The aggregate principal amount of Units (and the corresponding amount of Notes) outstanding at any time may not exceed the aggregate principal amount of Units (and the corresponding amount of Notes) authorized for issuance by the Issuers pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

The Trustee may appoint an authenticating agent acceptable to the Issuers to authenticate Units (and the Notes comprising such Units). An authenticating agent may authenticate Units (and the Notes comprising such Units) whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Issuers.

Section 2.03 Registrar and Paying Agent.

The Issuers will maintain an office or agency where Units may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register (the “Register”) of the Units and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents.

The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuers or any of their Subsidiaries may act as Paying Agent or Registrar.

The Issuers initially appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Units.

The Issuers initially appoint the Trustee to act as the Registrar and Paying Agent in connection with the Units, until such time as the Trustee has resigned or a successor has been appointed pursuant to Section 7.07 hereof, and to act as Custodian with respect to the Global Units.

Section 2.04 Paying Agent to Hold Money in Trust.

On or prior to 10:00 a.m. New York City time on each due date of the principal and interest on any Unit, the Issuers shall deposit with the Paying Agent a sum sufficient to pay such principal and interest on any Unit as it becomes due. The Issuers shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest, if any, on the Units, and shall notify the Trustee of any default by the Issuers in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than an Issuer or a Subsidiary) shall have no further liability for the money. If an Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to an Issuer, the Trustee shall serve as Paying Agent for the Units.

Section 2.05 Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee or cause the Registrar to furnish to the Trustee, at least five (5) Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Units; provided that as long as the Trustee is the Registrar, no such list need be furnished.

Section 2.06 Transfer and Exchange.

(2) No service charge will be made to a Holder of a beneficial interest in a Global Unit or to a Holder of a Definitive Unit for any registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.07, 3.08, 4.10, 4.15 and 9.04 hereof).

(3) All Global Units and Definitive Units issued upon any registration of transfer or exchange of Global Units or Definitive Units will be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Units or Definitive Units surrendered upon such registration of transfer or exchange.

(4) Neither the Registrar nor the Issuers will be required:

(A) to issue, to register the transfer of or to exchange any Units during a period beginning at the opening of business fifteen (15) days before the day of any selection of Units for redemption under Section 3.03 hereof and ending at the close of business on the day of selection;

(B) to register the transfer of or to exchange any Unit selected for redemption in whole or in part, except the unredeemed portion of any Unit being redeemed in part; or

(C) to register the transfer of or to exchange a Unit between a record date and the next succeeding interest payment date.

(5) Prior to due presentment for the registration of a transfer of any Unit, the Trustee, any Agent and the Issuers may deem and treat the Person in whose name any Unit is registered as the absolute owner of such Unit for the purpose of receiving payment of principal of and (subject to the record date provisions of the Notes) interest on such Units and for all other purposes, and none of the Trustee, any Agent or the Issuers shall be affected by notice to the contrary.

(6) The Trustee will authenticate Global Units and Definitive Units in accordance with the provisions of Section 2.02 hereof.

(7) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

Neither the Trustee nor the Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants, members or beneficial owners in any Global Unit) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

The Trustee shall retain copies of all letters, notices and other written communications received pursuant to this Section 2.06 (including all Units received for transfer pursuant to this Section 2.06). The Issuers shall have the right to require the Trustee to deliver to the Issuers, at their expense, copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Trustee.

In connection with any transfer of any Unit, the Trustee and the Issuers shall be entitled to receive, shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the certificates, opinions and other information referred to herein (or in the forms provided herein, attached hereto or to the Unit, or otherwise) received from any Holder and any transferee of any Unit regarding the validity, legality and due authorization of any such transfer, the eligibility of the transferee to receive such Unit and any other facts and circumstances related to such transfer.

Section 2.07 Replacement Units.

If any mutilated Units are surrendered to the Trustee or the Issuers or if the Holder of a Unit claims that the Unit has been lost, destroyed or wrongfully taken, the applicable Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Unit if the Holder satisfies any reasonable requirements of the Trustee and the Issuers. If required by the Trustee or the Issuers, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Unit is replaced. The Issuers and the Trustee may charge the Holders for each of its expenses in replacing a Unit.

In case any such mutilated, destroyed, lost, or stolen Unit has become or is about to become due and payable, the applicable Issuer in its sole discretion may, instead of issuing a new Unit, pay such Unit.

Upon the issuance of any new Unit under this Section 2.07, the applicable Issuer may require the payment of a sum sufficient to cover any tax, assessment, fee or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Unit issued pursuant to this Section 2.07 in exchange for any mutilated Unit or in lieu of any destroyed, lost, or stolen Unit will constitute an original additional contractual obligation of the applicable Issuer, whether or not the mutilated, destroyed, lost, or stolen Unit shall be at any time enforceable by anyone, and will be entitled to all the benefits of this Indenture equally and proportionately with any and all other Units duly issued hereunder.

The provisions of this Section 2.07 are exclusive and will preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost, or stolen Units.

Section 2.08 Outstanding Units.

The Units (and the Notes comprising such Units) outstanding at any time are all the Units and 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 Unit 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 Unit does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Unit; however, Units held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.01(a) hereof.

If a Unit is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee and the Issuers receive proof satisfactory to them that the replaced Unit is held by a protected purchaser. A mutilated Unit ceases to be outstanding upon surrender of such Unit and replacement thereof pursuant to Section 2.07 hereof. If the principal amount of any Unit (or the corresponding amount of any Note comprising such Unit) is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than an Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Units payable on that date, then on and after that date such Units will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Units.

In determining whether the Holders of the required principal amount of Units have concurred in any direction, waiver or consent, Units owned by the Issuers or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with an Issuer or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Units that a Responsible Officer of the Trustee actually knows are so owned will be so disregarded.

Section 2.10 Temporary Units.

Until certificates representing Units are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Units (and Notes comprising such Units). Temporary Units will be substantially in the form of certificated Units but may have variations that the Issuers consider appropriate for temporary Units and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will authenticate definitive Units (and Notes comprising such Units) in exchange for temporary Notes and Units, respectively.

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

Section 2.11 Cancellation.

The Issuers at any time may deliver Units to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Units surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Units surrendered for registration of transfer, exchange, payment, replacement or cancellation. The Trustee shall dispose of all cancelled Units in accordance with its customary procedures and shall deliver a certificate of disposition to the applicable Issuer upon written request therefor. Subject to Section 2.07 hereof, the Issuers may not issue new Units to replace Units that have been paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

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

Section 2.13 Issuance of Additional Units.

The Issuers shall be entitled, from time to time, subject to its compliance with Section 4.09 and Section 4.12 hereof, without consent of the Holders, to issue Additional Units under this Indenture with identical terms as the Notes other than with respect to (i) the date of issuance, (ii) the issue price, (iii) the amount of interest payable on the first interest payment date, initial interest accrual date and initial interest payment date and (iv) any adjustments in order to conform to and ensure compliance with the Securities Act (or other applicable securities laws). The Initial Units and any Notes issued as Additional Units shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Units, the Issuers shall set forth in an Officers’ Certificate pursuant to a resolution of the Board of Directors of each of the Issuers, copies of which shall be delivered to the Trustee, the following information:

(1) The aggregate principal amount of Units and the aggregate principal amount of Notes constituting Additional Units to be authenticated and delivered pursuant to this Indenture; and

(2) the issue price, the issue date and the CUSIP number of such Additional Units.

Section 3.02 Notices to Trustee.

If the Issuers jointly elect to redeem Notes as Units pursuant to Section 3.01 hereof, they shall notify the Trustee in writing of the redemption date, the principal amount of Notes to be redeemed, the redemption price and the paragraph of the Notes pursuant to which the redemption will occur. The Issuers shall give such notice to the Trustee at least five (5) days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to Section 3.01 hereof unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’ Certificate from the Issuers to the effect that such redemption will comply with the provisions herein. Such Officers’ Certificate shall also state that all conditions precedent, if any, provided for herein to such redemption have been complied with.

Section 3.03 Selection of Notes as Units to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed or repurchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase as Units on a pro rata basis (provided that, in the case of Notes issued in global form pursuant to Article 2 hereof, the Depositary may select interests in the Notes for redemption or purchase pursuant to its applicable procedures) unless otherwise required by law or applicable stock exchange or depositary requirements. The Trustee shall make the selection from outstanding Notes not previously called for redemption or purchase. Units consisting of Notes having an aggregate principal amount in excess of $2,000 may be redeemed or purchased in part but only in whole multiples of $1,000, except that if all of the Units or Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes or Units held by such Holder shall be redeemed or purchased. In connection with any pro rata selection of Notes for purchase or redemption, the Trustee may make such adjustments downward or upward (by not more than $1,000) so that Notes shall only be redeemed or purchased in authorized denominations.

If any Note as a Unit is to be redeemed or purchased in part only, the notice relating to such Note as a Unit shall state the portion of the principal amount thereof to be redeemed or purchased. A new Unit (and corresponding Notes) in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Units (and corresponding Notes). Provisions of this Indenture that apply to Notes as Units called for redemption or purchase also apply to portions of Notes as Units called for redemption or purchase. The Trustee shall notify the Issuers promptly of the Notes as Units or portions of Notes as Units to be redeemed or purchased.

Section 3.04 Notice of Redemption.

At least thirty (30) days, or at least ten (10) days in the case of any redemption pursuant to Section 3.01(c) hereof, but not more than sixty (60) days before a redemption date, the Issuers will mail or cause to be mailed, by first class mail or, in the case of Notes held as Units in book-entry form, by electronic transmission in accordance with the customary practices of the Depositary, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than sixty (60) days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 11 hereof.

The notice will identify the Notes as Units to be redeemed and shall state:

(1) the redemption date;

(2) the redemption price (or if not then ascertainable, the manner of calculation thereof);

(3) if any Note as a Unit is being redeemed in part, the portion of the principal amount of such Note as a Unit to be redeemed and that, after the redemption date upon surrender of such Unit (and corresponding Notes), a new Unit or Units (and corresponding Notes) in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Unit (and corresponding Note);

(4) the name and address of the Paying Agent;

(5) that Notes as Units 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 as Units called for redemption ceases to accrue on and after the redemption date;

(7) the paragraphs of the Notes and/or Section of this Indenture pursuant to which the Notes as Units called for redemption are being redeemed;

(8) the CUSIP number, if any, printed on the Units being redeemed; and

(9) that no representation is made as to the correctness or accuracy of the CUSIP numbers, if any, listed in such notice or printed on the Units being redeemed.

At the Issuers’ request, the Trustee shall give the notice of redemption in the Issuers’ names and at their expense; provided, however, that such request by the Issuers to the Trustee is received by the Trustee at least five (5) Business Days prior to the date the Trustee is requested to give notice to the Holders whose Notes as Units are to be redeemed. In such event, the Issuers shall provide the Trustee with the information required by this Section 3.04.

Section 3.05 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.04 hereof, Notes as Units called for redemption become irrevocably due and payable on the redemption date at the redemption price stated in the notice. A notice of redemption may not be conditional. Upon surrender to the Paying Agent, such Notes shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date. Such notice if mailed in the manner herein provided shall be conclusively presumed to have been given, whether or not the Holder receives such notice. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

Section 3.06 Deposit of Redemption or Purchase Price.

Prior to 10:00 a.m. (New York City time) on the redemption date or Purchase Date, the Issuers shall deposit with the Trustee or Paying Agent (or, if the Issuers or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption or purchase price of and accrued interest (if any) on all Units (and corresponding Notes) or portions thereof to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of and accrued interest, if any, on all Units (and corresponding Notes) to be redeemed or purchased.

If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or Purchase Date, interest will cease to accrue on the Units (and corresponding Notes) or the portions of thereof called for redemption or purchase. If a Unit (and corresponding Notes) are 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 Unit was registered at the close of business on such record date. If any Unit (and corresponding Notes) called for redemption or purchase are not so paid upon surrender for redemption or purchase because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the corresponding Notes and in Section 4.01 hereof.

Section 3.07 Notes Redeemed or Purchased in Part.

Upon surrender of a Unit (and corresponding Notes) that are redeemed or purchased in part (with, if the Issuers or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuers and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), the Issuers shall execute, and the Trustee shall authenticate and deliver to the Holder of such Units (and corresponding Notes) without service charge, a new Unit or Units (and corresponding Notes) of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Unit (and corresponding Notes) so surrendered, except that if a Global Unit is so surrendered, the Issuers shall execute, and the Trustee shall authenticate and deliver to the Depository for such Global Unit, without service charge, a new Global Unit in denomination equal to and in exchange for the unredeemed portion of the principal of the Global Unit so surrendered.

Section 3.08 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Issuers are required to commence a joint offer to all Holders to purchase Notes as Units (an “Asset Sale Offer”), they will follow the procedures specified below.

The Asset Sale Offer shall be made to all Holders. The Asset Sale Offer will remain open for a period of at least twenty (20) Business Days following its commencement and not more than thirty (30) Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five (5) Business Days after the termination of the Offer Period (the “Purchase Date”), the Issuers will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes as Units or, if less than the Offer Amount has been tendered, all Notes as Units and other Indebtedness tendered in response to the Asset Sale Offer.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a Unit is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes as Units pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Issuers will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 3.08 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase price and the Purchase Date;

(3) that any Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Issuers default in making such payment, any Unit (and corresponding Notes) 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 as a Unit purchased pursuant to an Asset Sale Offer may elect to have Notes as Units purchased in denominations of $2,000 or an integral multiple of $1,000 in excess thereof;

(6) that Holders electing to have Notes as a Unit purchased pursuant to any Asset Sale Offer will be required to surrender the Notes as Units, with the form entitled “Option of Holder to Elect Purchase” attached to the Units completed, or transfer a beneficial interest in the Notes as Units by book-entry transfer, to the Issuers, a depositary, if appointed by the Issuers, or a Paying Agent at the address specified in the notice at least three (3) days before the Purchase Date;

(7) that Holders will be entitled to withdraw their election if the Issuers, the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Unit (and corresponding Notes) the Holder delivered for purchase , the serial number of such Unit if held in definitive form, and a statement that such Holder is withdrawing his election to have such Notes as Units purchased;

(8) that, if the aggregate principal amount of Units (and corresponding Notes) surrendered by holders thereof exceeds the Offer Amount, the Company will select the Unit (and corresponding Notes) to be purchased on a pro rata basis based on the principal amount of Units (and corresponding Notes); and

(9) that Holders whose Units (and corresponding Notes) were purchased only in part will be issued new Units (and corresponding Notes) equal in principal amount to the unpurchased portion of the Units (and corresponding Notes) surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes as Units or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes as Units tendered, and will deliver or cause to be delivered to the Trustee the Units (and corresponding Notes) properly accepted together with an Officers’ Certificate of the applicable Issuer stating that such Units (and corresponding Notes) or portions thereof were accepted for payment by the Issuers in accordance with the terms of this Section 3.08. The Issuers, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five (5) Business Days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes as Units tendered by such Holder and accepted by the Issuers for purchase. Upon surrender of a Unit (and corresponding Notes) that are purchased in part, the Issuers shall execute, and the Trustee shall authenticate and deliver to the Holder of such Unit (and corresponding Notes) without service charge, a new Unit or Units (and corresponding Notes) of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unpurchased portion of the principal of the Notes as Units so surrendered, except that if a Global Unit is so surrendered, the Issuers shall execute, and the Trustee shall authenticate and deliver to the Depository for such Global Unit, without service charge, a new Global Unit in denomination equal to and in exchange for the unpurchased portion of the principal of the Global Unit so surrendered. Any Units (and corresponding Notes) not so accepted shall be promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers will announce the results of the Asset Sale Offer to the Holders on the Purchase Date.

Other than as specifically provided in this Section 3.08, any purchase pursuant to this Section 3.08 shall be made pursuant to the provisions of Sections 3.03, 3.06 and 3.07 hereof.

The Issuers shall pay or cause to be paid the principal of, or premium or interest, if any, on the Notes on the dates and in the manner provided in the Notes.

If at any time the Issuers fail to maintain any such required office or agency or fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Issuers may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Issuers of their obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Issuers will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Notwithstanding the foregoing, such reports (A) will not be required to comply with Section 302 or Section 404 of the Xxxxxxxx-Xxxxx Act of 2002, or related Items 307 and 308 of Regulation S-K promulgated by the SEC, or Item 10(e) of Regulation S-K (with respect to any non-GAAP financial measures contained therein) and (B) will not be required to contain the separate financial information for Guarantors or Subsidiaries whose securities are pledged to secure the Notes contemplated by Rule 3-10 or Rule 3-16 of Regulation S-X promulgated by the SEC; provided, however, the Company shall not be required to comply with Rule 3-05 of Regulation S-X if the Company determines in its good faith judgment that such event giving rise to the application of Rule 3-05 is not material to the Holders or the business, assets, operations or financial positions of the Company and its Restricted Subsidiaries, taken as a whole. The availability of any of the foregoing reports (or equivalent information in a registration statement on Form S-1 or other form or report) on the SEC’s XXXXX filing system (or other successor electronic filing system) shall be deemed to satisfy the Company’s delivery obligations with respect thereto.

(b) At any time that any of the Company’s Subsidiaries are Unrestricted Subsidiaries, then the quarterly and annual reports required by paragraph (a) of this Section 4.03 will include (or the Company will separately furnish to the Trustee) a reasonably detailed presentation of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

(c) So long as any Notes are outstanding, (1) within ten (10) Business Days after furnishing to the Trustee annual reports required by paragraph (a)(1) of this Section 4.03 (or within ten (10) Business Days after such reports becoming available on the SEC’s XXXXX filing system (or other successor electronic filing system)), hold a conference call to discuss such reports and the results of operations for the relevant reporting period and (2) if reports required by paragraphs (a)(1), (a)(2) and (a)(3) of this Section 4.03 are not available on the SEC’s XXXXX filing system (or other successor electronic filing system), the Company will also maintain a password protected website via an Intralinks site or other similar password protected website to which Holders and prospective purchasers of Notes are given access upon request to the Company and to which all of the reports required by this Section 4.03 are posted.

(d) In addition, the Company shall furnish to Holders and prospective purchasers of Notes designated by Holders, upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.04 Compliance Certificate.

(a) Each Issuer shall deliver to the Trustee, within ninety (90) days after the end of each fiscal year, beginning with the fiscal year ending December 31, 2010, an Officers’ Certificate stating that a review of the activities of each Issuer during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each Issuer has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge each Issuer has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of, or premium or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuer is taking or proposes to take with respect thereto.

(b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.03 hereof shall be accompanied by a written statement of the independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that an Issuer has violated any provisions of Article 4 or Article 5 hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation.

(c) So long as any of the Notes are outstanding, an Issuer will deliver to the Trustee, as promptly as practicable upon any Officer of such Issuer becoming aware of any Default or Event of Default with respect to such Issuer’s Notes, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto.

Section 4.05 Taxes and Tax Treatment of Units.

(a) The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except any such taxes that are being contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

(b) Each Issuer, and by its acceptance of the Units and/or the Notes, each Holder, hereby agrees (i) to treat the Units as separate indebtedness of the U.S. Issuers and the Canadian Issuers for U.S. and Canadian federal income tax purposes, (ii) to treat the acquisition of a Unit as the acquisition of a U.S. Note and Canadian Note which are represented by the Unit and to allocate the purchase price of the Unit between the U.S. Note and Canadian Note in the proportions 21.875% and 78.125%, respectively and (iii) that the Company and each Holder will not take any position on a tax return inconsistent with (i) and (ii), unless required by applicable law.

Each of the Issuers 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 each of the Issuers and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by

resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

(15) restrictions on the sale, lease or transfer of property or assets arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary.

(12) the issuance by any Restricted Subsidiary of the Company to the Company or to any Restricted Subsidiary of the Company of any Disqualified Stock; provided, however, that:

(a) any subsequent issuance or transfer of Equity Interests that results in any such preferred securities being held by a Person other than the Company or a Restricted Subsidiary of the Company; and

(b) any sale or other transfer of any such preferred securities to a Person that is not either the Company or a Restricted Subsidiary of the Company

shall be deemed, in each case, to constitute an issuance of such preferred securities by such Restricted Subsidiary that was not permitted by this clause (12);

(13) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided, however, that such Indebtedness is promptly extinguished;

(14) Indebtedness arising in connection with endorsement of instruments for deposit in the ordinary course of business;

(15) Indebtedness arising from indemnification, adjustment of purchase price, earn-out or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business or assets of the Company or any Restricted Subsidiary or Equity Interests of a Restricted Subsidiary, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or Equity Interests for the purpose of financing or in contemplation of any such acquisition;

(16) Indebtedness owed on a short-term basis to banks and other financial institutions incurred in the ordinary course of business of the Company and any Restricted Subsidiary with such banks or financial institutions that arises in connection with ordinary banking arrangements to manage cash balances of the Company and any Restricted Subsidiary;

(17) Indebtedness of the Company or any Restricted Subsidiary consisting of the financing of insurance premiums, in each case, in the ordinary course of business;

(18) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with a transaction meeting either one of the financial tests set forth in Section 5.01(a)(4);

(21) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount at any time outstanding, not to exceed the greater of (a) $50.0 million or (b) 4% of the Consolidated Net Tangible Assets of the Company.

(c) For purposes of determining compliance with this Section 4.09 and Section 4.12 hereof, in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (21) of Section 4.09(b) hereof, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to classify (or later classify or reclassify in whole or in part in its sole discretion) such item of Indebtedness in any manner that complies with this Section 4.09. Any Indebtedness under Credit Facilities on the date of this Indenture shall be considered incurred under Section 4.09(b)(1) above.

(d) The accrual of interest or preferred stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock 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 thereof is included in Fixed Charges of the Company as accrued. For purposes of determining compliance with any U.S. dollar denominated restriction on the incurrence of Indebtedness, the U.S. dollar equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed exceeded solely as a result of fluctuations in exchange rates or currency values.

Section 4.10 Asset Sales.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) such Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) except in the case of a Permitted Asset Swap, at least 75% of the consideration received in the Asset Sale by such Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents.

For purposes of this provision, each of the following will be deemed to be cash:

(a) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases such Company or such Restricted Subsidiary from or indemnifies against further liability;

(b) any securities, notes or other obligations received by such Company or any such Restricted Subsidiary from such transferee that are converted by such Company or such Restricted Subsidiary into cash within 120 days after such Asset Sale, to the extent of the cash received in that conversion;

(c) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale; provided that the aggregate Fair Market Value of such Designated Non-cash Consideration, taken together with the Fair Market Value at the time of receipt of all other Designated

Non-cash Consideration received pursuant to this clause (c) less the amount of Net Proceeds previously realized in cash from prior Designated Non-cash Consideration is less than $5.0 million; and

(d) any property, stock or assets of the kind referred to in clauses (1), (3) or (4) of Section 4.10(b) hereof.

(b) Within 365 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 an amount equal to such Net Proceeds, at its option:

(1) to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business (provided that in the case of any such acquisition of Capital Stock, after giving effect thereto, the Permitted Business is or becomes a Restricted Subsidiary of the Company);

(2) to repay Indebtedness that is secured by a Permitted Lien on any assets that were sold in such Asset Sale;

(3) to make a capital expenditure;

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business;

(5) in the case of an Asset Sale by a Restricted Subsidiary that is not a Guarantor, to repay, repurchase or redeem Indebtedness of the Company or any Restricted Subsidiary that is not contractually subordinated in right of payment to the Notes; or

(6) any combination of the foregoing clauses (1) through (5).

(c) In the case of clauses (1), (3) and (4) of Section 4.10(b) hereof, the Company (or the applicable Restricted Subsidiary, as the case may be) will be deemed to have complied with its obligations in Section 4.10(b) hereof if it enters into a binding commitment to acquire such assets or Capital Stock or make such capital expenditure prior to 365 days after the receipt of the applicable Net Proceeds; provided that such binding commitment will be subject only to customary conditions and such acquisition or expenditure is completed within 180 days following the expiration of the aforementioned 365-day period. If the acquisition or expenditure contemplated by such binding commitment is not consummated on or before such 180th day, and the Company (or the applicable Restricted Subsidiary, as the case may be) has not applied the applicable Net Proceeds for another purpose permitted by paragraphs (a) or (b) of this Section 4.10 on or before such 180th day, such commitment shall be deemed not to have been a permitted application of Net Proceeds.

(d) Pending the final application of any Net Proceeds of an Asset Sale, the Company (or the applicable Restricted Subsidiary) may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(e) Any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (b) and (c) of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, within forty-five (45) days thereof, the Issuers will make a joint offer (an “Asset Sale Offer”) to all holders of Notes and all holders of other Indebtedness ranking pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets in accordance with Section 3.08 hereof to purchase, prepay or redeem the maximum principal amount of Notes as Units and such other pari passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company and its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this

Indenture. If the aggregate principal amount of Notes as Units and other pari passu Indebtedness tendered into (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes as Units and such other pari passu Indebtedness to be purchased on a pro rata basis, based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(f) The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to a Change of Control Offer or an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control or Asset Sale provisions of Section 3.08 hereof or this Section 4.10, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.08 hereof or this Section 4.10 by virtue of such compliance.

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 (other than transactions with entities on an arms-length basis existing on the date of this Indenture) (each, an “Affiliate Transaction”), involving aggregate payments or consideration in excess of $500,000 for any Affiliate Transaction or in excess of $2.5 million per year for all Affiliate Transactions unless:

(1) the Affiliate Transaction is on terms that are no less favorable to such Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by such Company or such Restricted Subsidiary with an unrelated Person; and

(2) such Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, a resolution of the Board of Directors of such Company set forth in an Officers’ Certificate of the Company certifying that such Affiliate Transaction complies with this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of such Company; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million (other than a Development Project Acquisition), an opinion as to the fairness to such Company or such Restricted 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 4.11(a) hereof:

(1) any employment or consulting agreement, employee benefit plan, stock option or stock ownership plan, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto and issuances of Capital Stock, options, warrants or other rights to acquire Capital Stock, in each case, pursuant thereto;

(2) transactions between or among the Company and/or the Company’s Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) payment of reasonable and customary compensation (including bonuses) fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise) of officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries;

(5) any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company;

(6) Permitted Investments and Restricted Payments that do not violate Section 4.07 hereof;

(7) loans or advances to employees in the ordinary course of business not to exceed $2.0 million in the aggregate at any one time outstanding;

(8) transactions relating to the purchase or sale of Hydrocarbons, the lease of storage capacity or the transportation of Hydrocarbons, in each case with investors in the Company or its Affiliates entered into in the ordinary course of business consistent with past practice;

(9) all transactions described under the “Certain Relationships and Related Party Transactions” section of the Offering Memorandum and MLP Formation Transactions; and

(10) the payments to Affiliates made in accordance with the terms of, and in an amount not to exceed that required by, the Operating Agreement in effect as of the date of this Indenture.

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 upon any of their property or assets, now owned or hereafter acquired, unless the Notes or any Note Guarantee of such Restricted Subsidiary, as applicable, is secured on an equal and ratable basis (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes or such Note Guarantee, as the case may be) 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 shall not, and shall 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 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, partnership or other 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 of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) If a Change of Control occurs, each Holder will have the right to require the Issuers to jointly repurchase all or any part of that Holder’s Notes as Units pursuant to this Section 4.15 (a “Change of Control Offer”). Any such repurchase of the Notes shall include the U.S. Notes and the Canadian Notes on a pro rata basis based on the aggregate principal amount of the Notes outstanding at the time of repurchase. In the Change of Control Offer, the Issuers will jointly offer the Holders a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased as Units, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within thirty (30) days following any Change of Control, the Issuers will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the purchase date, which shall be no earlier than 10 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

(3) that any Unit (and corresponding Notes) not tendered will continue to accrue interest;

(4) that, unless the Issuers default in the payment of the Change of Control Payment, any Units (and corresponding 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 as Units purchased pursuant to a Change of Control Offer will be required to surrender the Units (and corresponding Notes), with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer a beneficial interest in the Units 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 Units (and corresponding Notes) delivered for purchase, the serial number for Units held in definitive form and a statement that such Holder is withdrawing his election to have the Notes purchased as Units; and

(7) that Holders whose Units (and corresponding Notes) are being purchased only in part will be issued new Units (and corresponding Notes) equal in principal amount to the unpurchased portion of the Units (and corresponding Notes) surrendered, which unpurchased portion, must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder 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 this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

(b) On the Change of Control Payment Date, the Issuers will jointly, to the extent lawful:

(1) accept for payment all Notes or portions of Notes properly tendered as Units pursuant to the Change of Control Offer;

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered as Units; and

(3) deliver or cause to be delivered to the Trustee the Units (and corresponding Notes) properly accepted together with an Officers’ Certificate of each Issuer stating the aggregate principal amount of Notes or portions of Notes as Units being purchased by the Issuers.

(c) The Paying Agent will promptly mail to each Holder properly tendered the Change of Control Payment for such Units (and corresponding Notes), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Unit (and corresponding Notes) equal in principal amount to any unpurchased portion of the Units (and corresponding Notes) surrendered, if any. The Issuers will jointly announce the results of the Change of Control Offer to the Holders on or as soon as practicable after the Change of Control Payment Date.

(d) The Issuers will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.01(a) through 3.01(c) hereof unless and until there is a default in payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer by an Issuer or a third party may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

Section 4.16 Payments for Consent.

The Company 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 for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 4.17 Additional Note Guarantees.

If the Company or any of its Restricted Subsidiaries acquires or creates another Subsidiary (other than an Excluded Subsidiary or an Unrestricted Subsidiary) after the date of this Indenture, then that Subsidiary will become a Guarantor of the Notes and execute a supplemental indenture in substantially the form attached as Exhibit F to this Indenture and deliver an Opinion of Counsel satisfactory to the Trustee within thirty (30) business days of the date on which it was acquired or created.

Section 4.18 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of the Company may designate any Restricted Subsidiary (other than an Issuer) to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by such 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 of the Company certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness 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 (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be in existence following such designation.

Section 4.19 Additional Amounts.

(a) All payments made by or on behalf of an Issuer or any Guarantor (each a “Payor”) under or with respect to the Notes or any Note Guarantee will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other similar liabilities related thereto) (collectively, “Taxes”) imposed or levied by or on behalf of any jurisdiction in which such Payor is organized, resident or doing business for tax purposes or from or through which such Payor (or its agents) makes any payment on the Notes or any Note Guarantee or any department or political subdivision thereof (each, a “Relevant Taxing Jurisdiction”), unless such Payor is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If a Payor is so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Notes or any Note Guarantee, such Payor, subject to the exceptions stated below, will pay such additional amounts (“Additional Amounts”) as may be necessary such that the net amount received in respect of such payment by each holder after such withholding or deduction (including withholding or deduction attributable to Additional Amounts payable hereunder) will not be less than the amount the holder would have received if such Taxes had not been required to be so withheld or deducted.

(b) A Payor will not, however, pay Additional Amounts to a holder or beneficial owner of Notes:

(i) with which the Payor does not deal at arm’s length (for the purpose of the Income Tax Act (Canada)) at the time of making such payment,

(ii) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the existence of any present or former connection between a Holder (or the beneficial owner of, or person ultimately entitled to obtain an interest in , such Notes, including a fiduciary, settler, beneficiary, member, partner, shareholder or other equity interest owner of , or possessor of power over, such holder or beneficial owner, if such holder or beneficial owner is an estate, trust, partnership, limited liability company, corporation or other entity) and the Relevant Taxing Jurisdiction (including being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, the Relevant Taxing Jurisdiction other than any connection resulting solely from the acquisition, ownership, or disposition of Notes, the receipt of payments thereunder and/or the exercise or enforcement of rights under any Notes or any Note Guarantee);

(iii) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the failure of the holder or beneficial owner of Notes, to the extent such holder or beneficial owner is legally eligible to do so, to satisfy any certification, identification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connection with the Relevant Taxing Jurisdiction or arm’s length-relationship with the Payor and the holder or beneficial owner or

otherwise establishing the right to the benefit of an exemption from, or reduction in the rate of, withholding or deduction, if (a) such compliance is required by statute, treaty, regulation or administrative practice of a Relevant Taxing Jurisdiction as a precondition to exemption from, or reduction in the rate of deduction or withholding of, such Taxes imposed by the Relevant Taxing Jurisdiction (including, without limitation, a certification that the holder or beneficial owner is not resident in the Relevant Taxing Jurisdiction) and (b) the Payor has provided the Trustee with 30 days’ prior written notice of such requirement;

(iv) with respect to any estate, inheritance, gift, sales or any similar Taxes;

(v) if such holder is a fiduciary or partnership or person other than the sole beneficial owner of such payment and the Taxes giving rise to such Additional Amounts would not have been imposed on such payment had the holder been the beneficiary, partner or sole beneficial owner, as the case may be, of such Note;

(vi) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the presentation by the holder of any Note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(vii) with respect to any Tax imposed or levied by, or on behalf of, the United States of America or any State thereof or the District of Columbia (or any political subdivision of any of the foregoing);

(viii) with respect to any Taxes imposed on a payment to an individual and required to be made pursuant to the European Union Directive on the taxation of savings income which was adopted by the ECOFIN Council (the Council of the EU Finance and Economic Ministers), or any law implementing or complying with, or introduced to conform to, such directive, or pursuant to related measures entered into on a reciprocal basis between member states of the European Union and certain non-European countries and dependent or associated territories;

(ix) with respect to any Tax which is payable otherwise than by withholding from payments on or in respect of the Notes or any Note Guarantee; or

(x) any combination of items (i), (ii), (iii), (iv), (v), (vi), (vii), (viii) and (ix) of this Section 4.19(b).

(c) At least 30 calendar days prior to each date on which any payment under or with respect to the Notes or any Note Guarantee is due and payable, if a Payor will be obligated to pay Additional Amounts with respect to such payment (unless such obligation to pay Additional Amounts arises after the 35th day prior to the date on which such payment is due and payable, in which case it will be promptly thereafter), the Payor will deliver to the Trustee an Officers’ Certificate stating that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Trustee to pay such Additional Amounts to holders on the payment date. The Payor will promptly publish a notice in accordance with the provisions set forth in Section 13.01 hereof stating that such Additional Amounts will be payable and describing the obligation to pay such amounts.

(d) The Payors, jointly and severally, will indemnify and hold harmless the holders of Notes, and, upon written request of any Holder, reimburse such holder for the amount of (i) any Taxes levied or imposed by a Relevant Taxing Jurisdiction and payable by such holder in connection with payments made under or with respect to the Notes held by such holder or under any Note Guarantee; and (ii) any Taxes levied or imposed with respect to any reimbursement under the foregoing clause (i) or this clause (ii), 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 the Taxes giving rise to the reimbursement described in clauses (i) and/ or (ii) had not been imposed, provided, however, that the indemnification or reimbursement obligations provided for in this Section 4.19(d) shall not extend to Taxes for which the holder of the Notes would not have been eligible to receive payment of Additional Amounts hereunder by virtue of

clauses (b)(i) through (b)(x) above or to the extent such holder received Additional Amounts with respect to such payments.

(e) In addition, the Payor will pay any stamp, issue, registration, court, documentation, excise or other similar taxes, charges and duties, including any interest, penalties and any similar liabilities with respect thereto, imposed by any Relevant Taxing Jurisdiction at any time in respect of the execution, issuance, registration or delivery of the Notes, any Note Guarantee or any other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any Relevant Taxing Jurisdiction as a result of, or in connection with, any payments made pursuant to the Notes or any Note Guarantee and/or the enforcement of the Notes or any Note Guarantee and/or any other such document or instrument.

(f) The obligations described in this Section 4.19 will survive any termination, defeasance or discharge of the Indenture and will apply mutatis mutandis to any successor Person to any Payor and to any jurisdiction in which such successor is organized or is otherwise resident or doing business for tax purposes or any jurisdiction from or through which payment is made by such successor or its respective agents. Whenever this Indenture refers to, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to any Note, such reference shall include the payment of Additional Amounts or indemnification payments as described hereunder, if applicable.

Section 4.20 Changes in Covenants When Notes Rated Investment Grade.

(a) If at any time the Notes are assigned an Investment Grade Rating by both Rating Agencies and no Default or Event of Default has occurred and is continuing under this Indenture, the Company and its Restricted Subsidiaries will no longer be subject to the provisions of this Indenture described in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.18 and 5.01(a)(4)(i) hereof (collectively the “Suspended Covenants”).

(d) Compliance with the Suspended Covenants with respect to Restricted Payments made after the Reinstatement Date will be calculated in accordance with the terms of Section 4.07 hereof as though such Section had been in effect during the entire period of time from which the Notes are issued.

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.

(b) In the event of a declaration of acceleration of the Notes because an Event of Default has occurred and is continuing as a result of the acceleration of any Indebtedness under clause (5) of Section 6.01 hereof, the declaration of acceleration of the Notes shall be automatically annulled if the holders of any Indebtedness described in clause (5) of Section 6.01 hereof have rescinded the declaration of acceleration in respect of such Indebtedness within thirty (30) days of the date of such declaration; provided that (1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction, (2) all existing Defaults or Events of Default, except nonpayment of principal, premium or interest, if any, on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived and (3) remedies have not been taken with respect to collateral securing such Indebtedness.

Section 6.03 Other Remedies.

(a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or interest or premium, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

(b) 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 the aggregate principal amount of the then outstanding Units 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 Defaults in the payment of interest or premium, if any, on or the principal of, 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 Units may rescind an acceleration and its consequences, including any related payment default that resulted in such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

The Holders of a majority in aggregate principal amount of the then outstanding Units may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability. In addition, the Trustee may withhold from Holders notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest or premium, if any.

Section 6.06 Limitation on Suits.

(a) Subject to the provisions of Article 7 hereof, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense. Except to enforce the right to receive payment of principal, interest or premium, if any, when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

(1) such Holder has previously given the Trustee notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy;

(3) such Holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

(4) the Trustee has not complied with such request within sixty (60) days after the receipt of the request and the offer of security or indemnity; and

(b) A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, or premium or interest, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder; provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the

institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, or premium or interest, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection and the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel.

To the extent that the payment of any such compensation, expenses, disbursements, advances and any other amounts due to the Trustee and its agents and counsel and any other amounts due to the Trustee under Section 7.06 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

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 and its agents and attorneys for amounts due to the Trustee under Section 7.06 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

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

The Trustee may, upon written notice to the Issuers, fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

For this purpose, Legal Defeasance means that the Issuers 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) of this Section 8.02, 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 Issuers, 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, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2) the Issuers’ 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, and the Issuers’ and the Guarantors’ obligations in connection therewith; and

(4) this Article 8.

Subject to compliance with this Article 8, the Issuers may exercise their joint option under this Section 8.02 notwithstanding the prior exercise of their option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers 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 3.08, 4.03, 4.04, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18 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 Issuers and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this

Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuers’ 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(7) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

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

(1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, or interest and premium, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Issuers must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;

(2) in the case of Legal Defeasance under Section 8.02 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (a) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of this Indenture, there has been a change in the applicable U.S. federal income tax law to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred and (b) an opinion of counsel in Canada reasonably acceptable to the Trustee or an advance tax ruling from the Canada Revenue Agency (or successor agency) to the effect that the holders of the outstanding Notes will not recognize income, gain or loss for Canadian income tax purposes as a result of such Legal Defeasance and will be subject to Canadian income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance under Section 8.03 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal or Canadian income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal and Canadian income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which any Issuer or any of the Guarantors is a party or by which any Issuer or any of the Guarantors is bound;

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

(7) the Issuers must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including either of the Issuers acting as Paying Agent) as the Trustee may determine, to the applicable Holders of all sums due and to become due thereon in respect of principal, or premium or interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuers from time to time upon the joint request of the Issuers any money or non-callable Government Securities held by either of the Issuers as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Issuers.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, or premium or interest, if any, on any Note and remaining unclaimed for two years after such principal, or premium or interest, if any, has become due and payable shall be paid to the Issuers on their joint request or (if then held by either of the Issuers) will be discharged from such trust; and the applicable Holder will thereafter be permitted to look only the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuers cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than thirty (30) days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuers.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuers make any payment of principal of, or premium or interest, if any, on any Note following the reinstatement of its obligations, the Issuers will be subrogated to the rights of the applicable Holders to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9
AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders.

Notwithstanding Section 9.02 of this Indenture, without the consent of any Holder, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes and the Note Guarantees:

(1) to cure any ambiguity, defect or inconsistency;

(2) to provide for uncertificated Units or Notes in addition to or in place of certificated Units and Notes;

(3) to provide for the assumption of an Issuer’s or a Guarantor’s obligations to Holders of Notes and Note Guarantees by a successor to an Issuer’s or such Guarantor pursuant to Article 5 or Article 10 hereof;

(4) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights hereunder of any such Holder;

(5) to conform the text of this Indenture, the Notes or the Note Guarantees to any provision of the “Description of Notes” section of the Offering Memorandum, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Notes or the Note Guarantees, which intent may be evidenced by an Officers’ Certificate of the applicable Issuer or Guarantor to that effect;

(6) to provide for the issuance of Additional Units in accordance with the limitations set forth in this Indenture as of the date hereof;

(7) to allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes;

(8) to evidence and provide for the acceptance of appointment hereunder by a successor trustee pursuant to the requirements of this Indenture;

(9) to provide for the release of a Guarantee of the Notes which release is otherwise permitted under this Indenture and would not result in a Default or Event of Default; or

(10) to comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act of 1939, as amended.

Section 9.02 With Consent of Holders.

Except as provided below in this Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.08, 4.10 and 4.15 hereof), the Notes or the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Units (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Units and/or Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, or premium or interest, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Units (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Units and/or Notes). Section 2.08 hereof shall determine which Units are considered to be “outstanding” for purposes of this Section 9.02.

Upon the joint request of the Issuers accompanied by a resolution of their Boards of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture.

It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuers will mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of at least a majority in aggregate principal amount of the Units then outstanding may waive compliance in a particular instance by the Issuers and the Guarantors with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder of the Units affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Units held by a non-consenting Holder):

(1) reduce the principal amount of Units whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.08, 4.10 and 4.15 hereof);

(3) reduce the rate of or change the time for payment of interest, including default interest, on any Note;

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Units or a waiver of the payment default that resulted from such acceleration);

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

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, or interest or premium, if any, on the Notes;

(7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.08, 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;

(9) adversely affect the ranking of the Notes or any Note Guarantee; or

(10) make any change in the preceding amendment and waiver provisions.

Section 9.03 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.04 Notation on or Exchange of Units and Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. Each Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.05 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuers may not sign an amended or supplemental indenture until the Board of Directors of each Issuer approves it. In executing any amended or supplemental indenture, the Trustee will be provided with and (subject to Section 7.01 hereof) will be fully protected in relying upon an Officers’ Certificate of each of the Issuers and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 10
NOTE GUARANTEES

Section 10.01 Guarantees.

(a) Subject to this Article 10, each of the Guarantors (except the U.S. Issuers with respect to the U.S. Notes and the Canadian Issuers with respect to the Canadian Notes) hereby, jointly and severally, unconditionally guarantees (each, a “Note Guarantee”) to each Holder holding 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 Issuers hereunder or thereunder, that:

(1) the principal of, and interest and premium, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and interest and premium, if any, on the Notes, if lawful, and all other obligations of the Issuers to the Holders or the Trustee under this Indenture will be promptly paid in full or performed, all in accordance with the terms of this Indenture and the Notes; 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.

(b) 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.

(c) 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 with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, 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 Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that its Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(d) If any Holder or the Trustee is required by any court or otherwise to return to any Issuer, the Guarantors or any custodian, trustee, receiver, receiver-manager, interim receiver, liquidator or other similar official acting in relation to any Issuer or the Guarantors, any amount paid by either to the Trustee or such Holder, the Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(e) Each Guarantor agrees that it shall 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 the Note Guarantees, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of the 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 Guarantees.

Section 10.02 [Reserved]

Section 10.03 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Units and/or Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent preference, transfer or conveyance or a transfer at undervalue for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state, provincial or foreign law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.04 Execution and Delivery of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.01 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 10.01 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 a Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

The delivery of any Notes as Units by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the applicable Note Guarantees set forth in this Indenture on behalf of the applicable Guarantors. Neither the Issuers nor any Guarantor shall be required to make a notation on the Notes to reflect any Note Guarantee or any release, termination or discharge thereof provided for in this Indenture.

In the event that the Company or any of its Restricted Subsidiaries acquires or creates any Subsidiary after the date of this Indenture, if required by Section 4.17(a) hereof, the Company shall cause such Subsidiary to comply with the provisions of Section 4.17(a) hereof and this Article 10, to the extent applicable.

Section 10.05 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.06 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge or amalgamate with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company, an Issuer or another Guarantor, unless:

(1) immediately after giving effect to such transaction, no Default or Event of Default exists; and

(2) either:

(a) the Person acquiring the assets in any such sale or disposition or the Person formed by or surviving any such consolidation, merger or amalgamation (if other than the Guarantor) (the “Successor Guarantor”) assumes all the obligations of that Guarantor under its Note Guarantee and this Indenture pursuant to a supplemental indenture satisfactory to the Trustee; or

(b) subject to Section 5.01 hereof, the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation, Section 4.10 hereof.

In case of any such consolidation, merger, amalgamation, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the applicable Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the applicable Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such 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, merger or amalgamation of a Guarantor with or into the Company, an Issuer 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, an Issuer or another Guarantor.

Section 10.06 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, amalgamation, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.10 hereof then the corporation acquiring the property will be released and relieved of any obligations under the applicable Note Guarantee;

(b) In the event of any sale or other disposition of Capital Stock of any Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the

Company, if the sale or other disposition does not violate Section 4.10 hereof and the Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition, then such Guarantor will be released and relieved of any obligations under its Note Guarantees;

provided, in both cases, that the Net Proceeds of such sale or other disposition are applied in accordance with Section 4.10 hereof. Upon delivery by the applicable Issuer 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 Guarantor 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 the Guarantor from its obligations under its Note Guarantees.

(c) Upon designation of any Restricted Subsidiary that is a 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 Guarantees.

(d) Upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof, each Guarantor will be released and relieved of any obligations under its Note Guarantees.

(e) Immediately prior to and in connection with a Qualified MLP IPO and the MLP Formation Transactions, each of Xxxxx Holdings I and Xxxxx Holdings II will be released and relieved of any obligations under its Note Guarantees.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.06 will remain liable for the full amount of principal of, premium on, if any, and interest, if any, on the applicable Notes and for the other obligations of such Guarantor under this Indenture as provided in this Article 10.

ARTICLE 11
SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:

(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 Issuers, have been delivered to the Trustee for cancellation; or

(b) all Notes that have not been delivered to the Trustee for cancellation (i) have become due and payable by reason of the mailing of a notice of redemption or otherwise, (ii) will become due and payable within one year or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers, and an Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination 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, if any, and accrued interest to the date of maturity or redemption;

(2) in respect of clause (1)(b) of this Section 11.01, no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from

the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which an Issuer or any Guarantor is a party or by which an Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);

(3) any Issuer or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and

(4) the Issuers have 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 Issuers 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 clause (1)(b) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

The U.S. Notes will be payable as to principal, premium, if any, and interest, if any, at the office or agency of the Paying Agent and Registrar within the City and State of New York, or, at the option of the U.S. Issuer, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium on, if any, and interest, if any, on all U.S. Notes and all other U.S. Notes the Holders of which will have provided wire transfer instructions to the U.S. Issuers or the Paying Agent.

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 U.S. Issuers’ and Canadian Issuers’ Obligations under the U.S. Notes and the Canadian Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and
