credit or similar arrangement, the amount thereof shall be deemed to be the average daily balance of such Indebtedness during such four-fiscal-quarter period); 
 (2) if since the beginning of such period the Issuer or any Restricted Subsidiary shall have Transferred any assets in an
Asset Sale, the EBITDA for such period shall be reduced by an amount equal to the EBITDA (if positive) directly attributable to the assets which are the subject of such Transfer for such period, or increased by an amount equal to the EBITDA (if

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 Issuer signed by two Officers (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 plus Notes issued to pay Special Interest pursuant to paragraph 2 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 Issuer 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 Issuer to authenticate Notes. An authenticating agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the
Issuer. 
 Section 2.03 Registrar and Paying Agent. 
 The Issuer will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented
for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuer 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 Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in
writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as
Paying Agent or Registrar.

 The Issuer initially appoints The Depository Trust Company (“DTC”) to act
as Depositary with respect to the Global Notes. 
 The Issuer initially appoints the Trustee to act as the Registrar and Paying
Agent and to act as Custodian with respect to the Global Notes. 
 Section 2.04 Paying Agent to Hold Money in Trust. 
 The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit
of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest or Special Interest, if any, on, the Notes, and will notify the Trustee of any default by the Issuer 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 Issuer 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 Issuer or a Subsidiary) will have no further liability for the money. If the Issuer 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 Issuer, the Trustee will serve as Paying Agent for the Notes. 
 Section 2.05 Holder Lists. 
 The Trustee will preserve in as current a form
as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA §312(a). If the Trustee is not the Registrar, the Issuer will furnish to the Trustee at least five
Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the
Issuer 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 Issuer for Definitive Notes if: 
 (1) the Issuer 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 Issuer within 120 days after
the date of such notice from the Depositary; 
 (2) the Issuer 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

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. 
 (i) General Provisions Relating to Transfers and Exchanges. 
 (1) To permit registrations of transfers and exchanges, the Issuer 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 Issuer 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). 
  

 39 








 (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 Issuer, 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 Issuer 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 mailing of any notice of redemption under Section 3.02 hereof and ending at the close of business on the
day of such mailing; 
 (B) to register the transfer of or to exchange any Note selected for redemption in whole
or in part, except the unredeemed portion of any Note being redeemed in part; or 
 (C) to register the transfer
of or to exchange a Note between a record date and the next succeeding interest payment date. 
 (6) Prior to due
presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal
of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to the contrary. 
 (7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 
 (8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this
Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 
 (9) The
Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any
transfers between or among Depositary Participants or beneficial owners of interests in any Global Notes) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 (10) Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary.

 Section 2.07 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction,
loss or theft of any Note, the Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is
sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in replacing
a Note. 
 Every replacement Note is an additional obligation of the Issuer 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 Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer 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 Issuer, 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 Issuer or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any Guarantor, will be considered as though not outstanding, except that for the
purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that 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 Issuer 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 Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer will prepare and the Trustee will authenticate definitive
Notes in exchange for temporary Notes. 
  

 41 








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

 Section 2.11 Cancellation. 
 The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of such cancelled Notes in accordance with its then customary procedures. The Issuer
may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 
 Section 2.12
Defaulted Interest. 
 If the Issuer defaults in a payment of interest on the Notes, it will pay the defaulted interest in
any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer
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 Issuer will fix or cause to be fixed each such special record date and payment date; provided
that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name
and at the expense of the Issuer) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 Section 2.13 CUSIP Numbers. 
 The Issuer in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 ARTICLE 3 
 REDEMPTION AND PREPAYMENT 
 Section 3.01 Notices to Trustee. 
 If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the
Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers’ Certificate setting forth: 
 (1) the clause of this Indenture pursuant to which the redemption shall occur; 
  

 42 








 (2) the redemption date; 
 (3) the principal amount of Notes to be redeemed; and 
 (4) the redemption price. 
 Section 3.02 Selection of Notes to Be Redeemed or Purchased. 
 If less than all of the Notes are to be redeemed
or purchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2 hereof, based on a method that most nearly
approximates a pro rata selection as the Trustee deems fair and appropriate) unless otherwise required by law or applicable stock exchange or depositary requirements. 
 In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise
provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase. 
 The Trustee will promptly notify the Issuer 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 $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes
of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of 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 Issuer will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption
date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 hereof. 
 The notice will identify the Notes to be redeemed (including CUSIP number(s)) and will state: 
 (1) the redemption date; 
 (2) the redemption price; 
 (3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after
the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 
 (4) the name and address of the Paying Agent; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
  

 43 








 (6) that, unless the Issuer defaults in making such redemption payment,
interest on Notes called for redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph
of the Notes and/or Section of this Indenture pursuant to which the Notes 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 Issuer’s request, the Trustee will give the notice of redemption in the Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least
45 days prior to the redemption date, or such shorter period as to which the Trustee shall have consented in its sole discretion, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be
stated in such notice as provided in the preceding paragraph. 
 Section 3.04 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and
payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 
 Section 3.05 Deposit of Redemption
or Purchase Price. 
 Prior to the redemption or purchase date, the Issuer will deposit with the Trustee or with the Paying
Agent money sufficient to pay the redemption or purchase price of and, accrued interest and Special Interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuer any money
deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of and, accrued interest and Special Interest, if any, on all Notes to be redeemed or purchased. 
 If the Issuer 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 Issuer 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 Issuer will issue and, upon receipt of an Authentication Order, the
Trustee will authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. 
 Section 3.07 Optional Redemption. 
 (a) At any time on or prior to
December 1, 2012 the Issuer may, at its option on any one or more occasions, redeem Notes in an aggregate principal amount not to exceed 35% of the aggregate

  

 44 








 
principal amount of Notes issued under this Indenture at a redemption price of 107.875% of the principal amount, plus accrued and unpaid interest to the redemption date, with the Net Cash
Proceeds of one or more Equity Offerings; provided that: 
 (1) at least 65% of the aggregate principal amount of
Notes issued under this Indenture remains outstanding immediately after the occurrence of such redemption (excluding Notes held by the Issuer and its Subsidiaries); and 
 (2) the redemption occurs within 90 days of the date of the closing of such Equity Offering. 
 (b) At any time prior to December 1, 2014, the Issuer may redeem all or a part of the Notes, upon not less than 30 nor more than 60
days’ prior notice mailed by first-class mail to the registered address of each holder of Notes or otherwise delivered in accordance with the procedures of DTC, at a redemption price equal to 100% of the principal amount of the Notes redeemed
plus the Applicable Premium as of, and accrued and unpaid interest and Special Interest, if any, to the date of redemption (the “Redemption Date”), subject to the rights of the holders of record on the relevant record date to receive
interest due on the relevant interest payment date. 
 (c) Except pursuant to the preceding paragraphs, the Notes will not be
redeemable at the Issuer’s option prior to December 1, 2014. 
 (d) The Notes will be redeemable at the option of the
Issuer, in whole or in part, at any time on or after December 1, 2014 at the redemption prices (expressed as a percentage of principal amount) set forth below, plus accrued and unpaid interest thereon, if any, to the redemption date (subject to
the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve month period beginning on December 1 of the years indicated below:

	 2016
	  	101.313%
	 2017 and thereafter
	  	100.000%

 Unless the Issuer
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. 
 (e) 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 Issuer is not required to make
mandatory redemption or sinking fund payments with respect to the Notes. 
 Section 3.09 Net Proceeds Offer. 
 In the event that, pursuant to Section 4.10 hereof, the Issuer is required to commence Net Proceeds Offer, it will follow the procedures
specified below. 
  

 45 








 The Net Proceeds 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, prepay or redeem with the proceeds of sales of assets. The Net Proceeds 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 Issuer will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata
basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Net Proceeds
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 and Special Interest, if any, 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 Net Proceeds Offer. 
 Upon
the commencement of a Net Proceeds Offer, the Issuer 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 Net Proceeds Offer. The notice, which will govern the terms of the Net Proceeds Offer, will state: 
 (1) that the Net Proceeds Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Net Proceeds 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 Issuer defaults in making such payment, any Note accepted for payment pursuant to the Net Proceeds Offer
will cease to accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note purchased
pursuant to a Net Proceeds Offer may elect to have Notes purchased in denominations of $2,000 or an integral multiple of $1,000 in excess thereof; 
 (6) that Holders electing to have Notes purchased pursuant to any Net Proceeds 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 Issuer, a Depositary, if appointed by the Issuer, 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 Issuer, the Depositary or the Paying Agent, as the case
may be, receives, not later than the expiration of the Offer Period, an electronic 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 Issuer will select the

  

 46 








 
Notes and other pari passu 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 Issuer so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess 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
Issuer 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 Net Proceeds 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 Issuer in accordance
with the terms of this Section 3.09. The Issuer, 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 Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon written request from the Issuer, 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 Issuer to the Holder thereof. The
Issuer will publicly announce the results of the Net Proceeds 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. 
 ARTICLE 4 
 COVENANTS 
 Section 4.01 Payment of Notes. 
 The Issuer will pay or cause to be paid the principal of, premium on, if any, and interest and Special Interest, if any, on, the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest and
Special Interest, if any, will be considered paid on the date due if the Paying Agent, if other than the Issuer or a Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Issuer in immediately available funds
and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due. The Issuer will pay all Special Interest, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights
Agreement. 
 The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and Special Interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Section 4.02
Maintenance of Office or Agency. 
 The Issuer 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

  

 47 








 
Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Issuer will
give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer 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 Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission will in any manner relieve the Issuer of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Issuer will give prompt written
notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
 The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with Section 2.03 hereof. 
 Section 4.03 Reports. 
 (a) Whether or not required by the rules and
regulations of the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Holders of Notes or cause the Trustee to furnish to the Holders of Notes (or file with the SEC for public availability), 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 Issuer were required to file such reports; and 
 (2) all
current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file such reports. 
 The availability of the foregoing materials on the SEC’s EDGAR service (or any successor to the EDGAR service) shall be deemed to satisfy the Issuer’s delivery obligations; provided that the Trustee shall have no responsibility to
verify whether the Issuer has filed such materials. 
 All such reports will be prepared in all material respects in accordance
with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will include a report on the Issuer’s consolidated financial statements by the Issuer’s certified independent public accountants. In
addition, the Issuer 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). 
 If, at any time after consummation of the Exchange Offer contemplated by the
Registration Rights Agreement, the Issuer is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Issuer will nevertheless continue filing the reports specified in the preceding paragraphs with the SEC
within the time periods specified above unless the SEC will not accept such a filing. The Issuer 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 Issuer’s filings for any reason, the Issuer will post the reports referred to in the preceding paragraphs on its website within the time periods that would apply if the Issuer were required to file those reports with the SEC.

Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries separate from the financial condition and results of
operations of the Unrestricted Subsidiaries of the Issuer. 
 (c) Notwithstanding anything herein to the contrary, in the event
that (i) the rules and regulations of the SEC permit the Issuer and Parent, or any other direct or indirect parent company of the Issuer, to report at such parent entity’s level on a consolidated basis and (ii) such parent entity of
the Issuer is not engaged in any business in any material respect other than incidental to its ownership, directly or indirectly, of the Capital Stock of the Issuer, the information and reports required by this covenant may be those of such parent
company on a consolidated basis. 
 (d) For so long as any Notes remain outstanding, if at any time Issuer and Guarantors are
not required to file with the SEC the reports required by paragraphs (a) and (b) of this Section 4.03, the Issuer and the Guarantors 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. 
 (e) Delivery of reports,
information and documents to the Trustee pursuant to this Section 4.03 and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein or determinable from information contained therein,
including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 Section 4.04 Compliance Certificate. 
 (a) The Issuer and each Guarantor (to
the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 120 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Issuer and its Subsidiaries
during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuer has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to
each such Officer signing such certificate, that to the best of his or her knowledge the Issuer 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 Issuer is taking or
proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of, premium on, if any, or interest or Special Interest, if
any, on, the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuer 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 Issuer’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 Issuer 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. 
  

 49 








 (c) So long as any of the Notes are outstanding, the Issuer will deliver to the Trustee,
within 30 days after any Officer becomes aware of the occurrence of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect
thereto.

 The Issuer 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

 The Issuer and each of the Guarantors 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 Issuer and each of the Guarantors (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

or exchange; provided that any determination that the Fair Market Value of property received (other than of any asset with a public trading market) is in excess of $50.0 million shall be
made by an Independent Financial Advisor, which determination shall be evidenced by an opinion addressed to the Issuer and delivered to the Trustee; plus 
 (C) the amount by which Indebtedness or Disqualified Stock incurred or issued subsequent to the Issue Date is reduced on the Issuer’s consolidated balance sheet upon the conversion or exchange (other

 (D) to the extent not included in the calculation of the Consolidated Net Income referred to in (a), an amount
equal to, without duplication: 
 (i) 100% of the aggregate net proceeds (including the Fair Market Value of

 (ii) the net reduction in Investments (other than Permitted Investments) in any Person resulting from dividends, repayments
of loans or advances or other Transfers of assets subsequent to the Issue Date, in each case to the Issuer or any Restricted Subsidiary from such Person (including by way of such Person becoming a Restricted Subsidiary); plus 
 (iii) if the Basket was reduced as the result of the designation of a Restricted Subsidiary as an Unrestricted Subsidiary,
the portion (proportionate to the Issuer’s direct or indirect equity interest in such Subsidiary) of the Fair Market Value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted Subsidiary is redesignated, or liquidated
or merged into, a Restricted Subsidiary; 
 provided that the foregoing shall not exceed, in the aggregate, the amount of
all Investments which previously reduced the Basket.

 Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock. 
 (a) The Issuer will not, and will not permit any Restricted Subsidiary to, incur, directly or indirectly, any Indebtedness; provided
that the Issuer or any Restricted Subsidiary may incur Indebtedness if, immediately after giving effect to such incurrence, the Consolidated Coverage Ratio is at least 2.0 to 1.0 (determined on a pro forma basis, including a pro forma application of
the net proceeds therefrom, as if the additional Indebtedness had been incurred, and the application of the proceeds therefrom, had occurred at the beginning of the applicable four-quarter period), so long as the aggregate Indebtedness incurred
pursuant to this proviso by Restricted Subsidiaries that are not Subsidiary Guarantors does not exceed $50.0 million at any one time outstanding (this proviso, the “Coverage Ratio Exception”).

aggregate amount at any time outstanding pursuant to this clause (8) not to exceed $25.0 million; 
 (9) Indebtedness of any Foreign Subsidiary in an aggregate amount at any time outstanding pursuant to this clause (9) (after giving effect to the application of any net proceeds of such Indebtedness as of the date of the incurrence

 (11) customary indemnification, adjustment of purchase price or similar obligations, in each case, incurred in connection

 (12) obligations in respect of performance bonds and completion, guarantee, surety and similar

 (14) Indebtedness arising in connection
with endorsement of instruments for deposit in the ordinary course of business; 
 (15) Indebtedness consisting
of take-or-pay obligations contained in supply agreements relating to products, services or commodities of a type that the Issuer or any of its Subsidiaries uses or sells in the ordinary course of business; 
 (16) Acquired Indebtedness; provided that after giving effect to such acquisition or merger, either (i) the

prior to such acquisition or merger;

 56 








 (20) additional Indebtedness of the Issuer or any Restricted Subsidiary in
an aggregate principal amount not to exceed $75.0 million at any time outstanding pursuant to this clause (20). 
 (c) For
purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (20) of
Section 4.09(b) or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify such item of Indebtedness and may divide and classify such Indebtedness in more than one of the types of
Indebtedness described and may later reclassify such item into any one or more of the categories of Indebtedness described above (provided that at the time of reclassification it meets the criteria in such category or categories); provided,
however, that Indebtedness outstanding under the Credit Agreement on the Issue Date shall be deemed to have been incurred under clause (3) of Section 4.09(b). The maximum amount of Indebtedness that the Issuer or any Restricted
Subsidiary may incur pursuant to this Section 4.09 will not be deemed to be exceeded solely as the result of fluctuations in the exchange rates of currencies. In determining the amount of Indebtedness outstanding under one of the clauses above,
the outstanding principal amount of any particular Indebtedness of any Person shall be counted only once and any obligation of such Person or any other Person arising under any guarantee, Lien, letter of credit or similar instrument supporting such
Indebtedness shall be disregarded so long as it is permitted to be incurred by the Person or Persons incurring such obligation. 
 Accrual of interest or dividends, the accretion of accreted value, the accretion or amortization of original issue discount and the payment of interest or dividends in the form of additional Indebtedness, Disqualified Stock or Preferred
Stock, as the case may be, of the same class will not be deemed to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock; provided, in each such case, that the amount thereof is included in Consolidated Fixed Charges of the
Issuer as accrued. 
 For purposes of determining compliance with, and the outstanding principal amount of any particular
Indebtedness incurred pursuant to and in compliance with this Section 4.09, any other obligation of the obligor on such Indebtedness (or of any other Person who could have incurred such Indebtedness under this Section 4.09) arising under
any Guarantee, Lien or letter of credit, bankers’ acceptance or other similar instrument or obligation supporting such Indebtedness shall be disregarded to the extent that such Guarantee, Lien or letter of credit, bankers’ acceptance or
other similar instrument or obligation secures the principal amount of such Indebtedness. 
 (d) Notwithstanding any of the
foregoing to the contrary, the Issuer will not, and will not permit any Subsidiary Guarantor to, incur any Indebtedness that purports to be by its terms (or by the terms of any agreement or instrument governing such Indebtedness) subordinated in
right of payment to any other Indebtedness of the Issuer or of such other Subsidiary Guarantor, as the case may be, unless such Indebtedness is also by its terms made subordinated in right of payment to the Notes or the Guarantee of such Subsidiary
Guarantor, as applicable, to at least the same extent as such Indebtedness is subordinated in right of payment to such other Indebtedness of the Issuer or such Subsidiary Guarantor, as the case may be. 
 Section 4.10 Asset Sales. 
 (a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless: 
 (1) the Issuer or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets (the value of such consideration and the value of
such assets both measured as of the date of the definitive agreement with respect to such Asset Sale) included in such Asset Sale; and 
  

 57 








 (2) at least 75% of the total consideration received in such Asset Sale
consists of cash, Temporary Cash Investments or assets referred to in Section 4.10(c)(2), in each case, valued at the Fair Market Value thereof, or a combination of the foregoing. 
 For purposes of clause (2) of this Section 4.10(a), the following shall be deemed to be cash: 
 (A) the amount (without duplication) of any Indebtedness (other than Subordinated Obligations) of the Issuer or such Restricted Subsidiary that is expressly assumed by the Transferee in such Asset Sale
and with respect to which the Issuer or such Restricted Subsidiary, as the case may be, is unconditionally released by the holder of such Indebtedness; 
 (B) the amount of any obligations received from such Transferee that are within 180 days repaid, converted into or sold or otherwise disposed of for cash or Temporary Cash Investments (to the extent of
the cash or Temporary Cash Investments actually so received); and 
 (C) any Designated Noncash Consideration
received by the Issuer or any Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this clause since the Issue Date that is at the time
outstanding and held by the Issuer or any Restricted Subsidiary, not to exceed the greater of (x) $20.0 million or (y) 2.0% of Total Assets at the time of the receipt of such Designated Noncash Consideration, with the Fair Market Value of
each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value. 
 (b) If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary in connection with any Asset Sale is repaid, converted into or sold or otherwise disposed of for cash or
Temporary Cash Investments (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion, sale or other disposition shall be deemed to constitute the date of an Asset Sale hereunder and
the Net Available Proceeds thereof shall be applied in accordance with this Section 4.10. 
 (c) If the Issuer or any
Restricted Subsidiary engages in an Asset Sale, the Issuer or a Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply an amount equal to the Net Available Proceeds therefrom in any combination of one or more
of the following: 
 (1) to repay or otherwise retire Indebtedness (other than Subordinated Obligations) owing
under a Credit Facility that is secured by a Lien, which Lien is permitted by this Indenture, and if such Indebtedness that is repaid or otherwise retired is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

 (2) to make (i) an Investment in or expenditure for assets (including Capital Stock of any Person) that
replace the assets that were the subject of the Asset Sale (“Replacement Assets”), (ii) an Investment in or expenditure for assets (including Capital Stock of any Person) that will be used in the Permitted Business and
(iii) capital expenditures with respect to assets that will be used in the Permitted Business (assets described in clauses (ii) or (iii) of this Section 4.10(c) being referred to as “Useful Assets”);
provided, however, that if the assets that were the subject of

  

 58 








 
the Asset Sale were assets of the Issuer or any Subsidiary Guarantor, the Replacement Assets or Useful Assets, as the case may be, shall be assets of the Issuer or any Subsidiary Guarantor
immediately following the application of the Net Available Proceeds pursuant to this clause (2) (but may thereafter be transferred in accordance with this Indenture); and/or 
 (3) to enter into a binding commitment with respect to any Investment, expenditure for assets or capital expenditure pursuant
to clause (2) of this Section 4.10(c); provided that such binding commitment shall be treated as a permitted application of the Net Available Proceeds from the date of such commitment until and only until the earlier of (x) the
date on which such investment or expenditure is consummated and (y) the 180th day following the expiration of the aforementioned 365-day period, and if the Investment or expenditure contemplated by such binding commitment is not consummated on
or before the 180th day, such commitment shall be deemed not to have been a permitted application of Net Available Proceeds. 
 The amount of
Net Available Proceeds not applied or invested as provided in this Section 4.10(c) will constitute “Excess Proceeds.” 
 (d) When the aggregate amount of Excess Proceeds equals or exceeds $25.0 million, the Issuer will be required, within 5 days of any such occurrence, to make an offer to purchase from all Holders of Notes
an aggregate principal amount of Notes and, if the Issuer is required to do so under the terms of any other Indebtedness ranking pari passu with such Notes, such other Indebtedness on a pro rata basis with the Notes, equal to the amount of
such Excess Proceeds (a “Net Proceeds Offer”) in accordance with the procedures set forth in Section 3.09. 
 (e) The offer price for the Notes will be payable in cash and will be equal to 100% of the principal amount of the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest and Special Interest thereon, if any, to
the date such Net Proceeds Offer is consummated (the “Offered Price”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date. If the aggregate
Offered Price of Notes validly tendered and not withdrawn by Holders of Notes thereof exceeds the amount of Excess Proceeds, Notes to be purchased will be selected on a pro rata basis. Upon completion of such Net Proceeds Offer in accordance
with the foregoing provisions, the amount of Excess Proceeds shall be reduced to zero. 
 (f) To the extent that the aggregate
Offered Price of Notes tendered pursuant to a Net Proceeds Offer (and if applicable, the aggregate amount of pari passu Indebtedness being repaid, on a pro rata basis with the Notes) is less than the Excess Proceeds (such shortfall
constituting a “Net Proceeds Deficiency”), the Issuer may use the Net Proceeds Deficiency, or a portion thereof, for any purpose not prohibited by this Indenture. 
 (g) In the event of the Transfer of substantially all (but not all) of the assets of the Issuer and the Restricted Subsidiaries as an
entirety to a Person in a transaction covered by and effected in accordance with Section 5.01, the Transferee shall be deemed to have sold for cash at Fair Market Value the assets of the Issuer and the Restricted Subsidiaries not so Transferred
for purposes of this covenant, and shall comply with the provisions of this covenant with respect to such deemed sale as if it were an Asset Sale (with such Fair Market Value being deemed to be Net Available Proceeds for such purpose). 

(h) The Issuer shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other
securities laws or regulations in connection with any purchase of Notes pursuant to this Section 4.10. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this 4.10, the Issuer shall
comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of this compliance. 
  

 59 








 Section 4.11 Transactions with Affiliates. 
 (a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, in one transaction or series of related
transactions, Transfer any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any affiliate of the Issuer (an “Affiliate
Transaction”), unless the terms thereof are no less favorable to the Issuer or such Restricted Subsidiary than those that could be obtained at the time of such transaction in arm’s-length dealings with a Person that is not such an
affiliate. 
 (b) The Board of Directors must approve each Affiliate Transaction that involves aggregate payments or other
assets or services with a Fair Market Value in excess of $10.0 million. This approval must be evidenced by a board resolution that states that such board has determined that the transaction complies with the foregoing provisions. 
 (c) If the Issuer or any Restricted Subsidiary enters into an Affiliate Transaction that involves aggregate payments or other assets or
services with a Fair Market Value in excess of $25.0 million, then prior to the consummation of that Affiliate Transaction, the Issuer must obtain a favorable opinion from an Independent Financial Advisor that it has determined such Affiliate
Transaction to be fair, from a financial point of view, to the Holders of Notes, and deliver that opinion to the Trustee. 
 (d)
The provisions of clauses (a)-(c) of this Section 4.11 will not prohibit the following: 
 (1)
transactions exclusively between or among (i) the Issuer and one or more Restricted Subsidiaries or (ii) Restricted Subsidiaries; provided, in each case, that no affiliate of the Issuer (other than another Restricted Subsidiary)
owns more than 10% of the Capital Stock in any such Restricted Subsidiary; 
 (2) customary director, officer and
employee compensation (including bonuses) and other benefits (including retirement, health, stock option and other benefit plans) and indemnification arrangements, and agreements to register securities of directors, officers, employees or other
affiliates, in each case approved by the Board of Directors; 
 (3) loans or advances to employees in the
ordinary course of business in accordance with past practices of the Issuer or its Restricted Subsidiaries, but in any event not to exceed $5.0 million in the aggregate outstanding at any one time; 
 (4) Restricted Payments which are made in accordance with Section 4.07 and Investments constituting Permitted
Investments; 
 (5) any issuance by the Issuer or any Restricted Subsidiary of Qualified Stock; 
 (6) transactions between the Issuer or any Subsidiary and any Securitization Entity in connection with a Qualified
Securitization Transaction, in each case provided that such transactions are not otherwise prohibited by this Indenture; 
 (7) transactions with a Person (other than an Unrestricted Subsidiary of the Issuer) that is an affiliate solely because the Issuer or any Restricted Subsidiary owns Capital Stock in, or controls, such
Person; 
  

 60 








 (8) the sale to an Affiliate of the Issuer of Indebtedness of the Issuer in
connection with an offering of such Indebtedness in a market transaction and on terms substantially identical to those of other purchasers in such market transaction; and 
 (9) any agreement as in effect as of the Issue Date, or any amendment thereto or renewal or replacement thereof (so long as
any such amendment, renewal, or replacement is not disadvantageous to the holders of the Notes when taken as a whole as compared to the applicable agreement as in effect on the Issue Date). 
 Section 4.12 Liens. 
 The
Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur any Lien of any kind securing Indebtedness on any asset of the Issuer or any Restricted Subsidiary (including Capital Stock of a Restricted Subsidiary),
whether owned at the Issue Date or thereafter acquired, or any income or profits therefrom or assign or convey any right to receive income therefrom, except Permitted Liens, unless the Notes and the Guarantees are secured on an equal and ratable
basis with the obligations so secured until such time as such obligations are no longer secured by such a Lien; provided that if the obligations so secured are subordinated in right of payment by their terms to the Notes or a Guarantee, the
Lien securing such obligations will, by its terms, be junior in priority to the Lien securing the Notes and the Guarantees. Any Lien created for the benefit of the holders of the Notes pursuant to the preceding sentence will be automatically and
unconditionally released and discharged upon the release and discharge of each Lien which gave or would give rise to the obligation to create such Lien for the benefit of the holders of the Notes. 
 Section 4.13 Business Activities. 
 The Issuer will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than the Permitted Business. 
 Section 4.14 Corporate Existence. 
 Subject to Article 5 hereof, the Issuer 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 Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuer or any such Restricted Subsidiary; and

 (2) the rights (charter and statutory), licenses and franchises of the Issuer and its Restricted Subsidiaries;
provided, however, that the Issuer shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that
the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 

Section 4.15 Offer to Repurchase Upon Change of Control. 
 (a) Upon the occurrence of a Change of Control, each Holder shall have the right to require the Issuer to purchase all or a portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of
such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus

  

 61 








 
accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on
or prior to the date fixed for redemption), in accordance with the terms contemplated in Sections 3.09 and 4.15(b) (a “Change of Control Offer”). 
 (b) Within 30 days following any Change of Control, the Issuer shall mail a notice to each Holder, with a copy to the Trustee, stating 
 (1) that a Change of Control has occurred and that such Holder has the right to require the Issuer to purchase such
Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive
interest on an interest payment date that is on or prior to the date fixed for purchase); 
 (2) the purchase
date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and 
 (3) the instructions as determined by the Issuer, consistent with this Section 4.15, that a Holder must follow in order to have its Notes purchased. 
 (c) On the purchase date, all Notes purchased by the Issuer under this Section 4.15 shall be delivered to the Trustee for cancellation, and the Issuer shall pay the purchase price plus accrued and
unpaid interest, if any, to the Holders entitled thereto. 
 The Paying Agent will promptly mail (but in any case not later than
five days after the purchase date) to each Holder of Notes properly tendered the purchase price, 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 Issuer will publicly announce the results of the Change of Control Offer by or on, or as soon as practicable after, the purchase date. 
 (d) The Issuer shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other
securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 4.15. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, the Issuer
shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under any covenant of this Indenture by virtue of such compliance. 
 (e) Notwithstanding anything to the contrary in this Section 4.15, the Issuer will not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and purchases all Notes validly tendered and not withdrawn
under the Change of Control Offer. 
 (f) Notwithstanding anything to the contrary contained herein, a Change of Control Offer
may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

 Section 4.16 Limitation on Sale and Leaseback Transactions. 
 The Issuer will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction; provided that
the Issuer or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if: 
 (1) the Issuer or
such Restricted Subsidiary could have 
 (a) incurred Indebtedness in an amount equal to the Attributable Debt
relating to such Sale and Leaseback Transaction pursuant to Section 4.09 and 
 (b) incurred a Lien to
secure such Indebtedness pursuant to Section 4.12; 
 (2) the gross cash proceeds of such Sale and Leaseback
Transaction are at least equal to the Fair Market Value of the asset that is the subject of such Sale and Leaseback Transaction; and 
 (3) the Transfer of the asset in such Sale and Leaseback Transaction is permitted by, and Issuer applies the proceeds of such transaction in compliance with, the covenant described under
Section 4.10. 
 Section 4.17 Additional Guarantees. 
 If at any time after the Issue Date: 
 (1) the Issuer or any
Restricted Subsidiary acquires or creates another Restricted Subsidiary that is a Domestic Subsidiary (other than an Immaterial Subsidiary); 
 (2) any Immaterial Subsidiary that is both a Restricted Subsidiary and a Domestic Subsidiary ceases to meet the definition of Immaterial Subsidiary; or 
 (3) any Captive Insurance Company ceases to meet the definition thereof and is not designated as an Unrestricted Subsidiary
in accordance with this Indenture, 
 then, in each case, that newly acquired or created Restricted Subsidiary, former Immaterial Subsidiary or
former Captive Insurance Company shall, within 10 Business Days of the date on which it was acquired or created or ceases to meet the applicable definition, as the case may be, execute and deliver to the Trustee a supplemental indenture in form
reasonably satisfactory to the Trustee (it being agreed that the form of supplemental indenture attached as Exhibit E hereto is in form reasonably satisfactory to the Trustee) pursuant to which such Person shall fully and unconditionally guarantee
all of Issuer’s obligations under the Notes and this Indenture on the terms set forth in Section 10.01. Thereafter, such Person shall be a Subsidiary Guarantor for all purposes of this Indenture until released in accordance with the terms
of Section 10.04. 
 Section 4.18 Designation of Restricted and Unrestricted Subsidiaries. 
 (a) After the Issue Date, the Issuer may designate any Subsidiary of the Issuer (including any acquired or newly formed Subsidiary) to be an
Unrestricted Subsidiary unless such Subsidiary or any of its Subsidiaries owns any Capital Stock or Indebtedness of, or holds any Lien on any assets of, the Issuer or any other Subsidiary of the Issuer that is not a Subsidiary of the Subsidiary to
be so designated; provided that: 
 (1) no Default has occurred and is continuing or would occur as a
consequence thereof; 
  

 63 








 (2) (x) the Issuer could incur at least $1.00 of additional Indebtedness
pursuant to the Coverage Ratio Exception or (y) the Consolidated Coverage Ratio of the Issuer and the Restricted Subsidiaries is equal to or greater than immediately prior to such designation; and 
 (3) either (x) the Subsidiary to be so designated has total assets of $1,000 or less or (y) if such Subsidiary has
assets greater than $1,000, such designation would be permitted under Section 4.07 (treating the Fair Market Value of the Issuer’s proportionate interest in the net worth of such Subsidiary on such date calculated in accordance with GAAP
as the amount of the Investment). 
 Any designation of a Subsidiary of the Issuer 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. 
 (b) The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted
Subsidiary; provided that: 
 (1) no Default has occurred and is continuing; and 
 (2) Indebtedness of such Unrestricted Subsidiary and all Liens on any asset of such Unrestricted Subsidiary outstanding
immediately following such redesignation would, if incurred at such time, be permitted to be incurred under this Indenture. 
 Section 4.19
Special Interest Notice. 
 In the event that the Issuer is required to pay Special Interest to holders of Notes pursuant
to the Registration Rights Agreement, the Issuer will provide written notice (“Special Interest Notice”) to the Trustee of its obligation to pay Special Interest no later than fifteen days prior to the proposed payment date for the
Special Interest, and the Special Interest Notice shall set forth the amount of Special Interest to be paid by the Issuer on such payment date. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine
the Special Interest, or with respect to the nature, extent, or calculation of the amount of Special Interest owed, or with respect to the method employed in such calculation of the Special Interest. 
 ARTICLE 5 
 SUCCESSORS 
 Section 5.01 Merger, Consolidation or Sale of Assets. 
 (a) The Issuer will not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or Transfer

transaction have been satisfied and that supplemental indenture is enforceable. 
 Section 5.02 Successor Corporation Substituted.

 The Indenture provides that upon any consolidation or merger in which the Issuer is not the continuing Person,
or any Transfer of all or substantially all of the assets of the Issuer in accordance with Section 5.01, the Issuer Surviving Entity shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under this
Indenture and the Registration Rights Agreement with the same effect as if such the Issuer Surviving Entity had been named as such; provided, however, that the predecessor Issuer shall not be relieved from the
obligation to pay the principal of, premium on, if any, and interest and Special Interest, if any, on, the Notes except in the case of a sale of all or substantially all of the Issuer’s assets in a transaction that is subject to, and that

 ARTICLE 6 
 DEFAULTS AND REMEDIES 
 Section 6.01
Events of Default. 
 Any of the following shall constitute an “Event of Default”: 
 (1) default for 30 days in the payment when due of interest and Special Interest, if any, on, the Notes; 
 (2) default in the payment when due of principal on any Note, whether upon maturity, acceleration, optional redemption,
required repurchase or otherwise; 
  

 66 








 (3) failure by the Issuer to comply with the provisions of Sections 4.15;

 (4) failure by the Issuer or any of its Restricted Subsidiaries to perform or comply with any covenant,
agreement or warranty in this Indenture (other than any specified in clauses (1), (2) or (3) of this Section 6.01) which failure continues for 60 days after written notice thereof has been given to the Issuer by the Trustee or to the
Issuer and the Trustee by the holders of at least 25% in aggregate principal amount of the Notes then outstanding; 
 (5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Issuer or any Restricted Subsidiary, whether such Indebtedness
now exists or is created after the Issue Date, which 
 (A) is caused by a failure to pay such Indebtedness at
Stated Maturity (after giving effect to any grace period related thereto) (a “Payment Default”); or 
 (B) results in the acceleration of such Indebtedness prior to its Stated Maturity; 
 and in each case, the principal
amount of any such Indebtedness as to which a Payment Default or acceleration shall have occurred, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $20.0 million or more; 
 (6) one or more final and non-appealable judgments, orders or
decrees for the payment of money of $20.0 million or more, individually or in the aggregate, shall be entered against the Issuer or any Restricted Subsidiary or any of their respective properties and which final and non-appealable judgments, orders
or decrees are not covered by third party indemnities or insurance as to which coverage has not been disclaimed and are not paid, discharged, bonded or stayed within 60 days after their entry; 
 (7) a court having jurisdiction in the premises enters (x) a decree or order for relief in respect of Parent, the Issuer
or any of its Significant Subsidiaries in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or (y) a decree or order adjudging Parent, the Issuer or any of its
Significant Subsidiaries a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of Parent, the Issuer or any of its Significant Subsidiaries under any
applicable federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of Parent, the Issuer or any of its Significant Subsidiaries or of any substantial part of its property, or
ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; 
 (8) Parent, the Issuer or any of its Significant Subsidiaries: 
 (A) commences a voluntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or
other similar law or any other case or proceeding to be adjudicated a bankrupt or insolvent; or 
  

 67 








 (B) consents to the entry of a decree or order for relief in respect of the
Issuer or any of its Significant Subsidiaries in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or
proceeding against the Issuer or any of its Significant Subsidiaries; or

 (F) admits in writing its inability to pay its debts generally as they become due; or 
 (G) takes corporate action in furtherance of any such action; or 
 (9) the Guarantee of Parent or any Subsidiary Guarantor that is a Significant Subsidiary ceases to be in full force and
effect (other than in accordance with the terms of such Guarantee and this Indenture) or is declared null and void and unenforceable or is found invalid or any Guarantor denies its liability under its Guarantee (other than by reason of release of a
Guarantor from its Guarantee in accordance with the terms of this Indenture and the Guarantee). 
 Section 6.02 Acceleration. 

If an Event of Default occurs and is continuing (other than an Event of Default described in clause (7) or (8) of
Section 6.01 with respect to Parent, Issuer or any Guarantor that is a Significant Subsidiary), the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes may declare the principal of and accrued but unpaid interest
and Special Interest, if any, on all the Notes to be due and payable. Upon such a declaration, such principal and interest and Special Interest, if any, shall be due and payable immediately. If an Event of Default described in clause (7) or
(8) of Section 6.01 occurs with respect to Parent, Issuer or any Guarantor that is a Significant Subsidiary, the principal of and interest on all the Notes will ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders of the Notes. The Holders of a majority in aggregate principal amount of the outstanding Notes by notice to the Trustee may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect
any subsequent Default or impair any right consequent thereto. 
 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 of or
interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  

 68 








 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does
not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. No remedy is exclusive of any other remedy. All available remedies are, to the extent permitted by law, cumulative. 
 Section
6.04 Waiver of Past Defaults. 
 The Holders of a majority in aggregate principal amount of the Notes then outstanding by
notice to the Trustee may waive any past or existing Default and its consequences except (i) a Default in the payment of the principal of or interest on a Note or (ii) a Default in respect of a provision that under Section 9.2 cannot
be amended without the consent of each Holder affected. When a Default is waived, it is deemed cured, and any Event of Default arising therefrom shall be deemed to have been cured, but no such waiver shall extend to any subsequent or other Default
or impair any consequent right. 
 Section 6.05 Control by Majority. 
 The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee
determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee shall have no duty to make such determination) or that would involve the Trustee in personal liability; provided, however, that the Trustee may
take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to reasonable indemnification from the Holders satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such action. 
 Section 6.06 Limitation on Suits. 

Except to enforce the right to receive payment of principal or interest when due, a Holder may not pursue any remedy with respect to this
Indenture or the Notes unless: 
 (1) such Holder has previously given the Trustee written notice that an Event
of Default is continuing; 
 (2) Holders of at least 25% in principal amount of the outstanding Notes have
requested in writing that the Trustee pursue the remedy; 
 (3) such Holders have offered the Trustee security or
indemnity satisfactory to it against any loss, liability or expense; 
 (4) the Trustee has not complied with
such request within 60 days after the receipt thereof and the offer of security or indemnity; and 
 (5) the
Holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period. 
 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative
duty to ascertain whether or not such actions or forbearances are unduly prejudicial to any Holder). 
  

 69 








 Section 6.07 Rights of Holders To Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium (if any) or interest
on the Notes held by such Holder, on or after the respective due dates therefor, or to bring suit for the enforcement of any such payment on or after such respective dates, 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 6.01(2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer for the
whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07. 
 Section 6.09 Trustee May File Proofs of Claim. 
 The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to Issuer, its creditors or its property and, unless prohibited by
law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make
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 it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. 
 Section 6.10 Priorities.

 If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the
following order, subject to applicable law: 
 FIRST: to the Trustee for amounts due under Section 7.07; 
 SECOND: to Holders for amounts due and unpaid on the Notes for principal and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Notes for principal and interest, respectively; and 
 THIRD: to the Issuer.

 The Trustee may, upon prior written notice to the Issuer, fix a record date and payment date for any payment to Holders
pursuant to this Section 6.10. At least 15 days before such record date, the Issuer shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid. 
 Section 6.11 Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing

  

 70 








 
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 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Notes.

 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 prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
 (b) Except during the continuance of an Event of Default: 
 (1) the duties of the Trustee will be determined solely by the express provisions of 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 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are
specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture, but need not confirm or investigate the accuracy of
mathematical calculations or other facts stated therein. 
 (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this
paragraph does not limit the effect of paragraph (b) of this Section 7.01; 
 (2) the Trustee will not
be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 6.05 hereof. 
 (d) Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section 7.01. 
 (e) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights and powers under
this Indenture at the request of any Holders, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. 
  

 71 








 (f) The Trustee will not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
 Section 7.02 Rights of Trustee. 
 (a) The Trustee may conclusively rely and
shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.
However, the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine
the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 
 (b) Before the Trustee acts or refrains from acting, it may 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 consult with counsel and the opinion or written advice of such counsel or any
Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed
with due care.

 (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, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 (h) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received
by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. 
 (i) The
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent,
custodian and other Person employed to act hereunder, 
  

 72 








 (j) The Trustee shall not be required to give any bond or surety in respect of the
performance of its powers and duties hereunder.

 Section 7.03 Individual Rights of Trustee. 
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer 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. 
 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 Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’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 occurs and is continuing and is known to the Trustee, the Trustee shall mail to each Holder of Notes notice of
the Default within 90 days after it occurs. Notwithstanding the foregoing, except in the case of a Default in the payment of principal of or interest on any Note, the Trustee may withhold notice if and so long as a committee of its trust officers
determines that withholding notice is in the interest 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 Issuer 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 Issuer will promptly notify the Trustee in writing when the Notes are listed on any stock exchange and of any delisting thereof.

  

 73 








 Section 7.07 Compensation and Indemnity. 
 (a) The Issuer will pay to the Trustee from time to time such compensation as shall be agreed in writing between the Issuer and the Trustee
for its acceptance of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuer 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 Issuer and the Guarantors will jointly and severally indemnify the Trustee and any predecessor Trustee against any
and all losses, liabilities, damages, claims or expenses (including taxes, other than taxes based on the income of the Trustee) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture,
including the costs and expenses of enforcing this Indenture against the Issuer and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other
Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct. The Trustee will
notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer will not relieve the Issuer or any of the Guarantors of their obligations hereunder. The Issuer or such Guarantor will defend the
claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuer will pay the reasonable fees and expenses of such counsel. Neither the Issuer nor any Guarantor need pay for any settlement made without its
consent, which consent will not be unreasonably withheld. 
 (c) The obligations of the Issuer and the Guarantors under this
Section 7.07 will survive the satisfaction and discharge of this Indenture. 
 (d) To secure the Issuer’s and the
Guarantors’ 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 of, premium on, if any, or interest
or Special Interest, if any, 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(7) or (8) 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 Issuer. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The
Issuer may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 hereof; 

 

 74 








 (2) the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law; 
 (3) a custodian or public officer
takes charge of the Trustee or its property; or 
 (4) the Trustee becomes incapable of acting. 
 (c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer will promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the
Issuer. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the
retiring Trustee, the Issuer, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Trustee.

 (e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with
Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee will become effective,
and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as
Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08,
the Issuer’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee. 
 Section 7.09 Successor
Trustee by Merger, etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its
corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee. 
 Section
7.10 Eligibility; Disqualification. 
 There will at all times be a Trustee hereunder that is a corporation organized and
doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has
a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who satisfies the requirements of TIA §310(a)(1), (2) and (5). The Trustee is subject to TIA §310(b).

 ARTICLE 8 
 DISCHARGE OF INDENTURE AND DEFEASANCE 
 Section 8.01 Discharge of Liability on Notes; Defeasance. 
 (a) This Indenture will be discharged and will cease
to be of further effect as to all Notes issued hereunder, when: 
 (1) either: 
 (a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes
for whose payment money has been deposited in trust and thereafter repaid to the Issuer, have been delivered to the Trustee for cancellation; or 
 (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within
one year and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination
thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and
interest and Special Interest, if any, to the date of maturity or redemption; 
 (2) in respect of subclause
(b) of clause (1) of this Section 8.01(a), no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such
deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to
which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and
any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings); 
 (3) the Issuer or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and 
 (4) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case
may be. 
 In addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all
conditions precedent to satisfaction and discharge have been satisfied. 
  

 76 








 Notwithstanding the satisfaction and discharge of this Indenture, if money has been
deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 8.01(a), the provisions of Sections 8.03 and 8.04 hereof will survive. In addition, nothing in this Section 8.01(a) will be deemed to discharge
those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 
 (b) Subject to Sections 8.02 and 8.03, the Issuer at any time may terminate (i) all its obligations under the Notes and this Indenture (“legal defeasance option”) or (ii) its obligations under Sections 3.09, 4.03,
4.05, 4.07 through 4.13, inclusive, 4.15 through 4.18, inclusive, and the operation of Sections 6.01(4), 6.01(5), 6.01(6), 6.01(7) (but only with respect to Significant Subsidiaries), 6.01(8) (but only with respect to Significant Subsidiaries),
6.01(9), 5.01(c)(1) and 5.01(c)(2) (“covenant defeasance option”). The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. 
 If the Issuer exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default. If the
Issuer exercises its covenant defeasance option, payment of the Notes may not be accelerated due to a failure to comply with any of Sections 3.09, 4.03, 4.05, 4.07 through 4.13, inclusive, 4.15 through 4.18, inclusive, and the operation of
Section 6.01(4), 6.01(5), 6.01(6), 6.01(7) (but only with respect to Significant Subsidiaries), 6.01(8) (but only with respect to Significant Subsidiaries) or 6.01(9), 5.01(c)(1) and 5.01(c)(2). If the Issuer exercises its legal defeasance
option or its covenant defeasance option, each Guarantor will be released from all of its obligations under Article 10. 
 Upon
satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuer terminates. 
 (c) Notwithstanding clauses (a) and (b)(i) above, the Issuer’s obligations in Article II, 7.07, 7.08, 8.03, 8.04, 8.05 and 8.06
shall survive until the Notes have been paid in full. Thereafter, the Issuer’s obligations in Sections 7.07, 8.04 and 8.05 shall survive. 
 Section 8.02 Conditions to Defeasance. the Issuer may exercise its legal defeasance option or its covenant defeasance option only if: 
 (a) the Issuer irrevocably deposits in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations which through the scheduled payment of principal and interest
in respect thereof in accordance with their terms will provide cash (without reinvestment) at such times and in such amounts as will be sufficient to pay principal and interest on the Notes (except Notes replaced pursuant to Section 2.07) to
redemption or maturity, as the case may be; 
 (b) the Issuer delivers to the Trustee a certificate from a nationally recognized
firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such
times and in such amounts as will be sufficient to pay principal and interest when due on all outstanding Notes (except Notes replaced pursuant to Section 2.07) to maturity or redemption, as the case may be; 
 (c) 91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.01(7) or (8) with
respect to the Issuer occurs which is continuing at the end of the period; 
 (d) no default exists under any Indebtedness of
Parent or any Restricted Subsidiary; 
  

 77 








 (e) the Issuer delivers to the Trustee an Opinion of Counsel to the effect that the trust
resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; 
 (f) the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and
defeasance and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such
Opinion of Counsel must be based on a ruling of the Internal Revenue Service or change in applicable Federal income tax law); 
 (g) the Issuer delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes as contemplated by this Article 8 have been complied
with; and 
 (h) the Issuer shall have paid or duly provided for payment under terms mutually satisfactory to the Issuer and the
Trustee all amounts then due to the Trustee pursuant to Section 7.07. 
 Opinions of Counsel required to be delivered under
this Section may have qualifications customary for opinions of the type required and counsel delivering such Opinions of Counsel may rely on certificates of the Issuer or government or other officials customary for opinions of the type required,
including certificates certifying as to matters of fact. 
 Before or after a deposit, the Issuer may make arrangements
satisfactory to the Trustee for the redemption of Notes at a future date in accordance with Article 3. 
 Section 8.03 Application of Trust
Money. 
 The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8.
It shall apply the deposited money and the money from U.S. Government Obligations either directly or through the Paying Agent (including the Issuer acting as its own Paying Agent as the Trustee may determine) and in accordance with this Indenture to
the payment of principal of and interest on the Notes. 
 Subject to the provisions of Section 8.05 hereof, all money or
U.S. Government Obligations deposited with the Trustee pursuant to this Article 8 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 Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, and interest and Special Interest, if any, for whose payment such money has been deposited
with the Trustee; but such money need not be segregated from other funds except to the extent required by law. 
 If the Trustee
or Paying Agent is unable to apply any money or Government Securities in accordance with this Article 8 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Issuer’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8; provided that if
the Issuer has made any payment of principal of, premium on, if any, or interest or Special Interest, if any, on, any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money or Government Securities held by the Trustee or Paying Agent. 
  

 78 








 Section 8.04 Repayment to the Issuer. 
 The Trustee and the Paying Agent shall notify the Issuer of any excess money or securities held by them at any time and shall promptly turn

 Subject to any applicable abandoned
property law, the Trustee and the Paying Agent shall pay to the Issuer upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must
look to the Issuer for payment as general creditors. 
 Section 8.05 Indemnity for Government Obligations. 
 The Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S.
Government Obligations or the principal and interest received on such U.S. Government Obligations other than any such tax, fee or other charge which by law is for the account of the Holders of the defeased Notes; provided that the Trustee shall be
entitled to charge any such tax, fee or other charge to such Holders’ account. 
 Section 8.06 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any
legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under this Indenture and the Notes and the Guarantors’
obligations under this Indenture and the Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8; provided, however, that (a) if the Issuer has made any payment of interest on or principal of any Notes following the reinstatement of its obligations, the Issuer shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent and (b) unless otherwise required by any legal proceeding or any order or judgment of any court or
governmental authority, the Trustee or Paying Agent shall return all such money and U.S. Government Obligations to the Issuer promptly after receiving a written request therefor at any time, if such reinstatement of the Issuer’s obligations has
occurred and continues to be in effect. 
 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER

 The Issuer and the Trustee may amend this Indenture or the Notes without notice to or consent of any Holder: 
 (a) to cure any ambiguity, defect or inconsistency; 
 (b) to provide for the assumption by a successor Person of the obligations of the Issuer or any Guarantor under this Indenture in accordance with Article 5; 
 (c) to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued
in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code); 
  

 79 








 (d) to add a Guarantor; 
 (e) to release any Guarantor from its Guarantee when permitted by this Indenture;

power herein conferred upon the Issuer or any of its Subsidiaries; 
 (g) to comply with any requirement of the SEC in
connection with the qualification of this Indenture under the TIA; 
 (h) to make any other change that does not materially
adversely affect the rights of any Holder; or 
 (i) to conform the text of this Indenture, the Guarantees or the Notes to any
provision of the “Description of Notes” section of the Offering Circular, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Guarantees
or the Notes, which intent may be evidenced by an Officers’ Certificate to that effect. 
 The consent of the Holders is
not necessary under this Indenture to approve the particular form of any proposed amendment or waiver. It is sufficient if such consent approves the substance of the proposed amendment or waiver. 
 After an amendment or waiver under this Section becomes effective, the Issuer is required to mail to Holders a notice briefly describing
such amendment or waiver. However, the failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of the amendment or waiver under this Section. 
 Section 9.02 With Consent of Holders. 
 The Issuer and the Trustee may amend this Indenture, the Notes and the Guarantees with the consent of the Holders of a majority of the aggregate principal amount of the Notes then outstanding (including
consents obtained in connection with a tender offer or exchange for the Notes) and any past default or compliance with any provision may also be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding.
However, without the consent of each Holder of an outstanding Note affected thereby, no amendment or waiver may: 
 (a) reduce
the principal of or change the fixed maturity of any Note; 
 (b) alter the provisions with respect to the redemption or
purchase provisions of any Note or this Indenture in a manner adverse to the Holders of the Notes (other than the provisions of this Indenture relating to any offer to purchase required under Section 4.15); 
 (c) waive a redemption or purchase payment due with respect to any Note; 
 (d) reduce the rate of or change the time for payment of interest on any Note; 
 (e) waive a Default in the payment of principal or interest on the Notes (except that Holders of at least a majority in aggregate principal
amount of the then outstanding Notes may (x) rescind an acceleration of the Notes that resulted from a non-payment default and (y) waive the payment default that resulted from such acceleration); 
  

 80 








 (f) make the principal of or interest on any Note payable in money other than United States
Dollars; 
 (g) 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 on the Notes; 
 (h) make the Notes or any Guarantee
subordinated by their or its terms in right of payment to any other Indebtedness; 
 (i) release Parent or any Guarantor that is
a Significant Subsidiary from its Guarantee except in compliance with this Indenture; or 
 (j) make any change in the amendment
and waiver provisions of this Indenture. 
 It shall not be necessary for the consent of the Holders under this Section to
approve the particular form of any proposed amendment or waiver. It is sufficient if such consent approves the substance of the proposed amendment or waiver. 
 After an amendment or waiver under this Section becomes effective, the Issuer shall mail to Holders a notice briefly describing such amendment or waiver. The failure to give such notice to all Holders, or
any defect therein, shall not impair or affect the validity of an amendment or waiver. 
 Section 9.03 Compliance with Trust Indenture
Act. 
 Every amendment to this Indenture or the Notes shall comply with the TIA as then in effect. 
 Section 9.04 Revocation and Effect of Consents and Waivers. 
 A consent to an amendment or a waiver by a Holder of a Note shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting
Holder’s Note, even if notation of the consent or waiver is not made on the Note. An amendment or waiver becomes effective once the requisite number of consents are received by the Issuer or the Trustee. After an amendment or waiver becomes
effective, it shall bind every Holder. 
 The Issuer may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph,
those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 
 Section 9.05 Notation on or Exchange of Notes. 
 If an amendment changes the terms of a Note, the Trustee may
require the Holder of the Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder. 
  

 81 








 Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the
Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment. 
 Section 9.06 Trustee To Sign Amendments. 
 The Trustee shall sign any amendment authorized pursuant to this Article 9 (other than Section 9.01(4)) if the amendment does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and shall receive, and (subject to Section 7.01) shall be fully protected in
conclusively relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment complies with the provisions of this Article 9. 
 ARTICLE 10 
 NOTE GUARANTEES 
 Section 10.01 Guarantee. 
 (a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: 
 (1) the principal of, premium on, if any, and interest and Special Interest, if any, on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise,
and interest on the overdue principal of, premium on, if any, and interest and Special Interest, if any, on, the Notes, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in
full or performed, all in accordance with the terms hereof and thereof; and 
 (2) in case of any extension of
time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or
otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the
Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenant that this Guarantee will not be discharged except by complete performance of the
obligations contained in the Notes and this Indenture. 
  

 82 








 (c) If any Holder or the Trustee is required by any court or otherwise to return to the
Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by either to the Trustee or such Holder, this Guarantee, to the extent theretofore
discharged, will be reinstated in full force and effect. 
 (d) Each Guarantor agrees that it will not be entitled to any right
of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and
the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith
become due and payable by the Guarantors for the purpose of this Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under
the Guarantee. 
 Section 10.02 Limitation on Guarantor Liability. 
 Each Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the
Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of such Subsidiary Guarantor will be limited to the maximum amount that will,
after giving effect to such maximum amount and all other contingent and fixed liabilities of such Subsidiary Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or
payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under this Article 10, result in the obligations of such Subsidiary Guarantor under its Guarantee not constituting a
fraudulent transfer or conveyance. 
 Section 10.03 Execution and Delivery of Guarantee. 
 The execution on behalf of each Guarantor of this Indenture or a supplement thereto by one of its Officers shall be sufficient to evidence
its Guarantee as set forth in Section 10.01 hereof. 
 If an Officer whose signature is on this Indenture no longer holds
that office at the time the Trustee authenticates the Note, the Guarantee will be valid nevertheless. 
 The delivery of any
Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors. 
 In the event that, after the date of this Indenture, any Person is required by Section 4.17 to Guarantee the Notes, the Issuer will cause each such Person to comply with the provisions of
Section 4.17 and this Article 10, to the extent applicable. 
 Section 10.04 Releases. 
 (a) The Guarantee of a Subsidiary Guarantor will be automatically and unconditionally released and discharged upon any of the following:

 (1) the consummation of any sale or other disposition of all or substantially all of the assets of that
Subsidiary Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary of the Issuer, if the sale or other disposition does not
violate Section 4.10; 
  

 83 








 (2) the consummation of any sale or other disposition of Capital Stock of
that Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary of the Issuer, if the sale or other disposition does not violate Section 4.10 and the Subsidiary
Guarantor ceases to be a Restricted Subsidiary of the Issuer as a result of the sale or other disposition; 
 (3)
the designation of any Restricted Subsidiary that is a Subsidiary Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture; or 
 (4) the legal defeasance, covenant defeasance or satisfaction and discharge of this Indenture pursuant to Article 9,

 provided, in each such case, that the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel,
each stating that all conditions precedent provided for in this Indenture relating to such transactions have been complied with and that such release is authorized and permitted under this Indenture. 
 (b) The Guarantee of Parent will be automatically and unconditionally released and discharged only upon the legal defeasance, covenant
defeasance or satisfaction and discharge of this Indenture pursuant to Article 9; provided, in each such case, that the Issuer has delivered to the Trustee an Officers’ Certificate and an opinion of counsel, each stating that all
conditions precedent provided for in this Indenture relating to such transactions have been complied with and that such release is authorized and permitted under this Indenture. 
 (c) Any Guarantor not released from its obligations under its Guarantee as provided in this Section 10.04 will remain liable for the
full amount of principal of, premium on, if any, and interest and Special Interest, if any, on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

 7.875% Senior Notes due 2019 
 [Insert the Global Note Legend, if applicable pursuant to the
provisions of the Indenture] 
 [Insert the Private Placement Legend, if applicable pursuant to the provisions of the Indenture] 

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise
indicated. 
 (1) INTEREST. Koppers Inc., a Pennsylvania corporation (the
“Issuer”), promises to pay or cause to be paid interest on the principal amount of this Note at 7.875% per annum from
                     until maturity and shall pay the Special Interest, if any, payable pursuant to the Registration Rights Agreement referred to
below. The Issuer will pay interest and Special Interest, if any, semi-annually in arrears on December 1 and June 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest
Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if this Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be
                    . The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal
at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Special
Interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2)
METHOD OF PAYMENT. The Issuer will pay interest on the Notes (except defaulted interest) and Special Interest, if any, to the Persons who are registered Holders of Notes at the close
of business on the November 15 or May 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture
with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest and Special Interest, if any, at the office or agency of the Paying Agent and Registrar within the City and State of New York, or, at the
option of the Issuer, payment of interest and Special Interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds
will be required with respect to principal of, premium on, if any, and interest and Special Interest, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying
Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 (3) PAYING AGENT AND REGISTRAR. Initially,
Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without prior notice to the Holders of the Notes. The Issuer or any of its
Subsidiaries may act as Paying Agent or Registrar. 
  

 A-2 








 (4) INDENTURE. The Issuer issued the
Notes under an Indenture dated as of December 1, 2009 (the “Indenture”) among the Issuer, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Issuer. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. 
 (5) OPTIONAL REDEMPTION. 
 (a) At any time on or prior to December 1, 2012 the Issuer may, at its option on any one or more occasions, redeem Notes
in an aggregate principal amount not to exceed 35% of the aggregate principal amount of Notes issued under this Indenture at a redemption price of 107.875% of the principal amount, plus accrued and unpaid interest to the redemption date, with the
Net Cash Proceeds of one or more Equity Offerings; provided that: 
 (i) at least 65% of the aggregate
principal amount of Notes issued under this Indenture remains outstanding immediately after the occurrence of such redemption (excluding Notes held by the Issuer and its Subsidiaries); and 
 (ii) the redemption occurs within 90 days of the date of the closing of such Equity Offering. 
 (b) At any time prior to December 1, 2014, the Issuer may redeem all or a part of the Notes, upon not less than 30 nor
more than 60 days’ prior notice mailed by first-class mail to the registered address of each holder of Notes or otherwise delivered in accordance with the procedures of DTC, at a redemption price equal to 100% of the principal amount of the
Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Special Interest, if any, to the date of redemption, subject to the rights of the holders of record on the relevant record date to receive interest due on the
relevant interest payment date. 
 (c) Except pursuant to the preceding paragraphs, the Notes will not be
redeemable at the Issuer’s option prior to December 1, 2014. 
 (d) The Notes will be redeemable at the
option of the Issuer, in whole or in part, at any time on or after December 1, 2014 at the redemption prices (expressed as a percentage of principal amount) set forth below, plus accrued and unpaid interest thereon, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve month period beginning on December 1 of the years indicated below:

  

				
	 Year
	  	Redemption

	 2016
	  	101.313	% 
	 2017 and thereafter
	  	100.000	% 

 Unless the Issuer 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. 
  

 A-3 








 (6) MANDATORY
REDEMPTION. The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 (7) REPURCHASE AT THE OPTION OF HOLDER. 
 (a) If there is a Change of Control, the Issuer will be required to make an offer (a “Change of Control
Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Special Interest, if any, thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. Within ten days following any
Change of Control, the Issuer will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 
 (b) If the Issuer or a Restricted Subsidiary of the Issuer consummates any Asset Sales, within five days of each date on
which the aggregate amount of Excess Proceeds exceeds $25.0 million, the Issuer will make a Net Proceeds 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 the Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets in accordance with the Indenture to purchase, prepay or redeem the maximum principal amount of Notes and such other pari
passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer
price in any Net Proceeds Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest and Special Interest, if any, to the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the

 W I T N E S S E T H

 WHEREAS, the Issuer has heretofore executed and delivered to the Trustee an indenture (the “Indenture”),
dated as of December 1, 2009 providing for the issuance of 7.875% Senior Notes due 2019 (the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all

 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby
acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.
