all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the
Depository or impair, as between the Depository and its Participants, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Note.

(a) Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to the Security Registrar with a request: 

(i) to register the transfer of such Definitive Notes; or 

(ii) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations, the
Security Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Notes surrendered for transfer or exchange: 

(A) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company
and the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and 
 (B) are
accompanied by the following additional information and documents, as applicable: 
 (x) if such Definitive Notes are being
delivered to the Security Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect (in the form set forth on the reverse side of the Initial Note); or 

(y) if such Definitive Notes are being transferred to the Company, a certification to that effect (in the form set forth on
the reverse side of the Initial Note); or 

  
 6 

 (C) if such Definitive Notes are being transferred pursuant to an exemption from
registration in accordance with Rule 144 under the Securities Act or in reliance upon another exemption from the registration requirements of the Securities Act, (i) a certification to that effect (in the form set forth on the reverse side of
the Initial Note) and (ii) if the Company or Security Registrar so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in
Section 2.5(e)(i) of this Supplemental Indenture. 
 (b) Restrictions on Transfer of a Definitive Note for a Beneficial Interest in a
Global Note. A Definitive Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Note, duly endorsed or accompanied by a
written instrument of transfer in form reasonably satisfactory to the Company and the Security Registrar, together with: 

(i) certification (in the form set forth on the reverse side of the Initial Note) that such Definitive Note is being
transferred (a) to a QIB in accordance with Rule 144A or (b) outside the United States in an offshore transaction within the meaning of Regulation S and in compliance with Rule 904 under the Securities Act; and 

(ii) written instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its books
and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depository account to be credited with such
increase, then the Trustee shall cancel such Definitive Note and cause, or direct the Notes Custodian to cause, in accordance with the standing instructions and procedures existing between the Depository and the Notes Custodian, the aggregate
principal amount of Notes represented by the Global Note to be increased by the aggregate principal amount of the Definitive Note to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a
beneficial interest in the Global Note equal to the principal amount of the Definitive Note so canceled. If no Global Notes are then outstanding and the Global Note has not been previously exchanged for certificated securities pursuant to
Section 2.6 of this Supplemental Indenture, the Company shall issue and the Trustee shall authenticate, upon receipt of a Company Order, a new Global Note in the appropriate principal amount. 

(c) Transfer and Exchange of Global Notes. 

(i) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in
accordance with this Supplemental Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Note shall deliver a written order
given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in such Global Note or another Global Note and such account shall be
credited in accordance with such order with a beneficial interest in the applicable 

  
 7 

 
Global Note and the account of the Person making the transfer shall be debited by an amount equal to the beneficial interest in the Global Note being transferred. Transfers by an owner of a
beneficial interest in a Rule 144A Global Note to a transferee who takes delivery of such interest through a Regulation S Global Note, whether before or after the expiration of the Restricted Period, shall be made only upon receipt by the Trustee of
a certification from the transferor to the effect that such transfer is being made in accordance with Rules 903 or 904 of Regulation S or (if available) Rule 144 under the Securities Act and that, if such transfer is being made prior to the
expiration of the Restricted Period, the interest transferred shall be held immediately thereafter through Euroclear or Clearstream. 

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

(iii) Notwithstanding any other provisions of this Supplemental Indenture (other than the provisions set forth in
Section 2.6 of this Supplemental Indenture), a Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by
the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. 
 (iv) In the event
that a Global Note is exchanged for Definitive Notes pursuant to Section 2.6 of this Supplemental Indenture prior to the consummation of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement with respect to such
Notes, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.5 (including the certification requirements set forth on the reverse of the Initial Notes intended
to ensure that such transfers comply with Rule 144, Rule 144A, Regulation S or such other applicable exemption from registration under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the
Company. 
 (d) Restrictions on Transfer of Regulation S Global Notes. 

(i) Prior to the expiration of the Restricted Period, interests in a Regulation S Global Note may only be held through
Euroclear or Clearstream. During the Restricted Period, beneficial ownership interests in a Regulation S Global Note may only be sold, pledged or transferred through Euroclear or Clearstream in accordance with the Applicable Procedures and only
(a) to the Company, (b) so long as such security is eligible for resale pursuant to Rule 144A, to a person whom the selling holder reasonably believes is a QIB that purchases for its own account or for the account of a QIB to whom notice
is given that the resale, pledge or transfer is being made in reliance on Rule 144A, 

  
 8 

 
(c) in an offshore transaction in accordance with Regulation S, (d) pursuant to an available exemption from registration under the Securities Act or (e) pursuant to an effective
registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any state of the United States. Prior to the expiration of the Restricted Period, transfers by an owner of a beneficial interest in a
Regulation S Global Note to a transferee who takes delivery of such interest through a Rule 144A Global Note shall be made only in accordance with the Applicable Procedures, pursuant to Rule 144 of the Securities Act or Rule 144A and upon receipt by
the Trustee of a written certification from the transferor of the beneficial interest in the form provided on the reverse of the Initial Note to the effect that such transfer is being made to a person whom the transferor reasonably believes is a QIB
within the meaning of Rule 144A in a transaction meeting the requirements of Rule 144A. Such written certification shall no longer be required after the expiration of the Restricted Period. In the case of a transfer of a beneficial interest in a
Regulation S Global Note for an interest in a Rule 144A Global Note, the transferee must, at the request of the Company, deliver an opinion of counsel reasonably acceptable to the Company stating that the proposed transfer is being made pursuant to
an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. 
 (ii) Upon the
expiration of the Restricted Period, beneficial ownership interests in a Regulation S Global Note shall be transferable in accordance with applicable law and the other terms of the Indenture.

 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE

UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES, TO OFFER, SELL
OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”) THAT IS ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH THE ISSUER OR ANY AFFILIATE OF THE
ISSUER WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR

LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES
FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING

TRANSFER PURSUANT TO CLAUSES (D) OR (E) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/ OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE
RESTRICTION TERMINATION DATE. 
 Each Note evidencing a Global Note offered and sold to QIBs pursuant to Rule 144A shall bear a legend in
substantially the following form:

THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 
 Each Definitive Note shall bear the
following additional legend: 
 IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH
CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS. 

(ii) Upon any sale or transfer of a Transfer Restricted Note that is a Definitive Note, the Security Registrar shall permit the
Holder thereof to exchange such Transfer Restricted Note for a Definitive Note that does not bear the legends set forth above and rescind any restriction on the transfer of such Transfer Restricted Note if the Holder certifies in writing to the
Security Registrar that its request for such exchange was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Initial Note). 

  
 10 

 (iii) After a transfer of any Initial Notes during the period of the
effectiveness of a Shelf Registration Statement with respect to such Initial Notes, as the case may be, all requirements pertaining to the Restricted Notes Legend on such Initial Notes shall cease to apply and the requirements that any such Initial
Notes be issued in global form shall continue to apply. 
 (iv) Upon the consummation of a Registered Exchange Offer with
respect to the Initial Notes pursuant to which Holders of such Initial Notes are offered Exchange Notes in exchange for their Initial Notes, all requirements pertaining to Initial Notes that Initial Notes be issued in global form shall continue to
apply, and Exchange Notes in global form without the Restricted Notes Legend shall be available to Holders that exchange such Initial Notes in such Registered Exchange Offer. 

(v) Upon a sale or transfer after the expiration of the Restricted Period of any Initial Note acquired pursuant to Regulation
S, all requirements that such Initial Note bear the Restricted Notes Legend shall cease to apply and the requirements requiring any such Initial Note be issued in global form shall continue to apply. 

(f) Cancellation or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been exchanged for
Definitive Notes, transferred, redeemed, repurchased or canceled, such Global Note shall be returned by the Depository to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial
interest in a Global Note is exchanged for Definitive Notes, transferred in exchange for an interest in another Global Note, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced and an
adjustment shall be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction.

similar governmental charge payable upon exchange or transfer pursuant to Sections 3.4, 9.6 or 11.7 of the Indenture). 
 (h) Prior to the
due presentation for registration of transfer of any Note, the Company, the Trustee, the Paying Agent or the Security Registrar may deem and treat the person in whose name a Note is registered as the absolute owner of such Note for the purpose of
receiving payment of principal of and interest on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the Trustee, the Paying Agent or the Security Registrar shall be affected by notice to
the contrary.

redeemed.

Global Note, a member of, or a participant in the Depository or any other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the
Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption or repurchase) or the payment of any amount, under or with respect to
such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to the registered Holders (which shall be the Depository or its nominee in the case of a Global
Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information

 2. Registration Under the Securities Act 

(a) To the extent not prohibited by any applicable law or applicable interpretations of the Staff, the Company shall use its commercially
reasonable efforts to (x) cause to be filed an Exchange Offer Registration Statement covering an offer to the Holders to exchange all the Registrable Securities for Exchange Notes and (y) have such Registration Statement become effective
on or before the Target Registration Date and, if requested by one or more Participating Broker-Dealers, remain effective until 180 days after the last Exchange Date for use by such Participating Broker-Dealers. The Company shall commence the
Exchange Offer for each series promptly after the Exchange Offer Registration Statement is declared effective by the SEC and use its commercially reasonable efforts to complete the Exchange Offer for such series not later than 60 days after such
effective date. 
 After the Exchange Offer Registration Statement has become effective, the Company shall commence the Exchange Offer for
each series by mailing the related Prospectus, appropriate letters of transmittal and other accompanying documents to each Holder stating, in addition to such other disclosures as are required by applicable law, substantially the following: 

(i) that such Exchange Offer is being made pursuant to this Agreement and that all Registrable Securities of such series
validly tendered and not properly withdrawn will be accepted for exchange; 
 (ii) the dates of acceptance for exchange
(which shall be a period of at least 20 Business Days from the date such notice is mailed) (each, an “Exchange Date”); 

(iii) that any Registrable Security not tendered will remain outstanding and continue to accrue interest but will not retain
any rights under this Agreement, except as otherwise specified herein; 
 (iv) that any Holder electing to have a Registrable
Security of a series exchanged pursuant to the Exchange Offer for such series will be required to (A) surrender such Registrable Security, together with the appropriate letters of transmittal, to the institution and at the address and in the
manner specified in the notice, or (B) effect such exchange otherwise in compliance with the applicable procedures of the depositary for such Registrable Security, in each case prior to the close of business on the last Exchange Date with
respect to such Exchange Offer; and 
 (v) that any Holder of Registrable Securities of a series will be entitled to withdraw
its election, not later than the close of business on the last Exchange Date with respect to the Exchange Offer for such series, by (A) sending to the institution and at the address specified in the notice, a facsimile transmission or letter
setting forth the 

  
 5 

 
name of such Holder, the principal amount of Registrable Securities delivered for exchange and a statement that such Holder is withdrawing its election to have such Registrable Securities
exchanged or (B) effecting such withdrawal in compliance with the applicable procedures of the depositary for the Registrable Securities. 

As a condition to participating in an Exchange Offer, a Holder will be required to represent to the Company that (1) any Exchange Notes
to be received by it will be acquired in the ordinary course of its business, (2) at the time of the commencement of such Exchange Offer it has no arrangement or understanding with any Person to participate in the distribution (within the
meaning of the Securities Act) of the Exchange Notes in violation of the provisions of the Securities Act, (3) it is not an “affiliate” (within the meaning of Rule 405 under the Securities Act) of the Company, (4) if such
Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Notes and (5) if such Holder is a broker-dealer that will receive Exchange
Notes for its own account in exchange for Registrable Securities that were acquired as a result of market-making or other trading activities, then such Holder will deliver a Prospectus (or, to the extent permitted by law, make available a Prospectus
to purchasers) in connection with any resale of such Exchange Notes. 
 As soon as practicable after the last Exchange Date with respect to
an Exchange Offer for Registrable Securities of a series, the Company shall: 
 (i) accept for exchange Registrable
Securities of such series or portions thereof validly tendered and not properly withdrawn pursuant to such Exchange Offer; and 

(ii) deliver, or cause to be delivered, to the Trustee for cancellation all Registrable Securities so accepted for exchange by
the Company and issue, and cause the Trustee to promptly authenticate and deliver to each Holder, Exchange Notes of such series equal in principal amount to the principal amount of the Registrable Securities of such series tendered by such Holder;
provided that if any of the Registrable Securities are in book-entry form, the Company shall, in cooperation with the Trustee, effect the exchange of Registrable Securities in accordance with applicable book-entry procedures. 

The Company shall use its commercially reasonable efforts to complete each Exchange Offer as provided above and shall comply with the
applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with each Exchange Offer. No Exchange Offer shall be subject to any conditions, other than that the Exchange Offer does not
violate any applicable law or applicable interpretations of the Staff and that no action or proceeding has been instituted or threatened in any court or by or before any governmental agency relating to the Exchange Offer which, in the Company’s
judgment, could reasonably be expected to impair the Company’s ability to proceed with the Exchange Offer. 
 (b) In the event that
(i) the Company determines that the Exchange Offer Registration provided for in Section 2(a) hereof is not available or the Exchange Offer for Registrable Securities of a series may not be completed as soon as practicable after the last
Exchange Date with respect to such Exchange Offer because it would violate any applicable law or applicable interpretations of the Staff, (ii) such Exchange Offer is not for any other reason 

  
 6 

 
completed by the Target Registration Date or (iii) prior to the last Exchange Date with respect to such Exchange Offer, the Company receives a written request (a “Shelf
Request”) from any Initial Purchaser representing that it holds Registrable Securities of the applicable series that are or were ineligible to be exchanged in such Exchange Offer, the Company shall use its commercially reasonable efforts to
cause to be filed as soon as practicable after such determination, date or Shelf Request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities of such series by the Holders thereof and to have
such Shelf Registration Statement become effective; provided that (a) no Holder will be entitled to have any Registrable Securities included in any Shelf Registration Statement, or entitled to use the Prospectus forming a part of such
Shelf Registration Statement, until such Holder shall have delivered a completed and signed Notice and Questionnaire and provided such other information regarding such Holder to the Company as is contemplated by Section 3(b) hereof and, if
necessary, the Shelf Registration Statement has been amended to reflect such information, and (b) the Company shall be under no obligation to file any such Shelf Registration Statement before they are obligated to file an Exchange Offer
Registration Statement pursuant to Section 2(a) hereof. 
 In the event that the Company is required to file a Shelf Registration
Statement pursuant to clause (iii) of the preceding sentence, the Company shall use its commercially reasonable efforts to file and have become effective both an Exchange Offer Registration Statement pursuant to Section 2(a) hereof with
respect to all Registrable Securities and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by the Initial
Purchasers after completion of the Exchange Offer. 
 The Company agrees to use its commercially reasonable efforts to keep the Shelf
Registration Statement continuously effective until the date on which the Notes covered thereby cease to be Registrable Securities (the “Shelf Effectiveness Period”). The Company further agrees to supplement or amend the Shelf
Registration Statement, the related Prospectus and any Free Writing Prospectus if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement or by the Securities
Act or by any other rules and regulations thereunder or if reasonably requested by a Participating Holder of Registrable Securities with respect to information relating to such Holder, and to use its commercially reasonable efforts to cause any such
amendment to become effective, if required, and such Shelf Registration Statement, Prospectus or Free Writing Prospectus, as the case may be, to become usable as soon as thereafter practicable. The Company agrees to furnish to the Participating
Holders copies of any such supplement or amendment promptly after its being used or filed with the SEC, as requested by the Participating Holders. 

(c) The Company shall pay all Registration Expenses in connection with any registration pursuant to Section 2(a) or Section 2(b)
hereof. Each Holder shall pay all underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration
Statement. 

  
 7 

 (d) An Exchange Offer Registration Statement pursuant to Section 2(a) hereof will not be
deemed to have become effective unless it has been declared effective by the SEC. A Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC or is
automatically effective upon filing with the SEC as provided by Rule 462 under the Securities Act. 
 If a Registration Default occurs with
respect to a series of Registrable Securities, the interest rate on the Registrable Securities of such series will be increased by (i) 0.25% per annum for the first 90-day period beginning on the day immediately following such Registration
Default and (ii) an additional 0.25% per annum with respect to each subsequent 90-day period, in each case until and including the date such Registration Default ends, up to a maximum increase of 1.00% per annum. A Registration
Default ends with respect to any Note when such Note ceases to be a Registrable Security or, if earlier, (1) in the case of a Registration Default under clause (i) or (ii) of the definition thereof, when the Exchange Offer for such
series is completed or when the Shelf Registration Statement covering such Registrable Securities becomes effective or (2) in the case of a Registration Default under clause (iii) or (iv) of the definition thereof, when the Shelf
Registration Statement again becomes effective or the Prospectus again becomes usable. If at any time more than one Registration Default has occurred and is continuing, then, until the next date that there is no Registration Default, the increase in
interest rate provided for by this paragraph shall apply as if there occurred a single Registration Default that begins on the date that the earliest such Registration Default occurred and ends on such next date that there is no Registration
Default. 
 Notwithstanding anything to the contrary in this Agreement, if the applicable Exchange Offer with respect to a series of
Registrable Securities is consummated, any Holder who was, at the time such Exchange Offer was pending and consummated, eligible to exchange, and did not validly tender, or withdrew, its Notes for Exchange Notes in such Exchange Offer will not be
entitled to receive any additional interest pursuant to the preceding paragraph, and such Notes will no longer constitute Registrable Securities hereunder. 

(e) The Company shall be entitled to suspend its obligation to file any amendment to a Shelf Registration Statement, furnish any supplement or
amendment to a Prospectus included in a Shelf Registration Statement or any Free Writing Prospectus, make any other filing with the SEC that would be incorporated by reference into a Shelf Registration Statement, cause a Shelf Registration Statement
to remain effective or the Prospectus or any Free Writing Prospectus usable or take any similar action (collectively, “Suspension Actions”) if there is a possible acquisition, disposition or business combination or other
transaction, business development or event involving the Company or its subsidiaries that may require disclosure in the Shelf Registration Statement or Prospectus and the Company determines that such disclosure is not in the best interest of the
Company and its stockholders or obtaining any financial statements relating to any such acquisition or business combination required to be included in the Shelf Registration Statement or Prospectus would be impracticable. Upon the occurrence of any
of the conditions described in the foregoing sentence, the Company shall give prompt notice of the delay or suspension (but not the basis thereof) to the Participating Holders. Upon the termination of such condition, the Company shall promptly
proceed with all Suspension Actions that were delayed or suspended and, if required, shall give prompt notice to the Participating Holders of the cessation of the delay or suspension (but not the basis thereof). 

  
 8 

 (f) Without limiting the remedies available to the Initial Purchasers and the Holders, the
Company acknowledges that any failure by the Company to comply with its obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no
adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may seek to specifically enforce the Company’s obligations
under Section 2(a) and Section 2(b) hereof. 
 3. Registration Procedures 

(a) In connection with its obligations pursuant to Section 2(a) and Section 2(b) hereof, the Company shall: 

(i) use its commercially reasonable efforts to prepare and file with the SEC a Registration Statement on the appropriate form

supplement thereto (other than any document that is deemed to amend or supplement such Prospectus, preliminary prospectus or Free Writing Prospectus because such document is incorporated by reference therein), as such Participating Holder, counsel
or Underwriter may reasonably request in writing in order to facilitate the sale or other disposition of the Registrable Securities thereunder; and, subject to Section 3(c) hereof, the Company consents to the use of such Prospectus,

  
 9

applicable law;

of such jurisdictions of the United States as any Participating Holder shall reasonably request in writing by the time the applicable Registration Statement becomes effective; cooperate with such Participating Holders in connection with any filings

Participating Holder; provided that the Company shall not be required to (1) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify,

Statement and the closing of any sale of Registrable Securities covered thereby, the representations and warranties of the Company contained in any underwriting agreement, securities sales agreement or other similar agreement, if any, relating to an
offering of such Registrable Securities cease to be true and correct in all material respects or if the Company receives any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any U.S.

the statements therein not misleading in any material respect and (5) of any determination by the Company that a post-effective amendment to a Registration Statement or any amendment or supplement to the Prospectus or any Free Writing
Prospectus would be appropriate; 

  
 10 

 (vii) notify counsel for the Initial Purchasers or, in the case of a Shelf

(xi) upon the occurrence of any event contemplated by Section 3(a)(vi)(4) hereof, prepare and file with the SEC a
supplement or post-effective amendment to the applicable Exchange Offer Registration Statement or Shelf Registration Statement or the related Prospectus or any Free Writing Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered (or, to the extent permitted by law, made available) to purchasers of the Registrable Securities, such Prospectus or Free Writing Prospectus, as the case may be, will not contain any untrue
statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Company shall notify the Participating Holders (in the case
of a Shelf Registration Statement) and the Initial Purchasers and any Participating Broker-Dealers known to the Company (in the case of an Exchange Offer Registration Statement) to suspend use of the Prospectus or any Free Writing Prospectus as
promptly as practicable after the occurrence of such an event, and such Participating Holders, such Participating Broker-Dealers and the Initial Purchasers, as applicable, hereby agree to suspend use of the Prospectus or any Free Writing Prospectus,
as the case may be, until the Company has amended or supplemented the Prospectus or the Free Writing Prospectus, as the case may be, to correct such misstatement or omission; 

  
 11 

 (xii) a reasonable time prior to the filing of any Registration Statement, any
Prospectus, any Free Writing Prospectus, any amendment to a Registration Statement or amendment or supplement to a Prospectus or a Free Writing Prospectus, provide copies of such document to the Representatives and their counsel (and, in the case of
a Shelf Registration Statement, to the Participating Holders and their counsel) and make such of the representatives of the Company as shall be reasonably requested by the Representatives or their counsel (and, in the case of a Shelf Registration
Statement, the Participating Holders or their counsel) available for discussion of such document; and the Company shall not, at any time after initial filing of a Registration Statement, use or file any Prospectus, any Free Writing Prospectus, any
amendment of or supplement to a Registration Statement or a Prospectus or a Free Writing Prospectus, of which the Representatives and their counsel (and, in the case of a Shelf Registration Statement, the Participating Holders and their counsel)
shall not have previously been advised and furnished a copy or to which the Representatives or their counsel (and, in the case of a Shelf Registration Statement, the Participating Holders or their counsel) shall reasonably object in writing within
two Business Days after receipt thereof; 
 (xiii) obtain a CUSIP number for all Exchange Notes of each series or Registrable
Securities of each series that are registered on a Shelf Registration Statement, as the case may be, not later than the initial effective date of a Registration Statement; 

(xiv) cause the Indenture to be qualified under the Trust Indenture Act in connection with the registration of the Exchange
Notes or Registrable Securities, as the case may be; cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the Trust Indenture Act;
and execute, cause the Trustee to execute, all documents as may be required to effect such changes and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner; 

(xv) in the case of a Shelf Registration, make available for inspection by a representative of the Participating Holders (an
“Inspector”), any Underwriters participating in any disposition pursuant to such Shelf Registration Statement, one firm of attorneys and one firm of accountants designated by a majority in aggregate principal amount of the
Registrable Securities held by the Participating Holders and one firm of attorneys and one firm of accountants designated by such Underwriters, at reasonable times and in a reasonable manner, all pertinent financial and other records, documents and
properties of the Company and its subsidiaries reasonably requested by any such Inspector, Underwriter, attorney or accountant, and cause the respective officers, directors and employees of the Company to supply all information reasonably requested
by any such Inspector, Underwriter, attorney or accountant in connection with a Shelf Registration Statement and customary due diligence related to the offering and sale of Registrable Securities thereunder, subject to such parties conducting such
investigation entering into confidentiality agreements as the Company may reasonably require and to any applicable privilege; 

  
 12 

 (xvi) in the case of a Shelf Registration, cause all Registrable Securities
covered thereby to be listed on any securities exchange or any automated quotation system on which similar senior unconvertible debt securities issued by the Company are then listed if requested by the Holders of a majority in principal amount of
the Registrable Securities covered by the Shelf Registration Statement, to the extent such Registrable Securities satisfy applicable listing requirements; 

(xvii) if reasonably requested by any Participating Holder, promptly include or incorporate by reference in a Prospectus
supplement or post-effective amendment such information with respect to such Participating Holder as such Participating Holder reasonably requests to be included therein, based upon a reasonable belief that such information is required to be
included therein or is necessary to make the information about such Participating Holder not misleading, and make all required filings of such Prospectus supplement or such post-effective amendment as soon as reasonably practicable after the Company
has received notification of the matters to be so included in such filing; and 
 (xviii) in the case of a Shelf
Registration, enter into such customary agreements and take all such other actions in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Securities covered by the Shelf Registration
Statement) in order to expedite or facilitate the disposition of such Registrable Securities including, but not limited to, an Underwritten Offering and in such connection, (1) provided that the Participating Holders’
representations and warranties are of the substance and scope as are customarily made by selling securityholders to underwriters in underwritten offerings, to the extent possible, make such representations and warranties to the Participating Holders
and any Underwriters of such Registrable Securities with respect to the business of the Company and its subsidiaries and the Registration Statement, Prospectus, any Free Writing Prospectus and documents incorporated by reference or deemed
incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and consistent with the applicable representations and warranties in the Purchase Agreement
and confirm the same if and when requested, (2) obtain opinions of counsel to the Company (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Participating Holders and such Underwriters and their
respective counsel) addressed to the Underwriter of Registrable Securities, covering the matters customarily covered in opinions requested in underwritten offerings and consistent with the opinions delivered pursuant to the Purchase Agreement,
provided that, if required by the Underwriter, counsel for the Participating Holders shall provide an opinion to the Underwriter covering the matters customarily covered in opinions requested from selling security holders by underwriters in
underwritten offerings, in connection with an Underwritten Offering (3) in connection with an Underwritten Offering, obtain “comfort” letters from the independent registered public accountants of the Company (and, if necessary, any
other registered public accountant of any subsidiary of the Company, or of any business acquired by the Company for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to the
Underwriter of Registrable Securities, such letters to be in customary form and covering matters of the 

  
 13 

 
type customarily covered in “comfort” letters in connection with underwritten offerings, including but not limited to financial information contained in any preliminary prospectus,
Prospectus or Free Writing Prospectus and (4) in connection with an Underwritten Offering, deliver such documents and certificates as may be reasonably requested by the Underwriters, and which are customarily delivered in underwritten
offerings, to evidence the continued validity of the representations and warranties made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement. 

(b) In the case of a Shelf Registration Statement, the Company may require, as a condition to including such Holder’s Registrable
Securities in such Shelf Registration Statement, each Holder of Registrable Securities to furnish to the Company a Notice and Questionnaire and such other information regarding such Holder and the proposed disposition by such Holder of such
Registrable Securities and other documentation necessary to effectuate the proposed disposition as the Company may from time to time reasonably request in writing and require such Holder to agree in writing to be bound by all provisions of this
Agreement applicable to such Holder. Each Holder of Registrable Securities as to which any Shelf Registration is being effected agrees to furnish promptly to the Company all information required to be disclosed so that the information previously
furnished to the Company by such Holder is not materially misleading and does not omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which
they were made. 
 (c) Each Participating Holder agrees that, upon receipt of any notice from the Company of the happening of any event of
the kind described in Section 3(a)(vi)(2) or Section 3(a)(vi)(4) hereof, such Participating Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Shelf Registration Statement until such Participating
Holder’s receipt of the copies of the supplemented or amended Prospectus and any Free Writing Prospectus contemplated by Section 3(a)(xi) hereof and, if so directed by the Company, such Participating Holder will deliver to the Company all
copies in its possession, other than permanent file copies then in such Participating Holder’s possession, of the Prospectus and any Free Writing Prospectus covering such Registrable Securities that is current at the time of receipt of such
notice. 
 (d) If the Company shall give any notice to suspend the disposition of Registrable Securities pursuant to a Registration
Statement, the Company shall extend the period during which such Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and
including the date when the Holders of such Registrable Securities shall have received copies of the supplemented or amended Prospectus or any Free Writing Prospectus necessary to resume such dispositions or notice that such amendment or supplement
is not necessary; provided, however, that no such extension shall be made in the case where such suspension is solely a result of the Company’s compliance with Section 3(b) or any other suspension at the request of a Holder.

  
 14 

 (e) The Participating Holders who desire to do so may sell such Registrable Securities in an
Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers (each an “Underwriter”) that will administer the offering will be selected by the Holders of a majority in
principal amount of the Registrable Securities included in such offering, subject in each case to consent by the Company (which shall not be unreasonably withheld or delayed so long as such bank or manager is internationally recognized as a
underwriter of debt securities offerings). 
 (f) No Holder of Registrable Securities may participate in any Underwritten Offering hereunder
unless such Holder (a) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements. 

4. Participation of Broker-Dealers in Exchange Offer 

(a) The Staff has taken the position that any broker-dealer that receives Exchange Notes for its own account in an Exchange Offer in exchange
for Notes that were acquired by such broker-dealer as a result of market-making or other trading activities (a “Participating Broker-Dealer”) may be deemed to be an “underwriter”
within the meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes. 

The Company understands that it is the Staff’s position that if the Prospectus contained in an Exchange Offer Registration Statement
includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Notes, without naming the Participating Broker-Dealers or
specifying the amount of Exchange Notes owned by them, such Prospectus may be delivered by Participating Broker-Dealers (or, to the extent permitted by law, made available to purchasers) to satisfy their prospectus delivery obligation under the
Securities Act in connection with resales of Exchange Notes for their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act. 

(b) In light of the above, and notwithstanding the other provisions of this Agreement, the Company agrees to amend or supplement the
Prospectus contained in the Exchange Offer Registration Statement for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to Section 3(d) hereof), if requested by one or more Participating
Broker-Dealers, in order to expedite or facilitate the disposition of any Exchange Notes by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4 above. The Company further agrees that Participating
Broker-Dealers shall be authorized to deliver such Prospectus (or, to the extent permitted by law, make available) during such period in connection with the resales contemplated by this Section 4. 

(c) The Initial Purchasers shall have no liability to the Company or any Holder with respect to any request that they may make pursuant to
Section 4(b) hereof. 

  
 15 

 5. Indemnification and Contribution 

(a) The Company agrees to indemnify and hold harmless each Initial Purchaser and each Holder, their respective directors, officers and
employees, each person, if any, who controls any Initial Purchaser or any Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Initial Purchaser within the
meaning of Rule 405 under the Securities Act, from and against any and all losses, claims, damages and liabilities, joint or several, to which such Initial Purchaser, Holder, director, officer, employee, controlling person or affiliate may become
subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any
Registration Statement, any Prospectus as amended or supplemented, any Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities
Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein in the light of the circumstances under which they were made not misleading, and will
reimburse each such Initial Purchaser, Holder, director, officer, employee, controlling person or affiliate for any legal or other expenses reasonably incurred by such Initial Purchaser, Holder, director, officer, employee, controlling person or
affiliate in connection with investigating or defending any such loss, damage, liability, action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Registration Statement, any Prospectus as amended or supplemented, any Free Writing
Prospectus or any Issuer Information in reliance upon and in conformity with information relating to any Initial Purchaser or any Holder furnished to the Company in writing by such Initial Purchaser through the Representatives or by such Holder
expressly for use therein. 
 (b) Each Holder will, severally and not jointly, indemnify and hold harmless the Company, the Initial
Purchasers and the other selling Holders, the directors, officers and employees of the Company and the Initial Purchasers, each Person, if any, who controls the Company, any Initial Purchaser and any other selling Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and each affiliate of any Initial Purchaser within the meaning of Rule 405 under the Securities Act against any losses, claims, damages or liabilities to which the
Company, or such Initial Purchaser, other selling Holder, director, officer, employee, controlling person or affiliate may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) that arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus as amended or supplemented or any Free Writing Prospectus, or arise out
of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Registration Statement, any Prospectus as amended or supplemented or any Free Writing Prospectus in reliance upon and in conformity with written information relating to such Holder furnished
to the Company by such Holder; and each Holder will reimburse the Company and such Initial Purchaser, other selling Holder, director, officer, employee, controlling person and affiliate in connection with investigating, or defending any such loss,
damage, liability, action or claim as such expenses are incurred, but only with reference to information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement, any Prospectus or
any Free Writing Prospectus. 

  
 16 

 (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of
notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the
omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party except to the extent such omission materially prejudices the indemnifying party. In case any such action shall be brought
against any indemnified party, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to
assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in
connection with the defense thereof other than reasonable costs of investigation. 
 (d) To the extent the indemnification provided for in
paragraph (a) or (b) of this Section 5 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein (or actions in respect thereof), then each indemnifying party
under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate
to reflect the relative benefits received by the Company from the offering of the Securities or Exchange Notes, on the one hand, and the Holders from receiving Securities or Exchange Notes registered under the Securities Act, on the other. If,
however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnifying party failed to give notice required under paragraph (c) of this Section 5, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company on the one hand and the Holders on the other in connection
with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and the Holders
on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on
the one hand or such Holder on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

(e) The Company and the Holders agree that it would not be just or equitable if contribution pursuant to this Section 5 were determined
by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations 

  
 17 

 
set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions
of this Section 5, no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Notes or Exchange Notes sold by such Holder exceeds the amount of any damages that such Holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 5 are several and not joint. 

(f) The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be
available to any Indemnified Person at law or in equity. 
 (g) The indemnity and contribution provisions contained in this Section 5
shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any Holder, any Person controlling any Initial Purchaser or
any Holder or any affiliate of any Initial Purchaser, or by or on behalf of the Company, its officers or directors or any Person controlling the Company, (iii) acceptance of any of the Exchange Notes and (iv) any sale of Registrable
Securities pursuant to a Shelf Registration Statement. 
 6. General 

(a) No Inconsistent Agreements. The Company represents, warrants and agrees that it has not entered into, or on or after the date of
this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. 

(b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified
or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Company has obtained the written consent of Holders of at least a majority in aggregate principal amount of the outstanding Registrable
Securities affected by such amendment, modification, supplement, waiver or consent; provided that no amendment, modification, supplement, waiver or consent to any departure from the provisions of Section 5 hereof shall be effective as
against any Holder of Registrable Securities unless consented to in writing by such Holder. Any amendments, modifications, supplements, waivers or consents pursuant to this Section 6(b) shall be by a writing executed by each of the parties
hereto. Each Holder of Registrable Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant
to this Section 6(b), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder. Each Holder may waive compliance
with respect to any obligation of the Company under this Agreement as it may apply or be enforced by such particular Holder. 

  
 18 

 (c) Notices. All notices and other communications provided for or permitted hereunder
shall be made in writing by hand-delivery, registered first-class mail, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder to the Company by means of a notice given in
accordance with the provisions of this Section 6(c), which address initially is, with respect to the Initial Purchasers, the address set forth in the Purchase Agreement; (ii) if to the Company, initially at the address(es) set forth in the
Purchase Agreement and thereafter at such other address(es), notice of which is given in accordance with the provisions of this Section 6(c); and (iii) to such other persons at their respective addresses as provided in the Purchase
Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c). All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if
personally delivered; three Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged, if telecopied; and on the next Business Day if timely delivered to an air courier guaranteeing overnight delivery.

 (d) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and
transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of
Registrable Securities in violation of the terms of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities
shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement
and such Person shall be entitled to receive the benefits hereof. The Initial Purchasers (in their capacity as Initial Purchasers) shall have no liability or obligation to the Company with respect to any failure by a Holder to comply with, or any
breach by any Holder of, any of the obligations of such Holder under this Agreement. 
 (e) Third Party Beneficiaries. Each Holder
shall be a third party beneficiary to the agreements made hereunder between the Company, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such
enforcement necessary or advisable to protect its rights or the rights of other Holders hereunder. 
 (f) Counterparts. This
Agreement may be executed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been
signed by each of the parties and delivered (by telecopy, electronic delivery or otherwise) to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format”
(“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature. 

  
 19 

 (g) Headings. The headings in this Agreement are for convenience of reference only, are
not a part of this Agreement and shall not limit or otherwise affect the meaning hereof. 
 (h) Governing Law. This Agreement, and
any claim, controversy or dispute arising under or related to this Agreement, shall be governed by and construed in accordance with the laws of the State of New York. 

(i) Entire Agreement; Severability. This Agreement contains the entire agreement between the parties relating to the subject matter
hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable or
against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated. The Company and the Initial Purchasers shall
endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, void or unenforceable provisions.
