                                    "Underlying Issuer") and payments of principal and
                                    interest made by the Underlying Issuer on the Bonds
                                    as discussed in more detail under "The Trust
                                    Certificates--General" herein.

OFFERED SECURITIES...............   The Trust will issue the Trust Certificates (the

                                    right to receive from the Trust:

                                    -     periodic payments of interest on the principal
                                          amount of your Trust Certificates accruing
                                          from March 25, 1999 at a rate of 7 5/8% per

                                          principal amount of your Trust Certificates is

                                    -     the pro rata share for your Trust Certificates
                                          of a single payment of principal of

REDEMPTION OF THE
     TRUST CERTIFICATES..........   The Underlying Issuer has the right, at its option, to
                                    redeem the Bonds at any time, in whole or in part
                                    from time to time, at an amount equal to the
                                    principal amount of the par value of Bonds to be
                                    redeemed, plus a Redemption Premium (as
                                    described below), if any.

                                    If the Underlying Issuer exercises its right to redeem
                                    the Bonds in whole or in part, the Trust will redeem
                                    your Trust Certificates, pro rata, for an amount at
                                    least equal to their principal amount. The amount, if
                                    any, by which the redemption price paid on the
                                    Bonds exceeds their principal amount is called
                                    "Redemption Premium." If the Underlying Issuer
                                    pays a Redemption Premium on the Bonds, you will
                                    receive the pro rata amount of such Redemption
                                    Premium corresponding to the principal amount of
                                    your Trust Certificates. See "Trust
                                    Certificates--Redemption of Trust Certificates"
                                    herein.

                                    The Underlying Issuer, however, is not required to
                                    redeem the Bonds.  Therefore, there can be no
                                    assurance that the Trust will repurchase your Trust
                                    Certificates prior to the Stated Maturity Date.
                                    Should the Trust redeem your Trust Certificates
                                    prior to the Stated Maturity Date, the Trustee will
                                    notify you by mail at least 15 days before such
                                    redemption date.

BONDS............................   J. C. Penney Company, Inc. 7 5/8% Debentures due

                                    name of Cede & Co., as the nominee of The
                                    Depository Trust Company ("DTC"). You will not
                                    receive a definitive certificate representing your
                                    interest, except in limited circumstances described in
                                    the accompanying Prospectus when Trust
                                    Certificates in fully registered, certificated form are
                                    issued. See "Certain Information Regarding the
                                    Certificates--Definitive Certificates" in the
                                    accompanying Prospectus.

TAX CONSIDERATIONS...............   Sidley & Austin, counsel to the Depositor, is of the
                                    opinion that under existing law (1) the Trust will be
                                    a grantor trust and not a partnership or an
                                    association taxable as a corporation; and (2) your
                                    Trust Certificates will represent beneficial interests
                                    in the Bonds. See "Certain Federal Income Tax
                                    Considerations" herein and in the accompanying
                                    Prospectus for additional information concerning the
                                    application of federal income tax laws.

ERISA CONSIDERATIONS.............   An "employee benefit plan" subject to the Employee
                                    Retirement Income Security Act of 1974, as
                                    amended ("ERISA"), or a "plan" subject to Section
                                    4975 of the Internal Revenue Code of 1986
                                    ("Code"), contemplating the purchase of Trust
                                    Certificates should consult with its counsel before
                                    making such a purchase.  The fiduciary of such an
                                    employee benefit plan or plan and such legal
                                    advisors should consider whether the Trust
                                    Certificates will satisfy all of the requirements of the
                                    "Publicly-Offered Securities Exception" described
                                    herein or the possible application of other
                                    "prohibited transaction exemptions" described
                                    herein.  See "Certain ERISA Considerations" herein
                                    and in the accompanying Prospectus.

LISTING..........................   The Trust Certificates have been approved for
                                    listing, subject to official notice of issuance, on the
                                    New York Stock Exchange.  Trading of the Trust
                                    Certificates on the New York Stock Exchange is
                                    expected to commence within a 30-day period after
                                    the initial delivery thereof.  See "Underwriting."

RATINGS..........................   It is a condition to issuance that the Trust
                                    Certificates be rated investment grade by each of
                                    Moody's Investors Service, Inc. ("Moody's") and
                                    Standard & Poor's Ratings Group ("S&P").  In
                                    January 1999, Moody's placed the ratings of the
                                    Underlying Issuer under review for possible
                                    downgrade, and S&P placed such ratings on
                                    CreditWatch with negative implications.  Thus, it is
                                    possible that the Bonds may be downgraded from
                                    their current ratings of "A2" by Moody's and "A" by
                                    S&P.  See "Risk Factors" herein.

                                  RISK FACTORS


      You should consider the following factors in deciding whether to purchase
the Trust Certificates:


            1. NO DETAILED INFORMATION ABOUT BONDS OR UNDERLYING ISSUER. This
      Prospectus Supplement does not provide you with detailed information with
      respect to the Bonds or the Underlying Issuer, any risk factors relating
      thereto, or any legal, financial or other rights or obligations arising
      under or related to the Bonds. See "Available Information Regarding The
      Corporate Obligors" in the accompanying Prospectus and "Appendix
      A--Description of Bonds--Available Information" herein.

            2. UNDERLYING ISSUER IS THE ONLY PAYMENT SOURCE. The payments made
      by the Underlying Issuer on the Bonds are the only source of payment on
      your Trust Certificates. The Underlying Issuer is subject to laws
      permitting bankruptcy, moratorium, reorganization or other actions; should
      the Underlying Issuer experience financial difficulties, this could result
      in delays in payment, partial payment or non-payment of your Trust
      Certificates. See "The Trust Certificates--Default on Bonds" herein.

            3. RISK OF DOWNGRADE. In January 1999, Moody's placed the ratings of
      the Underlying Issuer under review for possible downgrade, and S&P placed
      such ratings on CreditWatch with negative implications. Thus, it is
      possible that the Bonds may be downgraded from their current ratings of
      "A2" by Moody's and "A" by S&P. Any such downward revision may have an
      adverse effect on the market prices of the Trust Certificates.


                             THE TRUST CERTIFICATES


GENERAL


      The Trust Certificates (the "Trust Certificates") relate to $52,650,000
aggregate principal amount (of $500,000,000 aggregate principal amount issued in
February 1997) of 7 5/8% Debentures due 2097 (the "Bonds") of J. C. Penney
Company, Inc. (the "Underlying Issuer"). The Bonds provide for semiannual
interest payments ("Interest Payments") due on March 1 and September 1 of each
year (each, an "Interest Payment Date") and for a single payment of principal of
$52,650,000 (the "Principal Payment") payable on March 1, 2097 (the "Stated
Maturity Date") or upon earlier redemption.

      The Trust Certificates are issued in a single class with a principal
amount of $52,650,000. Each Trust Certificate evidences the right to receive
periodic interest payments on its principal amount accruing from March 25, 1999,
at a rate of 7 5/8% per annum on each September 1 and


                                       S-8
<PAGE>   9
March 1, commencing September 1, 1999, until the principal amount of such Trust
Certificate is paid on the Stated Maturity Date, or upon the earlier redemption
of such Trust Certificate. Interest shall be computed on the basis of a 360-day
year consisting of twelve 30-day months. The Trust Certificates evidence
ownership in the aggregate of all of the Interest Payments, and of the Principal
Payment, due on the Bonds. In addition, the Trust Certificates are entitled to
the Redemption Premium, if any, payable by the Underlying Issuer upon a
redemption of the Bonds by the Underlying Issuer. See "--Redemption of Trust
Certificates" herein.

      The Bonds were transferred to the Trust exclusive of the right to receive
interest on the Bonds accrued from March 1, 1999 until, but excluding, March 25,
1999 (the "Retained Amount"). Therefore, the interest payment that purchasers of
Trust Certificates (each, a "Certificateholder") are scheduled to receive on the
interest payment date on September 1, 1999 will not include the Retained Amount
and the Retained Amount will be distributed to the Depositor or its designee.

      The scheduled interest and principal payments on the Trust Certificates
are payable solely from payments of principal and interest on the Bonds made by
the Underlying Issuer. If payments are not made on the Bonds, the
Certificateholders will not be paid and will suffer losses. You should avail
yourself of the same information concerning the Underlying Issuer as you would
if you were purchasing the Bonds. See "Available Information Regarding The
Corporate Obligors" in the Prospectus and "Appendix A--Description of
Bonds--Available Information" herein. Information with respect to the Underlying
Issuer is also available at the Underlying Issuer's corporate website
(http://www.jcpenneyinc.com/investor.htm).

      Pursuant to the Trust Agreement, the Bonds underlying the Trust
Certificates will be held by the Trustee for the benefit of the
Certificateholders as book-entry credits to an account of the Trustee at DTC.
The Underlying Issuer is not a party to the Trust Agreement. Each
Certificateholder, by its acceptance of a Trust Certificate, agrees to be bound
by the terms and conditions of the Trust Agreement. Copies of the Trust
Agreement are available upon written request from PaineWebber at 1285 Avenue of
the Americas, New York, New York 10019.

      The Trust Certificates will be delivered in registered form. Each Trust
Certificate will have a principal amount of $25. The Trust Certificates are
being offered initially in book entry form only through DTC, and purchasers will
not receive physical certificates representing their ownership of Trust
Certificates.

      The Trust Certificates offered hereby are different from, and not
exchangeable for, any other series of Trust Certificates or any other receipt or
certificate evidencing ownership of future interest or principal payments due on
Underlying Issuer obligations, and are subject to the terms and conditions of
the Trust Agreement.

      Neither the Trustee nor the Depositor will be responsible for the payments
due on the Trust Certificates, except that the Trustee will be required to apply
all payments received in respect of the Bonds, exclusive of the Retained Amount,
to the Trust Certificates to which they relate without making any deduction,
other than any applicable tax or other governmental charge.


                                       S-9
<PAGE>   10
REDEMPTION OF TRUST CERTIFICATES

      The Bonds as originally issued are redeemable at any time, in whole or in
part from time to time, on not less than 30 nor more than 60 days' notice, at
the option of the Underlying Issuer. In addition, upon the occurrence of certain
adverse tax events, the Underlying Issuer will have the right (i) to shorten the
maturity of the Bonds to the extent required to cure the adverse consequences of
such tax event, or (ii) under certain circumstances, within 90 days of the
occurrence of such an event, to redeem the Bonds in whole (but not in part), on
not less than 30 nor more than 60 days' notice. The redemption price for the
Bonds will be equal to the par value of the Bonds to be redeemed plus accrued
interest on the principal amount being redeemed, plus a Redemption Premium, if
any.

      The holder of a Trust Certificate which is redeemed will receive a payment
equal to its pro rata share of the greater of (i) the par value of the Bonds to
be redeemed and (ii) the sum of the present value of the remaining scheduled
payments thereon discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at a certain
benchmark interest rate plus 20 basis points (or, in the case of a redemption in
connection with the occurrence of an adverse tax event, 40 basis points),
together in either case with accrued interest on the principal amount being
redeemed to the date of redemption. The amount, if any, by which the amount
described in (ii) above exceeds the amount described in (i) is referred to
herein as "Redemption Premium."

      On or after the redemption date, interest will cease to accrue on the
Trust Certificates or on any portion thereof called for redemption.

      Subject to receipt by the Trustee of actual notice of such redemption from
the Underlying Issuer, the principal amount of Trust Certificates corresponding
to the principal amount of Bonds to be redeemed will be called for redemption.
Notice of such call shall be given by the Trustee to the registered
Certificateholders not less than 15 days prior to the redemption date by mail to
each registered Certificateholder at such registered Certificateholder's last
address on the register maintained by the Trustee; provided, however, that the
Trustee shall not be required to give any notice of redemption prior to the
third business day after the date it receives notice of such redemption.

DEFAULT ON BONDS

      If the Underlying Issuer defaults on the payment of interest or principal
of any Bond, the Trustee shall promptly give notice to DTC or, for any Trust
Certificates which are not then held by DTC or any other depository, directly to
the registered holders thereof. Such notice shall set forth (a) the identity of
the issue of Bonds, (b) the date and nature of such default, (c) the principal
amount of the interest or principal in default, (d) the Trust Certificates
affected by the default, and (e) any other information which the Trustee may
deem appropriate.

      In the event of a payment default on the Bonds the Trustee is required to
proceed against the Underlying Issuer on behalf of the Certificateholders to
enforce the Bonds or otherwise to protect the interests of the
Certificateholders, subject to the receipt of indemnity in form and


                                      S-10
<PAGE>   11
substance satisfactory to the Trustee; provided, that holders of Trust
Certificates representing a majority of the voting rights on the Trust
Certificates will be entitled to direct the Trustee in any such proceeding,
subject to the Trustee's receipt of satisfactory indemnity.

      In the event that the Trustee receives money or other property in respect
of the Bonds (other than a scheduled Interest Payment on or with respect to an
Interest Payment Date) as a result of a payment default on the Bonds, or actual
notice that such moneys or other property will be received, the Trustee will
promptly give notice as provided in the Trust Agreement to DTC, or for any Trust
Certificates which are not then held by DTC or any other depository, directly to
the registered holders of the Trust Certificates then outstanding and unpaid.
Such notice will state that, not later than 30 days after the receipt of such
moneys or other property, the Trustee will allocate and distribute such moneys
or other property to the holders of Trust Certificates then outstanding and
unpaid, pro rata by principal amount. Property other than cash will be
liquidated by the Trustee, and the proceeds thereof distributed in cash, only to
the extent necessary to avoid distribution of fractional securities to
Certificateholders. Any such amounts received by the Trustee in excess of
principal and accrued unpaid interest on the Trust Certificates will be
distributed to the Depositor. In-kind distribution of Bonds to
Certificateholders will be deemed to reduce the principal amount of Trust
Certificates on a dollar for dollar basis. No amounts will be distributed to the
Depositor in respect of the Bonds unless and until principal and accrued
interest on the Trust Certificates has been paid (or reduced by distributions in
kind) in full.

      Interest and principal payments on the Bonds are payable solely by the
Underlying Issuer. The Underlying Issuer is subject to laws permitting
bankruptcy, liquidation, moratorium, reorganization or other actions which, in
the event of financial difficulties of the Underlying Issuer, could result in
delays in payment, partial payment or non-payment of the Trust Certificates
relating to a Bond.

DTC BOOK ENTRY ONLY SYSTEM

      The Depositor will deliver Trust Certificates to investors in book-entry
form only through the facilities of DTC (the "DTC Book Entry Only System"),
against payment in same day funds. Delivery will be made to investors at the
offices of the Underwriter or to an office (specified by the investor) of an
entity that is a Participant or Indirect Participant (as defined in the
Prospectus). See "Certain Information Regarding the Certificates--Book-Entry
Registration" in the Prospectus.


                       THE TRUSTEE AND THE TRUST AGREEMENT

      The following summary as well as other pertinent information included
elsewhere in this Prospectus Supplement and the Prospectus describes the
material terms generally applicable to the Trust Certificates, but does not
purport to be complete and is expressly made subject to the actual provisions of
the documents. For details of all terms and conditions, reference is made to the
Trust Agreement, a copy of which is available for inspection at the offices of
the Trustee or, during the offering period, at the offices of the Depositor.


                                      S-11
<PAGE>   12
      Pursuant to the Trust Agreement, the Bonds underlying the Trust
Certificates will be held for the Certificateholders by United States Trust
Company of New York (the "Trustee") initially as book-entry credits to an
account of the Trustee at DTC. The Trustee will establish a separate trust
account for the Bonds relating to Trust Certificates offered hereby. It is the
intent of the Depositor that all of the Bonds will be held by the Trustee by
book-entry credit to its account at DTC. If, for any reason, the Bonds may no
longer be held by book-entry credit at DTC, the Bonds will thereafter be held by
the Trustee in a separate trust account.

      Prior to a payment default by the Underlying Issuer, the only
responsibility of the Trustee with respect to payments on Trust Certificates
will be to apply all payments received in respect of the Bonds to the registered
Certificateholders without making any deductions other than for any taxes and
governmental charges. After a payment default by the Underlying Issuer, the
Trustee is required to proceed against the Underlying Issuer on behalf of the
Certificateholders to enforce the Bonds or otherwise to protect the interests of
the Certificateholders, subject to the receipt of indemnity in form and
substance satisfactory to the Trustee. See "The Trust Certificates--Default on
Bonds" herein.

      Trust accounts established for Trust Certificates will be accounts
identified and held separate and apart from the general assets of the Trustee
and will not contain any property of the Trustee in its individual capacity.
Pursuant to the Trust Agreement, the Trustee has agreed that it does not have
the authority to assign, transfer, encumber, pledge, sell, set-off or otherwise
dispose of any of the Bonds or any interests therein except as provided
thereunder or as required by law.

      The Trust Agreement provides that the Trustee shall keep at its designated
office in New York, New York a register (the "Certificate Register") in which,
subject to such reasonable regulations as it may prescribe, the Trustee shall
provide for the registration of, and for the registration of transfers or
exchanges of, Trust Certificates. Notwithstanding the foregoing, under the DTC
Book Entry Only System, transfers and exchange of Trust Certificates will be
accomplished as described under "Certain Information Regarding the Certificates"
in the Prospectus. Under the DTC Book Entry Only System, DTC will be the sole
registered holder of the Trust Certificates.

      The voting rights on the Trust Certificates will be apportioned among the
Certificateholders pro rata by principal amount. The Trust Agreement provides
that, in the event of any action requiring a vote of the registered holders of
any Bonds, the Trustee (as the owner of record of the Bonds), upon receipt of
the Bond proxy, will notify DTC (in its capacity as the owner of record of the
Trust Certificates) of such action. Pursuant to currently existing procedures,
it is expected that DTC, in turn, will notify its Participants (including the
Depositor) who, in turn, will notify the Certificateholders of such event. The
Certificateholders will give their proxies to their Participants. The
Participants will give such proxies to DTC, and DTC will give such proxies to
the Trustee. Thereafter, the Trustee will vote solely in accordance with such
proxies and will apportion its voting power on the basis of the votes cast by
the Certificateholders. In the event that the Trust Certificates have been
removed from the DTC Book Entry Only System and are held as physical
certificates, the Trustee, upon receipt of the


                                      S-12
<PAGE>   13
Bond proxy, will notify the registered Certificateholders directly of such
action and shall vote in the same manner as noted above. In casting any votes on
the Bonds in connection with the foregoing, the Trustee will be required to cast
its vote on the Bonds in proportion to the voting rights on the Trust
Certificates held by Certificateholders so directing it, notwithstanding that
such Certificateholders may give contrary instructions. In no event shall the
Depositor be allowed or entitled (other than in its capacity as a safekeeper for
a Certificateholder) to vote, directly or indirectly through the Trustee, any
Trust Certificates or the Bonds.

      The Trustee shall at no time vote for or consent to any action (i) to the
extent that such vote or consent could reasonably be expected to alter the
status of the Trust as a grantor trust for federal income tax purposes, (ii)
prior to the filing of a bankruptcy petition by or against the Underlying
Issuer, or the commencement of any other similar proceeding, if such action
would alter the timing or amount of any payment on the Bonds or (iii) prior to
the filing of a bankruptcy petition by or against the Underlying Issuer, or the
commencement of any other similar proceeding, if such action would result in the
exchange or substitution of any of the outstanding Bonds pursuant to a plan for
the refunding or refinancing of such Bonds.

      The Trustee will maintain a fidelity bond in reasonable form and amount to
protect against loss resulting from the dishonest or fraudulent action by its
employees in connection with the Trustee's obligations under the Trust
Agreement.

      The Trust Agreement provides that neither the Trustee nor the Depositor
shall be subject to any liabilities to Certificateholders other than by reason
of willful misconduct, bad faith or negligence in the performance of duties set
forth in the Trust Agreement and that neither of them shall be liable to such
Certificateholders if any law, government regulation or other circumstance
prevents or delays the performance of duties set forth in the Trust Agreement.

      DTC will not be deemed an agent of the Trustee. The Trustee may own and
deal in bonds of the same issue and maturity as the Bonds and in Trust
Certificates.

      The Trustee and the Depositor may amend the Trust Agreement, provided that
no amendment may be made which defers or alters the maturity of a Trust
Certificate or which in any manner adversely affects the rights of a
Certificateholder to the payment of interest, principal or premium, if any,
evidenced thereby or otherwise materially prejudices any substantial existing
right of such a Certificateholder.

      The Trustee may at any time resign as Trustee by written notice to the
Depositor, such resignation to take effect upon the appointment of a successor
Trustee, subject to the terms and conditions of the Trust Agreement.

      The Depositor may at any time remove the Trustee as Trustee under the
Trust Agreement by written notice of its election to do so, delivered to the
Trustee, and such removal shall take effect upon the appointment of a successor
Trustee and its acceptance of such appointment, subject to the terms and
conditions of the Trust Agreement.

      In the event that the Trustee becomes incapable of acting, is adjudged to
be bankrupt or insolvent, or a receiver of the Trustee or of its property is
appointed, or any public officer takes


                                      S-13
<PAGE>   14
charge or control of the Trustee or of its property or affairs for the purpose
of rehabilitation, conservation or liquidation, then the Trustee may be removed
by court action instituted by any Certificateholder who has been a
Certificateholder for six months or by Certificateholders of 10% of the
principal amount of Trust Certificates outstanding at such time.


                                  UNDERWRITING


      Subject to the terms and conditions set forth in the Underwriting
Agreement (the "Underwriting Agreement") between the Underwriters named below
(the "Underwriters") and the Trust, the Trust will sell the Trust Certificates
to the Underwriters, and each of the Underwriters has agreed to purchase from
the Trust the respective number of Trust Certificates set forth opposite its
name. In the Underwriting Agreement, the Underwriters have agreed, subject to
the terms and conditions set forth therein, to purchase all of the Trust
Certificates if any Trust Certificates are purchased.

      The Trust has been advised by the Underwriters that they propose initially
to offer the Trust Certificates to the public at the public offering price set
forth on the cover page of this Prospectus Supplement, and to certain dealers at
such price less a concession not in excess of $.50 per Trust Certificate. The
Underwriters may allow and such dealers may reallow a concession not in excess
of $.25. After the initial public offering, the public offering price and the
concessions may be changed.

      The Trust Certificates are a new issue of securities with no established
trading market. The Trust Certificates have been approved for listing, subject
to official notice of issuance, on the New York Stock Exchange. Trading of the
Trust Certificates on the New York Stock Exchange is expected to commence within
a 30-day period after the initial delivery thereof. In order to meet one of the
requirements for listing the Trust Certificates on the New York Stock Exchange,
the Underwriters have undertaken to sell the Trust Certificates to a minimum of
400 beneficial owners. The Underwriters have told the Depositor that they
presently intend to make a market in the Trust Certificates prior to
commencement of trading on the New York Stock Exchange, as permitted by
applicable laws and regulations. The Underwriters are not obligated, however, to
make a market in the Trust Certificates. Any market making by the Underwriters
may be discontinued at any time at the sole discretion of the Underwriters. No
assurance can be given as to whether a trading market for the Trust Certificates
will develop or as to the liquidity of any trading market.

      Until the distribution of the Trust Certificates is completed, rules of
the Commission may limit the ability of the Underwriters to bid for and purchase
the Trust Certificates. As an exception to these rules, the Underwriters are
permitted to engage in certain transactions that stabilize the price of the
Trust Certificates. Possible transactions consist of bids or purchases for the
purpose of pegging, fixing or maintaining the price of the Trust Certificates.

      If the Underwriters create a short position in the Trust Certificates in
connection with this offering, that is, if they sell a greater aggregate
principal amount of Trust Certificates than is set forth on the cover page of
this Prospectus Supplement, the Underwriters may reduce that short position by
purchasing Trust Certificates in the open market. The Underwriters may also
impose a penalty bid on certain selling group members. This means that if an
Underwriter purchases Trust Certificates in the open market to reduce its short
position or to stabilize the price of the Trust Certificates, it may reclaim the
amount of the selling concession from the selling group members who sold those
Trust Certificates as part of the offering.

      In general, purchases of a security for the purposes of stabilization or
to reduce a short position could cause the price of the security to be higher
than it might be in the absence of such purchases. The imposition of a penalty
bid might also have an effect on the price of a Trust Certificate to the extent
that it were to discourage resales of the Trust Certificates.

      Neither the Depositor nor the Underwriters make any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above might have on the price of the Trust Certificates. In addition,
neither the Depositor nor the Underwriters make any representation that the
Underwriters will engage in such transactions. Such transactions, once
commenced, may be discontinued without notice.

      The Depositor has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended
(the "Securities Act"), or to contribute to payments that the Underwriters may
be required to make in respect thereof.

      The entire net proceeds received by the Trust from the sale of the Trust
Certificates will be used to acquire the Bonds from the Depositor, which will
use such proceeds to acquire the Bonds from PaineWebber Incorporated
("PaineWebber"). Thus, neither the Trust nor the Depositor is expected to
receive any net cash proceeds from the sale of the Trust Certificates.


                                  LEGAL MATTERS

      Certain legal matters relating to the offering and sale of the Trust
Certificates and certain federal income tax aspects thereof will be passed upon
by Sidley & Austin, New York, New York.


                                     RATINGS

      It is a condition to issuance of the Trust Certificates that each of
Moody's and S&P shall have assigned an investment grade rating to the Trust
Certificates. The rating given to the Trust Certificates will be based primarily
upon the credit rating of the related Bonds and the legal


                                      S-15
<PAGE>   16
structure of the transaction, including the limitation that payments in respect
of the Trust Certificates are subject to receipt by the Trustee of payments on
the Bonds.

      There is no assurance that any rating will remain in effect for any given
period of time or that it will not be revised downward or withdrawn entirely by
the rating agency, if in the judgment of the rating agency, circumstances so
warrant. Securities ratings address the likelihood that the purchasers of Trust
Certificates will receive all payments required under the Trust Agreement. In
January 1999, Moody's placed the ratings of the Underlying Issuer under review
for possible downgrade, and S&P placed such ratings on CreditWatch with negative
implications. Thus, it is possible that the Bonds may be downgraded from their
current ratings of "A2" by Moody's and "A" by S&P. Any such downward revision or
withdrawal of such rating may have an adverse effect on the market prices of the
Trust Certificates.

      A security rating is not a recommendation to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning
entity. The Depositor has not requested a rating of the Trust Certificates from
any rating agency other than Moody's and S&P. However, there can be no assurance
as to whether any other rating agency will rate the Trust Certificates, or if
one does, what rating would be assigned by such rating agency.


                    CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

      In the opinion of Sidley & Austin, for federal income tax purposes, (1)
the Trust will be treated as a grantor trust under subpart E of Part I of
subchapter J of the Code and not as a partnership or an association taxable as a
corporation, and (2) the Trust Certificates will represent undivided beneficial
ownership interests in the interest and principal payments on the Bonds. The
Bonds will likely be treated as "stripped bonds." To the extent that the
allocable purchase price paid by a Certificateholder for its interest in the
Bonds exceeds the Certificateholder's interest in the Bonds' principal balance,
the Bonds will be acquired with amortizable bond premium. A Certificateholder
may elect to amortize such premium as an offset to interest income. See "Certain
Federal Income Tax Considerations--Taxation of Certificateholders--Stripped
Certificates" in the Prospectus.


                         CERTAIN ERISA CONSIDERATIONS

GENERAL

      As more fully described in the accompanying Prospectus, Section 406 of
ERISA and Section 4975 of the Code prohibit certain "employee benefit plans," as
defined in and subject to ERISA, and "plans," as defined in and subject to
Section 4975 of the Code (such employee benefit plans and plans referred to
herein as "Plans"), from engaging in certain transactions involving "plan
assets" with persons that are "parties in interests" under ERISA or
"disqualified persons" under the Code with respect to the Plan. A violation of
these "prohibited transaction" rules may generate excise tax and other
liabilities under ERISA and the Code for such persons. For example, a prohibited
transaction would arise, unless an exemption were applicable, if


                                      S-16
<PAGE>   17
PaineWebber were a party in interest or disqualified person with respect to a
Plan that acquired Trust Certificates from PaineWebber.

      Moreover, additional prohibited transactions could arise if the assets of
the Trust were deemed to constitute plan assets of any Plan that owned Trust
Certificates. The Department of Labor ("DOL") has issued a final regulation (the
"DOL Regulation") concerning the definition of what constitutes the "plan
assets" of a Plan. Under the DOL Regulation the assets and properties of certain
corporations, partnerships and certain other entities in which a Plan acquires
an "equity interest" could be deemed to be plan assets of each Plan unless one
of the exceptions under the DOL Regulation is applicable to the Trust.


AVAILABILITY OF PUBLICLY-OFFERED SECURITY EXCEPTION

      The DOL Regulation contains an exception (the "Publicly-Offered Securities
Exception") that provides generally that if a Plan acquires an equity interest
in another entity and that equity interest constitutes a "publicly-offered
security," then the assets of the entity are not deemed to be plan assets of
such Plan as a result of such acquisition. A publicly-offered security is a
security that is (i) freely transferable, (ii) part of a class of securities
that is owned by 100 or more investors independent of the issuer and of one
another and (iii) either is (A) part of a class of securities registered under
Section 12(b) or Section 12(g) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act") or (B) sold to the Plans as part of an offering of
securities to the public pursuant to an effective registration statement under
the Securities Act, and the class of securities of which such security is a part
is registered under the Exchange Act within 120 days (or such later time as may
be allowed by the Commission) after the end of the fiscal year of the issuer
during which the offering of such securities to the public occurred.

      It is anticipated that the Trust Certificates will meet the criteria of
the Publicly-Offered Securities Exception. First, the Trust Certificates are
being sold as part of a public offering pursuant to an effective registration
statement under the Securities Act, and will be timely registered under the
Exchange Act. Second, it appears that the Trust Certificates are freely
transferable because the minimum investment is not more than $25, and the Trust
Certificates generally may be transferred or exchanged upon payment of a service
charge of the Trustee and a sum sufficient for reimbursement of certain tax or
governmental charges and the making of certain representations and warranties.
As described in the accompanying Prospectus, the DOL Regulation provides that if
a security is part of an offering in which the minimum investment is $10,000 or
less, then a requirement that reasonable transfer or administrative fees be
paid, or that advance written notice (including representations as to compliance
with the requirements of the DOL Regulation or the entity's governing
instruments) be provided to the entity that issued the security, will not
prevent a finding that the security is freely transferable. Third, PaineWebber
expects (although no assurance can be given) that at the conclusion of the
offering, the Trust Certificates will be owned by at least 100 investors who are
independent of the Trust and each other. Therefore, it is anticipated that the
underlying assets of the Trust should not be deemed to constitute plan assets of
any Plan which purchases Trust Certificates.


                                      S-17
<PAGE>   18
      If the Trust Certificates fail to meet the criteria of the
Publicly-Offered Securities Exception so that the Trust's assets are deemed to
be plan assets of Plans that are owners of Trust Certificates, transactions
involving the Trust and parties in interest or disqualified persons with respect
to such Plans might be prohibited under Section 406 of ERISA and Section 4975 of
the Code unless a prohibited transaction exemption is applicable. There are five
class exemptions issued by the DOL that may apply in such event: DOL Prohibited
Transaction Exemption 84-14 (Class Exemption for Certain Transactions Determined
by a Qualified Professional Asset Manager), 90-1 (Class Exemptions for
Transactions Involving Insurance Company Pooled Separate Accounts), 91-38 (Class
Exemptions for Certain Transactions Involving Bank Collective Investment Funds),
95-60 (Class Exemption for Transactions Involving Insurance Company General
Accounts) and 96-23 (Class Exemption for Certain Transactions Determined by an
In-house Asset Manager). There is no assurance that these exemptions, even if
all of the conditions specified therein are satisfied, will apply to all
transactions involving the Trust's assets.


INELIGIBLE PURCHASERS

      Regardless of whether the Publicly-Offered Security Exception or the PTCEs
described above apply, Trust Certificates generally may not be purchased with
plan assets of a Plan if PaineWebber, the Depositor, the Underlying Issuer, the
Trustee or any of their respective affiliates either: (a) has investment
discretion with respect to the investment of such Plan's assets; (b) has
authority or responsibility to give or regularly gives investment advice with
respect to such Plan assets for a fee and pursuant to an agreement or
understanding that such advice will serve as a primary basis for investment
decisions with respect to such Plan assets and that such advice will be based on
the particular need of the Plan; or (c) is an employer maintaining or
contributing to such Plan.


REVIEW BY PLAN FIDUCIARIES

      Due to the complexity of these rules and the penalties imposed upon
persons involved in prohibited transactions, it is especially important that any
Plan fiduciary who proposes to cause a Plan to purchase Trust Certificates
should consult with its own counsel with respect to the potential consequences
under ERISA and the Code of the Plan's acquisition and ownership of Trust
Certificates. Assets of a Plan should not be invested in the Trust Certificates
unless it is clear that the assets of the Trust will not be plan assets of such
Plan or unless it is clear that a prohibited transaction class exemption will
apply and exempt all potential prohibited transactions.

      The Trust Certificates (the "Certificates") described herein may be sold
from time to time in one or more series, in amounts, at prices and on terms to
be determined at the time of sale and to be set forth in a supplement to this
Prospectus (each, a "Prospectus Supplement"). Each series of Certificates will
include one or more classes of Certificates.

      The Certificates of each series will be issued by a newly formed, limited
purpose trust to be formed with respect to such series (each, a "Trust").

                                                      (Continued on next page)

                                  ----------

      PROCEEDS OF THE ASSETS OF THE TRUST FOR ANY SERIES ARE THE SOLE SOURCE OF
PAYMENTS ON THE CERTIFICATES FOR SUCH SERIES. THE CERTIFICATES WILL NOT
REPRESENT AN INTEREST IN OR OBLIGATION OF, AND ARE NOT INSURED OR GUARANTEED BY,
THE DEPOSITOR OR PAINEWEBBER INCORPORATED, ANY OTHER TRUST OR ANY OF THEIR
RESPECTIVE AFFILIATES. THE CERTIFICATES ARE DIFFERENT FORM, AND SHOULD NOT BE
DEEMED TO BE A SUBSTITUTE FOR, DIRECT OWNERSHIP OF THE UNDERLYING ASSETS OF THE
TRUST.

                                   -----------

      THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.

      Certificates may be sold by the Depositor through agents designated from
time to time, through underwriting syndicates led by one or more managing
underwriters or through one or more underwriters acting alone, as more fully
described under "Plan of Distribution" and in the related Prospectus Supplement.
If underwriters or agents are involved in the offering of the Certificates of
any series offered hereby, the name of the managing underwriter or underwriters
or agents will be set forth in the related Prospectus Supplement.

      THIS PROSPECTUS MAY NOT BE USED TO CONSUMMATE SALES OF SECURITIES OFFERED
HEREBY UNLESS ACCOMPANIED BY A PROSPECTUS SUPPLEMENT.

                 The date of this Prospectus is March 18, 1999.
<PAGE>   23
(Continued from previous page)

      The property of each Trust will include securities (the "Bonds") that will
be identified in the related Prospectus Supplement and will be debt securities
issued by corporations that are subject to the information requirements of the
Securities Exchange Act of 1934 and in accordance therewith file reports and
other information with the Securities and Exchange Commission.

      Each Trust will be formed pursuant to a series trust deposit agreement
(the "Trust Agreement") to be entered into between Corporate Asset Backed
Corporation, as Depositor (the "Depositor"), and the Trustee specified in the
related Prospectus Supplement (the "Trustee").

      The Certificates of each class of any series will represent the right to
receive a specified amount or allocation of payments of principal and interest
on the related Bonds in the manner described herein and in the related
Prospectus Supplement. The Certificates will represent fractional undivided
interests in some or all of the interest and principal payments on the Bonds in
the related Trust.

      Each series of Certificates will represent the right to receive payments
or distributions in the amounts, at the rates, and on the dates set forth in the
related Prospectus Supplement. The rate of payment in respect of principal of
Certificates of any series will depend on the timing of payments on the related
Bonds.

      There will be no secondary market for the Certificates prior to the
offering thereof. While PaineWebber Incorporated intends to make a secondary
market in the Certificates, it is not obligated to do so. There can be no
assurance that a secondary market for the Certificates will develop or, if it
does develop, that it will continue. The Certificates may or may not be listed
on a securities exchange. If the Certificates are listed on a securities

                                          series initially issued in book-entry form will be
                                          able to receive Definitive Certificates only in the

                                          ("PaineWebber"), an affiliate of the Depositor,
                                          which acquired the Bonds in the secondary
                                          market.  The Trust, in turn, will acquire the
                                          Bonds from the Depositor.  The Bonds will be
                                          identified in the related Prospectus Supplement
                                          and will be debt securities issued by a

                                          registered on a registration statement on Form
                                          S-3 promulgated under the Securities Act of
                                          1933, as amended (the "Act"), which
                                          corporation will also be a reporting company
                                          under Section 12 or Section 15(d) of the
                                          Securities Exchange Act of 1934 at the time the
                                          Bonds are deposited in the Trust.  Each of the
                                          Bonds will have originally been issued in a
                                          transaction registered pursuant to the Act.
                                          PaineWebber will have previously purchased the
                                          Bonds in the secondary market.  PaineWebber
                                          will not have purchased the Bonds from the
                                          issuer thereof or any of its affiliates, and the
                                          Bonds will not have been purchased by
                                          PaineWebber as part of the initial distribution
                                          thereof.  After the date of issuance by each
                                          Trust of the related Certificates (the "Issuance
                                          Date"), such Trust will not purchase or
                                          otherwise acquire any additional securities and
                                          will not dispose of or create any lien on its
                                          assets, other than, upon termination of such
                                          Trust.

Payments ...............................  Subject to timely receipt of payments on the
                                          Bonds, payments in respect of the Certificates
                                          will be paid or distributed at such times and in
                                          such manner as described in the related
                                          Prospectus.

Certain Federal Income Tax
 Considerations.........................  Upon the issuance of each series of Certificates,
                                          Sidley & Austin, as counsel to the Depositor,
                                          will deliver an opinion to the effect that, for
                                          federal income tax purposes: (1) the Trust will
                                          be a grantor trust and not a partnership or an
                                          association taxable as a corporation; and (2) the
                                          Certificates will be interests in a grantor trust.
                                          See "Certain Federal Income Tax
                                          Considerations."

ERISA Considerations....................  As more fully described under "Certain ERISA
                                          Considerations," a particular Certificate may or
                                          may not be eligible for purchase by an
                                          "employee benefit plan" as described in and

                                          subject to the Employee Retirement Income
                                          Security Act of 1974, as amended ("ERISA"),
                                          or a "plan" as defined in and subject to Section
                                          4975 of the Internal Revenue Code (the
                                          "Code") (each such employee benefit plan or
                                          plan, a "Plan").  Section 406 of ERISA and
                                          Section 4975 of the Code prohibit certain
                                          transactions involving assets of a Plan with
                                          persons who are "parties-in-interest" (within the
                                          meaning of Section 3(14) of ERISA) or
                                          "disqualified persons" (within the meaning of
                                          Section 4975 of the Code) with respect to such
                                          Plan.  Violations of these prohibited transaction
                                          rules can result in excise taxes and other
                                          liabilities.  An investment in a Certificate by or
                                          on behalf of a Plan will cause the Certificate to
                                          be treated as an asset of the Plan for purposes of
                                          Title I of ERISA and Section 4975 of the Code.
                                          Therefore, a Certificate may not be purchased
                                          by a Plan if PaineWebber, the Depositor, the
                                          Trustee, the Corporate Obligor of the related
                                          Bonds, or any of their respective affiliates is a
                                          party-in-interest or a disqualified person with
                                          respect to the Plan, unless a prohibited
                                          transaction exemption applies and the conditions
                                          thereof are satisfied.  In addition, unless the
                                          Certificate is a "publicly-offered security" within
                                          the meaning of a final regulation issued by the
                                          Department of Labor (the "DOL Regulation")
                                          or another exception set forth in the DOL
                                          Regulation applies to the Certificates, an
                                          investment in a Certificate by a Plan may cause
                                          the underlying assets of the Trust to which such
                                          Certificate relates (i.e., the related Bonds) to
                                          also be treated as assets of such Plan for
                                          purposes of Title I of ERISA and Section 4975
                                          of the Code.  If the underlying assets of the
                                          Trust are so treated as Plan assets, the Plan's
                                          investment in the Certificate and certain
                                          transactions relating to the underlying assets of
                                          the Trust could violate the prohibited
                                          transaction rules under ERISA and the Code.  It
                                          is anticipated that certain classes of Certificates
                                          within a series of Certificates may qualify as
                                          publicly-offered securities under the DOL
                                          Regulation.  Whether a particular Certificate is
                                          expected to qualify as a publicly-offered security
                                          under the DOL Regulation will be specified in
                                          the Prospectus Supplement concerning such

                                          Certificate, if applicable.  If a Certificate is not
                                          a publicly-offered security and no other
                                          exception set forth in the DOL Regulation
                                          applies to the Certificate, then a Certificate may
                                          not be purchased by a Plan unless a prohibited
                                          transaction exemption applies to the purchase of
                                          the Certificate and the transactions relating to
                                          the underlying assets of the related Trust and the
                                          conditions of such exemption are satisfied.  It is
                                          uncertain whether the existing prohibited
                                          transaction exemptions would apply to all
                                          transactions involving the underlying assets of
                                          the Trust.  Accordingly, fiduciaries of Plans
                                          considering the purchase or holding of
                                          Certificates by or on behalf of a Plan should
                                          consult their counsel prior to making such a
                                          purchase.  See "Certain ERISA Considerations"
                                          herein and in the related Prospectus

Rating of the Certificates..............  It is a condition to the issuance of each series of
                                          Certificates that they be rated investment grade,
                                          that is, in one of the four highest rating
                                          categories (without taking into account any
                                          subcategories) by at least one nationally
                                          recognized statistical rating organization (the
                                          "Rating Agency").  The ratings applicable to the
                                          Certificates of each series will be as set forth in
                                          the related Prospectus Supplement.

                                          A security rating should be evaluated
                                          independently of similar ratings of different
                                          types of securities.  A rating is not a
                                          recommendation to buy, sell or hold securities
                                          and may be subject to revision or withdrawal at
                                          any time by the assigning rating organization.
                                          There can be no assurance that a rating will not
                                          be lowered or withdrawn by a rating
                                          organization if circumstances so warrant.

                                   THE TRUSTS

GENERAL

      With respect to each series of Certificates, the Depositor will establish
a Trust by depositing the Trust Property (as defined below) in the Trust without
recourse. After the Issuance Date with respect to each Trust, such Trust will
not purchase or otherwise acquire any additional securities and will not dispose
of or create any lien on its assets, other than upon termination of the Trust.

      The trust property will consist of the Bonds, all monies due or received
in respect thereof, certain accounts and the proceeds thereof, in each case as
described in the related Prospectus Supplement (as so described, the "Trust
Property"). The Certificates will evidence ownership interests in the related
Trust Property.

      The location of the principal office of each Trust will be specified in
the related Prospectus Supplement.

THE TRUSTEE

      The Trustee for each Trust will be specified in the related Prospectus
Supplement. The Trustee's liability in connection with the issuance and sale of
the Certificates is limited solely to the express obligations of such Trustee
set forth in the related Trust Agreement. A Trustee may resign at any time, in
which event the Depositor will be obligated to appoint a successor trustee. Any
resignation or removal of a Trustee and appointment of a successor trustee will
not become effective until acceptance of the appointment by the successor
trustee.

      The Trust Agreement will provide that the Trustee must comply with Section
310(b) of the Trust Indenture Act of 1939, as amended (the "TIA"), provided that
there will be excluded from the operation of TIA Section 310(b)(1) any series
trust deposit agreements under which other securities are outstanding evidencing
ownership interests in bonds of the Corporate Obligor of the Bonds if the
requirements for exclusion set forth in TIA Section 310(b)(1) are met.

      The Trust Agreement will provide that, except during the continuance of an
event of default on the Bonds, the Trustee will perform only such duties as are
specifically set forth in the Trust Agreement. During the existence of an event
of default on the Bonds, the Trustee will be required to exercise the rights and
powers vested in it by the Trust Agreement and use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

OFFICE FOR REGISTRATION OF TRANSFER AND EXCHANGE

      The designated office of the Trustee for the registration of transfer or
exchange of Certificates is 114 West 47th Street, New York, NY 10036-1532.
Notwithstanding the foregoing, under the DTC Book Entry Only System, transfers
and exchange of Certificates will be accomplished as described under "The Trust
Certificates--DTC Book Entry Only System" in the Prospectus Supplement.

      Any holder presenting Certificates for surrender or registration of
transfer or exchange may be required to pay any applicable service charge of the
Trustee and a sum sufficient for reimbursement of


                                       10
<PAGE>   32
any tax or governmental charge, to file such proof of residence, or other
matters or information, to execute such certificates and to make such
representations and warranties and such assurances, including a signature
guaranty, as the Trustee may reasonably deem necessary or proper. The Trustee
may withhold the delivery or delay the surrender of a registration of transfer
or exchange of any Certificates until such payment is made and proof or other
information is filed, such certificates are executed or such representations and
warranties are made.


                                    THE BONDS

GENERAL

      The Bonds to be purchased by each Trust will be debt securities issued by
a corporation or corporations (each such corporation, a "Corporate Obligor")
eligible to offer and sell securities registered on a registration statement on
Form S-3 promulgated under the Securities Act of 1933, as amended (the "Act"),
which Corporate Obligor will also be a reporting company under Section 12 or
Section 15(d) of the Securities Exchange Act of 1934 at the time the Bonds are
deposited in the Trust. Each of the Bonds will have originally been issued in a
transaction registered pursuant to the Act. The Bonds will be purchased by the
Trust from the Depositor. The Bonds will have been acquired by the Depositor
from PaineWebber Incorporated ("PaineWebber"). PaineWebber will have previously
purchased the Bonds in the secondary market. PaineWebber will not have purchased
the Bonds from the issuer thereof or any of its affiliates, and the Bonds will
not have been purchased by PaineWebber as part of the initial distribution
thereof. The specific terms and conditions of the Bonds to be purchased by each
Trust will be set forth in the related Prospectus Supplement.


             AVAILABLE INFORMATION REGARDING THE CORPORATE OBLIGORS

      The Corporate Obligors will be corporations that at the time of deposit of
Bonds into a Trust are subject to the information requirements of the Securities
Exchange Act of 1934 and in accordance therewith file reports and other
information with the Commission. Such reports, proxy and information statements
and other information filed by the Corporate Obligors with the Commission can be
inspected and copied at the public reference facilities maintained by the
Commission at its Public Reference Section, 450 Fifth Street, N.W., Washington,
D.C. 20549, and at its Regional Offices located at: Chicago Regional Office,
Citicorp Center, 500 West Madison Street, Chicago, Illinois 6066; and New York
Regional Office, Seven World Trade Center, New York, New York 10048. Copies of
such materials can also be obtained electronically through the Commission's
Internet Web Site (http://www.sec.gov). If the Bonds are listed on the New York
Stock Exchange, the material described above and other information with respect
to the Corporate Obligor will also be available for inspection at the offices of
the New York Stock Exchange at 20 Broad Street, New York, New York.

BONDHOLDER COMMUNICATIONS

      Upon the receipt by the Trustee of any bondholder communications from a
Corporate Obligor, the Trustee will transmit such communications to the
beneficial owners of the Certificates (each, a "Certificateholder") upon receipt
from the Corporate Obligor of assurances that the Trust's reasonable expenses
will be reimbursed by the Corporate Obligor. In addition, upon receipt by the
Trustee of bondholder communications from a third party (other than the
Corporate Obligor), the Trustee will transmit such bondholder communications
only to the Certificateholders upon receipt from such third


                                       11
<PAGE>   33
party of assurances that the Trustee's reasonable expenses will be reimbursed by
such third party. In either case, if the Trustee does not receive such
assurances, then the Trustee, at the sole discretion of the Depositor and at the
expense of the Trust, will transmit or cause to be transmitted any such
bondholder communications to such Certificateholders.


                                 USE OF PROCEEDS

      The entire net proceeds received by the Trust from the sale of the Trust
Certificates will be used to acquire the Bonds from the Depositor, which will
use such proceeds to acquire the Bonds from PaineWebber. Thus, neither the Trust
nor the Depositor is expected to receive any net cash proceeds from the sale of
the Trust Certificates.


                                  THE DEPOSITOR

      The Depositor, a wholly owned indirect subsidiary of PaineWebber, was
incorporated in the state of Delaware on November 22, 1993. The Depositor is
organized for the limited purpose of acquiring Bonds from PaineWebber, forming
Trusts, transferring Bonds to the Trusts, and engaging in related activities.
The assets of the Depositor and its affiliates are not available to satisfy
obligations of any Trust. The principal executive offices of the Depositor are
located at 1285 Avenue of the Americas, New York, New York 10019.


                                THE CERTIFICATES

GENERAL

      With respect to each Trust, the Certificates will be issued pursuant to
the terms of a Trust Agreement, a form of which has been filed as an exhibit to
the Registration Statement of which this Prospectus forms a part. The terms and
conditions of the Certificates include those stated in the Trust Agreement and
those made part of the Trust Agreement by reference to the TIA. The Certificates
are subject to all such terms and conditions, and reference is made to the Trust
Agreement and the TIA for a statement thereof. The following summary does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, all of the provisions of the Certificates and the Trust Agreement.
Where particular provisions or terms used in the Trust Agreement are referred
to, the actual provisions (including definitions of terms) are incorporated by
reference as part of this summary.

      Each class of Certificates of a series of Certificates issued in
book-entry form will initially be represented by a single Certificate registered
in the name of DTC. The Certificates will be available for purchase in minimum
denominations of $25 and integral multiples of $25 in excess thereof. The
Depositor has been informed by DTC that DTC's nominee will be Cede. Accordingly,
Cede is expected to be the holder of record of the Certificates issued in
book-entry form. For Certificates initially issued in book-entry form, unless
and until Definitive Certificates are issued under the limited circumstances
described herein, no Certificateholder will be entitled to receive a physical
certificate representing a Certificate. All references herein to actions by
Certificateholders refer to actions taken by DTC upon instructions from the
Participants and all references herein to distributions, notices, reports and
statements to Certificateholders refer to distributions, notices, reports and
statements to DTC or Cede, as the registered holder of the Certificates, as the
case may be, for distribution to


                                       12
<PAGE>   34
Certificateholders in accordance with DTC's procedures with respect thereto. See
"Certain Information Regarding the Certificates -- Book-Entry Registration" and
"-- Definitive Certificates."

DISTRIBUTIONS OF INTEREST AND PRINCIPAL AMOUNT

      The timing, priority, amount, allocation and/or rate of distributions on
the Certificates of each class of any series will be described in the related
Prospectus Supplement. Distributions of interest and principal on the
Certificates will be made on the dates specified in the related Prospectus
Supplement. Interest on the Certificates will be calculated as specified in the
related Prospectus Supplement, which may be on the basis of a 360-day year
consisting of twelve 30-day months or on some other basis.


                 CERTAIN INFORMATION REGARDING THE CERTIFICATES

BOOK-ENTRY REGISTRATION

      DTC is a limited purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York UCC and a "clearing agency"
registered pursuant to Section 17A of the Exchange Act. DTC was created to hold
securities for its Participants and to facilitate the clearance and settlement
of securities transactions between Participants through electronic book-entries,
thereby eliminating the need for physical movement of certificates (such
electronic book-entry system, the "DTC Book Entry Only System"). Participants
include securities brokers and dealers, banks, trust companies and clearing
corporations. Indirect access to the DTC Book Entry Only System also is
available to others such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a Participant, either
directly or indirectly ("Indirect Participants").

      Certificateholders of book-entry Certificates that are not Participants or
Indirect Participants but desire to purchase, sell or otherwise transfer
ownership of, or other interests in, such Certificates may do so only through
Participants and Indirect Participants. In addition, such Certificateholders
will receive all distributions of principal and interest through DTC
Participants. DTC will forward such payments to its Participants, which
thereafter will forward them to Indirect Participants or such
Certificateholders. Except for the Depositor, it is anticipated that the only
"Certificateholder" will be Cede, as nominee of DTC. Certificateholders will not
be recognized by the Trustee as Certificateholders as such term is used in the
Trust Agreement, and Certificateholders will be permitted to exercise the rights
of Certificateholders only indirectly through DTC and its Participants.

      Under the rules, regulations and procedures creating and affecting DTC and
its operations (the "Rules"), DTC is required to make book-entry transfers of
Certificates among Participants on whose behalf it acts with respect to the
Certificates and to receive and transmit distributions of principal of and
interest on Certificates. Participants and Indirect Participants with which
Certificateholders have accounts with respect to the Certificates similarly are
required to make book-entry transfers and receive and transmit such payments on
behalf of their respective Certificateholders. Accordingly, although
Certificateholders will not possess Certificates, the Rules provide a mechanism
by which beneficial owners will receive payments and will be able to transfer
their Certificate interests.

      The Physical Certificates delivered to the Trustee will be registered in
the name of Cede, as nominee for DTC. The Owners, as purchasers of Certificates
under the DTC Book Entry Only System, will not receive physical certificates
representing their Certificates. Instead, the ownership interests


                                       13
<PAGE>   35
of the Owners will be recorded, directly or indirectly, through the records of
the respective Participants and Indirect Participants. Transfers among Owners
will be accomplished through and reflected on the records of DTC and the
Participants or Indirect Participants of which those Owners are customers. DTC
will maintain records for the payment, transfer and exchange of Certificates
held by DTC Participants on behalf of Owners, but will not make payments
directly to Owners or record specific transfers of Certificates from one Owner
to another.

      Payments on the Bonds that are received by the Trustee from the Issuer,
including payments upon redemption of the Bonds, will be paid to DTC as the
registered holder of the related Certificates. DTC, under its current practices,
would credit those payments to the accounts of the Participants in accordance
with their respective holdings of Certificates as shown on DTC's records.
Payments by Participants and Indirect Participants to Owners will be governed by
standing instructions and customary practices, and will be the responsibility of
each such Participant or Indirect Participant and not of DTC or the Trustee,
subject to any statutory and regulatory requirements as may be in effect from
time to time.

      With respect to any Certificate, on or after each interest payment date,
if the Corporate Obligor will have paid in full and the Trustee will have
received the interest payment due on such interest payment date on the Bonds,
the Trustee will pay to DTC as the registered holder of the Certificate as of
the applicable record date, in lawful money of the United States of America, by
credit of same day funds to the account of DTC, the entire amount of such
interest payment, less any taxes or governmental charges required to be withheld
from such payment by the Trustee.

      With respect to any Certificate, if the Corporate Obligor will have paid
in full and the Trustee will have received the principal due upon maturity of
the underlying Bond, or if the Corporate Obligor will have paid in full and the
Trustee will have received the principal and redemption premium, if any, payable
upon the earlier redemption of such Certificate, the Trustee will pay to DTC as
the registered holder of the Certificates as of the applicable record date, in
lawful money of the United States of America, by credit of same day funds to the
account of DTC, the entire amount of such principal and premium, if any, less
any taxes or governmental charges required to be withheld from such payment by
the Trustee.

      Amounts received by the Trustee before 2:00 p.m. on any day will be
credited to DTC that same day. Amounts received by the Trustee after 2:00 p.m.
will be credited to DTC on the next business day.

      DTC may determine to discontinue the DTC Book Entry Only System with
respect to the Certificates at any time by giving notice to the Trustee and the
Depositor and discharging its responsibilities with respect thereto. In
addition, the Depositor may cause the removal of DTC (or a successor or
substitute depository) if the Depositor determines such removal is in the best
interests of the Owners or is in the best interests of the Depositor as long as
the removal will not adversely affect the Owners. If DTC (or a successor or
substitute depository) is removed and the Depositor, after a good faith effort,
is unable to procure the services of a successor depository, the Trustee will
serve as depository of the Bonds.

      Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a
Certificateholder to pledge Certificates to persons or entities that do not
participate in the DTC system, or to otherwise act with respect to such
Certificates, may be limited due to the lack of a physical certificate for such
Certificates.


                                       14
<PAGE>   36
      DTC has advised the Depositor that it will take any action permitted to be
taken by a Certificateholder under the related Trust Agreement only at the
direction of one or more Participants to whose accounts with DTC the
Certificates are credited. DTC may take conflicting actions with respect to
other undivided interests to the extent that such actions are taken on behalf of
Participants whose holdings include such undivided interest.

      Except as required by law, the Trustee will not have any liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interest of the Certificates of any series held by Cede, as nominee
for DTC, or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

DEFINITIVE CERTIFICATES

      Certificates may be issued in book-entry or in Definitive Certificate
form. Certificates initially issued in book-entry form will be issued in fully
registered, certificated form ("Definitive Certificates") to Certificateholders
or respective nominees, rather than to DTC or its nominee, only if (i) the
Depositor advises the appropriate trustee in writing that DTC is no longer
willing or able to discharge properly its responsibilities as depository with
respect to such Certificates and the Depositor is unable to locate a qualified
successor, (ii) the Depositor, at its option, elects to terminate the book-entry
system through DTC (iii) after the occurrence of an Event of Default, holders
representing at least a majority of the voting rights relating to the
outstanding Certificates advise the appropriate trustee through DTC in writing
that the continuation of a book-entry system through DTC (or a successor
thereto) is no longer in the best interest of the holders of such securities, or
(iv) under the circumstances described under "--Termination of Book-Entry
Registration in Connection with Suspension of Exchange Act Reporting by
Corporate Obligor" below.

      Upon the occurrence of any event described in the immediately preceding
paragraph, the Trustee will be required to notify DTC of its intent to make
Definitive Certificates available. Upon surrender by DTC of the Physical
Certificates representing the securities and receipt of instructions for
re-registration, the Trustee will reissue such securities as Definitive
Certificates to the holders thereof.

      Distributions of principal of, and interest on, the Definitive
Certificates will thereafter be made in accordance with the procedures set forth
in the related Trust Agreement directly to holders of Definitive Certificates in
whose names the Definitive Certificates were registered at the close of business
on the day before the related Payment Date. Such distributions will be made by
check mailed to the address of such holder as it appears on the register
maintained by the Trustee. The final payment on any Definitive Certificate,
however, will be made only upon presentation and surrender of such Definitive
Certificate at the office or agency specified in the notice of final
distribution to the holders of such class.

      Definitive Certificates will be transferable and exchangeable at the
offices of the Trustee or of a registrar named in a notice delivered to holders
of Definitive Certificates. No service charge will be imposed for any
registration of transfer or exchange, but the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge imposed in
connection therewith.

DEFAULTS AND REMEDIES

      With respect to each Trust, the Trust Agreement will provide that if there
is an event of default (as defined in the indenture for the Bonds) with respect
to the Bonds and such event of default is known to the Trustee, the Trustee will
promptly give notice to DTC or, if the Certificates are not then held by DTC or
any other depository, directly to the registered holders of the Certificates
then outstanding and unpaid as provided in the Trust Agreement (and in the
manner and to the extent provided in TIA Section 313(c)) within ninety days
after such event of default occurs. Such notice will set forth (a) the identity
of the issue of Bonds, (b) the date and nature of such default, (c) the face
amount of the interest or principal in default, (d) the identifying numbers of
the class of Certificates, or any combination, as the case may be, evidencing
the interest or principal described in the preceding clause, if applicable, and
(e) any other information that the Trustee may deem appropriate. Except in the
case of a default in the payment of principal or interest, the Trustee may
withhold the notice to holders of Certificates if and so long as a committee of
its responsible officers in good faith determines that withholding the notice is
in the interests of the holders of the Certificates.

      With respect to each Trust, the Trust Agreement will provide that if (a)
default is made in the payment of any interest on any Bond when due and payable
continue for the period specified in the indenture for the Bonds (or, if no such
period is specified, five days), or (b) default is made in the payment of the
principal of or any installment of the principal of any Bond when due and
payable continue for the period specified in the indenture for the Bonds (or, if
no such Period is specified, thirty days), in each case after receipt by the
Corporate Obligor of notice thereof from the Trustee or receipt by the Corporate
Obligor and the Trustee of notice thereof from holders of outstanding
Certificates representing at least twenty five percent of the voting rights with
respect to the Certificates, and the Corporate Obligor shall, after demand of
the Trustee, fail to pay the Trustee the whole amount due and payable on the
Bonds for Principal and interest, then the Trustee, in its own name and as
trustee of an express trust, subject to provision being made for indemnification
against costs, expenses and liabilities in a form satisfactory to the Trustee,
will institute a proceeding for the collection of the sums so due and unpaid,
and will prosecute such proceeding to judgment or final decree or settlement,
and will enforce the same against the Corporate Obligor or other obligor upon
the Bonds and collect in the manner provided by law out of the property of the
Corporate Obligor or other obligor upon the Bonds, whenever situated, the moneys
adjudged or decreed to be payable, unless otherwise directed by holders of
outstanding Certificates representing not less than a majority of the voting
rights.

      In the event the Trustee receives money or other property in respect of
the Bonds (other than scheduled payments) as a result of a payment default on
the Bonds, the Trustee will promptly give notice as provided in the Trust
Agreement to DTC, or for any Certificates that are not then held by DTC or any
other depository, directly to the registered holders of the Certificates then
outstanding and unpaid. Such notice will state that, not later than thirty days
after the receipt of such moneys or other property, the Trustee will distribute
such moneys or other property to the holders of the outstanding Certificates pro
rata by face amount or, if there is more than one class of Certificates under
the Trust Agreement, in proportion to the accreted value of each class of
outstanding Certificates, and within each class pro rata by face amount.

      Interest and principal payments and premium, if any, on the Bonds, are
payable solely by the Corporate Obligor.

      The Bonds may be or become subject to laws permitting bankruptcy,
moratorium, reorganization or other actions that, in the event of financial
difficulties of the Corporate Obligor, could


                                       16
<PAGE>   38
result in delays in payment or in nonpayment of the Certificates related to a
Bond. In such cases, the treatment accorded certain classes of Certificates may
be less favorable than the treatment accorded other classes of Certificates.

      Holders of Certificates will have no recourse against the Depositor or the
Trustee for payment defaults on the Bonds.

      The Depositor will be required to furnish to the Trustee not less than
annually a statement as to the performance by the Depositor of its obligations
under the Trust Agreement and as to any default in such performance.

ISSUANCE AND DELIVERY

      With respect to each Trust, the Trust Agreement will provide that the
Depositor will, by book-entry credit or otherwise, irrevocably deliver or cause
to be delivered the Bonds to the Trustee and, concurrently therewith, the
Trustee will execute and deliver to the Depositor, or such person or persons as
the Depositor may designate by written instruction, the classes of Certificates
identified in the Trust Agreement, evidencing the aggregate amount, in
authorized denominations, of the Bonds so delivered to the Trustee. No
Certificate will be entitled to the benefits of the Trust Agreement or be valid
or obligatory for any purpose unless it shall have been executed manually by the
Trustee by the signature of a duly authorized signatory.

TERMINATION OF TRUST AGREEMENT

      With respect to each Trust, the Trust Agreement will terminate one year
following the payment upon maturity (or any earlier redemption) by the
respective Corporate Obligor(s) of the entire principal amount (and any
redemption premium) of the Bonds or, in the event of a default on the Bonds, one
year following receipt by the holders of the Certificates of all amounts that
they are entitled to receive in such a case pursuant to the Trust Agreement.
Upon termination of the Trust Agreement, the Depositor will be discharged from
all obligations under the Trust Agreement (other than with respect to certain
expenses of the Trustee).

REPORTS TO CERTIFICATEHOLDERS

      Within the prescribed period of time for tax reporting purposes after the
end of each calendar year during the term of each Trust, the Trustee will mail
to each person who at any time during such calendar year has been a
Certificateholder with respect to such Trust and received any payment thereon a
statement containing certain information for the purposes of such
Certificateholder's preparation of federal income tax returns. See "Certain
Federal Income Tax Considerations."

ACCOUNTS

      With respect to each Trust, there will be established and maintained with
the Trustee one or more trust accounts, in the name of the Trustee on behalf of
the Certificateholders, into which all payments made on or with respect to the
related Bonds will be deposited.


                                       17
<PAGE>   39
DISTRIBUTIONS

      With respect to each Trust, beginning on the Payment Date specified in the
related Prospectus Supplement, distributions of principal and interest on each
series of Certificates entitled thereto will be made by the Trustee to the
Certificateholders. The timing, calculation, allocation, order, source,
priorities of and requirements for all payments to each class of
Certificateholders will be set forth in the related Prospectus Supplement.

TERMINATION OF BOOK-ENTRY REGISTRATION IN CONNECTION WITH SUSPENSION OF EXCHANGE
ACT REPORTING BY CORPORATE OBLIGOR

      Subsequent to the deposit of its Bonds into a Trust, a Corporate Obligor
which has no class of security listed on a national securities exchange or held
of record by 300 or more holders could elect to suspend its Exchange Act
reporting requirements. In such event, such Corporate Obligor would no longer be
required to make available under the Exchange Act the public information
referred to under the caption "Available Information Regarding the Corporate
Obligors". The Depositor will cause each Trust to undertake to provide, in the
Trust's own Exchange Act reports for as long as such reports are required to be
filed, quarterly and annual financial statements and other information of the
type required to be filed on Form 8-K under the Exchange Act with respect to any
Corporate Obligor which suspends its Exchange Act reporting requirements, to the
extent such reports and information are then available to the Trust.

      If such financial statements are not available to the Trust, then, unless
the Trust has earlier suspended its own Exchange Act reporting requirements for
the Certificates of such series, the Certificates of such series will, by their
terms, generally be required to be removed from the DTC book entry system, and
definitive physical certificates representing the Certificates of such series
will be issued to the beneficial owners of the Certificates of such series.
Furthermore, the Corporate Obligor for the Bonds will be notified that the Bonds
are held pursuant to the Trust Agreement and that the holders of the
Certificates constitute record holders of the Bonds. The issuance of such
definitive physical certificates representing the Certificates is intended to
increase the likelihood that there will then be more than 300 holders of record
of the Bonds, requiring the Corporate Obligor to resume filing Exchange Act
reports, in light of Rule 12g5-1(b)(1) under the Exchange Act, which appears to
require a Corporate Obligor with actual knowledge that its Bonds are held
pursuant to a Trust Agreement to treat holders of record of certificates or
other evidences of interest issued by the Trust as holders of record of the
underlying Bonds.

                    CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

      The following is a general summary of certain federal income tax
consequences of the purchase, ownership and disposition of Certificates. This
summary is based on the Internal Revenue Code of 1986, as amended (the "Code"),
as well as final, temporary and proposed Treasury regulations and administrative
and judicial decisions. Legislative, judicial and administrative changes may
occur, possibly with retroactive effect, affecting the accuracy of the
statements set forth herein.

      This summary does not purport to address all federal income tax matters
that may be relevant to every investment in Certificates. For example, it deals
only with Certificates held as capital assets within the meaning of Section 1221
of the Code. It does not address tax consequences that may be relevant to
particular holders subject to special treatment under federal income tax law
(e.g., banks and other financial institutions, life insurance companies, dealers
in securities or currencies, tax-exempt


                                       18
<PAGE>   40
entities, taxpayers holding Certificates as a hedge, or whose "functional
currency" is not the United States dollar). Except as indicated, this summary is
directed to prospective purchasers in the initial offering described herein, and
not to subsequent purchasers of Certificates. Consequently, purchasers of
Certificates should consult their own tax advisors concerning the tax
consequences to them under federal income tax law, as well as the tax law of any
state, local or foreign jurisdiction, of the purchase, ownership and disposition
of Certificates.

CLASSIFICATION OF THE TRUST

      Upon the issuance of each series of Certificates, Sidley & Austin will
deliver an opinion to the effect that the Trust will be classified as a grantor
trust under subpart E, Part I of subchapter J of the Code and not as a
partnership or an association taxable as a corporation. As a result of such
classification, each Certificateholder will be treated for federal income tax
purposes as an owner of an undivided beneficial ownership interest in all or a
portion of the Trust assets consisting of the Bonds. As a grantor trust, the
Trust will not be subject to federal income tax, although holders of
Certificates will be subject to the tax treatment discussed below.

TAXATION OF CERTIFICATEHOLDERS

      TRUST ASSETS, INCOME AND EXPENSE

      Each Certificateholder will be treated as owning an undivided interest in
all or specified assets of the Trust. As such, each Certificateholder will be
required to report on its federal income tax return its pro-rata share of the
entire gross income from such assets for the period during which it owns a
Certificate, generally in accordance with such holder's applicable method of tax
accounting. Because of stripped interests, market discount or original issue
discount ("OID"), or premium, the amounts includible in income on account of an
investment in a Certificate may differ significantly from the amounts
distributable thereon.

      Consistent with its applicable method of tax accounting, a
Certificateholder will be entitled to deduct its pro-rata share of fees paid or
incurred by the Trust. Certificateholders who are individuals, estates or trusts
will be allowed to deduct such fees subject to various limitations on itemized
deductions.

      INTEREST, DISCOUNT AND PREMIUM

      For purposes of the following discussion, a Certificate representing an
interest in the principal of Bonds comprising a Trust together with all interest
payable thereon is referred to as an "Unstripped Certificate." A Certificate
representing an undivided interest in the principal of Bonds comprising a Trust
but less than all interest payable thereon is a "Stripped Bond Certificate"
(including Certificates so denominated in the Prospectus Supplement as well as
those denominated "Principal Certificates" therein), a Certificate representing
solely an interest in interest payable on Bonds is a "Stripped Coupon
Certificate" (including Certificates so denominated in the Prospectus Supplement
as well as those denominated "Coupon Certificates" therein) and such
Certificates collectively are "Stripped Certificates."


                                       19
<PAGE>   41
      UNSTRIPPED CERTIFICATES

      A purchaser of an Unstripped Certificate generally will be required to
report its share of the interest income on Bonds in accordance with such
purchaser's applicable method of tax accounting. Such purchaser also generally
will be required to report its share of OID to the extent the Certificate
evidences an interest in Bonds issued with OID. A Certificateholder required to
report OID in income must do so although no cash attributable to such discount
will be received until a later date.

      The amount treated as OID attributable to a Bond generally is equal to the
excess of its "stated redemption price" over its "issue price." The stated
redemption price of a Bond generally is the aggregate amount payable thereunder
excluding any "qualified stated interest," i.e., interest payable
unconditionally at least annually at a single fixed or qualifying variable rate.
The Depositor anticipates that all interest payable on Bonds will be qualified
stated interest. The amounts payable (including interest and redemption premium,
as applicable) with respect to a callable Bond are determined with reference to
the call or maturity date and call price that produces the lowest yield. The
issue price of a Bond generally is the initial offering price at which a
substantial amount of that particular class of Bonds was sold.

      OID is includible in income on a daily basis, based on a constant yield to
maturity over the term of the related Bond. The yield to maturity of a callable
Bond is determined with reference to the call or maturity date and call price
that produces the lowest yield. The constant yield compounds at the end of each
"accrual period," within which OID is allocated ratably to each day. The accrual
periods utilized by a purchaser must each be no longer than one year, and must
be such that each payment will occur at the beginning or end of an accrual
period. OID attributable to Bonds bearing a variable rate of interest will be
determined by assuming that such rate will remain constant from the date of
issuance, while changes in the actual rate will be accounted for in the period
to which they relate.

      OID may be reduced to the extent that an interest in a Bond issued with
OID is acquired by a purchaser of an Unstripped Certificate with "acquisition
premium." Acquisition premium is the excess of such Bond's allocable purchase
price over its "adjusted issue price," which in turn is the sum of the Bond's
issue price and previous accruals of OID. OID otherwise includible in income may
be reduced in the proportion that the acquisition premium bears to OID remaining
to be accrued on the Bond.

      To the extent that the allocable purchase price paid by a purchaser of an
Unstripped Certificate for its interest in a particular Bond exceeds the
holder's interest in such Bond's remaining principal balance, that interest will
be acquired with amortizable bond premium. The Certificateholder may elect to
amortize such premium as an offset to interest income, generally using a
constant yield method compounding over the term of the Bond. A callable Bond
will be treated for this purpose as maturing with reference to the call or
maturity date and amount, as applicable, that produces the smallest premium. Any
such election will apply to debt instruments held by the Certificateholder
during the year in which the election is made, and to all debt instruments
acquired thereafter.

      A purchaser of an Unstripped Certificate alternatively may acquire an
interest in a Bond at a "market discount," i.e., the excess of such Bond's
adjusted issue price, or its issue price in the case of a Bond issued without
OID, over its allocable purchase price. If a Certificateholder acquires an
interest in a Bond having market discount, the Certificateholder will be
required to treat any gain on the sale of a Certificate as ordinary income to
the extent of the holder's share of any previously unrecognized accrued market
discount on such Bond. Moreover, such a Certificateholder may be required to
defer a portion of its otherwise deductible interest expense allocable to
borrowings related to the Certificate


                                       20
<PAGE>   42
until disposing of the Certificate in a taxable transaction. A holder may elect
to include market discount in income currently in lieu of treating gain as
ordinary income and deferring interest deductions; any such election is
irrevocable, and applies to all market discount bonds acquired during and after
the year of election.

      STRIPPED CERTIFICATES

      A purchaser of a Stripped Principal Certificate or Stripped Interest
Certificate will be treated as having purchased an interest in the underlying
"stripped bonds" or "stripped coupons," respectively. Under the "coupon
stripping" rules of the Code, such purchasers generally will be subject to the
OID rules discussed above, and will be required to report their share of OID
with respect to each such underlying stripped bond or stripped coupon although
again no cash attributable to such discount will be received until a later date.

      The amount treated as OID attributable to a stripped bond or stripped
coupon generally is equal to the excess of the "stated redemption price" over
its allocable purchase price. In the case of a stripped bond, the stated
redemption price generally is the aggregate amount payable thereunder; the
stated redemption price of a stripped coupon is the amount payable when due. The
purchase price allocable to a stripped bond or stripped coupon will be
determined on the basis of their respective fair market values on the date of
the Certificate purchase.

      OID is includible in income on a daily basis, based on a constant yield to
maturity over the term of the related stripped bond or stripped coupon, as
applicable. The constant yield compounds at the end of each "accrual period,"
within which OID is allocated ratably to each day. The accrual periods utilized
by a purchaser must each be no longer than one year, and must be such that each
payment will occur at the beginning or end of an accrual period. OID
attributable to stripped Bonds bearing a variable rate of interest will be
determined by assuming that such rate will remain constant from the date of
stripping, while changes in the actual rate will be accounted for in the period
to which they relate. In certain circumstances the OID Regulations permit a
Certificateholder to recognize OID under a method that differs from that used by
the Trustee.

      In the case of callable stripped bonds, the amounts payable (including
interest, as applicable) and the yield to maturity are determined with reference
to the call or maturity date, as applicable, that produces the lowest yield. It
is unclear, however, whether such call or maturity date producing the lowest
yield should be determined with or without regard to interest stripped from the
stripped bond. Interest payable on a stripped bond after such date until the
final maturity or actual call date should be includible in income under the
purchaser's applicable method of tax accounting.

      The Internal Revenue Service ("IRS") could contend that certain Stripped
Principal Certificates should be treated as having amortizable bond premium, in
which case failure to make a premium amortization election could cause a holder
to recognize income from such a Certificate more rapidly. Such a failure also
could cause a holder to recognize more taxable income over the holding period,
if the holder's basis in the Certificate attributable to such premium ultimately
proved non-deductible because it resulted in capital loss. A Stripped Principal
Certificate purchased at a price in excess of its face amount and treated as
having a stated redemption price that excluded associated interest payments as
"qualified stated interest" could be so treated, producing the foregoing
possible consequences. Prospective purchasers of such Certificates should
consult their own tax advisors with regard to the advisability of a premium
amortization election.


                                       21
<PAGE>   43
      CONSTANT YIELD ELECTION

      The OID Regulations permit a Certificateholder to elect to accrue all
interest, original issue discount, market discount, and premium in income as
interest, based on a constant yield method. If a Certificateholder made this
election for a Certificate representing an interest in Bonds having market
discount, such Certificateholder would be deemed to have made an election to
currently include market discount in income with respect to all debt instruments
having market discount acquired by such Certificateholder during the taxable
year of the election or thereafter. Similarly, a Certificateholder making this
election for a Certificate representing an interest in Bonds having amortizable
bond premium would be deemed to have made an election to amortize bond premium
with respect to all debt instruments having bond premium that such
Certificateholder owns or acquires. Each of these elections would be
irrevocable; holders considering any such election should consult their own tax
advisors.

      DISPOSITION AND RETIREMENT

      Upon the sale, exchange or retirement of a Certificate, a holder will
recognize taxable gain or loss in respect of its interest in each Trust asset
underlying such Certificate. Such gains and losses generally will be long-term
capital gains and losses if the Certificate has been held for more than one
year. However, some or all gain may be treated as ordinary income (i) to the
extent of any accrued and unrecognized market discount, (ii) if a Certificate is
held as part of a "conversion transaction" as defined in Code section 1258, or
(iii) if a Certificateholder has made an election under Code section 163(d)(4)
to have net capital gains taxed as investment income at ordinary income rates.
Net long-term capital gains of individuals are subject to taxation at reduced
capital gains tax rates, whereas capital losses of all taxpayers are subject to
limited deductibility.

      Gain or loss with respect to each underlying Trust asset is equal to the
difference between the allocable amount realized and the holder's allocable
adjusted basis therein. The amount realized in respect of a disposition or
retirement of a Certificate is allocable among the underlying Trust assets in
accordance with their relative fair market values; a Certificateholder
determines its basis in each such asset by allocating its purchase price among
those assets on the basis of their relative fair market values as of the date of
purchase. A Certificateholder's basis in its Certificate and each underlying
Trust asset generally would be increased by any original issue or market
discount and decreased by any premium amortization previously taken into account
in determining the holder's taxable income, and further decreased by amounts
paid other than qualified stated interest.

      If Certificates identified as Callable Principal Certificates or Callable
Stripped Bond Certificates in any applicable Prospectus Supplement (each, the
"Callable Certificates") are retired in exchange for Bonds, the holders of such
Certificates should not recognize gain or loss with respect to their receipt of
Bonds in exchange for their interest in the Trust.

ADDITIONAL TAX CONSIDERATIONS

      BACKUP WITHHOLDING

      Payments of interest (including OID) and principal, as well as proceeds
from disposition or retirement of Certificates, may be subject to a "backup"
withholding tax of 31 percent if a recipient fails to furnish to the payor
certain identifying information. Certain penalties also may be imposed by the
IRS on a recipient of payments who is required to supply information, but fails
to do so in the proper manner.


                                       22
<PAGE>   44
      Backup withholding will not apply with respect to payments made to certain
exempt recipients, such as corporations and financial institutions. Holders
should consult their own tax advisers with respect to qualification for
exemption from backup withholding and the procedure for obtaining such an
exemption. Any amounts deducted and withheld would be allowed as a credit
against such recipient's federal income tax.

      TAX INFORMATION REPORTING

      Within a reasonable time after the end of each calendar year, the Trustee
will furnish each Certificateholder (DTC or other holders of definitive
Certificates) such customary information as the Trustee deems necessary or
desirable to enable Certificateholders to prepare their tax returns. The Trustee
will furnish comparable information to the IRS as and when required by law to do
so. Because the rules for accruing discount and amortizing premium with respect
to Certificates are uncertain in various respects, there is no assurance that
the IRS will agree with information reports of such items of income and expense.
Moreover, even if otherwise accepted as accurate by the IRS, such information
reports will be based on the original issue price of the Certificates, and in
the case of Certificateholders who purchased their Certificates after their
initial issuance or at a price different from the original issue price, those
reports will require adjustment to account for such Certificateholders' holding
periods and purchase prices. Certificateholders who hold their Certificates
through DTC participants should consult the party from whom they receive tax
reports concerning the Certificates to determine whether such reports reflect
such adjustments. Certificateholders who hold definitive Certificates should
consult their tax advisors concerning the method for making any such required
adjustments.

      NON-UNITED STATES HOLDERS

      A Non-United States Holder is a beneficial owner of a Certificate other
than a United States citizen or resident, a domestic partnership or corporation,
or a trust or estate subject to U.S. income tax on income regardless of its
source. Under present federal income and estate tax law:

            (a)   No withholding of federal income tax will be required with
                  respect to the payment of interest or OID attributable to a
                  Certificate owned by a Non-United States Holder, provided that
                  such holder (i) does not actually or constructively own 10
                  percent or more of any issuer of Bonds, (ii) is not a
                  controlled foreign corporation related to any such issuer, and
                  (iii) in accordance with specified procedures, supplies the
                  person otherwise required to withhold with a certification to
                  the effect that the beneficial owner is not a United States
                  person, citizen or resident. In certain circumstances, the
                  requisite certification may be provided by or through a bank
                  or other financial institution.

            (b)   No withholding of federal income tax will be required with
                  respect to any gain realized by a Non-United States Holder
                  upon the sale, exchange or retirement of a Certificate, except
                  gains realized by certain nonresident alien individuals
                  present in the United States for 183 days or more during the
                  taxable year.

            (c)   A Certificate beneficially owned by an individual who at the
                  time of death is a Non-United States Holder will not be
                  subject to federal estate tax as a result of such individual's
                  death, provided that the payments with respect to such


                                       23
<PAGE>   45
                  Certificate are not effectively connected with a United States
                  trade or business of such individual.

      Notwithstanding the foregoing, Non-United States Holders may be subject to
income tax withholding and estate taxation with respect to any Bonds that were
issued before July 19, 1984. Further, a Non-United States Holder engaged in a
trade or business within the United States whose income from a Certificate is
effectively connected with that trade or business generally will be subject to
regular United States federal income tax on such income and gain in the same
manner as if it were a United States holder. In addition, if such a Non-United
States Holder is a foreign corporation, it may be subject to a branch profits
tax equal to 30 percent of its effectively connected earnings and profits for
the taxable year, subject to adjustments.

       Backup withholding will not apply to payments on a Certificate to a
Non-United States Holder if the holder has certified as to its foreign status
under penalty of perjury (or has otherwise established an exemption) and certain
other requirements are met. Payments on the sale, exchange or other disposition
of a Certificate to or through a foreign office of a broker will not be subject
to back-up withholding; payments to or through the United States office of a
broker will be subject to backup withholding unless the Non-United States Holder
makes the certification or otherwise establishes an exemption under the
conditions previously described.

      Non-United States Holders should consult their own tax advisors regarding
the application of United States federal income tax law to their particular
situations.

STATE AND OTHER TAX CONSIDERATIONS

      In addition to the federal income tax consequences described above,
potential investors should consider the state, local and foreign tax
consequences of the acquisition, ownership and disposition of Certificates.
State, local and foreign tax law may differ substantially from federal tax law,
and this discussion does not purport to describe any aspect of the tax law of a
state or other jurisdiction. Therefore, prospective purchasers should consult
their own tax advisors with respect to such matters.

                          CERTAIN ERISA CONSIDERATIONS

GENERAL

      Summarized below are certain consequences under the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), and Section 4975 of the
Internal Revenue Code of 1986 (the "Code"), that a fiduciary of an "employee
benefit plan" (as defined in and subject to ERISA) or of a "plan" (as defined in
and subject to Section 4975 of the Code) who has investment discretion should
consider before deciding to invest the plan's assets in Certificates (such
"employee benefit plans" and "plans" being referred to herein as "Plans," and
such fiduciaries with investment discretion being referred to herein as "Plan
Fiduciaries"). Furthermore, all potential investors in Certificates should read
the following summary because it describes certain issues that could affect the
Trust as a consequence of Plans investing in Certificates. The following summary
is intended only to be a summary of certain issues under ERISA and Section 4975
of the Code which are likely to be raised by an investor's own counsel.

      In general, the terms "employee benefit plan" as defined in ERISA and
"plan" as defined in Section 4975 of the Code refer to any plan or account of
various types which provide retirement


                                       24
<PAGE>   46
benefits or welfare benefits to an individual or to an employer's employees and
their beneficiaries. Plans include corporate pension and profit-sharing plans,
"simplified employee pension plans," Keogh plans for self-employed individuals
(including partners in a partnership), individual retirement accounts described
in Section 408 of the Code and medical benefit plans. For the purposes of the
following discussion, the term "Plan" also includes any entity whose assets
constitute assets of any Plan for purposes of Title I of ERISA or Section 4975
of the Code as discussed in the "Plan Assets" section of this summary below, and
the term "Plan Fiduciary" includes any person who is a fiduciary with respect to
any such entity that is a Plan.

      Each Plan Fiduciary must give appropriate consideration to the facts and
circumstances that are relevant to an investment in Certificates, including the
role that an investment in Certificates plays in the Plan's investment
portfolio. Each Plan Fiduciary, before deciding to invest in Certificates, must
be satisfied that an investment in Certificates is a prudent investment for the
Plan, that the investments of the Plan, including the investment in
Certificates, are diversified so as to minimize the risks of large losses and
that an investment in Certificates complies with the Plan and related trust
documents.

      Each Plan considering acquiring Certificates should consult its own legal
and tax advisors before doing so.

EXEMPT PLANS

      ERISA and Section 4975 of the Code do not apply to governmental plans and
certain church plans, each as defined in Section 3 of ERISA and Section 4975(g)
of the Code. However, fiduciaries with respect to these plans may be subject to
federal, state or other laws similar in effect to ERISA and Section 4975 of the
Code. The discussion below does not purport to address considerations under such
federal, state or other laws.

PLAN ASSETS

      When a Plan invests in a Certificate, not only does the Certificate become
an asset of the Plan, but, unless an exception applies, the investment in a
Certificate by a Plan will cause, for purposes of Title I of ERISA and Section
4975 of the Code, the Bonds owned by the related Trust to be treated as assets
of that Plan. A regulation (the "DOL Regulation") issued under ERISA by the
United States Department of Labor (the "DOL") contains rules for determining
when an investment by a Plan in an entity (such as the Trust) will cause the
underlying assets of the entity to be treated as assets of that Plan for
purposes of Title I of ERISA and Section 4975 of the Code ("plan assets"). The
DOL Regulation provides, with respect to a Plan's purchase of an equity
interest, such as a Certificate, of an entity, that the assets of the entity
will be plan assets of the Plan unless (i) the equity interest purchased is a
"publicly-offered security" (the "Publicly-Offered Security Exception"), (ii)
the investment by all "benefit plan investors" is not "significant" (the
"Participation Exception") or (iii) certain other exceptions, not relevant here,
apply.

      The Publicly-Offered Security Exception applies if the equity interest
purchased by the Plan is a security that is (1) "freely transferable," (2) part
of a class of securities that is "widely held" and (3) either (a) part of a
class of securities registered under Section 12(b) or 12(g) of the Securities
Exchange Act of 1934, or (b) sold to the Plan as part of a public offering
pursuant to an effective registration statement under the Securities Act of 1933
and the class of which such security is a part is registered under the
Securities Exchange Act of 1934 within 120 days (or such later time as may be
allowed by the Securities and Exchange Commission) after the end of the fiscal
year of the issuer in


                                       25
<PAGE>   47
which the offering of such security occurred. The DOL Regulation states that the
determination of whether a security is "freely transferable" is to be made based
on all relevant facts and circumstances. The DOL Regulation specifies that, in
the case of a security that is part of an offering in which the minimum
investment is $10,000 or less, the following requirements, alone or in
combination, ordinarily will not affect a finding that the security is freely
transferable: (i) any requirement that not less than a minimum number of shares
or units of such security be transferred or assigned by any investor, provided
that such requirement does not prevent transfer of all of the then remaining
shares or units held by an investor; (ii) a requirement that no transfer or
assignment of the security or rights in respect thereof be made to an ineligible
or unsuitable investor; (iii) any restriction on, or prohibition against, any
transfer or assignment which would violate any state or federal statute,
regulation, court order, judicial decree or rule of law; (iv) a requirement that
no transfer or assignment be made without advance written notice being given to
the entity that issued that security; or (v) any requirement that reasonable
transfer or administrative fees be paid in connection with a transfer or
assignment. Under the DOL Regulation, a class of securities is "widely held"
only if it is of a class of securities owned by 100 or more investors
independent of the issuer and of each other, but a class of securities will not
fail to be widely-held solely because subsequent to the initial offering the
number of independent investors falls below 100 as a result of events beyond the
control of the issuer. It is anticipated that for certain series of
Certificates, one or more classes of Certificates in those series will satisfy
the Publicly-Offered Security Exception. The Prospectus Supplement for each
series of Certificates will specify whether any or all classes of Certificates
in such series are expected to satisfy the Publicly-Offered Security Exception.

      The Participation Exception applies with respect to the assets of an
entity in which a Plan purchases an equity interest if, immediately after the
most recent acquisition of any interest in the entity, less than 25% of the
value of each class of equity interests in the entity is held by "benefit plan
investors" on such date, determined by not including the investments (a) of
persons with discretionary authority or control over the assets of such entity,
(b) of any person who provides investment advice for a fee (direct or indirect)
with respect to such assets and (c) of "affiliates" (within the meaning of the
DOL Regulation) of such persons. For this purpose, the term "benefit plan
investors" includes all plans and accounts of the types described above under
"--General" as employee benefit plans or plans, whether or not subject to ERISA
or Section 4975 of the Code, as well as entities whose assets constitute plan
assets due to investments made in such entities by any such plans or accounts.
Generally, for any class or series of Certificates there is no restriction on
the percentage of the value of that class or series of Certificates that may be
owned by benefit plan investors and, thus, usually there is no assurance that
investment by benefit plan investors will not be significant. Accordingly, it is
not expected that the Participation Exception will apply with respect to any
series of Certificates.

      Therefore, unless the Prospectus Supplement for any particular series of
Certificates specifies that the Participation Exception or the Publicly-Offered
Security Exception is expected to apply to such Certificates, it should be
assumed that the Bonds owned by the Trust to which the Certificates relate will
be treated as plan assets of Plans that invest in such Certificates.

      In addition, it should be noted that ERISA and the Code may place
restrictions on the purchase of Certificates by insurance companies. In
particular, insurance companies considering the purchase of Certificates should
consult their own counsel with respect to the United States Supreme Court
decision in John Hancock Mutual Life Insurance Co. v. Harris Trust and Savings
Bank and any subsequent legislation or other guidance that has or may become
available relating to that decision, including the retroactive and prospective
exemptive relief granted by the DOL for transactions


                                       26
<PAGE>   48
involving insurance company general accounts in prohibited transaction class
exemption 95-60, Section 401(c) of ERISA and regulations issued under Section
401(c) of ERISA.

PROHIBITED TRANSACTIONS

      Section 406 of ERISA prohibits "parties in interest" with respect to a
Plan from engaging in certain transactions involving the Plan and its assets
unless a statutory or administrative exemption applies to the transaction. For
instance, Section 406 of ERISA prohibits a "party in interest" with respect to a
Plan from selling a Certificate to such Plan unless a statutory or
administrative exemption applies. In addition, if the Bonds are plan assets,
Section 406 of ERISA will prohibit the Trustee, among others, from causing the
assets of the Trust to be involved, directly or indirectly, in certain types of
transactions with "parties in interest" with respect to investing Plans unless a
statutory or administrative exemption applies. If the prohibited transaction
restrictions of Section 406 of ERISA are violated, ERISA generally provides for
civil penalties upon the Plan Fiduciary and possibly other persons. Section 4975
of the Code generally imposes an excise tax on "disqualified persons" who
engage, directly or indirectly, in similar types of transactions with the assets
of Plans subject to such Section (except that an individual retirement account
that engages in a prohibited transaction may instead forfeit its tax-exempt
status) and also requires rescission of such transactions.

      PaineWebber, the Depositor, the Trustee, the Corporate Obligor of the
Bonds owned by the Trust to which a Certificate relates, and certain other
persons and certain affiliates thereof might be considered or might become a
party in interest or disqualified person with respect to a Plan. If so, the
acquisition, holding or disposition of an investment in Certificates by or on
behalf of such Plan could give rise to one or more "prohibited transactions"
within the meaning of Section 406 of ERISA or Section 4975 of the Code unless an
exemption described below or some other exemption is available. In particular,
the sale by PaineWebber to such a Plan of a Certificate regardless of whether
the related Bonds are plan assets, and the services provided by the Trustee to
the Trust or the loans from the Trust to the issuer(s) of the related Bonds if
the related Bonds are plan assets, would appear in certain circumstances to be
prohibited transactions unless an exemption applies.

      There are numerous exemptions to the prohibited transaction restrictions
of Section 406 of ERISA and Section 4975 of the Code, and the applicability of
any particular exemption depends upon the circumstances. An investment in a
Certificate may not be purchased by or on behalf of a Plan unless (i) the
Prospectus Supplement governing the Certificate provides that the Participation
Exception or Publicly-Offered Security Exception applies to such Certificate or
(ii) a prohibited transaction exemption (such as one of the following Prohibited
Transaction Class Exemptions ("PTCEs")) applies and the conditions thereof are
satisfied:

      i.    PTCE 84-14, which provides an exemption if the purchase is made on
            behalf of the Plan by a "qualified professional asset manager." In
            general, a qualified professional asset manager is an investment
            adviser registered under the Investment Advisers Act of 1940, a
            bank, as defined in such Act or an insurance company, each of which
            meets a certain financial requirements.

      ii.   PTCE 90-1, which provides an exemption if the purchase is made on
            behalf of an insurance company pooled separate account in which the
            assets of no Plan (when aggregated with the assets of any other Plan
            maintained by the same employer or employee organization) in the
            pooled separate account exceed 10% of the total assets in the pooled
            separate account.


                                       27
<PAGE>   49
      iii.  PTCE 91-38, which provides an exemption if the purchase is made on
            behalf of a bank collective investment fund in which the interest of
            no Plan (when aggregated with the interests of any other Plan
            maintained by the same employer or employee organization) in the
            collective investment fund exceeds 10% of the total assets in the
            collective investment fund.

      iv.   PTCE 95-60, which provides an exemption if the purchase is made on
            behalf of an insurance company general account in which the reserves
            and liabilities held by no Plan (when aggregated with the reserves
            and liabilities of any other Plan maintained by the same employer,
            an affiliate thereof or the same employee organization) in the
            insurance company general account exceed 10% of the total reserves
            and liabilities of the general account plus surplus.

      v.    PTCE 96-23, which provides an exemption if the purchase is made on
            behalf of the Plan by an "in-house asset manager." In general, an
            in-house asset manager is a subsidiary of a Plan sponsor or of such
            Plan sponsor's parent corporation or a membership nonprofit
            corporation the majority of whose members are officers of a Plan
            sponsor or of such Plan sponsor's parent corporation, each of which
            meets certain financial requirements.

      The PTCEs described above contain numerous technical requirements that
must be satisfied as a condition of reliance thereon and may not provide relief
for all transactions involving the Bonds, even if they would otherwise apply to
a purchase of a Certificate by a Plan. Before purchasing a Certificate, a Plan
Fiduciary should consult with its legal counsel and determine whether there
exists any prohibition to the acquisition and continued ownership of such
Certificate. In particular, a Plan Fiduciary should determine whether
PaineWebber, the Corporate Obligor of the Bonds owned by the Trust to which the
Certificate relates, the Trustee or the Depositor are parties in interest with
respect to the Plan and whether any prohibited transaction exemptions, such as
PTCE 84-14, PTCE 90-1, PTCE 91-38, PTCE 95-60 or PTCE 96-23, apply.


INELIGIBLE PURCHASERS

      Regardless of whether the Participation Exception, the Publicly-Offered
Security Exception or the PTCEs described above apply, a Plan generally may not
purchase a Certificate if PaineWebber, the Depositor, the Trustee, the Corporate
Obligor of the related Bonds, or any of their respective affiliates either: (a)
has investment discretion with respect to the investment of such Plan assets;
(b) has authority or responsibility to give or regularly gives investment advice
with respect to such Plan assets for a fee and pursuant to an agreement or
understanding that such advice will serve as a primary basis for investment
decisions with respect to such Plan assets and that such advice will be based on
the particular investment needs of the Plan; or (c) is an employer maintaining
or contributing to such Plan.

      BY ITS PURCHASE OF A CERTIFICATE, EACH PURCHASER WILL BE DEEMED TO HAVE
REPRESENTED AND WARRANTED THAT ITS ACQUISITION AND OWNERSHIP OF SUCH CERTIFICATE
DOES NOT AND WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION UNDER ERISA
OR THE CODE AND, TO THE EXTENT THAT THE RELATED BONDS CONSTITUTE "PLAN ASSETS,"
THE TRANSACTIONS INVOLVING THE RELATED BONDS WILL NOT CONSTITUTE OR RESULT IN A
NON-EXEMPT


                                       28
<PAGE>   50
PROHIBITED TRANSACTION AS A RESULT OF SUCH PURCHASER'S ACQUISITION OR OWNERSHIP
OF SUCH CERTIFICATES.

      EACH PLAN FIDUCIARY SHOULD CONSULT WITH ATTORNEYS AND FINANCIAL ADVISORS
AS TO THE PROPRIETY OF SUCH AN INVESTMENT IN LIGHT OF THE CIRCUMSTANCES OF THE
PARTICULAR PLAN AND CURRENT TAX LAW.

                              PLAN OF DISTRIBUTION

      The Certificates offered hereby and by the related Prospectus Supplement
will be offered in series through one or more of the methods described below.
The Prospectus Supplement prepared for each series will describe the method of
offering being utilized for that series and will state the net proceeds, if any,
to the Trust or the Depositor from such sale.

      Any Certificates acquired by PaineWebber as underwriter will be acquired
by PaineWebber for its own account and may be resold from time to time in one or
more transactions, including negotiated transactions, at fixed public offering
prices or at varying prices to be determined at the time of sale or at the time
of commitment therefor. If any underwriters other than PaineWebber participate
as co-managers in the distribution of the Certificates of a particular series,
their names and PaineWebber's will be set forth on the cover of the Prospectus
Supplement relating to such series and the members of the underwriting
syndicate, if any, will be named in such Prospectus Supplement.

      In connection with any sale of the Certificates in which PaineWebber is
not the sole underwriter, the other underwriters may receive compensation from
PaineWebber or from purchasers of the Certificates in the form of discounts,
concessions or commissions. Underwriters and dealers participating in the
distribution of the Certificates may be deemed to be underwriters in connection
with such Certificates, and any discounts or commissions received by them from
PaineWebber and any profit on the resale of Certificates by them may be deemed
to be underwriting discounts and commissions under the Securities Act of 1933,
as amended.

      It is anticipated that the underwriting agreement pertaining to the sale
of any series of Certificates will provide that the obligations of the
underwriters will be subject to certain conditions precedent, that the
underwriters will be obligated to purchase all such Certificates if any are
purchased (other than in connection with an underwriting on a best efforts
basis), and that the Depositor will indemnify the several underwriters and the
underwriters will indemnify the Depositor against certain civil liabilities,
including liabilities under the Securities Act of 1933, as amended, or will
contribute to payments required to be made in respect thereof.

                                 LEGAL OPINIONS

      Certain legal matters relating to the Certificates and certain federal
income tax matters will be passed upon for the Depositor and PaineWebber by
Sidley & Austin, counsel to the Depositor and PaineWebber.
