(including, for the avoidance of doubt, Indebtedness incurred in the ordinary course of such Person’s business to acquire assets used or useful in its business), other than the Issuer or a Restricted Subsidiary, existing at the time such Person

voting power of the total outstanding Voting Stock of the Issuer; 
 (3) during any period of two consecutive
years, individuals who at the beginning of such period constituted the Board of Directors (together with any new directors whose election to such Board of Directors or whose nomination for election by the stockholders of the Issuer was recommended

arrangement) occurring during the Four-Quarter Period or at any time subsequent to the last day of the Four-Quarter Period and on or prior to the Transaction Date, as if such incurrence, repayment, repurchase, issuance, retirement, extinguishment or

In calculating Consolidated Interest Expense for purposes of determining the denominator (but not the numerator) of this Consolidated
Interest Coverage Ratio: 
 (1) interest on outstanding Indebtedness determined on a fluctuating basis as of the
Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued during the Four-Quarter Period at a fixed rate per annum equal to the rate of interest on such Indebtedness in effect on the Transaction Date;

 (2) if interest on any Indebtedness actually incurred on the Transaction Date may optionally be determined at
an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four-Quarter Period;
and 
 (3) notwithstanding clause (1) or (2) above, interest on Indebtedness determined on a
fluctuating basis, to the extent such interest is covered by agreements relating to Hedging Obligations, shall be deemed to have accrued during the Four-Quarter Period at the rate per annum resulting after giving effect to the operation of these
agreements.

 ARTICLE 2 
 THE NOTES 
 Section 2.01. Form and Dating. 

The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes
may have notations, legends or endorsements required by law or Depository rule or usage. The form of the Notes and any notation, legend or endorsement on them shall be satisfactory to both the Issuer and the Trustee. Each Note shall be dated the
date of its issuance and shall show the date of its authentication. 
 The terms and provisions contained in the Notes, annexed
hereto as Exhibit A, shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Issuer and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby. 
 The Notes shall be issued initially in the form of one or more permanent global Notes
(the “Global Notes”). Notes offered and sold (i) in reliance on Rule 144A shall be issued initially in the form of one or more permanent Global Notes in registered form, substantially in the form set forth in Exhibit A
(the “ Rule 144A Global Note”) and (ii) in offshore transactions in reliance on Regulation S shall be issued initially in the form of one or more permanent global Notes in registered form, substantially in the form set forth in
Exhibit A (the “Regulation S Global Note”), and in each case shall be deposited with the Trustee, as custodian for the Depository, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. Notes
transferred to Institutional Accredited Investors may be represented by a permanent Global Note in registered form, substantially in the form set forth in Exhibit A, and if so represented shall be deposited with the Trustee, as custodian for
the Depository, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of any Global Note may from time to time be increased or decreased by adjustments made on the records of the
Trustee, as custodian for the Depository, as hereinafter provided. 
 Section 2.02. Execution and Authentication. 

The Notes shall be executed on behalf of the Issuer by two Officers of the Issuer. Such signatures may be either manual or facsimile.

 If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the
Note shall be valid nevertheless. 
 A Note shall not be valid until an authorized signatory of the Trustee signs the
certificate of authentication on the Note. Such signature shall be manual. Such signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 

The Trustee or an authentication agent (the “Authenticating Agent”) shall authenticate (i) Initial Notes for
original issue on the date of this Indenture in the aggregate principal amount not to exceed $200,000,000 and (ii) additional Notes (“Additional Notes”) for original issue following the date of this Indenture (so long as
permitted by the terms of this Indenture, including, without limitation, Section 4.10 hereof). The written order shall specify the amount of Notes to be authenticated, the date on which the Notes are to be authenticated and shall further
specify the amount of such Notes to be issued as a Global Note or Certificated Notes. 
 Notwithstanding the foregoing, all
Notes issued under this Indenture shall vote and consent together on all matters (as to which any of such Notes may vote or consent) as one class and no series of Notes will have the right to vote or consent as a separate class on any matter.

 The Trustee may appoint an Authenticating Agent to authenticate Notes. Any such appointment shall be evidenced by an
instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. An Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes
authentication by such Authenticating Agent. An Authenticating Agent has the same right as an Agent to deal with the Issuer and Affiliates of the Issuer. 

  
 -25-








 The Notes shall be issuable only in registered form without coupons and only in
denominations of $2,000 and integral multiples of $1,000 in excess thereof. 
 Section 2.03. Registrar and Paying Agent. 

The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange
(“Registrar”), where Notes may be presented for payment (“Paying Agent”) and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Registrar shall keep a
register of the Notes and of their transfer and exchange. The Registrar shall provide the Issuer a current copy of such register from time to time upon request of the Issuer. The Issuer may have one or more co-Registrars and one or more additional
Paying Agents. Neither the Issuer nor any Affiliate of the Issuer may act as Paying Agent. The Issuer may change any Paying Agent, Registrar or co-Registrar without notice to any Holder. 

The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement
the provisions of this Indenture that relate to such Agent. 
 The Issuer shall notify the Trustee of the name and address of
any such Agent. If the Issuer fails to maintain a Registrar or Paying Agent, or agent for service of notices and demands, or fails to give the foregoing notice, the Trustee shall act as such. The Issuer initially appoints the Trustee as Registrar,
Paying Agent and agent for service of notices and demands in connection with the Notes. 
 Section 2.04. Paying Agent to Hold Assets in
Trust. 
 The Issuer shall require each Paying Agent other than the Trustee to agree in writing that each Paying Agent shall
hold in trust for the benefit of the Holders or the Trustee all assets held by the Paying Agent for the payment of principal of or interest on Notes (whether such assets have been distributed to it by the Issuer or any other obligor on the Notes),
and shall notify the Trustee in writing of any Default in making any such payment. The Issuer at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any
time during the continuance of any Default in any payment due on the Notes, upon written request to a Paying Agent, require such Paying Agent to forthwith distribute to the Trustee all assets so held in trust by such Paying Agent together with a
complete accounting of such sums. Upon distribution to the Trustee of all assets that shall have been delivered by the Issuer to the Paying Agent, the Paying Agent shall have no further liability for such assets. 

Section 2.05. Noteholder Lists. 
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer
shall furnish or cause the Registrar to furnish to the Trustee on or before each March 15 and September 15 in each year, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee
may reasonably require of the names and addresses of Holders which list may be conclusively relied on by the Trustee. 
 Section 2.06.
Transfer and Exchange. 
 Subject to the provisions of Sections 2.15 and 2.16 hereof, when Notes are presented to the
Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations of the same series, the Registrar or co-Registrar shall register the
transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a
written instrument of transfer in form satisfactory to the Issuer and the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. To permit registrations of transfer and exchanges, the Issuer shall
execute and the Trustee shall authenticate Notes at the Registrar’s or co-Registrar’s request. 

  
 -26-








 
No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge in
connection therewith payable by the transferor of such Notes (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Section 2.10, 3.06, 4.12, 4.15 or 8.05 hereof, in which event the
Issuer shall be responsible for the payment of such taxes). 
 Without the prior consent of the Issuer, the Registrar or
co-Registrar shall not be required to register the transfer of or exchange of any Note (i) during a period of 15 days before a selection of Notes to be redeemed, (ii) selected for redemption in whole or in part pursuant to Article 3
hereof, except the unredeemed portion of any Note being redeemed in part, or (iii) between a Record Date and the next succeeding Interest Payment Date. 
 Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Notes may be effected only through a book-entry system maintained by the
Depository, and that ownership of a beneficial interest in the Note shall be required to be reflected in a book entry. 
 Section 2.07.
Replacement Notes. 
 If a mutilated Note is surrendered to the Trustee or if the Holder presents evidence to the
satisfaction of the Issuer and the Trustee that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note. An indemnity or a security bond may be required by the Issuer or the
Trustee that is sufficient in the judgment of the Issuer and the Trustee to protect the Issuer, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. In every case of destruction, loss or theft, the applicant
shall also furnish to the Issuer and to the Trustee evidence to their satisfaction of the destruction, loss or the theft of such Note and the ownership thereof. Each of the Issuer and the Trustee may charge for its expenses in replacing a Note. In
the event any such mutilated, lost, destroyed or wrongfully taken Note has become due and payable, the Issuer in its discretion may pay such Note instead of issuing a new Note in replacement thereof. The provisions of this Section 2.07 are
exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes. 

Every replacement Note is an additional obligation of the Issuer. 
 Section 2.08. Outstanding Notes. 
 Notes outstanding at any time are
all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, and those described in this Section 2.08 as not outstanding. 

If a Note is replaced pursuant to Section 2.07 hereof (other than a mutilated Note surrendered for replacement), it ceases to be
outstanding until the Issuer and the Trustee receive proof satisfactory to each of them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant
to Section 2.07 hereof. 
 If by 10:00 a.m., New York City time, on a Redemption Date or the Maturity Date, the Paying
Agent holds U.S. legal tender sufficient to pay all of the principal and interest due on the Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue. 

Section 2.09. Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Issuer or any of its Affiliates shall be
considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are
so owned shall be so considered. The Issuer shall notify the Trustee, in writing, when it or any of its Affiliates repurchases or otherwise acquires Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired.


  
 -27-








 Section 2.10. Temporary Notes. 

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon receipt of
a written order of the Issuer in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of temporary Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary
Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate upon receipt of a
written order of the Issuer pursuant to Section 2.02 definitive Notes in exchange for temporary Notes. 
 Section 2.11.
Cancellation. 
 The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying
Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel and, at the written
direction of the Issuer, dispose of and deliver evidence of such disposal of all Notes surrendered for registration of transfer, exchange, payment or cancellation in accordance with their then existing procedures therefor. Subject to
Section 2.07 hereof, the Issuer may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a redemption or
satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. In no event shall the Trustee be required to destroy cancelled Notes.

 Section 2.12. Defaulted Interest. 
 The Issuer shall pay interest on overdue principal (including post-petition interest in a proceeding under Bankruptcy Law) at the rate of interest then borne by the Notes. The Issuer shall, to the extent
lawful, pay interest on overdue installments of interest (without regard to any applicable grace periods) at the rate of interest then borne by the Notes. 
 If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest to the Persons who are Holders
on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days
before the subsequent special record date, the Issuer shall mail to each Holder, as of a recent date selected by the Issuer, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of
defaulted interest, and interest payable on such defaulted interest, if any, to be paid. 
 Notwithstanding the foregoing, any
interest which is paid prior to the expiration of the 30-day period set forth in Section 6.01(a) hereof shall be paid to Holders as of the Record Date for the Interest Payment Date for which interest has not been paid. 

Section 2.13. Deposit of Moneys. 
 No later than 10:00 a.m., New York City time, on each Interest Payment Date, Redemption Date, Change of Control Payment Date, Offer Payment Date and Maturity Date, the Issuer shall have deposited with the
Paying Agent in immediately available funds U.S. legal tender sufficient to make payments, if any, due on such Interest Payment Date, Redemption Date, Change of Control Payment Date, Offer Payment Date or Maturity Date, as the case may be, in a
timely manner which permits the Trustee to remit payment to the Holders on such Interest Payment Date, Redemption Date, Change of Control Payment Date, Offer Payment Date or Maturity Date, as the case may be. The principal and interest on Global
Notes shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole Holder of the Global Notes represented thereby. The principal and interest on Notes in certificated form shall be payable in the
manner indicated in paragraph 2 of the Notes. 

  
 -28-








 Section 2.14. CUSIP Number. 

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

 Section 2.15. Book-Entry Provisions for Global Notes. 
 (a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and
(iii) bear legends as set forth in Section 2.17 hereof. 
 Members of, or participants in, the Depository
(“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository or under the Global Note, and the Depository may be treated by the Issuer, the Trustee and any agent
of the Issuer or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to
any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder. 

(b) Subject to the rules and procedures of the Depository, Certificated Notes shall be transferred to all beneficial owners in exchange
for their beneficial interests in Global Notes only if (i) the Depository (x) notifies the Issuer that it is unwilling or unable to continue as Depository for any Global Note and the Issuer fails to appoint a successor Depository within 90
days of such notice or (y) has ceased to be a clearing company registered under the Exchange Act and a successor Depository is not appointed by the Issuer within 90 days after becoming aware of such cessation, (ii) the Issuer, at its
option but subject to the procedures of the Depository, notifies the Trustee in writing that the Issuer elects to cause the issuance of Certificated Notes or (iii) an Event of Default has occurred and is continuing and the Depository notifies
the Trustee of its desire to exchange Global Notes for Certificated Notes. 
 (c) In connection with the transfer of Global
Notes as an entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the Issuer shall execute, and the Trustee shall, upon receipt of an authentication order
from the Issuer in the form of an Officers’ Certificate, authenticate and deliver, to each beneficial owner identified by the Depository in writing in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount
of Certificated Notes of authorized denominations. 
 (d) Any Certificated Note constituting a Restricted Security delivered in
exchange for an interest in a Global Note pursuant to paragraph (b) or (c) shall, except as otherwise provided by Section 2.16 hereof, bear the Private Placement Legend. 

(e) The Holder of any 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 which a Holder is entitled to take under this Indenture or the Notes. 
 Section 2.16.
Registration of Transfers and Exchanges.

Notes are presented to the Registrar or co-Registrar with a request: 
 (i) to register the transfer of the
Certificated Notes; or 

  
 -29-

Certificated Notes of other authorized denominations, 
 the Registrar or co-Registrar shall register the transfer or make the exchange as

Issuer, by the following additional information and documents, as applicable: 
 (A) if such Certificated Note
is being delivered to the Registrar or co-Registrar by a Holder for registration in the name of such Holder, without transfer, a certification to that effect (substantially in the form of Exhibit B hereto); or

(B) written instructions from the Holder thereof directing the Registrar or co-Registrar to make, or to direct the

 then the Registrar or co-Registrar shall cancel such Certificated Note and cause, or direct the Depository to cause, in accordance with the standing instructions and procedures existing between the
Depository and the Registrar or co-Registrar, the principal amount of Notes represented by the applicable Global Note to be increased accordingly. If no Global Note representing Notes held by Qualified Institutional Buyers or Persons acquiring Notes
in offshore transactions in reliance on Regulation S, as the case may be, is then outstanding, the Issuer shall issue and the Trustee shall, upon receipt of an authentication order of the Issuer executed by an Officer, authenticate such a Global
Note in the appropriate principal amount. 
 (c) Transfer and Exchange of Global Notes. The transfer and exchange of
Global Notes or beneficial interests therein shall be effected through the Depository in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depository therefor. Upon receipt by the

then the Registrar or co-Registrar will cause, in accordance with the standing instructions and procedures existing between the Depository and the Registrar or co-Registrar, the aggregate principal amount of the applicable Global Note to be reduced

Trustee shall, upon receipt of an authentication order from the Issuer executed by an Officer, authenticate a new Global Note of such type in principal amount equal to the principal amount of the interest to be transferred. 

(d) Transfer of a Beneficial Interest in a Global Note for a Certificated Note. (i) If Certificated Notes are to be issued in
exchange for Global Notes pursuant to Section 2.15(b), then upon receipt by the Registrar or co-Registrar of written instructions, or such other form of instructions as is customary for the Depository, from the Depository or its nominee on

under the Securities Act, delivery of a certification to that effect (substantially in the form of Exhibit B hereto) and, at the option of the Issuer, an Opinion of Counsel reasonably satisfactory to the Issuer to the effect that such
transfer is in compliance with the Securities Act; or 
 (F) if such beneficial interest is being transferred in
reliance on another exemption from the registration requirements of the Securities Act, a certification to that effect (substantially in the form of Exhibit B hereto) and, at the option of the Issuer, an Opinion of Counsel reasonably
satisfactory to the Issuer to the effect that such transfer is in compliance with the Securities Act, 
 then the Registrar or co-Registrar will
cause, in accordance with the standing instructions and procedures existing between the Depository and the Registrar or co-Registrar, the aggregate principal amount of the applicable Global Note to be reduced and, following such reduction, the
Issuer will execute and, upon receipt of an authentication order from the Issuer executed by an Officer, the Trustee will authenticate and deliver to the transferee a Certificated Note in the appropriate principal amount and series. 

(ii) Certificated Notes issued in exchange for a beneficial interest in a Global Note pursuant to this Section 2.16(d) hereof shall

co-Registrar shall deliver such Certificated Notes to the Persons in whose names such Certificated Notes are so registered. 

(e) Restrictions on Transfer and Exchange of Global Notes. Notwithstanding any other provisions of this Indenture, a Global Note
may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or
a nominee of such successor Depository. 
 (f) Private Placement Legend. Upon the transfer, exchange or replacement of
Notes, the Registrar or co-Registrar shall deliver only Notes that bear the Private Placement Legend unless, and the Trustee is hereby authorized to deliver Notes without the Private Placement Legend if, (i) the Resale Restriction Termination

the Private Placement Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this
Indenture. 
 None of the Issuer, the Trustee, any agent of the Issuer or the Trustee (including any Paying Agent or Registrar)
will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or beneficial owners of interests in any Global Note)
other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial

 REDEMPTION 
 Section 3.01. Notices to Trustee. 
 If the Issuer elects to redeem
Notes pursuant to paragraph 5 of the Notes, at least 60 days prior to the Redemption Date or during such other period as the Trustee may agree to, the Issuer shall notify the Trustee in writing of the Redemption Date, the principal amount of Notes
to be redeemed and the Redemption Price, if then determinable, and deliver to the Trustee an Officers’ Certificate stating that such redemption will comply with the conditions contained herein and in the Notes, as appropriate. 

Section 3.02. Selection of Notes to be Redeemed. 
 In the event that less than all of the Notes are to be redeemed at any time, selection of the Notes to be redeemed shall be made by the Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which such Notes are listed or, if such Notes are not then listed on a national security exchange, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate;
provided, however, that no Notes of a principal amount of $2,000 in original principal amount or less shall be redeemed in part; provided, further, that if a partial redemption is made with the proceeds of any Qualified
Equity Offering, selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depository), unless
such method is otherwise prohibited. A new Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon delivery of the original Note to the Paying Agent and cancellation of the original
Note. On and after the Redemption Date, interest will cease to accrue on Notes or portions thereof called for redemption as long as the Issuer has deposited with the Paying Agents funds in U.S. legal tender in satisfaction of the applicable
Redemption Price and amount of accrued interest, if any, payable pursuant to this Indenture. 
 Section 3.03. Notice of Redemption.

 Notice of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the Redemption Date to
each Holder 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 satisfaction and discharge of this Indenture. If any Note is
to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. 

  
 -34-








 The notice shall identify the Notes to be redeemed (including the CUSIP, ISIN or other
number(s) thereof) and shall state: 
 (1) the Redemption Date; 

(2) the Redemption Price (if then determinable and otherwise the method for its computation) and the amount of accrued
interest, if any, to be paid; 
 (3) that, if any Note is being redeemed in part, the portion of the principal
amount (equal to $2,000 in principal amount or any integral multiple of $1,000 in excess thereof) of such Note to be redeemed and that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion thereof will be issued; 
 (4) the name, address and telephone number of the Paying
Agent; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent at the address specified
to collect the Redemption Price plus accrued interest, if any; 
 (6) that, unless the Issuer defaults in making
the redemption payment, interest on Notes called for redemption ceases to accrue on and after the Redemption Date and the only remaining right of the Holders is to receive payment of the Redemption Price plus accrued interest to the Redemption Date
upon surrender of the Notes to the Paying Agent; 
 (7) the subparagraph of the Notes pursuant to which the
Notes called for redemption are being redeemed; and 
 (8) if fewer than all the Notes are to be redeemed, the
identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption. 

Section 3.04. Effect of Notice of Redemption. 
 Once the notice of redemption described in Section 3.03 hereof is mailed, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price, including any premium,
plus accrued interest to the Redemption Date, if any. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price, including any premium, plus accrued interest to the Redemption Date, if any; provided that if the
Redemption Date is after a Record Date and on or prior to the Interest Payment Date, the accrued interest shall be payable to the Holder of the redeemed Notes registered on the relevant Record Date. 

Section 3.05. Deposit of Redemption Price. 
 (a) No later than 10:00 a.m., New York City time, on each Redemption Date, the Issuer shall have deposited with the Paying Agent in immediately available funds U.S. legal tender sufficient to pay the
Redemption Price of and accrued interest on all Notes to be redeemed on that date. 
 (b) On and after any Redemption Date, if
U.S. legal tender sufficient to pay the Redemption Price of and accrued interest on Notes called for redemption shall have been made available in accordance with clause (a), the Notes called for redemption will cease to accrue interest and the only
right of the Holders of such Notes will be to receive payment of the Redemption Price of and, subject to the first proviso in Section 3.04, accrued and unpaid interest on such Notes to the Redemption Date. If any Note called for redemption
shall not be so paid, interest will continue to accrue and be paid, from the Redemption Date until such redemption payment is made, on the unpaid principal of the Note and any interest not paid on such unpaid principal, in each case, at the rate and
in the manner provided for in Section 2.12 hereof.

 Section 3.07. Tax Redemption. 

(a) If as a result of: 
 (i) any amendment to, or change in, the laws (or regulations or rulings promulgated thereunder) of any Relevant Taxing Jurisdiction which is announced and becomes effective after the Successor Date (or,

 (ii) any amendment to, or change in, the official application or official interpretation of the laws, regulations or rulings of any Relevant Taxing Jurisdiction which is announced and becomes effective
after the Successor Date (or, where a jurisdiction in question does not become a Relevant Taxing Jurisdiction until a later date, such later date), 
 a Foreign Successor Issuer would be obligated to pay, on the next date for any payment and as a result of that amendment or change, Additional Amounts or indemnification payments pursuant to
Section 4.24 hereof with respect to the Relevant Taxing Jurisdiction, which such Foreign Successor Issuer reasonably determines it cannot avoid by the use of reasonable measures available to it, then such Foreign Successor Issuer may redeem
all, but not less than all, of the Notes, at any time thereafter, upon not less than 30 nor more than 60 days’ notice to the Trustee and to each Holder of Notes to be redeemed, at a redemption price of 100% of their principal amount (or, if
such payments result from a permitted merger that constitutes a Change of Control, 101% of their principal amount), plus accrued and unpaid interest, if any, to the redemption date. 

Prior to the giving of any notice of redemption described in this paragraph, a Foreign Successor Issuer will deliver to the Trustee:

 (i) an Officers’ Certificate of such Foreign Successor Issuer stating that the obligation to pay the
Additional Amounts or indemnification payments cannot be avoided by such Foreign Successor Issuer’s taking reasonable measures available to it; and 
 (ii) a written opinion of independent legal counsel to such Foreign Successor Issuer of recognized standing to the effect that such Foreign Successor Issuer has or will become obligated to pay such
Additional Amounts or indemnification payments as a result of a change, amendment, official interpretation or application described above. 
 (b) A Foreign Successor Issuer will publish a notice of any optional redemption of the Notes described above in accordance with Section 3.03, 3.04 and 3.05 hereof. No such notice of redemption may be
given more than 60 days before the Foreign Successor Issuer first becomes liable to pay any Additional Amount or other payments under Section 4.24.

judgment of the Board of Directors of the Issuer or of the Board of Directors of any Subsidiary of the Issuer concerned, or of an Officer (or other agent employed by the Issuer or of any of its Subsidiaries) of the Issuer or any of its Subsidiaries
having managerial responsibility for any such property, desirable in the conduct of the business of the Issuer or any Subsidiary of the Issuer, and if such discontinuance or disposal is not adverse in any material respect to the Holders. 

(b) The Issuer shall maintain, and shall cause its respective Subsidiaries to maintain, insurance with responsible carriers against such
risks and in such amounts, and with such deductibles, retentions, self-insured amounts and co-insurance provisions, as are customarily carried by corporations operating assets of a similar nature in the same or similar localities, including property

Indebtedness. 
 (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, incur
any Indebtedness; provided that the Issuer or any Restricted Subsidiary may incur additional Indebtedness if, after giving effect thereto on a pro forma basis (including giving pro forma effect to the application of the proceeds therefrom),

an aggregate principal amount not to exceed at any time outstanding the greater of (a) $50.0 million and (b) 3.0% of the Issuer’s Consolidated Tangible Assets as determined at the time of incurrence. 

For purposes of determining compliance with this covenant, in the event that an item of Indebtedness meets the criteria of more than one
of the categories of Permitted Indebtedness described in clauses (1) through (17) above or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify such item of Indebtedness
and may divide and classify such Indebtedness in more than one of the types of Indebtedness described, except that Indebtedness outstanding under the Credit Agreement on the Issue Date after giving effect to the application of the proceeds from the
issuance of the Notes shall be deemed to have been incurred under clause (1) above, and may later reclassify any item of Indebtedness described in clauses (1) through (17) above (provided that at the time of reclassification it
meets the criteria in such category or categories). In addition, for purposes of determining any particular amount of Indebtedness under this covenant, guarantees, Liens or letter of credit obligations supporting Indebtedness otherwise included in
the determination of such particular amount shall not be included so long as incurred by a Person that could have incurred such Indebtedness. 
 For the purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar-equivalent principal amount of
such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier of the date that 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-denominated restriction to be
exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing
Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. The principal amount of any Indebtedness incurred to refinance other 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 Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 

Notwithstanding any other provision of this Section 4.10, in no event shall the reclassification of any lease or other liability as
indebtedness due to a change in accounting principles after the Issue Date be deemed to be an incurrence of Indebtedness. 
 Section 4.11.
Limitations on Restricted Payments. 
 (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, make any Restricted Payment if at the time of such Restricted Payment: 
 (1) a Default
shall have occurred and be continuing or shall occur as a consequence thereof; 
 (2) after giving pro forma
effect to such Restricted Payment as if such Restricted Payment had been made at the beginning of the applicable Four-Quarter Period, the Issuer is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness)

 Section 4.12. Limitations on Asset Sales. 

(a) The Issuer will not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

 (1) the Issuer or such Restricted Subsidiary receives consideration at least equal to the Fair Market Value
(such Fair Market Value to be determined at the time of contractually agreeing to such Asset Sale or, in circumstances where the Issuer or such Restricted Subsidiary grants a third party the right to purchase an asset, the date of such grant) of the
assets included in such Asset Sale; and 
 (2) (a) at least 75% of the total consideration in such Asset Sale
consists of cash or Cash Equivalents or (b) the Fair Market Value of all forms of consideration other than cash and Cash Equivalents received for all Asset Sales since the Issue Date does not exceed in the aggregate 10.0% of the Consolidated
Tangible Assets of the Issuer at the time such determination is made. 
 For purposes of clause (2), the following shall be
deemed to be cash: 
 (A) the amount (without duplication) of any Indebtedness (other than Subordinated
Indebtedness, Disqualified Equity Interests, or Indebtedness owed to an Affiliate of the Issuer) of the Issuer or such Restricted Subsidiary that is delivered to the Issuer or such Restricted Subsidiaries as consideration for such Asset Sale and
promptly retired or extinguished without payment, or that is expressly assumed by the transferee of any such assets pursuant to (i) a written novation agreement that releases the Issuer or such Restricted Subsidiary from further liability
therefor or (ii) an assignment agreement that includes, in lieu of such a release, the agreement of the transferee or its parent company to indemnify and hold harmless the Issuer or such Restricted Subsidiary from and against any loss,
liability or cost in respect of such assumed liability, 
 (B) the amount of any obligations received from such
transferee that are within 180 days after such Asset Sale converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash actually so received), and 

(C) the Fair Market Value of (i) any assets (other than securities) received by the Issuer or any Restricted
Subsidiary to be used by it in a Permitted Business, (ii) Equity Interests acquired in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the
acquisition of such Person by the Issuer or a Restricted Subsidiary or (iii) a combination of (i) and (ii). 
 (b) If
at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received
with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with
this Section 4.12. 
 (c) Any Asset Sale pursuant to a condemnation, appropriation or other similar taking, including by
deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a Permitted Lien or exercise by the related lienholder of rights with respect thereto, including by deed or assignment in lieu of foreclosure, shall not be required
to satisfy the conditions set forth in subclauses (1) and (2) of clause (a) of this Section 4.12. 
 (d)
Notwithstanding the foregoing, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the
provisions of Section 4.12(a) on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation. 

  
 -44-








 (e) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such
Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply all or any of the Net Available Proceeds therefrom to: 
 (i) prepay, repay, redeem, defease or purchase secured Indebtedness of the Issuer or a Restricted Subsidiary (other than Disqualified Equity Interests, Subordinated Indebtedness or Indebtedness owed to
the Issuer or an Affiliate of the Issuer); 
 (ii) satisfy all mandatory repayment obligations under Credit
Facilities arising by reason of such Asset Sale; 
 (iii) repay any Indebtedness which was secured by the assets
sold in such Asset Sale; and/or 
 (iv) (A) make any capital expenditure or otherwise invest all or any part of
the Net Available Proceeds thereof in the purchase of assets (other than securities) to be used by the Issuer or any Restricted Subsidiary in the Permitted Business, (B) acquire Qualified Equity Interests in a Person that is a Restricted
Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such acquisition or (C) a combination of (A) and (B). 

(f) The amount of Net Available Proceeds not applied or invested as provided in the preceding clause (e) shall constitute
“Excess Proceeds.” 
 (g) When the aggregate amount of Excess Proceeds equals or exceeds $30.0 million, the
Issuer shall be required to make an offer to purchase from all Holders and, if applicable, purchase or redeem (or make an offer to do so) any Pari Passu Indebtedness of the Issuer the provisions of which require the Issuer to purchase or redeem such
Indebtedness with the proceeds from any Asset Sales (or offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal to the amount of such Excess Proceeds as follows: 

(1) the Issuer will (a) make an offer to purchase (a “Net Proceeds Offer”) to all Holders in
accordance with the procedures set forth in this Indenture, and (b) purchase or redeem (or make an offer to do so), pro rata in proportion to the respective principal amounts of the Notes and such other Indebtedness required to be
purchased or redeemed, the maximum principal amount of Notes and Pari Passu Indebtedness that may be purchased or redeemed out of the amount (the “Payment Amount”) of such Excess Proceeds; 

(2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the principal amount of the Notes
tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the “Offered Price”), in accordance with the procedures set forth in this Indenture,
and the purchase or redemption price for such Pari Passu Indebtedness (the “Pari Passu Indebtedness Price”) shall be as set forth in the related documentation governing such Indebtedness; 

(3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders thereof exceeds the pro rata
portion of the Payment Amount allocable to the Notes, Notes to be purchased will be selected on a pro rata basis; and 
 (4) upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

 (h) To the extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer and the
aggregate Pari Passu Indebtedness Price paid to the holders of such Pari Passu Indebtedness is less than the Payment Amount relating thereto (such shortfall constituting a “Net Proceeds Deficiency”), the Issuer may use the Net
Proceeds Deficiency, or a portion thereof, for any purposes not otherwise prohibited by the provisions of this Indenture. 

  
 -45-








 (i) Notwithstanding the foregoing, the sale, conveyance or other disposition of all or
substantially all of the assets of the Issuer and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of Section 4.15 and/or the provisions of Article 5 and not by the provisions of this Section 4.12.

 (j) Upon the commencement of a Net Proceeds Offer, the Issuer must send, by first-class mail, a notice to
each Holder, with a copy to the Trustee, which notice shall govern the terms of such Offer. Such notice shall state: 
 (1) that such Offer is being made pursuant to this Section 4.12; 
 (2) the Offered Price and the Offer Payment Date; 
 (3) that any
Note not tendered shall continue to accrue interest; 
 (4) that, unless the Issuer defaults in the payment of
the Offered Price, any Notes accepted for payment pursuant to such Offer shall cease to accrue interest after the Offer Payment Date; 
 (5) that such Offer shall remain open for at least 20 Business Days or for such longer period as is required by law and that Holders accepting the offer to have their Notes purchased pursuant to such
Offer shall be required to surrender the Notes, with the form entitled “Option of the Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business
on the third Business Day preceding the Offer Payment Date; 
 (6) that Holders shall be entitled to withdraw
their acceptance if the Paying Agent receives, not later than the close of business on the third Business Day preceding the Offer Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal
amount of the Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have such Notes purchased; 
 (7) that Holders whose Notes are being purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered; 

(8) any other procedures that a Holder must follow to accept such Offer or effect withdrawal of such acceptance; and

 (9) the name and address of the Paying Agent. 

(k) The Issuer shall publicly announce the results of a Net Proceeds Offer as soon as practicable after the related Offer Payment Date.

 (l) On the Offer Payment Date, the Issuer shall, to the extent lawful, (1) accept for payment all Notes or portions of
Notes properly tendered pursuant to the Net Proceeds Offer, or such lesser amount thereof as the Issuer is required to purchase pursuant to this Section 4.12, (2) deposit with the Paying Agent an amount equal to the Offered Price in
respect of all Notes or portions of Notes properly tendered and accepted for payment, and (3) 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 Issuer. 
 (m) After the Issuer’s satisfaction of its
obligations under the preceding clause (l), the Paying Agent shall as promptly as practicable mail to each Holder of Notes properly tendered the Offered Price for such Notes, and the Trustee shall as promptly as practicable authenticate and mail to
each Holder a new Note in principal amount equal to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000.


  
 -46-








 The Issuer shall comply with applicable tender offer rules, including the requirements of
Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with this
Section 4.12, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.12 by virtue of this compliance. 

Section 4.13. Limitations on Transactions with Affiliates. 
 (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, in one transaction or a series of related transactions involving aggregate payments or consideration in
excess of $1.0 million, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an
“Affiliate Transaction”), unless: 
 (1) such Affiliate Transaction is on terms that are not
materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that could reasonably be expected to have been obtained in a comparable transaction at such time on an arm’s-length basis by the Issuer or that Restricted
Subsidiary from a Person that is not an Affiliate of the Issuer or that Restricted Subsidiary; and 
 (2) the
Issuer delivers to the Trustee with respect to any Affiliate Transaction involving aggregate value in excess of $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and a

 (3) the entering into of a tax sharing agreement, or payments
pursuant thereto, between the Issuer and/or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such
Subsidiaries are part of a consolidated group for tax purposes to be used by such Person to pay taxes, and which payments by the Issuer and the Restricted Subsidiaries are not in excess of the tax liabilities that would have been payable by them on
a stand-alone basis; 
 (4) any Permitted Investments; 

(5) any Restricted Payments which are made in accordance with Section 4.11; 

(6) (x) any agreement in effect on the Issue Date, as in effect on the Issue Date or as thereafter amended or

to in the immediately preceding clause (x); 
 (7) any transaction with a Person (other than an Unrestricted
Subsidiary) which would constitute an Affiliate of the Issuer solely because the Issuer or a Restricted Subsidiary owns an equity interest in or otherwise controls such Person;

Subsidiary is Qualified Equity Interests of the Issuer or (b) the issuance or sale of any Qualified Equity Interests of the Issuer;

transaction is not entered into in contemplation of such event); and 
 (12) dividends and distributions to the
Issuer or a Restricted Subsidiary by any Unrestricted Subsidiary. 
 Section 4.14. Limitation on Liens.

suffer to exist any Lien (other than Permitted Liens) of any nature whatsoever against any assets of the Issuer or any Restricted Subsidiary (including Equity Interests of a Restricted Subsidiary), whether owned at the Issue Date or thereafter
acquired, which Lien secures Indebtedness, unless the Notes are equally and ratably secured with (or prior to) such Indebtedness secured by such Lien. 
 Section 4.15. Change of Control. 
 (a) Upon the occurrence of any
Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described in paragraph 5 of the Notes, each Holder will have the right to require that the Issuer purchase all or any portion
(equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes for a cash price (the “Change of Control Purchase Price”) equal to 101.0% of the principal amount of the Notes to be purchased, plus

obligations under the provisions of this Section 4.15 by virtue thereof.

Person so acquired; 

  
 -50-








 (8) any other agreement governing Indebtedness or other obligations entered
into after the Issue Date that contains encumbrances and restrictions that in the good faith of the Issuer are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that
Restricted Subsidiary pursuant to agreements in effect on the Issue Date; 
 (9) customary provisions in
partnership agreements, limited liability company organizational governance documents, joint venture agreements, shareholder agreements and other similar agreements entered into in the ordinary course of business that restrict the transfer of
ownership interests in or assets of such partnership, limited liability company, joint venture, corporation or similar Person;

encumbrance or restriction applicable only to a Foreign Restricted Subsidiary in agreements entered into in connection with Indebtedness incurred by such Foreign Restricted Subsidiary in compliance with subclause (14) of Section 4.10(b);

 (13) Indebtedness incurred or Equity Interests issued by any Restricted Subsidiary; provided that the
restrictions contained in the agreements or instruments governing such Indebtedness or Equity Interests (a) either (i) apply only in the event of a payment default or a default with respect to a financial covenant in such agreement or
instrument or (ii) will not materially affect the Issuer’s ability to pay all principal and interest on the Notes, as determined in good faith by the Chief Financial Officer of the Issuer, whose determination shall be conclusive and
(b) are not materially more disadvantageous to the Holders of the Notes than is customary in comparable financings (as determined by the Chief Financial Officer of the Issuer, whose determination shall be conclusive); 

(14) any encumbrance or restriction existing under Hedging Obligations permitted under this Indenture; and 

(15) any encumbrances or restrictions imposed by any amendments, refinancings, modifications, renewals, restatements,
increases, supplements or replacements of the contracts, instruments or obligations referred to in clauses (1) through (14) above; provided that such amendments, refinancings, modifications, renewals, restatements, increases,
supplements or replacements are, in the good faith judgment of the Issuer, no more materially restrictive with respect to such encumbrances and restrictions than those prior to such amendment or refinancing. 

Section 4.17. [Reserved]. 

Section 4.18. Conduct of Business. 
 The Issuer shall engage, and shall cause its Restricted Subsidiaries to engage, only in businesses that, when considered together as a single enterprise, are primarily the Permitted Business. 

Section 4.19. Limitations on Designation of Unrestricted Subsidiaries. 

(a) The Issuer may designate any Subsidiary (including any newly formed or newly acquired Subsidiary) of the Issuer as an
“Unrestricted Subsidiary” under this Indenture (a “Designation”) only if: 
 (1) no
Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and 

  
 -51-








 (2) the Issuer would be permitted to make, at the time of such Designation,
(a) a Permitted Investment or (b) an Investment pursuant to clause (a) of Section 4.11, in either case in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s proportionate
interest in such Subsidiary on such date. 
 (b) No Subsidiary shall be Designated as an “Unrestricted Subsidiary”
unless: 
 (1) all of the Indebtedness of such Subsidiary and its Subsidiaries shall, at the time of
Designation, consist of Non-Recourse Debt, except any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or
any Restricted Subsidiary, and except for any Contingent Obligations of the Issuer or any Restricted Subsidiary in respect of Indebtedness of such Unrestricted Subsidiary that is permitted as both an incurrence of Indebtedness and an Investment (in
each case in an amount equal to the amount of such Indebtedness so guaranteed) permitted by Sections 4.10 and 4.11); 
 (2) on the date such Subsidiary is Designated an Unrestricted Subsidiary, such Subsidiary is not party to any agreement, contract, arrangement or understanding (other than Contingent Obligations permitted
under clause (1) above) with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding, taken as a whole, are not materially less favorable to the Issuer or the Restricted Subsidiary than
those that could reasonably be expected to have been obtained at the time from Persons who are not Affiliates of the Issuer, as determined in good faith by the Issuer; 

(3) such subsidiary is a Person with respect to which neither the Issuer nor any Restricted Subsidiary has any direct or
indirect obligation (a) to subscribe for additional Equity Interests of such Person or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results (in each
case other than Contingent Obligations permitted under clause (1) above); and 
 (4) such subsidiary has
not guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Issuer or any Restricted Subsidiary, except for any pledge of the Equity Interests of such Unrestricted Subsidiary to secure Indebtedness of the
Issuer or any Restricted Subsidiary. 
 (c) If, at any time, any Unrestricted Subsidiary fails to meet the preceding
requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by
a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under Section 4.10 or the Lien is not permitted under Section 4.14, the Issuer shall be in default of the applicable Section. 

(d) The Issuer may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a “Redesignation”) only if:

 (1) no Default shall have occurred and be continuing at the time of and after giving effect to such
Redesignation; and 
 (2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary outstanding
immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture. 
 (e) All Designations and Redesignations must be evidenced by resolutions of the Board of Directors of the Issuer and delivered to the Trustee certifying compliance with the foregoing provisions.

 Section 4.20. Additional Note Guarantees. 
 If, after the Issue Date, (a) the Issuer or any Restricted Subsidiary shall acquire or create another Domestic Restricted Subsidiary, or (b) any Unrestricted Subsidiary is Redesignated a
Domestic Restricted Subsidiary, and (in each such case) such Domestic Restricted Subsidiary guarantees any Indebtedness under any Credit Facility, then the Issuer shall, within 15 Business Days, cause such Domestic Restricted Subsidiary to:


  
 -52-








 (1) execute and deliver to the Trustee a supplemental indenture
substantially in the form prescribed by this Indenture pursuant to which such Domestic Restricted Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and this Indenture; and 

(2) deliver to the Trustee the Opinion of Counsel required by Section 10.07 hereof. 

Section 4.21. Limitations on Layering Indebtedness. 
 (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, incur any Indebtedness that is or purports to be by its terms (or by the terms of any agreement
governing such Indebtedness) subordinated in right of payment to any other Indebtedness of the Issuer or of such Restricted Subsidiary, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing
such Indebtedness) made expressly subordinate in right of payment to the Notes or the Note Guarantee of such Restricted Subsidiary, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of the
Issuer or such Restricted Subsidiary, as the case may be. 
 (b) For purposes of the foregoing, no Indebtedness will be deemed
to be subordinated in right of payment to any other Indebtedness of the Issuer or any Restricted Subsidiary solely by virtue of being unsecured or secured by a Permitted Lien or by virtue of the fact that the holders of such Indebtedness have
entered into intercreditor agreements or other arrangements giving one or more of such holders priority over the other holders in the collateral held by them or other payments among them. 
 Section 4.22. [Reserved]. 
 Section 4.23. Suspension of Covenants.

 (a) During any period of time that the Notes have a Moody’s rating of “Baa3” or higher and an S&P rating
of “BBB-” or higher (each, an “Investment Grade Rating”) and no Default has occurred and is then continuing, the Issuer and the Restricted Subsidiaries will not be subject to the following covenants: Section 4.10,
Section 4.11, Section 4.12, Section 4.13, Section 4.16, Section 4.18, Section 4.20, Section 4.21 and Section 5.01(a)(3) (collectively, the “Suspended Covenants”). 

(b) In the event that the Issuer and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a
result of the preceding sentence and, subsequently, one or both of the Rating Agencies, as applicable, withdraws its ratings or downgrades the ratings assigned to the Notes such that the Notes do not have an Investment Grade Rating, then the Issuer
and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants, it being understood that no actions taken by (or omissions of) the Issuer or any of its Restricted Subsidiaries during the suspension period shall
constitute a Default or an Event of Default under the Suspended Covenants. Furthermore, after the time of reinstatement of the Suspended Covenants upon such withdrawal or downgrade, calculations with respect to Restricted Payments will be made in
accordance with the terms of the covenant described above under Section 4.11 as though such covenant had been in effect during the entire period of time from the Issue Date. 
 Section 4.24. Payment of Additional Amounts by a Foreign Successor Issuer. 
 (a) All payments made under or with respect to the Notes or any Note Guarantee by any Foreign Successor Issuer or any Guarantor of a Foreign Successor Issuer (each such person, a “Payor”)
will be made free and clear of any withholding or deduction for or on account of any tax, duty, levy, impost, assessment or other governmental charge of whatever nature (collectively, “Tax”) imposed or levied by or on behalf of any
jurisdiction in which such Payor is organized, resident or doing business for tax purposes or from or through which such Payor (or any of its agents) makes any payment on the Notes or any Note Guarantee or any department or political subdivision of
any of the foregoing (each, a “Relevant Taxing Jurisdiction”), unless such Payor or other applicable withholding 

  
 -53-








 agent is required to withhold or deduct Taxes by law. For the avoidance of doubt, a Relevant Taxing
Jurisdiction shall not include the United States, any state thereof or the District of Columbia. If a Payor or other applicable withholding agent is required by law to withhold or deduct any amount for or on account of Taxes of a Relevant Taxing
Jurisdiction from any payment made under or with respect to the Notes or any Note Guarantee, the Payor, subject to the exceptions listed below, will pay additional amounts (“Additional Amounts”) as may be necessary to ensure that
the net amount received by each Holder of the Notes after such withholding or deduction (including withholding or deduction attributable to Additional Amounts payable hereunder) will not be less than the amount the Holder would have received if such
Taxes had not been withheld or deducted. 
 (b) A Payor will not, however, pay Additional Amounts to a Holder or beneficial
owner of Notes: 
 (i) to the extent the Taxes giving rise to such Additional Amounts would not have been
imposed but for the Holder’s or beneficial owner’s present or former connection with the Relevant Taxing Jurisdiction (other than any connection resulting from the acquisition, ownership, holding or disposition of Notes, the receipt of
payments thereunder or under any Note Guarantee and/or the exercise or enforcement of rights under any Notes or any Note Guarantee); 
 (ii) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the failure of the Holder or beneficial owner of Notes, following the Payor’s written request
address to the Holder, to the extent such Holder or beneficial owner is legally eligible to do so, to comply with any certification, identification, information or other reporting requirements, whether required by statute, treaty, regulation or
administrative practice of a Relevant Taxing Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Relevant Taxing Jurisdiction (including, without limitation, a
certification that the Holder or beneficial owner is not resident in the Relevant Taxing Jurisdiction); 
 (iii)
with respect to any estate, inheritance, gift, sales or any similar Taxes; 
 (iv) if such Holder is a fiduciary
or partnership or person other than the sole beneficial owner of such payment and the Taxes giving rise to such Additional Amounts would not have been imposed on such payment had the Holder been the beneficiary, partner or sole beneficial owner, as
the case may be, of such Notes (but only if there is no material cost or expense associated with transferring such Notes to such beneficiary, partner or sole beneficial owner and no restriction on such transfer that is outside the control of such
beneficiary, partner or sole beneficial owner); 
 (v) to the extent the Taxes giving rise to such Additional
Amounts would not have been imposed but for the presentation by the Holder of any Notes, where presentation is required, for payment on a date more than 30 days after the date of which payment became due and payable or the date on which payment
thereof is duly provided for, whichever occurs later; 
 (vi) with respect to any withholding or deduction that
is imposed pursuant to the European Council Directive on the taxation of savings income which was adopted by the ECOFIN Council on June 3, 2003 or any law implementing or complying with, or introduced in order to conform to such directive (the
“EU Savings Tax Directive”) or is required to be made pursuant to the Agreement between the European Community and the Swiss Confederation dated October 26, 2004 providing for measures equivalent to those laid down in the EU
Savings Tax Directive (the “EU-Swiss Savings Tax Agreement”) or any law or other governmental regulation implementing or complying with, or introduced in order to conform to, such agreement; 

(vii) with respect to any tax that is payable other than by deduction or withholding at source; or 

(viii) any combination of items (i), (ii), (iii), (iv), (v), (vi) and (vii). 

  
 -54-








 (c) A Payor will (i) make any such withholding or deduction required by applicable law
and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Payor will make reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted
or withheld from each Relevant Taxing Jurisdiction imposing such Taxes. The Payor will provide to the Trustee, within a reasonable time after the date the payment of any Taxes so deducted or withheld are due pursuant to applicable law, either a
certified copy or tax receipts evidencing such payment, or, if such tax receipts are not reasonably available to the Payor, such other documentation that provides reasonable evidence of such payment by the Payor. 

(d) The Payor will deliver to the Trustee any Additional Amounts payable together with an Officers’ Certificate stating that such
Additional Amounts will be payable prior to the date on which such payments will be made, and will include such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date. Any such Officers’
Certificate will be delivered a reasonable time in advance of when the payments in question are required to be made. The Payor will promptly publish a notice in accordance with Section 11.02 hereof stating that such Additional Amounts will be
payable and describing the obligation to pay such amounts. 
 (e) The Payors, jointly and severally, will reimburse the Holders
of the Notes, upon written request of such Holder of the Notes and appropriate proof of payment for the amount of (i) any Taxes levied or imposed by a Relevant Taxing Jurisdiction and payable by such Holder or the applicable beneficiary in
connection with payments made under or with respect to the Notes held by such Holder or any Note Guarantee; and (ii) any Taxes levied or imposed with respect to any reimbursement under the foregoing clause (i) or this clause (ii), so that
the net amount received by the beneficial owner after such reimbursement will not be less than the net amount such beneficial owner would have received if the Taxes giving rise to the reimbursement described in clauses (i) and/or (ii) had
not been imposed, provided, however, that the indemnification obligation provided for in this Section 4.24(e) shall not extend to Taxes imposed for which the Holder or beneficial owner would not have been eligible to receive
payment of Additional Amounts hereunder by virtue of clauses (i) through (viii) of Section 4.24(b) hereof, or to the extent such Holder or beneficial owner received Additional Amounts with respect to such payments. 

(f) In addition, a Foreign Successor Issuer will pay any stamp, issue, registration, court, documentary, excise or other similar taxes,
charges and duties (including interest, additions to tax and penalties with respect thereto) imposed by any Relevant Taxing Jurisdiction at any time on or after the date on which the Foreign Successor Issuer becomes a Foreign Successor Issuer (the
“Successor Date”) in respect of the execution, issuance, registration or delivery of the Notes, any Note Guarantee or any other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any
Relevant Taxing Jurisdiction at any time on or after the Successor Date as a result of, or in connection with, (i) any payments made pursuant to the Notes, any Note Guarantee or any other such document or instrument referred to thereunder
and/or (ii) the enforcement of the Notes any Note Guarantee or any other such document or instrument referred to thereunder. 
 (g) The obligations described under this Section 4.24 will survive any termination, defeasance or discharge of this Indenture and will apply mutatis mutandis to any successor Person, to any
Payor, and to any jurisdiction (other than the United States, any state thereof or the District of Columbia) in which such successor is organized, resident or doing business for Tax purposes or any jurisdiction from or through which payment is made
by such successor or its agents. 
 (h) Whenever this Indenture refers to, in any context, the payment of principal, premium, if
any, interest or any other amount payable under or with respect to any Note or under any Note Guarantee, such reference includes the payment of Additional Amounts or indemnification payments that would be payable pursuant to this Section 4.24,
if applicable.

or the Successor, as the case may be, would be equal to or greater than such ratio for the Issuer immediately prior to such transaction. 
 (b) For purposes of this Section 5.01, any Indebtedness of the Successor which was not Indebtedness of the Issuer immediately prior to the transaction shall be deemed to have been incurred in
connection with such transaction to the extent such Indebtedness remains outstanding immediately after giving effect to such transaction. 
 (c) Except as provided in Section 10.06, no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, unless: 

(1) either:

a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries, the Equity Interests of which constitute all or substantially all of the properties and assets of the

Notwithstanding the foregoing, (i) any Restricted Subsidiary may consolidate with, merge with or into or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to the Issuer or another

 Notwithstanding the foregoing, Section 5.01(a)(3) will not prohibit the Issuer from entering into a transaction as a result of which the Issuer is reorganized in a Permitted Jurisdiction. 

Section 5.02. Successor Person Substituted. 
 Upon any consolidation, combination or merger of the Issuer or a Guarantor, or any transfer of all or substantially all of the assets of the Issuer in accordance with Section 5.01, in which the

transfer, disposition or assignment is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer or such Guarantor under this Indenture, the Notes and the Note Guarantees with the same effect as if such

indenture or other instrument or agreement under which there may be issued or by which there may be secured or evidenced Indebtedness for borrowed money by the Issuer or any Restricted Subsidiary, whether such Indebtedness now exists or is incurred
after the Issue Date, which default (A) is caused by a failure to pay at final maturity principal on such Indebtedness within the applicable express grace period and any extensions thereof (a “payment default”) or
(B) results in the acceleration of such Indebtedness prior to its express final maturity (which acceleration is not rescinded, annulled or otherwise cured within 30 days of receipt by the Issuer or such Restricted Subsidiary of notice of any
such acceleration), and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other Indebtedness with respect to which an event described in clause (A) or (B) has occurred and is continuing,

 The term “Bankruptcy Law” means Title 11, U.S. Code or any similar Federal,
state or foreign law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 
 Section 6.02. Acceleration. 
 If an Event of Default (other than an
Event of Default specified in Section 6.01(g) or (h) with respect to the Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25% in aggregate
principal amount of the Notes then outstanding, by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. Upon such declaration of
acceleration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable upon the earlier of (x) the final maturity (after giving effect to any applicable grace period or extensions thereof)
or an acceleration of any Indebtedness under any Credit Facility prior to the express final stated maturity thereof and (y) five Business Days after the collateral agent under each Credit Facility receives the acceleration declaration, but,
only if such Event of Default is then continuing; provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes
may rescind and annul such acceleration if: 
 (1) the rescission would not conflict with any judgment or
decree; 
 (2) all Events of Default, other than nonpayment of principal or interest that has become due solely
because of the acceleration, have been cured or waived; 
 (3) to the extent the payment of such interest is
lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; 

(4) the Issuer has paid all sums paid or advanced by the Trustee hereunder and its reasonable compensation and reimbursed
the Trustee for its expenses, disbursements and advances and those of its agents and counsel; and 
 (5) in the
event of the cure or waiver of an Event of Default of the type described in Section 6.01(g) or (h) above, the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or
waived. 
 No such rescission shall affect any subsequent Default or impair any right consequent thereto. If an Event of Default
specified in Section 6.01(g) or (h) occurs with respect to the Issuer and is continuing, then, to the extent permitted by applicable law, all unpaid principal of and accrued and unpaid interest on all of the outstanding Notes shall ipso
facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 

Section 6.03. Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of and interest on the Notes or to
enforce the performance of any provision of the Notes or this Indenture and may take any necessary action requested of it as Trustee to settle, compromise, adjust or otherwise conclude any proceedings to which it is a party. 

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. No remedy is exclusive of any
other remedy. All available remedies are cumulative to the extent permitted by law.

 Section 6.04. Waiver of Past Defaults and Events of Default. 

Subject to Sections 2.09, 6.02, 6.07 and 8.02 hereof, the Holders of a majority in aggregate principal amount of the Notes then
outstanding have the right to waive past Defaults under this Indenture except a Default or Event of Default in the payment of the principal of or interest on any Note as specified in clauses (a) and (b) of Section 6.01 or in respect
of a covenant or a provision which cannot be modified or amended without the consent of all Holders as provided for in Section 8.02. The Issuer shall deliver to the Trustee an Officers’ Certificate stating that the requisite percentage of
Holders have consented to such waiver. In case of any such waiver, the Issuer, the Trustee and the Holders shall be restored to their former positions and rights hereunder and under the Notes, respectively. This paragraph of this Section 6.04
shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. 

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 this Indenture, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto. 
 Section 6.05. Control by Majority. 
 Subject to Section 2.09
hereof, the Holders of a majority in aggregate principal amount of the outstanding Notes have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee by this Indenture. The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of another Holder not taking
part in such direction, and the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, determines that the action so directed may not lawfully be taken or if the Trustee in good faith shall, by
a Trust Officer, determine that the proceedings so directed may involve it in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. In the event the
Trustee takes any action or follows any direction pursuant to this Indenture, the Trustee shall be entitled to indemnification reasonably satisfactory to it against any loss or expense caused by taking such action or following such direction. This
Section 6.05 shall be in lieu of Section 316(a)(1)(A) of the TIA, and such Section 316(a)(1)(A) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. 

Section 6.06. Limitation on Suits. 
 (a) Subject to Section 6.07 below, no Holder shall have any right to institute any proceeding with respect to this Indenture or any remedy thereunder unless: 

(1) such Holder has given the Trustee written notice of a continuing Event of Default; 

(2) the Holders of at least 25% in aggregate principal amount of outstanding Notes have made a written request to the
Trustee to pursue the remedy; 
 (3) such Holder or Holders offer to the Trustee indemnity satisfactory to the
Trustee against any costs, liability or expense; 
 (4) the Trustee fails to institute such proceeding within 60
days after receipt of the request and the offer of indemnity; and 
 (5) the Trustee has not received directions
inconsistent with such written request during such 60-day period by the Holders of a majority in aggregate principal amount of the outstanding Notes. 
 (b) However, such limitations do not apply to the right of any Holder of a Note to receive payment of the principal of, or interest on, such Note or to bring suit for the enforcement of any such payment,
on or after the due date expressed in the Notes, which right will not be impaired or affected without the consent of the Holder.

 Section 6.07. Rights of Holders To Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of or accrued interest on
any Note held by such Holder on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected
without the consent of the Holder. 
 Section 6.08. Collection Suit by Trustee. 

If an Event of Default occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust
against the Issuer (or any other obligor on the Notes) for the whole amount of unpaid principal and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and interest
on overdue installments of interest, in each case at the rate set forth in Section 4.01 hereof, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. 
 Section 6.09. Trustee May File Proofs of Claim. 

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other obligor on the
Notes), its creditors or its property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same after deduction of its charges and expenses to the
extent that any such charges and expenses are not paid out of the estate in any such proceedings 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 7.07 hereof. 
 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 or reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceedings. 
 Section 6.10. Priorities. 

Any money collected by the Trustee pursuant to this Article and any other money or property distributable in respect of the Issuer’s
obligations under this Indenture after an Event of Default shall be applied in the following order: 
 FIRST: to
the Trustee (including any predecessor Trustee) for amounts due under Section 7.07 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: if the Holders are forced to proceed against the Issuer or any Guarantor directly without the
Trustee, to Holders for their collection costs; 
 THIRD: to Holders for amounts due and unpaid on the Notes for
principal and interest as to each, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes; and 
 FOURTH: to the Issuer or, to the extent the Trustee collects any amounts from any Guarantor, to such Guarantor. 

  
 -61-








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

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or
omitted by it as 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.07 hereof or a suit by Holders of more than 10% in principal amount of the Notes then outstanding. 

ARTICLE 7 

TRUSTEE 
 Section 7.01.
Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the
rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise thereof as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates (including Officers’ Certificates) or opinions (including Opinions of Counsel) furnished to the
Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions which are specifically required to be delivered to the Trustee by any provision of this Indenture to determine in good
faith whether or not they conform to the requirements of this Indenture. 
 (c) Notwithstanding anything to the contrary herein
contained, the Trustee may not be relieved from liability for its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, except that:

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 6.05 hereof. 
 (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 

(e) Whether or not herein expressly provided, every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), (c) and (d) of this Section 7.01.

instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee makes such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer and
shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 
 (i) The rights,
privileges, protections, immunities and benefits given to the Trustee in this Indenture, including, without limitation, its right to be indemnified and any limitations on its duties and liabilities under this Indenture, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder (including its capacity as Registrar, Paying Agent and agent for services of notices and demands), and each agent, custodian and other Person employed to act hereunder. 

(j) The permissive right of the Trustee to take or refrain from taking any actions enumerated in this Indenture shall not be construed as
a duty. 
 (k) The Trustee has no duty to determine whether the Issuer and the Guarantors are in compliance with the terms of
the Credit Agreement or any other Credit Facility. 
 Section 7.02. Rights of Trustee. 

Subject to Section 7.01 hereof: 
 (a) The Trustee may conclusively rely on any document reasonably believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter
stated in the document. 
 (b) Before the Trustee acts or refrains from acting with respect to any matters
contemplated by this Indenture or the Notes it may consult with counsel and may require an Officers’ Certificate or an Opinion of Counsel, or both, which shall conform to the provisions of Section 11.05 hereof. The Trustee shall be
protected and shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion. The Trustee may also consult with counsel on any matter relating to this Indenture or the Notes, and the Trustee

it takes or omits to take in good faith which it reasonably believes to be authorized or within the discretion or rights or powers conferred upon it by this Indenture. 

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of such counsel as to matters of law
shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in reliance thereon. 

  
 -63-








 (f) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs,
expenses and liabilities which might be incurred by it in compliance with such request or direction. 
 (g) The
Trustee may request that the Issuer deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate
may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 

(h) The Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under
this Indenture arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage;
epidemics; riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents; labor disputes; acts of civil or military authority and governmental action. 

(i) Anything in this Indenture notwithstanding, in no event shall the Trustee be liable for special, indirect, punitive
or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Issuer has been advised as to the likelihood of such loss or damage and regardless of the form of action. 

Section 7.03. Individual Rights of Trustee. 
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services for or otherwise deal with the Issuer, or any
Affiliates thereof, with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee, however, shall be subject to Sections 7.10 and 7.11 hereof. 

Section 7.04. Trustee’s Disclaimer. 
 The Trustee shall not be responsible for and makes no representation as to (i) the validity or adequacy of this Indenture or the Notes or (ii) whether a Default or Event of Default has occurred
and is continuing or will occur upon the execution and delivery of the Indenture or upon the issuance of the Notes. Trustee shall not be accountable for the Issuer’s use of the proceeds from the sale of Notes or any money paid to the Issuer
pursuant to the terms of this Indenture and it shall not be responsible for any statement of the Issuer in this Indenture or the Notes other than the Trustee’s certificate of authentication. 

Section 7.05. Notice of Defaults. 
 The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has received written notice of such Default or Event of Default at the Corporate
Trust Office of the Trustee. 
 Within 90 days after the occurrence of any Default or Event of Default hereunder, the Trustee
shall transmit by mail to Holders of Notes, as their names and addresses appear in the records of the Registrar, a notice of the Default or Event of Default known to the Trustee, unless such Default or Event of Default shall have been cured or
waived. Except in the case of an Event of Default in payment of principal of or interest on any Note, including an accelerated payment and the failure to make payment on the Change of Control Payment Date pursuant to a Change of Control Offer or on
the Offer Payment Date pursuant to a Net Proceeds Offer, the Trustee may withhold the notice if and so long as its Board of Directors, the executive committee of its Board of Directors or a committee of its directors and/or Trust Officers in good
faith determines that withholding the notice is in the interest of the Holders. This Section 7.05 shall be in lieu of the proviso to Section 315(b) of the TIA, and such proviso of Section 315(b) of the TIA is hereby expressly excluded
from this Indenture and the Notes, as permitted by the TIA. 

  
 -64-








 Section 7.06. Reports by Trustee to Holders. 

If required by TIA Section 313(a), within 60 days after May 15 of any year, commencing the first May 15 following the date
of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b), (c) and (d). 

Reports pursuant to this Section 7.06 shall be transmitted by mail: 

(a) to all registered Holders, as the names and addresses of such Holders appear on the Registrar’s books; and

 (b) to such Holders as have, within the two years preceding such transmission, filed their names and
addresses with the Trustee for that purpose. 
 A copy of each report at the time of its mailing to Holders shall be filed with
the Commission and each stock exchange, if any, on which the Notes are listed. The Issuer shall promptly notify the Trustee when the Notes are listed on any stock exchange or of any delisting thereof. 

Section 7.07. Compensation and Indemnity. 
 The Issuer shall pay to the Trustee from time to time such compensation as shall be agreed in writing between the Issuer and the Trustee for the Trustee’s services. The Trustee’s compensation
shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable fees and expenses, including out-of-pocket expenses incurred or made by it in connection with
the performance of its duties under this Indenture or in connection with the collection of any funds. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents and counsel. 

The Issuer shall indemnify each of the Trustee and its agents, employees, stockholders and directors and officers for, and hold them
harmless against, any loss, liability or expense incurred by them (including attorney’s fees and expenses) arising out of or in connection with the administration of this trust, including the reasonable costs and expenses of defending
themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or duties hereunder, except for such actions to the extent caused by any gross negligence, bad faith or willful misconduct on
their part as determined by a court of competent jurisdiction in a final order. The Trustee shall notify the Issuer promptly, in writing, of any claim asserted against the Trustee for which it may seek indemnity. At the Trustee’s sole
discretion, the Issuer shall defend the claim and the Trustee shall cooperate and may participate in the defense; provided that any settlement of a claim shall be approved in writing by the Trustee. The Issuer need not pay for any settlement
made without its written consent, which consent shall not be unreasonably withheld. The Issuer need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its gross negligence, bad faith or
willful misconduct as determined by a court of competent jurisdiction in a final order. 
 To secure the Issuer’s payment
obligations in this Section 7.07, the Trustee shall have a lien prior to the Notes on all assets or money held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of or interest on
particular Notes. 
 In addition and without prejudice to the rights provided to the Trustee under any provision of this
Indenture, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(f) or (g) hereof occurs, such expenses and the compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law. 
 The obligation of the Issuer under this Section 7.07 shall survive the
resignation or removal of the Trustee and the termination or satisfaction and discharge of this Indenture. 

“Trustee” for purposes of this Section shall include any predecessor Trustee and the Trustee in each of its capacities
hereunder and to each agent, custodian and other person employed to act hereunder; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee
hereunder.

 Section 7.08. Replacement of Trustee. 

The Trustee may resign at any time by so notifying the Issuer in writing. The Holders of a majority in principal amount of the
outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing and may appoint a successor Trustee. The Issuer may remove the Trustee at its election if: 

(a) the Trustee fails to comply with Section 7.10 hereof; 

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

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

(d) the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being
referred to herein as the retiring Trustee), the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Notes may appoint a successor Trustee
to replace the successor Trustee appointed by the Issuer. 
 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuer. Immediately after that, the retiring Trustee shall transfer, after payment of all sums then owing to the Trustee pursuant to Section 7.07 hereof, all property held by it as Trustee to the
successor Trustee, subject to the lien provided in Section 7.07 hereof, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each Holder. 
 If a successor Trustee does not take
office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in principal amount of the outstanding Notes may petition, at the expense of the Issuer, any court of competent
jurisdiction for the appointment of a successor Trustee. 
 If the Trustee, after written request by any Holder who has been a
bona fide holder of securities for any period of time specified under TIA Section 310(b), fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee. 
 Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the
Issuer’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 
 Section 7.09.
Successor Trustee by Consolidation, Merger or Conversion. 
 If the Trustee consolidates with, merges or converts into,
or transfers all or substantially all of its corporate trust business to, another corporation, subject to this Article 7, the successor corporation without any further act shall be the successor Trustee. 

Section 7.10. Eligibility; Disqualification. 
 This Indenture shall always have a Trustee which shall be eligible to act as Trustee under TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee shall have a combined capital and surplus of at
least $100,000,000 as set forth in its most recent published annual report of condition. If the Trustee has or shall acquire any “conflicting interest” within the meaning of TIA Section 310(b), the Trustee and the Issuer shall comply
with the provisions of TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or
participation in other securities of the Issuer are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this
Section 7.10, the Trustee shall resign immediately in the manner and with the effect hereinbefore specified in this Article 7. 

  
 -66-








 Section 7.11. Preferential Collection of Claims Against the Issuer. 

The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee
who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. The provisions of TIA Section 311 shall apply to the Issuer and the Guarantors as obligors upon the Notes. 

ARTICLE 8 

AMENDMENTS, SUPPLEMENTS AND WAIVERS 
 Section 8.01. Without Consent of Holders. 
 (a) The Issuer and the
Guarantors, when authorized by a Board Resolution, and the Trustee may amend or supplement this Indenture, the Notes or the Note Guarantees without notice to or consent of any Holder: 

(1) to cure any ambiguity, defect, omission, mistake 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 Issuer’s or a Guarantor’s obligations to the Holders in the case of a
merger, consolidation or sale of all or substantially all of the Issuer’s or such Guarantor’s assets in accordance with Article 5; 
 (4) to add any Note Guarantee or to effect the release of any Guarantor from any of its obligations under its Note Guarantee or this Indenture (to the extent permitted by this Indenture); 

(5) to make any change that would provide any additional rights or benefits to the Holders or that does not materially
adversely affect the rights of any Holder; 
 (6) to effect or maintain the qualification of this Indenture
under the Trust Indenture Act; 
 (7) to secure the Notes or any Note Guarantees or any other obligation under
this Indenture; 
 (8) to evidence and provide for the acceptance of appointment by a successor trustee;

 (9) to conform the text of this Indenture or the Notes to any provision of the Description of the Unsecured
Notes section of the Offering Memorandum to the extent that such provision in the Description of the Unsecured Notes was intended to be a verbatim recitation of a provision of this Indenture, the Note Guarantees or the Notes; or 

(10) to provide for the issuance of Additional Notes in accordance with this Indenture; 

Section 8.02. With Consent of Holders. 
 (a) Subject to Section 6.07 hereof, the Issuer and the Guarantors, when each is authorized by a Board Resolution of their respective Boards of Directors, and the Trustee may amend or supplement this
Indenture, the Notes or the Note Guarantees with the consent (which may include consents obtained in connection with a tender offer or exchange offer for the Notes) of the Holders of at least a majority in principal amount of the Notes then
outstanding. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in principal amount of the Notes then outstanding may waive any existing Defaults under, or compliance by the Issuer or any Guarantor with any provision of, this
Indenture, the Notes, or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04 hereof, may not: 

  
 -67-








 (1) reduce, or change the maturity of, the principal of any Note;

 (2) reduce the rate of or extend the time for payment of interest on any Note; 

(3) reduce any premium payable upon redemption of the Notes, change the date on which any Notes are subject to redemption
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 Notes (including pursuant to
Section 4.12 and Section 4.15) shall not be deemed a redemption of the Notes; 
 (4) make any Note
payable in money or currency other than that stated in the Notes; 
 (5) modify or change any provision of this
Indenture or the related definitions to affect the ranking of the Notes or any Note Guarantee in a manner that adversely affects the Holders; 
 (6) reduce the percentage of Holders necessary to consent to an amendment or waiver to this Indenture or the Notes; 

(7) waive a default in the payment of principal of or interest on any Notes (except a rescission of acceleration of the
Notes by the Holders thereof as provided in this Indenture and a waiver of the payment default that resulted from such acceleration); 
 (8) impair the rights of Holders to receive payments of principal of or interest on the Notes on or after the due date therefor or to institute suit for the enforcement of any payment on the Notes;

 (9) release any Guarantor that is a Significant Subsidiary from any of its obligations under its Note
Guarantee or this Indenture, except as permitted by this Indenture; or 
 (10) make any change in these
amendment, supplement and waiver provisions. 
 The consent of the Holders of the Notes is not necessary under this Indenture to
approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. 

After an amendment or supplement under this Section 8.02 becomes effective, the Issuer shall mail to Holders of the Notes a
notice briefly describing such amendment or supplement. However, the failure to give such notice to all Holders of the Notes, or any defect therein, will not impair or affect the validity of the amendment or supplement. 

Section 8.03. Compliance with TIA. 
 Every amendment to or supplement of this Indenture, the Notes or the Note Guarantees shall comply with the TIA as then in effect. 
 Section 8.04. Revocation and Effect of Consents. 
 Until an amendment,
waiver or supplement 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. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note or portion of such Note by notice to the Trustee or the Issuer received before the
date on which the Trustee receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. 

  
 -68-








 The Issuer may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or
their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90
days after such record date. 
 After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless
it makes a change described in any of clauses (1) through (10) of Section 8.02 hereof, in which case, the amendment, supplement or waiver shall bind only each Holder who has consented to it and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder’s Note. 
 Section 8.05. Notation on or Exchange of
Notes. 
 If an amendment, supplement, or waiver changes the terms of a Note, the Trustee may request the Holder to deliver
it to the Trustee. In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, in exchange for the Note the Issuer shall
issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement, or waiver. 

Section 8.06. Trustee To Sign Amendments, etc. 
 The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this
Article 8 is authorized or permitted by this Indenture and that such amendment, supplement or waiver constitutes the legal, valid and binding obligation of the Issuer and any Guarantors, enforceable in accordance with its terms (subject to customary
exceptions). The Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

ARTICLE 9 

DISCHARGE OF INDENTURE; DEFEASANCE 
 Section 9.01. Satisfaction and Discharge of Indenture. 
 (a) This
Indenture shall be discharged and shall cease to be of further effect (except those obligations referred to in Section 9.01(c)) as to all outstanding Notes and the Trustee, on written demand of and at the expense of the Issuer, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture, when: 
 (1) Either (A) all
the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter
repaid to the Issuer or discharged from this trust) have been delivered to the Trustee for cancellation, or 

(B) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable,
(ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption pursuant to paragraph 5 of the Notes and, in any case, the Issuer has irrevocably deposited or caused to be
deposited with the Trustee as trust funds, in trust solely for the benefit of the Holders, U.S. legal tender, U.S. Government Obligations 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 (including all principal and accrued interest) on the Notes not theretofore delivered to the Trustee for cancellation; 

  
 -69-








 (2) the Issuer has paid all other sums payable by it under this Indenture;
and 
 (3) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward
the payment of the Notes at maturity or on the date of redemption, as the case may be. 
 (b) In addition, the Issuer must
deliver an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent to satisfaction and discharge have been complied with. 
 (c) Notwithstanding Section 9.01(a), the Issuer’s obligations in Article 2 and Sections 4.07, 7.07, 9.06 and 9.07 hereof shall survive until the Notes are no longer outstanding pursuant to the
last paragraph of Section 2.08 hereof. After the Notes are no longer outstanding, the Issuer’s obligations in Sections 7.07, 9.06 and 9.07 hereof shall survive. 
 (d) After such delivery or irrevocable deposit, the Trustee upon request shall acknowledge in writing the discharge of the Issuer’s and each Guarantor’s obligations under the Notes, the Note
Guarantees and this Indenture except for those surviving obligations specified above. 
 (e) The Issuer shall provide notice of
discharge or defeasance pursuant to this Article 9 within ten (10) days after deposit of funds or U.S. Government Obligations. If payment at stated maturity of less than all of the Notes of any series is to be provided for in the manner and
with the effect provided in this Section 9.01, the Trustee shall select such Notes, or portions or principal amount thereof, in the manner specified by Section 3.02 for selection for redemption of less than all the Notes of a series.

 Section 9.02. Legal Defeasance. 
 (a) The Issuer may, at its option at any time, elect to have this Section be applied to all outstanding Notes upon compliance with the conditions set forth in Section 9.04. 

(b) Upon the Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b), the Issuer and each
Guarantor shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from their respective obligations with respect to all outstanding Notes and the Note Guarantees on the date the
conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and each Guarantor shall be deemed to have paid and discharged the entire obligations represented
by the Notes and the Note Guarantees, and this Indenture shall cease to be of further effect as to all outstanding Notes and the Note Guarantees, except as to: (i) the rights of Holders of outstanding Notes to receive solely from the trust fund
described in Section 9.05 hereof, and as more fully set forth in such Section, payments in respect of the principal of and interest on such Notes when such payments are due from such trust fund, (ii) the Issuer’s obligations with
respect to the Notes under Article 2 and Section 4.07 hereof, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s obligations in connection therewith and (iv) this Article 9. Subject

(b) Upon the Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b), the Issuer and each
Guarantor shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from their respective obligations under the covenants contained in Sections 4.02, 4.05 and 4.08 through 4.21 hereof, inclusive, and
subclause (3) of Section 5.01(a) hereof with respect to the outstanding Notes and the Note Guarantees on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant


  
 -70-








 
Defeasance”); provided, however, that Covenant Defeasance will not be effective until such time as Events of Default contained in Section 6.01(g) and
(h) no longer apply, and the Notes and the Note Guarantees shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes and the Note Guarantees, the
Issuer and each Guarantor may omit to comply with and shall 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 shall not constitute a Default or an Event or Default under Section 6.01(d) hereof, but, except as
specified above, the remainder of this Indenture, and such Notes and the Note Guarantees shall be unaffected thereby. In addition, upon the Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b),
subject to the satisfaction of the conditions set forth in Section 9.04 hereof, the Events of Default described under clauses (c) through (f), (i) and (j) of Section 6.01 and the Events of Default described under clauses
(g) and (h) of Section 6.01 (but only with respect to Significant Subsidiaries of the Issuer), in each case, will no longer constitute an Event of Default. 
 Section 9.04. Conditions to Legal Defeasance or Covenant Defeasance. 

The following shall be the conditions to the application of either Section 9.02 or 9.03 hereof to the outstanding Notes and the Note
Guarantees: 
 (1) the Issuer must irrevocably deposit with the Trustee (or other qualifying trustee), as trust
funds, in trust solely for the benefit of the Holders, U.S. legal tender or U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest), in the opinion of a
nationally recognized investment bank, appraisal firm or firms of independent public accountants selected by the Issuer, to pay the principal of and interest on the Notes on the stated date for payment thereof or on the applicable Redemption Date,
as the case may be; 
 (2) in the case of an election under Section 9.02 hereof, the Issuer shall have
delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this
Indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for U.S. federal
income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(3) in the case of an election under Section 9.03 hereof, the Issuer shall have delivered to the Trustee an Opinion
of Counsel confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default shall
have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing); 

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of or constitute a default
under this Indenture or any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound (other than any such Default or default resulting solely from the
borrowing of funds to be applied to such deposit and the grant of any Lien to secure such borrowings); 
 (6)
the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders over any other creditors of the Issuer or with the intent of defeating,
hindering, delaying or defrauding any other creditors of the Issuer or others; and 

  
 -71-








 (7) the Issuer shall have delivered to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that the conditions precedent provided for in, in the case of the Officers’ Certificate, clauses (1) through (6) and, in the case of the Opinion of Counsel, clauses (2) and/or
(3) and (5) of this Section 9.04 have been complied with. 
 If the funds deposited with the Trustee to effect
Covenant Defeasance are insufficient to pay the principal of and interest on the Notes when due, then the Issuer’s obligations and the obligations of Guarantors under this Indenture will be revived and no such defeasance will be deemed to have
occurred. 
 Section 9.05. Application of Trust Money. 
 All money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 9.01 or 9.04 hereof in respect of the outstanding Notes shall be held in
trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any 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 and accrued interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Issuer and the Guarantors shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to
Section 9.01 or 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. 

Anything in this Article 9 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon a
written request of the Issuer in the form of an Officers’ Certificate any money or U.S. Government Obligations held by it as provided in Section 9.01 or 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, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent satisfaction and discharge of this Indenture, Legal
Defeasance or Covenant Defeasance, as the case may be. 
 Section 9.06. Repayment to the Issuer. 

Subject to Section 9.05 hereof, the Trustee and the Paying Agent shall promptly pay to the Issuer upon request any excess U.S. legal
tender or U.S. Government Obligations held by them at any time and thereupon shall be relieved from all liability with respect to such money. Subject to applicable abandoned property laws, the Trustee and the Paying Agent shall pay to the Issuer
upon request any money held by them for the payment of principal or interest that remains unclaimed for two years; provided that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Issuer
cause to be published once in a newspaper of general circulation in The City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed, and that after a date specified therein which shall be at least 30 days
from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders entitled to such money must look to the Issuer for payment as general creditors
unless an applicable law designates another Person. 
 Section 9.07. Reinstatement. 

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 9.01, 9.02 or
9.03 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and each Guarantor’s obligations
under this Indenture, the Notes and the Note Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article 9 until such time as the Trustee or Paying Agent is permitted to apply all such U.S. legal tender or
U.S. Government Obligations in accordance with Section 

  
 -72-








 
9.01 hereof; provided, however, that if the Issuer or the Guarantors have made any payment of principal of or accrued interest on any Notes because of the reinstatement of their
obligations, the Issuer and each such Guarantor shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. 

ARTICLE 10 

GUARANTEES 
 Section 10.01.
Unconditional Guarantee. 
 Each Guarantor hereby unconditionally, jointly and severally, guarantees to each Holder of a
Note authenticated by the Trustee and to the Trustee and its successors and assigns that the principal of and interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at the Maturity Date, by
acceleration or otherwise, and interest on the overdue principal and interest on any overdue interest on the Notes, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or under the Notes will be promptly paid
in full or performed, all in accordance with the terms hereof and thereof; subject, however, to the limitations set forth in Section 10.03 hereof. Each Guarantor hereby agrees that to the maximum extent permitted under applicable law, its
obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any
provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. To the maximum extent
permitted under applicable law, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer,
protest, notice and all demands whatsoever and covenants that the Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. If any Holder or the Trustee is required by any
court or otherwise to return to the Issuer, any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by the Issuer or any Guarantor to the Trustee or such
Holder, each Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, to the maximum extent permitted under applicable law, as between a Guarantor, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purpose of each Note Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) shall
become due and payable by each Guarantor for the purpose of each Note Guarantee. 
 Each Guarantor also agrees to pay any and
all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Article 10. 
 Section 10.02. Severability. 
 In case any provision of this Article
10 shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 Section 10.03. Limitation on Guarantor’s Liability. 
 (a) To the
extent applicable, a Guarantor’s liability in respect of its Note Guarantee shall be limited to the extent set forth below: 
 (1) Limitations Applicable to U.S. Guarantors. Each Guarantor that is incorporated, organized or formed, as the case may be, under the laws of the United States, any State thereof or the District
of Columbia (a “U.S. Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm that it is the intention of all such parties that the Note Guarantee of a U.S. Guarantor does not constitute a fraudulent
transfer or conveyance for purposes of Title 11 of the United States Code, as amended, 

  
 -73-








 
the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar U.S. Federal or state or other applicable law. To effectuate the foregoing intention, each Holder, by its
acceptance of a Note, and each U.S. Guarantor hereby irrevocably agree that the obligations of a U.S. Guarantor under its Note Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed
liabilities of such U.S. Guarantor (including, without limitation, any guarantees under any Credit Facility) and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of
such other Guarantor under its Note Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such U.S. Guarantor not constituting such a fraudulent transfer or conveyance. 

(2) Limitations Applicable to Other Guarantors. Each Guarantor that is incorporated, organized or formed, as the
case may be, under the laws of any jurisdiction other than one set forth in clause (1) above (an “Other Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm that it is the intention of all such
parties that the Note Guarantee of an Other Guarantor does not constitute a fraudulent transfer or conveyance for purposes of applicable law. To effectuate the foregoing intention, each Holder, by its acceptance of a Note, and each Other Guarantor
hereby irrevocably agree that the obligations of an Other Guarantor under its Note Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Other Guarantor (including,
without limitation, any guarantees under any Credit Facility) and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee or
pursuant to its contribution obligations under this Indenture, result in the obligations of such Other Guarantor not constituting such a fraudulent transfer or conveyance. 
 (b) If following the date of this Indenture and notwithstanding anything in Section 8.02 to the contrary: 
 (1) (i) there shall be any change in the laws of the United States, any State thereof or the District of Columbia or (ii) any Restricted Subsidiary incorporated, organized or formed, as the case may
be, under the laws of any jurisdiction other than the United States, any State thereof or the District of Columbia (a “Future Guarantor”) shall be required to guarantee the Notes pursuant to Section 4.20 hereof and the Issuer
shall reasonably determine that clause (2) with respect to Other Guarantors shall not adequately address the limitations on the Note Guarantee of such Future Guarantor imposed by applicable law of the jurisdiction of incorporation, organization
or formation, as the case may be, of any such Future Guarantor; or 
 (2) the Issuer shall reasonably determine
that it shall be necessary or advisable to amend the terms of subsection (a) of this Section 10.03 or to add additional provisions related to the limitations imposed on the Note Guarantee of a Future Guarantor, 

then upon the delivery of an Officers’ Certificate and Opinion of Counsel reasonably satisfactory to the Trustee, the Issuer shall be entitled to
amend such clauses or add such additional provisions (including any related modifications to the form of Note Guarantee attached hereto in Exhibit A), as the case may be, in order for the Note Guarantee of a Guarantor not to so violate
applicable law. 
 (c) Each Guarantor that makes a payment for distribution under its Note Guarantee shall be entitled to a
contribution from each other Guarantor in a pro rata amount based on adjusted net assets of each Guarantor. 
 Section 10.04.
Successors and Assigns. 
 This Article 10 shall be binding upon each Guarantor and its successors and assigns and shall
ensure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in
the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 

  
 -74-








 Section 10.05. No Waiver. 

Each of the Guarantors agrees that to the maximum extent permitted under applicable law, (a) neither a failure nor a delay on the
part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power
or privilege and (b) the rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in
equity, by statute or otherwise. 
 Section 10.06. Release of Guarantor. 

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

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

(2) if such Guarantor is designated as an Unrestricted Subsidiary or otherwise ceases to be a Restricted Subsidiary, in
each case in accordance with the provisions of this Indenture, upon effectiveness of such designation or when it first ceases to be a Restricted Subsidiary; 
 (3) if such Guarantor is released from or otherwise ceases to guarantee any Credit Facility of the Issuer or any other Guarantor; 

(4) in the event of the defeasance or discharge of this Indenture as described under Sections 9.01, 9.02 and 9.03; or

 (5) dissolution of such Guarantor, provided no Default or Event of Default has occurred that is
continuing. 
 Upon delivery by the Issuer to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the
effect that one of the foregoing requirements has been satisfied and the conditions to the release of a Guarantor from its Note Guarantee under this Section 10.06 have been met, the Trustee shall execute any documents reasonably required in
order to evidence the release of such Guarantor from its obligations under its Note Guarantee. 
 Section 10.07. Execution of
Supplemental Indenture for Future Guarantors. 
 Each Subsidiary which is required to become a Guarantor shall, and the
Issuer shall cause each such Subsidiary to, promptly execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit E hereto pursuant to which such Subsidiary shall become a Guarantor under this Article
10 and shall guarantee the obligations of the Issuer under the Notes and this Indenture. Concurrently with the execution and delivery of such supplemental indenture, the Issuer shall deliver to the Trustee an Opinion of Counsel to the effect that
such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to
creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, each of such supplemental indenture and the Note Guarantee of such Guarantor is a legal, valid and binding obligation of such
Guarantor, enforceable against such Guarantor in accordance with its terms. 
 Section 10.08. Notation of Note Guarantee.

 To evidence the Note Guarantee set forth in this Article 10, each Guarantor hereby agrees that a notation of such Note
Guarantee shall be placed on each Note authenticated and made available for delivery by the Trustee and that this Note Guarantee shall be executed on behalf of each Guarantor by the manual or facsimile signature of an Officer of each Guarantor. Each
Guarantor hereby agrees that the Note Guarantee set forth in Section 10.01 hereof 

  
 -75-








 
shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. If an Officer of a Guarantor whose signature is on the Note Guarantee
no longer holds that office at the time the Trustee authenticates the Note on which the Note Guarantee is endorsed, the Note Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder,
shall constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of each Guarantor. 
 Section 10.09.
Subordination of Subrogation and Other Rights. 
 Each Guarantor hereby agrees that any claim against the Issuer that
arises from the payment, performance or enforcement of such Guarantor’s obligations under the Note Guarantee or this Indenture, including, without limitation, any right of subrogation, shall be subject and subordinate to, and no payment with
respect to any such claim of such Guarantor shall be made before, the payment in full in cash of all outstanding Notes in accordance with the provisions provided therefor in this Indenture.

 (REVERSE OF SECURITY) 

10.250% SENIOR NOTE DUE 2019 
 1. Interest. Hercules Offshore, Inc., a Delaware corporation (the “Issuer”), promises to pay interest on the principal amount of this Note at the rate per annum shown above.
Interest on the Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from April 3, 2012. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, commencing
October 1, 2012. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 The Issuer shall pay
interest on overdue principal and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful from time to time on demand at the rate then borne by the Notes. 

2. Method of Payment. The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are the registered
Holders at the close of business on the March 15 or September 15 immediately preceding the Interest Payment Date (whether or not such day is a Business Day) even if the Notes are cancelled on registration of transfer or registration of
exchange after such Record Date. Holders must surrender Notes to a Paying Agent to collect payments of principal. Payments of principal and interest will be made in money of the United States that at the time of payment is legal tender for payment
of public and private debts. If a Holder of Notes in certificated form has given wire transfer instructions to the Issuer at least ten Business Days prior to the applicable payment date, the Issuer will make all payments on such Holder’s Notes
by wire transfer of immediately available funds to the account specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Paying Agent unless the Issuer elects to make interest payments by check
mailed to the Holders at their addresses set forth in the register of Holders. 
 3. Paying Agent and Registrar.
Initially, U.S. Bank National Association, a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Issuer may change any Paying Agent, Registrar or co-Registrar without notice to the Holders.
Neither the Issuer nor any of its Affiliates may act as Paying Agent but may act as Registrar or co-Registrar. The Issuer has designated the Corporate Trust Office of the Trustee as its office where Notes may be surrendered for registration of
transfer or exchange or for presentation for payment and where notices and demands to or upon the Issuer in respect of the Notes may be served. 
 4. Indenture. The Issuer issued this Note under an Indenture, dated as of April 3, 2012 (the “Indenture”), by and among the Issuer, the Guarantors and the Trustee. This Note
is one of a duly authorized issue of Initial Notes of the Issuer designated as its 10.250% Senior Notes due 2019 (the “Notes”). The Notes include the Initial Notes and the Additional Notes, if any, issued pursuant to the Indenture.
The Initial Notes and the Additional Notes are treated as a single class of securities under the Indenture. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary
herein, the Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of them. The Notes are general unsecured obligations of the Issuer. 

5. Redemption. 
 (a) Optional Redemption. The Notes will be redeemable, at the Issuer’s option, in whole at any time or in part from time to time, on and after April 1, 2015 at the following Redemption
Prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on April 1 of the applicable year set forth below, plus, in each case, accrued and unpaid interest to the Redemption Date
(subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date):

 (b) Redemption at Applicable Premium. In addition, prior to April 1, 2015, the Issuer may
redeem the Notes, at its option, in whole at any time or in part from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus the Applicable Premium as of, and accrued and unpaid interest to the
applicable Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date). 
 (c) Redemption upon Consummation of Certain Qualified Equity Offerings. Notwithstanding the foregoing, at any time, or from time to time, prior to April 1, 2015, the Issuer may on any one or
more occasions, at its option, use all or any portion of the net cash proceeds of one or more Qualified Equity Offerings to redeem Notes at a Redemption Price equal to 110.250% of the principal amount of the Notes to be redeemed plus accrued and
unpaid interest 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); provided that at least 65.0% of the aggregate principal amount of
Notes originally issued on the Issue Date remains outstanding immediately after giving effect to any such redemption. In order to effect the foregoing redemption with the proceeds of any Qualified Equity Offering, the Issuer shall consummate such
redemption not more than 180 days after the consummation of any such Qualified Equity Offering. 
 6. Notice of
Redemption. Notice of redemption under paragraph 5 of this Note will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder to be redeemed at such Holder’s 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 satisfaction and discharge of the Indenture. 
 Except as set forth in the Indenture, if money for the redemption of the Notes called for redemption shall have been deposited with the Paying Agent for redemption on such redemption date, then, unless
the Issuer defaults in the payment of such Redemption Price plus accrued interest, if any, the Notes called for redemption will cease to bear interest from and after such Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued interest, if any. 
 7. Offers to Purchase. The Indenture provides
that, in certain circumstances following an Asset Sale (as defined in the Indenture) and upon the occurrence of a Change of Control (as defined in the Indenture), and subject to further limitations contained therein, the Issuer will make an offer to
purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 
 8. Denominations;
Transfer; Exchange. The Notes are in registered form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder shall register the transfer or exchange of Notes in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The
Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption. 
 9.
Persons Deemed Owners. The registered holder of a Note shall be treated as the owner of it for all purposes. 
 10.
Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Issuer. After that, Holders entitled to money must look to the Issuer for
payment as general creditors unless an “abandoned property” law designates another Person. 

  
 A-5








 11. Legal Defeasance and Covenant Defeasance. If the Issuer at any time deposits with
the Trustee U.S. legal tender or U.S. Government Obligations sufficient to pay the principal of and interest on the Notes to redemption or the scheduled due dates and complies with the other provisions of the Indenture relating to Covenant
Defeasance, the Issuer will be discharged from certain provisions of the Indenture and the Notes (including certain covenants, but excluding its obligation to pay the principal of and interest on the Notes). The Notes are also subject to Legal
Defeasance as provided in Article 9 of the Indenture. 
 12. Amendments, Supplements, and Waivers. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and any existing Default or Event of Default or noncompliance
with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture or the
Notes to, among other things, cure any ambiguity, defect, omission, mistake or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes or make any other change that does not adversely affect in any material
respect the rights of any Holder. 
 13. Restrictive Covenants. The Indenture imposes certain limitations on the ability
of each of the Issuer and its Restricted Subsidiaries to, among other things, incur additional Indebtedness, make payments in respect of its Equity Interests, enter into transactions with Affiliates, create dividend or other payment restrictions
affecting Restricted Subsidiaries, sell assets, create Liens, make certain Investments, merge or consolidate with any other Person, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of its assets. Such limitations are
subject to a number of important qualifications and exceptions. The Issuer must annually report to the Trustee on compliance with such limitations. 
 14. Successor Entity. When a successor entity assumes, in accordance with the Indenture, all the obligations of its predecessor under the Notes and the Indenture, and immediately before and
thereafter no Default or Event of Default exists and certain other conditions are satisfied, the predecessor entity will be released from those obligations. 
 15. Defaults and Remedies. Events of Default are set forth in the Indenture. If an Event of Default (other than an Event of Default specified in Section 6.01(g) or (h)) shall occur and be
continuing, the Trustee, by written notice to the Issuer, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare (an “acceleration
declaration”) all amounts owing under the Notes to be due and payable upon the earlier of (x) the final maturity (after giving effect to any applicable grace period or extensions thereof) or an acceleration of any Indebtedness under
any Credit Facility prior to the express final stated maturity thereof and (y) five Business Days after the collateral agent under each Credit Facility receives the acceleration declaration, but, only if such Event of Default is then
continuing. No such rescission shall affect any subsequent Default or impair any right consequent thereto. If an Event of Default specified in Section 6.01(g) or (h) occurs with respect to the Issuer and is continuing, then, to the extent
permitted by applicable law, all unpaid principal of and accrued and unpaid interest on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or
any Holder. 
 16. Trustee Dealings with the Issuer. The Trustee under the Indenture, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the Issuer, and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee. 

17. No Recourse Against Others. As more fully described in the Indenture, no director, officer, employee, stockholder or
incorporator of the Issuer shall have any liability for any obligations of the Issuer under the Notes or this Indenture, or of any Guarantor under its 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. Such waiver and release are part of the consideration for the issuance of the Notes.

we and any person acting on our behalf reasonably believed that the transferee was outside the United States, or (b) the transaction was executed in, on or through the facilities of a designated off-shore securities market and neither we nor
any person acting on our behalf knows that the transaction has been prearranged with a buyer in the United States; 
 (3) no directed selling efforts have been made in the United States in contravention of the requirements of Rule 903(a) or Rule 904(a) of Regulation S, as applicable; 

(4) the transaction is not part of a plan or scheme to evade the registration requirements of the Securities Act; and

 (5) we have advised the transferee of the transfer restrictions applicable to the Notes. 

You and Hercules Offshore, Inc. are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a copy
hereof to any interested party in any administrative or legal proceedings or official inquiry with respect to the matters covered hereby. Defined terms used herein without definition have the respective meanings provided in Regulation S.
