        foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so
        to qualify or to be in good standing would not result in a Material Adverse Effect on the Company and its Subsidiaries, taken as a whole.  The Company is duly registered as a bank holding company under the Bank Holding Company Act of 1956, as
        amended.

    (b) Each of the Company’s Subsidiaries is listed in Exhibit C attached hereto and incorporated herein by this reference.  Each

    (c) The deposit accounts of the Bank are insured by the FDIC up to applicable limits.  The Bank has not received any notice or other
        information indicating that the Bank is not an “insured depository institution” as defined in 12 U.S.C. § 1813, nor has any event occurred which could reasonably be expected to adversely affect the status of the Bank as an FDIC-insured institution.

        event described in Rule 506(d)(1)(i)-(viii) of Regulation D (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”).  To the
        Company’s knowledge, no 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) of Regulation D.

    (e) No Defaults or Restrictions.  Neither the execution and delivery of the Transaction
        Documents nor compliance 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:  (A) the Charter or
        Bylaws of the Company; (B) 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 the Company or Bank, as applicable, is now a party or by which it or any of its properties may be bound or affected; (C) 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 (D) any statute, rule or 

     8

      

    
      
        

    

    regulation applicable to the Company, except, in the case of items (B), (C) or (D), for such violations and conflicts
        that would not reasonably be expected to have, singularly or in the aggregate, a Material Adverse Effect on the Company and its Subsidiaries, taken as a whole, 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 of any kind 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 may be bound or affected, 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 and its Subsidiaries, taken as a whole.

    (f) 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 connection with, or, in contemplation of, the execution
        and delivery of, and performance under, the Transaction Documents, except for 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 and regulations.

    4.4. 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 and its Subsidiaries, taken as whole; 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 and its Subsidiaries, taken as a whole; 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 its
        Subsidiaries, taken as a whole; and neither the Company nor any Subsidiary of the Company has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses.

    4.5. Financial Condition.

    (a) Company Financial Statements.  The financial statements of the Company included in
        the Company’s Reports (including the related notes, where applicable), which have been provided 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 stockholders’ equity and financial position of the 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 as applicable, 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 the 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), except for those liabilities that are reflected or reserved against on the consolidated balance sheet of the Company contained in the 

     9

      

    
      
        

    

    Company’s Reports for the Company’s most recently completed quarterly or annual fiscal period, as applicable, 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.

    (b) 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 other Lease, agreement or instrument, or any law, rule, regulation, order, writ, injunction, decree, determination or award, non-compliance with which could reasonably be expected to result in a Material Adverse Effect
        on the Company.

    (c) 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.

    (d) Ownership of Property.  The Company and each of its Subsidiaries has good and
        marketable title as to all real property owned by it and good title to all assets and properties owned by the Company and such Subsidiary in the conduct of its 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 of Atlanta, 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 affect the value of such property and do not materially interfere with the use made and proposed to be made of such
        property by the Company or any of its Subsidiaries.  The Company and each of its Subsidiaries, as lessee, has the right under valid and existing Leases of real and personal properties that are material to the Company or such Subsidiary, as
        applicable, in the conduct of its business to occupy or use all such properties as presently occupied and used by it.  Such existing Leases and commitments to Lease constitute or will constitute operating Leases for both tax and financial
        accounting purposes except as otherwise disclosed in the Company’s Reports and the Lease expense and minimum rental commitments with respect to such Leases and Lease commitments are as disclosed in all material respects in the Company’s Reports.

    4.6. No Material Adverse Change.  Since the end of the Company’s last fiscal year ended
        December 31, 2018, there has been no development or event which has had or could reasonably be expected to have a Material Adverse Effect on the Company and its Subsidiaries, taken as a whole.

    4.7. Legal Matters.

    (a) Compliance with Law.  The Company and each of its Subsidiaries (i) has complied
        with and (ii) is not under investigation with respect to, and, to the Company’s knowledge, 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 

     10

      

    
      
        

    

    where any such failure to comply or violation would not reasonably be expected to have a Material Adverse Effect on the
        Company and its Subsidiaries, taken as a whole.  The Company and each of its Subsidiaries is in compliance with, and at all times prior to the date hereof 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 any such failure to comply, would not result, individually or in the aggregate, in a Material Adverse Effect on the Company and its
        Subsidiaries, taken as a whole.  At no time during the two years prior to the date hereof has the Company or any of its Subsidiaries received any written notice asserting any violations of any of the foregoing.

    (b) Regulatory Enforcement Actions.  The Company, the Bank and its other Subsidiaries
        are in compliance in all material respects with all laws administered by and regulations of any Governmental Agency applicable to it or to them, the failure to
        comply with which would have a Material Adverse Effect on the Company and its Subsidiaries, taken as a whole.  None of the Company, the Bank, the Company’s or the Bank’s Subsidiaries nor any of their officers or directors is now operating under any
        restrictions, 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, (i) any such restrictions threatened, or (ii) any agreements, memoranda or commitments being sought by any Governmental Agency.

    (c) Pending Litigation.  There are no actions, suits, proceedings or written agreements
        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 its Subsidiaries, taken as a whole, or materially and adversely affect
        issuance or payment of the Subordinated Notes; 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 and its Subsidiaries, taken as a whole.

    (d) Environmental.  No Property is or, to the Company’s knowledge, has been a site for
        the use, generation, manufacture, storage, treatment, release, threatened release, discharge, disposal, transportation or presence of any Hazardous Materials and neither the Company nor any of its Subsidiaries has engaged in such activities.  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.

    (e) Brokerage Commissions.  Except for commissions paid to the Placement Agent, 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.

    (f) 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.

    4.8. Internal Accounting Controls.  The Company, the Bank and each other Subsidiary has
        established and maintains proper and adequate internal accounting controls that provide reasonable assurance that (a) all material transactions are executed with the authorization of the Company’s 

     11

      

    
      
        

    

    management, (b) all material transactions are recorded as necessary to permit preparation of financial statements in
        accordance with GAAP, (c) access to the Company’s material assets is permitted only in accordance with the authorization of the Company’s management.  Such internal accounting controls are 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, to the Company’s knowledge,
        there has not been and there currently is not (x) any material deficiency in the design or operation of its internal accounting controls which is reasonably likely to have a Material Adverse Effect on such system of internal accounting controls, or
        (b) any fraud that involves management or other employees who have a role in the Company’s or the Bank’s internal accounting controls.

    4.9. Tax Matters.  The Company, Bank and each
        Subsidiary of the Company have (a) filed all material foreign, U.S. federal, state and local tax returns, information returns and similar reports that are required to be filed, and all such tax returns are true, correct and complete in all material
        respects, and (b) paid all material taxes required to be paid by it and any other material assessment, fine or penalty levied against it other than taxes
        (x) currently payable without penalty or interest, or (y) being contested in good faith by appropriate proceedings.

    4.10. Exempt Offering.  Assuming the accuracy of
        the Purchasers’ representations and warranties set forth in this Agreement, no registration under the Securities Act is required for the offer and sale of the Subordinated Notes by the Company to the Purchasers.

    4.11. Representations and Warranties Generally.  The representations and warranties of
        the Company set forth in this Agreement or in any other document delivered to the Purchasers by or on behalf of the Company pursuant to or in connection with this Agreement are true and correct in all material respects 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 under the Transaction Documents.

    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.

    (a) Generally.  The Company shall comply and cause the Bank and each of its other
        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 and its Subsidiaries, taken as a whole.

     12

      

    
      
        

    

    (b) Regulated Activities.  The Company shall not itself, nor shall it cause, permit or
        allow the Bank or any other 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 and its Subsidiaries, taken as a whole 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 and safe and sound banking practices.

    (c) Taxes.  The Company shall and shall cause Bank and any other of its Subsidiaries to
        promptly pay and discharge all taxes, assessments and other governmental charges imposed upon the Company, the Bank or any other of its Subsidiaries or upon the income, profits, or property of the Company or any Subsidiary and all claims for labor,
        material or supplies which, if unpaid, might by law become a lien or charge upon the property of the Company, the Bank or any other of its Subsidiaries.  Notwithstanding the foregoing, none of the Company, the Bank or any other 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, the Bank and such other Subsidiary.

    (d) 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 other Subsidiaries and its and their rights and franchises, and comply in all material respects with all related laws applicable to the
        Company, the Bank or the other Subsidiaries.

    (e) Dividends, Payments, and Guarantees During Event of Default.  Upon the occurrence
        of an Event of Default (as defined under the Subordinated Notes), until such Event of Default is cured by the Company or waived by the Noteholders (as defined under the Subordinated Notes) in accordance with Section 18 of the Subordinated Notes,
        and except as required by any federal or state Governmental Agency, the Company shall not (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock;
        (ii) make any payment of principal of, or interest or premium, if any, on, or repay, repurchase or redeem any of the Company’s Indebtedness that ranks equal with or junior to the Subordinated Notes; or (iii) make any payments under any guarantee
        that ranks equal with or junior to the Subordinated Notes, other than (A) any dividends or distributions in shares of, or options, warrants or rights to subscribe for or purchase shares of, any class of the Company’s common stock; (B) any
        declaration of a non-cash dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock under any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto; (C) as a
        result of a reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital stock for another class or series of the Company’s capital stock; (D) the purchase of fractional interests in
        shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; or (E) purchases of any class of the Company’s common stock related to the issuance of
        common stock or rights under any benefit plans for the Company’s directors, officers or employees or any of the Company’s dividend reinvestment plans.

    (f) 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
        Noteholder (as defined in the Subordinated Note), and thereafter the Company and the Noteholder (as defined in the Subordinated Note) 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 to qualify as Tier 2 Capital; provided, however, that 

     13

      

    
      
        

    

    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.

    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 in violation 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 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 more than $10,000 (without
        reimbursement) in costs or expenses in connection with such Secondary Market Transaction.  Subject to any written confidentiality obligation, including the terms of any non-disclosure agreements between the Purchasers and the Company, all
        information regarding the Company may be furnished, without liability except in the case of gross negligence or willful misconduct, to any Purchaser and to any Person reasonably deemed necessary by Purchaser in connection with participation in such
        Secondary Market Transaction.  All documents, financial statements, appraisals and other data relevant to the Company or the Subordinated Notes may be retained by any such Person.

    5.6. 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 Subordinated Notes the information specified in Rule 144A(d)(4) under the Securities Act, unless the Company is then subject to
        Section 13 or 15(d) of the Exchange Act.

    5.7. DTC Registration.  Upon the request of a holder of a Subordinated Note that is a
        QIB and provided that the applicable depository eligibility requirements are met, the Company shall use commercially reasonable efforts to cause the Subordinated Notes held by such QIB to be registered in the name of Cede & Co. as nominee of
        The Depository Trust Company (“DTC”) or a nominee of DTC.

    
      	
              6.

        Purchaser, enforceable against such Purchaser in accordance with its terms, 

     14

      

    
      
        

    

    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, delivery or performance of the Transaction
        Documents nor the consummation of any of the transactions contemplated thereby will conflict with, violate, constitute a breach of or a default (whether with or without the giving of notice or lapse of time or both) under (a) its organizational
        documents, (b) any agreement to which it is party, (c) any law applicable to it or (d) any order, writ, judgment, injunction, decree, determination or award binding upon or affecting it.

    6.4. Purchase for Investment.  It is purchasing the Subordinated Note 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.  It 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. Institutional Accredited Investor.  It is and will be on the Closing Date (a) 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 no less than $5,000,000 in total assets, or (b) a QIB.

        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.  It recognizes that an investment in
        the Subordinated Notes involves substantial risk.  It 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 its investment in the Company.

    6.8. Information.  It acknowledges that:  (a) it is not being provided with the

        as a result, Company has elected to scale its disclosures in the Company’s Reports filed with the SEC and that such Company’s Reports include less extensive disclosure than required of other reporting companies.

    6.9. Access to Information.  It acknowledges that it and its advisors have been
        furnished with all materials relating to the business, finances and operations of the Company that have been requested by it or its advisors and have been given the opportunity to ask questions of, and to receive answers from, 

     15

      

    
      
        

    

    persons acting on behalf of the Company concerning 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.  It 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 or entity, including the Placement Agent.  Neither such 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.  It 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, without limitation, the Placement Agent, except for the express statements, representations and warranties of the Company made or contained in this Agreement. 
        Furthermore, it acknowledges that (a) the Placement Agent has not performed any due diligence review on behalf of it or provided it with any legal, tax or investment advice and (b) nothing in this Agreement or any other materials presented by or on
        behalf of the Company to it in connection with the purchase of the Subordinated Notes constitutes legal, tax or investment advice.

    6.11. Private Placement; No Registration; Restricted Legends.  It understands and
        acknowledges that the Subordinated Notes are characterized as “restricted securities” under the Securities Act and 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 in compliance with the registration requirements of federal and state securities laws or if exemptions from the Securities Act and applicable state
        securities laws are available to it.  It is not subscribing for the 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.  It 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.  It 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. Neither the Placement Agent nor the Company have or has made or are or is making any representation, warranty or covenant, express or implied, as
        to the availability of any exemption from registration under the Securities Act or any applicable state securities laws for the resale, pledge or other transfer of the Subordinated Notes, or that the Subordinated Notes purchased by it will ever be
        able to be lawfully resold, pledged or otherwise transferred.

    6.12. Placement Agent.  It will purchase the Subordinated Note(s) directly from the
        Company and not from the Placement Agent and understands that neither the Placement Agent nor any other broker or dealer has 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(f)
        of the occurrence of the event contemplated in such section, 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 to 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.  It understands that each of the Placement Agent and
        the Company are relying and will rely upon the truth and accuracy of the foregoing representations, acknowledgements and agreements in connection with the transactions contemplated by this Agreement, 

     16

      

    
      
        

    

    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 Agent and the Company.

    6.15. Representations and Warranties Generally.  The representations and warranties of
        the 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.  Any certificate signed by a duly authorized representative of
        the Purchaser and delivered to the Company or to counsel for the Company shall be deemed to be a representation and warranty by the Purchaser to the Company as to the matters set forth therein.

    
      	
              7.

            	
              MISCELLANEOUS.

            

    

    7.1. Prohibition on Assignment by the Company.  Except as described in Section 8(b)
        (Merger or Sale of Assets) of the Subordinated Notes, 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 all the Noteholders (as
        defined in the Subordinated Note).  In addition, in accordance with the terms of the Subordinated Notes, any transfer of such Subordinated Notes by the Noteholders (as defined in the Subordinated Note) must be made in accordance with the Assignment Form attached thereto and the requirements and restrictions thereof.

    7.2. Time of the Essence.  Time is of the essence for this Agreement.

    7.3. Waiver or Amendment.  No waiver or amendment of any term, provision, condition,
        covenant or agreement herein or in the Subordinated Notes shall be effective except with the consent of at least fifty percent (50%) of the aggregate principal amount (excluding any Subordinated Notes held by the Company or any of its Affiliates)
        of the Subordinated Notes at the time outstanding; provided, however, that without the consent of each holder of an affected Subordinated Note, no such amendment or
        waiver may:  (a) reduce the principal amount of the Subordinated Note; (b) reduce the rate of or change the time for payment of interest on any Subordinated Note; (c) extend the maturity of any Subordinated Note, (d) change the currency in which
        payment of the obligations of the Company under this Agreement and the Subordinated Notes are to be made; (e) lower the percentage of aggregate principal amount of outstanding Subordinated Notes required to approve any amendment of this Agreement
        or the Subordinated Notes, (f) make any changes to Section 5 (Events of Default; Acceleration); Section 6 (Failure to Make Payments); Section 7 (Affirmative Covenants of the Company); or Section 8 (Negative Covenants of the Company) of the
        Subordinated Notes that adversely affects the rights of any holder of a Subordinated Note; or (g) disproportionately and adversely affect the rights of any of the holders of the then outstanding Subordinated Notes.  Notwithstanding the foregoing,
        the Company may amend or supplement the Subordinated Notes without the consent of the holders of the Subordinated Notes to cure any ambiguity, defect or inconsistency or to provide for uncertificated Subordinated Notes in addition to or in place of
        certificated Subordinated Notes, or to make any change that does not adversely affect the rights of any holder of any of the Subordinated Notes.  No failure to exercise or delay in exercising, by a Purchaser or any holder of the Subordinated Notes,
        of 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.  No notice or demand on the Company in any case shall, in itself, entitle the Company to any
        other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Purchasers to any other or further action in any circumstances without notice or demand.  No consent or waiver, expressed or implied, by
        the Purchasers to or of any breach or default by the Company in the performance of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of 

     17

      

    
      
        

    

    any other breach or default in the performance of the same or any other obligations of the Company hereunder.  Failure on
        the part of the Purchasers to complain of any acts or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall not constitute a waiver by the Purchasers of their rights hereunder or impair any rights,
        powers or remedies on account of any breach or default by the Company.

    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 invalid 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 provision to persons or situations other than those to which it 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 U.S. registered or certified mail, return
        receipt requested, or if delivered by a responsible overnight commercial courier promising next business day delivery, addressed:

      date of delivery to such courier (provided next business day delivery was requested).

    7.6. Successors and Assigns.  This Agreement shall inure to the
        benefit of the parties and their respective heirs, legal representatives, successors and assigns; except that, (i) unless a Purchaser consents in writing, no assignment made by the Company in violation of this Agreement shall be effective or confer
        any rights on any purported assignee of the Company and (ii) unless such assignment complies with the Assignment Form attached to the Subordinated Notes, no assignment made by a Purchaser shall be effective or confer any rights on any purported
        assignee of Purchaser. The term “successors and assigns” will not include a purchaser of any of the Subordinated Notes from any Purchaser merely because of such purchase 

     18

      

    
      
        

    

    but shall include a purchaser of any of the Subordinated Notes pursuant to an assignment complying with the
        Assignment Form attached to the Subordinated Notes.

    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 partner or joint venturer with the Company.

    7.8. Documentation.  All documents and other matters required by
        any of the provisions of this Agreement to be submitted or furnished to a Purchaser shall be in form and substance satisfactory to such Purchaser.

    7.9. Entire Agreement.  This Agreement and the Subordinated
        Notes, along with any exhibits thereto, constitute the entire agreement between the parties hereto with respect to the subject matter hereof and may not be modified or amended in any manner other than by supplemental written agreement executed by
        the parties hereto.  No party, in entering into this Agreement, has relied upon any representation, warranty, covenant, condition or other term that is not set forth in this Agreement or in 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 herein shall be deemed to limit any rights, powers or privileges which a Purchaser may have pursuant to any law of the United States of America or any rule, regulation or order of any department or agency thereof and nothing herein shall be deemed to make
        unlawful any transaction or conduct by a Purchaser which is lawful pursuant to, or which is permitted by, any of the foregoing.

    7.11. No Third Party Beneficiary.  This Agreement is made for the
        sole benefit of the Company and the Purchasers, and no other Person shall be deemed to have any privity of contract hereunder nor any right to rely hereon to any extent or for any purpose whatsoever, nor shall any other Person have any right of
        action of any kind hereon or be deemed to be a third party beneficiary hereunder; provided, that the Placement Agent may rely on the representations and warranties contained herein to the same extent as if
        it were a party to this Agreement.

    7.12. Legal Tender of United States.  All payments hereunder shall
        be made in coin or currency which at the time of payment is legal tender in the United States of America for public and private debts.

    7.13. Captions; Counterparts.  Captions contained in this
        Agreement in no way define, limit or extend the scope or intent of their respective provisions.  This Agreement may be executed in any number of 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 

     19

      

    
      
        

    

    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 COMPANY AND PURCHASERS 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 COMPANY AND PURCHASERS ACKNOWLEDGE THAT THEY HAVE BEEN REPRESENTED IN THE SIGNING OF THIS AGREEMENT AND IN THE MAKING OF THIS WAIVER BY INDEPENDENT LEGAL COUNSEL SELECTED OF THEIR
        OWN FREE WILL.  THE COMPANY AND PURCHASERS FURTHER ACKNOWLEDGE THAT (I) THEY HAVE READ AND UNDERSTAND THE MEANING AND RAMIFICATIONS OF THIS WAIVER, (II) THIS WAIVER HAS BEEN REVIEWED BY EACH OF THEM AND THEIR COUNSEL AND IS A MATERIAL INDUCEMENT
        FOR ENTRY INTO THIS AGREEMENT AND (III) THIS WAIVER SHALL BE EFFECTIVE AS TO EACH OF SUCH TRANSACTION DOCUMENTS AS IF FULLY INCORPORATED THEREIN.

    7.16. Expenses.  Except as otherwise provided in this Agreement,
        each of the parties will bear and pay all other costs and expenses incurred by it or on its behalf in connection with the transactions contemplated pursuant to this Agreement.

    7.17. Survival.  Each of the representations and warranties set
        forth in this Agreement shall survive the consummation of the transactions contemplated hereby for a period of one year after the date hereof.  Except as otherwise provided herein, all covenants and agreements contained herein shall survive until,
        by their respective terms, they are no longer operative.

        1. Subordinated Notes.  This Subordinated Note is one of an issue of notes of Security Federal Corporation, a South Carolina corporation
            (the “Company”) designated as the “5.25% Fixed-to-Floating Rate Subordinated Notes due November 22, 2034” (the “Subordinated Notes”) issued pursuant to that Subordinated Note Purchase
            Agreement, dated as of the Issue Date (as defined herein), between the Company and the several purchasers of the Subordinated Notes identified on the signature pages thereto (the “Purchase Agreement”).

        2. Payment.  The Company, for value received, promises to pay to [●], or its registered assigns, the principal sum of [●] Dollars (U.S.)
            ($[●]), plus accrued but unpaid interest on November 22, 2034 (“Stated Maturity”) and to pay interest thereon (i) from and including the Issue Date of the Subordinated Notes to but excluding November 22, 2029 or the earlier redemption
            date contemplated by Section 4 of this Subordinated Note, at the rate of 5.25% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months and payable semi-annually in arrears on June 1 and December 1 of each
            year (each, a “Fixed Interest Payment Date”), beginning June 1, 2020, and (ii) from and including November 22, 2029 to but excluding the Stated Maturity or the earlier redemption date contemplated by Section 4 of this
            Subordinated Note, at the rate per annum, reset semi-annually, equal to LIBOR determined on the Interest Determination Date (as defined below) of the applicable interest period plus 357 basis points, computed on the basis of a 360-day year and
            the actual number of days elapsed and payable semi-annually in arrears on June 1 and December 1 of each year (each, a “Floating Interest Payment Date”).

        (a) An “Interest Payment Date” is either a Fixed Interest Payment Date or a Floating Interest Payment Date, as applicable.

        (b) “LIBOR” means the London interbank offered rate for deposits in U.S. dollars having an index maturity of three months in amounts of at
            least $1,000,000, as that rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) at approximately 11:00 a.m., London time, on the second London Banking Day (as defined below) prior to the first day of the
            applicable floating rate interest period (the “Interest Determination Date”).  A “London Banking Day” means any day on which dealings in deposits in U.S. dollars are transacted
              in the London interbank market.

          (i) If no offered rate appears on Reuters screen page “LIBOR01” on the relevant Interest Determination Date at approximately 11:00 a.m., London
            time, then the Company will select four major banks in the London interbank market and will request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least
            $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative of single transactions at that time.  If at least two quotations are provided, LIBOR will be the arithmetic
            average (rounded upward, if necessary, to the nearest .00001 of 1%) of the quotations provided.

          (ii) If fewer than two such quotations contemplated by Section 2(b)(i) above are provided or are available, the Company will select three
            major banks in New York City and will request each of them to provide a quotation of the rate offered by it at approximately 11:00 a.m., New York City time, on the Interest Determination Date for loans in U.S. dollars to leading European banks
            having an index maturity of three months for the applicable interest period in an amount of at least $1,000,000 that is 

         A-3

          

        
          
            

        

        representative of single transactions at that time.  If three quotations are provided, LIBOR will be the arithmetic
            average of the quotations provided.

          (iii) If (A) fewer than the two quotations contemplated by Section 2(b)(i) above, and (B) fewer than the three quotations
            contemplated by Section 2(b)(ii) above are provided or are available, the Company, after consulting such sources as it reasonably deems in good-faith to be comparable to any of the foregoing quotations or display page, or any such
            source as it deems reasonable from which to estimate LIBOR or any of the foregoing lending rates, shall determine LIBOR for the applicable interest period in its sole discretion.

          (iv) Notwithstanding the foregoing clauses (i), (ii) and (iii) of this Section 2:

             (1) If the Company reasonably determines in good faith on the relevant Interest Determination Date that the LIBOR base rate has been
            discontinued, then the Company will use a substitute or successor base rate that it has determined in its sole reasonable discretion is most comparable to the LIBOR base rate, provided that if the Company reasonably determines in good faith
            that there is an industry-accepted substitute or successor base rate, then the Company shall use such substitute or successor base rate (such rate, together with any rate determined by the Company pursuant to Section 2(b)(ii), the “Alternative

              Rate”);

             (2) If the Company has determined to utilize a substitute or successor base rate in accordance with the foregoing, the Company in its
            sole reasonable discretion may determine what business day convention to use, the definition of business day, the Interest Determination Date to be used and any other relevant methodology for calculating such substitute or successor base rate,
            including any adjustment factor needed to make such substitute or successor base rate comparable to the LIBOR base rate, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate; and

             (3) The Company shall provide each Noteholder (as defined herein) with notice of its determination of an Alternative Rate promptly
            after such determination.  If, within five (5) Business Days (as defined herein) after providing such notice, the Company is notified by the Noteholders of at least a majority in principal amount of the outstanding Subordinated Notes that such
            Noteholders reasonably believe that the determination of such Alternative Rate is not consistent with this Section 2, then the Noteholders of at least a majority in principal amount of the outstanding Subordinated Notes, each using
            their commercially reasonable judgment, shall  determine the Alternative Rate.  In the event the Noteholders of a majority in principal amount of the outstanding Subordinated Notes cannot reach agreement on such Alternative Rate within fifteen
            (15) Business Days of the Company’s notification of its proposed Alternative Rate under this Section 2, the Alternative Rate shall be the rate identified by the Noteholder of the largest principal amount of Subordinated Notes, selected
            based on such Noteholder’s commercially reasonable judgment.

        Any payment of principal of or interest on this Subordinated Note that would otherwise become due and payable
          on a day which is not a Business Day shall become due and payable on the next succeeding Business Day, with the same force and effect as if made on the date for payment of such principal or interest, and no interest will accrue in respect of such
          payment for the period after such day.  The term “Business Day” means any day that is not a Saturday or Sunday and that is not a day on which banks in the State of South Carolina are generally authorized or required by law or executive
          order to be closed.

        3. Subordination.

        (a) The indebtedness of the Company evidenced by this Subordinated Note, including the principal and interest on this Subordinated Note, shall be
            subordinate and junior in right of payment to the prior payment in full of all existing claims of creditors of the Company and depositors of Security Federal Bank (the “Bank”) whether now outstanding or subsequently created, assumed, guaranteed
            or incurred (collectively, “Senior Indebtedness”), which shall consist of principal of (and premium, if any) and interest, if any, on:  (i) all indebtedness and obligations of, or guaranteed or assumed by, the Company for money borrowed,
            whether or not evidenced by bonds, debentures, securities, notes or other similar instruments, and including, but not limited to, deposits of the Bank and all obligations to the Company’s general creditors and secured creditors; (ii) any
            deferred obligations of the Company for the payment of the purchase price of property or assets acquired other than in the ordinary course of business; (iii) all obligations, contingent or otherwise, of the Company in respect of any letters of
            credit, bankers’ acceptances, security purchase facilities and similar direct credit substitutes; (iv) any capital lease obligations of the Company; (v) all obligations of the Company in respect of interest rate swap, cap or other agreements,
            interest rate future or option contracts, currency swap agreements, currency future or option contracts, commodity contracts and other similar arrangements or derivative products; (vi) any obligation of the Company to its general creditors, as
            defined for purposes of the capital adequacy regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve”) applicable to the Company, as the same may be amended or modified from time to time; (vii) all
            obligations that are similar to those in clauses (i) through (v) of other persons for the payment of which the Company is responsible or liable as obligor, guarantor or otherwise arising from an off-balance sheet guarantee; (vii) all
            obligations of the types referred to in clauses (i) through (vi) of other persons secured by a lien on any property or asset of the Company, and (viii) in the case of clauses (i) through (viii) above, all amendments, renewals, extensions,
            modifications and refundings of such indebtedness and obligations; except “Senior Indebtedness” does not include (A) the Subordinated Notes, (B) any obligation that by its terms expressly is junior to,
            or ranks equally in right of payment with, the Subordinated Notes, (C) the existing Floating Rate Junior Subordinated Deferrable Interest Debentures due 2036 of the Company (underlying the outstanding trust preferred securities) as of the date
            of the issuance of this Subordinated Note to which this Subordinated Note shall be senior, or (D) any indebtedness between the Company and any of its subsidiaries or Affiliates.  This Subordinated Note is not secured by any assets of the
            Company or any subsidiary or Affiliate of the Company.  The term “Affiliate(s)” means, with respect to any Person (as such term is defined in the Purchase Agreement), such Person’s immediate family members, partners, members or parent
            and subsidiary corporations, and any other Person directly or indirectly controlling, controlled by, or under common control with said Person and their respective Affiliates.

        (b) In the event of any liquidation of the Company, holders of Senior Indebtedness of the Company shall be entitled to be paid in full with such
            interest as may be provided by law before any payment shall be made on account of principal of or interest on this Subordinated Note.  Additionally, in the event of any insolvency, dissolution, assignment for the benefit of creditors or any
            liquidation or winding up of or relating to the Company, whether voluntary or involuntary, holders of Senior Indebtedness shall be entitled to be paid in full before any payment shall be made on account of the principal of or interest on the
            Subordinated Notes, including this Subordinated Note.  In the event of any such proceeding, after payment in full of all sums owing with respect to the Senior Indebtedness, the registered holders of the Subordinated Notes from time to time
            (each, a “Noteholder” and, collectively, the “Noteholders”), together with the holders of any obligations of the Company ranking on a parity with the Subordinated Notes, shall be entitled to be paid from the remaining assets of
            the Company the unpaid principal thereof, and the unpaid interest thereon before any payment or other distribution, whether in cash, property or otherwise, shall be made (i) with respect to any obligation that by its terms expressly is junior
            to in the right of payment to the Subordinated Notes, (ii) with respect to the existing junior subordinated debentures of the Company (underlying the outstanding trust preferred securities) as of the Issue Date to which this Subordinated Note 

         A-5

          

        
          
            

        

        shall be senior, (iii) with respect to any indebtedness between the Company and any of its subsidiaries or Affiliates
            or (iv) on account of any capital stock.

        (c) If there shall have occurred and be continuing (i) a default in any payment with respect to any Senior Indebtedness or (ii) an event of
            default with respect to any Senior Indebtedness as a result of which the maturity thereof is accelerated, unless and until such payment default or event of default shall have been cured or waived or shall have ceased to exist, no payments shall
            be made by the Company with respect to the Subordinated Notes, notwithstanding the provisions of Section 18 hereof.  The provisions of this paragraph shall not apply to any payment with respect to which Section 3(b) above would
            be applicable.

        (d) Nothing herein shall act to prohibit, limit or impede the Company from issuing additional debt of the Company having the same rank as the
            Subordinated Notes or which may be junior or senior in rank to the Subordinated Notes.  Each Noteholder, by its acceptance hereof, agrees to and shall be bound by the provisions of this Section 3.  Each Noteholder, by its acceptance
            hereof, further acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration for each holder of any Senior Indebtedness, whether such Senior Indebtedness was created or
            acquired before or after the issuance of the Subordinated Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such
            subordination provisions in acquiring and continuing to hold or in continuing to hold such Senior Indebtedness.

        4.  Redemption.

        (a) Redemption Prior to Tenth Anniversary.  This Subordinated Note shall not be redeemable by the Company in whole or in part prior to the
            tenth (10th)anniversary of the date upon which this Subordinated Note was originally issued (the “Issue Date”), except in the event of:  (i) a Tier 2 Capital Event (as defined below), (ii) a Tax Event (as defined below) or
            (iii) an Investment Company Event (as defined below).  Upon the occurrence of a Tier 2 Capital Event, a Tax Event or an Investment Company Event, subject to Section 4(f) below, the Company may redeem this Subordinated Note in whole or
            in part at any time, upon giving not less than 10 (ten) calendar days’ notice to the Noteholder of this Subordinated Note at an amount equal to one hundred percent (100%) of the outstanding principal amount being redeemed plus accrued but
            unpaid interest, to but excluding the redemption date.  “Tier 2 Capital Event” means the receipt by the Company of an opinion of counsel to the Company to the effect that there is a material risk that the Subordinated Note no longer
            qualifies as “Tier 2” Capital (as defined by the Federal Reserve) (or its then equivalent) as a result of a change in interpretation or application of law or regulation by any judicial, legislative or regulatory authority that becomes effective
            after the date of Issue Date.  “Tax Event” means the receipt by the Company of an opinion of counsel to the Company that as a result of any amendment to, or change (including any final and adopted (or enacted) prospective change) in, the
            laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws
            or regulations, there is a material risk that interest payable by the Company on the Subordinated Notes is not, or within one hundred and twenty (120) calendar days after the receipt of such opinion will not be, deductible by the Company, in
            whole or in part, for U.S. federal income tax purposes.  “Investment Company Event” means the receipt by the Company of an opinion of counsel to the Company to the effect that there is a material risk that the Company is or, within one
            hundred and twenty (120) calendar days after the receipt of such opinion will be, required to register as an investment company pursuant to the Investment Company Act of 1940, as amended.

        (b) Redemption on or after Tenth Anniversary.  On or after the tenth anniversary of the Issue Date, subject to Section 4(f) below,
            this Subordinated Note shall be redeemable at the option of and by the Company, in whole or in part at any time and from time to time, at an amount equal to one hundred percent 

         A-6

          

        
          
            

        

        (100%) of the outstanding principal amount being redeemed plus accrued but unpaid interest, to but excluding the
            redemption date, but in all cases in a principal amount with integral multiples of $1,000.  In addition, the Company may redeem all or a portion of the Subordinated Notes, at any time upon the occurrence of a Tier 2 Capital Event, Tax Event or
            an Investment Company Event.  The redemption referred to in this Section 4 shall be subject to any required regulatory approvals.

        (c) Partial Redemption.   If less than the then outstanding principal amount of this Subordinated Note is redeemed, (i) a new Subordinated
            Note shall be issued representing the unredeemed portion without charge to the holder thereof and (ii) such redemption shall be effected on a pro rata basis as to the Noteholders.  For purposes of clarity, upon a partial redemption, a like
            percentage of the principal amount of every Subordinated Note held by every Noteholder shall be redeemed.

        (d) No Redemption at Option of Noteholder.  This Subordinated Note is not subject to redemption at the option of the holder of this
            Subordinated Note.

        (e) Effectiveness of Redemption.  If notice of redemption has been duly given and notwithstanding that this Subordinated Note has been
            called for redemption but has not yet been surrendered for cancellation, on and after the date fixed for redemption interest shall cease to accrue on the portion of this Subordinated Note called for redemption, this Subordinated Note shall no
            longer be deemed outstanding with respect to the portion called for redemption and all rights with respect to the portion of this Subordinated Note called for redemption shall forthwith on such date fixed for redemption cease and terminate
            unless the Company shall default in the payment of the redemption price, except only the right of the Noteholder to receive the amount payable on such redemption, without interest.

        (f) Regulatory Approvals.  Any such redemption shall be subject to receipt of any and all required federal and state regulatory approvals
            or non-objections, including, but not limited to, the consent of the Federal Reserve.  In the case of any redemption of this Subordinated Note pursuant to paragraphs (b) or (c) of this Section 4, the Company will give the Noteholder
            notice of redemption, which notice shall indicate the aggregate principal amount of Subordinated Notes to be redeemed, not less than thirty (30) nor more than forty-five (45) calendar days prior to the proposed redemption date.

        (g) Purchase and Resale of the Subordinated Notes.  Subject to any required federal and state regulatory approvals and the provisions of
            this Subordinated Note, the Company shall have the right to purchase any of the Subordinated Notes at any time in the open market, private transactions or otherwise.  If the Company purchases any Subordinated Notes, it may, in its discretion,
            hold, resell or cancel any of the purchased Subordinated Notes.

        5. Events of Default; Acceleration.  Each of the following events shall constitute an “Event of Default”:

        (a) the entry of a decree or order for relief in respect of the Company by
            a court having jurisdiction in the premises in an involuntary case or proceeding under any applicable bankruptcy, insolvency, or reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, and such
            decree or order will have continued unstayed and in effect for a period of sixty (60) consecutive calendar days;

        (b) the commencement by the Company of a voluntary case under any
            applicable bankruptcy, insolvency or reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, or the consent by the Company to the entry of a decree or order for relief in an involuntary case or
            proceeding under any such law;

         A-7

          

        
          
            

        

        (c) the Company (i) becomes insolvent or is unable to pay its debts as
            they mature, (ii) makes an assignment for the benefit of creditors, (iii) admits in writing its inability to pay its debts as they mature, or (iv) ceases to be a bank holding company or financial holding company under the Bank Holding Company
            Act of 1956, as amended;

        (d) the failure of the Company to pay any installment of interest on any
            of the Subordinated Notes as and when the same will become due and payable, and the continuation of such failure for a period of fifteen (15) consecutive calendar days;

        (e) the failure of the Company to pay all or any part of the principal of any of the
            Subordinated Notes as and when the same will become due and payable;

        (f) the liquidation of the Company (for the avoidance of doubt, “liquidation” does not include any merger, consolidation, sale of equity or
            assets or reorganization (exclusive of a reorganization in bankruptcy) of the Company or any of its subsidiaries); or

        (g) the default or breach of the Company to materially perform any other covenant or agreement on the part of the Company contained in the
            Subordinated Notes and the continuation of such default or breach (without such default or breach having been waived in accordance with the provisions of Section 17) for a period of 90 consecutive calendar days after there has been
            given to the Company by the Holders of not less than 25.0% in principal amount of the outstanding Subordinated Notes, by registered or certified mail, in the manner set forth in Section 22, a written notice specifying such default or breach and
            requiring it to be remedied, and stating that such notice is a “Notice of Default” hereunder.

        Unless the principal of this Subordinated Note already shall have become due and payable, if an Event of Default
            described in Section 5(a) or Section 5(b) shall have occurred and be continuing, the holder of this Subordinated Note, by notice in writing
            to Company, may declare the principal amount of this Subordinated Note to be due and payable immediately and, upon any such declaration, the same shall become and shall be immediately due and payable.  The Company waives demand, presentment for
            payment, notice of nonpayment, notice of protest, and all other notices.  Notwithstanding the foregoing, because the Company will treat the Subordinated Notes as Tier 2 Capital, upon the occurrence of an Event of Default other than an Event of
            Default described in Section 5(a) or Section 5(b), the Noteholders may not accelerate the Stated Maturity of the Subordinated Notes and make
            the principal of, and any accrued and unpaid interest on, the Subordinated Notes, immediately due and payable.  The Company, within forty-five (45) calendar days after the receipt of written notice from any Noteholder of the occurrence of an Event of Default with respect to this
            Subordinated Note, shall mail to all Noteholders, at their addresses shown on the Security Register (as defined in Section 14 below), such written notice of Event of Default, unless such Event of Default shall have been cured or waived before the giving of such notice as certified by the Company in
            writing.

        Prior to any acceleration of this Subordinated Note, a Noteholder may waive pursuant to Section 18 below any past Event of Default. In addition, a Noteholder may rescind a
          declaration of acceleration of this Subordinated Note before any judgment has been obtained if (i) the Company pays all matured installments of principal of and interest on this Subordinated Note (other than installments due by reason of
          acceleration) and interest on the overdue installments; and (ii) all other Events of Default with respect to this Subordinated Note have been cured or waived.

        6. Failure to Make Payments.  In the event of any failure by the Company to make any required payment of principal or interest on this
            Subordinated Note (and in the case of payment of interest, such failure to pay shall have continued for thirty (30) calendar days), the Company will, upon demand of the Noteholder of this Subordinated Note, pay to the Noteholder of this
            Subordinated Note the amount then due and payable on this Subordinated Note for principal and interest (without acceleration of the Note in 

         A-8

          

        
          
            

        

        any manner), with interest on the overdue principal and interest at the rate borne by this Subordinated Note, to the
            extent permitted by applicable law.  If the Company fails to pay such amount upon such demand, the Noteholder of this Subordinated Note may, among other things, institute a judicial proceeding for the collection of the sums so due and unpaid,
            may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the amounts adjudged or decreed to be payable in the manner provided by law out of the property of the Company.

        Upon the occurrence of a failure by the Company to make any required payment of principal or interest on this Subordinated Note, or an Event of Default
          until such Event of Default is cured by the Company or waived by the Noteholders in accordance with Section 18 hereof, the Company shall not, except as required by any federal or state governmental agency:  (a) declare or pay any distributions
          on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company’s capital stock; (b) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any indebtedness of the
          Company that ranks equal with or junior to the Subordinated Notes; or (c) make any payments under any guarantee that ranks equal with or junior to the Subordinated Notes, other than (i) any dividends or distributions in shares of, or options,
          warrants or rights to subscribe for or purchase shares of, any class of the Company’s common stock; (ii) any declaration of a non-cash dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock under
          any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto; (iii) as a result of a reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital
          stock for another class or series of the Company’s capital stock; (iv) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being
          converted or exchanged; or (v) purchases of any class of the Company’s common stock related to the issuance of common stock or rights under any benefit plans for the Company’s directors, officers or employees or any of the Company’s dividend
          reinvestment plans.

        7. Affirmative Covenants of the Company.

        (a) Notice of Certain Events.  To the extent permitted by applicable statute, rule or regulation, the Company shall provide written notice
            to the Noteholder of the occurrence of any of the following events as soon as practicable, but in no event later than fifteen (15) Business Days following the Company becoming aware of the occurrence of such event:

          (i) the total risk-based capital ratio, Tier 1 risk-based capital ratio, common equity Tier 1 risk-based capital ratio or leverage ratio of the
            Company (but only to the extent the Company is required to measure and report such ratios on a consolidated basis under applicable law) or any of the Company’s banking subsidiaries becomes less than ten percent (10.0%), eight percent (8.0%),
            six and one-half percent (6.50%) or five percent (5.0%), respectively;

          (ii) the Company, or any officer of the Company, becomes subject to any formal, written regulatory enforcement action (as defined by the
            applicable state or federal regulatory authority);

          (iii) the appointment, resignation, removal or termination of the Chief Executive Officer, President, Chief Administrative Officer,

        (b) Payment of Principal and Interest.  The Company covenants and
            agrees for the benefit of the Noteholder of this Subordinated Note that it will duly and punctually pay the principal of, and interest on, this Subordinated Note, in accordance with the terms hereof.

        (c) Maintenance of Office.  The Company will maintain an office or
            agency in the city of Aiken, South Carolina where Subordinated Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Subordinated Notes may be served.  The
            Company may also from time to time designate one or more other offices or agencies where the Subordinated Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no
            such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the city of Aiken, South Carolina.  The Company will give prompt written notice to the Noteholders of any such
            designation or rescission and of any change in the location of any such other office or agency.

        (d) Corporate Existence.  The Company will do or cause to be done
            all things necessary to preserve and keep in full force and effect:  (i) the corporate existence of the Company; (ii) the existence (corporate or other) of each subsidiary; and (iii) the rights (charter and statutory), licenses and franchises
            of the Company and each of its subsidiaries; provided, however, that the Company will not be required to preserve the existence (corporate or other) of any of
            its subsidiaries or any such right, license or franchise of the Company or any of its subsidiaries if the Board of Directors of the Company determines that the preservation thereof is no longer desirable in the conduct of the business of the
            Company and its subsidiaries taken as a whole and that the loss thereof will not be disadvantageous in any material respect to the Noteholders.

        (e) Maintenance of Properties.  The Company will, and will cause
            each of its subsidiaries to, cause all its properties used or useful in the conduct of its business to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all
            necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all
            times; provided, however, that nothing in this Section 7 will prevent the Company or any subsidiary from discontinuing the operation and maintenance of
            any of their respective properties if such discontinuance is, in the judgment of the Board of Directors of the Company or of any subsidiary, as the case may be, desirable in the conduct of its business.

        (f) Compliance Certificate.  The Company will deliver to the
            Noteholders, within 120 calendar days after the end of each fiscal year, an Officer’s Certificate covering the preceding calendar year, stating whether or not, to the best of his or her knowledge, the Company is in default in the performance
            and observance of any of the terms, provisions and conditions of this Subordinated Note (without regard to notice requirements or periods of grace) and if the Company will be in default, specifying all such defaults and the nature and status
            thereof of which he or she may have knowledge.

        (g) Tier 2 Capital.  Whether or not the
            Company is subject to consolidated capital requirements under applicable regulations of the Federal Reserve, if all or any portion of the Subordinated Notes ceases to qualify as 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 Stated Maturity of the Subordinated Notes, the Company will promptly notify the Noteholder and thereafter, subject to the Company’s right to redeem the
            Subordinated Notes under such circumstances pursuant to the terms of the Subordinated Notes, if requested by the Company, the Company and the Noteholder 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 to qualify as Tier 2 Capital; provided, however,
            that nothing contained in this Section 7(g) shall limit the Company’s right to redeem the Subordinated Notes upon the occurrence of a Tier 2 Capital Event pursuant to Section 4(a) or Section 4(b).

        (h) Compliance with Laws.  The Company shall comply with the requirements of all laws, regulations, orders and decrees applicable to it or
            its properties, except for such noncompliance that would not reasonably be expected to have a Material Adverse Effect (as such term is defined in the Purchase Agreement) on the Company and its subsidiaries, taken as a whole.

        (i) Taxes and Assessments.  The Company shall punctually pay and discharge all material taxes, assessments, and other governmental charges
            or levies imposed upon it or upon its income or upon any of its properties; provided, that no such taxes, assessments or other governmental charges need be paid if they are being contested in good faith by the Company.

        (j) Financial Statements; Access to Records.

          (i) Not later than forty-five (45) calendar days following the end of each fiscal quarter for which the Company has not submitted a Consolidated
            Financial Statements for Holding Companies Reporting Form FR Y-9C to the Federal Reserve, upon request, the Company shall provide the Noteholder with a copy of the Company’s unaudited parent company only balance sheet and statement of income
            (loss) for and as of the end of such immediately preceding fiscal quarter, prepared in accordance with past practice.  Quarterly financial statements, if required herein, shall be unaudited and need not comply with generally accepted accounting
            principles (“GAAP”).

          (ii) Not later than one hundred and twenty (120) calendar days from the end of each fiscal year, upon request the Company shall provide the
            Noteholder with copies of the Company’s audited financial statements consisting of the consolidated balance sheet of the Company as of the fiscal year end and the related statements of income (loss) and retained earnings, stockholders’ equity
            and cash flows for the fiscal year then ended.  Such financial statements shall be prepared in accordance with GAAP applied on a consistent basis throughout the period involved.

        8.  Negative Covenants of the Company.

        (a) Limitation on Dividends.  The Company shall not declare or pay any dividend or make any distribution on capital stock or other equity
            securities of any kind of the Company if the Company is not “well capitalized” for regulatory capital purposes under Section 225.2(r) of Regulation Y immediately prior to the declaration of such dividend or distribution, except for dividends
            payable solely in shares of common stock of the Company.

        (b) Merger or Sale of Assets.  The Company shall not merge into another entity, or convey, transfer or lease substantially all of its
            properties and assets to any person, unless:

          (i) the continuing entity into which the Company is merged or the person which acquires by conveyance or transfer or which leases substantially
            all of the properties and assets of the Company shall be a corporation, association or other legal entity organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and expressly assumes
            the due and punctual payment of the principal of and any premium and interest on the Subordinated Notes according to their terms, and the due and punctual performance of all covenants and conditions hereof on the part of the Company to be
            performed or observed; and

          (ii) immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would
            become an Event of Default, shall have happened and be continuing.

        9. Global Subordinated Notes.

        (a) Provided that applicable depository eligibility requirements are met, upon the written election of any Noteholder that is a Qualified
            Institutional Buyer, as defined in Rule 144A under the Securities Act, the Company shall use its commercially reasonable efforts to provide that the Subordinated Notes owned by Noteholders that are Qualified Institutional Buyers shall be issued
            in the form of one or more Global Subordinated Notes (each, a “Global Subordinated Note”) registered in the name of The Depository Trust Company or another organization registered as a clearing agency under the Securities Exchange Act of
            1934, as amended (the “Exchange Act”), and designated as Depositary by the Company or any successor thereto (the “Depositary”) or a nominee thereof and delivered to such Depositary or a nominee thereof.

        (b) Notwithstanding any other provision herein, no Global Subordinated Note may be exchanged in whole or in part for Subordinated Notes
            registered, and no transfer of a Global Subordinated Note in whole or in part may be registered, in the name of any person other than the Depositary for such Global Subordinated Note or a nominee thereof unless (i) such Depositary advises the
            Company in writing that such Depositary is no longer willing or able to properly discharge its responsibilities as Depositary with respect to such Global Subordinated Note, and no qualified successor is appointed by the Company within 90 days
            of receipt by the Company of such notice, (ii) such Depositary ceases to be a clearing agency registered under the Exchange Act and no successor is appointed by the Company within 90 days after obtaining knowledge of such event, (iii) the
            Company elects to terminate the book-entry system through the Depositary or (iv) an Event of Default shall have occurred and be continuing.  Upon the occurrence of any event specified in clause (i), (ii), (iii) or (iv) above, the Company or its
            agent shall notify the Depositary and instruct the Depositary to notify all owners of beneficial interests in such Global Subordinated Note of the occurrence of such event and of the availability of Subordinated Notes to such owners of
            beneficial interests requesting the same.

        (c) If any Global Subordinated Note is to be exchanged for other Subordinated Notes or canceled in part, or if another Subordinated Note is to be
            exchanged in whole or in part for a beneficial interest in any Global Subordinated Note, then either (i) such Global Subordinated Note shall be so surrendered for exchange or cancellation as provided in this Section 9 or (ii) the
            principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the principal amount of such other Subordinated Note to be so exchanged for a beneficial interest
            therein, as the case may be, by means of an appropriate adjustment made on the records of the Company or, if applicable, the Company’s registrar and transfer agent (“Registrar”), whereupon the Company or, if applicable, the Registrar, in
            accordance with the applicable rules and procedures of the Depositary (“Applicable Depositary Procedures”), shall instruct the Depositary or its authorized representative to make a corresponding adjustment to its records.  Upon any such
            surrender or adjustment of a Global Subordinated Note by the Depositary, accompanied by registration instructions, the Company shall execute and deliver any Subordinated Notes issuable in exchange for such Global Subordinated Note (or any
            portion thereof) in accordance with the instructions of the Depositary.

        (d) Every Subordinated Note executed and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Subordinated Note
            or any portion thereof shall be executed and delivered in the form of, and shall be, a Global Subordinated Note, unless such Subordinated Note is registered in the name of a person other than the Depositary for such Global Subordinated Note or
            a nominee thereof.

        (e) The Depositary or its nominee, as the registered owner of a Global Subordinated Note, shall be the holder of such Global Subordinated Note
            for all purposes under this Subordinated Note, and owners of beneficial interests in a Global Subordinated Note shall hold such interests pursuant to Applicable Depositary Procedures.  Accordingly, any such owner’s beneficial interest in a
            Global Subordinated Note 

         A-12

          

        
          
            

        

        shall be shown only on, and the transfer of such interest shall be effected only through, records maintained by the
            Depositary or its nominee or its Depositary participants.  If applicable, the Registrar shall be entitled to deal with the Depositary for all purposes relating to a Global Subordinated Note (including the payment of principal and interest
            thereon and the giving of instructions or directions by owners of beneficial interests therein and the giving of notices) as the sole holder of the Subordinated Note and shall have no obligations to the owners of beneficial interests therein. 
            The Registrar shall have no liability in respect of any transfers affected by the Depositary.

        (f) The rights of owners of beneficial interests in a Global Subordinated Note shall be exercised only through the Depositary and shall be
            limited to those established by law and agreements between such owners and the Depositary and/or its participants.

        (g) No holder of any beneficial interest in any Global Subordinated Note held on its behalf by a Depositary shall have any rights with respect to
            such Global Subordinated Note, and such Depositary may be treated by the Company and any agent of the Company as the owner of such Global Subordinated Note for all purposes whatsoever.  Neither the Company nor any agent of the Company will have
            any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Subordinated Note or maintaining, supervising or reviewing any records relating to such
            beneficial ownership interests.  Notwithstanding the foregoing, nothing herein shall prevent the Company or any agent of the Company from giving effect to any written certification, proxy or other authorization furnished by a Depositary or
            impair, as between a Depositary and such holders of beneficial interests, the operation of customary practices governing the exercise of the rights of the Depositary (or its nominee) as holder of any Subordinated Note.

        (h) The Company, within thirty (30) calendar days after the receipt of written notice from the Noteholder or any other holder of the Subordinated
            Notes of the occurrence of an Event of Default with respect to this Note, shall mail to all the Noteholders, at their addresses shown on the Security Register, such written notice of Event of Default.

        10. Denominations.  The Subordinated Notes are issuable only in registered form without interest coupons in minimum denominations of
            $1,000 and integral multiples of $1,000 in excess thereof.

        11. Charges and Transfer Taxes.  No service charge will be made for any registration of transfer or exchange of this Subordinated Note, or
            any redemption or repayment of this Subordinated Note, or any conversion or exchange of this Subordinated Note for other types of securities or property, but the Company may require payment of a sum sufficient to pay all taxes, assessments or
            other governmental charges that may be imposed in connection with the transfer or exchange of this Subordinated Note from the Noteholder requesting such transfer or exchange.

        12. Payment Procedures.  Payment of the principal and interest payable on the Stated Maturity will be made by check, by wire transfer or
            by Automated Clearing House (ACH) transfer in immediately available funds to a bank account in the United States designated by the Noteholder of this Subordinated Note if such Noteholder shall have previously provided wire instructions
            to the Company, upon presentation and surrender of this Subordinated Note at the Payment Office (as defined herein) or at such other place or places as the Company shall designate by notice to the Noteholders as the Payment Office, provided that this Subordinated Note is presented to the Company in time for the Company to make such payments in such funds in accordance with its normal procedures.  Payments of interest (other than
            interest payable on the Stated Maturity) shall be made by wire transfer in immediately available funds or check mailed to the registered Noteholder of this Subordinated Note, as such person’s address appears on the Security Register (as defined
            below).  Interest payable on any Interest Payment Date shall be payable to the Noteholder in whose name this Subordinated Note is registered at the close of business on the fifteenth calendar day prior 

         A-13

          

        
          
            

        

        to the applicable Interest Payment Date, without regard to whether such date is a Business Day, except that interest
            not paid on the Interest Payment Date, if any, will be paid to the Noteholder in whose name this Subordinated Note is registered at the close of business on a special record date fixed by the Company (a “Special Record Date”), notice of
            which shall be given to the Noteholder of this Subordinated Note not less than ten (10) calendar days prior to such Special Record Date.  To the extent permitted by applicable law, interest shall accrue, at the rate at which interest accrues on
            the principal of this Subordinated Note, on any amount of principal or interest on this Subordinated Note not paid when due.  All payments on this Subordinated Note shall be applied first against interest due hereunder; and then against
            principal due hereunder.  The Noteholder of this Subordinated Note acknowledges and agrees that the payment of all or any portion of the outstanding principal amount of this Subordinated Note and all interest hereon shall be pari passu in right of payment and in all other respects to the other Subordinated Notes.  In the event that the Noteholder of this Subordinated Note receives payments in excess of its pro rata share of the
            Company’s payments to the Noteholders of all of the Subordinated Notes, then the Noteholder of this Subordinated Note shall hold in trust all such excess payments for the benefit of the Noteholders of the other Subordinated Notes and shall pay
            such amounts held in trust to such other Noteholders upon demand by such Noteholders.

        13. Form of Payment.  Payments of principal and interest on this Subordinated Note shall be made in such coin or currency of the United
            States of America as at the time of payment shall be legal tender for the payment of public and private debts.

        14. Registration of Transfer, Security Register.  Except as otherwise provided herein, this Subordinated Note is transferable in whole or
            in part, and may be exchanged for a like aggregate principal amount of Subordinated Notes of other authorized denominations, by the Noteholder of this Subordinated Note in person, or by its attorney duly authorized in writing, at the Payment
            Office. The Subordinated Notes will initially be issued in certificated form. The Company shall maintain a register providing for the registration of the Subordinated Notes and any exchange or transfer
            thereof (the “Security Register”).  Upon surrender or presentation of this Subordinated Note for exchange or registration of transfer, the Company shall execute and deliver in exchange therefor a Subordinated Note or Subordinated Notes
            of like aggregate principal amount, each in a minimum denomination of $1,000 or any amount in excess thereof which is an integral multiple of $1,000 (and, in the absence of an opinion of counsel satisfactory to the Company to the contrary,
            bearing the restrictive legend(s) set forth hereinabove) and that is or are registered in such name or names requested by the Noteholder.  Any Subordinated Note presented or surrendered for registration of transfer or for exchange shall be duly
            endorsed and accompanied by a written instrument of transfer in such form as is attached hereto and incorporated herein, duly executed by the Noteholder of this Subordinated Note or its attorney duly authorized in writing, with such tax
            identification number or other information for each person in whose name a Subordinated Note is to be issued, and accompanied by evidence of compliance with any restrictive legend(s) appearing on such Subordinated Note or Subordinated Notes as
            the Company may reasonably request to comply with applicable law.  No exchange or registration of transfer of this Subordinated Note shall be made on or after (i) the fifteenth (15th) day immediately preceding the Stated Maturity or
            (ii) the due delivery of notice of redemption.

        15. Priority.  The Subordinated Notes rank pari passu among themselves and pari passu, in the event of any insolvency proceeding, dissolution, assignment for the benefit of creditors, reorganization, restructuring of debt, marshaling of assets and liabilities or similar proceeding
            or any liquidation or winding up of the Company, with all other present or future unsecured subordinated debt obligations of the Company, except any unsecured subordinated debt that, pursuant to its express terms, is senior or subordinate in
            right of payment to the Subordinated Notes and all Senior Indebtedness.

        16. Ownership.  Prior to due presentment of this Subordinated Note for registration of transfer, the Company may treat the Noteholder in
            whose name this Subordinated Note is registered in the Security Register as the absolute owner of this Subordinated Note for receiving payments of principal and interest 

         A-14

          

        
          
            

        

        on this Subordinated Note and for all other purposes whatsoever, whether or not this Subordinated Note be overdue,
            and the Company shall not be affected by any notice to the contrary.

        17. Waiver and Consent.

        (a) Any consent or waiver given by the Noteholder of this Subordinated Note shall be conclusive and binding upon such Noteholder and upon all
            future Noteholders of this Subordinated Note and of any Subordinated Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this
            Subordinated Note.  This Subordinated Note may also be amended or waived pursuant to, and in accordance with, the provisions of Section 7.3 of the Purchase Agreement.  No delay or omission of the holder of this Subordinated Note to exercise any
            right or remedy accruing upon any Event of Default shall impair such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.  Any insured depository institution which shall be a holder of this
            Subordinated Note or which otherwise shall have any beneficial ownership interest in this Subordinated Note shall, by its acceptance of such Subordinated Note (or beneficial interest therein), be deemed to have waived any right of offset with
            respect to the repayment of the indebtedness evidenced thereby.

        (b) No waiver or amendment of any term, provision, condition, covenant or agreement in the Subordinated Notes shall be effective except with the
            consent of the Noteholders holding not less than more than fifty percent (50%) in aggregate principal amount (excluding any Subordinated Notes held by the Company or any of its Affiliates) of the Subordinated Notes at the time outstanding; provided, however, that without the consent of each Noteholder of an affected Subordinated Note, no such amendment or waiver may:  (i) reduce the principal amount of
            any Subordinated Note; (ii) reduce the rate of or change the time for payment of interest on any Subordinated Note; (iii) extend the maturity of any Subordinated Note; (iv) change the currency in which payment of the obligations of the Company
            under the Subordinated Notes are to be made; (v) lower the percentage of aggregate principal amount of outstanding Subordinated Notes required to approve any amendment of the Subordinated Notes; (vi) make any changes to Section 5
            (Events of Default; Acceleration); Section 6 (Failure to Make Payments); Section 7 (Affirmative Covenants of the Company); or Section 8 (Negative Covenants of the Company) of the Subordinated Notes that adversely affects
            the rights of any Noteholder; or (vii) disproportionately affect any of the Noteholders of the then outstanding Subordinated Notes.  Notwithstanding the foregoing, the Company may amend or supplement the Subordinated Notes without the consent
            of the Noteholders to cure any ambiguity, defect or inconsistency or to provide for uncertificated Subordinated Notes in addition to or in place of certificated Subordinated Notes, or to make any change that does not adversely affect the rights
            of any Noteholder of any of the Subordinated Notes.  No failure to exercise or delay in exercising, by any Noteholder of the Subordinated Notes, of 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, except as restricted hereby.  The rights and remedies provided in this
            Subordinated Note are cumulative and not exclusive of any right or remedy provided by law or equity.  No notice or demand on the Company in any case shall, in itself, entitle the Company to any other or further notice or demand in similar or
            other circumstances or constitute a waiver of the rights of the Noteholders to any other or further action in any circumstances without notice or demand.  No consent or waiver, expressed or implied, by the Noteholders to or of any breach or
            default by the Company in the performance of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance of the same or any other obligations of the Company
            hereunder.  Failure on the part of the Noteholders to complain of any acts or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall not constitute a waiver by the Noteholders of their rights
            hereunder or impair any rights, powers or remedies on account of any breach or default by the Company.

        18. Absolute and Unconditional Obligation of the Company.  No provisions of this Subordinated Note shall alter or impair the obligation of
            the Company, which is absolute and unconditional, to pay the principal and interest on this Subordinated Note at the times, places and rate, and in the coin or currency, herein prescribed.

        19. Successors and Assigns.  This Subordinated Note shall be binding upon the Company and inure to the benefit of the Noteholder and its
            respective successors and permitted assigns.  The Noteholder may assign all, or any part of, or any interest in, the Noteholder’s rights and benefits hereunder.  To the extent of any such assignment, such assignee shall have the same rights and
            benefits against the Company and shall agree to be bound by and to comply with the terms and conditions of the Purchase Agreement as it would have had if it were the Noteholder hereunder.

        20. No Sinking Fund; Convertibility.  This Subordinated Note is not entitled to the benefit of any sinking fund.  This Subordinated Note

 ARTICLE II 

GENERAL TERMS AND CONDITIONS OF THE NOTES 

SECTION 2.01.    Designation and Principal Amount. The Notes are hereby authorized and are designated
the 5.875% Senior Notes due 2027, initially limited in aggregate principal amount to $350,000,000. The Notes issued on the date hereof pursuant to the terms of the Indenture shall be in an aggregate principal amount of $350,000,000, which amount
shall be set forth in the Company Order for the authentication and delivery of the Notes pursuant to Section 3.03 of the Base Indenture. In addition, the Company may issue, from time to time in accordance with the provisions of the Indenture,
additional Notes having the same terms and conditions as the Notes issued on the date hereof in all respects (except for the payment of interest accruing prior to the issue date of such additional Notes), so that such additional Notes shall be
consolidated and form a single series with the Notes issued on the date hereof and shall be governed by the terms of the Indenture. 

SECTION 2.02.    Maturity. The principal amount of the Notes shall be due and payable on
December 1, 2027. 
 SECTION 2.03.    Form and Payment. The Notes shall be
issued in substantially the form set forth on Exhibit A hereto and shall have the terms set forth in such form and shall initially be Global Securities for purposes of the Base Indenture. The Notes shall be issued in fully registered book-entry form
without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 
 The Depositary in respect of the Notes
represented by Global Securities shall be The Depository Trust Company. The Global Securities representing the Notes shall be deposited with, or on behalf of, the Depositary and shall be registered in the name of its nominee, Cede & Co.
Except as otherwise set forth in Section 3.05 of the Base Indenture, the Global Securities may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee. 

The Trustee shall act as Paying Agent for the Notes. The Company may choose to pay interest by mailing checks or making wire or other
electronic funds transfers. All money paid by the Company to any Paying Agent that remains unclaimed at the end of two years after the amount is due to Holders shall be repaid to the Company, subject to any applicable abandoned property laws. After
such two-year period, Holders may look only to the Company for payment and not to the Trustee, any other Paying Agent or anyone else. The Company may also arrange for additional payment offices, and may cancel
or change these offices, including any use of the Trustee’s Corporate Trust Office. The Company may appoint and change the Paying Agent without prior notice to the Holders. 

SECTION 2.04.    Interest. Interest on the Notes shall accrue at the rate of 5.875% per annum.
Interest on the Notes shall accrue from November 22, 2019 or the most recent Interest Payment Date to which interest was paid or duly provided for. Interest on the Notes shall be payable in cash semiannually in arrears on June 1 and
December 1, commencing on June 1, 2020 (each an “Interest Payment Date”), to the Holders in whose names the Notes are 

  
 5 

 
registered at the close of business on the May 15 and November 15, as the case may be, immediately preceding such Interest Payment Date (each a “Regular Record Date”).
Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 

SECTION 2.05.    No Sinking Fund. The provisions of Article XII of the Base Indenture shall
not be applicable to the Notes. 
 ARTICLE III 

ADDITIONAL COVENANTS 
 In
addition to the covenants set forth in Article X of the Base Indenture, the Company also covenants and agrees for the benefit of Notes, but not Securities of any other series, as follows: 

SECTION 3.01.    Limitations on Liens. The Company shall not, and will not permit any of its Domestic
Subsidiaries, directly or indirectly, to issue, assume or guarantee any Debt if that Debt is secured by any Lien upon any Principal Property (or portion thereof) of the Company or of any Domestic Subsidiary of the Company or any shares of stock or
Debt of any Domestic Subsidiary, whether owned on June 1, 2009 or thereafter acquired, without effectively securing the Notes equally and ratably with that Debt, so long as such Debt is so secured. The foregoing restriction does not apply to:

 (i)    Liens on any property acquired, constructed or improved by the Company or any Domestic
Subsidiary of the Company after June 1, 2009, which are created or assumed contemporaneously with or within three years after its acquisition, or completion of construction or improvement (or within six months thereafter pursuant to a firm
commitment for financing arrangements entered into within that three-year period) to secure or provide for the payment of the Purchase Price or cost thereof, or Liens existing on any property at the time of its acquisition; 

(ii)    Liens existing on any property, shares of stock or indebtedness acquired from a Person merged with
or into the Company or a Domestic Subsidiary of the Company after June 1, 2009; 
 (iii)    with
respect to any corporation that becomes a Domestic Subsidiary of the Company after June 1, 2009, Liens on property of, or shares of stock or indebtedness issued by, any such corporation existing at the time it becomes a Domestic Subsidiary and
not incurred in connection with or in anticipation of such corporation becoming a Domestic Subsidiary; 

(iv)    Liens to secure Debt of a Domestic Subsidiary owed to the Company or Debt of one of the Domestic
Subsidiaries of the Company owed to another Domestic Subsidiary of the Company; 
 (v)    Liens in favor
of governmental bodies to secure partial, progress, advance or other payments pursuant to any contract or statute; 

  
 6 

 (vi)    any Lien existing on June 1, 2009; or 

(vii)    Liens for the sole purpose of extending, renewing or replacing Debt, in whole or in part, secured
by any Lien referred to in the foregoing clauses (i) to (vi), inclusive; provided, however, that the principal amount of Debt secured by that Lien shall not exceed the principal amount of Debt so secured at the time of such
extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to the property that secured the Lien so extended, renewed or replaced (plus improvements on such property). 

The limitation on Liens described in this Section 3.01 shall not apply to the issuance, assumption or guarantee by the Company or any
Domestic Subsidiary of the Company of Debt secured by a Lien which would otherwise be subject to the foregoing restrictions up to an aggregate amount which, together with all other Debt of the Company and of the Domestic Subsidiaries of the Company
secured by Liens (not including Liens permitted under the foregoing exceptions) and the Attributable Debt with respect to Sale and Leaseback Transactions existing at that time (other than Sale and Leaseback Transactions in which the property
involved would have been permitted to be subject to a Lien under clause (i) above), does not exceed 10% of Consolidated Net Tangible Assets. 

SECTION 3.02.    Limitations on Sale and Leaseback Transactions. The Company and the Domestic
Subsidiaries of the Company are prohibited from entering into Sale and Leaseback Transactions unless: 

(i)    the Company or such Domestic Subsidiary of the Company would be entitled to incur Debt secured by a
Lien on the Principal Property to be leased without equally and ratably securing the Notes, pursuant to clauses (i) - (vii) under Section 3.01 above; or the Attributable Debt with respect thereto would be an amount permitted under the last
paragraph of Section 3.01 above; or 
 (ii)    the Company or such Domestic Subsidiary of the
Company shall, within 180 days of the effective date of any such arrangement, apply an amount equal to the proceeds from such Sale and Leaseback Transaction to the payment or other retirement of Debt that ranks senior to or equal with the Notes
(other than, in either case, Debt owed by the Company or any Subsidiary), or to the purchase of other Principal Property. 
 SECTION
3.03.    Limitations on Guarantees. The Company and the Domestic Subsidiaries of the Company are prohibited from entering into any agreement pursuant to which any such Domestic Subsidiary of the Company
guarantees the payment of Debt incurred by the Company without providing that the Notes be equally and ratably guaranteed by such Domestic Subsidiary of the Company. 

ARTICLE IV

OF THE NOTES 
 SECTION 4.01.    Optional Redemption. On and after December 1, 2022, the
Company may redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ 

  
 7 

 
prior notice to Holders as provided under Section 3.02 and Section 3.03 of the Indenture, at the following redemption prices (expressed as percentages of principal amount of the Notes
to be redeemed), plus accrued and unpaid interest to (but not including) the date the Notes are redeemed (the “Redemption Date”) (subject to the right of Holders of record on the relevant record date to receive interest due on the
Notes on the relevant interest payment date), if redeemed during the 12-month period commencing on or after December 1 of the years set forth below: 

 

					
	Year	  	Redemption
Price	 
	 2022
	  	 	102.938	% 
	 2023
	  	 	101.469	% 
	 2024 and thereafter
	  	 	100.000	% 

 At any time prior to December 1, 2022, the Company may redeem on any one or more occasions up to 35% of
the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional Notes), upon not less than 30 nor more than 60 days’ prior notice to Holders as provided under Section 3.02 and Section 3.03 of
the Indenture, at a redemption price of 105.875% of the principal amount thereof, plus accrued and unpaid interest to (but not including) the Redemption Date, with the net cash proceeds of one or more Equity Offerings; provided,
however, that (1) at least 65.0% of the original aggregate principal amount of Notes (calculated after giving effect to any issuance of additional Notes) remain outstanding immediately after the occurrence of each such redemption and
(2) the redemption occurs within 180 days of the consummation of any such Equity Offering. 
 At any time prior to December 1,
2022, the Company may redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ prior notice to Holders as provided under Section 3.02 and Section 3.03 of the Indenture, at a redemption price equal to 100% of the
principal amount of the Notes to be redeemed, plus the Applicable Premium as of, and accrued and unpaid interest to (but not including), the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest
due on the Notes on the relevant interest payment date). 
 For purposes of determining the optional redemption price, the following
definitions are applicable: 
 “Applicable Premium” means, with respect to the Notes at the Redemption Date, the greater of (i) 1%
of the principal amount of the Notes and (ii) the excess (if any) of (A) the present value at the Redemption Date of (1) the redemption price of such Note on December 1, 2022 (such redemption price being set forth in the first
paragraph in this Section 4.01) plus (2) all required remaining scheduled interest payments due on the Notes through December 1, 2022 (but excluding accrued and unpaid interest to the Redemption Date), computed using a discount rate
equal to the Treasury Rate plus 0.50% over (B) the principal amount of the Notes outstanding on the Redemption Date. The Trustee shall have no obligation to calculate or verify the calculation of the Applicable Premium or of any
component thereof. 
 “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment
Banker as having a maturity comparable to the remaining term (the 

  
 8 

 
“Remaining Life”) of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the Notes (assuming for the purposes of this definition, for the avoidance of doubt, that the Notes matured on December 1, 2022). 

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of the Reference Treasury Dealer Quotations
obtained by the Company for that Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or, if the Company is unable to obtain at least four such Reference Treasury Dealer Quotations, the average of all
Reference Treasury Dealer Quotations obtained by the Company. 
 “Disqualified Stock” means, with respect to any Person, any
capital stock of such Person which, by its terms, or by the terms of any security into which it is convertible or for which it is putable or exchangeable, or upon the happening of any event, matures or is mandatorily redeemable, other than as a
result of a change of control or asset sale, pursuant to a sinking fund obligation or otherwise, or is redeemable at the option of the holder thereof, other than as a result of a change of control or asset sale, in whole or in part, in each case
prior to the date 91 days after the earlier of the maturity date of the Notes or the date the Notes are no longer outstanding; provided that if such capital stock is issued pursuant to any plan for the benefit of employees of the Company or
its Subsidiaries or by any such plan to such employees, such capital stock shall not constitute Disqualified Stock solely because it may be required to be repurchased by the Company or its Subsidiaries in order to satisfy applicable statutory or
regulatory obligations. 
 “Equity Offering” means any public or private sale of common shares or preferred shares of the Company
(excluding Disqualified Stock), other than (a) public offerings with respect to the Company’s common shares registered on Form S-8 and (b) any sales to the Company or any of its Subsidiaries.

 “Independent Investment Banker” means BofA Securities, Inc. or Citigroup Global Markets Inc. and their respective successors,
as selected by the Company or, if such firms are unwilling or unable to select the applicable Comparable Treasury Issue or the applicable ratings scale for any Substitute Rating Agency, an independent investment banking institution of national
standing appointed by the Company. 
 “Reference Treasury Dealer” means BofA Securities, Inc. and its successors, and three other
independent investment banking institutions of national standing appointed by the Company (each, a “Primary Treasury Dealer”); provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the
Company shall substitute therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotations” means, with respect
to each Reference Treasury Dealer and any Redemption Date for the Notes, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted
in writing to the Independent Investment Banker by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding the Redemption Date. 

  
 9 

 “Treasury Rate” means, with respect to any Redemption Date, (i) the yield,
under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of
Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the
Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall
be interpolated or extrapolated from such yields on a straight-line basis, rounded to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such
yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding such Redemption Date. 

SECTION 4.02.    Purchase of Notes Upon a Change of Control Repurchase
Event. If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes as described under Section 4.01 above, the Company will be required to make an offer to each Holder of the Notes to
repurchase all or any part (in minimum principal amounts of $2,000 and in integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price (the “Purchase Price”) in cash equal to 101% of the
aggregate principal amount of the Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the
Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company will mail a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute
or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the payment date specified in the notice (the “Repurchase Date”), which date will be no earlier than 30 days and no later than 60 days
from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the payment
date specified in the notice. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and
regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase
Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached the Company’s obligations under the Change of Control Repurchase Event provisions of the Notes by
virtue of such conflict. 
 On the Repurchase Date following a Change of Control Repurchase Event, the Company will, to the extent lawful:

 (i)    accept for payment all the Notes or portions of the Notes properly tendered pursuant to the
Company’s offer; 

  
 10 

 (ii)    deposit with the Paying Agent an amount equal to
the aggregate Purchase Price in respect of all the Notes or portions of the Notes properly tendered; and 

(iii)    deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an
Officers’ Certificate stating the aggregate principal amount of Notes being purchased by the Company. 
 The Paying Agent will promptly
deliver to each Holder of Notes properly tendered, the Purchase Price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any
unpurchased portion of any Notes surrendered. 
 The Company will not be required to make an offer to repurchase the Notes upon a Change of
Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn
under its offer. 
 For purposes hereof, the following definitions are applicable: 

“Change of Control” means the occurrence of any one of the following: 

(i)    the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of
merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole to any Person (including any “person” (as that term is used in
Section 13(d)(3) of the Exchange Act)) other than to the Company or one of its Subsidiaries; 

(ii)    the consummation of any transaction (including, without limitation, any merger or consolidation)
the result of which is that any Person (including any “person” (as that term is used in Section 13(d)(3) of the Exchange Act)) becomes the “beneficial owner” (as defined in Rules 13d-3
and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of the Company, measured by voting power rather than number of shares; 

(iii)    the Company consolidates with, or merges with or into, any Person, or any Person consolidates
with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or such other Person is converted into or exchanged for cash, securities or other property, other than
any such transaction where the shares of the Voting Stock of the Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving Person immediately after
giving effect to such transaction; or 
 (iv)    the adoption of a plan relating to the liquidation or
dissolution of the Company. 
 “Change of Control Repurchase Event” means the occurrence of both a Change of Control and a
Ratings Event. 

  
 11 

 “Investment Grade” means a rating of Baa3 or better by Moody’s (or its
equivalent under any successor Rating Categories of Moody’s), a rating of BBB- or better by S&P (or its equivalent under any successor Rating Categories of S&P) and the equivalent Investment Grade
credit rating from any additional Rating Agency or Rating Agencies selected by the Company. 
 “Moody’s” means
Moody’s Investors Service Inc., and its successors. 
 “Rating Agency” means (1) each of Moody’s and S&P
and (2) if either of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the control of the Company, a Substitute Rating Agency thereof. 

“Rating Category” means (i) with respect to S&P, any of the following categories: BBB, BB, B, CCC, CC, C and D (or
equivalent successor categories); (ii) with respect to Moody’s, any of the following categories: Baa, Ba, B, Caa, Ca, C and D (or equivalent successor categories); and (iii) the equivalent of any such category of S&P or Moody’s
used by another Rating Agency. In determining whether the rating of the Notes has decreased by one or more gradations, gradations within Rating Categories (+ and - for S&P; 1, 2 and 3 for Moody’s; or the equivalent gradations for another
Rating Agency) shall be taken into account (e.g., with respect to S&P, a decline in a rating from BB+ to BB, as well as from BB- to B+, will constitute a decrease of one gradation). 

“Rating Date” means the date that is 60 days prior to the earlier of (i) a Change of Control or (ii) public notice
of the occurrence of a Change of Control or of the intention by the Company to effect a Change of Control. 
 “Ratings
Event” means the occurrence of the events described in (a) or (b) of this definition on, or within 60 days after the earlier of, (i) the occurrence of a Change of Control or (ii) public notice of the occurrence of a Change of
Control or the intention by the Company to effect a Change of Control (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies): (a) if the
Notes are rated by both Rating Agencies on the Rating Date as Investment Grade, the rating of the Notes shall be reduced so that the Notes are rated below Investment Grade by both Rating Agencies or (b) if the Notes are rated below Investment
Grade by at least one Rating Agency, the ratings of the Notes by both Rating Agencies shall be decreased by one or more gradations (including gradations within Rating Categories, as well as between Rating Categories) and the Notes are then rated
below Investment Grade by both Rating Agencies. 
 “S&P” means Standard & Poor’s, a division of The
McGraw-Hill Companies, Inc., and its successors. 
 “Voting Stock” of any specified “person” (as that term is
used in Section 13(d)(3) of the Exchange Act) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

ALLEGHENY TECHNOLOGIES INCORPORATED 

5.875% Senior Note due 2027 
  

	1.	 Principal and Interest. 

The Company promises to pay the principal of this Note on December 1, 2027. 

The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth on the face of this
Note, at the rate of 5.875% per annum. 
 Interest will be payable semiannually (to the Holders of record of the Notes at the close of
business on each Regular Record Date, as set forth on the face of this Note, immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing June 1, 2020. 

Interest on this Note will accrue from the most recent date to which interest has been paid on this Note (or, if there is no existing default
in the payment of interest and if this Note is authenticated between a Regular Record Date and the next Interest Payment Date, from such Interest Payment Date) or, if no interest has been paid, from November 22, 2019. Interest will be computed
on the basis of a 360-day year of twelve 30-day months. 
  

	2.	 Indenture. 

This Global Security is one of a duly authorized issue of securities of the Company (herein called the “Notes”) issued under the
Indenture, dated as of June 1, 2009 (the “Base Indenture”), between the Company and The Bank of New York Mellon, as Trustee (the “Trustee”), as heretofore supplemented, and as supplemented by the Sixth Supplemental
Indenture, dated as of November 22, 2019 (the “Supplemental Indenture”, and together with the Base Indenture as so supplemented, the “Indenture”), between the Company and the Trustee. Capitalized terms used herein are used
as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders
are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the
Indenture will control. 
 The Notes are general unsecured obligations of the Company. The Indenture limits the original aggregate principal
amount of the Notes to $350,000,000, but additional Notes may be issued pursuant to the Indenture, and the originally issued Notes and all such additional Notes vote together for all purposes as a single class. 

 

	3.	 Redemption and Repurchase; Discharge Prior to Redemption or Maturity. 

This Note is subject to redemption by the Company at any time, as further described in the Indenture. This Note is subject to repurchase by the
Company at the option of the holder upon the occurrence of a Change of Control Repurchase Event (as defined in the Supplemental Indenture). There is no sinking fund or mandatory redemption applicable to this Note. 

 If the Company deposits with the Trustee money or U.S. Government Securities sufficient to
pay the then Outstanding principal of, premium, if any, and accrued interest on the Notes to redemption or maturity, the Company may in certain circumstances be discharged from the Indenture and the Notes or may be discharged from certain of its
obligations under certain provisions of the Indenture. 
  

	4.	 Registered Form; Denominations; Transfer; Exchange. 

The Notes are in registered form without coupons in denominations of $2,000 principal amount and any multiple of $1,000 in excess thereof. A
Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Company or Security Registrar may require a Holder to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. Pursuant to the Indenture, there are certain periods during which the Company will not be required to issue, register the transfer of or exchange any Note or certain portions of a Note. 

 

	5.	 Defaults and Remedies. 

If an Event of Default (other than certain bankruptcy defaults), as defined in the Indenture, occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Notes then Outstanding may declare all the Notes to be due and payable. If certain bankruptcy defaults with respect to the Company occur and are continuing, the Notes automatically become due and
payable. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a
majority in principal amount of the Notes then Outstanding may direct the Trustee in its exercise of remedies. 
  

	6.	 Amendment and Waiver. 

Subject to certain exceptions, the Indenture and the Notes may be amended, or default may be waived, with the consent of the Holders of a
majority in principal amount of the Outstanding Notes. Without notice to or the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency. 
  

	7.	 Authentication. 

This Note is not valid until the Trustee signs the certificate of authentication on the other side of this Note. 

 

	8.	 Abbreviations. 

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the
entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A/ (= Uniform Gifts to Minors Act). 

 The Company will furnish a copy of the Indenture to any Holder upon written request and without charge.
