11.10. Consent to Jurisdiction and Forum Selection. The parties hereto agree that all actions or proceedings arising in connection with this Agreement that result in judicial proceedings in accordance with Section 11.9 (inclusive) of this Agreement shall be tried and litigated exclusively in the state and federal courts located in the County of Santa Clara, State of California, U.S.A.

Each party hereby waives any
