2.200% Senior Note Due 2019

DISCOVERY COMMUNICATIONS, LLC, a Delaware limited liability company (the “ Company ”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. Cash interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from September 21, 2017. The Company will pay interest semi-annually in arrears on each Interest Payment Date, commencing March 20, 2018. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date is not a Business Day, then the related payment of interest for such Interest Payment Date shall be paid on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date and no further interest shall accrue as a result of such delay.

The Company shall pay interest on overdue principal from time to time on demand at the rate borne by the Securities and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful.

The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities to the Trustee to collect principal payments. The Company shall 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 (“ U.S. Legal Tender ”). Payment of principal of (and premium, if any) and any such interest on this Security will be made at the Corporate Trust Office of the Trustee in Boston, Massachusetts or at any other office or agency designated by the Company for such purpose; provided that at the option of the Company payment of interest may be made by check mailed to the address of the Holder entitled thereto as such address appears in the Security register. However, the payments of interest, and any portion of the principal (other than interest payable at maturity or on any redemption or repayment date or the final payment of principal) shall be made by the Paying Agent, upon receipt from the Company of immediately available funds by 12:30 p.m., New York City time (or such other time as may be agreed to between the Company and the Paying Agent or the Company), directly to a Holder (by Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to the Trustee 15 days prior to such payment date requesting that such payment will be so made and designating the bank account to which such payments shall be so made and in the case of payments of principal surrenders the same to the Trustee in exchange for a Security or Securities aggregating the same principal amount as the unredeemed principal amount of the Securities surrendered.

Initially, U.S. Bank National Association (the “ Trustee ”) will act as Paying Agent. The Company may change any Paying Agent without notice to the Holders.

The Company issued the Securities under an Indenture, dated as of August 19, 2009 (the “ Indenture ”), among the Company, the Guarantor and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “ TIA ”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern.

The Company, the Guarantor and the Trustee entered into an Eleventh Supplemental Indenture, dated as of September 21, 2017 setting forth certain terms of the Securities pursuant to Section 2.04 of the Indenture (the “ Supplemental Indenture ”). The Supplemental Indenture imposes certain limitations on the incurrence of liens and certain sale and leaseback transactions and limits the Company’s ability to consolidate, merge, convey, transfer or lease its properties and assets substantially as an entirety. To the extent the terms of the Supplemental Indenture are inconsistent with the Indenture or this Security, the terms of the Supplemental Indenture shall govern.

The payment by the Company of the principal of, and premium and interest on, the Securities is irrevocably and unconditionally guaranteed on a senior basis by the Guarantor.

The Securities are redeemable, in whole or in part, at the option of the Company, at any time and from time to time, at the redemption price described in the Supplemental Indenture.

If a Change of Control Triggering Event (as defined in the Supplemental Indenture) occurs, unless the Company has exercised its right to redeem the Securities, Holders of the Securities will have the right to require the Company to repurchase all or a portion of their Securities pursuant to the offer described in the Supplemental Indenture at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase, subject to the rights of Holders of Securities on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date.

The Securities are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Company need not issue, authenticate, register the transfer of or exchange any Securities or portions thereof for a period of 15 days before such series is selected for redemption, nor need the Company register the transfer or exchange of any Security selected for redemption in whole or in part.

The registered Holder of a Security shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company or the Guarantor at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Company may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Securities and in the Indenture with respect to the Securities, in each case upon satisfaction of certain conditions specified in the Indenture.

Subject to certain exceptions, the Securities and the provisions of the Indenture relating to the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities of all series then outstanding affected by such amendment or supplement (voting as one class), and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders of a majority in aggregate principal amount of all the Securities of such series, each series voting as a separate class, (or of all the Securities, as the case may be, voting as a single class) then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities, or make any other change that does not adversely affect the rights of any Holder of a Security.

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Company or the Guarantor) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities of this series then outstanding (voting as a separate class) may declare all of the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. If a bankruptcy Event of Default with respect to the Company or the Guarantor occurs and is continuing, the entire principal amount of the Securities then outstanding and interest accrued thereon, if any, shall immediately become due and payable. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company as if it were not the Trustee.

No stockholder, director, officer, employee, member or incorporator, as such, of the Company, of the Guarantor or any successor Person thereof shall have any liability for any obligation under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security.

Customary abbreviations may be used in the name of a Holder of a Security 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).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

Cash interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from September 21, 2017. The Company will pay interest semi-annually in arrears on each Interest Payment Date, commencing March 20, 2018. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date is not a Business Day, then the related payment of interest for such Interest Payment Date shall be paid on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date and no further interest shall accrue as a result of such delay.

The Company shall pay interest on overdue principal from time to time on demand at the rate borne by the Securities and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful.

The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities to the Trustee to collect principal payments. The Company shall 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 (“ U.S. Legal Tender ”). Payment of principal of (and premium, if any) and any such interest on this Security will be made at the Corporate Trust Office of the Trustee in Boston, Massachusetts or at any other office or agency designated by the Company for such purpose; provided that at the option of the Company payment of interest may be made by check mailed to the address of the Holder entitled thereto as such address appears in the Security register. However, the payments of interest, and any portion of the principal (other than interest payable at maturity or on any redemption or repayment date or the final payment of principal) shall be made by the Paying Agent, upon receipt from the Company of immediately available funds by 12:30 p.m., New York City time (or such other time as may be agreed to between the Company and the Paying Agent or the Company), directly to a Holder (by Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to the Trustee 15 days prior to such payment date requesting that such payment will be so made and designating the bank account to which such payments shall be so made and in the case of payments of principal surrenders the same to the Trustee in exchange for a Security or Securities aggregating the same principal amount as the unredeemed principal amount of the Securities surrendered.

Initially, U.S. Bank National Association (the “ Trustee ”) will act as Paying Agent. The Company may change any Paying Agent without notice to the Holders.

The Company issued the Securities under an Indenture, dated as of August 19, 2009 (the “ Indenture ”), among the Company, the Guarantor and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “ TIA ”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern.

The Company, the Guarantor and the Trustee entered into an Eleventh Supplemental Indenture, dated as of September 21, 2017 setting forth certain terms of the Securities pursuant to Section 2.04 of the Indenture (the “ Supplemental Indenture ”). The Supplemental Indenture imposes certain limitations on the incurrence of liens and certain sale and leaseback transactions and limits the Company’s ability to consolidate, merge, convey, transfer or lease its properties and assets substantially as an entirety. To the extent the terms of the Supplemental Indenture are inconsistent with the Indenture or this Security, the terms of the Supplemental Indenture shall govern.

The payment by the Company of the principal of, and premium and interest on, the Securities is irrevocably and unconditionally guaranteed on a senior basis by the Guarantor.

Prior to February 20, 2023 (the “ Par Call Date ”), the Securities are redeemable, in whole or in part, at the option of the Company, at any time and from time to time, at the redemption price described in the Supplemental Indenture.

On and after the Par Call Date, the Securities shall be redeemable, in whole or in part, at the option of the Company at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest on the principal amount being redeemed to the date of redemption.

If a Change of Control Triggering Event (as defined in the Supplemental Indenture) occurs, unless the Company has exercised its right to redeem the Securities, Holders of the Securities will have the right to require the Company to repurchase all or a portion of their Securities pursuant to the offer described in the Supplemental Indenture at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase, subject to the rights of Holders of Securities on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date.

In the event that (a) the Merger Agreement (as defined in the Supplemental Indenture) is terminated on or at any time prior to August 30, 2018 or (b) the Merger (as defined in the Supplemental Indenture) is not consummated on or at any time prior to August 30, 2018, the Company shall redeem all of the Securities at a price equal to 101% of the aggregate outstanding principal amount of the Securities plus accrued and unpaid interest from the last date on which interest was paid or, if interest has not been paid, the date of original issuance of the Securities to, but not including, the Special Mandatory Redemption Date (as defined in the Supplemental Indenture).

The Securities are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Company need not issue, authenticate, register the transfer of or exchange any Securities or portions thereof for a period of 15 days before such series is selected for redemption, nor need the Company register the transfer or exchange of any Security selected for redemption in whole or in part.

The registered Holder of a Security shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company or the Guarantor at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Company may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Securities and in the Indenture with respect to the Securities, in each case upon satisfaction of certain conditions specified in the Indenture.

Subject to certain exceptions, the Securities and the provisions of the Indenture relating to the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities of all series then outstanding affected by such amendment or supplement (voting as one class), and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders of a majority in aggregate principal amount of all the Securities of such series, each series voting as a separate class, (or of all the Securities, as the case may be, voting as a single class) then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities, or make any other change that does not adversely affect the rights of any Holder of a Security.

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Company or the Guarantor) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities of this series then outstanding (voting as a separate class) may declare all of the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. If a bankruptcy Event of Default with respect to the Company or the Guarantor occurs and is

continuing, the entire principal amount of the Securities then outstanding and interest accrued thereon, if any, shall immediately become due and payable. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company as if it were not the Trustee.

No stockholder, director, officer, employee, member or incorporator, as such, of the Company, of the Guarantor or any successor Person thereof shall have any liability for any obligation under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security.

Customary abbreviations may be used in the name of a Holder of a Security 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).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

The laws of the State of New York shall govern the Indenture and this Security thereof.

Holders must surrender Securities to the Trustee to collect principal payments.

Initially, U.S. Bank National Association (the “ Trustee ”) will act as Paying Agent. The Company may change any Paying Agent without notice to the Holders.

The Company issued the Securities under an Indenture, dated as of August 19, 2009 (the “ Indenture ”), among the Company, the Guarantor and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “ TIA ”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern.

The Company, the Guarantor and the Trustee entered into an Eleventh Supplemental Indenture, dated as of September 21, 2017 setting forth certain terms of the Securities pursuant to Section 2.04 of the Indenture (the “ Supplemental Indenture ”). The Supplemental Indenture imposes certain limitations on the incurrence of liens and certain sale and leaseback transactions and limits the Company’s ability to consolidate, merge, convey, transfer or lease its properties and assets substantially as an entirety. To the extent the terms of the Supplemental Indenture are inconsistent with the Indenture or this Security, the terms of the Supplemental Indenture shall govern.

The payment by the Company of the principal of, and premium and interest on, the Securities is irrevocably and unconditionally guaranteed on a senior basis by the Guarantor.

Prior to March 20, 2037 (the “ Par Call Date ”), the Securities are redeemable, in whole or in part, at the option of the Company, at any time and from time to time, at the redemption price described in the Supplemental Indenture.

On and after the Par Call Date, the Securities shall be redeemable, in whole or in part, at the option of the Company at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest on the principal amount being redeemed to the date of redemption.

If a Change of Control Triggering Event (as defined in the Supplemental Indenture) occurs, unless the Company has exercised its right to redeem the Securities, Holders of the Securities will have the right to require the Company to repurchase all or a portion of their Securities pursuant to the offer described in the Supplemental Indenture at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase, subject to the rights of Holders of Securities on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date.

In the event that (a) the Merger Agreement (as defined in the Supplemental Indenture) is terminated on or at any time prior to August 30, 2018 or (b) the Merger (as defined in the Supplemental Indenture) is not consummated on or at any time prior to August 30, 2018, the Company shall redeem all of the Securities at a price equal to 101% of the aggregate outstanding principal amount of the Securities plus accrued and unpaid interest from the last date on which interest was paid or, if interest has not been paid, the date of original issuance of the Securities to, but not including, the Special Mandatory Redemption Date (as defined in the Supplemental Indenture).

The Securities are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Company need not issue, authenticate, register the transfer of or exchange any Securities or portions thereof for a period of 15 days before such series is selected for redemption, nor need the Company register the transfer or exchange of any Security selected for redemption in whole or in part.

The registered Holder of a Security shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company or the Guarantor at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Company may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Securities and in the Indenture with respect to the Securities, in each case upon satisfaction of certain conditions specified in the Indenture.

Subject to certain exceptions, the Securities and the provisions of the Indenture relating to the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities of all series then outstanding affected by such amendment or supplement (voting as one class), and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders of a majority in aggregate principal amount of all the Securities of such series, each series voting as a separate class, (or of all the Securities, as the case may be, voting as a single class) then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities, or make any other change that does not adversely affect the rights of any Holder of a Security.

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Company or the Guarantor) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities of this series then outstanding (voting as a separate class) may declare all of the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. If a bankruptcy Event of Default with respect to the Company or the Guarantor occurs and is

continuing, the entire principal amount of the Securities then outstanding and interest accrued thereon, if any, shall immediately become due and payable. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company as if it were not the Trustee.

No stockholder, director, officer, employee, member or incorporator, as such, of the Company, of the Guarantor or any successor Person thereof shall have any liability for any obligation under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security.

Customary abbreviations may be used in the name of a Holder of a Security 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).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

The laws of the State of New York shall govern the Indenture and this Security thereof.

In addition, the Company may, from time to time, without notice to or the consent of the Holders of the Notes, create and issue additional Notes ranking equally and ratably with the Notes issued on the date hereof in all respects (or in all respects except for the payment of interest accruing prior to the issue date of such additional Notes or except for the first payment of interest following the issue date of such additional Notes), so that such additional Notes shall be

5

consolidated and form a single series with such series of Notes issued on the date hereof and shall have the same terms as to status, redemption or otherwise as such series of Notes issued on the date hereof, provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number.

Section 2.02. Maturity . The principal amount of the Notes shall be payable on September 20, 2019.

Section 2.03. Form and Payment . (a) The Notes shall be issued as global notes, only in fully registered book-entry form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

(b) Principal, premium, if any, and/or interest, if any, on the global notes representing the Notes shall be made to the Paying Agent (defined below) which in turn shall make payment to The Depository Trust Company as the Depositary with respect to the Notes of such series or its nominee.

Interest on the Notes shall be payable quarterly in arrears on March 20, June 20, September 20 and December 20 of each year, commencing on December 20, 2017 (each an “ Interest Payment Date ”), to the Holders in whose names the Notes are registered at the close of business on the March 5, June 5, September 5 and December 5 immediately preceding such Interest Payment Date. Interest on the Notes shall be computed on the basis of a 360-day year and the actual number of days that have elapsed in the applicable Interest Period. If any Interest Payment Date is not a Business Day, then the related payment of interest for such Interest Payment Date shall be paid on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date and no further interest shall accrue as a result of such delay.

Section 2.05. Floating Rate Interest Calculation . The Notes shall bear interest for each Interest Period at a rate determined by the calculation agent (the “ Calculation Agent ”), which will initially be the Trustee. If the Trustee is unable or unwilling to continue to act as the Calculation Agent for the Notes, or if it fails to calculate properly the interest rate on such series of Notes for any Interest Period, the Company shall appoint another leading trust company, commercial or investment bank or other financial

6

institution to act as calculation agent in its place for such Notes. The Calculation Agent may not resign its duties without a successor having been appointed. For so long as the institution serving as Trustee is serving in the role as Calculation Agent, the Calculation Agent shall be entitled to all of the rights, privileges and immunities afforded the Trustee under the Indenture in the performance of its duties under this Supplemental Indenture.

The interest rate for the Notes for the initial Interest Period shall be 2.03611%. The interest determination date for any subsequent Interest Period shall be the second London Business Day immediately preceding the first day of such Interest Period (each an “ Interest Determination Date ”). Promptly upon determination, the Calculation Agent shall inform the Company of the interest rate for the next Interest Period.

All percentages resulting from any calculation of any interest rate for the Notes shall be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 3.876545% (or .03876545) would be rounded to 3.87655% (or .0387655)), and all U.S. dollar amounts will be rounded to the nearest cent, with one-half cent being rounded upward. Each calculation of the interest rate on the Notes by the Calculation Agent will (in the absence of manifest error) be final and binding on the Holders of the Notes, the Trustee and the Company.

The interest rate on the Notes shall in no event be higher than the maximum rate permitted by New York law or other applicable state law as such law may be modified by United States law of general application. Additionally, the interest rate on the Notes shall in no event be lower than zero percent.

Cash interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from September 21, 2017. The Company will pay interest quarterly in arrears on each Interest Payment Date, commencing December 20, 2017. Interest will be computed on the basis of a 360-day year and the actual number of days that have elapsed in the applicable Interest Period. If any Interest Payment Date is not a Business Day, then the related payment of interest for such Interest Payment Date shall be paid on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date and no further interest shall accrue as a result of such delay.

The Company shall pay interest on overdue principal from time to time on demand at the rate borne by the Securities and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful.

The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities to the Trustee to collect principal payments. The Company shall 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 (“ U.S. Legal Tender ”).

However, the payments of interest, and any portion of the principal (other than interest payable at maturity or on any redemption or repayment date or the final payment of principal) shall be made by the Paying Agent, upon receipt from the Company of immediately available funds by 12:30 p.m., New York City time (or such other time as may be agreed to between the Company and the Paying Agent or the Company), directly to a Holder (by Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to the Trustee 15 days prior to such payment

Initially, U.S. Bank National Association (the “ Trustee ”) will act as Paying Agent. The Company may change any Paying Agent without notice to the Holders.

The Company issued the Securities under an Indenture, dated as of August 19, 2009 (the “ Indenture ”), among the Company, the Guarantor and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “ TIA ”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern.

The Company, the Guarantor and the Trustee entered into a Twelfth Supplemental Indenture, dated as of September 21, 2017 setting forth certain terms of the Securities pursuant to Section 2.04 of the Indenture (the “ Supplemental Indenture ”). The Supplemental Indenture imposes certain limitations on the incurrence of liens and certain sale and leaseback transactions and limits the Company’s ability to consolidate, merge, convey, transfer or lease its properties and assets substantially as an entirety. To the extent the terms of the Supplemental Indenture are inconsistent with the Indenture or this Security, the terms of the Supplemental Indenture shall govern.

The payment by the Company of the principal of, and premium and interest on, the Securities is irrevocably and unconditionally guaranteed on a senior basis by the Guarantor.

If a Change of Control Triggering Event (as defined in the Supplemental Indenture) occurs, unless the Company has exercised its right to redeem the Securities, Holders of the Securities will have the right to require the Company to repurchase all or a portion of their Securities pursuant to the offer described in the Supplemental Indenture at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase, subject to the rights of Holders of Securities on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date.

The Securities are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Company need not issue, authenticate, register the transfer of or exchange any Securities or portions thereof for a period of 15 days before such series is selected for redemption, nor need the Company register the transfer or exchange of any Security selected for redemption in whole or in part.

The registered Holder of a Security shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company or the Guarantor at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Company may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Securities and in the Indenture with respect to the Securities, in each case upon satisfaction of certain conditions specified in the Indenture.

Subject to certain exceptions, the Securities and the provisions of the Indenture relating to the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities of all series then outstanding affected by such amendment or supplement (voting as one class), and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders of a majority in aggregate principal amount of all the Securities of such series, each series voting as a separate class, (or of all the Securities, as the case may be, voting as a single class) then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities, or make any other change that does not adversely affect the rights of any Holder of a Security.

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Company or the Guarantor) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities of this series then outstanding (voting as a separate class) may declare all of the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. If a bankruptcy Event of Default with respect to the Company or the Guarantor occurs and is continuing, the entire principal amount of the Securities then outstanding and interest accrued thereon, if any, shall immediately become due and payable. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company as if it were not the Trustee.

No stockholder, director, officer, employee, member or incorporator, as such, of the Company, of the Guarantor or any successor Person thereof shall have any liability for any obligation under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security.

Customary abbreviations may be used in the name of a Holder of a Security 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).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities.

The laws of the State of New York shall govern the Indenture and this Security thereof.

The Company will pay interest annually in arrears on each Interest Payment Date, commencing September 20, 2018.

This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association.

If, on or after the date of the issuance of this Security, sterling is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond the Company’s control, then all payments in respect of the Notes shall be made in U.S. dollars until sterling is again available to the Company. In such circumstances, the amount payable on any date in sterling will be converted into U.S. dollars on the basis of the most recently available market exchange rate for sterling.

The Company issued the Securities under an Indenture, dated as of August 19, 2009 (the “ Indenture ”), among the Company, the Guarantor and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “ TIA ”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern.

The Company, the Guarantor, the Trustee and Elavon Financial Services DAC, UK Branch, as Paying Agent, entered into a Thirteenth Supplemental Indenture, dated as of September 21, 2017 setting forth certain terms of the Securities pursuant to Section 2.04 of the Indenture (the “ Supplemental Indenture ”). The Supplemental Indenture imposes certain limitations on the incurrence of liens and certain sale and leaseback transactions and limits the Company’s ability to consolidate, merge, convey, transfer or lease its properties and assets substantially as an entirety. To the extent the terms of the Supplemental Indenture are inconsistent with the Indenture or this Security, the terms of the Supplemental Indenture shall govern.

The payment by the Company of the principal of, and premium and interest on, the Securities is irrevocably and unconditionally guaranteed on a senior basis by the Guarantor.

Prior to June 20, 2024 (the “ Par Call Date ”), the Securities are redeemable, in whole or in part, at the option of the Company, at any time and from time to time, at the redemption price described in the Supplemental Indenture.

On and after the Par Call Date, the Securities shall be redeemable, in whole or in part, at the option of the Company at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest on the principal amount being redeemed to the date of redemption.

The Securities are redeemable by the Company in whole, but not in part, upon the occurrence of certain developments affecting U.S. taxation described in the Supplemental Indenture at a redemption price equal to 100% of their principal amount, together with accrued and unpaid interest on those Securities to, but not including, the date fixed for redemption.

If a Change of Control Triggering Event (as defined in the Supplemental Indenture) occurs, unless the Company has exercised its right to redeem the Securities, Holders of the Securities will have the right to require the Company to repurchase all or a portion of their Securities pursuant to the offer described in the Supplemental Indenture at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase, subject to the rights of Holders of Securities on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date.

In the event that (a) the Merger Agreement (as defined in the Supplemental Indenture) is terminated on or at any time prior to August 30, 2018 or (b) the Merger (as defined in the Supplemental Indenture) is not consummated on or at any time prior to August 30, 2018, the Company shall redeem all of the Securities at a price equal to 101% of the aggregate outstanding principal amount of the Securities plus accrued and unpaid interest from the last date on which interest was paid or, if interest has not been paid, the date of original issuance of the Securities to, but not including, the Special Mandatory Redemption Date (as defined in the Supplemental Indenture).

The Company shall, subject to the exceptions and limitations set forth in the Supplemental Indenture, pay as additional interest on Securities such additional amounts as are necessary in order that the net payment by the Company of the principal of and interest on the Securities to a Holder of the Securities who is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in the Securities to be then due and payable.

As used in this Section 9, the term “United States” means the United States of America, the states of the United States, and the District of Columbia, and the term “United States person” means any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, a corporation, partnership or other entity created or organized in or under the laws of the United States, any state of the United States of the District of Columbia, or any estate or trust the income of which is subject to United States federal income taxation regardless of its source.

The Securities are in registered form, without coupons, in minimum denominations of £100,000 and integral multiples of £1,000 in excess thereof. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Company need not issue, authenticate, register the transfer of or exchange any Securities or portions thereof for a period of 15 days before such series is selected for redemption, nor need the Company register the transfer or exchange of any Security selected for redemption in whole or in part.

The registered Holder of a Security shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company or the Guarantor at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Company may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Securities and in the Indenture with respect to the Securities, in each case upon satisfaction of certain conditions specified in the Indenture, as supplemented by the Thirteenth Supplemental Indenture.

Subject to certain exceptions, the Securities and the provisions of the Indenture relating to the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities of all series then outstanding affected by such amendment or supplement (voting as one class), and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders of a majority in aggregate principal amount of all the Securities of such series, each series voting as a separate class, (or of all the Securities, as the case may be, voting as a single class) then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities, or make any other change that does not adversely affect the rights of any Holder of a Security.

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Company or the Guarantor) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities of this series then outstanding (voting as a separate class) may declare all of the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. If a bankruptcy Event of Default with respect to the Company or the Guarantor occurs and is continuing, the entire principal amount of the Securities then outstanding and interest accrued thereon, if any, shall immediately become due and payable. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it

has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company as if it were not the Trustee.

No stockholder, director, officer, employee, member or incorporator, as such, of the Company, of the Guarantor or any successor Person thereof shall have any liability for any obligation under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security.
