For each transaction listed thereon, Schedule I hereto identifies the Reporting Period for such transaction.

List of exemptions for BANK 2021-BNK37 Commercial Mortgage Pass-Through Certificates Series 2021- BNK37:

Computershare Trust Company, N.A. made the April 18, 2022 distribution (the "April Distribution") due to certificate holders of the BANK 2021-BNK37 Commercial Mortgage Pass-Through Certificates Series 2021- BNK37 transaction one business day late on April 19, 2022. The inadvertent delay in the required distribution, consisting of approximately $3.80 million, was caused by an administrative error relating to the calculation of the payment date in an internal system due to Good Friday. The error resulted in a delay in the release of the payment information to the payment processing system, which in turned caused the late distribution. The impact of this error was limited to the April Distribution. In an effort to prevent similar errors from occurring, Computershare Trust Company, N.A. has updated the payment date calculation process in its systems.
