== ======== ======== Estimated Annual Trust Operating Expenses(b) (as a percentage of average net assets) Portfolio supervision, bookkeeping, administrative and evaluation fees % $ % $ Trustee's fee and other operating expenses %(c) %(c) ________ ________ ________ ________ Total % $ % $ ======== ======== ======== ======== This example is intended to help you compare the cost of investing in the Trust with the cost of investing in other investment products. The example assumes that you invest $10,000 in the Trust for the periods shown and sell all your Units at the end of those periods. The example also assumes a 5% return on your investment each year and that the Trust's operating expenses stay the same. The example does not take into consideration transaction fees which may be charged by certain broker/dealers for processing redemption requests. Although your actual costs may vary, based on these assumptions your costs under each distribution option would be: Monthly Semi-Annual Distribution Option Distribution Option ___________ ___________ 1 Year $ $ 3 Years $ $ 5 Years $ $ 10 Years $ $ The example will not differ if you hold rather than sell your Units at the end of each period. ____________ <FN> (a) 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. (b) 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. (c) Other operating expenses include the costs incurred for annually updating the Trust's registration statement, but do not include brokerage costs and other portfolio transaction fees. In certain circumstances the Trust may incur additional expenses not set forth above. See "Expenses and Charges." </FN> Page 4 Report of Independent Auditors The Sponsor, Nike Securities L.P., and Unit Holders The First Trust Combined Series 273 We have audited the accompanying statement of net assets, including the schedule of investments, of The First Trust Combined Series 273, comprising Colorado Insured Series 16 Portfolio (the "Trust"), as of the opening of business on __________, 2002 (Initial Date of Deposit). This statement of net assets is the responsibility of the Trust's Sponsor. Our responsibility is to express an opinion on this statement of net assets based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement of net assets is free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement of net assets. Our procedures included confirmation of the irrevocable letter of credit held by JPMorgan Chase Bank, the Trustee, and deposited in the Trust for the purchase of Securities, as shown in the statement of net assets as of the opening of business on __________, 2002, by correspondence with the Trustee. An audit also includes assessing the accounting principles used and significant estimates made by the Trust's Sponsor, as well as evaluating the overall presentation of the statement of net assets. We believe that our audit of the statement of net assets provides a reasonable basis for our opinion. In our opinion, the statement of net assets referred to above presents fairly, in all material respects, the financial position of The First Trust Combined Series 273, comprising Colorado Insured Series 16 Portfolio, at the opening of business on __________, 2002 (Initial Date of Deposit) in conformity with accounting principles generally accepted in the United States of America.

(2) An irrevocable letter of credit issued by JPMorgan Chase Bank, of which $ will be allocated to the Trust in The First Trust Combined Series 273, has been deposited with the Trustee as collateral, covering the monies necessary for the purchase of the Bonds according to their purchase contracts ($___), accrued interest to the Initial Date of Deposit ($___) and accrued interest from the Initial Date of Deposit to the expected dates of delivery of the Bonds ($___) for Colorado Insured Series 16 Portfolio. (3) The Trustee will advance to the Trust the amount of net interest accrued to the First Settlement Date which will be distributed to the Sponsor as Unit holder of record. (4) A portion of the Public Offering Price consists of an amount sufficient to reimburse the Sponsor for all or a portion of the costs of establishing the Trust. These costs have been estimated at $ per Unit for the Trust. A payment will be made as of the earlier of six months after the Initial Date of Deposit or the end of the initial offering period to an account maintained by the Trustee from which the obligation of the investors to the Sponsor will be satisfied. To the extent that actual organization costs 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. (5) The aggregate cost to investors in the Trust includes a maximum sales charge computed at the rate of % of the Public Offering Price per Unit (equivalent to % of the net amount invested), assuming no reduction of sales charge as set forth under "Public Offering." </FN> Page 6 Schedule of Investments Colorado Insured Series 16 Portfolio The First Trust Combined Series 273 At the Opening of Business on the Initial Date of Deposit-__________, 2002 Aggregate Issue Represented by Sponsor's Redemption Cost of Bonds Principal Contracts to Purchase Bonds (1) Rating (3) Provisions (4) to the Trust (2) __________ _________________________________________ _______ ____________ _________ $ Page 7 Schedule of Investments (cont'd.)

(2) The cost of the Bonds to the Trust represents the aggregate underlying value with respect to the Bonds acquired (generally determined by the aggregate offering price of the Bonds at the Evaluation Time on the business day before the Initial Date of Deposit). The evaluation of the Bonds has been determined by the Evaluator. The cost of the Bonds to the Sponsor and the Sponsor's profit or loss (which is the difference between the cost of the Bonds to the Sponsor and the cost of the Bonds to the Trust) are $ and $ , respectively. In addition, the aggregate bid price of the Bonds at the Evaluation Time on the business day before the Initial Date of Deposit and the annual interest income to the Trust were $ and $ , respectively. (3) Ratings are by Standard & Poor's and/or Moody's Investors Service, Inc. and are unaudited. For a brief description of the rating symbols and their related meanings see "Description of Bond Ratings." Such ratings were obtained from an information reporting service other than Standard & Poor's or Moody's. (4) Certain Bonds may be redeemed before their stated maturity. This column shows when a Security is initially redeemable and the redemption price for that year. Bonds are redeemable at declining prices (but not below par value) in subsequent years. Certain Bonds may also be redeemed in whole or in part other than by operation of the stated redemption provisions under certain circumstance detailed in the instruments creating them. Such redemption provisions may result in a redemption price less than the value of the Bonds on the Initial Date of Deposit. Redemption pursuant to call provisions generally will occur at times when the redeemed Bonds have an offering side valuation which represents a premium over par. To the extent that Bonds were deposited in the Trust at a price higher than the price at which they are redeemed, this will represent a loss of capital when compared with the original Public Offering Price of the Units. Distributions will generally be reduced by the amount of the income which would otherwise have been paid with respect to redeemed Bonds and Unit holders will receive a distribution of the principal amount and any premium received on such redemption (except to the extent the proceeds of the redeemed Bonds are used to pay for Unit redemptions). Estimated Current Return and Estimated Long-Term Return may also be affected by such redemptions. </FN> Page 8 The First Trust Combined Series The First Trust Combined Series Defined. We, Nike Securities L.P. (the "Sponsor"), have created hundreds of similar yet separate series of an investment company which we have named the Combined Series. The series to which this prospectus relates, Combined Series 273, consists of a single portfolio known as Colorado Insured Trust, Series 16. 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 between Nike Securities L.P., as Sponsor, JPMorgan Chase Bank as Trustee, First Trust Advisors L.P. as Portfolio Supervisor and Securities Evaluation Service, Inc. as Evaluator, governs the operation of the Trust. YOU MAY GET MORE SPECIFIC DETAILS ON SOME OF THE INFORMATION IN THIS PROSPECTUS IN AN "INFORMATION SUPPLEMENT" BY CALLING THE TRUSTEE AT 1- 800-682-7520. How We Created the Trust. On the Initial Date of Deposit, we deposited municipal bonds (the "Bonds") with the Trustee and in turn, the Trustee delivered documents to us representing our ownership of the Trust, in the form of units ("Units"). With our deposit of Bonds on the Initial Date of Deposit we established a percentage relationship among the Bonds in the Trust's portfolio, as stated under "Schedule of Investments" for the Trust. After the Initial Date of Deposit, we may deposit additional Bonds in the Trust, 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 Bonds on the Initial Date of Deposit, and not the actual percentage relationship existing on the day we are creating Units, since the two may differ. This difference may be due to the sale, redemption or liquidation of any of the Bonds. Since the prices of the Bonds will fluctuate daily, the ratio of Bonds in the Trust, on a market value basis, will also change daily. The portion of Bonds represented by each Unit will not change as a result of the deposit of additional Bonds in the Trust. We cannot guarantee that the Trust will keep its present size and composition for any length of time. Bonds 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, Bonds 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 Bonds in the Trust. As the holder of the Bonds, the Trustee will vote all of the Bonds and will do so based on our instructions. Neither we nor the Trustee will be liable for a failure in any of the Bonds. However, if a contract for the purchase of any of the Bonds initially deposited in the Trust fails, unless we can purchase substitute Bonds ("Replacement Bonds"), we will refund to you that portion of the purchase price and sales charge resulting from the failed contract on the next Distribution Date. Any Replacement Bond the Trust acquires will be identical to those from the failed contract. Portfolios Objectives. The objective of the Trust is to provide investors with income exempt from federal and Colorado income tax and to preserve capital by investing in tax-exempt municipal bonds issued by or on behalf of the state of Colorado. The Trust has an expected life of ____ years. A diversified portfolio helps to offset the risks normally associated with such an investment, although it does not eliminate them entirely. Of course, as with any similar investments, there can be no guarantee that the objective of the Trust will be achieved. See "Risk Factors" for a discussion of the risks of investing in the Trust. Bond Selection. We considered the following factors, among others, in selecting the Bonds for the Trust: - - The price of the Bonds relative to other issues of similar quality and maturity; - - The present rating and credit quality of the issuer of the Bond and potential for improvement; - - The diversification of the Bonds; - - The income to the Trust; - - Whether the Bonds were issued after __________; and - - The stated maturity of the Bonds. As of the Initial Date of Deposit, all of the Bonds were rated "Aaa" or better by Moody's Investors Service, Inc. ("Moody's"), or "AAA" or better by Standard & Poor's Ratings Services, a division of The McGraw- Hill Companies, Inc. ("Standard & Poor's"). See "Description of Bond Ratings." After the Initial Date of Deposit, a Bond's rating may be lowered. This would not immediately cause the Bond to be removed from Page 9 the Trust, but may be considered by us in determining whether to direct the Trustee to dispose of such Bond. See "Removing Bonds from the Trust." Insurance on the Bonds The Bonds in the Trusts are covered by insurance policies obtained by the issuers or underwriters of the bonds from Ambac, FGIC, FSA or MBIA (the "Insurers"). The "Schedule of Investments" identifies the Insurer of each Bond. Insurance guarantees the timely payment, when due, of all principal and interest on the Bonds. Such insurance is effective so long as the insured Bond is outstanding and the insurer remains in business. Insurance relates only to the particular Bond and not to the Units offered hereby or to their market value. The Bonds have received a rating of "Aaa" by Moody's, and/or "AAA" by Standard & Poor's in recognition of such insurance. There can be no assurance that any Insurer listed will be able to satisfy its commitments in the event claims are made in the future. However, Standard & Poor's, and/or Moody's have rated the claims-paying ability of each Insurer "AAA" or "Aaa" respectively. The following are brief descriptions of the Insurers. Ambac Assurance Corporation. Ambac is a Wisconsin-domiciled stock insurance corporation regulated by the Office of the Commissioner of Insurance of the State of Wisconsin and licensed to do business in all 50 states, the District of Columbia, the Territory of Guam and the Commonwealth of Puerto Rico. Ambac is a wholly-owned subsidiary of Ambac Financial Group, Inc., a 100% publicly-held company. Financial Guaranty Insurance Company. FGIC is a wholly-owned subsidiary of FGIC Corporation (the "Corporation"), a Delaware holding company. The Corporation is a subsidiary of General Electric Capital Corporation ("GE Capital"). Neither the Corporation nor GE Capital is obligated to pay the debts of or the claims against FGIC. FGIC is a monoline financial guaranty insurer domiciled in the State of New York and subject to regulation by the State of New York Insurance Department. FGIC is currently licensed to write insurance in all 50 states and the District of Columbia. Financial Security Assurance Inc. FSA is a monoline insurance company incorporated under the laws of the State of New York. FSA is licensed to engage in the financial guaranty insurance business in all 50 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands. FSA and its subsidiaries are engaged in the business of writing financial guaranty insurance, principally in respect of securities offered in domestic and foreign markets. FSA and its subsidiaries principally insure asset-backed, collateralized and municipal securities. FSA is a wholly-owned subsidiary of Financial Security Assurance Holdings Ltd. ("Holdings"). Holdings is an indirect subsidiary of Dexia, S.A., a publicly held Belgian corporation. MBIA Insurance Corporation. MBIA is the principal operating subsidiary of MBIA Inc., a New York Stock Exchange listed company. MBIA Inc. is not obligated to pay the debts of or claims against MBIA. MBIA is domiciled in the State of New York and is licensed to do business in and subject to regulation under the laws of all 50 states, the District of Columbia, the Commonwealth of Puerto Rico, the Commonwealth of the Northern Mariana Islands, the Virgin Islands of the United States and the Territory of Guam. MBIA has two European branches, one in the Republic of France and the other in the Kingdom of Spain. Insurance companies are subject to extensive regulation and supervision where they do business by state insurance commissioners who regulate the standards of solvency which must be maintained, the nature of and limitations on investments, reports of financial condition, and requirements regarding reserves for unearned premiums, losses and other matters. A significant portion of the assets of insurance companies is required by law to be held in reserve against potential claims on policies and is not available to general creditors. Although the federal government does not regulate the business of insurance, federal initiatives including pension regulation, controls on medical care costs. minimum standards for no-fault automobile insurance, national health insurance, tax law changes affecting life insurance companies and repeal of the antitrust exemption for the insurance business can significantly impact the insurance business. The above ratings are not recommendations to buy, sell or hold the Bonds, and such ratings may be subject to revision or withdrawal at any time by the rating agencies. Any downward revision or withdrawal of either or both ratings my have an adverse effect on the market price of the Bonds. Because the insurance on the Bonds, if any, will be effective so long as the Bonds are outstanding, such insurance will be taken into account in determining the market value of the Bonds and therefore some value attributable to such insurance will be included in the value of the Units of the Insured Portfolios. The insurance does not, however, guarantee the market value of the Bonds or of the Units. Page 10 Risk Factors Price Volatility. The Trust invests in municipal bonds. The value of the Bonds will decline 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. The value of the Bonds will also fluctuate with changes in investors' perceptions of an issuer's financial condition or the general condition of the municipal bond market, changes in inflation rates or when political or economic events affecting the issuers occur. Because the Trust is not managed, the Trustee will not sell Bonds 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. Interest. There is no guarantee that the issuers of the Bonds will be able to satisfy their interest payment obligations to the Trust over the life of the Trust. Alternative Minimum Tax. While distributions of interest from the Trust are generally exempt from federal income taxes, a portion of such interest may be taken into account in computing the alternative minimum tax. Municipal Bonds. The Trust invests in tax-exempt municipal bonds. Municipal bonds are debt obligations issued by states or political subdivisions or authorities of states. Municipal bonds are typically designated as general obligation bonds, which are general obligations of a governmental entity that are backed by the taxing power of such entity, or revenue bonds, which are payable from the income of a specific project or authority and are not supported by the issuer's power to levy taxes. Municipal bonds are long-term fixed rate debt obligations that generally decline in value with increases in interest rates, when an issuer's financial condition worsens or when the rating on a bond is decreased. Many municipal bonds may be called or redeemed prior to their stated maturity, an event which is more likely to occur when interest rates fall. In such an occurrence, you may not be able to reinvest the money you receive in other bonds that have as high a yield or as long a maturity. Many municipal bonds are subject to continuing requirements as to the actual use of the bond proceeds or manner of operation of the project financed from bond proceeds that may affect the exemption of interest on such bonds from federal income taxation. The market for municipal bonds is generally less liquid than for other securities and therefore the price of municipal bonds may be more volatile and subject to greater price fluctuations than securities with greater liquidity. In addition, an issuer's ability to make income distributions generally depends on several factors including the financial condition of the issuer and general economic conditions. Any of these factors may negatively impact the price of municipal bonds held by the Trust and would therefore impact the price of both the Bonds and the Units. Acts of terrorism and any resulting damage may not be covered by insurance on the bonds. Issuers of the bonds may therefore be at risk of default due to losses sustained as a result of terrorist activities. Colorado. Because the Trust is concentrated in the bonds of issuers located in the State of Colorado, there may be more risk than if the bonds were issued by issuers located in several states. The financial condition of Colorado is affected by various national and local, economic, social and environmental policies and conditions and may have an effect on the value of the Units. Additionally, Constitutional and statutory limitations imposed on the State and its local governments concerning taxes, bond indebtedness and other matters may constrain the revenue-generating capacity of the State and its local governments and, therefore, the ability of the issuers of the bonds to satisfy their obligations. Historically, the State experienced significant revenue shortfalls. A somewhat ambiguous Constitutional Amendment requires voter approval prior to tax increases, creation of debt, or mill levy or valuation for assessment ratio increases. The Amendment also limits increases in government spending and property tax revenues to specified percentages. The economy of the State continues to be dependent on tourism and its position as a transportation hub. These sectors tend to be cyclical. In addition, the State is party to numerous lawsuits in which an adverse final decision could materially affect the State's governmental operations and consequently its ability to pay debt service on its obligations. Legislation/Litigation. From time to time, various legislative initiatives are proposed which may have a negative impact on the prices of certain of the municipal bonds represented in the Trust. In addition, Page 11 litigation regarding any of the issuers of the municipal bonds, such as litigation affecting the validity of certain municipal bonds or the tax- free nature of the interest thereon, may negatively impact the share prices of these Bonds. We cannot predict what impact any pending or proposed legislation or pending or threatened litigation will have on the prices of the Bonds or of the issuers. Public Offering The Public Offering Price. You may buy Units at the Public Offering Price, the price per Unit of which is comprised of the following: - - The aggregate underlying value of the Bonds; - - The amount of any cash in the Interest and Principal Accounts of the Trust; - - Net interest accrued but unpaid on the Bonds after the First Settlement Date to the date of settlement; and - - The sales charge. The price you pay for your Units will differ from the amount stated under "Summary of Essential Information" due to various factors, including fluctuations in the prices of the Bonds, changes in the value of the Interest and/or Principal Accounts and the accrual of interest on the Bonds. 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. Bonds purchased with the portion of the Public Offering Price intended to be used to reimburse the Sponsor for the Trust's organization costs (including costs of preparing the registration statement, the Indenture and other closing documents, registering Units with the Securities and Exchange Commission ("SEC") and states, the initial audit of the Trust portfolio, legal fees and the initial fees and expenses of the Trustee) will be purchased in the same proportionate relationship as all the Bonds contained in the Trust. Bonds 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 Bonds. To the extent the proceeds from the sale of these Bonds are insufficient to repay the Sponsor for the Trust organization costs, the Trustee will sell additional Bonds to allow the Trust to fully reimburse the Sponsor. In that event, the net asset value per Unit will be reduced by the amount of additional Bonds sold. Although the dollar amount of the reimbursement will remain fixed and will never exceed the per Unit amount set forth in "Notes to Statement of Net Assets" for the Trust, this will result in a greater effective cost per Unit to Unit holders for the reimbursement to the Sponsor. To the extent actual organization costs are less than the estimated amount, only the actual organization costs will be deducted from the assets of the Trust. When Bonds are sold to reimburse the Sponsor for organization costs, the Trustee will sell such Bonds, to the extent practicable, which will maintain the same proportionate relationship among the Bonds contained in the Trust as existed prior to such sale. Accrued Interest. Accrued interest represents unpaid interest on a bond from the last day it paid interest. Interest on the Bonds generally is paid semiannually, although the Trust accrues such interest daily. Because the Trust always has an amount of interest earned but not yet collected, the Public Offering Price of Units will have added to it the proportionate share of accrued interest to the date of settlement. You will receive the amount, if any, of accrued interest you paid for on the next distribution date. In addition, if you sell or redeem your Units you will be entitled to receive your proportionate share of accrued interest from the purchaser of your Units. Minimum Purchase. The minimum amount you can purchase of the Trust is $1,000 worth of Units ($500 if you are purchasing Units for your Individual Retirement Account or any other qualified retirement plan). Sales Charges. Initial Offering Period. The maximum sales charge during the initial offering period equals % of the Public Offering Price (equivalent to % of the net amount invested). Secondary Market. The maximum sales charge during the secondary market is determined based upon the number of years remaining to the maturity of each Bond in the Trust, but in no event will the secondary market sales charge exceed % of the Public Offering Price (equivalent to % of the net amount invested). For purposes of computation, Bonds will be deemed to mature either on their expressed maturity dates, or an Page 12 earlier date if: (a) they have been called for redemption or funds have been placed in escrow to redeem them on an earlier call date; or (b) such Bonds are subject to a "mandatory tender." The effect of this method of sales charge computation will be that different sales charge rates will be applied to each of the Bonds, in accordance with the following schedule: Secondary Market Years to Maturity Sales Charge _________________ ________________ Less than 1 % 1 but less than 2 % 2 but less than 3 % 3 but less than 4 % 4 but less than 5 % 5 but less than 6 % 6 but less than 7 % 7 but less than 8 % 8 or more % Discounts for Certain Persons. If you invest at least $ (except if you are purchasing for a "wrap fee account" as described below), the maximum sales charge is reduced, as follows: Your maximumsales If you invest charge (in thousands):* will be: ______________ ____________ $ but less than $ % $ but less than $ % $ but less than $ % $ or more % * Breakpoint sales charges are also applied on a Unit basis utilizing a breakpoint equivalent in the above table of $10 per Unit and will be applied on whichever basis is more favorable to the investor. The breakpoints will be adjusted to take into consideration purchase orders stated in dollars which cannot be completely fulfilled due to the requirement that only whole Units be issued. The reduced sales charge for quantity purchases will apply only to purchases made by the same person on any one day from any one dealer. We will consider Units you purchase in the name of your spouse or child under 21 years of age to be purchases by you for determining the reduced sales charge. The reduced sales charges will also apply to a trustee or other fiduciary purchasing Units for a single trust estate or single fiduciary account. You must inform your dealer of any combined purchases before the sale in order to be eligible for the reduced sales charge. Any reduced sales charge is the responsibility of the party making the sale. The following persons may purchase Units at the Public Offering Price less the applicable dealer concession: - - Employees, officers and directors of the Sponsor, our related companies, dealers and their affiliates, and vendors providing services to us. - - Immediate family members of the above (spouses, children, grandchildren, parents, grandparents, siblings, mothers-in-law, fathers- in-law, sons-in-law and daughters-in-law, and trustees, custodians or fiduciaries for the benefit of such persons). If you purchase Units through registered broker/dealers who charge periodic fees for financial planning, investment advisory or asset management services or provide these services as part of an investment account where a comprehensive "wrap fee" charge is imposed, you may purchase Units at the Public Offering Price, subject only to the Sponsor's retention of the sales charge. See "Distribution of Units- Dealer Concessions." The Value of the Bonds. The Evaluator will appraise the aggregate underlying value of the Bonds 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 holidays on which the NYSE is closed. The aggregate underlying value of the Bonds in the Trust will be determined as follows: a) On the basis of current market offering prices for the Bonds obtained from dealers or brokers who customarily deal in bonds comparable to those held by the Trust; b) If such prices are not available for any of the Bonds, on the basis of current market offering prices of comparable bonds; c) By determining the value of the Bonds on the offering side of the market by appraisal; or d) By any combination of the above. After the initial offering period is over, the aggregate underlying value of the Bonds will be determined as set forth above, except that bid prices are used instead of ask prices when necessary. The offering price of the Bonds may be expected to be greater than their bid price by Page 13 approximately 1-2% of the aggregate principal amount of such Bonds. 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 current Public Offering Price. Dealer Concessions. Dealers and other selling agents can purchase Units at prices which reflect a concession or agency commission of % of the Public Offering Price per Unit (or % of the maximum sales charge for secondary market sales). Dealers and selling agents will receive an additional volume concession or agency commission of % of the Public Offering Price if they purchase at least $_______ worth of Units of the Trust on the Initial Date of Deposit or $________ on any day thereafter or if they were eligible to receive a similar concession in connection with sales of similarly structured trusts sponsored by us which are currently in the initial offering period. 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 sales charge paid by these customers is kept by or given to the banks in the amounts shown above. Award Programs. From time to time we may sponsor programs which provide awards to our dealers' registered representatives who have sold a minimum number of Units during a specified time period. We may also pay fees to qualifying dealers for services or activities which are meant to result in sales of Units of the Trust. In addition, we will pay to dealers who sponsor sales contests or recognition programs that conform to our criteria or participate in our sales programs, amounts equal to no more than the total applicable sales charges on Units sold by such persons during such programs. We make these payments out of our own assets and not out of Trust assets. These programs will not change the price you pay for your Units. Advertising and Investment Comparisons. Advertising materials regarding the Trust may discuss several topics, including: developing a long-term financial plan; working with your financial professional; the nature and risks of various investment strategies and unit investment trusts that could help you reach your financial goals; the importance of discipline; how the Trust operates; how securities are selected; various unit investment trust features such as convenience and costs; and options available for certain types of unit investment trusts. These materials may include descriptions of the 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 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 or tax-exempt investments such as the securities comprising various investment indices, 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, Business Week, Forbes or Fortune. The investment characteristics of the Trust, which are described more fully elsewhere in this prospectus, differ from other comparative investments. You should not assume that these performance comparisons will be representative of the Trust's future performance. The Sponsor's Profits We will receive a gross sales commission equal to the maximum sales charge per Unit for the Trust less any reduction as stated in "Public Offering." Also, any difference between our cost to purchase the Bonds 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. Page 14 We will pay all expenses to maintain a secondary market, except the Evaluator fees, Trustee costs to transfer and record the ownership of Units and costs incurred in annually updating the Trust's registration statement. We may discontinue purchases of Units at any time. IF YOU WISH TO DISPOSE OF YOUR UNITS, YOU SHOULD ASK US FOR THE CURRENT MARKET PRICES BEFORE MAKING A TENDER FOR REDEMPTION TO THE TRUSTEE. How We Purchase Units The Trustee will notify us of any tender of Units for redemption. If our bid at that time is equal to or greater than the Redemption Price per Unit, we may purchase the Units. You will receive your proceeds from the sale no later than if they were redeemed by the Trustee. We may tender Units we hold to the Trustee for redemption as any other Units. If we elect not to purchase Units, the Trustee may sell Units tendered for redemption 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 of the Trust exceed the estimate, the Trust will bear the excess. The Trustee will pay operating expenses of the Trust from the Interest Account of the Trust if funds are available, and then from the Principal Account. The Interest and Principal Accounts are noninterest-bearing to Unit holders, so the Trustee may earn interest on these funds, thus benefiting from their use. First Trust Advisors L.P., an affiliate of ours, will be compensated for providing bookkeeping and other administrative services to the Trust, and, as Sponsor, we will receive brokerage fees when the Trust uses us (or an affiliate of ours) as agent in buying or selling Bonds. Legal, typesetting, electronic filing and regulatory filing fees and expenses associated with updating the Trust's registration statement yearly are now chargeable to the Trust. In addition, First Trust Advisors L.P. acts as Portfolio Supervisor to the Trust and will receive the fees set forth under "Fee Table" for providing portfolio supervisory 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. The fees payable to the Portfolio Supervisor, Evaluator and 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 affiliate for providing services to all unit investment trusts be more than the actual cost of providing such services in such year. In addition to the Trust's operating expenses, and the fees set forth above, the Trust may also incur the following charges: - - All legal and annual auditing expenses of the Trustee according to its responsibilities under the Indenture; - - The expenses and costs incurred by the Trustee to protect the Trust and your rights and interests; - - Fees for any extraordinary services the Trustee performed under the Indenture; - - Payment for any loss, liability or expense the Trustee incurred without negligence, bad faith or willful misconduct on its part, in connection with its acceptance or administration of the Trust; - - Payment for any loss, liability or expenses we incurred without negligence, bad faith or willful misconduct in acting as Depositor of the Trust; and/or - - All taxes and other government charges imposed upon the Bonds or any part of the Trust. The above expenses and the Trustee's annual fee are secured by a lien on the Trust. We cannot guarantee that distributions from the Bonds will be sufficient to meet any or all expenses of the Trust. If there is not enough cash in the Interest or Principal Accounts of the Trust, the Trustee has the power to sell Bonds to make cash available to pay these charges. These sales may result in capital gains or losses to the Unit holders. See "Tax Status." The Trust will be audited annually. So long as we are making a secondary market for Units, we will bear the cost of these annual audits to the extent the cost exceeds $0.0050 per Unit. Otherwise, the Trust will pay for the audit. You can request a copy of the audited financial statements from the Trustee. Tax Status State Tax Status. The assets of each Colorado Trust will consist of interest-bearing obligations issued by or on behalf of the State of Colorado ("Colorado") Page 15 or counties, municipalities, authorities or political subdivisions thereof (the "Colorado Bonds") the interest on which is expected to qualify as exempt from Colorado income taxes. Neither the Sponsor nor its counsel have independently examined the Bonds to be deposited and held in each Trust. However, it has assumed that: (i) the Bonds were validly issued, (ii) the interest thereon is excludable from gross income for Federal income tax purposes, and (iii) interest on the Bonds, if received directly by a Unit holder, would be exempt from the income tax imposed by the State that is applicable to individuals and corporations. This opinion does not address the taxation of persons other than full time residents of Colorado. It is assumed that, at the respective times of issuance of the Bonds, opinions relating to the validity thereof and to the exemption of interest thereon from Federal income tax were rendered by bond counsel to the respective issuing authorities. In addition, it is assumed that, with respect to the Colorado Bonds, bond counsel to the issuing authorities rendered opinions that the interest on the Colorado Bonds is exempt from the Colorado Income Tax. Neither the Sponsor nor its counsel has made any review for the Colorado Trust of the proceedings relating to the issuance of the Bonds or of the bases for the opinions rendered in connection therewith. Because Colorado income tax law is based upon the Federal law, the Trust is not an association taxable as a corporation for purposes of Colorado income taxation. With respect to Colorado Unit holders, in view of the relationship between Federal and Colorado tax computations described above: (i) each Colorado Unit holder will be treated as owning a pro rata share of each asset of a Colorado Trust for Colorado income tax purposes in the proportion that the number of Units of such Trust held by the Unit holder bears to the total number of outstanding Units of a Colorado Trust, and the income of a Colorado Trust will therefore be treated as the income of each Colorado Unit holder under Colorado law in the proportion described and an item of income of the Colorado Trust will have the same character in the hands of a Colorado Unit holder as it would have if the Colorado Unit holder directly owned the assets of a Colorado Trust; (ii) interest on Bonds that would not be includable in income for Colorado income tax purposes when paid directly to a Colorado Unit holder will be exempt from Colorado income taxation when received by a Colorado Trust and attributed to such Colorado Unit holder and when distributed to such Colorado Unit holder; (iii) any proceeds paid under an insurance policy or policies, if any, issued to a Colorado Insured Trust with respect to the Bonds in a Colorado Trust which represent maturing interest on defaulted Bonds held by the Trustee will be excludable from Colorado adjusted gross income if, and to the same extent as, such interest is so excludable for federal income tax purposes if paid in the normal course by the issuer notwithstanding that the source of payment is from insurance proceeds provided that, at the time such policies are purchased, the amounts paid for such policies are reasonable, customary, and consistent with the reasonable expectation that the issuer of the Bonds, rather than the insurer, will pay debt service on the Bonds; (iv) each Colorado Unit holder will realize taxable gain or loss when a Colorado Trust disposes of a Bond (whether by sale, exchange, redemption, or payment at maturity) or when the Colorado Unit holder redeems or sells Units at a price that differs from original cost as adjusted for amortization of bond discount or premium and other basis adjustments (including any basis reduction that may be required to reflect a Colorado Unit holder's share of interest, if any, accruing on Bonds during the interval between the Colorado Unit holder's settlement date and the date such Bonds are delivered to a Colorado Trust, if later); (v) tax basis reduction requirements relating to amortization of bond premium may, under some circumstances, result in Colorado Unit holders realizing taxable gain when their Units are sold or redeemed for an amount equal to or less than their original cost; and (vi) if interest on indebtedness incurred or continued by a Colorado Unit holder to purchase Units in a Colorado Trust is not deductible for federal income tax purposes, it also will be non-deductible for Colorado income tax purposes. Unit holders should be aware that all tax-exempt interest, including their share of interest on the Bonds paid to a Colorado Trust, is taken into account for purposes of determining eligibility for the Colorado Property Tax/Rent/Heat Rebate. Ownership of the Units may result in collateral Colorado tax consequences to certain taxpayers. Prospective investors should consult with tax advisors as to the applicability of any such collateral consequences.Federal Tax Status. Federal Tax Status. This section summarizes some of the main U.S. federal income tax consequences of owning Units of the Trust. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a non-U.S. person, a broker/dealer, or other investor with special circumstances. In addition, this section does not describe your state or foreign taxes. Page 16 As with any investment, you should consult your own tax professional about your particular consequences. In addition, the Internal Revenue Service issued new withholding and reporting regulations effective January 1, 2001. Foreign investors should consult their own tax advisors regarding the tax consequences of these regulations. Assets of the Trust. The Trust will hold various debt obligations (the "Bonds") of state and local governmental entities. All of the assets held by a Trust constitute the "Trust Assets." For purposes of this federal tax discussion, it is assumed that the Bonds constitute debt the interest on which is excluded from gross income for federal income tax purposes. Trust Status. The Trust will not be taxed as a corporation for federal income tax purposes. As a Unit owner, you will be treated as the owner of a pro rata portion of the assets of your trust, and as such you will be considered to have received a pro rata share of income (e.g., accruals of market discount and capital gains, if any) from the Trust Assets when such income would be considered to be received by you if you directly owned the Trust Assets. This is true even if you elect to have your distributions automatically reinvested into additional Units. In addition, the income from the Trust Assets which you must take into account for federal income tax purposes is not reduced by amounts used to pay Trust expenses (including the deferred sales charge, if any). Exclusion from Gross Income of Interest. At the respective times of issuance of the Bonds, opinions relating to the validity thereof and to the exclusion of interest thereon from Federal gross income were rendered by bond counsel to the respective issuing authorities, based on certain representations and subject to compliance with certain covenants. In addition, with respect to a State Trust, where applicable, bond counsel to the issuing authorities rendered opinions as to the exemption of interest on such Bonds when held by residents of the State in which the issuers of such Bonds are located, from State income taxes and certain state or local intangibles and local income taxes. Neither the Sponsor, its counsel, nor any of the Special Counsel to the Fund for State tax matters have made any special review for the Fund of the proceedings relating to the issuance of the Bonds, the bases for the bond counsel opinions, or compliance with the covenants required for tax-exemption. The Internal Revenue Service (the "Service") has an ongoing program of auditing tax-exempt obligations to determine whether, in the view of the Service, interest on such tax- exempt obligations is includible in the gross income of the owners thereof for federal income tax purposes. It cannot be predicted whether or not the Service will commence an audit of any of the Bonds. If an audit is commenced, under current procedures of the Service, Unitholders may have no right to participate in such procedure. If the interest on a Bond should be determined to be taxable, the Bond would generally have to be sold at a substantial discount. In addition, investors could be required to pay income tax on interest received both prior to and after the date on which interest is determined to be taxable. Your pro rata share of interest on the Bonds will be excluded from your gross income for federal income tax purposes to the same extent that such interest would be excluded from your gross income if you directly owned the Bonds. However, such interest may be taken into account in computing the alternative minimum tax, and the branch profits tax imposed on certain foreign corporations. Ownership of the Units may result in collateral federal income tax consequences to certain Unitholders, including, without limitation, corporations subject to the branch profits tax, financial institutions, certain insurance companies, certain S corporations, individual recipients of Social Security or Railroad Retirement benefits and Unitholders who may be deemed to have incurred (or continued) indebtedness to purchase or carry tax-exempt obligations. If you are a "substantial user" of the facilities financed with the proceeds of certain Bonds, or a related person to a substantial user, you will not be able to exclude from your gross income interest with respect to these Bonds. "Substantial user" and "related person" are defined under federal income tax law. For purposes of computing the alternative minimum tax for individuals and corporations, interest on certain bonds is included as an item of tax preference. EXCEPT AS OTHERWISE PROVIDED, THE TRUST DOES NOT INCLUDE ANY SUCH BONDS. In the case of certain corporations, the alternative minimum tax depends upon the corporation's alternative minimum taxable income ("AMTI"), which is the corporation's taxable income with certain adjustments. One of the adjustment items used in computing AMTI of a corporation (excluding S Corporations, Regulated Investment Companies, Real Estate Investment Trusts, REMICs or FASITs) is an amount equal to 75% of the excess of such corporation's "adjusted current earnings" over an amount equal to its AMTI (before such adjustment item and the alternative tax net operating loss deduction). "Adjusted current earnings" includes all tax-exempt interest, including interest on all of the Bonds in the Trust. In addition, a branch profits tax is levied on the "effectively Page 17 connected earnings and profits" of certain foreign corporations, which include tax-exempt interest, such as interest on the Bonds in the Trust. Your Tax Basis and Income or Loss Upon Disposition. If your Trust disposes of Trust Assets, you will generally recognize gain or loss. If you dispose of your Units or redeem your Units for cash, you will also generally recognize gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in the related Trust Assets from your share of the total amount received in the transaction. You can generally determine your initial tax basis in each Trust Asset by apportioning the cost of your Units, generally including sales charges, among each Trust Asset ratably according to their value on the date you purchase your Units. In certain circumstances, however, you may have to adjust your tax basis after you purchase your Units (for example, in the case of accruals of original issue discount, market discount, premium and accrued interest, as discussed below). If you are an individual, the maximum marginal federal tax rate for net capital gain is generally 20% (10% for certain taxpayers in the 10% and 15% tax brackets). The 20% rate is reduced to 18% and the 10% rate is reduced to 8% for long-term gains from most property acquired after December 31, 2000, with a holding period of more than five years. Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your Units to determine your holding period. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code, however, treats certain capital gains as ordinary income in special situations. Discount, Accrued Interest and Premium on Debt Obligations. Some Bonds may have been sold with original issue discount. This generally means that the Bonds were originally issued at a price below their face (or par) value. Original issue discount accrues on a daily basis and generally is treated as interest income for federal income tax purposes. Thus, the accrual of original discount will be excluded from your gross income for federal income tax purposes to the same extent as interest on the Bonds, as discussed above. Your basis of each Bond which was issued with original issue discount must be increased as original issue discount accrues. Some Bonds may have been purchased by you or the Trust at a market discount. Market discount is generally the excess of the stated redemption price at maturity for the Bonds over the purchase price of the Bond. Market discount can arise based on the price a Trust pays for a Bond or on the price you pay for your Units. Market discount is taxed as ordinary income. You will recognize this income when your Trust receives principal payments on the Bond, when the Bond is disposed of or redeemed, or when you sell or redeem your Units. Alternatively, you may elect to include market discount in taxable income as it accrues. Whether or not you make this election will affect how you calculate your basis and the timing of certain interest expense deductions. Alternatively, some Bonds may have been purchased by you or your Trust at a premium. Generally, if the tax basis of your pro rata portion of any Bond, generally including sales charges, exceeds the amount payable at maturity, such excess is considered premium. You must amortize bond premium on a constant yield basis over the remaining term of the Bond in a manner that takes into account potential call dates and call prices. You cannot deduct amortized bond premium relating to a Bond. The amortized bond premium is treated as a reduction in the tax-exempt interest received. As bond premium is amortized, it reduces your basis in the Bond. The tax basis reduction requirement may result in your realizing a taxable gain when your Units are sold or redeemed for an amount equal to or less than your cost. If the price of your Units includes accrued interest on a Bond, you must include the accrued interest in your tax basis in that Bond. When your Trust receives this accrued interest, you must treat it as a return of capital and reduce your tax basis in the Bond. This discussion provides only the general rules with respect to the tax treatment of original issue discount, market discount and premium. The rules, however, are complex and special rules apply in certain circumstances. For example, the accrual of market discount or premium may differ from the discussion set forth above in the case of Bonds that were issued with original issue discount. Exchanges and Rollovers. If you elect to reinvest amounts received from the Trust into a future trust, it is considered a sale for federal income tax purposes, and any gain on the sale will be treated as a capital gain, and any loss will be treated as a capital loss. However, any loss you incur in connection with the exchange of your Units of your Trust for units of a future trust will generally be disallowed with respect to this deemed sale and subsequent deemed repurchase, to the extent the two trusts have Page 18 substantially identical assets under the wash sale provisions of the Internal Revenue Code. Limitations on the Deductibility of Trust Expenses. Generally, for federal income tax purposes, you must take into account your full pro rata share of your Trust's income, even if some of that income is used to pay Trust expenses. You may deduct your pro rata share of each expense paid by the Trust to the same extent as if you directly paid the expense. You may, however, be required to treat some or all of the expenses of your Trust as miscellaneous itemized deductions. Individuals may only deduct certain miscellaneous itemized deductions to the extent they exceed 2% of adjusted gross income. Your ability to deduct Trust expenses is also limited to the extent the expenses are allocable to tax-exempt interest from the Trust. 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. If you are considering participating in a plan like this, you should review the tax laws regarding these plans and consult your attorney or tax adviser. Brokerage firms and other financial institutions offer these plans with varying fees and charges. Rights of Unit Holders Unit Ownership. The Trustee will treat as Record Owner of Units persons registered as such on its books. It is your responsibility to notify the Trustee when you become Record Owner, but normally your broker/dealer provides this notice. You may elect to hold your Units in either certificated or uncertificated form. Certificated Units. When you purchase your Units you can request that they be evidenced by certificates, which will be delivered shortly after your order. Certificates will be issued in fully registered form, transferable only on the books of the Trustee in denominations of one Unit or any multiple thereof. You can transfer or redeem your certificated Units by endorsing and surrendering the certificate to the Trustee, along with a written instrument of transfer. You must sign your name exactly as it appears on the face of the certificate with your signature guaranteed by an eligible institution. In certain cases the Trustee may require additional documentation before they will transfer or redeem your Units. You may be required to pay a nominal fee to the Trustee for each certificate reissued or transferred, and to pay any government charge that may be imposed for each transfer or exchange. If a certificate gets lost, stolen or destroyed, you may be required to furnish indemnity to the Trustee to receive replacement certificates. You must surrender mutilated certificates to the Trustee for replacement. Uncertificated Units. You may also choose to hold your Units in uncertificated form. If you choose this option, the Trustee will establish an account for you and credit your account with the number of Units you purchase. Within two business days of the issuance or transfer of Units held in uncertificated form, the Trustee will send you: - - A written initial transaction statement containing a description of your Trust; - - 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 will provide you with a statement detailing the per Unit amount of interest (if any) distributed. After the end of each calendar year, the Trustee will provide you with the following information: - - The amount of interest received by the Trust less deductions for payment of applicable taxes, fees and Trust expenses, redemption of Units and the balance remaining on the last business day of the calendar year; - - The dates Bonds were sold and the net proceeds received from such sales less deduction for payment of applicable taxes, fees and Trust expenses, redemption of Units and the balance remaining on the last business day of the calendar year; Page 19 - - The Bonds held and the number of Units outstanding on the last business day of the calendar year; - - The Redemption Price per Unit on the last business day of the calendar year; and - - The amounts actually distributed during the calendar year from the Interest and Principal Accounts, separately stated. You may request from the Trustee copies of the evaluations of the Bonds as prepared by the Evaluator to enable you to comply with federal and state tax reporting requirements. Interest and Principal Distributions You will begin receiving distributions on your Units only after you become a Record Owner. The Trustee will credit interest received on the Trust's Bonds to the Interest Account of the Trust. All other receipts, such as return of capital, are credited to the Principal Account of the Trust. After deducting the amount of accrued interest the Trustee advanced to us as Unit holder of record as of the First Settlement Date, the Trustee will distribute an amount substantially equal to your pro rata share of the balance of the Interest Account calculated on the basis of one- twelfth (one-half in the case of Unit holders electing semi-annual distributions) of the estimated annual amount of interest received in the Income Account after deducting estimated expenses on or near the Distribution Dates to Unit holders of record on the preceding Distribution Record Date. See "Summary of Essential Information" for the Trust. Because interest is not received by the Trust at a constant rate throughout the year, the distributions you receive may be more or less than the amount credited to the Interest Account as of the Distribution Record Date. In order to minimize fluctuations in distributions, the Trustee is authorized to advance such amounts as may be necessary to provide distributions of approximately equal amounts. The Trustee will be reimbursed, without interest, for any such advances from funds in the Interest Account at the next Distribution Record Date. The Trustee will distribute amounts in the Principal Account on the last day of each month to Unit holders of record on the fifteenth day of each month provided the amount equals at least $1.00 per 100 Units. If the Trustee does not have your TIN, it is required to withhold a certain percentage of your distribution and deliver such amount to the Internal Revenue Service ("IRS"). You may recover this amount by giving your TIN to the Trustee, or when you file a tax return. However, you should check your statements to make sure the Trustee has your TIN to avoid this "back-up withholding." You will receive interest distributions monthly unless you elect to receive them semi-annually. Your plan of distribution will remain in effect until changed. During May of each year the Trustee will provide you with information on how to change your distribution election. Within a reasonable time after the Trust is terminated you will receive the pro rata share of the money from the disposition of the Bonds. 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. Universal Distribution Option. You may elect to have your principal and interest distributions automatically distributed to any other investment vehicle of which you have an existing account. If you elect this option, the Trustee will notify you of each distribution made pursuant to this option. You may elect to terminate your participation at any time by notifying the Trustee in writing. Redeeming Your Units You may redeem all or a portion of your Units at any time by sending the certificates representing the Units you want to redeem to the Trustee at its unit investment trust office. If your Units are uncertificated, you need only deliver a request for redemption to the Trustee. In either case, the certificates or the redemption request must be properly endorsed with proper instruments of transfer and signature guarantees as explained in "Rights of Unit Holders-Unit Ownership" (or by providing satisfactory indemnity if the certificates were lost, stolen, or destroyed). No redemption fee will be charged, but you are responsible for any governmental charges that apply. Certain broker/dealers may charge a transaction fee for processing redemption requests. Units redeemed directly through the Trustee are not subject to such transaction fees. Three business days after the day you tender your Units (the "Date of Tender") you will receive cash in an amount for each Unit equal to the Redemption Price per Unit calculated at the Evaluation Time on the Date of Tender. The Date of Tender is considered to be the date on which the Trustee receives your certificates or redemption request (if such day is a day the NYSE is open for trading). However, if your certificates or Page 20 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 interest will be withdrawn from the Interest Account of the Trust if funds are available for that purpose, or from the Principal Account. All other amounts paid on redemption will be taken from the Principal Account of the Trust. The IRS requires the Trustee to withhold a portion of your redemption proceeds if the Trustee does not have your TIN, as generally discussed under "Income and Capital Distributions." The Trustee may sell Bonds in the Trust to make funds available for redemption. If Bonds are sold, the size and diversification of the Trust will be reduced. These sales may result in lower prices than if the Bonds 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 Bonds 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 Interest and Principal Accounts of the Trust not designated to purchase Bonds; 2. the aggregate underlying value of the Bonds held in the Trust; and 3. accrued interest on the Bonds; and deducting 1. any applicable taxes or governmental charges that need to be paid out of the Trust; 2. any amounts owed to the Trustee for its advances; 3. estimated accrued expenses of the Trust, if any; 4. cash held for distribution to Unit holders of record of the Trust as of the business day before the evaluation being made; and 5. other liabilities incurred by the Trust; and dividing 1. the result by the number of outstanding Units of the Trust. 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 Bonds 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 Bond in certain limited circumstances, including situations in which: - - The issuer of the Bond has defaulted in the payment of principal or interest on the Bond; - - Any action or proceeding seeking to restrain or enjoin the payment of principal or interest on the Bond has been instituted; - - The issuer of the Bond has breached a covenant which would affect the payment of principal or interest on the Bond, the issuer's credit standing, or otherwise damage the sound investment character of the Bond; - - The issuer has defaulted on the payment of any other of its outstanding obligations; - - The Bond is the subject of an advanced refunding; - - Such factors arise which, in our opinion, adversely affect the tax or exchange control status of the Bond; or - - The price of the Bond has declined to such an extent, or such other credit factors exist, that in our opinion keeping the Bond would be harmful to the Trust. If a Bond defaults in the payment of principal or interest and no provision for payment is made, the Trustee must notify us of this fact within 30 days. If we fail to instruct the Trustee whether to sell or hold the Bond within 30 days of our being notified, the Trustee may, in its discretion, sell any defaulted Bonds and will not be liable for any depreciation or loss incurred thereby. Except in the limited instance in which the Trust acquires Replacement Bonds as described in "The First Trust Combined Series," the Trust may not acquire any bonds or other property other than the Bonds. The Trustee, on behalf of the Trust, will reject any offer for new or exchanged bonds or property in exchange for a Bond, except that we may instruct the Trustee to accept such an offer or to take any other action with respect thereto as we may deem proper if the issuer is in default Page 21 with respect to such Bonds or in our written opinion the issuer will likely default in respect to such Bonds in the foreseeable future. Any obligations received in exchange or substitution will be held by the Trustee subject to the terms and conditions in the Indenture to the same extent as Bonds originally deposited in the Trust. We may get advice from the Portfolio Supervisor before reaching a decision regarding the receipt of new or exchange securities or property. The Trustee may retain and pay us or an affiliate of ours to act as agent for the Trust to facilitate selling Bonds, exchanged bonds or property from the Trust. If we or our affiliate act in this capacity, we will be held subject to the restrictions under the Investment Company Act of 1940, as amended. The Trustee may sell Bonds designated by us, or, absent our direction, at its own discretion, in order to meet redemption requests or pay expenses. We will maintain a list with the Trustee of which Bonds should be sold. We may consider sales of units of unit investment trusts which we sponsor in making recommendations to the Trustee on the selection of broker/dealers to execute the Trust's portfolio transactions, or when acting as agent for the Trust in acquiring or selling Bonds on behalf of the Trust. Amending or Terminating the Indenture Amendments. The Indenture may be amended by us and the Trustee without your consent: - - To cure ambiguities; - - To correct or supplement any defective or inconsistent provision; - - To make any amendment required by any governmental agency; or - - To make other changes determined not to be materially adverse to your best interests (as determined by us and the Trustee). Termination. As provided by the Indenture, the Trust will terminate on the Mandatory Termination Date. The Trust may be terminated prior to the Mandatory Termination Date: - - Upon the consent of 100% of the Unit holders; - - If the value of the Bonds owned by the Trust as shown by any evaluation is less than 20% of the aggregate principal amount of Bonds deposited in the Trust during the initial offering period ("Discretionary Liquidation Amount"); or - - In the event that Units of the Trust not yet sold aggregating more than 60% of the Units of such Trust are tendered for redemption by underwriters, including the Sponsor. Prior to termination, the Trustee will send written notice to all registered account holders which will specify how you should tender your certificates, if any, to the Trustee. If the Trust is terminated due to this last reason, we will refund your entire sales charge. 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 Bonds 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 Bonds. Because the Trustee must sell the Bonds within a relatively short period of time, the sale of Bonds 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 Bonds, along with your interest in the Interest and Principal Accounts of the Trust, within a reasonable time after the Trust is terminated. Regardless of the distribution involved, the Trustee will deduct from the Trust any accrued costs, expenses, advances or indemnities provided for by the Indenture, including estimated compensation of the Trustee and costs of liquidation and any amounts required as a reserve to pay any taxes or other governmental charges. Description of Bond Ratings* * As published by the rating companies. Standard & Poor's. A brief description of the applicable Standard & Poor's rating symbols and their meanings follows: A Standard & Poor's corporate or municipal bond rating is a current assessment of the creditworthiness of an obligor with respect to a specific debt obligation. This assessment may take into consideration obligors such as guarantors, insurers, or lessees. The bond rating is not a recommendation to purchase, sell, or hold a security, inasmuch as it does not comment as to market price or suitability for a particular investor. The ratings are based on current information furnished by the issuer or obtained by Standard & Poor's from other sources it considers reliable. Standard & Poor's does not perform an audit in connection with any rating and may, on occasion, rely on unaudited financial information. The ratings may be changed, suspended or withdrawn as a Page 22 result of changes in, or unavailability of, such information, or for other circumstances. The ratings are based, in varying degrees, on the following considerations: I. Likelihood of default-capacity and willingness of the obligor as to the timely payment of interest and repayment of principal in accordance with the terms of the obligation; II. Nature of and provisions of the obligation; III. Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization or other arrangements under the laws of bankruptcy and other laws affecting creditors' rights. AAA - Bonds rated AAA have the highest rating assigned by Standard & Poor's to a debt obligation. Capacity to pay interest and repay principal is extremely strong. AA - Bonds rated AA have a very strong capacity to pay interest and repay principal and differ from the highest rated issues only in small degree. A - Bonds rated A have a strong capacity to pay interest and repay principal although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than bonds in higher rated categories. BBB - Bonds rated BBB are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for bonds in this category than for bonds in higher rated categories. BB, B, CCC, CC - Debt rated BB, B, CCC and CC is regarded, on balance, as predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and CC the highest degree of speculation. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposure to adverse conditions. Plus (+) or Minus (-): The ratings from "AA" to "BBB" may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories. Provisional Ratings: The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the bonds being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, while addressing credit quality subsequent to completion of the project, makes no comment on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his or her own judgment with respect to such likelihood and risk. Credit Watch: Credit Watch highlights potential changes in ratings of bonds and other fixed income securities. It focuses on events and trends which place companies and government units under special surveillance by S&P's 180-member analytical staff. These may include mergers, voter referendums, actions by regulatory authorities, or developments gleaned from analytical reviews. Unless otherwise noted, a rating decision will be made within 90 days. Issues appear on Credit Watch where an event, situation, or deviation from trends occurred and needs to be evaluated as to its impact on credit ratings. A listing, however, does not mean a rating change is inevitable. Since S&P continuously monitors all of its ratings, Credit Watch is not intended to include all issues under review. Thus, rating changes will occur without issues appearing on Credit Watch. Moody's. A brief description of the applicable Moody's rating symbols and their meanings follows: Aaa - Bonds which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge." Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues. Their safety is so absolute that with the occasional exception of oversupply in a few specific instances, characteristically, their market value is affected solely by money market fluctuations. Aa - Bonds which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long term risks appear somewhat larger than in Aaa securities. Their market value is virtually immune to all but money market influences, with the occasional exception of oversupply in a few specific instances. A - Bonds which are rated A possess many favorable investment attributes and are to be considered as upper medium grade obligations. Factors Page 23 giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment sometime in the future. The market value of A-rated bonds may be influenced to some degree by economic performance during a sustained period of depressed business conditions, but, during periods of normalcy, A-rated bonds frequently move in parallel with Aaa and Aa obligations, with the occasional exception of oversupply in a few specific instances. A 1 and Baa 1 - Bonds which are rated A 1 and Baa 1 offer the maximum in security within their quality group, can be bought for possible upgrading in quality, and additionally, afford the investor an opportunity to gauge more precisely the relative attractiveness of offerings in the market place. Baa - Bonds which are rated Baa are considered as medium grade obligations; i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well. The market value of Baa-rated bonds is more sensitive to changes in economic circumstances, and aside from occasional speculative factors applying to some bonds of this class, Baa market valuations will move in parallel with Aaa, Aa, and A obligations during periods of economic normalcy, except in instances of oversupply. Ba - Bonds which are rated Ba are judged to have speculative elements; their future cannot be considered as well assured. Often the protection of interest and principal payments may be very moderate and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class. B - Bonds which are rated B generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small. Moody's bond rating symbols may contain numerical modifiers of a generic rating classification. The modifier 1 indicates that the bond ranks at the high end of its category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category. Con.(- - -) - Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operation experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting condition attaches. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition. Information on the Sponsor, Trustee and Evaluator The Sponsor.

The Trust will invest most of its net assets in securities issued by or on behalf of (or in certificates of participation in lease-purchase obligations of) the State of Colorado. The Trust is therefore susceptible to general or particular economic, political or regulatory factors that may affect issuers of Colorado obligations. The following information constitutes only a brief summary of some of the many complex factors that may have an effect. The information does not apply to "conduit" obligations on which the public issuer itself has no financial responsibility. This information is derived from official statements of certain National issuers published in connection with their issuance of securities and from other publicly available information, and is believed to be accurate. No independent verification has been made of any of the following information. Generally, creditworthiness of Colorado obligations of issuers is unrelated to that of obligations of the state itself, and the state has no responsibility to make payments on those local obligations. There may be specific factors that at particular times apply in connection with investment in particular Colorado obligations or in those obligations of particular Colorado issuers. However, the information below is intended only as a general summary, and is not intended as a discussion of any specific factors that may affect any particular obligation or issuer. The timely payment of principal of and interest on Colorado obligations has been guaranteed by bond insurance purchased by the issuers or other parties. Colorado's Economic Outlook. According to the September 2001 Colorado Economic Perspective ("September 2001 Forecast"), published by the Governor's Office of State Planning and Budgeting, through the first half of 2001, Colorado's economy appeared to be doing much better than the national economy and, despite numerous layoff announcements and slower retail sales growth, continues to perform better than many other states. However, the forecast for Colorado for the next six years anticipates much slower economic growth than the state has experienced in the past decade. Page 1 The September 2001 Forecast anticipates nonfarm employment will grow to 2.8% in 2001 and then slow to 2.4%. Thereafter, nonfarm employment growth will average 2.7% per year. Unemployment is expected to average only 3.1% in 2001 but then steadily increase to 3.7% by 2006. Personal income in Colorado is expected to increase 8.2% in 2001 due to increasing wages and salaries as well as the number of jobs available. Thereafter, growth in personal income will slow to 5.6% in 2002 as nonfarm employment growth slows. Colorado's construction sector is integral to the state's economic growth. In the mid-to-late 1990s, in response to the many new people and firms locating in Colorado, both residential and nonresidential construction boomed. The construction industry was also a growing employer for the state, employing as many as 162,000 workers. The September 2001 Forecast anticipates slowing in the construction industry. Through July 2001, the residential home market still grew significantly, but the number of homes on the market has since increased and prices are beginning to stabilize. Moreover, the value of nonresidential construction (excluding nonbuilding projects like roads) is relatively flat for the year and the vacancy rate in the office market is rising. Overall, there are signs of excess beginning to be seen in both the residential and nonresidential markets. The economic impact of the September 11 terrorist attacks on the World Trade Center and Pentagon is unclear. One impact of the attacks, however, is the detrimental effect on state budgets. The recent volatility in the stock markets and consumer spending will likely make things worse for states attempting to maintain balanced budgets. The decline in travel and tourism may also have serious implications for tax revenues in states such as Colorado. The State may be impacted more than others in the short term as the winter months are relatively busy tourist periods. Revenues and Expenditures. The State Constitution requires that expenditures for any fiscal year not exceed revenues for such fiscal year. By statute, the amount of General Fund revenues available for appropriation is based upon revenue estimates which, together with other available resources, must exceed annual appropriations by the amount of the unappropriated reserve (the "Unappropriated Reserve"). For fiscal years 1994 and thereafter, the Unappropriated Reserve requirement is set at 4%. In addition to the Unappropriated Reserve, a constitutional amendment approved by Colorado voters in 1992 requires the State and local government to reserve a certain percentage of its fiscal year spending (excluding bonded debt service) for emergency use (the "Emergency Reserve"). The minimum Emergency Reserve is set at 3% for 1995 and later years. For fiscal year 1992 and thereafter, General Fund appropriations are also limited by statute to an amount equal to the cost of performing certain required reappraisals of taxable property plus an amount equal to the lesser of (i) 5% of Colorado personal income or (ii) 106% of the total General Fund appropriations for the previous fiscal year. This restriction does not apply to any General Fund appropriations which are required as a result of a new federal law, a final state or federal court order or moneys derived from the increase in the rate or amount of any tax or fee approved by a majority of the registered electors of the State voting at any general election. In addition, the statutory limit on the level of General Fund appropriations may be exceeded for a given fiscal year upon the declaration of a State fiscal emergency by the State General Assembly. On November 3, 1992, voters in Colorado approved a constitutional amendment (the "Amendment") which, in general, became effective December 31, 1992, and restricts the ability of the State and local governments to increase revenues and impose taxes. The Amendment applies to the State and all local governments, including home rule entities ("Districts"). Enterprises, defined as government-owned businesses authorized to issue revenue bonds and receiving under 10% of annual revenue in grants from all Colorado state and local governments combined, are excluded from the provisions of the Amendment. The provisions of the Amendment are unclear and have required judicial interpretation. Among other provisions, beginning November 4, 1992, the Amendment requires voter approval prior to tax increases, creation of debt, or mill levy or valuation for assessment ratio increases. The Amendment also limits increases in government spending and property tax revenues to specified percentages. The Amendment requires that District property tax revenues yield no more than the prior year's revenues adjusted for inflation, voter approved changes and (except with regard to school districts) local growth in property values according to a formula set forth in the Amendment. School districts are allowed to adjust tax levies for changes in student enrollment. Pursuant to the Amendment, local government spending is to be limited by the same formula as the limitation for property tax revenues. The basis for spending and revenue limits for each fiscal year is the prior fiscal year's spending and property taxes collected in the prior calendar year. Debt service changes, reductions and voter-approved revenue changes are excluded from the calculation bases. The Amendment also prohibits new or increased real property transfer tax rates, new state real property taxes and local district income taxes. There is also a statutory restriction on the amount of annual increases in taxes that the various taxing jurisdictions in Colorado can levy without electoral approval. This restriction does not apply to taxes levied to pay general obligation debt. Litigation concerning several issues relating to the Amendment was filed Page 2 in the Colorado courts. The litigation dealt with three principal issues: (i) whether Districts can increase mill levies to pay debt service on general obligation bonds without obtaining voter approval; (ii) whether a multi-year lease purchase agreement subject to annual appropriations is an obligation which requires voter approval prior to execution of the agreement; and (iii) what constitutes an "enterprise" which is excluded from the provisions of the Amendment. In September 1994, the Colorado Supreme Court held that Districts can increase mill levies to pay debt service on general obligation bonds issued after the effective date of the Amendment; in June, 1995, the Colorado Supreme Court validated mill levy increases to pay general obligation bonds issued prior to the Amendment. In late 1994, the Colorado Court of Appeals held that multi-year lease-purchase agreements subject to annual appropriation do not require voter approval. The time to file an appeal in that case has expired. Finally, in May, 1995, the Colorado Supreme Court ruled that entities with the power to levy taxes may not themselves be "enterprises" for purposes of the Amendment; however, the Court did not address the issue of how valid enterprises may be created. Litigation in the "enterprise" arena may be filed in the future to clarify these issues. The Taxpayer's Bill of Rights ("TABOR"), Article X, Section 20 of the Colorado State Constitution, limits the state's revenue growth to the sum of inflation plus population growth in the previous calendar year. The state first exceed the TABOR limit in FY 1996-97. Since then, the amount of the TABOR surplus surged, reaching $927.2 million in FY 2000- 01. A healthy economy and the prolonged national economic expansion of the 1990s generated strong growth in General Fund revenues. The robust revenue growth coupled with the low TABOR limit, led to large TABOR surpluses. The September 2001 Forecast projects that the state will not continue to enjoy the large TABOR surpluses of recent years. Indeed, the TABOR surplus is expected to range from only $93.2 million to $142.6 million in the next six years. There are several reasons for the decline in TABOR surplus. First, two measures passed by Colorado voters in the November 2000 election lower surplus revenues: Amendment 23, which provides increased public school funding, exempted roughly $330 million from the TABOR surplus; and Referendum A, which provides property tax relief for senior citizens, lowers the amount of the surplus by $44 million. Second, since 2000 was a federal census year, the state now has an accurate count of its population reflecting a higher population growth thus increasing the TABOR limit. Third, Colorado's economy is expected to grow at slower rates resulting in lower General Fund revenue growth. Fourth, tax relief packages enacted in the last three years allow Coloradoans to keep more of their income. Finally, the 2001 federal tax relief will lower Colorado revenues. According to September 2001 Forecast, General Fund revenues increased 6.3% in FY 2000-01, much lower than FY 1999-00's 8.8% pace. General Fund revenues are forecast to increase 1.8% in FY 2001-02 and 6.7% in FY 2002- 2003. The monies in excess of the General Fund reserve are typically used for capital expenditures and tax relief. In FY 2001-2002, the fiscal year- end General Fund reserve is forecast to be $224.9 million, which is exactly equal to the four percent statutory requirement. The need to provide funds to complete capital projects begun in previous years, the passage of Amendment 23, the large sales tax over-refund, and a decrease in projected revenues lowered the FY 2001-02 reserve level. The September 2001 Forecast predicts that the total amount of cash fund revenues in FY 2001-02 will be approximately $2,366 million. Cash fund revenues are forecast to increase 2.1% in FY 2001-02 and to increase 7.6% in FY 2002-03. From FY 2001-02 through FY 2006-07, cash fund revenues will increase at a compound annual average rate of 5.3%. It is anticipated that by FY 2006-07, the fiscal year-end General Fund reserve will be $2,196.3 million. Debt Management. Under its constitution, the State of Colorado is not permitted to issue general obligation bonds secured by the full faith and credit of the State. However, certain agencies and instrumentalities of the State are authorized to issue bonds secured by revenues from specific projects and activities. The State enters into certain lease transactions which are subject to annual renewal at the option of the State. In addition, the State is authorized to issue short-term revenue anticipation notes. Local governmental units in the State are also authorized to incur indebtedness. The major source of financing for such local government indebtedness is an ad valorem property tax. In addition, in order to finance public projects, local governments in the State can issue revenue bonds payable from the revenues of a utility or enterprise or from the proceeds of an excise tax, or assessment bonds payable from special assessments. Colorado local governments can also finance public projects through leases which are subject to annual appropriation at the option of the local government. Local governments in Colorado also issue tax anticipation notes. The Amendment requires prior voter approval for the creation of any multiple fiscal year debt or other financial obligation whatsoever, except for refundings at a lower rate or obligations of an enterprise. The Trust is susceptible to political, economic or regulatory factors affecting issuers of Colorado municipal obligations (the "Colorado Page 3 Municipal Obligations"). These include the possible adverse effects of certain Colorado constitutional amendments, legislative measures, voter initiatives and other matters. The information provided is only a brief summary of the complex factors affecting the financial situation in Colorado and is derived from sources that are generally available to investors and are believed to be accurate. No independent verification has been made of the accuracy or completeness of any of the preceding information. It is based in part on information obtained from various State and local agencies in Colorado or contained in Official Statements for various Colorado Municipal Obligations. The foregoing information constitutes only a brief summary of some of the general factors which may impact certain issuers of Bonds and does not purport to be a complete or exhaustive description of all adverse conditions to which the issuers of Bonds held by the Trust are subject. Additionally, many factors including national economic, social and environmental policies and conditions, which are not within the control of the issuers of the Bonds, could affect or could have an adverse impact on the financial condition of the issuers. The Sponsor is unable to predict whether or to what extent such factors or other factors may affect the issuers of the Bonds, the market value or marketability of the Bonds or the ability of the respective issuers of the Bonds acquired by the Trust to pay interest on or principal of the Bonds. Federal Tax-Free Income The following table shows the approximate marginal taxable yields for individuals that are equivalent to tax-exempt yields under combined federal and state taxes, using published 2002 marginal federal tax rates and marginal state tax rates currently available and scheduled to be in effect. For cases in which more than one state bracket falls within a federal bracket, the higher state bracket is combined with the federal bracket. The combined state and federal tax rates shown reflect the fact that state tax payments are currently deductible for Federal tax purposes. The table illustrates what you would have to earn on taxable investments to equal the tax-exempt yield for your income tax bracket. The taxable equivalent yields may be somewhat higher than the equivalent yields indicated in the following table for those individuals who have adjusted gross incomes in excess of $137,300. The table does not reflect the effect of the limitations on itemized deductions and the deduction for personal exemptions. They were designed to phase out certain benefits of these deductions for higher income taxpayers. These limitations, in effect, raise the maximum marginal federal tax rate to approximately 43.5% for taxpayers filing a joint return and entitled to four personal exemptions and to approximately 39.8% for taxpayers filing a single return entitled to only one personal exemption. These limitations are subject to certain maximums, which depend on the number of exemptions claimed and the total amount of the taxpayer's itemized deductions. For example, the limitation on itemized deductions will not cause a taxpayer to lose more than 80% of his allowable itemized deductions, with certain exceptions.

Other bonds in the funds may be revenue bonds payable from the income of a specific project or authority and are not supported by the issuer's power to levy taxes. General obligation bonds are secured by the issuer's pledge of its faith, credit and taxing power for the payment of principal and interest. Revenue bonds, on the other hand, are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source. There are, of course, variations in the security of the different bonds in the funds, both within a particular classification and between classifications, depending on numerous factors. A description of certain types of revenue bonds follows. Healthcare Revenue Bonds. Certain of the bonds may be healthcare revenue Page 4 bonds. Ratings of bonds issued for healthcare facilities are sometimes based on feasibility studies that contain projections of occupancy levels, revenues and expenses. A facility's gross receipts and net income available for debt service may be affected by future events and conditions including among other things, demand for services, the ability of the facility to provide the services required, physicians' confidence in the facility, management capabilities, competition with other hospitals, efforts by insurers and governmental agencies to limit rates, legislation establishing state rate-setting agencies, expenses, government regulation, the cost and possible unavailability of malpractice insurance and the termination or restriction of governmental financial assistance, including that associated with Medicare, Medicaid and other similar third party payor programs. Pursuant to recent Federal legislation, Medicare reimbursements are currently calculated on a prospective basis utilizing a single nationwide schedule of rates. Prior to such legislation Medicare reimbursements were based on the actual costs incurred by the health facility. The current legislation may adversely affect reimbursements to hospitals and other facilities for services provided under the Medicare program. Single Family Mortgage Revenue Bonds. Certain of the bonds may be single family mortgage revenue bonds, which are issued for the purpose of acquiring from originating financial institutions notes secured by mortgages on residences located within the issuer's boundaries and owned by persons of low or moderate income. Mortgage loans are generally partially or completely prepaid prior to their final maturities as a result of events such as sale of the mortgaged premises, default, condemnation or casualty loss. Because these bonds are subject to extraordinary mandatory redemption in whole or in part from such prepayments of mortgage loans, a substantial portion of such bonds will probably be redeemed prior to their scheduled maturities or even prior to their ordinary call dates. The redemption price of such issues may be more or less than the offering price of such bonds. Extraordinary mandatory redemption without premium could also result from the failure of the originating financial institutions to make mortgage loans in sufficient amounts within a specified time period or, in some cases, from the sale by the bond issuer of the mortgage loans. Failure of the originating financial institutions to make mortgage loans would be due principally to the interest rates on mortgage loans funded from other sources becoming competitive with the interest rates on the mortgage loans funded with the proceeds of the single family mortgage revenue bonds. Additionally, unusually high rates of default on the underlying mortgage loans may reduce revenues available for the payment of principal of or interest on such mortgage revenue bonds. Single family mortgage revenue bonds issued after December 31, 1980 were issued under Section 103A of the Internal Revenue Code, which Section contains certain ongoing requirements relating to the use of the proceeds of such bonds in order for the interest on such bonds to retain its tax-exempt status. In each case, the issuer of the bonds has covenanted to comply with applicable ongoing requirements and bond counsel to such issuer has issued an opinion that the interest on the bonds is exempt from Federal income tax under existing laws and regulations. There can be no assurances that the ongoing requirements will be met. The failure to meet these requirements could cause the interest on the bonds to become taxable, possibly retroactively from the date of issuance. Multi-Family Mortgage Revenue Bonds. Certain of the bonds may be obligations of issuers whose revenues are primarily derived from mortgage loans to housing projects for low to moderate income families. The ability of such issuers to make debt service payments will be affected by events and conditions affecting financed projects, including, among other things, the achievement and maintenance of sufficient occupancy levels and adequate rental income, increases in taxes, employment and income conditions prevailing in local labor markets, utility costs and other operating expenses, the managerial ability of project managers, changes in laws and governmental regulations, the appropriation of subsidies and social and economic trends affecting the localities in which the projects are located. The occupancy of housing projects may be adversely affected by high rent levels and income limitations imposed under Federal and state programs. Like single family mortgage revenue bonds, multi-family mortgage revenue bonds are subject to redemption and call features, including extraordinary mandatory redemption features, upon prepayment, sale or non-origination of mortgage loans as well as upon the occurrence of other events. Certain issuers of single or multi-family housing bonds have considered various ways to redeem bonds they have issued prior to the stated first redemption dates for such bonds. In one situation the New York City Housing Development Corporation, in reliance on its interpretation of certain language in the indenture under which one of its bond issues was created, redeemed all of such issue at par in spite of the fact that such indenture provided that the first optional redemption was to include a premium over par and could not occur prior to 1992. Water and Sewerage Revenue Bonds. Certain of the bonds may be obligations of issuers whose revenues are derived from the sale of water and/or sewerage services. Water and sewerage bonds are generally payable from user fees. Problems faced by such issuers include the ability to obtain timely and adequate rate increases, population decline resulting in decreased user fees, the difficulty of financing large construction Page 5 programs, the limitations on operations and increased costs and delays attributable to environmental considerations, the increasing difficulty of obtaining or discovering new supplies of fresh water, the effect of conservation programs and the impact of "no-growth" zoning ordinances. All of such issuers have been experiencing certain of these problems in varying degrees. Electric Utility Revenue Bonds. Certain of the bonds may be obligations of issuers whose revenues are primarily derived from the sale of electric energy. Utilities are generally subject to extensive regulation by state utility commissions which, among other things, establish the rates which may be charged and the appropriate rate of return on an approved asset base. The problems faced by such issuers include the difficulty in obtaining approval for timely and adequate rate increases from the governing public utility commission, the difficulty in financing large construction programs, the limitations on operations and increased costs and delays attributable to environmental considerations, increased competition, recent reductions in estimates of future demand for electricity in certain areas of the country, the difficulty of the capital market in absorbing utility debt, the difficulty in obtaining fuel at reasonable prices and the effect of energy conservation. All of such issuers have been experiencing certain of these problems in varying degrees. In addition, Federal, state and municipal governmental authorities may from time to time review existing and impose additional regulations governing the licensing, construction and operation of nuclear power plants, which may adversely affect the ability of the issuers of such bonds to make payments of principal and/or interest on such bonds. Lease Obligation Revenue Bonds. Certain of the bonds may be lease obligations issued for the most part by governmental authorities that have no taxing power or other means of directly raising revenues. Rather, the governmental authorities are financing vehicles created solely for the construction of buildings (schools, administrative offices, convention centers and prisons, for example) or the purchase of equipment (police cars and computer systems, for example) that will be used by a state or local government (the "lessee"). Thus, these obligations are subject to the ability and willingness of the lessee government to meet its lease rental payments which include debt service on the obligations. Lease obligations are subject, in almost all cases, to the annual appropriation risk, i.e., the lessee government is not legally obligated to budget and appropriate for the rental payments beyond the current fiscal year. These obligations are also subject to construction and abatement risk in many states-rental obligations cease in the event that delays in building, damage, destruction or condemnation of the project prevents its use by the lessee. In these cases, insurance provisions designed to alleviate this risk become important credit factors. In the event of default by the lessee government, there may be significant legal and/or practical difficulties involved in the re-letting or sale of the project. Some of these issues, particularly those for equipment purchase, contain the so-called "substitution safeguard," which bars the lessee government, in the event it defaults on its rental payments, from the purchase or use of similar equipment for a certain period of time. This safeguard is designed to insure that the lessee government will appropriate, even though it is not legally obligated to do so, but its legality remains untested in most, if not all, states. Industrial Revenue Bonds. Certain of the bonds may be industrial revenue bonds ("IRBs"), including pollution control revenue bonds, which are tax- exempt securities issued by states, municipalities, public authorities or similar entities to finance the cost of acquiring, constructing or improving various industrial projects. These projects are usually operated by corporate entities. Issuers are obligated only to pay amounts due on the IRBs to the extent that funds are available from the unexpended proceeds of the IRBs or receipts or revenues of the issuer under an arrangement between the issuer and the corporate operator of a project. The arrangement may be in the form of a lease, installment sale agreement, conditional sale agreement or loan agreement, but in each case the payments to the issuer are designed to be sufficient to meet the payments of amounts due on the IRBs. Regardless of the structure, payment of IRBs is solely dependent upon the creditworthiness of the corporate operator of the project or corporate guarantor. Corporate operators or guarantors may be affected by many factors which may have an adverse impact on the credit quality of the particular company or industry. These include cyclicality of revenues and earnings, regulatory and environmental restrictions, litigation resulting from accidents or environmentally-caused illnesses, extensive competition and financial deterioration resulting from a complete restructuring pursuant to a leveraged buy-out, takeover or otherwise. Such a restructuring may result in the operator of a project becoming highly leveraged which may impact on such operator's creditworthiness, which in turn would have an adverse impact on the rating and/or market value of such bonds. Further, the possibility of such a restructuring may have an adverse impact on the market for and consequently the value of such bonds, even though no actual takeover or other action is ever contemplated or affected. The IRBs in a fund may be subject to special or extraordinary redemption provisions which may provide for redemption at par or, with respect to original issue discount bonds, at issue price plus the amount of original issue discount accreted to the redemption date plus, if applicable, a premium. The Sponsor cannot predict the causes or likelihood of the redemption of IRBs or other bonds in the funds prior to the stated maturity of such bonds. Transportation Facility Revenue Bonds. Certain of the bonds may be obligations which are payable from and secured by revenues derived from Page 6 the ownership and operation of facilities such as airports, bridges, turnpikes, port authorities, convention centers and arenas. The major portion of an airport's gross operating income is generally derived from fees received from signatory airlines pursuant to use agreements which consist of annual payments for leases, occupancy of certain terminal space and service fees. Airport operating income may therefore be affected by the ability of the airlines to meet their obligations under the use agreements. The air transport industry is experiencing significant variations in earnings and traffic, due to increased competition, excess capacity, increased costs, deregulation, traffic constraints and other factors, and several airlines are experiencing severe financial difficulties. The Sponsor cannot predict what effect these industry conditions may have on airport revenues which are dependent for payment on the financial condition of the airlines and their usage of the particular airport facility. Similarly, payment on bonds related to other facilities is dependent on revenues from the projects, such as user fees from ports, tolls on turnpikes and bridges and rents from buildings. Therefore, payment may be adversely affected by reduction in revenues due to such factors as increased cost of maintenance, decreased use of a facility, lower cost of alternative modes of transportation, scarcity of fuel and reduction or loss of rents. Educational Obligation Revenue Bonds. Certain of the bonds may be obligations of issuers which are, or which govern the operation of, schools, colleges and universities and whose revenues are derived mainly from ad valorem taxes, or for higher education systems, from tuition, dormitory revenues, grants and endowments. General problems relating to school bonds include litigation contesting the state constitutionality of financing public education in part from ad valorem taxes, thereby creating a disparity in educational funds available to schools in wealthy areas and schools in poor areas. Litigation or legislation on this issue may affect the sources of funds available for the payment of school bonds in the funds. General problems relating to college and university obligations would include the prospect of a declining percentage of the population consisting of "college" age individuals, possible inability to raise tuitions and fees sufficiently to cover increased operating costs, the uncertainty of continued receipt of Federal grants and state funding and new government legislation or regulations which may adversely affect the revenues or costs of such issuers. All of such issuers have been experiencing certain of these problems in varying degrees. Resource Recovery Facility Revenue Bonds. Certain of the bonds may be obligations which are payable from and secured by revenues derived from the operation of resource recovery facilities. Resource recovery facilities are designed to process solid waste, generate steam and convert steam to electricity. Resource recovery bonds may be subject to extraordinary optional redemption at par upon the occurrence of certain circumstances, including but not limited to: destruction or condemnation of a project; contracts relating to a project becoming void, unenforceable or impossible to perform; changes in the economic availability of raw materials, operating supplies or facilities necessary for the operation of a project or technological or other unavoidable changes adversely affecting the operation of a project; administrative or judicial actions which render contracts relating to the projects void, unenforceable or impossible to perform; or impose unreasonable burdens or excessive liabilities. The Sponsor cannot predict the causes or likelihood of the redemption of resource recovery bonds in the funds prior to the stated maturity of the Bonds. Discount Bonds. Certain of the bonds may have been acquired at a market discount from par value at maturity. The coupon interest rates on the discount bonds at the time they were purchased and deposited in the funds were lower than the current market interest rates for newly issued bonds of comparable rating and type. If such interest rates for newly issued comparable bonds increase, the market discount of previously issued bonds will become greater, and if such interest rates for newly issued comparable bonds decline, the market discount of previously issued bonds will be reduced, other things being equal. Investors should also note that the value of bonds purchased at a market discount will increase in value faster than bonds purchased at a market premium if interest rates decrease. Conversely, if interest rates increase, the value of bonds purchased at a market discount will decrease faster than bonds purchased at a market premium. In addition, if interest rates rise, the prepayment risk of higher yielding, premium bonds and the prepayment benefit for lower yielding, discount bonds will be reduced. A discount bond held to maturity will have a larger portion of its total return in the form of taxable income and capital gain and less in the form of tax-exempt interest income than a comparable bond newly issued at current market rates. Market discount attributable to interest changes does not indicate a lack of market confidence in the issue. Neither the Sponsor nor the Trustee shall be liable in any way for any default, failure or defect in any of the bonds. Original Issue Discount Bonds. Certain of the bonds may be original issue discount bonds. Under current law, the original issue discount, which is the difference between the stated redemption price at maturity and the issue price of the bonds, is deemed to accrue on a daily basis and the accrued portion is treated as tax-exempt interest income for Federal income tax purposes. On sale or redemption, any gain realized that is in excess of the earned portion of original issue discount will be taxable as capital gain unless the gain is attributable to market discount in which case the accretion of market discount is taxable as ordinary income. The current value of an original issue discount bond Page 7 reflects the present value of its stated redemption price at maturity. The market value tends to increase in greater increments as the bonds approach maturity. Zero Coupon Bonds. Certain of the original issue discount bonds may be zero coupon bonds (including bonds known as multiplier bonds, money multiplier bonds, capital appreciation bonds, capital accumulator bonds, compound interest bonds and money discount maturity payment bonds). Zero coupon bonds do not provide for the payment of any current interest and generally provide for payment at maturity at face value unless sooner sold or redeemed. Zero coupon bonds may be subject to more price volatility than conventional bonds. While some types of zero coupon bonds, such as multipliers and capital appreciation bonds, define par as the initial offering price rather than the maturity value, they share the basic zero coupon bond features of (1) not paying interest on a semi- annual basis and (2) providing for the reinvestment of the bond's semi- annual earnings at the bond's stated yield to maturity. While zero coupon bonds are frequently marketed on the basis that their fixed rate of return minimizes reinvestment risk, this benefit can be negated in large part by weak call protection, i.e., a bond's provision for redemption at only a modest premium over the accreted value of the bond. Premium Bonds. Certain of the bonds may have been acquired at a market premium from par value at maturity. The coupon interest rates on the premium bonds at the time they were purchased by the fund were higher than the current market interest rates for newly issued bonds of comparable rating and type. If such interest rates for newly issued and otherwise comparable bonds decrease, the market premium of previously issued bonds will be increased, and if such interest rates for newly issued comparable bonds increase, the market premium of previously issued bonds will be reduced, other things being equal. The current returns of bonds trading at a market premium are initially higher than the current returns of comparable bonds of a similar type issued at currently prevailing interest rates because premium bonds tend to decrease in market value as they approach maturity when the face amount becomes payable. Because part of the purchase price is thus returned not at maturity but through current income payments, early redemption of a premium bond at par or early prepayments of principal will result in a reduction in yield. Redemption pursuant to call provisions generally will, and redemption pursuant to sinking fund provisions may, occur at times when the redeemed bonds have an offering side valuation which represents a premium over par or for original issue discount bonds a premium over the accreted value.
