Employee Stock Purchase Plan

May 5, 2015,

the Company’s stockholders approved the Varonis Systems, Inc.

2015

Employee Stock Purchase Plan (the “ESPP”), which the Company’s board of directors had adopted on

March 19, 2015.

The ESPP became effective as of

June 30, 2015.

The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to

15%

of their eligible compensation, at

not

less than

85%

of the fair market value of the Company’s common stock on the

first

day or last trading day in the offering period, subject to any plan limitations. The Company initially reserved

500,000

shares of common stock for issuance under the ESPP. The number of shares available for issuance under the ESPP was increased on

January 1, 2016,

and will increase each

January 1

thereafter, by an amount equal to the lesser of (i)

one

percent (

) of the number of shares of common stock issued and outstanding on each

December 31

immediately prior to the date of increase, except that the amount of each such increase will be limited to the number of shares of common stock necessary to bring the total number of shares of common stock available for issuance under the ESPP to

two

percent (

) of the number of shares of common stock issued and outstanding on each such

December 31,

or (ii)

400,000

shares of common stock. On

January 1, 2018,

2017

and

2016,

the share reserve under the ESPP was automatically increased by

188,813,

158,695

and

21,383

shares, respectively. The ESPP will continue in effect until the earlier of (i) the date when

shares of common stock are available for issuance thereunder or (ii)

June 30, 2025;

unless terminated prior thereto by the Company’s board of directors or compensation committee, each of which has the right to terminate the ESPP at any time.
