Explanation of Responses:
(1)	In connection with the vesting on January 11, 2022 of restricted stock units previously granted to the reporting person, the reporting person's receipt of 2,252.2426 shares of common stock was deferred, resulting in the reporting person's receipt instead of 2,252.2426 shares of phantom stock pursuant to BOKF's deferred compensation plan. The reporting person is therefore reporting the disposition of 2,252.2426 shares of common stock in exchange for an equal number of shares of phantom stock.
(2)	Each share of phantom stock represents a right to receive one share of common stock or, at BOKF's election, the cash value thereof.
(3)	The phantom stock becomes payable upon the reporting person's termination of employment with BOKF.
