*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Each RSU represents a contingent right to receive one share of KLA common stock.
(2)	On August 5, 2021, the Reporting Person received a grant of RSUs. The RSUs vest 25% annually from the date of grant.
(3)	Does not include performance-based RSUs, if any, held by the Reporting Person for which an assessment has not yet been made regarding the achievement of the applicable performance goals. Any such holdings will be reported on a Form 4 within two business days of the date such assessment is made.
(4)	On August 2, 2018, in addition to the RSUs granted on that date that were subject only to service-vesting requirements (which RSUs were previously reported on a Form 4), the Reporting Person was alsogranted RSUs covering up to a maximum of 62,074 shares (based on 150% of the target shares of 41,383) of KLA common stock, subject to both performance-vesting and service-vesting requirements. On August5, 2021, KLA's Board of Directors determined the level at which the corporate performance goals were attained and, based on the assessment, determined that the number of shares subject to the RSUs is 55,453.
(5)	The Reporting Person vested fifty percent (50%) of the performance-based RSUs upon the date on which the KLA's Board of Directors determined the level at which the underlying performance goals were attained (August 5, 2021) and will vest in the remaining fifty percent (50%) upon his completion of four years of service following the award (August 2, 2022). The shares of common stock will be issued as the performance-based RSUs vest.
(6)	Each RSU represents a contingent right to receive one share of KLA-Tencor common stock.
(7)	Reflects the forfeiture of 7,365 shares underlying the award granted to the Reporting Person on April 11, 2019 to comply with the terms of KLA's 2004 Equity Incentive Plan. The underlying shares forfeited were forfeited from the shares that are scheduled to vest on April 11, 2025.
(8)	Pursuant to the terms of the grant, shares of KLA common stock were automatically withheld at vesting to cover required tax withholding. The fair market value of KLA common stock used for purposes ofcalculating the number of shares to be withheld was the closing price of KLA common stock as reported on August 5, 2021.
(9)	Shares held under the Wallace Living Trust u/a/d 03/27/01, as amended, a trust of which the Reporting Person is a trustee and beneficiary.
