Consultant will be solely responsible for all tax returns and payments required to be filed with or made to any federal, state or local tax authority with respect to Consultant’s performance of services and receipt of fees under this Agreement.

Consultant shall not assign this Agreement or its obligations hereunder without the prior written consent of Company and any such purported assignment shall be null and void.

This Agreement may not be waived, modified, amended or assigned unless mutually agreed upon in writing by both parties. In the event any provision of this Agreement is found to be legally unenforceable, such unenforceability shall not prevent enforcement of any other provision of the Agreement. The rights and obligations of the parties under this Agreement shall be governed in all respects by the laws of the State of California exclusively, as such laws apply to contracts between residents of the State of California performed entirely within California, without reference to conflict of laws principles. Consultant agrees that upon Company’s request, all disputes arising hereunder shall be adjudicated in the state and federal courts having jurisdiction over disputes arising in San Diego County, California, and Consultant hereby agrees to consent to the personal jurisdiction of such courts. Any notices required or permitted hereunder shall be given to the appropriate party at the address specified above or at such other address as the party shall specify in writing. Such notice shall be deemed given upon personal delivery, or sent by certified or registered mail, postage prepaid, three (3) days after the date of mailing.

Notwithstanding the foregoing, Consultant agrees to take all reasonable precautions to prevent any unauthorized use or disclosure of any information that may constitute Company confidential information to any parties or in any manner not protected by applicable law. Consultant further understands that “Protected Activity” does not include the disclosure of any Company attorney-client privileged communications. Pursuant to the Defend Trade Secrets Act of 2016, Consultant is notified that an individual will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made in confidence to a federal, state, or local government official (directly or indirectly) or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if (and only if) such filing is made under seal. In addition, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the individual’s attorney and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order.
