Pursuant to Section 5(c) of the Employment Agreement, Executive will be eligible to receive accelerated vesting of the PSU with respect to the target level of 375,000 shares. Executive’s continued group medical benefit under Section 5(a)(iii) of the Employment Agreement will be provided by the Company by means of additional taxable payments equal to the applicable COBRA premium.

7.Mutual Non-disparagement. The Parties acknowledge and agree that they will remain bound by Section 13 of the Employment Agreement with respect to obligations regarding non-disparagement. Nothing in this Agreement shall prevent either Executive or the Company employees who are aware of the existence of this Agreement from responding accurately and fully to any question, inquiry or request for information when required by legal process, nor prevent Executive from engaging in Protected Activity (as defined below).

8.Release of Claims. Executive agrees that the consideration to be paid in accordance with the terms of the Employment Agreement represents settlement in full of all outstanding obligations owed to Executive by the Company and its past, present and future officers, agents, directors, employees, investors, shareholders, administrators, affiliates, divisions, subsidiaries, parents, predecessor and successor corporations, and assigns (the “Releasees”). Executive, on behalf of himself, and his respective heirs, family members, executors and assigns, hereby fully and forever releases the Releasees from, and agrees not to sue or otherwise institute or cause to be instituted any legal or administrative proceedings concerning any claim, duty, obligation or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Executive may possess arising from any omissions, acts or facts that have occurred up until and including the Effective Date of this Agreement including, without limitation,

This release does not extend to any severance obligations due Executive under the Severance Agreement and does not release claims that cannot be released as a matter of law. Nothing in this Agreement waives Executive’s rights to indemnification or any payments under any insurance policy, if any, provided by any act or agreement of the Company, state or federal law or policy of insurance. Executive represents that Executive has made no assignment or transfer of any right, claim, complaint, charge, duty, obligation, demand, cause of action, or other matter waived or released by this Section.

9.Acknowledgment of Waiver of Claims under ADEA. Executive acknowledges that Executive is waiving and releasing any rights Executive may have under the Age Discrimination in Employment Act of 1967 (“ADEA”) and that this waiver and release is knowing and voluntary. Executive and the Company agree that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the Effective Date of this Agreement. Executive acknowledges that the consideration given for this waiver and release Agreement is in addition to anything of value to which Executive was already entitled. Executive further acknowledges that Executive has been advised by this writing that (a) Executive should consult with an attorney prior to executing this Agreement; (b) Executive has at least twenty-one (21) days within which to consider this Agreement; (c) Executive has seven (7) days following the execution of this Agreement by the parties to revoke the Agreement; (d) this Agreement shall not be effective until the revocation period has expired; and (e) nothing in this Agreement prevents or precludes Executive from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any

condition precedent, penalties or costs for doing so, unless specifically authorized by federal law. Any revocation should be in writing and delivered to the General Counsel at the Company by close of business on the seventh day from the date that Executive signs this Agreement. In the event Executive signs this Agreement and returns it to the Company in less than the 21-day period identified above, Executive hereby acknowledges that Executive has freely and voluntarily chosen to waive the time period allotted for considering this Agreement. The parties agree that changes, whether material or immaterial, do not restart the running of the 21-day period.

10.California Civil Code Section 1542. Executive acknowledges that Executive has been advised to consult with legal counsel and is familiar with the provisions of California Civil Code Section 1542, a statute that otherwise prohibits the release of unknown claims, which provides as follows:

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.

Executive, being aware of said code section, agrees to expressly waive any rights Executive may have thereunder, as well as under any other statute or common law principles of similar effect.

11.No Pending or Future Lawsuits. Executive represents that Executive has no lawsuits, claims, or actions pending in Executive’s name, or on behalf of any other person or entity, against the Company or any other person or entity referred to herein. Executive also represents that Executive does not intend to bring any claims on Executive’s own behalf or on behalf of any other person or entity against the Company or any other person or entity referred to herein.

12.No Cooperation. Subject to Section 14, Executive agrees that he or she will not counsel or assist any attorneys or their clients in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints by any third party against the Company and/or any officer, director, employee, agent, representative, shareholder or attorney of the Company, unless under a subpoena or other court order to do so or as related directly to the ADEA waiver in this Agreement. Executive agrees both to immediately notify the Company upon receipt of any such subpoena or court order, and to furnish, within three (3) business days of its receipt, a copy of such subpoena or other court order.

13.No Admission of Liability. Executive understands and acknowledges that this Agreement constitutes a compromise and settlement of disputed claims. No action taken by the Company, either previously or in connection with this Agreement shall be deemed or construed to be (a) an admission of the truth or falsity of any claims heretofore made or (b) an acknowledgment or admission by the Company of any fault or liability whatsoever to the Executive or to any third party.

14.Protected Activity. Executive understands that nothing in this Agreement or in the Confidentiality Agreement shall in any way limit or prohibit Executive from engaging for a lawful purpose in any Protected Activity. For purposes of this Agreement, “Protected Activity” shall mean filing a charge, complaint or report with, or otherwise communicating with, cooperating with or participating in any investigation or proceeding that may be conducted by any federal, state or local

government agency or commission, including the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”). Executive understands that in connection with such Protected Activity, Executive is permitted to disclose documents or other information as permitted by law, and without giving notice to, or receiving authorization from, the Company. Executive agrees to take all reasonable precautions to prevent any unauthorized use or disclosure of any information that may constitute Company Proprietary Information under this Agreement or the Confidentiality Agreement to any parties other than the relevant Government Agencies. Executive further understands that Protected Activity does not include the disclosure of any Company attorney-client privileged communications.

15.Tax Consequences. The Company makes no representations or warranties with respect to the tax consequences of the payments and any other consideration provided to Executive or made on Executive’s behalf under the terms of this Agreement. Executive agrees and understands that Executive is responsible for payment, if any, of local, state, and/or federal taxes on the payments and any other consideration provided hereunder by the Company and any penalties or assessments thereon. Executive further agrees to indemnify and hold the Releasees harmless from any claims, demands, deficiencies, penalties, interest, assessments, executions, judgments, or recoveries by any government agency against the Company for any amounts claimed due on account of (a) Executive’s failure to pay or delayed payment of federal or state taxes, or (b) damages sustained by the Company by reason of any such claims, including attorneys’ fees and costs.

16.Section 409A. It is intended that this Agreement comply with, or be exempt from, Internal Revenue Code Section 409A and the final regulations and official guidance thereunder (“Section 409A”) and any ambiguities herein will be interpreted to so comply and/or be exempt from Section 409A. The Company and Executive will work together in good faith to consider either (i) amendments to this Agreement; or (ii) revisions to this Agreement with respect to the payment of any awards, which are necessary or appropriate to avoid imposition of any additional tax or income recognition prior to the actual payment to Executive under Section 409A. In no event will the Releasees reimburse Executive for any taxes that may be imposed on Executive as a result of Section 409A.
