      Agreement, there are 11,201,470 shares of the Company’s common stock issued and outstanding and no shares of the Company’s preferred stock issued and outstanding.  All of the outstanding capital stock of the Company has been duly authorized and
      validly issued and is fully paid and non-assessable.  There are, as of the date hereof, no outstanding options, rights, warrants or other agreements or instruments obligating the Company to issue, deliver or sell, or cause to be issued, delivered or
      sold, additional shares of the capital stock of the Company or obligating the Company to grant, extend or enter into any such option, right, warrant, or other agreement or instrument to or with any Person other than the Company, except the
      Acquisition Agreements and except pursuant to the Company’s equity incentive or employee stock purchase plans duly adopted by the Company’s Board of Directors or assumed by the Company.

    

    

    4.2            No
          Impediment to Transactions.

    

    

    4.2.1            Transaction is Legal and Authorized.  The issuance of the Subordinated Notes pursuant to the Indenture, the borrowing of the aggregate of the Subordinated Note
      Amounts, the execution of the Transaction Documents and compliance by the Company with all of the provisions of the Transaction Documents are within the corporate and other powers of the Company.

    

    

    4.2.2            Agreement,
          Indenture and Registration Rights Agreement.  This Agreement, the Indenture and the Registration Rights Agreement have been duly authorized, executed and delivered by the Company, and, assuming
      due authorization, execution and delivery by the other parties thereto, including the Trustee for purposes of the Indenture, constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their
      terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general equitable principles.

    

    

    4.2.2            Subordinated Notes.  The Subordinated Notes have been duly authorized by the Company and when executed by the Company and completed and authenticated by the Trustee
      in accordance with, and in the forms contemplated by, the Indenture and issued to, delivered to and paid for by the Purchasers in accordance with the terms of this Agreement, will have been duly issued under
      the Indenture and will constitute legal, valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency,
      reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general equitable principles. When executed and delivered, the Subordinated Notes will be substantially in the form attached as an exhibit to
      the Indenture.

    4.2.4            Exemption
          from Registration.  Neither the Company, nor any of its Subsidiaries or Affiliates, nor any Person acting on its or their behalf, has engaged in any form of general solicitation or general
      advertising (within the meaning of Regulation D) in connection with the offer or sale of the Subordinated Notes.  Assuming the accuracy of the representations and warranties of each Purchaser set forth in this Agreement, the Subordinated Notes will
      be issued in a transaction exempt from the registration requirements of the Securities Act. No “bad actor” disqualifying event described in Rule 506(d)(1)(i)-(viii) of the Securities Act (a “Disqualification Event”) is applicable to the
      Company or, to the Company’s knowledge, any Person described in Rule 506(d)(1) (each a “Company Covered Person”). The Company has exercised reasonable care to determine whether any Company Covered Person is subject to a Disqualification Event.
      The Company has complied, to the extent applicable, with its disclosure obligations under Rule 506(e).

    

    

    4.2.5            No
          Defaults or Restrictions.  Neither the execution and delivery of the Transaction Documents by the Company nor compliance by the Company with their respective terms and conditions will (whether
      with or without the giving of notice or lapse of time or both) (i) violate, conflict with or result in a breach of, or constitute a default under:  (1) the Charter or Bylaws; (2) any of the terms, obligations, covenants, conditions or provisions of
      any corporate restriction or of any contract, agreement, indenture, mortgage, deed of trust, pledge, bank loan or credit agreement, or any other agreement or instrument to which Company or the Bank, as applicable, is now a party or by which it or any
      of its properties is now bound; (3) any judgment, order, writ, injunction, decree or demand of any court, arbitrator, grand jury, or Governmental Agency applicable to the Company or the Bank; or (4) any statute, rule or regulation applicable to the
      Company, except, in the case of items (2), (3) and (4), for such violations, conflicts, breaches, and defaults that would not reasonably be expected to have, singularly or in the aggregate, a Material Adverse
      Effect on the Company, or (ii) result in the creation or imposition of any lien, charge or encumbrance of any nature whatsoever upon any property or asset of the Company.  Neither the Company nor the Bank is in default in the performance, observance
      or fulfillment of any of the terms, obligations, covenants, conditions or provisions contained in any indenture or other agreement creating, evidencing or securing Indebtedness or pursuant to which any such Indebtedness is issued, or any other
      agreement or instrument to which the Company or the Bank, as applicable, is a party or by which the Company or the Bank, as applicable, or any of its properties is now bound, except, in each case, only such defaults that would not reasonably be
      expected to have, singularly or in the aggregate, a Material Adverse Effect on the Company.

    

    

    4.2.6            Governmental
          Consent.  No governmental orders, permissions, consents, approvals or authorizations are required to be obtained by the Company that have not been obtained, and no registrations or declarations
      are required to be filed by the Company that have not been filed, in each case in connection with, or in contemplation of, the execution and delivery of, and performance under, the Transaction Documents, except for those pursuant to applicable
      requirements, if any, of the Securities Act, the Exchange Act or state securities laws or “blue sky” laws of the various states and any applicable federal or state banking laws, rules, and regulations.

    

    

    4.3            Possession
          of Licenses and Permits.  The Company and its Subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by
      the appropriate Governmental Agencies necessary to conduct the business now operated by them except where the failure to possess such Governmental Licenses would not, singularly or in the aggregate, have a Material Adverse Effect on the Company; the
      Company and each Subsidiary of the Company is in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, individually or in the aggregate, have a Material Adverse Effect on the
      Company; all of the Governmental Licenses are valid and in full force and effect, except where the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not have a Material Adverse
      Effect on the Company; and neither the Company nor any Subsidiary of the Company has received any written notice of proceedings relating to the revocation or modification of any such Governmental Licenses.

    4.4            Financial
          Condition.

    

    

    4.4.1            Company
          Financial Statements.  The financial statements of the Company included in the Company’s Reports (including the related notes, where applicable), which have been made available to the Purchasers,
      (i) have been prepared from, and are in accordance with, the books and records of the Company; (ii) fairly present in all material respects the results of operations, cash flows, changes in shareholders’ equity and financial position of Company and
      its consolidated Subsidiaries, for the respective fiscal periods or as of the respective dates therein set forth (subject in the case of unaudited statements to recurring year-end audit adjustments normal in nature and amount), as applicable; (iii)
      complied as to form, as of their respective dates of filing, in all material respects with applicable accounting and banking requirements 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.  The books and records of Company have been, and are being, maintained in all material respects in accordance with GAAP and any other applicable legal
      and accounting requirements.  The Company does not have any material liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due) required to be reflected on or reserved against in a balance
      sheet prepared in accordance with GAAP, except for those liabilities that are reflected or reserved against on the consolidated balance sheet of the Company contained in the Company’s Reports for the Company’s most recently completed quarterly or
      annual fiscal period, as applicable, for liabilities associated with the Company’s pending acquisition of Tennessee Community Bank Holdings, Inc. and Community Bank & Trust, for liabilities associated with the Company’s pending acquisition of
      First Advantage Bancorp and First Advantage Bank, and for liabilities incurred in the ordinary course of business consistent with past practice or in connection with this Agreement and the transactions contemplated hereby.

    

    

    4.4.2            Absence
          of Default.  Since the end of the Company’s last fiscal year ended December 31, 2018, no event has occurred which either of itself or with the lapse of time or the giving of notice or both, would
      give any creditor of the Company the right to accelerate the maturity of any material Indebtedness of the Company. The Company is not in default under any Lease, agreement, or instrument, or any law, rule, regulation, order, writ, injunction, decree,
      determination, or award, except for such defaults that, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect on the Company.

    

    

    4.4.3            Solvency.  After giving effect to the consummation of the transactions contemplated by this Agreement, the Company has capital sufficient to carry on its business and transactions and is solvent and able to pay its debts
      as they mature.  No transfer of property is being made and no Indebtedness is being incurred in connection with the transactions contemplated by this Agreement with the intent to hinder, delay or defraud either present or future creditors of the
      Company or any Subsidiary of the Company.

    
      11

      
        


    

    4.4.4            Ownership
          of Property.  The Company and each of its Subsidiaries have good and marketable title to all real property owned by them and good title to all other assets and property owned by them in the
      conduct of their businesses, whether such assets and properties are real or personal, tangible or intangible, including assets and property reflected in the most recent balance sheet contained in the Company’s Reports or acquired subsequent thereto
      (except to the extent that such assets and properties have been disposed of in the ordinary course of business, since the date of such balance sheet), subject to no encumbrances, liens, mortgages, security interests or pledges, except (i) those items
      which secure liabilities for public or statutory obligations or any discount with, borrowing from or other obligations to the Federal Home Loan Bank, inter-bank credit facilities, reverse repurchase agreements or any transaction by the Bank acting in
      a fiduciary capacity, (ii) statutory liens for amounts not yet delinquent or which are being contested in good faith and (iii) such as do not, individually or in the aggregate, materially and adversely affect the value of such property and do not
      materially and adversely interfere with the use made and proposed to be made of such property by the Company or any of its Subsidiaries.  The Company and its Subsidiaries, as lessee, have the right under valid and existing Leases to occupy or use in
      the conduct of their business all real and personal properties presently leased by them that are material to the business of the Company or its Subsidiaries.

    

    

    4.5            No Material Adverse Change.  Since the end of the Company’s last fiscal year ended December 31, 2018, there has been no Material Adverse Effect on the Company.

    

    

    4.6            Legal
          Matters.

    

    

    4.6.1            Compliance
          with Law.  The Company and each of its Subsidiaries (i) has complied with all and (ii) to the Company’s knowledge, is not under investigation with respect to and has not been threatened to be
      charged with or given any notice of any material violation of any applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign government, or any instrumentality or agency thereof, having jurisdiction over the conduct
      of its business or the ownership of its properties, except in each case where it would not reasonably be expected to have a Material Adverse Effect on the Company.  The Company and each of its Subsidiaries is in compliance with, and at all times
      since December 1, 2016, has been in compliance with, (x) all statutes, rules, regulations, orders and restrictions of any domestic or foreign government, or any Governmental Agency, applicable to it, and (y) its own privacy policies and written
      commitments to customers, consumers and employees, concerning data protection, the privacy and security of personal data, and the nonpublic personal information of its customers, consumers and employees, in each case except where the failure to
      comply would not, individually or in the aggregate, result in a Material Adverse Effect on the Company, and at no time during the two years immediately prior to the date hereof has the Company or any of its Subsidiaries received any written notice
      asserting any such noncompliance with any of the foregoing.

    
      12

      
        


    

    4.6.2            Regulatory
          Enforcement Actions.  Neither the Company nor any of the Company’s Subsidiaries nor any of their respective officers or directors is now operating under any material restrictions, written
      agreements, memoranda, commitment letter, supervisory letter or similar regulatory correspondence, or other commitments (other than restrictions of general application) imposed by any Governmental Agency, nor are, to the Company’s knowledge, (a) any
      such restrictions threatened, (b) any agreements, memoranda or commitment letters being sought by any Governmental Agency, or (c) any material legal or regulatory violations previously identified by, or penalties or other remedial action previously
      imposed by, any Governmental Agency unresolved.

    

    

    4.6.3            Pending
          Litigation.  There are no actions, suits, or proceedings pending, or, to the Company’s knowledge, threatened or proposed, against the Company or any of its Subsidiaries at law or in equity or
      before or by any federal, state, municipal, or other governmental department, commission, board, or other administrative agency, domestic or foreign, that, either separately or in the aggregate, would reasonably be expected to have a Material Adverse
      Effect on the Company; and neither the Company nor any of its Subsidiaries is a party to or named as subject to the provisions of any order, writ, injunction, or decree of, or any written agreement with, any court, commission, board or agency,
      domestic or foreign, that either separately or in the aggregate, will have a Material Adverse Effect on the Company.

    

    

    4.6.4            Environmental.    The Company and each of its Subsidiaries are in compliance in all material respects with all Hazardous Materials Laws, except where such noncompliance would not reasonably be expected to have a Material
      Adverse Effect on the Company.  There are no claims or actions pending or, to the Company’s knowledge, threatened against the Company or any of its Subsidiaries by any Governmental Agency or by any other Person relating to any Hazardous Materials or
      pursuant to any Hazardous Materials Law, except for such actions or claims that would not reasonably be expected to have a Material Adverse Effect on the Company.

    

    

    4.6.5            Brokerage
          Commissions.  Except for commissions paid to the Placement Agents, neither the Company nor any Affiliate of the Company is obligated to pay any brokerage commission or finder’s fee to any Person
      in connection with the transactions contemplated by this Agreement.

    

    

    4.6.6                          Investment Company Act.  Neither the Company nor any of its Subsidiaries is an “investment company” or a company “controlled” by an “investment company,” within the meaning of the
      Investment Company Act of 1940, as amended.

    

    

    4.7            No
          Misstatement.  None of the representations, warranties, covenants and agreements made by the Company in this Agreement or in any certificate or other document delivered to the Purchasers by or on
      behalf of the Company pursuant to or in connection with this Agreement contains any untrue statement of a material fact, or omits to state a material fact necessary to make the statements contained therein not misleading in light of the circumstances
      when made and as of the date of this Agreement.

    
      13

      
        


    

    4.8            Internal
          Accounting Controls.  The Company and each of its material Subsidiaries have established and maintain a system of internal control over financial reporting that pertains to the maintenance of records that accurately and fairly reflect
      the transactions of and dispositions of assets by the Company (on a consolidated basis), that provides reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that
      the Company’s and the Bank’s receipts and expenditures and receipts and expenditures of each of the Company’s other material Subsidiaries are being made only in accordance with authorizations of Company management and its Board of Directors, and
      provides reasonable assurance regarding prevention or timely detection of the unauthorized acquisition, use or disposition of assets of the Company on a consolidated basis that could have a Material Adverse Effect on the Company.  The Company
      believes such system of internal control over financial reporting is effective to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of the Company’s financial statements for external
      purposes in accordance with GAAP.  Since the conclusion of the Company’s last completed fiscal year there has not been and there currently is not, to the Company’s knowledge, (i) any significant deficiency or material weakness in the design or
      operation of its internal control over financial reporting which is reasonably likely to adversely affect its ability to record, process, summarize and report financial information, or (ii) any fraud, whether or not material, that involves management
      or other employees who have a significant role in the Company’s or the Bank’s internal control over financial reporting.  The Company (A) has implemented and maintains disclosure controls and procedures it believes are reasonably designed and
      maintained to ensure that material information relating to the Company is made known to the Chief Executive Officer and the Chief Financial Officer of the Company by others within the Company and (B) has disclosed, based on its most recent evaluation
      prior to the date hereof, to the Company’s outside auditors and the audit committee of the Company’s Board of Directors any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting
      which are reasonably likely to adversely affect the Company’s internal controls over financial reporting and of which the Company has knowledge.  Such disclosure controls and procedures are effective for the purposes for which they were established.

    

    

    4.9            Tax
          Matters.  The Company and each of its Subsidiaries have (i) filed all material foreign, U.S. federal, state and local tax returns, information returns and similar reports that were required to be filed by them prior to the date hereof,
      or requests for extensions to file such returns have been timely filed, and all such tax returns were true, correct and complete in all material respects, and (ii) paid all material taxes required to be paid by them other than taxes (x) currently
      payable without penalty or interest, or (y) being contested in good faith by appropriate proceedings.

    

    

    4.10            Representations
          and Warranties Generally.  The representations and warranties of the Company set forth in this Agreement, or in any other agreement entered into by the Company pursuant to the requirements of this Agreement, are true and correct as of the date hereof and as otherwise specifically provided herein or therein.

    

    

    5.            GENERAL
          COVENANTS, CONDITIONS AND AGREEMENTS.

    

    

    The Company hereby further covenants and agrees with each Purchaser as follows:

    

    

    5.1            Compliance
          with Transaction Documents.  The Company shall comply with, observe and timely perform each and every one of the covenants, agreements and obligations of the Company under the Transaction
      Documents.

    
      14

      
        


    

    5.2            Affiliate
          Transactions.  The Company shall not itself, nor shall it cause, permit or allow any of its Subsidiaries to, enter into any transaction, including the purchase, sale or exchange of property or
      the rendering of any service, with any Affiliate of the Company except in the ordinary course of business and pursuant to the reasonable requirements of the Company’s or such Affiliate’s business and upon terms consistent with applicable laws and
      regulations and reasonably found by the appropriate Board(s) of Directors to be fair and reasonable and no less favorable to the Company or such Affiliate than would be obtained in a comparable arm’s length transaction with a Person not an Affiliate.

    

    

    5.3            Compliance with Laws.

    

    

    5.3.1            Generally.  The Company shall comply and cause each of its Subsidiaries to comply in all material respects with all applicable statutes, rules, regulations, orders and restrictions in respect of the conduct of its business
      and the ownership of its properties, except, in each case, where such noncompliance would not reasonably be expected to have a Material Adverse Effect on the Company.

    

    

    5.3.2            Regulated
          Activities.  The Company shall not itself, nor shall it cause, permit or allow any of its Subsidiaries to, (i) engage in any business or activity not permitted by all applicable laws and
      regulations, except where such business or activity would not reasonably be expected to have a Material Adverse Effect on the Company, or (ii) make any loan or advance secured by the capital stock of another bank or depository institution, or acquire
      the capital stock, assets or obligations of or any interest in another bank or depository institution, in each case other than in accordance with applicable laws and regulations.

    

    

    5.3.3            Taxes.  The Company shall and shall cause its Subsidiaries to promptly pay and discharge all taxes, assessments and other governmental charges imposed upon the Company or any of its Subsidiaries or upon the income,
      profits, or property of the Company or any Subsidiary of the Company and all claims for labor, material or supplies which, if unpaid, would by law become a lien or charge upon the property of the Company or any of its Subsidiaries.  Notwithstanding
      the foregoing, none of the Company or any of its Subsidiaries shall be required to pay any such tax, assessment, charge or claim, so long as the validity thereof shall be contested in good faith by appropriate proceedings, and appropriate reserves
      therefor shall be maintained on the books of the Company or such Subsidiary.

     

    

    5.3.4            Corporate
          Existence.  The Company shall do or cause to be done all things reasonably necessary to maintain, preserve and renew its corporate existence and that of the Bank and its and the Bank’s rights and
      franchises; provided, however, that the Company may consummate a merger in which (i) the Company is the surviving entity or (ii) if Company is not the surviving entity, the surviving entity assumes, by
      operation of law or otherwise, all of the obligations of the Company under the Subordinated Notes, and in connection with any such merger, the Bank may be merged with and/or into another bank or depository institution.

    

    

    5.3.5            Tier
          2 Capital.  If all or any portion of the Subordinated Notes ceases to be deemed to be Tier 2 Capital, other than due to the limitation imposed on the capital treatment of subordinated debt during
      the five (5) years immediately preceding the Maturity Date of the Subordinated Notes, the Company will immediately notify the Holder (as defined in the Subordinated Note) of the Subordinated Notes, and thereafter the Company and the Holder will work
      together in good faith to execute and deliver all agreements as reasonably necessary in order to restructure the applicable portions of the obligations evidenced by the Subordinated Notes so that the Subordinated Notes qualify as Tier 2 Capital; provided, however, that nothing contained in this Agreement shall limit the Company’s right to redeem the Subordinated Notes upon the occurrence of a Tier 2 Capital Event
      as described in the Subordinated Notes.

    
      15

      
        


    

    5.4            Absence
          of Control.  It is the intent of the parties to this Agreement that in no event shall the Purchasers, by reason of any of the Transaction Documents, be deemed to control, directly or indirectly,
      the Company, and the Purchasers shall not exercise, or be deemed to exercise, directly or indirectly, a controlling influence over the management or policies of the Company.

    

    

    5.5            Secondary
          Market Transactions. To the extent and so long as not violative of Section 6.4 hereof, each Purchaser shall have the right at any time and from time to time to securitize its Subordinated
      Notes or any portion thereof in a single asset securitization or a pooled loan securitization of rated single or multi-class securities secured by or evidencing ownership interests in the Subordinated Notes (each such securitization is referred to
      herein as a “Secondary Market Transaction”). In connection with any such Secondary Market Transaction, the Company shall, at the Company’s expense, cooperate with the Purchasers and otherwise reasonably assist the Purchasers in satisfying the
      market standards to which the Purchasers customarily adhere or which may be reasonably required in the marketplace or by applicable rating agencies in connection with any such Secondary Market Transaction, but in no event shall the Company be
      required to incur any costs or expenses in excess of $10,000 in connection therewith. Subject to any written confidentiality obligation, information regarding the Company may be furnished, without liability except in the case of gross negligence or
      willful misconduct, by the Purchaser to any Person reasonably deemed necessary by the Purchaser in connection with participation in such Secondary Market Transaction. Each Purchaser shall cause any Person to whom such Purchaser wishes to deliver
      confidential Company information related to a Secondary Market Transaction to execute and deliver to Company a non-disclosure agreement reasonably acceptable to Company unless such Person is a party to a commercially reasonable non-disclosure
      agreement to which Company is a third-party beneficiary. All documents, financial statements, appraisals and other data and information relevant to the Company or the Subordinated Notes may be retained by any such Person, subject to the terms of any
      applicable non-disclosure agreement.

    

    

    5.6            Insurance. At its sole cost and expense, the Company shall maintain, and shall cause each Subsidiary of the Company to maintain, bonds and insurance to such extent and covering such risks as is required by law or as is
      usual and customary for owners of similar businesses and properties in the same general area in which the Company or its Subsidiaries operate. All such bonds and insurance shall be in a form, in an amount, and with insurers recognized as adequate by
      prudent business persons.

    

    

    5.7            Bloomberg;
          DTC Registration.  The Company shall use commercially reasonable efforts to cause the Subordinated Notes to be quoted on Bloomberg and, with respect to Subordinated Notes held by QIBs, shall
      cause such Subordinated Notes to be registered in the name of Cede & Co. as nominee of DTC.

    
      16

      
        


    

    5.8            Rule
          144A Information.  While any Subordinated Notes remain “restricted securities” within the meaning of the Securities Act, the Company will make available, upon request, to any seller of such

    6.            REPRESENTATIONS, WARRANTIES
          AND COVENANTS OF PURCHASERS.

    

    

    Each Purchaser hereby represents and warrants to the Company, and covenants with the Company, severally and not jointly, as follows:

    

    

    6.1            Legal
          Power and Authority.  The Purchaser has all necessary power and authority to execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated
      hereby.  The Purchaser is an entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization.

    

    

    6.2            Authorization
          and Execution.  The execution, delivery and performance of this Agreement and the Registration Rights Agreement have been duly authorized by all necessary action on the part of such Purchaser,
      and, assuming due authorization, execution and delivery by the other parties thereto, this Agreement and the Registration Rights Agreement are each a legal, valid and binding obligation of such Purchaser, enforceable against such Purchaser in
      accordance with its terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general equitable principles.

     

      

    6.3            No
          Conflicts.  Neither the execution or delivery of or performance under the Transaction Documents nor the consummation of any of the transactions contemplated thereby will conflict with, violate,
      or constitute a breach of or a default under (whether with or without the giving of notice or lapse of time or both) (i) the Purchaser’s organizational documents, (ii) any agreement to which the Purchaser is party, (iii) any law applicable to the
      Purchaser or (iv) any order, writ, judgment, injunction, decree, determination or award binding upon or affecting the Purchaser.

    

    

    6.4            Purchase
          for Investment.  The Purchaser is purchasing the Subordinated Notes for its own account and not with a view to distribution and with no present intention of reselling, distributing or otherwise
      disposing of the same.  The Purchaser has no present or contemplated agreement, undertaking, arrangement, obligation, Indebtedness or commitment providing for, or which is likely to compel, a disposition of the Subordinated Notes in any manner.

    

    

    6.5            QIB;
          Institutional Accredited Investor.  The Purchaser is and will be on the Closing Date either (i) a QIB, or (ii) an institutional “accredited investor” as such term is defined in Rule 501(a) of
      Regulation D and as contemplated by subsections (1), (2), (3) and (7) of Rule 501(a) of Regulation D, and has total assets in excess of $5,000,000.

    
      17

      
        


    

    6.6            Financial
          and Business Sophistication.  The Purchaser has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the prospective investment
      in the Subordinated Notes.  The Purchaser has relied solely upon its own knowledge of, and/or the advice of its own legal, financial or other advisors with regard to, the legal, financial, tax and other considerations involved in deciding to invest
      in the Subordinated Notes.

    

    

    6.7            Ability
          to Bear Economic Risk of Investment.  The Purchaser recognizes that an investment in the Subordinated Notes involves substantial risk.  The Purchaser has the ability to bear the economic risk of
      the prospective investment in the Subordinated Notes, including the ability to hold the Subordinated Notes indefinitely, and further including the ability to bear a complete loss of all of the Purchaser’s investment in the Company. The Purchaser has
      adequate means of providing for its current needs and personal contingencies and has no need for liquidity in its investment in the Subordinated Notes.

    

    

    6.8            Information.  The Purchaser acknowledges that:  (i) the Purchaser is not being provided with the disclosures that would be required if the offer and sale of the Subordinated Notes were registered under the Securities Act, nor
      is the Purchaser being provided with any offering circular or prospectus prepared in connection with the offer and sale of the Subordinated Notes; (ii) the Purchaser has conducted its own examination of the Company and the terms of the Subordinated
      Notes to the extent the Purchaser deems necessary to make its decision to invest in the Subordinated Notes; (iii) the Purchaser has availed itself of publicly available financial and other information concerning the Company to the extent the
      Purchaser deems necessary to its decision to purchase the Subordinated Notes; and (iv) the Purchaser has not received nor relied on any form of general solicitation or general advertising (within the meaning of Regulation D) from the Company in
      connection with the offer or sale of the Subordinated Notes.  The Purchaser has reviewed the information set forth in the Company’s Reports, the exhibits and schedules hereto and the information contained in the data room established by the Company
      in connection with the transactions contemplated by this Agreement.

    

    

    6.9            Access
          to Information.  The Purchaser acknowledges that the Purchaser and its advisors have been furnished with all materials relating to the business, finances and operations of the Company that have
      been requested by the Purchaser or its advisors and have been given the opportunity to ask questions of, and to receive answers from, persons acting on behalf of the Company concerning the terms and conditions of the transactions contemplated by this
      Agreement in order to make an informed and voluntary decision to enter into this Agreement.

    

    

    6.10            Investment
          Decision.  The Purchaser has made its own investment decision based upon its own judgment, due diligence and advice from such advisors as it has deemed necessary and not upon any view expressed
      by any other Person, including the Placement Agents (or, with respect to the Indenture, the Trustee).  Neither any inquiries nor any other due diligence investigations conducted by it or its advisors or representatives, if any, shall modify, amend or
      affect its right to rely on the Company’s representations and warranties contained herein.  The Purchaser is not relying upon, and has not relied upon, any advice, statement, representation or warranty made by any Person by or on behalf of the
      Company, including the Placement Agents (or, with respect to the Indenture, the Trustee), except for the express statements, representations and warranties of the Company made or contained in this Agreement.  Furthermore, the Purchaser acknowledges
      that (i) the Placement Agents have not performed any due diligence review on behalf of it and (ii) nothing in this Agreement or any other materials presented by or on behalf of the Company to the Purchaser in connection with the purchase of the
      Subordinated Notes constitutes legal, tax, accounting, or investment advice.

    
      18

      
        


    

    6.11            Private
          Placement; No Registration; Restricted Legends.  The Purchaser understands and acknowledges that the Subordinated Notes are being sold by the Company without registration under the Securities Act
      in reliance on the exemption from federal and state registration set forth in, respectively, Rule 506(b) of Regulation D promulgated under Section 4(a)(2) of the Securities Act and Section 18 of the Securities Act, or any state securities laws, and,
      accordingly, may be resold, pledged or otherwise transferred only if exemptions from the Securities Act and applicable state securities laws are available to it.  The Purchaser is not subscribing for Subordinated Notes as a result of or subsequent to
      any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio, or presented at any seminar or meeting, or any solicitation of a subscription by a Person other
      than representatives of the Company.  The Purchaser further acknowledges and agrees that all certificates or other instruments representing the Subordinated Notes will bear the restrictive legend set forth in the form of Subordinated Note, which is
      attached as an exhibit to the Indenture.  The Purchaser further acknowledges its primary responsibilities under the Securities Act and, accordingly, will not sell or otherwise transfer the Subordinated Notes or any interest therein without complying
      with the requirements of the Securities Act and the rules and regulations promulgated thereunder and the requirements set forth in this Agreement.

    

    

    6.12            Placement
          Agents.  The Purchaser will purchase the Subordinated Note(s) directly from the Company and not from the Placement Agents and understands that neither the Placement Agents nor any other broker or
      dealer have any obligation to make a market in the Subordinated Notes.

    

    

    6.13            Tier
          2 Capital.  If the Company provides notice as contemplated in Section 5.3.5 that all or any portion of the Subordinated Notes ceases to be deemed to be Tier 2 Capital, thereafter the
      Company and the Purchasers will work together in good faith to execute and deliver all agreements as reasonably necessary in order to restructure the applicable portions of the obligations evidenced by the Subordinated Notes so that the Subordinated
      Notes qualify as Tier 2 Capital; provided, however, that nothing contained in this Agreement shall limit the Company’s right to redeem the Subordinated Notes upon the
      occurrence of a Tier 2 Capital Event as described in the Subordinated Notes.

     

      

    6.14            Accuracy
          of Representations.  The Purchaser understands that each of the Placement Agents and the Company will rely upon the truth and accuracy of the foregoing representations, acknowledgements and
      agreements in connection with the transactions contemplated by this Agreement, and agrees that if any of the representations or acknowledgements made by it are no longer accurate as of the Closing Date, or if any of the agreements made by it are
      breached on or prior to the Closing Date, it shall promptly notify the Placement Agents and the Company.

    

    

    6.15            Representations
          and Warranties Generally.  The representations and warranties of Purchaser set forth in this Agreement are true and correct as of the date hereof and will be true and correct as of the Closing
      Date and as otherwise specifically provided herein. None of the representations, warranties, covenants and agreements made by the Purchaser in this Agreement contains any untrue statement of a material fact, or omits to state a material fact
      necessary to make the statements contained therein not misleading in light of the circumstances when made and as of the date of this Agreement. Any certificate signed by a duly authorized representative of Purchaser and delivered to the Company or to
      counsel for the Company shall be deemed to be a representation and warranty by Purchaser to the Company as to the matters set forth therein.

    
      19

      
        


    

    7.            MISCELLANEOUS.

    

    

    7.1            Prohibition
          on Assignment by the Company.  Except as described in Article VII of the Indenture, the Company may not assign, transfer or delegate any of its rights or obligations under this Agreement or the
      Subordinated Notes without the prior written consent of the Purchasers.

          or Amendment.  No waiver or amendment of any term, provision, condition, covenant or agreement herein shall be effective unless in writing and signed by all of the parties hereto. No failure to
      exercise or delay in exercising, by a Purchaser or any Holder of the Subordinated Notes (as defined therein), any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or
      privilege preclude any other or further exercise thereof, or the exercise of any other right or remedy provided by law. The rights and remedies provided in this Agreement are cumulative and not exclusive of any right or remedy provided by law or
      equity.

    

    

    7.4            Severability.  Any provision of this Agreement which is unenforceable or invalid or contrary to law, or the inclusion of which would adversely affect the validity, legality or enforcement of this Agreement, shall be of no
      effect and, in such case, all the remaining terms and provisions of this Agreement shall subsist and be fully effective according to the tenor of this Agreement the same as though any such offending portion had never been included herein. 
      Notwithstanding any of the foregoing to the contrary, if any provisions of this Agreement or the application thereof are held invalid or unenforceable only as to particular persons or situations, the remainder of this Agreement, and the application
      of such provisions to persons or situations other than those to which they shall have been held invalid or unenforceable, shall not be affected thereby, but shall continue valid and enforceable to the fullest extent permitted by law.

    

    

    7.5            Notices.  Any notice which any party hereto may be required or may desire to give hereunder shall be deemed to have been given if in writing and if delivered personally, or if mailed, postage prepaid, by United States

    7.7            No
          Joint Venture.  Nothing contained herein or in any document executed pursuant hereto, and no action or inaction whatsoever on the part of a Purchaser, shall be deemed to make a Purchaser a

      Agreement or the Subordinated Notes.

    

    

    7.10            Choice
          of Law.  This Agreement shall be governed by and construed in accordance with the laws of the State of New York without giving effect to its laws or principles of conflict of laws.  Nothing

      make unlawful any transaction or conduct by a Purchaser which is lawful pursuant to, or which is permitted by, any of the foregoing.

      counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which taken together shall constitute but one and the same instrument.  In the event that
      any signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same
      force and effect as if such facsimile signature page were an original thereof.

     

      

     7.14            Knowledge;
          Discretion.  All references herein to a Purchaser’s or the Company’s knowledge shall be deemed to mean the knowledge of such party based on the actual knowledge of such party’s Chief Executive
      Officer and Chief Financial Officer or such other persons holding equivalent offices.  Unless specified to the contrary herein, all references herein to an exercise of discretion or judgment by a Purchaser, to the making of a determination or
      designation by a Purchaser, to the application of a Purchaser’s discretion or opinion, to the granting or withholding of a Purchaser’s consent or approval, to the consideration of whether a matter or thing is satisfactory or acceptable to a
      Purchaser, or otherwise to or involving the decision making of a Purchaser, shall be deemed to mean that such Purchaser shall decide using the reasonable discretion or judgment of a prudent lender.

    

    

    7.15            Waiver
          of Right to Jury Trial.  TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT THAT THEY MAY HAVE TO A TRIAL BY JURY IN ANY
      LITIGATION ARISING IN ANY WAY IN CONNECTION WITH ANY OF THE TRANSACTION DOCUMENTS, OR ANY OTHER STATEMENTS OR ACTIONS OF THE COMPANY OR THE PURCHASERS.  THE PARTIES HERETO ACKNOWLEDGE THAT THEY HAVE BEEN REPRESENTED IN THE SIGNING OF THIS AGREEMENT

    EXHIBIT C

    

    

    FORM OF OPINION OF COUNSEL

    

    

    1.            Based solely on the Certificates of Existence and other certificates provided to our
      Firm by the Company and the Bank, each of the Company and the Bank is duly incorporated and in existence under the laws of the State of Tennessee.

    

    

    2.            Each of the Company and the Bank has all requisite corporate power and authority to
      carry on its business as currently conducted and to own, lease and operate its current properties and assets.

    

    

    3.            The Company has the corporate power and authority to execute, deliver, and perform
      its obligations under the Transaction Documents to which it is a party and to consummate the transactions contemplated by the Transaction Documents.

    

    

    4.            Each of the Agreement, the Indenture and the Registration Rights Agreement has been
      duly and validly authorized, executed, and delivered by the Company, and each of the Agreement, the Indenture and the Registration Rights Agreement will constitute a valid and binding obligation of the Company, enforceable against the Company in
      accordance with its terms, except that the enforcement thereof may be subject to and limited by (i) bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance, fraudulent transfer or other similar laws now or hereafter in
      effect relating to or affecting creditors’ rights generally and (ii) general principles of equity (whether applied by a court of law or equity) and the discretion of the court before which any proceeding therefor may be brought, and except that
      certain remedies, waivers, and provisions of the Agreement, the Indenture, and the Registration Rights Agreement may not be enforceable, but, subject to the other qualifications set forth in this opinion letter, such unenforceability will not, in our
      opinion, render the Agreement, the Indenture, or the Registration Rights Agreement, as applicable, invalid as a whole or substantially interfere with the practical realization of the principal legal benefits intended to be provided thereby, except to
      the extent of any procedural delay and the economic consequences which may result therefrom.

    

    

    5.            The Subordinated Notes have been duly and validly authorized by the Company and when
      issued by the Company, authenticated by the Trustee and delivered to and paid for by the Purchasers in accordance with the terms of the Agreement and the Subordinated Notes, will have been duly executed, authenticated, issued and delivered and will
      constitute legal, valid and binding obligations of Company, enforceable against Company in accordance with their terms, except that the enforcement thereof may be subject to  and limited by (i) bankruptcy, insolvency, reorganization, receivership,
      moratorium, fraudulent conveyance, fraudulent transfer or other similar laws now or hereafter in effect relating to or affecting creditors’ rights generally and (ii) general principles of equity (whether applied by a court of law or equity) and the
      discretion of the court before which any proceeding therefor may be brought, and except that certain remedies, waivers, and provisions of the Subordinated Notes may not be enforceable, but, subject to the other qualifications set forth in this
      opinion letter, such unenforceability will not, in our opinion, render the Subordinated Notes invalid as a whole or substantially interfere with the practical realization of the principal legal benefits intended to be provided thereby, except to the
      extent of any procedural delay and the economic consequences which may result therefrom.

    6.            The execution and delivery by the Company of the Agreement, the Indenture and the
      Registration Rights Agreement do not, and the performance by it of its obligations thereunder will not, (i) to such counsel’s knowledge, result in a violation by the Company of any applicable provisions of the Tennessee Business Corporation Act or
      (ii) result in a violation of the Company’s Charter or Bylaws, each as currently in effect.

    

    

    7.            Assuming the truth and accuracy of the representations and warranties of each of the
      Purchasers set forth in the Agreement, the Subordinated Notes to be issued and sold by the Company to Purchasers pursuant to the Agreement will be issued in a transaction exempt from the registration requirements of the Securities Act.
