Any transfer, pledge or assignment of said stock certificate or all or any portion of the shares of Common Stock represented thereby, whether absolute or contingent, outright or as collateral, voluntary or involuntary or by action of law (in each case a “Transfer”), shall be deemed to and shall include the assignment or transfer of a pro-rata portion of the Warrant granted hereunder.

4. Beneficial Owners.

4.1. Nominees for Beneficial Owners. In the event that any Warrant Agreement, Warrant or Warrant Stock is held by a nominee for a beneficial owner thereof, the beneficial owner shall not be treated as the owner or holder of this Warrant Agreement or the Warrant granted hereunder or any Warrant Stock issued pursuant hereto unless such beneficial ownership is clearly disclosed and reflected on the face of this Warrant Agreement and the stock

-3-

certificate evidencing the Qualifying Stock or, in the case of Warrant Stock, the stock certificate evidencing the Warrant Stock. If the beneficial ownership is so reflected, then the beneficial owner may, at its election, be treated as the Grantee of such Warrant Agreement, Warrant or Warrant Stock for purposes of any request or other action by any Grantee or Grantees pursuant to this Agreement. If the beneficial owner of any Warrant Stock does so elect, the Bank may require assurances reasonably satisfactory to Bank of such owner’s beneficial ownership of such Warrant Stock.

5. Adjustment of Number of Shares; Exercise Price; and Nature of Securities Issuable Upon Exercise of Warrants.

5.1. Exercise Price; Adjustment of Number of Shares. The Exercise Price set forth in Section 1.1 hereof shall be subject to equitable adjustment up or down from time to time to reflect stock splits, stock dividends, reverse stock splits, mergers, consolidation, and other forms of recapitalization, or reorganization, but only as hereinafter provided. No Warrant shall be “repriced” simply to reflect a reduction in the market price of Common Stock. Upon each adjustment of the Exercise Price, the Grantees shall thereafter be entitled to purchase at the Exercise Price resulting from such adjustment a number of shares obtained by multiplying the Exercise Price immediately prior to such adjustment by the number of shares purchasable pursuant hereto immediately prior to such adjustment and dividing the product thereof by the Exercise Price resulting from such adjustment.

5.2. Reorganization; Reclassification; Consolidation; Merger; or Sale. If any capital reorganization or reclassification of the capital stock of the Bank, or any consolidation or merger of the Bank with another corporation, or the sale of all or substantially all of its assets to another corporation shall be effected in such a way that Holders of Common Stock shall be entitled to receive stock, securities, cash or assets with respect to or in exchange for Common Stock, then, as a condition of such reorganization, reclassification, consolidation, merger or sale, lawful and adequate provisions shall be made whereby the Grantees shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions specified in this Warrant Agreement, upon exercise of the Warrant contained herein and in lieu of the Warrant Shares immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby, such shares of stock, securities, cash or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of Common Stock equal to the number of Warrant Shares immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby, and in any such case appropriate provision shall be made with respect to the rights and interest of the Grantees to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Exercise Price and of the number of Warrant Shares purchasable and receivable upon the exercise of the Warrant contained herein) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock or securities thereafter deliverable upon the exercise hereof.

5.3. Stock Splits, Stock Dividends and Reverse Stock Splits. In case at any time the Bank shall subdivide its outstanding shares of Common Stock into a greater number of shares, or shall declare and pay any stock dividend with respect to its outstanding stock that has the effect of increasing the number of outstanding shares of Common Stock, the Exercise Price in effect immediately prior to such subdivision or stock dividend shall be proportionately

-4-

reduced and the number of Warrant Shares purchasable pursuant to this Warrant Agreement immediately prior to such subdivision or stock dividend shall be proportionately increased, and conversely, in case at any time the Bank shall combine its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares purchasable upon the exercise of the Warrant contained herein immediately prior to such combination shall be proportionately reduced.

5.4. Bank to Prevent Dilution. In case at any time or from time to time any event shall occur or condition shall arise by reason of action taken by the Bank as to which the other provisions of this Section 5 are not strictly applicable and which might materially and adversely affect the exercise rights represented by this Warrant Agreement, the Bank shall determine the adjustment, if any, on a basis consistent with the standards established in the other provisions of this Section 5, necessary with respect to the Exercise Price and the number of Warrant Shares, so as to preserve, without dilution, the exercise rights represented by this Warrant Agreement.

6. Registration; Transfer; Exchange; and Replacement of Warrant Agreement.

7. The Bank shall keep at its principal office or cause its transfer agent to keep at such agent’s office a register in which the Bank shall provide for the registration, transfer and exchange of this Warrant Agreement and the Qualifying Common Shares to which it is attached.

The Bank may deem and treat the person in whose name the Qualifying Common Shares to which the Warrant granted hereunder is attached are registered as the holder and owner hereof, without regard to the name reflected herein as Grantee for all purposes and shall not be affected by any notice to the contrary, until this Warrant Agreement and the stock certificate representing such Qualifying Common Shares are duly presented for registration or Transfer.

8. Elimination of Fractional Interests.

The Bank shall not be required upon the exercise of the Warrant evidenced hereby to issue stock certificates representing fractions of shares of Common Stock, but shall honor such Warrant only to the extent of the number of whole shares to which Grantee is entitled.

9. Reservation and Listing of Shares.

The Bank shall at all times reserve and keep available out of its authorized shares of Common Stock, solely for the purpose of issuance upon the exercise of the Warrant granted herein, such number of shares of Common Stock as shall be issuable upon the exercise hereof. The Bank covenants and agrees that, upon exercise of the Warrant granted herein and payment of the Exercise Price therefor, all shares of Common Stock issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable.

10. Supplying Information.

The Bank shall cooperate with Grantee and each holder of Warrant Stock issued upon exercise of the Warrant granted herein in supplying such information as may be reasonably

-5-

necessary for such Persons to complete and file any information reporting forms presently or hereafter required by the Commission or any state securities commission as a condition to the availability of an exemption from the Securities Act for the sale of such Warrant or shares of Warrant Stock. The Bank shall use reasonable efforts at all times following any public offering of the Bank’s Common Stock to make public information available so as to afford the Grantee and any Warrant Stock issued upon exercise of the Warrant granted hereunder the benefits of any available securities law exemptions in connection with resales which are or may become available.

11. Grantee’s Satisfaction and Agreement to be Bound.

This Warrant Agreement has been executed by Bank and accepted by Grantee in full satisfaction of its obligation to grant warrants to Grantee in connection with Grantee’s subscription for and purchase of the Qualifying Shares. Grantee agrees to accept the Warrant granted hereunder in full satisfaction of such obligation of Bank, and agrees to be bound by the terms hereof.

12. Loss or Mutilation.

Upon receipt by the Bank from Grantee of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of this Warrant Agreement and an indemnity reasonably satisfactory to it and, in case of mutilation, upon surrender and cancellation hereof, the Bank will execute and deliver in lieu hereof a new Warrant Agreement of like tenor to Grantee.

13. Office of the Bank.

As long as any of the Warrants remain outstanding, the Bank shall maintain an office or agency, which may be the principal executive offices of the Bank (the “Designated Office”), where the Warrant Agreements may be presented for exercise, registration of transfer, division or combination as provided in this Warrant Agreement. Such Designated Office shall initially be the office of the Bank at 201 4th Avenue, North, Suite 900, Nashville, Tennessee 37219.
