               (p) The Company has complied with all provisions of Section

          Government of Cuba or with any person or affiliate located in Cuba.

     2. Delayed Delivery Contracts. If the Prospectus provides for sales of
Offered Securities pursuant to Delayed Delivery Contracts, the Company hereby
authorizes the Underwriters to solicit offers to purchase Contract Securities on
the terms and subject to the conditions set forth in the Prospectus pursuant to
Delayed Delivery Contracts. Delayed Delivery Contracts may be entered into only
with institutional investors approved by the Company of the types set forth in
the Prospectus. On the Closing Date, the Company will pay to the Manager as
compensation for the accounts of the Underwriters the commission set forth in
the Underwriting Agreement in respect of the Contract Securities. The
Underwriters will not have any responsibility in respect of the validity or the
performance of any Delayed Delivery Contracts.

     If the Company executes and delivers Delayed Delivery Contracts with
institutional investors, the aggregate amount of Offered Securities to be
purchased by the several Underwriters shall be reduced by the aggregate amount
of Contract Securities; such reduction shall be applied to the commitment of
each Underwriter pro rata in proportion to the amount of Offered Securities set
forth opposite such Underwriter's name in the Underwriting Agreement, except to
the extent that the Manager determines that such reduction shall be applied in
other proportions and so advises the Company; provided, however, that the total
amount of Offered Securities to be purchased by all Underwriters shall be the
aggregate amount set forth above, less the aggregate amount of Contract
Securities.

     3. Terms of Public Offering. The Company is advised by the Manager that the
Underwriters propose to make a public offering of their respective portions of
the Underwriters' Securities as soon after this Agreement has been entered into
as in the Manager's judgment is advisable. The terms of the public offering of
the Underwriters' Securities are set forth in the Prospectus.

     4. Payment and Delivery. Except as otherwise provided in this Section 4,
payment for the Underwriters' Securities shall be made to the Company in Federal
or other funds immediately available at the time and place set forth in the
Underwriting Agreement, upon delivery to the Manager for the respective accounts
of the several Underwriters of the Underwriters' Securities registered in such
names and in such denominations as the Manager shall request in writing not less
than two full business days prior to the date of delivery, with any transfer
taxes payable in connection with the transfer of the Underwriters' Securities to
the Underwriters duly paid.

     Delivery on the Closing Date of any Units that are (i) Units in bearer form
shall be effected by delivery of a single temporary Global Security (as defined
in the Trust Agreement) to a common depositary for Morgan Guaranty Trust Company
of New York, Brussels office, as operator of the Euroclear System ("Euroclear"),
and for Centrale de Livraison de Valeurs Mobilieres S.A. ("Cedel") for credit to
the respective accounts at Euroclear or Cedel of each Underwriter or to such
other accounts as such Underwriter may direct. Any Global Security shall be
delivered to the Manager not later than the Closing Date, against payment of
funds to the Company in the net amount due to the Company for such Global
Security by the method and in the form set forth in the Underwriting Agreement.
The Company shall cause definitive Units in bearer form to be prepared and
delivered in exchange for such Global Security in such manner and at such time
as may be provided in or pursuant to the Indenture; provided, however, that the
Global Security shall be exchangeable for definitive Units in bearer form only
on or after the date specified for such purpose in the Prospectus.

     5. Conditions to the Underwriters' Obligations. The several obligations of
the Underwriters are subject to the following conditions:

               (a) Subsequent to the execution and delivery of the Underwriting
          Agreement and prior to the Closing Date:

                    (i) there shall not have occurred any downgrading, nor shall
               any notice have been given of any intended or potential
               downgrading or of any review for a possible change that does not
               indicate the direction of the possible change, in the rating
               accorded any of the Company's securities by any "nationally
               recognized statistical rating organization," as such term is
               defined for purposes of Rule 436(g)(2) under the Securities Act;
               and

                    (ii) there shall not have occurred any change, or any
               development involving a prospective change, in the condition,
               financial or otherwise, or in the earnings, business or
               operations of the Company and its subsidiaries, taken as a whole,
               from that set forth in the Prospectus (exclusive of any
               amendments or supplements thereto subsequent to the date of this
               Agreement) that, in the judgment of the Manager, is material and
               adverse and that makes it, in the judgment of the Manager,
               impracticable to market the Offered Securities on the terms and
               in the manner contemplated in the Prospectus.

          (b) The Underwriters shall have received on the Closing Date a
     certificate, dated the Closing Date and signed by an executive officer of
     the Company, to the effect set forth in Section 5(a)(i) above and to the
     effect that the representations and warranties of the Company contained in
     this Agreement are true and correct as of the Closing Date and that the
     Company has complied with all of the agreements and satisfied all of the
     conditions on its part to be performed or satisfied hereunder on or before
     the Closing Date.

     The officer signing and delivering such certificate may rely upon the best
of his or her knowledge as to proceedings threatened.

          (c) An opinion, dated the Closing Date, addressed to MSDW Structured
     Asset Corp. in substantially the form attached at Exhibit A to this
     Underwriting Agreement, shall be received by the Underwriters.

     6. Covenants of the Company. In further consideration of the agreements of
the Underwriters herein contained, the Company covenants with each Underwriter
as follows:

          (a) To furnish the Manager, without charge, ___ signed copies of the
     Registration Statement (including exhibits thereto) and for delivery to
     each other Underwriter a conformed copy of the Registration Statement
     (without exhibits thereto) and to furnish the Manager in New York City,
     without charge, prior to 10:00 a.m. New York City time on the business day
     next succeeding the date of this Agreement and during the period mentioned
     in Section 6(c) below, as many copies of the Prospectus, any documents
     incorporated by reference therein and any supplements and amendments
     thereto or to the Registration Statement as the Manager may reasonably
     request.

          (b) Before amending or supplementing the Registration Statement or the
     Prospectus with respect to the Offered Securities, to furnish to the
     Manager a copy of each such proposed amendment or supplement and not to
     file any such proposed amendment or supplement to which the Manager
     reasonably objects.

          (c) If, during such period after the first date of the public offering
     of the Offered Securities as in the opinion of counsel for the Underwriters
     the Prospectus is required by law to be delivered in connection with sales
     by an Underwriter or dealer, any event shall occur or condition exist as a
     result of which it is necessary to amend or supplement the Prospectus in
     order to make the statements therein, in the light of the circumstances
     when the Prospectus is delivered to a purchaser, not misleading, or if, in
     the opinion of counsel for the Underwriters, it is necessary to amend or
     supplement the Prospectus to comply with applicable law, forthwith to
     prepare, file with the Commission and furnish, at its own expense, to the
     Underwriters and to the dealers (whose names and addresses the Manager will
     furnish to the Company) to which Offered Securities may have been sold by
     the Manager on behalf of the Underwriters and to any other dealers upon
     request, either amendments or supplements to the Prospectus so that the
     statements in the Prospectus as so amended or supplemented will not, in the
     light of the circumstances when the Prospectus is delivered to a purchaser,
     be misleading or so that the Prospectus, as amended or supplemented, will
     comply with law.

          (d) To endeavor to qualify the Offered Securities for offer and sale
     under the securities or Blue Sky laws of such jurisdictions as the Manager
     shall reasonably request.

     Company or warrants to purchase debt securities of the Company
     substantially similar to the Offered Securities (other than (i) the Offered
     Securities and (ii) commercial paper issued in the ordinary course of
     business), without the prior written consent of the Manager.

                           (f) Whether or not the transactions contemplated in
         this Agreement are consummated or this Agreement is terminated, to pay

          during the restricted period to a person who is within the United
          States or its possessions or to a United States person, except as
          permitted by the D Rules;

               (iii) if it is a United States person, it is acquiring the Debt
          Securities in bearer form for purposes of resale in connection with
          their original issuance and if it retains Debt Securities in bearer
          form for its own account, it will only do so in accordance with the
          requirements of U.S. Treas. Reg. Section 1.163-5(c)(2)(i)(D)(6);

               (iv) if it transfers to any affiliate Debt Securities in bearer
          form for the purpose of offering or selling such Debt Securities
          during the restricted period, it will either (A) obtain from such
          affiliate for the benefit of the Company the representations and
          agreements contained in Sections 7(a)(i), 7(a)(ii) and 7(a)(iii) or
          (B) repeat and confirm the representations and agreements contained in
          Sections 7(a)(i), 7(a)(ii) and 7(a)(iii) on such affiliate's behalf
          and obtain from such affiliate the authority to so obligate it;

               (v) it will obtain for the benefit of the Company the
          representations and agreements contained in Sections 7(a)(i),
          7(a)(ii), 7(a)(iii) and 7(a)(iv) from any person other than its
          affiliate with whom it enters into a written contract, as defined in
          U.S. Treas. Reg. Section 1.163-5(c)(2)(i)(D)(4) for the offer or sale
          during the restricted period of Debt Securities in bearer form; and

               (vi) it will comply with or observe any other restrictions or
          limitations set forth in the Prospectus on persons to whom, or the
          jurisdictions in which, or the manner in which, the Debt Securities
          may be offered, sold, resold or delivered.

     All other terms used in the preceding paragraph have the meaning given to
     them by the U.S. Internal Revenue Code (the "Code") and regulations
     thereunder, including the D Rules. The restricted period is defined at U.S.
     Treas. Reg. Section 1.163-5(c)(2)(i)(D)(7).

     8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold
harmless each Underwriter and each person, if any, who controls any Underwriter
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act from and against any and all losses, claims, damages and
liabilities (including, without limitation, any legal or other expenses
reasonably incurred in connection with defending or investigating any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or any amendment thereof,
any preliminary prospectus or the Prospectus (as amended or supplemented if the
Company shall have furnished any amendments or supplements thereto), or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages or liabilities are caused by any
such untrue statement or omission or alleged untrue statement or omission based
upon information relating to any Underwriter furnished to the Company in writing
by such Underwriter through the Manager expressly for use therein.

     (b) Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to such Underwriter,
but only with reference to information relating to such Underwriter furnished to
the Company in writing by such Underwriter through the Manager expressly for use
in the Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto.

     (c) In case any proceeding (including any governmental investigation) shall
be instituted involving any person in respect of which indemnity may be sought
pursuant to either Section 8(a) or 8(b), such person (the "indemnified party")
shall promptly notify the person against whom such indemnity may be sought (the
"indemnifying party") in writing and the indemnifying party, upon request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred. Such firm shall be
designated in writing by the Manager, in the case of parties indemnified
pursuant to Section 8(a) above, and by the Company, in the case of parties
indemnified pursuant to Section 8(b) above. The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second and third
sentences of this paragraph, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and (ii) such indemnifying party
shall not have reimbursed the indemnified party in accordance with such request
prior to the date of such settlement. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

     (d) To the extent the indemnification provided for in Section 8(a) or 8(b)
is unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages or liabilities referred to therein, then each indemnifying party
under such paragraph, in lieu of indemnifying such indemnified party thereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other hand from the offering of the Offered
Securities or (ii) if the allocation provided by clause 8(d)(i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause 8(d)(i) above but also the
relative fault of the Company on the one hand and of the Underwriters on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other hand in connection with the offering of the
Offered Securities shall be deemed to be in the same respective proportions as
the net proceeds from the offering of such Offered Securities (before deducting
expenses) received by the Company and the total underwriting discounts and
commissions received by the Underwriters, in each case as set forth in the table
on the cover of the Prospectus Supplement, bear to the aggregate Public Offering
Price of the Offered Securities. The relative fault of the Company on the one
hand and the Underwriters on the other hand shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or by the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Underwriters' respective obligations to
contribute pursuant to this Section 8 are several in proportion to the
respective principal amounts of Offered Securities they have purchased
hereunder, and not joint.

     (e) The Company and the Underwriters agree that it would not be just or
equitable if contribution pursuant to this Section 8 were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in Section 8(d). The amount paid or payable
by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 8, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Offered
Securities underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages that such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 8 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

     (f) The indemnity and contribution provisions contained in this Section 8
and the representations, warranties and other statements of the Company
contained in this Agreement shall remain operative and in full force and effect
regardless of (i) any termination of this Agreement, (ii) any investigation made
by or on behalf of any Underwriter or any person controlling any Underwriter or
the Company, its officers or directors or any person controlling the Company and
(iii) acceptance of and payment for any of the Offered Securities.

     9. Termination. This Agreement shall be subject to termination by notice
given by the Manager to the Company, if (a) after the execution and delivery of
the Underwriting Agreement and prior to the Closing Date (i) trading generally
shall have been suspended or materially limited on or by, as the case may be,
any of the New York Stock Exchange, the American Stock Exchange, the National
Association of Securities Dealers, Inc., the Chicago Board of Options Exchange,
the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of
any securities of the Company shall have been suspended on any exchange or in
any over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in the judgment of the Manager, is material and adverse and (b) in the
case of any of the events specified in clauses 9(a)(i) through 9(a)(iv), such
event, singly or together with any other such event, makes it, in the judgment
of the Manager, impracticable to market the Offered Securities on the terms and
in the manner contemplated in the Prospectus.

     10. Defaulting Underwriters. If, on the Closing Date, any one or more of
the Underwriters shall fail or refuse to purchase Underwriters' Securities that
it has or they have agreed to purchase hereunder on such date, and the aggregate
amount of Underwriters' Securities which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase is not more than one-tenth
of the aggregate amount of the Underwriters' Securities to be purchased on such
date, the other Underwriters shall be obligated severally in the proportions
that the amount of Underwriters' Securities set forth opposite their respective
names in the Underwriting Agreement bears to the aggregate amount of
Underwriters' Securities set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as the Manager may specify, to
purchase the Underwriters' Securities which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date; provided
that in no event shall the amount of Underwriters' Securities that any
Underwriter has agreed to purchase pursuant to this Agreement be increased
pursuant to this Section 10 by an amount in excess of one-ninth of such amount
of Underwriters' Securities without the written consent of such Underwriter. If,
on the Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Underwriters' Securities and the aggregate amount of Underwriters'
Securities with respect to which such default occurs is more than one-tenth of
the aggregate amount of Underwriters' Securities to be purchased on such date,
and arrangements satisfactory to the Manager and the Company for the purchase of
such Underwriters' Securities are not made within 36 hours after such default,
this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter or the Company. In any such case either the Manager
or the Company shall have the right to postpone the Closing Date, but in no
event for longer than seven days, in order that the required changes, if any, in
the Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected. Any action taken under this paragraph shall not
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

     11. Counterparts. This Agreement may be signed in two or more counterparts,
each of which shall be an original, with the same effect as if the signatures
thereto and hereto were upon the same instrument.

     12. Applicable Law. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of New York.

     13. Headings. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

                           DELAYED DELIVERY CONTRACT





                                                                  ________, 199_





     Dear Ladies and Gentlemen:

     The undersigned hereby agrees to purchase from MSDW Structured Asset Corp.,
a Delaware corporation (the "Company"), and the Company agrees to sell to the
undersigned the Company's securities described in Schedule A annexed hereto (the
"Securities"), offered by the Company's Prospectus dated __________________,
19__ and Prospectus Supplement dated ________________, 19__, receipt of copies
of which are hereby acknowledged, at a purchase price stated in Schedule A and
on the further terms and conditions set forth in this Agreement. The undersigned
does not contemplate selling Securities prior to making payment therefor.

     The undersigned will purchase from the Company Securities in the principal
amount and numbers on the delivery dates set forth in Schedule A. Each such date
on which Securities are to be purchased hereunder is hereinafter referred to as
a "Delivery Date."

     Payment for the Securities which the undersigned has agreed to purchase on
each Delivery Date shall be made to the Company or its order by certified or
official bank check in New York Clearing House funds at the office of
______________________________, New York, N.Y., at 10:00 a.m. (New York City
time) on the Delivery Date, upon delivery to the undersigned of the Securities
to be purchased by the undersigned on the Delivery Date, in such denominations
and registered in such names as the undersigned may designate by written or
telegraphic communication addressed to the Company not less than five full
business days prior to the Delivery Date.

     The obligation of the undersigned to take delivery of and make payment for
the Securities on the Delivery Date shall be subject to the conditions that (1)
the purchase of Securities to be made by the undersigned shall not at the time
of delivery be prohibited under the laws of the jurisdiction to which the
undersigned is subject and (2) the Company shall have sold, and delivery shall
have taken place to the underwriters (the "Underwriters") named in the
Prospectus Supplement referred to above of, such part of the Securities as is to
be sold to them. Promptly after completion of sale and delivery to the
Underwriters, the Company will mail or deliver to the undersigned as its address
set forth below notice to such effect, accompanied by a copy of the opinion of
counsel for the Company delivered to the Underwriters in connection therewith.

     Failure to take delivery of and make payment for Securities by any
purchaser under any other Delayed Delivery Contract shall not relieve the
undersigned of its obligations under this agreement.

     This Agreement will inure to the benefit of and be binding upon the parties
hereto and their respective successors, but will not be assignable by either
party hereto without the written consent of the other.

     If this Agreement is acceptable to the Company, it is requested that the
Company sign the form of acceptance below and mail or deliver one of the
counterparts hereof to the undersigned at its address set forth below. This will
become a binding agreement, as of the date first above written, between the
Company and the undersigned when such counterpart is so mailed or delivered.

     This Agreement shall be governed by and construed in accordance with the
internal laws of the State of New York.



                                Very truly yours,

     Ladies and Gentlemen:

     We have acted as special counsel to MSDW Structured Asset Corp., a Delaware
corporation (the "Company"), in connection with the Company's offering pursuant
to a registration statement on Form S-3 (No. 33-_____) of the Structured Assets
Trust Unit Repackaging Units (the "Securities") to be issued under a Trust
Agreement dated as of February __, 1999 (the "Trust Agreement") between the
Company and Chase Bank of Texas, National Association, as trustee. Such
registration statement, as amended when it became effective, but excluding the
documents incorporated by reference therein, is herein called the "Registration
Statement," and the related prospectus, as supplemented by the prospectus
supplement dated ____________, and as first filed with the Securities and
Exchange Commission pursuant to Rule 424(b)(2) under the Securities Act, but
excluding the documents incorporated by reference therein, is herein called the
"Prospectus." This opinion letter is furnished pursuant to Section 5(c) of the
Underwriting Agreement dated February __, 1999 (the "Underwriting Agreement")
between the Company and the underwriter named in the Agreement (the
"Underwriter").

     In arriving at the opinions expressed below, we have reviewed the following
documents:

               (a) an executed copy of the Underwriting Agreement;

               (b) the Registration Statement and the documents incorporated by
          reference therein;

               (c) the Prospectus and the documents incorporated by reference
          therein;

               (d) a form of the Securities;

               (e) an executed copy of the Trust Agreement; and

               (f) the documents delivered to you by the Company at the closing
          pursuant to the Underwriting Agreement, including copies of the
          Company's Certificate of Incorporation and By-Laws certified by the
          Secretary of State of the State of Delaware and the corporate
          secretary of the Company, respectively.

     In addition, we have reviewed the originals or copies certified or
otherwise identified to our satisfaction of all such corporate records of the
Company and such other instruments and other certificates of public officials,
officers and representatives of the Company and such other persons, and we have
made such investigations of law, as we have deemed appropriate as a basis for
the opinions expressed below.

     In rendering the opinions expressed below, we have assumed the authenticity
of all documents submitted to us as originals and the conformity to the
originals of all documents submitted to us as copies. In addition, we have
assumed and have not verified the accuracy as to factual matters of each
document we have reviewed (including, without limitation, the accuracy of the
representations and warranties of the Company in the Underwriting Agreement).

     Based on the foregoing, and subject to the further assumptions and
qualifications set forth below, it is our opinion that:

     [1. The Company is validly existing as a corporation in good standing under
the laws of its jurisdiction of incorporation.]

     [2. The Company has corporate power to own its properties and conduct its
business as described in the Prospectus, and the Company has corporate power to
issue the Securities, to enter into the Underwriting Agreement and the Trust
Agreement and to perform its obligations thereunder.]

     3. The statements set forth under the headings "Description of Trust
Agreements" and "Description of Units" in the Prospectus, insofar as such
statements purport to summarize certain provisions of the Securities, and Trust
Agreement and the Certificate of Incorporation of the Company, provide a fair
summary of such provisions.

     4. The execution and delivery of the Underwriting Agreement have been duly
authorized by all necessary corporate action of the Company, and the
Underwriting Agreement has been duly executed and delivered by the Company.

     5. The sale of the Securities to the Underwriter pursuant to the
Underwriting Agreement, and the performance by the Company of its obligations in
the Underwriting Agreement and the Trust Agreement (a) do not require any
consent, approval, authorization, registration or qualification of or with any
governmental authority of the United States or the State of New York, except
such as have been obtained or effected under the Securities Act (but we express
no opinion as to any consent, approval, authorization, registration or
qualification that may be required under state securities or Blue Sky laws), and
(b) do not result in a breach or violation of any of the terms and provisions
of, or constitute a default under the Certificate of Incorporation or By-Laws of
the Company.

     [Insofar as the foregoing opinions relate to the valid existence and good
standing of the Company, they are based solely on a certificate of good standing
received from the Secretary of State of the State of Delaware and on a
telephonic confirmation from such Secretary of State.] Insofar as the foregoing
opinions relate to the validity, binding effect or enforceability of any
agreement or obligation of the Company, (a) we have assumed that each other
party to such agreement or obligation has satisfied those legal requirements
that are applicable to it to the extent necessary to make such agreement or
obligation enforceable against it, and (b) such opinions are subject to
applicable bankruptcy, insolvency and similar laws affecting creditors' rights
generally and to general principles of equity.

     The foregoing opinions are limited to the federal law of the United States
of America, and the law of the State of New York and the General Corporation Law
of the State of Delaware.

     We are furnishing this opinion letter to you, the Underwriter, solely for
your benefit in connection with the offering of the Securities. This opinion
letter is not to be used, circulated, quoted or otherwise referred to for any
other purpose, except that this opinion letter may be relied upon by (i) the
Trustee in its capacity as such and (ii) _______ in connection with their rating
of the Securities.

                                    Very truly yours,

                                    CLEARY, GOTTLIEB, STEEN & HAMILTON
