The Borrower represents and warrants to the Lenders and the Agents that: (a) the execution of this Agreement and the fulfillment of the terms hereof will not result in a breach of any of the terms or provisions of, or constitute a default under, the Borrower's Articles of Incorporation or By-Laws as presently in effect, or any order, rule or regulation applicable to the Borrower of any court or of any Federal or state regulatory body or administrative agency or other governmental body having jurisdiction over the Borrower, or result in the termination or cancellation or breach of any indenture, mortgage, deed of trust, deed to secure debt, lease or other agreement or instrument to which the Borrower is party or by which it is bound or affected; (b) the Borrower has taken all necessary corporate action to authorize the execution and delivery of this Agreement, and this Agreement, when executed and delivered, will be the valid and binding obligation of the Borrower enforceable in accordance with its terms, subject only to the following qualifications: (i) certain equitable remedies are discretionary and, in particular, may not be available where damages are considered an adequate remedy at law, (ii) enforcement may be limited by bankruptcy, insolvency, liquidation, reorganization, reconstruction and other similar laws affecting enforcement of creditors' rights generally (insofar as any such law relates to the bankruptcy, insolvency or similar event of the Borrower), and (iii) enforcement as to the Licenses is limited by FCC rules and regulations restricting the transfer of such Licenses. (c) Exhibit A attached hereto and incorporated herein by this reference sets forth a complete and accurate list of the Contracts in effect on the date hereof which provide for aggregate payments over the life of each such Contract in excess of $250,000 or which are otherwise material to the Borrower, and the Borrower will furnish copies thereof to the Lenders and the Agents upon the request of the Collateral Agent; and (d) Exhibit B attached hereto and incorporated herein by this reference sets forth a complete and accurate list of all Leases providing for aggregate payments over the life of any single Lease in excess of $100,000, to which the Borrower is party in effect on the date hereof, and the Borrower will furnish copies thereof to the Lenders and the Agents upon the request of the Collateral Agent. 4. The Borrower further represents and warrants that the Security Interest in the Collateral granted hereunder shall constitute at all times a valid and perfected first priority security interest (subject only to Permitted Liens), vested in the Collateral Agent in and upon the Collateral, free of any Liens except for Permitted Liens. The Borrower shall take or cause to be taken such acts and actions as shall be necessary or appropriate to assure that the Security Interest in the Collateral shall not become subordinate or junior to the security interests, liens or claims of any other Person, and that the Collateral shall not otherwise be or become subject to any Lien, except for Permitted Liens. 5. The Borrower further represents and warrants that it now keeps all of its records concerning its Accounts, Contracts, Leases, Other Contracts and Intangibles at its chief executive office, which is the address set forth with respect to the Borrower in Section 11.1 of the Loan Agreement. The Borrower covenants and agrees that it shall not keep any of such records at any other address, unless written notice thereof is given to the Collateral Agent at least thirty (30) days prior to the creation of any new address for the keeping of such records. The Borrower further agrees that it shall promptly advise the Collateral Agent, in writing making reference to this Section 5 of this Agreement, of the opening of any material new place of business the closing of any existing material place of business, or any change in the location of the place where it keeps the Collateral. 6. The parties intend that, to the extent permitted by Applicable Law, the Collateral shall remain personal property irrespective of the manner of its attachment or affixation to realty. 7. Any and all injury to, or loss or destruction of, the Collateral shall be at the Borrower's risk, and shall not release the Borrower from its obligations hereunder. The Borrower agrees not to sell, transfer, assign, dispose of, mortgage, grant a security interest in or encumber any of the Collateral except as permitted under the Loan Agreement. The Borrower agrees to maintain in force such insurance with respect to the Collateral as is required under the Loan Agreement. The Borrower agrees to pay all required taxes, liens and assessments upon the Collateral, its use or operation, as required under the Loan Agreement. The Borrower further agrees that the Collateral Agent may, but shall in no event be obligated to, insure any of the Collateral in such form and amount as the Collateral Agent may deem necessary or desirable if the Borrower fails to obtain insurance as required by the Loan Agreement, and that the Collateral Agent may pay or discharge any taxes or Liens (which are not Permitted Liens) on any of the Collateral, and the Borrower agrees to pay any such sum so expended by the Collateral Agent, with interest at the Default Rate, and such interest shall be deemed to be a part of the Obligations secured by the Collateral under the terms of this Agreement. 8. The Borrower shall (i) fulfill, perform and observe each and every material condition and covenant contained in any of the Contracts, the Other Contracts or the Leases, (ii) give prompt notice to the Collateral Agent of any claim of default under any Contract, Other Contract or Lease given to the Borrower or by the Borrower, (iii) at the sole cost and expense of the Borrower, enforce the performance and observance of each and every material covenant and condition of the Contracts, the Other Contracts and the Leases and (iv) appear in and defend any action growing out of or in any manner connected with any Contract, Other Contract or Lease. The rights and interests granted to the Collateral Agent hereunder include all of the Borrower's rights and title (i) to modify the Contracts, the Other Contracts and the Leases, (ii) to terminate the Contracts, the Other Contracts and the Leases and (iii) to waive or release the performance or observance of any obligation or condition of the Contracts, the Other Contracts and the Leases; provided, however, that the Borrower shall have the right to exercise these rights in a fashion consistent with this Agreement and the Loan Agreement prior to any Default (as defined below), and that these rights shall not be exercised by the Collateral Agent prior to a Default (as defined below). 9. Upon the occurrence and during the continuation of an Event of Default (hereinafter, a "Default"), the Lenders and the Agents shall have such rights and remedies as are set forth in the Loan Agreement and herein; all the rights, powers and privileges of a secured party under the Uniform Commercial Code of the State of New York and any other applicable jurisdiction; and all other rights and remedies available to the Lenders and the Agents, or any of them, at law or in equity, including, without limitation, the right to sell or dispose of the Collateral in accordance with Applicable Law. The Borrower covenants and agrees that any notification of intended disposition of any Collateral, if such notice is required by law, shall be deemed reasonably and properly given if given in the manner provided for in paragraph 19 hereof at least ten (10) days prior to such disposition. The Collateral Agent shall have the right to the appointment of a receiver for the properties and assets of the Borrower, and the Borrower hereby consents to such rights and to such appointment and hereby waives any objection the Borrower may have thereto and hereby waives the right to have a bond or other security posted by the Collateral Agent or any other Person in connection therewith. The Borrower agrees, after the occurrence of a Default, to take any actions that the Collateral Agent may reasonably request in order to enable the Collateral Agent to obtain and enjoy the full rights and benefits granted to the Collateral Agent under this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, the Borrower shall, at the Borrower's cost and expense, use its best efforts to assist in obtaining all approvals of the FCC or the State of New York Public Service Commission, as applicable, which are then required by law for or in connection with any action or transaction contemplated by this Agreement or Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction, and, at the Collateral Agent's request, prepare, sign and file with the FCC or the State of New York Public Service Commission, as applicable, the assignor's or transferor's portion of any application or applications for consent to the assignment of the Licenses or transfer of control thereof necessary or appropriate under the FCC's or the State of New York Public Service Commission's, as applicable, rules for approval of any sale or transfer of the Collateral Agent's remedies under this Agreement. The Collateral Agent shall have the right, in connection with the issuance of any order for relief in a bankruptcy proceeding to petition the bankruptcy court for the transfer of control or assignment of the Licenses to a receiver, trustee, transferee, or similar official or to any purchaser of the Collateral pursuant to any public or private sale, foreclosure or other exercise of remedies available to the Collateral Agent, all as permitted by Applicable Law. All amounts realized or collected through the exercise of remedies hereunder shall be applied as provided in the Loan Agreement. 10. Upon the occurrence of a Default, the Collateral Agent or its designee, may proceed to perform any and all of the obligations of the Borrower contained in any of the Contracts, Other Contracts or Leases and exercise any and all rights of the Borrower therein contained as fully as the Borrower itself could. The Borrower hereby appoints the Collateral Agent its attorney-in-fact, with power of substitution, to take such action, execute such documents, and perform such work, as the Collateral Agent may deem appropriate in exercise of the rights and remedies granted the Lenders and the Agents, or any of them, herein or in any other Loan Document. The powers herein granted shall include, but not be limited to, powers to: (i) sue on the Contracts, the Other Contracts or the Leases; (ii) seek all governmental approvals (other than FCC approvals) required for the operation of the business of the Borrower; (iii) modify or terminate the Contracts, the Other Contracts and the Leases; and (iv) waive or release the performance or observance of any obligation under any of the Contracts, Other Contracts or Leases. The power of attorney granted herein is coupled with an interest and shall be irrevocable. 11. Upon the occurrence of a Default, should the Borrower fail to perform or observe any covenant or comply with any condition contained in any of the Contracts, the Other Contracts or the Leases, then the Collateral Agent may, but without obligation to do so and without releasing the Borrower from its obligation to do so, perform such covenant or condition and, to the extent that the Collateral Agent shall incur any costs or pay any expenses in connection therewith, including any reasonable costs or expenses of litigation associated therewith, such costs, expenses or payments shall be included in the Obligations secured hereby and shall bear interest from the payment of such costs or expenses by the Collateral Agent at the Default Rate. None of the Lenders or the Agents shall be obliged to perform or discharge any obligation of the Borrower under any of the Contracts, the Other Contracts or the Leases, and, except as may result from the gross negligence or willful misconduct of the Person seeking indemnification as determined by a final order of a court of competent jurisdiction, the Borrower agrees to indemnify and hold harmless each Lender and each Agent against any and all liability, loss or damage which any such Person may incur under any of the Contracts, the Other Contracts or the Leases or under or by reason of this Agreement, and any and all claims and demands whatsoever which may be asserted against the Borrower by reason of an act of any Lender or any Agent under any of the terms of this Agreement or under the Contracts, the Other Contracts or the Leases. 12. The Borrower hereby further appoints the Collateral Agent as its attorney-in-fact, with power of substitution, with authority to collect all Accounts, to endorse the name of the Borrower on any note, acceptance, check, draft, money order or other evidence of debt or of payment which constitutes a portion of the Collateral and which may come into the possession of the Lenders and the Agents, or any of them, and generally to do such other things and acts in the name of the Borrower with respect to the Collateral as are necessary or appropriate to protect or enforce the rights hereunder of the Lenders and the Agents. The Borrower further authorizes the Collateral Agent, effective upon the occurrence of a Default, to compromise and settle or to sell, assign or transfer or to ask, collect, receive or issue any and all claims possessed by the Borrower which constitute a portion of the Collateral, all in the name of the Borrower. After deducting all reasonable expenses and charges (including the Collateral Agent's attorneys' fees) of retaking, keeping, storing and selling the Collateral, the Collateral Agent may apply the proceeds in payment of any of the Obligations in the order of application set forth in the Loan Agreement. The power of attorney granted herein is coupled with an interest and shall be irrevocable. The Borrower agrees that if steps are taken by the Collateral Agent to enforce its rights hereunder, or to realize upon any of the Collateral, the Borrower shall pay to the Collateral Agent the amount of the Collateral Agent's costs, including attorneys' fees, and the Borrower's obligation to pay such amounts shall be deemed to be a part of the Obligations secured hereunder. 13. The Borrower shall indemnify and hold harmless each Lender and each Agent and any other Person acting hereunder for all losses, costs, damages, fees and expenses whatsoever associated with the exercise of the powers of attorney granted herein and shall release each Lender and each Agent and any other Person acting hereunder from all liability whatsoever for the exercise of the foregoing powers of attorney and all actions taken pursuant thereto, except, in either event, in the case of gross negligence or willful misconduct by the Person seeking indemnification as determined by a final order of a court of competent jurisdiction. 14. The Borrower agrees that the rights of the Lenders and the Agents, or any of them, under this Agreement, the Loan Agreement, any other Loan Document, or any other contract or agreement now or hereafter in existence among the Lenders and the Agents and the Borrower or any Subsidiary of the Borrower and any other obligors thereunder, or any of them, shall be cumulative, and that each Lender and each Agent may from time to time exercise such rights and such remedies as such Person or Persons may have thereunder and under the laws of the United States or any state, as applicable, in the manner and at the time that such Person or Persons in its or their sole discretion desire, subject to the terms of such agreements. The Borrower further expressly agrees that the Lenders and the Agents shall in no event be under any obligation to resort to any Collateral prior to exercising any other rights that the Lenders and the Agents, or any of them, may have against the Borrower or any Subsidiary of the Borrower or any other obligor or any of their respective properties, nor shall the Lenders and the Agents be obliged to resort to any other collateral or security for the Obligations, other than the Collateral, prior to any exercise of rights against the Borrower and its property hereunder. 15. The Borrower hereby acknowledges that the Obligations arose out of a commercial transaction, and agrees that if a Default shall occur, the Collateral Agent shall have the right to immediate possession without notice or a hearing, and hereby knowingly and intelligently waives any and all rights it may have to any notice and posting of a bond by the Lenders and the Agents, or any of them, prior to seizure by the Collateral Agent or any of its transferees, assigns or successors in interest, of the Collateral or any portion thereof. 16. No transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by the Borrower or any other obligor to the Lenders and the Agents, or any of them, nor additional advances made by the Lenders and the Agents, or any of them, to the Borrower, nor the taking of further security, nor the retaking or re-delivery of the Collateral to the Borrower by the Lenders and the Agents, or any of them, nor any other act of the Lenders and the Agents, or any of them, shall release the Borrower from any Obligation, except a release or discharge executed in writing by the Collateral Agent in accordance with the Loan Agreement with respect to such Obligation or upon full payment, performance and satisfaction of all Obligations and termination of the Commitments. None of the Lenders or the Agents shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Collateral Agent in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Lenders and the Agents, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion. 17. Neither this Agreement nor any of the Borrower's rights or obligations hereunder may be assigned by the Borrower to any other Person. The Borrower agrees that this Agreement or the rights hereunder may in the discretion of the Lenders and the Agents, as applicable, be assigned in whole or in part in connection with any assignment of the Loan Agreement or the Indebtedness evidenced thereby, as permitted thereunder. In the event this Agreement or the rights hereunder are so assigned by any of the Lenders, the Co-Agents, the Agents, the Managing Agents, the Administrative Agent, the Documentation Agent and the Collateral Agent, the terms "Lenders", "Co-Agents", "Agents", "Managing Agents", "Administrative Agent", "Documentation Agent" or "Collateral Agent" wherever used herein shall be deemed, as applicable, to refer to and include any such assignee. 18. The Collateral Agent is hereby authorized to date this Agreement as of the date signed by the Borrower. This Agreement shall apply to and bind the respective successors and assigns of the Borrower and inure to the benefit of the successors and permitted assigns of the Lenders and the Agents. 19. All notices and other communications required or permitted hereunder shall be in writing and shall be given in the manner prescribed in Section 11.1 of the Loan Agreement. 20.

THIS AGREEMENT, TOGETHER WITH ALL DOCUMENTS REFERRED TO HEREIN, CONSTITUTES THE ENTIRE AGREEMENT AMONG THE BORROWER, THE LENDERS AND THE AGENTS WITH RESPECT TO THE MATTERS ADDRESSED HEREIN, AND MAY NOT BE MODIFIED EXCEPT BY A WRITING EXECUTED BY THE COLLATERAL AGENT AND THE BORROWER AND DELIVERED BY THE COLLATERAL AGENT TO THE BORROWER IN ACCORDANCE WITH THE LOAN AGREEMENT. 21. If any paragraph or part thereof of this Agreement shall for any reason be held or adjudged to be invalid, illegal or unenforceable by any court of competent jurisdiction, such paragraph or part thereof so adjudicated invalid, illegal or unenforceable shall be deemed separate, distinct and independent, and the remainder of this Agreement shall remain in full force and effect and shall not be affected by such holding or adjudication. 22. Notwithstanding anything herein which may be construed to the contrary, no action shall be taken by the Collateral Agent with respect to the Licenses issued by the FCC or any governmental or other authority unless and until all requirements of Applicable Law requiring notice to, or consent or approval of such action by, the FCC or any governmental or other authority, have been satisfied, including, without limitation, any required approval of the FCC under the Federal Communications Act of 1934 as amended, and any applicable rules and regulations thereunder, including, without limitation, the provision for ten (10) days' notice to the FCC and to the Borrower of any such action to the extent required by 47 C.F.R. (Section Mark) 22.917(e). The Borrower covenants that upon request of the Collateral Agent it will cause to be filed such applications and take such other action as may be requested by the Collateral Agent to obtain consent or approval of the FCC or any governmental or other authority which has granted any License to the Borrower to any action contemplated by this Agreement and to give effect to the Security Interest of the Collateral Agent, including, without limitation, the execution of an application for consent by the FCC to an assignment or transfer involving a change in ownership or control pursuant to the provisions of the Federal Communications Act of 1934 as amended. 23. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument. 24. The parties acknowledge their intent that, upon the occurrence of a Default, the Collateral Agent shall receive, to the fullest extent permitted by Applicable Law and governmental policy (including, without limitation, the rules, regulations and policies of the FCC), all rights necessary or desirable to obtain, use or sell the Collateral, and to exercise all remedies available to it under this Agreement, the Uniform Commercial Code as in effect in any applicable jurisdiction, or other Applicable Law. The parties further acknowledge and agree that, in the event of changes in law or governmental policy occurring subsequent to the date hereof, that affect in any manner the Collateral Agent's rights of access to, or use or sale of, the Collateral, or the procedures necessary to enable the Collateral Agent to obtain such rights of access, use or sale, the Collateral Agent and the Borrower shall amend this Agreement in such manner as the Collateral Agent shall reasonably request, in order to provide the Collateral Agent such rights to the greatest extent possible consistent with Applicable Law and governmental policy. 25. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the "Collateral Agent" shall be a reference to the Collateral Agent for the benefit of all the Lenders and the Agents, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Collateral Agent for the benefit of and on behalf of all the Lenders and the Agents.
