Each Restricted Stock Unit represents the right to receive one share of KLA-Tencor Corporation common stock upon the satisfaction of the applicable vesting requirements set forth below.

Vesting Schedule:
You shall vest in the Restricted Stock Units annually, with 25% of the total value of the Restricted Stock Unit vesting on each of the 1st, 2nd, 3rd, and 4th annual anniversaries of the Date of Grant set forth above. Each vesting event is contingent upon your continued status as a current KLA-Tencor employee as of the applicable vesting date.

Vesting in your Restricted Stock Units will cease immediately upon your termination of Service Provider status for any reason, including pursuant to a reduction-in-force.

The issuance of shares of KLA-Tencor Corporation common stock upon the vesting of Restricted Stock Units is subject to compliance with all of the applicable requirements of all laws or regulations with respect to such units. Neither the grant of this award nor the vesting schedule alter the terms of your employment, which remain at-will and subject to termination by KLA-Tencor or you at any time, with or without cause or notice.
