 2011 EQUITY
INCENTIVE PLAN 
 STOCK UNIT AGREEMENT

 Pursuant to your Stock Unit Grant Notice (“Grant Notice”) and this Stock Unit Agreement (the
“Agreement”), Cymer, Inc. (the “Company”) has granted you a Stock Unit under Section 7(c) of the Cymer, Inc. 2011 Equity Incentive Plan (the “Plan”) for the number of
shares of the Company’s common stock (the “Common Stock”) indicated in the Grant Notice (collectively, the “Award”). Defined terms not explicitly defined in this Agreement but defined in the Plan
or Grant Notice will have the same definitions as in the Plan. 
 The details of your Award are as follows. 

1. DISTRIBUTION OF SHARES OF COMMON STOCK.
The Company will deliver to you a number of shares of Common Stock equal to the number of vested shares of Common Stock subject to your Award on the vesting date or dates provided in your Grant Notice; provided, however, that in the event that
the Company determines that you are subject to its policy regarding insider trading of the Company’s stock and any shares of Common Stock subject to your Award are scheduled to be delivered on a day (the “Original Distribution Date”)
that does not occur during an “open window period” applicable to you, as determined by the Company in accordance with such policy, then such shares shall not be delivered on such Original Distribution Date and shall instead be delivered as
soon as practicable within the next “open window period” applicable to you pursuant to such policy; provided, however, that unless the delay until the next open window period or the next day when you are not prohibited from selling shares
of the Company’s stock in the public market would not result in the imposition of any additional taxes under the Code (including section 409A of the Code), the delivery of the shares shall not be delayed pursuant to this provision beyond the
later of: (a) December 31st of the same calendar year of the Original Distribution Date, or (b) the 15th day of the third calendar month following the Original Distribution Date. 

2. CONSIDERATION. The Common Stock delivered to you pursuant to Section 1 of this Agreement shall be
deemed paid, in whole or in part, in consideration of your services to the Company in the amounts and to the extent required by law. 
 3. VESTING. Subject to the limitations contained herein, your Award will vest as provided in the Grant Notice, provided that vesting will cease upon the termination of
your Continuous Service. 
 4. NUMBER OF SHARES. The number
of shares of Common Stock subject to your Award referenced in your Grant Notice may be adjusted from time to time for Capitalization Adjustments as set forth in the Plan. 
 5. CONDITIONS TO ISSUANCE AND DELIVERY OF SHARES.
