use to any right to such other party or parties on connection with, any
transaction contemplated by this Agreement or (4) agree to provide any Cross
Segment Service (as such term is defined in the Subcontract Agreement) other
than in the ordinary course of business;”
10.    Amendment to Sections 8.2(h) of the Original Agreement. Section 8.2(h) of
the Original Agreement is hereby amended in its entirety to read as follows:
“    (h) Seller Parent and Buyer shall cause joint elections to be executed, in
the prescribed form and containing the prescribed information, under section 167
of the Excise Tax Act (Canada) (and under the corresponding provisions of any
similar provincial legislation) so that no material goods and services tax
and/or harmonized sales tax (or similar VAT in Canada) (collectively, “Canadian
VAT”) is payable under Part IX of the Excise Tax Act (Canada) (and under any
other similar provincial legislation) in respect of the purchase and sale of the
Purchased Assets being sold to Sheppard Canada Holdings N.S. ULC by Hewitt
Associates (including by Hewitt Associates Corp. as agent for and on behalf of
Hewitt Associates). Buyer shall cause Sheppard Canada Holdings N.S. ULC to file
any such elections within the time prescribed by the Excise Tax Act (Canada)
(and any other similar provincial legislation). Provided Sheppard Canada
Holdings N.S. ULC makes and files such elections, the Seller Parent agrees that
no tax shall be collectible under the Excise Tax Act (Canada) (“ETA”) (or
similar VAT legislation in Canada) on Closing in respect of the sale of the
Canadian Purchased Assets to Sheppard Canada Holding N.S. ULC by Hewitt
Associates (including by Hewitt Associates Corp. as agent for and on behalf of
Hewitt Associates). With respect to the Canadian Purchased Assets purchased by
Sheppard Canada Holdings N.S. ULC from Aon Hewitt Inc., Seller Parent and Buyer
agree that, on Closing, Aon Hewitt Inc. shall advance the amount of the Canadian
VAT collectible by it from Sheppard Canada Holding N.S. ULC with respect to the
purchase and sale of such assets (the “Advance”) and Sheppard Canada Holding
N.S. ULC shall direct Aon Hewitt Inc. to retain the Advance in satisfaction of
the payment of such Canadian VAT so collectible by Aon Hewitt Inc. Aon Hewitt
Inc. shall remit the amount of the Advance (or otherwise take into account the
Canadian VAT collected from Sheppard Canada Holding N.S. ULC in calculating its
net tax remittable for its Canadian VAT reporting period that includes the
Closing Date) to the Canada Revenue Agency (or other applicable taxing
authorities) in accordance with the applicable Requirements of Law. Seller
Parent and Buyer further agree that the Advance shall be repaid by Sheppard
Canada Holding N.S. ULC to Aon Hewitt Inc. within 7 business days after Sheppard
Canada Holding N.S. ULC receives a refund (or such refund is applied to reduce
other taxes payable by Sheppard Canada Holding N.S. ULC) of the Canadian VAT
from the Canada Revenue Agency (or other applicable taxing authorities) or, to
the extent that the Canadian VAT paid by Sheppard Canada Holding N.S. ULC to Aon
Hewitt Inc. reduces the net tax remittable for Canadian VAT purposes by Sheppard
Canada Holding N.S. ULC for its applicable Canadian VAT reporting period that
includes the Closing Date, within 7 business days after the filing due date of
Sheppard Canada Holding N.S. ULC’s Canadian VAT Tax Return in which it claims a
credit for such Canadian VAT. Seller Parent and Buyer agree that they will cause
Aon Hewitt Inc. and Sheppard Canada Holding N.S. ULC, respectively, to file
their Canadian VAT Tax Returns for the applicable Canadian VAT reporting period
that includes the Closing Date in accordance with the applicable Requirements of
Law and they will each account for (and in the case of Aon Hewitt Inc., remit)
the Canadian VAT collected by Aon Hewitt Inc. and paid by Sheppard Canada
Holding N.S. ULC to the fullest extent possible in such returns.”

8.4” shall be added immediately before the words “International Employees” in
Section 8.3(u) of the Original Agreement and the phrase “(a)” shall be added

in the positions identified on Schedule 1.1(e) (or any employees providing
services primarily to or on behalf of the business described in the last
sentence of the definition of HR and Other Related Communications Consulting
Services) to charge time to clients of the Business (other than shared clients
of the Business and the Selling Parties as of the Closing Date, solely with
respect to the types of services that are provided by such employees as of the
Closing Date).”
13.     New Section 8.15 of the Original Agreement: Section 8.15 is hereby
inserted into the Original Agreement so as to read in its entirety as follows:
“Section 8.15    Deidentified Data. For a period of two years following the

reasonable efforts to provide to Seller Parent or its applicable Affiliate, at
no cost to Seller Parent or any of its Affiliates, Deidentified Data reasonably
necessary for Seller Parent or its applicable Affiliate to conduct the research
related to Real Deal publication and to produce and publish the Real Deal

of client confidential information to third parties); provided that Seller
Parent shall reimburse Buyer for the cost of providing such Deidentified Data.
If any industry white papers produced or published by Seller Parent or its
Affiliates include references to or otherwise utilize Deidentified Data provided

applicable Affiliate shall attribute such Deidentified Data to Buyer. For
purposes of this Section 8.15, “Deidentified Data” means data related to a
natural person from which has been redacted or removed the natural person’s
