On September 29, 2006, Korn/Ferry International (the “Company”) entered into a letter agreement with Robert McNabb, an Executive Vice President of the Company and Chief Executive Officer of Korn/Ferry International Futurestep, Inc., modifying the terms of Mr. McNabb’s employment agreement. Under the employment agreement, dated October 1, 2003 (the “Employment Agreement”), the initial term of Mr. McNabb’s employment was to continue until October 1, 2006 and the Company could renew the agreement for successive one year periods. The letter agreement extends the initial term of Mr. McNabb’s employment until September 30, 2009 and amends the Company renewal option to a single three year period ending on September 30, 2012.

The letter agreement also modifies the Employment Agreement to provide, among other things, that if Mr. McNabb’s employment is terminated prior to a Change in Control (as defined in the Employment Agreement) by the Company without cause (as defined in the Employment Agreement) or by reason of the Company’s failure to exercise its renewal option, (i) Mr. McNabb will be entitled to the benefit of one times his then annual target cash bonus in addition to one times his base salary, (ii) the period of his and his dependent’s participation in the Company’s group health plans is extended from twelve to eighteen months and (iii) all outstanding stock options and other equity type incentives held by Mr. McNabb at the time of his termination that would have vested in twelve months following the date of termination, rather than in the calendar year of termination, will become fully vested and shall remain exercisable until their originally scheduled vesting dates. Additionally, the letter agreement adds to the Employment Agreement a one year non-competition provision which will apply to Mr. McNabb upon specified termination events.
