To: Shareholders of FNH Corporation as of May 16, 2001.

Dear Shareholder:

        On May 29, 2001, we sent you notice (the “Original Notice”) of the Annual Meeting of Shareholders of FNH Corporation (“FNH”) to be held on Friday, June 29, 2001. The Original Notice contained a proxy solicitation statement including, among other things, a description of certain proposed transactions between FNH and Promistar Financial Corporation (“Promistar”).

        On June 14, 2001, Promistar announced that it had signed a definitive agreement in which Promistar will merge into FNB Corporation (“FNB”). A copy of the press release is attached.

        Under the terms of the FNH/Promistar agreement, if consummated, Promistar will, subject to adjustment, exchange 15 shares of its common stock for each share of FNH common stock. Under the terms of the Promistar/FNB agreement, if consummated, FNB will, subject to adjustment, exchange 0.926 shares of its common stock for each share of Promistar common stock. As a result, if both transactions are consummated without adjustment of the exchange ratios, each FNH shareholder will receive 13.89 shares of FNB common stock for each share of FNH common stock they hold. FNB common stock is traded on Nasdaq and closed at $25.70 per share on June 18, 2001. At that price, each share of FNH common stock will receive FNB common stock worth approximately $356.97 if both mergers are consummated.

        This news requires us to supplement the proxy solicitation materials enclosed with the Original Notice. For this reason, FNH has decided to postpone the Annual Meeting of Shareholdersuntil such time as we are able to provide you with additional information concerning the proposed Promistar/FNB transaction.

        After we, along with Promistar and FNB, have gathered all the necessary information, we will send you a notice stating the date and place for the rescheduled Annual Meeting and including the supplemental proxy materials. You should read the supplemented proxy materials before making any voting or investment decisions.

        If you have any questions regarding the foregoing, please do not hesitate to contact James Lauffer of FNH at 724-864-7776 or Richard Rose of Buchanan Ingersoll Professional Corporation, counsel to FNH, at 412-562-8425.

Very truly yours,

F.N.B. CORPORATION & PROMISTAR FINANCIAL ANNOUNCE MERGER

NAPLES, FL., and JOHNSTOWN, PA., June 14 - F.N.B. Corporation (Nasdaq: FBAN) and Promistar Financial Corporation (Nasdaq: PRFC) today announced the signing of a definitive agreement in which Promistar will merge into F.N.B. This transaction is expected to be accretive to F.N.B.’s earnings by more than 4% in 2002 and 5% in 2003.

Under the terms of the definitive agreement, F.N.B. will exchange 0.926 shares of its common stock for each share of Promistar common stock. Based on F.N.B.’s June 13 closing price of $26.74 per share, the transaction is valued at approximately $427 million.

Due diligence on the transaction has been completed by both parties and completion of the transaction is subject to the normal regulatory approvals as well as the approval of F.N.B. and Promistar shareholders. The transaction is scheduled for completion in the first quarter of 2002 and is expected to be accounted for as a pooling of interests.

Management expects the combined company to achieve synergies of 18% of Promistar’s non-interest expenses in 2002. On a fully phased-in basis, these synergies are projected to increase to approximately 25%.

The combined company expects to incur one-time, merger-related charges of approximately $41 million, on a pre-tax basis, during 2002 related to staff retention and severance, systems integration, professional fees, investment portfolio restructuring, fixed asset disposals, and other miscellaneous items.

The combined company, headquartered in Naples, Florida, will have more than $6.5 billion in assets, $5.2 billion in deposits and 168 banking offices located in southwest Florida, western Pennsylvania and northeastern Ohio. F.N.B. is the largest independent bank holding company headquartered in Florida. As a result of this merger, F.N.B. will become the eighth largest bank

holding company, based on total deposits, operating in the state of Pennsylvania and the 65^th largest bank holding company in the United States.

“This is a unique opportunity to merge with an organization that shares a similar culture and heritage,”said Gary L. Tice, President and Chief Executive Officer of F.N.B. Corporation. “Promistar is a strong and successful community banking organization that we’ve long admired. The combination of F.N.B. and Promistar will create a franchise that we believe will be the premier financial institution serving western Pennsylvania.”

Promistar Bank currently operates 72 branches and will add another 10 locations upon the completion of its previously announced merger with First National Bank of Herminie in Herminie, Pennsylvania. F.N.B. currently operates 43 branches in western Pennsylvania. Once the merger is completed, all Promistar offices will operate under the First National Bank of Pennsylvania name. At least eight branch offices are expected to be consolidated.

“We are excited about the opportunity to team up with F.N.B.”said John H. Anderson, Chairman and Chief Executive Officer of Promistar Financial Corporation. “Both our employees and customers will be well served by F.N.B.’s long-standing practice of operating with local decision-makers, local employees and local Boards of Directors.”

“This affiliation nearly triples the number of First National Bank offices and adds approximately 1.4 million households to the bank’s market area,”said Steve Gurgovits, President and Chief Executive Officer of First National Bank of Pennsylvania. “We are pleased to be able to offer many new financial services such as life insurance, property and casualty insurance, title insurance and home mortgage lending. These services will be offered under our traditional community banking style that we call Personal Banking.”

Steven C. Ackmann, who currently serves as President and Chief Operating Officer of Promistar, will join First National Bank of Pennsylvania as Senior Executive Vice President and Chief Operating Officer. “I look forward to working with F.N.B. as we combine these two fine community banking organizations into what we believe will become the bank of choice for the citizens of western Pennsylvania,”he said.

F.N.B. Corporation is a diversified financial services company with more than $4.1 billion in total assets. The company currently owns and operates traditional community banks, insurance agencies, a consumer finance company and First National Trust Company with offices located in Florida, Pennsylvania, Ohio and Tennessee. The company has increased cash dividends for 29 consecutive years and has been recognized as a Dividend Achiever by Mergent FIS, formerly known as Moody’s Investors Service.
