payment of $77,778.00, less all appropriate federal and state income and employment taxes (“Severance Payment”). The Severance Payment will be made in a lump sum cash payment on the Separation Date, by wire transfer to a bank account

 1.3
Resignation. Company agrees to characterize Executive’s separation as a voluntary resignation in any public statement or request for reference. Notwithstanding the foregoing, the Company shall be permitted to file this Agreement with the

Executive unconditionally, irrevocably and absolutely releases and discharges Company, and any parent and subsidiary corporations, divisions and affiliated corporations, partnerships or other affiliated entities of Company, past and present, as well
as their Executives, officers, directors, agents, successors and assigns (collectively, “Released Parties”), from all claims related in any way to the transactions or occurrences between them to date, to the fullest extent permitted by
law, including, but not limited to, Executive’s employment with Company, the termination of Executive’s employment, and all other losses, liabilities, claims, charges, demands and causes of action, known or unknown, suspected or
unsuspected, arising directly or indirectly out of or in any way connected with Executive’s employment with Company. This release is intended to have the broadest possible application and includes, but is not limited to, any tort, contract,

Employment and Housing Act, the Americans with Disabilities Act, the Age Discrimination in Employment Act of 1967, as amended (“ADEA”), and all claims for attorneys’ fees, costs and expenses. However, this general release is not
intended to bar any claims that, by law, may not be waived, such as claims for workers’ compensation benefits, unemployment insurance benefits, statutory indemnity, and any challenge to the validity of Executive’s release of claims under
the ADEA (“ADEA Claims”), as set forth in this Separation Agreement. 
 4.2 Executive acknowledges that Executive may discover
facts or law different from, or in addition to, the facts or law that Executive knows or believes to be true with respect to the claims released in this Separation Agreement and agrees, nonetheless, that this Separation Agreement and the release

Commission or similar state or local administrative agency, Executive expressly waives Executive’s right to recovery of any type, including damages or reinstatement, in any administrative or court action, whether state or federal, and whether
brought by Executive or on Executive’s behalf, related in any way to the matters released herein. 
 5. California Civil Code
Section 1542 Waiver. Executive expressly acknowledges and agrees that all rights under Section 1542 of the California Civil Code are expressly waived. That section provides: 

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE
RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.

plan or practice. 
 11. No Admissions. By entering into this Separation Agreement, the Released Parties make no admission that
they have engaged, or are now engaging, in any unlawful conduct. The parties understand and acknowledge that this Separation Agreement is not an admission of liability and shall not be used or construed as such in any legal or administrative

paragraph 12.1 above. 
 12.3 Revocation/Effective Dates. With respect to all claims released by this Separation Agreement,
except the waiver of the ADEA claims, this Separation Agreement shall become effective and enforceable on the day it is signed by Executive. Executive’s waiver of the ADEA Claims will become effective and enforceable on the eighth day
after Executive signs this Separation Agreement. In other words, Executive may revoke Executive’s acceptance of this Separation Agreement as to the ADEA Claims within seven (7) days after the date Executive signs it. Executive’s
revocation must be in writing and received by the Chairman of the Board by 5:00 p.m. Pacific Time on the seventh day in order to be effective. If Executive timely revokes, Executive’s ADEA Claims will survive the signing of this Separation
