Guarantee

Section 2.01. Guarantee. Each Guarantor unconditionally and irrevocably guarantees, jointly with the other Guarantors and severally, to the Administrative Agent, for the ratable benefit of the Secured Parties, as a primary obligor and not merely as a surety, the due and punctual payment and performance of its Guaranteed Obligations. Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its guarantee notwithstanding any extension or renewal of any Guaranteed Obligation. Each Guarantor waives presentment to, demand of payment from and protest to the Borrower or any other Loan Party of any of the Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment.

Section 2.02. Guarantee of Payment. Each Guarantor further agrees that its guarantee hereunder constitutes a guarantee of payment when due (whether at the stated maturity, by acceleration or otherwise) and not of collection, and waives any right to require that any resort be had by the Administrative Agent or any other Secured Party to any security held for the payment of the Guaranteed Obligations or to any balance of any deposit account or credit on the books of the Administrative Agent or any other Secured Party in favor of the Borrower or any other person.

3

Section 2.03. No Limitations, Etc. (a) Except for termination or release of a Guarantor’s obligations hereunder as expressly provided for in Section 4.11 and except for the limitations set forth in Section 2.07 or, with respect to any Subsidiary Loan Party that becomes a party hereto pursuant to Section 4.12 or otherwise, in any Supplement to this Agreement, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise (other than defense of payment or performance). Without limiting the generality of the foregoing, the obligations of each Guarantor hereunder, to the fullest extent permitted by applicable law, shall not be discharged or impaired or otherwise affected by, and each Guarantor hereby waives any defense to the enforcement hereof by reason of:

(i) the failure of the Administrative Agent or any other Secured Party to assert any claim or demand or to exercise or enforce any right or remedy under the provisions of any Loan Document or otherwise;

(ii) any rescission, waiver, amendment or modification of, increase in the Guaranteed Obligations with respect to, or any release from any of the terms or provisions of, any Loan Document or any other agreement, including with respect to any other Guarantor under this Agreement;

(iii) the failure to perfect any security interest in, or the exchange, substitution, release or any impairment of, any security held by the Administrative Agent or any other Secured Party for the Guaranteed Obligations;

(iv) any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations;

(v) any other act or omission that may or might in any manner or to any extent vary the risk of any Guarantor or otherwise operate as a discharge of any Guarantor as a matter of law or equity (other than the payment in full in cash or immediately available funds of all the Guaranteed Obligations);

(vi) any illegality, lack of validity or enforceability of any Guaranteed Obligation or the Credit Agreement or any other Loan Document or any Ancillary Agreement;

(vii) any change in the corporate existence, structure or ownership of any Loan Party, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting a Loan Party or its assets or any resulting release or discharge of any Guaranteed Obligation;

4

(viii) the existence of any claim, set-off or other rights that a Guarantor may have at any time against the Borrower, the Administrative Agent, or any other corporation or person, whether in connection herewith or any unrelated transactions, provided that nothing herein will prevent the assertion of any such claim by separate suit or compulsory counterclaim;

(ix) any action permitted or authorized hereunder; or

(x)(A) any other circumstance (including, without limitation, any statute of limitations, law, regulation, decree or order of any jurisdiction) or (B) any existence of or reliance on any representation by the Administrative Agent, in each case, that might otherwise constitute a defense to, or a legal or equitable discharge of, the Borrower or any Guarantor for its Guaranteed Obligations or any other guarantor or surety.

Each Guarantor expressly authorizes the Secured Parties to take and hold security for the payment and performance of the Guaranteed Obligations, to exchange, waive or release any or all such security (with or without consideration), to enforce or apply such security and direct the order and manner of any sale thereof in their sole discretion or to release or substitute any one or more other guarantors or obligors upon or in respect of the Guaranteed Obligations, all without affecting the obligations of any Guarantor hereunder.

(b) To the fullest extent permitted by applicable law, each Guarantor waives diligence, promptness, presentment, protest and notice of protest, demand for payment or performance, notice of default or nonpayment, notice of acceptance and any other notice with respect to the Guaranteed Obligations or any part of them to or upon the Borrower or any Guarantor with respect to the Guaranteed Obligations, any defense based on or arising out of disability or any defense of any other Loan Party or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any other Loan Party, other than the payment in full in cash or immediately available funds of all the Guaranteed Obligations (other than contingent or unliquidated obligations or liabilities). The Administrative Agent and the other Secured Parties may, at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales, accept an assignment of any such security in lieu of foreclosure, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with any other Loan Party or exercise any other right or remedy available to them against any other Loan Party, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Guaranteed Obligations (other than contingent or unliquidated obligations or liabilities) have been paid in full in cash or immediately available funds. To the fullest extent permitted by applicable law, each Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against any other Loan Party, as the case may be, or any security.

5

(c) Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Guaranteed Obligations made by the Administrative Agent or any Secured Party may be rescinded by the Administrative Agent or such Secured Party and any of the Guaranteed Obligations continued, and the Guaranteed Obligations, or the liability of any other person upon or for any part thereof, or any Collateral or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any Secured Party, and the Credit Agreement and the other Loan Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders or all Lenders, as the case may be) may deem advisable from time to time, and any Collateral, guarantee or right of offset at any time held by the Administrative Agent or any Secured Party for the payment of the Guaranteed Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Guaranteed Obligations or for the guarantee contained in this Section 2.03 or any property subject thereto.

Section 2.04. Reinstatement. Each Guarantor agrees that its guarantee hereunder shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Guaranteed Obligation is rescinded or must otherwise be restored by the Administrative Agent or any other Secured Party upon the bankruptcy or reorganization of the Borrower or any other Loan Party, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or any Loan Party or any substantial part of its property, or otherwise.

Section 2.05. Agreement to Pay; Contribution; Subrogation. In furtherance of the foregoing and not in limitation of any other right that the Administrative Agent or any other Secured Party has at law or in equity against any Guarantor by virtue hereof, but subject to the limitations set forth in Section 2.07, upon the failure of the Borrower or any other Loan Party to pay any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each Guarantor hereby promises to and will forthwith pay, or cause to be paid, to the Administrative Agent for distribution to the applicable Secured Parties in cash the amount of such unpaid Guaranteed Obligation. Subject to the limitations set forth in Section 2.07, each Guarantor hereby unconditionally and irrevocably agrees that in the event any payment shall be required to be made to any Secured Party under this Agreement, such Guarantor will contribute in respect of its Guaranteed Obligations, to the maximum extent permitted by law, such amounts to each other Guarantor so as to maximize the aggregate amount paid to the Secured Parties under or in respect of the Loan Documents. Upon payment by any Guarantor of any sums to the Administrative Agent as provided above or upon enforcement of any Security Documents granted by any Guarantor, all rights of such Guarantor against the applicable Borrower or any other Guarantor arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall in all respects be subject to Article III.

6

Section 2.06. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of the financial condition and assets of the Borrower and each other Loan Party, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Administrative Agent or the other Secured Parties will have any duty to advise such Guarantor of information known to it or any of them regarding such circumstances or risks.

Section 2.07. Maximum Liability. Each Guarantor, and by its acceptance of this Agreement, the Administrative Agent and each Secured Party hereby confirms that it is the intention of all such Persons that this Agreement and the Guaranteed Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code or any other federal or state bankruptcy, insolvency, receivership or similar law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to this Agreement and the Guaranteed Obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent, the Secured Parties and the Guarantors hereby irrevocably agree that the Obligations of each Guarantor under this Agreement at any time shall be limited to the maximum amount as will result in the Guaranteed Obligations of such Guarantor under this Agreement not constituting a fraudulent transfer or conveyance.

Section 2.08. Payment Free and Clear of Taxes. Any and all payments by or on account of any obligation of any Guarantor hereunder or under any other Loan Document shall be made free and clear of, and without deduction for, any Indemnified Taxes or Other Taxes on the same terms and to the same extent that payments by the Borrower are required to be made pursuant to the terms of Section 2.17 of the Credit Agreement. The provisions of Section 2.17 of the Credit Agreement shall apply to each Guarantor mutatis mutandis.

Section 2.09. Additional Borrowers or Subsidiary Parties. The guarantee of any Subsidiary Loan Party that becomes a party hereto pursuant to Section 4.12 shall be subject to the limitations (if any) set forth in the applicable Supplement relating to such guarantee.

ARTICLE III

Indemnity, Subrogation and Subordination

Section 3.01. Indemnity. In addition to all such rights of indemnity and subrogation as the Guarantors may have under applicable law (but subject to Section 3.03 hereof), the Borrower agrees that (a) in the event a payment shall be made by any

7

Guarantor (including another Borrower, in its capacity as a Guarantor hereunder) under this Agreement in respect of any Guaranteed Obligation of the Borrower, the Borrower shall indemnify such Guarantor for the full amount of such payment and such Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment and (b) in the event any assets of any Guarantor shall be sold pursuant to a Security Document to satisfy in whole or in part a Guaranteed Obligation owed to any Secured Party by the Borrower, the Borrower shall indemnify such Guarantor in an amount equal to the greater of the book value or the fair market value of the assets so sold.

Section 3.02. Contribution and Subrogation. Each Guarantor (a “Contributing Guarantor”) agrees (subject to Section 3.03 hereof) that, in the event a payment shall be made by any other Guarantor hereunder in respect of any Guaranteed Obligation, or assets of any other Guarantor shall be sold pursuant to any Security Document to satisfy any Guaranteed Obligation owed to any Secured Party and such other Guarantor (the “Claiming Guarantor”) shall not have been fully indemnified by the Borrower as provided in Section 3.01 hereof, the Contributing Guarantor shall indemnify the Claiming Guarantor in an amount equal to the amount of such payment or the greater of the book value or the fair market value of such assets, as applicable, in each case multiplied by a fraction of which the numerator shall be the net worth of such Contributing Guarantor on the date hereof and the denominator shall be the aggregate net worth of all the Guarantors on the date hereof (or, in the case of any Guarantor becoming a party hereto pursuant to Section 4.12 hereof, the date of the supplement hereto executed and delivered by such Guarantor). Any Contributing Guarantor making any payment to a Claiming Guarantor pursuant to this Section 3.02 shall be subrogated to the rights of such Claiming Guarantor under Section 3.01 hereof to the extent of such payment.

Section 3.03. Subordination; Subrogation. (a) Subject to the limitations set forth in Section 2.07, to the extent permitted by law and to the extent to do so would not constitute unlawful financial assistance, each Guarantor hereby subordinates any and all debts, liabilities and other Obligations owed to such Guarantor by each other Loan Party (the “Subordinated Obligations”) to the Guaranteed Obligations to the extent and in the manner hereinafter set forth in this Section 3.03:

(i) Prohibited Payments, Etc. Each Guarantor may receive payments from any other Loan Party on account of the Subordinated Obligations. After the occurrence and during the continuance of any Event of Default, if requested by the Administrative Agent or required by the Required Lenders, no Guarantor shall demand, accept or take any action to collect any payment on account of the Subordinated Obligations until the Guaranteed Obligations have been irrevocably paid in full in cash.

(ii) Prior Payment of Guaranteed Obligations. In any proceeding under the Bankruptcy Code or any other federal or state bankruptcy, insolvency, receivership or similar law in any jurisdiction relating to any other Loan Party, each Guarantor agrees that the Secured

8

Parties shall be entitled to receive irrevocable payment in full in cash of all Guaranteed Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Bankruptcy Code or any other federal or state bankruptcy, insolvency, receivership or similar law in any jurisdiction, whether or not constituting an allowed claim in such proceeding (“Post-Petition Interest”)) before such Guarantor receives payment of any Subordinated Obligations.

(iii) Turn-Over. After the occurrence and during the continuance of any Event of Default, each Guarantor shall, if the Administrative Agent so requests, collect, enforce and receive payments on account of the Subordinated Obligations as trustee for (or, in any jurisdiction whose law does not include the concept of trusts, for the account of) the Secured Parties and deliver such payments to the Administrative Agent on account of the Guaranteed Obligations (including all Post-Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Agreement.

(iv) Administrative Agent Authorization. After the occurrence and during the continuance of any Event of Default, the Administrative Agent is authorized and empowered (but without any obligation to so do), in its discretion, (i) in the name of each Guarantor, to collect and enforce, and to submit claims in respect of, the Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post-Petition Interest), and (ii) to require each Guarantor (A) to collect and enforce, and to submit claims in respect of, the Subordinated Obligations and (B) to pay any amounts received on such obligations to the Administrative Agent for application to the Guaranteed Obligations (including any and all Post-Petition Interest).

(b) Subject to the limitations set forth in Section 2.07, each Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower, any other Loan Party or any other insider guarantor that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under or in respect of the guarantee set forth in Article II or any other Loan Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Secured Party against the Borrower, any other Loan Party or any other insider guarantor or any Collateral, 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 Borrower, any other Loan Party or any other insider guarantor, 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, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under the guarantee set forth in Article II shall have been paid in full in cash, all Ancillary

9

Agreements secured hereunder shall have been terminated and the Commitments shall have expired or been terminated and each Guarantor agrees that it will not be entitled to bring any action, claim, suit or other proceeding in respect of any right it may have in respect of any payment on its guarantee until such time. If any amount shall be paid to any Guarantor in violation of the immediately preceding sentence at any time prior to the latest of (a) the payment in full in cash of the Guaranteed Obligations and all other amounts payable under the guarantee set forth in Article II and (b) the latest date of termination of all Ancillary Agreements secured hereunder, such amount shall be received and held in trust for the benefit of the Secured Parties, shall be segregated from other property and funds of such Guarantor and shall forthwith be paid or delivered to the Administrative Agent in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under the guarantee set forth in Article II, whether matured or unmatured, in accordance with the terms of the Loan Documents, or to be held as Collateral for any Guaranteed Obligations or other amounts payable under such guarantee thereafter arising. If (i) any Guarantor shall make payment to any Secured Party of all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other amounts payable under the guarantee set forth in Article II shall have been paid in full in cash, (iii) the Maturity Date shall have occurred, and (iv) all Ancillary Agreements secured hereunder shall have terminated or shall have been cash collateralized, the Administrative Agent will, at such Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment made by such Guarantor pursuant to such guarantee.

ARTICLE IV

Section 4.02. Limitation By Law. All rights, remedies and powers provided in this Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement are intended to be subject to all applicable mandatory provisions of law that may be controlling and to be limited to the extent necessary so that they shall not render this Agreement invalid or unenforceable, in whole or in part, under the provisions of any applicable law.

Section 4.03. Binding Effect; Several Agreement. This Agreement shall become effective as to any party to this Agreement when a counterpart hereof executed on behalf of such party shall have been delivered to the Administrative Agent and a

10

counterpart hereof shall have been executed on behalf of the Administrative Agent, and thereafter shall be binding upon such party and the Administrative Agent and their respective permitted successors and assigns, and shall inure to the benefit of such party, the Administrative Agent and the other Secured Parties and their respective permitted successors and assigns, except that no party shall have the right to assign or transfer its rights or obligations hereunder or any interest herein (and any such assignment or transfer shall be void) except as expressly contemplated by this Agreement or the Credit Agreement. This Agreement shall be construed as a separate agreement with respect to each party and may be amended, modified, supplemented, waived or released with respect to any party without the approval of any other party and without affecting the obligations of any other party hereunder.

Section 4.04. Successors and Assigns. Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the permitted successors and assigns of such party; and all covenants, promises and agreements by or on behalf of any Guarantor or the Administrative Agent that are contained in this Agreement shall bind and inure to the benefit of their respective permitted successors and assigns; provided that no Guarantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent.

Section 4.05. Administrative Agent’s Fees and Expenses; Indemnification. (a) The parties hereto agree that the Administrative Agent shall be entitled to reimbursement of its expenses incurred hereunder as provided in Section 9.05 of the Credit Agreement.

(b) Without limitation of its indemnification obligations under the other Loan Documents, each Guarantor jointly and severally agrees to indemnify the Administrative Agent and the other Indemnitees (as defined in Section 9.05 of the Credit Agreement) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including reasonable counsel fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of, (i) the execution, delivery or performance of this Agreement or any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto and thereto of their respective obligations thereunder or the consummation of the Transactions and other transactions contemplated hereby, (ii) the use of proceeds of the Loans or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, or to the Collateral, whether or not any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

(c) Subject to the terms of the Security Documents, any such amounts payable as provided hereunder shall be additional Guaranteed Obligations secured by the Collateral Agreement and the other Security Documents. The provisions of this Section 4.05

11

shall remain operative and in full force and effect regardless of the termination of this Agreement or any other Loan Document, the consummation of the transactions contemplated hereby, the repayment of any of the Guaranteed Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Administrative Agent or any other Secured Party. Subject to the limitations set forth in Section 2.07, all amounts due under this Section 4.05 shall be payable on written demand therefor, accompanied by reasonable documentation with respect to any reimbursement, indemnification or other amount requested.

Section 4.06. Waivers; Amendment. (a) No failure or delay by the Administrative Agent or any Secured Party in exercising any right, power or remedy hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy, or any abandonment or discontinuance of steps to enforce such a right, power or remedy, preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The rights, powers and remedies of the Administrative Agent and the Secured Parties hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights, powers or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 4.06, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default or Event of Default, regardless of whether the Administrative Agent or any Secured Party may have had notice or knowledge of such Default or Event of Default at the time. No notice or demand on any Loan Party in any case shall entitle any Loan Party to any other or further notice or demand in similar or other circumstances.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Loan Party or Loan Parties with respect to which such waiver, amendment or modification is to apply, subject to any consent required in accordance with Section 9.08 of the Credit Agreement.

Section 4.07. Severability. In the event any one or more of the provisions contained in this Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 4.08. Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile or other electronic transmission), each of which shall constitute an original but all of which when taken together shall constitute but

12

one contract, and shall become effective as provided in Section 4.03 hereof. Delivery of an executed counterpart to this Agreement by facsimile transmission or other electronic means shall be as effective as delivery of a manually signed original.

Section 4.09. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

(a) The terms of Sections 9.07, 9.11 and 9.15 of the Credit Agreement with respect to applicable law, consent to jurisdiction, venue, waiver of trial by jury and agent of process are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms (and, for the avoidance of doubt, as incorporated into this Agreement, Section 9.11 of the Credit Agreement shall apply to each party hereto).

(b) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 4.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Section 4.11. Termination or Release. (a) This Agreement and the guarantees made herein shall terminate on the Termination Date.

(b) A Guarantor shall automatically be released from its guarantee and its obligations hereunder (i) upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Guarantor ceases to be a Subsidiary of Intermediate Holdings or otherwise ceases to be a Guarantor, subject, if applicable, to consent required in accordance with Section 9.08 of the Credit Agreement and/or (ii) to the extent provided in Section 9.18 of the Credit Agreement.

(c) In connection with any termination or release pursuant to paragraph (a) or (b) of this Section 4.11, the Administrative Agent shall execute and deliver to any Guarantor, at such Guarantor’s expense, all documents that such Guarantor shall reasonably request to evidence such termination or release; provided that the Administrative Agent shall not be required to take any action under this Section 4.11(c) unless such Guarantor shall have delivered to the Administrative Agent together with such request, which may be incorporated into such request, a certificate of a Responsible Officer certifying that the transaction giving rise to such termination or release is permitted by the Credit Agreement and was consummated in compliance with the Loan Documents. Any execution and delivery of documents pursuant to this Section 4.11 shall be without recourse to or warranty by the Administrative Agent.

Section 4.12. Additional Guarantors. Upon execution and delivery by the Administrative Agent and any Subsidiary that is required to become a party hereto by Section 5.10 of the Credit Agreement of an instrument in the form of Exhibit I hereto

13

(with such additions to such form as the Administrative Agent and Intermediate Holdings may reasonably agree in the case of any such Subsidiary) (a “Supplement”), such entity shall become a Guarantor hereunder with the same force and effect as if originally named as a Guarantor herein. The execution and delivery of any such instrument shall not require the consent of any other party to this Agreement. The rights and obligations of each party to this Agreement shall remain in full force and effect notwithstanding the addition of any new party to this Agreement.

Section 4.12 of the Guarantee Agreement provides that additional Subsidiaries may become Guarantors under the Guarantee Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary (the “New Guarantor”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Guarantor under the Guarantee Agreement in order to induce the Lenders to make additional Loans and as consideration for Loans previously made.

Accordingly, the Administrative Agent and the New Guarantor agree as follows:

SECTION 1. In accordance with Section 4.12 of the Guarantee Agreement, the New Guarantor by its signature below becomes a Guarantor under the Guarantee Agreement with the same force and effect as if originally named therein as a Guarantor and the New Guarantor hereby agrees to all the terms and provisions of the Guarantee Agreement applicable to it as a Guarantor thereunder. In furtherance of the foregoing, the New Guarantor does hereby guarantee to the Administrative Agent the due and punctual payment of the Guaranteed Obligations as set forth in the Guarantee Agreement. Each reference to a “Guarantor” in the Guarantee Agreement and in this Supplement shall be deemed to include the New Guarantor. The Guarantee Agreement is hereby incorporated herein by reference.

SECTION 2. The New Guarantor represents and warrants to the Administrative Agent and the other Secured Parties that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, subject to (i) the effects of bankruptcy, insolvency, moratorium, reorganization, fraudulent conveyance or other similar laws affecting creditors’ rights generally, (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) implied covenants of good faith and fair dealing.

SECTION 3. The New Guarantor is a [company] duly [incorporated or organized] under the laws of [name of relevant jurisdiction].

SECTION 4. This Supplement may be executed in any number of counterparts, each of which shall constitute an original but all of which when taken together shall constitute but one contract.

In the event any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Guarantee Agreement shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8. All communications and notices hereunder shall (except as otherwise expressly permitted by the Guarantee Agreement) be in writing and given as provided in Section 9.01 of the Credit Agreement.
