Any statements or representations to the contrary (and, indeed, any statements contradicting any provision in this letter) should be regarded by you as ineffective.

All arbitration hearings shall be conducted in San Francisco, California. THE PARTIES HEREBY WAIVE ANY RIGHTS THEY MAY HAVE TO TRIAL BY JURY IN REGARD TO SUCH CLAIMS. The parties further agree that any arbitrable claims shall be resolved on an individual basis, and you agree to waive your right, to the extent allowed by applicable law, to consolidate any arbitrable claims with the claims of any other person in a class or collective action. This Agreement does not restrict your right to file administrative claims you may bring before any government agency where, as a matter of law, the parties may not restrict the employee’s ability to file such claims (including, but not limited to, the National Labor Relations Board, Equal Employment Opportunity Commission, disputes solely before government agencies, claims under applicable workers’ compensation law, and unemployment claims). However, the parties agree that, to the fullest extent permitted by law, arbitration shall be final and binding on the parties and shall be the exclusive remedy for the subject matter of such administrative claims. The arbitration shall be conducted through JAMS before a single neutral arbitrator, in accordance with the JAMS employment arbitration rules then in effect. The Company agrees to pay the fees and costs of the arbitrator. The JAMS rules may be found and reviewed at http://www.jamsadr.com/rules-employment-arbitration. If you are unable to access these rules, inform the Company’s Human Resources Department and a hardcopy will be provided to you. As in any arbitration, the burden of proof shall be allocated as provided by applicable law. The arbitrator shall issue a written decision that contains the essential findings and conclusions on which the decision is based. The arbitrator shall have the same authority as a court to award equitable relief, damages, costs, and fees (excluding the costs and fees of the arbitrator) as provided by law for the particular claims asserted. This arbitration clause shall be governed by and construed in all respects under the terms of the Federal Arbitration Act and the California Arbitration Act, including Cal. Civ. Proc. Code § 1283.05.

You acknowledge that neither the Company nor its agents have made any promise, representation or warranty whatsoever, either express or implied, written or oral, which is not contained in this agreement for the purpose of inducing you to execute the agreement, and you acknowledge that you have executed this agreement in reliance only upon such promises, representations and warranties as are contained herein.

16.Severability. If any term of this letter is held to be invalid, void, or unenforceable, the remainder of the terms herein will remain in full force and effect and will in no way be affected, and the parties will use their best efforts to find an alternative way to achieve the same result.

17.Governing Law. The terms of this letter and the resolution of any dispute as to the meaning, effect, performance or validity of this letter or arising out of, related to, or in any way connected with this letter, your employment with the Company or any other relationship between you and the Company (a “Dispute”) will be governed by the laws of the State of Washington, without giving effect to the principles of conflict of laws.
