(1) The sales reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan previously adopted by the Reporting Person and represent shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units (RSUs). These sales are mandated by the Issuer's election under its equity incentive plan to require the satisfaction of tax withholding obligations to be funded by a "sell to cover" transaction and do not represent discretionary trades by the Reporting Person.
(2) The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $108.9900 to $109.9899, inclusive. The Reporting Person undertakes to provide to Workday, Inc., any security holder of Workday, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range(s) set forth in this footnote of this Form 4.
(3) Includes 40,681 restricted stock units (RSUs) that entitle the Reporting Person to receive one share of Class A Common Stock per unit upon settlement, which will take place within 30 days of vesting, from original grants consisting of i) 92,984 RSUs with a grant date of 04/15/2014 which vested or will vest in eight (8) quarterly installments beginning 07/15/2016, and ii) 92,984 RSUs with a grant date of 04/15/2015 which vested or will vest as to 25% of the underlying shares on the one-year anniversary of grant and quarterly thereafter. All grants are subject to the Reporting Person's continued service with Workday on the applicable vesting dates.
(4) Includes 16 shares of Class A Common Stock that were purchased through the Issuer's Employee Stock Purchase Program.
(5) The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $110.0000 to $110.9999, inclusive. The Reporting Person undertakes to provide to Workday, Inc., any security holder of Workday, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range(s) set forth in this footnote of this Form 4.
(6) The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $111.0600 to $112.0599, inclusive. The Reporting Person undertakes to provide to Workday, Inc., any security holder of Workday, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range(s) set forth in this footnote of this Form 4.
(7) The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $112.1100 to $113.1099, inclusive. The Reporting Person undertakes to provide to Workday, Inc., any security holder of Workday, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range(s) set forth in this footnote of this Form 4.
(8) This stock option grant is under the Issuer's 2005 Stock Option Plan and vests as follows: 20% of the total number of shares vested on January 1, 2014 when the Reporting Person completed 12 months of continuous service, and 5% of the total number of shares vests as the Reporting Person completes each 3-month period of continuous service thereafter. This option grant will be exercisable in full or in part at any time, but the unvested portion is subject to the Issuer's right to repurchase the shares at the original exercise price in the event of termination of the Reporting Person's service for any reason.
