(c) Amendment to Section 4.6. Section 4.6 of the Credit Agreement is hereby amended by deleting subsection (a) in its entirety and inserting the following in lieu thereof:

(a) Subject to the conditions set forth below, the Borrowers shall have the option, exercisable on no more than two (2) occasions from and after the Third Amendment Effective Date until May 10, 2006 to incur additional indebtedness under this Agreement in the form of an increase of the Term Loan Commitment to the amount of up to Two Hundred Fifty-Seven Million Nine Hundred Five Thousand Two Hundred Fifty Dollars ($257,905,250). The Company, on behalf of the Borrowers, by providing an Increase Notification, may request that additional Term Loans be made on the applicable Additional Term Loan Effective Date pursuant to such increase in the Term Loan Commitment (each such additional Term Loan, an “Additional Term Loan,” and collectively, the “Additional Term Loans”). The Borrowers, the Administrative Agent and the Lenders hereby agree and acknowledge that the Borrowers exercised the option set forth in this subsection (a) on the Third Amendment Effective Date in connection with the incurrence of the Second Additional Term Loans in the amount of Two Hundred Seven Million Nine Hundred Five Thousand Two Hundred Fifty Dollars ($207,905,250).

(d) Amendment to Section 5.1(c)(ii). Subsection (c)(ii) of Section 5.1 of the Credit Agreement is hereby deleted in its entirety and the following is substituted in lieu thereof:

(e) Amendment to Section 5.12. Section 5.12 of the Credit Agreement is hereby deleted in its entirety and the following is substituted in lieu thereof:

SECTION 5.12 Use of Proceeds.

(a) Except as otherwise permitted pursuant to Section 11.7(d) hereof, the Borrowers shall use the proceeds of the Extensions of Credit (i) to refinance the obligations under the Existing Credit Agreement as set forth herein, and (ii) for working capital and general corporate requirements of the Borrowers and their Subsidiaries,

2

including Permitted Acquisitions and the payment of certain fees and expenses incurred in connection with the transactions contemplated hereby.

(b) Notwithstanding the foregoing, the proceeds of the First Additional Term Loans shall be used (i) to refinance the Initial Term Loans on the Second Amendment Effective Date and (ii) to finance the acquisition of all of the capital stock of Imagine Technology Group, Inc. and its Subsidiaries on the Second Amendment Effective Date.

(c) Notwithstanding the foregoing, the proceeds of the Second Additional Term Loans shall be used to refinance the First Additional Term Loans on the Third Amendment Effective Date.”

3. Additional Term Loan Agreement. The Applicable Margin and the terms for repayment of the Second Additional Term Loans are set forth on the Schedule 1 attached hereto and in Articles IV and V of the Credit Agreement; provided that the terms set forth on Schedule 1 attached hereto shall control to the extent such terms conflict with the terms of Articles IV and V of the Credit Agreement. For the purpose of Section 4.6 of the Credit Agreement, this Amendment shall constitute the Additional Term Loan Agreement with respect to the Second Additional Term Loans.

4. Conversion of the First Additional Term Loans into the Second Additional Term Loans.

(a) The parties hereby agree that upon the Third Amendment Effective Date, the First Additional Term Loans of each Term Loan Lender that will hold Second Additional Term Loans on the Third Amendment Effective Date (each such Lender, a “Converting Lender”) shall, in the sole discretion of the Administrative Agent, be converted into Second Additional Term Loans, in each case in the amounts and the percentages, as applicable, set forth in the Register for such Converting Lender. In the event that, immediately after giving effect to the payments, conversions and reallocations on the Third Amendment Effective Date as contemplated by this Section 4(a), the outstanding principal amount of a Converting Lender’s Second Additional Term Loans will exceed the outstanding principal amount of such Converting Lender’s First Additional Term Loans immediately prior to giving effect to such payments, conversions and reallocations, then such Converting Lender shall make an advance in an amount equal to such excess. Furthermore, the Administrative Agent shall make such reallocations of outstanding Term Loans of each Converting Lender as are necessary in order that the Second Additional Term Loans of such Converting Lender reflect such Converting Lender’s Term Loan Commitment, in each case as set forth on the Register immediately after giving effect to the payments, conversions and reallocations contemplated in this Section 4(a).

(b) As of the Third Amendment Effective Date, after giving effect to the payments, conversions and reallocations described in Section 4(a), the aggregate outstanding amount of the Second Additional Term Loans shall be $207,905,250. The outstanding First Additional Term Loans of all Term Loan Lenders other than the Converting Lenders (the “Departing Lenders”)

3

shall be repaid in full from the proceeds of the Second Additional Term Loans and terminated and each such Departing Lender shall cease to be a Lender with respect to Term Loans under the Credit Agreement. In addition, on the Third Amendment Effective Date, the First Additional Term Loans shall be entirely re-evidenced and replaced with the Second Additional Term Loans. The Borrowers hereby agree that after the Third Amendment Effective Date, neither the Administrative Agent, the Syndication Agent, the Documentation Agent nor any Lender shall have any further obligations with respect to the First Additional Term Loans.

(c) All Term Notes issued by the Borrowers to any Term Loan Lender in connection with the First Additional Term Loans shall be promptly returned to the Administrative Agent who shall cancel such Term Notes and forward them to the Borrowers. Upon the request of any Term Loan Lender in connection with the Second Additional Term Loans, the Borrowers shall execute and deliver to such Term Loan Lender new Term Notes.

(d) To the extent any conversion, reallocation or prepayment provided in this Section 4 is deemed to conflict with any of the provisions of Articles IV or V of the Credit Agreement (including, without limitation, Section 4.6(d) of the Credit Agreement), any such conflicting provisions are hereby waived for purposes of this Amendment.

(e) The events and transactions described and contemplated in this Section 4 are not intended to, and shall not, constitute a novation of the Credit Agreement or any of the indebtedness incurred in connection therewith, including, without limitation, any Obligations.

5. Effectiveness. This Amendment shall become effective on the date that each of the following conditions has been satisfied:
