3. Effective June 30, 2004, all accruals under the Plan for employees of PFPC Worldwide, Inc. and its participating subsidiaries shall cease. The Plan Manager, in the exercise of his duties, shall cause all Participant Accounts for Participants who are employees of PFPC Worldwide, Inc. and its participating subsidiaries to be valued as of the close of business on June 30, 2004 and shall thereafter direct the Trustee to transfer such Participants’ Accounts (including participant loans) to the Trustee of the trust established to hold assets of The PFPC Inc.

4. The Corporation intends by this Sixth Amendment to cease participation and accruals and to provide for the transfer of Account balances for eligible employees of PFPC Worldwide, Inc. and its participating subsidiaries, effective July 1, 2004, so that such employees will commence participation in the RSP effective July 1, 2004. To the extent that pertinent provisions of the Plan later require conforming changes to embody such intent, the Plan is otherwise deemed to be amended as of July 1, 2004 as if such conforming changes had been made as of July 1, 2004. In all other respects, the provisions of the Plan are hereby ratified and remain in full force and effect.

Executed and adopted by The PNC Financial Services Group, Inc. by its duly authorized delegate this 30th day of June, 2004.
