In connection with Cisco Systems, Inc.’s (“Cisco”) decision to eliminate the position of President, Development and Sales, and the position of President and Chief Operating Officer, on May 27, 2015, Robert W. Lloyd (President, Development and Sales) and Gary B. Moore (President and Chief Operating Officer) agreed to leave Cisco effective July 25, 2015, the end of fiscal 2015.

Mr. Lloyd and Mr. Moore entered into Separation Agreements each dated May 31, 2015 (the “Separation Agreements”). Each Separation Agreement provides that the executive will be eligible to earn his bonus under Cisco’s Executive Incentive Plan for fiscal year 2015 if he serves through the end of fiscal year 2015 and will be entitled to accelerated vesting of the time-based restricted stock unit awards which are scheduled to vest in September 2015 and September 2016. Subject to the terms and conditions of the respective Separation Agreement, each executive will also be entitled to the performance-based restricted stock unit award which will vest in September 2017 to the extent the performance goals are achieved. Additionally, each executive will be entitled to the following benefits under his Separation Agreement: (i) a cash payment equal to eighteen months of his annual base salary and target bonus award, or $2,200,000 for Mr. Lloyd and $2,268,750 for Mr. Moore, paid during calendar 2016; and (ii) an extension of the post-termination exercise period for any stock options with an exercise price greater than Cisco’s stock price upon separation of employment.

The foregoing descriptions of the Separation Agreements are qualified in their entirety by reference to the Separation Agreements, copies of which are filed as Exhibit 10.1 and 10.2 to this report.
