Subject to the provisions of this Section 2, each Subsidiary Guarantor hereby fully, unconditionally and irrevocably Guarantees, as primary obligor and not merely as surety, jointly and severally with each other Subsidiary Guarantor, to each Bondholder, to the extent lawful, and the Trustee the full and punctual payment when due, whether at final maturity, by acceleration, by redemption or otherwise, of the obligations of the Company under the Loan Agreement. Each Subsidiary Guarantor agrees that such Obligations will rank equally in right of payment with other Indebtedness of such Subsidiary Guarantor, except to the extent such other Indebtedness is subordinate to such Obligations. Each Subsidiary Guarantor further agrees (to the extent permitted by law) that such Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under hereunder notwithstanding any extension or renewal of any Obligation.

Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Bonds and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Bonds or the Obligations.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Bondholder to any security held for payment of the Obligations.

Except as set forth in Section 3, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Bonds in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or

15

otherwise affected by: (a) the failure of any Bondholder to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Guaranty, the Bonds or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Guaranty, the Bonds or any other agreement; (d) the release of any security held by any Bondholder; (e) the failure of any Bondholder to exercise any right or remedy against any other Subsidiary Guarantor; (f) any change in the ownership of the Company; (g) any default, failure or delay, willful or otherwise, in the performance of the Obligations; or (h) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor agrees that its Subsidiary Guarantee shall remain in full force and effect until payment in full of all Bonds or such Subsidiary Guarantor is released from its Subsidiary Guarantee as provided in Section 3. Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal or interest on any of the Bonds is rescinded or must otherwise be restored by any Bondholder upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Bondholder has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay any of the Bonds when and as the same shall become due, whether at final maturity, by acceleration, by redemption or otherwise, each Subsidiary Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee or the Trustee on behalf of the Bondholders an amount equal to the sum of (i) the unpaid amount of such Bonds then due and owing and (ii) accrued and unpaid interest on such Bonds then due and owing (but only to the extent not prohibited by law).

Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Bondholders, on the other hand, (x) the maturity of the Bonds Guaranteed hereby may be accelerated as provided in the Indenture, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Bonds Guaranteed hereby and (y) in the event of any such declaration of acceleration of such Bonds, such Bonds (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the purposes of this Guaranty.

Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee, or the Bondholders in enforcing any rights under this Guaranty.

16

Section 3. Limitation on Liability; Termination, Release and Discharge.

(a) Any term or provision of this Guaranty to the contrary notwithstanding, the obligations of each Subsidiary Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including any Guarantees under the Credit Facilities) and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the Obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution Obligations under this Guaranty, result in the Obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

(b) A Subsidiary Guarantor will be released from this Guaranty without the consent of the Authority, the Trustee or any Holders with no further notice or act of any party:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition as of the time of such disposition does not violate the covenant described in Section 3.5 of the Company Indenture (which is incorporated by reference in Section 5.17 of the Loan Agreement);

(2) in connection with any sale or other disposition of such amount of Capital Stock of that Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if such sale or other disposition does not violate the covenant described in Section 3.5 of the Company Indenture (which is incorporated by reference in Section 5.17 of the Loan Agreement) and the Subsidiary Guarantor ceases to be a Restricted Subsidiary of the Company as a result thereof;

(3) if the Company designates that Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the provisions of the Agreement or (ii) if such Subsidiary Guarantor becomes an Excluded Subsidiary;

(4) upon defeasance of the Bonds in accordance with the Indenture;

(5) at such time as such Subsidiary Guarantor becomes an Immaterial Subsidiary of the Company; or

(6) as provided in the covenant described below in Section 7 hereof.

Any released Subsidiary Guarantor will join this Guaranty if required to do so pursuant to Section 7.

17

Section 4. Right of Contribution.

Each Subsidiary Guarantor hereby agrees that to the extent that any Subsidiary Guarantor shall have paid more than its proportionate share of any payment made on the Obligations under the Subsidiary Guarantees, such Subsidiary Guarantor shall be entitled to seek and receive contribution from and against the Company or any other Subsidiary Guarantor who has not paid its proportionate share of such payment, based on the respective net assets of all the Subsidiary Guarantors at the time of such payment, determined in accordance with GAAP. The provisions of this Section 4 shall in no respect limit the obligations and liabilities of each Subsidiary Guarantor to the Trustee and the Bondholders, and each Subsidiary Guarantor shall remain liable to the Trustee and the Bondholders for the full amount Guaranteed by such Subsidiary Guarantor hereunder.

Section 5. No Subrogation. Notwithstanding any payment or payments made by each Subsidiary Guarantor hereunder, no Subsidiary Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Bondholder against the Company or any other Subsidiary Guarantor or Guarantee or right of offset held by the Trustee or any Bondholder for the payment of the Obligations, nor shall any Subsidiary Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Subsidiary Guarantor in respect of payments made by such Subsidiary Guarantor hereunder, until all amounts owing to the Trustee and the Bondholders by the Company on account of the Bonds are paid in full. If any amount shall be paid to any Subsidiary Guarantor on account of such subrogation rights at any time when all of the Bonds shall not have been paid in full, such amount shall be held by such Subsidiary Guarantor in trust for the Trustee and the Bondholders, segregated from other funds of such Subsidiary Guarantor, and shall, forthwith upon receipt by such Subsidiary Guarantor, be turned over to the Trustee in the exact form received by such Subsidiary Guarantor (duly indorsed by such Subsidiary Guarantor to the Trustee, if required), to be applied against the Obligations.

Section 6. Successor Subsidiary Guarantors. A Subsidiary Guarantor may consolidate with, merge with or into, or transfer all or substantially all of its assets to any other Person to the extent described in Section 5.2 of the Loan Agreement provided, that if such Person (the “Successor Subsidiary Guarantor”) is not the Company or another Subsidiary Guarantor, the Subsidiary Guarantor’s obligations under this Guaranty and all other Bond Documents to which such Subsidiary Guarantor is party and its Subsidiary Guarantee must be expressly assumed by such other Person pursuant to agreements or instruments satisfactory to the Trustee, unless such Subsidiary Guarantee is released as described in Section 3(b) hereof. The Successor Subsidiary Guarantor, if applicable, shall be a Restricted Subsidiary and shall take such action (or agree to take such action) as may be reasonably necessary to cause any property or assets that constitute Collateral owned by or transferred to the Successor Subsidiary Guarantor to be subject to the Parity Liens in the manner and to the extent required under the Bond Documents and shall deliver an opinion of counsel as to the enforceability of any amendments, supplements or other instruments with respect to the Bond Documents to be executed, delivered, filed and recorded, as applicable, and such other matters as the Trustee or Collateral Trustee, as applicable, may reasonably request.

18

Section 7. Future Subsidiary Guarantors. The Subsidiaries of the Company that Guarantee or are required to guarantee the Company’s Obligations under the Senior Credit Facility, will become Subsidiary Guarantors by executing one or more joinders to this Guaranty substantially in the form of Exhibit A hereto (a “Joinder”) and delivering them to the Trustee. If any Domestic Subsidiary of the Company that is not an Immaterial Subsidiary and that is not already a Subsidiary Guarantor Guarantees or otherwise becomes an obligor with respect to any other Indebtedness of the Company or any Subsidiary Guarantor in excess of the De Minimis Amount, then such Domestic Subsidiary will become a Subsidiary Guarantor by executing a Joinder and delivering it to the Trustee within 20 Business Days of the date on which it Guaranteed or became an obligor with respect to such Indebtedness; provided, however, that the preceding shall not apply to Subsidiaries of the Company that have properly been designated as Unrestricted Subsidiaries in accordance with Section 3.15 of the Company Indenture (incorporated by reference in Section 5.17 of the Loan Agreement) for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Subsidiary Guarantee of a Domestic Subsidiary that was incurred pursuant to this section shall provide by its terms that it shall be automatically and unconditionally released at such time as such Subsidiary Guarantor ceases to Guarantee or otherwise be an obligor with respect to any other Indebtedness of the Company or any other Subsidiary Guarantor in excess of the De Minimis Amount.

The Obligations of each Subsidiary Guarantor shall be limited in accordance with the provisions of this Guaranty as described in Section 3.

Each Subsidiary Guarantor shall be released in accordance with the provisions of this Guaranty described in Section 3.

Section 8. Security Documents.

(a) The due and punctual payment of the Bonds hereunder, when and as the same shall be due and payable, whether on an interest payment date, at Stated Maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and interest (to the extent permitted by law), if any, on the Bonds and any Subsidiary Guarantee and performance of all other Obligations of any of the Company and any Subsidiary Guarantor to the Bondholders or the Trustee under the Loan Agreement according to the terms hereunder or thereunder (collectively, the “Secured Obligations”), will be secured by second-priority Liens on the Collateral granted to the Collateral Trustee for the benefit of the Bonds, the Company Notes and future other Parity Lien Obligations. Except as otherwise provided in the Intercreditor Agreement, the Collateral includes all of the assets of the Company and the Subsidiary Guarantors that are subject to a Lien securing Priority Lien Obligations (as defined in the Company Indenture), other than cash collateral to (i) issuers of letters of credit pursuant to the Priority Lien Documents rather than holders of all Priority Lien Obligations or (ii) with respect to any letters of credit issued pursuant to the Priority Lien Documents, to the Priority Lien Agent for the benefit of the holders of Priority Lien Obligations as a whole. For all purposes of this Guaranty, all references to “second-priority” Liens means Liens that may be junior in priority to the Liens securing Priority Lien Obligations, to the extent permitted to be incurred or to exist under the Intercreditor Agreement, and to Permitted Prior Liens. These second-priority Liens will also be senior in priority to the Liens securing Junior Lien Obligations, to the extent permitted to be incurred or to exist under the Bond Documents (as defined in the Loan Agreement).

19

(b) The Collateral and the Liens remain at all times subject to the terms of the Note Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral and authorizing the Collateral Trustee to enter into any Security Document on its behalf) as the same may be in effect or may be amended from time to time in accordance with its terms and to the rights of the Collateral Trustee subject to the Intercreditor Agreement to perform its obligations and exercise its rights under the Security Documents.

(c) Each Holder (as defined in the Company Indenture), by accepting a Bond, shall be deemed (i) to have agreed to be bound by the terms of the Security Documents and (ii) to appoint the Collateral Trustee or the Trustee, as the case may be, as its agent under the Security Documents and the Intercreditor Agreement and to authorize it to act as such.

(d) The Collateral Trustee is hereby authorized to exercise such rights, powers and discretions as are specifically delegated to it by the terms of the Security Documents, including the power to enter into the Security Documents, on behalf of the Bondholders, together with all rights, powers and discretions as are reasonably incidental thereto or necessary to give effect to the trusts created thereunder in accordance with the terms thereof.

(e) Notwithstanding any other provision of this Guaranty or any other Note Document, neither the Trustee nor the Collateral Trustee shall have any responsibility for the validity, perfection, sufficiency, adequacy, priority or enforceability of any Lien or Security Document or other security interest, or shall have any obligation to take any action to procure or maintain such validity, perfection, sufficiency, adequacy, priority or enforceability, including without limitation no responsibility to make any filings to perfect or maintain the perfection of the Collateral Trustee’s security interest in the Collateral.

Section 9. Release of Collateral. Collateral or any portion thereof may be released from the Parity Liens and security interests created by the Note Documents and the Loan Agreement at any time or from time to time in accordance with the provisions of the Security Documents, the Intercreditor Agreement and this Guaranty without the consent of the Authority or the Trustee. Notwithstanding anything to the contrary in the relevant Security Documents and the Intercreditor Agreement, upon receipt by the Collateral Trustee of a certificate that complies with Section 12, the Collateral Trustee is authorized to release the Collateral as security for the Bonds and, upon any such release, the right of the Holders to the benefit of the Collateral Trustee’s second priority Liens on and security interest in the Collateral will terminate and be discharged. Upon receipt of such certificate and request by the Company, the Collateral Trustee shall execute, deliver or acknowledge any instruments of termination, satisfaction or release, without recourse or warranty, to evidence the release of any such Collateral, all at the sole cost and expense of the Company and the Subsidiary Guarantors.

Section 10. Authorization of Actions to be Taken by the Trustee. Subject to the terms of the Security Documents and the Intercreditor Agreement (including any consent of the Holders required thereunder), the Trustee may, in its sole discretion, direct, on behalf of the Holders of the Bonds, the Collateral Trustee to take all actions it deems necessary or appropriate in order to:

(a) enforce any of the terms of the Security Documents and the Intercreditor Agreement; and

20

(b) collect and receive any and all amounts payable in respect of the Obligations of the Company or any Subsidiary Guarantors under this Guaranty.

Subject to the Collateral Trust Agreement, the Intercreditor Agreement and the Security Documents, the Trustee will have power to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or in violation of the Security Documents, the Intercreditor Agreement or this Guaranty, and such suits and proceedings as the Trustee may deem expedient to preserve or protect its interests and the interests of the Holders of the Bonds in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest under this Guaranty or be prejudicial to the interests of the Holders of the Bonds or of the Trustee).

Section 11. Authorization of Receipt of Funds by the Trustee. The Trustee is authorized to receive any funds for the benefit of the Bondholders distributed under the Indenture and Loan Agreement, and to make further distributions of such funds to the Bondholders according to the provisions of this Guaranty, the Indenture and the Loan Agreement.

Section 12. Termination of Security Interest. The Collateral, or any portion thereof, shall be released from the Lien and security interest created by the Security Documents, all without delivery of any instrument or performance of any act by any party, and without consent of the Authority or the Trustee, at any time or from time to time in accordance with the provisions of the Security Documents (including upon the release of a Subsidiary Guarantor as provided in Section 3. Upon such release, all rights in the Collateral so released shall revert to the Company or the applicable Subsidiary Guarantor. Without limiting the generality of the foregoing, the Collateral shall be released from the Liens, or such Liens shall no longer secure the Bonds, under one or more of the following circumstances:

(a) upon satisfaction and discharge of the Loan Agreement and Indenture;

(b) upon Legal Defeasance of the Bonds;

(c) upon payment in full in cash and discharge of all Bonds outstanding under the Indenture and all other Obligations that are outstanding, due and payable under this Guaranty at the time the Bonds are paid in full in cash and discharged;

(d) as to any Collateral of the Company or a Subsidiary Guarantor that becomes an Excluded Subsidiary, is sold, transferred or otherwise disposed of by the Company or any Subsidiary Guarantor to a Person that is not (either before or after such sale, transfer or disposition) the Company or a Restricted Subsidiary of the Company in a transaction or other circumstance that does not violate Section 3.5 of the Company Indenture ((which is incorporated by reference in Section 5.17 of the Loan Agreement) other than the obligation to apply proceeds of such Asset Disposition as provided therein) and is permitted (or not prohibited) by the Note Documents, at

21

the time of such sale, transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of (including a release of the Receivables or related contracts giving rise to Receivables from time to time in connection with a Qualified Receivables Transaction); provided that the Collateral Trustee’s Liens upon the Collateral will not be released if the sale or disposition is subject to Section 6 hereof;

(e) in whole or in part, with the consent of the Holders of the requisite percentage of the Bonds and Holders of the Company Notes in accordance with the provisions set forth in Article IX of the Company Indenture;

(f) with respect to the assets of any Subsidiary Guarantor, at the time such Subsidiary Guarantor is released from its Subsidiary Guarantee pursuant to the terms hereof; or

(g) if and to the extent required by the provisions of the Collateral Trust Agreement or the provisions of the Intercreditor Agreement.

The Collateral Trustee and the Trustee (to the extent required or necessary) upon receipt of an Officers’ Certificate and Opinion of Counsel will take all necessary action required to effectuate any release of Collateral (or any assets and property constituting Excluded Assets as defined in the Credit Agreement), as requested by and at the cost and expense of the Company, in accordance with the provisions of this Guaranty, the Intercreditor Agreement and the relevant Security Document.

Section 13. Further Action.

(a) Upon the terms and subject to the conditions of this Guaranty and the Security Documents, each Subsidiary Guarantor shall use its reasonable efforts to take, or cause to be taken, all appropriate action, and to do or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the security over the Collateral as contemplated by the Security Documents and the Intercreditor Agreement, including, without limitation, (i) preparing or causing to be prepared any required filings under the Security Documents and the Intercreditor Agreement, (ii) using reasonable efforts to make all required filings, notifications, releases and applications and to obtain licenses, permits, consents, approvals, authorizations, qualifications and orders of governmental authorities and parties to contracts with the Subsidiary Guarantor as are necessary for the grants of security contemplated by this Guaranty and the Security Documents and to fulfill the conditions of the Security Documents including, without limitation, delivery of title deeds and all other documents of title relating to the Collateral secured by the Security Documents in the manner as provided for therein and in the Intercreditor Agreement to which any Subsidiary Guarantor is a party, (iii) taking any and all action to perfect the security over the Collateral as contemplated by this Guaranty and the Security Documents, (iv) cooperating in all respects with each other in connection with any investigation or other inquiry, including any proceeding initiated by any Person, in connection with the granting of security over the Collateral, (v) keeping the Trustee or Collateral Trustee informed in all material respects of any material communication received by any Subsidiary Guarantor from, or given by them to, any governmental authority or any other Person regarding any matters contemplated by the Security Documents and the Intercreditor Agreement or with respect to the Collateral, (vi) permitting the Trustee or Collateral Trustee to review any material communication given by the Company or any

22

Subsidiary Guarantor to any such governmental authority or any other Person and (vii) in connection with any merger, consolidation or sale of assets of any Subsidiary Guarantor, to treat property and assets of the Person which is consolidated or merged with any Subsidiary Guarantor, to the extent that they are property or assets of the type which would constitute Collateral under the Security Documents, as after-acquired property and to take such actions as may be reasonably necessary to cause such property and assets to be made subject to the Parity Liens, in the manner and to the extent required under the Security Documents.

(b) Upon the reasonable request of the Collateral Trustee or any Parity Lien Representative at any time, each of the Subsidiary Guarantors will promptly execute, acknowledge and deliver such Security Documents, instruments, certificates, notices and other documents, and take such other actions as shall be reasonably required, or that the Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Parity Lien Documents for the benefit of the holders of Parity Lien Obligations; provided that no such Security Document, instrument or other document shall be materially more burdensome upon the Subsidiary Guarantors than the Parity Lien Documents executed and delivered by the Subsidiary Guarantors (it being understood that the Collateral Trustee shall have no liability whatsoever to determine whether such a document is materially burdensome and shall have no liability whatsoever with respect to this determination).

(c) If the Subsidiary Guarantor acquires any property or asset, and any Priority Lien Document or Junior Lien Document, as applicable, requires any supplemental Security Document for such collateral or other actions to achieve a perfected Lien on such collateral, then the Subsidiary Guarantor shall, promptly (but in no event later than the date that is ten (10) Business Days after the date which supplemental security documents are executed and delivered (or other action taken) under the Priority Lien Documents or Junior Lien Documents, as applicable), to the extent permitted by applicable law, execute and deliver to the Collateral Trustee appropriate Security Documents (or amendments thereto) in such form as shall be necessary to grant the Collateral Trustee a perfected second-priority Lien on such Collateral or take such other actions in favor of the Collateral Trustee as shall be necessary to grant a perfected Lien on such collateral to the Collateral Trustee, subject to the terms of Parity Lien Documents. Additionally, subject to the Parity Lien Documents, if any Subsidiary Guarantor creates any additional Lien upon any property or asset that would constitute Collateral, or takes any additional actions to perfect any existing Lien on Collateral, in each case for the benefit of the holders of the Priority Lien Debt or the holders of Junior Lien Debt, such Subsidiary Guarantor, must, to the extent permitted by applicable law, within ten (10) Business Days after the date such Lien is granted or such other action is taken, grant a second-priority Lien upon such property or asset, or take such additional perfection actions, as applicable, for the benefit of the Parity Lien Secured Parties and obtain all related deliverables as those delivered to the Priority Lien Agent or Junior Lien Collateral Trustee, as applicable, in each case as security for the obligations of the Subsidiary Guarantors with respect to the Parity Lien Obligations.

Notwithstanding the foregoing, to the extent that any Lien on any Collateral is perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the Priority Lien Agent, or of agents or bailees of the Priority Lien Agent, the perfection actions and related deliverables described in this paragraph shall not be required.
