successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to Cede & Co., as nominee for The

most recent Interest Payment Date to which interest has been paid or duly
provided for, semi-annually in arrears on each March 30 and September 30,
commencing on March 30, 2011 (each, an “Interest Payment Date”), at the rate
of 6.250% per annum, until the principal hereof is paid or made available for
payment.  The interest so payable, and

Security (or one or more predecessor Securities) is registered at the close of
business on a subsequent record date for the payment of such defaulted interest
established by the Company, notice whereof shall be given to Holders of
Securities of this series not less than 15 days prior to such subsequent record
date, such record date to be not less than five days preceding the date of
payment of such defaulted interest, or be paid at any time in any other lawful

thereto as such address shall appear in the Security Register.


 


The
Securities of this series are subject to redemption and repurchase at the
option of the respective Holders prior to the stated maturity as described on
the reverse hereof.


 


Reference
is hereby made to the further provisions of this Security set forth on the
reverse hereof, which further provisions shall for all purposes have the same
effect as if set forth at this place.


 


Unless
the certificate of authentication hereon has been executed by the Trustee
referred to herein by manual signature, this Security shall not be entitled to
any benefit under the Indenture or be valid or obligatory for any purpose.

This
Security is one of a duly authorized series of securities of the Company
entitled “6.250% Senior Notes due 2040” (herein called the “Securities”) issued
and to be issued in one or more series under an Indenture, dated as of September 10,
2010 (herein called the “Indenture”) between the Company and The Bank of New
York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee,” which
term includes any successor trustee under the Indenture), to which Indenture
and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered.  The
Securities of this series will initially be issued in the aggregate principal
amount of $                   .  The Company may, from time to time, without
the written consent of or notice to holders of the Securities of this series,
create and issue under the Indenture additional securities having the same
terms and conditions as the Securities of this series (other than the issue
date, the issue price and, to the extent applicable, the first date from which
interest on such additional securities shall accrue and the first interest
payment date for such additional securities) and such additional securities
shall be consolidated with and form a single series with the Securities of this
series.


 


The
Company may redeem the Securities of this series, in whole at any time, or in
part from time to time, at the Company’s option, on not less than 30 nor more
than 90 days’ notice, at a price equal to the greater of (1) 100% of
the principal amount of the Securities to be redeemed and (2) the sum of
the present values of the remaining scheduled payments of principal and
interest on the Securities to be redeemed (exclusive of interest accrued to the
date of redemption) discounted to the redemption date on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months), at a rate equal
to the sum of the applicable Treasury Rate (as defined below), plus 40 basis
points, plus, in each case, accrued and unpaid interest thereon to but
excluding the redemption date (each such redemption being an “Optional
Redemption”).


 


If
the Company has given notice of Optional Redemption as provided herein and in
the Indenture and funds for the redemption of any Securities of this series
called for Optional Redemption have been made available on the applicable
redemption date, such Securities will cease to bear interest on the date fixed
for redemption.  Thereafter, the only
right of the Holders of such Securities will be to receive payment of the
applicable redemption price.


 


The
Company will prepare and mail a notice of an Optional Redemption to each Holder
of Securities to be redeemed by first-class mail at least 30 and not more than
90 calendar days prior to the date fixed for such Optional Redemption. On and
after the redemption date for an Optional Redemption, interest will cease to
accrue on the Securities called for redemption (unless the Company defaults in
the payment of the redemption price).


 


“Comparable
Treasury Issue” means the United States Treasury security selected by the
Quotation Agent as having a maturity comparable to the remaining term of the
Securities to be redeemed that would be utilized, at the time of selection and
in accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining term of the
Securities.


 


4

















 


“Comparable
Treasury Price” means, with respect to any redemption date, (i) the
average of three Reference Treasury Dealer Quotations for such redemption date,
after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the Trustee is given fewer than five such Reference
Treasury Dealer Quotations, the average of all such quotations, or (iii) if
only one Reference Treasury Dealer Quotation is received, such quotation.


 


“Quotation
Agent” means the Reference Treasury Dealer appointed by the Company.


 


“Reference
Treasury Dealer” means each of Credit Suisse Securities (USA) LLC, Morgan
Stanley & Co. Incorporated, Banc of America Securities LLC, Deutsche
Bank Securities Inc. and RBS Securities Inc. (or their respective affiliates
that are Primary Treasury Dealers) and their respective successors; provided,
however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a “Primary Treasury Dealer”),
the Company will substitute therefor another Primary Treasury Dealer.


 


“Reference
Treasury Dealer Quotations” means, with respect to each Reference Treasury
Dealer and any redemption date, the average, as determined by the Trustee, of
the bid and asked prices for the Comparable Treasury Issue (expressed in each
case as a percentage of its principal amount) quoted in writing to the Trustee
by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the
third business day preceding such redemption date.


 


“Treasury
Rate” means, with respect to any redemption date, the rate per annum equal to
the semi-annual equivalent yield to maturity of the Comparable Treasury Issue,
assuming a price for the Comparable Treasury Issue (expressed as a percentage
of its principal amount) equal to the Comparable Treasury Price for such
redemption date.


 


If
for any reason (i) the Company’s merger with Hewitt Associates, Inc.
pursuant to the Agreement and Plan of Merger dated as of July 11, 2010
(the “Merger Agreement”) (the “Merger”) is not consummated on or prior to March 31,
2011 or the Merger Agreement is terminated at any time prior thereto, the
Company will redeem all the Securities of this series on the Special Mandatory
Redemption Date (as defined below) at a redemption price equal to 101% of the
aggregate principal amount of the Securities, plus accrued and unpaid interest
from the later of the date of initial issuance or the most recent date to which
interest has been paid or duly provided for, whichever is later, to but
excluding the Special Mandatory Redemption Date (subject to the right of
Holders on the relevant Regular Record Date to receive interest due on the relevant
Interest Payment Date) (such redemption being the “Special Mandatory Redemption”).


 


The
Company will cause the notice of Special Mandatory Redemption to be mailed,
with a copy to the Trustee, within five business days after the occurrence of
the event triggering the Mandatory Redemption to each Holder at its registered
address. If funds sufficient to pay the redemption price of all Securities to
be redeemed on the Special Mandatory Redemption Date are deposited with the
paying agent on or before the Special Mandatory Redemption Date, on and after
the Special Mandatory Redemption Date, the Securities will cease to bear
interest and all rights under the Securities shall terminate.  The provisions relating to Special Mandatory
Redemption set forth in this paragraph may not be waived or modified without
the written consent of Holders of at least 90% in principal amount of the
outstanding Securities of this series.


 


5

















 


The
“Special Mandatory Redemption Date” means the earlier to occur of (1) April 30,
2011, if the merger has not been completed on or prior to March 31, 2011,
or (2) the 30th day (or if such day is not a business day, the first
business day thereafter) following the termination of the Merger Agreement for
any reason.


 


If
a Change of Control Repurchase Event (as defined below) occurs, unless the
Company has exercised its Optional Redemption right by notifying the Holders of
the Securities to that effect, the Company shall make an offer (a “Change of
Control Offer”) to each Holder of the Securities of this series to repurchase
all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of
$2,000) of that Holder’s Securities on the terms set forth herein. In a Change
of Control Offer, the Company shall offer payment in cash equal to 101% of the
aggregate principal amount of the Securities repurchased, plus accrued and
unpaid interest, if any, on the Securities repurchased to the date of
repurchase (the “Change of Control Payment”). 
Within 30 days following any Change of Control Repurchase Event or, at
the Company’s option, prior to any Change of Control, but after public
announcement of the pending Change of Control, the Company shall send, by first
class mail, a notice to each Holder of the Securities, with a copy to the
Trustee, which notice shall govern the terms of the Change of Control
Offer.  Such notice shall state, among
other things, the purchase date, which date will be no earlier than 30 days and
no later than 90 days from the date that notice is mailed, other than as may be
required by law (a “Change of Control Payment Date”). The notice will, if
mailed prior to the date of consummation of the Change of Control, state that
the Change of Control Offer is conditioned on the Change of Control Repurchase
Event occurring on or prior to the applicable Change of Control Payment Date.


 


Holders
of Securities electing to have Securities purchased pursuant to a Change of
Control Offer will be required to surrender their Securities, with the form
entitled “Option of Holder to Elect Purchase” on the reverse of the Security
completed, to the Paying Agent at the address specified in the notice, or
transfer their Securities to the Paying Agent by book-entry transfer pursuant
to the applicable procedures of the Paying Agent, prior to the close of
business on the third Business Day prior to the Change of Control Payment Date.


 


The
Company will not be required to make a Change of Control Offer upon the
occurrence of a Change of Control Repurchase Event if a third party makes such
an offer in the manner, at the times and otherwise in compliance with the
requirements for an offer made by the Company and the third party repurchases
all Securities properly tendered and not withdrawn under its offer.


 


The
Company shall comply with the requirements of Rule 14e-1 under the
Securities Exchange Act of 1934 (the “Exchange Act”) and any other securities
laws and regulations thereunder to the extent those laws and regulations are
applicable in connection with the repurchase of the Securities as a result of a
Change of Control Repurchase Event. To the extent that the provisions of any
such securities laws or regulations conflict with the Change of Control Offer
provisions of the Securities, the Company shall comply with those securities
laws and regulations and will not be deemed to have breached its obligations
under the Change of Control Offer provisions of the Securities by virtue of any
such conflict.


 


On
each Change of Control Payment Date, the Company shall, to the extent lawful:


 


6

















 


·      accept for
payment all Securities or portions of such Securities properly tendered
pursuant to the Change of Control Offer;


 


·      deposit with
the paying agent an amount equal to the Change of Control Payment in respect of
all Securities or portions of Securities properly tendered; and


 


·      deliver or
cause to be delivered to the Trustee the Securities properly accepted together
with an Officer’s Certificate stating the aggregate principal amount of the
Securities or portions of the Securities being repurchased and that all
conditions precedent provided for in the Indenture to the Change of Control
Offer and to the repurchase by the Company of the Securities pursuant to the
Change of Control Offer have been complied with.


 


For
purposes of the Change of Control Offer provisions of the Securities, the
following terms will be applicable:


 


“Change
of Control” means the occurrence of any of the following: (1) the direct
or indirect sale, lease, transfer, conveyance or other disposition (other than
by way of merger or consolidation), in one or a series of related transactions,
of all or substantially all of the Company’s assets and the assets of the
Company’s subsidiaries, taken as a whole, to any person, other than to the
Company or one of its subsidiaries; (2) the consummation of any
transaction (including, without limitation, any merger or consolidation) the
result of which is that any person becomes the beneficial owner (as defined in Rules 13d-3
and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of
the Company’s outstanding Voting Stock or other Voting Stock into which the
Company’s Voting Stock is reclassified, consolidated, exchanged or changed,
measured by voting power rather than number of shares; (3) the Company
consolidates with, or merges with or into, any person, or any person
consolidates with, or merges with or into, the Company, in any such event
pursuant to a transaction in which any of the Company’s outstanding Voting
Stock or the Voting Stock of such other person is converted into or exchanged
for cash, securities or other property, other than any such transaction where
the shares of the Company’s Voting Stock outstanding immediately prior to such
transaction constitute, or are converted into or exchanged for, a majority of
the Voting Stock of the surviving person or any direct or indirect parent
company of the surviving person immediately after giving effect to such
transaction; or (4) the first day on which a majority of the members of
the Company’s board of directors are not Continuing Directors. Notwithstanding
the foregoing, a transaction will not be deemed to involve a Change of Control
under clause (2) above if (i) the Company becomes a direct or
indirect wholly-owned subsidiary of a holding company and (ii)(A) the
direct or indirect holders of the Voting Stock of such holding company
immediately following that transaction are substantially the same as the
holders of the Company’s Voting Stock immediately prior to that transaction or (B) the
shares of the Company’s Voting Stock outstanding immediately prior to such
transaction are converted into or exchanged for, a majority of the Voting Stock
of such holding company immediately after giving effect to such transaction.

Directors with the approval of a majority of the Continuing Directors who were
