                             MORTGAGE SECURITIES TRUST

                                   CMO SERIES 1

    __________________________________________________________________
       
              The Trust is a unit investment trust designated Mortgage Series
    Trust, CMO Series 1 (the "Trust").  The Trust consists of an underlying
    portfolio of collateralized mortgage obligations ("CMOs" or "Securities")
    and were formed to obtain safety of capital and provide a high level of
    current distributions of interest income.  The Trust seeks to obtain a
    higher yield than fixed income investments with comparable AAA ratings. 
    An investment in the Trust entails differing degrees of risk.  The Trust
    seeks to achieve its objectives through investment in a fixed portfolio of
    CMOs which may have been issued as debt obligations of a trust or
    corporation or which may represent certificated interests of beneficial
    ownership in pools of mortgage-backed securities.  All of the CMOs in the
    portfolio are backed by underlying mortgage-backed securities which are
    pledged as collateral to secure payment of principal and interest on the
    CMOs.  Each of these underlying mortgage-backed securities is guaranteed
    as to the payment of principal and interest by the Government National
    Mortgage Association ("GNMA"), the Federal National Mortgage Association
    ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC").  All of
    the CMOs in the Trust are issued by GNMA, FNMA or FHLMC or are otherwise
    rated AAA by Standard & Poor's and, therefore, the Units of the Trust are
    rated AAA by Standard & Poor's Corporation.  The Units of the Trust are
    not, however, guaranteed by GNMA, FNMA, FHLMC, the United States or any of
    its agencies.  The full faith and credit of the United States is pledged
    to the payment of all amounts guaranteed by GNMA.  However, payments
    guaranteed by FNMA and FHLMC are not guaranteed by the United States and
    neither the CMOs in the Trust nor any underlying Fannie Maes or Freddie
    Macs constitute a debt obligation of the United States or any of its
    agencies.  The Sponsors are Bear, Stearns & Co. and Gruntal & Co.,
    Incorporated.  The value of the Units will fluctuate with the value of the
    CMOs in the portfolio.  Both the Estimated Current Return and the
    Estimated Long Term Return are subject to fluctuations with changes in
    portfolio composition, principal payments and prepayments, changes in the
    market value of the CMOs in the portfolio and changes in fees and
    expenses.  Minimum purchase:  1,000 Units.

              THE TRUST.  The Trust is a unit investment trust and was formed
    to obtain safety of capital and a high level of current distributions of
    interest income through investments in a fixed portfolio of CMOs.  A CMO
    is a multiclass bond backed by a pool of mortgage pass-through securities
    or mortgage loans.  CMOs are also known as "real estate mortgage
    investment conduits" (REMICs).  As a result of the 1986 Tax Reform Act,
    most CMOs are issued in REMIC form to create a certain tax advantage for
    the issuer.  The terms CMO and REMIC are used interchangeably.  The Trust
    seeks to obtain a higher yield than fixed income investments with
    comparable AAA ratings.

              All of the CMOs in the Trust are backed by underlying mortgage-
    backed securities which are pledged as collateral to secure payment of
    principal and interest on the CMOs.  Each of these mortgage-backed
    securities is guaranteed as to the payment of principal and interest by
    either the Government National Mortgage Association ("GNMA"), the Federal
    National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
    Corporation ("FHLMC").  All of the CMOs in the Trust are issued by GNMA,
    FNMA or FHLMC or are otherwise rated AAA by Standard & Poor's Corporation
    ("Standard & Poor's") and therefore, the Units of the Trust are rated AAA
    by Standard & Poor's.  There can be no assurance that the Trust's
    investment objectives can be achieved.  Investments in the Trust should be
    made with an understanding of the risks inherent in an investment in CMOs. 
    (See "The Trust--Special Risk Considerations" in this Part A.)  Each Unit
    of the Trust represents an undivided interest in the principal and net
    income of the Trust in the ratio of one thousand Units for the indicated
    principal amount of Securities in the Trust.  (See "The Trust--
    Organization" in Part B of this Prospectus.)  (For the specific number of
    Units in the Trust, see "Summary of Essential Information" in this
    Part A.)

              Generally, CMOs are designed to provide a substantial degree of
    prepayment and reinvestment risk protection as compared to other mortgage
    related securities.  The CMOs may have been issued as debt obligations of
    a trust or corporation or as certificated interests representing
    beneficial ownership in a pool of mortgage-backed securities (See "The
    Trusts--The Securities" in Part B of this Prospectus for further
    description and examples) which trust, corporation or pool may have been
    established for the sole purpose of issuing CMOs by any of GNMA, FNMA or
    FHLMC or by a private business organization.  Such private business
    organizations are typically single-purpose corporations established by
    mortgage-banking institutions for the sole purpose of issuing CMOs.  Any
    CMOs in the Trust that have been issued by private business organizations
    have been rated AAA by Standard & Poor's.  The sole assets of the issuers
    of the CMOs are the underlying mortgage-backed securities.  If the
    collateral securing the Securities of these issuers is insufficient to
    make payments on those Securities, it is unlikely that any other assets of
    these issuers will be available for payment of the deficiency.  The
    underlying mortgage-backed securities which are pledged as collateral to
    secure the payment of principal and interest on the CMOs may be (i) "fully
    modified pass-through" mortgage-backed certificates, guaranteed by GNMA
    ("Ginnie Maes"), (ii) mortgage pass-through certificates guaranteed by
    FNMA ("Fannie Maes") or (iii) mortgage participation certificates
    guaranteed by FHLMC ("Freddie Macs").  The full faith and credit of the
    United States is pledged to the payment of all amounts guaranteed by GNMA. 
    However, payments guaranteed by FNMA and FHLMC are not guaranteed by the
    United States and neither the CMOs in the Trust nor any underlying Fannie
    Maes or Freddie Macs constitute a debt or obligation of the United States
    or any of its agencies.  The Units of the Trust, as such, are not
    guaranteed by any of GNMA, FNMA, FHLMC, the United States or any of its
    agencies.  Additionally, CMOs that are issued by GNMA, FNMA or FHLMC or by
    any entity established by GNMA, FNMA or FHLMC are guaranteed as to payment
    of principal and interest by GNMA, FNMA or FHLMC, respectively.  The
    guaranty obligations of GNMA with respect to any Ginnie Maes or any CMOs
    are supported by the full faith and credit of the United States.  However,
    the guaranty of obligations of FNMA and FHLMC with respect to any Fannie
    Maes or Freddie Macs or any CMOs are obligations of FNMA and FHLMC only
    (limited by their respective credit capabilities) and are not supported by
    the full faith and credit of the United States or any other governmental
    entity.
       
              CMO Structure.  CMOs are generally issued as a series of
    different classes.  An issue of CMOs generally is backed by a larger
    number of mortgages than a pool of Ginnie Maes, Fannie Maes or Freddie
    Macs, thus allowing greater statistical prediction of prepayment
    characteristics.  Interest and principal payments on the mortgages
    underlying any series will first be applied to meet the interest payment
    requirements of each class in the series other than any class in respect
    of which interest accrues but is not paid or any "principal only" class. 
    Principal payments on the underlying mortgages are thereafter generally
    applied to pay the principal amount of the class that has the earliest
    maturity date.  Once that class is retired, the principal payments on the
    underlying mortgages are applied to the class with the next earliest
    maturity date.  This is repeated until all classes are paid.  Therefore,
    while each class of CMOs remains subject to prepayment as the underlying
    mortgages prepay, structuring several classes of CMOs in the stream of
    principal payments allows a more predictable estimate of the period of
    time when any one class is likely to be repaid.  The estimate can be even
    closer with a class of planned amortization bonds or targeted amortization
    bonds.  The amortization schedule for these CMOs is structured so that, at
    specified prepayment rates within a range, their principal will be repaid
    at specified times and in specified amounts.  However, if any series of
    CMOs contains a class of planned amortization bonds or targeted
    amortization bonds, then the other classes in that series may not be
    retired in an order of priority determined strictly with reference to
    their maturity dates.  

              These other classes are often referred to as "support classes"
    because their function is to support the amortization schedule of the
    planned amortization bonds or targeted amortization bonds.  If the rate of
    prepayment on the underlying mortgages is faster than assumed, then
    classes with maturity dates later than the planned amortization bonds or
    targeted amortization bonds may be retired earlier than estimated to
    ensure that the planned amortization bonds or targeted amortization bonds
    receive the principal payments required by their amortization schedule. 
    Similarly, if the rate of prepayments is slower than anticipated, then
    earlier support classes may be retired later than estimated.  Hence,
    support classes of a series that contains planned amortization bonds or
    targeted amortization bonds have less predictable prepayment
    characteristics than classes of a series that does not.  This lack of
    predictability regarding prepayments also causes support class bonds to
    have greater market value fluctuation than other classes of a CMO.  (See
    "Description of Portfolio" for the number of planned amortization bonds,
    targeted amortization bonds or support class bonds in the Trust
    portfolio.)  The rate of prepayment on the underlying mortgages of a CMO
    will most likely decline as interest rates increase.  If the rate of
    prepayment declines, the weighted average life of the support class bonds
    will most likely increase and, in some cases, the decline will impact the
    yield and market value of these Securities.  This may cause an investor's
    principal in a support class bond to be outstanding for a longer period of
    time than initially anticipated.  Conversely, if interest rates decline,
    prepayments on the underlying mortgages will most likely increase, and the
    weighted average life of the support class bonds may be shorter than
    anticipated.  A holder of a support class bond in these situations may be
    unable to reinvest the proceeds of these principal distributions at an
    effective interest rate equal to the specified coupon rate on the original
    support class bond.  Therefore, an investor expecting to earn a fixed
    return for a fixed number of years may find the life of a support class
    investment decreases as interest rates fall and increases as they rise. 
    Investors should be aware that the Federal Financial Institutions
    Examination Council recently announced that certain high-risk CMO tranches
    are generally not suitable investments for depository institutions.  

              Some of the CMOs in the Trust may be either a class of
    Guaranteed REMIC Certificates ("REMIC Certificate") issued by FNMA or a
    class of REMIC Certificates issued by FHLMC.  A FNMA REMIC Certificate
    represents a beneficial ownership interest in a certain class of a FNMA
    REMIC Trust consisting of Fannie Maes, each of which in turn represents a
    beneficial interest in a pool of first lien, single-family, fixed-rate
    residential mortgage loans.  FNMA REMIC Certificates are issued pursuant
    to trust agreements executed by FNMA in both its corporate capacity and
    its capacity as trustee.  A FNMA REMIC Certificate evidences a beneficial
    ownership interest in the distribution of principal and interest on the
    underlying Fannie Maes, subject to certain limits and in an order of
    distribution established for the particular FNMA REMIC Trust.  Each FNMA
    REMIC Certificate is backed by the guaranty obligation of FNMA to
    distribute on a timely basis required installments of principal and
    interest and to distribute the principal balance of the FNMA REMIC
    Certificate in full no later than an established final distribution date,
    notwithstanding insufficiency of funds from the underlying Fannie Maes.  A
    FHLMC REMIC Certificate represents a beneficial ownership interest in a
    certain class of a pool of Freddie Macs, each of which in turn represents
    undivided interests in discrete pools of fixed-rate, first lien,
    residential mortgages or participations therein purchased by FHLMC.  FHLMC
    REMIC Certificates are issued pursuant to multiclass mortgage
    participation certificate agreements executed by FHLMC.  A FHLMC REMIC
    Certificate evidences a beneficial ownership interest in the distributions
    of principal and interest on the underlying Freddie Macs, subject to
    certain limits and in an order of distribution established for the
    particular FHLMC REMIC pool.  Each FHLMC REMIC Certificate is backed by
    the guaranty obligation of FHLMC to distribute required interest payments
    on a timely basis and to distribute required principal payments as
    principal payments on the underlying Freddie Macs are required to be made. 
    Except with respect to certain issues of "Gold" PCs, FHLMC generally does
    not guarantee timely payment of principal but does guarantee ultimate
    payment.  Both FNMA REMIC Certificates and FHLMC REMIC Certificates pay
    interest monthly.  (See "The Trusts--The Securities" in Part B of this
    Prospectus for a description of FHLMC Gold PCs.)

              If FNMA or FHLMC were unable to fulfill its guarantees,
    distributions to holders of REMIC Certificates such as the Trust would
    consist solely of payments and other recoveries upon the mortgages
    underlying the pledged Fannie Maes or Freddie Macs, respectively, and,
    accordingly, delinquencies and defaults would diminish distributions to
    the holders.  (See "Description of Portfolio" for the number of FNMA REMIC
    Certificates and FHLMC REMIC Certificates in the Trust portfolio.)

              Some of the CMOs in the Trust may be a class of compound
    interest bonds or principal only bonds.  Interest on compound interest
    bonds is accrued and is added to principal.  Such interest is not paid
    until all classes of CMOs issued in the same series with earlier final
    distributions dates are paid in full.  Principal only bonds entitle the
    holder to no payments of interest but the holder will receive cash flow
    from the amortization of principal and prepayments.  Both compound
    interest bonds and principal only bonds sell at a deep discount from par. 
    The Sponsors believe that a portfolio with a limited amount of compound
    interest bonds and principal only bonds will assist the Trust in achieving
    its objective of preserving capital.  Since the principal only bond will
    accrue to par if held to maturity, the holder of such a bond would receive
    a full return of his or her initial investment upon maturity of the bond. 
    In addition, compound interest bonds also assist in the preservation of
    capital as interest which accrues on these bonds is added to principal. 
    (See "Description of Portfolio" for the amount of Securities in the Trust
    that are a class of compound interest bonds or principal only bonds.)
        
              Special Risk Considerations.  An investment in Units of the
    Trust should be made with an understanding of risks which an investment in
    fixed rate CMOs may entail, including the risk that the value of the
    portfolio and, hence, the value of the Units will decline with increases
    in interest rates and that the life of the CMOs in the portfolio depends
    on the actual prepayments received on the underlying mortgage-backed
    securities, the timing of which cannot be determined but which may be
    sooner or later than anticipated, especially if interest rates decline. 
    The potential for appreciation, which could otherwise be expected to
    result from a decline in interest rates, may be limited by any increased
    prepayments by mortgagors.  Investors should also note that prepayments of
    principal on CMOs purchased at a premium over par will result in some loss
    on investment while prepayments on CMOs purchased at a discount from par
    will result in some gain on investment.  Also, if interest rates rise, the
    prepayment risk of higher yielding, premium CMOs and the prepayment
    benefit for lower yielding, discount CMOs will be reduced.  (See "The
    Trusts--Life of the Securities and of the Trusts" in Part B of this
    Prospectus.)  In addition, a number of factors, including the extent of
    prepayments of principal on the underlying mortgage-backed securities,
    affect the availability of funds for payment of principal of bonds on any
    payment date and, therefore, the timing of principal payments on each
    class of such bonds.
        
              While all of the mortgage-backed securities underlying each of
    the CMOs in the Trust are guaranteed as to the payment of principal and
    interest by GNMA, FNMA or FHLMC, the CMOs in the Trust represent
    obligations solely of the issuers of those CMOs and are not themselves
    insured or guaranteed by GNMA, FNMA or FHLMC, or any other governmental
    agency.  If a default were to occur with respect to any of the CMOs, there
    can be no assurance that the collateral securing such bonds would be
    sufficient to pay the principal and interest then due.

              CMOs are generally not listed on a national securities exchange
    or on the National Association of Securities Dealers Automated Quotation
    System, Inc.  Whether or not CMOs are listed on a national securities
    exchange, the principal trading market for the CMOs will generally be in
    the over-the-counter market.  As a result the existence of a liquid
    trading market for CMOs may depend on whether dealers will make a market
    in CMOs.  There can be no assurance that a market will be made for any of
    the CMOs in the Trust, that any market for the CMOs in the Trust portfolio
    will be maintained or of the liquidity of the CMOs in the Trust in any
    markets made.  The price at which the CMOs in the Trust may be sold to
    meet redemptions and the value of the Trust will be adversely affected if
    trading markets for the CMOs in the Trust are limited or absent.  (See
    "The Trust--Liquidity" in Part B of this Prospectus.)  In addition, the
    Trust may be restricted under the Investment Company Act of 1940 from
    selling securities to the Sponsors.  However, taking into account the
    foregoing and other factors, the Sponsors believe that the nature of the
    GNMA, FNMA or FHLMC guarantees of any securities that have been issued by
    them, respectively, and the nature of the Ginnie Maes, Fannie Maes or
    Freddie Macs securities payments of principal and interest due on the
    Securities make the Securities adequately marketable for purposes of
    redemptions of Units by the Trustee (see "Redemption" in Part B of this
    Prospectus).

              Investors should note that all of the CMOs in the Trust have
    been issued by trusts, corporations or other entities that have elected to
    be treated as Real Estate Mortgage Investment Conduits ("REMICs").  As
    such, Certificateholders will be required to include in income their
    respective pro rata share of interest on each Security (whether or not the
    Security has original issue discount) as interest accrues, whether or not
    the Certificateholder is an accrual method taxpayer.  (See "Tax Status" in
    Part B of this Prospectus.)

              The principal amount of Securities actually deposited in the
    Trust is affected by the prepayment estimate or factor for each CMO.  If
    the prepayment estimate or factor is adjusted because the level of actual
    prepayments increases with respect to a particular CMO prior to the
    settlement date of the Securities, the actual principal amount of
    Securities deposited in a Trust may be less than the amount noted above
    and the excess of any cash returned to the Trust as a result of these
    prepayments will be held in the Trust's principal account.  Cash balances
    maintained in the principal account do not generate income for the Trust.

              Educational material regarding CMOs is available upon request,
    from the Sponsor.

              PUBLIC OFFERING PRICE.  The secondary market Public Offering
    Price per 1,000 Units of the Trust is equal to the aggregate bid side
    evaluation of the underlying Securities in the Trust divided by the number
    of Units outstanding times 1,000, plus a sales charge of 3.5% of the
    Public Offering Price per 1,000 Units or 3.627% of the net amount invested
    in Securities per 1,000 Units.  In addition, accrued interest to the
    expected date of settlement is added to the Public Offering Price.  If the
    Units of the Trust had been purchased on the Evaluation Date, the Public
    Offering Price per 1,000 Units would have been $42.25, plus accrued
    interest of $.63, for a total of $42.88.  The Public Offering Price per
    1,000 Units may vary on a daily basis in accordance with the fluctuations
    in the aggregate bid price of the Bonds.  (See "Public Offering" in Part B
    of this Prospectus.)

              The figures above assume a purchase of 1,000 Units.  The price
    of a single Unit, or any multiple thereof, is calculated by dividing the
    secondary market Public Offering Price per 1,000 Units by 1,000 and
    multiplying by the number of Units.

              DISTRIBUTIONS.  Distributions of principal and interest income,
    less expenses, will be made by the Trust monthly on the 20th of each
    month.  (See "Rights of Certificateholders--Interest and Principal
    Distributions" in Part B of this Prospectus.  For the estimated amount of
    distributions see "Summary of Essential Information" for the Trust in this
    Part A.) 

              ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN. 
    Estimated Long Term Return for the Trust is calculated by:  (1) computing
    the yield to maturity for each CMO in the Trust's portfolio in accordance
    with accepted CMO practices, which practices take into account not only
    the interest payable on the CMO but also the amortization of premiums or
    accretion of discounts, if any, and estimates of projected prepayments;
    (2) calculating the average of the yields for the CMOs in the Trust's
    portfolio by weighing each CMO's yield by the market value of the CMO and
    by the amount of time remaining to the date to which the CMO 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 Certificateholders.  The resulting Estimated Long Term
    Return represents a measure of the return to Certificateholders earned
    over the estimated life of the Trust.  (For the Estimated Long Term Return
    to Certificateholders per 1,000 Units, see "Summary of Essential
    Information" for the Trust.) 

              Estimated Current Return for the Trust is calculated by dividing
    the Estimated Net Annual Interest Income per 1,000 Units by the Public
    Offering Price per 1,000 Units.  In contrast to the Estimated Long Term
    Return, the Estimated Current Return does not take into account estimates
    of prepayments or the amortization of premium or accretion of discount, if
    any, on the CMOs in the portfolio of the Trust.  On the Evaluation Date,
    the Estimated Net Annual Interest Income per 1,000 Units divided by the
    Public Offering Price per 1,000 Units resulted in the Estimated Current
    Return stated for the Trust under "Summary of Essential Information" in
    Part A.

              If the CMOs in the Trust are priced at a discount, the Estimated
    Current Return will generally be lower relative to the Estimated Long Term
    Return, whereas if the CMOs are priced at a premium, the Estimated Current
    Return will generally be higher relative to the Estimated Long Term
    Return.  This is because Estimated Current Return reflects primarily the
    interest rate on the CMOs, while Estimated Long Term Return reflects yield
    and timing of principal payments, and thus increases when the principal
    returned is greater than the price paid for the CMOs (discount) and
    decreases when the principal returned is lower than the price paid
    (premium).  Estimated Long Term Return is calculated using an estimated
    average life for the CMOs in the Trust.  Estimated average life is an
    essential factor in the calculation of Estimated Long Term Return.  When
    the Trust has a shorter average life than is estimated, Estimated Long
    Term Return will be higher if the Trust contains CMOs priced at a discount
    and lower if the CMOs are priced at a premium.  Conversely, when the Trust
    has a longer average life than is estimated, Estimated Long Term Return
    will be lower if the CMOs are priced at a discount and higher if the CMOs
    are priced at a premium.  To calculate estimated average life several
    assumptions are made to derive an estimated prepayment rate for the
    mortgages underlying the Ginnie Maes, Fannie Maes or Freddie Macs that may
    back the CMOs in the Portfolio; the calculation of estimated prepayment
    rates is based upon actual recent prepayments and analysis of several
    factors including, among other things, the spread between present market
    interest rates and the rate on the mortgages and the housing environment. 
    The estimated prepayment rate that is derived is then applied to retire
    the principal amount of each CMO class of the same series as each CMO in
    the Trust, including those CMOs in the Trust, according to the specific
    principal reduction schedule of each series.  For a more detailed
    explanation of the calculation of estimated average life, see "Estimated
    Long Term Return and Estimated Current Return" in Part B of this
    Prospectus.  The estimated average life for the Trust is subject to change
    with alterations in the data used in any of the underlying assumptions. 
    The actual average lives of the CMOs in the Trust portfolio and the actual
    long term returns will be different from the estimated average lives and
    the estimated long term returns.

              The Estimated Net Annual Interest Income per 1,000 Units 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, prepayment,
    maturity, sale or other disposition of the CMOs 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 CMOs.  Therefore, there is no
    assurance that the present Estimated Current Return or Estimated Long Term
    Return will be realized in the future.

              Market for Units.  The Sponsors, although not obligated to do
    so, intend to maintain a secondary market for the Units of the Trust.  The
    secondary market repurchase price will be based on the aggregate bid side
    evaluation of the Securities in the Trust; and the reoffer price will be
    based on the aggregate bid side evaluation of the Securities, divided by
    the number of Units outstanding times 1,000, plus a sales charge of 3.5%
    (3.627% of the net amount invested), plus net accrued interest.  If a
    market is not maintained a Certificateholder will be able to redeem his
    Units with the Trustee at a price based on the aggregate bid side
    evaluation of the Securities.  (See "Sponsor Repurchase" in Part B of this
    Prospectus.)

              Total Reinvestment Plan.  Distributions from the Trust are made
    to Certificateholders monthly.  The Certificateholder has the option,
    however, of either receiving his interest check, together with any
    principal payments, from the Trustee or participating in a reinvestment
    program offered by the Sponsors in shares of The Treasurer's Fund, Inc.,
    U.S. Treasury Money Market Portfolio (the "Fund").  Gabelli-O'Connor Fixed
    Income Mutual Funds Management Co. serves as the investment advisor of the
    Fund and GOC Fund Distributors, Inc. serves as distributor for the Fund. 
    Participation in the reinvestment option is conditioned on the Fund's
    lawful qualification for sale in the state in which the Certificateholder
    is a resident.  The Plan is not designed to be a complete investment
    program.  See "Total Reinvestment Plan" in Part B of this Prospectus.  The
    shares of the Fund are not rated by Standard & Poor's.

       +  Plus accrued interest.

      ++  The estimated current return and estimated long term return are
          increased for transactions entitled to a discount (see "Volume and
          Other Discounts" in Part B of this Prospectus). 

     +++  Based solely upon the bid side evaluation of the underlying
          Securities.  Upon tender for redemption, the price to be paid will
          be calculated as described under "Trustee Redemption" in Part B of
          this Prospectus. 

       #  See "Comparison of Public Offering Price, Sponsors' Repurchase Price
          and Redemption Price" in Part B of this Prospectus. 

     (1)  Estimated current return represents annual interest income after
          estimated annual expenses divided by the Public Offering Price,
          including a 3.5% maximum sales charge.  Estimated long term return
          is the net annual percentage return based on the yield on each
          underlying Security in the Trusts weighted to reflect market value
          and estimated average life.  The estimated weighted average life to
          maturity of the Trusts is an estimate based upon various assumptions
          discussed more fully under "Estimated Long Term Return and Estimated
          Current Return" in Part B of this Prospectus.  Estimated long term
          return is adjusted for estimated expenses and the maximum public
          offering price but not for delays in the Trust's distribution of
          income.  Estimated current return shows current annual cash return
          to investors while estimated long term return shows the return on
          Units held to estimated average life, reflecting prepayments of
          principal, maturities, discounts and premiums on underlying
          Securities.  Actual returns will vary with purchase price, payments
          and prepayments of principal on the underlying Ginnie Maes, Fannie
          Maes or Freddie Macs which back the Securities, and changes in Trust
          income after expenses.  These returns do not include the effects of
          any delay in payments to Unitholders and a calculation which
          includes those effects would be lower.  See "Estimated Long Term
          Return and Estimated Current Return" in Part B of this Prospectus.

                         INFORMATION REGARDING THE TRUSTS
                                AS OF JUNE 30, 1994


    Description of Portfolio*


          The Trust consists of 2 issues of CMOs.  The Sponsors have
    participated as a sole underwriter or manager, co-manager or member of an
    underwriting syndicate from which 25.3% of the initial aggregate principal
    amount of the CMOs in the Portfolio were acquired.  None of the CMOs have
    been issued by entities created by GNMA, 100% have been issued by entities
    created by FNMA, none have been issued by entities created by FHLMC and
    none have been issued by private issuers.  All of the CMOs in the Trust
    have been issued by trusts, corporations or other entities that have
    elected to be treated as Real Estate Mortgage Investment Conduits.  The
    CMOs in the Trust have stated final distribution dates ranging from
    June 25, 2012 through April 25, 2018 and had estimated average lives
    (based upon estimated prepayment rates at the initial date of deposit)
    ranging from 7.8 to 8 years.

          All $898,722 of the principal amount of the Securities in the Trust
    are planned amortization bonds or targeted amortization bonds.  None of
    the principal amount of the Securities are support class bonds that are
    part of a series that contains planned amortization bonds or targeted
    amortization bonds.  All of the principal amount of the Securities in the
    Trust are FNMA REMIC Certificates.  None of the principal amount of the
    Securities in the Trust are a class of compound interest bonds or
    principal only bonds.  The Bonds may also be subject to other calls, which
    may be permitted or required by events which cannot be predicted (such as
    destruction, condemnation, termination of a contract, or receipt of excess
    or unanticipated revenues).

          As of June 30, 1994, 100% of the aggregate principal amount of the
    Securities in the Trust were acquired at a discount from par, none of the
    Securities in the Trust were acquired at a premium and none were acquired
    at par.  A Certificateholder may receive more or less than his original
    purchase price upon disposition of his Units because the value of the
    Units fluctuates with the value of the underlying Securities. 


        
    *     Changes in the Trust Portfolio:  From July 1, 1994 to September 23,
          1994, there has been a paydown on the securities in portfolio nos. 1
          and 2 and $257,919.40 and $219,315.32 of the principal amounts of
          the securities, respectively, are no longer contained in the Trust. 
          354,945 Units have been redeemed from the Trust.

MORTGAGE SECURITIES TRUST, CMO SERIES 1

Notes to Financial Statements

June 30, 1994, 1993, and 1992





(1)
Organization and Financial and Statistical Information

Mortgage Securities Trust, CMO Series 1 (Trust) was organized on
November 1, 1990 (date of deposit) by Bear, Stearns & Co. Inc. and
Gruntal & Co., Incorporated (Co-Sponsors) 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

United States Trust Company 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
Standard & Poor's Corporation (Evaluator).  The market value of the
investments is based upon the bid prices for the securities at the end
of the period, except that the market value on the date of deposit
represents the cost to the 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
on a monthly basis.

The Trust Indenture and Agreement further requires that principal
received from the disposition of securities, other than those securities
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 periods ended
June 30, 1994, 1993 and 1992.

The Trust Indenture and Agreement also requires the Trust to redeem
units tendered.  2,777,715 units and 623,381 units were redeemed
during the years ending June 30, 1994 and 1993, respectively.  No units
were redeemed during the year ended June 30, 1992.

(5)
Net Assets

At June 30, 1994, the net assets of the Trust represented the interest
of Certificateholders as follows:


Original cost to Certificateholders                 $  25,573,999

Less initial gross underwriting commission              ( 895,090)

                                                       24,678,909


Cost of securities sold or called                     (23,796,046)

              The Trust is a unit investment trust designated Mortgage Series
    Trust, CMO Series 6 Intermediate Portfolio (the "Trust").  The Trust
    consists of an underlying portfolio of collateralized mortgage obligations
    ("CMOs" or "Securities") and was formed to obtain safety of capital and
    provide a high level of current distributions of interest income.  The
    Trust seeks to obtain a higher yield than fixed income investments with
    comparable AAA ratings.  An investment in the Trust entails differing
    degrees of risk.  The Trust seeks to achieve its objective through
    investment in a fixed portfolio of CMOs which may have been issued as debt
    obligations of a trust or corporation or which may represent certificated
    interests of beneficial ownership in pools of mortgage-backed securities. 
    All of the CMOs in the portfolio are backed by underlying mortgage-backed
    securities which are pledged as collateral to secure payment of principal
    and interest on the CMOs.  Each of these underlying mortgage-backed
    securities is guaranteed as to the payment of principal and interest by
    the Government National Mortgage Association ("GNMA"), the Federal
    National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
    Corporation ("FHLMC").  All of the CMOs in the Trust are issued by GNMA,
    FNMA or FHLMC or are otherwise rated AAA by Standard & Poor's and,
    therefore, the Units of the Trust are rated AAA by Standard & Poor's
    Corporation.  The Units of the Trust are not, however, guaranteed by GNMA,
    FNMA, FHLMC, the United States or any of its agencies.  The full faith and
    credit of the United States is pledged to the payment of all amounts
    guaranteed by GNMA.  However, payments guaranteed by FNMA and FHLMC are
    not guaranteed by the United States and neither the CMOs in the Trust nor
    any underlying Fannie Maes or Freddie Macs constitute a debt obligation of
    the United States or any of its agencies.  The Sponsors are Bear, Stearns
    & Co. and Gruntal & Co., Incorporated.  The value of the Units will
    fluctuate with the value of the CMOs in the portfolio.  Both the Estimated
    Current Return and the Estimated Long Term Return are subject to
    fluctuations with changes in portfolio composition, principal payments and
    prepayments, changes in the market value of the CMOs in the portfolio and
    changes in fees and expenses.  Minimum purchase:  1,000 Units.

              THE TRUST.  The Trust is a unit investment trust designated
    Mortgage Securities Trust, CMO Series 6 Intermediate Portfolio
    ("Intermediate Portfolio").  The Trust was formed to obtain safety of
    capital and a high level of current distributions of interest income
    through investment in a fixed portfolio of CMOs.  A CMO is a multiclass
    bond backed by a pool of mortgage pass-through securities or mortgage
    loans.  CMOs are also known as "real estate mortgage investment conduits"
    (REMICs).  As a result of the 1986 Tax Reform Act, most CMOs are issued in
    REMIC form to create a certain tax advantage for the issuer.  The terms
    CMO and REMIC are used interchangeably.  The Trust seeks to obtain a
    higher yield than fixed income investments with comparable AAA ratings. 
    An investment in the Trust entails differing degrees of risk.

              The Intermediate Portfolio will invest primarily in planned
    amortization or target amortization classes of CMOs.  Such classes of CMOs
    receive payments of principal according to a planned schedule to the
    extent that prepayments on the underlying mortgage-backed securities occur
    within a broad time period.  The principal is reduced only in specified
    amounts at specified times resulting in greater predictability of
    principal payments for the planned amortization bonds or targeted
    amortization bonds.  For a discussion on planned amortization bonds or
    targeted amortization bonds see "The Trusts--The Securities--Planned
    Amortization or Targeted Amortization Bonds and Support Bonds" in Part B
    of this Prospectus.  The Intermediate Portfolio may also invest in other
    types of CMOs described above and in "The Trusts--The Securities" in
    Part B of this Prospectus. 

              All of the CMOs in the Trust are backed by underlying mortgage-
    backed securities which are pledged as collateral to secure payment of
    principal and interest on the CMOs.  Each of these mortgage-backed
    securities is guaranteed as to the payment of principal and interest by
    either the Government National Mortgage Association ("GNMA"), the Federal
    National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
    Corporation ("FHLMC").  All of the CMOs in the Trust are issued by GNMA,
    FNMA or FHLMC or are otherwise rated AAA by Standard & Poor's Corporation
    ("Standard & Poor's") and therefore, the Units of the Trust are rated AAA
    by Standard & Poor's.  There can be no assurance that the Trust's
    investment objectives can be achieved.  Investment in the Trust should be
    made with an understanding of the risks inherent in an investment in CMOs. 
    (See "The Trust--Special Risk Considerations" in this Part A.)  Each Unit
    of the Trust represents an undivided interest in the principal and net
    income of the Trust in the ratio of one thousand Units for the indicated
    principal amount of Securities in the Trust.  (See "The Trust--
    Organization" in Part B of this Prospectus.)  (For the specific number of
    Units in the Trust, see "Summary of Essential Information" in this
    Part A.)

              Generally, CMOs are designed to provide a substantial degree of
    prepayment and reinvestment risk protection as compared to other mortgage
    related securities.  The CMOs may have been issued as debt obligations of
    a trust or corporation or as certificated interests representing
    beneficial ownership in a pool of mortgage-backed securities (See "The
    Trusts--The Securities" in Part B of this Prospectus for further
    description and examples) which trust, corporation or pool may have been
    established for the sole purpose of issuing CMOs by any of GNMA, FNMA or
    FHLMC or by a private business organization.  Such private business
    organizations are typically single-purpose corporations established by
    mortgage-banking institutions for the sole purpose of issuing CMOs.  Any
    CMOs in the Trust that have been issued by private business organizations
    have been rated AAA by Standard & Poor's.  The sole assets of the issuers
    of the CMOs are the underlying mortgage-backed securities.  If the
    collateral securing the Securities of these issuers is insufficient to
    make payments on those Securities, it is unlikely that any other assets of
    these issuers will be available for payment of the deficiency.  The
    underlying mortgage-backed securities which are pledged as collateral to
    secure the payment of principal and interest on the CMOs may be (i) "fully
    modified pass-through" mortgage-backed certificates, guaranteed by GNMA
    ("Ginnie Maes"), (ii) mortgage pass-through certificates guaranteed by
    FNMA ("Fannie Maes") or (iii) mortgage participation certificates
    guaranteed by FHLMC ("Freddie Macs").  The full faith and credit of the
    United States is pledged to the payment of all amounts guaranteed by GNMA. 
    However, payments guaranteed by FNMA and FHLMC are not guaranteed by the
    United States and neither the CMOs in the Trust nor any underlying Fannie
    Maes or Freddie Macs constitute a debt or obligation of the United States
    or any of its agencies.  The Units of the Trust, as such, are not
    guaranteed by any of GNMA, FNMA, FHLMC, the United States or any of its
    agencies.  Additionally, CMOs that are issued by GNMA, FNMA or FHLMC or by
    any entity established by GNMA, FNMA or FHLMC are guaranteed as to payment
    of principal and interest by GNMA, FNMA or FHLMC, respectively.  The
    guaranty obligations of GNMA with respect to any Ginnie Maes or any CMOs
    are supported by the full faith and credit of the United States.  However,
    the guaranty of obligations of FNMA and FHLMC with respect to any Fannie
    Maes or Freddie Macs or any CMOs are obligations of FNMA and FHLMC only
    (limited by their respective credit capabilities) and are not supported by
    the full faith and credit of the United States or any other governmental
    entity.

              CMO Structure.  CMOs are generally issued as a series of
    different classes.  An issue of CMOs generally is backed by a larger
    number of mortgages than a pool of Ginnie Maes, Fannie Maes or Freddie
    Macs, thus allowing greater statistical prediction of prepayment
    characteristics.  Interest and principal payments on the mortgages
    underlying any series will first be applied to meet the interest payment
    requirements of each class in the series other than any class in respect
    of which interest accrues but is not paid or any "principal only" class. 
    Principal payments on the underlying mortgages are thereafter generally
    applied to pay the principal amount of the class that has the earliest
    maturity date.  Once that class is retired, the principal payments on the
    underlying mortgages are applied to the class with the next earliest
    maturity date.  This is repeated until all classes are paid.  Therefore,
    while each class of CMOs remains subject to prepayment as the underlying
    mortgages prepay, structuring several classes of CMOs in the stream of
    principal payments allows a more predictable estimate of the period of
    time when any one class is likely to be repaid.  The estimate can be even
    closer with a class of planned amortization bonds or targeted amortization
    bonds.  The amortization schedule for these CMOs is structured so that, at
    specified prepayment rates within a range, their principal will be repaid
    at specified times and in specified amounts.  However, if any series of
    CMOs contains a class of planned amortization bonds or targeted
    amortization bonds, then the other classes in that series may not be
    retired in an order of priority determined strictly with reference to
    their maturity dates.  

              These other classes are often referred to as "support classes"
    because their function is to support the amortization schedule of the
    planned amortization bonds or targeted amortization bonds.  If the rate of
    prepayment on the underlying mortgages is faster than assumed, then
    classes with maturity dates later than the planned amortization bonds or
    targeted amortization bonds may be retired earlier than estimated to
    ensure that the planned amortization bonds or targeted amortization bonds
    receive the principal payments required by their amortization schedule. 
    Similarly, if the rate of prepayments is slower than anticipated, then
    earlier support classes may be retired later than estimated.  Hence,
    support classes of a series that contains planned amortization bonds or
    targeted amortization bonds have less predictable prepayment
    characteristics than classes of a series that does not.  This lack of
    predictability regarding prepayments also causes support class bonds to
    have greater market value fluctuation than other classes of a CMO.  (See
    "Description of Portfolios" for the number of planned amortization bonds,
    targeted amortization bonds or support class bonds in the Trust
    portfolios.)  The rate of prepayment on the underlying mortgages of a CMO
    will most likely decline as interest rates increase.  If the rate of
    prepayment declines, the weighted average life of the support class bonds
    will most likely increase and, in some cases, the decline will impact the
    yield and market value of these Securities.  This may cause an investor's
    principal in a support class bond to be outstanding for a longer period of
    time than initially anticipated.  Conversely, if interest rates decline,
    prepayments on the underlying mortgages will most likely increase, and the
    weighted average life of the support class bonds may be shorter than
    anticipated.  A holder of a support class bond in these situations may be
    unable to reinvest the proceeds of these principal distributions at an
    effective interest rate equal to the specified coupon rate on the original
    support class bond.  Therefore, an investor expecting to earn a fixed
    return for a fixed number of years may find the life of a support class
    investment decreases as interest rates fall and increases as they rise. 
    Investors should be aware that the Federal Financial Institutions
    Examination Council has stated that certain high-risk CMO tranches are
    generally not suitable investments for depository institutions.

              Some of the CMOs in the Trust may be either a class of
    Guaranteed REMIC Certificates ("REMIC Certificate") issued by FNMA or a
    class of REMIC Certificates issued by FHLMC.  A FNMA REMIC Certificate
    represents a beneficial ownership interest in a certain class of a FNMA
    REMIC Trust consisting of Fannie Maes, each of which in turn represents a
    beneficial interest in a pool of first lien, single-family, fixed-rate
    residential mortgage loans.  FNMA REMIC Certificates are issued pursuant
    to trust agreements executed by FNMA in both its corporate capacity and
    its capacity as trustee.  A FNMA REMIC Certificate evidences a beneficial
    ownership interest in the distribution of principal and interest on the
    underlying Fannie Maes, subject to certain limits and in an order of
    distribution established for the particular FNMA REMIC Trust.  Each FNMA
    REMIC Certificate is backed by the guaranty obligation of FNMA to
    distribute on a timely basis required installments of principal and
    interest and to distribute the principal balance of the FNMA REMIC
    Certificate in full no later than an established final distribution date,
    notwithstanding insufficiency of funds from the underlying Fannie Maes.  A
    FHLMC REMIC Certificate represents a beneficial ownership interest in a
    certain class of a pool of Freddie Macs, each of which in turn represents
    undivided interests in discrete pools of fixed-rate, first lien,
    residential mortgages or participations therein purchased by FHLMC.  FHLMC
    REMIC Certificates are issued pursuant to multiclass mortgage
    participation certificate agreements executed by FHLMC.  A FHLMC REMIC
    Certificate evidences a beneficial ownership interest in the distributions
    of principal and interest on the underlying Freddie Macs, subject to
    certain limits and in an order of distribution established for the
    particular FHLMC REMIC pool.  Each FHLMC REMIC Certificate is backed by
    the guaranty obligation of FHLMC to distribute required interest payments
    on a timely basis and to distribute required principal payments as
    principal payments on the underlying Freddie Macs are required to be made. 
    Except with respect to certain issues of "Gold" PCs, FHLMC generally does
    not guarantee timely payment of principal but does guarantee ultimate
    payment.  Both FNMA REMIC Certificates and FHLMC REMIC Certificates pay
    interest monthly.  (See "The Trusts--The Securities" in Part B of this
    Prospectus for a description of FHLMC Gold PCs.)

              If FNMA or FHLMC were unable to fulfill its guarantees,
    distributions to holders of REMIC Certificates such as the Trust would
    consist solely of payments and other recoveries upon the mortgages
    underlying the pledged Fannie Maes or Freddie Macs, respectively, and,
    accordingly, delinquencies and defaults would diminish distributions to
    the holders.  (See "Description of Portfolios" for the number of FNMA
    REMIC Certificates and FHLMC REMIC Certificates in the Trust portfolio.)

              Some of the CMOs in the Trust may be a class of compound
    interest bonds or principal only bonds.  Interest on compound interest
    bonds is accrued and is added to principal.  Such interest is not paid
    until all classes of CMOs issued in the same series with earlier final
    distributions dates are paid in full.  Principal only bonds entitle the
    holder to no payments of interest but the holder will receive cash flow
    from the amortization of principal and prepayments.  Both compound
    interest bonds and principal only bonds sell at a deep discount from par. 
    The Sponsors believe that a portfolio with a limited amount of compound
    interest bonds and principal only bonds will assist the Trusts in
    achieving their objective of preserving capital.  Since the principal only
    bond will accrue to par if held to maturity, the holder of such a bond
    would receive a full return of his or her initial investment upon maturity
    of the bond.  In addition, compound interest bonds also assist in the
    preservation of capital as interest which accrues on these bonds is added
    to principal.  (See "Description of Portfolio" for the amount of
    Securities in the Trust that are a class of compound interest bonds or
    principal only bonds.)

              Special Risk Considerations.  An investment in Units of the
    Trust should be made with an understanding of risks which an investment in
    fixed rate CMOs may entail, including the risk that the value of the
    portfolio and, hence, the value of the Units will decline with increases
    in interest rates and that the life of the CMOs in the portfolio depends
    on the actual prepayments received on the underlying mortgage-backed
    securities, the timing of which cannot be determined but which may be
    sooner or later than anticipated, especially if interest rates decline. 
    The potential for appreciation, which could otherwise be expected to
    result from a decline in interest rates, may be limited by any increased
    prepayments by mortgagors.  Investors should also note that prepayments of
    principal on CMOs purchased at a premium over par will result in some loss
    on investment while prepayments on CMOs purchased at a discount from par
    will result in some gain on investment.  Also, if interest rates rise, the
    prepayment risk of higher yielding, premium CMOs and the prepayment
    benefit for lower yielding, discount CMOs will be reduced.  (See "The
    Trusts--Life of the Securities and of the Trusts" in Part B of this
    Prospectus.)  In addition, a number of factors, including the extent of
    prepayments of principal on the underlying mortgage-backed securities,
    affect the availability of funds for payment of principal of bonds on any
    payment date and, therefore, the timing of principal payments on each
    class of such bonds.

              While all of the mortgage-backed securities underlying each of
    the CMOs in the Trust are guaranteed as to the payment of principal and
    interest by GNMA, FNMA or FHLMC, the CMOs in the Trust represent
    obligations solely of the issuers of those CMOs and are not themselves
    insured or guaranteed by GNMA, FNMA or FHLMC, or any other governmental
    agency.  If a default were to occur with respect to any of the CMOs, there
    can be no assurance that the collateral securing such bonds would be
    sufficient to pay the principal and interest then due.

              CMOs are generally not listed on a national securities exchange
    or on the National Association of Securities Dealers Automated Quotation
    System, Inc.  Whether or not CMOs are listed on a national securities
    exchange, the principal trading market for the CMOs will generally be in
    the over-the-counter market.  As a result the existence of a liquid
    trading market for CMOs may depend on whether dealers will make a market
    in CMOs.  There can be no assurance that a market will be made for any of
    the CMOs in the Trust, that any market for the CMOs in the Trust's
    portfolio will be maintained or of the liquidity of the CMOs in the Trust
    in any markets made.  The price at which the CMOs in the Trust may be sold
    to meet redemptions and the value of the Trust will be adversely affected
    if trading markets for the CMOs in the Trust are limited or absent.  (See
    "The Trust--Liquidity" in Part B of this Prospectus.)  In addition, the
    Trust may be restricted under the Investment Company Act of 1940 from
    selling securities to the Sponsors.  However, taking into account the
    foregoing and other factors, the Sponsors believe that the nature of the
    GNMA, FNMA or FHLMC guarantees of any securities that have been issued by
    them, respectively, and the nature of the Ginnie Maes, Fannie Maes or
    Freddie Macs securities payments of principal and interest due on the
    Securities make the Securities adequately marketable for purposes of
    redemptions of Units by the Trustee (see "Redemption" in Part B of this
    Prospectus).

              Investors should note that all of the CMOs in the Trust have
    been issued by trusts, corporations or other entities that have elected to
    be treated as Real Estate Mortgage Investment Conduits ("REMICs").  As
    such, Certificateholders will be required to include in income their
    respective pro rata share of interest on each Security (whether or not the
    Security has original issue discount) as interest accrues, whether or not
    the Certificateholder is an accrual method taxpayer.  (See "Tax Status" in
    Part B of this Prospectus.)

              The principal amount of Securities actually deposited in the
    Trust is affected by the prepayment estimate or factor for each CMO.  If
    the prepayment estimate or factor is adjusted because the level of actual
    prepayments increases with respect to a particular CMO prior to the
    settlement date of the Securities, the actual principal amount of
    Securities deposited in the Trust may be less than the amount noted above
    and the excess of any cash returned to the Trust as a result of these
    prepayments will be held in the Trust's principal account.  Cash balances
    maintained in the principal account do not generate income for the Trust.

              Educational material regarding CMOs is available upon request,
    from the Sponsor.

              PUBLIC OFFERING PRICE.  The secondary market Public Offering
    Price per 1,000 Units of the Trust is equal to the aggregate bid side
    evaluation of the underlying Securities in a Trust divided by the number
    of Units outstanding times 1,000, plus a sales charge of 3.75% of the
    Public Offering Price per 1,000 Units or 3.896% of the net amount invested
    in Securities per 1,000 Units of the Intermediate Portfolio.  In addition,
    accrued interest to the expected date of settlement is added to the Public
    Offering Price.  If the Units of the Intermediate Portfolio had been
    purchased on the Evaluation Date, the Public Offering Price per 1,000
    Units would have been $172.46, plus accrued interest of $.71, for a total
    of $173.17.  The Public Offering Price per 1,000 Units may vary on a daily
    basis in accordance with the fluctuations in the aggregate bid price of
    the Bonds.  (See "Public Offering" in Part B of this Prospectus.)

              The figures above assume a purchase of 1,000 Units.  The price
    of a single Unit, or any multiple thereof, is calculated by dividing the
    Secondary Market Public Offering Price per 1,000 Units by 1,000 and
    multiplying by the number of Units.

              DISTRIBUTIONS.  Distributions of principal and interest income,
    less expenses, will be made by the Trust monthly on the 20th of each
    month.  (See "Rights of Certificateholders--Interest and Principal
    Distributions" in Part B of this Prospectus.  For the estimated amount of
    distributions see "Summary of Essential Information" for the Trust in this
    Part A.) 

              ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN. 
    Estimated Long Term Return for the Trust is calculated by:  (1) computing
    the yield to maturity for each CMO in the Trust's portfolio in accordance
    with accepted CMO practices, which practices take into account not only
    the interest payable on the CMO but also the amortization of premiums or
    accretion of discounts, if any, and estimates of projected prepayments;
    (2) calculating the average of the yields for the CMOs in the Trust's
    portfolio by weighing each CMO's yield by the market value of the CMO and
    by the amount of time remaining to the date to which the CMO 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 Certificateholders.  The resulting Estimated Long Term
    Return represents a measure of the return to Certificateholders earned
    over the estimated life of the Trust.  (For the Estimated Long Term Return
    to Certificateholders per 1,000 Units, see "Summary of Essential
    Information" for each Trust.) 

              Estimated Current Return for the Trust is calculated by dividing
    the Estimated Net Annual Interest Income per 1,000 Units by the Public
    Offering Price per 1,000 Units.  In contrast to the Estimated Long Term
    Return, the Estimated Current Return does not take into account estimates
    of prepayments or the amortization of premium or accretion of discount, if
    any, on the CMOs in the portfolio of the Trust.  On the Evaluation Date,
    the Estimated Net Annual Interest Income per 1,000 Units divided by the
    Public Offering Price per 1,000 Units resulted in the Estimated Current
    Return stated for the Trust under "Summary of Essential Information" in
    Part A.

              If the CMOs in the Trust are priced at a discount, the Estimated
    Current Return will generally be lower relative to the Estimated Long Term
    Return, whereas if the CMOs are priced at a premium, the Estimated Current
    Return will generally be higher relative to the Estimated Long Term
    Return.  This is because Estimated Current Return reflects primarily the
    interest rate on the CMOs, while Estimated Long Term Return reflects yield
    and timing of principal payments, and thus increases when the principal
    returned is greater than the price paid for the CMOs (discount) and
    decreases when the principal returned is lower than the price paid
    (premium).  Estimated Long Term Return is calculated using an estimated
    average life for the CMOs in the Trust.  Estimated average life is an
    essential factor in the calculation of Estimated Long Term Return.  When a
    particular Trust has a shorter average life than is estimated, Estimated
    Long Term Return will be higher if the Trust contains CMOs priced at a
    discount and lower if the CMOs are priced at a premium.  Conversely, when
    a particular Trust has a longer average life than is estimated, Estimated
    Long Term Return will be lower if the CMOs are priced at a discount and
    higher if the CMOs are priced at a premium.  To calculate estimated
    average life several assumptions are made to derive an estimated
    prepayment rate for the mortgages underlying the Ginnie Maes, Fannie Maes
    or Freddie Macs that may back the CMOs in the Portfolio; the calculation
    of estimated prepayment rates is based upon actual recent prepayments and
    analysis of several factors including, among other things, the spread
    between present market interest rates and the rate on the mortgages and
    the housing environment.  The estimated prepayment rate that is derived is
    then applied to retire the principal amount of each CMO class of the same
    series as each CMO in the Trust, including those CMOs in the Trust,
    according to the specific principal reduction schedule of each series. 
    For a more detailed explanation of the calculation of estimated average
    life, see "Estimated Long Term Return and Estimated Current Return" in
    Part B of this Prospectus.  The estimated average life for the Trust is
    subject to change with alterations in the data used in any of the
    underlying assumptions.  The actual average lives of the CMOs in the Trust
    portfolios and the actual long term returns will be different from the
    estimated average lives and the estimated long term returns.

              The Estimated Net Annual Interest Income per 1,000 Units 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, prepayment,
    maturity, sale or other disposition of the CMOs 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 CMOs.  Therefore, there is no
    assurance that the present Estimated Current Return or Estimated Long Term
    Return will be realized in the future.

              Market for Units.  The Sponsors, although not obligated to do
    so, intend to maintain a secondary market for the Units of the Trust.  The
    secondary market repurchase price will be based on the aggregate bid side
    evaluation of the Securities in the Trust; and the reoffer price will be
    based on the aggregate bid side evaluation of the Securities, divided by
    the number of Units outstanding times 1,000, plus a sales charge of 3.75%
    (3.896% of the net amount invested), plus net accrued interest for the
    Intermediate Portfolio.  If a market is not maintained a Certificateholder
    will be able to redeem his Units with the Trustee at a price based on the
    aggregate bid side evaluation of the Securities.  (See "Sponsor
    Repurchase" in Part B of this Prospectus.)

              Total Reinvestment Plan.  Distributions from the Trusts are made
    to Certificateholders monthly.  The Certificateholder has the option,
    however, of either receiving his interest check, together with any
    principal payments, from the Trustee or participating in a reinvestment
    program offered by the Sponsors in shares of The Treasurer's Fund, Inc.,
    U.S. Treasury Money Market Portfolio (the "Fund").  Gabelli-O'Connor Fixed
    Income Mutual Funds Management Co. serves as the investment advisor of the
    Fund and GOC Fund Distributors, Inc. serves as distributor for the Fund. 
    Participation in the reinvestment option is conditioned on the Fund's
    lawful qualification for sale in the state in which the Certificateholder
    is a resident.  The Plan is not designed to be a complete investment
    program.  See "Total Reinvestment Plan" in Part B of this Prospectus.  The
    shares of the Fund are not rated by Standard & Poor's.

     (1)  Estimated current return represents annual interest income after
          estimated annual expenses divided by the Public Offering Price,
          including for the Intermediate Portfolio, a 3.75% maximum sales
          charge.  Estimated long term return is the net annual percentage
          return based on the yield on each underlying Security in the Trust
          weighted to reflect market value and estimated average life.  The
          estimated weighted average life to maturity of the Trust is an
          estimate based upon various assumptions discussed more fully under
          "Estimated Long Term Return and Estimated Current Return" in Part B
          of this Prospectus.  Estimated long term return is adjusted for
          estimated expenses and the maximum public offering price but not for
          delays in the Trust's distribution of income.  Estimated current
          return shows current annual cash return to investors while estimated
          long term return shows the return on Units held to estimated average
          life, reflecting prepayments of principal, maturities, discounts and
          premiums on underlying Securities.  Actual returns will vary with
          purchase price, payments and prepayments of principal on the
          underlying Ginnie Maes, Fannie Maes or Freddie Macs which back the
          Securities, and changes in Trust income after expenses.  These
          returns do not include the effects of any delay in payments to
          Unitholders and a calculation which includes those effects would be
          lower.  See "Estimated Long Term Return and Estimated Current
          Return" in Part B of this Prospectus.

                          INFORMATION REGARDING THE TRUST
                                AS OF JUNE 30, 1994


    Description of Portfolio*

              The Trust consists of 3 issues of CMOs.  The Sponsors have not
    participated as a sole underwriter or manager, co-manager or member of an
    underwriting syndicate from which any of the initial aggregate principal
    amount of the CMOs in the Portfolio were acquired.  None of the CMOs have
    been issued by entities created by GNMA, 15.7% have been issued by
    entities created by FNMA, 84.3% have been issued by entities created by
    FHLMC and none have been issued by private issuers.  All of the CMOs in
    the Trust have been issued by trusts, corporations or other entities that
    have elected to be treated as Real Estate Mortgage Investment Conduits. 
    The CMOs in the Trust have stated final distribution dates ranging from
    April 15, 2019 through September 25, 2020 and had estimated average lives
    (based upon estimated prepayment rates at the initial date of deposit)
    ranging from 9.60 to 11.18 years.

              The CMO in Portfolio No. 2 (representing $371,501 of the
    principal amount of the Securities in the Trust) is a planned amortization
    bond or targeted amortization bond.  None of the principal amount of the
    Securities are support class bonds that are part of a series that contains
    planned amortization bonds or targeted amortization bonds.  As of June 30,
    1994, $371,501 of the principal amount of the Securities in the Trust are
    FNMA REMIC Certificates.  None of the principal amount of the Securities
    in the Trust are a class of compound interest bonds or principal only
    bonds.  The Bonds may also be subject to other calls, which may be
    permitted or required by events which cannot be predicted (such as
    destruction, condemnation, termination of a contract, or receipt of excess
    or unanticipated revenues).

    *     Changes in the Trust Portfolio:  From July 1, 1994 to September 23,
          1994, there has been a paydown on the securities in portfolio
          nos. 1, 2, and 3 and $79,720.94, $17,850.60 and $154,572 of the
          principal amount of the securities, respectively, are no longer
          contained in the Trust.  180,993 Units have been redeemed from the
          Trust.


              As of June 30, 1994, 38.4% of the aggregate principal amount of
    the Securities in the Trust were acquired at a discount from par, 61.6% of
    the Securities in the Trust were acquired at a premium and none were
    acquired at par.  A Certificateholder may receive more or less than his
    original purchase price upon disposition of his Units because the value of
    the Units fluctuates with the value of the underlying Securities.

MORTGAGE SECURITIES TRUST, CMO SERIES 6 INTERMEDIATE

Notes to Financial Statements

June 30, 1994, 1993 and 1992



(1)    Organization and Financial and Statistical Information

Mortgage Securities Trust, CMO Series 6 Intermediate (Trust) was
organized on October 17, 1991 (date of deposit) by Bear, Stearns & Co.
Inc. and Gruntal & Co., Incorporated (Co-Sponsors) 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

United States Trust Company 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
Standard & Poor's Corporation (Evaluator).  The market value of the
investments is based upon the bid prices for the securities at the end
of the period, except that the market value on the date of deposit
represents the cost to the 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
on a monthly basis.

The Trust Indenture and Agreement further requires that principal
received from the disposition of securities, other than those securities
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
two years period ended June 30, 1994, and for the period October 17,
1991 to June 30, 1992.

The Trust Indenture and Agreement also requires the Trust to redeem
units tendered.  190,620 and 217,232 units were redeemed during the
year ended June 30, 1994 and 1993, respectively. No units were redeemed
in the period ended June 30, 1992.

(5)    Net Assets

At June 30, 1994, the net assets of the Trust represented the interest
of Certificateholders as follows:

      Original cost to Certificateholders                $   6,235,104
      Less initial gross underwriting commission              (233,817)

                                                             6,001,287
      Accumulated cost of securities
          sold or called                                    (5,058,878)
      Net unrealized appreciation                               24,866
      Undistributed net investment income                        4,280
      Undistributed proceeds from securities
          sold or called                                       172,493

          Total                                          $   1,144,048

The original cost to Certificateholders, less the initial gross

    __________________________________________________________________

              The Trust is a unit investment trust designated Mortgage Series
    Trust, CMO Series 7 Short-Intermediate Portfolio (the "Trust").  The Trust
    consists of an underlying portfolio of collateralized mortgage obligations
    ("CMOs" or "Securities") and was formed to obtain safety of capital and
    provide a high level of current distributions of interest income.  The
    Trust seeks to obtain a higher yield than fixed income investments with
    comparable AAA ratings.  The Trust seeks to achieve its objectives through
    investment in a fixed portfolio of CMOs which may have been issued as debt
    obligations of a trust or corporation or which may represent certificated
    interests of beneficial ownership in pools of mortgage-backed securities. 
    All of the CMOs in the portfolio are backed by underlying mortgage-backed
    securities which are pledged as collateral to secure payment of principal
    and interest on the CMOs.  Each of these underlying mortgage-backed
    securities is guaranteed as to the payment of principal and interest by
    the Government National Mortgage Association ("GNMA"), the Federal
    National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
    Corporation ("FHLMC").  All of the CMOs in the Trust are issued by GNMA,
    FNMA or FHLMC or are otherwise rated AAA by Standard & Poor's and,
    therefore, the Units of the Trust are rated AAA by Standard & Poor's
    Corporation.  The Units of the Trust are not, however, guaranteed by GNMA,
    FNMA, FHLMC, the United States or any of its agencies.  The full faith and
    credit of the United States is pledged to the payment of all amounts
    guaranteed by GNMA.  However, payments guaranteed by FNMA and FHLMC are
    not guaranteed by the United States and neither the CMOs in the Trust nor
    any underlying Fannie Maes or Freddie Macs constitute a debt obligation of
    the United States or any of its agencies.  The Sponsors are Bear, Stearns
    & Co. and Gruntal & Co., Incorporated.  The value of the Units will
    fluctuate with the value of the CMOs in the portfolio.  Both the Estimated
    Current Return and the Estimated Long Term Return are subject to
    fluctuations with changes in portfolio composition, principal payments and
    prepayments, changes in the market value of the CMOs in the portfolios and
    changes in fees and expenses.  Minimum purchase:  1,000 Units.

              THE TRUST.  The Trust is a unit investment trust designated
    Mortgage Securities Trust, CMO Series 7 Short-Intermediate Portfolio
    ("Short-Intermediate Portfolio").  The Trust was formed to obtain safety
    of capital and a high level of current distributions of interest income
    through investment in a fixed portfolio of CMOs.  A CMO is a multiclass
    bond backed by a pool of mortgage pass-through securities or mortgage
    loans.  CMOs are also known as "real estate mortgage investment conduits"
    (REMICs).  As a result of the 1986 Tax Reform Act, most CMOs are issued in
    REMIC form to create a certain tax advantage for the issuer.  The terms
    CMO and REMIC are used interchangeably.  The Trust seeks to obtain a
    higher yield than fixed income investments with comparable AAA ratings.

              The Short-Intermediate Portfolio may invest in one or more types
    of CMOs including:  standard bonds which accrue interest at a fixed rate,
    payable at regular intervals from issuance to maturity or repayment of
    principal, if earlier; compound interest bonds upon which interest will
    accrue but will not be payable (but will be added to the principal amount
    of the compound interest bonds), until all bonds issued by the same issuer
    in the same series of CMOs, but which have an earlier stated maturity date
    than the compound interest bonds, have been paid in full; adjustable rate
    bonds upon which the interest rate may increase or decrease at one or more
    future dates; floating rate bonds upon which interest accrues at a
    floating rate that may be related directly or inversely (although not
    necessarily proportionately) to an index; planned amortization bonds or
    targeted amortization bonds that are expected to receive payments in
    reduction of their outstanding principal amount in specified amounts and
    on specified dates in a manner designed to provide as much assurance as
    possible that those bonds will be repaid within the period of time
    specified in the prospectus, offering circular or other documents pursuant
    to which the bonds were offered for sale; bonds entitled to receive
    payments of principal only; and support class bonds whose function is to
    support the amortization schedule of the planned amortization bonds or
    targeted amortization bonds.  (See "The Trusts--Portfolios" in Part B of
    this Prospectus.)

              All of the CMOs in the Trust are backed by underlying mortgage-
    backed securities which are pledged as collateral to secure payment of
    principal and interest on the CMOs.  Each of these mortgage-backed
    securities is guaranteed as to the payment of principal and interest by
    either the Government National Mortgage Association ("GNMA"), the Federal
    National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
    Corporation ("FHLMC").  All of the CMOs in the Trust are issued by GNMA,
    FNMA or FHLMC or are otherwise rated AAA by Standard & Poor's Corporation
    ("Standard & Poor's") and therefore, the Units of the Trust are rated AAA
    by Standard & Poor's.  There can be no assurance that the Trust's
    investment objectives can be achieved.  Investments in the Trust should be
    made with an understanding of the risks inherent in an investment in CMOs. 
    (See "The Trust--Special Risk Considerations" in this Part A.)  Each Unit
    of the Trust represents an undivided interest in the principal and net
    income of the Trust in the ratio of one thousand Units for the indicated
    principal amount of Securities in the Trust.  (See "The Trust--
    Organization" in Part B of this Prospectus.)  (For the specific number of
    Units in the Trust, see "Summary of Essential Information" in this
    Part A.)

              Generally, CMOs are designed to provide a substantial degree of
    prepayment and reinvestment risk protection as compared to other mortgage
    related securities.  The CMOs may have been issued as debt obligations of
    a trust or corporation or as certificated interests representing
    beneficial ownership in a pool of mortgage-backed securities (See "The
    Trusts--The Securities" in Part B of this Prospectus for further
    description and examples) which trust, corporation or pool may have been
    established for the sole purpose of issuing CMOs by any of GNMA, FNMA or
    FHLMC or by a private business organization.  Such private business
    organizations are typically single-purpose corporations established by
    mortgage-banking institutions for the sole purpose of issuing CMOs.  Any
    CMOs in the Trust that have been issued by private business organizations
    have been rated AAA by Standard & Poor's.  The sole assets of the issuers
    of the CMOs are the underlying mortgage-backed securities.  If the
    collateral securing the Securities of these issuers is insufficient to
    make payments on those Securities, it is unlikely that any other assets of
    these issuers will be available for payment of the deficiency.  The
    underlying mortgage-backed securities which are pledged as collateral to
    secure the payment of principal and interest on the CMOs may be (i) "fully
    modified pass-through" mortgage-backed certificates, guaranteed by GNMA
    ("Ginnie Maes"), (ii) mortgage pass-through certificates guaranteed by
    FNMA ("Fannie Maes") or (iii) mortgage participation certificates
    guaranteed by FHLMC ("Freddie Macs").  The full faith and credit of the
    United States is pledged to the payment of all amounts guaranteed by GNMA. 
    However, payments guaranteed by FNMA and FHLMC are not guaranteed by the
    United States and neither the CMOs in the Trust nor any underlying Fannie
    Maes or Freddie Macs constitute a debt or obligation of the United States
    or any of its agencies.  The Units of the Trust, as such, are not
    guaranteed by any of GNMA, FNMA, FHLMC, the United States or any of its
    agencies.  Additionally, CMOs that are issued by GNMA, FNMA or FHLMC or by
    any entity established by GNMA, FNMA or FHLMC are guaranteed as to payment
    of principal and interest by GNMA, FNMA or FHLMC, respectively.  The
    guaranty obligations of GNMA with respect to any Ginnie Maes or any CMOs
    are supported by the full faith and credit of the United States.  However,
    the guaranty of obligations of FNMA and FHLMC with respect to any Fannie
    Maes or Freddie Macs or any CMOs are obligations of FNMA and FHLMC only
    (limited by their respective credit capabilities) and are not supported by
    the full faith and credit of the United States or any other governmental
    entity.

              CMO Structure.  CMOs are generally issued as a series of
    different classes.  An issue of CMOs generally is backed by a larger
    number of mortgages than a pool of Ginnie Maes, Fannie Maes or Freddie
    Macs, thus allowing greater statistical prediction of prepayment
    characteristics.  Interest and principal payments on the mortgages
    underlying any series will first be applied to meet the interest payment
    requirements of each class in the series other than any class in respect
    of which interest accrues but is not paid or any "principal only" class. 
    Principal payments on the underlying mortgages are thereafter generally
    applied to pay the principal amount of the class that has the earliest
    maturity date.  Once that class is retired, the principal payments on the
    underlying mortgages are applied to the class with the next earliest
    maturity date.  This is repeated until all classes are paid.  Therefore,
    while each class of CMOs remains subject to prepayment as the underlying
    mortgages prepay, structuring several classes of CMOs in the stream of
    principal payments allows a more predictable estimate of the period of
    time when any one class is likely to be repaid.  The estimate can be even
    closer with a class of planned amortization bonds or targeted amortization
    bonds.  The amortization schedule for these CMOs is structured so that, at
    specified prepayment rates within a range, their principal will be repaid
    at specified times and in specified amounts.  However, if any series of
    CMOs contains a class of planned amortization bonds or targeted
    amortization bonds, then the other classes in that series may not be
    retired in an order of priority determined strictly with reference to
    their maturity dates.  

              These other classes are often referred to as "support classes"
    because their function is to support the amortization schedule of the
    planned amortization bonds or targeted amortization bonds.  If the rate of
    prepayment on the underlying mortgages is faster than assumed, then
    classes with maturity dates later than the planned amortization bonds or
    targeted amortization bonds may be retired earlier than estimated to
    ensure that the planned amortization bonds or targeted amortization bonds
    receive the principal payments required by their amortization schedule. 
    Similarly, if the rate of prepayments is slower than anticipated, then
    earlier support classes may be retired later than estimated.  Hence,
    support classes of a series that contains planned amortization bonds or
    targeted amortization bonds have less predictable prepayment
    characteristics than classes of a series that does not.  This lack of
    predictability regarding prepayments also causes support class bonds to
    have greater market value fluctuation than other classes of a CMO.  (See
    "Description of Portfolio" for the number of planned amortization bonds,
    targeted amortization bonds or support class bonds in the Trust
    portfolio.)  The rate of prepayment on the underlying mortgages of a CMO
    will most likely decline as interest rates increase.  If the rate of
    prepayment declines, the weighted average life of the support class bonds
    will most likely increase and, in some cases, the decline will impact the
    yield and market value of these Securities.  This may cause an investor's
    principal in a support class bond to be outstanding for a longer period of
    time than initially anticipated.  Conversely, if interest rates decline,
    prepayments on the underlying mortgages will most likely increase, and the
    weighted average life of the support class bonds may be shorter than
    anticipated.  A holder of a support class bond in these situations may be
    unable to reinvest the proceeds of these principal distributions at an
    effective interest rate equal to the specified coupon rate on the original
    support class bond.  Therefore, an investor expecting to earn a fixed
    return for a fixed number of years may find the life of a support class
    investment decreases as interest rates fall and increases as they rise. 
    Investors should be aware that the Federal Financial Institutions
    Examination Council recently announced that certain high-risk CMO tranches
    are generally not suitable investments for depository institutions.   

              Some of the CMOs in the Trust may be either a class of
    Guaranteed REMIC Certificates ("REMIC Certificate") issued by FNMA or a
    class of REMIC Certificates issued by FHLMC.  A FNMA REMIC Certificate
    represents a beneficial ownership interest in a certain class of a FNMA
    REMIC Trust consisting of Fannie Maes, each of which in turn represents a
    beneficial interest in a pool of first lien, single-family, fixed-rate
    residential mortgage loans.  FNMA REMIC Certificates are issued pursuant
    to trust agreements executed by FNMA in both its corporate capacity and
    its capacity as trustee.  A FNMA REMIC Certificate evidences a beneficial
    ownership interest in the distribution of principal and interest on the
    underlying Fannie Maes, subject to certain limits and in an order of
    distribution established for the particular FNMA REMIC Trust.  Each FNMA
    REMIC Certificate is backed by the guaranty obligation of FNMA to
    distribute on a timely basis required installments of principal and
    interest and to distribute the principal balance of the FNMA REMIC
    Certificate in full no later than an established final distribution date,
    notwithstanding insufficiency of funds from the underlying Fannie Maes.  A
    FHLMC REMIC Certificate represents a beneficial ownership interest in a
    certain class of a pool of Freddie Macs, each of which in turn represents
    undivided interests in discrete pools of fixed-rate, first lien,
    residential mortgages or participations therein purchased by FHLMC.  FHLMC
    REMIC Certificates are issued pursuant to multiclass mortgage
    participation certificate agreements executed by FHLMC.  A FHLMC REMIC
    Certificate evidences a beneficial ownership interest in the distributions
    of principal and interest on the underlying Freddie Macs, subject to
    certain limits and in an order of distribution established for the
    particular FHLMC REMIC pool.  Each FHLMC REMIC Certificate is backed by
    the guaranty obligation of FHLMC to distribute required interest payments
    on a timely basis and to distribute required principal payments as
    principal payments on the underlying Freddie Macs are required to be made. 
    Except with respect to certain issues of "Gold" PCs, FHLMC generally does
    not guarantee timely payment of principal but does guarantee ultimate
    payment.  Both FNMA REMIC Certificates and FHLMC REMIC Certificates pay
    interest monthly.  (See "The Trusts--The Securities" in Part B of this
    Prospectus for a description of FHLMC Gold PCs.)

              If FNMA or FHLMC were unable to fulfill its guarantees,
    distributions to holders of REMIC Certificates such as the Trusts would
    consist solely of payments and other recoveries upon the mortgages
    underlying the pledged Fannie Maes or Freddie Macs, respectively, and,
    accordingly, delinquencies and defaults would diminish distributions to
    the holders.  (See "Description of Portfolio" for the number of FNMA REMIC
    Certificates and FHLMC REMIC Certificates in the Trust portfolio.)

              Some of the CMOs in the Trust may be a class of compound
    interest bonds or principal only bonds.  Interest on compound interest
    bonds is accrued and is added to principal.  Such interest is not paid
    until all classes of CMOs issued in the same series with earlier final
    distributions dates are paid in full.  Principal only bonds entitle the
    holder to no payments of interest but the holder will receive cash flow
    from the amortization of principal and prepayments.  Both compound
    interest bonds and principal only bonds sell at a deep discount from par. 
    The Sponsors believe that a portfolio with a limited amount of compound
    interest bonds and principal only bonds will assist the Trust in achieving
    its objective of preserving capital.  Since the principal only bond will
    accrue to par if held to maturity, the holder of such a bond would receive
    a full return of his or her initial investment upon maturity of the bond. 
    In addition, compound interest bonds also assist in the preservation of
    capital as interest which accrues on these bonds is added to principal. 
    (See "Description of Portfolio" for the amount of Securities in the Trust
    that are a class of compound interest bonds or principal only bonds.)

              Special Risk Considerations.  An investment in Units of the
    Trust should be made with an understanding of risks which an investment in
    fixed rate CMOs may entail, including the risk that the value of the
    portfolio and, hence, the value of the Units will decline with increases
    in interest rates and that the life of the CMOs in the portfolio depends
    on the actual prepayments received on the underlying mortgage-backed
    securities, the timing of which cannot be determined but which may be
    sooner or later than anticipated, especially if interest rates decline. 
    The potential for appreciation, which could otherwise be expected to
    result from a decline in interest rates, may be limited by any increased
    prepayments by mortgagors.  Investors should also note that prepayments of
    principal on CMOs purchased at a premium over par will result in some loss
    on investment while prepayments on CMOs purchased at a discount from par
    will result in some gain on investment.  Also, if interest rates rise, the
    prepayment risk of higher yielding, premium CMOs and the prepayment
    benefit for lower yielding, discount CMOs will be reduced.  (See "The
    Trusts--Life of the Securities and of the Trusts" in Part B of this
    Prospectus.)  In addition, a number of factors, including the extent of
    prepayments of principal on the underlying mortgage-backed securities,
    affect the availability of funds for payment of principal of bonds on any
    payment date and, therefore, the timing of principal payments on each
    class of such bonds.

              While all of the mortgage-backed securities underlying each of
    the CMOs in the Trust are guaranteed as to the payment of principal and
    interest by GNMA, FNMA or FHLMC, the CMOs in the Trust represent
    obligations solely of the issuers of those CMOs and are not themselves
    insured or guaranteed by GNMA, FNMA or FHLMC, or any other governmental
    agency.  If a default were to occur with respect to any of the CMOs, there
    can be no assurance that the collateral securing such bonds would be
    sufficient to pay the principal and interest then due.

              CMOs are generally not listed on a national securities exchange
    or on the National Association of Securities Dealers Automated Quotation
    System, Inc.  Whether or not CMOs are listed on a national securities
    exchange, the principal trading market for the CMOs will generally be in
    the over-the-counter market.  As a result the existence of a liquid
    trading market for CMOs may depend on whether dealers will make a market
    in CMOs.  There can be no assurance that a market will be made for any of
    the CMOs in the Trust, that any market for the CMOs in the Trust portfolio
    will be maintained or of the liquidity of the CMOs in the Trust in any
    markets made.  The price at which the CMOs in the Trust may be sold to
    meet redemptions and the value of the Trust will be adversely affected if
    trading markets for the CMOs in the Trust are limited or absent.  (See
    "The Trust--Liquidity" in Part B of this Prospectus.)  In addition, the
    Trust may be restricted under the Investment Company Act of 1940 from
    selling securities to the Sponsors.  However, taking into account the
    foregoing and other factors, the Sponsors believe that the nature of the
    GNMA, FNMA or FHLMC guarantees of any securities that have been issued by
    them, respectively, and the nature of the Ginnie Maes, Fannie Maes or
    Freddie Macs securities payments of principal and interest due on the
    Securities make the Securities adequately marketable for purposes of
    redemptions of Units by the Trustee (see "Redemption" in Part B of this
    Prospectus).

              Investors should note that all of the CMOs in the Trust have
    been issued by trusts, corporations or other entities that have elected to
    be treated as Real Estate Mortgage Investment Conduits ("REMICs").  As
    such, Certificateholders will be required to include in income their
    respective pro rata share of interest on each Security (whether or not the
    Security has original issue discount) as interest accrues, whether or not
    the Certificateholder is an accrual method taxpayer.  (See "Tax Status" in
    Part B of this Prospectus.)

              The principal amount of Securities actually deposited in each
    Trust is affected by the prepayment estimate or factor for each CMO.  If
    the prepayment estimate or factor is adjusted because the level of actual
    prepayments increases with respect to a particular CMO prior to the
    settlement date of the Securities, the actual principal amount of
    Securities deposited in the Trust may be less than the amount noted above
    and the excess of any cash returned to the Trust as a result of these
    prepayments will be held in the Trust's principal account.  Cash balances
    maintained in the principal account do not generate income for the Trust.

              Educational material regarding CMOs is available upon request,
    from the Sponsor.

              PUBLIC OFFERING PRICE.  The secondary market Public Offering
    Price per 1,000 Units of the Trusts is equal to the aggregate bid side
    evaluation of the underlying Securities in a Trust divided by the number
    of Units outstanding times 1,000, plus a sales charge of 3.5% of the
    Public Offering Price per 1,000 Units or 3.627% of the net amount invested
    in Securities per 1,000 Units of the Short-Intermediate Portfolio.  In
    addition, accrued interest to the expected date of settlement is added to
    the Public Offering Price.  If the Units of the Short-Intermediate
    Portfolio had been purchased on the Evaluation Date, the Public Offering
    Price per 1,000 Units would have been $243.77, plus accrued interest of
    $2.01, for a total of $245.78.  The Public Offering Price per 1,000 Units
    may vary on a daily basis in accordance with the fluctuations in the
    aggregate bid price of the Bonds.  (See "Public Offering" in Part B of
    this Prospectus.)

              The figures above assume a purchase of 1,000 Units.  The price
    of a single Unit, or any multiple thereof, is calculated by dividing the
    Secondary Market Public Offering Price per 1,000 Units by 1,000 and
    multiplying by the number of Units.

              DISTRIBUTIONS.  Distributions of principal and interest income,
    less expenses, will be made by the Trusts monthly on the 20th of each
    month.  (See "Rights of Certificateholders--Interest and Principal
    Distributions" in Part B of this Prospectus.  For the estimated amount of
    distributions see "Summary of Essential Information" for the Trust in this
    Part A.) 

              ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN. 
    Estimated Long Term Return for the Trust is calculated by:  (1) computing
    the yield to maturity for each CMO in the Trust's portfolio in accordance
    with accepted CMO practices, which practices take into account not only
    the interest payable on the CMO but also the amortization of premiums or
    accretion of discounts, if any, and estimates of projected prepayments;
    (2) calculating the average of the yields for the CMOs in the Trust's
    portfolio by weighing each CMO's yield by the market value of the CMO and
    by the amount of time remaining to the date to which the CMO 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 Certificateholders.  The resulting Estimated Long Term
    Return represents a measure of the return to Certificateholders earned
    over the estimated life of the Trust.  (For the Estimated Long Term Return
    to Certificateholders per 1,000 Units, see "Summary of Essential
    Information" for the Trust.) 

              Estimated Current Return for the Trust is calculated by dividing
    the Estimated Net Annual Interest Income per 1,000 Units by the Public
    Offering Price per 1,000 Units.  In contrast to the Estimated Long Term
    Return, the Estimated Current Return does not take into account estimates
    of prepayments or the amortization of premium or accretion of discount, if
    any, on the CMOs in the portfolio of the Trust.  On the Evaluation Date,
    the Estimated Net Annual Interest Income per 1,000 Units divided by the
    Public Offering Price per 1,000 Units resulted in the Estimated Current
    Return stated for the Trust under "Summary of Essential Information" in
    Part A.

              If the CMOs in the Trust are priced at a discount, the Estimated
    Current Return will generally be lower relative to the Estimated Long Term
    Return, whereas if the CMOs are priced at a premium, the Estimated Current
    Return will generally be higher relative to the Estimated Long Term
    Return.  This is because Estimated Current Return reflects primarily the
    interest rate on the CMOs, while Estimated Long Term Return reflects yield
    and timing of principal payments, and thus increases when the principal
    returned is greater than the price paid for the CMOs (discount) and
    decreases when the principal returned is lower than the price paid
    (premium).  Estimated Long Term Return is calculated using an estimated
    average life for the CMOs in the Trust.  Estimated average life is an
    essential factor in the calculation of Estimated Long Term Return.  When
    the Trust has a shorter average life than is estimated, Estimated Long
    Term Return will be higher if the Trust contains CMOs priced at a discount
    and lower if the CMOs are priced at a premium.  Conversely, when the Trust
    has a longer average life than is estimated, Estimated Long Term Return
    will be lower if the CMOs are priced at a discount and higher if the CMOs
    are priced at a premium.  To calculate estimated average life several
    assumptions are made to derive an estimated prepayment rate for the
    mortgages underlying the Ginnie Maes, Fannie Maes or Freddie Macs that may
    back the CMOs in the Portfolio; the calculation of estimated prepayment
    rates is based upon actual recent prepayments and analysis of several
    factors including, among other things, the spread between present market
    interest rates and the rate on the mortgages and the housing environment. 
    The estimated prepayment rate that is derived is then applied to retire
    the principal amount of each CMO class of the same series as each CMO in
    the Trust, including those CMOs in the Trust, according to the specific
    principal reduction schedule of each series.  For a more detailed
    explanation of the calculation of estimated average life, see "Estimated
    Long Term Return and Estimated Current Return" in Part B of this
    Prospectus.  The estimated average life for the Trust is subject to change
    with alterations in the data used in any of the underlying assumptions. 
    The actual average lives of the CMOs in the Trust portfolio and the actual
    long term returns will be different from the estimated average lives and
    the estimated long term returns.

              The Estimated Net Annual Interest Income per 1,000 Units 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, prepayment,
    maturity, sale or other disposition of the CMOs 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 CMOs.  Therefore, there is no
    assurance that the present Estimated Current Return or Estimated Long Term
    Return will be realized in the future.

              Market for Units.  The Sponsors, although not obligated to do
    so, intend to maintain a secondary market for the Units of the Trust.  The
    secondary market repurchase price will be based on the aggregate bid side
    evaluation of the Securities in the Trusts; and the reoffer price will be
    based on the aggregate bid side evaluation of the Securities, divided by
    the number of Units outstanding times 1,000, plus a sales charge of 3.5%
    (3.627% of the net amount invested), plus net accrued interest for the
    Short-Intermediate Portfolio.  If a market is not maintained a
    Certificateholder will be able to redeem his Units with the Trustee at a
    price based on the aggregate bid side evaluation of the Securities.  (See
    "Sponsor Repurchase" in Part B of this Prospectus.)

              Total Reinvestment Plan.  Distributions from the Trust are made
    to Certificateholders monthly.  The Certificateholder has the option,
    however, of either receiving his interest check, together with any
    principal payments, from the Trustee or participating in a reinvestment
    program offered by the Sponsors in shares of The Treasurer's Fund, Inc.,
    U.S. Treasury Money Market Portfolio (the "Fund").  Gabelli-O'Connor Fixed
    Income Mutual Funds Management Co. serves as the investment advisor of the
    Fund and GOC Fund Distributors, Inc. serves as distributor for the Fund. 
    Participation in the reinvestment option is conditioned on the Fund's
    lawful qualification for sale in the state in which the Certificateholder
    is a resident.  The Plan is not designed to be a complete investment
    program.  See "Total Reinvestment Plan" in Part B of this Prospectus.  The
    shares of the Fund are not rated by Standard & Poor's.

     (1)  Estimated current return represents annual interest income after
          estimated annual expenses divided by the Public Offering Price,
          including for the Short-Intermediate Portfolio, a 3.5% maximum sales
          charge.  Estimated long term return is the net annual percentage
          return based on the yield on each underlying Security in the Trust
          weighted to reflect market value and estimated average life.  The
          estimated weighted average life to maturity of the Trust is an
          estimate based upon various assumptions discussed more fully under
          "Estimated Long Term Return and Estimated Current Return" in Part B
          of this Prospectus.  Estimated long term return is adjusted for
          estimated expenses and the maximum public offering price but not for
          delays in the Trust's distribution of income.  Estimated current
          return shows current annual cash return to investors while estimated
          long term return shows the return on Units held to estimated average
          life, reflecting prepayments of principal, maturities, discounts and
          premiums on underlying Securities.  Actual returns will vary with
          purchase price, payments and prepayments of principal on the
          underlying Ginnie Maes, Fannie Maes or Freddie Macs which back the
          Securities, and changes in Trust income after expenses.  These
          returns do not include the effects of any delay in payments to
          Unitholders and a calculation which includes those effects would be
          lower.  See "Estimated Long Term Return and Estimated Current
          Return" in Part B of this Prospectus.

                         INFORMATION REGARDING THE TRUSTS
                                AS OF JUNE 30, 1994


    Description of Portfolio

          The Trust consists of 2 issues of CMOs.  The Sponsors have not
    participated as a sole underwriter or manager, co-manager or member of an
    underwriting syndicate from which any of the initial aggregate principal
    amount of the CMOs in the Portfolio were acquired.  None of the CMOs have
    been issued by entities created by GNMA, 100% have been issued by entities
    created by FNMA, none have been issued by entities created by FHLMC and
    none have been issued by private issuers.  All of the CMOs in the Trust
    have been issued by trusts, corporations or other entities that have
    elected to be treated as Real Estate Mortgage Investment Conduits.  The
    CMOs in the Trust have stated final distribution dates ranging from
    February 25, 2018 through December 25, 2018 and had estimated average
    lives (based upon estimated prepayment rates at the initial date of
    deposit) ranging from 7.88 to 9.19 years.

          All $3,250,000 of the principal amount of the Securities in the
    Trust are planned amortization bonds or targeted amortization bonds.  None
    of the principal amount of the Securities are support class bonds that are
    part of a series that contains planned amortization bonds or targeted
    amortization bonds.  As of June 30, 1994, $3,250,000 (100% of the
    principal amount of the Securities in the Trust) are FNMA REMIC
    Certificates.  None of the principal amount of the Securities in the Trust
    are a class of compound interest bonds or principal only bonds.  The Bonds
    may also be subject to other calls, which may be permitted or required by
    events which cannot be predicted (such as destruction, condemnation,
    termination of a contract, or receipt of excess or unanticipated
    revenues).

          As of June 30, 1994, 61.5% of the aggregate principal amount of the
    Securities in the Trust were acquired at a discount from par, 38.5% of the
    Securities in the Trust were acquired at a premium and none were acquired
    at par.  A Certificateholder may receive more or less than his original
    purchase price upon disposition of his Units because the value of the
    Units fluctuates with the value of the underlying Securities.

The Sponsor, Trustee and Certificateholders
Mortgage Securities Trust, CMO Series 7 Short-Intermediate:


We have audited the accompanying statement of net assets, including the
portfolio, of Mortgage Securities Trust, CMO Series 7 Short-Intermediate
as of June 30, 1994, and the related statements of operations and
changes in net assets for each of the years in the two year period then
ended and for the period December 11, 1991 (date of deposit) to June 30,
1992.  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

MORTGAGE SECURITIES TRUST, CMO SERIES 7

SHORT-INTERMEDIATE

Notes to Financial Statements

June 30, 1994, 1993 and 1992



(1)  Organization and Financial and Statistical Information

Mortgage Securities Trust, CMO Series 7 (Trust) was organized on
December 11, 1991 (date of deposit) by Bear, Stearns & Co. Inc. and
Gruntal & Co., Incorporated (Co-Sponsors) 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

United States Trust Company 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
Standard & Poor's Corporation (Evaluator).  The market value of the
investments is based upon the bid prices for the securities at the
end of the period, except that the market value on the date of deposit
represents the cost to the 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
on a monthly basis.

The Trust Indenture and Agreement further requires that principal
received from the disposition of securities, other than those
securities 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 two
year period ended June 30, 1994 and the period December 11, 1991 (date
of deposit) to June 30, 1992.

The Trust Indenture and Agreement also requires the Trust to redeem
units tendered.  1,116,666 and 16,719 were redeemed in the years ended
June 30, 1994 and 1993, respectively.  No units were redeemed in the
period ended June 30, 1992.

(5)  Net Assets

At June 30, 1994, the net assets of the Trust represented the interest
of Certificateholders as follows:


Original cost to Certificateholders               $  14,578,407

Less initial gross underwriting commission             (510,244)



                                                     14,068,163

Accumulated cost of securities
sold or called                                      (10,972,750)

Net unrealized appreciation                              67,380

Undistributed net investment income                      40,902



Total                                             $   3,203,695


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 14,578,407
units of fractional undivided interest of the Trust as of the
date of deposit.

                                     THE TRUST



    Organization

              "Mortgage Securities Trust CMO Series" (the "Trusts") consists
    of the "unit investment trusts" designated as set forth in Part A.*  The
    Trusts were created under the laws of the State of New York pursuant to a
    Trust Indenture and Agreement** (the "Trust Agreement"), dated the Date
    of Deposit, among Bear, Stearns & Co. Inc., and Gruntal & Co.,
    Incorporated as Sponsors, United States Trust Company of New York, as
    Trustee, and Kenny S&P Evaluation Services as Evaluator.



    *    This Part B relates to the outstanding series of Short-Intermediate
         Portfolio, Intermediate Portfolio or Long-Intermediate Portfolio as
         reflected in Part A attached hereto.

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

       
              The Trusts contain different issues of collateralized mortgage
    obligations ("CMOs" or "Securities").  On the Date of Deposit the Sponsors
    deposited with the Trustee the underlying Securities as set forth in
    Part A, including delivery statements relating to contracts for the
    purchase of such Securities, and cash or an irrevocable letter of credit
    issued by a major commercial bank in the amount required for such
    purchases.  Thereafter, the Trustee delivered to the Sponsors units of
    interest ("Units") representing the entire ownership of the Trusts.  Each
    "Unit" of a Trust outstanding on the Evaluation Date represents an
    undivided interest or pro rata share in the principal and interest of a
    Trust in the ratio of one Unit for the indicated principal amount of
    Securities in that Trust on such date as specified in Part A of this
    Prospectus.  Certificateholders will have the right to have their Units
    redeemed (see "Redemption") at a price based on the aggregate bid side
    evaluation of the Securities.  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 Sponsors or the
    underwriters (the "Underwriters"), or until the termination of the Trust
    Agreement.
        

    Objectives

              The Trusts offer investors the opportunity to participate in a
    portfolio of collateralized mortgage obligations with a greater degree of
    safety and diversification than they might be able to acquire themselves. 
    The objectives of the Trusts are to obtain safety of capital and a high
    level of current distribution of interest income through investment in a
    fixed portfolio of CMOs.  The Trusts seek to obtain a higher yield than
    fixed income investments with comparable AAA ratings.  These CMOs may have
    been issued as debt obligations of a trust or corporation or as
    certificated interests representing beneficial ownership in pools of
    mortgage-backed securities.  All of the CMOs in the Trusts are backed by
    underlying mortgage-backed securities which are pledged as collateral to
    secure payment of principal and interest on the CMOs.  Each of these
    mortgage-backed securities is guaranteed by either the Government National
    Mortgage Association ("GNMA"), the Federal National Mortgage Association
    ("FNMA"), or the Federal Home Loan Mortgage Corporation ("FHLMC").  All of
    the CMOs in the Trusts are issued by GNMA, FNMA or FHLMC or are otherwise
    rated AAA by Standard & Poor's and, therefore, the Units of the Trusts are
    rated AAA by Standard & Poor's Corporation.  However, neither GNMA, FNMA,
    FHLMC, the United States or any of its agencies guarantees payment on
    Units of the Trusts.  The full faith and credit of the United States is
    pledged to the payment of all amounts guaranteed by GNMA.  However,
    payments guaranteed by FNMA and FHLMC are not guaranteed by the United
    States and neither the CMOs in the Trusts nor any underlying Fannie Maes
    or Freddie Macs constitute a debt obligation of the United States or any
    of its agencies.

       
              Investors should be aware that there is no assurance that the
    Trusts' objectives will be achieved.  An investment in Units of the Trusts
    should be made with an understanding of the risks which an investment in a
    fixed portfolio of fixed rate CMOs may entail, including the risk that the
    value of a Trust portfolio and hence of the Units will decline with
    increases in interest rates.  It should also be noted that the potential
    for appreciation on the Securities which would otherwise be expected to
    result from a decline in interest rates, may tend to be limited by any
    increased prepayments including selling the property, refinancing the
    mortgage or otherwise paying off the loan in whole or in part by
    mortgagors as interest rates decline.  In addition, prepayments of
    principal on Securities purchased at a premium over par will result in
    some loss on investment, while prepayments on Securities purchased at a
    discount from par will result in some gain on investment.  The Sponsors
    cannot predict future economic policies or their consequences or,
    therefore, the course or extent of any similar fluctuations in the future. 
    Educational materials regarding CMOs, including a discussion of risk
    factors, investment features of CMOs and questions an investor should ask
    before investing are available, upon request, from the Sponsor.
        

              Since disposition of Units prior to final liquidation of the
    Trusts may result in an investor receiving less than the amount paid for
    such Units (see "Comparison of Public Offering Price, Sponsors' Repurchase
    Price and Redemption Price"), the purchase of a Unit should be looked upon
    as a long-term investment.  Neither the Trusts nor the Total Reinvestment

              The portfolios of the Trusts consist of the Securities described
    in "Description of Portfolio" in Part A.

              In selecting Securities for deposit in the Trust, the Sponsors
    considered the following factors, among others:  (i) the types of CMOs
    available, (ii) the yield and price of the Securities relative to other
    comparable mortgage-backed securities, (iii) the estimated average lives
    and prepayment schedules of the Securities, (iv) the payment provisions
    applicable to the Securities, and (v) whether the Securities were issued
    after July 18, 1984 if interest thereon is United States source income.

              The Trust consists of the Securities listed under "Portfolio" in
    Part A as long as they may continue to be held from time to time in the
    Trust together with accrued and undistributed interest thereon and
    undistributed and uninvested cash realized from the disposition or
    redemption of Securities (see "Trust Administration--Portfolio
    Supervision"). 

       
              A CMO is a multiclass bond backed by a pool of mortgage pass-
    through securities or mortgage loans. CMOs are also known as "real estate
    mortgage investment conduits" (REMICs). As a result of the 1986 Tax Reform
    Act, most CMOs are issued in REMIC form to create a certain tax advantage
    for the issuer.  The terms CMO and REMIC are used interchangeably.  CMOs
    generally are bond-like tranches of the cash flow from a mortgage pool. 
    An issue of CMOs generally is backed by a larger number of mortgages than
    a pool of Ginnie Maes, Fannie Maes or Freddie Macs, thus allowing greater
    statistical prediction of prepayment characteristics.  CMOs also differ
    from regular mortgage-backed securities in that the cash flow on the
    mortgage pool are applied to the various classes of any series of CMOs in
    the order specified by that series, rather than to each CMO in the series
    pro rata.
        

    The Securities

              The Securities in the Long-Intermediate Trust portfolio consist
    of support class bonds, described below.  The Securities in the
    Intermediate Trust Portfolio may consist primarily of planned amortization
    or targeted amortization bonds.  The Securities in the Short-Intermediate
    Portfolio may consist of one or more of several classes of CMOs,
    including:

              Standard (Plain Vanilla) Bonds:  This class of CMO accrues
    interest at a fixed rate on its outstanding principal amount.  The
    interest is payable monthly, quarterly or semi-annually as specified. 
    Holders of Standard Bonds receive only interest until all CMOs issued in
    the same series with earlier final distribution dates have been paid in
    full.  In addition, some Standard Bonds may be issued as a support class
    to Planned Amortization Bonds or Targeted Amortization Bonds (see below).

              Compound Interest Bonds:  Interest accrues upon this class of
    CMO but is not payable until all classes of CMOs issued in the same series
    with earlier final distribution dates have been paid in full.  Interest
    that accrues but is not paid is added to the principal amount of the
    Compound Interest Bond.

              Adjustable Rate Bonds:  Interest rates on this class of CMO may
    increase or decrease at one or more specified dates according to the
    documentation governing their issuance.

              Floating Rate Bonds:  Interest rates on these classes of CMOs
    vary directly or inversely (although not necessarily proportionately) in
    relation to generally accepted market interest rate indices.  The interest
    rate is usually capped to limit the extent of over-collateralization with
    mortgage-backed securities required in order to ensure that there is
    sufficient cash flow to service all the classes of CMOs in that series.

       
              Planned Amortization Bonds or Targeted Amortization Bonds and
    Support Bonds:  Planned Amortization or Target Amortization classes of
    CMOs receive payments of principal according to a planned schedule to the
    extent that prepayments on the underlying mortgage-backed securities occur
    within a broad time period (the "Protection Period").  The principal is
    reduced only in specified amounts at specified times resulting in greater
    predictability of principal payments for the Planned Amortization Bonds or
    Targeted Amortization Bonds.  The greater predictability of cash flows for
    Planned Amortization and Target Amortization Bonds is achieved by creating
    other classes of bonds commonly called "support classes."  Support classes
    generally receive principal payments on any payment date only if scheduled
    payments have been made on specified Planned Amortization and/or Target
    Amortization classes.  Support classes absorb the variability of principal
    cash flows from the underlying mortgage-backed securities.  For instance,
    if prepayments on the underlying mortgage-backed securities occur at a
    rate greater or less than that provided for by the Protection Period, then
    the excess or deficiency of cash flows generated is absorbed by the
    support classes of CMOs in the particular series until the principal
    amount of each of the other classes has been paid in full, resulting in
    less predictability of cash flows for the support classes.  Accordingly,
    the support classes are subject to a higher level of risk than the Planned
    Amortization or Target Amortization Bonds because the support classes have
    a higher degree of average life variability.  Because the support classes
    have a higher degree of average life variability, they generally pay a
    higher yield.
        
              Principal Only Bonds:  This class of stripped CMOs has the right
    to all principal payments from the underlying mortgage-backed securities. 
    Principal Only Bonds sell at a deep discount.  The return on a Principal
    Only Bond increases the faster prepayments are received at par.  The
    return on a Principal Only Bond decreases if the rate of prepayment is
    slow.  Slow prepayment can also cause great delays in recognizing gains.

              Pledged as collateral to secure the payment of interest and
    principal on each type of CMO in the Portfolio will be Ginnie Maes, Fannie
    Maes or Freddie Macs, guaranteed by GNMA, FNMA and FHLMC, respectively. 
    The Units of the Trust, however, will not be guaranteed by GNMA, FNMA,
    FHLMC, the United States or any of its agencies.  The Trust may contain
    CMOs, the collateral pledged to secure which, are mortgages referred to as
    "Relocation Mortgages."  Relocation Mortgages are issued expressly to
    finance home purchases by transferred employees.  Since such mortgages are
    related to the relocation of the individual rather than housing activity
    and mortgages rates generally, the anticipated prepayment rate for them is
    different than other individual mortgage-backed securities.  Historically,
    prepayment speeds with respect to Relocation Mortgages are faster and less
    interest rate sensitive than traditional single family mortgages. 
    Therefore, with respect to any CMOs in the Trust supported by such
    Relocation Mortgages, the Trust would expect to receive prepayment of
    principal on such instruments at a faster rate than that with respect to
    other CMOs in the Trust.

              GNMA.  The Government National Mortgage Association is a wholly-
    owned corporate instrumentality of the United States within the Department
    of Housing and Urban Development.  The National Housing Act of 1943, as
    amended, authorizes GNMA to guarantee the timely payment of the principal
    of, and interest on, certificates which are based on and backed by a pool
    of mortgage loans insured by the Federal Housing Administration ("FHA"),
    or partially guaranteed by the Veteran's Administration ("VA").  In order
    to meet its obligations under such guaranty, GNMA may issue its general
    obligations to the United States Treasury in an amount which is at any
    time sufficient to enable GNMA, with no limitations as to amount, to
    perform its obligations under its guaranty.  In the event it is called
    upon at any time to make good its guaranty, GNMA has the full power and
    authority to borrow from the Treasury of the United States, if necessary,
    amounts sufficient to make payments of principal and interest on the
    Ginnie Maes.

              Ginnie Maes.  Ginnie Maes are mortgage-backed securities of the
    "fully modified pass-through" type, the terms of which provide for timely
    monthly payments by the issuers to the registered holders of their pro
    rata shares of the scheduled principal payments, whether or not collected
    by the issuers, on account of the mortgages backing such Ginnie Maes, plus
    any prepayment of principal of such mortgages received, and interest (net
    of servicing and guarantee charges) on the aggregate unpaid principal
    balance of such Ginnie Maes, whether or not interest on account of such
    mortgages has been collected by the issuers.  Ginnie Maes will be
    guaranteed as to timely payment of principal and interest by GNMA.  The
    full faith and credit of the United States is pledged to the payment of
    all amounts which may be required to be paid under the guaranty.

              FNMA.  The Federal National Mortgage Association is a Federally
    chartered, privately-owned corporation organized and existing under the
    Federal National Mortgage Association Charter Act.  FNMA was originally
    established in 1938 as a United States government agency to provide
    supplemental liquidity to the mortgage market but was transformed into a
    stockholder owned and privately managed corporation by legislation enacted
    in 1968.  The Secretary of Housing and Urban Development exercises general
    regulatory power over FNMA.  FNMA nevertheless maintains certain
    relationships with the U.S. Government.  Although thirteen members of its
    board of directors are authorized to be elected by the shareholders, five
    are appointed by the President of the United States.  The President can
    also remove board members, including those elected by the shareholders. 
    Although the Secretary of the Treasury has discretionary authority to lend
    FNMA up to $2.25 billion outstanding at any time, neither the United
    States nor any agency thereof is obligated to finance FNMA's obligations
    or to assist FNMA in any other matter, and obligations issued by FNMA are
    not guaranteed by and do not constitute a debt or obligation of the United
    States or of any agency or instrumentality thereof other than FNMA.  FNMA
    provides funds to the mortgage market primarily by purchasing home
    mortgage loans from lenders, thereby replenishing funds for additional
    lending.  FNMA acquires funds to purchase home mortgage loans from many
    capital market investors which may not ordinarily invest in mortgages
    thereby expanding the total amount of funds available for housing.

              Fannie Maes.  Fannie Maes are certificates of beneficial
    interest evidencing pro rata undivided ownership interests in pools of
    residential mortgages either previously owned by FNMA or purchased by it
    in connection with the formation of a pool.  FNMA guarantees the full and
    timely payment of principal and interest (adjusted to the pass-through
    rate) on the mortgage loans in the pool, whether or not received by FNMA
    or recovered by it in foreclosure.  If FNMA were unable to fulfill its
    guaranty, distributions to holders of Fannie Maes would consist solely of
    payments and other recoveries upon the underlying mortgages, and,
    accordingly, delinquencies and default would diminish distributions to the
    holders.  The obligations of FNMA under its guaranty are solely those of
    FNMA and are not backed by the full faith and credit of the United States. 
    Moreover, neither the United States nor any of its agencies is obligated
    to finance the operations of FNMA or to assist it.

       
              FHLMC.  The Federal Home Loan Mortgage Corporation is a
    corporate instrumentality of the United States created pursuant to the
    Emergency Home Finance Act of 1970 (the "FHLMC Act").  FHLMC's common
    stock is owned by the Federal Home Loan Banks.  FHLMC was established
    primarily for the purpose of increasing the availability of mortgage
    credit for the financing of urgently needed housing.  It seeks to provide
    an enhanced degree of liquidity for residential mortgage investments
    primarily by assisting in the development of secondary markets for
    conventional mortgages.  The principal activity of FHLMC currently
    consists of the purchase of first lien, conventional residential mortgage
    loans or participation interests in such mortgage loans and the resale of
    the mortgage loans so purchased in the form of mortgage securities,
    primarily Freddie Macs.  All mortgage loans purchased by FHLMC must meet
    certain standards set forth in the FHLMC Act.  Mortgages retained by FHLMC
    are financed with debt and equity capital.

              Freddie Macs.  Freddie Macs represent an undivided interest in a
    pool of first lien, residential mortgages and mortgage participations
    ("Mortgages" or "PCs") purchased by FHLMC.  PCs include "Gold PCs,"
    "Original PCs," "ARM PCs," "Gold Giant PCs," "Original Giant PCs," and
    "ARM Giant PCs."  PCs may include whole loans, participation interests in
    whole loans and undivided interest in whole loans or participations
    comprising other PCs.  For example, Gold PCs, Original PCs and ARM PCs
    represent undivided interests in discrete pools consisting of Mortgages. 
    Gold Giant PCs, Original Giant PCs and ARM Giant PCs represent beneficial
    ownership interests in discrete pools consisting of PCs.  In the case of
    Original PCs FHLMC guarantees the timely payment of interest at the rate
    provided for by Freddie Macs on the unpaid principal balance outstanding
    on the underlying mortgage loans in the PCs represented by the Freddie
    Macs, whether or not received, and also guarantees collection of all
    principal on the underlying mortgage loans, without any offset or
    deduction, but does not guarantee the timely payment of scheduled
    principal.  Unlike Original PCs, Gold PCs guarantee the timely payment of
    both interest and scheduled principal, thus producing a more predictable
    payment stream.  Gold PCs also offer a shorter payment delay than that of
    conventional mortgage pass-through securities (FHLMC advances payment to
    Gold PC holders 14 days after the borrower's scheduled principal and
    interest payments are due), and a shorter period (approximately 45 days)
    between the first day of the month in which the Gold PCs are issued and
    the initial payment date.  Freddie Macs are not guaranteed by the United
    States or by any Federal Home Loan Bank and do not constitute debts or
    obligations of the United States or any Federal Home Loan Bank.  The
    obligations of FHLMC under its guarantee are obligations solely of FHLMC
    and are not backed by, nor entitled to, the full faith and credit of the
    United States.  If FHLMC were unable to fulfill its guaranty,
    distributions to holders of Freddie Macs would consist solely of payments
    and other recoveries upon the underlying mortgages, and, accordingly,
    delinquencies and defaults would diminish distributions to the holders.
        

    Special Features of Market Discount Securities

              Certain of the Securities in the Trusts may have been valued at
    a market discount.  Securities trade at less than par value because the
    interest rates on the Securities are lower than interest on comparable
    obligations being issued at currently prevailing interest rates.  The
    current returns of Securities trading at a market discount are lower than
    the current returns of comparably rated obligations of a similar type
    issued at currently prevailing interest rates because discount securities
    tend to increase in market value as they approach maturity and the full
    principal amount becomes payable.  If currently prevailing interest rates
    for newly issued and otherwise comparable securities increase, the market
    discount of previously issued securities will become deeper, and if
    currently prevailing interest rates for newly issued comparable securities
    decline, the market discount of previously issued securities will be
    reduced, other things, including, without limitation, credit quality and
    rate of prepayment, being equal.  Investors should also note that the
    value of the Securities valued at a market discount will increase faster
    than the Securities valued at a market premium if interest rates decrease. 
    Conversely, if interest rates increase, the value of the Securities valued
    at a market discount will decrease faster than the Securities valued at a
    premium.  In addition, if interest rates rise, the prepayment risk of
    higher yielding premium Securities, and the prepayment benefit for lower
    yielding, discount Securities will be reduced.  Market discount
    attributable to interest rate changes does not indicate a lack of market
    confidence in the issue.

    Special Features of Market Premium Securities

              Certain of the Securities in the Trusts may have been valued at
    a market premium.  Securities trade at a premium because the interest
    rates on the Securities are higher than interest on comparable obligations
    being issued at currently prevailing interest rates.  The current returns
    of Securities trading at a market premium are higher than the current
    returns of comparably rated obligations of a similar type issued at
    currently prevailing interest rates because premium securities tend to
    decrease in market value as they approach maturity when the principal
    amount becomes payable.  Because part of the purchase price is returned
    not at maturity but through current income payments, an early redemption
    of a premium security at par will result in a reduction in yield.  If
    currently prevailing interest rates for newly issued and otherwise
    comparable securities increase, the market premium of previously issued
    securities will decline and if currently prevailing interest rates for
    newly issued comparable securities decline the market premium of
    previously issued securities will increase, other things, including,
    without limitation, credit quality and rate of prepayment, being equal. 
    Market premium attributable to interest rate changes does not indicate
    market confidence in the issue.

              Neither the Sponsors nor the Trustee shall be liable in any way
    for any default, failure or defect in any of the Securities.  Because
    certain of the Securities 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 Trusts will retain their present size
    and composition for any length of time.  The proceeds from the sale of a
    Security or the exercise of any redemption or call provision will be
    distributed to Certificateholders except to the extent such proceeds are
    applied to meet redemptions of Units (see "Trustee Redemption").

    Liquidity

              The Securities in the Trusts have been registered, or are exempt
    from registration, under the Securities Act of 1933 and, therefore, may be
    sold by a Trust at any time to provide funds for purposes of redemption of
    Units. However, the Securities are generally not listed on a national
    securities exchange or on the National Association of Securities Dealers
    Automated Quotation System, Inc.  Whether or not the Securities are
    listed, the principal trading market for the Securities will generally be
    in the over-the-counter market.  As a result, the existence of a liquid
    trading market for the Securities may depend on whether dealers will make
    a market in the Securities.  There can be no assurance that a market will
    be made for any of the Securities, that any market for the Securities will
    be maintained or of the liquidity of the Securities in any markets made. 
    In addition, each Trust may be restricted under the Investment Company Act
    of 1940 from selling Securities to the Sponsors.  The price at which the
    Securities may be sold to meet redemptions and the value of the Trusts
    will be adversely affected if trading markets for the Securities are
    limited or absent.  However, taking into account the foregoing and other
    factors, the Sponsors believe that the nature of the GNMA, FNMA or FHLMC
    guarantees of any Securities that have been issued by them, respectively,
    and the nature of the Ginnie Maes, Fannie Maes or Freddie Macs security
    payments of principal and interest due on the Securities make the
    Securities adequately marketable for purposes of redemption of Units by
    the Trustee (see "Redemption").

    Limited Assets and Limited Liability

              Except as indicated under "Description of Portfolio" in Part A
    and except for any Securities that were issued by GNMA, FNMA or FHLMC, the
    issuers of the Securities are limited purpose corporations, trusts or
    other entities ("Limited Purpose Issuers"), organized solely for the
    purpose of issuing Ginnie Mae, Fannie Mae or Freddie Mac-collateralized
    CMOs.  None of the securities issued by the Limited Purpose Issuers
    (including the Securities deposited in the Trust) are guaranteed by the
    parent company or any other affiliate of any Limited Purpose Issuer. 
    Consequently, holders of these securities (including the Trust) must rely
    upon payments on the Ginnie Maes, Fannie Maes or Freddie Macs and upon any
    other collateral securing the securities (including the Securities
    deposited in the Trust) for the payment of principal and interest due on
    the Securities.  If the collateral securing the securities of each Limited
    Purpose Issuer is insufficient to make payments on those securities, it is
    unlikely that any other asset of the Limited Purpose Issuer will be
    available for payment of the deficiency.  The collateral securing the CMOs
    of each Issuer (including the Securities deposited in the Trust) will be
    held by the CMO Trustee as security for the CMOs of that Issuer.  Although
    payment of principal of and interest on Ginnie Maes, Fannie Maes and
    Freddie Macs securing the Securities is guaranteed by GNMA, FNMA and
    FHLMC, respectively, the CMOs (including the Securities deposited in the
    Trust except for any Securities which have been issued directly or
    indirectly by GNMA, FNMA or FHLMC) represent obligations solely of the
    Issuers and are not insured or guaranteed by GNMA, FNMA or FHLMC or any
    other governmental agency.  A default with respect to the securities of a
    particular Issuer (including the Securities of the Issuer deposited in the
    Trust) may not necessarily result from a corresponding default with
    respect to the underlying Ginnie Maes, Fannie Maes or Freddie Macs.

              For any Securities that have been issued by issuers other than
    GNMA, FNMA or FHLMC, the Sponsors have obtained representations from the
    issuer that it has received an opinion of counsel to the effect that it is
    not an investment company or that it has been exempted from the definition
    of an investment company by order of the Securities and Exchange
    Commission.  With respect to any Securities of issuers that have been
    exempted from the definition of an investment company by order of the
    Securities and Exchange Commission, the value of the Securities will not
    exceed more than 5% individually, or 10% in the aggregate, of the total
    value of the Securities in the Trust.

    Life of the Securities and of the Trusts

              CMOs are generally issued as a series of different classes.  An
    issue of CMOs tends to be backed by a larger number of mortgages than a
    pool of Ginnie Maes, Fannie Maes or Freddie Macs, thus allowing greater
    statistical prediction of prepayment characteristics.  Interest and
    principal payments on the mortgages underlying any series will first be
    applied to meet the interest payment requirements of each class in the
    series other than any class in respect of which interest accrues but is
    not paid or any principal only class.  Then, principal payments on the
    underlying mortgages are generally applied to pay the principal amount of
    the class that has the earliest maturity date.  Once that class is
    retired, the principal payments on the underlying mortgages are applied to
    the class with the next earliest maturity date.  This is repeated until
    all classes are paid.  Therefore, while each class of CMOs, remains
    subject to prepayment as the underlying mortgages prepay, structuring
    several classes of CMOs in the stream of principal payments allows a more
    predictable estimate of the period of time when any one class is likely to
    be repaid.  The estimate can be even closer with a class of planned
    amortization bonds or targeted amortization bonds.  The amortization
    schedule for these CMOs is structured so that, at specified prepayment
    rates within a relatively wide range, their principal will be repaid at
    specified times and in specified amounts.  However, if any series of CMOs
    contains a class of planned amortization bonds or targeted amortization
    bonds, then the other classes in that series may not be retired in an
    order of priority determined strictly with reference to their maturity
    dates.  These other classes are often referred to as "support classes"
    because their function is to support the amortization schedule of the
    planned amortization bonds or targeted amortization bonds.  If the rate of
    prepayments on the underlying mortgages is faster than assumed, then
    classes with maturity dates later than the planned amortization bonds or
    targeted amortization bonds may be retired earlier than estimated to
    ensure that the planned amortization bonds or targeted amortization bonds
    receive the principal payments required by their amortization schedule. 
    Similarly, if the rate of prepayments is slower than anticipated, earlier
    support classes may be retired later than estimated.  Hence, support
    classes of a series that contains planned amortization bonds or targeted
    amortization bonds have less predictable prepayment characteristics than
    classes of a series that does not.  This lack of predictability regarding
    prepayments also causes support class bonds to have greater market value
    fluctuation than other classes of a CMO and causes fluctuation, which may
    be substantial, both in the amount of income earned by the Long-
    Intermediate Portfolio and in the timing of the Long-Intermediate
    Portfolio's principal distributions.  This fluctuation may adversely
    affect the repurchase and redemption prices of Units of the Long-
    Intermediate Portfolio (see "Description of Portfolios" in each Part A for
    the number of planned amortization bonds, target amortization bonds and
    support bonds contained in the Trust portfolios).  The rate of prepayment
    on the underlying mortgages of a CMO will most likely decline as interest
    rates increase.  If the rate of prepayment declines, the weighted average
    life of the support class bonds will most likely increase and, in some
    cases, the decline will impact the yield and market value of these
    Securities.  This may cause an investor's principal in a support class
    bond to be outstanding for a longer period of time than initially
    anticipated.  Conversely, if interest rates decline, prepayments on the
    underlying mortgages will most likely increase, and the weighted average
    life of the support class bonds may be shorter than anticipated.  A holder
    of a support class bond in these situations may be unable to reinvest the
    proceeds of these principal distributions at an effective interest rate
    equal to the specified coupon rate on the original support class bond. 
    Therefore, an investor expecting to earn a fixed return for a fixed number
    of years may find the life of a support class investment decreases as
    interest rates fall and increases as they rise.

       
              In contrast, Ginnie Maes, Fannie Maes or Freddie Macs,
    estimation of repayment is more difficult as the cash flow on the
    underlying mortgages is simply passed through on a pro rata basis to the
    holders.  However, any estimate of the prepayment period for any class of
    CMO is based upon certain assumptions as to the prepayment speed of the
    underlying mortgages, which assumptions may prove to be inaccurate over
    time.  See "Estimated Long Term Return and Estimated Current Return."
        

              All of the mortgages in the pools relating to the Ginnie Maes,
    Fannie Maes or Freddie Macs backing the Securities in the Trust are
    subject to prepayment without any significant premium or penalty at the
    option of the mortgagors (i.e., the homeowners).  Because certain of the
    Securities from time to time may be redeemed or prepaid or will mature in
    accordance with their terms or may be sold under certain circumstances
    described herein, no assurance can be given that the Trust will retain for
    any length of time its present size and composition (see "Redemption").

              While the mortgages on the 1 to 4 family dwellings underlying
    Ginnie Maes, Fannie Maes or Freddie Macs which may back the Securities are
    amortized over a period of up to 30 years, it has been the experience of
    the mortgage industry that the average life of comparable mortgages, owing
    to prepayments, is considerably less.  Prepayments on mortgages are
    commonly measured relative to a prepayment standard or model.  The
    prepayment model of the Public Securities Association (the "Prepayment
    Model") represents an assumed rate of prepayment each month relative to
    the then outstanding principal balance of a pool of new mortgage loans. 
    100% of the Prepayment Model assumes prepayment rates of 0.2% per annum of
    the then outstanding principal balance of such mortgage loans in the first
    month of the life of the mortgage loans and an additional 0.2% per annum
    in each month thereafter until the 30th month.  Beginning in the 30th
    month and in each month thereafter during the life of the mortgage loans,
    100% of the Prepayment Model assumes a constant prepayment rate of 6% per
    annum.  The principal repayment behavior of any individual mortgage will
    likely vary from these assumptions.  The extent of this variation will
    depend on a variety of factors, including the relationship between the
    coupon rate on a mortgage and prevailing mortgage origination rates.  As
    prevailing mortgage origination rates increase in relationship to a
    mortgage coupon rate, the likelihood of prepayment of that mortgage
    decreases.  Conversely, during periods in which prevailing mortgage
    origination rates are significantly less than a mortgage coupon rate,
    prepayment of that mortgage becomes increasingly likely.  Research
    analysts use complex formulae to scrutinize the prepayments of mortgage
    pools in an attempt to predict more accurately the average life of any
    particular class of mortgage-backed bonds.  The basis for the calculation
    of estimated average life and the relationship of this calculation for
    Estimated Long Term Return is more fully described under "Estimated Long
    Term Return and Estimated Current Return."

              Generally speaking, a number of factors, including mortgage
    market interest rates and homeowners' mobility, will affect the average
    life of the Ginnie Maes, Fannie Maes or Freddie Macs which back the
    Securities in the Trusts and, accordingly, there can be no assurance that
    the prepayment levels which will be actually realized will conform to the
    estimated levels.  Changes in prepayment patterns, as reported by each of
    GNMA, FNMA and FHLMC on a periodic basis, if generally applicable to the
    mortgage pools related to specific CMOs could influence yield assumptions
    used in pricing the securities.  Shifts in prepayment patterns are
    influenced by changes in housing cycles and mortgage refinancing and are
    also subject to certain limitations on the gathering of the data; it is
    impossible to predict how new statistics will affect the yield assumptions
    that determine mortgage industry rooms and pricing of CMOs.  Moreover,
    there is no assurance that the pools of mortgage loans relating to the
    Securities in the Trust will conform to prepayment experience as reported
    by GNMA, FNMA or FHLMC on a periodic basis or the prepayment experience of
    other mortgage lenders.

              While the value of CMOs generally fluctuates inversely with
    changes in interest rates, it should also be noted that the potential for
    appreciation on CMOs, which could otherwise be expected to result from a
    decline in interest rates, may tend to be limited by any increased
    prepayments by mortgagors as interest rates decline (except for Principal
    Only Bonds whose yield increases with the speed at which payments of
    principal are received at par).  Accordingly, the termination of the
    Trusts might be accelerated as a result of prepayments made as described
    above.  In addition, it is possible that, in the absence of a secondary
    market for the Units or otherwise, redemption of Units may occur in
    sufficient numbers to reduce a Portfolio to a size resulting in the
    termination of the Trust (termination for this reason would be delayed if
    additional Units are issued).  Early termination of a Trust may have
    important consequences to Certificateholders, e.g., the extent that Units
    were purchased with a view to an investment of longer duration, the
    overall investment program of the investor may require readjustment, or
    the overall return on investment may be less or greater than anticipated,
    depending in part on whether the purchase price paid for Units represented
    the payment of an overall premium or a discount, respectively, above or
    below the stated principal amounts of the underlying mortgages.


                                  PUBLIC OFFERING

    Offering Price

              The secondary market Public Offering Price per 1,000 Units of
    the Trust is computed by adding to the aggregate bid price of the
    Securities in the Trust divided by the number of Units outstanding times
    1,000, an amount equal to (a) for the Short-Intermediate Portfolio, 3.627%
    of the aggregate bid price of the Securities per 1,000 Units which is
    equal to 3.5% of the Public Offering Price per 1,000 Units, (b) for the
    Intermediate Portfolio, 3.896% of the aggregate bid price of the
    Securities per 1,000 Units which is 3.75% of the Public Offering Price per
    1,000 Units and (c) for the Long-Intermediate Portfolio, 4.167% of the
    aggregate offering price of the Securities per 1,000 Units which is equal
    to 4% of the Public Offering Price per 1,000 Units.  A proportionate share
    of accrued interest on the Securities is added to the Public Offering
    Price.  Accrued interest is the accumulated and unpaid interest on
    Securities 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.  The Public Offering Price can vary
    on a daily basis from the amount stated in this Prospectus in accordance
    with fluctuations in the prices of the Securities and the price to be paid
    by each investor will be computed as of the date the Units are purchased. 
    The aggregate bid price evaluation of the Bonds is determined in the
    manner set forth under "Trustee Redemption."

              The Evaluator may obtain current bid or offering prices for the
    Securities from investment dealers or brokers (including the Sponsors)
    that customarily deal in CMOs or from any other report service or source
    of information which the Evaluator deems appropriate.

    Accrued Interest

              Accrued interest is the accumulation of unpaid interest on a
    Security from the last day on which interest thereon was paid.  Interest
    on Securities in the Trusts is actually paid monthly to the Trusts. 
    However, interest on Securities in each Trust is accounted for daily on an
    accrual basis.  Because of this, a Trust always has an amount of interest
    earned but not yet collected by the Trustee because of non-collected
    coupons.  For this reason, the Public Offering Price of Units will have
    added to it the proportionate share of accrued and undistributed interest
    to Date of Settlement.

              A Certificateholder will not recover his proportionate share of
    accrued interest until the Units are sold or redeemed, or the Trust is
    terminated.  At that time, the Certificateholder will receive 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.

    Distribution of Units

              Certain banks and thrifts will make Units of the Trust available
    to their customers on an agency basis.  A portion of the sales charge paid
    by their customers is retained by or remitted to the banks.  Under the
    Glass-Steagall Act, banks are prohibited from underwriting Units; however,
    the Glass-Steagall Act does permit certain agency transactions and the
    banking regulators have indicated that these particular agency
    transactions are permitted under such Act.  In addition, state securities
    laws on this issue may differ from the interpretations of federal law
    expressed herein and banks and financial institutions may be required to
    register as dealers pursuant to state law.

              The Sponsors intend to qualify the Units for sale in
    substantially all States through the Underwriters and 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 up to $25
    per 1,000 Units, subject to the Sponsors' right to change the dealers'
    concession from time to time.  In addition, for transactions of 1,000,000
    Units or more, the Sponsors intend to negotiate the applicable sales
    charge and such charge will be disclosed to any such purchaser.  Such
    Units may then be distributed to the public by the dealers at the Public
    Offering Price then in effect.  The Sponsors reserve the right to reject,
    in whole or in part, any order for the purchase of Units.  The Sponsors
    reserve the right to change the discounts from time to time.

    Sponsors' and Underwriters' Profits

              The Sponsors will receive a gross commission equal to (a) for
    the Short-Intermediate Portfolio, 3.5% of the Public Offering Price per
    1,000 Units (equivalent to 3.627% of the net amount invested in the
    Securities), (b) for the Intermediate Portfolio, 3.75% of the Public
    Offering Price per 1,000 Units (equivalent to 3.896% of the net amount
    invested in the Securities) and (c) for the Long-Intermediate Portfolio,
    4% of the Public Offering Price per 1,000 Units (equivalent to 4.167% of
    the net amount invested in the Securities).  In addition, in maintaining a
    market for the Units (see "Sponsors Repurchase") the Sponsors will realize
    profits or sustain losses in the amount of any difference between the
    price at which they buy Units and the price at which they resell 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, Sponsors' 
    Repurchase Price and Redemption Price         
        
              The secondary market Public Offering Price of the Units will be
    determined on the basis of the current bid prices of the Securities in the
    Trusts, plus the applicable sale charges.  The value at which Units may be
    resold in the secondary market will be determined on the basis of the
    aggregate bid side evaluation of the Securities.  On the Evaluation Date,
    the Public Offering Price per 1,000 Units and the Sponsors' Repurchase
    Price per 1,000 Units (each based on the bid side evaluation of the
    Securities) each exceeded the Redemption Price per 1,000 Units and the
    Sponsors' secondary market Repurchase Price per 1,000 Units (based on the
    current bid side evaluation of the Securities) by the amounts shown under
    "Summary of Essential Information" in Part A.


              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" as described below.

              The Estimated Net Annual Interest Income per 1,000 Units for the
    Trust, set forth under "Summary of Essential Information", shows the
    return based on $1.00 principal amount per Unit after deducting estimated
    annual fees and expenses.  This figure will change as Securities mature,
    are prepaid, exchanged, redeemed, pair or sold, as replacements or
    Additional Securities are purchased and deposited in the Trust or as the
    expenses of the Trust change. 

              In actual operation, payments received in respect of the
    mortgages underlying the Ginnie Maes, Fannie Maes or Freddie Macs which in
    turn back the Securities will consist of a portion representing interest
    and a portion representing principal.  Although the aggregate monthly
    payment made by the obligor on each mortgage remains constant (aside from
    optional prepayments of principal), in the early years the larger
    proportion of each payment will represent interest, while in later years,
    the proportion representing interest will decline and the proportion
    representing principal will increase, although the interest rate remains
    constant.  Moreover, by reason of optional prepayments, payments in the
    earlier years on mortgages may be substantially in excess of those
    required by the amortization schedules of these mortgages; conversely,
    payments in later years may be substantially less since the aggregate
    unpaid principal balances of the underlying mortgages and, hence, the
    related Ginnie Maes, Fannie Maes or Freddie Macs may have been greatly
    reduced--ultimately even sufficiently reduced to accelerate termination of
    the Trust.  To the extent that those Securities bearing the higher
    interest rate represented in the Portfolio are prepaid faster than other
    Securities, the net annual interest per 1,000 Units and the return on the
    Units can be expected to decline.  Monthly payments to the
    Certificateholders will reflect all of the foregoing factors.

              Interest on the Securities in the Trusts, less estimated fees of
    the Trustee and Sponsors and certain other expenses, is expected to accrue
    per 1,000 Units at the daily rate (based on a 360-day year) shown under
    "Summary of Essential Information".  The actual daily rate will vary as
    Securities are prepaid, exchanged, redeemed, paid or sold or as the
    expenses of the Trust change.

              The Estimated Current Return and the Estimated Long Term Return
    for each Trust on the Evaluation Date are set forth under "Summary of
    Essential Information" in Part A.  Estimated Long Term Return is
    calculated by:  (1) computing the yield to maturity for each CMO in the
    Trust's portfolio in accordance with accepted CMO practices, which
    practices take into account not only the interest payable on the CMO but
    also the amortization of premiums or accretion of discounts, if any, and
    estimated appropriate prepayments; (2) calculating the average of yields
    for the CMOs in the Trust's portfolio by weighing each CMOs' yield by the
    market value of the CMO and by the amount of time remaining to the date to
    which the CMO 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 Certificateholders.  The resulting Estimated
    Long Term Return represents a measure of the return to Certificateholders
    earned over the estimated life of the Trust.

              Estimated Current Return for each Portfolio is computed by
    dividing the Estimated Net Annual Interest Income per 1,000 Units by the
    Public Offering Price per 1,000 Units.  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 CMOs in
    the portfolio of the Trust.

              The calculation of an estimated average life for any Security in
    the Trusts is a two stage process.  First, several assumptions are made to
    derive an estimated prepayment rate for the mortgages underlying the
    Ginnie Maes, Fannie Maes or Freddie Macs which back the Securities.  Based
    upon historical prepayment data provided by GNMA, FNMA or FHLMC an
    assumption is made as to how the prepayment behavior of the mortgages will
    be affected as they amortize.  However, because historical prepayment data
    afford only a limited basis upon which to analyze prepayment behavior, the
    Sponsors have developed an econometric model that allows an analysis of
    several other important variables.  The principal variables are the spread
    between present market interest rates and the interest rate on the
    mortgages and the turnover rate in the housing market.  Finally, the
    Sponsors use this model's prepayment predictions to derive an estimated
    prepayment rate for the mortgage pool, expressed in terms of the PSA
    Prepayment Model, from which an estimated average life an estimated
    prepayment schedule can be projected for the Ginnie Maes, Fannie Maes or
    Freddie Macs themselves.  While the various estimates made in this first
    stage are subjected to rigorous analysis, investors should be aware that
    they are based upon reported statistical relations that may not remain
    constant and assumptions about the future of an uncertain economic
    environment.

              The second stage in determining the estimated average life of
    any Security in the Trusts involves the use of a formula to apply the
    estimated rate of principal payments on the mortgage pool to amortize the
    Ginnie Maes, Fannie Maes or Freddie Macs which back the Securities and to
    retire the principal amount of each CMO class of the same series,
    including the Security itself, according to the specific principal
    reduction schedule of that series.  This results in an estimate of the
    point at which the principal of any Security will begin to be paid and how
    long it will take for the principal to be fully paid.  If any Security was
    issued in a series that contains planned amortization bonds or targeted
    amortization bonds, then the estimated rate of principal payments on the
    underlying mortgages will be applied to the other classes in that series
    in a manner that takes account of the amortization schedule of the planned
    amortization bonds or targeted amortization bonds.  This results in less
    predictable prepayment characteristics for those other classes.  The
    estimated average life for the Trust provided under the "Summary of
    Essential Information" is subject to change with alterations in the data
    used in any of the underlying assumptions.  The actual average lives of
    the Securities and the actual long term returns will be different from the
    estimated average lives and the Estimated Long Term Returns.

              Both Estimated Current Return and Estimated Long Term Return are
    subject to fluctuation with changes in Portfolio composition, principal
    payments and prepayments and changes in market value of the underlying
    Securities and changes in fees and expenses, including sales charges, and
    therefore can be materially different than the figures set forth under the
    Summary of Essential Information.  The size of any difference between
    Estimated Current Return and Estimated Long Term Return can also be
    expected to fluctuate at least as frequently.  In addition, both return
    figures may not be directly comparable to yield figures used to measure
    other investments, and since the return figures are based on certain
    assumptions and variables the actual returns received by a
    Certificateholder may be higher or lower.  The Estimated Long Term Return
    and Estimated Current Return calculations do not take into account certain
    delays in distributions of income and the timing of other receipts and
    distributions on Units and may, depending on maturities, over or
    understate the impact of sales charges.  Both of these factors may result
    in lower figures.

              In addition to the Public Offering Price, the price of a Unit
    includes accrued interest on the Securities.  Securities deposited in the
    Trust include an item of accrued but unpaid interest up to the date of
    delivery of the Securities.  Certificateholders pay for this additional
    accrued interest when they purchase Units.  In addition, interest accruing
    after the date of delivery of the Securities is added to the Public
    Offering Price.  Accrued interest earns no return.

              The payment dates of the Securities may vary and therefore
    accrued interest at any time may be greater than the amount of interest
    actually received by the Trust and distributed to Certificateholders. 
    Therefore, accrued interest (if any) is always added to the value of the
    Units.  If a Certificateholder sells all or a portion of his Units, he
    will receive his proportionate share of the accrued interest from the
    purchaser of his Units.  Similarly, if a Certificateholder redeems all or
    a portion of his Units, the Redemption Price per Unit will include accrued
    interest on the Securities.


                           RIGHTS OF CERTIFICATEHOLDERS

    Certificates

              Ownership of Units of the Trust is evidenced by registered
    Certificates executed by the Trustee and the Sponsors.  Certificates may
    be issued in denominations of one thousand or more Units.  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 each Trust is credited by the Trustee to an
    Interest Account for the Trust.  Proceeds representing principal received
    from the maturity, redemption, sale or other disposition of the Securities
    are credited to the Principal Account of the Trust.

              Distributions to each Certificateholder from the Interest
    Account are computed as of the close of business on each Record Date for
    the following Payment Date and consist of an amount substantially equal to
    such Certificateholder's pro rata share of the amount of interest received
    on the Securities during such month in the Interest Account less amounts
    deducted or estimated to be deducted as discussed below.  Distributions
    from the Principal Account of each Trust (other than amount representing
    failed contracts, as previously discussed) will be computed as of each
    monthly Record Date, and will be made to the Certificateholders of that
    Trust on the next monthly Payment Date.  Proceeds representing principal
    received from the disposition of any of the Securities between a Record
    Date and a Payment Date which are not used for redemptions of Units will
    be held in the Principal Account and not distributed until the second
    succeeding monthly Payment Date.  No distributions will be made to
    Certificateholders electing to participate in the Total Reinvestment Plan. 
    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.  All funds in respect of the Securities received and held by the
    Trustee prior to distribution to Certificateholders may be of benefit to
    the Trustee and do not bear interest to Certificateholders.

              As of the first day of each month, the Trustee will deduct from
    the Interest Account of each Trust, and, to the extent funds are not
    sufficient therein, from the Principal Account of the Trust, amounts
    necessary to pay the expenses of the Trust (as determined on the basis set
    forth under "Trust Expenses and Charges").  The Trustee also may withdraw
    from said accounts such amounts, if any, as it deems 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 Trustee
    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 purchases of
    Replacement Securities and redemptions of Units by the Trustee.

              The estimated monthly distribution per 1,000 Units will be in
    the approximate amount shown under "Summary of Essential Information" in
    Part A and will change and may be reduced as Securities are prepaid 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 per 1,000 Units.

    Records

              The Trustee shall furnish Certificateholders in connection with
    each distribution a statement of the amount of interest, if any, and the
    amount of the receipts, if any, which are being distributed, expressed in
    each case as a dollar amount per 1,000 Units.  Within a reasonable time
    after the end of each calendar 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, amounts paid for purchases of Replacement Securities and
    redemptions of Units, if any, deductions for applicable taxes and 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 1,000 Units outstanding on
    the last business day of such calendar year; (b) as to the Principal
    Amount:  the dates of disposition of any Securities and the net proceeds
    received therefrom, deductions for payments of applicable taxes and fees
    and expenses of the Trust, amounts paid for purchases of Replacement
    Securities and 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
    1,000 Units outstanding on the last business day of such calendar year;
    (c) a list of the Securities held and the number of Units outstanding on
    the last business day of such calendar year; (d) the Redemption Price per
    1,000 Units based upon the last computation thereof made during such
    calendar year; and (e) amounts actually distributed to Certificateholders
    during such calendar year from the Interest and Principal Accounts,
    separately stated, of the Trust, expressed both as total dollar amounts
    and as dollar amounts representing the pro rata share of each 1,000 Units
    outstanding on the last business day of such calendar year.

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

                                    TAX STATUS

              The Sponsors believe that (i) each Security the interest on
    which is United States source income (which is the case for most
    Securities issued by United States issuers) was or will have been issued
    after July 18, 1984, (ii) each Security is a regular interest in a REMIC,
    as defined in Sections 860A-G of the Code, and (iii) interest on any
    Security issued by a non-United States issuer is not subject to any
    foreign withholding taxes under current law.  There can be no assurance,
    however, that foreign withholding taxes will not be imposed on interest on
    Securities issued by non-United States issuers in the future.

              Neither the Sponsors nor Battle Fowler has made or will make a
    review of the facts and circumstances relating to the issuance of any
    Security.

              Based on the foregoing, in the opinion of Battle Fowler, special
    counsel for the Sponsors, under existing law:

              The Trusts are not associations taxable as a corporation for
         Federal income tax purposes, and income received by each Trust will
         be treated as the income of the Certificateholder in the manner set
         forth below.

              Each Certificateholder will be considered the owner of a pro
         rata portion of each Security in the Trust under the grantor trust
         rules of Sections 671-679 of the Internal Revenue Code of 1986, as
         amended (the "Code").  In order to determine the face amount of the
         Certificateholder's pro rata portion of each Security on the initial
         Date of Deposit, see Principal Amount of Securities under
         "Portfolio."  The total cost to a Certificateholder of his Units,
         including sales charges, is allocated among his or her pro rata
         portion of each Security (in proportion to the fair market values
         thereof on the date the Certificateholder purchases his Units) in
         order to determine his tax cost for his pro rata portion of each
         Security.  In order for a Certificateholder who purchases his Units
         on the initial Date of Deposit to determine the fair market value of
         his pro rata portion of each Security on such date, see Cost of
         Securities to Trust under "Portfolio."

              A Certificateholder will be required to include in income his or
         her respective pro rata share of interest on each Security (whether
         or not the Security has original issue discount, as discussed below)
         as interest accrues, whether or not the Certificateholder is an
         accrual method taxpayer.  An individual Certificateholder who
         itemizes deductions may deduct his pro rata share of fees and
         expenses of the Trust only to the extent that such amount together
         with the Certificateholder's other miscellaneous deductions exceeds
         2% of his adjusted gross income and subject to overall restrictions
         on itemized deductions set forth in Section 68 of the Code.

              The Trusts may contain Securities which were originally issued
         at a discount ("original issue discount").  In general, original
         issue discount is defined as the difference between the price at
         which a security was issued and its stated redemption price at
         maturity.  Original issue discount on a Security will accrue as
         interest over the life of the Security under a formula based on the
         compounding of interest.  Such formula requires the adoption by the
         issuer of the Securities of certain prepayment assumptions, discussed
         in more detail in "Estimated Long Term Return and Estimated Current
         Return."  Certificateholders are urged to consult their own tax
         advisers.  In the case of a Certificateholder who purchases Units in
         a trust holding a  Security that was originally issued at a discount,
         the amount of original issue discount that will accrue will be
         reduced if the Certificateholder purchases the Units at a price that
         reflects a lower yield for the Security than the yield thereon at the
         time of the original issuance of such Security.  Each
         Certificateholder will be required to include in income in each year
         the amount of original issue discount which accrues during the year
         on his pro rata portion of any Security originally issued at a
         discount.  The amount of original issue discount so included in
         income in respect of a Certificateholder's pro rata portion of a
         Security is added to the Certificateholder's tax cost therefor.

              If a Certificateholder's tax cost for his pro rata portion of a
         Security exceeds the redemption price at maturity thereof, the
         Certificateholder will be considered to have purchased his pro rata
         portion of the Security at a "premium."  The Certificateholder
         (except in the case of a dealer in securities or one who holds debt
         obligations primarily for sale to customers in the ordinary course of
         his trade or business) may elect to amortize the premium prior to the
         maturity of the Security.  The amount amortized in any year should be
         applied to offset the Certificateholder's interest from the Security
         and should result in an adjustment to basis (i.e., a reduction of the
         Certificateholder's tax cost) for his pro rata portion of the
         Security.

              A Certificateholder will recognize taxable gain or loss when all
         or part of his pro rata portion of a Security is disposed of for an
         amount greater or less than his original tax cost therefor plus any
         accrued original issue discount or minus any amortized premium.  Any
         such taxable gain or loss will be capital gain or loss, except in the
         case of a dealer, and except as provided for in the next paragraph.

              Any gain from the disposition of a Certificateholder's pro rata
         portion of a Security issued after July 18, 1984 and acquired by the
         Certificateholder at "market discount" (i.e., if the
         Certificateholder's original cost for his pro rata portion of the
         Security (plus any original issue discount which has accrued thereon)
         is less than its stated redemption price at maturity) will be treated
         as ordinary income to the extent the gain does not exceed the accrued
         market discount.  The deduction of capital losses is subject to
         limitations.  A Certificateholder will be considered to have disposed
         of all or part of his pro rata portion of each Security when he sells
         or redeems all or some of his Units.  A Certificateholder will also
         be considered to have disposed of all or part of his pro rata portion
         of a Security when all or part of the Security is sold by the Trust
         or is redeemed or paid at maturity.

              Units that are owned by Certificateholders, other than a dealer
         in securities or one who holds debt obligations primarily for sale to
         customers in the ordinary course of his trade or business, are
         capital assets and generally produce capital gains and losses upon
         their sale or disposition.  Gain realized upon the sale or
         disposition of an interest in a REMIC, however, will be ordinary
         income to the extent of unaccrued original issue discount as
         determined by a prescribed formula.

              Under the income tax laws of the State and City of New York, the
         Trust is not an association taxable as a corporation and income
         received by the Trust will be treated as the income of the
         Certificateholders in the same manner as for Federal income tax
         purposes. 

              Notwithstanding the foregoing, a Certificateholder who is not a
         citizen or resident of the United States or a United States domestic
         corporation (a "Foreign Certificateholder") will generally not be
         subject to United States Federal income taxes, including withholding
         taxes, or information reporting, on the interest income (including
         any original issue discount) on, or any gain from the sale or other
         disposition of, his pro rata portion of any Security provided that
         (i) the interest income or gain is not effectively connected with the
         conduct by the Foreign Certificateholder of a trade or business
         within the United States, (ii) if the interest is United States
         source income (which is the case on most Securities issued by United
         States issuers), the Security is issued after July 18, 1984 and the
         Foreign Certificateholder does not own, actually or constructively,
         10% or more of the total combined voting power of all classes of
         voting stock of the issuer of the Security and is not a controlled
         foreign corporation related (within the meaning of Section 864(d)(4)
         of the Code) to the issuer of the Security, (iii) with respect to any
         gain, the Foreign Certificateholder (if an individual) is not present
         in the United States for 183 days or more during the taxable year and
         does not have a "tax home" (as defined in Section 911(d)(3) of the
         Code) in the United States, and the gain is not attributable to an
         office or fixed place of business maintained by such individual in
         the United States, and (iv) the Foreign Certificateholder provides
         the required certification of his status and of the matters contained
         in clauses (i), (ii) and (iii) above.  Foreign Certificateholders
         should consult their own tax advisers with respect to United States
         Federal income tax consequences of ownership of Units.

              After the end of each calendar year, the Trustee will furnish to
    each Certificateholder an annual statement containing information relating
    to the interest received by the Trust on the Securities, the gross
    proceeds received by the Trusts from the disposition of any Security
    (resulting from redemption or payment at maturity of any Security or the
    sale by the Trust of any Security), and the fees and expenses paid by the
    Trusts.  The Trustee will also furnish annual information returns to each
    Certificateholder and to the Internal Revenue Service.

              The foregoing discussion relates only to United States Federal
    and, to a limited extent, New York State and City income taxes. 
    Certificateholders may be subject to taxation in New York or in other
    jurisdictions (including a Foreign Certificateholder's country of
    residence) and should consult their own tax advisers in this regard.

    Tax-Exempt Investors

              Entities that generally qualify for an exemption from federal
    income tax, such as many pension trusts, are nevertheless taxed under
    Section 511 of the Code on "unrelated business taxable income."  Unrelated
    business taxable income is income from a trade or business regularly
    carried on by the tax-exempt entity that is unrelated to the entity's
    exempt purpose.  Unrelated  business taxable income generally does not
    include interest income or gain from the sale of investment property,
    unless such income is derived from property that is debt-financed or such
    gain is derived from property that is dealer property.  A tax-exempt
    entity's interest income from the Trust and gain from the sale of Units in
    the Trust or the Trust's sale of Securities is not expected to constitute
    unrelated business income to such tax-exempt entity unless the acquisition
    of the Unit itself is debt-financed or constitutes dealer property in the
    hands of the tax-exempt entity.

              Before investing the Trust, the trustee or investment manager of
    an employee benefit plan (e.g., a pension or profit sharing retirement
    plan) should consider among other things (i) whether the investment is
    prudent under ERISA, taking into account the needs of the plan and all of
    the facts and circumstances of the investment in the Trust; (ii) whether
    the investment satisfies the diversification requirement of Section
    404(a)(1)(C) of ERISA; and (iii) whether the assets of the Trust are
    deemed "plans assets" under ERISA and the Department of Labor regulations
    regarding the definition of "plan assets."

              Prospective tax-exempt investors are urged to consult their own
    advisors prior to investing in the Trust.


                                     LIQUIDITY

    Sponsors Repurchase

              The Sponsors, although not obligated to do so, intend to
    maintain a secondary market for the Units and continuously to offer to
    repurchase the Units.  The Sponsors' secondary market repurchase price
    after the initial public offering is completed will be based on the
    aggregate bid price of the Securities in each Trust and will be the same
    as the redemption price.  The aggregate bid price will be determined by
    the Evaluator on a daily basis after the initial public offering is
    completed and computed on the basis set forth under "Trustee Redemption". 
    Certificateholders who wish to dispose of their Units should inquire of
    the Sponsors as to current market prices prior to making a tender for
    redemption.  The Sponsors may discontinue repurchase 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 Bear, Stearns & Co. Inc.,
    245 Park Avenue, New York, New York 10167, on behalf of the Sponsors. 
    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.

              Units purchased by the Sponsors in the secondary market may be
    reoffered for sale by the Sponsors at a price based on the aggregate bid
    price of the Securities in the Trust plus (a) for the Short-Intermediate
    Portfolio, a 3.5% sales charge (3.627% of the net amount invested) plus
    net accrued interest, (b) for the Intermediate Portfolio, a 3.75% sales
    charge (3.896% of the net amount invested) plus net accrued interest and
    (c) for the Long-Intermediate Portfolio, a 4% Sales Charge (4.167% of the
    net amount invested) plus net accrued interest.  Any Units that are
    purchased by the Sponsors in the secondary market also may be redeemed by
    the Sponsors if it determines such redemption to be in its best interest.

              The Sponsors may, under certain circumstances, as a service to
    Certificateholders, elect to purchase any Units tendered to the Trustee
    for redemption (see "Trust Redemption").  Factors which the Sponsors will
    consider in making a determination will include the number of Units of all
    Trusts which it has in inventory, its estimate of the salability and the
    time required to sell such Units and general market conditions.  For
    example, if in order to meet redemption of Units the Trustee must dispose
    of Securities, and if such disposition cannot be made by the redemption
    date (seven calendar days after render), the Sponsors 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 redemption
    date of an amount equal to the Redemption Price on the date of tender. 

    Trustee Redemption

              Units may also be tendered to the Trustee for redemption at its
    corporate trust office at 770 Broadway, New York, New York 10003, 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
    Sponsors or the Trustee.  Units redeemed by the Trustee will be canceled.

              Certificate 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, redemptions 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.

              Within seven calendar days following a tender for redemption,
    or, if such seventh 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 Replacement Price per Unit
    computed as of the Evaluation Time set forth under "Summary of Essential
    Information" in Part A 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
    Securities in order to make funds available for redemptions.  Such sales,
    if required, could result in a sale of Securities by the Trustee at a
    loss.  To the extent Securities 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 a 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 Securities in the Trust based on the bid prices of such Securities
    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 the distribution to
    Certificateholders of record as of the business day prior to the
    evaluation being made.  The Evaluator may determine the value of the
    Securities in the Trust (i) if the Securities are listed on a national
    securities exchange (CMOs are usually not so listed), based on the closing
    sale prices on that exchange (unless the Evaluator deems these prices
    inappropriate as a basis for valuation), (ii) if the Securities are not so
    listed or, if so listed and the principal market therefor is other than on
    the exchange or there are no closing sale prices on the exchange, based on
    the closing sale prices on the over-the-counter market (unless the
    Evaluator deems these prices inappropriate as a basis for evaluation),
    (iii) if closing sale prices are unavailable, (a) on the basis of current
    bid or offering prices for the Securities, (b) if bid or offering prices
    are not available for any Securities, on the basis of current bid or
    offering prices for comparable securities, (c) by appraising the value of
    the Securities on the bid or offering side of the market or (d) by any
    combination of the above.  The Evaluator may obtain current price
    information as to the Securities from investment dealers or brokers
    (including the Sponsors) which customarily deal in this type of security.

              While the Sponsors believe that Securities of the type included
    in the Trusts involve minimal risk of loss of principal, due to variations
    in interest rates the market value of these Securities, and Redemption
    Price per Unit (particularly of the Long-Intermediate Portfolio), can be
    expected to fluctuate during the period of an investment in the Trusts.

              The Trustee is irrevocably authorized in its discretion, if the
    Sponsors do not elect to purchase a Unit tendered for redemption or if the
    Sponsors tender 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 prices which will return to the
    Certificateholder 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 Bonds is not reasonably practicable, or for such
    other periods as the Securities and Exchange Commission may by order
    permit.  The Trustee and the Sponsors 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
       
              Distributions of interest and principal, if any, from the Trusts
    are made to Certificateholders monthly.  The Certificateholder has the
    option, however, of either receiving his interest check, together with any
    principal payments, from the Trustee or participating in a reinvestment
    program offered by the Sponsors in shares of The Treasurer's Fund, Inc.,
    U.S. Treasury Money Market Portfolio (the "Fund").  Participation in the
    reinvestment option is conditioned on the Fund's lawful qualification for
    sale in the state in which the Certificateholder is a resident. 
        

              Upon enrollment in the reinvestment option, the Trustee will
    direct interest and/or principal distributions, if any, to the Fund.  The
    Fund seeks to maximize current income and to maintain liquidity and a
    stable net asset value by investing in short term U.S. Treasury
    Obligations which have effective maturities of one year or less.  For more
    complete information concerning the Fund, including charges and expenses,
    the Certificateholder should fill out and mail the card attached to the
    inside back cover of this Prospectus.  The prospectus for the Fund will be
    sent to Certificateholders.  The Certificateholder should read the
    prospectus for the Fund carefully before deciding to participate.  The
    shares of the Fund are not rated by Standard & Poor's.   


                               TRUST ADMINISTRATION

    Portfolio Supervision

              Each Trust is a unit investment trust and is not an actively
    managed fund.  Traditional methods of investment management for a managed
    fund typically involve frequent changes in a portfolio of securities on
    the basis of economic, financial and market analyses.  The portfolios of
    the Trusts, however, will not be actively managed and therefore the
    adverse financial condition of an issuer will not require the sale of its
    Securities from the Portfolios.   However, the Sponsors may direct the
    disposition of Securities upon default in payment of amounts due on any of
    the Securities, institution of certain legal proceedings, default in
    payment of amounts due on other securities of the same issuer or
    guarantor, or decline in price or the occurrence of other market or credit
    factors that in the opinion of the Sponsors would make the retention of
    these Securities detrimental to the interest of the Certificateholders. 
    If a default in the payment of amounts due on any Security occurs and if
    the Sponsors fail to give instructions to sell or hold that Security, the
    Indenture provides that the Trustee, within 30 days of that failure by the
    Sponsors, shall sell the Security.

              The Sponsors are required to instruct the Trustee to reject any
    offer made by an issuer of any of the Securities to issue new Securities
    in exchange or substitution for any Securities pursuant to a refunding or
    refinancing plan, except that the Sponsors may instruct the Trustee to
    accept or reject any offer or to take any other action with respect
    thereto as the Sponsors may deem proper if (a) the issuer is in default
    with respect to these Securities or (b) in the written opinion of the
    Sponsors the issuer will probably default with respect to these Securities
    in the reasonably foreseeable future.  Any Securities so received in
    exchange or substitution will be held by the Trustee subject to the terms
    and conditions of the Indenture to the same extent as Securities
    originally deposited thereunder.  Within five days after the deposit of
    Securities in exchange or substitution for underlying Securities, the
    Trustee is required to give notice thereof to each Certificateholder,
    identifying the Securities eliminated and the Securities substituted
    therefor.  Except as stated herein, the acquisition by the Trust of any
    securities other than the Securities initially deposited is prohibited.

    Trust Agreement, Amendment and Termination

              The Trust Agreement may be amended by the Trustee, the Sponsors
    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
    Certificateholders; provided that no such amendment or waiver shall reduce
    any Certificateholder's interest in a 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 in a Trust then outstanding, to increase the number of Units
    issuable or to permit the acquisition of any bonds in addition to or in
    substitution for those initially deposited in such Trust, except in
    accordance with the provisions of the Trust Agreement.  The Trustee shall
    promptly notify Certificateholders, in writing, of the substance of any
    such amendment.

              The Trust Agreement provides that the Trust shall terminate upon
    the maturity, redemption or other disposition, as the case may be, of the
    last of the Securities held in the Trust but in no event is it to continue
    beyond the end of the calendar year preceding the fiftieth anniversary of
    the execution of the Trust Agreement.  If the value of the Trust shall be
    less than the minimum amount set forth under "Summary of Essential
    Information" in Part A, the Trustee may, in its discretion, and shall when
    so directed by the Sponsors, terminate such Trust.  Each Trust may also be
    terminated at any time with the consent of the holders of Certificates
    representing 100% 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 Securities remaining in the terminated Trust, and,
    after paying all expenses and charges incurred by the Trust, distribute to
    each Certificateholder, upon surrender for calculation of his Certificate
    for Units, his pro rata share of the Interest and Principal Accounts.

    The Sponsors

              The Sponsors, Bear, Stearns & Co. Inc. and Gruntal & Co.,
    Incorporated, have entered into an Agreement Among Co-Sponsors pursuant to
    which both parties have agreed to act as Co-Sponsors for the Trust.  Bear,
    Stearns & Co. Inc., has been appointed by Gruntal & Co., Incorporated as
    agent for purposes of taking any action required or permitted to be taken
    by the Sponsors under the Trust Agreement.  If the Sponsors are unable to
    agree with respect to action to be taken jointly by them under the Trust
    Agreement and they cannot agree as to which Sponsor shall act as sole
    Sponsor, then Bear, Stearns & Co. Inc. shall act as sole Sponsor.  If one
    or the Sponsors fails to perform its duties under the Trust Agreement or
    becomes incapable of acting or becomes bankrupt or its affairs are taken
    over by public authorities, that Sponsor may be discharged under the Trust
    Agreement and a new Sponsor may be appointed or the remaining Sponsor may
    continue to act as Sponsor.

              The information included herein is only for the purpose of
    informing investors as to the financial responsibility of the Sponsors and
    their ability to carry out their contractual obligations.

              The Sponsors are joint and severally liable for the performance
    of their obligations arising from their 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 their
    own willful misfeasance, bad faith, gross negligence or reckless disregard
    of its obligations and duties.

              The Sponsors may resign at any time by delivering to the Trustee
    an instrument of resignation executed by the Sponsors.

              If at any time either of the Sponsors shall resign or 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) terminate the Trust Agreement and liquidate the Trust; or (c) continue
    to act as Trustee without terminating the Trust Agreement.  Any successor
    Sponsor appointed by the Trust shall be satisfactory to the Trustee and,
    at the time of appointment, shall have a net worth of at least $1,000,000.

    The Trustee

              The Trustee is United States Trust Company of New York, with its
    principal place of business at 770 Broadway, New York, New York 10003. 
    United States Trust Company of New York has, since its establishment in
    1853, engaged primarily in the management of trust and agency accounts for
    individuals and corporations.  The Trustee is a member of the New York
    Clearing House Association and is subject to supervision and examination
    by the Superintendent of Banks of the State of New York, the Federal
    Deposit Insurance Corporation and the Board of Governors of the Federal
    Reserve System.

              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, Securities or Certificates in accordance with
    the Trust Agreement, except in cases of its 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 Securities or the
    Trusts which it 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 Securities pursuant to the Trust
    Agreement.

              For further information relating to the responsibilities of the
    Trustee under the Trust Agreement, reference is made to the material set
    forth under "Rights of Certificateholders.

              The Trustee may resign by executing an instrument in writing and
    filing the same with the Sponsors, and mailing a copy of a notice of
    resignation to all Certificateholders.  In such an event, the Sponsors are
    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 Sponsors 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 Sponsors.  If upon resignation of the Trustee no
    successor has been appointed and has accepted the appointment within
    thirty days after notification, the retiring 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.

    also provides financial information services.  

              The Trustee, the Sponsors and the 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 Sponsors 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 Sponsors and
    Trustee, and the Sponsors and the Trustee are to use their 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 CHANGES

              At no cost to the Trust, the Sponsors have 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 and the Units under the Investment Company Act of 1940 and the
    Securities Act of 1933, the initial preparation and printing of the
    Certificates, the fees of the Evaluator during the initial public
    offering, legal expenses, advertising and selling expenses, expenses of
    the Trustee including, but not limited to, an amount equal to interest
    accrued on certain "when issued" securities since the date of settlement
    for the Units, initial fees and other out-of-pocket expenses.

              The Sponsors will not charge the Trust a fee for its services as
    such.  (See "Sponsors' and Underwriters' Profits.")

              The Sponsors will receive for portfolio supervisory services to
    the Trusts an Annual Fee in the amount set forth under "Summary of
    Essential Information" in Part A.  The Sponsors' fee may exceed the actual
    cost of providing portfolio supervisory services for the Trust, but at no
    time will the total amount received for portfolio supervisory services
    rendered to all series of the Mortgage Securities Trusts in any calendar
    year exceed the aggregate cost to the Sponsors of supplying such services
    in such year.  (See "Portfolio Supervision.")  Pursuant to the Agreement
    Among Co-Sponsors, Bear Stearns shall receive the entire Sponsors' fee set
    forth in the "Summary of Essential Information" in Part A.

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

              The Evaluator will receive, for each daily evaluation of the
    Securities in the Trust after the initial public offering is completed, a
    fee in the amount set forth under "Summary of Essential Information" in
    Part A.

              The Trustee's and Evaluator's fees applicable to the Trust are
    payable monthly as of the Record Date from the Interest Account of such
    Trust 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 and
    advances made in connection with its 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 it without gross negligence, bad faith
    or willful misconduct on its part, arising out of or in connection with
    its acceptance or administration of the Trust; indemnification of the
    Sponsors for any losses, liabilities and expenses incurred in acting as
    sponsors of the Trust without gross negligence, bad faith or willful
    misconduct on its part; and all taxes and other governmental charges
    imposed upon the Securities or any part of the Trust (no such taxes or
    charges are being levied, made or, to the knowledge of the Sponsors,
    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
    to which such expenses are charged.  In addition, the Trustee is empowered
    to sell Securities in order to make funds available to pay all expenses.

              The accounts of the Trusts shall be audited not less than
    annually by independent public accountants selected by the Sponsors.  The
    expenses of the audit shall be an expense of the Trust.  So long as the
    Sponsors maintain a secondary market, the Sponsors will bear any audit
    expense which exceeds $.50 per 1,000 Units.  Certificateholders covered by
    the audit during the year may receive a copy of the audited financials
    upon request.

                      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 and Exchange Commission)
    (the "Exchange Trusts") at a reduced sales charge as set forth below. 
    Under the Exchange Privilege, the Sponsors' repurchase price 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 (or for units of Equity Securities Trust, based on the
    market value of the underlying Securities in the Equity Trust portfolio)
    during the initial public offering period of the Exchange Trust; 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 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 certificateholders who wish to exercise the Exchange
    Privilege within the first five months of their purchase of Units of a
    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 certificateholders who wish to exercise the
    Exchange Privilege within the first five months of their purchase of Units
    of a 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 certificateholder 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 Sponsors 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 Sponsors have indicated
         their intention to maintain a market in the Units of all Trusts
         sponsored by it, the Sponsors are 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 Certificate-
         holder'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 Sponsors' 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 Sponsors reserve the right to suspend, modify or
         terminate the Exchange Privilege.  The Sponsors will provide
         certificateholders 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 Sponsors
         will continue to maintain a secondary market in the units of all
         Exchange Trusts that could be acquired by the affected
         certificateholders.  Certificateholders 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 Sponsors 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 five 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 units 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 Sponsors (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 Equity Securities
    Trust, based on the market value of the underlying securities in the
    Equity Trust portfolio) during its initial public 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 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 certificateholders 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 certificateholders 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 certificateholder 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 Sponsors' 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.  Units of the Equity
         Securities Trust may only be acquired in blocks of 100 Units.

              3.   The Sponsors reserve 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 Sponsors also reserve the right to raise the sales
         charge based on actual increases in the Sponsors' 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 of 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 Sponsors 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 that a unit owner has five units of a Redemption Trust
    which he has held for more than five 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 for 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 for the
    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 New York taxes, except for
    that portion of the income which is 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.  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.  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.
       
    Tax Consequences of the Exchange Privilege
    and the Conversion Offer                  
        
              A surrender of units pursuant to the Exchange Privilege or the
    Conversion Offer will constitute a "taxable event" to the
    Certificateholder under the Internal Revenue Code.  The Certificateholder
    will realize a tax gain or loss that will be of a long- or short-term
    capital or ordinary income nature depending on the length of time the
    units have been held and other factors.  (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.  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.

    Rating of Units

              Standard & Poor's has rated the Units of the Trust AAA.  This is
    the highest rating assigned by Standard & Poor's (see Description of
    Standard & Poor's Ratings).  Standard & Poor's has been compensated by the
    Sponsors for its service in rating the Units.

                              DESCRIPTION OF RATINGS*


    Standard & Poor's Corporation

              A Standard & Poor's rating on the units of an investment trust
    (hereinafter referred to collectively as "units" and "trust") is a current
    assessment of creditworthiness with respect to the investments held by
    such trust.  This assessment takes into consideration the financial
    capacity of the issuers and of any guarantors, issuers, lessees, or
    mortgagors with respect to such investments.  The assessment, however,
    does not take into account the extent to which trust expenses or portfolio
    asset sales for less than the Trust's purchase price will reduce payment
    to the unit holder of the interest and principal required to be paid on
    the portfolio assets.  In addition, the rating is not a recommendation to
    purchase, sell or hold units, inasmuch as the rating does not comment as
    to market price of the units or suitability for a particular investor.


    *    As described by the rating companies themselves.

              Trusts rated AAA are composed exclusively of assets that,
    together with their credit support are rated AAA by Standard & Poor's. 
    Standard & Poor's defines its AAA rating for such assets as the highest
    rating assigned by Standard & Poor's to a debt obligation.  Capacity to
    pay interest and repay principal is extremely strong.

 Re:  Mortgage Securities Trust, CMO Series 1 (SEC Reg. #33-36316)

 Dear Mr. DeMarco:

      It is our understanding that you have filed with the Securities and
 Exchange Commission a fourth Post Effective Amendment on the above
 captioned fund, SEC file number 33-36316.

      Because the portfolio is composed solely of Federal National Mortgage
 Association (FNMA) guaranteed REMIC Pass-Through Certificates fully
 guaranteed as to principal and interest by FNMA and/or the Federal Home
 Loan Mortgage Corporation (FHLMC) guaranteed Multiclass Mortgage
 Participation Certificates fully as to principal and interest by FHLMC, we
 reaffirm the assignment of an "AAA" rating to the units of the trust.

      You have permission to use the name of Standard & Poor's Ratings
 Group and the above-assigned rating in connection with your dissemination
 of information relating to these units, provided that it is understood
 that the rating is not a "market" rating nor a recommendation to buy,
 hold, or sell the units of the trust.  Further, it should be understood
 the rating does not take into account the extent to which fund expenses or
 portfolio asset sales for less than the fund's purchase price will reduce
 payment to the unit holders of the interest and principal required to be
 paid on the portfolio assets.  S&P reserves the right to advise its own
 clients, subscribers, and the public of the rating.  S&P relies on the
 sponsor and its counsel, accountants, and other experts for the accuracy
 and completeness of the information submitted in connection with the
 rating.  S&P does not independently verify the truth or accuracy of any
 such information.

      This letter evidences our consent to the use of the name of Standard
 & Poor's Ratings Group in connection with the rating assigned to the units
 in the post-effective amendment referred to above.  However, this letter
 should not be construed as a consent by us, within the meaning of Section
 7 of the Securities Act of 1933, to the use of the name of Standard &
 Poor's Ratings Group in connection with the ratings assigned to the
 securities contained in the trust.  You are hereby authorized to file a
 copy of this letter with the Securities and Exchange Commission.

      Please be certain to send us three copies of your final prospectus as
 soon as it becomes available.  Should we not receive them within a
 reasonable time after the closing or should they not conform to the
 representations made to us, we reserve the right to withdraw the rating.

      We are pleased to have had the opportunity to be of service to you. 
 Our bill will be sent to you within one month.  If we can be of further
 help, please do not hesitate to call upon us.

        				Sincerely,



        				Richard P. Larkin
