               referenced "Motorola Quotation", defined below in Section 2.4.1.
               For these purposes, the following statement on a Purchase Order
               document shall suffice as such incorporation by reference and
               supersession:

                      "All terms and conditions of the Nextel International,
                      Inc./ [See schedule Item 1 ]/ Motorola, Inc. iDEN(R)
                      Infrastructure Equipment Supply Agreement, dated as of
                      June 30, 2000, as amended, shall apply to this purchase
                      order and shall supersede and replace any preprinted or
                      other terms and conditions contained herein."


               Standard Equipment order lead times and installation period shall
               be as set forth in the Price Book, as modified by Motorola from
               time to time. If a Purchase Order makes reference to a valid
               Motorola Quotation, such Motorola Quotation shall become
               incorporated into such Purchase Order when the latter becomes
               effective. At Customer's request, Motorola shall use commercially
               reasonable efforts to reduce lead times. If shortening any such
               lead time requires an extra fee, Motorola shall provide Customer
               such option.

        2.4.1  Additional Definitions:

               (a)Authorized Signatory. For the purposes of Section 2.4, an
                  "Authorized Signatory" is a person authorized by Customer or
                  by Motorola to execute or acknowledge Purchase Orders, Project
                  Agreements, Motorola Quotations, or amendments thereto. Each
                  party shall provide the other written notice of its respective
                  Authorized Signatories and changes to same.

               (b)Purchase Orders. A "Purchase Order" is a purchase order on a
                  form provided either by Customer or by Motorola, provided that
                  such form contains the preceding requirements for
                  incorporation by reference and supersession. A Purchase Order
                  may be either associated with a "Project Agreement", defined
                  below, or not so associated. A non-associated Purchase Order
                  will be billed [*] upon shipment, with payment due within [*]
                  of such invoice. A Purchase Order in proper form and executed
                  by Customer becomes effective upon acceptance by Motorola
                  pursuant to Motorola's order acknowledgment procedures or
                  other notification. For all Customer purchases, Motorola shall
                  provide acknowledgment to both Customer and Nextel
                  International. If Customer subsequently requests a change to
                  the scope of work required pursuant to a Purchase Order,
                  Motorola may propose additional charges and address schedule
                  impact for such changed scope of work. All Purchase Orders or
                  Change Orders shall be signed by an Authorized Signatory of
                  Customer.

               (c)Project Agreements. "Project Agreements" are defined in
                  Exhibit "A". Project Agreements shall identify all Purchase
                  Orders related to the Project Agreement. The Project Agreement
                  is not intended as a reconciliation document, nor is a Project
                  Agreement intended for the purchase of Equipment, Software,
                  and/or Services. If Customer requests changes to the scope of
                  the work required for an executed Project Agreement, Motorola
                  may propose additional charges and/or schedule revisions for
                  such changed scope of work.

               (d)Motorola Quotations. "Motorola Quotations" are quotations
                  provided by Motorola to Customer for Equipment, Software,
                  and/or Services that are not in the Price Book or require
                  customization or deviate in any way from standard product or
                  service offering detailed in the Price Book. Such quotations
                  may include related terms and conditions, including pricing.
                  All Motorola Quotations are subject to this Agreement, and any
                  terms and conditions in a Motorola Quotations inconsistent
                  with those in this Agreement are governed by those in this
                  Agreement. If after Motorola's acknowledgment, Customer makes
                  changes to the scope of the work required for the Motorola
                  Quotation, Motorola may propose additional charges and/or
                  schedule revisions. If requested by Customer, Motorola shall
                  use commercially reasonable efforts to seek reduction of lead
                  time on third party product impacting Customer's schedule.

        2.4.2  Order Process

               Purchase Orders for Price Book items may be completed by Customer
               without the need for input from Motorola. Receipt of Purchase
               Orders will be acknowledged by Motorola. Non-Price Book items
               require a Motorola Quotation.

               Project Agreements are created by Motorola using the form set out
               in Appendix I to Exhibit "A" hereto and sent to Customer for
               approval. Customer shall review all documents and indicate its
               acceptance by signing and returning an executed copy to Motorola
               or shall work with Motorola to achieve mutually acceptable
               revisions to the proposed Project Agreement, after which both
               Customer and Motorola shall execute such revised Project
               Agreement.

        2.4.3  Changes in Purchase Orders and Project Agreements

               (a)Purchase Order Modification. Any modification after such
                  Purchase Order has been accepted by Motorola other than
                  cancellation shall be made only by written mutual agreement
                  accompanied by a revised or replacement Purchase

                  Order executed by an Authorized Signatory of Customer, except
                  for the type of changes set forth below ("Purchase Order
                  Adjustments"):

                      (i)  Changes to Customer requested ship dates, not to
                           exceed [*] extension;

                      (ii) Changes to shipping locations to an alternate
                           authorized Customer location.

                  Purchase Order Adjustments may be made by the agreement of one
                  Authorized Signatory from Customer and one Authorized
                  Signatory from Motorola, provided that such agreement is
                  confirmed via contemporaneous faxed or emailed confirmations
                  exchanged between Customer and Motorola.


               (b)Purchase Order Cancellation. Customer may cancel a Purchase
                  Order without charge up to [*] after the order, provided that
                  shipment has not occurred. Unless otherwise specified in a
                  proposal, reasonable and customary cancellation fees as set
                  forth in the Price Book shall apply.

               (c)Project Agreement Modification and Cancellation. Any
                  modification or cancellation of a Project Agreement shall be
                  made only by written amendment executed by Authorized
                  Signatories from each party. After the execution of a Project
                  Agreement or amendment, any change or cancellation by Customer
                  to an associated Purchase Order requires execution by Customer
                  and Motorola of an amendment to such associated Project
                  Agreement. Should such Purchase Order change or cancellation
                  by Customer change the Project in such a way that the
                  remaining associated Purchase Orders no longer constitute a
                  System or System Expansion, as defined for the purposes of
                  Exhibit "A", then the payment terms for all such associated
                  Purchase Orders shall revert to [*] of the purchase price upon
                  shipment. Customer shall pay such invoices within [*] of
                  issuance.

3.0     OBLIGATIONS OF CUSTOMER

        Customer shall:

        3.1    Design the RF coverage plan and frequency plan for each Area
               including but not limited to Site location, frequencies at each
               Site, RF coverage from each Site, co-channel interference caused
               from one Site to another Site, co-channel interference from
               non-Customer sites.

4.0     OBLIGATIONS OF MOTOROLA

        Motorola shall:

        4.1    [Intentionally Omitted]

        4.2    Negotiate in good faith Implementation Schedules and perform
               according to such Schedules.

        4.3    Negotiate in good faith the Punchlist for the System or System
               Expansion and Expansion Product prior to the expiration of the
               [*] period following the date of each respective Conditional
               Acceptance.

        4.4    [Intentionally Omitted]

        4.5    Keep Customer advised of modifications required on a timely
               basis.

        4.6    Provide, at a reasonable cost to Customer, a retrofit package for
               any change in standards subsequently put into effect by the
               industry, the government, regulatory agencies, as well as those
               promulgated by Motorola.

        4.7    Continue to develop operability and reliability improvements to
               iDEN technology over time to reduce the Customer's cost of
               ownership on a per Subscriber basis and continue to develop and
               implement new feature functionalities agreed to by the parties
               throughout the term of the Agreement.

        4.8    When requested to by Customer, review the frequency plan prepared
               by Customer or Customer's consultant at no additional charge to
               Customer. Because of differences in radio coverage and
               interference models and the timeframe of implementation, this

6.0     PAYMENT AND PRICING

        6.1    General Payment Terms

               Customer shall pay to Motorola the price of subsystem Equipment
               and Software components and related Services, as set forth in the
               Price Book in effect at the time of such Equipment order or
               applicable Motorola Quotation, and will use an appropriate

               terms and payment schedules:

               6.1.1  The Price Book contains standard lead times (which are
                      updated as market conditions change) and expedite fees
                      which are incorporated by reference herein. Motorola does
                      not warrant that lead times can be moved in. At times
                      Motorola can move in such lead times by paying Motorola's
                      suppliers expedite fees, paying for overtime or other
                      methods. If Motorola is requested to perform in such times
                      Customer shall pay the expedite fees set forth in the
                      Price Book. The lead times set forth in the Price Book
                      will be shown for both cases where the product is
                      forecasted and when it is not forecasted.

                      [*] Customer shall pay such invoices within [*] of
                      issuance.

                      Motorola shall from time to time set credit limits for
                      Customer. The credit limits shall be communicated from
                      Motorola's iDEN controller to Customer and Nextel
                      International. Motorola reserves the right to change these
                      amounts based upon a change in credit condition. Motorola
                      shall notify Customer and Nextel International in writing
                      of any credit limit change. Customer and Nextel
                      International warrant that they will provide and update
                      all the relevant financial information needed or requested
                      by Motorola to make these credit decisions.

                      If (a) any of the credit limits are exceeded by Customer
                      or (b) if account is delinquent for Customer or any other
                      NII Affiliate doing business with Motorola, then Motorola
                      may require (after written notice and three (3) business
                      day to cure) the Additional Assurance procedures set forth
                      in Section 6.9 before any subsequent shipment to Customer.
                      Motorola may hold shipments pending the receipt of
                      Additional Assurance if there is a material adverse change
                      in the business or financial condition of Customer, any
                      other NII Affiliate doing business with Motorola, or
                      Nextel International.

                      As long as the total of all billing disputes involving
                      Customer, any other NII Affiliate doing business with
                      Motorola, or Nextel International are less than [*],
                      Motorola will not request Additional Assurance until it
                      has used its best efforts to clear up any billing disputes
                      or delinquencies.

               6.1.3  Taxes, duties and fees: Exclusive of corporate and
                      personal income taxes, all taxes applicable to this
                      transaction, including but not limited to sales, lease,
                      service rental, use, property, wage, occupation, value
                      added or similar taxes, customs and import duty, and any
                      similar provincial or local government obligations shall
                      be borne by Customer. Upon Motorola's request, Customer
                      shall produce sufficient evidence within thirty (30) days
                      of such request to prove that Customer has fulfilled its
                      obligation relating to all taxes, duties, and fees. If any
                      such taxes, duties, or fees are determined by the
                      applicable taxing authorities to be applicable to this
                      transaction and, notwithstanding Customer's
                      responsibility, Motorola is required to pay or bear the
                      burden thereof, then the prices set forth in the Price
                      Book, Project Agreement or Motorola Quotation shall be

                      no later than thirty (30) days after receipt of an
                      invoice. Motorola shall, where possible, use reasonable

                      Motorola's sole judgment, the effort and/or result would
                      be to Motorola's detriment.

                      in the Price Book or as specifically proposed by Motorola.
                      Exhibit "N" hereto sets forth alternate IPL license fees
                      that may be elected by Customer, in whole but not in part,
                      if Customer meets the qualifications set forth therein. In
                      the event there is an Alternate Infrastructure
                      Manufacturer, the parties shall agree to a new method of

                      it appears in the Price Book. All Software shall be
                      licensed per the terms and conditions set forth in Exhibit
                      "F".

                      The software [*] offered in Exhibit "N" is valid only for
                      the purchase of [*] as a package from Motorola. If any
                      Motorola [*] hardware is purchased directly from a third
                      party source, the [*] shall be charged in addition to any
                      applicable fees set forth in Exhibit "N". Motorola does
                      not accept any liability for System integration or
                      warranty obligation for such separately purchased hardware
                      or software, and if Motorola is called on any warranty
                      claim or other service request involving such hardware or
                      software, Customer [*] for such calls.

               6.1.5  Except as provided in Section 6.1.8, Customer shall pay
                      for any training ordered by the Customer per the Price
                      Book and other appropriate agreements.

               6.1.6  Subject to the conditions contained in 4.11 any costs
                      required to modify the System in order to comply with
                      local codes or regulations shall be Customer's

               shall be counted in the same manner as if Customer had made such
               purchases directly.

        6.8    Notwithstanding anything to the contrary in this Agreement, [*].

        6.9    Additional Assurance Payment Terms

                      written notice by Motorola to Customer that Motorola

                      re-stocking charges, etc. and promptly refund only that
                      portion of the advance payment amount which exceeds the
                      total of such charges.

                      The Letter of Credit shall be in the amount of [*] of the

                           after presentation of the final Acceptance

                      If Motorola is prevented from obtaining Conditional
                      Acceptance because Customer has not completed its
                      obligations hereunder (except as provided in Section 18)

        6.10   Purchase Commitment

               Nextel International commits that the NII Affiliates shall
               purchase an aggregate of at least One Hundred Fifty Million
               Dollars ($150,000,000) of FNE, Software, and Services in calendar
               year 2000. Should such commitment not be achieved, Nextel
               International agrees to pay Motorola by the end of the first
               quarter of 2001 an amount equal to [*] of the difference between
               [*] and the actual aggregate amounts of FNE, Software, and
               services shipped/provided by Motorola to the NII Affiliates in
               calendar year 2000. Any commitments and rebates for such
               aggregate purchases in the years 2001, 2002, and 2003 shall be
               the subject of subsequent agreement(s) between Nextel
               International and Motorola. Nextel International and Nextel
               Communications, Inc. shall each receive their own earned rebate
               or pay their own penalty, and there is no duplication.
               Specifically, the above specified One Hundred Fifty Million
               Dollars ($150,000,000) is part of the Nextel Communications, Inc.
               [*] commitment and is not an additional commitment.

        6.11   System Performance

               When Motorola and Nextel Communications, Inc. negotiate
               liquidated damages agreement(s) for box down time and system
               uptime for the U.S. market, this Agreement shall be amended to
               offer Customer similar agreement(s). The calculation metrics
               shall be consistent with those used in the Nextel Communications,
               Inc. agreement.

7.0     ACCEPTANCE TESTING

        7.1    Customer and Motorola agree that the acceptance testing shall be
               done for all new Systems and a modified ATP shall be performed
               for all System Expansions and shall be included in all relevant
               Purchase Orders, Project Agreements, and Motorola Quotations. The
               ATP tests shall be chosen from the GATP, as set forth in Exhibit
               "C", that Customer and Motorola have agreed to and identified on

               Project Agreement or Motorola Quotation when Customer purchases
               ATP Services.

               This ATP is generic in nature and tests operational features.
               Should a certain feature or option not be purchased then it is
               agreed that portion of the ATP shall be deleted and will not be
               performed. Motorola shall supply new sections to cover new
               products or features that Motorola develops. The GATP will be
               amended to reflect desired practices for testing Systems in
               Commercial Service. Customer and Motorola acknowledge that
               different approaches are required for Systems in Commercial
               Service and those acceptable for Systems not in Commercial
               Service.

        7.2    Should Customer request additional testing above and beyond the
               ATP, these tests shall not be considered until after Conditional
               Acceptance of the System or System Expansion. Motorola shall
               prepare and present to Customer a quotation detailing the time
               and material charges that such additional testing may require on
               a time and material basis. [*]

        7.3    Individual Site Tests and the Switch Test shall be performed in
               accordance with the ATP as soon as the individual Sites and
               Switch are completed. The System Test shall be performed as soon
               as the Switch and Site Tests are completed. If all the Sites are
               not available and operational due to Customer's failure to obtain
               the Sites by the required scheduled time as contained in the
               Implementation Schedule hereto ("Unavailable Sites"), the tests
               shall still take place.

        7.4    The Areas served by the Unavailable Sites shall not be included
               in the System Test. When the Unavailable Sites are operational
               and available, the Site Test shall be completed. The existence of
               Unavailable Sites shall not hold up the ATP or Conditional or
               Final Acceptance.

        7.5    Additional Testing Costs

               The cost of obtaining a passing test for each of the items in the
               ATP is included in the purchase price of the ATP. Any additional
               testing requested and approved by Customer shall be billed to
               Customer as set forth in Section 7.2. This includes, but is not
               limited to, testing due to:

               a. Customer's desire for testing not included in the ATP; and

               b. Re-testing that is needed because the Customer's Site team
                  makes changes to agreed schedules to such an extent Motorola
                  needs to materially extend the time period its ATP team needs
                  to complete the ATP; and

               c. RF interference from outside sources; and

               d. The need to respond to complaints of third parties alleging
                  Customer's System interferes with their systems, unless the
                  Equipment sold hereunder is defective or not operating within
                  licensed parameters; and

               e. Unavailable Sites.

8.0     FNE WARRANTY AND SOFTWARE MAINTENANCE PROGRAM

        8.1    FNE Hardware Warranty

               8.1.1  FNE is warranted to be free from defects in material and

                      will be repaired at the Motorola repair depot [*] except
                      as outlined herein.

               8.1.2  Customer shall be responsible for the initial level of
                      diagnosis (i.e., for identification and isolation of FNE
                      hardware problems to the board level), for hardware,
                      firmware and software removal and replacement, and for
                      sending the malfunctioning product, packed in a manner to
                      prevent damage, to the designated Motorola repair depot.
                      Customer shall be responsible for [*] Motorola's repair
                      depot. When such products or their replacements are being
                      returned to Customer, Motorola shall bear such charges.

               8.1.3  Parts and labor at the Motorola repair depot to repair or
                      replace defective FNE will be [*].

               8.1.4  In the event a defect occurs during the warranty period
                      Motorola, at its option, will either repair or replace the
                      product. Any item replaced will be deemed to be on an
                      exchange basis, and any item retained by Motorola through
                      replacement will become the property of Motorola. Repaired
                      or replaced parts shall have a warranty of the greater of
                      the remainder of this warranty period or [*].

                      of Exhibit "K" times the number of Subscribers in service
                      (as calculated per the procedures set forth in Exhibit
                      "K"). This Total NII SMP Price per Subscriber is based on
                      the aggregated SMP costs for all NII Affiliates divided by
                      the aggregated number of Subscribers for all NII
                      Affiliates. For calendar year 2000, Motorola quoted this
                      same Total NII SMP price per Subscriber figure to each NII
                      Affiliate. (See Section 3 of the Year 2000 SMP Proposal
                      for Customer, set forth in Exhibit "O".) In future years,
                      Motorola shall include the "Nortel Patch" shown in the
                      bottom row of Exhibit "K" in the calculations for Total
                      SMP. If in future years Nextel International elects to
                      depart from an NII Affiliate average SMP pricing
                      methodology, Motorola shall charge the actual SMP costs
                      for each market for such years. Customer shall pay SMP
                      fees on a quarterly basis. The quarterly payment shall be
                      one-quarter of the calculated annual payment. The quoted
                      prices are for the services defined in Exhibit "O". The
                      SMP Agreement shall be evidenced by Customer's Purchase
                      Order indicating which sections of said proposal are
                      agreed to by Customer and Motorola. Any additional
                      services agreed to by Customer and Motorola shall also
                      contain applicable pricing for such services.

               8.4.2  Motorola warrants that at the time of ATP or delivery of
                      Software, that the Software will cause the System to
                      operate as required by the ATP. Thereafter, all
                      reproducible software defects or bugs shall be corrected
                      as part of SMP.

               8.4.3  Motorola represents and warrants that Software supplied
                      under this Agreement does not have "Software Traps"
                      designed to permit unauthorized access, to disable or
                      erase software, hardware or data or to perform any other
                      such actions.

        8.5    Non-FNE Products

               Non-FNE products are warranted only to the extent provided to
               Motorola by the manufacturer or supplier of such product.
               Motorola shall identify in the Price Book the extent of third
               party warranties.

        8.6    Motorola warrants that each hardware, software, and firmware
               product delivered under this Agreement and listed on Exhibit "M"
               as "Year 2000 Compliant" shall be able to accurately process date
               data (including, but not limited to, calculating, comparing, and
               sequencing) from, into, and between the year 1999 and the year
               2000, including leap year calculations, when used in accordance
               with the product documentation provided by Motorola, provided
               that all listed or unlisted products (e.g., hardware, software,
               firmware) used in combination with such listed product properly
               exchange date data with it. This warranty shall extend to
               date-related defects discovered through January 1, 2001. Customer
               must notify Motorola, in writing, no later than January 1, 2001
               of Product that does not conform to this Express Warranty. The
               remedied available for breach of this warranty shall be as
               defined in, and subject to, the terms and limitations of Sections
               8.1 through 8.5 and Section 8.7. Except as provided herein,
               nothing in this warranty statement shall be construed to limit
               any rights or remedies provided elsewhere in this Agreement with
               respect to matters other than Year 2000 performance.

        8.7    THE WARRANTIES IN THIS AGREEMENT ARE GIVEN IN LIEU OF ALL OTHER
               WARRANTIES, EXPRESS OR IMPLIED, WHICH ARE SPECIFICALLY EXCLUDED,
               INCLUDING, WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY AND

               LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL OR
               PUNITIVE DAMAGES TO THE FULL EXTENT SUCH MAY BE DISCLAIMED BY
               LAW.

               MOTOROLA WARRANTS THAT FOR THE TERM OF THIS AGREEMENT THAT THE
               INDIVIDUAL FNE PRODUCTS WILL OPERATE TOGETHER AS A SYSTEM WITHIN
               GENERAL OPERATING LIMITS SPECIFIED IN EXHIBIT "B", SO LONG AS THE

9.0     PRODUCT CHANGES OR SUBSTITUTIONS

               At any time during its performance of this Agreement, Motorola
               may implement changes in the products set forth in Exhibit "B",
               modify the drawings and specifications relating thereto, or
               substitute therefor products of more recent design; provided,
               however, that any such changes, modifications or substitutions,
               under normal and proper use:

                      (1)    shall not materially or adversely affect physical
                             or functional interchangeability or performance
                             (except where there is written agreement between
                             Customer and Motorola that the change can be made
                             after Customer knows the effect thereof);

                      (2)    shall not detract from the safety of the product;
                             and

                      (3)    shall be Spectrum Regulatory Agency type-accepted,
                             if required.

                      (4)    Motorola shall notify Customer of any change that
                             materially affects performance of the Equipment.

10.0    DISCLAIMER OF PATENT LICENSE AND INTERFACE LICENSES

        10.1   Nothing contained in this Agreement shall be deemed to grant,
               either directly or by implication, any license under any patents
               or patent applications of Motorola, except that Customer shall
               have the normal non-exclusive royalty-free license to use which
               is implied, or otherwise arises by operation of law, in the sale
               of a product.

         10.2  If Nextel Communications, Inc. obtains a second source for iDEN
               infrastructure Equipment, Motorola shall extend Interface
               Licenses to qualified licensees on terms to be negotiated to
               cover Customer.

11.0    INTELLECTUAL PROPERTY INDEMNITY

        11.1   Motorola shall defend Customer against a claim that
               Motorola-manufactured products or latest unmodified release of
               Software supplied hereunder infringe a [See schedule Item 3 ]
               patent or [See schedule Item 3 ] copyright, provided that (i)
               Customer promptly notifies Motorola in writing of the claim, (ii)
               Motorola has sole control of the defense and all related
               settlement negotiations, and (iii) Customer gives Motorola
               information and assistance for the defense of all at Motorola's
               expense provided, however, that Customer's failure to provide
               such

               notice shall not relieve Motorola of liability under this Section
               11 except to the extent Motorola was prejudiced thereby. Subject
               to the conditions and limitations of liability stated in this
               Agreement, Motorola shall indemnify and hold Customer harmless
               from all payments which by final judgments in such suits may be
               assessed against Customer on account of such infringement and
               shall pay resulting settlements, costs and damages finally
               awarded against Customer by a court of law.

        11.2   Customer agrees that if Equipment or Software become, or in
               Motorola's opinion are likely to become, the subject of such a
               claim, Customer will permit Motorola, at its option and expense,
               either to procure the right for Customer to continue using such
               Equipment or Software or to replace or modify same so that they
               become non-infringing without affecting the function and
               capability, and if neither of the foregoing alternatives is
               available on terms which are reasonable in Motorola's judgment,
               Customer can return Motorola-manufactured products and/or
               Software for full credit on the entire unusable portion thereof.

        11.3   Motorola has no liability for any claim of patent or copyright
               infringement to the extent based upon adherence to
               specifications, designs or instructions furnished by Customer,
               nor for any claim based upon the combination, operation or use of
               any Motorola-manufactured products or Software supplied hereunder
               with products, software or data not supplied by Motorola, nor for
               any claim to the extent based upon alteration of the products or
               modification of any software supplied by entities other than
               Motorola.

12.0    CONFIDENTIALITY

        12.1   From time to time during the performance of this Agreement, the
               parties may deem it necessary to provide each other with
               Confidential Information. The parties agree:

               12.1.1 To maintain the confidentiality of such Confidential
                      Information and not disclose same to any third party,
                      except as provided below or as authorized by the original
                      disclosing party in writing, or in connection with a
                      public or private debt or equity offering of securities by
                      any party or its affiliates, or as required by law or a

                      such information that Motorola believes is confidential
                      Customer will use its reasonable best efforts to get
                      confidential treatment from the SEC and the [See schedule

                      who have a "need to know". Such Confidential Information
                      shall be handled with the same degree of care which the

                      informing its employees and consultants who handle such
                      Confidential Information that it is confidential and not
                      to be disclosed to others and as to all technical
                      consultants obtain a signed non-disclosure agreement
                      consistent herewith.

               12.1.4 That Confidential Information is and shall at all times
                      remain the property of the disclosing party. No use of any
                      Confidential Information is permitted except as otherwise

14.0    SHIPMENT, DELIVERY AND PACKING

        14.1   Motorola may ship products at any time during the "Time Frame"
               (the interval between the shipment/implementation date and the
               completion date for a particular activity as set forth in the
               Implementation Schedule) and may invoice Customer upon shipment
               as provided in Section 6 of this Agreement. No shipment of
               products during said Time Frame shall be considered early for
               purposes of invoicing.

        14.2   Customer shall select the carrier and notify Motorola in writing
               or instruct Motorola to use the best available carrier or the
               carrier most recently used by Customer, unless Customer notifies
               Motorola not to use such carrier.

        14.3   Motorola shall use all reasonable efforts to ship products
               directly to the Site or Customer designated warehouse.

        14.4   In the event that the Site or Customer designated warehouse is
               not available to receive Equipment because Customer has not met
               its obligations hereunder to receive the products when shipped,
               Motorola, at its option, upon notice to Customer, may ship said
               products to a warehouse in or near the area as designated by
               Customer, and Customer shall bear the costs of warehousing,
               reloading, transporting, off-loading and moving the products onto
               the Site when such Site becomes available.

        14.5   Shipping documentation shall be developed to the mutual
               satisfaction of Customer and Motorola. Shipping terms are FCA
               manufacturing site or Motorola facility. The manufacturing site
               may be other than a USA facility.

        14.6   Motorola shall have the Equipment securely packed so as to
               withstand numerous handlings and loading as appropriate for
               inland, sea and/or air transportation. Motorola shall take
               reasonable protective measures to protect Equipment from weather
               and shock, considering the different shapes and special features
               of the Equipment.

15.0    TITLE, INDEMNITY, INSURANCE

        15.1   Good title, free and clear of all liens or other encumbrances to
               the FNE and other Motorola provided products supplied hereunder
               and risk of loss for all such products shall pass to Customer
               upon delivery FCA point of shipment.

        DISCLAIMED BY LAW.

19.0    ASSIGNMENT - RESALE OF EQUIPMENT

        19.1   Any re-sale of Equipment will require a re-licensing of the
               Software from Motorola, including payment of an IPL license fee
               by the new owner. Motorola reserves the right to relicense the
               software in countries Motorola is concerned over intellectual
               property rights or to users not approved by Motorola. Any
               sale-leaseback of equipment by the Customer will not require
               re-licensing or IPL Licensing fees and Motorola will cooperate
               with leasing company, as in the past, to provide appropriate
               waivers. Re-licensing and to qualifying international affiliates
               under Section 4.22 of the iDEN Infrastructure [*] Supply
               Agreement effective as of January 1, 1999 between Motorola, Inc.
               and Nextel Communications, Inc. shall be based upon rework fees
               and other expenses Motorola incurs, if any.

        19.2   The Agreement shall accrue to the benefit of and be binding upon
               the parties hereto and any successor entity into which either
               party shall have been merged or consolidated or to which either
               party shall have sold or transferred all or substantially all its
               assets. Specifically, Motorola may assign this Agreement,
               provided that Motorola, Inc. shall remain liable for performance
               hereunder. This Agreement shall not be otherwise assigned by
               either party without the prior written consent of the other
               party. In conjunction with any agreed to assignment of this
               Agreement, Motorola agrees to license the assignee pursuant to
               the terms set forth in Exhibit "F". A reasonable new Software
               License Fee may be required of any successive owner of iDEN
               infrastructure Equipment.

        19.3   Notwithstanding anything to contrary elsewhere in this Agreement,
               Customer may pledge, mortgage or otherwise assign all or any
               portion of this Agreement or any orders hereunder (or any
               combination thereof) to one or more providers of debt or equity
               financing (provided any such intended assignee is not a person or
               entity listed on the United States Department of Commerce Denied
               Parties List or to a person or entity residing in a country to
               which export of the iDEN Equipment is prohibited under United
               States law) upon terms and conditions satisfactory to Customer,
               provided that (i) Customer will remain liable for all obligations
               arising out of this Agreement, (ii) the assignee agrees in
               writing that the terms and conditions of this Agreement shall
               apply to and be binding upon the assignee to the same extent as
               Customer, to the extent that the assignee is exercising any right
               under this Agreement, (iii) in addition to any rights conferred
               on the assignee, and

               Customer shall be treated as having placed the order and paid for
               purchases for purposes of all rights and benefits available to
               Customer under this Agreement.

        19.4   Motorola retains the right to subcontract, in whole or in part,
               any effort required to fulfill its obligations under this
               Agreement, provided Motorola shall remain liable for performance
               hereunder.

        19.5   Any resale of the FNE to a third party shall be subject to
               Motorola's approval, which shall not be unreasonably withheld and
               shall require execution of a Software License between Motorola
               and such third party and payment of a reasonable Software License
               fee.

        19.6   The parties acknowledge that the resale restrictions herein apply
               to infrastructure equipment only. The subscriber Agreement deals
               with subscriber unit warranty and licensing pass through.
               However, it is understood that Subscriber Units are expected to
               be sold to end users.

        20.0   SWITCH IN TECHNOLOGY

               20.1   If Customer determines that iDEN technology is no longer
                      suited to its needs in part or in whole and consequently
                      commercially viable to provide reliable digital dispatch,
                      short message service, voice interconnect, circuit
                      switched data and packet data services, Customer shall
                      give notice of such determination to Motorola describing,
                      with reasonable specificity any technology failure(s)
                      and/or the reasons for Customer's determination at least
                      six (6) months in advance of any public announcement or
                      formal contract to purchase alternate technology
                      ("Alternate Technology").

               20.2   In the case of a switch to an Alternate Technology that
                      Motorola manufactures or elects to manufacture, Customer
                      shall give Motorola the opportunity to supply Fifty
                      Percent (50%) of Customer's needs of the Alternate
                      Technology for infrastructure equipment of the Alternate
                      Technology for a period of three (3) years following a
                      public announcement to change the technology.

               20.3   If Customer makes a switch to Alternate Technology and
                      Customer fails to maintain operational iDEN infrastructure
                      equipment at the majority of its commercial cell sites
                      deployed at the date such switch is first publicly
                      announced, all financing outstanding by Motorola or its
                      affiliates to Customer and its wholly owned or controlled

        23.2   Either party may change the addresses for giving notice from time
               to time by written instructions to the other of such change of
               address.

24.0    SURVIVAL OF PROVISIONS

        The parties agree that where the context of any provision indicates an
        intent that it shall survive the term of this Agreement then it shall
        survive.

25.0    COVENANT NOT TO SOLICIT EMPLOYMENT

        Customer and Motorola hereto agree that during the period of time
        beginning with the execution of this Agreement and ending with the
        termination of this Agreement, neither party shall solicit any employee
        of the other involved in providing engineering, installation,
        integration, maintenance, and/or warranty service or to encourage such
        employee to work for the other. If, at any time, this provision is found
        to be overly broad under the laws of an applicable jurisdiction, this
        provision shall be modified as necessary to conform to such laws rather
        than be stricken herefrom.

26.0    GENERAL

        Failure or delay on the part of Motorola or Customer to exercise any
        right, power, or privilege hereunder shall not operate as a waiver. If
        any provision of this Agreement is contrary to, prohibited by or held
        invalid by any law, rule, order, or regulation of any government or by
        the final determination of any state or federal court, such invalidity
        shall not affect the enforceability of any other provisions not held to
        be invalid. Section and paragraph headings used in this Agreement are
        for convenience only and are not to be used to construe the provisions
        of this Agreement.

27.0    AUTHORITY

        Each party hereto represents and warrants that:

        27.1   It has obtained all necessary approvals, consents and
               authorizations of third parties and governmental authorities to
               enter into this Agreement and has obtained or will obtain all
               necessary approvals, consents and authorizations of third parties
               and governmental authorities to perform and carry out its
               obligations hereunder;

        27.2   The persons executing this Agreement on its behalf have express
               authority to do so, and, in so doing, to bind the party thereto;

        27.3   The execution, delivery, and performance of this Agreement does

        27.4   The execution, delivery, and performance of this Agreement has
               been duly authorized by all necessary partnership or corporate
               action and this Agreement is a valid and binding obligation of
               such party, enforceable in accordance with its terms.

28.0    TERM

        The term of this Agreement shall be from June 30, 2000 until December
        31, 2003 unless an Exhibit provides otherwise.

29.0    RE-EXPORTATION OF TECHNICAL DATA OR PRODUCTS

        Customer understands that all equipment, proprietary data, know-how,
        software, or other data or information obtained by Customer from
        Motorola is considered to be United States technology and is licensed
        for export and re-export by the United States Government. Customer
        therefore agrees that it will not, without the prior written consent of
        Motorola and the Office of Export Control, United States Department of
        Commerce, Washington, DC 20230, USA, knowingly export, re-export, or
        cause to be exported or re-exported, either directly or indirectly, any
        such equipment, proprietary data, know-how, software, or other data or
        information, or any direct or indirect product thereof, to any
        destination prohibited or restricted under United States law. Customer
        understands that the list of prohibited or restricted destinations may
        be amended from time to time by the United States Department of Commerce
        and that all such amendments shall be applicable to this Agreement.

30.0    DISPUTES AND DISPUTE RESOLUTION

        The parties will attempt to settle any claim or controversy arising out
        of this Agreement through consultation and negotiation in good faith and
        a spirit of mutual cooperation. If those attempts fail, then, except for
        disputes related to alleged patent, copyright, or trademark
        infringement, the dispute will be mediated by a mutually acceptable
        mediator to be chosen by the Motorola and Customer within thirty (30)
        days after written notice by the other demanding mediation. Neither
        party may unreasonably withhold consent to the selection of a mediator,
        and Motorola and Customer will share the costs of the mediation equally.
        Venue for mediation shall be the United States of America. By mutual
        agreement, however, the parties may postpone mediation until they have
        each completed some specified but limited discovery about the dispute.
        The parties may also agree to replace mediation with some other form of
        alternative dispute resolution (ADR), such as neutral fact-finding or a
        mini-trial.

        Any dispute which the parties cannot resolve through negotiation,
        mediation, or other form of ADR within four (4) months of the date of
        the initial demand for it may then be submitted to the Federal District
        Court of Delaware for resolution. The use of any ADR procedures will not
        be construed under the doctrines of latches, waiver, or estoppel to
        affect adversely the rights of either party. Nothing in this section
        will prevent either party from resorting to judicial proceedings if (a)
        good faith efforts to resolve the dispute under these procedures have
        been unsuccessful or (b) interim relief from a court is necessary to
        prevent serious and irreparable injury to one party or to others.

31.0    LANGUAGE

        The definitive text of this Agreement and its Exhibits shall be in
        English and all communications among the parties in the course of the
        present Agreement shall be made in English.

32.0    GOVERNMENT CONTRACTS

        In the event that Customer elects to provide goods or services to a
        Governmental Entity (defined herein), Customer does so solely at its
        option and risk and agrees not to obligate Motorola as a subcontractor
        or otherwise to such Governmental Entity. Customer remains solely and
        exclusively responsible for compliance with all statutes, regulations,
        and provisions governing sales to such entity. Motorola makes no
        representations, certifications, or warranties whatsoever with respect
        to the ability of its goods, services, or prices to satisfy any
        statutes, regulations, or provisions governing sales of goods or
        services to such Governmental Entity. The term "Governmental Entity" as
        used above

        includes any government agency, federal, provincial, or municipal, any
        United States federal, state, or local government, agency, or
        instrumentality as well as any other non-United States government,
        agency, or instrumentality. Notwithstanding the above, if Customer
        elects to sell goods or services to a Governmental Entity, Motorola will
        review any Customer request for, readily available information which
        Motorola may, at its option supply.

33.0    SEVERABILITY

        In the event that any one or more of the provisions contained in the
        Agreement or in any of the Exhibits hereto should be determined to be
        invalid, illegal, or unenforceable in any respect, the validity,
        legality, and enforceability of the remaining provisions shall not in
        any way be affected or impaired. The parties shall endeavor in good
        faith to replace any invalid, illegal, or unenforceable provision with a
        valid provision, the economic effect of which comes as close as possible
        to that of the invalid, illegal, or unenforceable provision.

34.0    ENTIRE AGREEMENT

        This Agreement and the Exhibits hereto constitute the entire
        understanding among the parties concerning the subject matter hereof and
        supersede all prior discussions, agreements, and representations,
        whether oral or written, and whether or not executed by the parties. The
        subject matter of this Agreement is iDEN Infrastructure Equipment
        purchases. Documents or agreements relating to the parties' equity
        ownership in each other, if any, Customer's purchases of Subscriber
        Equipment or Motorola financing agreements are not superseded by this
        Agreement. The Equipment and Services purchased on or before June 30,
        2000 under the terms and conditions of the [See schedule Item 4 ] shall
        be governed by such agreements. The terms and conditions for use of all
        Software, whenever purchased, shall be as set forth in this Agreement.
        All Equipment, Software and Services purchased on or after June 30, 2000
        shall be governed by the terms and conditions of this Agreement.

        No modification, Amendment, or other change may be made to this
        Agreement or any Exhibit unless reduced to writing and executed by
        authorized representatives of all parties, or in the case of a Change
        Order executed by authorized representatives of Customer and Motorola.

        The terms and conditions of this Agreement shall prevail notwithstanding
        any variance with the terms and conditions of any order submitted by
        Customer or any acceptance or acknowledgment by Motorola following
        execution of this Agreement. In no event shall the preprinted terms and
        conditions found on any Customer purchase order, Motorola
        acknowledgment, a Change Order, or other form be considered an
        Amendment, or

35.0    COUNTERPARTS

        This Agreement may be executed in multiple counterparts, each of which
        shall be deemed an original and all of which taken together shall
        constitute one and the same instrument.

For purposes of uniformity and brevity, references to "Agreement" or "Purchase
Agreement" or to an Exhibit shall refer to the above-referenced Agreement to
which this document is Exhibit "A" and to the other Exhibits to that Agreement.
All definitions set forth in the Agreement shall apply hereto.


1.0    PROJECT AGREEMENT PROCESS

The scope of a Project is limited to the Purchase Orders and the Motorola
Generic Statement of Work referenced in the Project Agreement. The Project
Agreement is intended neither as a reconciliation document nor as a means to
purchase Equipment, Software, and/or Services. All financial transactions shall
be conducted in accordance with the applicable Purchase Orders. A Project
Agreement format and example are attached to this Exhibit "A" as Appendices I
and II, respectively.

1.1    Upon acceptance of one or more Purchase Orders containing a grouping of
items that meets the definition of a System or System Expansion, Motorola shall
initiate a Project Agreement.

1.2    A Motorola Generic Statement of Work that defines the Project shall be
selected from the Price Book and referenced in Section I of the Project
Agreement. In the event an appropriate statement of work is not included in the
Price Book, a custom statement of work shall be incorporated into the Project
Agreement. The project Generic ATP sections will be listed in Section IV of the
Project Agreement.

1.3    The Purchase Order number(s), applicable line items, and values shall be
referenced in Section II of the Project Agreement for identification purposes
only. The total value of the Project Agreement shall reflect the System or
System Expansion requirements as described in the Customer Purchase Order(s).

1.4    Motorola does not warrant that a Project Agreement will contain all
necessary requirements for completion of the specific System or System Expansion
Project stated in the Project Agreement. Motorola is responsible only for the
Equipment, Software, and Services set forth and provided by Customer in the
Purchase Orders issued for the Project. Additional Purchase Orders will be
required and incorporated into the Project Agreement by amendment, as

4.7    Special Consideration for System Expansions

The ATP for a System Expansion may contain a subset of the acceptance tests for
a System and will be dependent upon the Equipment and Software purchased in the
System Expansion.

4.8    Conditional Acceptance

In the event that commercial service has not yet commenced, ATP -- Conditional
Acceptance for a System or System Expansion shall occur when Motorola has
completed and passed, to mutual agreement, the applicable ATP tests. ATP --
Conditional Acceptance shall not be delayed because of minor (level 4 or below)
test failures. Such defects may be placed on the punchlist for later resolution.
In the event of major test failures caused by level 6 or above defects,
completion of the ATP will be delayed until each such defect is corrected and
the item retested. Defects caused by systemic Software issues that are not
service affecting are covered under the Software Maintenance Program (SMP).

4.9    Customer Performance Test Period

       a) Upon completion of the ATP, a Punchlist shall be mutually developed
          within [*]. In addition, a [*] Performance Test Period shall commence
          immediately following successful completion of the ATP -- Conditional
          Acceptance test procedures, to allow Customer to operate the System
          to determine if additional failures are found as a result of Motorola
          products failure to operate as specified.

       b) Prior to completion of the [*] test, Customer may load the System or
          System Expansion for a period not to exceed [*] (unless otherwise

When substantially all Punchlist Items (including all Level 6 and above defects)
are resolved , ATP -- Final Acceptance shall be granted. Such approval shall not
be unreasonably withheld. ATP -- Final Acceptance shall be evidenced by a letter
of acceptance provided by Motorola and signed by Customer.


6.0    ACCEPTANCE GUIDELINES

6.1 In the event that, due to a problem outside Motorola's control, a particular
test or group of tests cannot be completed within the time scheduled, one of
these procedures will be implemented:

       a)  The affected test or portion of a test may be interrupted and
           rescheduled for completion or retesting at some future time.

       b)  The affected test or portion of a test may be continued to
           completion and the Acceptance Test schedule amended as required to
           accommodate the remaining tests and the exceptions that failed the
           original testing.

       c)  If the problem results from Customer action or inaction or due to
           non-performance of a Customer responsibility, the affected test will
           be rescheduled and any additional costs will be borne by Customer.

Motorola will confer with Customer and decide, on a case by case basis, which of
these procedures is appropriate and notify Customer.

6.2    In the event of Customer-caused delays in the implementation of a System
or System Expansion, ATP -- Conditional Acceptance shall be deemed granted 60
days after the ATP -- Conditional Acceptance date set forth in the Project
Implementation Schedule and all payments associated with ATP -- Conditional

Implementation Schedule and all payments associated with ATP -- Final Acceptance
shall be due and payable as of this date.


7.0    REPORTING RESULTS AND RETESTING

7.1    Test Sequencing

At the completion of each test, a pass/fail determination will be made based on
the performance of FNE Equipment supplied by Motorola and subject to Acceptance
Testing under the Agreement. In the event of test failure, other tests not
effected by the failed test will not be delayed and can continue while remedies
are prepared for the failed test. Failed test procedures will be scheduled for
retesting as appropriate

7.2    Regression Testing

After a test failure has been remedied it will be scheduled for retest. Previous
tests that have passed and that logically could be affected by the remedy for
the failed test will be repeated. Previously passed tests that are logically
unaffected by the remedy for the failed test do not require retesting. Motorola
will determine whether a test is or is not logically affected by any remedy.

7.3    Test Failure Severity Levels

The following table defines the Test Severity Levels to be used in recording
Test Results:

        5.5    Customer may purchase Motorola FNE additions required to
               accommodate new features and/or functionality at an additional
               charge to Customer as set forth in the iDEN Infrastructure Price
               Book. Motorola shall notify Customer of any additional hardware
               requirements as soon as they are aware that such additional
               hardware is necessary. Motorola failure to notify Customer of
               material changes in hardware, when known prior to Customer order
               of such features or functions, will result in cancellation of the
               original order and allowance for the Customer to reconsider its
               wish to proceed.

        5.6    After completion of an SMP coverage period, if Customer declines
               to purchase and extend the SMP for a future term or if Customer
               terminates a subsequent SMP and thereby allows SMP coverage to
               lapse for a System, Motorola must certify (as described in
               Section 5.7 herein) the System before Motorola will make the SMP
               available to Customer for such System for another term.

        5.7    Certification for SMP consists of the following: (1) Motorola
               will audit Customer's System at Customer's expense; (2) Motorola
               will identify the FNE and/or IPL that must be purchased by
               Customer, if any, in order to bring Customer's System to the
               current release level (this includes back payment of all lapsed
               SMP); (3) Customer must acquire such FNE and/or IPL; and (4) once
               Customer has purchased the necessary items, Motorola will certify
               Customer's System and make SMP available to Customer at the then
               current Motorola price.

        5.8    While Customer is enrolled in the SMP, Motorola shall provide all
               labor necessary to correct any service-affecting Software defects
               for the full warranty period and for any period the Software is
               covered by the SMP, without charge to Customer, and in accordance
               with the warranty provisions contained in Exhibit "F".

        5.9    During the period SMP is purchased by Customer, Motorola shall
               provide the services defined in Schedule A (Telephone Technical
               Support) under SMP.

        5.10   Customer shall be responsible for the first level of maintenance,
               including but not limited to diagnosis and isolation of
               reproducible Software malfunctions. In the event of any such
               Software malfunction, Customer shall notify Motorola immediately,
               followed by written confirmation of such notice. Motorola will
               acknowledge receipt of verified reproducible Software
               malfunctions and will promptly provide such service as is
               necessary to correct service-affecting defects in accordance with
               the published Motorola specifications. Customer shall be
               responsible for the installation of new Releases, Updates and
               associated Firmware.

        5.11   SMP applies only to the Software as supplied or modified by
               Motorola. Modifications, attempted modifications, or additions to
               the Software by Customer or by any party other than Motorola is a
               breach of the Software License contained in Exhibit "F" to the
               Purchase Agreement and will void all obligations of Motorola
               under the SMP.

        5.12   Motorola shall have no obligation to support any Software other
               than the current Release and the immediately preceding Major
               Release.

        5.13   The SMP supplied to Customer during the warranty period shall be
               automatically renewed on a yearly basis.

        5.14   Customer shall agree to yearly audits by Motorola of Systems
               configurations and capacities in order to calculate the new SMP
               price. The new SMP price for the following year shall be
               calculated at the end of each calendar year and shall be based on
               the Products in Commercial Service at that time. If Customers'
               initial SMP coverage expires prior to December 31, the renewal
               period shall expire on December 31, and Customer shall be charged
               for the pro rata amount of the SMP fee to cover the period from
               expiration to December 31 of that year. The next renewal period
               shall begin on January 1 of the next year.

5.15           The Software Maintenance Program (SMP) Proposal set forth in
               Exhibit "O" shall be subject to the terms and conditions of the
               Agreement into which this Exhibit "E" is incorporated. The
               following statement in the "Additional Terms and Conditions"
               subsection of Section 4 to Exhibit "O" is therefore superceded:



                   Except as modified herein, all terms and conditions of the
                   [See schedule Item 4] shall apply to any resultant Purchase
                   Order and shall supersede and replace any preprinted terms
                   and conditions contained on said Purchase Order.

6.      SCHEDULE D:  OPTIONAL LOCAL ENGINEERING SUPPORT SERVICES

        The following Service option is offered by Motorola to Customer
        concurrently with the maintenance service contained in Schedules A
        through C during the warranty period and may be extended on an annual
        basis.

      does not cover the use of any Optional Features. This fee also does not
      cover the use of Software on expansion equipment associated with Network
      Elements, unless such expansion equipment is installed when Customer pays
      the Initial License Fee.

      License Fee - License Fee means the fee paid by Customer pursuant to
      Section 6.1.4 of the Agreement for the right to use Software in accordance
      with the terms of this Exhibit.

      Network Elements - Network Elements refer to the network infrastructure
      components, including those components associated with Internet Protocol
      (IP) network architecture. Network Elements include, but are not limited
      to, the Fixed Network Equipment (FNE), and any expansions or
      sub-components thereof. Network Elements may be either manufactured or
      supplied by Motorola or by third parties.

      Network Features - Network Features allow specialized communication
      between any Network Elements.

      Operating System Software (O/SS) - The O/SS brings the hardware platform
      to a state of readiness that allows Standard and Optional Features to run.

      Operational Features - Operational Features improve the overall non-call
      performance of the network. Non-call performance includes increased call
      quality, increased availability and decreased cost of ownership. Examples
      of Operational Features include Billing Features, CAMP Terminal

             only) in whole or in part, in machine-readable form for Customer's
             internal use only, provided, however, that no more than two (2)
             printed copies and two (2) machine-readable copies will be in
             existence at any one time without the prior written consent of
             Motorola, other than copies resident in the System Configuration.

      4.2    With reference to any copyright notice of Motorola associated with
             Software, Customer agrees to include the same on all copies it
             makes in whole or in part. Motorola's copyright notice may appear
             in any of several forms, including machine-readable form. Use of a
             copyright notice on the Software does not imply that such has been
             published or otherwise made generally available to the public.

      4.4    Software and any copy of Software is the sole and exclusive
             property of Motorola or its licensors and no title or ownership
             rights to the Software or any of its parts is transferred to
             Customer.

      4.5    Customer acknowledges that it is the responsibility of Customer to
             take all reasonable measures to safeguard Software and to prevent
             its unauthorized use or duplication.

5.    REMEDIES

      Customer acknowledges that violation of the terms of this Exhibit or the
      Agreement shall cause Motorola irreparable harm for which monetary damages
      may be inadequate, and Customer agrees that Motorola may seek temporary or
      permanent injunctive relief without the need to prove actual harm in order
      to protect Motorola's interests.

             TO iDEN(R) INFRASTRUCTURE EQUIPMENT PURCHASE AGREEMENT


                                    TRAINING

For purposes of uniformity and brevity, references to Agreement or to an Exhibit
shall refer to the above-referenced Agreement to which this document is Exhibit
"G" and to the other Exhibits to that Agreement. All definitions set forth in
this Agreement shall apply hereto. Payment of the fee set forth in the then
current iDEN Training Catalog shall evidence incorporation of this Exhibit "G"
into the Agreement.

Technical Training is intended for System Operators, Maintenance personnel,
Supervisor and Management personnel responsible for operation of an iDEN System
who possess the necessary prerequisite knowledge, including but not necessarily
limited to knowledge of telephony, digital communications and networking, logic
circuitry, Pulse Code Modulation theory, and RF Technology.

1.0     GENERAL

        1.1    The series of sub-component courses presented in the iDEN
               Training Catalog are primarily intended for delivery at the iDEN
               Technical Training Center in Schaumburg, IL, using dedicated
               training equipment and training facilities. Some level 1 courses
               can be delivered at the Customer premises.

        1.2    The training pricing shown in the iDEN Training Catalog includes
               all instructional services and student course materials for use
               by Customer's students. No license is granted for further
               reproduction or distribution of these Motorola developed training
               materials provided during the class sessions.

        1.3    All training will be conducted in English and all course material
               will be in English, unless otherwise agreed  by both parties

        1.4    For classes conducted at Motorola facilities in Schaumburg, IL,
               any and all other expenses incurred by Customer's student
               attendees, including but not limited to travel, meals, lodging
               and personal entertainment, are the responsibility of Customer or
               the attendee.

        1.5    For instructional services, consulting, or classes conducted at a
               Customer-supplied facility, or for any location other than
               Motorola facilities in Schaumburg, IL, Customer shall be
               responsible for the payment of all incidental expenses resulting
               from the training session. This would include but not be limited
               to facilities costs such as meeting room costs or equipment

               conducted at Customer location will utilize customer-supplied
               product, terminals, test equipment and related paraphernalia for
               the practical "Hands-On" sessions. Motorola reserves the right to
               subcontract training to authorized Motorola training departments
               outside of the Network Solutions Sector (NSS), and/or
               subcontractors of Motorola.

2.0     TECHNICAL TRAINING PLAN DESCRIPTION

        2.1    One of the many initiatives of iDEN technical training is to
               provide training that will help Customer participants perform
               their jobs more efficiently. To do this, Motorola's technical
               training representatives interviewed managers, and more
               importantly, the technicians and engineers who actually do the
               work to find out what the Customer's needs are to maintain the
               iDEN infrastructure.

        2.2    The Technical Training Curriculum is divided into 3 levels.

                   A.  Level 1 is for someone new to the MSO environment

                   B.  Level 2 is designed to train individuals how to maintain
                       and troubleshoot the infrastructure.

                   C.  Level 3 will teach the technicians and engineers advanced
                       concepts and troubleshooting techniques.

               All equipment maintenance courses will be structured to provide
               servicing information consistent with the service plan
               established by Motorola. No component level servicing information
               is included in this training plan for any Fixed or Subscriber
               equipment within this System.

3.0     SCHEDULING OF TRAINING

        The training curriculum available in the iDEN Training Catalog will be
        accompanied by the schedule for all of the classes held in the Motorola
        Training facility in Schaumburg, IL. Training that can be delivered at
        the Customer location will be scheduled depending on instructor
        availability and the acceptance of the proposed quote. These field
        classes may be subject to change based on resource, equipment, and
        System availability. To ensure a wider range of available training
        dates, scheduling requests should be made at least 120 days in advance
        of the start of the requested delivery date. At the time of Customer's
        request for scheduling, Motorola will confirm the request and will
        inform Customer of changes that may have occurred in course length,
        delivery location, content or source that would materially affect the
        training session.

4.0     DELIVERABLES FOR TECHNICAL TRAINING AND TECHNICAL TRAINING-RELATED
        PRODUCTS

        The Curriculum list in the iDEN Training Catalog shows the course titles
        for each of the expected classes in each of the three training levels.
        The lists of training courses are subject to revision, based on changes
        in Customer's System hardware and software. In addition, training course
        title, content, source and desired location is subject to change.

5.0     TECHNICAL TRAINING PREREQUISITES

        Each of the courses or course levels shown in the catalog has one or
        more prerequisites.

        In general, if a course is to be taken without completing the suggested
        prerequisites for that particular course, the prerequisite waiver form
        located in the catalog must be completed and attached to the
        registration form. The filling out of this waiver form indicates that
        the specified individual has the equivalent experience, and/or knowledge
        base, to assimilate the course content without completing the suggested
        prerequisites. It also indicates that the individual is registering
        without having taken the prerequisites but is part of the target
        audience.

6.0     COURSE DESCRIPTIONS

        The course descriptions set forth in Motorola's Training Catalog shall
        be considered a representative sample of the courses available to
        Customer. All material in the catalog is subject to change.
