 THE
NOTES 
 Section 3.01 Form and Dating. 
 (a) General. The Notes and the Trustee’s certificate of authentication will 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. Each Note will be dated the date of its authentication. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of the Indenture and the Company
and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this
Supplemental Indenture, the provisions of this Supplemental Indenture shall govern and be controlling. 
 (b) Global
Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in
definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent
such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes
represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, transfers and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount
of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 3.06 hereof. 

Section 3.02 Execution and Authentication. 
 At least one Officer must sign the Notes for the Company by manual, facsimile or electronically transmitted signature. 
 If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid. 

A Note will not be entitled to any benefit under the Indenture or be valid until authenticated by the manual signature of the Trustee.
The signature will be conclusive evidence that the Note has been authenticated under the Indenture. 
 The Trustee
will, upon receipt of a written order of the Company signed by two Officers (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under the Indenture, including any
Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in
Section 3.07 hereof.  

  
 27 








 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in the 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 Company or an Affiliate of the Company. 
 Section 3.03 Registrar
and Paying Agent. 
 The Company will maintain an office or agency where Notes may be presented for registration of transfer
or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may
appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent
or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to the Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the
Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 
 The Company initially
appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. 
 The
Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes. 

Section 3.04 Paying Agent to Hold Money in Trust. 
 The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent
for the payment of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee
may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon
payment over to the Trustee and upon accounting for any funds disbursed, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will
segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Each Paying Agent shall otherwise comply with TIA §317(b). Upon any bankruptcy or reorganization proceedings relating to the
Company under applicable Bankruptcy Law, the Trustee will serve as Paying Agent for the Notes. 
 Section 3.05 Holder Lists.

 The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names
and addresses of all Holders and shall otherwise comply with TIA §312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least five Business Days before 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 the Holders, and the Company shall otherwise comply with TIA §312(a).

 Section 3.06 Transfer and Exchange. 

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee
of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All beneficial interests in
the Global Notes will be exchanged by the Company for Definitive Notes if: 
 (1) the Company delivers to the
Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the
Company within 90 days after the date of such notice from the Depositary; 
 (2) the Company
in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or 
 (3) there has occurred and is continuing an Event of Default with respect to the Notes, and the Depositary requests the issuance of Definitive Notes. 

In connection with the exchange of all the beneficial interests in a Global Note to beneficial owners pursuant to this
Section 3.06(a), the Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange
for its beneficial interests in the Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 3.07 and 3.10 hereof.
A Global Note may not be exchanged for another Note other than as provided in this Section 3.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 3.06(b) hereof. 

Neither the Company nor the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made
on account of, Notes by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to the Notes. Neither the Company nor the Trustee shall be liable for any delay by the related Holder of the Global Note or
the Depositary in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from such Holder or the Depositary for all purposes (including with respect to the registration
and delivery, and the respective principal amounts, of the Definitive Notes to be issued). 
 (b) Transfer and Exchange of
Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of the Indenture and the Applicable Procedures. Beneficial
interests in any Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in a Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers
described in this Section 3.06(b). 
 (c) Transfer and Exchange of Definitive Notes for Beneficial Interests. Other
than following an exchange of beneficial interest in a Global Note for Definitive Notes as contemplated by Section 3.06(a)(2), a Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such
Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and
increase or cause to be increased the aggregate principal amount of one of the Global Notes. 

  
 29 








 (d) Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a
Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 3.06(d), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the
requesting Holder must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly
authorized in writing. A Holder of Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Definitive Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Definitive
Note pursuant to the instructions from the Holder thereof. 
 (e) Legends. Each Global Note will bear a legend in
substantially the following form: 
 “THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS
NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 3.06 OF THE
INDENTURE, (2) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 3.06(a) OF THE INDENTURE, (3) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 3.11 OF THE INDENTURE AND
(4) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY IN ACCORDANCE WITH THE INDENTURE. 
 UNLESS AND UNTIL IT IS EXCHANGED IN
WHOLE OR IN PART FOR NOTES IN DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE
DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK)
(“DTC”), TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.” 
 (f) Cancellation and/or Adjustment of Global
Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be
returned to or retained and canceled by the Trustee in accordance with Section 3.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery
thereof in the form of a beneficial interest in another Global Note, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at
the direction of the Trustee to reflect such reduction, and such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such
increase. 

  
 30 








 (g) General Provisions Relating to Transfers and Exchanges. 

(1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global
Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 3.02 hereof or at the Registrar’s request. 
 (2) No service charge will be imposed by the Company, the Trustee or the Registrar on a holder of a beneficial interest in a Global Note or on a Holder of a Definitive Note for any registration of
transfer or exchange, but the Company 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 taxes or similar governmental charge payable upon
exchange or transfer pursuant to Sections 3.10, 4.06, 4.09, 5.10, 5.15 and 10.05 hereof). 
 (3) All Global Notes
and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture, as the
Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (4) Neither the
Registrar nor the Company will be required: 
 (A) to issue, to register the transfer of or to exchange any Notes
during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 4.02 hereof and ending at the close of business on the day of selection; or 

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed
portion of any Note being redeemed in part. 
 (5) Prior to due presentment for the registration of a transfer of
any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, premium, if any, interest, if any, on, or
Additional Amounts, if any, on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. Members of, or participants in, the Depositary (“Agent Members”)
shall have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee or the Custodian as its custodian, or under such Global Note, and the Depositary may be treated by the Company, the
Trustee or the Custodian and any agent of the Company, the Trustee or the Custodian as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered holder of a Global Note may grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder of Notes is entitled to take under the Indenture or the Notes and (ii) nothing
herein shall prevent the Company, the Trustee or the Custodian, or any agent of the Company, the Trustee or the Custodian, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or shall impair, as
between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Note. 

  
 31 








 (6) The Trustee will authenticate Global Notes and Definitive Notes in
accordance with the provisions of Section 3.02 hereof. 
 (7) All certifications, certificates and Opinions
of Counsel required to be submitted to the Registrar pursuant to this Section 3.06 to effect a registration of transfer or exchange may be submitted by facsimile or electronic image scan. 

Section 3.07 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Company will issue and the
Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the
judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

 Every replacement Note is an additional obligation of the Company and will be entitled to all of the benefits of the
Indenture equally and proportionately with all other Notes duly issued hereunder. 
 Section 3.08 Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it
for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 3.08 as not outstanding. Except as set forth in Section 3.09 hereof,
a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 4.07(a)
hereof. 
 If a Note is replaced pursuant to Section 3.07 hereof, it ceases to be outstanding unless the Trustee receives
proof satisfactory to it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is
considered paid under Section 5.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 
 If the
Paying Agent (other than the Company or a Subsidiary thereof) holds, as of 11:00 a.m., Eastern time, on a redemption date, a Purchase Date, the Business Day following a Change of Control Purchase Date, or the maturity date, money sufficient to pay
Notes payable on that date, then on and after such redemption date, Purchase Date, Change of Control Purchase Date or maturity date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 

Section 3.09 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in
relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 

  
 32 








 Section 3.10 Temporary Notes. 

Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication
Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee.
Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of the Indenture. 

Section 3.11 Cancellation. 
 The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange
or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act).
Certification of the destruction of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 

Section 3.12 Defaulted Interest. 
 If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the
Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 5.01 hereof. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on
each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to Holders a notice that
states the special record date, the related payment date and the amount of such interest to be paid. 
 Section 3.13 CUSIP Numbers.

 The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall
use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify
the Trustee in writing of any change in the “CUSIP” numbers. 
 Section 3.14 Issuance of Additional Notes. 

After the Issue Date, the Company shall be entitled, subject to its compliance with Section 5.09, to issue Additional Notes under
the Indenture. With respect to any Additional Notes, the Company shall set forth in an Officers’ Certificate, a copy of which, together with a resolution of the Company’s Board of Directors authorizing the issuance of such Additional
Notes, shall be delivered to the Trustee, the following information: 
 (a) the aggregate principal amount of such Additional
Notes to be authenticated and delivered pursuant to the Indenture; and 

  
 33 








 (b) the issue date and the CUSIP number of such Additional Notes. 

ARTICLE 4 

REDEMPTION AND PREPAYMENT 

Section 4.01 Notices to Trustee. 
 If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 4.07 hereof, it must furnish to the Trustee, at least 30 days but not more than 60 days before a
redemption date, an Officers’ Certificate setting forth: 
 (1) the clause of this Supplemental Indenture
pursuant to which the redemption shall occur; 
 (2) the redemption date; 

(3) the principal amount of Notes to be redeemed; and 

(4) the redemption price. 
 Section 4.02 Selection of Notes to Be Redeemed or Purchased. 
 If less
than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 3
hereof, based on a method as the Depositary or its nominee or successor may require or, where the nominee or the successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate),
unless otherwise required by law or applicable stock exchange or depositary requirements, not less than 30 nor more than 60 days prior to the redemption or purchase date from the outstanding Notes not previously called for redemption or purchase.

 The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of
any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. No Notes of $2,000 or less in principal amount can be redeemed or purchased in part. Notes and portions of Notes selected will be in
amounts of $2,000 or whole multiples of $1,000 in excess thereof, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. Except as
provided in the preceding sentence, provisions of the Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. 
 Section 4.03 Notice of Redemption. 
 At least 30 days but not more
than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed
more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Articles 9 or 12 hereof. 

  
 34 








 The notice will identify the Notes to be redeemed and will state: 

(1) the redemption date; 
 (2) the redemption price (or the method of calculating or determining the redemption price); 
 (3) 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 upon surrender of such Note, a new Note or Notes in principal
amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 
 (4) the name and
address of the Paying Agent; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent to
collect the redemption price; 
 (6) that, unless the Company defaults in making such redemption payment,
interest on Notes (or any portion thereof) called for redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph of the Notes and/or Section of this Supplemental Indenture pursuant to which the Notes called for redemption are being redeemed; and 

(8) the CUSIP number, if any, relating to the Notes and that no representation is made as to the correctness or accuracy
of the CUSIP number, if any, listed in such notice or printed on the Notes. 
 At the Company’s request, the Trustee will
give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 15 days prior to the date of giving notice of redemption (unless a shorter period is
satisfactory to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

Section 4.04 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 4.03 hereof, Notes called for redemption become irrevocably due and payable (subject to the provisions of the next succeeding sentence)
on the redemption date at the redemption price. Except as provided in Section 4.07(d), notice of any redemption, including, without limitation, pursuant to Section 4.07(a) hereof upon an Equity Offering, may, at the Company’s
discretion, be subject to one or more conditions precedent, including, but not limited to, the completion of a related Equity Offering. 

Section 4.05 Deposit of Redemption or Purchase Price. 
 By 11:00 a.m., Eastern time, on any redemption date, any Purchase Date or the Business Day following any Change of Control Purchase Date, the Company will deposit with the Trustee or with the Paying Agent
money sufficient to pay the redemption or purchase price of and accrued interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee
or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of and accrued interest, if any, on all Notes to be redeemed or purchased. 

  
 35 








 If the Company complies with the provisions of the preceding paragraph, on and after the
redemption date, Purchase Date or Change of Control Purchase Date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchased, whether or not such Notes are presented for payment, and the Holders of such
Notes shall have no further rights with respect to such Notes except for the right to receive the redemption or purchase price of, accrued interest, if any, and Additional Amounts, if any, on such Notes upon surrender of such Notes. If a Note is
redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such
record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from
the redemption date, Purchase Date or Change of Control Purchase Date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 5.01
hereof. 
 Section 4.06 Notes Redeemed or Purchased in Part. 

Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the
Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. 
 Section 4.07 Optional Redemption.

accrued and unpaid interest, if any, to the date of redemption (subject to the rights of Holders on the relevant record date to receive interest on the relevant interest payment date), with the net cash proceeds of one or more Equity Offerings by
the Company; provided that: 
 (1) at least 65% of the aggregate principal amount of the Initial Notes

	  	 	100.000	% 

 (e) The Company may redeem the Notes, in whole but not in part, at its discretion at any time upon giving
not less than 30 nor more than 60 days’ prior notice to the Holders (which notice will be irrevocable and given in accordance with Section 4.03 hereof), at a redemption price equal to 100% of the principal amount thereof, together with
accrued and unpaid interest, if any, to the date fixed by the Company for redemption (a “Tax Redemption Date”) and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the
redemption or otherwise (subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date and Additional Amounts, if any, in respect thereof), if on the next date on which any amount would be
payable in respect of the Notes, the Company is or would be required to pay Additional Amounts, and the Company cannot avoid any such payment obligation by taking reasonable measures available (including, for the avoidance of doubt, the appointment
of a new Paying Agent), and the requirement arises as a result of: 
 (1) any change in, or amendment to, the
laws (or any regulations or rulings promulgated thereunder) of the relevant Tax Jurisdiction affecting taxation, which change or amendment has not been publicly announced before and which becomes effective on or after the date on which the Tax
Jurisdiction imposing the relevant withholding or deduction became the applicable Tax Jurisdiction under the Indenture; or 
 (2) any change in, or amendment to, the existing official position regarding the application, administration or interpretation of such laws, regulations or rulings (including a holding, judgment or order
by a court of competent jurisdiction or a change in published practice), which change, amendment, application or interpretation has not been publicly announced before and becomes effective on or after the date on which the Tax Jurisdiction imposing
the relevant withholding or deduction became the applicable Tax Jurisdiction under the Indenture). 
 In the case of Additional
Amounts required to be paid as a result of the Company’s conducting business other than in the place of its organization, such amendment or change must be announced and become effective on or after the date in which the Company begins to
conduct business giving rise to the relevant withholding or deduction. 
 The Company will not give any such notice of
redemption earlier than 60 days prior to the earliest date on which it would be obligated to make such payment or withholding if a payment in respect of the Notes were then due, and at the time such notice is given, the obligation to pay Additional
Amounts must remain in effect. Prior to the publication or, where relevant, mailing of any notice of redemption of the Notes pursuant to the foregoing, the Company will deliver to the Trustee an opinion of independent tax counsel, the choice of such
counsel to be subject to the prior written approval of the Trustee (such approval not to be unreasonably withheld) to the effect that there has been such change or amendment 

  
 37 








 
which would entitle the Company to redeem the Notes hereunder. In addition, before the Company publishes or mails notice of redemption of the Notes, it will deliver to the Trustee an
Officers’ Certificate to the effect that it cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. 
 The Trustee will accept, and will be entitled to rely solely on, such Officers’ Certificate and Opinion of Counsel as conclusive proof of the existence and satisfaction of the conditions precedent as
described in the immediately preceding paragraph, in which event such satisfaction of the conditions precedent will be conclusive and binding on the Holders. 
 For the avoidance of doubt, the implementation of European Council Directive 2003/48/EC on any other directive implementing the conclusions of the ECOFIN Council meeting of 26 and 27 November 2000 on
the taxation of savings income or any law implementing or complying with or introduced in order to conform to, such directive will not be a change or amendment for such purposes. 

(f) Any redemption pursuant to this Section 4.07 shall be made pursuant to the provisions of Sections 4.01 through 4.06 hereof.

 Section 4.08 Mandatory Redemption. 
 The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 Section 4.09 Offer to Purchase by Application of Excess Proceeds. 
 In
the event that, pursuant to Section 5.10 hereof, the Company is required to commence an offer (an “Asset Sale Offer”) to all Holders to purchase Notes and all holders of other Indebtedness that is pari passu with the
Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, it will follow the procedures specified below. 

The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business
Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will
apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness as specified in Section 5.10(d) or, if less than the Offer Amount has been tendered, all Notes and other
Indebtedness tendered and not withdrawn in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
 If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will 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 will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to each of the Holders, with a copy to the Trustee. The notice will contain all instructions and
materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state: 

(1) that the Asset Sale Offer is being made pursuant to this Section 4.09 and Section 5.10 hereof and the length
of time the Asset Sale Offer will remain open; 

  
 38 








 (2) the Offer Amount, the purchase price and the Purchase Date; 

(3) that any Note not properly tendered or accepted for payment will continue to accrue interest; 

(4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale
Offer will cease to accrue interest on and after the Purchase Date; 
 (5) that Holders electing to have Notes
purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a
Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three Business Days before the Purchase Date; 
 (6) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a
facsimile transmission or letter 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 and other pari passu Indebtedness tendered in (or required to
be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis (except that any Notes represented in
global form will be selected by such method as the Depositary or its nominee or successor may require or, where the nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and
appropriate), based on the principal amount of Notes and such other pari passu Indebtedness tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations
of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and 
 (8) that Holders whose
Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal amount
or an integral multiple of $1,000 in excess thereof. 
 On or before the Purchase Date, the Company will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the principal amount of Notes or portions thereof required to be purchased pursuant to this Section 4.09, and will deliver or cause to be delivered to the Trustee the Notes
properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.09. The Company, the Depositary or the Paying
Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the
Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder,


  
 39 








 
in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company
will publicly announce the results of the Asset Sale Offer on the Purchase Date. 
 The Company will comply with the
requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those requirements, laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale
Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.09 or Section 5.10 hereof, the Company will comply with the applicable securities laws and regulations and will
not be deemed to have breached its obligations under this Section 4.09 or Section 5.10 hereof by virtue of such compliance. 
 Other than as specifically provided in this Section 4.09 or Section 5.10, any purchase pursuant to this Section 4.09 shall be made pursuant to the provisions of Sections 4.02, 4.05 and 4.06
hereof. 
 Section 4.10 Purchase of Notes. 
 The Company and any Affiliate of the Company may at any time purchase or otherwise acquire Notes in the open market or by private agreement. Any such acquisition shall not operate as or be deemed for any
purpose to be a redemption of the indebtedness represented by such Notes. Any Notes purchased or acquired by the Company may be delivered to the Trustee and, upon such delivery, the indebtedness represented thereby shall be deemed to be satisfied.
Section 3.11 shall apply to all Notes so delivered. 
 ARTICLE 5 

COVENANTS 
 Section 5.01
Payment of Notes. 
 The Company will pay or cause to be paid the principal of, and premium, if any, and interest, if
any, on, the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest, if any, will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of
11:00 a.m., Eastern Time, on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due. 

The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a
rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without
regard to any applicable grace period), at the same rate to the extent lawful. 
 Section 5.02 Maintenance of Office or Agency.

 The Company will maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of
the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be
served. The Company 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 Company fails to maintain any such required office or agency or fails 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. 

  
 40 








 The Company 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; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to
maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company 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. 
 Unless otherwise designated by the Company by written notice to the Trustee, such office or agency shall be
the office of the Trustee in The City of New York, which on the date hereof is located at 45 Broadway, 14th Floor, New York, New York 10006. 

Section 5.03 Reports. 
 (a) Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Company will furnish to the Trustee and, upon its prior request, to any Holder (or, to the
extent permitted by the SEC, file with the SEC for public availability), within the time periods specified in the SEC’s rules and regulations, taking into account any extension of time, deemed filing date or safe harbor contemplated or provided
for by Rule 12b-25, Rule 13a-11(c) and Rule 15d-11(c) under the Exchange Act or successor provisions: 
 (1) all
quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file such reports, 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 Company’s certified independent accountants; and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file
such reports. 
 The Company will be deemed to have furnished such reports to the Trustee and the Holders if it has filed such
reports with the SEC using the EDGAR filing system and such reports are publicly available. 
 All such reports will be prepared
in all material respects in accordance with all of the rules and regulations applicable to such reports. The Company will at all times comply with TIA §314(a). 
 If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company will nevertheless continue filing the reports specified in the
preceding paragraphs of this Section 5.03(a) with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company will not take any action for the purpose of causing the SEC not to accept any such
filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraphs of this Section 5.03(a) on its website within the time
periods that would apply if the Company were required to file those reports with the SEC. 
 Delivery of such reports to the
Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s
compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 

  
 41 








 (b) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, and
such Unrestricted Subsidiaries’ aggregate Specified Consolidated Tangible Assets as of the end of the most recently completed fiscal year exceeds an amount equal to 5% of the Company’s Consolidated Tangible Assets, then the quarterly and
annual financial information required by Section 5.03(a) will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial
Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

 Section 5.04 Compliance Certificate. 
 (a) The Company and each Guarantor (if any and to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 120 days after the end of each fiscal year ending after
the Issue Date, a certificate signed by the principal executive officer, principal financial officer or principal accounting officer of the Company or such Guarantor, which need not constitute an Officers’ Certificate, complying with TIA §
314(a)(4) and stating that a review of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has
kept, observed, performed and fulfilled its obligations under the Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each
and every covenant contained in the Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of the Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or
Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which
payments on account of the principal of, premium, if any, on or interest if any, on, the Notes are prohibited (or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto).

 (b) So long as any of the Notes are outstanding, the Company will deliver to the Trustee, as soon as practicable, but in no
event more than five Business Days, after any Officer of the Company becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to
take with respect thereto. 
 Section 5.05 Taxes. 
 The Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by
appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders. 
 Section 5.06
Stay, Extension and Usury Laws. 
 Each of the Company and the Guarantors, if any, covenants (to the extent that it may
lawfully do so) 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, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the
covenants or the performance of the Indenture; and each of the Company and the 

  
 42 








 
Guarantors, if any (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, 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 has been enacted. 
 Section 5.07 Restricted Payments. 
 (a) The Company will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly: 
 (I) declare or pay any dividend or
make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or
any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests
(other than Disqualified Stock) of the Company and other than dividends or distributions payable to the Company or a Restricted Subsidiary of the Company); 
 (II) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or
any direct or indirect parent of the Company; 
 (III) make any principal payment on or with respect to, or

Indebtedness between or among the Company and any of its Restricted Subsidiaries, (ii) the purchase, redemption, defeasance, repurchase or other acquisition of Indebtedness of the Company or any Guarantor that is contractually subordinated in
right of payment to the Notes or to any Note Guarantee purchased, redeemed, defeased or otherwise acquired in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year after the
date of purchase, repurchase, redemption, defeasance or acquisition, and (iii) any payment of principal at the Stated Maturity thereof); or 
 (IV) make any Restricted Investment (all such payments and other actions set forth in these clauses (I) through (IV) above being collectively referred to as “Restricted Payments”),

 unless, at the time of and immediately after giving effect to such Restricted Payment: 

(1) no Default (other than a Reporting Default) or Event of Default has occurred and is continuing or would occur as a
consequence of such Restricted Payment; 
 (2) the Company would, at the time of such Restricted Payment and
after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage
Ratio test set forth in Section 5.09(a) hereof; and

sum, without duplication, of: 
 (A) 50% of the Consolidated Net Income of the Company for the period (taken as
one accounting period) beginning on January 1, 2012 and ending on the last day of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such
Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus  
 (B) 100% of the
aggregate net cash proceeds and the Fair Market Value of (i) marketable securities (other than marketable securities of the Company or a Subsidiary of the Company), (ii) Equity Interests of a Person (other than the Company or any

capital or from the issue or sale of Qualifying Equity Interests or (y) from the issue or sale of convertible or exchangeable Disqualified Stock of the Company or convertible or exchangeable debt securities of the Company, in each case that
have been converted into or exchanged for Qualifying Equity Interests of the Company (other than net cash proceeds received from an issuance or sale of Qualifying Equity Interests, convertible or exchangeable Disqualified Stock or debt securities to
a Subsidiary of the Company) or (z) upon the exercise of any options, warrants or rights to purchase Qualifying Equity Interests; plus  
 (C) with respect to any Restricted Investments made by the Company or any of its Restricted Subsidiaries in any Person after the Issue Date:

 (D) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the
Company’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to the Issue Date of any such Indebtedness of the Company or its Restricted Subsidiaries convertible or exchangeable for Equity
Interests (other than Disqualified Stock) of the Company (less the amount of any cash, or the Fair Market Value of any other property (other than such Equity Interests), distributed by the Company upon such conversion or exchange), together with the

Company or any Subsidiary); plus 

  
 44 








 (E) to the extent that any Unrestricted Subsidiary of the Company designated
as such after the Issue Date is redesignated as a Restricted Subsidiary pursuant to the terms of the Indenture or is merged or consolidated with or into, or transfers or otherwise disposes of all or substantially all of its properties or assets to

Unrestricted Subsidiary after the Issue Date. 
 (b) The provisions of Section 5.07(a) hereof will not prohibit:

 (1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the

being deemed substantially concurrent if such Restricted Payment occurs not more than 90 days after such sale or contribution; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will not
be considered to be net proceeds of Qualifying Equity Interests for purposes of Section 5.07(a)(3)(B) hereof and will not be considered to be net cash proceeds from an Equity Offering for purposes of Section 4.07(a) hereof; 

(3) the payment of any dividend (or, in the case of any partnership or limited liability company, any similar

repurchase, redemption, defeasance, acquisition or retirement occurs not more than 90 days after such incurrence; 
 (5) so long as no Default (other than a Reporting Default) or Event of Default has occurred and is continuing, the repurchase, redemption or other acquisition or retirement for value of any Equity
Interests of the Company or any Restricted Subsidiary of the Company held by any current or former officer, director or employee of the Company or any of its Restricted Subsidiaries pursuant to any equity subscription agreement, stock option

 45 








 
any calendar year (with any portion of such $5.0 million amount that is unused in any calendar year to be carried forward to successive calendar years and added to such amount) plus, to
the extent not previously applied or included, (i) the net cash proceeds received by the Company or any of its Restricted Subsidiaries from sales of Equity Interests (other than Disqualified Stock) to employees or directors of the Company or

(ii) the net cash proceeds of key man life insurance policies received by the Company or any of its Restricted Subsidiaries after the Issue Date;

extent permitted by the Indenture) has made the Change of Control Offer or Asset Sale Offer, as applicable, with respect to the Notes as a result of such Change of Control or Asset Sale, as applicable, and has completed the repurchase or redemption
of all Notes validly tendered for payment and not withdrawn in connection with such Change of Control Offer or Asset Sale Offer, as applicable; 
 (9) so long as no Event of Default has occurred and is continuing, the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the

 46 








 For purposes of determining compliance with this Section 5.07, in the event that a
Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in Section 5.07(b) or as a Permitted Investment, the Company will be permitted to divide or classify (or later divide, classify or
reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 5.07. 
 The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the
Company or any Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued by this Section 5.07 will be determined, in the case of amounts under
$75.0 million, by an Officer of the Company and, in the case of amounts greater than or equal to $75.0 million, by the Board of Directors of the Company whose resolution with respect thereto will be delivered to the Trustee. 

Section 5.08 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or
become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to: 
 (1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries or pay any indebtedness owed to the Company or any of its Restricted
Subsidiaries; 
 (2) make loans or advances to the Company or any of its Restricted Subsidiaries; or 

(3) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

 (b) The restrictions in Section 5.08(a) hereof will not apply to encumbrances or restrictions existing under or by
reason of: 
 (1) agreements (including agreements governing Existing Indebtedness and Credit Facilities) as in
effect on the Issue Date and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements,
refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date, as determined by the Company in
its reasonable and good faith judgment; 
 (2) the Indenture, the Notes and the Note Guarantees; 

(3) agreements governing other Indebtedness permitted to be incurred under Section 5.09 hereof and any amendments,
restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the restrictions therein are not materially more restrictive, taken as a whole, than those contained in
(i) the Indenture, the Notes and the Note Guarantees or (ii) agreements governing Indebtedness in effect on the Issue Date, in each case, as determined by the Company in its reasonable and good faith judgment; 

  
 47 








 (4) applicable law, rule, regulation or order; 

(5) any agreement or instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its
Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the
Indenture to be incurred; 
 (6) customary non-assignment provisions in contracts and licenses entered into in
the ordinary course of business; 
 (7) purchase money obligations for property acquired in the ordinary course
of business and Capital Lease Obligations that impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 5.08(a) hereof; 

(8) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that
Restricted Subsidiary pending its sale or other disposition; 
 (9) Permitted Refinancing Indebtedness;
provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being
refinanced as determined by the Company in its reasonable and good faith judgment; 
 (10) Liens permitted to be
incurred under the provisions of Section 5.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens; 
 (11) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar
agreements (including agreements entered into in connection with a Restricted Investment) entered into (i) in the ordinary course of business or (ii) with the approval of the Company’s Board of Directors, which limitation is
applicable only to the assets that are the subject of such agreements; 
 (12) restrictions on cash or other
deposits or net worth imposed by customers or required by insurance, surety or bonding companies, in each case under contracts entered into in the ordinary course of business; and 

(13) encumbrances or restrictions with respect to property under a charter, lease or other agreement that has been entered
into in the ordinary course for the employment, charter or other hire of such property. 
 Section 5.09 Incurrence of Indebtedness and
Issuance of Preferred Stock. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and
the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) or
issue Disqualified Stock if the Fixed Charge Coverage Ratio 

  
 48 








 
for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is
incurred or such Disqualified Stock is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been
incurred or the Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. 
 (b) The
provisions of Section 5.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any Disqualified Stock or any preferred securities described below (collectively, “Permitted
Debt”): 
 (1) the incurrence by the Company and any of its Restricted Subsidiaries of Indebtedness and
letters of credit under Credit Facilities in an aggregate principal amount at any one time outstanding under this Section 5.09(b)(1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the
Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (i) $1,100.0 million and (ii) the sum of $550.0 million and 25% of the Company’s Consolidated Tangible Assets; 

(2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness; 

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes and the related Note
Guarantees to be issued on the Issue Date; 
 (4) the incurrence by the Company or any of its Restricted
Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction,
installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund,
refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of (i) $75.0 million and (ii) 3% of the Company’s Consolidated Tangible Assets at any time outstanding;

 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness
in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge, in whole or in part, any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company that was permitted
by the Indenture to be incurred under Section 5.09(a) hereof or clauses (2), (3), (4), (5), (10) or (13) of this Section 5.09(b); 
 (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

 (A) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a
Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the applicable Note Guarantee, in the case of a
Guarantor; and 

  
 49 








 (B) (i) any subsequent issuance or transfer of Equity Interests that results
in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company or (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary
of the Company will be deemed, in each case, to constitute an incurrence (as of the date of such issuance, sale or transfer) of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause
(6); 
 (7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its
Restricted Subsidiaries of shares of preferred stock; provided, however, that: 
 (A) any subsequent
issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and 

(B) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted
Subsidiary of the Company, 
 will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that
was not permitted by this clause (7); 
 (8) the incurrence by the Company or any of its Restricted Subsidiaries
of Hedging Obligations in the ordinary course of business and not for speculative purposes; 
 (9) the guarantee
by the Company or any Restricted Subsidiary of the Company of Indebtedness of the Company or a Restricted Subsidiary of the Company, to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this
Section 5.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness
guaranteed; 
 (10) Permitted Acquisition Indebtedness; 

(11) Indebtedness in respect of workers’ compensation claims, public liability insurance, unemployment insurance,
property, casualty or liability insurance, self-insurance obligations or completion, performance, bid performance, appeal or surety bonds in the ordinary course of business, including guarantees or obligations with respect to letters of credit
supporting such workers’ compensation claims, public liability insurance, unemployment insurance, property, casualty or liability insurance, self-insurance obligations or completion, performance, bid performance, appeal or surety bonds;

 (12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the
honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds in the ordinary course; 
 (13) reimbursement obligations with respect to letters of credit issued in the ordinary course of business in support of trade obligations; provided that, upon the drawing of such letters of
credit, such obligations are reimbursed within one year following such drawing or incurrence; 

  
 50 








 (14) accounts payable or other obligations of the Company or any of its
Restricted Subsidiaries to trade creditors created or assumed by the Company or such Restricted Subsidiary in the ordinary course of business in connection with the obtaining of goods and services; and 

(15) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness or the issuance by the
Company of Disqualified Stock or the issuance by any Restricted Subsidiary of preferred stock in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to
renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (15), not to exceed the greater of (i) $150.0 million and (ii) 7% of the Company’s Consolidated Tangible Assets determined as of
the date of such incurrence or issuance. 
 The Company will not incur, and will not permit any Guarantor to incur, any
Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes
and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being
unsecured or by virtue of being secured on a junior priority basis. 
 For purposes of determining compliance with this
Section 5.09, in the event that an item of Indebtedness or Disqualified Stock or preferred stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (15) above, or is entitled to be
incurred pursuant to Section 5.09(a) hereof, the Company will be permitted to divide and classify such item of Indebtedness, Disqualified Stock or preferred stock, as applicable, on the date of its incurrence, or later re-divide and reclassify
all or a portion of such item of Indebtedness, Disqualified Stock or preferred stock, as applicable, in any manner that complies with this Section 5.09. Indebtedness under Credit Facilities outstanding on the Issue Date will initially be deemed
to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest or preferred stock dividends, the accretion or amortization of original issue discount, the
payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or
Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this
Section 5.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued. Further, the reclassification of any lease or other liability of the Company or any of its Restricted Subsidiaries
as Indebtedness due to a change of accounting principles after the Issue Date will not be deemed an incurrence of Indebtedness for purposes of this Section 5.09. 
 For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign
currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness;
provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal


  
 51 








 
amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 5.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
incur pursuant to this Section 5.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. The principal amount of any Permitted Refinancing Indebtedness, if incurred in a different currency
from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

 Section 5.10 Asset Sales. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of consummation of
such Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and 

(2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the
form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash: 
 (A) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated in right of payment to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases the Company or such Restricted Subsidiary from or
indemnifies the Company or such Restricted Subsidiary against further liability; 
 (B) any securities, notes or
other obligations received by the Company or any such Restricted Subsidiary from such transferee that are, within 180 days after receipt thereof, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of
the cash or Cash Equivalents received in that conversion; and 
 (C) any stock or assets of the kind referred to
in clauses (2) or (4) of Section 5.10(b); 
 provided that in the case of any Asset Sale pursuant to a condemnation,
seizure, appropriation or similar taking, including by deed in lieu of condemnation, or any actual or constructive total loss or an agreed or compromised total loss, such Asset Sale shall not be required to satisfy the requirements of clauses
(1) and (2) of this Section 5.10(a). 
 (b) Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds at its option to any combination of the following: 
 (1) to permanently repay any Senior Debt, and if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly permanently reduce commitments with respect thereto; 

  
 52 








 (2) to acquire all or substantially all of the assets of, or any Capital
Stock of, another Person engaged in a Permitted Business, if, in the case of any such acquisition of Capital Stock, such Person is or becomes a Restricted Subsidiary of the Company after giving effect to such acquisition; 

(3) to make a capital expenditure; or 

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a
Permitted Business. 
 The requirement of clause (2), (3) or (4) of this Section 5.10(b) shall be deemed to be
satisfied with respect to any Asset Sale if, within 365 days after such Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) shall have entered into a binding commitment with respect to an acquisition, expenditure or
investment, in compliance with clause (2), (3) or (4) of this Section 5.10(b), and that acquisition, expenditure or investment is substantially completed no later than (i) one year and three months after the date of such Asset
Sale or (ii) with respect to Net Proceeds from any sale, conveyance or other disposition of a Specified Rig, one year and six months after the date of such Asset Sale. 
 (c) Pending the final application of any Net Proceeds, the Company (or the applicable Restricted Subsidiary) may apply such Net Proceeds to temporarily reduce the Indebtedness outstanding under a
revolving Credit Facility or otherwise invest the Net Proceeds in any manner that is not prohibited by the Indenture. 
 (d) Any
Net Proceeds from Asset Sales that are not applied or invested as provided in Section 5.10(b) will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $50.0 million, within five days thereof, the
Company will make an offer, in accordance with Section 4.09 hereof, to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to
offers to purchase, prepay or redeem with the proceeds of sales of assets to purchase, prepay or redeem the maximum principal amount of Notes and such other pari passu Indebtedness (plus all accrued interest on the Indebtedness and the amount
of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus
accrued and unpaid interest, if any, to the date of purchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu
Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will select the Notes and such other pari passu Indebtedness to be purchased on a
pro rata basis (except that any Notes represented in global form will be selected by such method as the Depositary or its nominee or successor may require or, where the nominee or successor is the Trustee, a method that most nearly
approximates pro rata selection as the Trustee deems fair and appropriate), based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes in
denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 

  
 53 








 Section 5.11 Transactions with Affiliates. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any properties or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of the Company (each, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $10.0 million, unless: 
 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary in any material respect than those that would have been obtained in a comparable
transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction,
such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and 
 (2) the Company delivers to the Trustee: 
 (A) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million but no greater than $50.0 million, an Officers’ Certificate certifying that such Affiliate Transaction or series of
related Affiliate Transactions complies with clause (1) of this Section 5.11(a); and 
 (B) with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate
certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with clause (1) of this Section 5.11(a) and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a
majority of the disinterested members of the Board of Directors of the Company. 
 (b) The following items will not be deemed to
be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 5.11(a) hereof: 

(1) any employment agreement, employee benefit plan, officer or director indemnification agreement or any similar
arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto; 
 (2) transactions between or among the Company and/or its Restricted Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an
Equity Interest in, or controls, such Person; 
 (4) payment of customary compensation to, and the provision of
customary indemnity and other benefits on behalf of, officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries; 

  
 54 








 (5) any issuance of Equity Interests (other than Disqualified Stock) of the
Company to, or receipt of capital contributions from, Affiliates of the Company; 
 (6) Permitted Investments and
Restricted Payments that do not violate Section 5.07 hereof; 
 (7) loans or advances to employees in the
ordinary course of business not to exceed (i) $1.0 million to any individual employee and (ii) $2.5 million in the aggregate at any one time outstanding; 

(8) transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise
constitute an Affiliate Transaction except for the fact that one director of such other Person is also a director of the Company or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of
the Company or such Restricted Subsidiary, as applicable, on any matter involving such other Person; 
 (9) any
transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the
Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (1) of Section 5.11(a); and 

(10) transactions pursuant to agreements or arrangements in effect on the Issue Date, or any amendment, modification, or
supplement thereto or replacement thereof, as long as such agreement or arrangement, as so amended, modified, supplemented or replaced is not more disadvantageous to the Company and the Restricted Subsidiaries, in any material respect, than the
agreement or arrangement in existence on the Issue Date. 
 Section 5.12 Liens. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of its property or assets, now owned or hereafter acquired, unless all payments due under the Indenture and the Notes are secured on an
equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien. 

(b) Any Lien on any property or assets of the Company or any of its Restricted Subsidiaries created for the benefit of the Holders
pursuant to Section 5.12(a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged at such time as there are no other Liens of any kind (other than Permitted Liens) on such property or
assets securing Indebtedness. 
 Section 5.13 Business Activities. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses,
except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. 
 Section 5.14
Corporate Existence. 
 Subject to Article 6 hereof, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect its existence. 

  
 55 








 Section 5.15 Offer to Repurchase Upon Change of Control. 

(a) Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of Control Offer”) to each
Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash (the “Change of Control Payment”) equal to 101% of the aggregate
principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the Change of Control Purchase Date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant
interest payment date. Within 30 days following any Change of Control, the Company will mail a notice to each Holder describing briefly the transactions or events that constitute the Change of Control and stating: 

(1) that the Change of Control Offer is being made pursuant to this Section 5.15 and that all Notes properly tendered
and not withdrawn will be accepted for payment; 
 (2) the Change of Control Payment and the purchase date, which
shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Purchase Date”); 
 (3) that any Note not properly tendered will continue to accrue interest; 
 (4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on and after the
Change of Control Purchase Date; 
 (5) that Holders electing to have any Notes purchased pursuant to a Change of
Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the
notice prior to the close of business on the Change of Control Purchase Date; 
 (6) that Holders will be
entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the Change of Control Purchase Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes
delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry
transfer), which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof. 
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those requirements, laws and regulations are
applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 5.15, the Company will comply
with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 5.15 by virtue of such compliance. 
 Promptly following the expiration of the Change of Control Offer on the Change of Control Purchase Date, the Company will, to the extent lawful, accept for payment all Notes or portions of Notes properly
tendered and not withdrawn pursuant to the Change of Control Offer and deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or
portions of Notes being purchased by the Company. 

  
 56 








 Payment of the Change of Control Payment for a Note properly tendered and not withdrawn
prior to the expiration of the Change of Control Offer is conditioned upon delivery of such Note (together with necessary endorsements) to the Paying Agent (whether prior to, on or after the Change of Control Purchase Date), which delivery may be in
book-entry form in accordance with the Applicable Procedures for Notes issued in global form. The Change of Control Payment for such Note will be made promptly following the later of the Business Day following the Change of Control Purchase Date or
the time of delivery of such Note. Except as specifically provided in this Section 5.15, the provisions of Section 4.05 hereof shall be applicable to the payment of the Change of Control Payment. 

(b) The Paying Agent will promptly (but in any case not later than five days after the Change of Control Purchase Date) mail to each
Holder of Notes properly tendered and not withdrawn the Change of Control Payment for such Notes (or if all Notes are then in global form, make such payment through the facilities of the Depositary), 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 new Note will be in a principal amount of $2,000 or
an integral multiple of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer as soon as practicable after the Change of Control Purchase Date. 

(c) Notwithstanding anything to the contrary in this Section 5.15, the Company 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 Section 5.15 and purchases all Notes properly tendered
and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 4.07 hereof, unless and until there is a default in payment of the applicable redemption price. 

(d) In the event that not less than 90% of the aggregate principal amount of the then outstanding Notes are properly tendered and not
withdrawn under a Change of Control Offer and the Company purchases all of such Notes, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the Change of Control
Purchase Date, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on
the Notes that remain outstanding, to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). Sections 4.01, 4.03, 4.04 and 4.05 shall be
applicable to any such redemption. 
 (e) Notwithstanding anything to the contrary contained herein, a Change of Control Offer
may be made in advance of a Change of Control, 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. 

Section 5.16 Limitation on Issuances of Guarantees of Indebtedness. 
 The Company will not permit any of its existing or future Restricted Subsidiaries (other than Immaterial Subsidiaries), or any of its existing Restricted Subsidiaries that ceases to constitute an
Immaterial Subsidiary, to Guarantee the payment of any other Indebtedness (other than Indebtedness and letters of credit under the Credit Agreement) of the Company unless such Restricted Subsidiary executes a supplemental indenture providing for the
Guarantee of the payment of the Notes by such Restricted 

  
 57 








 
Subsidiary, which Note Guarantee will be senior to or pari passu with such Restricted Subsidiary’s Guarantee of such other Indebtedness, and delivers to the Trustee such supplemental
indenture and an Opinion of Counsel satisfactory to the Trustee within 20 Business Days after the date on which such Restricted Subsidiary guaranteed such other Indebtedness. The form of such supplemental indenture is attached as Exhibit B hereto.
To evidence such Note Guarantee, an Officer of such Guarantor will endorse by manual or facsimile signature a notation of such Note Guarantee on each Note thereafter authenticated and delivered by the Trustee. 

Section 5.17 Payments for Consent. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders that consent, waive or agree to amend in the time frame set
forth in the solicitation documents relating to such consent, waiver or amendment. 
 Section 5.18 Designation of Restricted and
Unrestricted Subsidiaries. 
 The Board of Directors of the Company may designate any Restricted Subsidiary of the Company
to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its
Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 5.07 hereof or under one
or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an
Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default. 

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee
a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 5.07 hereof. If,
at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of the Indenture and any Indebtedness of such Subsidiary
will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 5.09 hereof, the Company will be in default of such covenant. The
Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary
of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 5.09 hereof, calculated on a pro forma basis as if such
designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be in existence following such designation. 

  
 58 








 Section 5.19 Payment of Additional Amounts. 

(a) All payments made by the Company under or with respect to the Notes will be made free and clear of and without withholding or
deduction for, or on account of, any present or future tax, duty, assessment, or other governmental charge of whatever nature imposed, levied, collected, withheld or assessed (including any penalties and interest related thereto)
(“Taxes”) unless the withholding or deduction of such Taxes is then required by law. In the event that the Company is succeeded by a Successor Company in a Permitted Foreign Jurisdiction as permitted by Section 6.01 hereof and
if any deduction or withholding for, or on account of, any Taxes imposed or levied by or on behalf of (1) any jurisdiction in which the Company (which, for purposes of this Section 5.19, refers to the Company’s Successor Company) or
any Guarantor is then incorporated, engaged in business, organized or otherwise resident or treated as resident for tax purposes or any political subdivision thereof or therein or (2) any jurisdiction from or through which payment is made by or
on behalf of the Company (including, without limitation, the jurisdiction of any Paying Agent) (each of (1) and (2), a “Tax Jurisdiction”), will at any time be required to be made from any payments made under or with
respect to the Notes, including, without limitation, payments of principal, redemption price, purchase price, interest or premium, the Company will pay such additional amounts (the “Additional Amounts”) as may be necessary in order
that the net amounts received in respect of such payments by each Holder, or beneficial owner of Notes (which for purposes of this Section 5.19 means any person owning Notes directly or indirectly through one or more Holders that, with respect
to a payment on the Notes, acts as a custodian, broker, agent, or otherwise as an intermediary for such person for Tax purposes) in global form, after such withholding, deduction or imposition (including any such withholding, deduction or imposition
from such Additional Amounts) will equal the respective amounts that would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no Additional Amounts will be payable with
respect to: 
 (1) any Taxes to the extent such Taxes would not have been imposed but for such Holder or
beneficial owner being a citizen or resident or national of, or incorporated in, the relevant Tax Jurisdiction in which such Taxes are imposed or having any other present or former connection with the relevant Tax Jurisdiction other than the mere
acquisition, holding, exercise or enforcement of rights, or receipt of payment in respect of the notes; 
 (2)
any Taxes to the extent such Taxes are imposed or withheld as a result of the failure of such Holder or beneficial owner to comply, to the extent such Holder or beneficial owner is legally entitled, with any reasonable written request, made by the
Company or any Guarantor to that Holder or beneficial owner in writing at least 90 days before any such withholding or deduction would be payable, to provide information concerning the nationality, residence or identity of such Holder or beneficial
owner or to make any valid and timely declaration or similar claim or satisfy any certification information or other reporting requirement, which is required or imposed by a statute, treaty, regulation or administrative practice of the relevant Tax
Jurisdiction as a precondition to any exemption from or reduction in all or part of such Taxes; 
 (3) any Taxes
to the extent such Taxes were imposed as a result of the presentation of a Note for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that
the Holder would have been entitled to Additional Amounts had the Note been presented on the last day of such 30 day period); 
 (4) any estate, inheritance, gift, sale, personal property or similar Taxes; 
 (5) any Taxes payable other than by deduction or withholding from payments under, or with respect to, the Notes; or 
 (6) any combination of items (1) through (5) above. 

  
 59 








 The Company will not pay any Additional Amounts to any Holder or beneficial owner who is a
fiduciary or partnership or any other person who is not the sole beneficial owner of the Note to the extent that a beneficiary or settlor with respect to such fiduciary, or a member of such partnership or a beneficial owner thereof, would not have
been entitled to the payment of such Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder. 
 (b) If the Company is succeeded by a Successor Company in a Permitted Foreign Jurisdiction as permitted by Section 6.01 hereof, the Company or a Guarantor, as applicable, will also pay and indemnify
the Holder for any present or future stamp, issue, registration, value added, court or documentary Taxes, or any other excise or property taxes, charges or similar levies (including penalties, interest and any other reasonable expenses related
thereto) or Taxes which are levied by any Tax Jurisdiction on the execution, delivery, registration or enforcement of any of the Notes, the Indenture, any Note Guarantee, or any other document or instrument referred to therein or the receipt of
payments with respect thereto. 
 (c) If the Company or any Guarantor becomes obligated to pay Additional Amounts with respect
to any payment under or with respect to the Notes or any Note Guarantee, the Company or any Guarantor, as applicable, will deliver to the Trustee on a date that is at least 30 days prior to the date of that payment (unless the obligation to pay
Additional Amounts arises after the 30th day prior to that payment date, in which case the Company will notify the Trustee promptly after such obligation arises (and in any event within five Business Days thereof)) an Officers’ Certificate
stating the fact that Additional Amounts will be payable and the amount estimated to be so payable. The Officers’ Certificate must also set forth any other information reasonably necessary to enable the Paying Agents to pay Additional Amounts
to Holders on the relevant payment date. The Trustee shall be entitled to rely solely on such Officers’ Certificate as conclusive proof that such payments are necessary. The Company or any Guarantor, as applicable, will provide the Trustee with
documentation reasonably satisfactory to the Trustee evidencing the payment of Additional Amounts. 
 (d) The Company or any
Guarantor, as applicable, will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the relevant Tax authority in accordance with applicable law. Upon request, the Company or any Guarantor, as
applicable, will provide to the Trustee an official receipt or, if official receipts are not obtainable, other documentation reasonably satisfactory to the Trustee evidencing the payment of any Taxes so deducted or withheld and will attach to each
official receipt or other documentation an Officers’ Certificate stating the amount of such Taxes paid per $1,000 principal amount of the Notes then outstanding. Upon request, copies of those official receipts or other documentation, as the
case may be, will be made available by the Trustee to the Holders. 
 (e) Whenever in the Indenture or the Notes there is
mentioned, in any context, the payment of amounts based upon the principal amount of the Notes or of principal, interest or of any other amount payable under, or with respect to, any of the Notes, such mention shall be deemed to include mention of
the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. 
 (f) The obligations of the Company and the Guarantors under this Section 5.19 will survive termination, defeasance or discharge of the Indenture, any transfer by a Holder or beneficial owner of its
Notes and will apply mutatis mutandis to any jurisdiction in which any successor person to the Company or any Guarantor is incorporated, engaged in business or resident for tax purposes or any jurisdiction from or through which such person makes any
payment on the Notes (or any Note Guarantee) and any department or political subdivision thereof or therein.

 Section 5.20 Changes in Covenants when Notes Rated Investment Grade. 

If on any date following the Issue Date: 
 (1) the Notes are rated either Baa3 or better by Moody’s or BBB- or better by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the

and 
 (2) no Default or Event of Default shall have occurred and be continuing,

 ARTICLE 7

(including the provisions of Sections 5.10 and 5.15 hereof to the extent not described in clause (3) above); 

  
 63 








 (6) default under any mortgage, indenture or instrument under which there
may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries),
whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default: 
 (A) is
caused by a failure to pay principal of, premium, if any, or interest, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or

 (B) results in the acceleration of such Indebtedness prior to its express maturity, 

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under
which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million or more; provided, however, that if any such default is cured or waived or any such acceleration rescinded, or such
Indebtedness is repaid and the Notes have not been accelerated, such Event of Default shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 

(7) failure by the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of
competent jurisdiction aggregating in excess of $50.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed
for a period of 60 days; 
 (8) except as permitted by the Indenture, any Note Guarantee is held in any judicial
proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; 

(9) the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted

(C) orders the liquidation of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any
group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; 
 and the order
or decree remains unstayed and in effect for 60 consecutive days. 
 Section 7.02 Acceleration. 

In the case of an Event of Default specified in clause (9) or (10) of Section 7.01 hereof, all outstanding Notes will
become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the
Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately. 
 The
Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not
conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium, if any, interest, if any, on, the Notes that has become due solely because of the acceleration) have been cured or waived.

 Section 7.03 Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, or interest, if any, on, the Notes or to enforce the
performance of any provision of the Notes or the 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 an Event of Default shall not impair the right or remedy or constitute a waiver of
or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 7.04 Waiver of Past
Defaults. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the
Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium, if any, interest, if
any, or Additional Amounts, if any, on, the Notes (including in connection with an Asset Sale Offer or Change of Control Offer); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may
rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose of the Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

  
 65 








 Section 7.05 Control by Majority. 

Holders of a majority in aggregate principal amount of the then outstanding Notes may 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. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture that the Trustee determines may be
unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability. 
 Section 7.06 Limitation on
Suits. 
 Subject to Section 7.07, no Holder may pursue any remedy with respect to the Indenture or the Notes unless:

 (1) such Holder has previously given the Trustee written notice that an Event of Default is continuing;

 (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request
to the Trustee to pursue the remedy; 
 (3) such Holder or Holders offer and, if requested, provide to the
Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense; 
 (4) the
Trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 

A Holder may not use the 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 use prejudices the rights of another Holder or obtains a preference or priority over another Holder). 

Section 7.07 Rights of Holders to Receive Payment. 
 Notwithstanding any other provision of the Indenture, the right of any Holder to receive payment of principal of, premium, if any, interest, if any, or Additional Amounts, if any, on, the Note, on or
after the respective due dates expressed in the Note (including in connection with an Asset Sale Offer or a Change of Control Offer), 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 7.08 Collection Suit by Trustee. 

If an Event of Default specified in Section 7.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to
recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal, and premium, if any, and interest, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent
lawful, interest 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. 

  
 66 








 Section 7.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to 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 reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other
obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims 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 agents and counsel, and any other amounts due the Trustee under Section 8.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 8.07 hereof out of the estate in any such proceeding shall be denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise.
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, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 7.10
Priorities. 
 If the Trustee collects any money pursuant to this Article 7, it shall pay out the money in the following
order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 8.07 hereof,
including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, interest, if any, and Additional Amounts, if any, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Notes for principal, premium, if any, interest, if any, and Additional Amounts, if any, respectively; and 
 Third: to the Company or the Guarantors or to such party as a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 7.10. 
 Section 7.11 Undertaking for Costs. 
 In any suit for the enforcement
of any right or remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it as a 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, 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 7.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 7.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

 ARTICLE 8 
 TRUSTEE 
 Section 8.01 Duties of Trustee. 

(a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by the
Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b) Except during the continuance of an Event of Default: 

(1) the duties of the Trustee will be determined solely by the express provisions of the Indenture and the Trustee need
perform only those duties that are specifically set forth in the Indenture and no others, and no implied covenants or obligations shall be read into the Indenture against the Trustee; and 

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of the Indenture. However, the Trustee will examine such certificates and opinions to determine whether or not
they conform to the requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 
 (c) The Trustee may not be relieved from liabilities 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 of Section 8.01(b); 

(2) the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is
proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee will not be
liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 7.05 hereof. 
 (d) Whether or not therein expressly so provided, every provision of the Indenture that in any way relates to the Trustee is subject to the provisions of this Section 8.01. 

(e) No provision of the Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture at the request of any Holders, unless such Holder has offered to the Trustee security or indemnity satisfactory to it in its sole discretion against any loss, liability
or expense. 
 (f) The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in
writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. All money received by the Trustee shall, until applied as herein provided, be held in trust for the payment of
the principal of, premium, if any, interest, if any, and Additional Amounts, if any, on the Notes.

Person. The Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains
from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both to be provided. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or
Opinion of Counsel. The Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and will not be
responsible for the misconduct or negligence of any agent appointed with due care.

action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by the Indenture. 
 (e) Unless otherwise specifically provided in the Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company. 

(f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request or
direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

 (g) 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. 

(h) The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either
(1) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee at the Corporate Trust Office of the Trustee by the
Company or by any Holder, and such notice references the Notes and the Indenture. 
 (i) The rights, privileges, protections,
immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person
employed to act hereunder. 
 (j) The Trustee shall not be required to give any bond or surety in respect of the performance of
its powers and duties hereunder. 
 (k) The permissive rights of the Trustee enumerated herein shall not be construed as duties.


  
 69 








 Section 8.03 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 Company or
any Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 8.10 and 8.11 hereof. 

Section 8.04 Trustee’s Disclaimer. 
 The Trustee will not be responsible for and makes no representation as to the validity or adequacy of the Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds
from the Notes or any money paid to the Company or upon the Company’s direction under any provision of the Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it
will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to the Indenture other than its certificate of authentication. 

Section 8.05 Notice of Defaults. 
 If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail to Holders a notice of the Default or Event of Default within 90 days after it occurs.
Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest, if any, on, any Note, 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 8.06 Reports by Trustee to Holders. 
 (a) Within 60 days after
each May 15 beginning with the May 15 following the date of this Supplemental Indenture, and for so long as Notes remain outstanding, the Trustee will mail to the Holders a brief report dated as of such reporting date that complies with
TIA §313(a) (but if no event described in TIA §313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA §313(b). The Trustee will also transmit by
mail all reports as required by TIA §313(c). 
 (b) A copy of each report at the time of its mailing to the Holders will be
mailed by the Trustee to the Company and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA §313(d). The Company will promptly notify the Trustee when the Notes are listed on any stock
exchange or any delisting thereof. 
 Section 8.07 Compensation and Indemnity. 

(a) The Company agrees to pay to the Trustee for its acceptance of the Indenture and services hereunder such compensation as the Company
and the Trustee shall from time to time agree in writing. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all
reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.


  
 70 








 (b) The Company and the Guarantors will indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under the Indenture, including the costs and expenses of enforcing the Indenture against the Company and the Guarantors
(including this Section 8.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties
hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify
the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the
Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. 

(c) The obligations of the Company and the Guarantors under this Section 8.07 will survive the satisfaction and discharge of the
Indenture. 
 (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 8.07, the
Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, or premium, if any, or interest, if any, on, particular Notes. Such Lien will survive the
satisfaction and discharge of the Indenture. 
 (e) When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 7.01(9) or (10) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law. 
 Section 8.08 Replacement of Trustee. 
 (a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this
Section 8.08. 
 (b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so
notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 

(1) the Trustee fails to comply with Section 8.10 hereof; 

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under
any Bankruptcy Law; 
 (3) a custodian or public officer takes charge of the Trustee or its property; or

 (4) the Trustee becomes incapable of acting. 

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly
appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed
by the Company. 

  
 71 








 (d) If a successor Trustee does not take office within 30 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

 (e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with
Section 8.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become
effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under the Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held
by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 8.07 hereof. Notwithstanding replacement of the Trustee pursuant to this
Section 8.08, the Company’s obligations under Section 8.07 hereof will continue for the benefit of the retiring Trustee. 

Section 8.09 Successor Trustee by Merger, etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will
be the successor Trustee; provided, however, that in the case of a transfer of all or substantially all of its corporate trust business to another corporation, the transferee corporation expressly assumes all of the Trustee’s liabilities
hereunder. 
 Section 8.10 Eligibility; Disqualification. 
 There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws
to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of
condition. 
 The Indenture will always have a Trustee who satisfies the requirements of TIA §310(a)(1), (2) and (5).
The Trustee is subject to TIA §310(b). 
 Section 8.11 Preferential Collection of Claims Against Company. 

The Trustee is subject to TIA §311(a), excluding any creditor relationship listed in TIA §311(b). A Trustee who has resigned or
been removed shall be subject to TIA §311(a) to the extent indicated therein. 
 ARTICLE 9 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 9.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Company may at any time, pursuant to a resolution of its Board of Directors set forth in an Officers’ Certificate, elect to have
either Section 9.02 or 9.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 9. 

  
 72 








 Section 9.02 Legal Defeasance and Discharge. 

Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.02, the Company and each
of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date
the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 9.05 hereof and the other Sections of the Indenture referred to in clauses
(1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and the Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging
the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 
 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and premium, if any, interest, if any, or Additional Amounts, if any, on, such Notes when such payments
are due from the trust referred to in Section 9.04 hereof; 
 (2) the Company’s obligations with
respect to such Notes under Sections 3.04, 3.06, 3.07, 3.10 and 5.02 hereof; 
 (3) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith; and 
 (4) this Article 9. 
 Subject to compliance with this Article 9, the Company may
exercise its option under this Section 9.02 notwithstanding the prior exercise of its option under Section 9.03 hereof. 
 Section 9.03 Covenant Defeasance. 
 Upon the Company’s exercise
under Section 9.01 hereof of the option applicable to this Section 9.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from each of their
obligations under the covenants contained in Sections 4.09, 5.03, 5.05, 5.07, 5.08, 5.09, 5.10, 5.11, 5.12, 5.13, 5.15, 5.16, 5.17, 5.18 and 5.19 hereof and clauses (3) and (4) of Section 6.01 hereof and any covenant added to the
Indenture subsequent to the Issue Date pursuant to Section 10.01 hereof with respect to all outstanding Notes on and after the date the conditions set forth in Section 9.04 hereof are satisfied (hereinafter, “Covenant
Defeasance”), and the Notes will 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 will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to
the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no 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 will not constitute a Default or an Event of Default under
Section 7.01 hereof, but, except as specified above, the remainder of the Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 9.01 hereof of the option
applicable to this Section 9.03, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, Sections 7.01(3), (4), (5), (6), (7) and (8) hereof will not constitute Events of Default. 

  
 73 








 Section 9.04 Conditions to Legal or Covenant Defeasance. 

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 9.02 or 9.03 hereof: 

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion (except in the case of cash) of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to
pay the principal of, and premium, if any, and interest, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being
defeased to such stated date for payment or to a particular redemption date; 
 (2) in the case of an election
under Section 9.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that: 
 (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or 
 (B) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of
the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to 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 an election under
Section 9.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes
as a result of such Covenant Defeasance and will be subject to 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 or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default
or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings); 

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default
under, any material agreement or instrument (other than the Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of the Guarantors is a party or by which the Company or any
of the Guarantors is bound; 

  
 74 








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

 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 9.05
Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to
Section 9.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 9.05 and Section 12.02, the
“Trustee”) pursuant to Section 9.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such
money need not be segregated from other funds except to the extent required by law. 
 The Company will pay and indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 9.04 hereof 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. 
 Notwithstanding anything in
this Article 9 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 9.04 hereof which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 9.04(1) hereof), are in excess of the amount thereof that
would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 If the Company
exercises either its Legal Defeasance or Covenant Defeasance option, each Guarantor shall be released and relieved of any obligations under its Note Guarantee and any security for the Notes (other than the trust fund described in Section 9.04
hereof) shall be released. 
 Section 9.06 Repayment to Company. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or
premium, if any, or interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall be paid to the Company on its request or (if then held by the
Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in
the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or
publication, any unclaimed balance of such money then remaining will be repaid to the Company. 

  
 75 








 Section 9.07 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with
Section 9.02 or 9.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’
obligations under the Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 9.02 or 9.03 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such money or non-callable Government Securities in accordance with Section 9.02 or 9.03 hereof, as the case may be; provided, however, that, if the Company or any Guarantor makes any payment of principal of, or premium, if any, or
interest, if any, on, any Note following the reinstatement of its obligations, the Company or such Guarantor, as applicable, will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or non-callable
Government Securities held by the Trustee or Paying Agent. 
 ARTICLE 10 

AMENDMENT, SUPPLEMENT AND WAIVER 

Section 10.01 Without Consent of Holders. 
 Notwithstanding Section 10.02 of this Supplemental Indenture, without the consent of any Holder, the Company, the Guarantors, if any, and the Trustee may amend or supplement the Indenture, the Notes
or the Note Guarantees: 
 (1) to cure any ambiguity, defect or inconsistency; 

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes; 

(3) to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of the Notes and
Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of the Company’s or such Guarantor’s assets, as applicable, in accordance with Article 6; 

(4) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely
affect the legal rights hereunder of any Holder, including without limitation, to secure the Notes or the Note Guarantees pursuant to Section 5.12 hereof; 
 (5) to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA; 

(6) to conform the text of the Indenture, the Notes or the Note Guarantees to any provision of the “Description of
Notes” section of the Company’s Prospectus dated January 12, 2012, as filed with the SEC on January 13, 2012, relating to the initial offering of the Notes, to the extent that such provision in that “Description of
Notes” was intended to be a substantially verbatim recitation of a provision of the Indenture, the Notes or the Note Guarantees, which intent may be evidenced by an Officers’ Certificate to that effect; 

  
 76 








 (7) to provide for the issuance of Additional Notes in accordance with the
limitations set forth in the Indenture as of the Issue Date; 
 (8) to allow any Guarantor to execute a
supplemental indenture and/or a Note Guarantee with respect to the Notes; 
 (9) to add any additional Guarantor
or to evidence the release of any Guarantor from its Note Guarantee, in each case as provided in the Indenture; or 
 (10) to evidence or provide for the acceptance of appointment under the Indenture of a successor Trustee. 
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the
documents described in Section 10.06 hereof, the Trustee will, subject to Section 10.06, join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of the
Indenture and to make any further appropriate agreements and stipulations that may be therein contained. 
 Section 10.02 With Consent
of Holders. 
 Except as provided below in this Section 10.02, the Company, the Guarantors and the Trustee may amend or
supplement the Indenture (including, without limitation, Section 4.09, 5.10 and 5.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding
Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections
7.04 and 7.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, or premium, if any, or interest, if any, on, the Notes, except a payment default resulting from an
acceleration that has been rescinded) or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes
(including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Sections 3.08 and
3.09 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 10.02. 

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or
supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 10.06 hereof, the Trustee
will, subject to Section 10.06, join with the Company and the Guarantors in the execution of such amended or supplemental indenture. 
 It is not necessary for the consent of the Holders under this Section 10.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent
approves the substance thereof. 
 After an amendment, supplement or waiver under this Section 10.02 becomes effective, the
Company will mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of
any such amended or supplemental indenture or waiver. 

  
 77 








 The right of any Holder to participate in any consent required or sought pursuant to any
provision of the Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of the Notes as of a date
identified by the Company in a notice furnished to Holders in accordance with the terms of the Indenture. 
 Subject to Sections
7.04 and 7.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of the Indenture, the Notes or the
Note Guarantees (including, without limitation, waivers obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). However, without the consent of each Holder affected, an amendment, supplement or waiver may not
(with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the percentage of principal amount of
Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce any premium payable upon
the redemption of any Notes or change the date on which any Notes are subject to redemption (other than the notice provisions) or waive any payment with respect to the redemption of the Notes; provided, however, that, solely for the avoidance
of doubt, and without any other implication, any purchase or repurchase of the Notes (including pursuant to the provisions of Sections 4.09, 5.10 and 5.15 hereof) shall not be deemed a redemption of the Notes; 

(3) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 

(4) waive a Default or Event of Default in the payment of principal of, or premium, if any, interest, if any, or
Additional Amounts, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such
acceleration); 
 (5) make any Note payable in money other than that stated in the Notes; 

(6) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders to
receive payments of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes (other than waivers permitted by clause (7) below); 

(7) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 4.09,
5.10 or 5.15 hereof);

 78 








 Section 10.03 Compliance with Trust Indenture Act. 

Every amendment or supplement to the Indenture, the Notes or the Note Guarantees will be set forth in a amended or supplemental indenture
that complies with the TIA as then in effect. 
 Section 10.04 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
its Note or portion of a Note if the Trustee receives written notice of revocation before a date and time therefor identified by the Company in a notice furnished to such Holder in accordance with the terms of the Indenture or, if no such date and
time shall be identified, the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

The Company may, but shall not be obligated to, fix a record date (which need not comply with TIA § 316(c)) for the purpose of
determining the Holders entitled to consent to any amendment, supplement or waiver or to take any other action under the Indenture. If a record date is fixed, then notwithstanding the provisions 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 consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to
be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the principal amount of Notes required hereunder for such amendment, supplement or waiver to be
effective shall have also been given and not revoked within such 90-day period. 
 After an amendment, supplement or waiver
becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (1) through (9) of Section 10.02 hereof. In such case, the amendment, supplement or waiver shall bind each Holder who has consented to
it and every subsequent Holder that evidences the same debt as the consenting Holder’s Note. 
 Section 10.05 Notation on or
Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note
thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or
waiver. 
 Section 10.06 Trustee to Sign Amendments, etc. 
 The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 10 if the amendment or supplement does not adversely affect the rights, duties, liabilities or
immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In executing or refusing to execute any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 8.01 hereof) will be fully
protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by
the Indenture. 

  
 79 








 Section 10.07 Effect of Supplemental Indentures. 

Upon the execution of any supplemental indenture under this Article 10, the Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of the Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 

ARTICLE 11 
 NOTE
GUARANTEES 
 Section 11.01 Guarantee. 
 (a) Subject to the provisions of this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally 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 the Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: 

(1) the principal of, and premium, if any, and interest, if any, on, the Notes will be promptly paid in full when due,
whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and premium, if any, and interest, if any, on, the Notes, if lawful, and all other payment obligations of the Company to the Holders or the
Trustee hereunder or thereunder will be promptly paid in full, all in accordance with the terms of the Indenture and the Notes; and 
 (2) in case of any extension of time of payment or renewal of any Notes, that same will be promptly paid in full when due in accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise. 
 Failing payment when due of any amount so guaranteed for whatever reason, the
Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or the 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 of the Indenture or the Notes, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance (other than
payment) which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever, and covenants that this Note Guarantee will not be discharged (other than in accordance with Section 9.02, 11.06 or 12.01) except
by complete performance of the obligations contained in the Notes and the Indenture. 
 (c) If any Holder or the Trustee is
required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by any of them to the Trustee or
such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 

  
 80 








 (d) Each Guarantor agrees that, as between the Guarantors, on the one hand, and the Holders
and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 7 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 7 hereof, such obligations (whether or not due and payable) will
forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the
Holders under the Note Guarantee. 
 Section 11.02 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 Note
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 or state law to the extent applicable to
any Note 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 11 will be limited to the maximum amount that will, after
giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor 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 11, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. Each Guarantor that
makes a payment under its Note Guarantee shall be entitled, upon payment in full of all guaranteed Obligations under the Indenture, to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion
of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP. 

Section 11.03 Execution and Delivery of Note Guarantee. 
 To evidence its Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit C hereto will be
endorsed by an Officer of such Guarantor on each Note thereafter authenticated and delivered by the Trustee. 
 Each Guarantor
hereby agrees that its Note Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 

If an Officer whose signature is on any notation of Note Guarantee no longer holds that office at the time the Trustee authenticates the
Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless. 
 The delivery of any Note by the
Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in Section 11.01 on behalf of the Guarantors, if any, and the execution of a supplemental indenture pursuant to Section 5.16
and a notation of Note Guarantee will constitute due delivery of a future Note Guarantee on behalf of the applicable Guarantors. 

  
 81 








 Section 11.04 Subrogation. 

Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by any Guarantor pursuant
to the provisions of Section 11.01; provided that, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under the
Indenture or the Notes shall have been paid in full. 
 Section 11.05 Guarantors May Consolidate, etc., on Certain Terms.

 Except as otherwise provided in Section 11.06 hereof, no Guarantor may sell or otherwise dispose of, in one or more
related transactions, all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless: 

(1) immediately after giving effect to such transaction, or series of related transactions, no Default or Event of Default
exists; and 
 (2) either: 

(A) subject to Section 11.06 hereof, the Person acquiring the assets in any such sale or disposition or the Person
formed by or surviving any such consolidation or merger (if other than the Guarantor) unconditionally assumes all the obligations of that Guarantor under its Note Guarantee and the Indenture on the terms set forth therein or herein, pursuant to a
supplemental indenture satisfactory to the Trustee; or 
 (B) the Net Proceeds of such sale or other disposition
are applied in accordance with the applicable provisions of the Indenture, including without limitation, Sections 4.09 and 5.10 hereof. 
 In case of any such consolidation, merger, sale or disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory to the
Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the
Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall
not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under the Indenture as the Note Guarantees theretofore and thereafter issued in accordance
with the terms of the Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. 

Except as set forth in Articles 5 and 6 hereof, and notwithstanding clauses 2(A) and (B) above, nothing contained in the Indenture
or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or disposition of all or substantially all the assets of a Guarantor to the Company or another
Guarantor. 

  
 82 








 Section 11.06 Releases. 

The Note Guarantee of any Guarantor shall be automatically and unconditionally released and discharged, and no further action by such
Guarantor, the Company or the Trustee is required for the release of such Guarantor’s Note Guarantee: 
 (1)
in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company
or a Restricted Subsidiary of the Company, if such sale or other disposition does not violate Sections 4.09 or 5.10 hereof; 
 (2) in connection with any sale or other disposition of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted
Subsidiary of the Company, if such sale or disposition does not violate Sections 4.09 or 5.10 hereof and such Guarantor ceases to be a Subsidiary of the Company as a result of the sale or other disposition; 

(3) if the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance
with Section 5.18 hereof; 
 (4) upon Legal Defeasance or Covenant Defeasance in accordance with Article 9
hereof or satisfaction and discharge of the Indenture in accordance with Article 12 hereof; 
 (5) upon the
liquidation or dissolution of such Guarantor provided that no Default or Event of Default has occurred or is continuing; 
 (6) upon the release or discharge of such Guarantor from the guarantee of Indebtedness that resulted in the obligation of such Guarantor to guarantee the Notes (except as a result of payment under any
such guarantee); or 
 (7) upon such Guarantor consolidating with, merging into or transferring all of its assets
to the Company or another Guarantor, and as a result of, or in connection with, such transaction such Guarantor dissolving or otherwise ceasing to exist. 
 Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that any of the conditions described in clauses (1) through (7) of this
Section 11.06 has occurred, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee and the Indenture. 

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 11.06 will remain liable for
the full amount of principal of, and premium, if any, and interest, if any, on, the Notes and for the other obligations of any Guarantor under the Indenture as provided in this Article 11. 

  
 83 








 ARTICLE 12 
 SATISFACTION AND DISCHARGE 
 Section 12.01 Satisfaction and Discharge. 

The Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder (except with respect to the
obligations in Sections 3.03, 3.04, 3.05, 3.06 and 3.07, which shall survive until the Notes have been canceled, and the rights, protections and immunities of the Trustee), when: 

(1) either: 
 (A) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to
the Company, have been delivered to the Trustee for cancellation; or 
 (B) all Notes that have not been
delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused
to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any
reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal of, premium, if any, on, and interest, if any, on, the Notes to the date of maturity or redemption;

 (2) in respect of subclause (B) of clause (1) of this Section 12.01, no Default or Event of
Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating
to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a
party or by which the Company or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating
to other Indebtedness, and in each case the granting of Liens to secure such borrowings); 
 (3) the Company or
any Guarantor has paid or caused to be paid all sums payable by it under the Indenture; and 
 (4) the Company
has delivered irrevocable instructions to the Trustee under the Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 

In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to
satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of the Indenture, if money has
been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 12.01, the provisions of Sections 12.02 and 9.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge
those provisions of Section 8.07 hereof, that, by their terms, survive the satisfaction and discharge of the Indenture. 

  
 84 








 Section 12.02 Application of Trust Money; Reinstatement. 

Subject to the provisions of Section 9.06 hereof, all money and non-callable Government Securities (including the proceeds thereof)
deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and the Indenture, to the payment, either directly or through any Paying Agent (including the
Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, and interest, if any, for whose payment such money has been deposited with the Trustee; but such money need not
be segregated from other funds except to the extent required by law. 
 The Company will pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 12.01 hereof 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. 
 Notwithstanding anything in this
Article 12 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 12.01 hereof which are in excess of
the amount thereof that would then be required to be deposited to effect the satisfaction and discharge of the Indenture pursuant to Section 12.01. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 12.01 hereof by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under the Indenture and the Notes and the Note Guarantees shall be revived and reinstated as though no deposit had occurred
pursuant to Section 12.01 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 12.01; provided that if the Company has made any payment of
principal of, or premium, if any, or interest, if any, on, any Notes following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government
Securities held by the Trustee or Paying Agent.

 [Reverse of Note] 
 6.50% Senior Notes due 2020 
 Capitalized terms used herein have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1)
INTEREST. Atwood Oceanics, Inc., a Texas corporation (the “Company”), promises to pay or cause to be paid interest on the principal amount of this Note at 6.50% per annum from
January 18, 2012. The Company will pay interest semi-annually in arrears on February 1 and August 1 of each year (each, an “Interest Payment Date”). 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 January 18, 2012; provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest
shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be August 1, 2012. The Company will pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders
at the close of business on the January 15 or July 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 3.12 of
the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, interest, if any, and Additional Amounts, if any, at the office or agency of the Paying Agent and Registrar within the City and State of
New York, or, at the option of the Company, payment of interest may be made by wire transfer of immediately available funds for Global Notes or by check mailed to the Holders at their addresses set forth in the register of Holders. Such payment will
be 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. If a payment date is not a Business Day at a place of payment, payment may be made at that place on the
next succeeding Business Day, and no interest shall accrue for the intervening period. 
 (3)
PAYING AGENT AND REGISTRAR. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may
change the Paying Agent or Registrar without prior notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 
 (4) INDENTURE. The Company issued the Notes under the First Supplemental Indenture, dated as of January 18, 2012 (the “Supplemental Indenture”),
between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to an Indenture, dated as of January 18, 2012 (the “Base
Indenture”, as amended and supplemented by the Supplemental Indenture, 

  
 A-3








 
and as further amended and supplemented from time to time, in each case, with respect to the Notes, the “Indenture’), between the Company 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 TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and such 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 Notes are unsecured obligations of the Company. 

(5) OPTIONAL REDEMPTION. 

(A) At any time prior to February 1, 2015, the Company may on any one or more occasions redeem up to 35% of the
aggregate principal amount of Notes issued under the Indenture at a redemption price equal to 106.50% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of
Holders on the relevant record date to receive interest on the relevant Interest Payment Date), with the net cash proceeds of one or more Equity Offerings by the Company; provided that: 

(1) at least 65% of the aggregate principal amount of the Initial Notes (excluding Notes held by the Company and its
Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 
 (2) the redemption
occurs within 90 days of the date of the closing of such Equity Offering. 
 (B) At any time prior to
February 1, 2016, the Company may on any one or more occasions redeem all or a part of the Notes at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid
interest, if any, to the applicable date of redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date. The Company will (i) determine the Treasury Rate at least one
Business Day prior to the redemption date and (ii) prior to such redemption date file with the Trustee an Officers’ Certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable
detail. 
 (C) On or after February 1, 2016, the Company may on any one or more occasions redeem all or a
part of the Notes at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the Notes redeemed, to the applicable redemption date, if redeemed during the twelve-month period
beginning on February 1 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant Interest Payment Date: 

 

					
	 Year
	  	Percentage	 
	 2016
	  	 	103.250	% 
	 2017
	  	 	101.625	% 
	 2018 and thereafter
	  	 	100.000	% 

 (D) The Company may redeem the Notes, in whole but not in part, at its discretion at any
time upon giving not less than 30 nor more than 60 days’ prior notice to the Holders (which notice will be irrevocable and given in accordance with Section 4.03 of the Indenture), at a redemption price equal to 100% of the principal amount
thereof, together with accrued and unpaid interest, if any, to the date fixed by the Company for redemption (a “Tax 

  
 A-4








 
Redemption Date”) and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise (subject to the rights
of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date and Additional Amounts, if any, in respect thereof), if on the next date on which any amount would be payable in respect of the Notes, the Company
is or would be required to pay Additional Amounts, and the Company cannot avoid any such payment obligation by taking reasonable measures available (including, for the avoidance of doubt, the appointment of a new Paying Agent), and the requirement
arises as a result of: 
 (1) any change in, or amendment to, the laws (or any regulations or rulings
promulgated thereunder) of the relevant Tax Jurisdiction affecting taxation, which change or amendment has not been publicly announced before and which becomes effective on or after the date on which the Tax Jurisdiction imposing the relevant
withholding or deduction became the applicable Tax Jurisdiction under the Indenture; or 
 (2) any change in, or
amendment to, the existing official position regarding the application, administration or interpretation of such laws, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction or a change in published
practice), which change, amendment, application or interpretation has not been publicly announced before and becomes effective on or after the date on which the Tax Jurisdiction imposing the relevant withholding or deduction became the applicable
Tax Jurisdiction under the Indenture). 
 (E) In the event that not less than 90% of the aggregate principal
amount of the then outstanding Notes are properly tendered and not withdrawn under a Change of Control Offer and the Company purchases all of such Notes, the Company will have the right, upon not less than 30 nor more than 60 days’ prior
notice, given not more than 30 days following the Change of Control Purchase Date, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not
included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant
Interest Payment Date). 
 (F) Unless the Company defaults in the payment of the redemption price, interest will
cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date. 
 (6)
MANDATORY REDEMPTION. The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 

(7) REPURCHASE AT THE OPTION OF
HOLDER. Subject to the additional terms and conditions set forth in the Indenture: 
 (A) If
there is a Change of Control, the Company will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that
Holder’s Notes at a purchase price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the Change
of Control Purchase Date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Company will mail a notice to each Holder
setting forth the procedures governing the Change of Control Offer as required by the Indenture. 

  
 A-5








 (B) If the Company or a Restricted Subsidiary of the Company consummates any
Asset Sales, within five days of each date on which the aggregate amount of Excess Proceeds exceeds $50.0 million, the Company will make an Asset Sale Offer, in accordance with the Indenture, to all Holders and all holders of other Indebtedness that
is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets to purchase, prepay or redeem the maximum principal
amount of Notes and such other pari passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed
out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase, prepayment or redemption, subject to the rights of Holders on the
relevant record date to receive interest due on the relevant Interest Payment Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not
otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Company will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis (except that any Notes represented in global form will be selected by such method as the Depositary or its nominee
or successor may require or, where the nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate), based on the amounts tendered or required to be prepaid or redeemed
(with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess
Proceeds will be reset at zero. Holders that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled
“Option of Holder to Elect Purchase” attached to the Notes. 
 (8) NOTICE
OF REDEMPTION. At least 30 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes
are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the
Indenture pursuant to Articles 9 or 12 thereof. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire
outstanding amount of Notes held by such Holder shall be redeemed or purchased. No Notes of $2,000 or less in principal amount can be redeemed in part. 
 (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. 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 Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed
portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. 

  
 A-6








 (10) PERSONS DEEMED
OWNERS. The registered Holder of a Note may be treated as the owner of it for all purposes. Only registered Holders have rights under the Indenture. 

(11) AMENDMENT, SUPPLEMENT AND WAIVER.
Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including Additional
Notes, if any) voting as a single class, and any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, or premium, if any, or interest, if any, on, the Notes, except a payment default
resulting from an acceleration that has been rescinded) or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then
outstanding Notes (including Additional Notes, if any) voting as a single class. Without the consent of any Holder, the Indenture, the Notes or the Note Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes and Note Guarantees in the case of a merger or
consolidation or sale of all or substantially all of the Company’s or such Guarantor’s assets, as applicable, in accordance with the Indenture, to make any change that would provide any additional rights or benefits to the Holders or that
does not adversely affect the legal rights under the Indenture of any Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, to conform the text of the Indenture, the Notes
or the Note Guarantees to any provision of the “Description of Notes” section of the Company’s Prospectus dated January 12, 2012, as filed with the SEC on January 13, 2012, relating to the initial offering of the Notes, to
the extent that such provision in that “Description of Notes” was intended to be a substantially verbatim recitation of a provision of the Indenture, the Notes or the Note Guarantees, which intent may be evidenced by an Officers’
Certificate to that effect, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture as of the Issue Date, to allow any Guarantor to execute a supplemental indenture to the Indenture and/or a Note
Guarantee with respect to the Notes, to add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee, in each case as provided in the Indenture, or to evidence or provide for the acceptance of appointment under
the Indenture of a successor Trustee. 
 (12) DEFAULTS AND
REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest, if any, on, the Notes; (ii) default in the payment when due (at maturity, upon redemption or otherwise) of
the principal of, or premium, if any, on the Notes, (iii) failure by the Company or any of its Restricted Subsidiaries to comply with the provisions of Section 6.01 of the Indenture or to consummate a purchase of Notes when required
pursuant to Sections 5.10 or 5.15 of the Indenture; (iv) failure by the Company for 120 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a

aggregate principal amount of the Notes then outstanding voting as a single class to comply with any other agreements in the Indenture (including the provisions of Sections 5.10 and 5.15 of the Indenture) to the extent not described in clause
(iii) above); (vi) default under certain other agreements relating to certain Indebtedness of the Company or any of its Restricted 

  
 A-7








 
Subsidiaries which default is a Payment Default or results in the acceleration of such Indebtedness prior to its express maturity; (vii) failure by the Company or any of its Restricted
Subsidiaries to pay certain final judgments, which judgments are not paid, discharged or stayed for a period of 60 days; (viii) except as permitted by the Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or
invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; and (ix) certain events of bankruptcy or
insolvency with respect to the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary. In the case of an Event of Default
arising from certain events of bankruptcy or insolvency described in clause (ix), all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may 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. The Trustee may withhold from Holders notice of any Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, interest, if any, or Additional Amounts, if any, on
the Notes) 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 notice is in the interests of the Holders. The Holders of
a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all the Holders, waive an existing Default or Event of Default and its consequences under the Indenture, except a continuing
Default or Event of Default in the payment of principal of, or premium, if any, or interest, if any, on, the Notes (including in connection with an Asset Sale Offer or Change of Control Offer). The Holders of a majority in aggregate principal amount
of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all the Notes, rescind an acceleration and its consequences under the Indenture, if the rescission would not conflict with any judgment or decree and if
all existing Events of Default (except nonpayment of principal of, premium, if any, interest, if any, on, the Notes that has become due solely because of the acceleration) have been cured or waived. The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 

(13) TRUSTEE DEALINGS WITH COMPANY. The
Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 

(14) NO RECOURSE AGAINST OTHERS. No
director, officer, employee, incorporator or shareholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture or the Note Guarantees or for any claim
based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not
be effective to waive liabilities under the federal securities laws.

 SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of
