NOW, THEREFORE, in consideration of the respective agreements of the parties contained herein, the parties agree as follows:
1.
The first sentence of Section 1.10 of the Employment Agreement shall be superseded by and replaced in the entirety with the following:
During the term of this Agreement, Employee shall not be engaged prior to the Transition Date in any other employment nor directly or indirectly engage in any other business activities in any capacity for any other person, firm or company whether or not for consideration, without the express prior written consent of KLA; provided, however, that Employee may continue to (i) serve as a passive investor in the equity of any business, provided that Employee is not otherwise involved in running such business and (ii) act in any advisory capacity with respect to any business for which Employee currently serves in such role as of the Closing Date, or serve in any similar role with respect to any similar business, provided that no such business is a Competitor (as defined below). Notwithstanding the foregoing, during the period during which Employee holds the Position, he may serve as a director on the board of directors of up to two public or private companies, provided the applicable company is not a Competitor. Following the Transition Date, Employee may serve as a director on any number of public or private companies, provided the applicable company is not a Competitor, without the need to obtain the Company’s or KLA’s consent. In addition, beginning on and following the




Transition Date, Employee shall be permitted to engage in employment with another person, firm or company (including for consideration), provided that such person, firm or company is not a Competitor and such employment does not interfere with Employee’s ability to fulfill his responsibilities hereunder.

The amount of the Annual Bonus, if any, will depend on the achievement of the objectives set forth in Exhibit A1 (the “Annual Bonus Objectives”). The Annual Bonus Objectives for calendar year 2020 will be based in part on achievement of financial objectives for the Company established at a date following the date hereof and approved by the Compensation Committee of the Board of Directors of KLA (the “Compensation Committee”) within 45 days following the end of calendar year 2019, which Annual Bonus Objectives will be incorporated into Exhibit A1 as of the date of such approval.
