         Through  Wheeling  National  Bank,  American  provides  a full range of
commercial  banking  services  to retail  customers  and  small to  medium-sized
business in its market area. In eastern Ohio and northern West Virginia American
focuses on local customer needs. In the Columbus,  Ohio area,  American  focuses
its  marketing  efforts on local  businesses,  whose needs are not being  served
effectively  by larger  institutions.  In  southwestern  Pennsylvania,  American
operates an office catering primarily to small business customers.

         The banking services  American offers its customers  include  checking,
savings, time and money market accounts, personal, commercial,  construction and
real estate loans,  individual  retirement  accounts,  safe deposit boxes,  wire
transfers and debit cards, among other standard banking products and services.

         American   operates  two  subsidiaries  that  provide  data  processing
services and  transfer  agent  services  for American and the Wheeling  National
Bank.

THE SPECIAL MEETING

         The Special  Meeting will be held on __________,  February ___, 2002 at
___ p.m., local time, at the offices of American at 1025 Main Street, Suite 800,
Wheeling, West Virginia 26003. The purpose of the Special Meeting is to consider
and vote upon the merger.

         You may  vote  at the  Special  Meeting  only if you  owned  shares  of
American  common stock at the close of business on [record  date].  You may cast
one vote for each share of American  common stock owned by you on that date. The
holders of at least a majority of the shares of American common stock present in
person or by proxy at the  Special  Meeting  must vote in favor of the merger in
order to approve the merger. As of [record date], there were 3,129,674 shares of
American  common stock  outstanding,  held by  approximately  [1,741] 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.

THE MERGER

         We propose a merger of American  with AB  Corporation,  a subsidiary of
Wesbanco that has been formed solely for the purpose of effecting the merger. If
the  merger is  consummated,  AB  Corporation  will  continue  as the  surviving
corporation.  The Articles of  Incorporation  and By-laws of AB Corporation will
continue  as  the  Articles  of  Incorporation  and  By-laws  of  the  surviving
corporation.  The officers and directors of AB Corporation  will continue as the
officers  and  directors of the  Surviving  Corporation.  Following  the merger,
Wheeling National Bank will be merged into Wesbanco Bank and AB Corporation will
be merged into Wesbanco. If the merger is completed, you will receive 1.1 shares
of Wesbanco  common stock for each share of American  common stock that you own.
Instead  of  fractional  shares of  Wesbanco,  you will  receive a check for any
fractional  shares based on a value of $22.31 per whole share of Wesbanco common
stock.

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 _____.

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.



                                       4



         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.

INTERESTS OF AMERICAN DIRECTORS AND OFFICERS IN THE MERGER

         If the Merger is consummated, Jeremy C. McCamic, the Chairman and Chief
Executive Officer of American, and Abigail M. Feinknopf, a director of American,
will be added to the Wesbanco Board of Directors.  Mr. McCamic will serve on the
Wesbanco Board of Directors until December 31, 2002, at which time he has agreed
to resign. Prior to his resignation,  Mr. McCamic will be a member of Wesbanco's
Executive  Committee.  Jay T. McCamic, a director of American,  will be added to
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 three 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,  consulting  agreements or severance plan  clarification  agreements
with Wesbanco and American.  These  agreements  are described  under the heading
"The  Merger - Interest  of Certain  Persons in the  Merger"  beginning  on page
_____.

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:

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

         o the approval by the Board of Governors of the Federal  Reserve System
           of (i) the application of Wesbanco to acquire   American, (ii)    the
           merger of  American  into AB  Corporation  and   (iii) the  merger of
           Wheeling National Bank into Wesbanco Bank;

         o 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

         o 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 IRC,  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 thirty (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/Prospectus,  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  and  regulatory  approvals  have  been
received and all applicable  regulatory waiting periods have expired.  We expect
this to occur during the first quarter of 2002.


                                       5

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.  American  granted  Wesbanco this option to induce Wesbanco to enter into

complete the merger.

         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,  which would permit Wesbanco to exercise this option. See "The

          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 acquisition described below.

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 Pro Forma  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 as if such  transaction  had been
effective during the entire period shown.

The  Unaudited Pro Forma  Condensed  Financial  Information  reflects the merger
based upon preliminary  purchase  accounting  adjustments.  Actual  adjustments,
which may include  adjustments to certain  assets,  liabilities  and other items
including identifiable intangibles,  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.

The  Unaudited  Pro  Forma  Condensed  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.

Estimates of non-recurring  acquisition  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  acquisition  to  approximate  25% to 30% of American's  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 acquisition.

In conjunction with the acquisition,  Wesbanco will be required to divest of 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, not included in the pro forma financial information.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

The  Unaudited  Pro  Forma  Condensed  Financial  Information  is  based  on the
following  adjustments  and  related  assumptions.  The  actual  purchase  price
accounting  adjustments  will be  made on the  basis  of fair  values  as of the
effective date of the merger and, therefore,  may differ from those reflected in
the Unaudited Pro Forma Condensed Financial Information.

NOTE A

The purchase accounting adjustments to record the merger of American used in the
preparation  of the  Unaudited  Pro Forma  Condensed  Combined  Balance Sheet at
September 30, 2001 are summarized as follows:

    American common stock outstanding at September 30, 2001        3,129,674

                                                             -------------------

    Shares issued at market value (average closing price
    for a period preceding and following the date of the
    Merger Agreement)                                               $ 70,540
    Historical net assets acquired                                   (46,733)
                                                             -------------------

    Excess of purchase price over net assets acquired               $ 23,807

the fair  value  of the net  assets  acquired  is  allocated  to  goodwill.  The
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.  Since 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 and after  evaluation of the values are  complete,  the final amounts
may differ  from the  estimates  provided  herein.  Goodwill is  amortized  on a
straight-line basis over a period of 15 years. Fair value adjustments related to
loans, deposits and other borrowings are amortized on a straight-line basis over
the estimated  remaining  portfolio life. Fair value adjustments related to bank
premises are amortized on a straight-line  basis over the estimated  useful life
of the fixed  asset.  Tax  expense  related  to net fair  value  adjustments  is
calculated at a 40% tax rate.

Wesbanco is  currently  evaluating  the  allocation  of goodwill to core deposit
intangibles  and,  therefore,  has not  estimated  its  impact  on the pro forma
financial information.  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.  The  remaining  goodwill  intangible  is not subject to
amortization under the new standards,  however,  will be periodically  evaluated
for  possible  impairment.  SFAS No.  141 and No. 142 are  described  in greater
detail below.

In July 2001,  the  Financial  Accounting  Standards  Board issued SFAS No. 141,
"Business  Combinations"  and SFAS  No.  142,  "Goodwill  and  Other  Intangible
Assets".  SFAS No. 141 requires the purchase  method  accounting be used for all
business combinations  initiated or completed after June 30, 2001 and eliminates
the  pooling-of-interests  method of  accounting.  The statement  also addresses
disclosure  requirements for business  combinations and initial  recognition and
measurement  criteria for goodwill  and other  intangible  assets as a result of
purchase business combinations.

SFAS No. 142 changes the accounting for goodwill from an amortization  method to
an evaluation of possible  impairment  approach.  The  amortization of goodwill,
including goodwill recognized relating to past business


                                       13



combinations,  will cease upon adoption of the new standard.  Impairment testing
for  goodwill at a  reporting  unit level will be required on at least an annual
basis.  The new standard also addresses  other  accounting  matters,  disclosure
requirements and financial  statement  presentation  issues relating to goodwill
and other intangible assets.  Wesbanco will adopt SFAS No. 142 effective January
1, 2002, as required.

NOTE C

The goodwill  allocation in the Unaudited Pro Forma Condensed Balance Sheet also
includes 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.

         On February 21, 2001,  the last full trading day prior to the execution
of the Merger  Agreement,  the closing  price per share of Wesbanco and American
common  stock as  reported on the  National  Market  System of the Nasdaq  Stock
Market was $21.50 and $14.875,  respectively.  On January _____,  2002, the most
recent    practicable    date   prior   to   the    printing   of   this   Proxy
Statement/Prospectus,  the  closing  price per share of  Wesbanco  and  American
common  stock as  reported on the  National  Market  System of the Nasdaq  Stock
Market was $[_____] and [_____], respectively.

         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 in the Merger  Agreement  not to  declare  any  dividends  other than its
normal quarterly  dividend of $0.15 per share. 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.

                           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 ___,  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:

            o   expected cost savings from the merger may not be fully  realized
                or realized within the expected time frame;
            o   the loss of deposits, customers or revenues following the merger
                may be greater than expected;
            o   competitive  pressures  among  depository  and  other  financial
                institutions may increase significantly; o costs or difficulties
                related to the  integration  of the  businesses  of Wesbanco and
                American may be greater than expected;
            o   changes in the interest rate  environment  may reduce margins or
                the volumes or values of loans made or held;
            o   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;
            o   legislative  or  regulatory   changes,   including   changes  in
                accounting standards, may adversely affect the business in which
                Wesbanco and American are engaged; and
            o   competitors  of Wesbanco and American may develop  products that
                enable  those  competitors  to compete  more  successfully  than
                Wesbanco or American.

         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.

                                  RISK FACTORS

WESBANCO'S  STATUS AS A HOLDING COMPANY MAKES IT DEPENDENT ON DIVIDENDS FROM ITS
SUBSIDIARIES TO MEET ITS OBLIGATIONS.

         Wesbanco is a holding company and conducts almost all of its operations
through its  subsidiaries.  Wesbanco does not have any significant  assets other
than the stock of its  subsidiaries.  Accordingly,  Wesbanco depends on the cash
flows  of  its  subsidiaries  to  meet  its  obligations.  Wesbanco's  right  to
participate in any  distribution  of earnings or assets of its  subsidiaries  is
subject to the prior claims of creditors of such subsidiaries. Under federal and
state law,  Wesbanco's bank  subsidiaries are limited in the amount of dividends
they  can  pay  to  Wesbanco  without  prior  regulatory  approval.  Also,  bank
regulators have the authority to prohibit Wesbanco's subsidiary bank from paying
dividends  if they  think the  payment  would be an unsafe and  unsound  banking
practice.

INTEREST RATE VOLATILITY COULD SIGNIFICANTLY HARM WESBANCO'S BUSINESS.

         Wesbanco's  results  of  operations  are  materially  affected  by  the
monetary  and fiscal  policies  of the  federal  government  and the  regulatory
policies of governmental authorities. Wesbanco's profitability will be dependent
to a large extent on its net interest  income,  which is the difference  between
income  on   interest-earning   assets,   such  as   loans,   and   expense   on
interest-bearing  liabilities,  such as  deposits.  A change in market  interest
rates will adversely affect Wesbanco's  earnings if market interest rates change
such that the interest Wesbanco pays on deposits and borrowings increases faster
than the interest it collects on loans and investments.  Consequently, Wesbanco,
along with other financial institutions generally, is sensitive to interest rate
fluctuations.

WESBANCO  MAY  ENCOUNTER  INTEGRATION  DIFFICULTIES  OR MAY FAIL TO REALIZE  THE
ANTICIPATED BENEFITS OF THE MERGER.

         Wesbanco  may not be able  to  integrate  the  operations  of  American
without encountering  difficulties,  including,  without limitation, the loss of
key employees and customers,  the  disruption of ongoing  businesses or possible
inconsistencies in standards,  controls, procedures and policies. While Wesbanco
has successfully integrated past acquisitions, the proposed merger with American
would be by far the  largest  acquisition  undertaken  by  Wesbanco  and will be
significantly  more  difficult  to  integrate  smoothly  and  successfully.   In
addition,  in  determining  that  the  merger  is in the best  interests  of its
shareholders,  Wesbanco's Board of Directors  considered the effects of expected
cost savings, improved efficiencies and cross-marketing opportunities. There can
be no assurance that these expected benefits of the merger will be realized.

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 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/Prospectus
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 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


                                       24



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.

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/prospectus.  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/PROSPECTUS,  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.


                                       25


         McDonald, in connection with rendering its original opinion:

         o  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;

         o  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;

         o  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;

         o  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;

         o  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;

         o  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;

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

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

         o  reviewed the proxy statement for the merger; and

         o  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/Prospectus) 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


                                       26



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  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:

        o   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;

        o   Less than one  percent  (1%)  accretion  to  earnings  for  Wesbanco
            shareholders  in  the  first  year  of  combined  operations;  o  An
            estimated  sixty-seven  percent (67%) accretion in cash dividends in
            the  first  year  for  American   shareholders,   assuming  Wesbanco
            maintained its current dividend policy;

        o   No change in cash dividends for Wesbanco shareholders;

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

        o   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
contributions are listed below by category:

         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");
        * 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

         The following  table  represents a summary  analysis of the  comparable
transactions analyzed by McDonald based on the announced transaction values.

(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.

         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/PROSPECTUS,  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.

         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:

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


                                       32




            o   the  impact  of the  merger  on the  depositors,  customers  and
                communities served by American;
            o   the opinion of McDonald Investments Inc.;
            o   the general  structure of the transaction and the  compatibility
                of management and business philosophy;
            o   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
            o   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  saves,  together  with the market  expansion
opportunities for products, services and new business, provided a unique balance
of  consolidation  and growth which would 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.

INTEREST OF CERTAIN PERSONS IN THE MERGER

         As of [record  date],  directors and officers of American  beneficially
owned, in the aggregate, [942,638] shares of American common stock, representing
approximately [30.12%] 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 [record date],  American  Bancorporation held 1,182 shares of
Wesbanco  common stock.  As of [record date],  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.



                                       33



         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 three 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
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 this 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  definded  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, if any.

         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 three years, and will  automatically
renew for  successive  three year terms unless  written notice of termination is
given by either party at least 90 days prior


                                       34


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 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 six (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


                                       35


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 nine months ended September 30, 2001, American
would have contributed  approximately  14.3% of net interest income and 11.2% 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 one  additional
office that is scheduled to open in January of 2002. It is  anticipated  that at
least five offices of the combined bank will be  consolidated  after the merger.
In  addition,  one  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,  and have
completed the filing of these  applications and notifications  prior to the date
of this  document.  The  approval  of the West  Virginia  Board of  Banking  and
Financial  Institutions  was granted on June 11, 2001. The application  with the
Federal  Reserve was  accepted for filing on November 8, 2001.  The  acquisition
cannot proceed in the absence of the Federal Reserve  approval.  There can be no
assurance  that this  regulatory  approval  will be obtained,  and, if obtained,
there can be no assurance as to the date of such  approval or the absence of any
litigation challenging such approval. Wesbanco and American are not aware of any
other material governmental  approvals or actions that are required prior to the
parties' consummation of the acquisition other than those described below.

         Federal  Reserve Board.  The  acquisition is subject to approval by the
Federal  Reserve Board pursuant to the Bank Holding  Company Act of 1956 and the
Federal   Reserve  Act.   Wesbanco  has  filed  the  required   application  and
notifications  with the Federal  Reserve Board for approval of the  acquisition.
Assuming Federal Reserve Board approval,  the acquisition may not be consummated
until  thirty  days after such  approval,  during  which time the United  States
Department  of Justice  ("DOJ")  may  challenge  the  acquisition  on  antitrust
grounds. With the approval of the Federal Reserve Board and the DOJ, the waiting
period may be reduced to no less than fifteen days. The Federal Reserve Board is
prohibited  from approving any  transaction  under the applicable  statutes that
would result in a monopoly,  or that would be in furtherance of any  combination
or conspiracy to monopolize or to attempt to monopolize  the business of banking
in any part of the United States,  or that may have the effect in any section of
the United States of substantially reducing competition,  or tending to create a
monopoly, or resulting in a restraint of trade, unless the Federal Reserve Board
finds  that  the  anti-competitive   effects  of  the  transaction  are  clearly
outweighed in the public  interest by the probable  effect of the transaction in
meeting the convenience and needs of the communities to be served.



                                       36




         In addition,  in reviewing a transaction under the Bank Holding Company
Act, the Federal  Reserve  Board will  consider  the  financial  and  managerial
resources of the companies and their subsidiary banks. It will also consider the
convenience  and needs of the  communities  to be  served.  Under the  Community
Reinvestment  Act of 1977, the Federal  Reserve Board will take into account the
performance  record of each of Wesbanco and American in meeting the credit needs
of the entire community.  Furthermore,  the Bank Holding Company Act and Federal
Reserve Board regulations  require publication of notice of, and the opportunity
for public comment on, the application submitted by Wesbanco for approval of the
acquisition, and authorize the Federal Reserve Board to hold a public hearing or
meeting in connection  therewith if the Federal  Reserve Board  determines  that
such a hearing or meeting would be appropriate. Any hearing, meeting or comments
from third parties could prolong the review of our application.

         If the DOJ were to  commence  an  antitrust  action,  it would stay the
effectiveness  of Federal  Reserve Board  approval of the  acquisition  unless a
court specifically orders otherwise. In reviewing the acquisition, the DOJ could
analyze the  acquisition's  effect on competition  differently  than the Federal
Reserve  Board.  It is possible that the DOJ could reach a different  conclusion
than the Federal Reserve Board regarding the acquisition's  competitive effects.
In particular, the DOJ may focus on the impact of the acquisition on competition
for loans and other  financial  services to small and middle market  businesses.
Failure of the DOJ to object to the  acquisition may not prevent private persons
or state attorneys general from filing antitrust  actions.  Neither American nor
Wesbanco expects the merger to be challenged on anti-competitive grounds.

         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.
In considering  whether to approve  Wesbanco's right to exercise the option, the
Federal Reserve Board would generally apply the same statutory criteria it would
apply to its consideration of approval of the acquisition.

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/prospectus.

         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 [record date].

         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.

         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 tenth 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.


                                       37


         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 you 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 three 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 three-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:

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

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

         o  the merger is abandoned or rescinded;

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

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

         o  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

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

         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/Prospectus 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


                                       38

determined in accordance with Sections 302 and 1001 (and in certain cases, other
provisions) of the Internal Revenue Code of 1986. 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:

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

         o  pursuant to an effective registration statement; or

         o  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
three-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:

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

         o  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.

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 [__] through [___] of
this Proxy Statement/Prospectus.


                                       39


CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         The  merger  is  conditioned  upon  receipt  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.  The  following
summary of the material federal income tax consequences  expected to result from
the merger is  qualified  in its  entirety by  reference to the full text of the
opinion of Kirkpatrick & Lockhart LLP, including the assumptions upon which that
opinion  is based.  The  opinion  is filed as  Exhibit  8.1 to the  Registration
Statement  of which  this  Proxy  Statement/Prospectus  is a part.  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 IRC.

         No rulings  have been or will be requested  from the  Internal  Revenue
Service  ("IRS") 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  IRS  and  the  IRS 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 the date of this Proxy  Statement/Prospectus 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/Prospectus,  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,  Kirkpatrick & Lockhart LLP
will  render an opinion to  Wesbanco  that the  merger  will have the  following
federal income tax consequences:

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

         o  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;

         o  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 one 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 one
            year or less at the effective time of the merger;

         o  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  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;


                                       40


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

         o  A shareholder  of American  common stock who  exercises  dissenter's
            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/Prospectus  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.

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

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

         o  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
warranties of American, Wesbanco, and AB Corporation.  These representations and
warranties,  which will terminate when the merger becomes effective,  relate to,

         o  the  absence  of change  in the  authorized,  issued or  outstanding

         o  the absence of any  material  increase in the  compensation  or fees
            payable  by  American  or  its   subsidiaries  to  their  respective

            stock;

         o  the  absence of any other  event,  condition  or  development  which
            materially   and   adversely   affects   Wesbanco   or  any  of  its
            subsidiaries'  material  assets,  financial  condition or results of
            operations; and

         o  the absence of knowledge by Wesbanco or any of its  subsidiaries  of
            any such event,  condition or  development  which may  materially or
            adversely effect the material assets, financial condition or results
            of operations of Wesbanco and its subsidiaries.

MUTUAL COVENANTS

         Pursuant to the Merger  Agreement,  American and  Wesbanco  have agreed
that, until the merger becomes  effective or the Merger Agreement is terminated,
whichever occurs first, each will, with some exceptions:

         o  use its best  efforts  to take,  or cause to be taken,  all  actions
            required under the Merger Agreement on its part to be taken so as to
            permit the consummation of the merger at the earliest possible date;

         o  cooperate in furnishing  information  for the preparation and filing
            of the Proxy Statement/Prospectus;

         o  cooperate in the filing of any regulatory  applications with respect
            to the merger; and

         o  advise  the  other  party of any  materially  adverse  change in its
            financial  condition,  assets,  business,  or operations,  or of any
            material changes or inaccuracies in data provided to the other party
            pursuant to the Merger Agreement.

                             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.

         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 one 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 one 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:


                                       51


                (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) 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.

         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 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 one 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/Prospectus, 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 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 three 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:

         o  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.

         o  Neither corporation's shareholders have preemptive rights.

         o  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.

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

         o  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.

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 three years rather than one
year, and at least two annual  meetings  instead of one are required to change a
majority of the Board of Directors.  Furthermore,  due to the smaller  number of
directors  to be elected 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.



                                       56


         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.

         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

         Wesbanco  Common Stock having equal rights and privileges  with respect
         to all other common stock of Wesbanco  issued and outstanding as of the

                  (d) Each share of the common  stock of the  Subsidiary  issued
         and  outstanding  immediately  prior to the Effective  Date of the Bank

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.

         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.

         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

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
respect to such shares,  in a timely manner in  accordance  with the ORC, to the
Agreement,  shall  not vote in favor of the  Agreement,  and have  made  written
demand  for the fair  cash  value  of such  shares  within  ten  (10)  days,  in
accordance  with  Section  1701.85  of the ORC.  The  Objecting  Shares  held by
shareholders who do not become Dissenting  Shareholders  shall be converted into
Wesbanco Common Stock in accordance with Section 6 hereof.

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


                                     A - 9


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, 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

its  customers,  were  entered  into (A) in  accordance  with  prudent  business
practices and all applicable laws,  rules,  regulations and regulatory  policies
and (B) with counter-parties believed to be financially responsible at the time;
and each of them  constitutes  the  valid  and  legally  binding  obligation  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

of Ohio,  Delaware or West  Virginia,  as the case may be,  with full  corporate
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

consummation of the Merger and the Bank Merger and the transactions contemplated
hereby will not,  violate any  provision  of the  Articles of  Incorporation  or

Wesbanco nor any Wesbanco Subs are aware of any facts which would form the basis
of a claim under such bonds.  Neither  Wesbanco nor any  Wesbanco  Subs have any
reason to  believe  that any  fidelity  coverage  will not be  renewed  by their
carriers on substantially the same terms as the existing coverage.

          9.23 ADDITIONAL  COVENANTS.  Except as otherwise  contemplated by this
Agreement, Wesbanco covenants and agrees:

          so as to  permit  the  consummation  of the  Merger  at  the  earliest
          possible  date and to cooperate  fully with the other  parties to that
          end,  and that it will,  in all such  efforts,  give  priority to this
          acquisition of American;

              (b) To deliver to American all Forms 10-K,  10-Q and 8-K filed for

              (c) To promptly advise American of any material adverse change  in
          the financial condition,  assets, businesses or operations of Wesbanco
          or any of its subsidiaries, or any material changes or inaccuracies in

          "acquisition proposal" with respect to Wesbanco received by Wesbanco;


                                     A - 32

          governmental approvals, including but not limited to an application to
          the Federal Reserve Board and the West Virginia  Department of Banking
          for prior  approval  of the  acquisition  of  American  by Wesbanco as
          contemplated  hereunder.  Wesbanco will use its best efforts to obtain
          the  approval  or consent of any  federal,  state or other  regulatory
          agency having  jurisdiction  and of any other party to the extent that
          such  approvals  or consents are required to effect the Merger and the
          transactions  contemplated  hereby or are required with respect to the
          documents described in Section 9.4 hereof; and

              (e)  To  cooperate  with  American  in furnishing such information
          concerning  the  business  of  Wesbanco  and  its  subsidiaries  as is
          reasonably  necessary  or  requested  in order to  prepare  any  Proxy
          Statement to be prepared in connection with the Merger.

          9.24 AUTHORITY TO ISSUE SHARES. The shares of common stock of Wesbanco
to be issued  pursuant to this Agreement will be duly authorized at the time the
Merger is  consummated.  When issued upon the terms and conditions  specified in
this  Agreement,   such  shares  shall  be  validly  issued,   fully  paid,  and
nonassessable.  The  shareholders of Wesbanco have, and will have, no preemptive
rights with respect to the  issuance of the shares of Wesbanco to be  authorized
and issued in the transaction contemplated in this Agreement.

         9.25 REPURCHASE  AGREEMENTS.  With respect to any agreement pursuant to
which  Wesbanco or the Wesbanco  Subs have  purchased  securities  subject to an
agreement to repurchase,  Wesbanco and the Wesbanco Subs have a valid, perfected
first lien or security  interest in or evidence of  ownership in book entry form
of the  government  securities  or  other  collateral  securing  the  repurchase
agreement,  and the value of such collateral equals or exceeds the amount of the
debt secured thereby.

         9.26 RISK  MANAGEMENT  INSTRUMENTS.  All material  interest rate swaps,
caps, floors, option agreements, mortgage backed securities, futures and forward
contracts and other similar risk management  arrangements,  whether entered into
for Wesbanco's or the Wesbanco  Subs' own account,  or for the account of one


                                     A - 33


or more of its  customers,  were  entered  into (A) in  accordance  with prudent
business  practices and all applicable laws,  rules,  regulations and regulatory
policies and (B) with counter-parties  believed to be financially responsible at
the time; and each of them constitutes the valid and legally binding  obligation
of Wesbanco or the Wesbanco Subs  enforceable in accordance with its terms,  and
is in full force and effect.  Wesbanco  and the  Wesbanco  Subs are not,  nor to
Wesbanco's  knowledge  is any  other  party  thereto,  in  breach  of any of its
obligations under any such agreement or arrangement.

regulation,  or  order  of  any  regulatory  body,  and  further  provided  that
confidential   information  of  individual   banking   customers  shall  not  be
photocopied  or removed  from the  premises  of such  institution.  All data and

                  constitute  a  reorganization  within  the  meaning of Section
                  368(a)(1) of the Internal  Revenue Code of 1986  ("IRC"),  and
                  Wesbanco,  American,  AB and Bank  will  each be a "party to a
                  reorganization" as defined in IRC Section 368(b);

                           (ii)  No gain or loss will be recognized by Wesbanco,
                  American,   AB  or   Bank  as a  result  of  the  transactions
                  contemplated in the Agreement;

                           (iii)  No  gain or loss  will  be  recognized  by the
                  shareholders  of  American  as a result of their  exchange  of
                  American's Common Stock for Wesbanco's Common Stock, except to
                  the  extent  any  shareholder  receives  cash  in  lieu  of  a
                  fractional share or as a dissenting shareholder;


                                     A - 36



                           (iv) The holding period of the Wesbanco  Common Stock
                  received by each holder of American  Common Stock will include
                  the period during which the stock of American  surrendered  in
                  exchange therefor was held,  provided such stock was a capital
                  asset in the hands of the holder on the date of exchange; and

                           (v) The  Federal  Income  Tax  basis of the  Wesbanco
                  Common Stock received by each holder of American  Common Stock
                  will  be  the  same  as  the  basis  of  the  stock  exchanged
                  therefore.

                  (k) No action,  proceeding,  regulation or  legislation  shall
         have  been  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 threat of material  litigation or proceeding,  regardless
         of whether  such request is received  before or after  execution of the
         Agreement).

                  (l) The approvals  referred to in subparagraphs (b) and (d) of
         Subsection  12.1 herein  shall not have  required  the  divestiture  or
         cessation of any significant part of the present  operations  conducted
         by Wesbanco, American or any of their subsidiaries,  and shall not have
         imposed any other condition, which divestiture,  cessation or condition
         Wesbanco   reasonably  deems  to  be  materially   disadvantageous   or
         burdensome.

          12.2  CONDITIONS  PRECEDENT  OF  WESBANCO.  The  consummation  of this
Agreement by Wesbanco and the Merger is also conditioned upon the following:

                  (a)  Unless  waived  by  Wesbanco,   the  representations  and
         warranties of American  contained in this Agreement shall be correct on
         and as of the 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 its  Subsidiary


                                     A - 37


         taken as a whole,  or which are the result of expenses or  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 by one or more appropriate  executive officers of
         American  to the effect that such  officers  have no  knowledge  of the
         nonfulfillment of the foregoing condition;

                  (b)  OPINION  OF  AMERICAN  COUNSEL.  An  opinion of Robert P.
         Fitzsimmons,  counsel  for  American,  shall  have  been  delivered  to
         Wesbanco,   dated  the  Closing   Date,   and  in  form  and  substance
         satisfactory to Wesbanco and its counsel, to the effect that:

                           (i) 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.

                           (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


                                     A - 38


                  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.

                           (v)  American's  Subsidiary  is  a  national  banking
                  association  and is duly  organized,  validly  existing and in
                  good standing under the laws of the United States,  and it has
                  the requisite  corporate  power and authority to own and lease
                  its  properties and to conduct its business as it is now being
                  conducted.  To the best of such counsel's  knowledge  American
                  owns  100%  of  the  issued  and  outstanding  stock  of  such
                  corporation.

                           (vi) To the best of such counsel's  knowledge,  as of
                  the  date  hereof  neither  American  nor its  Subsidiary  was
                  involved  in  any  litigation   against  them  (with  possible
                  exposure of $100,000.00 or more), pending or threatened.

                  (c) Jeremy C. McCamic and Paul W. Donahie  shall have resigned
         as officers of American and its Subsidiary, which resignations shall be
         dated as of the Closing Date,  shall have each executed  severance plan
         clarification agreements in form and substance satisfactory to Wesbanco
         and  have  executed   Consulting   Agreements  in  form  and  substance
         satisfactory to Wesbanco. Brent E. Richmond and John E. Wait shall have
         duly executed and delivered the  employment  agreements  with the Bank,
         dated as of the Closing Date, in substantially the form attached hereto
         as  Exhibits  ____ and _____,  and Brent E.  Richmond  and John E. Wait
         shall each have executed  severance plan  clarification  agreements and
         Patrick G.  O'Brien  shall have  executed an  Amendment  to  Employment
         Agreement, each in form and substance satisfactory to Wesbanco.

                  (d)  American  shall  have  delivered  to  Wesbanco a schedule
         identifying  all  persons  who  may be  deemed  to be  "affiliates"  of
         American under Rule 145 of the Securities Act of 1933, as amended,  and
         shall use its best  efforts  to cause  each  affiliate  to  deliver  to
         Wesbanco prior to the Effective Date a letter substantially in the form
         attached hereto as Exhibit A.

                  (e) American  shall have  furnished  Wesbanco with a certified
         copy of  resolutions  duly  adopted by the Board of  Directors  and the
         shareholders  of American  approving the Agreement and  authorizing the
         Merger and the transactions contemplated hereby.


                                     A - 39


                  (f) Unless  waived by  Wesbanco,  on the Closing  Date,  there
         shall not be 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 proceeding  which,  in the reasonable  judgment of
         Wesbanco,  if  successful,  would have material  adverse  effect on the
         financial condition or operations of American or its Subsidiary.

                  (g) American  shall have  executed and delivered to Wesbanco a
         Stock Option  Agreement,  substantially  in the form attached hereto as
         Exhibit B, dated the date of this Agreement, and incorporated herein by
         reference.

         12.3  CONDITIONS  PRECEDENT  OF  AMERICAN.  The  consummation  of  this
Agreement by American and the Merger is also conditioned upon the following:

                  (a)  Unless  waived  by  American  the   representations   and
         warranties  of Wesbanco  and AB contained  in this  Agreement  shall be
         correct on and as of the 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  American  or which  are not in the
         aggregate material and adverse to the financial condition,  businesses,
         properties  or operations of Wesbanco and AB or which are the result of
         expenses or  transactions  contemplated or permitted by this Agreement,
         and Wesbanco and AB shall have  performed in all material  respects all
         of  their  obligations  and  agreements  hereunder  theretofore  to  be
         performed by them;  and American  shall have  received on the Effective
         Date an appropriate certificate (in affidavit form) dated the Effective
         Date  and  executed  on  behalf  of  Wesbanco  and AB by  one  or  more
         appropriate  executive officers of each of them to the effect that such
         officers  have no  knowledge  of the  nonfulfillment  of the  foregoing
         conditions;

                  (b)  OPINION OF  WESBANCO  COUNSEL.  An  opinion of  Phillips,
         Gardill,  Kaiser &  Altmeyer,  counsel  for  Wesbanco,  shall have been
         delivered  to  American,  dated  the  Closing  Date,  and in  form  and
         substance satisfactory to American and its counsel, to the effect that:

                           (i)  Wesbanco,  AB and  Bank  are  corporations  duly
                  organized,  validly  existing and in good  standing  under the
                  laws of the State of West Virginia and have the full corporate
                  power and authority to own all of their  properties and assets
                  and to  carry  on  their  businesses


                                     A - 40


                  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 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,  AB
                  and Bank, taken as a whole.

                           (ii)  Wesbanco,  AB and Bank have the full  corporate
                  power to execute  and  deliver the  Agreement.  All  corporate
                  action of Wesbanco, AB and Bank required to duly authorize the
                  Agreement  and the  actions  contemplated  thereby  have  been
                  taken, and the Agreement is valid and binding on Wesbanco,  AB
                  and Bank in  accordance  with its  terms,  subject,  as to the
                  enforcement of remedies, to applicable bankruptcy, insolvency,
                  moratorium, or other similar laws affecting the enforcement of
                  creditors'  rights generally from time to time in effect,  and
                  subject  to any  equitable  principles  limiting  the right to
                  obtain specific performance of certain obligations thereunder.

                           (iii) The consummation of the mergers contemplated by
                  the Agreement  will not violate any  provision of  Wesbanco's,
                  AB's or Bank'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 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 are subject which
                  would have a material  adverse effect on the assets,  business
                  or operations of Wesbanco, AB and Bank taken as a whole.

                           (iv)  Each  of   Wesbanco's   subsidiaries   is  duly
                  organized,  validly  existing and in good  standing  under the
                  laws of the state of its  organization  and has the  requisite
                  corporate  power and authority to own and lease its properties
                  and to conduct its business as it is now being  conducted.  To
                  the best of such  counsel's  knowledge,  Wesbanco owns 100% of
                  the issued and outstanding stock of each such corporation.

                           (v) To the best of such  counsel's  knowledge,  as of
                  the date hereof,  neither Wesbanco nor any of its subsidiaries
                  were involved in any  litigation  against them (with  possible
                  exposure of $100,000.00 or more), pending or threatened,  that
                  has not been disclosed to American.

                           (vi) The shares of Wesbanco Common Stock to be issued
                  to American's  shareholders  pursuant to the  Agreement,  when
                  issued as described therein, will be duly authorized,  validly
                  issued, fully paid and nonassessable.

                  (c) McDonald Investments Inc., financial advisors to American,
         shall have  furnished  to American  an  opinion,  or an updating of any
         opinion rendered after the date of the Agreement,  dated on or prior to
         the distribution date of the Proxy Statement  described


                                     A - 41



         in Section  14.1 of this  Agreement,  to the effect  that the  exchange
         ratio is fair,  from a financial point of view, as of such date, to the
         shareholders of American.

                  (d) Wesbanco,  AB and Bank shall have furnished  American with
         certified copies of resolutions duly adopted by the Boards of Directors
         of Wesbanco,  AB and Bank and the shareholders of Wesbanco, AB and Bank
         approving the Agreement and authorizing the Merger, the Bank Merger and
         transactions contemplated hereby.

                  (e) Unless  waived by  American,  on the Closing  Date,  there
         shall not be pending against Wesbanco or any of its subsidiaries or the
         officers or directors of Wesbanco or any of its  subsidiaries  in their
         capacity  as  such,  any  suit,  action  or  proceeding  which,  in the
         reasonable judgment of American,  if successful,  would have a material
         adverse effect on the financial  condition or operations of Wesbanco or
         any of its subsidiaries.

         12.4 CLOSING DATE. The Closing shall be effected as soon as practicable
after all of the  conditions  contained  herein shall have been satisfied on the
Closing Date as defined in Section 2.3 hereof,  which  Closing Date shall be the
latest of:

         shareholders of American or Wesbanco,  whichever is later, at which the
         Agreement is approved;

                  (b)  The  fifteenth  (15th)  day  after  the  approval  of the
         acquisition  of  American  by the  Board of  Governors  of the  Federal
         Reserve System (the "Federal Reserve Board");

                  (d) The day  after  any stay of the  Federal  Reserve  Board's
         approval of the  acquisition  of  American or the  approval of the Bank
         Merger  shall be  vacated  or shall  have  expired or the day after any

                             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:





                                     C - 1


                           (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  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


                                     C - 2



         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  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


                                     C - 3



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.

         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


                                     C - 4



         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 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

         consultants, investment bankers, accountants and counsel.


                                     C - 5



                  b. ENTIRE AGREEMENT.  Except as otherwise  expressly  provided
         herein, this Option Agreement contains the entire agreement between the
         parties with respect to the  transactions  contemplated  hereunder  and
         supersedes  all  prior  arrangements  or  understandings  with  respect
         thereto,  written  or oral.  The terms and  conditions  of this  Option
         Agreement shall inure to the benefit of and be binding upon the parties
         hereto and their  respective  successors  and assigns.  Nothing in this
         Option Agreement,  expressed or implied, is intended to confer upon any
         party, other than the parties hereto,  and their respective  successors
         and assigns, any rights, remedies,  obligations or liabilities under or
         by reason  of this  Option  Agreement,  except  as  expressly  provided
         herein.

                  c. ASSIGNMENT. Neither of the parties hereto may assign any of
         its rights or  obligations  under this Option  Agreement  or the Option
         created  hereunder  to any other  person,  without the express  written
         consent of the other party.

                  d.  NOTICES.  All  notices or other  communications  which are
         required or permitted  hereunder  shall be in writing and sufficient if
         delivered  in  the  manner  and  to the  addresses  provided  for in or
         pursuant to Section 18 of 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 either party hereto through  injunctive or other  equitable
         relief.

                  g. GOVERNING LAW. This Option  Agreement  shall be governed by
         and construed in accordance with the laws of the State of West Virginia
         applicable to agreements made and entirely to be performed  within such
         state and such federal laws as may be applicable.

         IN WITNESS WHEREOF, each of the parties hereto has executed this Option
Agreement as of the day and year first written above.

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;

     (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.

         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,

                                                                         ANNEX E

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


                                     E - 1


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 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.

         (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


                                     E - 2



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.

                                     PART II

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers.

    Wesbanco's  Bylaws  provide,  and West Virginia law permits (W. Va. Code ss.
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. Codess.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  determine  upon
application that, despite the adjudication



                                      II-1




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.

                  Shareholders (filed herewith).


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 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.
