 (h) Cancellation and/or
Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such
Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who
will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such
Global Note, by the Trustee or by the Depositary at the direction of the Trustee, to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial
interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note, by the Trustee or by the Depositary at the direction of the Trustee, to reflect such increase. 

(i) General Provisions Relating to Transfers and Exchanges. 

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate
Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 
 (ii) No service charge shall be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10,
3.06, 4.10, 4.15 and 9.05 hereof). 
 (iii) The Registrar shall not be required to register the transfer of or
exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 

  
 43 








 (iv) All Global Notes and Definitive Notes issued upon any registration of
transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such
registration of transfer or exchange. 
 (v) Neither the Registrar nor the Company will be required: 

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15
days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note selected for redemption in whole or
in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date. 

(vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may
deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal, premium or interest on such Notes and for all other purposes, and none of the Trustee, any Agent or
the Company shall be affected by notice to the contrary. 
 (vii) The Trustee shall authenticate Global Notes and
Definitive Notes in accordance with the provisions of Section 2.02 hereof. 
 (viii) All certifications,
certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 

SECTION 2.07. Replacement Notes. If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If
required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that
any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 
 Every replacement
Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 

  
 44 








 SECTION 2.08. Outstanding Notes. The Notes outstanding at any time are all the Notes
authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this
Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to
it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under
Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than
the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall
cease to accrue interest. 
 SECTION 2.09. Treasury Notes. In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as
though 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 that a Responsible Officer of the Trustee actually knows are so owned shall be
so disregarded. 
 SECTION 2.10. Temporary Notes. Until certificates representing Notes are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate
for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Notes. 

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. 

SECTION 2.11. Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying
Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall destroy cancelled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all cancelled Notes will be delivered to the Company. The Company may not issue new Notes to
replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 

  
 45 








 SECTION 2.12. Defaulted Interest. If the Company defaults in a payment of interest on
the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the
Notes and in Section 4.01 hereof. The Company shall promptly notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed
each such special record date and payment date, provided that no such special record date shall be less than two Business Days prior to the related payment date for such defaulted interest. At least five Business Days before the special
record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and
the amount of such interest to be paid. 
 SECTION 2.13. CUSIP Numbers. The Company in issuing the Notes (including
Additional Notes) may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such
redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers. 
 ARTICLE 3 
 Redemption and Prepayment Section 

SECTION 3.01. Notices to Trustee. If the Company elects to redeem Notes pursuant to the optional redemption provisions of
Section 3.07 hereof, it shall furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers’ Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall
occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price. 
 SECTION 3.02. Selection of Notes to be Redeemed. If less than all of the Notes are to be redeemed at any time, selection of Notes for redemption shall be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate; provided that
no Notes of $2,000 or less shall be redeemed in part. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the
redemption date by the Trustee from the outstanding Notes not previously called for redemption. 

  
 46 








 The Trustee shall promptly notify the Company in writing of the Notes selected for
redemption and, in the case of any Note selected for partial redemption, the portion of the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $2,000 or integral multiples of $1,000. Except as
provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 
 SECTION 3.03. Notice of Redemption. Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be
mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address. 

The notice shall identify the Notes (including CUSIP numbers) to be redeemed and shall state: 

(a) the redemption date; 
 (b) the redemption price; 
 (c) if less than all of the Notes are
to be redeemed, the identification of the particular Notes to be redeemed; 
 (d) if any Note is being redeemed
in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued in the name of the
Holder upon cancellation of the original Note; 
 (e) the name and address of the Paying Agent; 

(f) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(g) that on the redemption date and, if applicable, upon the satisfaction of any conditions to such redemption set forth
in such notice of redemption, the redemption price will become due and payable upon each such Note or portion thereof, and that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue
on and after the redemption date; 
 (h) the paragraph of the Notes and/or Section of this Indenture pursuant to
which the Notes called for redemption are being redeemed; and 
 (i) that no representation is made as to the
correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 

  
 47 








 In addition, if such redemption is subject to satisfaction of one or more conditions
precedent, such notice of redemption shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or
such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date as stated in such notice, or by the Redemption Date as so delayed. 

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense;
provided, however, that the Company shall have delivered to the Trustee, at least 35 days prior to the redemption date (unless a shorter period is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee
give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is given in accordance with Section 3.03 hereof,
Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, subject to the satisfaction of any conditions precedent provided in such notice. 

SECTION 3.05. Deposit of Redemption Price. No later than 11:00 a.m. New York City Time on the redemption date, the Company shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited
with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. 
 If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a
Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such
record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date
until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 

SECTION 3.06. Notes Redeemed in Part. Upon surrender and cancellation of a Note that is redeemed in part, the Company shall issue
and, upon the Company’s written request, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered and cancelled. 

  
 48 








 SECTION 3.07. Optional Redemption. (a) Except as set forth in clause (b), (c) or
(d) of this Section 3.07, the Notes shall not be redeemable at the Company’s option prior to March 15, 2017. Thereafter, the Notes will be subject to redemption at any time at the option of the Company, in whole or in part on one
or more occasions, upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on March 15 of the years indicated below:

 (b) Notwithstanding the foregoing, at any time prior to March 15, 2017, the Company may also redeem
all or a part of the Notes on one or more occasions, upon not less than 30 nor more than 60 days’ prior notice at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and
unpaid interest to, the date of redemption (the “Redemption Date”). 
 (c) In addition, at any time prior to
March 15, 2015, the Company may on any one or more occasions redeem up to an aggregate of 35% of the principal amount of Notes (including any Additional Notes) outstanding at a redemption price of 106.375% of the principal amount thereof, plus
accrued and unpaid interest, if any, thereon, to the redemption date, with the net cash proceeds of any one or more Equity Offerings; provided that at least 65% of the aggregate principal amount of Notes outstanding on the Issue Date remain
outstanding immediately after each occurrence of such redemption; and provided, further, that each such redemption shall occur within 120 days of the date of the closing of such Equity Offering.

subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date. 
 (f) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. 

SECTION 3.08. Mandatory Redemption. Except as set forth under Sections 3.09, 4.10 and 4.15 hereof, the Company shall not be
required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 SECTION 3.09. Offer to Purchase
by Application of Excess Proceeds. In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence an Asset Sale Offer (as defined in Section 4.10 hereof), it shall follow the procedures specified below.


  
 49 








 The Asset Sale Offer shall remain open for a period of 20 Business Days following its
commencement and no longer, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase
Date”), the Company shall purchase the principal amount of Notes required to be purchased pursuant to Section 4.10 hereof (the “Offer Amount”) or, if less than the Offer Amount has been tendered, all Notes tendered in
response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. 
 If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon the commencement of an Asset Sale Offer, the Company shall give notice to the Trustee and each of the Holders. The notice shall contain all instructions and materials necessary to enable such Holders
to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state: 

(a) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length
of time the Asset Sale Offer shall remain open; 
 (b) the Offer Amount, the purchase price and the Purchase
Date; 
 (c) that any Note not tendered or accepted for payment shall continue to accrete or accrue interest;

 (d) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the
Asset Sale Offer shall cease to accrete or accrue interest after the Purchase Date; 
 (e) that Holders electing
to have a Note purchased pursuant to an Asset Sale Offer may only elect to have all of such Note purchased and may not elect to have only a portion of such Note purchased; 

(f) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the
Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address
specified in the notice at least three days before the Purchase Date; 

  
 50 








 (g) that Holders shall be entitled to withdraw their election if the
Company, the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note
the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 
 (h) that, if the aggregate principal amount of Notes surrendered by Holders thereof exceeds the Offer Amount, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments
as may be deemed appropriate by the Company so that only Notes in denominations of $2,000 or integral multiples of $1,000, shall be purchased); and 
 (i) that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

 On or before the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to, the
extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered. The Company, the depositary or the Paying Agent, as the case may be,
shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the
Company shall promptly issue a new Note, and the Trustee, upon written request from the Company shall authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer on the Purchase Date.

 ARTICLE 4 
 Covenants 
 SECTION 4.01. Payment of Notes. The Company shall pay or
cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than
the Company or a Subsidiary thereof, holds as of 11:00 a.m. New York City Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then
due. The Company shall pay interest (including post-petition interest in any proceeding under the Bankruptcy Code) on overdue principal at the rate borne on the Notes to the extent lawful; it shall pay interest (including post-petition interest in
any proceeding under the Bankruptcy Code) on overdue installments of interest at the same rate to the extent lawful. The Company shall notify the Trustee in writing if Additional Interest is owed under the Registration Rights Agreement.

 SECTION 4.02. Maintenance of Office or Agency. The Company shall maintain in the
Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an Affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where
notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations surrenders, notices and demands may be made or served at the Corporate Trust Office of the
Trustee. 
 The Company may also from time to time designate one or more other offices or agencies where the Notes may be
presented or surrendered for any or all such purpose and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or
agency. 
 The Company hereby designates the Corporate Trust Services office of U.S. Bank Trust National Association, an
Affiliate of the Trustee, located at the date hereof at 100 Wall Street, Suite 1600, New York, New York, 10005, as one such office or agency of the Company in accordance with Section 2.03 hereof. 

SECTION 4.03. Reports. (a) Whether or not required by the rules and regulations of the Commission, so long as any Notes are
outstanding, the Company shall furnish to each of the Holders of Notes within the time periods specified in the Commission’s rules and regulations all quarterly and annual financial information that would be required to be contained in a filing
with the Commission on Forms 10-Q and 10-K if the Company were required to file such financial information, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the
annual information only, reports thereon by the Company’s independent public accountants (which shall be firm(s) of established national reputation). In addition, whether or not required by the rules and regulations of the Commission, the
Company shall file a copy of all such information and reports with the Commission (unless such filing is not permitted) for public availability and make such information available to securities analysts and prospective investors upon request, in
each case at the time specified for the filings of such reports by the Commission. 
 (b) The Company shall be deemed to have
furnished such reports to the Trustee and Holders of the Notes in accordance with Section 4.03(a) hereof if it has filed such reports with the Commission via the EDGAR filing system and such reports are publicly available. 

  
 52 








 (c) The Company shall furnish to the Holders of the Notes and to prospective investors, upon
the requests of such Holders, any information required to be delivered pursuant to Rule 144A(d) (4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act. 

(d) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt
of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers’ Certificates). 
 SECTION 4.04. Compliance Certificate. (a) The
Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under
the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to
the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of
this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and
that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of, interest on the Notes is prohibited or if such event has occurred, a description of the event and
what action the Company is taking or proposes to take with respect thereto. 
 (b) The Company shall, so long as any of the
Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes
to take with respect thereto. 
 SECTION 4.05. Taxes. The Company shall pay, and shall cause each of its Restricted
Subsidiaries to pay, prior to delinquency, all material taxes, charges, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any
material respect to the Holders of the Notes. 
 SECTION 4.06. Waiver of Stay, Extension and Usury Laws. Each of the
Company and the Restricted Subsidiaries covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law
wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Company and the Restricted Subsidiaries (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as
though no such law had been enacted. 

  
 53 








 SECTION 4.07. Restricted Payments. The Company will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without
limitation, any payment in connection with any merger or consolidation involving the Company) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other
than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or payable to the Company or any of its Restricted Subsidiaries); (ii) purchase, redeem or otherwise acquire or retire for value
(including without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company; (iii) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire

(z) the purchase, redemption, defeasance or other acquisition or retirement of Subordinated Indebtedness purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one
year of the date of such purchase, repurchase, redemption, defeasance or other acquisition or retirement; or (iv) make any Restricted Investment (all such payments and other actions set forth in clauses (i) through (iv) above being
collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment: 
 (a) no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof; 
 (b) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period,
have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof; and 

(c) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company or
any of its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (ii), (iii), (iv), (v), (vi), (vii), (viii), (ix), (x) or (xi) of the next succeeding paragraph), is less than the sum of
(i) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from January 1, 2012 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are
available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus (ii) 100% of the aggregate net proceeds received by the Company (including the Fair Market
Value of any property or assets received, less issuance costs) from the issue or sale, in either case, since the Issue Date of (A) Equity 

  
 54 








 
Interests of the Company (other than Disqualified Stock), or (B) Disqualified Stock or debt securities of the Company that have been converted into such Equity Interests (other than Equity
Interests (or Disqualified Stock or convertible or exchangeable debt securities) sold to a Restricted Subsidiary of the Company and other than Disqualified Stock or debt securities that have been converted or exchanged into Disqualified Stock), plus
(iii) in case any Unrestricted Subsidiary has been redesignated a Restricted Subsidiary pursuant to the terms of this Indenture or has been merged, consolidated or amalgamated with or into, or transfers or conveys assets to or is liquidated
into, the Company or a Restricted Subsidiary and provided that no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof, the lesser of (A) the book value (determined in accordance with
GAAP) at the date of such redesignation, combination or transfer of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary (or of the assets transferred or conveyed, as applicable) and
(B) the Fair Market Value of such Investment in such Unrestricted Subsidiary at the time of such redesignation, combination or transfer (or of the assets transferred or conveyed, as applicable), in each case as determined in good faith by the
Board of Directors of the Company, whose determination shall be conclusive and evidenced by a resolution of such Board of Directors and, in each case, after deducting any Indebtedness associated with the Unrestricted Subsidiary so designated or
combined or with the assets so transferred or conveyed, plus (iv) to the extent not already included in Consolidated Net Income for such period, without duplication, in case any Restricted Investment that was made after the Issue Date is sold
or otherwise liquidated or repaid, the lesser of (A) the return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (B) the initial amount of such Restricted Investment, plus
(v) $100,000,000. 
 The foregoing provisions shall not prohibit: (i) the payment of any dividend or consummation of
any irrevocable redemption of debt within 60 days after the date of declaration of the dividend or giving of any such redemption notice, as the case may be, if at the date of declaration or notice, such payment would have complied with the
provisions of this Indenture; (ii) the redemption, repurchase, retirement, defeasance or other acquisition of any Subordinated Indebtedness or Equity Interests of the Company in exchange for, or out of the net cash proceeds of the substantially
concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than any Disqualified Stock); provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase,
retirement, defeasance or other acquisition shall be excluded from clause (c)(ii) of the preceding paragraph; (iii) the defeasance, redemption, repurchase or other acquisition of Subordinated Indebtedness with the net cash proceeds from an
incurrence of Permitted Refinancing Indebtedness; (iv) the payment of any dividend or distribution by a Restricted Subsidiary of the Company to the holders of its common Equity Interests on a pro rata basis; (v) the repurchase, redemption
or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any employee or director of the Company (or any of its Subsidiaries), or any former employee or director of the
Company (or any of its Subsidiaries) issued pursuant to any management equity plan or stock option plan 

  
 55 








 
or any other management or employee benefit plan, agreement or trust; provided, however, that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity
Interests pursuant to this clause (v) shall not exceed $2,000,000 in any twelve-month period; (vi) the declaration and payment of dividends to holders of any class or series of Disqualified Stock of the Company issued in accordance with
the terms of this Indenture to the extent such dividends are included in the definition of “Fixed Charges”; (vii) repurchases of Equity Interests deemed to occur upon the cashless exercise of stock options; (viii) reasonable and
customary directors’ fees to the members of the Company’s Board of Directors, provided that such fees are consistent with past practice; (ix) the purchase, repurchase, redemption, defeasance or other acquisition or retirement
for value of any Indebtedness subordinated in right of payment to the Notes (A) at a purchase price not greater than 101% of the principal amount of such Indebtedness in the event of a Change of Control in accordance with provisions similar to
those of Section 4.15 or (B) at a purchase price greater than 100% of the principal amount thereof in accordance with provisions similar to those of Section 4.10; provided that, prior to or simultaneously with such purchase,
repurchase, redemption, defeasance or other acquisition or retirement, the Company has made the Change of Control Offer or Asset Sale Offer, respectively, as provided in such covenant with respect to the Notes and has completed the repurchase of all
Notes validly tendered for payment in connection with such Change of Control Offer or Asset Sale Offer, respectively; (x) the purchase, redemption or other acquisition of Equity Interests of the Company in an amount which, when taken together
with all other purchases, redemptions or acquisitions made pursuant to this clause (x) since the Issue Date, does not exceed $100,000,000; and (xi) other Restricted Payments since the Issue Date in an aggregate amount at any time
outstanding not to exceed $10,000,000. 
 In determining whether any Restricted Payment is permitted by the foregoing covenant,
the Company may allocate or reallocate all or any portion of such Restricted Payment among clauses (i) through (xi) of the preceding paragraph or among such clauses and the first paragraph of this covenant, provided that at the time
of such allocation or reallocation, all such Restricted Payments, or allocated portions thereof, would be permitted under the various provisions of the foregoing covenant. 
 The amount of all Restricted Payments (other than cash) shall be the Fair Market Value (as evidenced by an Officers’ Certificate delivered to the Trustee) on the date of the Restricted Payment of the
asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. 
 For purposes of making the determination as to whether the designation of a Restricted Subsidiary as an Unrestricted Subsidiary would cause a Default or Event of Default, all outstanding Investments by
the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments or Permitted Investments at the time of such designation. All such outstanding Investments
will be deemed to constitute Investments in an amount equal to the greater of (i) the net book value (determined in accordance with GAAP) of such Investments at the time of such designation, or (ii) the Fair Market Value of such


  
 56 








 
Investments at the time of such designation. Such designation will only be permitted if such Restricted Payment or Permitted Investment would be permitted at such time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Notwithstanding the foregoing, if, at any time, any Unrestricted Subsidiary would fail to meet the requirements under the definition of Unrestricted Subsidiary, it shall
thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary shall be deemed to be incurred as of such date. 
 The Company may designate any Unrestricted Subsidiary to be a Restricted Subsidiary only if (i) immediately after giving effect to such designation, the Company is able to incur at least $1.00 of
additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test under the first paragraph of Section 4.09 and (ii) immediately before and immediately after giving effect to such designation, no Default or Event of Default shall
have occurred and be continuing. 
 SECTION 4.08. Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause to become effective any encumbrance or restriction on the ability of any Restricted Subsidiary of
the Company to: (i) (x) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any other interest or participation in, or measured by,
its profits; provided that the priority of any preferred stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Capital Stock shall not be deemed a restriction on the ability to
make distributions on Capital Stock, or (y) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to
other Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to pay Indebtedness owed to the Company or any of its Restricted Subsidiaries); (ii) make loans or advances to the Company
or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary shall not be deemed a
restriction on the ability to make loans or advances); or (iii) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries, except in each case for such encumbrances or restrictions existing under or by reason
of: (a) Indebtedness or agreements or instruments outstanding on the Issue Date; (b) this Indenture and the Notes; (c) the Credit Agreements as in effect on the Issue Date; (d) applicable law or any applicable rule, regulation or
order of any court or governmental authority; (e) any agreement or instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except
with respect to Indebtedness incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or
assets of the Person or such Person’s subsidiaries, so acquired, provided that in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; (f) restrictions of the nature described in
clause (iii) above by reason of customary non-assignment provisions in 

  
 57 








 
contracts, agreements, and leases entered into in the ordinary course of business and consistent with past practices; (g) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in clause (iii) above on the property so acquired; (h) any restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale
or disposition of Capital Stock or assets of such Restricted Subsidiary pending the closing of such sale or disposition; (i) agreements or instruments relating to Liens permitted to be incurred pursuant to this Indenture that limit the right of
the debtor to dispose of assets securing such Indebtedness; (j) customary encumbrances or restrictions contained in agreements entered into in connection with Hedging Obligations permitted from time to time under this Indenture; (k) any
encumbrance or restriction existing under any instrument or agreement that amends, extends, renews, refinances or replaces the agreements or instruments containing the encumbrances or restrictions in the foregoing clauses (a), (b), (c), (e),
(g) or this clause (k); provided that the terms and conditions of any such encumbrances or restrictions are not in the good faith judgment of the Company materially more restrictive than those contained in such agreement; (l) any
other agreement or instrument governing Indebtedness or other obligations entered into after the Issue Date that either (A) contains encumbrances and restrictions that in the good faith judgment of the Company 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 or (B) contains encumbrances or restrictions that are
customary and do not prohibit (except upon a default or an event of default thereunder) the payment of dividends, loans or advances in an amount sufficient, as determined by the Company in good faith, to make scheduled payments of cash interest and
principal on the notes when due; and (m) provisions with respect to the disposition or distribution of assets or property in partnership agreements, joint venture agreements, asset sale agreements, sale leaseback agreements, stock sale
agreements and other similar agreements entered into in the ordinary course of business. 
 SECTION 4.09. Incurrence of
Indebtedness and Issuance of Preferred Stock. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred
stock; provided, however, that the Company and any Guarantor may incur Indebtedness or issue Disqualified Stock and any Guarantor may issue preferred stock, if, in each case, the Company’s Fixed Charge Coverage Ratio would have
been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom). 

The provisions of the first paragraph of this covenant shall not apply to the incurrence of any of the following items of Indebtedness
(collectively, “Permitted Debt”): 
 (i) the incurrence by the Company or any of its Restricted
Subsidiaries of Indebtedness and letters of credit pursuant to one or more Credit Facilities (with letters of credit being deemed to have an outstanding amount equal to the maximum potential liability of the Company thereunder) in an


  
 58 








 
aggregate principal amount at any one time outstanding under this clause (i) not to exceed the greater of (A) $350,000,000, (B) 25% of Consolidated Tangible Assets or (C) the
aggregate principal amount of Indebtedness outstanding under this clause (i) immediately prior to such incurrence; 
 (ii) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes (but not Additional Notes) and the Subsidiary Guarantees;

this Section 4.09; 
 (iv) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted
Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund, Indebtedness that was permitted by this Indenture to be incurred pursuant to clause (ii), (iii), this clause
(iv) or clause (xiii) or pursuant to the first paragraph of this Section 4.09; 
 (v) the
incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (i) if the Company or any Guarantor is the
obligor on such Indebtedness and the obligee is a Restricted Subsidiary that is not a Guarantor, such Indebtedness is expressly subordinate to the payment in full of all Obligations with respect to the Notes and (ii) (A) any subsequent
issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either
the Company or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be; 

(vi) the incurrence by the Company or any of its Restricted Subsidiaries of Purchase Money Indebtedness (or Capital Lease
Obligations), including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace Purchase Money Indebtedness incurred pursuant to this clause (vi); 

(vii) the incurrence by the Company or any of its Restricted Subsidiaries of obligations in the ordinary course of
business under (A) trade letters of credit which are to be repaid in full not more than one year after the date on which such Indebtedness is originally incurred to finance the purchase of goods by the Company or a Restricted Subsidiary of the
Company; (B) standby letters of credit issued for the purpose of supporting (1) workers’ compensation liabilities of the Company or any of its Restricted Subsidiaries, or (2) performance, payment, deposit or surety obligations of
the Company or any of its Restricted Subsidiaries; and (C) bid, advance payment and performance bonds and surety bonds of the Company and its Restricted Subsidiaries, and refinancings thereof; 

  
 59 








 (viii) the incurrence by the Company or any of its Restricted Subsidiaries
of Hedging Obligations not for speculative purposes and incurred in the ordinary course of business; 
 (ix) the
guarantee by the Company or any Restricted Subsidiary of the Company of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this covenant; provided that the guarantee
of any Indebtedness under this clause (ix) by a Restricted Subsidiary of the Company that ceases to be a Restricted Subsidiary shall be deemed a Restricted Investment (or, if applicable, a Permitted Investment) at the time such Restricted
Subsidiary’s status terminates in an amount equal to the maximum principal amount so guaranteed, for so long as, and to the extent that, such guarantee remains outstanding; 

(x) the issuance by a Restricted Subsidiary of the Company of preferred stock to the Company or to any of its Restricted
Subsidiaries; provided, however, that any subsequent event or issuance or transfer of any Equity Interests that results in the owner of such preferred stock ceasing to be the Company or any of its Restricted Subsidiaries or any
subsequent transfer of such preferred stock to a Person, other than the Company or one of its Restricted Subsidiaries, shall be deemed to be an issuance of preferred stock by such Subsidiary that was not permitted by this clause (x); 

(xi) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a
bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 

(xii) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness consisting of guarantees,
indemnities, holdbacks or obligations in respect of purchase price adjustments in connection with the acquisition or disposition of any business, assets or Capital Stock of the Company or any Restricted Subsidiary; provided that such
Indebtedness is not reflected on the balance sheet of the Company or any Restricted Subsidiary; 
 (xiii)
Indebtedness of Persons incurred and outstanding on the date on which such Person was acquired by the Company or any Restricted Subsidiary, or merged or consolidated with or into the Company or any Restricted Subsidiary (other than Indebtedness
incurred in connection with, or in contemplation of, such acquisition, merger or consolidation); provided, however, that at the time such Person or assets is/are acquired by the Company or a Restricted Subsidiary, or merged or
consolidated with the Company or any Restricted Subsidiary, and after giving pro forma effect to the incurrence of such Indebtedness pursuant to this 

  
 60 








 
clause (xiii) and any other related Indebtedness, either (A) the Company would have been able to incur $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
under the first paragraph of this Section 4.09; or (B) the Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries is no less than the Fixed Charge Coverage Ratio immediately prior to such acquisition, merger or
consolidation; and 
 (xiv) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
(in addition to Indebtedness permitted by any other clause of this paragraph) in an aggregate principal amount (or accreted value, as applicable) at any time outstanding not to exceed $30,000,000. 

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 Debt described in clauses (i) through (xiv) above or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company may, in its sole discretion, divide and classify such item of
Indebtedness at the time of incurrence or later classify, reclassify or divide such item of Indebtedness in any manner that complies with this covenant and such item of Indebtedness shall be treated as having been incurred pursuant to only one of
such clauses or pursuant to the first paragraph hereof. Accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of
this covenant. In addition, the maximum amount of Indebtedness that the Company and its Restricted Subsidiaries may incur pursuant to this covenant will not be deemed to be exceeded, with respect to any outstanding Indebtedness, due solely to the
result of fluctuations in the exchange rates of currencies. 
 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 Permitted 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 Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

 SECTION 4.10. Asset Sales. The Company will not, and will not permit any of its
Restricted Subsidiaries to, engage in an Asset Sale unless (i) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary from such Asset Sale and all other Asset Sales on a cumulative basis since the Issue
Date is in the form of cash or Cash Equivalents; provided that, for purposes of this provision, the amount of each of the following shall be deemed to be cash: (a) any liabilities (as shown on the Company’s or such Restricted
Subsidiary’s most recent balance sheet), of the Company or any Restricted Subsidiary of the Company (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are
assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; (b) any securities, notes or other obligations received by the Company or
any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash (to the extent of the cash received) within 270 days of the consummation of such Asset Sale; (c) any Capital Stock or
assets of the kind referred to in clauses (b), (c) or (d) of the third paragraph of this Section 4.10; and (d) accounts receivables of a business retained by the Company or any of its Restricted Subsidiaries following the sale of
such business; provided that (i) such accounts receivables are not more than 60 days past due and (ii) do not have a payment date greater than 90 days from the date of the invoice creating such accounts receivable. 

Any Asset Sale pursuant to a condemnation, appropriation or other similar taking, including by deed in lieu of condemnation, shall not be
required to satisfy the conditions set forth in clauses (i) and (ii) of the first paragraph of this Section 4.10. 
 Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or such Restricted Subsidiary, as the case may be, may apply such Net Proceeds, at its option, (a) to repay
Indebtedness for borrowed money other than Subordinated Indebtedness, (b) to acquire a controlling interest in another business or all or substantially all of the assets of a business, engaged in a Permitted Business, (c) to make capital
expenditures in a Permitted Business or (d) to acquire other long-term assets that are used or useful in a Permitted Business, provided that the Company or such Restricted Subsidiary will have complied with clause (b), (c) or
(d) if, within 365 days of such Asset Sale, the Company or such Restricted Subsidiary shall have commenced and not completed or abandoned an investment in compliance with clause (b), (c) or (d) and such Investment is substantially
completed within 180 days after the first anniversary of such Asset Sale. Pending the final application of any such Net Proceeds, the Company may temporarily reduce Indebtedness under any Credit Facility or otherwise invest such Net Proceeds in any
manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this paragraph shall be deemed to constitute “Excess Proceeds.” When the aggregate
amount of Excess Proceeds exceeds $30,000,000, the Company shall be required to make an offer to all Holders of Notes and other Indebtedness that ranks by its terms pari passu in right of payment with the Notes and the terms of which contain
substantially similar requirements with respect to the application of net proceeds from Asset Sales as are contained in this Indenture (an “Asset Sale Offer”) to purchase on a pro rata basis the


  
 62 








 
maximum principal amount of the Notes (and such other Indebtedness), that is an integral multiple of $1,000, that may be purchased out of the Excess Proceeds, at an offer price in cash in an
amount equal to 100% of the principal amount thereof plus accrued and unpaid interest thereon to the date of purchase, in accordance with the procedures set forth in Section 3.09 hereof. To the extent that the aggregate amount of Notes and
other such Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company or such Restricted Subsidiaries, as the case may be, may use any remaining Excess Proceeds for general corporate purposes. If the
aggregate principal amount of Notes surrendered by Holders thereof exceeds the amount of Excess Proceeds available to repurchase Notes, the Trustee shall select the Notes to be purchased on a pro rata basis. Upon completion of an offer to purchase
as described in the immediately preceding sentence, the amount of Excess Proceeds shall be reset at zero. 
 The Company shall
comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with an Asset Sale Offer. 

SECTION 4.11. Transactions with Affiliates. The Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, loan, advance or
guarantee with, or for the benefit of, any Affiliate of any such Person (each of the foregoing, an “Affiliate Transaction”), unless (i) the terms of such Affiliate Transaction are not materially less favorable to the Company or
such Restricted Subsidiary, as the case may be, than those that could reasonably be expected to have been obtained in a comparable transaction at the time of such transaction in arm’s length dealings with a Person who is not such an Affiliate
or are otherwise fair to the Company or such Restricted Subsidiary from a financial point of view; and (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$25,000,000, a majority of the directors of the Company disinterested with respect to such Affiliate Transaction have determined in good faith that the criteria set forth in clause (i) are satisfied and have approved the relevant Affiliate
Transaction as evidenced by a resolution of the Board of Directors delivered to the Trustee. 
 None of the following shall be
deemed to be Affiliate Transactions: (1) any employment agreement or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business; (2) transactions between or among the Company and/or its
Restricted Subsidiaries; (3) transactions with a Person that is an Affiliate of the Company solely because the Company owns an Equity Interest in, or controls, such Person; (4) sales of Equity Interests (other than Disqualified Stock) to
Affiliates of the Company; (5) Permitted Investments or Restricted Payments that are permitted by Section 4.07 hereof; (6) advances to employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures
in the ordinary course of business and consistent with past practices; (7) maintenance in the ordinary course of business of benefit programs or arrangements for employees, officers or directors, including vacation plans, health and life
insurance plans, deferred compensation plans 

  
 63 








 
and retirement or savings plans and similar plans; (8) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of,
employment agreements or stock option or stock ownership plans approved by the Board of Directors; (9) fees and compensation paid to, and indemnity provided on behalf of, officers, directors or employees of the Company or any of its Restricted
Subsidiaries, to the extent such fees and compensation are reasonable and customary; and (10) the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any written agreement to which the Company or
any of its Restricted Subsidiaries is a party as in effect on the Issue Date. 
 SECTION 4.12. Liens. The Company will
not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien (the “Initial Lien”) on any asset now owned or hereafter acquired, or any income or profits therefrom
or assign or convey any right to receive income therefrom, except Permitted Liens, to secure (a) any Indebtedness of the Company, unless prior to, or contemporaneously therewith, the Notes are equally and ratably secured, or (b) any
Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary Guarantees are equally and ratably secured; provided, however, that if such Indebtedness is expressly subordinated to the Notes or any
Subsidiary Guarantees, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Notes or any Subsidiary Guarantees, as the case may be, with the same relative priority as such Indebtedness has with respect to the
Notes or any Subsidiary Guarantees. 
 Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding
sentence shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. 
 SECTION 4.13. Business Activities. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, engage in any line of business other than a Permitted
Business, except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. 

SECTION 4.14. Corporate Existence. Subject to Articles 5 and 10 hereof, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the
same may be amended from time to time) of the Company or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided, however, that
the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 

  
 64 








 SECTION 4.15. Offer to Repurchase upon Change of Control. (a) Upon the
occurrence of a Change of Control, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or integral multiples of $1,000 in excess thereof, as applicable) of such Holder’s Notes pursuant
to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon, to the date of purchase (the “Change of
Control Payment”). 
 No later than 30 days following any Change of Control, the Company shall mail a notice to each
Holder describing: (i) the transaction or transactions that constitute the Change of Control and that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;
(ii) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); (iii) that any Note not tendered
will continue to accrue interest; (iv) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of
Control Payment Date; (v) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of
the Notes 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 Change of Control Payment Date; (vi) that Holders will be entitled to withdraw their election
if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal
amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and (vii) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal
amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or integral multiples of $1,000 in excess thereof, as applicable. The Company shall comply with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control. 

(b) On the Change of Control Payment Date, the Company will, to the extent lawful, (i) accept for payment all Notes or portions
thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered and (iii) deliver or cause to be
delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent will promptly mail to each Holder of
Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the
Notes surrendered, if any; provided that each such new Note will be in a minimum denomination of $2,000 and integral multiples of $1,000. Prior to complying with the 

  
 65 








 
provisions of this Section 4.15, but in any event within 90 days following a Change of Control, the Company will either repay all outstanding Indebtedness or obtain the requisite consents,
if any, under all agreements governing outstanding Indebtedness to permit the repurchase of Notes required by this covenant. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change
of Control Payment Date. 
 (c) The Company will not be required to make a Change of Control Offer upon a Change of Control if
it has given a notice of redemption with respect to all outstanding Notes in accordance with the requirements set forth herein which is or has become unconditional (unless it defaults in making payment therefor), or if a third party makes the Change
of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change
of Control Offer. A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the
Change of Control Offer. 
 (d) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly
tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such
Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain
outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, 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). 
 SECTION 4.16. Subsidiary Guarantees of Certain Indebtedness. No Restricted Subsidiary of the Company may guarantee any Indebtedness of the Company or of a Subsidiary Guarantor, including
Indebtedness under any Credit Facility, unless such Restricted Subsidiary (i) executes and delivers to the Trustee a supplemental indenture in form and substance satisfactory to the Trustee providing that such Restricted Subsidiary shall become
a Guarantor under this Indenture and evidencing such Subsidiary Guarantee of the Notes in accordance with Article 10 hereof and (ii) delivers an Opinion of Counsel to the effect, that such supplemental indenture has been duly authorized and
executed by such Restricted Subsidiary. Neither the Company nor any Guarantor shall be required to make a notation on the Notes to reflect any such subsequent Subsidiary Guarantee. Nothing in this Section 4.16 shall be construed to permit any
Restricted Subsidiary of the Company to incur Indebtedness otherwise prohibited by Section 4.09 hereof. 

  
 66 








 SECTION 4.17. Changes in Covenants When Notes Rated Investment Grade. If at any time
that the Notes have a rating equal to or greater than BBB- by S&P and Baa3 by Moody’s (each such rating, an “Investment Grade Rating”) and no Default or Event of Default shall have occurred and be continuing, then,
beginning on the day such Investment Grade Rating is attained, the Company and its Subsidiaries shall no longer be subject to Sections 3.09, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.13 and clause (iv) of Section 5.01 herein, provided,
however, that the provisions described under Sections 4.03, 4.12, 4.15, 4.16, 5.01 (other than clause (iv) of Section 5.01) and 10.01 herein shall not be so terminated. 

ARTICLE 5 

Successors Section 
 SECTION 5.01. Merger, Consolidation, or Sale of Assets. The Company will not consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another Person unless (i) the Company is the surviving corporation or the entity or the Person formed by or
surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is an entity organized or existing under the laws of the United States,
any state thereof or the District of Columbia; and if such entity is not a corporation, a co-obligor of the Notes is a corporation organized or existing under such laws; (ii) the Person formed by or surviving any such consolidation or merger
(if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Notes and this Indenture pursuant to a supplemental
indenture in a form reasonably satisfactory to the Trustee; (iii) immediately before and after such transaction no Default or Event of Default shall have occurred and be continuing; and (iv) except in the case of a merger of the Company
with or into a Restricted Subsidiary, the Company or the entity or Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition shall
have been made will, at the time of such transaction and after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable four-quarter period, (x) be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 4.09 or (y) have a Fixed Charge Coverage Ratio that is no less than the Fixed Charge Coverage Ratio of the Company immediately prior
to such transaction. 
 SECTION 5.02. Successor Corporation Substituted. Upon any consolidation or merger, or any sale,
assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which the
Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that 

  
 67 








 
from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer
instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, and except in the case of
a lease, the Company shall be released from all Obligation under this Indenture and the Notes. 
 ARTICLE 6 

Defaults and Remedies Section 
 SECTION 6.01. Events of Default. An “Event of Default” occurs if: 
 (a) the Company defaults in the payment when due of interest on the Notes and such default continues for 30 days; 
 (b) the Company defaults in the payment when due of the principal of or premium, if any, on the Notes; 
 (c) the Company fails to comply with its obligations set forth in Section 5.01; 
 (d) the Company or any of its Restricted Subsidiaries fails to comply with any of the provisions of Sections 3.09, 4.10 or 4.15 (other than a failure to purchase Notes) hereof for 30 days after notice to
the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding; 
 (e) the Company or any of its Restricted Subsidiaries fails to observe or perform any covenant, representation, warranty or other agreement in this Indenture, the Notes or the Subsidiary Guarantees (other
than the provisions expressly set forth in clause (d) above) for 60 days (or 120 days with respect to a failure to comply with Section 4.03) after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding; 
 (f) a default occurs under any mortgage, indenture or instrument under
which there is issued or is secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries) whether such
Indebtedness or guarantee now exists, or is created after the Issue Date, which default (i) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in
such Indebtedness on the date of such default (a “Payment Default”) or (ii) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates without duplication $25,000,000 or more and such default shall not have been
cured or acceleration rescinded within fifteen Business Days after such occurrence; 

  
 68 








 (g) a final judgment or final judgments for the payment of money in an
aggregate amount in excess of $25,000,000 (excluding amounts covered by insurance) shall be rendered by a court or courts of competent jurisdiction against the Company or any of its Restricted Subsidiaries and such judgment or judgments remain
unpaid, undischarged or unstayed for a period of 60 days; 
 (h) the Company or any of its Restricted
Subsidiaries or any of its Significant Subsidiaries or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of the Bankruptcy Code: 

(i) commences a voluntary case, 
 (ii) consents to the entry of an order for relief against it in an involuntary case, 
 (iii) consents to the appointment of a custodian of it or for all or substantially all of its property, 
 (iv) makes a general assignment for the benefit of its creditors, or 
 (v) generally is not paying its debts as they become due; 
 (i) a
court of competent jurisdiction enters an order or decree under the Bankruptcy Code that: 
 (i) is for relief
against the Company or any of its Restricted Subsidiaries or any of its Significant Subsidiaries or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary, in an involuntary case; 

(ii) appoints a Custodian of the Company or any of its Restricted Subsidiaries or any of its Significant Subsidiaries or
any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary, or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries or any of its Significant Subsidiaries or any group
of Subsidiaries that, when taken together, would constitute a Significant Subsidiary; or 
 (iii) orders the
liquidation of the Company or any of its Restricted Subsidiaries or any of its Significant Subsidiaries or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary; and the order or decree remains unstayed and
in effect for 60 consecutive days; or 

  
 69 








 (j) except as permitted herein, any Subsidiary Guarantee of a Restricted
Subsidiary that constitutes a Significant Subsidiary or a group of Restricted Subsidiaries, that taken together, would constitute a Significant Subsidiary shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any
reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee (other than by reason of the termination of this Indenture or the release
of any such Subsidiary Guarantee in accordance with this Indenture). 
 SECTION 6.02. Acceleration. If any Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default specified in clause (h) or (i) of Section 6.01 hereof occurs with respect to the Company, all outstanding Notes will become due and payable without further action or notice. The Holders of a majority in principal
amount of the Notes by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of
principal or interest that has become due solely because of acceleration. Holders of the Notes may not enforce this Indenture or the Notes except as provided herein. 
 SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, interest on the Notes or to enforce
the performance of any provision of the Notes or this Indenture. 
 The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 

SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Notes then outstanding by
notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of interest on, or the principal of,
the Notes; provided, however, that the Holders of a majority in aggregate principal amount of then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such
acceleration, to the extent permitted by applicable law. Upon any 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 impair any right consequent thereon. 

  
 70 








 SECTION 6.05. Control by Majority. Holders of a majority in principal amount of the
then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction
that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 

SECTION 6.06. Limitation on Suits. A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if:

 (a) the Holder of a Note has previously given to the Trustee written notice of a continuing Event of Default;

 (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to
the Trustee to pursue the remedy; 
 (c) such Holder of a Note or Holders of Notes offer and, if requested,
provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense to be incurred in compliance with such request; 
 (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and 

(e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the
Trustee a direction inconsistent with the request. 
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of
a Note or to obtain a preference or priority over another Holder of a Note or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 

SECTION 6.07. Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal, premium and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such
payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 SECTION
6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against
the Company for the whole amount of principal of, premium and interest remaining

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 is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property
and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments
to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts
due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of
any Holder in any such proceeding. 
 SECTION 6.10. Priorities. If the Trustee collects any money pursuant to this
Article, it shall pay out the money in the following order: 
 First: to the Trustee, its agents and attorneys
for amounts due under Section 7.07 hereof, including payment of all compensation, expense, and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and interest, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and interest, respectively; and 
 Third: to the Company or to such party as a court of competent jurisdiction shall direct. 

  
 72 








 The Trustee may fix a record date and payment date for any payment to
Holders of Notes 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 a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to
pay the cost of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding
Notes. 
 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 its exercise, as a prudent person would exercise or use under the
circumstances in the conduct of such person’s own affairs. 
 (b) Except during the continuance of an Event of Default:

 (i) The Trustee need perform only those duties that are specifically set forth in this Indenture and the TIA
and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee. To the extent of any conflict between the duties of the Trustee hereunder and under the TIA, the TIA shall control. 

(ii) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not
they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 
 (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 

(i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01; 

  
 73 








 (ii) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof. 

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), and (c) of this Section 7.01. 
 (e) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee security
and indemnity satisfactory to it against any loss, liability or expense. 
 (f) The Trustee shall not be liable for interest on
any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

SECTION 7.02. Rights of Trustee. (a) The Trustee may conclusively rely upon any document (whether in its original or
facsimile form) 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, it may require an Officers’ Certificate or an Opinion of Counsel or both. The
Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

(c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent
appointed with due care. 
 (d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it
believes to be authorized or within the rights or powers conferred upon it by this Indenture. 
 (e) Unless otherwise
specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company. 

  
 74 








 (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 unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities (including fees and expenses of its
agents and counsel) that might be incurred by it in compliance with such request or direction. 
 SECTION 7.03. Individual
Rights of Trustee. The Trustee, any Paying Agent, any authenticating agent or registrar in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with
the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee or resign.
Any Agent may do the same with like rights and duties. The Trustee is also 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 the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from
the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it
shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 

SECTION 7.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is actually known to a
Responsible Officer of the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium or
interest, if any, on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 

SECTION 7.06. Reports by Trustee to Holders of the Notes. Within 60 days after each May 15 beginning with the May 15
following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event
described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all
reports as required by TIA Section 313(c). 
 A copy of each report at the time of its mailing to the Holders of Notes
shall be mailed to the Company and filed with the Commission and each stock exchange on which the Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock
exchange or delisted therefrom. 

  
 75 








 SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from
time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express
trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 The Company shall indemnify each of the
Trustee and any predecessor Trustee against any and all losses, liabilities, claims, damages or expenses (including taxes other than taxes based upon the income or gross receipts of the Trustee) incurred by it arising out of or in connection with
the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether asserted by the
Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability, claim, damage or expense may be attributable to its
negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend
the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which
consent shall not be unreasonably withheld. 
 The obligations of the Company under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture. 
 To secure the Company’s payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this
Indenture. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h)
or (i) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under the Bankruptcy Code. 

The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable. 

  
 76 








 SECTION 7.08. Replacement of Trustee. A resignation or removal of the Trustee and
appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. 
 The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding
Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.10 hereof, 

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

(d) the Trustee 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 Company 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 then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company, or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply
with Section 7.10 hereof, such Holder of a Note may, at the expense of the Company, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders
of the Notes. 
 The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee,
provided that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s
obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 

  
 77 








 SECTION 7.09. Successor Trustee by Merger, Etc. If the Trustee consolidates, merges
or converts into, or transfers all or substantially all of its corporate trust business (including the administration of this Indenture) to, another corporation, the successor corporation without any further act shall be the successor Trustee.

 SECTION 7.10. Eligibility, Disqualification. There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities
and that has (or, in the case of a Trustee that is a subsidiary of a bank holding company, its bank holding company parent shall have) a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of
condition. 
 This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1),
(2) and (5). The Trustee is subject to TIA Section 310(b). 
 SECTION 7.11. Preferential Collection of Claims
Against Company. The Trustee is subject to 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. 
 ARTICLE 8 
 Legal Defeasance and Covenant Defeasance 
 SECTION 8.01. Option to
Effect Legal Defeasance or Covenant Defeasance. The Company may, at its option evidenced by an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance
with the conditions set forth below in this Article 8. 
 SECTION 8.02. Legal Defeasance and Discharge. Upon the
Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from
its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”) except as provided below in this Section 8.02. For this purpose, Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the
other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in
Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such 

  
 78 








 
Notes when such payments are due, (b) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and the Company’s obligations in connection therewith, and (d) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding
the prior exercise of its option under Section 8.03 hereof. 
 SECTION 8.03. Covenant Defeasance. Upon the
Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under
the covenants contained in Sections 3.09, 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof, Article 5 hereof and Section 10.03 hereof with respect to the outstanding Notes on and after the date the
conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders
(and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company 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 of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under
Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(c) through 6.01(g) hereof and 6.01(j) hereof shall not constitute
Events of Default. 
 SECTION 8.04. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to
the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: 
 In order to exercise either Legal
Defeasance or Covenant Defeasance: 
 (a) the Company must irrevocably deposit with the Trustee, in trust, for
the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to
pay the principal of, premium, if any, and interest on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a
particular redemption date; 

  
 79 








 (b) in the case of an election under Section 8.02 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or
(B) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will
not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred; 
 (c) in the case of an election under Section 8.03 hereof, the Company shall
have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of
such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default
or Event of Default resulting from the borrowing of funds to be applied to such deposit); 
 (e) such Legal
Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Restricted Subsidiaries is a party or
by which the Company or any of its Restricted Subsidiaries is bound; 
 (f) the Company shall deliver to the
Trustee an Officers’ Certificate stating that, at the time the Company made the deposit, it was not insolvent and that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the
Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and 
 (g) the Company shall deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the
Covenant Defeasance have been complied with. 
 SECTION 8.05. Deposited Money and Government Securities to be Held in Trust;
Other Miscellaneous Provisions. Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 8.05, the “Trustee”) pursuant to Section 8.04 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


  
 80 








 
and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or
non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the
outstanding Notes. 
 Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the
Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance. 
 SECTION 8.06. Repayment to Company. Any money deposited with the Trustee or
any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and
payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a secured creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times or The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 SECTION 8.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the
case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if the Trustee is required by any court or governmental authority to return to the Company,
or any liquidator or similar official acting in relation to the Company, the Company’s deposit pursuant to Section 8.02 or 8.03 hereof, then the Company’s obligations under this Indenture and the Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 

  
 81 








 
8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE 9 

Amendment, Supplement and Waiver Section 
 SECTION 9.01. Without Consent of Holders of Notes. Notwithstanding Section 9.02 hereof, the Company and the Trustee may amend or supplement this Indenture, the Notes or the Subsidiary
Guarantees without the consent of any Holder of a Note: 
 (a) to cure any ambiguity, defect or inconsistency;

 (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the
provisions of Article 2 hereof (including the related definitions) in a manner that does not materially adversely affect any Holder; 
 (c) to provide for the assumption of the Company’s obligations to the Holders of the Notes in the case of a merger, consolidation or sale of assets of the Company pursuant to Article 5 hereof or of
any Guarantor pursuant to Article 10 hereof or to add any Person as a Guarantor hereunder; 
 (d) to make any
change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any such Holder; 

(e) to comply with requirements of the Commission in order to effect or maintain the qualification of this Indenture under
the TIA; 
 (f) to provide for Guarantees of the Notes or to release Guarantees in accordance with this
Indenture; 
 (g) to secure the Notes; 

(h) to provide for Additional Notes in accordance with this Indenture; or 

(i) to conform the text of this Indenture, the Subsidiary Guarantees or the Notes to any provision of the
“Description of the Notes” in the Offering Circular to the extent that such provision in the “Description of the Notes” was intended to be a substantially verbatim recitation of a provision of this Indenture, the Subsidiary
Guarantees or the Notes, as applicable, as evidenced by an Officers’ Certificate of the Company delivered to the Trustee. 

  
 82 








 Upon the request of the Company authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture authorized or permitted by the terms of
this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties,
liabilities or immunities under this Indenture or otherwise. 
 SECTION 9.02. With Consent of Holders of Notes. Except as
provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including Sections 3.09, 4.10 and 4.15 hereof), the Subsidiary Guarantees and the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.04 and
6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a tender offer
or exchange offer for the Notes). 
 Upon the request of the Company authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by a Responsible Officer of the Trustee of the documents described in
Section 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture affects the Trustee’s own rights, duties, liabilities or immunities under
this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. 
 It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such
consent approves the substance thereof. 
 After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding may waive compliance in a particular
instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder): 

(a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver of any provision
of this Indenture, the Notes or any Subsidiary Guarantee; 

  
 83 








 (b) reduce the principal of or change the fixed maturity of any Note or
alter or waive in any manner that adversely affects the rights of any Holder of Notes any of the provisions with respect to the redemption of the Notes except as provided above with respect to Sections 3.09, 4.10 and 4.15 hereof and the related
definitions; 
 (c) reduce the rate of or change the time for payment of interest, including default interest on
any Note; 
 (d) waive a Default or Event of Default in the payment of principal of or premium, if any, or
interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

 (e) make any Note payable in money other than that stated in the Notes; 

(f) make any change that adversely affects the rights of any Holder of Notes in the provisions of this Indenture relating
to waivers of past Defaults or make any change to the rights of Holders of Notes to receive payments of principal of or interest on the Notes; 
 (g) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 and 4.15 hereof); or 

(h) make any change in Section 6.04 or 6.07 hereof or in the foregoing amendment and waiver provisions. 

SECTION 9.03. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Notes shall be set forth
in an amended or supplemental Indenture that complies with the TIA as then in effect. 
 SECTION 9.04. Revocation and Effect
of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of
revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

  
 84 








 SECTION 9.05. Notation on or Exchange of Notes. The Trustee may place an appropriate
notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company, in exchange for all Notes, may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. 

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 9.06. Trustee to Sign Amendments, Etc. The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture
which affects the Trustee’s own rights, duties, liabilities or immunities under this Indenture or otherwise. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 

ARTICLE 10 

Guarantees 
 SECTION 10.01. Subsidiary Guarantees. Subject to Sections 10.04 and 10.05 hereof, any Restricted Subsidiary that becomes a Guarantor shall, jointly and severally, unconditionally guarantee to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, the Notes and the Obligations of the Company hereunder and thereunder, that: 

(a) the principal of, premium, if any, interest on the Notes will be promptly paid in full when due, subject to any
applicable grace period, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal, premium, if any (to the extent permitted by law), interest on any interest, if any, on the Notes, and all other payment
Obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and 

(b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will be
promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise. 

Failing payment when so due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be
jointly and severally obligated to pay the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary 

  
 85 








 
Guarantees, and shall entitle the Holders to accelerate the Obligations of the Guarantors hereunder in the same manner and to the same extent as the Obligations of the Company. The Guarantors
shall agree that their Obligations hereunder shall be unconditional, irrespective of the validity 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 Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor
shall waive diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and
shall covenant that its Subsidiary 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
Company, the Guarantors, or any Note Custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary
Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor shall agree that it shall not be entitled to, and shall waive, any right to exercise any right of subrogation in relation to the Holders in
respect of any Obligations guaranteed by the Subsidiary Guarantee, except as provided under Section 10.05 hereof. Each Guarantor shall further agree that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other
hand, (x) the maturity of the Obligations guaranteed by the Subsidiary Guarantee may be accelerated as provided in Article 6 hereof for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Obligations guaranteed thereby, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article 6 hereof, such Obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor pursuant to Section 10.05 after the Notes and the Obligations
hereunder shall have been paid in full to the Holders under the Subsidiary Guarantees. 
 SECTION 10.02. Execution and
Delivery of Subsidiary Guarantee. To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Guarantor shall (i) execute and deliver a supplemental indenture substantially in the form of Exhibit D hereto or such other
form reasonably satisfactory to the Trustee, which supplemental indenture shall be entered into in accordance with Section 4.16 hereof and shall be executed on behalf of such Guarantor, by manual or facsimile signature, by an Officer of such
Guarantor and (ii) deliver an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized and executed by such Guarantor. 
 Each Guarantor shall agree that its Subsidiary Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such
Subsidiary Guarantee. 

  
 86 








 If an officer who shall have signed this Indenture or a supplemental indenture no longer
holds that office at the time the Trustee authenticates the Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee shall be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors.

 SECTION 10.03. Guarantors May Consolidate, Etc., on Certain Terms. (a) Nothing contained in this Indenture shall
prohibit a merger between a Guarantor and another Guarantor or a merger between a Guarantor and the Company. 
 (b) Except in
circumstances in which the Subsidiary Guarantee of such Guarantor will be released under Section 10.04, no Guarantor shall consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) or sell all or
substantially all of its assets to another corporation, Person or entity whether or not affiliated with such Guarantor unless, (i) subject to the following paragraph, the Person formed by or surviving any such merger or consolidation, or to
which such sale of assets shall have been made (if other than such Guarantor) assumes all the Obligations of such Guarantor, pursuant to a supplemental indenture substantially in the form of Exhibit D hereto or such other form reasonably
satisfactory to the Trustee, under this Indenture; and (ii) immediately after giving effect to such transaction, no Default or Event of Default exists. 
 Notwithstanding the foregoing paragraph, (i) any Guarantor may consolidate with, merge into or transfer all or a part of its properties and assets to the Company or any other Guarantor and
(ii) any Guarantor may merge with a Restricted Subsidiary of the Company that has no significant assets or liabilities and was incorporated solely for the purpose of re-incorporating or re-domesticating such Guarantor in another State of the
United States or, if such Guarantor was organized under the laws of a jurisdiction other than a State of the United States, in any foreign country that is a member of the OECD; provided that, in each case, such merged entity continues to be a
Guarantor. 
 (c) In the case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor
Person, by supplemental indenture, executed and delivered to the Trustee and substantially in the form of Exhibit D hereto or such other form reasonably satisfactory to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and
punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a
Guarantor. Such successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the
Trustee. All of the Subsidiary Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as
though all of such Subsidiary Guarantees had been issued at the date of the execution hereof. 

  
 87 








 SECTION 10.04. Releases of Guarantees. In the event of (i) the release by the
lenders under all Indebtedness of the Company and other Guarantors of all guarantees of (including all Liens on the property and assets of such Guarantor relating thereto) such Indebtedness by a Guarantor, (ii) a sale or other disposition of
all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of Capital Stock of any Guarantor in compliance with this Indenture such that such Guarantor is no longer a Restricted Subsidiary of the
Company, (iii) proper designation of such Guarantor as an Unrestricted Subsidiary, (iv) Legal or Covenant Defeasance in accordance with this Indenture, (v) satisfaction and discharge under Article 11 of this Indenture, or
(vi) dissolution of such Guarantor provided that no Default or Event of Default has occurred and is continuing, then in each case such Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee and this Indenture.
Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect of the foregoing, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its Obligation under its
Subsidiary Guarantee. Any Guarantor not released from its Obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of, premium, if any, interest on the Notes and for the other Obligations of such Guarantor
under this Indenture as provided in this Article 10. 
 SECTION 10.05. Limitation on Guarantor Liability;
Contribution. For purposes hereof, each Guarantor’s liability shall be limited to the lesser of (i) the aggregate amount of the Obligations of the Company under the Notes and this Indenture and (ii) the amount, if any, which would
not have (A) rendered such Guarantor “insolvent” (as such term is defined in the Bankruptcy Code and in the Debtor and Creditor Law of the State of New York) or (B) left such Guarantor with unreasonably small capital at the time
its Subsidiary Guarantee of the Notes was entered into; provided that, it will be a presumption in any lawsuit or other proceeding in which a Guarantor is a party that the amount guaranteed pursuant to the Subsidiary Guarantee is the amount
set forth in clause (i) above unless any creditor, or representative of creditors of such Guarantor, or debtor in possession or trustee in bankruptcy of the Guarantor, otherwise proves in such a lawsuit that the aggregate liability of the
Guarantor is the amount set forth in clause (ii) above. In making any determination as to solvency or sufficiency of capital of a Guarantor in accordance with the previous sentence, the right of such Guarantor to contribution from other
Guarantors as set forth below, and any other rights such Guarantor may have, contractual or otherwise, shall be taken into account. 
 In order to provide for just and equitable contribution among the Guarantors, the Guarantors shall agree, inter se, that in the event any payment or distribution is made by any Guarantor (a
“Funding Guarantor”) under its Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from all other Guarantors in a pro rata amount based on the Adjusted Net Assets of each Guarantor (including the Funding
Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Notes or any other Guarantor’s Obligations with respect to its Subsidiary Guarantee.


  
 88 








 SECTION 10.06. Trustee to Include Paying Agent. In case at any time any Paying Agent
other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and
including such Paying Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in this Article 10 in place of the Trustee. 
 ARTICLE 11 
 Satisfaction and Discharge Section 

SECTION 11.01. Satisfaction and Discharge. This Indenture will be discharged and will cease to be of further effect as to all
Notes issued hereunder, when (a) either (i) all such Notes 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 and
thereafter repaid to the Company) have been delivered to the Trustee for cancellation; or (ii) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by
reason of the making of a notice of redemption or otherwise and the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. Dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on such Notes not delivered to the Trustee for cancellation
for principal, premium, if any, and accrued interest to the date of maturity or redemption; (b) the Company has paid or caused to be paid all sums payable by it under this Indenture; and (c) the Company has delivered irrevocable
instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Notes at maturity or the redemption date, as the case may be. In addition, the Company must deliver an Officers’ Certificate and an opinion
of counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

 [REVERSE SIDE OF NOTE] 

GULFMARK OFFSHORE, INC. 
 6.375% Senior Notes due 2022 
 Capitalized terms used herein shall have the
meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 1. Interest. GulfMark
Offshore, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 6.375% per annum, from March 12, 2012 until maturity; [provided that, if a Registration
Default (as defined in the Registration Rights Agreement) occurs, additional interest (the “Additional Interest”) will accrue on this Note to the extent and in the amount provided for in Section 6(a) of the Registration Rights
Agreement.]1 

The Company will pay interest semi-annually in arrears on March 15 and September 15 of each year (each an “Interest
Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further,
that the first Interest Payment Date shall be September 15, 2012. The Company shall pay interest (including post-petition interest in any proceeding under the Bankruptcy Code) on overdue principal and premium, if any, from time to time on
demand at the rate borne on the Notes; it shall pay interest (including post-petition interest in any proceeding under the Bankruptcy Code) on overdue installments of interest (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered
Holders of Notes at the close of business on the March 1 or September 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in the
Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company,
payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and

  
  

	1 	Insert in (i) any initial note and (ii) any Exchange Security or Private Exchange Security, if at the date of issuance of the Exchange Security or Private
Exchange Security (as the case may be), any Registration Default has occurred with respect to the related Initial Securities during the interest period in which such date of issuance occurs. 


  
 A-4








 
interest, premium, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be
in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. If any payment date with respect to the Notes is a Legal Holiday at a place of payment, payment may be made
at that place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. 

3. Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying
Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 
 4. Indenture. The Company issued the Notes under an Indenture dated as of March 12, 2012 (“Indenture”) between the Company and the Trustee. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Section 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the
Company initially limited to $300,000,000 in aggregate principal amount; provided that Additional Notes may be issued pursuant to the Indenture and will be part of the same series as the Initial Notes. 

5. Optional Redemption. (a) Except as set forth in subparagraph (b), (c) or (d) of this paragraph 5, the Notes
shall not be redeemable at the Company’s option prior to March 15, 2017. Thereafter, the Notes will be subject to redemption at any time at the option of the Company, in whole or in part on one or more occasions, upon not less than 30 nor
more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon, if any, to the applicable redemption date, if redeemed during the twelve-month period
beginning on March 15 of the years indicated below: 
  

					
	 Year
	  	Percentage	 
	 2017
	  	 	103.188	% 
	 2018
	  	 	102.125	% 
	 2019
	  	 	101.063	% 
	 2020 and thereafter
	  	 	100.000	% 

 (b) Notwithstanding the foregoing, at any time prior to March 15, 2017, the Company may also redeem
all or a part of the Notes on more than one occasions, upon not less than 30 nor more than 60 days prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid
interest to, the date of redemption (the “Redemption Date”).

premium, if any, interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration, redemption or otherwise, and interest on overdue principal, premium, if any, (to the extent
permitted by law) interest on any interest, if any, on the Notes and all other payment Obligations of the Company to the Holders or the Trustee under the Indenture or under the Notes will be promptly paid in full and performed, all in accordance
with the terms thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other payment Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration, redemption or otherwise. Failing payment when so due of any amount so guaranteed or any performance so guaranteed for whatever reason, the
Guarantors will be jointly and severally obligated to pay the same immediately. 

  
 D-1








 The obligations of the Guarantors to the Holders and to the Trustee pursuant to this
Supplemental Indenture and the Indenture are expressly set forth in Article 10 of the Indenture, and reference is hereby made to such Indenture for the precise terms of this Subsidiary Guarantee. The terms of Article 10 of the Indenture are
incorporated herein by reference. This Subsidiary Guarantee is subject to release as and to the extent provided in Section 10.04 of the Indenture. 
 This is a continuing Subsidiary Guarantee and shall remain in full force and effect and shall be binding upon each Guarantor and its respective successors and assigns to the extent set forth in the
Indenture until full and final payment of all of the Company’s Obligations under the Notes and the Indenture and shall inure 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 herein conferred upon that party shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof. This is a
Subsidiary Guarantee of payment and not a guarantee of collection. 
 2. No Recourse Against Others. No past, present or
future director, officer, employee, incorporator, partner, member, shareholder or agent of any Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, any Subsidiary Guarantees, the Indenture
or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities law and it is the view of the Commission that such waiver is against public policy. 

3. New York Law to Govern. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL
INDENTURE. 
 4. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy
shall be an original, but all of them together represent the same agreement. 
 5. Effect of Headings. The Section
headings herein are for convenience only and shall not affect the construction hereof. 
 6. The Trustee. The Trustee
shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the correctness of the recitals of fact contained herein, all of which recitals are made solely
by the Guarantor. 
 7. Notices. Notices to the Guarantor shall be given in the manner set forth in the Indenture to the
Guarantor’s address set forth below.
