In the event that such a dispute arises, counsel for both Employee and Company will attempt to jointly select an arbitrator. If unable to do so, the procedures outlined in the AAA’s National Rules shall govern. Unless otherwise agreed to by Employee and Company, the arbitration shall take place in AAA’s office closest to the Company’s Seattle, Washington office.

13. Employee and Company acknowledge that Employees services were of a special and unique character and nature and that a breach of Sections 4, 10 and 11 of this Agreement or of Employee’s Proprietary Information and Inventions Agreement may cause irreparable injury and damage to the Company. In the event of such a breach, the Company shall be entitled to a temporary restraining order and injunctive relief.
