(iv) Pledgor is the sole, legal and beneficial owner of the entire right, title and interest in and to the Pledged Collateral free and clear of any Lien, charge, covenant or any other adverse claim, except for the security interest held by the Revolving Credit Claimholders (as defined in the Intercreditor Agreement) until the Discharge of Revolving Credit Obligations (as defined in the Intercreditor Agreement).

If Collateral Agent shall determine to exercise its right to sell all or any of the Pledged Collateral pursuant to Section 10, Pledgor will, at Pledgor’s reasonable expense, do or cause to be done all such acts and things as may be necessary, or upon the request of Collateral Agent, as it deems to be necessary, or that Collateral Agent may request in its discretion exercised in good faith, to make any sale of the Pledged Collateral or any part thereof valid and binding and in compliance with applicable law.

5. VOTING RIGHTS; DIVIDENDS.

5.1 Absence of an Event of Default. So long as no Event of Default shall have occurred and be continuing:

(i) Pledgor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Pledged Collateral or any part thereof for any purpose not inconsistent with the terms of this Agreement, the Indenture or the other Indenture Documents; provided, however, that Pledgor shall not exercise (or refrain from exercising) any such right if such action would have an material and adverse effect on the value of the Pledged Collateral or any part thereof.

(ii) Pledgor shall be entitled, in the manner and to the extent permitted by the Indenture, to receive and retain any and all dividends and interest paid in respect of the Pledged Collateral; provided, however, that any and all:

(a) dividends, distributions and interest paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Pledged Collateral; and

(b) cash paid, payable or otherwise distributed in respect of principal of, or in redemption of, or in exchange for, any Pledged Collateral (provided that this clause (b) shall not be deemed to prohibit the payments allowed in the manner and to the extent set forth in Section 10.18 of the Indenture)

shall be delivered to Collateral Agent, or such nominee(s) of Collateral Agent as Collateral Agent shall direct, to hold as Pledged Collateral and shall, if received by Pledgor, be received in trust for the benefit of Collateral Agent, be segregated from the other property or funds of Pledgor, and be forthwith delivered to Collateral Agent, or such nominee(s) of Collateral Agent as Collateral Agent shall direct, as Pledged Collateral in the same form as so received (with any necessary indorsement(s)). Pledgor shall promptly execute such instruments, documents and agreements and do such acts as reasonably necessary, or as Collateral Agent may deem to be necessary or desirable to give effect to the provisions of this Section 5.1(ii).

5.2 Occurrence of an Event of Default. Upon the occurrence and during the continuance of an Event of Default, all rights of Pledgor to exercise the voting and other

-5-

consensual rights which it would otherwise be entitled to exercise pursuant to Section 5.1(i) and to receive the dividends and interest payments which it would otherwise be authorized to receive and retain pursuant to Section 5.1(ii) shall cease, at Collateral Agent’s election, and all such rights shall thereupon become vested in Collateral Agent, or such nominee(s) of Collateral Agent as Collateral Agent shall direct, who shall thereupon have the sole right (but not the obligation) to exercise such voting and other consensual rights and to receive and hold as Pledged Collateral such dividends and interest payments.

5.3 Dividends Received in Contravention of Agreement.

6. TRANSFERS AND OTHER LIENS; ADDITIONAL SHARES.

6.1 Transfers/Liens by Pledgor. Pledgor will not (i) sell, transfer, or otherwise dispose of, or grant any option or warrants, or rights to purchase with respect to, or permit any Person to be registered as holder of, any of the Pledged Collateral except in accordance with the exercise of Collateral Agent’s rights hereunder; (ii) create or permit to exist any Lien, charge or other encumbrance upon or with respect to any of the Pledged Collateral, except for the Lien created under this Agreement; or (iii) do, cause to be done or permit anything which may in any way have a material and adverse effect on the value of the Pledged Collateral.

6.2 Transfers by Subsidiary. Pledgor will not permit Subsidiary to issue any shares or other securities in addition to, or in exchange or substitution for, the Pledged Shares, except as permitted by the Indenture Documents.

7. POWER OF ATTORNEY. Pledgor irrevocably appoints the Collateral Agent and each and every Person to whom Collateral Agent shall from time to time have delegated in good faith the exercise of the power of attorney conferred by this Section 7, jointly and severally to be its attorney or attorneys and in its name and otherwise on its behalf to do all acts and things and to sign, seal, execute, deliver, perfect and do all deeds, instruments, documents, acts and things which may be required (or which Collateral Agent shall consider requisite) to perfect, protect or maintain its security interest in the Pledged Collateral or carry out any obligation imposed on Pledgor by or pursuant to this Agreement (including the obligations of Pledgor under Section 4) and enable Collateral Agent to exercise the powers conferred on it by or pursuant to this Agreement or by law. Collateral Agent shall have full power to delegate the power conferred on it by this Section 7 in Collateral Agent’s good faith judgment, but no such delegation shall preclude the subsequent exercise of such power by Collateral Agent itself or preclude Collateral Agent from making a subsequent delegation thereof to some other Person; any such delegation may be revoked by Collateral Agent at any time.

8. AGENT MAY PERFORM. If Pledgor fails to perform any of its obligations contained herein, Collateral Agent may (but shall not be obligated to), in the exercise of its discretion

-6-

exercised in good faith, itself perform, or cause performance of, such obligation, and the expenses of Collateral Agent incurred in connection therewith shall be payable by Pledgor under Section 11.2.

9. AGENT’S DUTIES. The powers conferred on Collateral Agent hereunder are solely to protect its interest in the Pledged Collateral and shall not impose any duty upon Collateral Agent to exercise any such powers. Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Pledged Collateral in its possession if the Pledged Collateral is accorded treatment substantially equal to that which Collateral Agent accords its own property, it being understood that Collateral Agent shall not have responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Pledged Collateral, whether Collateral Agent has or is deemed to have knowledge of such matters, or (ii) taking any necessary steps to preserve rights against any parties with respect to any Pledged Collateral. In acting under or by virtue of this Agreement, Collateral Agent shall be entitled to all the rights, privileges and protections provided to it in the Indenture, which are incorporated by reference herein mutatis mutandis. Collateral Agent hereby disclaims any representation or warranty to the other Secured Creditors or any other holders of the Obligations concerning the perfection of the liens and security interests granted hereunder or in the value or sufficiency of any of the Pledged Collateral. Collateral Agent shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office.

10. REMEDIES UPON AN EVENT OF DEFAULT.

10.1 Transfers by Collateral Agent. If any Event of Default shall have occurred and be continuing:

(i) Subject to the notice required to be given to Pledgor as specified below, Collateral Agent, at its option and without any obligation to do so, may transfer to or register in its name, or the name of any nominee(s) all or any part of the Pledged Collateral, and Collateral Agent may exercise in respect of the Pledged Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies under applicable law and of a secured party on default under the UCC; and, subject to the notice required to be given to Pledgor as specified below, Collateral Agent may also, without notice except as specified below, sell (through agents or otherwise) the Pledged Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or any of Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other commercially reasonable terms as Collateral Agent may determine in its good faith judgment. Collateral Agent shall be authorized at any such sale (if it deems it advisable to do so in its good faith judgment) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing the Pledged Shares for their own account in compliance with Regulation D of the Securities Act or under applicable law or under any other applicable exemption available under applicable law. Pledgor agrees that at least ten (10) Business Days notice to 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. Collateral Agent shall not be obligated to make any sale of the Pledged Collateral regardless of notice of sale having been given.

-7-

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; and

(ii) All cash proceeds received by Collateral Agent in respect of any sale of, collection from, or other realization upon all or any part of the Pledged Collateral may, in the discretion of Collateral Agent exercised in good faith, be held by Collateral Agent as Collateral for, or upon the occurrence and continuance of an Event of Default in whole or in part by Collateral Agent against, all or any parts of the Obligations in such order as provided by the Indenture. Any surplus of such cash or cash proceeds held by Collateral Agent and remaining after payment in full of all of the Obligations shall be paid over to Pledgor or to whomsoever may be lawfully entitled to receive such surplus.

10.2 Commercially Reasonable Disposition. Without precluding any other methods of sale, the sale of the Pledged Collateral, or any part thereof, shall have been made in a commercially reasonable manner if conducted in conformity with reasonable commercial practices of banks or finance companies disposing of similar property, but in any event, Collateral Agent may sell or otherwise dispose of the Pledged Collateral without assuming any credit risk and without any obligation to advertise.

10.3 Securities Laws. Pledgor recognizes that federal and/or state securities and other laws may limit the flexibility desired to achieve an otherwise commercially reasonable disposition of the Pledged Collateral, and in the event of potential conflict between such laws or regulations and what in other circumstances might constitute commercial reasonableness, compliance with such laws and regulations will prevail over attempts to achieve such commercial reasonableness. In connection with any sale or other disposition of the Pledged Collateral, compliance by Collateral Agent concerning the potential effect of any such law or regulation shall not be cause for Pledgor, or any other Person, to claim that such sale or other disposition was not commercially reasonable, it being the intent of Pledgor that Collateral Agent not be obligated to risk contravening any such law or regulation in order to effect what, but for such law or regulation, would be a commercially reasonable disposition.

10.4 Examples of Commercially Reasonable Disposition. By way of example and not by way of limitation, with respect to any sale or other disposition of the Pledged Collateral or any portion thereof: (i) such sale or disposition shall be commercially reasonable if made by and through a licensed broker/dealer acting under instructions to obtain in its good faith judgment the best disposition price known to it on the market (however, this provision does not suggest that such disposition is either preferable or exclusive); (ii) such sale or disposition shall be deemed to have been at a public sale if, in connection with such sale or disposition, Collateral Agent obtains bids from at least two qualified purchasers; and (iii) the net book value reflected on Pledgor’s most recent financial statements, adjusted to the date of any such sale or other disposition, is deemed to be a commercially reasonable price (but a price less than such net book value is not, of itself, deemed to be commercially unreasonable).

10.5 Pledgor Waivers. To the extent permitted by applicable law, and except as otherwise expressly provided under this Agreement or otherwise, Pledgor hereby waives all

-8-

rights now or hereafter conferred by statute or otherwise which may require Collateral Agent to give any notice, make any demand, or invoke any legal process with respect to the sale or other disposition of the Pledged Collateral or which may require Collateral Agent to sell or otherwise dispose of the Pledged Collateral in mitigation of Collateral Agent’s damages or which may otherwise limit or modify any of Collateral Agent’s remedies or rights under this Agreement.

10.6 No Duty Upon Collateral Agent. Collateral Agent shall be under no duty to sell or otherwise realize upon the Pledged Collateral. At any time, Collateral Agent may release or surrender all or any part of the Pledged Collateral to Pledgor.

11. INDEMNIFICATION; EXPENSES.

11.1 Indemnification. In consideration of the execution and delivery of the Indenture and the purchase of the Notes from Pledgor, Pledgor will indemnify and hold Secured Creditors and each Secured Creditors’ officers, directors, Affiliates, and agents (for the purposes of this Section 11.1 each is an “Indemnified Party”) harmless from and against any and all claims, losses, obligations and liabilities arising out of or resulting from any or all of (i) this Agreement, (ii) the transactions contemplated by this Agreement (including enforcement of this Agreement), and (iii) the Pledged Collateral except for claims, losses or liabilities to the extent resulting from an Indemnified Party’s bad faith, gross negligence or willful misconduct. The indemnification provided for in this Section 11.1 is in addition to, and not in limitation of, any other indemnification or insurance provided by Pledgor to Collateral Agent pursuant to any other Indenture Document.

11.2 Expenses. Pledgor will upon demand pay to Collateral Agent the amount of any and all reasonable expenses, including reasonable attorneys’ fees, which Collateral Agent may incur in connection with any and all of the following (i) the administration of this Agreement; (ii) the custody or preservation of, or the sale of, collection from or other realization upon any of the Pledged Collateral; (iii) the exercise or enforcement of any of the rights of Collateral Agent; or (iv) the failure by Pledgor to perform or observe any of the provisions of this Agreement, all of which constitute part of the Obligations and are secured by the Pledged Collateral.

12. SECURITY INTEREST ABSOLUTE. All rights of Collateral Agent and the security interest hereunder, and all obligations of Pledgor hereunder, shall be absolute and unconditional irrespective of:

(i) any invalidity or unenforceability in whole or in part of the Indenture or any other Indenture Document;

(ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Indenture Documents;

(iii) any exchange, release or non-perfection of any Note Collateral, or any release or amendment or waiver of or consent to departure from any guaranty for all or any of the Obligations; or

-9-

(iv) any other circumstance which might otherwise constitute a defense available to, or discharge of, Pledgor or a third party pledgor.

13. UNIMPAIRED SECURITY INTEREST. Any and all of Collateral Agent’s rights with respect to the Pledged Collateral and the security interest granted hereunder shall continue unimpaired until the payment and performance in full of the Obligations, notwithstanding the release or substitution at any time(s) of any of the Note Collateral, or of any rights or interest therein, or any delay, extension of time, renewal, compromise or other indulgence granted by Collateral Agent in reference to any of the Obligations. Pledgor hereby waives all notice of any such delay, extension, release, substitution, renewals, compromise or other indulgence, and hereby consents to be bound thereby as fully and effectively as if Pledgor had expressly agreed thereto in advance.

14. NOTICE. Any notice, certificate, request, notification and other communication required, permitted or contemplated hereunder must be in writing and given in accordance with the Indenture.

15. GENERAL.

15.1 Severability. If any term of this Agreement is found invalid under New York law or other laws of mandatory application by a court of competent jurisdiction, the invalid term will be considered excluded from this Agreement and will not invalidate the remaining terms of this Agreement.

15.2 GOVERNING LAW. THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED WHOLLY THEREIN, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

15.3 WAIVER OF JURISDICTION. AS A SPECIFICALLY BARGAINED INDUCEMENT FOR SECURED CREDITORS TO PURCHASE NOTES FROM PLEDGOR, PLEDGOR AND COLLATERAL AGENT AGREE THAT ANY ACTION, SUIT OR PROCEEDING IN RESPECT OF OR ARISING OUT OF THIS AGREEMENT, ITS VALIDITY OR PERFORMANCE, AND WITHOUT LIMITATION ON THE ABILITY OF SECURED CREDITORS, AND THEIR SUCCESSORS AND ASSIGNS, TO EXERCISE ALL RIGHTS AS TO THE PLEDGED COLLATERAL AND INITIATE AND PROSECUTE IN ANY APPLICABLE JURISDICTION ACTIONS RELATED TO REPAYMENT OF THE OBLIGATIONS, SHALL BE INITIATED AND PROSECUTED AS TO ALL PARTIES AND THEIR SUCCESSORS AND ASSIGNS AT NEW YORK, NEW YORK. SECURED CREDITORS AND PLEDGOR EACH CONSENTS TO AND SUBMITS TO THE NONEXCLUSIVE JURISDICTION OVER ITS PERSON BY ANY 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

-10-

APPELLATE COURT FROM ANY THEREOF HAVING JURISDICTION OVER THE SUBJECT MATTER, AND CONSENTS THAT ALL SERVICE OF PROCESS BE MADE BY CERTIFIED MAIL DIRECTED TO ISSUER AND SECURED CREDITORS AT THEIR RESPECTIVE ADDRESSES SET FORTH IN THE INDENTURE OR AS OTHERWISE PROVIDED UNDER THE LAWS OF THE STATE OF NEW YORK. PLEDGOR WAIVES ANY OBJECTION BASED ON FORUM NON CONVENIENS, AND ANY OBJECTION TO VENUE OF ANY ACTION INSTITUTED HEREUNDER, AND CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY THE COURT.

15.4 Survival and Continuation of Representations and Warranties. All of Pledgor’s representations and warranties contained in this Agreement shall (i) survive the execution, delivery and acceptance hereof by the parties hereto and the closing of the transactions described herein or related hereto and (ii) remain true until the Obligations are fully performed, paid and satisfied, made by Pledgor with the same effect as though the representations and warranties had been made again on, and as of, each day of the term of this Agreement (unless such representation and warranty refers to a specific date, then such representation and warranty shall be true as of such earlier date), subject to such changes as may not be prohibited hereby, do not constitute an Event of Default, and have been consented to by Collateral Agent in writing.

15.5 Additional Waivers by Pledgor. Pledgor waives presentment and protest of any instrument and notice thereof, and, except as expressly provided in the Indenture Documents, demand, notice of default and all other notices to which Pledgor might otherwise be entitled. Pledgor shall also assert no claim against Collateral Agent on any theory of liability for consequential, special, indirect or punitive damages except to the extent such claim arises from the gross negligence or willful misconduct of Collateral Agent.

15.6 Equitable Relief. Pledgor recognizes that, in the event Pledgor fails to perform, observe or discharge any of its obligations or liabilities under this Agreement, any remedy of law may prove to be inadequate relief to Collateral Agent; therefore, Pledgor agrees that Collateral Agent, if Collateral Agent so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

15.7 Cumulative Remedies. The remedies provided in this Agreement and the other Indenture Documents are cumulative and not exclusive of any remedies provided by law. Exercise of one or more remedy(ies) by Collateral Agent does not require that all or any other remedy(ies) be exercised and does not preclude later exercise of the same remedy.

15.8 Waivers and Amendments in Writing. Failure by Collateral Agent to exercise any right, remedy or option under this Agreement or delay by Collateral Agent in exercising the same shall not operate as a waiver by Collateral Agent of its right to exercise any such right, remedy or option. No waiver by Collateral Agent shall be effective unless it is in writing and signed by Collateral Agent, and then only to the extent specifically stated. This Agreement cannot be changed or terminated orally.

-11-

15.9 Entire Agreement; Counterparts; Fax Signatures. This Agreement sets forth the entire agreement of the parties with respect to subject matter of this Agreement and supersedes all previous understandings, written or oral, in respect thereof. Any request from time to time by Pledgor for Collateral Agent’s consent under any provision in this Agreement or any other Indenture Documents must be in writing, and any consent to be provided by Collateral Agent under this Agreement or any other Indenture Documents from time to time must be in writing in order to be binding on Collateral Agent; however, Collateral Agent will have no obligation to provide any consent requested by Pledgor, and Collateral Agent may, for any reason in its discretion exercised in good faith, elect to withhold the requested consent. Two or more duplicate originals of this Agreement may be signed by the parties, each of which shall be an original but all of which together shall constitute one and the same instrument. Any documents delivered by, or on behalf of, Pledgor by fax transmission or other electronic delivery of an image file reflecting the execution hereof (i) may be relied on by Collateral Agent as if the document were a manually signed original and (ii) will be binding on Pledgor for all purposes of this Agreement or any other Indenture Documents.

15.10 Recourse to Directors or Officers. The obligations of Collateral Agent under this Agreement are solely the corporate obligations of Collateral Agent. No recourse shall be had for the payment of any amount owing in respect to this Agreement or for the payment of any fee hereunder or for any other obligation or claim arising out of or based upon this Agreement against any stockholder, employee, officer, or director of Collateral Agent.

15.11 Assignment. Collateral Agent shall have the right to assign this Agreement. Pledgor may not assign, transfer or otherwise dispose of any of its rights or obligations hereunder, by operation of law or otherwise, except pursuant to a transaction permitted under Section 5.01 of the Indenture, and any such assignment, transfer or other disposition without Collateral Agent’s written consent (with the consent of the Holders or Trustee as specified in Sections 9.01 and 9.02 of the Indenture) shall be void. All of the rights, privileges, remedies and options given to Collateral Agent under this Agreement shall inure to the benefit of Collateral Agent’s successors and assigns, and all the terms, conditions, covenants, provisions and warranties herein shall inure to the benefit of and bind the permitted successors and assigns of Pledgor and Collateral Agent.

15.12 Headings. Section headings in this Agreement are included for convenience of reference only and shall not relate to the interpretation or construction of this Agreement.

15.13 Conflict.
