If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Rate. SECTION 2.10. Funding Losses. If the Borrower makes any payment of principal with respect to any Euro-Dollar Loan or any Euro-Dollar Loan is converted (pursuant to Article 2, 6 or 8 or otherwise) on any day other than the last day of an Interest Period applicable thereto, or the last day of an applicable period fixed pursuant to Section 2.05(c), or if the Borrower fails to borrow or prepay any Euro-Dollar Loans after notice has been given to any Bank in accordance with Section 2.02(a), 2.04 or 2.08, the Borrower shall reimburse each Bank within 15 days after demand for any resulting loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin for the period after any such payment or conversion or failure to borrow or prepay, provided that such Bank shall have delivered to the Borrower a certificate as to the amount of such loss or expense, which certificate shall be conclusive in the absence of manifest error. SECTION 2.11. Computation of Interest and Fees. Interest based on the Prime Rate and commitment fees hereunder shall be computed on the basis of a 28 year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first day but excluding the last day). All other interest shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day). SECTION 2.12. Extension of Maturity Date. If the Borrower wishes to extend the Maturity Date then in effect, the Borrower shall give written notice to the Administrative Agent not less than 13 months nor more than 18 months prior to the Maturity Date then in effect, whereupon the Administrative Agent shall promptly notify each Bank of such notice. Each Bank will use its reasonable efforts to respond to such request in writing, whether affirmatively or negatively, as it may elect in its sole discretion, within 30 days after it receives such notice from the Administrative Agent. If the Administrative Agent receives an affirmative response in writing from each Bank within such 30 day period, the Maturity Date then in effect shall be extended for one year (but in no event later than March 31, 2006) and the Administrative Agent shall notify the Borrower (with a copy to the Shareholder Guarantors, it being understood that the consent of the Shareholder Guarantors is not required for any such extension and any failure to give any such notice shall not affect any Shareholder Guarantor's obligations under its Shareholder Guaranty) and the Banks of such extension.

SECTION 4.03. Government Approvals. All material Government Approvals heretofore required to be obtained have been duly obtained, were validly issued, are in full force and effect, are not subject to appeal and are held in the name of, or for the benefit of, the appropriate Persons. There is no proceeding pending or, to the best knowledge of the Borrower, threatened against the Borrower or any of its Subsidiaries, or any property of the Borrower or any of its Subsidiaries, which seeks, or may reasonably be expected, to rescind, terminate, materially adversely modify or suspend any of the FCC Licenses. There has not occurred any event that would make unlikely the delivery or issuance as anticipated of, and when and as needed all such Government Approvals. No such Government Approval already obtained is subject to any restriction, condition, limitation or other provision that would have a Material Adverse Effect. The information set forth in each application submitted by the Borrower or any of its Subsidiaries in connection with each such Government Approval is accurate and complete in all material respects taken as a whole, except for statements or omissions which could not reasonably be expected to affect adversely the validity of such Government Approvals.

All written descriptions thereof provided to the Agents are true and complete in all material respects. Each Plan is in compliance in all material respects with the applicable provisions of ERISA, the Code and other Federal or state law, including all requirements under the Code or ERISA for filing reports (which are true and correct in all material respects as of the date filed), and benefits have been paid in accordance with the provisions of the Plan. Each Qualified Plan has been determined by the IRS to qualify under Section 401 of the Code, and to the best knowledge of the Borrower nothing has occurred which would cause the loss of such qualification. 34 (b) There is no outstanding liability under Title IV of ERISA with respect to any Plan maintained or sponsored by any member of the Controlled Group (as to which the Borrower is or may be liable), nor with respect to any Plan to which any member of the Controlled Group contributes or is obligated to contribute (wherein the Borrower is or may be liable). No Plan maintained or sponsored by the Borrower provides medical or other welfare benefits or extends coverage relating to such benefits beyond the date of a participant's termination of employment with the Borrower, except to the extent required by Section 4980B of the Code and at the sole expense of the participant or the beneficiary of the participant to the fullest extent permissible under such Section of the Code. The Borrower has complied in all material respects with the notice and continuation coverage requirements of Section 4980B of the Code. (c) No ERISA Event has occurred or is reasonably expected to occur with respect to any Plan maintained or sponsored by the Borrower or to which the Borrower is obligated to contribute.

The Borrower has not transferred any Unfunded Pension Liability outside of the Controlled Group or otherwise engaged in a transaction that could be subject to Section 4069 or 4212(c) of ERISA.

SECTION 4.08. Title to Property. Each of the Borrower and its Subsidiaries has good record and marketable title in fee simple to or valid leasehold interests in all real property used in its business, except for such defects in title as could not, individually or in the aggregate, have a Material Adverse Effect. Such real property is free and clear of all Liens or rights of others, except Permitted Liens. 35 SECTION 4.09. Taxes. Each of the Borrower and its Subsidiaries has filed all Federal and other material tax returns and reports required to be filed and have paid all Federal and other material taxes, assessments, fees and other governmental charges levied or imposed upon them or their properties, income or assets otherwise due and payable except those which are being contested in good faith by appropriate proceedings and for which adequate reserves have been provided in accordance with GAAP and no Notice of Lien has been filed or recorded.

(b) The unaudited pro forma summary consolidated condensed balance sheet of the Borrower and its Subsidiaries as of September 30, 1997 together with the related pro forma summary condensed statement of operations data for the nine months then ended fairly present, in conformity with GAAP applied on a basis consistent with the financial statements referred to in subsection (a) above, the consolidated financial position of the Borrower and its Subsidiaries as of such date, based on the assumptions set forth therein. As of such date and the Closing Date, the Borrower and its Subsidiaries had and have no material liabilities, contingent or otherwise, which are not properly reflected on such balance sheet (including liabilities for taxes and material commitments). (c) Since September 30, 1997, there has been no Material Adverse Effect. SECTION 4.11. Environmental Matters. The operations of the Borrower and each of its Subsidiaries comply in all material respects with all Environmental Laws. The Borrower and each of its Subsidiaries have obtained all licenses, permits, authorizations and registrations required under any Environmental Law ("Environmental Permits") necessary for its operations to comply in all material 36 respects with Environmental Laws, and all such Environmental Permits are in full force and effect, and the Borrower and each of its Subsidiaries are in material compliance with all terms and conditions of such Environmental Permits. None of the Borrower, any of its Subsidiaries or any of their present or, to the knowledge of the Borrower, past property or operations is subject to any outstanding written order from or agreement with any Governmental Authority or other Person, nor subject to any judicial or administrative proceeding, respecting any Environmental Law, Environmental Claim or Hazardous Material. There are no conditions or circumstances which may give rise to any Environmental Claim arising from the operations of the Borrower or its Subsidiaries, including Environmental Claims associated with any operations of the Borrower or its Subsidiaries, with a potential liability in excess of $5,000,000 in the aggregate. Without limiting the generality of the foregoing, the Borrower and its Subsidiaries have met all notification requirements under Title III of the Superfund Amendments and Reauthorization Act of 1986 or any other Environmental Law.

Neither the business nor the properties of the Borrower and its Subsidiaries are or have been affected by any fire, explosion, accident, strike, lockout or other labor dispute, drought, storm, hail, earthquake, embargo, act of God or of the public enemy or other casualty (whether or not covered by insurance) which has had a Material Adverse Effect. SECTION 4.16. Collateral; Property. All contracts and all property now owned by the Borrower are held by it free and clear of all Liens other than 37 Permitted Liens. The Borrower has good, marketable and valid title in and to all of the Collateral now owned by it, in each case free and clear of all Liens other than Permitted Liens. SECTION 4.17. Security and Pledge Agreement. The Security and Pledge Agreement creates in favor of the Administrative Agent, for the equal and ratable (except as expressly provided therein) benefit of the Secured Parties, legal, valid and enforceable Liens on or in all of the Collateral to the extent that such Liens may legally be given and be effective and enforceable. All filings, recordations, registrations and other actions necessary to perfect such Liens have been duly effected, and, to the extent that such Liens may legally be given and be effective and enforceable, each Lien created by the Security and Pledge Agreement constitutes a perfected Lien on or in all right, title, estate and interest of the Borrower in the Collateral covered thereby, prior and superior to all other Liens except Permitted Liens arising by operation of law, and all necessary and appropriate consents to the creation and perfection of such Liens have been obtained. SECTION 4.18. Disclosure. The information (including, without limitation, the information in the Offering Memorandum) furnished in writing at or prior to the Closing Date by the Borrower to any Agent or Bank in connection with this Agreement and the transactions contemplated hereby is true, complete and accurate in every material respect or based on reasonable estimates on the date as of which such information is stated or certified and is not incomplete by omitting to state any material fact necessary to make such information (taken as a whole) not misleading in light of the circumstances under which such information was made.

Upon the acceptance of its appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation hereunder as Agent, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent. SECTION 7.09. Agents' Fees. The Borrower shall pay to each Agent for its own account fees in the amounts and at the times previously agreed upon between the Borrower and such Agent. 57 ARTICLE 8 CHANGE IN CIRCUMSTANCES SECTION 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Euro-Dollar Loan: (a) the Administrative Agent is advised by the Reference Banks that deposits in dollars (in the applicable amounts) are not being offered to the Reference Banks in the London interbank market for such Interest Period, or (b) Banks having 50% or more of the aggregate principal amount of the affected Loans advise the Administrative Agent that the Adjusted London Interbank Offered Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks of funding their Euro-Dollar Loans for such Interest Period, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, (i) the obligations of the Banks to make Euro-Dollar Loans or to continue or convert outstanding Loans as or into Euro-Dollar Loans shall be suspended and (ii) each outstanding Euro-Dollar Loan shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto. Unless the Borrower notifies the Administrative Agent at least two Domestic Business Days before the date of the Borrowing, if it is to be a Euro-Dollar Borrowing, for which the Notice of Borrowing has previously been given that it elects not to borrow on such date, the Borrowing shall instead be made as a Base Rate Borrowing. The Administrative Agent shall notify the Borrower as soon as reasonably possible upon learning that the circumstances giving rise to such suspension no longer exist. SECTION 8.02. Illegality. If, on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Bank shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrower, 58 whereupon until such Bank notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Bank to make Euro-Dollar Loans, or to convert outstanding Loans into Euro-Dollar Loans, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Bank shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If such notice is given, each Euro-Dollar Loan of such Bank then outstanding shall be converted to a Base Rate Loan either (a) on the last day of the then current Interest Period applicable to such Euro-Dollar Loan if such Bank may lawfully continue to maintain and fund such Loan to such day or (b) immediately if such Bank shall determine that it may not lawfully continue to maintain and fund such Loan to such day. Each Bank shall notify the Administrative Agent and the Borrower as soon as reasonably possible after the circumstances giving rise to any suspension by such Bank described in this Section 8.02 no longer exist. SECTION 8.03. Increased Cost and Reduced Return. (a) If on or after the date hereof, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding any such requirement included in an applicable Euro-Dollar Reserve Percentage), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Applicable Lending Office) or shall impose on any Bank (or its Applicable Lending Office) or the London interbank market any other condition affecting its Euro-Dollar Loans, its Note or its obligation to make Euro-Dollar Loans and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any Euro-Dollar Loan, or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note with respect thereto, by an amount deemed by such Bank to be material, then, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction; provided, however, that in the case of an increase referred to above resulting from the published interpretation by a governmental authority, such Bank shall be entitled to make demand on the Borrower in respect thereof only within 180 days of the publication of such interpretation. 59 (b) If any Bank shall have determined that, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank's obligations hereunder to a level below that which such Bank (or its Parent) could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank (or its Parent) for such reduction; provided, however, that in the case of an increase referred to above resulting from the published interpretation by a governmental authority, such Bank shall be entitled to make demand on the Borrower in respect thereof only within 180 days of the publication of such interpretation. (c) Each Bank will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. Each Bank will notify the Administrative Agent and the Borrower as soon as reasonably possible after any circumstance entitling such Bank to compensation pursuant to this Section 8.03(c) no longer exists. SECTION 8.04. Taxes. (a) For the purposes of this Section 8.04 , the following terms have the following meanings: "Taxes" means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by the Borrower, as the case may be, pursuant to this Agreement or under any Note, and all liabilities with respect thereto, excluding (i) in the case of each Bank and Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by a jurisdiction under the laws of which such Bank or Agent (as the case 60 may be) is organized or in which its principal executive office is located or, in the case of each Bank, in which its Applicable Lending Office is located and (ii) in the case of each Bank, any United States withholding tax imposed on such payments but only to the extent that such Bank is subject to United States withholding tax at the time such Bank first becomes a party to this Agreement. "Other Taxes" means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or levies, which arise from any payment made pursuant to this Agreement or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note. (b) Any and all payments by the Borrower to or for the account of any Bank or Agent hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be required by law to deduct any Taxes or Other Taxes from any such payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) such Bank or Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 9.01 , the original or a certified copy of a receipt evidencing payment thereof. (c) The Borrower agrees to indemnify each Bank and Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section) paid by such Bank or Agent (as the case may be) and any liability (including penalties, interest and expenses, other than those resulting from any act or failure to act by such Bank) arising therefrom or with respect thereto. This indemnification shall be paid within 15 days after such Bank or Agent (as the case may be) makes demand therefor. (d) Each Bank organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Bank listed on the signature pages hereof and on or prior to the date on which it becomes a Bank in the case of each other Bank, and from time to time thereafter if requested in writing by the Borrower (but only so long as such Bank remains lawfully able to do so), shall provide the Borrower and the Administrative Agent with Internal Revenue Service form 1001 or 4224, as appropriate, or any successor form prescribed by the Internal Revenue Service, certifying that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which exempts the Bank from United 61 States withholding tax or reduces the rate of withholding tax on payments of interest for the account of such Bank or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States. (e) For any period with respect to which a Bank has failed to provide the Borrower or the Administrative Agent with the appropriate form pursuant to Section 8.04(d) (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which such form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 8.04(b) or 8.04(c) with respect to Taxes imposed by the United States; provided that if a Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Taxes. (f) If the Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section, then such Bank will change the jurisdiction of its Applicable Lending Office if, in the judgment of such Bank, such change (i) will eliminate or reduce any such additional payment which may thereafter accrue and (ii) is not otherwise disadvantageous to such Bank. SECTION 8.05. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Bank to make, or convert outstanding Loans to, Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03 or 8.04 with respect to its Euro-Dollar Loans and the Borrower shall, by at least five Euro-Dollar Business Days' prior notice to such Bank through the Administrative Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer exist: (a) all Loans which would otherwise be made by such Bank as (or continued as or converted into) Euro-Dollar Loans shall instead be Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks); and (b) after each of its Euro-Dollar Loans has been repaid (or converted to a Base Rate Loan), all payments of principal which would otherwise be applied to repay such Euro-Dollar Loans shall be applied to repay its Base Rate Loans instead. 62 If such Bank notifies the Borrower that the circumstances giving rise to such notice no longer apply, the principal amount of each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Banks. ARTICLE 9 MISCELLANEOUS SECTION 9.01. Notices. All notices, requests and other communications to any party hereunder shall be in writing (including bank wire, facsimile transmission or similar writing) and shall be given to such party: (a) in the case of the Borrower or either Agent, at its address or facsimile number set forth on the signature pages hereof, (b) in the case of any Bank, at its address or facsimile number set forth in its Administrative Questionnaire or (c) in the case of any party, such other address or facsimile number as such party may hereafter specify for the purpose by notice to the Agents and the Borrower. Each such notice, request or other communication shall be effective (i) if given by facsimile transmission, when transmitted to the facsimile number specified in this Section and confirmation of receipt is received, (ii) if given by mail, 72 hours after such communication is deposited in the mails with first class postage prepaid, addressed as aforesaid or (iii) if given by any other means, when delivered at the address specified in this Section; provided that notices to the Administrative Agent under Article 2 or Article 8 shall not be effective until received. SECTION 9.02. No Waivers. No failure or delay by either Agent or any Bank in exercising any right, power or privilege hereunder or under any Note shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. SECTION 9.03. Expenses; Indemnification. (a) The Borrower shall pay (i) all out-of-pocket expenses of the Agents, including reasonable fees and disbursements of special counsel for the Agents, in connection with the preparation and administration of this Agreement, any waiver or consent hereunder or any amendment hereof or any Default or alleged Default hereunder and (ii) if an Event of Default occurs, all out-of-pocket expenses incurred by each Agent and Bank, including (without duplication) the fees and disbursements of outside counsel and the allocated cost of inside counsel, in connection with such Event of Default and collection, bankruptcy, insolvency and other enforcement proceedings resulting therefrom. 63 (b) The Borrower agrees to indemnify each Agent and Bank, their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an "Indemnitee") and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and expenses of any kind, including, without limitation, the reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding (whether or not such Indemnitee shall be designated a party thereto) brought or threatened relating to or arising out of this Agreement or any actual or proposed use of proceeds of Loans hereunder; provided that no Indemnitee shall have the right to be indemnified hereunder for such Indemnitee's own gross negligence or willful misconduct as determined by a court of competent jurisdiction. SECTION 9.04. Sharing of Set-offs. Each Bank agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise (other than any such right against a Shareholder Guarantor), receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it which is greater than the proportion received by any other Bank in respect of the aggregate amount of principal and interest due with respect to any Note held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participations in the Notes held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Notes held by the Banks shall be shared by the Banks pro rata; provided that nothing in this Section shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than its indebtedness hereunder. The Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in a Note, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. SECTION 9.05. Amendments and Waivers. Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Banks (and, if the rights or duties of an Agent are affected thereby, by such Agent); provided that no such amendment or waiver shall, unless signed by all the Banks, (a) increase or decrease the Commitment of any Bank (except for a ratable decrease in the Commitments of all Banks) or subject any Bank to any additional obligation, (b) reduce the principal of or rate of interest on any Loan, or any fees hereunder, (c) postpone the date fixed for any payment of principal of or interest on any Loan, or any fees hereunder or for any scheduled reduction or termination of any 64 Commitment, (d) release the Borrower from its obligations hereunder or the Shareholder Guarantors from their obligations under the Shareholders Guaranties, (e) release all or substantially all of the Collateral, or (f) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes, or the number of Banks, which shall be required for the Banks or any of them to take any action under this Section or any other provision of this Agreement. SECTION 9.06. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or otherwise transfer any of its rights under this Agreement without the prior written consent of all Banks. (b) Any Bank may at any time grant to one or more banks or other institutions (each a "Participant") participating interests in its Commitment or any or all of its Loans. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Borrower and the Agents, such Bank shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Agents shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement. Any agreement pursuant to which any Bank may grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (a), (b), (c), (d) or (e) of the proviso to Section 9.05 without the consent of the Participant. The Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Article 8 with respect to its participating interest. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection (b). (c) Any Bank may at any time, upon five Business Days' written notice to each of the Agents, assign to one or more banks or other institutions (each an "Assignee") all, or a proportionate part (equivalent to an initial Commitment of not less than $2,500,000) of all, of its rights and obligations under this Agreement and the Notes, and such Assignee shall assume such rights and obligations, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D hereto executed by such Assignee and such transferor Bank, with (and subject to) the subscribed consent of the Borrower and the Administrative Agent, which consent shall in each case not be unreasonably withheld; provided that (x) if an Assignee is an affiliate of such transferor Bank or was a Bank immediately prior to such assignment or 65 if the Assignee is a Shareholder Guarantor purchasing Notes pursuant to Section 1(e) of a Shareholder Guaranty, no such consent shall be required and (y) such Bank shall contemporaneously assign to such Assignee an equivalent percentage of loans under the Revolving Credit Agreement. Upon execution and delivery of such instrument and payment by such Assignee to such transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment as set forth in such instrument of assumption, and the transferor Bank shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection (c), the transferor Bank, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if required, a new Note is issued to the Assignee, and the transferor Bank shall provide prompt written notice of such assignment to the Documentation Agent. In connection with any such assignment, the transferor Bank shall pay to the Administrative Agent an administrative fee for processing such assignment in the amount of $2,500. If the Assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Administrative Agent certification as to exemption from deduction or withholding of any United States federal income taxes in accordance with Section 8.04. (d) Any Bank may at any time assign all or any portion of its rights under this Agreement and its Note to a Federal Reserve Bank. No such assignment shall release the transferor Bank from its obligations hereunder. (e) No Assignee, Participant or other transferee of any Bank's rights shall be entitled to receive any greater payment under Section 8.03 or 8.04 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower's prior written consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist. (f) Each Bank shall, upon receipt from a Shareholder Guarantor of an amount equal to all of such Bank's Guaranteed Obligations (as defined in the relevant Shareholder Guaranty) (the "Transfer Payment"), assign to such Shareholder Guarantor the corresponding portion of its rights and obligations under this Agreement and the Notes in accordance with paragraph (c) of this Section 9.06; provided that (i) the consent of the Borrower and the Administrative Agent shall not be required for such assignment and (ii) no such assignment shall be effective until each Bank has received its Transfer Payment from the applicable Shareholder Guarantor. 66 SECTION 9.07. Collateral. Each of the Banks represents to the Agents and each of the other Banks that it in good faith is not relying upon any "margin stock" (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement. SECTION 9.08. Governing Law; Submission to Jurisdiction. This Agreement and each Note shall be governed by and construed in accordance with the laws of the State of New York. The Borrower hereby submits to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in New York City for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. The Borrower irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. SECTION 9.09. Counterparts; Integration; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective upon receipt by the Documentation Agent of counterparts hereof signed by each of the parties hereto (or, in the case of any party as to which an executed counterpart shall not have been received, receipt by the Documentation Agent in form satisfactory to it of telegraphic, telex, facsimile or other written confirmation from such party of execution of a counterpart hereof by such party). SECTION 9.10. Waiver of Jury Trial. EACH OF THE BORROWER, THE AGENTS AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. SECTION 9.11. Confidentiality. Each Bank agrees to take normal and reasonable precautions and exercise due care to maintain the confidentiality of all non-public information provided to it by the Borrower or any of its Subsidiaries by the Agents on the Borrower's or such Subsidiary's behalf in connection with this Agreement or any other Loan Document and neither it nor any of its Affiliates shall use any such information for any purpose or in any 67 manner other than pursuant to the terms contemplated by this Agreement, except to the extent such information (a) was or becomes generally available to the public other than as a result of a disclosure by the Bank, or (b) was or becomes available on a non-confidential basis from a source other than the Borrower, provided that such source is not bound by a confidentiality agreement with the Borrower known to the Bank; provided, further, that any Bank may disclose such information (A) to any other Bank or to the Agents, (B) at the request of any regulatory authority or in connection with an examination of such Bank by any such authority; (C) pursuant to subpoena or other court process; (D) when required to do so in accordance with the provisions of any applicable law; (E) at the express direction of any other agency of any State of the United States of America or of any other jurisdiction in which such Bank conducts its business; and (F) to such Bank's independent auditors and legal counsel. Notwithstanding the foregoing, the Company authorizes each Bank to disclose to any Participant or Assignee (each, a "Transferee") and any prospective Transferee such financial and other information in such Bank's possession concerning the Borrower or any of its Subsidiaries which has been delivered to the Banks pursuant to this Agreement or which has been delivered to the Banks by the Borrower or any of its Subsidiaries in connection with the Banks' credit evaluation of the Borrower and its Subsidiaries prior to entering into this Agreement; provided that such Transferee agrees in writing to such Bank to keep such information confidential to the same extent required of the Banks hereunder. 68 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.

In such capacity I have become familiar with the $100,000,000 Term Credit Agreement (the "Term Credit Agreement") dated as of March 31, 1998 among AMSC, the banks listed on the signature pages thereof, Morgan Guaranty Trust Company of New York, as Documentation Agent, and Toronto Dominion (Texas), Inc., as Administrative Agent. Capitalized terms not otherwise defined herein shall have the meanings set forth in the Term Credit Agreement. This opinion is being rendered to you pursuant to Section 3.1(a) of the Term Credit Agreement. In rendering this opinion, I have examined originals or copies of: 1. the Term Credit Agreement, the Notes and the Security and Pledge Agreement (collectively, the "Loan Documents"); 2. the certificate of incorporation, as amended, of AMSC; 3. the bylaws, as amended, of AMSC; 4. the Certificate of Good Standing with respect to AMSC issued by the Secretary of State of the State of Delaware not earlier than March 20, 1998; 1 5. the Certificate of Good Standing as a Foreign Corporation with respect to AMSC issued by the State Corporation Commission of the Commonwealth of Virginia dated March 20, 1998; and 6. certain resolutions adopted by the Board of Directors of AMSC at a meeting of the Board held on March 19, 1998; upon all of which I have relied. I have not independently verified any factual matters in connection with or apart from my review of the documents referred to above and, accordingly, I do not express any opinion as to matters that might have been disclosed by independent verification. In arriving at the opinions expressed below, I have assumed, and not verified, the authenticity of all documents submitted to me as originals and the conformity to original documents of all documents submitted to me as copies, as well as the due and valid authorization, execution and delivery of all such documents by the appropriate party or parties (other than the Loan Parties), and that each such party (other than the applicable Loan Parties) has adequate power, authority and legal right to enter into such documents to which it is a party and to perform its obligations under such documents to which it is a party. Based solely upon the foregoing and in reliance thereon, and subject to the qualifications, limitations and assumptions set forth herein, it is my opinion that: 1. AMSC is a corporation duly incorporated, validly existing and in good standing under the laws of Delaware, has all corporate powers and all material governmental licenses, authorizations, consents and approvals required to carry on its business as now conducted, and is duly qualified as a foreign corporation, licensed and in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business require such qualification except where the failure to be so qualified would not reasonably be expected to result in a Material Adverse Effect. 2. The execution, delivery and performance by AMSC of the Term Credit Agreement, the Notes and each other Loan Document are within its corporate powers, have been duly authorized by all necessary corporate action and do not and will not: (a) contravene the terms of its certificate of incorporation, bylaws or other organization documents; (b) conflict with or result in any breach or contravention of, or the creation of any Lien under, any indenture, agreement, lease, instrument, Contractual Obligation, injunction, order, decree or undertaking to which such Person is a party (other than Liens under the Security and Pledge Agreement); or (c) violate any Requirement of Law. 2 3. Each Loan Document constitutes the legal, valid and binding obligations or agreements of AMSC, enforceable against it in accordance with its terms. 4. Except as set forth in Section 4.05 of the Disclosure Schedule and for matters arising after the Effective Date which could not reasonably be expected to have a Material Adverse Effect, there are no actions, suits, proceedings, claims or disputes pending, or to the best of our knowledge, threatened or contemplated at law, in equity, in arbitration or before any Governmental Authority, against AMSC or any of its Subsidiaries or any of their respective properties which: (a) purport to affect or pertain to any Loan Document, or any of the transactions contemplated thereby; or (b) if determined adversely to AMSC or any of its Subsidiaries, could have a Material Adverse Effect. No injunction, writ, temporary restraining order or any order of any nature has been issued by any court or other Governmental Authority purporting to enjoin or restrain the execution, delivery and performance of any Loan Document, or directing that the transactions provided for therein not be consummated as therein provided. 5. None of AMSC, any Person controlling AMSC, or any Subsidiary thereof, is (a) an "Investment Company" within the meaning of the Investment Company Act of 1940; or (b) subject to regulation under the Public Utility Holding Company Act of 1935, or, to the best of our knowledge, the Federal Power Act, the Interstate Commerce Act, any state public utilities code or any other Federal or state statute or regulation limiting its ability to incur Indebtedness. 6. Assuming the Agents and the Banks have no knowledge of any adverse claim thereto, the Security and Pledge Agreement, together with possession and retention in the State of New York by the Administrative Agent of stock certificates evidencing the Pledged Stock (as defined in the Security and Pledge Agreement), together with the related duly executed and completed stock powers, creates a valid and perfected security interest in the Pledged Stock under the New York Uniform Commercial Code in favor of the Administrative Agent for the benefit of the Secured Parties (as defined in the Security and Pledge Agreement), subject to the following: the perfection and the continuation of perfection of the Administrative Agent's security interest in proceeds is limited to the extent set forth in Section 9-306 of the New York Uniform Commercial Code. 7. The Security and Pledge Agreement is in acceptable legal form for the creation of enforceable security interests under the Uniform Commercial Code of the State of New York. The financing statements attached hereto are in appropriate form for filing with the filing offices specified thereon. To the extent that a security interest in the Collateral (as defined in the Security and Pledge Agreement) may be perfected by the filing of a financing statement, the security interest in such Collateral will be perfected upon the filing of such financing statements in such filing offices. 3 The opinions set forth in this paragraph 7 are subject to the further qualification that I express no opinion as to (i) AMSC's rights in or title to any Collateral; and (ii) the priority of the Administrative Agent's security interest in the Collateral, and the opinions set forth in paragraphs 6 and 7 are subject to the further qualification that I express no opinion as to (i) the enforceability of provisions in the Security and Pledge Agreement as to self-help and non-judicial remedies, (ii) whether the procedures relating to the sale or disposition of the Collateral in the Security and Pledge Agreement would meet applicable requirements for a commercially reasonable disposition, and (iii) the enforceability of the provisions in the Security and Pledge Agreement relating to or purporting to limit the Administrative Agent's duty with respect to the Collateral. The foregoing opinions are subject to the following assumptions and qualifications: (a) The opinions set forth in paragraph 3 are subject to the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally and to the possible judicial application of foreign laws or governmental action affecting the enforcement of creditors' rights. (b) The opinions set forth in paragraph 3 are subject to the further qualification that the enforceability of the obligations of AMSC under the Loan Documents are subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). Such principles of equity are of general application and, in applying such principles, a court, among other things, might not allow a creditor to accelerate the maturity of a debt upon the occurrence of a default deemed immaterial or might decline to order that a covenant be performed. Such principles applied by a court might include, among other things, a requirement that creditors act with reasonableness and good faith. Such a requirement might be applied, among other situations, to the provisions of any Loan Document requiring the payment of an indemnity or compensation to any party thereto or purporting to authorize conclusive determinations by any party thereto. (c) With respect to my opinion in paragraph 3 hereof, I express no opinion as to whether the courts of a jurisdiction other than the State of New York would give effect to the choice of New York law as governing the agreements as to which I express an opinion in paragraph 3. (d) The foregoing opinions are limited to the laws of the State of New York, the General Corporation Law of the State of Delaware, the laws of the Commonwealth of Virginia and the Federal law of the United States (except as noted below), and I do not express any opinion herein concerning any other law (including, without limitation, any such other law of any jurisdiction wherein 4 any party to any of Loan Document may be located or deemed located or wherein enforcement of any such documents may be sought). I do not express any opinion as to any matters arising under the Communications Act of 1934, as amended, or any rules or regulations of the Federal Communications Commission. I do not express any opinion as to any matters (including Governmental Approvals) relating to international law, including compliance by any Loan Party with treaties involving the International Maritime Satellite Organization, the International Telecommunications Satellite Organization and the International Telecommunication Union. I am not a member of the Bar of the State of Delaware and insofar as the opinions expressed herein relate to matters of the General Corporation Law of the State of Delaware, I have relied on the latest standard compilations of statutes available to me. The opinions herein are rendered as of the date of this opinion, and I assume no obligation to revise or supplement this opinion at any date subsequent hereto. The opinions set forth above relate solely to the matters as to which my opinion has been requested by you, and you must judge whether the matters addressed herein are sufficient for your purposes. I do not express any opinion as to any other matters. This opinion is rendered to the Documentation Agent and is solely for its benefit, for the benefit of the Shareholder Guarantors, and for the benefit of any Bank party to the Term Credit Agreement in connection with the above transaction. This opinion may not be relied upon by the Documentation Agent for any other purpose, or furnished to, quoted to or relied upon by any other Person other than any Bank or Shareholder Guarantor referred to in the immediately preceding sentence, for any purpose without my prior written consent. It is not to be filed with or furnished to any Governmental Authority or other Person in either case without my prior written consent. Very truly yours, /s/Randy S. Segal Randy S. Segal General Counsel 5 EXHIBIT C -- Opinion of Special Counsel for the Agents OPINION OF DAVIS POLK & WARDWELL, SPECIAL COUNSEL FOR THE AGENTS March __, 1998 To the Banks and the Agents Referred to Below c/o Morgan Guaranty Trust Company of New York, as Documentation Agent 60 Wall Street New York, New York 10260 Dear Sirs: We have participated in the preparation of the $100,000,000 Term Credit Agreement (the "Term Credit Agreement") dated as of March 31, 1998 among American Mobile Satellite Corporation, a Delaware corporation ("AMSC"), the banks listed on the signature pages thereof (the "Banks"), Morgan Guaranty Trust Company of New York, as Documentation Agent, and Toronto Dominion (Texas), Inc., as Administrative Agent (collectively, the "Agents"), and have acted as special counsel for the Agents for the purpose of rendering this opinion pursuant to Section 3.01 of the Term Credit Agreement. Terms defined in the Term Credit Agreement are used herein as therein defined. We have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as we have deemed necessary or advisable for purposes of this opinion. Upon the basis of the foregoing, we are of the opinion that assuming that the execution, delivery and performance by AMSC of the Term Credit Agreement and the Notes are within its corporate powers and have been duly authorized by all necessary corporate action, the Term Credit Agreement constitutes a valid and binding agreement of AMSC and each Note constitutes a valid and binding obligation of AMSC, in each case enforceable in accordance 1 with its terms except as may be limited by bankruptcy, insolvency or similar laws affecting creditors' rights generally and by general principles of equity. We are members of the Bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York. In giving the foregoing opinion, we express no opinion as to the effect (if any) of any law of any jurisdiction (except the State of New York) in which any Bank is located which limits the rate of interest that such Bank may charge or collect. This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by any other person without our prior written consent. Very truly yours, 2 EXHIBIT D -- Assignment and Assumption Agreement ASSIGNMENT AND ASSUMPTION AGREEMENT AGREEMENT dated as of _________, 19__ among [NAME OF ASSIGNOR] (the "Assignor"), [NAME OF ASSIGNEE] (the "Assignee"), AMERICAN MOBILE SATELLITE CORPORATION (the "Borrower") and TORONTO DOMINION (TEXAS), INC., as Administrative Agent (the "Agent").

Upon the execution and delivery hereof by the Assignor, the Assignee, [the Borrower and the Agent] and the 1 payment of the amounts specified in Section 3 required to be paid on the date hereof (i) the Assignee shall, as of the date hereof, succeed to the rights and be obligated to perform the obligations of a Bank under the Credit Agreement with a Commitment in an amount equal to the Assigned Amount, and (ii) the Commitment of the Assignor shall, as of the date hereof, be reduced by a like amount and the Assignor released from its obligations under the Credit Agreement to the extent such obligations have been assumed by the Assignee.
