I want to thank you for your contributions to Juniper. Below you will find updated details of your compensation, including a special cash and RSU award.

Effective June 1, 2017, your base salary will be $460,000 which represents an increase of 12.2% to your current base salary of $410,159. You will receive an appropraite adjustment for the months of June and July based on your salary at that time. Your salary will continue to be paid in accordance with the company’s standard payroll practices.

You will continue to be a participant in Juniper’s 2017 Executive Annual Incentive Plan (the “AIP”) and 2017 50/50 Plan. Your annual target incentive under the AIP will continue to be 100% of your base salary.

Juniper wishes to award you a special cash bonus in the amount of $530,000 to encourage you to continue to make outstanding contributions to the Company. This cash award will be paid to you November 30, 2018, less applicable taxes, withholdings or other deductions, provided you (i) remain an active employee of Juniper (or one of its subsidiaries) through and including November 30, 2018 and (ii) do not voluntarily terminate your employment or are not terminated for “cause” prior to that date. In addition, in the event that a Change of Control (as defined in your then current change of control agreement (your “agreement”) with Juniper Networks, Inc. (“Juniper”)) occurs on or prior to November 30, 2018 and your Equity Compensation Awards (as defined in your agreement) are subject to accelerated vesting as a result of your termination from Juniper pursuant to the terms of your agreement, then at such time (if any) that you are entitled to receive your cash payment pursuant to the terms of your agreement, you will receive the special cash bonus (less applicable taxes, withholdings or other deductions) to the extent not previous paid to you. For purposes of this letter, “cause” will have the definition ascribed thereto in your then current severance agreement with Juniper, provided that if you are at any time prior to the payment of the special cash bonus not subject to a severance agreement with Juniper, “cause” will mean:

(i) an act of personal dishonesty taken by you in connection with your responsibilities as an employee and intended to result in substantial personal enrichment to you; or

(ii) you are convicted of, or plead nolo contendere to a felony; or

(iii) a willful act by you which constitutes gross misconduct and which is injurious to Juniper; or

(iv) following delivery to you of a written demand for performance from Juniper which describes the basis for Juniper’s reasonable belief that you have not substantially performed your duties, continued violations by you of your obligations to Juniper which are demonstrably willful and deliberate on your part.
