Effective July 28, 2023, Boston Properties, Inc.?s independent directors appointed Joel I. Klein to serve as the lead independent director, replacing Kelly A. Ayotte.

Ms. Ayotte served as BXP?s lead independent director since May 2022 and will remain on BXP?s Board of Directors.

Mr. Klein previously served as BXP?s lead independent director from May 2016 to May 2019 and as its independent Chairman from May 2019 to May 2022.
