FIRST AMENDMENT TO THREE YEAR CREDIT AGREEMENT

This First Amendment to Three Year Credit Agreement (herein, the “Amendment”) is entered into as of September 29, 2003, by and among Hewitt Associates LLC, an Illinois limited liability company (the “Borrower”), the several financial institutions listed on the signature pages hereof, as Lenders, and Harris Trust and Savings Bank, as Administrative Agent (the “Administrative Agent”) for the Lenders.

PRELIMINARY STATEMENTS

A. The Borrower, the Lenders and the Administrative Agent are parties to a Three Year Credit Agreement dated as of September 27, 2002 (the “Credit Agreement”). All capitalized terms used herein without definition shall have the same meanings herein as such terms have in the Credit Agreement.

B. The Borrower has requested that the Lenders replace the Tangible Net Worth Covenant with a Total Debt to Total Capitalization Covenant, change certain financial reporting requirements and make certain other changes to the Credit Agreement, and the Lenders are willing to do so under the terms and conditions set forth in this Amendment.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

SECTION 1. AMENDMENTS.

Subject to the satisfaction of the conditions precedent set forth in Section 2 below, the Credit Agreement shall be and hereby is amended as follows:

1.1. The definition of “Applicable Margin” set forth in Section 4.1 of the Credit Agreement shall be amended by deleting the paragraph immediately following the pricing table set forth therein and replacing it with a new paragraph, to read in its entirety as follows:

For purposes hereof, the term “Pricing Date” means, for any fiscal quarter of the Borrower ending on or after September 30, 2002, the date on which the Administrative Agent is in receipt of the Borrower’s most recent financial statements (and, in the case of the year-end financial statements, audit report of the Borrower or HAI, as required under Section 7.5 hereof) for the fiscal quarter then ended, pursuant to Section 7.5 hereof. The Applicable Margin shall be established based on the Leverage Ratio for the most recently completed fiscal quarter and the Applicable Margin established on a Pricing Date shall remain in effect until the next

Pricing Date. If the Borrower has not delivered its financial statements by the date such financial statements (and, in the case of the year-end financial statements, audit report of the Borrower or HAI, as required under Section 7.5 hereof) are required to be delivered under Section 7.5 hereof, until such financial statements and audit report are delivered, the Applicable Margin shall be the highest Applicable Margin (i.e., the Leverage Ratio shall be deemed to be greater than 1.50 to 1.0). If the Borrower subsequently delivers such financial statements before the next Pricing Date, the Applicable Margin established by such late delivered financial statements shall take effect from the date of delivery until the next Pricing Date. In all other circumstances, the Applicable Margin established by such financial statements shall be in effect from the Pricing Date that occurs immediately after the end of the fiscal quarter covered by such financial statements until the next Pricing Date. Each determination of the Applicable Margin made by the Administrative Agent in accordance with the foregoing shall be conclusive and binding on the Borrower and the Lenders if reasonably determined.
