Prior to the Discharge of First Lien Obligations: (a) Each Grantor will maintain deposit accounts and securities/deposit accounts only with the Depositary in accordance with the terms of the Security Deposit Agreement, with the financial institution acting as First Lien Collateral Agent hereunder or with a bank (a “Pledged Account Bank”) that has agreed with such Grantor and the First Lien Collateral Agent to comply with instructions originated by the First Lien Collateral Agent directing the disposition of funds in such deposit account or securities/deposit account without the further consent of such Grantor, such agreement to be in form and substance satisfactory to the First Lien Collateral Agent (a “Securities/Deposit Account Control Agreement”) provided that no Securities/Deposit Account Control Agreement shall be required in respect of any securities account or deposit account to the extent the amount on deposit in, or credited to, such account does not exceed $300,000. (b) Each Grantor will instruct each Pledged Account Bank to transfer to the Revenue Account, at the end of each Business Day, in same day funds, an amount equal

11 to the amount by which the credit balance of the Pledged Account at such Pledged Account Bank exceeds $500,000. If any Grantor shall fail to give any instructions to any Pledged Account Bank, the First Lien Collateral Agent may do so without further notice to any Grantor. (c) Each Grantor may draw checks on, and otherwise transfer or withdraw amounts from, the Pledged Accounts in such amounts as may be required in the ordinary course of business.

(e) From and after the occurrence of and during the continuance of a First Lien Event of Default, upon the request of the First Lien Collateral Agent, each Grantor agrees to terminate any or all Pledged Accounts and Securities/Deposit Account Control Agreements. (f) The First Lien Collateral Agent may, at any time and without notice to, or consent from, the Grantor, transfer, or direct the transfer of, funds from the Pledged Accounts to satisfy the Grantor’s obligations under the First Lien Documents if any payment default that is a First Lien Event of Default shall have occurred and be continuing.

In connection with such collections, such Grantor may take such action as such Grantor may deem necessary or advisable to enforce collection of the Assigned Agreements, Receivables and Related Contracts; provided, however, that the First Lien Collateral Agent shall have the right, upon the occurrence and during the continuance of a First Lien Event of Default and upon written notice to such Grantor of its intention to do so, to notify the Obligors under any Assigned Agreements, Receivables and Related Contracts of the assignment of such Assigned Agreements, Receivables and Related Contracts to the First Lien Collateral Agent and to direct such Obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to the First Lien Collateral Agent and, upon such notification and at the expense of such Grantor, to enforce collection of any such Assigned Agreements, Receivables and Related Contracts, to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done, and to otherwise exercise all rights with respect to such Assigned Agreements, Receivables and Related Contracts, including, without limitation, those set forth set forth in Section 9-607 of the UCC. After receipt by any Grantor of the notice from the First Lien Collateral Agent referred to in the proviso to the preceding sentence, (i) all amounts and proceeds (including, without limitation, instruments) received by such Grantor in respect of the Assigned Agreements, Receivables and Related Contracts of such Grantor shall be received in trust for the benefit of the First Lien Collateral Agent hereunder, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the First Lien Collateral Agent in the same form as so received (with any necessary indorsement) to be deposited in the Revenue Account for application in accordance with the Security Deposit Agreement and (ii) such Grantor will not adjust, settle or compromise the amount or payment of any Receivable or amount due on any Assigned Agreement or Related Contract, release wholly or partly any Obligor thereof or allow any credit or discount thereon.

(ii) Each Grantor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in respect of the Security Collateral of such Grantor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the First Lien Documents; provided, however, that any and all (A) dividends, interest and other 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 Security Collateral shall be, and shall be forthwith delivered to the First Lien Collateral Agent to hold as, Security Collateral and shall, if received by such Grantor, be received in trust for the benefit of the First Lien Collateral Agent, be segregated from the other property or funds of such Grantor and be forthwith delivered to the First Lien Collateral Agent as Security Collateral in the same form as so received (with any necessary indorsement), (B) dividends and other distributions paid or payable in cash in respect of any Security Collateral in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid in surplus shall be deposited in the Revenue Account or such other account as provided for in the Security Deposit Agreement, and (C) cash paid, payable or otherwise distributed in respect of principal of, or in redemption of, or in exchange for, any Security Collateral shall be deposited in the Revenue Account or such other account as provided for in the Security Deposit Agreement. (iii) The First Lien Collateral Agent will execute and deliver (or cause to be executed and delivered) to each Grantor all such proxies and other instruments as such Grantor may reasonably request for the purpose of enabling such Grantor to exercise the voting and other rights that it is entitled to exercise

If any Grantor fails to perform any agreement contained herein, the First Lien Collateral Agent may, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the First Lien Collateral Agent incurred in connection therewith shall be payable by such Grantor under Section 7.10 of the Intercreditor Agreement. Section 17. The First Lien Collateral Agent’s Duties.
