Mr. Iwicki will continue to serve as a member of the Board. In connection with his appointment as chairman. On April 22, 2020, the Board completed a process to reassign the class of a member of the Board so that each class would have an equal size. Solely to effect this change, Richard Batycky, Ph.D. resigned as a Class I director of the Company, effective as of April 22, 2020, and was immediately reappointed by the Board as a Class II director of the Company by the remaining members of the Board, to serve in such capacity until the next annual meeting of stockholders at which the term of the Class II directors expires or until his successor is duly elected and qualified, or his earlier death, resignation or removal. As Dr. Batycky’s resignation and reappointment were effected solely to maintain the size of each class as nearly equal in number as possible, his service on the Board is deemed to have continued uninterrupted without any break in service. Dr. Batycky will continue to serve on the Board’s Audit and Compensation Committees.
