Section 2.4 Secured Parties Not Liable. Notwithstanding any other provision contained in this Agreement, the Pledgor shall remain liable under the Operating Agreement to observe and perform all of the conditions and obligations to be observed and performed by the Pledgor thereunder. None of the Collateral Agent, any other Secured Party or any of their respective directors, officers, employees, affiliates or agents shall have any obligations or liability under or with respect to any Pledged Collateral by reason of or arising out of this Agreement, except as set forth in Section 9-207 of the UCC as in effect from time to time in the State of New York, or the receipt by the Collateral Agent of any payment relating to any Pledged Collateral, nor shall any of the Collateral Agent, any other Secured Party or any of their respective directors, officers, employees, affiliates or agents be obligated in any manner to (a) perform any of the obligations of the Pledgor under or pursuant to the Operating Agreement or any other agreement to which the Pledgor is a party, (b) make any payment or inquire as to the nature or sufficiency of any payment or performance with respect to any Pledged Collateral, (c) present or file any claim or collect the payment of any amounts or take any action to enforce any performance with respect to the Pledged Collateral or (d) take any other action whatsoever with 6 11 respect to the Pledged Collateral, in each case, other than as required under this Agreement and the other Security Documents.

ARTICLE 5 EXERCISE OF REMEDIES UPON AN EVENT OF DEFAULT _______The provisions of this Article 5 shall apply only upon the occurrence and during the continuance of an Event of Default. Section 5.1 Remedies Generally. If an Event of Default shall have occurred and be continuing, the Collateral Agent, upon directions from the Secured Parties pursuant the Intercreditor Agreement, or as otherwise expressly provided herein, may exercise, in addition to all other rights and remedies granted in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the UCC in effect from time to time in any relevant jurisdiction and all other rights and remedies available at law or in equity. Section 5.2 Sale of Pledged Collateral. (a) Without limiting the generality of Section 5.1, the Collateral Agent, upon directions from the Secured Parties pursuant to the Intercreditor Agreement, or as otherwise expressly provided herein, 12 17 may, with notice as required by applicable law, sell the Pledged Collateral or any part thereof in one or more parcels at public or private sale or at any of the Collateral Agent's corporate trust office or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Collateral Agent may reasonably deem commercially reasonable, irrespective of the impact of any such sales on the market price of the Pledged Collateral at any such sale. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days' notice to the Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Pledged Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Assuming that such sales are made in compliance with federal and state securities laws and the UCC, the Collateral Agent shall incur no liability as a result of the sale of the Pledged Collateral, or any part thereof, at any public or private sale. The Pledgor hereby waives any claims against the Collateral Agent arising by reason of the fact that the price at which any Pledged Collateral may have been sold at such a private sale, if commercially reasonable, was less than the price which might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer the Pledged Collateral to more than one offeree. (b) The Pledgor recognizes that the Collateral Agent, upon directions from the Secured Parties pursuant to the Intercreditor Agreement, or as otherwise expressly provided herein, may elect to sell all or any part of the Pledged Collateral to one or more purchasers in privately negotiated transactions in which the purchasers will be obligated to agree, among other things, to acquire the Pledged Collateral for their own account, for investment and not with a view to the distribution or resale thereof. The Pledgor acknowledges that any such private sales may be at prices and on terms less favorable than those obtainable through a public sale (including, without limitation, a public offering made pursuant to a registration statement under the Securities Act of 1933, as amended (the "Securities Act")), and the Pledgor and the Collateral Agent agree that such private sales shall be made in a commercially reasonable manner and that the Collateral Agent has no obligation to engage in 13 18 public sales and no obligation to delay sale of any Pledged Collateral to permit the issuer thereof to register the Pledged Collateral for a form of public sale requiring registration under the Securities Act. If the Collateral Agent, upon directions from the Secured Parties pursuant to the Intercreditor Agreement, or as otherwise expressly provided herein, determines to exercise its right to sell any or all of the Pledged Collateral, upon written request, the Pledgor shall, from time to time, furnish to the Collateral Agent all such information as the Collateral Agent may request in order to determine the number of shares and other instruments included in the Pledged Collateral which may be sold by the Collateral Agent as exempt transactions under the Securities Act and rules of the Securities and Exchange Commission thereunder, as the same are from time to time in effect. Section 5.3 Purchase of Pledged Collateral. The Collateral Agent may be a purchaser of the Pledged Collateral or any part thereof or any right or interest therein at any sale thereof, whether pursuant to foreclosure, power of sale or otherwise hereunder and the Collateral Agent may apply the purchase price to the payment of the Secured Obligations. Any purchaser of all or any part of the Pledged Collateral shall, upon any such purchase, acquire good title to the Pledged Collateral so purchased, free of the security interests created by this Agreement. Section 5.4 Application of Proceeds. The Collateral Agent shall apply any proceeds from time to time held by it and the net proceeds of any collection, recovery, receipt, appropriation, realization or sale with respect to the Pledged Collateral in accordance with Section 5.3 of the Intercreditor Agreement. For avoidance of doubt, it is understood that the Subsidiary Guarantor shall remain liable to the extent of any deficiency between the amount of proceeds of the Pledged Collateral and the aggregated amount of the Secured Obligations in accordance with the Finance Documents. ARTICLE 6 MISCELLANEOUS PROVISIONS Section 6.1 Notices. Unless otherwise specifically herein provided, all notices required or permitted under the terms and provisions hereof shall be in writing and any such notice shall become effective if given in accordance with the provisions of Section 12.5 of the Indenture 14 19 Section 6.2 Continuing Security Interest. This Agreement shall create a continuing security interest in the Pledged Collateral until the release thereof pursuant to Section 6.3. Section 6.3 Release. (a) Upon the indefeasible payment in full of the Secured Obligations in cash or cash equivalents and the termination of all commitments of the Secured Parties under the Finance Documents, the Collateral Agent, upon the written request, and at the expense, of the Pledgor, shall execute and deliver all such documentation necessary to release the security interest created pursuant to this Agreement. (b) Upon the sale or disposition of any portion of the Pledged Collateral permitted pursuant to the terms of the Finance Documents, including, but not limited to, any Permitted Asset Sale, the purchaser of such portion of the Pledged Collateral shall, upon such purchase, acquire good title to the Pledged Collateral so purchased, free of the security interests created by this Agreement. The Collateral Agent, upon the written request, and at the expense, of the Pledgor, shall execute and deliver all such documentation necessary to evidence such release of the security interest created in such Pledged Collateral pursuant to this Agreement. Section 6.4 Reinstatement. This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any amount received by the Collateral Agent or any other Secured Party hereunder or pursuant hereto is rescinded or must otherwise be restored or returned by the Collateral Agent or such Secured Party upon a Bankruptcy Event of the Pledgor or the Subsidiary Guarantor or upon the appointment of any intervenor or conservator of, or trustee or similar official for, the Pledgor or the Subsidiary Guarantor or any substantial part of the Pledgor's or the Subsidiary Guarantor's assets, or upon the entry of an order by any court avoiding the payment of such amount, or otherwise, all as though such payments had not been made. Section 6.5 Independent Security. The security provided for in this Agreement shall be in addition to and shall be independent of every other security which the Secured Parties may at any time hold for any of the Secured Obligations hereby secured, whether or not under the Finance Documents. The execution of any other Finance Document shall not modify or supersede the security interest or any rights or obligations contained in this Agreement and shall not in any way affect, impair or invalidate the effectiveness and validity of this Agreement or any term or condition hereof. The Pledgor hereby waives its right to plead or claim in any court that the 15 20 execution of any other Finance Document is a cause for extinguishing, invalidating, impairing or modifying the effectiveness and validity of this Agreement or any term or condition contained herein. The Collateral Agent shall be at liberty to accept further security from the Pledgor or from any third party and/or release such security without notifying the Pledgor and without affecting in any way the obligations of the Pledgor under the Finance Documents. The Collateral Agent, upon written directions from the Secured Parties pursuant to the Intercreditor Agreement, or as otherwise expressly provided herein, shall determine if any security conferred upon the Collateral Agent under the Finance Documents shall be enforced by the Collateral Agent, as well as the sequence of securities to be so enforced. Section 6.6 Amendments. No waiver, amendment, modification or termination of any provision of this Agreement, or consent to any departure by the Pledgor therefrom, shall in any event be effective without the prior written consent of the Collateral Agent, acting upon written directions from the Secured Parties pursuant to the Intercreditor Agreement, or as otherwise expressly provided herein, and none of the Pledged Collateral shall be released without the written consent of the Collateral Agent, acting upon directions from the Secured Parties pursuant to the Intercreditor Agreement, or as otherwise expressly provided herein. Any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. Section 6.7 Successors and Assigns. This Agreement shall be binding upon the Pledgor and its successors and assigns and shall inure to the benefit of the Collateral Agent and the other Secured Parties and their respective successors and assigns. The Pledgor may not assign or otherwise transfer any of its rights or obligations under this Agreement without the written consent of the Collateral Agent, acting upon written directions from the Secured Parties pursuant to the Intercreditor Agreement, or as otherwise expressly provided herein. Section 6.8 Third Party Beneficiaries. The agreements of the parties hereto are intended to benefit the Secured Parties and their respective successors and assigns. Section 6.9 Conflict with Indenture. In case of a conflict between any provision of this Agreement and any provision of the Indenture, the provisions of the Indenture shall control and govern. No such conflict shall be deemed to exist thereby because this Agreement imposes greater obligations on the Subsidiary Guarantor or the Pledgor than the Indenture. 16 21 Section 6.10 Survival. All agreements, statements, representations and warranties made by the Pledgor herein or in any certificate or other instrument delivered by the Pledgor or on its behalf under this Agreement shall be considered to have been relied upon by the Collateral Agent and the other Secured Parties and shall survive the execution and delivery of this Agreement and the other Finance Documents until termination thereof or the indefeasible payment in full in cash or cash equivalents of all of the Secured Obligations and the termination of all commitments of the Secured Parties under the Finance Documents regardless of any investigation made by the Collateral Agent or the other Secured Parties or made on their behalf. Section 6.11 No Waiver; Remedies Cumulative. No failure or delay on the part of the Collateral Agent in exercising any right, power or privilege hereunder and no course of dealing between the Pledgor and the Collateral Agent shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies herein expressly provided are cumulative and not exclusive of any rights or remedies which the Collateral Agent would otherwise have. Section 6.12 Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. Section 6.13 Headings Descriptive. The headings of the several Sections and subsections of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement. Section 6.14 Severability. In case any provision contained in or obligation under this Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby. Section 6.15 Governing Law; Submission to Jurisdiction; Waiver of Jury Trial.

If for any reason such designee, appointee and agent shall cease to be available to act as such agent, the Pledgor agrees to designate a new designee, appointee and agent in New York City on the terms and for the purposes of this provision satisfactory to the Collateral Agent. The Pledgor further irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to the Pledgor at its address referred to in Section 6.1, such service to become effective thirty (30) days after such mailing. Nothing herein shall affect the right of the Collateral Agent or any other Person to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Pledgor in any other jurisdiction. (c) The Pledgor hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Agreement in the courts referred to in clause (b) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. 18 23 (d) WITH REGARD TO THIS AGREEMENT, EACH PARTY HERETO HEREBY WAIVES THE RIGHT TO A TRIAL BY JURY.
