Item 5.02(e) Amendment of Agreements with Principal Executive Officer On March 9, 2007, the employment contract of Joseph J. Plumeri, Chairman and Chief Executive Officer of the Company, was extended by a further year to October 15, 2009. On June 20, 2006 the Company granted to approximately 140 Associates including the Chairman and Chief Executive Officer, Joseph J. Plumeri, options to purchase Willis shares at $32.78 per share, being the closing price of the Company's shares quoted on the New York Stock Exchange on the date of grant. Mr. Plumeri received an option grant to purchase 500,000 Willis shares and provided his employment is maintained, the option vests in equal tranches on the second to fifth anniversaries of the date of grant and remains exercisable until the eighth anniversary of the date of grant. On March 9, 2007, the option agreement was amended to change the definition of `Retirement' or `Retired' to be the same as the definition that Mr. Plumeri had in his previous option agreements and his employment agreements since June 2003. Further, the option agreement was amended to the effect that, on termination of employment as a result of retirement, if at that time a successor Chief Executive Officer has been appointed by the Board, the option shall become fully vested and exercisable for a period of two years following such termination. In the event Mr. Plumeri continues his employment as Executive Chairman after a successor Chief Executive Officer has been appointed, and afterwards ends his employment as a result of retirement, the same option schedule would apply. Item 8.01 Other Events On March 12, 2007, Willis Group Holdings Limited ("WGHL") issued a press release (the "Press Release") announcing that it has amended the employment agreement with its Chairman and Chief Executive Officer, Joseph J. Plumeri, to extend its term for an additional year. The employment agreement, which was scheduled to expire October 15, 2008, will now expire October 15, 2009. A copy of the Press Release is attached as Exhibit 99.1 to this Report on Form 8-K and is incorporated herein by reference. Item 9.01 Financial Statements and Exhibits.
