“Consolidated Interest Expense” means, for any period, the total interest expense of the Company and the Restricted Entities for such period, whether paid or accrued and whether or not capitalized (including amortization of debt issuance costs and original issue discount, non-cash interest payments, the interest component of any deferred payment obligations, the interest component of all payments associated with Capital Lease Obligations and Attributable Debt, commissions, discounts and other fees and charges incurred in respect of letter of credit or bankers’ acceptance financings), and net of the effect of all payments made or received pursuant to Hedging Obligations.

“Consolidated Leverage Ratio” as of any date of determination means the ratio of (x) the aggregate amount of Indebtedness of the Company and the Restricted Entities as of such date of determination to (y) Consolidated Operating Cash Flow for the most recent four consecutive fiscal quarters ending prior to such date of determination for which financial information is available (the “Reference Period”); provided, however, that:

(1) if the transaction giving rise to the need to calculate the Consolidated Leverage Ratio is an Incurrence of Indebtedness, the amount of such Indebtedness shall be calculated after giving effect on a pro forma basis to such Indebtedness;

(2) if the Company or any Restricted Entity has repaid, repurchased, defeased or otherwise discharged any Indebtedness that was outstanding as of the end of such fiscal quarter or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged on the date of the transaction giving rise to the need to calculate the Consolidated Leverage Ratio (other than, in each case, Indebtedness Incurred under any revolving credit agreement), the aggregate amount of Indebtedness shall be calculated on a pro forma basis and Consolidated Operating Cash Flow shall be calculated as if the Company or such Restricted Entity had not earned the interest income, if any, actually earned during the Reference Period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness;

(3) if since the beginning of the Reference Period the Company or any Restricted Entity shall have made any Asset Disposition, the Consolidated Operating Cash Flow for the Reference Period shall be reduced by an amount equal to the Consolidated Operating Cash Flow (if positive) directly attributable to the assets which are the subject of such Asset Disposition for the Reference Period or increased by an amount equal to the Consolidated Operating Cash Flow (if negative) directly attributable thereto for the Reference Period;

(4) if since the beginning of the Reference Period the Company or any Restricted Entity (by merger or otherwise) shall have made an Investment in any Restricted Entity (or any Person which becomes a Restricted Entity) or an acquisition of assets which constitutes all or substantially all of an operating unit of a business, Consolidated Operating Cash Flow for the Reference Period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition had occurred on the first day of the Reference Period; and

(5) if since the beginning of the Reference Period any Person (that subsequently became a Restricted Entity or was merged with or into the Company or any Restricted Entity since the beginning of such Reference Period) shall have made any Asset Disposition, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (3) or (4) above if

-7-

made by the Company or a Restricted Entity during the Reference Period, Consolidated Operating Cash Flow for the Reference Period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition had occurred on the first day of the Reference Period.

For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in accordance with GAAP in good faith by a responsible financial or accounting Officer of the Company. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Hedging Obligation applicable to such Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). If any Indebtedness is Incurred under a revolving credit facility and is being given pro forma effect, the interest on such Indebtedness shall be calculated based on the average daily balance of such Indebtedness for the four fiscal quarters subject to the pro forma calculation to the extent such Indebtedness was Incurred solely for working capital purposes.

“Consolidated Net Income” means, for any period, the net income of the Company and its consolidated Restricted Entities; provided, however, that there shall not be included in such Consolidated Net Income:

(1) any net income of any Person (other than the Company) if such Person is not a Restricted Entity, except that:

(A) subject to the exclusion contained in clauses (3), (4) and (5) below, the Company’s equity in the net income of any such Person for such period shall be included in such Consolidated Net Income up to the aggregate amount of cash actually distributed by such Person during such period to the Company or a Restricted Entity as a dividend or other distribution (subject, in the case of a dividend or other distribution paid to a Restricted Entity, to the limitations contained in clause (2) below); and

(i) The Notes offered and sold to QIBs in reliance on Rule 144A shall be issued initially in the form of one or more 144A Global Notes, which shall be deposited with, or on behalf of, DTC, or will remain in the custody of the Trustee, as custodian, pursuant to an agreement between DTC and the Trustee.

(ii) The Notes offered and sold in reliance on Regulation S shall be issued initially in the form of one or more Regulation S Global Notes, which shall be deposited with, or on behalf of, the Trustee as custodian for DTC.

(iii) In connection with the resale of Notes to an Institutional Accredited Investor, beneficial interests in any of the Global Notes may be exchanged for interests in a separate note in registered form, without interest coupons (the “IAI Global Note”), which will be deposited with, or on behalf of, a custodian for DTC as described in (i) and (ii) above.

(iv) Unrestricted Global Notes shall be issued in accordance with Sections 2.06(b)(vi), 2.06(d)(ii) and 2.06(d)(iii) and shall be deposited, duly executed by the Issuers and authenticated by the Trustee as hereinafter provided.

(v) Notes issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto).

Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate principal amount at maturity of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount at maturity of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount at maturity of outstanding Notes represented thereby shall be made by the Trustee or the custodian, at the direction of the Trustee, in accordance with instructions given by the holder thereof as required by Section 2.06 hereof.

Section 2.02. Execution and Authentication.

The Notes shall be executed on behalf of the Issuers by two Officers of each Issuer or an Officer and an Assistant Secretary of each Issuer. Such signature may be either manual or facsimile.

If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless.

-32-

A Note shall not be valid until the Trustee manually signs the certificate of authentication on the Note. Such signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee shall authenticate (i) Notes for original issue on the Issue Date not to exceed $750,000,000 aggregate principal amount at maturity upon a Company Request, and (ii) subject to Sections 4.06 and 4.09, Additional Notes, in each case upon a Company Request. Each such Company Request shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, whether the Notes are to be Notes or Additional Notes and whether the Notes are to be issued as Definitive Notes or Global Notes or such other information as the Trustee may reasonably request. Any Additional Notes shall be part of the same issue as the Notes being issued on the Issue Date and will vote on all matters as one class with the Notes being issued on the Issue Date. For the purposes of this Indenture, except for Section 4.06 and the definition of “Permitted Liens”, references to the Notes include Additional Notes, if any. In addition, with respect to authentication pursuant to clause (ii) of the first sentence of this paragraph, the first such written order from the Issuers shall be accompanied by an Opinion of Counsel of the Issuers stating that the issuance of the Additional Notes does not give rise to an Event of Default, complies with this Indenture and has been duly authorized by the Issuers.

The Trustee may appoint an authenticating agent to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same right as an Agent to deal with the Issuers or an Affiliate.

The Trustee shall have the right to decline to authenticate and deliver any Notes under this Section if the Trustee, being advised by counsel, reasonably determines that such action may not lawfully be taken, if its own rights, duties or immunities under the Notes and this Indenture are affected in a manner that is not reasonably acceptable to the Trustee or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to existing Noteholders.

Section 2.03. Registrar and Paying Agent.

The Issuers shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”), an office or agency located in the Borough of Manhattan, The City of New York, State of New York where Notes may be presented for payment (“Paying Agent”) and an office or agency where notices and demands to or upon the Issuers in respect of the Notes and this Indenture may be served. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuers may have one or more co-registrars and one or more additional paying agents. Neither the Company nor any Affiliate of the Company may act as Paying Agent. The Issuers may change any Paying Agent, Registrar or co-registrar without notice to any Noteholder.

The Issuers shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Issuers shall notify the Trustee of the name and address of any such Agent. If the Issuers fail to maintain a Registrar or Paying Agent, or agent for service of notices and demands, or fail to give the foregoing notice, the Trustee shall act as such. The Issuers initially appoint the Trustee as Registrar, Paying Agent, and agent for service of notices and demands in connection with the Notes.

Section 2.04. Paying Agent to Hold Money in Trust.

On or before each due date of the principal of and interest on any Notes, the Issuers shall deposit with the Paying Agent a sum sufficient to pay such principal and interest so becoming due. The Issuers at any time may require a Paying Agent to pay all

-33-

money held by it to the Trustee and the Trustee may at any time during the continuance of any Payment Default, upon written request to a Paying Agent, require such Paying Agent to forthwith pay to the Trustee all sums so held in trust by such Paying Agent together with a complete accounting of such sums. Upon doing so, the Paying Agent shall have no further liability for the money.

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 Noteholders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the holders of Notes and the Issuers shall otherwise comply with TIA § 312(a).

Section 2.06. Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or to another nominee of the Depository, or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. Global Notes will be exchanged by the Issuers for Definitive Notes if, and only if, (i) the Company delivers to the Trustee notice from the Depository that it is unwilling or unable to continue to act as Depository or that it ceases to be a clearing agency registered under the Exchange Act and, in either case, a successor Depository is not appointed by the Company, (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Definitive Notes or (iii) an Event of Default has occurred or is continuing and the Registrar has received a request from the Depository to issue Definitive Notes. Upon the occurrence of any of the preceding events in clauses (i) (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depository shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.09 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.09 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depository, in accordance with the provisions of this Indenture and the Applicable Procedures.

Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount at maturity of the relevant Global Note(s) pursuant to Section 2.06(h) hereof. Transfers by an owner of a beneficial interest in the Rule 144A Global or the IAI Global Note to a transferee who takes delivery of such interest through the Regulation S Global Note, whether before or after the expiration of the Restricted Period, shall be made only upon receipt by the Trustee of a certification from the transferor to the effect that such transfer is being made in accordance with Regulation S or (if available) Rule 144 under the Securities Act.

Section 2.09. Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee shall authenticate temporary Notes.

Section 2.13. CUSIP Number.

The Issuers in issuing the Notes may use a “CUSIP,” “ISIN” or other similar number(s), and if so, the Trustee shall use the CUSIP, ISIN or other similar number(s) in notices of redemption or exchange as a convenience to holders, provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or other similar number(s) printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes.

Section 3.02. Selection by Trustee of Notes to Be Redeemed.

In the event that fewer than all of the Notes are to be redeemed, the Trustee shall select the Notes to be redeemed on either a pro rata basis or by lot, or such other method as it shall deem fair and equitable. The Trustee shall promptly notify the Company of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. The Trustee may select for redemption portions of the principal of Notes that have denominations larger than $2,000.

For all purposes of this Indenture unless the context otherwise requires, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03. Notice of Redemption.

At least 30 but not more than 60 days before a Redemption Date, the Company shall mail, or cause to be mailed, a notice of redemption by first-class mail to the Trustee and to each holder of Notes to be redeemed at its address as the same appears on the registry books maintained by the Registrar pursuant to Section 2.03 hereof.

The notice shall identify the Notes to be redeemed (including the CUSIP number(s) thereof) and shall state:

(1) the Redemption Date;

(2) the redemption price;

At the Company’s request (and upon at least five (5) days prior written notice), the Trustee shall give the notice of redemption in the Issuers’ names and at the Company’s sole expense.

Section 3.04. Effect of Notice of Redemption.

Once the notice of redemption described in Section 3.03 is mailed, Notes called for redemption become due and payable on the Redemption Date and at the redemption price, including any premium, plus interest accrued to the Redemption Date, if any. Upon surrender to the Paying Agent, such Notes shall be paid at the redemption price, including any premium, plus interest accrued to the Redemption Date, if any; provided that if the Redemption Date is after a regular interest payment record date and on or prior to the Interest Payment Date, the accrued interest shall be payable to the holder of the redeemed Notes registered on the relevant record date, and provided, further, that if a Redemption Date is a Legal Holiday, payment shall be made on the next succeeding Business Day and no interest shall accrue for the period from such Redemption Date to such succeeding Business Day.

On or prior to 10:00 A.M., New York City time, on each Redemption Date, the Issuers shall deposit with the Paying Agent in immediately available funds money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date other than Notes or portions thereof called for redemption on that date which have been delivered by the Issuers to the Trustee for cancellation.

On and after any Redemption Date, if money sufficient to pay the redemption price of and accrued interest on Notes called for redemption shall have been made available in accordance with the preceding paragraph, the Notes called for redemption will cease to accrue or accrete interest and the only right of the holders of such Notes will be to receive payment of the redemption price of and, subject to the first proviso in Section 3.04, accrued and unpaid interest on such Notes to the Redemption Date. If any Note called for redemption shall not be so paid, interest will be paid, from the Redemption Date until such redemption payment is made, on the unpaid principal of the Note and any interest not paid on such unpaid principal, in each case, at the rate and in the manner provided in the Notes.

Section 3.06. Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Trustee shall authenticate for a holder a new Note equal in principal amount at maturity to the unredeemed portion of the Note surrendered.

-59-

Available Cash from any Asset Disposition of an FCC License, Industry Canada License or any similar telecommunications license or any Capital Stock of the FCC License Subsidiary, MSV Canada Inc. or any other entity holding a telecommunications license is in excess of $10.0 million, the Net Available Cash from such Asset Disposition may not be applied as provided in this clause (A) and shall be immediately applied as required in clause (b) below; and

(B) second, to the extent of the balance of such Net Available Cash after application in accordance with clause (A) above:

(1) to the extent that such Net Available Cash is derived from an Asset Disposition of Collateral to make an offer to the holders of the Notes (and to holders of other Additional Secured Obligations that require such an offer) to purchase Notes (and such other Additional Secured Obligations) pursuant to and subject to the conditions contained in this Indenture; provided that such offer to holders of Notes is for no less than the Noteholders pro rata amount of such Net Available Cash (based on the Accreted Value of the Notes outstanding and the principal amount (or accreted value if issued with discount) of such Additional Secured Obligations); and

(2) to the extent that such Net Available Cash is not derived from any Asset Disposition of Collateral, to make an offer to holders of the Notes (and to holders of other secured Pari Passu Indebtedness that requires such an offer) to purchase Notes (and such other secured Pari Passu Indebtedness that require such an offer) pursuant to and subject to the conditions contained in this Indenture; provided, that such offer to holders of Notes is for no less than the Noteholders pro rata amount of such Net Available Cash (based on the Accreted Value of the Notes outstanding and the principal amount (or accreted value if issued with discount) of such Additional Secured Obligations);

provided, however, that in connection with any prepayment, repayment or purchase of Indebtedness pursuant to clause (3)(B) above, the Issuers or such Restricted Entity shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased; provided, however, that the prior proviso shall not affect the ability of the Company of the Restricted Entities to incur Indebtedness under Section 4.06(b).

Pending application of Net Available Cash that is not derived from Collateral pursuant to this covenant, such Net Available Cash shall be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit indebtedness. Pending application of Net Available Cash that is derived from Collateral pursuant to this covenant, such Net Available Cash shall be deposited into the Collateral Account.

(b) In the event of an Asset Disposition that requires the Issuers to make an Offer to purchase the Notes (and other Indebtedness) pursuant to Section 4.10(a)(3)(B) the Issuers shall purchase Notes tendered pursuant to an Offer by the Issuers for the Notes (and such other Indebtedness) (the “Offer”) at a purchase price of 100% of their Accreted Value (such other Indebtedness at a purchase price of 100% of its principal amount or, in the event such other Indebtedness was issued with significant original issue discount, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest (or, in respect of such other Indebtedness, such lesser price, if any, as may be provided for by the terms of such Indebtedness) in accordance with the procedures set forth in Section 4.10(c). If the aggregate purchase price of the Notes (and such other Indebtedness) tendered exceeds the Net

-60-

Available Cash allotted to their purchase, the Trustee will select the Notes and such other Indebtedness to be purchased on a pro rata basis but in round denominations, which in the case of the Notes will be denominations of $2,000 principal amount at maturity or multiples thereof. The Company shall not be required to make such an Offer to purchase Notes (and other Indebtedness) pursuant to Section 4.10(a)(3)(B) if the Net Available Cash available therefrom is less than $15.0 million (which lesser amount shall be carried forward for purposes of determining whether such an Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). To the extent that the aggregate amount of Notes and other Indebtedness tendered is less than the Net Available Cash required to be used to make an Offer to the holders of Notes and such Indebtedness, the Company may use such excess Net Available Cash for any other purpose not prohibited by this Indenture.

(c) Promptly, and in any event within 10 days after the Company becomes obligated to make an Offer pursuant to Section 4.10(a)(3)(B), the Company shall deliver to the Trustee and send, by first-class mail to each holder, a written notice stating that the holder may elect to have its Notes purchased by the Issuers either in whole or in part (subject to prorating as described in Section 4.10(b) in the event the Offer is oversubscribed) in integral multiples of $2,000 principal amount at maturity, at the applicable purchase price set forth in Section 4.10(b). The notice shall specify a purchase date not less than 30 days nor more than 60 days after the date of such notice (the “Purchase Date”) and shall contain such information concerning the business of the Issuers which the Issuers in good faith believe will enable such holders to make an informed decision and all instructions and materials necessary to tender Notes pursuant to the Offer, together with the information contained in clause (3).

(1) Not later than the date upon which written notice of an Offer is delivered to the Trustee as provided below, the Company shall deliver to the Trustee an Officer’s Certificate as to (A) the amount of the Offer (the “Offer Amount”), including information as to any other Additional Secured Obligations or secured Pari Passu Indebtedness included in the Offer, (B) the allocation of the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made and (C) the compliance of such allocation with the provisions of Section 4.10(a) and (b). On such date (i) to the extent the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made is not derived from Collateral, the Company shall irrevocably deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) in Temporary Cash Investments, maturing on the last day prior to the Purchase Date or on the Purchase Date if funds are immediately available by open of business, an amount equal to the Offer Amount to be held for payment in accordance with the provisions of this Section and (ii) to the extent the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made is derived from Collateral, the Company shall irrevocably deposit in the Collateral Account an amount equal to the Offer Amount to be held for payment in accordance with the provisions of this Section. If the Offer includes other Additional Secured Obligations or Secured Pari Passu Indebtedness, the portion of the deposit described in the preceding sentence that is applicable to such Additional Secured Obligations or secured Pari Passu Indebtedness may be made with any other paying agent pursuant to arrangements satisfactory to the Trustee. Upon the expiration of the period for which the Offer remains open (the “Offer Period”), the Company shall deliver to the Trustee for cancellation the Notes or portions thereof which have been properly tendered to and are to be accepted by the Company. The Trustee shall, on the Purchase Date, mail or deliver payment (or cause the delivery of payment) to each tendering holder in the amount of the purchase price. In the event that the aggregate purchase price of the Notes delivered by the Company to the Trustee is less than the Offer Amount applicable to the Notes, the Trustee shall deliver the excess to the Company immediately after the expiration of the Offer Period for application in accordance with this Section 4.10.

-61-

(2) Holders electing to have Notes purchased shall be required to surrender the Notes, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Purchase Date. Holders shall be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the Purchase Date, a facsimile transmission or letter setting forth the name of the holder, the principal amount at maturity of the Notes which were delivered for purchase by the holder and a statement that such holder is withdrawing his election to have such Notes purchased. Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

(3) At the time the Company delivers Notes to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officer’s Certificate stating that such Notes are to be accepted by the Company pursuant to and in accordance with the terms of this Section. Notes shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering holder.

(d) The Company will not, and will not permit any Restricted Subsidiary to, and each Restricted Entity will not, engage in any Asset Swaps, unless:

(1) at the time of entering into such Asset Swap and immediately after giving effect to such Asset Swap, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;

(2) the Related Business Assets that are the subject of such Asset Swap have a substantially comparable fair market value;

(3) in the event such Asset Swap involves the transfer by the Company or any Restricted Entity of assets having an aggregate fair market value, as determined by the Board of Directors of the General Partner in good faith, in excess of $10 million, the terms of such Asset Swap have been approved by a majority of the members of the Board of Directors of the Company; and

(4) any cash received shall be applied in accordance with Section 4.10(a)(3).

(e) To the extent that the provisions of any securities laws or regulations conflict with provisions of 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 hereunder and this Section 4.10 by virtue of its compliance with such securities laws or regulations.

Section 4.11. Limitation on Transactions with Affiliates.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, and each Restricted Entity shall not, enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the Company (an “Affiliate Transaction”) involving (together with any related Affiliate Transactions) aggregate consideration in excess of $10 million, unless:

(1) the terms of the Affiliate Transaction are not materially less favorable taken as a whole to the Company or such Restricted Entity than those that could be obtained at the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate; and

-62-

(2) if such Affiliate Transaction (together with any related Affiliate Transactions) involves an amount in excess of $15.0 million, the terms of the Affiliate Transaction are set forth in writing and a majority of the non-employee directors of the General Partner disinterested with respect to such Affiliate Transaction have determined in good faith that the criteria set forth in clause (1) are satisfied and have approved the relevant Affiliate Transaction.

(b) The provisions of the preceding paragraph (a) shall not prohibit:

(1) Restricted Payments, in each case permitted to be made pursuant to Section 4.08, and Permitted Investments;

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are fair to the Company and the Restricted Entities, in the reasonable determination of the Board of Directors of the General Partner or the senior management of the Company, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

Section 4.19. Maintenance of Insurance.

(a) The Company shall obtain, and shall cause the Restricted Subsidiaries to obtain, and the Restricted Entities shall obtain, prior to the launch of each satellite and shall maintain launch insurance with respect to each satellite launch covering the period from the launch to 180 days following the launch of each satellite on such terms (including coverage period, exclusions, limitations on coverage, co-insurance, deductibles and coverage amount) as is customary in the industry for similar persons at the time of such launch. In the event that the Company constructs a spare satellite (“ground spare”), the amount of coverage may be reduced if it is in the best interest of the Company, but in no event to an amount less than the cost to launch and insure the launch for the ground spare.

(b) The Company shall, and shall cause the Restricted Subsidiaries to, and the Restricted Entities shall, procure and maintain Full In-orbit Insurance, with respect to each satellite they own (other than satellites that are in orbit as of the Issue Date) unless at the time of securing such Full In-Orbit Insurance there has occurred and is continuing a material adverse change in market conditions for the obtaining of Full In-orbit Insurance since March 31, 2004 such that it would be commercially unreasonable for the Company and the Restricted Entities to maintain such Full In-orbit Insurance. Such Full In-Orbit Insurance shall be on such terms (including exclusions, limitations on coverage, coinsurance, deductibles and coverage amount) as is customary in the industry for similar persons at the time of procurement; provided, however, that with the exception of the initial procurement of Full In-Orbit Insurance for a satellite that experienced a loss that either occurred during the launch insurance coverage period or was otherwise covered by launch insurance, in no event shall the coverage amount be less than the net book value of the satellite, assuming straight-line depreciation over the life of the satellite, as adjusted for impairment. In the event that the expiration and non-renewal of Full In-Orbit Insurance for such a satellite resulting from a claim of loss under such policy causes a failure to comply with the proviso to the immediately preceding sentence the Company shall be deemed to be in compliance with the proviso to the immediately preceding sentence for the 120 days immediately following such expiration or non-renewal, provided that the Company procures such Full In-Orbit Insurance as necessary to comply with the preceding proviso within 120 day period.

(c) The Company shall cause all insurance maintained with respect to any Collateral to name the Collateral Agent, for its benefit and for the benefit of holders of the Notes, the holders of Additional Notes and the holders of Additional Secured Obligations, as additional insured or loss payee, as appropriate.

Insurance policies obtained or renewed after the Issue Date required by the foregoing paragraphs (a) and (b) shall:

(1) contain no exclusions other than exclusions as may be customary for policies of such type and such other exclusions or limitations of coverage as may be applicable to a substantial portion of satellites of the same model or relating to systemic failures or anomalies as are then customary in the satellite insurance market; and

(2) provide coverage for all risks of loss and damage to the satellite.

In the event that the Company receives Net Insurance Proceeds relating to any satellite, the Company shall apply such Net Insurance Proceeds in the manner provided under Section 4.18.

-69-

of the Issuers or any tenant, a release of Hazardous Materials onto the Collateral or any portion thereof or onto any other property that would result in the incurrence by the Issuers of material costs or liabilities under applicable Environmental Laws.

After any such acceleration but before a judgment or decree based on acceleration is obtained by the Trustee, the holders of a majority in aggregate principal amount at maturity of outstanding Notes by notice to the Trustee may rescind and cancel such acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of accelerated Accreted Value, principal, premium, if any, or interest that has become due solely because of the acceleration, have been cured or waived, (ii) to the extent the payment of such interest is lawful, interest (at the same rate specified in the Notes) on overdue installments of interest and overdue Accreted Value, premium, if any, or interest, which has become due otherwise than by such declaration of acceleration, has been paid, (iii) the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee its expenses, disbursements and advances, (iv) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (v) in the event of the cure or waiver of a Default or Event of Default described in Section 6.01(7) or (8), the Trustee has received an Officer’s Certificate and an Opinion of Counsel that such Default or Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

Section 6.03. Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may (i) pursue any available remedy by proceeding at law or in equity to collect the payment of Accreted Value or principal, as the case may be of, or premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture and may take any necessary action requested of it as Trustee to settle, compromise, adjust or otherwise conclude any proceedings to which it is a party or (ii) instruct the Collateral Agent to exercise any available remedies under the Security Documents.

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 Notes in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.04. Waiver of Past Defaults and Events of Default.

Subject to Sections 6.02, 6.07 and 8.02 hereof, the holders of a majority in aggregate principal amount at maturity of the Notes then outstanding have the right to waive any existing Default or Event of Default or compliance with any provision of this Indenture, the Security Documents or the Notes. 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 Event of Default or impair any right consequent thereto.

-75-

Section 6.05. Control by Majority.

The holders of a majority in aggregate principal amount at maturity of the Notes then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, and, subject to the terms of the Security Documents, the Collateral Agent or exercising any trust or power conferred on the Trustee by this Indenture or the Security Documents. The Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of another holder not taking part in such direction, and the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, determines that the action so directed may not lawfully be taken or if the Trustee in good faith shall, by a Responsible Officer, determine that the proceedings so directed may involve it in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 6.06. Limitation on Suits.

Subject to Section 6.07 below, a holder may not institute any proceeding with respect to this Indenture or any Security Document, or for the appointment of a receiver or trustee, or pursue any remedy with respect to this Indenture, any Security Document or the Notes unless:

(1) such holder has previously given to the Trustee written notice of a continuing Event of Default;

(2) the registered holders of at least 25% in aggregate principal amount of the Notes or Accreted Value, as the case may be, then outstanding, have made written request and offered indemnity to the Trustee reasonably satisfactory to the Trustee to institute such proceeding as trustee; and

(3) the Trustee shall not have received from the registered holders of a majority in aggregate principal amount of the Notes or Accreted Value, as the case may be, then outstanding a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days.

A holder may not use this Indenture or the Security Documents to prejudice the rights of another holder or to obtain a preference or priority over another holder.

Section 6.07. Rights of Holders to Receive Payment.

-76-

Guarantors (or any other obligor on the Notes) for the whole amount of unpaid principal, premium and accrued interest remaining unpaid, together with interest on overdue principal, premium and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate then borne by the Notes, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim.

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the holders allowed in any judicial proceedings relative to the Issuers or the Guarantors (or any other obligor upon the Notes), its creditors or its property and the Trustee shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims or pursuant to the Security Documents and to distribute the same after deduction of its charges and expenses to the extent that any such charges and expenses are not paid out of the estate in any such proceedings and each custodian in any such judicial proceeding is hereby authorized by each holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof.

Nothing herein contained shall be deemed to authorize the Trustee or the Collateral Agent 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 thereof, or to authorize the Trustee to vote in respect of the claim of any holder in any such proceeding.

Section 6.10. Priorities.

Any money collected by the Trustee pursuant to this Article 6 or from the Collateral Agent pursuant to Article 11 of the Security Agreement or any other Security Document, or, after an Event of Default, any money or other property distributable in respect of the Issuers’ or Guarantors’ obligations under this Indenture or the Security Documents, shall be paid in the following order:

(1) FIRST: to the Trustee for all amounts due under Section 7.07 hereof;

(2) SECOND: to Noteholders for due and unpaid amounts of principal, premium, if any, and interest on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes held by each holder;

(3) THIRD: to the Company or as a court of competent jurisdiction may direct.

The Trustee may fix a record date and payment date for any payment to holders pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or the Security Documents or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable

-77-

attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and the Security Documents and use the same degree of care and skill in their exercise as a prudent person would exercise under the same circumstances in the conduct of such person’s own affairs.

-78-

provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts, or the statements or opinions stated therein).

However, the failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder except to the extent the Company is prejudiced thereby.

Notwithstanding the foregoing, the Company and the Guarantors need not reimburse the Trustee for any expense or indemnify it against any loss or liability incurred by the Trustee through its own negligence or willful misconduct.

To the extent resulting from or in connection with the execution, delivery, enforcement, performance, or administration of this Indenture, and except to the extent arising from the gross negligence, willful misconduct, or bad faith of the Trustee, the Issuers shall defend, indemnify, and hold harmless each Indemnified Party from and against any claims, demands, penalties, fines, liabilities, settlements, damages, costs, or expenses of whatever kind or nature, known or unknown, contingent or otherwise, arising out of, or in any way related to, (w) the presence, disposal, release, or threatened release of any Hazardous Materials which are on, from, or affecting soil, water, vegetation, buildings, personal property, persons, animals, or otherwise; (x) any personal injury (including wrongful death), property damage (real or personal) or natural resource damage arising out of or related to such Hazardous Materials; (y) any third party claim brought or threatened, settlement reached, or government order, or any policies or requirements of the Trustee, which are based upon or in any way related to such Hazardous Materials, including, without limitation, attorney and consultant fees and expenses, investigation and laboratory fees, court costs, and litigation expenses; and (z) any violations of Environmental Laws.

As security for the performance of the obligations of the Company and the Guarantors under this Section 7.07, the Trustee shall have a Lien secured by this Indenture and the Security Documents prior to the Notes upon the Collateral and upon all other property and funds held or collected by the Trustee as such, except funds paid by the Issuer or any Guarantor and held in trust to pay principal of and interest on particular Notes for the benefit of the holders of particular Notes under this Indenture. The Trustee shall be entitled to file a proof of claim in any bankruptcy proceeding as a secured creditor for any indemnification costs and for its reasonable compensation, fees and expenses under this Section 7.07

In addition and without prejudice to the rights provided to the Trustee under any of the provisions of this Indenture, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(7) or Section 6.01(8), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Bankruptcy Law or comparable expenses in the case of an Event of Default specified in Section 6.01(8).

The Company’s obligations under this Section 7.07 and the Lien referred to in this Section 7.07 shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture or any of the Security Documents and/or the termination of this Indenture or any of the Security Documents for any reason.

-83-

“Trustee” for purposes of this Section 7.07 shall include the Collateral Agent, the Sub -Collateral Agent and any co-trustee, separate trustee, co-collateral agent, sub-collateral agent or separate collateral agent and any predecessor Trustee and the Trustee in each of its capacities hereunder and to each agent, custodian and other Person employed to act hereunder; provided, however, that the negligence, bad faith or willful misconduct of any Trustee, co-trustee, separate trustee, co-collateral agent, sub-collateral agent, separate collateral agent or any such agent, custodian or other Person hereunder shall not affect the rights of any other Trustee or any such other agent, custodian or other Person hereunder.

Section 7.08. Replacement of Trustee.

The Trustee may resign by so notifying the Company and the Guarantors in writing. The holders of a majority in principal amount of the outstanding Notes may remove the Trustee by notifying the removed Trustee in writing and may appoint a successor Trustee with the Company’s written consent, which consent shall not be unreasonably withheld. The Company may remove the Trustee at its election if:

(1) the Trustee fails to comply with Section 7.10 hereof;

(2) the Trustee is adjudged bankrupt or insolvent;

(3) a receiver or other public officer takes charge of the Trustee or its property;

(4) the Trustee otherwise becomes incapable of acting; or

(5) a successor corporation becomes successor Trustee pursuant to Section 7.09 below.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee.

If a successor Trustee does not take office within 30 days after such retiring Trustee resigns or is removed, the retiring Trustee (at the expense of the Company), the Company or the holders of a majority in principal amount or Accreted Value, as the case may be, of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10 hereof, any holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately following such delivery, the retiring Trustee shall, subject to its rights under Section 7.07 hereof and payment of its charges hereunder, transfer all property held by it as Trustee to its successor, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture.

At any time or times, for the purpose of meeting the Legal Requirements of any jurisdiction in which any of the Collateral may at the time be located, the Company and the Trustee shall have power to appoint, and, upon the written request of (i) the Trustee or (ii) the holders of at least 25% of the outstanding principal amount at maturity of the Notes, the Company shall for such purpose join with the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Trustee either to act as co-trustee, jointly with the Trustee, or to act as separate trustee, co-collateral agent, sub-collateral agent or separate collateral agent of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section 7.13. If the Company does not join in such appointment within 15 days after the receipt by it of a request so to do, or in case an Event of Default has occurred and is continuing, the Trustee alone shall have power to make such appointment.

Should any written instrument from the Company be requested by any co-trustee or separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent so appointed for more fully confirming to such co-trustee or separate trustee such property, title, right or power, any and all such instruments shall, on request of such co-trustee or separate trustee or separate collateral agent, be executed, acknowledged and delivered by the Company.

Any co-trustee, separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent shall agree in writing to be and shall be subject to the provisions of the applicable Security Documents as if it were the Trustee thereunder (and the Trustee shall continue to be so subject).

Every co-trustee or separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent shall, to the extent permitted by law, but to such extent only, be appointed subject to the following terms, namely:

(a) The Notes shall be authenticated and delivered, and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustee hereunder, shall be exercised solely, by the Trustee.

(b) The rights, powers, duties and obligations hereby conferred or imposed upon the Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed by the Trustee or by the Trustee and such co-trustee or separate trustee jointly, or by the Trustee and such co-collateral agent, sub-collateral agent or separate collateral agent jointly as shall be provided in the instrument appointing such co-trustee, separate trustee or separate collateral agent, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee, separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent.

(c) The Trustee at any time, by an instrument in writing executed by it, with the concurrence of the Company evidenced by a Board Resolution, may accept the resignation of or remove any co-trustee, separate trustee or co-collateral agent, sub-collateral

-86-

agent or separate collateral agent appointed under this Section 7.13, and, in case an Event of Default has occurred and is continuing, the Trustee shall have power to accept the resignation of, or remove, any such co-trustee, separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent without the concurrence of the Company. Upon the written request of the Trustee, the Company shall join with the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee, separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent so resigned or removed may be appointed in the manner provided in this Section 7.13.

(d) No co-trustee, separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent hereunder shall be liable by reason of any act or omission of the Trustee, or any other such trustee, co-trustee, separate trustee, co-collateral agent, sub-collateral agent or separate collateral agent hereunder.

(e) The Trustee shall not be liable by reason of any act or omission of any co-trustee, separate trustee, co-collateral agent, sub-collateral agent or separate collateral agent.

(f) Any act of holders delivered to the Trustee shall be deemed to have been delivered to each such co-trustee, separate trustee or co-collateral agent, sub-collateral agent or separate collateral agent, as the case may be.

The Company and the Trustee hereby appoint BNY Trust Company of Canada as sub-collateral agent under the Security Documents covering Canadian Collateral (the “Sub-Collateral Agent”). The Sub-Collateral Agent shall have all of the rights, powers, duties and obligations conferred or imposed upon the Trustee in this Indenture in respect of any property covered by such appointment.

ARTICLE 8

AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 8.01. Without Consent of Holders.

The Company, Finance Co. and the Guarantors, when authorized by a Board Resolution of each of them, and the Trustee (and, in the case of the Security Documents, any other Person whose consent is required thereunder) may amend or supplement this Indenture, the Security Documents or the Notes or take any of the actions below without notice to or consent of any holder:

(1) to cure any ambiguity, manifest error, omission, defect, mistake or inconsistency or to conform this Indenture to the “Description of Notes” section in the Offering Memorandum;

(2) to provide for the assumption by a successor corporation of the obligations of the Issuers or any Guarantor under this Indenture;

(3) to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);

-87-

(4) to add Guarantees or Collateral with respect to the Notes, including any subsidiary guarantees;

(5) to add to the covenants of the Company or any of the Restricted Entities for the benefit of the holders of the Notes or to surrender any right or power conferred upon the Company or any of the Restricted Entities;

(6) to make any change that does not materially adversely affect the rights, taken as a whole, of any holder of the Notes;

(7) to comply with any requirement of the SEC in connection with the qualification of this Indenture under the Trust Indenture Act and to provide for a successor Trustee;

(8) to make any amendment to the provisions of this Indenture relating to the transfer, exchange and legending of Notes; provided, however, that (a) compliance with this Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any other applicable securities law and (b) such amendment does not materially and adversely affect the rights of holders to transfer Notes;

(9) to confirm and evidence the release, termination or discharge of any Guarantee or Lien with respect to or securing the Notes when such release, termination or discharge is provided for under this Indenture and to release a Guarantor from its obligations under its Guarantee or this Indenture in accordance with the applicable provisions of this Indenture; or

(10) to appoint a co-trustee, separate trustee, co-collateral agent, sub-collateral agent or collateral agent as provided in Section 7.13.

The consent of the holders of the Notes is not necessary under this Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

The Trustee is hereby authorized to join with the Issuers and the Guarantors in the execution of any supplemental indenture or supplement to the Security Documents authorized or permitted by the terms of this Indenture or the Security Agreement and to make any further appropriate agreements and stipulations which may be therein contained, but the Trustee shall not be obligated to enter into any such supplemental indenture which adversely affects its own rights, duties or immunities under this Indenture.

Section 8.02. With Consent of Holders.

Subject to Section 6.04, the Company, Finance Co., the Trustee (and, in the case of the Security Documents, any other Person whose consent is required thereunder) and the Guarantors, with the consent of the registered holders of a majority in aggregate principal amount at maturity of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes), may amend this Indenture or the Security Documents and may waive any past default or compliance with any provisions. Without the consent of each holder, however, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04 may not:

(1) reduce the amount of Notes whose holders must consent to an amendment;

(2) reduce the rate of or extend the time for payment of interest on any Note;

-88-

(3) reduce the principal or Accreted Value of or change the Stated Maturity of any Note;

(4) reduce the amount payable upon the redemption of any Note or make earlier the time at which any Note may be redeemed under Article 3 hereto or paragraph 5 of the Notes;

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

(6) impair the right of any holder of the Notes to receive payment of principal or Accreted Value of and interest on such holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes;

(7) make any change in the amendment provisions which require each holder’s consent or in the waiver provisions;

(8) make any change in the ranking or priority of any Note that would adversely affect the Noteholders;

(9) change the method of calculating Accreted Value;

(10) release any Guarantor from its Guarantee that is not otherwise permitted by this Indenture; or

(11) release substantially all of the Collateral.

After an amendment, supplement or waiver under this Section 8.02 or Section 8.01 becomes effective, the Company shall mail to the holders notice briefly describing the amendment, supplement or waiver; provided, however, the failure to give such notice to all holders of the Notes, or any defect therein, will not impair or affect the validity of the amendment, supplement or waiver.

Upon the request of the Company, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and upon the receipt by the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the holders as aforesaid and upon receipt by the Trustee of the documents described above or in Section 8.06 hereof, the Trustee shall join with the Issuers and the Guarantors in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed, the holders on such record date, or their duly designated proxies, and only such Persons shall be entitled to consent to such supplemental indenture, whether or not such holders remain holders after such record date; provided, that unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any such consent previously given shall automatically and without further action by any holder be canceled and of no further effect.

It shall not be necessary for the consent of the holders under this Section 8.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

-89-

Section 8.03. Revocation and Effect of Consents.

Until an amendment, supplement, waiver or other action becomes effective, a consent to it by a holder of a Note is a continuing consent conclusive and binding upon such holder and every subsequent holder of the same Note or portion thereof, and of any Note issued upon the transfer thereof or in exchange therefor or in place thereof, even if notation of the consent is not made on any such Note. Any such holder or subsequent holder, however, may revoke the consent as to its Note or portion of a Note, if the Trustee receives the notice of revocation, before the date the amendment, supplement, waiver or other action becomes effective.

Subject to the approval requirements of Section 8.02, after an amendment, supplement, waiver or other action becomes effective, it shall bind every holder. In the case of any amendment, supplement or waiver specified in clauses (1) through (11) of the first paragraph of Section 8.02, the amendment, supplement, waiver or other action shall bind each holder of a Note who has consented to it and every subsequent holder of a Note or portion of a Note that evidences the same debt as the consenting holder’s Note.

Section 8.04. Notation on or Exchange of Notes.

If an amendment, supplement, or waiver changes the terms of a Note, the Trustee may request the holder of the Note to deliver it to the Trustee. In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and return it to the holder. Alternatively, if the Company or the Trustee so determines, the Issuers in exchange for the Note shall issue and the Trustee shall authenticate a new security that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 8.05. Trustee to Sign Amendments, etc.

The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 8 if the amendment, supplement or waiver does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment, supplement or waiver the Trustee shall be provided with and, subject to Section 7.01 hereof, shall be fully protected in relying upon an Officer’s Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture. Neither Issuer nor any Guarantor may sign an amendment or supplement until the Board of Directors of the general partner of the Company, the Board of Directors of Finance Co. or the Board of Directors or Board of Managers of such Guarantor, as appropriate, approves it.

ARTICLE 9

(ii) the following conditions are met:

(a) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption pursuant to paragraph 5 of the Notes and, in any case, the Issuers have irrevocably deposited or caused to be deposited with the Trustee as trust funds, in trust solely for the benefit of the holders of outstanding Notes, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire Debt (including all principal and accrued interest) on any Notes not theretofore delivered to the Trustee for cancellation,

(c) the Issuers have delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or on the date of redemption, as the case may be, and

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Issuers in Sections 7.07, 9.05 and 9.06 hereof shall survive such satisfaction and discharge.

Section 9.02. Legal Defeasance.

The Issuers may at their option, by Board Resolution, be discharged from their obligations with respect to the Notes and the Guarantors discharged from their obligations under the Guarantees on the date the conditions set forth in Section 9.04 below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Issuers shall be deemed to have paid and discharged the entire indebtedness represented by the Notes and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Issuers, shall, subject to Section 9.06 hereof, execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of holders of outstanding Notes to receive solely from the trust funds described in Section 9.04 hereof and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (B) the Issuers’ obligations with respect to the Notes under Sections 2.1 through 2.10 hereof, Section 2.13 hereof and Section 4.17 hereof, (C) the rights, powers, trusts, duties, and immunities of the Trustee and Collateral

-91-

and (D) this Article 9. If the Issuers exercises their Legal Defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect thereto and each Guarantor will be released from all of its obligations under its Guarantee.

Section 9.03. Covenant Defeasance.

At the option of the Company, pursuant to a Board Resolution, the Issuers and the Guarantors shall be released from (A) their respective obligations under Sections 4.02, 4.04 through 4.14, inclusive, 4.16 and 4.18 through 4.22, inclusive, (B) the operation of Sections 6.01(5), (6), (7) and (8) (only as such clauses (7) and (8) apply to Significant Subsidiaries), (9) and (10), and (C) the Company’s obligations under Section 5.01(a)(3) with respect to the outstanding Notes on and after the date the conditions set forth in Section 9.04 hereof are satisfied (hereinafter, “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that the Issuers and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section or portion thereof, whether directly or indirectly by reason of any reference elsewhere herein to any such specified section or portion thereof or by reason of any reference in any such specified Section or portion thereof to any other provision herein or in any other document, but the remainder of this Indenture and the Notes shall be unaffected thereby. If the Company exercises its Covenant Defeasance option, each Guarantor will be released from all its obligations under its Guarantee.

Section 9.04. Conditions to Defeasance or Covenant Defeasance.

The following shall be the conditions to application of Section 9.02 or Section 9.03 hereof to the outstanding Notes:

-92-

(3) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute default under any other agreement or instrument to which the Issuers is a party or by which it is bound;

(4) in the case of an election under Section 9.02 above, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling to the effect that or (ii) there has been a change in any applicable Federal income tax law with the effect that, and such opinion shall confirm that, the holders of the outstanding Notes or persons in their positions will not recognize income, gain or loss for Federal income tax purposes as a result of such Legal Defeasance and will be subject to Federal income tax on the same amounts, in the same manner, and at the same times as would have been the case if such Legal Defeasance had not occurred;

(5) in the case of an election under Section 9.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the holders of the outstanding Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such Covenant Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(6) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the Legal Defeasance under Section 9.02 above or the Covenant Defeasance under Section 9.03 hereof (as the case may be) have been complied with; and

Anything in this Article 9 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 9.04 hereof which, in the opinion of a nationally-recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

-93-

Section 9.06. Reinstatement.

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 9.01, 9.02 or 9.03 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ and each Guarantor’s obligations under this Indenture, the Notes and the Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article 9 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with Section 9.01 hereof; provided, however, that if the Issuers or the Guarantors have made any payment of principal of, premium, if any, or accrued interest on any Notes because of the reinstatement of their obligations, the Issuers or the Guarantors, as the case may be, shall be subrogated to the rights of the holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

Section 9.07. Moneys Held by Paying Agent.

In connection with the satisfaction and discharge of this Indenture, all moneys then held by any Paying Agent under the provisions of this Indenture shall, upon demand of the Company, be paid to the Trustee, or if sufficient moneys have been deposited pursuant to Section 9.01 hereof, to the Issuers (or, if such moneys had been deposited by the Guarantors, to such Guarantors), and thereupon such Paying Agent shall be released from all further liability with respect to such moneys.

Section 9.08. Moneys Held by Trustee.

Any moneys deposited with the Trustee or any Paying Agent or then held by the Issuers or the Guarantors in trust for the payment of the Accreted Value and principal of or premium, if any, or interest on any Note that are not applied but remain unclaimed by the holder of such Note for two years after the date upon which the Accreted Value and principal of, or premium, if any, or interest on such Note shall have respectively become due and payable shall be repaid to the Company (or, if appropriate, Finance Co. or the Guarantors) upon Company Request, or if such moneys are then held by the Issuers or the Guarantors in trust, such moneys shall be released from such trust; and the holder of such Note entitled to receive such payment shall thereafter, as an unsecured general creditor, look only to the Issuers and the Guarantors for the payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money shall thereupon cease; provided, however, that the Trustee or any such Paying Agent, before being required to make any such repayment, may, at the expense of the Company and the Guarantors, either mail to each holder affected, at the address shown in the register of the Notes maintained by the Registrar pursuant to Section 2.03 hereof, or cause to be published once a week for two successive weeks, in a newspaper published in the English language, customarily published each Business Day and of general circulation in The City of New York, New York, a notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such mailing or publication, any unclaimed balance of such moneys then remaining will be repaid to the Company. After payment to the Company, Finance Co. or the Guarantors or the release of any money held in trust by the Company, Finance Co. or any Guarantors, as the case may be, holders entitled to the money must look only to the Company and the Guarantors for payment as general creditors unless applicable abandoned property law designates another Person.

ARTICLE 10

GUARANTEE OF SECURITIES

Section 10.01. Guarantee.

Subject to the provisions of this Article 10, each Guarantor hereby jointly and severally unconditionally guarantees to each holder and to the Trustee, on behalf of the holders, (i) the due and punctual payment of the principal, and, premium, if any, and interest on the Notes, when and as the same shall become due and payable, whether at maturity, by acceleration or otherwise, the due and punctual payment of interest on the overdue principal of, and premium, if any, and interest on the Notes, to the extent lawful, and the due and punctual performance of all other Obligations of the Issuers to the holders or the Trustee all in accordance with the terms of this Indenture, and (ii) in the case of any extension of time of payment or renewal of the Notes or any of such other Obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, at stated maturity, by acceleration or otherwise. Each Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of any such Note or this Indenture, any failure to enforce the provisions of any such Note or this Indenture, any waiver, modification or indulgence granted to the Issuers with respect thereto by the holder of such Note or the Trustee, or any other circumstances which may otherwise constitute a legal or equitable discharge of a surety or such Guarantor.

Each Guarantor hereby waives diligence, presentment, filing of claims with a court in the event of merger or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest or notice with respect to any such Note or the Indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged as to any such Note except by payment in full of the principal thereof, premium if any, and interest thereon and as provided in Section 9.01 hereof. Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the holders and the Trustee, on the other hand, (i) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (ii) 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) shall forthwith become due and payable by each Guarantor for the purpose of this Guarantee. In addition, without limiting the foregoing provisions, upon the effectiveness of an acceleration under Article 6 hereof, the Trustee shall promptly make a demand for payment on all Obligations under the Guarantee provided for in this Article 10 and not discharged.

The Guarantee set forth in this Section 10.01 shall not be valid or become obligatory for any purpose with respect to a Note until the certificate of authentication on such Note shall have been signed by or on behalf of the Trustee.

Section 10.02. Execution and Delivery of Guarantees.

To evidence the Guarantee set forth in this Article 10, each Guarantor hereby agrees that a notation of such Guarantee may be placed on each Note authenticated and made available for delivery by the Trustee and that this Guarantee shall be executed on behalf of each Guarantor by the manual or facsimile signature of an Officer of each Guarantor.

Each Guarantor hereby agrees that the Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

-95-

If an Officer of a Guarantor whose signature is on the Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Guarantee is endorsed, the Guarantee shall be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of each Guarantor.

Section 10.03. Limitation of Guarantee.

The obligations of each Guarantor pursuant to Section 10.01 are limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee hereunder or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state or provincial law. Each Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a contribution from each other Guarantor and the Company in a pro rata amount based on the proportion that the net worth of the Company or the relevant Guarantor represents relative to the aggregate net worth of the Company and all of the Guarantors combined.

Section 10.04. Additional Guarantors.

Each of the Issuers covenants and agrees that it will cause any Person which becomes obligated to guarantee the Notes, pursuant to the terms of Section 4.12 hereof, to execute a supplemental indenture pursuant to which such Guarantor shall guarantee the obligations of the Company under this Indenture with respect to the Notes in accordance with this Article 10 with the same effect and to the same extent as if such Person had been named herein as a Guarantor.

Section 10.05. Release of Guarantor.

A Guarantor shall be released from all of its obligations under its Guarantee hereunder upon:

Notwithstanding the foregoing, upon designation of a Restricted Subsidiary as an Unrestricted Entity, such Restricted Subsidiary shall, by execution and delivery of a supplemental indenture, be released from any Guarantee previously made by such Restricted Subsidiary.

Section 10.06. Waiver of Subrogation.

Until this Indenture is discharged and all of the Notes are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Issuers that arise from the existence, payment, performance or enforcement of the Issuers’ obligations under the Notes or this Indenture and such Guarantor’s obligations under its Guarantee hereunder and this Indenture, in any such instance including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the holders against the Issuers, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuers, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Noteholders under the Notes, this Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Noteholders and shall forthwith be paid to the Trustee for the benefit of itself or such Noteholders to be credited and applied to the obligations in favor of the Trustee or the Noteholders, as the case may be, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 10.06 is knowingly made in contemplation of such benefits.

Section 11.03. Releases of Collateral.

The Liens securing the Notes and the Guarantees will, upon compliance with the conditions precedent to the release of the Collateral together with such documentation, if any, as may be required by the Trust Indenture Act, automatically and without the need for any further action by any Person be released so long as such release is otherwise in compliance with the TIA:

(a) in whole or in part, as applicable, as to all or any portion of property subject to such Liens which has been taken by eminent domain, condemnation or other similar circumstances, subject to the satisfaction of the conditions set forth in this Indenture or the Security Documents;

(b) in whole, as to all property subject to such Liens, upon;

-100-

transferred or disposed of or (b) is owned or at any time acquired by a Guarantor that has been released from its Guarantee, concurrently with the release of such Guarantee; or

(d) in part, as to property with the consent of the Trustee (with the vote of the holders of the Notes required under Section 8.02)

Notwithstanding anything to the contrary herein, the Issuers and the Guarantors will not be required to comply with all or any portion of Section 314(d) of the TIA if they determine, in good faith based on advice of counsel, that under the terms of that section and/or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of Section 314(d) of the TIA is inapplicable to the released Collateral. Without limiting the generality of the foregoing, certain no-action letters issued by the SEC have permitted an indenture qualified under the TIA to contain provisions permitting the release of collateral from Liens under such indenture in the ordinary course of the issuer’s business without requiring the issuer to provide certificates and other documents under Section 314(d) of the TIA.

Section 11.04. Authorization of Actions to Be Taken by the Collateral Agent Under the Security Documents.

The holders of Notes agree that the Collateral Agent and the Sub-Collateral Agent shall be entitled to the rights, privileges, protections, immunities, indemnities and benefits provided to the Collateral Agent and the Sub-Collateral Agent by the Security Documents. Furthermore, each holder of a Note, by accepting such Note, consents to the terms of and authorizes and directs the Trustee (in each of its capacities) and the Collateral Agent and the Sub-Collateral Agent to enter into and perform the Security Documents in each of its capacities thereunder.

Section 11.05. Authorization of Receipt of Funds by the Trustee Under the Security Agreement.

The Trustee is authorized to receive any funds for the benefit of holders distributed under the Security Documents to the Trustee, to apply such funds as provided in this Indenture and to make further distributions of such funds in accordance with the provisions of Section 6.10.

Section 11.06. Powers Exercisable by Receiver or Collateral Agent.

In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Issuers or any Guarantor, as applicable, with respect to the release, sale or other disposition of such Property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuers or any Guarantor, as applicable, or of any officer or officers thereof required by the provisions of this Article 11.

Section 12.05. When Treasury Notes Disregarded.

In determining whether the holders of the required aggregate principal amount or Accreted Value of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers, any Guarantor or any other obligor on the Notes or by any Affiliate of any of them shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Notes and that the pledgee is not an Issuer, a Guarantor or any other obligor upon the Notes or any Affiliate of any of them.

THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK. EACH OF THE PARTIES HERETO, AND THE HOLDERS BY THEIR ACCEPTANCE OF THE NOTES, AGREES TO SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE NOTES.

Section 12.09. No Adverse Interpretation of Other Agreements.

Each holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver and release may not be effective to waive liabilities under the U.S. Federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Section 12.11. Successors.

All agreements of the Issuers and the Guarantors in this Indenture, the Security Documents and the Notes shall bind their respective successors. All agreements of the Trustee, any additional trustee and any Paying Agents in this Indenture shall bind their successors.

Each provision of this Indenture shall be considered separable and if for any reason any provision which is not essential to the effectuation of the basic purpose of this Indenture or the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 12.15. Waiver of Jury Trial.

EACH OF THE ISSUERS, THE GUARANTORS, EACH HOLDER OF A NOTE BY ITS ACCEPTANCE THEREOF AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

Section 12.16. Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

Section 12.17. Currency of Account; Conversion of Currency; Foreign Exchange Restrictions.

(a) U.S. Dollars are the sole currency of account and payment for all sums payable by the Company and the Guarantors under or in connection with the Notes, the Guarantees of the Notes or this Indenture to the extent it relates to the Notes, including damages related thereto. Any amount received or recovered in a currency other than U.S. Dollars by a holder of Notes (whether as a result of, or of the enforcement of, a judgment or order of a court of any jurisdiction, in the winding-up or dissolution of the Issuers or otherwise) in respect of any sum expressed to be due to it from the Issuers shall only constitute a discharge to the Issuers to the extent of the U.S. Dollar amount, which the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so). If that U.S. Dollar amount is less than the U.S. Dollar amount expressed to be due to the recipient under the Notes, the Issuers and the Guarantors shall indemnify it against any loss sustained by it as a result as set forth in Section 12.17(b). In any event, the Company and the Guarantors shall indemnify the recipient against the cost of making any such purchase. For the purposes of this Section 12.17, it will be sufficient for the holder of a Note to certify in a satisfactory manner (indicating sources of information used) that it would have suffered a loss had an actual purchase of U.S. Dollars been made with the amount so received in that other currency on the date of receipt or recovery (or, if a purchase of U.S. Dollars on such date had not been practicable, on the first date on which it would have been practicable, it being required that the need for a change of date be certified in the manner

-105-

mentioned above). The indemnities set forth in this Section 12.17 constitute separate and independent obligations from other obligations of the Issuers and the Guarantors, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any holder of the Notes and shall continue in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under the Notes.

(b) The Issuers and the Guarantors, jointly and severally, covenant and agree that the following provisions shall apply to conversion of currency in the case of the Notes, the Guarantees and this Indenture:

(1)(A) If for the purpose of obtaining judgment in, or enforcing the judgment of, any court in any country, it becomes necessary to convert into a currency (the “Judgment Currency”) an amount due in any other currency (the “Base Currency”), then the conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which the judgment is given or the order of enforcement is made, as the case may be (unless a court shall otherwise determine).

(B) If there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Issuers and the Guarantors will pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the Judgment Currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Base Currency originally due.

(2) In the event of the winding-up of the Issuers or any Guarantor at any time while any amount or damages owing under the Notes, the Guarantees and this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Issuers and the Guarantors shall indemnify and hold the Noteholders and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (i) the date as of which the Applicable Currency Equivalent of the amount due or contingently due under the Notes, the Guarantees and this Indenture (other than under this subsection (b)(2)) is calculated for the purposes of such winding-up and (ii) the final date for the filing of proofs of claim in such winding-up. For the purpose of this subsection (b)(2), the final date for the filing of proofs of claim in the winding-up of the Issuers or any Guarantor shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of applicable law as being the latest practicable date as at which liabilities of the Issuers or such Guarantor may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto.

(c) The obligations contained in subsections (a), (b)(1)(B) and (b)(2) of this Section 12.17 shall constitute separate and independent obligations from the other obligations of the Issuers and the Guarantors under this Indenture, shall give rise to separate and independent causes of action against the Issuers and the Guarantors, shall apply irrespective of any waiver or extension granted by any Noteholder or the Trustee or either of them from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Issuers or any Guarantor for a liquidated sum in respect of amounts due hereunder (other than under subsection (b)(2) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Noteholders or the Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Issuers or any Guarantor or the liquidator or otherwise or any of them. In the case of subsection (b)(2) above, the amount of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution.

-106-

(d) The term “rate(s) of exchange” shall mean the rate of exchange quoted by Reuters at 10:00 a.m. (New York time) for spot purchases of the Base Currency with the Judgment Currency other than the Base Currency referred to in subsections (b)(1) and (b)(2) above and includes any premiums and costs of exchange payable.

Section 12.18. Agent for Service.

By the execution and delivery of this Indenture, each Canadian Guarantor (i) acknowledges that it has irrevocably designated and appointed CT Corporation System, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ (and any successor entity) as its authorized agent upon which process may be served in any suit or proceeding arising out of or relating to this Indenture, the Notes, the Guarantees and the Security Documents that may be instituted in any Federal or state court in the State of New York, The City of New York, the Borough of Manhattan or brought under Federal or state securities laws, and acknowledges that CT Corporation System has accepted such designation, (ii) irrevocably submits to the jurisdiction of any such court in any such suit or proceeding and (iii) agrees that service of process upon CT Corporation System and written notice of said service to the Canadian Guarantors in accordance with this Section 12.18 shall be deemed in every respect effective service of process upon the Canadian Guarantors, if any, in any such suit or proceeding. Each Canadian Guarantor further agrees to take any and all such action, including the execution and filing of any and all such documents and instruments as may be necessary to continue such designation and appointment of CT Corporation System in full force and effect so long as this Indenture shall be in full force and effect or any of the Notes shall be outstanding; provided, however, that any Canadian Guarantor may, by written notice to the Trustee, designate such additional or alternative agent for service of process under this Section 12.18 that (i) maintains an office located in the Borough of Manhattan, The City of New York, the State of New York, (ii) is a corporate service company which acts as agent for service of process for other Persons in the ordinary course of its business and (iii) agrees to act as agent for service of process in accordance with this Section 12.18. Such notice shall identify the name of such agent for process and the address of such agent for process in the Borough of Manhattan, The City of New York, the State of New York.

Section 12.19. Interest Act (Canada).

The Canadian Guarantors acknowledge that certain of the rates of interest applicable to their obligations may be computed on the basis of a year of 360 days or 365 days, as the case may be, and be paid for the actual number of days elapsed. For purposes of the Interest Act (Canada), whenever any interest is calculated using a rate based on a year of 360 days or 365 days, as the case may be, such rate determined pursuant to such calculation, when expressed as an annual rate, is equivalent to (i) the applicable rate based on a year of 360 days or 365 days, as the case may be, (ii) multiplied by the actual number of days in the calendar year in respect of which such interest is payable, and (iii) divided by 360 or 365, as the case may be.

Section 12.20. Joint and Several Obligations.

All of the obligations of the Issuers under the Notes shall be joint and several obligations of the Issuers.

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

[Insert the Restricted Notes Legend, if applicable pursuant to the provisions of the Indenture]

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

1. Interest. The Issuers jointly and severally promise to pay interest on the principal amount at maturity of this Note at the rate per annum shown above Until April 1, 2010, interest will accrue on the Notes at the rate of 14% per annum in the form of an increase in the Accreted Value (representing amortization of original issue discount) between the date of original issuance and April 1, 2010, on a semi-annual basis using a 360-day year comprised of twelve 30-day months, such that the Accreted Value shall be equal to the full principal amount at maturity of the notes on April 1, 2010 (the “Full Accretion Date”). Beginning on the Full Accretion Date, cash interest on the notes will accrue at the rate of 14% per annum and will be payable semiannually in arrears on April 1 and October 1 of each year. Cash interest on the Notes shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from and including April 1, 2010, until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Issuers shall pay interest on overdue principal at the rate borne by the Notes, and shall pay interest on overdue installments of interest at the same rate to the extent lawful.

2. Method of Payment. The Issuers shall pay interest on the Notes to the Persons who are registered holders at the close of business on the March 15 and September 15 next preceding the Interest Payment Date even if Notes are canceled after the record date and on or before the Interest Payment Date (whether or not a Business Day). The holders must surrender Notes to a Paying Agent to collect principal payments. The Issuers shall pay Accreted Value or principal, premium, if any, and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a Global Note (including Accreted Value or principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by DTC or any successor depositary. The Issuers will make all payments in respect of a certificated Note (including Accreted Value or principal, premium, if any, and interest), at the office of each Paying Agent, except that, at the option of the Issuers, payment of interest may be made by mailing a check to the registered address of each holder thereof; provided, however, that payments on the Notes may also be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such holder elects payment by wire transfer by giving written notice to the Trustee or a Paying Agent to such effect designating such account no later than 10 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent and Registrar. Initially, The Bank of New York, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any holder. Neither the Company nor any of its Subsidiaries or Affiliates may act as Paying Agent but they may act as Registrar or co-registrar.

4. Indenture; Guarantees; Security Documents; Restrictive Covenants. The Issuers issued the Notes under an Indenture dated as of March 30, 2006 (the “Indenture”), among the Company, Finance Co., the Guarantors and the Trustee. The Notes include any Additional Notes. The Notes and any Additional Notes are treated as a single class of securities under the Indenture. The terms of

A-3

this Note include those stated in the Indenture to be applicable by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) as in effect on the date of the Indenture. This Note is subject to all such terms, and the holder of this Note is referred to the Indenture for a statement of them. All capitalized terms in this Note, unless otherwise defined, have the meanings assigned to them by the Indenture.

The Indenture and Security Documents impose certain limitations on, among other things, indebtedness, issuance and sale of capital stock of Restricted Entities, restricted payments, liens, asset sales, transactions with affiliates, and restrictions on distributions from Restricted Entities.

The Notes are secured by the Liens created by the Security Documents, subject to the terms of such documents. The holder of this Note is referred to the Security Documents for a statement of such terms.

5. Optional Redemption.

Except as set forth below, the Issuers will not be entitled to redeem the Notes prior to April 1, 2010.

On and after April 1 2010, the Issuers are entitled to redeem all or, from time to time, a portion of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of Accreted Value on the redemption date), plus accrued interest, if any, to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on April 1 of the years set forth below:


Period	Redemption Price
2010	107.000	%
2011	103.500	%
2012 and thereafter	100.000	%

Prior to April 1, 2009, the Issuers are entitled on one or more occasions to redeem Notes (which includes Additional Notes, if any) in an aggregate principal amount at maturity not to exceed 35% of the originally issued aggregate principal amount at maturity of the Notes (including the principal amount at maturity of Additional Notes, if any) at a redemption price (expressed as a percentage of Accreted Value on the redemption date) of 114%, plus accrued and unpaid interest, if any, to (but excluding) the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), with the net cash proceeds from one or more Equity Offerings by the Company or, after the occurrence of a Parent Rollup Transaction, the Parent (to the extent the net proceeds thereof are contributed to the equity capital of the Company (other than in the form of Disqualified Stock) or are used to purchase Capital Stock of the Company (other than Disqualified Stock)); provided, however, that

(1) at least 65% of the originally issued aggregate principal amount at maturity of Notes (including the principal amount at maturity of Additional Notes, if any) remains outstanding immediately after the occurrence of each such redemption (other than Notes held, directly or indirectly, by the Issuers or its Affiliates); and

(2) each such redemption occurs within 180 days after the closing of the related Equity Offering.

A-4

At any time prior to April 1, 2010, we may also redeem all or a portion on one or more occasions of the Notes upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the Accreted Value of Notes redeemed plus the Applicable Premium (calculated as of a date no more than three Business Days prior to the relevant redemption notice) as of the date of redemption.

“Applicable Premium” means, with respect to any Note on any redemption date, the greater of:

(1) 1.0% of the Accreted Value of the Note; and

(2) if greater, the excess of:

(b) the Accreted Value of the Note.

6. No Mandatory Redemption. The Company shall not be required to make mandatory redemption payments with respect to the Notes.

7. Offers to Purchase. The Indenture requires that certain proceeds from Asset Dispositions or a Taking or Destruction be used, subject to further limitations contained therein, to make an offer to purchase certain amounts of Notes in accordance with the procedures set forth in the Indenture. The Company may also be required to make an offer to purchase Notes pursuant to Section 4.16 of the Indenture.

8. Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, in denominations of $2,000 and integral multiples of $2,000. A holder shall register the transfer or exchange of Notes in accordance with the Indenture. The Registrar may require a holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges in connection therewith as permitted by the Indenture. The Registrar need not register the transfer or exchange of any Notes during a period beginning 15 days before the mailing of a redemption notice for any Notes or portions thereof selected for redemption.

9. Persons Deemed Owners. The registered holder of this Note shall be treated as the owner of it for all purposes.

10. Unclaimed Money. If money for the payment of principal, premium or interest on any Note remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Company at its request. After that, holders entitled to money must look to the Company for payment as general creditors unless an “abandoned property” law designates another person.

11. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes may be modified, amended or supplemented by the Company, Finance Co., the Guarantors and the Trustee with the consent of the holders of at least

A-5

a majority in principal amount at maturity of the Notes then outstanding and any existing default or compliance with any provision may be waived in a particular instance with the consent of the holders of a majority in principal amount at maturity of the Notes then outstanding. Without the consent of holders, the Company, Finance Co., the Guarantors and the Trustee may amend the Indenture for certain specified purposes including providing for uncertificated Notes in addition to or in place of certificated Notes, and curing any ambiguity, omission, defect or inconsistency, or making any other change that does not materially adversely affect the rights, taken as a whole, of any holder.

12. Successor Entity. When a successor entity assumes all the obligations of its predecessors under the Notes, the Indenture and the Security Documents and immediately before and thereafter no Default exists and certain other conditions are satisfied, the predecessor entity will be released from those obligations.

13. Defaults and Remedies. Events of Default are set forth in the Indenture. If an Event of Default occurs and is continuing, the Trustee, by notice to the Issuers, or the holders of not less than 25% in aggregate principal amount at maturity of the Notes, by written notice to the Issuers and the Trustee, may declare to be immediately due and payable the Accreted Value of all the Notes then outstanding plus premium, if any, and accrued but unpaid interest to the date of acceleration and such amounts shall become immediately due and payable. In case an Event of Default specified in Section 6.01(7) or (8) with respect to either Issuer occurs, such Accreted Value, principal, premium, if any, and interest with respect to all of the Notes shall be due and payable immediately without any declaration or other act on the part of the Trustee or the holders of the Notes. After any such acceleration but before a judgment or decree based on acceleration is obtained by the Trustee, the holders of a majority in aggregate principal amount at maturity of outstanding Notes (by notice to the Trustee) may rescind and cancel such acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of accelerated Accreted Value, principal, premium, if any, or interest that has become due solely because of the acceleration, have been cured or waived, (ii) to the extent the payment of such interest is lawful, interest (at the same rate specified in the Notes) on overdue installments of interest and overdue Accreted Value, premium, if any, or interest, which has become due otherwise than by such declaration of acceleration, has been paid, (iii) the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee its expenses, disbursements and advances, (iv) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (v) in the event of the cure or waiver of a Default or Event of Default described in Section 6.01(7) or (8), the Trustee has received an Officer’s Certificate and an Opinion of Counsel that such Default or Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

14. Trustee Dealings with the Issuers. The Trustee under the Indenture and the Collateral Agent, in their individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuers, any Guarantor or their Affiliates, and may otherwise deal with the Issuers, any Guarantor or their Affiliates as if it were not Trustee or Collateral Agent, as the case may be.

15. No Recourse Against Others. No director, officer, employee, incorporator or partner of the Company, Finance Co., the Guarantors, the General Partner or Parent following a Parent Rollup Transaction or any of their respective Subsidiaries will have any liability for any obligations of the Issuers or any of their Subsidiaries under this Note or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. The holder of this Note by accepting this Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver and release may not be effective to waive liabilities under the U.S. Federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

A-6

16. Defeasance and Covenant Defeasance. The Indenture contains provisions for defeasance of the entire debt represented by the Notes and for defeasance of certain covenants in the Indenture upon compliance by the Company in each case with certain conditions set forth in the Indenture.

17. Abbreviations. Customary abbreviations may be used in the name of a holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

18. CUSIP Numbers. The Company has caused CUSIP Numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to holders of the Notes. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

19. Governing Law. THE INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE OR THE NOTES.

20. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

The Company will furnish to any holder upon written request and without charge a copy of the Indenture. Requests may be made to:
