9. Remedies upon Default. Upon the occurrence and during the continuance of an Event of Default:

(a) The Collateral Agent shall have the right to 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 of a secured party under the UCC (irrespective of whether the UCC applies to the affected items of the Pledged Collateral), and the Collateral Agent shall have the right, also without notice (except as specified below), to sell the Pledged Collateral or any part thereof in one or more parcels at a public or private sale, at any exchange, broker’s board or at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, at such time or times and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable, irrespective of the impact of any such sales on the market price of the Pledged Collateral. To the maximum extent permitted by applicable law, the Collateral Agent may be the purchaser of any or all of the Pledged Collateral at any such sale and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Pledged Collateral sold at any such

public sale, to use and apply all or any part of the Secured Obligations as a credit on account of the purchase price of any Pledged Collateral payable at such sale. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Pledgor, and each Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay, or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. Each Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten (10) calendar days notice to such Pledgor of the time and place of any public sale or the time after which a private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of the 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. To the maximum extent permitted by law, each Pledgor hereby waives any claims against the Collateral Agent arising because the price at which any Pledged Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Pledged Collateral to more than one offeree.

(b) Each Pledgor hereby agrees that any sale or other disposition of the Pledged Collateral conducted in conformity with reasonable commercial practices of banks, insurance companies, or other financial institutions in the County of New York, State of New York regularly employed in disposing of property similar to the Pledged Collateral shall be deemed to be commercially reasonable.

(c) Each Pledgor hereby acknowledges that the sale by the Collateral Agent of any Pledged Collateral pursuant to the terms hereof in compliance with the Securities Act as now in effect or as hereafter amended, or any similar statute hereafter adopted with similar purpose or effect, as well as applicable “Blue Sky” or other state securities laws may require strict limitations as to the manner in which the Collateral Agent or any subsequent transferee of the Pledged Collateral may dispose thereof. Each Pledgor acknowledges and agrees that in order to protect the Collateral Agent’s interest it may be necessary to sell the Pledged Collateral at a price less than the maximum price attainable if a sale were delayed or were made in another manner, such as a public offering under the Securities Act. Each Pledgor has no objection to a sale made in such a manner and agrees that the Collateral Agent and the other Secured Creditors shall have no obligation to obtain the maximum possible price for the Pledged Collateral. Without limiting the generality of the foregoing, each Pledgor agrees that, upon the occurrence and during the continuation of an Event of Default, the Collateral Agent may, subject to applicable law, from time to time attempt to sell all or any part of the Pledged Collateral by a private placement, restricting the bidders and prospective purchasers to those who will represent and agree that they are purchasing for investment only and not for distribution. In so doing, the Collateral Agent may solicit offers to buy the Pledged Collateral or any part thereof for cash, from a limited number of investors deemed by the Collateral Agent, in its reasonable judgment, to be institutional investors or other responsible and eligible parties who might be interested in purchasing the Pledged Collateral. If the Collateral Agent shall solicit such offers, then the acceptance by the Collateral Agent of one of the offers shall be deemed to be a commercially reasonable method of disposition of the Pledged Collateral.

(d) If the Collateral Agent shall determine to exercise its right to sell all or any portion of the Pledged Collateral pursuant to this Section, each Pledgor agrees that, upon request of the Collateral Agent, such Pledgor will, at its own expense:

(i) use its best efforts to execute and deliver, and cause the Issuer and the directors and officers thereof to execute and deliver, all such instruments and documents, and to do or cause to be done all such other acts and things, as may be reasonably necessary, or in the opinion of the Collateral Agent, reasonably advisable to register such Pledged Collateral under the provisions of the Securities Act, and to cause the registration statement relating thereto to become effective and to remain effective for such period as prospectuses are required by law to be furnished, and to make all amendments and supplements thereto and to the related prospectuses which, in the opinion of the Collateral Agent, are reasonably necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto;

(ii) use its best efforts to qualify the Pledged Collateral under the state securities laws or “Blue Sky” laws and to obtain all reasonably necessary governmental approvals for the sale of the Pledged Collateral, as requested by the Collateral Agent;

(iii) execute and deliver, or cause the officers and directors of the Issuer to execute and deliver, to any person, entity or Governmental Authority as the Collateral Agent may deem reasonably necessary or appropriate, any and all documents and writings which, in the Collateral Agent’s reasonable judgment, may be necessary for approval, or be required by, any regulatory authority located in any city, county, state or country where any Pledgor or Issuer engage in business, in order to transfer or to more effectively transfer the Pledged Interests or otherwise enforce the Collateral Agent’s rights hereunder; and

(iv) do or cause to be done all such other acts and things as may be necessary to make such sale of the Pledged Collateral or any part thereof valid and binding and in compliance with applicable law.

Each Pledgor acknowledges that there is no adequate remedy at law for failure by it to comply with the provisions of this Section and that such failure would not be adequately compensable in damages, and therefore agrees that its agreements contained in this Section may be specifically enforced.

(e) EACH PLEDGOR EXPRESSLY WAIVES TO THE MAXIMUM EXTENT PERMITTED BY LAW: (i) ANY CONSTITUTIONAL OR OTHER RIGHT TO A JUDICIAL HEARING PRIOR TO THE TIME THE COLLATERAL AGENT DISPOSES OF ALL OR ANY PART OF THE PLEDGED COLLATERAL AS PROVIDED IN THIS SECTION; (ii) ALL RIGHTS OF REDEMPTION, STAY, OR APPRAISAL THAT IT NOW HAS OR MAY AT ANY TIME IN THE FUTURE HAVE UNDER ANY RULE OF LAW OR STATUTE NOW EXISTING OR HEREAFTER ENACTED; AND (iii) EXCEPT AS SET FORTH IN SUBSECTION (a) OF THIS SECTION, ANY REQUIREMENT OF NOTICE, DEMAND, OR ADVERTISEMENT FOR SALE.

10. Application of Proceeds. Upon the occurrence and during the continuance of an Event of Default, any cash held by the Collateral Agent as Pledged Collateral and all cash proceeds received by the Collateral Agent in respect of any sale of, collection from, or other realization upon all or any part of the Pledged Collateral pursuant to the exercise by the Collateral Agent of its remedies as a secured creditor as provided in Section 9 shall be applied from time to time by Collateral Agent as provided in Section 1.10 of the Credit Agreement.

11. Duties of the Collateral Agent. So long as the Collateral Agent complies with its obligations, if any, under the UCC and under this Agreement and the other Loan Documents, the Collateral Agent’s only duty shall be to deal with the Pledged Collateral in its possession in the same manner as the Collateral Agent deals with similar property for its own account, and otherwise shall not be liable or responsible for: (a) the safekeeping of the Pledged Collateral; (b) any loss or damage thereto occurring or arising in any manner or fashion from any cause; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person. All risk of loss, damage, or destruction of the Pledged Collateral shall be borne by the Pledgors. The powers conferred on the Collateral Agent hereunder are solely to protect its interests in the Pledged Collateral and shall not impose on it any duty to exercise such powers. Except as provided in the UCC, this Agreement and the other Loan Documents, the Collateral Agent shall not have any duty with respect to the Pledged Collateral or any responsibility for taking any necessary steps to preserve rights against any Persons with respect to any Pledged Collateral. Nothing contained in this Section 11 or elsewhere in the Loan Documents shall relieve the Collateral Agent of liability or responsibility for its own gross negligence or willful misconduct.

12. GOVERNING LAW.

THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK.

13. CONSENT TO JURISDICTION, SERVICE OF PROCESS AND VENUE.

ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT MAY BE BROUGHT IN XXX XXXXXX XX XXX XXXXX XX XXX XXXX IN THE COUNTY OF NEW YORK OR OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PLEDGOR HEREBY IRREVOCABLY ACCEPTS IN RESPECT OF ITS PLEDGED COLLATERAL, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PLEDGOR HEREBY IRREVOCABLY CONSENTS TO THE SERVICE OF ANY AND ALL LEGAL PROCESS, SUMMONS, NOTICES, AND DOCUMENTS IN ANY SUIT, ACTION, OR PROCEEDING BROUGHT IN THE UNITED STATES OF AMERICA ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT BY THE MAILING (BY REGISTERED MAIL OR CERTIFIED MAIL, POSTAGE PREPAID) OR DELIVERING OF A COPY OF SUCH PROCESS TO SUCH PLEDGOR, X/X XXX XXXXXXXX XXXXXXXXXXXXXX, XX THE BORROWER REPRESENTATIVE’S ADDRESS FOR NOTICES AS SET FORTH IN THE CREDIT

AGREEMENT. EACH PLEDGOR 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 HEREIN SHALL AFFECT THE RIGHT OF THE SECURED CREDITORS TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY PLEDGOR IN ANY OTHER JURISDICTION. EACH PLEDGOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE JURISDICTION OR LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT PLEDGOR HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PLEDGED COLLATERAL, SUCH PLEDGOR HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT.

14. WAIVER OF JURY TRIAL, ETC.

EACH PLEDGOR AND THE COLLATERAL AGENT HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM CONCERNING ANY RIGHTS UNDER THIS AGREEMENT, OR UNDER ANY AMENDMENT, WAIVER, CONSENT, INSTRUMENT, DOCUMENT OR OTHER AGREEMENT DELIVERED OR WHICH IN THE FUTURE MAY BE DELIVERED IN CONNECTION HEREWITH, OR ARISING FROM ANY FINANCING RELATIONSHIP EXISTING IN CONNECTION WITH THIS AGREEMENT, AND AGREES THAT ANY SUCH ACTION, PROCEEDINGS OR COUNTERCLAIM SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. EACH PLEDGOR CERTIFIES THAT NO OFFICER, REPRESENTATIVE, AGENT OR ATTORNEY OF ANY AGENT OR ANY LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT ANY AGENT OR ANY LENDER WOULD NOT, IN THE EVENT OF ANY ACTION, PROCEEDING OR COUNTERCLAIM, SEEK TO ENFORCE THE FOREGOING WAIVERS. EACH PLEDGOR HEREBY ACKNOWLEDGES THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE SECURED CREDITORS, ENTERING INTO THIS AGREEMENT.

15. Entire Agreement, Amendments; Etc. This Agreement, together with the other Loan Documents, reflects the entire understanding of the parties with respect to the transactions contemplated hereby and shall not be contradicted or qualified by any other agreement, oral or written, before the date hereof. Neither this Agreement nor any provision hereof may be modified, amended or waived except by the written agreement of the parties to this Agreement. The foregoing notwithstanding, the Collateral Agent may re-execute this Agreement, modify, amend or supplement the Schedules hereto or execute a supplemental Pledge Agreement, as

provided herein, and the terms of any such modification, amendment, supplement or supplemental Pledge Agreement shall be deemed to be incorporated herein by this reference.

16. No Waiver; Remedies, Etc. No failure on the part of the Collateral Agent or any other Secured Creditor to exercise, and no delay in exercising, any right hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right under any Loan Document preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of the Secured Creditors and in the other Loan Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights of the Secured Creditors under any Loan Document against any party thereto are not conditional or contingent on any attempt by the Secured Creditors to exercise any of their rights under any other Loan Document against such party or against any other Person.

All notices and other communications hereunder to the Collateral Agent shall be in writing and shall be mailed, sent or delivered in accordance with the Credit Agreement and all notices and other communications hereunder to any Pledgor shall be in writing and shall be mailed, sent or delivered in care of the Borrower Representative in accordance with the Credit Agreement.

18. Security Interest Absolute. To the maximum extent permitted by law, all rights of the Collateral Agent, all security interests hereunder, and all obligations of the Pledgors hereunder, shall be absolute and unconditional, irrespective of:

(a) any lack of validity or enforceability of any of the Secured Obligations or any other agreement or instrument relating thereto, including any of the Loan Documents, any change in the time, manner, or place of payment of, or in any other term of, all or any of the Secured Obligations, or any other amendment or waiver of or any consent to any departure from any of the Loan Documents or any other agreement or instrument relating thereto;

(b) any exchange, release, or non-perfection of any other Pledged Collateral, or any release or amendment or waiver of or consent to departure from any Loan Document; or

Notwithstanding the foregoing, no Pledgor waives any defense or discharge available to it as a primary obligor, it being understood that the foregoing waivers are made by each Pledgor only in its capacity as a surety or other guarantor of the Secured Obligations.

19. Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

20. Counterparts; Telefacsimile Execution. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and all of which together shall

constitute one and the same Agreement. Delivery of an executed counterpart of this Agreement by telefacsimile shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telefacsimile also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, or binding effect hereof.

21. Waiver of Marshaling. Each Pledgor and the Collateral Agent acknowledges and agrees that in exercising any rights under or with respect to the Pledged Collateral: (a) the Collateral Agent is not under any obligation to marshal any Pledged Collateral; (b) the Collateral Agent may, in its absolute discretion, realize upon the Pledged Collateral in any order and in any manner it so elects (subject to any manner of realization or application otherwise required by the Loan Documents; and (c) the Collateral Agent may, subject solely to Section 10 hereof, apply the proceeds of any or all of the Pledged Collateral to the Secured Obligations in any order and in any manner it so elects (subject to any manner or order of application otherwise required by the Loan Documents). Each Pledgor and the Collateral Agent waives any right to require the marshaling of any of the Pledged Collateral.

22. Termination; Release. Subject to Section 24, when the Secured Obligations have been indefeasibly paid and performed in full in immediately available funds (other than contingent indemnification obligations to the extent no claim giving rise thereto has been asserted), including the cash collateralization, expiration, or cancellation of all Secured Obligations, if any, consisting of Letter of Credit Obligations, and the Commitments shall have expired or been irrevocably terminated, this Agreement shall terminate and all rights in the Pledged Collateral shall revert to the Pledgors. The Collateral Agent, at the request and sole expense of the Pledgors, will promptly execute and deliver to the Debtors the necessary instruments (including Uniform Commercial Code termination statements) acknowledging the termination of this Agreement, and will duly assign, transfer and deliver to the Debtors, without recourse, representation or warranty of any kind whatsoever, such of the Pledged Collateral as may be in possession of the Collateral Agent and has not theretofore been disposed of, applied or released.

23. Interpretation. Neither this Agreement nor any uncertainty or ambiguity herein shall be construed or resolved against the Collateral Agent or the other Secured Creditors, whether under any rule of construction or otherwise. On the contrary, this Agreement has been reviewed by all parties and shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of all parties hereto.

24. Reinstatement; Certain Payments. If any claim is ever made upon any Secured Creditor, for repayment or recovery of any amount or amounts received by such Secured Creditor, in payment or on account of any of the Secured Obligations, such Secured Creditor shall give prompt notice of such claim to each other Secured Creditor and the Pledgors, and if such Secured Creditor repays all or part of such amount by reason of (a) any judgment, decree or order of any court or administrative body having jurisdiction over such Secured Creditor, or any of its property or (b) any good faith settlement or compromise of any such claim effected by such Secured Creditor with any such claimant, then, each Pledgor agrees that (i) any such judgment, decree, order, settlement or compromise shall be binding upon it notwithstanding the cancellation of any Indebtedness hereunder or under the other Loan Documents or the

termination of this Agreement or the other Loan Documents, and (ii) it shall be and remain liable to such Secured Creditor hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by such Secured Creditor.
