Fiscal Year 2017 6-Month Executive Incentive Plan

This KLA-Tencor Executive Incentive Plan (this “Plan”) is intended to motivate senior executives to achieve corporate objectives by providing a competitive bonus for target performance and potential upside for outstanding performance.

This Plan is effective for the 6-month period from July 1, 2016 through December 31, 2016 (the “Plan Period”). Newly eligible employees (e.g., employees promoted to an incentive-eligible position for the first time or a new hire) must be in an eligible position on or before October 1, 2016 and recorded in the HR system in order to qualify for participation in this Plan Period.

Eligible Positions
The Company’s Chief Executive Officer (“CEO”) and employees holding a position at the X02 level and above (collectively, with the CEO, “Executives”) are eligible to participate in the Plan.

Bonus payments, based on performance during the Plan Period, will be paid within 45 days following December 31, 2016. Bonus calculations are based on paid base salary for the applicable Plan Period. Paid base salary includes base salary and seasonal bonuses paid in some countries if the seasonal bonus is considered a component of the employee’s annual salary. Paid base salary does not include relocation allowances and reimbursements, tuition reimbursements, car/transportation allowances, expatriate allowances, commissions, long-term disability payments, or bonuses paid during the fiscal year. A participant must be a regular, active employee of the Company on the date of the payout in order to receive payment. Employees who are promoted or hired into an eligible position during the Plan Period (on or before October 1, 2016) will have their payouts calculated on paid salary from the effective date of the promotion or hire. If an employee’s target bonus changes during the year, the payout will be prorated.

A target bonus is established as a percent of base salary for each Plan participant.

Total available funding for the Plan will be determined by performance against a threshold level as measured by Balanced Scorecard and Operating Margin (“OM”)* performance for the Plan Period. The Plan will be fully funded (equivalent to the sum, for all Plan participants in the aggregate, of 2 times the product of each Plan participant’s target bonus percentage and base salary during the Plan Period) upon achievement of Operating Margin performance of $125M. This performance threshold constitutes the performance threshold for purposes of Section 162(m) of the Internal Revenue Code (“Section 162(m)”). This fully funded amount represents the maximum bonus opportunity for all Plan participants in the aggregate and the maximum total cost of the Plan.

The level of funding available for payment to participating Executives will be based on performance as measured against the Corporate Balanced Scorecard and OM performance, as provided in the table (“FY17 6-month Executive Bonus Payout Table”) below. Amounts in the table represent the multiple of each participating Executive’s target bonus available for allocation of bonus payments, subject to any positive or negative adjustment based on such Executive’s IPM (as defined below).

The actual bonus payment amount for each individual Executive (other than the CEO) will be based on the CEO’s assessment of the Executive’s performance for the Plan Period and determination of an Individual Performance Multiplier (“IPM”) ranging from 80-120%. The IPM is multiplied by the Executive’s target bonus and the multiple achieved from the Performance Matrix above to determine the actual bonus payment amount (see bonus calculation below). Each Executive’s performance will be evaluated based on how effectively they led their organization as demonstrated against the key Balanced Scorecard measures and objectives for the Executive’s respective organization. The IPM and final bonus payments for each Plan participant who is an executive officer of the Company for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, with the exception of the CEO, will be recommended by the CEO and reviewed and approved by the Compensation Committee. The IPM and final bonus payment for the CEO will be determined and approved by the Company’s Board of Directors.

The formula for calculation of a participant’s actual bonus payment is:

Participant’s paid base salary for the Plan Period

x Participant’s target bonus percentage

x Payout multiple from the FY17 6-month Executive Bonus Payout Table

x Participant’s Individual Performance Multiplier (IPM)

The final bonus payments for each Plan participant who is an executive officer of the Company for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, with the exception of the CEO, will be reviewed and approved by the Compensation Committee. The final bonus payment for the CEO will be reviewed and approved by the Company’s Board of Directors. The final bonus payment for all other Plan participants will be reviewed and approved by the CEO.

In no event can a bonus payment to an individual participant exceed 2 times such participant’s target bonus (i.e., 2 times the product of (a) the participant’s paid base salary for the Plan Period times (b) the Participant’s target bonus percentage).

The Compensation Committee (or the independent members of the Company’s Board of Directors, within the meaning set forth in Section 162(m) (the “Independent Directors”)) shall be the Plan Administrator. The Compensation Committee (or the Independent Directors) shall make such rules, regulations, interpretations and computations and shall take such other action to administer the Plan as it may deem appropriate. The establishment of the Plan shall not confer any legal rights upon any employee or other person for a continuation of employment, nor shall it interfere with the rights of the Company to discharge any employee and to treat him or her without regard to the effect which that treatment might have upon him or her as a participant in the Plan.

This Plan shall be construed, administered and enforced by the Compensation Committee (or the Independent Directors), in its sole discretion. The laws of the State of California will govern any legal dispute involving the Plan. The Compensation Committee (or the Independent Directors) may at any time alter, amend or terminate the Plan, subject to the requirements of Section 162(m).

This Plan is adopted pursuant to the KLA-Tencor Performance Bonus Plan and sets forth the terms and conditions for the annual incentive program for Executives for the first 6 months of fiscal year 2017.
