(a) Except as specifically set forth in Section 3.2, and subject to, and without limiting, the agreements and obligations of the Second Priority Secured Parties and the limitations of the rights of the Second Priority Secured Parties set forth in all of Section 5, the Second Priority Secured Parties may exercise rights and remedies, as holders of obligations that are not secured by any Lien, against the Borrower or any other Loan Party in accordance with the terms of the Second Priority Documents and applicable law. In the event that any Second Priority Secured Party becomes a judgment lien creditor in respect of Common Collateral as a result of its enforcement of its rights as a holder of obligations that are not secured by any Lien, such judgment lien shall be subject to the terms of this Agreement for all purposes (including in relation to the First Priority Liens and the First Priority Obligations) to the same extent as all other Liens securing the Second Priority Obligations are subject to the terms of this Agreement.

(b) Except as specifically set forth in Section 3.2, and subject to, and without limiting, the agreements and obligations of the Second Priority Secured Parties and the limitations of the rights of the Second Priority Secured Parties set forth in all of Section 5, nothing in this Agreement shall limit the rights of any Second Priority Secured Party to act in its capacity as holder of equity securities issued by Sirius XM Radio Inc.

3.4 Cooperation. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, agrees that each of them shall take such actions as the First Priority Representative shall request in connection with the exercise by the First Priority Secured Parties of their rights set forth herein.

3.5 No Additional Rights For the Loan Parties Hereunder. Except as provided in Section 3.6, if any First Priority Secured Party or Second Priority Secured Party shall enforce its rights or remedies in violation of the terms of this Agreement, no Loan Party shall be entitled to use such violation as a defense to any action by any First Priority Secured Party or Second Priority Secured Party, nor to assert such violation as a counterclaim or basis for set off or recoupment against any First Priority Secured Party or Second Priority Secured Party. Nothing in this Agreement is intended to or shall impair the obligations of the Borrower or any other Loan Party, which are absolute and unconditional, to pay the First Priority Obligations and the Second Priority Obligations as and when the same shall become due and payable in accordance with their terms.

3.6 Actions Upon Breach. (a) If any Second Priority Secured Party, contrary to this Agreement, commences or participates in any action or proceeding against any Loan Party or the Common Collateral, such Loan Party, with the prior written consent of the First Priority Secured Representative, may interpose as a defense or dilatory plea the making of this Agreement, and any First Priority Secured Party may intervene and interpose such defense or plea in its or their name or in the name of such Loan Party.

(b) Should any Second Priority Secured Party, contrary to this Agreement, in any way take, attempt to or threaten to take any action with respect to the Common Collateral (including, without limitation, any attempt to realize upon or enforce any remedy with respect to this Agreement), or fail to take any action required by this Agreement, any First Priority Secured Party (in its own name or in the name of the relevant Loan Party) or the relevant Loan Party may obtain relief against such Second Priority Secured Party by injunction, specific performance and/or other appropriate equitable relief, it being understood and agreed by the Second Priority Representative on behalf of each Second Priority Secured Party that (i) the First Priority Secured Parties’ damages from its actions may at that time be difficult to ascertain and may be irreparable, and (ii) each Second Priority Secured Party waives any defense that the Loan Parties and/or the First Priority Secured Parties cannot demonstrate damage and/or be made whole by the awarding of damages.

SECTION 4. Application Of Proceeds Of Common Collateral; Dispositions And Releases Of Common Collateral; Inspection and Insurance.

4.1 Application of Proceeds; Turnover Provisions. All proceeds of Common Collateral (including without limitation any interest earned thereon) resulting from the sale, collection or other disposition of Common Collateral, whether or not pursuant to an Insolvency Proceeding, shall be distributed as follows: first to the First Priority Representative for application to the First Priority Obligations in accordance with the terms of the First Priority Documents, until the First Priority Obligations Payment Date has occurred and thereafter, to the Second Priority Representative for application in accordance with the Second Priority Documents. Until the occurrence of the First Priority Obligations Payment Date, any Common Collateral, including without limitation any such Common Collateral constituting proceeds, that may be received by any Second Priority Secured Party in violation of this Agreement shall be segregated and held in trust and promptly paid over to the First Priority Representative, for the benefit of the First Priority Secured Parties, in the same form as received, with any necessary endorsements, and each Second Priority Secured Party hereby authorizes the First Priority Representative to make any such endorsements as agent for the Second Priority Representative (which authorization, being coupled with an interest, is irrevocable).

4.2 Releases of Second Priority Lien. (a) Until the First Priority Obligations Payment Date has occurred, upon any release, sale or disposition of Common Collateral permitted pursuant to the terms of the First Priority Documents that results in the release of the First Priority Lien on any Common Collateral (including without limitation any sale or other disposition pursuant to any Enforcement Action), the Second Priority Lien on such Common Collateral (excluding any portion of the proceeds of such Common Collateral remaining after the First Priority Obligations Payment Date occurs) shall be automatically and unconditionally released with no further consent or action of any Person.

(b) The Second Priority Representative shall promptly execute and deliver such release documents and instruments and shall take such further actions as the First Priority Representative shall request to evidence any release of the Second Priority Lien described in paragraph (a). The Second Priority Representative hereby appoints the First Priority Representative and any officer or duly authorized person of the First Priority Representative, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power of attorney in the place and stead of the Second Priority Representative and in the name of the Second Priority Representative or in the First Priority Representative’s own name, from time to time, in the First Priority Representative’s sole discretion, for the purposes of carrying out the terms of this Section 4.2, to take any and all appropriate action and to execute and deliver any and all documents and instruments as may be necessary or desirable to accomplish the purposes of this Section 4.2, including, without limitation, any financing statements, endorsements, assignments, releases or other documents or instruments of transfer (which appointment, being coupled with an interest, is irrevocable).

4.3 Inspection Rights and Insurance. (a) Any First Priority Secured Party and its representatives and invitees may at any time inspect, repossess, remove and otherwise deal with the Common Collateral, and the First Priority Representative may advertise and conduct public auctions or private sales of the Common Collateral, in each case without notice to, the involvement of or interference by any Second Priority Secured Party or liability to any Second Priority Secured Party.

(b) Until the First Priority Obligations Payment Date has occurred, the First Priority Representative will have the sole and exclusive right (i) to be named as additional insured and loss payee under any insurance policies maintained from time to time by any Loan Party (except that the Second Priority Representative shall have the right to be named as additional insured and loss payee so long as its second lien status is identified in a manner reasonably satisfactory to the First Priority Representative); (ii) to adjust or settle any insurance policy or claim covering the Common Collateral in the event of any loss thereunder and (iii) to approve any award granted in any condemnation or similar proceeding affecting the Common Collateral.

4.4 Purchase Right. Without prejudice to the enforcement of the rights and remedies of the First Priority Representative or the First Priority Secured Parties with respect to the Common Collateral, within five Business Days after (a) the acceleration of all of the Credit Agreement Obligations in accordance with the Credit Agreement or (b) the commencement of an Insolvency Proceeding with respect to any Loan Party, the Credit Agreement Representative, on behalf of the Credit Agreement Lenders, shall offer to the Second Priority Creditors in writing the option to purchase from the Credit Agreement Lenders without recourse, representation or warranty (except for representations and warranties required to be made by assigning lenders pursuant to the Assignment and Assumption in the form attached to the Credit Agreement as of the date hereof) all, but not less than all, of the Credit Agreement Obligations outstanding at the time of such purchase (including any unfunded commitments under the Credit Agreement and all obligations in respect of letters of credit) and all other rights, obligations and claims of the Credit Agreement Lenders (each of the Credit Agreement Lenders so agreeing by its acceptance of the benefits of the Credit Agreement), and, upon any such purchase, such Second Priority Creditors shall assume and the Credit Agreement Lenders shall be relieved of their commitments and other obligations under the Credit Agreement (including, without limitation, any obligation to make loans and any obligation to participate in letters of credit), at par plus accrued and unpaid interest, fees, expenses, penalties, premiums including the Repayment Premium (as defined in the Credit Agreement), breakage costs, the net amount owing to First Priority Qualified Counterparties in respect of Hedging Obligations, the amount owing to First Priority Qualified Counterparties in respect of Cash Management Obligations, and any other amounts constituting First Priority Obligations (including any unpaid amounts payable to the Credit Agreement Representative or any other agent acting under the Credit Agreement and associated documents, which amounts shall be paid directly to such parties). If one or more of the Second Priority Creditors choose to exercise such right, they must irrevocably notify the Credit Agreement Representative thereof within 10 days after the receipt of the offer notice delivered by the Credit Agreement Representative, and the parties shall endeavor to close promptly thereafter, and in any event within 10 Business Days following notice of the exercise of the Second Priority Creditors’ purchase right. If any of the Second Priority Creditors chooses to exercise such right, then contemporaneously with such purchase pursuant thereto, any of the providers of DIP Financing that are also Credit Agreement Lenders (the “DIP Credit Agreement Lenders”) may in each of their sole discretion require such Second Priority Creditor to purchase, without recourse, representation or warranty all, but not less than all, of its DIP Financing Obligations outstanding at the time of such purchase (including any unfunded commitments under the DIP Financing and all obligations in respect of letters of credit) and all of its other rights, obligations and claims in respect of the DIP Financing and, upon any such purchase,

such Second Priority Creditors shall assume and the applicable DIP Credit Agreement Lenders shall be relieved of their commitments and other obligations under the DIP Financing (including, without limitation, any obligation to make loans and any obligation to participate in letters of credit), at par plus accrued and unpaid interest, fees, expenses, penalties, premiums, breakage costs, the net amount owing pursuant to secured hedging obligations, the amount owing pursuant to secured cash management, depositary, treasury management and similar obligations, and any other amounts constituting DIP Financing Obligations. No DIP Credit Agreement Lender shall have any obligation to sell its DIP Financing Obligations.

5.1 Filing of Motions. Subject only to the Second Priority Creditors’ rights under Section 3.1(a) through (d) and Section 5.2, until the First Priority Obligations Payment Date has occurred, the Second Priority Representative agrees on behalf of itself and the other Second Priority Secured Parties that no Second Priority Secured Party shall, in or in connection with any Insolvency Proceeding, file any pleadings or motions, take any position at any hearing or proceeding of any nature, or otherwise take any action whatsoever, in each case in respect of any of the Common Collateral, including, without limitation, with respect to the determination of any Liens or claims held by the First Priority Representative (including the validity and enforceability thereof) or any other First Priority Secured Party or the value of any claims of such parties under Section 506(a) of the Bankruptcy Code or otherwise.

5.2 Financing Matters. If any Loan Party becomes subject to any Insolvency Proceeding, and if the First Priority Representative or the other First Priority Secured Parties desire to consent (or not object) to the use of cash collateral under the Bankruptcy Code or to provide financing to any Loan Party under the Bankruptcy Code or to consent (or not object) to the provision of such financing to any Loan Party by any third party (any such financing, including any such financing (x) which represents an advance by some or all of the First Priority Secured Parties following repayment of amounts of First Priority Obligations with cash collateral or (y) the proceeds of which are used, in whole or in part, to repay First Priority Obligations owned to some or all of the First Priority Creditors, the “DIP Financing”), then the Second Priority Representative agrees, on behalf of itself and the other Second Priority Secured Parties, that each Second Priority Secured Party (a) will be deemed to have consented to, will raise no objection to, nor support any other Person objecting to, the use of such cash collateral or to such DIP Financing, (b) will not request or accept adequate protection or any other relief in connection with the use of such cash collateral or such DIP Financing except as set forth in paragraph 5.4 below and (c) to the extent the Liens securing the First Priority Obligations are subordinated to or pari passu with such DIP Financing, the

Second Priority Representative will subordinate its Liens in the Collateral to (i) the Liens securing such DIP Financing (and all obligations relating thereto), (ii) to any adequate protection provided to the First Priority Secured Parties and (iii) to any “carve-out” agreed to by the First Priority Representative or the other First Priority Secured Parties, and (d) agrees that notice received two calendar days prior to the entry of an order approving such usage of cash collateral or approving such financing shall be adequate notice; provided that (i) after taking into account the principal amount of the DIP Financing on any date, the sum of the outstanding principal amount of any First Priority Obligations and any DIP Financing shall not exceed the First Priority Cap and (ii) the foregoing shall not prevent the Second Priority Secured Parties from proposing any other DIP Financing to any Loan Party or the bankruptcy court or making or supporting any motion in respect thereof or defending or otherwise responding to any motion in opposition thereto, in each case so long as such action by any Second Priority Secured Party does not contravene any of the agreements, obligations and limitations on the rights of the Second Priority Secured Parties set forth in this Agreement (and the Second Priority Secured Parties acknowledge that such agreements, obligations and limitations are not in any way affected by the right set forth in this clause (ii)), and so long as such action does not in any way lessen or modify the rights of the First Priority Secured Parties set forth in this Agreement or otherwise available pursuant to applicable law (including the right to object to any proposed DIP Financing). No Second Priority Secured Party shall propose, support or enter into any DIP Financing if the effect of such DIP Financing would be that the Second Priority Obligations would no longer be subordinated to the First Priority Obligations in the manner set forth in this Agreement, or the Second Priority Secured Parties would recover any payments they are not otherwise entitled to under this Agreement, including by way of adequate protection.

5.3 Relief From the Automatic Stay. The Second Priority Representative agrees, on behalf of itself and the other Second Priority Secured Parties, that none of them will seek relief from the automatic stay or from any other stay in any Insolvency Proceeding or take any action in derogation thereof, in each case in respect of any Common Collateral, without the prior written consent of the First Priority Representative.

5.4 Adequate Protection. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, agrees that none of them shall object, contest, or support any other Person objecting to or contesting, (a) any request by the First Priority Representative or the other First Priority Secured Parties for adequate protection or any adequate protection provided to the First Priority Representative or the other First Priority Secured Parties or (b) any objection by the First Priority Representative or any other First Priority Secured Parties to any motion, relief, action or proceeding based on a claim of a lack of adequate protection or (c) the payment of interest, fees, expenses or other amounts to the First Priority Representative or any other First Priority Secured Party under Section 506(b) or 506(c) of the Bankruptcy Code or otherwise. Notwithstanding anything contained in this

Section and in Section 5.2(b) (but subject to all other provisions of this Agreement, including, without limitation, Sections 5.2(a) and 5.3), in any Insolvency Proceeding, (i) if the First Priority Secured Parties (or any subset thereof) are granted adequate protection consisting of additional collateral (with replacement liens on such additional collateral) and superpriority claims in connection with any DIP Financing or use of cash collateral, and the First Priority Secured Parties do not object to the adequate protection being provided to the First Priority Secured Parties, then in connection with any such DIP Financing or use of cash collateral the Second Priority Representative, on behalf of itself and any of the Second Priority Secured Parties, may seek or accept adequate protection consisting solely of (x) a replacement Lien on the same additional collateral, subordinated to the Liens securing the First Priority Obligations and such DIP Financing on the same basis as the other Liens securing the Second Priority Obligations are so subordinated to the First Priority Obligations under this Agreement and/or (y) superpriority claims junior in all respects to the superpriority claims granted to the First Priority Secured Parties, provided, however, that the Second Priority Representative shall have irrevocably agreed, pursuant to Section 1129(a)(9) of the Bankruptcy Code, on behalf of itself and the Second Priority Secured Parties, in any stipulation and/or order granting such adequate protection, that such junior superpriority claims may be paid under any plan of reorganization in any combination of cash, debt, equity or other property having a value on the effective date of such plan equal to the allowed amount of such claims and (ii) in the event the Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, seeks or accepts adequate protection in accordance with clause (i) above and such adequate protection is granted in the form of additional collateral, then the Second Priority Representative, on behalf of itself or any of the Second Priority Secured Parties, agrees that the Second Priority Secured Parties will not object to the First Priority Representative being granted (and the intent is for the First Priority Representative to be granted) a senior Lien on such additional collateral as security for the First Priority Obligations and any such DIP Financing and that any Lien on such additional collateral securing the Second Priority Obligations shall be subordinated to the Liens on such collateral securing the First Priority Obligations and any such DIP Financing (and all obligations relating thereto) and any other Liens granted to the First Priority Secured Parties as adequate protection, with such subordination to be on the same terms that the other Liens securing the Second Priority Obligations are subordinated to such First Priority Obligations under this Agreement. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, agrees that except as expressly set forth in this Section none of them shall seek or accept adequate protection without the prior written consent of the First Priority Representative.

5.5 Avoidance Issues. If any First Priority Secured Party is required in any Insolvency Proceeding or otherwise to disgorge, turn over or otherwise pay to the estate of any Loan Party, because such amount was avoided or ordered to be paid or disgorged for any reason, including without limitation because it was found to be a fraudulent or preferential

transfer, any amount (a “Recovery”), whether received as proceeds of security, enforcement of any right of set-off or otherwise, then the First Priority Obligations shall be reinstated to the extent of such Recovery and deemed to be outstanding as if such payment had not occurred and the First Priority Obligations Payment Date shall be deemed not to have occurred. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto. The Second Priority Secured Parties agree that none of them shall be entitled to benefit from any avoidance action affecting or otherwise relating to any distribution or allocation made in accordance with this Agreement, whether by preference or otherwise, it being understood and agreed that the benefit of such avoidance action otherwise allocable to them shall instead be allocated and turned over for application in accordance with the priorities set forth in this Agreement.

5.6 Asset Dispositions in an Insolvency Proceeding. Neither the Second Priority Representative nor any other Second Priority Secured Party shall, in an Insolvency Proceeding or otherwise, oppose any sale or disposition of any assets of any Loan Party that is supported by the First Priority Secured Parties, and the Second Priority Representative and each other Second Priority Secured Party will be deemed to have consented under Section 363 of the Bankruptcy Code (and otherwise) to any sale supported by the First Priority Secured Parties and to have released their Liens on such assets.

5.7 Separate Grants of Security and Separate Classification. Each Second Priority Secured Party acknowledges and agrees that (a) the grants of Liens pursuant to the First Priority Security Documents and the Second Priority Security Documents constitute two separate and distinct grants of Liens and (b) because of, among other things, their differing rights in the Common Collateral, the Second Priority Obligations are fundamentally different from the First Priority Obligations and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency Proceeding. To further effectuate the intent of the parties as provided in the immediately preceding sentence, if it is held that the claims of the First Priority Secured Parties and Second Priority Secured Parties in respect of the Common Collateral constitute only one secured claim (rather than separate classes of senior and junior secured claims), then the parties hereto hereby acknowledge and agree that all distributions shall be made as if there were separate classes of senior and junior secured claims against the Loan Parties in respect of the Common Collateral (with the effect being that, to the extent that the aggregate value of the Common Collateral is sufficient (for this purpose ignoring all claims held by the Second Priority Secured Parties), the First Priority Secured Parties shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of Post-Petition Interest before any distribution of Common Collateral or proceeds of Common Collateral is made in respect of the claims held by the Second Secured Priority Secured

Parties, with the Second Priority Secured Parties hereby acknowledging and agreeing to turn over to the First Priority Secured Parties Common Collateral or proceeds of Common Collateral otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Second Priority Secured Parties.

5.8 No Waivers of Rights of First Priority Secured Parties. Nothing contained herein shall prohibit or in any way limit the First Priority Representative or any other First Priority Secured Party from objecting in any Insolvency Proceeding or otherwise to any action taken by any Second Priority Secured Party, including the seeking by any Second Priority Secured Party of adequate protection (except as provided in Section 5.4) or the asserting by any Second Priority Secured Party of any of its rights and remedies under the Second Priority Documents or otherwise.

5.9 Plans of Reorganization. No Second Priority Secured Party shall, with respect to the Second Priority Obligations, support or vote in favor of any plan of reorganization (and each shall be deemed to have voted to reject any plan of reorganization) unless such plan (a) pays off, in cash in full, all First Priority Obligations on the effective date of such plan or (b) is accepted by the class of holders of First Priority Obligations voting thereon and is supported by the First Priority Representative.

5.10 Other Matters. To the extent that the Second Priority Representative or any Second Priority Secured Party has or acquires rights under Section 363 or Section 364 of the Bankruptcy Code with respect to any of the Common Collateral, the Second Priority Representative agrees, on behalf of itself and the other Second Priority Secured Parties not to assert any of such rights without the prior written consent of the First Priority Representative; provided that if requested by the First Priority Representative, the Second Priority Representative shall timely exercise such rights in the manner requested by the First Priority Representative, including any rights to payments in respect of such rights. Notwithstanding the foregoing, the Second Priority Secured Parties may exercise any rights they may have to credit bid under Section 363(k) of the Bankruptcy Code if the First Priority Obligations Payment Date will occur as a result of the consummation of the transaction contemplated by such credit bid.

5.11 Effectiveness in Insolvency Proceedings. This Agreement, which the parties hereto expressly acknowledge is a “subordination agreement” under Section 510(a) of the Bankruptcy Code, shall be effective before, during and after the commencement of an Insolvency Proceeding.

(a) Each Loan Party and the Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, agrees that it shall not at any time (i) execute or deliver any amendment or other modification to any of the Second Priority Documents inconsistent with or in violation of this Agreement or (ii) execute or deliver any amendment or other modification to any of the Second Priority Documents without the written consent of the First Priority Representative if such amendment would:

(A) increase the aggregate principal amount of loans, letters of credit, bankers acceptances or other similar extension of credit under the Second Priority Documents or commitments therefor so that the aggregate principal amount of such loans, letters of credit, bankers acceptances, similar extensions of credit and commitments is in excess of $150,000,000 less (a) the amount of all repayments and prepayments of principal applied to any term loans constituting Second Priority Obligations and (b) the amount of all repayments and prepayments of any revolving loans or reimbursement of drawings under letters of credit constituting Second Priority Obligations, to the extent accompanied by a permanent reduction of commitments under the applicable revolving credit facility or letter of credit commitment amount (excluding reductions in sub-facility commitments not accompanied by a corresponding permanent reduction in the revolving facility or letter of credit commitment amount);

(B) modify the method of computing interest or increase the interest rate (including by any increase in the “applicable margin” or similar component of the interest rate) or yield provisions applicable to the Second Priority Obligations or any letter of credit fee, commitment fee, facility fee, utilization fee, or similar fee (excluding increases resulting from (I) increases in the underlying reference rate not caused by any amendment, supplement, or modification of the Second Priority Documents, (II) accrual of interest at the default rate as set forth in the Second Priority Documents on the date hereof or (III) the operation of Section 6(b)(i)(x) hereof);

(C) change any covenants, defaults or events of default (including the addition of defaults or events of default not contained in the Second Priority Documents as of the date hereof) in any manner that makes them more restrictive, in any material respect, as to any Loan Party except to make conforming changes to match changes made to the First Priority Documents so as to preserve, in connection with any amendments to the First Priority Documents, on substantially similar economic terms, the differential (if any) that exists on the date hereof between such covenants, defaults or events of default in the First Priority Documents and such covenants, defaults or events of default Second Priority Documents;

(D) change to earlier dates any dates upon which payment of principal or interest are due thereon or otherwise alter any provisions that decrease the weighted average life to maturity;

(E) change the prepayment, redemption or defeasance provisions thereof if the effect of such change is to require any new payment or accelerate the payment date of any existing payment obligation;

(F) would permit the assignment of, or sale of any participations in, any Second Priority Obligations to any Loan Party or any Affiliate or Subsidiary of any Loan Party (other than any Liberty Party (as defined under the Existing Second Priority Agreement); or

(G) change or amend any other term of the Second Priority Documents if such change or amendment would result in a default under the First Priority Documents, increase the obligations of any Loan Party or be adverse to the First Priority Secured Parties.

It will also be deemed a violation of this Section 6(a) if any Second Priority Secured Party, Loan Party, or Affiliate of any Loan Party takes an action that would be prohibited under the Second Lien Documents without execution of one or more of the foregoing restricted amendments.

(b) Each Loan Party and the Credit Agreement Representative, on behalf of itself and the Credit Agreement Lenders, agrees that it shall not at any time prior to the existence of an Insolvency Proceeding (i) execute or deliver any amendment or other modification to any of the First Priority Documents inconsistent with or in violation of this Agreement or (ii) execute or deliver any amendment or other modification to any of the First Priority Documents which would increase (x) the rate of interest (excluding increases resulting from the accrual of interest at the default rate) by more than three percent (3%) per annum (provided that if any amendment to the Credit Agreement increasing the rate of interest by three percent (3%) per annum or less is effected, then the rate of interest in the Existing Second Priority Agreement shall automatically be increased by an equal amount) or (y) the aggregate principal amount of loans, letters of credit, bankers acceptances or similar extensions of credit under the First Priority Documents or commitments therefor so that the aggregate principal amount of such loans, letters of credit, bankers acceptances, similar extensions of credit and commitments is in excess of the First Priority Cap without the written consent of the Second Priority Representative.

(c) In the event the First Priority Representative enters into any amendment, waiver or consent in respect of any of the First Priority Security Documents for the purpose of adding to, or deleting from, or waiving or consenting to any departures from any provisions of, any First Priority Security Document or changing in any manner the rights of

any parties thereunder, then such amendment, waiver or consent shall apply automatically to any comparable provision of the Comparable Second Priority Security Document without the consent of or action by any Second Priority Secured Party (with all such amendments, waivers and modifications subject to the terms hereof); provided that, (i) no such amendment, waiver or consent shall have the effect of (A) removing assets subject to the Lien of any Second Priority Security Document, except to the extent that a release of such Lien is permitted by Section 4.2 and provided that there is a corresponding release of the Liens securing the First Priority Obligations, (B) permitting other Liens on the Collateral not permitted under the terms of the Second Priority Documents or Section 5 or (C) imposing any duties on the Second Priority Representative without its consent, (ii) any such amendment, waiver or consent that materially and adversely affects the rights of the Second Priority Secured Parties and does not affect the First Priority Secured Parties in a like or similar manner shall not apply to the Second Priority Security Documents without the consent of the Second Priority Representative and (iii) notice of such amendment, waiver or consent shall be given to the Second Priority Representative no later than 10 Business Days after its effectiveness, provided that the failure to give such notice shall not affect the effectiveness and validity thereof.

7.1 Reliance. The First Priority Documents are deemed to have been executed and delivered, and all extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement. The Second Priority Representative, on behalf of it itself and the Second Priority Secured Parties, expressly waives all notice of the acceptance of and reliance on this Agreement by the First Priority Secured Parties. The Second Priority Documents are deemed to have been executed and delivered and all extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement.

7.3 No Waivers. No right or benefit of any party hereunder shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of such party or any other party hereto or by any noncompliance by any Loan Party with the terms and conditions of any of the First Priority Documents or the Second Priority Documents.

8.1 First Priority Obligations Unconditional. All rights and interests of the First Priority Secured Parties hereunder, and all agreements and obligations of the Second Priority Secured Parties (and, to the extent applicable, the Loan Parties) hereunder, shall remain in full force and effect irrespective of:

(b) any change in the time, place or manner of payment of, or in any other term of, all or any portion of the First Priority Obligations, or any amendment, waiver or other modification, whether by course of conduct or otherwise, or any refinancing, replacement, refunding or restatement of any First Priority Document;

(c) prior to the First Priority Obligations Payment Date, any exchange, release, voiding, avoidance or non-perfection of any security interest in any Common Collateral or any other collateral, or any release, amendment, waiver or other modification, whether by course of conduct or otherwise, or any refinancing, replacement, refunding or restatement of all or any portion of the First Priority Obligations or any guarantee or guaranty thereof; or

9.2 Continuing Nature of Provisions. This Agreement shall continue to be effective, and shall not be revocable by any party hereto, until the First Priority Obligations Payment Date shall have occurred. This is a continuing agreement and the First Priority Secured Parties and the Second Priority Secured Parties may continue, at any time and without notice to the other parties hereto, to extend credit and other financial accommodations, lend monies and provide indebtedness to, or for the benefit of, Borrower or any other Loan Party on the faith hereof.

The Second Priority Representative and the First Priority Representative hereby agree that no party shall have any duty to advise any other party of information known to it regarding such condition or any such circumstances. In the event the Second Priority Representative or the First Priority Representative, in its sole discretion, undertakes at any time or from time to time to provide any information to any other party to this Agreement, it shall be under no obligation (a) to provide any such information to such other party or any other party on any subsequent occasion, (b) to undertake any investigation not a part of its regular business routine, or (c) to disclose any other information.

9.5 Governing Law. This Agreement shall be construed in accordance with and governed by the law of the State of New York, except as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than the State of New York are governed by the laws of such jurisdiction.

9.6 Submission to Jurisdiction. (a) Each Credit Agreement Lender, each Second Priority Secured Party and each Loan Party hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each such party hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each such party agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the any First Priority Secured Party or Second Priority Secured Party may otherwise have to bring any action or proceeding against any Loan Party or its properties in the courts of any jurisdiction.

(b) Each Credit Agreement Lender, each Second Priority Secured Party and each Loan Party hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so (i) any objection it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (a) of this Section and (ii) the defense of an inconvenient forum to the maintenance of such action or proceeding.

(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.7. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Unless otherwise specifically provided herein, any notice or other communication herein required or permitted to be given shall be in writing and may be personally served, telecopied, or sent by overnight express courier service or United States mail and shall be deemed to have been given when delivered in person or by courier service, upon receipt of a telecopy or five days after deposit in the United States mail (certified, with postage prepaid and properly addressed).

This Agreement shall be binding upon and inure to the benefit of each of the parties hereto and each of the First Priority Secured Parties and Second Priority Secured Parties and their respective successors and assigns, and nothing herein is intended, or shall be construed to give, any other Person any right, remedy or claim under, to or in respect of this Agreement or any Common Collateral.

9.10 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

9.11 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.
