 The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent
(if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as
Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes. 
 Section 2.05 Holder Lists. 
 The Trustee will preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of all Holders and shall otherwise comply with TLA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each interest payment
date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA
§ 312(a).

 (2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.11, 4.10,4.15
and 9.05 hereof). 
 (3) The Registrar will not be required to register the transfer of or exchange of any Note selected for

 37 

 (5) Neither the Registrar nor the Company will be required:

day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; 
 (B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be
affected by notice to the contrary.

 Section 2.07 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the
Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s
requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating
agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 
 Every
replacement Note is an additional obligation of the Company and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 
 Section 2.08 Outstanding Notes. 
 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by
the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of
the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof. 
 If a Note is replaced pursuant to Section 2.07 hereof, such Note ceases to be outstanding unless the Trustee receives proof satisfactory to it that
the replaced Note is held by a protected purchaser. 
  

 38 

 If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be
outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 
 Section 2.09 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on
any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned will be so disregarded. 
 Section 2.10 Temporary Notes. 
 Until certificates representing Notes are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate
for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 
 Section 2.11 Cancellation. 
 The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act and under
applicable Canadian law). Certification of the destruction of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

 Section 2.12 Defaulted Interest. 
 If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in writing of the
amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be
less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company)
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.

or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for
redemption or purchase also apply to portions of Notes called for redemption or purchase.

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 12 hereof. 
 The notice will identify the Notes to be redeemed and will state: 
 (1) the redemption date;

 (2) the redemption price; 
  

 40 

 (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; and 
 (8) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Notes. 
 At the Company’s request, the Trustee will give the notice of
redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 
 Section 3.04 Effect of Notice of

Redemption or Purchase Price. 
 One Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or

the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest and Additional Interest, if any, on, all Notes to be redeemed or
purchased. 
 If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest
will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid
interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure
of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in
each case at the rate provided in the Notes and in Section 4.01 hereof.

 The Company may, at its option, at any time redeem in whole but not in part the Notes at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if
any, to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date) if it has become obligated to pay any Additional Amounts (as defined in
Section 3.09 hereof) in respect of the Notes as a result of: 
 (1) any change in or amendment to the laws (or
regulations promulgated thereunder) of any Taxing Jurisdiction, or 
 (2) any change in or amendment to any official position
regarding the application or interpretation of such laws or regulations, which change or amendment is announced or is effective on or after the date of original issuance of the Notes. 
 Section 3.09 Additional Amounts 
 All amounts paid or credited by the Company under or with
respect to the Notes, or by any Guarantor pursuant to its Note Guarantee, will be made free and clear of and without withholding or deduction for or on account of any Taxes imposed or levied by or on behalf of a Taxing Jurisdiction, unless the
Company or any Guarantor is required by law to withhold or deduct Taxes from any payment made under or with respect to the Notes or by the interpretation or administration thereof. If, after the date on which Notes are first issued and authenticated
under this Indenture, the Company or any Guarantor is so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Notes, the Company or such Guarantor will pay to each Holder of Notes
that are outstanding on the date of the required payment, such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by such holder (including the Additional Amounts) after such withholding or
deduction will not be less than the amount such Holder would have received if such Taxes had not been withheld or deducted; provided that no Additional Amounts will be payable with respect to a payment made to a Holder of the Notes (each of the
following, an “Excluded Holder”): 
 (1) with whom the Company does not deal at arm’s length (within the
meaning of the Income Tax Act (Canada)) at the time of making such payment or credit; 
 (2) on which such Taxes have been
imposed because of the existence of any present or former connection between the relevant holder or beneficial owner (or between a fiduciary, settler, beneficiary, or member of, or possessor of power over, the relevant holder or beneficial owner, if
the relevant holder or beneficial owner is an estate, nominee, trust, or partnership) and the Taxing Jurisdiction (other than the mere receipt of such payment or the ownership or holding of such note), including without limitation such holder or
beneficial owner being a resident, domiciliary or national of, or engaged in business or maintaining a permanent establishment in, the Taxing Jurisdiction; 
 (3) on which such estate, inheritance, gift, sales, excise, transfer, personal property tax or similar tax have been imposed; 
  

 43 

 (4) on which such Taxes are imposed or withheld by reason of the failure to comply by the
Holder or the beneficial owner of a note with a request by the Company addressed to the Holder or such beneficial owner (i) to provide information concerning the nationality, residence, identity, entitlement to treaty benefits or present or
former connection with a Taxing Jurisdiction of the Holder or such treaty benefits or present or former connection with a Taxing Jurisdiction of the holder or such beneficial owner or (ii) to make any declaration or other similar claim or
satisfy any certification, information or reporting requirement, which, in the case of (i) or (ii), is required or imposed by a statue, treaty, regulation or administrative practice of the Taxing Jurisdiction as a precondition to exemption from
all or part of such Taxes; 
 (5) which failed to duly and timely comply with a timely request by the Company to provide
information, documents, certification or other evidence concerning such Holder’s nationality, residence, entitlement to treaty benefits, identity or connection with a Taxing Jurisdiction or any political subdivision or authority thereof, if and
to the extent that due and timely compliance with such request could have resulted in the reduction or elimination of any Taxes as to which Additional Amounts would otherwise have been payable to such Holder of Notes but for this clause (5);

 (6) which is a fiduciary, a partnership or not the beneficial owner of any payment on a note, if and to the extent that any
beneficiary or settlor of such fiduciary, any partner of such partnership or the beneficial owner of such payment (as the case may be) would not have been entitled to receive Additional Amounts with respect to such payment if such beneficiary,
settlor, partner or beneficial owner had been the holder of such note; or 
 (7) any combination of the foregoing clauses
(1) through (6). 
 Neither the Company nor a Guarantor will be required to pay Additional Amounts if the payment could have been made
without deduction or withholding if, when presentation is required, the beneficiary of the payment had presented the Note for payment within 30 days after the date on which such payment or such Note became due and payable or the date on which
payment thereof is duly provided for, whichever is later (except to the extent that such beneficiary would have been entitled to Additional Amounts had the Note been presented on the last day of the 30-day period). 
 The Company and the Guarantors will also: 
 (1) make such withholding or deduction, and 
 (2) remit the full amount deducted or withheld
to the relevant authority in accordance with applicable law. 
 The Company and the Guarantors will furnish to the Trustee, or cause to be
furnished to the Trustee, within 30 days after the date the payment of any Taxes is due pursuant to applicable law, certified copies of tax receipts evidencing that such payment has been made by the Company or any such Guarantor or other evidence of
such payment satisfactory to the Trustee. The trustee shall make such evidence available upon the written request of any Holder of the Notes that are outstanding on the date of any such withholding or deduction. The Company and the Guarantors will
indemnify and hold harmless each Holder of Notes that are outstanding on the date of the required payment (other than an Excluded Holder) and upon written request reimburse each such Holder for the amount of: 
 (1) any Taxes so levied or imposed by or on behalf of a Taxing Jurisdiction and actually paid by such Holder as a result of payments made
under or with respect to the Notes and any liability (including penalties, interest and expense) arising therefrom or with respect thereto, and 
  

 44 

 (2) any Taxes (other than Taxes on such Holder’s profits or net income) imposed with
respect to any reimbursement under clause (1) above so that the net amount received by such Holder after such reimbursement will not be less than the net amount such Holder would have received if Taxes on such reimbursement had not been
imposed. 
 At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable, if the Company or
any such Guarantor becomes obligated to pay Additional Amounts with respect to such payment, the Company or such Guarantor will deliver to the Trustee an Officers’ Certificate stating the fact that such Additional Amounts will be payable, and
the amounts so payable and will set forth such other information as is necessary to enable the Trustee to pay such Additional Amounts to the Holders of the Notes on the payment date. Whenever in this Indenture there is mentioned, in any context:

 (1) the payment of principal (and premium, if any); 
 (2) purchase prices in connection with a repurchase of Notes; 
 (3) interest; or 
 (4) any other amount payable on or with respect to any of the Notes, 
 such mention 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 3.10 Mandatory Redemption. 
 The Company is not required to make mandatory redemption or sinking fund payments
with respect to the Notes. 
 Section 3.11 Offer to Purchase by Application of Excess Proceeds. 
 In the event that, pursuant to Section 4.10 hereof, the Company is required to commence an offer to all Holders to purchase Notes (an “Asset
Sale Offer”), it will follow the procedures specified below. 
 The Asset Sale Offer shall be made to all Holders and all holders of
other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open
for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days
after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro
rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest
payments are made. 
 If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any
accrued and unpaid interest and Additional 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. 
  

 45 

 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the
Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the
Asset Sale Offer, will state: 
 (1) that the Asset Sale Offer is being made pursuant to this Section 3.11 and
Section 4.10 hereof and the length of time the Asset Sale Offer will remain open; 
 (2) the Offer Amount, the purchase
price and the Purchase Date; 
 (3) that any Note not tendered or accepted for payment will continue to accrue interest;

 (4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale
Offer will cease to accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note purchased pursuant to
an Asset Sale Offer may elect to have Notes purchased in integral multiples of $1,000 only; 
 (6) that Holders electing to
have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company,
a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date; 
 (7) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 
 (8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the
Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such
adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or integral multiples thereof, will be purchased); and 
 (9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered (or transferred by book-entry transfer). 
 On or before the Purchase Date, the Company will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver
or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this
Section 3.11. The Company, the Depositary or the Paying Agent, as the 
  

 46 

 case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will
authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered
by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date. 
 Other
than as specifically provided in this Section 3.11, any purchase pursuant to this Section 3.11 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

 Section 4.01 Payment of Notes. 
 The Company will pay or cause to be paid the principal of,
premium, if any, and interest and Additional Interest, if any, on, the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest and Additional Interest, if any will be considered paid on the date due if

 The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however,

required to file those reports with the SEC.

the Notes. 
 Section 4.06 Stay, Extension and Usury Laws. 
 The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company 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

principal at the Stated Maturity related to such payment of interest or principal; or 
 (4) make any Restricted Investment

(2) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment
had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09 hereof; and 
 (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted

declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of this Indenture; 
 (2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than
to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to the Company; provided that the amount of any such net cash proceeds
that are utilized for any such Restricted Payment will be excluded from clause (3)(B) of Section 4.07 hereof; 
 (3)
the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness of the Company or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee with the net cash proceeds from a
substantially concurrent incurrence of Permitted Refinancing Indebtedness; 
 (4) the payment of any dividend (or, in the case
of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary of the Company to the holders of its Equity Interests on a pro rata basis; 
 (5) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted
Subsidiary of the Company held by any current or former officer, director or employee of the Company or any of its Restricted Subsidiaries pursuant to any equity subscription agreement, stock option agreement, shareholders’ agreement or similar
agreement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $3.0 million in any twelve-month period; 
  

 51 

 (6) the repurchase, redemption or other acquisition or retirement for value of any Equity
Interests of AMI held by any current or former officer, director or employee of AMI in connection with the Acquisition; 
 (7)
the repurchase of Equity Interests deemed to occur upon the exercise of stock options to the extent such Equity Interests represent a portion of the exercise price of those stock options; 
 (8) the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the
Company or any Restricted Subsidiary of the Company issued on or after the date of this Indenture in accordance with the Fixed Charge Coverage Ratio test described in Section 4.09 hereof; or 
 (9) other Restricted Payments in an aggregate amount not to exceed $25.0 million since the date of this Indenture. 
 The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued by this Section 4.07
will be determined by the Board of Directors of the Company whose resolution with respect thereto will be delivered to the Trustee. The Board of Directors’ determination must be based upon an opinion or appraisal issued by an accounting,
appraisal or investment banking firm of national standing if the Fair Market Value exceeds $10.0 million. 
 Section 4.08 Dividend and Other Payment
Restrictions Affecting Subsidiaries. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or
pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; 
 (2) make loans or advances to the Company
or any of its Restricted Subsidiaries; or 
 (3) sell, lease or transfer any of its properties or assets to the Company or any

restrictions existing under or by reason of: 
 (1) agreements governing Existing Indebtedness and Credit Facilities 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;

  

 52 

 (2) this Indenture, the Notes and the Note Guarantees; 
 (3) applicable law, rule, regulation or order; 
 (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in
effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the
properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; 

(5) non-assignment or change in control provisions in contracts and licenses entered into in the ordinary course of business;

 (6) the license of any intellectual property of the Company or any of its Restricted Subsidiaries;

 (10) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted

 (12) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements,
sale-leaseback agreements, stock sale agreements and other similar agreements entered into with the approval of the Company’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements; and

 (13) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered
into in the ordinary course of business. 
 Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur 
  

 53 

 Indebtedness (including Acquired Debt) or issue Disqualified Stock, and the Guarantors may incur Indebtedness (including
Acquired Debt) or issue preferred stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock or such preferred stock is issued, as the case may be, would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period; 
 (b) The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively,
“Permitted Debt”): 
 (1) the incurrence by the Company and any Guarantor of Indebtedness and letters
of credit under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (l)(with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its
Restricted Subsidiaries thereunder) not to exceed $375.0 million less the aggregate amount of all repayments, optional or mandatory, of the principal of any term Indebtedness under a Credit Facility (other than repayments that are
concurrently refunded or refinanced or repayment of Indebtedness of AMI at the date of issuance of the Initial Notes) that have been made by the Company or any of its Restricted Subsidiaries since the date of this Indenture and less the
aggregate amount of all commitment reductions with respect to any revolving credit borrowings under a Credit Facility that have been made by the Company or any of its Restricted Subsidiaries since the date of this Indenture; 
 (2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness; 
 (3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Initial Notes and the related Note Guarantees to
be issued on the date of this Indenture and the Exchange Notes and the related Note Guarantees to be issued pursuant to the Registration Rights Agreement; 
 (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the
purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate
principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $10.0 million at any time outstanding;

 (5) Indebtedness of a Subsidiary incurred and outstanding on or prior to the date on which such Subsidiary was acquired by
the Company (other than Indebtedness incurred in contemplation of, or in connection with, the transaction or series of related transactions pursuant to which such Subsidiary became a Subsidiary of or was otherwise acquired by the Company); provided,
however, that for any such Indebtedness outstanding at any time under this clause (5), on the date that such Subsidiary is acquired by the Company, the Company would have been able to incur $1.00 of additional Indebtedness pursuant to clause
(a) above after giving effect to the incurrence of such Indebtedness pursuant to this clause (5). 
  

 54 

 (6) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted
Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred
under clause (a) above or clauses (2), (3), (4), (5), (6) or (13) of this Section 4.09(b); 
 (7) the
incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Wholly-Owned Restricted Subsidiaries; provided, however, that: 
 (A) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness
must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, 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 Wholly-Owned 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 Wholly-Owned Restricted Subsidiary of the Company, 

will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that
was not permitted by this clause (7); 
 (8) the issuance by any of the Company’s Restricted Subsidiaries to the Company
or to any of its Wholly-Owned Restricted Subsidiaries of shares of preferred stock; provided, however, that: 
 (A) any
subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Wholly-Owned Restricted Subsidiary of the Company; and 
 (B) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Wholly-Owned Restricted
Subsidiary of the Company, 
 will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary
that was not permitted by this clause (8); 
 (9) the incurrence by the Company or any of its Restricted Subsidiaries of
Hedging Obligations in the ordinary course of business; 
 (10) the guarantee by the Company or any of the Guarantors of
Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu
with the Notes, then the Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, performance and surety bonds in the ordinary course
of business; 
  

 55 

 (12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; and 
 (13) the incurrence by the Company or the Guarantors of additional Indebtedness in an aggregate principal amount at any time outstanding,
not to exceed $35.0 million. 
 For purposes of determining compliance with this Section 4.09, in the event that an item of proposed
Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in Sections 4.09(b)(l) through (13) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to
classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the
date on which Notes are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of
interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in
accounting principles, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for
purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued. Notwithstanding any other provision of this Section 4.09,
the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 The amount of any Indebtedness outstanding as of any date will be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with the original issue discount; 
 (2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 
 (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 
 (A) the Fair Market Value of such assets at the date of determination; and 
 (B) the amount of the Indebtedness of the other Person. 
 Section 4.10 Asset Sales. 
 The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may be)
receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
  

 56 

 (2) at least 75% of the consideration received in the Asset Sale by the Company or such
Restricted Subsidiary is in the form of cash or Cash Equivalents or a combination of the foregoing. For purposes of this provision (and not for the purpose of the definition of Net Proceeds) 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 agreement that
releases the Company or such Restricted Subsidiary from further liability; 
 (B) any securities, Notes or other obligations
received by the Company or any such Restricted Subsidiary from such transferee that are converted within 90 days of such Asset Sale by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion; and

 (C) any stock or assets of the kind referred to in clauses (2) or (4) of the next paragraph of this
Section 4.10. 
 Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted
Subsidiary, as the case may be) may apply such Net Proceeds at its option: 
 (1) to repay Senior Debt and to correspondingly
reduce commitments with respect thereto; 
 (2) to acquire Business Assets or any Capital Stock of a Permitted Business, if,
after giving effect to any such acquisition of Capital Stock or Business Assets, such Capital Stock or Business Assets become part of or held or owned by a Guarantor; 
 (3) to make a capital expenditure; or 
 (4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business. 
 Pending the final application of any Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

 Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second paragraph of this Section 4.10 will
constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $15.0 million, within 20 days thereof, the Company will make an Asset Sale Offer to all Holders of Notes and all holders of other Indebtedness that
is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets in accordance with Section 3.11 hereof to purchase the
maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest
and Additional Interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by
this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds 
  

 57 

 the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to
be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 The Company will comply with the requirements of Rule 14e-l 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 an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with Section 3.11 hereof or this Section 4.10, the Company will comply with the applicable securities laws and regulations
and will not be deemed to have breached its obligations under Section 3.11 hereof or this Section 4.10 by virtue of such compliance. 
 Section 4.11 Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of
its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that
would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (2) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause
(1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$25.0 million, an opinion as to the fairness to the Company or such Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 
 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.1 l(a)
hereof: 
 (1) any employment agreement, employee benefit plan, officer or director indemnification agreement, consulting
agreement, severance agreement, insurance policy or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto, and, with respect to consulting
agreements only, the terms of which have been approved by the audit committee of the Board of Directors of the Company; 
 (2)
transactions between or among the Company and/or its Restricted Subsidiaries; 
  

 58 

 (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 directors’ fees to Persons who are not otherwise Affiliates of the Company; 
 (5) any transaction pursuant to any contract in existence on the date of the original issuance of the Notes; 
 (6) any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company; and 
 (7) Restricted Payments that do not violate Section 4.07 hereof. 
 Section 4.12 Liens. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness or
Attributable Debt upon any of their respective property or assets, now owned or hereafter acquired, unless all payments due under this Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured until such time
as such obligations are no longer secured by a Lien. 
 Section 4.13 Business Activities. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such
extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. 
 Section 4.14
Corporate Existence. 
 Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect: 
 (1) its corporate existence, and the corporate, partnership or other existence of each of its
Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and 
 (2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 
 Section 4.15 Offer to Repurchase Upon Change of Control. 
 (a) Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of Control Offer”) to each Holder to repurchase
all or any part (equal to $2,000 or an integral multiple of $1,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate 
  

 59 

 principal amount of Notes repurchased plus accrued and unpaid interest and Additional 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 twenty days following any
Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 
 (1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for
payment; 
 (2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days
from the date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that any Note not tendered
will continue to accrue interest; 
 (4) that, unless the Company defaults in the payment of the Change of Control Payment,
all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to
the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 
 (6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the
second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is
withdrawing his election to have the Notes purchased; and 
 (7) that Holders whose Notes are being purchased only in part
will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. 
 The Company will comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent
those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Sections 3.11 or
4.15 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.11 hereof or this Section 4.15 by virtue of such compliance. 
 (b) On the Change of Control Payment Date, the Company will, to the extent lawful: 
 (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 
  

 60 

 (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together
with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 The Paying Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new
Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

 Prior to complying with any of the provisions of this Section 4.15, but in any event within 90 days following a Change of Control,
the Company will either repay all outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing outstanding Senior Debt to permit the repurchase of Notes required by this Section 4.15. 
 (c) Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control Offer upon a Change
of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and Section 3.11 hereof and purchases all Notes properly
tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable redemption price. 
 Section 4.16 No Layering of Debt. 
 The Company will not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is contractually subordinate or junior in right of payment to any Senior Debt of the Company and senior
in right of payment to the Notes. No Guarantor will incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is contractually subordinate or junior in right of payment to the Senior Debt of such Guarantor and
senior in right of payment to such Guarantor’s Note Guarantee. No such Indebtedness will be considered to be senior by virtue of being secured on a first or junior priority basis. 
 Section 4.17 Limitation on Sale and Leaseback Transactions. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the
Company or any Guarantor may enter into a sale and leaseback transaction if: 
 (1) the Company or that Guarantor, as
applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the Fixed Charge Coverage Ratio test in Section 4.09(a) hereof and (b) incurred a Lien
to secure such Indebtedness pursuant to the provisions of Section 4.12 hereof; 
 (2) the gross cash proceeds of that
sale and leaseback transaction are at least equal to the Fair Market Value, as determined in good faith by the Board of Directors of the Company and set forth in an Officers’ Certificate delivered to the Trustee, of the property that is the
subject of that sale and leaseback transaction; and 
 (3) the transfer of assets in that sale and leaseback transaction is
permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.10 hereof. 
  

 61 

 Section 4.18 Payments for Consent. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or
for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the
Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.19 Additional Note Guarantees. 
 If the Company or any of its Restricted Subsidiaries
acquires or creates another Restricted Subsidiary after the date of this Indenture and that newly acquired or created Restricted Subsidiary Guarantees any Indebtedness of the Company or of any its Restricted Subsidiaries, including the Credit
Agreement, then that newly acquired or created Restricted Subsidiary will become a Guarantor and execute a Note Guarantee pursuant to a supplemental indenture in form and substance satisfactory to the Trustee and deliver an Opinion of Counsel to the
trustee within 10 business days of the date on which it was acquired or created to the effect that such Supplemental Indenture has been duly authorized, executed and delivered by that Restricted Subsidiary and constitutes a valid and binding
agreement of that Restricted Subsidiary enforceable in accordance with its terms (subject to customary exceptions). The form of such Note Guarantee is attached as Exhibit F hereto. 
 Section 4.20 Designation of Restricted and Unrestricted Subsidiaries. 
 The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a
Default; provided that in no event will the business currently operated by the Hungarian Subsidiary be transferred to or held by an Unrestricted Subsidiary. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate
Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount
available for Restricted Payments under Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at
that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not
cause a Default. 
 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing
with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by
Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any
Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in
default of such covenant. The Board of Directors of the 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 (i) such Indebtedness is permitted under Section 4.09 hereof, calculated
on a proforma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (ii) no Default or Event of Default would be in existence following such designation.

 If on any date following the date of this Indenture: 
 (1) the Notes are rated Baa3 or better by Moody’s and BBB- or better by S&P; and

longer be applicable to the Notes.

Guarantee now exists, or is created after the date of this Indenture, if that default: 
 (A) is caused by a failure to pay
principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 
 (B) results in the acceleration of such Indebtedness prior to its express maturity, 
 and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has

 Section 6.02 Acceleration. 
 In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any
group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and
is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. 
 Upon any such declaration, the Notes shall become due and payable immediately. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Additional Interest, if any, that
has become due solely because of the acceleration) have been cured or waived. 
  

 66 

 If an Event of Default occurs on or after April 1, 2009 by reason of any willful action (or
inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Notes pursuant to Section 3.07 hereof,
then, upon acceleration of the Notes, an equivalent premium shall also become and be immediately due and payable, to the extent permitted by law, anything in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default
occurs prior to April 1, 2009 by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding the prohibition on redemption of the Notes prior to such date, then, upon
acceleration of the Notes, an additional premium shall also become and be immediately due and payable, to the extent permitted by law, in an amount, for each of the years beginning on April 1 of the years set forth below, as set forth below
(expressed as a percentage of the principal amount of the Notes on the date of payment that would otherwise be due but for the provisions of this sentence): 
  

				
	 Year
	  	Percentage	 
	 2006
	  	7.750	%
	 2007
	  	7.104	%
	 2008
	  	6.4583	%

 Section 6.03 Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium and Additional
Interest, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The Trustee may
maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default
shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults. 
 Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default
and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Additional Interest, if any, or interest on, the Notes (including in connection with an offer to purchase); provided,
however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon. 
 Section 6.05 Control by Majority. 
 Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial
to the rights of other Holders of Notes. 
  

 67 

 Section 6.06 Limitation on Suits. 
 Except to enforce the right to receive payment of principal, premium, if any, or interest or Additional Interest, if any, when due, no Holder of a Note
may pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) such Holder gives to the Trustee written
notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in aggregate principal amount of the then
outstanding Notes make a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders offer and, if
requested, provide to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; 
 (4) the Trustee has not complied with the request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a
direction inconsistent with such request. 
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a
Note or to obtain a preference or priority over another Holder of a Note. 
 Section 6.07 Rights of Holders of Notes
to Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of
principal, premium and Additional Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on
or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08
Collection Suit by Trustee. 
 If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing,
the Trustee is authorized to recover judgment in its own name and as Trustee of an express trust against the Company for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on, the Notes and
interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel. 
 Section 6.09 Trustee May File Proofs of Claim. 
 The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor
upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and 
  

 68 

 distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by
a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes
or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities. 
 If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in
the following order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.07
hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any,
and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Additional Interest, if any and interest, respectively; and 
 Third: to the Company or to such party as a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
 Section 6.11 Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
aggregate principal amount of the then outstanding Notes.

 ARTICLE 7 
 TRUSTEE 
 Section 7.01 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use

 (b) Except during the continuance of an Event of Default: 
 (1) the duties of the Trustee
will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this

 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and
opinions to determine whether or not they conform to the requirements of this Indenture.

 (1)
this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

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

document.

both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written advice of such counsel or any

 Section 7.03 Individual Rights of Trustee. 
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of
the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee
(if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 
 Section 7.04 Trustee’s Disclaimer. 
 The Trustee will not be responsible for and makes no

mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium or 
  

 71 

 Additional Interest, if any, or interest on, any Note, the Trustee may withhold the notice if and so long as a committee
of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 
 Section 7.06
Reports by Trustee to Holders of the Notes. 
 (a) Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, and for so long as Notes remain outstanding, the Trustee will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA §
313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail all reports as required by TIA § 313(c).

 (b) A copy of each report at the time of its mailing to the Holders of Notes will be mailed by the Trustee to the Company and filed by the
Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the Notes are listed on any stock exchange. 
 Section 7.07 Compensation and Indemnity. 
 (a)
The Company will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express

compensation, disbursements and expenses of the Trustee’s agents and counsel.

Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against
the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of
any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have
separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. 
 (c) The obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture.

 (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee will have a Lien
prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture. 
 (e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(7) or (8) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
  

 72 

 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable.

 (a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. 
 (b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 hereof; 
 (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy
Law; 
 (3) a custodian or public officer takes charge of the Trustee or its property; or 
 (4) the Trustee becomes incapable of acting. 
 (c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office,
the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or

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

 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01
Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may at any time, at the option of its Board of Directors
evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 
 Section 8.02 Legal Defeasance and Discharge. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “‘Legal Defeasance”}.
For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed
to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note
Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged
hereunder: 
 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest
or premium and Additional Interest, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 
  

 74 

 (2) the Company’s obligations with respect to such Notes under Article 2 and
Section 4.02 hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Company’s and the Guarantors’ obligations in connection therewith; and 
 (4) this Article 8. 
 Subject to compliance with this Article 8, the Company may exercise its option under this Section 

	8.02	notwithstanding the prior exercise of its option under Section 8.03 hereof. 

 Section 8.03 Covenant Defeasance. 
 Upon the Company’s exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in
Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20, 4.21 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in
Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders
(and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company 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 Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(5) hereof will not
constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 
 (1) the Company must irrevocably deposit, or cause to be deposited, with the Trustee, in trust, for the benefit of the Holders of the
Notes, cash in U.S. dollars, non-callable Government Securities, or a combination 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 and Additional Interest, 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 Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date; 
 (2) in the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of: 
  

 75 

 (A) U.S. counsel reasonably acceptable to the Trustee confirming that (i) the
Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of this Indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect
that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding Notes will not recognize gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to 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; and 
 (B) Canadian counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize gain or loss for Canadian federal, provincial or territorial income tax purposes as a
result of such Legal Defeasance and will be subject to Canadian federal, provincial or territorial income tax (including withholding tax) on the same amounts, in the same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred; 
 (3) in the case of an election under Section 8.03 hereof, the Company must deliver to the
Trustee an Opinion of:

case if such Covenant Defeasance had not occurred; and 
 (B) Canadian counsel reasonably acceptable to the Trustee confirming
that the Holders of the outstanding Notes will not recognize gain or loss for Canadian federal, provincial or territorial income tax purposes as a result of such Covenant Defeasance and will be subject to Canadian federal, provincial or territorial
income tax (including withholding 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; and 
 (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 the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the
Company or any Guarantor is bound; 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
  

 76 

 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion

 Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject
to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”)
pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and Additional Interest, if any, and interest, but such money
need not be segregated from other funds except to the extent required by law. 
 The Company will pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes. 
 Notwithstanding anything in this Article 8 to the
contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to Company. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium or Additional
Interest, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium or Additional Interest, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the
Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as Trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in
the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s 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 
  

 77 

 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 Company makes any payment of principal of, premium or Additional Interest, if any, or interest on, any Note following the reinstatement of its
obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 
 Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes or
the Note Guarantees without the consent of any Holder of Note: 
 (1) to cure any ambiguity, defect or inconsistency;

 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
 (3) to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of the Notes and Note Guarantees
by a successor to the Company 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 of the Notes or that does not adversely affect the legal rights hereunder of any Holder; 
 (5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 
 (6) to conform the text of this Indenture or the Notes to any provision of the “Description of Notes” section of the
Company’s Offering Circular dated March 16, 2006, relating to the initial offering of the Notes, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this
Indenture, the Note Guarantees or the Notes; 
 (7) to provide for the issuance of Additional Notes in accordance with the
limitations set forth in this Indenture as of the date hereof; 
 (8) to allow any Guarantor to execute a supplemental
indenture and/or a Note Guarantee with respect to the Notes; or 
 (9) to provide for the appointment of a Canadian co-trustee
if required to qualify the Exchange Notes under a prospectus for purposes of applicable Canadian law and to make any consequential amendments to the Indenture that may be necessary or desirable to give effect to such appointment, including without
limitation, adding to or changing any of the provisions of this Indenture for the benefit of such Canadian co-trustee or as may be necessary or desirable to provide for and facilitate the administration of the trusts hereunder by two trustees.

 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or
supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and 
  

 78 

 the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities
under this Indenture or otherwise. 
 Section 9.02 With Consent of Holders of Notes. 
 Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation,
Section 3.11, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if
any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of
Default (other than a Default or Event of Default in the payment of the principal of, premium or Additional Interest, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture or the Notes 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, Additional Notes, if any)
voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be
“outstanding” for purposes of this Section 9.02. 
 Upon the request of the Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee
of the documents described in Section 7.02 hereof, the Trustee will join with the Company 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 be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it is sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or waiver under
this Section 9.02 becomes effective, the Company will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will
not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as
a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this
Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of
Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed
maturity of any Note or alter any of the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.11, 4.10 and 4.15 hereof); 
  

 79 

 (3) reduce the rate of or change the time for payment of interest, including default
interest, on any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or premium or Additional
Interest, if any, or interest on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from
such acceleration); 
 (5) make any Note payable in money other than that stated in the Notes; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive
payments of principal of, or interest or premium or Additional Interest, if any, on, the Notes; 
 (7) waive a redemption
payment with respect to any Note (other than a payment required by Sections 3.11, 4.10 or 4.15 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. 
 Section 9.03 Compliance with Trust Indenture
Act. 
 Every amendment or supplement to this Indenture or the Notes will be set forth in a amended or supplemental indenture that
complies with the TLA as then in effect. 
 Section 9.04 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may
revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder. 
 Section 9.05 Notation on or Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for
all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 
 Section 9.06 Trustee to Sign Amendments, etc. 
 The Trustee will sign any amended or supplemental
indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of 
  

 80 

 the Trustee. The Company may not sign an amended or supplemental indenture until the Board of Directors of the Company
approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04
hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 
 ARTICLE 10 
 SUBORDINATION 
 Section 10.01 Agreement to Subordinate. 
 The Company agrees, and each Holder by accepting a Note
agrees, that the Indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 10, to the prior payment in full of all Senior Debt (whether outstanding on the date hereof or
hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Debt. 
 Section 10.02
Liquidation; Dissolution; Bankruptcy. 
 Upon any distribution to creditors of the Company in a liquidation or dissolution of the
Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, in an assignment for the benefit of creditors or any marshaling of the Company’s assets and liabilities:

 (1) holders of Senior Debt will be entitled to receive payment in full of all Obligations due in respect of such Senior
Debt (including interest after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Debt) before the Holders of Notes will be entitled to receive any payment with respect to the Notes (except that Holders of
Notes may receive and retain Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof); and 
 (2) until all Obligations with respect to Senior Debt (as provided in clause (1) above) are paid in full, any distribution to which Holders would be entitled but for this Article 10 will be made to holders of
Senior Debt (except that Holders of Notes may receive and retain Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof), as their interests may appear. 
 Section 10.03 Default on Designated Senior Debt. 
 (a) The Company may not make any payment or distribution to the Trustee or any Holder in respect of Obligations with respect to the Notes and may not acquire from the Trustee or any Holder any Notes for cash or property (other than
Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof) until all principal and other Obligations with respect to the Senior Debt have been paid in full if: 
 (1) payment default on Designated Senior Debt occurs and is continuing beyond any applicable grace period in the agreement, indenture or
other document governing such Designated Senior Debt; or 
  

 81 

 (2) any other default occurs and is continuing on any series of Designated Senior Debt
that permits holders of that series of Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of such default (a “Payment Blockage Notice”) from the Company of the holders of any Designated Senior Debt.
If the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice will be effective for purposes of this Section 10.03 unless and until (A) at least 360 days have elapsed since the effectiveness of the
immediately prior Payment Blockage Notice and (B) all scheduled payments of principal, premium and Additional Interest, if any, and interest on the Notes that have come due have been paid in full in cash. 
 No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee may be, or may be made, the
basis for a subsequent Payment Blockage Notice unless such default has have been waived for a period of not less than 90 days. 
 (b) The
Company may and will resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of: 
 (1) in the case of a payment default, upon the date upon which such default is cured or waived, or 
 (2) in the case
of a nonpayment default, upon the earlier of the date on which such nonpayment default is cured or waived or 179 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has
been accelerated, 
 if this Article 10 otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition. 
 Section 10.04 Acceleration of Notes. 
 If payment
of the Notes is accelerated because of an Event of Default, the Company will promptly notify holders of Senior Debt of the acceleration. 
 Section 10.05 When Distribution Must Be Paid Over. 
 In the event that the Trustee or any Holder receives any payment of
any Obligations with respect to the Notes (other than Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof) at a time when the Trustee or such Holder, as applicable, has actual
knowledge that such payment is prohibited by Section 10.03 hereof, such payment will be held by the Trustee or such Holder, in trust for the benefit of, and will be paid forthwith over and delivered, upon written request, to, the holders of
Senior Debt as their interests may appear or their Representative under the agreement, indenture or other document (if any) pursuant to which Senior Debt may have been issued, as their respective interests may appear, for application to the payment
of all Obligations with respect to Senior Debt remaining unpaid to the extent necessary to pay such Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior
Debt. 
 With respect to the holders of Senior Debt, the Trustee undertakes to perform only those obligations on the part of the Trustee as
are specifically set forth in this Article 10, and no implied covenants or obligations with respect to the holders of Senior Debt will be read into this Indenture against the Trustee. The Trustee will not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and 
  

 82 

 will not be liable to any such holders if the Trustee pays over or distributes to or on behalf of Holders or the Company
or any other Person money or assets to which any holders of Senior Debt are then entitled by virtue of this Article 10, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. 
 Section 10.06 Notice by Company. 
 The Company
will promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of any Obligations with respect to the Notes to violate this Article 10, but failure to give such notice will not affect the
subordination of the Notes to the Senior Debt as provided in this Article 10. 
 Section 10.07 Subrogation. 
 After all Senior Debt is paid in full and until the Notes are paid in full, Holders of Notes will be subrogated (equally and ratably with all other
Indebtedness pari passu with the Notes) to the rights of holders of Senior Debt to receive distributions applicable to Senior Debt to the extent that distributions otherwise payable to the Holders of Notes have been applied to the payment of
Senior Debt. A distribution made under this Article 10 to holders of Senior Debt that otherwise would have been made to Holders of Notes is not, as between the Company and Holders, a payment by the Company on the Notes. 
 Section 10.08 Relative Rights. 
 This Article 10
defines the relative rights of Holders of Notes and holders of Senior Debt. Nothing in this Indenture will: 
 (1) impair, as
between the Company and Holders of Notes, the obligation of the Company, which is absolute and unconditional, to pay principal of, premium and interest and Additional Interest, if any, on, the Notes in accordance with their terms; 
 (2) affect the relative rights of Holders of Notes and creditors of the Company other than their rights in relation to holders of Senior
Debt; or 
 (3) prevent the Trustee or any Holder of Notes from exercising its available remedies upon a Default or Event of
Default, subject to the rights of holders and owners of Senior Debt to receive distributions and payments otherwise payable to Holders of Notes. 
 If the Company fails because of this Article 10 to pay principal of, premium or interest or Additional Interest, if any, on, a Note on the due date, the failure is still a Default or Event of Default. 
 Section 10.09 Subordination May Not Be Impaired by Company. 
 No right of any holder of Senior Debt to enforce the subordination of the Indebtedness evidenced by the Notes may be impaired by any act or failure to act by the Company or any Holder or by the failure of the Company
or any Holder to comply with this Indenture. 
 Section 10.10 Distribution or Notice to Representative. 
 Whenever a distribution is to be made or a notice given to holders of Senior Debt, the distribution may be made and the notice given to their
Representative. 
  

 83 

 Upon any payment or distribution of assets of the Company referred to in this Article 10, the Trustee and
the Holders of Notes will be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders of Notes for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Debt and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 10. 
 Section 10.11 Rights of Trustee and Paying
Agent. 
 Notwithstanding the provisions of this Article 10 or any other provision of this Indenture, the Trustee will not be charged with
knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes, unless the Trustee has received at its Corporate
Trust Office at least five Business Days prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Notes to violate this Article 10. Only the Company or a Representative may give
the notice. Nothing in this Article 10 will impair the claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof. 
 The Trustee in its individual or any other capacity may hold Senior Debt with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. 
 Section 10.12 Authorization to Effect Subordination. 
 Each Holder of Notes, by the Holder’s
acceptance thereof, authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 10, and appoints the Trustee to act as such
Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 6.09 hereof at least 30 days before the expiration
of the time to file such claim, the Representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Notes. 
 Section 10.13 Amendments. 
 The provisions of this Article 10 may not be amended or modified without the written consent
of the holders of all Senior Debt. In addition, any amendment to, or waiver of, the provisions of this Article 10 that adversely affects the rights of the Holders of the Notes will require the consent of the Holders of at least 75% in aggregate
principal amount of Notes then outstanding. 
 ARTICLE 11 
 NOTE GUARANTEES 
 Section 11.01 Guarantee. 
 (a) Subject to this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated
and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: 
 (1) the principal of, premium and Additional Interest, if any, and interest on, the Notes will be promptly paid in full when due, whether
at maturity, by acceleration, redemption or 
  

 84 

 otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all
other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of
payment and not a guarantee of collection. 
 (b) The Guarantors hereby agree that their obligations hereunder are unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery
of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be
discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
 (c) If any Holder or the Trustee
is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or
such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 
 (d) Each Guarantor
agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the
Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such
obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the
exercise of such right does not impair the rights of the Holders under the Note Guarantee. 
 Section 11.02 Subordination of Note Guarantee.

 The Obligations of each Guarantor under its Note Guarantee pursuant to this Article 11 will be junior and subordinated to the Senior Debt
of such Guarantor on the same basis as the Notes are junior and subordinated to Senior Debt of the Company. For the purposes of the foregoing sentence, the Trustee and the Holders will have the right to receive and/or retain payments by any of the
Guarantors only at such times as they may receive and/or retain payments in respect of the Notes pursuant to this Indenture, including Article 10 hereof. 
  

 85 

 Section 11.03 Limitation on Guarantor Liability. 
 Each Guarantor, and by its acceptance of 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 other applicable 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 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 11, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. 
 Section 11.04 Execution and Delivery of Note Guarantee. 
 To evidence its Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such
Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers. 
 Each Guarantor hereby agrees that its Note Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

 If an Officer whose signature is on this Indenture or on the Note Guarantee no longer holds that office at the time the Trustee
authenticates the Note on which a 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 Note Guarantee set forth in this Indenture on behalf of the Guarantors. 
 In the event that the Company or any of its Restricted Subsidiaries creates or acquires any Restricted Subsidiary after the date of this Indenture, if required by Section 4.19 hereof, the Company will cause such
Restricted Subsidiary to comply with the provisions of Section 4.19 hereof and this Article 11, to the extent applicable. 
 Section 11.05
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 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 
 (2) either: 
 (A) subject to Section 11.06 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger 
  

 86 

 unconditionally assumes all the obligations of that Guarantor under this Indenture, its Note Guarantee
and the Registration Rights Agreement on the terms set forth herein or therein, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee; 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, 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 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 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 Note Guarantees had been issued at the date of the
execution hereof. 
 Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (b) above, nothing contained
in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as
an entirety to the Company or another Guarantor. 
 Section 11.06 Releases. 
 (a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or
otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the Company, then such
Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or
substantially all of the assets of such Guarantor) will be released and relieved of any obligations under its Note Guarantee; provided that 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 (subject to the conditions and limitations set forth in Section 4.10). Upon delivery by the Company to the Trustee of an Officers’ Certificate and an
Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture, including without limitation Section 4.10 hereof, the Trustee will execute any documents
reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee. 
 (b) Upon designation
of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be released and relieved of any obligations under its Note Guarantee. 
 (c) Upon Legal Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 12 hereof, each
Guarantor will be released and relieved of any obligations under its Note Guarantee. 
  

 87 

 Any Guarantor not released from its obligations under its Note Guarantee as provided in this
Section 11.05 will remain liable for the full amount of principal of and interest and premium and Additional Interest, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11.

 ARTICLE 12 
 SATISFACTION AND
DISCHARGE 
 Section 12.01 Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 
 (1) either: 
 (A) all Notes that have been authenticated, except lost, stolen or destroyed
Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 
 (B) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a
notice of redemption or otherwise or will become due and payable at their maturity within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit
of the Holders of the Notes, 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, without consideration of any reinvestment of
interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium and Additional Interest, if any, and accrued interest to the date of maturity or redemption; 
 (2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the
Company or any Guarantor is bound; 
 (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it
under this Indenture; and 
 (4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to
apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
 In addition, the
Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause
(1) of this Section 12.01, the provisions of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms,
survive the satisfaction and discharge of this Indenture. 
  

 88 

 Section 12.02 Application of Trust Money. 
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust
and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium and Additional Interest, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by
law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 12.01 hereof by
reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Company has made any payment of principal of, premium or Additional Interest, if any, or
interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

Refinancing Indebtedness is incurred to refinance Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar denominated restriction to be exceeded if calculated on the date of such refinancing, such
U.S. dollar denominated restriction will be deemed not have been exceeded so long as the principal amount of such Permitted Refinancing Indebtedness does not exceed the principal amount of such Debt being refinanced. Notwithstanding any other
provision in this Indenture, no restriction or amount will be exceeded solely as a result of fluctuations in the exchange rate of currencies.

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

 (1) INTEREST. Angiotech Pharmaceuticals, Inc., a corporation organized under the Laws of British
Columbia (the “Company”), promises to pay interest on the principal amount of this Note at 7.75 % per annum from March 23, 2006 until maturity and shall pay the Additional Interest, if any, payable pursuant to
Section 6 of the Registration Rights Agreement referred to below. The Company will pay interest and Additional Interest, if any, semi-annually in arrears on April 1 and October 1 of each year, or if any such day is not a Business Day,
on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance;
provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such
next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 1, 2006. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the rate then in effect to the extent lawful; it will pay interest (including post- petition interest in any proceeding under any Bankruptcy
Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360- day year
of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Company will pay
interest on the Notes (except defaulted interest) and Additional Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even
if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and
Additional Interest, if any, and interest at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest and Additional 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 and interest, premium and
Additional Interest, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company 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.

Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are unsecured obligations of the Company limited to S250 million in aggregate principal amount, plus amounts, if any, issued to pay Additional Interest on outstanding Notes as set forth in
Paragraph 2 hereof. 
 (5) OPTIONAL REDEMPTION. 
 (a) Except as set forth in subparagraph (b) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to April 1,
2009. On or after April 1, 2009, the Company will have the option to redeem all or a part of the Notes upon not less than 30 nor more than 60 days notice, at the redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed to the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 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:

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue
on the Notes or portions thereof called for redemption on the applicable redemption date. 
 (b) Notwithstanding the provisions of
subparagraph (a) of this Paragraph 5, at any time prior to April 1, 2009, the Company may redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture with the net cash proceeds of one or more Public Equity
Offerings at a redemption price equal to 107.75% of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any to the redemption date; provided that at least 65% in aggregate principal amount at
maturity of the Notes originally issued under the Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption and that such redemption occurs within 45 days of the date
of the closing of such Public Equity Offering. 
 (c) The Company may also choose to redeem the Notes at any time prior to April 1,
2009, in whole or in part, on not less than 30 nor more than 60 days’ notice, by paying a redemption price equal to the sum of: 
 (1) 100% of the principal amount of the Notes to be redeemed, plus 
 (2) the Applicable Premium (as defined in the

Notes. 
 (7) REPURCHASE AT THE OPTION OF
HOLDER. 
 (A) If there is a Change of Control, the Company will be required to make an offer (a
“Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”).
Within 20 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 
 (B) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within 20 days of each date on which the
aggregate amount of Excess Proceeds exceeds $15.0 million, the Company will commence an offer to all Holders of Notes and all Holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in
the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) pursuant to Section 3.11 of the Indenture to purchase the maximum principal amount of Notes and such other
pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the
date of purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company (or such Restricted Subsidiary) may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive an Asset
Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes. 
 (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection
with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed.

 (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $2,000 and integral multiples of $ 1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a
Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or

 (10) PERSONS DEEMED OWNERS. The
registered Holder of a Note may be treated as its owner for all purposes. 
 (11) AMENDMENT,

aggregate principal amount of the then outstanding Notes, including Additional Notes, if any, voting as a single class, and subject to certain exceptions, any existing Default or Event or Default or compliance with any provision of the 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 Additional Notes, if any voting as a single class. Without the consent of any Holder
of a Note, the Indenture or the Notes or the Note Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the
assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights under the Indenture of any such Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, to conform the text of the
Indenture or the Notes to any provision of the “Description of Notes” section of the Company’s Offering Circular dated March 16, 2006, relating to the initial offering of the Notes, to the extent that such provision in that
“Description of Notes” was intended to be a verbatim recitation of a provision of the Indenture, the Note Guarantees or the Notes, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the
Indenture; or to allow any Guarantor to execute a supplemental indenture to the Indenture and/or a Note Guarantee with respect to the Notes. 
 (12) DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest on, or Additional Interest, if any, with
respect to, the Notes, whether or not prohibited by the subordination provisions of this Indenture; (ii) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes, whether
or not prohibited by the subordination provisions of this Indenture; (iii) failure by the Company or any of its Restricted Subsidiaries to comply with the provisions of Sections 4.07, 4.09, 4.10, 4.15 or 5.01 hereof; (iv) failure by the Company
or any of its Restricted Subsidiaries for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other
agreements in this Indenture other than those listed in clause (1), clause (2), or clause (3) of this Section 6.01; (v) default under any mortgage, indenture or instrument under which there may be issued or by which there may be
secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now
exists, or is created after the date of this Indenture, if that default: (a) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such
Indebtedness on the date of such default (a “Payment Default”); or (b) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; (vi) failure by the Company or any of its
Restricted Subsidiaries to pay final judgments entered by a court or 
  

 A1-5 

 courts of competent jurisdiction aggregating in excess of $10.0 million, which judgments are not paid,
discharged or stayed for a period of 60 days; (vii) certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the
Company that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law; or (viii) except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be
unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee. If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising
from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default
or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium or Additional Interest, if any,) if it determines that withholding notice is in their interest. The Holders of a majority in
aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest or premium or Additional Interest, if any, on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance
with the Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
 (13) SUBORDINATION. Payment of principal, interest and premium and Additional Interest, if any, on the Notes is
subordinated to the prior payment of Senior Debt on the terms provided in the Indenture. 
 (14) TRUSTEE
DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal
with the Company or its Affiliates, as if it were not the Trustee. 
 (15) NO RECOURSE
AGAINST OTHERS. A director, officer, employee, incorporator or stockholder of the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or the Guarantors under the
Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes. 
 (16) AUTHENTICATION. This Note will not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent. 
 (17) ABBREVIATIONS.
Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
  

 A1-6 

 (18) ADDITIONAL RIGHTS OF
HOLDERS OF RESTRICTED GLOBAL NOTES AND RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to
Holders of Notes under the Indenture, Holders of Restricted Global Notes and Restricted Definitive Notes will have all the rights set forth in the Registration Rights Agreement dated as of March 23, 2006, among the Company, the Guarantors and
the other parties named on the signature pages thereof or, in the case of Additional Notes, Holders of Restricted Global Notes and Restricted Definitive Notes will have the rights set forth in one or more registration rights agreements, if any,
among the Company, the Guarantors and the other parties thereto, relating to rights given by the Company and the Guarantors to the purchasers of any Additional Notes (collectively, the “Registration Rights Agreement”). 

(19) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of
such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 
 (20) GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE
INDENTURE, THIS NOTE 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. 
 (21) INTEREST ACT (CANADA) Each interest rate which is calculated under the Notes on any basis other than the actual number of days
in a calendar year (the “deemed interest period”) is solely for the purposes of the Interest Act (Canada), equivalent to a yearly rate calculated by dividing such interest rate by the number of days in the deemed interest period, then
multiplying such result by the actual number of days in the calendar year. 
 The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture and/or the Registration Rights Agreement. Requests may be made to:

 Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

Inc., a corporation organized under the Laws of British Columbia (the “Company”), promises to pay interest on the principal amount of this Note at 7.75% per annum from March 23, 2006 until maturity’ and shall pay the
Additional Interest, if any, payable pursuant to Section 6 of the Registration Rights Agreement referred to below. The Company will pay interest and Additional Interest, if any, semi-annually in arrears on April 1 and October 1 of
each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 1, 2006. The Company will pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the rate then in effect to the extent lawful; it will pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent
lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 (2) METHOD
OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) and Additional Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the March 15 or
September 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. The Notes will be payable as to principal, premium and Additional Interest, if any, and interest at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the
Company, payment of interest 
  

 A2-3

in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, premium and Additional Interest, if any, on, all Global Notes and all other Notes
the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and
private debts. 
 (3) PAYING AGENT AND REGISTRAR.
Initially, Wells Fargo Bank, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any
such capacity. 
 (4) INDENTURE. The Company issued the Notes under an Indenture dated as of
March 23, 2006 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA. The Notes are
subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall
govern and be controlling. The Notes are unsecured obligations of the Company limited to $250 million in aggregate principal amount, plus amounts, if any, issued to pay Additional Interest on outstanding Notes as set forth in Paragraph 2 hereof.

 (5) OPTIONAL REDEMPTION. 
 (a) Except as set forth in subparagraph (b) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to April 1,
2009. On or after April 1, 2009, the Company will have the option to redeem all or a part of the Notes upon not less than 30 nor more than 60 days notice, at the redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed to the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 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:

	 2011
	  	101.938	%
	 2012 and thereafter
	  	100.000	%

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue
on the Notes or portions thereof called for redemption on the applicable redemption date. 
 (b) Notwithstanding the provisions of
subparagraph (a) of this Paragraph 5, at any time prior to April 1, 2009, the Company may redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture with the net cash proceeds of one or more Public Equity
Offerings at a redemption price equal to 107.75 % of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any to the redemption date; provided that at least 65% in aggregate principal
amount at maturity of the Notes originally issued under the Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption and that such redemption occurs within 45 days
of the date of the closing of such Public Equity Offering. 
  

 A2-4 

 (c) The Company may also choose to redeem the Notes at any time prior to April 1, 2009, in whole or
in part, on not less than 30 nor more than 60 days’ notice, by paying a redemption price equal to the sum of: 
  

	 	(1)	100% of the principal amount of the Notes to be redeemed, plus 

  

	 	(2)	the Applicable Premium (as defined in the indenture),

interest thereon, if any to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). 
 (6) MANDATORY REDEMPTION 
 The Company is not be required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 (7) REPURCHASE AT THE OPTION OF HOLDER.

 (A) If there is a Change of Control, the Company will be required to make an offer (a “Change of Control
Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 20 days following any
Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 
 (B) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within 20 days of each date on which the
aggregate amount of Excess Proceeds exceeds $15.0 million, the Company will commence an offer to all Holders of Notes and all Holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in
the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) pursuant to Section 3.11 of the Indenture to purchase the maximum principal amount of Notes and such other
pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the
date of purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company (or such Restricted Subsidiary) may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive an Asset
Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes. 
 (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection
with a defeasance of the 
  

 A2-5 

 Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be
redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. 
 (9)
DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes
may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required
by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not
exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its
owner for all purposes. 
 (11) AMENDMENT, SUPPLEMENT AND
WAIVER. Subject to certain exceptions, the Indenture or the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding
Notes, including Additional Notes, if any, voting as a single class, and subject to certain exceptions, any existing Default or Event or Default or compliance with any provision of the 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 Additional Notes, if any voting as a single class. Without the consent of any Holder of a Note, the Indenture or the Notes or the Note
Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or a Guarantor’s
obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights
under the Indenture of any such Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, to conform the text of the Indenture or the Notes to any provision of the
“Description of Notes” section of the Company’s Offering Circular dated March 16, 2006, relating to the initial offering of the Notes, to the extent that such provision in that “Description of Notes” was intended to be
a verbatim recitation of a provision of the Indenture, the Note Guarantees or the Notes, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture; or to allow any Guarantor to execute a
supplemental indenture to the Indenture and/or a Note Guarantee with respect to the Notes. 
 (12) DEFAULTS
AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest on, or Additional Interest, if any, with respect to, the Notes, whether or not prohibited by the
subordination provisions of this Indenture; (ii) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes, whether or not prohibited by the subordination provisions of
this Indenture; (iii) failure by the Company or any of its Restricted Subsidiaries to comply with the provisions of Sections 4.07, 4.09, 4.10, 4.15 or 5.01 hereof; (iv) failure by the Company or any of its Restricted Subsidiaries for 60
days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply 
  

 A2-6 

 with any of the other agreements in this Indenture other than those listed in clause (1), clause (2), or
clause (3) of this Section 6.01; (v) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, if that default: (a) is
caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or
(b) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; (vi) failure by the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction
aggregating in excess of $10.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; (vii) certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted Subsidiaries that is a
Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law; or (viii) except as permitted by this Indenture,
any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations
under its Note Guarantee. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium or Additional Interest, if any,) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing
Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium or Additional Interest, if any, on, or the principal of, the Notes. The Company is required to
deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of
Default. 
 (13) SUBORDINATION. Payment of principal, interest and premium and Additional Interest, if
any, on the Notes is subordinated to the prior payment of Senior Debt on the terms provided in the Indenture. 
 (14)
TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates,
and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 
  

 A2-7 

 (15) NO RECOURSE AGAINST
OTHERS. A director, officer, employee, incorporator or stockholder of the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or the Guarantors under the Notes, the Note
Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration
for the issuance of the Notes. 
 (16) AUTHENTICATION. This Note will not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent. 
 (17) ABBREVIATIONS. Customary
abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian),
and U/G/M/A (= Uniform Gifts to Minors Act). 
 (18) ADDITIONAL RIGHTS OF
HOLDERS OF RESTRICTED GLOBAL NOTES AND RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to
Holders of Notes under the Indenture, Holders of Restricted Global Notes and Restricted Definitive Notes will have all the rights set forth in the Registration Rights Agreement dated as of March 23, 2006, among the Company, the Guarantors and
the other parties named on the signature pages thereof or, in the case of Additional Notes, Holders of Restricted Global Notes and Restricted Definitive Notes will have the rights set forth in one or more registration rights agreements, if any,
among the Company, the Guarantors and the other parties thereto, relating to rights given by the Company and the Guarantors to the purchasers of any Additional Notes (collectively, the “Registration Rights Agreement”). 

(19) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures, the Company has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed
on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 
 (20) GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE 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. 
 (21) INTEREST ACT
(CANADA) Each interest rate which is calculated under the Notes on any basis other than the actual number of days in a calendar year (the “deemed interest period”) is solely for the purposes of the Interest Act (Canada), equivalent to
a yearly rate calculated by dividing such interest rate by the number of days in the deemed interest period, then multiplying such result by the actual number of days in the calendar year.

 SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of
                            , 200    , among
                             (the “Guaranteeing Subsidiary”), a subsidiary of
                             (or its permitted successor), a [Delaware] corporation (the
“Company”), the Company, the other Guarantors (as defined in the Indenture referred to herein) and Wells Fargo Bank, N.A., as trustee under the Indenture referred to below (the “Trustee”). 
 W I T N E S S E T H 
 WHEREAS, the Company
has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of March 23, 2006 providing for the issuance of 7.75% Senior Subordinated Notes due 2014 (the “Notes”); 

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

 NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby
acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 
 2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and
subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 11 thereof. 
 4.

any obligations of the Company or any Guaranteeing Subsidiary under the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws
and it is the view of the SEC that such a waiver is against public policy.

YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE 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. 
 6. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all
of them together represent the same agreement.
