         Re:  Proposed Acquisition of Western Ohio Financial Corporation

Gentlemen:

     In connection with the registration of the Common Stock of WesBanco, Inc.
("WesBanco") under the provisions of the Securities Act of 1933, you have
requested our opinion regarding the legality of the securities of WesBanco to be
issued as a result of the Agreement and Plan of Merger dated as of April 1,
2004, by and between WesBanco, Western Ohio Financial Corporation, and WOFC,
Inc. ("Merger Agreement").

     In conjunction with this opinion, we have examined such corporate records
of WesBanco, the Merger Agreement, and such other agreements and instruments,
certificates of public officials, certificates of officers and representatives
of WesBanco, and other documents, as we have deemed necessary for purposes of
issuing the opinion hereinafter expressed. All legal proceedings taken thus far
in connection with this issuance of these shares have been in form and substance
satisfactory to us.

     It is our opinion that WesBanco is duly organized and validly existing
under the laws of the State of West Virginia as a bank holding company and that,
when the exchange of stock is completed as contemplated in the foregoing Merger
Agreement, and the effectiveness of the Registration Statement on Form S-4 to be
filed with regard thereto is confirmed by the Securities and Exchange
Commission, the securities being registered will be legally issued, fully paid
and nonassessable under the laws of the State of West Virginia and of the United
States.

     We hereby consent to the inclusion of this opinion as an exhibit to the
above-mentioned Registration Statement on Form S-4 and to the reference to this
firm and its opinions included in the Registration Statement.

                                  Yours truly,

                                  /s/ PHILLIPS, GARDILL, KAISER & ALTMEYER, PLLC
