     RE:  10% Senior Subordinated Notes due 2013

Ladies and Gentlemen:

     We have acted as special California counsel to Ardent Health Services LLC,
a Delaware limited liability company (the "PARENT"), and rendered legal opinions
set forth herein, relating to that certain Indenture dated as of August 19, 2003
(the "INDENTURE") among Ardent Health Services, Inc., a Delaware corporation
(the "ISSUER"), the Parent, U.S. Bank Trust National Association, N.A., as
trustee, and each of the guarantors identified therein, including without
limitation, BHC Cedar Vista Hospital, Inc., a California corporation (the
"CALIFORNIA GUARANTOR").

     We refer to the Registration Statement on Form S-1 (File No. 333-110117)
(the "REGISTRATION STATEMENT") filed by Parent, Issuer, and the other
subsidiaries of the Parent named therein as guarantors (collectively, the
"SUBSIDIARY GUARANTORS") with the Securities and Exchange Commission under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), relating to the
registration of up to $225,000,000 principal amount of the Issuer's 10% Senior
Subordinated Notes due to 2013 (the "EXCHANGE NOTES"), to be issued in an
exchange offer for $225,000,000 principal amount of the Issuer's outstanding 10%
Senior Subordinated Notes due 2013 (the "ORIGINAL NOTES"). The Original Notes
are, and the Exchange Notes will be, guaranteed by the Parent and the Subsidiary
Guarantors, including the California Guarantor. Original Notes that are accepted
for exchange for Exchange Notes will be cancelled and retired.

     We are advised as follows: (1) the Original Notes were and the Exchange
Notes will be issued pursuant to the Indenture, (2) the Original Notes were
issued and sold on August 19, 2003 to Banc of America Securities LLC, UBS
Securities LLC, Banc One Capital Markets, Inc. and Merrill Lynch, Pierce, Fenner
& Smith Incorporated, the initial purchasers thereof (the "INITIAL PURCHASERS"),
without registration under the Securities Act, and (3) the Original Notes were
offered and sold by the Initial Purchasers to qualified institutional buyers in
reliance on Rule 144A under the Securities Act and in transactions outside the
United States in reliance on Regulation S under the Securities Act.

     In rendering the opinions expressed below, we have examined and relied
upon (i) copies of the Registration Statement, the Indenture and the Form of
Notation of Guarantee (the

"NOTATION OF GUARANTEE") under the Indenture, (ii) such questions of law as we
have deemed necessary or appropriate for the purposes of this Opinion, (iii)
such records of the California Guarantor, including, without limitation,
certificates of officers of California Guarantor, and (iv) such other documents
as we have deemed necessary as a basis for the opinions expressed below. The
Indenture and the Notation of Guarantee are hereinafter referred to together as
the "DOCUMENTS".

         In our examination, we have assumed, with your permission and without
independent investigation: (i) the genuineness of all signatures; (ii) the
legal capacity of all natural persons who signed one or more of the Documents;
(iii) the authenticity of all documents submitted to us as originals, the
conformity to originals of all documents submitted to us as copies and the
authenticity of the originals of such copies; (iv) the truth and accuracy of
each of the representations and warranties in the Indenture as to factual
matters; and (v) the absence of evidence extrinsic to the provisions of the
written agreements between the parties that the parties intended a meaning
contrary to that expressed by those provisions.

         With respect to our opinion as to good standing set forth in paragraph
1 below, we have relied solely on good standing certificates of public
officials in California.

         Based upon and subject to the foregoing and subject also to the
comments, assumptions, qualifications, limitations and exceptions set forth
below, we are of the opinion that:

         1.    The California Guarantor is duly incorporated and is validly
existing in good standing under the laws of the State of California.

         2.    The California Guarantor has corporate power and authority to
enter into and perform its obligations under the Indenture and the Notation of
Guarantee.

         3.    The Indenture has been duly authorized, executed and delivered
by the California Guarantor.

         4.    The Notation of Guarantee has been duly authorized by the
California Guarantor.

         We are qualified to practice law in the State of California and we
express no opinion on the laws of any jurisdiction other than the federal laws
of the United States and the laws of the State of California. No opinion is
expressed as to the application of any anti-fraud laws, federal or state
securities laws, or tax laws.

         We hereby consent to the filing of this opinion letter as an Exhibit to
the Registration Statement and to all references to our firm included in or made
a part of the Registration Statement. In giving such consent, we do not thereby
admit that we are within the category of persons whose consent is required by
Section 7 of the Securities Act or the related Rules promulgated by the
Securities and Exchange Commission.
