              THE TRUST  The Trust consists of a diversified portfolio of
    $1,505,000 principal amount of long-term Debt Obligations which, on the
    Date of Deposit, were rated "A" or better by Standard & Poor's
    Corporation, Moody's Investors Service, Inc. or Fitch Investors Service,
    Inc. or possessed, in the opinion of the Sponsor, similar credit
    characteristics.  For a discussion of the significance of such ratings,
    see "Description of Bond Ratings" in Part B.  The principal objectives of
    the Trust are the return of a high level of current income and the
    preservation of capital.  The Sponsor, under certain circumstances
    consistent with the Trust's objectives, may direct the Trustees to sell
    certain of the Debt Obligations and reinvest the proceeds in substitute
    Debt Obligations (see "Portfolio Supervision" in Part B).  The payment of
    interest and the preservation of capital are dependent upon the continuing
    ability of the issuers of the Debt Obligations to meet their obligations,
    and thus there can be no assurance that the Trust's investment objectives
    will be achieved.  Each Unit in the Trust represents a 1/3233rd undivided
    interest in the principal and net income of the Trust in the ratio of one
    Unit for each $1,000 principal amount of Debt Obligations deposited in the
    Trust.  (See "The Trust--Organization" in Part B of this Prospectus.)  The
    Units being offered hereby are issued and outstanding Units which have
    been purchased by the Sponsor in the secondary market.

              PUBLIC OFFERING PRICE  The Public Offering Price of each Unit is
    equal to the aggregate bid price of the Debt Obligations in the Trust
    divided by the number of Units outstanding, plus a sales charge of 4.5% of
    the Public Offering Price or 4.712% of the net amount invested in Debt
    Obligations per Unit.  In addition, accrued interest to the expected date
    of settlement is added to the Public Offering Price.  If Units had been
    purchased on the Evaluation Date, the Public Offering Price per Unit would
    have been $173.35 plus accrued interest of $19.26 under the monthly
    distribution plan and $19.61 under the semi-annual distribution plan for a
    total of $192.61 and $192.96, respectively.  The Public Offering Price per
    Unit can vary on a daily basis in accordance with fluctuations in the
    prices of the Debt Obligations.  (See "Public Offering" on page 11.)

              ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN.  The
    rate of return on an investment in Units of the Trust is measured in terms
    of "Estimated Current Return" and "Estimated Long Term Return".

              Estimated Long Term Return is calculated by:  (1) computing the
    yield to maturity or to an earlier call date (whichever results in a lower
    yield) for each Debt Obligation in the Trust's portfolio in accordance
    with accepted debt obligation practices, which practices take into account
    not only the interest payable on the Debt Obligation but also the
    amortization of premiums or accretion of discounts, if any;
    (2) calculating the average of the yields for the Debt Obligations in the
    Trust's portfolio by weighing each Debt Obligation's yield by the market
    value of the Debt Obligation and by the amount of time remaining to the
    date to which the Debt Obligation is priced (thus creating an average
    yield for the portfolio of the Trust); and (3) reducing the average yield
    for the portfolio of the Trust in order to reflect estimated fees and
    expenses of the Trust and the maximum sales charge paid by investors.  The
    resulting Estimated Long Term Return represents a measure of the return to
    investors earned over the estimated life of the Trust.  (For the Estimated
    Long Term Return to Certificateholders under the monthly, semi-annual and
    annual distribution plans, see "Summary of Essential Information".)

              Estimated Current Return is a measure of the Trust's cash flow. 
    Estimated Current Return is computed by dividing the Estimated Net Annual
    Interest Income per Unit by the Public Offering Price per Unit.  In
    contrast to the Estimated Long Term Return, the Estimated Current Return
    does not take into account the amortization of premium or accretion of
    discount, if any, on the Debt Obligations in the portfolio of the Trust. 
    Moreover, because interest rates on Debt Obligations purchased at a
    premium are generally higher than current interest rates on newly issued
    bonds of a similar type with comparable rating, the Estimated Current
    Return per Unit may be affected adversely if such Debt Obligations are
    redeemed prior to their maturity.  

              The Estimated Net Annual Interest Income per Unit of the Trust
    will vary with changes in the fees and expenses of the Trustee and the
    Evaluator applicable to the Trust and with the redemption, maturity, sale
    or other disposition of the Debt Obligations in the Trust.  The Public
    Offering Price will vary with changes in the bid prices of the Debt
    Obligations.  Therefore, there is no assurance that the present Estimated
    Current Return or Estimated Long Term Return will be realized in the
    future.  (For the Estimated Current Return to Certificateholders under the
    monthly, semi-annual and annual distribution plans, see "Summary of
    Essential Information".  See "Estimated Long Term Return and Estimated
    Current Return" in Part B of this Prospectus.)

              A schedule of cash flow projections is available from the
    Sponsor upon request. 
        

              DISTRIBUTIONS  Distributions of interest income, less expenses,
    will be made by the Trust either monthly or semi-annually depending upon
    the plan of distribution applicable to the Unit purchased.  A purchaser of
    a Unit will initially receive distributions in accordance with the plan
    selected by the prior owner and may thereafter change the plan as provided
    in "Interest and Principal Distributions" in Part B.  Distributions of
    principal, if any, will be made semi-annually on June 15 and December 15
    of each year.  For estimated monthly and semi-annual distributions, see
    "Summary of Essential Information".
       
              MARKET FOR UNITS  The Sponsor, although not obligated to do so,
    presently maintains and intends to continue to maintain a market for the
    Units at prices based upon the aggregate bid price of the Debt Obligations
    in the portfolio of the Trust.  The reoffer price is based on the
    aggregate bid price of the Bonds plus a sales charge of 4.5% (4.712% of
    the net amount invested) plus net accrued interest.  If such a market is
    not maintained, a Certificateholder will be able to redeem his Units with
    the Trustee at a price based upon the aggregate bid price of the Debt
    Obligations.  (See "Sponsor Repurchase" and "Public Offering--Offering
    Price" in Part B.)
        
              TOTAL REINVESTMENT PLAN  Certificateholders under the semi-
    annual plan of distribution have the opportunity to have their regular
    semi-annual interest distributions and principal distributions, if any,
    reinvested in available series of "A Corporate Trust."  (See "Total
    Reinvestment Plan" in Part B.  Residents of Texas see "Total Reinvestment
    Plan for Texas Residents" in Part B.)  The Plan is not designed to be a
    complete investment program.

    Description of Portfolio

          The portfolio of the Trust consists of 2 issues of Debt Obligations
    of 2 issuers.  Approximately 43.3% of the Debt Obligations are secured and
    approximately 56.7% are unsecured.  All of the unsecured Debt Obligations
    represent senior unsecured indebtedness.  One issue, representing
    approximately 43.4% of the aggregate principal amount of Debt Obligations
    is issued by an electric and gas utility.  None are securities of foreign
    issuers.  As of the Evaluation Date, $530,000 of the Debt Obligations are
    long-term corporate debt obligations.  The Sponsor has not participated as
    a sole underwriter, manager, co-manager, member of an underwriting
    syndicate or agent in private placements from which any of the Debt
    Obligations were acquired.  For an explanation of the significance of
    these factors, see "The Trust Portfolio" in Part B.  None of the Bonds
    have any equity or conversion features.

Independent Auditors' Report


The Sponsor, Trustee and Certificateholders
A Corporate Trust, Series 1:


We have audited the accompanying statement of net assets, including
the portfolio, of A Corporate Trust, Series 1 as of December 31,
1993, and the related statements of operations and changes in net
assets for each of the years in the three year period then ended.
These financial statements are the responsibility of the Trustee
(see note 2).  Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements.  Our procedures included
confirmation of securities owned as of December 31, 1993, by
correspondence with the Trustee.  An audit also includes assessing
the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of A
Corporate Trust, Series 1 as of December 31, 1993, and the results
of its operations and the changes in its net assets for each of the
years in the three year period then ended in conformity with
generally accepted accounting principles.

A CORPORATE TRUST, SERIES 1

Notes to Financial Statements

December 31, 1993, 1992 and 1991


(1)    Organization

A Corporate Trust, Series 1 (Trust) was organized on October 20, 1978
by Bear, Stearns & Co. Inc. (Sponsor) under the laws of the State of
New York by a Trust Indenture and Agreement, and is registered under
the Investment Company Act of 1940.

(2)    Summary of Significant Accounting Policies

The Bank of New York (Trustee) has custody of and responsibility for
the accounting records and financial statements of the Trust and is
responsible for establishing and maintaining a system of internal
control related thereto.

The Trustee is also responsible for all estimates of expenses and
accruals reflected in the Trust's financial statements.  The
accompanying financial statements have been adjusted to record the
unrealized appreciation (depreciation) of investments and to record
interest income and expenses on the accrual basis.

Investments are carried at market value which is determined by either
Standard & Poor's Corporation or Moody's Investors Service, Inc.
(Evaluator) as discussed in Footnotes to Portfolio.  The market value
of the investments is based upon the bid prices for the bonds at the
end of the year, except that the market value on the date of deposit
represents the cost to each state Trust based on the offering prices
for investments at that date.  The difference between cost and market
value is reflected as unrealized appreciation (depreciation) of
investments.  Securities transactions are recorded on the trade date.
Realized gains (losses) from securities transactions are determined
on the basis of average cost of the securities sold or redeemed.

(3)    Income Taxes

The Trust is not subject to Federal income taxes as provided for by
the Internal Revenue Code.


(4)    Trust Administration

The fees and expenses of the Trust are incurred and paid on the basis
set forth under "Trust Expenses and Charges" in Part B of this
Prospectus.

The Trust Indenture and Agreement provides for interest distributions
as often as monthly (depending upon the distribution plan elected by
the Certificateholders).

The Trust Indenture and Agreement further requires that principal
received from the disposition of bonds, other than those bonds sold
in connection with the redemption of units, be distributed to
Certificateholders.

See "Financial and Statistical Information" in Part A of this
Prospectus for the amounts of per unit distributions during the years
ended December 31, 1993, 1992 and 1991.

The Trust Indenture and Agreement also requires the Trust to redeem
units tendered. 183, 167 and 338 units were redeemed during the years
ended December 31, 1993, 1992 and 1991, respectively.

(5)    Net Assets

 At December 31, 1993, the net assets of the Trust represented the
 interest  of Certificateholders as follows:

   Original cost to Certificateholders                   $ 6,163,655
   Less initial gross underwriting commission               (277,380)

                                                           5,886,275

   Cost of securities sold or called                      (5,436,638)
   Net unrealized appreciation                                85,565
   Undistributed net investment income                        19,761
   Undistributed proceeds from bonds sold or called              160

            Total                                        $   555,123


The original cost to Certificateholders, less the initial gross
underwriting commission, represents the aggregate initial public
offering price net of the applicable sales charge on 6,000 units
of fractional undivided interest of the Trust as of the date of
deposit.

                                 Prospectus Part B
       
                              Dated:  April 29, 1994
        

                                     THE TRUST

    Organization

               "A Corporate Trust" (the "Trust") is a "unit investment trust"
    created under the laws of the Commonwealth of Massachusetts pursuant to a
    Trust Indenture and Agreement* (the "Trust Agreement"), dated the Date of
    Deposit, among Bear, Stearns & Co. Inc., as Sponsor, The Bank of New York,
    Wall Street Trust Division, as Trustee, and Interactive Data Services,
    Inc., as Evaluator. 

    *     References in this Prospectus to the Trust Agreement are qualified
          in their entirety by the Trust Indenture and Agreement which is
          incorporated herein by reference.


    <PAGE>

               On the Date of Deposit the Sponsor deposited with the Trustee
    long-term corporate and government debt obligations, including delivery
    statements relating to contracts for the purchase of certain such
    obligations (the "Debt Obligations") and cash or an irrevocable letter of
    credit issued by a major commercial bank in the amount required for such
    purchases.  Thereafter, the Trustee, in exchange for the Debt Obligations
    so deposited, delivered to the Sponsor the Certificates evidencing the
    ownership of all Units of the Trust. 

               Each "Unit" outstanding on the Evaluation Date represented an
    undivided interest or pro rata share in the principal and interest of the
    Trust in the ratio of one Unit for each $1,000 principal amount of Debt
    Obligations deposited in the Trust.  To the extent that any Units are
    redeemed by the Trustee, the fractional undivided interest or pro rata
    share in the Trust represented by each unredeemed Unit will increase,
    although the actual interest in the Trust represented by such fraction
    will remain unchanged.  Units will remain outstanding until redeemed upon
    tender to the Trustee by Certificateholders, which may include the
    Sponsor, or until the termination of the Trust Agreement. 

    Objectives

               The Trust offers investors the opportunity to participate in a
    portfolio of long-term taxable Debt Obligations with a greater
    diversification than they might be able to acquire themselves.  The
    principal objectives of the Trust are preservation of capital and a high
    level of interest income relative to prevailing interest rates on other
    similar investments on the Date of Deposit.  Investors should be aware
    that there is no assurance the Trust's objectives will be achieved as
    these objectives are dependent on the continuing ability of the issuers of
    the Debt Obligations to meet their interest and principal payment
    requirements, and on the market value of the Debt Obligations, which can
    be affected by fluctuations in interest rates and other factors. 

               Since disposition of Units prior to final liquidation of the
    Trust may result in an investor receiving less than the amount paid for
    such Units (see "Comparison of Public Offering Price and Redemption
    Price"), the purchase of a Unit should be looked upon as a long-term
    investment.  The Trust is not designed to be a complete investment
    program. 

    Portfolio

               All of the Debt Obligations in the Trust were rated "A" or
    better by Standard & Poor's Corporation or Moody's Investors Service, Inc.
    at the time originally deposited in the Trust.  For a list of the ratings
    of each Bond on the Evaluation Date, see "Portfolio" in Part A.

               For information regarding (i) the number of issues in the
    Trust, (ii) the range of fixed maturities of the Debt Obligations,
    (iii) the number of issues payable from the income of a specific project
    or authority and (iv) the number of issues constituting general
    obligations of a government entity, see "Information Regarding the Trust"
    and "Description of Portfolio" in Part A of this Prospectus. 

               When selecting Debt Obligations for the Trust, the following
    factors, among others, were considered by the Sponsor on the Date of
    Deposit:  (a) the quality of the Debt Obligations and whether such Debt
    Obligations were rated "A" or better by either Standard & Poor's
    Corporation, Moody's Investors Service, Inc., or Fitch Investors Service,
    Inc., or had, in the opinion of the Sponsor, similar credit
    characteristics, (b) the yield and price of the Debt Obligations relative
    to other debt securities of comparable quality and maturity, (c) income to
    the Certificateholders of the Trust and (d) the diversification of the
    Trust Portfolio, taking into account the availability in the market of
    issues in various industry classifications which meet the Trust's quality,
    rating, yield and price criteria.  Subsequent to the Evaluation Date, a
    Debt Obligation may cease to be rated or its rating may be reduced below
    that specified above.  Neither event requires an elimination of such Debt
    Obligation from the Trust but may be considered in the Sponsor's
    determination to direct the Trustees to dispose of the Debt Obligation. 
    For an interpretation of the Debt Obligation ratings see "Description of
    Debt Obligation Ratings."  See "Portfolio Supervision" for a summary of
    the factors considered in selecting substitute Debt Obligations. 

               Corporate debt obligations generally consist of bonds,
    debentures, notes or other straight debt obligations with fixed final
    maturity dates and, as used in this Prospectus, include taxable
    obligations issued or guaranteed by the United States or foreign
    governments, or political subdivisions thereof.  These obligations
    represent a liability of the issuer with respect to the payment of both
    interest and principal.  Corporate debt obligations enjoy a seniority in
    right of payment over all equity securities of the issuer, although
    certain debt obligations may be subordinated in right of payment to other
    debt obligations of the same issuer.  In addition, such debt obligations
    may be secured or unsecured and may be entitled to the benefits of a
    sinking fund. 

               Utility Issues.  Some of the Trust's Portfolio may be comprised
    of issues of the gas and electric public utility industry.  General
    problems of the gas and electric public utility industry include: 
    difficulty in obtaining timely and adequate rate increases; changes in the
    tax laws which adversely affect a utility's ability to operate profitably;
    rising costs of transportation to transport fossil fuels; the uncertainty
    of transmission service costs for both intrastate and interstate
    transactions; difficulty in financing large construction programs during
    an inflationary period; recent reductions in estimates of future demand
    for electricity and gas in certain areas of the country; restrictions on
    operations and increased cost and delays attributable to environmental
    considerations (including those arising under the Clean Air Act Amendments
    of 1977); uncertain availability and increased cost of capital,
    unavailability of fuel for electric generation at reasonable prices,
    including the steady rise in fuel costs and the costs associated with
    conversion to alternate fuel sources such as coal; availability and the
    cost of natural gas for resale, technical and cost factors and other
    problems associated with construction, licensing, regulation and
    operations of nuclear facilities for electric generation, including, among
    other considerations, the problems associated with the use of radioactive
    materials and the disposal of radioactive wastes, and the effect of energy
    conservation.

               There is no assurance that regulatory authorities will in the
    future grant rate increases or that any of these increases will be
    adequate to cover even operating and other expenses and debt service
    requirements.  Recently enacted and possible future regulatory legislation
    may make it even more difficult for these utilities to obtain adequate
    rate relief.  In addition, voters in many states have the ability to
    impose limits on rate adjustments (for example, by initiative or
    referendums) and any unexpected limitations could negatively affect the
    profitability of utilities whose budgets are planned far in advance. 
    Furthermore, changes in certain accounting standards currently under
    consideration by the Financial Accounting Standards Board (FASB-71) could
    cause significant writedowns of assets and reductions in earnings for many
    investor-owned utilities.  Certain of the issuers of the Debt Obligations
    in the Trust own or operate nuclear generating facilities.  Federal, state
    and municipal government authorities may from time to time review
    existing, and impose additional requirements governing the licensing,
    construction and operation of nuclear power plants, which may adversely
    affect the ability of such issuers to make payments of principal and
    interest on the Debt Obligations. 

               Foreign Issues.  Some of the Debt Obligations in the Portfolio
    may be issues of foreign obligors, which may involve investment risks that
    are different in some respects from an investment in a trust which invests
    only in debt obligations of domestic issuers, including future political
    and economic developments, the possible imposition of exchange controls,
    withholding taxes on interest income payable on such Debt Obligations or
    other foreign governmental restrictions (including expropriation,
    burdensome or confiscatory taxation and moratoria) which might adversely
    affect the payment of principal and interest on such Debt Obligations.  In
    addition, it may be more difficult to obtain and enforce a judgment
    against a foreign obligor, there may be less publicly available
    information about a foreign obligor than about a domestic issuer and
    foreign obligors generally operate in different regulatory environments
    than comparable domestic issuers and are not generally subject to uniform
    accounting, auditing and financial reporting standards, practices and
    requirements comparable to those applicable to domestic issuers.  Interest
    and principal on all of the foreign issues in the Portfolio of the Trust
    are payable in U.S. dollars.  To the Sponsor's knowledge, there are no
    withholding taxes applicable to such issues under existing law.  However,
    there can be no assurance that withholding taxes might not be imposed in
    the future. 

               Of the Debt Obligations in the Portfolio of the Trust, all are
    subject to redemption prior to their stated maturity dates pursuant to
    sinking fund or call provisions.  A sinking fund is a reserve fund
    appropriated specifically toward the retirement of a debt obligation.  A
    callable debt obligation is one which is subject to redemption or
    refunding prior to maturity at the option of the issuer.  A refunding is a
    method by which a debt obligation is redeemed at or before maturity from
    the proceeds of a new issue of debt obligations.  In general, call
    provisions are more likely to be exercised when the offering side
    evaluation of a debt obligation is at a premium over par than when it is
    at a discount from par.  A listing of the sinking fund and call
    provisions, if any, with respect to each of the Debt Obligations is
    contained under "Portfolio" in Part A.  Certificateholders will realize a
    gain or loss on the early redemption of such Debt Obligations, depending
    on whether the price of such Debt Obligations is at a discount from or at
    a premium over par at the time the Certificateholders purchase their
    Units. 

               The Trust consists of the Debt Obligations listed under
    "Portfolio" and any additional Debt Obligations acquired and held by the
    Trust pursuant to the provisions of the Trust Agreement together with
    accrued and undistributed interest thereon and undistributed and
    uninvested cash realized from the sale, redemption, maturity or other
    disposition of the Debt Obligations.  Neither the Sponsor nor the Trustees
    shall be liable in any way for any default, failure or defect in any of
    the Debt Obligations.  Because certain of the Debt Obligations from time
    to time may be redeemed or will mature in accordance with their terms or
    may be sold under certain circumstances, no assurance can be given that
    the Trust will retain for any length of time its present size and
    composition.  The Trust Agreement authorizes, but does not require, the
    Sponsor to direct the Trustees to reinvest the net proceeds of the sale of
    Debt Obligations in substitute Debt Obligations to the extent that such
    proceeds do not represent capital gains and are not required for the
    redemption of Units.  See "Trust Administration."  

                                  PUBLIC OFFERING

    Offering Price

               The secondary market Public Offering Price per Unit is computed
    by adding to the aggregate bid price of the Debt Obligations in the Trust
    divided by the number of Units outstanding an amount equal to 4.5% of the
    Public Offering Price, which is the same as 4.712% of the net amount
    invested in the Debt Obligations per Unit times the aggregate bid price of
    the Debt Obligations in the Trust.  A proportionate share of accrued
    interest on the Debt Obligations to the expected date of settlement for
    the Units is added to the Public Offering Price.  Accrued interest is the
    accumulated and unpaid interest on a Debt Obligation from the last day on
    which interest was paid and is accounted for daily by the Trust at the
    initial daily rate set forth under "Summary of Essential Information" in
    Part A.  This daily rate is net of estimated fees and expenses.  The
    secondary market Public Offering Price can vary on a daily basis from the
    amount stated in Part A in accordance with fluctuations in the prices of
    the Debt Obligations.  The price to be paid by each investor will be
    computed on the basis of an evaluation made on the day the Units are
    purchased.  The aggregate bid price evaluation of the Debt Obligations is
    determined in the manner set forth under "Trustee Redemption."

               The Evaluator may obtain current prices for the Debt
    Obligations from investment dealers or brokers (including the Sponsor)
    that customarily deal in corporate or government debt or from any other
    reporting service or source of information which the Evaluator deems
    appropriate. 

    Accrued Interest

               An amount of accrued interest which represents accumulated
    unpaid or uncollected interest on a Debt Obligation from the last day on
    which interest was paid thereon will be added to the Public Offering
    Price.  Since the Trust normally receives the interest on Debt Obligations
    twice a year and the interest on the Debt Obligations in the Trust is
    accrued on a daily basis, the Trust will always have an amount of interest
    earned but uncollected by, or unpaid to, the Trustees.  If a Certificate-
    holder sells or redeems all or a portion of his Units or if the Trust is
    terminated, he will receive at that time his proportionate share of the
    accrued interest computed to the settlement date in the case of sale or
    termination and to the date of tender in the case of redemption. 

    Employee Discounts

               Employees (and their immediate families) of Bear, Stearns & Co.
    Inc. and of any underwriter of the Trust, pursuant to employee benefit
    arrangements, may purchase Units of the Trust at a price equal to the bid
    side evaluation of the underlying securities in the Trust divided by the
    number of Units outstanding plus a reduced charge of $10.00 per Unit. 
    Such arrangements result in less selling effort and selling expenses than
    sales to employee groups of other companies.  Resales or transfers of
    Units purchased under the employee benefit arrangements may only be made
    through the Sponsor's secondary market, so long as it is being maintained.


    Distribution of Units

               The Sponsor has qualified and intends to continue to qualify
    the Units for sale in ten States through dealers who are members of the
    National Association of Securities Dealers, Inc.  Units may be sold to
    dealers at prices which represent a concession of $30 per Unit, subject to
    the Sponsor's right to change the dealers' concession from time to time. 
    Such Units may then be distributed to the public by the dealers at the
    Public Offering Price then in effect.  The Sponsor reserves the right to
    reject, in whole or in part, any order for the purchase of Units. 

    Sponsor's Profits

               The Sponsor will receive a gross commission on all units sold
    in the secondary market equal to the applicable sales charge on each
    transaction.  (See "Offering Price.")  In addition, in maintaining a
    market for the Units (see "Sponsor Repurchase"), the Sponsor will realize
    profits or sustain losses in the amount of any difference between the
    price at which it buys Units and the price at which it resells such Units.


               Participants in the "Total Reinvestment Plan" can designate a
    broker as the recipient of a dealer concession.  See "Total Reinvestment
    Plan." 

    Comparison of Public Offering Price and Redemption Price

               The secondary market Public Offering Price of Units will be
    determined on the basis of the bid prices of the Debt Obligations in the
    Trust.  The value at which Units may be redeemed will be determined on the
    basis of the current bid prices of such Debt Obligations without any sales
    charge.  On the Evaluation Date, the Public Offering Price per Unit (based
    on the bid side evaluation of the Debt Obligations in the Trust plus the
    sales charge) exceeded the Redemption Price per Unit (based upon the bid
    side evaluation of the Debt Obligations in the Trust) by the amount shown
    under "Summary of Essential Information" in Part A of this Prospectus. 
    For this reason, among others (including fluctuations in the market prices
    of Debt Obligations and the fact that the Public Offering Price includes
    the 4-1/2% sales charge), the amount realized by a Certificateholder upon
    any redemption of Units may be less than the price paid for such Units. 


              ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN


               Units of the Trust are offered to investors on a "dollar price"
    basis (using the computation method previously described under "Public
    Offering Price") as distinguished from a "yield price" basis often used in
    offerings of tax exempt bonds (involving the lesser of the yield as
    computed to maturity of bonds or to an earlier redemption date).  Since
    they are offered on a dollar price basis, the rate of return on an
    investment in Units of the Trust is measured in terms of "Estimated
    Current Return" and "Estimated Long Term Return". 

               Estimated Long Term Return is calculated by:  (1) computing the
    yield to maturity or to an earlier call date (whichever results in a lower
    yield) for each Bond in a Trust's portfolio in accordance with accepted
    bond practices, which practices take into account not only the interest
    payable on the Bond but also the amortization of premiums or accretion of
    discounts, if any; (2) calculating the average of the yields for the Bonds
    in each Trust's portfolio by weighing each Bond's yield by the market
    value of the Bond and by the amount of time remaining to the date to which
    the Bond is priced (thus creating an average yield for the portfolio of
    each Trust); and (3) reducing the average yield for the portfolio of each
    Trust in order to reflect estimated fees and expenses of that Trust and
    the maximum sales charge paid by Unitholders.  The resulting Estimated
    Long Term Return represents a measure of the return to Unitholders earned
    over the estimated life of each Trust.  For certain Trusts, the Estimated
    Long Term Return as of the day prior to the Evaluation Date is stated for
    each Trust under "Summary of Essential Information" in Part A.

               Estimated Current Return is computed by dividing the Estimated
    Net Annual Interest Income per Unit by the Public Offering Price per Unit. 
    In contrast to the Estimated Long Term Return, the Estimated Current
    Return does not take into account the amortization of premium or accretion
    of discount, if any, on the Bonds in the portfolios of the Trust. 
    Moreover, because interest rates on Bonds purchased at a premium are
    generally higher than current interest rates on newly issued bonds of a
    similar type with comparable rating, the Estimated Current Return per Unit
    may be affected adversely if such Bonds are redeemed prior to their
    maturity.  On the day prior to the Evaluation Date, the Estimated Net
    Annual Interest Income per Unit divided by the Public Offering Price
    resulted in the Estimated Current Return stated for the Trust under
    "Summary of Essential Information" in Part A.

               The Estimated Net Annual Interest Income per Unit of the Trust
    will vary with changes in the fees and expenses of the Trustee and the
    Evaluator applicable to the Trust and with the redemption, maturity, sale
    or other disposition of the Bonds in the Trust.  The Public Offering Price
    will vary with changes in the offering prices (bid prices in the case of
    the secondary market) of the Bonds.  Therefore, there is no assurance that
    the present Estimated Current Return or Estimated Long Term Return will be
    realized in the future.


                           RIGHTS OF CERTIFICATEHOLDERS

    Certificates

               Ownership of Units of the Trust is evidenced by registered
    Certificates executed by the Trustee and the Sponsor.  Certificates may be
    issued in denominations of one or more Units and will bear appropriate
    notations on their faces indicating which plan of distribution has been
    selected by the Certificateholder.  Certificates are transferable by
    presentation and surrender to the Trustee properly endorsed and/or
    accompanied by a written instrument or instruments of transfer.  Although
    no such charge is presently made or contemplated, the Trustee may require
    a Certificateholder to pay $2.00 for each Certificate reissued or
    transferred and any governmental charge that may be imposed in connection
    with each such transfer or interchange.  Mutilated, destroyed, stolen or
    lost Certificates will be replaced upon delivery of satisfactory indemnity
    and payment of expenses incurred. 

    Interest and Principal Distributions

               Interest received by the Trust is credited by the Trustees to
    an Interest Account.  Proceeds received from the maturity, redemption,
    sale or other disposition of the Debt Obligations are credited to a
    Principal Account. 
               Distributions to each Certificateholder from the Interest
    Account are computed as of the close of business on each Record Date for
    distribution on or shortly after the following Payment Date and consist of
    an amount substantially equal to one-twelfth or one-half of such Certifi-
    cateholder's pro rata share of the Estimated Net Annual Interest Income in
    the Interest Account, depending upon the applicable plan of distribution. 
    Distributions from the Principal Account will be computed as of each semi-
    annual Record Date, and will be made to the Certificateholders on or
    shortly after the next semi-annual Payment Date.  Proceeds representing
    principal received from the disposition of any of the Debt Obligations
    between a Record Date and a Payment Date which are not used for
    redemptions of Units or to purchase substitute Debt Obligations will be
    held in the Principal Account and not distributed until the second
    succeeding semi-annual Payment Date.  Persons who purchase Units between a
    Record Date and a Payment Date will receive their first distribution on
    the second Payment Date after such purchase. 

               Because interest payments are not received by the Trust at a
    constant rate throughout the year, interest distributions may be more or
    less than the amount credited to the Interest Account as of the Record
    Date.  For the purpose of minimizing fluctuations in the distributions
    from the Interest Account, the Trustee will advance sufficient funds as
    may be necessary to provide interest distributions of approximately equal
    amounts.  The Trustee shall be reimbursed, without interest, for these
    advances to the Interest Account.  Funds which are available for future
    distributions, payments of expenses and redemptions are in accounts which
    are non-interest bearing to Certificateholders and are available for use
    by the Trustee pursuant to normal banking procedures. 

               As of the first day of each month, the Trustee will deduct from
    the Interest Account and, to the extent funds are not sufficient therein,
    from the Principal Account, amounts necessary to pay the expenses of the
    Trust (as determined on the basis set forth under "Trust Expenses and
    Charges").  The Trustees also may withdraw from said accounts such
    amounts, if any, as they deem necessary to establish a reserve for any
    applicable taxes or other governmental charges that may be payable out of
    the Trust.  Amounts so withdrawn shall not be considered a part of the
    Trust's assets until such time as the Trustees shall return all or any
    part of such amounts to the appropriate accounts.  In addition, the
    Trustee may withdraw from the Interest and Principal Accounts such amounts
    as may be necessary to cover redemptions of Units. 

               The estimated monthly or semi-annual interest distribution per
    Unit will be in the amount shown under "Summary of Essential Information"
    and will change and may be reduced as Debt Obligations mature or are
    redeemed, exchanged or sold, or as expenses of the Trust fluctuate.  No
    distribution need be made from the Principal Account until the balance
    therein is an amount sufficient to distribute $1.00 per Unit. 

    Distribution Elections

               Interest is distributed monthly or semi-annually, depending
    upon the distribution plan applicable to the Unit purchased.  The Record
    Date for monthly distributions is the first day of each month and the
    Record Date for semi-annual distributions is the first day of each June
    and December.  The Payment Date will be the fifteenth day of each month
    following the respective Record Dates. 

               Certificateholders purchasing Units in the secondary market
    will initially receive distributions in accordance with the election of
    the prior owner.  Every October, the Trustee will furnish each Certifi-
    cateholder with a card to be returned to the Trustee on or before
    November 1 of such year.  When a Certificateholder who desires to change
    his current distribution plan returns his card and Certificate to the
    Trustee, the change will take effect December 2.  If the card and
    Certificate are not returned to the Trustee, the Certificateholder will be
    deemed to have elected to continue with the plan previously selected for
    the following 12 months. 

    Records

               The Trustee shall furnish Certificateholders in connection with
    each distribution a statement of the amount of interest, if any, and the
    amount of other receipts, if any, which are being distributed, expressed
    in each case as a dollar amount per Unit.  Within a reasonable time after
    the end of each calendar year (normally prior to January 31 of the
    succeeding year), the Trustee will furnish to each person who at any time
    during the calendar year was a Certificateholder of record, a statement
    showing (a) as to the Interest Account:  interest received (including
    amounts representing interest received upon any disposition of Debt
    Obligations), amounts reserved or paid for purchases of Debt Obligations
    or redemptions of Units, if any, deductions for fees and expenses of the
    Trust, and the balance remaining after such distributions and deductions,
    expressed both as a total dollar amount and as a dollar amount
    representing the pro rata share of each Unit outstanding on the last
    business day of such calendar year; (b) as to the Principal Account:  the
    dates of disposition of any Debt Obligations and the net proceeds received
    therefrom (excluding any portion representing accrued interest),
    deductions for payments of applicable taxes and fees and expenses of the
    Trust, amounts reserved or paid for purchases of Debt Obligations or paid
    for redemptions of Units, if any, and the balance remaining after such
    distributions and deductions, expressed both as a total dollar amount and
    as a dollar amount representing the pro rata share of each Unit
    outstanding on the last business day of such calendar year; (c) a list of
    the Debt Obligations held and the number of Units outstanding on the last
    business day of such calendar year; (d) a list of the Debt Obligations
    acquired or disposed of during such calendar year, showing which are
    Restricted Securities; (e) the Redemption Price per Unit based upon the
    last computation thereof made during such calendar year; and (f) amounts
    actually distributed during such calendar year from the Interest and
    Principal Accounts, separately stated, expressed both as total dollar
    amounts and as dollar amounts representing the pro rata share of each Unit
    outstanding. 

               The Trustee shall keep available for inspection by Certificate-
    holders at all reasonable times during usual business hours, books of
    record and account of its transactions as Trustee, including records of
    the names and addresses of Certificateholders, Certificates issued or
    held, a current list of Debt Obligations in the Portfolio and a copy of
    the Trust Agreement. 


                                    TAX STATUS


               The Trust has elected and intends to continue to qualify for
    the tax treatment applicable to "regulated investment companies" under the
    Internal Revenue Code of 1986, as amended (the "Code").  Although
    investment companies are subject to regulation under the Investment
    Company Act of 1940, the term "regulated investment company" involves no
    supervision or management by any government agency.  If the Trust
    qualifies as a "regulated investment company" and distributes 98 percent
    of its ordinary income and 98 percent of its net capital gain to Certifi-
    cateholders, it will not be subject to federal income tax or excise tax on
    such part of its net income or capital gains, if any, distributed to Cer-
    tificateholders.  The Trust Agreement requires current distribution to
    Certificateholders of the entire net income, net capital gains, if any,
    and proceeds (exclusive of net capital gains) of maturities, redemptions,
    sales or other dispositions of Debt Obligations (to the extent proceeds
    received from dispositions are not used to redeem Units or to purchase
    substitute Debt Obligations) of the Trust. 

               Distributions of net income attributable to interest and short-
    term capital gains will be taxable to Certificateholders as ordinary
    portfolio income.  It is anticipated that none of the distributions to
    Certificateholders will be eligible for the dividends-received deduction
    for corporations. 

               Distributions of long-term capital gains designated as such by
    the Trust will generally be taxable to Certificateholders as long-term
    capital gains except in the case of a dealer or financial institution.  As
    a result of the Tax Reform Act of 1986 (the "1986 Act"), long-term capital
    gains are generally taxed at the same rates applicable to ordinary income,
    although in certain circumstances an advantageous rate may apply to net
    capital gains realized by individuals.  Any gain from the disposition of a
    Debt Obligation issued after July 18, 1984 and acquired at a "market
    discount" will result in ordinary income, rather than capital gain, to the
    extent that the gain realized does not exceed the amount of accrued market
    discount.  If a Debt Obligation is acquired at a price less than the issue
    price plus the original issue discount includible in income by prior
    holders, market discount results.  A disposition of a Debt Obligation
    occurs when it is sold by the Trust, redeemed or paid at maturity.

               A Certificateholder will realize a taxable gain or loss when
    his Units are sold or redeemed for an amount different from his original
    cost after reduction for previous distributions that resulted in a
    reduction in the Certificateholder's basis.  Except in the case of a
    dealer or financial institution, such gain or loss will constitute either
    a long-term or short-term capital gain or loss depending upon the length
    of time the Certificateholder has held his Units.  A capital asset
    acquired on or after January 1, 1988 must be held for more than one year
    to qualify for long-term capital gain treatment.  A Certificateholder who
    disposes of a Unit at a loss before having held it for more than six
    months will experience a long-term capital loss, despite his short-term
    holding period, to the extent of any long-term capital gains previously
    distributed to him by the Trust during his holding period. 

               The 1986 Act added Section 67 of the Code, which disallows
    certain miscellaneous itemized deductions in computing the taxable income
    of individuals to the extent that the aggregate of such expenses does not
    exceed 2% of the individual's adjusted gross income.  Expenses for the
    production of income, such as investment advisory fees, are subject to
    this 2% floor.  The Revenue Reconciliation Act of 1989 permanently
    exempted shareholders of publicly offered regulated investment companies
    from the application of the 2% floor contained in Section 67(c).  However,
    counsel has advised that the Trust does not appear to qualify as a
    publicly offered regulated investment company within the meaning of Sec-
    tion 67(c), and therefore the expenses of the Trust will be treated as
    paid or incurred by the Certificateholders for this purpose, and will be
    subject to the disallowance required by Section 67.  

               The Code's requirements for the special tax treatment
    applicable to "regulated investment companies" are highly technical.  If
    the Trust fails to meet these requirements, the Trust will be taxable in
    general as a corporation and the Certificateholders will be taxable in
    general as its shareholders. 

               The federal tax status of each year's distributions is reported
    to Certificateholders.  Each Certificateholder is advised to consult his
    own tax adviser with respect to the foregoing and with respect to state
    and local taxation of distributions by the Trust. 


                                     LIQUIDITY

    Sponsor Repurchase

               The Sponsor, although not obligated to do so, has maintained
    and intends to continue to maintain a secondary market for the Units and
    continuously to offer to repurchase the Units at prices, subject to change
    at any time, based on the aggregate bid price of the Debt Obligations, as
    determined by the Evaluator on a daily basis, and will be the same as the
    redemption price.  See "Trustee Redemption."  Certificateholders who wish
    to dispose of their Units should inquire of the Sponsor prior to making a
    tender for redemption as described under "Offering Price."  The Sponsor
    may discontinue repurchases of Units if the supply of Units exceeds
    demand, or for other business reasons.  The date of repurchase is deemed
    to be the date on which Certificates representing Units are physically
    received in proper form by the Sponsor, Bear, Stearns & Co. Inc., 245 Park
    Avenue, New York, N.Y. 10167.  Units received after 4 P.M., New York Time,
    will be deemed to have been repurchased on the next business day.  In the
    event a market is not maintained for the Units a Certificateholder may be
    able to dispose of Units only by tendering them to the Trustee for
    redemption. 

               Prospectuses relating to certain other bond trusts indicate an
    intention by the Sponsor, subject to change, to repurchase units of those
    funds on the basis of a price higher than the bid prices of the Debt
    Obligations in the Trust.  Consequently, depending upon the prices
    actually paid, the secondary market repurchase price of other trusts may
    be computed on a somewhat more favorable basis than the repurchase price
    offered by the Sponsor for Units of the Trust, although in all bond trusts
    the purchase price per unit depends primarily on the value of the bonds in
    the trust portfolio. 

               Units purchased by the Sponsor in the secondary market may be
    re-offered for sale by the Sponsor at a price based on the aggregate bid
    price of the Debt Obligations plus a 4-1/2% sales charge (4.712% of the
    net amount invested) plus net accrued interest.  Any Units that are
    purchased by the Sponsor in the secondary market also may be redeemed by
    the Sponsor if it determines such redemption to be in its best interest. 

               The Sponsor may, under certain circumstances, as a service to
    Certificateholders, elect to purchase any Units tendered to the Trustee
    for redemption (see "Trustee Redemption," below).  For example, if in
    order to meet redemptions of Units the Trustee must dispose of Debt
    Obligations, and if such disposition cannot be made by the redemption date
    (seven calendar days after tender), the Sponsor may elect to purchase such
    Units.  Such purchase shall be made by payment to the Certificateholder
    not later than the close of business on the settlement date of an amount
    equal to the Redemption Price on the date of tender.  Any Units so
    purchased by the Sponsor will not be reoffered in the secondary market. 


    Trustee Redemption

               While it is anticipated that Units can be sold in the secondary
    market for an amount in excess of the Redemption Price (see "Sponsor
    Repurchase"), Units may also be tendered to the Trustee for redemption,
    upon proper delivery of Certificates representing such Units and payment
    of any relevant tax.  At the present time there are no specific taxes
    related to the redemption of Units.  No redemption fee will be charged by
    the Sponsor or the Trustee.  Units redeemed by the Trustee will be
    cancelled. 

               Certificates representing Units to be redeemed must be
    delivered to the Trustee and must be properly endorsed or accompanied by
    proper instruments of transfer with signature guaranteed (or by providing
    satisfactory indemnity, as in the case of lost, stolen or mutilated
    Certificates).  Thus, redemption of Units cannot be effected until
    Certificates representing such Units have been delivered by the person
    seeking redemption.  (See "Certificates.")  Certificateholders must sign
    exactly as their names appear on the faces of their Certificates.  In
    certain instances the Trustee may require additional documents such as,
    but not limited to, trust instruments, certificates of death, appointments
    as executor or administrator or certificates of corporate authority. 

               On the seventh calendar day following a tender for redemption,
    or, if such day is not a business day, on the first business day prior
    thereto, the Certificateholder will be entitled to receive in cash an
    amount for each Unit tendered equal to the Redemption Price per Unit
    computed as of the Evaluation Time on the date of tender.  The "date of
    tender" is deemed to be the date on which Units are received by the
    Trustee, except that with respect to Units received after the close of
    trading on the New York Stock Exchange, the date of tender is the next day
    on which such Exchange is open for trading, and such Units will be deemed
    to have been tendered to the Trustee on such day for redemption at the
    Redemption Price computed on that day. 

               Accrued interest paid on redemption shall be withdrawn from the
    Interest Account, or, if the balance therein is insufficient, from the
    Principal Account.  All other amounts paid on redemption shall be
    withdrawn from the Principal Account.  The Trustee is empowered to sell
    Debt Obligations in order to make funds available for redemptions.  Such
    sales, if required, could result in a sale of Debt Obligations by the
    Trustee at a loss.  To the extent Debt Obligations are sold, the size and
    diversity of the Trust will be reduced. 

               The Redemption Price per Unit is the pro rata share of each
    Unit in the Trust determined by the Trustee on the basis of (i) the cash
    on hand in the Trust or moneys in the process of being collected, (ii) the
    value of the Debt Obligations in the Trust based on the bid prices of such
    Debt Obligations and (iii) interest accrued thereon, less (a) amounts
    representing taxes or other governmental charges payable out of the Trust,
    (b) the accrued expenses of the Trust and (c) cash allocated for
    distribution to Certificateholders of record as of the business day prior
    to the evaluation being made.  The Evaluator may determine the value of
    the Debt Obligations in the Trust for purposes of redemption (1) on the
    basis of current bid prices of the Debt Obligations obtained from dealers
    or brokers who customarily deal in bonds comparable to those held by the
    Trust, (2) on the basis of bid prices for bonds comparable to any Debt
    Obligations for which bid prices are not available, (3) by determining the
    value of the Debt Obligations by appraisal, or (4) by any combination of
    the above. 

               The Trustee is irrevocably authorized in its discretion, if the
    Sponsor does not elect to purchase any Unit tendered for redemption or if
    the Sponsor tenders a Unit for redemption, in lieu of redeeming such Unit,
    to sell such Unit in the over-the-counter market for the account of the
    tendering Certificateholder at a price which will return to the Certifi-
    cateholder an amount in cash, net after deducting brokerage commissions,
    transfer taxes and other charges, equal to or in excess of the Redemption
    Price for such Unit.  The Trustee will pay the net proceeds of any such
    sale to the Certificateholder on the day he would otherwise be entitled to
    receive payment of the Redemption Price. 

               The Trustee reserves the right to suspend the right of
    redemption and to postpone the date of payment of the Redemption Price per
    Unit for any period during which the New York Stock Exchange is closed,
    other than customary weekend and holiday closings, or trading on that
    Exchange is restricted or during which (as determined by the Securities
    and Exchange Commission) an emergency exists as a result of which disposal
    or evaluation of the Debt Obligations is not reasonably practicable, or
    for such other periods as the Securities and Exchange Commission may by
    order permit.  The Trustee and the Sponsor are not liable to any person or
    in any way for any loss or damage which may result from any such
    suspension or postponement. 

               A Certificateholder who wishes to dispose of his Units should
    inquire of his bank or broker in order to determine if there is a current
    secondary market price in excess of the Redemption Price. 


                              TOTAL REINVESTMENT PLAN


               Certificateholders of the Trust (except Texas residents*) who
    select the semi-annual distribution plan have the option to automatically
    reinvest both interest income earned on Units in the Trust and principal,
    if any, distributed in connection with the Trust.  Under the Total
    Reinvestment Plan (the "Plan"), a semi-annual Certificateholder may elect
    to have all regular semi-annual interest and principal distributions with
    respect to his Units reinvested either in units of various series of "A
    Corporate Trust" which will have been created shortly before each semi-
    annual Payment Date (a "Primary Series") or, if units of a Primary Series
    are not available, in units of a previously formed series of the Trust
    which have been repurchased by the Sponsor in the secondary market,
    including the units being offered hereby (a "Secondary Series") (Primary
    Series and Secondary Series are hereafter collectively referred to as
    "Available Series").  June 15 and December 15 of each year are the "Plan
    Reinvestment Dates."  

    *     Texas residents may elect to participate in the "Total Reinvestment
          Plan for Texas Residents" hereinafter described.


    <PAGE>

               Under the Plan (subject to compliance with applicable blue sky
    laws), fractional units ("Plan Units") will be purchased from the Sponsor
    at a price equal to the aggregate offering price per Unit of the debt
    obligations in the Available Series Portfolio plus a sales charge equal to
    3.627% of the net amount invested in such debt obligations or 3-1/2% of
    the Reinvestment Price per Plan Unit, plus accrued interest, divided by
    one hundred (the "Reinvestment Price per Plan Unit").  All Plan Units will
    be sold at this reduced sales charge of 3-1/2% in comparison to the
    regular sales charge levied on primary and secondary purchases of Units in
    any series of "A Corporate Trust."  Participants in the Plan will have the
    opportunity to designate, in the Authorization Form for the Plan, the name
    of a broker to whom the Sponsor will allocate a sales commission of $0.15
    per Plan Unit, payable out of the 3-1/2% sales charge.  If no such
    designation is made, the Sponsor will retain the sales commission. 

               Under the Plan, the entire amount of a participant's income and
    principal distributions will be reinvested.  For example, a Certificate-
    holder who is entitled to receive $130.50 interest income from the Trust
    would acquire 13.05 Plan Units assuming that the Reinvestment Price per
    Plan Unit, plus accrued interest, was $10 (Ten Dollars). 

               A semi-annual Certificateholder may join the Plan at the time
    he invests in Units of the Trust or any time thereafter by delivering to
    the Trustee an Authorization Form which is available from brokers or the
    Sponsor.  In order that distributions may be reinvested on a particular
    Plan Reinvestment Date, the Authorization Form must be received by the
    Trustee not later than the 15th day of the month preceding such Date. 
    Authorization Forms not received in time for a particular Plan
    Reinvestment Date will be valid only for the second succeeding Plan
    Reinvestment Date.  Similarly, a participant may withdraw from the Plan at
    any time by notifying the Trustee (see below).  However, if written
    confirmation of withdrawal is not given to the Trustee prior to a
    particular distribution, the participant will be deemed to have elected to
    participate in the Plan with respect to that particular semi-annual
    distribution and his withdrawal would become effective for the next
    succeeding distribution. 

               Once delivered to the Trustee, an Authorization Form will
    constitute a valid election to participate in the Plan with respect to
    Units purchased in the Trust (and with respect to Plan Units purchased
    with the distributions from the Units purchased in the Trust) for each
    subsequent distribution as long as the Certificateholder continues to
    participate in the Plan.  However, if an Available Series should
    materially differ from the Trust in the opinion of the Sponsor, the
    authorization will be voided and participants will be provided with both a
    notice of the material change and a new Authorization Form which would
    have to be returned to the Trustee before the Certificateholder would
    again be able to participate in the Plan.  The Sponsor anticipates that a
    material difference which would result in a voided authorization would
    include such facts as the inclusion of debt obligations in the Available
    Series Portfolio which were not rated "A" or better by either Standard &
    Poor's Corporation, Moody's Investors Service, Inc. or Fitch Investors
    Service, Inc. or had, in the opinion of the Sponsor, similar credit
    characteristics, on the date such debt obligations were initially
    deposited in the Available Series Portfolio. 

               The Sponsor has the option at any time to use units of a
    Secondary Series to fulfill the requirements of the Plan in the event
    units of a Primary Series are not available either because a Primary
    Series is not then in existence or because the registration statement
    relating thereto is not declared effective in sufficient time to
    distribute final prospectuses to Plan participants (see below).  It should
    be noted that there is no assurance that the quality and diversification
    of the Debt Obligations in any Available Series or the estimated current
    return thereon will be similar to that of this Trust. 

               It is the Sponsor's intention that Plan Units will be offered
    on or about each semi-annual Record Date for determining who is eligible
    to receive distributions on the related Payment Date.  Such Record Dates
    are June 1 and December 1 of each year.  The Sponsor will send a current
    Prospectus relating to the Available Series being offered for a particular
    Plan Reinvestment Date along with a letter which reminds each participant
    that Plan Units are being purchased for him as part of the Plan unless he
    notifies the Trustee in writing by that Plan Reinvestment Date that he no
    longer wishes to participate in the Plan.  In the event a Primary Series
    has not been declared effective in sufficient time to distribute a final
    Prospectus relating thereto and there is no Secondary Series as to which a
    registration statement is currently effective, it is the Sponsor's
    intention to suspend the Plan and distribute to each participant his
    regular semi-annual distribution.  If the Plan is so suspended, it will
    resume in effect with the next Plan Reinvestment Date assuming units of an
    Available Series are then being offered. 

               To aid a participant who might desire to withdraw either from
    the Plan or from a particular distribution, the Trustee has established a
    toll free number (see below) for participants to use for notification of
    withdrawal, which must be confirmed in writing prior to the Plan
    Reinvestment Date.  Should the Trustee be so notified, it will make the
    appropriate cash disbursement.  Unless the withdrawing participant
    specifically indicates in his written confirmation that (a) he wishes to
    withdraw from the Plan for that particular distribution only, or (b) he
    wishes to withdraw from the Plan for less than all units of each series of
    "A Corporate Trust" which he might then own (and specifically identifies
    which series are to continue in the Plan), he will be deemed to have
    withdrawn completely from the Plan in all respects.  Once a participant
    withdraws completely, he will only be allowed to again participate in the
    Plan by submitting a new Authorization Form.  A sale or redemption of a
    portion of a participant's Plan Units will not constitute a withdrawal
    from the Plan with respect to the remaining Plan Units owned by such
    participant. 

               Unless a Certificateholder notifies the Trustee in writing to
    the contrary, any Certificateholder who has acquired Plan Units will be
    deemed to have elected the semi-annual plan of distribution and to
    participate in the Plan with respect to distributions made in connection
    with such Plan Units.  A participant who subsequently desires to have
    distributions made with respect to Plan Units delivered to him in cash may
    withdraw from the Plan with respect to such Plan Units and remain in the
    Plan with respect to units acquired other than through the Plan.  Assuming
    a participant has his distributions made with respect to Plan Units
    reinvested, all such distributions will be accumulated with distributions
    generated from the Units of the Trust used to purchase such additional
    Plan Units.  However, distributions related to units in other series of "A
    Corporate Trust" will not be accumulated with the foregoing distributions
    for Plan purchases.  Thus, if a person owns units in more than one series
    of "A Corporate Trust" (which are not the result of purchases under the
    Plan), distributions with respect thereto will not be aggregated for
    purchases under the Plan. 

               Although not obligated to do so, the Sponsor has maintained and
    intends to continue to maintain a market for the Plan Units and
    continuously to offer to purchase Plan Units at prices based upon the
    aggregate offering price of the Debt Obligations in the Available Series
    Portfolio during the initial offering of the Available Series, or at the
    aggregate bid price of the Debt Obligations in the Available Series if its
    initial offering has been completed.  The Sponsor may discontinue such
    purchases at any time.  The aggregate bid price of the underlying bonds
    may be expected to be less than the aggregate offering prices.  In the
    event that a market is not maintained for Plan Units, a participant
    desiring to dispose of his Plan Units may be able to do so only by
    tendering such Plan Units to the Trustee for redemption at the Redemption
    Price of full units in the Available Series corresponding to such Plan
    Units, which is based upon the aggregate bid price of the underlying debt
    obligations as described in the "A Corporate Trust" Prospectus for the
    Available Series in question.  The aggregate bid price of the underlying
    debt obligations may be expected to be less than the aggregate offering
    price.  If a participant wishes to dispose of his Plan Units, he should
    inquire of the Sponsor as to current market prices prior to making a
    tender for redemption to the Trustee. 

               Any participant may tender his Plan Units for redemption to the
    Available Series trust.  Participants may redeem Plan Units by making a
    written request to the Trustee, 101 Barclay Street, New York, New York
    10286, on the Redemption Form supplied by the Trustee.  The redemption
    price per Plan Unit will be determined as set forth in the "A Corporate
    Trust" Prospectus of the Available Series from which such Plan Unit was
    purchased following receipt of the request and adjusted to reflect the
    fact that it relates to a Plan Unit.  There is no charge for the
    redemption of Plan Units. 

               The Trust Agreement requires that the Trustee notify the
    Sponsor of any tender of Plan Units for redemption.  So long as the
    Sponsor is maintaining a bid in the secondary market, the Sponsor will
    purchase any Plan Units tendered to the Trustee for redemption by making
    payment therefor to the Certificateholder in an amount not less than the
    redemption price for such Plan Units on the date of tender not later than
    the day on which such Plan Units would otherwise have been redeemed by the
    Trustee.  Plan Units held by the Sponsor may be tendered to the Trustee
    for redemption as any other Units, provided that the Sponsor shall not
    receive for Plan Units purchased as set forth above a higher price than it
    paid, plus accrued interest. 

               Participants in the Plan will not receive individual
    certificates for their Plan Units unless the amount of Plan Units
    accumulated represents $1,000 principal amount of debt obligations
    underlying such Units and, in such case, a written request for
    certificates is made to the Trustee.  All Plan Units will be accounted for
    by the Trustee on a book entry system.  Each time Plan Units are purchased
    under the Plan, a participant will receive a confirmation stating his
    cost, number of Units purchased and estimated current return.  Questions
    regarding a participant's statement should be directed to the Trustee at
    1-800-431-8002.

               All expenses relating to the operation of the Plan are borne by
    the Sponsor.  Both the Sponsor and the Trustee reserve the right to
    suspend, modify or terminate the Plan at any time for any reason,
    including the right to suspend the Plan if the Sponsor is unable or
    unwilling to establish a Primary Series or is unable to provide Secondary
    Series units.  All participants will receive notice of any such
    suspension, modification or termination. 

    Total Reinvestment Plan for Texas Residents

               Except as specifically provided under this Section, and unless
    the context otherwise requires, all provisions and definitions contained
    under the heading "Total Reinvestment Plan" shall be applicable to the
    Total Reinvestment Plan for Texas Residents ("Texas Plan"). 

               Semi-annual Certificateholders of the Trust who are residents
    of Texas have the option prior to any semi-annual distribution to
    affirmatively elect to reinvest that distribution, including both interest
    and principal, if any, in an Available Series. 

               A resident of Texas who is a semi-annual Certificateholder may
    join the Texas Plan for any particular semi-annual distribution by
    delivering to the Trustee an Authorization Form For Texas Residents
    ("Texas Authorization Form") specifically mentioning the date of the
    particular semi-annual distribution he wishes to reinvest.  Prior to each
    semi-annual distribution, Texas Authorization Forms shall be sent by the
    Trustee to every Certificateholder who is a resident of Texas.  In the
    event that the Sponsor suspends the Plan or the Texas Plan, no Texas
    Authorization Forms shall be sent.  In order that distributions may be
    reinvested on a particular Plan Reinvestment Date, the Texas Authorization
    Form must be received by the Trustee on or before such Date.  Texas
    Authorization Forms not received in time for the Plan Reinvestment Date
    will be deemed void.  A participant who delivers a Texas Authorization
    Form to the Trustee may thereafter withdraw said authorization by
    notifying the Trustee at its toll free telephone number prior to a Plan
    Reinvestment Date.  Such notification of a withdrawal must be confirmed in
    writing prior to the Plan Reinvestment Date.  Under no circumstances shall
    a Texas Authorization Form be provided or accepted by the Trustee which
    provides for the reinvestment of distributions for more than one Plan
    Reinvestment Date. 

               On or about each semi-annual Record Date, the Sponsor will send
    a current Prospectus relating to the Available Series being offered on
    each Plan Reinvestment Date along with a letter incorporating a Texas
    Authorization Form which specifies the funds available for reinvestment,
    reminds each participant that no Plan Units will be purchased for him
    unless the Texas Authorization Form is received by the Trustee on or
    before that particular Plan Reinvestment Date, and states that the Texas
    Authorization Form is valid only for that particular semi-annual
    distribution.  If the Available Series should materially differ from the
    Trust, the participant will be provided with a notice of the material
    change and a new Texas Authorization Form which would have to be returned
    to the Trustee before the Certificateholder would again be able to
    participate in the Plan. 

               Any Certificateholder who has acquired Plan Units will be
    deemed to have elected the semi-annual plan of distribution with respect
    to such Units, but such Certificateholder will not be deemed to
    participate in the Plan for any particular semi-annual distribution until
    he delivers to the Trustee a Texas Authorization Form pertaining to those
    Plan Units. 


                               TRUST ADMINISTRATION

    Portfolio Supervision

               The Sponsor may direct the Trustees to dispose of Debt
    Obligations upon default in payment of principal or interest, institution
    of certain legal proceedings, default under other documents adversely
    affecting debt service, default in payment of principal or interest on
    other obligations of the same issuer or guarantor, or decline in price or
    the occurrence of other market or credit factors which in the opinion of
    the Sponsor would make the retention of such Debt Obligations in the Trust
    detrimental to the interest of the Certificateholders, or if the
    disposition of such Debt Obligations is necessary in order to maintain the
    qualification of the Trust as a regulated investment company under the
    Code.  If a default in the payment of principal or interest on any of the
    Debt Obligations occurs and if the Sponsor fails to instruct the Trustees
    to sell or hold such Debt Obligations, the Trust Agreement provides that
    the Trustees may sell such Debt Obligations. 

               The Sponsor is authorized by the Trust Agreement to direct the
    Trustees to accept or reject certain plans for the refunding or
    refinancing of any of the Debt Obligations.  Any debt obligations received
    in exchange or substitution will be held by the Trustees subject to the
    terms and conditions of the Agreement to the same extent as the Debt
    Obligations originally deposited.  Within five days after such deposit,
    notice of such exchange and deposit shall be given by the Trustee to each
    Certificateholder registered on the books of the Trustee, including an
    identification of the Debt Obligations eliminated and the Debt Obligations
    substituted therefor. 

               In order to maintain the sound investment character of the
    Trust, the Sponsor is also authorized to instruct the Trustees to reinvest
    the proceeds of the sale of any of the Debt Obligations (to the extent
    that such proceeds do not represent capital gains and are not required for
    the purposes of redemption of Units), as well as moneys held in the Trust
    to cover the purchase of Debt Obligations pursuant to contracts which have
    failed, in substitute Debt Obligations which satisfy certain conditions
    specified in the Trust Agreement including, among other conditions,
    requirements that the substitute Debt Obligations (a) be long-term bonds,
    debentures or notes issued primarily by corporations (whether secured or
    unsecured and whether senior or subordinated to other indebtedness);
    (b) consist solely of straight debt obligations without equity or other
    conversion features; (c) bear fixed maturity dates not less than ten years
    after the date of purchase, having no warrants or subscription privileges
    attached; (d) be payable in United States currency; and (e) be rated "A"
    or better by either Standard & Poor's Corporation, Moody's Investors
    Service, Inc. or Fitch Investors Service, Inc.  Such conditions also
    require that the purchase of the substitute Debt Obligations will not
    (A) disqualify the Trust as a "regulated investment company" under the
    Code, (B) result in more than 25% of the Portfolio of the Trust consisting
    of securities of a single issuer (or of two or more issuers which are
    "affiliated persons" as such term is defined in the Investment Company Act
    of 1940), (C) result in the Trust owning more than 50% of any single issue
    which has been registered under the Securities Act of 1933, or (D) result
    in more than 25% of the Portfolio of the Trust consisting of Restricted
    Securities.  Certificateholders will be notified promptly after any such
    substitution.  Interest on, capital gains from and the proceeds of the
    maturity or redemption of Debt Obligations may not be reinvested in
    substitute Debt Obligations but must be paid out to Certificateholders in
    accordance with the Trust Agreement. 


                    TRUST AGREEMENT, AMENDMENT AND TERMINATION


               The Trust Agreement may be amended by the Trustees, the Sponsor
    and the Evaluator without the consent of any of the Certificateholders: 
    (1) to cure any ambiguity or to correct or supplement any provision which
    may be defective or inconsistent; (2) to change any provision thereof as
    may be required by the Securities and Exchange Commission or any successor
    governmental agency; or (3) to make such other provisions in regard to
    matters arising thereunder as shall not adversely affect the interests of
    the Certificateholders. 

               The Trust Agreement may also be amended in any respect, or
    performance of any of the provisions thereof may be waived, with the
    consent of the holders of Certificates evidencing 66-2/3% of the Units
    then outstanding for the purpose of modifying the rights of Certificate-
    holders; provided that no such amendment or waiver shall reduce any Cer-
    tificateholder's interest in the Trust without his consent or reduce the
    percentage of Units required to consent to any such amendment or waiver
    without the consent of the holders of all Certificates.  The Trust
    Agreement may not be amended, without the consent of the holders of all
    Certificates then outstanding, to increase the number of Units issuable or
    to permit the acquisition of any debt obligations in addition to or in
    substitution for those initially deposited in the Trust, except in
    accordance with the provisions of the Agreement.  The Trustee shall
    promptly notify Certificateholders, in writing, of the substance of any
    such amendment. 

               The Agreement provides that the Trust shall terminate upon the
    maturity, redemption or other disposition, as the case may be, of the last
    of the Debt Obligations held in the Trust but in no event is it to
    continue beyond the expiration of 20 years after the death of the last
    survivor of six persons named in the Agreement.  If the value of the Trust
    shall be less than the minimum amount set forth in the "Summary of
    Essential Information", the Trustee may, in its discretion, and shall when
    so directed by the Sponsor or Co-Trustee, terminate the Trust.  The Trust
    may also be terminated at any time with the consent of the holders of
    Certificates representing 67% of the Units then outstanding.  In the event
    of termination, written notice thereof will be sent by the Trustee to all
    Certificateholders.  Within a reasonable period after termination, the
    Trustee must sell any Debt Obligations remaining in the Trust, and, after
    paying all expenses and charges incurred by the Trust, distribute to each
    Certificateholder, upon surrender for cancellation of his Certificate for
    Units, his pro rata share of the Interest and Principal Accounts. 

    The Sponsor

               The Sponsor, Bear, Stearns & Co. Inc., a Delaware corporation,
    is engaged in the underwriting, investment banking and brokerage business
    and is a member of the National Association of Securities Dealers, Inc.
    and all principal securities and commodities exchanges, including the New
    York Stock Exchange, the American Stock Exchange, the Midwest Stock
    Exchange and the Pacific Stock Exchange.  Bear Stearns maintains its
    principal business offices at 245 Park Avenue, New York, New York 10167
    and, since its reorganization from a partnership to a corporation in

    included herein is only for the purpose of informing investors as to the
    financial responsibility of the Sponsor and its ability to carry out its

               The Sponsor is liable for the performance of its obligations
    arising from its responsibilities under the Trust Agreement, but will be
    under no liability to Certificateholders for taking any action or
    refraining from taking any action, in good faith pursuant to the Trust
    Agreement, or for errors in judgment except in cases of its own willful
    misfeasance, bad faith, gross negligence or reckless disregard of its
    obligations and duties. 

               The Sponsor may resign at any time by delivering to the Trustee
    an instrument of resignation executed by the Sponsor and consented to by
    the Trustee.  Such resignation shall not become effective unless prior to
    or concurrently with the delivery thereof the Trustee shall have appointed
    a successor Sponsor to assume, with such compensation from the Trust as
    the Trustee may deem reasonable under the circumstances, the duties and
    obligations of the resigning Sponsor.  Any such successor Sponsor shall be
    satisfactory to the Trustee and, at the time of appointment, shall have a
    net worth of at least $1,000,000. 

               If at any time the Sponsor shall fail to perform any of its
    duties under the Trust Agreement or becomes incapable of acting or becomes
    bankrupt or its affairs are taken over by public authorities, then the
    Trustee may either (a) appoint a successor Sponsor; (b) act in the
    capacity of Sponsor and receive additional compensation at rates
    determined in accordance with the Trust Agreement; or (c) terminate the
    Trust Agreement and liquidate the Trust. 
    The Trustee

               The Trustee is The Bank of New York, a trust company organized
    under the laws of New York, having its offices at 101 Barclay Street, New
    York, New York 10286 (1-800-431-8002).  The Bank of New York is subject to
    supervision and examination by the Superintendent of Banks of the State of
    New York and the Board of Governors of the Federal Reserve System, and its
    deposits are insured by the Federal Deposit Insurance Corporation to the
    extent permitted by law.  The Trustee must be a banking corporation
    organized under the laws of the United States or any state which is
    authorized under such laws to exercise corporate trust powers and must
    have at all times an aggregate capital, surplus and undivided profits of
    not less than $5,000,000.  The duties of the Trustee are primarily
    ministerial in nature.  The Trustee did not participate in the selection
    of Securities for the portfolio of the Trust.

               The Trustee shall not be liable or responsible in any way for
    taking any action, or for refraining from taking any action, in good faith
    pursuant to the Trust Agreement, or for errors in judgment; or for any
    disposition of any moneys, Debt Obligations or Certificates in accordance
    with the Trust Agreement, except in cases of their own willful
    misfeasance, bad faith, gross negligence or reckless disregard of its
    obligations and duties; provided, however, that the Trustee shall not in
    any event be liable or responsible for any evaluation made by the
    Evaluator.  In addition, the Trustee shall not be liable for any taxes or
    other governmental charges imposed upon or in respect of the Debt
    Obligations or the Trust which either of them may be required to pay under
    current or future law of the United States or any other taxing authority
    having jurisdiction.  The Trustee shall not be liable for depreciation or
    loss incurred by reason of the sale by the Trustee of any of the Debt
    Obligations pursuant to the Trust Agreement. 

               For further information relating to the responsibilities of the
    Trustee under the Trust Agreement, see "Rights of Certificateholders". 

               The Trustee may resign by executing an instrument in writing
    and filing the same with the Sponsor, and mailing a copy of a notice of
    resignation to all Certificateholders.  In such an event the Sponsor is
    obligated to appoint a successor Trustee as soon as possible.  In
    addition, if the Trustee becomes incapable of acting or becomes bankrupt
    or its affairs are taken over by public authorities, the Sponsor may
    remove the Trustee and appoint a successor as provided in the Trust
    Agreement.  Notice of such removal and appointment shall be mailed to each
    Certificateholder by the Sponsor.  If upon resignation of the Trustee no
    successor has been appointed and has accepted the appointment within
    thirty days after notification, the Trustee may apply to a court of
    competent jurisdiction for the appointment of a successor.  The
    resignation or removal of the Trustee becomes effective only when the
    successor Trustee accepts its appointment as such or when a court of
    competent jurisdiction appoints a successor Trustee.  Upon execution of a
    written acceptance of such appointment by such successor Trustee, all the
    rights, powers, duties and obligations of the original Trustee shall vest
    in the successor. 

               Any corporation into which the Trustee may be merged or with
    which it may be consolidated, or any corporation resulting from any merger
    or consolidation to which the Trustee shall be a party, shall be the
    successor Trustee.  The Trustee must always be a banking corporation
    organized under the laws of the United States or any State and have at all
    times an aggregate capital, surplus and undivided profits of not less than
    $2,500,000. 

    The Evaluator

               The Evaluator is Interactive Data Services, Inc., a corporation
    organized and existing under the laws of the State of New York, with its
    main offices located at 99 Church Street, New York, New York 10007.

               The Trustee, Sponsor and Certificateholders may rely on any
    evaluation furnished by the Evaluator and shall have no responsibility for
    the accuracy thereof.  Determinations by the Evaluator under the Trust
    Agreement shall be made in good faith upon the basis of the best
    information available to it, provided, however, that the Evaluator shall
    be under no liability to the Trustee, the Sponsor, or Certificateholders
    for errors in judgment, except in cases of its own willful misfeasance,
    bad faith, gross negligence or reckless disregard of its obligations and
    duties. 

               The Evaluator may resign or may be removed by the Sponsor, and
    the Sponsor is to use its best efforts to appoint a satisfactory
    successor.  Such resignation or removal shall become effective upon the
    acceptance of appointment by the successor Evaluator.  If upon resignation
    of the Evaluator no successor has accepted appointment within thirty days
    after notice of resignation, the Evaluator may apply to a court of
    competent jurisdiction for the appointment of a successor. 


                            TRUST EXPENSES AND CHARGES


               At no cost to the Trust, the Sponsor has borne all the expenses
    of creating and establishing the Trust, including the cost of initial
    preparation and execution of the Trust Agreement, registration of the
    Trust under the Investment Company Act of 1940 and the Units under the
    Securities Act of 1933, preparation and printing of the Certificates, the
    fees of the Evaluator during the initial public offering and of Fitch
    Investors Service, Inc. for rating the Units of the Trust, legal expenses,
    advertising and selling expenses, initial fees and expenses of the Trustee
    and other out-of-pocket expenses. 

               The Sponsor will not charge the Trust a fee for its services as
    such.  See "Sponsor's  Profits". 

               The Trustee will receive for its ordinary recurring services to
    the Trust an annual fee in the respective amounts set forth under "Summary
    of Essential Information".  For a discussion of the services performed by
    the Trustee pursuant to its obligation under the Trust Agreement, see
    "Trust Administration" and "Rights of Certificateholders."  

               The Evaluator will receive, for each evaluation of the Debt
    Obligations in the Trust, a fee in the amount set forth under "Summary of
    Essential Information." 

               The Trustee's and Evaluator's fees are payable monthly as of
    the Record Date from the Interest Account to the extent funds are
    available and then from the Principal Account.  Both fees may be increased
    without approval of the Certificateholders by amounts not exceeding
    proportionate increases in consumer prices for services as measured by the
    United States Department of Labor's Consumer Price Index entitled "All
    Services Less Rent." 

               The following additional charges are or may be incurred by the
    Trust:  all expenses (including counsel fees) of the Trustee incurred in
    connection with their activities under the Trust Agreement, including the
    expenses and costs of any action undertaken by the Trustee to protect the
    Trust and the rights and interests of the Certificateholders; fees of the
    Trustee for any extraordinary services performed under the Trust
    Agreement; indemnification of the Trustee for any loss or liability
    accruing to them without gross negligence, bad faith or willful misconduct
    on their part, arising out of or in connection with their acceptance or
    administration of the Trust; indemnification of the Sponsor for any loss,
    liabilities and expenses incurred in acting as Sponsor of the Trust
    without gross negligence, bad faith or willful misconduct on its part; and
    all taxes and other governmental charges imposed upon the Debt Obligations
    or any part of the Trust (no such taxes or charges are being levied, made
    or, to the knowledge of the Sponsor, contemplated).  The above expenses,
    including the Trustee's fees, when paid by or owing to the Trustee are
    secured by a first lien on the Trust.  In addition, the Trustee is
    empowered to sell Debt Obligations in order to make funds available to pay
    all expenses. 


                      EXCHANGE PRIVILEGE AND CONVERSION OFFER

    Exchange Privilege

               Certificateholders may elect to exchange any or all of their
    Units of these Trusts for Units of one or more of any available series of
    Insured Municipal Securities Trust, Municipal Securities Trust, New York
    Municipal Trust, Mortgage Securities Trust, A Corporate Trust or Equity
    Securities Trust (upon receipt by the Equity Securities Trust of an
    appropriate exemptive order from the Securities & Exchange Commission)
    (the "Exchange Trusts") at a reduced sales charge as set forth below. 
    Under the Exchange Privilege, the Sponsor's repurchase price of the Units
    being surrendered and only after the initial offering period has been
    completed, will be based on the aggregate bid price of the Bonds in the
    particular Trust portfolio.  Units in an Exchange Trust then will be sold
    to the Certificateholder at a price based on the aggregate offer price of
    the Bonds in the Exchange Trust portfolio during the initial public
    offering period of the Exchange Trust (or for units of the Equity
    Securities Trust, based on the Market Value of the underlying securities
    in the Equity Trust portfolio); or, based on the aggregate bid price of
    the Bonds in the Exchange Trust portfolio if its initial public offering
    has been completed, plus accrued interest (or for units of the Equity
    Securities Trust, based on the Market Value of the underlying securities
    in the Equity Trust portfolio) and a reduced sales charge as set forth
    below.

               Except for unitholders who wish to exercise the Exchange
    Privilege within the first five months of their purchase of Units of
    Trust, the sales charge applicable to the purchase of units of an Exchange
    Trust shall be $15 per unit (or per 1,000 Units for the Mortgage
    Securities Trust or per 100 Units for the Equity Securities Trust)
    (approximately 1.5% of the price of each Exchange Trust unit (or 1,000
    Units for the Mortgage Securities Trust or 100 Units for the Equity
    Securities Trust)).  For unitholders who wish to exercise the Exchange
    Privilege within the first five months of their purchase of Units of
    Trust, the sales charge applicable to the purchase of units of an Exchange
    Trust shall be the greater of (i) $15 per unit (or per 1,000 Units for the
    Mortgage Securities Trust or per 100 Units for the Equity Securities
    Trust), or (ii) an amount which when coupled with the sales charge paid by
    the unitholder upon his original purchase of Units of the Trust at least
    equals the sales charge applicable in the direct purchase of units of an
    Exchange Trust.  The Exchange Privilege is subject to the following
    conditions:

               (1)  The Sponsor must be maintaining a secondary market in both
          the Units of the Trust held by the Certificateholder and the Units
          of the available Exchange Trust.  While the Sponsor has indicated
          its intention to maintain a market in the Units of all Trusts
          sponsored by it, the Sponsor is under no obligation to continue to
          maintain a secondary market and therefore there is no assurance that
          the Exchange Privilege will be available to a Certificateholder at
          any specific time in the future.  At the time of the
          Certificateholder's election to participate in the Exchange
          Privilege, there also must be Units of the Exchange Trust available
          for sale, either under the initial primary distribution or in the
          Sponsor's secondary market.

               (2)  Exchanges will be effected in whole units only.  Any
          excess proceeds from the Units surrendered for exchange will be
          remitted and the selling Certificateholder will not be permitted to
          advance any new funds in order to complete an exchange.  Units of
          the Mortgage Securities Trust may only be acquired in blocks of
          1,000 Units.  Units of the Equity Securities Trust may only be
          acquired in blocks of 100 Units.

               (3)  The Sponsor reserves the right to suspend, modify or
          terminate the Exchange Privilege.  The Sponsor will provide
          unitholders of the Trust with 60 days' prior written notice of any
          termination or material amendment to the Exchange Privilege,
          provided that, no notice need be given if (i) the only material
          effect of an amendment is to reduce or eliminate the sales charge
          payable at the time of the exchange, to add one or more series of
          the Trust eligible for the Exchange Privilege or to delete a series
          which has been terminated from eligibility for the Exchange
          Privilege, (ii) there is a suspension of the redemption of units of
          an Exchange Trust under Section 22(e) of the Investment Company Act
          of 1940, or (iii) an Exchange Trust temporarily delays or ceases the
          sale of its units because it is unable to invest amounts effectively
          in accordance with its investment objectives, policies and
          restrictions.  During the 60 day notice period prior to the
          termination or material amendment of the Exchange Privilege
          described above, the Sponsor will continue to maintain a secondary
          market in the units of all Exchange Trusts that could be acquired by
          the affected unitholders.  Unitholders may, during this 60 day
          period, exercise the Exchange Privilege in accordance with its terms
          then in effect.  In the event the Exchange Privilege is not
          available to a Certificateholder at the time he wishes to exercise
          it, the Certificateholder will immediately be notified and no action
          will be taken with respect to his Units without further instructions
          from the Certificateholder.

               To exercise the Exchange Privilege, a Certificateholder should
    notify the Sponsor of his desire to exercise his Exchange Privilege.  If
    Units of a designated, outstanding series of an Exchange Trust are at the
    time available for sale and such Units may lawfully be sold in the state
    in which the Certificateholder is a resident, the Certificateholder will
    be provided with a current prospectus or prospectuses relating to each
    Exchange Trust in which he indicates an interest.  He may then select the
    Trust or Trusts into which he desires to invest the proceeds from his sale
    of Units.  The exchange transaction will operate in a manner essentially
    identical to a secondary market transaction except that units may be
    purchased at a reduced sales charge.

               Example:  Assume that after the initial public offering has
    been completed, a Certificateholder has five units of a Trust with a
    current value of $700 per unit which he has held for more than 5 months
    and the Certificateholder wishes to exchange the proceeds for units of a
    secondary market Exchange Trust with a current price of $725 per unit. 
    The proceeds from the Certificateholder's original units will aggregate
    $3,500.  Since only whole units of an Exchange Trust may be purchased
    under the Exchange Privilege, the Certificateholder would be able to
    acquire four units (or 4,000 Units of the Mortgage Securities Trust or 400
    Units of the Equity Securities Trust) for a total cost of $2,960 ($2,900
    for unit and $60 for the sales charge).  The remaining $540 would be
    remitted to the Certificateholder in cash.  If the Certificateholder
    acquired the same number of units at the same time in a regular secondary
    market transaction, the price would have been $3,068.80 ($2,900 for units
    and $168.80 for the sales charge, assuming a 5 1/2% sales charge times the
    public offering price).

    The Conversion Offer

               Unit owners of any registered unit investment trust for which
    there is no active secondary market in the units of such trust (a
    "Redemption Trust") may elect to redeem such units and apply the proceeds
    of the redemption to the purchase of available Units of one or more series
    of A Corporate Trust, Municipal Securities Trust, Insured Municipal
    Securities Trust, Mortgage Securities Trust, New York Municipal Trust or
    Equity Securities Trust (upon receipt by the Equity Securities Trust of an
    appropriate exemptive order from the Securities and Exchange Commission)
    sponsored by Bear, Stearns & Co. Inc. or the Sponsor (the "Conversion
    Trusts") at the Public Offering Price for units of the Conversion Trust
    based on a reduced sales charge as set forth below.  Under the Conversion
    Offer, units of the Redemption Trust must be tendered to the trustee of
    such trust for redemption at the redemption price, which is based upon the
    aggregate bid side evaluation of the underlying bonds in such trust and is
    generally about 1 1/2% to 2% lower than the offering price for such bonds
    (or for units of Equity Securities Trust, based on the Market Value of the
    underlying securities in the Equity Trust portfolio).  The purchase price
    of the units will be based on the aggregate offer price of the underlying
    bonds in the Conversion Trust portfolio (or for units of the Equity
    Securities Trust, based on the Market Value of the underlying securities
    in the Equity Trust portfolio) during its initial offering period; or, at
    a price based on the aggregate bid price of the underlying bonds if the
    initial public offering of the Conversion Trust has been completed, plus
    accrued interest (or for units of the Equity Securities Trust, based on
    the Market Value of the underlying securities in the Equity Trust
    portfolio) and a sales charge as set forth below.

               Except for unitholders who wish to exercise the Conversion
    Offer within the first five months of their purchase of units of a
    Redemption Trust, the sales charge applicable to the purchase of Units of
    the Conversion Trust shall be $15 per Unit (or per 1,000 Units for the
    Mortgage Securities Trust or per 100 Units for the Equity Securities
    Trust).  For unitholders who wish to exercise the Conversion Offer within
    the first five months of their purchase of units of a Redemption Trust,
    the sales charge applicable to the purchase of Units of a Conversion Trust
    shall be the greater of (i) $15 per Unit (or per 1,000 Units for the
    Mortgage Securities Trust or per 100 Units for the Equity Securities
    Trust) or (ii) an amount which when coupled with the sales charge paid by
    the unitholder upon his original purchase of units of the Redemption Trust
    at least equals the sales charge applicable in the direct purchase of
    Units of a Conversion Trust.  The Conversion Offer is subject to the
    following limitations:

               (1)  The Conversion Offer is limited only to unit owners of any
          Redemption Trust, defined as a unit investment trust for which there
          is no active secondary market at the time the Certificateholder
          elects to participate in the Conversion Offer.  At the time of the
          unit owner's election to participate in the Conversion Offer, there
          also must be available units of a Conversion Trust, either under a
          primary distribution or in the Sponsor's secondary market.

               (2)  Exchanges under the Conversion Offer will be effected in
          whole units only.  Unit owners will not be permitted to advance any
          new funds in order to complete an exchange under the Conversion
          Offer.  Any excess proceeds from units being redeemed will be
          returned to the unit owner.  Units of the Mortgage Securities Trust
          may only be acquired in blocks of 1,000 units.

               (3)  The Sponsor reserves the right to modify, suspend or
          terminate the Conversion Offer at any time without notice to unit
          owners of Redemption Trusts.  In the event the Conversion Offer is
          not available to a unit owner at the time he wishes to exercise it,
          the unit owner will be notified immediately and no action will be
          taken with respect to his units without further instruction from the
          unit owner.  The Sponsor also reserves the right to raise the sales
          charge based on actual increases in the Sponsor's costs and expenses
          in connection with administering the program, up to a maximum sales
          charge of $20 per unit (or per 1,000 units for the Mortgage
          Securities Trust or per 100 Units for the Equity Securities Trust).

               To exercise the Conversion Offer, a unit owner of a Redemption
    Trust should notify his retail broker of his desire to redeem his
    Redemption Trust Units and use the proceeds from the redemption to
    purchase Units of one or more of the Conversion Trusts.  If Units of a
    designated, outstanding series of a Conversion Trust are at that time
    available for sale and if such Units may lawfully be sold in the state in
    which the unit owner is a resident, the unit owner will be provided with a
    current prospectus or prospectuses relating to each Conversion Trust in
    which he indicates an interest.  He then may select the Trust or Trusts
    into which he decides to invest the proceeds from the sale of his Units. 
    The transaction will be handled entirely through the unit owner's retail
    broker.  The retail broker must tender the units to the trustee of the
    Redemption Trust for redemption and then apply the proceeds to the
    redemption toward the purchase of units of a Conversion Trust at a price
    based on the aggregate offer or bid side evaluation per Unit of the
    Conversion Trust, depending on which price is applicable, plus accrued
    interest and the applicable sales charge.  The certificates must be
    surrendered to the broker at the time the redemption order is placed and
    the broker must specify to the Sponsor that the purchase of Conversion
    Trust Units is being made pursuant to the Conversion Offer.  The unit
    owner's broker will be entitled to retain $5 of the applicable sales
    charge.

               Example:  Assume a unit owner has five units of a Redemption
    Trust which has held for more than 5 months with a current redemption
    price of $675 per unit based on the aggregate bid price of the underlying
    bonds and the unit owner wishes to participate in the Conversion Offer and
    exchange the proceeds for units of a secondary market Conversion Trust
    with a current price of $750 per Unit.  The proceeds from the unit owner's
    redemption of units will aggregate $3,375.  Since only whole units of a
    Redemption Trust may be purchased under the Conversion Offer, the unit
    owner will be able to acquire four units of the Conversion Trust (or 4,000
    units of the Mortgage Securities Trust or 400 Units of the Equity
    Securities Trust) for a total cost of $2,860 ($2,800 for units and $60 for
    the sales charge).  The remaining $515 would be remitted to the unit owner
    in cash.  If the unit owner acquired the same number of Conversion Trust
    units at the same time in a regular secondary market transaction, the
    price would have been $2,962.96 ($2,800 for units and $162.96 sales
    charge, assuming a 5 1/2% sales charge times the public offering price).

    Description of the Exchange Trusts
       and the Conversion Trusts

               A Corporate Trust may be an appropriate investment vehicle for
    an investor who is more interested in a higher current return on his
    investment (although taxable) than a tax-exempt return (resulting from the
    fact that the current return from taxable fixed income securities is
    normally higher than that available from tax-exempt fixed income
    securities).  Municipal Securities Trust and New York Municipal Trust may
    be appropriate investment vehicles for an investor who is more interested
    in tax-exempt income.  The interest income from New York Municipal Trust
    is, in general, also exempt from New York State and local New York income
    taxes, while the interest income from Municipal Securities Trust is
    subject to applicable New York State and local taxes, except for that
    portion of the income attributable to New York obligations in the Trust
    Portfolio, if any.  The interest income from each State Trust of the
    Municipal Securities Trust, Multi-State Series is, in general, exempt from
    state and local taxes when held by residents of the state where the
    issuers of bonds in such State Trusts are located.  The Insured Municipal
    Securities Trust combines the advantages of providing interest income free
    from regular federal income tax under existing law with the added safety
    of irrevocable insurance on the underlying obligations.  Insured Navigator
    Series further combines the advantages of providing interest income free
    from regular federal income tax and state and local taxes when held by
    residents of the state where issuers of bonds in such State Trusts are
    located with the added safety of irrevocable insurance on the underlying
    obligations.  Mortgage Securities Trust offers an investment vehicle for
    investors who are interested in obtaining safety of capital and a high
    level of current distribution of interest income through investment in a
    fixed portfolio of collateralized mortgage obligations.  Equity Securities
    Trust offers investors an opportunity to achieve capital appreciation
    together with a high level of current income.

       Privilege and the Conversion Offer

               A surrender of units pursuant to the Exchange Privilege and the
    Conversion Offer normally will constitute a "taxable event" to the Cer-
    tificateholder under the Code.  The Certificateholder will generally
    recognize a tax gain or loss that will constitute either a long-term or
    short-term capital gain or loss, depending on the length of time the units
    have been held and other factors.  Under present law, capital gains are
    generally taxed at the same rates applicable to ordinary income, although
    a preferential rate is available in certain circumstances.  (See "Tax
    Status").  A Certificateholder's tax basis in the Units acquired pursuant
    to the Exchange Privilege or Conversion Offer will be equal to the
    purchase price of such Units.  (See "Tax Status").  Investors should
    consult their own tax advisors as to the tax consequences to them of
    exchanging or redeeming units and participating in the Exchange Privilege
    or Conversion Offer. 


                                   OTHER MATTERS

    Legal Opinions

               The legality of the Units originally offered and certain
    matters relating to federal tax law have been passed upon by
    Messrs. Battle Fowler, 280 Park Avenue, New York, New York 10017, as
    counsel for the Sponsor.  On the initial date of deposit, Messrs. Booth &
    Baron acted as counsel for the Trustee.

    Independent Auditors

               The financial statements of the Trust included in Part A of
    this Prospectus as of the date set forth in Part A have been examined by
    KPMG Peat Marwick, independent certified public accountant, for the
    periods indicated in its reports appearing herein.  The financial
    statements examined by KPMG Peat Marwick have been so included in reliance
    on its reports given upon its authority as experts in accounting and
    auditing. 


                      DESCRIPTION OF DEBT OBLIGATION RATINGS*

    Standard & Poor's Corporation

               A brief description of the applicable Standard & Poor's
    Corporation rating symbols and their meanings is as 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 of creditworthiness may take
    into consideration obligors such as guarantors, insurers, or lessees. 

    *     As described by the rating agencies.


    <PAGE>
               The bond rating is not a recommendation to purchase or sell a
    security, inasmuch as it does not comment as to market price. 

               The ratings are based on current information furnished to
    Standard & Poor's by the issuer and obtained by Standard & Poor's from
    other sources it considers reliable.  The ratings may be changed,
    suspended or withdrawn as a result of changes in, or unavailability of,
    such information. 

               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 arrangement
    under the laws of bankruptcy and other laws affecting creditors' rights. 

               AAA --  This is the highest rating assigned by Standard &
    Poor's to a debt obligation and indicates an extremely strong capacity to
    pay principal and interest. 

               AA --  Bonds rated AA also qualify as high-quality debt
    obligations.  Capacity to pay principal and interest is very strong, and
    they differ from AAA issues only in small degrees. 

               A --  Bonds rated A have a strong capacity to pay principal and
    interest, although they are somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions. 

               BBB --  Bonds rated BBB are regarded as having an adequate
    capacity to pay principal and interest.  Whereas they normally exhibit
    adequate protection parameters, adverse economic conditions or changing
    circumstances are more likely to lead to a weakened capacity to pay
    principal and interest for bonds in this category than for bonds in the A
    category. 

               Plus (+) or Minus (-):  To provide more detailed indications of
    credit quality, the ratings from "AA" to "BB" may be modified by the
    addition of a plus or minus sign to show relative standing within the
    major rating categories. 

               P --  Provisional Ratings (Prov.) following a rating indicates
    the rating is provisional which assumes the successful completion of the
    project being financed by the issuance of 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,
    makes no comment on the likelihood of, or the risk of default upon failure
    of, such completion.  Accordingly, the investor should exercise his own
    judgment with respect to such likelihood and risk. 

    Moody's Investors Service, Inc. 

               A brief description of the applicable Moody's Investors
    Service, Inc.'s rating symbols and their meanings is as 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. 

               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. 

               A --  Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper medium grade obligations. 
    Factors giving security to principal and interest are considered adequate
    but elements may be present which suggest a susceptibility to impairment
    sometime in the future. 

               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 the Baa-rated bonds is more
    sensitive to changes in economic circumstances.  Aside from occasional
    speculative factors and the aforementioned economic circumstances applying
    to some bonds of this Class, Baa market valuations move in parallel with
    Aaa, Aa and A obligations during periods of economic normalcy, except in
    instances of oversupply.

               Those bonds in the A and Baa group which Moody's believes
    possess the strongest investment attributes are designated by the symbol
    A 1 and Baa 1.  Other A bonds comprise the balance of the group.  These
    rankings (1) designate the bonds which offer the maximum in security
    within their quality group, (2) designate bonds which can be bought for
    possible upgrading in quality and (3) additionally afford the investor an
    opportunity to gauge more precisely the relative attractiveness of
    offerings in the marketplace. 

               Moody's applies numerical modifiers, 1, 2 and 3 in each generic
    rating classification from Aa through B in its corporate bond rating
    system.  The modifier 1 indicates that the security ranks in the higher
    end of its generic rating 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 debt obligations secured by (a) earnings of projects under
    construction, (b) earnings of projects unseasoned in operating experience,
    (c) rentals which begin when facilities are completed, or (d) payments to
    which some other limiting condition attaches.  Rating denotes probable
    credit stature upon completion of construction or elimination of basis of
    condition.
