Mr. Helmut Wilke

[***]

Dear Helmut:

We are pleased to offer you a position with Extreme Networks (the “Company”) as Senior Vice President Worldwide Sales and corporate officer, reporting to me, Mark Canepa. Should you decide to join us, you will receive a semi-monthly salary of $11,458.33 (which would equal $275,000 on an annualized basis), less applicable taxes and withholdings, in accordance with the Company’s normal payroll procedures. In addition, you will receive a deferred sign-on bonus of $12,500, less applicable taxes and withholdings, upon completion of your first 175 consecutive days of employment with the Company and an additional $12,500, less applicable taxes and withholdings, upon the first anniversary of your date of hire.

As Senior Vice President Worldwide Sales, your full annual variable compensation at attainment of 100% of the Company’s FY’07 Sales Revenue Plan will be $175,000 (less all applicable taxes and withholding). Given a worldwide FY’07 revenue goal of $387,000,000, your commission rate will be .0452% of each revenue dollar. You will also be eligible to participate in the FY07 Executive Bonus Plan (EIP) with an annual target of $75,000. This annual target amount will be pro-rated by your amount of time as a regular employee in your first fiscal year of participation in the plan (FY2007). The pro-rata EIP target bonus will be paid if you and the Company meet established performance objectives tied to Gross Margin, Employee Attrition and Operating Profit performance. Details of the fiscal year 2007 Executive Incentive Program will be provided to you after you begin your employment with the Company. Your EIP performance metrics will be established shortly following your start date with the Company. The Company retains the right to change or amend the EIP at any time.

As a Company employee, you are also eligible to receive certain employee benefits including stock options. Subject to the approval of the Board of Directors, you will be granted a one-time option to acquire 500,000 (Five hundred thousand) shares of Common Stock. The exercise price of these shares will be equal to the closing price of the Common Stock on the date determined by the Board of Directors. One-fourth (1/4) of these shares will vest one year from your date of hire, provided that you are still employed by the Company at that time. The remaining shares will vest monthly over the following three years, at a rate of 1/48th of the entire option each month, so long as your employment with the Company continues. The grant will be subject to the terms and conditions of the Company’s stock option agreements. You agree to execute all agreements necessary to effectuate this grant.

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 currently in effect for the other executive officers of the company. A copy of the Plan document has been enclosed for your information.

If you choose to accept this offer, your employment with the Company will be voluntarily entered into and will be for no specified period. As a result, you will be free to resign at any time, for any reason or for no reason, as you deem appropriate. The Company will have a similar right and

may conclude its employment relationship with you at any time, with or without cause. This letter, along with any agreements relating to proprietary rights between you and the Company, set forth the terms of your employment with the Company and supersede any prior representations or agreements, whether written or oral. This letter may not be modified or amended except by a written agreement, signed by the Company and by you.

The Company also agrees that you will have a severance arrangement as follows: In the event that you are terminated by the Company at any time other than for cause, the Company will pay you the equivalent of six (6) months base salary. Termination for cause would include but is not limited to, incidences of fraud or commission of a felony, failure to attend work on a regular basis, a material breach of the Company’s policies or failure to follow a specific written instruction from the President, CEO or the Board of Directors. You agree that as a condition to receiving such payment, you will sign a release of claims.

In the event of any dispute of claim relating to or arising out of your employment relationship with the Company, this agreement, or the termination of your employment with the Company for any reason (including, but not limited to, and claims of breach of contract, defamation, wrongful termination or age, sex, sexual orientation, race, color, national origin, ancestry, marital status, religious creed, physical or mental disability or medical condition or other discrimination, retaliation or harassment), you and the Company agree that all such disputes shall be fully resolved by confidential, binding arbitration conducted by a single arbitrator through the American Arbitration association (“AAA”) under the AAA’s National Rules for the Resolution of Employment Disputes then in effect, which are available online at the AAA’s website at ww.adr.org. You and the Company hereby waive your respective rights to have any such disputes or claims tried before a judge or jury. Notwithstanding the above, however, we agree that this arbitration provision shall not apply to any disputes or claims relating to or arising out of the misuse or misappropriation of the Company’s trade secrets or proprietary information.

This offer is contingent upon your signing the enclosed Employee Inventions and Proprietary Rights Assignment Agreement, and upon your ability to provide to the Company documentary evidence of your identity and eligibility for employment in the United States.
