      The Trustee acknowledges such Grants, accepts the trusts hereunder in accordance with the provisions hereof, and agrees to perform the

        -51-

        
          


      

      (ii)          The Notes

      Agent Members shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Note
          Administrator, as custodian for the Depository or under the Global Note, and the Depository may be treated by the Issuer, the Co-Issuer, the Trustee, the Note Administrator, the Collateral Manager, the Servicer and the Special Servicer and any of
          their respective agents as the absolute owner of such Global Note for all purposes whatsoever.  Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Co-Issuer, the Trustee, the Note Administrator, the Collateral Manager,
          the Servicer and the Special Servicer or any of their respective agents, from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the

      (b)          The Notes shall be issuable in minimum

      Section 2.4        Execution, Authentication, Delivery and Dating.

      

      

      The Notes shall be executed on behalf of the Issuer and, in the case of the Offered Notes, the Co-Issuer by an Authorized Officer of
          the Issuer and, in the case of the Offered Notes, the Co-Issuer, respectively.  The signature of such Authorized Officers on the Notes may be manual or facsimile.

      

      

      
        -53-

        
          


      

      Notes bearing the manual or facsimile signatures of individuals who were at any time the Authorized Officers of the Issuer and, in the
          case of the Offered Notes, the Co-Issuer shall bind the Issuer or the Co-Issuer, as the case may be, notwithstanding the fact that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such
          Notes or did not hold such offices at the date of issuance of such Notes.

      

      

      At any time and from time to time after the execution and delivery of this Indenture, the Issuer and, in the case of the Offered
          Notes, the Co-Issuer may deliver Notes executed by the Issuer and, in the case of the Offered Notes, the Co-Issuer to the Authenticating Agent for authentication and the Authenticating Agent, upon Issuer Order, shall authenticate and deliver such
          Notes as provided in this Indenture and not otherwise.

      

      

      Each Note authenticated and delivered by the Authenticating Agent upon Issuer Order on the Closing Date shall be dated as of the
          Closing Date.  All other Notes that are authenticated after the Closing Date for any other purpose under this Indenture shall be dated the date of their authentication.

      

      

      Notes issued upon transfer, exchange or replacement of other Notes shall be issued in authorized denominations reflecting the original
          aggregate principal amount of the Notes so transferred, exchanged or replaced, but shall represent only the current outstanding principal amount of the Notes so transferred, exchanged or replaced.  In the event that any Note is divided into more
          than one Note in accordance with this Article 2, the original principal amount of such Note shall be proportionately divided among the Notes delivered in exchange
          therefor and shall be deemed to be the original aggregate principal amount of such subsequently issued Notes.

      

      

      No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such
          Note a Certificate of Authentication, substantially in the form provided for herein, executed by the Note Administrator or by the Authenticating Agent by the manual signature of one of their Authorized Officers, and such certificate upon any Note
          shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder.

      

      

      Section 2.5        Registration, Registration of Transfer and Exchange.

      

      

      (a)          The Issuer and the Co-Issuer shall cause to be kept
          a register (the “Notes Register”) in which, subject to such reasonable regulations as it may prescribe, the Issuer and the Co-Issuer shall provide for the registration
          of Notes and the registration of transfers and exchanges of Notes.  The Note Administrator is hereby initially appointed “Notes Registrar” for the purpose of maintaining the Notes Registrar and registering Notes and transfers and exchanges of
          such Notes with respect to the Notes Register kept in the United States as herein provided.  Upon any resignation or removal of the Notes Registrar, the Issuer and the Co-Issuer shall promptly appoint a successor or, in the absence of such
          appointment, assume the duties of Notes Registrar.

      

      

      
        -54-

        
          


      

      The name and address of each Noteholder and the principal amounts and stated interest of each such Noteholder in its Notes shall be
          recorded by the Notes Registrar in the Notes Register.  For the avoidance of doubt, the Notes Register is intended to be and shall be maintained so as to cause the Notes to be considered issued in registered form under Treasury Regulations
          section 5f.103-1(c).

      

      

      If a Person other than the Note Administrator is appointed by the Issuer and the Co-Issuer as Notes Registrar, the Issuer and the
          Co-Issuer shall give the Note Administrator prompt written notice of the appointment of a successor Notes Registrar and of the location, and any change in the location, of the Notes Register, and the Note Administrator shall have the right to
          inspect the Notes Register at all reasonable times and to obtain copies thereof and the Note Administrator shall have the right to rely upon a certificate executed on behalf of the Notes Registrar by an Authorized Officer thereof as to the names
          and addresses of the Holders of the Notes and the principal amounts and numbers of such Notes.  In addition, the Note Registrar shall be required, within one Business Day of each Record Date, to provide the Note Administrator with a copy of the
          Note Registrar in the format required by, and with all accompanying information regarding the Noteholders as may reasonably be required by the Note Administrator.

      

      

      Subject to this Section 2.5, upon surrender for
          registration of transfer of any Notes at the office or agency of the Issuer to be maintained as provided in Section 7.2, the Issuer and the Co-Issuer shall execute, and
          the Authenticating Agent shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination and of a like aggregate principal amount.

      

      

      At the option of the Holder, Notes may be exchanged for Notes of like terms, in any authorized denominations and of like aggregate
          principal amount, upon surrender of the Notes to be exchanged at the office or agency of the Issuer to be maintained as provided in Section 7.2.  Whenever any Note is
          surrendered for exchange, the Issuer and, in the case of the Offered Notes, the Co-Issuer shall execute, and the Authenticating Agent shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive.

      

      

      All Notes issued and authenticated upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer
          and, in the case of the Offered Notes, the Co-Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

      

      

      Every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written
          instrument of transfer in form satisfactory to the Issuer and, in the case of the Offered Notes, the Co‐Issuer and, in each case, the Notes Registrar duly executed by the Holder thereof or his attorney duly authorized in writing.

      

      

      No service charge shall be made to a Holder for any registration of transfer or exchange of Notes, but the Note Administrator may
          require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

      

      

      None of the Notes Registrar, the Issuer or the Co-Issuer shall be required (i) to issue, register the transfer of or exchange any Note
          during a period beginning at the opening of business 15 days before any selection of Notes to be redeemed and ending at the close of business on the day of the mailing of the relevant notice of redemption, or (ii) to register the transfer of or
          exchange any Note so selected for redemption.

      

      

      
        -55-

        
          


      

      (b)         No Note may be sold or transferred (including,
          without limitation, by pledge or hypothecation) unless such sale or transfer is exempt from the registration requirements of the Securities Act and is exempt from the registration requirements under applicable securities laws of any state or
          other jurisdiction.

      

      

      (c)           No Note may be offered, sold, resold or
          delivered, within the United States or to, or for the benefit of, U.S. Persons except in accordance with Section 2.5(e) below and in accordance with Rule 144A to QIBs
          or, solely with respect to Definitive Notes, IAIs who are also Qualified Purchasers purchasing for their own account or for the accounts of one or more QIBs or IAIs who are also Qualified Purchasers, for which the purchaser is acting as fiduciary
          or agent.  The Notes may be offered, sold, resold or delivered, as the case may be, in offshore transactions to non-U.S. Persons in reliance on Regulation S.  None of the Issuer, the Co-Issuer, the Note Administrator, the Trustee or any other
          Person may register the Notes under the Securities Act or the securities laws of any state or other jurisdiction.

      

      

      (d)           Upon final payment due on the Stated Maturity
          Date of a Note, the Holder thereof shall present and surrender such Note at the Corporate Trust Office of the Note Administrator or at the office of the Paying Agent.

      

      

      (e)          Transfers of Global Notes.  Notwithstanding any provision to the contrary herein, so long as a Global Note remains outstanding and is held by or on behalf of the Depository, transfers of a Global Note, in whole or in
          part, shall be made only in accordance with Section 2.2(c) and this Section 2.5(e).

      

      

      (i)            Except as
          otherwise set forth below, transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to nominees of the Depository or to a successor of the Depository or such successor’s nominee.  Transfers of a
          Global Note to a Definitive Note may only be made in accordance with Section 2.10.

      

      

      (ii)         Regulation S Global Note to Rule 144A Global Note or Definitive Note.  If a holder of a beneficial interest in a Regulation S Global Note wishes at any time to
          exchange its interest in such Regulation S Global Note for an interest in the corresponding Rule 144A Global Note or for a Definitive Note or to transfer its interest in such Regulation S Global Note to a Person who wishes to take delivery
          thereof in the form of an interest in the corresponding Rule 144A Global Note or for a Definitive Note, such holder may, subject to the immediately succeeding sentence and the rules and procedures of Euroclear, Clearstream and/or DTC, as the case
          may be, exchange or transfer, or cause the exchange or transfer of, such interest for an equivalent beneficial interest in the corresponding Rule 144A Global Note or for a Definitive Note.  Upon receipt by the Note Administrator or the Notes
          Registrar of:

      

      

      
        -56-

        
          


      

      (1)        if the transferee is taking a
          beneficial interest in a Rule 144A Global Note, instructions from Euroclear, Clearstream and/or DTC, as the case may be, directing the Note Registrar to cause to be credited a beneficial interest in the corresponding Rule 144A Global Note in an
          amount equal to the beneficial interest in such Regulation S Global Note, but not less than the minimum denomination applicable to such holder’s Notes to be exchanged or transferred, such instructions to contain information regarding the
          participant account with DTC to be credited with such increase and a duly completed certificate in the form of Exhibit C-2 attached hereto; or

      

      

      (2)        if the transferee is taking a
          Definitive Note, a duly completed transfer certificate in substantially the form of Exhibit C-3 hereto, certifying that such transferee is an IAI,

      

      

      then the Notes Registrar shall either (x) if the transferee is taking a beneficial interest in a Rule 144A Global
          Note, approve the instructions at DTC to reduce, or cause to be reduced, the Regulation S Global Note by the aggregate principal amount of the beneficial interest in the Regulation S Global Note to be transferred or exchanged and the Notes
          Registrar shall instruct DTC, concurrently with such reduction, to credit or cause to be credited to the securities account of the Person specified in such instructions a beneficial interest in the corresponding Rule 144A Global Note equal to the
          reduction in the principal amount of the Regulation S Global Note or (y) if the transferee is taking an interest in a Definitive Note, the Notes Registrar shall record the transfer in the Notes Register in accordance with Section 2.5(a) and, upon execution by the Issuers, the Authenticating Agent shall authenticate and deliver one or more Definitive Notes, as applicable, registered in the names specified in
          the instructions described above, in principal amounts designated by the transferee (the aggregate of such principal amounts being equal to the aggregate principal amount of the interest in the Regulation S Global Note transferred by the
          transferor).

      

      

      (iii)         Definitive Note or Rule 144A Global Note to Regulation S Global Note.  If a holder of a beneficial interest in a Rule 144A Global Note or a Holder of a Definitive
          Note wishes at any time to exchange its interest in such Rule 144A Global Note or Definitive Note for an interest in the corresponding Regulation S Global Note, or to transfer its interest in such Rule 144A Global Note or Definitive Note to a
          Person who wishes to take delivery thereof in the form of an interest in the corresponding Regulation S Global Note, such holder, provided such holder or, in the case of a transfer, the transferee is not a U.S. person and is acquiring such
          interest in an offshore transaction, may, subject to the immediately succeeding sentence and the rules and procedures of DTC, exchange or transfer, or cause the exchange or transfer of, such interest for an equivalent beneficial interest in the
          corresponding Regulation S Global Note.  Upon receipt by the Note Administrator or the Notes Registrar of:

      

      

      (1)          instructions given in accordance
          with DTC’s procedures from an Agent Member directing the Note Administrator or the Notes Registrar to credit or cause to be credited a beneficial interest in the corresponding Regulation S Global Note, but not less than the minimum denomination
          applicable to such holder’s Notes, in an amount equal to the beneficial interest in the Rule 144A Global Note or Definitive Note to be exchanged or transferred, and in the case of a transfer of Definitive Notes, such Holder’s Definitive Notes
          properly endorsed for assignment to the transferee,

      

      

      
        -57-

        
          


      

      (2)          a written order given in
          accordance with DTC’s procedures containing information regarding the participant account of DTC and the Euroclear or Clearstream account to be credited with such increase,

      

      

      (3)          in the case of a transfer of
          Definitive Notes, a Holder’s Definitive Note properly endorsed for assignment to the transferee, and

      

      

      (4)          a duly completed certificate in
          the form of Exhibit C-1 attached hereto,

      

      

      then the Note Administrator or the Notes Registrar shall approve the instructions at DTC to reduce the principal
          amount of the Rule 144A Global Note (or, in the case of a transfer of Definitive Notes, the Note Administrator or the Notes Registrar shall cancel such Definitive Notes) and to increase the principal amount of the Regulation S Global Note by the
          aggregate principal amount of the beneficial interest in the Rule 144A Global Note or Definitive Note to be exchanged or transferred, and to credit or cause to be credited to the securities account of the Person specified in such instructions a
          beneficial interest in the corresponding Regulation S Global Note equal to the reduction in the principal amount of the Rule 144A Global Note (or, in the case of a cancellation of Definitive Notes, equal to the principal amount of Definitive
          Notes so cancelled).

      

      

      (iv)         Transfer of Rule 144A Global Notes to Definitive Notes.  If, in accordance with Section


              2.10, a holder of a beneficial interest in a Rule 144A Global Note wishes at any time to exchange its interest in such Rule 144A Global Note for a Definitive Note or to transfer its interest in such Rule 144A Global Note to a
          Person who wishes to take delivery thereof in the form of a Definitive Note in accordance with Section 2.10, such holder may, subject to the immediately
          succeeding sentence and the rules and procedures of DTC, exchange or transfer, or cause the exchange or transfer of, such interest for a Definitive Note.  Upon receipt by the Note Administrator or the Notes Registrar of (A) a duly complete
          certificate substantially in the form of Exhibit C-3 and (B) appropriate instructions from DTC, if required, the Note Administrator or the Notes Registrar
          shall approve the instructions at DTC to reduce, or cause to be reduced, the Rule 144A Global Note by the aggregate principal amount of the beneficial interest in the Rule 144A Global Note to be transferred or exchanged, record the transfer in
          the Notes Register in accordance with Section 2.5(a) and upon execution by the Issuers, the Authenticating Agent shall authenticate and deliver one or more
          Definitive Notes, registered in the names specified in the instructions described in clause (B) above, in principal amounts designated by the transferee (the aggregate of such principal amounts being equal to the aggregate principal amount of the
          interest in the Rule 144A Global Note transferred by the transferor).

      (v)          Transfer of Definitive Notes to Rule 144A Global Notes.  If a holder of a Definitive Note wishes at any time to exchange its interest in such Definitive Note for a
          beneficial interest in a Rule 144A Global Note or to transfer such Definitive Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in a Rule 144A Global Note, such holder may, subject to the immediately
          succeeding sentence and the rules and procedures of DTC, exchange or transfer, or cause the exchange or transfer of, such Definitive Note for beneficial interest in a Rule 144A Global Note (provided that no IAI may hold an interest in a Rule 144A Global Note).  Upon receipt by the Note Administrator or the Notes Registrar of (A) a Holder’s Definitive Note properly endorsed for assignment to the
          transferee; (B) a duly completed certificate substantially in the form of Exhibit C-2 attached hereto; (C) instructions given in accordance with DTC’s
          procedures from an Agent Member to instruct DTC to cause to be credited a beneficial interest in the Rule 144A Global Notes in an amount equal to the Definitive Notes to be transferred or exchanged; and (D) a written order given in accordance
          with DTC’s procedures containing information regarding the participant’s account of DTC to be credited with such increase, the Note Administrator or the Notes Registrar shall cancel such Definitive Note in accordance herewith, record the transfer
          in the Notes Register in accordance with Section 2.5(a) and approve the instructions at DTC, concurrently with such cancellation, to credit or cause to be
          credited to the securities account of the Person specified in such instructions a beneficial interest in the corresponding Rule 144A Global Note equal to the principal amount of the Definitive Note transferred or exchanged.

      

      

      (vi)          Transfers of EHRI.  Transfers of the Preferred Shares and restrictions on the transfer of the EHRI shall be governed by the Preferred Share Paying Agency
          Agreement, and be subject to Section 2.5(n).

      

      

      (vii)        Other Exchanges.  In the event that, pursuant to Section 2.10 hereof, a
          Global Note is exchanged for Definitive Notes, such Notes may be exchanged for one another only in accordance with such procedures as are substantially consistent with the provisions above (including certification requirements intended to ensure
          that such transfers are to a QIB who is also a Qualified Purchaser or are to a non-U.S. Person, or otherwise comply with Rule 144A or Regulation S, as the case may be) and as may be from time to time adopted by the Issuer, the Co-Issuer and the
          Note Administrator.

      

      

      (f)          Removal of Legend.  If Notes are issued upon the transfer, exchange or replacement of Notes bearing the applicable legends set forth in Exhibits A
          and B hereto, and if a request is made to remove such applicable legend on such Notes, the Notes so issued shall bear such applicable legend, or such applicable legend
          shall not be removed, as the case may be, unless there is delivered to the Issuer and the Co-Issuer such satisfactory evidence, which may include an Opinion of Counsel of an attorney at law licensed to practice law in the State of New York (and
          addressed to the Issuer and the Note Administrator), as may be reasonably required by the Issuer and the Co-Issuer, if applicable, to the effect that neither such applicable legend nor the restrictions on transfer set forth therein are required
          to ensure that transfers thereof comply with the provisions of Rule 144A or Regulation S, as applicable, the 1940 Act, ERISA or Section 4975 of the Code.  So long as the Issuer or the Co-Issuer is relying on an exemption under or promulgated
          pursuant to the 1940 Act, the Issuer or the Co-Issuer shall not remove that portion of the legend required to maintain an exemption under or promulgated pursuant to the 1940 Act.  Upon provision of such satisfactory evidence, as confirmed in
          writing by the Issuer and the Co-Issuer, if applicable, to the Note Administrator, the Note Administrator, at the direction of the Issuer and the Co-Issuer, if applicable, shall authenticate and deliver Notes that do not bear such applicable
          legend.

      

      

      
        -59-

        
          


      

      (g)          Each beneficial owner of Regulation S Global Notes
          shall be deemed to make the representations and agreements set forth in Exhibit C-1 hereto.

      

      

      (h)          Each beneficial owner of Rule 144A Global Notes
          shall be deemed to make the representations and agreements set forth in Exhibit C-2 hereto.

      

      

      (i)           Each Holder of Definitive Notes shall make the
          representations and agreements set forth in the certificate attached as Exhibit C-3 hereto.

      

      

      (j)          Any purported transfer of a Note not in accordance
          with Section 2.5(a) shall be null and void and shall not be given effect for any purpose hereunder.

      

      

      (k)          Notwithstanding anything contained in this
          Indenture to the contrary, neither the Note Administrator nor the Notes Registrar (nor any other Transfer Agent) shall be responsible or liable for compliance with applicable federal or state securities laws (including, without limitation, the
          Securities Act or Rule 144A or Regulation S promulgated thereunder), the 1940 Act, ERISA or Section 4975 of the Code (or any applicable regulations thereunder); provided, however, that if a specified transfer certificate or Opinion of Counsel is
          required by the express terms of this Section 2.5 to be delivered to the Note Administrator or Notes Registrar prior to registration of transfer of a Note, the Note
          Administrator and/or Notes Registrar, as applicable, is required to request, as a condition for registering the transfer of the Note, such certificate or Opinion of Counsel and to examine the same to determine whether it conforms on its face to
          the requirements hereof (and the Note Administrator or Notes Registrar, as the case may be, shall promptly notify the party delivering the same if it determines that such certificate or Opinion of Counsel does not so conform).

      

      

      (l)           If the Note Administrator has actual knowledge or
          is notified by the Issuer, the Co-Issuer or the Collateral Manager that (i) a transfer or attempted or purported transfer of any interest in any Note was consummated in compliance with the provisions of this Section 2.5 on the basis of a materially incorrect certification from the transferee or purported transferee, (ii) a transferee failed to deliver to the Note Administrator any certification
          required to be delivered hereunder or (iii) the holder of any interest in a Note is in breach of any representation or agreement set forth in any certification or any deemed representation or agreement of such holder, the Note Administrator shall
          not register such attempted or purported transfer and if a transfer has been registered, such transfer shall be absolutely null and void ab initio and
          shall vest no rights in the purported transferee (such purported transferee, a “Disqualified Transferee”) and the last preceding holder of such interest in such Note
          that was not a Disqualified Transferee shall be restored to all rights as a Holder thereof retroactively to the date of transfer of such Note by such Holder.

      

      

      In addition, the Note Administrator may require that the interest in the Note referred to in (i), (ii) or (iii) in the preceding
          paragraph be transferred to any Person designated by the Issuer or the Collateral Manager at a price determined by the Issuer or the Collateral Manager, based upon its estimation of the prevailing price of such interest and each Holder, by
          acceptance of an interest in a Note, authorizes the Note Administrator to take such action.  In any case, none of the Issuer, the Collateral Manager or the Note Administrator shall be held responsible for any losses that may be incurred as a
          result of any required transfer under this Section 2.5(l).

      

      

      
        -60-

        
          


      

      (m)         Each Holder of Notes approves and consents to (i)
          the purchase of the Collateral Interests by the Issuer from the Seller on the Closing Date and (ii) any other transactions between the Issuer, the Collateral Manager and the Seller or its Affiliates that are permitted under the terms of this
          Indenture or the Collateral Interest Purchase Agreement.

      

      

      (n)         As long as any Note is Outstanding, Retained
          Securities and ordinary shares of the Issuer held by Retention Holder or any other disregarded entity of KREF Sub-REIT for U.S. federal income tax purposes may not be transferred, pledged or hypothecated to any Person (except to an affiliate that
          is wholly-owned by KREF Sub-REIT and is disregarded for U.S. federal income tax purposes) unless the Issuer receives a No Entity-Level Tax Opinion with respect to such transfer, pledge or hypothecation (or has previously received No Trade or
          Business Opinion).

      

      

      For the avoidance of doubt, the Indenture Accounts (including income, if any, earned on the investments of funds in such account) will
          be owned by KREF Sub-REIT, if the Issuer is wholly-owned by KREF Sub-REIT, or a subsequent REIT that wholly owns the Issuer, for U.S. federal income tax purposes.  The Issuer shall provide to the Note Administrator (i) an IRS Form W-9 or
          appropriate IRS Form W-8 no later than the Closing Date, and (ii) any additional IRS forms (or updated versions of any previously submitted IRS forms) or other documentation at such time or times required by applicable law or upon the reasonable
          request of the Note Administrator as may be necessary (i) to reduce or eliminate the imposition of U.S. withholding taxes and (ii) to permit the Note Administrator to fulfill its tax reporting obligations under applicable law with respect to the
          Indenture Accounts or any amounts paid to the Issuer.  If any IRS form or other documentation previously delivered becomes obsolete or inaccurate in any respect, Issuer shall timely provide to the Note Administrator accurately updated and
          complete versions of such IRS forms or other documentation.  The Note Administrator shall have no liability to Issuer or any other person in connection with any tax withholding amounts paid or withheld from the Indenture Accounts pursuant to
          applicable law arising from the Issuer’s failure to timely provide an accurate, correct and complete IRS Form W-9, an appropriate IRS Form W-8 or such other documentation contemplated under this paragraph.  For the avoidance of doubt, no funds
          shall be invested with respect to such Indenture Accounts absent the Note Administrator having first received (i) the requisite written investment direction from the Issuer with respect to the investment of such funds, and (ii) the IRS forms and
          other documentation required by this paragraph.

      

      

      Section 2.6        Mutilated, Defaced, Destroyed, Lost or Stolen Note.

      

      

      If (a) any mutilated or defaced Note is surrendered to a Transfer Agent, or if there shall be delivered to the Issuer, the Co-Issuer,
          the Trustee, the Note Administrator and the relevant Transfer Agent (each a “Specified Person”) evidence to their reasonable satisfaction of the destruction, loss or
          theft of any Note, and (b) there is delivered to each Specified Person such security or indemnity as may be required by each Specified Person to save each of them and any agent of any of them harmless, then, in the absence of notice to the
          Specified Persons that such Note has been acquired by a bona fide purchaser, the Issuer and the Co-Issuer shall execute and, upon Issuer Request, the Note Administrator shall cause the Authenticating Agent to authenticate and deliver, in lieu of
          any such mutilated, defaced, destroyed, lost or stolen Note, a new Note, of like tenor (including the same date of issuance) and equal principal amount, registered in the same manner, dated the date of its authentication, bearing interest from
          the date to which interest has been paid on the mutilated, defaced, destroyed, lost or stolen Note and bearing a number not contemporaneously outstanding.

      

      

      
        -61-

        
          


      

      If, after delivery of such new Note, a bona fide purchaser of the predecessor Note presents for payment, transfer or exchange such
          predecessor Note, any Specified Person shall be entitled to recover such new Note from the Person to whom it was delivered or any Person taking therefrom, and each Specified Person shall be entitled to recover upon the security or indemnity
          provided therefor to the extent of any loss, damage, cost or expense incurred by such Specified Person in connection therewith.

      

      

      In case any such mutilated, defaced, destroyed, lost or stolen Note has become due and payable, the Issuer and the Co-Issuer, if
          applicable, in their discretion may, instead of issuing a new Note, pay such Note without requiring surrender thereof except that any mutilated or defaced Note shall be surrendered.

      

      

      Upon the issuance of any new Note under this Section 2.6,
          the Issuer and the Co-Issuer, if applicable, may require the payment by the registered Holder thereof 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.

      

      

      Every new Note issued pursuant to this Section 2.6 in
          lieu of any mutilated, defaced, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer and the Co-Issuer, if applicable, and such new Note shall be entitled, subject to the second paragraph of
          this Section 2.6, to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

      

      

      The provisions of this Section 2.6 are exclusive and
          shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, defaced, destroyed, lost or stolen Notes.

      

      

      Section 2.7        Payment of Principal and Interest and Other Amounts; Principal and Interest Rights Preserved.

      

      

      
        -62-

        
          


      

      (a)           Each Class of Notes shall accrue interest during
          each Interest Accrual Period at the Note Interest Rate applicable to such Class and such interest will be payable in arrears on each Payment Date on the Aggregate Outstanding Amount thereof on the first day of the related Interest Accrual Period
          (after giving effect to payments of principal thereof on such date), except as otherwise set forth below.  Notwithstanding the foregoing, in the event that the Notes convert to the
            Substitute Index, each Class of Notes shall accrue interest during each Interest Accrual Period at the Substitute Index plus the Substitute Index Spread Adjustment applicable to such Class, respectively.  Payment of interest on each Class of Notes will be subordinated to the payment of interest on each related Class of Notes senior thereto.  Any payment of interest due on a Class of Deferred Interest Notes on any
            Payment Date to the extent sufficient funds are not available to make such payment in accordance with the Priority of Payments on such Payment Date, but only if such Class is not the most senior Class Outstanding, shall constitute “Deferred Interest” with
            respect to such Class and shall not be considered “due and payable” for the purposes of Section 5.1(a) (and the failure to pay such interest shall not be an Event of Default) until the earliest of (i) the Payment Date on which funds are available to pay such Deferred Interest in accordance with the Priority of Payments, (ii) the
            Redemption Date with respect to such Class of Deferred Interest Notes and (iii) the Stated Maturity Date (or the earlier date of Maturity) of such Class of Deferred Interest
            Notes.  Deferred Interest on any Class of Deferred Interest Notes shall be added to the principal balance of such Class of Deferred Interest Notes.  Regardless of whether any more senior Class of Notes is Outstanding with respect to any Class
            of Deferred Interest Notes, to the extent that funds are not available on any Payment Date (other than the Redemption Date with respect to, or Stated Maturity Date of, such
            Class of Deferred Interest Notes) to pay previously accrued Deferred Interest, such previously accrued Deferred Interest will not be due and payable on such Payment Date and any failure to pay such previously accrued Deferred Interest on such
            Payment Date will not be an Event of Default. Interest will cease to accrue on each Note, or in the case of a partial repayment, on such repaid part, from the date of repayment or Stated Maturity Date unless payment of principal is improperly withheld or unless an Event of Default occurs with respect to such payments of principal.  To the extent lawful and enforceable, interest on any interest that is not paid
            when due on the Class A Notes; or, if no Class A Notes are Outstanding, the Notes of the Controlling Class, shall accrue at the Note Interest Rate applicable to such Class until paid as provided herein.

      

      

      (b)           The principal of each Class of Notes matures at
          par and is due and payable on the date of the Stated Maturity  Date for such Class, unless such principal has been previously repaid or unless the unpaid principal of such Note becomes due and payable at an earlier date by declaration of
          acceleration, call for redemption or otherwise.  Notwithstanding the foregoing, the payment of principal of each Class of Notes may only occur (other than amounts constituting Deferred Interest thereon which will be payable from Interest
          Proceeds) pursuant to the Priority of Payments.  The payment of principal on any Note (x) may only occur after each Class more senior thereto is no longer Outstanding and (y) is subordinated to the payment on each Payment Date of the principal
          due and payable on each Class more senior thereto and certain other amounts in accordance with the Priority of Payments.  Payments of principal on any Class of Notes that are not paid, in accordance with the Priority of Payments, on any Payment
          Date (other than the Payment Date which is the Stated Maturity Date (or the earlier date of Maturity) of such Class of Notes or any Redemption Date), because of insufficient funds therefor shall not be considered “due and payable” for purposes of
          Section 5.1(a) until the Payment Date on which such principal may be paid in accordance with the Priority of Payments or all Classes of Notes most senior thereto with
          respect to such Class have been paid in full.  Payments of principal of the Notes in connection with a Clean-up Call, Tax Redemption or Optional Redemption will be made in accordance with Section 9.1 and the Priority of Payments.

       

        

    

    
      -63-

      
        


    

    
      
        (c)          As a condition to the
            payment of principal of and interest on any Note without the imposition of U.S. withholding tax, the Issuer shall require certification acceptable to it to enable the Issuer, the Co-Issuer, the Trustee, the Preferred Share Paying Agent and the
            Paying Agent to determine their duties and liabilities with respect to any taxes or other charges that they may be required to deduct or withhold from payments in respect of such Security under any present or future law or regulation of the
            United States or the Cayman Islands or any present or future law or regulation of any political subdivision thereof or taxing authority therein or to comply with any reporting or other requirements under any such law or regulation.  Such
            certification may include U.S. federal income tax forms, such as IRS Form W‐8BEN (Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals)), IRS Form W-8BEN-E (Certificate of Foreign Status
            of Beneficial Owner for United States Tax Withholding and Reporting (Entities), IRS Form W‐8IMY (Certificate of Foreign Intermediary, Foreign Flow-Through Entity or Certain U.S. Branches for United States Tax Withholding and Reporting), IRS
            Form W‐9 (Request for Taxpayer Identification Number and Certification), or IRS Form W‐8ECI (Certificate of Foreign Person’s Claim that Income Is Effectively Connected with the Conduct of a Trade or Business in the United States) or any
            successors to such IRS forms).  In addition, each of the Issuer, Co-Issuer, the Trustee, Preferred Share Paying Agent or any Paying Agent may require certification acceptable to it to enable the Issuer to qualify for a reduced rate of
            withholding in any jurisdiction from or through which the Issuer receives payments on its Collateral.  Each Holder and each beneficial owner of Notes agree to provide any certification requested pursuant to this Section 2.7(f) and to update or replace such form or certification in accordance with its terms or its subsequent amendments.  Furthermore, the Issuer shall require information to
            comply with FATCA requirements pursuant to clause (xii) of the representations and warranties set forth under the third paragraph of Exhibit C‐1 hereto, as
            deemed made pursuant to Section 2.5(g) hereto, or pursuant to clause (xiii) of the representations and warranties set forth under the third paragraph of Exhibit C‐2 hereto, as deemed made pursuant to Section 2.5(h) hereto, or
            pursuant to clause (vii) of the representations and warranties set forth under the third paragraph of Exhibit C-3 hereto, made pursuant to Section 2.5(i) hereto, as applicable.

         

        (d)          Payments in respect of interest on and principal
            of the Notes shall be payable by wire transfer in immediately available funds to a Dollar account maintained by the Holder or its nominee; provided that the Holder
            has provided wiring instructions to the Paying Agent on or before the related Record Date or, if wire transfer cannot be effected, by a Dollar check drawn on a bank in the United States, or by a Dollar check mailed to the Holder at its address
            in the Notes Register.  The Issuer expects that the Depository or its nominee, upon receipt of any payment of principal or interest in respect of a Global Note held by the Depository or its nominee, shall immediately credit the applicable Agent
            Members’ accounts with payments in amounts proportionate to the respective beneficial interests in such Global Note as shown on the records of the Depository or its nominee.  The Issuer also expects that payments by Agent Members to owners of
            beneficial interests in such Global Note held through Agent Members will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for
            such customers.  Such payments will be the responsibility of the Agent Members.  Upon final payment due on the Maturity of a Note, the Holder thereof shall present and surrender such Note at the Corporate Trust Office of the Note Administrator
            or at the office of the Paying Agent (or, to a foreign paying agent appointed by the Note Administrator outside of the United States if then required by applicable law, in the case of a Definitive Note issued in exchange for a beneficial
            interest in the Regulation S Global Note) on or prior to such Maturity.  None of the Issuer, the Co-Issuer, the Trustee, the Note Administrator or the Paying Agent will have any responsibility or liability with respect to any records maintained
            by the Holder of any Note with respect to the beneficial holders thereof or payments made thereby on account of beneficial interests held therein.  In the case where any final payment of principal and interest is to be made on any Note (other
            than on the Stated Maturity Date thereof) the Issuer or, upon Issuer Request, the Note Administrator, in the name and at the expense of the Issuer, shall not more than thirty (30) nor fewer than five (5) Business Days prior to the date on which
            such payment is to be made, mail to the Persons entitled thereto at their addresses appearing on the Notes Register, a notice which shall state the date on which such payment will be made and the amount of such payment and shall specify the
            place where such Notes may be presented and surrendered for such payment.

         

          

        
          -64-

          
            


        

        (e)           Subject to the provisions of Sections 2.7(a) and Section 2.7(d) hereof, Holders of Notes as of the Record Date in respect
            of a Payment Date shall be entitled to the interest accrued and payable in accordance with the Priority of Payments and principal payable in accordance with the Priority of Payments on such Payment Date.  All such payments that are mailed or
            wired and returned to the Paying Agent shall be held for payment as herein provided at the office or agency of the Issuer and the Co-Issuer to be maintained as provided in Section


                7.2 (or returned to the Trustee).

         

        (f)           Interest on any Note which is payable, and is
            punctually paid or duly provided for, on any Payment Date shall be paid to the Person in whose name that Note (or one or more predecessor Notes) is registered at the close of business on the Record Date for such interest.

         

        (g)          Payments of principal to Holders of the Notes of
            each Class shall be made in the proportion that the Aggregate Outstanding Amount of the Notes of such Class registered in the name of each such Holder on such Record Date bears to the Aggregate Outstanding Amount of all Notes of such Class on
            such Record Date.

         

        (h)          Interest accrued with respect to the Notes shall
            be calculated as described in the applicable form of Note attached hereto.

         

        (i)           All reductions in the principal amount of a
            Note (or one or more predecessor Notes) effected by payments of installments of principal made on any Payment Date, Redemption Date or upon Maturity shall be binding upon all future Holders of such Note and of any Note issued upon the
            registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not such payment is noted on such Note.

         

        (j)           Notwithstanding anything contained in this
            Indenture to the contrary, the obligations of the Issuer under the Notes and the Co-Issuer under the Offered Notes, this Indenture and the other Transaction Documents are limited-recourse obligations of the Issuer and non-recourse obligations
            of the Co-Issuer and are payable solely from the Collateral and following realization of the Collateral, all obligations of the Co-Issuers and any claims of the Noteholders, the Trustee or any other parties to any Transaction Documents shall be
            extinguished and shall not thereafter revive.  No recourse shall be had for the payment of any amount owing in respect of the Notes against any Officer, director, employee, shareholder, limited partner or incorporator of the Issuer, the
            Co-Issuer or any of their respective successors or assigns for any amounts payable under the Notes or this Indenture.  It is understood that the foregoing provisions of this paragraph shall not (i) prevent recourse to the Collateral for the
            sums due or to become due under any security, instrument or agreement which is part of the Collateral or (ii) constitute a waiver, release or discharge of any indebtedness or obligation evidenced by the Notes or secured by this Indenture (to
            the extent it relates to the obligation to make payments on the Notes) until such Collateral have been realized, whereupon any outstanding indebtedness or obligation in respect of the Notes, this Indenture and the other Transaction Documents
            shall be extinguished and shall not thereafter revive.  It is further understood that the foregoing provisions of this paragraph shall not limit the right of any Person to name the Issuer or the Co-Issuer as a party defendant in any Proceeding
            or in the exercise of any other remedy under the Notes or this Indenture, so long as no judgment in the nature of a deficiency judgment or seeking personal liability shall be asked for or (if obtained) enforced against any such Person or
            entity.

        (k)          Subject to the foregoing provisions of this Section 2.7, each Note delivered under this Indenture and upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights of unpaid
            interest and principal that were carried by such other Note.

         

        (l)            Notwithstanding any of the foregoing
            provisions with respect to payments of principal of and interest on the Notes (but subject to Sections 2.7(e) and (h)), if the Notes have become or been declared due and payable following an Event of Default and such acceleration of Maturity and its consequences have not been rescinded and annulled and the provisions of Section 5.5 are not applicable, then payments of principal of and interest on such Notes shall be made in accordance with Section 5.7 hereof.

         

        (m)          Payments in respect of the Preferred Shares as
            contemplated by Sections 11.1(a)(i)(19), 11.1(a)(ii)(16) and 11.1(a)(iii)(17) shall be made by the Paying Agent to the Preferred Share Paying Agent.

        The Issuer, the Co-Issuer, the Trustee, the Note Administrator, the Collateral Manager, the Servicer, the Special Servicer and any of
          their respective agents may treat as the owner of a Note the Person in whose name such Note is registered on the Notes Register on the applicable Record Date for the purpose of receiving payments of principal of and interest and other amounts on
          such Note and on any other date for all other purposes whatsoever (whether or not such Note is overdue), and none of the Note Administrator, the Collateral Manager, the Servicer, the Special Servicer or any of their respective agents shall be
          affected by notice to the contrary; provided, however, that the Depository, or its nominee, shall be deemed the owner of the Global Notes, and owners of beneficial interests in Global Notes will not be
          considered the owners of any Notes for the purpose of receiving notices.  With respect to the Preferred Shares, on any Payment Date, the Trustee shall deliver to the Preferred Share Paying Agent the distributions thereon for distribution to the
          Preferred Shareholders.

         

        Section 2.9          Cancellation.

         

        All Notes surrendered for payment, registration of transfer, exchange or redemption, or deemed lost or stolen, shall, upon delivery
            to the Notes Registrar, be promptly canceled by the Notes Registrar and may not be reissued or resold.  No Notes shall be authenticated in lieu of or in exchange for any Notes canceled as provided in this Section 2.9, except as expressly permitted by this Indenture.  All canceled Notes held by the Notes Registrar shall be destroyed or held by the Notes Registrar in accordance with its standard

        Section 2.10          Global Notes; Definitive Notes; Temporary Notes.

         

        (a)           Definitive Notes.  Definitive Notes shall only be issued in the following limited circumstances:

         

        (i) at the discretion of the Issuer, at the direction of the Collateral Manager, with respect to any Class of Notes,

         

          

        (ii)           upon Transfer of Global
            Notes to an IAI in accordance with the procedures set forth in Section 2.5(e)(ii) or Section 2.5(e)(iii);

         

        (iii)         if a
            holder of a Definitive Note wishes at any time to exchange such Definitive Note for one or more Definitive Notes or transfer such Definitive Note to a transferee who wishes to take delivery thereof in the form of a Definitive Note in accordance
            with this Section 2.10, such holder may effect such exchange or transfer upon receipt by the Notes Registrar of (A) a Holder’s Definitive Note properly
            endorsed for assignment to the transferee, and (B) duly completed certificates in the form of Exhibit C-3, upon receipt of which the Notes Registrar shall
            then cancel such Definitive Note in accordance herewith, record the transfer in the Notes Register in accordance with Section 2.5(a) and upon execution by
            the Co-Issuers, the Authenticating Agent shall authenticate and deliver one or more Definitive Notes bearing the same designation as the Definitive Note endorsed for transfer, registered in the names specified in the assignment described in
            clause (A) above, in principal amounts designated by the transferee (the aggregate of such principal amounts being equal to the aggregate principal amount of the Definitive Note surrendered by the transferor);

         

          

        (iv)         in the
            event that the Depository notifies the Issuer and the Co-Issuer that it is unwilling or unable to continue as Depository for a Global Note or if at any time such Depository ceases to be a “Clearing Agency” registered under the Exchange Act and
            a successor depository is not appointed by the Issuer within 90 days of such notice, the Global Notes deposited with the Depository pursuant to Section 2.2
            hereof shall be transferred to the beneficial owners thereof subject to the procedures and conditions set forth in this Section 2.10.

         

        (b)         Any Global Note that is exchanged for a
            Definitive Note shall be surrendered by the Depository to the Notes Administrator’s Corporate Trust Office together with necessary instruction for the registration and delivery of a Definitive Note to the beneficial owners (or such owner’s
            nominee) holding the ownership interests in such Global Note.  Any such transfer shall be made, without charge, and the Authenticating Agent shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal
            aggregate principal amount of Definitive Notes of the same Class and authorized denominations.  Any Definitive Notes delivered in exchange for an interest in a Global Note shall, except as otherwise provided by Section 2.5(f), bear the applicable legend set forth in Exhibits C-1 or C-2, as applicable, and shall be subject to the transfer restrictions referred to in such applicable legend.  The Holder of each such registered individual Global Note may transfer such Global Note by
            surrendering it at the Corporate Trust Office of the Note Administrator, or at the office of the Paying Agent.

        (c)          Subject to the provisions of Section 2.10(b) above, the registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold
            interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

         

        (d)           [Reserved].

         

        (e)           In the event of the occurrence of either of the
            events specified in Section 2.10(a) above, the Issuer and the Co-Issuer shall promptly make available to the Notes Registrar a reasonable supply of Definitive Notes.

         

        Pending the preparation of Definitive Notes pursuant to this Section



                2.10, the Issuer and the Co-Issuer may execute and, upon Issuer Order, the Authenticating Agent shall authenticate and deliver, temporary Notes that are printed, lithographed, typewritten, mimeographed or otherwise reproduced, in
            any authorized denomination, substantially of the tenor of the Definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the Officers executing such Definitive Notes
            may determine, as conclusively evidenced by their execution of such Definitive Notes.

         

        If temporary Definitive Notes are issued, the Issuer and the Co-Issuer shall cause permanent Definitive Notes to be prepared without
            unreasonable delay.  The Definitive Notes shall be printed, lithographed, typewritten or otherwise reproduced, or provided by any combination thereof, or in any other manner permitted by the rules and regulations of any applicable notes
            exchange, all as determined by the Officers executing such Definitive Notes.  After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the applicable temporary Definitive Notes
            at the office or agency maintained by the Issuer and the Co-Issuer for such purpose, without charge to the Holder.  Upon surrender for cancellation of any one or more temporary Definitive Note, the Issuer and the Co-Issuer shall execute, and
            the Authenticating Agent shall authenticate and deliver, in exchange therefor the same aggregate principal amount of Definitive Notes of authorized denominations.  Until so exchanged, the temporary Notes shall in all respects be entitled to the
            same benefits under this Indenture as Definitive Notes.

         

        (f)         Each Holder of a Definitive Note agrees to
            provide the Issuer or its agents with such information and documentation that may be required for the Issuer to comply with the Cayman AML Regulations and shall update or replace such information or documentation as may be necessary.

        Section 2.11        U.S. Tax Treatment of Notes and the Issuer.

         

        (a)           Each of the Issuer and the Co-Issuer intends that, for U.S. federal income tax purposes, (i) the Notes (unless held by KREF Sub-REIT or any entity disregarded into KREF Sub-REIT) be treated as debt, (ii) 100% of
            the Retained Securities and 100% of the ordinary shares of the Issuer be beneficially owned by KREF Sub-REIT, and (iii) the Issuer be treated as a Qualified REIT Subsidiary or other disregarded entity of a REIT for U.S. federal income tax
            purpose (unless, in the case of clause (iii), the Issuer has received a No Trade or Business Opinion).  Each prospective purchaser and any subsequent transferee of a Note or any
              interest therein shall, by virtue of its purchase or other acquisition of such Note or interest therein, be deemed to have agreed to treat such Note in a manner consistent with the preceding sentence for U.S. federal income tax purposes.

         

        (b)           The Issuer and the Co-Issuer shall account for
            the Notes and prepare any reports to Noteholders and tax authorities consistent with the intentions expressed in Section 2.11(a) above.

         

        (c)           Each Holder of Notes shall timely furnish to
            the Issuer and the Co-Issuer or their respective agents any U.S. federal income tax form or certification, such as IRS Form W‐8BEN (Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting
            (Individuals)), IRS Form W-8BEN-E (Certificate of Foreign Status of Beneficial Owner for the United States Tax Withholding and Reporting (Entities)) IRS Form W‐8IMY (Certificate of Foreign Intermediary, Foreign Flow Through Entity, or Certain
            U.S. Branches for United States Tax Withholding and Reporting), IRS Form W‐9 (Request for Taxpayer Identification Number and Certification), or IRS Form W‐8ECI (Certificate of Foreign Person’s Claim that Income is Effectively Connected with the
            Conduct of a Trade or Business in the United States) or any successors to such IRS forms that the Issuer, the Co-Issuer or their respective agents may reasonably request and shall update or replace such forms or certification in accordance with
            its terms or its subsequent amendments.  Furthermore, Noteholders shall timely furnish any information required pursuant to Section 2.7(c).

         

        (d)           The Issuer shall be responsible for all
            calculations of original issue discount on the Notes, if any.

         

        (e)          The Retention Holder, by acceptance of the
            Retained Securities and the ordinary shares of the Issuer, agrees to take no action inconsistent with such treatment and, for so long as any Note is Outstanding, agrees not to sell, transfer, convey, setover, pledge or encumber any Retained
            Securities and/or the ordinary shares of the Issuer, except to the extent permitted pursuant to Section 2.5(n).

         

        Section 2.12        Authenticating Agents.

         

        Upon the request of the Issuer and, in the case of the Offered Notes, the Co-Issuer, the Note Administrator shall, and if the Note
            Administrator so chooses the Note Administrator may, pursuant to this Indenture, appoint one or more Authenticating Agents with power to act on its behalf and subject to its direction in the authentication of Notes in connection with issuance,
            transfers and exchanges under Sections 2.4, 2.5, 2.6 and 8.5 hereof, as fully to all intents and purposes as though each such Authenticating Agent had been expressly
            authorized by such Sections to authenticate such Notes.  For all purposes of this Indenture, the authentication of Notes by an Authenticating Agent pursuant to this Section 2.12
            shall be deemed to be the authentication of Notes by the Note Administrator.

         

          

        
          -69-

          
            


        

        Any corporation or banking association into which any Authenticating Agent may be merged or converted or with which it may be
            consolidated, or any corporation or banking association resulting from any merger, consolidation or conversion to which any Authenticating Agent shall be a party, or any corporation succeeding to the corporate trust business of any
            Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, without the execution or filing of any further act on the part of the parties hereto or such Authenticating Agent or such successor corporation.  Any
            Authenticating Agent may at any time resign by giving written notice of resignation to the Note Administrator, the Trustee, the Issuer and the Co-Issuer.  The Note Administrator may at any time terminate the agency of any Authenticating Agent
            by giving written notice of termination to such Authenticating Agent, the Trustee, the Issuer and the Co-Issuer.  Upon receiving such notice of resignation or upon such a termination, the Note Administrator shall promptly appoint a successor
            Authenticating Agent and shall give written notice of such appointment to the Issuer.

         

        The Note Administrator agrees to pay to each Authenticating Agent appointed by it from time to time reasonable compensation for its
            services, and reimbursement for its reasonable expenses relating thereto and the Note Administrator shall be entitled to be reimbursed for such payments, subject to Section 6.7
            hereof.  The provisions of Sections 2.9, 6.4 and 6.5 hereof shall be applicable to any Authenticating Agent.

         

        Section 2.13        Forced Sale on Failure to Comply with Restrictions.

         

        (a)           Notwithstanding anything to the contrary
            elsewhere in this Indenture, any transfer of a Note or interest therein to a U.S. Person who is determined not to have been both (1) a QIB or an IAI and (2) a Qualified Purchaser at the time of acquisition of the Note or interest therein shall
            be null and void and any such proposed transfer of which the Issuer, the Co-Issuer, the Note Administrator or the Trustee shall have written notice (which includes via electronic mail) may be disregarded by the Issuer, the Co-Issuer, the Note
            Administrator and the Trustee for all purposes.

         

        (b)         If the Issuer determines that any Holder of a
            Note has not satisfied the applicable requirement described in Section 2.13(a) above or such person is a Non-Permitted AML Holder (any such Person a “Non-Permitted Holder”), then the Issuer shall promptly after discovery that such Person is a Non-Permitted Holder by the Issuer, the Co-Issuer or a Responsible Officer of
            the Paying Agent (and notice by the Paying Agent or the Co-Issuer to the Issuer, if either of them makes the discovery), send notice (or cause notice to be sent) to such Non-Permitted Holder demanding that such Non-Permitted Holder transfer its
            interest to a Person that is not a Non-Permitted Holder within 30 days of the date of such notice.  If such Non-Permitted Holder fails to so transfer its Note or interest therein, the Issuer shall have the right, without further notice to the
            Non-Permitted Holder, to sell such Note or interest therein to a purchaser selected by the Issuer that is not a Non-Permitted Holder on such terms as the Issuer may choose.  The Issuer, or a third party acting on behalf of the Issuer, may
            select the purchaser by soliciting one or more bids from one or more brokers or other market professionals that regularly deal in securities similar to the Note, and selling such Note to the highest such bidder.  However, the Issuer may select
            a purchaser by any other means determined by it in its sole discretion.  The Holder of such Note, the Non-Permitted Holder and each other Person in the chain of title from the Holder to the Non-Permitted Holder, by its acceptance of an interest
            in the Note, agrees to cooperate with the Issuer and the Note Administrator to effect such transfers.  The proceeds of such sale, net of any commissions, expenses and taxes due in connection with such sale shall be remitted to the Non-Permitted
            Holder.  The terms and conditions of any sale under this Section 2.13(b) shall be determined in the sole discretion of the Issuer, and the Issuer shall not be liable
            to any Person having an interest in the Note sold as a result of any such sale of exercise of such discretion.

        The Issuer shall not be obligated to pay any additional amounts to the Holders or beneficial owners of the Notes as a result of any
            withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges.

            from the applicable recording office.

         

        (f)           The execution and delivery of this Indenture by
            the Note Administrator shall constitute certification that (i) each original note and/or participation certificate required to be delivered to the Custodian on behalf of the Trustee by the Issuer (or the Seller) and all allonges thereto or
            assignments thereof, if any, have been received by the Custodian; and (ii) such original note or participation certificate has been reviewed by the Custodian and (A) appears regular on its face (handwritten additions, changes or corrections
            shall not constitute irregularities if initialed by the borrower), (B) appears to have been executed and (C) purports to relate to the related Collateral Interest.  The Custodian agrees to review or cause to be reviewed the Collateral Interest
            Files within sixty (60) days after the Closing Date, and to deliver to the Issuer, the Note Administrator, the Servicer, the Collateral Manager and the Trustee a certification in the form of Exhibit D attached hereto, indicating, subject to any exceptions found by it in such review (and any related exception report and any subsequent reports thereto shall be delivered to the other parties hereto and the
            Servicer in electronic format, which shall be Excel-compatible), (A) those documents referred to in Section 3.3(e) that have been received, and (B) that such
            documents have been executed, appear on their face to be what they purport to be, purport to be recorded or filed (as applicable) and have not been torn, mutilated or otherwise defaced, and appear on their faces to relate to the Collateral
            Interest.  The Custodian shall have no responsibility for reviewing the Collateral Interest File except as expressly set forth in this Section 3.3(f).  None of the
            Trustee, the Note Administrator, and the Custodian shall be under any duty or obligation to inspect, review, or examine any such documents, instruments or certificates to independently determine that they are valid, genuine, enforceable,
            legally sufficient, duly authorized, or appropriate for the represented purpose, whether the text of any assignment or endorsement is in proper or recordable form (except to determine if the endorsement conforms to the requirements of Section 3.3(e)), whether any document has been recorded in accordance with the requirements of any applicable jurisdiction, to independently determine that any document
            has actually been filed or recorded in the appropriate office, that any document is other than what it purports to be on its face, or whether the title insurance policies relate to the Mortgaged Property.

            report (which report and any updates or modifications thereto shall be delivered in electronic format, including Excel-compatible format) as to any remaining documents that are required to be, but are not in the Collateral Interest File and
            (ii) request that the Issuer cause such document deficiency to be cured.

            hereunder (including originals of Loan Documents not previously required to be delivered as originals) and as to which the Trustee, Collateral Manager, Servicer or Special Servicer, as applicable, shall have reasonably determined, or shall have
            been advised, to be necessary or appropriate for the administration of such Real Estate Loan hereunder or under the Servicing Agreement or for the protection of the security interest of the Trustee under this Indenture;

         

        (ii)         in
            connection with any delivery of documents to the Custodian pursuant to clause (i) above, the Custodian shall deliver to the Collateral Manager, on behalf of the Issuer, a Certification in the form of Exhibit D acknowledging the receipt of such documents by the Custodian and that it is holding such documents subject to the terms of this Indenture; and

By submission of any such Request for Release, the Servicer or the Special Servicer, as applicable, shall be deemed to have represented and warranted that it has determined in accordance with the Servicing Standard set forth in the Servicing Agreement
              that the requested release is necessary for the administration of such Real Estate Loan hereunder or under the Servicing Agreement or for the protection of the security interest of the Trustee under this Indenture.  The Servicer or the
              Special Servicer shall return to the Custodian each Loan Document released from custody pursuant to this clause (iii) within 20 Business Days of receipt thereof (except such Loan Documents as are released in connection with a sale, exchange
              or other disposition, in each case only as permitted under this Indenture, of the related Collateral Interest that is consummated within such 20-day period).  Notwithstanding the foregoing provisions of this clause (iii), any note,
              participation certificate or other instrument evidencing a Pledged Collateral Interest shall be released only for the purpose of (1) a sale, exchange or other disposition of such Pledged Collateral Interest that is permitted in accordance
              with the terms of this Indenture, (2) presentation, collection, renewal or registration of transfer of such Collateral Interest or (3) in the case of any note, in connection with a payment in full of all amounts owing under such note.

            the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of any action by the Issuer in furtherance of any such action;

         

          

        
          -87-

          
            


        

        (h)         one or more final judgments being rendered
            against the Issuer or the Co-Issuer which exceed, in the aggregate, U.S.$1,000,000 and which remain unstayed, undischarged and unsatisfied for 30 days after such judgment(s) becomes nonappealable, unless adequate funds have been reserved or set
            aside for the payment thereof, and unless (except as otherwise specified in writing by the Rating Agencies) a No Downgrade Confirmation has been received from the Rating Agencies; or

         

        (i)           the Issuer loses its status as a Qualified REIT
            Subsidiary or other disregarded entity of KREF Sub-REIT or any other entity treated as a REIT for U.S. federal income tax purposes, unless (A) within 90 days, the Issuer either (1) delivers an opinion of tax counsel of nationally recognized
            standing in the United States experienced in such matters to the effect that, notwithstanding the Issuer’s loss of Qualified REIT Subsidiary or disregarded entity status for U.S. federal income tax purposes, the Issuer is not, and has not been,
            an association (or publicly traded partnership) taxable as a corporation, or is not, and has not been, otherwise subject to U.S. federal income tax on a net basis and the Noteholders are not otherwise materially adversely affected by the loss
            of Qualified REIT Subsidiary or disregarded entity status for U.S. federal income tax purposes or (2) receives an amount from the Preferred Shareholders sufficient to discharge in full the amounts then due and unpaid on the Notes and amounts
            and expenses described in clauses (1) through (18) under Section 11.1(a)(i) in accordance with the Priority of Payments or (B) all Classes of the Notes are subject to
            a Tax Redemption announced by the Issuer in compliance with this Indenture, and such redemption has not been rescinded.

         

        Upon becoming aware of the occurrence of an Event of Default, the Issuer, shall promptly notify (or shall procure the prompt
            notification of) the Trustee, the Note Administrator, the Servicer, the Special Servicer, the Collateral Manager, the Preferred Share Paying Agent and the Preferred Shareholders in writing.  If the Collateral Manager or Note Administrator has
            actual knowledge of the occurrence of an Event of Default, the Collateral Manager or the Note Administrator shall promptly notify, in writing, the Trustee, the Servicer, the Special Servicer, the Noteholders and the Rating Agencies of the
            occurrence of such Event of Default.

         

        Section 5.2          Acceleration of Maturity; Rescission and Annulment.

         

        (a)           If an Event of Default shall occur and be
            continuing (other than the Events of Default specified in Section 5.1(f) or 5.1(g)), the
            Trustee may (and shall at the direction of a Majority, by outstanding principal amount, of each Class of Notes voting as a separate Class (excluding any Notes owned by the Issuer, the Seller, the Collateral Manager or any of their respective
            Affiliates)), declare the principal of and accrued and unpaid interest on all the Notes to be immediately due and payable (and any such acceleration shall automatically terminate the Reinvestment Period).  Upon any such declaration such
            principal, together with all accrued and unpaid interest thereon, and other amounts payable thereunder in accordance with the Priority of Payments will become immediately due and payable.  If an Event of Default described in Section 5.1(f) or 5.1(g) above occurs, such an acceleration shall occur automatically and
            without any further action, and any such acceleration shall automatically terminate the Reinvestment Period.  If the Notes are accelerated, payments shall be made in the order and priority set forth in Section 11.1(a) hereof.

         

          

        
          -88-

          
            


        

        (b)          At any time after such a declaration of
            acceleration of Maturity of the Notes has been made, and before a judgment or decree for payment of the amounts due has been obtained by the Trustee as hereinafter provided in this Article


                5, a Majority of each Class of Notes (voting as a separate Class), other than with respect to an Event of Default specified in Section 5.1(d), 5.1(f), 5.1(g), or 5.1(i),
            by written notice to the Issuer, the Co-Issuer and the Trustee, may rescind and annul such declaration and its consequences if:

         

        (i)            the Issuer or the
            Co-Issuer has paid or deposited with the Note Administrator a sum sufficient to pay:

         

        (A)        all unpaid
            installments of interest on and principal of the Notes that would be due and payable hereunder if the Event of Default giving rise to such acceleration had not occurred;

         

        (B)        all unpaid
            taxes of the Issuer and the Co-Issuer, Company Administrative Expenses and other sums paid or advanced by or otherwise due and payable to the Note Administrator or to the Trustee hereunder;

         

        (C)        with
            respect to the Advancing Agent and the Backup Advancing Agent, any amount due and payable for unreimbursed Interest Advances and Reimbursement Interest;

         

        (D)       with
            respect to the Collateral Management Agreement, any Collateral Manager Fee then due and any Company Administrative Expense due and payable to the Collateral Manager thereunder; and

         

        (E)          any
            other Company Administrative Expenses then due and payable;

         

        (ii)          the Trustee has received
            notice that all Events of Default, other than the non-payment of the interest on and principal of the Notes that have become due solely by such acceleration, have been cured and a Majority of the Controlling Class, by written notice to the
            Trustee, has agreed with such notice (which agreement shall not be unreasonably withheld or delayed) or waived as provided in Section 5.14.

         

        At any such time that the Trustee, subject to Section 5.2(b),
            shall rescind and annul such declaration and its consequences as permitted hereinabove, the Collateral shall be preserved in accordance with the provisions of Section 5.5
            with respect to the Event of Default that gave rise to such declaration; provided, however, that if such preservation of the Collateral is rescinded pursuant to Section 5.5,
            the Notes may be accelerated pursuant to the first paragraph of this Section 5.2, notwithstanding any previous rescission and annulment of a declaration of
            acceleration pursuant to this paragraph.

         

        No such rescission shall affect any subsequent Default or impair any right consequent thereon.

         

          

        
          -89-

          
            


        

        (c)          Subject to Sections 5.4 and 5.5, a Majority of the Controlling Class shall have the right to direct the Trustee in the conduct
            of any Proceedings for any remedy available to the Trustee or in the sale of any or all of the Collateral; provided that (i) such direction will not conflict with any
            rule of law or this Indenture; (ii) the Trustee may take any other action not inconsistent with such direction; (iii) the Trustee has received security or indemnity satisfactory to it; and (iv) any direction to undertake a sale of the
            Collateral may be made only as described in Section 5.17.  The Trustee shall be entitled to refuse to take any action absent such direction.

         

        (d)          As security for the payment by the Issuer of the
            compensation and expenses of the Trustee, the Note Administrator, and any sums the Trustee or Note Administrator shall be entitled to receive as indemnification by the Issuer, the Issuer hereby grants the Trustee a lien on the Collateral, which
            lien is senior to the lien of the Noteholders.  The Trustee’s lien shall be subject to the Priority of Payments and exercisable by the Trustee only if the Notes have been declared due and payable following an Event of Default and such
            acceleration has not been rescinded or annulled.

         

        (e)           A Majority of the Aggregate Outstanding Amount
            of each Class of Notes may, prior to the time a judgment or decree for the payment of amounts due has been obtained by the Trustee, waive any past Default on behalf of the holders of all the Notes and its consequences in accordance with Section 5.14.

         

        Section 5.3          Collection of Indebtedness and Suits for Enforcement by Trustee.

         

        (a)           The Issuer covenants that if a Default shall
            occur in respect of the payment of any interest and principal on any Class of Notes (but only after any amounts payable pursuant to Section 11.1(a) having a higher
            priority have been paid in full), the Issuer and Co-Issuer shall, upon demand of the Trustee or any affected Noteholder, pay to the Note Administrator on behalf of the Trustee, for the benefit of the Holder of such Note, the whole amount, if
            any, then due and payable on such Note for principal and interest or other payment with interest on the overdue principal and, to the extent that payments of such interest shall be legally enforceable, upon overdue installments of interest, at
            the applicable interest rate and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Note
            Administrator, the Trustee and such Noteholder and their respective agents and counsel.

         

        If the Issuer or the Co-Issuer fails to pay such amounts forthwith upon such demand, the Trustee, as Trustee of an express trust,
            and at the expense of the Issuer, may institute a Proceeding for the collection of the sums so due and unpaid, and may prosecute such Proceeding to judgment or final decree, and may enforce the same against the Issuer and the Co-Issuer or any
            other obligor upon the Notes and collect the amounts adjudged or decreed to be payable in the manner provided by law out of the Collateral.

         

        If an Event of Default occurs and is continuing, the Trustee shall proceed to protect and enforce its rights and the rights of the
            Noteholders by such Proceedings (x) as directed by a Majority of the Controlling Class or (y) in the absence of direction by a Majority of the Controlling Class, as determined by the Trustee acting in good faith; provided, that (a) such direction must not conflict with any rule of law or with any express provision of this Indenture, (b) the Trustee may take any other action deemed proper by the Trustee
            that is not inconsistent with such direction, (c) the Trustee has been provided with security or indemnity satisfactory to it, and (d) notwithstanding the foregoing, any direction to the Trustee to undertake a sale of Collateral may be given
            only in accordance with the preceding paragraph, in connection with any sale and liquidation of all or a portion of the Collateral, the preceding sentence, and, in all cases, the applicable provisions of this Indenture.  Such Proceedings shall
            be used for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy or legal or equitable right vested in the Trustee by this Indenture
            or by law.  Any direction to the Trustee to undertake a Sale of Collateral Interests pursuant to this Article 5 shall be forwarded to the Special Servicer, and the Special Servicer shall conduct any such Sale in accordance with the terms of the
            Servicing Agreement.

         

          

        
          -90-

          
            


        

        In the case where (x) there shall be pending Proceedings relative to the Issuer or the Co-Issuer under the Bankruptcy Code, any
            bankruptcy, insolvency, reorganization or similar law enacted under the laws of the Cayman Islands, or any other applicable bankruptcy, insolvency or other similar law, (y) a receiver, assignee or trustee in bankruptcy or reorganization,
            liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuer or the Co-Issuer, or their respective property, or (z) there shall be any other comparable Proceedings relative to the Issuer or the
            Co-Issuer, or the creditors or property of the Issuer or the Co-Issuer, regardless of whether the principal of any Notes shall then be due and payable as therein expressed or by declaration, or otherwise and regardless of whether the Trustee
            shall have made any demand pursuant to the provisions of this Section 5.3, the Trustee shall be entitled and empowered, by intervention in such Proceedings or
            otherwise:

         

        (i)          to file
            and prove a claim or claims for the whole amount of principal and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee
            (including any claim for reasonable compensation to the Trustee and each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the
            Trustee and each predecessor Trustee, except as a result of negligence or bad faith) and of the Noteholders allowed in any Proceedings relative to the Issuer, the Co-Issuer or other obligor upon the Notes or to the creditors or property of the
            Issuer, the Co-Issuer or such other obligor;

         

        (ii)        unless
            prohibited by applicable law and regulations, to vote on behalf of the Noteholders in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or of a Person
            performing similar functions in comparable Proceedings; and

         

        (iii)        to
            collect and receive (or cause the Note Administrator to collect and receive) any amounts or other property payable to or deliverable on any such claims, and to distribute (or cause the Note Administrator to distribute) all amounts received with
            respect to the claims of the Noteholders and of the Trustee on their behalf; the Secured Parties, and any trustee, receiver or liquidator, custodian or other similar official is hereby authorized by each of the Noteholders to make payments to
            the Trustee (or the Note Administrator on its behalf), and, in the event that the Trustee shall consent to the making of payments directly to the Noteholders, to pay to the Trustee and the Note Administrator such amounts as shall be sufficient
            to cover reasonable compensation to the Trustee and the Note Administrator, each predecessor trustee and note administrator, and their respective agents, attorneys and counsel, and all other reasonable expenses and liabilities incurred, and all
            advances made, by the Backup Advancing Agent and each predecessor backup advancing agent.

         

          

        
          -91-

          
            


        

        Nothing herein contained shall be deemed to authorize the Trustee to authorize, consent to, vote for, accept or adopt, on behalf of
            any Noteholder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Noteholder in any such Proceeding
            except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar Person.

         

        All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without
            the possession of any of the Notes or the production thereof in any trial or other Proceedings relative thereto, and any action or Proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
            recovery of judgment, shall be applied as set forth in Section 5.7.

         

        Notwithstanding anything in this Section 5.3 to the
            contrary, the Trustee may not sell or liquidate the Collateral or institute Proceedings in furtherance thereof pursuant to this Section 5.3 unless the conditions
            specified in Section 5.5(a) are met and any sale of Collateral contemplated to be conducted by the Special Servicer under this Indenture shall be effected by the
            Special Servicer pursuant to the terms of the Servicing Agreement, and the Trustee shall have no liability or responsibility for or in connection with any such sale by the Special Servicer.

         

        Section 5.4          Remedies.

         

        (a)          If an Event of Default has occurred and is
            continuing, and the Notes have been declared due and payable and such declaration and its consequences have not been rescinded and annulled, the Issuer and the Co-Issuer agree that the Trustee, or, with respect to any sale of any Collateral
            Interests, the Special Servicer, may, after notice to the Note Administrator and the Noteholders, and shall, upon direction by a Majority of the Controlling Class, to the extent permitted by applicable law, exercise one or more of the following
            rights, privileges and remedies:

         

        (i)           institute


            Proceedings for the collection of all amounts then payable on the Notes or otherwise payable under this Indenture (whether by declaration or otherwise), enforce any judgment obtained and collect from the Collateral any amounts adjudged due;

         

        (ii)          sell all
            or a portion of the Collateral or rights of interest therein, at one or more public or private sales called and conducted in any manner permitted by law and in accordance with Section 5.17 hereof (provided that any such sale shall be conducted by the Special Servicer pursuant to the Servicing Agreement);

         

          

        
          -92-

          
            


        

        (iii)         institute



            Proceedings from time to time for the complete or partial foreclosure of this Indenture with respect to the Collateral;

         

        (iv)         exercise
            any remedies of a secured party under the UCC and take any other appropriate action to protect and enforce the rights and remedies of the Secured Parties hereunder; and

         

        (v)          exercise
            any other rights and remedies that may be available at law or in equity;

         

        provided, however, that no sale or liquidation of the Collateral or institution of Proceedings in furtherance thereof pursuant to this Section 5.4 may be effected unless either of the conditions specified in Section 5.5(a) are
            met.

         

        The Issuer shall, at the Issuer’s expense, upon request of the Trustee or the Special Servicer, obtain and rely upon an opinion of
            an Independent investment banking firm as to the feasibility of any action proposed to be taken in accordance with this Section 5.4 and as to the sufficiency of the
            proceeds and other amounts expected to be received with respect to the Collateral to make the required payments of principal of and interest on the Notes and other amounts payable hereunder, which opinion shall be conclusive evidence as to such
            feasibility or sufficiency.

         

        (b)           If an Event of Default as described in Section 5.1(e) hereof shall have occurred and be continuing, the Trustee may, and at the request of the Holders of not less than 25% of the Aggregate Outstanding Amount of
            the Controlling Class shall, institute a Proceeding solely to compel performance of the covenant or agreement or to cure the representation or warranty, the breach of which gave rise to the Event of Default under such Section, and enforce any
            equitable decree or order arising from such Proceeding.

         

        (c)           Upon any Sale, whether made under the power of
            sale hereby given or by virtue of judicial proceedings, any Noteholder, Preferred Shareholder, the Collateral Manager or the Servicer or any of their Affiliates may bid for and purchase the Collateral or any part thereof and, upon compliance
            with the terms of Sale, may hold, retain, possess or dispose of such property in its or their own absolute right without accountability; and any purchaser at any such Sale may, in paying the purchase money, turn in any of the Notes in lieu of
            Cash equal to the amount which shall, upon distribution of the net proceeds of such sale, be payable on the Notes so turned in by such Holder (taking into account the Class of such Notes).  Such Notes, in case the amounts so payable thereon
            shall be less than the amount due thereon, shall either be returned to the Holders thereof after proper notation has been made thereon to show partial payment or a new note shall be delivered to the Holders reflecting the reduced interest
            thereon.

         

        Upon any Sale, whether made under the power of sale hereby given or by virtue of judicial proceedings, the receipt of the Note
            Administrator or of the Officer making a sale under judicial proceedings shall be a sufficient discharge to the purchaser or purchasers at any sale for its or their purchase money and such purchaser or purchasers shall not be obliged to see to
            the application thereof.

         

          

        
          -93-

          
            


        

        Any such Sale, whether under any power of sale hereby given or by virtue of judicial proceedings, shall (x) bind the Issuer, the
            Co-Issuer, the Trustee, the Note Administrator, the Noteholders and the Preferred Shareholders, shall operate to divest all right, title and interest whatsoever, either at law or in equity, of each of them in and to the property sold and (y) be
            a perpetual bar, both at law and in equity, against each of them and their successors and assigns, and against any and all Persons claiming through or under them.

         

        (d)        Notwithstanding any other provision of this
            Indenture or any other Transaction Document, none of the Advancing Agent, the Trustee, the Note Administrator or any other Secured Party, any other party to any Transaction Document, the Holder of the Notes and the holders of the equity in the
            Issuer and the Co-Issuer or third party beneficiary of this Indenture may, prior to the date which is one year and one day, or, if longer, the applicable preference period then in effect (including any period established pursuant to the laws of
            the Cayman Islands) after the payment in full of all Notes, institute against, or join any other Person in instituting against, the Issuer, the Co-Issuer or any Permitted Subsidiary any bankruptcy, reorganization, arrangement, insolvency,
            moratorium or liquidation proceedings, or other proceedings under federal or State bankruptcy or similar laws of any jurisdiction.  Nothing in this Section 5.4 shall
            preclude, or be deemed to stop, the Advancing Agent, the Trustee, the Note Administrator, or any other Secured Party or any other party to any Transaction Document (i) from taking any action prior to the expiration of the aforementioned one
            year and one day period, or, if longer, the applicable preference period then in effect (including any period established pursuant to the laws of the Cayman Islands) period in (A) any case or proceeding voluntarily filed or commenced by the
            Issuer or the Co-Issuer or (B) any involuntary insolvency proceeding filed or commenced by a Person other than the Trustee, the Note Administrator or any other Secured Party or any other party to any Transaction Document, or (ii) from
            commencing against the Issuer or the Co-Issuer or any of their respective properties any legal action which is not a bankruptcy, reorganization, arrangement, insolvency, moratorium or liquidation proceeding.

         

        Section 5.5          Preservation of Collateral.

         

        (a)         Notwithstanding anything to the contrary herein,
            if an Event of Default shall have occurred and be continuing when any of the Notes are Outstanding, the Trustee and the Note Administrator, as applicable, shall (except as otherwise expressly permitted or required under this Indenture) retain
            the Collateral securing the Notes, collect and cause the collection of the proceeds thereof and make and apply all payments and deposits and maintain all accounts in respect of the Collateral and the Notes in accordance with the Priority of
            Payments and the provisions of Articles 10, 12 and 13 and shall not sell or liquidate the Collateral, unless either:

         

        (i)          the Note
            Administrator, pursuant to Section 5.5(c), determines that the anticipated proceeds of a sale or liquidation of the Collateral (after deducting the
            reasonable expenses of such sale or liquidation) would be sufficient to discharge in full the amounts then due and unpaid on the Notes, Company Administrative Expenses due and payable pursuant to the Priority of Payments, the Collateral Manager
            Fees due and payable pursuant to the Priority of Payments and amounts due and payable to the Advancing Agent and the Backup Advancing Agent, in respect of unreimbursed Interest Advances and Reimbursement Interest, for principal and interest
            (including accrued and unpaid Deferred Interest), and, upon receipt of information from Persons to whom fees are expenses are payable, all other amounts payable prior to payment of principal of the Notes due and payable pursuant to Section 11.1(a)(iii) and the holders of a Majority of the Controlling Class agrees with such determination; or

         

          

        
          -94-

          
            


        

        (ii)          a
            Supermajority of each Class of Notes (voting as a separate Class) directs the sale and liquidation of all or a portion of the Collateral.

         

        In the event of a sale of a portion of the Collateral pursuant to clause



                (ii) above representing Collateral Interests, the Special Servicer, on behalf of the Trustee, shall sell those items of the Collateral representing Collateral Interests identified by requisite Noteholders pursuant to a written
            direction, received by the Special Servicer, in form and substance satisfactory to the Trustee and all proceeds of such sale shall be remitted to the Note Administrator for distribution in the order set forth in Section 11.1(a).  The Note Administrator shall give written notice of the retention of the Collateral by the Custodian to the Issuer, the Co-Issuer, the Collateral Manager, the Trustee, the
            Servicer, the Special Servicer and the Rating Agencies.  So long as such Event of Default is continuing, any such retention pursuant to this Section 5.5(a) may be
            rescinded at any time when the conditions specified in clause (i) or (ii) above exist.

         

        (b)          Nothing contained in Section 5.5(a) shall be construed to require a sale of the Collateral securing the Notes if the conditions set forth in this Section



                5.5(a) are not satisfied.  Nothing contained in Section 5.5(a) shall be construed to require the Trustee to preserve the Collateral securing the Notes
            if prohibited by applicable law.

         

        (c)           In determining whether the condition specified
            in Section 5.5(a)(i) exists, the Collateral Manager shall obtain bid prices with respect to each Collateral Interest from two dealers (Independent of the Collateral
            Manager and any of its Affiliates) at the time making a market in such Collateral Interests that, at that time, engage in the trading, origination or securitization of loans or participation interests in loans similar to the Collateral
            Interests (or, if only one such dealer can be engaged, then the Collateral Manager shall obtain a bid price from such dealer or, if no such dealer can be engaged, from a pricing service).  The Collateral Manager shall compute the anticipated
            proceeds of sale or liquidation on the basis of the lowest of such bid prices for each such Collateral Interest and provide the Trustee, the Special Servicer and the Note Administrator with the results thereof.  For the purposes of determining
            issues relating to the market value of any Collateral Interest and the execution of a sale or other liquidation thereof, the Special Servicer may, but need not, retain at the expense of the Issuer and rely on an opinion of an Independent
            investment banking firm of national reputation or other appropriate advisors (the cost of which shall be payable as a Company Administrative Expense) in connection with a determination as to whether the condition specified in Section 5.5(a)(i) exists.

         

        The Note Administrator shall promptly deliver to the Noteholders and the Servicer, and the Note Administrator shall post to the Note
            Administrator’s Website, a report stating the results of any determination required to be made pursuant to Section 5.5(a)(i).

         

          

        
          -95-

          
            


        

        Section 5.6         Trustee May Enforce Claims Without Possession of Notes.

         

        All rights of action and claims under this Indenture or under any of the Notes may be prosecuted and enforced by the Trustee without
            the possession of any of the Notes or the production thereof in any trial or other Proceeding relating thereto, and any such action or Proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust.  Any
            recovery of judgment in respect of the Notes shall be applied as set forth in Section 5.7 hereof.

         

        In any Proceedings brought by the Trustee (and in any Proceedings involving the interpretation of any provision of this Indenture to
            which the Trustee shall be a party) in respect of the Notes, the Trustee shall be deemed to represent all the Holders of the Notes.

         

        Section 5.7          Application of Amounts Collected.

         

        Any amounts collected by the Note Administrator with respect to the Notes pursuant to this Article 5 and any amounts that may then be held or thereafter received by the Note Administrator with respect to the Notes hereunder shall be applied subject to Section 13.1 hereof and in accordance with the Priority of Payments set forth in Section 11.1(a)(iii) hereof, at the
            date or dates fixed by the Note Administrator.

         

        Section 5.8          Limitation on Suits.

         

        No Holder of any Notes shall have any right to institute any Proceedings (the right of a Noteholder to institute any proceeding with
            respect to the Indenture or the Notes is subject to any non-petition covenants set forth in the Indenture or the Notes), judicial or otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or trustee, or for
            any other remedy hereunder, unless:

         

        (a)           such Holder has previously given to the Trustee
            written notice of an Event of Default;

         

        (b)          except as otherwise provided in Section 5.9 hereof, the Holders of at least 25% of the then Aggregate Outstanding Amount of the Controlling Class shall have made written request to the Trustee to
            institute Proceedings in respect of such Event of Default in its own name as Trustee hereunder and such Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in
            compliance with such request;

         

        (c)           the Trustee for 30 days after its receipt of
            such notice, request and offer of indemnity has failed to institute any such Proceeding; and

         

        (d)         no direction inconsistent with such written
            request has been given to the Trustee during such 30-day period by a Majority of the Controlling Class; it being understood and intended that no one or more Holders of Notes shall have any right in any manner whatsoever by virtue of, or by
            availing of, any provision of this Indenture or the Notes to affect, disturb or prejudice the rights of any other Holders of Notes of the same Class or to obtain or to seek to obtain priority or preference over any other Holders of the Notes of
            the same Class or to enforce any right under this Indenture or the Notes, except in the manner herein or therein provided and for the equal and ratable benefit of all the Holders of Notes of the same Class subject to and in accordance with Section 13.1 hereof and the Priority of Payments.

         

          

        
          -96-

          
            


        

        In the event the Trustee shall receive conflicting or inconsistent requests and indemnity from two or more groups of Holders of the
            Controlling Class, each representing less than a Majority of the Controlling Class, the Trustee shall not be required to take any action until it shall have received the direction of a Majority of the Controlling Class.

         

        Section 5.9         Unconditional Rights of Noteholders to Receive Principal and Interest.

         

        Notwithstanding any other provision in this Indenture (except for Section



                2.7(d) and 2.7(m)), the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of and
            interest on such Note as such principal, interest and other amounts become due and payable in accordance with the Priority of Payments and Section 13.1, and, subject
            to the provisions of Sections 5.4 and 5.8 to institute Proceedings for the enforcement
            of any such payment, and such right shall not be impaired without the consent of such Holder; provided, however, that the right of such Holder to institute proceedings for the enforcement of any such payment shall not be subject to the
            25% threshold requirement set forth in Section 5.8(b).

         

        Section 5.10       Restoration of Rights and Remedies.

         

        If the Trustee or any Noteholder has instituted any Proceeding to enforce any right or remedy under this Indenture and such
            Proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Noteholder, then (and in every such case) the Issuer, the Co-Issuer, the Trustee, and the Noteholder shall, subject to any
            determination in such Proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Noteholders shall continue as though no such Proceeding had been
            instituted.

         

        Section 5.11       Rights and Remedies Cumulative.

         

        No right or remedy herein conferred upon or reserved to the Trustee, the Note Administrator or to the Noteholders is intended to be
            exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or
            otherwise.  The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

         

        Section 5.12       Delay or Omission Not Waiver.

         

        No delay or omission of the Trustee or of any Noteholder to exercise any right or remedy accruing upon any Event of Default shall
            impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein or a waiver of a subsequent Event of Default.  Every right and remedy given by this Article 5 or by law to the Trustee, or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee, or by the Noteholders, as the case may be.

         

          

        
          -97-

          
            


        

        Section 5.13       Control by the Controlling Class.

         

        Subject to Sections 5.2(a) and (b), but notwithstanding any other provision of this Indenture, if an Event of Default shall have occurred and be continuing when any of the Notes are Outstanding, a
            Majority of the Controlling Class shall have the right to cause the institution of, and direct the time, method and place of conducting, any Proceeding for any remedy available to the Trustee and for exercising any trust, right, remedy or power
            conferred on the Trustee in respect of the Notes; provided that:

         

        (a)           such direction shall not conflict with any rule
            of law or with this Indenture;

         

        (b)           the Trustee may take any other action deemed
            proper by the Trustee that is not inconsistent with such direction; provided, however, that, subject to Section 6.1, the Trustee need not take any action that it
            determines might involve it in liability (unless the Trustee has received indemnity satisfactory to it against such liability as set forth below);

         

        (c)           the Trustee shall have been provided with
            indemnity satisfactory to it; and

         

        (d)          notwithstanding the foregoing, any direction to
            the Trustee to undertake a Sale of the Collateral Interests shall be performed by the Special Servicer on behalf of the Trustee, and must satisfy the requirements of Section 5.5.

         

        Section 5.14        Waiver of Past Defaults.

         

        Prior to the time a judgment or decree for payment of the amounts due has been obtained by the Trustee, as provided in this Article 5, a Majority of each and every Class of Notes (voting as a separate Class) may, on behalf of the Holders of all the Notes, waive any past Default in respect of
            the Notes and its consequences, except a Default:

         

        (a)          in the payment of principal of any Note;

         

        (b)          in the payment of interest in respect of the
            Controlling Class;

         

        (c)           in respect of a covenant or provision hereof
            that, under Section 8.2, cannot be modified or amended without the waiver or consent of the Holder of each Outstanding Note adversely affected thereby; or

         

        (d)           in respect of any right, covenant or provision
            hereof for the individual protection or benefit of the Trustee or the Note Administrator, without the Trustee’s or the Note Administrator’s express written consent thereto, as applicable.

         

        In the case of any such waiver, the Issuer, the Co-Issuer, the Trustee, and the Holders of the Notes shall be restored to their
            respective former positions and rights hereunder, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto.

         

          

        
          -98-

          
            


        

        Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been
            cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto.  Any such waiver shall be effectuated upon receipt by the Trustee and the Note Administrator
            of a written waiver by such Majority of each Class of Notes.

         

        Section 5.15       Undertaking for Costs.

         

        All parties to this Indenture agree, and each Holder of any Note by its 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, 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 5.15 shall not apply to any suit instituted by (x) the Trustee, (y) any
            Noteholder, or group of Noteholders, holding in the aggregate more than 10% of the Aggregate Outstanding Amount of the Controlling Class or (z) any Noteholder for the enforcement of the payment of the principal of or interest on any Note or any
            other amount payable hereunder on or after the Stated Maturity Date (or, in the case of redemption, on or after the applicable Redemption Date).

         

        Section 5.16      Waiver of Stay or Extension Laws.

         

        Each of the Issuer and the Co-Issuer covenants (to the extent that it may lawfully do so) that it will not at any time insist upon,
            plead or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force (including but not limited to filing a voluntary petition under Chapter 11 of the
            Bankruptcy Code and by the voluntary commencement of a proceeding or the filing of a petition seeking winding up, liquidation, reorganization or other relief under any bankruptcy, insolvency, reorganization, moratorium, receivership,
            conservatorship or other similar laws now or hereafter in effect), which may affect the covenants, the performance of or any remedies under this Indenture; and each of the Issuer and the Co-Issuer (to the extent that it may lawfully do so)
            hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as
            though no such law had been enacted.

         

        Section 5.17      Sale of Collateral.

         

        (a)        The power to effect any sale (a “Sale”) of any portion of the Collateral pursuant to Sections 5.4 and 5.5 hereof shall not be exhausted by any one or more Sales as to any portion of such Collateral remaining unsold, but shall continue unimpaired until all amounts secured by the Collateral
            shall have been paid or if there are insufficient proceeds to pay such amount until the entire Collateral shall have been sold.  The Special Servicer may, upon notice to the Securityholders, and shall, upon direction of a Majority of the
            Controlling Class, from time to time postpone any Sale by public announcement made at the time and place of such Sale; provided, however, that if the Sale is rescheduled for a date more than three Business Days after the date of the determination by the Note Administrator pursuant to Section 5.5(a)(i) hereof, such Sale shall not occur unless and until the Note Administrator has again made the determination required by Section 5.5(a)(i) hereof.  The Trustee hereby expressly waives its rights to any amount fixed by law as compensation for any Sale; provided
            that the Special Servicer shall be authorized to deduct the reasonable costs, charges and expenses incurred by it, or by the Trustee or the Note Administrator in connection with such Sale from the proceeds thereof notwithstanding the provisions
            of Section 6.7 hereof.

         

          

        
          -99-

          
            


        

        (b)           The Notes need not be produced in order to
            complete any such Sale, or in order for the net proceeds of such Sale to be credited against amounts owing on the Notes.

         

        (c)           The Trustee shall execute and deliver an
            appropriate instrument of conveyance transferring its interest in any portion of the Collateral in connection with a Sale thereof, which, in the case of any Collateral Interests, shall be upon request and delivery of any such instruments by the
            Special Servicer.  In addition, the Special Servicer, with respect to Collateral Interests, and the Trustee, with respect to any other Collateral, is hereby irrevocably appointed the agent and attorney in fact of the Issuer to transfer and
            convey its interest in any portion of the Collateral in connection with a Sale thereof, and to take all action necessary to effect such Sale.  No purchaser or transferee at such a Sale shall be bound to ascertain the Trustee’s or Special
            Servicer’s authority, to inquire into the satisfaction of any conditions precedent or to see to the application of any amounts.

         

        (d)           In the event of any Sale of the Collateral
            pursuant to Section 5.4 or Section 5.5, payments shall be made in the order and priority
            set forth in Section 11.1(a) in the same manner as if the Notes had been accelerated.

         

        (e)           Notwithstanding anything herein to the
            contrary, any Sale by the Trustee of any portion of the Collateral Interests shall be executed by the Special Servicer on behalf of the Issuer, and the Trustee shall have no responsibility or liability therefor.

         

        Section 5.18        Action on the Notes.

         

        The Trustee’s right to seek and recover judgment on the Notes or under this Indenture shall not be affected by the application for
            or obtaining of any other relief under or with respect to this Indenture.  Neither the lien of this Indenture nor any rights or remedies of the Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Trustee against
            the Issuer or the Co-Issuer or by the levy of any execution under such judgment upon any portion of the Collateral or upon any of the Collateral of the Issuer or the Co-Issuer.

        ARTICLE 6

         

        THE TRUSTEE AND NOTE ADMINISTRATOR

         

        Section 6.1          Certain Duties and Responsibilities.

         

        (a)           Except during the continuance of an Event of
            Default:

         

        (i)          each of
            the Trustee and the Note Administrator undertakes to perform such duties and only such duties as are set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee or the Note
            Administrator; and any permissive right of the Trustee or the Note Administrator contained herein shall not be construed as a duty; and

         

        (ii)         in the
            absence of manifest error, or bad faith on its part, each of the Note Administrator and the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions
            furnished to the Trustee and the Note Administrator, as the case may be, and conforming to the requirements of this Indenture; provided, however, that in the case of any such certificates or
            opinions which by any provision hereof are specifically required to be furnished to the Trustee or the Note Administrator, the Trustee and the Note Administrator shall be under a duty to examine the same to determine whether or not they
            substantially conform to the requirements of this Indenture and shall promptly notify the party delivering the same if such certificate or opinion does not conform.  If a corrected form shall not have been delivered to the Trustee or the Note
            Administrator within 15 days after such notice from the Trustee or the Note Administrator, the Trustee or the Note Administrator, as applicable, shall notify the party providing such instrument and requesting the correction thereof.

         

        (b)          In case an Event of Default actually known to a
            Trust Officer of the Trustee has occurred and is continuing, the Trustee shall, prior to the receipt of directions, if any, from a Majority of the Controlling Class (or other Noteholders to the extent provided in Article 5 hereof), exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under
            the circumstances in the conduct of such Person’s own affairs.

         

        (c)           If, in performing its duties under this
            Indenture, the Trustee or the Note Administrator is required to decide between alternative courses of action, the Trustee and the Note Administrator may request written instructions from the Collateral Manager as to courses of action desired by
            it.  If the Trustee and the Note Administrator does not receive such instructions within two (2) Business Days after it has requested them, it may, but shall be under no duty to, take or refrain from taking such action.  The Trustee and the
            Note Administrator shall act in accordance with instructions received after such two (2) Business Day period except to the extent it has already taken, or committed itself to take, action inconsistent with such instructions.  The Trustee and
            the Note Administrator shall be entitled to request and rely on the advice of legal counsel and Independent accountants in performing its duties hereunder and be deemed to have acted in good faith and shall not be subject to any liability if it
            acts in accordance with such advice.

         

          

        
          -101-

          
            


        

        (d)          No provision of this Indenture shall be
            construed to relieve the Trustee or the Note Administrator from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that neither the Trustee nor the Note Administrator shall be liable:

         

        (i)            for any
            error of judgment made in good faith by a Trust Officer, unless it shall be proven that it was negligent in ascertaining the pertinent facts; or

         

        (ii)         with
            respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Issuer, the Collateral Manager, and/or a Majority of the Controlling Class relating to the time, method and place of conducting any
            Proceeding for any remedy available to the Trustee or the Note Administrator in respect of any Note or exercising any trust or power conferred upon the Trustee or the Note Administrator under this Indenture.

         

        (e)         No provision of this Indenture shall require the
            Trustee or the Note Administrator to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers contemplated hereunder, if it
            shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it unless such risk or liability relates to its ordinary services under this Indenture,
            except where this Indenture provides otherwise.

         

        (f)           Neither the Trustee nor the Note Administrator
            shall be liable to the Noteholders for any action taken or omitted by it at the direction of the Issuer, the Co-Issuer, the Collateral Manager, the Servicer, the Special Servicer, the Controlling Class, the Trustee (in the case of the Note
            Administrator), the Note Administrator (in the case of the Trustee) and/or a Noteholder under circumstances in which such direction is required or permitted by the terms of this Indenture.

         

        (g)           For all purposes under this Indenture, neither
            the Trustee nor the Note Administrator shall be deemed to have notice or knowledge of any Event of Default, unless a Trust Officer of either the Trustee or the Note Administrator, as applicable, has actual knowledge thereof or unless written
            notice of any event which is in fact such an Event of Default or Default is received by the Trustee or the Note Administrator, as applicable at the respective Corporate Trust Office, and such notice references the Notes and this Indenture.  For
            purposes of determining the Trustee’s and Note Administrator’s responsibility and liability hereunder, whenever reference is made in this Indenture to such an Event of Default or a Default, such reference shall be construed to refer only to
            such an Event of Default or Default of which the Trustee or Note Administrator, as applicable, is deemed to have notice as described in this Section 6.1.

         

        (h)           The Trustee and the Note Administrator shall,
            upon reasonable prior written notice, permit the Issuer, the Collateral Manager and their designees, during its normal business hours, to review all books of account, records, reports and other papers of the Trustee relating to the Notes and to
            make copies and extracts therefrom (the reasonable out-of-pocket expenses incurred in making any such copies or extracts to be reimbursed to the Trustee or the Note Administrator, as applicable, by such Person).

            the Trustee or after any declaration of acceleration has been made or delivered to the Trustee pursuant to Section 5.2, the Trustee shall transmit by mail to the
            17g‐5 Information Provider and to the Note Administrator (who shall post such notice the Note Administrator’s Website) and the Note Administrator shall deliver to the Collateral Manager, all Holders of Notes as their names and addresses appear
            on the Notes Register, and to Preferred Share Paying Agent, notice of such Default, unless such Default shall have been cured or waived.

            and without limiting the foregoing, neither the Trustee nor the Note Administrator shall be under any obligation to verify compliance by any party hereto with the terms of this Indenture (other than itself) or to verify or independently
            determine the accuracy of information received by it from the Servicer or Special Servicer (or from any selling institution, agent bank, trustee or similar source) with respect to the Real Estate Loans;

         

        (k)          to the extent any defined term hereunder, or any
            calculation required to be made or determined by the Trustee or Note Administrator hereunder, is dependent upon or defined by reference to generally accepted accounting principles in the United States in effect from time to time (“GAAP”), the Trustee and Note Administrator shall be entitled to request and receive (and rely upon) instruction from the Issuer or the accountants appointed pursuant to Section 10.12 as to the application of GAAP in such connection, in any instance;

        The Trustee, the Note Administrator, the Paying Agent, the Notes Registrar or any other agent of the Issuer or the Co-Issuer, in its
            individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer and the Co-Issuer with the same rights it would have if it were not Trustee, Note Administrator, Paying Agent, Notes Registrar or
            such other agent.

         

        Section 6.6          Amounts Held in Trust.

         

        Amounts held by the Note Administrator hereunder shall be held in trust to the extent required herein.  The Note Administrator shall
            be under no liability for interest on any amounts received by it hereunder except to the extent of income or other gain on investments received by the Note Administrator on Eligible Investments.

         

        Section 6.7          Compensation and Reimbursement.

         

        (a)          The Issuer agrees:

         

        (i)           to pay
            the Trustee and Note Administrator on each Payment Date in accordance with the Priority of Payments reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to
            the compensation of a trustee or note administrator of an express trust);

         

        (ii)          except
            as otherwise expressly provided herein, to reimburse the Trustee and Note Administrator in a timely manner upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee or Note Administrator in
            connection with its performance of its obligations under, or otherwise in accordance with any provision of this Indenture;

         

        (iii)        to
            indemnify the Trustee or Note Administrator and its Officers, directors, employees and agents for, and to hold them harmless against, any loss, liability or expense (including any expenses incurred in connection with the enforcement of this
            indemnity) incurred without negligence, willful misconduct or bad faith on their part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending themselves against any
            claim or liability in connection with the exercise or performance of any of their powers or duties hereunder or under the Servicing Agreement or the Preferred Share Paying Agency; and

         

        (iv)          to pay
            the Trustee and Note Administrator reasonable additional compensation together with its expenses (including reasonable counsel fees) for any collection action taken pursuant to Section 6.13 hereof.

         

        (b)         The Issuer may remit payment for such fees and
            expenses to the Trustee and Note Administrator or, in the absence thereof, the Note Administrator may from time to time deduct payment of its and the Trustee’s fees and expenses hereunder from amounts on deposit in the Payment Account in
            accordance with the Priority of Payments.

         

          

        
          -106-

          
            


        

        (c)           The Note Administrator, in its capacity as Note
            Administrator, Paying Agent, Calculation Agent, Transfer Agent, Custodian, Securities Intermediary, Backup Advancing Agent and Notes Registrar, hereby agrees not to cause the filing of a petition in bankruptcy against the Issuer, the Co-Issuer
            or any Permitted Subsidiary until at least one year and one day (or, if longer, the applicable preference period then in effect) after the payment in full of all Notes issued under this Indenture.  This provision shall survive termination of
            this Indenture.

         

        (d)          The Trustee and Note Administrator agree that
            the payment of all amounts to which it is entitled pursuant to Sections 6.7(a)(i), (a)(ii),
            (a)(iii) and (a)(iv) shall be subject to the Priority of Payments, shall be payable only
            to the extent funds are available in accordance with such Priority of Payments, shall be payable solely from the Collateral and following realization of the Collateral, any such claims of the Trustee or Note Administrator against the Issuer,
            and all obligations of the Issuer, shall be extinguished.  The Trustee and Note Administrator will have a lien upon the Collateral to secure the payment of such payments to it in accordance with the Priority of Payments; provided that the Trustee and Note Administrator shall not institute any proceeding for enforcement of such lien except in connection with an action taken pursuant to Section 5.3 hereof for enforcement of the lien of this Indenture for the benefit of the Noteholders.

         

        The Trustee and Note Administrator shall receive amounts pursuant to this Section 6.7 and Section 11.1(a) only to the extent that such payment is made in accordance with the Priority of Payments and the failure to
            pay such amounts to the Trustee and Note Administrator will not, by itself, constitute an Event of Default.  Subject to Section 6.9, the Trustee and Note
            Administrator shall continue to serve under this Indenture notwithstanding the fact that the Trustee and Note Administrator shall not have received amounts due to it hereunder; provided
            that the Trustee and Note Administrator shall not be required to expend any funds or incur any expenses unless reimbursement therefor is reasonably assured to it.  No direction by a Majority of the Controlling Class shall affect the right of
            the Trustee and Note Administrator to collect amounts owed to it under this Indenture.

         

        If on any Payment Date, an amount payable to the Trustee and Note Administrator pursuant to this Indenture is not paid because there
            are insufficient funds available for the payment thereof, all or any portion of such amount not so paid shall be deferred and payable on any later Payment Date on which sufficient funds are available therefor in accordance with the Priority of
            Payments.

         

        Section 6.8        Corporate Trustee Required; Eligibility.

         

        There shall at all times be a Trustee and a Note Administrator hereunder which (i) shall be a corporation organized and doing
            business under the laws of the United States of America or of any State thereof, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least U.S.$200,000,000, subject to supervision or
            examination by federal or State authority, having a long-term unsecured debt rating of at least “A2” by Moody’s and a rating by KBRA equivalent to at least a “A2” rating by Moody’s; provided, that with respect to the Trustee, it may maintain a
            long-term unsecured debt rating of at least “Baa1” by Moody’s and a rating by KBRA equivalent to at least a “Baa1” rating by Moody’s and a short-term unsecured debt rating of at least “P-2” by Moody’s and a rating by KBRA equivalent to at least
            a “P-2” rating by Moody’s so long as the Servicer maintains a long-term unsecured debt rating of at least “A2” by Moody’s and a rating by KBRA equivalent to at least a “A2” rating by Moody’s (the Servicer shall have no obligation to maintain
            such rating), or such other rating with respect to which the Rating Agencies have provided a No Downgrade Confirmation (provided that this proviso shall not impose on the Servicer any obligation to maintain such rating), and having an office
            within the United States and (ii) with respect to the Trustee, is not an affiliate (as that term is defined under Rule 405 under the Securities Act) of the Issuer or any Person involved in the organization or operation of the Issuer.  If such
            corporation 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 6.8, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

         

          

        
          -107-

          
            


        

        If at any time the Trustee or the Note Administrator shall cease to be eligible in accordance with the provisions of this Section 6.8, the Trustee or the Note Administrator, as applicable, shall resign immediately in the manner and with the effect hereinafter specified in this Article 6.

         

        Section 6.9          Resignation and Removal; Appointment of Successor.

         

        (a)         No resignation or removal of the Note
            Administrator or the Trustee and no appointment of a successor Note Administrator or Trustee, as applicable, pursuant to this Article 6 shall become effective until
            the acceptance of appointment by such successor Note Administrator or Trustee under Section 6.10.

         

        (b)           Each of the Trustee and the Note Administrator
            may resign at any time by giving written notice thereof to the Issuer, the Co-Issuer, the Collateral Manager, the Servicer, the Special Servicer, the Noteholders, the Note Administrator (in the case of the Trustee), the Trustee (in the case of
            the Note Administrator), and the Rating Agencies.  Upon receiving such notice of resignation, the Issuer and the Co-Issuer shall promptly appoint a successor trustee or trustees, or a successor Note Administrator, as the case may be, by written
            instrument, in duplicate, executed by an Authorized Officer of the Issuer and an Authorized Officer of the Co-Issuer, one copy of which shall be delivered to the Note Administrator or the Trustee so resigning and one copy to the successor Note
            Administrator, Trustee or Trustees, together with a copy to each Noteholder, the Servicer, the parties hereto and the Rating Agencies; provided that such successor
            Note Administrator and Trustee shall be appointed only upon the written consent of a Majority of the Notes (or if there are no Notes Outstanding, a Majority of Preferred Shareholders) or, at any time when an Event of Default shall have occurred
            and be continuing or when a successor Note Administrator and Trustee has been appointed pursuant to Section 6.10, by Act of a Majority of the Controlling Class.  If
            no successor Note Administrator and Trustee shall have been appointed and an instrument of acceptance by a successor Trustee or Note Administrator shall not have been delivered to the Trustee or the Note Administrator within 30 days after the
            giving of such notice of resignation, the resigning Trustee or Note Administrator, as the case may be, the Controlling Class of Notes or any Holder of a Note, on behalf of himself and all others similarly situated, may petition any court of
            competent jurisdiction for the appointment of a successor Trustee or a successor Note Administrator, as the case may be, at the expense of the Issuer.  No resignation or removal of the Note Administrator or the Trustee and no appointment of a
            successor Note Administrator or Trustee will become effective until the acceptance of appointment by the successor Note Administrator or Trustee, as applicable.

         

          

        
          -108-

          
            


        

        (c)          The Note Administrator and Trustee may be removed
            at any time by Act of a Supermajority of the Notes, upon not less than 30 days’ written notice (or if there are no Notes Outstanding, a Majority of Preferred Shareholders) or when a successor Trustee has been appointed pursuant to Section 6.10, by Act of a Majority of the Controlling Class, in each case, upon written notice delivered to the parties hereto.

         

        (d)          If at any time:

         

        (i)            the
            Trustee or the Note Administrator shall cease to be eligible under Section 6.8 and shall fail to resign after written request therefor by the Issuer, the
            Co-Issuer, or by any Holder; or

         

        (ii)           the
            Trustee or the Note Administrator shall become incapable of acting or there shall be instituted any proceeding pursuant to which it could be adjudged as bankrupt or insolvent or a receiver or liquidator of the Trustee or the Note Administrator
            or of its respective property shall be appointed or any public officer shall take charge or control of the Trustee or the Note Administrator or of its respective property or affairs for the purpose of rehabilitation, conservation or
            liquidation;

         

        then, in any such case (subject to Section 6.9(a)), (a) the Issuer or the
            Co-Issuer, by Issuer Order, may remove the Trustee or the Note Administrator, as applicable, or (b) subject to Section 5.15, a Majority of the Controlling Class or
            any Holder may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee or the Note Administrator, as the case may be, and the appointment of a successor thereto.

         

        (e)           If the Trustee or the Note Administrator shall
            resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Trustee or the Note Administrator for any reason, the Issuer and the Co-Issuer, by Issuer Order, subject to the written consent of the Collateral
            Manager, shall promptly appoint a successor Trustee or Note Administrator, as applicable, and the successor Trustee or Note Administrator so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee or the
            successor Note Administrator, as the case may be.  If the Issuer and the Co-Issuer shall fail to appoint a successor Trustee or Note Administrator within 30 days after such resignation, removal or incapability or the occurrence of such vacancy,
            a successor Trustee or Note Administrator may be appointed by Act of a Majority of the Controlling Class delivered to the Collateral Manager and the parties hereto, including the retiring Trustee or the retiring Note Administrator, as the case
            may be, and the successor Trustee or Note Administrator so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee or Note Administrator, as applicable, and supersede any successor Trustee or Note
            Administrator proposed by the Issuer and the Co-Issuer.  If no successor Trustee or Note Administrator shall have been so appointed by the Issuer and the Co-Issuer or a Majority of the Controlling Class and shall have accepted appointment in
            the manner hereinafter provided, subject to Section 5.15, the Controlling Class or any Holder may, on behalf of itself or himself and all others similarly situated,
            petition any court of competent jurisdiction for the appointment of a successor Trustee or Note Administrator.

        (f)           The Issuer and the Co-Issuer shall give prompt
            notice of each resignation and each removal of the Trustee or Note Administrator and each appointment of a successor Trustee or Note Administrator by mailing written notice of such event by first class mail, postage prepaid, to the Rating
            Agencies, the Preferred Share Paying Agent, the Collateral Manager, the parties hereto, and to the Holders of the Notes as their names and addresses appear in the Notes Register.  Each notice shall include the name of the successor Trustee or
            Note Administrator, as the case may be, and the address of its respective Corporate Trust Office.  If the Issuer or the Co-Issuer fail to mail such notice within ten days after acceptance of appointment by the successor Trustee or Note
            Administrator, the successor Trustee or Note Administrator shall cause such notice to be given at the expense of the Issuer or the Co-Issuer, as the case may be.

         

        (g)          The resignation or removal of the Note
            Administrator in any capacity in which it is serving hereunder, including Note Administrator, Paying Agent, Authenticating Agent, Calculation Agent, Transfer Agent, Custodian, Securities Intermediary, Backup Advancing Agent and Notes Registrar,
            shall be deemed a resignation or removal, as applicable, in each of the other capacities in which it serves.

         

        Section 6.10        Acceptance of Appointment by Successor.

         

        Every successor Trustee or Note Administrator appointed hereunder shall execute, acknowledge and deliver to the Collateral Manager,
            the Servicer, and the parties hereto including the retiring Trustee or the retiring Note Administrator, as the case may be, an instrument accepting such appointment.  Upon delivery of the required instruments, the resignation or removal of the
            retiring Trustee or the retiring Note Administrator shall become effective and such successor Trustee or Note Administrator, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts, duties and
            obligations of the retiring Trustee or Note Administrator, as the case may be; but, on request of the Issuer, the Co-Issuer, a Majority of the Controlling Class, the Collateral Manager or the successor Trustee or Note Administrator, such
            retiring Trustee or Note Administrator shall, upon payment of its fees, indemnities and other amounts then unpaid, execute and deliver an instrument transferring to such successor Trustee or Note Administrator all the rights, powers and trusts
            of the retiring Trustee or Note Administrator, as the case may be, and shall duly assign, transfer and deliver to such successor Trustee or Note Administrator all property and amounts held by such retiring Trustee or Note Administrator
            hereunder, subject nevertheless to its lien, if any, provided for in Section 6.7(d).  Upon request of any such successor Trustee or Note Administrator, the Issuer and
            the Co-Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee or Note Administrator all such rights, powers and trusts.

         

        No successor Trustee or successor Note Administrator shall accept its appointment unless (a) at the time of such acceptance such
            successor shall be qualified and eligible under this Article 6, (b) such successor shall have a long-term unsecured debt rating satisfying the requirements set forth
            in Section 6.8, and (c) the Rating Agency Condition is satisfied.

        Section 6.11       Merger, Conversion, Consolidation or Succession to Business of Trustee and Note Administrator.

         

        Any corporation or banking association into which the Trustee or the Note Administrator may be merged or converted or with which it
            may be consolidated, or any corporation or banking association resulting from any merger, conversion or consolidation to which the Trustee or the Note Administrator, shall be a party, or any corporation or banking association succeeding to all
            or substantially all of the corporate trust business of the Trustee or the Note Administrator, shall be the successor of the Trustee or the Note Administrator, as applicable, hereunder; provided that with respect to the Trustee, such corporation or banking association shall be otherwise qualified and eligible under this Article 6,
            without the execution or filing of any paper or any further act on the part of any of the parties hereto.  In case any of the Notes have been authenticated, but not delivered, by the Note Administrator then in office, any successor by merger,
            conversion or consolidation to such authenticating Note Administrator may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Note Administrator had itself authenticated such Notes.

         

        Section 6.12       Co-Trustees and Separate Trustee.

         

        At any time or times, including, but not limited to, for the purpose of meeting the legal requirements of any jurisdiction in which
            any part of the Collateral may at the time be located, for enforcement actions, or where a conflict of interest exists, the Trustee shall have power to appoint, one or more Persons to act as co‐trustee jointly with the Trustee or as a separate
            trustee with respect to of all or any part of the Collateral, with the power to file such proofs of claim and take such other actions pursuant to Section 5.6 herein
            and to make such claims and enforce such rights of action on behalf of the Holders of the Notes as such Holders themselves may have the right to do, subject to the other provisions of this Section 6.12.

         

        Each of the Issuer and the Co-Issuer shall join with the Trustee in the execution, delivery and performance of all instruments and
            agreements necessary or proper to appoint a co-trustee.  If the Issuer and the Co-Issuer do not both join in such appointment within 15 days after the receipt by them of a request to do so, the Trustee shall have power to make such appointment
            on its own.

         

        Should any written instrument from the Issuer or the Co-Issuer be required by any co-trustee, so appointed, more fully confirming to
            such co-trustee such property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Issuer or the Co-Issuer, as the case may be.  The Issuer agrees to pay (but only from and to
            the extent of the Collateral) to the extent funds are available therefor under the Priority of Payments, for any reasonable fees and expenses in connection with such appointment.

         

        Every co-trustee, shall, to the extent permitted by law, but to such extent only, be appointed subject to the following terms:

         

        (a)           all rights, powers, duties and obligations
            hereunder in respect of the custody of securities, Cash and other personal property held by, or required to be deposited or pledged with, the Trustee hereunder, shall be exercised solely by the Trustee;

         

          

        
          -111-

          
            


        

        (b)          the rights, powers, duties and obligations
            hereby conferred or imposed upon the Trustee in respect of any property covered by the appointment of a co-trustee shall be conferred or imposed upon and exercised or performed by the Trustee or by the Trustee and such co-trustee jointly in the
            case of the appointment of a co-trustee as shall be provided in the instrument appointing such co-trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Trustee shall be
            incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by a co-trustee;

         

        (c)           the Trustee at any time, by an instrument in
            writing executed by it, with the concurrence of the Issuer and the Co-Issuer evidenced by an Issuer Order, may accept the resignation of, or remove, any co-trustee appointed under this Section 6.12, and in case an Event of Default has occurred and is continuing, the Trustee shall have the power to accept the resignation of, or remove, any such co-trustee without the concurrence of the Issuer or the
            Co-Issuer.  A successor to any co-trustee so resigned or removed may be appointed in the manner provided in this Section 6.12;

         

        (d)         no co-trustee hereunder shall be personally
            liable by reason of any act or omission of the Trustee hereunder, and any co-trustee hereunder shall be entitled to all the privileges, rights and immunities under Article 6 hereof, as if it were named the Trustee hereunder;

         

        (e)           except as required by applicable law, the
            appointment of a co-trustee or separate trustee under this Section 6.12 shall not relieve the Trustee of its duties and responsibilities hereunder; and

         

        (f)           any Act of Securityholders delivered to the
            Trustee shall be deemed to have been delivered to each co-trustee.

         

        Section 6.13        Direction to enter into the Servicing Agreement.

         

        The Issuer hereby directs the Trustee and the Note Administrator to enter into the Servicing Agreement.  Each of the Trustee and the
            Note Administrator shall be entitled to the same rights, protections, immunities and indemnities afforded to each herein in connection with any matter contained in the Servicing Agreement.

         

        Section 6.14        Representations and Warranties of the Trustee.

         

        The Trustee represents and warrants for the benefit of the other parties to this Indenture and the parties to the Servicing
            Agreement that:

         

        (a)          the Trustee is a national banking association
            with trust powers, duly and validly existing under the laws of the United States of America, with corporate power and authority to execute, deliver and perform its obligations under this Indenture and the Servicing Agreement, and is duly
            eligible and qualified to act as Trustee under this Indenture and the Servicing Agreement;

         

          

        
          -112-

          
            


        

        (b)          this Indenture and the Servicing Agreement have
            each been duly authorized, executed and delivered by the Trustee and each constitutes the valid and binding obligation of the Trustee, enforceable against it in accordance with its terms except (i) as limited by bankruptcy, fraudulent
            conveyance, fraudulent transfer, insolvency, reorganization, liquidation, receivership, moratorium or other similar laws now or hereafter in effect relating to creditors’ rights generally and by general equitable principles, regardless of
            whether considered in a proceeding in equity or at law, and (ii) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any
            proceeding therefor may be brought;

         

        (c)           neither the execution, delivery and performance
            of this Indenture or the Servicing Agreement, nor the consummation of the transactions contemplated by this Indenture or the Servicing Agreement, (i) is prohibited by, or requires the Trustee to obtain any consent, authorization, approval or
            registration under, any law, statute, rule, regulation, or any judgment, order, writ, injunction or decree that is binding upon the Trustee or any of its properties or Collateral or (ii) will violate the provisions of the Governing Documents of
            the Trustee; and

         

        (d)           there are no proceedings
            pending or, to the best knowledge of the Trustee, threatened against the Trustee before any Federal, state or other governmental agency, authority, administrator or regulatory body, arbitrator, court or other tribunal, foreign or domestic,
            which could have a material adverse effect on the Collateral or the performance by the Trustee of its obligations under this Indenture or the Servicing Agreement.

         

        Section 6.15        Representations and Warranties of the Note Administrator.

         

        The Note Administrator represents and warrants for the benefit of the other parties to this Indenture and the parties to the
            Servicing Agreement that:

         

        (a)         the Note Administrator is a national banking
            association with trust powers, duly and validly existing under the laws of the United States of America, with corporate power and authority to execute, deliver and perform its obligations under this Indenture and the Servicing Agreement, and is

        (b)           this Indenture and the Servicing Agreement have
            each been duly authorized, executed and delivered by the Note Administrator and each constitutes the valid and binding obligation of the Note Administrator, enforceable against it in accordance with its terms except (i) as limited by
            bankruptcy, fraudulent conveyance, fraudulent transfer, insolvency, reorganization, liquidation, receivership, moratorium or other similar laws now or hereafter in effect relating to creditors’ rights generally and by general equitable
            principles, regardless of whether considered in a proceeding in equity or at law, and (ii) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of
            the court before which any proceeding therefor may be brought;

         

        (c)        neither the execution, delivery and performance of
            this Indenture of the Servicing Agreement, nor the consummation of the transactions contemplated by this Indenture or the Servicing Agreement, (i) is prohibited by, or requires the Note Administrator to obtain any consent, authorization,
            approval or registration under, any law, statute, rule, regulation, or any judgment, order, writ, injunction or decree that is binding upon the Note Administrator or any of its properties or Collateral or (ii) will violate the provisions of the
            Governing Documents of the Note Administrator; and

         

          

        
          -113-

          
            


        

        (d)          there are no proceedings pending or, to the best
            knowledge of the Note Administrator, threatened against the Note Administrator before any Federal, state or other governmental agency, authority, administrator or regulatory body, arbitrator, court or other tribunal, foreign or domestic, which
            could have a material adverse effect on the Collateral or the performance by the Note Administrator of its obligations under this Indenture or the Servicing Agreement.

         

        Section 6.16        Requests for Consents.

         

        In the event that the Trustee and Note Administrator receives written notice of any offer or any request for a waiver, consent,
            amendment or other modification with respect to any Collateral Interest (before or after any default) or in the event any action is required to be taken in respect to a Loan Document, the Note Administrator shall promptly forward such notice to
            the Issuer, the Servicer and the Special Servicer.  The Special Servicer shall take such action as required under the Servicing Agreement as described in Section 10.10(f).

         

        Section 6.17        Withholding.

         

        (a)         If any amount is required to be deducted or
            withheld from any payment to any Noteholder or other payee, such amount shall reduce the amount otherwise distributable to such Noteholder or payee.  The Note Administrator is hereby authorized to withhold or deduct from amounts otherwise
            distributable to any Noteholder or other payee sufficient funds for the payment of any tax that is legally required to be withheld or deducted (but such authorization shall not prevent the Note Administrator from contesting any such tax in
            appropriate proceedings and legally withholding payment of such tax, pending the outcome of such proceedings).  The amount of any withholding tax imposed with respect to any Noteholder or other payee shall be treated as Cash distributed to such
            Noteholder or payee at the time it is deducted or withheld by the Issuer or the Note Administrator, as applicable, and remitted to the appropriate taxing authority.  If there is a possibility that withholding tax is payable with respect to a
            distribution, the Note Administrator may in its sole discretion withhold such amounts in accordance with this Section 6.17.  The Issuer and the Co-Issuer agree to
            timely provide to the Note Administrator accurate and complete copies of all documentation received from Noteholders pursuant to Sections 2.7(f) and 2.11(c).  Solely with respect to FATCA compliance and reporting, nothing herein shall impose an obligation on the part of the Note Administrator to determine the amount of
            any tax or withholding obligation on the part of the Issuer or in respect of the Notes.  In addition, initial purchasers and transferees of Definitive Notes after the Closing Date will be required to provide to the Issuer, the Trustee, the Note
            Administrator, or their agents, all information, documentation or certifications reasonably required to permit the Issuer to comply with its tax reporting obligations under applicable law, including any applicable cost basis reporting
            obligation.  For the avoidance of doubt, the Note Administrator will have no responsibility for the preparation of any tax returns or related reports on behalf of or for the benefit of the Issuer or any noteholder, or the calculation of any
            original issue discount on the Notes.

         

          

        
          -114-

          
            


        

        (b)         For the avoidance of doubt, the Note
            Administrator shall reasonably cooperate with Issuer, at Issuer’s direction and expense, to permit Issuer to fulfill its obligations under FATCA; provided that the
            Note Administrator shall have no independent obligation to cause or maintain Issuer’s compliance with FATCA and shall have no liability for any withholding on payments to Issuer as a result of Issuer’s failure to achieve or maintain FATCA
            compliance.

         

        Section 6.18      Registrar of Participation Holders

         

        Pursuant to each related Participation Agreement and Section
                3.25(b) of the Servicing Agreement, the Note Administrator shall maintain the registrar for the Participation holders under such Participation Agreement on behalf of the Issuer, for so long as the related Pari Passu Participation
            is included in this KREF 2018-FL1 securitization.  The Note Administrator shall maintain the registrar of Participation holders and facilitate transfers in accordance with the terms of the related Participation Agreement and as compensation
            therefor shall be entitled to the Participation Fee payable in accordance with the Servicing Agreement.

        Section 7.1        Payment of Principal and Interest.

         

        The Issuer and the Co-Issuer shall duly and punctually pay the principal of and interest on each Class of Notes in accordance with
            the terms of this Indenture.  Amounts properly withheld under the Code or other applicable law by any Person from a payment to any Noteholder of interest and/or principal shall be considered as having been paid by the Issuer and the Co-Issuer,
            and, with respect to the Preferred Shares, by the Issuer, to such Preferred Shareholder for all purposes of this Indenture.

         

        The Note Administrator shall, unless prevented from doing so for reasons beyond its reasonable control, give notice to each
            Securityholder of any such withholding requirement no later than ten days prior to the related Payment Date from which amounts are required, as directed by the Issuer (or the Collateral Manager on its behalf) to be withheld, provided that, despite the failure of the Note Administrator to give such notice, amounts withheld pursuant to applicable tax laws shall be considered as having been paid
            by the Issuer and the Co-Issuer, as provided above.

         

        Section 7.2        Maintenance of Office or Agency.

         

        The Co-Issuers hereby appoint the Note Administrator as a Paying Agent for the payment of principal of and interest on the Notes and
            where Notes may be surrendered for registration of transfer or exchange and the Issuer hereby appoints Corporation Service Company in New York, New York, as its agent where notices and demands to or upon the Issuer in respect of the Notes or
            this Indenture may be served.

         

          

        
          -115-

          
            


        

        The Issuer may at any time and from time to time vary or terminate the appointment of any such agent or appoint any additional
            agents for any or all of such purposes; provided, however, that the Issuer will maintain in the Borough of Manhattan, The City of New York, an office or agency where notices and demands to or upon the Issuer in respect of the Notes and
            this Indenture may be served, and, subject to any laws or regulations applicable thereto, an office or agency outside of the United States where Notes may be presented and surrendered for payment; provided, further, that no paying agent
            shall be appointed in a jurisdiction which subjects payments on the Notes to withholding tax.  The Issuer shall give prompt written notice to the Trustee, the Note Administrator, the Rating Agencies and the Noteholders of the appointment or
            termination of any such agent and of the location and any change in the location of any such office or agency.

         

        If at any time the Issuer shall fail to maintain any such required office or agency in the Borough of Manhattan, The City of New
            York, or outside the United States, or shall fail to furnish the Trustee and the Note Administrator with the address thereof, presentations and surrenders may be made (subject to the limitations described in the preceding paragraph) at and
            notices and demands may be served on the Issuer and Co-Issuer and Notes may be presented and surrendered for payment to the appropriate Paying Agent at its main office and the Issuer and the Co-Issuer hereby appoint the same as their agent to
            receive such respective presentations, surrenders, notices and demands.

         

        Section 7.3          Amounts for Note Payments to be Held in Trust.

         

        (a)          All payments of amounts due and payable with
            respect to any Notes that are to be made from amounts withdrawn from the Payment Account shall be made on behalf of the Issuer and the Co-Issuer by the Note Administrator or a Paying Agent (in each case, from and to the extent of available
            funds in the Payment Account and subject to the Priority of Payments) with respect to payments on the Notes.

         

        When the Paying Agent is not also the Notes Registrar, the Issuer and the Co-Issuer shall furnish, or cause the Notes Registrar to
            furnish, no later than the fifth calendar day after each Record Date a list, if necessary, in such form as such Paying Agent may reasonably request, of the names and addresses of the Holders of Notes and of the certificate numbers of individual
            Notes held by each such Holder together with wiring instructions, contact information, and such other information reasonably required by the paying agent.

         

        Whenever the Paying Agent is not also the Note Administrator, the Issuer, the Co-Issuer, and such Paying Agent shall, on or before
            the Business Day next preceding each Payment Date or Redemption Date, as the case may be, direct the Note Administrator to deposit on such Payment Date with such Paying Agent, if necessary, an aggregate sum sufficient to pay the amounts then
            becoming due pursuant to the terms of this Indenture (to the extent funds are then available for such purpose in the Payment Account, and subject to the Priority of Payments), such sum to be held for the benefit of the Persons entitled thereto
            and (unless such Paying Agent is the Note Administrator) the Issuer and the Co-Issuer shall promptly notify the Note Administrator of its action or failure so to act.  Any amounts deposited with a Paying Agent (other than the Note
            Administrator) in excess of an amount sufficient to pay the amounts then becoming due on the Notes with respect to which such deposit was made shall be paid over by such Paying Agent to the Note Administrator for application in accordance with
            Article 11.  Any such Paying Agent shall be deemed to agree by assuming such role not to cause the filing of a petition in bankruptcy against the Issuer, the Co-Issuer
            or any Permitted Subsidiary for the non-payment to the Paying Agent of any amounts payable thereto until at least one year and one day (or, if longer, the applicable preference period then in effect) after the payment in full of all Notes
            issued under this Indenture.

         

          

        
          -116-

          
            


        

        The initial Paying Agent shall be as set forth in Section 7.2. Any additional or successor Paying Agents shall be appointed by Issuer Order of the
            Issuer and Issuer Order of the Co-Issuer and at the sole cost and expense (including such Paying Agent’s fee) of the Issuer and the Co‐Issuer, with written notice thereof to the Note Administrator; provided, however, that so long as any
            Class of the Notes are rated by a Rating Agency and with respect to any additional or successor Paying Agent for the Notes, either (i) such Paying Agent has a long-term unsecured debt rating of “Aa3” or higher by Moody’s or (ii) each of the
            Rating Agencies confirms that employing such Paying Agent shall not adversely affect the then-current ratings of the Notes.  In the event that such successor Paying Agent ceases to have a long-term debt rating of “Aa3” or higher by Moody’s, the
            Issuer and the Co-Issuer shall promptly remove such Paying Agent and appoint a successor Paying Agent.  The Issuer and the Co-Issuer shall not appoint any Paying Agent that is not, at the time of such appointment, a depository institution or
            trust company subject to supervision and examination by federal and/or state and/or national banking authorities.  The Issuer and the Co-Issuer shall cause the Paying Agent other than the Note Administrator to execute and deliver to the Note
            Administrator an instrument in which such Paying Agent shall agree with the Note Administrator (and if the Note Administrator acts as Paying Agent, it hereby so agrees), subject to the provisions of this Section 7.3, that such Paying Agent will:

         

        (i)           allocate
            all sums received for payment to the Holders of Notes in accordance with the terms of this Indenture;

         

        (ii)         hold all
            sums held by it for the payment of amounts due with respect to the Notes for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided and pay such sums to such Persons
            as herein provided;

         

        (iii)         if such
            Paying Agent is not the Note Administrator, immediately resign as a Paying Agent and forthwith pay to the Note Administrator all sums held by it for the payment of Notes if at any time it ceases to satisfy the standards set forth above required
            to be met by a Paying Agent at the time of its appointment;

         

        (iv)          if such
            Paying Agent is not the Note Administrator, immediately give the Note Administrator notice of any Default by the Issuer or the Co-Issuer (or any other obligor upon the Notes) in the making of any payment required to be made; and

         

          

        
          -117-

          
            


        

        (v)           if such
            Paying Agent is not the Note Administrator at any time during the continuance of any such Default, upon the written request of the Note Administrator, forthwith pay to the Note Administrator all sums so held by such Paying Agent.

         

        The Issuer or the Co-Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for
            any other purpose, pay, or by Issuer Order direct the Paying Agent to pay, to the Note Administrator all sums held by the Issuer or the Co-Issuer or held by the Paying Agent for payment of the Notes, such sums to be held by the Note
            Administrator in trust for the same Noteholders as those upon which such sums were held by the Issuer, the Co-Issuer or the Paying Agent; and, upon such payment by the Paying Agent to the Note Administrator, the Paying Agent shall be released
            from all further liability with respect to such amounts.

         

        Except as otherwise required by applicable law, any amounts deposited with the Note Administrator in trust or deposited with the
            Paying Agent for the payment of the principal of or interest on any Note and remaining unclaimed for two years after such principal or interest has become due and payable shall be paid to the Issuer on request; and the Holder of such Note shall
            thereafter, as an unsecured general creditor, look only to the Issuer for payment of such amounts and all liability of the Note Administrator or the Paying Agent with respect to such amounts (but only to the extent of the amounts so paid to the
            Issuer or the Co-Issuer, as applicable) shall thereupon cease.  The Note Administrator or the Paying Agent, before being required to make any such release of payment, may, but shall not be required to, adopt and employ, at the expense of the
            Issuer or the Co-Issuer, as the case may be, any reasonable means of notification of such release of payment, including, but not limited to, mailing notice of such release to Holders whose Notes have been called but have not been surrendered
            for redemption or whose right to or interest in amounts due and payable but not claimed is determinable from the records of the Paying Agent, at the last address of record of each such Holder.

         

        Section 7.4         Existence of the Issuer and Co-Issuer.

         

        (a)          So long as any Note is Outstanding, the Issuer
            shall, to the maximum extent permitted by applicable law, maintain in full force and effect its existence and rights as an exempted company incorporated with limited liability under the laws of the Cayman Islands and shall obtain and preserve
            its qualification to do business as a foreign limited liability company in each jurisdiction in which such qualifications are or shall be necessary to protect the validity and enforceability of this Indenture, the Notes or any of the
            Collateral; provided that the Issuer shall be entitled to change its jurisdiction of registration from the Cayman Islands to any other jurisdiction reasonably
            selected by the Issuer so long as (i) such change is not disadvantageous in any material respect to the Holders of the Notes or the Preferred Shares, (ii) it delivers written notice of such change to the Note Administrator for delivery to the
            Holders of the Notes or Preferred Shares, the Preferred Share Paying Agent and the Rating Agencies and (iii) on or prior to the fifteenth (15th) Business Day following delivery of such notice by the Note Administrator to the Noteholders, the
            Note Administrator shall not have received written notice from a Majority of the Controlling Class or a Majority of Preferred Shareholders objecting to such change.  So long as any Rated Notes are Outstanding, the Issuer will maintain at all
            times at least one director who is Independent of the Collateral Manager and its Affiliates.

         

          

        
          -118-

          
            


        

        (b)         So long as any Note is Outstanding, the Co-Issuer
            shall maintain in full force and effect its existence and rights as a limited liability company organized under the laws of Delaware and shall obtain and preserve its qualification to do business as a foreign limited liability company in each
            jurisdiction in which such qualifications are or shall be necessary to protect the validity and enforceability of this Indenture or the Notes; provided, however, that the Co-Issuer shall be entitled to change its jurisdiction of
            formation from Delaware to any other jurisdiction reasonably selected by the Co-Issuer so long as (i) such change is not disadvantageous in any material respect to the Holders of the Notes, (ii) it delivers written notice of such change to the
            Note Administrator for delivery to the Holders of the Notes and the Rating Agencies and (iii) on or prior to the fifteenth (15th) Business Day following such delivery of such notice by the Note Administrator to the Noteholders, the Note
            Administrator shall not have received written notice from a Majority of the Controlling Class objecting to such change.  So long as any Rated Notes are Outstanding, the Co‐Issuer will maintain at all times at least one director who is
            Independent of the Collateral Manager and its Affiliates.

         

        (c)         So long as any Note is Outstanding, the Issuer
            shall ensure that all corporate or other formalities regarding its existence are followed (including correcting any known misunderstanding regarding its separate existence).  So long as any Note is Outstanding, the Issuer shall not take any
            action or conduct its affairs in a manner that is likely to result in its separate existence being ignored or its Collateral and liabilities being substantively consolidated with any other Person in a bankruptcy, reorganization or other
            insolvency proceeding.  So long as any Note is Outstanding, the Issuer shall maintain and implement administrative and operating procedures reasonably necessary in the performance of the Issuer’s obligations hereunder, and the Issuer shall at
            all times keep and maintain, or cause to be kept and maintained, separate books, records, accounts and other information customarily maintained for the performance of the Issuer’s obligations hereunder.  Without limiting the foregoing, so long
            as any Note is Outstanding, (i) the Issuer shall (A) pay its own liabilities only out of its own funds and (B) use separate stationery, invoices and checks, (C) hold itself out and identify itself as a separate and distinct entity under its own
            name; (D) not commingle its assets with assets of any other Person; (E) hold title to its assets in its own name; (F) maintain separate financial statements, showing its assets and liabilities separate and apart from those of any other Person
            and not have its assets listed on any financial statement of any other Person; provided, however, that the Issuer’s assets may be included in a consolidated financial statement of its Affiliate provided that (1) appropriate notation shall be
            made on such consolidated financial statements to indicate the separateness of the Issuer from such Affiliate and to indicate that the Issuer’s assets and credit are not available to satisfy the debts and other obligations of such Affiliate or
            any other Person and (2) such assets shall also be listed on the Issuer’s own balance sheet; (G) not guarantee any obligation of any Person, including any Affiliate or become obligated for the debts of any other Person or hold out its credit or
            assets as being available to satisfy the obligations of others; (H) allocate fairly and reasonably any overhead expenses, including for shared office space; (I) not have its obligations guaranteed by any Affiliate; (J) not pledge its assets to
            secure the obligations of any other Person; (K) correct any known misunderstanding regarding its separate identity; (L) maintain adequate capital in light of its contemplated business purpose, transactions and liabilities; (M) not acquire any
            securities of any Affiliate of the Issuer; and (N) not own any asset or property other than property arising out of the actions permitted to be performed under the Transaction Documents; and (ii) the Issuer shall not (A) have any subsidiaries
            (other than a Permitted Subsidiary and, in the case of the Issuer, the Co-Issuer); (B) engage, directly or indirectly, in any business other than the actions required or permitted to be performed under the Transaction Documents; (C) engage in
            any transaction with any shareholder that is not permitted under the terms of the Servicing Agreement; (D) pay dividends other than in accordance with the terms of this Indenture, its governing documents and the Preferred Share Paying Agency
            Agreement; (E) conduct business under an assumed name (i.e., no “DBAs”); (F) incur, create or assume any indebtedness other than as expressly permitted under the
            Transaction Documents; (G) enter into any contract or agreement with any of its Affiliates, except upon terms and conditions that are commercially reasonable and substantially similar to those available in arm’s-length transactions; provided that the foregoing shall not prohibit the Issuer from entering into the transactions contemplated by the Company Administration Agreement with the Company
            Administrator, the Preferred Share Paying Agency Agreement with the Share Registrar and any other agreement contemplated or permitted by the Servicing Agreement or this Indenture; (H) make or permit to remain outstanding any loan or advance to,
            or own or acquire any stock or securities of, any Person, except that the Issuer may invest in those investments permitted under the Transaction Documents and may make any advance required or expressly permitted to be made pursuant to any
            provisions of the Transaction Documents and permit the same to remain outstanding in accordance with such provisions; (I) to the fullest extent permitted by law, engage in any dissolution, liquidation, consolidation, merger, asset sale or
            transfer of ownership interests other than such activities as are expressly permitted pursuant to any provision of the Transaction Documents.

        (d)         So long as any Note is Outstanding, the Co-Issuer
            shall ensure that all limited liability company or other formalities regarding its existence are followed, as well as correcting any known misunderstanding regarding its separate existence.  The Co-Issuer shall not take any action or conduct
            its affairs in a manner, that is likely to result in its separate existence being ignored or its Collateral and liabilities being substantively consolidated with any other Person in a bankruptcy, reorganization or other insolvency proceeding. 
            The Co-Issuer shall maintain and implement administrative and operating procedures reasonably necessary in the performance of the Co-Issuer’s obligations hereunder, and the Co-Issuer shall at all times keep and maintain, or cause to be kept and
            maintained, books, records, accounts and other information customarily maintained for the performance of the Co-Issuer’s obligations hereunder.  Without limiting the foregoing, the Co-Issuer shall not (A) have any subsidiaries, (B) have any
            employees (other than its managers), (C) join in any transaction with any member that is not permitted under the terms of the Servicing Agreement or this Indenture, (D) pay dividends other than in accordance with the terms of this Indenture,
            (E) commingle its funds or Collateral with those of any other Person, or (F) enter into any contract or agreement with any of its Affiliates, except upon terms and conditions that are commercially reasonable and substantially similar to those
            available in arm’s-length transactions with an unrelated party.

        Section 7.5          Protection of Collateral.

         

        (a)           The Note Administrator, at the expense of the
            Issuer, upon receipt of any Opinion of Counsel received pursuant to Section 7.5(d) shall execute and deliver all such Financing Statements, continuation statements,
            instruments of further assurance and other instruments, and may take such other action as may be necessary or advisable or desirable to secure the rights and remedies of the Secured Parties hereunder and to:

         

        (i)            Grant
            more effectively all or any portion of the Collateral;

         

        (ii)           maintain


            or preserve the lien (and the priority thereof) of this Indenture or to carry out more effectively the purposes hereof;

         

        (iii)         perfect,
            publish notice of or protect the validity of any Grant made or to be made by this Indenture (including, without limitation, any and all actions necessary or desirable as a result of changes in law or regulations);

         

        (iv)          cooperate


            with the Servicer and the Special Servicer with respect to enforcement on any of the Collateral Interests or enforce on any other instruments or property included in the Collateral;

         

        (v)          instruct
            the Special Servicer to preserve and defend title to the Collateral Interests and preserve and defend title to the other Collateral and the rights of the Trustee, the Holders of the Notes in the Collateral against the claims of all persons and
            parties; and

         

        (vi)         pursuant
            to Sections 11.1(a)(i)(1) and 11.1(a)(ii)(1), pay or cause to be
            paid any and all taxes levied or assessed upon all or any part of the Collateral.

         

        The Issuer hereby designates the Note Administrator as its agent and attorney-in-fact to execute any Financing Statement,
            continuation statement or other instrument required pursuant to this Section 7.5.  The Note Administrator agrees that it will from time to time execute and cause such
            Financing Statements and continuation statements to be filed (it being understood that the Note Administrator shall be entitled to rely upon an Opinion of Counsel described in Section


                7.5(d), at the expense of the Issuer, as to the need to file such Financing Statements and continuation statements, the dates by which such filings are required to be made and the jurisdictions in which such filings are required
            to be made).

         

        (b)         Neither the Trustee nor the Note Administrator
            shall (except in accordance with Section 10.12(a), (b) or (c) and except for payments, deliveries and distributions otherwise expressly permitted under this Indenture) cause or permit the Custodial Account or the Custodian to be located in a different
            jurisdiction from the jurisdiction in which the Custodian was located on the Closing Date, unless the Trustee or the Note Administrator, as applicable, shall have first received an Opinion of Counsel to the effect that the lien and security
            interest created by this Indenture with respect to such property will continue to be maintained after giving effect to such action or actions.

         

          

        
          -121-

          
            


        

        (c)         The Issuer shall (i) pay or cause to be paid
            taxes, if any, levied on account of the beneficial ownership by the Issuer of any Collateral that secure the Notes and timely file all tax returns and information statements as required, (ii) take all actions necessary or advisable to prevent
            the Issuer from becoming subject to any withholding or other taxes or assessments and to allow the Issuer to comply with FATCA, and (iii) if required to prevent the withholding or imposition of United States income tax, deliver or cause to be
            delivered a United States IRS Form W‐9 (or the applicable IRS Form W‐8, if appropriate) or successor applicable form, to each borrower, counterparty or paying agent with respect to (as applicable) an item included in the Collateral at the time
            such item is purchased or entered into and thereafter prior to the expiration or obsolescence of such form.

         

        (d)          For so long as the Notes are Outstanding, on or
            about June 2023 and every 60 months thereafter, the Issuer (or the Collateral Manager on its behalf) shall deliver to the Trustee and the Note Administrator, for the benefit of the Trustee, the Collateral Manager, the Note Administrator and the
            Rating Agencies, at the expense of the Issuer, an Opinion of Counsel stating what is required, in the opinion of such counsel, as of the date of such opinion, to maintain the lien and security interest created by this Indenture with respect to
            the Collateral, and confirming the matters set forth in the Opinion of Counsel, furnished pursuant to Section 3.1(d), with regard to the perfection and priority of
            such security interest (and such Opinion of Counsel may likewise be subject to qualifications and assumptions similar to those set forth in the Opinion of Counsel delivered pursuant to Section 3.1(d)).

         

        Section 7.6          Notice of Any Amendments.

         

        Each of the Issuer and the Co-Issuer shall give notice to the 17g‐5 Information Provider of, and satisfy the Rating Agency Condition
            with respect to, any amendments to its Governing Documents.

         

        Section 7.7          Performance of Obligations.

         

        (a)          Each of the Issuer and the
            Co-Issuer shall not take any action, and will use commercially reasonable efforts not to permit any action to be taken by others, that would release any Person from any of such Person’s covenants or obligations under any Instrument included in
            the Collateral, except in the case of enforcement action taken with respect to any Defaulted Collateral Interest in accordance with the provisions hereof and as otherwise required hereby.

         

        (b)          The Issuer or the Co-Issuer may, with the prior
            written consent of the Majority of the Notes (or if there are no Notes Outstanding, a Majority of Preferred Shareholders), contract with other Persons, including the Servicer, the Special Servicer, the Note Administrator, the Collateral Manager
            or the Trustee, for the performance of actions and obligations to be performed by the Issuer or the Co-Issuer, as the case may be, hereunder by such Persons and the performance of the actions and other obligations with respect to the Collateral
            of the nature set forth in the Indenture.  Notwithstanding any such arrangement, the Issuer or the Co-Issuer, as the case may be, shall remain primarily liable with respect thereto.  In the event of such contract, the performance of such
            actions and obligations by such Persons shall be deemed to be performance of such actions and obligations by the Issuer or the Co-Issuer; and the Issuer or the Co-Issuer shall punctually perform, and use commercially reasonable efforts to cause
            the Servicer, the Special Servicer, the Collateral Manager or such other Person to perform, all of their obligations and agreements contained in the Indenture or such other agreement.

         

          

        
          -122-

          
            


        

        (c)          Unless the Rating Agency Condition is satisfied
            with respect thereto, the Issuer shall maintain the Servicing Agreement in full force and effect so long as any Notes remain Outstanding and shall not terminate the Servicing Agreement with respect to any Collateral Interest except upon the
            sale or other liquidation of such Collateral Interest in accordance with the terms and conditions of this Indenture.

         

        (d)          If the Co-Issuers receive a notice from the
            Rating Agencies stating that they are not in compliance with Rule 17g-5, the Co-Issuers shall take such action as mutually agreed between the Co-Issuers and the Rating Agencies in order to comply with Rule 17g-5.

         

        Section 7.8          Negative Covenants.

         

        (a)           The Issuer and the Co-Issuer shall not:

         

        (i)           sell,
            assign, participate, transfer, exchange or otherwise dispose of, or pledge, mortgage, hypothecate or otherwise encumber (or permit such to occur or suffer such to exist), any part of the Collateral, except as otherwise expressly permitted by
            this Indenture or the Servicing Agreement;

         

        (ii)          claim
            any credit on, make any deduction from, or dispute the enforceability of, the payment of the principal or interest payable in respect of the Notes (other than amounts required to be paid, deducted or withheld in accordance with any applicable
            law or regulation of any governmental authority) or assert any claim against any present or future Noteholder by reason of the payment of any taxes levied or assessed upon any part of the Collateral;

         

        (iii)         (A)
            incur or assume or guarantee any indebtedness, other than the Notes and this Indenture and the transactions contemplated hereby; (B) issue any additional class of securities, other than the Notes, the Preferred Shares, the ordinary shares of
            the Issuer and the limited liability company membership interests of the Co-Issuer; or (C) issue any additional shares of stock, other than the ordinary shares of the Issuer and the Preferred Shares;

         

        (iv)         (A)
            permit the validity or effectiveness of this Indenture or any Grant hereunder to be impaired, or permit the lien of this Indenture to be amended, hypothecated, subordinated, terminated or discharged, or permit any Person to be released from any
            covenants or obligations with respect to this Indenture or the Notes, except as may be expressly permitted hereby; (B) permit any lien, charge, adverse claim, security interest, mortgage or other encumbrance (other than the lien of this
            Indenture) to be created on or extend to or otherwise arise upon or burden the Collateral or any part thereof, any interest therein or the proceeds thereof, except as may be expressly permitted hereby; or (C) take any action that would permit
            the lien of this Indenture not to constitute a valid first priority security interest in the Collateral, except as may be expressly permitted hereby;

            incur any capital expenditures, except as reasonably required to perform its functions in accordance with the terms of this Indenture and, in the case of the Issuer, the Preferred Share Paying Agency Agreement;

            liable in any way, whether directly or by assignment or as a guarantor or other surety, for the obligations of the lessee under any lease, hire any employees or pay any dividends to its shareholders, except with respect to the Preferred Shares

        (xi)         conduct

            name change will not adversely affect the security interest hereunder of the Trustee or the Secured Parties;

         

        (xii)        take any
            action that would result in it failing to qualify as a Qualified REIT Subsidiary or other disregarded entity of KREF Sub-REIT for U.S. federal income tax purposes (including, but not limited to, an election to treat the Issuer as a “taxable
            REIT subsidiary,” as defined in Section 856(l) of the Code), unless (A) based on an Opinion of Counsel of Dechert LLP, Hunton Andrews Kurth LLP or another nationally-recognized tax counsel experienced in such matters, the Issuer will be treated
            as a Qualified REIT Subsidiary or other disregarded entity of a REIT other than KREF Sub-REIT, or (B) based on an Opinion of Counsel of Dechert LLP, Hunton Andrews Kurth LLP or another nationally-recognized tax counsel experienced in such
            matters, the Issuer will be treated as a foreign corporation that is not engaged in a trade or business within the United States for U.S. federal income tax purposes;

         

        (xiii)      except for

            “limited recourse” provisions; or

         

        (xiv)        amend
            their respective organizational documents without satisfaction of the Rating Agency Condition in connection therewith.

        (b)          Neither the Issuer nor the Trustee shall sell,
            transfer, exchange or otherwise dispose of Collateral, or enter into or engage in any business with respect to any part of the Collateral, except as expressly permitted or required by this Indenture or the Servicing Agreement.

         

        (c)          The Co-Issuer shall not invest any of its
            Collateral in “securities” (as such term is defined in the 1940 Act) and shall keep all of the Co-Issuer’s Collateral in Cash.

         

        (d)           For so long as any of the Notes are
            Outstanding, the Co-Issuer shall not issue any limited liability company membership interests of the Co-Issuer to any Person other than KREF Sub-REIT or a wholly-owned subsidiary of KREF Sub-REIT.

         

        (e)         The Issuer shall not enter into any material new
            agreements (other than any Collateral Interest Purchase Agreement or other agreement contemplated by this Indenture) (including, without limitation, in connection with the sale of Collateral by the Issuer) without the prior written consent of
            the Holders of at least a Majority of the Notes (or if there are no Notes Outstanding, a Majority of Preferred Shareholders) and shall provide notice of all new agreements (other than any Collateral Interest or other agreement specifically
            contemplated by this Indenture) to the Holders of the Notes.  The foregoing notwithstanding, the Issuer may agree to any material new agreements; provided that (i)
            the Issuer (or the Collateral Manager on its behalf) determines that such new agreements would not, upon becoming effective, adversely affect the rights or interests of any Class or Classes of Noteholders and (ii) subject to satisfaction of the
            Rating Agency Condition.

         

        (f)           As long as any Offered Note is Outstanding, the
            Retention Holder may not transfer (whether by means of actual transfer or a transfer of beneficial ownership for U.S. federal income tax purposes), pledge or hypothecate any of the Preferred Shares or ordinary shares of the Issuer to any Person
            (except to an affiliate that is wholly-owned by KREF Sub-REIT and is disregarded for U.S. federal income tax purposes) unless the Issuer receives an opinion of Dechert LLP, Hunton Andrews Kurth LLP or another nationally recognized tax counsel
            experienced in such matters that such transfer, pledge or hypothecation will not cause the Issuer to be treated as a foreign corporation engaged in a trade or business within the United States for U.S. federal income tax purposes or otherwise
            to become subject to U.S. federal income tax on a net basis, which opinion may be conditioned on compliance with certain restrictions on the investment or other activities of the Issuer and the Collateral Manager on behalf of the Issuer (such
            opinion, a “No Entity-Level Tax Opinion”) (or has previously received a No Trade or Business Opinion) which opinion may be conditioned, in each case, on compliance
            with certain restrictions on the investment or other activities of the Issuer and the Servicer on behalf of the Issuer.

         

        (g)         Any financing arrangement pursuant to Section 7.8(f) shall prohibit any further transfer (whether by means of actual transfer or a transfer of beneficial ownership for U.S. federal income tax purposes) of the
            Retained Securities and Issuer Ordinary Shares, including a transfer in connection with any exercise of remedies under such financing unless the Issuer receives a No Entity-Level Tax Opinion.

            effect as if such Person had been named as the Issuer or the Co-Issuer, as the case may be, herein.  In the event of any such consolidation, merger, transfer or conveyance, the Person named as the “Issuer” or the “Co-Issuer” in the first
            paragraph of this Indenture or any successor which shall theretofore have become such in the manner prescribed in this Article 7 may be dissolved, wound-up and

        Section 7.13       Reporting.

         

        At any time when the Issuer and/or the Co-Issuer is not subject to Section 13 or 15(d) of the Exchange Act and is not exempt from
            reporting pursuant to Rule 12g3-2(b) under the Exchange Act, upon the request of a Holder or beneficial owner of a Note, the Issuer and/or the Co-Issuer shall promptly furnish or cause to be furnished “Rule 144A Information” (as defined below)
            to such Holder or beneficial owner, to a prospective purchaser of such Note designated by such Holder or beneficial owner or to the Note Administrator for delivery to such Holder or beneficial owner or a prospective purchaser designated by such
            Holder or beneficial owner, as the case may be, in order to permit compliance by such Holder or beneficial owner with Rule 144A under the Securities Act in connection with the resale of such Note by such Holder or beneficial owner.  “Rule 144A Information” shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act (or any successor provision thereto).  The Note
            Administrator shall reasonably cooperate with the Issuer and/or the Co-Issuer in mailing or otherwise distributing (at the Issuer’s expense) to such Noteholders or prospective purchasers, at and pursuant to the Issuer’s and/or the Co-Issuer’s
            written direction the foregoing materials prepared by or on behalf of the Issuer and/or the Co-Issuer; provided, however, that the Note Administrator shall be entitled to prepare and affix thereto or enclose therewith reasonable disclaimers
            to the effect that such Rule 144A Information was not assembled by the Note Administrator, that the Note Administrator has not reviewed or verified the accuracy thereof, and that it makes no representation as to such accuracy or as to the
            sufficiency of such information under the requirements of Rule 144A or for any other purpose.

         

        Section 7.14       Calculation Agent.

         

        (a)          The Issuer and the Co-Issuer hereby agree that
            for so long as any Notes remain Outstanding there shall at all times be an agent appointed to calculate LIBOR in respect of each Interest Accrual Period in accordance with the terms of Schedule B attached hereto (the “Calculation Agent”).  The Issuer and the Co-Issuer initially have appointed the Note Administrator as
            Calculation Agent for purposes of determining LIBOR for each Interest Accrual Period.  The Calculation Agent may be removed by the Issuer at any time with cause, and upon no less than thirty (30) days’ notice without cause.  The Calculation
            Agent may resign at any time by giving written notice thereof to the Issuer, the Co-Issuer, the Collateral Manager, the Noteholders and the Rating Agencies.  If the Calculation Agent is unable or unwilling to act as such or is removed by the
            Issuer in respect of any Interest Accrual Period, the Issuer and the Co-Issuer shall promptly appoint as a replacement Calculation Agent a leading bank which is engaged in transactions in Eurodollar deposits in the international Eurodollar
            market and which does not control or is not controlled by or under common control with the Issuer or its Affiliates.  The Calculation Agent may not resign its duties without a successor having been duly appointed.  If no successor Calculation
            Agent shall have been appointed within 30 days after giving of a notice of resignation, the resigning Calculation Agent or a Majority of the Holders of the Notes, on behalf of himself and all others similarly situated, may petition a court of
            competent jurisdiction, at the Issuer’s expense, for the appointment of a successor Calculation Agent.

         

        (b)           The Calculation Agent shall be required to
            agree that, as soon as practicable after 11:00 a.m. (London time) on each LIBOR Determination Date (as defined in Schedule B attached hereto), but in no event later
            than 11:00 a.m. (New York time) on the London Banking Day immediately following each LIBOR Determination Date, the Calculation Agent shall calculate LIBOR (or in the event that the Notes convert to the Substitute Index, the Substitute Index, as
            applicable) for the next Interest Accrual Period and will communicate such information to the Note Administrator, who shall include such calculation on the next Monthly Report following such Libor Determination Date.  The Calculation Agent
            shall notify the Issuer, the Co-Issuer and the Collateral Manager before 5:00 p.m. (New York time) on each LIBOR Determination Date if it has not determined and is not in the process of determining LIBOR and the Interest Distribution Amounts
            for each Class of Notes, together with the reasons therefor.  The determination of the Note Interest Rates and the related Interest Distribution Amounts, respectively, by the Calculation Agent shall, absent manifest error, be final and binding
            on all parties.

        Section 7.15       REIT Status.

         

        (a)           KREF Holdings shall not take any action that
            results in the Issuer failing to qualify as a Qualified REIT Subsidiary or other disregarded entity of KREF Sub-REIT for U.S. federal income tax purposes, unless (A) based on an Opinion of Counsel, the Issuer will be treated as a Qualified REIT
            Subsidiary or other disregarded entity of a REIT other than KREF Sub-REIT, or (B) based on an Opinion of Counsel, the Issuer will be treated as a foreign corporation that is not engaged in a trade or business within the United States for U.S.
            federal income tax purposes.

         

        (b)           Without limiting the generality of Section

                7.16, if the Issuer is no longer a Qualified REIT Subsidiary or other disregarded entity of a REIT, prior to the time that:

         

        (i)            any
            Collateral Interest would cause the Issuer to be treated as engaged in a trade or business within the United States for U.S. federal income tax purposes or to become subject to U.S. federal income tax on a net basis,

         

        (ii)          restructuring



            of a Collateral Interest that could cause the Issuer to be treated as engaged in a trade or business within the United States for U.S. federal income tax purposes or to become subject to U.S. federal income tax on a net basis,

         

        (iii)         the
            Issuer would acquire the real property underlying any Collateral Interest pursuant to a foreclosure or deed-in-lieu of foreclosure, or

         

        (iv)         any Real
            Estate Loan is modified in such a manner that could cause the Issuer to be treated as engaged in a trade or business within the United States for U.S. federal income tax purposes or to become subject to U.S. federal income tax on a net basis,

         

        the Issuer will either (x) organize one or more Permitted Subsidiaries and contribute the subject property to such Permitted Subsidiary, (y) contribute
            such Collateral Interest to an existing Permitted Subsidiary, or (z) sell such Collateral Interest in accordance with Section 12.1.

         

        (c)           At the direction of 100% of the Preferred
            Shareholders (including any party that will become the beneficial owner of 100% of the Preferred Shares because of a default under any financing arrangement for which the Preferred Shares are security), the Issuer may operate as a foreign
            corporation that is not engaged in a trade or business within the United States for U.S. federal income tax purposes, provided that (i) the Issuer receives a No
            Entity-Level Tax Opinion; (ii) this Indenture and the Servicing Agreement, as applicable, are amended or supplemented (A) to adopt written tax guidelines governing the Issuer’s origination, acquisition, disposition and modification of Real
            Estate Loans designed to prevent the Issuer from being treated as engaged in a trade or business within the United States for U.S. federal income tax purposes, (B) to form one or more “grantor trusts” to the hold Real Estate Loans and (C) to
            implement any other provisions deemed necessary (as determined by the tax counsel providing the opinion) to prevent the Issuer from being treated as a foreign corporation engaged in a trade or business within the United States for U.S. federal
            income tax purposes or otherwise becoming subject to U.S. federal withholding tax or U.S. federal income tax on a net basis; (iii) the Preferred Shareholder shall pay the administrative and other costs related to the Issuer converting from a
            Qualified REIT Subsidiary to operating as a foreign corporation, including the costs of any opinions and amendments; and (iv) the Preferred Shareholder agrees to pay any ongoing expenses related to the Issuer’s status as a foreign corporation
            not engaged in a trade or business within the United States for U.S. federal income tax purposes, including but not limited to U.S. federal income tax filings required by the Issuer, the “grantor trusts” or any taxable subsidiaries or required
            under FATCA.

        Section 7.16      Permitted Subsidiaries.

         

        Notwithstanding any other provision of this Indenture, the Collateral Manager on behalf of the Issuer shall, following delivery of
            an Issuer Order to the parties hereto, be permitted to sell to a Permitted Subsidiary at any time any Sensitive Asset for consideration consisting entirely of the equity interests of such Permitted Subsidiary (or for an increase in the value of
            equity interests already owned).  Such Issuer Order shall certify that the sale of a Sensitive Asset is being made in accordance with satisfaction of all requirements of this Indenture.  The Custodian shall, upon receipt of a Request for
            Release with respect to a Sensitive Asset, release such Sensitive Asset and shall deliver such Sensitive Asset as specified in such Request for Release.  The following provisions shall apply to all Sensitive Asset and Permitted Subsidiaries:

         

        (a)           For all purposes under this Indenture, any
            Sensitive Asset transferred to a Permitted Subsidiary shall be treated as if it were an asset owned directly by the Issuer.

         

        (b)          Any distribution of Cash by a Permitted
            Subsidiary to the Issuer shall be characterized as Interest Proceeds or Principal Proceeds to the same extent that such Cash would have been characterized as Interest Proceeds or Principal Proceeds if received directly by the Issuer and each
            Permitted Subsidiary shall cause all proceeds of and collections on each Sensitive Asset owned by such Permitted Subsidiary to be deposited into the Payment Account.

         

        (c)           To the extent applicable, the Issuer shall form
            one or more Securities Accounts with the Securities Intermediary for the benefit of each Permitted Subsidiary and shall, to the extent applicable, cause Sensitive Asset to be credited to such Securities Accounts.

         

        (d)          Notwithstanding the complete and absolute
            transfer of a Sensitive Asset to a Permitted Subsidiary, the ownership interests of the Issuer in a Permitted Subsidiary or any property distributed to the Issuer by a Permitted Subsidiary shall be treated as a continuation of its ownership of
            the Sensitive Asset that was transferred to such Permitted Subsidiary (and shall be treated as having the same characteristics as such Sensitive Asset).

         

          

        
          -132-

          
            


        

        (e)           If the Special Servicer on behalf of the
            Trustee, or any other authorized party takes any action under this Indenture to sell, liquidate or dispose of all or substantially all of the Collateral, the Issuer (or the Collateral Manager on its behalf) shall cause each Permitted Subsidiary
            to sell each Sensitive Asset and all other Collateral held by such Permitted Subsidiary and distribute the proceeds of such sale, net of any amounts necessary to satisfy any related expenses and tax liabilities, to the Issuer in exchange for
            the equity interest in such Permitted Subsidiary held by the Issuer.

         

        Section 7.17       Repurchase Requests.

         

        If the Issuer, the Trustee, the Note Administrator, the Collateral Manager, the Servicer or the Special Servicer receives any
            request or demand that a Collateral Interest be repurchased or replaced arising from any Material Breach of a representation or warranty made with respect to such Collateral Interest or any Material Document Defect (any such request or demand,
            a “Repurchase Request”) or a withdrawal of a Repurchase Request from any Person other than the Servicer or Special Servicer, then the Collateral Manager (on behalf of
            the Issuer), the Trustee or the Note Administrator, as applicable, shall promptly forward such notice of such Repurchase Request or withdrawal of a Repurchase Request, as the case may be, to the Servicer (if related to a performing Real Estate
            Loan) or Special Servicer, and include the following statement in the related correspondence:  “This is a “Repurchase Request/withdrawal of a Repurchase Request” under Section 3.19 of the Servicing Agreement relating to KREF 2018-FL1 Ltd. and
            KREF 2018-FL1 LLC, requiring action from you as the “Repurchase Request Recipient” thereunder.”  Upon receipt of such Repurchase Request or withdrawal of a Repurchase Request by the Collateral Manager, Servicer or Special Servicer pursuant to
            the prior sentence, the Servicer or the Special Servicer, as applicable, shall be deemed to be the Repurchase Request Recipient in respect of such Repurchase Request or withdrawal of a Repurchase Request, as the case may be, and shall be
            responsible for complying with the procedures set forth in Section 3.19 of the Servicing Agreement with respect to such Repurchase Request.

         

        Section 7.18       Servicing of Real Estate Loans and Control of Servicing Decisions.

         

        The Real Estate Loans will be serviced by the Servicer or, with respect to Specially Serviced Loans, the Special Servicer, in each
            case pursuant to the Servicing Agreement, subject to the consultation, consent and direction rights of the Collateral Manager, as set forth in the Servicing Agreement, subject to those conditions, restrictions or termination events expressly
            provided therein.  Nothing in this Indenture shall be interpreted to limit in any respect the rights of the Collateral Manager under the Servicing Agreement and none of the Issuer, Co-Issuer, Note Administrator and Trustee shall take any action
            under the Indenture inconsistent with the Collateral Manager’s rights set forth under the Servicing Agreement.

            from registration under the Securities Act, the Exchange Act or the 1940 Act (including, without limitation, (A) to prevent any Class of Notes from being considered an “ownership interest” under the Volcker Rule or (B) to prevent the Issuer or
            the Co-Issuer from being considered a “covered fund” under the Volcker Rule) or to remove restrictions on resale and transfer to the extent not required thereunder;

         

          

      

      
        -134-

            or other disregarded entity of a REIT for U.S. federal income tax purposes or from otherwise being treated as a foreign corporation engaged in a trade or business within the United States for U.S. federal income tax purposes, or to prevent the
            Issuer, the Holders of the Notes, the Holders of the Preferred Shares, or the Trustee from being subject to withholding or other taxes, fees or assessments or from otherwise being subject to U.S. federal, state, local or foreign income or

        (ix)          amend or
            supplement any provision of this Indenture to the extent necessary to maintain the then-current ratings assigned to the Notes;

        

        

        (x)           accommodate




            the settlement of the Notes in book-entry form through the facilities of DTC, Euroclear, Clearstream, Luxembourg or otherwise;

        

        

        (xi)         authorize

            otherwise accommodate any changes to the U.S. Risk Retention Rules or the EU Risk Retention Laws (including such changes as may be required by the Securitization Regulation), as applicable;

        

        

        (xiii)        reduce
            the minimum denominations required for transfer of the Notes;

            provisions of this Indenture with respect to reimbursement of Nonrecoverable Interest Advances if (a) the Collateral Manager determines that the commercial mortgage securitization industry standard for such provisions has changed, in order to
            conform to such industry standard and (b) such modification does not adversely affect the status of Issuer for U.S. federal income tax purposes, as evidenced by an Opinion of Counsel;

        

        

        (xv)         modify
            the procedures set forth in this Indenture relating to compliance with Rule 17g-5 of the Exchange Act; provided that the change would not materially increase the obligations of the Collateral Manager, the Note Administrator, the Trustee, any paying agent, the Servicer or the Special Servicer (in
            each case, without such party’s consent) and would not adversely affect in any material respect the interests of any Noteholder or Holder of the Preferred Shares; provided,
            further, that the Collateral Manager must provide a copy of any such amendment to the 17g-5 Information Provider for posting to the Rule 17g-5 Website and

          -135-

          
            


        

        (xvi)       at the
            direction of 100% of the holders of the Preferred Shares (including any party that shall become the beneficial owner of 100% of the Preferred Shares because of a default under any financing arrangement for which the Preferred Shares are
            security), modify the provisions of this Indenture to adopt restrictions provided by tax counsel in order to prevent the Issuer from being treated as a foreign corporation that is engaged in a trade or business within the United States for U.S.
            federal income tax purposes or otherwise become subject to U.S. federal withholding tax or U.S. federal income tax on a net basis;

        

        

        (xvii)       make such
            changes (including the removal and appointment of any listing agent, transfer agent, paying agent or other additional registrar in Ireland) as will be necessary or advisable in order for the Offered Notes to be or to remain listed on an
            exchange, including The Irish Stock Exchange plc trading as Euronext Dublin, and otherwise to amend the Indenture to incorporate any changes required or requested by governmental authority, stock exchange authority, listing agent, transfer
            agent, paying agent or additional registrar for the Notes in connection therewith; and

        

        

        (xviii)      make any
            change to any other provisions with respect to matters or questions arising under this Indenture; provided that the required action will not adversely
            affect in any material respect the interests of any Noteholder not consenting thereto, as evidenced by (A) an Opinion of Counsel or (B) satisfaction of the Rating Agency Condition.

        

        

        The Note Administrator and Trustee are each hereby authorized to join in the execution of any such supplemental indenture and to make any further
          appropriate agreements and stipulations which may be therein contained, but the Note Administrator and Trustee shall not be obligated to enter into any such supplemental indenture which affects the Note Administrator’s or Trustee’s own rights,
          duties, liabilities or immunities under this Indenture or otherwise, except to the extent required by law.

        

        

        (b)          Notwithstanding Section 8.1(a) or any other provision of this Indenture, without prior notice to, and without the consent of the Holders of any Notes or any Preferred
            Shareholders, and without satisfaction of the Rating Agency Condition, the Issuer, the Co-Issuer, when authorized by Board Resolutions of the Co-Issuers, the Trustee, the Advancing Agent and the Note Administrator, may enter into one or more
            indentures supplemental hereto, in form satisfactory to the Trustee and the Note Administrator, for any of the following purposes:

        

        

        (i)           conform
            this Indenture to the provisions described in the Offering Memorandum (or any supplement thereto); and

        

        

        (ii)           to
            correct any defect or ambiguity in this Indenture in order to address any manifest error, omission or mistake in any provision of this Indenture.

        

        

        
          -136-

          
            


        

        Additionally, at the direction of the Collateral Manager and without the consent of the Noteholders, the Issuer, the Co-Issuer, the
            Note Administrator, the Advancing Agent and the Trustee shall enter into a supplemental indenture to provide for the Notes of each Class to bear interest based on an industry benchmark rate selected by the Collateral Manager and generally
            accepted in the financial markets as the sole or predominant replacement benchmark to LIBOR (the “Successor Benchmark Rate”) plus a Successor Benchmark Spread
            Adjustment from and after a Payment Date specified in such supplemental indenture; provided that no such supplemental indenture shall become effective unless the
            Rating Agency Condition has been satisfied with respect thereto.  In no event shall the Issuer, the Co-Issuer, the Note Administrator, the Advancing Agent or the Trustee be liable for entering into such supplemental indenture without the
            affirmative consent of any Noteholders.

        

        

        (c)          In the event that any or all restrictions and/or limitations under the Regulation RR or European Union laws or regulations relating to risk retention requirements in securitization transaction
              are withdrawn, repealed or modified to be less restrictive on the Sponsor, at the request of the Sponsor and, in the case of the EU Risk Retention Laws, the Retention Holder, the Issuer, the Co-Issuer, the Trustee and the Note Administrator
              agree to modify any corresponding terms of this Indenture in accordance with Section 8.1(a)(xii) to reflect any such withdrawal, repeal or modification.

        

        

        Section 8.2         Supplemental Indentures with Consent of Securityholders.

        

        

        Except as set forth below, the Note Administrator, the Advancing Agent, the Trustee and the Co‐Issuers may enter into one or more
            indentures supplemental hereto to add any provisions to, or change in any manner or eliminate any of the provisions of, this Indenture or modify in any manner the rights of the Holders of any Class of Notes or the Preferred Shares under this
            Indenture only (x) with the written consent of the Holders of at least Majority in Aggregate Outstanding Amount of the Notes of each Class materially and adversely affected thereby (excluding any Notes owned by the Seller, the Collateral
            Manager or any of their Affiliates) and the Holder of Preferred Shares if materially and adversely affected thereby, by Act of said Securityholders delivered to the Trustee, the Note Administrator, the Advancing Agent and the Co-Issuers, and
            (y) subject to satisfaction of the Rating Agency Condition, notice of which may be in electronic form.  The Note Administrator shall provide (x) fifteen (15) Business Days’ notice of such change to the Holders of each Class of Notes and the
            Holder of the Preferred Shares, requesting notification by such Noteholders and Holders of the Preferred Shares if any such Noteholders or Holders of the Preferred Shares would be materially and adversely affected by the proposed supplemental
            indenture and (y) following such initial fifteen (15) Business Day period, the Note Administrator shall provide an additional fifteen (15) Business Days’ notice to any holder of Notes or Preferred Shares that did not respond to the initial
            notice.  Unless the Note Administrator is notified (after giving such initial fifteen (15) Business Days’ notice and a second fifteen (15) Business Days’ notice, as applicable) by Holders of at least a Majority in Aggregate Outstanding Amount
            of the Notes (excluding any Notes held by the Seller, the Collateral Manager or any of their Affiliates or by any accounts managed by them) of any Class that such Class of Notes or a Majority of Preferred Shareholders will be materially and
            adversely affected by the proposed supplemental indenture (and upon receipt of an Officer’s Certificate of the Collateral Manager), the interests of such Class and the interests of the Preferred Shares will be deemed not to be materially and
            adversely affected by such proposed supplemental indenture and the Trustee will be permitted to enter into such supplemental indenture.  Such determinations shall be
            conclusive and binding on all present and future Noteholders.  The consent of the Holders of the Preferred Shares shall be binding on all present and future Holders of the Preferred Shares.

         

          

        
          -137-

          
            


        

        Without the consent of (x) all of the Holders of each Outstanding Class of Notes materially adversely affected and (y) all of the
            Holders of the Preferred Shares materially adversely affected thereby, no supplemental indenture may:

        

        

        (a)          change the Stated Maturity Date of the principal
            of or the due date of any installment of interest on any Note, reduce the principal amount thereof or the Note Interest Rate thereon or the Redemption Price with respect to any Note, change the date of any scheduled distribution on the
            Preferred Shares, or the Redemption Price with respect thereto, change the earliest date on which any Note may be redeemed at the option of the Issuer, change the provisions of this Indenture that apply proceeds of any Collateral to the payment
            of principal of or interest on Notes or of distributions to the Preferred Share Paying Agent for the payment of distributions in respect of the Preferred Shares or change any place where, or the coin or currency in which, any Note or the
            principal thereof or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity Date thereof (or, in the case of redemption, on or after the applicable Redemption
            Date);

        

        

        (b)         reduce the percentage of the Aggregate
            Outstanding Amount of Holders of Notes of each Class or the Notional Amount of Preferred Shares of the Holders thereof whose consent is required for the authorization of any such supplemental indenture or for any waiver of compliance with
            certain provisions of this Indenture or certain Defaults hereunder or their consequences provided for in this Indenture;

        

        

        (c)           impair or adversely affect the Collateral
            except as otherwise permitted in this Indenture;

        

        

        (d)          permit the creation of any lien ranking prior to
            or on a parity with the lien of this Indenture with respect to any part of the Collateral or terminate such lien on any property at any time subject hereto or deprive the Holder of any Note, or the Holder of any Preferred Share as an indirect
            beneficiary, of the security afforded to such Holder by the lien of this Indenture;

        

        

        (e)         reduce the percentage of the Aggregate
            Outstanding Amount of Holders of Notes of each Class whose consent is required to request the Trustee to preserve the Collateral or rescind any election to preserve the Collateral pursuant to Section 5.5 or to sell or liquidate the Collateral pursuant to Section 5.4 or 5.5 hereof;

        

        

        (f)          modify any of the provisions of this Section 8.2, except to increase any percentage of Outstanding Notes whose holders’ consent is required for any such action or to provide that other provisions of this
            Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Note affected thereby;

        

        

        (g)          modify the definition of the term “Outstanding”
            or the provisions of Section 11.1(a) or Section 13.1 hereof;

        

        

        
          -138-

          
            


        

        (h)         modify any of the provisions of this Indenture in
            such a manner as to affect the calculation of the amount of any payment of interest on or principal of any Note on any Payment Date or of distributions to the Preferred Share Paying Agent for the payment of distributions in respect of the
            Preferred Shares on any Payment Date (or any other date) or to affect the rights of the Securityholders to the benefit of any provisions for the redemption of such Securities contained herein;

        

        

        (i)           modify any of the provisions of this Indenture
            in such a manner as to affect the requirement that the Issuer be treated as a Qualified REIT Subsidiary or other disregarded entity of a REIT for U.S. federal income tax purposes;

        

        

        (j)           reduce the permitted minimum denominations of
            the Notes below the minimum denomination necessary to maintain an exemption from the registration requirements of the Securities Act or the 1940 Act; or

        

        

        (k)          modify any provisions regarding non- recourse or
            non-petition covenants with respect to the Issuer and the Co-Issuer.

        

        

        The Trustee and Note Administrator shall be entitled to rely upon an Officer’s Certificate of the Issuer (or the Collateral Manager
            on its behalf) in determining whether or not the Securityholders would be materially or adversely affected by such change (after giving notice of such change to the Securityholders).  Such determination shall be conclusive and binding on all
            present and future Securityholders.  Neither the Trustee nor the Note Administrator shall be liable for any such determination made in good faith.

        

        

        Section 8.3        Execution of Supplemental Indentures.

        

        

        In executing or accepting the additional trusts created by any supplemental indenture permitted by this Article 8 or the modifications thereby of the trusts created by this Indenture, the Note Administrator and Trustee shall be entitled to receive, and shall be fully protected in relying
            upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent thereto have been satisfied (which Opinion of Counsel may rely upon an
            Officer’s Certificate as to whether or not the Securityholders would be materially and adversely affected by such supplemental indenture).  The Note Administrator and Trustee may, but shall not be obligated to, enter into any such supplemental
            indenture which affects its own rights, duties or immunities under this Indenture or otherwise.

        

        

        The Sponsor’s written consent shall be required prior to any amendment to this Indenture by which the Sponsor is adversely affected.

        

        

        The Servicer and Special Servicer will not be bound to follow any amendment or supplement to this Indenture that affect their
            respective rights and obligations unless the Servicer or Special Servicer, as applicable, gives written consent to the Note Administrator, the Trustee and the Issuer to such amendment.  The Issuer, the Trustee and the Note Administrator shall
            give written notice to the Servicer and Special Servicer of any amendment made to this Indenture pursuant to its terms.  In addition, the Servicer and Special Servicer’s written consent shall be required prior to any amendment to this Indenture
            by which it is adversely affected.

        

        

        
          -139-

          
            


        

        The Collateral Manager will be bound to follow any amendment or supplement to this Indenture of which it has received written notice
            at least ten (10) Business Days prior to the execution and delivery of such amendment or supplement; provided, however, that with respect to any amendment or supplement to this Indenture which may, in the judgment of the Collateral Manager adversely affect the Collateral Manager, the Collateral Manager, as applicable, shall not
            be bound (and the Issuer agrees that it will not permit any such amendment to become effective) unless the Collateral Manager, as applicable, gives written consent to the Note Administrator, the Trustee and the Issuer to such amendment.  The
            Issuer, the Trustee and the Note Administrator shall give written notice to the Collateral Manager, the Servicer and the Special Servicer of any amendment made to this Indenture pursuant to its terms.  In addition, the Collateral Manager’s
            written consent shall be required prior to any amendment to this Indenture by which it is adversely affected.

        

        

        At the cost of the Issuer, the Note Administrator shall provide to each Noteholder, each holder of Preferred Shares and, for so long
            as any Class of Notes shall remain Outstanding and is rated, the Note Administrator shall provide to the 17g-5 Information Provider and the Rating Agencies a copy of any proposed supplemental indenture at least fifteen (15) Business Days prior
            to the execution thereof by the Note Administrator, and following execution shall provide to the 17g-5 Information Provider and the Rating Agencies a copy of the executed supplemental indenture.

        

        

        The Trustee shall not enter into any such supplemental indenture (i) if such action would adversely affect the tax treatment of the
            Holders of the Notes as described in the Offering Memorandum under the heading “Certain U.S. Federal Income Tax Considerations” to any material extent or otherwise cause any of the statements described in the Offering Memorandum under the
            heading “Certain U.S. Federal Income Tax Considerations” to be inaccurate or incorrect to any material extent, and (ii) unless the Trustee and the Note Administrator has received an Opinion of Counsel from Dechert LLP, Hunton Andrews Kurth LLP
            or other nationally recognized U.S. tax counsel experienced in such matters that the proposed supplemental indenture will not cause the Issuer to be treated as a foreign corporation that is engaged in a trade or business within the United
            States for U.S. federal income tax purposes.  The Trustee and the Note Administrator shall be entitled to rely upon (i) the receipt of notice from the Rating Agencies or the Requesting Party, which may be in electronic form, that the Rating
            Agency Condition has been satisfied and (ii) receipt of an Opinion of Counsel forwarded to the Trustee and Note Administrator certifying that, following provision of notice of such supplemental indenture to the Noteholders and holders of the
            Preferred Shares, that the Securityholders would not be materially and adversely affected by such supplemental indenture.  Such determination shall be conclusive and binding on all present and future Securityholders.  Neither the Trustee nor
            the Note Administrator shall be liable for any such determination made in good faith and in reliance upon such Opinion of Counsel, as the case may be.

        

        

        It shall not be necessary for any Act of Securityholders under this Section





                8.3 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

        

        

        
          -140-

          
            


        

        Promptly after the execution by the Issuer, the Co-Issuer, the Note Administrator and the Trustee of any supplemental indenture
            pursuant to this Section 8.3, the Note Administrator, at the expense of the Issuer, shall mail to the Securityholders, the Preferred Share Paying Agent, the Servicer,
            the Special Servicer, the Sponsor and, so long as the Notes are Outstanding and so rated, the Rating Agencies a copy thereof based on an outstanding rating.  Any failure of the Trustee and the Note Administrator to publish or mail such notice,
            or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

        Upon the execution of any supplemental indenture under this Article



                8, this Indenture shall be modified in accordance therewith, such supplemental indenture shall form a part of this Indenture for all purposes and every Holder of Notes theretofore and thereafter authenticated and delivered
            hereunder, and every Holder of Preferred Shares, shall be bound thereby.

        

        

        Section 8.5         Reference in Notes to Supplemental Indentures.

        

        

        Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article 8 may, and if required by the Note Administrator shall, bear a notice in form approved by the Note Administrator as to any matter provided for in such supplemental indenture.  If the
            Issuer and the Co-Issuer shall so determine, new Notes, so modified as to conform in the opinion of the Note Administrator and the Issuer and the Co-Issuer to any such supplemental indenture, may be prepared and executed by the Issuer and the
            Co-Issuer and authenticated and delivered by the Note Administrator in exchange for Outstanding Notes.  Notwithstanding the foregoing, any Note authenticated and delivered hereunder shall be subject to the terms and provisions of this
            Indenture, and any supplemental indenture.

        Section 9.1        Clean-up Call; Tax Redemption; Optional Redemption; and Auction Call Redemption.

        

        

        (a)          The Notes shall be redeemed by the Issuer and the
            Co-Issuer, as applicable, at the direction of the Collateral Manager delivered to the Issuer, the Note Administrator and the Trustee (such redemption, a “Clean-up Call”),





            in whole but not in part, at a price equal to the applicable Redemption Prices on any Payment Date (the “Clean-up Call Date”) on or after the Payment Date on which the
            Aggregate Outstanding Amount of the Offered Notes (excluding Deferred Interest amounts) has been reduced to 10% or less of the Aggregate Outstanding Amount of the Offered Notes on the Closing Date; provided that that the funds available to be used for such Clean-up Call will be sufficient to pay the Total Redemption Price.  Disposition of Collateral in connection with a Clean-up Call may include sales
            of Collateral to more than one purchaser, including by means of sales of participation interests in one or more Real Estate Loans to more than one purchaser.

        (b)          The Notes shall be redeemable by the Issuer and
            the Co-Issuer, as applicable, in whole but not in part, at the written direction of a Majority of Preferred Shareholders delivered to the Issuer, the Note Administrator, the Preferred Share Paying Agent and the Trustee, on the Payment Date (the
            “Tax Redemption Date”) following the occurrence of a Tax Event if the Tax Materiality Condition is satisfied at a price equal to the applicable Redemption Prices (such
            redemption, a “Tax Redemption”); provided that that the funds available to be used for
            such Tax Redemption will be sufficient to pay the Total Redemption Price.  Upon the receipt of such written direction of a Tax Redemption, the Note Administrator shall provide written notice thereof to the Securityholders and the Rating
            Agencies.  Any sale or disposition of a Collateral Interest by the Trustee in connection with a Tax Redemption shall be performed upon Issuer Order by the Collateral Manager on behalf of the Issuer.

        

        

        (c)          The Notes shall be redeemable by the Issuer and
            the Co-Issuer, as applicable, in whole but not in part, in whole but not in part and without payment of any penalty or premium, at a price equal to the applicable Redemption Prices, on any Payment Date after the end of the Non-call Period, at
            the written direction of a Majority of the Preferred Shareholders to the Issuer, the Note Administrator and the Trustee (such redemption, an “Optional Redemption”); provided, however,
            that the funds available to be used for such Optional Redemption will be sufficient to pay the Total Redemption Price.  Notwithstanding anything herein to the contrary, the Issuer shall not sell any Collateral Interest to any Affiliate other
            than the Retention Holder in connection with an Optional Redemption.

        

        

        Notwithstanding anything herein to the contrary in this Indenture, in the case of an Optional Redemption, if the Holder of the
            Preferred Shares and/or one or more Affiliates thereof own 100% of one or more of the most junior Classes of Notes, such Holder(s) may elect to exchange such Notes and the Preferred Shares for all of the remaining Collateral Interests and other
            assets of the Issuer, in lieu of the Issuer paying such Holder(s) the Redemption Price for such Securities.

        

        

        (d)          The Notes shall be redeemable by the Issuer and
            the Co-Issuer, as applicable, in whole but not in part, at a price equal to the applicable Redemption Prices, on any Payment Date occurring in January, April, July or October in each year, beginning on the Payment Date occurring in December
            2028, upon the occurrence of a Successful Auction, as defined in, and pursuant to the procedures set forth in, Section 3.18(b) of the Servicing Agreement (such redemption, an “Auction



                Call Redemption”).

        

        

        (e)          The election by the Collateral Manager to redeem
            the Notes pursuant to a Clean-up Call shall be evidenced by an Officer’s Certificate from the Collateral Manager directing the Note Administrator to pay to the Paying Agent the Redemption Price of all of the Notes to be redeemed from funds in
            the Payment Account in accordance with the Priority of Payments.  In connection with a Tax Redemption, the occurrence of a Tax Event and satisfaction of the Tax Materiality Condition and the election by a Majority of Preferred Shareholders to
            redeem the Notes pursuant to a Tax Redemption shall be evidenced by an Officer’s Certificate from the Collateral Manager certifying that such conditions for a Tax Redemption have occurred.  The election by a Majority of Preferred Shareholders
            to redeem the Notes pursuant to an Optional Redemption shall be evidenced by an Officer’s Certificate from the Collateral Manager certifying that the conditions for an Optional Redemption have occurred.

        (f)           A redemption pursuant to Section 9.1(a), 9.1(b) or 9.1(c) shall not occur unless (i) at least five (5) Business Days before the scheduled Redemption Date, (A) the Collateral Manager shall have furnished to the Trustee and the Note Administrator evidence (in a
              form reasonably satisfactory to the Trustee and the Note Administrator) that the Collateral Manager, on behalf of the Issuer, has entered into a binding agreement or agreements with one or more financial institutions whose long-term unsecured
              debt obligations (other than such obligations whose rating is based on the credit of a Person other than such institution) have a credit rating from Moody’s at least equal to the highest rating of any Notes then Outstanding or whose
              short-term unsecured debt obligations have a credit rating of “P-1” or higher by Moody’s (as long as the term of such agreement is ninety (90) days or less), to sell
              (directly or by participation or other arrangement) all or part of the Collateral not later than the Business Day immediately preceding the scheduled Redemption Date, (B) the Rating Agency Condition has been satisfied with respect to the
              applicable method of redemption, (C) the Collateral Manager shall have furnished to the Trustee and the Note Administrator evidence (in a form reasonably satisfactory to the Trustee and the Note Administrator) that the Collateral Manager, on
              behalf of the Issuer, has entered into a binding agreement or agreements with the Retention Holder (or an Affiliate or agent thereof) to sell (directly or by participation or other arrangement) all or part of the Collateral not later than the
              scheduled Redemption Date, or (D) KREF Holdings (or an Affiliate or agent thereof) has priced but not yet closed another securitization transaction, and (ii) the related Sale Proceeds pursuant to clause (i)(A) or clause (i)(C), or the net
              proceeds pursuant to clause (i)(D), as applicable, (in immediately available funds), together with all other available funds (including proceeds from the sale of the Collateral, Eligible Investments maturing on or prior to the scheduled
              Redemption Date, all amounts in the Accounts and available Cash), shall be an aggregate amount sufficient to pay all amounts, payments, fees and expenses in accordance with the Priority of Payments due and owing on such Redemption Date.

        

        

        Section 9.2        Notice of Redemption.

        

        

        (a)         In connection with a Clean-up Call pursuant to Section 9.1(a), a Tax Redemption pursuant to Section 9.1(b), an Optional Redemption pursuant
            to Section 9.1(c), or an Auction Call Redemption pursuant to Section 9.1(d), the Note
            Administrator shall set the applicable Record Date ten (10) Business Days prior to the proposed Redemption Date.  The Note Administrator shall deliver to the Rating Agencies any notice received by it from the Issuer or the Special Servicer of
            such proposed Redemption Date, the applicable Record Date, the principal amount of Notes to be redeemed on such Redemption Date and the Redemption Price of such Notes in accordance with Section 9.1.

        

        

        (b)          Any such notice of an Optional Redemption,
            Clean-up Call or Tax Redemption may be withdrawn by the Issuer and the Co-Issuer at the direction of the Collateral Manager up to the second Business Day prior to the scheduled Redemption Date by written notice to the Note Administrator, the
            Trustee, the Preferred Share Paying Agent, the Servicer, the Special Servicer, the Operating Advisor and each Holder of Notes to be redeemed.  The failure of any Optional Redemption, Clean-up Call or Tax Redemption that is withdrawn in
            accordance with this Indenture shall not constitute an Event of Default.

        Section 9.3         Notice of Redemption or Maturity.

        

        

        Any sale or disposition of a Collateral Interest by the Trustee in connection with an Optional Redemption, Clean-up Call, Tax
            Redemption or Auction Call Redemption shall be performed upon Issuer Order by the Collateral Manager on behalf of the Issuer, and the Trustee shall have no responsibility or liability therefore.  Notice of redemption (or a withdrawal thereof)
            or Clean-up Call pursuant to Section 9.1 or the Maturity of any Notes shall be given by first class mail, postage prepaid, mailed not less than ten (10) Business Days
            (or, where the notice of an Optional Redemption, a Clean-up Call or a Tax Redemption is withdrawn pursuant to Section 9.2(b), four (4) Business Days (or promptly
            thereafter upon receipt of written notice, if later)) prior to the applicable Redemption Date or Maturity, to (unless the Note Administrator agrees to a shorter notice period) the Collateral Manager, the Trustee, the Servicer, the Special
            Servicer, the Preferred Share Paying Agent, the Rating Agencies, and each Securityholder to be redeemed, at its address in the Notes Register.

        

        

        All notices of redemption shall state:

        

        

        (a)          the applicable Redemption Date;

        

        

        (b)          the applicable Redemption Price;

        

        

        (c)          that all the Notes are being paid in full and
            that interest on the Notes shall cease to accrue on the Redemption Date specified in the notice; and

        

        

        (d)          the place or places where such Notes to be
            redeemed in whole are to be surrendered for payment of the Redemption Price which shall be the office or agency of the Paying Agent as provided in Section 7.2.

        

        

        Notice of redemption shall be given by the Issuer and Co-Issuer, or at their request, by the Note Administrator in their names, and
            at the expense of the Issuer.  Failure to give notice of redemption, or any defect therein, to any Holder of any Note shall not impair or affect the validity of the redemption of any other Notes.

        

        

        Section 9.4        Notes Payable on Redemption Date.

        

        

        Notice of redemption having been given as aforesaid, the Notes to be redeemed shall, on the Redemption Date, become due and payable
            at the Redemption Price therein specified, and from and after the Redemption Date (unless the Issuer shall Default in the payment of the Redemption Price and accrued interest thereon) the Notes shall cease to bear interest on the Redemption
            Date.  Upon final payment on a Note to be redeemed, the Holder shall present and surrender such Note at the place specified in the notice of redemption on or prior to such Redemption Date; provided, however, that if there is delivered to
            the Issuer, the Co-Issuer, the Note Administrator and the Trustee such security or indemnity as may be required by them to hold each of them harmless and an undertaking thereafter to surrender such Note, then, in the absence of notice to the
            Issuer, the Note Administrator and the Trustee that the applicable Note has been acquired by a bona fide purchaser, such final payment shall be made without presentation or surrender.  Payments of interest on the Notes so to be redeemed whose
            Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Notes, or one or more predecessor Notes, registered as such at the close of business on the relevant Record Date according to the terms and provisions of Section 2.7(f).

        

        

        
          -144-

          
            


        

        If any Note called for redemption shall not be paid upon surrender thereof for redemption, the principal thereof shall, until paid,
            bear interest from the Redemption Date at the applicable Note Interest Rate for each successive Interest Accrual Period the Note remains Outstanding.

        

        

        Section 9.5        Mandatory Redemption.

        

        

        (a)          If either of the Note Protection Tests is not
            satisfied as of the most recent Measurement Date, one or more Classes of Notes shall be redeemed (a “Mandatory Redemption”), first from Interest Proceeds as set forth
            in Section 11.1(a)(i)(12) in an amount necessary, and only to the extent necessary, for such Note Protection Test to be satisfied.  On or promptly after such
            Mandatory Redemption, the Issuer shall certify or cause to be certified to the Rating Agencies and the Note Administrator whether the Note Protection Tests have been satisfied.

            the Note Administrator may demand payment or delivery of, and shall receive and collect, directly and without intervention or assistance of any fiscal agent or other intermediary, all amounts and other property payable to or receivable by the
            Note Administrator pursuant to this Indenture, including all payments due on the Collateral in accordance with the terms and conditions of such Collateral.  The Note Administrator shall segregate and hold all such amounts and property received
            by it in an Eligible Account in trust for the Secured Parties, and shall apply such amounts as provided in this Indenture.  Any Indenture Account may include any number of subaccounts deemed necessary or appropriate by the Trustee for
            convenience in administering sub account.

            Interests and Eligible Investments to an account in its own name for the benefit of the Secured Parties designated as the “Custodial Account.”

        

        

        Section 10.2       Reinvestment Account.

        

        

        (a)         The Note Administrator shall, on or prior to the
            Closing Date, establish a single, segregated trust account which shall be designated as the “Reinvestment Account,” which shall be held in trust in the name of the
            Note Administrator for the benefit of the Secured Parties and over which the Note Administrator shall have exclusive control and the sole right of withdrawal; provided,


            however, that the Note Administrator shall only withdraw such amounts as directed by the Issuer or the Collateral Manager on behalf of the Issuer.  All amounts
            credited to the Reinvestment Account pursuant to Section 11.1(a)(ii) of this Indenture or otherwise shall be held by the Note Administrator as part of the Collateral
            and shall be applied to the purposes herein provided.

        

        

        
          -145-

          
            


        

        (b)         The Note Administrator agrees to give the Issuer
            and the Collateral Manager prompt notice if it becomes aware that the Reinvestment Account or any funds on deposit therein, or otherwise to the credit of the Reinvestment Account, becomes subject to any writ, order, judgment, warrant of
            attachment, execution or similar process.  The Issuer shall have no legal, equitable or beneficial interest in the Reinvestment Account other than in accordance with the Priority of Payments.  The Reinvestment Account shall remain at all times
            an Eligible Account.

        

        

        (c)        The Collateral Manager, on behalf of the Issuer,
            may direct the Note Administrator to, and upon such direction the Note Administrator shall, invest all funds in the Reinvestment Account in Eligible Investments designated by the Collateral Manager, and in accordance with Section 11.2.  All interest and other income from such investments shall be deposited in the Reinvestment Account, any gain realized from such investments shall be
            credited to the Reinvestment Account, and any loss resulting from such investments shall be charged to the Reinvestment Account.  The Note Administrator shall not in any way be held liable (except as a result of negligence, willful misconduct
            or bad faith) by reason of any insufficiency of such Reinvestment Account resulting from any loss relating to any such investment, except with respect to investments in obligations of the Note Administrator or any Affiliate thereof.  If the
            Note Administrator does not receive written investment instructions from an Authorized Officer of the Collateral Manager, funds in the Reinvestment Account shall be held uninvested.

        

        

        (d)         Amounts in the Reinvestment Account shall remain
            in the Reinvestment Account (or invested in Eligible Investments) until the earlier of (i) the time the Collateral Manager instructs the Note Administrator in writing to transfer any such amounts (or related Eligible Investments) to the Payment
            Account, (ii) the time the Collateral Manager notifies the Note Administrator in writing that such amounts (or related Eligible Investments) are to be applied to the acquisition of Reinvestment Collateral Interests in accordance with Section 12.2(a) and (iii) the first Business Day after the last day of the Reinvestment Period.  Upon receipt of notice pursuant to clause (i) above and on the date
            described in clause (iii) above, the Note Administrator shall transfer the applicable amounts (or related Eligible Investments) to the Payment Account, in each case for application on the next Payment Date pursuant to Section 11.1(a)(ii) as Principal Proceeds.

        

        

        (e)        During the Reinvestment Period, the Collateral
            Manager on behalf of the Issuer may, by notice to the Note Administrator, direct the Note Administrator to, and upon receipt of such notice the Note Administrator shall, reinvest amounts (and related Eligible Investments) credited to the
            Reinvestment Account in Real Estate Loans and Pari Passu Participations selected by the Collateral Manager as permitted under and in accordance with the requirements of Article
                12 and such notice.  The Note Administrator shall be entitled to conclusively rely on such notice and shall not be required to make any determination as to whether any loans or participations satisfy the Eligibility Criteria, the
            Reinvestment Criteria or the Acquisition and Disposition Requirements.

        Section 10.3       Payment Account.

        

        

        (a)         The Note Administrator shall, on or prior to the
            Closing Date, establish a single, segregated trust account which shall be designated as the “Payment Account,” which shall be held in trust for the benefit of the Secured Parties and over which the Note Administrator shall have exclusive
            control and the sole right of withdrawal.  Any and all funds at any time on deposit in, or otherwise to the credit of, the Payment Account shall be held in trust by the Note Administrator, on behalf of the Trustee for the benefit of the Secured
            Parties.  Except as provided in Sections 11.1 and 11.2, the only permitted withdrawal
            from or application of funds on deposit in, or otherwise to the credit of, the Payment Account shall be (i) to pay the interest on and the principal of the Notes and make other payments in respect of the Notes in accordance with their terms and
            the provisions of this Indenture, (ii) to deposit into the Preferred Share Payment Account for distributions to the Preferred Shareholders, (iii) upon Issuer Order, to pay other amounts specified therein, and (iv) otherwise to pay amounts
            payable pursuant to and in accordance with the terms of this Indenture, each in accordance with the Priority of Payments.

        

        

        (b)         The Note Administrator agrees to give the Issuer
            and the Collateral Manager prompt notice if it becomes aware that the Payment Account or any funds on deposit therein, or otherwise to the credit of the Payment Account, becomes subject to any writ, order, judgment, warrant of attachment,
            execution or similar process.  The Issuer shall have no legal, equitable or beneficial interest in the Payment Account other than in accordance with the Priority of Payments.  The Payment Account shall remain at all times an Eligible Account.

        Section 10.5       Expense Reserve Account.

        

        

        (a)          The Note Administrator shall, on or prior to the
            Closing Date, establish a single, segregated trust account which shall be designated as the “Expense Reserve Account,” which shall be held in trust in the name of the
            Note Administrator for the benefit of the Secured Parties and over which the Note Administrator shall have exclusive control and the sole right of withdrawal.  The only permitted withdrawal from or application of funds on deposit in, or
            otherwise standing to the credit of, the Expense Reserve Account shall be to pay (on any day other than a Payment Date), accrued and unpaid Company Administrative Expenses (other than accrued and unpaid expenses and indemnities payable to the
            Collateral Manager under the Collateral Management Agreement); provided that the Collateral Manager shall be entitled (but not required) without liability on its part, to direct the Note Administrator to refrain from making any such payment of a
            Company Administrative Expense on any day other than a Payment Date if, in its reasonable determination, taking into account the Priority of Payments, the payment of such amounts is likely to leave insufficient funds available to pay in full
            each of the items payable prior thereto in the Priority of Payments on the next succeeding Payment Date.  At the direction of the Collateral Manager, amounts credited to the Expense Reserve Account may be applied on or prior to the
            Determination Date preceding the first Payment Date to pay amounts due in connection with the offering of the Notes.  On or after the first Payment Date, any amount remaining in the Expense Reserve Account may, at the election of the Collateral
            Manager, be designated as Interest Proceeds.  On the date on which all or substantially all of the Issuer’s assets have been sold or otherwise disposed of, the Issuer by Issuer Order executed by an Authorized Officer of the Collateral Manager
            shall direct the Note Administrator to, and upon receipt of such Issuer Order, the Note Administrator shall, transfer all amounts on deposit in the Expense Reserve Account to the Payment Account for application pursuant to Section 11.1(a)(i) as Interest Proceeds.

        

        

        
          -147-

          
            


        

        (b)         On each Payment Date, the Collateral Manager may
            designate Interest Proceeds (in an amount not to exceed U.S.$100,000 on such Payment Date) after application of amounts payable pursuant to clauses (1) through (17) of Section
                11.1(a)(i) for deposit into the Expense Reserve Account.

        

        

        (c)          The Note Administrator agrees to give the Issuer
            and the Collateral Manager prompt notice if it becomes aware that the Expense Reserve Account or any funds on deposit therein, or otherwise to the credit of the Expense Reserve Account, becomes subject to any writ, order, judgment, warrant of attachment, execution or similar process.  The Issuer shall have no legal, equitable or beneficial interest in the Expense Reserve Account other than in accordance with the
            Priority of Payments.  The Expense Reserve Account shall remain at all times an Eligible Account.

        

        

        (d)          The Collateral Manager, on behalf of the Issuer,
            may direct the Note Administrator to, and upon such direction the Note Administrator shall, invest all funds in the Expense Reserve Account in Eligible Investments designated by the Collateral Manager as provided in Section 11.2.  All interest and other income from such investments shall be deposited in the Expense Reserve Account, any gain realized from such investments shall be credited to the
            Expense Reserve Account, and any loss resulting from such investments shall be charged to the Expense Reserve Account.  The Note Administrator shall not in any way be held liable (except as a result of negligence, willful misconduct or bad
            faith) by reason of any insufficiency of such Expense Reserve Account resulting from any loss relating to any such investment, except with respect to investments in obligations of the Note Administrator or any Affiliate thereof.  If the Note
            Administrator does not receive written investment instructions from an Authorized Officer of the Collateral Manager, funds in the Expense Reserve Account shall be held uninvested.

        Section 10.7          Interest Advances.

        

        

        (a)          With respect to each Payment Date for which the
            sum of Interest Proceeds and, if applicable, Principal Proceeds, collected during the related Due Period and remitted to the Note Administrator are insufficient to remit the interest due and payable with respect to the Class A Notes, the Class
            A-S Notes and the Class B Notes on such Payment Date as a result of interest shortfalls on the Class A Notes, the Class A-S Notes and the Class B Notes (or the application of interest received on the Class A Notes, the Class A-S Notes and the
            Class B Notes to pay certain expenses in accordance with the terms of the Servicing Agreement) (the amount of such insufficiency, an “Interest Shortfall”), the Note
            Administrator shall provide the Advancing Agent with email notice of such Interest Shortfall no later than the close of business on the Business Day preceding such Payment Date, at the following address: KREFCLO@KKR.com, or such other email
            address as provided by the Advancing Agent to the Note Administrator.  The Note Administrator shall provide the Advancing Agent with additional email notice, prior to any funding of an Interest Advance by the Advancing Agent, of any additional
            interest remittances received by the Note Administrator after delivery of such initial notice that reduces such Interest Shortfall.  No later than 10:00 a.m. (New York time) on the related Payment Date, the Advancing Agent shall advance the
            difference between such amounts (each such advance, an “Interest Advance”) by deposit of an amount equal to such Interest Advance in the Payment Account, subject to a
            determination of recoverability by the Advancing Agent as described in Section 10.7(b), and subject to a maximum limit in respect of any Payment Date equal to the
            lesser of (i) the aggregate of such Interest Shortfalls that would otherwise occur on the Class A Notes, the Class A-S Notes and the Class B Notes and (ii) the aggregate of the interest payments not received in respect of Collateral Interests
            with respect to such Payment Date (including, for such purpose, interest payments received on the Collateral Interests but applied to pay certain expenses in accordance with the terms of the Servicing Agreement).

        

        

        Notwithstanding the foregoing, in no circumstance will the Advancing Agent be required to make an Interest Advance in respect of a
            Collateral Interest to the extent that the aggregate outstanding amount of all unreimbursed Interest Advances would exceed the Aggregate Outstanding Amount of the Offered Notes.  In addition, in no event will the Advancing Agent or Backup
            Advancing Agent be required to advance any payments in respect of interest on any Class of Notes other than the Class A Notes, the Class A-S Notes and the Class B Notes or principal of any Note.  Any Interest Advance made by the Advancing Agent
            with respect to a Payment Date that is in excess of the actual Interest Shortfall for such Payment Date shall be refunded to the Advancing Agent by the Note Administrator on the related Payment Date (or, if such Interest Advance is made prior
            to final determination by the Note Administrator of such Interest Shortfall, on the Business Day of such final determination).

        

        

        The Advancing Agent shall provide the Note Administrator written notice of a determination by the Advancing Agent that a proposed
            Interest Advance would constitute a Nonrecoverable Interest Advance no later than 10:00 a.m. (New York time) on the related Payment Date.  If the Advancing Agent shall fail to make any required Interest Advance by 10:00 a.m. (New York time) on
            the Payment Date upon which distributions are to be made pursuant to Section 11.1(a)(i), the Collateral Manager shall remove the Advancing Agent in its capacity as
            advancing agent hereunder as required under Section 16.5(d) and the Backup Advancing Agent shall be required to make such Interest Advance no later than 11:00 a.m.
            (New York time) on the Payment Date, subject to a determination of recoverability by the Backup Advancing Agent as described in Section 10.7(b).  Based upon available information at the time, the Backup Advancing Agent and the Advancing Agent or the Collateral Manager, as applicable, will provide
            fifteen (15) days prior notice to the Rating Agencies if recovery of a Nonrecoverable Interest Advance would result in an Interest Shortfall on the next succeeding Payment Date.  No later than the close of business on the Determination Date
            related to a Payment Date on which the recovery of a Nonrecoverable Interest Advance would result in an Interest Shortfall, the Backup Advancing Agent and the Advancing Agent or the Collateral Manager, as applicable, will provide the Rating
            Agencies notice of such recovery.

        

        

        
          -149-

          
            


        

        (b)          Notwithstanding anything herein to the contrary,
            neither the Advancing Agent nor the Backup Advancing Agent, as applicable, shall be required to make any Interest Advance unless such Person determines, in its sole discretion, exercised in good faith that such Interest Advance, or such
            proposed Interest Advance, plus interest expected to accrue thereon at the Reimbursement Rate, will not be a Nonrecoverable Interest Advance.  In determining whether any proposed Interest Advance will be, or whether any Interest Advance
            previously made is, a Nonrecoverable Interest Advance, the Advancing Agent or the Backup Advancing Agent, as applicable, will take into account:

        

        

        (i)           amounts
            that may be realized on each Mortgaged Property in its “as is” or then-current condition and occupancy;

        

        

        (ii)          the
            potential length of time before such Interest Advance may be reimbursed and the resulting degree of uncertainty with respect to such reimbursement; and

        

        

        (iii)          the
            possibility and effects of future adverse changes with respect to the Mortgaged Properties, and

        

        

        (iv)          the fact
            that Interest Advances are intended to provide liquidity only and not credit support to the Holders of any Class of Notes entitled thereto.

        

        

        For purposes of any such determination of whether an Interest Advance constitutes or would constitute a Nonrecoverable Interest
            Advance, an Interest Advance will be deemed to be nonrecoverable if the Advancing Agent or the Backup Advancing Agent, as applicable, determines that future Interest Proceeds and Principal Proceeds may be ultimately insufficient to fully
            reimburse such Interest Advance, plus interest thereon at the Reimbursement Rate within a reasonable period of time.  The Backup Advancing Agent will be entitled to conclusively rely on any affirmative determination by the Advancing Agent that
            an Interest Advance would have been a Nonrecoverable Interest Advance.  Absent bad faith, the determination by the Advancing Agent or the Backup Advancing Agent, as applicable, as to the nonrecoverability of any Interest Advance shall be
            conclusive and binding on the Holders of the Notes.

        

        

        (c)          Each of the Advancing Agent and the Backup
            Advancing Agent may recover any previously unreimbursed Interest Advance made by it (including any Nonrecoverable Interest Advance), together with interest thereon, first, from Interest Proceeds and second (to the extent that there are insufficient Interest Proceeds for such reimbursement), from
            Principal Proceeds to the extent that such reimbursement would not trigger an additional Interest Shortfall; provided that if at any time an Interest Advance is
            determined to be a Nonrecoverable Interest Advance, the Advancing Agent or the Backup Advancing Agent shall be entitled to recover all outstanding Interest Advances from the Collection Account pursuant to the Servicing Agreement on any Business
            Day during any Interest Accrual Period prior to the related Determination Date.  The Advancing Agent shall be permitted (but not obligated) to defer or otherwise structure the timing of recoveries of Nonrecoverable Interest Advances in such
            manner as the Advancing Agent determines is in the best interest of the Holders of the Notes, as a collective whole, which may include being reimbursed for Nonrecoverable Interest Advances in installments.

        

        

        
          -150-

          
            


        

        (d)        The Advancing Agent and the Backup Advancing Agent
            will each be entitled with respect to any Interest Advance made by it (including Nonrecoverable Interest Advances) to interest accrued on the amount of such Interest Advance for so long as it is outstanding at the Reimbursement Rate.

        

        

        (e)          The obligations of the Advancing Agent and the
            Backup Advancing Agent to make Interest Advances in respect of the Class A Notes, the Class A-S Notes and the Class B Notes will continue through the Stated Maturity Date, unless the Class A Notes, the Class A-S Notes and the Class B Notes are
            previously redeemed or repaid in full.

        

        

        (f)           In no event will the Advancing Agent, in its
            capacity as such hereunder or the Note Administrator, in its capacity as Backup Advancing Agent hereunder, be required to advance any amounts in respect of payments of principal of any Collateral Interest or Note.

        

        

        (g)          In consideration of the performance of its
            obligations hereunder, the Advancing Agent shall be entitled to receive, at the times set forth herein and subject to the Priority of Payments, to the extent funds are available therefor, the Advancing Agent Fee.  For so long as the Seller (or
            one of its Affiliates) (i) is the Advancing Agent and (ii) owns the Preferred Shares, the Advancing Agent hereby agrees, on behalf of itself and its affiliates, to waive its rights to receive the Advancing Agent Fee and any Reimbursement
            Interest.  The Note Administrator shall not be entitled to an additional fee in respect of its role as Backup Advancing Agent.  If the Advancing Agent is terminated for failing to make an Interest Advance hereunder (as provided in Section 16.5(d)) (or for failing to make a Servicing Advance under the Servicing Agreement) that the Advancing Agent did not determine to be nonrecoverable, the Backup
            Advancing Agent or any applicable subsequent successor advancing agent will be entitled to receive the Advancing Agent Fee (plus Reimbursement Interest on any Interest Advance made by the Backup Advancing Agent or the applicable subsequent
            successor advancing agent) and shall make Interest Advances until a successor Advancing Agent is appointed under the Indenture.

        

        

        (h)        The determination by the Advancing Agent or the
            Backup Advancing Agent (in its capacity as successor Advancing Agent), as applicable, (i) that it has made a Nonrecoverable Interest Advance (together with Reimbursement Interest thereon) or (ii) that any proposed Interest Advance, if made,
            would constitute a Nonrecoverable Interest Advance, shall be evidenced by an Officer’s Certificate delivered promptly to the Trustee, the Note Administrator, the Issuer and the 17g-5 Information Provider, setting forth the basis for such
            determination; provided that failure to give such notice, or any defect therein, shall not impair or affect the validity of, or the Advancing Agent or the Backup
            Advancing Agent, entitlement to reimbursement with respect to, any Interest Advance.

            Manager may from time to time request in writing with respect to the Collateral or the Indenture Accounts and provide any other information reasonably available to the Note Administrator by reason of its acting as Note Administrator hereunder
            and required to be provided by Section 10.9 or to permit the Collateral Manager to perform its obligations under the Collateral Management Agreement.  Each of the
            Issuer, the Servicer, and the Special Servicer shall promptly forward to the Collateral Manager, the Trustee and the Note Administrator any information in their possession or reasonably available to them concerning any of the Collateral that
            the Trustee or the Note Administrator reasonably may request or that reasonably may be necessary to enable the Note Administrator to prepare any report or to enable the Trustee or the Note Administrator to perform any duty or function on its
            part to be performed under the terms of this Indenture.

            number, Aggregate Outstanding Portfolio Balance, weighted average remaining term to maturity and weighted average interest rate of the Collateral Interests as of the end of the related Due Period;

              Note Administrator and the applicable Q&A Respondent, unless such party determines not to answer such Inquiry as provided below, shall reply to the Inquiry, which reply of the applicable Q&A Respondent shall be by email to the Note
              Administrator, the Servicer and the Special Servicer or such other method as the Note Administrator and the Servicer or the Special Servicer will agree.  The Note Administrator shall post (within a commercially reasonable period of time
              following preparation or receipt of such answer, as the case may be) such Inquiry and the related answer to the Note Administrator’s Website.  If the Note Administrator or
              the applicable Q&A Respondent determines, in its respective sole discretion, that (i) any Inquiry is not of a type described above, (ii) answering any Inquiry would not be in the best interests of the Issuer or the Noteholders, (iii)
              answering any Inquiry would be in violation of applicable law, the Loan Documents, the Collateral Management Agreement, this Indenture or the Servicing Agreement, (iv) answering any Inquiry would materially increase the duties of, or result
              in significant additional cost or expense to, the Note Administrator, the Collateral Manager, the Servicer or the Special Servicer, as applicable or (v) answering any such inquiry would reasonably be expected to result in the waiver of an
              attorney client privilege or the disclosure of attorney work product, or is otherwise not advisable to answer, it shall not be required to answer such Inquiry and shall promptly notify the Note Administrator of such determination.  The Note
              Administrator shall notify the Person who submitted such Inquiry in the event that the Inquiry shall not be answered in accordance with the terms of this Indenture.  Any
              notice by the Note Administrator to the Person who submitted an Inquiry that shall not be answered shall include the following statement: “Because the Indenture and the Servicing Agreement provides that the Note Administrator, the Collateral
              Manager, the Servicer, and the Special Servicer shall not answer an Inquiry if it determines, in its respective sole discretion, that (i) any Inquiry is beyond the scope of the topics described in the Indenture, (ii) answering any Inquiry
              would not be in the best interests of the Issuer and/or the Noteholders, (iii) answering any Inquiry would be in violation of applicable law or the Loan Documents, the Collateral Management Agreement, this Indenture or the Servicing
              Agreement, (iv) answering any Inquiry would materially increase the duties of, or result in significant additional cost or expense to, the Note Administrator, the Collateral


              Manager, the Servicer or the Special Servicer, as applicable, or (v) answering any such inquiry would reasonably be expected to result in the waiver of an attorney client privilege or the disclosure of attorney work product, or is otherwise
              not advisable to answer, no inference shall be drawn from the fact that the Trustee, the Collateral Manager, the Servicer or the Special Servicer has declined to answer the Inquiry.” Answers posted on the Investor Q&A Forum shall be

        (b)         The Note Administrator shall make available to
            any Noteholder or holder of Preferred Shares and any beneficial owner of a Note, the Investor Registry.  The “Investor Registry” shall be a voluntary service available on the Note Administrator’s Website, where Noteholders and beneficial owners

            Noteholder, a beneficial owner of a Note or a holder of a Preferred Share and (ii) it grants authorization to the Note Administrator to make its name and contact information available on the Investor Registry for at least 45 days from the date
            of such certification to other registered Noteholders and registered beneficial owners or Notes.  Such Person shall then be asked to enter certain mandatory fields such as the individual’s name, the company name and email address, as well as
            certain optional fields such as address, and phone number.  If any Noteholder or beneficial owner of a Note notifies the Note Administrator that it wishes to be removed from the Investor Registry (which notice may not be within forty-five (45)
            days of its registration), the Note Administrator shall promptly remove it from the Investor Registry.  The Note Administrator shall not be responsible for verifying or validating any information submitted on the Investor Registry, or for
            monitoring or otherwise maintaining the accuracy of any information thereon.  The Note Administrator may require acceptance of a waiver and disclaimer for access to the Investor Registry.

            the case may be, the 17g-5 Information Provider shall forward such inquiry or request to the Note Administrator, the Collateral Manager, the Servicer or the Special Servicer, as applicable, in each case via email within a commercially
            reasonable period of time following receipt thereof.  The Trustee, the Note Administrator, the Collateral Manager, the Servicer or the Special Servicer, as applicable, will be required to answer each inquiry, unless it determines that (a)
            answering the inquiry would be in violation of applicable law, the Servicing Standard, the Collateral Management Standard, the Indenture, the Collateral Management Agreement, the Servicing Agreement, or the applicable loan documents, (b)
            answering the inquiry would or is reasonably expected to result in a waiver of an attorney-client privilege or the disclosure of attorney work product, or (c) answering the inquiry would materially increase the duties of, or result in
            significant additional cost or expense to, such party, and the performance of such additional duty or the payment of such additional cost or expense is beyond the scope of its duties under the Indenture or the Servicing Agreement, as
            applicable.  In the event that any of the Trustee, the Note Administrator, the Servicer or the Special Servicer declines to answer an inquiry, it shall promptly email the 17g-5 Information Provider with the basis of such declination.  The 17g-5
            Information Provider will be required to post the inquiries and the related answers (or reports, as applicable) on the Rating Agency Q&A Forum and Servicer Document Request Tool promptly upon receipt, or in the event that an inquiry is

        SALE AND EXCHANGES OF COLLATERAL INTERESTS; FUTURE FUNDING ESTIMATES

        

        

        Section 12.1       Sales and Exchanges of Collateral Interests.

        

        

        (a)          Except as otherwise expressly permitted or
            required by this Indenture, the Issuer shall not sell or otherwise dispose of any Collateral Interest.  The Collateral Manager, on behalf of the Issuer, acting pursuant to the Collateral Management Agreement may direct the Special Servicer in
            writing to sell at any time:

        

        

        (i)            any
            Defaulted Collateral Interest;

        

        

        (ii)         any
            Credit Risk Collateral Interest unless (x) the Note Protection Tests were not satisfied as of the immediately preceding Determination Date and have not been cured as of the proposed sale date or (y) the Trustee, upon written direction of a
            majority of the Controlling Class, has provided written notice to the Collateral Manager that no further sales of Credit Risk Collateral Interests will be permitted and such notice has not been withdrawn by the Trustee; or

        

        

        (iii)          any
            Collateral Interest acquired in violation of the Eligibility Criteria, the Reinvestment Criteria or the Acquisition and Disposition Requirements.

        

        

        Sales of Credit Risk Collateral Interests during the Reinvestment Period shall only be permitted for so long as the subject sale
            does not cause the Disposition Limitation Threshold to be met.

        

        

        The Special Servicer shall sell any Collateral Interest in any sale permitted pursuant to this Section 12.1(a), as directed by the Collateral Manager.  Promptly after any sale pursuant to this Section 12.1(a),
            the Collateral Manager shall notify the 17g-5 Information Provider of the Collateral Interest sold and the sale price and shall provide such other information relating to such sale as may be reasonably requested by the Rating Agencies.

        

        

        In connection with the sale of a Credit Risk Collateral Interest or a Defaulted Collateral Interest pursuant to this Section 12.1(a), the Collateral Manager may also cause the Issuer to create one or more participation interests in such Credit Risk Collateral Interest or a Defaulted
            Collateral Interest and direct the Special Servicer to sell one or more of such participation interests.

        

        

        
          -168-

          
            


        

        If a Collateral Interest that is a Defaulted Collateral Interest is not sold or otherwise disposed of by the Issuer within three (3)
            years of such Collateral Interest becoming a Defaulted Collateral Interest, the Collateral Manager shall use commercially reasonable efforts to cause the Issuer to sell or otherwise dispose of such Collateral Interest as soon as commercially
            practicable thereafter.  The Issuer or the Collateral Manager shall not sell or otherwise dispose of any Collateral Interest for the primary purpose of recognizing gains or decreasing losses resulting from market value changes.

        

        

        (b)          In addition, with respect to
            any Credit Risk Collateral Interest permitted to be sold pursuant to Section 12.1(a), such Credit Risk Collateral Interest may be sold by the Issuer at the
            direction of the Collateral Manager:

        

        

        (i)           to an entity, other than the
            Collateral Manager or an affiliate thereof; or

        

        

        (ii)          to the Collateral Manager or
            an affiliate thereof that is purchasing such Credit Risk Collateral Interest from the Issuer (any purchase described in this clause (ii) is referred to herein as, a “Credit Risk
                Collateral Interest Cash Purchase”) for a cash purchase price that is:

        

        

        (a)          until the
            Disposition Par Limitation Threshold has been met, equal to or greater than the Par Purchase Price thereof; and

        

        

        (b)          after the
            Disposition Par Limitation Threshold has been met following disclosure to, and approval by, the Advisory Committee equal to the greater of (A) the Par Purchase Price thereof and (B) the fair market value thereof.

        

        

        (c)          A Credit Risk Collateral
            Interest may be disposed of at any time, following disclosure to, and approval by, the Advisory Committee, by the Collateral Manager directing the Issuer to exchange such Credit Risk Collateral Interest for (1) a Collateral Interest owned by
            the Collateral Manager or an Affiliate of the Collateral Manager that satisfies the Eligibility Criteria and the Acquisition and Disposition Requirements (such Collateral Interest, an “Exchange Collateral Interest”) or (2) a combination of an Exchange Collateral Interest and cash (such exchange for a Credit Risk Collateral Interest, a “Credit Risk Collateral Interest Exchange”); provided that the sum of (1) the Principal Balance of such Exchange Collateral
            Interest plus all accrued and unpaid interest thereon plus (2) the cash amount (if any) to be paid to the Issuer by the Collateral Manager or an affiliate of the Collateral Manager, in connection with such exchange, is equal to or greater than:

        

        

        (i)            until
            the Disposition Par Limitation Threshold has been met, the Par Purchase Price of the Credit Risk Collateral Interest sought to be exchanged; and

        

        

        (ii)           after
            the Disposition Par Limitation Threshold has been met following disclosure to, and approval by, the Advisory Committee, the greater of (x) the Par Purchase Price of the Credit Risk Collateral Interest sought to be exchanged and (y) the fair
            market value of such Credit Risk Collateral Interest.

        

        

        
          -169-

          
            


        

        Exchanges of Credit Risk Collateral Interests at all times shall only be permitted for so long as the subject exchange does not
            cause the Disposition Limitation Threshold to be met.

        

        

        (d)          In addition to the above, the Majority of
            Preferred Shareholders shall have the right to purchase (i) any Defaulted Collateral Interest for a purchase price equal to the Par Purchase Price and (ii) any Credit Risk Collateral Interest for a purchase price equal to, (x) until the
            Disposition Par Limitation Threshold has been met, the Par Purchase Price, and (y) after the Disposition Par Limitation Threshold has been met following disclosure to, and approval by, the Advisory Committee the greater of (1) the Par Purchase
            Price and (2) the fair market value thereof.

        

        

        During the Reinvestment Period, the Majority of Preferred Shareholders’ right to purchase Credit Risk Collateral Interests shall be
            permitted only for so long as the subject sale does not cause the Disposition Limitation Threshold to be met.

        

        

        (e)          If the Collateral Manager directs the sale of a
            Defaulted Collateral Interest pursuant to Section 12.1(a), the Special Servicer shall sell such Defaulted Collateral Interest for a price that the Special Servicer
            determines, in accordance with the Servicing Standard, to be at least equal to the fair market value of such Defaulted Collateral Interest, provided that if the
            purchaser of such Defaulted Collateral Interest is the Collateral Manager, the Special Servicer or an Affiliate thereof, the Trustee shall determine that such offer is for at least the fair market value of such Defaulted Collateral Interest. 
            In addition, with respect to any exchange of a Collateral Interest and any exercise of the Majority of Preferred Shareholders’ right to purchase Credit Risk Collateral Interests, the determination of fair market value, to the extent it is
            applicable, shall be made by the Trustee.  In connection with any determination of fair market value required to be made by the Trustee, the Trustee shall retain an independent third party expert in real estate or commercial mortgage loan
            matters with at least five (5) years’ experience in valuing or investing in real estate loans similar to such Defaulted Collateral Interest, that has been selected with reasonable care by the Trustee to determine the fair market value for such
            Defaulted Collateral Interest. The Trustee shall conclusively rely upon any such third party determination, and all reasonable fees and costs of any appraisals, inspection reports, and opinions of value incurred by any such third party shalll
            be covered by, and shall be paid in advance of any determination by the Collateral Manager or its Affiliate; provided that the Trustee may not engage a third-party
            expert whose fees exceed a commercially reasonable amount as determined by the Trustee.

        

        

        (f)          If the Collateral Manager directs the sale a
            Collateral Interest acquired in violation of the Eligibility Criteria, the Reinvestment Criteria or the Acquisition and Disposition Requirements, the Issuer may sell such Collateral Interest to the Collateral Manager or an Affiliate thereof for
            a cash purchase price that is equal to its Par Purchase Price.

        

        

        (g)          After the Issuer has notified the Trustee and the
            Note Administrator of an Optional Redemption, a Clean-up Call, a Tax Redemption or an Auction Call Redemption in accordance with Section 9.1, the Collateral Manager,
            on behalf of the Issuer, and acting pursuant to the Collateral Management Agreement, may at any time direct the Trustee (in the case of an Optional Redemption, Clean-up Call Redemption or Tax Redemption) or the Special Servicer (in the case of
            an Auction Call Redemption) in writing by Issuer Order to sell, and the Trustee or the Special Servicer, as applicable, shall sell in the manner directed by the Majority of Preferred Shareholders in writing, any Collateral Interest without
            regard to the foregoing limitations in Section 12.1(a); provided that:

        

        

        
          -170-

          
            


        

        (i)           the Sale
            Proceeds therefrom must be used to pay certain expenses and redeem all of the Notes in whole but not in part pursuant to Section 9.1, and upon any such sale
            the Trustee shall release the lien of such Collateral Interest, and the Custodian shall, upon receipt of a Request for Release, release the related Collateral Interest File, pursuant to Section 10.10;

        

        

        (ii)          the
            Collateral Manager on behalf of the Issuer shall not sell (and the Trustee shall not be required to release) a Collateral Interest pursuant to this Section 12.1(f)
            unless the Collateral Manager certifies to the Trustee and the Note Administrator that, in the Collateral Manager’s reasonable business judgment based on calculations included in the certification (which shall include the sales prices of the
            Collateral Interests), the Sale Proceeds from the sale of one or more of the Collateral Interests and all Cash and proceeds from Eligible Investments will be at least equal to the Total Redemption Price; and

        

        

        (iii)          in connection with an Optional Redemption, a Clean-Up Call, a Tax Redemption or an Auction Call Redemption, all the Collateral Interests to be sold pursuant to this Section 12.1(f) must be sold in accordance with the requirements set forth in Section 9.1(f).

        

        

        (h)          In the event that any Notes remain Outstanding as
            of the Payment Date occurring six months prior to the Stated Maturity Date of the Notes, the Collateral Manager will be required to determine whether the proceeds expected to be received on the Collateral Interests prior to the Stated Maturity
            Date of the Notes will be sufficient to pay in full the principal amount of (and accrued interest on) the Notes on the Stated Maturity Date.  If the Collateral Manager determines, in its sole discretion, that such proceeds will not be
            sufficient to pay the outstanding principal amount of and accrued interest on the Notes (a “Note Liquidation Event”) on the Stated Maturity Date of the Notes, the
            Issuer will, at the direction of the Collateral Manager, be obligated to liquidate the portion of Collateral Interests sufficient to pay the remaining principal amount of and interest on the Notes on or before the Stated Maturity Date.  The
            Collateral Interests to be liquidated by the Issuer will be selected by the Collateral Manager.

        

        

        (i)          Notwithstanding anything herein to the contrary,
            the Collateral Manager on behalf of the Issuer shall be permitted to sell to a Permitted Subsidiary any Sensitive Asset for consideration consisting of equity interests in such Permitted Subsidiary (or an increase in value of equity interests
            already owned).

        

        

        (j)          In the case of a sale of a Credit Risk Collateral
            Interest or a Defaulted Collateral Interest, or the exchange of a Credit Risk Collateral Interest, in each case, which is a Combined Loan, the related Mortgage Loan and the corresponding Mezzanine Loan shall be sold or exchanged together.

        

        

        
          -171-

          
            


        

        (k)           Under no circumstances shall the Trustee be
            required to acquire any Collateral Interests or property related thereto.

        

        

        (l)           Any Collateral Interest sold pursuant to this Section 12.1 shall be released from the lien of this Indenture.

        (a)          Except as provided in Section 12.3(c), during the Reinvestment Period, amounts (or Eligible Investments) credited to the Reinvestment
            Account may, but are not required to, be reinvested in Reinvestment Collateral Interests (which shall be, and hereby are upon acquisition by the Issuer, Granted to the Trustee pursuant to the Granting Clause of this Indenture) that satisfy the
            applicable Eligibility Criteria and the Acquisition and Disposition Requirements and the following additional criteria (the “Reinvestment Criteria”), as evidenced by
            an Officer’s Certificate of the Collateral Manager on behalf of the Issuer delivered to the Trustee, delivered as of the date of the commitment to purchase such Reinvestment Collateral Interests:

        

        

        (i)           the Note
            Protection Tests are satisfied; and

        

        

        (ii)          no Event
            of Default has occurred and is continuing.

        

        

        (b)          Notwithstanding the foregoing provisions, (i)
            Cash on deposit in the Reinvestment Account may be invested in Eligible Investments pending investment in Reinvestment Collateral Interests and (ii) if an Event of Default shall have occurred and be continuing, no Reinvestment Collateral
            Interest may be acquired unless it was the subject of a commitment entered into by the Issuer prior to the occurrence of such Event of Default.

        

        

        (c)          Notwithstanding the foregoing provisions, at any
            time when the Retention Holder or any Affiliate that is wholly-owned by KREF Sub-REIT and a “disregarded entity” for U.S. federal income tax purposes continues to own 100% of the
              Preferred Shares, it may contribute additional Cash, Eligible Investments and Collateral Interests to the Issuer so long as, in the case of Collateral Interests, any such Collateral Interests satisfy the Eligibility Criteria at the
            time of such contribution, including, but not limited to, for purposes of effecting any cure rights reserved for the holder of the Pari Passu Participations, pursuant to and in accordance with the terms of the related Participation Agreement. 
            Cash or Eligible Investments contributed to the Issuer by the Retention Holder (during the Reinvestment Period) shall be credited to the Reinvestment Account (unless the Retention Holder directs otherwise) and may be reinvested by the Issuer in
            Reinvestment Collateral Interests so long as no Event of Default has occurred and is continuing.

        (a)         Any transaction effected after the Closing Date
            under this Article 12 shall be conducted in accordance with the requirements of the Collateral Management Agreement; provided that (1) the Collateral Manager shall not direct the Special Servicer to acquire any Collateral Interest for
            inclusion in the Collateral from the Collateral Manager or any of its Affiliates as principal or to sell any Collateral Interest from the Collateral to the Collateral Manager or any of its Affiliates as principal unless the transaction is
            effected in accordance with the Collateral Management Agreement and (2) the Collateral Manager shall not direct the Special Servicer to acquire any Collateral Interest for inclusion in the Collateral from any account or portfolio for which the
            Collateral Manager serves as investment adviser or direct the Special Servicer to sell any Collateral Interest to any account or portfolio for which the Collateral Manager serves as investment adviser unless such transactions comply with the
            Collateral Management Agreement and Section 206(3) of the Advisers Act.  The Special Servicer shall have no responsibility to oversee compliance with this clause by the other parties.

            Collateral Interest or Securities shall be registered in the name of the Issuer, and the Trustee (or the Custodian on its behalf) shall receive such Pledged Collateral Interest or Securities as evidenced by the Collateral Interest File.  The original note and/or participation certificate and all allonges thereto or assignments thereof that are required to be included in the Collateral Interest File related to any
            Reinvestment Collateral Interest or Exchange Collateral Interest acquired by the Issuer after the Closing Date shall be delivered no later than one (1) Business Day before the date of acquisition of such Reinvestment Collateral Interest or
            Exchange Collateral Interest, as applicable, by the Issuer and the remaining documents constituting such Collateral Interest File shall be delivered by no later than three (3) Business Days after the date of acquisition.

        

        

        (c)          Notwithstanding anything contained in this Article 12 to the contrary, the Issuer shall, subject to this Section 12.3(c), have the right

        Section 12.4          Modifications to Note Protection Tests.

        

        

        In the event that (1) Moody’s modifies the definitions or calculations relating to any of the Moody’s specific Eligibility Criteria
            or (2) any Rating Agency modifies the definitions or calculations relating to either of the Note Protection Tests (each, a “Rating Agency Test Modification”), in any
            case in order to correspond with published changes in the guidelines, methodology or standards established by such Rating Agency, the Issuer may, but is under no obligation solely as a result of this Section 12.4 to, incorporate corresponding changes into this Indenture by an amendment or supplement hereto without the consent of the Holders of the Notes (except as provided below) (but with written notice
            to the Noteholders) or the Preferred Shares if (x) in the case of a modification of a Moody’s specific Eligibility Criteria, the Rating Agency Condition is satisfied with respect to Moody’s, (y) in the case of a modification of a Note
            Protection Test, the Rating Agency Condition is satisfied with respect to each Rating Agency then rating any Class of Notes and (z) written notice of such modification is delivered by the Collateral Manager to the Note Administrator and the
            Trustee and the Holders of the Notes and Preferred Shares (which notice may be included in the next regularly scheduled report to Noteholders).  Any such Rating Agency Test Modification shall be effected without execution of a supplemental
            indenture; provided, however, that such amendment shall be (i) evidenced by a written
            instrument executed and delivered by each of the Co‐Issuers and the Collateral Manager and delivered to the Trustee, and (ii) accompanied by delivery by the Issuer to the Trustee of an Officer’s Certificate of the Issuer (or the Collateral

        Section 12.5          Ongoing Future Advance Estimates.

        

        

        (a)         The Note Administrator and the Trustee, on behalf
            of the Noteholders and the Holders of the Preferred Shares, are hereby directed by the Issuer to (i) enter into the Future Funding Agreement and the Future Funding Account Control Agreement, pursuant to which the Seller will agree to pledge
            certain collateral described therein in order to secure certain future funding obligations of any Affiliated Future Funding Companion Participation Holder as holder of any Future Funding Companion Participations and (ii) administer the rights
            of the Note Administrator and the secured party, as applicable, under the Future Funding Agreement and the Future Funding Account Control Agreement.  In the event an Access Termination Notice (as defined in the Future Funding Agreement) has
            been sent by the Note Administrator to the related account bank and for so long as such Access Termination Notice is not withdrawn by the Note Administrator, the Note Administrator shall, pursuant to the direction of the Issuer or the Special
            Servicer on its behalf, direct the use of funds on deposit in the Future Funding Controlled Reserve Account pursuant to the terms of the Future Funding Agreement.  Neither the Trustee nor the Note Administrator shall have any obligation to
            ensure that the Seller is depositing or causing to be deposited all amounts into the Future Funding Controlled Reserve Account that are required to be deposited therein pursuant to the Future Funding Agreement.

        

        

        (b)         Pursuant to the Future Funding Agreement, on the Closing Date, (i) KREF Holdings, in its capacity as Future Funding Indemnitor, shall deliver its Largest One Quarter Future Advance Estimate to the Collateral Manager, the

              certification of a responsible financial officer of the Future Funding Indemnitor that the Future Funding Indemnitor has Segregated Liquidity at least equal to the Largest One Quarter Future Advance Estimate.  Thereafter, so long as any
              Future Funding Companion Participation is held by an Affiliated Future Funding Companion Participation Holder and any future advance obligations remain outstanding under
              such Future Funding Companion Participation, no later than the 18th day (or, if such day is not a Business Day, the next succeeding Business Day) of the calendar-month preceding the beginning of each calendar quarter, the Future Funding
              Indemnitor shall deliver (which may be by email) to the Collateral Manager, the Servicer, the Special Servicer, the Note Administrator and the 17g-5 Information Provider a certification of a responsible financial officer of the Future Funding
              Indemnitor that the Future Funding Indemnitor has Segregated Liquidity equal to the greater of (i) the Largest One Quarter Future Advance Estimate or (ii) the controlling Two Quarter Future Advance Estimate for the immediately following two

              Seller is required to deliver to the Collateral Manager, the Servicer, the Special Servicer, the Note Administrator and the Future Funding Indemnitor (i) a Two Quarter Future Advance Estimate for the immediately following two calendar
              quarters and (ii) such supporting documentation and other information (including any relevant calculations) as is reasonably necessary for the Servicer to perform its obligations described below.  The Issuer shall cause the Servicer to,
              within ten (10) days after receipt of the Two Quarter Future Advance Estimate and supporting documentation from the Seller, (A) review the Seller’s Two Quarter Future Advance Estimate and such supporting documentation and other information
              provided by the Seller in connection therewith, (B) consult with the Seller with respect thereto and make such inquiry, and request such additional information (and the Seller shall promptly respond to each such request for consultation,
              inquiry or request for information), in each case as is commercially reasonable for the Servicer to perform its obligations described in the following clause (C), and (C) by written notice to the Note Administrator, the Seller and the Future
              Funding Indemnitor substantially in the form set forth in the Servicing Agreement, either (1) confirm that nothing has come to the attention of the Servicer in the documentation provided by the Seller that in the reasonable opinion of the
              Servicer would support a determination of a Two Quarter Future Advance Estimate that is at least 25% higher than the Seller’s Two Quarter Future Advance Estimate for such period and shall state that the Seller’s Two Quarter Future Advance
              Estimate for such period shall control or (2) deliver its own Two Quarter Future Advance Estimate for such period.  If the Servicer’s Two Quarter Future Advance Estimate
              is at least 25% higher than the Seller’s Two Quarter Future Advance Estimate for any period, then the Servicer’s Two Quarter Future Advance Estimate for such period shall control; otherwise, the Seller’s Two Quarter Future Advance Estimate
              for such period shall control.

        

        

        (d)         No Two Quarter Future Advance Estimate shall be
            made by the Seller or the Servicer for a calendar quarter if, by the fifth (5th) day of the calendar-month preceding the beginning of such calendar quarter, the Future
            Funding Indemnitor delivers (which may be by email) to the Collateral Manager, the Servicer, the Special Servicer, the Note Administrator and the 17g-5 Information Provider a certificate of a responsible financial officer of the Future Funding
            Indemnitor certifying that (i) the Future Funding Indemnitor has Segregated Liquidity equal to at least 100% of the aggregate amount of outstanding future advance obligations (subject to the same exclusions as the calculation of the Two Quarter
            Future Advance Estimate) under the Future Funding Companion Participations held by Affiliated Future Funding Companion Participation Holders or (ii) no such future funding
            obligations remain outstanding under the Future Funding Companion Participations held by Affiliated Future Funding Companion Participation Holders.  All certifications regarding Segregated Liquidity, any Two Quarter Future Advance Estimates, or
            any notices described in (b) and (c) above shall be emailed to the Note Administrator at trustadministrationgroup@wellsfargo.com and cts.cmbs.bond.admin@wellsfargo.com or
            such other email address as provided by the Note Administrator.

        Section 14.1          Form of Documents Delivered to the Trustee and Note Administrator.

        

        

        In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not
            necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters
            and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

        

        

        
          -178-

          
            


        

        Any certificate or opinion of an Authorized Officer of the Issuer or the Co-Issuer may be based, insofar as it relates to legal
            matters, upon a certificate or opinion of, or representations by, counsel, unless such Authorized Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters
            upon which his certificate or opinion is based are erroneous.  Any such certificate of an Authorized Officer of the Issuer or the Co-Issuer or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or
            opinion of, or representations by, the Issuer, the Co-Issuer, the Collateral Manager or any other Person, stating that the information with respect to such factual matters is in the possession of the Issuer, the Co-Issuer, the Collateral
            Manager or such other Person, unless such Authorized Officer of the Issuer or the Co-Issuer or such counsel knows that the certificate or opinion or representations with respect to such matters are erroneous.  Any Opinion of Counsel also may be
            based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an Authorized Officer of the Issuer or the Co-Issuer, or the Collateral Manager on behalf of the Issuer, certifying as to the factual
            matters that form a basis for such Opinion of Counsel and stating that the information with respect to such matters is in the possession of the Issuer or the Co-Issuer or the Collateral Manager on behalf of the Issuer, unless such counsel knows
            that the certificate or opinion or representations with respect to such matters are erroneous.

        

        

        Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements,
            opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

        

        

        Whenever in this Indenture it is provided that
            the absence of the occurrence and continuation of a Default or Event of Default is a condition precedent to the taking of any action by the Trustee or the Note Administrator at the request or direction of the Issuer or the Co-Issuer, then
            notwithstanding that the satisfaction of such condition is a condition precedent to the Issuer’s or the Co-Issuer’s rights to make such request or direction, the Trustee or the Note Administrator shall be protected in acting in accordance with
            such request or direction if it does not have knowledge of the occurrence and continuation of such Default or Event of Default as provided in Section 6.1(g).

        

        

        Section 14.2          Acts of Securityholders.

        

        

        (a)          Any request, demand, authorization, direction,
            notice, consent, waiver or other action provided by this Indenture to be given or taken by Securityholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Securityholders in person or by
            an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and the Note Administrator, and, where it is hereby
            expressly required, to the Issuer and/or the Co-Issuer.  Such instrument or instruments (and the action or actions embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Securityholders signing such instrument or instruments.  Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture
            and conclusive in favor of the Trustee, the Note Administrator, the Issuer and the Co-Issuer, if made in the manner provided in this Section 14.2.

        (b)          The fact and date of the execution by any Person
            of any such instrument or writing may be proved in any manner which the Trustee or the Note Administrator deems sufficient.

        

        

        (c)          The principal amount and registered numbers of
            Notes held by any Person, and the date of his holding the same, shall be proved by the Notes Register.  The Notional Amount and registered numbers of the Preferred Shares held by any Person, and the date of his holding the same, shall be proved
            by the register of members maintained with respect to the Preferred Shares.  Notwithstanding the foregoing, the Trustee and Note Administrator may conclusively rely on an Investor Certification to determine ownership of any Notes.

        

        

        (d)        Any request, demand, authorization, direction,
            notice, consent, waiver or other action by the Securityholder shall bind such Securityholder (and any transferee thereof) of such Security and of every Security issued upon the registration thereof or in exchange therefor or in lieu thereof, in

        Section 14.4          Notices to Noteholders; Waiver.

        

        

        Except as otherwise expressly provided herein, where this Indenture or the Servicing Agreement provides for notice to Holders of
            Notes of any event,

        

        

        (a)          such notice shall be sufficiently given to
            Holders of Notes if in writing and mailed, first class postage prepaid, to each Holder of a Note affected by such event, at the address of such Holder as it appears in the Notes Register, not earlier than the earliest date and not later than
            the latest date, prescribed for the giving of such notice;

        

        

        (b)          such notice shall be in the English language; and

        

        

        (c)          all reports or notices to Preferred Shareholders
            shall be sufficiently given if provided in writing and mailed, first class postage prepaid, to the Preferred Share Paying Agent.

          -183-

          
            


        

        Neither the failure to mail any notice, nor any defect in any notice so mailed, to any particular Holder of a Note shall affect the
            sufficiency of such notice with respect to other Holders of Notes.  In case by reason of the suspension of regular mail service or by reason of any other cause, it shall be impracticable to give such notice by mail, then such notification to
            Holders of Notes shall be made with the approval of the Note Administrator and shall constitute sufficient notification to such Holders of Notes for every purpose hereunder.

        

        

        Where this Indenture provides for notice in any manner, such notice may be waived in writing by any Person entitled to receive such
            notice, either before or after the event, and such waiver shall be the equivalent of such notice.  Waivers of notice by Noteholders shall be filed with the Trustee and with the Note Administrator, but such filing shall not be a condition
            precedent to the validity of any action taken in reliance upon such waiver.

        

        

        In the event that, by reason of the suspension of the regular mail service as a result of a strike, work stoppage or similar
            activity, it shall be impractical to mail notice of any event to Noteholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee and
            the Note Administrator shall be deemed to be a sufficient giving of such notice.

        

        

        Section 14.5          Effect of Headings and Table of Contents.

            whether so expressed or not.

        

        

        Section 14.7          Severability.

            enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

        

        

        Section 14.8          Benefits of Indenture.

            express third party beneficiary hereunder), any benefit or any legal or equitable right, remedy or claim under this Indenture.

            court sitting in the Borough of Manhattan in The City of New York in any action or proceeding arising out of or relating to the Notes or this Indenture, and each of the Issuer and the Co-Issuer hereby irrevocably agrees that all claims in
            respect of such action or proceeding may be heard and determined in such New York State or federal court.  Each of the Issuer and the Co-Issuer hereby irrevocably waives, to the fullest extent that they may legally do so, the defense of an
            inconvenient forum to the maintenance of such action or proceeding.  Each of the Issuer and the Co-Issuer irrevocably consents to the service of any and all process in any action or proceeding by the mailing or delivery of copies of such
            process to it at the office of the Issuer’s and the Co-Issuer’s agent set forth in Section 7.2.  Each of the Issuer and the Co-Issuer agrees that a final judgment in
            any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

            under this Indenture, the Notes, any such agreement or otherwise and, without prejudice to the generality of the foregoing, neither the Issuer nor the Co-Issuer shall be entitled to take any steps to enforce, or bring any action or proceeding,
            in respect of this Indenture, the Notes, any such agreement or otherwise against the other Co-Issuer or the Issuer, respectively.  In particular, neither the Issuer nor the Co-Issuer shall be entitled to petition or take any other steps for the

        ASSIGNMENT OF THE COLLATERAL INTEREST PURCHASE AGREEMENT

        

        

        Section 15.1          Assignment of Collateral Interest Purchase Agreement.

        

        

        (a)         The Issuer, in furtherance of the covenants of this Indenture and as security for the Notes and amounts payable to the Secured Parties hereunder and the performance and observance of the provisions hereof, hereby collaterally
              assigns, transfers, conveys and sets over to the Trustee, for the benefit of the Noteholders (and to be exercised on behalf of the Issuer by persons responsible therefor pursuant to this Indenture and the Servicing Agreement), all of the Issuer’s estate, right, title and interest in, to and under the Collateral Interest Purchase Agreement (now or hereafter entered into) (an “Article 15 Agreement”), including, without limitation, (i) the right to give all notices, consents and
              releases thereunder, (ii) the right to give all notices of termination and to take any legal action upon the breach of an obligation of the Seller or Collateral Manager thereunder, including the commencement, conduct and consummation of
              proceedings at law or in equity, (iii) the right to receive all notices, accountings, consents, releases and statements thereunder and (iv) the right to do any and all other things whatsoever that the Issuer is or may be entitled to do
              thereunder; provided, however, that the Issuer reserves for itself a license to exercise all of the Issuer’s rights pursuant to the Article 15 Agreement without notice
              to or the consent of the Trustee or any other party hereto (except as otherwise expressly required by this Indenture, including, without limitation, as set forth in Section





                15.1(f)) which license shall be and is hereby deemed to be automatically revoked upon the occurrence of an Event of Default hereunder until such time, if any, that
              such Event of Default is cured or waived.

        

        

        (b)         The assignment made hereby is executed as
            collateral security, and the execution and delivery hereby shall not in any way impair or diminish the obligations of the Issuer under the provisions of each of the Article 15 Agreement, nor shall any of the obligations contained in each of the
            Article 15 Agreement be imposed on the Trustee.

        

        

        (c)          Upon the retirement of the Notes and the release
            of the Collateral from the lien of this Indenture, this assignment and all rights herein assigned to the Trustee for the benefit of the Noteholders shall cease and terminate and all the estate, right, title and interest of the Trustee in, to
            and under each of the Article 15 Agreement shall revert to the Issuer and no further instrument or act shall be necessary to evidence such termination and reversion.

        

        

        (d)          The Issuer represents that it has not executed
            any assignment of the Article 15 Agreement other than this collateral assignment.

        

        

        (e)          The Issuer agrees that this assignment is
            irrevocable, and that it shall not take any action which is inconsistent with this assignment or make any other assignment inconsistent herewith.  The Issuer shall, from time to time upon the request of the Trustee, execute all instruments of
            further assurance and all such supplemental instruments with respect to this assignment as the Trustee may specify.

        

        

        (f)          The Issuer hereby agrees, and hereby undertakes
            to obtain the agreement and consent of the Seller in the Collateral Interest Purchase Agreement to the following:

        

        

        (i)           the
            Seller consents to the provisions of this collateral assignment and agrees to perform any provisions of this Indenture made expressly applicable to the Seller pursuant to the applicable Article 15 Agreement;

        

        

        (ii)         the
            Seller acknowledges that the Issuer is collaterally assigning all of its right, title and interest in, to and under the Collateral Interest Purchase Agreement to the Trustee for the benefit of the Noteholders, and the Seller agrees that all of
            the representations, covenants and agreements made by the Seller in the Article 15 Agreement are also for the benefit of, and enforceable by, the Trustee and the Noteholders;

        

        

        
          -189-

          
            


        

        (iii)         the
            Seller shall deliver to the Trustee duplicate original copies of all notices, statements, communications and instruments delivered or required to be delivered to the Issuer pursuant to the applicable Article 15 Agreement;

        

        

        (iv)        none of
            the Issuer or the Seller shall enter into any agreement amending, modifying or terminating the applicable Article 15 Agreement, (other than in respect of an amendment or modification to cure any inconsistency, ambiguity or manifest error) or
            selecting or consenting to a successor without notifying the Rating Agencies and without the prior written consent and written confirmation of the Rating Agencies that such amendment, modification or termination will not cause its then-current
            ratings of the Notes to be downgraded or withdrawn;

        

        

        (v)         except as
            otherwise set forth herein and therein (including, without limitation, pursuant to Section 12 of the Collateral Management Agreement), the Collateral Manager shall continue to serve as Collateral Manager under the Collateral Management
            Agreement, notwithstanding that the Collateral Manager shall not have received amounts due it under the Collateral Management Agreement because sufficient funds were not then available hereunder to pay such amounts pursuant to the Priority of
            Payments.  The Collateral Manager agrees not to cause the filing of a petition in bankruptcy against the Issuer for the nonpayment of the fees or other amounts payable to the Collateral Manager under the Collateral Management Agreement until
            the payment in full of all Notes issued under this Indenture and the expiration of a period equal to the applicable preference period under the Bankruptcy Code plus ten days following such payment; and

        

        

        (vi)         the
            Collateral Manager irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan in The City of New York in any action or proceeding arising out of or relating to the Notes or
            this Indenture, and the Collateral Manager irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such New York State or federal court.  The Collateral Manager irrevocably waives, to the
            fullest extent it may legally do so, the defense of an inconvenient forum to the maintenance of such action or proceeding.  The Collateral Manager irrevocably consents to the service of any and all process in any action or Proceeding by the
            mailing by certified mail, return receipt requested, or delivery requiring signature and proof of delivery of copies of such initial process to it at c/o Maples Fiduciary Services (Delaware) Inc., 4001 Kennett Pike, Suite 302, Wilmington,
            Delaware 19807.  The Collateral Manager agrees that a final and non-appealable judgment by a court of competent jurisdiction in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment
            or in any other manner provided by law.

        Section 16.1          Liability of the Advancing Agent.

        

        

        The Advancing Agent shall be liable in accordance herewith only to the extent of the obligations specifically imposed upon and
            undertaken by the Advancing Agent.

        

        

        Section 16.2          Merger or Consolidation of the Advancing Agent.

        

        

        (a)          The Advancing Agent will keep in full effect its
            existence, rights and franchises as a corporation under the laws of the jurisdiction in which it was formed, and will obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification
            is or shall be necessary to protect the validity and enforceability of this Indenture to perform its duties under this Indenture.

        

        

        (b)          Any Person into which the Advancing Agent may be
            merged or consolidated, or any corporation resulting from any merger or consolidation to which the Advancing Agent shall be a party, or any Person succeeding to the business of the Advancing Agent shall be the successor of the Advancing Agent,
            hereunder, 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 (it being understood and agreed by the parties hereto that the consummation of
            any such transaction by the Advancing Agent shall have no effect on the Backup Advancing Agent’s obligations under Section 10.7, which obligations shall continue
            pursuant to the terms of Section 10.7).

        

        

        Section 16.3          Limitation on Liability of the Advancing Agent and Others.

            action taken or for refraining from the taking of any action in good faith pursuant to this Indenture, or for errors in judgment; provided, however, that this provision shall not protect the Advancing Agent against liability to the
            Issuer or Noteholders for any breach of warranties or representations made herein or any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or negligence in the performance of duties or by reason of negligent
            disregard of obligations and duties hereunder.  The Advancing Agent and any director, officer, employee or agent of the Advancing Agent may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person
            respecting any matters arising hereunder.  The Advancing Agent and any director, officer, employee or agent of the Advancing Agent shall be indemnified by the Issuer pursuant to the priorities set forth in Section 11.1(a) and held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Indenture or the Notes, other than any loss, liability or
            expense (i) specifically required to be borne by the Advancing Agent pursuant to the terms hereof or otherwise incidental to the performance of obligations and duties hereunder (except as any such loss, liability or expense shall be otherwise
            reimbursable pursuant to this Indenture); or (ii) incurred by reason of any breach of a representation, warranty or covenant made herein, any misfeasance, bad faith or negligence by the Advancing Agent in the performance of or negligent
            disregard of, obligations or duties hereunder or any violation of any state or federal securities law.

        Section 16.4          Representations and Warranties of the Advancing Agent.

        

        

        The Advancing Agent represents and warrants that:

        

        

        (a)          the Advancing Agent (i) has been duly organized,
            is validly existing and is in good standing under the laws of the State of Delaware, (ii) has full power and authority to own the Advancing Agent’s Collateral and to transact the business in which it is currently engaged, and (iii) is duly
            qualified and in good standing under the laws of each jurisdiction where the Advancing Agent’s ownership or lease of property or the conduct of the Advancing Agent’s business requires, or the performance of this Indenture would require, such
            qualification, except for failures to be so qualified that would not in the aggregate have a material adverse effect on the business, operations, Collateral or financial condition of the Advancing Agent or the ability of the Advancing Agent to
            perform its obligations under, or on the validity or enforceability of, the provisions of this Indenture applicable to the Advancing Agent;

        

        

        (b)          the Advancing Agent has full power and authority
            to execute, deliver and perform this Indenture; this Indenture has been duly authorized, executed and delivered by the Advancing Agent and constitutes a legal, valid and binding agreement of the Advancing Agent, enforceable against it in
            accordance with the terms hereof, except that the enforceability hereof may be subject to (i) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors’ rights and (ii) general
            principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law);

        

        

        (c)          neither the execution and delivery of this
            Indenture nor the performance by the Advancing Agent of its duties hereunder conflicts with or will violate or result in a breach or violation of any of the terms or provisions of, or constitutes a default under: (i) the Articles of
            Incorporation and bylaws of the Advancing Agent, (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement or other evidence of indebtedness or other agreement, obligation, condition, covenant or instrument to
            which the Advancing Agent is a party or is bound, (iii) any law, decree, order, rule or regulation applicable to the Advancing Agent of any court or regulatory, administrative or governmental agency, body or authority or arbitrator having
            jurisdiction over the Advancing Agent or its properties, and which would have, in the case of any of (i), (ii) or (iii) of this Section 16.4(c), either individually
            or in the aggregate, a material adverse effect on the business, operations, Collateral or financial condition of the Advancing Agent or the ability of the Advancing Agent to perform its obligations under this Indenture;

        

        

        (d)          no litigation is pending or, to the best of the
            Advancing Agent’s knowledge, threatened, against the Advancing Agent that would materially and adversely affect the execution, delivery or enforceability of this Indenture or the ability of the Advancing Agent to perform any of its obligations
            under this Indenture in accordance with the terms hereof; and

        

        

        (e)          no consent, approval, authorization or order of
            or declaration or filing with any government, governmental instrumentality or court or other Person is required for the performance by the Advancing Agent of its duties hereunder, except such as have been duly made or obtained.

        Section 16.5          Resignation and Removal; Appointment of Successor.

        

        

        (a)          No resignation or removal of the Advancing Agent
            and no appointment of a successor Advancing Agent pursuant to this Article 16 shall become effective until the acceptance of appointment by the successor Advancing
            Agent under Section 16.6.

        

        

        (b)          The Advancing Agent may, subject to Section 16.5(a), resign at any time by giving written notice thereof to the Issuer, the Co-Issuer, the Collateral Manager, the Note Administrator, the Trustee, the
            Servicer, the Noteholders and the Rating Agencies.

        

        

        (c)          The Advancing Agent may be removed at any time by
            Act of Supermajority of the Preferred Shares upon written notice delivered to the Trustee and to the Issuer and the Co-Issuer.

        

        

        (d)          If the Advancing Agent fails to make a required
            Interest Advance and it has not determined such Interest Advance to be a Nonrecoverable Interest Advance the Collateral Manager may, and at the direction of the Majority of the Controlling Class shall, terminate the Advancing Agent and replace
            the Advancing Agent with a successor Advancing Agent, subject to the satisfaction of the Rating Agency Condition.  In the event that the Collateral Manager has not terminated and replaced the Advancing Agent within 30 days of the Advancing
            Agent’s failure to make a required Interest Advance, the Note Administrator may, and at the direction of the Majority of the Controlling Class shall, terminate the Advancing Agent and use commercially reasonable efforts for up to 90 days after
            such termination to appoint a successor Advancing Agent, subject to the satisfaction of the Rating Agency Condition.

        

        

        (e)          Subject to Section 16.5(d), if the Advancing Agent shall resign or be removed, upon receiving such notice of resignation or removal, the Issuer and the Co-Issuer shall promptly appoint a successor advancing
            agent by written instrument, in duplicate, executed by an Authorized Officer of the Issuer and an Authorized Officer of the Co-Issuer, one copy of which shall be delivered to the Advancing Agent so resigning and one copy to the successor
            Advancing Agent, together with a copy to each Noteholder, the Collateral Manager, the Trustee, the Note Administrator, the Servicer and the Special Servicer; provided
            that such successor Advancing Agent shall be appointed only subject to satisfaction of the Rating Agency Condition, upon the written consent of a Majority of Preferred Shareholders.  If no successor Advancing Agent shall have been appointed and
            an instrument of acceptance by a successor Advancing Agent shall not have been delivered to the Advancing Agent within 30 days after the giving of such notice of resignation, the resigning Advancing Agent, the Trustee, the Note Administrator,
            or any Preferred Shareholder, on behalf of himself and all others similarly situated, may petition any court of competent jurisdiction for the appointment of a successor Advancing Agent.

        

        

        (f)          The Issuer and the Co-Issuer shall give prompt
            notice of each resignation and each removal of the Advancing Agent and each appointment of a successor Advancing Agent by mailing written notice of such event by first class mail, postage prepaid, to the Rating Agencies, the Trustee, the Note
            Administrator, and to the Holders of the Notes as their names and addresses appear in the Notes Register.

        Section 16.6          Acceptance of Appointment by Successor Advancing Agent.

        

        

        (a)          Every successor Advancing Agent appointed
            hereunder shall execute, acknowledge and deliver to the Issuer, the Co-Issuer, the Collateral Manager, the Servicer, the Special Servicer, the Trustee, the Note Administrator, and the retiring Advancing Agent an instrument accepting such
            appointment hereunder and under the Servicing Agreement.  Upon delivery of the required instruments, the resignation or removal of the retiring Advancing Agent shall become effective and such successor Advancing Agent, without any further act,
            deed or conveyance, shall become vested with all the rights, powers, trusts, duties and obligations of the retiring Advancing Agent hereunder and under the Servicing Agreement.

        

        

        (b)          No appointment of a successor Advancing Agent
            shall become effective unless (1) the Rating Agency Condition has been satisfied with respect to the appointment of such successor Advancing Agent and (2) such successor has a long-term unsecured debt rating of at least “A2” by Moody’s, and
            whose short-term unsecured debt rating is at least “P-1” from Moody’s.

        

        

        Section 16.7          Removal and Replacement of Backup Advancing Agent.

        

        

        The Note Administrator shall replace any such successor Advancing Agent (excluding the Note Administrator in its capacity as Backup
            Advancing Agent) upon receiving notice that such successor Advancing Agent’s long-term unsecured debt rating at any time becomes lower than “A2” by Moody’s, and whose short-term unsecured debt rating becomes lower than “P-1” by Moody’s, with a
            successor Advancing Agent that has a long-term unsecured debt rating of at least “A2” by Moody’s, and whose short-term unsecured debt rating is at least “P-1” from Moody’s.

        Section 17.1          Collateral Interest Purchase Agreements.

        

        

        Following the Closing Date, unless a Collateral Interest Purchase Agreement is necessary to comply with the provisions of this
            Indenture, the Issuer may acquire Collateral Interests in accordance with customary settlement procedures in the relevant markets.  In any event, the Issuer (or the Collateral Manager on behalf of the Issuer) shall obtain from any seller of a
            Collateral Interest, all Loan Documents with respect to each Collateral Interest that govern, directly or indirectly, the rights and obligations of the owner of the Collateral Interest with respect to the Collateral Interest and any certificate
            evidencing the Collateral Interest.

        Section 17.2          Representations and Warranties Related to Reinvestment Collateral Interests and Exchange Collateral Interests.

        

        

        (a)          Upon the acquisition of any Collateral Interest
            by the Issuer, the  Seller shall be required to make representations and warranties substantially in the form attached as Exhibit B to the Collateral Interest Purchase
            Agreement with such exceptions as may be relevant.

        

        

        (b)         The representations and warranties in Section 17.3 with respect to the acquisition of any Reinvestment Collateral Interest and Exchange
            Collateral Interest may be subject to any modification, limitation or qualification that the Collateral Manager determines to be reasonably acceptable in accordance with the Collateral Management Standard; provided that the Collateral Manager will provide the Rating Agencies with a report attached to each
            Monthly Report identifying each such affected representation or warranty and the modification, exception, limitation or qualification received with respect to the acquisition of any Reinvestment Collateral Interest and Exchange Collateral
            Interest during the period covered by the Monthly Report, which report may contain explanations by the Collateral Manager as to its determinations.

        

        

        (c)         The Issuer (or the Collateral Manager on behalf
            of the Issuer) shall obtain a covenant from the Person making any representation or warranty to the Issuer pursuant to Section 17.3(a) that such Person shall
            repurchase the related Collateral Interest if any such representation or warranty is materially breached (but only after the expiration of any permitted cure periods and failure to cure such breach).  The purchase price for any Collateral
            Interest repurchased shall be a price equal to the sum of the following (in each case, without duplication) as of the date of such repurchase:  (i) the then outstanding Principal Balance of such Collateral Interest, discounted based on the
            percentage amount of any discount that was applied when such Collateral Interest was purchased by the Issuer, plus (ii) accrued and unpaid interest on
            such Collateral Interest, plus (iii) any unreimbursed advances made under the Indenture or the Servicing Agreement on the Collateral Interest, plus (iv) accrued and unpaid interest on advances made under the Indenture or the Servicing Agreement on the Collateral Interest, plus (v) any reasonable costs and expenses (including, but not limited to, the cost of any enforcement action, incurred by the Issuer or the Trustee in connection with any
            such repurchase), plus (vi) any Liquidation Fee payable to the Special Servicer in connection with a repurchase of the Collateral Interest by the
            Seller.

        

        

        Section 17.3          Operating Advisor.

        

        

        If the Issuer, as a holder of a Pari Passu Participation has the right pursuant to the related Loan Documents to appoint the operating
            advisor, directing holder or Person serving a similar function under the Loan Documents, each of the Issuer, the Trustee and the Collateral Manager shall take such actions as are reasonably necessary to appoint the Collateral Manager to such
            position.

        LIBOR

        

        

        Calculation of LIBOR

        

        

        For purposes of calculating the London Interbank Offer Rate (“LIBOR”),





            the Issuer and the Co-Issuer shall initially appoint the Note Administrator as calculation agent (in such capacity, the “Calculation Agent”).  LIBOR with respect to
            any Interest Accrual Period shall be determined by the Calculation Agent in accordance with the following provisions:

        

        

        1.           On the second London Banking
            Day preceding the first Business Day of an Interest Accrual Period (each such day, a “LIBOR Determination Date”), LIBOR (other than for the initial Interest Accrual
            Period) shall equal the rate, as obtained by the Calculation Agent, for deposits in U.S. Dollars for a period of one month, which appears on the Reuters Page LIBOR01 (or such other page that may replace that page on such service for the purpose
            of displaying comparable rates) as reported by Bloomberg Financial Markets Commodities News as of 11:00 a.m., London time, on the LIBOR Determination Date.  “London Banking Day”
            means any day on which commercial banks are open for general business (including dealings in foreign exchange and foreign currency deposits) in London, England.

        

        

        2.            If, on any LIBOR
            Determination Date, such rate does not appear on Reuters Screen LIBOR01, the Calculation Agent shall determine LIBOR (or in the event the Notes convert to the Substitute Index, the Substitute Index) on the basis of the rates at which deposits
            in U.S. Dollars are offered by Reference Banks at approximately 11:00 a.m. (London time) on the LIBOR Determination Date to prime banks in the London interbank market for a period of one month commencing on the LIBOR Determination Date and in a
            representative amount of $1,000.  The Calculation Agent shall request the principal London office of each of the Reference Banks to provide a quotation of its rate.  If at least two such quotations are provided, the rate for that LIBOR
            Determination Date shall be the arithmetic mean of the quotations.  If fewer than two quotations are provided as requested, the rate for that LIBOR Determination Date shall be the arithmetic mean of the rates quoted by major banks in New York
            City, selected by the Calculation Agent, at approximately 11:00 a.m. (New York City time) on the LIBOR Determination Date for loans in U.S. Dollars to leading European banks for a period of three months commencing on the LIBOR Determination
            Date and in a representative amount of $1,000.  As used herein, “Reference Banks” means four major banks in the London interbank market selected by the Calculation
            Agent.

        

        

        3.            In respect of the initial
            Interest Accrual Period, LIBOR shall be determined on the second London Banking Day preceding the Closing Date.

        

        

        4.            Notwithstanding the
            foregoing, in no event will LIBOR be less than zero.

        

        

        If the Servicer effects a conversion with respect to at least 50% of the Real Estate Loans by Stated Principal Balance to an
            alternative or substitute index (the “Substitute Index”) in accordance with the related Loan Documents, then the Servicer will provide to the Note Administrator notice
            of such conversion in accordance with the Servicing Agreement and such Substitute Index plus a Substitute Index Spread Adjustment determined at the time of conversion shall be used in lieu of LIBOR to calculate interest with respect to the
            Notes of each Class beginning on the Payment Date that is at least three (3) Business Days after receipt of such notice or such later Payment Date upon which such conversion under the Real Estate Loans will be effective.

        

        

        
          
            


        

        In making the above calculations, (A) all percentages resulting from the calculation (other than the calculation determined pursuant
            to clause (c) above) will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point (0.00001%) and (B) all percentages determined pursuant to clause (c) above shall be rounded, if necessary, in accordance with the
            method set forth in (A), but to the same degree of accuracy as the two rates used to make the determination (except that such percentages will not be rounded to a lower degree of accuracy than the nearest one thousandth of a percentage point
            (0.001%)).

        

        

        “Substitute Index Spread Adjustment” means, with
            respect to any Class of Notes, either (i) a rate modifier associated with the Substitute Index that is published by a governmental or other source that is generally accepted as authoritative in the commercial real estate industry as reasonably
            determined by the Collateral Manager or (ii) if no such rate modifier is then available,  the average difference (expressed as the number of basis points) between (x) LIBOR and (y) the Substitute Index over the 60-days (or such shorter period
            for which all relevant indices are available) immediately preceding the LIBOR Determination Date on which the Notes convert to accrue interest based on the Substitute Index (or such earlier date on which LIBOR was last available).
