Item 2.01. Completion of Acquisition or Disposition of Assets.

Pursuant to an Agreement and Plan of Merger dated December 11, 2007 (the “Merger Agreement”), by and between NCO Group, Inc (“NCO”), NCO Acquisition Sub, Inc., a wholly-owned subsidiary of NCO (“Sub”) and Outsourcing Solutions Inc. (“OSI”), on February 29, 2008, the merger was completed and Sub merged with and into OSI with OSI being the surviving corporation and a direct, wholly-owned subsidiary of NCO (the “Acquisition”). OSI is a leading provider of business process outsourcing primarily accounts receivable management services. NCO acquired OSI for $325.0 million in cash, subject to certain post-closing adjustments (the “Merger Consideration”). Approximately $139.0 million of the Merger Consideration was funded from NCO’s Amended Credit Facility (as defined below) and $186.0 million was funded from NCO’s private placement of its Series A Preferred Stock, Class L Common Stock and Class A Common Stock. The terms of the Amendment (as defined below) to the Amended Credit Facility and the private placement are described below in Items 2.03 and 3.02, respectively, of this Form 8-K and incorporated by reference into this Item 2.01.

In connection with the Acquisition, NCO and OSI stockholders’ representative entered into an escrow agreement dated February 29, 2008. Of the Merger Consideration, $10.0 million is being held in escrow until June 30, 2009 to indemnify NCO for losses, liabilities, damages, claims, suits, settlements, costs and expenses arising from, among other things, breaches of representations and warranties made by the seller in the Merger Agreement and certain legal matters against OSI (“Escrow Amount”). Promptly after June 30, 2009, Escrow Amounts remaining in escrow with interest thereon will be distributed to former holders of OSI’s class A common stock, class A preferred stock and stock units. If prior to June 30, 2009 certain legal matters against OSI is not settled or a final non-appealable decision is not made, an amount not to exceed $2.0 million shall remain in escrow from the Escrow Amount until such matter is settled or a final non-appealable decision is made. An additional $10.0 million of the Merger Consideration is being held in escrow until the tangible net worth adjustment is determined in accordance with the Merger Agreement (“Net Tangible Amount Escrow”). If the tangible net worth is positive, the entire $10.0 million of the Net Tangible Amount Escrow with interest thereon will be distributed to the former holders of OSI’s class A common stock, class A preferred stock and stock units. If the tangible net worth is negative, an amount equal to the lesser of (i) the tangible net worth adjustment, together with any interest earned on that portion of the $10.0 million equal to the tangible net worth adjustment or (ii) the full amount of the $10.0 million of the Net Tangible Amount Escrow with interest thereon will be distributed to NCO. If the Net Tangible Amount Escrow is insufficient to cover the amount required to be paid, then the insufficiency will be paid out of the Escrow Amount.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to such document, a copy of which will be filed as an exhibit to NCO’s Annual Report on 10-K for the fiscal year ended December 31, 2007.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

NCO, NCO Financial Systems, Inc., certain Guarantors under the Credit Agreement (as defined below), Citizens Bank of Pennsylvania and RBS Securities Corporation d/b/a RBS Greenwich Capital, as lead arranger and bookrunner and the Lenders (as defined in the Credit Agreement defined below) entered into a First Amendment to Credit Agreement, dated as of February 8, 2008, which became effective on February 29, 2008 (the “Amendment”). The Amendment amends the Credit Facility, dated as of November 15, 2006, among Collect Acquisition Corp., the Initial Subsidiary Borrower (as defined therein), Collect Holdings, Inc. (n/k/a NCO), the Subsidiary Guarantors party thereto, the Lenders party thereto, the Issuing Banks (as defined therein), the Swing Line Bank (as defined therein), Morgan Stanley & Co. Incorporated, as collateral agent for the Secured Parties (as defined therein) and Morgan Stanley Funding, Inc., as administrative agent for the Lender Parties (as defined therein) (the “Credit Agreement,” and together with the Amendment, is referred to as the “Amended Credit Facility”). The Amendment, among other things, provides for an add-on term B commitment not to exceed $139.0 million, all of which was used to fund a portion of the Acquisition. Under the Amended Credit Facility, NCO is required to make quarterly repayments of $1.5 million on the term loan until the maturity date of May 15, 2013, at which time the remaining balance outstanding is due. NCO is also required to make annual prepayments, beginning in 2007, of 50 percent, 25 percent or zero percent of its excess annual cash flow, based on NCO’s leverage ratio. Borrowings

under the Amended Credit Facility are collateralized by substantially all of NCO’s assets. The Credit Facility contains certain financial and other covenants such as maintaining a maximum leverage ratio and a minimum interest coverage ratio, and includes restrictions on, among other things, acquisitions, the incurrence of additional debt, investments, disposition of assets, liens and dividends and other distributions. If an event of default, such as failure to comply with covenants or change of control, were to occur under the Amended Credit Facility, the lenders would be entitled to declare all amounts outstanding under it immediately due and payable and foreclose on the pledged assets. As of February 29, 2008, NCO had outstanding borrowings of $640.4 million under the Amended Credit Facility.
