In the event of a POWER OUTAGE, Hamilton Partners will:

1. Contact Com Ed and inform tenants of details surrounding the power outage (i.e., time of outage, estimated time when power will be restored, cause of power outage if known.)
2. Evacuate all elevators and direct all traffic to stairwells.

In the event of a MAJOR POWER FAILURE (a total power failure on an entire floor or a series of floors,) we ask that all tenants:

1. Remain Calm.
2. If possible, notify the Management Office at 630-250-9700 and provide the following information:
   • Your company, name and business telephone number
   • Floor number(s) where power failure has occurred
   • Details of power failure
