FOR IMMEDIATE RELEASE

Election Deadline for Sterling Financial Corporation Shareholders
Is March 25, 2008

LANCASTER, PA. (March 13, 2008) – Sterling Financial Corporation of Lancaster, Pa (NASDAQ: SLFI) today reiterated that the election deadline for Sterling shareholders to make merger consideration elections in connection with the proposed merger with The PNC Financial Services Group, Inc. (NYSE: PNC) is 5:00 p.m., New York City time, on March 25, 2008. Sterling shareholders of record wishing to make an election regarding the form of consideration they would prefer to receive must deliver to Computershare, Inc., the Exchange Agent in the merger, the following: properly completed election forms, together with stock certificates, if any, or a properly completed notice of guaranteed delivery. These must be received by Computershare by the election deadline of 5:00 p.m., New York City time, on March 25, 2008.

Sterling shareholders who hold their shares in “street name” may have an election deadline earlier than March 25, 2008. They should carefully review any materials they received from their broker to determine the election deadline applicable to them.

Sterling shareholders are entitled to make an election about the type of merger consideration (cash or shares of PNC common stock) they prefer to receive for each share of Sterling common stock exchanged in the merger. In each case, such consideration will have a value approximately equal to the sum of (a) 0.1543 multiplied by the average of the closing prices on the New York Stock Exchange for PNC common stock during the five trading days ending the day before the completion of the merger and (b) $7.60. All elections are subject to the proration procedures provided in the merger agreement. As a result, shareholders who elect to receive entirely cash or entirely PNC common stock may receive a combination of cash and common stock, and shareholders who elect to receive a combination of cash and PNC common stock may receive cash and common stock in a different proportion from what they elected.

Shareholders who do not submit a properly completed election form to Computershare by the election deadline will be deemed to have no preference as to the form of consideration they will receive and will receive cash, PNC shares of common stock or a combination of both, depending on the elections of other Sterling shareholders. After Sterling shareholders have made their elections and tendered their Sterling shares of common stock to Computershare, they will be unable to sell or transfer their shares of Sterling common stock unless they validly revoke their election prior to the election deadline.

All of the documents necessary to make an election were previously mailed to Sterling shareholders of record on or about February 15, 2008. Sterling shareholders of record may obtain additional copies of the election documents by contacting the Information Agent, Georgeson Inc., at (800) 319-6872. Sterling shareholders who hold their shares in “street name” may obtain additional copies of the election documents by contacting their broker.

A more complete description of the merger consideration and the proration procedures applicable to elections is contained in the proxy statement/prospectus dated February 11, 2008, mailed to Sterling shareholders of record on or about February 13, 2008. Sterling shareholders are urged to read the proxy statement/prospectus carefully and in its entirety. Copies of the proxy statement/prospectus may be obtained for free by following the instructions below under “Additional Information About the PNC/Sterling Financial Corporation Transaction.”

The proposed merger remains subject to the expiration of all regulatory waiting periods and the satisfaction of the other conditions contained in the merger agreement.
