Exhibit 2.1

Section 2. Conversion, Exchange and Cancellation of Shares

2.1 General. The manner of converting and exchanging First National Common Stock, all of which is represented by outstanding share certificates, into the Merger Consideration shall be as hereinafter provided in this Section 2.

2.2 Conversion of First National Common Stock. Each share of First National Common Stock issued and outstanding immediately prior to the Effective Time, other than any Dissenting Shares, Treasury Stock and any share of First National Common Stock held by any wholly-owned subsidiary of First National, shall automatically be converted into the right to receive (i) stock consideration in accordance with subparagraphs (a) and (b), (ii) Cash Consideration in accordance with subparagraphs (c) and (e), and (iii) Additional Cash Consideration in accordance with subparagraphs (d) and (e) (collectively, the “Merger Consideration”), as follows:

(a) 1.725 fully paid and non-assessable shares of Premier Common Stock (determined by dividing (n) 1,436,600 by (d) the number of shares of First National Common Stock issued and outstanding at the Effective Time, which as of June 29, 2015 is 832,812); provided, however, if

(b) The weighted average of the daily closing trade prices of Premier Common Stock on the NASDAQ Global Market System during the twenty (20) consecutive NASDAQ Global Market System trading days ending on the trading day before the Effective Time, rounded to the nearest whole cent (“Premier's Trading Price”) is greater than $15.50 then the Exchange Ratio shall be reduced and calculated as follows: (n) $22,267,300 divided by (d) Premier's Trading Price, with that quotient further divided by (dd) the number of shares of First National Common Stock outstanding as of the Effective Time. The lower ratio determined pursuant to (a) or (b), rounded to the nearest thousandth, shall be hereinafter referred to as the “Exchange Ratio”. The Exchange Ratio, as adjusted pursuant to this Section 2.2(b) shall not be less than 1.650.

(c) If Premier's Trading Price is less than $15.50, then, subject to the limitation set forth in subparagraph (e), Premier shall pay up to an additional $1.20 in cash for each share of First National Common Stock, the exact amount to be calculated as follows: $15.50 less Premier's Trading Price multiplied by 1.725 (the “Cash Consideration”). In no event, however, shall the sum of Cash Consideration and Additional Cash Consideration defined in subparagraph (d) below exceed the sum of $1.20 per share of First National Common Stock.

(d) If First National’s Special Dividend approved and paid is less than $5.08 per share, then, subject to the limitation set forth in subparagraph (e) Premier shall pay further additional cash consideration of up to $1.00 for each share of First National Common Stock (the “Additional Cash Consideration”), however, Additional Cash Consideration is payable if, and only if, the Estimated PreClosing Shareholders’ Equity described in Section 6(d) equals or exceeds $21,836,000.

(e) In no event shall the total of the Cash Consideration and the Additional Cash Consideration exceed $1.20 per First National share, or $1,000,000 in the aggregate.

- 5 -

Exhibit 2.1

(f) In the event that the sum of the Special Dividend and the Merger Consideration, based on Premier’s Trading Price, the Cash Consideration and the Additional Cash Consideration, would be less than $27.50 per share of First National, then this Agreement may be terminated by First National, on written notice to Premier; provided that Premier may, at its sole option and discretion, increase the Merger Consideration so that the sum of the Special Dividend and the Merger Consideration is equal to $27.50 per share, whereupon no termination shall have occurred pursuant to this Section 2.2(f), and this Agreement shall remain in effect in accordance with its terms (except as the applicable Merger Consideration shall have been so modified); provided further, that the change of the Merger Consideration by Premier may not adversely affect the tax treatment of the transactions as contemplated herein and specifically in Section 6(n) hereof.

(g) In the event that the sum of the Special Dividend and the Merger Consideration, based on Premier’s Trading Price, the Cash Consideration and the Additional Cash Consideration, would be greater than $36.14 per share of First National, then this Agreement may be terminated by Premier, on written notice to First National; provided that First National may, at its sole option and discretion, decrease the Merger Consideration so that the sum of the Special Dividend and the Merger Consideration is equal to $36.14 per share, whereupon no termination shall have occurred pursuant to this Section 2.2(g), and this Agreement shall remain in effect in accordance with its terms (except as the applicable Merger Consideration shall have been so modified); provided further, that the change of the Merger Consideration may not adversely affect the tax treatment of the transactions as contemplated herein and specifically in Section 6(n) hereof.

(h) Treasury Shares. Each share of First National Common Stock held as Treasury Stock immediately prior to the Effective Time shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefore.

2.3 Manner of Exchange. After the Effective Time of the Merger, except for persons who may have dissenters’ rights pursuant to WVBCA and who exercise any rights they may have as dissenting shareholders of First National, if any, each holder of a certificate theretofore evidencing outstanding shares of First National Common Stock, upon surrender of such certificate, accompanied by a Letter of Transmittal, to Premier shall be entitled to receive in exchange therefor a certificate or certificates representing the number of full shares of Premier Common Stock, Cash Consideration and Additional Cash Consideration for which shares of First National Common Stock theretofore represented by the certificate or certificates so surrendered shall have been exchanged as provided in this Section 2, without interest. Premier, or its Exchange Agent shall mail such Letter of Transmittal to First National shareholders no later than three (3) business days after the Effective Time. Until so surrendered, each outstanding certificate which, prior to the Effective Time of the Merger, represented First National Common Stock will be deemed to evidence the right to receive the number of full shares of Premier Common Stock, Cash Consideration and Additional Cash Consideration into which the shares of First National Common Stock represented thereby may be converted, and will be deemed for all corporate purposes of Premier to evidence ownership of the number of full shares of Premier Common Stock, Cash Consideration and Additional Cash Consideration into which the shares of First National Common Stock

- 6 -

Exhibit 2.1

represented thereby were converted. Until such outstanding certificates formerly representing First National Common Stock are surrendered, no dividend payable to holders of record of Premier Common Stock for any period as of any date subsequent to the Effective Time of the Merger shall be paid to the holder of such outstanding certificates in respect thereof. After the Effective Time of the Merger there shall be no further registry of transfers on the records of First National of shares of First National Common Stock. Upon surrender of certificates of First National Common Stock for exchange for Premier Common Stock, Cash Consideration and Additional Cash Consideration, there shall be paid to the record holder of the certificates of Premier Common Stock issued in exchange therefor (i) the amount of dividends theretofore paid with respect to such full shares of Premier Common Stock as of any record date subsequent to the Effective Time of the Merger which have not yet been paid to a public official pursuant to abandoned property laws and (ii) at the appropriate payment date the amount of dividends with a record date after the Effective Time of the Merger, but prior to surrender and a payment date subsequent to surrender. No interest shall be payable with respect to such dividends upon surrender of outstanding certificates.

2.4 Fractional Shares. Premier will not issue fractional shares or fractional share certificates, but in lieu of the issuance of fractional shares will pay cash, without interest, to any First National shareholder otherwise entitled to receive such fractional shares. The amount of such cash payment will be determined by multiplying the fractional share interest to which a First National shareholder would otherwise be entitled by Premier’s Trading Price. Payment for fractional shares will be made with respect to each shareholder at the time such shareholder’s certificates of First National Common Stock are exchanged.

2.5 Lost Certificates. If a certificate evidencing outstanding shares of First National Common Stock is lost, stolen or destroyed, the registered owner thereof shall be entitled to receive the Premier certificate and cash, without interest, to which he would otherwise be entitled on exchange of such certificate, by notifying Premier in writing of such lost, stolen or destroyed certificate and giving Premier evidence of loss and a bond sufficient to indemnify Premier against any claim that may be made against it on account of the alleged lost, stolen or destroyed certificate and the issuance of the certificate and cash.

Exhibit 2.1

Section 3. Representations, Warranties and Covenants of Premier

Standard. No representation or warranty of Premier contained in Section 3 or of First National contained in Section 4 shall be deemed untrue, inaccurate or incorrect for any purpose under this Agreement, and no party hereto shall be deemed to have breached a representation or warranty for any purpose under this Agreement, in any case as a consequence of the existence or absence of any fact, circumstance or event unless such fact, circumstance or event, individually or when taken together with all other facts, circumstances or events inconsistent with any representations or warranties contained in Section 3, in the case of Premier, or Section 4, in the case of First National, has had or would reasonably be expected to have a Material Adverse Effect with respect to Premier or a Material Adverse Effect with respect to First National, (disregarding for purposes of Section 3 and Section 4 all qualifications or limitations set forth in any representations or warranties as to “materiality,” “Material Adverse Effect,” and words of similar import). Notwithstanding the immediately preceding sentence, the representations and warranties contained in Section 3.2 and Section 4.2 shall be deemed untrue and incorrect if not true and correct except to a de minimis extent.

Except as disclosed in the Disclosure Letter (as defined in Section 14.15), Premier hereby represents and warrants to and covenants with First National that:

3.1 Organization, Standing and Authority. Premier is a corporation validly existing and in good standing under the laws of the Commonwealth of Kentucky, and is a duly registered bank holding company under the provisions of the Bank Holding Company Act of 1956, as amended. Premier has the corporate power to execute and deliver this Agreement, and has taken all action required by law, its Articles of Incorporation, its By-laws or otherwise, to authorize such execution and delivery, the Merger, the Subsidiary Merger and the consummation of the transactions contemplated hereby, and this Agreement is a valid and binding agreement of Premier in accordance with its terms. At the Effective Time, Premier will have corporate power to carry on its business as then to be conducted and will be qualified to do business in every jurisdiction in which the character and location of the assets to be owned by it or the nature of the business to be transacted by it require qualification.

3.2 Capital Structure. The authorized capital stock of Premier consists of 20,000,000 shares of Premier Common Stock, of which 8,167,806 shares are currently issued and outstanding and 1,000,000 shares of Premier Preferred Stock, none of which are currently issued and outstanding. All of such shares are fully paid and non-assessable. Premier does not have any other shares of Premier Common Stock or Premier Preferred Stock or any other capital stock issued or outstanding. Premier does not have any outstanding subscriptions, options or other agreements or commitments obligating it to issue shares of its capital stock except that Premier has reserved 640,659 shares of Premier Common Stock to be issued upon the exercise of stock options granted to certain Premier employees.

As of June 29, 2015, 286,409 option grants for Premier Common Stock were outstanding, of which 204,675 were immediately exercisable. The holders of Premier Common Stock have no preemptive rights with respect to the issuance of additional authorized shares of Premier Common Stock. Nothing in this Agreement shall prohibit or impair the ability and right of Premier to increase its authorized capital stock, or issue or

- 8 -

Exhibit 2.1

agree to commit to issue additional shares of its capital stock, and any increase in authorized capital stock, or issuance, or agreement or commitment to issue, additional shares of Premier Common Stock (other than an issuance, or agreement or commitment to issue, resulting from a stock dividend, stock split, or reverse stock split) shall not alter or affect the Merger Consideration set forth in Section 2.2 hereof.

3.3 Premier Subsidiaries. At the date of this Agreement, Premier has two (2) state bank subsidiaries, as follows:

(a) Premier State Banks:

Premier Bank, Inc.; and

Citizens Deposit Bank and Trust, Inc.

hereinafter referred to as “Premier State Banks”.

The Premier State Banks are hereinafter jointly referred to as the “Premier Subsidiaries”.

Except for the Premier State Banks, Premier has no subsidiaries.

Each of the Premier State Banks is a banking corporation, duly organized, validly existing under the laws of either the State of West Virginia, or the Commonwealth of Kentucky, and has the corporate power and is duly authorized to own all of its properties and assets and to carry on its business as is now being conducted. Premier owns all of the issued and outstanding capital stock of each of the Premier Subsidiaries, free and clear of any liens, claims, security interest, encumbrances, charges or rights of third parties of any kind whatsoever, except that (i) 25% of Premier’s 100% interest in Premier Bank is pledged as collateral for a $4,700,000 loan and $3,000,000 line of credit from First Guaranty Bank of Hammond, Louisiana and (ii) 100% of Premier’s 100% interest in Citizens Deposit Bank is pledged as collateral for a $5,700,000 loan and a $5,000,000 line of credit from The Bankers’ Bank of Kentucky, Inc. of Frankfort, Kentucky.

Nothing in this Agreement shall prohibit or impair the ability and right of Premier or any Premier Subsidiary to create or acquire, or agree to create or acquire, any other subsidiaries or entities or to acquire, consolidate or merge with any other company, corporation, bank or banking association, or to acquire or establish any branch prior to the Effective Time, provided however that none of the transactions described in this paragraph shall adversely affect Premier’s ability to fulfill its obligations under this Agreement or result in the imposition of a burdensome condition by a regulatory authority.

3.4 Authority. The execution and delivery of this Agreement do not, and the consummation of the Merger, the Subsidiary Merger and transactions contemplated hereby will not, violate any provision of the Articles of Incorporation or By-laws of Premier, or any provision of, or result in the acceleration of any obligation under, any material mortgage, deed of trust, note, lien, lease, franchise, license, permit, agreement, instrument, order,

- 9 -

Exhibit 2.1

arbitration award, judgment, injunction or decree, or result in the termination of any material license, franchise, lease, or permit to which Premier is a party or by which it is bound, and will not violate or conflict with any other material restriction of any kind or character to which Premier is subject.

The Premier Financial Statements (as of the dates thereof and for the periods covered thereby):

(a) are in accordance with the books and records of Premier, which are complete and correct in all material respects that are required by generally accepted accounting principles (except as otherwise required or approved by applicable regulatory authorities or by applicable law) and which have been maintained in accordance with good business practices; and

(b) present fairly, in all material respects, the financial position and results of operations and cash flows of Premier as of the dates and for the periods indicated, in accordance with generally accepted accounting principles (except as otherwise required or approved by applicable regulatory authorities or by applicable law), applied on a basis consistent with prior years, and do not fail to disclose any material extraordinary or out-of-period items.

Premier’s unaudited Balance Sheet and the related unaudited Statements of Income and Statements of Changes in Cash Flows, for the calendar quarter and year-to-date periods ended March 31, 2015, and for each calendar quarter thereafter until the Effective Time, all of which Premier shall deliver to First National as soon as practicable, will be prepared in accordance with accounting principals consistently applied and will fairly present Premier’s financial condition and results of operations as of such date and for such periods, except for footnote disclosures, which generally do not include all of the disclosures normally required for annual financial statements.

3.8 Absence of Undisclosed Liabilities. At December 31, 2014 and March 31, 2015, none of Premier or the Premier Subsidiaries had any obligation or liability (contingent or otherwise) which was material, or which when combined with all similar obligations or liabilities would have been material, to Premier (i) except as disclosed in the Premier Financial Statements and (ii) except, in the case of any of the Premier State Banks, for unfunded loan commitments made in the ordinary course of their respective businesses and consistent with generally accepted banking practices; nor does there exist a set of circumstances resulting from transactions effected or events occurring on or prior to December 31, 2014, or from any action omitted to be taken during such period that, to the knowledge of Premier, could reasonably be expected to result in any such material obligation or liability, except as disclosed or provided for in the Premier Financial Statements. The amounts set up as liabilities for taxes in the Premier Financial Statements are sufficient for the payment of all respective taxes (including, without limitation, federal, state, local and foreign excise, franchise, property, payroll, income, capital stock and sales and use taxes) accrued in accordance with generally accepted accounting principles and unpaid at December 31, 2014. Since December 31, 2014, none of Premier or the Premier Subsidiaries has incurred or paid any obligation or liability which would be material (on a consolidated basis) to Premier, except for obligations incurred or paid in connection with transactions by it in the ordinary course of its business consistent with generally accepted banking practices and except as disclosed herein.

(b) None of Premier or the Premier Subsidiaries has executed an extension or waiver of any statute of limitations on the assessment or collection of any tax due that is currently in effect.

(c) To the extent any federal, state, local or foreign taxes are due from any of Premier or the Premier Subsidiaries for the period or periods beginning January 1, 2015, or thereafter through and including the Effective Time, adequate provision on an estimated basis has been or will be made for the payment of such taxes by establishment of appropriate tax liability accounts on the last monthly financial statements of Premier or the Premier Subsidiaries prepared before the Effective Time.

To the best knowledge and belief of Premier management, all buildings, and all fixtures, equipment and other property and assets which in the opinion of management are material to its business on a consolidated basis, held under leases or subleases by any of Premier and the Premier Subsidiaries, as the case may be, are held under valid instruments enforceable in accordance with their respective terms (except as previously disclosed in writing to First National and except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and except that the availability of the equitable remedy of specific performance or injunctive relief is subject to the discretion of the court before which any proceedings may be brought).

PLAN OF MERGER

FIRST NATIONAL BANKSHARES CORPORATION

AND

FIRST NATIONAL ACQUISITION, INC.

1. The Parties. First National Acquisition, Inc., a West Virginia corporation ("Interim Company") shall merge with and into First National Bankshares Corporation, a West Virginia corporation (“First National”) (both corporations are sometimes collectively referred to herein as the "Constituent Corporations") under the charter of First National. First National shall be (and is hereinafter called when reference is made to it at and after the consummation of the Merger) the Surviving Company. The Merger shall become effective at the time specified in articles of merger to be filed with the Secretary of State of West Virginia (the "Effective Time of the Merger").

2. Articles of Incorporation; Bylaws. At the Effective Time of the Merger, the Articles of Incorporation and Bylaws of First National in effect at the Effective Time of the Merger shall be the Articles of Incorporation and Bylaws of the Surviving Company until altered, amended or repealed in accordance with applicable law.

3. Assets and Rights. At the Effective Time of the Merger, the corporate existence of Interim Company shall, as provided in the West Virginia Business Corporation Act, be merged with and into First National and continued in the Surviving Company. The Surviving Company shall thereupon and thereafter possess all of the rights, privileges, immunities and franchises, of a public as well as of a private nature, of the Constituent Corporations; and all property, real,

Exhibit 2.1

personal and mixed, and all debts due on whatever account, including subscriptions to shares, if any, and all other choses in action, and all and every other interest of or belonging to or due to the Constituent Corporations, and each of them, shall be deemed to be transferred to and vested in the Surviving Company without further act or deed; and the title to any real estate, or any interest therein, vested in the Constituent Corporations, and each of them, before the Merger, shall not revert or in any way be impaired by reason of the Merger.

4. Liabilities and Obligations. At the Effective Time of the Merger, First National as the Surviving Company shall henceforth be and remain responsible and liable for all the liabilities and obligations of the Constituent Corporations; and neither the rights of creditors nor any liens upon the property of either of the Constituent Corporations shall be impaired by the Merger.

5. Conversion, Exchange and Cancellation of Shares

(i) Conversion Rate. At the Effective Time of the Merger each outstanding share of First National Common Stock shall ipso facto, without any action on the part of the holder thereof, become and be converted into the right to receive (i) stock consideration in accordance with subparagraphs (a) and (b), (ii) Cash Consideration in accordance with subparagraphs (c) and (e), and (iii) Additional Cash Consideration in accordance with subparagraphs (d) and (e) (collectively, the “Merger Consideration”), as follows:

Exhibit 2.1

(b) The weighted average of the daily closing trade prices of Premier Common Stock on the NASDAQ Global Market System during the twenty (20) consecutive NASDAQ Global Market System trading days ending on the trading day before the Effective Time (“Premier's Trading Price”) is greater than $15.50 then the Exchange Ratio shall be reduced and calculated as follows: (n) $22,267,300 divided by (d) Premier's Trading Price, with that quotient further divided by (dd) the number of shares of First National Common Stock outstanding as of the Effective Time. The lower ratio determined pursuant to (a) or (b), rounded to the nearest thousandth, shall be hereinafter referred to as the “Exchange Ratio”. The Exchange Ratio, as adjusted pursuant to this subparagraph (b) shall not be less than 1.650.

(d) If First National’s Special Dividend approved and paid is less than $5.08 per share, then, subject to the limitation set forth in subparagraph (e) Premier shall pay further additional cash consideration of up to $1.00 for each share of First National Common Stock (the “Additional Cash Consideration”); however, Additional Cash Consideration is payable if, and only if, the Estimated PreClosing Shareholders’ Equity described in Section 6(d) of the Agreement of Merger equals or exceeds $21,836,000.

(e) In no event shall the total of the Cash Consideration and the Additional Cash Consideration exceed $1.20 per First National share, or $1,000,000 in the aggregate.

Exhibit 2.1

(f) In the event that the sum of the Special Dividend and the Merger Consideration, based on Premier’s Trading Price, the Cash Consideration and the Additional Cash Consideration, would be less than $27.50 per share of First National, then this Plan may be terminated by First National, on written notice to Premier; provided that Premier may, at its sole option and discretion, increase the Merger Consideration to $27.50 per share, whereupon no termination shall have occurred pursuant to this Section 2.2(f), and this Plan shall remain in effect in accordance with its terms (except as the applicable Merger Consideration shall have been so modified); provided further, that the change of the Merger Consideration by Premier may not adversely affect the tax treatment of the transactions as contemplated herein and specifically in Section 6(n) of the Merger Agreement.

(g) In the event that the sum of the Special Dividend and the Merger Consideration, based on Premier’s Trading Price, the Cash Consideration and the Additional Cash Consideration, would be greater than $36.14 per share of First National, then this Plan may be terminated by Premier, on written notice to First National; provided that First National may, at its sole option and discretion, decrease the Merger Consideration to $36.14 per share, whereupon no termination shall have occurred pursuant to this Section 2.2(g), and this Plan shall remain in effect in accordance with its terms (except as the applicable Merger Consideration shall have been so modified); provided further, that the change of the Merger Consideration may not adversely affect the tax treatment of the transactions as contemplated herein and specifically in Section 6(n) of the Merger Agreement.

Exhibit 2.1

All shares of Premier Common Stock into which the aforesaid First National Common Stock is so converted shall be fully paid and non-assessable.

(ii) Manner of Exchange. After the Effective Time of the Merger, except for persons exercising their rights as dissenting shareholders of First National, each shareholder of First National, upon surrender to Premier of certificates representing First National Common Stock, accompanied by a Letter of Transmittal, shall be entitled to receive in exchange therefor a certificate or certificates representing the number of full shares of Premier Common Stock, Cash Consideration and Additional Cash Consideration for which shares of First National Common Stock theretofore represented by the certificate or certificates so surrendered shall have been exchanged as provided in this Section 5. After the Effective Time of the Merger, each outstanding certificate which, prior to the Effective Time of the Merger, represented First National Common Stock, will be deemed for all corporate purposes of Premier to evidence ownership of the number of full shares of Premier Common Stock, Cash Consideration and Additional Cash Consideration into which the shares of First National Common Stock represented thereby were converted. Until such outstanding certificates formerly representing First National Common Stock are surrendered, no dividend payable to holders of record of Premier Common Stock for any period as of any date subsequent to the Effective Time of the Merger shall be paid to the holder of such outstanding certificates in respect thereof. After the Effective Time of the Merger there shall be no further registry of transfers on the records of First National of shares of First National Common Stock. Upon surrender of certificates of First National Common Stock for exchange for Premier Common Stock, there shall be paid to the record holder of the certificates of Premier Common Stock, Cash Consideration and Additional Cash Consideration issued in exchange therefor the

Exhibit 2.1

amount of dividends theretofore paid with respect to such full shares of Premier Common Stock as of any date subsequent to the Effective Time of the Merger which have not yet been paid to a public official pursuant to abandoned property laws and at the appropriate payment date the amount of dividends with a record date after the Effective Time of the Merger, but prior to surrender and a payment date subsequent to surrender. No interest shall be payable with respect to such dividends upon surrender of outstanding certificates.

(iii) Fractional Shares. Premier will not issue fractional shares or fractional share certificates, but in lieu of the issuance of fractional shares will pay cash, without interest, to any First National shareholder otherwise entitled to receive such fractional shares. The amount of such cash payment will be determined by multiplying the fractional share interest to which a First National shareholder would otherwise be entitled by Premier’s Trading Price. Payment for fractional shares will be made with respect to each shareholder at the time such shareholder's certificates of First National Common Stock are exchanged.

(iv) Lost Certificates. If a certificate evidencing outstanding shares of First National Common Stock is lost, stolen or destroyed, the registered owner thereof shall be entitled to receive the Premier certificate to which the shareholder would otherwise be entitled on surrender of such certificate, by notifying Premier in writing of such lost, stolen or destroyed certificate and giving Premier evidence of loss and a bond sufficient to indemnify Premier against any claim that may be made against it on account of the alleged lost, stolen and destroyed certificate and the issuance of the certificate and cash.

6. Further Assurances. If at any time the Surviving Company shall consider or be advised that any further assignments, conveyances or assurances are necessary or desirable to vest, perfect or confirm in the Surviving Company the title to any property or rights of Interim Company or First National or any subsidiary thereof, or otherwise to carry out the provisions hereof, the proper officers and directors of Interim Company or First National, as the case may be, as of the Effective Time of the Merger, and thereafter the officers of the Surviving Company acting on behalf of Interim Company or First National, as the case may be, shall execute and deliver any and all proper assignments, conveyances and assurances, and do all things necessary or desirable to vest, perfect or confirm title to such property or rights in the Surviving Company and otherwise carry out the provisions hereof.

Exhibit 2.1

7. Termination and Abandonment. This Plan of Merger may be terminated and the Merger abandoned as provided in the Agreement of Merger.

8. Other Terms and Conditions. All other terms and conditions to the Merger are as provided in the Agreement of Merger.

IN WITNESS WHEREOF, each of the parties hereto has caused this Plan of Merger to be executed on its behalf and its corporate seal to be hereunto affixed and attested by its corporate officers thereunto duly authorized, all as of the day and year first above written.
