WesBanco, Inc. ('WesBanco') (Nasdaq: WSBC) and Western Ohio Financial Corporation ('Western Ohio') (Nasdaq: WOFC) jointly announced today that they have executed a definitive Agreement and Plan of Merger. Paul M. Limbert, President &CEO, representing WesBanco, and John W. Raisbeck, President &CEO, representing Western Ohio, made the joint announcement.

At December 31, 2003, Western Ohio had consolidated assets of $399.5 million, deposits of $248.7 million, loans of $334.5 million and shareholders' equity of $44.4 million. Western Ohio's principal subsidiary is Cornerstone Bank. At December 31, 2003, WesBanco had consolidated assets of $3.4 billion, deposits of $2.5 billion, loans of $1.9 billion and shareholders'equity of $318 million. WesBanco's principal subsidiary is WesBanco Bank, Inc.

Under the terms of the Agreement and Plan of Merger, WesBanco will exchange a combination of its common stock and cash for Western Ohio common stock. Western Ohio shareholders will be able to elect a fixed exchange ratio of 1.18 shares of WesBanco common stock or $35.00 in cash. The election is subject to certain limitations including that 55% of Western Ohio's outstanding shares be exchanged for WesBanco common stock. Common stock received by Western Ohio shareholders is anticipated to qualify as a tax-free exchange.

Based upon a per share value of $35.00, the transaction, approved by the directors of both companies, is valued at $65.2 million. The price represents a Price/Book Value of 140.5%, a Price/Trailing 12 Months Earnings multiple of 24.6 times and a Core Deposit Premium of 10.6%. The acquisition, which will be accounted for as a purchase transaction, is subject to the approvals of the appropriate banking regulatory authorities and the shareholders of Western Ohio. It is expected that the transaction will be completed in the fourth quarter. WesBanco expects the purchase to be neutral to 2004 earnings, excluding acquisition-related charges, and is anticipated to add over 1% to earnings per share in 2005.

Investment advisors involved in the transaction were Keefe, Bruyette & Woods, Inc., representing WesBanco, and Friedman, Billings, Ramsey &Co., Inc. representing Western Ohio.

When the transaction is consummated, the combination of the two banking companies will create a financial services company with approximately $3.9 billion in total assets and with 80 branch banking locations in three states. From east to west, the transaction will expand WesBanco's franchise along the Interstate 70 corridor from Washington, Pennsylvania to Dayton, Ohio. Cornerstone's seven banking offices located in Clark, Greene and Montgomery Counties will combine with WesBanco's 19 Ohio offices and add nearly 50% to its deposit franchise in the state.

'We are looking forward to having Western Ohio's customers, employees and communities join WesBanco. We believe that the combination of WesBanco's products and services with Western Ohio's customer base will create powerful synergies,'said Paul M. Limbert, WesBanco President &CEO. 'Continuity in service and leadership are areas of particular interest and retaining key employees and ties to the communities served by Western Ohio are extremely important in our ability to effect a smooth transition for Western Ohio,'he continued.

'Central to WesBanco's acquisition strategy is pursuing quality banks in our own markets and expanding into new markets that can provide long-term growth potential,'said Mr. Limbert. 'This transaction presents us with an opportunity to expand our Ohio market presence. The Dayton-Springfield market is a natural extension in our growth westward in Ohio,'Mr. Limbert said.

'We believe that our affiliation with WesBanco will benefit our shareholders, customers and employees,'said John W. Raisbeck, President & CEO, Western Ohio Financial Corporation. 'In our markets, supporting our local communities and providing local decision-making will continue to differentiate us from many of our major competitors. WesBanco shares our vision for the future,'he continued.

'This marks the culmination of a process begun several months ago when our financial advisor contacted potential acquirors about the possibility of acquiring Western Ohio,'Mr. Raisbeck continued. 'After reviewing bids received and following consultation with its financial, legal and accounting advisors, the Board of Western Ohio determined that the WesBanco offer was preferable for Western Ohio's shareholders, customers, and employees.'

Mr. Raisbeck added that WesBanco's extensive experience in trusts and investments, commercial lending and technologically advanced banking systems were important factors in determining the merger potential of the combined organization. 'Western Ohio operates in very attractive market areas and has a very strong management team and capable staff. We have been undergoing a transition from a traditional thrift to a community bank in recent years. As part of WesBanco, with its more significant resources, we can now compete for larger commercial transactions and offer trust and wealth management services. We look forward to providing our customers all of the products that are offered by our major competitors while we maintain our community bank orientation. By aligning ourselves with WesBanco, we become a formidable competitor in the Dayton-Springfield market,'Mr. Raisbeck said.

As a result of the merger, it is anticipated that WesBanco will retain an Advisory Board in the Springfield market and add one individual to its banking subsidiary board from the Board of Western Ohio.
