Item 1.01. Entry into a Material Definitive Agreement.

On September 23, 2010, Extreme Networks, Inc. (“Extreme Networks”) and Trumark Companies LLC (“Trumark”) entered into an Option Agreement in which Extreme Networks granted Trumark an option (the “Option”) to purchase approximately eight acres from the eastern portion of Extreme Networks’ corporate campus located at 3515-3585 Monroe Street, Santa Clara California (the “Subject Property”). Provided that Trumark makes required option payments, Trumark will have twenty-four months to exercise the Option. If Trumark exercises the Option, the closing on the purchase of the Subject Property will occur thirty days after such exercise; provided if the final map creating the Subject Property has not been recorded with the applicable authorities, then Trumark has the right to extend the closing in order to get the final map recorded for up to six subsequent periods of thirty days each by providing extension payments to Extreme Networks. The purchase price of the Subject Property at the closing will be calculated by multiplying the square footage of the Subject Property by $71.74 for an approximate purchase price of $24,000,000.

The disclosure contained under Item 1.01 hereof is incorporated by reference into Item 8.01 of this Current Report, as it may be deemed to include solicitation materials under Rule 14A of the Securities Exchange Act of 1934, as amended.
