  Form of Common Stock Warrant
    Agreement

   

  This
        Common Stock Warrant Agreement (this “Agreement”), dated as of [●], between Kronos
        Bio, Inc., a Delaware corporation (the “Company”), and [●], a [corporation] [national
    banking association] organized and existing under the laws of [●] and having a corporate trust office in [●], as warrant
    agent (the “Warrant Agent”).

   

  Whereas,
    the Company proposes to sell [If Warrants are sold with other securities —[title of such other
      securities being offered] (the “Other Securities”) with] warrant certificates evidencing one or
    more warrants (the “Warrants” or, individually, a “Warrant”) representing the
    right to purchase Common Stock of the Company, par value $0.001 per share (the “Warrant Securities”),
    such warrant certificates and other warrant certificates issued pursuant to this Agreement being herein called the “Warrant
        Certificates”; and

   

  Whereas,
      the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing so to act, in
    connection with the issuance, registration, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this
    Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the terms and conditions
    on which they may be issued, registered, transferred, exchanged, exercised and replaced.

   

  Now
        Therefore, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree
    as follows:

   

  Article
    1

    

    ISSUANCE OF WARRANTS AND EXECUTION AND

    DELIVERY OF WARRANT CERTIFICATES

   

  1.1          Issuance of Warrants. [If Warrants alone —Upon
    issuance, each Warrant Certificate shall evidence
    one or more Warrants.] [If Other Securities and Warrants —Warrant Certificates will be issued in connection
    with the issuance of the Other Securities but shall be separately transferable and each Warrant Certificate shall evidence one
    or more Warrants.] Each Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein,
    to purchase one Warrant Security. [If Other Securities and Warrants —Warrant Certificates will be issued with
    the Other Securities and each Warrant Certificate will evidence [●] Warrants for each [$[●] principal amount] [[●]
    shares] of Other Securities issued.]

   

  1.2          Execution and Delivery of Warrant Certificates. Each Warrant
    Certificate, whenever issued, shall be in registered form
    substantially in the form set forth in Exhibit A hereto, shall be dated the date of its countersignature by the Warrant
    Agent and may have such letters, numbers, or other marks of identification or designation and such legends or endorsements printed,
    lithographed or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive
    evidence of such approval) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with
    any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange on which
    the Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf of the Company by any of
    its present or future chief executive officers, presidents, senior vice presidents, vice presidents, chief financial officers,
    chief legal officers, treasurers, assistant treasurers, controllers, assistant controllers, secretaries or assistant secretaries
    under its corporate seal reproduced thereon. Such signatures may be manual or facsimile signatures of such authorized officers
    and may be imprinted or otherwise reproduced on the Warrant Certificates. The seal of the Company may be in the form of a facsimile
    thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Warrant Certificates.

   

  
    1

    
      

    

  

   

  No Warrant Certificate
    shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant Certificate has been
    countersigned by the manual signature of the Warrant Agent. Such signature by the Warrant Agent upon any Warrant Certificate executed
    by the Company shall be conclusive evidence that the Warrant Certificate so countersigned has been duly issued hereunder.

   

  In case any officer
    of the Company who shall have signed any of the Warrant Certificates either manually or by facsimile signature shall cease to be
    such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent, such Warrant
    Certificates may be countersigned and delivered notwithstanding that the person who signed such Warrant Certificates ceased to
    be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual
    date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution
    of this Agreement any such person was not such officer.

   

  The term “holder”
    or “holder of a Warrant Certificate” as used herein shall mean any person in whose name at the time any
    Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose.

   

  1.3          Issuance of Warrant Certificates. Warrant Certificates
    evidencing the right to purchase Warrant Securities may be executed
    by the Company and delivered to the Warrant Agent upon the execution of this Agreement or from time to time thereafter. The Warrant
    Agent shall, upon receipt of Warrant Certificates duly executed on behalf of the Company, countersign such Warrant Certificates
    and shall deliver such Warrant Certificates to or upon the order of the Company.

    WARRANT PRICE, DURATION AND EXERCISE OF WARRANTS

   

  2.1          Warrant Price. During the period specified in Section 2.2,
    each Warrant shall, subject to the terms of this Agreement
    and the applicable Warrant Certificate, entitle the holder thereof to purchase the number of Warrant Securities specified in the
    applicable Warrant Certificate at an exercise price of $[●] per Warrant Security, subject to adjustment upon the occurrence
    of certain events, as hereinafter provided. Such purchase price per Warrant Security is referred to in this Agreement as the “Warrant
        Price.”

   

  2.2          Duration of Warrants. Each Warrant may be exercised in whole
    or in part at any time, as specified herein, on or after
    [the date thereof] [●] and at or before [●] p.m., [City] time, on [●] or such later date as the Company may designate
    by notice to the Warrant Agent and the holders of Warrant Certificates mailed to their addresses as set forth in the record books
    of the Warrant Agent (the “Expiration Date”). Each Warrant not exercised at or before [●] p.m.,
    [City] time, on the Expiration Date shall become void, and all rights of the holder of the Warrant Certificate evidencing such
    Warrant under this Agreement shall cease.

   

  
    2

    
      

    

  

   

  2.3          Exercise of Warrants.

   

  (a)           During the period specified in Section 2.2, the Warrants may be
    exercised to purchase a whole number of Warrant Securities
    in registered form by providing certain information as set forth on the reverse side of the Warrant Certificate and by paying in
    full, in lawful money of the United States of America, [in cash or by certified check or official bank check in New York Clearing
    House funds] [by bank wire transfer in immediately available funds] the Warrant Price for each Warrant Security with respect to
    which a Warrant is being exercised to the Warrant Agent at its corporate trust office, provided that such exercise is subject to
    receipt within five business days of such payment by the Warrant Agent of the Warrant Certificate with the form of election to
    purchase Warrant Securities set forth on the reverse side of the Warrant Certificate properly completed and duly executed. The
    date on which payment in full of the Warrant Price is received by the Warrant Agent shall, subject to receipt of the Warrant Certificate
    as aforesaid, be deemed to be the date on which the Warrant is exercised; provided, however, that if, at the date of receipt of
    such Warrant Certificates and payment in full of the Warrant Price, the transfer books for the Warrant Securities purchasable upon
    the exercise of such Warrants shall be closed, no such receipt of such Warrant Certificates and no such payment of such Warrant
    Price shall be effective to constitute the person so designated to be named as the holder of record of such Warrant Securities
    on such date, but shall be effective to constitute such person as the holder of record of such Warrant Securities for all purposes
    at the opening of business on the next succeeding day on which the transfer books for the Warrant Securities purchasable upon the
    exercise of such Warrants shall be opened, and the certificates for the Warrant Securities in respect of which such Warrants are
    then exercised shall be issuable as of the date on such next succeeding day on which the transfer books shall next be opened, and
    until such date the Company shall be under no duty to deliver any certificate for such Warrant Securities. The Warrant Agent shall
    deposit all funds received by it in payment of the Warrant Price in an account of the Company maintained with it and shall advise
    the Company by telephone at the end of each day on which a payment for the exercise of Warrants is received of the amount so deposited
    to its account. The Warrant Agent shall promptly confirm such telephone advice to the Company in writing.

   

  (b)           The Warrant Agent shall, from time to time, as promptly as
    practicable, advise the Company of (i) the number of Warrant
    Securities with respect to which Warrants were exercised, (ii) the instructions of each holder of the Warrant Certificates evidencing
    such Warrants with respect to delivery of the Warrant Securities to which such holder is entitled upon such exercise, (iii) delivery
    of Warrant Certificates evidencing the balance, if any, of the Warrants for the remaining Warrant Securities after such exercise,
    and (iv) such other information as the Company shall reasonably require.

   

  (c)           As soon as practicable after the exercise of any Warrant, the
    Company shall issue to or upon the order of the holder
    of the Warrant Certificate evidencing such Warrant the Warrant Securities to which such holder is entitled, in fully registered
    form, registered in such name or names as may be directed by such holder. If fewer than all of the Warrants evidenced by such Warrant
    Certificate are exercised, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign
    and deliver, a new Warrant Certificate evidencing Warrants for the number of Warrant Securities remaining unexercised.

   

  (d)           The Company shall not be required to pay any stamp or other tax
    or other governmental charge required to be paid in
    connection with any transfer involved in the issue of the Warrant Securities, and in the event that any such transfer is involved,
    the Company shall not be required to issue or deliver any Warrant Security until such tax or other charge shall have been paid
    or it has been established to the Company’s satisfaction that no such tax or other charge is due.

   

  (e)           Prior to the issuance of any Warrants there shall have been
    reserved, and the Company shall at all times through the
    Expiration Date keep reserved, out of its authorized but unissued Warrant Securities, a number of shares sufficient to provide
    for the exercise of the Warrants.

    OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF

    WARRANT CERTIFICATES

   

  3.1          No Rights as Warrant Securityholder Conferred by Warrants or
      Warrant Certificates. No Warrant Certificate or Warrant
    evidenced thereby shall entitle the holder thereof to any of the rights of a holder of Warrant Securities, including, without limitation,
    the right to receive the payment of dividends or distributions, if any, on the Warrant Securities or to exercise any voting rights,
    except to the extent expressly set forth in this Agreement or the applicable Warrant Certificate.

   

  3.2          Lost, Stolen, Mutilated or Destroyed Warrant Certificates. Upon
    receipt by the Warrant Agent of evidence reasonably
    satisfactory to it and the Company of the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate
    and/or indemnity reasonably satisfactory to the Warrant Agent and the Company and, in the case of mutilation, upon surrender of
    the mutilated Warrant Certificate to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant
    Agent that such Warrant Certificate has been acquired by a bona fide purchaser, the Company shall execute, and an authorized officer
    of the Warrant Agent shall manually countersign and deliver, in exchange for or in lieu of the lost, stolen, destroyed or mutilated
    Warrant Certificate, a new Warrant Certificate of the same tenor and evidencing Warrants for a like number of Warrant Securities.
    Upon the issuance of any new Warrant Certificate under this Section 3.2, the Company may require the payment of a sum sufficient
    to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees
    and expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant
    to this Section 3.2 in lieu of any lost, stolen or destroyed Warrant Certificate shall represent an additional contractual obligation
    of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and
    shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly
    executed and delivered hereunder. The provisions of this Section 3.2 are exclusive and shall preclude (to the extent lawful) all
    other rights and remedies with respect to the replacement of mutilated, lost, stolen or destroyed Warrant Certificates.

   

  3.3          Holder of Warrant Certificate May Enforce Rights. Notwithstanding
    any of the provisions of this Agreement, any holder
    of a Warrant Certificate, without the consent of the Warrant Agent, the holder of any Warrant Securities or the holder of any other
    Warrant Certificate, may, in such holder’s own behalf and for such holder’s own benefit, enforce, and may institute
    and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such holder’s
    right to exercise the Warrants evidenced by such holder’s Warrant Certificate in the manner provided in such holder’s
    Warrant Certificate and in this Agreement.

   

  3.4          Adjustments.

   

  (a)           In case the Company shall at any time subdivide its outstanding
    shares of Common Stock into a greater number of shares,
    the Warrant Price in effect immediately prior to such subdivision shall be proportionately reduced and the number of Warrant Securities
    purchasable under the Warrants shall be proportionately increased. Conversely, in case the outstanding shares of Common Stock of
    the Company shall be combined into a smaller number of shares, the Warrant Price in effect immediately prior to such combination
    shall be proportionately increased and the number of Warrant Securities purchasable under the Warrants shall be proportionately
    decreased.

   

  
    4

    
      

    

  

   

  (b)           If at any time or from time to time the holders of Common Stock
    (or any shares of stock or other securities at the time
    receivable upon the exercise of the Warrants) shall have received or become entitled to receive, without payment therefor,

   

  (i)           Common Stock or any shares of stock or other securities which
    are at any time directly or indirectly convertible into
    or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing
    by way of dividend or other distribution;

   

  (ii)          any cash paid or payable otherwise than as a cash dividend
    paid or payable out of the Company’s current or retained
    earnings;

   

  (iii)         any evidence of the Company’s indebtedness or rights to
    subscribe for or purchase the Company’s indebtedness;
    or

   

  (iv)          Common Stock or additional stock or other securities or
    property (including cash) by way of spinoff, split-up, reclassification,
    combination of shares or similar corporate rearrangement (other than shares of Common Stock issued as a stock split or adjustments
    in respect of which shall be covered by the terms of Section 3.4(a) above), then and in each such case, the holder of each Warrant
    shall, upon the exercise of the Warrant, be entitled to receive, in addition to the number of Warrant Securities receivable thereupon,
    and without payment of any additional consideration therefore, the amount of stock and other securities and property (including
    cash and indebtedness or rights to subscribe for or purchase indebtedness) which such holder would hold on the date of such exercise
    had such holder been the holder of record of such Warrant Securities as of the date on which holders of Common Stock received or
    became entitled to receive such shares or all other additional stock and other securities and property.

   

  (c)           In case of (i) any reclassification, capital reorganization, or
    change in the Common Stock of the Company (other than
    as a result of a subdivision, combination, or stock dividend provided for in Section 3.4(a) or Section 3.4(b) above), (ii)
    share exchange, merger or similar transaction of the Company with or into another person or entity (other than a share exchange,
    merger or similar transaction in which the Company is the acquiring or surviving corporation and which does not result in any change
    in the Common Stock other than the issuance of additional shares of Common Stock) or (iii) the sale, exchange, lease, transfer
    or other disposition of all or substantially all of the properties and assets of the Company as an entirety (in any such case,
    a “Reorganization Event”), then, as a condition of such Reorganization Event, lawful provisions shall
    be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the holders of
    the Warrants, so that the holders of the Warrants shall have the right at any time prior to the expiration of the Warrants to purchase,
    at a total price equal to that payable upon the exercise of the Warrants, the kind and amount of shares of stock and other securities
    and property receivable in connection with such Reorganization Event by a holder of the same number of Warrant Securities as were
    purchasable by the holders of the Warrants immediately prior to such Reorganization Event. In any such case appropriate provisions
    shall be made with respect to the rights and interests of the holders of the Warrants so that the provisions hereof shall thereafter
    be applicable with respect to any shares of stock or other securities and property deliverable upon exercise the Warrants, and
    appropriate adjustments shall be made to the Warrant Price payable hereunder provided the aggregate purchase price shall remain
    the same. In the case of any transaction described in clauses (ii) and (iii) above, the Company shall thereupon be relieved of
    any further obligation hereunder or under the Warrants, and the Company as the predecessor corporation may thereupon or at any
    time thereafter be dissolved, wound up or liquidated. Such successor or assuming entity thereupon may cause to be signed, and may
    issue either in its own name or in the name of the Company, any or all of the Warrants issuable hereunder which heretofore shall
    not have been signed by the Company, and may execute and deliver securities in its own name, in fulfillment of its obligations
    to deliver Warrant Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the same legal
    rank and benefit under this Agreement as the Warrants theretofore or thereafter issued in accordance with the terms of this Agreement
    as though all of such Warrants had been issued at the date of the execution hereof. In any case of any such Reorganization Event,
    such changes in phraseology and form (but not in substance) may be made in the Warrants thereafter to be issued as may be appropriate.
    The Warrant Agent may receive a written opinion of legal counsel as conclusive evidence that any such Reorganization Event complies
    with the provisions of this Section 3.4.

   

  
    5

    
      

    

  

   

  (d)           The Company may, at its option, at any time until the
    Expiration Date, reduce the then current Warrant Price to any
    amount deemed appropriate by the Board of Directors of the Company for any period not exceeding twenty consecutive days (as evidenced
    in a resolution adopted by such Board of Directors), but only upon giving the notices required by Section 3.5 at least ten days
    prior to taking such action.

   

  (e)           Except as herein otherwise expressly provided, no adjustment in
    the Warrant Price shall be made by reason of the issuance
    of shares of Common Stock, or securities convertible into or exchangeable for shares of Common Stock, or securities carrying the
    right to purchase any of the foregoing or for any other reason whatsoever.

   

  (f)            No fractional Warrant Securities shall be issued upon the
    exercise of Warrants. If more than one Warrant shall be exercised
    at one time by the same holder, the number of full Warrant Securities which shall be issuable upon such exercise shall be computed
    on the basis of the aggregate number of Warrant Securities purchased pursuant to the Warrants so exercised. Instead of any fractional
    Warrant Security which would otherwise be issuable upon exercise of any Warrant, the Company shall pay a cash adjustment in respect
    of such fraction in an amount equal to the same fraction of the last reported sale price (or bid price if there were no sales)
    per Warrant Security, in either case as reported on the principal registered national securities exchange on which the Warrant
    Securities are listed or admitted to trading on the business day that next precedes the day of exercise or, if the Warrant Securities
    are not then listed or admitted to trading on any registered national securities exchange, the average of the closing high bid
    and low asked prices as reported on the OTC Bulletin Board Service (the “OTC Bulletin Board”) operated
    by the Financial Industry Regulatory Authority, Inc. (“FINRA” ) or, if not available on the OTC Bulletin
    Board, then the average of the closing high bid and low asked prices as reported on any other U.S. quotation medium or inter-dealer
    quotation system on such date, or if on any such date the Warrant Securities are not listed or admitted to trading on a registered
    national securities exchange, are not included in the OTC Bulletin Board, and are not quoted on any other U.S. quotation medium
    or inter-dealer quotation system, an amount equal to the same fraction of the average of the closing bid and asked prices as furnished
    by any FINRA member firm selected from time to time by the Company for that purpose at the close of business on the business day
    that next precedes the day of exercise.

   

  (g)           Whenever the Warrant Price then in effect is adjusted as herein
    provided, the Company shall mail to each holder of the
    Warrants at such holder’s address as it shall appear on the books of the Company a statement setting forth the adjusted Warrant
    Price then and thereafter effective under the provisions hereof, together with the facts, in reasonable detail, upon which such
    adjustment is based.

   

  (h)           Notwithstanding anything to the contrary herein, in no event
    shall the Warrant Price, as adjusted in accordance with
    the terms hereof, be less than the par value per share of Common Stock.

   

  
    6

    
      

    

  

   

  3.5          Notice to Warrantholders. In case the Company shall (a)
    effect any dividend or distribution described in Section 3.4(b),
    (b) effect any Reorganization Event, (c) make any distribution on or in respect of the Common Stock in connection with the dissolution,
    liquidation or winding up of the Company, or (d) reduce the then current Warrant Price pursuant to Section 3.4(d), then the Company
    shall mail to each holder of Warrants at such holder’s address as it shall appear on the books of the Warrant Agent, at least
    ten days prior to the applicable date hereinafter specified, a notice stating (x) the record date for such dividend or distribution,
    or, if a record is not to be taken, the date as of which the holders of record of Common Stock that will be entitled to such dividend
    or distribution are to be determined, (y) the date on which such Reorganization Event, dissolution, liquidation or winding up is
    expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled
    to exchange their shares of Common Stock for securities or other property deliverable upon such Reorganization Event, dissolution,
    liquidation or winding up, or (z) the first date on which the then current Warrant Price shall be reduced pursuant to Section 3.4(d).
    No failure to mail such notice nor any defect therein or in the mailing thereof shall affect any such transaction or any adjustment
    in the Warrant Price required by Section 3.4.

   

  3.6          [If the Warrants are Subject to Acceleration by the Company,
    Insert — Acceleration of Warrants by the Company.

   

  (a)           At any time on or after [●], the Company shall have the right
    to accelerate any or all Warrants at any time by
    causing them to expire at the close of business on the day next preceding a specified date (the “Acceleration Date”),
    if the Market Price (as hereinafter defined) of the Common Stock equals or exceeds [●] percent ([●]%) of the then effective
    Warrant Price on any twenty Trading Days (as hereinafter defined) within a period of thirty consecutive Trading Days ending no
    more than five Trading Days prior to the date on which the Company gives notice to the Warrant Agent of its election to accelerate
    the Warrants.

   

  (b)           (b) “Market Price” for each Trading Day shall
    be, if the Common Stock is listed or admitted
    to trading on any registered national securities exchange, the last reported sale price, regular way (or, if no such price is reported,
    the average of the reported closing bid and asked prices, regular way) of Common Stock, in either case as reported on the principal
    registered national securities exchange on which the Common Stock is listed or admitted to trading or, if not listed or admitted
    to trading on any registered national securities exchange, the average of the closing high bid and low asked prices as reported
    on the OTC Bulletin Board operated by FINRA, or if not available on the OTC Bulletin Board, then the average of the closing high
    bid and low asked prices as reported on any other U.S. quotation medium or inter-dealer quotation system, or if on any such date
    the shares of Common Stock are not listed or admitted to trading on a registered national securities exchange, are not included
    in the OTC Bulletin Board, and are not quoted on any other U.S. quotation medium or inter-dealer quotation system, the average
    of the closing bid and asked prices as furnished by any FINRA member firm selected from time to time by the Company for that purpose.
    “Trading Day” shall be each Monday through Friday, other than any day on which securities are not traded in the system
    or on the exchange that is the principal market for the Common Stock, as determined by the Board of Directors of the Company. In
    the event of an acceleration of less than all of the Warrants, the Warrant Agent shall select the Warrants to be accelerated by
    lot, pro rata or in such other manner as it deems, in its discretion, to be fair and appropriate.

   

  (c)           Notice of an acceleration specifying the Acceleration Date
    shall be sent by mail first class, postage prepaid, to each
    registered holder of a Warrant Certificate representing a Warrant accelerated at such holder’s address appearing on the books
    of the Warrant Agent not more than sixty days nor less than thirty days before the Acceleration Date. Such notice of an acceleration
    also shall be given no more than twenty days, and no less than ten days, prior to the mailing of notice to registered holders of
    Warrants pursuant to this Section 3.6, by publication at least once in a newspaper of general circulation in the City of New York.

   

  
    7

    
      

    

  

   

  (d)           Any Warrant accelerated may be exercised until [●] p.m., [City]
    time, on the business day next preceding the Acceleration
    Date. The Warrant Price shall be payable as provided in Section 2.]

    EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES

   

  4.1          Exchange and Transfer of Warrant Certificates. Upon surrender
    at the corporate trust office of the Warrant Agent, Warrant
    Certificates evidencing Warrants may be exchanged for Warrant Certificates in other denominations evidencing such Warrants or the
    transfer thereof may be registered in whole or in part; provided that such other Warrant Certificates evidence Warrants for the
    same aggregate number of Warrant Securities as the Warrant Certificates so surrendered. The Warrant Agent shall keep, at its corporate
    trust office, books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates
    and exchanges and transfers of outstanding Warrant Certificates, upon surrender of the Warrant Certificates to the Warrant Agent
    at its corporate trust office for exchange or registration of transfer, properly endorsed or accompanied by appropriate instruments
    of registration of transfer and written instructions for transfer, all in form satisfactory to the Company and the Warrant Agent.
    No service charge shall be made for any exchange or registration of transfer of Warrant Certificates, but the Company may require
    payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in connection with
    any such exchange or registration of transfer. Whenever any Warrant Certificates are so surrendered for exchange or registration
    of transfer, an authorized officer of the Warrant Agent shall manually countersign and deliver to the person or persons entitled
    thereto a Warrant Certificate or Warrant Certificates duly authorized and executed by the Company, as so requested. The Warrant
    Agent shall not be required to effect any exchange or registration of transfer which will result in the issuance of a Warrant Certificate
    evidencing a Warrant for a fraction of a Warrant Security or a number of Warrants for a whole number of Warrant Securities and
    a fraction of a Warrant Security. All Warrant Certificates issued upon any exchange or registration of transfer of Warrant Certificates
    shall be the valid obligations of the Company, evidencing the same obligations and entitled to the same benefits under this Agreement
    as the Warrant Certificate surrendered for such exchange or registration of transfer.

   

  4.2          Treatment of Holders of Warrant Certificates. The Company,
    the Warrant Agent and all other persons may treat the registered
    holder of a Warrant Certificate as the absolute owner thereof for any purpose and as the person entitled to exercise the rights
    represented by the Warrants evidenced thereby, any notice to the contrary notwithstanding.

   

  4.3          Cancellation of Warrant Certificates. Any Warrant Certificate
    surrendered for exchange, registration of transfer or
    exercise of the Warrants evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant Agent and all Warrant
    Certificates surrendered or so delivered to the Warrant Agent shall be promptly canceled by the Warrant Agent and shall not be
    reissued and, except as expressly permitted by this Agreement, no Warrant Certificate shall be issued hereunder in exchange therefor
    or in lieu thereof. The Warrant Agent shall deliver to the Company from time to time or otherwise dispose of canceled Warrant Certificates
    in a manner satisfactory to the Company.

    CONCERNING THE WARRANT AGENT

   

  5.1          Warrant Agent. The Company hereby appoints [●] as Warrant
    Agent of the Company in respect of the Warrants and
    the Warrant Certificates upon the terms and subject to the conditions herein set forth, and [●] hereby accepts such appointment.
    The Warrant Agent shall have the powers and authority granted to and conferred upon it in the Warrant Certificates and hereby and
    such further powers and authority to act on behalf of the Company as the Company may hereafter grant to or confer upon it. All
    of the terms and provisions with respect to such powers and authority contained in the Warrant Certificates are subject to and
    governed by the terms and provisions hereof.

   

  5.2          Conditions of Warrant Agent’s Obligations. The Warrant Agent
    accepts its obligations herein set forth upon the
    terms and conditions hereof, including the following to all of which the Company agrees and to all of which the rights hereunder
    of the holders from time to time of the Warrant Certificates shall be subject:

   

  (a)           Compensation and Indemnification. The Company agrees promptly
    to pay the Warrant Agent the compensation to be agreed
    upon with the Company for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket
    expenses (including reasonable counsel fees) incurred without negligence, bad faith or willful misconduct by the Warrant Agent
    in connection with the services rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent
    for, and to hold it harmless against, any loss, liability or expense incurred without negligence, bad faith or willful misconduct
    on the part of the Warrant Agent, arising out of or in connection with its acting as Warrant Agent hereunder, including the reasonable
    costs and expenses of defending against any claim of such liability.

   

  (b)           Agent for the Company. In acting under this Agreement and in
    connection with the Warrant Certificates, the Warrant Agent
    is acting solely as agent of the Company and does not assume any obligations or relationship of agency or trust for or with any
    of the holders of Warrant Certificates or beneficial owners of Warrants.

   

  (c)           Counsel. The Warrant Agent may consult with counsel
    satisfactory to it, which may include counsel for the Company, and
    the written advice of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered
    or omitted by it hereunder in good faith and in accordance with the advice of such counsel.

   

  (d)           Documents. The Warrant Agent shall be protected and shall
    incur no liability for or in respect of any action taken or
    omitted by it in reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other
    paper or document reasonably believed by it to be genuine and to have been presented or signed by the proper parties.

   

  (e)           Certain Transactions. The Warrant Agent, and its officers,
    directors and employees, may become the owner of, or acquire
    any interest in, Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to
    the extent permitted by applicable law, it or they may engage or be interested in any financial or other transaction with the Company
    and may act on, or as depositary, trustee or agent for, any committee or body of holders of Warrant Securities or other obligations
    of the Company as freely as if it were not the Warrant Agent hereunder. Nothing in this Agreement shall be deemed to prevent the
    Warrant Agent from acting as trustee under any indenture to which the Company is a party.

   

  
    9

    
      

    

  

   

  (f)            No Liability for Interest. Unless otherwise agreed with the
    Company, the Warrant Agent shall have no liability for interest
    on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates.

   

  (g)           No Liability for Invalidity. The Warrant Agent shall have no
    liability with respect to any invalidity of this Agreement
    or any of the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon).

   

  (h)           No Responsibility for Representations. The Warrant Agent shall
    not be responsible for any of the recitals or representations
    herein or in the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon), all of which are made
    solely by the Company.

   

  (i)            No Implied Obligations. The Warrant Agent shall be obligated
    to perform only such duties as are herein and in the Warrant
    Certificates specifically set forth and no implied duties or obligations shall be read into this Agreement or the Warrant Certificates
    against the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action hereunder which may tend to involve
    it in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured to it.
    The Warrant Agent shall not be accountable or under any duty or responsibility for the use by the Company of any of the Warrant
    Certificates authenticated by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or for the application
    by the Company of the proceeds of the Warrant Certificates. The Warrant Agent shall have no duty or responsibility in case of any
    default by the Company in the performance of its covenants or agreements contained herein or in the Warrant Certificates or in
    the case of the receipt of any written demand from a holder of a Warrant Certificate with respect to such default, including, without
    limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law
    or otherwise or, except as provided in Section 6.2 hereof, to make any demand upon the Company.

   

  5.3          Resignation, Removal and Appointment of Successors.

   

  (a)           The Company agrees, for the benefit of the holders from time to
    time of the Warrant Certificates, that there shall at
    all times be a Warrant Agent hereunder until all the Warrants have been exercised or are no longer exercisable.

   

  (b)           The Warrant Agent may at any time resign as agent by giving
    written notice to the Company of such intention on its part,
    specifying the date on which its desired resignation shall become effective; provided that such date shall not be less than three
    months after the date on which such notice is given unless the Company otherwise agrees. The Warrant Agent hereunder may be removed
    at any time by the filing with it of an instrument in writing signed by or on behalf of the Company and specifying such removal
    and the intended date when it shall become effective. Such resignation or removal shall take effect upon the appointment by the
    Company, as hereinafter provided, of a successor Warrant Agent (which shall be a bank or trust company authorized under the laws
    of the jurisdiction of its organization to exercise corporate trust powers) and the acceptance of such appointment by such successor
    Warrant Agent. The obligation of the Company under Section 5.2(a) shall continue to the extent set forth therein notwithstanding
    the resignation or removal of the Warrant Agent.

   

  (c)           In case at any time the Warrant Agent shall resign, or shall be
    removed, or shall become incapable of acting, or shall
    be adjudged a bankrupt or insolvent, or shall commence a voluntary case under the Federal bankruptcy laws, as now or hereafter
    constituted, or under any other applicable Federal or state bankruptcy, insolvency or similar law or shall consent to the appointment
    of or taking possession by a receiver, custodian, liquidator, assignee, trustee, sequestrator (or other similar official) of the
    Warrant Agent or its property or affairs, or shall make an assignment for the benefit of creditors, or shall admit in writing its
    inability to pay its debts generally as they become due, or shall take corporate action in furtherance of any such action, or a
    decree or order for relief by a court having jurisdiction in the premises shall have been entered in respect of the Warrant Agent
    in an involuntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or state
    bankruptcy, insolvency or similar law, or a decree or order by a court having jurisdiction in the premises shall have been entered
    for the appointment of a receiver, custodian, liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant
    Agent or of its property or affairs, or any public officer shall take charge or control of the Warrant Agent or of its property
    or affairs for the purpose of rehabilitation, conservation, winding up or liquidation, a successor Warrant Agent, qualified as
    aforesaid, shall be appointed by the Company by an instrument in writing, filed with the successor Warrant Agent. Upon the appointment
    as aforesaid of a successor Warrant Agent and acceptance by the successor Warrant Agent of such appointment, the Warrant Agent
    shall cease to be Warrant Agent hereunder.

   

  
    10

    
      

    

  

   

  (d)           Any
    successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its predecessor and to the Company an instrument
    accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act, deed or conveyance,
    shall become vested with all the authority, rights, powers, trusts, immunities, duties and obligations of such predecessor with
    like effect as if originally named as Warrant Agent hereunder, and such predecessor, upon payment of its charges and disbursements
    then unpaid, shall thereupon become obligated to transfer, deliver and pay over, and such successor Warrant Agent shall be entitled
    to receive, all monies, securities and other property on deposit with or held by such predecessor, as Warrant Agent hereunder.

   

  (e)           Any corporation into which the Warrant Agent hereunder may be
    merged or converted or any corporation with which the
    Warrant Agent may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant
    Agent shall be a party, or any corporation to which the Warrant Agent shall sell or otherwise transfer all or substantially all
    the assets and business of the Warrant Agent, provided that it shall be qualified as aforesaid, shall be the successor Warrant
    Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto.

      the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing so to act, in
    connection with the issuance, registration, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this
    Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the terms and conditions
    on which they may be issued, registered, transferred, exchanged, exercised and replaced.

   

  Now
        Therefore, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree
    as follows:

   

  Article
    1

    

    ISSUANCE OF WARRANTS AND EXECUTION AND

    DELIVERY OF WARRANT CERTIFICATES

   

  1.1          Issuance of Warrants. [If Warrants alone —Upon
    issuance, each Warrant Certificate shall evidence
    one or more Warrants.] [If Other Securities and Warrants —Warrant Certificates will be issued in connection
    with the issuance of the Other Securities but shall be separately transferable and each Warrant Certificate shall evidence one
    or more Warrants.] Each Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein,
    to purchase one Warrant Security. [If Other Securities and Warrants —Warrant Certificates will be issued with
    the Other Securities and each Warrant Certificate will evidence [●] Warrants for each [$[●] principal amount] [[●]
    shares] of Other Securities issued.]

   

  1.2          Execution and Delivery of Warrant Certificates. Each Warrant
    Certificate, whenever issued, shall be in registered form
    substantially in the form set forth in Exhibit A hereto, shall be dated the date of its countersignature by the Warrant
    Agent and may have such letters, numbers, or other marks of identification or designation and such legends or endorsements printed,
    lithographed or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive
    evidence of such approval) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with
    any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange on which
    the Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf of the Company by any of
    its present or future chief executive officers, presidents, senior vice presidents, vice presidents, chief financial officers,
    chief legal officers, treasurers, assistant treasurers, controllers, assistant controllers, secretaries or assistant secretaries
    under its corporate seal reproduced thereon. Such signatures may be manual or facsimile signatures of such authorized officers
    and may be imprinted or otherwise reproduced on the Warrant Certificates. The seal of the Company may be in the form of a facsimile
    thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Warrant Certificates.

   

  
    1

    
      

    

  

   

  No Warrant Certificate
    shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant Certificate has been
    countersigned by the manual signature of the Warrant Agent. Such signature by the Warrant Agent upon any Warrant Certificate executed
    by the Company shall be conclusive evidence that the Warrant Certificate so countersigned has been duly issued hereunder.

   

  In case any officer
    of the Company who shall have signed any of the Warrant Certificates either manually or by facsimile signature shall cease to be
    such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent, such Warrant
    Certificates may be countersigned and delivered notwithstanding that the person who signed such Warrant Certificates ceased to
    be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual
    date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution
    of this Agreement any such person was not such officer.

   

  The term “holder”
    or “holder of a Warrant Certificate” as used herein shall mean any person in whose name at the time any
    Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose.

   

  1.3         Issuance of Warrant Certificates. Warrant Certificates
    evidencing the right to purchase Warrant Securities may be executed
    by the Company and delivered to the Warrant Agent upon the execution of this Agreement or from time to time thereafter. The Warrant
    Agent shall, upon receipt of Warrant Certificates duly executed on behalf of the Company, countersign such Warrant Certificates
    and shall deliver such Warrant Certificates to or upon the order of the Company.

    WARRANT PRICE, DURATION AND EXERCISE OF WARRANTS

   

  2.1         Warrant Price. During the period specified in Section 2.2,
    each Warrant shall, subject to the terms of this Agreement
    and the applicable Warrant Certificate, entitle the holder thereof to purchase the number of Warrant Securities specified in the
    applicable Warrant Certificate at an exercise price of $[●] per Warrant Security, subject to adjustment upon the occurrence
    of certain events, as hereinafter provided. Such purchase price per Warrant Security is referred to in this Agreement as the “Warrant
        Price.”

   

  2.2         Duration of Warrants. Each Warrant may be exercised in whole
    or in part at any time, as specified herein, on or after
    [the date thereof] [●] and at or before [●] p.m., [City] time, on [●] or such later date as the Company may designate
    by notice to the Warrant Agent and the holders of Warrant Certificates mailed to their addresses as set forth in the record books
    of the Warrant Agent (the “Expiration Date”). Each Warrant not exercised at or before [●] p.m.,
    [City] time, on the Expiration Date shall become void, and all rights of the holder of the Warrant Certificate evidencing such
    Warrant under this Agreement shall cease.

  2.3         Exercise of Warrants.

   

  (a)          During the period specified in Section 2.2, the Warrants may be
    exercised to purchase a whole number of Warrant Securities
    in registered form by providing certain information as set forth on the reverse side of the Warrant Certificate and by paying in
    full, in lawful money of the United States of America, [in cash or by certified check or official bank check in New York Clearing
    House funds] [by bank wire transfer in immediately available funds] the Warrant Price for each Warrant Security with respect to
    which a Warrant is being exercised to the Warrant Agent at its corporate trust office, provided that such exercise is subject to
    receipt within five business days of such payment by the Warrant Agent of the Warrant Certificate with the form of election to
    purchase Warrant Securities set forth on the reverse side of the Warrant Certificate properly completed and duly executed. The
    date on which payment in full of the Warrant Price is received by the Warrant Agent shall, subject to receipt of the Warrant Certificate
    as aforesaid, be deemed to be the date on which the Warrant is exercised; provided, however, that if, at the date of receipt of
    such Warrant Certificates and payment in full of the Warrant Price, the transfer books for the Warrant Securities purchasable upon
    the exercise of such Warrants shall be closed, no such receipt of such Warrant Certificates and no such payment of such Warrant
    Price shall be effective to constitute the person so designated to be named as the holder of record of such Warrant Securities
    on such date, but shall be effective to constitute such person as the holder of record of such Warrant Securities for all purposes
    at the opening of business on the next succeeding day on which the transfer books for the Warrant Securities purchasable upon the
    exercise of such Warrants shall be opened, and the certificates for the Warrant Securities in respect of which such Warrants are
    then exercised shall be issuable as of the date on such next succeeding day on which the transfer books shall next be opened, and
    until such date the Company shall be under no duty to deliver any certificate for such Warrant Securities. The Warrant Agent shall
    deposit all funds received by it in payment of the Warrant Price in an account of the Company maintained with it and shall advise
    the Company by telephone at the end of each day on which a payment for the exercise of Warrants is received of the amount so deposited
    to its account. The Warrant Agent shall promptly confirm such telephone advice to the Company in writing.

   

  (b)          The Warrant Agent shall, from time to time, as promptly as
    practicable, advise the Company of (i) the number of Warrant
    Securities with respect to which Warrants were exercised, (ii) the instructions of each holder of the Warrant Certificates evidencing
    such Warrants with respect to delivery of the Warrant Securities to which such holder is entitled upon such exercise, (iii) delivery
    of Warrant Certificates evidencing the balance, if any, of the Warrants for the remaining Warrant Securities after such exercise,
    and (iv) such other information as the Company shall reasonably require.

   

  (c)          As soon as practicable after the exercise of any Warrant, the
    Company shall issue to or upon the order of the holder
    of the Warrant Certificate evidencing such Warrant the Warrant Securities to which such holder is entitled, in fully registered
    form, registered in such name or names as may be directed by such holder. If fewer than all of the Warrants evidenced by such Warrant
    Certificate are exercised, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign
    and deliver, a new Warrant Certificate evidencing Warrants for the number of Warrant Securities remaining unexercised.

   

  (d)          The Company shall not be required to pay any stamp or other tax
    or other governmental charge required to be paid in
    connection with any transfer involved in the issue of the Warrant Securities, and in the event that any such transfer is involved,
    the Company shall not be required to issue or deliver any Warrant Security until such tax or other charge shall have been paid
    or it has been established to the Company’s satisfaction that no such tax or other charge is due.

   

  (e)          Prior to the issuance of any Warrants there shall have been
    reserved, and the Company shall at all times through the
    Expiration Date keep reserved, out of its authorized but unissued Warrant Securities, a number of shares sufficient to provide
    for the exercise of the Warrants.

    OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF

    WARRANT CERTIFICATES

   

  3.1          No Rights as Warrant Securityholder Conferred by Warrants or
      Warrant Certificates. No Warrant Certificate or Warrant
    evidenced thereby shall entitle the holder thereof to any of the rights of a holder of Warrant Securities, including, without limitation,
    the right to receive the payment of dividends or distributions, if any, on the Warrant Securities or to exercise any voting rights,
    except to the extent expressly set forth in this Agreement or the applicable Warrant Certificate.

   

  3.2          Lost, Stolen, Mutilated or Destroyed Warrant Certificates. Upon
    receipt by the Warrant Agent of evidence reasonably
    satisfactory to it and the Company of the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate
    and/or indemnity reasonably satisfactory to the Warrant Agent and the Company and, in the case of mutilation, upon surrender of
    the mutilated Warrant Certificate to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant
    Agent that such Warrant Certificate has been acquired by a bona fide purchaser, the Company shall execute, and an authorized officer
    of the Warrant Agent shall manually countersign and deliver, in exchange for or in lieu of the lost, stolen, destroyed or mutilated
    Warrant Certificate, a new Warrant Certificate of the same tenor and evidencing Warrants for a like number of Warrant Securities.
    Upon the issuance of any new Warrant Certificate under this Section 3.2, the Company may require the payment of a sum sufficient
    to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees
    and expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant
    to this Section 3.2 in lieu of any lost, stolen or destroyed Warrant Certificate shall represent an additional contractual obligation
    of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and
    shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly
    executed and delivered hereunder. The provisions of this Section 3.2 are exclusive and shall preclude (to the extent lawful) all
    other rights and remedies with respect to the replacement of mutilated, lost, stolen or destroyed Warrant Certificates.

   

  3.3          Holder of Warrant Certificate May Enforce Rights. Notwithstanding
    any of the provisions of this Agreement, any holder
    of a Warrant Certificate, without the consent of the Warrant Agent, the holder of any Warrant Securities or the holder of any other
    Warrant Certificate, may, in such holder’s own behalf and for such holder’s own benefit, enforce, and may institute
    and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such holder’s
    right to exercise the Warrants evidenced by such holder’s Warrant Certificate in the manner provided in such holder’s
    Warrant Certificate and in this Agreement.

   

  3.4          Adjustments.

   

  (a)          In case the Company shall at any time subdivide its outstanding
    shares of [title of Preferred Stock purchasable through
    exercise of Warrants] into a greater number of shares, the Warrant Price in effect immediately prior to such subdivision shall
    be proportionately reduced and the number of Warrant Securities purchasable under the Warrants shall be proportionately increased.
    Conversely, in case the outstanding shares of [title of Preferred Stock purchasable through exercise of Warrants] shall be combined
    into a smaller number of shares, the Warrant Price in effect immediately prior to such combination shall be proportionately increased
    and the number of Warrant Securities purchasable under the Warrants shall be proportionately decreased.

   

  
    4

    
      

    

  

   

  (b)          If at any time or from time to time the holders of [title of
    Preferred Stock purchasable through exercise of Warrants]
    (or any shares of stock or other securities at the time receivable upon the exercise of the Warrants) shall have received or become
    entitled to receive, without payment therefore,

   

  (i)          [title of Preferred Stock purchasable through exercise of
    Warrants] or any shares of stock or other securities which
    are at any time directly or indirectly convertible into or exchangeable for [title of Preferred Stock purchasable through exercise
    of Warrants], or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend
    or other distribution;

   

  (ii)         any cash paid or payable otherwise than in accordance with the
    terms of [title of Preferred Stock purchasable through
    exercise of Warrants] or as a cash dividend paid or payable out of the Company’s current or retained earnings;

   

  (iii)        any evidence of the Company’s indebtedness or rights to
    subscribe for or purchase the Company’s indebtedness;
    or

   

  (iv)         [title of Preferred Stock purchasable through exercise of
    Warrants] or additional stock or other securities or property
    (including cash) by way of spinoff, split-up, reclassification, combination of shares or similar corporate rearrangement (other
    than shares of [title of Preferred Stock purchasable through exercise of Warrants] issued as a stock split or adjustments in respect
    of which shall be covered by the terms of Section 3.4(a) above), then and in each such case, the holder of each Warrant shall,
    upon the exercise of the Warrant, be entitled to receive, in addition to the number of Warrant Securities receivable thereupon,
    and without payment of any additional consideration therefore, the amount of stock and other securities and property (including
    cash and indebtedness or rights to subscribe for or purchase indebtedness) which such holder would hold on the date of such exercise
    had such holder been the holder of record of such Warrant Securities as of the date on which holders of [title of Preferred Stock
    purchasable through exercise of Warrants] received or became entitled to receive such shares or all other additional stock and
    other securities and property.

   

  (c)          In case of (i) any reclassification, capital reorganization, or
    change in the [title of Preferred Stock purchasable
    through exercise of Warrants] of the Company (other than as a result of a subdivision, combination, or stock dividend provided
    for in Section 3.4(a) or Section 3.4(b) above), (ii) share exchange, merger or similar transaction of the Company with or
    into another person or entity (other than a share exchange, merger or similar transaction in which the Company is the acquiring
    or surviving corporation and which does not result in any change in the [title of Preferred Stock purchasable through exercise
    of Warrants] other than the issuance of additional shares of [title of Preferred Stock purchasable through exercise of Warrants])
    or (iii) the sale, exchange, lease, transfer or other disposition of all or substantially all of the properties and assets of the
    Company as an entirety (in any such case, a “Reorganization Event”), then, as a condition of such Reorganization
    Event, lawful provisions shall be made, and duly executed documents evidencing the same from the Company or its successor shall
    be delivered to the holders of the Warrants, so that the holders of the Warrants shall have the right at any time prior to the
    expiration of the Warrants to purchase, at a total price equal to that payable upon the exercise of the Warrants, the kind and
    amount of shares of stock and other securities and property receivable in connection with such Reorganization Event by a holder
    of the same number of shares of [title of Preferred Stock purchasable through exercise of Warrants] as were purchasable by the
    holders of the Warrants immediately prior to such Reorganization Event. In any such case appropriate provisions shall be made with
    respect to the rights and interests of the holders of the Warrants so that the provisions hereof shall thereafter be applicable
    with respect to any shares of stock or other securities and property deliverable upon exercise the Warrants, and appropriate adjustments
    shall be made to the Warrant Price payable hereunder provided the aggregate purchase price shall remain the same. In the case of
    any transaction described in clauses (ii) and (iii) above, the Company shall thereupon be relieved of any further obligation hereunder
    or under the Warrants, and the Company as the predecessor corporation may thereupon or at any time thereafter be dissolved, wound
    up or liquidated. Such successor or assuming entity thereupon may cause to be signed, and may issue either in its own name or in
    the name of the Company, any or all of the Warrants issuable hereunder which heretofore shall not have been signed by the Company,
    and may execute and deliver securities in its own name, in fulfillment of its obligations to deliver Warrant Securities upon exercise
    of the Warrants. All the Warrants so issued shall in all respects have the same legal rank and benefit under this Agreement as
    the Warrants theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Warrants had
    been issued at the date of the execution hereof. In any case of any such Reorganization Event, such changes in phraseology and
    form (but not in substance) may be made in the Warrants thereafter to be issued as may be appropriate. The Warrant Agent may receive
    a written opinion of legal counsel as conclusive evidence that any such Reorganization Event complies with the provisions of this
    Section 3.4.

   

  
    5

    
      

    

  

   

  (d)          The Company may, at its option, at any time until the Expiration
    Date, reduce the then current Warrant Price to any
    amount deemed appropriate by the Board of Directors of the Company for any period not exceeding twenty consecutive days (as evidenced
    in a resolution adopted by such Board of Directors), but only upon giving the notices required by Section 3.5 at least ten days
    prior to taking such action.

   

  (e)          Except as herein otherwise expressly provided, no adjustment in
    the Warrant Price shall be made by reason of the issuance
    of any securities of the Company or for any other reason whatsoever.

   

  (f)           No fractional Warrant Securities shall be issued upon the
    exercise of Warrants. If more than one Warrant shall be exercised
    at one time by the same holder, the number of full Warrant Securities which shall be issuable upon such exercise shall be computed
    on the basis of the aggregate number of Warrant Securities purchased pursuant to the Warrants so exercised. Instead of any fractional
    Warrant Security which would otherwise be issuable upon exercise of any Warrant, the Company shall pay a cash adjustment in respect
    of such fraction in an amount equal to the same fraction of the last reported sale price (or bid price if there were no sales)
    per Warrant Security, in either case as reported on the principal registered national securities exchange on which the Warrant
    Securities are listed or admitted to trading on the business day that next precedes the day of exercise or, if the Warrant Securities
    are not then listed or admitted to trading on any registered national securities exchange, the average of the closing high bid
    and low asked prices as reported on the OTC Bulletin Board Service (the “OTC Bulletin Board”) operated
    by the Financial Industry Regulatory Authority, Inc. (“FINRA” ) or, if not available on the OTC Bulletin
    Board, then the average of the closing high bid and low asked prices as reported on any other U.S. quotation medium or inter-dealer
    quotation system on such date, or if on any such date the Warrant Securities are not listed or admitted to trading on a registered
    national securities exchange, are not included in the OTC Bulletin Board, and are not quoted on any other U.S. quotation medium
    or inter-dealer quotation system, an amount equal to the same fraction of the average of the closing bid and asked prices as furnished
    by any FINRA member firm selected from time to time by the Company for that purpose at the close of business on the business day
    that next precedes the day of exercise.

   

  (g)          Whenever the Warrant Price then in effect is adjusted as herein
    provided, the Company shall mail to each holder of the
    Warrants at such holder’s address as it shall appear on the books of the Company a statement setting forth the adjusted Warrant
    Price then and thereafter effective under the provisions hereof, together with the facts, in reasonable detail, upon which such
    adjustment is based.

   

  
    6

    
      

    

  

   

  (h)          Notwithstanding anything to the
      contrary herein, in no event shall the Warrant Price, as adjusted in accordance with
      the terms hereof, be less than the par value per share of [title of Preferred Stock purchasable through exercise of Warrants].

   

  3.5         Notice to Warrantholders. In
      case the Company shall (a) effect any dividend or distribution described in Section 3.4(b),
      (b) effect any Reorganization Event, (c) make any distribution on or in respect of the [title of Preferred Stock purchasable
    through exercise of Warrants] in connection with the dissolution, liquidation or winding up of the
      Company, or (d) reduce the then current Warrant Price pursuant to Section 3.4(d), then the Company shall mail to each holder of
      Warrants at such holder’s address as it shall appear on the books of the Warrant Agent, at least ten days prior to the applicable
      date hereinafter specified, a notice stating (x) the record date for such dividend or distribution, or, if a record is not to be
      taken, the date as of which the holders of record of [title of Preferred Stock purchasable through exercise of Warrants]
    that will be entitled to such dividend or distribution are to be determined, (y) the date on which
      such Reorganization Event, dissolution, liquidation or winding up is expected to become effective, and the date as of which it
      is expected that holders of [title of Preferred Stock purchasable through exercise of Warrants] of
      record shall be entitled to exchange their shares of [title of Preferred Stock purchasable through exercise of Warrants]
    for securities or other property deliverable upon such Reorganization Event, dissolution, liquidation
      or winding up, or (z) the first date on which the then current Warrant Price shall be reduced pursuant to Section 3.4(d). No failure
      to mail such notice nor any defect therein or in the mailing thereof shall affect any such transaction or any adjustment in the
      Warrant Price required by Section 3.4.

   

  3.6         [If the Warrants are Subject to Acceleration by the Company,
    Insert — Acceleration of Warrants by the Company.

   

  (a)          At any time on or after [●], the
      Company shall have the right to accelerate any or all Warrants at any time by
      causing them to expire at the close of business on the day next preceding a specified date (the “Acceleration Date”),
      if the Market Price (as hereinafter defined) of the [title of Preferred Stock purchasable through exercise of Warrants]
    equals or exceeds [●] percent ([●]%) of the then effective Warrant Price on any twenty
      Trading Days (as hereinafter defined) within a period of thirty consecutive Trading Days ending no more than five Trading Days
      prior to the date on which the Company gives notice to the Warrant Agent of its election to accelerate the Warrants.

   

  (b)          (b) “Market Price”
      for each Trading Day shall be, if the [title of Preferred Stock
    purchasable through exercise of Warrants] is listed or admitted to trading on any registered national
      securities exchange, the last reported sale price, regular way (or, if no such price is reported, the average of the reported closing
      bid and asked prices, regular way) of [title of Preferred Stock purchasable through exercise of Warrants],
      in either case as reported on the principal registered national securities exchange on which the [title of Preferred Stock
    purchasable through exercise of Warrants] is listed or admitted to trading or, if not listed or admitted
      to trading on any registered national securities exchange, the average of the closing high bid and low asked prices as reported
      on the OTC Bulletin Board operated by FINRA, or if not available on the OTC Bulletin Board, then the average of the closing high
      bid and low asked prices as reported on any other U.S. quotation medium or inter-dealer quotation system, or if on any such date
      the shares of [title of Preferred Stock purchasable through exercise of Warrants] are not
      listed or admitted to trading on a registered national securities exchange, are not included in the OTC Bulletin Board, and are
      not quoted on any other U.S. quotation medium or inter-dealer quotation system, the average of the closing bid and asked prices
      as furnished by any FINRA member firm selected from time to time by the Company for that purpose. “Trading Day” shall
      be each Monday through Friday, other than any day on which securities are not traded in the system or on the exchange that is the
      principal market for the [title of Preferred Stock purchasable through exercise of Warrants],
      as determined by the Board of Directors of the Company. In the event of an acceleration of less than all of the Warrants, the Warrant
      Agent shall select the Warrants to be accelerated by lot, pro rata or in such other manner as it deems, in its discretion, to be
      fair and appropriate.

   

  
    7

    
      

    

  

   

  (c)          Notice of an acceleration specifying the Acceleration Date shall
    be sent by mail first class, postage prepaid, to each
    registered holder of a Warrant Certificate representing a Warrant accelerated at such holder’s address appearing on the books
    of the Warrant Agent not more than sixty days nor less than thirty days before the Acceleration Date. Such notice of an acceleration
    also shall be given no more than twenty days, and no less than ten days, prior to the mailing of notice to registered holders of
    Warrants pursuant to this Section 3.6, by publication at least once in a newspaper of general circulation in the City of New York.

   

  (d)          Any Warrant accelerated may be exercised until [●] p.m., [City]
    time, on the business day next preceding the Acceleration
    Date. The Warrant Price shall be payable as provided in Section 2.]

    EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES

   

  4.1         Exchange and Transfer of Warrant Certificates. Upon surrender
    at the corporate trust office of the Warrant Agent, Warrant
    Certificates evidencing Warrants may be exchanged for Warrant Certificates in other denominations evidencing such Warrants or the
    transfer thereof may be registered in whole or in part; provided that such other Warrant Certificates evidence Warrants for the
    same aggregate number of Warrant Securities as the Warrant Certificates so surrendered. The Warrant Agent shall keep, at its corporate
    trust office, books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates
    and exchanges and transfers of outstanding Warrant Certificates, upon surrender of the Warrant Certificates to the Warrant Agent
    at its corporate trust office for exchange or registration of transfer, properly endorsed or accompanied by appropriate instruments
    of registration of transfer and written instructions for transfer, all in form satisfactory to the Company and the Warrant Agent.
    No service charge shall be made for any exchange or registration of transfer of Warrant Certificates, but the Company may require
    payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in connection with
    any such exchange or registration of transfer. Whenever any Warrant Certificates are so surrendered for exchange or registration
    of transfer, an authorized officer of the Warrant Agent shall manually countersign and deliver to the person or persons entitled
    thereto a Warrant Certificate or Warrant Certificates duly authorized and executed by the Company, as so requested. The Warrant
    Agent shall not be required to effect any exchange or registration of transfer which will result in the issuance of a Warrant Certificate
    evidencing a Warrant for a fraction of a Warrant Security or a number of Warrants for a whole number of Warrant Securities and
    a fraction of a Warrant Security. All Warrant Certificates issued upon any exchange or registration of transfer of Warrant Certificates
    shall be the valid obligations of the Company, evidencing the same obligations and entitled to the same benefits under this Agreement
    as the Warrant Certificate surrendered for such exchange or registration of transfer.

   

  4.2         Treatment of Holders of Warrant Certificates. The Company, the
    Warrant Agent and all other persons may treat the registered
    holder of a Warrant Certificate as the absolute owner thereof for any purpose and as the person entitled to exercise the rights
    represented by the Warrants evidenced thereby, any notice to the contrary notwithstanding.

   

  4.3         Cancellation of Warrant Certificates. Any Warrant Certificate
    surrendered for exchange, registration of transfer or
    exercise of the Warrants evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant Agent and all Warrant
    Certificates surrendered or so delivered to the Warrant Agent shall be promptly canceled by the Warrant Agent and shall not be
    reissued and, except as expressly permitted by this Agreement, no Warrant Certificate shall be issued hereunder in exchange therefor
    or in lieu thereof. The Warrant Agent shall deliver to the Company from time to time or otherwise dispose of canceled Warrant Certificates
    in a manner satisfactory to the Company.

    CONCERNING THE WARRANT AGENT

   

  5.1          Warrant Agent. The Company hereby appoints [●] as Warrant
    Agent of the Company in respect of the Warrants and
    the Warrant Certificates upon the terms and subject to the conditions herein set forth, and [●] hereby accepts such appointment.
    The Warrant Agent shall have the powers and authority granted to and conferred upon it in the Warrant Certificates and hereby and
    such further powers and authority to act on behalf of the Company as the Company may hereafter grant to or confer upon it. All
    of the terms and provisions with respect to such powers and authority contained in the Warrant Certificates are subject to and
    governed by the terms and provisions hereof.

   

  5.2          Conditions of Warrant Agent’s Obligations. The Warrant Agent
    accepts its obligations herein set forth upon the
    terms and conditions hereof, including the following to all of which the Company agrees and to all of which the rights hereunder
    of the holders from time to time of the Warrant Certificates shall be subject:

   

  (a)          Compensation and Indemnification. The Company agrees promptly
    to pay the Warrant Agent the compensation to be agreed
    upon with the Company for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket
    expenses (including reasonable counsel fees) incurred without negligence, bad faith or willful misconduct by the Warrant Agent
    in connection with the services rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent
    for, and to hold it harmless against, any loss, liability or expense incurred without negligence, bad faith or willful misconduct
    on the part of the Warrant Agent, arising out of or in connection with its acting as Warrant Agent hereunder, including the reasonable
    costs and expenses of defending against any claim of such liability.

   

  (b)          Agent for the Company. In acting under this Agreement and in
    connection with the Warrant Certificates, the Warrant Agent
    is acting solely as agent of the Company and does not assume any obligations or relationship of agency or trust for or with any
    of the holders of Warrant Certificates or beneficial owners of Warrants.

   

  (c)          Counsel. The Warrant Agent may consult with counsel
    satisfactory to it, which may include counsel for the Company, and
    the written advice of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered
    or omitted by it hereunder in good faith and in accordance with the advice of such counsel.

   

  (d)          Documents. The Warrant Agent shall be protected and shall incur
    no liability for or in respect of any action taken or
    omitted by it in reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other
    paper or document reasonably believed by it to be genuine and to have been presented or signed by the proper parties.

   

  (e)          Certain Transactions. The Warrant Agent, and its officers,
    directors and employees, may become the owner of, or acquire
    any interest in, Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to
    the extent permitted by applicable law, it or they may engage or be interested in any financial or other transaction with the Company
    and may act on, or as depositary, trustee or agent for, any committee or body of holders of Warrant Securities or other obligations
    of the Company as freely as if it were not the Warrant Agent hereunder. Nothing in this Agreement shall be deemed to prevent the
    Warrant Agent from acting as trustee under any indenture to which the Company is a party.

   

  
    9

    
      

    

  

   

  (f)           No Liability for Interest. Unless otherwise agreed with the
    Company, the Warrant Agent shall have no liability for interest
    on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates.

   

  (g)          No Liability for Invalidity. The Warrant Agent shall have no
    liability with respect to any invalidity of this Agreement
    or any of the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon).

   

  (h)          No Responsibility for Representations. The Warrant Agent shall
    not be responsible for any of the recitals or representations
    herein or in the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon), all of which are made
    solely by the Company.

   

  (i)           No Implied Obligations. The Warrant Agent shall be obligated
    to perform only such duties as are herein and in the Warrant
    Certificates specifically set forth and no implied duties or obligations shall be read into this Agreement or the Warrant Certificates
    against the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action hereunder which may tend to involve
    it in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured to it.
    The Warrant Agent shall not be accountable or under any duty or responsibility for the use by the Company of any of the Warrant
    Certificates authenticated by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or for the application
    by the Company of the proceeds of the Warrant Certificates. The Warrant Agent shall have no duty or responsibility in case of any
    default by the Company in the performance of its covenants or agreements contained herein or in the Warrant Certificates or in
    the case of the receipt of any written demand from a holder of a Warrant Certificate with respect to such default, including, without
    limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law
    or otherwise or, except as provided in Section 6.2 hereof, to make any demand upon the Company.

   

  5.3         Resignation, Removal and Appointment of Successors.

   

  (a)          The Company agrees, for the benefit of the holders from time to
    time of the Warrant Certificates, that there shall at
    all times be a Warrant Agent hereunder until all the Warrants have been exercised or are no longer exercisable.

   

  (b)          The Warrant Agent may at any time resign as agent by giving
    written notice to the Company of such intention on its part,
    specifying the date on which its desired resignation shall become effective; provided that such date shall not be less than three
    months after the date on which such notice is given unless the Company otherwise agrees. The Warrant Agent hereunder may be removed
    at any time by the filing with it of an instrument in writing signed by or on behalf of the Company and specifying such removal
    and the intended date when it shall become effective. Such resignation or removal shall take effect upon the appointment by the
    Company, as hereinafter provided, of a successor Warrant Agent (which shall be a bank or trust company authorized under the laws
    of the jurisdiction of its organization to exercise corporate trust powers) and the acceptance of such appointment by such successor
    Warrant Agent. The obligation of the Company under Section 5.2(a) shall continue to the extent set forth therein notwithstanding
    the resignation or removal of the Warrant Agent.

   

  
    10

    
      

    

  

   

  (c)          In case at any time the Warrant Agent shall resign, or shall be
    removed, or shall become incapable of acting, or shall
    be adjudged a bankrupt or insolvent, or shall commence a voluntary case under the Federal bankruptcy laws, as now or hereafter
    constituted, or under any other applicable Federal or state bankruptcy, insolvency or similar law or shall consent to the appointment
    of or taking possession by a receiver, custodian, liquidator, assignee, trustee, sequestrator (or other similar official) of the
    Warrant Agent or its property or affairs, or shall make an assignment for the benefit of creditors, or shall admit in writing its
    inability to pay its debts generally as they become due, or shall take corporate action in furtherance of any such action, or a
    decree or order for relief by a court having jurisdiction in the premises shall have been entered in respect of the Warrant Agent
    in an involuntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or state
    bankruptcy, insolvency or similar law, or a decree or order by a court having jurisdiction in the premises shall have been entered
    for the appointment of a receiver, custodian, liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant
    Agent or of its property or affairs, or any public officer shall take charge or control of the Warrant Agent or of its property
    or affairs for the purpose of rehabilitation, conservation, winding up or liquidation, a successor Warrant Agent, qualified as
    aforesaid, shall be appointed by the Company by an instrument in writing, filed with the successor Warrant Agent. Upon the appointment
    as aforesaid of a successor Warrant Agent and acceptance by the successor Warrant Agent of such appointment, the Warrant Agent
    shall cease to be Warrant Agent hereunder.

   

  (d)          Any successor Warrant Agent appointed hereunder shall execute,
    acknowledge and deliver to its predecessor and to the
    Company an instrument accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act,
    deed or conveyance, shall become vested with all the authority, rights, powers, trusts, immunities, duties and obligations of such
    predecessor with like effect as if originally named as Warrant Agent hereunder, and such predecessor, upon payment of its charges
    and disbursements then unpaid, shall thereupon become obligated to transfer, deliver and pay over, and such successor Warrant Agent
    shall be entitled to receive, all monies, securities and other property on deposit with or held by such predecessor, as Warrant
    Agent hereunder.

   

  (e)          Any corporation into which the Warrant Agent hereunder may be
    merged or converted or any corporation with which the
    Warrant Agent may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant
    Agent shall be a party, or any corporation to which the Warrant Agent shall sell or otherwise transfer all or substantially all
    the assets and business of the Warrant Agent, provided that it shall be qualified as aforesaid, shall be the successor Warrant
    Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto.
