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.

(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. (e) During the period beginning on the date of the Underwriting Agreement and continuing to and including the Closing Date, not to offer, sell, contract to sell or otherwise dispose of any debt securities of the 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 or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company's counsel and the Company's accountants in connection with the registration and delivery of the Offered Securities under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Prospectus and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Offered Securities to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or legal investment memorandum in connection with the offer and sale of the Offered Securities under state law and all expenses in connection with the qualification of the Offered Securities for offer and sale under state law as provided in Section 6(d) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or legal investment memorandum, (iv) the fees and disbursements of the Company's counsel and accountants and of the Trustee and its counsel, (v) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Offered Securities by the National Association of Securities Dealers, Inc., (vi) any fees charged by the rating agencies for the rating of the Offered Securities, [(vii) all fees and expenses in connection with the preparation and filing of the registration statement on Form 8-A relating to the Securities and all costs and expenses incident to listing the Offered Securities on [the NYSE/AMEX/the NASDAQ National Market] [and other national securities exchanges and foreign stock exchanges]], (viii) the costs and expenses of the Company relating to investor presentations on any "road show" undertaken in connection with the marketing of the offering of the Offered Securities, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and the cost of any aircraft chartered in connection with the road show, (ix) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section [and (x) all document production charges and expenses of counsel to the Underwriters incurred in connection with the preparation of the Indenture].

Covenants of the Underwriters. Each of the several Underwriters represents and agrees with the Company that: (i) except to the extent permitted under U.S. Treas. Reg. Section 1.163-5(c)(2)(i)(D) (the "D Rules"), (A) it has not offered or sold, and during the restricted period will not offer or sell, Debt Securities in bearer form (including any Debt Security in global form that is exchangeable for Debt Securities in bearer form) to a person who is within the United States or its possessions or to a United 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.

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.

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 April __, 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.
