(b) Mark V. Mactas, the Company’s President and Chief Operating Officer, has provided notice to the Company of his intent to retire from the Company, effective during the fourth quarter of calendar 2011, with the specific date to be determined in the future.

Mr. Mactas has indicated that his primary goal and interest has been to ensure that the Company is positioned for long-term success, and that he firmly believes that to be the case. He also stated that he is therefore confident that he can take a step back later this year and watch Towers Watson thrive from a new vantage point. Over the coming months, Mr. Mactas will continue in his current role as president and chief operating officer. His areas of focus will remain the same — positioning Towers Watson for growth through his input into overall strategy, furthering the Company’s integration efforts and providing guidance in critical areas such as leadership development and succession planning.
