The Independent Contractor further agrees that all works of authorship which are made by or on behalf of the Independent Contractor (solely or jointly with others) in the course of performance of Services under this Agreement and which are protectable by copyright are “works made for hire,” as that term is defined in the 1976 Copyright Act as amended (title 17 of the United States Code) (“Works of Authorship”; and together with Inventions, “Work Product”).

The Independent Contractor further agrees to cooperate to the extent and in the manner requested by the Company in the prosecution or defense of any such patent or copyright or other intellectual property claims or any litigation or other proceeding involving any Work Product in any country of the world, but all time and documented expenses thereof shall be paid by the Company. The foregoing covenant and the rights of the Company under this Section 4 include, without limitation, any improvements of

properties, rights, systems, inventions, works of authorship and the like presently held by the Company or any affiliate thereof.

The Independent Contractor represents and warrants that the Independent Contractor has the right and unrestricted ability to enter this Agreement and to perform all of its obligations contained herein. Without limiting the foregoing, the Independent Contractor represents and warrants that it has the right to assign the entire right, title and interest in and to the Work Product to the Company pursuant to Section 4.

6. NO DEBARMENT.

The Independent Contractor represents and warrants that neither Independent Contractor nor any of its employees nor any other person engaged by it to perform the Services:

7. INDEPENDENT CONTRACTOR RELATIONSHIP.

The Independent Contractor’s relationship with the Company is that of an independent contractor, and nothing in this Agreement is intended to, or should be construed to, create a partnership, agency, joint venture or employment relationship. The Independent Contractor shall not be entitled to any of the benefits that the Company may make available to its employees, including, but not limited to, group health (medical, dental, vision), life and disability insurance (including IDI), hospital indemnity, profit sharing, or retirement benefits. The Independent Contractor is not authorized to make any representation, contract, or commitment on behalf of the Company unless specifically requested or authorized in writing to do so by an executive officer of the

A. If the Independent Contractor timely and properly elects health continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA"), the Company shall cover the full COBRA premium.

The Independent Contractor shall be eligible to receive such reimbursement until December 31, 2024. Notwithstanding the foregoing, if the Company's making payments would violate the nondiscrimination rules applicable to non-grandfathered plans under the Affordable Care Act (the "ACA") or result in the imposition of penalties under the ACA and the related regulations and guidance promulgated thereunder), the parties agree to reform this Section 8 in a manner as is necessary to comply with the ACA.

The Independent Contractor will not disclose to the Company, or induce the Company to use, any confidential or proprietary information or material belonging to any third party.

Nothing in this Agreement is intended, nor shall be construed, to prohibit Independent Contractor from any communications to, or participation in any investigation or proceeding conducted by any government agency, including but not limited to the Securities and Exchange Commission (SEC), Financial Industry Regulatory Authority (FINRA) or other self-regulatory or governmental agency with jurisdiction over the Company’s business, or otherwise interfere with, restrain, or prevent Independent Contractor from engaging in any legally protected activity, including legally protected whistleblowing activity. Moreover, Independent Contractor cannot be held criminally or civilly liable under any federal or state trade secret law if he discloses a trade secret (i) in confidence to federal, state, or local government officials, directly or indirectly, or to his attorneys, for the sole purpose of reporting or investigating a suspected violation of the law or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Additionally, if Independent Contractor files a lawsuit for retaliation by an employer for reporting a suspected violation of the law, Independent Contractor may disclose a trade secret to his attorney and use the trade secret information in that court proceeding provided that he (iii) files any document containing such trade secret under seal, and (iv) does not disclose any such trade secret, except pursuant to court order.
