    LIMESTONE BANCORP, INC.

     

    5.75% FIXED-TO-FLOATING RATE SUBORDINATED NOTE DUE 2029

     

    THIS OBLIGATION IS NOT A DEPOSIT AND IS NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY OR FUND.

     

    1.               Indenture; Holders.  This Subordinated Note is one of a duly authorized issue of notes of Limestone Bancorp,
      Inc., a Kentucky corporation (the “Company”), designated as the “5.75% Fixed-to-Floating Rate Subordinated Notes due 2029” (the “Subordinated Notes”) in an aggregate principal amount of $17,000,000 and initially issued on July 23, 2019.
      The Company has issued this Subordinated Note under that certain Indenture dated as of July 23, 2019, as the same may be amended or supplemented from time to time (“Indenture”), between the Company and Wilmington Trust, National Association,
      as Trustee. All capitalized terms not otherwise defined in this Subordinated Note will have the meanings assigned to them in the Indenture. The terms of this Subordinated Note include those stated in the Indenture and those made part of the Indenture
      by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). This Subordinated Note is subject to all such terms, and the Holder (as defined below) is referred to the Indenture and the Trust Indenture Act for a
      statement of such terms. To the extent any provision of this Subordinated Note irreconcilably conflicts with the express provisions of the Indenture, the provisions of the Indenture will govern and be controlling.

     

    
      - 3 -

      
        


    

     

    

    Payment.  The Company, for value received, promises to pay to Cede & Co., or its registered assigns (the “Holder”), as nominee of The Depository Trust Company, the principal sum of
      [●] MILLION DOLLARS (U.S.) [($●)], plus accrued but unpaid interest on July 31, 2029 (“Stated Maturity”) and to pay interest thereon (i) from and including the original issue date of the Subordinated Notes to but excluding July 31, 2024, at
      the rate of 5.75% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months and payable semi-annually in arrears on January 31 and July 31 of each year (each, a “Fixed Interest Payment Date”), beginning January 31,
      2020 and ending on July 31, 2024, and (ii) from and including July 31, 2024 to but excluding the Stated Maturity or the early redemption date contemplated by Section 5 of this Subordinated Note, at the rate per annum, reset quarterly, equal
      to Three-Month LIBOR determined on the LIBOR Determination Date (as defined below) of the applicable Interest Period plus 395 basis points, computed on the basis of a 360-day year and the actual number of days elapsed and payable quarterly in arrears
      on January 31, April 30, July 31 and October 31 of each year (each, a “Floating Interest Payment Date”). An “Interest Payment Date” is either a Fixed Interest Payment Date or a Floating Interest Payment Date, as applicable. “Three-Month LIBOR”
      means, for any Interest Period, the offered rate for deposits in U.S. dollars having a maturity of three months that appears on the Designated LIBOR Page as of 11:00 a.m., London time, on the LIBOR Determination Date related to such Interest Period.
      If such rate does not appear on such page at such time, then the Calculation Agent will request the principal London office of each of four major reference banks in the London interbank market, selected by the Company for this purpose and whose names
      and contact information will be provided by the Company to the Calculation Agent, to provide such bank’s offered quotation to prime banks in the London interbank market for deposits in U.S. dollars with a term of three months as of 11:00 a.m., London
      time, on such Determination Date and in a principal amount equal to an amount for a single transaction in U.S. dollars in the relevant market at the relevant time as determined by the Company and provided to the Calculation Agent (a “Representative



        Amount”). If at least two such quotations are so provided, Three-Month LIBOR for the Interest Period related to such LIBOR Determination Date will be the arithmetic mean of such quotations. If fewer than two such quotations are provided, the
      Calculation Agent will request each of three major banks in the City of New York selected by the Company for this purpose and whose names and contact information will be provided by the Company to the Calculation Agent, to provide such bank’s rate
      for loans in U.S. dollars to leading European banks with a term of three months as of approximately 11:00 a.m., New York City time, on such LIBOR Determination Date and in a Representative Amount. If at least two such rates are so provided,
      Three-Month LIBOR for the Interest Period related to such LIBOR Determination Date will be the arithmetic mean of such quotations. If fewer than two such rates are so provided, then Three-Month LIBOR for the Interest Period related to such LIBOR
      Determination Date will be set to equal the Three-Month LIBOR for the immediately preceding Interest Period. All percentages used in or resulting from any calculation of Three-Month LIBOR will be rounded, if necessary, to the nearest one
      hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. Notwithstanding the foregoing, in the event that Three-Month LIBOR as determined in accordance with this definition is less than zero, Three-Month LIBOR for such
      Interest Period shall be deemed to be zero.

     

    In addition, if the Calculation Agent determines that Three-Month LIBOR is not published on the Designated LIBOR Page, then the Company may determine and provide to the Calculation Agent in writing
      whether to calculate the relevant interest rate using a substitute or successor base rate that the Company has determined in its sole discretion is most comparable to Three-Month LIBOR or is an industry-accepted substitute or successor base rate, and
      the Calculation Agent will use that substitute or successor base rate as directed by the Company in writing. If a substitute or successor base rate has been determined in accordance with the foregoing, the Company in its sole discretion may determine
      what business day convention to use, the definition of business day, the 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 Three-Month LIBOR, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate.

     

    For purposes hereof:

     

    “Designated LIBOR Page” means the display on Bloomberg Page BBAM1 (or any successor or substitute page of such service, or any successor to such service selected by the Company), for the purpose of displaying
      the London interbank rates for U.S. dollar deposits of major banks.

     

    “LIBOR Administrator” means, collectively, the ICE Benchmark Administration Limited (“ICE”) or its successor, or such other entity assuming the responsibility of ICE or its successor in calculating London
      inter-bank offered rates in the event ICE or its successor no longer does so.

     

    “LIBOR Determination Date” means the second London Banking Day (as defined below) immediately preceding the first day of the relevant Interest Period.

     

    “London Banking Day” means any day on which commercial banks are open for business (including dealings in deposits in US dollars) in London, England.

     

    
      - 4 -

      
        


    

     

    

    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 will 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 Company will pay interest on this Subordinated Note to the Person who is the registered Holder at the close of business on the fifteenth calendar day prior to the applicable Interest Payment
      Date, except as provided in Section 2.10 of the Indenture with respect to Defaulted Interest. This Subordinated Note will be payable as to principal and interest at the office or agency of the Paying Agent, or, at the option of the Company,
      payment of interest may be made by check delivered to the Holder at its address set forth in the Subordinated Note Register or by wire transfer to an account appropriately designated by the Person entitled to payment; provided, that the Paying Agent
      will have received written notice of such account designation at least five Business Days prior to the date of such payment (subject to surrender of this Subordinated Note in the case of a payment of interest at Maturity).

     

    2.             Paying Agent and Registrar.  Wilmington Trust, National Association, a national banking association, the Trustee (“Trustee”)



      under the Indenture, will act as the initial Paying Agent and Registrar through its offices presently located at 1100 North Market Street, Wilmington, DE 19890. The Company may change any Paying Agent or Registrar without notice to any Holder. The
      Company or any of its Subsidiaries may act in any such capacity.

     

    3.               Subordination. The indebtedness of the Company evidenced by this Subordinated Note, including the principal
      thereof and interest thereon, is, to the extent and in the manner set forth in the Indenture, subordinate and junior in right of payment and upon the Company’s liquidation to obligations of the Company constituting the Senior Indebtedness (as defined
      in the Indenture) on the terms and subject to the terms and conditions as provided and set forth in Article XI of the Indenture and will rank pari passu in right of payment and upon the Company’s liquidation
      with the Company’s existing and all future indebtedness the terms of which provide that such indebtedness ranks equally with promissory notes, bonds, debentures and other evidences of indebtedness of types that include the Subordinated Notes. Holder,
      by the acceptance of this Subordinated Note, agrees to and will be bound by such provisions of the Indenture and authorizes and directs the Trustee on his behalf to take such actions as may be necessary or appropriate to effectuate the subordination
      so provided.

     

    4.               Redemption.

     

    (a)            The Company may, at its option, on any Interest Payment Date on or after July 31, 2024, redeem this Subordinated Note, in whole or in part,
      without premium or penalty, but in all cases in a principal amount in minimum denominations of $2,000 and any integral multiples of $1,000 in excess thereof. In addition, the Company may redeem all, but not 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. Any redemption of this Subordinated Note shall be subject to the prior approval of the Board of Governors of the Federal Reserve System (or its designee) or
      any successor agency, and any other banking regulatory agency, to the extent such approval shall then be required by law, regulation or policy. This Subordinated Note is not subject to redemption at the option of the Holder. The Redemption Price with
      respect to any redemption permitted under this Indenture will be equal to 100% of the principal amount of this Subordinated Note, or portion thereof, to be redeemed, plus accrued but unpaid interest thereon to, but excluding, the Redemption Date.

     

    
      - 5 -

      
        


    

     

    

    (b)            If less than the then outstanding principal amount of this Subordinated Note is redeemed, (i) a new 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 Holders. For purposes of clarity, upon a partial redemption, a like percentage of the principal amount
      of every Subordinated Note held by every Holder shall be redeemed.

     

    (c)            Effectiveness of Redemption.  If notice of redemption has been duly given and notwithstanding that any Subordinated
      Notes so called for redemption have not been surrendered for cancellation, on and after the Redemption Date interest shall cease to accrue on all Subordinated Notes so called for redemption, all Subordinated Notes so called for redemption shall no
      longer be deemed outstanding and all rights with respect to such Subordinated Notes shall forthwith on such Redemption Date cease and terminate (unless the Company shall default in the payment of the redemption price), except only the right of the
      Holder thereof to receive the amount payable on such redemption, without interest.

     

    5.             Events of Default; Acceleration.  An “Event of Default” means any one of the events described in Section
        4.01 of the Indenture. If an Event of Default described in Section 4.01(1) or Section 4.01(2) of the Indenture occurs, then the principal amount of all of the Outstanding Subordinated Notes, and accrued and unpaid interest, if
      any, on all Outstanding Subordinated Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or the Holder, and 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
        4.01(1) or Section 4.01(2) of the Indenture, neither the Trustee nor the Holder may accelerate the Maturity of the Subordinated Notes and make the principal of, and any accrued and unpaid interest on, the Subordinated Notes, immediately
      due and payable. If any Event of Default occurs and is continuing, the Trustee may also pursue any other available remedy to collect the payment of principal of, and interest on, the Subordinated Notes then due and payable or to enforce the
      performance of any provision of the Subordinated Notes or the Indenture.

     

    6.               Failure to Make Payments.  If the Company fails to make any payment of interest on this Subordinated Note when
      such interest becomes due and payable and such default continues for a period of 30 days, or if the Company fails to make any payment of the principal of this Subordinated Note when such principal becomes due and payable, the Company will, upon
      demand of the Trustee, pay to the Trustee, for the benefit of the Holder, the whole amount then due and payable with respect to this Subordinated Note, with interest upon the overdue principal, any premium and, to the extent permitted by applicable
      law, upon any overdue installments of interest at the rate or respective rates, as the case may be, provided for or with respect to this Subordinated Note or, if no such rate or rates are so provided, at the rate or respective rates, as the case may
      be, of interest borne by this Subordinated Note.

     

    
      - 6 -

      
        


    

     

    

    Upon an Event of Default, the Company may not declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company’s
      capital stock, make any payment of principal or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company that rank equal with or junior to this Subordinated Note, or make any payments under any guarantee that
      ranks equal with or junior to this Subordinated Note, 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 Company’s common stock; (ii) any declaration of a
      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
      Company’s capital stock or the exchange or conversion of one class or series of Company’s capital stock for another class or series of Company’s capital stock; (iv) the purchase of fractional interests in shares of Company’s capital stock in
      accordance with the conversion or exchange provisions of such capital stock or the security being converted or exchanged; or (v) purchases of any class of Company’s common stock related to the issuance of common stock or rights under any benefit
      plans for Company’s directors, officers or employees or any of Company’s dividend reinvestment plans.

     

    7.              Denominations, Transfer, Exchange.  The Subordinated Notes are issuable only in registered form without interest
      coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of this Subordinated Note may be registered and this Subordinated Note may be exchanged as provided in the Indenture. The Registrar may
      require the Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require the Holder to pay any taxes and fees required by law or permitted by the Indenture.

     

    8.               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 Holder requesting such transfer or exchange.

     

    9.               Persons Deemed Owners.  The Company and the Trustee and any agent of the Company or the Trustee may treat the
      Person in whose name this Subordinated Note is registered as the owner hereof for all purposes, whether or not this Subordinated Note is overdue, and neither the Company, the Trustee nor any such agent will be affected by notice to the contrary.

     

    10.             Amendments; Waivers.  The Indenture permits, with certain exceptions as therein provided, the amendment thereof
      and the modification of the rights and obligations of the Company and the rights of the Holders of the Subordinated Notes at any time by the Company and the Trustee with the consent of the holders of a majority in principal amount of the then
      Outstanding Subordinated Notes. The Indenture also contains provisions permitting the holders of specified percentages in principal amount of the then Outstanding Subordinated Notes, on behalf of the holders of all Subordinated Notes, to waive
      certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Subordinated Note will be conclusive and binding upon such Holder and upon all future holders of this Subordinated Note and of any
      Subordinated Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Subordinated Note.

    11.            No Impairment.  No reference herein to the Indenture and no provision of this Subordinated Note or of the Indenture
      will alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest (if any) on this Subordinated Note at the times, place and rate as herein prescribed.

     

    12.             Sinking Fund; Convertibility.  This Subordinated Note is not entitled to the benefit of any sinking fund. This

    13.           No Recourse Against Others.  No recourse under or upon any obligation, covenant or agreement contained in the
      Indenture or in this Subordinated Note, or for any claim based thereon or otherwise in respect thereof, will be had against any past, present or future shareholder, employee, officer, or director, as such, of the Company or of any predecessor or
      successor, either directly or through the Company or any predecessor or successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such
      liability being expressly waived and released by the acceptance of this Subordinated Note by the Holder and as part of the consideration for the issuance of this Subordinated Note.

     

    14.             Authentication.  This Subordinated Note will not be valid until authenticated by the manual signature of the
      Trustee or an Authenticating Agent.
