The Registration Statement relates to the registration under the Act of debt securities (the "Debt Securities") to be issued by the Company in an underwritten offering. The Debt Securities are to be sold pursuant to an underwriting agreement to be entered into among the Company and the underwriters named therein (the "Underwriting Agreement"). The Debt Securities will be issued pursuant to indentures (the "Indentures"), each between the Company and The Bank of New York, as Trustee. The terms of the Debt Securities include those stated in the Indentures and those made part of the Indentures by reference to the Trust Indenture Act of 1939, as amended. [TENET ADDRESS] Tenet Healthcare Corporation Page 2 This opinion is delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act. In connection with this opinion, I have examined and am familiar with originals or copies, certified or otherwise identified to my satisfaction, of such records of the Company and all such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others and such other documents, certificates and records as I have deemed necessary or appropriate as a basis for the opinions set forth herein, including, without limitation, (i) the Registration Statement (together with the form of preliminary prospectus forming a part thereof), (ii) the Restated Articles of Incorporation and Restated By-laws of the Company, as amended to date, (iii) copies of certain resolutions adopted by the Board of Directors of the Company relating to the filing of the Registration Statement and any amendments or supplements thereto, the proposed issuance of the Debt Securities and related matters, (iv) the form of Underwriting Agreement and (v) forms of the Indentures. In my examination, I have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as certified, conformed or photostatic copies and the authenticity of the originals of such copies. As to any facts material to the opinions expressed herein which I have not independently established or verified, I have relied upon statements and representations of officers and other representatives of the Company and others. I am a member of the California Bar and for purposes of this opinion do not express any opinion as to the laws of any jurisdiction other than California and the General Corporation Law of the State of Nevada. Based on and subject to the foregoing, I am of the opinion that the Debt Securities will be, when issued and sold in accordance with the Registration Statement and the respective Indenture, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except that the enforcement of such obligations may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws affecting the enforcement of creditors' rights generally, and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).
