EXECUTION COPY

ROLLOVER AGREEMENT

ROLLOVER AGREEMENT, dated as of July 21, 2006 (this “Agreement”), by and among COLLECT HOLDINGS, INC., a Delaware corporation (“Parent”), Michael Barrist and the several other individuals and entities named on Part A of Schedule I hereto (each a “Rollover Investor” and collectively, the “Rollover Investors”).

WITNESSETH:

WHEREAS, on the date hereof, Parent, Collect Acquisition Corp., a Pennsylvania corporation and a wholly owned subsidiary of Parent (“Acquisition”), and NCO Group, Inc., a Pennsylvania corporation (“Target”), are entering into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which, upon the terms and subject to the conditions set forth therein, Acquisition will merge with and into Target (the “Merger”) with Target continuing as the surviving corporation;

WHEREAS, on or prior to the closing of the Merger (the “Closing”), the Certificate of Incorporation of Parent will be amended and restated in substantially the form of Exhibit A hereto (the “Restated Parent Charter”), and pursuant to the Restated Parent Charter, the authorized capital stock of Parent will consist of 6,500,000 shares of Preferred Stock, par value $.01 per share, including 6,000,000 shares of Series A 14% PIK Preferred Stock (“Parent Series A Preferred Stock”), 300,000 shares of Class L Common Stock, par value $.01 per share (“Parent Class L Common Stock”), and 2,750,000 shares of Class A Common Stock, par value $.01 per share (“Parent Class A Common Stock”);

WHEREAS, each Rollover Investor is the beneficial owner of at least the number of shares of Common Stock, no par value, of Target (“Target Common Stock”), set forth opposite such Rollover Investor’s name on Part A of Schedule I hereto under the heading “Rollover Shares” (the number of such shares set forth opposite such Rollover Investor’s name being the “Rollover Shares”); and

WHEREAS, each of the Rollover Investors, acting severally and not jointly, is willing to contribute such Rollover Investor’s Rollover Shares to Parent in exchange for newly issued shares of Parent Class L Common Stock and Parent Class A Common Stock, upon the terms and subject to the conditions set forth herein.

NOW, THEREFORE, the parties hereto agree as follows:

ARTICLE I.

AGREEMENTS

SECTION 1.01. Rollover. At the Closing, each Rollover Investor will purchase or cause to be purchased from Parent (i) at a purchase price of $247.50 per share, that number of shares of newly issued Parent Class L Common Stock as is set forth opposite such Rollover Investor’s name under the heading “Shares of Parent Class L Common Stock” on Part A of Schedule I hereto, and (ii) at a purchase price of $10 per share, that number of shares of newly issued Parent Class A Common Stock as is set forth opposite such Rollover Investor’s name under the heading “Shares of Parent Class A Common Stock” on Part A of Schedule I hereto (such

1

shares of Parent Class L Common Stock and Parent Class A Common Stock, collectively the “Shares”), by delivering and contributing to Parent, as payment in full for the Shares, such Rollover Investor’s Rollover Shares (the “Rollover”), valuing each share of Target Common Stock so contributed to Parent at $27.50 per share (i.e., an amount equal to the Merger Consideration). The foregoing allocation of Parent Class L Common Stock and Parent Class A Common Stock for each Rollover Investor’s Rollover Shares, is based on the assumption that One Equity Partners II, L.P., a Cayman Islands limited partnership (“OEP II”), OEP II Co Investors, L.P., a Cayman Islands limited partnership (“OEP II Co-Invest”), and OEP II Partners Co-Invest, L.P., a Cayman Islands limited partnership (“OEP II Partners Co-Invest,” and together with OEP II and OEP Co-Invest, “OEP”), will purchase (i) shares in units composed of either (i) four (4) newly issued shares of Parent Series A Preferred Stock at a purchase price of $237.50 per share and five (5) newly issued shares of Parent Class A Common Stock at a purchase price of $10 per share or (ii) four (4) newly issued shares Parent Class L Common Stock at a purchase price of $247.50 per share and one (1) newly issued share of Parent Class A Common Stock at a purchase price of $10 per share (the “OEP Subscription”). To the extent that, prior to the Rollover Closing (as defined below), the OEP Subscription is composed of units different than those described above (including with respect to the price, allocation, class or number of shares), the parties shall in good faith agree upon an equitable adjustment for each Rollover allocation to maintain the intended position of proportional economic equivalence (disregarding the different tax attributes of the Class L Common Stock and the Preferred Class A Stock).

SECTION 1.02. Closing. Upon the terms and subject to the conditions of this Agreement, the closing of the Rollover contemplated by Section 1.01 (the “Rollover Closing”) shall take place immediately prior to the closing of the Merger at the same location as the Merger closing and concurrent with the OEP Subscription.

SECTION 1.03. Stockholders Agreement and Registration Rights Agreement. Parent and each Rollover Investor agrees that, at the Rollover Closing, they shall enter into (a) a stockholders agreement on the terms set forth in Exhibit B hereto and such other customary terms that are not in conflict with such terms (the “Stockholders Agreement”); and (b) a registration rights agreement on the terms set forth in Exhibit C hereto and such other customary terms that are not in conflict with such terms (the “Registration Rights Agreement”).

SECTION 1.04. Management Agreements and Acknowledgements.

(a) Parent and Michael Barrist agree that, at the Rollover Closing, they shall enter into an employment agreement on the terms set forth in Exhibit D hereto and such other customary terms that are not in conflict with such terms (the “Barrist Employment Agreement”).

(b) Parent agrees to use commercially reasonable efforts to enter into employment agreements with the individuals listed on, and on the terms set forth on, Exhibit E and such other customary terms that are not in conflict with such terms (“Management Employment Agreements”); and

2

(c) Parent shall adopt a Restricted Stock Plan on the terms set forth on the terms set forth in Exhibit F hereto and such other customary terms that are not in conflict with such terms (the “Restricted Stock Plan”).

SECTION 1.05. Restrictions on Transfers. Each Rollover Investor agrees that, except as otherwise provided herein, without the prior written consent of Parent, it will not make any transfer, sale, assignment, pledge, hypothecation or other disposition (including by operation of law), whether directly or indirectly pursuant to the creation of a derivative security, the grant of an option or other right or the imposition of a restriction on disposition or voting (in each case, a “Transfer”), of any of its Rollover Shares, except in connection with bona fide estate, financial or tax planning purposes after providing 3 Business Days notice to Parent, provided that any transferee executes and delivers to Parent an instrument satisfactory to Parent agreeing that such transferee will be bound by this Agreement as if such transferee was a Rollover Investor.

SECTION 1.06. Voting. Each Rollover Investor agrees that he, she or it will vote or execute consents in respect of each share of Target Common Stock with respect to which he, she or it has voting power at the time of such shareholder meeting or request for consent, in favor of the Merger Agreement, the Merger and the other transactions contemplated by the Merger Agreement. Notwithstanding anything herein to the contrary, the Target shall have the right to enforce the obligations of each Rollover Investor set forth in this Section 1.06.

SECTION 1.07. Appraisal Rights. Each Rollover Investor hereby waives any and all appraisal, dissenters and similar rights that the Rollover Investor may have with respect of the Merger and the other transactions contemplated by the Merger Agreement.

SECTION 1.08. Rollover Investor Capacity. Parent acknowledges that each Rollover Investor does not make any agreement or understanding in such Rollover Investor’s capacity (if applicable) as a director or officer of the Target. Each Rollover Investor executes this Agreement solely in his, her or its capacity as a stockholder of the Target and nothing herein shall limit in affect any actions taken by the Rollover Investor in his, her or its capacity as an offer or director of the Target.

SECTION 1.09. Certain Tax Matters. Each party acknowledges that it is intended that the Rollover effected pursuant to Section 1.01 shall be treated as a tax-free transfer under the Internal Revenue Code of 1986, as amended, and agrees to treat the transaction for all federal, state and local income tax purposes accordingly.
