successors and assigns under the Indenture being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided, however, that if a
Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period
that occurs after the date on which such Registration Default occurs up to an aggregate maximum additional interest rate of 1.00% per annum) from and including the date on which any such Registration Default shall occur to but excluding the
date on which all Registration Defaults have been cured. The Company will pay interest semiannually on June 1 and December 1 of each year, commencing
DecemberJune 1, 20162017. Interest on the Securities will accrue from the most
recent date to which interest has been paid or, if no interest has been paid, from June 7December 1, 2016. Interest will be computed on the basis of a 360-day year of
twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this Security plus 1.0% per annum, and it will pay interest on overdue installments of interest at the same
rate to the extent lawful. 
  

	2.	Method of Payment

private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depository. The Company

will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating
such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

banking corporation (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly

Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. 

 

	10.	Persons Deemed Owners 

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

	11.	Unclaimed Money 

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

	12.	Discharge and Defeasance 

 Subject to certain conditions, the Company at any time shall
be entitled to terminate some or all of its and the Subsidiary Guarantors’ obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and
interest on the Securities to redemption or maturity, as the case may be. 
  

	13.	Amendment; Waiver 

 Subject to certain exceptions set forth in the Indenture,
(a) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any provision may be waived with
the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company, the Subsidiary Guarantors and the Trustee
shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add Guarantees with respect to the Securities, including Subsidiary Guarantees, or to add additional covenants or surrender rights and powers conferred on the Company or the Subsidiary Guarantors or to make any change
that does not adversely affect the rights of any Holder, or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA, or to conform the text of the Indenture, the Securities or any Subsidiary
Guarantee to any provision of the “Description of the notes” in the Offering Memorandum to the extent that such provision in the “Description of the notes” was intended to be a verbatim recitation of a provision of the Indenture,
the Securities or such Subsidiary Guarantee, to make amendments to provisions of the Indenture relating to the transfer and legending of the Securities, or to provide for the issuance of Additional Securities. 

 

	14.	Defaults and Remedies 

 Under the Indenture, Events of Default include: (a) default
for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon redemption, upon acceleration or otherwise, or failure by the Company to redeem or purchase Securities when
required; (c) failure by the Company or any Subsidiary Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (d) certain accelerations (including failure to pay
within any grace period after final maturity) of other Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $30,000,000; (e) certain events of bankruptcy or
insolvency with respect to the Company and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $30,000,000; and (g) certain defaults with respect to Subsidiary Guarantees. If an Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default
that will result in the Securities becoming due and payable immediately upon the occurrence of such Events of Default. 

 Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The
Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee
in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders. 

 

	15.	Trustee Dealings with the Company 

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

	16.	No Recourse Against Others 

 A director, officer, employee or stockholder, as such, of
the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities or the Indenture or for any claim based on, in respect of, or by reason of such obligations or
their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

 

	17.	Authentication 

 This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security. 
  

	18.	Abbreviations

	19.	CUSIP Numbers 

 Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

	20.	Holders’ Compliance with Registration Rights Agreement

Securities for Exchange Securities and (y) have such Registration Statement become and remain effective for use by one or more Participating Broker-Dealers until the earlier of (i) 180 days after the last Exchange Date (as such period may

Exchange Offer has been completed. The Company and the Guarantors shall commence the Exchange Offer promptly after the Exchange Offer Registration Statement is declared effective by the SEC and

 The Company
and the Guarantors shall commence the Exchange Offer 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 the Exchange Offer is being made pursuant to this Agreement and that all Registrable Securities 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 (or longer if required by applicable law)) (the “Exchange Dates”);

  

	 	(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 exchanged pursuant to the Exchange Offer 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; and 

  

	 	(v)	that any Holder will be entitled to withdraw its election, not later than the close of business on the last Exchange Date, by (A) sending to the institution and at the address specified in the notice, a telegram,
facsimile transmission or letter setting forth the 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 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 the Exchange Offer, a Holder will be required to represent to the Company and the Guarantors that
(1) any Exchange Securities to be received by it will be acquired in the ordinary course of its business, (2) at the time of the commencement of the 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 Securities 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 or any Guarantor and (4) if such Holder is a broker-dealer that will receive Exchange Securities 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 Securities. 

 As soon as practicable after the last Exchange Date, the Company and the Guarantors shall: 

 

	 	(I)	accept for exchange Registrable Securities or portions thereof validly tendered and not properly withdrawn pursuant to the Exchange Offer; and 

 

	 	(II)	deliver, or cause to be delivered, to the Trustee for cancellation all Registrable Securities or portions thereof so accepted for exchange by the Company and issue, and cause the Trustee to promptly authenticate and
deliver to each Holder, Exchange Securities equal in principal amount to the principal amount of the Registrable Securities tendered by such Holder. 

The Company and the Guarantors shall use their commercially reasonable efforts to complete the 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 the Exchange Offer. The Exchange Offer shall not be subject to any conditions, other than that the Exchange
Offer does not violate any applicable law or applicable interpretations of the Staff. 
 For the avoidance of doubt, notwithstanding any
provision of this Section 2(a) purporting to require physical mailing, delivery or acceptance of any document or instrument, the Company and the Guarantors may conduct the Exchange Offer exclusively through the automated tender offer program of
the Depository Trust Company or any successor or similar system permitting electronic transmittal, tender and acceptance of documents and instruments; provided that this provision shall apply only to Registrable Securities held in the form of
beneficial interests in a global note deposited with (or held by a custodian for) the Depository Trust Company. 
 (b) In the event that
(i) the Company and the Guarantors determine that the Exchange Offer Registration provided for in Section 2(a) hereof is not available or the Exchange Offer may not be completed as soon as practicable after the last Exchange Date because
it would violate any applicable law or applicable interpretations of the Staff, (ii) the Exchange Offer is not for any other reason completed by the Target Registration Date or (iii) upon receipt of a written request (a “Shelf
Request”) from J.P. Morgan representing that it holds Registrable Securities that are or were ineligible to be exchanged in the Exchange Offer, the Company and the Guarantors shall use their commercially reasonable efforts to cause to be
filed as soon as practicable after such determination date, Target Registration Date or Shelf Request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof and to have
such Shelf Registration Statement become effective; provided that 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. 

In the event that the Company and the Guarantors are required to file a Shelf Registration Statement pursuant to clause (iii) of the
preceding sentence, the Company and the Guarantors shall use their 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 J.P. Morgan after completion of the
Exchange Offer. 

 The Company and the Guarantors agree to use their commercially reasonable efforts to keep the
Shelf Registration Statement continuously effective until the earlier of (i) one year following the date the Shelf Registration Statement is declared effective and (ii) Securities cease to be Registrable Securities (the “Shelf
Effectiveness Period”). The Company and the Guarantors further agree 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 and the Guarantors for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder or if reasonably requested by a Holder of Registrable
Securities with respect to information relating to such Holder and to use their commercially reasonable efforts to cause any such amendment to become effective, if required, and to cause such Shelf Registration Statement, Prospectus or Free Writing
Prospectus, as the case may be, to become usable as soon as thereafter practicable. The Company and the Guarantors agree to furnish to the Participating Holders copies of any such supplement or amendment promptly after its being used or filed with
the SEC. 
 (c) The Company and the Guarantors 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. 
 (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,
the interest rate on the Registrable Securities 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 when the Securities cease to be Registrable Securities
or, if earlier, (1) in the case of a Registration Default under clause (i) of the definition thereof, when the Exchange Offer is completed, (2) in the case of a Registration Default under clause (ii) or clause (iii) of the
definition thereof, when the Shelf Registration Statement becomes effective or (3) in the case of a Registration Default under clause (iv) or clause (v) 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 on which there is no Registration Default. 

 (e) Without limiting the remedies available to J.P. Morgan and the Holders, the Company and the
Guarantors acknowledge that any failure by the Company or the Guarantors to comply with their obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to J.P. Morgan 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, J.P. Morgan or any Holder may obtain such relief as may be required to specifically enforce the
Company’s and the Guarantors’ obligations under Section 2(a) and Section 2(b) hereof. The provisions for liquidated damages set forth in Section 2(d) above shall be the only monetary remedy available to Holders under this
Agreement. 
 3. Registration Procedures. (a) In connection with their obligations pursuant to Section 2(a) and
Section 2(b) hereof, the Company and the Guarantors shall promptly: 
 (i) prepare and file with the SEC a Registration Statement on
the appropriate form under the Securities Act, which form (A) shall be selected by the Company and the Guarantors, (B) shall, in the case of a Shelf Registration, be available for the sale of the Registrable Securities by the Holders
thereof and (C) shall comply as to form in all material respects with the requirements of the applicable form and include (or incorporate by reference) all financial statements required by the SEC to be filed therewith; and use their
commercially reasonable efforts to cause such Registration Statement to become effective and remain effective for the applicable period in accordance with Section 2 hereof; 

(ii) prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep
such Registration Statement effective for the applicable period in accordance with Section 2 hereof and cause each Prospectus to be supplemented by any required prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424
under the Securities Act; and keep each Prospectus current during the period described in Section 4(a)(3) of and Rule 174 under the Securities Act that is applicable to transactions by brokers or dealers with respect to the Registrable
Securities or Exchange Securities; 
 (iii) to the extent any Free Writing Prospectus is used, file with the SEC any Free Writing Prospectus
that is required to be filed by the Company or the Guarantors with the SEC in accordance with the Securities Act and to retain (in accordance with the requirements of the Securities Act) any Free Writing Prospectus not required to be filed; 

(iv) in the case of a Shelf Registration, furnish to each Participating Holder, to counsel for J.P. Morgan, to counsel for such Participating
Holders and to each Underwriter of an Underwritten Offering of Registrable Securities, if any, without charge, as many copies of each Prospectus, preliminary prospectus or Free Writing Prospectus, and any amendment or supplement thereto, as such
Participating Holder, counsel or Underwriter may reasonably request in order to facilitate the sale or other disposition of the Registrable Securities thereunder; and, subject to Section 3(c) hereof, the Company and the Guarantors consent to
the use of such Prospectus, preliminary prospectus or such Free Writing Prospectus and any amendment or supplement thereto in accordance with applicable law by each of the Participating Holders and any such Underwriters in connection with the
offering and sale of the Registrable Securities covered by, and in the manner described in, such Prospectus, preliminary prospectus or such Free Writing Prospectus or any amendment or supplement thereto in accordance with applicable law; 

 (v) use their commercially reasonable efforts to register or qualify the Registrable Securities
under all applicable state securities or blue sky laws of such jurisdictions 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 required to be made with FINRA; and do any and all other acts and things that may be reasonably necessary or advisable to enable each Participating Holder to complete the disposition in each such jurisdiction
of the Registrable Securities owned by such Participating Holder; provided that neither the Company nor any Guarantor shall 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, (2) file any general consent to service of process in any such jurisdiction or (3) subject itself to taxation in any such jurisdiction if it is not so subject; 

(vi) notify counsel for J.P. Morgan and, in the case of a Shelf Registration, notify each Participating Holder and counsel for such
Participating Holders promptly after becoming aware and, if requested by any such Participating Holder or its counsel, thereafter confirm such notification in writing (1) when a Registration Statement has become effective, when any
post-effective amendment thereto has been filed and becomes effective, when any Free Writing Prospectus has been filed or any amendment or supplement to the Prospectus or any Free Writing Prospectus has been filed, (2) of any request by the SEC
or any state securities authority for amendments and supplements to a Registration Statement, Prospectus or any Free Writing Prospectus or for additional information after the Registration Statement has become effective, (3) of the issuance by
the SEC or any state securities authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose, including the receipt by the Company of any notice of objection of the SEC to
the use of a Shelf Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act, (4) if, between the applicable effective date of a Shelf Registration Statement and the closing of any sale
of Registrable Securities covered thereby, the representations and warranties of the Company or any Guarantor 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 or any Guarantor receives any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction
or the initiation of any proceeding for such purpose, (5) of the happening of any event during the period a Registration Statement is effective that makes any statement made in such Registration Statement or the related Prospectus or any Free
Writing Prospectus untrue in any material respect or that requires the making of any changes in such Registration Statement or Prospectus or any Free Writing Prospectus in order to make the statements therein not misleading (in the case of the
Prospectus, in the light of the circumstances under which they were made) and (6) of any determination by the Company or any Guarantor 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; 
 (vii) use their commercially reasonable efforts to obtain the withdrawal of any
order suspending the effectiveness of a Registration Statement or, in the case of a Shelf Registration, the resolution of any objection of the SEC pursuant to Rule 401(g)(2) under the Securities Act, including by filing an amendment to such
Registration Statement on the proper form, as promptly as practicable and provide prompt notice to each Holder or Participating Holder of the withdrawal of any such order or such resolution; 

 (viii) in the case of a Shelf Registration, furnish to each Participating Holder, without charge,
at least one conformed copy of each Registration Statement and any post-effective amendment thereto (without any documents incorporated therein by reference or exhibits thereto, unless requested in writing); 

(ix) in the case of a Shelf Registration, cooperate with the Participating Holders to facilitate the timely preparation and delivery of
certificates representing Registrable Securities to be sold and not bearing any restrictive legends and enable such Registrable Securities to be issued in such denominations and registered in such names (consistent with the provisions of the
Indenture) as such Participating Holders may reasonably request at least one Business Day prior to the closing of any sale of Registrable Securities; 

(x) upon the occurrence of any event contemplated by Section 3(a)(vi)(5) hereof, use their commercially reasonable efforts to 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 and the Guarantors shall notify
the Participating Holders (in the case of a Shelf Registration Statement) and J.P. Morgan 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 J.P. Morgan, as applicable, hereby agree to suspend use of the Prospectus or any Free
Writing Prospectus, as the case may be, until the Company and the Guarantors have amended or supplemented the Prospectus or any such Free Writing Prospectus, as the case may be, to correct such misstatement or omission; 

(xi) 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 or of any document that is to be incorporated by reference into a Registration Statement, a Prospectus or a Free Writing Prospectus after initial filing
of a Registration Statement, provide copies of such document to the J.P. Morgan and its 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
and the Guarantors as shall be reasonably requested by J.P. Morgan or its 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 and the
Guarantors 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, or
any document that is to be incorporated by reference into a Registration Statement, a Prospectus or a Free Writing Prospectus, of which J.P. Morgan and its 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 J.P. Morgan or its counsel (and, in the case of a Shelf Registration Statement, the Participating Holders or their counsel) shall reasonably object in writing
within a reasonable amount of time after the receipt thereof; 

 (xii) (A) obtain a CUSIP number for all Exchange Securities or Registrable Securities, as the
case may be, not later than the initial effective date of a Registration Statement; and (B) use commercially reasonable efforts to obtain the same CUSIP number for all Exchange Securities as that of the June 2016 Exchange Securities exchanged
pursuant to the June 2016 Exchange Offer; 
 (xiii) cause the Indenture to be qualified under the Trust Indenture Act in connection with the
registration of the Exchange Securities 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, and use their commercially reasonable efforts to 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; 
 (xiv) in the case of a Shelf Registration, make available for inspection
by a representative of the Participating Holders (an “Inspector”), any Underwriter participating in any disposition pursuant to such Shelf Registration Statement, one firm of attorneys and one firm of accountants designated by
Participating Holders holding a majority in aggregate principal amount of the Securities and any attorneys and accountants designated by such Underwriter, at reasonable times and in a reasonable manner, all pertinent financial and other records,
documents and properties of the Company and its subsidiaries, and cause the respective officers, directors and employees of the Company and the Guarantors to supply all information reasonably requested by any such Inspector, Underwriter, attorney or
accountant in connection with a Shelf Registration Statement; provided that if any such information is identified by the Company or any Guarantor as being confidential or proprietary, each Person receiving such information shall take such
actions as are reasonably necessary to protect the confidentiality of such information to the extent such action is otherwise not inconsistent with, an impairment of or in derogation of the rights and interests of any Inspector, Holder or
Underwriter; 
 (xv) if reasonably requested by any Participating Holder, promptly include 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 and make all required filings of such Prospectus supplement or such post-effective amendment as soon as the
Company has received notification of the matters to be so included in such filing; 
 (xvi) in the case of a Shelf Registration, enter into
such customary agreements and take all such other actions necessary or appropriate in connection therewith (including those requested by the Holders of a majority in aggregate 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 connection therewith, (1) 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 confirm the same if and when requested
by any Participating Holder or Underwriter, (2) obtain opinions of counsel to the Company and the Guarantors (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Participating Holders and the
Underwriters and their respective counsel) 

 
addressed to each Participating Holder and each Underwriter of Registrable Securities, covering the matters customarily covered in opinions requested in underwritten offerings, (3) obtain
“comfort” letters from the independent registered public accountants of the Company and the Guarantors (and, if necessary, any other registered public accountant of any subsidiary of the Company or any Guarantor, or of any business
acquired by the Company or any Guarantor for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each Participating Holder (to the extent permitted by applicable professional
standards) and each Underwriter of Registrable Securities, in each case, such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings of debt
securities similar to the Securities, including, but not limited to, financial information contained in any preliminary prospectus, Prospectus or Free Writing Prospectus and (4) deliver such documents and certificates as may be reasonably
requested by the Holders of a majority in aggregate principal amount of the Registrable Securities being sold or any Underwriter and which are customarily delivered in underwritten offerings of debt securities similar to the Securities, to evidence
the continued validity of the representations and warranties of the Company and the Guarantors made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement; and 

(xvii) so long as any Registrable Securities remain outstanding, cause each Additional Guarantor, upon becoming a Guarantor, to execute a
counterpart to this Agreement in the form attached hereto as Annex A and to deliver such counterpart, together with an opinion of counsel as to the enforceability thereof against such entity, to J.P. Morgan no later than five Business Days following
the execution thereof. 
 (b) In the case of a Shelf Registration Statement, the Company may require 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 as the Company and the Guarantors may from time to time reasonably
request in writing; provided that if such Holder fails to provide the requested information within 20 Business Days, the Company may exclude such Holder’s Registrable Securities from such Shelf Registration Statement until a period of
time after the information is provided as is reasonably necessary to permit the Company to review such information and, if applicable, amend or supplement such Shelf Registration Statement. 

(c) Each Participating Holder agrees that, upon receipt of any notice from the Company and the Guarantors of the happening of any event of the
kind described in Section 3(a)(vi)(3) or Section 3(a)(vi)(5) 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)(x) hereof and, if so directed by the Company and the Guarantors, such Participating Holder will deliver
to the Company and the Guarantors 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 and the Guarantors shall give any notice to suspend the disposition of
Registrable Securities pursuant to a Registration Statement, the Company and the Guarantors 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 on which 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. The Company and the Guarantors may give any such notice only twice during any 365-day
period and any such suspensions shall not exceed 30 days for each suspension and there shall not be more than two suspensions in effect during any 365-day period. 

(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 aggregate principal amount of the Registrable
Securities included in such Underwritten Offering. 
 4. Participation of Broker-Dealers in Exchange Offer. (a) The Company has
been advised that the Staff has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or
other trading activities (each, 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 Securities. 
 The Company and the Guarantors have been advised that it is the Staff’s
position that if the Prospectus contained in the 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 Securities
without naming the Participating Broker-Dealers or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered or, to the extent permitted by law, made available, by Participating Broker-Dealers to purchasers to
satisfy such Participating Broker-Dealers’ prospectus delivery obligation under the Securities Act in connection with resales of Exchange Securities 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 and the Guarantors
agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement for a period ending on the earlier of (i) 180 days after the last Exchange Date (as such period may be extended pursuant to Section 3(d)
hereof) and (ii) when all Participating Broker-Dealers have sold all of their Exchange Securities (if any) and the Exchange Offer has been completed, in order to expedite or facilitate the disposition of any Exchange Securities by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Company and the Guarantors further agree that Participating Broker-Dealers shall be authorized to deliver or, to the extent permitted by law, make
available such Prospectus during such period in connection with the resales contemplated by this Section 4. 
 (c) J.P. Morgan shall
have no liability to the Company, any Guarantor or any Holder with respect to any request that they may make pursuant to Section 4(b) hereof. 

5. Indemnification and Contribution. (a) The Company and each Guarantor, jointly and severally, agree to indemnify and hold
harmless J.P. Morgan and each Holder, their 

 
respective “affiliates” (within the meaning of Rule 405 under the Securities Act), directors and officers and each Person, if any, who controls J.P. Morgan or any Holder within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in
connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (1) any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (2) any untrue statement or
alleged untrue statement of a material fact contained in any Prospectus, 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 any 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, in each case, except insofar as
such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to J.P. Morgan or information
relating to any Holder furnished to the Company in writing through J.P. Morgan or any selling Holder, respectively, expressly for use therein. In connection with any Underwritten Offering permitted by Section 3 hereof, the Company and the
Guarantors, jointly and severally, will also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their respective “affiliates” (within the meaning of
Rule 405 under the Securities Act) and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in
connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information. 
 (b) Each Holder
agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors, J.P. Morgan and the other selling Holders, the directors of the Company and the Guarantors, each officer of the Company and the Guarantors who signed the
Registration Statement and each Person, if any, who controls the Company, the Guarantors, J.P. Morgan and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent
as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with any information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement, any Prospectus and any Free Writing Prospectus. 

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted
against any Person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such indemnification
may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to
the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any
liability that it may have to an Indemnified Person 

 
otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person
thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 5 that the Indemnifying Person may
designate in such proceeding and shall pay the reasonable fees and expenses of such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person
shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses
available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding
or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are
incurred. Any such separate firm (x) for J.P. Morgan, its “affiliates” (within the meaning of Rule 405 under the Securities Act), directors and officers and any control Persons of J.P. Morgan shall be designated in writing by J.P.
Morgan, (y) for any Holder, its directors and officers and any control Persons of such Holder shall be designated in writing by the Majority Holders and (z) in all other cases shall be designated in writing by the Company. The Indemnifying
Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified
Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and
substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by
or on behalf of any Indemnified Person. 
 (d) If the indemnification provided for in paragraphs (a) and (b) above is unavailable
to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute
to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors from the
offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand, or (ii) if the allocation provided by clause
(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Holders

 
on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative
fault of the Company and the Guarantors 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 and the Guarantors or by the Holders, as applicable, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission. 
 (e) The Company, the Guarantors and the Holders each agree that it would not be just and 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 set forth above,
any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the
amount by which the total price at which the Securities or Exchange Securities 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.
