Ms. King served as Chief Financial Officer of Tmunity Therapeutics, Inc., a biotherapeutics company, from September 2020 to June 2021. Prior to that, Ms. King served as Vice President of Financial Planning and Analysis and Assistant Treasurer at Emergent BioSolutions, a biopharmaceutical company, from July 2019 to September 2020. From September 2000 to April 2019, Ms. King held various positions at Bristol Meyers Squibb, including Executive Director of Corporate Financial Planning and Analysis and Executive Director of Enterprise Services. Ms. King is a certified public accountant. Ms. King received her B.A. in Economics at Kalamazoo College and her M.B.A. in Finance from Columbia Business School. She also attended the University of Cape Town as a Rotary Ambassadorial Scholar, where she received a diploma in African Studies.
Pursuant to her employment agreement, Ms. King will (i) receive an annual base salary of $425,000 and (ii) be eligible to receive a cash bonus of up to 40% of her annual base salary, subject to the achievement of certain performance criteria. Ms. King will also receive a stock option to purchase 360,000 shares of common stock at an exercise price equal to the closing sale price of the common stock on the date of grant, as reported by the Nasdaq Global Select Market, which will vest as to 1/4th of the shares on the date that is one year following the Commencement Date and 1/48th of the shares monthly thereafter until fully vested, subject to her continued service to the Company.
Additionally, pursuant to Ms. King's employment agreement, if she is terminated without "cause" or resigns for "good reason" (as such terms are defined in her employment agreement), and subject to her execution and non-revocation of a release of claims, she will be entitled to (i) a lump-sum payment equal to nine months of her base salary if such termination occurs in the first year of employment or 12 months of her base salary if such termination occurs thereafter, and (ii) a taxable lump-sum payment equal to 12 months of COBRA premiums she would be required to pay to maintain group healthcare coverage as in effect on the date of termination. In the event that a successor company does not assume or substitute the equity awards held by Ms. King in connection with a "change in control", or if she is terminated without "cause" or resigns for "good reason" within two months prior to, or 12 months following, a "change in control" (as such terms are defined in their respective employment agreements), then, in addition to the severance noted above, she will receive 100% of her then current target bonus, payable in a lump sum and her then outstanding unvested options and other equity awards will become fully vested and exercisable, as applicable, and any forfeiture restrictions thereon will lapse. Unless otherwise set forth in an applicable grant agreement, any performance conditions applicable to such equity awards will be deemed achieved at the greater of target or actual performance.
Prior to the Commencement Date, the Company will enter into its standard form of indemnification agreement with Ms. King. The form of the indemnification agreement was previously filed by the Company as Exhibit 10.1 to the Company's Registration Statement on Form S-1 filed with the Securities and Exchange Commission (the "Commission") on February 3, 2020 and incorporated by reference herein.
There are no arrangements or understandings between Ms. King and any other persons, pursuant to which she was appointed as Chief Financial Officer. There are also no family relationships between Ms. King and any director or executive officer of the Company, nor does Ms. King have a direct or indirect material interest in any transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K.

On July 15, 2021, the Board appointed Bruce Goldsmith, Ph.D., a member of the Board and the Company's President and Chief Executive Officer, as the Company's Principal Financial Officer, effective immediately until the Commencement Date, at which point Ms. King will serve as the Company's Principal Financial Officer and Principal Accounting Officer until the earlier of her resignation, death or removal from office.
