Section 3.3. Offer to Purchase by Application of Balance in Net Available Cash

In the event that, pursuant to Section 4.6 hereof, the Company is required to commence an offer to all Holders of Notes (and to holders of other First-Priority Stock Secured Debt) to purchase Notes (and such other First-Priority Stock Secured Debt) (an “Asset Disposition Offer” ), it will follow the procedures specified below.

The Asset Disposition Offer shall be made to all Holders of Notes and all holders of other First-Priority Stock Secured Debt. The Asset Disposition Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “ Offer Period ”). No later than three Business Days after the termination of the Offer Period (the “ Purchase Date ”), the Company will apply the Net Available Cash available for the Asset Disposition Offer (the “Offer Amount” ) to the purchase of Notes and such other First-Priority Stock Secured Debt (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other First-Priority Stock Secured Debt tendered in response to the Asset Disposition Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

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

31

Upon the commencement of an Asset Disposition Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders and each of the holders of other First-Priority Stock Secured Debt, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such holders to tender Notes and other First-Priority Stock Secured Debt pursuant to the Asset Disposition Offer. The notice, which will govern the terms of the Asset Disposition Offer, will state:

(1) that the Asset Disposition Offer is being made pursuant to this Section 3.3 and Section 4.6 hereof and the length of time the Asset Disposition Offer will remain open;

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

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

(4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Disposition Offer will cease to accrue interest after the Purchase Date;

(5) that Holders electing to have a Note purchased pursuant to an Asset Disposition Offer may elect to have Notes purchased only in denominations of $2,000 and in integral multiples of $1,000 in excess thereof;

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

(7) that holders of Notes and other First-Priority Stock Secured Debt will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note or other First-Priority Stock Secured Debt the holder delivered for purchase and a statement that such holder is withdrawing his election to have such Note or other First-Priority Stock Secured Debt purchased;

(8) that, if the aggregate principal amount of Notes and other First-Priority Stock Secured Debt surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other First-Priority Stock Secured Debt to be purchased on a pro rata basis based on the principal amount of Notes and such other First-Priority Stock Secured Debt surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, will be purchased); and

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

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and other First-Priority Stock Secured Debt or portions thereof tendered pursuant to the Asset Disposition Offer, or if less than the Offer Amount has been tendered, all Notes and other First-Priority Stock Secured Debt tendered, and will

32

deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.3. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Disposition Offer on the Purchase Date.

Other than as specifically provided in this Section 3.3, any purchase pursuant to this Section 3.3 shall be made pursuant to the provisions of Article Eleven of the Existing Indenture.

Section 3.4. AHYDO Payments

If the Notes would otherwise constitute “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code, and if Section 163(e)(5) of the Code applies to the Notes, then at the end of each accrual period ending after the fifth anniversary of the issue date of such notes (the “ AHYDO Payment Date ”), the Company will be required to redeem for cash a portion of the principal of each such note equal to the amount necessary to avoid the application of Section 163(e)(5) of the Code. No payment pursuant to any other provisions of this Indenture will alter the Company’s obligation to make any such payment with respect to any Notes that remain outstanding on the AHYDO Payment Date.

(6) Liens created in substitution of or as replacements for any Liens permitted by clauses (1) to (5) set forth above, provided that the property encumbered by any substitute or replacement Lien is similar in nature and value to the property encumbered by the Lien that is being replaced, as determined in good faith by an officer of the Company; and

(7) Any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in the foregoing clauses (1) to (6) inclusive of any Debt secured thereby; provided that the principal amount of Debt secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement Lien shall be limited to all or part of the same property that secured the Lien extended, renewed or replaced (plus improvements on such property).

Section 4.2. Limitations on Sale and Lease-Back Transactions

The Company covenants and agrees that neither it nor any of its Subsidiaries will enter into any Sale and Lease-Back Transaction with another Person, other than the Company or any Guarantor, unless:

Section 4.3. Limitations on Issuances of Guarantees by Subsidiaries

The Company will not permit any of its Subsidiaries to Guarantee any Debt of the Company, unless at the time of and after giving effect to the issuance of such Guarantee, the aggregate amount of all such guaranteed Debt (including the aggregate principal amount of Notes and 9-Year Notes outstanding at such time) shall not exceed the greater of (x) $4.2 billion or (y) 5.0 times the aggregate amount of EBITDA for the most recent four consecutive fiscal quarters ending prior to the date of determination; provided that , unless the Notes are secured by substantially all the property and assets (other than accounts receivable and cash) of the Guarantors, the aggregate amount of all such Debt guaranteed by Guarantees that are not subordinated to the Guarantees of the Notes (including the aggregate principal amount of Notes and 9-Year Notes outstanding at such time) shall not exceed the greater of (a) $2.6 billion and (b) 3.0 times the aggregate amount of EBITDA for the most recent four consecutive fiscal quarters ending prior to the date of determination.

The form of such Note Guarantee is attached as Exhibit E hereto.

Section 4.5. SEC Reports

(1) all quarterly and annual reports that would be required to be filed with the Commission on Forms 10-Q and 10-K if the Company were required to file such reports; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports.

All such reports shall be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K shall include a report on the consolidated financial statements of the Company and its Consolidated Subsidiaries by the Company’s certified independent accountants.

Section 4.6. Asset Dispositions

The Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, consummate any Asset Disposition unless:

(1) the Company or such Subsidiary receives consideration at the time of such Asset Disposition at least equal to the fair market value, as determined in good faith by the Company, of the shares and assets subject to such Asset Disposition;

35

(2) at least 75% of the consideration received in such Asset Disposition by the Company or such Subsidiary is in the form of cash or cash equivalents;

(3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company or such Subsidiary, as the case may be:

(A) to the extent the Company elects (or is required by the terms of any Debt), to prepay, repay, redeem or purchase Senior Debt of the Company or of a Guarantor or Debt of a Subsidiary that is not a Guarantor (in each case other than Debt owed to the Company or one of its Subsidiaries) within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; or

(B) to the extent the Company elects, to acquire Additional Assets within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; and

(4) to the extent of the balance of such Net Available Cash after application in accordance with clauses (3)(A) or (3)(B) above, such balance is applied by the Company or such Subsidiary, as the case may be, to make an Asset Disposition Offer to the Holders of the Notes (and to holders of other First-Priority Stock Secured Debt) to purchase Notes (and such other First-Priority Stock Secured Debt) pursuant to and subject to the conditions contained in this Section and Section 3.3 hereof;

provided , however , that in connection with any prepayment, repayment or purchase of debt pursuant to clause (3)(A) or (4) above, the Company or such Subsidiary shall permanently retire such debt 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 , further , however , that, in the case of clause (3)(B) above, a binding commitment shall be treated as a permitted application of the Net Available Cash from the date of such commitment so long as the Company or such Subsidiary enters into such commitment with the good faith expectation that such Net Available Cash will be applied to satisfy such commitment within 180 days of such commitment (an “ acceptable commitment ”); provided , further that if any acceptable commitment is later canceled or terminated for any reason before such Net Available Cash is applied, then such Net Available Cash shall be applied pursuant to clause (4) above.

Notwithstanding the foregoing provisions of the preceding paragraph, the Company and such Subsidiaries will not be required to apply any Net Available Cash in accordance with the preceding paragraph except to the extent that the aggregate Net Available Cash from all Asset Dispositions subject to the preceding paragraph which is not applied in accordance with the preceding paragraph exceeds $100.0 million. Pending application of Net Available Cash pursuant to this Section 4.6, such Net Available Cash may be used in any other manner not prohibited by the Indenture.

For purposes of this Section 4.6, the following are deemed to be cash or cash equivalents:

(1) the assumption or discharge of debt or other liabilities of ours or any Subsidiary and the release of us or such Subsidiary from all liability on such debt or other liability in connection with such Asset Disposition;

(2) securities or other obligations received by us or any Subsidiary from the transferee that are converted by us or such Subsidiary into cash within 180 days of the Asset Disposition, to the extent of the cash received in that conversion; and

(3) Additional Assets.

36

In the event of an Asset Disposition that requires the purchase of Notes (and other First-Priority Stock Secured Debt), the Company will purchase Notes tendered pursuant to an Asset Disposition Offer by the Company for the Notes (and such other First-Priority Stock Secured Debt) at a purchase price of 100% of their principal amount (or, in the event such other First-Priority Stock Secured Debt was issued with significant original issue discount, 100% of the accreted value thereof), without premium, plus accrued but unpaid interest and Special Interest, if any (or, in respect of such other First-Priority Stock Secured Debt, such other price, not to exceed 100%, as may be provided for by the terms of such other First-Priority Stock Secured Debt), in accordance with the procedures (including prorating in the event of oversubscription) set forth in Section 3.3 hereof. If there remains a balance of Net Available Cash after purchasing all securities tendered, then such balance may be used in any manner not prohibited by the Indenture. If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their purchase, the Company will select the securities 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 or any greater integral multiple of $1,000 in excess thereof. The Company shall not be required to make such an Asset Disposition Offer to purchase Notes (and other First-Priority Stock Secured Debt) pursuant to this Section 4.6 if the Net Available Cash available therefor is less than $100.0 million (which lesser amount shall be carried forward for purposes of determining whether such an Asset Disposition Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an Asset Disposition Offer, Net Available Cash will be deemed to be reduced by the aggregate amount of such Asset Disposition Offer.

(1) that the Change of Control Offer is being made pursuant to this Section 4.7 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date of such Change of Control (the “Change of Control Payment Date” );

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

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

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.7, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.7 by virtue of such compliance.

(b) On the Change of Control Payment Date, the Company will:

(1) accept for payment all Notes or portions of Notes properly tendered and not validly withdrawn pursuant to the Change of Control Offer;

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

(3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

The Paying Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note issued for surrendered but unpurchased Notes will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

38

(d) Notwithstanding anything to contrary in this Section 4.7, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of the making of the Change of Control Offer.

(e) The Company may, with respect to the Notes, omit in any particular instance to comply with any term, provision or condition set forth in this Section 4.7, if before the time for such compliance the Holders of at least a majority in principal amount of the outstanding Notes shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or effect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. No supplemental indenture shall, without the consent of the Holder of each Outstanding Note affected thereby, modify any of the provisions of this Section 4.7(e), except to increase the percentage required to waive compliance by the Company of the covenants referenced here, provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section 4.7(e).

The additional First-Priority Stock Secured Debt will only be permitted to be secured by the Collateral if such Debt and the related Liens are permitted to be incurred under the Indenture, including Section 4.1 hereof.

The Collateral Trust Agreement sets forth the procedures pursuant to which an additional series of Debt can become an additional Series of First-Priority Stock Secured Debt that is entitled to be secured equally and ratably with the Notes by the Liens on the Collateral granted to the Collateral Trustee. The Indenture and all future First-Priority Stock Lien Documents will be required to provide that, notwithstanding (i) anything to the contrary contained in the Stock Lien Security Documents; (ii) the time of incurrence of any Series of First-Priority Stock Secured Debt; (iii) the order or method of attachment or perfection of any Liens securing any Series of First-Priority Stock Secured Debt; (iv) the time or order of filing or recording of financing statements or other documents filed or recorded to perfect any Lien upon any Collateral; (v) the time of taking possession or control over any Collateral; (vi) that any First-Priority Stock Lien may not have been perfected or may be or have become subordinated, by equitable subordination or otherwise, to any other Lien; or (vii) the rules for determining priority under any law governing relative priorities of Liens:

(1) all First-Priority Stock Liens granted at any time by the Company or any other Pledgor secure, equally and ratably, all present and future First-Priority Stock Secured Obligations; and

(2) all Proceeds of all First-Priority Stock Liens granted at any time by the Company or any other Pledgor will be allocated and distributed equally and ratably on account of the First-Priority Stock Secured Debt and other First-Priority Stock Secured Obligations.

The First-Priority Stock Lien Representative of each future Series of First-Priority Stock Secured Debt shall be required to deliver a Collateral Trust Joinder to the Collateral Trustee at the time of incurrence of such Series of First-Priority Stock Secured Debt, and the Company shall promptly provide the Trustee with a copy of each such Collateral Trust Joinder; provided, however , that the failure to so deliver a copy of such Collateral Trust Joinder to the Trustee shall not affect the status of such future Debt as First-Priority Stock Secured Debt if the other requirements contained in the Collateral Trust Agreement in connection with the incurrence of additional Secured Debt are complied with.

The Company may also incur new or additional Junior Stock Secured Debt in accordance with the provisions of the Indenture and the Collateral Trust Agreement.

ARTICLE NINE

NOTE GUARANTEES

Section 9.1. Guarantee

(a) Subject to this Article Nine, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the Obligations of the Company hereunder or thereunder, that:

(1) the principal of, premium and Special Interest, if any, and interest on, the Notes will be promptly paid in full when due, whether at Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other Obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

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

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

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby until payment in full of all Obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the Maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Five of the Existing Indenture (as amended hereby) for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such Obligations as provided in Article Five of the Existing Indenture (as amended

49

hereby), such Obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 9.2. Limitation on Guarantor Liability

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

Section 9.3. Execution and Delivery of Note Guarantee

To evidence its Note Guarantee set forth in Section 9.1 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Ninth Supplemental Indenture will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 9.1 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

If an Officer whose signature is on this Ninth Supplemental Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Ninth Supplemental Indenture on behalf of the Guarantors.

Section 9.4. Guarantors May Consolidate, Etc., Only on Certain Terms

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

Section 9.5. Releases

(a) Upon the full and final payment and performance of all Obligations under the Indenture and the Notes, each Guarantor will be released and relieved of any Obligations under its Note Guarantee.
