EX-97.1

1.1.

The Board has determined that it is in the best interests of the Company and its stockholders to adopt this Policy enabling the Company to recover from specified current and former Company executives certain incentive-based compensation in the event of an accounting restatement due to material noncompliance with any financial reporting requirements under the federal securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. Capitalized terms are defined in Section 15.

2.1.

This Policy shall be administered by the Administrator. The Administrator is authorized to interpret and construe this Policy and to make all determinations necessary, appropriate, or advisable for the administration of this Policy. The Administrator may retain, at the Company’s expense, outside legal counsel and such compensation, tax or other consultants as it may determine are advisable for purposes of administering this Policy.

3.1.

This Policy applies to any Incentive-Based Compensation Received by a person (a) after the Listing Rule Effective Date, (b) after beginning service as a Covered Person; (c) who served as a Covered Person at any time during the

4.1.

Subject to and in accordance with the provisions of this Policy, if there is a Triggering Event, the Administrator shall take steps to require a Covered Person to reimburse or forfeit to the Company the Recoupment Amount applicable to such Covered Person. The Company’s obligation to recover the

6.1.

Subject to compliance with the Rules and applicable law, the Administrator will determine, in its sole discretion, the method for recouping the Recoupment Amount hereunder which may include, without limitation:

6.1.2.

Offsetting the Recoupment Amount from any compensation otherwise owed by the Company to the Covered Person, including without limitation, any unpaid cash incentive payments, executive retirement benefits, wages, equity grants or other amounts payable by the Company to the Covered Person in the future;

7.1.

To the fullest extent permitted by law, any disputes under this Policy shall be submitted to mandatory binding arbitration (the “Arbitrable Claims”), governed by the Federal Arbitration Act (the “FAA”). Further, to the fullest extent permitted by law, no class or collective actions can be asserted in arbitration or otherwise. All claims, whether in arbitration or otherwise, must be brought solely in the Covered Person’s individual capacity, and not as a plaintiff or class member in any purported class or collective proceeding.

7.2.

SUBJECT TO THE ABOVE PROVISO, ANY RIGHTS THAT A COVERED PERSON MAY HAVE TO TRIAL BY JURY IN REGARD TO ARBITRABLE CLAIMS ARE WAIVED. ANY RIGHTS THAT A COVERED PERSON MAY HAVE TO PURSUE OR PARTICIPATE IN A CLASS OR COLLECTIVE ACTION PERTAINING TO ANY CLAIMS BETWEEN A COVERED PERSON AND THE COMPANY ARE WAIVED.

7.3.

The Covered Person is not restricted from filing administrative claims that may be brought before any government agency where, as a matter of law, the Covered Person’s ability to file such claims may not be restricted. However, to the fullest extent permitted by law, arbitration shall be the exclusive remedy for the subject matter of such administrative claims. The arbitration shall be conducted in Alameda County, California, through JAMS before a single neutral arbitrator, in accordance with the JAMS Comprehensive Arbitration Rules and Procedures then in effect, provided however, that the FAA, including its procedural provisions for compelling arbitration, shall govern and apply to this Arbitration provision. The arbitrator shall issue a written decision that contains the essential findings and conclusions on which the decision is based. If, for any reason, any term of this Arbitration provision is held to be

8.2.

The Administrator must cause the Company to recover the Recoupment Amount unless the Administrator shall have previously determined that recovery is impracticable and one of the following conditions is met:

8.2.1.

The direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered; before concluding that it would be impracticable to recover any Recoupment Amount based on expense of enforcement, the Company must make a reasonable attempt to recover such Recoupment Amount, document such reasonable attempt(s) to recover, and provide that documentation to the Exchange;

8.2.2.

Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

9.1.

The Administrator intends that this Policy will be applied to the fullest extent of the law. Without limitation to any broader or alternate clawback authorized in any written document with a Covered Person, (i) the Administrator may require that any employment agreement, equity award agreement, or similar agreement entered into on or after the Effective Date shall, as a condition to

the grant of any benefit thereunder, require a Covered Person to agree to abide by the terms of this Policy, and (ii) this Policy will nonetheless apply to Incentive-Based Compensation as required by the Rules, whether or not specifically referenced in those arrangements and regardless of whether a Covered Person agreed in writing to adhere to this Policy. Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies or rights of recoupment that may be available to the Company pursuant to the terms of any other clawback policy of the Company as then in effect, or any similar policy in any employment agreement, equity award agreement, or similar agreement and any other legal remedies or regulations available or applicable to the Company (including SOX 304). If recovery is required under both SOX 304 and this Policy, any amounts recovered pursuant to SOX 304 may, in the Administrator’s discretion, be credited toward the amount recovered under this Policy, or vice versa.

10.1.

The Company shall not indemnify any Covered Persons against (i) the loss of any Recoupment Amount or any adverse tax consequences associated with any Recoupment Amount or any recoupment hereunder, or (ii) any claims relating to the Company enforcement of its rights under this Policy. For the avoidance of doubt, this prohibition on indemnification will also prohibit the Company from reimbursing or paying any premium or payment of any third-party insurance policy to fund potential recovery obligations obtained by the Covered Person directly. No Covered Person will seek or retain any such prohibited indemnification or reimbursement.

10.2.

Further, the Company shall not enter into any agreement that exempts any Incentive-Based Compensation from the application of this Policy or that waives the Company’s right to recovery of any Recoupment Amount and this Policy shall supersede any such agreement (whether entered into before, on or after the Effective Date).

11.1.

All Covered Persons subject to this Policy must acknowledge their understanding of, and agreement to comply with, the Policy by executing the acknowledgement in the form attached hereto as Exhibit A, as may be amended. Notwithstanding the foregoing, this Policy will apply to

12.1.

This Policy shall be binding and enforceable against all Covered Persons and their beneficiaries, heirs, executors, administrators or other legal representatives and shall inure to the benefit of any successor to the Company.

13.1.

To the extent there is any ambiguity between this Policy and the Rules, this Policy shall be interpreted so that it complies with the Rules. If any provision of this Policy, or the application of such provision to any Covered Person or circumstance, shall be held invalid, the remainder of this Policy, or the application of such provision to Covered Persons or circumstances other than those as to which it is held invalid, shall not be affected thereby.

13.2.

In the event any provision of this Policy is inconsistent with any requirement of any Rules, the Administrator, in its sole discretion, shall amend and administer this Policy and bring it into compliance with such rules.
