 (a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The
Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in denominations of $1,000 and integral multiples thereof. 
 The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company
and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the
provisions of this Indenture shall govern and be controlling. 
 (b) Global Notes. Notes issued in global form will be
substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of
Exhibit A1 hereto (but 

  

 17 

 
without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note
will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of
outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal
amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 
 (c) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and
“Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the
Global Notes that are held by Participants through Euroclear or Clearstream. 
 Section 2.02 Execution and Authentication.

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

 A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the
Note has been authenticated under this Indenture. 
 The Trustee will, upon receipt of a written order of the Company signed by at least one
Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes up to the aggregate principal amount stated in paragraph 4 of the Notes. The
aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate

Company.

office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional
paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will
notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its
Subsidiaries may act as Paying Agent or Registrar. 
 The Company initially appoints The Depository Trust Company (“DTC”) to act as
Depositary with respect to the Global Notes.

 The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying Agent for the payment of principal, premium or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may
require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any
bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes. 
 Section 2.05

the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each interest payment date and at such other
times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA § 312(a). 

Section 2.06 Transfer and Exchange. 
 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes if: 
 (1) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that
it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 120 days after the date of such notice from the Depositary; 
 (2) the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive
Notes and delivers a written notice to such effect to the Trustee; or 
 (3) there has occurred and is continuing a Default or
Event of Default with respect to the Notes. 
 Upon the occurrence of either of the preceding events in (1) or (2) above,
Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be
exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c) hereof. 
 (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global
Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in any Global Note may be 

  

 19 

 
transferred to Persons who take delivery thereof in the form of a beneficial interest in a Global Note. No written orders or instructions shall be required
to be delivered to the Registrar to effect the transfers described in this Section 2.06(b). 
 (c) Transfer and Exchange
of Beneficial Interests for Definitive Notes. If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof
in the form of a Definitive Note, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.06(g) hereof, and the Company will execute and the Trustee will authenticate
and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.06(c) will be registered in such name or
names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. 
 (d) Transfer and Exchange of Definitive Notes for Beneficial Interests. A Holder of a Definitive Note may exchange such Note for a
beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee
will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes. If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to this
paragraph at a time when a Global Note has not yet been issued, the Company will issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee will authenticate one or more Global Notes in an aggregate
principal amount equal to the principal amount of Definitive Notes so transferred. 
 (e) Transfer and Exchange of Definitive
Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 2.06(e), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such
registration of transfer or exchange, the requesting Holder must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such
Holder or by its attorney, duly authorized in writing. 
 (f) Legends. Each Global Note will bear a legend in substantially
the following form: 
 “THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN
CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE INDENTURE,

HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.” 
 (g) Cancellation and/or Adjustment of Global Notes. At such time
as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained
and canceled by the Trustee in accordance with Section 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 will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at
the direction of the Trustee to reflect such reduction; and 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 will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (h) General Provisions Relating to Transfers and Exchanges. 
 (1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and
Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 
 (2) No service charge will 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, 3.09, 4.10,
4.15 and 9.05 hereof). 
 (3) The Registrar will 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. 
 (4) All Global Notes
and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the
Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (5) 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;

 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 will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required
by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of
them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 
 Every replacement Note is an
additional obligation of the Company and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 
 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; however, Notes held by the Company or a Subsidiary of the Company shall not
be deemed to be outstanding for purposes of Section 3.07(a) hereof. 
 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 will be deemed to be no longer outstanding and will 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, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee
will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned will 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, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but
may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange
for temporary Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 
  

 22 

 Section 2.11 Cancellation.

surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of such canceled Notes

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 will notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less

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 Securities 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 Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any
defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 ARTICLE III

 The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for
partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed
or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for
redemption or purchase also apply to portions of Notes called for redemption or purchase. 
 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
will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the

 (4) the name and address of the Paying Agent; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

called for redemption are being redeemed; and 
 (8) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Notes. 
 At the Company’s request, the Trustee will give the notice of
redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the redemption date, 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

 Section 3.05 Deposit of Redemption or Purchase Price. 
 One Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent prior to 10:00 AM Eastern
Time money sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or
the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest on, all Notes to be redeemed or purchased. 
 If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on
the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to
the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply
with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate
provided in the Notes and in Section 4.01 hereof. 
 Section 3.06 Notes Redeemed or Purchased in Part. 
 Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will
authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Notes issued under this Indenture (including Additional Notes, if any) at a redemption price of     % of the principal amount, plus accrued and unpaid interest to the redemption date, with the net cash proceeds of one or more
Public Equity Offerings of the Company; provided that: 
 (1) at least     % of the aggregate principal
amount of Notes originally issued under this Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 
 (2) the redemption occurs within 90 days of the date of the closing of such Public Equity Offering. 
 (b) Except pursuant to Sections 3.07(a), the Notes will not be redeemable at the Company’s option prior to

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 on the Notes redeemed, to the applicable redemption date, if redeemed
during the twelve-month period beginning on                      of the years indicated below, subject to the rights of Holders of Notes on the
relevant record date to receive interest on the relevant interest payment date: 
  

				
	 Year

	 20    
	  	            	%
	 20     and thereafter
	  	100.000	%

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue
on the Notes or portions thereof called for redemption on the applicable redemption date. 
 (d) 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. 
 The Company is not 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 is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures specified below.

 The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and
not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the
Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other
Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
 If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the
close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to
enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state: 
 (1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open; 
 (2) the Offer Amount, the purchase price and the Purchase Date; 
 (3) that any Note not tendered or accepted for payment will continue to accrue interest; 
 (4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to
accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer
may elect to have Notes purchased in integral multiples of $1,000 only; 
 (6) that Holders electing to have Notes purchased
pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if
appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date; 
 (7) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a 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; 
 (8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer
Amount, the Company will select the Notes and other pari passu 

  

 26 

 
Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such
adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or integral multiples thereof, will be purchased); and 
 (9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered (or transferred by book-entry transfer). 
 On or before the Purchase Date, the Company will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the 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, and will deliver or
cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09.
The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes
tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will 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 will publicly
announce the results of the Asset Sale Offer on the Purchase Date. 
 Other than as specifically provided in this Section 3.09, any
purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

 COVENANTS 
 Section 4.01 Payment of Notes. 
 The Company will 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 will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 10:00
a.m. Eastern Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. 
 The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without
regard to any applicable grace period) at the same rate to the extent lawful. 
 Section 4.02 Maintenance of Office or Agency.

 The Company will maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or
an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with
the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 
 The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; 

  

 27 

 
provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, the City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
 The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03
hereof. 
 Section 4.03 Reports.

within the time periods specified in the SEC’s rules and regulations: 
 (1) all quarterly and annual reports that would
be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file reports, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the
annual information only, a report thereon by the Company’s certified independent registered public accounting firm; and 
 (2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports. 
 In addition, the Company will file a copy of each of the reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the rules and regulations applicable to such
reports (unless the SEC will not accept such a filing) and will post the reports on its website within those time periods. The Company will at all times comply with TIA § 314(a). 
 If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company will
nevertheless continue filing the reports specified in the preceding paragraph with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company will not take any action for the purpose of causing the SEC
not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraph on its website within the time periods
that would apply if the Company were required to file those reports with the SEC. 
 (b) If the Company has designated any of
its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by paragraph (a) of this Section 4.03 will include a reasonably detailed presentation, either on the face of the financial
statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate
from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

any Notes remain outstanding, if at any time they are not required to file with the SEC the reports required by paragraphs (a) and (b) of this Section 4.03, the Company will furnish to the Holders and to securities analysts and
prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 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

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 has occurred, describing all such Defaults or Events
of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments
on account of the principal of or interest, if any, 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) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end
financial statements delivered pursuant to Section 4.03 above shall be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of established national reputation) that in making the
examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation. 
 (c) So long as any of the Notes are outstanding, the Company will deliver to the Trustee, forthwith (and in any event within 10 days) 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 will
pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment
is not adverse in any material respect to the Holders of the Notes. 
 Section 4.06 Stay, Extension and Usury Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the

Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or
any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company and other than dividends or distributions payable
to the Company or a Restricted Subsidiary of the Company); 
  

 29 

 (2) purchase, redeem or otherwise acquire or retire for value (including without

Stated Maturity thereof; or 
 (4) make any Restricted Investment (all such payments and other actions set forth in these
clauses (1) through (4) being collectively referred to as “Restricted Payments”),

such Restricted Payment, no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment and:

four most recent fiscal quarters for which internal financial statements are available is less than 1.6 to 1, such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted
Subsidiaries since the beginning of the fiscal quarter in which such Restricted Payment is made (such Restricted Payments for purposes of this clause (2) meaning only distributions on the Company’s common stock), is less than the sum,
without duplication, of: 
 (a) $             million less the
aggregate amount of all Restricted Payments made by the Company pursuant to this clause (2)(a) during the period ending on the last day of the fiscal quarter of the Company immediately preceding the fiscal quarter in which such Restricted

of this Indenture (provided that the amount of such cash proceeds used for any such 

  

 31

completed substantially contemporaneously with the repurchase and, in respect of any Senior Subordinated Notes, incurred pursuant to Section 4.09(b)(19) hereof, provided that such transactions may only be consummated in accordance with the
Securities Holders Agreement, provided, further, that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from Section 4.07(1)(b) hereof.] 
 (c) If the Company’s Net Cash Balance is less than $             million
at the end of any fiscal year beginning with the fiscal year ended January 1, 20    , then until the earlier of (a) the first fiscal year end thereafter at which the Company’s Net Cash Balance equals or exceeds
$             million and (b) the first fiscal quarter end thereafter at which the Company’s Net Cash Balance equals or exceeds
$             million, the amount of Excess Cash that the Company may use to make dividends or other distributions on its common stock pursuant to the second clause (1) of the first
paragraph of this covenant shall be reduced to 98.0% thereof.

cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The
Fair Market Value of any assets or securities that are required to be valued by Section 4.07 will be determined by the Board of Directors of the Company whose resolution with respect thereto will be delivered to the Trustee to the extent that
such Fair Market Value exceeds $             million. For purposes of determining compliance with Section 4.07, in the event that a Restricted Payment meets the criteria of more than
one of the exceptions described in Section 4.07(b) or is entitled to be made pursuant to Section 4.07(a) hereof, the Company will be permitted, in its sole discretion, to classify the Restricted Payment in any manner that complies with

 Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or
become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) pay
dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company
or any of its Restricted Subsidiaries; 
 (2) make loans or advances to the Company or any of its Restricted Subsidiaries; or

 (3) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries. 
 (b) However, the preceding restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by
reason of: 
 (1) agreements governing Existing Indebtedness and any other agreement, including Credit Facilities and the
Subordinated Note Indenture as in effect on the date of this Indenture and any amendments, restatements, modifications, renewals, increases, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments,
restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements
on the date of this Indenture; 
 (2) this Indenture and the Notes; 
 (3) applicable law, rule, regulation or order; 
 (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in
effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the
properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; 

(5) customary non-assignment provisions in contracts, licenses and other commercial agreements entered into in the ordinary course of
business; 
 (6) purchase money obligations for property acquired in the ordinary course of business and Capital Lease
Obligations that impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 4.08(a) hereof; 
 (7) any agreement for the sale or other disposition of all or substantially all of the Capitol Stock of assets of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending the sale or
other disposition; 
  

 33 

 (8) Permitted Refinancing Indebtedness; provided that the encumbrances or restrictions
contained in the agreements governing such Permitted Refinancing Indebtedness are, in the good faith judgment of the senior management or Board of Directors of the Company, not materially more restrictive, taken as a whole, than those contained in
the agreements governing the Indebtedness being refinanced; 
 (9) Any restriction on the transfer of assets under any Lien
permitted under this Indenture imposed by the holder of the Lien; 
 (10) provisions limiting the disposition or distribution
of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business or with the approval of the Company’s Board
of Directors, which limitation is applicable only to the assets that are the subject of such agreements; and 
 (11)
restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. 
 Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock. 
 (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”)
any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur
Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding
the date on which such additional Indebtedness is incurred or such Disqualified Stock or such preferred stock is issued, as the case may be, would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the
net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period. 
 (b) The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness
(collectively, “Permitted Debt”): 
 (1) the incurrence by the Company and any of its Restricted Subsidiaries of
additional Indebtedness and letters of credit under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum
potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (x) $             million and (y) the amount of the Borrowing Base as
of the date of such incurrence; 
 (2) the incurrence by the Company and its Restricted Subsidiaries of the Existing
Indebtedness; 
 (3) the incurrence by the Company of Indebtedness represented by the Notes to be issued on the date of this
Indenture; 
 (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital
Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or
equipment used in the business of the Company or any of its Restricted Subsidiaries (whether through the direct purchase of assets or the Equity Interests of any Person owning such assets), in an aggregate principal amount, including all Permitted
Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (5), not to exceed $20.0 million at any time outstanding; 
  

 34 

 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted
Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred by
Section 4.09(a) or clauses (2), (3), (4), (5), (6), (17) or (18) of this Section 4.09(b); 
 (6) the
incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that: 
 (a) if the Company is the obligor on such Indebtedness and the payee is not the Company, such Indebtedness must be expressly subordinated
to the prior payment in full in cash of all Obligations then due with respect to the Notes; and 
 (b)(i) any subsequent
issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that
is not either the Company or a Restricted Subsidiary of the Company, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this
clause (7); 
 (7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its
Restricted Subsidiaries of shares of preferred stock; provided, however, that: 
 (a) any subsequent issuance or transfer of
Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and 
 (b) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary of the Company, 
 will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (8); 
 (8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business;

 (9) the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a Restricted
Subsidiary of the Company that was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Guarantee shall be subordinated
or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (10) the incurrence by the Company or any
of its Restricted Subsidiaries of Indebtedness in respect of bankers’ acceptances, performance, bid and surety bonds and completion guarantees provided in the ordinary course of business; 
 (11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other
financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds in the ordinary course of business; 
 (12) the incurrence of Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case,
incurred in connection with the disposition of any business, assets or a Restricted Subsidiary, other than the Guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or a Restricted Subsidiary for the
purpose of financing such acquisition; provided, however, that: 
 (a) such Indebtedness is not reflected on the balance
sheet of the Company or any Restricted Subsidiary (contingent obligations referred to in a footnote to financial statements and not 

  

 35 

 
otherwise reflected on the balance sheet will not be deemed to be reflected on such balance sheet for purposes of this clause (a)); and 
 (b) the maximum assumable liability in respect of all such Indebtedness shall at no time exceed the gross proceeds including non-cash
proceeds (the Fair Market Value of such non-cash proceeds being measured at the time received and without giving effect to any subsequent changes in value) actually received by the Company and Restricted Subsidiaries in connection with such
disposition; 
 (13) the incurrence of Indebtedness owed to any Person in connection with worker’s compensation,
self-insurance, health, disability or other employee benefits or property, casualty or liability insurance provided by such Person to the Company or any of its Restricted Subsidiaries, pursuant to reimbursement or indemnification obligations to such
Person, in each case incurred in the ordinary course of business and consistent with past practices; 
 (14) pledges, deposits
or payments made or given in the ordinary course of business in connection with or to secure statutory, regulatory or similar obligations, including obligations under health, safety or environmental obligations, or arising from guarantees to
suppliers, lessors, licenses, contractors, franchisees or customers of obligations, other than Indebtedness, made in the ordinary course of business; 
 (15) the incurrence of Indebtedness by the Company or any of its Restricted Subsidiaries issued to directors, officers or employees of the Company or any of its Restricted Subsidiaries in connection with the
redemption or purchase of Capital Stock that, by its terms, is subordinated to the Notes, is not secured by any assets of the Company or any of its Restricted Subsidiaries and does not require cash payments prior to the Stated Maturity of the Notes,
in an aggregate principal amount at any time outstanding not to exceed $             million; 
 (16) the incurrence of Indebtedness by the Company or any Restricted Subsidiary to finance the acquisition (including, without limitation, by way of a merger) of Capital Stock of any Person engaged in, or assets used
or useful in, a Permitted Business; provided that the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such
Indebtedness is incurred would have been at least 1.75 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the Indebtedness had been incurred at the beginning of such four-quarter period;
and 
 (17) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate
principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (18),
not to exceed $20.0 million; and 
 (18) the issuance of our common stock, provided that (a) no Default or Event of
Default has occurred and is continuing at the time of such issuance or would be caused thereby, (b) the Company uses the proceeds of such issuance solely to repurchase shares of common stock issued on or before the date hereeof from holders
thereof in accordance with the [Securities Holders Agreement]. 
 The Company will not incur any Indebtedness (including Permitted Debt) that
is contractually subordinated in right of payment to any other Indebtedness of the Company unless such Indebtedness is also contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no
Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis. 
 For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than
one of the categories of Permitted Debt described in clauses 

  

 36 

 
(1) through (19) above or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to classify such item
of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the date on which Notes
are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest, the accretion
or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class
of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the
Company as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded
solely as a result of fluctuations in exchange rates or currency values. 
 The amount of any Indebtedness outstanding as of any date will
be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

 (2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 
 (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 
 (A) the Fair Market Value of such assets at the date of determination; and 
 (B) the amount of the Indebtedness of the other Person. 
 Section 4.10 Asset Sales. 
 The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may be)
receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
 (2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or
Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: 
 (A) any liabilities, as
shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes) 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 within 180 days
after such Asset Sale, to the extent of the cash received in that conversion; and 
 (C) any stock or assets of the kind
referred to in clauses (2) or (4) of the next paragraph of this Section 4.10. 
 Any Asset Sale pursuant to a condemnation,
appropriation or other similar taking, including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a Permitted Lien or exercise by the related lienholder of rights with respect to any of the foregoing, including
by deed or assignment in lieu of 

  

 37 

 
foreclosure, will not be required to satisfy the conditions set forth in the preceding paragraph. Within 360 days after the receipt of any Net Proceeds from
an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds, at its option: 
 (1) to repay, prepay or purchase Indebtedness and other Obligations under a Credit Facility and, if the Indebtedness repaid is revolving credit Indebtedness to correspondingly reduce commitments with respect thereto; 
 (2) to acquire all or substantially all of the assets of another Permitted Business, or to acquire any Capital Stock of another Permitted
Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Company; 
 (3) to make a capital expenditure; 
 (4) to acquire other assets that are not classified as
current assets under GAAP and that are used or useful in a Permitted Business; or 
 (5) any combination of the foregoing
clauses (1) through (4). 
 In the case of clauses (2) and (4) above, the Company will be deemed to have complied with its
obligations in the preceding paragraph if it enters into a binding commitment to acquire such assets or Capital Stock prior to 360 days after the receipt of the applicable Net Proceeds; provided that such binding commitment will be subject only to
customary conditions and such acquisition is completed within 180 days following the expiration of the aforementioned 360 day period. If the acquisition contemplated by such binding commitment is not consummated on or before such 180th day, and the
Company has not applied the applicable Net Proceeds for another purpose permitted by the preceding paragraph on or before such 180th day, such commitment shall be deemed not have been a permitted application of Net Proceeds. Pending the final
application of any Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the 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 second paragraph of this Section 4.10 will constitute
“Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $             million, within 30 days thereof, the Company will make an Asset Sale Offer to all Holders of
Notes and all Holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the
maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest to the
date of purchase and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal
amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 Any Asset Sale Offer will be made in compliance
with all applicable laws, rules and regulations, including, if applicable, Regulation 14E under the Exchange Act and the rules thereunder and all other applicable Federal and state securities laws. To the extent that the provisions of any securities
laws or regulations conflict with the provisions of this Section 4.10, the Company’s compliance with those laws and regulations will not in and of itself cause a breach of its obligations under this Section 4.10. 
 Section 4.11 Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, on or after the date of this Indenture, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties
or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, 

  

 38 

 
contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate
Transaction”), unless: 
 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the
relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company; and 
 (2) The Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $            
million, a resolution of the Board of Directors of the Company set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with this Section 4.11(a) and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Board of Directors of the Company or, if none, a disinterested representative appointed by the Board of Directors for such purpose; and 
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$             million, an opinion as to the fairness to the Company or such Subsidiary of such Affiliate Transaction from a financial point of view or that such Affiliate Transaction is not
less favorable to the Company and its Restricted Subsidiaries than could reasonably be expected to be obtained in a comparable transaction with a Person that is not an Affiliate of the Company, as issued by an accounting, appraisal or investment
banking firm of national standing. 
 (b) The following items will not be deemed to be Affiliate Transactions and, therefore,
will not be subject to the provisions of Section 4.11(a) hereof: 
 (1) any employment agreement, officer or director
indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto; 
 (2) transactions between or among the Company and/or its Restricted Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because
the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 
 (4) fees
and compensation paid to officers and employees of the Company or any Restricted Subsidiaries, to the extent such fees and compensation are reasonable and customary, and payment of reasonable directors’ fees to Persons who are not otherwise
Affiliates of the Company; 
 (5) any issuance or sale of Equity Interests (other than Disqualified Stock) of the Company to
Affiliates, employees, officers and directors of the Company or any of its Restricted Subsidiaries; 
 (6) Restricted Payments
that are permitted by Section 4.07 hereof; 
 (7) maintenance in the ordinary course of business of customary benefit
programs or arrangements for employees, officers or directors, including vacation plans, health and life insurance plans, deferred compensation plans and retirement or savings plans and similar plans; 
 (8) loans or advances to employees in the ordinary course of business not to exceed
$             million in the aggregate at any one time outstanding; 
 (9) any agreement as in effect and entered into as of the date of this Indenture, including the [Securities Holders Agreement], or any amendment thereto or any transaction contemplated thereby (including pursuant to any amendment thereto)
in any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders of the Notes in any material respect than the original agreement as in effect on the date of this Indenture;

  

 39 

 (10) any transaction or series of transactions between the Company or any Restricted
Subsidiary and any of their Joint Ventures; provided that (a) such transaction or series of transactions is in the ordinary course of business between the Company or such Restricted Subsidiary and such Joint Venture and (b) with respect to
any such Affiliate Transaction involving aggregate consideration in excess of $5.0 million, such Affiliate Transaction complies with Section 4.11(a)(1) hereof and such Affiliate Transaction has been approved by the Board of Directors of the
Company; 
 (11) any service, purchase, lease, supply or similar agreement entered into in the ordinary course of business
between the Company or any Restricted Subsidiary and any Affiliate that is a customer, client, supplier or purchaser or seller of goods or services, so long as the senior management or Board of Directors of the Company determines in good faith that
any such agreement is on terms no less favorable to the Company or such Restricted Subsidiary than those that could be obtained in a comparable arms’-length transaction with an entity that is not an Affiliate; and 
 (12) the payment of all fees and expenses related to the Transactions. 
 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 of any kind (other than Permitted Liens) to secure Indebtedness of any kind on any asset now owned or hereafter
acquired, unless all payments due under this Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured (or, if such obligations are subordinated by their terms to the Notes, prior to the obligations so
secured) until such time as such obligations are no longer secured by a Lien. 
 Section 4.13 Business Activities. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such
extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole, as reasonably determined in good faith by the Board of Directors of the Company. 
 Section 4.14 Corporate Existence. 
 Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect: 
 (1) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of
the Company or any such Subsidiary; and 
 (2) the rights (charter and statutory), licenses and franchises of the Company and
its 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 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 Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 
 Section 4.15 Offer to Repurchase Upon Change of Control. 
 (a) If a Change of Control occurs, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple of $1,000) of that Holder’s Notes pursuant to a Change of Control Offer on the terms set forth herein. In the Change of Control Offer (subject to the conditions required by applicable law, if any), the Company
will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased to the date of purchase, subject to the rights of Holders of Notes on the
relevant 

  

 40 

 
record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). No earlier than ten days and no later
than 20 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 
 (1) 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; 
 (2) 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”); 
 (3) that any Note not tendered will
continue to accrue interest; 
 (4) that, unless the Company defaults in the payment of the Change of Control Payment, all
Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to
the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 
 (6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the
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 
 (7) that Holders whose Notes are being purchased only in part
will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. 
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent
those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Sections 3.09 or
4.15 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.15 by virtue of such compliance. 
 (b) On the Change of Control Payment Date, the Company will, to the extent lawful: 
 (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 The Paying
Agent will promptly mail (but in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly 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. 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. 
  

 41 

 Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to
make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in Section 4.15 and Section 3.09
hereof and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the
applicable redemption price. 
 Section 4.16 Intentionally Left Blank. 
 Section 4.17 Limitation on Sale and Leaseback Transactions. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Company may enter into a sale and leaseback transaction if: 

(1) the Company could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and
leaseback transaction under the Fixed Charge Coverage Ratio test in Section 4.09(a) hereof and (b) incurred a Lien to secure such Indebtedness pursuant to the provisions of Section 4.12 hereof; 
 (2) the gross cash proceeds of that sale and leaseback transaction are at least equal to the Fair Market Value of the property that is the
subject of that sale and leaseback transaction; and 
 (3) the transfer of assets in that sale and leaseback transaction is
permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.10 hereof. 
 Section 4.18
Payments for Consent. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay
or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to
be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.19 Intentionally Left Blank. 
 Section 4.20 Designation of Restricted and Unrestricted Subsidiaries. 
 The Board of Directors of the Company may designate
any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by
the Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07
hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets
the definition of an Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default. 
 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy
of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any
Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to
be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in default of such covenant. The Board of Directors
of the 

  

 42 

 
Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an
incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09
hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.

with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of
a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof.

 (B) results in the acceleration of such Indebtedness prior to its express maturity, 
 and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment

Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without
further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

 Upon any such declaration, the Notes shall become due and payable immediately. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of
the acceleration) have been cured or waived. 
  

 45 

 If an Event of Default occurs on or after
                    , 20     by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company
with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Notes pursuant to Section 3.07 hereof, then, upon acceleration of the Notes, an equivalent premium shall
also become and be immediately due and payable, to the extent permitted by law, anything in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default occurs prior to
                    , 20     by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company
with the intention of avoiding the prohibition on redemption of the Notes prior to such date, then, upon acceleration of the Notes, an additional premium shall also become and be immediately due and payable, to the extent permitted by law, in an
amount, for each of the years beginning on                      of the years set forth below, as set forth below (expressed as a percentage of the
principal amount of the Notes on the date of payment that would otherwise be due but for the provisions of this sentence): 
  

				
	 Year
	  	Percentage	 
	 20    
	  	    	%
	 20    
	  	    	%

	  	    	%

 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, premium and 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. 
 Holders of not less than a majority in aggregate principal amount of the then
outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal
of, premium or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its
consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of
this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
 Section 6.05 Control by Majority. 
 Holders of a majority in aggregate principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture that the Trustee determines in good faith may be 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 may pursue a remedy with respect to this Indenture or the Notes only if: 
 (1) such Holder gives to the
Trustee written notice that an Event of Default is continuing; 
  

 46 

 (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes
make a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders offer and, if requested, provide to
the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; 
 (4) the
Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 
 A Holder 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. 
 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(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount
as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 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 6, 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, expenses and
liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
  

 47 

 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. 
 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 costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys’ fees and expenses against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a
suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes. 
 ARTICLE VII 
 TRUSTEE 
 Section 7.01 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a

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

they conform to the requirements of this Indenture.

negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this paragraph does not
limit the effect of paragraph (b) of this Section 7.01;

judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

 48 

 (e) No provision of this Indenture will require the Trustee to expend or risk its own

require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may

reliance thereon.

 (f) The Trustee will 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 have offered to the Trustee reasonable indemnity or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or
direction. 
 (g) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or
damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; 
 (h) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has

 (i) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be

 Section 7.03 Individual Rights of Trustee. 
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the 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 SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) 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. 
  

 49 

 Section 7.04 Trustee’s Disclaimer. 
 The Trustee will 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 will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to 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 known to the Trustee, the Trustee will 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 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. 
 (a) 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 will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a)
(but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail all
reports as required by TIA § 313(c). 
 (b) A copy of each report at the time of its mailing to the Holders of Notes will
be mailed by the Trustee to the Company and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the Notes are listed on any
stock exchange. 
 Section 7.07 Compensation and Indemnity. 
 (a) The Company will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services
hereunder as the parties shall agree in writing from time to time. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all
reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

 (b) The Company will indemnify the Trustee against any and all losses, liabilities, claims, damages or expenses 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 a (including this Section 7.07) and defending itself
against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be
attributable to its negligence or bad faith. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company of its obligations hereunder. The
Company will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without
its consent, which consent will not be unreasonably withheld. 
 (c) The obligations of the Company under this
Section 7.07 will survive the satisfaction and discharge of this Indenture. 
  

 50 

 (d) To secure the Company’s payment obligations in this Section 7.07, the
Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and discharge of this
Indenture. 
 (e) When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.01(8) or (9) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable. 
 Section 7.08 Replacement of Trustee. 
 (a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

 (b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the

 ARTICLE VIII 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may at any time, at the option of its
Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, 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 will, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means
that the Company will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which will 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 clauses (1) and (2) below, and to have satisfied all their 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 will survive until otherwise terminated or discharged hereunder: 
 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium on, such Notes when such payments are due from the trust referred to in Section 8.04
hereof; 
 (2) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in
connection therewith; and 
 (4) 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 will, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released from each 

  

 52 

 
of their obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 hereof and
clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter
be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding”
for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply
with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any
such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and
such Notes will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, Sections 6.01(3) through 6.01(6) hereof will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant
Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:

 (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or independent registered public accounting firm, to pay the principal
of, premium and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or
to a particular redemption date; 
 (2) in the case of an election under Section 8.02 hereof, the Company must deliver to
the Trustee an Opinion of Counsel 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; 
 (3) in the case of an election under Section 8.03 hereof, the Company must
deliver to the Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and
the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company is a party or by which the Company is bound; 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
  

 53 

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

 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 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 will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (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 and interest, but such money need not be segregated from other funds except to the extent required by
law. 
 The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or
non-callable Government Securities deposited pursuant to Section 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. 
 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to
time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 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(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or
Covenant Defeasance. 
 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, premium or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the
Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will
thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to
the Company. 
 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, then the Company’s obligations under this Indenture and the Notes will 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 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the 

  

 54 

 
Company makes any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Company will 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 IX 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 
 Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of Note: 
 (1) to cure any ambiguity, defect or inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
 (3) to provide for the assumption of the Company’s obligations to the Holders of the Notes by a successor to the Company pursuant to
Article 5 hereof; 
 (4) 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 Holder; 
 (5) to comply with requirements of the SEC in
order to effect or maintain the qualification of this Indenture under the TIA; 
 (6) to conform the text of this Indenture,
or the Notes to any provision of the “Description of Notes” section of the Company’s prospectus dated             , 20     , relating to the initial
offering of the Notes, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture or the Notes; 
 (7) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture; 
 (8) to comply with the provisions of DTC or the Trustee with respect to the provisions of this Indenture and the Notes relating to
transfers and exchanges of Notes or beneficial in the Notes; or 
 Upon the request of the Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will 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 will not be obligated to enter into such amended or
supplemental indenture that affects its own rights, duties 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, without limitation, Section 3.09, 4.10 and 4.15 hereof) and the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation,
Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 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 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 aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class
(including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of
this Section 9.02. 
  

 55 

 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the
execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee will join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 
 It is 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, supplement or waiver, but it is sufficient if such consent approves
the substance thereof. 
 After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will 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, will 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 voting as a single class 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, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

 (1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed maturity of any Note or alter or waive 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); 
 (3) reduce the rate
of or change the time for payment of interest, including default interest, on any Note; 
 (4) waive a Default or Event of
Default in the payment of principal of, or premium, if any, 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); 
 (5) make any Note payable in money other than that stated in the
Notes; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of
Holders of Notes to receive payments of principal of, or interest or premium on, the Notes; 
 (7) waive a redemption payment
with respect to any Note (other than a payment required by Sections 3.09, 4.10 or 4.15 hereof); 
 (8) amend the covenant
described in Section 4.07 in any way that would permit the Company to take any action described in clauses (1) or (2) of the first paragraph of such covenant when it would not have otherwise been permitted to take such action under
the terms of such covenant as in effect on the date of the indenture; or 
 (9) make any change in the preceding amendment,
supplement and waiver provisions that requires each holder’s consent. 
 Section 9.03 Compliance with Trust Indenture Act.

 Every amendment or supplement to this Indenture or the Notes will be set forth in a amended or supplemental indenture that complies with
the TIA as then in effect. 
  

 56 

 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 amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder. 
 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, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 
 Section 9.06 Trustee to Sign Amendments, etc. 
 The Trustee will 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 Company may not sign an amended or supplemental indenture until the Board of Directors of the Company approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01
hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

(1) either:

delivered to the Trustee for cancellation; or 
 (b) all Notes that have not been delivered to the Trustee for cancellation
have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust
solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire
Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; 
  

 57 

 (2) no Default or Event of Default has occurred and is continuing on the date of such

the Company is a party or by which the Company is bound; 
 (3) the Company has paid or caused to be paid all sums payable by

survive the satisfaction and discharge of this Indenture. 
 Section 11.02 Application of Trust Money. 
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust
and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.
