                     THE PNC FINANCIAL SERVICES GROUP, INC.
                          ANNOUNCES THE ACQUISITION OF
                            UNITED NATIONAL BANCORP



                                AUGUST 21, 2003



FORWARD-LOOKING INFORMATION
--------------------------------------------------------------------------------

This presentation contains forward-looking statements with respect to PNC's
outlook or expectations with respect to the Planned acquisition of United
National, the expected costs to be incurred in connection with the acquisition,
United National's future performance, and the consequences of the integration of
United National into PNC. Forward-looking statements are subject to numerous
assumptions, risks and uncertainties, which change over time. The
forward-looking statements in this presentation speak only as of the date of
this presentation, and PNC assumes no duty and does not undertake to update
them.

In addition to factors previously disclosed in PNC's SEC reports (accessible on
the SEC's website at www.sec.gov and on PNC's website at www.pnc.com) applicable
to PNC's business generally (including, upon the acquisition, those aspects
currently operated by United National), the forward-looking statements in this
presentation are subject to the following risks and uncertainties:

^         Completion of the transaction is dependent on, among other things,
          receipt of stockholder and regulatory approvals, the timing of which
          cannot be predicted with precision at this point and which may not be
          received at all.

^         The transaction may be materially more expensive to complete than
          anticipated, as a result of unexpected factors or events.

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

^         The anticipated cost savings of the acquisition may take longer to be
          realized or may not be achieved in their entirety.

^         The anticipated benefits to PNC are dependent in part on United
          National'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 United National's performance (with respect to
          United National, see United National's SEC reports, also accessible on
          the SEC's website) or due to factors related to the acquisition of
          United National and the process of integrating it into PNC.
