Dear Chris,

We are pleased to offer you the position of Executive Vice President, Chief Revenue Officer at Juniper Networks, Inc. (“Juniper” or the “Company”) reporting to Rami Rahim, Chief Executive Officer. Your primary work location will be Remote-TN; however, as the Company and needs of the business evolves, the exact location may change.

This offer is contingent upon a successful background investigation and reference checks as requested by the Company.

Your offer is composed of the following components:

Bonus: For the remainder of 2022, you will be eligible to participate in Juniper's 2022 Executive Annual Incentive Plan (the "Plan") with an annualized bonus target of 100% of your base salary actually paid in 2022. The actual amount of the bonus could be higher or lower than the bonus target depending on Company and individual performance. This Plan is a discretionary bonus program that Juniper funds based on the achievement of corporate financial results and strategic objectives established by Juniper. Once the total funding level is established by Juniper, the Compensation Committee (or a subcommittee thereof) of the Board of Directors (the “Committee”) will determine in its discretion any bonus amount for executive officers based on its assessment of corporate and individual performance. In addition, 50% of the actual cash payout under the Plan will be made in the form of a fully vested Juniper Restricted Stock Unit based on a conversion value previously established by the Committee for executive officers of the Company during the first fiscal quarter of this year. Accordingly, there is no specified or guaranteed amount that you will receive or become entitled to, and the Plan is subject to change or discontinuation at any time, and you must be employed by the Company on the date that any cash or equity incentive amount under the Plan is paid or granted in order to be eligible to receive such cash or equity incentive amount; provided that such amounts will be paid or granted on or before March 31, 2023.

Hiring Bonus: In addition, you will be offered a hiring bonus (less applicable withholding) in the amount of $1,000,000 payable in two installments. The first installment will be paid with your first or second paycheck and the second installment will be paid via payroll following your first-year anniversary. The bonus is conditional on your remaining employed over a two (2) year period. Should you voluntarily terminate your employment prior to one year of service with Juniper, you will be responsible for repayment (pro-rated) of the gross first installment bonus amount to the Company and you will not be eligible for the second installment. Should you voluntarily terminate your employment with Juniper after 12 months and within twenty-four months of employment, you will be responsible for repayment (pro-rated) of the total gross bonus amount to the Company.

Restricted Stock Units: Subject to compliance with applicable U.S. federal and state securities laws, you be granted the number of Restricted Stock Units (RSU) of Juniper Networks, Inc. Common Stock as indicated in the table above. You shall receive your grant on the third Friday of the month following the month in which your employment commences with the Company. The RSUs will vest cumulatively over a period of three years as long as you remain an employee of Juniper or one of its subsidiaries, with 34% of the shares vesting on the one-year anniversary of the vesting start date and 33% vesting on second and third anniversaries of the vesting start date. The RSU grant will be subject to your acceptance of an RSU award agreement, which, along with the Juniper equity incentive plan governing the RSU award and applicable sub-plans, will set out additional terms and conditions of the grant.

Arbitration: Any claim, dispute or controversy arising out of this agreement, the interpretation, validity or enforcement of this Agreement or the alleged breach thereof shall be submitted by the parties to final, binding and confidential arbitration by the American Arbitration Association (“AAA”), in San Francisco, California, conducted before a single arbitrator under the then-applicable AAA rules. By agreeing to this arbitration procedure, you and the Company waive the right to resolve any such dispute, claim or demand through a trial by jury or judge or by administrative proceeding. You will have the right to be represented by legal counsel at any arbitration proceeding. The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be available under applicable law in a court proceeding; and (b) issue a written statement signed by the arbitrator regarding the disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential findings and conclusions on which the award is based. The Company shall pay all AAA arbitration fees, except the amount of such fees equivalent to the filing fee you would have paid if the claim had been litigated in court. Nothing in this offer letter is intended to prevent either you or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any arbitration, including but not limited to any disputes or claims relating to or arising out of the misuse or appropriation of the Company’s trade secrets or confidential and proprietary information. Judgment may be entered on the award of the arbitration in any court having jurisdiction.

Very truly yours,

/s/ Rami Rahim

Chief Executive Officer

I accept the terms of this letter and agree to keep the terms of this letter confidential.
