Dear Byrne,

This letter supersedes your existing offer letter with Korn Ferry International, dated March 15, 2010 (the “Original Offer Letter”), with respect to your continued employment with Korn Ferry International (“Korn Ferry” or the “firm”) as CEO, Futurestep. This letter is effective as of the date hereof.

Base Salary

Effective as of June 26, 2014 your monthly base salary will be $37,500.00, payable in semi-monthly increments. In addition, you will no longer be entitled to the management stipend set forth in the Original Offer Letter.

Annual Incentive Award

You will be eligible for an annual incentive award of up to $1,350,000 (cash and LTIP) with a target annual incentive award of $650,000 (cash and LTIP). This award will be based on an appraisal of your achievements in meeting goals established by the Compensation and Personnel Committee of the Board of Directors and such other factors as may be determined in the discretion of the Compensation and Personnel Committee.

Employee Benefits and Perquisites

You will continue to be eligible to participate in such employee benefit plans, arrangements and programs maintained by Korn Ferry from time to time for the benefit of its senior executives generally, including four weeks paid vacation and three weeks paid sick leave. In addition, you will continue to receive $450 per month as an automobile allowance. Please be aware that these programs are subject to change. If they are modified in the future, you will continue to be eligible for such benefits as are provided to other divisional CEO’s of the firm.

Severance

Your employment with Korn Ferry International remains an employment “at will” and this arrangement may be altered only in writing by an appropriate senior executive of Korn Ferry International. However, in the event that your employment with Korn Ferry is terminated (i) by Korn Ferry for any reason other than Cause (as defined below) or your

death or disability or (ii) by you for Good Reason (as defined below), and such termination of employment occurs prior to or more than 12 months after the occurrence of a Change in Control (as defined below), then Korn Ferry will pay to you your Accrued Compensation (as defined below), payable within 30 days after your termination (with the payment date during such 30 day period to be determined by Korn Ferry in its sole discretion), and a pro rata portion of the annual cash incentive award you would have received for the fiscal year in which your employment terminates (based on Korn Ferry’s actual performance over the entire year and the number of days of your actual service to Korn Ferry during such fiscal year), which pro rata portion will be payable to you at the same time bonuses are paid to executives generally for the applicable fiscal year, and

(1) Korn Ferry will pay to you the amount in cash equal, in the aggregate, to your then current annual base salary, in arrears in equal monthly installments over a period of twelve (12) months after the date your employment terminates;

(2) for up to eighteen (18) months after such termination, to the extent you and/or your covered dependent(s) continue to participate in Korn Ferry’s group health plan(s) pursuant to COBRA after your termination of employment and to the extent permitted by applicable law, Korn Ferry will provide reimbursement of COBRA coverage premiums paid by you and your covered dependent(s) so that you and your covered dependent(s) enjoy coverage at the same benefit level and to the same extent and for the same effective contribution, if any, as participation is available to other executive officers of Korn Ferry;

(3) outstanding equity incentive awards held by you (other than any performance shares) and all of your benefits under the Executive Capital Accumulation Plan at the time of your termination that would have vested in the twelve (12) months following the date your employment terminates (in each case, as if such incentives and benefits permitted proportionate vesting in monthly increments rather than any longer increment) will become fully vested as of the date your employment terminates and, to the extent applicable, shall remain exercisable until the date that is the earlier of (x) two (2) years after the date your employment terminates and (y) its originally scheduled expiration date; and

(4) you shall receive a number of performance shares and/or a payout under any long-term performance-based cash incentive program (as applicable), payable no later than the March 15 of the year following the calendar year in which the applicable performance period ends, equal to the product of (A) the performance shares and/or cash award that would have been earned if you had served Korn Ferry for the entirety of any open performance period at the time of your termination of employment based upon Korn Ferry’s actual performance during such period, and (B) a fraction, (x) the numerator of which fraction shall be the sum of (i) the number of days of your employment during any such performance period and (ii) 365 (provided that the numerator shall not exceed the number of days in the applicable performance period) and (y) the denominator of which fraction shall be the number of days in the applicable performance period (as determined in the sole discretion of the Compensation Committee of the Board of Directors of Korn Ferry).

In addition, if your employment with Korn Ferry is terminated (i) by Korn Ferry for any reason other than Cause or your death or disability or (ii) by you for Good Reason, and such termination of employment occurs within 12 months after the occurrence of a Change in Control (as defined on Schedule A hereto), then you will be entitled to the same severance benefits as described above, except that the aggregate payment in clause (1) above shall be in the amount equal to your then current annual base salary plus your target annual incentive award, and you will be entitled to vesting of 100% of your outstanding equity incentive awards and all benefits under the Executive Capital Accumulation Plan, provided that with respect to performance-based awards such vesting will be based on actual performance through the date of the Change in Control.

In the event that your employment is terminated by Korn Ferry for Cause, by you without Good Reason or as a result of your death or disability, you will not be entitled to the severance compensation described above, but instead will only be entitled to payment of the Accrued Compensation through the date your employment terminates, payable within 30 days after your termination (with the payment date during such 30 day period to be determined by Korn Ferry in its sole discretion).

Notwithstanding anything in this letter to the contrary, other than the payment of the Accrued Compensation through the date of termination of your employment, you shall not be entitled to any severance payments or benefits hereunder (i) unless and until you execute and deliver to Korn Ferry, within forty-five (45) days of the date of termination of your employment, a unilateral general release of all known and unknown claims against Korn Ferry and its officers, directors, employees, agents and affiliates in a form acceptable to Korn Ferry, and such release becomes fully effective and irrevocable under applicable law, and (ii) unless you are, and continue to be, in compliance with the terms set forth below under the headings “Business Information and Non-Competition” and “Assignment of Inventions”. In addition, promptly following any termination of your employment (other than by reason of your death), you will deliver to Korn Ferry reasonably satisfactory written evidence of your resignation from all positions that you may then hold as an employee or officer of Korn Ferry or any affiliate.

For purposes of this letter:

“Accrued Compensation” means, as of any date, the amount of any unpaid base salary earned by you through the date of the termination of your employment and any annual cash incentive award earned by you, but not yet paid, for the most recently completed fiscal year prior to the termination of your employment.

“Cause” shall mean (a) conviction of any felony or other crime involving fraud, dishonesty or acts of moral turpitude or pleading guilty or nolo contendere to such charges, (b) reckless or willful behavior or conduct that causes or is reasonably likely to cause Korn Ferry material harm or injury or exposes or is reasonably likely to expose Korn Ferry to any material civil, criminal or administrative liability, (c) any material misrepresentation or false statement made by you in any application for employment, employment history, resume or other document submitted to Korn Ferry, either before, during or after employment, or (d) any material violation of Korn Ferry’s material written policies or procedures including those described under professional requirements below.

Mr. Byrne Mulrooney

You shall be deemed to have “Good Reason” to terminate your employment hereunder if, without your prior written consent, (A) Korn Ferry materially reduces your duties or responsibilities as Chief Executive Officer, Futurestep, or (B) Korn Ferry materially reduces your then current base salary or target annual incentive award as set forth herein (in each case, other than as part of an across-the-board reduction applicable to all “named executive officers” of Korn Ferry (as defined under Item 402 of Regulation S-K and to the extent employed by Korn Ferry at that time)). Prior to terminating for Good Reason, you are required to provide Korn Ferry with 30 days advance written notice of your intention to terminate employment for Good Reason, and Korn Ferry shall be permitted to cure any events giving rise to such Good Reason during such 30 day period, after which, if such event remains uncured, your employment must terminate within 30 days.

Section 409A Compliance

Notwithstanding any inconsistent provision herein, to the extent Korn Ferry determines in good faith that (a) one or more of the payments or benefits received or to be received by you pursuant hereunder in connection with your termination of employment would constitute deferred compensation subject to the rules of Internal Revenue Code Section 409A (“Section 409A”), and (b) that you are a “specified employee” under Section 409A, then only to the extent required to avoid your incurrence of any additional tax or interest under Section 409A, such payment or benefit will be delayed until the earlier of your death or the date which is six (6) months after your “separation from service” within the meaning of Section 409A. For purposes of Section 409A of the Code, each right to receive payment hereunder shall be treated as a right to receive a series of separate payments and, accordingly, any installment payment shall at all times be considered a separate and distinct payment. Anything herein to the contrary notwithstanding, the terms of this letter shall be interpreted and applied in a manner consistent with the requirements of Section 409A the regulations promulgated thereunder so as not to subject you to the payment of any tax penalty or interest which may be imposed by Section 409A of the Code and Korn Ferry shall have no right to accelerate or make any payment hereunder except to the extent such action would not subject you to the payment of any tax penalty or interest under Section 409A. If, under the terms of this Agreement, it is possible for a payment that is subject to Section 409A to be made in two separate taxable years, payment shall be made in the later taxable year.

Section 280G

Anything in this letter to the contrary notwithstanding, in the event it shall be determined that any payment, benefit or distribution made or provided by Korn Ferry or its affiliated companies to you or for your benefit (whether paid or payable or distributed or distributable pursuant to the terms hereof or otherwise) (a “Payment”) would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), or interest or penalties with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), then such Payments shall either (a) be delivered in full, or (b) subject to and in a manner consistent with the requirements of Section 409A of the Code, be reduced to the minimum extent necessary to ensure that no portion thereof will be subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state or local income and employment taxes and the Excise Tax, results in your receipt, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be subject to the Excise Tax. In the event that any Payments are to be reduced pursuant to this paragraph, then the reduction shall be applied as follows: (i) first, on a pro rata basis to your cash severance payments and your pro rata annual cash incentive award payment for the year of termination, (ii) second, on a pro rata basis to your equity incentive awards and (iii) third, to your benefits under the Executive Capital Accumulation Plan.
