THIS AGREEMENT AND PLAN OF REORGANIZATION (the “Agreement”) is made and entered into as of August 24, 2014, between AMERICAN NATIONAL BANKSHARES INC., a Virginia corporation (“American”), and MAINSTREET BANKSHARES, INC., a Virginia corporation (“MainStreet”).

WHEREAS, the Boards of Directors of American and MainStreet have approved, and deem it advisable and in the best interests of their respective stockholders to consummate, the business combination transactions provided for herein, including the merger of MainStreet with and into American (the “Merger”);

WHEREAS, the Boards of Directors of American and MainStreet have each determined that the Merger is consistent with, and will further, their respective business strategies and goals; and

WHEREAS, it is the intention of the parties that, for federal income tax purposes, the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and that this Agreement shall constitute, and is adopted as, a “plan of reorganization” for purposes of Sections 354 and 361 of the Code.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE 1

1.1

The Merger.

Subject to the terms and conditions of this Agreement, at the Effective Date (as defined in Section 1.2), MainStreet will be merged with and into American pursuant to the Plan of Merger attached hereto as Exhibit 1.1 and made a part hereof (the “Plan of Merger”). The separate corporate existence of MainStreet thereupon shall cease, and American will be the surviving corporation in the Merger. The Merger will have the effect set forth in Section 13.1-721 of the Virginia Stock Corporation Act (the “VSCA”).

1.2

Effective Date; Closing.

(a) The Merger will become effective on the date and at the time shown on the Articles of Merger required to be filed with the office of the Virginia State Corporation Commission, as provided in Section 13.1-720 of the VSCA, effecting the Merger (the “Effective Date”). Subject to the satisfaction or waiver of the conditions set forth in Article 6, the parties will use their reasonable best efforts to cause the Effective Date to occur on January 1, 2015 or as soon as practicable thereafter and after all required regulatory and stockholder approvals to consummate

the Merger have been received. At or after the Closing Date (as defined below), American and MainStreet will execute and deliver Articles of Merger containing the Plan of Merger to the Virginia State Corporation Commission.

(b) Subject to the terms and conditions of this Agreement, the closing of the Merger will take place at 10:00 a.m. Eastern Time at the corporate office headquarters of American on a date mutually agreed to by the parties and which shall be held at or before the Effective Date (the “Closing Date”). All documents required by this Agreement to be delivered at or before the Effective Date will be exchanged by the parties on the Closing Date.

1.3

Subsidiary Bank Merger.

At the Effective Date or as soon thereafter as reasonably practicable, Franklin Community Bank, National Association, the wholly-owned national banking association subsidiary of MainStreet (“Franklin Community Bank”), shall be merged with and into American National Bank and Trust Company (“American National Bank”), the wholly-owned national banking association subsidiary of American (the “Subsidiary Bank Merger”), pursuant to the Subsidiary Bank Agreement and Plan of Merger, the form of which is attached hereto as Exhibit 1.3. As soon as practicable after the approval of this Agreement by the Boards of Directors of American and MainStreet, and no later than the date of this Agreement, each of American, American National Bank, MainStreet and Franklin Community Bank, respectively, shall take all actions necessary to approve and adopt the Subsidiary Bank Agreement and Plan of Merger, including effecting the necessary stockholder and board of director approvals, all of which shall be conditioned on the consummation of the Merger. Prior to the Effective Date, such parties shall take all actions necessary to approve and adopt any and all other agreements and documents to effect the Subsidiary Bank Merger.

1.4

Articles of Incorporation and Bylaws of American.

The Articles of Incorporation of American as in effect immediately prior to the Effective Date will be the Articles of Incorporation of American at and after the Effective Date until thereafter amended in accordance with applicable law. The Bylaws of American as in effect immediately prior to the Effective Date will be the Bylaws of American at and after the Effective Date until thereafter amended in accordance with applicable law.

ARTICLE 2

Merger Consideration; Exchange Procedures

2.1

Conversion of Shares.

At the Effective Date, by virtue of the Merger and without any action on the part of American or MainStreet or their respective stockholders:

(a) Each share of common stock, par value $1.00 per share, of American (“American Common Stock”), that is issued and outstanding immediately before the Effective Date shall remain issued and outstanding and shall remain unchanged by the Merger.

(b) Each share of common stock, no par value, of MainStreet (“MainStreet Common Stock”), that is issued and outstanding immediately before the Effective Date (other than the Dissenting Shares as defined in Section 2.8) will be converted into and exchanged for the right to receive (i) 0.482 shares (the “Exchange Ratio”) of American Common Stock (the “Stock Consideration”) and (ii) a cash sum of $3.46 (the “Cash Consideration” and, together with the Stock Consideration, the “Merger Consideration”).

(c) All shares of MainStreet Common Stock converted pursuant to this Section 2.1 shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist as of the Effective Date.

(d) Each certificate previously representing shares of MainStreet Common Stock (a “MainStreet Common Certificate”) shall cease to represent any rights except the right to receive with respect to each underlying share of MainStreet Common Stock (i) the Merger Consideration upon the surrender of such MainStreet Common Certificate in accordance with Section 2.2, and (ii) any dividends or distributions or cash in lieu of fractional shares which the holder thereof has the right to receive pursuant to Sections 2.4 and 2.6.

(e) Each share of MainStreet Common Stock held by either party and each share of American Common Stock held by MainStreet or any of the MainStreet Subsidiaries (as defined herein) prior to the Effective Date (in each case other than in a fiduciary or agency capacity or on behalf of third parties as a result of debts previously contracted) shall be cancelled and retired and shall cease to exist at the Effective Date and no consideration shall be issued in exchange therefor; provided, that such shares of American Common Stock shall resume the status of authorized and unissued shares of American Common Stock.

2.2

Exchange Procedures.

(a) On or before Closing Date, American shall deposit, or shall cause to be deposited, with its transfer agent or such other transfer agent or depository or trust institution of recognized standing approved by American (in such capacity, the “Exchange Agent”), for the benefit of the holders of the MainStreet Common Certificates, (i) certificates representing the shares of American Common Stock issuable pursuant to this Article 2, and (ii) cash equal to the aggregate amount of the Cash Consideration issuable pursuant to this Article 2, together with any dividends or distributions with respect thereto and any cash to be paid in lieu of fractional shares without any interest thereon (the “Exchange Fund”), in exchange for certificates representing outstanding shares of MainStreet Common Stock.

(b) As promptly as practicable after the Effective Date, American shall cause the Exchange Agent to send to each former stockholder of record of MainStreet immediately before the Effective Date transmittal materials for use in exchanging such stockholder’s MainStreet Common Certificates for the Merger Consideration, as provided for herein.

(c) American shall cause the Merger Consideration into which shares of MainStreet Common Stock are converted at the Effective Date, and dividends or distributions which a

MainStreet stockholder shall be entitled to receive and any cash to be paid in lieu of fractional shares, to be issued and paid to such MainStreet stockholder upon delivery to the Exchange Agent of MainStreet Common Certificates representing such shares of MainStreet Common Stock, together with the transmittal materials duly executed and completed in accordance with the instructions thereto. No interest will accrue or be paid on any such cash to be paid pursuant to Sections 2.4 or 2.6.

(d) Any MainStreet stockholder whose MainStreet Common Certificates have been lost, destroyed, stolen or are otherwise missing shall be entitled to the Merger Consideration, dividends or distributions, and cash in lieu of fractional shares to which such stockholder shall be entitled upon compliance with reasonable conditions imposed by American pursuant to applicable law and as required in accordance with American’s standard policy (including the requirement that the shareholder furnish a surety bond or other customary indemnity).

(e) Any portion of the Exchange Fund that remains unclaimed by the stockholders of MainStreet for twelve (12) months after the Effective Date shall be returned to American (together with any earnings in respect thereof). Any stockholders of MainStreet who have not complied with this Article 2 shall thereafter be entitled to look only to American, and only as a general creditor thereof, for payment of the consideration deliverable in respect of each share of MainStreet Common Stock such stockholder holds as determined pursuant to this Agreement, without any interest thereon.

(f) None of the Exchange Agent, either of the parties hereto or any of the American Subsidiaries (as defined herein) or the MainStreet Subsidiaries (as defined herein) shall be liable to any stockholder of MainStreet for any amount of property delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

2.3

MainStreet Stock Options.

(a) At the Effective Date, each option to purchase shares of MainStreet Common Stock (a “MainStreet Stock Option”) granted under an equity or equity-based compensation plan of MainStreet (a “MainStreet Stock Plan”) or otherwise granted shall vest and shall be converted into an option (each, a “Replacement Option”) to acquire, on the same terms and conditions as were applicable under such MainStreet Stock Option (except as provided otherwise in this Section 2.3(a)), the number of shares of American Common Stock equal to the product of (i) the number of shares of MainStreet Common Stock subject to the MainStreet Stock Option multiplied by (ii) 0.643 (the “Option Exchange Ratio”). Such product shall be rounded down to the nearest whole number. The exercise price per share (rounded up to the next whole cent) of each Replacement Option shall equal (y) the exercise price per share of shares of MainStreet Common Stock that were purchasable pursuant to such MainStreet Stock Option divided by (z) the Option Exchange Ratio. Notwithstanding the foregoing, each MainStreet Stock Option that is intended to be an “incentive stock option” (as defined in Section 422 of the Code) shall be adjusted if necessary in accordance with the requirements of Section 424 of the Code and all other options shall be adjusted if necessary in a manner that maintains the options exemption from Section 409A of the Code. At the Effective Date, American shall assume the MainStreet Stock Plans; provided that such assumption shall only be with respect to the Replacement Options and American shall have no obligation to make any additional grants or awards under the MainStreet Stock Plans.

(b) As soon as practicable after the Effective Date, American will deliver to the holders of Replacement Options any required notices setting forth such holders’ rights pursuant to the respective MainStreet Stock Plan and award documents and stating that such Replacement Options have been issued by American and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 2.3 after giving effect to the Merger and the terms of the MainStreet Stock Plan).

2.4

No Fractional Shares.

Each holder of shares of MainStreet Common Stock exchanged pursuant to the Merger which would otherwise have been entitled to receive a fraction of a share of American Common Stock shall receive, in lieu thereof, cash (without interest and rounded to the nearest cent) in an amount equal to such fractional part of a share of American Common Stock multiplied by the closing sale price of American Common Stock on the NASDAQ Global Select Market for the trading day immediately preceding (but not including) the Effective Date.

2.5

Anti-Dilution.

In the event American changes (or establishes a record date for changing) the number of shares of American Common Stock issued and outstanding before the Effective Date as a result of a stock split, stock dividend, recapitalization, reclassification, reorganization or similar transaction, appropriate and proportional adjustments will be made to the Exchange Ratio.

2.6

Dividends.

No dividend or other distribution payable to the holders of record of MainStreet Common Stock at, or as of, any time after the Effective Date will be paid to the holder of any MainStreet Common Certificate until such holder physically surrenders such certificate (or furnishes a surety bond or a customary indemnity that such certificate is lost, destroyed, stolen or otherwise missing as provided in Section 2.2(d)) for exchange as provided in Section 2.2 of this Agreement, promptly after which time all such dividends or distributions will be paid (without interest).

2.7

Withholding Rights.

The Exchange Agent will be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any person such amounts, if any, as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax (as defined herein) law. To the extent that amounts are so withheld and remitted to the appropriate Governmental Authority (as defined herein) by the Exchange Agent, such amounts withheld will be treated for all purposes of this Agreement as having been paid to such person in respect of which such deduction and withholding was made by the Exchange Agent.

2.8

Dissenting Shares.

Any holder of shares of MainStreet Common Stock who perfects such holder’s appraisal rights in accordance with and as contemplated by Sections 13.1-729 through 13.1-741.1 of the VSCA shall be entitled to receive from American, in lieu of the Merger Consideration, the value of such shares as to which appraisal rights have been perfected in cash as determined pursuant to the VSCA; provided, that no such payment shall be made to any dissenting stockholder unless and until such dissenting stockholder has complied with all applicable provisions of the VSCA, and surrendered to MainStreet the certificate or certificates representing the shares for which payment is being made (the “Dissenting Shares”). In the event that after the Effective Date a dissenting stockholder of MainStreet fails to perfect, or effectively withdraws or loses, such holder’s right to appraisal of and payment for such holder’s shares, American shall issue and deliver the consideration to which such holder of shares of MainStreet Common Stock is entitled under this Article 2 (without interest) upon surrender by such holder of the MainStreet Common Certificate representing such shares.

ARTICLE 3

Representations and Warranties

3.1

Disclosure Schedule.

Prior to the date of this Agreement, MainStreet has delivered to American a schedule (its “Disclosure Schedule”) setting forth, among other things, items the disclosure of which is necessary or appropriate either in response to an express disclosure requirement contained in a provision hereof or as an exception to one or more of MainStreet’s representations or warranties contained in Section 3.3 or to one or more of its covenants or agreements contained in Articles 4 or 5; provided that, (i) no such item is required to be set forth in MainStreet’s Disclosure Schedule as an exception to any representation or warranty of MainStreet if its absence would not result in the related representation or warranty being deemed untrue or incorrect under the standard established by Section 3.2, and (ii) the mere inclusion of an item in MainStreet’s Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by MainStreet that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect (as defined herein) with respect to MainStreet.

3.2

Standard.

(a) No representation or warranty of American or MainStreet contained in Article 3 (other than the representations and warranties contained in (i) Sections 3.3(c)(i) and 3.3(u) for MainStreet and Section 3.4(c)(i) for American, which shall be true in all material respects to it, and (ii) Sections 3.3(c)(ii)(A), 3.3(d), 3.3(g)(ii) and 3.3(p) for MainStreet and Sections 3.4(c)(ii)(A), 3.4(d) and 3.4(g)(ii) for American, which shall be true and correct in all respects) will be deemed untrue or incorrect, and no party will be deemed to have breached a representation or warranty, as a consequence of the existence or absence of any fact, event or circumstance unless such fact, event or circumstance, individually or taken together with all

other facts, events or circumstances inconsistent with any representation or warranty contained in Section 3.3 or Section 3.4, has had or is reasonably likely to have a Material Adverse Effect on such party.

(b) The term “Material Adverse Effect,” as used with respect to a party, means an event, change, effect or occurrence which, individually or together with any other event, change, effect or occurrence, (i) is materially adverse to the business, properties, financial condition or results of operations of such party and its subsidiaries (meaning the “MainStreet Subsidiaries” as defined in Section 3.3(b) or the “American Subsidiaries” as defined in Section 3.4(b), as the case may be), taken as a whole, or (ii) materially impairs the ability of such party to perform its obligations under this Agreement or to consummate the Merger and the other transactions contemplated by this Agreement on a timely basis; provided that a Material Adverse Effect shall not be deemed to include the impact of (A) changes after the date of this Agreement in laws or regulations generally affecting the banking and bank holding company businesses and the interpretation of such laws and regulations by courts or governmental authorities, (B) changes after the date of this Agreement in generally accepted accounting principles or regulatory accounting requirements generally affecting the banking and bank holding company businesses, (C) changes or events after the date of this Agreement generally affecting the banking and bank holding company businesses, including changes in prevailing interest rates, and not specifically relating to American, the American Subsidiaries, MainStreet or the MainStreet Subsidiaries, (D) the effects of the actions expressly permitted or required by this Agreement or that are taken with the prior informed consent of the other party in contemplation of the transactions contemplated hereby, (E) the public disclosure of this Agreement and the transactions contemplated hereby, (F) a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections or internal financial forecasts, but not including the underlying causes thereof, and (G) any outbreak or escalation of major hostilities or acts of terrorism which involves the United States; except, with respect to clauses (A), (B), (C) or (G), to the extent that the effects of such change are materially disproportionately adverse to the business, properties, financial condition or results of operations such party hereto and its subsidiaries, taken as a whole, as compared to other comparable companies in the industry in which such party and its subsidiaries operate.

(c) The term “Knowledge” when used with respect to a party means (i) the actual knowledge and belief of such party’s executive officers, and (ii) the knowledge that a reasonably prudent executive officer should have if such person duly performed his or her duties as an executive officer of such party. For the purpose of the term Knowledge, “executive officer” shall mean (y) with respect to American, its Executive Chairman, its President and Chief Executive Officer and its Senior Vice President and Chief Financial Officer, and (z) with respect to MainStreet, its President and Chief Executive Officer, its Executive Vice President and Senior Lender, its Senior Vice President and Chief Financial Officer and its Senior Vice President and Operations Officer.

3.3

Representations and Warranties of MainStreet.

Subject to and giving effect to Sections 3.1 and 3.2 and except as set forth in its Disclosure Schedule, MainStreet hereby represents and warrants to American as follows:

(a) Organization, Standing and Power. MainStreet is a Virginia corporation duly organized, validly existing and in good standing under the laws of Virginia. MainStreet has the corporate power and authority to carry on its business as now conducted and to own and operate its assets, properties and business. MainStreet is duly registered as a bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHCA”). Franklin Community Bank, a wholly-owned subsidiary of MainStreet, is a national bank duly organized, validly existing and in good standing under the laws of the United States of America, and has all requisite corporate power and authority to carry on a commercial banking business as now being conducted and to own and operate its assets, properties and business. Franklin Community Bank’s deposits are insured by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”) to the maximum extent permitted by law. True and complete copies of the articles of incorporation, bylaws or other similar governing instruments (“Organizational Documents”) of MainStreet and Franklin Community Bank, in each case as amended to the date hereof and as in full force and effect as of the date hereof, are set forth in Section 3.3(a) of the MainStreet Disclosure Schedule.

(b) Subsidiaries. MainStreet does not own, directly or indirectly, five percent (5%) or more of the outstanding capital stock or other equity interests of any corporation, bank or other organization actively engaged in business except as set forth in Section 3.3(b) in the MainStreet Disclosure Schedule (each individually a “MainStreet Subsidiary” and collectively the “MainStreet Subsidiaries”). Each MainStreet Subsidiary (i) is a duly organized bank, corporation, limited liability company or statutory trust, validly existing and in good standing under applicable laws, (ii) has full corporate power and authority to carry on its business as now conducted and (iii) is duly qualified to do business in the states where its ownership or leasing of property or the conduct of its business requires such qualification and where the failure to so qualify would have a Material Adverse Effect on MainStreet on a consolidated basis. The outstanding shares of capital stock or equity interests of each MainStreet Subsidiary have been duly authorized and are validly issued and outstanding, fully paid and nonassessable and all such shares are directly or indirectly owned by MainStreet free and clear of all liens, claims and encumbrances or preemptive rights of any person. No rights are authorized, issued or outstanding with respect to the capital stock or equity interests of any MainStreet Subsidiary and there are no agreements, understandings or commitments relating to the right of MainStreet to vote or to dispose of the capital stock or equity interests of any MainStreet Subsidiary. A true and complete list of each direct and indirect MainStreet Subsidiary as of the date hereof is set forth in Section 3.3(b) of the MainStreet Disclosure Schedule that shows the jurisdiction of organization of each MainStreet Subsidiary, its form of organization (corporate, partnership, joint venture), and lists the owner(s) and percentage ownership (direct or indirect) of each MainStreet Subsidiary.

(i) MainStreet has the corporate power and authority to execute, deliver and perform its obligations under this Agreement, and to consummate the transactions contemplated hereby. The execution, delivery and performance of this Agreement by MainStreet, and the consummation of the transactions contemplated hereby, have been duly and validly authorized by all necessary corporate action on the part of MainStreet, subject only to the receipt of the approval of this Agreement and the Plan of Merger by the holders of more than two-thirds of the outstanding shares of MainStreet Common Stock

(the “MainStreet Stockholder Approval”). This Agreement is a valid and legally binding obligation of MainStreet, enforceable in accordance with its terms (except as enforceability may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws affecting the enforcement of rights of creditors or by general principles of equity).

(ii) Neither the execution and delivery of this Agreement by MainStreet, nor the consummation by MainStreet of the transactions contemplated hereby, nor compliance by MainStreet with any of the provisions hereof will: (A) conflict with or result in a breach of any provision of the Organizational Documents of MainStreet or Franklin Community Bank; (B) constitute or result in the breach of any term, condition or provision of, or constitute a 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 asset of MainStreet or any MainStreet Subsidiary pursuant to any (1) note, bond, mortgage, indenture, or (2) any material license, agreement or other instrument or obligation, to which MainStreet or any MainStreet Subsidiary is a party or by which MainStreet or any MainStreet Subsidiary or any of their properties or assets may be bound; or (C) subject to the receipt of all required regulatory and stockholder approvals, violate any order, writ, injunction, decree, statute, rule or regulation applicable to MainStreet or any MainStreet Subsidiary.

(iii) As of the date hereof, MainStreet is not aware of any reason why the necessary regulatory approvals and consents will not be received in order to permit consummation of the Merger.

(d) MainStreet Capital Stock. The authorized capital stock of MainStreet consists of 10,000,000 shares of preferred stock, no par value, of which no shares are issued and outstanding, and 10,000,000 shares of common stock, no par value, of which 1,713,375 shares are issued and outstanding as of the date of this Agreement. All outstanding shares of MainStreet Common Stock have been duly authorized and validly issued, are fully paid and nonassessable and have not been issued in violation of the preemptive rights of any person. As of the date of this Agreement, 67,023 shares of MainStreet Common Stock are subject to MainStreet Stock Options granted under a MainStreet Stock Plan.

All Taxes owed by American or any of its Subsidiaries have been paid, are reflected as a liability in its SEC Reports or Bank Reports, or are being contested in good faith as set forth in its Disclosure Schedule. No tax return or report filed by American or any of the American Subsidiaries is under examination by any Governmental Authority or the subject of any administrative or judicial proceeding, and no unpaid tax deficiency has been asserted against American or any of the American Subsidiaries by any Governmental Authority. American is not aware of any reason why the Merger will fail to qualify as a reorganization under Section 368(a) of the Code.

(k) Employee Benefit Plans.

(i) All of the American Benefit Plans (as defined herein) are in compliance in all material respects with applicable laws and regulations, and American and American National Bank have administered such benefit plans in accordance with applicable laws and regulations in all material respects. For the purposes of this Agreement, a “American Benefit Plan” means an employee benefit plan and program of American and the American Subsidiaries, including without limitation: (A) all retirement, savings and other pension plans; (B) all health, severance, insurance, disability and other employee welfare

plans; and (C) all employment, vacation and other similar plans, all bonus, stock option, stock purchase, incentive, deferred compensation, supplemental retirement, severance and other employee and director benefit plans, programs or arrangements, and all employment or compensation arrangements, in each case for the benefit of or relating to its current and former employees and directors (collectively, the “American Benefit Plans”).

(ii) Each American Benefit Plan that is intended to be qualified under Section 401(a) of the Code has been determined by the Internal Revenue Service to be so qualified, as reflected in a current favorable determination letter (based on Internal Revenue Service permitted determination request procedures), or a filing for the same has been made with the Internal Revenue Service seeking such a determination letter and that request is still awaiting decision by the Internal Revenue Service (based on Internal Revenue Service permitted determination request procedures). Nothing has occurred since the date of any such determination that is reasonably likely to affect adversely such qualification or exemption, or result in the imposition of excise taxes or income taxes on unrelated business income under the Code or ERISA with respect to any tax-qualified plan. There have been no “terminations,” “partial terminations” or “discontinuances of contributions,” as such terms are used in Section 411 of the Code and the regulations thereunder, to any tax-qualified plan during the preceding five years without notice to and approval by the Internal Revenue Service and payment of all obligations and liabilities attributable to such tax-qualified plans.

(l) Insurance. American and the American Subsidiaries are insured with reputable insurers against such risks and in such amounts as management of American reasonably has determined to be prudent in accordance with industry practices. Since December 31, 2013, neither American nor any of the American Subsidiaries has received any notice of a premium increase or cancellation or a failure to renew with respect to any insurance policy or bond or, within the last three (3) calendar years, and since January 1, 2014, has been refused any insurance coverage sought or applied for, and American has no reason to believe that existing insurance coverage cannot be renewed as and when the same shall expire upon terms and conditions as favorable as those presently in effect, other than possible increases in premiums or unavailability of coverage that do not result from any extraordinary loss experience on the part of American or the American Subsidiaries.

(m) Allowance for Loan Losses. The Loan Loss Allowance shown by American in its SEC Reports or Bank Reports as of June 30, 2014 was, and the Loan Loss Allowance to be shown in its SEC Reports or Bank Reports as of any date subsequent to the date of this Agreement will be, as of such dates, adequate to provide for possible losses, net of recoveries relating to loans previously charged off, in respect of loans outstanding (including letter of credit or commitments to make loans or extend credit). The Loan Loss Allowance has been established in accordance with GAAP, and applicable regulatory requirements and guidelines.

(n) Environmental Matters. American and each of the American Subsidiaries are in compliance with all Environmental Laws. Neither American nor any of the American Subsidiaries has received any communication alleging that American or such American Subsidiary is not in

such compliance, and, to its Knowledge, there are no present circumstances that would prevent or interfere with the continuation of such compliance. To the Knowledge of American, there are no past or present actions, activities, circumstances, events, or incidents that could reasonably form the bases 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 against American or any of the American Subsidiaries or against any person or entity whose liability for any Environmental Claim American or an American Subsidiary has or may have retained contractually or by operation of law.

(o) Books and Records. The books and records of American and those of the American Subsidiaries have been fully, properly and accurately maintained in all material respects, and there are no material inaccuracies or discrepancies of any kind contained or reflected therein.

5.1

Reasonable Best Efforts.

Subject to the terms and conditions of this Agreement, the parties hereto will use their reasonable best efforts to take, or cause to be taken, in good faith all actions, and to do, or cause to be done, all things necessary or desirable, or advisable under applicable laws, so as to permit consummation of the Merger as promptly as practicable and shall cooperate fully with the other party hereto to that end.

5.2

Access to Information; Notice of Certain Matters; Confidentiality.

(a) Upon reasonable notice and subject to applicable laws regarding the disclosure or exchange of information, MainStreet shall permit American to make or cause to be made such investigation of MainStreet’s operational, financial and legal condition as American reasonably requests; provided, that such investigation shall be reasonably related to the Merger and shall not interfere unreasonably with normal operations. No investigation, in and of itself, by American shall affect the representations and warranties of MainStreet. American will receive notice of all meetings of the MainStreet and Franklin Community Bank Boards of Directors and any committees thereof, and of any management committees (in all cases, at least as timely as all MainStreet and Franklin Community Bank representatives to such meetings are provided notice). An executive officer of American will be permitted to attend all meetings of the MainStreet and Franklin Community Bank Boards of Directors and committees of the Boards of Directors (except for the portions of such meetings that are executive sessions, relate to the Merger or a

Superior Proposal (as defined herein), or as may be necessary or appropriate in order to preserve attorney-client privilege, as deemed by such boards) and such meetings of management of MainStreet and Franklin Community Bank that American wishes to attend. MainStreet shall also provide to a designated executive officer of American all written agendas and meeting or written consent materials provided to the directors of MainStreet in connection with Board and committee meetings, subject to applicable laws regarding the disclosure or exchange of information. Any such representative of American may be required to enter into an appropriate confidentiality and “no trade” agreement satisfactory to MainStreet prior to attending any such meetings.

(b) During the period from the date of this Agreement to the Effective Date, MainStreet shall, upon the request of American, cause one or more of its designated executive officers to confer on a monthly or more frequent basis with American regarding MainStreet’s financial condition, operations and business and matters relating to the completion of the Merger. As soon as reasonably available, but in no event more than thirty (30) days after the end of each calendar quarter ending after the date of this Agreement (other than the last quarter of each fiscal year ending December ▇▇), ▇▇▇▇▇▇▇▇▇▇ will deliver to American its unaudited balance sheet and statements of income, stockholders’ equity and cash flows, without related notes, for such quarter prepared in accordance with GAAP. As soon as reasonably available, but in no event more than sixty (60) days after the end of each fiscal year, MainStreet will deliver to American its unaudited balance sheet and statements of income, shareholders’ equity and cash flows, without related notes, for such year prepared in accordance with GAAP. Within fifteen (15) days after the end of each month, MainStreet will deliver to American (i) such loan reports as American may reasonably request, and (ii) such other financial data as American may reasonably request. The financial statements required to be delivered by this Section 5.2(b) may be consolidated.

(c) Each party hereto will give prompt notice to the other party (and subsequently keep the other party informed on a current basis) upon its becoming aware of the occurrence or existence of any fact, event or circumstance known that (i) is reasonably likely to result in any Material Adverse Effect with respect to it, or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein.

(d) Each party hereto shall, and shall use its reasonable best efforts to cause each of its directors, officers, attorneys and advisors, to maintain the confidentiality of, and not use to the detriment of the other party, all information of the other party obtained prior to the date of this Agreement or pursuant to this Section 5.2 that is not otherwise publicly disclosed by the other party, unless such information is required to be included in any filing required by law or in an application for any Regulatory Approval required for the consummation of the transactions contemplated hereby, such undertaking with respect to confidentiality to survive any termination of this Agreement. In the case of information that a party believes is necessary in making any such filing or obtaining any such Regulatory Approval, that party will provide the other party a reasonable opportunity to review any such filing or any application for such Regulatory Approval before it is filed sufficient for it to comment on and object to the content of such filing or application. If this Agreement is terminated, each party shall promptly return to the furnishing party or, at the request of the furnishing party, destroy and certify the destruction of all confidential information received from the other party.

5.3

Stockholder Approval.

MainStreet shall call a meeting of its stockholders for the purpose of obtaining the MainStreet Stockholders Approval and shall use its reasonable best efforts to cause such meeting to occur as soon as reasonably practicable (such meeting and any adjournment or postponement thereof, the “MainStreet Stockholders Meeting”). In connection with that meeting, the Board of Directors of MainStreet shall support and recommend approval of this Agreement and the transactions contemplated hereby and shall use its reasonable best efforts to obtain the MainStreet Stockholders Approval unless the Board of Directors of MainStreet has received and recommended (or submitted to stockholders) a Superior Proposal in accordance with Section 5.5.

5.4

Registration Statement; Proxy Statement; SEC Filings.

(a) Each party will cooperate with the other party, and their representatives, in the preparation of a registration statement on Form S-4, including any pre-effective or post-effective amendments or supplements thereto (the “Registration Statement”), to be filed by American with the SEC in connection with the MainStreet Stockholders Meeting, and the parties will prepare a proxy statement and prospectus and other proxy solicitation materials of MainStreet constituting a part thereof (the “Proxy Statement”). Neither the Proxy Statement nor the Registration Statement shall be filed, and, prior to the earlier of the Effective Date or the termination of this Agreement, no amendment or supplement to the Proxy Statement or the Registration Statement shall be filed, by American without consultation with MainStreet and its counsel. American will use its reasonable best efforts, in which MainStreet will reasonably cooperate as necessary, to file the Registration Statement, including the Proxy Statement in preliminary form, with the SEC as promptly as reasonably practicable and to cause the Registration Statement to be declared effective under the Securities Act, as promptly as reasonably practicable after the filing thereof, and MainStreet shall thereafter mail or deliver the Proxy Statement to its stockholders.

(b) Each party agrees, as to itself and its subsidiaries, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (i) the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (ii) the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to the MainStreet stockholders and at the time of the MainStreet Stockholders Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which such statement was made, not misleading. Each party further agrees that if it becomes aware that any information furnished by it that would cause any of the statements in the Proxy Statement or the Registration Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take appropriate steps to correct the Proxy Statement or the Registration Statement.

No Other Acquisition Proposals.

(a) MainStreet agrees that it will not, and will cause the MainStreet Subsidiaries and MainStreet’s and the MainStreet Subsidiaries’ officers, directors, employees, agents and representatives (including any financial advisor, attorney or accountant retained by MainStreet or any of the MainStreet Subsidiaries) not to, directly or indirectly, (i) initiate, solicit or encourage inquiries or proposals with respect to, (ii) furnish any confidential or nonpublic information relating to, or (iii) engage or participate in any negotiations or discussions concerning, an Acquisition Proposal (as defined herein).

(b) Notwithstanding the foregoing, nothing contained in this Section 5.5 shall prohibit MainStreet, prior to its meeting of stockholders to be held pursuant to Section 5.3 and subject to compliance with the other terms of this Section 5.5, from furnishing nonpublic information to, or entering into discussions or negotiations with, any person or entity that makes an unsolicited, bona fide written Acquisition Proposal with respect to MainStreet (that did not result from a breach of this Section 5.5) if, and only to the extent that (i) the MainStreet Board of Directors concludes in good faith, after consultation with and based upon the written advice of outside legal counsel and its financial advisors, that the failure to take such actions would be more likely than not to result in a violation of its fiduciary duties to stockholders under applicable law, (ii) before taking such actions, MainStreet receives from such person or entity an executed confidentiality agreement on terms no less favorable to it than the Confidentiality Agreement, dated May 29, 2014, between American and MainStreet (the “Confidentiality Agreement”), which confidentiality agreement shall not provide such person or entity with any exclusive right to negotiate with MainStreet, and (iii) the MainStreet Board of Directors concludes in good faith, after consultation with its outside legal counsel and financial advisors, that the Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal (as defined below). MainStreet shall immediately (within twenty-four (24) hours) notify American orally and in writing of MainStreet’s receipt of any such proposal or inquiry, the material terms and conditions thereof, the identity of the person making such proposal or inquiry, and will keep American apprised of any related developments, discussions and negotiations on a current basis, including by providing a copy of all material documentation or correspondence relating thereto.

(c) For purposes of this Agreement, an “Acquisition Proposal” means, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third party indication of interest in, any of the following transactions involving MainStreet or Franklin Community Bank: (i) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction; (ii) any acquisition or purchase, direct or indirect, of ten percent (10%) or more of the consolidated assets of MainStreet or ten percent (10%) or more of any class of equity or voting securities of MainStreet or the MainStreet Subsidiaries whose assets, individually or in the aggregate, constitute more than ten percent (10%) of the consolidated assets of MainStreet; or (iii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning ten percent (10%) or more of any class of equity or voting securities of MainStreet or the MainStreet Subsidiaries whose assets, individually or in the aggregate, constitute more than ten percent (10%) of the consolidated assets of ▇▇▇▇▇▇▇▇▇▇.

▇▇

(▇) For purposes of this Agreement, a “Superior Proposal” means an unsolicited, bona fide written Acquisition Proposal made by a person or entity (or group of persons or entities acting in concert within the meaning of Rule 13d-5 under the Exchange Act) that the Board of Directors of MainStreet concludes in good faith, after consultation with its financial and outside legal advisors, taking into account all legal, financial, regulatory and other aspects of the Acquisition Proposal and including the terms and conditions of this Agreement (A) is more favorable to the stockholders of MainStreet from a financial point of view, than the transactions contemplated by this Agreement and (B) is fully financed or reasonably capable of being fully financed and reasonably likely to receive all required approvals of Governmental Authorities on a timely basis and otherwise reasonably capable of being completed on the terms proposed; provided that, for purposes of this definition of “Superior Proposal,” the Acquisition Proposal shall have the meaning assigned to such term in Section 5.5(c), except the reference to “ten percent (10%) or more” in such definition shall be deemed to be a reference to “a majority” and “Acquisition Proposal” shall only be deemed to refer to a transaction involving MainStreet or Franklin Community Bank.

(e) Except as otherwise provided in this Agreement (including Section 7.1), nothing in this Section 5.5 shall permit MainStreet to terminate this Agreement or affect any other obligation of MainStreet under this Agreement.

(f) MainStreet agrees that any violation of the restrictions set forth in this Section 5.5 by any representative of MainStreet shall be deemed a breach of this Section 5.5 by MainStreet.

(b) Each party hereto will promptly furnish to the other party copies of applications filed with all Governmental Authorities and copies of written communications received by such party from any Governmental Authority with respect to the transactions contemplated hereby. Each party will consult with the other party with respect to the obtaining of all Regulatory Approvals and other material consents from third parties advisable to consummate the transactions contemplated by this Agreement, and each party will keep the other party apprised of the status of material matters relating to completion of the transactions contemplated hereby. All documents that the parties or their respective subsidiaries are responsible for filing with any Governmental Authority in connection with the transactions contemplated hereby (including to obtain Regulatory Approvals) will comply as to form in all material respects with the provisions of applicable law.

5.9

Employee Benefit Plans.

(a) American at its election shall either: (i) provide generally to officers and employees of MainStreet and the MainStreet Subsidiaries, who at or after the Effective Date become employees of American or the American Subsidiaries (“MainStreet Continuing Employees”), employee benefits under the American Benefit Plans (with no break in coverage), on terms and conditions which are the same as for similarly situated officers and employees of American and the American Subsidiaries; or (ii) maintain for the benefit of the MainStreet Continuing Employees, the MainStreet Benefit Plans maintained by MainStreet immediately prior to the Effective Date; provided that American may take action to amend any MainStreet Benefit Plan immediately prior to the Effective Date to comply with any law or, so long as the benefits provided under those MainStreet Benefit Plans following such amendment are no less favorable to the MainStreet Continuing Employees than benefits provided by American to its officers and employees under any comparable American Benefit Plans, as necessary and appropriate for other business reasons.

(b) For purposes of participation, vesting and benefit accrual (except not for purposes of benefit accrual with respect to any plan in which such credit would result in a duplication of benefits) under the American Benefit Plans, service with or credited by MainStreet or any of the MainStreet Subsidiaries shall be treated as service with American. To the extent permitted under applicable law, American shall cause welfare American Benefit Plans maintained by American that cover the MainStreet Continuing Employees after the Effective Date to (i) waive any waiting period and restrictions and limitations for preexisting conditions or insurability (except for pre-existing conditions that were excluded, or restrictions or limitations that were applicable, under the MainStreet Benefit Plans), and (ii) cause any deductible, co-insurance, or maximum out-of-pocket payments made by the MainStreet Continuing Employees under welfare MainStreet Benefit Plans to be credited to such MainStreet Continuing Employees under welfare American Benefit Plans, so as to reduce the amount of any deductible, co-insurance or maximum out-of-pocket payments payable by such MainStreet Continuing Employees under welfare American Benefit Plans.

(c) Each employee of MainStreet or any MainStreet Subsidiary at the Effective Date whose employment is involuntarily terminated other than for cause by American after the Effective Date, but on or before the date that is six (6) months from the Effective Date, excluding any employee who has a contract providing for severance, shall be entitled to receive severance pay equal to two (2) weeks of pay, at his or her rate of pay in effect at the time of termination, for each full year of continuous service with MainStreet and American, subject to a minimum of six (6) weeks and a maximum of twenty-six (26) weeks of pay. Such severance payments will be in lieu of any payment under severance pay plans that may be in effect at MainStreet or any MainStreet Subsidiary prior to the Effective Date.

(d) With respect to MainStreet’s 401(k) plan, MainStreet shall cause such plan to be terminated effective immediately prior to the Effective Date, in accordance with applicable law and subject to the receipt of all applicable regulatory or governmental approvals. Each MainStreet Continuing Employee who was a participant in the MainStreet 401(k) plan and who continues in the employment of American or any American Subsidiary shall be eligible to participate in American’s 401(k) plan on or as soon as administratively practicable after the Effective Date, and account balances under the terminated MainStreet 401(k) plan will be eligible for distribution or rollover, including direct rollover, to American’s 401(k) for MainStreet Continuing Employees. Any other former employee of MainStreet or the MainStreet Subsidiaries who is employed by American or the American Subsidiaries after the Effective Date shall be eligible to be a participant in the American 401(k) plan upon complying with eligibility requirements. All rights to participate in American’s 401(k) plan are subject to American’s right to amend or terminate the plan. For purposes of administering American’s 401(k) plan, service with MainStreet and the MainStreet Subsidiaries shall be deemed to be service with American for participation and vesting purposes, but not for purposes of benefit accrual.

(e) MainStreet and each of the MainStreet Subsidiaries, as applicable, shall adopt such resolutions and/or amendments to the Franklin Community Bank Supplemental Retirement Plan (the “MainStreet SERP”) and related documents and take any other necessary action to freeze the MainStreet SERP on or prior to the Effective Date. As soon as practicable after entering into this Agreement, MainStreet shall provide American with (i) certified copies of the resolutions and/or amendments adopted by the Board of Directors (or the appropriate committee thereof) of MainStreet or a MainStreet Subsidiary, as applicable, authorizing the above actions taken with respect to the MainStreet SERP, and (ii) executed amendments to the MainStreet SERP and related documents, including any required written consent of the participants in the MainStreet SERP, in form and substance reasonably satisfactory to American to effectuate such actions.

(f) Nothing in this Section 5.9 shall be interpreted as preventing American, from and after the Effective Date, from amending, modifying or terminating any American Benefit Plans or MainStreet Benefit Plans or any other contracts, arrangements, commitments or plans of either party in accordance with their terms and applicable law.

5.10

Reservation of Shares; NASDAQ Listing.

5.12

Indemnification; Insurance.

(a) Following the Effective Date, American shall indemnify, defend and hold harmless any person who has rights to indemnification from MainStreet, to the same extent and on the same conditions as such person was entitled to indemnification pursuant to applicable law and MainStreet’s Organizational Documents, as in effect on the date of this Agreement. Without limiting the foregoing, in any case in which corporate approval may be required to effectuate any indemnification, American shall direct, if the party to be indemnified elects, that the determination of permissibility of indemnification shall be made by independent counsel mutually agreed upon between American and the indemnified party.

(b) American shall, at or prior to the Effective Date, purchase a six (6) year “tail” prepaid policy on the same terms and conditions as the existing directors’ and officers’ liability (and fiduciary) insurance maintained by MainStreet from insurance carriers with comparable credit ratings, covering, without limitation, the Merger; provided, however, that the cost of such “tail” policy shall in no event exceed three hundred percent (300)% of the amount of the last annual premium paid by MainStreet for such existing directors’ and officers’ liability (and fiduciary) insurance. If, but for the proviso to the immediately preceding sentence, American would be required to expend more than three hundred percent (300)% of current annual premiums, American will obtain the maximum amount of that insurance obtainable by payment of annual premiums equal to three hundred percent (300)% of current annual premiums.

(c) The provisions of this Section 5.12 are intended to be for the benefit of and shall be enforceable by each indemnified party and his or her heirs and representatives.

5.13

Employment Arrangements.

American will, as of and after the Effective Date, assume and honor all employment, severance, change in control and deferred compensation agreements or arrangements that MainStreet and the MainStreet Subsidiaries have with their current and former officers and directors and which are set forth in Section 5.13 of the MainStreet Disclosure Schedule, except to the extent any such agreements or arrangements shall be superseded on or after the Effective Date.

Takeover Laws.

If any federal or state anti-takeover laws or regulations may become, or may purport to be, applicable to the transactions contemplated hereby, each party hereto and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary and legally permissible so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any such laws or regulations on any of the transactions contemplated by this Agreement.

5.17

Change of Method.

American and MainStreet shall be empowered, upon their mutual agreement and at any time prior to the Effective Date (and whether before or after the MainStreet Stockholders Meeting), to change the method or structure of effecting the combination of American and MainStreet (including the provisions of Article 1), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided that no such change shall (i) alter or change the Exchange Ratio or amount of cash to be received by MainStreet stockholders in exchange for each share of MainStreet Common Stock, (ii) adversely affect the tax treatment of

American or MainStreet pursuant to this Agreement or (iii) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The parties hereto agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 8.3.

Subject to the terms and conditions of the Agreement and Plan of Reorganization, dated as of August 24, 2014, between American and MainStreet (the “Agreement”), at the Effective Date (as defined herein), MainStreet shall be merged with and into American (the “Merger”) in accordance with the provisions of Virginia law, and with the effect set forth in Section 13.1-721 of the Virginia Stock Corporation Act (the “VSCA”).

At the Effective Date, by virtue of the Merger and without any action on the part of the stockholders of MainStreet and American, as the case may be, such stockholders will be entitled to the following:

A-1

(d) Each certificate previously representing shares of MainStreet Common Stock (a “MainStreet Common Certificate”) shall cease to represent any rights except the right to receive with respect to each underlying share of MainStreet Common Stock (i) the Merger Consideration upon the surrender of such MainStreet Common Certificate in accordance with Section 2.2, and (ii) any dividends or distributions or cash in lieu of financial shares which the holder thereof has the right to receive pursuant to Sections 2.4 and 2.6.

(e) Each share of MainStreet Common Stock held by either party and each share of American Common Stock held by MainStreet or any of the MainStreet Subsidiaries (as defined in the Agreement) prior to the Effective Date (in each case other than in a fiduciary or agency capacity or on behalf of third parties as a result of debts previously contracted) shall be cancelled and retired and shall cease to exist at the Effective Date and no consideration shall be issued in exchange therefor; provided, that such shares of American Common Stock shall resume the status of authorized and unissued shares of American Common Stock.

2.2

Exchange Procedures.

(a) On or before the Closing Date, American shall deposit, or shall cause to be deposited, with its transfer agent or such other transfer agent or depository or trust institution of recognized standing approved by American (in such capacity, the “Exchange Agent”), for the benefit of the holders of the MainStreet Common Certificates, (i) certificates representing the shares of American Common Stock issuable pursuant to this Article 2, and (ii) cash equal to the aggregate amount of the Cash Consideration issuable pursuant to this Article 2, together with any dividends or distributions with respect thereto and any cash to be paid in lieu of fractional shares without any interest thereon (the “Exchange Fund”), in exchange for certificates representing outstanding shares of MainStreet Common Stock.

(c) American shall cause the Merger Consideration into which shares of MainStreet Common Stock are converted at the Effective Date or dividends or distributions which such stockholder shall be entitled to receive and any cash to be paid in lieu of fractional shares to be issued and paid to such stockholder upon delivery to the Exchange Agent of MainStreet Common Certificates representing such shares of MainStreet Common Stock, together with the transmittal materials duly executed and completed in accordance with the instructions thereto. No interest will accrue or be paid on any such cash to be paid pursuant to Sections 2.4 or 2.6.

A-2

(e) Any portion of the Exchange Fund that remains unclaimed by the stockholders of MainStreet for six (6) months after the Effective Date shall be returned to American (together with any earnings in respect thereof). Any stockholders of MainStreet who have not complied with this Article 2 shall thereafter be entitled to look only to American, and only as a general creditor thereof, for payment of the consideration deliverable in respect of each share of MainStreet Common Stock such stockholder holds as determined pursuant to this Agreement, without any interest thereon.

(f) None of the Exchange Agent, American, MainStreet or any of the American Subsidiaries or the MainStreet Subsidiaries (as such terms are defined in the Agreement) shall be liable to any stockholder of MainStreet for any amount of property delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

2.3

MainStreet Stock Options.

(a) At the Effective Date, each option to purchase shares of MainStreet Common Stock (a “MainStreet Stock Option”) granted under an equity or equity-based compensation plan of MainStreet (a “MainStreet Stock Plan”) shall vest and shall be converted into an option (each, a “Replacement Option”) to acquire, on the same terms and conditions as were applicable under such MainStreet Stock Option (except as provided otherwise in this Section 2.3(a)), the number of shares of American Common Stock equal to the product of (i) the number of shares of MainStreet Common Stock subject to the MainStreet Stock Option multiplied by (ii) 0.643 (the “Option Exchange Ratio”). Such product shall be rounded down to the nearest whole number. The exercise price per share (rounded up to the next whole cent) of each Replacement Option shall equal (y) the exercise price per share of shares of MainStreet Common Stock that were purchasable pursuant to such MainStreet Stock Option divided by (z) the Option Exchange Ratio. Notwithstanding the foregoing, each MainStreet Stock Option that is intended to be an “incentive stock option” (as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”)) shall be adjusted in accordance with the requirements of Section 424 of the Code and all other options shall be adjusted in a manner that maintains the options exemption from Section 409A of the Code. At the Effective Date, American shall assume the MainStreet Stock Plans; provided that such assumption shall only be with respect to the Replacement Options and American shall have no obligation to make any additional grants or awards under the MainStreet Stock Plans.

2.7

Withholding Rights.

The Exchange Agent will be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any person such amounts, if any, as it is required to deduct and withhold with respect to the making of such payment under the Code (as defined in the Agreement) or any provision of state, local or foreign Tax (as defined in the Agreement) law. To the extent that amounts are so withheld and remitted to the appropriate Governmental Authority (as defined in the Agreement) by the Exchange Agent, such amounts withheld will be treated for all purposes of this Agreement as having been paid to such person in respect of which such deduction and withholding was made by the Exchange Agent.

2.8

Dissenting Shares.

A-4

the VSCA; provided, that no such payment shall be made to any dissenting stockholder unless and until such dissenting stockholder has complied with all applicable provisions of the VSCA, and surrendered to MainStreet the certificate or certificates representing the shares for which payment is being made. In the event that after the Effective Date a dissenting stockholder of MainStreet fails to perfect, or effectively withdraws or loses, such holder’s right to appraisal of and payment for such holder’s shares, American shall issue and deliver the consideration to which such holder of shares of MainStreet Common Stock is entitled under this Article 2 (without interest) upon surrender by such holder of the MainStreet Common Certificate representing such shares.

(f) Consents and Approvals. The execution and delivery of this Agreement by the Stockholder does not, and the performance by the Stockholder of his or her obligations under this

Agreement and the consummation by him or her of the transactions contemplated hereby will not, require the Stockholder to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any Governmental Authority.

(g) Absence of Litigation. There is no suit, action, investigation or proceeding pending or, to the knowledge of the Stockholder, threatened against or affecting the Stockholder or any of his or her affiliates before or by any Governmental Authority that could reasonably be expected to materially impair the ability of the Stockholder to perform his or her obligations hereunder or to consummate the transactions contemplated hereby.
