provisions of the Indenture, without notice to or the consent of the Holders of the Notes of the applicable series, create and issue pursuant to the Indenture additional Notes of such series (in the case of the 2023 Notes, the “2023
Additional Notes”, in the case of the 2028 Notes, the “2028 Additional Notes” and, together with the 2028 Additional Notes, the “Additional Notes”) having terms and conditions identical to those of the

REDEMPTION OF SECURITIES 

Section 401. Special Mandatory Redemption. 

(a) In the event the proposed Cavium Acquisition is not consummated on or prior to March 31, 2019, or if the Merger Agreement is
terminated any time prior to such date (any of the foregoing, a “Special Mandatory Redemption Event”), then the Company shall be required to redeem each series of the Notes on the Special Mandatory Redemption Date (such redemption,
a “Special Mandatory Redemption”) at a redemption price equal to 101% of the principal amount of the Notes plus accrued and unpaid interest thereon to, but not including, the Special Mandatory Redemption Date. The “Special
Mandatory Redemption Date” shall be a date selected by the Company that is no later than 30 days following any Special Mandatory Redemption Event. Notwithstanding the foregoing, installments of interest on Notes that are due and payable on
interest payment dates falling on or prior to the Special Mandatory Redemption Date will be payable on such interest payment dates to the registered Holders of such Notes as of the close of business on the relevant Record Dates in accordance with
the terms of the Notes of such series and the Indenture. 
 (b) The Company shall cause the notice of Special Mandatory Redemption to be
sent, with a copy to the Trustee, within five Business Days after the occurrence of a Special Mandatory Redemption Event to each Holder. 

(c) The notice of Special Mandatory Redemption shall identify the Notes to be redeemed and shall state: (1) the Special Mandatory
Redemption Date and (2) the Redemption Price. 
 (d) If funds sufficient to pay the Special Mandatory Redemption price of the Notes to
be redeemed on the Special Mandatory Redemption Date are deposited with the Trustee or a Paying Agent on or before such Special Mandatory Redemption Date, on and after such Special Mandatory Redemption Date, such Notes will cease to bear interest.

 (e) The provisions of Section 1104 of the Base Indenture shall not apply to Special Mandatory Redemptions of the Notes pursuant to
this Section 401 of this First Supplemental Indenture. 

  
 11 








 Section 402. Optional Redemption. (a) Subject to Section 102 hereof, the
provisions of Article XI of the Base Indenture, as supplemented by the provisions of this First Supplemental Indenture, shall apply to the Notes. 

(b) At any time before the 2023 Par Call Date, the 2023 Notes shall be redeemable, as a whole at any time or from time to time in part, at the
Company’s option, at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the applicable 2023 Notes to be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments of such 2023
Notes, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury
Rate plus 25 basis points, plus accrued and unpaid interest thereon to, but excluding, the redemption date for such 2023 Notes. The redemption price shall be determined by the Company and the Trustee shall have no duty to verify any such
determination made by the Company. On or after the 2023 Par Call Date, the 2023 Notes shall be redeemable, as a whole at any time or from time to time in part, at the Company’s option, at a redemption price equal to 100% of the aggregate
principal amount of the applicable Notes to be redeemed, plus in each case, accrued and unpaid interest thereon to, but excluding, the redemption date for such Notes. 

(c) At any time before the 2028 Par Call Date, the 2028 Notes shall be redeemable, as a whole at any time or from time to time in part, at the
Company’s option, at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the applicable 2028 Notes to be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments of such 2028
Notes, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury
Rate plus 30 basis points, plus accrued and unpaid interest thereon to, but excluding, the redemption date for such 2028 Notes. The redemption price shall be determined by the Company and the Trustee shall have no duty to verify any such
determination made by the Company. On or after the 2028 Par Call Date, the 2028 Notes shall be redeemable, as a whole at any time or from time to time in part, at the Company’s option, at a redemption price equal to 100% of the aggregate
principal amount of the applicable Notes to be redeemed, plus in each case, accrued and unpaid interest thereon to, but excluding, the redemption date for such Notes. 

(d) Notwithstanding Section 402(b) and Section 402(c) above, installments of interest on a series of Notes that are due and payable

applicable series and the Indenture. 
 (e) On and after the redemption date for the Notes of the applicable series, interest shall cease to
accrue on such Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the redemption price and accrued interest, if any. If less than all of the Notes of a series are to be redeemed, the Notes of such
series to be redeemed shall be selected pro rata or by lot or by such other method as the Trustee shall deem fair and appropriate (including, in the case of Notes represented by a Global Security, in accordance with the procedures of the
Depositary); provided, however, that in no event shall Notes of a principal amount of $2,000 or less be redeemed in part. 

  
 12 








 (f) Notice of any redemption shall be delivered at least 15 days but not more than 60 days before
the redemption date to each Holder of the Notes of the applicable series to be redeemed (with a copy to the Trustee). The Trustee shall, at the Company’s written request (delivered to the Trustee at least five Business Days prior to the date
such notice is to be sent (or such shorter period as the Trustee may agree) with a copy of such notice) give the notice of redemption in the Company’s name and at the Company’s expense. Such notice shall state the redemption price (if
known) or the formula pursuant to which the redemption price is to be determined if the redemption price cannot be determined at the time the notice is given. If the redemption price cannot be determined at the time such notice is to be given, the
actual redemption price, calculated as described above in Section 402(b) or Section 402(c), as applicable, shall be set forth in an Officer’s Certificate delivered to the Trustee no later than two Business Days prior to the redemption
date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest, if any, to, but
excluding, the redemption date. A notice of redemption may, at the Company’s option and discretion, be subject to one or more conditions precedent. 

Section 403. Purchase of Notes upon a Change of Control Repurchase Event. 

(a) If a Change of Control Repurchase Event occurs with respect to a series of Notes, unless the Company shall have exercised its option to
redeem the Notes of such series pursuant to Section 402 of this First Supplemental Indenture, each Holder of the Notes of such series shall have the right to require the Company to repurchase all or any part (equal to $2,000 and multiples of
$1,000 in excess thereof) of that Holder’s Notes of such series at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes to be repurchased plus any accrued and unpaid interest on the Notes of such series to,
but excluding, the repurchase date. Within 30 days following any Change of Control Repurchase Event with respect to a series of Notes or, at the option of the Company, prior to any Change of Control, but after the public announcement of the Change
of Control or event that may constitute the Change of Control, the Company shall deliver a notice (the “Change of Control Notice”) to each Holder of such series of Notes, with a copy to the Trustee, describing the transaction or
transactions that constitute or may constitute the Change of Control Repurchase Event and offering (the “Change of Control Offer”) to repurchase the Notes of such series on the repurchase date specified in the notice at the option
of the Holders of such series of Notes, which date (the “Change of Control Payment Date”) shall be no earlier than 30 days and no later than 60 days from the date such notice is delivered. The Change of Control Notice shall, if
delivered prior to the date of consummation of the Change of Control, state that the Company’s obligation to repurchase the Notes of the applicable series is conditioned on a Change of Control Repurchase Event occurring on or prior to the
Change of Control Payment Date. 
 (b) On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(i) accept for payment all the Notes or portions of the Notes properly tendered pursuant to the Change of Control Notice; 

(ii) deposit with the Paying Agent or tender agent appointed for such purpose an amount equal to the aggregate repurchase price
in respect of all the Notes or portions of the Notes properly tendered; and 

  
 13 








 (iii) deliver or cause to be delivered to the Trustee the Notes properly
accepted, together with an Officer’s Certificate stating the aggregate principal amount of Notes being repurchased by the Company. 

(c) The Paying Agent or tender agent shall promptly deliver to each Holder of Notes properly tendered the repurchase price for the Notes, and
the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered. 

(d) Notwithstanding the foregoing in this Section 403, the Company shall not be required to make a Change of Control Offer in connection
with a Change of Control Repurchase Event if a third party makes such an offer in connection with such Change of Control Repurchase Event in the manner and at the times required and otherwise in compliance with the requirements for such a Change of
Control Offer made by the Company, and such third party purchases all Notes properly tendered and not withdrawn under its offer. 
 (e) If
Holders of not less than 95% in aggregate principal amount of a series of Notes then outstanding 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 pursuant to Section 403(d) above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 30 days nor more than 60 days’ prior written notice to the
Holders of such series of Notes (with a copy to the Trustee), given not more than 30 days following such purchase pursuant to the Change of Control Offer described in Section 403(b) above, to redeem all Notes of such series that remain
outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding the redemption date (subject to the right of Holders of record on a Record
Date to receive interest on the relevant interest payment date). 
 (f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any repurchase of the Notes as a result of a Change of
Control Repurchase Event. To the extent the provisions of any such securities laws or regulations conflict with this Section 403, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 403 by virtue thereof; provided that the Company otherwise uses commercially reasonable efforts to permit Holders to exercise their rights and to fulfill its obligations in the time and in the manner
specified in this Section 403 to the extent permitted by such securities laws or regulations.

June 22 and December 22 of each year, beginning on December 22, 2018. Interest on the Securities shall accrue from the most recent interest payment date to or for which interest has been paid or duly provided for or, if no interest
has been paid or duly provided for, from June 22, 2018. Interest shall be computed on the basis of a 360-day year consisting of twelve 30-day months. 

(2) Method of Payment. The Company shall pay interest on the Securities (except Defaulted Interest) to the persons who are registered
Holders of Securities at the close of business on the Record Date immediately preceding the interest payment date even though such Securities are canceled after the Record Date and on or before the interest payment date. Holders of certificated
Securities must surrender certificated Securities to a Paying Agent 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. Payment of principal of and premium, if any, and interest on this Note shall be made in immediately available funds to the Depositary or its nominee, as the case may be, as the registered Holder of this Global Security. 

(3) Paying Agent, Transfer Agent and Securities Registrar. Initially, U.S. Bank National Association, a national banking association,
as trustee under the Indenture (the “Trustee”), shall act as Paying Agent, transfer agent and Securities Registrar. The Company may change any Paying Agent, transfer agent, Securities Registrar or
co-registrar without notice to the Holders. The Company may act as Paying Agent, transfer agent, Securities Registrar or co-registrar. 

(4) Indenture. This Note is a “Security” and the Notes are “Securities” under the Indenture (as defined below). The
Company issued the Securities under an Indenture dated as of June 22, 2018 (the “Base Indenture”), as supplemented by the First Supplemental Indenture dated as of June 22, 2018 (the “First Supplemental
Indenture” and, together with the Base Indenture, the “Indenture”), in each case between the Company and the Trustee. The Securities are unsecured general obligations of the Company and constitute the “4.200% Senior
Notes due 2023”, initially limited to $500,000,000 in aggregate principal amount. The Notes are not guaranteed by any Person. 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. Code Sections 77aaa-77bbbb) (the “TIA”). Capitalized terms used herein but not defined herein are used as defined in the Indenture. The Securities are subject to all such terms, and Holders
are referred to the Indenture and the TIA 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. 

  
 A-4 








 (5) Special Mandatory Redemption. In the event the proposed Cavium Acquisition is not
consummated on or prior to March 31, 2019, or if the Merger Agreement is terminated any time prior to such date (any of the foregoing, a “Special Mandatory Redemption Event”), then the Company shall be required to redeem the
Securities on the Special Mandatory Redemption Date (such redemption, a “Special Mandatory Redemption”) at a redemption price equal to 101% of the principal amount of the Securities plus accrued and unpaid interest thereon to, but
not including, the Special Mandatory Redemption Date. The “Special Mandatory Redemption Date” shall be a date selected by the Company that is no later than 30 days following any Special Mandatory Redemption Event. Notwithstanding
the foregoing, installments of interest on Securities that are due and payable on interest payment dates falling on or prior to the Special Mandatory Redemption Date will be payable on such interest payment dates to the registered Holders of such
Securities as of the close of business on the relevant Record Dates in accordance with the terms of the Securities and the Indenture. 
 The
Company shall cause the notice of Special Mandatory Redemption to be sent, with a copy to the Trustee, within five Business Days after the occurrence of a Special Mandatory Redemption Event to each Holder. 

If funds sufficient to pay the Special Mandatory Redemption price of the Securities to be redeemed on the Special Mandatory Redemption Date
are deposited with the Trustee or a Paying Agent on or before such Special Mandatory Redemption Date, on and after such Special Mandatory Redemption Date, such Securities will cease to bear interest. 

(6) Optional Redemption. The Company may redeem the Securities in whole at any time or from time to time in part prior to their Stated
Maturity, at its option, pursuant to the following terms: 
 (a) At any time before May 22, 2023, the redemption price
shall be equal to the greater of (i) 100% of the aggregate principal amount of the Securities to be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments of such Securities, discounted to the redemption date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 25 basis points, plus accrued and
unpaid interest thereon to, but excluding, the redemption date. The redemption price shall be determined by the Company and the Trustee shall have no duty to verify any such determination made by the Company. 

(b) At any time on or after May 22, 2023, the redemption price shall be equal to 100% of the aggregate principal amount of
the Securities to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date. 
 Notwithstanding the
foregoing, installments of interest on Securities that are due and payable on interest payment dates falling on or prior to a redemption date shall be payable on the interest payment date to the registered Holders as of the close of business on the
relevant Record Date in accordance with the provisions of the Securities and the Indenture. 
 On and after the redemption date for the
Securities, interest shall cease to accrue on such Securities or any portion thereof called for redemption, unless the Company defaults in the payment of the redemption price and accrued interest, if any. On or before the redemption date


  
 A-5 








 
for the Securities, the Company shall deposit with the Trustee or a Paying Agent funds sufficient to pay the redemption price of the Securities to be redeemed on the redemption date, and (except
if the redemption date shall be an interest payment date) accrued interest, if any. If less than all of the Securities are to be redeemed, the Securities to be redeemed shall be selected pro rata or by lot or by such method as the Trustee shall deem
fair and appropriate, in accordance with the procedures of the Depositary; provided, however, that in no event shall Securities of a principal amount of $2,000 or less be redeemed in part. 

Notice of any redemption shall be delivered at least 15 days but not more than 60 days before the redemption date to each Holder of the
Securities to be redeemed (with a copy to the Trustee). The Trustee shall, at the Company’s written request (delivered to the Trustee at least five Business Days prior to the date such notice is to be sent (or such shorter period as the Trustee
may agree) with a copy of such notice) give the notice of redemption in the Company’s name and at the Company’s expense. Such notice shall state the redemption price (if known) or the formula pursuant to which the redemption price is to be
determined if the redemption price cannot be determined at the time the notice is given. If the redemption price cannot be determined at the time such notice is to be given, the actual redemption price, calculated as set forth in the Indenture,
shall be set forth in an Officer’s Certificate delivered to the Trustee no later than two Business Days prior to the redemption date. Notice of redemption having been given as provided in the Indenture, the Securities called for redemption
shall become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. 

(7) Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs with respect to the Securities, unless the
Company shall have exercised its option pursuant to Section (6) hereof to redeem the Securities, each Holder of the Securities shall have the right to require the Company to repurchase all or any part (equal to $2,000 and multiples of $1,000 in
excess thereof) of that Holder’s Securities at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities to be repurchased plus any accrued and unpaid interest on such Securities to, but excluding, the
repurchase date. 
 Within 30 days following any Change of Control Repurchase Event with respect to the Securities or, at the option of the
Company, prior to any Change of Control, but after the public announcement of the Change of Control or event that may constitute the Change of Control, the Company shall deliver a notice (the “Change of Control Notice”) to each
Holder of the Securities, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering (the “Change of Control Offer”) to repurchase
such Securities on the repurchase date specified in the notice at the option of the Holders, which date (the “Change of Control Payment Date”) shall be no earlier than 30 days and no later than 60 days from the date such notice is
delivered. The Change of Control Notice shall, if delivered prior to the date of consummation of the Change of Control, state that the Company’s obligation to repurchase the Securities is conditioned on a Change of Control Repurchase Event
occurring on or prior to the Change of Control Payment Date. 

  
 A-6 








 On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(i) accept for payment all the Securities or portions of the Securities properly tendered pursuant to the Change of Control
Notice; 
 (ii) deposit with the Paying Agent or tender agent appointed for such purpose an amount equal to the aggregate
repurchase price in respect of all the Securities or portions of the Securities properly tendered; and 
 (iii) deliver or
cause to be delivered to the Trustee the Securities properly accepted, together with an Officer’s Certificate stating the aggregate principal amount of the Securities being repurchased by the Company. 

If Holders of not less than 95% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities
in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company pursuant to Section 403(d) of the First Supplemental Indenture, purchases all of the Securities validly tendered and not
withdrawn by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days’ prior written notice to the Holders of the Securities (with a copy to the trustee), given not more than 30 days following such purchase
pursuant to the Change of Control Offer described above, to redeem all Securities that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any,
to, but excluding, the redemption date (subject to the right of Holders of record on a Record Date to receive interest on the relevant interest payment date). 

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any repurchase of the Securities as a result of a Change of Control Repurchase Event. To the extent the provisions of any such
securities laws or regulations conflict with this Section (7), the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section (7) by virtue thereof; provided
that the Company otherwise uses commercially reasonable efforts to permit Holders to exercise their rights and to fulfill its obligations in the time and in the manner specified in this Section (7) to the extent permitted by such securities
laws or regulations. 
 (8) Denominations; Transfer; Exchange. The Securities are in registered form without coupons in minimum
denominations of $2,000 and any multiple of $1,000 in excess thereof. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Securities Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Company shall not be required (A) to transfer or exchange any Securities subject to redemption during a
period beginning at the opening of business 15 days before the day of the electronic delivery or mailing of a notice of redemption and ending at the close of business on the day of such electronic delivery or mailing or (B) to register the
transfer of or exchange any Security so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

  
 A-7 








 (9) Defeasance. Subject to certain conditions as provided in the Indenture, the Company at
any time may terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money and/or U.S. Government Obligations for the payment of principal and interest on the Securities to their
Stated Maturity. 
 (10) Persons Deemed Owners. The registered Holder of a Security may be treated as its owner for all purposes,
except that interest (other than Defaulted Interest) shall be paid to the Person that was the registered Holder on the relevant Record Date for such payment of interest. 

(11) Amendments and Waivers. Subject to certain exceptions, (i) the Indenture or the Securities may be amended or supplemented
with respect to this series with the consent of the Holders of a majority in principal amount of the Securities; and (ii) any existing default with respect to the Securities may be waived with the consent of the Holders of a majority in
principal amount of the Securities. Without the consent of any Holder of this series, the Indenture or the Securities may be amended or supplemented in accordance with Section 901 of the Base Indenture to, among other things, cure any
ambiguity, defect or inconsistency, to provide for assumption of Company obligations to Holders of this series or to provide for uncertificated Securities, to provide for guarantees with respect to, or security for, the Securities, or to comply with
amendments to the TIA or to add additional covenants, or to surrender any right or power conferred upon the Company, or to make any change that does not adversely affect the rights of any Holder of this series. 

(12) Remedies. If an Event of Default with respect to the Securities occurs and is continuing, the Trustee or Holders of at least 25%
in aggregate principal amount of the Securities may, by notice in writing to the Company (and the Trustee if given by the Holders), declare all the Securities to be due and payable immediately. Holders may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may require security or indemnity before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the outstanding Securities may direct
the Trustee in its exercise of any trust or power with respect to the Securities. The Trustee may withhold from Holders of this series notice of any Default or Event of Default (except a Default in payment of principal or interest) if it determines
in good faith that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. 

(13) Trustee Dealings with Company. Subject to the provisions of the TIA, the Trustee under the Indenture, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. The Trustee shall initially be U.S. Bank National
Association. 
 (14) No Recourse Against Others. A director, officer, incorporator or shareholder, as such, past, present or future
of the Company or any successor corporation of the Company, shall not have any liability for any obligations of the Company 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 by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

(15) Authentication. This Security shall not be valid until authenticated by the manual signature of an authorized signatory of the
Trustee or an authenticating agent.

(b) At any time on or after March 22, 2028, the redemption price shall be equal to 100% of the aggregate principal amount
of the Securities to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date. 
 Notwithstanding the
foregoing, installments of interest on Securities that are due and payable on interest payment dates falling on or prior to a redemption date shall be payable on the interest payment date to the registered Holders as of the close of business on the
relevant Record Date in accordance with the provisions of the Securities and the Indenture. 
 On and after the redemption date for the
Securities, interest shall cease to accrue on such Securities or any portion thereof called for redemption, unless the Company defaults in the payment of the redemption price and accrued interest, if any. On or before the redemption date


  
 B-5 








 
for the Securities, the Company shall deposit with the Trustee or a Paying Agent funds sufficient to pay the redemption price of the Securities to be redeemed on the redemption date, and (except
if the redemption date shall be an interest payment date) accrued interest, if any. If less than all of the Securities are to be redeemed, the Securities to be redeemed shall be selected pro rata or by lot or by such method as the Trustee shall deem
fair and appropriate, in accordance with the procedures of the Depositary; provided, however, that in no event shall Securities of a principal amount of $2,000 or less be redeemed in part. 

Notice of any redemption shall be delivered at least 15 days but not more than 60 days before the redemption date to each Holder of the
Securities to be redeemed (with a copy to the Trustee). The Trustee shall, at the Company’s written request (delivered to the Trustee at least five Business Days prior to the date such notice is to be sent (or such shorter period as the Trustee
may agree) with a copy of such notice) give the notice of redemption in the Company’s name and at the Company’s expense. Such notice shall state the redemption price (if known) or the formula pursuant to which the redemption price is to be
determined if the redemption price cannot be determined at the time the notice is given. If the redemption price cannot be determined at the time such notice is to be given, the actual redemption price, calculated as set forth in the Indenture,
shall be set forth in an Officer’s Certificate delivered to the Trustee no later than two Business Days prior to the redemption date. Notice of redemption having been given as provided in the Indenture, the Securities called for redemption
shall become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. 

(7) Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs with respect to the Securities, unless the
Company shall have exercised its option pursuant to Section (6) hereof to redeem the Securities, each Holder of the Securities shall have the right to require the Company to repurchase all or any part (equal to $2,000 and multiples of $1,000 in
excess thereof) of that Holder’s Securities at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities to be repurchased plus any accrued and unpaid interest on such Securities to, but excluding, the
repurchase date. 
 Within 30 days following any Change of Control Repurchase Event with respect to the Securities or, at the option of the
Company, prior to any Change of Control, but after the public announcement of the Change of Control or event that may constitute the Change of Control, the Company shall deliver a notice (the “Change of Control Notice”) to each
Holder of the Securities, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering (the “Change of Control Offer”) to repurchase
such Securities on the repurchase date specified in the notice at the option of the Holders, which date (the “Change of Control Payment Date”) shall be no earlier than 30 days and no later than 60 days from the date such notice is
delivered. The Change of Control Notice shall, if delivered prior to the date of consummation of the Change of Control, state that the Company’s obligation to repurchase the Securities is conditioned on a Change of Control Repurchase Event
occurring on or prior to the Change of Control Payment Date. 

  
 B-6 








 On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(i) accept for payment all the Securities or portions of the Securities properly tendered pursuant to the Change of Control
Notice; 
 (ii) deposit with the Paying Agent or tender agent appointed for such purpose an amount equal to the aggregate
repurchase price in respect of all the Securities or portions of the Securities properly tendered; and 
 (iii) deliver or
cause to be delivered to the Trustee the Securities properly accepted, together with an Officer’s Certificate stating the aggregate principal amount of the Securities being repurchased by the Company. 

If Holders of not less than 95% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities
in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company pursuant to Section 403(d) of the First Supplemental Indenture, purchases all of the Securities validly tendered and not
withdrawn by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days’ prior written notice to the Holders of the Securities (with a copy to the trustee), given not more than 30 days following such purchase
pursuant to the Change of Control Offer described above, to redeem all Securities that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any,
to, but excluding, the redemption date (subject to the right of Holders of record on a Record Date to receive interest on the relevant interest payment date). 

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any repurchase of the Securities as a result of a Change of Control Repurchase Event. To the extent the provisions of any such
securities laws or regulations conflict with this Section (7), the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section (7) by virtue thereof; provided
that the Company otherwise uses commercially reasonable efforts to permit Holders to exercise their rights and to fulfill its obligations in the time and in the manner specified in this Section (7) to the extent permitted by such securities
laws or regulations. 
 (8) Denominations; Transfer; Exchange. The Securities are in registered form without coupons in minimum
denominations of $2,000 and any multiple of $1,000 in excess thereof. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Securities Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Company shall not be required (A) to transfer or exchange any Securities subject to redemption during a
period beginning at the opening of business 15 days before the day of the electronic delivery or mailing of a notice of redemption and ending at the close of business on the day of such electronic delivery or mailing or (B) to register the
transfer of or exchange any Security so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

  
 B-7 








 (9) Defeasance. Subject to certain conditions as provided in the Indenture, the Company at
any time may terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money and/or U.S. Government Obligations for the payment of principal and interest on the Securities to their
Stated Maturity. 
 (10) Persons Deemed Owners. The registered Holder of a Security may be treated as its owner for all purposes,
except that interest (other than Defaulted Interest) shall be paid to the Person that was the registered Holder on the relevant Record Date for such payment of interest. 

(11) Amendments and Waivers. Subject to certain exceptions, (i) the Indenture or the Securities may be amended or supplemented
with respect to this series with the consent of the Holders of a majority in principal amount of the Securities; and (ii) any existing default with respect to the Securities may be waived with the consent of the Holders of a majority in
principal amount of the Securities. Without the consent of any Holder of this series, the Indenture or the Securities may be amended or supplemented in accordance with Section 901 of the Base Indenture to, among other things, cure any
ambiguity, defect or inconsistency, to provide for assumption of Company obligations to Holders of this series or to provide for uncertificated Securities, to provide for guarantees with respect to, or security for, the Securities, or to comply with
amendments to the TIA or to add additional covenants, or to surrender any right or power conferred upon the Company, or to make any change that does not adversely affect the rights of any Holder of this series. 

(12) Remedies. If an Event of Default with respect to the Securities occurs and is continuing, the Trustee or Holders of at least 25%
in aggregate principal amount of the Securities may, by notice in writing to the Company (and the Trustee if given by the Holders), declare all the Securities to be due and payable immediately. Holders may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may require security or indemnity before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the outstanding Securities may direct
the Trustee in its exercise of any trust or power with respect to the Securities. The Trustee may withhold from Holders of this series notice of any Default or Event of Default (except a Default in payment of principal or interest) if it determines
in good faith that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. 

(13) Trustee Dealings with Company. Subject to the provisions of the TIA, the Trustee under the Indenture, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. The Trustee shall initially be U.S. Bank National
Association. 
 (14) No Recourse Against Others. A director, officer, incorporator or shareholder, as such, past, present or future
of the Company or any successor corporation of the Company, shall not have any liability for any obligations of the Company 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 by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

(15) Authentication. This Security shall not be valid until authenticated by the manual signature of an authorized signatory of the
Trustee or an authenticating agent.
