Item 1.01.   ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

      On February 10, 2005, The PNC Financial Services Group, Inc. ("PNC") and
Riggs National Corporation ("Riggs") amended and restated the Agreement and
Plan of Merger, dated July 16, 2004, between PNC and Riggs.  A copy of the
Amended and Restated Agreement and Plan of Merger is attached hereto as
Exhibit 2.1.

      The Amended and Restated Agreement and Plan of Merger, which is
substantially similar to the original agreement, values each share of Riggs
common stock at approximately $20.00 based on PNC's closing NYSE stock price
of $54.58 on February 7, 2005.  The aggregate consideration is composed of a
fixed number of approximately 6.4 million shares of PNC common stock and $286
million in cash in exchange for all 31.8 million Riggs common shares
outstanding, subject to adjustment.  Riggs stock options, currently with an
aggregate in-the-money value of approximately $16 million, will be cashed out
prior to closing, if not exercised.

      The transaction is expected to close as soon as possible, and either
party may terminate the agreement after May 31, 2005 if the transaction has
not closed. The merger remains subject to customary closing conditions,
including regulatory approvals, the approval of Riggs shareholders, and the
receipt of exemptions from the Department of Labor and the SEC to mitigate
the potential business impact of Riggs Bank's plea agreement with the
Department of Justice.  The exemption sought from the Department of Labor
would allow Riggs and PNC to retain "qualified professional asset manager"
status. The exemption sought from the Securities and Exchange Commission
would allow PNC to continue to advise registered mutual funds under Section 9
of the Investment Company Act of 1940, notwithstanding Riggs Bank's guilty
plea with the Department of Justice.  Mr. Joe L. Allbritton's agreement to
vote 24.6% of the outstanding shares of Riggs in favor of the transaction
remains applicable.

      A press release regarding the foregoing is attached hereto as Exhibit
99.1.
