 ARTICLE 2 
 THE SECURITIES 
 Section 2.01 Form and Dating. 
 (a) General. The U.S. Notes, the Canadian Notes and the Units and
the related Trustee’s certificates of authentication for the Notes will be substantially in the form of Exhibit A1, A2 and A3 attached hereto, respectively. The Securities may have notations, legends or endorsements required by law, stock
exchange rule or usage; provided, that any such notations, legends or endorsements are in a form acceptable to the applicable Issuer. Each Note will be dated the date of its authentication. 
 The terms and provisions contained in the Securities will constitute, and are hereby expressly made, a part of this Indenture and the
Issuers, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Security conflicts with the express
provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. 
 (b) Global Notes. U.S.
Notes and Canadian Notes issued in global form (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto) will be substantially in the form of Exhibit A1 and A2 attached
hereto, respectively. U.S. Notes and Canadian Notes issued in definitive form (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto) will be substantially in
the form of Exhibit A1 and A2 attached hereto, respectively. Any Notes issued as Additional Securities following a Separation Event shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. Each Global Note will
represent such of the outstanding Notes as will be specified therein and each shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and the aggregate principal amount of outstanding Notes represented
thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes
represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 
  

 41 








 (c) Units. The Units shall be substantially in the form of Exhibit A3 attached
hereto. Each Unit shall be deemed dated the date of the issuance of the underlying Notes. Until the occurrence of a Separation Event, the Notes shall be issued as part of a Unit, each Unit consisting of $653.85 principal amount of U.S. Notes and
$346.15 principal amount of the Canadian Notes. The Notes of each Issuer may not be separately transferred unless a Separation Event has occurred. The Units shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess
thereof, and each Unit shall be comprised of Notes having aggregate minimum denominations allocated as follows: (i) U.S. Notes in minimum denominations of $1,307.70 and integral multiples of $653.85 in excess thereof and (ii) Canadian
Notes in minimum denominations of $692.30 and integral multiples of $346.15 in excess thereof. Upon the occurrence of an acceleration pursuant to Section 6.02 hereof, the first lien collateral agent under the Existing Intercreditor Agreement
shall deliver the Separation Event Offer Notices. Upon the occurrence of a Separation Event, the Issuers will mail a notice of such event to the Trustee and Holders and will take all actions necessary to permit the Notes to be traded separately.

 Section 2.02 Execution and Authentication. 
 At least one Officer of each Issuer must sign the Notes issued by such Issuer for such Issuer by manual or facsimile signature. 

If an Officer whose signature is on a Note no longer holds that office at the time the Note is authenticated, the Note will nevertheless
be valid. 
 No Note will be valid until authenticated by the manual signature of authorized signatory of the Trustee. The
signature will be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee
will, upon receipt of a written order of the Issuers signed by two Officers of each Issuer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this
Indenture, including any Notes issued as Additional Securities. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuers 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 Issuers 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 Issuers. 
 Section 2.03 Registrar and Paying Agent. 
 The Issuers will maintain an office or agency where Units or, if
a Separation Event has occurred, 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
shall keep a register (the “Register”) of the Units and Notes and of their transfer and exchange. The Issuers 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
Issuers may change any Paying Agent or Registrar without notice to any

  

 42 








 
Holder. The Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar
or Paying Agent, the Trustee shall act as such. The Issuers or any of their Subsidiaries may act as Paying Agent or Registrar. 
 The Issuers initially appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Securities. 
 The Issuers initially appoint the Trustee to act as the Registrar and Paying Agent in connection with the Securities, until such time as the Trustee has resigned or a successor has been appointed pursuant
to Section 7.07, and to act as Custodian with respect to the Global Securities. 
 Section 2.04 Paying Agent to
Hold Money in Trust. 
 On or prior to 10:00 a.m. New York City time on each due date of the principal and interest on any
Security, the Issuers shall deposit with the Paying Agent a sum sufficient to pay such principal and interest on any Security as it becomes due. The Issuers shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying
Agent shall 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, if any, on the Securities, and shall notify the Trustee of any default by the
Issuers 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 Issuers 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 an Issuer or a Subsidiary) shall have no further liability for the money. If an Issuer or a Subsidiary acts as Paying Agent, it shall 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 an Issuer, the Trustee shall serve as Paying Agent for the Securities. 
 Section 2.05 Holder Lists. 
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the
Issuers shall furnish to the Trustee or cause the Registrar to furnish to the Trustee, at least five (5) 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 Securities; provided that as long as the Trustee is the Registrar, no such list need be furnished. 
 Section 2.06 Transfer and Exchange. 
 (a) Transfer and Exchange of Global Securities. A Global Security 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 Securities shall be exchanged by the Issuers for Definitive Securities only
in the following limited circumstances: 
 (1) the Issuers deliver, or in the case of a Separation Event an
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 at a time when it is required to be so registered
in order to act as depository and, in each case, a successor Depositary is not appointed by the Issuers, or in the case of a Separation Event an Issuer, within 120 days after the date of such notice from the Depositary;

effect to the Trustee; or

Securities shall be issued in such names as the Depositary shall instruct the Trustee. Global Securities also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Security or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Security. A Global Security

interest. Beneficial interests in the Restricted Global Securities will be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global

hereof.

 (i) if the holder of such beneficial
interest in a Restricted Global Security proposes to exchange such beneficial interest for a beneficial interest in an Unrestricted Global Security, a certificate from such holder in the form of Exhibit C hereto, including the certifications in item

certifications in item (4) thereof; 
 and, in each such case set forth in this subparagraph (4), if the applicable Issuer

transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act. 
 If any such transfer is effected pursuant to subparagraph (4) above at a time when an Unrestricted Global Security has not yet been issued, the Issuers shall issue and, upon receipt of an
Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred

 51 








 
REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING.”

 (g)
Cancellation and/or Adjustment of Global Securities. At such time as all beneficial interests in a particular Global Security have been exchanged for Definitive Securities or a particular Global Security has been redeemed, repurchased or
canceled in whole and not in part, each such Global Security will be returned to or retained and canceled by the Trustee in accordance with Section 2.10 hereof. At any time prior to such cancellation, if any beneficial interest in a Global
Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Definitive Securities, the amount of Units or the principal amount of Notes represented by
such Global Security, as the case may be, will be reduced accordingly and an endorsement will be made on such Global Security 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 Security, such other Global Security will be increased accordingly and an endorsement will be made on
such Global Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. At any time prior to such cancellation, if any beneficial interest in a Definitive Security is exchanged for or transferred to a
Person who will take delivery thereof in the form of a beneficial interest in a Global Security, the amount of Units or the principal amount of Notes represented by such Global Security, as the case may be, will be increased accordingly and an
endorsement will be made on such Global Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (h) General Provisions Relating to Transfers and Exchanges. 
 (1) To permit registrations of transfers and exchanges, the Issuers 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 Security or to a Holder of a Definitive Security for any registration of transfer or exchange, but the Issuers 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, 3.07, 3.08, 4.10, 4.15, 4.20 and 9.04 hereof). 
 (3) All Global Securities and Definitive Securities issued upon any registration of transfer or exchange of Global Securities
or Definitive Securities will be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Securities or Definitive Securities surrendered upon such registration of transfer
or exchange. 
 (4) Neither the Registrar nor the Issuers will be required: 
 (A) to issue, to register the transfer of or to exchange any Securities during a period beginning at the opening of business
fifteen (15) days before the day of any selection of Securities for redemption under Section 3.03 hereof and ending at the close of business on the day of selection; 
  

 53 








 (B) to register the transfer of or to exchange any Security selected for
redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part; or 
 (C)
to register the transfer of or to exchange a Security between a record date and the next succeeding interest payment date. 
 (5) Prior to due presentment for the registration of a transfer of any Security, the Trustee, any Agent and the Issuers may deem and treat the Person in whose name any Security is registered as the
absolute owner of such Security for the purpose of receiving payment of principal of and (subject to the record date provisions of the Notes) interest on such Securities and for all other purposes, and none of the Trustee, any Agent or the Issuers
shall be affected by notice to the contrary. 
 (6) The Trustee will authenticate Global Notes and Definitive
Notes in accordance with the provisions of Section 2.02 hereof. 
 (7) 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. 
 Neither the Trustee nor the Registrar shall have any 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 Participants, members or beneficial owners in any Global Security) 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. 
 The Trustee shall retain copies of all letters, notices and other written
communications received pursuant to this Section 2.06 (including all Securities received for transfer pursuant to this Section 2.06). The Issuers shall have the right to require the Trustee to deliver to the Issuers, at their expense,
copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Trustee. 
 In connection with any transfer of any Security, the Trustee and the Issuers shall be entitled to receive, shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be
fully protected in relying upon the certificates, opinions and other information referred to herein (or in the forms provided herein, attached hereto or to the Security, or otherwise) received from any Holder and any transferee of any Security
regarding the validity, legality and due authorization of any such transfer, the eligibility of the transferee to receive such Security and any other facts and circumstances related to such transfer. 
 Section 2.07 Replacement Securities. 
 If any mutilated Securities are surrendered to the Trustee or the Issuers or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the applicable Issuer will
issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Security if the Holder satisfies any reasonable requirements of the Trustee and the Issuers. If required by the Trustee or the Issuers, an indemnity bond
must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from

  

 54 








 
any loss that any of them may suffer if a Security is replaced. The Issuers and the Trustee may charge the Holders for each of its expenses in replacing a Security. 
 In case any such mutilated, destroyed, lost, or stolen Security has become or is about to become due and payable, the applicable Issuer in
its sole discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under
this Section 2.07, the applicable Issuer may require the payment of a sum sufficient to cover any tax, assessment, fee or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses
of the Trustee) connected therewith. 
 Every new Security issued pursuant to this Section 2.07 in exchange for any
mutilated Security or in lieu of any destroyed, lost, or stolen Security will constitute an original additional contractual obligation of the applicable Issuer, whether or not the mutilated, destroyed, lost, or stolen Security shall be at any time
enforceable by anyone, and will be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
 The provisions of this Section 2.07 are exclusive and will preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost, or
stolen Securities. 
 Section 2.08 Outstanding Securities. 
 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 Security 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 Security does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Security; however, Securities held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of
Section 3.01(a) hereof. 
 If a Security is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding
unless the Trustee and the Issuers receive proof satisfactory to them that the replaced Security is held by a protected purchaser. A mutilated Security ceases to be outstanding upon surrender of such Security and replacement thereof pursuant to
Section 2.07. If the principal amount of any Security 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 an Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Securities payable on that date, then on and after that date such Securities will be deemed to be no longer outstanding and will cease to accrue interest. 
 Section 2.09 Treasury Securities. 
 In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Issuers or any Guarantor, or by any Person
directly or indirectly controlling or controlled by or under direct or indirect common control with an 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 Securities that the Trustee knows are so owned will be so disregarded. 
  

 55 








 Section 2.10 Temporary Securities. 
 Until certificates representing Securities are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication
Order, will authenticate temporary Notes. Temporary Securities will be substantially in the form of certificated Securities but may have variations that the Issuers consider appropriate for temporary Securities and as may be reasonably acceptable to
the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Securities will be entitled to all of the benefits of this Indenture. 
 Section 2.11 Cancellation. 
 The Issuers at any time may deliver
Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or cancellation. The Trustee shall dispose of all cancelled Securities in accordance with its customary procedures and shall deliver a certificate of disposition to the
applicable Issuer. Subject to Section 2.07, the Issuers may not issue new Securities to replace Securities that have been paid or that have been delivered to the Trustee for cancellation. 
 Section 2.12 Defaulted Interest. 
 If an Issuer defaults in a payment of interest on the Securities, 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 Issuers 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 Issuers 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 ten (10) days prior to the related
payment date for such defaulted interest. At least fifteen (15) days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) 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 Issuance of Additional Securities. 
 The Issuers shall be entitled, from time to time, subject
to its compliance with Section 4.09 and Section 4.12 hereof, without consent of the Holders, to issue Additional Securities under this Indenture with identical terms as the Notes other than with respect to (i) the date of issuance,
(ii) the issue price, (iii) the amount of interest payable on the first interest payment date, initial interest accrual date and initial interest payment date and (iv) any adjustments in order to conform to and ensure compliance with
the Securities Act (or other applicable securities laws). The Initial Notes and any Notes issued as Additional Securities shall be treated as a single class for all purposes under this Indenture. 
 With respect to any Additional Securities, the Issuers shall set forth in an Officers’ Certificate pursuant to a resolution of the
Board of Directors of each of the Issuers, copies of which shall be delivered to the Trustee, the following information: 
 (1) The number of Units to be issued as Additional Securities and the aggregate principal amount of Notes constituting Additional Securities to be authenticated and delivered pursuant to this Indenture;
and

under or with respect to the Notes, any Additional Amounts as a result of any change or amendment to the laws (or regulations promulgated thereunder) of Canada (or any subdivision thereof or by
any authority or agency therein or thereof having power to tax), or any change in or amendment to any official position or administration or assessing practices regarding the application or interpretation of such laws or regulations, which change or
amendment is announced or becomes effective on or after the original issue date of the Notes, the Notes held by such Holder will be subject to redemption, as Units, at the joint option of the Issuers, as a whole but not in part, at any time upon not
fewer than thirty (30) nor more than sixty (60) days’ notice at a redemption price equal to 100% of the principal amount of the Notes plus accrued interest to but excluding the redemption date. 
 (e) Mandatory Redemption. Except pursuant to this Section 3.01(e), the Issuers are not required to make mandatory redemption or
sinking fund payments with respect to the Notes. If the Second Lien Debt has not been repurchased, redeemed, defeased, refinanced or otherwise retired in accordance with the terms of this Indenture on or prior to January 21, 2013, then the
Issuers shall jointly issue an irrevocable notice of redemption on such date to jointly redeem all of the outstanding Notes as Units on February 19, 2013 at the applicable redemption price (expressed as percentages of principal amount) set
forth for such date, plus accrued and unpaid interest on the Notes redeemed, to the applicable date of redemption, under Section 3.01(c) hereof, subject to the rights of Holders of Notes on the relevant record date to receive interest on the
relevant interest payment date. Prior to giving the foregoing notice of redemption, the Issuers shall give the Trustee an Officers’ Certificate stating that all conditions precedent provided for herein to such redemption have been complied
with. 
 (f) Any redemption pursuant to this Section 3.01 shall include the U.S. Notes and the Canadian Notes on a pro
rata basis and be made pursuant to the provisions of Sections 3.02 through 3.07 hereof. 
 Section 3.02 Notices to
Trustee. 
 If the Issuers jointly elect to redeem Notes pursuant to Section 3.01 hereof, they shall notify the Trustee
in writing of the redemption date, the principal amount of Notes to be redeemed, the redemption price and the paragraph of the Notes pursuant to which the redemption will occur. The Issuers shall give such notice to the Trustee at least five
(5) days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to Section 3.01 hereof unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’
Certificate from the Issuers to the effect that such redemption will comply with the provisions herein. Such Officers’ Certificate shall also state that all conditions precedent, if any, provided for herein to such redemption have been complied
with. 
 Section 3.03 Selection of Notes to Be Redeemed or Purchased. 
 If less than all of the Notes are to be redeemed or repurchased in an offer to purchase at any time, the Trustee will select Notes for
redemption or purchase as Units on a pro rata basis (provided that, in the case of Notes issued in global form pursuant to Article 2 hereof, the Depositary may select interests in the Notes for redemption or purchase pursuant to its applicable
procedures) unless otherwise required by law or applicable stock exchange or depositary requirements. The Trustee shall make the selection from outstanding Notes not previously called for redemption or purchase. Prior to a Separation Event, Units
consisting of Notes having an aggregate principal amount in excess of $2,000 may be redeemed or purchased in part but only in whole multiples of $1,000, and after a Separation Event, U.S. Notes in denominations larger than $1,307.70 may be redeemed
or purchased in part but only in multiples of $653.85, and Canadian Notes in denominations larger than $692.30 may be redeemed or purchased in part but only in multiples of $346.15, except that if all of the Units or Notes of a Holder are to be
redeemed or purchased, the entire outstanding amount of Notes or Units held by such Holder shall be redeemed or

  

 58 








 
purchased. In connection with any pro rata selection of Notes for purchase or redemption, the Trustee may make such adjustments downward or upward (by not more than $1,000) so that Notes shall
only be redeemed or purchased in authorized denominations. 
 If any Unit or Note is to be redeemed or purchased in part only,
the notice relating to such Unit or Note shall state the portion of the principal amount thereof to be redeemed or purchased. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation of the original Note. Provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. The Trustee shall notify the Issuers promptly of the Notes
or portions of Notes to be redeemed or purchased. 
 Section 3.04 Notice of Redemption. 
 At least thirty (30) days but not more than sixty (60) days before a redemption date, the Issuers 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 sixty (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 Articles 8 or 11 hereof. 
 The notice will identify the Notes to be redeemed and shall state: 
 (1) the redemption date;

 (2) the redemption price (or if not then ascertainable, the manner of calculation thereof); 
 (3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after
the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 
 (4) the name and address of the Paying Agent; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
 (6) that, unless the Company defaults in making such redemption payment, interest on Notes 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; 
 (8) the CUSIP number, if any, printed on
the Notes being redeemed; and 
 (9) that no representation is made as to the correctness or accuracy of the
CUSIP numbers, if any, listed in such notice or printed on the Notes or the Units being redeemed. 
 At the Issuers’
request, the Trustee shall give the notice of redemption in the Issuers’ names and at their expense; provided, however, that such request by the Issuers to the Trustee is received by the Trustee at least five (5) Business Days prior
to the date the Trustee is requested to give notice to the

  

 59 








 
Holders whose Notes are to be redeemed. In such event, the Issuers shall provide the Trustee with the information required by this Section 3.04. 
 Section 3.05 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 3.04 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price stated in the
notice. A notice of redemption may not be conditional. Upon surrender to the Paying Agent, such Notes shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date. Such notice if mailed in the manner
herein provided shall be conclusively presumed to have been given, whether or not the Holder receives such notice. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

 Section 3.06 Deposit of Redemption or Purchase Price. 
 Prior to 10:00 a.m. (New York City time) on the redemption date or Purchase Date, the Issuers shall deposit with the Trustee or Paying Agent
(or, if the Issuers or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption or purchase price of and accrued interest (if any) on all Notes or portions thereof to be redeemed or purchased on
that date. The Trustee or the Paying Agent shall promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of and accrued
interest, if any, on all Notes to be redeemed or purchased. 
 If the Issuers comply 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 Issuers 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 3.07 Notes Redeemed or Purchased in Part. 
 Upon surrender of a
Note that is redeemed or purchased in part (with, if the Issuers or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuers and the Trustee duly executed by, the Holder thereof or his
attorney duly authorized in writing), the Issuers shall execute, and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered, except that if a Global Note is so surrendered, the Issuers shall execute, and the Trustee shall authenticate and deliver to
the Depository for such Global Note, without service charge, a new Global Note in denomination equal to and in exchange for the unredeemed portion of the principal of the Global Note so surrendered. 
 Section 3.08 Offer to Purchase by Application of Excess Proceeds. 
 In the event that, pursuant to Section 4.10 hereof, the Issuers are required to commence a joint offer to all Holders to purchase Notes
as Units (an “Asset Sale Offer”), they will follow the procedures specified below. 
  

 60 








 The Asset Sale Offer shall be made to all Holders and all holders of other Parity Lien Debt
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 Asset Sale Offer will remain open for a period of at least twenty (20) Business
Days following its commencement and not more than thirty (30) Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five (5) Business Days after the
termination of the Offer Period (the “Purchase Date”), the Issuers will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Parity Lien Debt (on a pro rata basis based on
the principal amount of Notes and such other Parity Lien Debt surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. 
 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, 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 Asset Sale Offer. 
 Upon the commencement of an Asset Sale Offer, the Issuers will send, by first class mail, a notice to the Trustee and each of the Holders,
with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

 (1) that the Asset Sale Offer is being made pursuant to this Section 3.08 and Section 4.10 hereof
and the length of time the Asset Sale Offer will remain open; 
 (2) the Offer Amount, the purchase price and the
Purchase Date; 
 (3) that any Note not tendered or accepted for payment will continue to accrue interest;

 (4) that, unless the Issuers default in making such payment, any Note accepted for payment pursuant to the
Asset Sale Offer will cease to accrue interest after the Purchase Date; 
 (5) that, prior to a Separation Event,
Holders electing to have a Note purchased pursuant to an Asset Sale 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 Asset Sale Offer will be required to surrender the Note,
with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer a beneficial interest in the Notes by book-entry transfer, to the Issuers, a depositary, if appointed by the Issuers, or a Paying
Agent at the address specified in the notice at least three (3) days before the Purchase Date; 
 (7) that
Holders will be entitled to withdraw their election if the Issuers, the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase , the serial number of such Note if held in definitive form, 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 Parity Lien Debt surrendered by holders thereof
exceeds the Offer Amount, the Company will select the Notes and other Parity

  

 61 








 
Lien Debt to be purchased on a pro rata basis based on the principal amount of Notes and such other Parity Lien Debt surrendered; 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
Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all
Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate of the applicable Issuer stating that such Notes or portions thereof were accepted for payment by the
Issuers in accordance with the terms of this Section 3.08. The Issuers, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five (5) Business 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 Issuers for purchase. Upon surrender of a Note that is purchased in part, the Issuers shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unpurchased portion of the
principal of the Note so surrendered, except that if a Global Note is so surrendered, the Issuers shall execute, and the Trustee shall authenticate and deliver to the Depository for such Global Note, without service charge, a new Global Note in
denomination equal to and in exchange for the unpurchased portion of the principal of the Global Note so surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers will publicly
announce the results of the Asset Sale Offer on the Purchase Date. 
 Other than as specifically provided in this
Section 3.08, any purchase pursuant to this Section 3.08 shall be made pursuant to the provisions of Sections 3.03, 3.06 and 3.07 hereof.

such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 
 The
Issuers 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 Issuers of their obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Issuers 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 Issuers 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 resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

restrictions existing under or by reason of: 
 (1) agreements governing Existing Indebtedness as in effect on
the date of this Indenture and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements,
refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of this Indenture (as determined in
good faith by the Company);

Stock of Persons acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Persons, or the properties or assets of any Persons, other than the Persons, or the property or assets of the Persons, so acquired; provided that, in the case of
Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that
the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in

Indebtedness or any agreement pursuant to which such Indebtedness was issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in such Indebtedness or agreement
and such encumbrance or restriction is not materially more disadvantageous to the holders of the Notes than is customary in comparable financings (as determined in good faith by the Company) and the Company determines that any such encumbrance or
restriction will not materially affect the any Issuer’s ability to make principal or interest payments on the Notes; and 
 (14) restrictions on the sale, lease or transfer of property or assets arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the

respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company shall not and shall not permit any of its Restricted Subsidiaries to issue any Disqualified Stock; provided, however, that the
Company, the Issuers and the Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Company’s Consolidated Leverage Ratio at the time of incurrence of such Indebtedness or the issuance of such
Disqualified Stock, as the case may be, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom as if the same had occurred at the end of the most recently ended four full fiscal quarter
period of the Company for which internal financial statements are available, would have been no greater than 3.0 to 1. 
 (b)
The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

 (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the
Company and any of its Restricted Subsidiaries; provided, however, that:

Notes, in the case of the Issuers, or the Note Guarantee, in the case of a Guarantor; and 
 (B)(i) any
subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a
Person that is not either the Company or a Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted

(ii) the Guarantee by Restricted Subsidiaries that are not Guarantors of Indebtedness of Restricted Subsidiaries that are not Guarantors to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this
covenant; 
 (10) the incurrence by the Company or any of the Restricted Subsidiaries of Indebtedness in respect
of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, performance, letter of credit or completion or performance and surety bonds in the ordinary course of business; 
 (11) the incurrence by either Issuer or any of the Restricted Subsidiaries of Indebtedness arising from the honoring by a

connection with an Asset Acquisition by either Issuer or any Guarantor or Australian Restricted Subsidiary, provided that such Indebtedness was in existence prior to the contemplation of such Persons becoming Subsidiary Guarantors or
Australian Restricted Subsidiaries or such merger or consolidation or such acquisition of property or Asset Acquisition, provided further that the ratio of the aggregate principal amount of such Indebtedness incurred with respect to any such
transaction to Consolidated EBITDA (for the most recent four-quarter period for which financial information is available) attributable to the Person or property so acquired pursuant to such transaction (as determined in good faith by the Company) is
2.5 to 1.0 or less (the “Acquisition Debt Ratio Test”), and: (A) such Indebtedness is subordinated in right of payment (and, if such Indebtedness is secured by Liens on any Collateral, subordinated in lien priority) to the
Notes in a manner substantially similar to the payment subordination (and lien subordination, as applicable) provisions applicable to the Second Lien Debt pursuant to the Intercreditor Agreement, and does

  

 73 








 
not mature prior to a date which is ninety-one (91) days following the final maturity date of the Notes; or (B) such Indebtedness is non-recourse to the Company and its Restricted

clauses (A) and (B) or any combination thereof complies with the Acquisition Debt Ratio Test at the time of incurrence and does not exceed (together with all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace,
defease or discharge any Indebtedness incurred pursuant to this clause (14)) $20.0 million in the aggregate at any one time outstanding; and 
 (15) the incurrence by the Company or any of the Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including
all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (15), not to exceed $10.0 million. 
 (c) The Company shall not incur, and shall not permit the Issuers or any other Guarantor to incur, any Indebtedness (including Permitted
Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company, the Issuers or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note
Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuers solely by virtue of being unsecured or by virtue
of being secured on junior priority basis or junior in right of distribution of collateral proceeds. 
 (d) For purposes of
determining compliance with this Section 4.09 and Section 4.12 hereof, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (15) of
Section 4.09(b) hereof, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company shall be permitted (in its sole discretion) to classify such item of Indebtedness on the date of its incurrence, or later reclassify all
or a portion of such item of Indebtedness, in any manner that complies with this covenant. Notwithstanding the foregoing, all Priority Lien Debt will be deemed to have been incurred in reliance on the exception provided by clause (1) of the
definition of Permitted Debt and all Parity Lien Debt outstanding on the date of this Indenture will be deemed to have been incurred in reliance on the exception provided by clause (3) of the definition of Permitted Debt. The accrual of
interest or preferred stock or Disqualified Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of
preferred stock or Disqualified Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or
Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual,
accretion or payment is included in Consolidated Interest of the Company as accrued. For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount
of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this Section 4.09, the
maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 (e) The amount of any Indebtedness outstanding as of any date will be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; 

 

 74 








 (2) the principal amount of the Indebtedness, in the case of any other
Indebtedness; and 
 (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the
specified Person, the lesser of: 
 (A) the Fair Market Value of such assets at the date of determination; and

 (B) the amount of the Indebtedness of the other Person. 
 Section 4.10 Asset Sales. 
 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) The Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at
least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; 
 (2) except in the case of a Permitted Asset Swap, at least 75% of the consideration received in the Asset Sale by the Company
or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash: 
 (A) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases the Company or such Restricted Subsidiary from or indemnifies against
further liability; 
 (B) any securities, notes or other obligations received by the Company or any such
Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 120 days after such Asset Sale, to the extent of the cash received in that conversion; and 
 (C) any stock or assets of the kind referred to in clauses (3) or (5) of paragraph (b) of this
Section 4.10; and 
 (3) subject to certain limitations, after the Refinancing Date in the case of an Asset
Sale that constitutes a Sale of Collateral, the Company (or the applicable Restricted Subsidiary, as the case may be) promptly deposits the Net Proceeds therefrom immediately upon receipt thereof as Collateral in an account or accounts (each, a
“Collateral Proceeds Account”) held by or under the control of (for purposes of the Uniform Commercial Code) or otherwise subject to a perfected security interest in favor of the applicable Collateral Trustee or its agent to secure,
to the extent the Collateral sold was U.S. Collateral, all U.S. Secured Obligations, and to the extent the Collateral Sold was Canadian Collateral, all Canadian Secured Obligations. 
  

 75 








 (b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale other than a
Sale of Collateral, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds, at its option: 
 (1) to repay, repurchase or redeem Priority Lien Obligations, if the Priority Lien Obligations repaid are revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

 (2) to repay, repurchase or redeem Parity Lien Obligations; provided, that the Issuers offer to repay,
repurchase or redeem the Notes on a pro rata basis; 
 (3) to acquire all or substantially all of the assets of,
or any Capital Stock of, another Permitted Business (provided that in the case of any such acquisition of Capital Stock, after giving effect thereto, the Permitted Business is or becomes a Restricted Subsidiary of the Company); 
 (4) to repay Indebtedness (other than Secured Obligations) that is secured by a Permitted Lien on any assets that were sold
in such Asset Sale; 
 (5) to make a capital expenditure; 
 (6) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted
Business; 
 (7) in the case of an Asset Sale (other than a sale of an asset that had constituted Collateral at
any time since the date of this Indenture) by a Restricted Subsidiary that is not a Guarantor, to repay, repurchase or redeem Indebtedness of the Company or any Restricted Subsidiary that is not contractually subordinated in right of payment to the
Notes; or 
 (8) any combination of the foregoing clauses (1) through (7). 
 (c) Within 365 days after the receipt of any Net Proceeds from a Sale of Collateral, the Company (or the applicable Restricted Subsidiary,
as the case may be) may apply such Net Proceeds, at its option: 
 (1) to purchase other assets that would
constitute Collateral; 
 (2) to acquire all or substantially all of the assets of, or any Capital Stock of, a
Permitted Business (provided that in the case of any such acquisition of Capital Stock, after giving effect thereto, the Permitted Business becomes a Guarantor or is merged into or consolidated with an Issuer or any Guarantor); 
 (3) to repay Indebtedness (other than Secured Obligations) that is secured by a Permitted Priority Lien on any Collateral
that was sold in such Asset Sale; 
 (4) to make a capital expenditure with respect to assets that constitute
Collateral; 
 (5) any combination of the foregoing clauses (1) through (4). 
 (d) In the case of clauses (3), (5) and (6) of paragraph (b) of this Section 4.10 and clauses (1), (2) and
(4) of paragraph (c) of this Section 4.10, the Company (or the applicable Restricted Subsidiary, as

  

 76 








 
the case may be) will be deemed to have complied with its obligations in paragraphs (a), (b) and (c) of this Section 4.10 if it enters into a binding commitment to acquire such
assets or Capital Stock prior to 360 days after the receipt of the applicable Net Proceeds; provided that such binding commitment will be subject only to customary conditions and such acquisition is completed within 180 days following the expiration
of the aforementioned 360 day period. If the acquisition contemplated by such binding commitment is not consummated on or before such 180th day, and the Company (or the applicable Restricted Subsidiary, as the case may be) has not applied the
applicable Net Proceeds for another purpose permitted by the applicable paragraph (a), (b) or (c) of this Section 4.10 on or before such 180th day, such commitment shall be deemed not to have been a permitted application of Net
Proceeds. 
 (e) Pending the final application of any Net Proceeds of an Asset Sale, other than a Sale of Collateral, the
Company (or the applicable Restricted Subsidiary) may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 
 (f) Any Net Proceeds from Asset Sales that are not applied or invested as provided in paragraph (b) or (c) of this
Section 4.10 constitute “Excess Proceeds.” 
 (g) When the aggregate amount of Excess Proceeds exceeds
$15.0 million, within forty-five (45) days thereof, the Issuers will make a joint offer (an “Asset Sale Offer”) to all Holders and all holders of other Parity Lien Debt 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 in accordance with Section 3.08 hereof to purchase, prepay or redeem the maximum principal amount of Notes as Units and such other Parity Lien
Debt (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset
Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest to the date of purchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant
interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes as Units and Parity Lien Debt tendered into (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the trustee will select the Notes as Units and such other
Parity Lien Debt to be purchased on a pro rata basis, based on the amounts tendered or required to be prepaid or redeemed. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder
to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to a Change of Control Offer or an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with
the Change of Control or Asset Sale provisions of this Section 3.08 hereof or this Section 4.10, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under
Section 3.08 hereof or this Section 4.10 by virtue of such compliance.

the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”), unless:

Person; and 
  

 77 








 (2) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration

 (1) any employment or consulting agreement, employee benefit plan, stock option or stock ownership plan, officer or director
indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments and issuances of Capital Stock, options, warrants or other rights to acquire
Capital Stock, in each case, pursuant thereto (provided that issuances of Capital Stock of Restricted Subsidiaries of the Company shall be limited to Voting Stock (in each case, representing an aggregate of not more than 5.0% of the fully
diluted Voting Stock of such Restricted Subsidiary) of not more than two Restricted Subsidiaries identified by the Company in an Officers’ Certificate delivered to the Trustee); 
 (2) transactions between or among the Company and/or its Restricted Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company
solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 
 (4) payment of reasonable and customary fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise) of Officers, directors, employees or consultants of the Company or any of its

Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and 
 (2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided,
however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries if the Board of Directors of the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 
 Section 4.15 Offer to Repurchase Upon Change of Control. 
 (a) If a Change of Control occurs, each Holder will have the right to require the Issuers to jointly repurchase all or any part of that
Holder’s Notes as Units (if prior to a Separation Event, equal to $2,000 or an integral multiple of $1,000 in excess thereof) pursuant to this Section 4.15 (a “Change of Control Offer”). Any such repurchase of the Notes
shall include the U.S. Notes and the Canadian Notes on a pro rata basis based on the aggregate principal amount of the Notes outstanding at the time of repurchase. In the Change of Control Offer, the Issuers will jointly offer the Holders a purchase
price in cash equal to 101% of the aggregate principal amount of Notes repurchased as Units, plus accrued and unpaid interest, if any, on the Notes repurchased 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 (the “Change of Control Payment”). Within fifteen (15) days following any Change of Control, the Issuers will mail a notice to each Holder describing the transaction or
transactions that constitute the Change of Control and stating: 
 (1) that the Change of Control Offer is being
made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

 79 








 (4) that, unless the Issuers default in the payment of the Change of Control
Payment, any Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase”
attached to the Notes completed, or transfer a beneficial interest in the Notes by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of
Control Payment Date; 
 (6) that Holders will be entitled to withdraw their election if the Paying Agent

for purchase, the serial number for Notes held in definitive form and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered, which unpurchased portion, if prior to a Separation Event, must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof. 
 The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder

Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance. 
 (b) On the Change of Control Payment Date, the Issuers will jointly, to the extent lawful: 
 (1) accept for payment all Notes or portions of Notes properly tendered as Units pursuant to the Change of Control Offer;

 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or
portions of Notes properly tendered as Units; and 
 (3) deliver or cause to be delivered to the Trustee the
Notes properly accepted together with an Officers’ Certificate of each Issuer stating the aggregate principal amount of Notes or portions of Notes as Units being purchased by the Issuers. 
 (c) The Paying Agent will promptly mail to each Holder properly tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Issuers will jointly publicly announce the results of the
Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 
 (d) The Issuers will not be
required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and
purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been

  

 80 








 
given pursuant to Section 3.01(a) through 3.01(c) hereof, unless and until there is a default in payment of the applicable redemption price. 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 Payments for Consent. 
 The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders
that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.17 Additional Note Guarantees. 
 (a) If the Company or any of
its Restricted Subsidiaries acquires or creates another Domestic Subsidiary after the date of this Indenture or a Restricted Subsidiary that was not a Domestic Subsidiary on the date of this Indenture becomes a Domestic Subsidiary, then that
Domestic Subsidiary will become a U.S. Guarantor and execute a supplemental indenture in the form attached hereto as Exhibit F-1 and deliver an opinion of counsel satisfactory to the Trustee within thirty (30) Business Days of the date on which
it was acquired or created. 
 (b) If the Canadian Issuer or any of its Restricted Subsidiaries acquires or creates another
Canadian Subsidiary after the date of this Indenture, then that Canadian Subsidiary will become a Canadian Guarantor and execute a supplemental indenture in the form attached hereto as Exhibit F-2 and deliver an opinion of counsel satisfactory to
the Trustee within thirty (30) Business Days of the date on which it was acquired or created. 
 Section 4.18
Designation of Restricted and Unrestricted Subsidiaries. 
 The Board of Directors of the Company may designate any
Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default; provided that in no event shall the business currently operated by the Canadian Issuer be transferred to or held by an Unrestricted
Subsidiary. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary and has assets of more than $1,000, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the
Subsidiary designated as Unrestricted shall be deemed to be an Investment made as of the time of the designation and shall reduce the amount available for Restricted Payments under Section 4.07 hereof or under one or more clauses of the
definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default. 
 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary shall 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 of the Company certifying that such designation complied with the preceding conditions and was permitted by
Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any
Indebtedness

  

 81 








 
of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under
Section 4.09 hereof, the Company shall be in default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such
designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is
permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be in existence following such
designation. 
 Section 4.19 Additional Amounts. 
 (a) All payments made by an Issuer, any Guarantor or a Surviving Entity as well as all payments made by a Trustee pursuant Article 8 or
Article 11 hereof (each a “Payor”) under or with respect to the Notes will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other
governmental charge imposed or levied by or on behalf of Canada or any subdivision thereof or by any authority or agency therein or thereof having power to tax (hereinafter “Taxes”) unless such Payor is required to withhold or
deduct Taxes by law or by the interpretation or administration thereof. If a Payor is so required to withhold or deduct any amount of interest for or on account of Taxes from any payment made under or with respect to the Notes such Payor will pay
such additional amounts of interest (“Additional Amounts”) as may be necessary such that the net amount received in respect of such payment by each holder (including Additional Amounts) after such withholding or deduction will not
be less than the amount the holder would have received if such Taxes had not been required to be so withheld or deducted; provided that no Additional Amounts will be payable with respect to a payment made to a holder (an “Excluded
Holder”) (i) with which the Payor or the Canadian Issuer does not deal at arm’s length (for the purpose of the Income Tax Act (Canada)) at the time of making such payment (ii) which is subject to such Taxes by reason of the
holder being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some connection with, Canada or any province or territory thereof, otherwise than by
the mere holding of debt securities or the receipt of payments thereunder, or (iii) which is subject to such Taxes by reason of the holder’s failure to comply with any certification, identification, information, documentation or other
reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Taxes. Each Payor will also
(i) make such withholding or deduction and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Payor will furnish to the holders of the Units, within thirty (30) days after
the date the payment of any Taxes is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by such Payor. The Issuers will indemnify and hold harmless each holder (other than all Excluded Holders) for the amount of
(i) any Taxes not withheld or deducted by a Payor and levied or imposed and paid by such holder as a result of payments made under or with respect to the Notes, (ii) any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, and (iii) any Taxes imposed with respect to any reimbursement under clauses (i) or (ii) above. 
 (b) At least thirty (30) days prior to each date on which any payment under or with respect to the Notes is due and payable, if a Payor is aware that it will be obligated to pay Additional Amounts
with respect to such payment, such Payor will deliver to the Trustee an Officers’ Certificate stating the fact that such Additional Amounts will be payable, the amounts so payable and will set forth such other information necessary to enable
the Trustee to pay such Additional Amounts to holders on the payment date. Whenever in this Indenture there is mentioned, in any context, the payment of principal (and premium, if any), interest or any other amount payable under or with respect to
any Note, such mention

  

 82 








 
shall be deemed to include mention of the payment of Additional Amounts provided for in this section to the extent that, in such context, Additional Amounts are, were or would be payable in
respect thereof. 
 Section 4.20 Excess Cash Flow Offer. 
 (a) If the Company and its Restricted Subsidiaries have Excess Cash Flow for any fiscal year commencing with the fiscal year ending
December 31, 2010 (the “Relevant Fiscal Year”), then the Issuers shall jointly apply an amount (the “Excess Cash Flow Offer Amount”) equal to 50% of such Excess Cash Flow for such period to make a joint offer
to the Holders to repurchase all or a portion of their Notes as Units with an aggregate repurchase price in cash equal to the Excess Cash Flow Offer Amount pursuant to and subject to the conditions contained in this Indenture (an “Excess
Cash Flow Offer”). 
 (b) Within 110 days after the end of any fiscal year with respect to which the Issuers are
required to make an Excess Cash Flow Offer pursuant to Section 4.20(c) hereof, the Issuers must send, by registered first-class mail an offer to each Holder, with a copy to the Trustee, which offer shall govern the terms of the Excess Cash Flow
Offer. Such offer shall state: 
 (1) that the Excess Cash Flow Offer is being made pursuant to this
Section 4.20; 
 (2) the Excess Cash Flow Offer Amount and the date on which payment in respect of the
Excess Cash Flow Offer will be made by the Issuers (the “Excess Cash Flow Offer Payment Date”), which shall be not less than thirty (30) and not more than sixty (60) days from the date such notice is mailed, other than as
may be required by law; 
 (3) that any Notes not tendered or accepted for payment shall continue to accrue
interest; 
 (4) that, unless the Issuers default in making such payment, any Notes as Units accepted for payment
pursuant to the Excess Cash Flow Offer shall cease to accrue interest after the Excess Cash Flow Offer Payment Date; 
 (5) that if only a portion of a Note is purchased pursuant to an Excess Cash Flow Offer, a new Note in a principal amount equal to the portion thereof not purchased will be issued in the name of the Holder thereof upon cancellation of the
original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made), and that Notes (or portions thereof) purchased pursuant to an Excess Cash Flow Offer will be cancelled and cannot be reissued;

 (6) that Holders electing to have a Note purchased pursuant to such Excess Cash Flow Offer shall be required
to surrender the Security, with the form entitled “Option of Holder To Elect Purchase” on the reverse of the Note completed, or transfer such Note by book-entry transfer, to the Issuers, a depositary, if appointed by the Issuers, or the
Paying Agent at the address specified in the notice at least three (3) Business Days before the Excess Cash Flow Offer Payment Date; and 
 (7) that Holders shall be entitled to withdraw their election if the Issuers, the depositary or the Paying Agent, as the case may be, receives, not later than the Excess Cash Flow Payment Date, a notice
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. 
  

 83 








 (c) With respect to each Excess Cash Flow Offer, the Issuers shall be entitled to reduce the
applicable Excess Cash Flow Offer Amount with respect thereto by an amount equal to the sum of (x) the aggregate repurchase price paid for any Notes theretofore repurchased by the Issuers in the open market or privately negotiated transaction
(and, in each case, cancelled by the Issuers) and (y) the aggregate redemption price paid for any Notes theretofore redeemed pursuant to one or more optional redemptions, in each case, prior to making such Excess Cash Flow Offer;
provided, however, that the repurchase or redemption of such Notes would then not be considered in connection with calculating the amount of Excess Cash Flow for the next period. For the avoidance of doubt, the Issuers shall not be entitled
to reduce the applicable Excess Cash Flow Offer Amount by the aggregate repurchase price of any Notes theretofore repurchased by the Issuers pursuant to any Asset Sale Offers, Change of Control Offers or Excess Cash Flow Offers during such period.
If the aggregate repurchase price of Notes tendered pursuant to any Excess Cash Flow Offer is less than the applicable Excess Cash Flow Offer Amount, the Company may, subject to the other provisions of this Indenture, use any such Excess Cash Flow
for any other lawful purpose 
 (d) In each Excess Cash Flow Offer, the Issuers will be required to repurchase Notes as Units
(if prior to a Separation Event, equal to $2,000 or an integral multiple of $1,000 in excess thereof) validly tendered in response to such Excess Cash Flow Offer at a purchase price in cash equal to 100% of their principal amount (without premium),
plus accrued but unpaid interest thereon to the Excess Cash Flow Offer Payment Date, in accordance with the procedures set forth in this Indenture. If the aggregate principal amount of Notes tendered into such Excess Cash Flow Offer exceeds the
Excess Cash Flow Offer Amount, the Trustee will select the Notes to be purchased as Units on a pro rata basis. 
 (e)
Notwithstanding the foregoing provisions of this Section 4.20, the Issuers will not be required (but may elect to do so) to make an Excess Cash Flow Offer in accordance with this Section 4.20 unless the Excess Cash Flow Offer Amount with
respect to the applicable period in respect of which such Excess Cash Flow Offer is to be made exceeds $2.5 million (with lesser amounts being carried forward for purposes of determining whether the $2.5 million threshold has been met for any future
period). Upon completion of each Excess Cash Flow Offer, the Excess Cash Flow Offer Amount will be reset at zero. 
 (f) The
Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to an
Excess Cash Flow Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.20, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have
breached their obligations under this Section 4.20 by virtue thereof.

 88

described in clause (5) of Section 6.01 hereof have rescinded the declaration of acceleration in respect of such Indebtedness within thirty (30) days of the date of such declaration; provided that (1) the annulment of the

however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted in such acceleration. Upon any such waiver,
such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon. 
 Section 6.05 Control by Majority. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be
unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability. In addition, the Trustee may withhold from Holders notice of any continuing Default or Event of Default if it

  

 89 








 
determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest or premium, if any. 
 Section 6.06 Limitation on Suits. 
 (a) Subject to the provisions of Article 7 hereof, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this

interest or premium, if any, when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) such Holder has previously given the Trustee notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to 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 sixty (60) days after the receipt of the
request and the offer of security or indemnity; and 
 (5) Holders of a majority in aggregate principal amount of
the then outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period. 
 (b) A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, or premium or
interest, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder; provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry
of judgment therein would, under applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien. 
 Section 6.08 Collection Suit by Trustee. 
 If an Event of Default
specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, or premium or
interest, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection and the reasonable compensation,
expenses, disbursements and advances of the Trustee and its agents and counsel.

any other obligor upon the Notes), their creditors or their property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements, advances and any other amounts due to the Trustee and its agents and counsel and any other amounts due to the Trustee under Section 7.06 hereof. To the extent that the payment of any such
compensation, expenses, disbursements, advances and any other amounts due to the Trustee and its agents and counsel and any other amounts due to the Trustee under Section 7.06 hereof out of the estate in any such proceeding, shall be denied for
any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in
liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities.

 Third: to the Issuers or the applicable Guarantor, as the case may be, its or their successors or assigns, or as a
court of competent jurisdiction shall direct.

other realization upon all or any part of the Canadian Collateral in connection with any foreclosure, collection or other enforcement of Liens granted to the Canadian Collateral Trustee in the Canadian Security Documents shall be applied pursuant to

omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by

reimburse each of the Trustee and each Collateral Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services, except for any such disbursement,

  

 94

loss, liability or expense shall be determined to have been caused by its own negligence or bad faith. Each of the Trustee and each Collateral Trustee will notify the Issuers promptly of any claim of which the Trustee has received written notice and
for which it may seek indemnity. Failure by the Trustee or either Collateral Trustee, as applicable, to so notify the Issuers will not relieve the Issuers or any of the Guarantors of their obligations hereunder. The Issuers or such Guarantor will
defend the claim and the Trustee and each Collateral Trustee, as applicable, will cooperate in the defense. The Trustee and either Collateral Trustee, as applicable, may have separate counsel and the Issuers shall pay the reasonable fees and

to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, or premium or 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(9) or
(10) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.09 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 Issuers. 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 that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.06 hereof. Notwithstanding replacement of the Trustee pursuant to this
Section 7.07, the Issuers’ obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee.

connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not
constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise
under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(8) hereof will not constitute Events of Default.

  

 97 








 Section 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance under Section 8.02 hereof or Covenant Defeasance under Section 8.03 hereof:

 (1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in
U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of
independent public accountants, to pay the principal of, or interest and premium, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Issuers must specify whether
the Notes are being defeased to such stated date for payment or to a particular redemption date; 
 (2) in the
case of Legal Defeasance under Section 8.02 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Issuers have received from, or there has been published by, each
of the Internal Revenue Service and the Canada Revenue Agency a ruling or (b) since the date of this Indenture, there has been a change in the applicable U.S. federal and Canadian income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal or Canadian income tax purposes as a result of such Legal Defeasance and will be subject to U.S.
federal and Canadian income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
 (3) in the case of Covenant Defeasance under Section 8.03 hereof, the Issuers must deliver to the Trustee an Opinion of
Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal or Canadian income tax purposes as a result of such Covenant Defeasance and will be subject to
U.S. federal and Canadian income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event
of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings); 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under,
any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which either Issuer or any of the Guarantors is a party or by which either Issuer or any
of the Guarantors is bound; 
 (6) the Issuers must deliver to the Trustee an Officers’ Certificate stating
that the deposit was not made by the Issuers with the intent of preferring the Holders of Notes over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuers or others; and

  

 98 








 (7) the Issuers must deliver to the Trustee an Officers’ Certificate
and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 (b) The Collateral will be released from the Liens securing the Notes in accordance with Section 12.04 hereof and the Security Documents, upon a Legal Defeasance or Covenant Defeasance in accordance
with this Article 8. 
 Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous
Provisions. 
 Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and
applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including either of the Issuers acting as Paying Agent) as the Trustee may determine, to the
applicable Holders of all sums due and to become due thereon in respect of principal, or premium or interest, if any, but such money need not be segregated from other funds except to the extent required by law. 
 The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuers from time to time
upon the joint request of the Issuers any money or non-callable Government Securities held by either of the Issuers as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to Issuers. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, or
premium or interest, if any, on any Note and remaining unclaimed for two years after such principal, or premium or interest, if any, has become due and payable shall be paid to the Issuers on their joint request or (if then held by either of the
Issuers) will be discharged from such trust; and the applicable Holder will thereafter be permitted to look only the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Issuers as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuers cause to be published once, in
the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than thirty (30) days from the date of such notification or
publication, any unclaimed balance of such money then remaining will be repaid to the Issuers. 
  

 99 








 Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02
or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this
Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuers make any payment of principal of, or premium or interest, if any, on any Note following the reinstatement of its obligations, the
Issuers will be subrogated to the rights of the applicable Holders to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders. 
 Notwithstanding Section 9.02 of this Indenture, without the consent of any Holder, the Issuers, the Guarantors, the Trustee and the applicable Collateral Trustee may amend or supplement this
Indenture, the Notes, the Note Guarantees and the Security Documents: 
 (1) to cure any ambiguity, defect or
inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

 (3) to provide for the assumption of an Issuer’s or a Guarantor’s obligations to Holders of Notes
and Note Guarantees by a successor to an Issuer’s or such Guarantor pursuant to Article 5 or Article 10 hereof; 
 (4) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights hereunder of any such Holder; 
 (5) to make, complete or confirm any grant of Collateral permitted or required by this Indenture or any Security Document or
to evidence the release, termination or discharge of any Collateral or Security Documents or Note Guarantees in accordance with the terms of this Indenture or the Security Documents; 
 (6) to conform the text of this Indenture, the Notes, the Note Guarantees or the Security Documents to any provision of the
“Description of Notes” section of the Offering Memorandum, 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 Notes, the Note Guarantees
or the Security Documents, which intent may be evidenced by an Officers’ Certificate of the applicable Issuer or Guarantor to that effect; 
 (7) to enter into additional or supplemental Security Documents or otherwise provide additional Collateral; 
 (8) to provide for the issuance of Additional Securities in accordance with the limitations set forth in this Indenture as of the date hereof; 
  

 100 








 (9) to allow any Guarantor to execute a supplemental indenture and/or a Note
Guarantee with respect to the Notes; 
 (10) to subordinate the Liens of the applicable Collateral Trustee on the
Collateral to Permitted Priority Liens; 
 (11) to evidence and provide for the acceptance of appointment
hereunder by a successor trustee pursuant to the requirements of this Indenture; or 
 (12) to provide for the
release of a Guarantee of the Notes by a Restricted Subsidiary of either Issuer which release is otherwise permitted under this Indenture and would not result in a Default or Event of Default. 
 Section 9.02 With Consent of Holders. 
 Except as provided below in this Section 9.02, the Issuers, the Guarantors, the Trustee and the applicable Collateral Trustee may amend or supplement this Indenture (including, without limitation,
Sections 3.08, 3.9, 4.10, 4.15 and 4.20 hereof), the Notes, the Note Guarantees or the Security Documents with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without
limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Units and/or Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, or premium or interest, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note
Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase
of, the Units and/or Notes). Section 2.08 hereof shall determine which Units are considered to be “outstanding” for purposes of this Section 9.02. 
 Upon the joint request of the Issuers accompanied by a resolution of their Boards of Directors authorizing the execution of any such amended
or supplemental indenture, and upon the filing with the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02
hereof, the Trustee will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under
this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 
 It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such
consent approves the substance thereof. 
 After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Issuers will mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to mail such notice, or any defect therein, will not, however, in any way impair or affect
the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of at least a majority in aggregate principal amount of the Notes then outstanding may waive compliance in a particular
instance by the Issuers and the Guarantors with any provision of this Indenture, the Notes, the Note Guarantees or the Security Documents. However, without the consent of each Holder of the Units affected, an amendment, supplement or waiver under
this Section 9.02 may not (with respect to any Units held by a non-consenting Holder): 
 (1) reduce the
principal amount of Units whose Holders must consent to an amendment, supplement or waiver; 
  

 101 








 (2) reduce the principal of or change the fixed maturity of any Note or
alter any of the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.08, 3.09, 4.10, 4.15 and 4.20 hereof); 
 (3) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the Notes (except
a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Units or a waiver of the payment default that resulted from such acceleration); 
 (5) make any Note payable in money other than that stated in the Notes; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of
Notes to receive payments of principal of, or interest or premium, if any, on the Notes; 
 (7) waive a
redemption payment with respect to any Note (other than a payment required by Sections 3.08, 3.09, 4.10, 4.15 or 4.20 hereof); 
 (8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or 
 (9) make any change in the preceding amendment and waiver provisions. 
 In addition, any amendment to, or waiver of, the provisions of this Indenture or any Security Document that has the
effect of releasing all or substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least 66 2
/3% in aggregate principal amount of the Units then outstanding. 
 Section 9.03 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note
that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee
receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 
 Section 9.04 Notation on or Exchange of Units and Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. Each Issuer in
exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
  


 102 








 Failure to make the appropriate notation or issue a new Note will not affect the validity
and effect of such amendment, supplement or waiver. 
 Section 9.05 Trustee and Collateral Trustees to Sign Amendments,
etc. 
 The Trustee (or applicable Collateral Trustee) will sign any amended or supplemental indenture authorized pursuant to
this Article 9 or any amendments under the Security Documents if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee (or applicable Collateral Trustee). The Issuers may not sign an
amended or supplemental indenture until the Board of Directors of each Issuer approves it. In executing any amended or supplemental indenture, the Trustee (or applicable Collateral Trustee) will be provided with and (subject to Section 7.01
hereof) will be fully protected in relying upon an Officers’ Certificate of each of the Issuers and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

 Section 9.06 Effect of Separation Event. 
 Upon the occurrence of a Separation Event, all references to Section 9.01, 9.02 and 9.03 to “Units” shall be deemed to refer
to “Notes.” 
 ARTICLE 10 
 NOTE GUARANTEES 
 Section 10.01 U.S. Guarantee. 
 (a) Subject to this Article 10, each of the U.S. Guarantors hereby, jointly and severally, unconditionally guarantees (each, a “U.S.
Note Guarantee”) to each Holder holding a U.S. 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 U.S. Notes or the
obligations of the U.S. Issuer hereunder or thereunder, that: 
 (1) the principal of, and interest and premium,
if any, on the U.S. Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and interest and premium, if any, on the U.S. Notes, if lawful, and all other
obligations of the U.S. Issuer to the Holders holding U.S. Notes or the Trustee under this Indenture will be promptly paid in full or performed, all in accordance with the terms of this Indenture and the U.S. Notes; and 
 (2) in case of any extension of time of payment or renewal of any U.S. 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. 
 (b) Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the U.S. Guarantors will be jointly and severally obligated to pay the same immediately. Each
U.S. Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (c) The U.S. Guarantors hereby
agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the U.S. Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder holding U.S.
Notes with respect to

  

 103 








 
any provisions hereof or thereof, the recovery of any judgment against the U.S. Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a U.S. Guarantor. Each U.S. Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the U.S. Issuer, any right to require a
proceeding first against the U.S. Issuer, protest, notice and all demands whatsoever and covenants that its U.S. Note Guarantee will not be discharged except by complete performance of the obligations contained in the U.S. Notes and this Indenture.

 (d) If any Holder holding a U.S. Note or the Trustee is required by any court or otherwise to return to the U.S. Issuer, the
U.S. Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the U.S. Issuer or the U.S. Guarantors, any amount paid by either to the Trustee or such Holder, the U.S. Note Guarantee, to the extent
theretofore discharged, will be reinstated in full force and effect. 
 (e) Each U.S. Guarantor agrees that it shall not be
entitled to any right of subrogation in relation to the Holders holding U.S. Notes in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each U.S. Guarantor further agrees that, as between the
U.S. Guarantors, on the one hand, and the Holders holding U.S. Notes 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 the U.S. Note
Guarantees, 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 U.S. Guarantors for the purpose of the U.S. Note Guarantee. The U.S. Guarantors will have the right to seek contribution from any
non-paying U.S. Guarantor so long as the exercise of such right does not impair the rights of the Holders holding U.S. Notes under the U.S. Note Guarantees. 
 Section 10.02 Canadian Guarantee. 
 (a) Subject to this Article 10,
each of the Company and the Canadian Guarantors hereby, jointly and severally, unconditionally guarantees (each, a “Canadian Note Guarantee”) to each Holder holding a Canadian 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 Canadian Notes or the obligations of the Canadian Issuer hereunder or thereunder, that: 
 (1) the principal of, premium on, if any, and interest, if any, on the Canadian Notes will be promptly paid in full when due,
whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and interest and premium, if any, on the Canadian Notes, if lawful, and all other obligations of the Canadian Issuer to the Holders holding
Canadian Notes or the Trustee under this Indenture will be promptly paid in full or performed, all in accordance with the terms of this Indenture and the Canadian Notes; and 
 (2) in case of any extension of time of payment or renewal of any Canadian 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 Company and the Canadian Guarantors will be jointly and severally obligated to pay the same
immediately. Each Canadian Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
  

 104 








 (b) The Company and the Canadian Guarantors hereby agree that their obligations hereunder
are unconditional, irrespective of the validity, regularity or enforceability of the Canadian Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder holding Canadian Notes with respect to any
provisions hereof or thereof, the recovery of any judgment against the Canadian Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of either of the Company or a
Canadian Guarantor. The Company and each Canadian Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Canadian Issuer, any right to require a proceeding
first against an Issuer, protest, notice and all demands whatsoever and covenants that its Canadian Note Guarantee will not be discharged except by complete performance of the obligations contained in the Canadian Notes and this Indenture.

 (c) If any Holder holding a Canadian Note or the Trustee is required by any court or otherwise to return to the Canadian
Issuer, the Company, the Canadian Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Canadian Issuer, the Company or the Canadian Guarantors, any amount paid by either to the Trustee or such
Holder, the Canadian Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 
 (d)
The Company and each Canadian Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders holding Canadian Notes in respect of any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. The Company and each Canadian Guarantor further agrees that, as between the Company and the Canadian Guarantors, on the one hand, and the Holders holding Canadian Notes 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 the Canadian Note Guarantees, 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 Company
and the Canadian Guarantors for the purpose of the Canadian Note Guarantees. The Company and the Canadian Guarantors will have the right to seek contribution from any non-paying Canadian Guarantor or the Company, as the case may be, so long as the
exercise of such right does not impair the rights of the Holders holding Canadian Notes under the Canadian Note Guarantee. 
 Section 10.03 Limitation on Guarantor Liability. 
 Each Guarantor, and by its acceptance of Units and/or
Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal, state, provincial or foreign law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that
the obligations of each such 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 Guarantor that are relevant under such laws, and after giving
effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor
under its Note Guarantee not constituting a fraudulent transfer or conveyance. 
  

 105 








 Section 10.04 Execution and Delivery of Note Guarantee. 
 To evidence its U.S. Note Guarantee set forth in Section 10.01 hereof, each U.S. Guarantor hereby agrees that a notation of such U.S.
Note Guarantee substantially in the form attached as Exhibit E1 hereto will be endorsed by an Officer of such U.S. Guarantor on each U.S. Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such U.S.
Guarantor by one of its Officers. 
 To evidence its Canadian Note Guarantee set forth in Section 10.02 hereof, the Company
and each Canadian Guarantor hereby agrees that a notation of such Canadian Note Guarantee substantially in the form attached as Exhibit E2 hereto will be endorsed by an Officer of the Company and such Canadian Guarantor on each Canadian Note
authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of the Company and such Canadian Guarantor by one of its Officers. 
 Each U.S. Guarantor hereby agrees that its U.S. Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each U.S. Note a
notation of such U.S. Note Guarantee. 
 The Company and each Canadian Guarantor hereby agrees that its Canadian Note Guarantee
set forth in Section 10.02 hereof will remain in full force and effect notwithstanding any failure to endorse on each Canadian Note a notation of such Canadian Note Guarantee. 
 If an Officer whose signature is on this Indenture or on a Note Guarantee no longer holds that office at the time the Trustee authenticates
the Note on which the Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless. 
 The delivery of any Note by
the Trustee, after the authentication thereof hereunder, will constitute due delivery of the applicable Note Guarantee set forth in this Indenture on behalf of the applicable Guarantors. Neither the Issuers not any Guarantor shall be required to
make a notation on the Notes to reflect any Note Guarantee or any such release, termination or discharge thereof. 
 In the
event that the Company or any of its Restricted Subsidiaries acquires or creates any Domestic Subsidiary after the date of this Indenture, if required by Section 4.17(a) hereof, the Company shall cause such Domestic Subsidiary to comply with
the provisions of Section 4.17(a) hereof and this Article 10, to the extent applicable. 
 In the event that the Canadian
Issuer or any of its Restricted Subsidiaries or 3082833 Nova Scotia Company acquires or creates any Canadian Subsidiary after the date of this Indenture, if required by Section 4.17(b) hereof, the Canadian Issuer shall cause such Canadian
Subsidiary to comply with provisions of Section 4.17(b) hereof and this Article 10, to the extent applicable. 
 Section 10.05 Guarantors May Consolidate, etc., on Certain Terms. 
 Except as otherwise provided in
Section 10.06 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge or amalgamate with or into (whether or not such Guarantor is the surviving Person) another Person, other
than the Company or another Guarantor, unless: 
 (1) immediately after giving effect to such transaction, no
Default or Event of Default exists; and 
  

 106 








 (2) either: 
 (a) (i) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such
consolidation or merger or amalgamation (the “Successor Guarantor”) assumes all the obligations of that Guarantor under its Note Guarantee, this Indenture, and the Security Documents pursuant to a supplemental indenture and
appropriate Security Documents satisfactory to the Trustee, (ii) the Successor Guarantor causes such amendments, supplements or other instruments to be executed, delivered, filed and recorded in such jurisdictions as may be required by
applicable law to preserve and protect the Liens under the applicable Security Documents on the Collateral owned by or transferred to the Successor Guarantor, together with such financing statements as may be required to perfect any security
interests in such Collateral which may be perfected by the filing of a financing statement under the Uniform Commercial Code of the relevant jurisdiction; (iii) the Collateral owned by or transferred to the Successor Guarantor shall:
(A) continue to constitute Collateral under this Indenture and the applicable Security Documents, (B) be subject to Liens in favor of the applicable Collateral Trustee for the benefit of the Holders and any other Parity Lien Indebtedness
or Priority Lien Indebtedness and (C) not be subject to any Lien other than Permitted Liens; and (iv) the property and assets of the Person which is merged or consolidated with or into the Successor Guarantor, to the extent that they are
property or assets of the types which would constitute Collateral under the applicable Security Documents, shall be treated as after-acquired property and the Successor Guarantor shall take such action as may be reasonably necessary to cause such
property and assets to be made subject to the Lien of the applicable Security Documents in the manner and to the extent required under this Indenture and the Security Documents; or 
 (b) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this
Indenture, including without limitation, Section 4.10 hereof. 
 In case of any such consolidation, merger, amalgamation,
sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the applicable Notes and the due and
punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a
Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the applicable Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the
Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such

 (3) the Canadian Issuer will, or will cause the applicable Canadian Guarantor to, deliver to the applicable Collateral
Trustee, with respect to each of the Canadian Premises, such filings, surveys (or any updates or affidavits that the title company may reasonably require as necessary to issue the title insurance policies referred to above), local counsel opinions,
landlord agreements and fixture filings, along with such other documents, instruments, certificates and agreements, as shall be necessary or as such Collateral Trustee and its counsel shall reasonably require to create, evidence or perfect a valid
and at least first-priority Lien on the property subject to each such Canadian Mortgage (subject to Permitted Liens). 
 From
and after the date hereof, if any U.S. Issuer or any U.S. Guarantor acquires any personal property which is of a type that would constitute U.S. Collateral under any U.S. Security Document, it will be required as soon as practicable after the
acquisition thereof, to execute and deliver such security instruments, financing statements, and Officers’ Certificates and opinions of counsel as are necessary or required under this Indenture or under any U.S. Security Document, or as may be

Document and to have such after-acquired property added to the U.S. Collateral, and thereupon all provisions of this Indenture relating to such U.S. Collateral shall be deemed to relate to such
after-acquired property to the same extent and with the same force and effect.

Document and to have such after-acquired property added to the Canadian Collateral, and thereupon all provisions of this Indenture relating to such Canadian Collateral shall be deemed to relate to such after-acquired property to the same extent and
with the same force and effect; provided that no such security interests, financing statements, certificates and opinions shall be required of the Canadian Issuer or any Canadian Guarantor if the Canadian Collateral Trustee already has a perfected
security interest in such personal property by virtue of existing Canadian Security Documents. 
 On or prior to the date on
which any other additional Secured Debt Documents are executed or the date on which any Priority Lien Debt, Junior Lien Debt or other Parity Lien Debt is incurred, in each case, in accordance with the terms of this Indenture and the other Secured

 Section 13.02 Certificate and Opinion as to Conditions Precedent. 
 Upon any request or application by an Issuer to the Trustee to take any action under this Indenture, such Issuer shall furnish to the
Trustee: 
 (1) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee (which
must include the statements set forth in Section 13.03 hereof) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; and

 (2) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which must include the
statements set forth in Section 13.03 hereof) stating that, in the opinion of such counsel, all such conditions precedent and covenants have been satisfied; provided, that no such Opinion of Counsel shall be required in connection with
the order by the Issuer to authenticate and deliver the Initial Notes constituting the Initial Units on the date hereof pursuant to Section 2.02 hereof. 
 Section 13.03 Statements Required in Certificate or Opinion. 
 Each
certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture must include: 
 (1) a statement that the Person making such certificate or opinion has read such covenant or condition; 
 (2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; 
 (3) a statement that, in the opinion of such Person, he or she has made such examination or investigation as is necessary to
enable him or her to express an informed opinion as to whether or not such covenant or condition has been satisfied; and 
 (4) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been satisfied; provided, that an issuer of an Opinion of Counsel can rely as to matters of fact
on an Officers’ Certificate or a certificate of a public official. 
 Section 13.04 Rules by Trustee and
Agents. 
 The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may

 Section 13.05 No Personal Liability of

 No past, present, or future director, officer, employee, incorporator or

of, or by reason of, such obligations or their creation. Each Holder by accepting a Unit and/or a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Units and the Notes. The waiver
may not be effective to waive liabilities under the federal securities laws, and it is the view of the SEC that such waiver is against public policy. 
  

 122 








 Section 13.06 Governing Law. 
 THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 
 Section 13.07 No Adverse Interpretation of Other Agreements. 
 This
Indenture may not be used to interpret any other indenture, loan or debt agreement of the Company or its Subsidiaries or of any other Person. Any such indenture, loan or debt agreement may not be used to interpret this Indenture. 
 Section 13.08 Successors. 
 All agreements of each of the Issuers in this Indenture and the Notes will bind its successors. All agreements of the Trustee and each Collateral Trustee in this Indenture will bind its successors. All
agreements of each Guarantor in this Indenture will bind its successors, except as otherwise provided in Section 10.06 hereof. 
 Section 13.09 Severability. 
 In case any provision in this Indenture or in the Units or the Notes is
invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby. 
 Section 13.10 Counterpart Originals. 
 The parties may sign any number
of copies or counterparts of this Indenture. Each signed copy or counterpart will be an original, but all of them together represent the same agreement. 
 Section 13.11 Table of Contents, Headings, etc. 
 The Table of
Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and will in no way modify or restrict any of the
terms or provisions hereof. 
 Section 13.12 Judgment Currency. 
 (1) If for the purpose of obtaining or enforcing judgement against the Canadian Issuer or a Canadian Guarantor in any court
in any jurisdiction, it becomes necessary to convert into any other currency (such other currency being hereinafter in this Section 13.12 referred to as the “Judgment Currency”) an amount due in Canadian or United States
dollars under this Indenture, the conversion will be made at the rate of exchange prevailing on the Business Day immediately preceding (i) the date of actual payment of the amount due, in the case of any proceeding in the courts of the Province
of Ontario or in the courts of any other jurisdiction that will give effect to such conversion being made on such date, or (ii) the date on which the judgement is given, in the case of any proceeding in the courts of any other jurisdiction (the
date as of which such conversion is made pursuant to this Section 13.12(1)(b) being hereinafter in this Section 13.12 referred to as the “Judgment Conversion Date”). 
  

 123 








 (2) If, in the case of any proceeding in the court of any jurisdiction
referred to in Section 13.12 (1)(b), there is a change in the rate of exchange prevailing between the Judgment Conversion Date and the date of actual payment of the amount due, the Borrower will pay such additional amount (and, if applicable,
such lesser amount) as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of Canadian dollars or United States dollars, as the
case may be, which could have been purchased with the amount of Judgment Currency stipulated in the judgement or judicial order at the rate of exchange prevailing on the Judgment Conversion Date. 
 (3) Any amount due from the Canadian Issuer or a Canadian Guarantor, as applicable, under the provisions of
Section 13.12 (2) will be due as a separate debt and will not be affected by judgement being obtained for any other amounts due under or in respect of this Indenture. 
 (4) The term “rate of exchange” in this Section 13.12 means: 
 (a) for a conversion of Canadian dollars to the Judgment Currency, the reciprocal of the official noon rate of exchange
published by the Bank of Canada for the date in question for the conversion of the Judgment Currency to Canadian dollars; 
 (b) for a conversion of United States dollars to the Judgment Currency when the Judgment Currency is Canadian dollars, the official noon rate of exchange published by the Bank of Canada for the date in
question for the conversion of United States dollars to Canadian dollars; 
 (c) if a required rate is not so
published by the Bank of Canada for any such date, the spot rate quoted by the Trustee at approximately noon (New York time) on that date in accordance with its normal practice for the applicable currency conversion in the wholesale market.

 Section 13.13 Interest Act (Canada). 
 For the purposes of this Indenture, whenever interest to be paid hereunder is to be calculated on the basis of 360 days or any other period
of time that is less than a calendar year, the yearly rate of interest to which the rate determined pursuant to such calculation is equivalent is the rate so determined multiplied by the actual number of days in the calendar year in which the same
is to be ascertained and divided by 360 or such other number of days in such period, as the case may be. 
 Section 13.14
Waiver of Jury Trial. 
 EACH OF THE ISSUERS THE GUARANTORS COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE UNITS, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 
 Section 13.15 Force Majeure. 
 In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its
control,

  

 124 








 
including, without limitation, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities or
communications services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

 [Insert the Global Security Legend, if
applicable pursuant to the provisions of the Indenture]

of the Indenture] 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below
unless otherwise indicated. 
 (1) INTEREST. Primus Telecommunications
Holding, Inc., a Delaware corporation (the “U.S. Issuer”), promises to pay or cause to be paid interest on the principal amount of this U.S. Note at 13.00% per annum. The U.S. Issuer will pay interest, if any, semi-annually in
arrears on June 15 and December 15 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 U.S. Notes will accrue from the most recent
date on which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if this U.S. 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 June 15, 2010. The U.S. 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 U.S. Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The U.S. Issuer will pay interest on the U.S. Notes (except defaulted interest), if any, to the Persons who are
registered Holders of U.S. Notes at the close of business on the June 1 or December 1 immediately preceding the Interest Payment Date, even if such U.S. 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 U.S. Notes will be payable as to principal, premium, if any, and 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 U.S. Issuer, payment of 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, if any, on all Global U.S. Notes and all other U.S. Notes the Holders of which will have provided wire transfer instructions to the U.S.
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,
The Bank of New York Mellon, the Trustee under the Indenture, will act as Paying Agent and Registrar. The U.S. Issuer may change the Paying Agent or Registrar without prior notice to the Holders of the U.S. Notes. The U.S. Issuer or any of its
Subsidiaries may act as Paying Agent or Registrar.

Computershare Trust Company of Canada, as Canadian Collateral Trustee. The terms of the U.S. Notes include those stated in the Indenture. The U.S. Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such
terms. To the extent any provision of this U.S. Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The U.S. Notes are secured obligations of the U.S. Issuer. The U.S. Notes
are secured by substantially all the assets of the U.S. Issuer and the applicable Guarantors pursuant to and as further described in the U.S. Security Documents referred to in the Indenture. Subject to Sections 2.02, 2.13, 4.09 and 4.12 thereof, the
Indenture does not limit the aggregate principal amount of U.S. Notes that may be issued thereunder. 
 (5)
OPTIONAL REDEMPTION. 
 (a) At any time prior to
December 15, 2012, the Issuers may, at their joint option, on any one or more occasions redeem up to 35% of the aggregate principal amount of their respective Notes issued under the Indenture as Units, upon not less than thirty (30) nor
more than sixty (60) days’ notice, at a redemption price equal to 113% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of Holders of Notes on the
relevant record date to receive interest on the relevant interest payment date) with the net cash proceeds of an Equity Offering by the Company; provided that:

the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 
 (B) the redemption occurs within sixty (60) days of the date of the closing of such Equity Offering. 
 (b) At any time prior to December 15, 2013, the Issuers may, at their joint option, on any one or more occasions redeem all or a part of the Notes as Units, upon not less than thirty (30) nor more than sixty (60) days’

and paragraph (7) below, the Notes will not be redeemable at the Issuers’ option prior to December 15, 2013. 
 (d) On or after December 15, 2013, the Issuers may, at their joint option, on any one or more occasions redeem all or a part of the Notes as Units, upon not less than thirty (30) nor more than
sixty (60) days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest on the Notes redeemed, to the applicable date of redemption, if redeemed during the
twelve-month period beginning on December 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant interest payment date:

 A1-3 








 Unless an Issuer defaults in the payment of the redemption price, interest will cease to
accrue on the U.S. Notes or portions thereof called for redemption on the applicable redemption date. 
 (6)
MANDATORY REDEMPTION. If the Second Lien Debt has not been repurchased, redeemed, defeased, refinanced or otherwise retired in accordance with the terms of this Indenture on or prior to
January 21, 2013, then the Issuers shall jointly issue an irrevocable notice of redemption on such date to jointly redeem all of the outstanding Notes as Units on February 19, 2013 at the applicable redemption price (expressed as
percentages of principal amount) set forth for such date, plus accrued and unpaid interest on the Notes redeemed, to the applicable date of redemption, under Section 3.01(c) of the Indenture, subject to the rights of Holders of Notes on the
relevant record date to receive interest on the relevant interest payment date. 
 (7)
REDEMPTION FOR CHANGES IN WITHHOLDING TAXES. If an Issuer or Guarantor has become or would become obligated to pay on the next date on which any amount
would be payable to a Holder under or with respect to the Notes, any Additional Amounts as a result of any change or amendment to the laws (or regulations promulgated thereunder) of Canada (or any subdivision thereof or by any authority or agency
therein or thereof having power to tax), or any change in or amendment to any official position or administration or assessing practices regarding the application or interpretation of such laws or regulations, which change or amendment is announced

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below
unless otherwise indicated. 
 (1) INTEREST. Primus Telecommunications
Canada Inc., an Ontario, Canada corporation (the “Canadian Issuer”), promises to pay or cause to be paid interest on the principal amount of this Canadian Note at 13.00% per annum. The Canadian Issuer will pay interest, if any,
semi-annually in arrears on June 15 and December 15 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 Canadian Notes will accrue
from the most recent date on which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if this Canadian 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 June 15, 2010. The Canadian 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 Canadian Notes to the extent lawful; it will pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Canadian Issuer will pay
interest on the Canadian Notes (except defaulted interest), if any, to the Persons who are registered Holders of Canadian Notes at the close of business on the June 1 or December 1 immediately preceding the Interest Payment Date, even if
such Canadian 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 Canadian Notes will be payable as to principal,
premium, if any, and 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 Canadian Issuer, payment of 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, if any, on all Global Canadian
Notes and all other Canadian Notes the Holders of which will have provided wire transfer instructions to the Canadian 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, The Bank of New York Mellon, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Canadian Issuer may change the Paying Agent or Registrar without
prior notice to the Holders of the Canadian Notes. The Canadian Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

 To whom it may concern, 
 Reference is made to (i) that certain Intercreditor Agreement, dated

Primus Telecommunications IHC, Inc., U.S. Bank National Association, in its capacity as successor collateral agent for the First Lien Obligations (as defined in the Intercreditor Agreement) (in such capacity, the “First Lien Collateral
Agent”), and U.S. Bank National Association, as U.S. Collateral Trustee for the Second Lien Obligations (as defined in the Intercreditor Agreement) (in such capacity, the “Second Lien Collateral Agent”) and (ii) that
certain Indenture, dated as of December 22, 2009, by and among Holding, Primus Telecommunications Canada Inc., the guarantors party thereto, The Bank of New York Mellon, as trustee, First Lien Collateral Agent and Computershare Trust Company of

and used herein have the meanings given to them in the Intercreditor Agreement. 
 Under Section 5.6 of the Intercreditor Agreement, at any
time following an acceleration of the First Lien Obligations in accordance with the terms and conditions of the First Lien Loan Documents, the First Lien Claimholders shall offer the Second Lien Claimholders the option to purchase the entire
aggregate amount of outstanding First Lien Obligations at the price set forth in the Intercreditor Agreement (the “Purchase Right”). In accordance with the terms and conditions of the First Lien Loan Documents, the First Lien
Obligations have been accelerated. Consequently, U.S. Bank National Association, acting solely in its capacity as First Lien Collateral Agent under the First Lien Loan Documents and as required by the First Lien Indenture, will deliver on behalf of
the First Lien Claimholders the notice substantially in the form set forth as Exhibit H to the First Lien Indenture (the “Offer Notice”) to the Second Lien Collateral Agent, acting on behalf of the Second Lien Claimholders, on or

 Pursuant to Section 5.6 of the Intercreditor Agreement, the Second Lien Claimholders must irrevocably accept or reject the First Lien Claimholders’ offer within twenty (20) Business Days of
the receipt of the Offer Notice and the parties must endeavor to close promptly thereafter. In accordance with Section 8.8 of the Intercreditor Agreement, the Offer Notice shall be deemed to have been received by the Second Lien Claimholders

 If the Second Lien Claimholders accept the First Lien
Claimholders’ offer within the time period specified therein, the Purchase Right may be exercised pursuant to the form of acceptance attached to the Offer Notice or pursuant to documentation mutually acceptable to each of the First Lien
Collateral Agent and the Second Lien Collateral Agent. If the Second Lien Claimholders reject such offer (or do not so irrevocably accept such offer within the required timeframe), the First Lien Claimholders will have no further obligations
pursuant to Section 5.6 of the Intercreditor Agreement and may take any further actions in their sole discretion in accordance with the First Lien Loan Documents and the Intercreditor Agreement.

an Insolvency or Liquidation Proceeding, the holders of Parity Lien Obligations and the Parity Lien Representatives may take any

  

 J-27 








 
actions and exercise any and all rights that would be available to a holder of unsecured claims, including, without limitation, the commencement of Insolvency or Liquidation Proceedings against
the Canadian Issuer or any Canadian Guarantor in accordance with applicable law; provided, however, that, both before and during an Insolvency or Liquidation Proceeding, the holders of Parity Lien Obligations and the Parity Lien
Representatives may not take any of the actions prohibited under Section 2.5(b) (including the provisions described under clauses (1) through (5) of Section 2.5(b)) or oppose or contest any order that it has agreed not to oppose
or contest under clauses (1) through (4) of the preceding paragraph. 
 (b) The holders of Parity Lien
Obligations or any Parity Lien Representative will not file or prosecute in any Insolvency or Liquidation Proceeding any motion for adequate protection (or any comparable request for relief) based upon their interest in the Collateral under the
Parity Liens, except that: 
 (1) they may freely seek and obtain relief: (A) granting a junior Lien
co-extensive in all respects with, but subordinated (as set forth in Section 2.4) to, all Liens granted in the Insolvency or Liquidation Proceeding to, or for the benefit of, the holders of Priority Lien Obligations; or (B) in connection
with the confirmation of any plan of reorganization or similar dispositive restructuring plan; and 
 (2) they
may freely seek and obtain any relief upon a motion for adequate protection (or any comparable relief), without any condition or restriction whatsoever, at any time after the Discharge of Priority Lien Obligations. 
 SECTION 2.11 Collateral Shared Equally and Ratably within Class. The parties to this Agreement agree that the payment and
satisfaction of all of the Secured Obligations within each Class will be secured equally and ratably by the Liens established in favor of the Canadian Collateral Trustee for the benefit of the Secured Parties belonging to such Class. It is
understood and agreed that nothing in this Section 2.11 is intended to alter the priorities among Secured Parties belonging to different Classes as provided in Section 2.4. 
 SECTION 2.12 Purchase Option. 
 (a) Without prejudice to the enforcement of remedies of the Canadian Collateral Trustee and the holders of Priority Lien Obligations, each Priority Lien Representative and the holders of Priority Lien
Obligations agree that at any time during the 90 day period following the earliest of: 
 (1) a payment default
in respect of any Priority Lien Obligations; 
 (2) an acceleration of any Priority Lien Obligations; 

(3) any event of default in respect of any Priority Lien Obligations that has occurred and continued for a period for 90
days or more; 
 (4) an Act of Required Debtholders in respect of the Collateral to which holders of at least 25%
of the applicable Parity Lien Obligations shall have objected in a written notice to the Canadian Collateral Trustee, each Priority Lien Representative and each Parity Lien Representative; and 
  

 J-28 








 (5) the commencement of any Insolvency or Liquidation Proceeding 

(such 90 day period, the “Purchase Option Period”), the holders of any Parity Lien Obligations (or one or more of their Affiliates
or designees) will, upon written notice (with respect to clause (4) above, delivered by holders of at least 25% of the Parity Lien Obligations), in each case through their Parity Lien Representative, to the Canadian Issuer, the Canadian
Collateral Trustee and each Priority Lien Representative pursuant to Section 7.7 (a “Purchase Notice”), have the option to purchase the entire aggregate amount of then outstanding Priority Lien Obligations, for cash
consideration in immediately available funds, at par plus accrued interest plus any fees and out-of-pocket expenses that at such time are accrued and unpaid but would be, under the terms of the relevant Priority Lien Documents, reimbursable by the
Canadian Issuer, without warranty or representation or recourse, on a pro rata basis for cash consideration in immediately available funds or with respect to any Priority Lien Obligations that are Hedging Obligations at a price equal to the net
aggregate amount then owing to counterparties under such Hedge Agreements, including all amounts owing to the counterparties as a result of the termination (or early termination) thereof (collectively, the “Purchase Price”).
For the avoidance of doubt, the Purchase Price will exclude any commitment or other fees that would have become due and payable in respect of unfunded commitments under the relevant Priority Lien Documents. Within 5 Business Days after receipt of
the Purchase Notice, each Priority Lien Representative will deliver to the Canadian Collateral Trustee and the Canadian Issuer a statement of the amount of Priority Lien Debt and other Priority Lien Obligations then outstanding for which it is the
Priority Lien Representative, which statement will also include wire transfer information and the portion of the Purchase Price to be remitted to each holder of Priority Lien Obligations then outstanding for which it is the Priority Lien
Representative (the “Calculation Notice”). 
 (b) Within 5 Business Days after receipt
of the Calculation Notice, the Canadian Collateral Trustee will send a copy of the Calculation Notice to the Canadian Issuer and each Parity Lien Representative and will include a statement as to the aggregate principal amount of Priority Lien
Obligations that each holder of Parity Lien Obligations is entitled to purchase pursuant to this Section 2.12. Within 10 Business Days after receipt of the Calculation Notice and the information referenced in the immediately preceding sentence
by such holders of Parity Lien Obligations, each holder of Parity Lien Obligations (together with its respective Affiliates and designees, collectively, the “Purchasers”) shall deliver written notice to the
Canadian Collateral Trustee of its intent to exercise its purchase option hereunder, and such written notice shall constitute an irrevocable commitment from such Purchaser to purchase its pro rata share of the Priority Lien Obligations at the
Purchase Price. Any holder of Parity Lien Obligations who fails to deliver such notice (each, a “Declining Holder”) shall be deemed to have elected not to exercise its purchase option hereunder, and the Canadian Collateral
Trustee shall promptly following such 10 Business Day period allocate, in a written notice to the remaining Purchasers, each Declining Holder’s pro rata share of the Priority Lien Obligations ratably among the remaining Purchasers (the
“Accepting Holders”). Upon receipt of notice from the Canadian Collateral Trustee of an allocation of additional Priority Lien Obligations, each Accepting Holder shall deliver written notice to the Canadian Collateral Trustee
of its intent to exercise its purchase option hereunder with respect to such additional Priority Lien Obligations. Any holder of Parity Lien Obligations who fails to deliver such notice within 10 Business Days after receipt shall be deemed not to
exercise its purchase option hereunder with respect to such additional Priority Lien Obligations. Following such 10 Business Day period, to the extent that any Priority Lien Obligations have not been elected for purchase, the Canadian Collateral
Trustee shall offer each Accepting Holder the option to purchase any such remaining Priority Lien Obligations on a pro

  

 J-29 








 
rata basis. If not all remaining Priority Lien Obligations are elected for purchase by the Accepting Holders on a pro rata basis, the Canadian Collateral Trustee may then offer the Accepting
Holders the opportunity to purchase more than a pro rata allocation of Priority Lien Obligations, so long as no other holder of Parity Lien Obligations shall have object to such non-pro rata allocation. 
 (c) On the date specified by the Canadian Collateral Trustee on behalf of the Purchasers (such date, the “Purchase
Date”), the holders of the Priority Lien Obligations shall sell to the Purchasers all (but not less than all) of the Priority Lien Obligations that are outstanding on the Purchase Date at the Purchase Price, subject to (i) any
required approval of any court or other regulatory or governmental authority then in effect and (ii) compliance with all other applicable laws. Upon the sale of the Priority Lien Obligations to the Purchasers, all commitments to fund any
purchased Priority Lien Obligations will automatically terminate, and Canadian Issuer hereby consents to such termination. 
 (d) The Purchase Price shall be remitted by wire transfer in federal funds to such bank accounts of the Priority Lien Representatives set forth in the Calculation Notice. Interest shall be calculated to
but excluding the Business Day on which such sale occurs if the amounts so paid by the Canadian Collateral Trustee and holders of the Parity Lien Obligations to the bank accounts designated by the Priority Lien Representatives are received in such
bank accounts prior to 12:00 p.m., New York City time, and interest shall be calculated to and including such Business Day if the amounts so paid by the Canadian Collateral Trustee and holders of the Parity Lien Obligations to the bank accounts
designated by the Priority Lien Representatives are received in such bank accounts later than 12:00 p.m., New York City time. 
 (e) The sale of the Priority Lien Obligations shall be expressly made without warranty or representation of any kind by the Priority Lien Representatives and the holders of Priority Lien Obligations as to
the Priority Lien Obligations, the Collateral or otherwise and without recourse to the Priority Lien Representatives and the holders of Priority Lien Obligations, except that each of the Priority Lien Representatives and the holders of Priority Lien
Obligations shall represent and warrant severally as to the Priority Lien Obligations then owing to it: (i) the amount of the Priority Lien Obligations being purchased as reflected in the books and records of the Priority Lien Representatives
or such holders of Priority Lien Obligations (but without representation or warranty as to the collectability, validity or enforceability thereof); (ii) that the Priority Lien Representatives and such holders of the Priority Lien Obligations
own the Priority Lien Obligations and are transferring the Priority Lien Obligations free and clear of any liens or encumbrances; and (iii) the Priority Lien Representatives and such holders of the Priority Lien Obligations have the right to
sell the Priority Lien Obligations and the sale is duly authorized. 
 (f) On the Purchase Date, each Purchaser
shall execute an assignment agreement in form and substance reasonably satisfactory to each Priority Lien Representative and each Parity Lien Representative in order to effect the sale of the Priority Lien Obligations to such Purchaser (and Canadian
Issuer hereby consents to such assignment and sale). After such sale becomes effective, the Priority Lien Obligations will remain outstanding and enforceable and will remain secured by the Priority Liens upon the Collateral in accordance with the
applicable provisions of the Priority Lien Documents as in effect at the time of such sale, and the Purchasers thereof will be entitled to the benefit of the Priority Liens upon the Collateral and sharing rights in the proceeds thereof in accordance
with the provisions of the Priority Lien Documents and this Agreement as in effect at the time of such sale, as fully as if the sale of the Priority Lien Debt had not been made. 
  

 J-30 








 (g) Notwithstanding the foregoing, following the purchase of the entire
aggregate amount of the Priority Lien Obligations by the holders of Parity Lien Obligations (or their Affiliates or designees), such holders of Parity Lien Obligations will have no further obligation to fund any commitments in respect of any
Priority Lien Obligations so purchased and all outstanding commitments in respect of any Priority Lien Obligations will automatically terminate. 
 (h) In no event will the Canadian Issuer or any Canadian Guarantor or any of their respective Affiliates have the option to purchase any Priority Lien Obligations pursuant to this Section 2.12.
Notwithstanding the foregoing, upon receipt of a Purchase Notice, the Canadian Issuer may, within 5 Business Days, notify the Canadian Collateral Trustee, the Priority Lien Representative and each Parity Lien Representative that it will, within 30
days of the date of the Purchase Notice, repay all amounts outstanding under any Priority Lien Obligations and terminate all commitments in respect thereof. For the duration of such 30 day period, no holder of any Parity Lien Obligations will take
any action in respect of this Section 2.12; provided, that if the Canadian Issuer does not repay all amounts outstanding under any Priority Lien Obligations and terminate all commitments in respect thereof within such 30 day period, the
holders of Parity Lien Obligations may, following such 30 day period, take any and all actions described in this Section 2.12. 
 (i) Neither the Canadian Collateral Trustee, any Priority Lien Representative nor any holder of Priority Lien Obligations will take any action with respect to the Collateral nor exercise any right or
remedy available under the Priority Lien Documents (including any action to accelerate the Priority Lien Debt) during the period following the receipt of a Purchase Notice until the end of the Purchase Option Period, including, without limitation
during the 30 day period set forth in Section 2.12(h).

nonappealable order or judgment of a court of competent jurisdiction; or

 J-32 








 SECTION 3.3 Enforcement of Liens. If the Canadian Collateral Trustee at any time
receives written notice that any event has occurred that constitutes a default or event of default under any Secured Debt Document entitling the Canadian Collateral Trustee to foreclose upon, collect or otherwise enforce its Liens hereunder, the

advisable and in the best interest of the holders of Secured Obligations. 
 SECTION 3.4 Application of Proceeds.

 (a) If any Collateral is sold or otherwise realized upon by the Canadian Collateral Trustee in connection with

sufficient to pay in full in cash all outstanding Priority Lien Debt and all other Priority Lien Obligations (other than any indemnification or other contingent liabilities in respect of which no claim or demand for payment has been made at such
time) that are then due and payable (including all interest accrued thereon after the commencement of any Insolvency or Liquidation Proceeding at the rate, including any applicable post-default rate, specified in the Priority Lien Documents, even if

rate, specified in the Parity Lien Documents, even if such interest is not enforceable, allowable or allowed as a claim in such proceeding, and including the discharge or cash collateralization (at the lower of (1) 101% of the aggregate undrawn

 FIFTH, any surplus remaining after the payment in full in cash of the amounts described in the preceding clauses will be paid
to the Canadian Issuer or the applicable Canadian Guarantor, as the case may be, its successors or assigns, or as a court of competent jurisdiction may direct. 
 (b) If any Parity Lien Representative or any holder of a Parity Lien Obligation collects or receives any proceeds of such
foreclosure, collection or other enforcement that should have been applied to the payment of the Priority Lien Obligations in accordance with Section 3.4(a) above, whether after the commencement of an Insolvency or Liquidation Proceeding or
otherwise, such Parity Lien Representative or holder of a Parity Lien Obligation, as the case may be, will forthwith deliver the same to the Canadian Collateral Trustee, for the account of the holders of the Priority Lien Obligations, to be applied
in accordance with Section 3.4(a). Until so delivered, such proceeds will be held by that Parity Lien Representative or that holder of a Parity Lien Obligation, as the case may be, for the benefit of the holders of the Priority Lien

 (b) No Secured Debt Representative or holder of Secured Obligations will have any liability whatsoever for any act or
omission of the Canadian Collateral Trustee. 
 SECTION 3.6 Documents and Communications. The Canadian Collateral Trustee
will permit each Secured Debt Representative and each holder of Secured Obligations upon reasonable

  

 J-34 








 
written notice from time to time to inspect and copy, at the cost and expense of the party requesting such copies, any and all Security Documents and other documents, notices, certificates,
instructions or communications received by the Canadian Collateral Trustee in its capacity as such. 
 SECTION 3.7 For Sole
and Exclusive Benefit of Holders of Secured Obligations. The Canadian Collateral Trustee will accept, hold, administer and enforce all Liens on the Collateral at any time transferred or delivered to it and all other interests, rights, powers and
remedies at any time granted to or enforceable by the Canadian Collateral Trustee and all other property of the Trust Estates solely and exclusively for the benefit of the present and future holders of present and future Secured Obligations, and
will distribute all proceeds received by it in realization thereon or from enforcement thereof solely and exclusively pursuant to the provisions of Section 3.4. 
 SECTION 3.8 Additional Secured Debt. 
 (a) The Canadian
Collateral Trustee will, as trustee hereunder, perform its undertakings set forth in Section 3.1(a) with respect to each holder of Secured Obligations of a Series of Secured Debt that is issued or incurred after the date hereof that:

 (1) holds Secured Obligations that are identified as Parity Lien Debt or Priority Lien Debt in accordance with
the procedures set forth in Section 3.8(b); and 
 (2) signs, through its designated Secured Debt
Representative identified pursuant to Section 3.8(b), a Collateral Trust Joinder and delivers the same to the Canadian Collateral Trustee. 
 (b) The Canadian Issuer will be permitted to designate as an additional holder of Secured Obligations hereunder each Person who is, or who becomes, the registered holder of Parity Lien Debt or the
registered holder of Priority Lien Debt incurred by the Canadian Issuer or any other Canadian Guarantor after the date of this Agreement in accordance with the terms of all applicable Secured Debt Documents. The Canadian Issuer may only effect such
designation by delivering to the Canadian Collateral Trustee an Additional Secured Debt Designation stating that: 
 (1) the Canadian Issuer or such other Canadian Guarantor intends to incur additional Secured Debt (“Additional Secured Debt”) which will either be (i) Priority Lien Debt permitted by each
applicable Secured Debt Document to be secured by a Priority Lien equally and ratably with all previously existing and future Priority Lien Debt, or (ii) Parity Lien Debt permitted by each applicable Secured Debt Document to be secured with a
Parity Lien equally and ratably with all previously existing and future Parity Lien Debt; 
 (2) specifying the
name and address of the Secured Debt Representative for such series of Additional Secured Debt for purposes of Section 7.7; 
 (3) the Canadian Issuer and each other Canadian Guarantor has duly authorized, executed (if applicable) and recorded (or caused to be recorded) in each appropriate governmental office all relevant
agreements, documents, filings and recordations to ensure that the Additional Secured Debt is secured by the Collateral in accordance with the Security Documents; 
  

 J-35 








 (4) the Canadian Issuer and the Canadian Guarantors have entered into any
supplemental Security Documents that are necessary to grant to each Secured Debt Representative, for the ratable benefit of the holders of any Secured Debt outstanding on or prior to the date of the incurrence of such Additional Secured Debt, a
security interest in any assets or property of Canadian Issuer and the Canadian Guarantors not otherwise granted under the Security Documents then in effect to the extent that such grantors grant a security interest in such assets to the holders of
such Additional Secured Debt or to any of their representatives (such supplemental Security Documents shall contain such additional customary covenants, representations, conditions (including delivery of customary legal opinions) and other
provisions relating to such additional assets or the granting of such security interest as the Canadian Collateral Trustee or any such Secured Debt Representative in respect of such existing Secured Debt may reasonably request (collectively,
“Supplemental Security Documents”)); and 
 (5) the Canadian Issuer has caused a copy of
the Additional Secured Debt Designation to be delivered to each then existing Secured Debt Representative. 
 Although the Canadian Issuer shall
be required to deliver a copy of each Additional Secured Debt Designation, Supplemental Security Document and each Collateral Trust Joinder to each then existing Secured Debt Representative, the failure to so deliver a copy of the Additional Secured
Debt Designation, Supplemental Security Document and/or Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the status of such debt as Additional Secured Debt if the other requirements of this Section 3.8
are complied with. Each of the Canadian Collateral Trustee and the other then existing Secured Debt Representative shall have the right to request that the Canadian Issuer shall provide a copy of any legal opinion of counsel (which may be provided
by internal counsel to the Canadian Issuer) proved to the holders of Additional Secured Debt or their Secured Debt representative) as to the Additional Secured Debt being secured by a valid and perfected security interest; provided,
however, that such legal opinion or opinions need not address any collateral of a type or located in a jurisdiction not previously covered by any legal opinion delivered by or on behalf of the Canadian Issuer. Notwithstanding the foregoing,
nothing in this Agreement will be construed to allow the Canadian Issuer or any other Canadian Guarantor to incur additional Indebtedness or grant additional Liens unless in each case otherwise permitted by the terms of all applicable Secured Debt
Documents. 
 (c) With respect to any Series of Priority Lien Debt or Series of Parity Lien Debt incurred after
the date of this Agreement, the Canadian Issuer and each Canadian Guarantor agrees to take such actions (if any) (including any acknowledgments by the Canadian Issuer or any of the other Canadian Guarantors of guarantees or security that are
applicable to Priority Lien Debt or Parity Lien Debt, as the case may be, or the execution of any Supplemental Security Documents) as may (subject to Section 5.12) from time to time reasonably be requested by the Canadian Collateral Trustee,
any Secured Debt Representative or any Act of Required Debtholders, and enter into any Supplemental Security Documents and such other agreements, amendments, modifications and/or supplements to the then existing guarantees and Security Documents (or
execute and deliver such additional guarantees and Security Documents) as may (subject to Section 5.12) from time to time be reasonably requested by the Canadian Collateral Trustee in order to cure any ambiguity, mistake, defect or
inconsistency that does not adversely affect the legal rights under this Agreement of any holder of Secured Obligations (or as contemplated by the following Section 3.8(d)), to ensure that the relevant additional Priority Lien Obligations or
Parity Lien Obligations, as the case may be, are secured by, and entitled to the

  

 J-36 








 
benefits of, the relevant guarantees and Security Documents, and each Secured Party (by its acceptance of the benefits hereof) hereby agrees to, and authorizes the Canadian Collateral Trustee to
enter into, any such Supplemental Security Documents, agreements, amendments, modifications and/or supplements (and additional guarantees and Security Documents). 
 (d) All parties hereto acknowledge and agree that, as of the date of this Agreement, the Security Documents as then in effect
may not secure any Priority Lien Obligations. At such time (if any) as any Priority Lien Debt becomes entitled to the benefits of this Agreement, additional Security Documents shall be required to be entered into to secure such Priority Lien Debt.
Any such Security Documents shall be required to apply only to the Collateral (after giving effect thereto) and shall be in form and substance substantially the same (although providing Priority Liens and other appropriate modifications) as the
respective Security Documents securing the Parity Lien Obligations (after giving effect to any Supplemental Security Documents executed for the benefit of the holders of such Parity Lien Obligations) and otherwise in form and substance reasonably
satisfactory to the Canadian Collateral Trustee and the Canadian Issuer and the Canadian Guarantors party thereto (subject to Section 5.12). 
 ARTICLE 4. OBLIGATIONS ENFORCEABLE BY THE CANADIAN ISSUER AND THE CANADIAN GUARANTORS 
 SECTION 4.1 Release of Liens on Collateral. 
 (a) The Canadian Collateral Trustee’s Liens
on the Collateral will be released (automatically and without the requirement of any further action by the Canadian Collateral Trustee or any other Person): 
 (1) in whole, upon (A) payment in full and discharge of all outstanding Secured Debt and all other Secured Obligations
that are outstanding (other than any indemnification or other contingent liabilities in respect of which no claim or demand for payment has been made at such time), due and payable at the time all of the Secured Debt is paid in full and discharged
and (B) termination or expiration of all commitments to extend credit under all Secured Debt Documents and the cancellation or termination or cash collateralization (at the lower of (1) 101% of the aggregate undrawn amount and (2) the
percentage of the aggregate undrawn amount required for release of Liens under the terms of the applicable Secured Debt Documents) of all outstanding letters of credit issued pursuant to any Secured Debt Documents; 
 (2) as to any Collateral that is sold, transferred or otherwise disposed of by the Canadian Issuer or any Canadian Guarantor
to a Person that is not (either before or after such sale, transfer or disposition) the Canadian Issuer or a Restricted Subsidiary (as defined under the Indenture) of the Canadian Issuer in a transaction or other circumstance that complies with
Section 4.10 of the Indenture and is permitted by all of the other Secured Debt Documents, at the time of such sale, transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of; provided that
the Canadian Collateral Trustee’s Liens upon the Collateral will not be released if the sale or disposition is subject to Section 5.01 of the Indenture; 
 (3) as to any Collateral of a Restricted Subsidiary (as defined under the Indenture) that is designated as an Unrestricted
Subsidiary (as defined under the Indenture) in

  

 J-37 








 
compliance with the provisions of the Indenture and any other relevant provisions of any other Secured Debt Documents, at the time such Restricted Subsidiary is designated as an Unrestricted
Subsidiary; and 
 (4) as to a release of all or substantially all of the Collateral, if (A) consent to the
release of that Collateral has been given by the requisite percentage or number of holders of each Series of Secured Debt at the time outstanding as provided for in the applicable Secured Debt Documents, and (B) the Canadian Issuer has
delivered an Officers’ Certificate to the Canadian Collateral Trustee certifying that all such necessary consents have been obtained. 
 (b) The Canadian Collateral Trustee agrees for the benefit of the Canadian Issuer and the other Canadian Guarantors that if the Canadian Collateral Trustee at any time receives: 
 (1) an Officers’ Certificate stating that (A) the signing officer has read Article 4 of this Agreement and
understands the provisions and the definitions relating hereto, (B) such officer has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not the conditions precedent in
this Agreement and all other Secured Debt Documents, if any, relating to the release of the Collateral have been complied with and (C) in the opinion of such officer, such conditions precedent, if any, have been complied with; and 

(2) the proposed instrument or instruments releasing such Lien as to such property in recordable form, if applicable;

 then the Canadian Collateral Trustee will execute (with such acknowledgements and/or notarizations as are required) and deliver such release
to the Canadian Issuer or other applicable Canadian Guarantor on or before the later of (x) the date specified in such request for such release and (y) the fifth Business Day after the date of receipt of the items required by this
Section 4.1(b) by the Canadian Collateral Trustee. 
 (c) The Canadian Collateral Trustee hereby agrees that
in the case of any release pursuant to clause (2) of Section 4.1(a), if the terms of any such sale, transfer or other disposition require the payment of the purchase price to be contemporaneous with the delivery of the applicable release,
then, at the written request of and at the expense of the Canadian Issuer or other applicable Canadian Guarantor, the Canadian Collateral Trustee will either (A) be present at and deliver the release at the closing of such transaction or
(B) deliver the release under customary escrow arrangements that permit such contemporaneous payment and delivery of the release. 
 (d) Any amendment or supplement to the provisions of the Security Documents that releases Collateral will be effective only in accordance with the requirements set forth in this Section 4.1.

 SECTION 4.2 Delivery of Copies to Secured Debt Representatives. The Canadian Issuer will deliver to each Secured Debt
Representative a copy of (a) all Security Documents and (b) each Officers’ Certificate delivered to the Canadian Collateral Trustee pursuant to Section 4.1(b), together with copies of all documents delivered to the Canadian
Collateral Trustee with such Security Documents and/or Officers’ Certificate, as applicable. 
  

 J-38 








 SECTION 4.3 Canadian Collateral Trustee not Required to Serve, File or Record. The
Canadian Collateral Trustee is not required to serve, file, register or record any instrument releasing or subordinating its Liens on any Collateral; provided, however, the Canadian Collateral Trustee shall authorize the Canadian Issuer or
the applicable Canadian Guarantor or any agent or designee thereof (and the same are hereby authorized) to serve, file, register or record any instrument releasing or subordinating its Liens on any Collateral to the extent such release or

 J-39 








 (b) No written direction given to the Canadian Collateral Trustee by an Act
of Required Debtholders that in the sole judgment of the Canadian Collateral Trustee imposes, purports to impose or might reasonably be expected to impose upon the Canadian Collateral Trustee any obligation or liability not set forth in or arising
under this Agreement and the other Security Documents will be binding upon the Canadian Collateral Trustee unless the Canadian Collateral Trustee elects, at its sole option, to accept such direction. 
 SECTION 5.5 Limitation of Liability. The Canadian Collateral Trustee will not be responsible or liable for any action taken or
omitted to be taken by it hereunder or under any other Security Document, except for its own gross negligence or willful misconduct, as determined by a court of competent jurisdiction.

writing delivered to it by the Canadian Issuer or any other Canadian Guarantor in compliance with the provisions of this Agreement or delivered to it by any Secured Debt Representative as to the holders of Secured Obligations for whom it acts,
without being required to determine the authenticity thereof or the correctness of any fact stated therein or the propriety or validity of service thereof. The Canadian Collateral Trustee may act in reliance upon any instrument comporting with the

Canadian Collateral Trustee will not be required to advance or expend any funds or otherwise incur any financial liability in the performance of its duties or the exercise of its powers or rights hereunder unless, and only to the extent that, it has

 SECTION 5.11 Rights of the Canadian Collateral Trustee. In the event of any conflict between any terms and provisions set forth in
this Agreement and those set forth in any other Security Document, the terms and provisions of this Agreement shall supersede and control the terms and provisions of such other Security Document. In the event there is any bona fide, good faith
disagreement between the other parties to this Agreement or any of the other Security Documents resulting in adverse claims being made in connection with Collateral held by the Canadian Collateral Trustee and the terms of this Agreement or any of
the other Security Documents do not unambiguously mandate the action the Canadian Collateral Trustee is to take or not to take in connection therewith under the circumstances then existing, or the Canadian Collateral Trustee is in doubt as to what
action it is required to take or not to take hereunder or under the other Security Documents, it will be entitled to refrain from taking any action (and will incur no liability for doing so) until directed otherwise, subject to Section 5.10, in
writing by a request signed jointly by the parties hereto entitled to give such direction or by order of a court of competent jurisdiction. 
 SECTION 5.12 Limitations on Duty of Canadian Collateral Trustee in Respect of Collateral.

possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Canadian Collateral Trustee will not be responsible for filing any financing or
continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the Collateral. The Canadian Collateral Trustee will be deemed to have
exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property, and the Canadian Collateral Trustee will not be liable or responsible
for any loss or diminution in the value of any of the Collateral by reason of the operation of real estate markets or securities markets, or by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected and
maintained by the Canadian Collateral Trustee in good faith. 
 (b) The Canadian Collateral Trustee will not be
responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or
omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Canadian Collateral Trustee, for the validity or sufficiency of the Collateral or any agreement
or assignment contained therein, for the validity of the title of the Canadian Issuer or any Canadian Guarantor to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or
otherwise as to the maintenance of the Collateral. The Canadian Collateral Trustee hereby disclaims any representation or warranty to the present and future holders of the Secured Obligations concerning the perfection of the Liens granted hereunder
or in the value of any of the Collateral. 
  

 J-41 








 SECTION 5.13 Assumption of Rights, Not Assumption of Duties. Notwithstanding anything
to the contrary contained herein: 
 (1) each of the parties thereto will remain liable under each of the
Security Documents (other than this Agreement) to the extent set forth therein to perform all of their respective duties and obligations thereunder to the same extent as if this Agreement had not be executed; 
 (2) the exercise by the Canadian Collateral Trustee of any of its rights, remedies or powers hereunder will not release such
parties from any of their respective duties or obligations under the other Security Documents; and 
 (3) the
Canadian Collateral Trustee will not be obligated to perform any of the obligations or duties of any of the parties thereunder other than the Canadian Collateral Trustee. 
 SECTION 5.14 Hazardous Materials; No Liability for Clean Up; Indemnification. 
 In the event that the Canadian Collateral Trustee is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit
of another, which in the Canadian Collateral Trustee’s sole discretion, upon the advice of counsel, may cause the Canadian Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the
Canadian Collateral Trustee to incur, or be exposed to, any environmental liability or any liability under any other federal, provincial, territorial, local or foreign law, the Canadian Collateral Trustee reserves the right, instead of taking such
action, either to resign as Canadian Collateral Trustee or to arrange for the transfer of the title or control of the asset to a court appointed receiver. The Canadian Collateral Trustee will not be liable to any Person for any environmental
liability or any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of the Canadian Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or
relating to any kind of discharge or release or threatened discharge or release of any hazardous materials into the environment. 
 The Canadian Issuer and the Canadian Guarantors shall jointly and severally defend, indemnify, and hold harmless the Canadian Collateral Trustee and its officers, directors, employees and agents and their respective representatives, heirs,
successors and assigns from and against any claims, demands, penalties, fines, liabilities, settlements, damages, costs, or expenses of whatever kind or nature, known or unknown, contingent or otherwise, arising out of, or in any way related to,
(w) the presence, disposal, release, or threatened release of any Hazardous Materials which are on, from, or affecting the soil, water, vegetation, buildings, personal property, persons, animals, or otherwise; (x) any personal injury
(including wrongful death) or property damage (real or personal) arising out of or related to such Hazardous Materials; (y) any lawsuit brought or threatened, settlement reached, or government order relating to such Hazardous Materials, and/or
(z) any violation of laws, orders, regulations, requirements or demands of government authorities, or any policies or requirements of the Canadian Collateral Trustee, which are based upon or in any way related to such Hazardous Materials
including, without limitation, attorney and consultant fees and

  

 J-42 








 
expenses, investigation and laboratory fees, court costs, and litigation expenses; provided the Canadian Collateral Trustee shall not be entitled to indemnification hereunder with respect
to the foregoing clauses (w) through (z) to the extent such liability is found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Canadian
Collateral Trustee. For purposes of this paragraph, “Hazardous Materials” includes, without limit, any flammable explosives, radioactive materials, hazardous materials, hazardous wastes, hazardous or toxic substances, or related materials
defined in the Canadian Environmental Protection Act, 1999, Fisheries Act, Transportation of Dangerous Goods Act, 1992, the Migratory Birds Protection Act, 1994, the Species At Risk Act, the Hazardous Products Act, the Canada Shipping Act and the
Canada Wildlife Act, Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (42 U.S.C. Sections 9601, et. seq.), the Hazardous Materials Transportation Act, as amended (49 U.S.C. Sections 5108, et seq.), the
Resource Conservation and Recovery Act, as amended (42 U.S.C. Sections 6901, et seq.), and in the regulations adopted and publications promulgated pursuant thereto, or any other federal, provincial, territorial, state or local environmental law,
ordinance, rule, or regulation. The provisions of this paragraph shall be in addition to any and all other obligations and liabilities the Canadian Issuer and the Canadian Guarantors may have to any Indemnitee at common law, and shall survive the
termination of this Agreement.

 SECTION 6.2 Appointment of Successor Canadian Collateral Trustee. Upon any such resignation or removal, a successor Canadian Collateral Trustee may be appointed by an Act of Required Debtholders,
subject to the prior written consent of the Canadian Issuer (such consent not to be unreasonably withheld or delayed). If no successor Canadian Collateral Trustee has been so appointed and accepted such appointment within 30 days after the
predecessor Canadian Collateral Trustee gave notice of resignation or was removed, the retiring Canadian Collateral Trustee may (at the expense of the Canadian Issuer), at its option, appoint a successor Canadian Collateral Trustee, or petition a

necessary or desirable or reasonably requested by the successor Canadian Collateral Trustee to transfer to the successor Canadian Collateral Trustee all Liens, interests, rights, powers and remedies of the predecessor Canadian Collateral Trustee in
respect of the Security Documents or the Trust Estates.

consolidation to which the Canadian Collateral Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust business of the Canadian Collateral Trustee shall be the successor of the Canadian Collateral Trustee
pursuant to Section 6.3, provided that (i) without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto, except where an instrument of transfer or assignment is
required by law to effect such succession, anything herein to the contrary notwithstanding, such Person satisfies the eligibility requirements specified in clauses (1) through (4) of Section 6.2 and (ii) prior to any such merger,
conversion or consolidation, the Canadian Collateral Trustee shall have notified the Canadian Issuer, each Priority Lien Representative and each Parity Lien Representative thereof in writing.

 J-44 








 
the terms of the Secured Debt Documents to be secured by the Collateral or preserving, perfecting or establishing the priority of the Liens thereon or the rights of the Canadian Collateral
Trustee therein, (ii) curing any ambiguity, defect or inconsistency; or (iii) providing for the assumption of the Canadian Issuer’s or any Canadian Guarantors’ Obligations under any Security Document in the case of a merger or

right of any holder of Secured Obligations:

Debtholders” or “Required Parity Lien Debtholders”), 
 (B) to share in the order of application
described in Section 3.4 in the proceeds of enforcement of or realization on any Collateral, or

 (b) Notwithstanding Section 7.1(a) but subject to
Sections 7.1(a)(2) and 7.1(a)(3): 
 (1) any mortgage or other Security Document that secures Parity Lien
Obligations (but not Priority Lien Obligations) may be amended or supplemented with the approval of the Canadian Collateral Trustee acting as directed in writing by the Required Parity Lien Debtholders (or such other number or percentage of holders
of Parity Lien Debt as may be required under the applicable Parity Lien Documents), unless such amendment or supplement would not be permitted under the terms of this Agreement or the other Priority Lien Documents; 
 (2) any mortgage or other Security Document that secures Priority Lien Obligations (but not Parity Lien Obligations) may be
amended or supplemented with the approval of the Canadian Collateral Trustee acting as directed in writing by the Required Priority Lien Debtholders (or such other number or percentage of holders of Priority Lien Debt as may be required under the
applicable Priority Lien Documents), unless such amendment or supplement would not be permitted under the terms of this Agreement or the other Parity Lien Documents; and 
  


 J-45 








 (3) any mortgage or other Security Document that secures Priority Lien
Obligations (but not Parity Lien Obligations) may be amended or supplemented with the approval of the Canadian Collateral Trustee acting as directed in writing by the Required Priority Lien Debtholders (or such other number or percentage of holders
of Priority Lien Debt as may be required under the applicable Priority Lien Documents), unless such amendment or supplement would not be permitted under the terms of this Agreement or the other Parity Lien Documents. 
 (c) The Canadian Collateral Trustee will not enter into any amendment or supplement unless it has received an Officers’
Certificate to the effect that such amendment or supplement will not result in a breach of any provision or covenant contained in any of the Secured Debt Documents. Prior to executing any amendment or supplement pursuant to this Section 7.1,
the Canadian Collateral Trustee will be entitled to receive an opinion of counsel of the Canadian Issuer (which may be provided by internal counsel to the Canadian Issuer) to the effect that the execution of such document is authorized or permitted
hereunder, and with respect to amendments adding Collateral, an opinion of counsel of the Canadian Issuer (which may be provided by internal counsel to the Canadian Issuer) addressing customary perfection, and if such additional Collateral consists
of equity interests of any Person, priority matters with respect to such additional Collateral.

holders of Secured Debt and the Secured Debt Representatives agree that each Security Document that secures Secured Obligations will include the following language: 
 “Notwithstanding anything herein to the contrary, the lien and security interest granted to the Canadian Collateral Trustee pursuant to this Agreement and the exercise of any right or remedy by such
Canadian Collateral Trustee hereunder are subject to the provisions of the Canadian Collateral Trust Agreement, dated as of December 22, 2009 among Canadian Issuer, the Canadian Guarantors from time to time party thereto, the Priority Lien
Representatives from time to time party thereto, the Parity Lien Representatives from time to time party thereto, The Bank of New York Mellon, as Trustee under the Indenture (as defined therein) and Computershare Trust Company of Canada, as Canadian

Agreement and this Agreement, the terms of the Collateral Trust Agreement will govern.” 
 ; provided, however, that if the
jurisdiction in which any such Secured Debt Document will be filed prohibits the inclusion of the language above or would prevent a document containing such language from being recorded, the applicable Secured Debt Representatives agree, prior to
such Secured Debt Document being entered into, to negotiate in good faith replacement language stating that the lien and security interest granted under such Secured Debt Document is subject to the provisions of this Agreement. 
  

 J-46

vote of holders of Secured Debt, each Series of Secured Debt will cast its votes in accordance with the Secured Debt Documents governing such Series of Secured Debt. The amount of Secured Debt to be voted by a Series of Secured Debt will equal
(1) the aggregate principal amount of Secured Debt held by such Series of Secured Debt (including outstanding letters of credit whether or not then available or drawn), plus (2) other than in connection with an exercise of remedies,
the aggregate unfunded commitments to extend credit which, when funded, would constitute Indebtedness of such Series of Secured Debt. Following and in accordance with the outcome of the applicable vote under its Secured Debt Documents, the Secured
Debt Representative of each Series of Secured Debt will vote the total amount of Secured Debt under that Series of Secured Debt as a block in respect of any vote under this Agreement.

perfected Liens upon the Collateral, in each case, as contemplated by, and with the Lien priority required under, the Secured Debt Documents, and subject to the limitations set forth in the Secured Debt Documents. 
 (b) Upon the reasonable request of the Canadian Collateral Trustee or any Secured Debt Representative at any time and from
time to time, the Canadian Issuer and each of the Canadian Guarantors will promptly execute, acknowledge and deliver such Security Documents, instruments, certificates, notices and other documents, and take such other actions as shall be reasonably
required, or that the Canadian Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Secured Debt Documents for the benefit of
the holders of Secured Obligations (it being expressly agreed that the Canadian Collateral Trustee has no responsibility to monitor, protect or perfect any such Liens or benefits). 
 (c) The Canadian Issuer shall verify to the Canadian Collateral Trustee in its annual certificate of compliance to the
Canadian Collateral Trustee, among other things, that insurance in quality and quantity sufficient and in conformity with the requirements under the Indenture and pursuant to the terms of the Canadian Collateral Trust Agreement has been obtained and
is in place. The Canadian Collateral Trustee shall not itself have any responsibility to obtain insurance to protect the interest of any party to the secured property and it further shall have no responsibility whatsoever for or duty to determine if
any insurance policy put into place against the Collateral to protect the interest of the Trustee and the holders of Canadian Notes is in quality or quantity sufficient and in conformity with the value required by the terms of this Agreement or the
Indenture, but shall ascertain that the Canadian Collateral Trustee is designated as a loss payee on any such insurance policies delivered to it.

hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of the Canadian Issuer and the other Canadian Guarantors hereunder will inure to the sole and exclusive benefit of, and be
enforceable by, the Canadian Collateral Trustee, each Secured Debt Representative and each present and future holder of Secured Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of

 SECTION 7.6 Delay and Waiver. No failure to exercise, no course of dealing
with respect to the exercise of, and no delay in exercising, any right, power or remedy arising under this Agreement or any of the other Security Documents will impair any such right, power or remedy or operate as a waiver thereof. No single or
partial exercise of any such right, power or remedy will preclude any other or future exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law.

up and whether or not the trusts of this Agreement shall be in course of administration by or under the direction of the court. This section 7.10 shall survive the resignation or replacement of the Canadian Collateral Trustee or the termination of
this Agreement. 
 SECTION 7.11 Indemnity. 
 (a) The Canadian Issuer and the Canadian Guarantors jointly and severally agree to defend, indemnify, pay and hold harmless
the Canadian Collateral Trustee, each Secured Debt Representative and each of their respective Affiliates and each and all of the directors, officers, partners, trustees, employees, attorneys and agents, and (in each case) their respective heirs,
representatives, successors and assigns (each of the foregoing, an “Indemnitee”) from and against any and all Indemnified Liabilities; provided, no Indemnitee will be entitled to indemnification hereunder
with respect to any Indemnified Liability to the extent such Indemnified Liability is found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such
Indemnitee. 
 (b) All amounts due under this Section 7.11 will be payable promptly following demand.

 (c) To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in
Section 7.11(a) may be unenforceable in whole or in part because they violate any law or public policy, each of the Canadian Issuer and the Canadian Guarantors will contribute the maximum portion that it is permitted to pay and satisfy under
applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by Indemnitees or any of them. 
 (d) No Canadian Issuer or Canadian Guarantor will assert any claim against any Indemnitee, on any theory of liability, for any lost profits or special, indirect or consequential damages or (to the fullest extent a claim for punitive damages
may lawfully be waived) any punitive damages arising out of, in connection with, or as a result of, this Agreement or any other Secured Debt Document or any agreement or instrument or transaction contemplated hereby or relating in any respect to any
Indemnified Liability, and each of the Canadian Issuer and the Canadian Guarantors hereby forever waives, releases and agrees not to sue upon any claim for any

  

 J-51 








 
such lost profits or special, indirect, consequential or (to the fullest extent lawful) punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor.

 (e) The agreements in this Section 7.11 will survive repayment of all other Secured Obligations and the
removal or resignation of the Canadian Collateral Trustee. 
 SECTION 7.12 Severability. If any provision of this
Agreement is invalid, illegal or unenforceable in any respect or in any jurisdiction, the validity, legality and enforceability of such provision in all other respects and of all remaining provisions, and of such provision in all other
jurisdictions, will not in any way be affected or impaired thereby. 
 SECTION 7.13 Headings. Section headings herein
have been inserted for convenience of reference only, are not to be considered a part of this Agreement and will in no way modify or restrict any of the terms or provisions hereof. 
 SECTION 7.14 Obligations Secured. All obligations of the Canadian Issuer and the Canadian Guarantors set forth in or arising under
this Agreement will be Secured Obligations and are secured by all Liens granted by the Security Documents. 
 SECTION 7.15
Governing Law. THE LAWS OF THE PROVINCE OF ONTARIO WILL GOVERN AND BE USED TO CONSTRUE THIS AGREEMENT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION
WOULD BE REQUIRED THEREBY. 
 SECTION 7.16 Consent to Jurisdiction. All judicial proceedings brought against any party
hereto arising out of or relating to this Agreement or any of the other Security Documents may be brought in any state or federal court of competent jurisdiction in the State, County and City of New York or any court of the Province of Ontario. By
executing and delivering this Agreement, each party hereto, for itself and in connection with its properties, irrevocably: 
 (1) accepts generally and unconditionally the nonexclusive jurisdiction and venue of such courts; 
 (2) waives any defense of forum non conveniens; 
 (3) agrees that
service of all process in any such proceeding in any such court may be made by registered or certified mail, return receipt requested, to such party at its address provided in accordance with Section 7.7; 
 (4) agrees that service as provided in clause (3) above is sufficient to confer personal jurisdiction over such party in
any such proceeding in any such court and otherwise constitutes effective and binding service in every respect; and 
  

 J-52 








 (5) agrees each party hereto retains the right to serve process in any other
manner permitted by law or to bring proceedings against any party in the courts of any other jurisdiction. 
 SECTION 7.17
Waiver of Jury Trial. Each party to this Agreement waives its rights to a jury trial of any claim or cause of action based upon or arising under this Agreement or any of the other Security Documents or any dealings between them relating to
the subject matter of this Agreement or the intents and purposes of the other Security Documents. The scope of this waiver is intended to be all-encompassing of any and all disputes that may be filed in any court and that relate to the subject
matter of this Agreement and the other Security Documents, including contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each party to this Agreement acknowledges that this waiver is a material
inducement to enter into a business relationship, that each party hereto has already relied on this waiver in entering into this Agreement, and that each party hereto will continue to rely on this waiver in its related future dealings. Each party
hereto further warrants and represents that it has reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its jury trial rights following consultation with legal counsel. This waiver is irrevocable, meaning that it
may not be modified either orally or in writing (other than by a mutual written waiver specifically referring to this Section 7.17 and executed by each of the parties hereto), and this waiver will apply to any subsequent amendments, renewals,
supplements or modifications of or to this Agreement or any of the other Security Documents or to any other documents or agreements relating thereto. In the event of litigation, this Agreement may be filed as a written consent to a trial by the
court. 
 SECTION 7.18 Counterparts. This Agreement may be executed in any number of counterparts (including by
facsimile), each of which when so executed and delivered will be deemed an original, but all such counterparts together will constitute but one and the same instrument. 
 SECTION 7.19 Effectiveness. This Agreement will become effective upon the execution of a counterpart hereof by each of the parties hereto and receipt by each party of written notification of such
execution and written or telephonic authorization of delivery thereof. 
 SECTION 7.20 Additional Canadian Guarantors.
The Canadian Issuer will cause each Person that becomes a successor to the Canadian Issuer or becomes a Canadian Guarantor or is required by any Secured Debt Document to become a party to this Agreement to become a party to this Agreement, for all
purposes of this Agreement, by causing such Person to execute and deliver to the Canadian Collateral Trustee a Collateral Trust Joinder, whereupon such Person will be bound by the terms hereof to the same extent as if it had executed and delivered
this Agreement as of the date hereof. The Canadian Issuer shall promptly provide each Secured Debt Representative with a copy of each Collateral Trust Joinder executed and delivered pursuant to this Section 7.20; provided, however, that
the failure to so deliver a copy of the Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the inclusion of such Person as a Canadian Guarantor if the other requirements of this Section 7.20 are complied
with. 
 SECTION 7.21 Continuing Nature of this Agreement; Discharge of Priority Lien Obligations; Discharge of Parity Lien
Obligations. 
 (a) This Agreement, including the subordination provisions hereof, will be reinstated if at
any time any payment or distribution in respect of any of the Priority Lien Obligations is rescinded or must otherwise be returned in an Insolvency or Liquidation Proceeding

  

 J-53 








 
or otherwise by any holder of Priority Lien Obligations or Priority Lien Representative or any representative of any such party (whether by demand, settlement, litigation or otherwise). In the
event that all or any part of a payment or distribution made with respect to the Priority Lien Obligations is recovered from any holder of Priority Lien Obligations or any Priority Lien Representative in an Insolvency or Liquidation Proceeding or
otherwise, such payment or distribution received by any holder of Parity Lien Obligations or Parity Lien Representative with respect to the Parity Lien Obligations, as the case may be, from the proceeds of any Collateral or any title insurance
policy required by any real property mortgage at any time after the date of the payment or distribution that is so recovered, whether pursuant to a right of subrogation or otherwise, that Parity Lien Representative or that holder of a Parity Lien
Obligation, as the case may be, will forthwith deliver the same to the Canadian Collateral Trustee, for the account of the holders of the Priority Lien Obligations to be applied in accordance with Section 3.4. Until so delivered, such proceeds
will be held by that Parity Lien Representative or that holder of a Parity Lien Obligation, as the case may be, for the benefit of the holders of the Priority Lien Obligations. For the avoidance of doubt, if a Discharge of Priority Lien Obligations
occurs prior to the termination of this Agreement, to the extent that additional Priority Lien Obligations are incurred in accordance with Section 3.8, effective upon the incurrence of such additional Priority Lien Obligations in accordance
with Section 3.8, there shall no longer be a Discharge of Priority Lien Obligations for purposes of this Agreement. 
 SECTION 7.22 Insolvency. This Agreement will be applicable both before and after the commencement of any Insolvency or Liquidation Proceeding by or against the Canadian Issuer or any Canadian Guarantor. The relative rights, as
provided for in this Agreement, will continue after the commencement of any such Insolvency or Liquidation Proceeding on the same basis as prior to the date of the commencement of any such case, as provided in this Agreement. 
 SECTION 7.23 Rights and Immunities of Secured Debt Representatives. The Trustee will be entitled to all of the rights, protections,
immunities and indemnities set forth in the Indenture and any future Secured Debt Representative will be entitled to all of the rights, protections, immunities and indemnities set forth in the credit agreement, indenture or other agreement governing
the applicable Secured Debt with respect to which such Person will act as representative, in each case as if specifically set forth herein. In no event will any Secured Debt Representative be liable for any act or omission on the part of the
Canadian Issuer, the Canadian Guarantors or the Canadian Collateral Trustee hereunder. 
 SECTION 7.24 Force Majeure. In
no event shall the Canadian Collateral Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without
limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and
hardware) services; it being understood that the Canadian Collateral Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

 SECTION 7.25 U.S.A. Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A.
Patriot Act and other similar laws in Canada, the Canadian Collateral Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that
identifies each person or legal entity that establishes a relationship or opens an account with the Canadian Collateral Trustee. The

  

 J-54 








 
parties to this Agreement agree that they will provide the Canadian Collateral Trustee with such information as it may request in order for the Canadian Collateral Trustee to satisfy the
requirements of the U.S.A. Patriot Act and other similar laws in Canada. 
 The Canadian Collateral Trustee shall retain the
right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Canadian Collateral Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance
with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Canadian Collateral Trustee, in its sole judgment, determine at any time that its acting under this Agreement has resulted in its
being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 Business Days’ written notice to the other parties to this Agreement,
provided (i) that the Canadian Collateral Trustee’s written notice shall describe the circumstances of such non-compliance; (ii) that if such circumstances are rectified to the Canadian Collateral Trustee’s satisfaction within
such 10 Business Day period, then such resignation shall not be effective. 
 SECTION 7.26 Privacy Act. 
 The parties acknowledge that federal and/or provincial legislation that addresses the protection of individuals’ personal information
(collectively, the “Privacy Laws”) applies to obligations and activities under this Agreement. Despite any other provision of this Agreement, no party shall take or direct any action that would contravene, or cause the other to contravene,
applicable Privacy Laws. The Canadian Issuer shall, prior to transferring or causing to be transferred personal information to the Canadian Collateral Trustee, obtain and retain required consents of the relevant individuals to the collection, use
and disclosure of their personal information, or shall have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Canadian Collateral Trustee shall use
commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws. Specifically, the Canadian Collateral Trustee agrees: (a) to have a designated chief privacy officer; (b) to maintain policies and procedures
to protect personal information and to receive and respond to any privacy complaint or inquiry; (c) to use personal information solely for the purposes of providing its services under or ancillary to this Agreement and not to use it for any
other purpose except with the consent of or direction from the Issuer or the individual involved; (d) not to sell or otherwise improperly disclose personal information to any third party; and (e) to employ administrative, physical and
technological safeguards to reasonably secure and protect personal information against loss, theft, or unauthorized access, use or modification. 
 SECTION 7.27 Judgment Currency 
 (1) If for the purpose of obtaining or enforcing judgement
against the Canadian Issuer or a Canadian Guarantor in any court in any jurisdiction, it becomes necessary to convert into any other currency (such other currency being hereinafter in this Section 7.27 referred to as the “Judgment
Currency”) an amount due in the lawful currency of Canada (“Canadian Dollars”) or Dollars under this Agreement, the conversion will be made at the rate of exchange prevailing on the Business Day immediately preceding 
  

 J-55 








 (a) the date of actual payment of the amount due, in the case of any proceeding in the courts of the
Province of Ontario or in the courts of any other jurisdiction that will give effect to such conversion being made on such date, or 
 (b) the
date on which the judgement is given, in the case of any proceeding in the courts of any other jurisdiction (the date as of which such conversion is made pursuant to this Section 7.27(1)(b) being hereinafter in this Section 7.27 referred
to as the “Judgment Conversion Date”). 
 (2) If, in the case of any proceeding in the court of any jurisdiction referred to in
Section 7.27 (1)(b), there is a change in the rate of exchange prevailing between the Judgment Conversion Date and the date of actual payment of the amount due, the Borrower will pay such additional amount (and, if applicable, such lesser
amount) as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of Canadian Dollars or Dollars, as the case may be, which could
have been purchased with the amount of Judgment Currency stipulated in the judgement or judicial order at the rate of exchange prevailing on the Judgment Conversion Date. 
 (3) Any amount due from the Canadian Issuer or a Canadian Guarantor, as applicable, under the provisions of Section 7.27 (2) will be due as a separate debt and will not be affected by judgement
being obtained for any other amounts due under or in respect of this Agreement. 
 (4) The term “rate of exchange” in this
Section 7.27 means: 
 (a) for a conversion of Canadian Dollars to the Judgment Currency, the reciprocal of the official noon rate of
exchange published by the Bank of Canada for the date in question for the conversion of the Judgment Currency to Canadian Dollars; 
 (b) for a
conversion of Dollars to the Judgment Currency when the Judgment Currency is Canadian Dollars, the official noon rate of exchange published by the Bank of Canada for the date in question for the conversion of Dollars to Canadian Dollars.

funds, at par plus accrued interest plus any fees and out-of-pocket expenses that at such time are accrued and unpaid but would be, under the terms of the relevant Priority Lien Documents, reimbursable by the U.S. Issuer, without warranty or
representation or recourse, on a pro rata basis for cash consideration in immediately available funds or with respect to any Priority Lien Obligations that are Hedging Obligations at a price equal to the net aggregate amount then owing to
counterparties under such Hedge Agreements, including all amounts owing to the counterparties as a result of the termination (or early termination) thereof (collectively, the “Purchase Price”). For the avoidance of doubt, the
Purchase Price will exclude any commitment or other fees that would have become due and payable in respect of unfunded commitments under the relevant Priority Lien Documents. Within 5 Business Days after receipt of the Purchase Notice, each Priority
Lien Representative will deliver to the Collateral Trustee and the U.S. Issuer a statement of the amount of Priority Lien Debt and other Priority Lien Obligations then outstanding for which it is the Priority Lien Representative, which statement
will also include wire transfer information and the portion of the Purchase Price to be remitted to each holder of Priority Lien Obligations then outstanding for which it is the Priority Lien Representative (the “Calculation
Notice”). 
 (b) Within 5 Business Days after receipt of the Calculation Notice, the Collateral Trustee will send a
copy of the Calculation Notice to the U.S. Issuer and each Parity Lien Representative and will include a statement as to the aggregate principal amount of Priority Lien Obligations that each holder of Parity Lien Obligations is entitled to purchase
pursuant to this Section 2.12. Within 10 Business Days after receipt of the Calculation Notice and the information referenced in the immediately preceding sentence by such holders of Parity Lien Obligations, each holder of Parity Lien
Obligations (together with its respective Affiliates and designees, collectively, the “Purchasers”) shall deliver written notice to the Collateral Trustee of its intent to exercise its purchase option hereunder,
and such written notice shall constitute an irrevocable commitment from such Purchaser to purchase its pro rata share of the Priority Lien Obligations at the Purchase Price. Any holder of Parity Lien Obligations who fails to deliver such notice
(each, a “Declining Holder”) shall be deemed to have elected not to exercise its purchase option hereunder, and the Collateral Trustee shall promptly following such 10 Business Day period allocate, in a written notice to the
remaining Purchasers, each Declining Holder’s pro rata share of the Priority Lien Obligations ratably among the remaining Purchasers (the “Accepting Holders”). Upon receipt of notice from the Collateral Trustee of an
allocation of additional Priority Lien Obligations, each Accepting Holder shall deliver written notice to the Collateral Trustee of its intent to exercise its purchase option hereunder with respect to such additional Priority Lien Obligations. Any
holder of Parity Lien Obligations who fails to deliver such notice within 10 Business Days after receipt shall be deemed not to exercise its purchase option hereunder with respect to such additional Priority Lien Obligations. Following such 10
Business Day period, to the extent that any Priority Lien Obligations have not been elected for purchase, the Collateral Trustee shall offer each Accepting Holder the option to purchase any such remaining Priority Lien Obligations on a pro rata
basis. If not all remaining Priority Lien Obligations are elected for purchase by the Accepting Holders on a pro rata basis, the Collateral Trustee may then offer the Accepting Holders the opportunity to purchase more than a pro rata allocation of
Priority Lien Obligations, so long as no other holder of Parity Lien Obligations shall have object to such non-pro rata allocation. 
  

 K-37 








 (c) On the date specified by the Collateral Trustee on behalf of the Purchasers (such date,
the “Purchase Date”), the holders of the Priority Lien Obligations shall sell to the Purchasers all (but not less than all) of the Priority Lien Obligations that are outstanding on the Purchase Date at the Purchase Price,
subject to (i) any required approval of any court or other regulatory or governmental authority then in effect and (ii) compliance with all other applicable laws. Upon the sale of the Priority Lien Obligations to the Purchasers, all
commitments to fund any purchased Priority Lien Obligations will automatically terminate, and U.S. Issuer hereby consents to such termination. 
 (d) The Purchase Price shall be remitted by wire transfer in federal funds to such bank accounts of the Priority Lien Representatives set forth in the Calculation Notice. Interest shall be calculated to
but excluding the Business Day on which such sale occurs if the amounts so paid by the Collateral Trustee and holders of the Parity Lien Obligations to the bank accounts designated by the Priority Lien Representatives are received in such bank
accounts prior to 12:00 p.m., New York City time, and interest shall be calculated to and including such Business Day if the amounts so paid by the Collateral Trustee and holders of the Parity Lien Obligations to the bank accounts designated by the
Priority Lien Representatives are received in such bank accounts later than 12:00 p.m., New York City time. 
 (e) The sale of
the Priority Lien Obligations shall be expressly made without warranty or representation of any kind by the Priority Lien Representatives and the holders of Priority Lien Obligations as to the Priority Lien Obligations, the Collateral or otherwise
and without recourse to the Priority Lien Representatives and the holders of Priority Lien Obligations, except that each of the Priority Lien Representatives and the holders of Priority Lien Obligations shall represent and warrant severally as to
the Priority Lien Obligations then owing to it: (i) the amount of the Priority Lien Obligations being purchased as reflected in the books and records of the Priority Lien Representatives or such holders of Priority Lien Obligations (but without
representation or warranty as to the collectability, validity or enforceability thereof); (ii) that the Priority Lien Representatives and such holders of the Priority Lien Obligations own the Priority Lien Obligations and are transferring the
Priority Lien Obligations free and clear of any liens or encumbrances; and (iii) the Priority Lien Representatives and such holders of the Priority Lien Obligations have the right to sell the Priority Lien Obligations and the sale is duly
authorized. 
 (f) On the Purchase Date, each Purchaser shall execute an assignment agreement in form and substance reasonably
satisfactory to each Priority Lien Representative and each Parity Lien Representative in order to effect the sale of the Priority Lien Obligations to such Purchaser (and U.S. Issuer hereby consents to such assignment and sale). After such sale
becomes effective, the Priority Lien Obligations will remain outstanding and enforceable and will remain secured by the Priority Liens upon the Collateral in accordance with the applicable provisions of the Priority Lien Documents as in effect at
the time of such sale, and the Purchasers thereof will be entitled to the benefit of the Priority Liens upon the Collateral and sharing rights in the proceeds thereof in accordance with the provisions of the Priority Lien Documents and this
Agreement as in effect at the time of such sale, as fully as if the sale of the Priority Lien Debt had not been made. 
 (g)
Notwithstanding the foregoing, following the purchase of the entire aggregate amount of the Priority Lien Obligations by the holders of Parity Lien Obligations (or their Affiliates or designees), such holders of Parity Lien Obligations will have no
further obligation to fund any commitments in respect of any Priority Lien Obligations so purchased and all outstanding commitments in respect of any Priority Lien Obligations will automatically terminate. 
  

 K-38 








 (h) In no event will any holder of Junior Lien Obligations, any Junior Lien Representative,
the U.S. Issuer or any U.S. Guarantor or any of their respective Affiliates have the option to purchase any Priority Lien Obligations pursuant to this Section 2.12. Notwithstanding the foregoing, upon receipt of a Purchase Notice, the U.S.
Issuer may, within 5 Business Days, notify the Collateral Trustee, the Priority Lien Representative and each Parity Lien Representative that it will, within 30 days of the date of the Purchase Notice, repay all amounts outstanding under any Priority
Lien Obligations and terminate all commitments in respect thereof. For the duration of such 30 day period, no holder of any Parity Lien Obligations will take any action in respect of this Section 2.12; provided, that if the U.S. Issuer
does not repay all amounts outstanding under any Priority Lien Obligations and terminate all commitments in respect thereof within such 30 day period, the holders of Parity Lien Obligations may, following such 30 day period, take any and all actions
described in this Section 2.12. 
 (i) Neither the Collateral Trustee, any Priority Lien Representative nor any holder of
Priority Lien Obligations will take any action with respect to the Collateral nor exercise any right or remedy available under the Priority Lien Documents (including any action to accelerate the Priority Lien Debt) during the period following the
receipt of a Purchase Notice until the end of the Purchase Option Period, including, without limitation during the 30 day period set forth in Section 2.12(h).

 SECTION 3.8 Additional Secured Debt. 
 (a) The Collateral Trustee will, as trustee hereunder, perform its undertakings set forth in Section 3.1(a) with respect to each holder
of Secured Obligations of a Series of Secured Debt that is issued or incurred after the date hereof that: 
 (1)
holds Secured Obligations that are identified as Junior Lien Debt, Parity Lien Debt or Priority Lien Debt in accordance with the procedures set forth in Section 3.8(b); and 
 (2) signs, through its designated Secured Debt Representative identified pursuant to Section 3.8(b), a Collateral Trust
Joinder and delivers the same to the Collateral Trustee. 
 (b) The U.S. Issuer will be permitted to designate as an additional
holder of Secured Obligations hereunder each Person who is, or who becomes, the registered holder of Junior Lien Debt, the registered holder of Parity Lien Debt or the registered holder of Priority Lien Debt incurred by the U.S. Issuer or any other
U.S. Guarantor after the date of this Agreement in

  

 K-43 








 
accordance with the terms of all applicable Secured Debt Documents. The U.S. Issuer may only effect such designation by delivering to the Collateral Trustee an Additional Secured Debt Designation
stating that: 
 (1) the U.S. Issuer or such other U.S. Guarantor intends to incur additional Secured Debt
(“Additional Secured Debt”) which will either be (i) Priority Lien Debt permitted by each applicable Secured Debt Document to be secured by a Priority Lien equally and ratably with all previously existing
and future Priority Lien Debt, (ii) Parity Lien Debt permitted by each applicable Secured Debt Document to be secured with a Parity Lien equally and ratably with all previously existing and future Parity Lien Debt or (iii) Junior Lien Debt
permitted by each applicable Secured Debt Document to be secured with a Junior Lien equally and ratably with all previously existing and future Junior Lien Debt; 
 (2) specifying the name and address of the Secured Debt Representative for such series of Additional Secured Debt for
purposes of Section 7.7; 
 (3) the U.S. Issuer and each other U.S. Guarantor has duly authorized, executed
(if applicable) and recorded (or caused to be recorded) in each appropriate governmental office all relevant agreements, documents, filings and recordations to ensure that the Additional Secured Debt is secured by the Collateral in accordance with
the Security Documents; 
 (4) the U.S. Issuer and the U.S. Guarantors have entered into any supplemental
Security Documents that are necessary to grant to each Secured Debt Representative, for the ratable benefit of the holders of any Secured Debt outstanding on or prior to the date of the incurrence of such Additional Secured Debt, a security interest
in any assets or property of U.S. Issuer and the U.S. Guarantors not otherwise granted under the Security Documents then in effect to the extent that such grantors grant a security interest in such assets to the holders of such Additional Secured
Debt or to any of their representatives (such supplemental Security Documents shall contain such additional customary covenants, representations, conditions (including delivery of customary legal opinions) and other provisions relating to such
additional assets or the granting of such security interest as the Collateral Trustee or any such Secured Debt Representative in respect of such existing Secured Debt may reasonably request (collectively, “Supplemental Security
Documents”)); and 
 (5) the U.S. Issuer has caused a copy of the Additional Secured Debt
Designation to be delivered to each then existing Secured Debt Representative. 
 Although the U.S. Issuer shall be required to deliver a copy
of each Additional Secured Debt Designation, Supplemental Security Document and each Collateral Trust Joinder to each then existing Secured Debt Representative, the failure to so deliver a copy of the Additional Secured Debt Designation,
Supplemental Security Document and/or Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the status of such debt as Additional Secured Debt if the other requirements of this Section 3.8 are complied with.
Each of the Collateral Trustee and the other then existing Secured Debt Representative shall have the right to request that the U.S. Issuer shall provide a copy of any legal opinion of counsel (which may be provided by internal counsel to the U.S.
Issuer) provided to holders of Additional Secured Debt or their Secured Debt Representative as to the Additional Secured Debt being secured by a valid and perfected security interest; provided,

  

 K-44 








 
however, that such legal opinion or opinions need not address any collateral of a type or located in a jurisdiction not previously covered by any legal opinion delivered by or on behalf of
the U.S. Issuer. Notwithstanding the foregoing, nothing in this Agreement will be construed to allow the U.S. Issuer or any other U.S. Guarantor to incur additional Indebtedness or grant additional Liens unless in each case otherwise permitted by
the terms of all applicable Secured Debt Documents. 
 (c) With respect to any Series of Priority Lien Debt, Series of Parity
Lien Debt or Series of Junior Lien Debt incurred after the date of this Agreement, the U.S. Issuer and each U.S. Guarantor agrees to take such actions (if any) (including any acknowledgments by the U.S. Issuer or any of the other U.S. Guarantors of
guarantees or security that are applicable to Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as the case may be, or the execution of any Supplemental Security Documents) as may (subject to Section 5.12) from time to time reasonably
be requested by the Collateral Trustee, any Secured Debt Representative or any Act of Required Debtholders, and enter into any Supplemental Security Documents and such other agreements, amendments, modifications and/or supplements to the then
existing guarantees and Security Documents (or execute and deliver such additional guarantees and Security Documents) as may (subject to Section 5.12) from time to time be reasonably requested by the Collateral Trustee in order to cure any
ambiguity, mistake, defect or inconsistency that does not adversely affect the legal rights under this Agreement of any holder of Secured Obligations (or as contemplated by the following Section 3.8(d)), to ensure that the relevant additional
Priority Lien Obligations, Parity Lien Obligations, or Junior Lien Obligations, as the case may be, are secured by, and entitled to the benefits of, the relevant guarantees and Security Documents, and each Secured Party (by its acceptance of the
benefits hereof) hereby agrees to, and authorizes the Collateral Trustee to enter into, any such Supplemental Security Documents, agreements, amendments, modifications and/or supplements (and additional guarantees and Security Documents).

 (d) All parties hereto acknowledge and agree that, as of the date of this Agreement, the Security Documents as then in effect
may not secure any Priority Lien Obligations or Junior Lien Obligations. At such time (if any) as any Priority Lien Debt or Junior Lien Debt, as the case may be, becomes entitled to the benefits of this Agreement, additional Security Documents shall
be required to be entered into to secure such Priority Lien Debt or Junior Lien Debt, as applicable. Any such Security Documents shall be required to apply only to the Collateral (after giving effect thereto) and shall be in form and substance
substantially the same (although providing Priority Liens or Junior Liens, as applicable, and other appropriate modifications) as the respective Security Documents securing the Parity Lien Obligations (after giving effect to any Supplemental
Security Documents executed for the benefit of the holders of such Parity Lien Obligations) and otherwise in form and substance reasonably satisfactory to the Collateral Trustee and the U.S. Issuer and the U.S. Guarantors party thereto (subject to
Section 5.12).

U.S. Issuer or other applicable U.S. Guarantor, the Collateral Trustee will either (A) be present at and deliver the release at the closing of such transaction or (B) deliver the release under customary escrow arrangements that permit such
contemporaneous payment and delivery of the release. 
 (d) Any amendment or supplement to the provisions of the Security
Documents that releases Collateral will be effective only in accordance with the requirements set forth in this Section 4.1. 
 SECTION 4.2 Delivery of Copies to Secured Debt Representatives. The U.S. Issuer will deliver to each Secured Debt Representative a copy of (a) all Security Documents and (b) each Officers’ Certificate delivered to the

 SECTION 4.3 Collateral Trustee not Required to Serve, File or Record. The Collateral Trustee is not required to serve, file, register
or record any instrument releasing or subordinating its Liens on any Collateral; provided, however, the Collateral Trustee shall authorize the U.S. Issuer or the applicable U.S. Guarantor or any agent or designee thereof (and the same are
hereby authorized) to serve, file, register or record any instrument releasing or subordinating its Liens on any Collateral to the extent such release or subordination is permitted by the terms hereof; and provided, further, that if the U.S. Issuer
or any other U.S. Guarantor shall make a written demand for a termination statement under Section 9-513(c) of the UCC, the Collateral Trustee shall comply with the written request of such U.S. Issuer or U.S. Guarantor to comply with the

 K-47 








 SECTION 5.3 Other Agreements. The Collateral Trustee has accepted and is bound by the
Security Documents executed by the Collateral Trustee as of the date of this Agreement and, as directed by an Act of Required Debtholders or in accordance with Section 3.8, the Collateral Trustee shall execute additional
Security Documents delivered to it after the date of this Agreement; provided, however, that such additional Security Documents do not adversely affect the rights, privileges, benefits and immunities of the Collateral Trustee. Unless it
is a party thereto, the Collateral Trustee will not otherwise be bound by, or be held obligated by, the provisions of any credit agreement, indenture or other agreement governing Secured Debt. 
 SECTION 5.4 Solicitation of Instructions. 
 (a) The Collateral Trustee may at any time solicit written confirmatory instructions, in the form of an Act of Required Debtholders, an Officers’ Certificate or an order of a court of competent
jurisdiction, as to any action that it may be requested or required to take (unless the terms of this Agreement unambiguously mandate the action the Collateral Trustee is required to take under the circumstances then existing), or that it may
propose to take, in the performance of any of its obligations under this Agreement or the other Security Documents. 
 (b) No
written direction given to the Collateral Trustee by an Act of Required Debtholders that in the sole judgment of the Collateral Trustee imposes, purports to impose or might reasonably be expected to impose upon the Collateral Trustee any obligation
or liability not set forth in or arising under this Agreement and the other Security Documents will be binding upon the Collateral Trustee unless the Collateral Trustee elects, at its sole option, to accept such direction. 
 SECTION 5.5 Limitation of Liability. The Collateral Trustee will not be responsible or liable for any action taken or omitted to be
taken by it hereunder or under any other Security Document, except for its own gross negligence or willful misconduct, as determined by a court of competent jurisdiction. 
 SECTION 5.6 Documents in Satisfactory Form. The Collateral Trustee will be entitled to require that all agreements, certificates, opinions, instruments and other documents at any time submitted to
it, including those expressly provided for in this Agreement, be delivered to it in a form and with substantive provisions reasonably satisfactory to it. 
 SECTION 5.7 Entitled to Rely. The Collateral Trustee may seek and conclusively rely upon, and shall be fully protected in conclusively relying upon, any judicial order or judgment, upon any advice,
opinion or statement of legal counsel, independent consultants and other experts selected by it in good faith and upon any certification, instruction, notice or other writing delivered to it by the U.S. Issuer or any other U.S. Guarantor in
compliance with the provisions of this Agreement or delivered to it by any Secured Debt Representative as to the holders of Secured Obligations for whom it acts, without being required to determine the authenticity thereof or the correctness of any
fact stated therein or the propriety or validity of service thereof. The Collateral Trustee may act in reliance upon any instrument comporting with the provisions of this Agreement or any signature reasonably believed by it to be genuine and may
assume that any Person purporting to give notice or receipt or advice or make any statement or execute any document in connection with the provisions hereof or the other Security Documents has been duly authorized to do so. To the extent an
Officers’

  

 K-48 








 
Certificate or opinion of counsel is required or permitted under this Agreement to be delivered to the Collateral Trustee in respect of any matter, the Collateral Trustee may rely conclusively on
Officers’ Certificate or opinion of counsel as to such matter and such Officers’ Certificate or opinion of counsel shall be full warranty and protection to the Collateral Trustee for any action taken, suffered or omitted by it under the
provisions of this Agreement and the other Security Documents. 
 SECTION 5.8 Secured Debt Default. The Collateral
Trustee will not be required to inquire as to the occurrence or absence of any Secured Debt Default and will not be affected by or required to act upon any notice or knowledge as to the occurrence of any Secured Debt Default unless and until it is
directed by an Act of Required Debtholders. 
 SECTION 5.9 Actions by Collateral Trustee. As to any matter not expressly
provided for by this Agreement or the other Security Documents, the Collateral Trustee will act or refrain from acting as directed by an Act of Required Debtholders and will be fully protected if it does so, and any action taken, suffered or omitted
pursuant to hereto or thereto shall be binding on the holders of Secured Obligations. 
 SECTION 5.10 Security or Indemnity
in favor of the Collateral Trustee. The Collateral Trustee will not be required to advance or expend any funds or otherwise incur any financial liability in the performance of its duties or the exercise of its powers or rights hereunder
(including, without limitation, taking any actions under or in respect of control agreements) unless it has been provided with pre-funding, security or indemnity reasonably satisfactory to it (and, for the avoidance of doubt, from parties reasonably
satisfactory to it) against any and all cost, loss, liability or expense which may be incurred by it by reason of taking or continuing to take such action. 
 SECTION 5.11 Rights of the Collateral Trustee. In the event of any conflict between any terms and provisions set forth in this Agreement and those set forth in any other Security Document, the
terms and provisions of this Agreement shall supersede and control the terms and provisions of such other Security Document. In the event there is any bona fide, good faith disagreement between the other parties to this Agreement or any of the other
Security Documents resulting in adverse claims being made in connection with Collateral held by the Collateral Trustee and the terms of this Agreement or any of the other Security Documents do not unambiguously mandate the action the Collateral
Trustee is to take or not to take in connection therewith under the circumstances then existing, or the Collateral Trustee is in doubt as to what action it is required to take or not to take hereunder or under the other Security Documents, it will
be entitled to refrain from taking any action (and will incur no liability for doing so) until directed otherwise, subject to Section 5.10, in writing by a request signed jointly by the parties hereto entitled to give such direction or by order
of a court of competent jurisdiction. 
 SECTION 5.12 Limitations on Duty of Collateral Trustee in Respect of Collateral.

 (a) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Trustee will have no
duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral
Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the
Collateral. The Collateral Trustee will be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded

  

 K-49 








 
treatment substantially equal to that which it accords its own property, and the Collateral Trustee will not be liable or responsible for any loss or diminution in the value of any of the
Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected and maintained by the Collateral Trustee in good faith. 
 (b) The Collateral Trustee will not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the
Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Collateral
Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the U.S. Issuer or any U.S. Guarantor to the Collateral, for insuring the Collateral or for the payment of
taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Collateral Trustee hereby disclaims any representation or warranty to the present and future holders of the Secured Obligations
concerning the perfection of the Liens granted hereunder or in the value of any of the Collateral. 
 SECTION 5.13 Assumption
of Rights, Not Assumption of Duties. Notwithstanding anything to the contrary contained herein: 
 (1) each
of the parties thereto will remain liable under each of the Security Documents (other than this Agreement) to the extent set forth therein to perform all of their respective duties and obligations thereunder to the same extent as if this Agreement
had not be executed; 
 (2) the exercise by the Collateral Trustee of any of its rights, remedies or powers
hereunder will not release such parties from any of their respective duties or obligations under the other Security Documents; and 
 (3) the Collateral Trustee will not be obligated to perform any of the obligations or duties of any of the parties thereunder other than the Collateral Trustee. 
 SECTION 5.14 Hazardous Materials; No Liability for Clean Up; Indemnification. In the event that the Collateral Trustee is required to
acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit of another, which in the Collateral Trustee’s sole discretion may
cause the Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the Collateral Trustee to incur, or be exposed to, any environmental liability or any liability under any other federal,
state or local law, the Collateral Trustee reserves the right, instead of taking such action, either to resign as Collateral Trustee or to arrange for the transfer of the title or control of the asset to a court appointed receiver. The Collateral
Trustee will not be liable to any Person for any environmental liability or any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of the Collateral Trustee’s actions and conduct as
authorized, empowered and directed hereunder or relating to any kind of discharge or release or threatened discharge or release of any hazardous materials into the environment. 
 The U.S. Issuer and the U.S. Guarantors shall defend, indemnify, and hold harmless the Collateral Trustee and its officers, directors, employees and agents from and against any claims, demands,

  

 K-50 








 
penalties, fines, liabilities, settlements, damages, costs, or expenses of whatever kind or nature, known or unknown, contingent or otherwise, arising out of, or in any way related to,
(w) the presence, disposal, release, or threatened release of any Hazardous Materials which are on, from, or affecting the soil, water, vegetation, buildings, personal property, persons, animals, or otherwise; (x) any personal injury
(including wrongful death) or property damage (real or personal) arising out of or related to such Hazardous Materials; (y) any lawsuit brought or threatened, settlement reached, or government order relating to such Hazardous Materials, and/or
(z) any violation of laws, orders, regulations, requirements or demands of government authorities, or any policies or requirements of the Collateral Trustee, which are based upon or in any way related to such Hazardous Materials including,
without limitation, attorney and consultant fees and expenses, investigation and laboratory fees, court costs, and litigation expenses; provided the Collateral Trustee shall not be entitled to indemnification hereunder with respect to the
foregoing clauses (w) through (z) to the extent such liability is found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Collateral Trustee.
For purposes of this paragraph, “Hazardous Materials” includes, without limit, any flammable explosives, radioactive materials, hazardous materials, hazardous wastes, hazardous or toxic substances, or related materials defined in the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (42 U.S.C. Sections 9601, et. seq.), the Hazardous Materials Transportation Act, as amended (49 U.S.C. Sections 5108, et seq.), the Resource Conservation and
Recovery Act, as amended (42 U.S.C. Sections 6901, et seq.), and in the regulations adopted and publications promulgated pursuant thereto, or any other federal, state or local environmental law, ordinance, rule, or regulation. The provisions of this
paragraph shall be in addition to any and all other obligations and liabilities the U.S. Issuer and the U.S. Guarantors may have to any Indemnitee at common law, and shall survive the termination of this Agreement.

appointment of a successor Collateral Trustee as provided in Section 6.2 and the acceptance of such appointment by the successor Collateral Trustee:

 SECTION 6.3 Succession. When the Person so appointed as
successor Collateral Trustee accepts such appointment: 
 (1) such Person will succeed to and become vested with
all the rights, powers, privileges and duties of the predecessor Collateral Trustee, and the predecessor Collateral Trustee will be discharged from its duties and obligations hereunder; and 
 (2) the predecessor Collateral Trustee will (at the expense of the U.S. Issuer) promptly transfer all Liens and collateral
security and other property of the Trust Estates within its possession or control to the possession or control of the successor Collateral Trustee and will execute instruments and assignments as may be necessary or desirable or reasonably requested
by the successor Collateral Trustee to transfer to the successor Collateral Trustee all Liens, interests, rights, powers and remedies of the predecessor Collateral Trustee in respect of the Security Documents or the Trust Estates. 
 Thereafter the predecessor Collateral Trustee will remain entitled to enforce the immunities granted to it in Article 5 and the provisions of
Sections 7.10 and 7.11. 
 SECTION 6.4 Merger, Conversion or Consolidation of Collateral Trustee. Any Person into
which the Collateral Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Collateral Trustee shall be a party, or any Person succeeding to all or
substantially all the corporate trust business of the Collateral Trustee shall be the successor of the Collateral Trustee pursuant to Section 6.3, provided that (i) without the execution or filing of any paper with any party hereto
or any further act on the part of any of the parties hereto, except where an instrument of transfer or assignment is required by law to effect such succession, anything herein to the contrary notwithstanding, such Person satisfies the eligibility
requirements specified in clauses (1) through (4) of Section 6.2 and (ii) prior to any such merger, conversion or consolidation, the Collateral Trustee shall have notified the U.S. Issuer, each Priority Lien Representative, each
Parity Lien Representative and each Junior Lien Representative thereof in writing.

 K-52 








 (2) no amendment or supplement that reduces, impairs or adversely affects
the right of any holder of Secured Obligations:

described as subject to an Act of Required Debtholders or direction by the Required Parity Lien Debtholders or Required Junior Lien Debtholders (or amends the provisions of this clause (2) or the definition of “Act of Required

 (2) any mortgage or other Security Document that secures Parity Lien Obligations (but not Priority Lien Obligations) may be
amended or supplemented with the approval of the Collateral Trustee acting as directed in writing by the Required Parity Lien

Debtholders (or such other number or percentage of holders of Parity Lien Debt as may be required under the applicable Parity Lien Documents), unless such amendment or supplement would not be
permitted under the terms of this Agreement or the other Priority Lien Documents; 
 (3) any mortgage or other
Security Document that secures Priority Lien Obligations (but not Parity Lien Obligations) may be amended or supplemented with the approval of the Collateral Trustee acting as directed in writing by the Required Priority Lien Debtholders (or such
other number or percentage of holders of Priority Lien Debt as may be required under the applicable Priority Lien Documents), unless such amendment or supplement would not be permitted under the terms of this Agreement or the other Parity Lien
Documents; and 
 (4) any amendment or waiver of, or any consent under, any provision of this Agreement or any
mortgage or other Security Document that secures Priority Lien Obligations or that secures Parity Lien Obligations (to the extent otherwise permitted under this Section 7.1) will apply automatically to any comparable provision of any comparable
Junior Lien Document without the consent of or notice to any holder of Junior Lien Obligations and without any action by the U.S. Issuer or any U.S. Guarantor or any holder of Junior Lien Obligations. 
 (c) The Collateral Trustee will not enter into any amendment or supplement unless it has received an Officers’ Certificate to the

Trustee will be entitled to receive an opinion of counsel of the U.S. Issuer (which may be provided by internal counsel to the U.S. Issuer) to the effect that the execution of such document is authorized or permitted hereunder, and with respect to
amendments adding Collateral, an opinion of counsel of the U.S. Issuer (which may be provided by internal counsel to the U.S. Issuer) addressing customary perfection, and if such additional Collateral consists of equity interests of any Person,
priority matters with respect to such additional Collateral.

Representatives agree that each Security Document that secures Secured Obligations will include the following language:

the provisions of the U.S. Collateral Trust Agreement, dated as of [—], among U.S. Issuer, the U.S. Guarantors from time to time party thereto, the Priority Lien Representatives from time to time
party thereto, the Parity Lien Representatives from time to time party thereto, the Junior Lien Representatives from time to time party thereto, The Bank of New York Mellon, as Trustee under the Indenture (as defined therein) and U.S. Bank National

Collateral Trust Agreement and this Agreement, the terms of the Collateral Trust Agreement will govern.”

drawn), plus (2) other than in connection with an exercise of remedies, the aggregate unfunded commitments to extend credit which, when funded, would constitute Indebtedness of such Series of Secured Debt. Following and in accordance

Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Secured Debt Documents for the benefit of the holders of Secured
Obligations (it being expressly agreed that the Collateral Trustee has no responsibility to monitor, protect or perfect any such Liens or benefits).

Obligations in accordance with Section 3.8, there shall no longer be a Discharge of Priority Lien Obligations for purposes of this Agreement. 
 (b) Subject to Section 7.21(a) above, this Agreement, including the subordination provisions hereof, will be reinstated if at any time any payment or distribution in respect of any of the Parity Lien
Obligations is rescinded or must otherwise be returned in an Insolvency or Liquidation Proceeding or otherwise by any holder of Parity Lien Obligations or Parity Lien Representative or any representative of any such party (whether by demand,

Section 3.4. Until so delivered, such proceeds will be held by that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may be, for the benefit of the holders of the Parity Lien Obligations and other Obligations
secured by a Parity Lien. For the avoidance of doubt, if a Discharge of Parity Lien Obligations occurs prior to the termination of this Agreement, to the extent that additional Parity Lien Obligations are incurred in accordance with

the commencement of any such case, as provided in this Agreement. 
 SECTION 7.23 Rights and Immunities of Secured Debt
Representatives. The Trustee will be entitled to all of the rights, protections, immunities and indemnities set forth in the Indenture and any future Secured Debt Representative will be entitled to all of the rights, protections, immunities and
indemnities set forth in the credit agreement, indenture or other agreement governing the applicable Secured Debt with respect to which such Person will act as representative, in each case as if specifically set forth herein. In no event will any

natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Collateral Trustee shall use reasonable efforts which are consistent
with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 
 SECTION
7.25 U.S.A. Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Collateral Trustee, like all financial institutions and in order to help fight the funding of terrorism and money
laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Collateral Trustee. The parties to this Agreement agree that they will provide
