(6)	The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices within the range from $111.7100 to $112.7099, 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)	This sale was effected pursuant to a Rule 10b5-1 trading plan previously adopted by the Reporting Person.
(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 8/27/2013 when the Reporting Person completed 12 months of continuous service, and 5% of the total number of shares have vested or will vest as the Reporting Person completes each 3-month period of continuous service thereafter.
