The provisions of this plan are set forth in the Extreme Networks, Inc. Executive Change in Control Severance Plan and your Agreement to Participate in the Extreme Networks, Inc.

In addition, we are pleased to offer you the following additional terms of employment:

1.   For a period from April22, 2015 until June 30, 2016, the Company’s existing policy regarding severance terms upon a termination for convenience is hereby modified to provide for an additional six (6) months' of your then-current base salary (for a total of 12 months' of you then­ current base salary) to be paid to you in the event of your termination for convenience from the Company; and

b. The acceleration and vesting in full of all of your time-based equity awards; and

The acceleration and vesting of certain Market Stock Units ("MSUs") granted to you prior to your death or permanent disability, the actual number of shares which shall vest to be calculated as if your death or permanent disability occurs within a Change of Control Period and as if you were terminated in connection with the Change of Control (a "Double Trigger Event") pursuant to the terms of the MSU Grant

Notwithstanding any of the foregoing to the contrary, the severance payments discussed above (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,".

All other terms and conditions of your employment under you offer letter, employment agreement(s) and/or otherwise will remain in full force and effect, including, but not limited to the at-will nature of your employment. In addition, your obligations under your employee agreement(s) including the "Employee Inventions and Proprietary Rights Assignment Agreement" shall remain in full force and effect, except as noted above. This letter agreement cannot be modified or amended except by a subsequent written agreement signed by you and the Company; provided, however, that the Company may, in its sole discretion, elect to modify your title, compensation, duties, or benefits without any further agreement from you.

Congratulations on your promotion! And I look forward to your on-going leadership and helping us drive success and growth at Extreme Networks!
