Ladies and Gentlemen:

We have acted as special Ohio counsel to Generations BH, LLC (“GBH”), Ohio Hospital for Psychiatry, LLC (“OHP”), Shaker Clinic, LLC (“SC”) and Ten Lakes Center, LLC (“TLC”, and together with GBH, OHP and SC, being referred to herein collectively as the “Ohio Guarantors”, and each individually as an “Ohio Guarantor”), in connection with the proposed guarantee from each of the Ohio Guarantors, along with the other guarantors under the Indenture (as hereinafter defined), of $375,000,000 in aggregate principal amount of 5.625% Senior Notes due 2023 (the “Exchange Notes”) to be issued by Acadia Healthcare Company, Inc., a Delaware corporation (the “Company”), in connection with an exchange offer to be made pursuant to a Registration Statement on Form S-4 (such Registration Statement, as supplemented or amended, is hereinafter referred to as the “Registration Statement”), to be filed with the Securities and Exchange Commission (the “Commission”) on or about July 2, 2015, under the Securities Act of 1933, as amended (the “Securities Act”). The obligations of the Company under the Exchange Notes will be guaranteed by the Ohio Guarantors (the “Guarantees”), along with other guarantors. The Exchange Notes and the Guarantees are to be issued pursuant to the Indenture, dated as of February 11, 2015 (the “Indenture”), among the Company, the guarantors named therein and U.S. Bank National Association, as trustee. Capitalized terms not otherwise defined herein shall have the respective meaning assigned to such terms in Exhibit A attached hereto.

Except as described in this letter, we are not generally familiar with the Ohio Guarantors’ businesses, records, transactions, or activities. Our knowledge of their businesses, records, transactions, and activities is limited to the information that is set forth below and on Exhibit A and the Transaction Documents and the Authorization Documents (as hereinafter defined). We have examined copies, certified or otherwise identified to our satisfaction, of the documents listed in the attached Exhibit A, which is made a part hereof. For the purposes of this opinion, the documents listed as items 1 through 3 in Exhibit A are hereinafter referred to collectively as the “Transaction Documents” and the documents listed as items 4 through 9 in Exhibit A are hereinafter referred to collectively as the “Authorization Documents”.

In rendering our opinion, we also have examined such certificates of public officials, organizational documents and records and other certificates and instruments as we have deemed necessary for the purposes of the opinion herein expressed and, with your permission, have relied upon and assumed the accuracy of such certificates, documents, records and instruments. We have made such examination of the laws of the State of Ohio (the “State”) as we deemed relevant for purposes of this opinion, but we have not made a review of, and express no opinion concerning, the laws of any jurisdiction other than the laws of the State.

We have relied upon and assumed the truth and accuracy of the factual representations, certifications and warranties made in the Transaction Documents and the Authorization Documents, and have not made any independent investigation or verification of any factual matters stated or represented therein; provided, however, that such reliance and assumption would not be applicable to the extent we have actual knowledge that any such representation, certification or warranty made by any Ohio Guarantor is in any material way inaccurate or incorrect. Whenever our opinion or confirmation herein with respect to the existence or absence of facts is indicated to be based upon our knowledge or belief, it is intended to signify that, during the course of our representation of the Ohio Guarantors no information has come to the attention of the attorneys who participated in the representation which would give us actual knowledge of the existence or absence of such facts. Except to the extent expressly set forth herein, we have not undertaken any independent investigation to determine the existence or absence of such facts or circumstances or the assumed facts set forth herein, we accept no responsibility to make any such investigation, and no inference as to our knowledge of the existence or absence of such facts or circumstances or of our having made any independent review thereof should be drawn from our representation of the Ohio Guarantors. Our representation of the Ohio Guarantors is limited to the transactions contemplated by the Transaction Documents and other matters specifically referred to us by the Ohio Guarantors.

In rendering this opinion letter to you, we have assumed with your permission:

(a) Each document we have reviewed (including the Transaction Documents and the Authorization Documents) is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, no such document has been amended, altered, revoked or otherwise modified, and all signatures on each such document are genuine.

(b) The documents that have been or will be executed and delivered in consummation of the transactions contemplated by the Transaction Documents are or will be identical in all material and relevant respects with the copies of the documents we have examined and on which this opinion is based.

(c) Each party to the Transaction Documents (other than the Ohio Guarantors) (i) has been organized, is validly existing, and where applicable is in good standing under its jurisdiction of formation, (ii) has full power and authority to enter into, execute, deliver,

Based on the foregoing and upon such investigation as we have deemed necessary, and subject to the assumptions, qualifications, exceptions and limitations set forth herein, we are of the opinion that:

1. Each Ohio Guarantor is a limited liability company existing under the laws of, and is in full force and effect with, the State.

2. Each Ohio Guarantor has the limited liability company power and authority to enter into and to perform its obligations under the Indenture and the Guarantees.

3. Each Ohio Guarantor has duly authorized, executed and delivered the Indenture and has duly authorized the Guarantees.

4. The execution and delivery of the Indenture and the Guarantees by each Ohio Guarantor and the performance by each Ohio Guarantors of its obligations thereunder (a) do not and will not conflict with, contravene, violate or constitute a default under its Articles of Organization or Operating Agreement, or (b) neither is prohibited by, nor subjects any Ohio Guarantor to a fine, penalty or other similar sanction under, any statute or regulation directly applicable to the Indenture, the Guarantees or the transactions contemplated thereby.

5. No consent, approval, authorization or order of any State court or governmental authority was required in connection with the execution and delivery of the Indenture by each Ohio Guarantor or is required for the issuance by each Ohio Guarantor of the Guarantees.

Each of the opinions set forth above is limited by its terms and subject to the assumptions hereinabove stated and is further subject to the following qualifications, exceptions and limitations, none of which shall limit the generality of any other assumption, qualification, exception or limitation:

A. We express no opinion and make no statements concerning or with respect to any statutes, ordinances, administrative decisions, rules, and regulations of counties, towns, municipalities, and special political subdivisions.

B. Without limiting the generality of any other exception, limitation or qualification, (i) the opinions set forth herein are limited to, and no opinion is implied or may be inferred beyond, the matters expressly stated herein, and (ii) we express no opinion in this letter with respect to (a) federal or state (including the State) securities, tax, antitrust or unfair competition laws and regulations, (b) the application of any law, statute, rule or regulation relating to the environment, health or safety; (c) any law, statute, rule, or regulation that may apply to any

party as a result of its activities in the State that are not directly related to the transactions contemplated by the Transaction Documents; (d) federal or state (including the State) laws and regulations concerning filing and notice requirements (e.g., Hart-Scott-Rodino and Exon-Florio); (e) compliance with fiduciary duty requirements; (f) federal and state laws, regulations and policies concerning (i) national and local emergency, (ii) possible judicial deference to acts of sovereign states, and (iii) criminal and civil forfeiture laws; and (g) other federal and state statutes of general application to the extent they provide for criminal prosecution (e.g., mail fraud and wire fraud statutes).

Your attention is called to Ohio Revised Code Sections 2905.21(H)(1) and 2905.22 which prohibit as criminal usury the taking of interest at any rate in excess of 25% per annum, unless otherwise authorized by law; although Ohio Revised Code Section 1343.01(B)(1) may constitute such authorization, no opinion is expressed herein that the taking of interest in excess of 25% per annum would not be criminal usury under such sections.

D. The opinions set forth in paragraph 1 above relative to the existence under the law of, and full force and effect with, the State of each Guarantor are based only upon its Certificate of Full Force and Effect.

E. The effect of the Transaction Documents may be limited or otherwise affected if: (i) any Ohio Guarantor was or is rendered “insolvent”, as that term is defined under Section 548 of the United States Bankruptcy Code, at the time the Transaction Documents were executed or performed, or as a result of their execution or performance; (ii) any Ohio Guarantor will not directly or indirectly benefit from the extension of credit under the Transaction Documents; and (iii) legally adequate consideration has not been received by any Ohio Guarantor in exchange for the transfers made and obligations incurred in connection with the transactions contemplated by the Transaction Documents and the delivery of the Transaction Documents.

F. The opinions set forth herein relating to the Transaction Documents are limited to only the provisions actually contained in the Transaction Documents, and do not extend to any provisions incorporated into any of the Transaction Documents by reference to any other document(s).

G. As used herein, as to each Ohio Guarantor, the phrases “limited liability company power and authority” and “duly authorized” refer and are limited to (a) the Ohio Limited Liability Company Act [Ohio Revised Code Chapter 1705], (b) its Articles of Organization, (c) its Operating Agreement and (d) its Resolutions.

H. Applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and transfer and other similar laws, and judicially developed doctrines relevant to any of the foregoing laws, affecting creditors’ rights generally, and the discretion of the court before which any proceeding therefor may be brought.
