All provisions of this Section 8 shall be subject to Section 9.9.

(b) until the prior indefeasible Discharge of First Lien Obligations has occurred, any payment or distribution from any source (whether or not from the Notes Issuer or any other Grantor) of any kind (whether in cash, Equity Interests or otherwise) to which the Second Lien Claimholders would be entitled but for the subordination provisions of this Agreement shall be made to the First Lien Collateral Agent for the benefit of the First Lien Claimholders, except that Second Lien Claimholders may receive Permitted Junior Securities; provided, that, if such payments are in a form other than cash or cash equivalents (the “Non-Cash Consideration”), the First Lien Collateral Agent, for the benefit of the First Lien Claimholders, shall be authorized to monetize such Non-Cash Consideration (other than Permitted Junior Securities) in its sole discretion and any cash proceeds shall be applied to the First Lien Obligations as provided herein. The application of such cash proceeds shall reduce the First Lien Obligations only to the extent of the actual cash payment indefeasibly received by the First Lien Claimholders, net of fees, costs and commissions; and

(c) if any payment or distribution from any source (whether or not from the Notes Issuer or any other Grantor) of any kind is made to the Second Lien Collateral Agent or any Second Lien Claimholders in respect of the Second Lien Obligations that, pursuant to this Agreement, should not have been made to them, such Second Lien Claimholders shall hold such payments or distributions in trust for the First Lien Claimholders and immediately pay and/or deliver such payments or distributions over to the First Lien Collateral Agent for the benefit of the First Lien Claimholders.

8.3. Default of First Lien Obligations.

(a) No payments of principal of, premium, if any, or interest (other than PIK Interest, which, for the avoidance of doubt, shall be permitted to be paid) on the Senior Secured Notes (nor any payments of any of the other Second Lien Obligations, including, without limitation, Second Lien Guarantees, fees, costs, expenses, indemnities and rescission or damage claims), nor shall any deposit be made pursuant to the Senior Secured Note Indenture, nor shall any of the Senior Secured Notes be purchased, redeemed or otherwise retired by the Notes Issuer or any other Grantor (collectively, “Notes Payments”) (except in the form of Permitted Junior Securities) if either of the following occurs (a “Payment Default”):

(i) any First Lien Obligation is not paid in full in cash when due (after giving effect to any applicable grace period); or

(ii) any other default under the First Lien Loan Documents occurs and the maturity of the First Lien Obligations is accelerated in accordance with the terms of the First Lien Loan Documents;

unless, in either case, the Payment Default has been cured or waived and any such acceleration has been rescinded or the Discharge of First Lien Obligations has occurred.

(b) During the continuance of any default described in Sections 7(b), 7(c), 7(d), 7(e), 7(f), 7(g), 7(h), 7(i), 7(j), or 7(k) of the First Lien Credit Agreement (as in effect on the First Amendment Effective Date) or comparable provisions of any agreement replacing or refinancing that agreement (a “Non-Payment Default”) under the First Lien Loan Documents pursuant to which the maturity of the First Lien Obligations may be accelerated without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, no Notes Payments shall be made (except in the form of PIK Interest, Permitted Junior Securities or a combination of PIK Interest and Permitted Junior Securities) for a period (a “Non-Payment Blockage Period”) commencing upon the receipt by the Second Lien Collateral Agent (with a copy to the Notes Issuer) of written notice (a “Blockage Notice”) of such Non-Payment Default from the First Lien Collateral Agent specifying an election to effect a Non-Payment Blockage Period and ending on the earliest of (i) 179 days after the receipt of the Blockage Notice, (ii) the date written notice to that effect is delivered to the Second Lien Collateral Agent and the Notes Issuer by the First Lien Collateral Agent; (iii) the date on which the default giving rise to such Blockage Notice is cured, waived or otherwise no longer continuing; and (iv) the date that the Discharge of First Lien Obligations has occurred.

(c) With respect to the occurrence of any Non-Payment Default only, unless the maturity of the First Lien Obligations shall have been accelerated, Notes Payments may be resumed after the end of the Non-Payment Blockage Period relating to such occurrence of such Non-Payment Default. The Second Lien Obligations shall not be subject to (i) more than two Non-Payment Blockage Periods in any consecutive 360-day period irrespective of the number of defaults with respect to the First Lien Obligations during such period or (ii) more than five Non-Payment Blockage Periods in the aggregate. There must be at least 181 days during any consecutive 360-day period during which no Non-Payment Blockage Period is in effect. Notwithstanding the foregoing, however, no default that existed or was continuing on the date of delivery of any Blockage Notice to the Second Lien Collateral Agent shall be, or be made, the basis for a subsequent Blockage Notice unless such default shall have been waived for a period of not less than 90 consecutive days (it being acknowledged that any subsequent action, or any breach of any financial covenants during the period after the date of delivery of a Blockage Notice, that, in either case, would give rise to a Non-Payment Default pursuant to any provisions under which a Non-Payment Default previously existed or was continuing shall constitute a new Non-Payment Default for this purpose).

(d) Upon the termination of any Non-Payment Blockage Period, the Notes Issuer shall forthwith pay to the Second Lien Collateral Agent for the account of the Second Lien Claimholders all amounts required to be paid to them under the Second Lien Loan Documents but were not paid because of the existence of this Agreement.

8.4. Acceleration of Payment of Second Lien Obligations. Subject in all respects to the terms and conditions of this Agreement, if payment of the Second Lien Obligations is accelerated because of a default under any of the Second Lien Loan Documents, the Second Lien Collateral Agent shall promptly notify the First Lien Collateral Agent of the acceleration; provided that any failure to give such notice shall have no effect whatsoever on the provisions of this Section 8.

8.5. Exercise of Remedies.

(a) Without limiting or modifying the provisions of Section 3 hereof (and in addition to the rights and obligations of the parties hereto set forth in Section 3 hereof) and to the extent not prohibited by the Trust Indenture Act of 1939, without the prior written consent of the First Lien Collateral Agent, the Second Lien Collateral Agent shall not, and no Second Lien Claimholder shall, exercise any of its rights and remedies with respect to the Second Lien Obligations until the earliest to occur of the following and in any event no earlier than 10 days after the First Lien Collateral Agent’s

receipt of written notice of the Second Lien Claimholder’s intention to exercise such rights and remedies after the occurrence of the earliest of any of the following:

(i) the Discharge of First Lien Obligations;

(ii) acceleration of the First Lien Obligations or the failure to pay the First Lien Obligations (or any part thereof) in full and in cash at maturity;

(iii) the occurrence of an Insolvency or Liquidation Proceeding;

(iv) the passage of 90 days from the later of (A) the date that the Second Lien Collateral Agent has declared an Event of Default under the Second Lien Loan Documents if any such Event of Default has not been cured or waived within such period and (B) the date on which the First Lien Collateral Agent received notice from the Second Lien Collateral Agent of such declaration of an Event of Default; and

(v) the exercise by the First Lien Collateral Agent or any First Lien Claimholder of any remedies under the First Lien Loan Documents.

(b) Notwithstanding anything contained herein to the contrary, if following the acceleration of the First Lien Obligations such acceleration is rescinded (whether or not any existing Event of Default under the First Lien Loan Documents has been cured or waived), then all actions taken by any Second Lien Claimholder in connection with the exercise of its rights and remedies will likewise be rescinded if such action is based solely on clauses (i), (ii) or (iv) of paragraph (a) of this Section 8.5.

8.6. Subordination May Not Be Impaired by Notes Issuer. No right of any First Lien Claimholder to enforce the subordination of the Second Lien Obligations shall be impaired by any act or failure to act by the Parent, the Company, the Notes Issuer or any Grantor or by their failure to comply with this Agreement.

8.7. Rights of Second Lien Collateral Agent and Paying Agent. Notwithstanding Section 8.3 hereof, the Second Lien Collateral Agent and any paying agent in respect of the Senior Secured Notes (the “Paying Agent”) may continue to make Notes Payments, and any Second Lien Claimholder may continue to accept Notes Payments, and shall not be charged with knowledge of the existence of facts that would prohibit the making or acceptance of any Notes Payments unless, not less than two Business Days prior to the date of such Notes Payment, the Second Lien Collateral Agent receives notice from the First Lien Collateral Agent that payments may not be made under this Section 8. Upon receipt of any such notice, the Second Lien Collateral Agent, any Paying Agent and any Second Lien Claimholder shall immediately turn over any such Notes Payment pursuant to the terms of this Agreement.

The Second Lien Collateral Agent in its individual or any other capacity shall be entitled to hold First Lien Obligations with the same rights it would have if it were not the Second Lien Collateral Agent. The registrar in respect of the Senior Secured Notes and the Paying Agent shall be entitled to do the same with like rights (provided that any such registrar or Paying Agent is not an Affiliate of the Parent, the Company, the Notes Issuer or any Grantor). The Second Lien Collateral Agent shall be entitled to all the rights set forth in this Agreement with respect to any First Lien Obligations which may at any time be held by it, to the same extent as any other First Lien Claimholder; and nothing in this Agreement shall deprive the Second Lien Collateral Agent of any of its rights as such First Lien Claimholder. Nothing in this Section 8 shall apply to claims of, or payments to, the Second Lien

Collateral Agent (solely in its capacity as an agent or trustee thereunder) under or pursuant to the Senior Secured Note Indenture.

8.8. Section 8 Not To Prevent Events of Default. The failure to make a Notes Payment by reason of any provision in this Section 8 shall not be construed as preventing the occurrence of an event of default under any of the Second Lien Loan Documents.

8.9. Trust Moneys Not Subordinated. Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations (as defined in the Senior Secured Note Indenture) held in trust by the Second Lien Collateral Agent or the Paying Agent for the payment of principal of and interest on the Senior Secured Notes pursuant to Article IV, Article XI or Article XIV of the Senior Secured Note Indenture shall not be subordinated to the prior payment of any First Lien Obligations or subject to the restrictions set forth in this Section 8, and none of the Second Lien Collateral Agent or the Second Lien Claimholders or the Paying Agent shall be obligated to pay over any such amount to the First Lien Collateral Agent or any First Lien Claimholder, provided that the subordination provisions of this Agreement were not violated at the time the applicable amounts were deposited in trust pursuant to Article IV, Article XI or Article XIV of the Senior Secured Note Indenture, as the case may be.

8.10. Trustee Entitled To Rely. Upon any payment or distribution pursuant to this Section 8, the Second Lien Collateral Agent and the Second Lien Claimholders shall be entitled to rely (a) upon any order or decree of a court of competent jurisdiction in which any Insolvency or Liquidation Proceedings are pending, (b) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Second Lien Collateral Agent or the Second Lien Claimholders or (c) upon the First Lien Collateral Agent for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the identity of the First Lien Claimholders, the amount of or payable in respect of the First Lien Obligations, the amount or amounts paid or distributed in respect of the First Lien Obligations and all other facts pertinent thereto or to this Agreement.

8.11. Trustee Not Fiduciary for First Lien Claimholders. The Trustee shall not be deemed to owe any fiduciary duty to the First Lien Claimholders by virtue of this Agreement or otherwise.

8.12. Reliance by First Lien Claimholders on Subordination Provisions. The Second Lien Collateral Agent, on behalf of the Second Lien Claimholders, acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each First Lien Claimholder to acquire and continue to hold, or to continue to hold, First Lien Obligations and each First Lien Claimholder shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, First Lien Obligations.

(i) Section 9.5 (Subrogation). Section 9.5 (formerly Section 8.5) is hereby amended by adding the following new sentence at the end thereof:

“Notwithstanding anything herein to the contrary, to the extent any indemnification obligation or contingent obligation becomes due and payable under the First Lien Loan Documents after the Discharge of the First Lien Obligations, the Second Lien Collateral Agent and Second Lien Claimholders shall promptly turn over any such amounts to the First Lien Collateral Agent for distribution to the First Lien Claimholders.”
