NOTICE OF BLACKOUT PERIOD
As you know, you may not buy or sell PNC securities (including PNC common stock) during a specified period of time in each calendar quarter (the Quarterly Blackout Period). The next Quarterly Blackout Period will begin on Sunday, March 16, 2008 and will last until the second business day following the public release of PNCs first quarter 2008 earnings. You will be informed of the exact date on which the Quarterly Blackout Period will end.
Please note that the Quarterly Blackout Period is expected to overlap with but may not necessarily end at the same time as a separate blackout period for participants in the PNC Incentive Savings Plan and PFPC Retirement Savings Plan (collectively, the Benefit Plans). As explained in the attached notice for the PNC Incentive Savings Plan, the blackout period for the Benefit Plans is scheduled to begin on Thursday, April 3, 2008 at 4:00 p.m. Eastern Time, and end on Monday, April 21, 2008 at 9:00 a.m. Eastern Time (the Plan Blackout Period).
