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

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.

Contracts with institutional investors, the aggregate amount of

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.


                               5



Delivery on the Closing Date of any Units that are (i) Units in
bearer form shall be effected by delivery of a single temporary

("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.


                               6



                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

      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

           States person and (B) it has not delivered and will
           not deliver within the United States or its
           possessions definitive Debt Securities in bearer form
           that are sold during the restricted period;

                     (ii) it has, and throughout the restricted
           period will have, in effect procedures reasonably
           designed to ensure that its employees or agents who
           are directly engaged in selling Debt Securities in
           bearer form are aware that such Debt Securities may
           not be offered or sold 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


                               9



                       (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


                               10



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.


                               11



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


                               12



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.


                               13



           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.

                                               ________, 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.


                               20



           Failure to take delivery of and make payment for
Securities by any purchaser under any other Delayed Delivery

                   OPINION OF COUNSEL FOR ISSUER


Morgan Stanley & Co. Incorporated
1585 Broadway
New York, New York  10036

MSDW Structured Asset Corp.
1585 Broadway
New York, New York  10036

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 September __, 1998 (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
September __, 1998





(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).


                               2



           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


                               3



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.


                               4
