EXPIRING LOCK-UP RESTRICTIONS Certain of the outstanding shares of Brooklyn common stock are subject to a lock-up restriction that continues until September 21, 2021. If you hold shares represented by a physical certificate that bears a legend with respect to this lock-up restriction, Computershare has been instructed to no longer give effect to that lock-up legend, effective as of September 21, 2021. If you hold book-entry shares that are subject to this lock-up restriction, Computershare will remove the related electronic lock-up legend automatically, effective as of September 21, 2021. If your shares are subject to other transfer restrictions, those restrictions will remain effective in accordance with the applicable contractual or regulatory requirements.
OUTSTANDING CHECKS We encourage you to cash any outstanding checks issued by the previous transfer agent that you have in your possession as soon as practicable, in order to ensure that you will be able to cash any checks previously issued by the previous agent and will not need to contact Computershare for replacement checks.
We appreciate your investment in Brooklyn.
