      WHEREAS, the Issuer has heretofore executed and delivered an Indenture, dated as of April 9, 2020 (the “Base Indenture”), among the Issuer, Parent and the Trustee, providing for
        the issuance from time to time of one or more Series of the Issuer’s Notes;

       

      WHEREAS, Section 2.01 of the Base Indenture permits the creation of the Notes of any Series with the terms and in the form permitted in Sections 2.02 of the Base Indenture to be established in a supplemental indenture
        to the Base Indenture;

       

      WHEREAS, the Issuer has requested the Trustee to join with it and the Guarantors in the execution of this First Supplemental Indenture in order to supplement the Base Indenture by, among other things, establishing the
        forms and certain terms of a Series of Notes to be known as the Issuer’s “3.500% Senior Secured Notes due 2025” and adding certain provisions thereto for the benefit of the Holders of the Notes of such Series;

       

      WHEREAS, the Issuer has furnished the Trustee with a duly authorized and executed Company Order dated April 9, 2020 authorizing the execution of this First Supplemental Indenture and the issuance of the Notes
        established hereby; and

       

      WHEREAS, all things necessary to make this First Supplemental Indenture a valid, binding and enforceable agreement of the Issuer, the Guarantors and the Trustee and a valid supplement to the Base Indenture have been
        done.

       

      NOW, THEREFORE, the Issuer, the Guarantors and the Trustee agree as follows for the benefit of each other and for the equal and ratable benefit of the Holders of the Notes established hereby:

        THE NOTES

       

      Section 2.01          Creation of the
          Notes; Designations.

       

      In accordance with Section 2.01 of the Base Indenture, the Issuer hereby creates a Series of Notes issued pursuant to the Indenture.  The Notes of this Series shall be known and designated as the “3.500% Senior Secured
        Notes due 2025” of the Issuer.  The Notes of this Series shall be entitled to the benefits of the Note Guarantee of each Guarantor signatory hereto, or that may hereafter execute a supplemental indenture in accordance with Section 4.09 of the Base
        Indenture, each such Note Guarantee to be governed by Article X of the Base Indenture (including, without limitation, the provisions for release of such Note Guarantee in respect of the Notes of this Series pursuant to Section 10.04 of the Base
        Indenture).

       

      Section 2.02          Forms Generally.

       

      (a)          General.  The Notes of this Series and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto.  The Notes of this Series may have notations,
        legends or endorsements required by law, stock exchange rule or usage.  Each Note of this Series will be dated the date of its authentication.  The Notes of this Series shall be in minimum denominations of $2,000 and integral multiples of $1,000.

       

      The terms and provisions contained in the Notes of this Series will constitute, and are hereby expressly made, a part of this First Supplemental Indenture and the Issuer, the Guarantors and the Trustee, by their
        execution and delivery of this First Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby.  However, to the extent any provision of any such Note conflicts with the express provisions of this First
        Supplemental Indenture, the provisions of this First Supplemental Indenture shall govern and be controlling.

       

      (b)          Global Notes.  Notes of this Series issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of
        Interests in the Global Note” attached thereto).  Notes of this Series issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of
        Interests in the Global Note” attached thereto).  Each Global Note will represent such of the outstanding Notes of this Series as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding
        Notes of this Series from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes of this Series represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and
        redemptions.  Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes of this Series represented thereby will be made by the Trustee or the Notes Custodian, at the
        direction of the Trustee, in accordance with instructions given by the Holder thereof.

      The aggregate principal amount of Notes of this Series which shall be authenticated and delivered on the Series Issue Date under the Indenture shall be $3,000,000,000; provided,
        however, that subject to the Issuer’s compliance with Section 4.06 of the Base Indenture, the Issuer from time to time, without giving notice to or seeking the consent of the Holders of Notes of this Series,
        may issue additional notes (the “Additional Notes”) in any amount having the same terms as the Notes of this Series in all respects, except for the issue date, the issue price, the initial Interest Payment
        Date and rights under a related registration rights agreement, if any.  Any such Additional Notes shall be authenticated by the Trustee upon receipt of a Company Order to that effect, and when so authenticated, will constitute “Notes” for all purposes of the Indenture and will (together with all other Notes of this Series issued under the Indenture) constitute a single Series of Notes under the Indenture; provided that if such Additional Notes are not fungible with the Notes of this Series for U.S. federal income tax purposes, as applicable, as determined by the Issuer, such Additional Notes may have a separate CUSIP number.

       

      (a)          The Notes of this Series issued on the Series Issue Date will be issued at an issue price of 99.977% of the principal amount thereof.

       

      (b)          The principal amount of the Notes of this Series is due and payable in full as set forth in Exhibit A.

       

      (c)          The rate or rates at which the Notes shall bear interest, the date or dates from which such interest shall accrue, the interest payment dates on which any such interest shall
        be payable and the regular record date for any interest payable on any interest payment date, in each case, shall be as set forth in the form of the Note as set forth in Exhibit A.

       

      (d)          Other than as provided in Article III of this First Supplemental Indenture, the Notes of this Series shall not be redeemable.

       

      (e)          The Notes of this Series will initially be evidenced by one or more Global Notes issued in the name of Cede & Co., as nominee of The Depository Trust Company.

       

      (f)           The terms and provisions of Appendix A of the Base Indenture shall apply to the Notes of this Series.

       

      Section 2.04          Agreement to Guarantee.

       

      The Guarantors hereby agree, jointly and severally, to unconditionally guarantee the Issuer’s obligations under the Notes and the Indenture on the terms and subject to the conditions set forth in the Indenture
        including but not limited to ARTICLE X of the Base Indenture.

       

      ARTICLE III

        REDEMPTION AND PREPAYMENT

       

      Section 3.01          Optional Redemption.

       

      The Notes of this Series may be redeemed, in whole, or from time to time in part, subject to the conditions and at the redemption prices set forth in Section 5 of the form of Note set forth in Exhibit A hereto,
        which are hereby incorporated by reference and made part of this First Supplemental Indenture, together with accrued and unpaid interest, if any, thereon to, but not including, the redemption date, and in accordance with Article III of the Base
        Indenture.

        hereof) be read together with this First Supplemental Indenture and shall have the same effect over the Notes of this Series, in the same manner as if the provisions of the Base Indenture and this First Supplemental Indenture were contained in the
        same instrument.

       

      (b)          In all other respects, the Base Indenture is confirmed by the parties hereto as supplemented by the terms of this First Supplemental Indenture.

                  INTEREST.

                


        

      

       

      Interest (computed on the basis of a 360-day year comprised of twelve 30-day months) shall accrue on the principal amount of this Note from and including April 9, 2020 until maturity at a rate per annum equal to
        3.500%.

       

      The Issuer promises to pay interest and Additional Interest, if any, semi-annually in arrears on April 15 and October 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day
        (each, an “Interest Payment Date”).  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 the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date,
        interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 15, 2020.  If an
        Interest Payment Date or the maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next succeeding Business Day as if made on the date the payment was due, and no interest shall
        accrue for the intervening period.

      The Issuer 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 April 1 or October 1 next preceding the Interest Payment Date,
        even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.14 of the Base Indenture with respect to defaulted interest.  The Notes will be payable as to principal, premium, if
        any, and interest at the office or agency of the Issuer maintained for such purpose within the City and State of New York, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth
        in the books and records of the Registrar; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all
        Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent.  Such payment will be in such money of the United States of America as at the time of payment is legal tender for
        payment of public and private debts. [The Holder of a Definitive Note is not required to surrender such Definitive Note to the Trustee in order to receive payment of principal at maturity.  Such Definitive Note, after payment has been made, shall
        be cancelled without the requirement of presentation.]3

      Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying Agent and Registrar.  The Issuer may change any Paying Agent or Registrar without notice to any Holder.  The Issuer
        or any of its Subsidiaries may act in any such capacity.

      The Issuer issued the Notes pursuant to an Indenture dated as of April 9, 2020 (the “Base Indenture”) among the Issuer, the Guarantors and the Trustee, as
        amended and supplemented with respect to the Notes by the First Supplemental Indenture dated as of April 9, 2020 (the “First Supplemental Indenture”; the Base
        Indenture, as amended and supplemented with respect to the Notes by the First Supplemental Indenture, the “Indenture”).

      

      

      The terms of the Notes include those stated in the Indenture and, following the qualification of the Base Indenture under the Trust Indenture Act, those made part of the Indenture by reference to
        the Trust Indenture Act.  The Notes are subject to all such terms, and Holders are referred to the Indenture and, to the extent so included in the Indenture, to the Trust Indenture Act for a statement of such terms.  To the extent any provision of
        this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.  The Notes are senior secured obligations of the Issuer.  The Indenture does not limit the aggregate principal amount
        of Notes that may be issued thereunder.

      

      

      The Issuer’s obligations under the Notes are unconditionally guaranteed on a senior secured basis, to the extent set forth in the Indenture and the Security Documents, by each of the Secured
        Guarantors and on a senior unsecured basis by each of the Unsecured Guarantors to the extent set forth in the Indenture.

                OPTIONAL REDEMPTION.

              


      

       

      Prior to March 15, 2025, the Notes will be redeemable, in whole or in part, at the Issuer’s option, at any time or from time to time, on at least 15 days’ but not more than 60 days’ prior notice to the holders of the
        Notes, at a redemption price equal to the greater of:

       

      •          100% of the principal amount thereof; or

       

      •          the sum, as calculated by the Issuer, of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed (assuming that such Notes matured on
        March 15, 2025), exclusive of interest accrued to, but not including, the redemption date, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the
        applicable Treasury Rate (as defined below) plus 50 basis points (any excess of the amount described in this bullet point over the amount described in the immediately preceding bullet point, the “Make-Whole Premium”).

       

      On or after March 15, 2025, the Notes will be redeemable, in whole or in part, at the Issuer’s option, at any time or from time to time, on at least 15 days’ but not more than 60 days’ prior notice to the holders of
        the Notes, at a redemption price equal to 100% of the principal amount thereof.

      We will also pay the accrued and unpaid interest on the principal amount being redeemed to, but not including, the redemption date.

       

      “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Bank as having a constant maturity comparable to the remaining term
        (“Remaining Life”) of the Notes (assuming that the Notes matured on March 15, 2025) 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 comparable maturity to the remaining term of the Notes (assuming that the Notes matured on March 15, 2025).

       

      “Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the
        highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Bank obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

       

      “Independent Investment Bank” means one of the Reference Treasury Dealers that the Issuer
        appoints to act as the Independent Investment Bank from time to time.

       

      “Reference Treasury Dealer” means (1) each of Barclays Capital Inc., Deutsche Bank Securities Inc. and Goldman Sachs & Co. LLC and their respective
        successors, unless any of them ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case we will substitute another Primary Treasury Dealer and
        (2) any other Primary Treasury Dealer(s) the Issuer selects.

      

      

      “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the
        Independent Investment Bank, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Bank by such Reference Treasury
        Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

      

      

      “Treasury Rate” means, with respect to any redemption date, (i) the yield, calculated as the average of the five most
          recent daily rates published in the statistical release(s) designated “H.15” or any successor publication which is published by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. 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 March 15, 2025, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line
          basis, rounding to the nearest month); or (ii) if the release referred to above (or any successor release) is not published during the week preceding the calculation date or does not contain the yields referred to above, the rate per annum equal
          to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
          redemption date. The Treasury Rate will be calculated at 5:00 p.m. (New York City time) on the third business day preceding such redemption date. As used in the immediately preceding sentence and in the definition of “Reference Treasury Dealer
          Quotations” above, the term “business day” means any day that is not a Saturday, Sunday or other day on which commercial banks in New York City are authorized or obligated by law or executive order to close.

      

        

      
        Exhibit A-9

        
          


      

      The Trustee shall have no responsibility for calculating the redemption price for the Notes.

      

      

      Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date. At or
        before 10:00 a.m. (New York time) on the redemption date, the Issuer will deposit with the Trustee or a paying agent money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on such date. If less than all of
        the Notes are to be redeemed, the Notes to be redeemed shall be selected in accordance with the procedures of DTC.

      

      

      For the avoidance of doubt, the requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the
        Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

      

      

      
        
          	

                	(6)	
                  MANDATORY REDEMPTION.

                


        

      

       

      The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

       

      
        
          
            	

                  	(7)	
                    NOTICE OF REDEMPTION.

                  


          

        

         

      

      
        Notice of redemption will be sent at least 15 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed, except that redemption notices may be sent
          or 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. Notes in denominations larger than $2,000 may be redeemed in part but
          only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. In connection with any redemption of Notes, any such notice of redemption may, at the Issuer’s discretion, state that such redemption is subject to
          one or more conditions precedent, including, but not limited to, completion of an equity offering, other offering, issuance of Indebtedness or other corporate transaction or event. In addition, if such notice of redemption is subject to
          satisfaction of one or more conditions precedent, such notice may state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Issuer 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 (or waived by the Issuer in its sole discretion) by the redemption date (whether the
          original redemption date or the redemption date so delayed).

                    REPURCHASE AT THE OPTION OF HOLDER.

                  


          

        

      

       

      If there is a Change of Control Triggering Event, the Issuer will be required to make a Change of Control Offer to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess
        thereof) of such Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of purchase, subject to the
        rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date for periods prior to such repurchase date pursuant to Section 4.08 of the Base Indenture. Within 30 days following any Change of Control
        Triggering Event, the Issuer will send a notice to each Holder and the Trustee describing the transaction or transactions and identifying the Rating Event that together constitute the Change of Control Triggering Event, offering to repurchase Notes
        on the Change of Control Payment Date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent and setting forth the procedures governing the Change of Control Offer as required
        by the Indenture.

                      REGISTRATION RIGHTS.

                    


            

          

        

      

       

      The Holder of this Note is entitled to the benefits of a Registration Rights Agreement, including with respect to Additional Interest, pursuant to which, subject to the terms and conditions
        thereof, the Issuer and the Guarantors are obligated to consummate the Registered Exchange Offer, whereby the Exchange Notes, having terms identical in all material respects to the Notes (except that the Exchange Note will not contain terms with
        respect to transfer restrictions or Additional Interest) will be offered in exchange for surrender of the Notes.

      The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The
        Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer
        need not exchange or register the transfer or exchange of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange or register the transfer of
        any Notes (i) for a period beginning at the opening of business 15 days immediately preceding the sending of notice of redemption of Notes selected for redemption and ending at the close of business on the day such notice is sent or (ii) during the
        period between a record date and the corresponding Interest Payment Date.

                          PERSONS DEEMED OWNERS.  The registered Holder of a Note may be treated as its owner for all purposes.

                        


                

              

            

          

        

      

      

      

      (12)        AMENDMENT, SUPPLEMENT AND WAIVER.  The Indenture, the Intercreditor Agreement, the Security Documents, the Notes and the Note Guarantees may be amended,
        supplemented or waived as provided in Article IX of the Base Indenture and in the Intercreditor Agreement and the Security Documents where applicable.

       

      
        Exhibit A-11

        
          


      

      (13)        DEFAULTS AND REMEDIES.  If an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the
        Issuer, any of its Significant Subsidiaries or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary) and is continuing, the Trustee or the Holders of at least 30% in principal amount of the outstanding Notes, in
        each case, by notice to the Issuer, may declare the principal of, premium, if any, and accrued but unpaid interest, if any, on all the Notes to be due and payable; provided that no such declaration may be
        made with respect to or as a result of any action taken, and reported publicly or to holders of Notes, more than two years prior to such declaration. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of
        the Issuer, any of its Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and
        payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes
        and its consequences. The requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture, this Supplemental Indenture or the applicable
        Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

       

      (14)        TRUSTEE DEALINGS WITH ISSUER.  The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer
        or any Affiliate of the Issuer with the same rights it would have if it were not Trustee.

       

      (15)        NO RECOURSE AGAINST OTHERS.  No past, present or future director, officer, member, manager, partner, employee, incorporator or stockholder of the Issuer or any
        Guarantor, as such, will have any liability for any obligations of the Issuer or the Guarantors under the Notes, the Indenture, the Intercreditor Agreement, the Security Documents, the Note Guarantees or for any claim based on, in respect of, or by
        reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

       

      (16)        AUTHENTICATION.  This Note will not be valid until authenticated by the manual, facsimile or electronic (including PDF) signature of the Trustee or an
        authenticating agent.

       

      (17)        ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right
        of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

       

      (18)        CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has
        caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained
        in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. No redemption will be affected by any defect in or omission of such numbers.
