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 _____.

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.

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.

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

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.

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

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:

                                                       AMERICAN

 Last twelve months earnings with cost savings (1)        14.8%
 Projected year 1 earnings with cost savings (1)          16.1%

 PRO FORMA OWNERSHIP                                      16.1%

(1) Includes  estimated  cost savings of 31% of American's  last
twelve months'  non-interest  expense base  attributable  to the
merger; excludes one-time charges.

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

Transactions");

(2) Last twelve  months  fully-diluted  earnings  per share  (assuming  Treasury
    method of accounting for stock options).
(3) Premium over tangible book value as a percentage of core deposits.

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

Comparable Company Analysis: McDonald reviewed and compared stock market data and selected financial information for Wesbanco as of November 30, 2001 with corresponding information for actively-traded banks possessing similar financial and performance characteristics as Wesbanco. The comparison banks were grouped according to the criteria listed below:

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;

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.

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

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

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.

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.

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

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.

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;

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.

CONDITIONS TO OBLIGATIONS OF AMERICAN

The consummation of the merger by American is also conditioned upon the absence of any suit, action, or proceeding pending against Wesbanco or any of its subsidiaries or the officers or directors of Wesbanco or of any of its subsidiaries in their capacity as such, which, in the reasonable judgment of American would, if successful, have a materially adverse effect on the financial condition or operations of Wesbanco or any of its subsidiaries.

TERMINATION; EXPENSES

The Merger Agreement may be terminated at any time prior to the closing of the merger, either before or after the Special Meeting of American shareholders:

o by mutual consent of American and Wesbanco;

o by either American or Wesbanco if any of the conditions to such party's obligations to close under the Merger Agreement have not been met as of the date the merger is to close and such conditions have not been waived by the party adversely affected thereby;

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

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

AMENDMENT OR WAIVER

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

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

STOCK OPTION AGREEMENT

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

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:

(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.

(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.

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

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

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

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.

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

ANNEX C

STOCK OPTION AGREEMENT

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

WITNESSETH:

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

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

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

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

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

3. EXERCISE OF OPTION.

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

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

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

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

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

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

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

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

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

any required notification period has expired or been terminated or such approval has been obtained and any requisite waiting period shall have passed.

4. PAYMENT AND DELIVERY OF CERTIFICATES.

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

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

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

"The transfer of the shares represented by this certificate is subject to certain provisions of an agreement between the registered holder hereof and American Bancorporation and to resale restrictions arising under the Securities Act of 1933, as amended, a copy of which agreement is on file at the principal office of American Bancorporation. A copy of such agreement will be provided to the holder hereof without charge upon receipt by American Bancorporation of a written request."

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

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

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

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

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

7. REGISTRATION RIGHTS. American shall, if requested by Wesbanco, as expeditiously as possible file a registration statement on a form of general use under the Securities Act if necessary in order to permit the sale or

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

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

9. PUT-BACK RIGHTS.

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

b. Wesbanco may exercise its right to require American to repurchase the Option pursuant to this Section 9 by giving American written notice of its exercise of its repurchase right in accordance with the provisions of this Section 9. Subject to the last proviso of paragraph 9(c) below, as promptly as practicable, and in any event within five business days after the receipt of such notice or notices relating thereto, American shall

deliver or cause to be delivered to Wesbanco the Repurchase Price for the Option or the portion thereof which American is not then prohibited under applicable law and regulation from so delivering.

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

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

11. MISCELLANEOUS.

a. EXPENSES. Except as otherwise provided herein, each of the parties hereto shall bear and pay all costs and expenses incurred by it or on its behalf in connection with the transactions contemplated hereunder, including fees and expenses of its own financial consultants, investment bankers, accountants and counsel.

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.

The terms and conditions of the Merger are more fully set forth in the Agreement.

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,

Effective date: 10-4-1996

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

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

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

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

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

(5) If the corporation sends to the dissenting shareholder, at the address specified in his demand, a request for

the certificates representing the shares as to which he seeks relief, the dissenting shareholder, within fifteen days from the date of the sending of such request, shall deliver to the corporation the certificates requested so that the corporation may forthwith endorse on them a legend to the effect that demand for the 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

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.

Effective date: 7-1-1994
