Item 1.01 Entry into a Material Definitive Agreement.

Amended and Restated Credit Agreement

Overview

On February 28, 2014 (the “Closing Date”), CRC Health Corporation (the “Company”), a wholly owned subsidiary of CRC Health Group, Inc., entered into an amendment agreement (the “Amended Credit Agreement”) to amend and restate the Company’s Credit Agreement, dated as of February 6, 2006, as amended and restated as of November 17, 2006, as further amended and restated as of January 20, 2011, and as further amended and restated as of March 7, 2012 (the “Existing Credit Agreement”), among the Company, CRC Health Group, Inc., Citibank, N.A. as administrative agent (in such capacity, the “Administrative Agent”), collateral agent, swing line lender and L/C issuer, the other lenders party thereto (collectively, the “Lenders”), and Citigroup Global Markets Inc., as lead arranger.

Pursuant to the Amended Credit Agreement, the Company obtained incremental term loans in the aggregate principal amount of $50.0 million (the “Term B-4 Loans”) the proceeds of which, together with other funds available to the Company, were used to pay the consideration for the acquisition (the “Habit Acquisition”) of all of the outstanding equity interests of Habit Holdings, Inc. (“Habit”), to refinance certain existing indebtedness of Habit and its subsidiaries (including accrued and unpaid interest and applicable premiums) and to pay fees and expenses related to the Habit Acquisition. All term loans under the Company’s senior secured credit facility will mature on November 16, 2015 (the “Maturity Date”). The Amended Credit Agreement continues to provide an aggregate amount of $63.0 million of revolving commitments (the “Revolving Credit Commitments”), which will terminate on August 16, 2015.

Interest Rates and Fees

The interest rates with respect to the Term B-4 Loans under the Amended Credit Agreement are based on: (i) for LIBOR loans for any interest period, a rate per annum equal to the LIBOR rate as determined by the Administrative Agent, plus an applicable margin of 4.50%, and (ii) for base rate loans, a rate per annum equal to the greater of (x) the prime rate of the Administrative Agent and (y) the federal funds rate plus one-half of 1.00%, plus an applicable margin of 3.50%. The interest rates for LIBOR loans and base rate loans with respect to the Revolving Credit Commitments and the existing term loans that were not refinanced pursuant to the Amended Credit Agreement (the “Term B-2 Loans” and the “Term B-3 Loans”), as set forth in the Existing Credit Agreement, were not modified by the Amended Credit Agreement.

Under the Amended Credit Agreement, the Company was required to pay to the Administrative Agent for the account of each lender of Term B-4 Loans (each, a “Term B-4 Lender”) as a closing fee in respect of the Term B-4 Loans, an amount equal to 0.75% of the stated principal amount of each such lender’s Term B-4 Loans.

The Amended Credit Agreement did not modify any other provisions in the Existing Credit Agreement with respect to administrative and other fees payable thereunder.

Prepayments

The Term B-4 Loans are subject to a 1.00% prepayment premium to the extent such Term B-4 Loans are refinanced or the terms thereof are amended for the purpose of reducing the applicable yield with respect thereto, in each case prior to August 28, 2014. Otherwise, the provisions relating to prepayments and commitment reductions under the Amended Credit Agreement are substantially similar to those under the Existing Credit Agreement.

Amortization of Term Loans

The Amended Credit Agreement requires scheduled quarterly payments in respect of (i) the Term B-2 Loans equal to (x) the percentage of all Term B-2 Loans and Term B-3 Loans outstanding on March 7, 2012 constituting Term B-2 Loans multiplied by (y) 0.25% of the aggregate amount of all term loans outstanding on November 17, 2006 (the amount in this clause (y), the “Quarterly Amortization Amount”), (ii) the Term B-3 Loans equal to (x) the percentage of all Term B-2 Loans and Term B-3 Loans outstanding on March 7, 2012 constituting Term B-3 Loans multiplied by (y) the Quarterly Amortization Amount, which payments in each case are subject to certain reductions, with the balance paid in the final quarterly installment, and (iii) beginning on the last Business Day of December, 2014, the Term B-4 Loans equal to 0.25% of the Term B-4 Loans outstanding on the Closing Date.
