Agreement, of), a continuing security interest in all of the right, title and interest, powers, remedies, privileges and other benefits of such Assignor in, to and under all of the following personal property and fixtures (and all rights therein) of such Assignor, or in which or to which such Assignor has any rights, in each case whether now existing or hereafter from time to time acquired:

(xxii) all Supporting Obligations; and

(xxiii) all Proceeds and products of any and all of the foregoing (all of the above, the “Collateral”);

provided that (x) no Assignor shall be required to grant a security interest hereunder in (and the term “Collateral” shall not include) (i) any Excluded Account (so long as same remains an “Excluded Account” in accordance with the definition thereof), (ii) any contract, license, agreement, instrument, document, permit or franchise that validly prohibits, restricts or requires the consent not obtained of a third party for the creation by such Assignor of a security interest in such contract, license, agreement, instrument, document, permit or franchise (or in any rights or property obtained by such Assignor under such contract, license, agreement, instrument, document, permit or franchise) except to the extent provided by Sections 9-406, 9-407, 9-408 and 9-409 of the UCC, and (iii) any rights or property to the extent that any valid and enforceable law or statute or rule, regulation, guideline, order or directive of a governmental authority or agency applicable to such rights or property prohibits, restricts, or requires the consent of a third party for, or would result in the termination of such rights or property as a result of, the creation of a security interest therein except to the extent provided by Sections 9-406, 9-407, 9-408 and 9-409 of the UCC (solely to the extent the UCC is controlling), (y) subject to the immediately succeeding proviso, no Assignor shall be required to grant a security interest hereunder in (and the term “Collateral” shall not include) any licenses and permits issued by the FCC, any PUC or any other Governmental Authority to the extent, and only to the extent, it is unlawful to grant a security interest in such licenses and permits (and upon such grant of a security being lawful, whether because of a change of law, the obtaining of any necessary consents or otherwise, the security interests granted hereunder automatically (and without any further action) shall extend to such licenses and/or permits); provided that the foregoing limitation shall not exclude the grant of a security interest pursuant to this Section 1.1(a) in all proceeds derived from or in connection with the sale, assignment or transfer of such licenses and permits, and (z) (i) except in the circumstances and to the extent provided by Section 9.16 of the Credit

Page 4

Agreement, no Assignor shall be required to grant a security interest hereunder in (and the term “Collateral” shall not include) the Voting Equity Interests of any Exempted Foreign Entity constituting more than 65% of the total combined voting power of all Voting Equity Interests of such Exempted Foreign Entity and (ii) subject to compliance with Section 10.12(b) of the Credit Agreement, no Assignor shall be required to grant a security interest hereunder in (and the term “Collateral” shall not include) any Equity Interests in US LEC PAC. For the avoidance of doubt, notwithstanding the preceding sentence, each Assignor shall be required to grant a security interest hereunder in 100% of the Non-Voting Equity Interests of each Exempted Foreign Entity at any time and from time to time acquired by such Assignor.

(b) The security interest of the Collateral Agent under this Agreement extends to all Collateral which any Assignor may acquire, or with respect to which any Assignor may obtain rights, at any time during the term of this Agreement.

(c) Notwithstanding anything to the contrary contained in this Section 1.1, the term “Collateral”, as it only refers to the Collateral securing the Additional First Lien Obligations, shall not include any Equity Interests and other securities of a Subsidiary of the Borrower to the extent that the pledge of such Equity Interests and other securities would result in the Borrower or such Subsidiary being required to file separate financial statements of such Subsidiary with the SEC, but only to the extent necessary to not be subject to such requirement and only for so long as such requirement is in existence and only with respect to the relevant Additional First Lien Obligations affected thereby; provided that neither the Borrower nor any of its Subsidiaries shall take any action in the form of a reorganization, merger or other restructuring a principal purpose of which is to provide for the release of the Lien on any Equity Interest or other securities pursuant to this clause (c). In addition, in the event that Rule 3-16 of Regulation S-X under the Securities Act (“Rule 3-16”) is amended, modified or interpreted by the SEC to require (or is replaced by another rule or regulation, or any other law, rule or regulation is adopted, which would require) the filing with the SEC (or any other Governmental Authority) of separate financial statements of any Subsidiary of the Borrower due to the fact that such Subsidiary’s Equity Interests or other securities secure the Additional First Lien Obligations affected thereby, then the Equity Interests or other securities of such Subsidiary will automatically be deemed not to be part of the Collateral securing the relevant Additional First Lien Obligations affected thereby but only to the extent necessary to not be subject to such requirement and only for so long as required to not be subject to such requirement. In such event, this Agreement may be amended or modified, without the consent of any Secured Creditor, to the extent necessary to release the security interests in favor of the Collateral Agent on the Equity Interests or other securities that are so deemed to no longer constitute part of the Collateral for the relevant Additional First Lien Obligations only. In the event that Rule 3-16 is amended, modified or interpreted by the SEC to permit (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would permit) such Subsidiary’s Equity Interests or other securities to secure the Additional First Lien Obligations in excess of the amount then pledged without the filing with the SEC (or any other Governmental Authority) of separate financial statements of such Subsidiary, then the Equity Interests or other securities of such Subsidiary will automatically be deemed to be a part of the Collateral for the relevant Additional First Lien Obligations. For the avoidance of doubt and notwithstanding anything to the contrary contained in this Agreement, nothing in this clause (c) shall limit the

Page 5

pledge of such Equity Interests and other securities from securing the Credit Document Obligations and the Other Obligations at all times or from securing any Additional First Lien Obligations that are not in respect of securities subject to regulation by the SEC. For purposes of this clause (c), “securities” has the meaning ascribed to such term for purposes of Rule 3-16.

(d) This Agreement amends and restates the Original Security Agreement. The Obligations of the Assignors under the Original Security Agreement and the grant of security interest in the Collateral by the Assignors under the Original Security Agreement shall continue (uninterrupted) under this Agreement, and shall not in any event be terminated, extinguished or annulled, but shall hereafter be governed by this Agreement. All references to the Original Security Agreement in any Credit Document (other than this Agreement) or other document or instrument delivered in connection therewith shall be deemed to refer to this Agreement and the provisions hereof. It is understood and agreed that the Original Security Agreement is being amended and restated by entry into this Agreement on the date hereof.

1.2 Power of Attorney. Each Assignor hereby constitutes and appoints the Collateral Agent its true and lawful attorney, irrevocably, with full power after the occurrence of and during the continuance of an Event of Default (in the name of such Assignor or otherwise) to act, require, demand, receive, compound and give acquittance for any and all moneys and claims for moneys due or to become due to such Assignor under or arising out of the Collateral, to endorse any checks or other instruments or orders in connection therewith and to file any claims or take any action or institute any proceedings which the Collateral Agent may deem to be necessary or advisable to protect the interests of the Secured Creditors, which appointment as attorney is coupled with an interest.

ARTICLE II

GENERAL REPRESENTATIONS, WARRANTIES AND COVENANTS

Each Assignor represents, warrants and covenants, which representations, warranties and covenants shall survive execution and delivery of this Agreement, as follows:

2.1 Necessary Filings. All filings, registrations, recordings and other actions necessary or appropriate to create, preserve and perfect the security interest granted by such Assignor to the Collateral Agent hereby in respect of the Collateral have been accomplished (other than any such actions necessary or appropriate to perfect such security interest in the Deposit Accounts) and the security interest granted to the Collateral Agent pursuant to this Agreement in and to the Collateral creates a valid and, together with all such filings, registrations, recordings and other actions (and except with respect to the Deposit Accounts), a perfected security interest therein prior to the rights of all other Persons therein and subject to no other Liens (other than Permitted Liens) and, except with respect to the security interest in the Deposit Accounts, is entitled to all the rights, priorities and benefits afforded by the Uniform Commercial Code or other relevant law as enacted in any relevant jurisdiction to perfected security interests, in each case to the extent that the Collateral consists of the type of property in which a security interest may be perfected by possession or control (within the meaning of the UCC as in effect on the date hereof in the State of New York), by filing a financing statement under the Uniform Commercial Code as enacted in any relevant jurisdiction or by a filing of a Grant of Security Interest in the respective form attached hereto in the United States Patent and Trademark Office or in the United States Copyright Office.

2.3 Other Financing Statements. As of the date hereof, there is no financing statement (or similar statement or instrument of registration under the law of any relevant jurisdiction) covering or purporting to cover any interest of any kind in the Collateral (other than financing statements filed in respect of Permitted Liens), and so long as the Termination Date has not occurred, such Assignor will not execute or authorize to be filed in any public office any financing statement (or similar statement or instrument of registration under the law of any jurisdiction) or statements relating to the Collateral, except financing statements filed or to be filed in respect of and covering the security interests granted hereby by such Assignor or in connection with Permitted Liens.

Page 7

as the case may be, outside the United States or a State thereof) if (i) it shall have given to the Collateral Agent not less than 15 days’ prior written notice of each change to the information listed on Annex C (as adjusted for any subsequent changes thereto previously made in accordance with this sentence), together with a supplement to Annex C which shall correct all information contained therein for such Assignor, and (ii) in connection with such change or changes, it shall have taken all action reasonably requested by the Collateral Agent to maintain the security interest of the Collateral Agent in the Collateral intended to be granted hereby at all times fully perfected and in full force and effect. In addition, to the extent that such Assignor does not have an organizational identification number on the date hereof and later obtains one, such Assignor shall promptly thereafter notify the Collateral Agent of such organizational identification number and shall take all actions reasonably requested by the Collateral Agent to maintain the security interest of the Collateral Agent in the Collateral intended to be granted hereby fully perfected and in full force and effect.

2.7 Trade Names; Etc. No Assignor has or operates in any jurisdiction under, or in the preceding five years has had or has operated in any jurisdiction under, any trade names, fictitious names or other names except its legal name as specified in Annex C and such other trade or fictitious names as are listed on Annex D hereto for such Assignor. Such Assignor shall not assume or operate in any jurisdiction under any new trade, fictitious or other name until (i) it shall have given to the Collateral Agent not less than 15 days’ written notice of its intention so to do, clearly describing such new name and the jurisdictions in which such new name will be used and providing such other information in connection therewith as the Collateral Agent may reasonably request and (ii) with respect to such new name, it shall have taken all action reasonably requested by the Collateral Agent to maintain the security interest of the Collateral Agent in the Collateral intended to be granted hereby at all times fully perfected and in full force and effect.

2.8 Certain Significant Transactions. During the one year period preceding the date of this Agreement, no Person shall have merged or consolidated with or into such Assignor, and no Person shall have liquidated into, or transferred all or substantially all of its assets to, such Assignor, in each case except as described in Annex E hereto. With respect to any transactions so described in Annex E hereto, such Assignor shall have furnished to the Collateral Agent such information as reasonably requested by the Collateral Agent with respect to the Person (and the assets of the Person and locations thereof) which merged with or into or consolidated with such Assignor, or was liquidated into or transferred all or substantially all of its assets to such Assignor, and shall have furnished to the Collateral Agent such UCC lien searches as reasonably requested by the Collateral Agent with respect to such Person and its assets, to establish that no security interest (excluding Permitted Liens) continues perfected on the date hereof with respect to any Person described above (or the assets transferred to the respective Assignor by such Person), including without limitation pursuant to Section 9-316(a)(3) of the UCC.

2.9 Non-UCC Property. The aggregate fair market value (as determined by the Assignors in good faith) of all property of the Assignors of the types described in clauses (1), (2) and (3) of Section 9-311(a) of the UCC does not exceed $1,000,000. If the aggregate value of all such property at any time owned by all Assignors exceeds $1,000,000, the Assignors shall provide prompt written notice thereof to the Collateral Agent and, upon the request of the

Page 8

Collateral Agent, the Assignors shall promptly (and in any event within 30 days) take such actions (at their own cost and expense) as may be required under the respective United States, State or other laws referenced in Section 9-311(a) of the UCC to perfect the security interests granted herein in any Collateral where the filing of a financing statement does not perfect the security interest in such property in accordance with the provisions of Section 9-311(a) of the UCC.

2.10 As-Extracted Collateral; Timber-to-be-Cut. On the date hereof, such Assignor does not own, or expect to acquire, any property which constitutes, or would constitute, As-Extracted Collateral or Timber-to-be-Cut.

If any Inventory or other Goods are at any time in the possession of a bailee, such Assignor shall promptly notify the Collateral Agent thereof and, if requested by the Collateral Agent, shall use its reasonable best efforts to promptly obtain an acknowledgment from such bailee, in form and substance reasonably satisfactory to the Collateral Agent, that the bailee holds such Collateral for the benefit of the Collateral Agent and shall act upon the instructions of the Collateral Agent without the further consent of such Assignor. The Collateral Agent agrees with such Assignor that the Collateral Agent shall not give any such instructions unless an Event of Default has occurred and is continuing.

2.12 Recourse. This Agreement is made with full recourse to each Assignor and pursuant to and upon all the warranties, representations, covenants and agreements on the part of such Assignor contained herein, in the Secured Debt Agreements and otherwise in writing in connection herewith or therewith.

INSTRUMENTS; CHATTEL PAPER AND CERTAIN OTHER COLLATERAL

3.1 Additional Representations and Warranties. As of the time when each of its Accounts arises, each Assignor shall be deemed to have represented and warranted that each such Account, and all records, papers and documents relating thereto (if any) are genuine and what they purport to be, and that all papers and documents (if any) relating thereto (a) will, to the knowledge of such Assignor, represent the genuine, legal, valid and binding obligation of the account debtor evidencing indebtedness unpaid and owed by the respective account debtor arising out of the performance of labor or services or the sale or lease and delivery of the merchandise listed therein, or both, (b) will be the only original writings evidencing and embodying such obligation of the account debtor named therein (other than copies created for general accounting purposes), and (c) to the knowledge of such Assignor, will be in compliance and will conform in all material respects with all applicable federal, state and local laws and applicable laws of any relevant foreign jurisdiction.

Each Assignor will keep and maintain at its own cost and expense accurate records of its Accounts and Contracts, including, but not limited to, originals or copies of all documentation (including each Contract) with respect thereto, records of all payments received, all credits granted thereon, all merchandise returned and all other dealings therewith, and such Assignor will make the same available on such Assignor’s premises to the Collateral Agent for inspection during normal business hours, at such Assignor’s own cost and expense, at any and all reasonable times upon reasonable prior notice to such Assignor and otherwise in accordance with the Credit Agreement and any equivalent provision of any Additional First Lien Document. Upon the occurrence and during the continuance of an Event of Default and at the request of the Collateral Agent, such Assignor shall, at its own cost and expense, deliver all tangible evidence of its Accounts and Contract Rights (including, without limitation, all documents evidencing the Accounts and all Contracts) and such books and records to the Collateral Agent or to its representatives (copies of which evidence and books and records may be retained by such Assignor). Upon the occurrence and during the continuance of an Event of Default and if the Collateral Agent so directs, such Assignor shall legend, in form and manner satisfactory to the Collateral Agent, the Accounts and the Contracts, as well as books, records and documents (if any) of such Assignor evidencing or pertaining to such Accounts and Contracts, with an appropriate reference to the fact that such Accounts and Contracts have been assigned to the Collateral Agent and that the Collateral Agent has a security interest therein.

3.3 Direction to Account Debtors; Contracting Parties; etc. Upon the occurrence and during the continuance of an Event of Default, if the Collateral Agent so directs any Assignor, such Assignor agrees (a) to cause all payments on account of the Accounts and Contracts to be made directly to the Cash Collateral Account, (b) that the Collateral Agent may, at its option, directly notify the obligors with respect to any Accounts and/or under any Contracts to make payments with respect thereto as provided in the preceding clause (a), and (c) that the Collateral Agent may enforce collection of any such Accounts and Contracts and may adjust, settle or compromise the amount of payment thereof, in the same manner and to the same extent as such Assignor. Without notice to or assent by any Assignor, the Collateral Agent may, upon the occurrence and during the continuance of an Event of Default, apply any or all amounts then in, or thereafter deposited in, the Cash Collateral Account toward the payment of the Obligations in the manner provided in Section 7.4 of this Agreement. The reasonable costs and expenses of collection (including reasonable attorneys’ fees), whether incurred by an Assignor or the Collateral Agent, shall be borne by the relevant Assignor. The Collateral Agent shall deliver a copy of each notice referred to in the preceding clause (b) to the relevant Assignor, provided that (x) the failure by the Collateral Agent to so notify such Assignor shall not affect the effectiveness of such notice or the other rights of the Collateral Agent created by this Section 3.3 and (y) no such notice shall be required if an Event of Default of the type described in Section 11.05 of the Credit Agreement (or any equivalent provision of any Additional First Lien Document) has occurred and is continuing.

3.4 Modification of Terms; etc. Except in accordance with such Assignor’s ordinary course of business and consistent with reasonable business judgment or as

Page 10

permitted by Section 3.5(a) hereof, no Assignor shall rescind or cancel any material indebtedness evidenced by any Account or under any Contract, or modify any material term thereof or make any material adjustment with respect thereto, or extend or renew the same, or compromise or settle any material dispute, claim, suit or legal proceeding relating thereto, or sell any Account or Contract, or interest therein, without the prior written consent of the Collateral Agent. No Assignor will do anything to impair the rights of the Collateral Agent in the Accounts or Contracts.

3.5 Collection. (a) Each Assignor shall endeavor in accordance with reasonable business practices to cause to be collected from the account debtor named in each of its Accounts or obligor under any Contract, as and when due any and all amounts owing under or on account of such Account or Contract (including, without limitation, amounts which are delinquent, such amounts to be collected in accordance with generally accepted lawful collection procedures) and apply forthwith upon receipt thereof all such amounts as are so collected to the outstanding balance of such Account or under such Contract. Except as otherwise directed by the Collateral Agent after the occurrence and during the continuation of an Event of Default, any Assignor may allow in the ordinary course of business as adjustments to amounts owing under its Accounts and Contracts (i) an extension or renewal of the time or times of payment, or settlement for less than the total unpaid balance, which such Assignor finds appropriate in accordance with reasonable business judgment and (ii) a refund or credit due as a result of returned or damaged merchandise or improperly performed services or for other reasons which such Assignor finds appropriate in accordance with reasonable business judgment. The reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees) of collection, whether incurred by an Assignor or the Collateral Agent, shall be borne by the relevant Assignor. Each Assignor may assign Accounts to collection agencies in accordance with such Assignor’s current practices in effect on the date hereof, to the extent permitted by the Credit Agreement and each Additional First Lien Document.

(b) In accordance with its reasonable business judgment, at each applicable Assignor’s sole cost and expense, such Assignor will appear in and defend any action or proceedings arising under, growing out of or in any manner connected with the obligations, covenants, conditions, duties, agreements or obligations of Assignor under any Contract and/or Account of such Assignor.

3.6 Instruments. If any Assignor owns or acquires any Instrument constituting Collateral (other than (a) checks and other payment instruments received and collected in the ordinary course of business and (b) any Instrument subject to pledge pursuant to the Pledge Agreement), such Assignor will within 10 Business Days notify the Collateral Agent thereof, and upon request by the Collateral Agent will promptly deliver such Instrument to the Collateral Agent appropriately endorsed to the order of the Collateral Agent.

3.7 Assignors Remain Liable Under Accounts. (a) Anything herein to the contrary notwithstanding, the Assignors shall remain liable under each of the Accounts to observe and perform all of the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise to such Accounts. Neither the Collateral Agent nor any other Secured Creditor shall have any obligation or liability under any Account (or any agreement giving rise thereto) by reason of or arising out of this

Page 11

Agreement or the receipt by the Collateral Agent or any other Secured Creditor of any payment relating to such Account pursuant hereto, nor shall the Collateral Agent or any other Secured Creditor be obligated in any manner to perform any of the obligations of any Assignor under or pursuant to any Account (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by them or as to the sufficiency of any performance by any party under any Account (or any agreement giving rise thereto), to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to them or to which they may be entitled at any time or times.

(b) Should any Assignor fail to perform or discharge its obligations or duties under the Accounts as required in Section 3.7(a) above, then the Collateral Agent may, but shall have no obligation to (and shall not thereby release Assignor from any obligation hereunder), perform or discharge any such obligation or duty to such extent as the Collateral Agent may, in its reasonable business judgment, deem necessary or advisable to protect the security provided hereby, including appearing in and defending any action or proceeding purporting to affect the security hereof and the rights or powers of the Collateral Agent hereunder. In exercising any such powers, the Collateral Agent may pay necessary and reasonable costs (including reasonable attorneys’ and paralegals’ fees and expenses), and all such reasonable expenses paid or incurred by the Collateral Agent shall be for the account of the respective Assignor and shall constitute additional Obligations of such Assignor, payable upon demand, and shall bear interest at the default rate of interest set forth in the Credit Agreement.

3.8 Assignors Remain Liable Under Contracts. (a) Anything herein to the contrary notwithstanding, the Assignors shall remain liable under each of the Contracts to observe and perform all of the conditions and obligations to be observed and performed by them thereunder, all in accordance with and pursuant to the terms and provisions of each Contract. Neither the Collateral Agent nor any other Secured Creditor shall have any obligation or liability under any Contract by reason of or arising out of this Agreement or the receipt by the Collateral Agent or any other Secured Creditor of any payment relating to such Contract pursuant hereto, nor shall the Collateral Agent or any other Secured Creditor be obligated in any manner to perform any of the obligations of any Assignor under or pursuant to any Contract, to make any payment, to make any inquiry as to the nature or the sufficiency of any performance by any party under any Contract, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to them or to which they may be entitled at any time or times.

(b) Should any Assignor fail to perform or discharge its obligations or duties under the Contracts as required in Section 3.8(a) above, then the Collateral Agent may, but shall have no obligation to (and shall not thereby release Assignor from any obligation hereunder), perform or discharge any such obligation or duty to such extent as the Collateral Agent may, in its reasonable business judgment, deem necessary or advisable to protect the security provided hereby, including appearing in and defending any action or proceeding purporting to affect the security hereof and the rights or powers of the Collateral Agent hereunder. In exercising any such powers, the Collateral Agent may pay necessary and reasonable costs (including reasonable attorneys’ and paralegals’ fees and expenses), and all such reasonable expenses paid or incurred by the Collateral Agent shall be for the account of the respective Assignor and shall constitute additional Obligations of such Assignor, payable upon demand, and shall bear interest at the default rate of interest set forth in the Credit Agreement.

3.9 Deposit Accounts; Etc. (a) No Assignor shall establish or maintain at any time any demand, time, savings, passbook or similar account, except for such accounts maintained with a bank (as defined in Section 9-102 of the UCC) whose jurisdiction (determined in accordance with Section 9-304 of the UCC) is within a State of the United States.Annex F hereto accurately sets forth, as of the date of this Agreement, for each Assignor, each Deposit Account maintained by such Assignor (including a description thereof and the respective account number) and the name of the respective bank with which such Deposit Account is maintained. For each Deposit Account (other than (i) the Cash Collateral Account, (ii) any other Deposit Account maintained with the Collateral Agent, (iii) any Excluded Account and (iv) any Minor Account), the respective Assignor shall cause the bank with which the Deposit Account is maintained to execute and deliver to the Collateral Agent, to the extent such Deposit Account is not the subject of a “control agreement” as described below on the date of this Agreement, within 60 days after the date of this Agreement (as such date may be extended by the Collateral Agent in its sole discretion) or, if later, at the time of the establishment of the respective Deposit Account, a “control agreement” in the form of Annex G hereto (appropriately completed), with such changes thereto as may be reasonably acceptable to the Collateral Agent, or if after using commercially reasonable efforts to enter into such control agreement, the respective bank refuses to enter into such control agreement, another control agreement in form and substance reasonably satisfactory to the Collateral Agent and its counsel. Subject to Section 3.9(b), if any bank with which a Subject Deposit Account is maintained refuses to, or does not, enter into such a “control agreement”, then the respective Assignor shall promptly (and in any event within 60 days after the date of this Agreement (as such date may be extended by the Collateral Agent in its sole discretion) or, if later, at the time of the establishment of such account) close the respective Subject Deposit Account and transfer all balances therein to the Cash Collateral Account or another Subject Deposit Account meeting the requirements of this Section 3.9. If any bank with which a Subject Deposit Account is maintained refuses to subordinate all its claims with respect to such Subject Deposit Account (other than claims for its reasonable and customary fees for administering such account) to the Collateral Agent’s security interest therein on terms satisfactory to the Collateral Agent, then the Collateral Agent, at its option, may (x) require that such Subject Deposit Account be terminated in accordance with the immediately preceding sentence or (y) agree to a “control agreement” without such subordination, provided that in such event the Collateral Agent may at any time, at its option, subsequently require that such Subject Deposit Account be terminated (within 30 days after notice from the Collateral Agent) in accordance with the requirements of the immediately preceding sentence.

(b) Notwithstanding anything to the contrary contained in this Agreement, if any bank with which a Subject Deposit Account listed on Annex F (other than (i) the Cash Collateral Account, (ii) any other Deposit Account maintained with the Collateral Agent and (iii) any Minor Account) hereto is maintained refuses to, or does not, enter into a “control agreement” with respect to such Subject Deposit Account within 60 days after the date hereof as otherwise required pursuant to Section 3.9(a) hereof, then the applicable Assignor shall not be required to close such Subject Deposit Account until 45 days have elapsed from the expiration of such initial 60-day period, so long as (i) such Assignor continues working in good faith to close such Subject Deposit Account within such extended 45-day period and (ii) the average monthly balance of all

Page 13

Subject Deposit Accounts that are neither subject to a “control agreement” nor closed, in each case within such initial 60-day period, does not exceed $2,500,000 during such extended 45-day period.

(c) At the time any new Deposit Account is established, the respective Assignor shall furnish to the Collateral Agent a supplement to Annex F hereto containing the relevant information with respect to the respective Deposit Account and the bank with which same is established.

If any Assignor is at any time a beneficiary under a letter of credit with a stated amount of $500,000 or more, such Assignor shall promptly notify the Collateral Agent thereof and, at the request of the Collateral Agent, such Assignor shall, pursuant to an agreement in form and substance reasonably satisfactory to the Collateral Agent, use its reasonable best efforts to (i) arrange for the issuer and any confirmer of such letter of credit to consent to an assignment to the Collateral Agent of the proceeds of any drawing under such letter of credit or (ii) arrange for the Collateral Agent to become the transferee beneficiary of such letter of credit, with the Collateral Agent agreeing, in each case, that the proceeds of any drawing under the letter of credit are to be delivered to the Assignor, except after the occurrence and during the continuance of an Event of Default, in which case such proceeds shall be applied as provided in this Agreement.

3.11 Commercial Tort Claims. All Commercial Tort Claims of each Assignor in existence on the date of this Agreement are described in Annex H hereto. If any Assignor shall at any time after the date of this Agreement acquire a Commercial Tort Claim in an amount (taking the greater of the aggregate claimed damages thereunder or the reasonably estimated value thereof) of $500,000 or more, such Assignor shall promptly notify the Collateral Agent thereof in a writing signed by such Assignor and describing the details thereof and shall grant to the Collateral Agent in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to the Collateral Agent.

3.12 Chattel Paper. Upon the request of the Collateral Agent made at any time or from time to time, each Assignor shall promptly furnish to the Collateral Agent a list of all Electronic Chattel Paper held or owned by such Assignor. Furthermore, if requested by the Collateral Agent, each Assignor shall promptly take all actions which are reasonably practicable so that the Collateral Agent has “control” of all Electronic Chattel Paper in accordance with the requirements of Section 9-105 of the UCC. Each Assignor will promptly (and in any event within 10 days) following any request by the Collateral Agent, deliver all of its Tangible Chattel Paper to the Collateral Agent.

3.13 Further Actions. Each Assignor will, at its own expense and upon the request of the Collateral Agent make, execute, endorse, acknowledge, file and/or deliver to the Collateral Agent from time to time such schedules, confirmatory assignments, conveyances, financing statements, transfer endorsements, certificates, reports and other assurances or instruments and take such further steps, including any and all actions as may be necessary or required under the Federal Assignment of Claims Act, relating to its Accounts, Contracts, Instruments and other property or rights covered by the security interest hereby granted, which the Collateral Agent deems reasonably necessary to perfect, preserve or protect its security interest in the collateral.

Each Assignor assumes all liability and responsibility in connection with the Collateral acquired by it and the liability of such Assignor to pay the Obligations shall in no way be affected or diminished by reason of the fact that such Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever unavailable to such Assignor.

Page 18

To the extent practicable, each Assignor agrees that if any warehouse receipt or receipt in the nature of a warehouse receipt is issued with respect to any of its Inventory, such Assignor shall request that such warehouse receipt or receipt in the nature thereof shall not be “negotiable” (as such term is used in Section 7-104 of the Uniform Commercial Code as in effect in any relevant jurisdiction or under other relevant law).

6.3 Additional Information. Each Assignor will, at its own expense, from time to time upon the reasonable request of the Collateral Agent or any Authorized Representative, promptly (and in any event within 10 days after its receipt of the respective request) furnish to the Collateral Agent or such Authorized Representative such information with respect to the Collateral (including the identity of the Collateral or such components thereof as may have been requested by the Collateral Agent or such Authorized Representative, the value and location of such Collateral, etc.) as may be requested by the Collateral Agent or such Authorized Representative.

(i) personally, or by agents or attorneys, immediately take possession of the Collateral or any part thereof from such Assignor or any other Person who then has possession of any part thereof with or without notice or process of law, and for that purpose may enter upon such Assignor’s premises where any of the Collateral is located and remove the same and use in connection with such removal any and all services, supplies, aids and other facilities of such Assignor;

(ii) instruct the obligor or obligors on any agreement, instrument or other obligation (including, without limitation, the Accounts and the Contracts) constituting the Collateral to make any payment required by the terms of such agreement, instrument or other obligation directly to the Collateral Agent and may exercise any and all remedies of such Assignor in respect of such Collateral;

it being understood that each Assignor’s obligation so to deliver the Collateral is of the essence of this Agreement and that, accordingly, upon application to a court of equity having jurisdiction, the Collateral Agent shall be entitled to a decree requiring specific performance by such Assignor of said obligation. By accepting the benefits of this Agreement and each other Security Document, the Secured Creditors expressly acknowledge and agree that this Agreement and each other Security Document may be enforced only by the action of the Collateral Agent acting upon the instructions of (i) at any time that the First Lien Intercreditor Agreement is not in effect, the Required Credit Agreement Secured Creditors or (ii) at any time that the First Lien Intercreditor Agreement is in effect, the Applicable Authorized Representative as provided in the First Lien Intercreditor Agreement (provided that if the Applicable Authorized Representative is the Administrative Agent, the Administrative Agent shall act upon the instructions of the Required Credit Agreement Secured Creditors), and that no other Secured Creditor otherwise 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 Collateral Agent for the benefit of the Secured Creditors upon the terms of this Agreement, the other Security Documents and the First Lien Intercreditor Agreement.

(b) Without limiting the generality of the foregoing, in connection with the exercise of its remedies under this Agreement or under any of the other Secured Debt Agreements, the Collateral Agent may obtain the appointment of a receiver or trustee to assume, upon receipt of all necessary judicial, FCC, any PUC or other Governmental Authority consents or approvals, control of or ownership of any of the Governmental Approvals to the extent permitted by, or in accordance with, applicable law. Such receiver or trustee shall have all rights and powers provided to it by law or by court order or provided to the Collateral Agent under this Agreement or any other Secured Debt Agreement. Upon the appointment of such trustee or receiver, each Assignor agrees to cooperate, to the extent necessary or reasonably desired by the Collateral Agent, in the expeditious preparation, execution and filing of an application to the FCC, any PUC or any other Governmental Authority for consent to the transfer of control or assignment of any Assignor’s Governmental Approvals to such receiver or trustee.

Page 21

(c) In connection with the enforcement by the Collateral Agent of any remedies available to it as a result of any Event of Default, each Assignor agrees that it shall join and cooperate fully with, at the request of the Collateral Agent, any receiver referred to below and/or the successful bidder or bidders at any foreclosure sale in a filing of an application (and furnishing any additional information that may be required in connection with such application or which the Collateral Agent may believe relevant to such application) with the FCC, any PUC and all other applicable Governmental Authorities, requesting their prior approval of (i) the operation or abandonment of all or the portion of any System and/or (ii) the transfer of control of such Assignor or assignment of all licenses, certificates, Governmental Approvals, approvals and permits, issued to such Assignor by the FCC, any PUC or any such Governmental Authorities with respect to any System and the operation thereof, to the Collateral Agent, the receiver or to the successful bidder or bidders. In connection with the foregoing, each Assignor shall take such further actions, and execute all such instruments, as the Collateral Agent reasonably deems necessary or desirable. Each Assignor agrees that the Collateral Agent may enforce any obligation of such Assignor as set forth in this Section by an action for specific performance. The exercise of any rights or remedies hereunder or under any other Credit Document by the Collateral Agent or any other Secured Creditor that may require FCC, any PUC or any other Governmental Authority approval shall be subject to obtaining such approval. Pending the receipt of any FCC, any PUC or any other Governmental Authority approval, each Assignor shall fully cooperate with, and not do anything to delay, hinder, interfere or obstruct, such Secured Creditor’s exercise of its rights in obtaining such approvals.

(d) Each Assignor expressly authorizes the Collateral Agent, and the Collateral Agent may, but shall not be required to, at any time and from time to time, to take any and all action that it reasonably determines to be necessary or desirable to cure any default or violation (including a payment default) of such Assignor in connection with any lease, license agreement, Governmental Approval or any other material lease, agreement or contract entered into with respect to the Systems. Any and all amounts expended by the Collateral Agent in connection with such actions shall be for the account of such Assignor and shall constitute Obligations secured hereunder.

7.2 Remedies; Disposition of the Collateral. If any Event of Default shall have occurred and be continuing, then any Collateral repossessed by the Collateral Agent under or pursuant to Section 7.1(a) hereof and any other Collateral whether or not so repossessed by the Collateral Agent, may be sold, assigned, leased or otherwise disposed of under one or more contracts or as an entirety, and without the necessity of gathering at the place of sale the property to be sold, and in general in such manner, at such time or times, at such place or places and on such terms as the Collateral Agent may, in compliance with any mandatory requirements of applicable law, determine to be commercially reasonable. Any of the Collateral may be sold, leased or otherwise disposed of, in the condition in which the same existed when taken by the Collateral Agent or after any overhaul or repair, at the expense of the relevant Assignor, which the Collateral Agent shall determine to be commercially reasonable. Any such sale, lease or other disposition may be effected by means of a public disposition or private disposition, effected in accordance with the applicable requirements (in each case if and to the extent applicable) of Sections 9-610 through 9-613 of the UCC and/or such other mandatory requirements of applicable law as may apply to the respective disposition. The Collateral Agent may, without notice or publication, adjourn any public or private disposition or cause the same to

Page 22

be adjourned from time to time by announcement at the time and place fixed for the disposition, and such disposition may be made at any time or place to which the disposition may be so adjourned. To the extent permitted by any such requirement of law, the Collateral Agent may bid for and become the purchaser (and may pay all or any portion of the purchase price by crediting Obligations against the purchase price) of the Collateral or any item thereof, offered for disposition in accordance with this Section 7.2 without accountability to the relevant Assignor, provided that the Collateral Agent shall then notify the relevant Assignor of such purchase and the purchase price. If, under applicable law, the Collateral Agent shall be permitted to make disposition of the Collateral within a period of time which does not permit the giving of notice to the relevant Assignor as hereinabove specified, the Collateral Agent need give such Assignor only such notice of disposition as shall be required by such applicable law. Each Assignor agrees to do or cause to be done all such other acts and things as may be reasonably necessary to make such disposition or dispositions of all or any portion of the Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over any such sale or sales, all at such Assignor’s expense.

7.3 Waiver of Claims. Except as otherwise provided in this Agreement, EACH ASSIGNOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE COLLATERAL AGENT’S TAKING POSSESSION OR THE COLLATERAL AGENT’S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES, and each Assignor hereby further waives, to the extent permitted by law:

(i) all damages occasioned by such taking of possession or any such disposition except any damages which are the direct result of the Collateral Agent’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision);

(ii) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Collateral Agent’s rights hereunder; and

(iii) all rights of redemption, appraisement, valuation, stay, extension or moratorium now or hereafter in force under any applicable law in order to prevent or delay the enforcement of this Agreement or the absolute sale of the Collateral or any portion thereof, and each Assignor, for itself and all who may claim under it, insofar as it or they now or hereafter lawfully may, hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon, any Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the relevant Assignor therein and thereto, and shall be a perpetual bar both at law and in equity against such Assignor and against any and all Persons claiming or attempting to claim the Collateral so sold, optioned or realized upon, or any part thereof, from, through and under such Assignor.

7.4 Application of Proceeds. (a) All moneys collected by the Collateral Agent (or, to the extent the Pledge Agreement or any other Security Document requires proceeds of collateral under such other Security Document to be applied in accordance with the provisions of this Agreement, the Pledgee or collateral agent under such other Security Document) upon any sale or other disposition of the Collateral, together with all other moneys received by the Collateral Agent hereunder, shall be applied (A) at any time that the First Lien Intercreditor Agreement is in effect, in accordance with the terms thereof (and with the amount to be applied to (x) the Credit Document Obligations and the Other Obligations, to be applied in the manner provided in succeeding clause (B) and (y) the Additional First Lien Obligations, to be applied in accordance with the relevant Additional First Lien Documents) or (B) at any time that that the First Lien Intercreditor Agreement is not in effect or as provided in preceding sub-clause (A)(x), to the Credit Document Obligations and Other Obligations as follows:

(i) first, to the payment of all amounts owing to the Collateral Agent of the type described in clauses (v), (vi) and (vii) of the definition of “Obligations”;

(ii) second, to the extent proceeds remain after the application pursuant to the preceding clause (i), an amount equal to the outstanding Primary Obligations shall be paid to the Credit Agreement Secured Creditors as provided in Section 7.4(e) hereof, with each Credit Agreement Secured Creditor receiving an amount equal to its outstanding Primary Obligations or, if the proceeds are insufficient to pay in full all such Primary Obligations, its Pro Rata Share of the amount remaining to be distributed;

(iii) third, to the extent proceeds remain after the application pursuant to the preceding clauses (i) and (ii), an amount equal to the outstanding Secondary Obligations shall be paid to the Credit Agreement Secured Creditors as provided in Section 7.4(e) hereof, with each Credit Agreement Secured Creditor receiving an amount equal to its outstanding Secondary Obligations or, if the proceeds are insufficient to pay in full all such Secondary Obligations, its Pro Rata Share of the amount remaining to be distributed; and

(iv) fourth, to the extent proceeds remain after the application pursuant to the preceding clauses (i) through (iii), inclusive, and following the termination of this Agreement pursuant to Section 10.8(a) hereof, to the relevant Assignor or to whomever may be lawfully entitled to receive such surplus.

(b) For purposes of this Agreement, (x) “Pro Rata Share” shall mean, when calculating a Credit Agreement Secured Creditor’s portion of any distribution or amount, that amount (expressed as a percentage) equal to a fraction the numerator of which is the then unpaid amount of such Credit Agreement Secured Creditor’s Primary Obligations or Secondary Obligations, as the case may be, and the denominator of which is the then outstanding amount of all Primary Obligations or Secondary Obligations, as the case may be, (y) “Primary Obligations” shall mean (i) in the case of the Credit Document Obligations, all principal of, premium, and interest on, all Loans, all Unpaid Drawings, the Stated Amount of all outstanding Letters of Credit and all Fees and (ii) in the case of the Other Obligations, all amounts due under each Secured Hedging Agreement (other than indemnities, fees (including, without limitation, attorneys’ fees) and similar obligations and liabilities) and (z) “Secondary Obligations” shall mean all Obligations constituting Credit Document Obligations and Other Obligations other than Primary Obligations.

Page 24

(c) When payments to Credit Agreement Secured Creditors are based upon their respective Pro Rata Shares, the amounts received by such Credit Agreement Secured Creditors hereunder shall be applied (for purposes of making determinations under this Section 7.4 only) (i) first, to their Primary Obligations and (ii) second, to their Secondary Obligations. If any payment to any Credit Agreement Secured Creditor of its Pro Rata Share of any distribution would result in overpayment to such Credit Agreement Secured Creditor, such excess amount shall instead be distributed in respect of the unpaid Primary Obligations or Secondary Obligations, as the case may be, of the other Credit Agreement Secured Creditors, with each Credit Agreement Secured Creditor whose Primary Obligations or Secondary Obligations, as the case may be, have not been paid in full to receive an amount equal to such excess amount multiplied by a fraction the numerator of which is the unpaid Primary Obligations or Secondary Obligations, as the case may be, of such Credit Agreement Secured Creditor and the denominator of which is the unpaid Primary Obligations or Secondary Obligations, as the case may be, of all Credit Agreement Secured Creditors entitled to such distribution.

(d) Each of the Credit Agreement Secured Creditors, by their acceptance of the benefits hereof and of the other Security Documents, agrees and acknowledges that if the Lender Creditors receive a distribution on account of undrawn amounts with respect to Letters of Credit issued under the Credit Agreement (which shall only occur after all outstanding Revolving Loans and Swingline Loans under the Credit Agreement and Unpaid Drawings have been paid in full), such amounts shall be paid to the Administrative Agent under the Credit Agreement and held by it, for the equal and ratable benefit of the Lender Creditors, as cash security for the repayment of Obligations owing to the Lender Creditors as such. If any amounts are held as cash security pursuant to the immediately preceding sentence, then upon the termination of all outstanding Letters of Credit under the Credit Agreement, and after the application of all such cash security to the repayment of all Obligations owing to the Lender Creditors after giving effect to the termination of all such Letters of Credit, if there remains any excess cash, such excess cash shall be returned by the Administrative Agent to the Collateral Agent for distribution in accordance with Section 7.4(a) hereof.

(e) All payments required to be made hereunder in respect of the Credit Document Obligations and the Other Obligations shall be made (x) if to the Lender Creditors, to the Administrative Agent for the account of the Lender Creditors and (y) if to the Other Creditors, to the trustee, paying agent or other similar representative (each, a “Representative”) for the Other Creditors or, in the absence of such a Representative, directly to the Other Creditors.

(f) For purposes of applying payments to the Credit Document Obligations and the Other Obligations received in accordance with this Section 7.4, the Collateral Agent shall be entitled to rely upon (i) the Administrative Agent and (ii) the Representative or, in the absence of such a Representative, upon the Other Creditors for a determination (which the Administrative Agent, each Representative and the Other Creditors agree (or shall agree) to provide upon request of the Collateral Agent) of the outstanding Primary Obligations and Secondary Obligations owed to the Lender Creditors or the Other Creditors, as the case may be. Unless it

Page 25

has received written notice from a Lender Creditor or an Other Creditor to the contrary, the Administrative Agent and each Representative, in furnishing information pursuant to the preceding sentence, and the Collateral Agent, in acting hereunder, shall be entitled to assume that no Secondary Obligations are outstanding. Unless it has written notice from an Other Creditor to the contrary, the Collateral Agent, in acting hereunder, shall be entitled to assume that no Secured Hedging Agreements are in existence.

(g) It is understood that the Assignors shall remain jointly and severally liable to the extent of any deficiency between the amount of the proceeds of the Collateral and the aggregate amount of the Obligations.

7.5 Remedies Cumulative. Each and every right, power and remedy hereby specifically given to the Collateral Agent shall be in addition to every other right, power and remedy specifically given to the Collateral Agent under this Agreement, the other Secured Debt Agreements or now or hereafter existing at law, in equity or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed reasonable by the Collateral Agent. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right to exercise any other or others. No delay or omission of the Collateral Agent in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Default or Event of Default or an acquiescence thereof. No notice to or demand on any Assignor in any case shall entitle it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the Collateral Agent to any other or further action in any circumstances without notice or demand. In the event that the Collateral Agent shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Collateral Agent may recover reasonable expenses, including reasonable attorneys’ fees, and the amounts thereof shall be included in such judgment.

7.6 Discontinuance of Proceedings. In case the Collateral Agent shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case the relevant Assignor, the Collateral Agent and each holder of any of the Obligations shall be restored to their former positions and rights hereunder with respect to the Collateral subject to the security interest created under this Agreement, and all rights, remedies and powers of the Collateral Agent shall continue as if no such proceeding had been instituted.
