The Shareholders are comprised of certain directors and a director emeritus of the Company and their affiliates. WesBanco has not paid additional consideration to the Shareholders or the Company in connection with the execution and delivery of the Voting Agreements.

(a) - (b) On July 19, 2007, the Company, Oak Hill Banks, WesBanco and WesBanco Bank, Inc. entered into an Agreement and Plan of Merger (the "Merger Agreement"). Subject to the terms and conditions of the Merger Agreement, the Company will be merged with and into WesBanco, with WesBanco being the surviving corporation (the "Merger"). As a result of the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger shall be converted into either: (i) $38.00 in cash; (ii) 1.256 shares of WesBanco common stock; or (iii) a combination of cash and WesBanco common stock. The obligations of the parties to the Merger Agreement to effect the Merger are subject to certain conditions, including the approval of the Merger by each of the Company's and WesBanco's shareholders, and the receipt of applicable federal and state bank regulatory approvals.

CUSIP No. 671337103 13D Page 4 of 6 Pages The term "Acquisition Proposal" is defined under the Merger Agreement as any inquiry, offer or proposal (other than an inquiry, offer or proposal from WesBanco), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction. For purposes of the Merger Agreement, the term "Acquisition Transaction" is defined as (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving Company or any of the Company's subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, any assets of Company or any of the Company's subsidiaries representing, in the aggregate, twenty percent (20%) or more of the assets of Company and the Company's subsidiaries on a consolidated basis; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing twenty percent (20%) or more of the votes attached to the outstanding securities of Company or any of the Company's subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning twenty percent (20%) or more of any class of equity securities of Company or any of the Company's subsidiaries; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing. The Voting Agreements also provide that, except under certain limited circumstances, each Shareholder will not sell, assign, transfer or otherwise dispose of or encumber any of such Shareholder's Shares owned as of July 19, 2007 or acquired thereafter. The Voting Agreements will terminate upon the earlier of the effective time of the Merger or the termination of the Merger Agreement in accordance with its terms. The purpose of the transactions contemplated by the Voting Agreements is to support the consummation of the transactions contemplated under the Merger Agreement. (c) Not applicable. (d) Upon the consummation of the Merger, the directors of WesBanco immediately prior to the effective time of the Merger will be the directors of WesBanco, the surviving corporation in the Merger, until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of WesBanco. In addition, under the terms of the Merger Agreement WesBanco will appoint each of the Shareholders except for Evan E. Davis to WesBanco's board of directors at its first meeting after the effective time of the Merger. Upon consummation of the Merger, the officers of WesBanco immediately prior to the effective time of the Merger will be the officers of WesBanco, the surviving corporation in the Merger, each to hold office in accordance with the articles of incorporation and bylaws of WesBanco.

Based on representations made by the Shareholders in the Voting Agreements, the Shareholders subject to the Voting Agreements beneficially own 1,172,047 Shares, constituting approximately 21.7% of the total issued and outstanding Shares (based on 5,345,554 Shares, the number of Shares outstanding as of July 19, 2007 as represented by the Company in the Merger Agreement and the 55,048 vested options held, in aggregate, by John D.
