Nothing in this Release shall restrict
or prohibit the Executive or the Executives counsel from filing a charge or complaint with, initiating communications directly with, responding to any inquiry from, volunteering information to, or providing testimony before a self-regulatory
authority or a governmental, law enforcement or other regulatory authority, including the U.S. Equal Employment Opportunity Commission, the Department of Labor, the National Labor Relations Board, the Department of Justice, the Securities and
Exchange Commission, the Financial Industry Regulatory Authority, the Congress, and any Office of Inspector General (collectively, the Regulators), from participating in any reporting of, investigation into, or proceeding
regarding suspected violations of law, or from making other disclosures that are protected under or from receiving an award for information provided under the whistleblower award programs administered by a state or federal agency. The Executive does
not need the prior authorization of the Company or the Bank to engage in such communications with the Regulators, respond to such inquiries from the Regulators, provide confidential information or documents containing confidential information to the
Regulators, or make any such reports or disclosures to the Regulators. The Executive is not required to notify the Company or the Bank that the Executive has engaged in such communications with the Regulators. The Executive recognizes and agrees
that, in connection with any such activity outlined above, the Executive must inform the Regulators that the information the Executive is providing is confidential. To the extent, that any such charge or complaint is made against the Releasees, the
Executive expressly waives any claim or right to any form of monetary relief or other damages, or any form of individual recovery or relief in connection with any such charge or complaint, except that the Executive does not waive his right with
respect to any government-issued award for information provided under the whistleblower award programs administered by a state or federal agency.
