Item 8.01 Other Events

On November 13, 2009, the board of directors of Watson Wyatt Worldwide, Inc., a Delaware corporation (“Watson Wyatt”), selected the remaining five of its six designees to the twelve-member board of directors of Towers Watson & Co. (“Towers Watson”, currently known as Jupiter Saturn Holding Company, or the “Holding Company”). These designees will become directors of Towers Watson immediately following completion of the mergers of Watson Wyatt and Towers, Perrin, Forster & Crosby, Inc. (“Towers Perrin”) with wholly-owned subsidiaries of Towers Watson pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 26, 2009, among Watson Wyatt, Towers Perrin, the Holding Company, Jupiter Saturn Delaware Inc. and Jupiter Saturn Pennsylvania Inc., as amended.

As provided in the Merger Agreement and previously disclosed in the joint proxy statement/prospectus included in the Registration Statement on Form S-4 (File No. 333-161705) (the “Registration Statement”) filed by the Holding Company with the Securities Exchange Commission (the “SEC”), Watson Wyatt previously selected John J. Haley, Watson Wyatt’s current Chief Executive Officer, President and Chairman of its board of directors, as one of Watson Wyatt’s designees to the Towers Watson board of directors. Mr. Haley is currently a member of the Towers Watson board of directors and will serve as Chief Executive Officer and Chairman of the Towers Watson board of directors immediately following completion of the mergers.

The designees selected by Watson Wyatt on November 13, 2009, include John J. Gabarro, Brendan R. O’Neill, Linda D. Rabbitt and Gilbert T. Ray, each of whom is currently an independent member of Watson Wyatt’s board of directors. Watson Wyatt also designated Gail E. McKee as a non-independent Towers Watson director.

Biographical information about each of Messrs. Gabarro, Haley, O’Neill and Ray and Ms. Rabbitt is included in Watson Wyatt’s Amendment to its Annual Report on Form 10-K/A filed with the SEC on October 20, 2009. Biographical information for Ms. McKee is provided below.

Gail McKee, age 50, has worked at Watson Wyatt for over 15 years. She is currently a managing consultant, and is a former Watson Wyatt board member. She has worked with large organizations on a broad range of domestic and international human resources programs for more than 20 years. Prior to joining Watson Wyatt, Ms. McKee worked for three years with The Walt Disney Company as the manager of international compensation and benefits, and prior to that position, as an account manager for Hewitt Associates for seven years. She holds a B.A. degree in English from the University of Washington and did graduate work at the business school at New York University. Ms. McKee is a Board of Trustee member of the Council on Employee Benefits, a founding member and President of the Human Resources Planning Society affiliate in the Pacific Northwest, and was a past member of the business school advisory board for Central Washington University.

As previously announced, Towers Perrin will designate the other six members of the Towers Watson board of directors. Pursuant to the Merger Agreement, one of these six designees is Mark V. Mactas, Towers Perrin’s President, Chief Executive Officer and Chairman of the board of directors. Mr. Mactas is currently a member of the Towers Watson board of directors and will serve as President, Chief Operating Officer and Deputy Chairman of the Towers Watson board of directors immediately following completion of the mergers. Towers Perrin will name five additional designees to the Towers Watson board at the effective time of the mergers, four of whom will be independent.
