On March 11, 2021, the Board of Directors of the Company appointed Prathyusha Duraibabu as the Company’s principal financial officer with immediate effect. Ms. Duraibabu has served as the Company’s principal accounting officer since June 2019 and as the Company’s Vice President, Finance since March 2019.

Ms. Duraibabu, age 42, has over 22 years of experience in optimizing financial operations, driving organizational change, building diverse teams and delivering results. Prior to joining the Company, Ms. Duraibabu served as Corporate Controller at Pacific Biosciences of California, Inc., a publicly-traded commercial biotechnology company, from June 2010 to March 2019. At Pacific Biosciences, she was responsible for global financial operations, strategy, audit and tax. Ms. Duraibabu received a Bachelors of Accounting from Oxford Brookes University in Oxford, United Kingdom and an M.B.A. from San Jose State University. Ms. Duraibabu is a Certified Public Accountant in the State of California.

On or about May 24, 2021, the Compensation Committee of the Company’s Board of Directors approved the promotion of Ms. Duraibabu to Senior Vice President and Chief Financial Officer and a new compensation package for Ms. Duraibabu, consisting of an annual base salary of $400,000, a target cash bonus of 35% of her annual base salary under the Company’s Amended and Restated Incentive Compensation Plan (the “Bonus Plan”), a stock option award to purchase 15,000 shares of the Company’s common stock (the “Option Award”), a restricted stock unit award covering 7,500 shares of the Company’s common stock (the “RSU Award”), and Ms. Duraibabu’s participation in the Company’s Amended and Restated Executive Severance Plan (the “Severance Plan”) at the level set forth in such plan for Senior Vice Presidents. This promotion is effective June 1, 2021. The Option Award will be subject to a four-year vesting schedule with 25% of the shares subject to the Option Award vesting upon Ms. Duraibabu’s completion of one year of service measured from the grant date and the balance of the shares vesting monthly thereafter for the next three years. The RSU Award will vest in a series of three successive equal installments upon completion of each year of service measured from the grant date. The Option Award and the RSU Award will be granted under the Company’s Amended and Restated 2018 Equity Incentive Plan (the “EIP”), and Ms. Duraibabu will continue to be eligible for future equity awards under such plan on an annual basis.
