Decline of Security Deposit/Letter of Credit. Provided Tenant has satisfied the Financial Conditions (as defined in this Section 5.3) and no Event of Default exists under this Lease or would exist but for the pendency of any cure periods provided for in Section 20.1 herein (collectively, the “Reduction Conditions”), the Security Deposit, or Letter of Credit posted in lieu thereof, shall be reduced on the following dates (each a “Reduction Date”) as follows: # on May 1, 2023 (“First Reduction Date”), to ​ (“First Reduction Amount”); # on November 1, 2025 (“Second Reduction Date”), to ​ (“Second Reduction Amount”); and # on May 1, 2028 (“Third Reduction Date”), to ​.
