        ARTICLE 1

          

          Definitions and Incorporation by Reference

         

        SECTION 1.01.  Definitions. 

         

        “Additional Notes” means Notes issued under this Indenture after
          the Issue Date and in compliance with Section 2.12, it being understood that any Notes issued in exchange for or replacement of any Note issued on the Issue Date shall not be an Additional Note.

         

        “Affiliate” of any specified Person means any other Person, directly or indirectly, controlling or controlled by or under direct or indirect common control with such specified
          Person. For the purposes of this definition, “control” when used with respect to any Person means the power to direct the management and policies of such Person, directly or indirectly, whether through the
          ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing.

         

        “Applicable Procedures” means, with respect to any selection of Notes, transfer or exchange of or for beneficial interests in any Global Note, the rules and procedures of DTC,
          Euroclear Bank SA/NV and/or Clearstream Banking, S.A. that apply to such selection, transfer or exchange.

         

        “Attributable Debt” in respect of a Sale/Leaseback Transaction means,





          as at the time of determination, the present value (discounted at the interest rate borne by the Notes, compounded
          annually) of the total obligations of the lessee for rental payments during the remaining term of the lease included in such Sale/Leaseback













            Transaction (including any period for which such lease has been extended) (other than amounts required to be paid on account of property taxes, maintenance, repairs,
          insurance, water rates and other items which do not constitute payments for property rights); provided, however, that if such Sale/Leaseback Transaction results in a Capital Lease Obligation, the amount of indebtedness













          represented thereby will be determined in accordance with the definition of “Capital Lease Obligation.”

         

        “Board of Directors” means the Board of Directors of the Company or any committee or subcommittee thereof duly authorized to act on behalf of such Board, unless otherwise
          noted.

          authorized or required by law to close in New York City or the place of payment.

         

        
          
            


        

        
        “Capital Lease Obligation” means an obligation that is required to be classified and accounted for as a capital lease for financial
          reporting purposes in accordance with GAAP, and the amount of indebtedness represented by such obligation shall be
          the capitalized amount of such obligation determined in accordance with GAAP; and the Stated Maturity thereof shall
          be the date of the last payment of rent or any other amount due under such lease prior to the first date upon which such lease may be terminated by the lessee without payment of a
          penalty. For purposes of Section 4.04, a Capital Lease Obligation will be deemed to be secured by a Lien on the
          property being leased. Notwithstanding the foregoing, no lease will be deemed a “Capital Lease Obligation” for any purpose under this Indenture if such lease would not, as of December 31, 2015, have been required to be capitalized and reflected
          as a liability on a balance sheet in accordance with GAAP.

         

        “Capital Stock” of any Person means any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interests in (however designated) equity of such Person, including any preferred stock, but excluding any debt securities convertible or
          exchangeable into such equity.

         

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

          provision) is or becomes the beneficial owner (as such term is used in Rules 13d-3 and 13d-5 under the Exchange Act or any successor provision), directly or indirectly, of more than 50% of the total voting power of the Voting Stock of the
          Company; or

         

        (2)          the amalgamation, merger or consolidation of the Company with or into another Person or the merger of another Person with or into the Company
          or the sale of all or substantially all the assets of the Company (determined on a consolidated basis) to another Person, other than a transaction following which holders of securities that represented 100% of the Voting Stock of the Company
          immediately prior to such transaction (or other securities into which such securities are converted as part of such transaction) own, directly or indirectly, at least a majority of the voting power of the Voting Stock of the surviving or
          transferee Person in such transaction immediately after such transaction.

         

        Notwithstanding the foregoing, a transaction will not be deemed to involve a “Change of Control” if: (i) (a)
            the Company becomes a direct Subsidiary of a holding company and (b)(x) upon completion of such transaction, the direct or indirect holders of the Voting Stock of such holding company own such Voting Stock in substantially the same proportion
            as the holders of the Voting Stock of the Company immediately prior to that transaction or (y) holders of securities that represented 100% of the Voting Stock of the Company immediately prior to such transaction (or other securities into which
            such securities are converted as part of any amalgamation, merger or consolidation transaction) own, directly or indirectly, at least a majority of the voting power of the Voting Stock of such holding company immediately after such transactions
            or (ii) any wholly owned Subsidiary of a company with a class or series of Voting Stock that is traded on a national securities exchange (a “Public Company”) acquires, amalgamates with, merges with or
            consolidates with the Company and an amalgamation, merger or consolidation of the Public Company with the Company would not otherwise have constituted a Change of Control under clause (1) or (2) of the definition of “Change of Control” above.

Each Note shall be dated the date of its authentication. The terms of the Notes set forth in the Appendix are part of the terms of this Indenture. 

         

        SECTION 2.02.  Execution and Authentication. One Officer shall sign the Notes for the Company by manual, electronic or facsimile signature. 

         

        If an Officer whose signature is on a Note no longer holds that office at the time
          the Trustee authenticates the Note, the Note shall




          be valid nevertheless.

          certificate of authentication on the Note by manual signature. The signature shall be conclusive evidence that the Note has













          been authenticated under this Indenture.

          amount specified in such order, in each case upon a written order of the Company signed by one Officer of
          the Company (a “Company Order”). Such order shall specify the amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated.

        The Trustee may appoint an authenticating agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Responsible Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such
          appointment, the Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in
          this Indenture to authentication by the Trustee includes authentication by such agent. The Authenticating Agent
          has the same rights as any Registrar, Paying Agent or agent





          for service of notices and demands.

         

        The Trustee and the Authenticating Agent shall have the right to decline to authenticate and deliver any Notes under this Section 2.02 if the Trustee in good faith determines that such action may not lawfully be
          taken or if the Trustee in good faith determines that such action would expose the Trustee or the Authenticating Agent to personal liability, unless indemnity or security satisfactory to the Trustee or the Authenticating Agent, as applicable,
          against such liability is provided to the Trustee or the Authenticating Agent, as applicable.

         

        SECTION 2.03.  Registrar and













          Paying Agent. 

         

        (a)          The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for
          exchange (the “Registrar”) and an office or agency where Notes may be presented for payment (the “Paying Agent”). The Registrar




          shall keep a register of the Notes and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes any additional paying agent.

         

        (b)          The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and
          address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate
          compensation therefor pursuant to Section 7.07. The Company or any Wholly Owned Subsidiary incorporated or organized within the United States of America may
          act as Paying Agent, Registrar, co-registrar or transfer




          agent.

         

        (c)          The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor Registrar or Paying Agent, as the case may be, as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance
          with Section 2.03(c)(i). The Registrar or Paying Agent may resign at any time upon written notice to the Company and the Trustee; provided, however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08.

         

        (d)          The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Notes.

         

        
          11

          
            


        

        SECTION 2.04.  Paying Agent To Hold Money in Trust. Prior to each due date of the principal and interest on any Note, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Noteholders or the Trustee all money held by
          the Paying Agent for the payment of principal of or interest on the Notes and shall notify the Trustee of












          any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying
            Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company
          at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any
          funds disbursed by the Paying Agent. Upon complying with this Section 2.04, the Paying Agent shall have no further
          liability for the money delivered to the Trustee. 

         

        SECTION 2.05.  Noteholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Noteholders. If the Trustee is not the Registrar, the Company shall
          furnish, or cause the Registrar to furnish, to the Trustee,
          in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the
          names and addresses of Noteholders. 

         

        SECTION 2.06.  Transfer and Exchange. (a) The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note





          for registration of transfer. When a Note is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall
          register the transfer as requested if the requirements of this Indenture and Section 8-401(1) of the Uniform Commercial
            Code are met. When Notes are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall register the transfer or make the exchange as requested if the same requirements are met. The Company may require payment of a sum sufficient to pay all taxes, assessments and
          other governmental charges in connection with any transfer or exchange pursuant to this Section 2.06. The Company shall




          not be required to make, and the Registrar need not register, transfers or exchanges of Notes selected for redemption (except, in the case of Notes to be redeemed in part, the portion thereof not to be redeemed) or of any Notes for a period of 15 days before a
          selection of Notes to be redeemed, or between a record date and the related payment date. 

         

        Prior to the due presentation for registration of transfer of any Note, the Company,
          the Trustee, the Paying Agent and the Registrar may





          deem and treat the person in whose name a Note is registered as the absolute owner of such Note for all purposes of receiving payment of principal of and interest, if
          any, on such Note and for all other purposes whatsoever, whether or not such security is overdue, and none of the
          Company, the Trustee, a Paying Agent or the Registrar shall be affected by notice to the contrary.

         

        All securities issued upon any transfer or exchange pursuant to the terms of this Indenture
          shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Notes surrendered




          upon such transfer or exchange.

         

        (b)          Any Registrar appointed pursuant to Section 2.03 shall provide the Trustee such information as the Trustee may
          reasonably require in connection with the delivery by such Registrar of Notes upon transfer or exchange of Notes.

         

        
          12

          
            


        

        (c)          The Trustee shall have no obligation or





          duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture





          or under applicable law with respect to any transfer of any interest in any Note between or among any member of, or participant in, The Depository Trust Company (“DTC”) (or any













          other securities clearing agency that is registered as such under the Exchange Act and is designated by the Company to













          act as a depository for such Notes) or other beneficial owners of interests in any Global Note other than to
          require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.  None of the Company, Trustee, Registrar or Paying Agent shall
          have any responsibility for any actions taken or not taken by DTC.

         

        SECTION 2.07.  Replacement Notes.
          If a mutilated Note is surrendered to the Registrar or if












          the Holder of a Note claims that the Note has
          been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall, upon receipt of a Company Order, authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder (a) provides
            evidence satisfactory to the Company or the Trustee




            of such loss, destruction or wrongful taking within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Company or the Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “Protected Purchaser”) and (c) satisfies any other
          reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company, with respect to the Company, and the Trustee, with respect to the Trustee, to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss or liability which any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note (including
          attorneys’ fees and disbursements in replacing such security). In the event any such mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may
          pay such Note instead of issuing a new Note in replacement thereof. 

         

        Every replacement Note is an additional obligation of the Company.

         

        SECTION 2.08.  Outstanding Notes.
          Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Subject to Section 11.05, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 

         

        If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless
          the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a Protected Purchaser.

         

        If the Paying Agent segregates and holds in trust, in accordance with this Indenture,
          on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions
          thereof) to be redeemed or maturing, as the case may be, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

         

        
          13

          
            


        

        SECTION 2.09.  Temporary Notes. Until Definitive Notes are ready for delivery, the Company may prepare and, upon receipt of a Company Order, the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in
            the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes and deliver them in exchange for temporary Notes at












            the office or agency of the Company. 

         

        SECTION 2.10.  Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration of transfer, exchange, payment or cancellation in accordance with its customary procedures for the disposition of canceled securities and deliver a certificate of such disposition to the Company unless the Company directs the Trustee to deliver canceled Notes to the Company. The Company may not issue new
          Notes to replace Notes it has redeemed, paid or delivered




          to the Trustee for cancellation. 

         

        SECTION 2.11.  CUSIP Numbers, ISINs, etc. The Company in issuing the Notes may use “CUSIP” numbers, “ISINs” and “Common Code” numbers (in
          each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, “ISINs” and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation
          is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a
          redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly advise the Trustee in writing of any change in any “CUSIP” numbers, “ISINs” or “Common Code” numbers applicable to the Notes. 

         

        SECTION 2.12.  Issuance of Additional













              Notes. After the Issue Date, the Company shall be entitled to issue Additional Notes under this Indenture, which Notes shall have identical
          terms as the Notes issued on the Issue Date, other than with respect to the date of issuance, issue price and, if
          applicable, the first interest payment date; provided that if any such Additional Notes are not fungible with the Notes issued on the Issue Date for U.S. federal income tax purposes, such Additional Notes
          will have one or more separate CUSIP numbers from the Notes issued on the Issue Date. All the Notes issued under this Indenture













          shall be treated as a single class for all purposes of this Indenture including waivers, amendments,
          redemptions and offers to purchase. 

         

        With respect to any Additional Notes, the Company shall set forth in a resolution of
          the Board of Directors and an Officer’s Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

         

        (1)          the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; and

         

        
          14

          
            


        

        (2)          the issue price, the issue date and the “CUSIP” number of such Additional Notes.

         

        SECTION 2.13.  Defaulted Interest.  If the Company defaults in a payment of interest on the Notes, the Company shall pay the defaulted
          interest then borne by the Notes to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Note. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be
          paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make
          arrangements reasonably satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this
          Section 2.13. The Company shall fix or cause to be fixed each such special record date and payment date. The Company shall promptly notify the Trustee in writing of such special record date and shall, or at the written request and in the name and
          expense of the Company, the Trustee shall, cause notice of the proposed payment of such defaulted interest and the special record date and payment date therefor to be given in the manner provided for in Section 11.01, not less than 10 days prior
          to such special record date. The Company may pay defaulted interest in any other lawful manner. 

         

        

        

        ARTICLE 3

          

          Redemption

         

        SECTION 3.01.  Selection of Notes













            to Be Redeemed. If fewer than all the Notes are to be redeemed, the Trustee shall select the Notes to be redeemed on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and
          appropriate; provided, however, that Global Notes shall be selected in accordance with the Applicable Procedures of DTC. The Trustee shall make the selection from outstanding Notes not previously called for redemption. The Trustee may select for redemption portions of the principal of Notes that have
          denominations larger than $2,000. Notes and portions of them the Trustee selects shall be in minimum













          principal amounts of $2,000 or whole multiples of $1,000 in excess of $2,000.
          Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company




          promptly of the Notes or portions of Notes to




          be redeemed. 

         

        SECTION 3.02.  Notice of Redemption. Not less than 10 days nor more than 60 days prior to a redemption date for the Notes, the Company shall mail or cause to be mailed a notice of redemption by first-class mail (or delivered by electronic
          transmission in accordance with the Applicable Procedures of DTC) to each Holder of Notes (with a copy of such
          notice to the Trustee) to be redeemed at such Holder’s registered address, except that redemption notices may be
          mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. 

         

        Notice of any redemption of any Notes in connection with a transaction or an event (including a Change of Control Triggering Event or a new financing) may, at the Company’s discretion, be given prior to the
          completion or the occurrence thereof, and any such redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of the related transaction or event.

         

        
          15

          
            


        

        The notice shall identify the Notes to be redeemed and shall state:

         

        (1)          the redemption date;

         

        (2)          the redemption price and the amount of accrued and unpaid interest to, but excluding, the redemption date;

         

        (3)          the name and address of the Paying Agent;

         

        (4)          that Notes called for redemption must be surrendered
          to the Paying Agent to collect the redemption price, plus accrued and unpaid interest, if any;

         

        (5)          if fewer than all the outstanding Notes are to be
          redeemed, the certificate numbers and principal amounts of the particular Notes to be redeemed, the aggregate
          principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption;

         

        (6)          that, unless the Company defaults in making such
          redemption payment, interest on Notes (or portion
          thereof) called for redemption ceases to accrue on and after the redemption date;

         

        (7)          the “CUSIP” number, “ISIN” and/or “Common Code”
          number, if any, printed on the Notes being redeemed; and

         

        (8)          that no representation is made as to the correctness or accuracy of the “CUSIP” number, “ISIN,” and/or “Common Code” number, if any, listed in such notice or printed on the Notes.

         

        In addition, if such redemption is subject to one or more conditions precedent, such notice shall describe each such condition and, if applicable, shall state that, in the Company’s discretion, the redemption date
          may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied (or waived by the Company in its
          sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. Upon receipt of such
          notice from the Company rescinding such redemption, the Trustee will promptly send a copy of such notice to the Holders of the Notes to be redeemed in the same manner in which the notice of redemption was given.

         

        At the Company’s written request, delivered at least 15 days before the date such
          notice is to be given to the Holder (unless a shorter period shall be acceptable to the Trustee), the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with
          the information required by this Section 3.02.

         

        
          16

          
            


        

        SECTION 3.03.  Effect of Notice of Redemption. Once notice of
            redemption is mailed or delivered in accordance with the Applicable Procedures of DTC, Notes called for redemption become due and payable on the redemption date (unless such
            redemption is conditioned on the happening of a future event, in which case the Note is due on the date the conditions set forth in the notice of redemption have been satisfied or waived) and at the redemption price stated in the notice. Upon
            surrender to the Paying Agent, such Notes shall be paid at the redemption price stated in the notice, plus
            accrued and unpaid interest to, but excluding, the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment












            date), and such Notes shall be canceled by the Trustee. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 

         

        SECTION 3.04.  Deposit of Redemption Price. Prior to 10:00 a.m., New York City time, on
          the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Wholly Owned Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of, and accrued and unpaid interest on, all the Notes to be redeemed on that date other than Notes or portions of Notes called for redemption which have been delivered by the Company to the Trustee for cancellation. 

         

        SECTION 3.05.  Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company shall execute and the Trustee shall authenticate for the
          Holder (at the Company’s expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 

         

        SECTION 3.06.  Optional Redemption. 

         

        (a)          At any time prior to April 15, 2030 (three months before the maturity date of the Notes) (the “Par Call Date”), the Company may, at its option, redeem some or all of the Notes at any time and from time to time upon notice pursuant to Section 3.02 at a redemption price (the “Make-Whole Redemption Price”) equal to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but excluding, the redemption date.

         

        (b)          The Make-Whole Redemption Price will be calculated assuming a 360-day year
            consisting of twelve 30-day months.  For purposes of calculating the Make-Whole Redemption Price, the following terms will have the meanings set forth below:

         

        “Adjusted Treasury Rate” means, with respect to a Note at any redemption date, subject to a 0% floor, (1) the yield, under the heading which represents the average for the
          immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields
          on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or
          after the Par Call Date, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight
          line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent
          yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in each case calculated on the third Business Day immediately preceding the
          date that the applicable redemption notice is first mailed or sent, in the case of each of clauses (1) and (2), plus 35 basis points.

         

        
          17

          
            


        

        “Applicable Premium” means with respect to a Note at any redemption date, as provided by the Company, the excess of (1) the present value at such redemption date of the
          Remaining Scheduled Payments on such Note (but excluding accrued and unpaid interest, if any, to, but excluding, the redemption date), computed using a discount rate equal to the Adjusted Treasury Rate, over (2) the principal amount of such Note
          on such redemption date.

         

        “Comparable Treasury Issue” means the United States Treasury security selected by the
          Quotation Agent as having a maturity comparable to the remaining term of the Notes from the redemption date to the Par Call Date, that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new
          issues of corporate debt securities of a maturity most nearly equal to the Par Call Date.

         

        “Comparable Treasury Price” means, with respect to a Note at any redemption date, if clause
          (2) of the Adjusted Treasury Rate definition is applicable,

         

        (1)          the average of the Reference Treasury Dealer Quotations for that redemption
          date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations;

         

        (2)          if the Company obtains fewer than four Reference













            Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received; or

         

        (3)          if only one Reference Treasury Dealer Quotation is received, such quotation.

         

        “Quotation Agent” means one of the Reference Treasury Dealers selected by the Company.

         

        “Reference Treasury Dealer” means each of four primary U.S. Government securities













          dealers in New York City (each a “Primary Treasury Dealer”), consisting of (i) J.P. Morgan Securities LLC (or its affiliate), (ii)
          Citigroup Global Markets Inc. (or its affiliate) and (iii) two other nationally recognized investment banking firms (or their




          affiliates) that the Company selects in connection with the particular redemption, and their respective successors; provided that if any
          of them ceases to be a Primary Treasury Dealer, the Company will substitute another nationally recognized investment banking firm (or its affiliate) that is a
          Primary Treasury Dealer.

         

        “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average,
          as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at
          3:30 p.m., New York City time, on the third Business Day preceding the date that the applicable redemption notice is first mailed or sent.

         

        
          18

          
            


        

        “Remaining Scheduled Payments” means the remaining payments of principal of and interest on the Notes that would be due after the redemption date but for such redemption if
          the Notes matured on the Par Call Date. If the redemption date is not an interest payment date, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued thereon to the redemption
          date.

         

        (c)          Except pursuant to Section 3.06(a), the Notes shall not be redeemable at the Company’s option prior to the Par Call Date.

         

        (d)          At any time on or after the Par Call Date, upon notice pursuant to Section
          3.02, the Company may, at its option, redeem some or all of the Notes at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the applicable redemption date.

         

        (e)          Any redemption pursuant to this Section 3.06 shall be made in a manner
          consistent with the provisions of Sections 3.01 through 3.05 hereof to the extent applicable.

         

        (f)          Notwithstanding the foregoing, in connection with any offer to purchase or tender offer for the Notes at any time, if Holders of not less than 90% in aggregate
          principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such offer and the Company, or any third party making such tender offer in lieu of the Company, purchases all of the Notes validly tendered and not
          withdrawn by such Holders, the Company or such third party will have the right upon not less than 10 nor more than 60 days’ prior notice, given not more than 60 days following such purchase date, to redeem (with respect to the Company) or
          purchase (with respect to a third party) all Notes that remain outstanding following such purchase at a price equal to the price paid to each other Holder in such tender offer (which may be less than par) plus, to the extent not included in the
          tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the applicable redemption date or purchase date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant
          interest payment date falling on or prior to such redemption date or purchase date.

         

        (g)          Unless the Company defaults in the payment of the redemption price, on and after the applicable redemption date, interest













          will cease to accrue on the Notes or portions of the Notes called for redemption. If the optional redemption date is on or after an interest record date but on or prior to the
          related interest payment date, then any accrued and unpaid interest in respect of the Notes subject to redemption will be paid on the redemption date to the Person in whose name the note is registered at the close of business on such record date,
          and no additional interest will be payable to Holders whose Notes are redeemed by the Company.

         

        (h)          Calculation of the redemption price will be made by the Company or on the Company’s behalf by such person as the Company shall designate; provided that such calculation or the correctness thereof shall not be a duty or obligation of the Trustee.

        SECTION 4.01.  Payment of Notes.
          The Company shall promptly pay the principal of and interest












          on the Notes on the dates and in the manner provided in the Notes and in this Indenture. Principal and interest shall be considered paid on the date due
          if on such date the Trustee or the Paying Agent holds

        The Company shall pay interest on overdue principal at the rate specified therefor in the Notes, and it shall pay interest on
          overdue installments of interest at the same rate to the extent lawful.

         

        SECTION 4.02.  SEC Reports. 

        

        

        (a)          So long as any Notes are outstanding, the Company will












          furnish to the Trustee:

         

        

        (1)          within 90 days after the end of each fiscal year (or such longer period as
          may be permitted by the SEC if the Company were then subject to SEC reporting requirements as a non-accelerated filer), annual reports of the Company containing substantially all
          of the information that would have been required to be contained in an Annual Report on Form 10-K under the Exchange Act if





          the Company had been a reporting company under the Exchange Act (but only to the extent similar information was included in the Offering Memorandum), including (A) “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and (B) audited financial statements prepared in accordance with GAAP or, to the extent the Company is a reporting company, the Annual Report on Form 10-K as filed under the Exchange Act;

         

        (2)          within 45 days after the end of each of the first three fiscal quarters of
          each fiscal year (or such longer period as may be permitted by the SEC if the Company were then subject to SEC reporting requirements as a non-accelerated filer), quarterly reports of the Company













          containing substantially all of the information that would have been required to be contained in a Quarterly Report on Form 10-Q under the Exchange Act if the Company had been a reporting company under the Exchange Act (but only to the extent similar information was provided in the Offering Memorandum),
          including (A) “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and (B) unaudited quarterly financial statements prepared in accordance with GAAP and reviewed pursuant to AU 722, Interim Financial Information (or any
          successor provision) or, to the extent the Company is a reporting company, the Quarterly Report on Form 10-Q as filed under the Exchange Act; and

         

        (3)          within five Business Days after the date upon which a Current Report on Form
          8-K would be required to be filed as a result of the occurrence of an event that would have been required to be reported in a Current Report on Form 8-K under the Exchange Act if the Company had been a reporting company under




          the Exchange Act, current reports containing substantially all of the information that would have been required to be contained in a Current Report on Form 8-K under the Exchange Act if the Company had been a reporting company under




          the Exchange Act; provided, however, that no such current report will be required to be furnished if the Company determines in its good faith judgment that such event is
          not material to Holders or the business, assets, operations, financial positions or prospects of the Company and its Subsidiaries, taken as a whole, or could result in material competitive harm;

         

        
          20

          
            


        

        provided, however, that such reports (A) will not be required to comply with Section 302 or Section 404 of the Sarbanes-Oxley Act of 2002, or related Items 307 and 308 of Regulation S-K promulgated by the SEC, or Item 10(e) of Regulation S-K (with respect to any non-GAAP financial measures
            contained therein) and (B) will not be required to contain the separate financial information for Guarantors contemplated by Rule 3-10 or Rule 3-16 of Regulation S-X promulgated by the SEC.

         

        (b)          The availability of the foregoing materials on the SEC’s EDGAR service or the posting thereof on a public website shall be deemed to
          satisfy the delivery obligation of the Company. For the avoidance of doubt, the Trustee shall have no obligation to monitor or confirm, on a continuing basis or otherwise, whether
          the Company posts such reports, information and documents on the SEC’s EDGAR service or on any public website, or collect any such reports, information and documents from the SEC’s EDGAR service or any public website.

         

        (c)          Notwithstanding the foregoing, the Company may satisfy its obligations under this Section 4.02 with respect to financial and other information of the Company by
          furnishing (A) the applicable financial statements of any parent entity of the Company or (B) to the extent the parent entity is a reporting company, any parent entity’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q or Current
          Reports on Form 8-K, as applicable; provided that, to the extent that in the reasonable judgment of the Company, there are material differences between the financial information of the Company, on the one
          hand, and the parent entity, on the other hand, the same is accompanied by consolidating information, which may be posted to the website of the Company or any direct or indirect parent of the Company or on a non-public, password-protected website
          maintained by the Company, any direct or indirect parent of the Company or a third party, that explains in reasonable detail the material differences between the information relating to such parent entity, on the one hand, and the information
          relating to the Company and its Subsidiaries on a standalone basis, on the other hand. For the avoidance of doubt, the consolidating information referred to in the proviso in the preceding sentence need not be audited or reviewed.

         

        (d)          Notwithstanding the foregoing, to the extent the Company or any direct or indirect parent of the Company does not file reports with the SEC’s EDGAR service, the
          Company shall make the reports required by this covenant available to the Holders of Notes, beneficial owners of Notes, bona fide prospective investors in the Notes, bona fide market makers in the Notes affiliated with any Initial Purchaser and
          bona fide securities analysts (to the extent providing analysis of investment in the Notes) by posting to the website of the Company or any direct or indirect parent of the Company or on a non-public, password-protected website maintained by the
          Company or any direct or indirect parent of the Company or a third party, in each case, within 15 days after the time the Company would be required to provide such information pursuant to clauses (1), (2) or (3) of Section 4.02(a), as applicable.

         

        
          21

          
            


        

        (e)          In addition, the Company shall furnish to Holders,
          prospective investors, broker-dealers and securities analysts, upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities





            Act.

         

        (f)          To the extent any such information is not provided within the time periods specified in this Section 4.02 and such information is subsequently provided, the
          Company will be deemed to have satisfied its obligations with respect thereto at such time and any Default or Event of Default with respect thereto shall be deemed to have been cured.

         

        (g)          Delivery of reports, information and documents to the Trustee is for informational purposes only, and its receipt of such reports, information and documents
          shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s, any Guarantors’ or any other Person’s compliance with any of its covenants under this
          Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on the Officer’s Certificates delivered pursuant to this Indenture). The Trustee shall have no liability or responsibility for the content, filing or timeliness of
          any report delivered or filed under or in connection with this Indenture or the transactions contemplated thereunder.

         

        SECTION 4.03.  Change of Control. 

         

        (a)          Within 30 days following the occurrence of a Change of Control Triggering Event
            with respect to the Notes, each Holder shall have the right to require that the Company make an offer to
          purchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase plus accrued and unpaid interest, if any, to, but excluding, the
          date of purchase, in accordance with the terms contemplated in Section 4.03(b). If the Change of Control purchase date is on or after an interest record date and on or before the
          related interest payment date, any accrued and unpaid interest to the Change of Control purchase date will be paid on the Change of Control purchase date to the Person in whose name a Note is registered at the close of business on such record
          date.

         

        (b)          Within 30 days following the occurrence of a Change of Control Triggering Event with respect to the Notes, unless the Company has exercised its option to redeem all the Notes pursuant to Section 3.06, the Company shall mail (or deliver by electronic transmission in accordance with the Applicable Procedures of DTC) a notice to each Noteholder with a copy to the Trustee (the “Change of Control Offer”) stating:

         

        (1)          that a Change of Control Triggering Event has occurred and that such Noteholder has the right to require the Company to purchase such Noteholder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to but excluding the date of purchase;

         

        (2)          the circumstances that constitute or may constitute such Change of Control
            Triggering Event;

         

        
          22

          
            


        

        (3)          the purchase date (which shall be no earlier than 10 days nor later than 60 days from the date such notice is sent); and

         

        (4)          the instructions, as determined by the Company, consistent with this Section
          4.03, that a Noteholder must follow in order to have its Notes purchased.

         

        (c)          Holders electing to have a Note purchased under this Section 4.03 will be required to surrender the Note, with an
          appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior




          to the purchase date. Holders will be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the purchase date, a telegram, facsimile transmission or letter setting
          forth the name of the Holder, the principal amount of the Note




          which was delivered for purchase by the Holder and a statement that such Holder is withdrawing its election
          to have such Note purchased.

         

        (d)          On the purchase date, all Notes purchased













          by the Company under this Section 4.03 shall be delivered by the Company to the Trustee for cancellation, and in accordance with Section 4.03(a), the Company shall pay the purchase price plus accrued and unpaid interest, if any, to the Holders entitled thereto.

         

        (e)          Notwithstanding the foregoing provisions of this Section 4.03, the Company shall not be required to make a Change of Control Offer following a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance
          with the requirements set forth in this Section 4.03 applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or if the Company has exercised its option to redeem all the Notes pursuant to Section 3.06.

         

        (f)          If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a
          Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party
          will have the right, upon not less than 10 nor more than 60 days’ prior notice (provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer as
          set forth above) to redeem (with respect to the Company) or purchase (with respect to a third party) all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the aggregate principal amount of such Notes, plus
          accrued and unpaid interest, if any, on the Notes that remain outstanding to, but excluding, the date of redemption or the date of purchase, subject to the right of Holders of record on the relevant record date to receive interest due on the
          relevant interest payment date falling on or prior to the redemption date or purchase date.

         

        (g)          The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of
          the Exchange Act and any other securities laws or regulations in connection with the purchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.03, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.03 by virtue of its compliance with such securities laws or regulations.

         

        
          23

          
            


        

        (h)          Notwithstanding anything to the contrary in this Section 4.03, a Change of Control Offer may be made in advance of a Change of Control Triggering Event,
          conditioned upon such Change of Control Triggering Event. In such case, the notice shall state that, in the Company’s discretion, the Change of Control purchase date may be delayed until such time as the Change of Control Triggering Event shall
          have occurred, or such repurchase may not occur and such notice may be rescinded in the event that the Change of Control Triggering Event shall not have occurred by the Change of Control purchase date, or by the Change of Control purchase date as
          so delayed.

         

        SECTION 4.04.  Limitation on Liens.
          (a) The Company will not, and will not permit any of its Subsidiaries to, create, incur, issue, assume or guarantee (collectively, “Incur”) any indebtedness for money borrowed evidenced by loans, bonds,
          notes, debentures, letters of credit or bankers’ acceptances, in each case to the extent such indebtedness would appear as a liability on the balance sheet of such Person in accordance with GAAP (“Debt”)
          secured by a Lien upon (a) any Property of the Company or such Subsidiary, or (b) any shares of Capital Stock, whether owned on the Issue Date or thereafter acquired, without effectively providing concurrently that the Notes then outstanding
          under this Indenture are secured equally and ratably with or, at the option of the Company, prior to such Debt so long as such Debt shall be so secured. 

        
           

          (b)          The foregoing restriction in Section 4.04(a) shall not apply to, and there shall be excluded from Debt (or any guarantee thereof) in any computation under Section 4.04(a) or 4.04(c), Debt (or any
            guarantee thereof) secured by:

           

          (1)          pledges, deposits or security by such Person under workmen’s compensation laws, unemployment

            adjustments thereto) or indemnification obligations of (including obligations in respect of letters of credit or bank guarantees for the benefit of) insurance carriers providing property, casualty or liability insurance, or good faith deposits in connection with bids, tenders, contracts (other than for the payment of Debt) or leases to which such Person is




            a party, or deposits to secure public or statutory obligations of such Person




              or deposits of cash or U.S. government bonds to secure surety or appeal bonds to which such Person is
            a party, or deposits as security for contested taxes or import duties or for the payment of rent, in each case
            Incurred in the ordinary course of business;

           

          (2)          Liens imposed by law, such as landlords’, carriers’, warehousemen’s, materialmen’s, repairmen’s
            and mechanics’ Liens, or other Liens arising out of judgments or awards against such Person with respect to which such Person shall then be proceeding with an appeal or other proceedings for review;

           

          (3)          minor survey exceptions, minor encumbrances, ground leases, easements or reservations of, or rights of others for, licenses, rights-of-way,
            servitudes, sewers, electric lines, drains, telegraph, telephone and cable television lines and other similar purposes, or zoning, building codes or other restrictions (including minor defects and irregularities in title and similar
            encumbrances) as to the use of real properties or Liens incidental to the conduct of the business of such Person or to the ownership of its properties which were not Incurred in connection with Debt and which do not in the aggregate materially
            impair their use in the operation of the business of such Person;

           

          
            24

            
              


          

          (4)          Liens on any property existing at the time of the acquisition thereof;

           

          (5)          Liens on property of a Person existing at the time such Person is amalgamated, merged into or consolidated with the Company or a Subsidiary
            of the Company or at the time of a sale, lease or other disposition of the properties of such Person (or a division thereof) as an entirety or substantially as an entirety to the Company or a Subsidiary of the Company; provided that any such Lien does not extend to any property owned by the Company or any Subsidiary of the Company immediately prior to such amalgamation, merger, consolidation, sale, lease or disposition;

           

          (6)          Liens on property of a Person existing at the time such Person becomes a Subsidiary of the Company;

           

          (7)          Liens in favor of the Company or a Subsidiary of the Company;

           

          (8)          Liens to secure all or part of the cost of acquisition, construction, development or improvement, including, but not limited to, in each
            case, work-in-process, tenant improvements and construction-in-progress assets, of the underlying property, or to secure Debt Incurred to provide funds for any such purpose; provided that the commitment
            of the creditor to extend the credit secured by any such Lien shall have been obtained no later than 365 days after the later of (a) the completion of the acquisition, construction, development or improvement of such property or (b) the placing
            in operation of such property; provided, further, that such Liens do not extend to any property other than such property subject to acquisition, construction,
            development or improvement and accessions thereto and improvements thereon;

           

          (9)          Liens in favor of any Governmental Authority to secure partial, progress, advance or other payments;

           

          (10)        Liens existing on the Issue Date or any extension, renewal, replacement or refunding of any Debt (or any guarantee thereof) secured by a Lien
            existing on the Issue Date or referred to in clauses (4)-(6) or (8); provided that the principal amount of the Debt (or any guarantee thereof) shall be created within 365 days of repaying the Debt (or
            any guarantee thereof) secured by the Lien referred to in clauses (4)-(6) or (8) and the principal amount of Debt (or any guarantee) secured thereby and not otherwise authorized by clauses (4)-(6) or (8) shall not exceed the principal amount of

            principal amount not to exceed $1,150.0 million.

           

          (c)          Notwithstanding the restrictions set forth in Section 4.04(a), the Company and any Subsidiaries of the Company may Incur Debt secured by Liens without equally and ratably securing the Notes then
            outstanding if, at the time of such Incurrence, after giving effect thereto and to the retirement of any Debt which is concurrently being retired, the aggregate amount of all such Debt secured by Liens which would otherwise be subject to such

          (a)          The Company shall not, and shall not permit any Subsidiary of the Company to, enter into any Sale/Leaseback Transaction with respect to any Property unless:

           

          (1)          the Sale/Leaseback Transaction is solely with the Company or another Subsidiary of the Company;

           

          (2)          the lease is for a period not in excess of 36 months (or which may be terminated by the Company or such Subsidiary), including renewals;

           

          (3)          the Company or such Subsidiary would (at the time of entering into such arrangement) be entitled as described in clauses (1)-(23) of Section
            4.04(b), without equally and ratably securing the Notes then outstanding under this Indenture, to Incur Debt secured by a Lien on such Property in the amount of the Attributable Debt arising from such Sale/Leaseback Transaction;

           

          (4)          the Company or such Subsidiary within 365 days after the sale of such Property in connection with such Sale/Leaseback Transaction is
            completed, applies an amount equal to the net proceeds of the sale of such Property to (a) the retirement of the Notes, other Funded Debt of the Company ranking on a parity with the Notes (or the Guarantees of the Notes) or Funded Debt of a

          (6)          (a)          the Attributable Debt of the Company and Subsidiaries of the Company in respect of such Sale/Leaseback Transaction and all
            other Sale/Leaseback Transactions on Properties entered into after the Issue Date (other than any such Sale/Leaseback Transaction as would be permitted as described in clauses (1)-(5) of this Section 4.05(a)), plus:

           

          
            27

            
              


          

          (b)          the aggregate principal amount of Debt secured by Liens then outstanding (not including any such Debt secured by Liens described in clauses (1)-(23) of Section 4.04(b)) that are not
            equally and ratably secured with the outstanding Notes (or secured on a basis junior to the outstanding Notes),

           

          at the time of Incurrence would not exceed the greater of (x) $170.0 million and (y) 20% of Consolidated Total Assets.

           

          (b)          For purposes of this Section 4.05, (i) in determining compliance with any U.S. dollar-denominated restriction on the entering into of any Sale/Leaseback Transaction, the U.S. dollar-equivalent
            principal amount of Attributable Debt denominated in a foreign currency shall be calculated based upon the relevant currency exchange rate in effect on the date such Attributable Debt in respect of such Sale/Leaseback Transaction was Incurred;
            provided, however, that if such Attributable Debt is Incurred to Refinance other Attributable Debt denominated in a foreign currency, and such Refinancing would cause the applicable U.S.
            dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such Refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the
            principal amount of such Refinancing Attributable Debt does not exceed the amount necessary to Refinance the principal amount of such Attributable Debt being Refinanced and (ii) the maximum amount of Attributable Debt that the Company or any
            Subsidiary may Incur in respect of any Sale/Leaseback Transaction shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies.

           

          SECTION 4.06.  Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year
            of the Company an Officer’s Certificate stating that in the course of the performance by the signer of his or
            her duties as an Officer of the Company, he or she would normally have knowledge of any Default and whether or not the signer knows of any Default that occurred
            during such period. If he or she does, the certificate shall describe the Default, its status and what action the Company
            is taking or proposes to take with respect thereto. 

           

          The Company shall deliver to the Trustee, as soon as possible and in any event
            within 30 days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officer’s




              Certificate setting forth the details of such Event of Default or default and the action which the Company proposes to take with respect thereto.

           

          SECTION 4.07.  Additional Guarantors.  The Company shall cause each Subsidiary of the Company that is a borrower under or is required to
            guarantee the Credit Agreement and that is organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, within 60 days of the date on which such Subsidiary becomes a borrower under the
            Credit Agreement or the Company becomes required to deliver a guarantee of the Credit Agreement pursuant to the terms thereof, to (1) execute and deliver to the Trustee a supplemental indenture substantially in the form of Annex 1 hereto,
            pursuant to which such Subsidiary shall unconditionally Guarantee all of the Company’s obligations under the Notes on the terms set forth in this Indenture and (2) deliver, within such 60-day period described in this Section 4.07, to the
            Trustee an Opinion of Counsel reasonably satisfactory to the Trustee that such supplemental indenture has been duly executed and delivered by such Subsidiary. The Company may elect, in its sole discretion, to cause any Subsidiary that is not
            otherwise required to be a Guarantor to become a Guarantor, in which case such Subsidiary shall not be required to comply with the 60-day period described in this Section 4.07.

          SECTION 4.08.  Limited Condition Transactions.

           

          (a)          In connection with any action being taken in connection with a Limited Condition Transaction, solely for purposes of determining compliance with any provision
            of this Indenture that requires that no Default or Event of Default, as applicable, has occurred, is continuing or would result from any such action, as applicable, such condition shall, at the option of the Company, be deemed satisfied, so
            long as no Default or Event of Default, as applicable, exists on the LCT Test Date.  For the avoidance of doubt, if the Company has exercised its option under the first sentence of this Section 4.08(a), and any Default or Event of Default
            occurs following the relevant LCT Test Date and prior to or on the date of the consummation of such Limited Condition Transaction, any such Default or Event of Default shall be deemed to not have occurred or be continuing for purposes of
            determining whether any action being taken in connection with such Limited Condition Transaction is permitted under this Indenture.

           

          (b)          In connection with any action being taken in connection with a Limited Condition Transaction, solely for the purposes of determining the amount or availability
            of any baskets set forth in this Indenture based on any metric (including baskets measured as a percentage of Consolidated Total Assets), at the option of the Company (the Company’s election to exercise such option in connection with any
            Limited Condition Transaction, an “LCT Election”), the date of determination of compliance with such provision or basket hereunder shall be deemed to be the date on which the definitive agreements or
            other documentation for such Limited Condition Transaction are entered into and/or delivered (the “LCT Test Date”), and if, after giving pro forma effect to the Limited Condition Transaction and the
            other transactions to be entered into in connection therewith as if they had occurred at the beginning of the four consecutive fiscal quarters most recently ended on or prior to the applicable LCT Test Date for which financial statements have
            been delivered or filed pursuant to Section 4.02, the Company could have taken such action on the relevant LCT Test Date in compliance with such provision or basket, such provision or basket shall be deemed to have been complied with. For the
            avoidance of doubt, if the Company has made an LCT Election and any of the baskets for which compliance was determined or tested as of the LCT Test Date are exceeded as a result of fluctuations in any such provision or basket, including due to
            fluctuations in Consolidated Total Assets of the Company or the Person subject to such Limited Condition Transaction, on or prior to the date of consummation of the relevant transaction or action, such baskets shall not be deemed to have been
            exceeded as a result of such fluctuations solely for purposes of determining whether such ratio or basket has been satisfied in connection with such Limited Condition Transaction.

           

          
            29

            
              


          

          (c)          If the Company has made an LCT Election for any Limited Condition Transaction, then (i) in connection with any subsequent calculation of any provision or
            basket on or following the relevant LCT Test Date and prior to the earlier of the date on which such Limited Condition Transaction is consummated or the definitive agreement or other documentation for such Limited Condition Transaction is
            terminated or expires without consummation of such Limited Condition Transaction, any such provision or basket shall be calculated on a pro forma basis assuming such Limited Condition Transaction and other transactions in connection therewith
            have been consummated and (ii) such provision or basket shall not be tested at the time of consummation of such Limited Condition Transaction.

           

          SECTION 4.09.  Further Instruments and Acts. The Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out
            more effectively the purpose of this Indenture.

          Successor Company

           

          SECTION 5.01.  When Company May













              Merge or Transfer Assets. (a) The Company shall not (i) amalgamate,
            consolidate with or merge into any other entity or (ii) convey, transfer or lease all or substantially all of the properties and assets of the Company and its Subsidiaries taken
            as a whole, unless: 

           

          (1)          the Company is the successor entity, or the successor or transferee entity, if other than the Company, is a Person
            organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and expressly assumes by a supplemental indenture executed and delivered to the Trustee, in form reasonably satisfactory to the
            Trustee, the due and punctual payment of the principal of, any premium on and any interest on all the outstanding Notes and the performance of every covenant and obligation in this Indenture to be performed or observed by the Company;

           

          (2)          immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, has
              happened and is continuing; and

           

          (3)          the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of
            Counsel, each in the form required by this Indenture and stating that such amalgamation, consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental
            indenture comply with this Section 5.01, and constitutes the legal, valid and binding obligation of the Company or successor entity, as applicable, subject to customary exceptions.

           

          (b)          In case of any such amalgamation, consolidation, merger, conveyance or transfer (but not lease), the successor entity shall
              succeed to and be substituted for the Company as obligor on the Notes, with the same effect as if it had been named in this Indenture as the Company. Notwithstanding Section 5.01(a), this Section 5.01 shall not apply to an amalgamation,
              merger, transfer or conveyance or other disposition of assets between or among the Company and the Guarantors.

          Defaults and Remedies

           

          SECTION 6.01.  Events of Default.
            Each of the following is an “Event of Default” with respect to the Notes: 

           

          (1)          a default in the payment of interest on any Note when the same becomes due and payable, and such default continues













            for a period of 30 consecutive days;

           

          (2)          (A) a default in the payment of the principal of any Note when the same becomes due and payable at its Stated Maturity, upon optional redemption, upon declaration of acceleration or otherwise, or (B)




            the failure by the Company to purchase Notes when required pursuant to this Indenture or the Notes;

           

          (3)          the failure by the Company to comply with Section 5.01;

           

          (4)          the failure by the Company or any direct or indirect parent
              company that provides a Guarantee of the Notes to comply with Section 4.02 and such failure continues for a period of 150 days after the notice specified in the second
            to last paragraph of this Section 6.01;

           

          (5)          the failure by the Company or any Guarantor to
            comply with any of its agreements contained in the Notes or this Indenture (other than those referred to in clause (1), (2), (3) or (4) above) and such failure continues for 60 days after the notice specified in the second to last paragraph of this Section 6.01;

           

          (6)          Debt of the Company,













              any Guarantor or any Significant Subsidiary is not paid within any applicable grace period after final
            maturity or is accelerated by the holders thereof because of a default, and the total amount of such Debt unpaid or accelerated exceeds $150.0 million, or its foreign
            currency equivalent at the time;

           

          (7)          the Company, any Guarantor or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Code:

           

          (A)          commences a voluntary case;

           

          (B)          consents to the entry of an order for relief against it in an involuntary case;

           

          (C)          consents to the appointment of a Custodian of it or for any substantial part of its property; or

           

          (D)          makes a general assignment for the benefit of its creditors;

           

          or takes any comparable action under any foreign laws relating to insolvency;

           

          
            31

            
              


          

          (8)          a court of competent jurisdiction enters an order or decree under any Bankruptcy Code that:

           

          (A)          is for relief against the Company, any Guarantor or any Significant Subsidiary in an involuntary case;

           

          (B)          appoints a Custodian of the Company, any Guarantor or any Significant Subsidiary or for any substantial part of its property; or

          or any similar relief is granted under any foreign laws; and, in each case under this clause (8), the order or decree remains unstayed and in effect for 60 days;

           

          (9)          any final judgment or decree for the payment of
            money (other than judgments which are covered by enforceable insurance policies) in excess of $250.0 million is entered against the Company, any Guarantor or any Significant Subsidiary, remains outstanding for a period of 60 consecutive days













            following such judgment becoming final and is not discharged, waived or stayed; or

           

          (10)        a Guarantee ceases to be in full force and effect
            (other than in accordance with the terms of such Guarantee) or a Guarantor denies or disaffirms its obligations under its Guarantee.

           

          The foregoing will constitute Events of Default whatever the reason for any such Event of Default













            and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order,
            rule or regulation of any administrative or governmental body.

           

          The term “Bankruptcy Code” means Title 11, United States Code, or any similar Federal or state law for the relief of
            debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Code.

           

          A Default under clauses (3), (4) or (5) does not constitute an Event of Default with respect to the Notes until the Trustee or the Holders of at least 30% in principal amount of the outstanding Notes notify the Company












              (with a copy to the Trustee if given by the Holders) of the Default and the Company does not cure such
            Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that
            it be remedied and state that such notice is a “Notice of Default.” In the event of any Event of Default specified under clause (6), such Event of Default and
            all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 30
            days after such Event of Default arose: (a) Holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (b) the default that is the basis for such Event of Default has
            been cured.

          SECTION 6.02.  Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(7) or (8) with respect to the Company) with respect
              to the Notes occurs and is continuing, the Trustee by written notice to the Company, or the Holders of at least 30% in principal amount of the outstanding Notes by written notice to the Company and the Trustee,
              may declare the principal of and accrued but unpaid interest, if any, and premium, if any, on all the Notes to be due and payable. Upon such declaration, such principal, interest and premium, if any, shall be due and payable immediately. If an Event of Default specified in Section 6.01(7) or (8) with respect to the Company occurs and is continuing, the principal of and interest (and premium,
                if any) on all the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any
              Noteholders. The Holders of a majority in principal amount of the outstanding Notes by written notice to the Trustee may rescind such acceleration and its consequences if the rescission
              would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

           

          SECTION 6.03.  Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

           

          The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Noteholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

           

          SECTION 6.04.  Waiver of Past Defaults. The Holders
            of a majority in principal amount of the Notes by written notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the principal of or interest on a Note, (b) a Default arising from the failure to redeem or purchase any Note when
            required pursuant to this Indenture or (c) a Default in












            respect of a provision that under Section 9.02 cannot be amended without the consent of each Noteholder affected. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. 

           

          SECTION 6.05.  Control by













              Majority. The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of other Noteholders (it being understood that the Trustee does not have an affirmative duty to ascertain
            whether or not any such directions are unduly prejudicial to such Noteholders) or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other
            action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it against all losses, liabilities and expenses caused by taking or not taking such action. 

           

          
            33

            
              


          

          SECTION 6.06.  Limitation on Suits. Except to enforce the
              right to receive payment of principal, premium (if any) or interest when due, no Noteholder may pursue any remedy with respect to this Indenture or the Notes unless: 

           

          (1)          the Holder delivers to the Trustee written notice stating that an Event of Default is continuing;

           

          (2)          the Holders of at least 30% in principal amount of the outstanding Notes make a written request to the Trustee
            to pursue the remedy;

           

          (3)          such Holder or Holders offer to and, if accepted, provide the Trustee security or indemnity





            satisfactory to the Trustee against any loss, liability or expense;

           

          (4)          the Trustee has not complied with such request
            within 60 days after receipt of the request and the Trustee has received an offer of and, if accepted, has been provided security or indemnity satisfactory to it; and

           

          (5)          the Holders of a majority in principal amount of the outstanding Notes have not given the Trustee a written
            direction inconsistent with the request within such 60-day period.

           

          A Noteholder may not use this Indenture to prejudice the rights of another Noteholder or to obtain a preference or priority over another Noteholder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Noteholders). In the event
            that the Definitive Notes are not issued to any beneficial owner promptly after the Registrar has received a
            request from the Holder of a Global Note to issue such Definitive Notes to such beneficial owner of its nominee,
            the Company expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy
            pursuant to this Indenture, the right of such beneficial holder of Notes to pursue such remedy with respect to the portion of the Global Note that represents such beneficial holder’s Notes as if such Definitive Notes had been issued.

           

          SECTION 6.07.  Rights of Holders













              to Receive Payment. Notwithstanding any other provision of this Indenture, the contractual right expressly set forth in this Indenture or the Notes of any Holder to receive payment of principal of and interest on the Notes held by such Holder, on or after the respective due dates
            expressed in the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be amended without the consent of such Holder. 

           

          SECTION 6.08.  Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its
            own name and as trustee of an express trust against the Company for the whole amount then due and owing
            (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07. 

           

          
            34

            
              


          

          SECTION 6.09.  Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Noteholders allowed in any
              judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent in writing to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. 

           

          SECTION 6.10.  Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order: 

           

          FIRST: to the Trustee for amounts due under Section 7.07;

           

          SECOND: to Noteholders for amounts due and unpaid on the Notes for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest, respectively; and

           

          THIRD: to the Company.

           

          The Trustee may fix a record date and payment date for any payment to Noteholders pursuant to this
            Section. At least 15 days before such record date, the Company shall mail to each Noteholder and the Trustee a notice that states the record date, the payment date and amount to be paid.

           

          SECTION 6.11.  Undertaking for Costs. 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, a court in its discretion may require the filing by any party litigant (other than the Trustee) in the suit of an undertaking to pay the costs of the
            suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to
            the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the Notes. 

           

          SECTION 6.12.  Waiver of Stay or













              Extension Laws. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or












            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, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such
            law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall
            suffer and permit the execution of every such power as though no such law had been enacted.

          ARTICLE 7

               

          

          Trustee

           

          SECTION 7.01.  Duties of Trustee
            . 

           

          (a)          The Trustee, prior to the occurrence of an Event of Default with respect to the Notes and after the curing or waiving of all Events of
            Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. If an Event of Default has occurred and
            is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same
            degree of care and skill in its exercise of those rights and powers as a prudent Person would exercise or use
            under the circumstances in the conduct of such Person’s own affairs.

           

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

           

          (1)          the Trustee undertakes to perform such duties and only such duties as are
            specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee (it being agreed that the
              permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty); and

           

          (2)          in the absence of bad faith on its part, 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 conforming to the requirements of this Indenture. The Trustee shall be under no duty to make any investigation as to any
            statement contained in any such instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. However, in the case of certificates or opinions required by any provision
            hereof to be provided to it, the Trustee shall examine the form of certificates and opinions to determine whether or not




            they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of
            mathematical calculations or other facts stated therein).

           

          (c)          The Trustee may not be relieved from liability for its own negligent
            action, its own negligent failure to act or its own willful misconduct, except that:

           

          (1)          this paragraph (c) does not limit the effect of paragraph (b) of this
            Section 7.01;

           

          (2)          the Trustee shall not be liable for any error of judgment made in good
            faith by a Responsible Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent
            facts;

           

          (3)          the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05; and

           

          
            36

            
              


          

          (4)          no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the
            performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or indemnity satisfactory to it against such risk or liability is not
            reasonably assured to it.

           

          (d)          Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

           

          (e)          The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.

           

          (f)          Money held in trust by the Trustee need not be segregated from other
            funds except to the extent required by law.

           

          (g)          The Trustee may refuse to perform any duty or exercise any right or power or extend or risk its own funds or otherwise incur any financial liability unless
            it receives indemnity satisfactory to it against any loss, liability or expense which might be incurred by it.

           

          (h)          Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01.

           

          SECTION 7.02.  Rights of Trustee.
          

           

          (a)          The Trustee may conclusively rely upon and shall be protected in acting or refraining from acting upon any resolution, certificate,
            statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper
            person or persons, not only as to due execution, validity and effectiveness, but also as to the truth and accuracy of any information contained therein. The Trustee need not investigate any fact or matter stated in the document.

           

          (b)          Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officer’s Certificate or Opinion of Counsel.

           

          (c)          The Trustee may act directly or indirectly through agents or attorneys and shall not be responsible for the misconduct or negligence













            of any agent or attorney appointed with due care.

           

          (d)          The Trustee shall not be responsible or liable for any action it takes
            or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence.

           

          (e)          The Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and













            the Notes shall be full and complete authorization and protection from liability in respect of any action taken, omitted or













            suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

           

          
            37

            
              


          

          (f)          Any request or direction of the Company













            mentioned herein shall be sufficiently evidenced by a written request or direction from the Company or a Company Order, and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution.

           

          (g)          The Trustee shall be under no obligation to exercise any of the rights
            or powers vested in it by this Indenture at the request or





            direction of any of the Holders pursuant to this Indenture, unless such Holders shall





            have offered and, if accepted, provided to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

           

          (h)          The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
            instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document unless requested in writing to do so by the Holders of not less than a majority in principal amount of the Notes at the
            time outstanding and indemnified in accordance with Section 6.05, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine (or is
            requested in writing by the Holders as set forth above) to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, at the expense of the
            Company and shall incur no liability of any kind by reason of such inquiry or investigation.

           

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

           

          (j)          The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at




            the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

           

          (k)          The rights, privileges, protections, immunities and benefits given to the Trustee,
            including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in













            each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder;

           

          (l)          The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified
            actions pursuant to this Indenture;

           

          
            38

            
              


          

          (m)          Neither the Trustee in its individual capacity, nor any of its owners, beneficiaries, agents,
            officers, directors, employees, affiliates, successors or assigns will, in the absence of an express agreement to the contrary, be personally liable for the payment of any
            amounts required to be paid under the Notes or for the agreements of the Company contained herein.

           

          (n)          The Trustee shall not be responsible or liable for any action taken or omitted by it in good faith at the direction of the Holders
            of not less than a majority in principal amount of the Notes in accordance with Section 6.05 as to the time, method and place of conducting any proceedings for any remedy available to the Trustee or the exercising of any power conferred by this
            Indenture.

           

          (o)          Any action taken, or omitted to be taken, by the Trustee in good faith pursuant to this Indenture upon the request or authority or
            consent of any person who, at the time of making such request or giving such authority or consent, is the Holder of any Note shall be conclusive and binding upon future Holders of Notes and upon Notes executed and delivered in exchange therefor
            or in place thereof.

           

          (p)          The Trustee shall not be required to give any bond or surety in respect of the execution of the trusts and powers under this Indenture

           

          SECTION 7.03.  Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company













            or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Section 7.10. 

           

          SECTION 7.04.  Trustee’s













              Disclaimer. The recitals contained herein and in the Notes, except the Trustee’s certificates of
            authentication, shall be taken as the statements of the Company, and the Trustee or any Authenticating Agent assumes no responsibility for their correctness. The Trustee shall not be responsible for and makes no
            representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use or application of the proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the
            sale of the Notes or in the Notes other than
            the Trustee’s certificate of authentication or the determination as to which beneficial owners are entitled to
            receive any notices hereunder.  In accepting the trust hereby created, the Trustee acts solely as Trustee under this Indenture and not in its individual capacity, and all persons, including without limitation the Holders of Notes and the
            Company, having any claim against the Trustee arising from this Indenture shall look only to the funds and accounts held by the Trustee hereunder for payment except as otherwise provided herein. 

           

          SECTION 7.05.  Notice of Defaults. If a Default with respect to the Notes occurs, is continuing and is actually known to the Trustee, the Trustee shall mail (or deliver by electronic transmission in accordance with the Applicable Procedures of DTC) to each Noteholder notice of the Default within 90 days after it occurs. Except in the case of a Default in




            the payment of principal of, interest or premium on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is not
            opposed to the interest of the Noteholders. 

           

          
            39

            
              


          

          SECTION 7.06.  Reports by Trustee to Holders. Within 60 days after each January 15 beginning with the January 15 following the date of this Indenture, and in any event prior to January 15 in each year, the Trustee shall mail to each Noteholder a brief report dated as of such January 15. 

           

          If the Notes are listed on any stock exchange, a copy of each report at the time of its mailing to Noteholders shall be filed with the SEC and such stock exchange. The Company agrees to promptly notify the Trustee in













            writing whenever the Notes become listed on any stock exchange and of any delisting thereof.

           

          SECTION 7.07.  Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its services as the Company and the Trustee shall from time to time agree in writing. The Trustee’s
            compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall
            reimburse the Trustee upon request for all expenses, disbursements and advances incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of
            the Trustee’s agents, counsel, accountants and experts. 

           

          The Company agrees to indemnify and hold harmless the Trustee, the respective
            affiliates of the Trustee, any predecessor Trustee, and the respective officers, directors, employees, agents (including, without limitation each of their counsel), and controlling persons of the Trustee, and each such affiliate (each, an “Indemnified Party”) from and against any and all claims, actions and suits
            whether groundless or otherwise, and from and against any and all liabilities, losses, damages and costs and expenses (including,
            without limitation, the reasonable fees and disbursements of counsel and with respect to the Trustee, reasonably allocated costs and expenses of in-house counsel and legal staff)
            of every nature and character arising out of or in connection with any actual or threatened claim, litigation,
            investigation or proceeding relating to this Indenture or the transactions contemplated hereby (other than any
            such actions or expenses resulting, as determined by a final order of a court of competent jurisdiction, from the negligence or willful misconduct of the Indemnified Party seeking indemnification hereunder), in each case including,
            without limitation, the reasonable fees and disbursements of counsel and allocated costs of in-house counsel and legal staff incurred in connection with any such claim investigation, litigation or other proceeding whether or not such Indemnified Party is a party thereto, and the Company agrees to reimburse each Indemnified Party, upon demand, for all out-of-pocket costs and expenses (including, without limitation, the reasonable fees and disbursements of counsel and with respect to the Trustee,
            reasonably allocated costs and expenses of in-house counsel and legal staff) incurred in connection with any of the foregoing.  In litigation, or the preparation therefor, the Indemnified Parties shall each be entitled to select their own counsel and, in addition to the foregoing indemnity, the Company












            agrees to pay promptly the reasonable fees and expenses of such counsel.  If, and to the extent that the obligations of the Company under this Section 7.07 are unenforceable for any reason, the Company hereby
            agrees to make the maximum contribution to the payment in satisfaction of such obligations which is permissible under applicable law.

           

          
            40

            
              


          

          The Company shall not make any claim against any Indemnified Party for any
            special, indirect, punitive or consequential damages in respect of any breach or wrongful conduct (whether the
            claim therefor is based in contract, tort or duty imposed by law) in connection herewith, arising out of or in
            any way related to the transactions contemplated hereby, or any act, omission or event occurring in connection
            herewith, and hereby waives, releases and agrees not to sue upon any such claim for any such damages, whether or not accrued and whether or not known or suspected to exist in the Company’s favor.

           

          The covenants contained in this Section 7.07 shall survive payment or satisfaction
            in full of all other of the obligations under this Indenture.

           

          To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien on all money or property





            held or collected by the Trustee other than money or property













            held in trust to pay principal of and interest on particular Notes.

           

          The Company’s payment obligations pursuant to this Section shall survive the
            discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in
            Section 6.01(7) or (8) with respect to the Company, the expenses, including the reasonable charges and expenses of its counsel, are intended to constitute
            expenses of administration under the Bankruptcy Code.

           

          SECTION 7.08.  Replacement of Trustee.
            The Trustee may resign at any time by so notifying the Company, the Paying Agent and the Holders. The Holders of a majority in principal amount












            of the Notes at the time outstanding may remove the Trustee by so notifying the Trustee and the Company in writing and may appoint a successor Trustee.
            The Company shall remove the Trustee if: 

           

          (1)          the Trustee fails to comply with Section 7.10;

           

          (2)          the Trustee is adjudged bankrupt or insolvent;

           

          (3)          a receiver or other public officer takes charge
            of the Trustee or its property; or

           

          (4)          the Trustee otherwise becomes incapable of acting.

           

          No resignation or removal of the Trustee shall be effective until a successor Trustee has been appointed. The Company may appoint a temporary trustee until the appointment of such successor Trustee. If the Trustee resigns, is removed by
            the Company or by the Holders of a majority in principal amount of the Notes and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee
            for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

           

          A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee













            and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of
            its succession to Noteholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee upon the repayment of all the retiring Trustee’s













            fees and expenses then due and payable and subject to the lien provided for in Section 7.07.

           

          
            41

            
              


          

          If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee,
            at the Company’s expense, or the Holders of 10% in principal amount of the Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

           

          If the Trustee fails to comply with Section 7.10, any Noteholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

           

          Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s













            obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

           

          SECTION 7.09.  Successor Trustee













              by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets













            to, another corporation or banking association, the resulting, surviving or transferee corporation without any
            further act shall be the successor Trustee. 

           

          In case, at the time such successor or successors by merger, conversion or consolidation
















            to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any
            predecessor trustee and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have.

           

          SECTION 7.10.  Eligibility; Disqualification; Preferential Collection of Claims Against the
              Company. (a) The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.  This
            Indenture shall always have a Trustee who satisfies the requirements of Trust Indenture Act Sections 310(a)(1), (2) and (5). The Trustee is subject to Trust Indenture Act Section 310(b). 

           

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

           

          SECTION 7.11.  Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company












            may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the
            Trustee under this Indenture and the date on and/or after












            which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any
            action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the
            date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an
            omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted. 

           

          
            42

          Discharge of Indenture; Defeasance

           

          SECTION 8.01.  Discharge of Liability on Notes; Defeasance. 

           

          (a)          Subject to Section 8.01(c), this Indenture shall be discharged, and will cease to be of further effect as to all Notes issued thereunder,
            when either:

           

          (1)          all Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for
            whose payment money has been deposited in trust) have been delivered to the Trustee for cancellation; or

           

          (2)          (A) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the giving of a notice of
            redemption or otherwise, will become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the
            expense, of the Company, and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee, as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, Government Securities, or a
            combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm
            delivered to the Trustee if Government Securities are delivered, without consideration of any reinvestment of interest, to pay and discharge the entire Debt on the Notes not theretofore delivered to the Trustee for cancellation for principal,
            premium, if any, and accrued interest to the date of maturity or redemption, as the case may be;

           

          (B)          no Default or Event of Default with respect to the outstanding Notes has occurred and is continuing on the date of such deposit or will
            occur as a result of such deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Debt and, in each case, the
            granting of Liens in connection therewith);

           

          (C)          the Company or any Guarantor has paid or caused to be paid all other sums payable by the Company under this Indenture; and

           

          (D)          the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity
            or the redemption date, as the case may be.

           

          
            43

            
              


          

          In addition, the Company shall deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all
            conditions precedent to satisfaction and discharge have been satisfied.  The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officer’s Certificate and an Opinion of Counsel and at the cost and
            expense of the Company.

           

          (b)          Subject to Sections 8.01(c) and 8.02, the Company may, at its option and at any time, elect to discharge (1) all of its obligations under the Notes and this Indenture and any Guarantees issued hereunder with respect to the Notes (“legal defeasance option”) or (2) its obligations set forth in Sections 4.02,
              4.03, 4.04, 4.05, 4.07 and 5.01(2) and the operation of Sections 6.01(4), 6.01(5), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and 6.01(10) (but, in the case of Section 6.01(7) and (8), with respect only to Significant Subsidiaries) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

           

          If the Company exercises its legal defeasance option, (i) payment of the Notes may not be accelerated because of an Event of Default with respect to the Notes and (ii) the Guarantees in effect at such time of exercise will be automatically released.  If the Company exercises












            its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in Sections 6.01(3) (with respect to
            Section 5.01(2) only), 6.01(4), 6.01(5), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and 6.01(10) (but, in the case of Sections 6.01(7) and (8), with respect only to Significant Subsidiaries).

           

          Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee













            shall acknowledge in writing the discharge of those obligations that the Company terminates.

           

          (c)          Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07 and 7.08 and in this Article 8 shall survive until the Notes have been paid in full. Thereafter, the Company’s obligations in
            Sections 7.07 and 8.05 shall survive.

           

          SECTION 8.02.  Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if: 

           

          (1)          the Company irrevocably deposits with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in amounts as will be sufficient, in the opinion of













            a nationally recognized firm of independent public accountants, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm delivered to the Trustee, without consideration of any reinvestment of interest, to
            pay the principal, premium, if any, and interest due on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company shall specify whether the Notes are being defeased to maturity or to
            a particular redemption date;

           

          
            44

            
              


          

          (2)          in the case of the legal defeasance option, the Company has delivered to the Trustee an Opinion of Counsel confirming that, subject to
            customary assumptions and exclusions, (a) the Company has received from, or there has been published by, the U.S. Internal Revenue Service a ruling, or (b) since the Issue Date, there has been a change in the applicable U.S. federal income tax
            law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that the beneficial owners of the Notes will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as
            would have been the case if such legal defeasance had not occurred;

           

          (3)          in the case of the covenant defeasance option, the Company has delivered to the Trustee an Opinion of Counsel
            confirming that, subject to customary assumptions and exclusions, the beneficial owners of the Notes will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such
            covenant defeasance had not occurred;

           

          (4)          no Default or Event of Default with respect to the outstanding Notes has occurred and is continuing on the date of
            such deposit or will occur as a result of such deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Debt and, in
            each case, the granting of Liens in connection therewith), and the deposit will not result in a breach or violation of, or constitute a default under, the Credit Agreement;

           

          (5)          the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel
            may be subject to customary assumptions and exclusions), each stating that all conditions precedent relating to the legal defeasance or the covenant defeasance, as the case may be, have been complied with; and

           

          (6)          the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of
            the Notes at maturity or the redemption date, as the case may be.

           

          Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Notes at a future date in accordance with Article 3.

           

          SECTION 8.03.  Application of Trust Money. Subject to Section 8.04, the Trustee shall hold in trust money or Government Securities (including proceeds thereof) deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from Government Securities through the Paying





              Agent and in accordance with this Indenture to the payment of principal of and interest on the Notes. 

           

          SECTION 8.04.  Repayment to Company.
            Each of the Trustee and the Paying Agent shall pay to the Company upon written request any excess money, Government Securities or securities held by them at
            any time. 

           

          Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall













            pay to the Company upon written request any money held by them for the payment of principal or interest with respect to the Notes that remains unclaimed for two
            years, and, thereafter, Noteholders entitled to the money must look to the Company for payment as general creditors, unless an
            applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Holders with respect to such money for that period commencing after the return thereof.

           

          
            45

            
              


          

          SECTION 8.05.  Indemnity for Government Securities. The Company
            shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited Government Securities or the




            principal and interest received on such Government Securities, except with respect to any such tax, fee or other charge which by law is for the account of the Noteholders; provided, however, it is understood and agreed that the Trustee shall not be responsible for any such tax, fee or other charge. 

           

          SECTION 8.06.  Reinstatement. If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with this Article 8 by reason of any legal
            proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s












            obligations under this Indenture, and the Notes so





            discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until












            such time as the Trustee or Paying Agent is
            permitted to apply all such money or Government Securities in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations,
            the Company shall be subrogated to the rights of the Holders of such Notes to












            receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

          Amendments

           

          SECTION 9.01.  Without Consent of Holders. The Company, any Guarantor and the Trustee may amend or supplement this Indenture, the Notes or the Guarantees without notice to or consent of

            46

            
              


          

          (6)          to make any change that does not materially adversely affect the rights of any Noteholder, as determined
              in good faith by the Company;

          After an amendment under this Section 9.01 becomes effective, the Company shall mail (or deliver by electronic transmission in accordance with the

The Company, the Guarantors and the Trustee may amend this Indenture, the Notes or the Guarantees with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the
            Notes) and any past default or compliance with any provisions may also be waived with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including
            consents obtained in connection with a tender offer or exchange offer for the Notes). However, without the consent of each Noteholder affected thereby, an amendment or waiver may not, among other things: 

           

          (1)          reduce the amount of Notes whose Holders must consent to an amendment;

           

          (2)          reduce the rate of or extend the time for payment of
            interest on any Note;

           

          (3)          reduce the principal of or extend the Stated Maturity of any Note;

           

          
            47

            
              


          

          (4)          change the optional redemption dates or prices or calculations from those described in Article 3 hereto or paragraph 6 of the Notes;

           

          (5)          make any Note payable in money other than that
            stated in the Note;

           

          (6)          amend the contractual right expressly set forth in this Indenture or the Notes of any Holder of
            the Notes to receive payment of principal of and interest












            on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes;

           

          (7)          make any change in Section 6.04 or 6.07 or this second sentence of this Section 9.02;

           

          (8)          make any change in the ranking or priority of any Note or Guarantee that would adversely affect the Noteholders; or

           

          (9)          release any Guarantor













            from its Guarantee, except as provided for in this Indenture.

           

          It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

           

          After an amendment under this Section 9.02 becomes effective, the Company shall mail (or deliver by electronic transmission in accordance with the Applicable Procedures
            of DTC) to Noteholders a notice briefly describing such amendment. However, the failure to give such notice to Noteholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

           

          SECTION 9.03.  Revocation and Effect of Consents and Waivers. A consent to an amendment
            or a waiver by a Holder of a Note shall bind
            the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note.
            However, any such Holder or subsequent Holder may




            revoke the consent or waiver as to such Holder’s Note or




            portion of the Note if the Trustee receives the written notice of revocation before the date the
            amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Noteholder. An amendment or waiver becomes effective upon (i) receipt by
            the Company or the Trustee of consents by the Holders of the requisite principal amount of securities, (ii) satisfaction





            of conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing
            such amendment or waiver and (iii) the execution of such amendment or waiver by the Trustee. 

           

          The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Noteholders
            entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph,
            those Persons who were Noteholders at such record date (or their duly
            designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent
            previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more
            than 120 days after such record date.

           

          
            48

            
              


          

          SECTION 9.04.  Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note,
            the Trustee or the Company may require the Holder of the Note to deliver it to the Trustee.
            The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note





            shall issue and the Trustee, upon receipt of a Company Order, shall authenticate a new Note that reflects
            the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity
            of such amendment. 

           

          SECTION 9.05.  Trustee To Sign Amendments. The Trustee shall sign any amendment, supplement or waiver to this Indenture authorized





            pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall




            be entitled to receive indemnity reasonably satisfactory to it and shall be provided with, and (subject to Section 7.01) shall be fully protected in relying upon, (i) an Officer’s Certificate and (ii) an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by or complies with this Indenture. 

           

          ARTICLE 10

            

            Guarantee

           

          SECTION 10.01.  Guarantee. 

           

          (a)          Subject to this Article 10, each of the Guarantors shall, jointly and severally, unconditionally guarantee to each Holder
            of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

           

          (1)          the principal of, premium and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the
            Company to the Holders or the Trustee hereunder
            or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof;
            and

           

          (2)          in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same
            will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal,
            whether at Stated Maturity, by acceleration or otherwise.

           

          Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

           

          
            49

            
              


          

          (b)          The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with
            respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to
            enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby
            waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

           

          (c)          If any Holder or





            the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the
            Company or the Guarantors, any amount paid by
            either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

           

          (d)          Each Guarantor agrees that it will not be entitled to any right of
            subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors,
            on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due
            and payable) will forthwith become due and payable by the Guarantors for the purpose of this Guarantee.
            The Guarantors will have the right to seek contribution from any non-paying Guarantor, so long as the exercise
            of such right does not impair the rights of the Holders under this Guarantee, in an amount equal to such other
              Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

           

          SECTION 10.02.  Limitation on Guarantor













              Liability. Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that this Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy













              Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will












            be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent
            and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any
            collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor




            under this Article 10, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance.




          

           

          
            50

            
              


          

          

          SECTION 10.03.  Delivery of Guarantee.The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Guarantee set forth in this Indenture or any supplemental indenture on behalf of the Guarantors. Neither the Company nor any Guarantor shall be required to make a notation on the Notes to











            reflect any Guarantee or any such release, termination or discharge thereof. 

           

          SECTION 10.04.  Guarantors May Consolidate, etc., on Certain
              Terms.Except as otherwise provided in Section 10.05 hereof, no Person that becomes a Guarantor may at any
            time on or after the date hereof sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the
            surviving Person) another Person, other than the Company
            or another Guarantor, unless immediately












            after giving effect to such transaction, no Default or Event of Default exists. 

           

          Except as set forth in Articles 4 and 5 hereof, and notwithstanding this Section 10.04, nothing contained in this Indenture or in any of the Notes will prevent any
            consolidation or merger of a Guarantor with or into













            the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

           

          The Trustee, subject to the provisions of Section 11.03 hereof, will receive an Officer’s
              Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale or conveyance,













            and any such assumption of obligations, comply with the provisions of this Section 10.04 hereof. Such certificate and opinion will comply with the provisions of Section 11.04.

           

          SECTION 10.05.  Releases

           

          (a)          The Guarantee of a Guarantor shall be automatically released, and such Guarantor shall be relieved of any obligations under its
            Guarantee:

           

          (1)          in the event of any sale or other disposition (including by way of amalgamation, consolidation or merger) of a Guarantor or in the event of a sale or disposition of all or substantially all of the assets of a Guarantor, in each case to a Person that




            is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company;

           

          (2)          if the legal defeasance option is exercised or this Indenture is otherwise discharged in accordance with Article 8 hereof;

            Agreement, except a discharge or release by or as a result of payment in connection with the enforcement of remedies under such guarantee or direct obligation; or

          Upon delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that the conditions to the release of such Guarantee have been met in
            accordance with this Indenture, the Trustee will execute any documents reasonably required in order to evidence
            the release of any Guarantor from its obligations under its Guarantee.

           

          (b)          Any Guarantor not released from its obligations under its Guarantee as provided in this Section 10.05 will remain liable for the
            full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

           

          SECTION 10.06.  Addition of Guarantors.

           

          If the Company is required to cause a Subsidiary to become a Guarantor pursuant to Section 4.07, the Company shall cause such Subsidiary to (1) execute and deliver to the Trustee a supplemental indenture
            substantially in the form of Annex 1 hereto pursuant to which such Subsidiary shall unconditionally Guarantee all of the Company’s obligations under the Notes on the terms set forth in this Indenture and (2) deliver, in the time period required
            by Section 4.07, to the Trustee an Opinion of Counsel reasonably satisfactory to the Trustee that such supplemental indenture has been duly executed and delivered by such Subsidiary.

            by notice to the other may designate additional or different addresses for subsequent notices or communications.

           

          Any notice or communication mailed to a Noteholder shall be mailed to the Noteholder at the Noteholder’s address as it appears on the registration books of the Registrar and shall be
            sufficiently given if so mailed within the time prescribed. Notwithstanding any other provision of this Indenture or any Note, where this Indenture or any Note provides for notice of any event (including any notice of redemption or purchase) to
            a Holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to DTC (or its designee) pursuant to the standing instructions from DTC or its designee.

            elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be
            deemed controlling.  The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding if such instructions conflict or are
            inconsistent with a subsequent written instruction.  The party providing electronic instructions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including
            without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

           

          Failure to mail a notice or communication to a Noteholder or any defect in it
            shall not affect its sufficiency with respect to other Noteholders.

            reasonably satisfactory to the Trustee stating that, in the opinion of the signer, all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with; and

           

          (2)          an Opinion of Counsel in form and substance
            reasonably satisfactory to the Trustee stating that, in the opinion of such counsel, all such conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with.

           

          SECTION 11.04.  Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture shall include: 

           

          (1)          a statement that the individual making such certificate or opinion













            has read such covenant or condition;

            are based;

           

          (3)          a statement that, in the opinion of such individual, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with; and

           

          (4)          a statement as to whether or not, in the opinion of
            such individual, such covenant or condition has been complied with; provided, however, that with respect to matters of fact, an Opinion of Counsel may rely on an Officer’s













              Certificate or certificates of public officials.

           

          SECTION 11.05.  When Notes Disregarded. In determining whether the Holders of the required principal amount of Notes have concurred in any direction,
            waiver or consent, Notes owned by the Company or by any Person directly or indirectly
            controlling or controlled by or under direct or indirect












            common control with the Company shall be disregarded and deemed not to be outstanding, except that, for the
            purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent,





            only Notes which a Responsible Officer of the Trustee
            actually knows are so owned shall be so disregarded. Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination. 

           

          SECTION 11.06.  Rules by Trustee,
            Paying Agent and Registrar. The Trustee may make reasonable rules for action by or a meeting of Noteholders. The Registrar and the Paying Agent may make reasonable rules for their functions.

          SECTION 11.07.  Legal Holidays. If a payment date or redemption date is not a Business Day, payment shall be made on the next succeeding day that is a Business Day,

            who the transferor reasonably believes to be a QIB, (b) purchasing for its own account or the




            account of a QIB in a transaction meeting the requirements of Rule 144A, and (c) in accordance with all
            applicable securities laws of the States of the United States and other jurisdictions.

           

          Beneficial interests in Regulation S Global Notes (after the Distribution Compliance Period) and Rule 144A Global Notes may be exchanged for an interest in IAI Global Notes if (1) such exchange occurs in connection with a transfer of the securities in compliance with an exemption
            under the Securities Act and (2) the transferor of the Regulation S Global Note or Rule 144A Global Note, as applicable, first delivers to the Trustee a written certificate (substantially in the form of Exhibit 2 hereto) to the effect that (A) the Regulation S Global Note or Rule 144A Global Note, as applicable, is being transferred (a) to
            an “accredited investor” within the meaning of 501(a)(1), (2), (3) and (7) under the Securities Act that is an
            institutional investor acquiring the securities for its own account or for the account of such an institutional




              accredited investor, in each case in a minimum principal amount of the securities of $250,000, for investment purposes and not with a view to or for offer or sale in connection with any distribution in violation of the Securities Act and (B) in accordance with all applicable securities laws of
            the States of the United States and other jurisdictions.

            whether before or after the expiration of the Distribution Compliance Period, only if the transferor first
            delivers to the Trustee a written certificate to the effect that such transfer is being made in accordance with Rule 903 or




            904 of Regulation S or Rule 144 (as applicable) and that, if such transfer occurs prior to the expiration
            of the Distribution Compliance Period, the interest transferred will be held immediately thereafter through

              to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

           

          (A)   if such Definitive Notes are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a written certification from such Holder to that effect; or

           

          (B)   if such Definitive Notes are being transferred to the Company, a written certification to that effect; or

            a Rule 144A Global Note, an IAI Global Note or a Regulation S Permanent Global Note except
            upon satisfaction of the requirements set forth below; provided that in no event shall Definitive Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S Temporary

            6

          

          (i)   certification, in the form set forth on the reverse of the Note, that such Definitive Note is either (A) being transferred to a QIB in accordance with Rule 144A, (B) being transferred to an IAI or (C) being transferred after expiration of the Distribution Compliance Period by a Person who initially purchased such Note in





              reliance on Regulation S to a buyer who elects to hold its interest in such Note in the form of a beneficial interest in the Regulation S Permanent Global
              Note; and

           

          (ii)   written instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its books
              and records with respect to such Rule 144A Global Note (in the case of a transfer pursuant to clause (b)(i)(A)), IAI Global Note (in the case of a transfer pursuant to clause (b)(1)(B)) or Regulation S Permanent Global Note (in the case of a transfer pursuant
              to clause (b)(i)(C)) to reflect an increase in the aggregate principal amount of the Notes represented by the Rule 144A Global Note, IAI Global Note or Regulation S Permanent Global Note, as applicable, such instructions to contain information regarding the Depository account to be credited
              with such increase,

              144A Global Note, IAI Global Note or Regulation S Permanent Global Note, as applicable, equal to the principal amount












            of the Definitive Note so canceled. If no Rule 144A Global Notes, IAI Global Notes or Regulation S Permanent Global Notes, as applicable, are then
            outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officer’s Certificate of
            the Company, a new Rule 144A Global Note, IAI Global
              Note or Regulation S Permanent Global Note,
            as applicable, in the appropriate principal amount.

            exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with this Indenture (including applicable
            restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor; provided, however, that prior to the expiration of the Distribution Compliance Period, transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a U.S.
            Person (other than an Initial Purchaser). A transferor of a beneficial interest in a Global Note shall deliver to the Registrar













            a written order given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Note. The Registrar












            shall, in accordance with such instructions instruct the Depository to credit to the account of the Person specified












            in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the
            transfer the beneficial interest in the Global Note being transferred.

          (ii)   If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest




              to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred.

           

          (iii)   Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by
              a nominee of the Depository to the Depository or another













              nominee of the Depository or by the Depository or any such nominee to a successor Depository or a
              nominee of such successor Depository.

           

          (iv)   In the event that a Global Note is exchanged for Definitive Notes pursuant to Section 2.4 of this Appendix, such Notes may





              be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Notes intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

            interests in Regulation S Temporary Global Notes may only be sold, pledged or transferred in accordance with the Applicable Procedures and only (i) to the Company, (ii) in an offshore transaction in accordance with Regulation S (other than a

            State of the United States.  Further, a beneficial interest in the Regulation S Temporary Global Note may not be exchanged for a Definitive Note or transferred to a Person who takes delivery thereof in the form of a Definitive Note prior to (A)
            the expiration of the Distribution Compliance Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act, except in the case of a transfer pursuant to an exemption from
            the registration requirements of the Securities Act other than Rule 903 or Rule 904.

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

          [FORM OF REVERSE SIDE OF NOTE]

            2.800 % Senior Note due 2030

           

          1.           Interest

           

              

          CoStar Group, Inc., a Delaware corporation (such corporation and its successors and assigns under the Indenture hereinafter referred to, being
            herein called the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Company will












            pay interest semiannually on January 15 and July 15 of each year, commencing January 15, 2021. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from July 1, 2020. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this Note, and it will pay interest on overdue installments of interest at the same rate to the extent lawful.

           

          2.           Maturity

           

          The Notes will mature on July 15, 2030.

           

          3.           Method of Payment

           

          

          The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the January 1 and July 1 next preceding the interest












            payment date even if Notes are canceled after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to
            collect principal payments. The Company will pay principal












            and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a Global Note (including principal,
            premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Note (including principal, premium and interest) at the office of the Paying




              Agent, except that, at the option of the Company, payment of interest may be made by mailing a check to
            the registered address of each Holder thereof; provided, however, that
            payments on a certificated Note will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due
            date for payment (or such other date as the Trustee may accept in its discretion).

           

          4.           Paying Agent and Registrar

           

              

           Initially, Wilmington Trust, National Association, a national banking association (the “Trustee”), will act as Paying Agent and Registrar and DTC custodian. The Company may appoint and change any
            Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

           

          
            
              


            6

          

          5.           Indenture

           

          

          The Company issued the Notes under an Indenture dated as of July 1, 2020 (the “Indenture”), among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. Terms defined in the Indenture and not defined herein have the
            meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Noteholders are referred to the Indenture for a statement of those terms.

           

          The Notes are general unsecured senior obligations of the Company. The Company shall be entitled to issue Additional Notes pursuant to Section 2.12 of the Indenture. The Notes issued on the Issue Date and any Additional Notes
            will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants
            that limit the ability of the Company and its subsidiaries to create certain liens on assets; consolidate, merge or transfer




            all or substantially all of its assets and the assets of its subsidiaries; and enter into sale/leaseback transactions. These covenants are subject to important exceptions and
            qualifications.

           

          6.           Optional Redemption

           

          

          At any time prior to April 15, 2030 (three months before the maturity date of the Notes) (the “Par Call Date”), the Company may, at its option, redeem some or all of the
            Notes at any time and from time to time upon notice pursuant to Section 3.02 of the Indenture at a redemption price (the “Make-Whole Redemption Price”) equal to 100% of the principal amount of the Notes
            plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but excluding, the redemption date.

           

          The Make-Whole Redemption Price will be calculated assuming a 360-day year consisting of twelve 30-day months.  For purposes of
            calculating the Make-Whole Redemption Price, the following terms will have the meanings set forth below:

           

          “Adjusted Treasury Rate”  means, with respect to a Note at any redemption date, subject to a 0% floor, (1) the yield, under the heading which represents the average for the
            immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes
            yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months
            before or after the Par Call Date, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on
            a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual
            equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in each case calculated on the third Business Day immediately
            preceding the date that the applicable redemption notice is first mailed or sent, in the case of each of clauses (1) and (2), plus 35 basis points.

           

          
            
              


            7

          

          “Applicable Premium” means, with respect to a Note at any redemption date, as provided by the Company, the excess of (1) the present value at such redemption date of the
            Remaining Scheduled Payments on such Note (but excluding accrued and unpaid interest, if any, to, but excluding, the redemption date), computed using a discount rate equal to the Adjusted Treasury Rate, over (2) the principal amount of such
            Note on such redemption date.

           

          “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having
            a maturity comparable to the remaining term of the Notes from the redemption date to the Par Call Date, that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate
            debt securities of a maturity most nearly equal to the Par Call Date.

           

          “Comparable Treasury Price” means, with respect to a Note at any redemption date, if clause (2) of the Adjusted
            Treasury Rate definition is applicable,

           

          (1)          the average of the Reference Treasury Dealer Quotations for that redemption date, after
            excluding the highest and lowest of the Reference Treasury Dealer Quotations;

           

          (2)          if the Company obtains fewer than four Reference Treasury
              Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received; or

           

          (3)          if only one Reference Treasury Dealer Quotation is received, such quotation.

           

          “Quotation Agent” means one of the Reference Treasury Dealers selected by the Company.

           

          “Reference Treasury Dealer” means each of four primary U.S. Government securities dealers in New York City (each a “Primary Treasury Dealer”), consisting of (i) J.P. Morgan Securities LLC (or its affiliate), (ii) Citigroup Global Markets Inc. (or its affiliate) and (iii) two other nationally recognized investment
            banking firms (or their affiliates) that the Company selects in connection with the particular redemption, and their respective successors; provided that if any of them ceases to be a Primary Treasury Dealer, the Company will substitute another nationally
            recognized investment banking firm (or its affiliate) that is a Primary
              Treasury Dealer.

           

          “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the
            Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 3:30 p.m., New York
            City time, on the third Business Day preceding the date that the applicable redemption notice is first mailed or sent.

           

          “Remaining Scheduled Payments” means the remaining payments of principal of and interest on the Notes that would be due after the redemption date but for such redemption if
            the Notes matured on the Par Call Date. If the redemption date is not an interest payment date, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued thereon to the
            redemption date.

           

          
            
              


            8

          

          Notwithstanding the foregoing, at any time on or after the Par Call Date, upon notice pursuant to Section 3.02 of the Indenture, the Company may, at its option, redeem some or all of the Notes at a redemption price
            equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the applicable redemption date.

           

          Except pursuant to this Section 6, the Notes shall not be redeemable at the Company’s option prior to the Par Call Date.

           

          Notwithstanding the foregoing, in connection with any offer to purchase or tender offer for the Notes at any time, if Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly
            tender and do not withdraw such Notes in such offer and the Company, or any third party making such tender offer in lieu of the Company, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third
            party will have the right upon not less than 10 nor more than 60 days’ prior notice, given not more than 60 days following such purchase date, to redeem (with respect to the Company) or purchase (with respect to a third party) all Notes that
            remain outstanding following such purchase at a price equal to the price paid to each other Holder in such tender offer (which may be less than par) plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if
            any, thereon, to, but excluding, the applicable redemption date or purchase date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling on or prior to such
            redemption date or purchase date.

           

          Unless the Company defaults in the payment of the redemption price, on and after
            the applicable redemption date, interest will cease to accrue on the Notes or portions of the Notes called for redemption.

           

          Calculation of the redemption price will be made by the Company or on the Company’s behalf by such person as the Company shall designate; provided that such calculation or
            the correctness thereof shall not be a duty or obligation of the Trustee.

           

          7.           Notice of Redemption

          

           

            

          Notice of redemption will be mailed by first-class mail (or delivered by electronic transmission in
            accordance with the Applicable Procedures of DTC) at least 10 but not more than 60 days before the redemption
            date to each Holder of Notes to be redeemed at such Holder’s registered address, except that redemption notices may be mailed more
            than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. If such notice of redemption is subject to satisfaction of one
            or more conditions precedent, such notice will state that, in the Company’s discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including
            by electronic transmission) as any or all such conditions are satisfied (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions have not
            been satisfied by the redemption date, or by the redemption date as so delayed.  Notes in denominations larger than $2,000 principal amount





            may be redeemed in part but only in whole multiples of $1,000 in excess of $2,000. If money sufficient to pay the redemption price of, and accrued and
            unpaid interest on, all the Notes (or portions thereof) to be
            redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and in
            accordance with the Indenture, on and after such date interest ceases to accrue on such Notes (or such portions thereof) called for redemption.

          8.           Put Provisions

           

          

          Subject to Section 4.03 of the Indenture, within 30 days following the occurrence of a Change of Control Triggering Event with respect to the Notes, each Holder shall have the right to require that the Company make
            an offer to purchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase plus accrued and unpaid interest, if any, to, but excluding, the date of purchase.

           

          If the Change of Control purchase date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest to the Change of Control purchase date will be paid
            on the Change of Control purchase date to the Person in whose name a Note is registered at the close of business on such record date.

           

          If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change
            of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 10 nor more than 60 days’ prior
            notice (provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer as described above) to redeem (with respect to the Company) or purchase
            (with respect to a third party) all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest, if any, on the Notes that remain
            outstanding to, but excluding, the date of redemption, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling on or prior to the redemption date or purchase
            date.

           

          A “Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event with respect to the Notes.

           

          9.           Denominations; Transfer; Exchange

           

          

          The Notes are in registered form without coupons in minimum denominations of $2,000 principal













            amount and any integral multiple of $1,000 in excess of $2,000. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate
            endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in
            part, the portion of the Note not to be redeemed) or any Notes for a period of 15 days before a selection of Notes to be redeemed, or between a record date and the related interest payment date.

          10.         Persons Deemed Owners

           

          

          The registered Holder of this Note may be treated as the owner of it for all purposes.

           

          11.         Unclaimed Money

           

          

          If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and
            not to the Trustee for payment.

           

          12.         Discharge and Defeasance

           

          

          Subject to certain conditions, the Company at any time shall be entitled to terminate some or













            all of its obligations under the Notes and the Indenture if the Company deposits with the Trustee money or Government Securities for the payment of principal and interest on the Notes to redemption or maturity, as the case may be.

            also be waived with the written consent of the Holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes). Subject to certain exceptions set forth in the Indenture, without the consent of any Noteholder,
            the Company, and the Trustee shall be entitled to amend the Indenture or the Notes to cure any ambiguity, omission, defect or inconsistency, as determined in good faith by the Company, or to provide for the assumption by a successor Person of the obligations of
            the Company or any Guarantor under the Indenture, or to provide for uncertificated Notes in addition to or in place of certificated Notes, or to add guarantees with respect to the Notes or to secure the Notes, or to




            add to the covenants of the Company or any Subsidiary for the benefit of the Noteholders or to surrender any right or power conferred upon the Company or any Subsidiary, or to make any change that does not materially adversely affect the
            rights of any Noteholder, as determined in good faith by the Company, or to comply with any requirement of the SEC in connection with any required qualification of the Indenture under the Trust
            Indenture Act of 1939, as amended, or to conform the text of the Indenture, the Guarantees or the Notes to any provision in the Offering Memorandum under the heading “Description of notes,” as determined in good faith by the Company, or to
            release a Guarantor from its Guarantee when permitted by the terms of the Indenture, or to provide for successor trustees or to add to or change any provisions to the extent necessary to appoint a separate trustee for the Notes, or to make any
            amendment to provisions of the Indenture relating to the transfer and legending of the Notes as permitted by the
              Indenture, including, without limitation, to facilitate the issuance and administration of the Notes, or, if Incurred in compliance with the Indenture, Additional Notes.

          14.         Defaults and Remedies

           

          

          Under the Indenture, Events of Default include (a) default for 30 consecutive days in payment of interest on the Notes; (b) default in payment of principal on the
            Notes at maturity, upon optional redemption pursuant to paragraph 6 of the Notes, upon declaration of acceleration
            or otherwise, or failure by the Company to
            redeem or purchase Notes when required; (c) failure




            by the Company to comply with other agreements in the Indenture or the Notes, in certain cases subject to notice and lapse of time; (d) certain accelerations (including failure to pay within any grace period after final maturity) of other Debt of the Company, any Guarantor or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $150.0 million; (e) certain events of bankruptcy, insolvency or reorganization of the Company, any Guarantor or any Significant Subsidiary; (f) certain
            judgments or decrees for the payment of money in excess of $250.0 million and (g) a Guarantee ceases to be in full force and effect or a
              Guarantor denies or disaffirms its obligations under its Guarantee.  If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in principal amount of the Notes may declare all
            the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency relating to the Company
            are Events of Default which will result in the Notes being due and payable immediately upon the occurrence of
            such Events of Default.

           

          Noteholders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders













            of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Noteholders notice of any continuing Default (except a Default in payment
            of principal or interest) if it determines that
            withholding notice is in the interest of the Holders.

           

          15.         Trustee Dealings with the Company

           

          

          Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture,
            in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

           

          16.         No Recourse Against Others

           

          

          A past, present or future director, officer, employee, incorporator, member, partner or shareholder of the Company,
            any Guarantor or the Trustee, as such, shall not have any liability for any obligations of the Company or any Guarantor (other than the Company in respect of the Notes and each Guarantor in respect of its Guarantee) under the Notes, the Guarantees or the Indenture or




            for any claim based on, in respect of or by reason of, such obligations or their creation. By accepting a
            Note, each Noteholder waives and releases all such liability. The waiver and release are part of the consideration for the issuance of
            the Notes.

          Pursuant to a recommendation promulgated by the Committee on Uniform Note Identification Procedures the Company has caused CUSIP numbers to be
            printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience

          The undersigned represents and warrants to you that:

           

          1.  We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities




              Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for




            the account of such an institutional “accredited investor” at least $250,000 principal amount of the Notes, and
            we are acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be
            capable of evaluating the merits and risks of our investment in the Notes, and we invest in or purchase securities similar to the Notes in the normal course of our business. We, and any accounts for which we are acting, are each
            able to bear the economic risk of our or its investment.

           

          
            
              


          

          2.  We understand that the Notes have not
              been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of
              any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the date of original issue and the last date on which the Company




              or any affiliate of the Company was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (i) to the Company, (ii) in the United States
              to a person whom the seller reasonably believes is a qualified institutional buyer in a transaction meeting the requirements of Rule 144A, (iii) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities
                Act that is an institutional accredited investor purchasing for its own account or for the account of an institutional accredited investor, in
              each case in a minimum principal amount of the Notes of $250,000, (iv) outside the United States in a transaction complying with the provisions of Rule 904 under the Securities Act, (v) pursuant to an exemption from registration under the Securities Act provided by Rule 144 (if available) or (vi) pursuant to an effective registration statement under the Securities Act,
              in each of cases (i) through (vi) subject to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or




              their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction
              Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (iii) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Notes for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve




              the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Notes pursuant




              to clause (iii), (iv) or (v) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Company and the Trustee.

          SUPPLEMENTAL INDENTURE (this “Supplemental

            among                                               (the “Guarantor”), [a subsidiary of] CoStar Group, Inc. (or its permitted successor), a Delaware
            corporation (the “Company”) and Wilmington Trust, National Association, as trustee under the Indenture referred to below (the “Trustee”).

          WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of July 1, 2020 providing for
            the issuance of 2.800% Senior Notes due 2030 (the “Notes”);

           

          WHEREAS, the Indenture provides that under certain circumstances the Guarantor will execute and deliver to the Trustee a supplemental












              indenture pursuant to which the Guarantor will unconditionally guarantee all of the Company’s obligations under the Notes and the Indenture on
            the terms and conditions set forth herein (the “Guarantee”); and

           

          WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

           

          NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guarantor and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows:

          2.  AGREEMENT TO GUARANTEE.  The Guarantor hereby agrees to provide an unconditional
            Guarantee on the terms and subject to the conditions set forth in this Guarantee and in the
            Indenture including but not limited to Article 10 thereof.

           

          4.  NO RECOURSE AGAINST OTHERS.  No past, present or future director, officer,

            obligations of the Company or any Guarantor under

            or this Supplemental Indenture or for any
            claim based on, in respect of, or by reason of, such obligations or their creation.  Each Holder of the Notes by accepting a Note waives and releases all such liability.  The
            waiver and release are part of the consideration for issuance of the Notes.
