If the Borrower (or the Company, if making a payment on behalf of the Borrower) shall be required by law to make any deduction or withholding in respect of Taxes from any payment hereunder, including payments made under this subsection 3.01(a), the sum payable shall be increased to such sum as will result in the receipt by the Creditor after such deduction or withholding, of the amount that would have been received if such deduction or withholding had not been required.

     (b)  The Borrower (and the Company if making any payment on behalf of the Borrower) agrees to pay any Taxes imposed on or with regard to the execution, formalization, registration, recordation or perfection of any of the Operative Documents or any other documentation contemplated hereunder or delivered pursuant hereto.

Amounts payable hereunder shall be due seven (7) days after invoice therefor.

     (b)  The protection of subsection 3.02(a) hereof shall apply to voluntary compliance by the Creditor with restraints, guidelines or policies not having the force of law and shall apply if the Creditor shall comply with any law, regulation or condition irrespective of any possible contention of invalidity or non-applicability thereof.

     (d)  In the event of any such change or request as is contemplated by subsection 3.02(a) hereof the Creditor will use reasonable endeavors to mitigate the effect or likely effect of such change or request by transferring the LIBOR Advances to another jurisdiction or otherwise; provided, however, that the Creditor shall be under no obligation to transfer the LIBOR Advances to another jurisdiction or to take any other action to mitigate the effect or likely effect of such change or request if, in the reasonable opinion of the Creditor, such transfer or other action could reasonably be expected to have an adverse effect upon the Creditor, whether as a result of taxes, credit policies, political considerations or otherwise; provided, further, that the Borrower shall reimburse the Creditor on demand for all expenses (including attorney’s fees) incurred by the Creditor in effecting such transfer (if such transfer is requested by the Borrower) and the Creditor shall have no obligation to effect any such transfer unless the Creditor is satisfied that it will not suffer any adverse consequences as a result of such transfer for which it has not been indemnified by the Borrower. If the Creditor is entitled to reimbursement under this subsection 3.02(d) for any cost, the Creditor shall deliver to the Borrower a statement of the nature and amount of such cost which statement shall constitute prima facie evidence as to the amount due to the Creditor under this subsection 3.02(d).

     (e)  If the Borrower elects (which election shall be irrevocable) by giving at least two (2) Business Days prior written notice to the Creditor, the Borrower may, without penalty or premium, prepay to the Creditor any outstanding Advances on any Interest Payment Date applicable to such Advances with respect to which the Borrower has received a claim under this Section 3.02 together with accrued interest thereon and all other sums due to the Creditor (including amounts accrued or due under this Section 3.02).

     (b)  In addition to such remedies as are provided for in this Agreement, the Intercreditor Agreement and the other Credit Documents, the Creditor’s remedies upon the occurrence and during the continuance of an Event of Default shall include (i) a right to apply or require the Borrower to apply for any necessary orders or licenses in connection with the operation or abandonment of the System, the Telecommunications Business or any part thereof, and (ii) to the extent permitted by law, a right to have a receiver appointed by a court of competent jurisdiction in order to manage, protect and preserve the System, the Telecommunications Business and all other equipment, property and other collateral and to continue the operation of the business of the Borrower, and to collect the revenues and profits thereof and apply the same to the payment of all expenses and other charges of such receivership until the sale or other final disposition of the Collateral, including without limitation, the System, the Telecommunications Business and such equipment, property and assets mortgaged or pledged to the Creditor.

     (c)  The Borrower agrees, in case an Event of Default shall be existing and upon the Collateral Agent’s request to the extent permitted under the Intercreditor Agreement, to assemble, at its expense, all equipment constituting a part of the Collateral at a convenient place acceptable

-82-

to the Collateral Agent and to pay all the Collateral Agent’s costs of collection of all amounts due, and enforcement of all rights hereunder, including reasonable attorney’s fees and legal expenses, and expenses of any repairs to any realty or other property to which any of such equipment may be affixed or be part. Upon an Event of Default, the Collateral Agent may, only to the extent permitted under the Intercreditor Agreement, to the fullest extent permitted by applicable law, without notice, advertisement, hearing or process of law of any kind (i) to the extent permitted by law, enter upon any premises where any of the equipment constituting part of the Collateral may be located and take possession of and remove such equipment, (ii) sell any or all of such equipment, free of all rights and claims of the Borrower therein and thereto, at any public or private sale, and (iii) to the extent permitted by law, bid for and purchase any or all of such equipment at any such sale.

     (d)  The Collateral Agent may, only to the extent permitted under the Intercreditor Agreement, upon the occurrence and during the continuance of an Event of Default, without demand and without advertisement or notice, all of which the Borrower waives at any time or times, sell and deliver, any or all Collateral held by or for it at public or private sale, for cash, upon credit, or otherwise, at such prices and upon such terms as the Collateral Agent deems advisable, in its sole discretion and/or collect or enforce the collection of, the Collateral; provided, however that method, manner, time, place and terms of any sale must be commercially reasonable and the Collateral Agent shall make a reasonable attempt to receive fair market value for any Collateral subject to such sale. In addition to all other sums due to the Collateral Agent, the Borrower shall pay the Collateral Agent all reasonable costs and expenses incurred by the Collateral Agent including attorney’s fees and court costs, to obtain, liquidate and/or enforce payment of Collateral obligations, or in the prosecution or defense of any action or proceeding against the Creditor concerning any matter arising out of or connected with the Credit Documents or the Collateral.

     (e)  In connection with the enforcement by the Collateral Agent of any remedies available to it as a result of any Event of Default, the Borrower, the Company and NII shall join and cooperate fully with the Creditor and the Collateral Agent and with any receiver referred to above and with the successful bidder or bidders at any foreclosure sale when any of these entities files an application (including the furnishing of any additional information that may be required in connection with such application), with any necessary Governmental Authorities, requesting their prior approval of (i) the operation or abandonment of all or any portion of the System or the Telecommunications Business and (ii) the assignment or transfer to such entity of all licenses, authorizations and permits issued to the Borrower or any other Credit Party by such Governmental Authorities with respect to the System, the Telecommunications Business and the operation thereof.

-83-

repayable to the Creditor with interest thereon from the date of such advance until paid at the Post-Default Rate.

     (h)  The Creditor shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral in its possession if it takes such action for that purpose as the Borrower requests in writing, but failure of the Creditor to comply with any such request shall not of itself be deemed a failure to exercise reasonable care, and no failure of the Creditor to preserve or protect any rights with respect to such Collateral against prior parties, or to do any act with respect to the preservation of such Collateral not so requested by the Borrower, shall be deemed a failure to exercise reasonable care in the custody or preservation of such Collateral.

     (i)  All moneys received by the Collateral Agent pursuant to any right given or action taken under Section 11 of this Agreement shall be applied in accordance with the Intercreditor Agreement.

     (j)  In addition to its rights with respect to the Collateral hereunder, upon the occurrence of an Event of Default, the Creditor may seek payment of the outstanding obligations from NII, the Company, the Foreign Affiliates or Other Credit Parties in accordance with the Intercreditor Agreement. The Collateral Agent shall not, however, proceed to liquidate the Collateral hereunder and under the Guaranties in excess of the amount which the Creditor reasonably determines will be necessary to satisfy the outstanding obligations which have become due and payable, provided, that the Collateral Agent may continue so to liquidate until all outstanding obligations which have become due and payable have been satisfied in full.

     (k)  The Creditor may exercise any and all of its remedies under the Security Documents or the Guaranties contemporaneously or separately from the exercise of any other remedies hereunder or with respect to any Collateral in accordance with the Intercreditor Agreement.

     Section 11.03. Cumulative Rights. No failure or delay on the part of the Creditor in exercising any right, power or remedy accruing to it upon any breach or default of the Borrower under any of the Credit Documents shall impair any such right, power or remedy nor shall it be construed as a waiver of any such breach or default thereafter occurring, nor shall a waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring, nor shall any single or partial exercise of any such right or power preclude any other or further exercise thereof or the exercise of any other right or power hereunder. To the fullest extent permitted by law, all remedies, either under the Credit Documents or by law otherwise afforded the Creditor shall be cumulative and not alternative.

     Section 11.04. Waiver of Demand. DEMAND, PRESENTMENT, PROTEST AND NOTICE OF DEMAND, PRESENTMENT, PROTEST AND NONPAYMENT ARE HEREBY WAIVED TO THE EXTENT PERMITTED BY LAW BY THE BORROWER. THE BORROWER ALSO WAIVES THE BENEFIT OF ALL VALUATION, APPRAISAL AND EXEMPTION LAWS TO THE EXTENT PERMITTED BY LAW.

     Section 12.10. Proposed Consolidation. The Creditor and the Company agree that the Proposed Consolidation may be consummated, so long as such consummation is in full compliance with the conditions set forth in Section 9.05 hereof.

     Section 12.11. Confidentiality. Each of the Borrower, the Company, NII and the Creditor hereby agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates, directors, officers, employees and agents, accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to the execution and delivery of an agreement containing provisions substantially the same as those of this Section 12.11, to any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement, (g) with the consent of the other parties hereto, or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 12.11 or (ii) becomes available to such party on a non-confidential basis from a source other than the other parties hereto.

Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

     Section 12.12. Term of Agreement. This Agreement shall continue in full force and effect, and be binding upon the Borrower, until all of the Obligations have been fully and indefeasibly paid and performed whereupon this Agreement shall terminate. Notwithstanding the foregoing, all the indemnification provisions shall survive and all other provisions which, by their terms, survive termination shall so survive.
