[Voicemail message to all associates of Hewitt Associates, Inc.]

Hello, this is Dale, with a brief message to all associates.

This is truly a landmark day for Hewitt ... for our clients, for our associates, and for our stockholders ... as well as for broader HR outsourcing in general.

Today our firm announced our intent to join forces with Exult, a leading provider of HR business process outsourcing services, to create an even stronger Hewitt Associates, even better positioned for future success.

This move creates tremendous opportunity for our firm.

Client demand for broader HR outsourcing services is accelerating, and some analysts predict that this market segment will grow at double digit pace over the next few years.

We're already an established player in this arena with our unique and successful Workforce Management solution. And now combining forces with Exult will further broaden our capabilities, enabling us to seize the growing market opportunity and offer clients the most comprehensive, the most flexible HR solutions available anywhere.

This merger is a move that clearly demonstrates—to our clients, our prospects, and our shareholders—our ongoing commitment to being "the most influential advisor and the leading service provider in the people business." Exult's remarkable capabilities and expertise both complement and enhance our own. Together, we will be a leader in broader HR outsourcing, and the best choice for clients seeking fully integrated HR solutions.

We intend to file a registration statement including a proxy statement and prospectus in connection with our proposed combination with Exult. You are urged to read these documents when they become available in a few weeks because they will contain important information about the transaction. Today's press release has instructions for obtaining copies of these documents as well as other information.

You can read the press release and learn more about this exciting news on The Source. Additionally, your business leader will share more details in upcoming communications.

From my perspective, "Hewitt and Exult" is truly a winning combination. I hope you share my excitement about this news—as well as my optimism for the future of our company and the opportunities that this provides for associates!

Thanks for listening, and have a great day!
