These forward-looking statements are subject to the principal risks and uncertainties applicable to the respective businesses of PNC and Sterling generally that are disclosed in the 2006 Form 10-K and in current year Form 10-Qs and 8-Ks of PNC and Sterling (accessible on the SEC’s Web site at www.sec.gov and on PNC’s Web site at www.pnc.com and on Sterling’s Web site at www.sterlingfi.com, respectively). In addition, forward-looking statements in this press release are subject to the following risks and uncertainties related both to the acquisition transaction itself and to the integration of the acquired business into PNC after closing:

 

   

Completion of the transaction is dependent on, among other things, receipt of regulatory and shareholder approvals, the timing of which cannot be predicted with precision at this point and which may not be received at all. The impact of the completion of the transaction on PNC’s financial statements will be affected by the timing of the transaction.

 

   

The transaction may be substantially more expensive to complete (including the integration of Sterling’s businesses) and the anticipated benefits, including anticipated cost savings and strategic gains, may be significantly harder or take longer to achieve than expected or may not be achieved in their entirety as a result of unexpected factors or events.

 

   

The integration of Sterling’s business and operations into PNC, which will include conversion of Sterling’s different systems and procedures, may take longer than anticipated or be more costly than anticipated or have unanticipated adverse results relating to Sterling’s or PNC’s existing businesses.

 

   

The anticipated benefits to PNC are dependent in part on Sterling’s business performance in the future, and there can be no assurance as to actual future results, which could be impacted by various factors, including the risks and uncertainties generally related to PNC’s and Sterling’s performance or due to factors related to the acquisition of Sterling and the process of integrating it into PNC.
