Bruce  Knox,   Neil  S.   Strawser  and  Donald  P.  Wood   (collectively,   the
"Shareholders")  entered into a Voting Agreement (each a "Voting Agreement" and,

into the Merger Agreement discussed in Item 4 and in consideration  thereof. 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  information  set  forth  in  Item 4 of  this  Schedule  13D is  hereby
incorporated by reference.

Item 4. Purpose of Transaction.

     (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.

     WesBanco  entered into the Voting  Agreements in connection with the Merger
Agreement. Pursuant to the Voting Agreements, each of the Shareholders agreed to
vote, and has granted to WesBanco an irrevocable  proxy and power of attorney to
vote, his Shares owned as of July 19, 2007 or acquired thereafter:  (i) in favor
of  adoption  and  approval  of  the  Merger   Agreement  and  the  transactions
contemplated thereby, including the Merger; (ii) against any action or agreement
that would result in a breach of any covenant,  representation  or warranty,  or
any other  obligation  or  agreement  of the  Company  contained  in the  Merger
Agreement or of the Shareholder contained in the Voting Agreement, or that would
preclude  fulfillment of a condition under the Merger Agreement to the Company's
and  WesBanco's  respective  obligations  to  consummate  the Merger;  and (iii)
against any  Acquisition  Proposal,  or any  agreement  or  transaction  that is
intended,  or could reasonably be expected,  to impede,  interfere with,  delay,
postpone,  discourage or adversely  affect the consummation of the Merger or any
of the transactions contemplated by the Merger Agreement.

     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.  In
addition,  R. E. Coffman,  Jr., D. Bruce Knox,  David G. Ratz,  Scott J. Hinsch,
Jr.,  and  Miles  R.  Armentrout,   have  entered  into  employment  agreements,
conditioned  on  consummation  of  the  Merger,  with  WesBanco's   wholly-owned
subsidiary, WesBanco Bank, Inc.

     (e) Other than as a result of the Merger  described in Item 4(a) above, not
applicable.

     (f) Not applicable.

     (g) At the effective time of the Merger,  the articles of  incorporation of
WesBanco,  as in effect  immediately  prior to the effective time,  shall be the
articles  of  incorporation  of  the  surviving  corporation  until  amended  in
accordance with applicable law. The bylaws of WesBanco, as in effect immediately
prior to the effective time, shall be the bylaws of the surviving corporation.

     (h) - (i) If the Merger is  consummated  as  planned,  the  Shares  will be
deregistered  under  the  Securities  Exchange  Act of  1934,  as  amended  (the
"Exchange Act"), and delisted from the NASDAQ Global Select Market.

     (j) Other  than as  described  above,  WesBanco  currently  has no plans or
proposals  which relate to or would result in any of the matters listed in Items
4(a)-(j) of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

     (a) - (b) Prior to July 19, 2007, WesBanco was not the beneficial owner (as
defined in Rule 13d-3  promulgated  under the Exchange Act) of any Shares.  Upon
execution of the Voting Agreements, WesBanco may be deemed to have acquired sole

Shareholders.  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. Kidd, D. Bruce Knox,
Neil S.  Strawser  and  Donald  P.  Wood  for a total of  5,400,602  outstanding
Shares).

     (c) The  information  set forth in Item 4 above is  incorporated  herein by
reference.
