                           AMENDMENT NO. 2 AND CONSENT
                TO SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

     This AMENDMENT NO. 2 AND CONSENT TO SEVENTH AMENDED AND RESTATED CREDIT
AGREEMENT (this "Amendment") is dated as of July 13, 2006, by and among NCO
GROUP, INC., a Pennsylvania corporation ("Borrower"), the LENDERS referred to in
the Credit Agreement (as hereinafter defined) and CITIZENS BANK OF PENNSYLVANIA,
a Pennsylvania state-chartered bank, for itself and as Administrative Agent for
the other Lenders (in such capacity, together with its successors and assigns in
such capacity, the "Administrative Agent"). Capitalized terms used and not
otherwise defined in this Amendment shall have the meanings ascribed in the
Credit Agreement,

                                   BACKGROUND

     WHEREAS, the parties hereto are party to a certain Seventh Amended and
Restated Credit Agreement dated as of June 21, 2005 (as amended, restated,
supplemented or modified from time to time, the "Credit Agreement");

     WHEREAS, the Borrower has requested that the Lenders modify the Credit
Agreement to allow the Borrower to enter into a certain Agreement and Plan of
Merger with one or more entities, controlled, directly or indirectly, by One
Equity Partners II, L.P., One Equity Partners LLC, their affiliates and/or
Michael Barrist, pursuant to which, among other things, but subject to, the
required level of shareholder approval and certain other conditions, one of such
entities would be merged with and into the Borrower with the result that the
existing shareholders (excluding certain shareholders described therein) of the
Borrower would receive cash instead of shares and the shares of the post-merger
Borrower would be issued to another of such entities;

     WHEREAS, the Borrower has told the Lenders that, if and when those
conditions are satisfied and the merger is consummated, the debt under the
Credit Agreement will be repaid in full; and

     WHEREAS, the Administrative Agent and Majority Lenders are willing to
modify the Credit Agreement on the terms and conditions hereinafter set forth;

     NOW, THEREFORE, in consideration of the mutual promises herein contained,
and other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto, intending to be legally bound hereby,
agree as follows:

     1. Amendments to Credit Agreement and Consent, From and after the date on
which each of the conditions set forth in Section 2 below has been satisfied,
all references to the Credit Agreement in the Loan Documents shall mean and
refer to the Credit Agreement as modified as follows:

<PAGE>

          (a) Section 6.9 of the Credit Agreement (Mergers, Acquisitions, Etc.)
shall be amended by adding the following at the end thereof.

          "Notwithstanding the foregoing, the Borrower may enter into the
          Permitted Merger Agreement so long as:

                    (1) the Permitted Merger Agreement is terminated (subject to
                    Section 7.2 thereof) or consummated in accordance with
                    clause (2) below no later than the earlier of (a) the date
                    specified in Section 7.1(c) of the Permitted Merger
                    Agreement once executed and delivered by the parties thereto
                    and as the same may be amended by the parties thereto or (b)
                    March 15, 2007, subject in the case of both (a) and (b) to
                    an extension of up to 30 days at the election of the
                    Administrative Agent; and

                    (2) at the time that the merger transactions contemplated
                    thereby are consummated, the Secured Obligations are paid in
                    full (or, with the consent of such Lenders, Issuer or Swap
                    Parties as shall have Secured Obligations that are not paid
                    in full, cash collateralized in an amount equal to 110% or
                    otherwise secured to the satisfaction of such Persons) and
                    the Commitment is terminated."

          (b) Section 6.14 (Limitation on Other Restrictions On Liens) is
amended by inserting the following phrase at the end thereof immediately prior
to the period: "and (c) the prohibitions on granting Liens set forth in the
Permitted Merger Agreement."

          (c) Section 10.1 (Certain Definitions) is amended by inserting the
following additional definition in its correct alphabetical order.

          "PERMITTED MERGER AGREEMENT" means that certain Agreement and Plan of
          Merger among the Borrower and one or more entities controlled,
          directly or indirectly, by One Equity Partners II, L.P., One Equity
          Partners LLC, their affiliates and/or Michael Barrist, in
          substantially the form of the draft dated June 27, 2006, with such
          changes thereto as the Administrative Agent may approve."

          (d) The Lenders consent to the waiver of the provisions of Section
6.15 (Limitations on Restrictions on Amendment of the Loan Document) to allow
the Borrower to agree to Section 4.1 of the Permitted Merger Agreement but such
consent to waiver shall not be applicable after the occurrence and during the
continuance of an Event of Default.
