        record date” as used in this Section with respect to a series of Securities and any Interest Payment Date for such series shall mean either the fifteenth day of the month immediately preceding the month in which an Interest Payment Date established
        for such series pursuant to Section 2.01 hereof shall occur, if such Interest Payment Date is the first day of a month, or the first day of the month in which an Interest Payment Date established for such series pursuant to Section 2.01 hereof
        shall occur, if such Interest Payment Date is the fifteenth day of a month, whether or not such date is a Business Day.

      

      

      
        9

        
          

      

      Subject to the foregoing provisions of this Section, each Security of a series delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Security of such series
        shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Security.

      

      

      Section 2.04          Execution and Authentications.

      

      

      The Securities shall be signed on behalf of the Company by one of its Officers.  Signatures may be in the form of a manual or facsimile signature.

      

      

      The Company may use the facsimile signature of any Person who shall have been an Officer (at the time of execution), notwithstanding the fact that at the time the Securities shall be authenticated
        and delivered or disposed of such Person shall have ceased to be such an officer of the Company.  The Securities may contain such notations, legends or endorsements required by law, stock exchange rule or usage.  Each Security shall be dated the
        date of its authentication by the Trustee.

      

      

      A Security shall not be valid until authenticated manually by an authorized signatory of the Trustee, or by an Authenticating Agent.  Such signature shall be conclusive evidence that the Security
        so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture.  At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver
        Securities of any series executed by the Company to the Trustee for authentication, together with a written order of the Company for the authentication and delivery of such Securities, signed by an Officer, and the Trustee in accordance with such
        written order shall authenticate and deliver such Securities.

      

      

      Upon the Company’s delivery of any such authentication order to the Trustee at any time after the initial issuance of Securities under this Indenture, the Trustee shall be provided with, and
        (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon, (1) an Opinion of Counsel or reliance letter and (2) an Officer’s Certificate stating that all conditions precedent to the execution,
        authentication and delivery of such Securities are in conformity with the provisions of this Indenture.

      

      

      The Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the
        Securities and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee.

      

      

      Section 2.05          Registration of Transfer and Exchange.

      

      

      (a)          Securities of any series may be exchanged upon presentation thereof at the office or agency of the Company designated for such purpose, for
        other Securities of such series of authorized denominations, and for a like aggregate principal amount, upon payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, all as provided in this Section.  In respect
        of any Securities so surrendered for exchange, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in exchange therefor the Security or Securities of the same series that the Securityholder making the
        exchange shall be entitled to receive, bearing numbers not contemporaneously outstanding.

      

      

      
        10

        
          

      

      (b)          The Company shall keep, or cause to be kept, at its office or agency designated for such purpose a register or registers (herein referred to as
        the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall register the Securities and the transfers of Securities as in this Article provided and which at all reasonable times shall be open for
        inspection by the Trustee.  The registrar for the purpose of registering Securities and transfer of Securities as herein provided shall be appointed as authorized by Board Resolution or supplemental indenture (the “Security Registrar”).

      

      

      Upon surrender for transfer of any Security at the office or agency of the Company designated for such purpose, the Company shall execute, the Trustee shall authenticate and such office or agency
        shall deliver in the name of the transferee or transferees a new Security or Securities of the same series as the Security presented for a like aggregate principal amount.

      

      

      The Company initially appoints the Trustee as Security Registrar for each series of Securities.

      

      

      All Securities presented or surrendered for exchange or registration of transfer, as provided in this Section, shall be accompanied (if so required by the Company or the Security Registrar) by a
        written instrument or instruments of transfer, in form satisfactory to the Company or the Security Registrar, duly executed by the registered holder or by such holder’s duly authorized attorney in writing.

      

      

      (c)          Except as provided pursuant to Section 2.01 pursuant to a Board Resolution, and set forth in an Officer’s Certificate, or established in one or
        more indentures supplemental to this Indenture, no service charge shall be made for any exchange or registration of transfer of Securities, or issue of new Securities in case of partial redemption of any series or repurchase, conversion or exchange
        of less than the entire principal amount of a Security, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, other than exchanges pursuant to Section 2.06, Section 3.03(b) and
        Section 9.04 not involving any transfer.

      

      

      (d)          The Company and the Security Registrar shall not be required (i) to issue, exchange or register the transfer of any Securities during a period
        beginning at the opening of business 15 days before the day of the sending of a notice of redemption of less than all the Outstanding Securities of the same series and ending at the close of business on the day of such sending, nor (ii) to register
        the transfer of or exchange any Securities of any series or portions thereof called for redemption or surrendered for repurchase, but not validly withdrawn, other than the unredeemed portion of any such Securities being redeemed in part or not
        surrendered for repurchase, as the case may be.  The provisions of this Section 2.05 are, with respect to any Global Security, subject to Section 2.11 hereof.

      

      

      
        11

        
          

      

      The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to
        any transfer of any interest in any Security (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or
        evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

      

      

      Section 2.06          Temporary Securities.

      

      

      Pending the preparation of definitive Securities of any series, the Company may execute, and the Trustee shall authenticate and deliver, temporary Securities (printed, lithographed or typewritten)
        of any authorized denomination.  Such temporary Securities shall be substantially in the form of the definitive Securities in lieu of which they are issued, but with such omissions, insertions and variations as may be appropriate for temporary
        Securities, all as may be determined by the Company.  Every temporary Security of any series shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect,
        as the definitive Securities of such series.  Without unnecessary delay the Company will execute and will furnish definitive Securities of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange
        therefor (without charge to the Securityholders), at the office or agency of the Company designated for the purpose, and the Trustee shall authenticate and such office or agency shall deliver in exchange for such temporary Securities an equal
        aggregate principal amount of definitive Securities of such series, unless the Company advises the Trustee to the effect that definitive Securities need not be executed and furnished until further notice from the Company.  Until so exchanged, the
        temporary Securities of such series shall be entitled to the same benefits under this Indenture as definitive Securities of such series authenticated and delivered hereunder.

      

      

      Section 2.07          Mutilated, Destroyed, Lost or Stolen Securities.

      

      

      In case any temporary or definitive Security shall become mutilated or be destroyed, lost or stolen, the Company (subject to the next succeeding sentence) shall execute, and upon the Company’s
        request the Trustee (subject as aforesaid) shall authenticate and deliver, a new Security of the same series, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in
        substitution for the Security so destroyed, lost or stolen.  In every case the applicant for a substituted Security shall furnish to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless,
        and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee evidence to their satisfaction of the destruction, loss or theft of the applicant’s Security and of the ownership thereof.  The
        Trustee may authenticate any such substituted Security and deliver the same upon the written request or authorization of any officer of the Company.  Upon the issuance of any substituted Security, 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 Trustee) connected therewith.

      

      

      
        12

        
          

      

      In case any Security that has matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Security, pay or authorize the
        payment of the same (without surrender thereof except in the case of a mutilated Security) if the applicant for such payment shall furnish to the Company and the Trustee such security or indemnity as they may require to save them harmless, and, in
        case of destruction, loss or theft, evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of such Security and of the ownership thereof.

      

      

      Every replacement Security issued pursuant to the provisions of this Section shall constitute an additional contractual obligation of the Company whether or not the mutilated, destroyed, lost or
        stolen Security shall be found at any time, or be enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of the same series duly issued hereunder.  All
        Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities, and shall preclude (to the extent lawful) any
        and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

      

      

      Section 2.08          Cancellation.

      

      

      All Securities surrendered for the purpose of payment, redemption, repurchase, exchange, registration of transfer or conversion shall, if surrendered to the Company or any paying agent (or any
        other applicable agent), be delivered to the Trustee for cancellation, or, if surrendered to the Trustee, shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly required or permitted by any of the provisions
        of this Indenture.  On request of the Company at the time of such surrender, the Trustee shall deliver to the Company canceled Securities held by the Trustee.  In the absence of such request the Trustee may dispose of canceled Securities in
        accordance with its standard procedures and deliver a certificate of disposition to the Company.  If the Company shall otherwise acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the
        indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation.

      

      

      Section 2.09          Benefits of Indenture.

      

      

      Nothing in this Indenture or in the Securities, express or implied, shall give or be construed to give to any Person, other than the parties hereto and the holders of the Securities any legal or
        equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all such covenants, conditions and provisions being for the sole benefit of the parties hereto and of the
        holders of the Securities.

      

      

      
        13

        
          

      

      Section 2.10          Authenticating Agent.

      

      

      So long as any of the Securities of any series remain Outstanding there may be an Authenticating Agent for any or all such series of Securities which the Trustee shall have the right to appoint. 
        Said Authenticating Agent shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, transfer or partial redemption, repurchase or conversion thereof, and Securities so authenticated shall be
        entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.  All references in this Indenture to the authentication of Securities by the Trustee shall be deemed to
        include authentication by an Authenticating Agent for such series.  Each Authenticating Agent shall be acceptable to the Company and shall be a corporation that has a combined capital and surplus, as most recently reported or determined by it,
        sufficient under the laws of any jurisdiction under which it is organized or in which it is doing business to conduct a trust business, and that is otherwise authorized under such laws to conduct such business and is subject to supervision or
        examination by federal or state authorities.  If at any time any Authenticating Agent shall cease to be eligible in accordance with these provisions, it shall resign immediately.

      

      

      Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company.  The Trustee may at any time (and upon request by the Company shall)
        terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company.  Upon resignation, termination or cessation of eligibility of any Authenticating Agent, the Trustee may
        appoint an eligible successor Authenticating Agent acceptable to the Company.  Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder
        as if originally named as an Authenticating Agent pursuant hereto.

      

      

      Section 2.11          Global Securities.

      

      

      (a)          If the Company shall establish pursuant to Section 2.01 that the Securities of a particular series are to be issued as a Global Security, then
        the Company shall execute and the Trustee shall, in accordance with Section 2.04, authenticate and deliver, a Global Security that (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, all of the
        Outstanding Securities of such series, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction (or if the Depositary names the
        Trustee as its custodian, retained by the Trustee), and (iv) shall bear a legend substantially to the following effect: “Except as otherwise provided in Section 2.11 of the Indenture, this Security may be transferred, in whole but not in part, only
        to another nominee of the Depositary or to a successor Depositary or to a nominee of such successor Depositary.”

      

      

      (b)          Notwithstanding the provisions of Section 2.05, the Global Security of a series may be transferred, in whole but not in part and in the manner
        provided in Section 2.05, only to another nominee of the Depositary for such series, or to a successor Depositary for such series selected or approved by the Company or to a nominee of such successor Depositary.

      

      

      
        14

        
          

      

      (c)          If at any time the Depositary for a series of the Securities notifies the Company that it is unwilling or unable to continue as Depositary for
        such series or if at any time the Depositary for such series shall no longer be registered or in good standing under the Exchange Act, or other applicable statute or regulation, and a successor Depositary for such series is not appointed by the
        Company within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be, or if an Event of Default has occurred and is continuing and the Company has received a request from the Depositary or from the
        Trustee, this Section 2.11 shall no longer be applicable to the Securities of such series and the Company will execute, and subject to Section 2.04, the Trustee will authenticate and deliver the Securities of such series in definitive registered
        form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security.  In addition, the Company may at any time determine
        that the Securities of any series shall no longer be represented by a Global Security and that the provisions of this Section 2.11 shall no longer apply to the Securities of such series.  In such event the Company will execute and, subject to
        Section 2.04, the Trustee, upon receipt of an Officer’s Certificate evidencing such determination by the Company, will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized
        denominations, and in an aggregate principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security.  Upon the exchange of the Global Security for such Securities in definitive registered
        form without coupons, in authorized denominations, the Global Security shall be canceled by the Trustee.  Such Securities in definitive registered form issued in exchange for the Global Security pursuant to this Section 2.11(c) shall be registered
        in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee.  The Trustee shall deliver such Securities to the Depositary for
        delivery to the Persons in whose names such Securities are so registered.

      

      

      Section 2.12          CUSIP Numbers.

      

      

      The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to
        Securityholders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on
        the other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.  The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

      

      

      ARTICLE 3

      

      

      REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS

      

      

      Section 3.01          Redemption.

      

      

      The Company may redeem the Securities of any series issued hereunder on and after the dates and in accordance with the terms established for such series pursuant to Section 2.01 hereof.

      

      

      
        15

        
          

      

      Section 3.02          Notice of Redemption.

      

      

      (a)          In case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Securities of any series in
        accordance with any right the Company reserved for itself to do so pursuant to Section 2.01 hereof, the Company shall, or shall cause the Trustee to, give notice of such redemption to holders of the Securities of such series to be redeemed by
        mailing (or with regard to any Global Security held in book entry form, by electronic mail in accordance with the applicable procedures of the Depositary), a notice of such redemption not less than 30 days and not more than 90 days before the date
        fixed for redemption of that series to such Securityholders, unless a shorter period is specified in the Securities to be redeemed.  Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given,
        whether or not the registered holder receives the notice.  In any case, failure duly to give such notice to the holder of any Security of any series designated for redemption in whole or in part, or any defect in the notice, shall not affect the
        validity of the proceedings for the redemption of any other Securities of such series or any other series.  In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such
        Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with any such restriction.

      

      

      Each such notice of redemption shall identify the Securities to be redeemed (including CUSIP numbers, if any), specify the date fixed for redemption and the redemption price at which Securities of
        that series are to be redeemed, and shall state that payment of the redemption price of such Securities to be redeemed will be made at the office or agency of the Company, upon presentation and surrender of such Securities, that interest accrued to
        the date fixed for redemption will be paid as specified in said notice, that from and after said date interest will cease to accrue and that the redemption is from a sinking fund, if such is the case.  If less than all the Securities of a series
        are to be redeemed, the notice to the holders of Securities of that series to be redeemed in part shall specify the particular Securities to be so redeemed.

      

      

      In case any Security is to be redeemed in part only, the notice that relates to such Security shall state the portion of the principal amount thereof to be redeemed, and shall state that on and
        after the redemption date, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued.

      

      

      (b)          If less than all the Securities of a series are to be redeemed, the Company shall give the Trustee at least 45 days’ notice (unless a shorter
        notice shall be satisfactory to the Trustee) in advance of the date fixed for redemption as to the aggregate principal amount of Securities of the series to be redeemed, and thereupon the Securities to be redeemed shall be selected, by lot, on a
        pro rata basis, or in such other manner as the Company shall deem appropriate and fair in its discretion and that may provide for the selection of a portion or portions (equal to one thousand U.S. dollars ($1,000) or any integral multiple thereof)
        of the principal amount of such Securities of a denomination larger than $1,000, the Securities to be redeemed and shall thereafter promptly notify the Company in writing of the numbers of the Securities to be redeemed, in whole or in part.  The
        Company may, if and whenever it shall so elect, by delivery of instructions signed on its behalf by an Officer, instruct the Trustee or any paying agent to call all or any part of the Securities of a particular series for redemption and to give
        notice of redemption in the manner set forth in this Section, such notice to be in the name of the Company or its own name as the Trustee or such paying agent may deem advisable.  In any case in which notice of redemption is to be given by the
        Trustee or any such paying agent, the Company shall deliver or cause to be delivered to, or permit to remain with, the Trustee or such paying agent, as the case may be, such Security Register, transfer books or other records, or suitable copies or
        extracts therefrom, sufficient to enable the Trustee or such paying agent to give any notice by mail that may be required under the provisions of this Section.

      Section 3.03          Payment Upon Redemption.

      

      

      (a)          If the giving of notice of redemption shall have been completed as above provided, the Securities or portions of Securities of the series to be
        redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to, but excluding, the date fixed for redemption and interest on
        such Securities or portions of Securities shall cease to accrue on and after the date fixed for redemption, unless the Company shall default in the payment of such redemption price and accrued interest with respect to any such Security or portion
        thereof.  On presentation and surrender of such Securities on or after the date fixed for redemption at the place of payment specified in the notice, said Securities shall be paid and redeemed at the applicable redemption price for such series,
        together with interest accrued thereon to, but excluding, the date fixed for redemption (but if the date fixed for redemption is an Interest Payment Date, the interest installment payable on such date shall be payable to the registered holder at
        the close of business on the applicable record date pursuant to Section 2.03).

      

      

      (b)          Upon presentation of any Security of such series that is to be redeemed in part only, the Company shall execute and the Trustee shall
        authenticate and the office or agency where the Security is presented shall deliver to the Securityholder thereof, at the expense of the Company, a new Security of the same series of authorized denominations in principal amount equal to the
        unredeemed portion of the Security so presented.

      

      

      Section 3.04          Sinking Fund.

      

      

      The provisions of Sections 3.04, 3.05 and 3.06 shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise specified as contemplated by Section 2.01
        for Securities of such series.

      

      

      The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such
        minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment”.  If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject
        to reduction as provided in Section 3.05.  Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

      

      

      
        17

        
          

      

      Section 3.05          Satisfaction of Sinking Fund Payments with Securities.

      

      

      The Company (i) may deliver Outstanding Securities of a series and (ii) may apply as a credit Securities of a series that have been redeemed either at the election of the Company pursuant to the
        terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of
        such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series, provided that such Securities have not been previously so credited.  Such Securities shall be received and credited for such
        purpose by the Trustee at the redemption price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

      

      

      Section 3.06          Redemption of Securities for Sinking Fund.

      

      

      Not less than 45 days prior to each sinking fund payment date for any series of Securities (unless a shorter period shall be satisfactory to the Trustee), the Company will deliver to the Trustee an
        Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of the series, the portion thereof, if any, that is to be satisfied by delivering and crediting Securities of that series
        pursuant to Section 3.05 and the basis for such credit and will, together with such Officer’s Certificate, deliver to the Trustee any Securities to be so delivered.  Not less than 30 days before each such sinking fund payment date the Securities to
        be redeemed upon such sinking fund payment date shall be selected in the manner specified in Section 3.02 and the Company shall cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner
        provided in Section 3.02.  Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 3.03.

      The Company will duly and punctually pay or cause to be paid the principal of (and premium, if any) and interest on the Securities of that series at the time and place and in the manner provided
        herein and established with respect to such Securities. Payments of principal on the Securities may be made at the time provided herein and established with respect to such Securities by U.S. dollar check drawn on and mailed to the address of the
        Securityholder entitled thereto as such address shall appear in the Security Register, or U.S. dollar wire transfer to, a U.S. dollar account if such Securityholder shall have furnished wire instructions to the Trustee no later than 15 days prior
        to the relevant payment date. Payments of interest on the Securities may be made at the time provided herein and established with respect to such Securities by U.S. dollar check mailed to the address of the Securityholder entitled thereto as such
        address shall appear in the Security Register, or U.S. dollar wire transfer to, a U.S. dollar account if such Securityholder shall have furnished wire instructions in writing to the Security Registrar and the Trustee no later than 15 days prior to

      Section 4.02          Maintenance of Office or Agency.

      

      

      So long as any series of the Securities remain Outstanding, the Company agrees to maintain an office or agency with respect to each such series and at such other location or locations as may be
        designated as provided in this Section 4.02, where (i) Securities of that series may be presented for payment, (ii) Securities of that series may be presented as herein above authorized for registration of transfer and exchange, and (iii) notices
        and demands to or upon the Company in respect of the Securities of that series and this Indenture may be given or served, such designation to continue with respect to such office or agency until the Company shall, by written notice signed by any
        officer authorized to sign an Officer’s Certificate and delivered to the Trustee, designate some other office or agency for such purposes or any of them.  If at any time the Company shall fail to maintain any such required office or agency or shall
        fail to furnish the Trustee with the address thereof, such presentations, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such
        presentations, notices and demands.  The Company initially appoints the Corporate Trust Office of the Trustee as its paying agent with respect to the Securities.

      

      

      Section 4.03          Paying Agents.

      

      

      (a)          If the Company shall appoint one or more paying agents for all or any series of the Securities, other than the Trustee, the Company will cause
        each such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section:

      

      

      (1)          that it will hold all sums held by it as such agent for the payment of the principal of (and premium, if any) or interest on the Securities of
        that series (whether such sums have been paid to it by the Company or by any other obligor of such Securities) in trust for the benefit of the Persons entitled thereto;

      

      

      (2)         that it will give the Trustee notice of any failure by the Company (or by any other obligor of such Securities) to make any payment of the
        principal of (and premium, if any) or interest on the Securities of that series when the same shall be due and payable;

      

      

      (3)          that it will, at any time during the continuance of any failure referred to in the preceding paragraph (a)(2) above, upon the written request
        of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent; and

      

      

      (4)          that it will perform all other duties of paying agent as set forth in this Indenture.

      

      

      (b)          If the Company shall act as its own paying agent with respect to any series of the Securities, it will on or before each due date of the
        principal of (and premium, if any) or interest on Securities of that series, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay such principal (and premium, if any) or interest so becoming
        due on Securities of that series until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of such action, or any failure (by it or any other obligor on such Securities) to take
        such action.  Whenever the Company shall have one or more paying agents for any series of Securities, it will, prior to each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with the paying
        agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such paying agent is the
        Trustee) the Company will promptly notify the Trustee of this action or failure so to act.

      

      

      
        19

        
          

      

      (c)          Notwithstanding anything in this Section to the contrary, (i) the agreement to hold sums in trust as provided in this Section is subject to the
        provisions of Section 11.05, and (ii) the Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or direct any paying agent to pay, to the Trustee all sums held in trust
        by the Company or such paying agent, such sums to be held by the Trustee upon the same terms and conditions as those upon which such sums were held by the Company or such paying agent; and, upon such payment by the Company or any paying agent to
        the Trustee, the Company or such paying agent shall be released from all further liability with respect to such money.

      

      

      Section 4.04          Appointment to Fill Vacancy in Office of Trustee.

      

      

      The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so that there shall at all times be a Trustee
        hereunder.

      Section 5.01          Company to Furnish Trustee Names and Addresses of Securityholders.

      

      

      The Company will furnish or cause to be furnished to the Trustee (a) within 15 days after each regular record date (as defined in Section 2.03) a list, in such form as the Trustee may reasonably
        require, of the names and addresses of the holders of each series of Securities as of such regular record date, provided that the Company shall not be obligated to furnish or cause to furnish such list at any time that the list shall not differ in
        any respect from the most recent list furnished to the Trustee by the Company and (b) at such other times as the Trustee may request in writing within 30 days after the receipt by the Company of any such request, a list of similar form and content
        as of a date not more than 15 days prior to the time such list is furnished; provided, however, that, in either case, no such list need be furnished for any series for which the Trustee shall be the Security Registrar.

      Section 5.02          Preservation Of Information; Communications With Securityholders.

      

      

      (a)          The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the holders of
        Securities contained in the most recent list furnished to it as provided in Section 5.01 and as to the names and addresses of holders of Securities received by the Trustee in its capacity as Security Registrar (if acting in such capacity).

      

      

      (b)          The Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

      

      

      (c)          Securityholders may communicate as provided in Section 312(b) of the Trust Indenture Act with other Securityholders with respect to their rights
        under this Indenture or under the Securities, and, in connection with any such communications, the Trustee shall satisfy its obligations under Section 312(b) of the Trust Indenture Act in accordance with the provisions of Section 312(b) of the
        Trust Indenture Act.

      

      

      Section 5.03          Reports by the Company.

      

      

      (a)          The Company will at all times comply with Section 314(a) of the Trust Indenture Act.  The Company covenants and agrees to provide (which
        delivery may be via electronic mail) to the Trustee within 30 days, after the Company files the same with the Commission, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the
        foregoing as the Commission may from time to time by rules and regulations prescribe) that the Company is required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; provided, however, the Company shall not be
        required to deliver to the Trustee any correspondence filed with the Commission or any materials for which the Company has sought and received confidential treatment by the Commission; and provided further, that so long as such filings by the
        Company are available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (EDGAR), or any successor system, such filings shall be deemed to have been filed with the Trustee for purposes hereof without any further action
        required by the Company. For the avoidance of doubt, a failure by the Company to file annual reports, information and other reports with the Commission within the time period prescribed thereof by the Commission shall not be deemed a breach of this
        Section 5.03.

      

      

      (b)          Delivery of reports, information and documents to the Trustee under Section 5.03 is for informational purposes only and the information and the
        Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein including the Company’s compliance with any of their covenants thereunder (as to
        which the Trustee is entitled to rely exclusively on an Officer’s Certificate).  The Trustee is under no duty to examine any such reports, information or documents delivered to the Trustee or filed with the Commission via EDGAR to ensure compliance
        with the provision of this Indenture or to ascertain the correctness or otherwise of the information or the statements contained therein.  The Trustee shall have no responsibility or duty whatsoever to ascertain or determine whether the above
        referenced filings with the Commission on EDGAR (or any successor system) has occurred.

      (a)           If required by Section 313(a) of the Trust Indenture Act, the Trustee, within sixty (60) days after each May 1, shall send to the
        Securityholders a brief report dated as of such May 1, which complies with Section 313(a) of the Trust Indenture Act.

      

      

      (b)           The Trustee shall comply with Section 313(b) and 313(c) of the Trust Indenture Act.

      

      

      (c)           A copy of each such report shall, at the time of such transmission to Securityholders, be filed by the Trustee with the Company, with each
        securities exchange upon which any Securities are listed (if so listed) and also with the Commission.  The Company agrees to notify the Trustee when any Securities become listed on any securities exchange.

      DEFAULT

      

      

      Section 6.01          Events of Default.

      

      

      (a)          Whenever used herein with respect to Securities of a particular series, “Event of Default” means any one or more of the following events that
        has occurred and is continuing:

      

      

      (1)         the Company defaults in the payment of any installment of interest upon any of the Securities of that series, as and when the same shall become
        due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment period by the Company in accordance with the terms of any indenture supplemental hereto shall not constitute a
        default in the payment of interest for this purpose;

      

      

      (2)         the Company defaults in the payment of the principal of (or premium, if any, on) any of the Securities of that series as and when the same shall
        become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to that series; provided, however, that a valid extension of the maturity
        of such Securities in accordance with the terms of any indenture supplemental hereto shall not constitute a default in the payment of principal or premium, if any;

      

      

      (3)         the Company fails to observe or perform any other of its covenants or agreements with respect to that series contained in this Indenture or
        otherwise established with respect to that series of Securities pursuant to Section 2.01 hereof (other than a covenant or agreement that has been expressly included in this Indenture solely for the benefit of one or more series of Securities other
        than such series) for a period of 90 days after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a “Notice of Default” hereunder, shall have been given to the Company by the
        Trustee, by registered or certified mail, or to the Company and the Trustee by the holders of at least 25% in principal amount of the Securities of that series at the time Outstanding;

      

      

      
        22

        
          

      

      (4)          the Company pursuant to or within the meaning of any Bankruptcy Law (i) commences a voluntary case, (ii) consents to the entry of an order for
        relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property or (iv) makes a general assignment for the benefit of its creditors; or

      

      

      (5)          a court of competent jurisdiction enters an order under any Bankruptcy Law that (i) is for relief against the Company in an involuntary case,
        (ii) appoints a Custodian of the Company for all or substantially all of its property or (iii) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for 90 days.

      

      

      (b)          In each and every such case (other than an Event of Default specified in clause (4) or clause (5) above), unless the principal of all the
        Securities of that series shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Securities of that series then Outstanding hereunder, by notice in writing to the
        Company (and to the Trustee if given by such Securityholders), may declare the principal of (and premium, if any, on) and accrued and unpaid interest on all the Securities of that series to be due and payable immediately, and upon any such
        declaration the same shall become and shall be immediately due and payable.  If an Event of Default specified in clause (4) or clause (5) above occurs, the principal of and accrued and unpaid interest on all the Securities of that series shall
        automatically be immediately due and payable without any declaration or other act on the part of the Trustee or the holders of the Securities.

      

      

      (c)          At any time after the principal of (and premium, if any, on) and accrued and unpaid interest on the Securities of that series shall have been so
        declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the holders of a majority in aggregate principal amount of the Securities of that series then
        Outstanding hereunder, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (i) the Company has paid or deposited with the Trustee a sum sufficient to pay all matured installments of
        interest upon all the Securities of that series and the principal of (and premium, if any, on) any and all Securities of that series that shall have become due otherwise than by acceleration (with interest upon such principal and premium, if any,
        and, to the extent that such payment is enforceable under applicable law, upon overdue installments of interest, at the rate per annum expressed in the Securities of that series to the date of such payment or deposit) and the amount payable to the
        Trustee under Section 7.06, and (ii) any and all Events of Default under the Indenture with respect to such series, other than the nonpayment of principal on (and premium, if any, on) and accrued and unpaid interest on Securities of that series
        that shall not have become due by their terms, shall have been remedied or waived as provided in Section 6.06.

      

      

      No such rescission and annulment shall extend to or shall affect any subsequent default or impair any right consequent thereon.

      

      

      
        23

        
          

      

      (d)          In case the Trustee shall have proceeded to enforce any right with respect to Securities of that series under this Indenture and such
        proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case, subject to any determination in such
        proceedings, the Company and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceedings had been taken.

      

      

      Section 6.02          Collection of Indebtedness and Suits for Enforcement by Trustee.

      

      

      (a)          The Company covenants that (i) in case it shall default in the payment of any installment of interest on any of the Securities of a series, or
        in any payment required by any sinking or analogous fund established with respect to that series as and when the same shall have become due and payable, and such default shall have continued for a period of 90 days, or (ii) in case it shall default
        in the payment of the principal of (or premium, if any, on) any of the Securities of a series when the same shall have become due and payable, whether upon maturity of the Securities of a series or upon redemption or upon declaration or otherwise
        then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Securities of that series, the whole amount that then shall have been become due and payable on all such Securities for principal (and
        premium, if any) or interest, or both, as the case may be, with interest upon the overdue principal (and premium, if any) and (to the extent that payment of such interest is enforceable under applicable law) upon overdue installments of interest at
        the rate per annum expressed in the Securities of that series; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee under Section 7.06.

      

      

      (b)          If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, shall
        be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or
        final decree against the Company or other obligor upon the Securities of that series and collect the moneys adjudged or decreed to be payable in the manner provided by law or equity out of the property of the Company or other obligor upon the
        Securities of that series, wherever situated.

      

      

      (c)          In case of any receivership, insolvency, liquidation, bankruptcy, reorganization, readjustment, arrangement, composition or judicial proceedings
        affecting the Company, or its creditors or property, the Trustee shall have power to intervene in such proceedings and take any action therein that may be permitted by the court and shall (except as may be otherwise provided by law) be entitled to
        file such proofs of claim and other papers and documents as may be necessary or advisable in order to have the claims of the Trustee and of the holders of Securities of such series allowed for the entire amount due and payable by the Company under
        the Indenture at the date of institution of such proceedings and for any additional amount that may become due and payable by the Company after such date, and to collect and receive any moneys or other property payable or deliverable on any such
        claim, and to distribute the same after the deduction of the amount payable to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the holders of Securities of such
        series to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to such Securityholders, to pay to the Trustee any amount due it under Section 7.06.

      

      

      
        24

        
          

      

      (d)          All rights of action and of asserting claims under this Indenture, or under any of the terms established with respect to Securities of that
        series, may be enforced by the Trustee without the possession of any of such Securities, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its
        own name as trustee of an express trust, and any recovery of judgment shall, after provision for payment to the Trustee of any amounts due under Section 7.06, be for the ratable benefit of the holders of the Securities of such series.

      

      

      In case of an Event of Default hereunder, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the
        Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the
        exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

      

      

      Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment
        or composition affecting the Securities of that series or the rights of any Securityholder thereof or to authorize the Trustee to vote in respect of the claim of any Securityholder in any such proceeding.

      

      

      Section 6.03          Application of Moneys Collected.

      

      

      Any moneys collected by the Trustee pursuant to this Article with respect to a particular series of Securities shall be applied in the following order, at the date or dates fixed by the Trustee
        and, in case of the distribution of such moneys on account of principal (or premium, if any) or interest, upon presentation of the Securities of that series, and notation thereon of the payment, if only partially paid, and upon surrender thereof if
        fully paid:

      

      

      FIRST: To the payment of costs and expenses of collection and of all amounts payable to the Trustee under Section 7.06;

      

      

      SECOND: To the payment of the amounts then due and unpaid upon Securities of such series for principal (and premium, if any) and interest, in respect of which or for the benefit of which such money
        has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; and

      

      

      THIRD: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto.

      Section 6.04          Limitation on Suits.

      

      

      No holder of any Security of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or
        under or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (i) such Securityholder previously shall have given to the Trustee written notice of an Event of Default and of the
        continuance thereof with respect to the Securities of such series specifying such Event of Default, as hereinbefore provided; (ii) the holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding
        shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; (iii) such Securityholder or Securityholders shall have offered to the Trustee indemnity satisfactory to it against
        the costs, expenses and liabilities to be incurred in compliance with such request; (iv) the Trustee for 90 days after its receipt of such notice, request and offer of indemnity, shall have failed to institute any such action, suit or proceeding
        and (v) during such 90 day period, the holders of a majority in principal amount of the Securities of that series do not give the Trustee a direction inconsistent with the request.

      

      

      Notwithstanding anything contained herein to the contrary or any other provisions of this Indenture, the right of any holder of any Security to receive payment of the principal of (and premium, if
        any) and interest on such Security, as therein provided, on or after the respective due dates expressed in such Security (or in the case of redemption, on the redemption date), or to institute suit for the enforcement of any such payment on or
        after such respective dates or redemption date, shall not be impaired or affected without the consent of such holder and by accepting a Security hereunder it is expressly understood, intended and covenanted by the taker and holder of every Security
        of such series with every other such taker and holder and the Trustee, that no one or more holders of Securities of such series shall have any right in any manner whatsoever by virtue or by availing of any provision of this Indenture to affect,
        disturb or prejudice the rights of the holders of any other of such Securities, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided
        and for the equal, ratable and common benefit of all holders of Securities of such series.  For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can
        be given either at law or in equity.

      

      

      Section 6.05          Rights and Remedies Cumulative; Delay or Omission Not Waiver.

      

      

      (a)          Except as otherwise provided in Section 2.07, all powers and remedies given by this Article to the Trustee or to the Securityholders shall, to
        the extent permitted by law, be deemed cumulative and not exclusive of any other powers and remedies available to the Trustee or the holders of the Securities, by judicial proceedings or otherwise, to enforce the performance or observance of the
        covenants and agreements contained in this Indenture or otherwise established with respect to such Securities.

      

      

      (b)          No delay or omission of the Trustee or of any holder of any of the Securities to exercise any right or power accruing upon any Event of Default
        occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of Section 6.04, every power and remedy given by this
        Article or by law to the Trustee or the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Securityholders.

      Section 6.06          Control by Securityholders.

      

      

      The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding, determined in accordance with Section 8.04, shall have the right to direct the time,
        method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to such series; provided, however, that such direction shall not be in conflict with any
        rule of law or with this Indenture or subject the Trustee in its sole discretion to personal liability.  Subject to the provisions of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in good
        faith shall, by a Responsible Officer or officers of the Trustee, determine that the proceeding so directed, subject to the Trustee’s duties under the Trust Indenture Act, would involve the Trustee in personal liability or might be unduly
        prejudicial to the Securityholders not involved in the proceeding.  The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding affected thereby, determined in accordance with Section 8.04, may on
        behalf of the holders of all of the Securities of such series waive any past default in the performance of any of the covenants contained herein or established pursuant to Section 2.01 with respect to such series and its consequences, except a
        default in the payment of the principal of, or premium, if any, or interest on, any of the Securities of that series as and when the same shall become due by the terms of such Securities otherwise than by acceleration (unless such default has been
        cured and a sum sufficient to pay all matured installments of interest and principal and any premium has been deposited with the Trustee (in accordance with Section 6.01(c)).  Upon any such waiver, the default covered thereby shall be deemed to be
        cured for all purposes of this Indenture and the Company, the Trustee and the holders of the Securities of such series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent
        or other default or impair any right consequent thereon.

      

      

      Section 6.07          Undertaking to Pay Costs.

      

      

      All parties to this Indenture agree, and each holder of any Securities by such holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit
        for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and
        that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party
        litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of Securityholders, holding more than 10% in aggregate principal amount of the Outstanding
        Securities of any series, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security of such series, on or after the respective due dates expressed in such
        Security or established pursuant to this Indenture.

      ARTICLE 7

      

      

      CONCERNING THE TRUSTEE

      

      

      Section 7.01          Certain Duties and Responsibilities of Trustee.

      

      

      (a)          The Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing of all Events of
        Default with respect to the Securities of that series that may have occurred, shall undertake to perform with respect to the Securities of such series such duties and only such duties as are specifically set forth in this Indenture, and no implied
        covenants shall be read into this Indenture against the Trustee.  In case an Event of Default with respect to the Securities of a series has occurred (that has not been cured or waived), the Trustee shall exercise with respect to Securities of that
        series such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his or her own affairs.

      

      

      (b)          No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure
        to act, or its own willful misconduct, except that:

      

      

      (i)          prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing or waiving of all such Events of
        Default with respect to that series that may have occurred:

      

      

      (A)        the duties and obligations of the Trustee shall with respect to the Securities of such series be determined solely by the express provisions of
        this Indenture, and the Trustee shall not be liable with respect to the Securities of such series except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations
        shall be read into this Indenture against the Trustee; and

      

      

      (B)          in the absence of bad faith on the part of the Trustee, the Trustee may with respect to the Securities of such series conclusively rely, as to
        the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions
        that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

      

      

      (ii)          the Trustee shall not be liable to any Securityholder or to any other Person for any error of judgment made in good faith by a Responsible
        Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

      

      

      
        28

        
          

      

      (iii)          the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction
        of the holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any
        trust or power conferred upon the Trustee under this Indenture with respect to the Securities of that series;

      

      

      (iv)          none of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal
        financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or liability is not reasonably assured to it under the terms
        of this Indenture or adequate indemnity against such risk is not reasonably assured to it;

      

      

      (v)          The Trustee shall not be required to give any bond or surety in respect of the performance of its powers or duties hereunder;

      

      

      (vi)          The permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty of the Trustee; and

      

      

      (vii)          No Trustee shall have any duty or responsibility for any act or omission of any other Trustee appointed with respect to a series of Securities
        hereunder.

      

      

      Section 7.02          Certain Rights of Trustee.

      

      

      Except as otherwise provided in Section 7.01:

      

      

      (a)          The Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement,
        instrument, opinion, report, notice, request, consent, order, approval, bond, security or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

      

      

      (b)          Any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by a Board Resolution or an instrument
        signed in the name of the Company by any authorized Officer of the Company (unless other evidence in respect thereof is specifically prescribed herein);

      

      

      (c)          The Trustee may consult with counsel and the opinion or written advice of such counsel or, if requested, any Opinion of Counsel shall be full
        and complete authorization and protection in respect of any action taken or suffered or omitted hereunder in good faith and in reliance thereon;

      

      

      (d)          The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or
        direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee security or indemnity reasonably acceptable to the Trustee against the costs, expenses and
        liabilities that may be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default with respect to a series of the Securities (that has not been cured or
        waived), to exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the
        circumstances in the conduct of his or her own affairs;

      

      

      
        29

        
          

      

      (e)          The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith and believed by it to be authorized or within
        the discretion or rights or powers conferred upon it by this Indenture;

      

      

      (f)          The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
        opinion, report, notice, request, consent, order, approval, bond, security, or other papers or documents or inquire as to the performance by the Company of one of its covenants under this Indenture, unless requested in writing so to do by the
        holders of not less than a majority in principal amount of the Outstanding Securities of the particular series affected thereby (determined as provided in Section 8.04); provided, however, that if the payment within a reasonable time to the Trustee
        of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the
        Trustee may require security or indemnity reasonably acceptable to the Trustee against such costs, expenses or liabilities as a condition to so proceeding.  The reasonable expense of every such examination shall be paid by the Company or, if paid
        by the Trustee, shall be repaid by the Company upon demand;

      

      

      (g)          The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or
        attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

      

      

      (h)          In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of
        or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and
        interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to
        resume performance as soon as practicable under the circumstances;

      

      

      (i)          In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever
        (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action;

      

      

      (j)          The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, facsimile transmission
        or other similar unsecured electronic methods; provided, however, that such instructions or directions shall be signed by an authorized representative of the party providing such instructions or directions.  If the party elects to give the Trustee
        e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling.  The Trustee
        shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written
        instruction.  The party providing electronic instructions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting
        on unauthorized instructions, and the risk or interception and misuse by third parties.  The Trustee may request that the Company deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such
        time to furnish the Trustee with Officer’s Certificates, Company Orders and any other matters or directions pursuant to this Indenture;

      

      

      
        30

        
          

      

      (k)          The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified,
        are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder and under the Securities, and each agent, custodian or other person employed to act under this Indenture; and

      

      

      (l)          The Trustee shall not be deemed to have knowledge of any Default or Event of Default (other than an Event of Default constituting the failure to
        pay the interest on, or the principal of, the Securities if the Trustee also serves as the paying agent for such Securities) until the Trustee shall have received written notification in the manner set forth in this Indenture or a Responsible
        Officer of the Trustee shall have obtained actual knowledge.

      

      

      Section 7.03          Trustee Not Responsible for Recitals or Issuance or Securities.

      

      

      (a)          The recitals contained herein and in the Securities shall be taken as the statements of the Company, and the Trustee assumes no responsibility
        for the correctness of the same.  The Trustee shall not be responsible for any statement in any registration statement, prospectus, or any other document in connection with the sale of Securities. The Trustee shall not be responsible for any rating
        on the Securities or any action or omission of any rating agency.

      

      

      (b)          The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities.

      

      

      (c)          The Trustee shall not be accountable for the use or application by the Company of any of the Securities or of the proceeds of such Securities,
        or for the use or application of any moneys paid over by the Trustee in accordance with any provision of this Indenture or established pursuant to Section 2.01, or for the use or application of any moneys received by any paying agent other than the
        Trustee.

      

      

      Section 7.04          May Hold Securities.

      

      

      The Trustee or any paying agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not
        Trustee, paying agent or Security Registrar.

      

      

      
        31

        
          

      

      Section 7.05          Moneys Held in Trust.

      

      

      Subject to the provisions of Section 11.05, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but
        need not be segregated from other funds except to the extent required by law.  The Trustee shall be under no liability for interest on any moneys received by it hereunder except such as it may agree with the Company to pay thereon.

      

      

      Section 7.06          Compensation and Reimbursement.

      

      

      (a)           The Company shall pay to the Trustee for each of its capacities hereunder from time to time compensation for its services as the Company and
        the Trustee shall from time to time agree upon in writing.  The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.  The Company shall reimburse the Trustee upon request for all reasonable
        out-of-pocket expenses incurred by it.  Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel.

      

      

      (b)          The Company shall indemnify each of the Trustee in each of its capacities hereunder against any loss, liability or expense (including the cost
        of defending itself and including the reasonable compensation and expenses of the Trustee’s agents and counsel) incurred by it except as set forth in Section 7.06(c) in the exercise or performance of its powers, rights or duties under this
        Indenture as Trustee or Agent.  The Trustee shall notify the Company promptly of any claim for which it may seek indemnity.  The Company shall defend the claim and the Trustee shall cooperate in the defense.  The Trustee may have one separate
        counsel and the Company shall pay the reasonable fees and expenses of such counsel.  The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.  This indemnification shall apply to
        officers, directors, employees, shareholders and agents of the Trustee.

      

      

      (c)          The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director,
        employee, shareholder or agent of the Trustee through negligence or bad faith.

      

      

      (d)          To ensure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all funds or property held
        or collected by the Trustee, except that held in trust to pay principal of or interest on particular Securities.  When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(4) or (5), the
        expenses (including the reasonable fees and expenses of its counsel) and the compensation for services in connection therewith are to constitute expenses of administration under any bankruptcy law.  The provisions of this Section 7.06 shall survive
        the termination of this Indenture and the resignation or removal of the Trustee.

      

      

      Section 7.07          Reliance on Officer’s Certificate.

      

      

      Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it reasonably necessary or desirable that a matter be proved
        or established prior to taking or suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the
        Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for
        any action taken, suffered or omitted to be taken by it under the provisions of this Indenture upon the faith thereof.

      Section 7.08          Disqualification; Conflicting Interests.

      

      

      If the Trustee has or shall acquire any “conflicting interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the Company shall in all respects comply with the
        provisions of Section 310(b) of the Trust Indenture Act.

      

      

      Section 7.09          Corporate Trustee Required; Eligibility.

      

      

      There shall at all times be a Trustee with respect to the Securities issued hereunder which shall at all times be a corporation organized and doing business under the laws of the United States of
        America or any state or territory thereof or of the District of Columbia, or a corporation or other Person permitted to act as trustee by the Commission, authorized under such laws to exercise corporate trust powers, having a combined capital and
        surplus of at least fifty million U.S. dollars ($50,000,000), and subject to supervision or examination by federal, state, territorial, or District of Columbia authority.

      

      

      If such corporation or other Person publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the
        purposes of this Section, the combined capital and surplus of such corporation or other Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.  The Company may not, nor may
        any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee.  In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee
        shall resign immediately in the manner and with the effect specified in Section 7.10.

      

      

      Section 7.10          Resignation and Removal; Appointment of Successor.

      

      

      (a)          The Trustee or any successor hereafter appointed may at any time resign with respect to the Securities of one or more series by giving written
        notice thereof to the Company and the Securityholders of such series. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee with respect to Securities of such series by written instrument, in duplicate,
        executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee.  If no successor trustee shall have been so appointed and have accepted appointment within
        30 days after the sending of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to Securities of such series, or any Securityholder of that
        series who has been a bona fide holder of a Security or Securities for at least six months may on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee.  Such court may thereupon
        after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

      

      

      
        33

        
          

      

      (b)          In case at any time any one of the following shall occur:

      

      

      (i)          the Trustee shall fail to comply with the provisions of Section 7.08 after written request therefor by the Company or by any Securityholder who
        has been a bona fide holder of a Security or Securities for at least six months; or

      

      

      (ii)          the Trustee shall cease to be eligible in accordance with the provisions of Section 7.09 and shall fail to resign after written request
        therefor by the Company or by any such Securityholder; or

      

      

      (iii)         the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding, or
        a receiver of the Trustee or of its property shall be appointed or consented to, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

      

      

      then, in any such case, the Company may remove the Trustee with respect to all Securities and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of
        Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or any Securityholder who has been a bona fide holder of a Security or Securities for at least six months may, on behalf of
        that holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.  Such court may thereupon after such notice, if any, as it may deem proper and
        prescribe, remove the Trustee and appoint a successor trustee.

      

      

      (c)          The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding may at any time remove the
        Trustee with respect to such series by so notifying the Trustee and the Company and may appoint a successor Trustee for such series with the consent of the Company.

      

      

      (d)          Any resignation or removal of the Trustee and appointment of a successor trustee with respect to the Securities of a series pursuant to any of
        the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11.

      

      

      (e)            Any successor trustee appointed pursuant to this Section may be appointed with respect to the Securities of one or more series or all of such
        series, and at any time there shall be only one Trustee with respect to the Securities of any particular series.

      

      

      Section 7.11          Acceptance of Appointment By Successor.

      

      

      (a)            In case of the appointment hereunder of a successor trustee with respect to all Securities, every such successor trustee so appointed shall
        execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor trustee, without any
        further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor trustee, such retiring Trustee shall, upon payment of any amounts due
        to it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights, powers, and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor
        trustee all property and money held by such retiring Trustee hereunder.

      

      

      
        34

        
          

      

      (b)           In case of the appointment hereunder of a successor trustee with respect to the Securities of one or more (but not all) series, the Company,
        the retiring Trustee and each successor trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor trustee shall accept such appointment and which (i) shall contain
        such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which
        the appointment of such successor trustee relates, (ii) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that
        or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the
        administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee shall be trustee of a
        trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; and upon the
        execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall with respect to the Securities of that or those series to
        which the appointment of such successor trustee relates have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture, and each such successor
        trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor
        trustee relates; but, on request of the Company or any successor trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor trustee, to the extent contemplated by such supplemental indenture, the property and money
        held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor trustee relates.

      

      

      (c)            Upon request of any such successor trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and
        confirming to such successor trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

      

      

      (d)           No successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee shall be qualified and eligible
        under this Article.

      

      

      
        35

        
          

      

      (e)          Upon acceptance of appointment by a successor trustee as provided in this Section, the Company shall send notice of the succession of such
        trustee hereunder to the Securityholders.  If the Company fails to send such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be sent at the expense of the Company.

      

      

      Section 7.12          Merger, Conversion, Consolidation or Succession to Business.

      

      

      Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the
        Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, including the administration of the trust created by this Indenture, shall be the successor of the Trustee hereunder,
        provided that such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09, without the execution or filing of any paper or any further act on the part of any of the parties hereto,
        anything herein to the contrary notwithstanding.  In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt
        such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

      

      

      Section 7.13          Preferential Collection of Claims Against the Company.

      

      

      The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act.  A Trustee who has resigned or
        been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein.

      

      

      Section 7.14          Notice of Default.

      

      

      If any Event of Default occurs and is continuing and if such Event of Default is known to a Responsible Officer of the Trustee, the Trustee shall send  to each Securityholder in the manner and to
        the extent provided in Section 313(c) of the Trust Indenture Act notice of the Event of Default within the earlier of 90 days after it occurs and 30 days after it is known to a Responsible Officer of the Trustee or written notice of it is received
        by the Trustee, unless such Event of Default has been cured; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on any Security, the
        Trustee shall be protected in withholding such notice if and so long as the Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Securityholders.

      ARTICLE 8

      

      

      CONCERNING THE SECURITYHOLDERS

      

      

      Section 8.01          Evidence of Action by Securityholders.

      

      

      Whenever in this Indenture it is provided that the holders of a majority or specified percentage in aggregate principal amount of the Securities of a particular series may take any action
        (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action the holders of such majority or specified percentage of that series
        have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such holders of Securities of that series in person or by agent or proxy appointed in writing.

      

      

      If the Company shall solicit from the Securityholders of any series any request, demand, authorization, direction, notice, consent, waiver or other action, the Company may, at its option, as
        evidenced by an Officer’s Certificate, fix in advance a record date for such series for the determination of Securityholders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company
        shall have no obligation to do so.  If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given before or after the record date, but only the Securityholders of record at the
        close of business on the record date shall be deemed to be Securityholders for the purposes of determining whether Securityholders of the requisite proportion of Outstanding Securities of that series have authorized or agreed or consented to such
        request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Securities of that series shall be computed as of the record date; provided, however, that no such authorization, agreement or
        consent by such Securityholders on the record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

      

      

      Section 8.02          Proof of Execution by Securityholders.

      

      

      Subject to the provisions of Section 7.01, proof of the execution of any instrument by a Securityholder (such proof will not require notarization) or his or her agent or proxy and proof of the
        holding by any Person of any of the Securities shall be sufficient if made in the following manner:

      

      

      (a)          The fact and date of the execution by any such Person of any instrument may be proved in any reasonable manner acceptable to the Trustee.

      

      

      (b)          The ownership of Securities shall be proved by the Security Register of such Securities or by a certificate of the Security Registrar thereof.

      

      

      The Trustee may require such additional proof of any matter referred to in this Section as it shall deem necessary.

      Section 8.03          Who May be Deemed Owners.

      

      

      Prior to the due presentment for registration of transfer of any Security, the Company, the Trustee, any paying agent and any Security Registrar may deem and treat the Person in whose name such
        Security shall be registered upon the books of the Security Registrar as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the
        Security Registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.03) interest on such Security and for all other purposes; and neither the Company nor the Trustee nor any
        paying agent nor any Security Registrar shall be affected by any notice to the contrary.

      

      

      Section 8.04          Certain Securities Owned by Company Disregarded.

      

      

      In determining whether the holders of the requisite aggregate principal amount of Securities of a particular series have concurred in any direction, consent or waiver under this Indenture, the
        Securities of that series that are owned by the Company or any other obligor on the Securities of that series or by any Person directly or indirectly controlling or controlled by or under common control with the Company or any other obligor on the
        Securities of that series shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent
        or waiver, only Securities of such series that the Trustee actually knows are so owned shall be so disregarded.  The Securities so owned that have been pledged in good faith may be regarded as Outstanding for the purposes of this Section, if the
        pledgee shall establish to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not a Person directly or indirectly controlling or controlled by or under direct or indirect common
        control with the Company or any such other obligor.  In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.

      

      

      Section 8.05          Actions Binding on Future Securityholders.

      

      

      At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the holders of the majority or percentage in aggregate principal
        amount of the Securities of a particular series specified in this Indenture in connection with such action, any holder of a Security of that series that is shown by the evidence to be included in the Securities the holders of which have consented
        to such action may, by filing written notice with the Trustee, and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Security.  Except as aforesaid any such action taken by the holder of any Security
        shall be conclusive and binding upon such holder and upon all future holders and owners of such Security, and of any Security issued in exchange therefor, on registration of transfer thereof or in place thereof, irrespective of whether or not any
        notation in regard thereto is made upon such Security.  Any action taken by the holders of the majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection with such action
        shall be conclusively binding upon the Company, the Trustee and the holders of all the Securities of that series.

      Section 9.01          Supplemental Indentures Without the Consent of Securityholders.

      

      

      In addition to any supplemental indenture otherwise authorized by this Indenture, the Company and the Trustee may from time to time and at any time enter into an indenture or indentures
        supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as then in effect), without the consent of the Securityholders, for one or more of the following purposes:

      

      

      (a)          to cure any ambiguity, defect, or inconsistency herein or in the Securities of any series;

      

      

      (b)          to comply with Article Ten;

      

      

      (c)          to provide for uncertificated Securities in addition to or in place of certificated Securities;

      

      

      (d)          to add to the covenants, restrictions, conditions or provisions relating to the Company for the benefit of the holders of all or any series of
        Securities (and if such covenants, restrictions, conditions or provisions are to be for the benefit of less than all series of Securities, stating that such covenants, restrictions, conditions or provisions are expressly being included solely for
        the benefit of such series), to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default, or to surrender any right or power herein
        conferred upon the Company;

      

      

      (e)          to add to, delete from, or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue,
        authentication, and delivery of Securities, as herein set forth;

      

      

      (f)          to make any change that does not adversely affect the rights of any Securityholder in any material respect;

      

      

      (g)          to provide for the issuance of and establish the form and terms and conditions of the Securities of any series as provided in Section 2.01, to
        establish the form of any certifications required to be furnished pursuant to the terms of this Indenture or any series of Securities, or to add to the rights of the holders of any series of Securities;

      

      

      (h)          to evidence and provide for the acceptance of appointment hereunder by a successor trustee; or

      

      

      (i)          to comply with any requirements of the Commission or any successor in connection with the qualification of this Indenture under the Trust
        Indenture Act.

      

      

      The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, and to make any further appropriate agreements and stipulations that may be therein
        contained, but the Trustee shall not be obligated to enter into any such supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

      

      

      
        39

        
          

      

      Any supplemental indenture authorized by the provisions of this Section may be executed by the Company and the Trustee without the consent of the holders of any of the Securities at the time
        Outstanding, notwithstanding any of the provisions of Section 9.02.

      

      

      Section 9.02          Supplemental Indentures With Consent of Securityholders.

      

      

      With the consent (evidenced as provided in Section 8.01) of the holders of not less than a majority in aggregate principal amount of the Securities of each series affected by such supplemental
        indenture or indentures at the time Outstanding, the Company, when authorized by a Board Resolution, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto (which shall conform to the
        provisions of the Trust Indenture Act as then in effect) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner not
        covered by Section 9.01 the rights of the holders of the Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the holders of each Security then Outstanding and affected
        thereby, (a) extend the fixed maturity of any Securities of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof or (b)
        reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture.

      

      

      It shall not be necessary for the consent of the Securityholders of any series affected thereby under this Section to approve the particular form of any proposed supplemental indenture, but it
        shall be sufficient if such consent shall approve the substance thereof.

      

      

      Section 9.03          Effect of Supplemental Indentures.

      

      

      Upon the execution of any supplemental indenture pursuant to the provisions of this Article or of Section 10.01, this Indenture shall, with respect to such series, be and be deemed to be modified
        and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the holders of Securities of the series affected thereby shall thereafter
        be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this
        Indenture for any and all purposes.

      

      

      Section 9.04          Securities Affected by Supplemental Indentures.

      

      

      Securities of any series affected by a supplemental indenture, authenticated and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article or of
        Section 10.01, may bear a notation in form approved by the Company, provided such form meets the requirements of any securities exchange upon which such series may be listed, as to any matter provided for in such supplemental indenture.  If the
        Company shall so determine, new Securities of that series so modified as to conform, in the opinion of the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the Company,
        authenticated by the Trustee and delivered in exchange for the Securities of that series then Outstanding.

      Section 9.05          Execution of Supplemental Indentures.

      

      

      Upon the request of the Company, accompanied by its Board Resolutions authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent
        of Securityholders required to consent thereto as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under
        this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. The Trustee, subject to the provisions of Section 7.01, shall receive an Officer’s Certificate or an
        Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article is authorized or permitted by the terms of this Article and that all conditions precedent to the execution of the supplemental indenture
        have been complied with; provided, however, that such Officer’s Certificate or Opinion of Counsel need not be provided in connection with the execution of a supplemental indenture that establishes the terms of a series of Securities pursuant to
        Section 2.01 hereof.

      

      

      Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Company shall (or shall direct the Trustee to) send a
        notice, setting forth in general terms the substance of such supplemental indenture, to the Securityholders of all series affected thereby .as their names and addresses appear upon the Security Register. Any failure of the Company to send, or cause
        the sending of, such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

        substantially as an entirety, to any other Person (whether or not affiliated with the Company or its successor or successors); provided, however, the Company hereby covenants and agrees that, upon any such consolidation or merger (in each case, if
        the Company is not the survivor of such transaction) or any such sale, conveyance, transfer or other disposition (other than a sale, conveyance, transfer or other disposition to a Subsidiary of the Company), the due and punctual payment of the
        principal of (premium, if any) and interest on all of the Securities of all series in accordance with the terms of each series, according to their tenor, and the due and punctual performance and observance of all the covenants and conditions of

        Trustee for cancellation, including principal (and premium, if any) and interest due or to become due to such date of maturity or date fixed for redemption, as the case may be, and if the Company shall also pay or cause to be paid all other sums
        payable hereunder by the Company with respect to such series, then after the date such moneys or Governmental Obligations, as the case may be, are deposited with the Trustee the obligations of the Company under this Indenture with respect to such
        series shall cease to be of further effect except for the provisions of Sections 2.03, 2.05, 2.07, 4,01, 4.02, 4,03, 7.06, 7.10, 11.05 and 13.04hereof that shall survive until such Securities shall mature and be paid.

        the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

        catastrophes or acts of God, and interruptions, loss or malfunctions or utilities, communications or computer (software and hardware) services; it being understood that the Trustee, the Security Registrar, any paying agent or any other agent under

    [●], As Warrant Agent

    

    

    Form of Common Stock

    Warrant Agreement

    

    

    Dated As Of [●]

    

    

    

    

    

    

    

    

    
      
        

    

    
    

    

    Bionano Genomics, Inc.

    

    

    Form of Common Stock Warrant Agreement

    

    

    This Common Stock Warrant Agreement (this “Agreement”), dated as of [●], between Bionano Genomics, 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 $0.0001 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.

    

    

    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.

    

    

    
      1

      
        

    

    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.

    

    

    ARTICLE 2

    

    

    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.

    

    

    
      2

      
        

    

    (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.

    

    

    ARTICLE 3

    

    

    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

      
        

    

    3.3          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.

    

    

    (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.

    

    

    
      4

      
        

    

    (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.

    

    

    (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.

    

    

    
      5

      
        

    

    (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.

    

    

    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)          “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.

    

    

    (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.]

    ARTICLE 4

    

    

    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.

    

    

    ARTICLE 5

    

    

    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.

    

    

    
      7

      
        

    

    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.

    

    

    (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.

    

    

    
      8

      
        

    

    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.

    

    

    (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.

    This certifies that [●] or registered assigns is the registered owner of the above indicated number of Warrants, each Warrant entitling such owner  to purchase, at any
      time [after [●] p.m., [City] time, [on [●] and] on or before [●] p.m., [City] time, on [●], [●] shares of Common Stock, par value $0.0001 per share (the “Warrant Securities”), of
      Bionano Genomics, Inc. (the “Company”) on the following basis: during the period from [●], through and including [●], the exercise price per Warrant Security will be $[●], subject to adjustment as provided in the Warrant Agreement (as hereinafter defined) (the “Warrant Price”).  The Holder may exercise the Warrants evidenced hereby by providing certain information set forth on the back hereof 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 this Warrant is exercised to the Warrant Agent
      (as hereinafter defined) and by surrendering this Warrant Certificate, with the purchase form on the back hereof duly executed, at the corporate trust office of [name of Warrant Agent], or its successor as warrant agent (the “Warrant Agent”), which is, on the date hereof, at the address specified on the reverse hereof, and upon compliance with and subject to the conditions set forth herein and in the Warrant
      Agreement (as hereinafter defined).

    

    

    The term “Holder” as used herein shall mean the person in whose name at the time this Warrant Certificate shall be registered upon the books to be maintained
      by the Warrant Agent for that purpose pursuant to Section 4 of the Warrant Agreement.

    

    

    The Warrants evidenced by this Warrant Certificate may be exercised to purchase a whole number of Warrant Securities in registered form.  Upon any exercise of fewer than all of the Warrants evidenced by this Warrant
      Certificate, there shall be issued to the Holder hereof a new Warrant Certificate evidencing Warrants for the number of Warrant Securities remaining unexercised.

    

    

    This Warrant Certificate is issued under and in accordance with the Warrant Agreement dated as of [●] (the “Warrant
        Agreement”), between the Company and the Warrant Agent and is subject to the terms and provisions contained in the Warrant Agreement, to all of which terms and provisions the Holder of this Warrant Certificate consents by acceptance hereof. 
      Copies of the Warrant Agreement are on file at the above-mentioned office of the Warrant Agent.

    

    

    Transfer of this Warrant Certificate may be registered when this Warrant Certificate is surrendered at the corporate trust office of the Warrant Agent by the registered owner or such owner’s assigns, in the manner and
      subject to the limitations provided in the Warrant Agreement.

    

    

    After countersignature by the Warrant Agent and prior to the expiration of this Warrant Certificate, this Warrant Certificate may be exchanged at the corporate trust office of the Warrant Agent for Warrant Certificates
      representing Warrants for the same aggregate number of Warrant Securities.

    

    

    This Warrant Certificate shall not entitle the Holder hereof to any of the rights of a holder of the Warrant Securities, including, without limitation, the right to receive payments of dividends or distributions, if
      any, on the Warrant Securities (except to the extent set forth in the Warrant Agreement) or to exercise any voting rights.

    

    

    Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

    

    

    This Warrant Certificate shall not be valid or obligatory for any purpose until countersigned by the Warrant Agent.
