(3) Consists of funds provided with the specific requirement that they be used by the officer to obtain an equity interest in SWVA by purchasing shares of SWVA common stock.

Employment Agreement. The Savings Bank maintains an employment agreement with D. W. Shilling, President and Chief Executive Officer of the Savings Bank. The employment agreement is for a term of three years at his then current salary level. The employment agreement is terminable by the Savings Bank for "just cause" as defined in the employment agreement. If the Savings Bank terminates Mr. Shilling without just cause, he will be entitled to a continuation of his salary from the date of termination through the remaining term of the employment agreement, but in no event for a period of less than 12 months. The employment agreement contains a provision stating that in the event of his involuntary termination of employment in connection with, or within two years after, any change in control of the Savings Bank, Mr. Shilling will be paid in a lump sum an amount equal to 2.999 times his average annual compensation for the prior five years. Following a change in control, a termination of employment as of June 30, 2000, would have resulted in a lump sum payment of approximately $315,000 to Mr. Shilling. The employment agreement may be renewed annually by the Board of Directors upon a determination of satisfactory performance.

Certain Relationships and Related Transactions. Except as noted below, no directors, executive officers, or immediate family members of such individuals were engaged in transactions with the Savings Bank or any subsidiary involving more than $60,000 during the fiscal year ended June 30, 2000. Furthermore, the Savings Bank had no "interlocking" relationships existing on or after June 30, 2000, in which (1) any executive officer is a member of the Board of Directors/Trustees of another entity, one of whose executive officers is a member of the Savings Bank's Board of Directors, or where (2) any executive officer is a member of the compensation committee of another entity, one of whose executive officers is a member of the Savings Bank's Board of Directors.

Set forth below is certain information as of June 30, 2000, relating to mortgage and other loans given to executive officers and directors and their immediate family who had aggregate outstanding loan balances with the Savings Bank of $60,000 or greater.

The Savings Bank, like many financial institutions, has followed a policy of granting various types of loans to officers, directors, and employees. Such loans have been made in the ordinary course of business and on substantially the same terms, including interest rates and collateral as those prevailing at the time for comparable transactions with the Savings Bank's other customers, and do not involve more than the normal risk of collectability, nor present other unfavorable features. However, as part of the Savings Bank's compensation program, the Savings Bank makes adjustable-rate first mortgage loans to full- time employees, officers, directors and related parties at 1% above the Savings Bank's cost of funds while adjustable-rate second mortgages and cash out refinances are made at 1.5% above the Savings Bank's cost of funds. Such rates are only effective while such persons are employees, officers, and/or directors (including loans to related parties of such individuals) of the Savings Bank and continue to occupy the real estate securing the loans as their primary residence.

(1) The interest rate of 5.75% on the home mortgage loan is an adjustable rate mortgage plan. The loan was modified at the time the loan was made to 1% above the cost of Savings Bank's funds rounded to the next one-quarter percent. The rate on this loan adjusts annually. The loan was originated with a 5.5% interest rate.

Cherry Bekaert & Holland L.L.P. served as SWVA's auditors for the fiscal year ended June 30, 2000. The Board of Directors has approved the selection of Cherry Bekaert & Holland L.L.P. as its auditors for the fiscal year ended June 30, 2001, subject to ratification by SWVA's shareholders. A representative of Cherry Bekaert & Holland L.L.P. is expected to be present at the meeting to respond to shareholders' questions and will have the opportunity to make a statement if he or she so desires.

The Board of Directors recommends that shareholders vote "FOR" the ratification of the appointment of Cherry Bekaert & Holland L.L.P. as SWVA's auditors for the fiscal year ended June 30, 2001.

The Companies

SWVA

SWVA is a Virginia-chartered corporation organized in June of 1994, at the direction of Southwest Virginia Savings Bank, FSB to acquire all of the capital stock that the Bank issued in its conversion from the mutual to stock form of ownership. On October 7, 1994, the Savings Bank completed the conversion and became a wholly owned subsidiary of SWVA. In connection with the conversion, SWVA issued 570,590 shares of its common stock, par value $.10 per share. SWVA is a unitary savings and loan holding company which, under existing laws, generally is not restricted in the types of business activities in which it may engage provided that the Savings Bank retains a specified amount of its assets in housing-related investments.

The Savings Bank is primarily engaged in attracting deposits from the general public and using those funds to originate real estate loans on one- to four-family residences and, to a lesser extent, construction, multi-family and non-residential real estate loans, commercial loans and consumer loans. In addition, the Savings Bank invests in investments securities and mortgage-backed securities. The Savings Bank offers its customers both ARMs and fixed-rate mortgage loans. ARMs are originated for retention in the Savings Bank's portfolio. Generally, the Savings Bank sells fixed rate mortgage loans upon origination in the secondary market. Depending on the level of prevailing interest rates, the Savings Bank may retain fixed rate mortgage loans in its portfolio. Management of the Savings Bank determines whether to retain fixed rate mortgage loans in its portfolio over the average life of the loan. All commercial and consumer loans are retained in the Savings Bank's portfolio and management anticipates that the future focus on these types of loans will generate new business that will enable the Savings Bank to reduce its dependence on mortgage activity.

The principal sources of funds for the Savings Bank's lending activities are deposits and the amortization, repayment and maturity of loans, investments and mortgaged-backed securities. The Savings Bank's primary sources of income are interest and fees on loans, interest on investments and mortgage-backed securities and customer service fees. The Savings Bank's primary expense is interest paid on deposits.

The Savings Bank's primary market area consists of Roanoke County, the City of Roanoke, the City of Salem, and the County of Botetourt. The Savings Bank regards this area as its "basic" lending area, but loans are also made in the adjoining counties of Bedford and Franklin.

The Savings Bank's main office is located at 302 Second Street, S.W., in the City of Roanoke, Virginia. The Savings Bank has one branch office located in the City of Roanoke. The Savings Bank has another branch and a loan production office located in Roanoke County, as well as branch offices in Vinton and Salem, Virginia.

The Roanoke Valley is equidistant from New York and Atlanta, 230 miles south of Washington, D.C. and 250 miles west of the Port of Hampton Roads, Virginia. The population in the Roanoke Valley area has remained relatively stable over the past thirty years and was 269,100 according to the 1990 U.S. Census. The Roanoke Valley area enjoys a diversified economy comprised of services, retail, manufacturing, government offices, finance, insurance, real estate, wholesale trade, transportation, public utilities, construction and agriculture.

The outlying region of the Savings Bank's market area is rural in nature and may represent limited opportunities for lending and investment growth which could adversely affect the Savings Bank's ability to achieve asset growth. The Savings Bank is the only savings bank headquartered in the Roanoke Valley area. This area is also served by branch offices of regional commercial banks and various community banks and credit unions.

FNB

Subsequent to December 31, 1995, the Board of Directors of First National Bank approved a reorganization whereby a bank holding company (FNB Corporation) was incorporated under the laws of the Commonwealth of Virginia. On June 11, 1996, the shareholders of the Bank approved a plan for the holding company to exchange one share of its stock for each share of stock of the Bank. A registration statement was filed with the SEC to register the stock of the holding company, and such registration statement was subsequently declared effective by the SEC. On July 11, 1996, the OCC approved the plan, and the exchange was subsequently consummated. As a result, the Bank became a wholly owned subsidiary of the holding company during the third quarter of 1996, and the holding company began filing periodic reports under the Securities Exchange Act of 1934. Prior to the consummation of the exchange, the Bank filed periodic reports with the OCC.

First National Bank. First National Bank, which was organized in 1905, does a general banking business, serving the commercial, agricultural, and personal banking needs of its trade territory, commonly referred to as the New River Valley, which consists of Montgomery County, Virginia and portions of surrounding counties. The Bank engages in and offers a full range of banking services, including trust services; demand, savings, and time deposits used to fund the loan demand in its trade area; commercial, farm, consumer installment, mortgage, credit card, FHA and SBA guaranteed loans.

Under national banking law, nontraditional activities of a bank must be operated through a corporate subsidiary of the bank. During 1992, FNB formed a wholly-owned subsidiary in order to expand its business operations. FNB Financial Services, Inc. is a member of the Virginia Title Center, L.L.C. and acts as an agent in the issuance of title insurance policies. Additionally, this subsidiary has been licensed by the Commonwealth of Virginia to offer annuity products through First National's Trust Department.

The local economy is tied primarily to the area's three largest employers
- Virginia Polytechnic Institute and State University, with a student population in excess of 25,000; Radford University, with a student population in excess of 8,000; and the Radford Arsenal, a large munitions plant operated under contract to the U.S. Army by the Hercules Corporation. Other industries include a wide variety of manufacturing concerns and agriculture-related enterprises. The Bank's main office is located in Christiansburg, the County Seat, with offices strategically located to take advantage of its trade area's population mix. Of the Bank's twelve full service offices, nine are located in Montgomery County, one in the City of Radford, one in the Town of Dublin and one in Wythe County. One paying and receiving office is located in Montgomery County.

Competition. FNB is the largest bank in the area, with approximately 60% of those deposits held by independent banks. It is estimated that FNB holds 36% of total deposits in its primary trade area including the offices of those state-wide and multi-state bank holding companies located in its trade area. Competition in the trade area consists of state-wide and multi-state bank holding companies, independent banks, and credit unions.

Loan Commitments. The Bank's portfolio is not concentrated within any single industry or group of related industries, nor is there any material risk other than that which is expected in the normal course of business of a bank in this location. Bank policy establishes lending limits for each officer. Loan requests for amounts exceeding loan officer lending authority are referred to the officer loan committee which can approve loans up to 80% of the Bank's legal lending limit. Loan requests exceeding this limit are referred to the Executive Committee of the Board of Directors.

Description of FNB Capital Stock

The information below outlines some provisions of FNB's articles of incorporation and bylaws and the Virginia Stock Corporation Act. The information is qualified in all respects by reference to the provisions of FNB's articles of incorporation and bylaws, which are incorporated by reference as exhibits to the registration statement, and the Virginia Business Corporation Act. See "Available Information."

47

Common Stock

FNB's articles of incorporation authorized the issuance of up to ten million shares of common stock, par value $5.00 per share.

Dividends. The holders of FNB common stock are entitled to share ratably in dividends when and if declared by the FNB Board from funds legally available therefor.

Voting Rights. Each holder of FNB common stock has one vote for each share held on matters presented for consideration by the shareholders.

Classification of Board of Directors. The FNB Board is divided into three classes, each serving three-year terms, so that approximately one-third of the directors of FNB are elected at each annual meeting of the shareholders of FNB. Classification of the FNB Board has the effect of decreasing the number of directors that could be elected in a single year by any person who seeks to elect its designees to a majority of the seats on the FNB Board and thereby could impede a change in control of FNB.

Preemptive Rights. The holders of FNB common stock have no preemptive rights to acquire any additional shares of FNB Common Stock.

Issuance of Stock. FNB's articles of incorporation authorize the FNB Board to issue authorized shares of FNB common stock without shareholder approval. However, FNB's common stock is listed on the NASDAQ National Market System, which requires shareholder approval of the issuance of additional shares of FNB common stock under some circumstances.

Liquidation Rights. In the event of liquidation, dissolution or winding- up of FNB, whether voluntary or involuntary, the holders of FNB common stock will be entitled to share ratably in any of its assets or funds that are available for distribution to its shareholders after the satisfaction of its liabilities (or after adequate provision is made therefor).

Control Acquisitions. The Federal Change in Bank Control Act of 1978, as amended, prohibits a person or group of persons from acquiring "control" of a bank holding company unless the Federal Reserve Board has been given 60 days' prior written notice of such proposed acquisition and within that time period the Federal Reserve Board has not issued a notice disapproving the proposed acquisition or extending for up to another 30 days the period during which such a disapproval may be issued. An acquisition may be made prior to the expiration of the disapproval period if the Federal Reserve Board issues written notice of its intent not to disapprove the action. Under a rebuttable presumption established by the Federal Reserve Board, the acquisition of more than 10% of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act would, under the circumstances set forth in the presumption, constitute the acquisition of control.

In addition, any "company" would be required to obtain the approval of the Federal Reserve Board under the BHC Act before acquiring 25% (5% in the case of an acquirer that is a bank holding company) or more of the outstanding shares of FNB common stock, or such lesser number of shares as constitute control over FNB.

State Anti-Takeover Statutes

The Virginia Stock Corporation Act restricts transactions between a corporation and its affiliates and potential acquirors. The summary below is necessarily general and is not intended to be a complete description of all the features and consequences of those provisions, and is qualified in its entirety by reference to the statutory provisions contained in the Virginia Stock Corporation Act. Because both SWVA and FNB are Virginia corporations, the provisions of the Virginia Stock Corporation Act described below apply to SWVA and FNB and will continue to apply to FNB after the merger.

Affiliated Transactions. The Virginia Stock Corporation Act contains provisions governing "Affiliated Transactions," found at Sections 13.1-725 - 727.1 of the Virginia Stock Corporation Act. Affiliated Transactions include certain affiliations and share exchanges, certain material dispositions of corporate assets not in the ordinary course of business, any dissolution of a corporation proposed by or on behalf of an Interested Shareholder (as defined below), and reclassifications, including reverse stock splits, recapitalizations or affiliations of a corporation with its subsidiaries, or distributions or other transactions which have the effect of increasing the percentage of voting shares beneficially owned by an Interested Shareholder by more than 5%. For purposes of the Virginia Stock Corporation Act, an "Interested Shareholder" is defined as any beneficial owner of more than 10% of any class of the voting securities of a Virginia corporation.

Subject to certain exceptions discussed below, the provisions governing Affiliated Transactions require that, for three years following the date upon which any shareholder becomes an Interested Shareholder, any Affiliated Transaction must be approved by the affirmative vote of holders of two-thirds of the outstanding shares of the corporation entitled to vote, other than the shares beneficially owned by the Interested Shareholder, and by a majority (but not less than two) of the Disinterested Directors (as defined below). A "Disinterested Director" is defined in the Virginia Stock Corporation Act as a member of a corporation's board of directors who (1) was a member before the later of January 1, 1988 or the date on which a shareholder became an Interested Shareholder and (2) was recommended for election by, or was elected to fill a vacancy and received the affirmative vote of, a majority of the Disinterested Directors then on the corporation's board of directors. At the expiration of the three year period after a shareholder becomes an Interested Shareholder, these provisions require approval of the Affiliated Transaction by the affirmative vote of the holders of two-thirds of the outstanding shares of the corporation entitled to vote, other than those beneficially owned by the Interested Shareholder.

The principal exceptions to the special voting requirement apply to Affiliated Transactions occurring after the three year period has expired and require either that the transaction be approved by a majority of the corporation's Disinterested Directors or that the transaction satisfy certain fair price requirements of the statute. In general, the fair price requirements provide that the shareholders must receive the higher of: the highest per share price for their shares as was paid by the Interested Shareholder for his or its shares, or the fair market value of the shares. The fair price requirements also require that, during the three years preceding the announcement of the proposed Affiliated Transaction, all required dividends have been paid and no special financial accommodations have been accorded the Interested Shareholder, unless approved by a majority of the Disinterested Directors.

None of the foregoing limitations and special voting requirements applies to a transaction with an Interested Shareholder who has been an Interested Shareholder continuously since the effective date of the statute (January 26, 1988) or who became an Interested Shareholder by gift or inheritance from such a person or whose acquisition of shares making such person an Interested Shareholder was approved by a majority of the Disinterested Directors of the corporation.

49

These provisions were designed to deter certain takeovers of Virginia corporations. In addition, the Virginia Stock Corporation Act provides that by affirmative vote of a majority of the voting shares other than shares owned by any Interested Shareholder, a corporation may adopt by meeting certain voting requirements, an amendment to its articles of incorporation or bylaws providing that the Affiliated Transactions provisions shall not apply to the corporation. Neither SWVA nor FNB has adopted such an amendment. Currently, no shareholder of SWVA owns or controls 10% or more of SWVA common stock, and there are no Interested Shareholders of SWVA or FNB as defined by the Virginia Stock Corporation Act.

Control Share Acquisitions. The Virginia Control Share Acquisitions statute, found at Sections 13.1-728 - 728.8 of the Virginia Stock Corporation Act, also is designed to afford shareholders of a public company incorporated in Virginia protection against certain types of non-negotiated acquisitions in which a person, entity or group (Acquiring Person) seeks to gain voting control of that corporation. With certain enumerated exceptions, the statute applies to acquisitions of shares of a corporation which would result in an Acquiring Person's ownership of the corporation's shares entitled to vote in the election of directors falling within any one of the following ranges: 20% to 33-13%, 33- 13% to 50% or 50% or more (a Control Share Acquisition). Shares that are the subject of a Control Share Acquisition (Control Shares) will not be entitled to voting rights unless the holders of a majority of the "Disinterested Shares" vote at an annual or special meeting of shareholders of the corporation to accord the Control Shares with voting rights. Disinterested shares do not include shares owned by the Acquiring Person or by officers and inside directors of the target company. Under certain circumstances, the statute permits an Acquiring Person to call a special shareholders' meeting for the purpose of considering granting voting rights to the holders of the Control Shares. As a condition to having this matter considered at either an annual or special meeting, the Acquiring Person must provide shareholders with detailed disclosures about his identity, the method and financing of the Control Share Acquisition and any plans to engage in certain transactions with, or to make fundamental changes to, the corporation, its management or business. Under certain circumstances, the statute grants dissenters' rights to shareholders who vote against granting voting rights to the Control Shares. The Virginia Control Share Acquisitions Statute also enables a corporation to make provisions for redemption of Control Shares with no voting rights. Among the acquisitions specifically excluded from the statute are acquisitions which are a part of certain negotiated transactions to which the corporation is a party and which, in the case of mergers or share exchanges, have been approved by the corporation's shareholders under other provisions of the Virginia Stock Corporation Act.

Listing of FNB Common Stock

The FNB common stock is traded on the NASDAQ National Market System under the symbol "FNBP." FNB will obtain approval from NASDAQ for listing of additional shares of FNB common stock to be issued as a result of the merger.

Differences in the Rights of FNB Shareholders and SWVA Shareholders

General

FNB and SWVA are incorporated under the laws of Virginia and, accordingly, the rights of SWVA's shareholders and FNB's shareholders are governed by the laws of the Commonwealth of Virginia. In addition, as a result of the merger, SWVA shareholders automatically will become shareholders of FNB to the extent that they elect and receive stock consideration in the merger, and their rights as shareholders will be determined by the articles of incorporation and bylaws of FNB and the Virginia Stock Corporation Act, instead of by the articles of incorporation and bylaws of SWVA. The following summarizes the material differences in the rights of shareholders of FNB and SWVA. This summary is necessarily general, and is qualified in its entirety by reference to, the Virginia Stock Corporation Act and the articles of incorporation and bylaws of each corporation.

Regulation

Set forth below is a brief description of some laws and regulations that relate to the regulation of FNB and SWVA. The description of these laws and regulations, as well as descriptions of laws and regulations contained elsewhere herein, is qualified in its entirety by reference to applicable laws and regulations.

General

FNB is a bank holding company within the meaning of the Bank Holding Company Act of 1956. SWVA is a unitary savings and loan holding company under the Home Owners' Loan Act. FNB is supervised by the Board of Governors of the Federal Reserve System and are required to file reports with the Federal Reserve and provide such additional information as the Federal Reserve may require. SWVA is supervised by the Office of Thrift Supervision and is required to file reports with the OTS and provide such additional information as the OTS may require. First National Bank, the banking subsidiary of FNB is a national banking association and as such it is regulated by the Office of the Comptroller of the Currency. The OCC conducts regular examinations of national banks, reviewing such matters as the adequacy of loan loss reserves, quality of loans and investments, management practices, compliance with laws, and other aspects of their operations. In addition to these regular examinations, national banks must furnish the OCC with periodic reports containing a full, accurate statement of their affairs. Southwest Virginia Savings Bank, FSB is a federal savings bank regulated by the OTS. The OTS conducts regular examinations of federal savings banks, reviewing such matters as the adequacy of loan loss reserves, quality of loans and investments, management practices, compliance with laws, and other aspects of their operations. In addition to these regular examinations, federal savings banks must furnish the OTS with periodic reports containing a full, accurate statement of their affairs. Supervision, regulation and examination of national banks by the OCC and federal savings banks by the OTS are intended primarily for the protection of depositors rather than shareholders. The various laws and regulations administered by the regulatory agencies affect corporate practices, expansion of business, and provisions of services. Also, monetary and fiscal policies of the United States directly affect bank loans and deposits and thus may affect FNB's and SWVA's earnings. The future impact of these policies and of the continuing regulatory changes in the financial services industry cannot be predicted.

The BHC Act further provides that the Federal Reserve may not approve any acquisition, merger or consolidation that would result in a monopoly or would be in furtherance of any combination or conspiracy to monopolize or attempt to monopolize the business of banking in any part of the United States, or the effect of which may be substantially to lessen competition or to tend to create a monopoly in any section of the country, or that in any other manner would be in restraint of trade, unless it finds the

53

anti-competitive effects of the proposed transaction are clearly outweighed in the public interest by the probable effect of the transaction in meeting the convenience and needs of the community to be served. The Federal Reserve is also required to consider the financial and managerial resources and future prospects of the bank holding companies and banks concerned and the convenience and needs of the community to be served. Consideration of financial resources generally focuses on capital adequacy, which is discussed below.

The BHC Act, as amended by the interstate banking provisions of the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1995, which became effective on September 29, 1996, repealed the prior statutory restrictions on interstate acquisitions of banks by bank holding companies. As a result, FNB and any other bank holding company located in Virginia may now acquire a bank located in any other state, and any bank holding company located outside Virginia may lawfully acquire any Virginia-based bank, regardless of state law to the contrary, in either case subject to some deposit-percentage limitations, aging requirements, and other restrictions. The Act also generally provides that, after June 1, 1998, national and state-chartered banks may branch interstate through acquisitions of banks in other states. By adopting legislation prior to that date, a state had the ability either to "opt in" and accelerate the date after which interstate branching is permissible or "opt out" and prohibit interstate branching altogether. The State of Virginia enacted "opt in" legislation that permitted interstate branching in Virginia on a reciprocal basis through June 1, 1998, and on an unlimited basis thereafter. Accordingly, the banking subsidiaries of FNB and SWVA are currently able to establish and operate branches in other states that have also enacted "opt in" legislation.

Subject to certain amendments made by the recently enacted Gramm-Leach- Bliley Act of 1999 described below, the BHC Act generally prohibits FNB from engaging in activities other than banking or managing or controlling banks, savings banks or other permissible subsidiaries and from acquiring or retaining direct or indirect control of any company engaged in any activities other than those activities determined by the Federal Reserve to be so closely related to banking or managing or controlling banks as to be a proper incident thereto. In determining whether a particular activity is permissible, the Federal Reserve must consider whether the performance of such an activity reasonably can be expected to produce benefits to the public, such as greater convenience, increased competition, or gains in efficiency, that outweigh possible adverse effects, such as undue concentration of resources, decreased or unfair competition, conflicts of interest, or unsound banking practices.

For example, factoring accounts receivable, acquiring or servicing loans, leasing personal property, conducting discount securities brokerage activities, performing some data processing services, acting as agent or broker in selling credit life insurance and other types of insurance in connection with credit transactions, and performing some insurance underwriting activities all have been determined by the Federal Reserve to be permissible activities of bank holding companies. Despite prior approval, the Federal Reserve has the power to order a holding company or its subsidiaries to terminate any activity or to terminate its ownership or control of any subsidiary when it has reasonable cause to believe that continuation of such activity or such ownership or control constitutes a serious risk to the financial safety, soundness, or stability of any bank subsidiary of that bank holding company and is inconsistent with sound banking principles.

54

The Gramm-Leach-Bliley Act of 1999. The Gramm-Leach-Bliley Act of 1999 was enacted on November 12, 1999. The Act draws new lines between the types of activities that are permitted for banking organizations as financial in nature and those that are not permitted because they are commercial in nature. The Act imposes Community Reinvestment Act requirements on financial service organizations that seek to qualify for the expanded powers to engage in broader financial activities and affiliations with financial companies that the Act permits.

The Act creates a new form of financial organization called a financial holding company that may own and control banks, insurance companies and securities firms. A financial holding company is authorized to engage in any activity that is financial in nature or incidental to an activity that is financial in nature or is a complementary activity. These activities include insurance, securities transactions, and traditional banking related activities. The Act establishes a consultative and cooperative procedure between the Federal Reserve Board and the Secretary of the Treasury for the designation of new activities that are financial in nature within the scope of the activities permitted by the Act for a financial holding company. A financial holding company must satisfy special criteria to qualify for the expanded financial powers authorized by the Act. Among those criteria are requirements that all of the depository institutions owned by the financial holding company be rated as well capitalized and well-managed and that all of its insured depository institutions have received a satisfactory rating for Community Reinvestment Act compliance during their last examination. A bank holding company that does not qualify as a financial holding company under the Act is generally limited in the types of activities in which it may engage to those that the Federal Reserve Board has recognized as permissible for bank holding companies prior to the date of enactment of the Act. These activities are described under the "General" heading found above. The Act also authorizes a state bank to have a financial subsidiary that engages as a principal in the same activities that are permitted for a financial subsidiary of a national bank if the state bank meets eligibility criteria and special conditions for maintaining the financial subsidiary.

The Act repeals the prohibition in the Glass-Steagal Act on bank affiliations with companies that are engaged primarily in securities underwriting activities. The Act authorizes a financial holding company to engage in a wide range of securities activities, including underwriting, broker/dealer activities and investment company and investment advisory activities.

Support of Subsidiary Banks. Under Federal Reserve and OTS policy, FNB and SWVA are expected to act as a source of financial strength for, and to commit resources to support their subsidiary banks. This support may be required at times when, absent such policy, FNB may not be inclined to provide it. In addition, any capital loans by a bank holding company to any of its banking subsidiaries are subordinate in right of payment to deposits and to certain other indebtedness of such banks. In the event of a bank holding company's bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a banking subsidiary will be assumed by the bankruptcy trustee and entitled to a priority of payment.

55

Restrictions on Repurchase of Stock. The BHC Act permits a bank holding company such as FNB to purchase shares of its capital stock in an amount up to 10% of its consolidated net worth within a twelve month period without prior approval from the Federal Reserve Board, provided, however, that purchases over 10% must receive prior Federal Reserve Board approval unless the bank holding company qualifies for an exception. The exception provides that a bank holding company is not required to obtain prior Federal Reserve Board approval for its repurchase if the following three conditions are met: (1) both before and immediately after the redemption, the bank holding company is well capitalized;
(2) the bank holding company is well managed; and (3) the bank holding company is not the subject of any unresolved supervisory issues. The Federal Reserve Board construes the first test as requiring the holding company to have a consolidated total risk based capital ratio of 10% or greater, a consolidated tier-1 risk based capital ratio of 6% or more, and the holding company must not be subject to any written regulatory agreement regarding capital. At the present time, FNB would qualify for the exemption described above, and would continue to do so after the proposed merger.

FDIC Regulations

The Federal Deposit Insurance Corporation Act of 1991, which became law in December 1991, requires each federal banking agency to revise its risk-based capital standards to ensure that those standards take adequate account of interest rate risk, concentration of credit risk and the risks of non- traditional activities. In addition, pursuant to FDICIA, each federal banking agency has promulgated regulations, specifying the levels at which a financial institution would be considered "well capitalized", "adequately capitalized", "under capitalized", "significantly under capitalized", or "critically under capitalized", and to take certain mandatory and discretionary supervisory actions based on the capital level of the institution.

Under the regulations implementing the prompt corrective action provisions, an institution shall be deemed to be (1) "well capitalized" if it has total risk-based capital of 10% or more, has a Tier I risk-based capital ratio of 6% or more, has a leverage capital ratio of 5% or more and is not subject to any order or final capital directive to meet and maintain a specific capital level for any capital measure, (2) "adequately capitalized" if it has a total risk-based capital ratio of 8% or more, a Tier I risk-based ratio of 4% or more and a leverage capital ratio of 4% or more (3% under certain circumstances) and does not meet the definition of "well capitalized", (3) "undercapitalized" if it has a total risk-based capital ratio that is less than 8%, a Tier I risk- based capital ratio that is less than 4% or a leverage capital ratio that is less than 4% (3% in certain circumstances), (4) "significantly undercapitalized" if it has a total risk-based capital ratio that is less than 6%, a Tier I risk- based capital ratio that is less than 3% or a leverage capital ratio that is less than 3% and (5) "critically undercapitalized" if it has a ratio of tangible equity to total assets that is equal to or less than 2%. In addition, under certain circumstances, a federal banking agency may reclassify a well capitalized institution as adequately capitalized and may require an adequately capitalized institution or an undercapitalized institution to comply with supervisory actions as if it were in the next lower category (except that the FDIC may not reclassify a significantly undercapitalized institution as critically undercapitalized). Immediately upon becoming undercapitalized, or upon failing to submit or implement a capital plan as required, an institution shall become subject to various regulatory restrictions.

FDICIA also contained the Truth in Savings Act, which requires disclosures to be made in connection with deposit accounts offered to consumers. The regulations have been adopted implementing the provisions of the Truth in Savings Act.

56

In addition, significant provisions of FDICIA required federal banking regulators to draft standards in a number of other important areas to assure bank safety and soundness, including internal controls, information systems and internal audit systems, credit underwriting, asset growth, compensation, loan documentation and interest rate exposure. FDICIA also required the regulators to establish maximum ratios of classified assets to capital, and minimum earnings sufficient to absorb losses without impairing capital. The legislation also contained other provisions which restricted the activities of state- chartered banks, amended various consumer banking laws, limited the ability of "under capitalized" banks to borrow from the Federal Reserve's discount window, and required federal banking regulators to perform annual onsite bank examinations and set standards for real estate lending.

Regulatory Capital Requirements

All depository institutions are required to maintain minimum levels of regulatory capital. The federal bank regulatory agencies have established substantially similar risked based and leverage capital standards for financial institutions that they regulate. These regulatory agencies also may impose capital requirements in excess of these standards on a case-by-case basis for various reasons, including financial condition or actual or anticipated growth. Under the risk-based capital requirements of these regulatory agencies, the bank subsidiaries of FNB and SWVA are each required to maintain a minimum ratio of total capital to risk-weighted assets of at least 8%. At least half of the total capital is required to be "Tier 1 capital," which consists principally of common and some qualifying preferred shareholders' equity, less certain intangibles and other adjustments. The remainder ("Tier 2 capital") consists of a limited amount of subordinated and other qualifying debt (including certain hybrid capital instruments) and a limited amount of the general loan loss allowance. Based upon the applicable regulations, First National Bank and Southwest Virginia Savings Bank, FSB are both "well capitalized."

In addition, the federal regulatory agencies have established a minimum leverage capital ratio (Tier 1 capital to tangible assets). These guidelines provide for a minimum leverage capital ratio of 3% for banks and their respective holding companies that meet certain specified criteria, including that they have the highest regulatory examination rating and are not contemplating significant growth or expansion. All other institutions are expected to maintain a leverage ratio of at least 100 to 200 basis points above that minimum. The guidelines also provide that banking organizations experiencing internal growth or making acquisitions will be expected to maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets.

Deposit Insurance

The deposits of Southwest Virginia Savings Bank, FSB and First National Bank are currently insured to a maximum of $100,000 per depositor, subject to certain aggregation rules. The FDIC has implemented a risk-related assessment system for deposit insurance premiums. All depository institutions have been assigned to one of nine risk assessment classifications based on certain capital and supervisory measures.

Federal Reserve System

The Federal Reserve Board requires all depository institutions to maintain reserves against their transaction accounts (primarily NOW and Super NOW checking accounts) and non-personal time deposits. Because required reserves must be maintained in the form of vault cash or a noninterest-bearing account at a Federal Reserve Bank, the effect of this reserve requirement is to reduce the earning assets of FNB's and SWVA's subsidiary banks.

57

Office of Thrift Supervision

As a federally chartered, SAIF-insured savings association, Southwest Virginia Savings Bank, FSB (the "Savings Bank") is subject to extensive regulation by the Office of Thrift Supervision and the Federal Deposit Insurance Corporation. Lending activities and other investments must comply with various federal statutory and regulatory requirements. The Savings Bank is also subject to certain reserve requirements promulgated by the Federal Reserve.

The OTS, in conjunction with the FDIC, regularly examines the Savings Bank and prepares reports for the consideration of the Savings Bank's Board of Directors on any deficiencies that are found in the Savings Bank's operations. The Savings Bank's relationship with its depositors and borrowers is also regulated to a great extent by federal and state law, especially in such matters as the ownership of savings accounts and the form and content of the Savings Bank's mortgage documents.

The Savings Bank must file reports with the OTS and the FDIC concerning its activities and financial condition, in addition to obtaining regulatory approvals prior to entering into certain transactions such as mergers with or acquisitions of other savings institutions. This regulation and supervision establishes a comprehensive framework of activities in which an institution can engage and is intended primarily for the protection of the SAIF and depositors. The regulatory structure also gives the regulatory authorities extensive discretion in connection with their supervisory and enforcement activities and examination policies, including policies with respect to the classification of assets and the establishment of adequate loan loss reserves for regulatory purposes. Any change in such regulations, whether by the Office of Thrift Supervision, the FDIC, or the U.S. Congress could have a material impact on the Company, the Bank, and their operations.

OTS capital regulations require savings institutions to meet three capital standards: (1) tangible capital equal to 1.5% of total adjusted assets, (2) a leverage ratio (core capital) equal to at least 3% of total adjusted assets, and
(3) a risk-based capital requirement equal to 8.0% of total risk-weighted assets.

OTS regulations also require the Savings Bank to give the OTS 30 days advance notice of any proposed declaration of dividends to SWVA and the OTS has the authority under its supervisory powers to prohibit the payment of dividends to SWVA. In addition, the Savings Bank may not declare or pay a cash dividend on its capital stock if the effect of the dividend would be to reduce the regulatory capital of the Savings Bank below the amount required for the liquidation account established in connection with the Merger.

OTS regulations impose limitations upon all capital distributions by savings institutions, such as cash dividends, payments to repurchase or otherwise acquire its shares, payments to shareholders of another institution in a cash-out merger, and other distributions charged against capital. An institution that exceeds all capital requirements before and after a proposed capital distribution and has not been advised by the OTS that it is in need of more than the normal supervision can, after prior notice to the OTS, make capital distribution during a calendar year equal to its net income to date during the calendar year plus retained net income for the preceding two years. Any additional capital distributions require prior regulatory approval. In the event the Savings Bank's capital fell below its requirements or the OTS notified it that it was in need of more than normal supervision, the Savings Bank's ability to make capital distributions could be further restricted. In addition, the OTS could prohibit a proposed capital distribution by any institution, which would otherwise be permitted by the regulation, if the OTS determines that such distribution would constitute an unsafe or unsound practice.

Savings institutions must meet a QTL test or the definition of a domestic building and loan association under Section 7701 of the Internal Revenue Code. If the Savings Bank maintains an appropriate level of qualified thrift investments (primarily residential mortgages and related investments, including certain mortgage-related securities) and otherwise qualifies as a QTL or a domestic building and loan association, it will continue to enjoy full borrowing privileges from the FHLB of Atlanta. The required percentage of qualified thrift investments is 65% of assets while the Code requires investments of 60% of assets.

FNB Corporation
Notes to Unaudited Pro Forma Combined Condensed Balance Sheet As of September 30, 2000
(Dollars in thousands)

N/A = not applicable
NM = not meaningful

1. Adjust to fair value under generally accepted accounting principles for purchase accounting.

2. Record excess of cost over fair values of assets acquired (goodwill).

3. Debt assumed to be incurred to finance the cash payments to shareholders holding 50% of CNB shares and for 50% of CNB stock options, plus estimated merger costs of $100. Calculated as follows:
CNB shares x 50% x per share merger consideration (926,399 x 50% x $10.60 = $4,910) plus CNB options x 50% x value (consideration of $10.60 minus average exercise price of $8.06 = $2.54): 231,833 x 50% x $2.54 = $294 plus Estimated merger related costs of $100. Total = $4,910 + $294 + $100 = $5,304.

4. Elimination of CNB common stock at par ($4,632) and replace with FNB common stock assumed to be issued in exchange for 50% of CNB shares. Calculated as follows: CNB shares x 50% stock x assumed exchange ratio based on $18 mid-point FNB stock price ($10.60 consideration / $18 = .5889) x $5 par value, or 926,399 x 50% x .5889 x $5 = $1,364 - $4,632 (CNB stock) =
($3,268)

5. Elimination of CNB's additional paid-in-capital ($2,804) and replace with incremental FNB additional paid-in-capital from assumed stock issuance plus estimated fair value of assumed FNB stock options to be issued in exchange for 50% of CNB options. Calculated as follows:

CNB shares x 50% x exchange ratio based on $18 mid-point stock price minus $5 par ($13) plus $354 present value of new FNB stock options, or 926,399 x 50% x .5889 x $13 = $3,546 + $354 - $2,804 = $1,096.

Note: The amounts recorded in common stock and paid-in-capital above in notes 4 and 5 above will vary depending on the exchange ratio; however, the total amount of the two will be the same because the consideration of $10.60 remains constant under any scenario.

6. Elimination of SWVA's and CNB's retained earnings.

7. Elimination of SWVA's and CNB's net unrealized (depreciation) appreciation on securities available for sale. The securities were recorded at fair value in the allocation of the acquisition cost.

8. FNB acquired 20,451 shares of SWVA common stock on August 24, 2000 for $368. This investment would be eliminated on the date of merger.

9. Debt assumed to be incurred to finance the cash payments to shareholders holding 20% of SWVA shares, plus estimated merger costs of $100, less a $47 fair value adjustment related to existing borrowings from FHLB. Calculated as follows:
SWVA shares x 20% x merger consideration (380,575 x 20% x $20.25 = $1,541) plus merger costs of $100, less $47 fair value adjustment $1,541 + $100 - $47 = $1,594.

10. Record deferred tax liability resulting from the fair value adjustments related to SWVA, at effective tax rate of 34%. Because the tax bases of the assets will not change, deferred taxes will be recorded for purchase adjustments except goodwill, in accordance with Statement of Financial Accounting Standards (SFAS) No. 109. No deferred taxes are reflected for the CNB fair value adjustments because they are fully offset by a valuation reserve under SFAS 109.

62

11. Elimination of SWVA common stock at par ($42) and replace with FNB common stock assumed to be issued in exchange for 80% of SWVA shares. Calculated as follows:
SWVA shares x 80% stock x exchange ratio based on $17 mid-point FNB stock price ($20.25 consideration / $17 = 1.191) x $5 par value, or 380,575 x 80% x 1.191 x $5 = $1,813 - $42 = $1,771.

12. Elimination of SWVA's additional paid-in-capital of $2,832 and replace with FNB's incremental additional paid-in-capital from assumed stock issuance plus $342 estimated fair value of assumed FNB stock options to be issued in exchange for 100% of SWVA options. Calculated as follows:
SWVA shares x 80% x exchange ratio based on excess of $17 mid-point FNB stock price over $5 par ($12), or 380,575 x 80% x 1.191 x $12 = $4,351 + 342 -$2,832 = $1,861.

Note: the amounts recorded in common stock and paid-in-capital above in footnotes 11 and 12 will vary depending on the exchange ratio; however, the total amount of the two will be the same because the consideration of $20.25 per share remains constant under any scenario.

13. Elimination of SWVA's unearned ESOP and unearned compensation.

14. Represents the premium over book value of deposits to be acquired that is reflected in net proceeds from acquisition of the two First Union branches. The net proceeds is reflected on a pro forma basis as being used to purchase investment securities available for sale. The terms of the acquisition reflected in the accompanying pro forma financial statements include FNB purchasing premises and equipment, loans, and cash on hand related to the branches. Also reflected is the assumption by FNB of the deposits of the branches. The premium reflected in the transaction (i.e., a reduction of the net proceeds to FNB) is comprised of 8% of the deposits of the Pearisburg branch and 5% of the deposits of the Wytheville branch. The allocation of the net acquisition proceeds among assets (in parentheses) and liabilities assumed is as follows:

  (1,537)  Cash acquired
  (1,683)  Premises and equipment acquired at fair value
 (16,841)  Loans acquired at fair value
   83,471  Deposits assumed at fair value before considering premium
  (4,211)  Goodwill recognized
---------

FNB Corporation
Notes to Unaudited Pro Forma Combined Condensed Statement of Income Year Ending December 31, 1999
(Dollars in thousands)

1. Amortization of CNB's loan fair value adjustment. The amortization periods represent the average remaining expected life of the loans, and they vary from 1.3 years to 7 years depending on the type of loan.

2. Interest on the cost of borrowing amounts to fund cash payments to CNB shareholders in exchange for stock ($388) less amortization of fair value adjustment made relating to CNB's deposits ($462). The assumed annual interest rate on the borrowings is 7.3%. The fair value adjustment is amortized over the expected remaining average life of the related deposits of 1.15 years.

3. Amortization of excess of cost over fair value of assets acquired (goodwill) related to CNB ($217) plus amortization of premises and equipment fair value adjustment ($6). The goodwill is amortized over 20 years using the straight- line method. The premises and equipment adjustments are amortized on a straight-line basis over the 35 year estimated remaining life of the real estate to which it relates.

4. Tax effect of interest on borrowings referred to in Note 2 above ($388 x 34% tax rate = $132).

5. FNB shares to be issued in exchange for 50% of CNB shares outstanding (926,399). Following is the calculation assuming three scenarios regarding FNB's stock price ($18.00, $19.50, and $16.50):

Mid-point: 926,399 x 50% x ($10.60/$18.00) = 272,773 incremental shares Ceiling: 926,399 x 50% x ($10.60/$19.50) = 251,790 incremental shares Floor:
926,399 x 50% x ($10.60/ $16.50) = 297,571 incremental shares

6. FNB shares/stock options to be issued in exchange for 50% of CNB shares and stock options outstanding, assuming all such options were then exercised to the extent the effect would be dilutive for earnings per share. The methodology is:

Basic shares to be issued (Note 5) plus options x 50% x value (consideration of $10.60 less average exercise price of $8.06 = $2.54) divided by FNB share price under all three scenarios.

Mid-point: 272,773 + (231,833 x 50% x $2.54/ $18.00 = 16,357) = 289,130 incremental shares for fully diluted purposes Ceiling: 251,790 + (231,833 x 50% x $2.54/$19.50 = 15,098) = 266,889 incremental shares for fully diluted purposes
Floor: 297,571 + (231,833 x 50% x $2.54/$16.50 = 17,844) = 315,415 incremental shares for fully diluted purposes

7. Amortization of SWVA's loan fair value adjustment. The amortization period of 3.5 years represents the average remaining expected life of the loans.

8. Interest on the cost of borrowing amounts to fund cash payments to SWVA shareholders in exchange for stock ($123) at assumed interest rate of 7.3%. Also includes amortization of fair value adjustment made relating to SWVA's deposits ($530) and FHLB borrowings ($27). The fair value adjustments are amortized over the remaining average life of the related deposits of 13.2 months and the remaining contractual term of the FHLB borrowings of 20.4 months.

65

9. Amortization of excess of cost over fair value of assets acquired (goodwill) related to SWVA ($17) plus amortization of premises and equipment fair value adjustment ($83). The goodwill is amortized over 20 years using the straight- line method. The premises and equipment adjustments are amortized on a straight-line basis over the estimated remaining lives of the particular assets to which they relate, which vary depending on the age and condition of the asset.

10. Tax effect of interest on borrowings referred to in Note 8 above at 34% tax rate. Also includes deferred tax benefit related to reversal of portion of deferred taxes related to fair value adjustments.

11. FNB shares to be issued in exchange for 80% of SWVA shares outstanding, net of SWVA shares already owned by FNB (380,575). Following is the calculation assuming three scenarios regarding FNB's stock price ($17.00, $18.70, and $15.30):

Mid-point: 380,575 x 80% x ($20.25/$17.00) = 362,666 incremental shares Ceiling: 380,575 x 80% x ($20.25/$18.70) = 329,696 incremental shares Floor:
380,575 x 80% x ($20.25/$15.30) = 402,962 incremental shares

12. FNB shares/stock options to be issued in exchange for 80% of SWVA shares and 100% of SWVA stock options outstanding, assuming all such options were then exercised to the extent the effect would be dilutive for earnings per share. The methodology is:

Basic shares to be issued (Note 11) plus options x value (consideration of $20.25 less average exercise price of $16.80 = $3.45) divided by FNB share price under all three scenarios.

Mid-point: 362,666 + (64,049 x $3.45/$17.00 = 12,998) = 375,664 incremental shares for fully diluted purposes
Ceiling: 329,696 + (64,049 x $3.45/$18.70 = 11,817) = 341,513 incremental shares for fully diluted purposes
Floor: 402,962 + (64,049 x $3.45/$15.30 = 14,442) = 417,404 incremental shares for fully diluted purposes

13. Interest income effect ($364) of deposit premium reflected in acquisition of First Union branches. The premium has the effect of reducing the amount available to invest in securities, and as such the rate used to calculate the effect is the average yield on FNB's securities portfolio of 6.85%.

This item also includes amortization of the loan fair value adjustment ($50) related to the First Union purchase over the average remaining expected life of the loans of 1.9 years.

14. Amortization of First Union deposit fair value adjustment over the expected remaining average life of each of the related categories of deposits. The weighted average life is 1.6 years.

15. Amortization of excess of cost over fair value of assets acquired (goodwill) related to First Union. The goodwill is amortized over 10 years using the straight-line method. This term represents management's estimate of the estimated average remaining life of the customer deposit base being acquired in accordance with SFAS No. 72.

16. Income tax benefit at a 34% tax rate is reflected on the net pre-tax adjustments. The tax benefit of goodwill amortization is included because the goodwill resulting from the First Union acquisition is expected to be deductible under the provisions of the Internal Revenue Code.

17. Historical interest income and expense amounts for the First Union branches were not available. Amounts of interest income and expense were estimated based on the amounts of loans being purchased and deposits being assumed, respectively, using historical average yield percentages for FNB modified to the extent necessary to reflect characteristics of the particular loan portfolios and deposits being purchased/assumed. Historical noninterest income and expenses for the branches were available and were used in these proformas. Income taxes were recorded using a 34% rate.

FNB Corporation
Notes to Unaudited Pro Forma Combined Condensed Statement of Income Nine Months Ending September 30, 2000
(Dollars in thousands)

1. Amortization of CNB's loan fair value adjustments. The amortization periods represent the average remaining expected life of the loans, and they vary from 1.3 years to 7 years depending on the type of loan.

2. Interest on the cost of borrowing amounts to fund cash payments to CNB shareholders in exchange for stock ($291) less the amortization of the remaining portion of the fair value adjustment made relating to CNB's deposits ($70). The assumed annual interest rate on the borrowings is 7.3%.

3. Amortization of excess of cost over fair value of assets acquired (goodwill) related to CNB ($163) plus amortization of premises and equipment fair value adjustment ($4). The goodwill is amortized over 20 years using the straight- line method. The premises and equipment adjustments are amortized on a straight-line basis over the 35 year estimated remaining life of the real estate to which it relates.

4. Tax effect of interest on borrowings referred to in footnote 2 above ($291 x 34% tax rate = $99).

5. FNB shares to be issued in exchange for 50% of CNB shares outstanding (926,399). Following is the calculation assuming three scenarios regarding FNB's stock price ($18.00, $19.50, and $16.50):

Mid-point: 926,399 x 50% x ($10.60/$18.00) = 272,773 incremental shares Ceiling: 926,399 x 50% x ($10.60/$19.50) = 251,790 incremental shares Floor:
926,399 x 50% x ($10.60/ $16.50) = 297,571 incremental shares

6. FNB shares/stock options to be issued in exchange for 50% of CNB shares and stock options outstanding, assuming all such options were then exercised to the extent the effect would be dilutive for earnings per share. The methodology is:

Basic shares to be issued (Note 5) plus options x 50% x value (consideration of $10.60 less average exercise price of $8.06 = $2.54) divided by FNB share price under all three scenarios.

Mid-point: 272,773 + (231,833 x 50% x $2.54/ $18.00 = 16,357) = 289,130 incremental shares for fully diluted purposes Ceiling: 251,790 + (231,833 x 50% x $2.54/$19.50 = 15,098) = 266,889 incremental shares for fully diluted purposes Floor: 297,571 + (231,833 x 50% x $2.54/$16.50 = 17,844) = 315,415 incremental shares for fully diluted purposes

7. Amortization of SWVA's loan fair value adjustment. The amortization period of 3.5 years represents the average remaining expected life of the loans.

68

8. Interest on the cost of borrowing amounts to fund cash payments to SWVA shareholders in exchange for stock ($92) at assumed interest rate of 7.3%. Also includes amortization of fair value adjustment made relating to FHLB borrowings ($21) and the remaining portion of the fair value adjustment for SWVA's deposits ($53). The fair value adjustments are amortized over the remaining average life of the related deposits of 13.2 months and the remaining contractual term of the FHLB borrowings of 20.4 months.

9. Amortization of excess of cost over fair value of assets acquired (goodwill) related to SWVA ($12) plus amortization of premises and equipment fair value adjustment ($63). The goodwill is amortized over 20 years using the straight- line method. The premises and equipment adjustments are amortized on a straight-line basis over the estimated remaining lives of the particular assets to which they relate, which vary depending on the age and condition of the asset. Also reflected here is a reduction of $150 of non-recurring merger related expenses. See Note 17 for details.

10. Tax effect of interest on borrowings referred to in Note 8 above at 34% tax rate. Also includes deferred tax benefit related to reversal of portion of deferred taxes related to fair value adjustments and the tax effect of the excluded merger related expenses ($98).

11. FNB shares to be issued in exchange for 80% of SWVA shares outstanding, net of SWVA shares already owned by FNB (380,575). Following is the calculation assuming three scenarios regarding FNB's stock price ($17.00, $18.70, and $15.30):

Mid-point: 380,575 x 80% x ($20.25/$17.00) = 362,666 incremental shares Ceiling: 380,575 x 80% x ($20.25/$18.70) = 329,696 incremental shares Floor: 380,575 x 80% x ($20.25/$15.30) = 402,962 incremental shares

12. FNB shares/stock options to be issued in exchange for 80% of SWVA shares and 100% of SWVA stock options outstanding, assuming all such options were then exercised to the extent the effect would be dilutive for earnings per share. The methodology is:

Basic shares to be issued (Note 11) plus options x value (consideration of $20.25 less average exercise price of $16.80 = $3.45) divided by FNB share price under all three scenarios.

Mid-point: 362,666 + (64,049 x $3.45/$17.00 = 12,998) = 375,664 incremental shares for fully diluted purposes Ceiling: 329,696 + (64,049 x $3.45/$18.70 = 11,817) = 341,513 incremental shares for fully diluted purposes Floor: 402,962 + (64,049 x $3.45/$15.30 = 14,442) = 417,404 incremental shares for fully diluted purposes

13. Interest income effect ($273) of deposit premium reflected in acquisition of First Union branches. The premium has the effect of reducing the amount available to invest in securities, and as such the rate used to calculate the effect is the average yield on FNB's securities portfolio of 6.85%.

This item also includes amortization of the loan fair value adjustment ($38) related to the First Union purchase over the average remaining expected life of the loans of 1.9 years.

14. Amortization of First Union deposit fair value adjustment over the expected remaining average life of each of the related categories of deposits. The weighted average life is 1.6 years.

69

15. Amortization of excess of cost over fair value of assets acquired (goodwill) related to First Union. The goodwill is amortized over 10 years using the straight-line method. This term represents management's estimate of the estimated average remaining life of the customer deposit base being acquired in accordance with SFAS No. 72.

16. Income tax benefit at a 34% tax rate is reflected on the net pre-tax adjustments. The tax benefit of goodwill amortization is included because the goodwill resulting from the First Union acquisition is expected to be deductible under the provisions of the Internal Revenue Code.

17. Note 9 refers to an adjustment to SWVA historical amounts for the nine months ended September 30, 2000 to remove $150 of nonrecurring costs ($98 after tax) directly related to the merger. These costs are comprised of fees paid to attorneys and financial advisors for services directly related to the proposed merger with FNB, including evaluation of the legal and financial details of the merger, the fairness opinion, and other related matters. CNB had not incurred significant merger related costs as of September 30, 2000. Most merger related costs for FNB had been capitalized under generally accepted accounting principles.

18. Historical interest income and expense amounts for the First Union branches were not available. Amounts of interest income and expense were estimated based on the amounts of loans being purchased and deposits being assumed, respectively, using historical average yield percentages for FNB modified to the extent necessary to reflect characteristics of the particular loan portfolios and deposits being purchased/assumed. Historical noninterest income and expenses for the branches were available and were used in these proformas. Income taxes were recorded using a 34% rate.

Comparative Per Share Data

The following table sets forth certain historical, pro forma and pro forma equivalent per share financial information for the common stock of FNB and SWVA. The pro forma and pro forma equivalent per share information gives effect to the merger as if the merger had been effective on the dates presented in the case of the book value data, and as if the merger had become effective January 1, 1999, in the case of the net income and dividends declared data presented. The pro forma data in the tables assumes that the merger is accounted for using the purchase method of accounting. See "Accounting Treatment." The information presented herein is based on, and is qualified in its entirety by, the historical financial statements, including the notes thereto, of FNB and SWVA incorporated by reference herein, and should be read in conjunction therewith. See "Available Information," and "Incorporation of Certain Information by Reference." The pro forma and equivalent pro forma per share data in the following tables are presented for comparative purposes only and are not necessarily indicative of what the combined financial position or results of operations would have been had the merger been consummated during the periods or as of the date for which such pro forma tables are presented.

The ultimate exchange ratio for the merger will be based upon the average per share market price of FNB common stock over a 30 day trading period shortly before the closing of the merger. The tables below reflect three potential per share market prices of FNB common stock: $17, $18.70, and $15.30.

(1) FNB uses a calendar year-end for financial reporting purposes, while SWVA uses a June 30 fiscal year-end. In order to enhance the comparability of this per share data, the historical SWVA financial information was converted to a calendar year basis.

(2) Per equivalent SWVA share amounts are calculated by multiplying the pro forma combined amounts by the Exchange Ratio of 1.191 for the $17 per FNB share market price scenario, an Exchange Ratio of 1.083 for the $18.70 per FNB share market price scenario, and an Exchange Ratio of 1.324 for the $15.30 per FNB share market price scenario.

(3) The pro forma net income per share amounts are calculated by totaling the historical net income of FNB and SWVA (as adjusted per Note 1 above), adjusting the result to give effect to the merger as though it had occurred on January 1, 1999, and dividing it by pro forma average basic and fully diluted shares. To arrive at pro forma shares, FNB's historical average shares outstanding were added to the incremental shares that would be issued, assuming the Exchange Ratio applicable to the particular scenario, in exchange for 80% of the historical SWVA shares outstanding. The pro forma net income per share amounts do not take into consideration any operating efficiencies that may be realized as a result of the merger.

74

(4) Pro forma cash dividends represents the FNB historical amounts.

(5) Pro forma book value per share amounts are calculated by dividing pro forma combined stockholders' equity by pro forma common shares outstanding at the end of the period. Pro forma stockholders' equity gives effect to the merger as though it had occurred on September 30, 2000. To arrive at pro forma shares outstanding, FNB's historical shares outstanding at September 30, 2000 were added to the incremental shares that would be issued assuming the merger occurred at September 30, 2000, assuming the Exchange Ratio applicable to the particular scenario, in exchange for 80% of the historical SWVA shares outstanding at that date. Pro forma shares outstanding used for book value calculations in the above table do not include unearned shares held by Employee Stock Ownership Plans sponsored by FNB and SWVA.

            FNB Corporation

Exhibit B - Exchange Agent Agreement

Exhibit C - Affiliate Agreement


AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (the "Agreement") is made and entered into as of August 7, 2000 by and between FNB Corporation, a Virginia corporation with its principal office located in Christiansburg, Virginia ("FNB"), and SWVA Bancshares, Inc., a Virginia corporation with its principal office located in Roanoke, Virginia ("SWVA").

WITNESSETH:

WHEREAS, FNB and SWVA (together, the "Companies") desire to affiliate, so that First National Bank ("First National") and Southwest Virginia Savings Bank, FSB ("SVSB") (together, the "Banks") will be under the common control of FNB; and

WHEREAS, FNB and SWVA have agreed to the affiliation of their two companies through a merger under Virginia law, as a result of which SWVA would merge with and into FNB and the shareholders of SWVA would become shareholders of FNB, all as more specifically provided in this Agreement and the Plan of Merger in the form attached hereto as Exhibit A (the "Plan"); and

WHEREAS, the Boards of Directors of the Companies each believe it is in the best interests of their respective corporations and their shareholders to affiliate as provided herein and that the respective shareholder values of FNB and SWVA can be maximized over time through this affiliation; and

WHEREAS, the Boards of Directors of the Companies each believe that the transaction contemplated in this Agreement is in the best interests of the communities they serve and of their respective employees; and

WHEREAS, the Boards of Directors of the Companies each believe that after the affiliation the holding company structure should provide management and technical assistance and support for recruitment, training and retention of skilled officers and employees to the Banks in order to enable the combined organization to operate more efficiently; and

WHEREAS, the respective Boards of Directors of the Companies have resolved that the transactions described herein are in the best interests of the parties and their respective shareholders and have authorized and approved the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:


ARTICLE 1
The Merger and Related Matters

1.1 Definitions. Any term defined anywhere in this Agreement shall have the meaning ascribed to it for all purposes of this Agreement (unless expressly noted to the contrary). In addition:

(a) the term "knowledge" when used with respect to a party shall mean the knowledge of any "Executive Officer" of such party, as such term is defined in Regulation O, (12 C.F.R. 215);

(b) the term "Material Adverse Effect", when applied to a party, shall mean an event, occurrence or circumstance (including without limitation
(i) the making of any provisions for possible loan and lease losses, write-downs or other real estate and taxes and (ii) any breach of a representation or warranty by such party) which (a) has or is reasonably likely to have a material adverse effect on the financial position, results of operations or business of the party and its subsidiaries, taken as a whole, or (b) would materially impair the party's ability to perform its obligations under this Agreement or the consummation of the Merger and the other transactions contemplated by this Agreement; provided, however, that solely for purposes of measuring whether an event, occurrence or circumstance has a material adverse effect on such party's results of operations, the term "results of operations" shall mean net interest income plus non-interest income (less securities gains) less gross expenses (excluding provisions for possible loan and lease losses, write-downs of other real estate and taxes); and provided further, that material adverse effect and material impairment shall not be deemed to include the impact of (i) changes in banking and similar laws of general applicability or interpretations thereof by courts or governmental authorities, (ii) changes in generally accepted accounting principles or regulatory accounting requirements applicable to banks and bank holding companies generally, and (iii) the Merger and related expenses associated with the transactions contemplated by this Agreement on the operating performance of the parties to this Agreement; and

(c) the term "Previously Disclosed" by a party shall mean information set forth in a written disclosure letter that is delivered by that party to the other party prior to or contemporaneously with the execution of this Agreement and specifically designated as information "Previously Disclosed" pursuant to this Agreement.

1.2 The Merger. Subject to the terms and conditions of this Agreement, at the Effective Date as defined in Section 1.5 hereof, SWVA will be merged with and into FNB (the "Merger"). At the Effective Date, the Merger shall have the effect as provided in Section 13.1-721 of the Virginia Stock Corporation Act.

1.3 Name and Continuing Operations. The respective names and banking offices of the Banks will not change as a result of the Merger. After the Effective Date, FNB shall continue to be headquartered in Christiansburg, Virginia.

2

1.4 Management of FNB and the Banks. The directors, officers and employees of the Banks will not change as a result of the Merger except that Julian D. Hardy, Jr. shall be appointed to the Board of SVSB. On the Effective Date, the number of Directors of FNB shall be increased by two members by adding one member in Class I whose terms expire at the 2003 annual meeting of shareholders and by adding one member in Class III whose terms expire at the 2002 annual meeting of shareholders. B. L. Rakes shall be appointed to fill the vacancy created in Class I and Courtney Hoge shall be appointed to fill the vacancy created in Class III. At the next annual meeting of shareholders of FNB, management of FNB will recommend to shareholders that those gentlemen be elected as a member of Class I and Class III, respectively. In addition, on the Effective Date, FNB agrees to assume the employment agreements between SWVA and D. W. Shilling and Barbara Weddle, and as of the Effective Time, FNB shall enter into an Addendum to the employment agreement for D. W. Shilling and Barbara Weddle, as attached hereto as Exhibit 1.4. In addition, as of the Effective Date, FNB shall enter into an agreement with B. L. Rakes in which FNB agrees to pay Mr. Rakes $17,000 in consideration for his agreement not to compete with FNB and its affiliates for a period of one year.

1.5 The Closing and Effective Date. The closing of the transactions contemplated by this Agreement and the Plan of Merger shall take place at the offices of FNB in Christiansburg, Virginia or at such other place as may be mutually agreed upon by the parties. The Merger shall become effective on the date shown on the Certificate of Merger issued by the State Corporation Commission of Virginia effecting the Merger (the "Effective Date"). Unless otherwise agreed upon in writing by the chief executive officers of FNB and SWVA, subject to the conditions to the obligations of the parties to effect the Merger as set forth in Article 6, the parties shall use their best efforts to cause the Effective Date to occur on the first day of the month following the month in which the conditions set forth in Sections 7.1(a) and 7.1(b) are satisfied. All documents required by the terms of this Agreement to be delivered at or prior to consummation of the Merger will be exchanged by the parties at the closing of the Merger (the "Merger Closing"), which shall be held on or before the Effective Date. FNB and SWVA shall execute and deliver to the Virginia State Corporation Commission Articles of Merger containing a Plan of Merger in substantially the form of Exhibit A hereto.

ARTICLE 2
Basis and Manner of Conversion

2.1 Conversion of SWVA Stock. At the Effective Date, by virtue of the Merger, each share of the common stock, par value $0.10 per share, of SWVA ("SWVA Common Stock") issued and outstanding immediately prior to the Effective Date will be converted into either cash (the "Cash Consideration") or shares of common stock, par value $5.00 per share, of FNB ("FNB Common Stock"), the "Stock Consideration," which Stock Consideration together with the Cash Consideration (the "Merger Consideration"), in each case as the holder thereof shall have elected or be deemed to have elected in accordance with Section 2.3.

3

In the case that the Market Value of FNB Common Stock (as defined later in this Section 2.1) is equal to or greater than $15.30 per share and equal to or less than $18.70 per share, the Cash Consideration will be $20.25 per share and the Stock Consideration will equal shares of FNB Common Stock with a Market Value of $20.25. In the case that the Market Value of FNB Common Stock is greater than $18.70 and less than or equal to $20.00, the Stock Consideration will equal 1.083 shares of FNB Common Stock for each outstanding share of SWVA Common Stock, and the Cash Consideration will be $20.25. In the case that the Market Value of FNB Common Stock is less than $15.30 and equal to or greater than $14.00, the Stock Consideration will equal 1.324 shares of FNB Common Stock for each outstanding share of SWVA Common Stock, and the Cash Consideration will be $20.25.

The Market Value of FNB Common Stock will be the average of the last reported sales prices per share of FNB Common Stock as reported on the NASDAQ Exchange Composite Transactions Tape (as reported in The Wall Street Journal, or, if not reported thereby, another authoritative source as chosen by FNB) for the thirty consecutive full trading days on such exchange (even if FNB Common Stock does not trade in each such day) ending at the close of trading on the tenth calendar day before the Effective Date (the "Market Value" and the "Measurement Period"). The ratio of shares of FNB's Common Stock that will be exchanged for each outstanding share of SWVA Common Stock shall be referred to herein as the "Exchange Ratio" and shall be rounded to the nearest thousandth decimal point.

2.2 Allocation. Notwithstanding anything in this Agreement to the contrary, the aggregate amount of cash to be issued to shareholders of SWVA in the Merger shall be equal to $1,785,742 (the "Cash Amount"); provided that the Cash Amount may be changed by FNB to accommodate the exercise by FNB of its option to change the Cash Number and the Stock Number pursuant to the last sentence of this Section 2.2. As used in this Agreement, the Cash Number shall mean the aggregate number of shares of SWVA Common Stock to be converted into the right to receive the Cash Consideration in the Merger, which shall be equal to the Cash Amount divided by $20.25. The number of shares of SWVA Common Stock to be converted into the right to receive Stock Consideration (the "Stock Number") will be equal to (i) the number of shares of SWVA Common Stock issued and outstanding immediately prior to the Effective Date of the Merger less (ii) the sum of (A) the Cash Number and (B) the aggregate number of shares of SWVA Common Stock to be exchanged for cash pursuant to Section 3.3. FNB shall have the option to change the Cash Number and the Stock Number to more closely follow the actual elections of SWVA shareholders pursuant to this Article 2, so long as such modification to the Cash Number and the Stock Number does not prevent the condition set forth in Section 7.1(d) from being satisfied.

2.3 Election. Subject to allocation in accordance with the provisions of this Article, each record holder of shares of SWVA Common Stock issued and outstanding immediately prior to the Election Deadline (as defined in Section 3.1(i)) will be entitled, in accordance with Section 3.1, (i) to elect to receive in respect of each such share held in such manner (A) Cash Consideration (a "Cash Election") or (B) Stock Consideration (a "Stock Election") thus, making an election for all Cash Consideration, all Stock Consideration, or a mixture

4

thereof or (ii) to indicate that such record holder has no preference as to the receipt of Cash Consideration or Stock Consideration for all such shares held by such holder (a "Non-Election"). Shares of SWVA Common Stock in respect of which a Non-Election is made or as to which no election is made (collectively, "Non- Election Shares") shall be deemed by FNB to be shares in respect of which Cash Elections or Stock Elections have been made, as FNB shall determine. Holders of record of shares of SWVA Common Stock who hold such shares as nominees, trustees or in other representative capacities (a "Representative") may submit multiple Forms of Election (as hereinafter defined), provided that each such Form of Election covers all the shares of SWVA Common Stock held by that Representative for a particular beneficial owner.

2.4 Allocation of Cash Election Shares. In the event that the aggregate number of shares in respect of which Cash Elections have been made (the "Cash Election Shares") exceeds the Cash Number, all shares of SWVA Common Stock in respect of which Stock Elections have been made (the "Stock Election Shares") and all Non-Election Shares will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with
Section 3.3), and Cash Election Shares will be converted into the right to receive Cash Consideration or Stock Consideration in the following manner:

(i) the number of Cash Election Shares covered by each Form of Election (as defined in Section 3.1(i)) to be converted into Cash Consideration will be determined by multiplying the number of Cash Election Shares covered by such Form of Election by a fraction, (A) the numerator of which is the Cash Number and (B) the denominator of which is the aggregate number of Cash Election Shares rounded down to the nearest whole number; and

(ii) all Cash Election Shares not converted into Cash Consideration in accordance with Section 2.4(i) will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3).

Provided, however, that cash in lieu of fractional interests and cash to be paid in connection with rights of dissenting shareholders, as provided in Sections 3.3 and 3.5, respectively, shall not be included in any determination of whether this Section 2.4 shall be given effect.

2.5 Allocation of Stock Election Shares. In the event that the aggregate number of Stock Election Shares exceeds the Stock Number, all Cash Election Shares and all Non-Election Shares (together, the " Cash Shares") will be converted into the right to receive Cash Consideration, and all Stock Election Shares will be converted into the right to receive Cash Consideration or Stock Consideration in the following manner:

(i) the number of Stock Election Shares covered by each Form of Election to be converted into Cash Consideration will be determined

5

by multiplying the number of Stock Election Shares covered by such Form of Election by a fraction, (A) the numerator of which is the Cash Number less the number of Cash Shares and (B) the denominator of which is the aggregate number of Stock Election Shares, rounded down to the nearest whole number; and

(ii) all Stock Election Shares not converted into Cash Consideration in accordance with Section 2.5(i) will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3).

2.6 No Allocation. In the event that neither Section 2.4 nor Section 2.5 is applicable, all Cash Election Shares will be converted into the right to receive Cash Consideration, all Stock Election Shares will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3) and Non-Election Shares will be converted into the right to receive Cash Consideration or Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3) as the Exchange Agent shall determine.

2.7 Computations. The Exchange Agent (as defined in Section 3.1(i)) will make all computations to give effect to this Article 2.

2.8 Cancellation of Shares. As of the Effective Date of the Merger, all such shares of SWVA Common Stock will no longer be outstanding and automatically be cancelled and retired and will cease to exist and each holder of a certificate formerly representing any such shares of SWVA Common Stock (a "SWVA Certificate") will cease to have any rights with respect thereto, except the right to receive Merger Consideration and any additional cash in lieu of fractional shares of FNB Common Stock to be issued or paid in consideration therefor upon surrender of such SWVA Certificate in accordance with Article 3, without interest, subject to rights of dissenting shareholders as provided under
Section 3.5.

ARTICLE 3
Manner of Exchange

3.1 Exchange Procedures.

(i) Not more than 45 days nor fewer than 30 days prior to the Effective Date, First National, as the exchange agent ("Exchange Agent"), will mail a form of election (the "Form of Election") to each shareholder of record of SWVA as of a record date as close as practicable to the date of mailing and mutually agreed to by SWVA and FNB. The Exchange Agent shall enter into a written agreement with FNB and SWVA detailing its duties and responsibilities and shall furnish evidence of liability insurance for such activities in a form substantially similar to Exhibit B. In addition, the Exchange Agent will use its best efforts to make the Form of Election available to the persons who become shareholders of SWVA during the period between such record

6

date and the Effective Date. Any election to receive Merger Consideration will have been properly made only if the Exchange Agent shall have received on the fifth business day immediately preceding the Effective Date (the "Election Deadline"), a Form of Election properly completed and accompanied by a SWVA Certificate ("Certificate(s)") for the shares to which such Form of Election relates, acceptable for transfer on the books of SWVA (or an appropriate guarantee of delivery), as set forth in such Form of Election. An election may be revoked only by written notice received by the Exchange Agent prior to 5:00 p.m. on the Election Deadline. If an election is so revoked, the Certificate(s) (or guarantee of delivery, as appropriate) to which such election relates will be promptly returned to the person submitting the same to the Exchange Agent.

(ii) As soon as reasonably practicable after the Effective Date, the Exchange Agent will mail to each holder of record of a Certificate, whose shares of SWVA Common Stock were converted into the right to receive Merger Consideration and those who failed to return a properly completed Form of Election, (i) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon delivery of the Certificates to the Exchange Agent and will be in such form and have such other provisions as the Exchange Agent may specify consistent with this Agreement) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration.

(iii) With respect to properly made elections in accordance with Section 3.1(i), and upon surrender in accordance with
Section 3.1(ii) of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate will be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive pursuant to the provisions of Article 2, and the Certificate so surrendered will forthwith be canceled. In the event of a transfer of ownership of Shares that are not registered in the transfer records of SWVA, as the case may be, payment may be issued to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate is properly endorsed or otherwise in proper form for transfer and the person requesting such issuance pays any transfer or other taxes required by reason of such payment to a person other than the registered holder of such Certificate or establishes to the satisfaction of FNB that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 3.1, each Certificate will be deemed at any time after the Effective Date to represent only the right to receive upon such surrender the Merger Consideration that the holder thereof has the right to receive in respect of such Certificate

7

pursuant to the provisions of Article 2. No interest will be paid or will accrue on any cash payable to holders of Certificates pursuant to the provisions of Article 2.

3.2 Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to the shares of SWVA Common Stock with a record date after the Effective Date shall be paid to the holder of any unsurrendered Certificate with respect to the shares of SWVA Common Stock represented thereby, and no cash payment in lieu of any fractional shares shall be paid to any such holder pursuant to Section 3.3. Subject to the effect of unclaimed property, escheat and other applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the Certificate representing whole shares of SWVA Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of SWVA Common Stock to which such holder is entitled pursuant to Section 3.3, and (ii) the amount of dividends or other distributions, if any, with a record date after the Effective Date.

3.3 No Fractional Securities. No FNB Certificates or scrip representing fractional shares of FNB Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional shares shall not entitle the owner thereof to vote or to any other rights of a holder of FNB Common Stock. A holder of Shares converted in the Merger who would otherwise have been entitled to a fractional share of FNB Common Stock shall be entitled to receive a cash payment (without interest) in lieu of such fractional share in an amount determined by multiplying (i) the fractional share interest to which such holder would otherwise be entitled by (ii) the Market Value of FNB Common Stock.

3.4 Certain Adjustments. If, after the date hereof and on or prior to the Closing Date, the outstanding shares of SWVA Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination or exchange of shares, or any dividend payable in stock or other securities is declared thereon with a record date within such period, or any similar event shall occur, the Merger Consideration will be adjusted accordingly to provide to the holders of SWVA Common Stock, respectively, the same economic effect as contemplated by this Agreement prior to such reclassification, recapitalization, split-up, combination, exchange or dividend or similar event.

3.5 Rights of Dissenting Shareholders. Shareholders of SWVA who object to the Merger will be entitled to the rights and remedies set forth in sections 13.1-729 through 13.1-741 of the Virginia Stock Corporation Act.

(2) Neither the execution and delivery of the Agreement, the consummation of the transactions contemplated therein, nor the compliance by SWVA with any of the provisions thereof will (i) conflict with or result in a breach of any provision of the Articles of Incorporation or Bylaws of SWVA, (ii) except as Previously Disclosed, constitute or result in the breach of any term, condition or provision of, or constitute default under, or give rise to any right of termination, cancellation or acceleration with respect to, or result in the creation of any lien, charge or encumbrance upon, any property or assets of the SWVA Companies pursuant to (A) any note, bond, mortgage, indenture, or (B) any material license, agreement, lease or other instrument or obligation, to which any of the SWVA Companies is a party or by which any of them or any of their properties or assets may be bound, or (iii) subject to the receipt of the requisite approvals referred to in Section 4.7, violate any order, writ, injunction, decree, statute, rule or regulation applicable to any of the SWVA Companies or any of their properties or assets.

At June 30, 1999, and at any subsequent date reflected in such Financial Statements, none of the SWVA Companies had any obligation or liability (contingent or otherwise) of any nature which were not reflected in the SWVA Financial Statements, except for those which in the aggregate are immaterial or have been Previously Disclosed.

(g) Legal Proceedings; Compliance with Laws. Except as Previously Disclosed, there are no actions, suits or proceedings instituted or pending or, to the best knowledge of SWVA, threatened or probable of assertion against any of the SWVA Companies, or against any property, asset, interest or right of any of them, that are reasonably expected to have, either individually or in the aggregate, a material adverse effect on the financial condition of SWVA on a consolidated basis or that are reasonably expected to threaten or impede the consummation of the transactions contemplated by this Agreement.

Except as Previously Disclosed, as of the date of this Agreement, none of the SWVA Companies nor any of their properties is a party to or is subject to any order, decree, agreement, memorandum of understanding or similar arrangement with, or a

(1) Except as Previously Disclosed, neither FNB nor any FNB subsidiary is a party to, or is bound by, (i) any material agreement, arrangement or commitment, (ii) any agreement, indenture or other instrument relating to the borrowing of money by FNB or any FNB Subsidiary or the guarantee by FNB or any FNB Subsidiary of any such obligation, (iii) any agreement, arrangement or commitment relating to the employment of a consultant or the employment, election, retention in office or severance of any present or former director or officer, (iv) any agreement to make loans or for the provision, purchase or sale of goods, services or property between FNB or any FNB Subsidiary and any director or officer of FNB or any FNB Subsidiary, or any member of the immediate family or affiliate of any of the foregoing, or (v) any agreement between FNB or any FNB Subsidiary and any 5% or more shareholder of FNB; in each case other than agreements entered into in the ordinary course of the banking business of FNB or a FNB Subsidiary consistent with past practice.

(2) Neither FNB or any FNB Subsidiary, nor to the knowledge of FNB, the other party thereto, is in default under any material agreement, commitment, arrangement, lease, insurance policy or other instrument whether entered into in the ordinary course of business or otherwise, nor has there occurred any event

23

that, with the lapse of time or giving of notice or both, would constitute such a default, other than defaults of loan agreements by borrowers from FNB or a FNB Subsidiary in the ordinary course of its business.

(p) Insurance. A complete list of all policies or binders of fire, liability, product liability, workmen's compensation, vehicular and other insurance held by or on behalf of the FNB Companies has previously been furnished to SWVA and all such policies or binders are valid and enforceable in accordance with their terms, are in full force and effect, and insure against risks and liabilities to the extent and in the manner customary for the industry and are deemed appropriate and sufficient by FNB. The FNB Companies are not in default with respect to any provision contained in any such policy or binder and have not failed to give any notice or present any claim under any such policy or binder in due and timely fashion. None of the FNB Companies has received notice of cancellation or non-renewal of any such policy or binder. None of the FNB Companies has knowledge of any inaccuracy in any application for such policies or binders, any failure to pay premiums when due or any similar state of facts or the occurrence of any event that is reasonably likely to form the basis for any material claim against it not fully covered (except to the extent of any applicable deductible) by the policies or binders referred to above. None of the FNB Companies has received notice from any of its insurance carriers that any insurance premiums will be increased materially in the future or that any such insurance coverage will not be available in the future on substantially the same terms as now in effect.

(q) Loans, OREO, and Allowance for Loan Losses. (1) Except as Previously Disclosed, and except for matters which individually or in the aggregate, do not materially adversely affect the Merger or the financial condition of FNB, to FNB's best knowledge each loan reflected as an asset in the FNB Financial Statements or the financial statements of any FNB Subsidiary (i) is evidenced by notes, agreements, or other evidences of indebtedness which are true, genuine and what they purport to be, (ii) to the extent secured, has been secured by valid liens and security interests which have been perfected, and
(iii) is the legal, valid and binding obligation of the obligor named therein, enforceable in accordance with its terms, subject to bankruptcy, insolvency, and other laws of general applicability relating to or affecting creditors' rights and to general equity principles. All loans and extensions of credit which are subject to regulation of the Federal Reserve which have been made by FNB and the FNB Subsidiaries comply therewith.

(2) The classification on the books and records of FNB and each FNB Subsidiary of loans and/or non-performing assets as nonaccrual, troubled debt restructuring, OREO or other similar classification, complies in all material respects with generally accepted accounting principles and applicable regulatory accounting principles.

(3) Except for liens, security interests, claims, charges, or such other encumbrances as have been appropriately reserved for in the FNB Financial Statements or are not material, title to the OREO is good and marketable, and there are no adverse claims or encumbrances on the OREO. All title, hazard and

24

other insurance claims and mortgage guaranty claims with respect to the OREO have been timely filed and neither FNB nor any FNB Subsidiary has been received any notice of denial of any such claim.

(4) FNB and each FNB Subsidiary are in possession of all of the OREO or, if any of the OREO remains occupied by the mortgagor, eviction or summary proceedings have been commenced or rental arrangements providing for market rental rates have been agreed upon and FNB and/or each FNB Subsidiary are diligently pursuing such eviction of summary proceedings or such rental arrangements. Except as Previously Disclosed, no legal proceeding or quasi- legal proceeding is pending or, to the knowledge of FNB and each FNB Subsidiary, threatened concerning any OREO or any servicing activity or omission to provide a servicing activity with respect to any of the OREO.

(5) Except as Previously Disclosed, all loans made by any of the FNB Companies to facilitate the disposition of OREO are performing in accordance with their terms.

(6) The allowance for possible loan losses shown on the FNB Financial Statements was, and the allowance for possible loan losses shown on the financial statements of FNB as of dates subsequent to the execution of this Agreement will be, in each case as of the dates thereof, adequate in all material respects to provide for possible losses, net of recoveries relating to loans previously charged off, on loans outstanding (including accrued interest receivable) of the FNB Companies and other extensions of credit (including letters of credit and commitments to make loans or extend credit) by FNB.

(r) Absence of Material Changes and Events. Since December 31, 1999, there has not been any material adverse change in the condition (financial or otherwise), aggregate assets or liabilities, cash flow, earnings or business or FNB, and FNB has conducted its business only in the ordinary course consistent with past practice.

(s) Statements True and Correct. None of the information supplied or to be supplied by FNB for inclusion in the Registration Statement, the proxy statement/prospectus or any other document to be filed with the SEC or any other regulatory authority in connection with the transactions contemplated hereby, will, at the respective time such documents are filed, and, in the case of the Registration Statement, when it becomes effective and with respect to the proxy statement/prospectus, when first mailed to SWVA shareholders, be false or misleading with respect to any material fact or omit to state any material fact necessary in order to make the statements therein not misleading, or, in the case of the proxy statement/prospectus or any supplement thereto, at the time of the SWVA Shareholders' Meeting, be false or misleading with respect to any material fact or omit to state any material fact necessary to correct any statement in any earlier communication with respect to the solicitation of any

25

proxy for the SWVA Shareholders' Meeting. All documents that FNB is responsible for filing with the SEC or any other regulatory authority in connection with the transactions contemplated hereby will comply as to form in all material respects with the provisions of applicable law, including applicable provisions of federal and state securities law.

(t) Brokers and Finders. Neither FNB nor any FNB Subsidiary, nor any of their respective officers, directors or employees, has employed any broker, finder or financial advisor or incurred any liability for any fees or commissions in connection with the transactions contemplated herein, except for The Carson Medlin Company.

(u) Repurchase Agreements. With respect to all agreements pursuant to which FNB or any FNB Subsidiary has purchased securities subject to an agreement to resell, if any, FNB or such FNB Subsidiary, as the case may be, has a valid, perfected first lien or security interest in the government securities or other collateral securing the repurchase agreement, and the value of such collateral equals or exceeds the amount of the debt secured thereby.

(v) Administration of Trust Accounts. FNB and FNB Subsidiaries have properly administered, in all respects material and which could reasonably be expected to be material to the business, operations or financial condition of FNB and FNB Subsidiaries, taken as a whole, all accounts for which they act as fiduciaries including but not limited to accounts for which they serve as trustees, agents, custodians, personal representatives, guardians, conservators or investment advisors, in accordance with the terms of the governing documents and applicable state and federal law and regulation and common law. Neither FNB nor a FNB Subsidiary, nor any director, officer or employee of FNB or a FNB Subsidiary has committed any breach of trust with respect to any such fiduciary account which is material to or could reasonably be expected to be material to the business, operations or financial condition of FNB, or a FNB Subsidiary, taken as a whole, and the accountings for each such fiduciary account are true and correct in all material respects and accurately reflect the assets of such fiduciary account in all material respects.

(w) Environmental Matters. (1) Except as Previously Disclosed, to the best of FNB's knowledge, neither FNB nor any FNB Subsidiary owns or leases any properties affected by toxic waste, radon gas or other hazardous conditions or constructed in part with the use of asbestos. Each of FNB and the FNB Subsidiaries is in substantial compliance with all Environmental Laws applicable to real or personal properties in which it has a direct fee ownership or, with respect to a direct interest as lessee, applicable to the leasehold premises or, to the best knowledge of FNB and the FNB Subsidiaries, the premises on which the leasehold is situated. Neither FNB nor any FNB Subsidiary has received any Communication alleging that FNB or such FNB Subsidiary is not in such compliance and, to the best knowledge of FNB and the FNB Subsidiaries, there are no present circumstances (including Environmental Laws that have been adopted but are not yet effective) that would prevent or interfere with the continuation of such compliance.

26

(2) There are no legal, administrative, arbitral or other claims, causes of action or governmental investigations of any nature, seeking to impose, or that could result in the imposition, on FNB and the FNB Subsidiaries of any liability arising under any Environmental Laws pending or, to the best knowledge of FNB and the FNB Subsidiaries, threatened against (A) FNB or any FNB Subsidiary, (B) any person or entity whose liability for any Environmental Claim, FNB or any FNB Subsidiary has or may have retained or assumed either contractually or by operation of law, or (C)any real or personal property which FNB or any FNB Subsidiary owns or leases, or has been or is judged to have managed or to have supervised or participated in the management of, which liability might have a material adverse effect on the business, financial condition or results of operations of FNB. FNB and the FNB Subsidiaries are not subject to any agreement, order, judgment, decree or memorandum by or with any court, governmental authority, regulatory agency or third party imposing any such liability.

(3) To the best knowledge of FNB and the FNB Subsidiaries, there are no legal, administrative, arbitral or other proceedings, or Environmental Claims or other claims, causes of action or governmental investigations of any nature, seeking to impose, or that could result in the imposition, on FNB or any FNB Subsidiary of any liability arising under any Environmental Laws pending or threatened against any real or personal property in which FNB or any FNB Subsidiary holds a security interest in connection with a loan or a loan participation which liability might have a material adverse effect on the business, financial condition or results of operations of FNB. FNB and the FNB Subsidiaries are not subject to any agreement, order, judgment, decree or memorandum by or with any court, governmental authority, regulatory agency or third party imposing any such liability.

(4) With respect to all real and personal property owned or leased by FNB or any FNB Subsidiary, other than OREO, FNB has made available to SWVA copies of any environmental audits, analyses and surveys that have been prepared relating to such properties. With respect to all OREO held by FNB or any FNB Subsidiary and all real or personal property which FNB or any FNB Subsidiary has been or is judged to have managed or to have supervised or participated in the management of, FNB has made available to SWVA the information relating to such OREO available to FNB. FNB and the FNB Subsidiaries are in compliance in all material respects with all recommendations contained in any environmental audits, analyses and surveys relating to any of the properties, real or personal, described in this subsection (4).

(5) There are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release, emission, discharge or disposal of any Materials of Environmental Concern, that could reasonably form the basis of any Environmental Claim or other claim or action or governmental investigation that could result in the imposition of any liability arising under any Environmental Laws currently in effect or adopted but not yet effective against FNB or any FNB Subsidiary or against any person or entity whose liability for any Environmental Claim FNB or any FNB Subsidiary has or may have retained or assumed either contractually or by operation of law.

Prior to the Effective Date, FNB, on the one hand, and SWVA on the other, agree to give to the other party reasonable access to all the premises and books and records (including tax returns filed and those in preparation) of it and its subsidiaries and to cause its officers to furnish the other with such financial and operating data and other information with respect to the business and properties as the other shall from time to time request for the purposes of verifying the warranties and representations set forth herein; provided, however, that any such investigation shall be conducted in such manner as not to interfere unreasonably with the operation of the respective business of the other.

5.2 Confidentiality. Between the date of this Agreement and the Effective Date, FNB and SWVA each will maintain in confidence, and cause its directors, officers, employees, agents and advisors to maintain in confidence, and not use to the detriment of the other party, any written, oral or other information obtained in confidence from the other party or a third party in connection with this Agreement or the transactions contemplated hereby unless such information is already known to such party or to others not bound by a duty of confidentiality or unless such information becomes publicly available through no fault of such party, unless use of such information is necessary or appropriate in making any filing or obtaining any consent or approval required for the consummation of the transactions contemplated hereby or unless the furnishing or use of such information is required by or necessary or appropriate in connection with legal proceedings. If the Merger is not consummated, each party will return or destroy as much of such written information as may reasonably be requested.

5.3 Registration Statement, Proxy Statement and Shareholder Approval. The Board of Directors of SWVA will duly call and will hold a meeting of its shareholders as soon as practicable for the purpose of approving the Merger (the "SWVA Shareholders' Meeting") and, subject to the fiduciary duties of the Board of Directors of SWVA (as determined after consultation with its counsel and as presented in writing), SWVA shall use its best efforts to solicit and obtain votes of the holders of its Common Stock in favor of the Merger and will comply with the provisions in its Articles of Incorporation and Bylaws relating to the call and holding of a meeting of shareholders for such purpose; and SWVA shall, at its own discretion, recess or adjourn the meeting if such recess or adjournment is deemed by SWVA to be necessary or desirable.

When the Registration Statement or any post-effective amendment or supplement thereto shall become effective, and at all times subsequent to such effectiveness, up to and including the date of the SWVA Shareholders' Meeting, such Registration Statement and all amendments or supplements thereto, with respect to all information set forth therein furnished or to be furnished by SWVA relating to the SWVA Companies and by FNB relating to

28

the FNB Companies, (i) will comply in all material respects with the provisions of the Securities Act of 1933 and any other applicable statutory or regulatory requirements, including applicable state blue-sky and securities laws, and (ii) will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements contained therein not misleading; provided, however, in no event shall any party hereto be liable for any untrue statement of a material fact or omission to state a material fact in the Registration Statement made in reliance upon, and in conformity with, written information concerning another party furnished by such other party specifically for use in the Registration Statement.

5.4 Operation of the Business of FNB and SWVA. From the date hereof to the Effective Date, FNB and SWVA will operate their respective businesses substantially as presently operated and only in the ordinary course, and, consistent with such operation, they will use their best efforts to preserve intact their relationships with persons having business dealings with them. Without limiting the generality of the foregoing, and except as provided in
Section 5.12, neither FNB nor SWVA will, without the prior written consent of the other, which consent shall not be unreasonably withheld:

(a) Make any change in its authorized capital stock, or issue or sell any additional shares of, securities convertible into or exchangeable for, or options (excluding those options provided for in the 2000 FNB Corporation Incentive Stock Compensation Plan, but the number of such options to be issued shall not exceed 50,000), warrants or rights to purchase, its capital stock, nor shall it purchase, redeem or otherwise acquire any of its outstanding shares of capital stock, provided that FNB or SWVA may issue shares of common stock pursuant to options granted or issued prior to the date hereof and FNB may repurchase FNB Common Stock consistent with past practices;

(c) Make any change in the compensation or title of any officer, director or key management employee or make any change in the compensation or title of any other employee, other than permitted by current employment policies in the ordinary course of business, any of which changes shall be reported promptly to the other party provided, however, that on or before the Effective Date, SWVA may extend the term of the employment agreements of D. W. Shilling and Barbara Weddle for terms not to exceed 36 months and 12 months from the Effective Date, respectively;

(d) Enter into any bonus, incentive compensation, stock option, deferred compensation, profit sharing, thrift, retirement, pension, group

29

insurance or other benefit plan or any employment or consulting agreement (excluding calendar year bonuses and 2001 Sales Incentives consistent with past practice);

(e) Incur any obligation or liability (whether absolute or contingent, excluding suits instituted against it), make any pledge, or encumber any of its assets, nor dispose of any of its assets in any other manner, except in the ordinary course of its business and for adequate value, or as otherwise specifically permitted in this Agreement, and excluding FHLB borrowings consistent with past practice;

(g) Knowingly waive any right to substantial value;

(h) Enter into material transactions otherwise than in the ordinary course of its business;

(i) Alter, amend or repeal its Bylaws or Articles of Incorporation (excluding any amendment with respect to SVSB in order to add one director to SVSB's Board); or

5.6 No Solicitation. Without the prior written consent of FNB, SWVA shall not, and shall cause its officers, directors, agents, advisors and affiliates not to, solicit or encourage inquires or proposals with respect to, furnish any information relating to, or participate in any negotiations or discussions concerning, an Acquisition Transaction (as hereinafter defined); provided, however, that nothing contained in this Section 5.6 shall prohibit the Board of Directors of SWVA from furnishing information to, or entering into discussions or negotiations with, any person or entity that makes an unsolicited, written bona fide proposal regarding an Acquisition Transaction if, and only to the extent that (A) the Board of Directors of SWVA concludes in good faith, after consultation with and consideration of the written advice of outside counsel, that the failure to furnish such information or enter into such discussions or negotiations would constitute a breach of its fiduciary duties to shareholders under applicable law, and (B) the Board of Directors of SWVA concludes in good faith that the proposal regarding the Acquisition Transaction contains an offer of consideration that is superior to the consideration set forth herein. SWVA shall immediately notify FNB orally and in writing of its receipt of any such proposal or inquiry, of the material terms and conditions thereof, and, if possible, of the identity of the person making such proposal or

30

inquiry. For purposes of this Agreement, "Acquisition Transaction" means any merger, consolidation, share exchange, joint venture, business combination or similar transaction or any purchase of all or any material portion of the assets of an entity.

5.7 Regulatory Filings. FNB and SWVA shall prepare jointly all regulatory filings required to consummate the transactions contemplated by the Agreement and the Plan of Merger and submit the filings for approval with the Federal Reserve Board and the SCC, and any other governing regulatory authority, as soon as practicable after the date hereof. FNB and SWVA shall use their best efforts to obtain approvals of such filings.

5.8 Public Announcements. Each party will consult with the other before issuing any press release or otherwise making any public statements with respect to the Merger and shall not issue any such press release or make any such public statement prior to such consultations except as may be required by law.

5.9 Notice of Breach. FNB and SWVA will give written notice to the other promptly upon becoming aware of the impending or threatened occurrence of any event which would cause or constitute a breach of any of the representations, warranties or covenants made to the other party in this Agreement and will use its best efforts to prevent or promptly remedy the same.

5.10 Accounting Treatment. FNB and SWVA acknowledge that the Merger shall be accounted for as a purchase under generally accepted accounting principles.

5.11 Merger Consummation. Subject to the terms and conditions of this Agreement, each party shall use its best efforts in good faith to take, or cause to be taken, all actions, and to do or cause to be done all things necessary, proper or desirable, or advisable under applicable laws, as promptly as practicable so as to permit consummation of the Merger at the earliest possible date, consistent with Section 1.5 herein, and to otherwise enable consummation of the transactions contemplated hereby and shall cooperate fully with the other parties hereto to that end, and each of FNB and SWVA shall use, and shall cause each of their respective subsidiaries to use, its best efforts to obtain all consents (governmental or other) necessary or desirable for the consummation of the transactions contemplated by this Agreement.

5.12 FNB Acquisition Transaction. Nothing contained in this Agreement shall prevent FNB from entering into an Acquisition Transaction with a third party so long as FNB and its successors comply with the terms of the Merger with SWVA.

5.13 Affiliate Agreements. SWVA shall use its best efforts to cause each director, executive officer and other person who is an "affiliate" of SWVA under Rule 145 of the Securities Act to deliver to FNB as soon as practicable, and prior to the mailing of the proxy statement/prospectus, executed letter

31

agreements in the form of Exhibit C attached hereto providing that such person will comply with Rule 145 and will vote in favor of the Merger.

ARTICLE 6
Additional Agreements

6.1 Conversion of Stock Options. (a) On the Effective Date, all rights with respect to SWVA Common Stock pursuant to stock options ("SWVA Options") granted by SWVA under a SWVA stock option plan which are outstanding on the Effective Date, whether or not they are exercisable, shall be converted into and become rights with respect to FNB Common Stock, and FNB shall assume each SWVA Option in accordance with the terms of the stock option plan under which it was issued and the stock option agreement by which it is evidenced. From the Effective Date forward, (i) each SWVA Option assumed by FNB may be excised solely for shares of FNB Common Stock, (ii) the number of shares of FNB Common Stock subject to each SWVA Option shall be equal to the number of shares of SWVA Common Stock subject to such option immediately prior to the Effective Date multiplied by the Exchange Ratio and (iii) the per share exercise price under each such SWVA Option shall be adjusted by dividing the per share exercise price under each such option by the Exchange Ratio and rounding down to the nearest cent; provided, however, that the terms of each SWVA Option shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, stock dividend, recapitalization or other similar transaction after the Effective Date. It is intended that the foregoing assumption shall be undertaken in a manner that will not constitute a "modification" as defined in Section 425 of the Code, as to any stock option which is an "incentive stock option." Shares of FNB Common Stock issuable upon exercise of SWVA Options shall be covered by an effective registration statement on Form S-8, and FNB shall use its reasonable best efforts to file a registration statement on Form S-8 covering such shares as soon as possible after the Effective Date, but in no event, no later than 30 days after the Effective Date.

6.2 Benefit Plans.

(a) Effective with the consummation of the Merger, the Management Stock Bonus Plan of SVSB shall be terminated and all unawarded shares (and the Merger Consideration attributable thereto) shall be forfeited to SVSB. In addition, the SVSB ESOP (as defined in Section 6.2(c)) shall be continued and then merged as provided Section 6.2(c) below, the SVSB Defined Benefit Plan (as defined in Section 6.2(d)) shall be continued and then terminated as provided
Section 6.2(d) below, and participation in the FNB 401(k) plan shall be made available to SVSB employees as provided Section 6.2(e) below. Otherwise, after consummation of the Merger, at the option of FNB (which may be applied on a plan or program by plan or program basis) and subject to FNB's best efforts, employees of SWVA and SVSB shall be entitled to participate either (x) in one or more combined plans or programs of FNB and SWVA on substantially the same basis as similarly situated employees of FNB or First National (taking into account all applicable factors, including but not limited to position, employment classification, age, length of service, pay, part time or full time status, and the like, as well as changes made in such plans and programs in the future), or
(y) in plans and programs which, subject to changes required by applicable laws

32

or by limitations imposed by insurance companies providing plan benefits, are comparable to (or a continuation of), and provide for participation on substantially the same basis, as SWVA's employee benefit plans and programs currently in effect. If and to the extent option (x) is effectuated:

(1) (A) Coverage under FNB's plans and programs shall be available to each employee of SWVA and SVSB and his or her dependents without regard to any waiting period, evidence or requirement of insurability, actively at work requirement or preexisting condition exclusion or limitation (except to the extent and in the manner any such waiting period, evidence or requirement of insurability, actively at work requirement or exclusion or limitation applies to such employee or dependents immediately prior to the effectuation of option (x)) and (B) amounts paid or payable by employees for health care expenses for the portion of the annual benefit period prior to the date as of which option (x) becomes effective shall be credited in satisfaction of any deductible requirement and any out-of-pocket limit for the balance of the annual benefit period which includes such date.

(2) FNB shall treat service with SWVA and SVSB before the consummation of the Merger as service with FNB for purposes of eligibility to begin participation and vesting (but not benefit accruals, except in the case of a continuation of any plan maintained by SWVA or SVSB) for purposes of all employee benefit and seniority based plans and programs, including but not limited to annual, sick and personal leave accruing following the consummation of the Merger.

Nothing contained in this Section is intended to provide any third party beneficiary rights in any current or former employee, or any spouse or dependent thereof, of SWVA, SVSB, FNB or any FNB Subsidiary, except as otherwise required by ERISA or other applicable law (determined without regard to third party beneficiary contract law).

(b) Except to extent individually negotiated replacement contracts or settlement agreements are entered into, FNB shall honor all employment severance, consulting and other compensation contracts and agreements Previously Disclosed and executed in writing by SWVA on the one hand and any individual current or former director, officer or employee thereof on the other hand, copies of which have been previously delivered by SWVA to FNB.

(c) As of the Effective Date, all SWVA and SVSB employees who are participants in the SVSB Employee Stock Ownership Plan (the "SVSB ESOP") shall be fully vested in their accrued benefits under the SVSB ESOP, and the SVSB ESOP shall be continued and shall be merged into the FNB Employee Stock Ownership Plan no later than two years after the Merger, with participation in the FNB Employee Stock Ownership Plan extended to eligible employees of SVSB as of the time of such plan merger. FNB shall treat service with SWVA and SVSB before the consummation of the Merger as service with FNB for purposes of eligibility to begin participation, vesting and future benefit accrual under its Employee Stock Ownership Plan.

33

(d) As of the Effective Date, all SWVA and SVSB employees who are participants in the SWVA defined benefit plan maintained through the Financial Institutions Retirement Fund (the "SWVA Defined Benefit Plan") shall be fully vested in their accrued benefits under the SWVA Defined Benefit Plan, and all necessary steps shall be taken to cause the SWVA Defined Benefit Plan to be terminated no later than the end of its plan year in which the Merger occurs, in accordance with applicable law. If the SWVA Defined Benefit Plan is fully funded on termination, any funding surplus shall be used to increase accrued benefits on a basis which is nondiscriminatory under the IRC in a manner mutually agreeable to FNB, SWVA and SVSB.

(e) Effective no later than the beginning of the first plan year of FNB's 401(k) plan commencing after the effective date of the termination of the SWVA Defined Benefit Plan, FNB shall make participation in its 401(k) plan available to the eligible employees of SWVB. FNB shall treat service with SWVA and SVSB before the consummation of the Merger as service with FNB for purposes of eligibility to begin participation, vesting and future benefit accrual under its 401(k) plan.

6.3 Indemnification. Following the Effective Date, FNB shall indemnify and hold harmless any person who has rights to indemnification from SWVA, to the maximum extent permitted under Virginia law and in accordance with SWVA's Articles of Incorporation or Bylaws, as in effect on the date of this Agreement, to the extent legally permitted to do so, with respect to matters occurring on or prior to the Effective Date. FNB further agrees that any such person who has rights to indemnification pursuant to this Section 6.3 is expressly made a third party beneficiary of this Section 6.3 and may directly, in such person's personal capacity, enforce such rights through an action at law or in equity or through any other manner or means of redress allowable under Virginia law to the same extent as if such person were a party hereto. Without limiting the foregoing, in any case in which corporate approval may be required to effectuate any indemnification, FNB shall direct, at the election of the party to be indemnified, that the determination of permissibility of indemnification shall be made by independent counsel mutually agreed upon between FNB and the indemnified party. Upon written application, and in accordance with, and to the extent permitted by, Virginia law, FNB will advance reasonable expenses to any person who has rights to indemnification from SWVA. FNB shall use its reasonable best efforts to maintain SWVA's existing directors' and officers' liability policy, or some other policy, including FNB's existing policy, providing at least comparable coverage, covering persons who are currently covered by such insurance of SWVA for a period of six years after the Effective Date on terms no less favorable than those in effect on the date hereof.

EXHIBIT A
to the
Agreement and Plan
of Merger

PLAN OF MERGER
BETWEEN
SWVA BANCSHARES, INC.
AND
FNB CORPORATION

Pursuant to this Plan of Merger ("Plan of Merger"), SWVA Bancshares, Inc. ("SWVA"), a Virginia corporation, shall merge with and into FNB Corporation ("FNB"), a Virginia corporation in a merger under Section 13.1-716 of the Virginia Stock Corporation Act.

ARTICLE 1
Terms of the Merger

1.1 The Merger. Subject to the terms and conditions of the Agreement and Plan of Merger, dated as of August ___, 2000 between FNB and SWVA (the "Merger Agreement"), at the Effective Date, SWVA shall merge with and into FNB , which shall be the surviving corporation. Each outstanding share of common stock of SWVA shall be converted into and exchanged for shares of the common stock of FNB and/or cash in accordance with Article 2 of this Plan of Merger pursuant to a merger under Section 13.1-716 of the Virginia Stock Corporation Act (the "Merger"). At the Effective Date, the Merger shall have the effect as provided in Section 13.1-721 of the Virginia Stock Corporation Act.

1.2 Articles of Incorporation and Bylaws. The Articles of Incorporation of FNB shall be the Articles of Incorporation of the surviving corporation following the Effective Date until amended or repealed. The Bylaws of FNB shall be the Bylaws of the surviving corporation following the Effective Date until amended or repealed in accordance with the terms of such Bylaws.

1.3 Management of Surviving Corporation. On the Effective Date, the number of Directors of FNB shall be increased by two members by adding one member in Class I whose terms expire at the 2003 annual meeting of shareholders and by adding one member in Class III whose terms expire at the 2002 annual meeting of shareholders. B. L. Rakes shall be appointed to fill the vacancy created in Class I and Courtney Hoge shall be appointed to fill the vacancy created in Class III. At the next annual meeting of shareholders of FNB, management of FNB will recommend to shareholders that those gentlemen be elected as a member of Class I and Class III, respectively. In addition, on the Effective Date, FNB agrees to assume the employment agreements between SWVA and D. W. Shilling and Barbara Weddle, and as of the Effective Time, FNB shall enter into an Addendum to the employment agreement for D. W. Shilling and Barbara Weddle, as attached as Exhibit 1.4 to the Merger Agreement. In addition, as of the Effective Date, FNB shall enter into an agreement with B. L. Rakes in which FNB agrees to pay Mr. Rakes $17,000 in consideration for his agreement not to compete with FNB and its affiliates for a period of one year.


ARTICLE 2
Manner of Converting Shares

2.1 Conversion of SWVA Stock and Stock Options. At the Effective Date, by virtue of the Merger, each share of the common stock, par value $0.10 per share, of SWVA ("SWVA Common Stock") issued and outstanding immediately prior to the Effective Date will be converted into either cash (the "Cash Consideration") or shares of common stock, par value $5.00 per share, of FNB ("FNB Common Stock"), the "Stock Consideration," which Stock Consideration together with the Cash Consideration (the "Merger Consideration"), in each case as the holder thereof shall have elected or be deemed to have elected in accordance with Section 2.3.

In the case that the Market Value of FNB Common Stock (as defined later in this Section 2.1) is equal to or greater than $15.30 per share and equal to or less than $18.70 per share, the Cash Consideration will be $20.25 per share and the Stock Consideration will equal shares of FNB Common Stock with a Market Value of $20.25. In the case that the Market Value of FNB Common Stock is greater than $18.70 and less than or equal to $20.00, the Stock Consideration will equal 1.083 shares of FNB Common Stock for each outstanding share of SWVA Common Stock, and the Cash Consideration will be $20.25. In the case that the Market Value of FNB Common Stock is less than $15.30 and equal to or greater than $14.00, the Stock Consideration will equal 1.324 shares of FNB Common Stock for each outstanding share of SWVA Common Stock, and the Cash Consideration will be $20.25.

The Market Value of FNB Common Stock will be the average of the last reported sales prices per share of FNB Common Stock as reported on the NASDAQ Exchange Composite Transactions Tape (as reported in The Wall Street Journal, or, if not reported thereby, another authoritative source as chosen by FNB) for the thirty consecutive full trading days on such exchange (even if FNB Common Stock does not trade in each such day) ending at the close of trading on the tenth calendar day before the Effective Date (the "Market Value" and the Measurement Period"). The ratio of shares of FNB's common stock that will be exchanged for each outstanding share of SWVA Common Stock shall be referred to herein as the "Exchange Ratio" and shall be rounded to the nearest thousandth decimal point.

2.2 Allocation. Notwithstanding anything in this Plan of Merger to the contrary, the aggregate amount of cash to be issued to shareholders of SWVA in the Merger shall be equal to $1,785,742 (the "Cash Amount"); provided that the Cash Amount may be changed by FNB to accommodate the exercise by FNB of its option to change the Cash Number and the Stock Number pursuant to the last sentence of this Section 2.2. As used in the Merger Agreement, the Cash Number shall mean the aggregate number of shares of SWVA Common Stock to be converted into the right to receive the Cash Consideration in the Merger, which shall be equal to the Cash Amount divided by $20.25. The number of shares of SWVA Common Stock to be converted into the right to receive Stock Consideration (the "Stock Number") will be equal to (i) the number of shares of SWVA Common Stock issued and outstanding immediately prior to the Effective Date of the Merger less (ii) the sum of (A) the Cash Number and (B) the aggregate number of shares of SWVA Common Stock to be exchanged for cash pursuant to Section 3.3. FNB shall have

2

the option to change the Cash Number and the Stock Number to more closely follow the actual elections of SWVA shareholders pursuant to this Article 2, so long as such modification to the Cash Number and the Stock Number does not prevent the condition set forth in Section 7.1(d) of the Merger Agreement from being satisfied.

2.3 Election. Subject to allocation in accordance with the provisions of this Article, each record holder of shares of SWVA Common Stock issued and outstanding immediately prior to the Election Deadline (as defined in Section 3.1(i)) will be entitled, in accordance with Section 3.1, (i) to elect to receive in respect of each such share held in such manner (A) Cash Consideration (a "Cash Election") or (B) Stock Consideration (a "Stock Election") thus, making an election for all Cash Consideration, all Stock Consideration, or a mixture thereof or (ii) to indicate that such record holder has no preference as to the receipt of Cash Consideration or Stock Consideration for all such shares held by such holder (a "Non-Election"). Shares of SWVA Common Stock in respect of which a Non-Election is made or as to which no election is made (collectively, "Non- Election Shares") shall be deemed by FNB to be shares in respect of which Cash Elections or Stock Elections have been made, as FNB shall determine. Holders of record of shares of SWVA Common Stock who hold such shares as nominees, trustees or in other representative capacities (a "Representative") may submit multiple Forms of Election (as hereinafter defined), provided that each such Form of Election covers all the shares of SWVA Common Stock held by that Representative for a particular beneficial owner.

2.4 Allocation of Cash Election Shares. In the event that the aggregate number of shares in respect of which Cash Elections have been made (the "Cash Election Shares") exceeds the Cash Number, all shares of SWVA Common Stock in respect of which Stock Elections have been made (the "Stock Election Shares") and all Non-Election Shares will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with
Section 3.3), and Cash Election Shares will be converted into the right to receive Cash Consideration or Stock Consideration in the following manner:

(i) the number of Cash Election Shares covered by each Form of Election (as defined in Section 3.1(i)) to be converted into Cash Consideration will be determined by multiplying the number of Cash Election Shares covered by such Form of Election by a fraction, (A) the numerator of which is the Cash Number and (B) the denominator of which is the aggregate number of Cash Election Shares rounded down to the nearest whole number; and

(ii) all Cash Election Shares not converted into Cash Consideration in accordance with Section 2.4(i) will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3).

Provided, however, that cash in lieu of fractional interests and cash to be paid in connection with rights of dissenting shareholders, as provided in Sections 3.3 and 3.5, respectively, shall not be included in any determination of whether this Section 2.4 shall be given effect.

2.5 Allocation of Stock Election Shares. In the event that the aggregate number of Stock Election Shares exceeds the Stock Number, all Cash Election Shares and all Non-Election Shares (together, the " Cash Shares") will

3

be converted into the right to receive Cash Consideration, and all Stock Election Shares will be converted into the right to receive Cash Consideration or Stock Consideration in the following manner:

(i) the number of Stock Election Shares covered by each Form of Election to be converted into Cash Consideration will be determined by multiplying the number of Stock Election Shares covered by such Form of Election by a fraction, (A) the numerator of which is the Cash Number less the number of Cash Shares and (B) the denominator of which is the aggregate number of Stock Election Shares, rounded down to the nearest whole number; and

(ii) all Stock Election Shares not converted into Cash Consideration in accordance with Section 2.5(i) will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3).

2.6 No Allocation. In the event that neither Section 2.4 nor Section 2.5 is applicable, all Cash Election Shares will be converted into the right to receive Cash Consideration, all Stock Election Shares will be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3) and Non-Election Shares will be converted into the right to receive Cash Consideration or Stock Consideration (and cash in lieu of fractional interests in accordance with Section 3.3) as the Exchange Agent shall determine.

2.7 Computations. The Exchange Agent (as defined in Section 3.1(i)) will make all computations to give effect to this Article 2.

2.8 Cancellation of Shares. As of the Effective Date of the Merger, all such shares of SWVA Common Stock will no longer be outstanding and automatically be cancelled and retired and will cease to exist and each holder of a certificate formerly representing any such shares of SWVA Common Stock (a "SWVA Certificate") will cease to have any rights with respect thereto, except the right to receive Merger Consideration and any additional cash in lieu of fractional shares of FNB Common Stock to be issued or paid in consideration therefor upon surrender of such SWVA Certificate in accordance with Article 3, without interest, subject to rights of dissenting shareholders as provided under
Section 3.5.

(i) Not more than 45 days nor fewer than 30 days prior to the Effective Date, First National Bank, Christiansburg, Virginia, as the exchange agent ("Exchange Agent"), will mail a form of election (the "Form of Election") to each shareholder of record of SWVA as of a record date as close as practicable to the date of mailing and mutually agreed to by SWVA and FNB. The Exchange Agent shall enter into a written agreement with FNB and SWVA detailing its duties and

4

responsibilities and shall furnish evidence of liability insurance for such activities in a form substantially similar to Exhibit C to the Merger Agreement. In addition, the Exchange Agent will use its best efforts to make the Form of Election available to the persons who become shareholders of SWVA during the period between such record date and the Effective Date. Any election to receive Merger Consideration will have been properly made only if the Exchange Agent shall have received on the fifth business day immediately preceding the Effective Date (the "Election Deadline"), a Form of Election properly completed and accompanied by a SWVA Certificate ("Certificate(s)") for the shares to which such Form of Election relates, acceptable for transfer on the books of SWVA (or an appropriate guarantee of delivery), as set forth in such Form of Election. An election may be revoked only by written notice received by the Exchange Agent prior to 5:00 p.m. on the Election Deadline. If an election is so revoked, the Certificate(s) (or guarantee of delivery, as appropriate) to which such election relates will be promptly returned to the person submitting the same to the Exchange Agent.

(ii) As soon as reasonably practicable after the Effective Date, the Exchange Agent will mail to each holder of record of a Certificate, whose shares of SWVA Common Stock were converted into the right to receive Merger Consideration and those who failed to return a properly completed Form of Election, (i) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon delivery of the Certificates to the Exchange Agent and will be in such form and have such other provisions as the Exchange Agent may specify consistent with the Merger Agreement) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration.

(iii) With respect to properly made elections in accordance with
Section 3.1(i), and upon surrender in accordance with Section 3.1(ii) of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate will be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive pursuant to the provisions of Article 2, and the Certificate so surrendered will forthwith be canceled. In the event of a transfer of ownership of Shares that are not registered in the transfer records of SWVA, as the case may be, payment may be issued to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate is properly endorsed or otherwise in proper form for transfer and the person requesting such issuance pays any transfer or other taxes required by reason of such payment to a person other than the registered holder of such Certificate or establishes to the satisfaction of FNB that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 3.1, each Certificate will be deemed at any time after the Effective Date to represent only the right to receive upon such surrender the Merger Consideration that the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of Article 2. No interest will be paid or will accrue on any cash payable to holders of Certificates pursuant to the provisions of Article 2.

5

3.2 Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to the shares of SWVA Common Stock with a record date after the Effective Date shall be paid to the holder of any unsurrendered Certificate with respect to the shares of SWVA Common Stock represented thereby, and no cash payment in lieu of any fractional shares shall be paid to any such holder pursuant to Section 3.3. Subject to the effect of unclaimed property, escheat and other applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the Certificate representing whole shares of SWVA Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of SWVA Common Stock to which such holder is entitled pursuant to Section 3.3, and (ii) the amount of dividends or other distributions, if any, with a record date after the Effective Date.

3.3 No Fractional Securities. No FNB Certificates or scrip representing fractional shares of FNB Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional shares shall not entitle the owner thereof to vote or to any other rights of a holder of FNB Common Stock. A holder of Shares converted in the Merger who would otherwise have been entitled to a fractional share of FNB Common Stock shall be entitled to receive a cash payment (without interest) in lieu of such fractional share in an amount determined by multiplying (i) the fractional share interest to which such holder would otherwise be entitled by (ii) the Market Value of FNB Common Stock.

3.4 Certain Adjustments. If, after the date hereof and on or prior to the Closing Date, the outstanding shares of SWVA Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination or exchange of shares, or any dividend payable in stock or other securities is declared thereon with a record date within such period, or any similar event shall occur, the Merger Consideration will be adjusted accordingly to provide to the holders of SWVA Common Stock, respectively, the same economic effect as contemplated by the Merger Agreement prior to such reclassification, recapitalization, split-up, combination, exchange or dividend or similar event.

3.5 Rights of Dissenting Shareholders. Shareholders of SWVA who object to the Merger will be entitled to the rights and remedies set forth in sections 13.1-729 through 13.1-741 of the Virginia Stock Corporation Act.

ARTICLE 4
Treatment of Stock Options

4.1 Conversion of Stock Options. (a) On the Effective Date, all rights with respect to SWVA Common Stock pursuant to stock options ("SWVA Options") granted by SWVA under a SWVA stock option plan which are outstanding on the Effective Date, whether or not they are exercisable, shall be converted into and become rights with respect to FNB Common Stock, and FNB shall assume each SWVA Option in accordance with the terms of the stock option plan under which it was issued and the stock option agreement by which it is evidenced. From the Effective Date forward, (i) each SWVA Option assumed by FNB may be excised solely for shares of FNB Common Stock, (ii) the number of shares of FNB Common Stock subject to each SWVA Option shall be equal to the number of shares of SWVA Common Stock subject to such option immediately prior to the Effective Date multiplied by the Exchange Ratio and (iii) the per share exercise price

6

under each such SWVA Option shall be adjusted by dividing the per share exercise price under each such option by the Exchange Ratio and rounding down to the nearest cent; provided, however, that the terms of each SWVA Option shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, stock dividend, recapitalization or other similar transaction after the Effective Date. It is intended that the foregoing assumption shall be undertaken in a manner that will not constitute a "modification" as defined in Section 425 of the Code, as to any stock option which is an "incentive stock option." Shares of FNB Common Stock issuable upon exercise of SWVA Options shall be covered by an effective registration statement on Form S-8, and FNB shall use its reasonable best efforts to file a registration statement on Form S-8 covering such shares as soon as possible after the Effective Date, but in no event, no later than 30 days after the Effective Date.

ARTICLE 5
Termination

5.1 Termination. This Plan of Merger may be amended or terminated prior to the Effective Time as provided in the Merger Agreement, subject to the provisions of the Virginia Stock Corporation Act.

WHEREAS, each of the Stockholders is the beneficial and registered owner of, and has or shares the right to vote and dispose of, the number of shares of common stock, par value $0.10 per share, of SWVA ("SWVA Common Stock") set forth opposite such Stockholder's name on Schedule A hereto (the "Shares") and has rights by option or otherwise to acquire additional shares of SWVA Common Stock also set forth opposite such Stockholder's name on Schedule A hereto;

1. Agreement to Vote. At such time as SWVA conducts a meeting of its stockholders, including any adjournments thereof, to approve the Affiliation Agreement, each Stockholder agrees to vote or cause to be voted all of such Stockholder's Shares in favor of the Affiliation Agreement, unless FNB is in material default with respect to any covenant, representation, warranty or agreement with respect to it contained in the Affiliation Agreement or the Affiliation Agreement provides otherwise.

4. Covenants of Stockholders. Each of the Stockholders, severally and not jointly, covenants as follows:

(a) Restrictions on Transfer. During the term of this Agreement and except as agreed to by FNB, such Stockholder shall not pledge, hypothecate, grant a security interest in, sell, transfer or otherwise dispose of or encumber any of the Shares owned by him or her and will not enter into any agreement, arrangement or understanding (other than a proxy for the purpose of voting his or her shares in accordance with Section 1 hereof) which would during that term

_____________ __, 2001

Board of Directors
SWVA Bancshares, Inc.
302 Second Street, S.W.
Roanoke, Virginia 24011

Members of the Board:

You have requested RP Financial, LC. ("RP Financial") to provide you with its opinion as to the fairness from a financial point of view to the stockholders of SWVA Bancshares, Inc., Roanoke, Virginia ("SWVA"), the holding company for Southwest Virginia Savings Bank, FSB ("Southwest Virginia"), of the Agreement and Plan of Merger (the "Agreement"), by and between FNB Corporation, Christiansburg, Virginia ("FNB"), a Virginia banking corporation, and SWVA. Unless otherwise defined, all capitalized terms incorporated herein have the meanings ascribed to them in the Agreement, which is incorporated herein by reference.

Summary Description of Consideration

At the Effective Time, SWVA shall be merged into FNB. Concurrently, each share of the common stock, par value $0.10 per share, of SWVA ("SWVA Common Stock"), issued and outstanding immediately prior to the Effective Date (except for dissenters' shares) will be converted into either cash (the "Cash Consideration") or shares of common stock, par value $5.00 per share, of FNB ("FNB Common Stock"), the "Stock Consideration". In the case that the Market Value of FNB Common Stock is equal to or greater than $15.30 per share and equal to or less than $18.70 per share, the Cash Consideration will be $20.25 per share and the Stock Consideration will equal shares of FNB Common Stock with a Market Value of $20.25. In the case that the Market Value of FNB Common Stock is greater than $18.70 and less than or equal to $20.00, the Stock Consideration will equal 1.083 shares of FNB Common Stock for each outstanding share of SWVA Common Stock, and the Cash Consideration will be $20.25. In the case that the Market Value of FNB Common Stock is less than $15.30 and equal to or greater than $14.00, the Stock Consideration will equal 1.324 shares of FNB Common Stock for each outstanding share of SWVA Common Stock, and the Cash Consideration will be $20.25.

The Market Value of FNB Common Stock will be the average of the last reported sales prices per share of FNB Common Stock as reported on the NASDAQ Exchange Composite Transactions Tape (as reported in The Wall Street Journal, or, if not reported thereby, another authoritative source as chosen by FNB) for the thirty consecutive full trading days on such exchange (even if FNB Common Stock does not trade in each such day) ending at the close of trading on the tenth calendar day before the Effective Date. The ratio of shares of FNB's Common Stock that will be exchanged for each outstanding share of SWVA Common Stock shall be referred to herein as the "Exchange Ratio" and shall be rounded to the nearest thousandth decimal point. As of the date hereof, SWVA had 423,612 shares of common stock issued and outstanding, and 64,049 granted stock options outstanding.

RP Financial Background and Experience

RP Financial, as part of its financial institution valuation and consulting practice, is regularly engaged in the valuation of financial institution securities in connection with mergers and acquisitions of commercial banks and thrift institutions, initial and secondary offerings, mutual-to-stock conversions of thrift institutions, and business valuations for other corporate purposes for financial institutions. As specialists in the securities of financial institutions, RP Financial has experience in, and knowledge of, the Virginia and Southeast U.S. markets for thrift and bank securities and financial institutions operating in Virginia.

Materials Reviewed

In rendering this fairness opinion, RP Financial reviewed the following material: (1) the Agreement, dated August 7, 2000, including exhibits; (2) financial and other information for SWVA, all with regard to balance and off- balance sheet composition, profitability, interest rates, volumes, maturities, trends, credit risk, interest rate risk, liquidity risk and operations: (a) audited and unaudited financial statements for the fiscal years ended June 30, 1995 through 2000, (b) stockholder, regulatory and internal financial and other reports through June 30, 2000, (c) the conversion prospectus, dated August 12, 1994, (d) the proxy statements for the last three years, and (e) SWVA's management and Board comments regarding past and current business, operations, financial condition, and future prospects; and (3) financial and other information for FNB including: (a) unaudited and audited financial statements for the fiscal years ended December 31, 1996 through 1999, (b) stockholder, regulatory, internal financial and/or other reports through June 30, 2000, (c) proxy statements for the last three years, (d) publicly-available information pertaining to the pending acquisition of CNB Holdings, Inc., holding company for Community National Bank, Pulaski, Virginia and (e) FNB's management comments regarding past and current business, operations, financial condition, and future prospects.

RP Financial reviewed financial, operational, market area and stock price and trading characteristics for SWVA and FNB (on a historical and pro forma basis) relative to publicly-traded savings institutions and commercial banking institutions, respectively, with comparable resources, financial condition, earnings, operations and markets. RP Financial also considered the economic and demographic characteristics in the local market area, and the potential impact of the regulatory, legislative and economic environments on operations for SWVA and FNB and the public perception of the savings institution and commercial

2

banking industries. RP Financial also considered: (1) the financial terms, financial and operating condition and market area of other recently completed acquisitions of comparable savings institutions both regionally and nationally;
(2) discounted cash flow analyses for SWVA incorporating future prospects; (3) expressions of interest by third parties seeking a business combination with SWVA; (4) the pro forma impact on FNB of the acquisitions of CNB Holdings, Inc. and SWVA, which are expected to be accounted for as purchases; and (5) the market for FNB's common stock.

In rendering its opinion, RP Financial relied, without independent verification, on the accuracy and completeness of the information concerning SWVA and FNB furnished by the respective institutions to RP Financial for review, as well as publicly-available information regarding other financial institutions and economic and demographic data. SWVA and FNB did not restrict RP Financial as to the material it was permitted to review. RP Financial did not perform or obtain any independent appraisals or evaluations of the assets and liabilities and potential and/or contingent liabilities of SWVA or FNB.

RP Financial expresses no opinion on matters of a legal, regulatory, tax or accounting nature or the ability of the merger as set forth in the Agreement to be consummated. In rendering its opinion, RP Financial assumed that, in the course of obtaining the necessary regulatory and governmental approvals for the proposed Merger, no restriction will be imposed on FNB that would have a material adverse effect on the ability of the Merger to be consummated as set forth in the Agreement.

Opinion

It is understood that this letter is directed to the Board of Directors of SWVA in its consideration of the Agreement, and does not constitute a recommendation to any stockholder of SWVA as to any action that such stockholder should take in connection with the Agreement, or otherwise.

It is understood that this opinion is based on market conditions and other circumstances existing on the date hereof.

It is understood that this opinion may be included in its entirety in any communication by SWVA or its Board of Directors to the stockholders of SWVA and that stockholders may rely on the opinion. It is also understood that this opinion may be included in its entirety in any regulatory filing by SWVA or FNB, and that RP Financial consents to the summary of the opinion in the proxy materials of SWVA, and any amendments thereto. Except as described above, this opinion may not be summarized, excerpted from or otherwise publicly referred to without RP Financial's prior written consent.

Based upon and subject to the foregoing, and other such matters considered relevant, it is RP Financial's opinion that, as of the date hereof, the Merger Consideration to be received by SWVA's stockholders, as described in the Agreement, is fair to such stockholders from a financial point of view.

Respectfully submitted,
RP FINANCIAL, LC.

ARTICLE 15 - CODE OF VIRGINIA

C-1

ARTICLE 15.

DISSENTERS' RIGHTS

ss.13.1-729. Definitions.--In this article:

"Corporation" means the issuer of the shares held by a dissenter before the corporate action, except that (i) with respect to a merger, "corporation" means the surviving domestic or foreign corporation or limited liability company by merger of that issuer, and (ii) with respect to a share exchange, "corporation" means the acquiring corporation by share exchange, rather than the issuer, if the plan of share exchange places the responsibility for dissenters' rights on the acquiring corporation.

"Dissenter" means a shareholder who is entitled to dissent from corporate action under ss. 13.1-730 and who exercises that right when and in the manner required by ss.13.1-732 through ss.13.1-739.

"Fair value," with respect to a dissenter's shares, means the value of the shares immediately before the effectuation of the corporate action to which the dissenter objects, excluding any appreciation or depreciation in anticipation of the corporate action unless exclusion would be inequitable.

"Interest" means interest from the effective date of the corporate action until the date of payment, at the average rate currently paid by the corporation on its principal bank loans or, if none, at a rate that is fair and equitable under all the circumstances.

"Record shareholder" means the person in whose name shares are registered in the records of a corporation or the beneficial owner of shares to the extent of the rights granted by a nominee certificate on file with a corporation.

"Beneficial shareholder" means the person who is a beneficial owner of shares held by a nominee as the record shareholder.


CODE OF VIRGINIA

ss 13.1-730

"Shareholder" means the record shareholder or the beneficial shareholder. (1985, C. 522; 1992,C. 575.)

Law Review.--For article, "Dissenting Stockholders' Rights in Virginia:
Exclusivity of the Cash-Out Remedy and Determination of 'Fair Value,'" see 12 U. Rich. L. Rev. 505 (1978). For article, "The New Virginia Stock Corporation Act:
A Primer," see 20 U. Rich. L. Rev. 67 (1985). For article, "Virginia's Affiliated Transactions' Statute: Indulging Form Over Substance in Second Generation Takeover Legislation," see 21 U. Rich. L. Rev. 489 (1987).

Editor's note.--The cases below were decided under prior law.

"Fair value" defined.--The term "fair value" of the stock of a stockholder who dissents from a sale means the intrinsic worth of teh dissenter's stock, which is to be arrived at after an appraisal of all the elements of value. Lucas v. Pembroke Water Co., 205 Va. 84, 135 S.E.2d 147 (1964).

Elements of "fair value."--Among the elements to be considered in arriving at the "fair value" or "fair cash value" of a dissenter's stock are its market value, net asset value, investment value, and earning capacity. Lucas v. Pembroke Water Co., 205 Va. 84, 135 S.E.2d 147 (1964).

The book value, or net asset value, of the stock is only one of the factors to be considered. Mere book value alone is not determinative. Lucas v. Pembroke Water Co., 205 Va. 84, 135 S.E.2d 147 (1964).

Excessive salary payments to officers and directors of a corporation are assets of the corporation to be considered along with other assets in fixing the value of the stock. Lucas v. Pembroke Water Co., 205 Va. 84, 135 S.E.2d 147 (1964).

"Fair cash value" means actual value.--Actual value of the shares of a stockholder dissenting to a consolidation or merger of a corporation is practically synonymous with "fair cash value" as those words were used in repealed ss 13-47. Adams v. United States Distrib. Corp., 184 Va. 134, 34 S.E.2d
244 (1945), cert. denied, 327 U.S. 788, 66 S. Ct. 807, 90 L. Ed. 1014 (1946).

The term "fair cash value" means the intrinsic worth of the dissenter's stock, which is to be arrived at after an appraisal of all the elements of value. Adams v. United States Distrib. Corp., 184 Va. 134, 34 S.E.2d 244 (1945), cert. denied, 327 U.S. 788, 66 S. Ct. 807, 90 L. Ed. 1014 (1946).

And not contractual value.--Dissenters may not recover the "contractual value" of their shares, the par value plus accrued cumulative dividends, as distinguished from the "fair cash value" or the "actual value." Adams v. United States Distrib. Corp., 184 Va. 134, 34 S.E.2d 244 (1945), cert. denied, 327 U.S. 788, 66 S. Ct. 807, 90 L. Ed. 1014 (1946).

Determination of fair value of dissenters' stock upon conflicting evidence is for the trial court. Lucas v. Pembroke Water Co., 205 Va. 84, 135 S.E.2d 147 (1964).

Amount of allowance of interest is left to discretion of trial court. Lucas v. Pembroke Water Co., 205 Va. 84, 135 S.E.2d 147 (1964).

ss.13.1-730. Right to Dissent.--A. A shareholder is entitled to dissent from, and obtain payment of the fair value of his shares in the event of, any of the following corporate actions:

Editor's note.--The cases below were decided under prior law.

Purpose of statutes.--The design of the statutes relating to the rights of a dissenting stockholder is to assure him that he will be fully compensated for the value of that of which he has been deprived by the merger, and no more. Adams v. United States Distrib. Corp., 184 Va. 134, 34 S.E.2d 244 (1945), cert. denied, 327 U.S. 788, 66 S. Ct. 807, 90 L. Ed. 1014 (1946).

Stockholder has election as to dissent.--Every stockholder of a merging corporation has an election either to dissent and secure in the prescribed manner the fair cash value of his stock or, if he fails to dissent, to be bound by the terms of the merger. Adams v. United States Distrib. Corp., 184 Va. 134, 34 S.E.2d 244 (1945), cert. denied, 327 U.S. 788, 66 S. Ct. 807, 90 L. Ed. 1014
(1946); Pittston Co. v. O'Hara, 191 Va. 886, 63 S.E.2d 34, appeal dismissed, 342 U.S. 803, 72 S. Ct. 38, 96 L. Ed. 608 (1951).

Exclusiveness of statutory remedy.--Unless a corporate merger be tainted with fraud or illegality, the dissenting stockholder must pursue the remedy prescribed by statute. Adams v. United States Distrib. Corp., 184 Va. 134, 34 S.E.2d 244 (1945), cert. denied, 327 U.S. 788, 66 S. Ct. 807, 90 L. Ed. 1014 (1946), wherein the court expressly refused to agree with Weiss v. Atkins, 52 F. Supp. 418 (S.D.N.Y. 1943), rev'd, 149 F.2d 193 (2nd Cir. 1945), and pointed out that Winfree v. Riverside Cotton Mills, 113 Va. 717, 75 S.E. 309
(1912), holding contra, was no longer applicable. See McGhee v. General Fin. Corp., 84 F. Supp. 24 (W.D. Va. 1949), holding that the remedy is available only in state courts.

The provisions of former law in regard to the valuation of the interest of dissatisfied members or stockholders in case of the merger of their corporation with another, were held to apply only in those cases in which the corporations seeking to merge had proceeded in all respects by authority of law. The provisions, therefore, were not exclusive of the right of dissatisfied members to contest the validity of an order of merger by the State Corporation Commission claimed to be destructive of their rights and interests, and utterly without warrant of law. Jones v. Rhea, 130 Va. 345, 107 S.E. 814 (1921).

It was held that the existence of a summary remedy of appraisal and payment under former ss 13-85 did not make the remedy at law adequate in such a manner as to defeat equity jurisdiction, and the existence of such remedy did not otherwise foreclose the plenary jurisdiction of a court of equity to grant an injunction in advance of action or to grant a money award on equitable principles after action. Craddock-Terry Co. v. Powell, 181 Va. 417, 25 S.E.2d
363 (1943); Pittston Co. v. O'Hara, 191 Va. 886, 63 S.E.2d 34, appeal dismissed, 342 U.S. 803, 72 S. Ct. 38, 96 L. Ed. 608 (1951).

Purchaser of stock is legally put upon notice that in event of merger his remedy will be provided by the statute. McGhee v. General Fin. Corp., 84 F. Supp. 24 (W.D. Va. 1949).

ss.13.1-731. Dissent by Nominees and Beneficial Owners.--A. A record shareholder may assert dissenters' rights as to fewer than all the shares registered in his name only if he dissents with respect to all shares beneficially owned by any one person and notifies the corporation in writing of the name and address of each person on whose behalf he asserts dissenters' rights. The rights of a partial dissenter under this subsection are determined as if the shares as to which he dissents and his other shares were registered in the names of different shareholders.

B. A beneficial shareholder may assert dissenters' rights as to shares held on his behalf only if:

1. He submits to the corporation the record shareholder's written consent to the dissent not later than the time the beneficial shareholder asserts dissenters' rights; and

2. He does so with respect to all shares of which he is the beneficial shareholder or over which he has power to direct the vote. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)

may be entitled to assert dissenters' rights under this article and be accompanied by a copy of this article.

B. If corporate action creating dissenters' rights under ss.13.1-730 is taken without a vote of shareholders, the corporation, during the ten-day period after the effectuation of such corporate action, shall notify in writing all record shareholders entitled to assert dissenters' rights that the action was taken and send them the dissenters' notice described in ss.13.1-734.(1985, c. 522.)

ss.13.1-733. Notice of Intent to Demand Payment.--A. If proposed corporate action creating dissenters' rights under ss.13.1-730 is submitted to a vote at a shareholders' meeting, a shareholder who wishes to assert dissenters' rights (i) shall deliver to the corporation before the vote is taken written notice of his intent to demand payment for his shares if the proposed action is effectuated and (ii) shall not vote such shares in favor of the proposed action.

B. A shareholder who does not satisfy the requirements of subsection A of this section is not entitled to payment for his shares under this article. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)

ss.13.1-734. Dissenters' Notice.--A. If proposed corporate action creating dissenters' rights under ss.13.1-730 is authorized at a shareholders' meeting, the corporation, during the ten-day period after the effectuation of such corporate action, shall deliver a dissenters' notice in writing to all shareholders who satisfied the requirements of ss.13.1-733.

B. The dissenters' notice shall:

1. State where the payment demand shall be sent and where and when certificates for certificated shares shall be deposited;

2. Inform holders of uncertificated shares to what extent transfer of the shares will be restricted after the payment demand is received;

3. Supply a form for demanding payment that includes the date of the first announcement to news media or to shareholders of the terms of the proposed corporate action and requires that the person asserting dissenters' rights certify whether or not he acquired beneficial ownership of the shares before or after that date;

4. Set a date by which the corporation must receive the payment demand, which date may not be fewer than thirty nor more than sixty days after the date of delivery of the dissenters' notice; and

5. Be accompanied by a copy of this article. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984,
c. 613; 1985, c. 522.)

ss.13.1-735. Duty to Demand Payment.--A. A shareholder sent a dissenters' notice described in ss.13.1-734 shall demand payment, certify that he acquired beneficial-ownership of the shares before or after the date required to be set forth in the dissenters' notice pursuant to paragraph 3 of subsection B of ss. 13.1-734, and, in the case of certificated shares, deposit his certificates in accordance with the terms of the notice.

B. The shareholder who deposits his shares pursuant to subsection A of this section retains all other rights of a shareholder except to the extent that these rights are canceled or modified by the taking of the proposed corporate action.

C. A shareholder who does not demand payment and deposits his share certificates where required each by the date set in the dissenters' notice, is not entitled to payment for his shares under this article. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)


ss.13.1-736 CODE OF VIRGINIA ss.13.1-739

ss.13.1-736. Share Restrictions.--A. The corporation may restrict the transfer of uncertificated shares from the date the demand for their payment is received.

B. The person for whom dissenters' rights are asserted as to uncertificated shares retains all other rights of a shareholder except to the extent that these rights are canceled or modified by the taking of the proposed corporate action. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968,
c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)

ss.13.1-737. Payment.--A. Except as provided in ss.13.1-738, within thirty days after receipt of a payment demand made pursuant to ss.13.1-735, the corporation shall pay the dissenter the amount the corporation estimates to be the fair value of his shares, plus accrued interest. The obligation of the corporation under this paragraph may be enforced (i) by the circuit court in the city or county where the corporation's principal office is located, or, if none in this Commonwealth, where its registered office is located or (ii) at the election of any dissenter residing or having its principal office in the Commonwealth, by the circuit court in the city or county where the dissenter resides or has its principal office. The court shall dispose of the complaint on an expedited basis.

B. The payment shall be accompanied by:

1. The corporation's balance sheet as of the end of a fiscal year ending not more than sixteen months before the effective date of the corporate action creating dissenters' rights, an income statement for that year, a statement of changes in shareholders' equity for that year, and the latest available interim financial statements, if any;

2. An explanation of how the corporation estimated the fair value of the shares and of how the interest was calculated;

3. A statement of the dissenters' right to demand payment under ss.13.1-739; and

4. A copy of this article. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)

ss.13.1-738. After-Acquired Shares.--A. A corporation may elect to withhold payment required by ss. 13.1-737 from a dissenter unless he was the beneficial owner of the shares on the date of the first publication by news media or the first announcement to shareholders generally, whichever is earlier, of the terms of the proposed corporate action, as set forth in the dissenters' notice.

B. To the extent the corporation elects to withhold payment under subsection A of this section, after taking the proposed corporate action, it shall estimate the fair value of the shares, plus accrued interest, and shall offer to pay this amount of each dissenter who agrees to accept it in full satisfaction of his demand. The corporation shall send with its offer an explanation of how it estimated the fair value of the shares and of how the interest was calculated, and a statement of the dissenter's right to demand payment under ss.13.1-739.

ss.13.1-740 CORPORATIONS ss.13.1-741

B. A dissenter waives his right to demand payment under this section unless he notifies the corporation of his demand in writing under subsection A of this section within thirty days after the corporation made or offered payment for his shares. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)

ss.13.1-740. Court Action.--A. If a demand for payment under ss.13.1-739 remains unsettled, the corporation shall commence a proceeding within sixty days after receiving the payment demand and petition the circuit court in the city or county described in subsection B of this section to determine the fair value of the shares and accrued interest. If the corporation does not commence the proceeding within the sixty-day period, it shall pay each dissenter whose demand remains unsettled the amount demanded.

B. The corporation shall commence the proceeding in the city or county where its principal office is located, or, if none in this Commonwealth, where its registered office is located. If the corporation is a foreign corporation without a registered office in this Commonwealth, it shall commence the proceeding in the city or county in this Commonwealth were the registered office of the domestic corporation merged with or whose shares were acquired by the foreign corporation was located.

C. The corporation shall make all dissenters, whether or not residents of this Commonwealth, whose demands remain unsettled parties to the proceeding as in an action against their shares and all parties shall be served with a copy of the petition. Nonresidents may be served by registered or certified mail or by publication as provided by law.

D. The corporation may join as a party to the proceeding any shareholder who claims to be a dissenter but who has not, in the opinion of the corporation, complied with the provisions of this article. If the court determines that such shareholder has not complied with the provisions of this article, he shall be dismissed as a party.

E. The jurisdiction of the court in which the proceeding is commenced under subsection B of this section is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend a decision on the question of fair value. The appraisers have the powers described in the order appointing them, or in any amendment to it. The dissenters are entitled to the same discovery rights as parties in other civil proceedings.

F. Each dissenter made a party to the proceeding is entitled to judgment (i) for the amount, if any, by which the court finds the fair value of his shares, plus interest, exceeds the amount paid by the corporation or (ii) for the fair value, plus accrued interest, of his after-acquired shares for which the corporation elected to withhold payment under ss.13.1-738. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)

ss.13.1-741. Court Costs and Counsel Fees.--A. The court in an appraisal proceeding commenced under ss.13.1-740 shall determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court. The court shall assess the costs against the corporation, except that the court may assess costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds the dissenters did not act in good faith in demanding payment under ss.13.1-739.

B. The court may also assess the reasonable fees and expenses of experts,


ss.13.1-742 CODE OF VIRGINIA ss.13.1-742

excluding those of counsel, for the respective parties, in amounts the court finds equitable:

1. Against the corporation and in favor of any or all dissenters if the court finds the corporation did not substantially comply with the requirements of ss. 13.1-732 through ss. 13.1-739; or

2. Against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed did not act in good faith with respect to the rights provided by this article.

C. If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated, the court may award to these counsel reasonable fees to be paid out of the amounts awarded the dissenters who were benefited.

D. In a proceeding commenced under subsection A of ss. 13.1-737 the court shall assess the costs against the corporation, except that the court may assess costs against all or some of the dissenters who are parties to the proceeding, in amounts the court finds equitable, to the extent the court finds that such parties did not act in good faith in instituting the proceeding. (Code 1950, S.S. 13-85, 13.1-75, 13.1-78; 1956, c. 428; 1968, c. 733; 1972, c. 425; 1975, c. 500; 1984, c. 613; 1985, c. 522.)


PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Article 10 of Chapter 9 of Title 13.1 of the Code of Virginia permits a Virginia corporation to indemnify any director or officer for reasonable expenses incurred in any legal proceeding in advance of final disposition of the proceeding, if the director or officer furnishes the corporation a written statement of his good faith belief that he has met the standard of conduct prescribed by the Code, and a determination is made by the board of directors that such standard has been met. In a proceeding by or in the right of the corporation, no indemnification shall be made in respect of any matter as to which an officer or director is adjudged to be liable to the corporation, unless the court in which the proceeding took place determines that, despite such liability, such person is reasonably entitled to indemnification in view of all the relevant circumstances. In any other proceeding, no indemnification shall be made if the director or officer is adjudged liable to the corporation on the basis that he improperly received personal benefit. Corporations are given the power to make any other or further indemnity, including advancement of expenses, to any director or officer that may be authorized by the articles of incorporation or any bylaw made by the shareholders, or any resolution adopted, before or after the event, by the shareholders, except an indemnity against willful misconduct or a knowing violation of the criminal law. Unless limited by its articles of incorporation, indemnification of a director or officer is mandatory when he entirely prevails in the defense of any proceeding to which he is a party because he is or was a director or officer.

The Articles of Incorporation of the Registrant contain provisions indemnifying the directors and officers of the Registrant to the full extent permitted by Virginia law. In addition, the Articles of Incorporation eliminate the personal liability of the Registrant's directors and officers to the Registrant or its shareholders for monetary damages in excess of one dollar to the full extent permitted by Virginia law.

Item 22. Undertakings

(a) Undertakings Required by Item 512 of Regulation S-K.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most

II-3


recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

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

The Registrant undertakes that every prospectus (i) that is filed pursuant to the paragraph immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

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

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

Exhibit 5

[TROUTMAN SANDERS MAYS & VALENTINE LLP LETTERHEAD]

January 26, 2001

Board of Directors
FNB Corporation
105 Arbor Drive
Christiansburg, Virginia 24068

Ladies and Gentlemen:

This letter is in reference to the amendment two to the Registration Statement on Form S-4 dated January 26, 2001, filed by FNB Corporation (the "Company") with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the "Registration Statement"). The Registration Statement relates to 431,094 shares of Common Stock, $5.00 par value per share (the "Shares"), which Shares are proposed to be offered to the shareholders of SWVA Bancshares, Inc., a Virginia unitary thrift holding company ("SWVA"), pursuant to an Agreement and Plan of Merger, dated as of August 7, 2000, by and between SWVA and the Company (collectively, the "Agreement").

We have examined such corporate proceedings, records and documents as we considered necessary for the purposes of this opinion. We have relied upon certificates of officers of the Company where we have deemed it necessary in connection with our opinion.

Based upon such examination, it is our opinion that the aforementioned Shares, when issued will be validly issued, fully paid and nonassessable under the laws of the Commonwealth of Virginia.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the caption "Legal Opinion" in the Proxy Statement forming a part of the Registration Statement.

Very truly yours,

/s/ TROUTMAN SANDERS MAYS & VALENTINE, L.L.P.


Exhibit 8

[Letterhead of Troutman Sanders Mays & Valentine LLP] January 26, 2001

FNB Corporation SWVA Bancshares, Inc. 105 Arbor Drive 302 Second Street, S.W. Christiansburg, Virginia 24068 Roanoke, Virginia 24011

Ladies/Gentlemen:

We have acted as special counsel to FNB Corporation, a Virginia corporation ("FNB"), in connection with the proposed merger (the "Merger") of SWVA Bancshares, Inc. ("SWVA") with and into FNB upon the terms and conditions set forth in the Agreement and Plan of Merger dated as of August 7, 2000, by and between FNB and SWVA (the "Agreement"). At your request, in connection with the filing of the Registration Statement on Form S-4 filed with the Securities and Exchange Commission in connection with the Merger (the "Registration Statement"), we are rendering our opinion concerning certain federal income tax consequences of the Merger.

For purposes of the opinion set forth below, we have relied, with the consent of FNB and the consent of SWVA, upon the accuracy and completeness of the statements and representations of fact (which statements and representations of fact we have neither investigated nor verified) contained, respectively, in the certificates of the officers of FNB and SWVA, and have assumed that such certificates will be complete and accurate as of the Effective Time. We have also relied upon the accuracy of the Registration Statement and the Proxy Statement/Prospectus included therein (together, the "Proxy Statement"). Any capitalized term used and not defined herein has the meaning given to it in the Proxy Statement or the appendices thereto (including the Agreement). We have also assumed that the transactions contemplated by the Agreement will be consummated in accordance therewith and as described in the Proxy Statement. All section references below are to the Internal Revenue Code of 1986.

Based upon and subject to the foregoing, we are of the opinion that:

(1) The Merger will constitute a "reorganization" within the meaning of Section 368(a)(1)(A).

(2) No gain or loss will be recognized by the shareholders of SWVA upon the receipt of solely FNB common stock in exchange for their SWVA stock (Section 354(a)(1)). However, a SWVA shareholder who receives FNB stock and cash in exchange for his SWVA common stock will recognize gain, if any, but not in excess of the amount of such cash (Section 356(a)(1)). If the exchange has the effect of the distribution of a dividend (determined with the application of Section 318(a)), the amount of gain


recognized that is not in excess of the SWVA shareholder's ratable share of accumulated earnings in profits will be treated as a dividend (Section
356(a)(2)). The determination of whether the exchange has the effect of the distribution of a dividend will be made in accordance with the principles set forth in Commissioner v. Clark, 109 S. Ct. 1455 (1989). The remainder, if any, of the gain recognized on such exchange will be treated as gain from the exchange of property. No loss will be recognized on the exchange (Section 356(c)).

(3) The basis of the FNB common stock received by a SWVA shareholder will be the same as the basis of the FNB stock that was exchanged therefor, decreased by the amount of any cash received and increased by the sum of
(i) the amount treated as a dividend and (ii) any gain recognized on the exchange (not including any portion of the gain that was treated as a dividend) (Section 358(a)(1)).

(4) The holding period of the FNB common stock received by a SWVA shareholder will include the period during which the SWVA stock surrendered in exchange therefor was held by the SWVA shareholder, provided that the SWVA stock surrendered was a capital asset in the hands of the SWVA shareholder on the Effective Date (Section 1223(1)).

(5) Where a SWVA shareholder receives solely cash in exchange for his SWVA common stock, such cash should be treated as received by that shareholder as a distribution in redemption of his SWVA common stock subject to the conditions and limitations of Section 302. Where, as a result of such distribution, a shareholder neither owns any stock of FNB directly, nor is deemed to own any such stock under the constructive ownership rules of Section 318(a), the redemption should be treated as a complete termination of interest within the meaning of Section 302(b)(3), and should be treated as a distribution full payment in exchange for the stock redeemed as provided in Section 302(a). Gain or loss should be realized and recognized to such shareholder measured by the difference between the redemption price and the adjusted basis of the SWVA shares surrendered as determined under Section 1011(Rev. Rul. 74-515, 1974-2 C.B. 118). Provided the SWVA stock is a capital asset in the hands of such shareholder, the gain or loss, if any, should constitute capital gain or loss subject to the provisions of subchapter P of Chapter 1 of the Internal Revenue Code.

(6) The payment of cash to SWVA shareholders in lieu of fractional share interests of FNB common stock will be treated as if the fractional shares were distributed as part of the exchange and then were redeemed by FNB. Such cash payments will be treated as distributions in full payment in exchange for the stock redeemed as provided in Section 302(a) (Rev. Rul. 66-365, 1966-2 C.B. 116 and Rev. Proc. 77-41-1977-2 C.B. 574).

(7) For purposes of (2) and (5) above, although there is no controlling precedent, the Merger and the additional merger of CNB Holdings, Inc. with and into FNB, when and if consummated, may be aggregated and treated as a single integrated transaction. In such case, the principles of Commissioner v. Clark, supra, and Section 302 would likely be applied by taking into account a shareholder's actual and constructive ownership of stock, if any, in SWVA, CNB and FNB both before and after the mergers.


This opinion represents our best legal judgment, but it has no binding effect or official status of any kind, and no assurance can be given that contrary positions may not be taken by the Internal Revenue Service or a court considering the issues. Also, future changes in federal income tax laws and the interpretation thereof can have retroactive effect.

Further, this opinion does not address the tax consequences that may be relevant to particular categories of shareholders subject to special treatment under the federal income tax laws, such as shareholders who are dealers or traders in securities or who mark securities to market, financial institutions, insurance companies, tax-exempt organizations, persons who are not United States citizens or resident aliens or domestic entities (partnerships or trusts), or are subject to the alternative minimum tax (to the extent that tax affects the tax consequences), or are subject to the golden parachute provisions of the Code (to the extent that tax effects the tax consequences), or shareholders who acquired SWVA common stock pursuant to employee stock options or otherwise as compensation, who do not hold their shares as capital assets, or who hold their shares as part of a "straddle" or "conversion transaction" or constructive sale or other integrated transaction.

We hereby consent to the filing of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement, and to the references to us under the caption "Material Federal Income Tax Consequences of the Merger" and elsewhere in the Proxy Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended.

[SWVA Letterhead]

Dear SWVA Bancshares, Inc. Shareholder,

This is an exciting time to be working and investing in the financial services industry. Our merger with FNB Corporation, the company that owns First National Bank in Christiansburg, is almost complete. The final step is yours - the election process.

The election process is explained in full detail in the attached Election Information and Instructions. It is extremely important that you read these instructions carefully, then return your completed Election Form and stock certificates by _______________, 2001.

As you make your election, it is important to note that you may not get all the stock or cash that you elected. Because the total number of shares and the amount of cash we can distribute to SWVA Bancshares' shareholders are limited by the terms of the merger. We believe that the overall result of this requirement will be to create greater value for you, our shareholders. Reducing the number of shares outstanding provides your company more flexibility and reduces the ultimate dilutive effect of the merger.

Again, I urge you to return your Election Form and certificates as soon as possible. Thank you for your investment as well as your overwhelming support of this merger.

Sincerely,

President and Chief Executive Officer

This letter contains forward-looking statements which are subject to risks and uncertainties. Discussion of factors that can cause actual results to differ materially from management's expectations, projections, forecasts and estimates is contained in the Company's Securities and Exchange Commission filings.

IRS Instructions for Completing Substitute Form W-9

Certification Instructions

You must cross out item (2) on the Substitute Form W-9 if you have been notified by the IRS that you are currently subject to backup withholding because of underreporting interest or dividends on your tax return. (Also see Signing The Certification under Specific Instructions).

(Section References are to the Internal Revenue Code.)

Purpose of Form

A person who is required to file an information return with IRS must obtain your correct taxpayer identification number (TIN) to report income paid to you. Use this Substitute Form W-9 to furnish your correct TIN to the requester (FNB Corporation), and when applicable, (1) to certify that the TIN you are furnishing is correct (or that you are waiting for a number to be issued), (2) to certify that you are not subject to backup withholding, and (3) to claim exemption from backup withholding if you are an exempt payee. Furnishing your correct TIN and making the appropriate certifications will prevent certain payments from being subject to the 31% backup withholding.

What is Backup Withholding

Persons making certain payments to you are required to withhold and pay to IRS 31% of such payments under certain conditions. This is called "backup withholding." Payments that could be subject to backup withholding include interest, dividends, broker and barter exchange transactions, rents, royalties, nonemployee compensation, and certain payments from fishing boat operators, but do not include real estate transactions.

If you give the requester your correct TIN, make the appropriate certifications, and report all your taxable interest and dividends on your tax return, your payments will not be subject to backup withholding. Payments you receive will be subject to backup withholding if:

(1) You do not furnish your TIN to the requester, or
(2) IRS notifies the requester that you furnished an incorrect TIN, or
(3) You are notified by IRS that you are subject to backup withholding because you failed to report all your interest and dividends on your tax return (for reportable interest and dividends only), or

(4) You fail to certify to the requester that you are not subject to backup withholding under (3) above (for reportable interest and dividend accounts opened after 1983 only), or

(5) You fail to certify your TIN. This applies only to reportable interest, dividend, broker, or barter exchange accounts opened after 1983, or broker accounts considered inactive in 1983.

Except as explained in (5) above, other reportable payments are subject to backup withholding only if (1) or (2) above applies.

Certain payees and payments are exempt from backup withholding and information reporting. See Payees and Payments Exempt from Backup Withholding and Exempt Payees and Payments under Specific Instructions, on page 14, if you are an exempt payee.

Instructions for Completing the Election Form

How to Obtain a TIN

If you do not have a TIN, you should apply for one immediately. To apply get Form SS-5, Application for a Social Security Number Card (for individuals) from your local office of the Social Security Administration, or Form SS-4, Application for Employer Identification Number (for businesses and all other entities), from your local Internal Revenue Service office.

To complete Form W-9 if you do not have a TIN, write "Applied For" in the space for the TIN in Part 1, sign and date the form and give it to the requester. Generally, you will then have 60 days to obtain a TIN and furnish it to the requester. If the requester does not receive your TIN within 60 days, backup withholding, if applicable, will begin and continue until you furnish your TIN to the requester. For reportable interest or dividend payments, the payer must exercise one of the following options concerning backup withholding during this 60-day period. Under option (1), a payer must backup withhold on any withdrawals you make from your account after 7 business days after the requester receives this form back from you. Under option (2), the payer must backup withhold on any reportable interest or dividend payments made to your account, regardless of whether you make any withdrawals. The backup withholding under option (2) must begin no later than 7 business days after the requester receives this form back. Under option (2), the payer is required to refund the amounts withheld if your certified TIN is received within the 60-day period and you were not subject to backup withholding during that period.

Note: Writing "Applied For" on the form means that you have already applied for a TIN OR that you intend to apply for one in the near future.
As soon as you receive your TIN, complete another Form W-9, include your TIN, sign and date the form, and give it to the requester.

Payees and Payments Exempt from Backup Withholding

The following is a list of payees exempt from backup withholding. For interest and dividends, all listed payees are exempt except item (2).

Penalties

If you fail to furnish your correct TIN to a requester, you are subject to a penalty of $50 for such failure unless your failure is due to a reasonable cause and not to willful neglect.

Civil Penalty for False Information with Respect to Withholding - If you make a false statement with no reasonable basis that results in no imposition of backup withholding, you are subject to a penalty of $500.

Criminal Penalty for Falsifying Information - Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Specific Instructions

Signing the Certification
