13. Definitions. The initially capitalized terms Optionee, Initial Vesting Date and Grant Date shall have the meanings set forth on the first page of this Agreement; initially capitalized terms not otherwise defined herein shall have the meaning provided in the Plan and the Stockholders Agreement, and, as used herein, the following terms shall have the meanings set forth below:

“Actual Internal EBITDA” means, with respect to a calendar year, the Company’s actual earnings before interest, taxes, depreciation and amortization for such year, determined based on the Company’s audited financials.

Actual Internal EBITDA shall not be reduced by costs of the acquisition of the former CRC Health Group, Inc. by the Company, management and transaction fees payable to the Investors or their Affiliates, or non-cash equity incentive expenses. Actual Internal EBITDA shall be calculated without giving effect to purchase accounting for the acquisition of the former CRC Health Group, Inc. by the Company. For the avoidance of doubt, year 2007 shall include Actual Internal EBITDA accrued during all of calendar year 2007 attributable to all businesses owned by the Company and in operation as of January 1, 2007.

“Base Case” means, with respect to a specified calendar year within the Performance Period, the Actual Internal EBITDA target for the Company for such calendar year, which target shall be adjusted from time to time in good faith by the Compensation Committee to reflect the consequences of acquisitions, dispositions and start-ups of any new facilities and changes in GAAP promulgated by FASB or the SEC. Such adjustment by the Compensation Committee shall be made for the purpose of providing a consistent basis from year to year for computing the relationship of Actual Internal EBITDA to the Base Case in order to prevent the dilution or enlargement of the Optionee’s rights under this Agreement. Notwithstanding the foregoing, no adjustment to the Company’s Actual Internal EBITDA targets shall be made in respect of outpatient methadone based treatment start-ups (other than pain management start-ups for which an adjustment would be made). The initial Actual Internal EBITDA targets for the Company are set forth below:

Base Case		2007			2008			2009			2010			2011
Actual Internal EBITDA (in millions)		$	71.4		$	119.7		$	143.8		$	167.5		$	191.2
