Dear Remi:

We are pleased to offer you a position with Extreme Networks, Inc. (the “Company”) as the Chief Financial Officer, reporting to Ed Meyercord in the Company’s San Jose, California office. This offer and your employment relationship with the Company are subject to the terms and conditions of this offer letter (“Offer Letter”).

Should you decide to join us, your anticipated start date with Extreme will be November 26, 2018. This is an exempt position, which means that you will be expected to work the hours necessary, including extended hours, to complete your job duties. You will receive an annual salary of four hundred and twenty-five thousand dollars ($425,000), less applicable taxes and withholdings, paid twice monthly, in accordance with the Company’s normal payroll procedures. The Company may change your position, supervisor, duties, compensation, and work location from time to time as it deems appropriate.

In addition, you will receive a sign-on bonus of $100,000.00, less applicable taxes and withholdings, on the second pay period following your first day of employment with the Company. Should you voluntarily terminate your employment with the Company, or if you are terminated from the Company for cause, prior to your second anniversary, you will be required to repay the sign-on bonus.

Company Bonus Plan

As an employee of the Company, you will be eligible to participate in the Extreme Incentive Bonus Plan with a target of 75% of your eligible earnings received during the plan’s performance period, less applicable taxes and withholdings. Eligible earnings generally include regular and premium wages received for time worked, and paid time off including observed holidays and vacations. Eligible earnings generally do not include business reimbursements, allowances, accrued retirement or severance benefits, or payments made to you by third party insurers even when these payment types are available to you because of your employment with the Company. Your payout is subject to the achievement of specific corporate performance objectives and the eligibility requirements of the Extreme Incentive Bonus Plan, and may be adjusted based on your personal contributions and performance. You must be an active employee of the Company at the time of payout to participate in and receive the Incentive Bonus Plan payout. The terms and conditions of the then-current Extreme Incentive Bonus Plan control any calculation and payout, and Company reserves the right to amend or terminate the Extreme Incentive Bonus Plan and/or any component of the Extreme Incentive Bonus Plan at any time and for any reason, without advance notice to any employee.

You will be eligible, as determined by the Compensation Committee of the Board of Directors, to receive a pro-rated bonus for the 1^st half of fiscal year 2019.

Time-Vesting Restricted Stock Units

Subject to the approval of the Compensation Committee of the Company or its delegate, you will receive a grant of 357,142 Restricted Stock Units (“RSUs”) (“Initial Grant”) that will vest fully over three (3) years with one-third (1/3) of the RSUs vesting upon the one (1) year anniversary of the vesting commencement date and the remaining RSUs vesting quarterly thereafter. Generally, grants are reviewed for approval once a quarter. Each RSU constitutes the right to receive one share of Company common stock upon vesting. All vesting rights to any RSUs offered hereunder will also be subject to your continued employment with the Company at the time of vesting. Your RSU grant is further conditioned on your execution of the Company’s standard form of employee RSU Agreement, and will be governed by and subject to the terms of that RSU Agreement and the Company’s 2013 Equity Incentive Plan and the terms of the Company’s Change in Control Severance Plan.

The Initial Grant is the number of RSUs which is the value equivalent to approximately $2,000,000.00 USD. The number of RSUs is calculated by dividing the RSU value equivalent by the average of the closing price during the previous 30 trading days. That number is rounded down to the next whole number to get the number of RSUs. This calculation is made as of November 14, 2018.

You will be eligible for an annual refresh grants, as determined by the Compensation Committee of the Board of Directors.

Executive Change in Control Severance

The Company also has a policy of providing a Change in Control Severance Plan for its executive officers in the event of an acquisition of the Company. Those provisions will be set forth in your Executive Change in Control Severance Agreement and will be the same as those standard terms currently in effect for the other executive officers of the Company with your benefit including a payment equal to 13 months of salary. A copy of the Change in Control Severance Plan has been enclosed for your information.

Termination Other than for Cause

If your employment is terminated by the Company other than for Cause not related to a Change in Control, you will be entitled to receive a severance payment equal to 6.5 months of your base salary as of your date of termination and up to 2 months of COBRA subsidy. Any such severance consideration shall be conditioned in its entirety upon your release of claims against the Company Group. Your release of claims document must be executed and become irrevocable within sixty (60) days of your termination and the payment due to you shall be paid within 30 days following the date the release has become irrevocable. “Cause” means the occurrence of any of the following:

(2) your material failure to abide by the Code of Conduct or other policies (including, without limitation, policies relating to confidentiality and reasonable workplace conduct) of any member of the Company Group;

(3) your misconduct within the scope of Section 304 of the Sarbanes-Oxley Act of 2002 as a result of which of the Company is required to prepare an accounting restatement;

(5) any intentional act by you which has a material detrimental effect on reputation or business of a member of the Company Group;

(6) your repeated failure or inability to perform any reasonable assigned duties after written notice from a member of the Company Group of such failure or inability;

(7) any material breach by you of any employment, non-disclosure, non-competition, non-solicitation or other similar agreement between you and a member of the Company Group, which breach is not cured pursuant to the terms of such agreement or as provided herein; or

(8) your conviction (including any plea of guilty or nolo contendere) of any criminal act involving fraud, dishonesty, misappropriation or moral turpitude, or which impairs your ability to perform your duties with a member of the Company Group,

provided, however, that prior to any determination that “Cause” has occurred, the Company shall (i) provide to you written notice specifying the particular event or actions giving rise to such determination and (ii) provide you an opportunity to be heard within 15 days of such notice and (iii) provide you with 15 days to cure such event or actions giving rise to a determination of “Cause”, if curable.

Notwithstanding anything in this agreement to the contrary, the severance payments discussed in this agreement (to the extent that they constitute “deferred compensation” under Section 409A of the Internal Revenue Code (the “Code”) and applicable regulations), and any other amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code and that would otherwise be payable hereunder by reason of your termination of employment, will not be payable to you by reason of such circumstance unless the circumstances giving rise to such termination of employment meet any description or definition of “separation from service” in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting or the determination of the amounts owed to you due to such termination, and if this provision prevents the payment of any amount or benefit to you, such payment shall be made on the date on which an event occurs that constitutes a Section 409A “separation from service”.
