The Bank Merger shall become effective immediately following the Effective Time or at such later time and date as specified in the Bank Merger Agreement in accordance with applicable law (the “Bank Merger Effective Time”).

1.2 Closing. Pursuant to the terms and subject to the conditions of this Agreement, the closing of the Merger (the “Closing”) will take place by electronic exchange of documents at 10:00 a.m., Eastern time, on a date which shall be no later than three Business Days after the satisfaction or waiver (subject to applicable law) of all of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by IBTX and SouthState. The date on which the Closing occurs is referred to as the “Closing Date.”
1.3 Effective Time. On or (if agreed by IBTX and SouthState) prior to the Closing Date, SouthState and IBTX, respectively, shall cause to be filed a certificate of merger with the Secretary of State of the State of Texas (the “Texas Secretary”) in accordance with the TBOC and articles of merger with the Secretary of State of the State of South Carolina (the “South Carolina Secretary”) in accordance with the SCBCA (collectively, the “Certificates of Merger”).

(a)Subject to Section 2.2(e), each share of the common stock, par value $0.01 per share, of IBTX (the “IBTX Common Stock”) issued and outstanding immediately prior to the Effective Time, except for shares of IBTX Common Stock owned by IBTX or SouthState (in each case, other than shares of IBTX Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties, or (ii) held, directly or indirectly, by IBTX or SouthState in respect of debts previously contracted), shall be converted into the right to receive 0.60 shares (the “Exchange Ratio”; and such shares, the “Merger Consideration”) of the common stock, par value $2.50 per share, of SouthState (the “SouthState Common Stock”); it being understood that at and after the

3

​

​

Effective Time, pursuant to Section 1.6, the SouthState Common Stock, including the shares issued to former holders of IBTX Common Stock, shall be the common stock of the Surviving Entity.
(b)All of the shares of IBTX Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, an “Old Certificate”; it being understood that any reference herein to “Old Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of IBTX Common Stock) previously representing any such shares of IBTX Common Stock shall thereafter represent only the right to receive (i) a New Certificate (as defined below) representing the number of whole shares of SouthState Common Stock that such shares of IBTX Common Stock have been converted into the right to receive, (ii) cash in lieu of fractional shares which the shares of IBTX Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to this Section 1.5 and Section 2.2(e), without any interest thereon, and (iii) any dividends or distributions that the holder thereof has the right to receive pursuant to Section 2.2, in each case, without any interest thereon. If, prior to the Effective Time, the outstanding shares of SouthState Common Stock or IBTX 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, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar structural change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio to give SouthState and the holders of IBTX Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing contained in this sentence shall be construed to permit IBTX or SouthState to take any action with respect to its securities or otherwise that is prohibited by the terms of this Agreement.
(c)Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of IBTX Common Stock that are owned by IBTX or SouthState (in each case, other than shares of IBTX Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties, or (ii) held, directly or indirectly, by IBTX or SouthState in respect of debts previously contracted) shall be cancelled and shall cease to exist and no SouthState Common Stock or other consideration shall be delivered in exchange therefor.
1.6 SouthState Stock. At and after the Effective Time, each share of SouthState Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Entity and shall not be affected by the Merger.
1.7 Treatment of IBTX Equity Awards.
(a)At the Effective Time, each outstanding restricted stock award with respect to shares of IBTX Common Stock (a “IBTX Restricted Share Award”) shall, automatically and without any required action on the part of the holder thereof, be fully vested, canceled and converted into the right to receive a number of shares of SouthState Common Stock equal to the product (rounded to the nearest whole number) of (x) the number of shares of IBTX Common

4

​

​

Stock subject to such IBTX Restricted Share Award immediately prior to the Effective Time multiplied by (y) the Exchange Ratio.
(b)At the Effective Time, each outstanding performance restricted stock unit award with respect to shares of IBTX Common Stock (a “IBTX PSU Award”) shall, automatically and without any required action on the part of the holder thereof, be fully vested, canceled and converted into the right to receive (i) a number of shares of SouthState Common Stock equal to the product (rounded to the nearest whole number) of (x) the number of shares of IBTX Common Stock subject to such IBTX PSU Award immediately prior to the Effective Time based on the higher of target performance and actual performance through the Effective Time as reasonably determined by the compensation committee of the Board of Directors of IBTX (the “IBTX Compensation Committee”) multiplied by (y) the Exchange Ratio, plus (ii) a cash payment in respect of any accrued but unpaid dividend equivalents on such IBTX PSU Award.
(c)At or prior to the Effective Time, IBTX, the Board of Directors of IBTX and the IBTX Compensation Committee, as applicable, shall adopt any resolutions and take any actions that are necessary or appropriate to effectuate the provisions of this Section 1.7.
(d)SouthState shall take all corporate actions that are necessary for the treatment of the IBTX Restricted Share Awards and IBTX PSU Awards (together, the “IBTX Equity Awards”) pursuant to Sections 1.7(a) and 1.7(b), including the reservation, issuance and listing of SouthState Common Stock as necessary to effect the transactions contemplated by this Section 1.7. SouthState shall issue the consideration contemplated by this Section 1.7, less any applicable Taxes required to be withheld in respect of such consideration, as promptly as practicable following the Effective Time (but in no event later than two (2) Business Days after the Closing Date).
1.8 Articles of Incorporation of Surviving Entity. At the Effective Time, the articles of incorporation of SouthState, as in effect immediately prior to the Effective Time, shall be the articles of incorporation of the Surviving Entity until thereafter amended in accordance with the terms thereof and applicable law.
1.9 Bylaws of Surviving Entity. At the Effective Time, the bylaws of SouthState, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Entity until thereafter amended in accordance with the terms thereof and applicable law.
1.10 Tax Consequences. It is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a plan of reorganization for the purposes of Sections 354 and 361 of the Code.
Article II
EXCHANGE OF SHARES
2.1 SouthState to Make Consideration Available. At or prior to the Effective Time, SouthState shall deposit, or shall cause to be deposited, with an exchange agent mutually agreed upon by SouthState and IBTX (the “Exchange Agent”), for exchange in accordance with

5

​

​

this Article II for the benefit of the holders of Old Certificates, certificates or, at SouthState’s option, evidence in book-entry form, representing shares of SouthState Common Stock to be issued pursuant to Section 1.5 (collectively, referred to herein as “New Certificates”), and cash in lieu of any fractional shares to be paid pursuant to Section 2.2(e) (such cash and New Certificates, together with any dividends or distributions with respect to shares of SouthState Common Stock payable in accordance with Section 2.2(b), being referred to as the “Exchange Fund”).
2.2 Exchange of Shares.
(a)As promptly as practicable after the Effective Time, but in no event later than five Business Days thereafter, the Surviving Entity shall cause the Exchange Agent to mail to each holder of record of one or more Old Certificates representing shares of IBTX Common Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive SouthState Common Stock pursuant to Article I, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates representing the number of whole shares of SouthState Common Stock and any cash in lieu of fractional shares, which the shares of IBTX Common Stock represented by such Old Certificate or Old Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b) (such materials and instructions to include customary provisions with respect to delivery of an “agent’s message” with respect to any book-entry shares). Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent (it being understood that no certificates shall be required to be delivered for shares of IBTX Common Stock held in book-entry form at the Effective Time), together with such properly completed and duly executed letter of transmittal, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, as applicable, (i) a New Certificate representing that number of whole shares of SouthState Common Stock to which such holder of IBTX Common Stock shall have become entitled pursuant to the provisions of Article I, and (ii) a check representing the amount of (x) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II, and (y) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares or dividends or distributions payable to holders of Old Certificates. Until surrendered as contemplated by this Section 2.2, each Old Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the number of whole shares of SouthState Common Stock which the shares of IBTX Common Stock represented by such Old Certificate have been converted into the right to receive and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.
(b)No dividends or other distributions declared with respect to SouthState Common Stock shall be paid to the holder of any unsurrendered Old Certificate until the holder thereof shall surrender such Old Certificate in accordance with this Article II. After the surrender of an Old Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore

​

​

had become payable with respect to the whole shares of SouthState Common Stock that the shares of IBTX Common Stock represented by such Old Certificate have been converted into the right to receive.
(c)If any New Certificate representing shares of SouthState Common Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a New Certificate representing shares of SouthState Common Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.
(d)After the Effective Time, there shall be no transfers on the stock transfer books of IBTX of the shares of IBTX Common Stock. If, after the Effective Time, Old Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for New Certificates representing shares of SouthState Common Stock, cash in lieu of fractional shares and dividends or distributions as contemplated by this Section 2.2, as applicable.
(e)Notwithstanding anything to the contrary contained in this Agreement, no New Certificates or scrip representing fractional shares of SouthState Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to SouthState Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of SouthState. In lieu of the issuance of any such fractional share, the Surviving Entity shall pay to each former holder of IBTX Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of SouthState Common Stock on the New York Stock Exchange (the “NYSE”) as reported by The Wall Street Journal for the consecutive period of five full trading days ending on the trading day immediately preceding the Closing Date (or, if not reported therein, in another authoritative source mutually agreed upon by IBTX and SouthState) by (ii) the fraction of a share (after taking into account all shares of IBTX Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest one-thousandth when expressed in decimal form) of SouthState Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.
(f)Any portion of the Exchange Fund that remains unclaimed by the shareholders of IBTX for 12 months after the Effective Time shall be paid to the Surviving Entity. Any former holders of IBTX Common Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Entity for payment of the shares of SouthState Common Stock, cash in lieu of any fractional shares and any unpaid dividends and distributions

​

on the SouthState Common Stock deliverable in respect of each former share of IBTX Common Stock such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of SouthState, IBTX, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of shares of IBTX Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by former holders of shares of IBTX Common Stock immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Entity shall, to the extent permitted by applicable law, become the property of the Surviving Entity, free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.
(g)The Surviving Entity shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any cash in lieu of fractional shares of SouthState Common Stock, cash dividends or distributions payable pursuant to this Section 2.2 or any other amounts otherwise payable pursuant to this Agreement to any holder of IBTX Common Stock or IBTX Equity Awards, such amounts as it is required to deduct and withhold with respect to the making of such payment or distribution under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so deducted or withheld by the Surviving Entity or the Exchange Agent, as the case may be, and paid over to the appropriate Governmental Entity, the deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of IBTX Common Stock or IBTX Equity Awards in respect of which the deduction and withholding was made by the Surviving Entity or the Exchange Agent, as the case may be.
(h)In the event any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if required by the Surviving Entity or the Exchange Agent, the posting by such person of a bond in such amount as the Surviving Entity or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the shares of SouthState Common Stock and any cash in lieu of fractional shares, and dividends or distributions, deliverable in respect thereof pursuant to this Agreement.

Except (a) as disclosed in the disclosure schedule delivered by IBTX to SouthState concurrently herewith (the “IBTX Disclosure Schedule”) (it being understood that (i) no item is required to be set forth 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, (ii) the mere inclusion of an item in the IBTX Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by IBTX that such item represents a material exception or fact, event or circumstance or that such item would reasonably be expected to have a Material Adverse Effect, and (iii) any disclosures made with respect to a section of this Article III shall be deemed to qualify (1) any other section of this Article III specifically referenced or cross-

8

​

​

referenced, and (2) any other sections of this Article III to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure applies to such other sections), or (b) as disclosed in any IBTX Reports publicly filed with or furnished to the SEC by IBTX since December 31, 2021 and prior to the date hereof (but disregarding risk factor disclosures contained under the heading “Risk Factors,” or disclosures of risks set forth in any “forward-looking statements” disclaimer or any other statements that are similarly cautionary, predictive or forward-looking in nature; provided that this clause (b) shall not apply to the representations and warranties set forth in Sections ‎3.1(a), ‎3.2(a), ‎3.3(a), ‎3.3(b)(i), ‎3.7 and 3.22), IBTX hereby represents and warrants to SouthState as follows:

3.1 Corporate Organization.
(a)IBTX is a corporation duly organized, validly existing and in good standing under the laws of the State of Texas, is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”), and has not elected to be treated as a financial holding company under the BHC Act. IBTX has the corporate power and authority to own, lease or operate all of its properties and assets and to carry on its business as it is now being conducted in all material respects. IBTX is duly licensed or qualified to do business and in good standing (to the extent such concept (or a similar concept) exists in such jurisdiction) in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, leased or operated by it makes such licensing, qualification or standing necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on IBTX. As used in this Agreement, the term “Material Adverse Effect” means, with respect to SouthState, IBTX or the Surviving Entity, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (i) the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements (and, in either case, any authoritative interpretations thereof), (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, (D) changes, after the date hereof, resulting from hurricanes, earthquakes, tornados, naturally-occurring floods or other natural disasters or from any outbreak of any disease, pandemic, epidemic or other public health event, (E) public disclosure of the execution of this Agreement, public disclosure or consummation of the transactions contemplated hereby (including any effect on a party’s relationships with its customers or employees) or actions expressly required by this Agreement or that are taken with the prior written consent of the other party in contemplation of the transactions contemplated hereby (it being understood that this Clause (E) shall not apply to a breach of any representation or warranty intended to address the announcement, pendency or consummation of the transactions contemplated hereby) or (F) a decline in the trading price of a

9

​

​

party’s common stock in and of itself or the failure, in and of itself, to meet earnings projections or internal financial forecasts (it being understood that the underlying causes of such decline or failure may be taken into account in determining whether a Material Adverse Effect has occurred, except to the extent otherwise excepted by this proviso); except, with respect to subclauses (A), (B), (C) or (D) to the extent that the effects of such change are materially disproportionately adverse to the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its Subsidiaries operate) or (ii) the ability of such party to timely consummate the transactions contemplated hereby. As used in this Agreement, the term “Subsidiary” when used with respect to any person, means any subsidiary of such person as defined in Rule 1-02(x) of Regulation S-X promulgated by the SEC or the BHC Act. True and complete copies of the amended and restated certificate of formation of IBTX, as amended (the “IBTX Certificate”), and the sixth amended and restated bylaws of IBTX (the “IBTX Bylaws”), in each case, as in effect as of the date of this Agreement, have previously been made available by IBTX to SouthState.
(b)Except as would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on IBTX, each Subsidiary of IBTX (a “IBTX Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly licensed or qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership, leasing or operation of property or the conduct of its business requires it to be so licensed or qualified or in good standing, and (iii) has all requisite corporate power and authority to own, lease or operate its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of IBTX or any Subsidiary of IBTX to pay dividends or distributions except, in the case of IBTX or a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all similarly regulated entities. IBTX Bank is the only depository institution Subsidiary of IBTX, and the deposit accounts of IBTX Bank are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund (as defined in Section 3(y) of the Federal Deposit Insurance Act of 1950 (the “FDI Act”)) to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened. Section 3.1(b) of the IBTX Disclosure Schedule sets forth a true, correct and complete list of all Subsidiaries of IBTX as of the date hereof. No Subsidiary of IBTX is in violation of any of the provisions of its articles or certificate of incorporation or bylaws (or comparable organizational documents). True and complete copies of the organizational documents of IBTX Bank as in effect as of the date of this Agreement have previously been made available by IBTX to SouthState. There is no person whose results of operations, cash flows, changes in shareholders’ equity or financial position are consolidated in the financial statements of IBTX other than the IBTX Subsidiaries.

All the issued and outstanding shares of IBTX Common Stock have been duly authorized and validly issued and are fully paid, nonassessable and free of preemptive rights, with no personal liability attaching to the ownership thereof. As of the date hereof, no trust preferred or subordinated debt securities of IBTX are issued or outstanding except as set forth on Section 3.2(a) of the IBTX Disclosure Schedule.

Other than IBTX Equity Awards, no equity or equity-based awards (including any cash awards where the amount of payment is determined, in whole or in part, based on the price of any capital stock of IBTX or any of its Subsidiaries) are outstanding. No IBTX Subsidiary owns any capital stock of IBTX. There are no voting trusts, shareholder agreements, proxies or other agreements in effect to which IBTX or any of its Subsidiaries is a party with respect to the voting or transfer of IBTX Common Stock, capital stock or other voting or equity securities or ownership interests of IBTX or granting any shareholder or other person any registration rights.
(b)Except as would not, either individually or in the aggregate, reasonably be expected to be material to IBTX, IBTX owns, directly or indirectly, all the issued and outstanding shares of capital stock or other equity ownership interests of each of the IBTX Subsidiaries, free and clear of any liens, claims, title defects, mortgages, pledges, charges, and security interests whatsoever, and any other encumbrances securing a payment or the performance of an obligation (collectively, “Liens”), and all of such shares or equity ownership interests are duly authorized and validly issued and are fully paid, nonassessable (except, with respect to Subsidiaries that are depository institutions, as provided under any provision of applicable state law comparable to 12 U.S.C. § 55) and free of preemptive rights, with no personal liability attaching to the ownership thereof.

This Agreement has been duly and validly executed and delivered by IBTX and (assuming due authorization, execution and delivery by SouthState) constitutes a valid and binding obligation of IBTX, enforceable against IBTX in accordance with its terms (except in all cases as such enforceability may be limited by bankruptcy, insolvency, moratorium, reorganization or similar laws of general applicability affecting the rights of creditors generally and the availability of equitable remedies (the “Enforceability Exceptions”)).
(b)Neither the execution and delivery of this Agreement by IBTX nor the consummation by IBTX of the transactions contemplated hereby (including the Merger and the Bank Merger), nor compliance by IBTX with any of the terms or provisions hereof, will (i) violate any provision of the IBTX Certificate, the IBTX Bylaws or the organizational documents of any

As used herein, “Applicable Agencies” means the United States Department of Agriculture and the Small Business Administration.
3.5 Reports. IBTX and each of its Subsidiaries have timely filed (or furnished) all reports, forms, correspondence, registrations and statements, together with any amendments required to be made with respect thereto, that they were required to file (or furnish, as applicable) since December 31, 2021 with (a) any state regulatory authority, (b) the SEC, (c) the Federal Reserve Board, (d) the FDIC, (e) any foreign regulatory authority, and (f) any self-regulatory organization (an “SRO”) (clauses (a) – (f), collectively “IBTX Regulatory Agencies”, and together with the SouthState Regulatory Agencies, the “Regulatory Agencies”), including any report, form, correspondence, registration or statement required to be filed (or furnished, as applicable) pursuant to the laws, rules or regulations of the United States, any state, any foreign entity or any IBTX Regulatory Agency, and have paid all fees and assessments due and payable in connection therewith, except where the failure to file (or furnish, as applicable) such report, form, correspondence, registration or statement or to pay such fees and assessments, either individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on IBTX. As of their respective dates, such reports, forms, correspondence, registrations and statements, and other filings, documents and instruments were complete and accurate and complied with all applicable laws, in each case, except as would not reasonably be expected to, either individually or in the aggregate, have a Material Adverse Effect on IBTX. Subject to Section 9.14, except for normal examinations conducted by a IBTX Regulatory Agency in the ordinary course of business of IBTX and its Subsidiaries, no IBTX Regulatory Agency or governmental agency or authority has initiated or has pending any proceeding or, to the knowledge of IBTX, investigation into the business or operations of IBTX or any of its Subsidiaries since December 31, 2021, except where such proceedings or investigations would not reasonably be expected to, either individually or in the aggregate, have a Material Adverse Effect on IBTX.

3.6 Financial Statements.
(a)The financial statements of IBTX and its Subsidiaries included (or incorporated by reference) in the IBTX Reports (including the related notes, where applicable) (i) have been prepared from, and are in accordance with, the books and records of IBTX and its Subsidiaries in all material respects, (ii) fairly present in all material respects the consolidated results of operations, cash flows, changes in shareholders’ equity and consolidated financial position of IBTX and its Subsidiaries for the respective fiscal periods or as of the respective dates

14

​

​

therein set forth (subject in the case of unaudited statements to year-end audit adjustments normal in nature and amount), (iii) complied, as of their respective dates of filing with the SEC, in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto, and (iv) have been prepared in accordance with GAAP consistently applied during the periods involved, except, in each case, as indicated in such statements or in the notes thereto. Since December 31, 2021, no independent public accounting firm of IBTX has resigned (or informed IBTX that it intends to resign) or been dismissed as independent public accountants of IBTX as a result of or in connection with any disagreements with IBTX on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.
(b)Except as would not reasonably be expected to, either individually or in the aggregate, have a Material Adverse Effect on IBTX, neither IBTX nor any of its Subsidiaries has any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due), except for those liabilities that are reflected or reserved against on the consolidated balance sheet of IBTX included in its Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024 (including any notes thereto) and for liabilities incurred in the ordinary course of business consistent with past practice since March 31, 2024, or in connection with this Agreement and the transactions contemplated hereby.
(c)The records, systems, controls, data and information of IBTX and its Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership of IBTX or its Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership that would not reasonably be expected to have a Material Adverse Effect on IBTX. IBTX (x) has implemented and maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) to ensure that material information relating to IBTX, including its Subsidiaries, is made known to the chief executive officer and the chief financial officer of IBTX by others within those entities as appropriate to allow timely decisions regarding required disclosures and to make the certifications required by the Exchange Act and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to IBTX’s outside auditors and the audit committee of IBTX’s Board of Directors (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to adversely affect IBTX’s ability to record, process, summarize and report financial information, and (ii) to the knowledge of IBTX, any fraud, whether or not material, that involves management or other employees who have a significant role in IBTX’s internal controls over financial reporting. To the knowledge of IBTX, any such disclosures were made in writing by management to IBTX’s auditors and audit committee and true, correct and complete copies of such disclosures have been made available by IBTX to SouthState. As of the date hereof, neither IBTX nor its independent audit firm has identified, and, to the knowledge of IBTX, no circumstances exist upon which IBTX or its independent audit firm would reasonably be expected to identify after the date hereof, any un-remediated material weakness in internal controls over financial reporting or disclosure controls and procedures. To the knowledge of IBTX, there is no reason to believe that IBTX’s outside auditors and its chief executive officer and chief financial officer will not be able to give the certifications and

15

​

SouthState shall also use its reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions contemplated by this Agreement, and IBTX shall furnish all information concerning IBTX and the holders of IBTX Common Stock as may be reasonably requested in connection with any such action.
(b)The parties hereto shall cooperate with each other and use their reasonable best efforts to (i) promptly prepare and file all necessary documentation, to effect all applications,

55

​

​

notices, petitions and filings (and in the case of the applications, notices, petitions and filings in respect of the Requisite Regulatory Approvals, use their reasonable best efforts to make such filings within 45 days of the date of this Agreement) and (ii) obtain as promptly as practicable all permits, consents, waivers, approvals and authorizations of all third parties and Governmental Entities which are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger and the Bank Merger), and to comply with the terms and conditions of all such permits, consents, waivers, approvals and authorizations of all such Regulatory Agencies and Governmental Entities. IBTX and SouthState shall each use, and shall each cause their applicable Subsidiaries to use, reasonable best efforts to obtain each such Requisite Regulatory Approval as promptly as reasonably practicable. SouthState and IBTX shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case, subject to applicable laws relating to the exchange of information, all the information relating to IBTX or SouthState, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. The parties hereto agree that they will consult with each other with respect to obtaining all permits, consents, waivers, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated in this Agreement, and each party shall consult with the other in advance of any meeting or conference with any Governmental Entity in connection with the transactions contemplated by this Agreement and, to the extent permitted by such Governmental Entity, give the other party and/or its counsel the opportunity to attend and participate in such meetings and conferences, in each case subject to applicable law; and provided, that each party shall promptly advise the other party with respect to substantive matters that are addressed in any meeting or conference with any Governmental Entity which the other party does not attend or participate in connection with or affecting the transactions contemplated by this Agreement, to the extent permitted by such Governmental Entity and subject to applicable law and Section 9.14. As used in this Agreement, the term “Requisite Regulatory Approvals” shall mean all regulatory authorizations, consents, waivers, orders and approvals (and the expiration or termination of all statutory waiting periods in respect thereof) (i) from the OCC and the Federal Reserve Board (in respect of the Merger or the Bank Merger) or (ii) referred to in Section 3.4 or Section 4.4 that are necessary to consummate the transactions contemplated by this Agreement (including the Merger and the Bank Merger), except, in the case of this clause (ii), for any such authorizations, consents, waivers, orders or approvals the failure of which to be obtained would not be material to the Surviving Entity.
(c)In furtherance and not in limitation of the foregoing, each party shall use its reasonable best efforts to avoid the entry of, or to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that would restrain, prevent or delay the Closing. Notwithstanding the foregoing, nothing contained in this Agreement shall be deemed to require SouthState or IBTX or any of their respective Subsidiaries, and neither IBTX nor any of its Subsidiaries shall be permitted (without the prior written consent of SouthState), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, waivers, approvals and authorizations of Governmental Entities that would reasonably be expected to have

56

​

​

a material adverse effect on the Surviving Entity and its Subsidiaries, taken as a whole, after giving effect to the Merger (provided that for purposes of determining whether any of the foregoing gives rise to such a “material adverse effect”, “material adverse effect” shall be measured on a scale relative only to the size of IBTX and its Subsidiaries, taken as a whole, without SouthState and its Subsidiaries) (a “Materially Burdensome Regulatory Condition”).
(d)SouthState and IBTX shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Joint Proxy Statement, the S-4 or any other statement, filing, notice or application made by or on behalf of SouthState, IBTX or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement.
(e)SouthState and IBTX shall promptly advise each other upon receiving any communication from any Governmental Entity whose permit, consent, waiver, approval or authorization is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained, or that the receipt of any such permit, consent, waiver, approval or authorization will be materially delayed.
(f)Notwithstanding anything to the contrary in this Agreement, SouthState shall be entitled to direct the defense of the transactions contemplated by this Agreement before any Governmental Entity and to control the scheduling of, and strategic planning for, any meetings with, and the conducting of negotiations with, Governmental Entities regarding any Requisite Regulatory Approvals consistent with this Section 6.1, so long as SouthState shall consult with IBTX and its counsel reasonably in advance regarding the matters described in this Section 6.1, and consider in good faith all recommendations of IBTX and its counsel.
6.2 Advisory Client Consents.
(a)IBTX shall, and shall cause each RIA Subsidiary to, use its reasonable best efforts to obtain, as promptly as reasonably practicable after the date of this Agreement in accordance with applicable law and the applicable Advisory Agreement, the consent of each Advisory Client to the deemed assignment of its Advisory Agreement as a result of the transactions contemplated hereby prior to Closing (such consent, “Client Consent”). Without limiting the generality of the foregoing, each RIA Subsidiary shall send, at least 60 days prior to Closing, notices to each Advisory Client as of the date hereof (i) informing such Advisory Client of the transactions contemplated hereby, (ii) informing such Advisory Client that such RIA Subsidiary intends to continue to provide Investment Advisory Services to such Advisory Client after the Closing and requesting such Advisory Client’s consent thereto, (iii) requesting the requisite consent of such Advisory Client to such deemed assignment and (iv), unless the Advisory Client’s Advisory Agreement requires the Advisory Client’s written consent to such deemed assignment, informing such Advisory Client that the consent of such Advisory Client will be deemed to have been provided if such Advisory Client does not notify in writing the applicable RIA Subsidiary of its objection to such deemed assignment, or of its termination of its Advisory Agreement, within sixty (60) days after the sending of such notice. At the end of such forty-five day period, if such Advisory Client has not provided written notice to the applicable RIA Subsidiary of such objection

57

​

​

or termination, such Advisory Client shall be deemed to have provided its Client Consent for all purposes under this Agreement. In the case of a person who becomes an Advisory Client during the period from the date of this Agreement through the Closing (a “New Client”), the Client Consent of such New Client shall be deemed to have been provided for all purposes hereunder, if the relevant RIA Subsidiary provides such New Client with disclosure prior to the entering into of its Advisory Agreement (A) informing such New Client of the transactions contemplated hereby, (B) informing such New Client that such RIA Subsidiary intends to continue to provide Investment Advisory Services to such New Client after Closing, and (C) informing such New Client that the consent of such New Client will be deemed to have been provided by the entering in to by such New Client of its Advisory Agreement. SouthState shall have a reasonable opportunity to review and comment on all materials used to seek Client Consents, or disclose the transactions contemplated hereby to New Clients, for purposes of this ‎Section 6.2(a) prior to distribution. IBTX agrees to cause the RIA Subsidiary to cooperate with and support IBTX’s efforts under this ‎Section 6.2(a).
(b)Each party hereto shall reasonably cooperate in connection with obtaining the approvals and consents sought pursuant to this Section 6.2. Each party shall cause all information relating to such party and its Affiliates supplied by it for inclusion in such requests for approvals and consents contemplated by this Section 6.2, at the time of the mailing or delivery of such requests for approvals and consents or supplemental communications related thereto, to not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.
6.3 Access to Information; Confidentiality.
(a)Upon reasonable notice and subject to applicable laws, each of IBTX and SouthState, for the purposes of enabling SouthState and IBTX to verify the representations and warranties of the other party and preparing for the Mergers and the other matters contemplated by this Agreement, shall, and shall cause its Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors and other representatives of the other party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments, personnel, information technology systems, and records, and both IBTX and SouthState shall cooperate with the other party in preparing to execute after the Effective Time the conversion or consolidation of systems and business operations generally, and, during such period, IBTX and SouthState shall, and shall cause its Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement or proxy statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws (other than reports or documents that IBTX is not permitted to disclose in accordance with Section 9.14 or otherwise under applicable law), and (ii) all other information concerning its business, properties and personnel as such party may reasonably request. Neither SouthState nor IBTX nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of SouthState’s or IBTX’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary

58

​

​

duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.
(b)Each of SouthState and IBTX shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or Representatives pursuant to Section 6.3(a) in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated January 2, 2024 by and between SouthState and IBTX (as it may be amended in accordance with its terms, the “Confidentiality Agreement”).
(c)No investigation by either of the parties or their respective Representatives shall affect or be deemed to modify or waive the representations and warranties of the other set forth in this Agreement.
6.4 Shareholders’ Approvals.
(a)Each of SouthState and IBTX shall call a meeting of its shareholders (the “SouthState Meeting” and the “IBTX Meeting”, respectively, and such meetings together, the “Meetings”) to be held as soon as reasonably practicable after the S-4 is declared effective (but in no event later than 40 days after the S-4 is declared effective), for the purpose of obtaining (a) in the case of SouthState, the Requisite SouthState Vote, and, in the case of IBTX, the Requisite IBTX Vote and (b) if so desired and agreed by SouthState and IBTX, a vote upon other matters of the type customarily brought before a meeting of shareholders in connection with the approval of a merger agreement or the transactions contemplated thereby. Each of SouthState and IBTX shall use its reasonable best efforts to cause such Meetings to occur on the same date. Subject to Section 6.4(b), each of SouthState and IBTX and its respective Board of Directors shall use its reasonable best efforts to obtain from the shareholders of SouthState and IBTX, as applicable, the Requisite SouthState Vote and the Requisite IBTX Vote, as applicable, including by communicating to the respective shareholders of SouthState and IBTX its respective recommendation (and including such recommendation in the Joint Proxy Statement) that, in the case of SouthState, the shareholders of SouthState approve this Agreement and the transactions contemplated hereby (the “SouthState Board Recommendation”), and, in the case of IBTX, the shareholders of IBTX approve this Agreement and the transactions contemplated hereby (the “IBTX Board Recommendation”). Each of SouthState and IBTX and their respective Boards of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the SouthState Board Recommendation, in the case of SouthState, or the IBTX Board Recommendation, in the case of IBTX, (ii) fail to make the SouthState Board Recommendation, in the case of SouthState, or the IBTX Board Recommendation, in the case of IBTX, in the Joint Proxy Statement, (iii) adopt, approve, recommend or endorse an Acquisition Proposal, or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the SouthState Board Recommendation, in the case of SouthState, or the IBTX Board Recommendation, in the case of IBTX, in each case within 10 Business Days (or such fewer number of days as remains prior to the applicable Meeting) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing actions described in clauses (i) through (v), a “Recommendation Change”) or (vi) execute or enter into any letter of intent, memorandum of understanding, agreement in principle, merger agreement,

59

​

​

acquisition agreement or other similar agreement (other than an Acceptable Confidentiality Agreement) providing for an Acquisition Proposal (an “Alternative Acquisition Agreement”).
(b)Notwithstanding anything in this Agreement to the contrary, subject to Section 8.1 and Section 8.2, prior to the receipt of the Requisite SouthState Vote, in the case of SouthState, and the Requisite IBTX Vote, in the case of IBTX, the Board of Directors of SouthState and the Board of Directors of IBTX, respectively, may effect a Recommendation Change, including submitting this Agreement to its respective shareholders without recommendation (which, for the avoidance of doubt, shall constitute a Recommendation Change by such party), in which event the applicable Board of Directors may communicate the basis for its lack of recommendation to its shareholders in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), if (i)(A) such Board of Directors has received after the date hereof a bona fide Acquisition Proposal which did not result from a breach of Section 6.14, which it believes in good faith, after receiving the advice of its outside counsel and its financial advisor(s), constitutes a Superior Proposal or (B) an Intervening Event has occurred, and (ii) such Board of Directors, after receiving the advice of its outside counsel and its financial advisor(s), determines in good faith that failure to take such actions would be inconsistent with its fiduciary duties under applicable law, in each case, if, but only if, (1) SouthState or IBTX, as applicable, has complied in all material respects with Section 6.14, (2) such party delivers to the other party at least four Business Days’ prior written notice of its intention to take such action, and furnishes to the other party a reasonable description of the events or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the identity of the person making such Acquisition Proposal, a copy of the proposed transaction agreement(s) and all other documents relating to such Acquisition Proposal), (3) prior to taking such action, such party negotiates, and causes its financial, legal, and other advisors to negotiate, in good faith with the other party, during the four Business Day period following such party’s delivery of the notice referred to in such sub-clause (2) above (to the extent the other party desires to so negotiate) any revision to the terms of this Agreement that the other party desires to propose, and (4) after the conclusion of such four Business Day period, the Board of Directors of SouthState or the Board of Directors of IBTX, as applicable, determines in good faith, after giving effect to all of the adjustments or revisions (if any) which may be offered by the other party pursuant to sub-clause (3) above, that, in the case of actions described in clause (i)(A) above, such Acquisition Proposal continues to constitute a Superior Proposal and in case of actions described in either clause (i)(A) or clause (i)(B) above, it nevertheless would be inconsistent with its fiduciary duties under applicable law to make or continue to make the SouthState Board Recommendation or the IBTX Board Recommendation, as applicable (it being agreed that, if such actions are being taken in response to an Acquisition Proposal, in the event that, following delivery of the notice referred to in sub-clause (2) above, there is any material revision to the terms of such Acquisition Proposal, including any revision in price or other improvement in economic terms, the four Business Day period during which the parties agree to negotiate in good faith shall be extended, if applicable, to ensure that at least two Business Days remain to negotiate subsequent to the time IBTX notifies SouthState of any such material revision (it being understood that there may be multiple extensions)). As used in this Agreement, the term “Intervening Event” means, in the case of SouthState or IBTX, any material event, change, effect, development, condition, circumstance or occurrence arising after the date of this Agreement that (I) is not known by, nor reasonably foreseeable to, the applicable Board of

60

​

​

Directors of such party as of the date of this Agreement and (II) does not relate to any Acquisition Proposal in respect of such party; provided, that, for the avoidance of doubt, none of the following shall be considered or taken into account in determining whether an Intervening Event has occurred: (x) changes in the trading price or trading volume of such party’s common stock (it being understood that the underlying cause of such change may be taken into account to the extent not otherwise excluded by this definition) or general developments or changes in the banking industry or in the credit, debt, financial or capital markets or in interest or exchange rates, (y) the fact alone that such party meets or exceeds any internal or published forecasts or projections for any period (it being understood that the underlying cause of such over-performance by such party may be taken into account to the extent not otherwise excluded by this definition) or (z) any event, change, effect, development, condition, circumstance or occurrence resulting from a breach of this Agreement by such party.
(c)Notwithstanding any Recommendation Change, unless this Agreement has been terminated, the IBTX Meeting and the SouthState Meeting shall be convened and this Agreement shall be submitted to the shareholders of IBTX and SouthState at such meetings for the purpose of the shareholders of IBTX or SouthState, as the case may be, considering and voting on approval of this Agreement and any other matters required to be approved by the shareholders of such party in order to consummate the transactions contemplated by this Agreement. Additionally, unless this Agreement has been terminated, neither IBTX nor SouthState shall submit to or for a vote of its shareholders any Acquisition Proposal.
(d)Each of SouthState and IBTX shall adjourn or postpone its Meeting if (i) as of the date of such Meeting there are insufficient shares of SouthState Common Stock or IBTX Common Stock, as applicable, represented (either in person or by proxy) to constitute the quorum necessary to conduct the business of such Meeting, (ii) as of the date of such meeting SouthState or IBTX, as applicable, has not received proxies representing a sufficient number of shares necessary for the approval of this Agreement by its shareholders, or (iii) required by applicable law in order to ensure that any required supplement or amendment to the Joint Proxy Statement required by applicable law is provided to the shareholders of SouthState or IBTX, as applicable, a reasonable amount of time prior to such Meeting; provided that, in the case of clauses (i) and (ii), without the prior written consent of the other party, neither SouthState nor IBTX, as applicable, shall adjourn or postpone its Meeting for more than five Business Days in the case of any individual adjournment or postponement or more than 20 Business Days in the aggregate.
6.5 Legal Conditions to Merger. Subject in all respects to Section 6.1 of this Agreement, each of SouthState and IBTX shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement and the Bank Merger Agreement and (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by IBTX or SouthState or any of their respective Subsidiaries in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement and the Bank Merger Agreement.

61

​

​

6.6 Stock Exchange Listing. SouthState shall cause the shares of SouthState Common Stock to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time.
6.7 Employee Matters.
(a)From the Effective Time through the 12-month anniversary of the Closing Date, subject to Section 6.7(a) of the Company Disclosure Schedule, SouthState shall provide to each employee of IBTX and its Subsidiaries who at the Effective Time becomes an employee of the Surviving Entity or its Subsidiaries (a “Continuing Employee”): (1) base salary or base wage that is no less than the base salary or base wage provided by IBTX and its Subsidiaries to each such Continuing Employee immediately prior to the Effective Time; (2) target annual cash bonus opportunities that are no less favorable than those provided to similarly situated employees of SouthState and its Subsidiaries; (3) target long-term incentive compensation opportunities that are no less favorable than those provided similarly situated employees of SouthState and its Subsidiaries; (4) employee benefits that are in the aggregate no less favorable than those made available to similarly situated employees of SouthState and its Subsidiaries; provided that for purposes of this clause (4), “employee benefits” shall exclude equity and equity-based compensation, long-term incentives, change in control or retention bonuses or benefits, defined benefit pension benefits, retiree medical benefits and severance benefits; and (5) severance benefits for employees not otherwise party to an employment, severance, change in control, or similar contract that provides for severance that are no less favorable than the greater of (x) the severance benefits provided by IBTX and its Subsidiaries as set forth on Section 6.7(a) of the IBTX Disclosure Schedule and (y) the severance benefits generally made available to similarly situated employees of SouthState and its Subsidiaries, subject to such Continuing Employee’s execution, delivery and non-revocation of a general release in favor of IBTX, SouthState and their respective Affiliates (including the Surviving Entity).
(b)For all purposes (including eligibility, participation, vesting and benefit accrual), except not for any purpose under any defined benefit pension plan, retiree medical plan or any frozen plan or to the extent that such credit would result in a duplication of benefits, under the SouthState Benefit Plans, service with or credited by SouthState, IBTX or any of their respective Subsidiaries or predecessors for Continuing Employees shall be treated as service with the Surviving Entity to the same extent that such service was taken into account under the analogous IBTX Benefit Plan prior to the Effective Time. With respect to any SouthState Benefit Plan in which any Continuing Employees first become eligible to participate on or after the Effective Time, SouthState shall use commercially reasonable efforts to (or cause its Subsidiary to): (A) waive all preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous IBTX Benefit Plan in which such employee participated immediately prior to the Effective Time; and (B) provide each such employee and his or her eligible dependents with credit for any co-payments and deductibles paid prior to the Effective Time under a IBTX Benefit Plan (to the same extent that such credit was given under the analogous IBTX Benefit Plan in which such employee participated immediately prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under such SouthState Benefit Plan, in each

62

​

​

case, subject to SouthState receiving all applicable information as reasonably requested by SouthState, including information regarding pre-Closing co-payments and deductibles from IBTX.
(c)If requested by SouthState in writing delivered to IBTX not less than 20 Business Days before the Closing Date, the Board of Directors of IBTX (or the appropriate committee or officers thereof) shall adopt resolutions and take such corporate action as is necessary or appropriate to terminate the IBTX 401(k) Plan (the “IBTX 401(k) Plan”), effective as of the day prior to the Closing Date and contingent upon the occurrence of the Effective Time. If SouthState requests that the IBTX 401(k) Plan be terminated, (i) IBTX shall provide SouthState with evidence that such plan has been terminated (the form and substance of which shall be subject to reasonable review and comment by SouthState) not later than two days immediately preceding the Closing Date, and (ii) the Continuing Employees shall be eligible to participate, effective as of the Effective Time, in a 401(k) plan sponsored or maintained by SouthState, the Surviving Entity or one of their Subsidiaries (the “SouthState 401(k) Plan”), it being agreed that there shall be no gap in participation in a tax-qualified defined contribution plan. SouthState and IBTX shall take any and all actions as may be required, including amendments to the IBTX 401(k) Plan and/or the SouthState 401(k) Plan, to permit the Continuing Employees to make rollover contributions to the SouthState 401(k) Plan of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) in the form of cash, notes (in the case of loans), SouthState Common Stock or a combination thereof in an amount equal to the full account balance distributed to such employee from the IBTX 401(k) Plan.
(d)Nothing in this Agreement shall confer upon any employee, officer, director or consultant of SouthState or IBTX or any of their Subsidiaries or Affiliates any right to continue in the employ or service of the Surviving Entity, IBTX, SouthState or any Subsidiary or Affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Entity, IBTX, SouthState or any Subsidiary or Affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of SouthState or IBTX or any of their Subsidiaries or Affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any IBTX Benefit Plan or SouthState Benefit Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Entity or any of its Subsidiaries or Affiliates to amend, modify or terminate any particular IBTX Benefit Plan or SouthState Benefit Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of Section 9.11, nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including any current or former employee, officer, director or consultant of SouthState or IBTX or any of their Subsidiaries or Affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.
6.8 Indemnification; Directors’ and Officers’ Insurance.
(a)From and after the Effective Time, the Surviving Entity shall indemnify and hold harmless and shall advance expenses as incurred, in each case, to the fullest extent permitted by applicable law, the IBTX Certificate, the IBTX Bylaws and the governing or organizational documents of any IBTX Subsidiary, each present and former director, officer or employee of IBTX and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “IBTX Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees),

63

​

​

judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of, or pertaining to, the fact that such person is or was a director, officer or employee of IBTX or any of its Subsidiaries and pertaining to matters, acts or omissions existing or occurring at or prior to the Effective Time, including matters, acts or omissions occurring in connection with the approval of this Agreement and the transactions contemplated by this Agreement; provided, that in the case of advancement of expenses, any IBTX Indemnified Party to whom expenses are advanced provides an irrevocable undertaking to repay such advances if it is ultimately determined that such IBTX Indemnified Party is not entitled to indemnification. The Surviving Entity shall reasonably cooperate with the IBTX Indemnified Parties, and the IBTX Indemnified Parties shall reasonably cooperate with the Surviving Entity, in the defense of any such claim, action, suit, proceeding or investigation. Without limiting the indemnification and other rights provided in this clause (a), all rights to indemnification and all limitations on liability existing in favor of the IBTX Indemnified Parties as provided in any indemnification agreement in existence on the date of this Agreement and set forth on Section 6.8 of the IBTX Disclosure Schedule shall survive the Merger and shall continue in full force and effect to the fullest extent permitted by law, and shall be honored by the Surviving Entity and its Subsidiaries or their respective successors as if they were the indemnifying party thereunder, without any amendment thereto.
(b)For a period of six years after the Effective Time, the Surviving Entity shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by IBTX (provided, that the Surviving Entity may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the insured) with respect to claims against the present and former officers and directors of IBTX or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time (including the approval of the transactions contemplated by this Agreement); provided, however, that the Surviving Entity shall not be obligated to expend, on an annual basis, an amount in excess of 300% of the current annual premium paid as of the date hereof by IBTX for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Entity shall cause to be maintained policies of insurance which, in the Surviving Entity’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, SouthState or IBTX, in consultation with, but only upon the consent of, SouthState, may (and at the request of SouthState, IBTX shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six-year “tail” policy under IBTX’s existing directors’ and officers’ insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap.
(c)The obligations of the Surviving Entity, SouthState or IBTX under this Section 6.8 shall not be terminated or modified after the Effective Time in a manner so as to adversely affect any IBTX Indemnified Party or any other person entitled to the benefit of this Section 6.8 without the prior written consent of the affected IBTX Indemnified Party or affected person.

64

​

​

(d)The provisions of this Section 6.8 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each IBTX Indemnified Party and his or her heirs and representatives. If the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity of such consolidation or merger, or (ii) transfers all or substantially all of its assets or deposits to any other person or engages in any similar transaction, then in each such case, the Surviving Entity will cause proper provision to be made so that the successors and assigns of the Surviving Entity will expressly assume the obligations set forth in this Section 6.8.
6.9 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of SouthState, on the one hand, and a Subsidiary of IBTX, on the other hand) or to vest the Surviving Entity with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger or the Bank Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by the Surviving Entity.
6.10 Advice of Changes. SouthState and IBTX shall each promptly advise the other party of any effect, change, event, circumstance, condition, occurrence or development (i) that has had or would reasonably be expected to, either individually or in the aggregate, have a Material Adverse Effect on such first party, or (ii) that such first party believes would or would reasonably be expected to cause or constitute a material breach of any of its representations, warranties, obligations, covenants or agreements contained in this Agreement that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.10 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case, unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 6.10 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice.
6.11 Dividends. After the date of this Agreement, each of SouthState and IBTX shall coordinate with the other the declaration of any dividends in respect of SouthState Common Stock and IBTX Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that the holders of IBTX Common Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of IBTX Common Stock and any shares of SouthState Common Stock any such holder receives in exchange therefor in the Merger.
6.12 Shareholder Litigation. Each party shall give the other party prompt notice of any shareholder litigation against such party or its directors or officers relating to the transactions contemplated by this Agreement. IBTX shall (i) give SouthState the opportunity to participate (at SouthState’s expense) in the defense or settlement of any such litigation, (ii) give SouthState a reasonable opportunity to review and comment on all filings or responses to be made by IBTX in connection with any such litigation, and will in good faith take such comments into

65

​

​

account and (iii) not agree to settle any such litigation without SouthState’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that the other party shall not be obligated to consent to any settlement which does not include a full release of such other party and its Affiliates or which imposes an injunction or other equitable relief after the Effective Time upon the Surviving Entity or any of its Affiliates.
6.13 Board Representation. Prior to the Effective Time, the Board of Directors of SouthState shall take all actions necessary so that three directors of IBTX immediately prior to the Effective Time shall be appointed to the Board of Directors of SouthState as of the Effective Time (such appointed directors, the “IBTX Designated Directors”). The IBTX Designated Directors (i) shall be directors of IBTX immediately prior to the Effective Time and (ii) shall be selected by mutual agreement of SouthState and IBTX (provided that, for the avoidance of doubt, (i) the Chief Executive Officer of IBTX as of the date hereof shall be one of the IBTX Designated Directors and (ii) the Lead Independent Director of the Board of Directors of IBTX as of the date hereof shall be one of the IBTX Designated Directors).
6.14 Acquisition Proposals.
(a)Each party will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than the parties hereto with respect to any Acquisition Proposal. Each party agrees that it will not, and will cause each of its Subsidiaries not to, and will use its reasonable best efforts to cause its and their respective officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any Acquisition Proposal (except to notify a person that has made or, to the knowledge of such party, is making any inquiries with respect to, or is considering making, an Acquisition Proposal, of the existence of the provisions of this Section 6.14(a)), or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement (whether written or oral, binding or nonbinding) (other than an Acceptable Confidentiality Agreement entered into in accordance with this Section 6.14) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite SouthState Vote, in the case of SouthState, or the Requisite IBTX Vote, in the case of IBTX, a party receives an unsolicited bona fide written Acquisition Proposal that did not result from or arise in connection with a breach of this Section 6.14(a) by such party, such party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Board of Directors of such party concludes in good faith (after receiving the advice of outside counsel and financial advisor(s)) that failure to take such actions would be inconsistent with its fiduciary duties under applicable law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, such party shall have provided such information to the other party and shall have entered

66

​

​

into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to such party than the Confidentiality Agreement (“Acceptable Confidentiality Agreement”), which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. Each party will promptly (within 24 hours) advise the other party following receipt of any Acquisition Proposal or any inquiry which would reasonably be expected to lead to an Acquisition Proposal and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the other party with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or Acquisition Proposal, and will keep the other party apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Each party shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof. As used in this Agreement, “Acquisition Proposal” shall mean, with respect to a party, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of such party and its Subsidiaries or 25% or more of any class of equity or voting securities of such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning 25% or more of any class of equity or voting securities of such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party. As used in this Agreement, “Superior Proposal” shall mean, with respect to a party, any bona fide written Acquisition Proposal which the Board of Directors of such party determines, in good faith, after taking into account all legal, financial, regulatory, and other aspects of such proposal (including the amount, form, and timing of payment of consideration, the financing thereof, any associated break-up or termination fees, including those provided for in this Agreement, expense reimbursement provisions, and all conditions to consummation) and the person making the proposal, and after consulting with its financial advisor (which shall be a nationally recognized investment banking firm) and outside legal counsel, is (i) more favorable from a financial point of view to such party’s shareholders than the transactions contemplated by this Agreement (taking into account any proposal by the other party to amend the terms of this Agreement pursuant to Section 6.4(b)) and (ii) if accepted, reasonably likely to be timely consummated on the terms set forth; provided, however, that for purposes of this definition of Superior Proposal, references to “25%” in the definition of Acquisition Proposal shall be deemed to be references to “50%.” It is agreed that any violation of the restrictions on a party set forth in this Section 6.14(a) by any officer, director, employee, consultant, advisor or other representative of such party or any of its Subsidiaries, in each case acting on behalf of such party or any of its Subsidiaries, shall be a breach of this Section 6.14(a) by such party.
(b)Nothing contained in this Agreement shall prevent a party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act or Item 1012(a) of Regulation M-A with respect to an Acquisition Proposal or from making any legally

67

​

​

required disclosure to such party’s shareholders; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.
6.15 Public Announcements. IBTX and SouthState agree that the initial press release with respect to the execution and delivery of this Agreement shall be a release mutually agreed to by the parties. Thereafter, each of the parties agrees that no public release or announcement or statement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (i) as required by applicable law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on, such release or announcement in advance of such issuance, (ii) for such releases, announcements or statements that are consistent with other such releases, announcement or statements made after the date of this Agreement in compliance with this Section 6.15, (iii) with respect to any Acquisition Proposal or Superior Proposal (subject to Section 6.4 and Section 6.14) or (iv) for statements that are reasonably necessary in connection with a party enforcing its rights under this Agreement in any litigation between the parties relating to this Agreement. It is understood that SouthState shall assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Mergers and the other transactions contemplated hereby.
6.16 Change of Method. IBTX and SouthState shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the combination of IBTX and SouthState (including the provisions of Article I), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided, that unless this Agreement is amended by agreement of each party in accordance with Section 9.1, no such change shall (i) alter or change the Exchange Ratio or the number of shares of SouthState Common Stock received by holders of IBTX Common Stock in exchange for each share of IBTX Common Stock, (ii) adversely affect the Tax treatment of IBTX’s shareholders or SouthState’s shareholders pursuant to this Agreement, (iii) adversely affect the Tax treatment of IBTX or SouthState pursuant to this Agreement or (iv) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 9.1.
6.17 Takeover Statutes. Neither party nor its Board of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated

68

​

​

by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.
6.18 Treatment of IBTX Indebtedness. At and after the Effective Time, SouthState shall assume the due and punctual performance and observance of the covenants to be performed by IBTX under the indentures set forth on Section 6.18 of the IBTX Disclosure Schedule, and the due and punctual payment of the principal of (and premium, if any) and interest on, the notes governed thereby. In connection therewith, prior to the Effective Time, SouthState and IBTX shall cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, officer’s certificates or other documents, and the parties hereto shall cooperate and use reasonable best efforts to provide any opinion of counsel to the trustee thereof required to make such assumption effective as of the Effective Time.
6.19 Exemption from Liability Under Section 16(b). IBTX and SouthState agree that, in order to most effectively compensate and retain IBTX Insiders, both prior to and after the Effective Time, it is desirable that IBTX Insiders not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable law in connection with the conversion of shares of IBTX Common Stock into shares of SouthState Common Stock in the Merger and the conversion of IBTX Equity Awards into corresponding SouthState Equity Awards in the Merger, and for that compensatory and retentive purposes agree to the provisions of this Section 6.19. IBTX shall deliver to SouthState in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of IBTX subject to the reporting requirements of Section 16(a) of the Exchange Act (the “IBTX Insiders”), and the Board of Directors of SouthState and of IBTX, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, take all such steps as may be required to cause (in the case of IBTX) any dispositions of IBTX Common Stock or IBTX Equity Awards by the IBTX Insiders, and (in the case of SouthState) any acquisitions of SouthState Common Stock or SouthState Equity Awards by any IBTX Insiders who, immediately following the Merger, will be officers or directors of the Surviving Entity subject to the reporting requirements of Section 16(a) of the Exchange Act, in each case, pursuant to the transactions contemplated by this Agreement, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable law.
6.20 Certain Tax Matters. Each of IBTX and SouthState shall use its reasonable best efforts to cause the Merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Each of IBTX and SouthState shall use its reasonable best efforts and shall cooperate with one another to obtain the opinion of counsel referred to in Section 7.2(c) and Section 7.3(c). In connection with the foregoing, (a) IBTX shall deliver to the nationally recognized tax counsel that is delivering the opinion referred to in Section 7.2(c) and Section 7.3(c) a duly executed letter of representations customary for transactions of this type and reasonably satisfactory to either such counsel (the “IBTX Tax Certificate”), and (b) SouthState shall deliver to the nationally recognized tax counsel that is delivering the opinion referred to in Section 7.2(c) and Section 7.3(c) a duly executed letter of representations customary for transactions of this type and reasonably satisfactory to either such counsel (the “SouthState Tax Certificate”), in the case of each of clauses (a) and (b), at such times as either such counsel shall reasonably request.

69

​

​

6.21 IBTX Subsidiary Matters. IBTX shall, and shall cause the IBTX Subsidiaries to, use their respective reasonable best efforts to cause the IBTX Subsidiaries set forth on Section 6.21 of the IBTX Disclosure Schedule to be merged with and into another IBTX Subsidiary, or otherwise dissolved and their affairs wound up, prior to Closing.

(c)by either SouthState or IBTX if the Merger shall not have been consummated on or before the 15-month anniversary of the date of this Agreement (the “Termination Date”), unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein;

is terminated by either SouthState or IBTX pursuant to Section 8.1(c) (Termination Date) without the Requisite SouthState Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.2 were satisfied or were capable of being satisfied prior to such termination), (y) thereafter this Agreement is terminated by IBTX pursuant to Section 8.1(d) (SouthState Breach) as a result of a willful breach or (z) thereafter this Agreement is terminated by SouthState or IBTX pursuant to Section 8.1(g)(ii) (SouthState No Vote) and (B) prior to the date that is 12 months after the date of such termination, SouthState enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then SouthState shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay IBTX, by wire transfer of same-day funds, a fee equal to $186,000,000 (the “SouthState Termination Fee”);

provided, that for purposes of this Section 8.2(b), all references in the definition of Acquisition Proposal to “25%” shall instead refer to “50%.”

(c)(i) In the event that this Agreement is terminated by SouthState pursuant to Section 8.1(e) (IBTX Recommendation Change) or by IBTX or SouthState pursuant to Section 8.1(c) (Termination Date) or Section 8.1(g)(i) (IBTX No Vote), in each case, at a time when this Agreement was terminable by SouthState pursuant to Section 8.1(e) (IBTX Recommendation Change), then IBTX shall pay SouthState, by wire transfer of same-day funds, the IBTX Termination Fee within two Business Days of the date of termination or (ii) in the event that this Agreement is terminated by IBTX pursuant to Section 8.1(f) (SouthState Recommendation Change) or by IBTX or SouthState pursuant to Section 8.1(c) (Termination Date) or Section 8.1(g)(ii) (SouthState No Vote), in each case, at a time when this Agreement was terminable by SouthState pursuant to Section 8.1(f) (SouthState Recommendation Change), then SouthState shall pay IBTX, by wire transfer of same-day funds, the SouthState Termination Fee within two Business Days of the date of termination.
(d)Notwithstanding anything to the contrary in this Agreement, but without limiting the right of any party to recover liabilities or damages arising out of the other party’s Fraud or willful and material breach of any provision of this Agreement, in no event shall either party be required to pay the SouthState Termination Fee or the IBTX Termination Fee, as the case may be, more than once.
(e)Each of SouthState and IBTX acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if a party fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the IBTX Termination Fee or SouthState Termination Fee, as applicable, or any portion thereof, such non-paying party shall pay the costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit. In addition, if a party fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts at a rate per annum equal to the “prime rate” published in the Wall Street Journal on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full.

Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

79

​

​

with Section 8.2 in the event of Fraud or willful and material breach of any provision of this Agreement, it being agreed that in no event shall any IBTX or SouthState shareholder be entitled to enforce any of their rights, or any of the party’s obligations, under this Agreement directly in the event of any such breach, but rather that (i) IBTX shall have the sole and exclusive right to do so in its sole and absolute discretion, as agent for the IBTX shareholders, and (ii) SouthState shall have the sole and exclusive right to do so in its sole and absolute discretion, as agent for the SouthState shareholders, and IBTX or SouthState, as applicable, may retain any amounts obtained in connection therewith.

In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. 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.
9.12 Specific Performance. The parties hereto agree that irreparable damage, for which monetary damages (even if available) would not be an adequate remedy, would occur if any provision of this Agreement were not performed in accordance with the terms hereof and, accordingly, that the parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Merger), in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate, and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.
9.13 Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.
9.14 Confidential Supervisory Information. Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information (including confidential supervisory information as defined in 12 C.F.R. § 261.2(c) and as identified in 12 C.F.R. § 309.5(g)(8)) of a Governmental Entity by any party to this Agreement to the extent prohibited by applicable law.

This Support Agreement (this “Agreement”), dated as of May 17, 2024, is entered into by and among SouthState Corporation, a South Carolina corporation (“SouthState”), and the undersigned shareholders (the “Shareholder”) of Independent Bank Group, Inc., a Texas corporation (“IBTX”).

WHEREAS, subject to the terms and conditions of the Agreement and Plan of Merger (as the same may be amended, supplemented or modified, the “Merger Agreement”), dated as of the date hereof, between SouthState and IBTX, IBTX will be merged with and into SouthState, with SouthState as the surviving corporation (the “Merger”);

WHEREAS, the Board of Directors of IBTX has approved, by the unanimous vote of directors present, the Merger and declared advisable and adopted the Merger Agreement, approved the execution, delivery and performance of the Merger Agreement by IBTX and the consummation of the transactions contemplated thereby, and has resolved to submit the Merger Agreement to its shareholders for approval and to recommend that its shareholders approve the Merger Agreement; and

NOW THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereto agree as follows:

1. | Definitions. Capitalized terms not defined in this Agreement have the meanings assigned to those terms in the Merger Agreement.

2. | Effectiveness; Termination. This Agreement shall be effective upon signing. This Agreement shall automatically terminate and be null and void and of no effect upon (and may only be terminated upon) the earliest to occur of the following: (a) termination of the Merger Agreement for any reason in accordance with its terms, (b) IBTX or the Board of

3. | Support Agreement. From the date hereof until the earlier of (a) the Closing or (b) the termination of the Merger Agreement in accordance with its terms (the “Support Period”), the Shareholder irrevocably and unconditionally hereby agrees that at any meeting (whether annual or special and each postponement, recess, adjournment or continuation thereof) of IBTX’s shareholders, however called, and in connection with any written consent of IBTX’s shareholders, the Shareholder shall (i) appear at such meeting or otherwise cause all of such Shareholder’s Existing Shares and all other shares of Common Stock or voting securities over which such Shareholder has acquired, after the date hereof, beneficial or record ownership and the power to vote or direct the voting thereof (including any shares of Common Stock acquired by means of purchase, dividend or distribution, or issued upon the exercise of any stock options to acquire Common Stock or the conversion of any convertible securities, or pursuant to any other equity awards or derivative securities (including any IBTX Equity Awards) or otherwise) (together with the Existing Shares, the “Shares”), as of the applicable record date, to be counted as present thereat for purposes of calculating a quorum, and (ii) vote or cause to be voted (including by proxy or written consent, if applicable) all such Shares (A) in favor of the approval of the Merger Agreement, the Merger and the other transactions contemplated by the Merger Agreement, (collectively, the “Transactions”), (B) in favor of any proposal to adjourn or postpone such meeting of IBTX’s shareholders to a later date if there are not sufficient votes to approve the Merger Agreement or the Transactions, (C) against any Acquisition Proposal, and (D) against any action, proposal, transaction, agreement or amendment of the IBTX Certificate or IBTX Bylaws, in each case of this clause (D), which would reasonably be expected to (1) result in a breach of any covenant, representation or warranty or any other obligation or agreement of IBTX contained in the Merger Agreement, or of the Shareholder contained in this Agreement, or (2) prevent, impede, delay, interfere with, postpone, discourage or frustrate the purposes of or adversely affect the consummation of the Transactions, including the Merger. The Shareholder agrees to exercise all voting or other determination rights such Shareholder has in any trust or other legal entity to carry out the intent and purposes of such Shareholder’s obligations in this paragraph and otherwise set forth in this Agreement. The Shareholder represents, covenants and agrees that, except for this Agreement, such Shareholder (x) has not entered into, and shall not enter into during the Support Period, any support or voting agreement or voting trust or similar agreement with respect to the Shares that would be inconsistent with such Shareholder’s obligations under this Agreement and (y) has not granted, and shall not grant during the Support Period, a proxy, consent or power of attorney with respect to the Shares except any proxy to carry out the intent of and the Shareholder’s obligations under this Agreement and any revocable proxy granted to officers or directors of IBTX at the request of the Board of Directors of IBTX in connection with election of directors or other routine matters at any annual or special meeting of the IBTX shareholders.

4. | Transfer Restrictions Prior to the Merger. The Shareholder hereby agrees that such Shareholder will not, from the date hereof until the earlier of (a) the end of the Support Period or (b) approval of the Merger Agreement by the shareholders of IBTX by the Requisite IBTX Vote, directly or indirectly, offer for sale, sell, transfer, assign, give, convey, tender in any tender or exchange offer, pledge, encumber, hypothecate or dispose of (by merger, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily, enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of, or enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, conveyance, hypothecation or other transfer or disposition of, any of the Shares, or any legal or beneficial interest therein, whether or not for value and whether voluntary or involuntary or by operation of law (any of the foregoing, a “Transfer”); provided, that the Shareholder may Transfer Shares (i) to any of its Affiliates, (ii) to any other Person to whom SouthState has consented with respect to a Transfer by such Shareholder in advance in writing, and (iii) to (A) any Family Member (as defined below) of such Shareholder or to a trust solely for the benefit of the Shareholder and/or any Family Member of the Shareholder or (B) upon the death of the Shareholder pursuant to the terms of any trust or will of the Shareholder or by the applicable Laws of intestate succession; provided that (x) in the case of clause (i), such Affiliate shall remain an Affiliate of the Shareholder at all times following such Transfer and (y) in the case of clauses (i), (ii) and (iii), so long as the transferee, prior to the date of Transfer, agrees in a signed writing to be bound by and comply with the provisions of this Agreement with respect to such Transferred Shares, and the Shareholder provides at least three Business Days’ prior written notice (which shall include the written consent of the transferee in form reasonably acceptable to SouthState agreeing to be bound by and comply with the provisions of this Agreement) to SouthState, in which case the Shareholder shall remain responsible for any breach of this Agreement by such transferee (any Transfer permitted in accordance with this Section ‎4, a “Permitted Transfer”). In the event of any Transfer that would qualify as a Permitted Transfer under more than one of clauses (i) through (iii), the Transferring Shareholder may elect the clause to which such Transfer is subject for purposes of complying with this Agreement. As used in this Agreement, the term “Family Member” means, with respect to the Shareholder, (I) such Shareholder and such Shareholder’s spouse, individually, (II) any descendant, niece or nephew of such Shareholder or such Shareholder’s spouse, (III) any charitable organization created and primarily funded by any one or more individuals described in the foregoing (I) or (II), (IV) any estate, trust, guardianship, custodianship or other fiduciary arrangement for the primary benefit of any one or more individuals or organizations described in the foregoing (I), (II) or (III), and (V) any corporation, partnership, limited liability company or other business organization controlled by and substantially all of the interests in which are owned, directly or indirectly, by any one or more individuals or organizations named or described in the foregoing (I), (II), (III) or (IV).

The Shareholder agrees that such Shareholder shall not take any action that would make any representation or warranty of such Shareholder contained herein untrue or incorrect or have the effect of preventing, impairing, delaying or adversely affecting the performance by such Shareholder of such Shareholder’s obligations under this Agreement; provided that nothing in this sentence will prohibit any Permitted Transfer. As used in this Agreement, the terms “beneficial owner,” “beneficially own” and “beneficial ownership” shall have the meaning set forth in Rule 13d-3 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Shareholder agrees to notify SouthState as promptly as practicable of any inaccuracies or omissions in any information relating to such Shareholder that is so published or disclosed. The Shareholder shall, if applicable and required, promptly and in accordance with applicable law amend his, her or its Schedule 13D or 13G, as applicable, filed with the Securities and

Nothing in this Agreement, express or implied, is intended to or shall confer upon any person not a party to this Agreement any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. Nothing in this Agreement shall, or shall be construed or deemed to, constitute a Transfer of any Shares or any legal or beneficial interest in or voting or other control over any of the Shares or as creating or forming a “group” for purposes of the Exchange Act, and all rights, ownership and benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, subject to the agreements of the parties set forth herein.

SUPPORT AGREEMENT

This Support Agreement (this “Agreement”), dated as of May 17, 2024, is entered into by and among Independent Bank Group, Inc., a Texas corporation (“IBTX”), and each of the undersigned shareholders (each, a “Shareholder”, and collectively, the “Shareholders”) of SouthState Corporation, a South Carolina corporation (“SouthState”). The obligations of each Shareholder hereunder shall be several and not joint.

WHEREAS, subject to the terms and conditions of the Agreement and Plan of Merger (as the same may be amended, supplemented or modified, the “Merger Agreement”), dated as of the date hereof, between SouthState and IBTX, IBTX will be merged with and into SouthState, with SouthState as the surviving corporation (the “Merger”);

WHEREAS, as of the date of this Agreement, each Shareholder owns beneficially or of record, and has the power to vote or direct the voting of, the shares of common stock, par value $2.50 per share, of SouthState (the “Common Stock”) set forth next to such Shareholder’s name on Schedule A hereto (all such shares, the “Existing Shares”);

WHEREAS, the Board of Directors of SouthState has approved, by the unanimous vote of directors present, the Merger and declared advisable and adopted the Merger Agreement, approved the execution, delivery and performance of the Merger Agreement by SouthState and the consummation of the transactions contemplated thereby, and has resolved to submit the Merger Agreement to its shareholders for approval and to recommend that its shareholders approve the Merger Agreement; and

WHEREAS, each Shareholder is supportive of the Merger Agreement and the transactions contemplated thereby, including the Merger and the SouthState Share Issuance, and has determined that it is in his, her or its best interests to enter into this Agreement to provide for his, her or its support for the Merger Agreement and such transactions, and this Agreement is further a condition and inducement for IBTX to enter into the Merger Agreement.

NOW THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereto agree as follows:

1. | Definitions. Capitalized terms not defined in this Agreement have the meanings assigned to those terms in the Merger Agreement.

2. | Effectiveness; Termination. This Agreement shall be effective upon signing. This Agreement shall automatically terminate and be null and void and of no effect upon (and may only be terminated upon) the earliest to occur of the following: (a) termination of the Merger Agreement for any reason in accordance with its terms, (b) SouthState or the Board of Directors of SouthState having made a Recommendation Change in accordance with

1

​

​

| Section 6.4 of the Merger Agreement (provided that such Recommendation Change is approved by the Board of Directors of SouthState) or (c) the Effective Time; provided that (i) this Section ‎2 and Sections ‎10 through ‎17 hereof shall survive any such termination and (ii) such termination shall not relieve any party of any liability or damages resulting from any willful or material breach of any of its representations, warranties, covenants or other agreements set forth herein.

3. | Support Agreement. From the date hereof until the earlier of (a) the Closing or (b) the termination of the Merger Agreement in accordance with its terms (the “Support Period”), each Shareholder irrevocably and unconditionally hereby agrees that at any meeting (whether annual or special and each postponement, recess, adjournment or continuation thereof) of SouthState’s shareholders, however called, and in connection with any written consent of SouthState’s shareholders, each Shareholder shall (i) appear at such meeting or otherwise cause all of such Shareholder’s Existing Shares and all other shares of Common Stock or voting securities over which such Shareholder has acquired, after the date hereof, beneficial or record ownership and the power to vote or direct the voting thereof (including any shares of Common Stock acquired by means of purchase, dividend or distribution, or issued upon the exercise of any stock options to acquire Common Stock or the conversion of any convertible securities, or pursuant to any other equity awards or derivative securities (including any SouthState Equity Awards) or otherwise) (together with the Existing Shares, the “Shares”), as of the applicable record date, to be counted as present thereat for purposes of calculating a quorum, and (ii) vote or cause to be voted (including by proxy or written consent, if applicable) all such Shares (A) in favor of the approval of the Merger Agreement, the Merger, the SouthState Share Issuance and the other transactions contemplated by the Merger Agreement (collectively, the “Transactions”), (B) in favor of any proposal to adjourn or postpone such meeting of SouthState’s shareholders to a later date if there are not sufficient votes to approve the Merger Agreement or the Transactions, (C) against any Acquisition Proposal, and (D) against any action, proposal, transaction, agreement or amendment of the SouthState Articles or SouthState Bylaws, in each case of this clause (D), which would reasonably be expected to (1) result in a breach of any covenant, representation or warranty or any other obligation or agreement of SouthState contained in the Merger Agreement, or of a Shareholder contained in this Agreement, or (2) prevent, impede, delay, interfere with, postpone, discourage or frustrate the purposes of or adversely affect the consummation of the Transactions, including the Merger and the SouthState Share Issuance. Each Shareholder agrees to exercise all voting or other determination rights such Shareholder has in any trust or other legal entity to carry out the intent and purposes of such Shareholder’s obligations in this paragraph and otherwise set forth in this Agreement. Each Shareholder represents, covenants and agrees that, except for this Agreement, such Shareholder (x) has not entered into, and shall not enter into during the Support Period, any support or voting agreement or voting trust or similar agreement with respect to the Shares that would be inconsistent with such Shareholder’s obligations under this Agreement and (y) has not granted, and shall not grant during the Support Period, a proxy, consent or power of attorney with respect to the Shares except any proxy to carry out the intent of and the Shareholder’s obligations under this Agreement and any revocable proxy granted to officers or directors of SouthState at the request of the Board of Directors of SouthState in connection with election of directors or other routine matters at any annual or special meeting of the SouthState shareholders. Each Shareholder

​

​

4. | Transfer Restrictions Prior to the Merger. Each Shareholder hereby agrees that such Shareholder will not, from the date hereof until the earlier of (a) the end of the Support Period or (b) approval of the Merger Agreement and the SouthState Share Issuance by the shareholders of SouthState by the Requisite SouthState Vote, directly or indirectly, offer for sale, sell, transfer, assign, give, convey, tender in any tender or exchange offer, pledge, encumber, hypothecate or dispose of (by merger, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily, enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of, or enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, conveyance, hypothecation or other transfer or disposition of, any of the Shares, or any legal or beneficial interest therein, whether or not for value and whether voluntary or involuntary or by operation of law (any of the foregoing, a “Transfer”); provided, that a Shareholder may Transfer Shares (i) to any of its Affiliates, (ii) to any other Person to whom IBTX has consented with respect to a Transfer by such Shareholder in advance in writing, and (iii) to (A) any Family Member (as defined below) of such Shareholder or to a trust solely for the benefit of the Shareholder and/or any Family Member of the Shareholder or (B) upon the death of the Shareholder pursuant to the terms of any trust or will of the Shareholder or by the applicable Laws of intestate succession; provided that (x) in the case of clause (i), such Affiliate shall remain an Affiliate of the Shareholder at all times following such Transfer and (y) in the case of clauses (i), (ii) and (iii), so long as the transferee, prior to the date of Transfer, agrees in a signed writing to be bound by and comply with the provisions of this Agreement with respect to such Transferred Shares, and such Shareholder provides at least three Business Days’ prior written notice (which shall include the written consent of the transferee in form reasonably acceptable to IBTX agreeing to be bound by and comply with the provisions of this Agreement) to IBTX, in which case such Shareholder shall remain responsible for any breach of this Agreement by such transferee (any Transfer permitted in accordance with this Section ‎4, a “Permitted Transfer”).

As used in this Agreement, the terms “beneficial owner,” “beneficially own” and “beneficial ownership” shall have the meaning set forth in Rule 13d-3 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The deposit accounts of the Resulting Bank will be insured by the Federal Deposit Insurance Corporation in accordance with the Federal Deposit Insurance Act.

At the Effective Time, the amount of issued and outstanding capital stock of the Resulting Bank shall be the amount of capital stock of SouthState Bank issued and outstanding immediately prior to the Effective Time.

SECTION 8

Upon the Effective Time, the then outstanding shares of SouthState Bank’s common stock shall continue to remain outstanding shares of SouthState Bank’s common stock, all of which shall be unaffected by the Bank Merger and shall continue to be owned by SouthState.

SECTION 9

Prior to the Effective Time, the Board of Directors of SouthState Bank shall take all actions necessary so that the three directors of Independent appointed to the Board of Directors of SouthState pursuant to the terms of the Holding Company Agreement shall be appointed to the Board of Directors of the Resulting Bank as of the Effective Time, each of whom shall serve until his or her respective successor is duly elected or appointed and qualified or until his or her earlier death, resignation or removal in accordance with the Articles of Association and Bylaws of the Resulting Bank. Effective as of the Effective Time, Dan Strodel shall serve as President of the Texas and Colorado Divisions of the Resulting Bank.

SECTION 10

This Agreement has been approved by Independent, which owns all of the outstanding shares of Independent Bank, and by SouthState, which owns all of the outstanding shares of SouthState Bank.

SECTION 11

It is the intention of the Banks and each of the Banks undertakes and agrees to use its commercially reasonable efforts to cause the Bank Merger to qualify, and to take no action which would cause the Bank Merger not to qualify, for treatment as a “reorganization” within the meaning of Section 368(a) of the Code for federal income tax purposes.

SECTION 12

The Bank Merger is also subject to the following terms and conditions:

(a) The HC Merger shall have closed and become effective.

(b) The OCC shall have approved this Agreement and the Bank Merger and shall have issued all other necessary authorizations and approvals for the Bank Merger, and any statutory waiting period shall have expired.

(c) This Agreement may be amended or terminated, and the Bank Merger may be abandoned, only by the mutual written agreement of Independent Bank and SouthState Bank at any time, whether before or after filings are made for regulatory approval of the Bank Merger and notwithstanding the prior approval of this Agreement and the Bank Merger by the sole shareholder of Independent Bank or SouthState Bank.

SECTION 13

Effective as of the Effective Time, the Articles of Association and Bylaws of the Resulting Bank shall consist of the Articles of Association and Bylaws of SouthState Bank as in effect immediately prior to the Effective Time; provided that the Articles of Association and Bylaws shall be amended effective at or prior to the Effective Time to the extent necessary to give effect to Sections 2 and 9 of this Agreement.

SECTION 14

This Agreement shall automatically terminate if and at the time of any termination of the Holding Company Agreement.

SECTION 15

This Agreement embodies the entire agreement and understanding of the Banks with respect to the transactions contemplated hereby, and supersedes all other prior commitments, arrangements or understandings, both oral and written, among the Banks with respect to the subject matter hereof.

The provisions of this Agreement are intended to be interpreted and construed in a manner so as to make such provisions valid, binding and enforceable. In the event that any provision of this Agreement is determined to be partially or wholly invalid, illegal or unenforceable, then such provision shall be deemed to be modified or restricted to the extent necessary to make such provision valid, binding and enforceable, or, if such provision cannot be modified or restricted in a manner so as to make such provision valid, binding and enforceable, then such provision shall be deemed to be excised from this Agreement and the validity, binding effect and enforceability of the remaining provisions of this Agreement shall not be affected or impaired in any manner.

No waiver, amendment, modification or change of any provision of this Agreement shall be effective unless and until made in writing and signed by the Banks. No waiver, forbearance or failure by any Bank of its rights to enforce any provision of this Agreement shall constitute a waiver or estoppel of such Bank’s right to enforce any other provision of this Agreement or a continuing waiver by such Bank of compliance with any provision hereof.

Except to the extent Federal law is applicable, this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware without regard to principles of conflicts of laws.

This Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Banks’ respective successors and permitted assigns. Unless otherwise expressly stated herein, this Agreement shall not benefit or create any right of action in or on behalf of any person or entity other than the Banks.

This Agreement may be executed in counterparts (including by facsimile or optically-scanned electronic mail attachment), each of which shall be deemed to be original, but all of which together shall constitute one and the same instrument.
