We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and the Guarantors and such agreements, certificates of public officials, certificates of officers or other representatives of the Company, the Guarantors and others, and such other documents, certificates and re cords as we have deemed necessary or appropriate as a basis for the opinions set forth herein. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, facsimile, conformed or photostatic copies and the authenticity of the originals of such latter documents. In making our examination of documents executed or to be executed, we have assumed that the parties thereto other than the Company and the Guarantors had or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and execution and delivery by such parties of such documents and the validity and binding effect of such documents on such parties. In addition, we have assumed with respect to the Guarantors listed on Schedule I, that (i) Biltmore Surgery Center, Inc. ("Biltmore") has been duly organized and is validly existing and in good standing under the laws of the State of Arizona and that it has complied in all respects with the laws of the State of Arizona governing its execution, delivery and performance of the Guarantee to which it is a party and the Indenture and (ii) IASIS Healthcare MSO Sub of Salt Lake City, LLC ("MSO Sub") has been duly organized and is validly existing and in good standing under the laws of the State of Utah and that it has complied in all respects with the laws of the State of Utah governing its execution, delivery and performance of the Guarantee to which it is a party and the Indenture. As to any facts material to the opinion expressed herein which have not been independently established or verified, we have relied upon the oral or written statements and representations of officers and other representatives of the Company, the Guarantors and others. 4 IASIS Healthcare Corporation April 11, 2000 Page 4 Our opinions set forth herein are limited to, the Delaware Revised Uniform Limited Partnership Act, the Delaware General Corporation Law and those laws of the States of New York and Delaware which are normally applicable to transactions of the type contemplated by the Exchange Offer and, to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws (all of the foregoing being referred to as "Opined on Law"). We do not express any opinion with respect to the law of any jurisdiction other than Opined on Law or as to the effect of any such non-opined law on the opinions herein stated. Members of this firm are admitted to the Bar in the States of New York and Delaware, and we do not express any opinion as to the laws of any other jurisdiction. Based upon and subject to the foregoing and the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that: 1. When (a) the Registration Statement becomes effective and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), and (b) the New Notes (in the form examined by us) have been duly executed and authenticated in accordance with the terms of the Indenture and have been delivered upon consummation of the Exchange Offer against receipt of Old Notes surrendered in exchange therefor in accordance with the terms of the Exchange Offer, the Registration Rights Agreement and the Indenture, the New Notes will constitute valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforce able against the Company in accordance with their terms, except that (i) the enforcement thereof may be limited by (A) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws now or hereafter in effect relating to creditors' rights generally and (B) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity) and 5 IASIS Healthcare Corporation April 11, 2000 Page 5 (ii) the waiver included in Section 4.06 of the Indenture may be unenforceable; and 2. When (a) the Registration Statement becomes effective under the Securities Act and the Indenture has been qualified under the Trust Indenture Act, and (b) the New Notes have been duly executed and authenticated in accordance with the terms of the Indenture and have been issued and delivered upon consummation of the Exchange Offer against receipt of Old Notes surrendered in exchange therefor in accordance with the terms of the Exchange Offer, the Registration Rights Agreement and the Indenture, and each of the Guarantees has been attached thereto in accordance with the Exchange Offer, each Guarantee will constitute the valid and binding obligation of the Guarantor(s) a party thereto, enforceable against each such Guarantor in accordance with its terms, except that (i) the enforcement thereof may be limited by (A) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws now or hereafter in effect relating to creditors' rights generally and (B) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity) and (ii) the waiver included in Section 4.06 of the Indenture may be unenforceable. We express no opinion as to whether the execution and delivery by the Company of the Indenture and the New Notes and the execution and the delivery by each Guarantor of the Indenture and the Guarantee to which it is a party, and the performance by the Company and each of the Guarantors of their respective obligations thereunder violate, conflict with or constitute a default under or will violate, conflict with or constitute a default under any agreement or instrument to which the Company or any Guarantor or its properties is subject. In rendering our opinion set forth in paragraph 2 above with respect to the enforceability of the Guarantees of Biltmore and MSO Sub against each of Biltmore and MSO Sub, we have assumed that the execution and delivery by each of 6 IASIS Healthcare Corporation April 11, 2000 Page 6 Biltmore and MSO Sub of the Indenture and the Guarantee to which each is a party and the performance by each of Biltmore and MSO Sub of its obligations thereunder do not and will not (i) violate the laws of the State of Arizona or the State of Utah, respectively, or (ii) violate, conflict with or constitute a breach or default under the Articles of Incorporation or the Bylaws of Biltmore or the Articles of Organization or the Operating Agreement of MSO Sub.
