stock at this time. Following approval and consummation of the transaction,

stock certificates and receiving certificates for the shares of Wesbanco common
stock to be issued in the merger.



                                          Sincerely,

or by proxy at the Special Meeting must vote in favor of the merger in order to
approve the merger. As of January 10, 2002, there were 3,129,674 shares of
American common stock outstanding, held by approximately 1,732 holders of
record.


     You can vote your shares by attending the Special Meeting and voting in
person, or by marking the enclosed Proxy Card with your vote, signing it and
mailing it in the enclosed return envelope. You can change your vote as late as
the date of the Special Meeting either by sending in a new Proxy received prior
to the Special Meeting or by attending the Special Meeting and voting in person.


RIGHT TO DISSENT FROM THE MERGER



     You have the right to dissent from the merger. This means that if you do
not vote in favor of the merger, you may make a written demand to American for
payment in cash of the fair value of your shares. See "The Merger -- Rights of
Dissenting Shareholders" beginning on page 24.


CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     We intend the merger to be a tax free reorganization for federal income tax
purposes. If we obtain this treatment, you will not recognize any gain or loss
for federal income tax purposes upon receipt of shares of Wesbanco common stock
in exchange for your shares of American common stock. However, any cash you
receive in lieu of fractional shares will constitute taxable income.

     Because of the complexity of the tax laws and the individual nature of the
tax consequences of the merger, you should consult your own tax advisor
concerning all federal, state, local and foreign tax consequences of the merger
that may apply to you.

the Wesbanco Board of Directors upon Jeremy McCamic's resignation. Wesbanco has
agreed to nominate Abigail M. Feinknopf and Jay T. McCamic as directors until
each has served at least a full 3 year term. Abigail M. Feinknopf and Jay T.
McCamic are the children of Jeremy C. McCamic.



     Certain officers of American will also enter into employment agreements,

DESCRIPTION OF THE MERGER AGREEMENT


     American will be merged with and into AB Corporation, with AB Corporation,
a wholly owned subsidiary of Wesbanco formed solely for the purpose of effecting
the merger, continuing as the surviving corporation. For each share of American
common stock you own, you will receive 1.1 shares of Wesbanco common stock.
Completion of the merger is subject to the satisfaction or waiver of the
conditions specified in the Merger Agreement, including, among others, those
listed below:



     - the approval of the Merger Agreement by the shareholders of American;


     - the exercise of dissenters' rights in accordance with the Ohio Revised
       Code by not more than 10% of the holders of American common stock; and


     - on or before the date the merger closes, the receipt of an opinion from
       tax counsel for Wesbanco to the effect that for federal income tax
       purposes the merger will be treated as a tax free reorganization within
       the meaning of Section 368(a) of the Internal Revenue Code, and regarding
       certain other tax matters.



     Termination of the Merger Agreement.  The parties may mutually agree to
terminate the Merger Agreement at any time before the merger is completed.
American may also terminate the Merger Agreement if the average bid price for
Wesbanco common stock for the 30 calendar days preceding the fifth business day
before closing of the merger falls below $16.00 per share.



     Either Wesbanco or American may also terminate the Merger Agreement under
other circumstances described in detail in this Proxy Statement, including,
without limitation, the failure of the merger to close by March 31, 2002.



     Effective Date of the Merger.  We expect the merger to be completed as soon
as practicable after shareholder approval has been received. We expect this to
occur on or about March 1, 2002.

Reserve approved the merger on January 7, 2002.


STOCK OPTION AGREEMENT


     American and Wesbanco entered into a Stock Option Agreement dated February
22, 2001, pursuant to which American granted Wesbanco the option to purchase up
to 622,805 shares of American common stock at a price of $18.00 per share upon
the occurrence of certain events. American granted Wesbanco this option to
induce Wesbanco to enter into the Merger Agreement and to increase the
likelihood that the corporations would complete the merger.


                                        2


     The Stock Option Agreement could discourage other companies from trying or
proposing to combine with American before the completion of the merger. The
Stock Option Agreement is attached as Annex C to this document.


     Wesbanco cannot exercise this option unless certain events occur. These
events include business combinations or acquisition transactions relating to
American and American's failure to satisfy certain provisions in the Merger
Agreement. Neither American nor Wesbanco is aware of any event, as of the date
of this document, that would permit Wesbanco to exercise this option. See "Stock
Option Agreement" beginning on page 35 for more information about the Stock
Option Agreement.

     You are urged to obtain current market quotations for Wesbanco and American
common stock. Prices at which Wesbanco and American common stock may trade prior
to the merger may not be indicative of prices at which Wesbanco common stock may
trade following the merger.

WESBANCO COMMON STOCK DIVIDEND POLICY

     Wesbanco has historically declared and paid cash dividends on a quarterly
basis. Wesbanco anticipates that, after the merger, it will initially declare
quarterly dividends on shares of Wesbanco common stock of $0.23 per share. You
are cautioned, however, that the Wesbanco Board of Directors may, at any time
and without notice, stop declaring dividends or reduce the amount of the
dividend.

     Whether Wesbanco pays a dividend, and the amount of any dividend, will
depend upon Wesbanco's results of operations, financial condition, cash
requirements, future prospects, limitations imposed by credit agreements or
senior securities and other factors deemed relevant by the Wesbanco Board of
Directors. Because Wesbanco's principal source of income is dividends from its
subsidiaries, its ability to pay future dividends will depend upon the financial
condition and earnings of its subsidiaries.

     Wesbanco may pay dividends at the discretion of its Board of Directors out
of any funds legally available for the payment of dividends under West Virginia
law. Under the West Virginia Corporation Act, dividends may be paid out of
unreserved and unrestricted earned surplus, and, additionally, in certain
circumstances and with the affirmative vote of holders of a majority of
Wesbanco's outstanding shares, out of capital surplus. Wesbanco may never pay a
dividend, however, if, at the time of or after payment of the dividend, it is or
would be insolvent.

     Under applicable federal regulations, appropriate bank regulatory agency
approval is required if the total of all dividends declared by a bank in any
calendar year exceeds the available retained earnings and exceeds the aggregate
of the bank's net profits (as defined by regulatory agencies) for that year and
its retained net profits for the preceding two years, less any required
transfers to surplus or a fund for the retirement of any preferred stock. As of
September 30, 2001, Wesbanco's banking subsidiary could not have declared any
dividends to be paid to Wesbanco without prior approval from regulatory
agencies.

AMERICAN COMMON STOCK DIVIDEND POLICY


     American has recently declared and paid dividends of $0.15 on a quarterly
basis on American common stock. American may pay dividends at the discretion of
its Board of Directors out of any funds legally available for the payment of
dividends under Ohio law. Notwithstanding the foregoing, American has agreed not
to declare any dividends in 2002 other than its normal quarterly dividend of
$0.15 per share in respect of the fourth quarter of 2001. The Ohio general
corporation law generally provides that American may declare and pay dividends
to its shareholders, provided that the dividend does not exceed the combination
of the income and surplus of American and is not in violation of the rights of
the holders of shares of any other class. Surplus is defined generally as the
excess of American's assets plus stated capital over its liabilities. American
may never pay a dividend, however, if at the time of or after payment of the
dividend, it is or would be insolvent.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION



     The following Unaudited Pro Forma Condensed Financial Information is based
on the historical financial statements of Wesbanco and American and has been
prepared to illustrate the financial effect of the merger described below. The
pro forma financial information should be read in conjunction with Wesbanco's
and American's unaudited consolidated financial statements for the nine months
ended September 30, 2001 and audited consolidated financial statements for the
year ended December 31, 2000.



     The Unaudited Pro Forma Condensed Combined Balance Sheet as of September
30, 2001 assumes the merger was accounted for as a purchase and consummated on
September 30, 2001. The Unaudited Condensed Combined Statements of Income for
the nine months ended September 30, 2001 and for the year ended December 31,
2000, give effect to the merger of American as if such transaction had been
effective during the entire period shown. These pro forma financial statements
reflect the merger based upon preliminary purchase accounting adjustments.
Actual adjustments will be made on the basis of evaluations as of the effective
date of the merger and, therefore, may differ from those reflected in the
Unaudited Pro Forma Condensed Financial Information.



     Estimates of non-recurring merger expenses and cost savings expected to
occur after the date of consummation have not been included in the pro forma
financial information. Non-recurring expenses are projected to range in total
from $3.5 million to $4 million. Wesbanco projects cost savings associated with
the merger to approximate 25% to 30% of American's estimated annualized pre-tax
operating expenses of $13.5 million for 2001. These estimates may differ from
the actual costs incurred and cost savings achieved in the merger.



     In conjunction with the merger, Wesbanco will be required to divest the
deposits of one office of American to address a possible anti-trust issue. This
office of American, with total deposits as of September 30, 2001 of $16.5
million, or 0.7% of pro forma combined deposits, is considered immaterial to the
transaction and, therefore, has not been adjusted for in the pro forma financial
information.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED FINANCIAL INFORMATION



NOTE A



     The pro forma adjustments represent the purchase accounting entries to
record the merger of American. The excess of the purchase price over the fair
value of the net assets acquired is allocated to goodwill. Estimated fair value
adjustments included in the Unaudited Pro Forma Condensed Balance Sheet have
been determined based on information available as of September 30, 2001. Because
the final determination of fair values of asset and liabilities will be made
based on the fair values as of the effective date of the merger, the final
amounts may differ from the estimates provided herein. Fair value adjustments
are amortized on a straight-line basis over their estimated remaining lives. Tax
expense related to net fair value adjustments is calculated at a 40% tax rate.



     Included in the pro forma adjustments is an allocation of the purchase
price to core deposit intangibles. Under the new accounting standards, SFAS No.
141 and No. 142, a core deposit intangible is separated from goodwill and
amortized over its remaining useful life. Amortization of core deposit
intangible is a non-deductible expense for tax purposes. The remaining goodwill
intangible is not subject to amortization under the new standards. The remaining
goodwill intangible will be periodically evaluated for possible impairment.



NOTE B



     The pro forma adjustment represents estimated direct acquisition costs of
approximately $3 million. These costs, which are accrued as liabilities, include
certain severance payments, legal fees and accounting and advisory fees.


                                        11



                                  RISK FACTOR


 WESBANCO'S RESULTS OF OPERATIONS ARE SIGNIFICANTLY AFFECTED BY THE ABILITY OF
 ITS BORROWERS TO REPAY THEIR LOANS.

     Lending money is an essential part of the banking business, but borrowers
do not always repay their loans. The risk of non-payment is affected by, among
other things, credit risks of a particular borrower, changes in economic and
industry conditions, the duration of the loan and, in the case of a
collateralized loan, uncertainties as to the future value of the collateral.
With respect to Wesbanco, a large portion of its loans have been made to
borrowers that are, directly or indirectly, financially dependent on the
continued viability of certain employers, including those in the steel industry,
that have a significant presence in Wesbanco's principal markets. Some of these
employers are in dire financial straits and may reduce the size of their work
forces or discontinue some or all of their operations. The loans that Wesbanco
has made to borrowers that are financially dependent upon these employers may be
adversely affected by continued financial troubles of such employers.

                              THE SPECIAL MEETING

Arrangements will also be made with custodians, nominees and fiduciaries for the
forwarding of solicitation materials to the beneficial owners of American common
stock held of record by such persons. American may reimburse these custodians,
nominees and fiduciaries for reasonable out-of-pocket expenses they incur in
connection therewith. DO NOT SEND YOUR STOCK CERTIFICATES WITH YOUR PROXY CARD.


                                   THE MERGER


     The following description of the terms of the merger is qualified in its
entirety by reference to the provisions of the Merger Agreement and the First
Amendment thereto, which are attached to this Proxy Statement as Annex A and
Annex B, respectively, and are incorporated into this document by reference. You
are strongly encouraged to read the Merger Agreement and the First Amendment for
a more complete description of the terms of the merger.


BACKGROUND OF THE MERGER

     American and Wesbanco had informal discussions concerning a possible
combination of the two banks as far back as 1982. For the most part, these
discussions were informal, nonspecific, and generally indicated an interest on
the part of both institutions to consider a possible combination at some future
date.

     Specific discussions were undertaken in October of 1999 between Jeremy C.
McCamic, the Chairman and Chief Executive Officer of American, and James C.
Gardill, the Chairman of Wesbanco, with their first meeting occurring on October
8, 1999. These discussions continued through October and November of 1999 with
the discussions expanded to include Brent Richmond, the President of American,
and Edward M. George, the former President and Chief Executive Officer of
Wesbanco. The parties were unable to achieve a

                                        13


satisfactory agreement concerning a possible merger of the two banks and,
accordingly, the discussions were terminated on or about January 14, 2000.

     On August 15, 2000, the Mergers and Acquisitions Committee of American
reviewed strategic alternatives for American. After considerable discussion, the
committee concluded that exploring a possible merger transaction would be
beneficial to American and its shareholders. The full Board of Directors
considered this matter, and after a lengthy discussion approved the engagement
of McDonald Investments Inc. to serve as American's financial advisor in
connection with a possible sale or merger of American. McDonald Investments, in
consultation with American, prepared a Confidential Memorandum containing June
30, 2000 financial information. In October of 2000, McDonald Investments
contacted a number of financial institutions that McDonald or American had
identified as possible acquirors to determine the extent to which, if any, there
was interest in acquiring American.

     On November 16, 2000, representatives of McDonald Investments met with the
Mergers and Acquisition Committee of American and reported that they had
received three preliminary indications of interest in acquiring American.
McDonald Investments prepared an analysis of the three indications of interest
and the institutions expressing such interest. The analysis prepared by McDonald
included an analysis of each institution's profitability, key financial ratios,
future projections and relative market valuations.

     Subsequently, on November 17, 2000, Mr. George sent a letter to Mr. McCamic
expressing renewed interest in reinstating the discussions toward a possible
combination of the two banking corporations. The Wesbanco Planning and
Acquisitions Committee met on December 7, 2000, and addressed parameters of a
proposal. In response to Mr. George's letter, Mr. McCamic, Mr. Richmond, Mr.
George and Mr. Gardill met on December 14, 2000, and initiated discussions
concerning a possible combination of the two organizations. These discussions
continued on December 18th, December 20th, December 22nd, and were briefly
suspended on December 23rd, 2000. Mr. Gardill and Mr. McCamic then met again on
January 8, 2001, and a subsequent meeting was held with Mr. George, Mr. McCamic,
Mr. Gardill and Mr. McCamic's investment advisor, Charles Crowley of McDonald
Investments Inc., on January 11, 2001.

     The Wesbanco Executive Committee met and reviewed the progress of the
negotiations and addressed specific details of a proposal on January 17, 2001.
Additional discussions were held between the parties on January 15th, February
6th, 7th, 12th and February 14th at which latter meeting substantive terms and
conditions of the merger were agreed upon. Final details were worked out at
meetings on February 16th and February 19th with the resulting Agreement and
Plan of Merger executed on February 22, 2001, after consideration and unanimous
approval of the transaction by the Wesbanco Board of Directors on that date.

     Subsequently, in early June 2001, Wesbanco was notified by the Federal
Reserve of a preliminary determination by the Federal Reserve of a downgrading
of the Community Reinvestment Act rating for Wesbanco Bank to "Needs
Improvement," which had the effect of precluding Wesbanco from obtaining the
Federal Reserve's approval of the acquisition of American. The Federal Reserve
issued its final ruling on July 31, 2001 sustaining the downgrade. Wesbanco
successfully appealed this ruling and on October 22, 2001, its rating was
upgraded to "Satisfactory," thereby permitting Wesbanco to proceed with the
application for approval of the American acquisition. Wesbanco and American
entered into the First Amendment to the Merger Agreement to extend from December
31, 2001 to March 31, 2002 the date by which American's acquisition by Wesbanco
must be completed.

     As a result of the regulatory matters described in the preceding paragraph,
Wesbanco lost its opportunity to acquire Freedom Bancshares, a small transaction
that had been announced and for which regulatory approval had been received.
Prior to the scheduled closing, Wesbanco was notified that the Community
Reinvestment Act downgrade would preclude it from closing that transaction.
After Freedom notified Wesbanco that it did not wish to extend the date by which
its acquisition must close, Freedom and Wesbanco negotiated a mutually
satisfactory termination of the transaction.

                                        14


RECOMMENDATION OF THE AMERICAN BOARD

     The Board of Directors of American believes that the merger and the Merger
Agreement are advisable and are fair to and in the best interest of American and
its shareholders. THE BOARD OF DIRECTORS OF AMERICAN UNANIMOUSLY RECOMMENDS THAT
THE AMERICAN SHAREHOLDERS VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT AND THE
MERGER.

OPINION OF AMERICAN'S FINANCIAL ADVISOR

     American retained McDonald Investments Inc. ("McDonald") to act as its
financial advisor in connection with a possible merger and related matters. As
part of its engagement, McDonald agreed, if requested by American, to render an
opinion with respect to the fairness, from a financial point of view, to the
holders of American common stock, of the merger consideration as set forth in
the agreement. McDonald is a nationally recognized specialist for the financial
services industry, in general, and for banks in particular. McDonald is
regularly engaged in evaluations of similar businesses and in advising
institutions with regard to mergers and acquisitions, as well as raising debt
and equity capital for such institutions. American selected McDonald as its
financial advisor based upon McDonald's qualifications, expertise and reputation
in such capacity.


     McDonald delivered a written opinion dated February 22, 2001 that the
exchange ratio was fair to American shareholders, from a financial point of
view, as of the date of such opinion. McDonald updated its February 22, 2001
opinion as of the date of this Proxy Statement. No limitations were imposed by
American on McDonald with respect to the investigations made or the procedures
followed in rendering its opinion.



     THE FULL TEXT OF MCDONALD'S WRITTEN OPINION TO THE AMERICAN BOARD, DATED AS
OF THE DATE OF THIS PROXY STATEMENT, WHICH SETS FORTH THE ASSUMPTIONS MADE,
MATTERS CONSIDERED AND EXTENT OF REVIEW BY MCDONALD, IS ATTACHED AS ANNEX D AND
IS INCORPORATED HEREIN BY REFERENCE. YOU SHOULD READ THE FAIRNESS OPINION
CAREFULLY AND IN ITS ENTIRETY. THE FOLLOWING SUMMARY OF MCDONALD'S OPINION IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE OPINION.
MCDONALD'S OPINION IS ADDRESSED TO THE AMERICAN BOARD AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY SHAREHOLDER OF AMERICAN AS TO HOW SUCH SHAREHOLDER SHOULD
VOTE AT THE AMERICAN SPECIAL MEETING DESCRIBED IN THIS DOCUMENT.


     McDonald, in connection with rendering its original opinion:

     - reviewed American's Annual Reports to Shareholders and Annual Reports on
       Form 10-K for each of the years ended December 31, 2000, December 31,
       1999, and December 31, 1998, including the audited financial statements
       contained therein, and American's Quarterly Reports on Form 10-Q for each
       of the quarters ended September 30, 2001, June 30, 2001, and March 31,
       2001;

     - reviewed Wesbanco's Annual Reports to Shareholders and Annual Reports on
       Form 10-K for each of the years ended December 31, 2000, December 31,
       1999, and December 31, 1998, including the audited financial statements
       contained therein, and Wesbanco's Quarterly Reports on Form 10-Q for each
       of the quarters ended March 31, 2001, June 30, 2001, and March 31, 2001;

     - reviewed certain other public and non-public information, primarily
       financial in nature, relating to the respective businesses, earnings,
       assets and prospects of American and Wesbanco provided to McDonald or
       publicly available;

     - participated in meetings and telephone conferences with members of senior
       management of American and Wesbanco concerning the financial condition,
       business, assets, financial forecasts and prospects of the respective
       companies, as well as other matters McDonald believed relevant to its
       inquiry;

     - reviewed certain stock market information for American common stock and
       Wesbanco common stock, and compared it with similar information for
       certain companies, the securities of which are publicly traded;

     - compared the results of operations and financial condition of American
       and Wesbanco with that of certain companies, which McDonald deemed to be
       relevant for purposes of the opinion;

                                        15


     - reviewed the financial terms, to the extent publicly available, of
       certain acquisition transactions, which McDonald deemed to be relevant
       for purposes of the opinion;

     - reviewed the merger agreement dated February 22, 2001 as amended and its
       schedules and exhibits and certain related documents;

     - reviewed the proxy statement for the merger; and

     - performed such other reviews and analyses as McDonald deemed appropriate.


     The written opinions provided by McDonald to American (as of February 22,
2001 and as of the date of this Proxy Statement) were necessarily based upon
economic, monetary, financial market and other relevant conditions as of the
dates thereof.


     In connection with its review and arriving at its opinion, McDonald relied
upon the accuracy and completeness of the financial information and other
pertinent information provided by American and Wesbanco to McDonald for purposes
of rendering its opinion. McDonald did not assume any obligation to
independently verify any of the provided information as being complete and
accurate in all material respects. With regard to the financial forecasts
established and developed for American and Wesbanco with the input of their
respective managements, as well as projections of cost savings and operating
synergies, McDonald assumed that this information reflects the best available
estimates and judgments of American and Wesbanco as to the future performance of
the separate and combined entities and that the projections provided a
reasonable basis upon which McDonald could formulate its opinion. Neither
American nor Wesbanco publicly discloses such internal management projections of
the type utilized by McDonald in connection with McDonald's role as financial
advisor to American. Therefore, such projections cannot be assumed to have been
prepared with a view towards public disclosure. The projections were based upon
numerous variables and assumptions that are inherently uncertain, including,
among others, factors relative to the general economic and competitive
conditions facing American and Wesbanco. Accordingly, actual results could vary
significantly from those set forth in the respective projections.

     McDonald does not claim to be an expert in the evaluation of loan
portfolios or the allowance for loan losses with respect thereto and therefore
assumes that such allowances for American and Wesbanco are adequate to cover
such losses. In addition, McDonald does not assume responsibility for the review
of individual credit files and did not make an independent evaluation, appraisal
or physical inspection of the assets or individual properties of American or
Wesbanco, nor was McDonald provided with such appraisals. Furthermore, McDonald
assumes that the merger will be consummated in accordance with the terms set
forth in the agreement, without any waiver of any material terms or conditions
by American, and that obtaining the necessary regulatory approvals for the
merger will not have an adverse effect on either separate institution or the
combined entity. In particular, McDonald assumes that the merger will be
recorded as a "purchase" in accordance with generally accepted accounting
principles.

     In connection with rendering its opinion to American's Board, McDonald
performed a variety of financial and comparative analyses, which are briefly
summarized below. Such a summary of analyses does not purport to be a complete
description of the analyses performed by McDonald. Moreover, McDonald believes
that these analyses must be considered as a whole and that selecting portions of
such analyses and the factors considered by it, without considering all such
analyses and factors, could create an incomplete understanding of the scope of
the process underlying the analyses and, more importantly, the opinion derived
from them. The preparation of a financial advisor's opinion is a complex process
involving subjective judgments and is not necessarily susceptible to partial
analyses or a summary description of such analyses. In its full analysis,
McDonald also included assumptions with respect to general economic, financial
market and other financial conditions. Furthermore, McDonald drew from its past
experience in similar transactions, as well as its experience in the valuation
of securities and its general knowledge of the banking industry as a whole. Any
estimates in McDonald's analyses were not necessarily indicative of actual
future results or values, which may significantly diverge more or less favorably
from such estimates. Estimates of company valuations do not purport to be
appraisals nor to necessarily reflect the prices at which companies or their
respective securities

                                        16


actually may be sold. None of the analyses performed by McDonald were assigned a
greater significance by McDonald than any other in deriving its opinion.

     Accretion/Dilution Analysis:  On the basis of financial projections
developed with the assistance of management, and estimates of on-going cost
savings accruing to the pro forma company, as well as estimated one-time costs
related to the transaction, McDonald compared pro forma equivalent earnings,
cash dividends, book value and tangible book value to the stand-alone
projections for American and Wesbanco. No assumptions were made regarding
revenue enhancements following the completion of the transaction.

     The accretion/dilution analysis demonstrated, among other things, the
merger would result in:

     - An estimated twenty-five percent (25%) accretion to diluted earnings per
       share for American shareholders in the first year of combined operations,
       and an estimated twenty-four percent (24%) accretion for each year over
       the period of the analysis;

     - Less than one percent (1%) accretion to earnings for Wesbanco
       shareholders in the first year of combined operations;

     - An estimated sixty-seven percent (67%) accretion in cash dividends in the
       first year for American shareholders, assuming Wesbanco maintained its
       current dividend policy;

     - No change in cash dividends for Wesbanco shareholders;

     - An estimated twelve percent (12%) accretion to book value and less than
       one percent (1%) accretion to tangible book value for American
       shareholders; and

     - An estimated six percent (6%) accretion to book value and less than one
       percent (1%) dilution to tangible book value for Wesbanco shareholders.

     Contribution Analysis:  McDonald compared the contribution of American to
the pro forma company relative to the approximate ownership of the pro forma
company. The analysis indicated that American shareholders would own
approximately 16.1% of the pro forma shares of Wesbanco. American's approximate

     Comparable Transaction Analysis:  McDonald reviewed and compared financial
performance and pricing information for groups of comparable bank merger
transactions announced in the twelve months ended November 30, 2001 that it
deemed pertinent to an analysis of the merger. The pricing ratios for the merger
were compared to the median ratios of (1) price to tangible book value, (2)
price to last twelve months earnings, and (3) tangible book value premium to
core deposits for each of the following comparable transaction groups:

     - all bank acquisitions in the United States ("All U.S. Banks");

     - all Midwest bank acquisitions ("Midwest Banks");

                                        17


     - all bank acquisitions in the United States involving acquired banks with
       assets of $500 million-$1 billion ("Banks -- Assets $500mm-$1b");

     - all bank acquisitions in the United States involving acquired banks with
       returns on average equity of 7%-10% ("Banks -- ROAE 7%-10%");

     McDonald also selected twelve bank acquisitions announced since September
30, 2000 that McDonald believed were the most comparable to American in terms of
asset size, tangible capital and profitability (the "Guideline Transactions");

Note: All ratios reflect median values.

(1) American pricing data based on per share consideration of $21.31.

(2) Last twelve months fully-diluted earnings per share (assuming Treasury
    method of accounting for stock options).

(3) Premium over tangible book value as a percentage of core deposits.

     McDonald determined that the value of the proposed merger fell within the
range of similar transactions represented by the comparable groups based on
multiples of trailing twelve months earnings. The price to tangible book value
and tangible book value premium to core deposits were lower than the comparable
groups, but these ratios were considered to be less meaningful due to
significant fluctuations in book value as a result of gains in the Bank's
securities portfolio.

     Comparable Company Analysis:  McDonald reviewed and compared stock market
data and selected financial information for Wesbanco as of November 30, 2001
with corresponding information for actively-

    levels: Chemical Financial Corp., Corus Bankshares, Inc., First Community
    Bancshares, Inc. (VA), First Financial Bancorp. (OH), First Financial
    Bankshares, Inc. (TX), First Merchants Corp., Frontier Financial Corp.,
    Hancock Holding Co., Omega Financial Corp., Park National Corp., S&T
    Bancorp, Inc., and Texas Regional Bancshares, Inc.

(3) At or for the twelve months ended September 30, 2001, unless otherwise
    noted.

     The analysis revealed that Wesbanco traded at a discount to banks included
in the comparable groups based on price to earnings and price to tangible book
value. Due to its lower stock price, Wesbanco had a higher dividend yield than
the comparable groups.

     Due Diligence Examination of Wesbanco:  McDonald reviewed its on-site due
diligence examination of Wesbanco. McDonald examined Wesbanco's historical
balance sheets and income statements, along with recent operating results and a
variety of financial ratios through September 30, 2001. McDonald discussed
Wesbanco's business strategy, strengths and weaknesses, profitability, growth,
net interest margin, non-interest income, operating expenses, intangible assets,
funding and deposit composition, market share and geographic coverage, capital,
asset quality and reserve coverage, concentrations of credit and loan portfolio
composition, interest-rate risk, foreign investments, mergers and acquisitions,
subsidiary activities, culture, stock pricing, recent bank analysts' reports,
and other issues.

     NO COMPANY USED AS A COMPARISON IN THE ABOVE ANALYSES IS IDENTICAL TO
AMERICAN, WESBANCO OR THE COMBINED ENTITY AND NO OTHER TRANSACTION IS IDENTICAL
TO THE MERGER. ACCORDINGLY, AN ANALYSIS OF THE RESULTS OF THE FOREGOING IS NOT
PURELY MATHEMATICAL; RATHER, SUCH ANALYSES INVOLVE COMPLEX CONSIDERATIONS AND
JUDGMENTS CONCERNING DIFFERENCES IN FINANCIAL MARKET AND OPERATING
CHARACTERISTICS OF THE COMPANIES AND OTHER FACTORS THAT COULD AFFECT THE PUBLIC
TRADING VOLUME OF THE COMPANIES TO WHICH AMERICAN, WESBANCO AND THE COMBINED
ENTITY ARE BEING COMPARED.


     IN CONNECTION WITH THE DELIVERY OF ITS OPINION DATED AS OF THE DATE OF THIS
PROXY STATEMENT, MCDONALD PERFORMED PROCEDURES TO UPDATE, AS NECESSARY, CERTAIN
OF THE ANALYSES DESCRIBED ABOVE AND REVIEWED THE ASSUMPTIONS ON WHICH THE
ANALYSES DESCRIBED ABOVE WERE BASED AND THE FACTORS CONSIDERED IN CONNECTION
THEREWITH. MCDONALD DID NOT PERFORM ANY ANALYSES IN ADDITION TO THOSE DESCRIBED
ABOVE IN UPDATING THE OPINION.


                                        19


     American has agreed to pay McDonald a fee equal to one percent of the
"Transaction Value" for financial advisory services in connection with the
proposed merger. The Transaction Value is equal to the number of shares of
American common stock outstanding on February 22, 2001 (net of treasury shares)
plus the number of shares underlying options to acquire American common stock
outstanding on that date, multiplied by the fair market value of the shares of
Wesbanco common stock to be received in the merger. The fair market value of the
shares of Wesbanco common stock will be the average of the closing prices for
the 10 trading days ending on the date of closing. Based on a value of $21.31
per share, McDonald's total fee would be approximately $665,000. McDonald has
received $100,000 to date. The remainder is payable upon consummation of the
proposed merger. In addition, American has agreed to reimburse McDonald for all
reasonable out-of-pocket expenses, incurred by it on American's behalf, and to
indemnify McDonald against certain liabilities, including any which may arise
under the federal securities laws.

     McDonald is a member of all principal securities exchanges in the United
States and in the conduct of its broker-dealer activities has from time to time
purchased securities from, and sold securities to, American and/or Wesbanco. As
a market maker, McDonald may also have purchased and sold the securities of
American and/or Wesbanco for McDonald's own account and for the accounts of its
customers.

AMERICAN'S REASONS FOR THE MERGER

     American's Board of Directors believes that the merger is in the best
interest of American and its shareholders and has approved the Merger Agreement.
In the course of approving the Merger Agreement and recommending adoption of the
Merger Agreement by the holders of American common stock, the Board of
Directors, without assigning any relative or specific weights, considered a
number of factors, including, without limitation, the following:

     - the value of the Wesbanco common stock to be received by American
       shareholders based on the exchange ratio in relation to the market value,
       book value, earnings per share and dividend rates of American common
       stock;

     - the reputation and business practices of Wesbanco and its management as
       they would affect the employees of American;

     - the impact of the merger on the depositors, customers and communities
       served by American;

     - the opinion of McDonald Investments Inc.;

     - the general structure of the transaction and the compatibility of
       management and business philosophy;

     - the financial results that could be expected in light of the geographic
       location of operations of Wesbanco and American and the compatibility of
       those operations; and

     - industry and economic conditions.

WESBANCO'S REASONS FOR THE MERGER


     The Board of Directors of Wesbanco considered a number of reasons in voting
to approve the proposed merger. First, the merger will provide Wesbanco with the
opportunity to significantly expand its existing franchise to include markets
which it perceives offer significant growth opportunities in Washington,
Pennsylvania, and Columbus, Ohio. Second, the transaction also affords Wesbanco
an opportunity to expand its market reach in the Upper Ohio Valley by adding
offices in new communities, such as Shadyside, Steubenville, Cambridge and St.
Clairsville. Third, the transaction offers significant in-market consolidations
through the consolidation of offices in Wheeling and Weirton which will offer
significant cost saving opportunities in the transaction. Fourth, the
transaction will permit Wesbanco to expand the markets in which it can offer its
broad array of commercial and consumer loan products. Fifth, it will present
Wesbanco with opportunities to market its WesMark Funds in significant growth
markets and give it an opportunity to expand its trust and investment services.
In summary, the Board of Directors of Wesbanco concluded that the in-market
consolidation synergies and cost savings, together with the market expansion
opportunities for products, services and new business, provided a unique balance
of consolidation and growth which would

                                        20


permit Wesbanco to expand its markets while at the same time increasing earnings
through a significant consolidation in a meaningful way.

     The Board also considered the geographic overlay of American's offices and
Wesbanco's offices. American's offices match up well with Wesbanco's offices
north-south along the Ohio River providing offices in communities not presently
served by Wesbanco in several key communities. Additionally, American expands
Wesbanco's already existing distribution network along Interstate 70 by
expanding east-west from Washington, Pennsylvania, to Columbus, Ohio. Finally,
they also add an office in Cambridge, Ohio, which completes a triangular
expansion permitting Wesbanco to provide full coverage north-south along
Interstate 77 from Parkersburg, West Virginia, to Cambridge, Ohio, and east-west
along Interstate 70 from Wheeling, West Virginia, to Cambridge, Ohio. This
expansion would permit Wesbanco to fill in gaps in existing markets and tie
together communities and markets where it already has a significant presence.


INTERESTS OF CERTAIN PERSONS IN THE MERGER



     As of January 10, 2002, directors and officers of American beneficially
owned, in the aggregate, 949,820 shares of American common stock, representing
approximately 30.35% of the outstanding shares of American common stock.


     All of American's directors and officers that own American common stock
will, as a result of the merger, obtain an equity interest in Wesbanco in
exchange for their shares of American common stock. Each of them will receive
the same number of shares of Wesbanco common stock for each share of American
common stock owned by him or her as every other American shareholder. Directors
and officers of American will be treated the same as other American
shareholders, except that they may be subject to certain restrictions on any
resale of Wesbanco common stock received by them pursuant to the merger.


     As of the January 10, 2002, American held 1,182 shares of Wesbanco common
stock. As of January 10, 2002, the trust department of Wesbanco Bank held 20,216
shares of American common stock. Wesbanco Bank has discretionary voting
authority over 7,906 of these shares. Except for the shares held by Wesbanco
Bank's trust department, neither Wesbanco nor any director, executive officer or
affiliate of Wesbanco owns shares of American common stock. Except as described
above in the summary and below, no director, officer or affiliate of American
has any special interest in the merger or is receiving any special consideration
or compensation as a result of the merger.



     Except as described below, no outstanding transactions between American or
Wesbanco and their respective affiliates, and any director, officer, or
principal shareholder of American or Wesbanco or their respective associates,
including any outstanding loans or trust relationships, will be affected by the
merger.


     Some officers and directors of American have interests in the merger that
are in addition to their interests as American shareholders generally. As
described below, some officers and directors of American will enter into
consulting agreements, employment agreements or severance agreements upon
completion of the merger.


     Paul W. Donahie, a director and the Vice Chairman of Wheeling National
Bank, will resign as an executive officer of Wheeling National Bank upon
completion of the merger. Mr. Donahie has entered into a consulting agreement
with Wesbanco that will become effective upon the completion of the merger
pursuant to which he will provide such services as Wesbanco may request from
time to time, and Wesbanco will pay Mr. Donahie $10,000 per month, plus
expenses, for his services. The consulting agreement will terminate 3 months
after the later to occur of the merger of American's subsidiaries or the date of
the data processing conversion for American. The consulting agreement provides
generally that Mr. Donahie may not engage in the banking business within a 50
mile radius of Wheeling, West Virginia during the term of the consulting
agreement and for a period of 1 year thereafter.


     Under American's severance plan, Mr. Donahie generally would be entitled to
a lump sum payment equal to 2.99 times his base salary following a change of
control of American if, following the change of control, he is terminated or
voluntarily resigns because he is not provided an employment opportunity with
the acquiring organization with comparable authority and the same salary as he
is then earning at American. Mr. Donahie has entered into a severance plan
clarification agreement with American and Wesbanco that provides
                                        21


generally that any lump sum payment that would be payable to Mr. Donahie by
American as a result of the change of control of American will equal $857,802 or
such lesser amount as may be required to avoid the excise tax imposed on excess
parachute payments as defined under Section 280G of the Internal Revenue Code.
If Mr. Donahie does not voluntarily terminate the consulting agreement referred
to in the preceding paragraph within 3 months from the date of the merger, in
lieu of any payment to which he may have been entitled under the severance plan,
he shall be paid a lump sum cash payment equal to $857,802 as a retention
incentive payment.

     Jeremy C. McCamic, American's Chief Executive Officer, will also resign
upon completion of the merger. Mr. McCamic has entered into a consulting
agreement with Wesbanco that will become effective upon completion of the merger
pursuant to which he will provide such services as Wesbanco may request from
time to time, and Wesbanco will pay Mr. McCamic $6,000 per month, plus expenses,
for his services. The consulting agreement also provides that Mr. McCamic will
be appointed to the Wesbanco Board of Directors and the Planning and
Acquisitions Committee thereof to serve until December 31, 2002. Mr. McCamic
will be paid additional attendance fees as a member of Wesbanco's Board of
Directors, but will not receive the quarterly retainer fee that would otherwise
be payable to a member of Wesbanco's Board of Directors. Mr. McCamic's
consulting agreement will terminate on the 6th anniversary of the merger and
provides generally that he may not engage in the banking business within a 50
mile radius of Wheeling, West Virginia during the term of the consulting
agreement.


     Under American's severance plan, Jeremy C. McCamic generally would be
entitled to an annuity that pays $10,000 per month for 12 years or the remainder
of his life, whichever is longer, following a change of control of American if,
following the change of control, he is terminated or voluntarily resigns because
he is not provided an opportunity with the acquiring organization with
comparable authority and the same compensation as he is then earning at
American. Mr. McCamic has entered into a severance plan clarification agreement
with American and Wesbanco that provides for the payment of a monthly annuity of
$9,000 for the remainder of Mr. McCamic's life with a minimum term certain of 12
years in full satisfaction of the benefits that may otherwise have been payable
to Mr. McCamic as a result of the change of control of American. The agreement
provides, however, that the present value of this annuity payment will equal
$969,970 or such lesser amount as may be required to avoid the excise tax
imposed on excess parachute payments as defined under Section 280G of the
Internal Revenue Code. In the event that an excise tax is imposed on Mr.
McCamic, Wesbanco has agreed to reimburse Mr. McCamic for the amount of such
excise tax. Mr. McCamic has assumed any income tax liability arising from the
excise tax reimbursement.



     John E. Wait, the President of Wheeling National Bank, has entered into an
employment agreement with Wesbanco Bank pursuant to which, following the merger,
he will be paid an annual base salary of not less than $185,000. The term of Mr.
Wait's employment agreement is 3 years, and will automatically renew for
successive 3 year terms unless written notice of termination is given by either
party at least 90 days prior to the relevant anniversary date of the agreement.
If the agreement terminates due to Mr. Wait's death, his surviving spouse or
estate will be paid an amount equal to 6 months of his then current base salary
(unless his death occurs within 6 months of the normal retirement date as
provided in Wesbanco Bank's pension plan or after such retirement date, in which
case his surviving spouse or estate will be paid an amount equal to 1 month of
his then current base salary). If Wesbanco Bank attempts to terminate the
employment agreement other than for "cause," Mr. Wait's death or by mutual
agreement, Mr. Wait will be entitled to receive an amount equal to the greater
of (i) 6 months base salary at his then current base rate or (ii) the base
salary he would have received if he was continually employed pursuant to the
agreement for the remainder of the then current term of the agreement.


     Under American's severance plan, Mr. Wait generally would be entitled to a
lump sum payment equal to 2.99 times his base salary following a change of
control of American if, following the change of control, he is terminated or
voluntarily resigns because he is not provided an employment opportunity with
the acquiring organization with comparable authority and the same salary as he
is then earning at American. Mr. Wait has entered into a severance plan
clarification agreement with American and Wesbanco that provides generally that
any lump sum payment that may be paid to him by American as a result of the
change of control of American will equal $500,994 or such lesser amount as may
be required to avoid the excise tax imposed on
                                        22


excess parachute payments as defined under Section 280G of the Internal Revenue
Code. If Mr. Wait does not voluntarily terminate his employment within 18 months
from the date of the merger, in lieu of any payment to which he may be entitled
under the severance plan, he shall be paid a lump sum cash payment equal to
$500,994 as a retention incentive payment.

     Brent E. Richmond, the President of American, has entered into an
employment agreement with Wesbanco Bank that is identical to the agreement with
Mr. Wait, except Mr. Richmond's annual base salary following the merger shall
not be less than $125,000. Under American's severance plan, Mr. Richmond
generally would be entitled to a lump sum payment equal to 2.99 times his base
salary following a change of control of American if, following the change of
control, he is terminated or voluntarily resigns because he is not provided an
employment opportunity with the acquiring organization with comparable authority
and the same salary as he is then earning at American. Mr. Richmond has entered
into a severance plan clarification agreement with American and Wesbanco that
provides generally that any lump sum payment that may be paid to him by American
as a result of the change of control of American will equal $517,919 or such
lesser amount as may be required to avoid the excise tax imposed on excess
parachute payments as defined under Section 280G of the Internal Revenue Code.
If Mr. Richmond does not voluntarily terminate his employment within 9 months
from the date of the merger, in lieu of any payment to which he may be entitled
under the severance plan, he shall be paid a lump sum cash payment equal to
$517,919 as a retention incentive payment.

     Patrick G. O'Brien, the Senior Vice President of Wheeling National Bank,
currently has an employment agreement with the Wheeling National Bank that
provides for, among other things, a payment to Mr. O'Brien in the event of a
change of control of Wheeling National Bank. Mr. O'Brien has entered into an
amendment to his employment agreement that will become effective upon
consummation of the merger and eliminates the change of control provision in
exchange for a lump sum payment equal to his annual salary as of the closing of
the merger. This payment will be made only if Mr. O'Brien does not voluntarily
terminate his employment for a period of 36 months after the merger, and the
payment will be in lieu of any payment to which he may have been entitled under
the change of control provision of his employment agreement.


     McCamic & McCamic provides legal services to American under a fixed
retainer engagement agreement between the parties. Jeremy C. McCamic, Jolyon W.
McCamic, Jeffery W. McCamic and Jay T. McCamic are partners in McCamic &
McCamic, each serves as a director of American and all are related. The
engagement letter has been amended, effective upon consummation of the merger,
to reduce the monthly retainer payable to McCamic & McCamic from $25,000 to
$6,000 for a term of 6 years following the merger. McCamic & McCamic will be
permitted to maintain hospitalization insurance for its employees through
Wesbanco's hospitalization insurance program upon payment of the premiums so
long as a member of the firm serves on the Wesbanco or an affiliate company's
Board of Directors.


EFFECTS OF THE MERGER: THE SURVIVING CORPORATION


     The merger will become effective at the time the Articles of Merger are
filed with, and the Certificate of Merger is issued by, the Secretary of State
of the State of West Virginia. At that time, the separate existence of American
will cease and AB Corporation will be the surviving corporation. The assets,
liabilities and capital of American will be merged into AB Corporation and those
assets, liabilities and capital will then constitute part of the assets,
liabilities and capital of AB Corporation. AB Corporation will continue to
operate under its Articles of Incorporation and Bylaws effective as of the day
of the merger, and the officers and directors of AB Corporation will continue as
the officers and directors of the surviving corporation. Following the
completion of the merger, Wheeling National Bank will be merged into Wesbanco
Bank and AB Corporation will be merged into Wesbanco. The Articles of
Incorporation and Bylaws of Wesbanco will be unaffected by the merger. The
tenure of the directors and officers of Wesbanco immediately prior to the merger
will be unaffected by the merger.



     Giving effect to the American merger, American would have, as of September
30, 2001, on a pro forma consolidated basis, constituted approximately 20.3% of
deposits, 21.7% of assets, and 14.2% of equity of Wesbanco, and its shareholders
would have held approximately 16.1% of the total outstanding shares of Wesbanco.
In addition, for the 9 months ended September 30, 2001, American would have
contributed


                                        23



approximately 14.3% of net interest income and 10.6% of net income to Wesbanco
on a pro forma consolidated basis.


     These percentages reflect the relative size of American as of September 30,
2001 and may change with the normal variances in the rates of growth for
deposits and loans for all Wesbanco affiliates. Additionally, it is contemplated
that Wesbanco may combine with other financial institutions in the future and
these mergers may affect the percentages shown above. Wesbanco is not presently
involved in any material merger transactions for which definitive agreements or
letters of intent have been executed.

MERGER OF SUBSIDIARY BANKS


     On the date of the merger, Wheeling National Bank will be merged with and
into Wesbanco Bank. At that time, the separate existence of Wheeling National
Bank will cease and Wesbanco Bank will be the surviving corporation. Wesbanco
Bank will consolidate some of the 21 currently existing offices of Wheeling
National Bank acquired by reason of the merger and 1 additional office that is
scheduled to open in January of 2002. It is anticipated that at least 5 offices
of the combined bank will be consolidated after the merger. In addition, 1
office of American will be sold to address a potential anti-trust issue.


GOVERNMENT APPROVALS


     Wesbanco and American have agreed to use their reasonable best efforts to
obtain all regulatory approvals required to consummate the acquisition, which
include approval from the Board of Governors of the Federal Reserve System and
the West Virginia Board of Banking and Financial Institutions. The approval of
the West Virginia Board of Banking and Financial Institutions was granted on
June 11, 2001 and the approval of the Federal Reserve was granted on January 7,
2002. The merger may not be consummated until 15 days after approval of the
Federal Reserve, during which time the United States Department of Justice
("DOJ") may challenge the merger on anti-trust grounds. If the DOJ were to
commence an anti-trust action, it would stay the effectiveness of Federal
Reserve approval of the merger unless a court specifically orders otherwise.
Neither American nor Wesbanco expects the merger to be challenged on
anti-competitive grounds. Wesbanco and American are not aware of any other
material governmental approvals or actions that are required prior to the
parties' consummation of the merger.



     Wesbanco's right to exercise its option under the Stock Option Agreement
also requires the prior approval of the Federal Reserve Board, to the extent
that the exercise of their options under such Stock Option Agreement would cause
Wesbanco to own more than 5% of the outstanding shares of American.


RIGHTS OF DISSENTING SHAREHOLDERS

     If you object to the merger and comply with Section 1701.85 of the Ohio
Revised Code, you are entitled to payment of the fair cash value of your shares.
The fair cash value of your shares is the amount a willing buyer who is under no
compulsion to buy would pay and a willing seller who is under no compulsion to
sell would be willing to accept. This amount will be determined as of the day
prior to the date of the Special Meeting without regard to any appreciation or
depreciation in anticipation of the merger. This value can never be greater than
the fair cash value you indicate in your written demand.


     The following is a brief summary of the steps you must take to perfect your
dissenters' rights under Ohio law. This summary does not purport to be complete
and is subject in all respects to the provisions of, and is qualified in its
entirety by reference to, the provisions of Section 1701.85 of the Ohio Revised
Code, which is reproduced in full as Annex E to this Proxy Statement.



     You Must be a Record Holder of American Common Stock on the Record Date.
You must be the record holder of American common stock on January 10, 2002.


     You Must Not Vote in Favor of the Merger.  You must not vote your shares in
favor of the merger. You are not required to vote against the merger, but if you
vote for the merger you will lose your right to exercise dissenters' rights.

                                        24



     You Must Make Written Demand for Fair Cash Value.  You must make written
demand on American, or the surviving corporation, for payment of the fair cash
value of your shares within 10 days after the vote is taken at the Special
Meeting. VOTING AGAINST THE MERGER DOES NOT CONSTITUTE THE DEMAND FOR PAYMENT
REQUIRED BY LAW. If you fail to make such written demand within the 10-day
period, you will be bound by the terms of the Merger Agreement. The written
demand must include your name, address, the number and class of dissenting
shares on which you seek relief and the amount you claim as the fair cash value
of those shares. The written demand should be addressed to American
Bancorporation, 1025 Main Street, Suite 800, Wheeling, West Virginia 26003. This
demand must be received by American on or before the 10th day after the vote at
the Special Meeting. Since actual receipt by American is required, if you choose
to mail your demand you might wish to consider using registered or certified
mail, return receipt requested.



     You Must Deliver Your Share Certificates to American for Legending if
American so requests. American may send you a request at the address listed on
your written demand asking you to deliver your share certificates for legending.
If American makes such a request, you must deliver your share certificates to
American within 15 days of American sending its request. American may then
endorse your certificates with a legend indicating that you demanded fair cash
value for the shares represented by the certificates. Once this endorsement is
made, American must promptly return your certificates. If a request is made and
you fail to deliver your certificates within this 15 day period, you will lose
your rights as a dissenter at American's option. To exercise this option,
American must send you notice of the termination of your dissenters' rights
within 20 days after the lapse of the 15 day period. If American exercises this
right you will lose your dissenters' rights unless a court for good cause
determines otherwise.



     You Must File a Petition in Court if You and American cannot Agree on the
Fair Cash Value of Your Shares.  If you and American cannot agree on a fair cash
value for your shares, you may, within 3 months after the service of your
written demand letter, file a complaint or join another complaint in the Court
of Common Pleas for Belmont County. Failure to file such a complaint or join
such a complaint within the 3-month period will result in termination of your
dissenters' rights. If such a suit is commenced, the court will determine if you
are entitled to be paid fair cash value and, if so, the court may appoint
appraisers to determine the fair cash value of your shares. If such a
determination is made, or if you and American agree upon a fair cash value, and
you follow the procedures in Section 1701.85 of the Ohio Revised Code, then 30
days after the fair cash value is determined or agreed upon American, or the
surviving corporation, will pay to you that value. When this payment is made you
must simultaneously surrender to American, or the surviving corporation, the
certificates representing your shares.


     Your Rights as a Dissenting Shareholder.  If you make such a demand and
follow the procedures of Section 1701.85 of the Ohio Revised Code, you shall
thereafter be entitled only to payment as a dissenting shareholder as provided
by law and you shall not be entitled to vote or to exercise any other rights of
a shareholder of American. Your right to be paid the fair cash value of your
shares will cease, and your status as a shareholder of American will be
restored, without prejudice to any corporate proceedings which may have been
taken during the interim, if any of the following events occurs:

     - Failure to comply with Section 1701.85, unless such failure is waived by
       American or the surviving corporation;

     - your demand is withdrawn with the consent of American or the surviving
       corporation;

     - the merger is abandoned or rescinded;

     - American is enjoined or prevented from carrying out the merger;

     - the American shareholders revoke the authority to effect the merger;

     - you and American cannot come to an agreement on the fair cash value of
       your dissenting shares and neither you nor American file suit in an
       appropriate Court of Common Pleas within the time period provided by
       Section 1701.85(B); or

     - a court of general civil jurisdiction determines that you are not
       entitled to relief as a dissenting shareholder.
                                        25



     To exercise your dissenters' rights, strict adherence to the provisions of
Ohio law is required. If you think you may desire to exercise your dissenters'
rights, you should carefully review the statutory provisions attached to this
Proxy Statement as Annex E. As in all legal matters, you would be well advised
to seek the guidance of an attorney.



     If you receive cash for the fair value of your shares of American common
stock, that cash will be subject to federal income taxes. The amount of gain or
loss and its character as ordinary or capital gain or loss will be determined in
accordance with Sections 302 and 1001 (and in certain cases, other provisions)
of the Internal Revenue Code. If you are contemplating the possible exercise of
dissenters' rights, you are urged to consult a tax advisor as to the federal
(and any applicable state and local) income tax consequences resulting from such
an election.



     American believes that the 1.1 shares of Wesbanco common stock to be issued
in the tax free merger in exchange for each share of American common stock is
fair and American does not anticipate a material number of shareholders will
exercise their dissenters' rights.


RESALE RESTRICTIONS

     The shares of Wesbanco common stock that you will receive in the merger
will be registered under the Securities Act of 1933. Under current law, if you
are not an affiliate of Wesbanco or American within the meaning of Rule 144 or
145 under the Securities Act of 1933, you may sell or transfer any shares of
Wesbanco common stock that you receive in the merger without need of further
registration under the Securities Act of 1933.

     If you are an affiliate of American before the merger or an affiliate of
Wesbanco after the merger, you may resell the shares of Wesbanco common stock
issued to you in the merger only:

     - in transactions permitted by Rules 144 and 145 under the Securities Act
       of 1933;

     - pursuant to an effective registration statement; or

     - in transactions exempt from registration.


     Generally, an executive officer, director or a principal shareholder or
other control person may be deemed to be an affiliate for these purposes. Other
shareholders would not be deemed to be affiliates. Rules 144 and 145, insofar as
relevant to shares acquired in the merger, impose restrictions on the manner in
which affiliates may make resales and also on the quantity of resales that such
affiliates, and others with whom they might act in concert, may make within any
3-month period.


     It is a condition to Wesbanco's obligation to consummate the merger that
American deliver to Wesbanco a schedule specifying the persons who may be deemed
to be affiliates of American and use its best efforts to cause each affiliate to
deliver to Wesbanco, prior to the closing of the merger, an affiliate's letter.
An affiliate's letter is a letter that states that the shares of Wesbanco common
stock issued to an affiliate pursuant to the merger will not be sold or
otherwise disposed of except:

     - in accordance with Rule 145 (where the affiliate has given Wesbanco
       evidence of compliance with the rule reasonably satisfactory to
       Wesbanco); or

     - pursuant to an effective registration statement under the Securities Act
       of 1933 unless such person has furnished to Wesbanco a no-action or
       interpretive letter from the SEC or an opinion of counsel reasonably
       satisfactory to Wesbanco that such transaction is exempt from or
       otherwise complies with the registration requirements of the Securities
       Act of 1933.

     An affiliate's letter also acknowledges that the certificates representing
the shares of Wesbanco common stock received by the affiliate may bear a legend
regarding these restrictions.

                                        26


ACCOUNTING TREATMENT


     The merger will be accounted for as a purchase by Wesbanco. The application
of this accounting treatment is shown in the unaudited pro forma condensed
combined financial information included on pages 9 through 11 of this Proxy
Statement.


CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER


     The merger is conditioned upon receipt at the closing of a legal opinion
from Kirkpatrick & Lockhart LLP, counsel to Wesbanco, as to the principal
federal income tax consequences expected to result from the merger. Wesbanco has
received a legal opinion from Kirkpatrick & Lockhart LLP to the effect that, as
of January 10, 2002 and based upon certain assumptions and representations, the
merger will have the federal income tax consequences described below. Neither
the opinion nor this summary addresses any tax considerations under foreign,
state or local laws, or any federal income tax considerations to shareholders
other than individual United States citizens or residents who hold their shares
of Wesbanco common stock or American common stock as a capital asset within the
meaning of Section 1221 of the Internal Revenue Code.



     No rulings have been or will be requested from the Internal Revenue Service
as to the federal income tax consequences of the merger. You should be aware
that the opinion of Kirkpatrick & Lockhart LLP is not binding on the Internal
Revenue Service and the Internal Revenue Service is not precluded from taking a
different position. Kirkpatrick & Lockhart LLP's opinion is based upon the
federal income tax laws as in effect on the date of the opinion and as those
laws are currently interpreted. There can be no assurance that future
legislation, regulations, administrative rulings or court decisions will not
adversely affect the accuracy of the statements contained herein or in the
opinion.



     The federal income tax consequences discussed below are conditioned upon,
and Kirkpatrick & Lockhart LLP's opinion is based upon, the accuracy, as of
January 10, 2002 and at, as of and after the time the merger becomes effective,
of certain representations made to Kirkpatrick & Lockhart LLP by officers of
Wesbanco and American and of certain assumptions.



     As of the date of this Proxy Statement, Wesbanco and American believe that
all of these representations and assumptions are now, and will be at, as of and
after the time the merger becomes effective, accurate. If either Wesbanco or
American learns before that time that the representations and the assumptions
are false or materially incorrect and that its counsel therefore believes that
the merger is unlikely to be treated as a tax free reorganization, then
additional shareholder approval will be obtained before consummation of the
merger.



     Subject to the limitations described above, the merger is expected to have
the following federal income tax consequences:


     - No gain or loss will be recognized by Wesbanco, American or AB
       Corporation as a result of the transactions contemplated in the Merger
       Agreement;

     - No gain or loss will be recognized by the shareholders of American as a
       result of their exchange of American common stock for Wesbanco common
       stock, except to the extent any shareholder receives cash in lieu of a
       fractional share or as a dissenting shareholder;


     - If a shareholder of American receives cash instead of a fractional share
       of Wesbanco common stock, the shareholder will be required to recognize a
       gain or loss, measured by the difference between (1) the amount of cash
       received instead of that fractional share, and (2) the portion of the tax
       basis of that shareholder's shares of American common stock allocable to
       that fractional share. This gain or loss will be a capital gain or loss
       and will be a long-term capital gain or loss if the share of American
       common stock exchanged for that fractional share of Wesbanco common stock
       was held for more than 1 year at the effective time of the merger and
       short-term capital gain or loss if the share of American common stock
       exchanged for that fractional share of Wesbanco common stock was held for
       1 year or less at the effective time of the merger;


     - A shareholder of American common stock will have a tax basis in the
       Wesbanco common stock received in the merger equal to (1) the tax basis
       of the American common stock surrendered by that
                                        27


       shareholder in the merger, less (2) any tax basis of the American common
       stock surrendered in the merger that is allocable to any fractional share
       of Wesbanco common stock for which cash is received by that shareholder;


     - The holding period of the Wesbanco common stock received in exchange for
       shares of American common stock in the merger will include the holding
       period for the shares of American common stock surrendered in the merger;
       and



     - A shareholder of American common stock who exercises dissenters' rights
       with respect to such shareholder's shares of American common stock and
       who receives payment for the stock in cash will generally recognize
       capital gain or loss, measured by the difference between (1) the
       shareholder's tax basis in the shares, and (2) the amount of cash
       received.


     The tax consequences of the merger may vary depending upon your particular
circumstances. YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISOR TO DETERMINE THE
PARTICULAR TAX CONSEQUENCES OF THE MERGER TO YOU. The foregoing discussion
addresses only the United States federal income tax effects of the merger. It
does not address the applicability and effect of any state, local or foreign
income, property, transfer and other tax laws.

                              THE MERGER AGREEMENT


     The following summary of the Merger Agreement is qualified in its entirety
by reference to the Merger Agreement and the First Amendment thereto, copies of
which are attached to this Proxy Statement as Annex A and Annex B, respectively.
You are urged to read these documents for a more complete description of the
merger.


THE MERGER

     After approval of the Merger Agreement by American shareholders, and the
satisfaction or waiver of other conditions to the merger, American will be
merged with and into AB Corporation, with AB Corporation continuing as the
surviving corporation. The Articles of Incorporation and Bylaws of AB
Corporation immediately prior to the merger will constitute the Articles of
Incorporation and Bylaws of the surviving corporation.

CONVERSION OF SECURITIES

     In the merger, each share of American common stock issued and outstanding
immediately prior to the time the merger becomes effective (subject to certain
exceptions) will be exchanged for and become, without action on the part of the
shareholder, the right to receive 1.1 shares of Wesbanco common stock.

     Shares of American common stock held by American in its treasury or
beneficially owned by AB Corporation or Wesbanco (other than in a fiduciary
capacity by them for others) will not be exchanged for shares of Wesbanco common
stock in the merger. Instead, these shares will be canceled and retired. Shares
of American common stock as to which dissenters' rights are properly exercised
also will not be exchanged for shares of Wesbanco common stock in the merger.

     No fractional shares of Wesbanco common stock will be issued in the merger.
Instead, cash will be paid in lieu of fractional shares in an amount based on a
value of $22.31 per whole share of Wesbanco common stock.

     Promptly after the merger becomes effective, Fifth Third Bank, Wesbanco's
stock transfer agent, will mail transmittal forms and exchange instructions to
each holder of record of American common stock to be used to exchange shares of
American common stock for shares of Wesbanco common stock. These transmittal
letters will be accompanied by instructions specifying other details of the
exchange. American shareholders should not send in their certificates until they
receive a transmittal form and instructions.

                                        28


     After the merger becomes effective, each certificate evidencing shares of
American common stock will be deemed to evidence only the right to receive:

     - the number of shares of Wesbanco common stock that the holder is entitled
       to receive by virtue of the merger; and

     - the cash payment for any fractional share of Wesbanco common stock.

     The holder of an unexchanged certificate will not receive any dividend or
other distribution payable by Wesbanco until the certificate has been exchanged
or, in the case of a lost certificate, until a lost certificate agreement and
lost certificate bond have been posted.

REPRESENTATIONS AND WARRANTIES

     The Merger Agreement contains various customary representations and

     - the absence of any material increase in expenditures for any bonus,

       personnel policies of American or its subsidiaries;

     - the absence of any material loans or advances by American or its
       subsidiaries other than in the ordinary course of business;

other things:

     - the registration of Wesbanco as a bank holding company under the Bank
       Holding Company Act of 1956;

     The Merger Agreement may be terminated at any time prior to the closing of

     - by mutual consent of American and Wesbanco;

     - by either American or Wesbanco if any of the conditions to such party's

       the date the merger is to close and such conditions have not been waived
       by the party adversely affected thereby;

     In the event of any termination of the Merger Agreement by either American
or Wesbanco as provided above, all further obligations of American and Wesbanco
under the Merger Agreement, except with respect to specified matters, including
without limitation those related to confidentiality and expenses, will terminate
without further liability of the parties.

     Whether or not the merger is consummated, all legal and accounting fees,
and other costs and expenses incurred in connection with the Merger Agreement
and the transactions contemplated therein, will be paid by the party incurring

AMENDMENT OR WAIVER

     The provisions of the Merger Agreement may be waived at any time by the
party which is, or the shareholders of which are, entitled to the benefit of
those provisions, by action taken by the Board of Directors of that party. Any
of the terms of the Merger Agreement may be amended or modified in writing
before or after the Special Meeting of American shareholders at any time prior
to the closing of the merger. The conversion ratio and any other material terms
of the merger will not be amended after the Special Meeting of American
shareholders unless the amended terms are resubmitted to the shareholders of
American for approval.

     The Merger Agreement may not be modified or terminated except by a written
statement signed by the party against which the enforcement of the modification
or termination is sought.

                             STOCK OPTION AGREEMENT

     In connection with the Merger Agreement, American granted Wesbanco an
option to purchase up to 622,805 shares of American common stock at a price of
$18.00 per share pursuant to the Stock Option Agreement, dated February 22,
2001, a copy of which is attached hereto as Annex C. The Stock Option Agreement
could discourage other companies from trying or proposing to combine with
American before the completion of the merger.
                                        35


     If American issues or agrees to issue any shares of American common stock
(other than as permitted by the Merger Agreement) at a price less than $18.00
per share, the exercise price per share under the option agreement will be
reduced to that lower price. If any change in American common stock occurs by
reason of stock dividends, split-ups, mergers, recapitalizations, combinations,
exchanges of shares or the like, the type and number of shares subject to the
option, and the purchase price per share, will be adjusted appropriately. Also,
if American issues additional shares of its common stock after the date of the
option agreement (other than pursuant to the option agreement), the number of
shares of American common stock subject to the option shall be adjusted so that
it is exercisable for 19.9% of the number of shares of American common stock
issued and outstanding after such issuance.


     Wesbanco may exercise the option only if 1 of the following events (each, a
"Purchase Event") occurs after the date of execution of the option agreement:


     (i) any person (other than Wesbanco, an affiliate thereof, American or
         Wheeling National Bank) has commenced a bona fide tender or exchange
         offer to purchase shares of American common stock such that upon
         consummation of such offer such person would own or control 15% or more
         of the outstanding shares of American common stock;

     (ii) any person (other than American or Wheeling National Bank), other than
          in connection with a transaction to which Wesbanco has given its prior
          written consent, has filed an application or notice with any federal
          or state regulatory agency for clearance or approval, to (x) merge,
          consolidate or enter into any similar transaction with American or
          Wheeling National Bank, (y) purchase, lease or otherwise acquire all
          or substantially all of the assets of American or Wheeling National
          Bank, or (z) purchase or otherwise acquire (including by way of
          merger, consolidation, share exchange or any similar transaction)
          securities representing 51% or more of the voting power of American or
          Wheeling National Bank;

     (iii) any person (other than Wesbanco, an affiliate thereof, American,
           Wheeling National Bank, individually or in a fiduciary capacity, or
           any Wesbanco subsidiary individually or in a fiduciary capacity) has
           acquired beneficial ownership or the right to acquire beneficial
           ownership of 15% or more of the outstanding shares of American common
           stock;

     (iv) any person (other than American or Wheeling National Bank) shall have
          made a bona fide proposal to American by public announcement or
          written communication that is or becomes the subject of public
          disclosure to (x) acquire American or Wheeling National Bank by
          merger, consolidation, purchase of all or substantially all of its
          assets or any other similar transaction, or (y) make an offer
          described in paragraph (i) above; or

     (v) American shall have willfully breached Section 8.21(d) of the Merger
         Agreement and that breach entitles Wesbanco to terminate the Merger
         Agreement and such breach has not been cured prior to the date on which
         Wesbanco shall notify American of its intent to exercise the option.


     The option may be exercised in whole or in part, at 1 or more closings, at
any time (or from time to time) if a Purchase Event has occurred, continues to
occur, and the option agreement has not terminated. The option agreement
provides that to the extent that it shall have not been exercised, the option
shall terminate:


          (a) on the effective date of the merger;

          (b) upon the termination of the Merger Agreement in accordance with
     its provisions (other than a termination resulting from a willful breach by
     American of Section 8.21(d) of the Merger Agreement or, following the
     occurrence of a Purchase Event, the failure of American's shareholders to
     approve the Merger Agreement by the vote required under applicable law); or


          (c) 6 months after termination of the Merger Agreement due to a
     willful breach by American of Section 8.21(d) of the Merger Agreement or,
     following the occurrence of a Purchase Event, failure of American's
     shareholders to approve the Merger Agreement by the vote required under
     applicable law.


     If at any time during the 18 months immediately following the first
purchase of shares of American common stock pursuant to the option, Wesbanco
desires to sell, assign, transfer or otherwise dispose of all or

                                        36


any of the shares of American common stock acquired by it pursuant to the
option, it will offer American an opportunity to purchase such shares on the
same terms and conditions and at the same price at which Wesbanco is proposing
to transfer such shares to a third party, subject to the provisions and
exceptions set forth in the option agreement.


     Prior to the expiration of the option according to the terms of the option
agreement, at the request of Wesbanco, American shall repurchase the option from
Wesbanco upon the consummation of 1 of the following Purchase Events:


     (i) the consummation of a merger, consolidation, purchase, lease or
         acquisition of all or substantially all of the assets of American,
         purchase or other acquisition of securities representing 51% or more of
         the voting power of American or any subsidiary of American, or

     (ii) a willful breach under Section 8.21(d) of the Merger Agreement that
          entitles Wesbanco to terminate such agreement.

     American shall repurchase the option from Wesbanco at a price equal to the
difference between the market/offer price (as defined in the option agreement)
for shares of American common stock and the option price, multiplied by the
number of shares for which the option being surrendered hereunder may then be
exercised but only if the market/offer price is greater than the option price.

     The option agreement provides that at the request of Wesbanco, American
will file a registration statement in order to permit the sale or other
disposition of the shares of American common stock that have been acquired
pursuant to the option with the intended method of sale or other disposition
requested by Wesbanco. American will use its best efforts to cause the
registration statement first to become effective and then to remain effective
for a period not in excess of 270 days from the day the registration statement
first becomes effective as may be reasonably necessary to conduct such sales or
other dispositions.

                       COMPARATIVE RIGHTS OF SHAREHOLDERS

DESCRIPTION OF WESBANCO CAPITAL STOCK

     The authorized capital stock of Wesbanco consists of 50,000,000 shares of
common stock, par value $2.0833 per share, and 1,000,000 shares of preferred
stock without par value. As of September 30, 2001, there were approximately
17,943,535 shares of Wesbanco common stock outstanding, held of record by
approximately 5,179 holders.


     As of the date of this Proxy Statement, there were no shares of preferred
stock outstanding. Shares of preferred stock may be issued in one or more
classes or series with such preferences, voting rights, full or limited, but not
to exceed one vote per share, conversion rights and other special rights as the
Wesbanco Board of Directors may fix in the resolution providing for the issuance
of the shares. The issuance of shares of preferred stock could affect the
relative rights of the Wesbanco common stock.


     Depending upon the exact terms, limitations and relative rights and
preferences, if any, of the shares of preferred stock as determined by the Board
of Directors at the time of issuance, the holders of preferred stock may be
entitled to a higher dividend rate than that paid on the Wesbanco common stock,
a prior claim on funds available for the payment of dividends, a fixed
preferential payment in the event of liquidation and dissolution of Wesbanco,
redemption rights, rights to convert their preferred stock into shares of
Wesbanco common stock, and voting rights which would tend to dilute the voting
control of Wesbanco by the holders of Wesbanco common stock.

     Subject to the above limitations, in the event of any liquidation,
dissolution or winding up of Wesbanco, and subject to the application of state
and federal laws, holders of Wesbanco common stock are entitled to share ratably
in the assets available for distribution to stockholders remaining after payment
of Wesbanco's obligations.

     Each share of Wesbanco common stock is entitled to one vote, and to
cumulate votes in the election of directors. No holder of shares of Wesbanco
common stock has any preemptive right to subscribe for or
                                        37



purchase any other securities of Wesbanco, and there are no conversion rights or
redemption or sinking fund provisions applicable to Wesbanco common stock.
However, Wesbanco elects directors on a staggered basis by class with terms of 3
years. This provision of its Articles of Incorporation requires a super majority
vote of its shareholders to change.


COMPARISON OF RIGHTS OF WESBANCO AND AMERICAN SHAREHOLDERS

     The rights of the American shareholders and the Wesbanco shareholders are
governed by the respective Articles of Incorporation and Bylaws of each
corporation and Ohio and West Virginia law, respectively. In many respects, the
rights of American shareholders and Wesbanco shareholders are similar. For
example:

     - Holders of common stock of each corporation are entitled to one vote for
       each share of common stock and to receive pro rata any assets distributed
       to shareholders upon liquidation.

     - Neither corporation's shareholders have preemptive rights.

     - The shareholders of both corporations have the right under Ohio and West
       Virginia law to dissent from certain corporate transactions and to elect
       dissenters' rights.

     - The shareholders of both corporations either have or may invoke
       cumulative voting in the election of directors.

     - The shareholders of both corporations elect directors for staggered terms
       of three years, with no more than one-third of the directors being
       elected in any one year.

DIFFERENCES IN RIGHTS

     There are, however, differences between the rights of American shareholders
and Wesbanco shareholders. The material differences are summarized in the table

                              or 50% or more.


ANTI-TAKEOVER PROVISIONS

     Some of the provisions of Wesbanco's Articles of Incorporation and Bylaws
discussed above may constitute defensive measures in that they may discourage or
deter a third party from attempting to acquire control of Wesbanco. They are
designed, in part, to discourage and to insulate the corporation against hostile
takeover efforts, which the Wesbanco Board of Directors might determine are not
in the best interests of Wesbanco and its shareholders. The provisions are
designed as reasonable precautions to protect against, and to assure the
opportunity to assess and evaluate, such confrontations.


     The classification of the Board of Directors makes it more difficult to
change directors since they are elected for terms of 3 years rather than 1 year,
and at least 2 annual meetings instead of 1 are required to change a majority of
the Board of Directors. Furthermore, due to the smaller number of directors to
be elected


                                        41


at each annual meeting, holders of a minority of the voting stock may be in a
less favorable position to elect directors through the use of cumulative voting.

     The super majority provision makes it more difficult for shareholders to
effect changes in the classification of directors.

     The ability of the Board of Directors to issue additional shares of common
and preferred stock also permits the Board of Directors to authorize issuances
of stock which may be dilutive and, in the case of preferred stock, which may
affect the substantive rights of shareholders without requiring an additional
shareholder vote.

     Collectively, the provisions may be beneficial to management in a hostile
takeover attempt, making it more difficult to effect changes, and at the same
time, adversely affecting shareholders who might wish to participate in such a
takeover attempt.

     The foregoing identification of specific differences between the rights of
Wesbanco and American shareholders is not intended to indicate that other
equally or more significant differences do not exist. This summary is qualified
in its entirety by reference to the West Virginia Corporation Act and the Ohio
Revised Code and the Articles of Incorporation and Bylaws of Wesbanco and
American.

                           FORWARD LOOKING STATEMENTS



     Wesbanco and American have each made forward looking statements in this
document and in other documents to which this document refers. These statements
are subject to risks and uncertainties. These statements are based on the
beliefs and assumptions of the management of Wesbanco and American and on
information currently available to them or, in the case of information that
appears under the heading "The Merger" beginning on page 13, information that
was available to management of Wesbanco and American as of the date of the
Merger Agreement. Forward looking statements include, but are not limited to,
the information concerning possible or assumed future results of operations of
Wesbanco. You can identify these forward looking statements by the words
"believes," "contemplates," "expects," "may," "will," "should," "would,"
"anticipates," and similar expressions. Discussions of strategy are also
forward-looking statements.



     We caution you that these statements are not guarantees of future
performance and involve risks and uncertainties that we cannot predict. In
addition, many of these forward looking statements are based on assumptions
about the future that may prove to be inaccurate. Accordingly, actual results
may differ materially from those expressed in the forward-looking statements.



     Any statements in this document about the anticipated effect of the merger
and Wesbanco's performance in future periods are subject to risks relating to,
among other things, the following:



     - expected cost savings from the merger may not be fully realized or
      realized within the expected time frame;



     - the loss of deposits, customers or revenues following the merger may be
      greater than expected;



     - competitive pressures among depository and other financial institutions
      may increase significantly;



     - costs or difficulties related to the integration of the businesses of
      Wesbanco and American may be greater than expected;



     - changes in the interest rate environment may reduce margins or the
      volumes or values of loans made or held;



     - general economic or business conditions, either nationally or in the
      states or regions in which Wesbanco and American do business, may be worse
      than expected, resulting in, among other things, a deterioration in credit
      quality or a reduced demand for credit;



     - legislative or regulatory changes, including changes in accounting
      standards, may adversely affect the business in which Wesbanco and
      American are engaged; and



     - competitors of Wesbanco and American may develop products that enable
      those competitors to compete more successfully than Wesbanco or American.


                                        43



     Both Wesbanco and American believe the forward-looking statements about the
merged company are reasonable. However, American's shareholders should not place
undue reliance on them. Forward looking statements are not guarantees of
performance. They involve risks, uncertainties and assumptions. The future
results and shareholder values of Wesbanco following the merger may differ
materially from those expressed or implied in these forward looking statements.
Many of the factors that will determine these results and values are beyond
Wesbanco's and American's ability to control or predict.



     We expressly qualify all subsequent written and oral forward looking
statements concerning the merger or other matters addressed in this document and
attributable to Wesbanco or American or any person acting on their behalf by the
foregoing cautionary statements. Neither Wesbanco nor American undertakes any
obligation to release publicly any revisions to these forward-looking statements
to reflect events or circumstances after the date of this document or to reflect
the occurrence of unanticipated events.


                                 LEGAL MATTERS


     Certain matters will be passed upon for Wesbanco by its counsel, Phillips,

                    BYLAWS; BOARD OF DIRECTORS AND OFFICERS

     4.1  AB.  The Articles of Incorporation of AB, as organized, shall
constitute the Articles of Incorporation of the Surviving Corporation. The
Bylaws of AB as in effect on the Effective Date shall constitute the Bylaws of
the Surviving Corporation. The directors and officers of AB on the Effective

position of director for which the Board shall solicit proxies at its next
annual meeting of shareholders until each has served at least a full three year
term. During his term on the Board, the said Jeremy C. McCamic shall also be
appointed to the Executive Committee. Wesbanco will take such action under its

the Agreement to its shareholders in accordance with the Ohio Revised Code

                                   SECTION 6

                              CONVERSION OF SHARES

     6.1  Conversion, Exchange Ratio and Option.  The manner of converting or
exchanging the shares of American, AB and the Subsidiary shall be as follows:

          (a) Each share of American Common Stock issued and outstanding
     immediately prior to the Effective Time, except shares of American Common
     Stock issued and held in treasury of American or beneficially owned by AB
     or Wesbanco, other than in a fiduciary capacity by Wesbanco for others, and
     shares as to which dissenters' rights are exercised pursuant to Section
     1701.85 of the ORC, shall by virtue of the Merger and at the Effective Time
     of the Merger be exchanged for and become, without action on the part of
     the holder thereof, 1.1 shares of Wesbanco Common Stock having equal rights
     and privileges with respect to all other common stock of Wesbanco issued
     and outstanding as of the Effective Time of the Merger.

          (b) No fractional shares of Wesbanco Common Stock will be issued in
     connection with the Merger. In lieu thereof each stockholder of American
     otherwise entitled to a fractional share of Wesbanco will receive cash
     therefore in an amount based on a value of $22.31 per whole share of
     Wesbanco stock, at the time of the exchange.

          (c) In the event of any change in Wesbanco Common Stock by reason of
     stock dividends, split-ups, mergers, recapitalizations, combinations,
     exchanges of shares (by Wesbanco shareholders) or the like, the type and
     number of shares to be issued pursuant to Section 6.1(a) hereof shall be
     adjusted proportionately.

          (d) Each share of the common stock of the Subsidiary issued and
     outstanding immediately prior to the Effective Date of the Bank Merger
     shall, on the Effective Date, be converted into an equal number of issued
     and outstanding shares of the Surviving Bank Corporation.

     6.2  Shares Owned by American, Wesbanco or AB.  Each share of American
Common Stock issued and held in the treasury of American or beneficially owned
by Wesbanco or AB, other than in a fiduciary capacity, at the Effective Time of
the Merger shall be canceled and no cash or other property shall be delivered in
exchange therefore.

     6.3  Exchange for Stock.  On and after the Effective Date of the Merger,
each holder of American Common Stock, upon presentation and surrender of a
certificate or certificates therefore to Fifth Third Bank (the "Exchange
Agent"), shall be entitled to receive in exchange therefore (i) a certificate or
certificates representing the number of shares of Wesbanco Common Stock to which
he or she is entitled as provided herein, and payment in cash for any fractional
share of common stock which he is entitled to receive, without interest. Until
so presented and surrendered in exchange for a certificate representing Wesbanco
Common Stock, each certificate which represented issued and outstanding shares
of American Common Stock immediately prior to the Effective Time shall be deemed
for all purposes to evidence ownership of the number of shares of Wesbanco
Common Stock into which such shares of stock have been converted pursuant to the
Merger. Until surrender of such certificates in exchange for certificates
representing the converted stock, the holder thereof shall not receive any
dividend or other distribution payable to holders of shares of such stock;
provided, however, that upon surrender of such certificates representing such
converted stock in exchange for certificates representing the stock into which
it has been converted, there shall be paid to the record holder of the
certificate representing Wesbanco Common Stock issued upon such surrender, the
amount of dividends or other distributions (without interest) which theretofore
became payable with respect to the number of shares of such stock represented by
the certificate or certificates to be issued upon such surrender, together with
payment of cash for any fractional share to which such holder is entitled, as
above set forth.

     6.4  Closing of Stock Transfer Books.  On the Effective Date, the stock
transfer books of American shall be closed, and no shares of American Common
Stock outstanding the day prior to the Effective Date shall thereafter be
transferred.

                                       A-5


     6.5  Directors' Qualifying Shares.  Immediately upon completion of the
mergers provided for above, the newly elected Directors of Bank shall maintain
at least the minimum number of shares of Wesbanco Common Stock as are required
to be held as directors' qualifying shares under applicable law for membership
on the Board of Directors of Bank.

                                   SECTION 7

                               DISSENTERS RIGHTS

     7.1  Subject to the rights of Wesbanco and American, as permitted by
Section 12.1(i) of the Agreement, to terminate the Agreement and abandon the
Merger in the event that the number of Objecting Shares (as hereinafter defined)
shall exceed 10% of the shares of American issued and outstanding on the date of
the shareholders' meeting described in Sections 5.1 and 14.1 of this Agreement
and entitled to vote on this Agreement (hereinafter, "Voting Shares"), the
rights and remedies of a dissenting shareholder under the ORC shall be afforded
to any shareholder of American who objects to the Merger in a timely manner in
accordance with the ORC, and who takes the necessary steps in a timely manner in
accordance with the ORC to perfect such shareholder's rights as a dissenting
shareholder (such shareholder being hereafter referred to as a "Dissenting
Shareholder"). The Surviving Corporation will make such payments as are required
to be made to Dissenting Shareholders in the exercise of such rights. The term
"Objecting Shares" shall mean the shares of those holders of American Common
Stock who shall file written demand for payment of the fair cash value with

             REPRESENTATIONS, WARRANTIES AND COVENANTS OF AMERICAN

     American represents and warrants to and covenants with Wesbanco and AB, in
its own right and with respect to its wholly owned Subsidiary, that:

     8.1  Organization and Qualification of American.  American is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Ohio and has the full corporate power and authority to own all of its
properties and assets and to carry on its business as it is now being conducted,
and neither the ownership of its property nor the conduct of its business
requires it or its Subsidiary to be qualified to do business in any other
jurisdiction, except where the failure to be so qualified, considering all such
cases in the aggregate, does not involve a material risk to the business,
properties, financial position or results of operations of American and its
Subsidiary taken as a whole.

     8.2  Authorization of Agreement.  The Board of Directors of American has
authorized the execution of this Agreement as set forth herein, and subject to
the approval of this Agreement by the shareholders of American as provided in
the Articles of Incorporation and Bylaws of American and applicable Ohio law,
American has the corporate power and is duly authorized to merge with AB
pursuant to this Agreement, and this Agreement is a valid and binding agreement
of American enforceable in accordance with its terms, except as enforceability
may be subject to applicable bankruptcy, insolvency, moratorium or other similar
laws affecting the enforcement of creditors' rights generally and to any
equitable principles limiting the right to obtain specific performance of
certain obligations thereunder.

     8.3  No Violation of Other Instruments.  Subject to obtaining any required
consent (which consents will be obtained by American prior to Closing), the
execution and delivery of this Agreement do not, and the consummation of the
Merger and the Bank Merger and the transactions contemplated hereby will not,
violate any provisions of American's Articles of Incorporation or Bylaws, or any
provision of, or result in the acceleration of any obligation under, any
material mortgage, deed of trust, note, lien, lease, franchise, license,

                                       A-6


permit, agreement, instrument, law, order, arbitration award, judgment or decree
or in the termination of any material license, franchise, lease or permit to
which American or the Subsidiary are a party or by which they are bound. After
the approval of this Agreement by the shareholders of the common stock of
American, the Board of Directors and the shareholders of American will have
taken all corporate action required by applicable law, the Articles of
Incorporation of American, its Bylaws or otherwise to authorize the execution
and delivery of this Agreement and to authorize the Merger of American and AB
pursuant to this Agreement.

     concerning the business and affairs of American, its Subsidiary and their

     approvals, including, but not limited to, an application to the Federal
     Reserve Board and the West Virginia Department of Banking for prior

assets which it owns, and neither the ownership of its property nor the conduct
of its business requires it, or any of its subsidiaries, to be qualified to do
business in any other jurisdiction except where the failure to be so qualified,
considering all such cases in the aggregate, does not involve a material risk to
the business, properties, financial position or results of operations of
Wesbanco and its subsidiaries taken as a whole. Each of Wesbanco's subsidiaries
("Wesbanco Subs"), other than AB, is a West Virginia, Ohio or Delaware
corporation, duly organized and validly existing in good standing under the laws

power and authority to carry on its business as it is now being conducted and to
own the properties and assets which it owns. All issued and outstanding shares
of stock of AB and the Wesbanco Subs are held, beneficially and of record, by
Wesbanco and have been or, as to AB, on the date of its execution hereof, will
have been, fully paid, were validly issued and are nonassessable. There are no
options, warrants to purchase or contracts to issue, or contracts or any other
rights entitling anyone to acquire, any other stock of AB or any of the Wesbanco
Subs or securities convertible into shares of stock of AB or any of the Wesbanco
Subs.

limiting the right to obtain specific performance of certain obligations
thereunder. Upon execution hereof by AB and Bank and subject to the approval
hereof by Wesbanco as their sole shareholder, AB and Bank have the corporate
power to execute and deliver this Agreement and have taken all action required
by law, their Articles of Incorporation, their Bylaws or otherwise to authorize
and approve such execution and delivery, the performance of the Agreement, the
Merger, the Bank Merger and the consummation of the transactions contemplated

        within the meaning of Section 368(a)(1) of the Internal Revenue Code of

     instituted before any court, governmental agency or legislative body to
     enjoin, restrain or prohibit, or to obtain substantial damages with respect
     to, the Agreement or the consummation of the transactions contemplated
     hereby, which, in the reasonable judgment of Wesbanco or American would
     make it inadvisable to consummate such transactions (it being understood
     and agreed that a written request by governmental authorities for
     information with respect to the Merger or the Bank Merger may not be deemed
     by either party to be a

                                       A-21


     threat of material litigation or proceeding, regardless of whether such
     request is received before or after execution of the Agreement).

     deems to be materially disadvantageous or burdensome.

     Effective Date with the same effect as though made on and as of such date,
     except for representations and warranties expressly made only as of a
     particular date and except for changes which have been consented to by
     Wesbanco or which are not, in the aggregate, material and adverse, to the
     financial condition, businesses, properties or operations of American and

     transactions contemplated or permitted by the Agreement; and American shall
     have performed in all material respects all of its obligations and
     agreements hereunder theretofore to be performed by it; and Wesbanco and AB
     shall have received on the Effective Date an appropriate certificate (in
     affidavit form) dated the Effective Date and executed on behalf of American

     that such officers have no knowledge of the nonfulfillment of the foregoing
     condition;

        corporate power and authority to own all of its properties and assets
        and to carry on its business as it is now being conducted, and neither
        the ownership of its property nor the conduct of its business requires
        it, or its Subsidiary, to be qualified to do business in any other
        jurisdiction except where the failure to be so qualified, considering
        all such cases in the aggregate, does not involve a material risk to the
        business, properties, financial position or results of operations of
        American and its Subsidiary, taken as a whole.

             (ii) American has the full corporate power to execute and deliver
        the Agreement. All corporate action of American required to duly
        authorize the Agreement and the actions contemplated thereby has been
        taken, and the Agreement is valid and binding on American in accordance
        with its terms, subject, as to the enforcement of remedies, to
        applicable bankruptcy, insolvency, reorganization, fraudulent
        conveyance, receivership, moratorium, or other similar laws affecting
        the enforcement of creditors' rights generally from time to time in
        effect, whether state or federal; subject to application of the public
        policy of the State of West Virginia; and subject to any equitable
        principles limiting the right to obtain specific performance of certain
        obligations thereunder, whether such enforcement is considered in a
        proceeding in equity or at law.

             (iii) All shares of common stock of American issued and outstanding
        as of the Effective Date are duly authorized, validly issued, fully paid
        and nonassessable.

             (iv) The consummation of the Merger and the Bank Merger
        contemplated by the Agreement will not violate any provision of
        American's or the Subsidiary's Articles of Incorporation or Bylaws, or
        violate any provision of, or result in the acceleration of any material
        obligation under, any material mortgage, loan agreement, order,
        judgment, law or decree known to such counsel to which American is a
        party or by which it is bound and will not violate or conflict with any
        other material restriction of any kind or character known to such
        counsel to which American is subject, which would have a materially
        adverse effect on the assets, business or operations of American, taken
        as a whole.

        corporation.

             (vi) To the best of such counsel's knowledge, as of the date hereof

        threatened.

     all persons who may be deemed to be "affiliates" of American under Rule 145

     pending against American or its Subsidiary or the officers or directors of
     American or its Subsidiary in their capacity as such, any suit, action or

     date, except for representations and warranties expressly made only as of a
     particular date and except for changes which have been consented to by
     American or which are not in the aggregate material and adverse to the

        Virginia and have the full corporate power and authority to own all of
        their properties and assets and to carry on their businesses as they are
        now being conducted, and neither the ownership of their property nor the
        conduct of their businesses require them, or any of their subsidiaries,
        to be qualified to do business in any other jurisdiction except where

        Incorporation or Bylaws, or violate any provision of, or result in the
        acceleration of any material obligation under, any material mortgage,
        loan agreement, order, judgment, law or decree known to such counsel to
        which Wesbanco, AB or Bank are a party or by which they are bound, and
        will not violate or conflict with any other material restriction of any
        kind or character known to such counsel to which Wesbanco, AB or Bank

     American, if successful,

                                       A-24


     would have a material adverse effect on the financial condition or

of submitting this Agreement to its shareholders for their consideration and
approval and will send to its shareholders for purposes of such meeting a Proxy
Statement which will not contain any untrue statement of a material fact with
respect to American or omit to state a material fact with respect to American
required to be stated therein or necessary to make the statements contained
therein, in light of the circumstances under which they were made, not
misleading, and which otherwise materially complies as to form with all
applicable laws, rules and regulations.

substance satisfactory to the other party and its counsel, stating that, to the
best of their knowledge and belief, all of the facts with respect to either
Wesbanco or American, as the case may be, set forth in the Registration
Statement, are true and correct in all material respects, and that the
Registration Statement does not omit any material fact necessary to make the
facts stated therein with respect to such party not misleading in light of the
circumstances under which they were made.

                  FIRST AMENDMENT TO AGREEMENT AND PLAN OF MERGER

     THIS FIRST AMENDMENT AGREEMENT (hereinafter called "Agreement"), made and
entered into as of the 5th day of November, 2001, by and between WESBANCO, INC.,
a West Virginia corporation, with its principal place of business located at
Bank Plaza, Wheeling, West Virginia (hereinafter called "Wesbanco"), party of
the first part, AMERICAN BANCORPORATION, an Ohio corporation, with its principal
place of business located at 1025 Main Street, Wheeling, West Virginia, 26003,
(hereinafter called "American") party of the second part, AB CORPORATION
(hereinafter called "AB"), a corporation to be formed under the laws of the
State of West Virginia by Wesbanco as its wholly-owned subsidiary solely for the
purpose of effecting the acquisition contemplated by this Agreement, party of
the third part, (effective as of its organization and execution of this
Agreement) and WESBANCO BANK, INC., a West Virginia banking corporation, with
its principal place of business located at One Bank Plaza, Wheeling, West
Virginia, 26003, party of the fourth part (hereinafter called "Bank").

     WHEREAS, the parties hereto heretofore executed a certain Agreement and
Plan of Merger dated the 22nd day of February, 2001 (hereinafter called "Merger
Agreement") and the parties desire to make certain amendments to the terms and
conditions of said Merger Agreement, all as hereinafter set forth.

     NOW, THEREFORE, for and in consideration of the mutual promises and
covenants hereinafter set forth, and in accordance with the provisions of
applicable law, and intending to be legally bound hereby, the parties hereto do
hereby agree as follows:

     1. The parties hereby agree that the capitalized terms not herein
specifically defined shall have the meanings ascribed to them in the Merger
Agreement.

     2. Section 4.3 of said Merger Agreement is hereby deleted in its entirety
and the following Section 4.3 is substituted in its place:

          4.3  Bank Directors.  Wesbanco covenants and agrees that as of the
     Effective Date it will appoint, as additional directors of Bank, Jack A.
     Cartner, Jolyon W. McCamic, and Jeffrey W. McCamic, specifically waiving
     for such limited term, its age 70 provision of its Bylaws. Such individuals
     shall serve until December 31, 2002, at which time the terms for Jack A.
     Cartner and Jolyon W. McCamic shall expire and they will resign from the
     Bank Board. Jeffrey W. McCamic shall continue as a member of the Bank Board
     and shall serve until his successor shall have been duly elected and
     qualified.

     3. Section 4.4 of said Merger Agreement is hereby deleted in its entirety
and the following Section 4.4 is substituted in its place:

          4.4  Wesbanco Directors.  Wesbanco covenants and agrees that as of the
     Effective Date it will appoint, as additional directors of Wesbanco, Jeremy
     C. McCamic and Abigail M. Feinknopf. Jeremy C. McCamic shall serve as a
     member of the Board of Directors until December 31, 2002, at which time he
     shall resign and he shall be replaced by Jay T. McCamic who shall be
     appointed by the Board to serve the unexpired term. Wesbanco shall then
     include the said Abigail M. Feinknopf and Jay T. McCamic on the list of
     nominees for the position of director for which the Board shall solicit
     proxies at its next annual meeting of shareholders until each has served at
     least a full three year term. During his term on the Board, the said Jeremy
     C. McCamic shall also be appointed to the Executive Committee. Wesbanco
     will take such action under its Bylaws as is necessary to permit the said
     Jeremy C. McCamic to serve as a Director until December 31, 2002, with
     respect to its age 70 provision.

     4. Section 8.6 of said Merger Agreement is hereby deleted in its entirety
and the following Section 8.6 is substituted in its place:

          8.6  No Action, Etc.  Except as disclosed in the Disclosure Schedule
     of American dated not more than 30 days from the date hereof and as
     supplemented not more than thirty (30) days from the date of the First

     Disclosure Schedule"),

                                       B-1


     and as supplemented on the Effective Date, there are no suits, actions,
     proceedings, claims or investigations (formal or informal) pending, or to
     the knowledge of American, threatened against or relating to American, its
     Subsidiary, their business or any of their properties or against any of
     their officers or directors (in their capacity as such) in law or in equity
     or before any governmental agency. There are no suits, actions,
     proceedings, claims or investigations against American, its Subsidiary,
     their properties or against any of their officers or directors (in their
     capacity as such) in law or in equity or before any governmental agency
     which, individually or in the aggregate, would, or is reasonably likely to,
     if determined adversely to such party, materially adversely affect the
     financial condition (present or prospective), businesses, properties or
     operations of American or its Subsidiary or the ability of American or its
     Subsidiary to conduct their business as presently conducted or to
     consummate the transactions contemplated hereby, and American does not know
     of any basis for any such action or proceeding. Except as disclosed in the
     American Disclosure Schedule, American and its Subsidiary are not parties
     or subject to any cease and desist order, agreement or similar arrangement
     with a regulatory authority which restricts their operations or requires
     any action, and neither American nor its Subsidiary is transacting business
     in material violation of any applicable law, ordinance, requirement, rule,
     regulation or order.

     supplemented not more than thirty (30) days from the date of the First
     Amendment Agreement (hereinafter collectively called the "Wesbanco
     Disclosure Schedule"), and as supplemented on the Effective Date, there are
     no suits, actions, proceedings, claims or investigations (formal or
     informal) pending, or to the knowledge of Wesbanco pending or threatened,

     its properties or against any of their officers or directors (in their
     capacity as such) in law or in equity or before any governmental agency.
     There are no suits, actions, proceedings, claims or investigations against
     or relating to Wesbanco, its subsidiaries, its businesses, its properties
     or against any of their officers or directors (in their capacity as such)
     in law or in equity or before any governmental agency, which, individually
     or in the aggregate, would, or is reasonably likely to, if determined
     adversely to such party, materially adversely affect the financial
     condition (present or prospective), businesses, properties or operations of
     Wesbanco or its subsidiaries or the ability of Wesbanco or its subsidiaries
     to conduct its business as presently conducted or consummate the
     transaction contemplated hereby, and Wesbanco does not know of any basis

     subsidiaries are a party or subject to any cease and desist order,
     agreement or similar arrangement with a regulatory authority which
     restricts its operations or requires any action and neither Wesbanco nor
     any of its subsidiaries are transacting business in material violation of
     any applicable law, ordinance, requirement, rule, order or regulation.

                                                                         ANNEX C

                             STOCK OPTION AGREEMENT

     THIS STOCK OPTION AGREEMENT ("Option Agreement") dated as of the 22nd day
of February, 2001, by and between WESBANCO, INC., a West Virginia corporation
("Wesbanco") and AMERICAN BANCORPORATION, an Ohio corporation ("American").

                                  WITNESSETH:

     WHEREAS, the Boards of Directors of Wesbanco and American have approved an
Agreement and Plan of Merger ("Merger Agreement"), which contemplates the merger
of American with AB Corporation, a West Virginia corporation and wholly-owned
subsidiary of Wesbanco ("AB"), with AB continuing as the surviving corporation;

     WHEREAS, as a condition to Wesbanco's entry into the Merger Agreement and
to induce such entry, American has agreed to grant to Wesbanco the option set
forth herein to purchase authorized but unissued shares of common stock, without
par value, of American ("American Common Stock");

     NOW, THEREFORE, in consideration of the premises herein contained, the
parties agree as follows:

     1.  Definitions.  Capitalized terms defined in the Merger Agreement and
used herein shall have the same meanings as in the Merger Agreement.

     2.  Grant of Option.  Subject to the terms and conditions set forth herein,
American hereby grants to Wesbanco an option ("Option") to purchase up to
622,805 shares of American Common Stock, at a price of $18.00 per share (the
"Option Price") payable in cash as provided in Section 4 hereof; provided,
however, that in the event American issues or agrees to issue any shares of
American Common Stock (other than as permitted under the Merger Agreement) at a
price less than $18.00 per share (as adjusted pursuant to Section 6 hereof), the
exercise price shall be equal to such lesser price.

     3.  Exercise of Option.

          a. Provided that Wesbanco is not in material breach of the agreements
     and covenants contained in the Merger Agreement, Wesbanco may exercise the
     Option, in whole or in part, at any time or from time to time if a Purchase
     Event (as defined below) shall have occurred and be continuing; provided
     that to the extent the Option shall not have been exercised, it shall
     terminate and be of no further force and effect (i) on the Effective Date
     of the Merger or (ii) upon termination of the Merger Agreement in
     accordance with the provisions thereof (other than a termination resulting
     from a willful breach by American of Section 8.21(d) of the Merger
     Agreement or, following the occurrence of a Purchase Event, failure of
     American's shareholders to approve the Merger Agreement by the vote
     required under applicable law), or (iii) six months after termination of
     the Merger Agreement due to a willful breach by American of Section 8.21(d)
     of the Merger Agreement or, following the occurrence of a Purchase Event,
     failure of American's shareholders to approve the Merger Agreement by the
     vote required under applicable law; and provided further that any such
     exercise shall be subject to compliance with applicable provisions of law.

          b. As used herein, a "Purchase Event" shall mean any of the following
     events or transactions occurring after the date hereof:

             (i) any person (other than American, Wheeling National Bank (the
        "American Subsidiary"), Wesbanco or any affiliate of Wesbanco) shall
        have commenced a bona fide tender or exchange offer to purchase shares
        of American Common Stock such that upon consummation of such offer such
        person would own or control 15% or more of the outstanding shares of
        American Common Stock;

             (ii) any person (other than American or the American Subsidiary),
        other than in connection with a transaction to which Wesbanco has given
        its prior written consent, shall have filed an

                                       C-1


        application or notice with any federal or state regulatory agency for
        clearance or approval, to (x) merge or consolidate, or enter into any
        similar transaction, with American or the American Subsidiary, (y)
        purchase, lease or otherwise acquire all or substantially all of the
        assets of American or the American Subsidiary or (z) purchase or
        otherwise acquire (including by way of merger, consolidation, share
        exchange or any similar transaction) securities representing 51% or more
        of the voting power of American or the American Subsidiary;

             (iii) any person (other than American, the American Subsidiary, the
        American Subsidiary in a fiduciary capacity, Wesbanco, affiliates of
        Wesbanco or subsidiaries of Wesbanco in a fiduciary capacity) shall have
        acquired after the date hereof beneficial ownership or the right to
        acquire beneficial ownership of 15% or more of the outstanding shares of
        American Common Stock (the term "beneficial ownership" for purposes of
        this Option Agreement having the meaning assigned thereto in Section
        13(d) of the Exchange Act and the regulations promulgated thereunder);

             (iv) any person (other than American or the American Subsidiary)
        shall have made a bona fide proposal to American by public announcement
        or written communication that is or becomes the subject of public
        disclosure to (x) acquire American or the American Subsidiary by merger,
        consolidation, purchase of all or substantially all of its assets or any
        other similar transaction, or (y) make an offer described in clause (i)
        above; or

             (v) American shall have willfully breached Section 8.21(d) of the
        Merger Agreement, which breach would entitle Wesbanco to terminate such
        Merger Agreement and such breach shall not have been cured prior to the
        Notice Date (as defined below).

If more than one of the transactions giving rise to a Purchase Event under this
Section 3(b) is undertaken or effected, then all such transactions shall give
rise only to one Purchase Event, which Purchase Event shall be deemed continuing
for all purposes hereunder until all such transactions are abandoned. As used in
this Option Agreement, "person" shall have the meanings specified in Sections
3(a)(9) and 13(d)(3) of the Exchange Act.

          c. In the event Wesbanco wishes to exercise the Option, it shall send
     to American a written notice (the date of which being herein referred to as
     "Notice Date") specifying (i) the total number of shares it will purchase
     pursuant to such exercise, and (ii) a place and date not earlier than three
     business days nor later than 60 business days from the Notice Date for the
     closing of such purchase ("Closing Date"); provided that if prior
     notification to or approval of any federal or state regulatory agency is
     required in connection with such purchase, Wesbanco shall promptly file the
     required notice or application for approval and shall expeditiously process
     the same and the period of time that otherwise would run pursuant to this
     sentence shall run instead from the date on which any required notification
     period has expired or been terminated or such approval has been obtained
     and any requisite waiting period shall have passed.

     4.  Payment and Delivery of Certificates.

          a. At the closing referred to in Section 3(c) hereof, Wesbanco shall
     pay to American the aggregate purchase price for the shares of American
     Common Stock purchased pursuant to the exercise of the Option in
     immediately available funds by a wire transfer to a bank account designated
     by American.

          b. At such closing, simultaneously with the delivery of cash as
     provided in subsection (a), American shall deliver to Wesbanco a
     certificate or certificates representing the number of shares of American
     Common Stock purchased by Wesbanco, and Wesbanco shall deliver to American
     a letter agreeing that Wesbanco will not offer to sell or otherwise dispose
     of such shares in violation of applicable law or the provisions of this
     Option Agreement.

          c. Certificates for American Common Stock delivered at a closing
     hereunder may be endorsed with a restrictive legend which shall read
     substantially as follows:

             "The transfer of the shares represented by this certificate is
        subject to certain provisions of an agreement between the registered
        holder hereof and American Bancorporation and to resale
                                       C-2


        restrictions arising under the Securities Act of 1933, as amended, a
        copy of which agreement is on file at the principal office of American
        Bancorporation. A copy of such agreement will be provided to the holder
        hereof without charge upon receipt by American Bancorporation of a
        written request."

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if Wesbanco shall have
delivered to American a copy of a letter from the staff of the Securities and
Exchange Commission, or an opinion of counsel, in form and substance reasonably
satisfactory to American, to the effect that such legend is not required for
purposes of the Securities Act.

     5.  Representations.  American hereby represents, warrants and covenants to
Wesbanco as follows:

          a. American shall at all times maintain sufficient authorized but
     unissued shares of American Common Stock so that the Option may be
     exercised without authorization of additional shares of American Common
     Stock.

          b. The shares to be issued upon due exercise, in whole or in part, of
     the Option, when paid for as provided herein, will be duly authorized,
     validly issued, fully paid and nonassessable.

     6.  Adjustment Upon Changes in Capitalization.  In the event of any change
in American Common Stock by reason of stock dividends, split-ups, mergers,
recapitalizations, combinations, exchanges of shares or the like, the type and
number of shares subject to the Option, and the purchase price per share, as the
case may be, shall be adjusted appropriately. In the event that any additional
shares of American Common Stock are issued or otherwise become outstanding after
the date of this Option Agreement (other than pursuant to this Option
Agreement), the number of shares of American Common Stock subject to the Option
shall be adjusted so that, after such issuance, it equals 19.9% of the number of
shares of American Common Stock then issued and outstanding without giving
effect to any shares subject or issued pursuant to the Option. Nothing contained
in this Section 6 shall be deemed to authorize American to breach any provision
of the Merger Agreement.

     7.  Registration Rights.  American shall, if requested by Wesbanco, as
expeditiously as possible file a registration statement on a form of general use
under the Securities Act if necessary in order to permit the sale or other
disposition of the shares of American Common Stock that have been acquired upon
exercise of the Option in accordance with the intended method of sale or other
disposition requested by Wesbanco. Wesbanco shall provide all information
reasonably requested by American for inclusion in any registration statement to
be filed hereunder. American will use its best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 270 days from the day such registration
statement first becomes effective as may be reasonably necessary to effect such
sales or other dispositions. In no event shall American be required to effect
more than two registrations hereunder. All expenses of registrations hereunder
shall be borne equally by American and Wesbanco. The filing of any registration
statement hereunder may be delayed for such period of time as may reasonably be
required to facilitate any public distribution by American of American Common
Stock. If requested by Wesbanco, in connection with any such registration,
American will become a party to any underwriting agreement relating to the sale
of such shares, but only to the extent of obligating itself in respect of
representations, warranties, indemnities and other agreements customarily
included in such underwriting agreements. Upon receiving any request from
Wesbanco or assignee thereof under this Section 7, American agrees to send a
copy thereof to Wesbanco and to any assignee thereof known to American, in each
case by promptly mailing the same, postage prepaid, to the address of record of
the persons entitled to receive such copies.

     8.  Severability.  If any term, provision, covenant or restriction
contained in this Option Agreement is held by a court or a federal or state
regulatory agency of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions and covenants and
restrictions contained in this Option Agreement shall remain in full force and
effect, and shall in no way be affected, impaired or invalidated. If for any
reason such court or regulatory agency determines that the Option will not
permit the holder to acquire the full number of shares of American Common Stock
provided in Section 2 hereof (as adjusted pursuant to Section 6 hereof), it is
the express intention of American to allow the holder to acquire such lesser
number of shares as may be permissible, without any amendment or modification
hereof.

                                       C-3


     9.  Put-Back Rights.

          a. Upon the consummation of any Purchase Event described in Section
     3(b)(ii) or (v) hereof such that (i) a merger, consolidation, purchase,
     lease or acquisition of all or substantially all of the assets of American
     purchase or other acquisition of securities representing 51% or more of the
     voting power of American or the American Subsidiary has been consummated,
     or (ii) a willful breach under Section 8.21(d) of the Merger Agreement has
     occurred so that Wesbanco would be entitled to terminate the Merger
     Agreement, and prior to the expiration of the Option in accordance with the
     terms hereof, at the request of Wesbanco, American shall repurchase the
     Option from Wesbanco at a price (the "Repurchase Price") equal to the
     difference between the market/offer price (as defined below) for shares of
     American Common Stock and the Option Price, multiplied by the number of
     shares for which the Option being surrendered hereunder may then be
     exercised but only if the market/offer price is greater than the Option
     Price (the market/offer price is defined as the higher of the price per
     share at which a tender offer or exchange offer for 51% or more of the
     voting securities of American has been made and consummated, the price per
     share actually paid by any third party pursuant to an agreement that has
     been consummated whereby American has been merged, consolidated with or
     otherwise acquired by a third party, and the highest closing price for
     American Common Stock within the four-month period immediately preceding
     the date Wesbanco gives written notice of the required repurchase of the
     Option pursuant to this Section 9). In the event that an exchange offer is
     made or an agreement is entered into for a merger or consolidation
     involving consideration other than cash, the value of the securities or
     other property issuable or deliverable in exchange for American Common
     shall be determined by a nationally recognized investment banking firm
     mutually acceptable to the parties hereto.

          b. Wesbanco may exercise its right to require American to repurchase
     the Option pursuant to this Section 9 by giving American written notice of
     its exercise of its repurchase right in accordance with the provisions of
     this Section 9. Subject to the last proviso of paragraph 9(c) below, as
     promptly as practicable, and in any event within five business days after
     the receipt of such notice or notices relating thereto, American shall
     deliver or cause to be delivered to Wesbanco the Repurchase Price for the
     Option or the portion thereof which American is not then prohibited under
     applicable law and regulation from so delivering.

          c. To the extent that American is prohibited under applicable law or
     regulation, or as a result of administrative or judicial action, from
     repurchasing the Option in full, American shall immediately so notify
     Wesbanco and thereafter deliver or cause to be delivered, from time to
     time, to Wesbanco, as appropriate, the portion of the Repurchase Price
     which it is no longer prohibited from delivering, within five business days
     after the date on which American is no longer so prohibited, provided,
     however, that to the extent that American is at the time and after the
     expiration of 12 months, so prohibited from delivering to Wesbanco, the
     Repurchase Price, in full (and American hereby undertakes to use its best
     efforts to receive all required regulatory and legal approvals as promptly
     as practicable), American shall deliver to Wesbanco a new Option evidencing
     the right of Wesbanco to purchase that number of shares of American Common
     Stock obtained by multiplying the number of shares of American Common Stock
     for which the Option may at such time be exercised by a fraction, the
     numerator of which is the Repurchase Price less the portion thereof (if
     any) theretofore delivered to the Holder and the denominator of which is
     the Repurchase Price, and American shall have no further obligation to
     repurchase such new Option; and provided, further, that upon receipt of
     such notice and until five days thereafter Wesbanco may revoke its notice
     of repurchase of the Option by written notice to American at its principal
     office stating that Wesbanco elects to revoke its election to exercise its
     rights to require American to repurchase the Option, whereupon American
     will promptly deliver to Wesbanco the Option and American shall have no
     further obligation to repurchase such Option.

     10.  First Refusal.  If at any time during the eighteen months immediately
following the first purchase of shares of American Common Stock pursuant to the
Option, Wesbanco shall desire to sell, assign, transfer or otherwise dispose of
all or any of the shares of American Common Stock acquired by it pursuant to the
Option other than in accordance with the put-back rights in Section 9 hereof, it
shall give American written notice of the proposed transaction ("Offeror's
Notice"), identifying the proposed transferee and setting forth the terms
                                       C-4


of the proposed transaction. An Offeror's Notice shall be deemed an offer by
Wesbanco to American, which may be accepted within ten business days of the
receipt of such Offeror's Notice, on the same terms and conditions and at the
same price at which Wesbanco is proposing to transfer such shares to a third
party. Settlement for any shares purchased by American shall be within 15
business days of the date of the acceptance of the offer and the purchase price
shall be paid to Wesbanco in immediately available funds; provided that if prior
notification to or approval of any federal or state regulatory authority is
required in connection with such purchase, American shall promptly file the
required notice or application for approval and shall expeditiously process the
same and the period of time that otherwise would run pursuant to this sentence
shall run instead from the date on which any required notification period has
expired or been terminated or such approval has been obtained and any requisite
waiting period shall have passed. In the event of the failure or refusal of
American to purchase all of the shares covered by the Offeror's Notice or any
applicable regulatory authority shall disapprove American's proposed purchase of
such shares, Wesbanco may sell all, but not less than all, of such shares to
such third party at no less than the price specified and on terms no more
favorable than those set forth in the Offeror's Notice. The requirements of this
Section 9 shall not apply to any disposition (i) as a result of which the
proposed transferee would own not more than five percent of the then outstanding
shares of American Common Stock, (ii) of American Common Stock by a person to
which Wesbanco has assigned its rights under the Option in accordance with
Section 11(c) hereof or (iii) pursuant to a registration under Section 7 hereof.

     11.  Miscellaneous.

          a. Expenses.  Except as otherwise provided herein, each of the parties
     hereto shall bear and pay all costs and expenses incurred by it or on its
     behalf in connection with the transactions contemplated hereunder,

     except as expressly provided herein.

          c. Assignment.  Neither of the parties hereto may assign any of its

     the Merger Agreement.

          e. Counterparts.  This Option Agreement may be executed in any number
     of counterparts, and each such counterpart shall be deemed to be an
     original instrument, but all such counterparts together shall constitute
     but one agreement.

          f. Specific Performance.  The parties agree that damages would be an
     inadequate remedy for a breach of the provisions of this Option Agreement
     by either party hereto and that this Option Agreement may be enforced by

Agreement as of the day and year first written above.

Board of Directors
American Bancorporation
Suite 800, Hawley Building
1025 Main Street
Wheeling, WV 26003

Attention:  Jeremy C. McCamic
          Chairman & CEO

Members of the Board:

     You have requested our opinion with respect to the fairness, from a
financial point of view, as of the date hereof, to the holders of the common
stock, without par value ("American Common Stock"), of American Bancorporation
("American"), of the Exchange Ratio, as set forth in Section 6.1 (a) of the
Agreement and Plan of Merger dated as of February 22, 2001 as amended (the
"Agreement"), by and among American, AB Corporation, a corporation to be formed
as a wholly-owned subsidiary of WesBanco, Inc., WesBanco, Inc. ("WesBanco"), and
WesBanco Bank, Inc.

     The Agreement provides for the merger (the "Merger") of American with and
into AB Corporation, pursuant to which, among other things, at the Effective
Time (as defined in the Agreement), each outstanding share of American Common
Stock will be exchanged for the right to receive 1.1 shares (the "Exchange
Ratio") of the common stock, par value $2.0833 per share, of WesBanco ("WesBanco
Common Stock"), as set forth in Section 6.1 (a) of the Agreement. The terms and
conditions of the Merger are more fully set forth in the Agreement.

     McDonald Investments Inc., as part of its investment banking business, is
customarily engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes.

     We have acted as American's financial advisor in connection with, and have
participated in certain negotiations leading to, the Agreement. In connection
with rendering our opinion set forth herein, we have among other things:

          (i) Reviewed American's Annual Reports to Shareholders and Annual
     Reports on Form 10-K for each of the years ended December 31, 2000,
     December 31, 1999 and December 31, 1998, including the audited financial
     statements contained therein, and American's Quarterly Reports on Form 10-Q
     for each of the quarters ended September 30, 2001, June 30, 2001, and March
     31, 2001;

          (ii) Reviewed WesBanco's Annual Reports to Shareholders and Annual
     Reports on Form 10-K for each of the years ended December 31, 2000,
     December 31, 1999 and December 31, 1998, including the audited financial
     statements contained therein, and WesBanco's Quarterly Reports on Form 10-Q
     for each of the quarters ended September 30, 2001, June 30, 2001, and March
     31, 2001;

          (iii) Reviewed certain other public and non-public information,
     primarily financial in nature, relating to the respective businesses,
     earnings, assets and prospects of American and WesBanco provided to us or
     publicly available;

                                       D-1


          (iv) Participated in meetings and telephone conferences with members
     of senior management of American and WesBanco concerning the financial
     condition, business, assets, financial forecasts and prospects of the
     respective companies, as well as other matters we believed to be relevant
     to our inquiry;

          (v) Reviewed certain stock market information for American Common
     Stock and WesBanco Common Stock, and compared it with similar information
     for certain companies, the securities of which are publicly traded;

          (vi) Compared the results of operations and financial condition of
     American and WesBanco with that of certain companies, which we deemed to be
     relevant for purposes of this opinion;

          (vii) Reviewed the financial terms, to the extent publicly available,
     of certain acquisition transactions, which we deemed to be relevant for
     purposes of this opinion;

          (viii) Reviewed the Agreement dated February 22, 2001 as amended and
     certain related documents;

          (ix) Reviewed the proxy statement/prospectus for the Merger; and

          (x) Performed such other reviews and analyses as we have deemed
     appropriate.

     In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information reviewed by us and have relied upon the accuracy and completeness of
the representations, warranties and covenants of American and WesBanco contained
in the Agreement. We have not been engaged to undertake, and have not assumed
any responsibility for, nor have we conducted, an independent investigation or
verification of such matters. We have not been engaged to and we have not
conducted a physical inspection of any of the assets, properties or facilities
of either American or WesBanco, nor have we made or obtained or been furnished
with any independent valuation or appraisal of any of such assets, properties or
facilities or any of the liabilities of either American or WesBanco. With
respect to financial forecasts used in our analysis, we have assumed that such
forecasts have been reasonably prepared by management of American and WesBanco,
as the case may be, on a basis reflecting the best currently available estimates
and judgments of the management of American and WesBanco, as to the future
performance of American, WesBanco, and American and WesBanco combined, as the
case may be. We have not been engaged to and we have not assumed any
responsibility for, nor have we conducted any independent investigation or
verification of such matters, and we express no view as to such financial
forecasts or the assumptions on which they are based. We have also assumed that
all of the conditions to the consummation of the Merger, as set forth in the
Agreement, including the tax-free treatment of the Merger to the holders of
American Common Stock, would be satisfied and that the Merger would be
consummated on a timely basis in the manner contemplated by the Agreement.

     We will receive a fee for our services as financial advisor to American, a
substantial portion of which is contingent upon closing of the Merger. We will
also receive a fee for our services in rendering this opinion.

     In the ordinary course of business, we may actively trade securities of
American and WesBanco for our own account and for the accounts of customers and
accordingly, we may at any time hold a long or short position in such
securities.

     This opinion is based on economic and market conditions and other
circumstances existing on, and information made available as of, the date
hereof. In addition, our opinion is, in any event, limited to the fairness, as
of the date hereof, from a financial point of view, of the Exchange Ratio, to
the holders of American Common Stock, and does not address the underlying
business decision by American's Board of Directors to effect the Merger, does
not compare or discuss the relative merits of any competing proposal or any
other terms of the Merger, and does not constitute a recommendation to any
American shareholder as to how such shareholder should vote with respect to the
Merger. This opinion does not represent an opinion as to what the value of
American Common Stock or WesBanco Common Stock may be at the Effective Time of
the Merger or as to the prospects of American's business or WesBanco's business.

                                       D-2


     This opinion is directed to the Board of Directors of American and may not
be reproduced, summarized, described or referred to or given to any other person
without our prior written consent. Notwithstanding the foregoing, this opinion
may be included in the proxy statement to be mailed to the holders of American
Common Stock in connection with the Merger, provided that this opinion will be
reproduced in such proxy statement in full, and any description of or reference
to us or our actions, or any summary of the opinion in such proxy statement,
will be in a form reasonably acceptable to us and our counsel.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Exchange Ratio is fair to the holders of American Common Stock
from a financial point of view.

                                          Very truly yours,


                                          /s/  McDONALD INVESTMENTS INC.


                                          McDONALD INVESTMENTS INC.

                                       D-3


                                                                         ANNEX E

Section 1701.84  PERSONS ENTITLED TO RELIEF AS DISSENTING SHAREHOLDERS.

     The following are entitled to relief as dissenting shareholders under
section 1701.85 of the Revised Code:

     (A) Shareholders of a domestic corporation that is being merged or
consolidated into a surviving or new entity, domestic or foreign, pursuant to
section 1701.78, 1701.781, 1701.79, 1701.791, or 1701.801 of the Revised Code;

     (B) In the case of a merger into a domestic corporation, shareholders of
the surviving corporation who under section 1701.78 or 1701.781 of the Revised
Code are entitled to vote on the adoption of an agreement of merger, but only as
to the shares so entitling them to vote;

     (C) Shareholders, other than the parent corporation, of a domestic
subsidiary corporation that is being merged into the domestic or foreign parent
corporation pursuant to section 1701.80 of the Revised Code;

     (D) In the case of a combination or a majority share acquisition,
shareholders of the acquiring corporation who under section 1701.83 of the
Revised Code are entitled to vote on such transaction, but only as to the shares
so entitling them to vote;

     (E) Shareholders of a domestic subsidiary corporation into which one or
more domestic or foreign corporations are being merged pursuant to section
1701.801 of the Revised Code.

Effective date: 10-4-1996

Section 1701.85  DISSENTING SHAREHOLDER'S DEMAND FOR FAIR CASH VALUE OF SHARES.

     (A)(1) A shareholder of a domestic corporation is entitled to relief as a
dissenting shareholder in respect of the proposals described in sections
1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with this
section.

     (2) If the proposal must be submitted to the shareholders of the
corporation involved, the dissenting shareholder shall be a record holder of the
shares of the corporation as to which he seeks relief as of the date fixed for
the determination of shareholders entitled to notice of a meeting of the
shareholders at which the proposal is to be submitted, and such shares shall not
have been voted in favor of the proposal. Not later than ten days after the date
on which the vote on the proposal was taken at the meeting of the shareholders,
the dissenting shareholder shall deliver to the corporation a written demand for
payment to him of the fair cash value of the shares as to which he seeks relief,
which demand shall state his address, the number and class of such shares, and
the amount claimed by him as the fair cash value of the shares.

     (3) The dissenting shareholder entitled to relief under division (C) of
section 1701.84 of the Revised Code in the case of a merger pursuant to section
1701.80 of the Revised Code and a dissenting shareholder entitled to relief
under division (E) of section 1701.84 of the Revised Code in the case of a
merger pursuant to section 1701.801 of the Revised Code shall be a record holder
of the shares of the corporation as to which he seeks relief as of the date on
which the agreement of merger was adopted by the directors of that corporation.
Within twenty days after he has been sent the notice provided in section 1701.80
or 1701.801 of the Revised Code, the dissenting shareholder shall deliver to the
corporation a written demand for payment with the same information as that
provided for in division (A)(2) of this section.

     (4) In the case of a merger or consolidation, a demand served on the
constituent corporation involved constitutes service on the surviving or the new
entity, whether the demand is served before, on, or after the effective date of
the merger or consolidation.

     (5) If the corporation sends to the dissenting shareholder, at the address
specified in his demand, a request for the certificates representing the shares
as to which he seeks relief, the dissenting shareholder, within fifteen days
from the date of the sending of such request, shall deliver to the corporation
the certificates requested so that the corporation may forthwith endorse on them
a legend to the effect that demand for the

                                       E-1


fair cash value of such shares has been made. The corporation promptly shall
return such endorsed certificates to the dissenting shareholder. A dissenting
shareholder's failure to deliver such certificates terminates his rights as a
dissenting shareholder, at the option of the corporation, exercised by written
notice sent to the dissenting shareholder within twenty days after the lapse of
the fifteen-day period, unless a court for good cause shown otherwise directs.
If shares represented by a certificate on which such a legend has been endorsed
are transferred, each new certificate issued for them shall bear a similar
legend, together with the name of the original dissenting holder of such shares.
Upon receiving a demand for payment from a dissenting shareholder who is the
record holder of uncertificated securities, the corporation shall make an
appropriate notation of the demand for payment in its shareholder records. If
uncertificated shares for which payment has been demanded are to be transferred,
any new certificate issued for the shares shall bear the legend required for
certificated securities as provided in this paragraph. A transferee of the
shares so endorsed, or of uncertificated securities where such notation has been
made, acquires only such rights in the corporation as the original dissenting
holder of such shares had immediately after the service of a demand for payment
of the fair cash value of the shares. A request under this paragraph by the
corporation is not an admission by the corporation that the shareholder is
entitled to relief under this section.

     (B) Unless the corporation and the dissenting shareholder have come to an
agreement on the fair cash value per share of the shares as to which the
dissenting shareholder seeks relief, the dissenting shareholder or the
corporation, which in case of a merger or consolidation may be the surviving or
new entity, within three months after the service of the demand by the
dissenting shareholder, may file a complaint in the court of common pleas of the
county in which the principal office of the corporation that issued the shares
is located or was located when the proposal was adopted by the shareholders of
the corporation, or, if the proposal was not required to be submitted to the
shareholders, was approved by the directors. Other dissenting shareholders,
within that three-month period, may join as plaintiffs or may be joined as
defendants in any such proceeding, and any two or more such proceedings may be
consolidated. The complaint shall contain a brief statement of the facts,
including the vote and the facts entitling the dissenting shareholder to the
relief demanded. No answer to such a complaint is required. Upon the filing of
such a complaint, the court, on motion of the petitioner, shall enter an order
fixing a date for a hearing on the complaint and requiring that a copy of the
complaint and a notice of the filing and of the date for hearing be given to the
respondent or defendant in the manner in which summons is required to be served
or substituted service is required to be made in other cases. On the day fixed
for the hearing on the complaint or any adjournment of it, the court shall
determine from the complaint and from such evidence as is submitted by either
party whether the dissenting shareholder is entitled to be paid the fair cash
value of any shares and, if so, the number and class of such shares. If the
court finds that the dissenting shareholder is so entitled, the court may
appoint one or more persons as appraisers to receive evidence and to recommend a
decision on the amount of the fair cash value. The appraisers have such power
and authority as is specified in the order of their appointment. The court
thereupon shall make a finding as to the fair cash value of a share and shall
render judgment against the corporation for the payment of it, with interest at
such rate and from such date as the court considers equitable. The costs of the
proceeding, including reasonable compensation to the appraisers to be fixed by
the court, shall be assessed or apportioned as the court considers equitable.
The proceeding is a special proceeding and final orders in it may be vacated,
modified, or reversed on appeal pursuant to the Rules of Appellate Procedure
and, to the extent not in conflict with those rules, Chapter 2505. of the
Revised Code. If, during the pendency of any proceeding instituted under this
section, a suit or proceeding is or has been instituted to enjoin or otherwise
to prevent the carrying out of the action as to which the shareholder has
dissented, the proceeding instituted under this section shall be stayed until
the final determination of the other suit or proceeding. Unless any provision in
division (D) of this section is applicable, the fair cash value of the shares
that is agreed upon by the parties or fixed under this section shall be paid
within thirty days after the date of final determination of such value under
this division, the effective date of the amendment to the articles, or the
consummation of the other action involved, whichever occurs last. Upon the
occurrence of the last such event, payment shall be made immediately to a holder
of uncertificated securities entitled to such payment. In the case of holders of
shares represented by certificates, payment shall be made only upon and
simultaneously with the surrender to the corporation of the certificates
representing the shares for which the payment is made.

                                       E-2


     (C) If the proposal was required to be submitted to the shareholders of the
corporation, fair cash value as to those shareholders shall be determined as of
the day prior to the day on which the vote by the shareholders was taken and, in
the case of a merger pursuant to section 1701.80 or 1701.801 of the Revised
Code, fair cash value as to shareholders of a constituent subsidiary corporation
shall be determined as of the day before the adoption of the agreement of merger
by the directors of the particular subsidiary corporation. The fair cash value
of a share for the purposes of this section is the amount that a willing seller
who is under no compulsion to sell would be willing to accept and that a willing
buyer who is under no compulsion to purchase would be willing to pay, but in no
event shall the fair cash value of a share exceed the amount specified in the
demand of the particular shareholder. In computing such fair cash value, any
appreciation or depreciation in market value resulting from the proposal
submitted to the directors or to the shareholders shall be excluded.

     (D)(1) The right and obligation of a dissenting shareholder to receive such
fair cash value and to sell such shares as to which he seeks relief, and the
right and obligation of the corporation to purchase such shares and to pay the
fair cash value of them terminates if any of the following applies:

          (a) The dissenting shareholder has not complied with this section,
     unless the corporation by its directors waives such failure;

          (b) The corporation abandons the action involved or is finally
     enjoined or prevented from carrying it out, or the shareholders rescind
     their adoption of the action involved;

          (c) The dissenting shareholder withdraws his demand, with the consent
     of the corporation by its directors;

          (d) The corporation and the dissenting shareholder have not come to an
     agreement as to the fair cash value per share, and neither the shareholder
     nor the corporation has filed or joined in a complaint under division (B)
     of this section within the period provided in that division.

     (2) For purposes of division (D)(1) of this section, if the merger or
consolidation has become effective and the surviving or new entity is not a
corporation, action required to be taken by the directors of the corporation
shall be taken by the general partners of a surviving or new partnership or the
comparable representatives of any other surviving or new entity.

     (E) From the time of the dissenting shareholder's giving of the demand
until either the termination of the rights and obligations arising from it or
the purchase of the shares by the corporation, all other rights accruing from
such shares, including voting and dividend or distribution rights, are
suspended. If during the suspension, any dividend or distribution is paid in
money upon shares of such class or any dividend, distribution, or interest is
paid in money upon any securities issued in extinguishment of or in substitution
for such shares, an amount equal to the dividend, distribution, or interest
which, except for the suspension, would have been payable upon such shares or
securities, shall be paid to the holder of record as a credit upon the fair cash
value of the shares. If the right to receive fair cash value is terminated other
than by the purchase of the shares by the corporation, all rights of the holder
shall be restored and all distributions which, except for the suspension, would
have been made shall be made to the holder of record of the shares at the time
of termination.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Wesbanco's Bylaws provide, and West Virginia law permits (W. Va. Code sec.
31-1-9), the indemnification of directors and officers against certain
liabilities. Officers and directors of Wesbanco and its subsidiaries are
indemnified generally against expenses reasonably incurred in connection with
proceedings in which they are made parties by reason of their being or having
been directors or offices of the corporation, except in relation to matters as
to which a recovery may be obtained by reason of an officer or director having
been finally adjudged derelict in such action or proceeding in the performance
of his duties.

     A. Excerpts from Article VI of the Bylaws of Wesbanco:

INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Each director and officer, whether or not then in office, shall be
indemnified by the corporation against all costs and expenses reasonably
incurred by and imposed upon him in connection with or resulting from any
action, suit or proceeding, to which he may be made a party by reason of his
being or having been a director or officer of the corporation, or of any other
company which he served at the request of the corporation, except in relation to
matters as to which a recovery shall be had against him by reason of his having
been finally adjudged derelict in such action, suit or proceeding, in the
performance of his duties as such director or officer, and the foregoing right
of indemnification shall not be exclusive of other rights to which he may be
entitled as a matter of law.

     B. West Virginia Corporation Law, W. Va. Code sec. 31-1-9:

SECTION 31-1-9.  INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS.

     (a) A corporation shall have power to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines, taxes and penalties and interest thereon, and amounts
paid in settlement actually and reasonably incurred by him in connection with
such action or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action or proceeding by judgment, order, settlement, conviction, or upon a plea
of nolo contendere or its equivalent, shall not, of itself, create a presumption
that the person did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interest of the corporation, and,
with respect to any criminal action or proceeding, that such person did have
reasonable cause to believe that his conduct was unlawful.

     (b) A corporation shall have power to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or proceeding by or in the right of the corporation to procure
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or proceeding if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, except that no indemnification
shall be made in respect of any claim, issue or matter, including, but not
limited to, taxes or any interest or penalties thereon, as to which such person
shall have been adjudged to be liable for negligence or misconduct in the
performance of his duty to the corporation unless and only to the extent that
the court in which such action or proceeding was brought shall

                                       II-1


determine upon application that, despite the adjudication of liability but in
view of all circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which such court shall deem proper.

     (c) To the extent that a director, officer, employee or agent of a
corporation has been successful on the merits or otherwise in defense of any
action or proceeding referred to in subsection (a) or (b), or in defense of any
claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

     (d) Any indemnification under subsection (a) or (b) (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in subsection (a) or (b). Such determination shall be made
(1) by the board of directors by a majority vote of a quorum consisting of
directors who were not parties to such action or proceeding, or (2) if such a
quorum is not obtainable, or even if obtainable a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or (3)
by the shareholders or members.

     (e) Expenses (including attorney's fees) incurred in defending a civil or
criminal action or proceeding may be paid by the corporation in advance of the
final disposition of such action or proceeding as authorized in the manner
provided in Subsection (d) upon receipt of an undertaking by or on behalf of the
director, officer, employee or agent to repay such amount unless it shall
ultimately be determined that he is entitled to be indemnified by the
corporation as authorized in this section.

     (f) The indemnification provided by this section shall not be deemed
exclusive of any other rights to which any shareholder or member may be entitled
under any bylaw, agreement, vote of shareholders, members or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, and shall continue as to a
person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of the heirs, executors, and administrators of such a
person.

     (g) A corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee, or agent of another corporation, partnership, joint
partnership, joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity or arising out of
his status as such, whether or not the corporation would have the power to
indemnify him against such liability under the provisions of this section.
(1961,c.15; 1974,c.13; 1975,c.118.)

     Wesbanco does provide indemnity insurance to its officers and directors.
Such insurance will not, however, indemnify officers or directors for willful
misconduct or gross negligence in the performance of a duty to Wesbanco.

ITEM 22.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes as follows:

     (a) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

     (b) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (a) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act of 1933, as amended,
and is used in connection with an offering of securities subject to

                                       II-3


Rule 415, will be filed as a part of an amendment to the registration statement
and will not be used until such amendment is effective, and that, for purposes
of determining any liability under the Securities Act of 1933, as amended, each
such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933, as amended, and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933, as amended, and will be governed by the final
adjudication of such issue.

     (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     (f) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                                       II-4


                                   SIGNATURES
