Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On October 15, 2012, National Mentor Holdings, Inc. (the “Company”) entered into an Amendment Agreement (the “Amendment Agreement”), to amend and restate the credit agreement, dated as of February 9, 2011 (the “Original Credit Agreement”), among the Company, NMH Holdings, LLC, the subsidiary guarantors party thereto, UBS AG, Stamford Branch, as administrative agent and issuing lender, UBS Loan Finance LLC, as swingline lender and the lenders from time to time party thereto.

The Amendment Agreement amended and restated the Original Credit Agreement (as amended, the “Amended and Restated Credit Agreement”) and converted the existing term loan facility under the Original Credit Agreement into a tranche B-1 term loan facility in aggregate principal amount of $522.1 million (the “Tranche B-1 Term Loan”). The proceeds of the Tranche B-1 Term Loan were used to prepay the existing term loan facility. The Amendment Agreement also replaced the Company’s existing $75 million revolving credit facility and the borrowings thereunder with a new $75 million revolving credit facility (the “Amended Revolving Credit Facility”). Fees and expenses incurred in connection with the Amendment Agreement and paid at closing were approximately $1.7 million.

The interest rates under the Amended and Restated Credit Agreement were unchanged from the Original Credit Agreement, except that the LIBOR floor applicable to borrowings under the Amended and Restated Credit Agreement was reduced by 0.50%. As a result, borrowings under the Amended and Restated Credit Agreement bear interest as follows: (1) in the case of base rate loans, at a rate equal to the greater of (a) the prime rate of UBS AG, Stamford Branch, (b) the federal funds rate plus 1/2 of 1% and (c) the Eurodollar rate for an interest period of one-month beginning on such day plus 100 basis points (subject to a LIBOR floor of 2.25% per annum), plus 4.25%, and (2) in the case of Eurodollar loans, at the Eurodollar rate (subject to a LIBOR floor of 1.25% per annum), plus 5.25%.

In addition, if, prior to October 15, 2013, the Company prepays or reprices any portion of the Tranche B-1 Term Loan, the Company will be required to pay a prepayment premium of 1% of the loans being prepaid or repriced.

The foregoing description of the Amendment Agreement is a summary and does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment Agreement which is filed as Exhibit 10.1 to this Form 8-K and is incorporated herein by reference.
