Goerke (412) 762-4550 firstname.lastname@example.org INVESTORS: William H. Callihan (412) 762-8257 email@example.com THE PNC FINANCIAL SERVICES GROUP, INC. AND UNITED NATIONAL BANCORP ANNOUNCE ELECTION DEADLINE FOR PENDING MERGER PITTSBURGH, PA, and BRIDGEWATER, NJ, November 20, 2003 - In connection with the previously announced pending merger between The PNC Financial Services Group, Inc. (NYSE: PNC) and United National Bancorp (NASDAQ: UNBJ), the election deadline for United National shareholders who wish to make an election to receive the merger consideration in cash or shares of PNC common stock, subject to proration, will expire at 5:00 P.M., Eastern Time, on Monday, December 1, 2003. To make a valid election, shareholders must deliver to Computershare Trust Company of New York, the Exchange Agent for the merger, properly completed Forms of Election, together with their stock certificates or properly completed notices of guaranteed delivery, by the election deadline. United National shareholders who do not properly deliver such documentation to the Exchange Agent (at the address specified in the Form of Election) by the election deadline will be unable to choose whether they will receive cash or PNC common stock as merger consideration. Although such non-electing shareholders will be entitled to receive approximately equivalent value per share to the amount paid to electing shareholders, the form of consideration may be paid all in cash, all in PNC common stock, or part in cash and part in PNC common stock. The precise composition of the consideration paid to non-electing shareholders will depend on the remaining pool of cash and PNC common stock available after honoring the cash and stock elections properly made by the other shareholders. The final election results regarding the merger consideration will be announced as soon as possible after the election deadline. United National shareholders may obtain additional copies of the Form of Election by contacting Computershare Trust Company of New York at 1-800-245-7630. After the election deadline, but before the closing of the merger, United National shareholders who have made elections will be unable to revoke or change their elections, sell their shares of United National common stock, or have access to their United National common stock certificates. PNC and United National are working to complete the merger promptly, and expect it to occur in January 2004, subject to customary closing conditions, including regulatory approvals and the approval of shareholders of United National.
