 ARTICLE TWO 

THE NOTES 
 Pursuant to Article
Two of the Base Indenture, the provisions of this Article Two and the other provisions of this Supplemental Indenture establish the form and terms of the Notes and the Guarantees under this Supplemental Indenture. 

SECTION 2.01 Form and Dating. 
 The
Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. The Issuer shall approve the form
of the Notes and any notation, legend or endorsement on them. Each Note shall be dated the date of its issuance and show the date of its authentication. 

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent
applicable, the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 

Notes offered and sold in reliance on Rule 144A shall be issued initially in the form of a single permanent global Note in registered form,

SECTION 2.02 Execution, Authentication and Denomination; Additional Notes. 

One Officer of the Issuer (who shall have been duly authorized by all requisite corporate actions) shall sign the Notes on behalf of the Issuer
by manual or facsimile signature. 
 If an Officer whose signature is on a Note was an Officer at the time of such execution but no longer
holds that office at the time the Trustee authenticates such Note, such Note shall nevertheless be valid. 
 A Note shall not be valid until
an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 

The Trustee shall authenticate (i) on the Issue Date, Notes for original issue in an aggregate principal amount not to exceed
$425,000,000 (the “Initial Notes”), and (ii) so long as not otherwise prohibited by the terms of this Indenture, including Section 4.07, additional Notes in an unlimited principal amount (the “Additional
Notes”), in each case upon a written order of the Issuer in the form of a certificate of an Officer of the Issuer (an “Authentication Order”). Each such Authentication Order shall specify the amount of Notes to be
authenticated and the date on which the Notes are to be authenticated, whether the Notes are to be Initial Notes or Additional Notes and whether the Notes are to be issued as certificated Notes or Global Notes and such other information as the
Trustee may reasonably request. In addition, with respect to authentication pursuant to clause (ii) of the first sentence of this paragraph, such Authentication Order from the Issuer (i) shall certify that such issuance is in compliance
with Section 4.07 and is otherwise permitted by the terms of the Indenture and (ii) shall be accompanied by an Opinion of Counsel of the Issuer in a form reasonably satisfactory to the Trustee. 

Notes may be issued in one or more series (with all of the Notes of any one series to be substantially identical except as to denomination),
and Additional Notes may have an issue date, issue price, aggregate principal amount or first interest payment date different from those of the 

  
 -37- 








 
Initial Notes or any other Additional Notes. Any Additional Notes that are not fungible with the Initial Notes or any other Additional Notes for United States federal income tax purposes shall
constitute a separate issue and shall carry a separate “CUSIP” or “ISIN” number. Notwithstanding the foregoing, all Notes issued under this Indenture shall be treated as a single class for all purposes under this Indenture,
including for purposes of voting with respect to consents, waivers and amendments regarding this Indenture or the Notes and redemptions of and offers to purchase the Notes. The Notes shall bear any legend required by applicable law. 

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate Notes. Unless otherwise provided in the
appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an
Agent to deal with the Issuer and Affiliates of the Issuer. The Trustee shall have the right to decline to authenticate and deliver any Notes under this Indenture if the Trustee, being advised by counsel, determines that such action may not lawfully
be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability. 
 The Notes shall
be issuable in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000. 
 SECTION 2.03 Registrar and
Paying Agent. 
 The Issuer shall maintain or cause to be maintained an office or agency in the Borough of Manhattan, The City of New
York, New York where (a) Notes may be presented or surrendered for registration of transfer or exchange (“Registrar”) and (b) Notes may, subject to Section 2 of the Notes, be presented or surrendered for payment
(“Paying Agent”). The Issuer may act as Registrar or Paying Agent, except that for the purposes of Articles Three and Eight and Section 4.06 and Section 4.10, neither the Issuer nor any Affiliate of the Issuer shall act as
Paying Agent. The Registrar shall keep a register of the Notes and of their transfer and exchange. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer hereby
appoints the Trustee as the initial Registrar and Paying Agent for the Notes and the Trustee hereby agrees to so act. The Issuer will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each
Registrar and Paying Agent. If at any time the Issuer shall fail to maintain any such required Registrar and Paying Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices and demands may
be made or served at the Corporate Trust Office of the Trustee, and the Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands and the Trustee hereby agrees to so act. 

The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the
provisions of this Indenture that relate to such Agent. 
 The Issuer may also from time to time designate one or more co-registrars or
additional paying agents and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligations to maintain a Registrar and Paying Agent
in the place so specified above for such purposes. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address of any such co-registrar or additional paying agent. 

  
 -38- 








 Notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be
served to the Issuer at its address set forth in Section 12.02. 
 SECTION 2.04 Paying Agent to Hold Assets in Trust. 

The Trustee as Paying Agent shall, and the Issuer shall require each Paying Agent other than the Trustee or the Issuer or any Subsidiary to
agree in writing that it shall, subject to Article Ten and Section 11.02, hold in trust for the benefit of Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, or interest on, the Notes (whether such
assets have been distributed to it by the Issuer or any other obligor on the Notes), and shall notify the Trustee of any Default by the Issuer (or any other obligor on the Notes) in making any such payment. The Issuer at any time may require a
Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed, and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to
distribute all assets held by it to the Trustee and to account for any assets distributed. Upon distribution to the Trustee of all assets that shall have been delivered by the Issuer to the Paying Agent, the Paying Agent shall have no further
liability for such assets. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders of the Notes all money held by it as Paying Agent. 

SECTION 2.05 Holder Lists. 
 The
Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of the Notes and shall otherwise comply with Trust Indenture Act § 312(a). If the Trustee is not
the Registrar, the Issuer shall furnish to the Trustee at least two (2) Business Days prior to each Interest Payment Date and at such other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may
reasonably require, of the names and addresses of Holders, which list may be conclusively relied upon by the Trustee. 
 SECTION 2.06 Transfer and
Exchange. 
 Subject to Sections 2.15 and 2.16, when Notes are presented to the Registrar with a request to register the transfer of such
Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met;
provided, however, that the Notes surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof
or his or her attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Notes at the Registrar’s request. No service charge shall be made for any
registration of transfer or exchange (except as otherwise expressly permitted herein), but the Issuer or Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other
than any such transfer tax or similar governmental charge payable upon exchanges pursuant to Section 2.10, 3.06 or 9.06). 

  
 -39- 








 Without the prior written consent of the Issuer, the Registrar shall not be required to register
the transfer of or exchange of any Note (i) during the period beginning at the opening of business fifteen (15) days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing,
(ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Note being redeemed in part, and (iii) beginning at the opening of business on any Record Date and ending on the close of
business on the related Interest Payment Date. 
 Any Holder of a beneficial interest in a Global Note shall, by acceptance of such
beneficial interest, agree that transfers of beneficial interests in such Global Notes may be effected only through a book-entry system maintained by the Depository or other Person that is the Holder of such Global Note (or its agent) in accordance
with the applicable legends thereon, and that ownership of a beneficial interest in the Note shall be required to be reflected in a book-entry system. 

SECTION 2.07 Replacement Notes. 
 If
a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate and deliver a replacement Note if the requirements
of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. Such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuer and the Trustee to protect
the Issuer, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note pursuant to this
Section 2.07, including reasonable fees and expenses of counsel and of the Trustee. 
 Every replacement Note issued pursuant to this
Section in lieu of any lost, destroyed or wrongfully taken Note shall constitute an original additional contractual obligation of the Issuer, whether or not the lost, destroyed or wrongfully taken Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder. 

In case any such mutilated, destroyed, lost or wrongfully taken Note has become or is about to become due and payable, the Issuer in its
discretion may, instead of issuing a new Note, pay such Note. 
 The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the replacement or payment of lost, destroyed or wrongfully taken Notes. 

SECTION 2.08 Outstanding Notes. 

Subject to Section 2.09, the Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those
cancelled by it, those paid pursuant to Section 2.07, 

  
 -40- 








 
delivered to it for cancellation and those described in this Section as not outstanding. Subject to Section 2.09, a Note does not cease to be outstanding because the Issuer, the Guarantors
or any of their respective Affiliates hold the Note. 
 If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note
surrendered for replacement), it ceases to be outstanding unless a Responsible Officer of the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be outstanding upon
surrender of such Note and replacement thereof pursuant to Section 2.07. 
 If the principal amount of any Note is considered paid
under Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on a Redemption Date or the Maturity Date the Trustee or Paying Agent (other than the Issuer or an Affiliate thereof) holds cash in Dollars or U.S. Government
Obligations, or a combination thereof, in amounts sufficient to pay all of the principal and interest due on the Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue. 

SECTION 2.09 Treasury Notes. 
 In
determining whether the Holders of the required principal amount of Notes have concurred in any request, demand, authorization, direction, notice, consent or waiver, Notes owned by the Issuer or an Affiliate of the Issuer shall be disregarded,
except that for, the purposes of determining whether the Trustee shall be protected in relying on any such request, demand, authorization, direction, notice, consent or waiver, only Notes that a Responsible Officer of the Trustee actually knows are
so owned shall be so disregarded. 
 SECTION 2.10 Temporary Notes. 

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall
be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Notes in exchange
for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as definitive Notes. Notwithstanding the foregoing, so long as the Notes are represented by a Global Note, such Global Note may
be in typewritten form. 
 SECTION 2.11 Cancellation. 

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any
Notes surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent (other than the Issuer or an Affiliate of the Issuer), and no one else, shall cancel and, at the written
direction of the Issuer, shall dispose of all Notes surrendered for transfer, exchange, payment or cancellation in accordance with its customary procedures. Certification of the destruction of all cancelled Notes shall be delivered to the Issuer
upon request by the Issuer. Subject to Section 2.07, the Issuer may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Issuer or any Guarantor shall acquire any of the


  
 -41- 








 
Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation
pursuant to this Section 2.11. 
 SECTION 2.12 Defaulted Interest. 

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent lawful) any
interest payable on the defaulted interest, in any lawful manner. The Issuer may pay the defaulted interest to the Persons who are Holders on a subsequent special record date, which date shall be the fifteenth (15th) day next preceding the date
fixed by the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least fifteen (15) days before any such subsequent special record date, the Issuer (or, upon the written
request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall mail to each Holder, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest,
and interest payable on such defaulted interest, if any, to be paid. 
 SECTION 2.13 CUSIP and ISIN Numbers. 

The Issuer in issuing the Notes may use “CUSIP” or “ISIN” numbers, and if so, the Trustee shall use the “CUSIP”
or “ISIN” numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the “CUSIP”
or “ISIN” numbers printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer will promptly notify the Trustee of any change in the “CUSIP” or
“ISIN” numbers. 
 SECTION 2.14 Deposit of Moneys. 

Subject to Section 2 of the Notes, prior to 10:00 a.m. New York City time on each Interest Payment Date, Maturity Date, Redemption Date,
Change of Control Payment Date and Net Proceeds Payment Date, the Issuer shall have deposited with the Paying Agent, in immediately available funds, funds in Dollars sufficient to make cash payments, if any, due on such Interest Payment Date,
Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity Date,
Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, as the case may be. 
 SECTION 2.15 Book-Entry Provisions for Global
Notes. 
 (a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository,
(ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in Exhibit B, as applicable.

 -42- 








 
the Trustee as its custodian, or under the Global Note, and the Depository may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner of the Global
Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer 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 Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Note. 

(b) The transfer and exchange of beneficial interests in Global Notes will be effected through the Depository, in accordance with the
provisions of this Indenture and the rules and procedures of the Depository that apply to such transfer or exchange. 
 (c) Transfers of
Global Notes shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged for Physical Notes in accordance
with the rules and procedures of the Depository and the provisions of Section 2.16. In addition, Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in Global Notes if (i) the Depository
notifies the Issuer that it is unwilling or unable to act as Depository for any Global Note, the Issuer so notifies the Trustee in writing and a successor Depository is not appointed by the Issuer within ninety (90) days of such notice or
(ii) a Default has occurred and is continuing and the Registrar has received a written request from any owner of a beneficial interest in a Global Note to issue Physical Notes. Upon any issuance of a Physical Note in accordance with this
Section 2.15(c), the Trustee shall be required to register such Physical Note in the name of, and cause the same to be delivered to, such Person or Persons (or the nominee of any thereof). All such Physical Notes shall bear any legends required
by applicable law. 
 (d) In connection with any transfer or exchange of a portion of the beneficial interest in a Global Note to beneficial
owners pursuant to Section 2.15(c), the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the principal
amount of the beneficial interest in the Global Note to be transferred, and the Issuer shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of authorized denominations in an aggregate principal amount equal to
the principal amount of the beneficial interest in the Global Note so transferred. 
 (e) In connection with the transfer of a Global Note
as an entirety to beneficial owners pursuant to Section 2.15(c), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and (i) the Issuer shall execute and (ii) the Trustee shall, upon written
instructions from the Issuer, authenticate and deliver to each beneficial owner identified by the Depository, in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Physical Notes of authorized
denominations. 
 (f) Any Physical Note constituting a Restricted Security delivered in exchange for an interest in a Global Note pursuant
to paragraph (c) or (d) of this Section 2.15 shall, except as otherwise provided by Section 2.16, bear the Private Placement Legend or, to the extent such Physical Note represents Notes sold to a Non-U.S. Person in reliance on
Regulation S, a Regulation S Legend.

 (g) The Holder of any Global Note, including the Depository, may grant proxies, appoint agents
and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to give or take any request, demand, authorization, direction, notice, consent, waiver or other action that a Holder is entitled to
take under this Indenture or the Notes. 
 (h) Except as provided in the last sentence of Section 2.08, the Issuer, the Trustee and any
Agent shall treat a Person as the Holder of such principal amount of outstanding Notes represented by a Global Note as shall be specified in a written statement of the Depository with respect to such Global Note, for purposes of obtaining any
consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture.

in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or 
 (2) if

provided, however, that, in the case of such redemption, the Trustee will select the Notes on a pro rata basis or on as nearly a pro
rata basis as practicable (subject to the procedures of the Depository), unless that method is otherwise prohibited. 
 The Trustee
shall promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in the amounts
of $1,000 or integral multiples of $1,000; provided, however, that no Note shall be redeemed in part if such Note would have a remaining principal amount of less than $2,000; provided further, however, that that if all of
the Notes of a Holder are to be redeemed, the entire outstanding amount of the Notes held by such Holder, even if not an integral multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that

including, the Redemption Date) upon surrender to the Trustee or Paying Agent of the Notes redeemed; 
 (6) if any Note is
being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date, and upon surrender and cancellation of such Note, a new Note or Notes in aggregate principal amount equal to the unredeemed
portion thereof will be issued;

(8) the Section of the Notes or this Indenture, as applicable, pursuant to which the Notes are to be redeemed. 

The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such
notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.
Notices of redemption, if conditional, shall specify the conditions to the redemption described therein. 
 At the Issuer’s request,
the Trustee shall give the notice of redemption in the Issuer’s name and at its expense. 
 SECTION 3.04 Effect of Notice of Redemption.

 Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption shall become due and payable on the
Redemption Date at the Redemption Price therefor plus accrued interest, if any, thereon to, but not including, the Redemption Date; provided that, any such redemption may, at the Issuer’s option, be subject to one or more
conditions precedent, including but not limited to the consummation of a Qualified Equity Offering or a Change of Control. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption shall be paid at the Redemption Price plus
accrued interest, if any, thereon to, but not including, the Redemption Date, provided that installments of interest whose Stated 

  
 -49- 








 
Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Notes registered at the close of business on the relevant Record Dates. On and after the Redemption Date
interest shall cease to accrue on Notes or portions thereof called for redemption unless the Issuer shall have not complied with its obligations pursuant to Section 3.05. 

SECTION 3.05 Deposit of Redemption Price. 

On or before 10:00 a.m. New York time on the Redemption Date, the Issuer shall deposit with the Paying Agent funds in Dollars sufficient to pay
the Redemption Price of all Notes to be redeemed on that date plus all accrued and unpaid interest, if any, thereon to, but not including, the Redemption Date. 

If the Issuer complies with the preceding paragraph, then, unless the Issuer defaults in the payment of such Redemption Price (together with
all accrued and unpaid interest, if any, thereon to, but not including, the Redemption Date) with respect to the Notes to be redeemed, interest on such Notes will cease to accrue on and after the applicable Redemption Date, whether or not such Notes
are presented for payment. 
 SECTION 3.06 Notes Redeemed in Part. 

Upon surrender of a Note that is to be redeemed in part, the notice of redemption that relates to such Note shall state the portion of the
principal amount thereof to be redeemed. A new Note or Notes of the same Maturity Date and equal in principal amount to the unredeemed portion of the original Note or Notes shall be issued in the name of the Holder thereof upon surrender and

 SECTION 4.02 Maintenance of Office or Agency. 

The Issuer covenants and agrees for the benefit of the Holders that it will maintain in the Borough of Manhattan, The City of New York, New
York the office or agency required under Section 2.03 (which may be an office or drop facility of the Trustee or the Registrar, as applicable, for such Notes or an Affiliate of such Trustee or the Registrar, as applicable, for such Notes) where
such Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of such Notes and this Indenture may be served. The Issuer will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with
Section 2.03. 
 SECTION 4.03 Corporate Existence.

necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of its Restricted Subsidiaries in accordance with the respective organizational
documents (as the same may be amended from time to time) of each such Restricted 
 Subsidiary and the material rights (charter and
statutory) and material franchises of the Issuer and each of its Restricted Subsidiaries; provided, however, that the Issuer shall not be required to preserve any such right or franchise with respect to itself or any Restricted
Subsidiary or any such corporate, partnership, limited liability company or other existence with respect to any Restricted Subsidiary if the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of the business
of the Issuer and its Restricted Subsidiaries, taken as a whole. 
 SECTION 4.04 Compliance Certificate. 

(a) The Issuer and each Guarantor (to the extent that such Guarantor is so required under the Trust Indenture Act) shall deliver to the

 -51- 








 
be the Issuer’s or Guarantor’s, as applicable, principal executive officer, principal financial officer or principal accounting officer (as such terms are defined in the Trust Indenture
Act), stating that a review of the activities of the Issuer or Guarantor, as applicable, has been made under the supervision of the signing officers with a view to determining whether it has kept, observed, performed and fulfilled its obligations
under this Indenture and further stating, as to each such Officer signing such certificate, that to such Officer’s knowledge, the Issuer or Guarantor, as applicable, during such preceding fiscal year has kept, observed, performed and fulfilled
each and every such covenant and no Default occurred during such year and at the date of such certificate there is no Default that has occurred and is continuing or, if such signers do know of such Default, the certificate shall describe its status
with particularity. 
 (b) Upon any Officer of the Issuer becoming aware of any Default, the Issuer shall deliver to the Trustee an
Officers’ Certificate specifying such Default and what action the Issuer is taking or proposes to take with respect thereto.

 -52- 








 SECTION 4.05 Waiver of Stay, Extension or Usury Laws. 

The Issuer and each Guarantor covenants (to the extent permitted by applicable law) that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive such Issuer or such Guarantor from paying all or any portion of the principal of or interest on the
Notes or the Guarantee of any such Guarantor as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and (to the extent permitted by applicable law)
each hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted. 
 SECTION 4.06 Change of Control. 

(a) Upon the occurrence of any Change of Control, each Holder of Notes will have the right to require the Issuer to repurchase all or any part
(equal to $1,000 or an integral multiple thereof; provided, however, that no Note shall be repurchased in part if such Note would have a remaining principal amount of less than $2,000) of that Holder’s Notes pursuant to a Change
of Control Offer (the “Change of Control Offer”). In the Change of Control Offer, the Issuer will offer to pay an amount in cash (the “Change of Control Purchase Price”) equal to 101% of the aggregate principal
amount of Notes purchased, plus accrued and unpaid interest thereon, if any, to but excluding the date of purchase. Within thirty (30) days following any Change of Control, the Issuer will mail, or cause to be mailed, a notice to each
Holder describing the transaction or transactions that constitute the Change of Control and offering to purchase Notes on the date (the “Change of Control Payment Date”) specified in such notice, which date shall be a Business Day
no earlier than thirty (30) days and no later than sixty (60) days from the date such notice is mailed, pursuant to the procedures described below. Such notice shall state: 

(1) that the Change of Control Offer is being made pursuant to this Section 4.06 and that all Notes tendered and not
withdrawn will be accepted for payment; 
 (2) the Change of Control Purchase Price and the Change of Control Payment Date;

 (3) that any Note not tendered will continue to accrue interest; 

(4) that, unless the Issuer defaults in making payment therefor, any Note accepted for payment pursuant to the Change of
Control Offer shall cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to have a
Note purchased pursuant to a Change of Control Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in
the notice prior to the close of business on the third (3rd) Business Day prior to the Change of Control Payment Date; 

  
 -53- 








 (6) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the second (2nd) Business Day prior to the Change of Control Payment Date, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder delivered for
purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 
 (7) that Holders whose
Notes are purchased only in part will be issued new Notes in a principal amount equal to the unpurchased portion of the Notes surrendered (equal to integral multiple of $1,000 but not less than $2,000); and 

(8) the circumstances and relevant facts regarding such Change of Control. 

(b) On or before the Change of Control Payment Date, the Issuer will, to the extent lawful: 

(1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer; 

(2) deposit with the Paying Agent funds sufficient to pay the Change of Control Purchase Price in respect of all Notes or
portions thereof so tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with
an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Issuer. 
 (c) The
Paying Agent will promptly mail to each Holder of Notes so tendered the Change of Control Purchase Price for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal
in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a principal amount equal to an integral multiple of $1,000 but not less than $2,000. 

(d) The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control
Payment Date. 
 (e) The Issuer will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party
makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer, or (2) notice of redemption has been given to the Trustee pursuant to the Indenture with respect to all of the Notes then outstanding as described under Section 5 or Section 7 of the
Notes, unless and until there is a default in payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, or conditioned upon the
consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. 

  
 -54- 








 (f) The Issuer shall cause the Change of Control Offer to remain open for at least twenty
(20) Business Days or for such longer period as may be required by law. The Issuer will comply, and will cause any third party making a Change of Control Offer to comply, with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with a Change of Control Offer. To the extent the provisions of any applicable securities laws or regulations conflict with the
provisions of this Section 4.06, the Issuer will not be deemed to have breached its obligations under this Section 4.06 by virtue of complying with such laws or regulations. 

(g) In the event that at the time of such Change of Control the terms of the Indebtedness under any Credit Agreement restrict or prohibit the
purchase of the Notes pursuant to this Section 4.06, then prior to the mailing of the notice to Holders provided for in Section 4.06(a), but in any event within thirty (30) days following any Change of Control, the Issuer shall
(i) repay in full the Indebtedness and terminate all commitments under such Credit Agreement or (ii) obtain the requisite consent under the agreements governing the Indebtedness under such Credit Agreement to permit the purchase of the
Notes as provided for in this Section 4.06. 
 (h) The Issuer shall first comply with the covenant in the immediately preceding
sentence before it shall be required to repurchase Notes or send the notice to the Holders referred to in clause (a) above pursuant to the provisions of this Section 4.06. The Issuer’s failure to comply with the covenant described in
the second preceding sentence (and any failure to send the notice referred to in clause (a) above because the same is prohibited by the second preceding sentence) may (with notice and lapse of time) constitute an Event of Default described in
Section 6.01(3) but shall not constitute an Event of Default described in Section 6.01(2). 
 (i) In the event that Holders of not
less than 90% in aggregate principal amount of the then outstanding Notes accept a Change of Control Offer and the Issuer (or any third party making such Change of Control Offer in lieu of the Issuer as described in Section 4.06(e)(1) above)
purchases all of the Notes held by such Holders, the Issuer will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described
above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Purchase Price plus accrued and unpaid interest on the Notes that remain outstanding, to the date of redemption,
subject to the rights of Holders of the Notes on the relevant regular record date to receive interest due on the relevant interest payment date that is on or prior to the applicable redemption date. 

SECTION 4.07 Limitations on Additional Indebtedness.

however, that the Issuer or any Restricted Subsidiary may incur additional Indebtedness, and the Issuer or any Restricted Subsidiary may incur Acquired Indebtedness if, after giving effect thereto, the Consolidated Interest Coverage Ratio would
be at least 2.00 to 1.00 (the “Coverage Ratio Exception”).

(without duplication) at any time outstanding under all Credit Facilities (including all Credit Agreements) (excluding Hedging Obligations related to the Indebtedness thereunder) does not exceed the greatest of (x) $2,350.0 million, less

pro forma basis for such transaction in accordance with the provisions set forth in the definition of “Consolidated Interest Coverage Ratio,” either: 

(A) the Issuer would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception,

than one of the categories of Permitted Indebtedness described in clauses (1) through (16) of Section 4.07(b) or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify
such item of Indebtedness and may divide and classify (and may later redivide and reclassify) such Indebtedness in more than one of the types of Indebtedness described in Section 4.07(a) or Section 4.07(b) in any manner that complies with
this Section 4.07, except that Indebtedness incurred under the Credit Agreement on the Issue Date shall be deemed to have been incurred under clause (1) of Section 4.07(b). Any item of Indebtedness entitled to be incurred pursuant to

SECTION 4.08 Limitations on Restricted Payments. 

(a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, make any Restricted Payment if at the time

 (2) the Issuer cannot incur $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or

Independent Financial Advisor (which opinion may be in the form of a fairness opinion with respect to the transaction in which the equity or assets are acquired), plus 

(iii) 100% of the aggregate net cash proceeds received by the Issuer as contributions to the common or preferred equity (other
than Disqualified Equity Interests) of the Issuer after the Issue Date, other than any such proceeds which are used to redeem Notes in accordance with Section 6 of the Notes, plus 

(iv) the aggregate amount by which Indebtedness incurred by the Issuer or any Restricted Subsidiary subsequent to the Issue
Date is reduced on the Issuer’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Issuer) of Indebtedness into Qualified Equity Interests (less the amount of any cash, or the fair value of assets,

declaration thereof, if on the date of declaration the payment would have complied with the provisions of this Indenture; 

(2) the redemption of any Equity Interests of the Issuer or any Restricted Subsidiary in exchange for, or out of the proceeds

 -61- 








 
a consequence thereof and (y) no issuance and sale of Qualified Equity Interests pursuant to clause (2) or (3) of this Section 4.08(b) shall increase the Restricted Payments
Basket, except to the extent the proceeds thereof exceed the amounts used to effect the transactions described therein.

Guarantee, effective provision is made to secure the Notes or such Guarantee, as the case may be, at least equally and ratably with or prior to such obligation with a Lien on the same collateral; and 

(b) in the case of any Lien securing an obligation that is subordinated in right of payment to the Notes or a Guarantee, effective provision
is made to secure the Notes or such Guarantee, as the case may be, with a Lien on the same collateral that is prior to the Lien securing such subordinated obligation, 

in each case, for so long as such obligation is secured by such Lien.

 (ii) the amount of any obligations received from such transferee that are within
one hundred eighty (180) days converted by the Issuer or such Restricted Subsidiary to cash (to the extent of the cash actually so received); 

(iii) the Fair Market Value of (x) any assets (other than securities) received by the Issuer or any Restricted Subsidiary
to be used by it in the Permitted Business, (y) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such
Person by the Issuer or (z) a combination of (x) and (y); and 
 (iv) the Fair Market Value of any Equity Interests
for which the Issuer or such Restricted Subsidiary has a contractual right to require the registration (or equivalent) of such Equity Interests under the Securities Act or the applicable securities laws of the jurisdiction in which such securities
are listed on a Major Foreign Exchange (“Designated Non-Cash Consideration”); provided, however, that no consideration received in an Asset Sale will constitute Designated Non-Cash Consideration if and to the extent
that the classification of such consideration as Designated Non-Cash Consideration would cause the aggregate amount of all such Designated Non-Cash Consideration outstanding at that time to exceed 2.5% of Consolidated Total Assets (with the Fair
Market Value of each item of Designated Non-Cash Consideration being measured at the time received and without giving effect to subsequent changes in value). 

(b) If at any time any non-cash consideration (including any Designated Non-Cash Consideration) received by the Issuer or any Restricted
Subsidiary of the Issuer, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of
such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.10. 

(c) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary shall, no later than 360
days following the consummation thereof, apply all or any (or, in the Issuer’s discretion, none) of the Net Available Proceeds therefrom to: 

(1) repay Senior Debt or Guarantor Senior Debt, and in the case of any such repayment under any revolving credit facility,
effect a permanent reduction in the availability under such revolving credit facility, in each case if and to the extent permitted under the terms of such Senior Debt or Guarantor Senior Debt; 

(2) repay any Indebtedness which was secured by the assets sold in such Asset Sale; or 

(3) (i) invest all or any part of the Net Available Proceeds thereof in assets (other than securities), including expenditures
for research and development activities, to be used by the Issuer or any Restricted Subsidiary in the Permitted Business, (ii) acquire 

  
 -63- 








 
Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such
acquisition or (iii) a combination of (i) and (ii). 
 The amount of Net Available Proceeds not applied or invested as provided in this paragraph
will constitute “Excess Proceeds.” The Issuer or such Restricted Subsidiary may repay Senior Debt or Guarantor Senior Debt under a revolving Credit Facility during the 360 days following the consummation of such Asset Sale without
effecting a permanent reduction in the availability under such revolving credit facility, pending application of such proceeds pursuant to clause (1), (2) or (3) of this Section 4.10(c) or their use as Excess Proceeds in accordance
with the next paragraph, and such repayment shall not be considered an application of Net Available Proceeds for purposes of this paragraph; provided, however, that, if such Net Available Proceeds are not applied after 360 days for any
purpose other than the repayment of a revolving credit facility, a permanent reduction in the availability under such revolving credit facility shall then be required in order for such repayment to be considered an application of Net Available
Proceeds for purposes of this paragraph. 
 (d) When the aggregate amount of Excess Proceeds equals or exceeds $50.0 million, the Issuer
will be required to make an offer to purchase from all Holders and, if applicable, redeem (or make an offer to do so) any Pari Passu Indebtedness of the Issuer the provisions of which require the Issuer to redeem such Pari Passu Indebtedness with
the proceeds from any Asset Sales (or offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal to the amount of such Excess Proceeds as follows: 

(1) the Issuer will (i) make an offer to purchase (a “Net Proceeds Offer”) to all Holders in accordance
with the procedures set forth in this Indenture, and (ii) redeem (or make an offer to do so) any such other Pari Passu Indebtedness, on a pro rata basis (or on as nearly a pro rata basis as is practicable) in proportion to the
respective principal amounts of the Notes and such other Pari Passu Indebtedness required to be redeemed, the maximum principal amount of Notes (in each case in whole in a principal amount of $1,000 or integral multiples thereof; provided,
however, that no Note will be purchased in part if such Note would have a remaining principal amount of less than $2,000) and Pari Passu Indebtedness that may be redeemed out of the amount (the “Payment Amount”) of such Excess
Proceeds; 
 (2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the principal amount of
the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the “Offered Price”), in accordance with the procedures set forth in
this Indenture, and the redemption price for such Pari Passu Indebtedness (the “Pari Passu Indebtedness Price”) shall be as set forth in the related documentation governing such Indebtedness; 

(3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders thereof exceeds the pro rata
portion of the Payment Amount allocable to the Notes, Notes to be purchased will be selected on a pro rata basis (or on as nearly a pro rata basis as is practicable); and 

  
 -64- 








 (4) upon completion of such Net Proceeds Offer in accordance with the foregoing
provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero. 
 (e) To the
extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer and the aggregate Pari Passu Indebtedness Price paid to the holders of such Pari Passu Indebtedness is less than the Payment Amount relating
thereto (such shortfall constituting a “Net Proceeds Deficiency”), the Issuer may use the Net Proceeds Deficiency, or a portion thereof, for general corporate purposes, subject to the provisions of this Indenture, and the amount of
Excess Proceeds with respect to such Net Proceeds Offer shall be deemed to be zero. 
 (f) Upon the commencement of a Net Proceeds Offer,
the Issuer shall send or cause to be sent, by first class mail, a notice to the Trustee and to each Holder at its registered address. The notice shall contain all instructions and materials necessary to enable such Holder to tender Notes pursuant to
the Net Proceeds Offer. Any Net Proceeds Offer shall be made to all Holders. The notice, which shall govern the terms of the Net Proceeds Offer, shall state: 

(1) that the Net Proceeds Offer is being made pursuant to this Section 4.10; 

(2) the Payment Amount, the Offered Price, and the date on which Notes tendered and accepted for payment shall be purchased,
which date shall be at least thirty (30) days and not later than sixty (60) days from the date such notices is mailed (the “Net Proceeds Payment Date”); 

(3) that any Notes not tendered or accepted for payment shall continue to accrue interest; 

(4) that, unless the Issuer defaults in making such payment, any Notes accepted for payment pursuant to the Net Proceeds Offer
shall cease to accrue interest on and after the Net Proceeds Payment Date; 
 (5) that Holders electing to have any Notes
purchased pursuant to any Net Proceeds Offer shall be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the Issuer, a
depository, if appointed by the Issuer, or the Paying Agent at the address specified in the notice at least three (3) days before the Net Proceeds Payment Date; 

(6) that Holders shall be entitled to withdraw their election if the Issuer, the Depository or the Paying Agent, as the case
may be, receives, not later than the Net Proceeds Payment Date, a notice setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have
such Note purchased; 
 (7) that if the aggregate principal amount of Notes surrendered by Holders exceeds the Payment
Amount, the Issuer shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Issuer so that 

  
 -65- 








 
only Notes in denominations of $1,000, or integral multiples thereof, shall be purchased; provided, however, that no Note will be purchased in part if such Note would have a
remaining principal amount of less than $2,000); and 
 (8) that Holders whose Notes were purchased only in part shall be
issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry); provided, however, that each such new Note will be in a principal amount equal to an integral multiple of
$1,000 but not less than $2,000. 
 (g) On the Net Proceeds Payment Date, the Issuer shall, to the extent lawful: (1) accept for
payment all Notes or portions thereof properly tendered pursuant to the Net Proceeds Offer, subject to pro ration if the aggregate Notes tendered exceed the Payment Amount allocable to the Notes; (2) deposit with the Paying Agent funds in
Dollars equal to the lesser of the Payment Amount allocable to the Notes and the amount sufficient to pay the Offered Price in respect of all Notes or portions thereof so tendered; and (3) deliver or cause to be delivered to the Trustee the
Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being repurchased by the Issuer. The Issuer shall publicly announce the results of the Net Proceeds Offer on or as soon
as practicable after the Net Proceeds Payment Date. 
 (h) The Paying Agent shall promptly mail to each Holder of Notes so tendered the
Offered Price for such Notes, and the Trustee shall promptly authenticate pursuant to an Authentication Order and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unrepurchased portion of the
Notes surrendered, if any; provided, however, that each such new Note shall be in principal amount equal to an integral multiple of $1,000 but not less than $2,000. However, if the Net Proceeds Payment Date is on or after an interest
Record Date and on or before the related interest payment date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such Record Date, and no additional interest shall be payable
to Holders who tender Notes pursuant to the Net Proceeds Offer. 
 (i) The Issuer shall comply with applicable tender offer rules, including
the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this Section 4.10, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of this compliance.

 SECTION 4.11 Limitations on Transactions with Affiliates. 

(a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, in one transaction or a series of related
transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an
“Affiliate Transaction”), unless: 
 (1) such Affiliate Transaction is on terms that are no less favorable
to the Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction at such time on an arm’s-length basis by the Issuer or that Restricted Subsidiary from a Person that is not an Affiliate of
the Issuer or that Restricted Subsidiary; and 
 (2) the Issuer delivers to the Trustee: 

(i) with respect to any Affiliate Transaction involving aggregate value expended by the Issuer or any Restricted Subsidiary in
a consecutive twelve-month period in excess of $15.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and a Secretary’s Certificate which sets forth and authenticates a
resolution that has been adopted by a majority of the Independent Directors approving such Affiliate Transaction; and 
 (ii)
with respect to any Affiliate Transaction involving aggregate value expended by the Issuer or any Restricted Subsidiary in a consecutive twelve-month period of $50.0 million or more, the certificates described in the preceding clause (i) and a
written opinion as to the fairness of such Affiliate Transaction to the Issuer or such Restricted Subsidiary from a financial point of view issued by an Independent Financial Advisor. 

(b) The foregoing restrictions shall not apply to: 

(1) transactions exclusively between or among (i) the Issuer and one or more Restricted Subsidiaries or
(ii) Restricted Subsidiaries, provided, in each case, that no Affiliate of the Issuer (other than another Restricted Subsidiary) owns Equity Interests of any such Restricted Subsidiary; 

(2) director, officer and employee compensation (including bonuses) and other benefits (including retirement, health, stock
option and other benefit plans) and indemnification and insurance arrangements; 
 (3) the entering into of any tax sharing
agreement, or the making of payments pursuant to any such agreement, between the Issuer or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated
tax return or with which the Issuer or such Subsidiaries are part of a consolidated group for tax purposes, on the other hand, which payments by the Issuer and the Subsidiaries are not materially in excess of the tax liabilities that would have been
payable by them on a stand-alone basis; 

  
 -67- 








 (4) any Permitted Investments; 

(5) Restricted Payments which are made in accordance with Section 4.08 (including payments and transactions that would
constitute Restricted Payments but for the exclusions in clauses (1) and (2) of the definition thereof); 
 (6) any
transaction with an Affiliate where the only consideration paid by the Issuer or any Restricted Subsidiary is Qualified Equity Interests (and any payments of cash in lieu of delivering fractional shares in connection therewith); 

(7) the sale to an Affiliate of the Issuer of Equity Interests of the Issuer that do not constitute Disqualified Equity
Interests, and the sale to an Affiliate of the Issuer of Indebtedness (including Disqualified Equity Interests) of the Issuer in connection with an offering of such Indebtedness in a market transaction and on terms substantially identical to those
of other purchasers in such market transaction who are not Affiliates; 
 (8) any transaction with a joint venture in which
the Issuer or a Restricted Subsidiary is a joint venturer and no other Affiliate is a joint venturer, or with any Subsidiary thereof or other joint venturer therein, pursuant to the joint venture agreement or related agreements for such joint
venture, including any transfers of any equity or ownership interests in any such joint venture to any other joint venturer therein pursuant to the performance or exercise of any rights or obligations to make such transfer under the terms of the
agreements governing such joint venture; or 
 (9) without limiting clause (8) immediately above, (i) any
transaction with a P&G JV Company or any Subsidiary or member thereof pursuant to the P&G JV Agreements or (ii) any other transactions with a P&G JV Company or any Subsidiary or member thereof for the manufacturing, packaging,
supply or distribution of products or materials, or the provision of other administrative or operational services (whether on a transitional or ongoing basis), solely with respect to the consumer diagnostic business, so long as, with respect to this
clause (ii), the charges for manufacturing such products are on a “cost-plus” basis. 
 The foregoing restrictions in
Section 4.11(a)(2) shall not apply to ordinary course transactions between the Issuer or any Restricted Subsidiary and an Unrestricted Subsidiary. 

SECTION 4.12 Limitations on Dividend and Other Restrictions Affecting Restricted Subsidiaries. 

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or
become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to: 
 (a) pay dividends
or make any other distributions on or in respect of its Equity Interests; 
 (b) make loans or advances, or pay any Indebtedness or other
obligation owed, to the Issuer or any other Restricted Subsidiary; or

restrictions existing under or by reason of applicable law; 
 (2) encumbrances or restrictions existing under the Indenture
(including the Guarantees) and the Notes;

permitted hereunder); 
 (5) encumbrances or restrictions under any Credit Facility (including any Credit Agreement)
(including with regard to future Restricted Subsidiaries); 
 (6) restrictions on the transfer of assets subject to any Lien
imposed by the holder of such Lien; 
 (7) restrictions on the transfer of assets imposed under any agreement to sell such
assets to any Person pending the closing of such sale; 
 (8) encumbrances or restrictions under any instrument governing
Acquired Indebtedness that are not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired; 

(9) encumbrances or restrictions under any other agreement entered into after the Issue Date that are, in the good faith
judgment of the Issuer, not materially more restrictive, taken as a whole, with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary (or any future Restricted Subsidiary) pursuant to
agreements in effect on the Issue Date (including the Indenture, the Senior Notes Indenture, the Existing Senior Subordinated Notes Indentures and the Credit Agreement); 

(10) restrictions under customary provisions in partnership agreements, limited liability company organizational or governance
documents, joint venture agreements, corporate charters, stockholders’ agreements, and other similar agreements and documents on the transfer of ownership interests in such partnership, limited liability company, joint venture or similar
Person; 

  
 -69- 








 (11) encumbrances or restrictions imposed under Purchase Money Indebtedness on
the assets acquired that are of the nature described in clause (c) above, provided such Purchase Money Indebtedness is incurred in compliance with Section 4.07; 

(12) restrictions of the nature described in clause (c) above contained in any security agreement or mortgage securing
Indebtedness or other obligations of the Issuer or any Restricted Subsidiary to the extent such restrictions restrict the transfer of the property subject to such security agreement or mortgage; and 

(13) any encumbrances or restrictions imposed by any amendments or refinancings of the contracts, instruments or obligations
referred to in clauses (1) through (12) above; provided, however, that such encumbrances or restrictions are, in the good faith judgment of the Issuer, no more materially restrictive, taken as a whole, than those in effect
prior to such amendment or refinancing. 
 SECTION 4.13 Additional Guarantees. 

(a) If, after the Issue Date, (i) the Issuer or any Restricted Subsidiary acquires or creates a Domestic Subsidiary that guarantees any
Indebtedness or other Obligation under any Credit Agreement (other than a Subsidiary that has been designated an Unrestricted Subsidiary), (ii) any Unrestricted Subsidiary that is a Domestic Subsidiary that guarantees any Indebtedness or other
Obligation under any Credit Agreement is redesignated a Restricted Subsidiary, then, in each such case, the Issuer shall cause such Restricted Subsidiary to execute and deliver to the Trustee a supplemental indenture in the form of Exhibit E
attached to this Indenture, pursuant to which such Restricted Subsidiary shall unconditionally and irrevocably guarantee all of the Issuer’s obligations under the Notes and this Indenture. Thereafter, such Restricted Subsidiary shall be a
Guarantor for all purposes of this Indenture. 
 (b) Notwithstanding Section 4.13(a), a Subsidiary Guarantor will be automatically and
unconditionally released and discharged from its obligations under its Guarantee and this Indenture under the circumstances set forth in Section 11.04. 

SECTION 4.14 Limitation on Layering Indebtedness. 

(a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur any Indebtedness that by its terms (or
by the terms of any agreement governing such Indebtedness) is or purports to be senior in right of payment to the Notes or the Guarantee, if any, of such Restricted Subsidiary and subordinated in right of payment to any other Indebtedness of the
Issuer or of such Restricted Subsidiary, as the case may be. 
 (b) For purposes of Section 4.14(a), no Indebtedness will be deemed to
be subordinated in right of payment to any other Indebtedness of the Issuer or any Restricted Subsidiary solely by virtue of being unsecured or by virtue of the fact that the holders of such Indebtedness have entered into intercreditor agreements or
other arrangements giving one or more of such holders priority over the other holders in the collateral held by them or by virtue of structural subordination. 

  
 -70- 








 SECTION 4.15 SEC Reports. 

(a) Whether or not required by the SEC’s rules and regulations, so long as any Notes are outstanding, the Issuer will furnish to the
Holders, cause the Trustee to furnish to the Holders, or file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system, including the Interactive Data Electronic
Applications System), within 15 days after the time periods (including any extensions thereof) applicable to (or that would be applicable to) the Issuer under the SEC’s rules and regulations: 

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on
Forms 10-Q or 10-K (or any successor forms), as the case may be, if the Issuer were required to file these Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with
respect to the annual information only, a report on the annual financial statements by the Issuer’s independent accountants; and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K (or any successor form) if the Issuer were
required to file these reports; provided, that the Issuer shall not be obligated to furnish or file (i) any current report on Form 8-K if the Issuer determines in its good faith judgment that the information reportable therein is
not material to the Holders of the Notes or the business, assets, operations, financial position or prospects of the Issuer and its Restricted Subsidiaries, taken as a whole, or (ii) any agreements, financial statements or other items that
would be required to be filed as exhibits to a current report on Form 8-K. 
 In addition, whether or not required by the SEC’s rules and regulations,
the Issuer will file a copy of all of the information and reports referred to in clauses (a)(1) and (a)(2) of this Section 4.15 with the SEC for public availability within the time periods applicable to the Issuer under Section 13(a) or
15(d) of the Exchange Act (unless the SEC will not accept the filing, in which case the Issuer shall make the information available to securities analysts and prospective investors upon request). For so long as any Notes remain outstanding, the
Issuer will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. The Issuer also shall comply with the other
provisions of Trust Indenture Act § 314(a). 
 (b) Delivery of such reports and information to the Trustee shall be for informational
purposes only and the Trustee’s receipt of them shall not constitute constructive notice of any information contained therein or determinable from information contained therein (including the Issuer’s compliance with any of its covenants
under this Indenture as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate). 

  
 -71- 








 SECTION 4.16 Limitations on Designation of Unrestricted Subsidiaries. 

(a) The Issuer may designate any Subsidiary of the Issuer (including any newly acquired or newly formed Subsidiary) as an “Unrestricted
Subsidiary” under this Indenture (a “Designation”) only if: 
 (1) no Default shall have occurred and
be continuing at the time of or after giving effect to such Designation; and 
 (2) the Issuer would be permitted to make, at
the time of such Designation, (i) a Permitted Investment or (ii) an Investment pursuant to Section 4.08(a), in either case, in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s
proportionate interest in such Subsidiary on such date, less, for this purpose, the amount of any intercompany loan from the Issuer or any Restricted Subsidiary to such Subsidiary that was treated as a Restricted Payment. 

(b) No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless such Subsidiary: 

(1) has no Indebtedness other than Non-Recourse Debt; 

(2) is not party to any agreement, contract, arrangement or understanding with the Issuer or any Restricted Subsidiary unless
the terms of the agreement, contract, arrangement or understanding are no less favorable to the Issuer or the Restricted Subsidiary than those that might be obtained at the time from Persons who are not Affiliates; 

(3) is a Person with respect to which neither the Issuer nor any Restricted Subsidiary has any direct or indirect obligation
(a) to subscribe for additional Equity Interests or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results; and 

(4) has not guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Issuer or any
Restricted Subsidiary in excess of $25.0 million in the aggregate, except for any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not
recourse to the Issuer or any Restricted Subsidiary, and except to the extent the amount thereof constitutes a Restricted Payment permitted pursuant to Section 4.08. 

(c) If, at any time, any Unrestricted Subsidiary fails to meet the requirements of Section 4.16(a) and (b) as an Unrestricted
Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of
the date of such cessation and, if the Indebtedness is not permitted to be incurred under Section 4.07 or the Lien is not permitted under Section 4.09, the Issuer shall be in default of the applicable covenant. 

  
 -72- 








 (d) The Issuer may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a
“Redesignation”) only if: 
 (1) no Default shall have occurred and be continuing at the time of and after
giving effect to such Redesignation; and 
 (2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary
outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture. 

(e) All Designations and Redesignations must be evidenced by (1) resolutions of the Board of Directors of the Issuer and (2) an
Officers’ Certificate certifying compliance with the foregoing provisions, in each case delivered to the Trustee. 
 SECTION 4.17 Conduct of
Business. 
 The Issuer will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Permitted
Business. 
 SECTION 4.18 Limitations on Sale and Leaseback Transactions. 

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, enter into any Sale and Leaseback Transaction;
provided, however, that the Issuer or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if: 
 (a) the
Issuer or such Restricted Subsidiary could have (1) incurred the Indebtedness attributable to such Sale and Leaseback Transaction pursuant to Section 4.07 and (2) incurred a Lien to secure such Indebtedness without equally and ratably
securing the Notes pursuant to Section 4.09; 
 (b) the gross cash proceeds of such Sale and Leaseback Transaction are at least equal
to the Fair Market Value of the asset that is the subject of such Sale and Leaseback Transaction; and 
 (c) the transfer of assets in such
Sale and Leaseback Transaction is permitted by, and the Issuer or the applicable Restricted Subsidiary applies the proceeds of such transaction in accordance with, Section 4.10. 

SECTION 4.19 Suspension of Covenants. 

(a) During any period of time following the issuance of the Initial Notes that (i) the Notes have a rating equal to or higher than Baa3
(or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P, or, if either or both shall not make a rating on the Notes publicly available, from a nationally recognized statistical rating agency or agencies, as the case may be,
selected by the Issuer that shall be substituted for Moody’s or S&P or both, as the case may be (Moody’s, S&P or such other agency or agencies, as the case may be, the “Rating Agencies”), an equivalent rating by
such other agency or agencies, as the case may be (any such rating, an “Investment Grade Rating”), and (ii) no Default has occurred and is continuing under this 

  
 -73- 








 
Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the Issuer and
the Restricted Subsidiaries shall not be subject to the following provisions of this Indenture: 
  

	 	(1)	Section 4.07; 

  

	 	(2)	Section 4.08; 

  

	 	(3)	Section 4.10; 

  

	 	(4)	Section 4.11; 

  

	 	(5)	Section 4.12; 

  

	 	(6)	Section 4.18; and 

  

	 	(7)	Section 5.01(a)(iii) 

 (collectively, the “Suspended Covenants”). Upon the occurrence of
a Covenant Suspension Event, the amount of Net Available Proceeds with respect to any applicable Asset Sale shall be set at zero at such date (the “Suspension Date”). In the event that the Issuer and the Restricted 

Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the foregoing, and on any subsequent date (the
“Reversion Date”) one or both of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to the Notes below an Investment Grade Rating or a Default occurs and is continuing, then the Issuer and
the Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants, but only with respect to events after the Reversion Date. The period of time between the Suspension Date and the Reversion Date is referred to as the
“Suspension Period.” Notwithstanding that the Suspended Covenants may be reinstated, no Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the Suspension Period. 

(b) On the Reversion Date, all Indebtedness incurred during the Suspension Period will be subject to Section 4.07. To the extent such
Indebtedness would not be so permitted to be incurred pursuant to Section 4.07, such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.07(b)(3). 

(c) Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.08 will be made
as though Section 4.08 had been in effect from the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will be deemed to have been permitted but will reduce the amount available to
be made as Restricted Payments under Section 4.08(a). 
 (d) The Issuer shall give the Trustee notice of any Covenant Suspension Event
and in any event not later than five (5) Business Days after such Covenant Suspension Event. In the absence of such notice, the Trustee shall assume the Suspended Covenants apply and are in full force and effect. The Issuer shall give the
Trustee notice of any occurrence of a Reversion Date not later than five (5) Business Days after such Reversion Date. After any such notice of the occurrence of a Reversion Date, the Trustee shall assume the Suspended Covenants apply and are in
full force and effect. 

  
 -74- 








 (e) During a Suspension Period, the Issuer may not designate a Subsidiary as an Unrestricted
Subsidiary under Section 4.16. 
 (f) Notwithstanding the foregoing, neither (1) the continued existence, after the Reversion
Date, of facts and circumstances or obligations that occurred, were incurred or otherwise came into existence during a Suspension Period nor (2) the performance of any such obligations, shall constitute a breach of any Suspended Covenant set
forth in this Indenture or cause a Default hereunder; provided that (i) the Issuer and the Restricted Subsidiaries did not incur or otherwise cause such facts and circumstances or obligations to exist in anticipation of a withdrawal or
downgrade by the applicable Rating Agency below an Investment Grade Rating and (ii) the Issuer reasonably believed that such incurrence or actions would not result in such withdrawal or downgrade. The Issuer shall inform the Trustee of the
occurrence of a Covenant Suspension Event or a Reversion Date and in the absence of any such notice, the Trustee shall be entitled to assume that no such event occurred.

convey or otherwise dispose of or assign all or substantially all of the assets of the Issuer or the Issuer and the Restricted Subsidiaries (taken as a whole) to any other Person or (2) effect a Plan of Liquidation unless, in either case: 

(i) either: 

(x) the Issuer will be the surviving or continuing Person; or 

(y) the Person formed by or surviving such consolidation or merger (if not the Issuer) or to which such sale, lease,
conveyance or other disposition shall be made (or, in the case of a Plan of Liquidation, any Person to which assets are transferred) (collectively, the “Successor”) is a corporation organized and existing under the laws of any State
of the United States of America or the District of Columbia, and the Successor expressly assumes, by a supplemental indenture hereto in form and substance satisfactory to the Trustee, all of the obligations of the Issuer under the Notes and this
Indenture; 
 (ii) immediately after giving effect to such transaction and the assumption of the obligations as set forth in
clause (a)(i)(y) above, if applicable, and the incurrence of any Indebtedness to be incurred in connection therewith, no Default shall have occurred and be continuing; and 

  
 -75- 








 (iii) except in the case of the consolidation or merger of any Restricted
Subsidiary with or into the Issuer, immediately after giving effect to such transaction and the assumption of the obligations set forth in clause (a)(i)(y) above, if applicable, and the incurrence of any Indebtedness to be incurred in connection
therewith, and the use of any net proceeds therefrom on a pro forma basis, either (A) the Issuer or the Successor, as the case may be, could incur $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception or (B) the
Consolidated Interest Coverage Ratio of the Issuer or the Successor, as the case may be, determined on a pro forma basis for such transaction, would not be lower than the Consolidated Interest Coverage Ratio of the Issuer immediately prior to
such transaction. 
 For purposes of this Section 5.01, any Indebtedness of the Successor which was not Indebtedness of the Issuer immediately prior to
the transaction shall be deemed to have been incurred in connection with such transaction. 
 (b) Except as provided under Article Eleven,

all of the assets of one or more Restricted Subsidiaries, the Equity Interests of which constitute all or substantially all of the assets of the Issuer, will be deemed to be the transfer of all or substantially all of the assets of the Issuer. 

(d) Except as provided under Article Eleven, upon any consolidation, combination or merger of the Issuer or a Guarantor, or any sale, lease,
transfer, conveyance or other disposition or assignment of all or substantially all of the assets of the Issuer in accordance with the foregoing, in which the Issuer or such Guarantor is not the continuing obligor or continuing guarantor, as the
case may be, under the Notes or its Guarantee, the surviving entity formed by such consolidation or into which the Issuer or such Guarantor is merged or the entity to which the sale, lease, transfer, conveyance or other disposition or assignment is
made will succeed to, 

  
 -76- 








 
and be substituted for, and may exercise every right and power of, the Issuer or such Guarantor under this Indenture, the Notes and the Guarantee with the same effect as if such surviving entity
had been named therein as the Issuer or such Guarantor, and, except in the case of a lease, the Issuer or such Guarantor, as the case may be, will be released from the obligation to pay the principal of and interest on the Notes or in respect of its
Guarantee, as the case may be, and all of the Issuer’s or such Guarantor’s other obligations and covenants under the Notes and this Indenture. 

(e) Notwithstanding the foregoing in this Section 5.01, any Restricted Subsidiary may merge into the Issuer or another Restricted
Subsidiary.

(4) default under any mortgage, indenture or other instrument or agreement under which there may be issued or by which there
may be secured or evidenced Indebtedness of the Issuer or any Restricted Subsidiary, whether such Indebtedness exists on the Issue Date or is incurred thereafter, which default: 

(i) is caused by a failure to pay at final maturity (giving effect to any applicable grace periods and any extensions thereof)
principal on such Indebtedness, or 

  
 -77- 








 (ii) results in the acceleration of such Indebtedness prior to its express final
maturity, 
 and, in each case, the principal amount of such Indebtedness, together with any other Indebtedness with respect to which an
event described in clause (i) or (ii) has occurred and is continuing, aggregates $50.0 million or more; 
 (5)
entry by a court or courts of competent jurisdiction against the Issuer or any Restricted Subsidiary of one or more final judgments or orders for the payment of money that exceed $50.0 million in the aggregate (net of amounts covered by insurance or

of the Issuer or any Significant Subsidiary, or 
 (iii) orders the liquidation of the Issuer or any Significant Subsidiary,

 and the order or decree remains unstayed and in effect for sixty (60) days; or 

(8) (i) the Guarantee of any Significant Subsidiary (A) ceases to be in full force and effect (other than in accordance
with the terms of this Indenture (including such Guarantee)) or (B) is declared null and void and unenforceable or found to be invalid, and such circumstance or event remains uncured for a period of thirty (30) days, or (ii) any
Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor from its Guarantee in accordance with the terms of this Indenture (including such Guarantee)). 

  
 -78- 








 SECTION 6.02 Acceleration. 

(a) If an Event of Default specified in Section 6.01(6) or Section 6.01(7) with respect to the Issuer occurs, all outstanding Notes
shall become immediately due and payable without any further action or notice. If an Event of Default (other than an Event of Default specified in Section 6.01(6) or Section 6.01(7) with respect to the Issuer) shall have occurred and be
continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may
declare all amounts owing under the Notes to be due and payable, which notice shall specify each applicable Event of Default and that it is a “notice of acceleration” (an “Acceleration Notice”). Upon proper delivery of an
Acceleration Notice, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable (a) if there is any Designated Senior Debt outstanding at such time, with respect to any acceleration arising
out of any Event of Default other than a payment default under Section 6.01(1) or Section 6.01(2), upon the earlier of (x) the date which is five (5) Business Days after receipt by the Representatives of such Acceleration Notice
or (y) the date of acceleration of any Designated Senior Debt and (b) if otherwise, immediately, but, in any case, only if one or more of the Events of Default specified in such Acceleration Notice are then continuing; provided,
however, that after such declaration of acceleration, but before a judgment or decree based on acceleration, the Holders of at least a majority in aggregate principal amount of the then outstanding Notes may, on behalf of all of the Holders,
rescind and annul such declaration of acceleration and its consequences: 
 (1) if the rescission would not conflict with any
judgment or decree; 
 (2) if all existing Events of Default have been cured or waived (except nonpayment of principal and
interest that has become due solely because of such declaration of acceleration); 
 (3) to the extent the payment of such
interest is lawful, interest on overdue installments of interest and overdue principal, which has become due (otherwise than by such declaration of acceleration), has been paid; and 

(4) if the Issuer has paid to the Trustee its reasonable compensation and reimbursed the Trustee of its expenses, disbursements
and advances; 
 (5) in the event of a cure or waiver of an Event of Default of the type set forth in Section 6.01(6) or
Section 6.01(7), the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. 

No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

(b) The Issuer shall provide prompt notice to the holders of Senior Debt and Guarantor Senior Debt of any acceleration pursuant to
Section 6.02(a). 

  
 -79- 








 SECTION 6.03 Other Remedies. 

If a Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of
principal of, or interest on, the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The Trustee may
maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon a Default shall not impair the
right or remedy or constitute a waiver of or acquiescence in the Default. No remedy is exclusive of any other remedy. All remedies are cumulative to the extent permitted by law. 

SECTION 6.04 Waiver of Past Defaults. 

Subject to Section 2.09, Section 6.07 and Section 9.02, the Holders of at least a majority in aggregate principal amount of the
then outstanding Notes, by notice to the Trustee, may, on behalf of all of the Holders of such Notes, waive (which may include waivers obtained in connection with a tender offer or exchange offer for Notes), an existing Default and its consequences,
except a Default in the payment of principal or interest on such Notes as specified in Section 6.01(1) or Section 6.01(2). When a Default is waived, it is cured and ceases. 

SECTION 6.05 Control by Majority. 

(a) The Holders of at least a majority in principal amount of the then outstanding Notes shall have the right to direct the time, method and
place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law
or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction. 
 (b) In the event the Trustee takes any action or follows any
direction pursuant to this Indenture, the Trustee shall be entitled to indemnification against any loss or expense caused by taking such action or following such direction. 

SECTION 6.06 Limitation on Suits. 

(a) Subject to Section 6.07, no Holder will have any right to institute any proceeding with respect to this Indenture or the Notes or for
any remedy thereunder, unless the Trustee: 
 (1) has failed to act for a period of sixty (60) consecutive days after
receiving notice of a continuing Event of Default from such Holder and a request to act by Holders of at least twenty-five percent (25%) in aggregate principal amount of the then outstanding Notes; 

(2) has been offered indemnity satisfactory to it in its reasonable judgment; and 

  
 -80- 








 (3) has not received from the Holders of a majority in aggregate principal amount
of the then outstanding Notes a direction inconsistent with such request. 
 (b) A Holder may not use this Indenture to prejudice the rights
of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

 SECTION 6.07 Rights of Holders to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, and interest on, a Note, on
or after the respective due dates expressed in such Note (including, if applicable, in connection with an offer to purchase or redeem), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired
or affected without the consent of such Holder. 
 SECTION 6.08 Collection Suit by Trustee. 

If a Default in payment of principal or interest specified in Section 6.01(1) or Section 6.01(2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for the whole amount of principal and accrued interest and fees remaining unpaid, together with interest on overdue
principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by the Notes and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

SECTION 6.09 Trustee May File Proofs of Claim. 

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relating to the Issuer, their creditors or their property and shall
be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agent and counsel, and any other amounts due the Trustee under this Indenture. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee shall be entitled to
participate as a member of any official committee of creditors in the matters as it deems necessary or advisable. 

  
 -81- 








 SECTION 6.10 Priorities. 

If the Trustee collects any money or property pursuant to this Article Six, it shall pay out the money or property in the following order: 

First: to the Trustee for amounts due under Section 7.07; 

Second: to Holders for interest accrued on the Notes, ratably, without preference or priority of any kind, according to the amounts due
and payable on the Notes for interest; 
 Third: to Holders for principal amounts due and unpaid on the Notes, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Notes for principal; and 
 Fourth: to the Issuer
or, if applicable, the Guarantors, as their respective interests may appear, or to such other Person or Persons as a court of competent jurisdiction shall direct. 

The Trustee, upon prior notice to the Issuer, may fix a record date and payment date for any payment to Holders pursuant to this
Section 6.10. 
 SECTION 6.11 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted
by it as the Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by
a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than ten percent (10%) in aggregate principal amount of the then outstanding Notes. 

ARTICLE SEVEN 
 TRUSTEE 

SECTION 7.01 Duties of Trustee. 
 (a)
If a Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the

the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 

(c) Notwithstanding anything to the contrary in this Indenture, the Trustee may not be relieved from liability for its own negligent action,
its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this paragraph does not limit the effect

performance of any of its duties hereunder or to take or omit to take any action under this Indenture or take any action at the request or direction of Holders if it shall have reasonable grounds for believing that repayment of such funds is not
assured to it. 
 (e) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee
is subject to this Section 7.01. 
 (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee

opinion (including any Opinion of Counsel), notice, request, direction, consent, order, bond, debenture, or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not
investigate any fact or matter stated in such document. 

  
 -83- 








 (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate

 (f) The Trustee shall be under no obligation to
exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity
reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby. 
 (g) The Trustee shall
not be bound to make any investigation into the facts or matters stated in any resolution, certificate (including any Officers’ Certificate), statement, instrument, opinion (including any Opinion of Counsel), notice, request, direction,
consent, order, bond, debenture, or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee shall determine to make such further
inquiry or investigation, it shall be entitled, upon reasonable notice to the Issuer, to examine the books, records, and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer.

Section 6.01(1) or Section 6.01(2) or (ii) any Default of which the Trustee shall have received written notification. 
 (k)
The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and
other Person employed to act for it hereunder. 

  
 -84- 








 (l) In no event shall the Trustee be responsible or liable for special, indirect, punitive or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

(m) The Trustee may request that the Issuer deliver a certificate setting forth the names of individuals or titles of officers authorized at
such time to take specified actions pursuant to this Indenture. 
 SECTION 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its
Subsidiaries or their respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 

SECTION 7.04 Trustee’s Disclaimer. 

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall
not be accountable for the Issuer’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer in this Indenture or any document issued in connection with the sale of Notes or any statement in the Notes
other than the Trustee’s certification of its authentication. 
 SECTION 7.05 Notice of Default. 

If a Default occurs and is continuing, the Trustee shall mail to each Holder, notice of the uncured Default within thirty (30) days after
it occurs or, if later, after the Trustee is deemed to have knowledge of such Default (pursuant to this Indenture). Except in the case of a Default in payment of principal of or interest on any Note, including an accelerated payment and the failure
to make a payment on the Change of Control Payment Date pursuant to a Change of Control Offer or the Net Proceeds Payment Date pursuant to a Net Proceeds Offer, or a Default in complying with the provisions of Article Five, the Trustee may withhold
the notice if and so long as the Board of Directors, the executive committee, or a trust committee of directors or Responsible Officers, of the Trustee in good faith determines that withholding the notice is in the interests of the Holders. 

SECTION 7.06 Reports by Trustee to Holders. 

Within sixty (60) days after each June 1, beginning with June 1, 2016, the Trustee shall, to the extent that any of the events
described in Trust Indenture Act § 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with Trust Indenture Act § 313(a). The Trustee also shall
comply with Trust Indenture Act §§313(b), 313(c) and 313(d). 
 A copy of each report at the time of its mailing to Holders shall
be filed with the SEC and each securities exchange, if any, on which the Notes are listed. 

  
 -85- 








 The Issuer shall promptly notify the Trustee if the Notes become listed on any securities
exchange or of any delisting thereof and the Trustee shall comply with Trust Indenture Act § 313(d). 
 SECTION 7.07 Compensation and
Indemnity. 
 The Issuer shall pay to the Trustee from time to time such compensation as the Issuer and the Trustee shall from time to
time agree in writing for its services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable disbursements,
expenses and advances (including reasonable fees and expenses of counsel) incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Trustee’s
negligence, bad faith or willful misconduct. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents and counsel. 

The Issuer shall indemnify each of the Trustee or any predecessor Trustee and its agents for, and hold them harmless against, any and all
loss, damage, claims (including taxes (other than taxes based upon, measured by or determined by the income of the Trustee)), liability or expense incurred by them arising out of or in connection with the acceptance or administration of this trust
(including the reasonable costs and expenses of defending themselves against or investigating any claim or liability in connection with the exercise or performance of any of the Trustee’s rights, powers or duties hereunder), except in each of
the foregoing cases to the extent caused by any negligence, bad faith or willful misconduct on their part. The Trustee shall notify the Issuer promptly of any claim asserted against the Trustee or any of its agents for which it may seek indemnity.
The Issuer may, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), defend the claim and the Trustee shall cooperate in the defense. The Trustee and its agents subject to the claim may have separate counsel
and the Issuer shall pay the reasonable fees and expenses of such counsel; provided, however, that the Issuer will not be required to pay such fees and expenses if, subject to the approval of the Trustee (which approval shall not be
unreasonably withheld), it assumes the Trustee’s defense and there is no conflict of interest between the Issuer and the Trustee and its agents subject to the claim in connection with such defense as reasonably determined by the Trustee. The
Issuer need not pay for any settlement made without its written consent. The Issuer need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its negligence, bad faith or willful
misconduct. 
 When the Trustee incurs expenses or renders services after a Default specified in Section 6.01(6) or
Section 6.01(7) occurs, such expenses and the compensation for such services shall be paid to the extent allowed under any Bankruptcy Law. 

The Trustee shall have a lien prior to the Notes as to all property and funds held by it hereunder for any amount owing it or any predecessor
Trustee pursuant to this Section 7.07, except with respect to funds held in trust for the benefit of the Holders. 

  
 -86- 








 Notwithstanding any other provision in this Indenture, the foregoing provisions of this
Section 7.07 shall survive the satisfaction and discharge of this Indenture or the appointment of a successor Trustee. 
 SECTION 7.08
Replacement of Trustee. 
 The Trustee may resign by so notifying the Issuer at least thirty (30) days prior to the date of the
proposed resignation. The Holders of at least a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Issuer and the Trustee and may appoint a successor Trustee. The Issuer may remove the Trustee if:

 (1) the Trustee fails to comply with Section 7.10; 

(2) the Trustee is adjudged a bankrupt or an insolvent; 

(3) a receiver or other public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 

If the Trustee retires, whether by resignation or removal, or if a vacancy exists in the office of Trustee for any reason, the Issuer shall
notify each Holder of such event and shall promptly appoint a successor Trustee. Within one (1) year after the successor Trustee takes office, the Holders of at least a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Issuer. 
 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuer. Promptly after that, the retiring Trustee shall transfer, and after payment of all sums then owing to the Trustee pursuant to Section 7.07, all property held by it as Trustee to the
successor Trustee, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee with respect to the Notes under this Indenture. A successor Trustee
shall mail notice of its succession to each Holder. 
 If a successor Trustee does not take office within sixty (60) days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least ten percent (10%) in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee at the expense of the Issuer. 
 If the Trustee fails to comply with Section 7.10, any Holder may petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding the appointment of a
successor Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

 SECTION 7.09 Successor Trustee by Merger, Etc. 

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee; provided, however, that
such corporation shall be otherwise qualified and eligible under this Article Seven. 
 SECTION 7.10 Eligibility; Disqualification. 

The Trustee shall at all times satisfy the requirements of Trust Indenture Act §§ 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee
shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act § 310(b); provided, however, that there
shall be excluded from the operation of Trust Indenture Act § 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuer are outstanding, if the
requirements for such exclusion set forth in Trust Indenture Act § 310(b)(1) are met. The provisions of Trust Indenture Act § 310 shall apply to the Issuer and any other obligor of the Notes. 

SECTION 7.11 Preferential Collection of Claims Against the Issuer. 

The Trustee, in its capacity as Trustee hereunder, shall comply with Trust Indenture Act § 311(a), excluding any creditor relationship
listed in Trust Indenture Act § 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act § 311(a) to the extent indicated. 

ARTICLE EIGHT 
 DISCHARGE OF
INDENTURE; DEFEASANCE 
 SECTION 8.01 Termination of the Issuer’s Obligations. 

Except as otherwise provided in the penultimate paragraph of this Section 8.01, this Indenture and the Guarantees will be discharged and
will cease to be of further effect (except as to rights of registration of transfer or exchange of Notes, which shall survive until all Notes have been canceled) as to all outstanding Notes, when either: 

(a) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes that have been replaced or paid and Notes
for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust) have been delivered to the Trustee for cancellation; or 

(b) (1) all Notes that have not been delivered to the Trustee for cancellation either (i) have become due and payable by reason of the
mailing of a notice of redemption pursuant to Section 5 or Section 7 of the Notes, Section 4.06(i) or otherwise or (ii) will become due and payable within one year, and in each of the foregoing cases the Issuer has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust 

  
 -88- 








 
solely for the benefit of the Holders funds in Dollars or U.S. Government Obligations in amounts sufficient (without reinvestment) to pay and discharge the entire Indebtedness (including all
principal and accrued interest) on the Notes not theretofore delivered to the Trustee for cancellation to the date of maturity or redemption, 

(2) the Issuer or any Guarantor has paid or caused to be paid all other sums payable by the Issuer under this Indenture, 

(3) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the
Notes at maturity or on the date of redemption, as the case may be, and 
 (4) the Holders have a valid, perfected, exclusive
security interest in such trust. 
 In addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the
Trustee stating that all conditions precedent to satisfaction and discharge have been complied with. 
 In the case of clause (b) of
this Section 8.01, and subject to the next sentence and notwithstanding the foregoing paragraph, the Issuer’s obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 4.03 (as to legal existence of the Issuer only), 7.07, 8.05 and 8.06
shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.08. In addition, nothing in this Section 8.01 shall be deemed to discharge the obligations in Sections 7.07, 8.04(a), 8.05 or 8.06, all of
which shall survive the satisfaction and discharge of this Indenture. 
 After such delivery or irrevocable deposit, the Trustee upon
request by the Issuer shall acknowledge in writing the discharge of the Issuer’s obligations under the Notes and this Indenture except for the surviving obligations specified above. 

SECTION 8.02 Legal Defeasance and Covenant Defeasance. 

(a) The Issuer may, at its option and at any time, elect to have either Section 8.02(b) or 8.02(c) applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article Eight. 
 (b) Upon the Issuer’s exercise under Section 8.02(a) of
the option applicable to this Section 8.02(b), the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03, be deemed to have been discharged from its or their obligations with respect to
all outstanding Notes and Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding Notes and the Guarantees, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.04 and the other Sections of this Indenture
referred to in clauses (1) and (2) below, and to have satisfied all its or their other obligations under such Notes, such Guarantees and this Indenture (and the Trustee, on demand of and at the


  
 -89- 








 
expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: 

(1) the rights of Holders of outstanding Notes to receive, solely from the trust fund described in Section 8.04, and as
more fully set forth in such Section 8.04, payments in respect of the principal of, and interest on, such Notes when such payments are due; 

(2) the Issuer’s obligations with respect to such Notes under Article Two and Section 4.02; 

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s obligations in connection
therewith; and 
 (4) the provisions of this Article Eight applicable to Legal Defeasance (including Sections 8.04, 8.05 and
8.06). 
 Subject to compliance with this Article Eight, the Issuer may exercise its option under this Section 8.02(b) notwithstanding
the prior exercise of its option under Section 8.02(c). 
 (c) Upon the Issuer’s exercise under
Section 8.02(a) of the option applicable to this Section 8.02(c), the Issuer and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03, be released from each of their respective
obligations under the covenants contained in Sections 4.03 (other than with respect to the legal existence of the Issuer), 4.04, and 4.06 through 4.18, clause (iii) of Section 5.01(a) and Article Eleven with respect to the outstanding
Notes on and after the date the conditions set forth in Section 8.03 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes
shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer and the Guarantors may omit to comply with and shall have no obligation or liability in
respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision
herein or in any other document and such omission to comply shall not constitute a Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the
Issuer’s exercise under Section 8.02(a) of the option applicable to this Section 8.02(c), subject to the satisfaction of the conditions set forth in Section 8.03 hereof, clauses (3), (4), (5) and (8), and, after
the expiration of the period of ninety-one (91) days immediately following the deposit referred to in Section 8.03(1) (and so long as no Event of Default under clause (6) or (7) of Section 6.01 exists at the time of the
expiration of such period), clauses (6) and (7) of Section 6.01 shall not constitute Events of Default. 

  
 -90- 








 SECTION 8.03 Conditions to Legal Defeasance or Covenant Defeasance. 

In order to exercise either Legal Defeasance under Section 8.02(b) or Covenant Defeasance under Section 8.02(c) with respect to the
outstanding Notes: 
 (1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders,
funds in Dollars or U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without reinvestment), in the opinion of a nationally recognized firm of independent public accountants selected by the Issuer, to pay
the principal of and interest on the outstanding Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and the Issuer must specify to the Trustee whether such Notes are being defeased to such stated
date for payment or to a particular Redemption Date, as the case may be and the Holders must have a valid, perfected, exclusive security interest in such trust; 

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in
the United States reasonably acceptable to the Trustee confirming that: 
 (i) the Issuer has received from, or
there has been published by the Internal Revenue Service, a ruling, or 
 (ii) since the Issue Date, there has been a change
in the applicable U.S. federal income tax law, 
 in either case to the effect that, and based thereon this Opinion of Counsel shall confirm that, the
Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been
the case if such Legal Defeasance had not occurred; 
 (3) in the case of Covenant Defeasance, the Issuer shall have
delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant
Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the
borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing); 
 (5) the Legal
Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under (other than any such default resulting solely from the borrowing of funds to be applied to such deposit and the grant of any Lien on such
deposit in favor of the Trustee or the Holders) any Credit Agreement or any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound; 

  
 -91- 








 (6) the Issuer shall have delivered to the Trustee an Officers’ Certificate
stating that the deposit was not made by the Issuer with the intent of preferring the Holders over any other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others; and 

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, stating, in the
case of the Officers’ Certificate, that the conditions provided for in clauses (1) through (6) of this Section 8.03, as applicable, have been complied with and stating, in the case of the Opinion of Counsel, that clause
(1) (with respect to the validity and perfection of the security interest) and the conditions provided for in clause (2) or (3), as applicable, and clause (5) of this Section 8.03 have been complied with. 

Notwithstanding anything to the contrary herein, the borrowing of funds to be applied to any deposit, and the grant of any Lien securing such
borrowing, in order to effect any Legal Defeasance or Covenant Defeasance, shall not constitute a Default under this Indenture. 
 SECTION 8.04
Application of Trust Money. 
 (a) The Trustee or Paying Agent shall hold in trust all funds and U.S. Government Obligations
(including the proceeds thereof) deposited with it pursuant to this Article Eight in respect of the outstanding Notes, and shall apply the deposited funds and U.S. Government Obligations (including any proceeds thereof) in accordance with this
Indenture to the payment of the principal of and the interest on the Notes. The Trustee shall be under no obligation to invest said funds and U.S. Government Obligations (including any proceeds thereof), except as it may agree with the Issuer. 

(b) The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the funds or U.S.
Government Obligations (including any proceeds thereof) deposited pursuant to Section 8.03, or the principal and interest received in respect thereof, other than any such tax, fee or other charge which by law is for the account of the Holders
of the outstanding Notes. 
 (c) Anything in this Article Eight to the contrary notwithstanding, the Trustee shall promptly deliver or pay
to the Issuer from time to time upon the request of the Issuer any funds or and U.S. Government Obligations held by it as provided in Section 8.03 which, in the opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

SECTION 8.05 Repayment to the Issuer. 

Any funds or U.S. Government Obligations deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment
of the principal of or interest on the Notes and remaining unclaimed for two (2) years after such principal or interest has become due and payable shall be repaid to the Issuer on its request or (if then held by the Issuer) will be discharged
from such trust; and the Holders will thereafter be permitted to look only to the Issuer (unless an applicable law designates another Person) for payment thereof, and all liability of the 

  
 -92- 








 
Trustee or such Paying Agent with respect to such trust funds, and all liability of the Issuer as trustee thereof, will thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, shall at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), or mail to each Holder entitled to such funds,
notice that such money remains unclaimed and that, after a date specified therein, which will not be less than thirty (30) days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to
the Issuer. 
 SECTION 8.06 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any funds and U.S. Government Obligations in accordance with this Article Eight by reason of
any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if the funds deposited with the Trustee to effect Covenant Defeasance are
insufficient to pay the principal of, and interest on, the Notes when due, then the Issuer’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eight until
such time as the Trustee or Paying Agent is permitted to apply all such funds and U.S. Government Obligations in accordance with this Article Eight; provided, however, that if the Issuer has made any payment of interest on, or
principal of, any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the funds and U.S. Government Obligations held by the Trustee or Paying
Agent. 
 ARTICLE NINE

(d) A consent to any amendment, supplement or waiver under this Indenture by any Holder given in connection with an exchange (in the case of

(e) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail, or cause to be mailed, to
the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver. 
 SECTION 9.03 Effect on Senior Debt. 

No amendment of, or supplement or waiver to, this Indenture shall adversely affect the rights of any holder of Senior Debt or Guarantor Senior
Debt under Article Ten and Section 11.02 without the consent of such holder or its Representative. 

  
 -95- 








 SECTION 9.04 Compliance with the Trust Indenture Act. 

Every amendment to this Indenture or the Notes shall be set forth in a supplemental indenture hereto that complies with the Trust Indenture Act
as then in effect. 
 SECTION 9.05 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to
his Note or portion of his Note by notice to the Trustee or the Issuer received before the date on which the Trustee receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and
not theretofore revoked such consent) to the amendment, supplement or waiver. 
 The Issuer may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall be any date the Issuer shall select for such purpose. If a record date is fixed, then notwithstanding the last
sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or effective for more than ninety (90) days after such record date. The Issuer shall inform the Trustee in writing of the fixed record date if applicable. 

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses
(1) through (10) of Section 9.02(b), in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder’s Note; provided, however, that no such amendment, supplement or waiver shall impair or affect the right of any Holder to receive payment of principal of, and interest on, a Note, on or after the
respective due dates therefor, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder. 

SECTION 9.06 Notation on or Exchange of Notes. 

If an amendment, supplement or waiver changes the terms of a Note, the Issuer may require the Holder of the Note to deliver it to the Trustee.
The Issuer shall provide the Trustee with an appropriate notation on the Note about the changed terms and cause the Trustee to return it to the Holder at the Issuer’s expense. Alternatively, if the Issuer or the Trustee so determines, the
Issuer in exchange for the Note shall issue, and the Trustee shall authenticate, a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment,
supplement or waiver. 

  
 -96- 








 SECTION 9.07 Trustee To Sign Amendments, Etc. 

The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine; provided, however, that
the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive, and (subject to
Section 7.01) shall be fully protected in conclusively relying upon, an Opinion of Counsel and an Officers’ Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is
authorized or permitted by this Indenture. Such Opinion of Counsel shall be at the expense of the Issuer. 
 ARTICLE TEN 

SUBORDINATION OF NOTES 
 SECTION 10.01
Notes Subordinated to Senior Debt. 
 Anything herein to the contrary notwithstanding, each of the Issuer, for itself and its
successors, and each Holder, by his or her acceptance of Notes (whether upon original issue or upon transfer, assignment or exchange of Notes), agrees that the payment of all Obligations owing to the Holders in respect of the Notes is subordinated,
to the extent and in the manner provided in this Article Ten, to the prior payment in full of all Senior Debt (including all Obligations under any Credit Facility (including any Credit Agreement) and all Obligations under the Senior Notes) in cash,
whether outstanding on the Issue Date or thereafter incurred. Notwithstanding anything in this Article Ten to the contrary, payments and distributions (a) of Permitted Junior Securities and (b) made relating to the Notes from the trust
established pursuant to Article Eight shall not be so subordinated in right of payment, so long as, with respect to (b), (1) the conditions specified in Article Eight are satisfied on the date of any deposit pursuant to said trust and
(2) such payments and distributions did not violate the provisions of this Article Ten when made. 
 The Notes shall in all respects
rank pari passu in right of payment with (i) the Existing Senior Subordinated Notes and any Indebtedness of the Issuer that expressly provides that it ranks pari passu in right of payment with any of the Existing Senior
Subordinated Notes and (ii) the 2007 Convertible Notes (as in effect on the date hereof) and any Indebtedness of the Issuer that expressly provides that it ranks pari passu in right of payment with the 2007 Convertible Notes (as in
effect on the date hereof), and only Indebtedness of the Issuer which is Senior Debt shall rank senior to the Notes in accordance with the provisions set forth herein. 

This Article Ten shall constitute a continuing offer to all Persons who become holders of, or continue to hold, Senior Debt, such provisions
are made for the benefit of the holders of Senior Debt and such holders are made obligees hereunder and any one or more of them may enforce such provisions. 

The holders of Senior Debt (including Designated Senior Debt) shall have the right to rely on this Article Ten. 

  
 -97- 








 SECTION 10.02 Suspension of Payment When Senior Debt Is in Default. 

(a) If any default occurs and is continuing in the payment when due (beyond any applicable grace period), whether at maturity, upon any
redemption, by declaration or otherwise, of any principal of, interest on, unpaid drawings for letters of credit issued in respect of, or fees with respect to, any Designated Senior Debt (a “Payment Default”), then the Issuer shall
not (x) make any payment or distribution of any kind or character with respect to any Obligations on or relating to the Notes or (y) acquire any of the Notes for cash or assets or otherwise (other than, in either case, Permitted Junior
Securities). 
 (b) If any other event of default (other than a Payment Default) occurs and is continuing with respect to any Designated
Senior Debt (as such event of default is defined in the instrument creating or evidencing such Designated Senior Debt) permitting the holders of such Designated Senior Debt then outstanding to accelerate the maturity thereof (a “Non-Payment
Default”) and if the Representative for the respective issue of Designated Senior Debt (including, as applicable, the administrative agent under any Credit Facility (including any Credit Agreement)) gives written notice of the Non-Payment
Default to the Trustee stating that such notice is a payment blockage notice (a “Payment Blockage Notice”), then during the period (the “Payment Blockage Period”) beginning upon the delivery of such Payment Blockage
Notice and ending on the earliest of (1) the date on which all such Non-Payment Defaults are cured or waived, (2) one hundred seventy-nine (179) days after the date on which the applicable Payment Blockage Notice is received or
(3) the date on which the Trustee receives notice from the Representative for such Designated Senior Debt rescinding the Payment Blockage Notice (unless in each case the maturity of any Designated Senior Debt has been accelerated), the Issuer
shall not (x) make any payment of any kind or character with respect to any Obligations on or with respect to the Notes or (y) acquire any of the Notes for cash or assets or otherwise (other than, in either case, Permitted Junior
Securities). Notwithstanding anything herein to the contrary, (x) in no event will a Payment Blockage Period extend beyond one hundred seventy-nine (179) days from the date the applicable Payment Blockage Notice is received by the Trustee
and (y) no new Payment Blockage Notice may be delivered unless and until 360 days have elapsed since the effectiveness of the immediately prior Payment Blockage Notice. For all purposes of this Section 10.02(b), no Non-Payment Default
which existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior Debt shall be, or be made, the basis for the commencement of a second Payment Blockage Period by the
Representative of such Designated Senior Debt whether or not within a period of 360 consecutive days, unless such Non-Payment Default shall have been cured or waived for a period of not less than ninety (90) consecutive days. Any
subsequent action, or any breach of any financial covenants for a period ending after the date of commencement of such Payment Blockage Period that, in either case, would give rise to a Non-Payment Default pursuant to any provisions under which a
Non-Payment Default previously existed or was continuing shall constitute a new Non-Payment Default for this purpose. 
 (c) In the event
that, notwithstanding the foregoing, any payment shall be received by the Trustee or any Holder when such payment is prohibited by the foregoing provisions of this Section 10.02, such payment shall be held in trust for the benefit of, and shall
be paid over or delivered to, the holders of Senior Debt (pro rata to such holders on the basis of the respective amount of Senior Debt held by such holders) or their respective Representatives, as their respective interests may appear. The
Trustee shall be entitled to rely on information regarding amounts outstanding on the Senior Debt, if any, received from the holders of the Senior Debt (or their Representatives). 

  
 -98- 








 (d) Nothing contained in this Article Ten shall limit the right of the Trustee or the Holders of
the Notes to take any action to accelerate the maturity of the Notes pursuant to Section 6.02 or to pursue any rights or remedies hereunder; provided, however, that all Senior Debt thereafter due or declared to be due shall first
be paid in full in cash or cash equivalents before the Holders are entitled to receive any payment of any kind or character with respect to Obligations on the Notes. 

SECTION 10.03 Notes Subordinated to Prior Payment of All Senior Debt on Dissolution, Liquidation or Reorganization of the Issuer. 

(a) Upon any payment or distribution of assets of the Issuer of any kind or character, whether in cash, assets or securities, to creditors upon
any total or partial liquidation, dissolution, winding-up, assignment for the benefit of creditors or marshaling of assets and liabilities of the Issuer or in a bankruptcy, reorganization, insolvency, receivership or other similar proceeding
relating to the Issuer or its assets, whether voluntary or involuntary, all Obligations due on all Senior Debt (including interest accruing after the commencement of any bankruptcy or other like proceeding at the rate specified in any Credit
Facility (including any Credit Agreement) or in the Senior Notes, as applicable, whether or not such interest is an allowed claim in any such proceeding) shall first be paid in full in cash, or such payment duly provided for to the satisfaction of
the holders of Senior Debt, before any payment or distribution of any kind or character is made on account of any Obligations on or relating to the Notes. Upon any such dissolution, winding-up, liquidation, reorganization, receivership or similar
proceeding, any payment or distribution of assets of the Issuer of any kind or character, whether in cash, assets or securities, to which the Holders of the Notes or the Trustee under this Indenture would be entitled, except for the provisions
hereof, shall be paid by the Issuer or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders or by the Trustee under this Indenture if received by them, directly to
the holders of Senior Debt (pro rata to such holders on the basis of the respective amounts of Senior Debt held by such holders) or their respective Representatives, or to the trustee or trustees under any indenture pursuant to which any of
such Senior Debt may have been issued, as their respective interests may appear, for application to the payment of Senior Debt remaining unpaid until all such Senior Debt has been paid in full in cash after giving effect to any concurrent payment,
distribution or provision therefor to or for the holders of Senior Debt. 
 (b) To the extent any payment of Senior Debt (whether by or on
behalf of the Issuer, as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or
other similar Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then, if such payment is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar
Person, the Senior Debt or part thereof originally intended to be satisfied shall be for purpose of this Article Ten deemed to be reinstated and outstanding as if such payment had not occurred. 

  
 -99- 








 It is further agreed that any diminution (whether pursuant to court decree or otherwise,
including without limitation for any of the reasons described in the preceding sentence) of the Issuer’s obligation to make any distribution or payment pursuant to any Senior Debt, except to the extent such diminution occurs by reason of the
repayment (which has not been disgorged or returned) of such Senior Debt in cash or cash equivalents, shall have no force or effect for purposes of the subordination provisions contained in this Article Ten, with any turnover of payments as
otherwise calculated pursuant to this Article Ten to be made as if no such diminution had occurred. 
 (c) In the event that,
notwithstanding the foregoing, any payment or distribution of assets of the Issuer of any kind or character, whether in cash, assets or securities, shall be received by any Holder when such payment or distribution is prohibited by this
Section 10.03, such payment or distribution shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Debt (pro rata to such holders on the basis of the respective amount of Senior Debt held
by such holders) or their respective Representatives, or to the trustee or trustees under any indenture pursuant to which any of such Senior Debt may have been issued, as their respective interests may appear, for application to the payment of
Senior Debt remaining unpaid until all such Senior Debt has been paid in full in cash or cash equivalents, after giving effect to any concurrent payment, distribution or provision therefor to or for the holders of such Senior Debt. 

(d) The consolidation of the Issuer with, or the merger of the Issuer with or into, another Person or the liquidation or dissolution of the
Issuer following the conveyance or transfer of all or substantially all of its assets, to another Person upon the terms and conditions provided in Article Five hereof shall not be deemed a dissolution, winding-up, liquidation or reorganization for
the purposes of this Section if such other Person shall, as a part of such consolidation, merger, conveyance or transfer, assume the Issuer’s obligations hereunder in accordance with Article Five hereof. 

SECTION 10.04 Payments May Be Made on Notes. 

Nothing contained in this Article Ten or elsewhere in this Indenture shall prevent (a) the Issuer, except under the conditions described
in Sections 10.02 and 10.03, from making payments at any time for the purpose of making payments of principal of, and interest on, the Notes, or from depositing with the Trustee any moneys for such payments, or (b) in the absence of actual
knowledge by the Trustee that a given payment would be prohibited by Section 10.02 or 10.03, the application by the Trustee of any moneys deposited with it for the purpose of making such payments of principal of, and interest on, the Notes to
the Holders entitled thereto unless at least two (2) Business Days prior to the date upon which such payment would otherwise become due and payable a Responsible Officer of the Trustee shall have actually received the written notice provided
for in the first sentence of Section 10.02(b) or in Section 10.07; provided, however, that, notwithstanding the foregoing, the Holders receiving any payments made in contravention of Section 10.02 or 10.03 (and the
respective such payments) shall otherwise be subject to the provisions of Section 10.02 and Section 10.03. Notwithstanding anything to the contrary contained in this Article Ten or elsewhere in this Indenture, payments and distributions
from the funds deposited pursuant to Article Eight will be permitted to be made and will not be subject to the provisions of this Article Ten so long as such funds were deposited 

  
 -100- 








 
in accordance with the provisions of Article Eight and did not violate the provisions of this Article Ten when such funds were so deposited. The Issuer shall give prompt written notice to the
Trustee of any dissolution, winding-up, liquidation or reorganization of the Issuer, although any delay or failure to give any such notice shall have no effect on the subordination provisions contained herein. 

SECTION 10.05 Holders To Be Subrogated to Rights of Holders of Senior Debt. 

Subject to the payment in full of all Senior Debt in cash or cash equivalents, the Holders of the Notes shall be subrogated to the rights of
the holders of Senior Debt to receive payments or distributions of cash, assets or securities of the Issuer applicable to the Senior Debt until the Notes shall be paid in full; and, for the purposes of such subrogation, no such payments or
distributions to the holders of the Senior Debt by or on behalf of the Issuer, or by or on behalf of the Holders by virtue of this Article Ten, which otherwise would have been made to the Holders shall, as between the Issuer and the Holders, be
deemed to be a payment by the Issuer to or on account of the Senior Debt, it being understood that the provisions of this Article Ten are and are intended solely for the purpose of defining the relative rights of the Holders, on the one hand, and
the holders of Senior Debt, on the other hand. 
 SECTION 10.06 Obligations of the Issuer Unconditional. 

Nothing contained in this Article Ten or elsewhere in this Indenture or in the Notes is intended to or shall impair, as between the Issuer, and
the Holders, the obligation of the Issuer, which is absolute and unconditional, to pay to the Holders the principal of, and any interest on, the Notes as and when the same shall become due and payable in accordance with their terms, or is intended
to or shall affect the relative rights of the Holders and creditors of the Issuer other than the holders of the Senior Debt, nor shall anything herein or therein prevent the Holder of any Note or the Trustee on its behalf from exercising all
remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, of the holders of Senior Debt in respect of cash, assets or securities of the Issuer received upon the exercise of any such remedy. 

SECTION 10.07 Notice to Trustee. 

The Issuer shall give prompt written notice to the Trustee of any fact known to the Issuer which would prohibit the making of any payment to or
by the Trustee in respect of the Notes pursuant to the provisions of this Article Ten, although any delay or failure to give any such notice shall have no effect on the subordination provisions contained herein. Regardless of anything to the
contrary contained in this Article Ten or elsewhere in this Indenture, the Trustee shall not be charged with knowledge of the existence of any default or event of default with respect to any Senior Debt or of any other facts which would prohibit the
making of any payment to or by the Trustee unless and until the Trustee shall have received notice in writing from the Issuer, or from a holder of Senior Debt or a Representative therefor and, prior to the receipt of any such written notice, the
Trustee shall be entitled to assume (in the absence of actual knowledge to the contrary) that no such facts exist. The Trustee shall be entitled to rely on the delivery to it of any notice pursuant to this Section 10.07 to establish that such
notice has been given by a holder of Senior Debt (or a Representative thereof). 

  
 -101- 








 In the event that the Trustee determines in good faith that any evidence is required with respect
to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article Ten, the Trustee may request such Person to furnish evidence to the satisfaction of the Trustee as to the amounts of Senior
Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article Ten, and if such evidence is not furnished the Trustee
may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
 SECTION 10.08
Reliance on Judicial Order or Certificate of Liquidating Agent. 
 Upon any payment or distribution of assets of the Issuer referred
to in this Article Ten, the Trustee, subject to the provisions of Article Seven hereof, and the Holders of the Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any insolvency, bankruptcy,
receivership, dissolution, winding-up, liquidation, reorganization or similar case or proceeding is pending, or upon a certificate of the receiver, trustee in bankruptcy, liquidating trustee, assignee for the benefit of creditors, agent or other
Person making such payment or distribution, delivered to the Trustee or the Holders of the Notes, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Debt and other
Indebtedness of the Issuer, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article Ten. 

SECTION 10.09 Trustee’s Relation to Senior Debt. 

The Trustee and any agent of the Issuer or the Trustee shall be entitled to all the rights set forth in this Article Ten with respect to any
Senior Debt which may at any time be held by it in its individual or any other capacity to the same extent as any other holder of Senior Debt and nothing in this Indenture shall deprive the Trustee or any such agent of any of its rights as such
holder. 
 With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article Ten, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt. 
 Whenever a distribution is to be made or a notice given to holders or owners of Senior
Debt, the distribution may be made and the notice may be given to their Representative, if any. 
 SECTION 10.10 Subordination Rights Not Impaired
by Acts or Omissions of the Issuer or Holders of Senior Debt. 
 No right of any present or future holders of any Senior Debt to enforce
subordination as provided herein shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Issuer or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Issuer
with the terms of this Indenture, regardless of any knowledge thereof, which any such holder may have or otherwise be charged with. 

  
 -102- 








 Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Debt
may, at any time and from time to time, without the consent of or notice to the Trustee, without incurring responsibility to the Trustee or the Holders of the Notes and without impairing or releasing the subordination provided in this Article Ten or
the obligations hereunder of the Holders of the Notes to the holders of the Senior Debt, do any one or more of the following: (a) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt, or
otherwise amend or supplement in any manner Senior Debt, or any instrument evidencing the same or any agreement under which Senior Debt is outstanding; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Debt; (c) release any Person liable in any manner for the payment or collection of Senior Debt; and (d) exercise or refrain from exercising any rights against the Issuer and any other Person. 

SECTION 10.11 Holders Authorize Trustee To Effectuate Subordination of Notes. 

Each Holder of the Notes by its acceptance of them (whether upon original issue or upon transfer, assignment or exchange of Notes) authorizes
and expressly directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate, as between the holders of Senior Debt and the Holders of the Notes, the subordination provided in this Article Ten, and appoints
the Trustee its attorney-in-fact for such purposes, including, in the event of any dissolution, winding-up, liquidation or reorganization of the Issuer (whether in bankruptcy, insolvency, receivership, reorganization or similar proceedings or upon
an assignment for the benefit of credits or otherwise) tending towards liquidation of the business and assets of the Issuer, the filing of a claim for the unpaid balance of its Notes and accrued interest in the form required in those proceedings.

 If the Trustee does not file a proper claim or proof of debt in the form required in such proceeding prior to thirty (30) days
before the expiration of the time to file such claim or claims, then the holders of the Senior Debt or their Representative are or is hereby authorized to have the right to file and are or is hereby authorized to file an appropriate claim for and on
behalf of the Holders of said Notes. Nothing herein contained shall be deemed to authorize the Trustee or the holders of Senior Debt or their Representative to authorize, consent to, accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee or the holders of Senior Debt or their Representative to vote in respect of the claim of any Holder in any
such proceeding. 
 SECTION 10.12 This Article Ten Not To Prevent Events of Default. 

The failure to make a payment on account of principal of, or interest on, the Notes by reason of any provision of this Article Ten will not be
construed as preventing the occurrence of an Event of Default. 
 SECTION 10.13 Trustee’s Compensation Not Prejudiced. 

Nothing in this Article Ten will apply to amounts due to the Trustee (other than payments of Obligations owing to Holders in respect of the
Notes) pursuant to other Sections of this Indenture.

 ARTICLE ELEVEN 

GUARANTEE 
 SECTION 11.01 Unconditional
Guarantee. 
 Subject to the provisions of this Article Eleven, each of the Guarantors, jointly and severally, hereby unconditionally and
irrevocably guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the
Issuer to the Holders or the Trustee hereunder or thereunder: (a) (x) the due and punctual payment of the principal of and interest on the Notes when and as the same shall become due and payable, whether at maturity, upon redemption or
repurchase, by acceleration or otherwise, (y) the due and punctual payment of interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Notes and (z) the due and punctual payment and performance of all
other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder (including amounts due the Trustee under Section 7.07 hereof), all in accordance with the terms hereof and thereof (collectively, the “Guarantee
Obligations”); and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the due and punctual payment and performance of Guarantee Obligations in accordance with the terms of the
extension or renewal, whether at maturity, upon redemption or repurchase, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Issuer to the Holders under this
Indenture or under the Notes, for whatever reason, each Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. A Default under this Indenture or the Notes shall constitute an event of default under the
Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors under the Guarantees in the same manner and to the same extent as the obligations of the Issuer. 

Each of the Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any
judgment against the Issuer, any action to enforce the same, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each of the Guarantors hereby waives the benefit of diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenants that its
Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture (including the Guarantees). Each Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is
required by any court or otherwise to return to the Issuer or to any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or such Guarantor, any amount paid by the Issuer or such Guarantor to
the Trustee or such Holder, each Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the
other hand, (a) subject to this Article Eleven, the maturity of the obligations 

  
 -104- 








 
guaranteed hereby may be accelerated as provided in Article Six, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed
hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Guarantees. 

SECTION 11.02 Subordination of Guarantee. 

The obligations of each Guarantor under its Guarantee pursuant to this Article Eleven shall be junior and subordinated to the prior payment in
full of the Guarantor Senior Debt of such Guarantor, whether outstanding on the Issue Date or thereafter incurred, in cash on the same basis as the Notes are junior and subordinated to Senior Debt of the Issuer. For the purposes of the foregoing
sentence, the Trustee and the Holders shall have the right to receive or retain payments by any of the Guarantors only at such times as they may receive or retain payments in respect of the Notes pursuant to this Indenture, including Article Ten. In
addition to the foregoing provisions of this Section 11.02, all of the covenants, obligations and agreements contained in Article Ten (together with related definitions) shall be deemed incorporated in this Section 11.02, mutatis
mutandis, as if references to the Issuer therein are references to each Guarantor herein and references to Senior Debt therein are references to the Guarantor Senior Debt of such Guarantor herein. 

SECTION 11.03 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, foreign or state law to the extent applicable to any
Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under this Article Eleven shall be limited to the maximum amount as will, after giving
effect to all other contingent and fixed liabilities of such Guarantor (including any guarantee under any Credit Facility (including any Credit Agreement) permitted under Section 4.07(b)(1) and including such Guarantor’s guarantees of the
Issuer’s obligations under the Senior Notes, the Senior Notes Indenture, the Existing Senior Subordinated Notes and the Existing Senior Subordinated Notes Indentures) that are relevant under such laws, and after giving effect to any collections
from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article Eleven, result in the obligations of such Guarantor under its Guarantee not
constituting a fraudulent transfer or conveyance under any such applicable federal, foreign or state law. Each Guarantor that makes a payment for distribution under its Guarantee is entitled to a contribution from each other Guarantor in a pro
rata amount based on the adjusted net assets of each Guarantor. 

  
 -105- 








 SECTION 11.04 Release of a Guarantor. 

A Guarantor shall be released from its obligations under its Guarantee and this Indenture: 

(1) in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the Equity Interests of such Guarantor then held by the Issuer and the Restricted Subsidiaries; 

(2) if such Guarantor is designated as an Unrestricted Subsidiary or otherwise ceases to be a Restricted Subsidiary, in each
case in accordance with the provisions of this Indenture, upon effectiveness of such designation or when it first ceases to be a Restricted Subsidiary, respectively; or 

(3) if such Guarantor shall not guarantee any Indebtedness or other Obligation under any Credit Agreement (other than if such
Guarantor no longer guarantees any Indebtedness or other Obligation under such Credit Agreement as a result of payment under any guarantee of any such Indebtedness or other Obligation by such Guarantor); provided, however, that a
Guarantor shall not be permitted to be released from its Guarantee or the Indenture if it is an obligor with respect to any Indebtedness or other Obligation that would not, under Section 4.07, be permitted to be incurred by a Restricted
Subsidiary that is not a Guarantor. 
 The Trustee shall execute an appropriate instrument prepared by the Issuer evidencing the release of
a Guarantor from its obligations under its Guarantee and this Indenture upon receipt of a request by the Issuer or such Guarantor accompanied by an Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this
Section 11.04. 
 Nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor
with or into the Issuer (in which case such Guarantor shall no longer be a Guarantor) or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another
Guarantor. 
 SECTION 11.05 Waiver of Subrogation. 

Until this Indenture is discharged and all of the Notes are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees
not to exercise any claim or other rights which it may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement of the Issuer’s obligations under the Notes or this Indenture and such
Guarantor’s obligations under its Guarantee and this Indenture, in any such instance including any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the
Holders against the Issuer, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from the Issuer, directly or indirectly, in cash or other assets or by set-off
or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders of Notes under the Notes,
this Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of,
and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be 

  
 -106- 








 
credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor
acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.05 is knowingly made in contemplation of such benefits. 

SECTION 11.06 Immediate Payment. 

Each Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all Guarantee Obligations owing or payable to the
respective Holders upon receipt of a demand for payment therefor by the Trustee to such Guarantor in writing. 
 SECTION 11.07 No Set-Off. 

Each payment to be made by a Guarantor hereunder in respect of the Guarantee Obligations shall be payable in the currency or currencies in
which such Guarantee Obligations are denominated, and shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 

SECTION 11.08 Guarantee Obligations Absolute. 

The obligations of each Guarantor hereunder are and shall be absolute and unconditional and any monies or amounts expressed to be owing or
payable by each Guarantor hereunder which may not be recoverable from such Guarantor on the basis of a Guarantee shall be recoverable from such Guarantor as a primary obligor and principal debtor in respect thereof. 

SECTION 11.09 Guarantee Obligations Continuing. 

The obligations of each Guarantor hereunder shall be continuing and shall remain in full force and effect until all such obligations have been
paid and satisfied in full. Each Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability hereunder and under any other instrument or instruments in such form as
counsel to the Trustee may advise and as will prevent any action brought against it in respect of any default hereunder being barred by any statute of limitations now or hereafter in force and, in the event of the failure of a Guarantor so to do, it
hereby irrevocably appoints the Trustee the attorney and agent of such Guarantor to make, execute and deliver such written acknowledgment or acknowledgments or other instruments as may from time to time become necessary or advisable, in the
reasonable judgment of the Trustee on the advice of counsel, to fully maintain and keep in force the liability of such Guarantor hereunder. 

SECTION 11.10 Guarantee Obligations Not Reduced. 

The obligations of each Guarantor hereunder shall not be satisfied, reduced or discharged solely by the payment of such principal, interest,
fees and other monies or amounts as may at any time prior to discharge of this Indenture pursuant to Article Eight be or become owing or payable under or by virtue of or otherwise in connection with the Notes or this Indenture. 

  
 -107- 








 SECTION 11.11 Guarantee Obligations Reinstated. 

The obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any
payment which would otherwise have reduced the obligations of any Guarantor hereunder (whether such payment shall have been made by or on behalf of the Issuer or by or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon
the insolvency, bankruptcy, liquidation or reorganization of the Issuer or any Guarantor or otherwise, all as though such payment had not been made. If demand for, or acceleration of the time for, payment by the Issuer or any other Guarantor is
stayed upon the insolvency, bankruptcy, liquidation or reorganization of the Issuer or such Guarantor, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each Guarantor as provided herein.

 SECTION 11.12 Guarantee Obligations Not Affected. 

The obligations of each Guarantor hereunder shall not be affected, impaired or diminished in any way by any act, omission, matter or thing
whatsoever, occurring before, upon or after any demand for payment hereunder (and whether or not known or consented to by any Guarantor or any of the Holders) which, but for this provision, might constitute a whole or partial defense to a claim
against any Guarantor hereunder or might operate to release or otherwise exonerate any Guarantor from any of its obligations hereunder or otherwise affect such obligations, whether occasioned by default of any of the Holders or otherwise, including:

 (a) any limitation of status or power, disability, incapacity or other circumstance relating to the Issuer or any other Person, including
any insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, winding-up or other proceeding involving or affecting the Issuer or any other Person; 

(b) any irregularity, defect, unenforceability or invalidity in respect of any indebtedness or other obligation of the Issuer or any other
Person under this Indenture, the Notes or any other document or instrument; 
 (c) any failure of the Issuer or any other Guarantor, whether
or not without fault on its part, to perform or comply with any of the provisions of this Indenture (including any Guarantee) or the Notes, or to give notice thereof to a Guarantor; 

(d) the taking or enforcing or exercising or the refusal or neglect to take or enforce or exercise any right or remedy from or against the
Issuer or any other Person or their respective assets or the release or discharge of any such right or remedy; 
 (e) the granting of time,
renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the Issuer or any other Person; 

(f) any change in the time, manner or place of payment of, or in any other term of, any of the Notes, or any other amendment, variation,
supplement, replacement or waiver of, or any consent to departure from, any of the Notes or this Indenture, including any increase or decrease in the principal amount of or interest on any of the Notes; 

(g) any change in the ownership, control, name, objects, businesses, assets, capital structure or constitution of the Issuer or a Guarantor;


  
 -108- 








 (h) any merger or amalgamation of the Issuer or a Guarantor with any Person or Persons; 

(i) the occurrence of any change in the laws, rules, regulations or ordinances of any jurisdiction by any present or future action of any
governmental authority or court amending, varying, reducing or otherwise affecting, or purporting to amend, vary, reduce or otherwise affect, any of the Guarantee Obligations or the obligations of a Guarantor under its Guarantee; and

(a) Without in any way limiting the provisions of Section 11.01, each Guarantor hereby waives notice of acceptance hereof, notice of any
liability of any Guarantor hereunder, notice or proof of reliance by the Holders upon the obligations of any Guarantor hereunder, and diligence, presentment, demand for payment on the Issuer, protest, notice of dishonor or non-payment of any of the
Guarantee Obligations, or other notice or formalities to the Issuer or any Guarantor of any kind whatsoever. 
 (b) Each Guarantor has
independently, and without reliance on any information supplied by any Holder or the Trustee, taken whatever steps it has deemed necessary to inform itself of, and hereby assumes responsibility for taking such further steps as shall be necessary to
keep itself informed of, the financial condition and affairs of the Issuer, each other Guarantor and any other guarantor, maker or endorser of any Guarantee Obligations or any part thereof, and of all other circumstances bearing upon the risk of
nonpayment of any Guarantee Obligations or any part thereof that diligent inquiry would reveal, and each Guarantor hereby agrees that neither any Holder nor the Trustee shall have any duty to advise any Guarantor of information known to it regarding
such condition or any such circumstances. In the event any Holder or the Trustee, in its sole discretion, undertakes at any time or from time to time to provide any such information to any Guarantor, such Person shall be under no obligation to
(i) undertake any investigation not a part of its regular business routine, (ii) disclose any information that such Person, pursuant to accepted or reasonable commercial finance or banking practices, wishes to maintain confidential or
(iii) make any future disclosures of such information or any other information to such or any other Guarantor.

To Take Action Against the Issuer. 
 Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust any rights
or remedies against the Issuer or any other Person or any property of the Issuer or any other Person before the Trustee is entitled to demand payment and performance by any or all Guarantors of their liabilities and obligations under the Guarantees
or otherwise under this Indenture.

SECTION 11.20 No Waiver; Cumulative Remedies. 

No failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, remedy, power or privilege hereunder
or under this Indenture or the Notes, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or under this Indenture or the Notes preclude any other or further exercise thereof
or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges in the Guarantee and under this Indenture, the Notes and any other document or instrument between a Guarantor or the Issuer and the Trustee

 (Reverse of Note) 

6.375% Senior Subordinated Notes due 2023 

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

SECTION 1. Interest. Alere Inc., a Delaware corporation (the “Issuer”), promises to pay interest on the principal
amount of this Note at 6.375% per annum from June 24, 20152 until maturity. The Issuer will pay interest semi-annually on January 1 and July 1 of each year, or if any
such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”), commencing January 1, 20163. Interest on the Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been paid, from June 24, 20154. The Issuer shall pay interest (including post-petition interest in any proceeding under
any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand to the extent lawful at the interest rate applicable to the Notes; it shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

 SECTION 2. Method of Payment. The Issuer will pay interest on the Notes to the Persons who are registered Holders of Notes at the
close of business on the December 15 or June 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. The Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000. The Issuer shall pay principal, premium, if any, and interest on the Notes in such coin or currency of the
United States of America as at the time of payment is legal tender for payment of public and private debts. Principal, premium, if any, and interest on the Notes will be payable at the office or agency of the Issuer maintained for such purpose
except that, at the option of the Issuer, the payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the register of Holders of Notes; provided, however, that for Holders
that have given wire transfer instructions to the Issuer at least ten (10) Business Days prior to the applicable payment date, the Issuer will make all payments of principal, premium, if any, and interest by wire transfer of immediately
available funds to the accounts specified by the Holders thereof. Until otherwise designated by the Issuer, the Issuer’s office or agency in New York will be the office of the Trustee maintained for such purpose. 

SECTION 3. Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as
Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. Except as provided in the Indenture, the Issuer or any of its Subsidiaries may act in any such capacity.

 SECTION 4. Indenture and Subordination. The Issuer issued the Notes under an Indenture
dated as of May 12, 2009, as amended, supplemented and modified by a Twenty-First Supplemental Indenture dated as of June 24, 2015 (as so amended, supplemented and modified, the “Indenture”), by and among the Issuer, the
Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “Trust
Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of
the Indenture, the provisions of the Indenture shall govern and be controlling. The payment of the Notes will, to the extent set forth in the Indenture, be subordinated in right of payment to the prior payment in full in cash or cash equivalents of
all Senior Debt. 
 SECTION 5. Optional Redemption. Except as set forth in Section 6 and Section 7 hereof and
Section 4.06(i) of the Indenture, the Notes will not be redeemable at the Issuer’s option prior to July 1, 2018. On or after July 1, 2018, the Notes will be subject to redemption at any time (which may be more than once) at the
option of the Issuer, in whole or in part, upon not less than thirty (30) nor more than sixty (60) days’ notice (except that a notice issued in connection with a redemption referred to in Article Eight of the Indenture may be more
than sixty (60) days before such Redemption Date), at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon, if any, to but excluding the applicable Redemption
Date, if redeemed during the corresponding period set forth below: 
  

					
	Applicable Period	  	Redemption Price	 
	 July 1, 2018 – June 30, 2019
	  	 	104.781	% 
	 July 1, 2019 – June 30, 2020
	  	 	103.188	% 
	 July 1, 2020 – June 30, 2021
	  	 	101.594	% 
	 July 1, 2021 and thereafter
	  	 	100.000	% 

 SECTION 6. Optional Redemption with Proceeds from Equity Offerings. At any time (which may be more than
once) prior to July 1, 2018, the Issuer may redeem up to 35% of the aggregate principal amount of Notes, upon not less than thirty (30) nor more than sixty (60) days’ notice, with the net cash proceeds of one or more Qualified
Equity Offerings at a redemption price equal to 106.375% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to but excluding the applicable Redemption Date; provided, however,
that (i) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption and (ii) such redemption shall occur within ninety (90) days of the
date of the closing of any such Qualified Equity Offering. 
 SECTION 7. Make-whole Redemption. At any time (which may be more than
once) prior to July 1, 2018, the Issuer may redeem all or a part of the Notes, upon not less than thirty (30) nor more than sixty (60) days’ notice (except that a notice issued in connection with a


  
 A-5 








 
redemption referred to in Article Eight of the Indenture may be more than sixty (60) days before such Redemption Date), at a Redemption Price equal to 100% of the principal amount (or
portion thereof) of the Notes to be redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to but excluding, the applicable Redemption Date. “Applicable Premium” means, with respect to the
principal amount of any Note to be redeemed pursuant to this Section 7 on any Redemption Date, the greater of: (1) 1.0% of the principal amount (or portion thereof) of such Note to be redeemed; and (2) the excess, if any, of
(a) the present value at such Redemption Date of (i) the Redemption Price of such Note (or portion of the principal amount thereof to be redeemed) at July 1, 2018, as set forth in the table in Section 5 hereof, plus
(ii) all required interest payments due on such Note (or portion of the principal amount thereof to be redeemed) through July 1, 2018 (excluding accrued but unpaid interest to such Redemption Date), computed using a discount rate equal
to the Treasury Rate as of such Redemption Date plus 50 basis points; over (b) the then outstanding principal amount (or portion thereof) of such Note to be redeemed. “Treasury Rate” means, as of any Redemption Date, the
yield to maturity as of such Redemption Date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least
two (2) Business Days prior to such Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from such Redemption Date to July 1, 2018;
provided, however, that if the period from such Redemption Date to July 1, 2018 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will
be used. 
 SECTION 8. Notice of Redemption. Notice of redemption will be mailed by first class mail at least thirty (30) days
but not more than sixty (60) days before the applicable Redemption Date (except that a notice issued in connection with a redemption referred to in Article Eight of the Indenture may be more than sixty (60) days before such Redemption
Date) to each Holder of Notes to be redeemed at its registered address. Notes in denominations larger than $2,000 may be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the
portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after such Redemption Date
interest ceases to accrue on Notes or portions thereof called for redemption. 
 SECTION 9. Mandatory Redemption. The Issuer shall
not be required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 SECTION 10. Repurchase at Option of
Holder. Upon the occurrence of a Change of Control, and subject to certain conditions set forth in the Indenture, the Issuer will be required to offer to purchase all of the outstanding Notes at a purchase price equal to 101% of the
principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase. 
 The Issuer is, subject to
certain conditions and exceptions set forth in the Indenture, obligated to make an offer to purchase Notes at 100% of their principal amount, plus accrued and unpaid interest, if any, thereon to the date of repurchase, with certain net cash
proceeds of certain sales or other dispositions of assets in accordance with the Indenture. 

  
 A-6 








 SECTION 11. Denominations, Transfer, Exchange. The Notes are in registered form without
coupons in minimum denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer and the Registrar are not required to transfer or exchange any Note
selected for redemption. Also, the Issuer and the Registrar are not required to transfer or exchange any Notes for a period of fifteen (15) days before a selection of Notes to be redeemed. 

SECTION 12. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes. 

SECTION 13. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture and the Notes may be amended or supplemented
with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and compliance with any provision may be waived with the consent of the Holders of at least a majority in aggregate principal
amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Notes to, among other things, cure any ambiguity, defect or inconsistency in the Indenture, provide
for uncertificated Notes in addition to or in place of certificated Notes, comply with any requirements of the SEC in connection with the qualification of the Indenture under, and otherwise comply with, the Trust Indenture Act, or make any change
that does not materially adversely affect the rights of any Holder under the Indenture or the Notes. 
 SECTION 14. Defaults and
Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least twenty-five percent (25%) in principal amount of the then outstanding Notes generally may by written notice to the Issuer and the Trustee
declare all the Notes to be due and payable, whereupon the Notes shall become due and payable at the time provided in Section 6.02(a) of the Indenture. Notwithstanding the foregoing, in the case of an Event of Default arising from certain
events of bankruptcy or insolvency as set forth in the Indenture, with respect to the Issuer or any Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of at least a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal or interest, including an accelerated payment or the failure to make a payment on the Change of Control Payment Date or
the Net Proceeds Payment Date pursuant to a Net Proceeds Offer, or a Default in complying with the provisions of Article Five of the Indenture) if it determines in good faith that withholding notice is in their interest. The Holders of at least a
majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its consequences under the Indenture except a continuing Default in the
payment of interest on, or the principal of, or the premium, if any, on, the Notes.

 SECTION 15. Restrictive Covenants. The Indenture contains certain covenants that, among
other things, limit the ability of the Issuer and its Restricted Subsidiaries to make restricted payments, to incur indebtedness, to create liens, to sell assets, to permit restrictions on dividends and other payments by Restricted Subsidiaries of
the Issuer, to consolidate, merge or sell all or substantially all of its assets or to engage in transactions with affiliates. The limitations are subject to a number of important qualifications and exceptions. The Issuer must annually report to the
Trustee on compliance with such limitations and other provisions in the Indenture. 
 SECTION 16. No Recourse Against Others. No
director, officer, employee, incorporator, stockholder, member or manager of the Issuer or any Guarantor shall have any liability for any obligations of the Issuer or any Guarantor under the Indenture (including the Guarantees) or the Notes for any
claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and
the Guarantees. 
 SECTION 17. Guarantees. This Note will be entitled to the benefits of certain Guarantees made for the benefit of
the Holders by the Guarantors pursuant to the Indenture. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantors, the Trustee and the Holders.

 SECTION 18. Trustee Dealings with the Issuer. Subject to certain terms, the Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee. 

SECTION 19. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent. 
 SECTION 20. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such
as: TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

SECTION 21. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures, the Issuer has caused CUSIP or ISIN numbers to be printed on the Notes and the Trustee may use CUSIP or ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers
either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

SECTION 22. Governing Law. This Note shall be governed by, and construed in accordance with, the laws of the State of New York, but
without giving effect to applicable principles of conflicts of laws to the extent that the application of the laws of another jurisdiction would be required thereby. 

The Issuer will furnish to any Holder upon written request and without charge a copy of the Indenture.

similar to such provisions of ERISA or the Code (“Similar Laws”), or of an entity whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement, or (B) the acquisition and holding
