occurrence and during the continuance of any Event of Default, the Collateral Agent will have the right at any time in its sole discretion and without notice to Pledgor to transfer to or to register in the name of the Collateral Agent or its nominees any or all of the Collateral, subject only to the revocable rights specified in Section 7(a) and compliance with ACC Regulations.

Notwithstanding the foregoing, any account control agreement which requires the Collateral Agent in its individual capacity to indemnify the depository or other institution other than out of the Collateral will not be reasonably satisfactory to the Collateral Agent.

(b)Subject to Section 2(d), Pledgor covenants and agrees that upon declaration and payment of any dividend or distribution by any Subsidiary, it will cause such dividend or distribution to be paid and segregated into the Specified Account.

SECTION 5.REPRESENTATIONS, WARRANTIES AND CERTAIN COVENANTS. Pledgor represents, warrants and covenants as follows:

SECTION 6.FURTHER ASSURANCES. Pledgor authorizes the Collateral Agent to file any financing statements covering the Collateral or any part thereof as the Collateral Agent may desire. Pledgor agrees that from time to time, at the expense of Pledgor, Pledgor will promptly execute and deliver all further documentation and take all further actions that the Collateral Agent or Holder may reasonably request, in order to perfect and protect any security interest granted or purported to be granted hereby or to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Pledgor will furnish to the Collateral Agent from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Collateral Agent or Holder may reasonably request, all in reasonable detail, Pledgor agrees, and agrees to cause each issuer of Equity Interests included in the Collateral, to mark its books and records to reflect the Lien of the Collateral Agent in the Collateral.

SECTION 7.VOTING AND DIVIDENDS.

(ii)Pledgor will be entitled to receive and retain any dividends or distributions paid in respect of the Collateral; provided however, except as expressly permitted by the Loan Agreement, any (A) dividends or distributions 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 Collateral, (B) dividends and other distributions paid or payable in cash in respect of any Collateral in connection with a partial or total liquidation or dissolution, and (C) cash paid, payable or otherwise distributed in redemption of, or in exchange for, any Collateral, shall be forthwith delivered to the Col1ateral Agent to hold as Collateral and shall, if received by Pledgor, be received in trust for the benefit of the Collateral Agent, be segregated from the other property or funds of Pledgor, and be forthwith delivered to the · Collateral Agent as Collateral in the same form as so received (with any necessary endorsement).

(iii)The Collateral Agent shall execute and deliver (or cause to be executed and delivered) to Pledgor all such proxies and other instruments as Pledgor may reasonably request for the purpose of enabling Pledgor to exercise the voting and other rights it is entitled to exercise pursuant to Section7(a)(i) and to receive dividends it is authorized to receive and retain pursuant to Section7(a)(ii).

(b)Subject to any requirements of ACC Regulations, on the occurrence and during the continuation of an Event of Default:

SECTION 8.REMEDIES. Subject to any requirements of ACC Regulations:

(a)The Collateral Agent may exercise in respect of any Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all rights and remedies of a secured party on default under the UCC (whether or not the UCC applies to the

affected Collateral), and the Collateral Agent may also, 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 exchange, broker’s board or at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and on such other terms as the Collateral Agent may claim commercially reasonable. Pledgor agrees that at least ten days’ notice to Pledgor of the time and place of any public sale or time after which any private sale is to be made will constitute reasonable notification. The Collateral Agent will not be obligated to make any sale of 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.

(b)Any cash held by the Collateral Agent as Collateral and all cash proceeds received by the Collateral Agent in respect of any sale of, collection from, or other realization on any Collateral shall be applied by the Collateral Agent against the Secured Obligations in such order as the Collateral Agent may elect, subject to the requirements of the Loan Agreement and Collateral Agency Agreement. Any surplus of such cash or cash proceeds held by the Collateral Agent and remaining after payment in full of all Secured Obligations and Notes shall be paid over to the Pledgor or to whomsoever may be lawfully entitled to receive such surplus.

(c)All rights and remedies of the Collateral Agent expressed herein are in addition to all other rights and remedies possessed by the Collateral Agent or the Holder in the Revolver Documents and any other agreement or instrument relating to the Secured Obligations.

(d)In connection with a public or private sale of any Collateral, the Collateral Agent may disclose to prospective purchasers any non-public information available to the Collateral Agent which pertains to: (i) the issuer of any Collateral; or (ii) Pledgor, provided in the case of Pledgor such non-public information is material to said issuer, its financial condition or the Collateral.

(e)Without in any way limiting the foregoing, on the occurrence and during the continuation of any Event of Default, the Collateral Agent shall have the right, in addition to all other rights provided herein or by Law, to direct the disposition of the funds in any Specified Account that is a deposit account, or entitlement orders originated by the secured party with respect to each such Specified Account that is a securities account, in each case without further consent by Pledgor.

(f)If the Collateral Agent exercises its right to take possession of any Collateral, Pledgor shall also at its expense perform any other steps requested by the Collateral Agent or Holder to preserve and protect the security interest hereby granted in the Collateral, such as maintaining Collateral records and filing UCC financing and continuation statements.

SECTION 9.WAIVERS; PRIVATE SALES.

(a)Pledgor waives any right to require the Collateral Agent or Holder to: (i) proceed against any Person, including any other Obligor; or (ii) proceed against or exhaust any Collateral, or (iii) pursue any other remedy in Collateral Agent’s or the Holder’s power; and

waives any defense arising by reason of any disability of Pledgor or any other Person. Until the Secured Obligations have been paid in full, Pledgor waives any right of subrogation, reimbursement, indemnification, and contribution (contractual, statutory or otherwise), including any right of subrogation under the Bankruptcy Code (Title 11, United States Code) or any successor statute, arising from the existence or performance of this Agreement, and Pledgor waives any right to enforce any remedy which the Collateral Agent now has or may hereafter have against Pledgor or any other Person, and waives any benefit of, and any right to participate in, any security now or hereafter held by the Collateral Agent. Pledgor authorizes the Collateral Agent, without notice or demand and without affecting Pledgor’s liability hereunder, from time to time to: (a) renew, compromise, extend, accelerate or otherwise change the time for payment of, or otherwise change the terms of, any Secured Obligations, including increase or decrease of any rate of interest thereon; (b) receive and hold security, other than the Collateral herein described, for the payment of any Secured Obligations, and exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any Collateral or other security; and (c) release or substitute the Company, or any other guarantors of such Secured Obligations or any part thereof, or any other parties thereto.

(b)Pledgor recognizes that the Collateral Agent may be unable to effect a public sale of any of the Collateral by reason of ACC Regulations and/or certain prohibitions contained in the Laws of any jurisdiction outside the United States or in the Securities Act and applicable state securities Laws, but may instead be compelled to resort to one or more private sales thereof to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such Collateral for their own account for investment and not with a view to the distribution or resale thereof, or otherwise in accordance with the ACC Regulations. Pledgor agrees that any private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall, to the extent permitted by Law, be made in a commercially reasonable manner. The Collateral Agent will not be under any obligation to delay a sale of any Collateral for the period of time necessary to permit the issuer of such securities to register such securities under the Laws of any jurisdiction outside the United States, under the Securities Act or under any applicable state securities Laws, even if the issuer would agree to do so. If the Collateral Agent is able to lawfully effect a public sale without registration of the Collateral under the laws of any jurisdiction outside the United States, under the 1933 Act or under any applicable state securities Laws, then, subject to any applicable ACC Regulations, the Collateral Agent may, but will not be required to, conduct a public sale of the Collateral, rather than a private sale, if the Collateral Agent reasonably believes it would realize a higher sales price in a public sale.

SECTION 10.COLLATERAL AGENT’S DUTIES.

(a)The powers conferred on the Collateral Agent hereunder are solely to protect the interests of the Secured Parties in the Collateral and shall not impose any duty on the Collateral Agent to exercise any such powers. Except for reasonable care in the custody of any Collateral in its possession and accounting for moneys actually received by it hereunder, the Collateral Agent will have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. The

Collateral Agent will have exercised reasonable care in the custody and preservation of Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property and collateral held for others in its capacity as a collateral agent, it being understood that the Collateral Agent will not have any responsibility for: (a) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not the Collateral Agent has or is deemed to have knowledge of such matters; or (b) taking any necessary steps to preserve rights against any parties with respect to any Collateral.

(b)Upon the appointment of a replacement collateral agent pursuant to the Collateral Agency Agreement, the Collateral Agent may transfer all of its interest and Liens in or any of the Collateral and be fully discharged thereafter from all liability and responsibility with respect to such Collateral so transferred, and the transferee shall be vested with all the rights and powers of the Collateral Agent hereunder with respect to such Collateral so transferred; but with respect to any of its interest and liens in Collateral not so transferred, the Collateral Agent will retain all rights and powers hereby given.

SECTION 11.OTHER RIGHTS.

(a)The rights, powers and remedies given to the Collateral Agent by this Agreement shall be in addition to all rights, powers and remedies given to the Collateral Agent by virtue of any statute or rule of Law. Any forbearance or failure or delay by the Collateral Agent in exercising any right, power or remedy hereunder shall not be a waiver of such right, power or remedy, and any single or partial exercise of any right, power or remedy hereunder shall not preclude the further exercise thereof; and every right, power and remedy of the Collateral Agent shall continue in full force and effect until such right, power or remedy is specifically waived by a writing executed by the Collateral Agent. The rights and remedies of the Collateral Agent under this Agreement shall be cumulative and not exclusive of any other right or remedy which the Collateral Agent or any Holder may have.

(b)This Agreement constitutes an assignment of rights only and not an assignment of any duties or obligations of Pledgor in any way related to the Collateral, and the Collateral Agent will have no duty or obligation to discharge any such duty or obligation. The Collateral Agent will have no responsibility for taking any necessary steps to preserve rights against any parties with respect to any Collateral or initiating any action to protect any Collateral against the possibility of a decline in market value. Neither the Collateral Agent nor any party acting as attorney for the Collateral Agent will be liable for any acts or omissions or for any error of judgment or mistake of fact or Law other than its gross negligence or willful misconduct or negligence in the handling of funds.

(c)In addition to any other powers of attorney contained herein, Pledgor hereby appoints the Collateral Agent, its nominee, and any other person whom the Collateral Agent may designate, as Pledgor’s attorney-in-fact, with full power and authority to sign Pledgor’s name on verifications of Collateral; to send requests for verification of Collateral to obligors; to endorse Pledgor’s name on any checks, notes, acceptances, money orders, drafts and other forms of payment or security that may come into the Collateral Agent’s possession or on

any assignments, stock powers or other instruments of transfer relating to any Collateral; to sign Pledgor’s name on claims to enforce collection of any Collateral, on notices to and drafts against obligors, on schedules and assignments of Collateral, on notices of assignment and on public records; on the occurrence and during the continuance of an Event of Default to notify post office authorities to change the address for delivery of Pledgor’s mail to an address designated by the Collateral Agent; upon the occurrence and during the continuance of an Event of Default to receive, open and dispose of all mail addressed to Pledgor; and to do all things necessary to carry out this Agreement. Pledgor hereby ratifies and approves all acts of any such attorney and agrees that neither the Collateral Agent nor any such attorney will be liable for any acts or omissions nor for any error of judgment or mistake of fact or Law other than such person’s gross negligence or willful misconduct or negligence in the handling of funds. The foregoing powers of attorney, being coupled with an interest, are irrevocable until the Secured Obligations have been fully paid and satisfied and all agreements of any Secured Party to extend credit to or for the account of Pledgor have expired or otherwise been terminated.

SECTION 12.INDEMNITY; WAIVER.

(a)Pledgor agrees to indemnify, pay and hold harmless, the Collateral Agent and each other Secured Party and any of their Related Parties (each an “Indemnitee”), from and against any and all Indemnified Liabilities, IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE OR CONTRIBUTORY NEGLIGENCE OF SUCH INDEMNITEE; provided, Pledgor shall not have any obligation to any Indemnitee hereunder with respect to any Indemnified Liabilities to the extent such Indemnified Liabilities (x) arise from the gross negligence or willful misconduct, as determined by a court of competent jurisdiction by final and nonappealable judgment, of that Indemnitee, or (y) result from a claim brought by Pledgor against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Revolver Document, as determined by a court of competent jurisdiction by final and nonappealable judgment. To the extent the undertakings to indemnify, pay and hold harmless in this Section 12 may be unenforceable in whole or in part because they are violative of any Law or public policy, Pledgor shall contribute the maximum portion it is permitted to pay and satisfy under applicable Laws to the payment and satisfaction of all Indemnified Liabilities incurred by any Indemnitees. All amounts due under this Section 12(a) shall be payable promptly after demand therefor. For purposes hereof, “Related Parties” means, with respect to any Person, such Person’s Affiliates and the partners, managers, directors, trustees, officers, employees or other personnel, counsel, agents and advisors of such Person and of such Person’s Affiliates.

(b)To the extent not prohibited by applicable Law, Pledgor shall not assert, and Pledgor waives, any claim against the Collateral Agent and its respective Related Parties, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) (whether or not the claim therefor is based on contract, tort or duty imposed by any applicable legal requirement) arising out of, in connection with, as a result of, or in any way related to, this Agreement or any other Revolver Document or any agreement or instrument contemplated hereby or thereby or referred to herein or therein, the transactions contemplated hereby or thereby, or the use of the proceeds thereof or any act or omission or
