On August 17, 2023, Laurie Stelzer notified Mirati Therapeutics, Inc. (the “Company”) of her intention to resign from her position as the Company’s Chief Financial Officer and principal financial and accounting officer, effective as of September 8, 2023 (the “Separation Date”), in order to pursue an opportunity with another biotechnology company.

Ms. Stelzer has agreed to provide transition consulting services (the “Consulting Services”) to the Company for an initial term of 60 days following the Separation Date. As consideration for providing the Consulting Services, the Company will pay Ms. Stelzer $10,000 per month and her outstanding equity awards will continue to vest pursuant to their terms.

On August 21, 2023, the Board of Directors of the Company (the “Board”) appointed Aaron Ondrey, the Company’s Senior Vice President, Financial Planning and Analysis, as the Company’s Interim Chief Financial Officer and principal financial officer, effective as of the Separation Date.

Mr. Ondrey, age 47, has served as the Company’s Senior Vice President, Financial Planning and Analysis since July 2022. Prior to joining the Company Mr. Ondrey served as Vice President, Finance of Arena Pharmaceuticals, Inc., a public biotechnology company (acquired by Pfizer Inc. in March 2022) from January 2020 until July 2022. From December 2018 to January 2020, Mr. Ondrey served as Head of Global Commercial Finance at Alexion Pharmaceuticals, Inc., a public biotechnology company (acquired by AstraZeneca in July 2021).

The Retention Award will vest and be payable in full on the date that is 90 calendar days following the date that a permanent Chief Financial Officer commences employment with the Company (the “Vesting Date”), subject to Mr. Ondrey’s continuous service through such date. The Retention Award will vest and be payable in full if Mr. Ondrey’s employment with the Company is terminated without Cause (as defined under the Company 2022 Equity Incentive Plan) prior to the Vesting Date. Mr. Ondrey’s employment is at-will and may be terminated at any time by either Mr. Ondrey or by us with or without Cause and without notice.
