[9] The company Autonomy etalk planned to move its employees to the Chase Tower from Las Colinas, Irving in 2008.

[11] In 2015 and 2016 renovations were made to many of the common areas including the main lobby and mezzanine level of the building.

Lighting and furniture upgrades were included along with a remodel of the existing sundries shop and Starbucks coffee kiosk.

The rotunda which sits on the property's north plaza was remodeled as a fitness center exclusive to Chase Tower tenants.

It includes cardio, free weight and circuit training equipment as well as a studio center for group fitness and spinning class workouts.

The 40th floor Sky Lobby at the base of the "keyhole" contained a little-known observation area which is no longer available to the public.
