No effective financing statement or other instrument similar in effect covering all or any part of such Collateral or listing such Pledgor or any trade name of such Pledgor as debtor with respect to such Collateral is on file in any recording office, except such as may have been filed in favor of the Agent relating to the Loan Documents.

(d) To the extent applicable, the Pledged Equity pledged by such Pledgor hereunder has been duly authorized and validly issued and is fully paid and non-assessable.

(i) such Pledgor will file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Agent may request, in order to perfect and preserve the security interest in the Collateral granted or purported to be granted by such Pledgor hereunder;

(ii) such Pledgor will promptly execute and deliver, or otherwise authenticate, all further instruments and documents, and take all further action that may be necessary or desirable, and that the Agent may reasonably request, in order to perfect and protect any pledge or security interest granted or purported to be granted by such Pledgor hereunder or to enable the Agent to exercise and enforce its rights and remedies hereunder with respect to any Pledged Equity of such Pledgor. Without limiting the generality of the foregoing, each Pledgor will promptly with respect to Pledged Equity of such Pledgor: (A) deliver and pledge to the Agent for benefit of the Secured Parties certificates representing Security Collateral that constitutes certificated securities, accompanied by undated stock or bond powers executed in blank; provided, however, that such Pledgor shall have thirty days from the date hereof (or such longer period as may be agreed by the Agent) to deliver to the Agent certificates representing foreign Security Collateral that constitutes certificated securities; (B) take all action necessary to ensure that the Agent has control of Collateral consisting of investment property as provided in Section 9-106 of the UCC; and (C) deliver to the Agent evidence that all other action that the Agent may deem reasonably necessary or desirable in order to perfect and protect the security interest created by such Pledgor under this Agreement has been taken; and

(iii) if an Event of Default shall have occurred and be continuing, such Pledgor will promptly execute and deliver, or otherwise authenticate, all further instruments and documents, and take all further action that may be necessary or desirable, and that the Agent may reasonably request, in order to perfect and protect any pledge or security interest granted or purported to be granted by such Pledgor hereunder or to enable the Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral of such Pledgor (other than the Pledged Equity referred to in Section 7(a)(ii)). Without limiting the generality of the foregoing, each Pledgor will promptly with respect to Collateral of such Pledgor: (A) if any such Collateral shall be evidenced by a promissory note or other instrument, deliver and pledge to the Agent hereunder such note or instrument duly indorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance satisfactory to the Agent; (B) deliver and pledge to the Agent for benefit of the Secured Parties certificates representing Security Collateral that constitutes certificated securities, accompanied by undated stock or bond powers executed in blank; (C) take all action necessary to ensure that the Agent has control of Collateral consisting of investment property as provided in Section 9-106 of the UCC; and (D) deliver to the Agent evidence that all other action that the Agent may deem reasonably necessary or desirable in order to perfect and protect the security interest created by such Pledgor under this Agreement has been taken.

(b) Each Pledgor hereby authorizes the Agent to file one or more financing or continuation statements in any jurisdiction and with any filing office, each indicating the collateral that such financing statement covers (as described in Exhibit B hereto), and amendments thereto, in each case without the signature of such Pledgor, and regardless of whether any particular asset described in such financing statements falls within the scope of the UCC or the granting clause of this Agreement. A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. Each Pledgor ratifies its authorization for the Agent to have filed such financing statements, continuation statements or amendments filed prior to the date hereof.

(c) Each Pledgor will furnish to the Agent from time to time statements and schedules further identifying and describing the Collateral of such Pledgor and such other reports in connection with such Collateral as the Agent may reasonably request, all in reasonable detail.

No Pledgor will become bound by a security agreement relating to the Collateral that is authenticated by another Person (determined as provided in Section 9-203(d) of the UCC) without giving the Agent 15 days’ prior written notice thereof and taking all action reasonably required by the Agent to ensure that the perfection and first priority nature of the Agent’s security interest in the Collateral will be maintained. Each Pledgor will hold and preserve its records relating to the Collateral and will permit representatives of the Agent at any time during normal business hours to inspect and make abstracts from such records and other documents. If the Pledgor does not have an organizational identification number and later obtains one, it will forthwith notify the Agent of such organizational identification number.

Section 9. Voting Rights; Dividends; Etc.(a) So long as no Default under Section 6.01(e) of the Credit Agreement or an Event of Default shall have occurred and be continuing:

(i) Each Pledgor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Security Collateral of such Pledgor or any part thereof for any purpose; provided however, that such Pledgor will not exercise or refrain from exercising any such right if such action would have a material adverse effect on the value of the Security Collateral.

(ii) Each Pledgor shall be entitled to receive, retain and use any and all Dividends and other distributions paid in respect of the Security Collateral of such Pledgor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Loan Documents.

9

(iii) The Agent will execute and deliver (or cause to be executed and delivered) to each Pledgor all such proxies and other instruments as such Pledgor may reasonably request for the purpose of enabling such Pledgor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the Dividends or other payments that it is authorized to receive and retain pursuant to paragraph (ii) above.

(b) Upon the occurrence and during the continuance of a Default under Section 6.01(e) of the Credit Agreement or an Event of Default:

(i) All rights of each Pledgor (x) to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 9(a)(i) shall, upon notice to such Pledgor by the Agent, cease and (y) to receive the Dividends, interest and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 9(a)(ii) shall upon notice to such Pledgor by the Agent, cease, and all such rights shall thereupon become vested in the Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such Dividends, interest and other distributions.

(ii) All Dividends, interest and other distributions that are received by any Pledgor contrary to the provisions of paragraph (i) of this Section 9(b) shall be received in trust for the benefit of the Agent, shall be segregated from other funds of such Pledgor and shall be forthwith paid over to the Agent as Security Collateral in the same form as so received (with any necessary indorsement).

Section 10. Transfers and Other Liens; Additional Shares. (a) Each Pledgor agrees that it will not (i) sell, assign or otherwise dispose of any of the Collateral, other than sales, assignments and other dispositions of Collateral, and options relating to Collateral, not prohibited under the terms of the Loan Documents, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral of such Pledgor except for the pledge, assignment and security interest created under this Agreement or Permitted Liens.

(b) Each Pledgor agrees that it will (i) cause each issuer of the Pledged Equity pledged by such Pledgor not to issue any Equity Interests or other securities in addition to or in substitution for the Pledged Equity issued by such issuer, except to such Pledgor, and (ii) pledge hereunder, immediately upon its acquisition (directly or indirectly) thereof, any and all additional Equity Interests or other securities of each issuer of the Pledged Equity.

Section 11. Agent Appointed Attorney-in-Fact. Each Pledgor hereby irrevocably appoints the Agent such Pledgor’s attorney-in-fact, with full authority in the place and stead of such Pledgor and in the name of such Pledgor or otherwise, from time to time, if an Event of Default shall have occurred and be continuing, in the Agent’s discretion, to take any action and to execute any instrument that the Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation:

(c) to file any claims or take any action or institute any proceedings that the Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Agent with respect to any of the Collateral.

Section 12. Agent May Perform. If any Pledgor fails to perform any agreement contained herein, the Agent may, as the Agent deems necessary to protect the security interest granted hereunder in the Collateral or to protect the value thereof, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the Agent incurred in connection therewith shall be payable by such Pledgor under Section 14.

Section 13. Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Agent may exercise in respect of the 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 upon default under the UCC (whether or not the UCC applies to the affected Collateral) and also may: (i)  without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Agent may deem commercially reasonable; and (ii) exercise any and all rights and remedies of any of the Pledgors under or in connection with the Collateral, or otherwise in respect of the Collateral, including, without limitation, those set forth in Section 9-607 of the UCC. Each Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such 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 Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The 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.

(b) Any cash held by or on behalf of the Agent and all cash proceeds received by or on behalf of the Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Agent, be held by the Agent as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Agent pursuant to Section 14) in whole or in part by the Agent for the ratable benefit of the Secured Parties against, all or any part of the Secured Obligations, in the following manner:

11

(i) first, paid to the Agent for any amounts then owing to the Agent pursuant to the Loan Documents; and

(ii) second, an amount equal to the remaining outstanding Secured Obligations shall be paid to the Agent for the account of the Lenders.

(c) Any amounts due and payable to the Lenders pursuant to Section 13(b) shall be ratably (A) paid to the Lenders for any amounts then owing to them, in their capacities as such, under the Loan Documents ratably in accordance with such respective amounts then owing to such Lenders and (B) deposited as Collateral in the L/C Cash Deposit Account up to an amount equal to 100% of the aggregate Available Amount of all outstanding Letters of Credit in accordance with Section 6.02 of the Credit Agreement.

(d) For purposes of applying payments received in accordance with this Section 13, the Agent shall be entitled to rely upon the Agent for a determination of the outstanding Secured Obligations owed to the Lenders.

(e) All payments received by any Pledgor in respect of the Collateral shall be received in trust for the benefit of the Agent, shall be segregated from other funds of such Pledgor and shall be forthwith paid over to the Agent in the same form as so received (with any necessary indorsement).

(f) Notwithstanding anything to the contrary herein, this Agreement may be enforced only by the action of the Agent acting upon the instructions of the Required Lenders and no other Lender shall have any right individually to seek to enforce or to enforce this Agreement or to realize upon the security to be granted hereby, it being understood and agreed that such rights and remedies may be exercised by the Agent or the holders of at least a majority of the outstanding other Secured Obligations, as the case may be, for the benefit of the Lenders upon the terms of this Agreement.

Section 14. Indemnity and Expenses. (a) Each Pledgor agrees to indemnify, defend and save and hold harmless each Secured Party and each of their Affiliates and their respective officers, directors, employees, agents and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Agreement (including, without limitation, enforcement of this Agreement), except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct.

12

(b) Each Pledgor will upon demand pay to the Agent the amount of any and all reasonable expenses, including, without limitation, the reasonable fees and expenses of its counsel and of any experts and agents, that the Agent may incur in connection with (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 Collateral of such Pledgor, (iii) the exercise or enforcement of any of the rights of the Agent or the other Secured Parties hereunder or (iv) the failure by such Pledgor to perform or observe any of the provisions hereof.

Section 15. Amendments; Waivers; Additional Pledgors; Etc.(a) No amendment or waiver of any provision of this Agreement, and no consent to any departure by any Pledgor herefrom, shall in any event be effective unless the same shall be in writing and signed by the Agent (and, in the case of any amendment of any provision of this Agreement, each Pledgor), and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure on the part of the Agent or any other Secured Party to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right.

(b) Upon the execution and delivery, or authentication, by any Person of a pledge agreement supplement in substantially the form of Exhibit A hereto (each a “Pledge Agreement Supplement”), (i) such Person shall be referred to as an “Additional Pledgor” and shall be and become a Pledgor hereunder, and each reference in this Agreement and the other Loan Documents to “Pledgor” shall also mean and be a reference to such Additional Pledgor, and each reference in this Agreement and the other Loan Documents to “Collateral” shall also mean and be a reference to the Collateral of such Additional Pledgor, and (ii) the supplemental schedules I-III attached to each Pledge Agreement Supplement shall be incorporated into and become a part of and supplement Schedules I-III, respectively, hereto, and the Agent may attach such supplemental schedules to such Schedules; and each reference to such Schedules shall mean and be a reference to such Schedules as supplemented pursuant to each Pledge Agreement Supplement.
