          (g) Cure of Event of Default. Without limiting the obligations of the
     Borrower under Sections 7.08(a), (b) and (e), a breach by the Borrower as
     of the last day of any fiscal quarter or any fiscal year of its obligations
     under said Sections shall not constitute an Event of Default hereunder
     until the date (the "Cut-Off Date") which is the earlier of the date thirty
     days after (a) the date the financial statements for the Borrower and its
     Subsidiaries with respect to such fiscal quarter or fiscal year, as the
     case may be, are delivered pursuant to Section 6.01(a) or 6.01(b) or (b)
     the latest date on which such financial statements are required to be
     delivered pursuant to Section 6.01(a) or 6.01(b), provided that, if
     following the last day of such fiscal quarter or fiscal year and prior to
     the Cut-Off Date, the Borrower shall have received Equity Contributions in
     an amount sufficient to bring the Borrower into compliance with said
     Sections 7.08(a), (b) and (e), assuming that the Leverage Ratio, Interest
     Coverage Ratio or amount of the revenues (as the case may be), as of the
     last day of such fiscal quarter or fiscal year, as the case may be, were
     recalculated by adding the amount of such Equity Contributions to (i) the
     denominator of the Leverage Ratio (after giving effect to the
     multiplication set forth in the definition thereof), (ii) the numerator of
     the Interest Coverage Ratio (after giving effect to the multiplication set
     forth in the definition thereof) or (iii) the amount of the revenues of the
     Borrower and its Subsidiaries, then such breach or breaches shall be deemed
     to have been cured; provided, further, that breaches of Sections 7.08(a),
     (b) or (e) hereof may not be deemed to be cured pursuant to this Section
     7.08(g) (x) more than twice during the term of this Agreement or (y) during
     consecutive fiscal quarters."

                   AMENDMENT NO. 1 TO THE AMENDED AND RESTATED
                         CAPITAL SUBSCRIPTION AGREEMENT

     AMENDMENT NO. 1 dated as of June 20, 2000, made by and among (i) NEXTEL
ARGENTINA S.R.L. (the "Borrower"), a sociedad de responsabilidad limitada
organized under the laws of Argentina, (ii) NEXTEL INTERNATIONAL (ARGENTINA),
LTD. (the "Parent"), a company incorporated under the laws of the Cayman
Islands, and (iii) NEXTEL INTERNATIONAL, INC. (the "Parent Shareholder"), a
corporation organized under the laws of the State of Washington, United States
of America.

     The Borrower, the Parent and the Parent Shareholder are parties to a
Capital Subscription Agreement dated as of March 17, 1998 (as amended and
restated by the Amended and Restated Capital Subscription Agreement dated as of
May 12, 1999 and as further modified, supplemented and in effect from time to
time, the "Capital Subscription Agreement") and wish to amend certain provisions
of the Capital Subscription Agreement.

     Accordingly, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:


     SECTION 1. Amendments.

     1.01. Definitions. The definition of "Equity Contribution" in Section 1 of
the Capital Subscription Agreement is hereby amended to read in its entirety as
follows:

          "Equity Contribution" means, as to any Person (i) the amount of cash
     consideration paid to such Person in exchange for newly-issued Capital
     Stock of such Person, (ii) the amount of any contribution of cash to such
     Person in respect of its Capital Stock made by any then-existing
     equityholder, (iii) in the case of the Borrower, the value of equipment
     contributed to the Parent by the Parent Shareholder, and to the Borrower by
     the Parent, in respect of its capital stock, so long as such equipment is
     newly manufactured and has been purchased by the Parent Shareholder from
     third party vendor(s), not an Affiliate, within 30 days prior to the date
     of delivery of such equipment to the Borrower and (iv) the value of
     payments made by the Parent Shareholder to third party vendors in respect
     of software, software design and software licensing utilized by the
     Borrower and its Subsidiaries and set forth in a certification to such
     effect delivered to the Administrative Agent and signed jointly by an
     officer of the Parent Shareholder and the Borrower, provided that the
     aggregate amount of such payments during any single fiscal year that may be
     treated as Equity Contributions shall not exceed U.S. $3,000,000. For
     purposes hereof, the value of any equipment contributed to the Parent and
     the Borrower as contemplated by the foregoing clause (iii) shall be valued
     at the purchase price therefor reflected on the invoice of the respective
     vendor, and the value of any software, software design and software
     licensing referred to in the foregoing clause


                Amendment No. 1 to Capital Subscription Agreement

   14
          (iv) shall be the amount thereof determined in good faith as being
     properly allocable to the Borrower and its Subsidiaries as set forth in the
     officers' certificate referred to in said clause (iv).

     1.02. New Equity Contributions. Section 2(c) of the Capital Subscription
Agreement is hereby amended to read in its entirety as follows:

          "(c) New Equity Contributions. The Parent Equity Holders shall make
     additional Equity Contributions to the Parent, by remitting the same in
     U.S. Dollars and in immediately available funds to the Equity Contribution
     Account or, alternatively, by contributing equipment as permitted by clause
     (iii) of the definition of "Equity Contribution" in Section 1 (all such
     additional Equity Contributions to the Parent being herein referred to as
     the "New Equity Contributions"), from time to time as herein provided, to
     the extent necessary so that the aggregate amount of (x) the Pre-Closing
     Equity Contributions, plus (y) the New Equity Contributions, so made in the
     Parent on or before the dates set forth below shall each be equal to or
     greater than the respective amounts set forth below beside such dates (as
     such amounts shall be adjusted in accordance with the proviso set forth
     below):
