1. Employment; Location. Executive’s employment shall be at Executive’s current work location (as in effect as of the Effective Date) for the remainder of the Term.

2. Term. Unless earlier terminated pursuant to Section 7, Executive’s employment shall continue through December 31, 2025 (the term that Executive is employed hereunder is referred to as the “Term”), at which time Executive’s position shall be eliminated and treated as a termination by the Company at such time, in accordance with (and for purposes of severance with respect to) Section 7.2 and other applicable provisions of this Agreement. The parties may agree by mutual agreement to a Term beyond the date set forth above.

The Company may terminate Executive’s employment at any time for any reason (or no reason) as determined by the majority of all directors, and Executive may terminate Executive’s employment with the Company for Good Reason and resign any and all positions as officer of the Company and any related companies. If the Company terminates Executive’s employment or Executive terminates her employment for Good Reason or if Executive’s employment ends due to Executive’s death or disability, then so long as Executive (or, in the event of Executive’s death or disability, an authorized representative of Executive or Executive’s estate) executes and returns to the Company by the Release Expiration Date (and does not exercise any revocation right set forth within such release) a release of claims in the form set forth at Exhibit B (such release is referred to herein as the “Release”), then:

(e)II. There shall be added as to the Agreement the following provisions:

(f)Consulting Services. At the end of the Term of this Agreement, for Executive’s cooperation thereafter and any requested consulting, if and as requested by the Company, she shall do so at the rate of $450 per hour and subject to the terms of the Company’s standard form of consulting agreement.

(g)Definitions. As used herein, the term: (i) “Payment Date” means the Company’s first payroll date that comes after the date that Executive has timely returned the Release to the Company and any revocation date set forth in such Release has expired without Executive having exercised her revocation right; and “Release Expiration Date” means that date that is twenty-one (21) days following the date upon which Executive’s employment with the Company ends or, in the event that Executive’s termination of employment is “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), the date that is forty-five (45) days following such delivery date.

(h)Permitted Disclosures. Nothing herein or in any other agreement between Executive and the Company will prevent or limit Executive from (i) initiating communications directly with, cooperating with, providing information to, causing information to be provided to, or otherwise assisting in an investigation by, any governmental agency (including, for the avoidance of doubt, the Department of Justice, Department of Labor, Securities and Exchange Commission, any Inspector General, and any other governmental agency, commission or regulatory authority) regarding a possible violation of any law; (ii) responding to any inquiry or legal process directed to Executive from any governmental agency; (iii) testifying, participating or otherwise assisting in any action or proceeding by any governmental agency relating to a possible violation of law; or (iv) making any other disclosures that are protected under the whistleblower provisions of any applicable law.

III. For the avoidance of doubt, Sections 7.2(b) (and those paragraphs of Section 7.2 of the Employment Agreement that follow Section 7.2(b)), 7.3 and 7.4 of the Employment Agreement shall remain intact and unchanged following the Parties’ entry into this Agreement, notwithstanding the changes to Sections 7.2 and 7.2(a) of the Employment Agreement as reflected above.

IV. The Company acknowledges and agrees that Executive is in good standing with the Company. This Agreement constitutes the full and complete understanding and agreement of the parties hereto with respect to the application of the provisions of the Employment Agreement covered herein following the Effective Date, and supersedes all prior oral or written understandings and agreements with respect to such specific subject matter, other than the Change in Control Agreements. This Amendment may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same agreement. Counterparts and signatures transmitted by facsimile shall be valid, effective and enforceable as originals.
