accordance with, Sections 1 through 5 of Schedule D (Charges) hereto. Except as otherwise provided in this clause (g) below, Amdocs shall be required to complete all Phases with respect to the Initial Release in an amount of hours that is less than or equal to the Not-to-Exceed Amount. Further, the Parties agree and acknowledge that the Not-To-Exceed Amount includes [**] ([**]) Customization hours relating to Amdocs' Ensemble module known as Flexible Bill Formatter to be used with the TRIS Billing System. Amdocs shall be permitted to charge Nextel in excess of the Not-to-Exceed Amount to complete the Initial Release in the event that either (i) Nextel adds requirements for the Initial Release subsequent to its acceptance of the DFS (net of hours to be saved by Amdocs, if any, due to changes to the requirements contained in the DFS) or (ii) there are delays caused by Nextel, as determined pursuant to Section 1.7(c)and in such cases, only in the amount of the agreed upon number of hours to complete such additional requirements or the number of extra hours incurred by Amdocs, to the extent directly resulting from Nextel's delays, as the case may be. The Parties further agree that, in the event that Nextel elects to defer to an Additional Release, Amdocs' performance of any requirements included in the Requests or the DFS for the Initial Release, Amdocs shall be permitted to charge Nextel no more than the number of hours specified in the Requests or DFS with respect to each such deferred requirement; provided that such Additional Release is a Major Additional Release and is scheduled in the applicable Project Plan to go into production on or before December 31, 2002. To the extent that Amdocs uses fewer than the Not-To-Exceed Amount to complete the Initial Release, the number of hours equal to the difference between the Not-To-Exceed Amount and the actual number hours used to complete the Initial Release (the "Unused Initial Release Hours") may be carried forward by Nextel and applied against any charges for Additional Customization Services performed either for the benefit of Nextel or any Nextel Customer. To the extent that Amdocs uses more than the Not-To-Exceed Amount to complete the Initial Release, Prepaid Customization Hours may be applied as provided in Section 1.2.1(h) (Statements of Work); provided that Amdocs shall not be permitted to charge Nextel for hours exceeding the Not-To-Exceed Amount except under the conditions set forth in clauses (i) or (ii) above and with the prior written approval of Nextel. To facilitate the measurement of any Unused Initial Release Hours, Amdocs shall (y) prepare a functional breakdown of how Amdocs hours are expected to be used and (z) continuously track and document the actual number of hours expended for each such functional category until it has completed the Initial Release and shall, upon Nextel's request, provide a monthly report thereon in a format to be agreed upon by the Parties. (h) As set forth in Schedule D (Charges), one component of the Maintenance Services is a specified number of hours that Nextel may apply towards Customization services performed for either the benefit of Nextel or any Nextel Customer (the "Prepaid Customization Hours"). Following the completion of the Initial Release, Nextel may request that Amdocs use the Prepaid Customization Hours other than as provided for in Schedule D (Charges) as follows: (i) in any applicable calendar year, Nextel may use [**] the Prepaid Customization Hours allocated to the forthcoming year; and (ii) in any applicable calendar year, Nextel may use [**] amount of unused Prepaid Customization Hours allocated to previous years. In the event Nextel requests Amdocs to use Prepaid Customization Hours as provided for in clause (i) above, the respective payment for such transferred hours shall be made by Nextel on the first business day (usually January 2nd) of the calendar year to which such hours were originally allocated. At the end of the Term, whether due to expiration of the Term or NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 4 -

termination by either Party, Amdocs shall pay to Nextel an amount equal to the number of unused Customization hours, i.e., any Unused Initial Release Hours and any unused Prepaid Customization Hours (provided that Nextel has paid Amdocs the Maintenance Fee associated with such unused Prepaid Customization Hours) calculated at the then current rate for such hours, provided that Amdocs shall be entitled to deduct from such payment all undisputed amounts owing by Nextel, but that have not yet been paid, pursuant to the terms hereof. Such refund is not intended to compensate Nextel for any breach or default by Amdocs under this Agreement, nor to constitute penalties, damages, liquidated damages, or other compensation for any such breach or default. In no event shall such refund be construed as Nextel's sole and exclusive remedy with respect to any failure of Amdocs to perform any required Customizations. 1.2.2 ADDITIONAL RELEASES The Parties will hold regular, detailed discussions regarding the scope and timetable of any releases of the Customized Product subsequent to the Initial Release (each an "Additional Release" and collectively with the Initial Release, the "Release" or the "Releases") to be developed in any certain calendar year.

In exercising its discretion to approve an Additional Data Center, the Parties agree and acknowledge that it is Nextel's reasonable preference that the Services generally be performed in the United States. In addition, Amdocs acknowledges and agrees that support activities and Maintenance Services often require communication made extremely difficult if Amdocs personnel performing such Services are located outside the United States. In the event that Amdocs elects to perform certain of the Services outside the United States (including those cases where Nextel has approved an Additional Data Center located outside the United States), (i) no CPSs will be adjusted due to such Services being performed outside of the United States and (ii) Amdocs shall ensure that (A) the Services shall be performed either less expensively or more efficiently outside the United States and (B) Nextel shall suffer no adverse consequence from the Services being performed outside the United States. 1.9 NON-EXCLUSIVITY [**] during the Term; provided that Nextel shall remain responsible for all of the obligations and commitments specifically applicable to it hereunder (including any minimum Monthly Subscriber Fee commitment). 1.10 NEXTEL PARTIES (a) The Parties agree that [**] (i) [**] wireless telecommunications services [**] and (ii) in [**] such telecommunications services, [**] contained in the Agreement, [**] in accordance with the terms hereof.

At all Nextel facilities, Nextel will provide Amdocs reasonable access to and use of Nextel's voice and data telecommunications equipment and NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 9 -

telecommunications lines (for use with communications within the United States), including printers, terminals, and cabling. In addition, Nextel shall provide Amdocs with a data line connected to those Amdocs' Data Centers, and to a development center designated by Amdocs; provided that such Data Centers and development center are located in the United States. Nextel will give Amdocs access to such facilities twenty four (24) hours a day, seven days a week; provided that: (i) Amdocs complies with Nextel's security requirements and (ii) Amdocs schedules such access so as to minimize any impact on the running of Nextel's business. Nextel will be responsible for leasehold improvements at Nextel's facilities that the Parties agree are required for Amdocs to provide the Services. 3. RELATIONSHIP MANAGEMENT 3.1 STEERING COMMITTEE The Parties shall establish and maintain a Steering Committee, which shall be composed of an equal number of Amdocs' representatives and Nextel's representatives. The initial representatives and their positions with Nextel and Amdocs, respectively, are set forth in Schedule F (Steering Committee). The members appointed by either Party may be replaced at the discretion of such Party. The general responsibilities of the Steering Committee shall be: (i) to monitor the performance of the Services; (ii) to analyze and attempt to resolve matters referred by the Program Managers; and (iii) to consider and approve or reject amendments to this Agreement. The Steering Committee shall meet as frequently as requested by either Nextel or Amdocs, not to exceed once every thirty (30) days, with at a minimum, ten (10) business days' prior written notice, to discuss the status of the Services and significant events that have occurred since the previous meeting. 3.2 KEY PERSONNEL AND PROGRAM MANAGER 3.2.1 AMDOCS' KEY PERSONNEL AND PROGRAM MANAGER Each of Amdocs' Key Personnel shall have the functions assigned to him or her as set forth in Schedule G (Key Personnel and Program Manager).

by Amdocs or by the employee, Amdocs shall obtain, where required as aforesaid, Nextel's prior written consent [**] in advance of, and shall always coordinate with Nextel, any reassignment resulting in alteration or reduction of time expended by personnel in performance of Amdocs' duties under this Agreement. If any one of Amdocs' Key Personnel is reassigned and therefore becomes unable to perform the functions or responsibilities assigned to him or her, or is no longer employed by Amdocs, Amdocs shall promptly replace such person with another person at least as well qualified who shall promptly become knowledgeable regarding the Services. Nextel shall not be assessed any charges for any Services performed by, or otherwise with respect to, such person replacing Key Personnel (or any replacement made pursuant to Section 3.2.6 (Individual Performance)) during his or her first two weeks as the replacement person. For the avoidance of doubt, Amdocs may promote any of its Key Personnel, provided that any such promotion does not result in Amdocs violating the above restriction on reassigning its Key Personnel.

Nextel's Program Manager shall act as the primary liaison between Nextel and Amdocs' Program Manager and shall have overall responsibility for directing all of Nextel's activities hereunder and shall be vested with all necessary authority to fulfill that responsibility, excluding approval of any amendment to this Agreement, which may not be made without the express written consent of all of Nextel's Steering Committee members. 3.2.3 ADDITIONAL PERSONNEL REQUIREMENTS In addition to Amdocs' Key Personnel, Amdocs shall make available such additional professionals as are necessary to properly perform the Services. 3.2.4 NON-SOLICITATION OF EMPLOYEES During the Term and for twelve (12) months thereafter, neither Party shall, without the other Party's prior written consent, which may be withheld in such Party's sole discretion, directly or indirectly solicit any employee of the other Party whose duties and responsibilities include: (i) participation, directly or indirectly, in the performance of this NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 11 -

Agreement; or (ii) the performance of other information or technology services; to leave the other Party's employ in order to accept employment with the soliciting Party, its Affiliates, or contractors or any other Person. 3.2.5 RESPONSIBILITY OF PERSONNEL Each Party shall be responsible for the management, direction, control, supervision and compensation of its own employees. 3.2.6 INDIVIDUAL PERFORMANCE Notwithstanding Section 3.2.1 (Amdocs' Key Personnel and Program Manager), if Nextel believes that the performance or conduct of any person employed or retained by Amdocs to perform the Services is, for any reason, unsatisfactory to Nextel or is not in compliance with the provisions of this Agreement, Nextel may so notify Amdocs and upon any such notice Amdocs shall promptly remedy the performance or conduct of such person, or, at Nextel's reasonable request, replace such person with another person reasonably acceptable to Nextel. 3.3 DEDICATED HARDWARE In the event that Amdocs shall provide services to any Third Party using hardware with which Amdocs provides Services to Nextel hereunder, such use with such Third Party shall be subject to all relevant confidentiality and security related provisions of this Agreement. 3.4 MODEL OFFICE Promptly after execution of this Agreement, Amdocs shall install and maintain, at a Nextel facility to be designated by Nextel, at no charge or expense, a single copy of the "Model Office" version of the Generic Product and, at no charge or expense, from time to time Amdocs shall make all updates and upgrades thereto.

3.6 ACCEPTANCE TESTING 3.6.1 SOFTWARE COMPONENT TESTING (a) Amdocs shall design, develop and execute the Unit Testing, System Testing, Conversion Testing, and Performance Testing of the Customized Product, all components thereof and any other software to be provided hereunder in connection with each Release of the Customized Product. The Parties shall conduct the Testing Activities (as defined below) in accordance with the process set forth below in order to verify compliance of the Customized Product with the applicable Detailed Functional Specification and Amdocs shall provide such assistance and cooperation to Nextel as is reasonably requested by Nextel in connection with Interface Testing and User Acceptance Testing in accordance with this Agreement, including Schedule B (Roles and Responsibilities) (collectively, the "Amdocs Testing Activities"). With the reasonable assistance of Amdocs, Nextel shall conduct Interface Testing and User Acceptance Testing and assist Amdocs with System Testing, Conversion Testing, and Performance Testing of the Customized Product (collectively, the "Nextel Testing Activities," and collectively with the Amdocs Testing Activities, the "Testing Activities"). For Amdocs Testing Activities, Nextel shall provide Amdocs, at least [**] prior to the commencement of the User Acceptance Testing referred to herein below, with all of the test cases to be used by Nextel for the Nextel Testing Activities. For all Testing Activities, Amdocs will provide Nextel, upon prior request, with access to any test case databases, test cases executed, defect logs, test entrance and exit criteria, access to Amdocs' data extraction tool, and any relevant test result documentation. (b) Nextel reserves the right to observe and verify Amdocs' performance of and results from all Amdocs' Testing Activities (except Unit Testing), including review of test cases, test execution and test results of the software components contained or to be contained in the Customized Product, including Customizations pursuant to the applicable Detailed Functional Specification ("Software Components"). Upon Amdocs' notification to Nextel that Amdocs has completed Unit Testing, System Testing, Conversion Testing, and Performance Testing of all of the Software Components and such Software Components have been verified in writing by Nextel to be free of known defects, or Nextel and Amdocs mutually agree in writing to proceed with User Acceptance Testing notwithstanding the existence of known defects, Nextel shall promptly begin the User Acceptance Testing of such Software Components in environments using actual converted data and test generated data, and using business scenarios to be developed by the Parties during the applicable Detailed Program Design Phase, to determine whether each Software Component performs as warranted in Section 10 (Warranty). Nextel shall be permitted to add any additional business scenarios after the end of the applicable Detailed Program Design Phase to account for any changes in functionality or negative test conditions. No later than [**] prior to User Acceptance Testing, Amdocs shall provide to Nextel the detailed test scripts used in System Testing consisting of the detailed run books, test calendars, and any other test case material that is used as a part of System Testing. Further, Amdocs shall provide training on the Customized Product for Nextel personnel conducting User Acceptance Testing. During each cycle of User Acceptance Testing, if Nextel determines that a Software Component, or the Customized Product as a whole, has a material defect or is not performing according to the Specifications, or does not perform as warranted in NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 13 -

Section 10.3(g) (Warranty), Nextel shall report the discrepancies to Amdocs. In the event that User Acceptance Testing halts due to deficiencies uncovered during the User Acceptance Testing, Amdocs must correct the deficiencies in the time frames specified for the highest priority correction in Section 2.1 of Appendix II (Mean Time to Repair) in Schedule C (Creditable Performance Specifications (CPSs)). In the event that User Acceptance Testing does not halt and continues to run, Amdocs shall correct the errors or defects and provide corrected Software Components within [**] after the end of the cycle of User Acceptance Testing. Nextel may re-run cycles of User Acceptance Testing until such a time that Nextel is satisfied with the quality of the Software Component. Nextel's undertaking of User Acceptance Testing does not imply acknowledgement of defect-free software, nor does it limit Nextel's ability or right to later discover and report product defects. Upon Nextel's verification that the Software Components are free of known defects or Nextel's determination to proceed with known defects, Nextel shall notify Amdocs in writing that "Initial Acceptance" of such Software Component (or the Customized Product, as the case may be), has occurred. Nextel's determination to proceed with known defects shall not limit Amdocs' obligation to timely correct such defects. (c) Upon Initial Acceptance by Nextel of all Software Components contained in a Release of the Customized Product, Nextel shall begin testing such Software Components in Pilot Testing. The structure, goals and success criteria of the Pilot Testing will be as set forth and mutually agreed upon by the Parties and set forth in the applicable Detailed Program Design. (d) Upon successful completion of the Pilot Testing (during which all errors or defects, if any which have been detected in the Customized Product are cured by Amdocs), and upon a subsequent "go live" decision by Nextel, Nextel shall begin to use the Customized Product, in a production environment. Nextel shall be deemed to have issued its "Final Acceptance" of the applicable Release of the Customized Product upon Amdocs' correction of any material errors detected and identified to Amdocs (i) prior to the "go live" date; and (ii) during the period commencing on the "go live" date and ending on the later of: (x) [**] subsequent to such "go live" date and (y) [**] after the completion of the first billing cycle using the applicable Release of the Customized Product. For purposes of clause (ii) of this Section 3.6.1(d), material errors are Priority 1 and Priority 2 Issues as defined in Schedule C (Creditable Performance Specifications (CPSs)). Subsequent to "Final Acceptance," Amdocs shall be required to correct any errors in the applicable Release of the Customized Product in accordance with this Agreement, including the Schedules hereto. 3.6.2 NON SOFTWARE ACCEPTANCE Each material deliverable required to be provided for Nextel pursuant to a Statement of Work hereunder that is not a Software Component shall also be subject to acceptance by Nextel as provided below. The Parties shall establish specific approval criteria with respect to each material non-software deliverable hereunder, at least [**] prior to the scheduled delivery date of such non-software deliverable. However, the Parties agree that acceptance criteria for the DPD for the Initial Release shall be established by the Parties prior to October 16, 2000. Nextel shall review each such deliverable under any such specifically established approval criteria and within the time established for that deliverable pursuant to the applicable Statement of Work (or, if none is so established then within a reasonable time). Upon NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 14 -

completion of the reviews, Nextel shall notify Amdocs in writing of Nextel's approval (an "Approving Notice") or non-approval (a "Non-Approving Notice") of the deliverable. Non-Approval may be determined only due to a failure to meet the deliverable specific approval criteria therefor, or, in the absence of such deliverable specific approval criteria, a material defect. In the event that Nextel does not send to Amdocs an Approving Notice or a Non-Approving Notice within [**] of delivery, the deliverable shall be deemed accepted. If the deliverable is not approved, Nextel shall include in the Non-Approving Notice a statement of the material defect or the deliverable specific approval criteria that were not met. Amdocs agrees that it will correct any identified material defects or failures of a non-approved deliverable to meet the deliverable specific approval criteria promptly, and in any event, within any time frame established in the applicable Statement of Work and that [**] to effect such correction. Upon delivery of the revised deliverable, the review process described above shall recommence with respect to all aspects of such deliverable that were to have been corrected and any other aspects that may have been affected as a result of such corrections. 3.6.3 EFFECT OF REVIEWS Notwithstanding any opportunity for Nextel to inspect any intermediate deliverables, no testing pursuant to Section 3.6 (Acceptance Testing) or Approving Notice shall constitute a waiver of or otherwise relieve Amdocs from its obligations hereunder, including, without limitation pursuant to the warranties of Section 10 (Warranty) hereof and no Approving Notice with respect to an intermediate deliverable shall obligate Nextel with respect to, or constitute, approval or acceptance of the Customized Product. For the avoidance of doubt, the provisions of this Subsection 3.6.3 (Effect of Reviews) shall not affect the acceptance of the Customized Product in accordance with the provisions of Section 3.6.1 (Software Component Testing). 3.7 DISPUTE RESOLUTION 3.7.1 PROBLEMS In the event of any dispute under or in relation to this Agreement (including but not limited to a dispute regarding the subject matter of Section 3.6 (Acceptance Testing), any Statement of Work or any damages claimed by one Party from the other Party, the Program Managers shall discuss and make an effort to resolve such dispute at or prior to the next Steering Committee meeting, and for at least [**]. If the Program Managers shall have executed a written resolution of the dispute, each Party shall begin performance in accordance with such resolution, provided that no agreement of the Program Managers may amend or modify the terms of this Agreement without the concurrence of the Steering Committee.

tasks and responsibilities (including any Milestone, if any) and identification of individuals performing services. All invoices shall be denominated in currency of the United States of America. 4.2.5 PERFORMANCE CREDITS AND BONUSES Nextel will be entitled to Performance Credits, and Amdocs shall be entitled to bonuses, in accordance with Schedule C (Creditable Performance Specifications (CPSs)), in respect of Amdocs' actual performance of Services as measured against the CPSs. It is understood that Performance Credits are intended to reflect, to some extent, the diminished value of Amdocs' Services in such events. Performance Credits are not intended to compensate Nextel for any breach or default by Amdocs under this Agreement, nor to constitute damages, liquidated damages, or other compensation for any such breach or default. In no event shall Performance Credits be Nextel's sole and exclusive remedy with respect to any failure of Amdocs to comply with applicable CPSs; provided that any monetary award granted to Nextel with respect to such failure shall be reduced by, but shall not be limited to, any Performance Credit paid by Amdocs with respect to such failure. 4.2.6 PAYMENTS (a) Except for amounts reasonably disputed in good faith (which shall be dealt with as provided below), Nextel shall pay all invoices properly issued no later than the [**] (the "Due Date") after receipt thereof.

Amdocs shall be permitted to charge Nextel Interest on any undisputed amount payable under this Agreement in the event such undisputed amount is not paid within [**] of the Due Date, on the monthly invoice immediately following the month of the invoice including such unpaid amount, such Interest to be computed from the Due Date to the date of payment. (c) Each of Nextel and Amdocs shall appoint one member of a joint committee (the "Joint Committee") established to deal with the issue of Amdocs' invoices and any disputed amounts payable under this Agreement. The first members of the Joint Committee will be Nextel's Director of Business Systems Overhaul Project and Amdocs' Vice President for the Customer Care and Billing Project. The committee members will agree on the format of Amdocs' invoices and the additional information or documentation, if any, required to support such invoices. (d) Upon receiving an Amdocs invoice, Nextel shall, as soon as reasonably practicable, review the invoice to verify whether there are any disputed amounts in NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 22 -

the invoice; provided that Nextel shall retain its right to dispute any amounts contained in such invoice that it discovers later, including subsequent to the payment of such invoice. In the event Nextel is of the opinion that any invoice contains a disputed amount (whether or not the disputed amount has already been paid by Nextel), it shall promptly prepare a detailed memorandum explaining the basis for the dispute and gather reasonable documentation and information, if possible, to substantiate it. Nextel shall then, without further delay, bring such material to the attention of the Joint Committee who shall use all reasonable efforts to resolve the matter of the disputed amount within [**]. If such a resolution cannot be reached within the above period (or any other period mutually agreed upon by the Parties), the matter shall be immediately presented by the Joint Committee to Nextel's Chief Information Officer or Nextel's Chief Operations Officer for determination as to whether the amount in question (or any part thereof) is disputed or not. Provided that the procedure set forth in this clause (d) has been followed and that such person determines that the amount is disputed and was initially invoiced on or after the date that is [**] prior to the date of the invoice from which such disputed amount is being withheld, Nextel shall have the right to withhold such amount from such invoice and the matter shall be resolved in accordance with the dispute resolution procedure specified in Section 3.7 (Dispute Resolution) as if the matter has not been resolved by the Program Managers; provided, however, that nothing herein shall be construed to restrict or limit in any way Nextel's right to terminate this Agreement, at any time, in accordance with the provisions of Section 5 (Term, Renewal and Termination) hereof. Nextel shall also be permitted to withhold any "Computable Amounts" from any invoice. (e) The failure of Nextel to pay a disputed invoice or to pay the disputed part of any invoice shall not constitute a breach or Default by Nextel provided that the procedure described above herein has been followed with respect to the matter. In the event that Nextel disputes an amount invoiced by Amdocs and the procedure described in clause (d) above results in a determination that such amount is due and owing by Nextel, such amount shall be due and payable within [**] of Nextel's receipt of such determination. The failure of Nextel to withhold payment shall not waive any other rights Nextel may have with respect to disputed amounts or overpayments. (f) All payments under this Agreement shall be made in currency of the United States of America. (g) Notwithstanding anything above to the contrary, with regard to the Milestone related payments specified in Schedule D (Charges) hereof, Amdocs shall issue to Nextel invoices at least [**] before the anticipated Milestone achievement date. Subject to Nextel's reasonable determination that the applicable Milestone has been achieved in accordance with Schedule D (Charges), Nextel shall pay such invoices on the Milestone achievement date, which is considered to be the Due Date for the purposes of this paragraph (g); and if not paid by Nextel on such Due Date, Interest shall apply as of such Due Date without any grace period. 4.2.7 THIRD PARTY SERVICES Nextel may engage Third Parties to provide services in connection with the Customized Product; provided that Nextel shall provide Amdocs with notice prior to NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 23 -

Amdocs shall be responsible for any present or future sales, transaction, or withholding, tax imposed by a taxing authority located outside the United States for goods and/or services provided by Amdocs pursuant to this Agreement. If Nextel wishes to claim an exemption from any applicable tax, Nextel shall be required to furnish Amdocs with an exemption certificate documenting such exemption. For the avoidance of doubt, neither Party shall be responsible for the payment of any taxes, regardless of the location of the taxing authority, imposed on the income or personal property of the other Party.

(d) The Parties agree to cooperate with each other to enable each to more accurately determine its own tax liability and to minimize such liability to the extent legally permissible.

Agreement, provided however, that the Monthly Subscriber Fee shall be adjusted, effective as of the beginning of such Renewal Period, upward or downward, as the case may be, by an amount equal to the product of the Second Rate Adjustment Index and the Monthly Subscriber Fee as in effect on the date of expiration of the Initial Term; provided, further, however, that Nextel shall have the right to revoke its election to extend the Initial Term at any time prior to signing an extension for the Renewal Period. 5.2 TERMINATION FOR CONVENIENCE; CHANGE IN CONTROL OF AMDOCS; TERMINATION FOR FORCE MAJEURE; FOR FAILURE TO DELIVER ACCEPTABLE DFS 5.2.1 FOR CONVENIENCE Nextel shall have the right to terminate for its convenience the Services effective at 11:59 p.m. on the last day of any calendar quarter (e.g., March 31, etc.) (the "Termination Date" with regard to termination for convenience) by delivering to Amdocs a written "Termination Notice" at least [**] before the Termination Date. In the event Nextel terminates the Services for its convenience (in addition to paying all fees otherwise payable by Nextel hereunder through the Termination Date), Nextel shall pay to Amdocs an Exit Fee determined in accordance with Schedule I (Exit Fee Computation); provided that the amount of such Exit Fee shall be determined on the basis of the date of the Termination Notice; and provided, further, that such Exit Fee shall be payable to Amdocs in the following manner: [**] of the Exit Fee shall be payable to Amdocs on the date of the Termination Notice, [**] of the Exit Fee shall be payable to Amdocs on the Termination Date and [**] of the Exit Fee shall be payable to Amdocs on the Expiration Date (as defined in Section 5.5.1 (Disentanglement Process)), provided that this final installment of the Exit Fee shall be deposited by Nextel in a Third-Party escrow account on or prior to the Termination Date and released on the Expiration Date. For the avoidance of doubt, Nextel shall not be able to partially terminate the Services pursuant to this Section 5.2.1 (For Convenience). Notwithstanding the above, in the event that Nextel terminates this Agreement for convenience in accordance with this Section 5.2.1 (For Convenience) during the Renewal Period, Nextel shall not be obligated to pay Amdocs the Exit Fee provided that the Termination Date is fixed on a day that is at least [**] following the receipt by Amdocs of the applicable Termination Notice.

5.2.2 CHANGE IN CONTROL OF AMDOCS In the event of a Change in Control of Amdocs or Amdocs Limited that results in a Nextel Competitor or any Affiliate of a Nextel Competitor acquiring Control of Amdocs or Amdocs Limited, Nextel shall have the right to end the Term on a date that is the last day of a calendar quarter (e.g., March 31, etc.), by sending Amdocs a Termination Notice at least ninety (90) days before the Termination Date specified in such Termination Notice, provided that Nextel shall have delivered such notice to Amdocs not later than ninety (90) days following the effective date of such Change in Control. Solely for purposes of this Section 5.2.2 (Change in Control of Amdocs), Control shall mean the legal, beneficial, or equitable ownership, direct or indirect, of more than fifty percent (50%) of the aggregate of all voting or equity interests in Amdocs or Amdocs Limited, as the case may be; "Change in Control" shall mean the closing of any transaction or related series of transactions as a result of which a single person or business unit (or legally or contractually related group of persons or businesses) acquires Control of Amdocs or Amdocs Limited, as the case may be. In the event Nextel terminates the Term on the basis of a Change in Control hereunder, and provided that the Termination Date is fixed on a day that is at least [**] following the date on which the prospective Change in Control is publicly disclosed, Nextel shall not be required to pay Amdocs any Exit Fee or other termination fees. In addition, in the event of termination of this Agreement by Nextel due to Change in Control as aforesaid, Nextel shall provide Amdocs with a Termination Statement signed by Nextel in the form of Exhibit B attached hereto and Amdocs may present this statement to Third Parties and use it in any way it deems fit. The Parties agree that Nextel's provision to Amdocs of a Termination Statement hereunder shall not be construed to imply that Nextel does not believe that Amdocs has committed any Default or breach hereunder, or to prohibit or restrict Nextel's right to make any claim that Amdocs has committed any Default or breach hereunder, and notwithstanding the provision of such Termination Statement, Nextel shall have all remedies available to it in accordance with Section 9.2 (Remedies) hereof with respect to any failure or breach by Amdocs in the performance of its obligations hereunder, subject to the provisions of this Agreement, including any limitations on damages contained in this Agreement. 5.2.3 TERMINATION FOR FORCE MAJEURE EVENT If a delay or interruption of performance by Amdocs resulting from its experiencing a Force Majeure Event exceeds [**] (the "Force Majeure Period"), then Nextel may either: (i) terminate the Term, by delivering to Amdocs a Termination Notice specifying a Termination Date not less than [**] after the date of the Termination Notice; and in the event of such a termination, Amdocs shall perform its Disentanglement obligations hereunder until they are fulfilled; provided that, during the pendency of the Force Majeure Event, Amdocs shall only perform its Disentanglement obligations to the extent such obligations can be performed despite the Force Majeure Event; or (ii) engage an alternate provider (who shall be subject to the confidentiality requirements hereunder), on an interim basis, to perform the Services that Amdocs is unable to perform as a result of the Force Majeure Event until such time as Amdocs is able again to perform the Services in accordance with the terms hereof; provided, however, that if due to the Force Majeure Event, Amdocs is unable even to perform disaster recovery services under the Disaster Recovery Plan, Nextel shall have the right, beginning [**] after the occurrence of the Force Majeure Event, to terminate the Term by delivering to Amdocs a NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 27 -

Termination Notice specifying a Termination Date. Nextel [**] if Nextel terminates the Term on the basis of a Force Majeure Event. For the avoidance of doubt, the Parties expressly agree that: (i) in the event that the Force Majeure Event constitutes a "Disaster," Amdocs shall not be deemed to be failing to perform the Services if Amdocs is performing disaster recovery services in accordance with such Disaster Recovery Plan; and (ii) Nextel shall have a right to terminate the Agreement under this Section 5.2.3 (Termination for Force Majeure Event), whether or not Amdocs is so performing disaster recovery services in accordance with the Disaster Recovery Plan, in the event that due to the Force Majeure Event, Amdocs is unable to perform the Services as they would be required to be performed under this Agreement in the absence of the occurrence of the Force Majeure Event and in accordance with the CPSs (subject to any applicable Grace Period under Schedule C (Creditable Performance Specifications (CPSs)). In addition, in the event of termination for Force Majeure Event by Nextel as aforesaid, Nextel shall provide Amdocs with a Termination Statement signed by Nextel in the form of Exhibit B attached hereto and Amdocs may present this statement to Third Parties and use it in any way it deems fit. The Parties agree that Nextel's provision to Amdocs of a Termination Statement hereunder shall not be construed to imply that Nextel does not believe that Amdocs has committed any Default or breach hereunder (independent of the failure that is caused by the Force Majeure Event), or to prohibit or restrict Nextel's right to make any claim that Amdocs has committed any Default or breach hereunder (independent of the failure that is caused by the Force Majeure Event), and notwithstanding the provision of such Termination Statement, Nextel shall have all remedies available to it in accordance with Section 9.2 (Remedies) hereof with respect to any failure or breach by Amdocs in the performance of its obligations hereunder, subject to the provisions of this Agreement, including any limitations on damages contained in this Agreement. 5.2.4 EFFECT OF TERMINATION For the avoidance of doubt, any termination under this Section 5.2 (Termination for Convenience; Change in Control of Amdocs; Termination for Force Majeure) shall be effective with regard to Nextel [**] receiving Services under this Agreement, but shall not be effective with regard to [**] that has entered into its own agreement with Amdocs. 5.3 TERMINATION FOR CAUSE 5.3.1 CRITICAL DEFAULTS Section 3.7 (Dispute Resolution) hereof notwithstanding, the Term may be ended by either Party at any time, by delivering a Termination Notice specifying a Termination Date to the other Party if the other Party commits a Critical Default, provided that such Termination Date stated in any Termination Notice issued pursuant to this Section 5.3.1 (Critical Defaults)) shall be [**] or more subsequent to the date of such Termination Notice. Termination shall be effective at 11:59 p.m. on the Termination Date; in the event of such a termination by Nextel, Amdocs shall perform its Disentanglement obligations hereunder until they are fulfilled. Termination shall not constitute a Party's exclusive remedy for such a Critical Default, and such Party shall not be deemed to have waived any of its rights accruing hereunder prior to such Critical Default. Nextel shall not be required to pay Amdocs any Exit Fee or other NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 28 -

termination fees if Nextel terminates the Term for Critical Default. If Nextel ends the Term as a result of a claimed Critical Default by Amdocs and it is determined by the Arbitrator that no Critical Default was committed, then the termination shall be deemed a termination for convenience, pursuant to Section 5.2.1 (For Convenience), and Amdocs shall have all remedies available to it, in accordance with Section 9.2 (Remedies) hereof, in connection with such determination that no Default was committed. For purposes of this Section 5.3 (Termination for Cause), a "Critical Default" of Amdocs shall mean each of the defaults described in clauses (a), (d), (e) and (g) of Section 11.1.39 (Default) hereunder only; and a "Critical Default" of Nextel shall mean the default described in clause (f) of Section 11.1.39 (Default) hereunder, i.e., Nextel's failure to pay Amdocs in accordance with the provisions of this Agreement more than [**] percent ([**]%) of Amdocs' charges relating to a period of sixty (60) days or more hereunder; provided that (x) such charges are at least ninety (90) days past due; (y) Amdocs has advised Nextel's Program Manager in writing of Nextel's failure to make timely payment of such amounts and that Amdocs reserves the right to terminate or suspend the Services in accordance with the Agreement if such amounts are not fully paid within forty-five (45) days of Amdocs' above written notice, and (z) Nextel has not paid such amounts in full by the later of the ninety (90) day period specified in (x) above or the forty-five (45) day period specified in (y) above; and provided further, however, that, notwithstanding anything to the contrary provided above, there shall not be deemed to have occurred a "Critical Default" of Nextel hereunder in the event that Nextel has failed to pay Amdocs, in accordance with this Agreement, any portion (i.e., up to [**] percent ([**]%)) of Amdocs' charges relating to such period of sixty (60) days or more, if with respect to any amount greater than [**] percent ([**]%) of Amdocs' charges relating to such period of sixty (60) days or more, Nextel's Chief Information Officer or Chief Operations Officer shall have determined such amount is a "disputed amount" in accordance with Section 4.2.6(d) (Payments) hereof. 5.3.2 MATERIAL DEFAULTS In the event that Nextel believes Amdocs has committed a Default described in clause (f) of Section 11.1.39 (Default) hereunder or either Party believes the other Party has committed a Default described in clause (c) of Section 11.1.39 (Default) hereunder (each referred to hereinafter as a "Material Default"), the Party asserting that such Material Default has been committed shall provide the other Party with written notice of such claim, and within [**] of the date of such notification, an Arbitrator having at least five (5) years experience in international business shall be appointed by agreement of the Parties; provided, that if the Parties are unable to agree on an Arbitrator within such period, then, no later than the tenth (10th) calendar day after the date of notification described above an Arbitrator shall be appointed by AAA. The purpose of such arbitration shall be to determine, assuming the truth of all claims of the Party asserting that such Material Default has been committed, whether the other Party's failure or breach is "material" for purposes of clause (c) or (f) of Section 11.1.39 (Default), as the case may be. The arbitration (as well as any subsequent arbitration provided below) shall be conducted (i) under the rules of the AAA; (ii) in New York City; and (iii) in the English language. Within [**] of the date of the original notification described above, the Arbitrator shall make its initial determination of materiality, and if the Arbitrator confirms that the asserted failure or breach is "material," then within [**] of the original notification described above, the Arbitrator must determine whether the asserted Material Default was in fact committed and was NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 29 -

not cured within the applicable cure period therefor, if any (i.e., that the conditions of a Default under clause (f) or clause (c), as the case may be, of Section 11.1.39 (Default) were met). If the Arbitrator determines that a Party did in fact commit a Material Default, or the Arbitrator fails to render a determination within [**] of the original notification as to whether such Material Default was in fact committed, then the Party asserting such Material Default shall have the right to terminate this Agreement. The [**] time limit during which the Arbitrator must determine whether a Party has in fact committed a Material Default shall be reduced by the number of days in excess of thirty (30) elapsing between the date of the original notice described above and the date of the Arbitrator's initial threshold determination of materiality. In the event that the Arbitrator rules that a Material Default has been committed by a Party, the other Party may initiate the termination by sending the other Party a Termination Notice specifying a Termination Date, provided that such Termination Date shall be [**] or more subsequent to the date of such Termination Notice. Termination shall be effective at 11:59 p.m. on the Termination Date, and, in the event of such a termination, Amdocs shall perform its Disentanglement obligations hereunder until they are fulfilled. Upon termination by Nextel pursuant to this Section 5.3.2 (Material Defaults), Amdocs shall [**] subsequent to the expiration of any cure period contained in clause (c) or clause (f), as the case may be, of Section 11.1.39 (Default). Termination shall not constitute a Party's exclusive remedy for a Material Default of the other Party, and the Arbitrator shall have time beyond the [**]time period referenced above to determine the damages due to a Party for such asserted failure or breach of the other Party hereunder. Further, a Party shall not be deemed to have waived any of its rights accruing hereunder prior to submitting the original notice described above, and Nextel shall not be required to pay Amdocs any Exit Fee or other termination fees if Nextel terminates the Term pursuant to this Section 5.3.2 (Material Defaults). Further, the non-prevailing Party in any arbitration conducted pursuant to this Section 5.3.2 (Material Defaults) shall be required to pay the arbitration costs, including reasonable attorney's fees, of the other Party. If a Party asserting a Material Default terminates this Agreement, in accordance herewith, on the basis of the Arbitrator's failure to render a determination within [**] of the original notification, as to whether such Material Default was in fact committed, the arbitration shall continue in order to determine whether such Material Default was committed; and if such determination is that neither a Critical Default or a Material Default was committed, then the termination shall be deemed a termination for convenience, pursuant to Section 5.2.1 (For Convenience). 5.3.3 OTHER DEFAULTS In the event that either Party (the "First Party") commits an Other Default, the other Party (the "Second Party") may, after providing the First Party with written notice of such Other Default, submit the matter to the escalation procedures set forth in Section 3.7 (Dispute Resolution). If, as a result of such procedure, the Arbitrator determines that the First Party did in fact commit an Other Default, then the Second Party shall have the right to terminate this Agreement by sending the First Party a Termination Notice specifying a Termination Date, provided that such Termination Date shall be [**] or more subsequent to the date of such Termination Notice. Termination shall be effective at 11:59 p.m. on the Termination Date; in the event of such a termination by Nextel, [**]. Termination shall not constitute the Second Party's exclusive remedy for such an Other Default, and the Second Party shall not be deemed to have waived any of its rights accruing hereunder prior to such Other NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 30 -

Default. Nextel shall [**]. For purposes of this Section 5.3 (Termination for Cause), an "Other Default" of Amdocs shall mean the Default described in clause (b) of Section 11.1.39 (Default) hereunder and an "Other Default" of Nextel shall mean the Default described in clause (e) of Section 11.1.39 (Default) hereunder. 5.4 EXTENSION OF SERVICES In the event that the Agreement has been terminated by Nextel in accordance with the terms hereof, or in the event that the Initial Term (or the Term, in case of Renewal) has expired, Nextel may, at its sole option and discretion prior to the applicable Termination Date, extend the effective date of any such expiration or termination of the Term for up to [**] successive periods of up to [**] each beyond the applicable Termination Date, upon at least [**] prior, written notice to Amdocs. The Parties hereby acknowledge, for the avoidance of doubt, that during any period of extension under this Section 5.4 (Extension of Services) all terms and conditions of this Agreement shall continue to apply, including but not limited to: (i) the Monthly Subscriber Fee and Maintenance Fee and (ii) the CPSs and the imposition of Performance Credits for Amdocs' failure to meet such CPSs, and the application of bonuses with respect thereto. 5.5 TRANSFER ASSISTANCE (DISENTANGLEMENT) 5.5.1 DISENTANGLEMENT PROCESS The Disentanglement process shall begin on the earlier of the following dates: (i) the ninetieth (90th) day prior to the end of the Initial Term or of the Renewal Period, as the case may be; or (ii) the date a Termination Notice is delivered by Nextel. During the Disentanglement process, Amdocs shall perform certain services related to the transition of any terminated Services to Nextel or Nextel's designee as described herein below (the "Disentanglement Services"), including but not limited to, after the Termination Date, certain continuation of the Services or any component thereof (the "Continuation Services"). Amdocs' obligation to perform the Services, and Nextel's obligation to pay for the Services in accordance with the terms set forth in this Agreement and, for the avoidance of doubt, other than for the Disentanglement Services including the Continuation Services, shall expire: (A) at the end of the Initial Term or of the Renewal Period, as the case may be; or (B) on the applicable Termination Date specified pursuant to Section 5 (Term, Renewal and Termination); provided, however, that Nextel's obligation to pay for Services rendered prior to such date, but not yet paid for in accordance with the terms hereof, shall remain in effect subsequent to such date. After the Termination Date, Amdocs shall provide the Disentanglement Services, including the Continuation Services, as and to the extent reasonably requested by Nextel, for up to six (6) months after the Termination Date (the "Initial Disentanglement Period"), including any extensions thereof under Section 5.4 (Extension of Services) hereof (with the date on which Amdocs' obligation to provide Disentanglement Services expires being referred to herein as the "Expiration Date"); provided, however, that, upon ninety (90) days' prior written notice, Nextel may extend such Expiration Date by an additional six (6) month period (the "Additional Disentanglement Period"). Following the Termination Date (i.e., during the Initial Disentanglement Period and the Additional Disentanglement Period, if any), the CPSs shall remain in effect; provided, however, that Amdocs shall not be subject to the application of any NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 31 -

Performance Credits, or entitled to earn any Bonuses (as such term is defined in Schedule C (Creditable Performance Specifications (CPSs))), during either the Initial Disentanglement Period or any Additional Disentanglement Period. Amdocs and Nextel shall discuss in good faith a plan for determining the nature and extent of Nextel's Disentanglement obligations and for the transfer of Services in process, provided, however, that Amdocs' obligations under this Agreement to provide all Disentanglement Services reasonably requested by Nextel shall not be lessened, to the extent practicable. Except as otherwise explicitly provided in the Agreement, all terms and conditions of the Agreement shall continue to apply during the Initial Disentanglement Period and the Additional Disentanglement Period, if any. 5.5.2 GENERAL OBLIGATIONS Amdocs shall take all actions reasonably necessary to accomplish, on the Termination Date, a complete transition of responsibility for the Services being terminated from Amdocs to Nextel, or to any replacement provider designated by Nextel, including the performance by Amdocs of all of the obligations imposed upon it pursuant to this Section 5.5 (Transfer Assistance (Disentanglement)), with no material interruption of or adverse impact on the Services or any other services provided by Third Parties (collectively, a "Disentanglement"). Prior to the Termination Date, Amdocs shall use commercially reasonable efforts to cooperate with Nextel and any new service provider and to perform the Disentanglement Services requested by Nextel and otherwise promptly take all steps required to assist Nextel in effecting a complete Disentanglement. Amdocs shall perform the Disentanglement Services in accordance with the manner in which it provides similar services to its similarly sized customers. Nextel shall act reasonably in assisting Amdocs in Amdocs' fulfilling its Disentanglement obligations as quickly as reasonably practicable, under the circumstances. Amdocs shall provide all information regarding the Services or as otherwise needed for Disentanglement. Amdocs shall provide for the prompt and orderly conclusion of all work, as Nextel may reasonably direct, including completion or partial completion of some projects, documentation of work in process, and other measures to ensure an orderly transition to Nextel or Nextel's designee, and Amdocs shall perform the Services in accordance with the CPSs until the Termination Date. Upon Nextel's reasonable determination that Amdocs has successfully performed all of Amdocs' obligations in connection with Disentanglement as provided in this Section 5.5 (Transfer Assistance (Disentanglement)), Nextel shall promptly provide Amdocs with written notice that a Disentanglement satisfactory to Nextel has occurred ("Disentanglement Notice"). If Nextel refuses to issue the Disentanglement Notice based on its determination that Amdocs has not yet completed its Disentanglement obligations provided in this Section 5.5 (Transfer Assistance (Disentanglement)), and Amdocs disagrees with such determination, Amdocs may submit the matter to the escalation procedures set forth in Section 3.7 (Dispute Resolution). Irrespective of the passing of the anticipated Termination Date, Amdocs' obligation to perform the Disentanglement shall not cease until the Expiration Date. 5.5.3 SPECIFIC OBLIGATIONS The Disentanglement shall include the performance of the following specific obligations: NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 32 -

(a) After delivery of the Termination Notice, the Parties shall cooperate fully with one another to facilitate a smooth transition of the Services from Amdocs to Nextel or Nextel's designated replacement provider. Such cooperation shall include the provision (both before and after the Termination Date) by Amdocs to Nextel of sufficient information available to Amdocs (including all information then being utilized by Amdocs) to enable Nextel's personnel (or that of Third Parties) who are reasonably skilled in the provision of services similar to the Services, to fully assume and continue the provision of the Services. (b) Amdocs shall use commercially reasonable efforts to convey or assign to Nextel (or its designee), any leases, licenses, and other agreements (except facility and financing leases), to the extent permissible under such agreements, that are requested by Nextel and are held by Amdocs (or cause to be conveyed or assigned any of the same held by any Affiliate of Amdocs) and used by Amdocs, Nextel, or any Subcontractor in connection with the provision or receipt of the Services (the "Essential Agreements"). Furthermore, whenever any Essential Agreement is extended, renewed, or renegotiated, Amdocs shall use commercially reasonable efforts to obtain the other party's consent to such conveyance or assignment. Amdocs' obligation under this subsection shall include Amdocs' using commercially reasonable efforts to perform all obligations under the Essential Agreements that are to be performed by it with respect to periods prior to the date of conveyance or assignment to Nextel (or its designee). Nextel shall reimburse Amdocs for expenses incurred by Amdocs in respect of Amdocs' conveyance or assignment to Nextel of any Essential Agreement or in Amdocs' obtaining the other party's consent to the assignment or conveyance of any Essential Agreement, provided Amdocs has used commercially reasonable efforts to minimize such expense. (c) Amdocs shall use commercially reasonable efforts, to the extent permissible under any contracts associated with such assets, to convey to Nextel from among those other assets then held by Amdocs for the provision of Services to Nextel, such assets as Nextel may select, at a price consisting of the fair-market value. Assets held by Amdocs shall be deemed to include assets in which title is in Amdocs' Affiliates or designees or in Third Parties pursuant to a financing lease or other security arrangements under the Uniform Commercial Code or its equivalent in non-United States jurisdictions. (d) Amdocs shall deliver to Nextel or Nextel's designee, at Nextel's request, all documentation and data related to Nextel, including the Nextel Data, held by Amdocs, except for documents and data that are legally privileged in the hands of Amdocs, and Amdocs shall destroy all copies thereof not turned over to Nextel, [**]; provided, however, Amdocs may retain archival copies of such documentation and data, solely for its internal records, subject to Amdocs' maintaining the confidentiality of any Nextel Data embedded in such archival copies in accordance with Section 6 (Confidential Information) hereof. (e) Amdocs shall reasonably cooperate with Nextel and all of Nextel's other service providers to ensure a reasonably smooth transition at the time of Disentanglement, with minimal interruption of Services, minimal adverse impact on the provision of Services or Nextel's activities and minimal interruption of any Services provided by Third Parties. NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 33 -

(f) Irrespective of the passing of the Termination Date, Amdocs shall continue to perform, until their respective completion (or until Nextel earlier directs Amdocs to cease performing), any Services relating to a subsequent Release Amdocs is performing as of the Termination Date, in accordance with the established schedule for such Release and at the Amdocs Rate. Amdocs shall use commercially reasonable efforts to complete any and all such Releases as soon after the Termination Date as possible. For a period of [**] following the completion of any Release, Amdocs shall provide Services to Nextel to facilitate the transition of such Release from Amdocs to Nextel or Nextel's designee. 5.5.4 PREPARATION FOR DISENTANGLEMENT (a) Up-to-date Documentation Amdocs shall provide to Nextel as part of the Disentanglement Services (unless otherwise required under other provisions of this Agreement), Documentation and other information for all software (including any applications developed as part of the Services) and hardware, including, but not limited to, the Amdocs Standard Materials, to enable a reasonably competent person fully to assume the provision of the Services. Amdocs shall also provide such Documentation for all upgrades or replacement software or hardware concurrently with the installation thereof. If the Documentation relates to Third-Party Standard Materials, Amdocs shall provide Nextel the Documentation then-currently made available by the provider of the Third-Party Standard Materials. If the Documentation relates to proprietary Amdocs Standard Materials, Amdocs shall provide the then-available Documentation; if such then-available Documentation is insufficient to allow persons who meet the standards required of Amdocs personnel in this Agreement to understand and operate such proprietary Amdocs Standard Materials, then Amdocs shall create sufficient additional Documentation in a timely manner and provide it to Nextel at Nextel's expense, provided Amdocs has used commercially reasonable efforts to minimize such expense. (b) Maintenance of Assets Amdocs shall procure all of its hardware, software, systems, networks, technologies, and other assets utilized in providing Services to Nextel (including leased and licensed assets) on commercially reasonable terms and shall maintain such assets in good condition and in such locations and configurations as to be readily identifiable, and to the extent practicable and permissible under any agreements associated with such assets, transferable to Nextel or its designees in accordance with the provisions of this Agreement; in addition, Amdocs shall insure such assets in accordance with the requirements of Section 8.7 (Insurance). 5.5.5 CHARGES FOR DISENTANGLEMENT SERVICES For all Disentanglement Services provided to Nextel, Amdocs shall charge Nextel and Nextel shall pay Amdocs (i) during the Initial Disentanglement Period, the Maintenance Fee and the Monthly Subscriber Fee as provided in Schedule D (Charges); provided, however, that in lieu of any minimum Subscriber Fee stated therein, a minimum Subscriber Fee of [**] Dollars ($[**]) shall apply; and (ii) during the Additional Disentanglement Period, the Maintenance Fee and the Monthly Subscriber Fee; provided, NEXTEL FINANCE COMPANY SEPTEMBER 26, 2000 CUSTOMER CARE AND BILLING SERVICES AGREEMENT CONFIDENTIAL BOSTON 2293071v3 - 34 -

however, that (w) in lieu of any minimum Subscriber Fee provided in Schedule D (Charges), a minimum Subscriber Fee of [**] Dollars ($[**]) shall be applicable with respect to up to [**] Subscribers; and (x) the Maintenance Fee and the Amdocs Rate shall each be increased by a premium of [**] percent ([**]%), and with respect to any Subscribers in excess of [**] Subscribers, the Monthly Charge per Subscriber (as defined in Schedule D (Charges) hereof) shall be increased by a premium of [**] percent ([**]%) (with such initial [**] Subscribers, however, being counted for purposes of determining the per Subscriber tiers), and any other fees under the Agreement shall be increased by a premium of [**] percent ([**]%). Nextel shall be permitted to hold back [**] percent ([**]%) of the amounts invoiced by Amdocs for Disentanglement Services until Nextel issues the Disentanglement Notice; provided that any such held back amounts shall be deposited in a Third-Party escrow account and released upon issuance of the Disentanglement Notice. Amdocs shall be entitled to a bonus in the amount of the lesser of (y) all amounts withheld by Nextel pursuant to the preceding sentence and (z) [**] Dollars ($[**]) (the "Disentanglement Bonus") upon successful completion of all Disentanglement Services. Nextel shall pay Amdocs such Disentanglement Bonus upon the issuance of the Disentanglement Notice. 6. CONFIDENTIAL INFORMATION 6.1 GENERALLY (a) To the extent that either Party (the "Discloser") discloses Confidential Information to the other (the "Recipient") the Recipient shall protect the Confidential Information of the Discloser; (b) The Recipient shall: (i) use the same care and discretion to avoid disclosure, publication, or dissemination of the Discloser's Confidential Information as the Recipient uses with its own similar information that it does not wish to disclose, publish, or disseminate; (ii) use the Discloser's Confidential Information solely for the purpose for which it was disclosed or otherwise for the benefit of the Discloser; (iii) take steps to minimize the dissemination or copying of the Discloser's Confidential Information except to the extent necessary to perform its obligations under this Agreement; (iv) not acquire any express or implied right or license under any patent, copyright, trade secret, or other right or assert any lien against Confidential Information of the other Party; and (v) use its best efforts to inform its employees, agents, and subcontractors who perform duties with respect to this Agreement about these restrictions.

SCHEDULE A PROJECT PLAN [TO BE PROVIDED]

SCHEDULE B Roles and Responsibilities Matrices Attached are the Interim Roles and Responsibilities Matrix and the On-going Roles and Responsibilities Matrix (collectively, the "Roles and Responsibilities Matrices"). Capitalized terms not defined in Roles and Responsibilities Matrices shall have the meanings set forth in the Agreement. The Interim Roles and Responsibilities Matrix will apply to the time period until first roll-out, and for all activities associated with the continued roll-out of additional markets, but does not apply to the on-going maintenance of each market, once converted. The Ongoing Roles and Responsibilities Matrix will apply to activities associated with on-going maintenance of each market, once converted.]. The level of each Party's responsibility with respect to each of the obligations set forth in the Roles and Responsibilities Matrices is specified by the insertion of the letter "O", "P" or "V" adjacent to such obligation and beneath such Party's name. The letter "O" indicates that a Party "owns" overall and ultimate accountability for completion of a task. The letter "P" indicates that a Party has a "Participation" role with respect to a task, and that a Party designated "O" may require such Party to provide certain resources or perform tasks that may be necessary for the overall task to be completed, in an amount that is commercially reasonable, under the circumstances. Both parties will communicate in an on-going fashion when the "P" is a necessity. The letter "V" indicates that a Party has "visibility" with respect to a task, and that such Party has the right , but not the obligation, to contribute, provide resources or review the process for completion of a task. The absence of any letter indicates that a Party shall have no right to have an input or any obligation with respect to a task.

SCHEDULE C CREDITABLE PERFORMANCE SPECIFICATIONS (CPS) I. SCOPE Amdocs will measure and report its performance on the 16 Creditable Performance Specifications ("CPS") set forth below, and each CPS is ranked "High," "Medium" or "Low" based on the level of criticality to Nextel (the "Criticality Levels"): CRITICAL PERFORMANCE SECTION CATEGORY NUMBER SPECIFICATION RANKING REFERENCE - --------------- ------ -------------------- ------- --------- Appendix I 1.

Each CPS shall be measured using a "Blue-Green-Yellow-Red" traffic light mechanism (the "Individual CPS BGYR State"), with "Blue" representing the highest level of performance and "Red" representing the lowest level of performance. Depending on the specific Individual CPS BGYR State, [**] Also, on a monthly basis, an overall CPS score (the "Overall CPS Score") will be determined, by assigning points to each CPS based on its Individual CPS BGYR State and its Criticality Level (with a higher Overall CPS Score indicative of a lower level of performance by Amdocs). The matrix set forth below describes the methodology for computing the Overall CPS Score: Privileged and Confidential -33-

Criticality Level ----------------------------------------- Individual CPS BGYR State High Medium Low - ------------------------- ---- ------ ---- Blue [**] [**] [**] Green [**] [**] [**] Yellow [**] [**] [**] Red [**] [**] [**] Further, in the event that, during any Measurement Period : (i) the [**] CPS has averaged [**]% or less; (ii) the [**] CPS has averaged [**]% or less; (iii) the [**] CPS has averaged [**]% or more over [**] seconds; or (iv) any billing cycle has not been completed on or prior to the date which is [**] to its scheduled completion date, then [**]points shall be added to the Overall CPS Score. III. GRACE PERIODS The Parties have agreed that for certain specified time periods (each a "Grace Period") Amdocs' obligation to perform the Services in accordance with some or all of the CPS will be suspended (such CPS referred to hereinafter as the "Suspended CPS") upon the occurrence of certain events that the Parties recognize will negatively impact Amdocs' ability to perform the Services in accordance with the CPS ("CPS Suspension Events"). During the applicable Grace Period, (i) Amdocs shall [**][**] with respect to any Suspended CPS and (ii) no Suspended CPS [**] under Section 11.1.39 of the Agreement; provided however that during any Grace Period Amdocs shall be required to perform the services measured by such Suspended CPS in a timely, accurate and professional manner. Set forth below is a table summarizing the CPS Suspension Events and the related Suspended CPS and Grace Periods: No. Suspension Event Grace Period Suspended CPS - ---- --------------------------------------------- ---------------------------- ------------- 1.

Appendix A - List of Documents....................................... 5

1. INTRODUCTION 1.1 GENERAL This document outlines the documentation framework for Nextel set of documentation. 1.2 PURPOSE OF THIS FRAMEWORK The purpose of the documentation framework is to: - Provide a list of existing and future documents that have been/will be provided to describe Nextel's system, implementation, and conversion efforts. - Reflect the current status of the project documentation. - Outline general standards for writing project documentation within the Nextel set. - Serve as a guide for team members when allocating numbers for new documents within the overall project documentation framework established. The document groups and books are often set up in accordance with projected software modules and processes and do not always reflect the actual features implemented and/or documented. 1.3 PRINCIPLES OF DOCUMENT SET ORGANIZATION Documentation for a project is divided hierarchically into the following subdivisions: - A set includes all the documents describing a complete system. The set is designated by the first two characters of the document catalogue number. - The set is divided into groups, with each major documentation topic covered by a different group. For example, a set might include a group on data entities, another for functional descriptions, another for technical descriptions, and so on. The third character of the catalogue number of the document specifies the group. - The group is further subdivided into books. There is normally one book for each subdivision of the application. For example, in the group for functional descriptions, there might be a book for each application within the system. In the data group, there might be separate books for database, tables, indexes. The next two numbers of the catalogue number of the document specify the book. - The last two digits of the catalogue number specify the document within the book. There might be several documents within a book. For example, in the table book of the data group, there might be a separate document describing each table.

Each document constitutes an independent entity and is identified by the document name. In addition, a unique number is allocated which serves as the key in the main document table. This number is in the SSGBBDD format, in which: - SS is the set name - G is the group number; - BB is a two digit book number; - DD is a two digit document number. For example, this document is catalogued as XX10101; that is, it belongs to the Nextel set, which describes the Nextel/BSO project. It is in group 1 of that set, the general group. It belongs to book one of the group, which is documentation. It is the first document of the book, the document framework for the set and for the BSO project. 1.4 TYPES OF DOCUMENTS Documentation describing the various applications related to BSO can be divided into the following types of documents: - FUNCTIONAL SPECIFICATIONS The functional specifications document contains a complete description of the functionality provided by the subsystem or application described. Special logic, considerations, , information handling processes, must be included in the document. The specification does not, however, describe how this functionality is to be implemented.

In the event Nextel's number of Subscribers exceeds [**], then the above additional fixed amount will be increased by $[**] per each Subscriber above [**]. For the avoidance of doubt, the $[**] per Subscriber above [**] is an annual charge (and not a monthly charge).

Nextel shall have the right, at its sole discretion, exercisable by a written notice to Amdocs delivered at least [**] prior to the expiration of the above initial [**] year term, to extend the initial term arrangement for a period of [**]] year. At the end of this [**] year extension period, Nextel shall have the right to extend the term of the arrangement until [**], by a written notice to Amdocs delivered at least [**]) days prior to the expiration of the [**] extension period. Following the above [**] year period and its extensions as aforesaid, if any, the following shall apply:" 4.

AMENDMENT NO. 4 DATED AS OF DECEMBER 16, 2002 ("AMENDMENT EFFECTIVE DATE") TO THE CUSTOMER CARE AND BILLING SERVICES AGREEMENT DATED AS OF JANUARY 1, 2000 BETWEEN NEXTEL FINANCE COMPANY ("NEXTEL") AND AMDOCS SOFTWARE SYSTEMS LIMITED ("AMDOCS") Nextel and Amdocs have executed and are currently performing the Customer Care and Billing Services Agreement dated as of January 1st, 2000, as amended by Amendment No. 1 dated March 15, 2001, Amendment No. 2 dated April 15, 2002, and Amendment No. 3 dated December 6, 2002 (the "CCBS Agreement"). The parties desire to amend and modify Schedule D (Charges) of the CCBS Agreement as described herein. Nextel and Amdocs have agreed to clarify their understanding of the Subscriber count process for the purpose of calculating the Monthly Subscriber Fee ("MSF"). Accordingly, the parties have agreed to execute this Amendment No. 4 to the CCBS Agreement (the "Amendment") to reflect the required changes in Schedule D of the CCBS Agreement as of the Amendment Effective Date. 1. The CCBS Agreement shall hereby be amended by adding the following as Section 7A at the end of Section 7 of Schedule D: DEFINITIONS For the purpose of calculating the MSF, the definitions listed below in this Section 7 shall have the meaning ascribed to them in this Section 7. Unless otherwise defined in this section all terms shall have the definition as set forth in the Agreement. ALS (Alternate Line Service) - ALS is a service offered by Nextel that allows for additional PTNs to be added to a single SIM. [**]. BAN (Billing Account Number) - BAN is the Nextel account number under which a single or multiple Subscribers are invoiced by the Customized Product for Nextel services. IMEI (International Mobile Equipment Identity) - The unique identifying number for each wireless telecommunications device. LOAD BALANCING - A change in billing cycles approved by Nextel and Amdocs for specific BANs in order to improve the Customized Products processing efficiency or to satisfy Nextel's business initiatives (e.g., consolidate corporate accounts). Cycle changes requested by a Nextel customer for the convenience of such customer (e.g. change of cycle billing date) are not considered to be Load Balancing. MULTI-NAM (Number Assignment Module) - Multi-NAM is a service offered by Nextel that allows a customer to have different PTNs in different markets on the same

wireless telecommunications device (e.g., a different PTN in Chicago and New York), which results in an IMEI for each PTN. Each such IMEI/PTN combination under the Multi-NAM service shall be considered a separate Subscriber. PTN - Personal Telephone Number SIM (Subscriber Identification Module) - Identifies each subscriber to the Nextel Network. Calculation of the MSF. (a) Amdocs shall invoice Nextel in the MSF for cancelled Subscribers up to but not exceeding [**] from the date of cancellation. If, after the [**], there is new billing activity (e.g. credits, payments) for the Subscriber, Amdocs shall invoice Nextel for the MSF for the month in which the new billing activity occurs. Annex C to this Schedule D provides an example of the application of the above provision. For the purpose of calculating the MSF, a Subscriber shall be considered as cancelled upon setting the field "STATUS_CODE" in the "BILL_SUBSCRIBER" table of the Customized Products to a value of "C". (b) As the Customized Product invoices cancelled Subscribers for up to [**] beyond their cancellation date, and in order to comply with the provisions of sub-paragraph (a) above, Nextel and Amdocs shall modify the following Customized Product reference tables to be capped in the aggregate at [**] unless agree between the parties otherwise i. MARKET_SERVICES table (GUID_EXTENTION_PRD field) ii. MARKET_POLICY table (DAYS_LIMIT_FOR_USG_PROC field) (c) In addition, in order to comply with the provisions of paragraph (a) above, the number of days in the Customized Product logic for the accommodation of late charges and adjustments will be set to [**], but only for the purpose of the above compliance. In the event that Subscribers are moved to an alternative bill cycle as a result of Load Balancing, Amdocs shall invoice Nextel for those Subscribers only once in any given month. (d) If, at the expiration of the [**] period after cancellation for a given cancelled Subscriber, the BAN containing that Subscriber has no active Subscribers but still has an outstanding balance due or a credit, and that balance or credit is not in a "Written-Off" status in the Customized Products, then for the purpose of such invoicing, Amdocs will consider this BAN as having a single Subscriber until such time as the balance or credit is "Written-Off", or the balance becomes zero as a result of a payment being applied or a credit balance being refunded. Amdocs will not invoice Nextel for BANs marked as "Written-Off" or "cancelled with zero balance", and is entitled to close and archive these BANs from the Customized Products after [**] from the "Write-Off" or cancellation date.

(e) Nextel and Amdocs have agreed that, as a result of implementing the principles of calculation of the MSF described in this Section 7, Amdocs shall provide Nextel with a one-time credit in the amount of $[**] in the December 2002 invoice for MSF. 2.
