This Option and any securities issued upon exercise of this Option are subject to restrictions on voting and transfer and requirements of sale and other provisions as set forth in the Stockholders Agreement among CRC Health Group, Inc. and certain investors, dated as of February 6, 2006, as amended from time to time (the “Stockholders Agreement”). This Option and any securities issued upon exercise of this Option constitute Management Shares as defined therein.

CRC HEALTH GROUP, INC.

STOCK OPTION

CERTIFICATE

This stock option (the “Agreement”) is granted by CRC Health Group, Inc. (f/k/a CRCA Holdings, Inc.), a Delaware corporation (the “Company”), to the Optionee, pursuant to the Company’s 2006 Executive Incentive Plan, as amended from time to time (the “Plan”). For the purpose of this Agreement, the “Grant Date” shall mean February 6, 2006.

1. Grant of Option. This certificate evidences the grant by the Company on the Grant Date to the Optionee of an option to purchase (the “Option”), in whole or in part, on the terms provided herein and in the Plan, [            ] Units at $[            ] per Unit.

Each “Unit” consists of 9 shares of Class A Common Stock of the Company, par value $.001 per share, and 1 share of Class L Common Stock of the Company, par value $.001 per share, subject to adjustment as provided in the Plan. The Option evidenced by this certificate is not intended to qualify as an incentive stock option under Section 422 of the Internal Revenue Code (the “Code”). This Option is granted in substitution of an option (which option is hereby deemed cancelled) held by the Optionee in CRC Health Corporation (f/k/a CRC Health Group, Inc.) (“Rollover Option”). Except as permitted in Section 409A Rollover Law and expressly provided in this Agreement, the terms of the Rollover Option are deemed incorporated into this Option; it being understood, that the exercise price and the number of shares may be adjusted as permitted under Section 409A Law. The Option shall be subject to the terms of the plan that previously governed the Rollover Option immediately prior to the date hereof, and to the terms of any other agreement previously governing the Rollover Option for which this Option is substituted to the extent required by Section 409A Rollover Law, and will also be governed by the Plan, as applicable, and the Stockholders Agreement, in each case to the extent consistent with Section 409A Rollover Law.

2. Vesting. The Option is fully vested.

3. Exercise of Option. Each election to exercise this Option shall be subject to the terms and conditions of the Plan and shall be in writing, signed by the Optionee or by his or her executor or administrator or by the person or persons to whom this Option is transferred by will or the applicable laws of descent and distribution (the “Legal Representative”),

-1-

and made pursuant to and in accordance with the terms and conditions set forth in the Plan. The latest date on which this Option may be exercised (the “Final Exercise Date”) is the latest date upon which the Rollover Option was exercisable, subject to earlier termination in accordance with the terms and provisions of the Plan and this Agreement.

4. Representations and Warranties of Optionee.

Optionee represents and warrants that:

(a) Authorization. Optionee has full legal capacity, power, and authority to execute and deliver this Agreement and to perform Optionee’s obligations hereunder. This Agreement has been duly executed and delivered by Optionee and is the legal, valid, and binding obligation of Optionee enforceable against Optionee in accordance with the terms hereof.

(b) No Conflicts. The execution, delivery, and performance by Optionee of this Agreement and the consummation by Optionee of the transactions contemplated hereby will not, with or without the giving of notice or lapse of time, or both (i) violate any provision of law, statute, rule or regulation to which Optionee is subject, (ii) violate any order, judgment or decree applicable to Optionee, or (iii) conflict with, or result in a breach of default under, any term or condition of any agreement or other instrument to which Optionee is a party or by which Optionee is bound.

Optionee has had an opportunity to obtain the advice of counsel (other than counsel to the Company or its Affiliates) prior to executing this Agreement, and fully understands all provisions of the Plan and this Agreement.

(e) Investment Intent. The Optionee is acquiring the Stock solely for the Optionee’s own account for investment and not with a view to or for sale in connection with any distribution of the Stock or any portion thereof and not with any present intention of selling, offering to sell or otherwise disposing of or distributing the Stock or any portion thereof in any transaction other than a transaction exempt from registration under the Securities Act. The Optionee further represents that the entire legal and beneficial interest of the Stock is being acquired, and will be held, for the account of the Optionee only and neither in whole nor in part for any other person.

(f) Absence of Solicitation. The Optionee was not presented with or solicited by any form of general solicitation or general advertising, including, but not limited to, any advertisement, article, notice, or other communication published in any

(j) Reliance by the Company. The Optionee understands that the Option and any shares acquired upon exercise of the Option have not been qualified under the Corporate Securities Law of 1968, as amended, of the State of California by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Optionee’s representations as expressed herein. The Optionee understands that the Company is relying on the Optionee’s representations and warrants that the Company is entitled to rely on such representations and that such reliance is reasonable.
