1 AGREEMENT AND PLAN OF MERGER This Agreement and Plan of Merger (this “Agreement”) is dated as of July 23, 2025, by and between Colony Bankcorp, Inc., a Georgia corporation (“CBAN”), and TC Bancshares, Inc., a Georgia corporation (“TCBC” and, together with CBAN, the “Parties” and each a “Party”). W I T N E S S E T H WHEREAS, the boards of directors of the Parties have determined that it is in the best interests of their respective companies and their respective shareholders to consummate the business combination transaction provided for in this Agreement in which TCBC will, on the terms and subject to the conditions set forth in this Agreement, merge with and into CBAN (the “Merger”), with CBAN as the surviving company in the Merger (sometimes referred to in such capacity as the “Surviving Entity”); WHEREAS, as an inducement to CBAN to enter into this Agreement, each executive officer and director of TCBC have entered into a voting agreement (each a “TCBC Voting Agreement” and collectively, the “TCBC Voting Agreements”), substantially in the form attached hereto as Exhibit A, dated as of the date hereof, with CBAN, pursuant to which each such executive officer, director or shareholder has agreed, among other things, to vote all shares of TCBC Stock owned by such executive officer, director or shareholder in favor of the approval of this Agreement and the transactions contemplated hereby, subject to the terms of the TCBC Voting Agreements; WHEREAS, as an inducement to TCBC to enter into this Agreement, each executive officer and director of CBAN has entered into a voting agreement (each a “CBAN Voting Agreement” and collectively, the “CBAN Voting Agreements”), substantially in the form attached hereto as Exhibit B, dated as of the date hereof, with CBAN, pursuant to which each such executive officer or director has agreed, among other things, to vote all shares of CBAN Common Stock owned by such executive officer or director in favor of the approval of this Agreement and the transactions contemplated hereby, subject to the terms of the CBAN Voting Agreements; WHEREAS, the Parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger; and WHEREAS, for federal income tax purposes, it is intended that each of the Merger and the Bank Merger (as defined herein) qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations promulgated thereunder (the “Code”), and this Agreement is intended to be and is adopted as a “plan of reorganization” for each of the Merger and the Bank Merger for purposes of Sections 354 and 361 of the Code. NOW, THEREFORE, in consideration of the mutual promises herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

2 ARTICLE I THE MERGER Section 1.01 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Georgia Business Corporation Code (the “GBCC”), at the Effective Time, TCBC shall merge with and into CBAN pursuant to the terms of this Agreement. CBAN shall be the Surviving Entity in the Merger and shall continue its existence as a corporation under the laws of the State of Georgia. As of the Effective Time, the separate corporate existence of TCBC shall cease. Section 1.02 Articles of Incorporation and Bylaws; Officers and Directors. (a) At the Effective Time, the articles of incorporation of CBAN in effect immediately prior to the Effective Time shall be the articles of incorporation of the Surviving Entity until thereafter amended in accordance with applicable Law. The bylaws of CBAN in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Entity until thereafter amended in accordance with applicable Law and the terms of such bylaws. (b) The directors of CBAN in office immediately prior to the Effective Time shall serve as the directors of the Surviving Entity in accordance with the bylaws of the CBAN. (c) The officers of CBAN in office immediately prior to the Effective Time, together with such additional persons as may thereafter be appointed, shall serve as the officers of the Surviving Entity from and after the Effective Time in accordance with the bylaws of the Surviving Entity. Section 1.03 Bank Merger. Immediately following the Effective Time, TC Federal Bank, a federal savings association and a direct wholly-owned subsidiary of TCBC (“TC Federal Bank”), shall be merged (the “Bank Merger”) with and into Colony Bank, a Georgia state-chartered bank and a direct wholly-owned subsidiary of CBAN, in accordance with the provisions of applicable federal and state banking laws and regulations, and Colony Bank shall be the surviving bank (the “Surviving Bank”). The Bank Merger shall have the effects as set forth under applicable federal and state banking laws and regulations, and the board of directors of the Parties have, on the date hereof, caused the board of directors of Colony Bank and TC Federal Bank, respectively, to approve a separate merger agreement (the “Bank Plan of Merger”) in substantially the form attached hereto as Exhibit C, and have caused the Bank Plan of Merger to be executed and delivered on the date of this Agreement. Each of CBAN and TCBC shall also approve the Bank Plan of Merger in their capacities as sole shareholders of Colony Bank and TC Federal Bank, respectively. As provided in the Bank Plan of Merger, the Bank Merger may be abandoned at the election of Colony Bank at any time, whether before or after filings are made for regulatory approval of the Bank Merger, but if the Bank Merger is abandoned for any reason, TC Federal Bank shall continue to operate under its name; provided that prior to any such election, CBAN shall (a) reasonably consult with TCBC and its regulatory counsel and (b) reasonably determine in good faith that such election will

3 not, and would not reasonably be expected to, prevent, delay or impair any Party’s ability to consummate the Merger or the other transactions contemplated by this Agreement. Section 1.04 Effective Time; Closing. (a) Subject to the terms and conditions of this Agreement, the Parties will make all such filings as may be required to consummate the Merger and the Bank Merger by applicable Laws. The Merger shall become effective as set forth in the articles of merger (the “Articles of Merger”) related to the Merger, which will include the plan of merger (the “Plan of Merger”), that shall be filed with the Secretary of State of the State of Georgia, as provided in the GBCC, on the Closing Date. The “Effective Time” of the Merger shall be the later of (i) the date and time of filing of the Articles of Merger, or (ii) the date and time when the Merger becomes effective as set forth in the Articles of ▇▇▇▇▇▇. Unless otherwise mutually agreed by the Parties, the Effective Time will occur on the first day of the calendar month following the day all of the conditions to the Closing set forth in Article VI (other than conditions to be satisfied at the Closing, which shall be satisfied or waived at the Closing) have been satisfied or waived in accordance with the terms hereof. (b) The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place on the Business Day prior to the Effective Time (such date, the “Closing Date”) by electronic means or such other place as the Parties may mutually agree. At the Closing, there shall be delivered to CBAN and TCBC the certificates and other documents required to be delivered under Article VI. Section 1.05 Additional Actions. If, at any time after the Effective Time, any Party shall consider or be advised that any further deeds, documents, assignments or assurances in Law or any other acts are necessary or desirable to carry out the purposes of this Agreement (such Party, the “Requesting Party”), the other Party and its Subsidiaries and their respective current and former officers and directors shall be deemed to have granted to the Requesting Party and its Subsidiaries, and each or any of them, an irrevocable power of attorney to execute and deliver, in such official corporate capacities, all such deeds, assignments or assurances in Law or any other acts as are necessary or desirable to carry out the purposes of this Agreement, and the officers and directors of the Requesting Party and its Subsidiaries, as applicable, are authorized in the name of the other Party and its Subsidiaries or otherwise to take any and all such action. Section 1.06 Reservation of Right to Revise Structure. CBAN may at any time and without the approval of TCBC change the method of effecting the business combination contemplated by this Agreement if and to the extent that it reasonably deems such a change to be necessary; provided, however, that no such change shall (a) alter or change the amount of the consideration to be issued to (i) Holders as Merger Consideration or (ii) holders of TCBC Options or TCBC Restricted Shares as currently contemplated in this Agreement, (b) reasonably be expected to materially impede or delay consummation of the Merger, (c) adversely affect the federal income tax treatment of Holders in connection with the Merger, or (d) require submission to or approval of TCBC’s shareholders after the plan of merger set forth in this

4 Agreement has been approved by TCBC’s shareholders. In the event that CBAN elects to make such a change, the Parties agree to cooperate to execute appropriate documents to reflect the change. ARTICLE II MERGER CONSIDERATION; EXCHANGE PROCEDURES Section 2.01 Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of the Parties or any shareholder of TCBC: (a) Each share of CBAN Common Stock that is issued and outstanding immediately prior to the Effective Time shall remain outstanding following the Effective Time and shall be unchanged by the Merger. (b) Each share of TCBC Stock owned directly by CBAN, TCBC, or any of their respective Subsidiaries (excluding shares held in the ESOP, in trust accounts, managed accounts and the like for the benefit of customers or shares held as collateral for outstanding debt previously contracted) immediately prior to the Effective Time shall be cancelled and retired at the Effective Time without any conversion thereof, and no payment shall be made with respect thereto (the “TCBC Cancelled Shares”). (c) Notwithstanding anything in this Agreement to the contrary, all shares of TCBC Stock that are issued and outstanding immediately prior to the Effective Time and which are held by a shareholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands the fair value of such shares pursuant to, and who complies in all respects with, the provisions of Article 13 of the GBCC, shall not be converted into or be exchangeable for the right to receive the Per Share Merger Consideration (the “Dissenting Shares”), but instead the holder of such Dissenting Shares (hereinafter called a “Dissenting Shareholder”) shall be entitled to payment of the fair value of such shares in accordance with the applicable provisions of the GBCC (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist and such holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of the GBCC and this Section 2.01(c)), unless and until such Dissenting Shareholder shall have failed to perfect such holder’s right to receive, or shall have effectively withdrawn or lost rights to demand or receive, the fair value of such shares of TCBC Stock under the applicable provisions of the GBCC. If any Dissenting Shareholder shall fail to perfect or effectively withdraw or lose such Holder’s dissenter’s rights under the applicable provisions of the GBCC, each such Dissenting Share shall be deemed to have been converted into and to have become exchangeable for, the right to receive the Per Share Merger Consideration, without any interest thereon, in accordance with the applicable provisions of this Agreement. TCBC shall give CBAN (i) prompt notice of any written notices to exercise dissenters’ rights in respect of any shares of TCBC Stock, attempted withdrawals of such notices and any other instruments served pursuant to the GBCC and received by TCBC relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the

5 GBCC. TCBC shall not, except with the prior written consent of CBAN, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. Any portion of the Merger Consideration made available to the Exchange Agent pursuant to this Article II to pay for shares of TCBC Stock for which dissenters’ rights have been perfected shall be returned to CBAN upon demand. If the amount paid to a Dissenting Shareholder exceeds such Dissenting Shareholder’s pro rata portion of the Merger Consideration, such excess amount shall not reduce the Per Share Merger Consideration paid to other Holders. (d) Subject to the allocation provisions of this Article II, each share of TCBC Stock (excluding Dissenting Shares and TCBC Cancelled Shares) issued and outstanding at the Effective Time shall cease to be outstanding and shall be converted, in accordance with the terms of this Article II, into and exchanged for the right to receive either: (i) a cash payment, without interest, in an amount equal to $21.25 (the “Per Share Cash Consideration”); or (ii) 1.25 (subject to adjustment as provided in Section 7.01(i), the “Exchange Ratio”) shares of CBAN Common Stock (the “Per Share Stock Consideration”). (e) If, between the date hereof and the Effective Time, the outstanding shares of CBAN Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, stock dividend, stock split, reverse stock split or similar change in capitalization, appropriate and proportionate adjustments shall be made to the Per Share Stock Consideration. (f) Notwithstanding anything to the contrary and for the avoidance of doubt, the Merger shall not be consummated unless at least 50% of the Merger Consideration shall be in the form of CBAN Common Stock. Section 2.02 Election Procedures. (a) Election. (i) Prior to the Effective Time, CBAN shall appoint an Exchange Agent, which is acceptable to TCBC in its reasonable discretion, for the payment and exchange of the Merger Consideration. (ii) Holders of record of TCBC Stock may elect to receive either shares of CBAN Common Stock or cash in exchange for their shares of TCBC Stock, provided that the aggregate number of shares of CBAN stock to be issued as Per Share Stock Consideration pursuant to this Section 2.02 shall be 3,839,748 (the “Stock Conversion Maximum”); provided, however, the Stock Conversion Maximum is subject to adjustment as provided in Section 7.01(i). (iii) An election form (“Election Form”), together with a Letter of Transmittal (as defined in Section 2.07), shall be mailed no less than twenty (20) Business Days prior to the Election Deadline (as defined below) or on such

6 earlier date as CBAN and TCBC shall mutually agree (the “Mailing Date”) to each Holder of record of TCBC Stock as of five (5) Business Days prior to the Mailing Date permitting such Holder, subject to the allocation and election procedures set forth in this Section 2.02, (1) to specify the number of shares of TCBC Stock owned by such Holder with respect to which such Holder desires to receive the Per Share Cash Consideration (a “Cash Election”, and such shares subject to a Cash Election, the “Cash Election Shares”), in accordance with the provisions of Section 2.01(d)(i), (2) to specify the number of shares of TCBC Stock owned by such Holder with respect to which such Holder desires to receive the Per Share Stock Consideration (a “Stock Election” and such shares subject to a Stock Election, the “Stock Election Shares”), in accordance with the provisions of Section 2.01(d)(ii), or (3) to indicate that such record Holder has no preference as to the receipt of cash or CBAN Common Stock for such shares. Holders of record of shares of TCBC Stock who hold such shares as nominees, trustees or in other representative capacities (a “Representative”) may submit multiple Election Forms, provided that each such Election Form covers all the shares of TCBC Stock held by each Representative for a particular beneficial owner. Any shares of TCBC Stock with respect to which the Holder thereof shall not, as of the Election Deadline (as defined in Section 2.02(a)(iv)), have made an election by submission to the Exchange Agent of an effective, properly completed Election Form shall be deemed “Non-Election Shares.” CBAN shall make available one or more Election Forms as may reasonably be requested in writing from time to time by all Persons who become holders (or beneficial owners) of TCBC Stock between the record date for the initial mailing of Election Forms and the close of business on the Business Day prior to the Election Deadline, and TCBC shall provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein. (iv) The term “Election Deadline”, as used below, shall mean 5:00 p.m., Eastern time, on the later of (1) the date of the TCBC Meeting and (2) the date that CBAN and TCBC shall agree is as near as practicable to five (5) Business Days prior to the expected Closing Date, provided, however, that the Election Deadline will automatically be extended by five (5) Business Days in the event there is any change to the Merger Consideration pursuant to Section 7.01(i). An election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline accompanied by one or more Certificates (or customary affidavits and indemnification regarding the loss or destruction of such certificates or the guaranteed delivery of such certificates) representing all the shares of TCBC Stock covered by such Election Form. Any Election Form may be revoked or changed by the Person submitting such Election Form to the Exchange Agent by written notice to the Exchange Agent only if such notice of revocation or change is actually received by the Exchange Agent at or prior to the Election Deadline. The Certificate or Certificates relating to any revoked Election Form shall be promptly returned without charge to the Person submitting the Election Form to the Exchange Agent. Shares of TCBC Stock held by holders who acquired such shares subsequent to the Election Deadline will be designated Non-Election Shares. In addition, if a Holder of TCBC Stock either (A) does not submit a properly completed Election

7 Form in a timely fashion or (B) revokes its Election Form prior to the Election Deadline and fails to file a new properly completed Election Form before the deadline, such shares shall be designated Non-Election Shares. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Election Forms, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. Neither CBAN nor the Exchange Agent shall be under any obligation to notify any Person of any defect in an Election Form. (b) Allocation. No later than five (5) Business Days after the Effective Time, CBAN shall cause the Exchange Agent to effect the allocation among Holders of TCBC Stock of rights to receive the Per Share Cash Consideration and/or the Per Share Stock Consideration, which shall be effected by the Exchange Agent as follows: (i) If the aggregate number of shares of TCBC Stock with respect to which Stock Elections shall have been made (the “Stock Election Number”) exceeds the Stock Conversion Maximum, then all Cash Election Shares and all Non-Election Shares of each Holder thereof shall be converted into the right to receive the Per Share Cash Consideration, and the Stock Election Shares of each Holder thereof will be converted into the right to receive (1) the Per Share Stock Consideration in respect of that number of Stock Election Shares equal to the product obtained by multiplying (A) the number of Stock Election Shares held by such Holder by (B) the fraction, the numerator of which is the Stock Conversion Maximum and the denominator of which is the Stock Election Number, and (2) the right to receive the Per Share Cash Consideration in respect of the remainder of such Holder’s Stock Election Shares that were not converted into the right to receive the Per Share Stock Consideration pursuant to clause (1) above. (ii) If the Stock Election Number is less than the Stock Conversion Maximum (the amount by which the Stock Conversion Maximum exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Shares shall be converted into the right to receive the Per Share Stock Consideration and the Non-Election Shares and Cash Election Shares shall be treated in the following manner: (1) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Per Share Cash Consideration and the Non-Election Shares of each Holder thereof shall be converted into the right to receive (A) the Per Share Stock Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such Holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, and (B) the right to receive the Per Share Cash Consideration in respect of the remainder of such Holder’s Non-Election Shares that were not converted into the

8 right to receive the Per Share Stock Consideration pursuant to clause (A) above; and (2) If the Shortfall Number exceeds the number of Non- Election Shares, then all Non-Election Shares shall be converted into the right to receive the Per Share Stock Consideration and the Cash Election Shares of each Holder thereof shall be converted into the right to receive (A) the Per Share Stock Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such Holder by (y) a fraction, the numerator of which is the amount by which the Shortfall Number exceeds the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, and (B) the right to receive the Per Share Cash Consideration in respect of the remainder of such Holder’s Cash Election Shares that were not converted into the right to receive the Per Share Stock Consideration pursuant to clause (A) above. Section 2.03 TCBC Stock-Based Awards. (a) Immediately prior to the Effective Time, each share of TCBC Common Stock subject to vesting restrictions granted under any TCBC Stock Plan (a “TCBC Restricted Share”) that is outstanding immediately prior to the Effective Time shall become fully vested and nonforfeitable and shall be converted automatically into and shall thereafter represent the right to receive, at the election of the Holder and subject to the allocation procedures set forth in Section 2.02(b), the Per Share Cash Consideration or the Per Share Stock Consideration, less the amount of any required withholding Tax, pursuant to Section 2.01(d). (b) At the Effective Time, each option to purchase TCBC Common Stock granted under any TCBC Stock Plan (each a “TCBC Option”), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall be cancelled and the holder thereof shall be entitled to receive from TCBC immediately prior to the Effective Time an amount in cash, without interest, equal to the product of (i) the total number of shares of TCBC Common Stock subject to such TCBC Option times (ii) the excess, if any, of the Per Share Cash Consideration over the exercise price per share of TCBC Common Stock under such TCBC Option, less applicable Taxes required to be withheld with respect to such payment. No holder of a TCBC Option that has an exercise price per share of TCBC Common Stock that is equal to or greater than the Per Share Cash Consideration shall be entitled to any payment with respect to such cancelled TCBC Option before, on, or after the Effective Time. (c) Prior to the Effective Time, the board of directors of TCBC (or, if appropriate, any committee thereof administering the TCBC Stock Plans) shall adopt such resolutions or take such other actions, including obtaining any necessary consents or amendments to the applicable award agreements and equity plans, as may be required to effectuate the provisions of this Section 2.03. Section 2.04 Rights as Shareholders; Stock Transfers. At the Effective Time, all shares of TCBC Stock, when converted in accordance with Section 2.01, shall no longer be outstanding and shall automatically be cancelled and retired and

9 shall cease to exist, and each Certificate or Book-Entry Share previously evidencing such shares shall thereafter represent only the right to receive for each such share of TCBC Stock, the Per Share Merger Consideration and any cash in lieu of fractional shares of CBAN Common Stock in accordance with this Article II. At the Effective Time, holders of TCBC Stock shall cease to be, and shall have no rights as, shareholders of TCBC, other than the right to receive the Per Share Merger Consideration and cash in lieu of fractional shares of CBAN Common Stock as provided under this Article II. At the Effective Time, the stock transfer books of TCBC shall be closed, and there shall be no registration of transfers on the stock transfer books of TCBC of shares of TCBC Stock. Section 2.05 Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of CBAN Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. In lieu thereof, CBAN shall pay or cause to be paid to each Holder who would otherwise receive a fractional share of CBAN Common Stock, rounded to the nearest one hundredth of a share, an amount of cash (without interest and rounded to the nearest whole cent) determined by multiplying the fractional share interest in CBAN Common Stock to which such Holder would otherwise be entitled by the Average Closing Price. Section 2.06 Plan of Reorganization. It is intended that the Merger and the Bank Merger shall each qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a “plan of reorganization” as that term is used in Sections 354 and 361 of the Code for each of the Merger and the Bank Merger. Section 2.07 Exchange Procedures. CBAN shall cause as promptly as practicable after the Effective Time, but in no event later than five (5) Business Days after the Closing Date, the Exchange Agent to mail or otherwise caused to be delivered to each Holder who has not previously surrendered such Certificate or Certificates or Book Entry Shares, appropriate and customary transmittal materials, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares shall pass, only upon delivery of the Certificates or Book-Entry Shares to the Exchange Agent, as well as instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the Merger Consideration (including cash in lieu of fractional shares) as provided for in this Agreement (the “Letter of Transmittal”). Section 2.08 Deposit and Delivery of Merger Consideration. (a) Prior to the Effective Time, CBAN shall (i) deposit, or shall cause to be deposited, with the Exchange Agent stock certificates representing the number of shares of CBAN Common Stock and cash sufficient to deliver the Merger Consideration (together with, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 2.05, and if applicable, cash in an aggregate amount sufficient to make the appropriate payment to the Holders of Dissenting Shares) (collectively, the “Exchange Fund”), and (ii) instruct the Exchange Agent to pay such Merger Consideration and cash in lieu of fractional shares in accordance with this

10 Agreement as promptly as practicable after the Effective Time and conditioned upon receipt of a properly completed Letter of Transmittal. The Exchange Agent and CBAN, as the case may be, shall not be obligated to deliver the Merger Consideration to a Holder to which such Holder would otherwise be entitled as a result of the Merger until such Holder surrenders the Certificates or Book-Entry Shares representing the shares of TCBC Stock for exchange as provided in this Article II, or, an appropriate affidavit of loss and indemnity agreement and/or a bond in such amount as may be reasonably required in each case by CBAN or the Exchange Agent. (b) Any portion of the Exchange Fund that remains unclaimed by the shareholders of TCBC for one (1) year after the Effective Time (as well as any interest or proceeds from any investment thereof) shall be delivered by the Exchange Agent to CBAN. Any shareholders of TCBC who have not theretofore complied with this Section 2.08 shall thereafter look only to CBAN for the Merger Consideration, any cash in lieu of fractional shares of TCBC Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such Holder is entitled in respect of each share of TCBC Stock such shareholder held immediately prior to the Effective Time, as determined pursuant to this Agreement, in each case without any interest thereon. If outstanding Certificates or Book-Entry Shares for shares of TCBC Stock are not surrendered or the payment for them is not claimed prior to the date on which such shares of CBAN Common Stock or cash would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items shall, to the extent permitted by the law of abandoned property and any other applicable Law, become the property of CBAN (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any Party shall be liable to any Holder represented by any Certificate or Book-Entry Share for any amounts delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. CBAN and the Exchange Agent shall be entitled to rely upon the stock transfer books of TCBC to establish the identity of those Persons entitled to receive the Merger Consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of any shares of TCBC Stock represented by any Certificate or Book-Entry Share, CBAN and the Exchange Agent shall be entitled to tender to the custody of any court of competent jurisdiction any Per Share Merger Consideration represented by such Certificate or Book-Entry Share and file legal proceedings interpleading all parties to such dispute, and will thereafter be relieved with respect to any claims thereto. (c) CBAN or the Exchange Agent, as applicable, shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any Holder such amounts as CBAN is required to deduct and withhold under applicable Law. Any amounts so deducted and withheld shall be remitted to the appropriate Governmental Authority and upon such remittance shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made by CBAN or the Exchange Agent, as applicable. Section 2.09 Rights of Certificate Holders after the Effective Time. (a) All shares of CBAN Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and if ever a dividend or other distribution is declared by CBAN in respect of the CBAN Common Stock, the record date for which is at or

11 after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of CBAN Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the CBAN Common Stock shall be paid to any Holder of any unsurrendered Certificate or Book-Entry Share until such Certificate or Book-Entry Share is surrendered for exchange in accordance with this Article II. Subject to the effect of applicable Laws, following surrender of any such Certificate or Book-Entry Share, there shall be issued and/or paid to the Holder of the certificates representing whole shares of CBAN Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of CBAN Common Stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of CBAN Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender. For the avoidance of doubt, Holders shall not have any right to participate in any dividends or other distributions declared by CBAN in respect of the CBAN Common Stock if the record date of such dividend or distribution is prior to the Effective Time. (b) In the event of a transfer of ownership of a Certificate representing TCBC Stock that is not registered in the stock transfer records of TCBC, the proper amount of cash and/or shares of CBAN Common Stock shall be paid or issued in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such TCBC Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a person other than the registered Holder of the Certificate or establish to the satisfaction of CBAN that the Tax has been paid or is not applicable. Section 2.10 Anti-Dilution Provisions. If the number of shares of CBAN Common Stock or TCBC Stock issued and outstanding prior to the Effective Time shall be increased or decreased, or changed into or exchanged for a different number of kind of shares or securities, in any such case as a result of a stock split, reverse stock split, stock combination, stock dividend, reclassification or similar transaction, or there shall be any extraordinary dividend or distribution with respect to such stock, and the record date therefor shall be prior to the Effective Time, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give holders of TCBC Stock the same economic effect as contemplated by this Agreement prior to such event. For the avoidance of doubt, no adjustment shall be made with regard to CBAN Common Stock if (i) CBAN issues additional shares of CBAN Common Stock and receives consideration for such shares (including, without limitation, upon the exercise of outstanding stock options or other equity awards) or (ii) CBAN issues employee or director stock grants or similar equity awards pursuant to a CBAN benefit plan.

TCBC has previously made available to CBAN true, complete and correct copies of each such TCBC Material Contract, including any and all amendments and modifications thereto. All indebtedness for borrowed money of TCBC or any of its Subsidiaries is prepayable without penalty or premium, except as set forth in TCBC Disclosure Schedule 3.12(a). (b) (i) Each TCBC Material Contract is valid and binding on TCBC and any of its Subsidiaries to the extent such Subsidiary is a party thereto, as applicable, and is in full force and effect and enforceable in accordance with its terms (assuming the due execution by each other party thereto, provided that TCBC hereby represents and warrants that, to its Knowledge, each TCBC Material Contract is duly executed by all such parties), subject to the Enforceability Exception and except where the failure to be valid, binding, enforceable and in full force and effect, individually or in the aggregate, is not reasonably likely to have a Material Adverse Effect with respect to TCBC; (ii) TCBC and each of its Subsidiaries and, to the Knowledge of TCBC, each of the other parties thereto, has in all material respects performed all obligations required to be performed by such party to date under each TCBC Material Contract; and (iii) and neither TCBC nor any of its Subsidiaries is in default under any TCBC Material Contract or other “material contract” (as such term is defined in Item 601(b)(10) of Regulation S-K of the SEC), to which it is a party, and there has not occurred any event that, with the lapse of time or the giving of notice or both, would constitute such a material default.

Subject to Section 9.11, neither TCBC nor any of its Subsidiaries is subject to any cease- and-desist or other order issued by, or is a party to any written agreement, consent agreement or memorandum of understanding with, or is a party to any commitment letter or similar undertaking to, or is a recipient of any extraordinary supervisory letter from, or is subject to any order or directive by, or has adopted any board resolutions at the request of any Governmental Authority (each a “TCBC Regulatory Agreement”) that restricts, or by its terms will in the future restrict, the conduct of TCBC’s or any of its Subsidiaries’ business or that in any manner relates to their capital adequacy, credit or risk management policies, dividend policies, management, business or operations, nor has TCBC or any of its Subsidiaries been advised by any Governmental Authority that it is considering issuing, initiating, ordering, requesting, recommending, or otherwise proceeding with (or is considering the appropriateness of any of the aforementioned actions) any TCBC Regulatory Agreement. To TCBC’s Knowledge, there are no investigations relating to any regulatory matters pending before any Governmental Authority with respect to TCBC or any of its Subsidiaries. Section 3.14 Brokers; Fairness Opinion. Neither TCBC nor any of its officers, directors or any of its Subsidiaries has employed any broker or finder or incurred, nor will it incur, any liability for any broker’s fees, commissions or finder’s fees in connection with any of the transactions contemplated by this Agreement, except that TCBC has engaged, and will pay a fee or commission to Performance Trust Capital Partners, LLC (“TCBC Financial Advisor”), in accordance with the terms of a letter agreement between TCBC Financial Advisor and TCBC, a true, complete and correct copy of which has been previously delivered by TCBC to CBAN.

Each TCBC Benefit Plan which is intended to be qualified under Section 401(a) of the Code (“TCBC 401(a) Plan”) has received a favorable determination letter from the IRS or is entitled to rely on a favorable opinion or advisory letter from the IRS, and, to TCBC’s Knowledge, there is not any circumstance that could reasonably be expected to result in revocation of any such favorable determination, opinion or advisory letter, and nothing has occurred that would be expected to result in the TCBC 401(a) Plan ceasing to be qualified under Section 401(a) of the Code. All TCBC Benefit Plans have been administered in all material respects in accordance with their terms. There is no pending or, to TCBC’s Knowledge, threatened litigation or regulatory action relating to the TCBC Benefit Plans. Neither TCBC nor any of its Subsidiaries has engaged in a transaction with respect to any TCBC Benefit Plan that could reasonably be expected to subject TCBC or any of its Subsidiaries to a tax or penalty under Section 4975 of the Code or Section 502(i) of ERISA. No TCBC 401(a) Plan has been submitted under or been the subject of an IRS voluntary compliance program submission that is still outstanding or that has not been fully corrected in accordance with a compliance statement issued by the IRS with respect to any applicable failures. There are no audits, inquiries, investigations, or proceedings pending or, to TCBC’s Knowledge, threatened by any Governmental Authority, or participant claims (other than claims for benefits in the normal course of business), with respect to any TCBC Benefit Plan. Neither TCBC nor any administrator or fiduciary of any TCBC Benefit Plan (or any agent of any of the foregoing) that is an employee of TCBC has engaged in any transaction, or acted or failed to act in any manner with respect to any TCBC Benefit Plan that could subject it to any direct or indirect material liability (by indemnity or otherwise) for breach of any fiduciary, co-fiduciary, or other duty under ERISA.

TCBC has not contributed to (or been obligated to contribute to) a “multiple employer

24 plan” within the meaning of ERISA Sections 4063 or 4064 or Code Section 413(c) at any time. Neither TCBC nor any of its Subsidiaries or ERISA Affiliates have incurred, and there are no circumstances under which they could reasonably be expected to incur, liability under Title IV of ERISA. Neither TCBC nor any of its Subsidiaries has ever sponsored, maintained or participated in a multiple employer welfare arrangement as defined in ERISA Section 3(40).

(f) Except as set forth in TCBC Disclosure Schedule 3.15(f), no TCBC Benefit Plan provides life insurance, medical, surgical, hospitalization or other employee welfare benefits to any TCBC Employee, upon or following his or her retirement or termination of employment for any reason, except as may be required by Law.

TCBC may amend or terminate any such TCBC Benefit Plan at any time. (h) Except as otherwise provided for in this Agreement or as set forth in TCBC Disclosure Schedule 3.15(h), neither the execution of this Agreement, shareholder approval of this Agreement or consummation of any of the transactions contemplated by this Agreement (individually or in conjunction with any other event) will (i) entitle any TCBC Employee to retention or other bonuses, parachute payments, non-competition payments, or any other payment, (ii) entitle any TCBC Employee to severance pay or any increase in severance pay, (iii) accelerate the time of payment or vesting (except as required by Law) or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under or increase the amount payable any of the TCBC Benefit Plans, (iv) result in any breach or violation of, or a default under, any of the TCBC Benefit Plans, (v) result in any payment of any amount that would, individually or in combination with any other such payment, be an excess “parachute payment” to a “disqualified individual” as those terms are defined in Section 280G of the Code, or (vi) limit or restrict the right of TCBC or, after the consummation of the transactions contemplated hereby, CBAN or any of its Subsidiaries, to merge, amend or terminate any of the TCBC Benefit Plans. (i) Except as set forth in TCBC Disclosure Schedule 3.15(i), each TCBC Benefit Plan that is a non-qualified deferred compensation plan or arrangement within the meaning of Section 409A of the Code, and any underlying award, is in compliance in all material respects with Section 409A of the Code.

As of the date of this Agreement, no executive officer of CBAN has failed in any respect to make the certifications required of him or her under Section 302 or 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act.

Subject to Section 9.11, there is no unresolved violation, criticism or exception by any Governmental Authority with respect to any report filed by, or relating to any examinations or inspections by any such Governmental Authority of CBAN or any of its Subsidiaries which would reasonably be likely to have, either individually or in the aggregate, a Material Adverse Effect with respect to CBAN.

(a) Each of CBAN and TCBC shall call, give notice of, convene and hold a meeting of its shareholders (the “CBAN Meeting” and the “TCBC Meeting,” respectively) as soon as reasonably practicable (subject to applicable notice requirements) after the Registration Statement is declared effective for the purpose of obtaining the Requisite CBAN Shareholder Approval and the Requisite TCBC Shareholder Approval required in connection with this Agreement and the Merger and, if so desired and mutually agreed, upon other matters of the type customarily brought before an annual or special meeting of shareholders to approve a merger agreement or the issuance of shares contemplated thereby (as applicable). The board of directors of each of CBAN and TCBC shall use its commercially reasonable efforts to obtain from the shareholders of CBAN and TCBC, as the case may be, the Requisite CBAN Shareholder Approval, in the case of CBAN, and the Requisite TCBC Shareholder Approval, in the case of TCBC, including by communicating to its respective shareholders its recommendation (and including such recommendation in the Proxy Statement/Prospectus) that they approve this Agreement and the transactions contemplated hereby, including, with respect to CBAN, the CBAN Common Stock Issuance. CBAN or TCBC shall adjourn or postpone the CBAN Meeting or the TCBC Meeting, as the case may be, if, as of the time for which such meeting is originally scheduled there are insufficient shares of CBAN Common Stock or the TCBC Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting CBAN or TCBC as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite CBAN Shareholder Approval or the Requisite TCBC Shareholder Approval. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, each of the CBAN Meeting and TCBC Meeting shall be convened, the CBAN Common Stock Issuance shall be submitted to the shareholders of CBAN, and this Agreement shall be submitted to the shareholders of TCBC, at the CBAN Meeting and TCBC Meeting, respectively, for the purpose of voting on the approval of such proposals and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve

54 either CBAN or TCBC of such obligation.

In the event that there is present at such meeting, in person or by proxy, sufficient favorable voting power to secure the Requisite TCBC Shareholder Approval, TCBC will not adjourn or postpone the TCBC Meeting unless TCBC is advised by counsel that failure to do so would result in a breach of the fiduciary duties of the board of directors of TCBC. TCBC shall keep CBAN updated with respect to the proxy solicitation results in connection with the TCBC Meeting as reasonably requested by CBAN. (c) The board of directors of CBAN shall at all times prior to and during the CBAN Meeting recommend approval of the CBAN Common Stock Issuance by the shareholders of CBAN and any other matters required to be approved by CBAN’s shareholders for the CBAN Common Stock Issuance (the “CBAN Recommendation”) and shall not withhold, withdraw, amend, modify, change or qualify such recommendation in a manner adverse in any respect to the interests of TCBC or take any other action or make any other public statement inconsistent with such recommendation and the Proxy Statement-Prospectus shall include such recommendation. In the event that there is present at such meeting, in person or by proxy, sufficient favorable voting power to secure the Requisite CBAN Shareholder Approval, CBAN will not adjourn or postpone the CBAN Meeting unless CBAN is advised by counsel that failure to do so would result in a breach of the fiduciary duties of the board of directors of CBAN. CBAN shall keep TCBC updated with respect to the proxy solicitation results in connection with the CBAN Meeting as reasonably requested by TCBC. Section 5.05 Registration Statement; Proxy Statement-Prospectus; NYSE Listing. (a) CBAN and TCBC agree to cooperate in the preparation of the Registration Statement. TCBC shall use its reasonable best efforts to deliver to CBAN such financial statements and related analysis of TCBC, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of TCBC, as may be required in order to file the Registration Statement, and any other report required to be filed by CBAN with the SEC, in each case, in compliance in all material respects with applicable Laws, and shall, as promptly as practicable following execution of this Agreement, prepare and deliver drafts of such information to CBAN to review. Subject to TCBC’s cooperation as provided in this Section 5.05(a), within forty-five (45) days of the date of this Agreement, CBAN shall file with the SEC the Registration Statement. Each of CBAN and TCBC agree to use their respective commercially reasonable efforts to cause the Registration Statement to be declared effective by the SEC as promptly as reasonably

55 practicable after the filing thereof and to maintain such effectiveness for as long as necessary to consummate the Merger and the other transactions contemplated by this Agreement. CBAN also agrees to use commercially reasonable efforts to obtain any necessary state securities Law or “blue sky” permits and approvals required to carry out the transactions contemplated by this Agreement. TCBC agrees to cooperate with CBAN and CBAN’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from TCBC’s independent auditors in connection with the Registration Statement and the Proxy Statement-Prospectus. After the Registration Statement is declared effective under the Securities Act, TCBC, at its own expense, shall promptly mail or cause to be mailed the Proxy Statement-Prospectus to its shareholders. (b) CBAN will advise TCBC, promptly after CBAN receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of CBAN Common Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or upon the receipt of any comments (whether written or oral) from the SEC or its staff. CBAN will provide TCBC and its counsel with a reasonable opportunity to review and comment on the Registration Statement and the Proxy Statement-Prospectus, and all responses to requests for additional information by and replies to comments of the SEC prior to filing such with, or sending such to, the SEC, and CBAN will provide TCBC and its counsel with a copy of all such filings made with the SEC. If at any time prior to the Effective Time there shall occur any event that should be disclosed in an amendment or supplement to the Proxy Statement-Prospectus or the Registration Statement so that either such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, CBAN shall use its commercially reasonable efforts to promptly prepare and file such amendment or supplement with the SEC (if required under applicable Law) and cooperate with TCBC to mail such amendment or supplement to TCBC shareholders (if required under applicable Law). (c) CBAN will use its commercially reasonable efforts to cause the shares of CBAN Common Stock to be issued in connection with the transactions contemplated by this Agreement to be approved for listing on NYSE, subject to official notice of issuance, prior to the Effective Time. Section 5.06 Regulatory Filings; Consents. (a) Each of CBAN and TCBC and their respective Subsidiaries shall cooperate and use their respective reasonable best efforts (i) to promptly prepare all documentation (including the Registration Statement and the Proxy Statement-Prospectus), and to effect all filings, to obtain all permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary to consummate the transactions contemplated by this Agreement, the Regulatory Approvals and all other consents and approvals of a Governmental Authority required to consummate the Merger in the manner contemplated herein, (ii) to comply with the terms and conditions of such permits, consents, approvals and authorizations and (iii) to cause the transactions contemplated by this Agreement to be consummated as expeditiously as practicable; provided, however, notwithstanding the foregoing or anything to the contrary in this Agreement, nothing contained herein shall be deemed to require CBAN or any of its Subsidiaries or TCBC or

56 any of its Subsidiaries to take any non-standard action, or commit to take any such action, or agree to any non-standard condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of any Governmental Authority that would reasonably be likely to have a material and adverse effect (measured on a scale relative to TCBC) on the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties or business of CBAN, TCBC, the Surviving Entity or the Surviving Bank, after giving effect to the Merger (“Burdensome Condition”). CBAN and TCBC will furnish each other and each other’s counsel with all information concerning themselves, their Subsidiaries, directors, trustees, officers and shareholders and such other matters as may be necessary or advisable in connection with any application, petition or any other statement or application made by or on behalf of CBAN or TCBC to any Governmental Authority in connection with the transactions contemplated by this Agreement. Each Party shall have the right to review and approve in advance all characterizations of the information relating to such party and any of its Subsidiaries that appear in any filing made in connection with the transactions contemplated by this Agreement with any Governmental Authority. In addition, CBAN and TCBC shall each furnish to the other for review a copy of each non-confidential portion of such filing made in connection with the transactions contemplated by this Agreement with any Governmental Authority prior to its filing. (b) TCBC will use its commercially reasonable efforts, and CBAN shall reasonably cooperate with TCBC at TCBC’s request, to obtain all consents, approvals, authorizations, waivers or similar affirmations described on TCBC Disclosure Schedule 3.12(c) or that are otherwise required to be obtained under the terms of any TCBC Material Contract in order to prevent the consummation of the transactions contemplated by this Agreement from constituting a default under such TCBC Material Contract or creating any lien, claim, or charge upon any of the assets of TCBC or any of its Subsidiaries. Each Party will notify the other Party promptly and shall promptly furnish the other Party with copies of notices or other communications received by such Party or any of its Subsidiaries of any communication from any Person alleging that the consent of such Person (or another Person) is or may be required in connection with the transactions contemplated by this Agreement (and the response thereto from such Party, its Subsidiaries or its representatives). TCBC will consult with CBAN and its representatives as often as practicable under the circumstances so as to permit TCBC and CBAN and their respective representatives to cooperate to take appropriate measures to obtain such consents and avoid or mitigate any adverse consequences that may result from the foregoing. Section 5.07 Publicity. CBAN and TCBC shall consult with each other before issuing any press release with respect to this Agreement or the transactions contemplated hereby and shall not issue any such press release or make any such public statement without the prior consent of the other Party, which shall not be unreasonably delayed or withheld; provided, however, that a party may, without the prior consent of the other party (but after such consultation, to the extent practicable in the circumstances), issue such press release or make such public statements as may upon the advice of counsel be required by Law or the rules and regulations of any stock exchanges. It is understood that CBAN shall assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Merger and the other transactions contemplated hereby.

57 Section 5.08 Access; Current Information. (a) For the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, upon reasonable notice and subject to applicable Laws, TCBC agrees to afford CBAN and its officers, employees, counsel, accountants and other authorized representatives such access during normal business hours at any time and from time to time throughout the period prior to the Effective Time to TCBC’s and its Subsidiaries’ books, records (including, without limitation, Tax Returns and work papers of independent auditors), information technology systems, business, properties and personnel and to such other information relating to them as CBAN may reasonably request and TCBC shall use its commercially reasonable efforts to provide any appropriate notices to employees and/or customers in accordance with applicable Law and TCBC’s privacy policy and, during such period, TCBC shall furnish to CBAN, upon CBAN’s reasonable request, all such other information concerning the business, properties and personnel of TCBC and its Subsidiaries that is substantially similar in scope to the information provided to CBAN in connection with its diligence review prior to the date of this Agreement. Within thirty (30) days of the date of this Agreement, TCBC will furnish to CBAN true and complete copies of all deeds and other documentation evidencing ownership of the real properties set forth in TCBC Disclosure Schedule Section 3.30(a), and complete copies of the title insurance policies and surveys for each property, together with any mortgages, deeds of trust, and security agreements to which such property is subject. (b) For the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, during the period of time from the date of this Agreement to the Effective Time, upon reasonable notice and subject to applicable Laws, CBAN agrees to furnish to TCBC such information as TCBC may reasonably request concerning the business of CBAN and its Subsidiaries that is substantially similar in scope to the information provided to TCBC in connection with its diligence review prior to the date of this Agreement. (c) As promptly as reasonably practicable after they become available, TCBC will furnish to CBAN copies of the board packages distributed to the board of directors of TCBC or any of its Subsidiaries, and minutes from the meetings thereof, copies of any internal management financial control reports showing actual financial performance against plan and previous period, and copies of any reports provided to the board of directors of TCBC or any committee thereof relating to the financial performance and risk management of TCBC.

Without limiting the foregoing, TCBC agrees to provide to CBAN (i) to the extent permitted by applicable Law, a copy of each report filed by TCBC or any of its Subsidiaries with a Governmental Authority, (ii) a copy of TCBC’s monthly loan trial balance, and (iii) a copy of TCBC’s monthly statement of condition and profit and loss statement and, if requested by CBAN, a copy of TCBC’s daily statement of condition and daily profit and loss statement, in each case, which shall be provided as promptly as reasonably practicable after it is filed or prepared, as applicable.

(e) No investigation by a Party or its representatives shall be deemed to modify or waive any representation, warranty, covenant or agreement of the other Party set forth in this Agreement, or the conditions to the respective obligations of CBAN and TCBC to consummate the transactions contemplated hereby. (f) Notwithstanding anything to the contrary in this Section 5.08, no Party shall be required to provide the other Party with any documents that disclose confidential discussions of this Agreement or the transactions contemplated hereby, that contain competitively sensitive business or other proprietary information filed under a claim of confidentiality (including any confidential supervisory information) or any other matter that a Party’s board of directors has been advised by counsel that such distribution to the other Party may violate a confidentiality obligation or fiduciary duty or any Law or regulation, or may result in a waiver of such Party’s attorney-client privilege. In the event any of the restrictions in this Section 5.08(f) shall apply, such Party shall use its commercially reasonable efforts to provide appropriate consents, waivers, decrees and approvals necessary to satisfy any confidentiality issues relating to documents prepared or held by third parties (including work papers), and the Parties will make appropriate alternate disclosure arrangements, including adopting additional specific procedures to protect the confidentiality of sensitive material and to ensure compliance with applicable Laws. Section 5.09 No Solicitation by TCBC; Superior Proposals. (a) Except as permitted by Section 5.09(b), TCBC shall not, and shall cause its Subsidiaries and each of their respective officers, directors and employees not to, and will not authorize any investment bankers, financial advisors, attorneys, accountants, consultants, affiliates or other agents of TCBC or any of TCBC’s Subsidiaries (collectively, the “TCBC Representatives”) to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal; (ii) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any Person (other than CBAN) any information or data with respect to TCBC or any of its Subsidiaries or otherwise relating to an Acquisition Proposal; (iii) release any Person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which TCBC is a party; or (iv) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal. Any violation of the foregoing restrictions by any of the TCBC Representatives, whether or not such TCBC Representative is so authorized and whether or not such TCBC Representative is purporting to act on behalf of TCBC or otherwise, shall be deemed to be a breach of this Agreement by TCBC. TCBC and its Subsidiaries shall, and shall cause each of the TCBC Representatives to, immediately cease and cause to be terminated any and all existing

59 discussions, negotiations, and communications with any Persons with respect to any existing or potential Acquisition Proposal. For purposes of this Agreement, “Acquisition Proposal” means any inquiry, offer or proposal (other than an inquiry, offer or proposal from CBAN), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction. For purposes of this Agreement, “Acquisition Transaction” means (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving TCBC or any of its Subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, a significant portion of the assets of TCBC or any of its Subsidiaries; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing 20% or more of the votes attached to the outstanding securities of TCBC or any of its Subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 20% or more of any class of equity securities of TCBC or any of its Subsidiaries; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing. For purposes of this Agreement, “Superior Proposal” means a bona fide, unsolicited Acquisition Proposal (i) that if consummated would result in a third party (or in the case of a direct merger between such third party and TCBC or any of its Subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than 50% of the outstanding TCBC Stock or more than 50% of the assets of TCBC and its Subsidiaries, taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of TCBC reasonably determines in good faith, after consultation with its outside financial advisor and outside legal counsel, (A) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the person making such Acquisition Proposal, and (B) taking into account any changes to this Agreement proposed by CBAN in response to such Acquisition Proposal, as contemplated by Section 5.09(c), and all financial, legal, regulatory and other aspects of such takeover proposal, including all conditions contained therein and the person making such proposal, is more favorable to the shareholders of TCBC from a financial point of view than the Merger. (b) Notwithstanding Section 5.09(a) or any other provision of this Agreement, prior to the date of the TCBC Meeting, TCBC may take any of the actions described in Section 5.09(a) if, but only if, (i) TCBC has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of Section 5.09(a); (ii) the board of directors of TCBC reasonably determines in good faith, after consultation with and having considered the advice of its outside financial advisor and outside legal counsel, that (A) such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) it is reasonably necessary to take such actions to comply with its fiduciary duties to TCBC’s shareholders under applicable Law; (iii) TCBC has provided CBAN with at least three (3) Business Days’ prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with

60 respect to TCBC or any of its Subsidiaries or otherwise relating to an Acquisition Proposal, TCBC receives from such Person a confidentiality agreement with terms no less favorable to TCBC than those contained in the confidentiality agreement with CBAN. TCBC shall promptly provide to CBAN any non-public information regarding TCBC or its Subsidiaries provided to any other Person which was not previously provided to CBAN, such additional information to be provided no later than the date of provision of such information to such other party. (c) TCBC shall promptly (and in any event within twenty-four (24) hours) notify CBAN in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, TCBC or the TCBC Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the Person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications) except to the extent that such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement). TCBC agrees that it shall keep CBAN informed, on a reasonably current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request). (d) Neither the board of directors of TCBC nor any committee thereof shall (i) withdraw, qualify, amend or modify, or propose to withdraw, qualify, amend or modify, in a manner adverse to CBAN in connection with the transactions contemplated by this Agreement (including the Merger), the TCBC Recommendation, fail to reaffirm the TCBC Recommendation within three (3) Business Days following a request by CBAN, or make any statement, filing or release, in connection with the TCBC Meeting or otherwise, inconsistent with the TCBC Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the TCBC Recommendation); (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iii) enter into (or cause TCBC or any of its Subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any Acquisition Transaction (other than a confidentiality agreement entered into in accordance with the provisions of Section 5.09(b)) or (B) requiring TCBC to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement. (e) Notwithstanding Section 5.09(d), prior to the date of the TCBC Meeting, the board of directors of TCBC may withdraw, qualify, amend or modify the TCBC Recommendation (a “TCBC Subsequent Determination”) after the fifth (5th) Business Day following CBAN’s receipt of a notice (the “Notice of Superior Proposal”) from TCBC advising CBAN that the board of directors of TCBC has decided (in good faith after consultation with its outside legal counsel and financial advisor) that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of Section 5.09(a)) constitutes a Superior Proposal if, but only if, (i) the board of directors of TCBC has determined in good faith, after consultation with and having considered the advice of outside legal counsel and its financial advisor, that it is reasonably necessary to take such actions to comply with its fiduciary duties to TCBC’s shareholders under applicable Law, (ii) during the five (5) Business Day period after receipt of the Notice of Superior

61 Proposal by CBAN (the “Notice Period”), TCBC and the board of directors of TCBC shall have cooperated and negotiated in good faith with CBAN to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable TCBC to proceed with the TCBC Recommendation without a TCBC Subsequent Determination; provided, however, that CBAN shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement and (iii) at the end of the Notice Period, after taking into account any such adjusted, modified or amended terms as may have been proposed by CBAN since its receipt of such Notice of Superior Proposal, the board of directors of TCBC has again in good faith made the determination (A) in clause (i) of this Section 5.09(e) and (B) that such Acquisition Proposal constitutes a Superior Proposal. In the event of any material revisions to the Superior Proposal, TCBC shall be required to deliver a new Notice of Superior Proposal to CBAN and again comply with the requirements of this Section 5.09(e), except that the Notice Period shall be reduced to three (3) Business Days. (f) Notwithstanding any TCBC Subsequent Determination, this Agreement shall be submitted to TCBC’s shareholders at the TCBC Meeting for the purpose of voting on the approval of this Agreement and the transactions contemplated hereby (including the Merger) and nothing contained herein shall be deemed to relieve TCBC of such obligation; provided, however, that if the board of directors of TCBC shall have made a TCBC Subsequent Determination with respect to a Superior Proposal, then the board of directors of TCBC may recommend approval of such Superior Proposal by the shareholders of TCBC and may submit this Agreement to TCBC’s shareholders without recommendation, in which event the board of directors of TCBC shall communicate the basis for its recommendation of such Superior Proposal and the basis for its lack of a recommendation with respect to this Agreement and the transactions contemplated hereby to TCBC’s shareholders in the Proxy Statement-Prospectus or an appropriate amendment or supplement thereto. (g) Nothing contained in this Section 5.09 shall prohibit TCBC or the board of directors of TCBC from complying with TCBC’s obligations required under Rule 14e-2(a) promulgated under the Exchange Act; provided, however, that any such disclosure relating to an Acquisition Proposal (other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed a change in the TCBC Recommendation unless the board of directors of TCBC reaffirms the TCBC Recommendation in such disclosure. Section 5.10 Indemnification. (a) For a period of six (6) years from and after the Effective Time, and in any event subject to the provisions of Section 5.10(c), CBAN shall indemnify and hold harmless the present and former directors and officers of TCBC and its Subsidiaries (each an “Indemnified Party”), against all costs, expenses (including reasonable attorney’s fees), judgments, fines, losses, claims, damages or liabilities or amounts that are paid in settlement (which settlement shall require the prior written consent of CBAN, which consent shall not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (each a “Claim”), arising out of actions or omissions of such persons in the course of performing their duties for TCBC or any of its Subsidiaries occurring at or before the Effective Time (including the Merger and the other transactions contemplated

62 hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the same extent permitted under the organizational documents of TCBC and its Subsidiaries in effect on the date of this Agreement to the extent permitted by applicable Law; provided, however, that that notwithstanding anything to the contrary contained in the organizational documents of the TCBC or its Subsidiaries, CBAN shall have no obligation to provide indemnification under this paragraph (a) to any Indemnified Party for any Excluded Claim. (b) In connection with the indemnification provided pursuant to Section 5.09(g), CBAN and/or an CBAN Subsidiary will advance expenses, promptly after statements therefor are received, to each TCBC Indemnified Party, to the same extent permitted under the organizational documents of TCBC and its Subsidiaries in effect on the date of this Agreement to the extent permitted by applicable Law (provided the individual to whom expenses are advanced provides an undertaking to repay such advance if it is ultimately determined that such individual is not entitled to indemnification), including the payment of the fees and expenses of one counsel with respect to a matter, and one local counsel in each applicable jurisdiction, if necessary or appropriate, selected by such TCBC Indemnified Party or multiple Indemnified Parties, it being understood that they collectively shall only be entitled to one counsel and one local counsel in each applicable jurisdiction where necessary or appropriate (unless a conflict shall exist between them in which case they may retain separate counsel), all such counsel shall be reasonably satisfactory to CBAN. CBAN shall have no obligation to advance expenses related to any Excluded Claim. (c) Any Indemnified Party wishing to claim indemnification under this Section 5.09(g) shall promptly notify CBAN upon learning of any Claim, provided that, failure to so notify shall not affect the obligation of CBAN under this Section 5.09(g), unless, and only to the extent that, CBAN is materially prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether asserted or claimed prior to, at or after the Effective Time), (i) CBAN shall have the right to assume the defense thereof and CBAN shall not be liable to such Indemnified Parties for any legal expenses or other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) CBAN shall not be liable for any settlement effected without its prior written consent, and (iv) CBAN shall have no obligation hereunder to any Indemnified Party if such indemnification would be in violation of any applicable federal or state banking Laws or regulations, or in the event that a federal or state banking agency or a court of competent jurisdiction shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws and regulations, whether or not related to banking Laws. (d) For a period of six (6) years following the Effective Time, CBAN will maintain director’s and officer’s liability insurance (herein, “D&O Insurance”) that serves to reimburse the present and former officers and directors of TCBC or its Subsidiaries (determined as of the Effective Time) with respect to claims against such directors and officers arising from facts or events occurring before the Effective Time (including the transactions contemplated hereby), which insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the Indemnified Party, as that coverage currently provided by TCBC; provided that, if CBAN is unable to maintain or obtain the insurance called for by this Section 5.09(g), CBAN will provide as much comparable insurance as is reasonably available (subject to the limitations described below in this Section 5.10(d)); and provided, further, that

63 officers and directors of TCBC or its Subsidiaries may be required to make application and provide customary representations and warranties to the carrier of the D&O Insurance for the purpose of obtaining such insurance. In no event shall CBAN be required to expend for such tail insurance a premium amount in excess of an amount equal to 200% of the annual premiums paid by TCBC for D&O Insurance in effect as of the date of this Agreement (the “Maximum D&O Tail Premium”). If the cost of such tail insurance exceeds the Maximum D&O Tail Premium, CBAN shall obtain tail insurance coverage or a separate tail insurance policy with the greatest coverage available for a cost not exceeding the Maximum D&O Tail Premium. (e) Any indemnification payments made pursuant to this Error! Reference source not found. are subject to and conditioned upon their compliance with Section 18(k) of the Federal Deposit Insurance Act (12 U.S.C. § 1828(k)) and the regulations promulgated by the FDIC (12 C.F.R. Part 359). (f) This Section 5.09(g) shall survive the Effective Time, is intended to benefit each TCBC Indemnified Party (each of whom shall be entitled to enforce this Section against CBAN), and shall be binding on all successors and assigns of CBAN. (g) If CBAN or any of its successors and assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) shall transfer all or substantially all of its property and assets to any individual, corporation or other entity, then, in each such case, proper provision shall be made so that the successors and assigns of CBAN and its Subsidiaries shall assume the obligations set forth in this Section 5.09(g). Section 5.11 Employees; Benefit Plans. (a) Following the Effective Time, for a period of six (6) months, CBAN shall maintain or cause to be maintained employee benefit plans for the benefit of employees who are full time employees of TCBC on the Closing Date and who become employees of CBAN in connection with the transaction contemplated hereunder (“Covered Employees”) that provide employee benefits which, in the aggregate, are substantially comparable to the employee benefits and cash- based compensation opportunities that are made available on a uniform and non-discriminatory basis to similarly situated employees of CBAN; provided, however, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of CBAN. CBAN shall give the Covered Employees credit for their prior service with TCBC for purposes of eligibility (including initial participation and eligibility for current benefits) and vesting under any employee benefit plan maintained by CBAN and in which Covered Employees may be eligible to participate. (b) With respect to any employee benefit plan of CBAN that is a health, dental, vision or other welfare plan in which any Covered Employee is eligible to participate, for the plan year that includes the Closing, if Covered Employees are eligible to participate in such plans, CBAN shall use its commercially reasonable efforts to cause any pre-existing condition limitations, eligibility waiting periods or evidence of insurability requirements under such CBAN plan to be waived with respect to such Covered Employee and his or her covered dependents to the extent such condition was or would have been covered under the comparable TCBC Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time.

64 (c) Following the Effective Time, Colony Bank shall credit each Covered Employee with an amount of paid time off equal to such Covered Employee’s accrued but unused paid time off at TC Federal Bank (“Carryover PTO”); provided, however, that such Carryover PTO will be forfeited if not used in accordance with the terms of Colony Bank’s policies. (d) TCBC shall cause TC Federal Bank to take all necessary actions to terminate the TC Federal Bank 401(k) Plan (the “401(k) Plan”), effective as the date immediately preceding the date of the Effective Time of the Merger, subject to the occurrence of the Effective Time. TCBC shall provide CBAN with copies of the appropriate resolutions terminating the plan not later than three (3) days prior to the Effective Time. The accounts of all participants and beneficiaries in the 401(k) Plan shall become fully vested upon termination of such plan.

TCBC will provide CBAN for review and comment, reasonably in advance of the ESOP Vote, all materials proposed to be distributed to the ESOP participants in connection with the ESOP Vote. CBAN shall have five business days to review and provide comments with respect to the materials to be distributed to ESOP participants with respect to the ESOP Vote.

(h) Prior to the Effective Time, TCBC shall take, and shall cause TC Federal Bank to take, all actions requested by CBAN that may be necessary or appropriate to, conditioned on the occurrence of the Effective Time, (i) cause one or more TCBC Benefits Plans not covered above to terminate as of the Effective Time, or as of the date immediately preceding the Effective Time, (ii) cause benefit accruals and entitlements under any TCBC Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any TCBC Benefit Plan for such period as may be requested by CBAN, or (iv) facilitate the merger of any TCBC Benefit Plan into any employee benefit plan maintained by CABN. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Error! Reference source not found.(h) shall be subject to CBAN’s reasonable prior review and approval, which shall not be unreasonably withheld, conditioned or delayed.

65 (i) Except for employees whose terms of employment are governed by the CBAN Employment Agreements, any employee of TCBC or TC Federal Bank that becomes an employee of CBAN or Colony Bank at the Effective Time who is terminated within one year following the Effective Time (other than for cause, death, disability, normal retirement or voluntarily resignation) shall receive a severance payment calculated in accordance with the policy set forth on CBAN Disclosure Schedule 5.11(i)Section 5.11(i).

This Agreement represents the entire understanding of the Parties and thereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made. Except for the Indemnified Parties’ rights under Section 5.09(g), CBAN and TCBC hereby agree that their respective representations, warranties and covenants set forth herein are solely for the benefit of the other Party, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person (including any person or employees who might be affected by Section 5.11), other than the Parties, any rights or remedies hereunder, including, the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations between the Parties and are for the sole benefit of the Parties. Consequently, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date. Section 9.07 Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the Parties will use their commercially reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

No item is required to be set forth in either the TCBC Disclosure Schedule or the CBAN Disclosure Schedule as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect. The mere inclusion of an item in either Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by either party 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, or that any breach or violation of applicable Laws or any contract exists or has actually occurred. This Agreement shall not be interpreted or construed to require any person to take any action, or fail to take any action, if to do so would violate any applicable Law. (d) Any reference contained in this Agreement to specific statutory or regulatory provisions or to any specific Governmental Authority shall include any successor statute or regulation, or successor Governmental Authority, as the case may be. Unless the context clearly indicates otherwise, the masculine, feminine, and neuter genders will be deemed to be interchangeable, and the singular includes the plural and vice versa.

(e) Unless otherwise specified, the references to “Section” and “Article” in this Agreement are to the Sections and Article of this Agreement. When used in this Agreement, words such as “herein”, “hereinafter”, “hereof”, “hereto”, and “hereunder” refer to this Agreement as a whole, unless the context clearly requires otherwise. Section 9.10 Assignment. No Party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other Party, and any purported assignment in violation of this Section 9.10 shall be void. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns.

Section 3. No Transfers. Until the earlier of (a) the termination of this Agreement pursuant to Section 7 and (b) receipt of the Requisite TCBC Shareholder Approval, Shareholder agrees not to, directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any of the Shares, except the following transfers shall be permitted: (i) transfers by will or operation of Law, in which case this Agreement shall bind the transferee, (ii) transfers pursuant to any pledge agreement, subject to the pledgee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement, (iii) transfers

Any transfer or other disposition in violation of the terms of this Section 3 shall be null and void; provided, however, the pledges disclosed in Schedule A that are in effect as of the date hereof to a lender of the undersigned, and bona fide transactions under such pledges are permitted.

Section 4. Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with CBAN as follows: (a) Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement. (b) This Agreement has been duly executed and delivered by ▇▇▇▇▇▇▇▇▇▇▇, and assuming the due authorization, execution and delivery by CBAN, constitutes a valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. (c) The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject or, in the event that Shareholder is a corporation, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder. (d) Shareholder is the beneficial owner of, or is the trustee that is the record holder of, and whose beneficiaries are the beneficial owners of, and has good title to all of the Shares, and, except for pledges set forth on Schedule A, the Shares are owned free and clear of any liens, security interests, charges or other encumbrances. The Shares do not include shares over which Shareholder exercises control in a fiduciary capacity for any other person or entity that is not an Affiliate of Shareholder, and no representation by Shareholder is made with respect thereto. Shareholder has the right to vote, or direct the voting of, the Shares, and none of the Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement. Shareholder does not own, of record or beneficially, any shares of capital stock of TCBC other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock.

5 Section 5. No Solicitation. From and after the date hereof until the termination of this Agreement pursuant to Section 7, Shareholder, in his, her or its capacity as a shareholder of TCBC, shall not, nor shall such Shareholder authorize any partner, officer, director, advisor or representative of, such Shareholder or any of his, her or its Affiliates to, directly or indirectly (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to prohibit any of his, her or its representatives or Affiliates to), (a) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (b) except in his capacity as a director or officer of TCBC and under circumstances for which such actions are permitted for TCBC under the Merger Agreement, participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any person (other than CBAN) any information or data with respect to TCBC or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle or letter of intent with respect to an Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal, (d) solicit proxies with respect to an Acquisition Proposal (other than the Merger Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement, or (e) initiate a shareholders’ vote or action by consent of TCBC’s shareholders with respect to an Acquisition Proposal. Section 6. Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of CBAN to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to CBAN if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, CBAN will not have an adequate remedy at law or in equity. Accordingly, ▇▇▇▇▇▇▇▇▇▇▇ agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that CBAN has an adequate remedy at Law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with CBAN’s seeking or obtaining such equitable relief. In addition, after discussing the matter with Shareholder, CBAN shall have the right to inform any third party that CBAN reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of CBAN hereunder, and that participation by any such persons with Shareholder in activities in violation of Shareholder’s agreement with CBAN set forth in this Agreement may give rise to claims by CBAN against such third party. Section 7. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the mutual written agreement of the parties hereto, and shall be automatically terminated upon the earlier to occur of (a) the Effective Time, (b) the amendment of the Merger Agreement in any manner that materially and adversely affects any of Shareholder’s rights set forth therein (including, for the avoidance of doubt, any reduction to the Merger Consideration), (c) termination of the Merger Agreement or (d) three (3) years from the date hereof. Upon such termination, no party shall have any further

6 obligations or liabilities hereunder; provided, however, that such termination shall not relieve any party from liability for any breach of this Agreement prior to such termination. Section 8. Entire Agreement. This Agreement represents the entire understanding of the parties hereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made. Section 9. Modification and Waiver. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by each party. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of dissimilar provisions or conditions at the same or any prior subsequent time. Section 10. Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the parties shall use their commercially reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement. Section 11. Capacity as Shareholder. This Agreement shall apply to Shareholder solely in his, her or its capacity as a shareholder of TCBC and it shall not apply in any manner to Shareholder in his, her or its capacity as a director or officer of TCBC or a fiduciary of any trust in which Shareholder is not the sole beneficiary, if applicable. Nothing contained in this Agreement shall be deemed to apply to, limit or otherwise affect in any manner, the obligations of Shareholder to comply with his, her or its fiduciary duties as a director or office of TCBC or a fiduciary of any trust in which Shareholder is not the sole beneficiary, if applicable. Section 12. Governing Law. This Agreement shall be governed by, and interpreted and enforced in accordance with, the internal, substantive laws of the State of Georgia, without regard for conflict of law provisions.

Each party consents to the jurisdiction of such Georgia court in any such civil action, counterclaim, proceeding or litigation and waives any objection to the laying of venue of any such civil action, counterclaim, proceeding or litigation in such Georgia court. Service of any court paper may be effected on such party by mail, as provided in this letter, or in such other manner as may be provided under applicable Laws. Section 14. WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY

7 LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

From time to time prior to the termination of this Agreement, at CBAN’s request and without further consideration, Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the transactions contemplated by this Agreement. Shareholder further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against CBAN, Colony Bank, TCBC, TC Federal Bank or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger.

EXHIBIT D FORM OF NON-COMPETITION AND NON-DISCLOSURE AGREEMENT This Non-Competition and Non-Disclosure Agreement (the “Agreement”), is dated as of July 23, 2025, by and between the undersigned director of TC Bancshares, Inc. (“Director”), and Colony Bankcorp, Inc., a Georgia corporation (“CBAN”). All capitalized terms used but not defined herein shall have the meanings assigned to them in the Merger Agreement (defined below). RECITALS: WHEREAS, concurrently with the execution of this Agreement, CBAN and TC Bancshares, Inc., a Georgia corporation (“TCBC”), are entering into an Agreement and Plan of Merger (as such agreement may be subsequently amended or modified, the “Merger Agreement”), pursuant to which (a) TCBC will merge with and into CBAN, with CBAN as the surviving entity, and (b) TC Federal Bank, a federal savings association and a direct wholly-owned subsidiary of TCBC, will merge with and into Colony Bank, a Georgia state-chartered bank and a direct wholly- owned subsidiary of CBAN, with Colony Bank as the surviving bank (collectively, the “Merger”); WHEREAS, Director is a shareholder of TCBC and, as a result of the Merger and pursuant to the transactions contemplated by the Merger Agreement, Director is expected to receive significant consideration in exchange for the shares of TCBC Stock held by Director; WHEREAS, as of and prior to the date hereof, Director serves and has served as a member of the Board of Directors of TCBC or TC Federal Bank, and, therefore, Director has knowledge of the Confidential Information and Trade Secrets (each as hereinafter defined); WHEREAS, as a result of the Merger, CBAN will succeed to all of the Confidential Information and Trade Secrets, for which CBAN as of the Effective Time will have paid valuable consideration and desires reasonable protection; and WHEREAS, it is a material prerequisite to the consummation of the Merger that each director of TCBC and TC Federal Bank, including Director, enter into this Agreement. AGREEMENT: NOW, THEREFORE, in consideration of these premises and the mutual covenants and undertakings herein contained, CBAN and Director, each intending to be legally bound, covenant and agree as follows: Section 1. Restrictive Covenants. (a) Director acknowledges that (i) CBAN has separately bargained for the restrictive covenants in this Agreement; and (ii) the types and periods of restrictions imposed by the covenants in this Agreement are fair and reasonable to Director and such restrictions will not prevent Director from earning a livelihood.

3 (b) Having acknowledged the foregoing, solely in the event that the Merger is consummated, Director covenants and agrees with CBAN as follows: (i) From and after the date hereof, Director shall maintain in strict confidence and shall not, directly or indirectly, disclose, use or permit the use of any Confidential Information or Trade Secrets for so long as such information remains Confidential Information or a Trade Secret, as applicable, for any purpose, except for any disclosure that is required by applicable Law. In the event that Director is required by Law to disclose any Confidential Information, Director will: (A) if and to the extent permitted by such Law, provide CBAN with prompt notice of such requirement prior to the disclosure so that CBAN may waive the requirements of this Agreement or seek an appropriate protective order at CBAN’s sole expense; however, Director will cooperate fully with CBAN in seeking such protective measures and (B) use commercially reasonable efforts to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment. If, in the absence of a waiver or protective order, Director is nonetheless, in the opinion of his or her counsel, required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that counsel advises Director is required to be disclosed, and Director shall use its reasonable best efforts to ensure that such disclosed Confidential Information is accorded confidential treatment. (ii) Except as expressly provided on Schedule I to this Agreement, for a period beginning on the date hereof and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of CBAN), on Director’s own behalf or in the service or on behalf of others, solicit or attempt to solicit any customer of CBAN, Colony Bank, TCBC or TC Federal Bank (each a “Protected Party”), including actively sought prospective customers of TC Federal Bank as of the Effective Time, for the purpose of providing products or services that are Competitive (as hereinafter defined) with those offered or provided by any Protected Party, provided that the foregoing will not prevent the placement of any general solicitation not specifically targeted towards customers of any Protected Party or providing products or services as a result thereof. This restriction shall apply regardless of whether the customer relationship was established prior to or after the Effective Time. (iii) Except as expressly provided on Schedule I to this Agreement, for a period beginning on the date hereof and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of CBAN), either directly or indirectly, on Director’s own behalf or in the service or on behalf of others, act as a director, manager, officer or employee of any business which offers products or services that are Competitive and which has an office located within the Restricted Territory (as hereinafter defined). (iv) For a period beginning on the date hereof and ending two (2) years after the Effective Time, Director will not, on Director’s own behalf or in the service or on behalf of others, solicit or recruit or attempt to solicit or recruit,

4 directly or by assisting others, any employee of any Protected Party, whether or not such employee is a full-time employee or a temporary employee of such Protected Party, whether or not such employment is pursuant to a written agreement and whether or not such employment is for a determined period or is at will, to cease working for such Protected Party; provided that the foregoing will not prevent the placement of any general solicitation for employment not specifically directed towards employees of any Protected Party or hiring any such person as a result thereof. (c) For purposes of this Section 1, the following terms shall be defined as set forth below: (i) “Competitive,” with respect to particular products or services, means products or services that are the same as or similar to the products or services of any Protected Party. (ii) “Confidential Information” means data and information: (A) relating to the business of TCBC and its Subsidiaries, including TC Federal Bank, regardless of whether the data or information constitutes a Trade Secret; (B) disclosed to Director or of which Director became aware as a consequence of Director’s relationship with TCBC and/or TC Federal Bank; (C) having value to TCBC and/or TC Federal Bank and, as a result of the consummation of the transactions contemplated by the Merger Agreement, CBAN and/or Colony Bank; and (D) not generally known to competitors of TCBC or CBAN (including competitors to TC Federal Bank or Colony Bank). Confidential Information shall include Trade Secrets, methods of operation, names of customers, price lists, financial information and projections, personnel data and similar information; provided, however, that the terms “Confidential Information” and “Trade Secrets” shall not mean data or information that (x) has been disclosed to the public, except where such public disclosure has been made by Director without authorization from TCBC or CBAN, (y) has been independently developed and disclosed by others, or (z) has otherwise entered the public domain through lawful means. (iii) “Restricted Territory” means each county in Georgia and Florida where TC Federal Bank operates a banking office at the Effective Time and each county contiguous of each of such counties. (iv) “Trade Secret” means information, without regard to form, including technical or nontechnical data, a formula, a pattern, a compilation, a

5 program, a device, a method, a technique, a drawing, a process, financial data, financial plans, product plans or a list of actual or potential customers or suppliers, that is not commonly known by or available to the public and which information: (A) derives economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use; and (B) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy. (d) Director acknowledges that irreparable loss and injury would result to CBAN upon the breach of any of the covenants contained in this Section 1 and that damages arising out of such breach would be difficult to ascertain. Director ▇▇▇▇▇▇ agrees that, in addition to all other remedies provided at law or in equity, CBAN may petition and obtain from a court of law or equity, without the necessity of proving actual damages and without posting any bond or other security, both temporary and permanent injunctive relief to prevent a breach by Director of any covenant contained in this Section 1, and shall be entitled to an equitable accounting of all earnings, profits and other benefits arising out of any such breach. In the event that the provisions of this Section 1 should ever be determined to exceed the time, geographic or other limitations permitted by applicable Law, then such provisions shall be modified so as to be enforceable to the maximum extent permitted by Law. If such provision(s) cannot be modified to be enforceable, the provision(s) shall be severed from this Agreement to the extent unenforceable. The remaining provisions and any partially enforceable provisions shall remain in full force and effect. Section 2. Term and Termination. This Agreement may be terminated at any time by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon the earlier of (a) termination of the Merger Agreement prior to the consummation of the Merger or; (ii) two (2) years following the Effective Time. For the avoidance of doubt, the provisions of Section 1 shall only become operative upon the consummation of the Merger but, in such event, shall survive the consummation of the Merger until the earlier of (a) two (2) years after the Effective Time or (b) upon a Change in Control of CBAN. Upon termination of this Agreement, no party shall have any further obligations or liabilities hereunder, except that termination of this Agreement will not relieve a breaching party from liability for any breach of any provision of this Agreement occurring prior to the termination of this Agreement. Section 3. Notices. All notices, requests and other communications hereunder to a party shall be in writing and shall be deemed properly given if delivered (a) personally, (b) by registered or certified mail (return receipt requested), with adequate postage prepaid thereon, (c) by properly addressed electronic mail delivery (with confirmation of delivery receipt) or (d) by reputable courier service to such party at its address set forth below, or at such other address or addresses as such party may specify from time to time by notice in like manner to the parties hereto. All notices shall be deemed effective upon delivery.
