                                                                  EXECUTION COPY


                              HEWITT ASSOCIATES LLC

                          FIRST AMENDMENT AND WAIVER TO
                             NOTE PURCHASE AGREEMENT

                                   $50,000,000
                               7.45% Senior Notes
                                due May 30, 2008


                                                        Dated as of May 31, 2002


To the Holders of the Senior Notes,
  of Hewitt Associates LLC Named in
  the Attached Schedule I

Ladies and Gentlemen:

       Reference is made to the Note Purchase Agreement dated as of May 1, 1996
among Hewitt Associates LLC, a limited liability company organized under the
laws of Illinois (the "Company"), and each of the Purchasers named in Schedule A
thereto (the "Note Agreement"), pursuant to which the Company issued
$50,000,000 aggregate principal amount of its 7.45% Senior Notes due May 30,
2008 (the "Notes"). You are referred to herein individually as a "Holder" and
collectively as the "Holders." Capitalized terms used and not otherwise defined
in this Amendment and Waiver shall have the meanings ascribed to them in the
Note Agreement.

     All of the ownership interests of the Company are owned by Hewitt Holdings
LLC (the "Parent"). The Parent has formed Hewitt Associates, Inc., a Delaware
corporation ("Associates") and owns all of the issued and outstanding common
stock of Associates. The Parent has caused Associates to file a registration
statement for the underwritten public offering of common stock of Associates
(the "IPO"). In preparation for the IPO, the Parent proposes among other things
to (i) cause the Company to distribute (the "Distribution") cash in the amount
of $55,000,000 and accounts receivables in the face amount of $152,500,000 to
the Parent which the Parent will use to fund a partial distribution of
undistributed accumulated earnings to the owners of the Parent and (ii) transfer
to Associates all of the ownership interests of the Company to Associates so
that the Company will become a wholly owned subsidiary of Associates. The
Distribution will cause the Company to be in violation of Section 10.3 of the
Note Purchase Agreement.

     The Company has requested the waiver of compliance with Section 10.3 and
the modification of certain financial covenants and other provisions of the Note
Agreement. The

<PAGE>

Holders are willing to grant an amendment and waiver on the terms and conditions
hereinafter set forth.

         In consideration of the premises and for good and valuable
consideration, the receipt and sufficiency of which are acknowledged, the
Company and the Holders agree as follows:

1.       AMENDMENTS TO NOTE AGREEMENT

         1.1.   Amendment of Section 10.4. Section 10.4(c) of the Note Agreement
is amended to read in its entirety as follows:

                "(c)    Funded Indebtedness provided that the Company will not
         permit at any time the ratio of Consolidated Funded Indebtedness to
         Consolidated Cash Flow for the most recently completed four fiscal
         quarters to exceed 2.25 to 1.0."

         1.2.   Amendment of Section 10.5. The text of Section 10.5 of the Note
Agreement is deleted in its entirety and replaced by the word "Reserved."

         1.3.   Amendment of Section 11. Section 11 of the Note Agreement is
amended to include the following clause (k):

                "(k)    Hewitt Holdings LLC defaults in the performance of or
         compliance with any term contained in the Parent Guaranty dated as of
         May 31, 2002 in favor of the holders of the Notes or such Parent
         Guaranty ceases to be in full force and effect (except as set forth
         therein with respect to the release thereof), or is declared to be
         null and void in whole or in part by a court or other governmental or
         regulatory authority having jurisdiction or the validity or
         enforceability thereof shall be contested by any of the Company or
         Hewitt Holdings LLC or any of them renounces any of the same or
         denies that it has any or further liability thereunder."

         1.4.   Amendment of Schedule B.

                1.4.1.  The definitions of "Current Indebtedness" and "Total
         Capitalization" are deleted from Schedule B.

                1.4.2.  The following terms are added to Schedule B:

                        "Consolidated Cash Flow" means, for any period, the sum
         of Consolidated Net Income for such period, plus, to the extent
         deducted in determining such Consolidated Net Income, (i) Consolidated
         Interest Expense, (ii) federal, state, local and foreign income,
         value added and similar taxes, (iii) depreciation and amortization
         expense, (iv) impairment charges relating to goodwill, (v) non-cash
         charges and (vi) foreign currency translation adjustments.

                        "Consolidated Interest Expense" means, for any period,
         the consolidated interest expense of the Company and its Restricted
         Subsidiaries for

                                       2

<PAGE>

     such period determined in accordance with GAAP (including imputed interest
     on Capital Lease obligations and all debt discount and expense amortized in
     such period).

          1.4.3. The definition of "Consolidated Net Capital" is amended to read
     in its entirety as follows:

                 "Consolidated Net Capital" shall mean the consolidated members'
     capital of the Company, as determined in accordance with GAAP, less
     Restricted Investments in excess of 20% of consolidated members, capital of
     the Company; provided, however, that "Consolidated Net Capital" shall not
     include any capital stock of Hewitt Associates, Inc. or Hewitt Holdings
     LLC.

2.   WAIVER

     The Holders waive compliance by the Company with the provisions of Section
10.3 of the Note Agreement solely as a result of the Distribution until the
earlier to occur of (i) the occurrence of a Default or Event of Default under
the Note Agreement and (ii) delivery by the Company of financial statements
pursuant to Section 7.1(a) or (b) of the Note Agreement, accompanied by
certificate required by Section 7.2 of the Note Agreement, demonstrating that
the Company is then in compliance with Section 10.3, without regard to such
waiver and that there exists no Default or Event of Default. During the period
the foregoing waiver is in effect, the Company will not at any time permit
Consolidated Net Capital to be less than the sum of (a) $25,000,000 plus (b)
the cumulative sum of 10% (without deduction for any loss) of its Consolidated
Net Income for the three-month period ending September 30, 2002 and for each
fiscal year thereafter. This waiver is limited to its terms and shall not
constitute a waiver of any other term, condition, representation or covenant
under the Note Agreement or any of the other agreements, documents or
instruments executed and delivered in connection therewith.

3.   REAFFIRMATION; REPRESENTATIONS AND WARRANTIES

     3.1. Reaffirmation of Note Agreement. The Company reaffirms its agreement
to comply with each of the covenants, agreements and other provisions of the
Note Agreement and the Notes, including the additions and amendments of such
provisions effected by this Amendment and Waiver.
