NOTE 1--BASIS OF PRESENTATION
 
    The condensed consolidated interim financial statements of Nextel
International, Inc. and subsidiaries ("Nextel International" or the "Company")
included herein have been prepared by the Company without audit, pursuant to the
rules and regulations of the Securities and Exchange Commission (the
"Commission") and reflect all adjustments that are, in the opinion of
management, necessary for a fair statement of the results for the interim
periods. All adjustments made were normal recurring accruals.
 
    The interim financial statements should be read in conjunction with the
consolidated financial statements and notes thereto included in the Company's
Exchange Offer Registration Statement on Form S-4 (Registration No. 333-26649),
as amended, which was declared effective by the Commission on August 8, 1997.
Operating results for the interim periods are not necessarily indicative of
results for an entire year.
 
    The accounts of the Company's foreign subsidiaries are consolidated as of a
date one month earlier than the accounts of the Company and its U.S.
subsidiaries to ensure timely reporting of consolidated results.
 
    Certain prior period amounts have been reclassified to conform with the
current presentation.
 
NOTE 2--SIGNIFICANT TRANSACTIONS
 
    MCCAW BRAZIL: On January 30, 1997, the Company's parent, Nextel
Communications, Inc. ("NCI"), purchased 81% of the issued and outstanding
capital stock of Wireless Ventures of Brazil, Inc. ("WVB") from Telcom Ventures,
Inc. and affiliates (collectively "Telcom Ventures") in exchange for $186.3
million in NCI Class A Common Stock ("NCI Common Stock"). NCI's investment in
WVB was simultaneously contributed to the Company, and the Company changed WVB's
name to McCaw International (Brazil), Ltd. ("McCaw Brazil"). McCaw Brazil and
its subsidiaries hold or have options to acquire licenses for 1,700 channels,
and provide specialized mobile radio ("SMR") services in 23 cities in Brazil
including Sao Paulo, Rio de Janeiro, Belo Horizonte, Curitiba, and Brasilia.
Telcom Ventures has the right between October 31, 2001 and November 1, 2003, to
require the Company to redeem their 19% interest in McCaw Brazil at fair market
value as determined pursuant to an appraisal procedure. The Company is currently
required to fund 100% of McCaw Brazil's capital requirements until April 30,
1999 when Telcom Ventures must either (i) contribute its pro rata share plus
accrued interest or (ii) dilute its ownership interest. Dividends are declared
at the discretion of McCaw Brazil's board of directors and are allocated based
on the ownership percentages in effect at the date of declaration. No dividends
have been declared to date.
 
    The total cost of the acquisition, which was accounted for as a purchase,
was $187.2 million and exceeded the net liabilities of McCaw Brazil by $215.7
million, which was allocated to licenses and goodwill based on their preliminary
estimated fair values and is being amortized over their estimated useful lives
of 20 years.
 
    Immediately prior to and in connection with the purchase of 49% of the
capital stock of MCS Radio Telefonia Ltda. (described below), the Company
reorganized its Brazil equity holdings so that AirLink S.A. ("AirLink," formerly
known as AirLink Servicos e Comercio, Ltda.), a wholly owned subsidiary of McCaw
Brazil, became a holding company for McCaw Brazil's Brazilian SMR licensee
companies. McCaw Brazil and subsidiaries other than AirLink continue to hold
options to acquire SMR licensees. The Company

NOTE 2--SIGNIFICANT TRANSACTIONS (CONTINUED)
intends to transfer any equity interest in SMR licensees obtained as a result of
the exercise of such options to AirLink.
 
    MCS: On September 26, 1997, AirLink acquired 49% of the capital stock of MCS
Radio Telefonia, Ltda. ("MCS"), an indirect wholly owned subsidiary of Motorola,
Inc. ("Motorola"), an option to purchase the remaining 51% of the capital stock
of MCS upon receipt of the approval of the applicable Brazilian regulatory
authorities, and certain assets of MCS. Upon the approval of the Brazilian
regulatory authorities, the option for the remaining 51% will be exercisable for
approximately $3.2 million. In exchange, Motorola, through a wholly owned
subsidiary, acquired 5% of the outstanding capital stock of AirLink. MCS owns
SMR licenses in thirteen of the largest Brazilian cities, including Sao Paulo,
Rio de Janeiro and Belo Horizonte. Immediately subsequent to the acquisition,
the Company, through its 81% equity interest in McCaw Brazil and McCaw Brazil's
95% equity interest in AirLink, held a 77% equity interest in AirLink.
 
    The total cost of the acquisition, which was accounted for as a purchase,
was $20.2 million and exceeded the book value of the net tangible assets of MCS
by $16.7 million. The excess was allocated to licenses and goodwill based on
their preliminary estimated fair values and will be amortized over their
estimated useful lives of 20 years.
 
    MOBILCOM: In January 1997, NCI purchased additional common shares of
Corporacion Mobilcom S.A. de C.V., a Mexican SMR operator ("Mobilcom") at a cost
of $16.5 million, in exchange for shares of NCI Common Stock. Such interest was
simultaneously contributed to the Company. In February 1997, Mobilcom
shareholders approved a $27.0 million capital call (the "Mobilcom Capital
Call"), and the Company funded its pro rata share (approximately $10.3 million)
with a cash contribution. On April 16, 1997, the Company purchased additional
shares of Mobilcom by funding the unsubscribed portion of the Mobilcom Capital
Call (approximately $11.1 million), thereby increasing the Company's ownership
interest to approximately 46.3%.
 
    Through a series of transactions from June 30, 1997 to August 31, 1997, the
Company acquired additional shares of Mobilcom from shareholders that held a
right to put (the "Mobilcom Put") the entire amount of their holding to the
Company at its appraised fair market value. The transactions were consummated at
an aggregate cost of $57.1 million and increased the Company's equity interest
in Mobilcom to approximately 76.5%. Approximately $22.1 million of the purchase
price is payable in January 1998 and is included in accounts payable, accrued
expenses and other as of September 30, 1997. As a result of such acquisitions,
the Company is no longer subject to the rights formerly held by the Mobilcom Put
holders.
 
    As the Mobilcom acquisitions resulted in the Company owning greater than 50%
of the outstanding common stock and obtaining control of Mobilcom, the Company
consolidated the accounts of Mobilcom commencing on September 1, 1997 under the
purchase method of accounting. The carrying amount of the Company's investment
in Mobilcom as of August 31, 1997 totaled approximately $152.3 million and
exceeded the book value of the net tangible assets of Mobilcom by $107.8
million. The excess was allocated to licenses and goodwill based on their
preliminary estimated fair values and is being amortized over their estimated
useful lives of 20 years.

NOTE 2--SIGNIFICANT TRANSACTIONS (CONTINUED)
    MCCAW ARGENTINA: On May 6, 1997, the Company contributed its 100% ownership
interest in McCaw Argentina S.A. ("MCASA") into Nextel International
(Argentina), Ltd. ("Nextel Argentina") (formerly McCaw International
(Argentina), Ltd.), a joint venture between the Company and Wireless Ventures of
Argentina, L.L.C. ("WVA"). WVA's contribution included all of the outstanding
common stock of a paging company and two companies that own SMR licenses in
Argentina. The Company has a 50% voting interest and shares equally in the
profits and losses of the joint venture. Capital contributions are to be made
equally unless otherwise agreed to by both the Company and WVA. Commencing on
May 6, 1997, the Company is accounting for its investment in the joint venture
under the equity method of accounting. Prior to May 6, 1997, the Company's
consolidated financial statements included selling, general and administrative
expenses related to MCASA totaling $772 and $1,668 for the nine months ended
September 30, 1997 and 1996, respectively and $1,253 for the three months ended
September 30, 1996. Other results of operations related to MCASA were
insignificant.
 
    INDONESIA: On August 15, 1997 the Company entered into an agreement to form
a joint venture with PT Gunung Sewu Kencana, a large diversified Indonesian
corporation ("GSK"), using PT Mitra Kencana Telekomunindo, an Indonesian
corporation owned by GSK ("MKT"), as the joint venture company. MKT holds a
provisional license for 80 SMR channels that can be converted by MKT, upon
satisfaction of certain regulatory requirements, into an operating license
whereby MKT will be entitled to provide SMR and ESMR services in the city of
Jakarta and the regions of West Java, East Java and Bandar Lampung. Upon such
deployment of services in accordance with the operating license, MKT will have
the right to continue developing a national wireless communications network
across Indonesia and providing SMR and ESMR services on a nationwide basis.
 
    Upon receiving the required regulatory approval to become a shareholder of
MKT ("Ministry Approval"), which is expected to occur by March 31, 1998, the
Company is expected to acquire an equity interest in MKT representing 37.5% of
the outstanding stock of MKT. Notwithstanding its 37.5% equity interest in MKT,
the Company has agreed to fund 44% (rather than 37.5%) of the capital
requirements of MKT in order to maintain its then-current ownership interest.
Profits and losses are to be allocated and dividends are to be distributed based
on the Company's 37.5% equity interest.
 
    The Company has committed to loan MKT sufficient funds to meet 44% of the
interim cash needs of MKT in advance of the receipt of Ministry Approval (the
aggregate of such advances, the "MKT Loan"). The Company's share of such funds
is currently estimated to be approximately $16 million through March 31, 1998.
The Company is not obligated to provide funds to MKT after March 31, 1998 if
Ministry Approval has not been obtained by such date. The MKT Loan is guaranteed
by GSK. No amounts have been advanced to MKT through September 30, 1997.
 
    Upon receipt of Ministry Approval, the MKT Loan will be converted to equity
and applied to the Company's initial capital contribution. If the Company does
not receive Ministry Approval by March 31, 1998, the MKT Loan will be payable on
demand together with interest accruing as of the date of demand. No interest
will be payable on the MKT Loan if the Company converts such loan into an equity
interest in MKT. Upon conversion of the MKT Loan into equity, the MKT Loan will
be extinguished and the Company will account for its investment in MKT under the
equity method of accounting.
 
    SHANGHAI CCT MCCAW: In October 1997, a subsidiary of CCT Telecom Holdings
Limited, a publicly traded Hong Kong telecommunications company, acquired a 51%

Telecommunications Co. Ltd., the Chinese joint venture in which the company
maintained a 60% ownership interest, in exchange for approximately $46 million
of capital contributions, access fees, loans and lease guarantees. Immediately
thereafter, the joint venture's name was changed to Shanghai CCT -  McCaw
Telecommunications System Co., Ltd. ("Shanghai CCT McCaw"). The acquisition,
which was made directly from Shanghai CCT McCaw, diluted the Company's ownership
interest in Shanghai CCT McCaw to 30% and its contractual right to the profits
generated by a Global System for Mobile communications ("GSM") network in
Shanghai, China to approximately 12.1%. As the Company's investment in Shanghai
CCT McCaw is accounted for under the cost method, the transaction is not
expected to have a significant effect on the Company's consolidated financial
statements.

NOTE 3--INVESTMENT IN UNCONSOLIDATED SUBSIDIARIES
 
    Investments where the Company has the ability to exercise significant
influence over operating and financial policies and possesses a voting interest
of 50% or less are accounted for under the equity method. The Company's equity
in net loss of Mobilcom, its only significant equity investment, was $519 and
$1,269 for the three months ended September 30, 1997 and 1996, and $3,255 and
$3,808 for the nine months ended September 30, 1997 and 1996, respectively. The
Company's equity in net loss of Mobilcom differs from its proportionate share of
its reported net income primarily due to the amortization of the excess purchase
price over net assets acquired. Commencing September 1, 1997, the Company

NOTE 4--COMPANY FINANCING
 
    LONG-TERM DEBT: In March 1997, the Company completed a private placement of
951,463 units yielding approximately $482.0 million in net proceeds. Each unit
is comprised of a 10-year senior discount note (with a principal amount at
maturity of $1,000) and a detachable warrant to purchase 0.38748 shares of the
Company's common stock. The notes have a 13% yield to maturity, are noncallable
for five years, and require no interest payments for the first five years. The
warrants are exercisable at a price of $9.99 per share and entitle the holders
to purchase, in the aggregate, approximately 368,673 shares of the Company's
common stock.
 
    PHILIPPINES FINANCING: In June 1997, Infocom Communication Network, Inc.
("Infocom") and Motorola, Inc. ("Motorola") entered into an equipment financing
agreement (the "Philippines Motorola Financing"), pursuant to which Motorola
agreed to provide up to $15 million in term loans to Infocom to finance the
purchase of infrastructure equipment and services from Motorola. The terms of
the Philippines Motorola Financing provides for a maturity of two years and an
annual interest rate of LIBOR plus 506 basis points. Pursuant to the Philippines
Motorola Financing the term loans are secured by a first-priority lien on
substantially all of Infocom's assets and a pro rata guarantee of such financing
by each of Infocom's shareholders, including the Company.
 
    BRAZIL FINANCING: In October 1997, McCaw Brazil and Motorola Credit Corp., a
subsidiary of Motorola ("Motorola Credit"), entered into an Equipment Financing
Agreement whereby Motorola Credit agreed to provide up to $125 million in
revolving loans (the "Brazil Motorola Financing") to McCaw Brazil to be used to
acquire infrastructure equipment and related services from Motorola. The Brazil
Motorola Financing is repayable in semi-annual installments over a period of 42
months commencing June 30, 2000 and bears interest at an annual rate
periodically determined by the Company of either the LIBOR rate plus 463 basis
points or the prime rate plus 250 basis points. Pursuant to the Brazil Motorola
Financing, the revolving loans are secured by a first priority lien on
substantially all of McCaw Brazil's assets, a pledge of all of the stock of
McCaw Brazil and its subsidiaries, including AirLink, and guarantees by the
Company and Motorola International Development Corporation (which indirectly
holds a 5% equity interest in AirLink) of 93.9% and 6.1%, respectively, of McCaw
Brazil's obligations under such financing. Additionally, approximately $70.3
million of the Company's cash, cash equivalents and marketable securities have
been restricted for use as future equity investments in McCaw Brazil and its
subsidiaries.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS.
 
OVERVIEW.
 
    The following is a discussion of the condensed consolidated financial
condition and results of operations of Nextel International, Inc. ("Nextel
International" or the "Company"), an indirectly wholly owned subsidiary of
Nextel Communications, Inc. ("Nextel Communications"), for the nine month
periods ended September 30, 1997 and 1996.
 
    The Company currently provides wireless communications services in the four
largest cities in Latin America and two of the largest cities in Asia, primarily
utilizing specialized mobile radio ("SMR") channels in its licensed service
areas. The wireless services companies in which the Company holds interests
operate in markets covering approximately 230 million people, approximately 120
million of which are in Latin America. Nextel International, through its
operating subsidiaries, is the largest SMR service provider in Brazil and
Mexico, and holds the largest SMR channel position in Argentina.
 
    The Company's strategy is to focus on leveraging its analog dispatch or SMR
channel positions in its principal markets and using Nextel Communication's
experience and supplier relationships to upgrade its services from analog
dispatch to digital enhanced specialized mobile services ("ESMR"). The upgrade
to digital networks will allow the Company to increase capacity significantly
and to offer additional services and features such as enhanced dispatch (group
calling and instant conferencing), high-quality telephone interconnect and text
messaging. The Company is upgrading its analog SMR networks to digital ESMR
networks using the integrated Digital Enhanced Network ("iDEN") technology
developed by Motorola, Inc. ("Motorola") and deployed by Nextel Communications
in certain of its markets. The Company also continues to assess additional
opportunities to enter into new markets, particularly in Latin America and Asia.
 
    The Company owns interests in and actively participates in the management of
wireless communications services companies in Brazil, Argentina, Mexico and the
Philippines. In addition, the Company currently has a contractual right through
its Chinese joint venture to receive approximately 12.1% of the profits
generated by a Global System for Mobile communications ("GSM") network in
Shanghai, China (the "Shanghai GSM System") and has a 3.7% interest in Clearnet
Communications Inc., a Canadian wireless communications services company. The
wireless services companies in which the Company holds interests or a
contractual right are referred to herein as the "Operating Companies."
Additionally, upon formation of the Indonesian joint venture company, the
Company will hold a 37.5% equity interest in an SMR operator in Indonesia.
 
    Immediately prior to and in connection with the purchase of 49% of the
capital stock of MCS Radio Telefonia Ltda. (described below), the Company
reorganized its Brazil equity holdings so that AirLink S.A. ("AirLink," formerly
known as AirLink Servicos e Comercio, Ltda.), a wholly owned subsidiary of McCaw
International (Brazil), Ltd. ("McCaw Brazil"), became a holding company for
McCaw Brazil's SMR Brazilian licensee companies. McCaw Brazil and subsidiaries
other than AirLink continue to hold options to acquire SMR licensees. The
Company intends to transfer any equity interest in SMR licensees obtained as a
result of the exercise of such options to AirLink.
 
    On September 26, 1997, AirLink acquired 49% of the capital stock of MCS
Radio Telefonia, Ltda. ("MCS"), an indirect wholly owned subsidiary of Motorola,
Inc. ("Motorola"), an option to purchase the remaining 51% of the capital stock
of MCS upon receipt of the approval of the applicable Brazilian regulatory
authorities, and certain assets of MCS. Upon the approval of the Brazilian
regulatory authorities, the option for the remaining 51% will be exercisable for
approximately $3.2 million. In exchange, Motorola, through a wholly owned
subsidiary, acquired 5% of the outstanding capital stock of AirLink. MCS owns
SMR licenses in thirteen of the largest Brazilian cities, including Sao Paulo,
Rio de Janeiro and Belo Horizonte. Immediately subsequent to the acquisition,
the Company, through its 81% equity interest
 
                                       14
<PAGE>
in McCaw Brazil and McCaw Brazil's 95% equity interest in AirLink, held a 77%
equity interest in AirLink.
 
POST FISCAL QUARTER-END TRANSACTIONS AND DEVELOPMENTS
 
    SHANGHAI.  In October 1997, a subsidiary of CCT Telecom Holdings Limited, a
publicly traded Hong Kong telecommunications company, acquired a 51% ownership
interest in Shanghai McCaw Telecommunications Co. Ltd., the Chinese joint
venture in which the company maintained a 60% ownership interest, in exchange
for approximately $46 million of capital contributions, access fees, loans and
lease guarantees. Immediately thereafter, the joint venture's name was changed
to Shanghai CCT - McCaw Telecommunications System Co., Ltd. ("Shanghai CCT
McCaw"). The acquisition, which was made directly from Shanghai CCT McCaw,
diluted the Company's ownership interest in Shanghai CCT McCaw to 30% and the
Company's contractual rights to the profits generated by the Shanghai GSM System
to approximately 12.1%.
 
    BRAZIL.  In October 1997, McCaw Brazil and Motorola Credit Corp., a
subsidiary of Motorola ("Motorola Credit"), entered into an Equipment Financing
Agreement whereby Motorola Credit agreed to provide up to $125 million in
revolving loans (the "Brazil Motorola Financing") to McCaw Brazil to be used to
acquire infrastructure equipment and related services from Motorola. The Brazil
Motorola Financing is repayable in semi-annual installments over a period of 42
months commencing June 30, 2000 and bears interest at an annual rate
periodically determined by the Company of either the LIBOR rate plus 463 basis
points or the prime rate plus 250 basis points. Pursuant to the Brazil Motorola
Financing, the revolving loans are secured by a first priority lien on
substantially all of McCaw Brazil's assets, a pledge of all of the stock of
McCaw Brazil and its subsidiaries, including AirLink, and a guarantee by the
Company and Motorola International Development Corporation (which indirectly
holds a 5% equity interest in AirLink) of 93.9% and 6.1%, respectively, of McCaw
Brazil's obligations under such financing. Additionally, approximately $70.3
million of the Company's cash, cash equivalents and marketable securities have
been restricted for use as future equity investments in McCaw Brazil and its
subsidiaries.
 
    BRAZIL REGULATIONS.  On November 3, 1997, the Ministry of Communications of
Brazil (the "Brazil Ministry of Communications") issued Ordinance 557, which
adopted Norma 14/97 ("Norma 14/97"). Norma 14/97 enacts the proposed regulations
that were published for comment in May 1997 and June 1997, and repeals Brazil
Ministry of Communications Administrative Ruling No. 478, each of which was
described in the Company's Exchange Offer Registration Statement on Form S-4
(Registration No. 333-26649), as amended, substantially as proposed. Norma 14/97
provides the regulations governing SMR providers in Brazil, including service
requirements, interconnection rules, license consolidation and transfer of
licenses and technical specifications.
 
    SMR SERVICES.  Norma 14/97 provides that SMR service may only be provided to
legal entities or groups of legal entities for the performance of specific
activities. SMR service may not be provided to individual subscribers, and all
SMR subscriber units must be capable of providing dispatch service.
 
    INTERCONNECTION RULES.  Norma 14/97 prohibits an operator of a public
switched telecommunications network ("PSTN") from adopting practices that
inhibit competition or procedures that result in discrimination of any kind
against SMR licenseholders. Norma 14/97 contemplates that each SMR provider will
obtain interconnection to the PSTN pursuant to interconnection agreements with
the operators of the PSTN. If interconnection negotiations do not produce an
interconnection agreement within 60 days of the commencement of negotiations or
if full interconnection is not implemented within 90 days of the conclusion of
negotiations, either party to the negotiation may refer the matter to the Brazil
Ministry of Communications for resolution.
 
    Under Norma 14/97, an SMR service provider must apply to the Brazil Ministry
of Communications to obtain blocks of telephone numbers to be used by such SMR
service provider for use by its subscribers.
 
                                       15
<PAGE>
The telephone numbers granted by the Brazil Ministry of Communications cannot
exceed 50% of the total number of SMR mobile subscriber units projected to be in
operation by the SMR service provider, as projected by the SMR service provider
in the schedule for the deployment of the services.
 
    Norma 14/97 also limits the volume of interconnect traffic for SMR service
providers. Norma 14/97 provides that within an SMR service provider's network,
the volume of traffic interconnected with the PSTN cannot exceed one third of
the sum of intra-network traffic volume and outgoing calls interconnected to the
PSTN. For purposes of calculating the number of intra-network calls, each
subscriber unit called during a one-to-many dispatch call counts as one
intra-network call. The evaluation of the traffic volumes for the purposes of
the above restrictions is to take place every four months.
 
    LICENSE CONSOLIDATION AND TRANSFER OF LICENSES.  Norma 14/97 provides that
SMR licenseholders may not hold more than 200 SMR channels (10 MHz) in each
geographic area. Under Norma 14/97, the transfer of a license or the controlling
interest of a licensee may only be effected after the actual commencement of
commercial operation of service. Norma 14/97 permits SMR licensees that are
under common ownership or control to request the Brazil Ministry of
Communications to consolidate their SMR licenses, subject to the 200 channel
limitation, under one SMR licensee. The Brazil Ministry of Communications must
approve any request for consolidation within three months of receipt of such
request.
 
    Although the Company believes that the current regulatory framework, as
embodied by Norma 14/97, permits the Company's current and planned operations in
Brazil, there can be no assurance that the Brazilian government or the Brazil
Ministry of Communications will not modify the existing regulatory framework in
a manner that is materially adverse to the Company. Additionally, because the
Brazilian telecommunications regulatory framework, including SMR, is relatively
new and still developing and the enforcement of regulations is often uncertain,
it is difficult to determine how regulators will interpret the rules or judge
compliance. Any actions by the Brazilian government or the Brazil Ministry of
Communications impeding or placing substantial restrictions on the Company's
ability to deploy ESMR services could have a material adverse effect on the
Company's competitive position in Brazil and on its business and results of
operations.
 
RESULTS OF OPERATIONS
 
NINE MONTHS ENDED SEPTEMBER 30, 1997 VS. NINE MONTHS ENDED SEPTEMBER 30, 1996
 
    The Company acquired majority interests in McCaw International (Brazil),
Ltd. ("McCaw Brazil") and Corporacion Mobilcom S.A. de C.V. ("Mobilcom") in
January 1997 and August 1997, respectively. Accordingly, there were no
comparable revenues or costs and expenses related to revenues in the nine months
ended September 30, 1996. For the first nine months of 1997, substantially all
of the revenues and costs and expenses related to revenues result from the eight
months of McCaw Brazil's SMR operations and one month of Mobilcom's SMR
operations included in the Company's consolidated financial statements.
 
    Selling, general and administrative expenses increased $11.3 million to
$17.6 million for the nine months ended September 30, 1997 from $6.3 million for
the nine months ended September 30, 1996. The increase is primarily attributable
to $12.2 million of expenses from the McCaw Brazil operations which have been
included in the Company's consolidated results of operations commencing January
1997.
 
    Depreciation and amortization expense totaled $11.3 million for the nine
months ended September 30, 1997. The amount is primarily attributable to
depreciation and amortization expense of approximately $9.9 million related to
McCaw Brazil. The remaining amount is due to depreciation and amortization
expenses related to Mobilcom and the amortization of licenses in Argentina which
commenced commercial operations in February 1997. No significant depreciation
and amortization expense was recognized during the nine months ended September
30, 1996.

    Interest income increased $11.6 million to $15.0 million for the nine months
ended September 30, 1997 from $3.4 million for the nine months ended September
30, 1996. The increase was primarily attributable to income recognized on the
investment of the net proceeds from the Company's issuance in March 1997 of
units consisting of senior discount notes due 2007 and detachable warrants to
purchase up to 1% of the Company's outstanding common stock (the "Units
Issuance"). See--"Liquidity and Capital Resources."
 
    Interest expense of $39.1 million was recognized during the nine months
ended September 30, 1997 of which $38.2 million represented interest accretion
on the long-term debt associated with the Units Issuance and amortization of
associated debt issue costs. Additionally, Nextel International (CANMEX), Ltd.
("Canmex") (formerly McCaw International (CANMEX), Ltd.), a wholly owned
subsidiary of the Company incurred $0.4 million of interest expense on a note
payable to the Company's parent, and McCaw Brazil and Mobilcom incurred
approximately $0.5 million of interest expense on short term borrowings. During
the nine months ended September 30, 1997, the Company capitalized $0.5 million
of interest expense in connection with the construction and development of its
digital ESMR networks. No interest expense was incurred during the nine months
ended September 30, 1996.
 
    Loss from equity method investments increased $2.3 million to $6.3 million
for the nine months ended September 30, 1997 from $4.0 million for the nine
months ended September 30, 1996. The increase was primarily attributable to
approximately $2.4 million in losses associated with the Company's investment in
Nextel International (Argentina), Ltd. ("Nextel Argentina") (formerly McCaw
International (Argentina), Ltd.), which has been accounted for under the equity
method since May 1997.
 
    Minority interest in the net loss of McCaw Brazil and Mobilcom totaled $2.3
million during the nine months ended September 30, 1997. The amount is primarily
attributable to the minority shareholder's interest in McCaw Brazil subsequent
to the acquisition of an 81% interest by the Company in January 1997.
 
    The Company recognized an income tax benefit of $3.4 million during the nine
months ended September 30, 1997 compared to an income tax provision of $1.1
million during the nine months ended September 30, 1996. The income tax benefit
recognized during the nine months ended September 30, 1997 was primarily
attributable to net operating losses of Brazil allowed to be recognized due to
the existence of Brazilian taxable temporary differences. The income tax expense
recognized for the nine months ended September 30, 1996 was primarily
attributable to the taxes associated with Canmex's interest income.
 
THREE MONTHS ENDED SEPTEMBER 30, 1997 VS. THREE MONTHS ENDED SEPTEMBER 30, 1996
 
    The Company acquired majority interests in McCaw Brazil and Mobilcom in
January 1997 and August 1997, respectively. Accordingly, there were no revenues
or costs and expenses related to revenues in the three months ended September
30, 1996. For the third quarter of 1997, a majority of the revenues and costs
and expenses related to revenues result from McCaw Brazil's SMR operations
included in the Company's consolidated financial statements. Revenues and costs
and expenses related to revenues attributable to the one month of Mobilcom's SMR
operations included in the Company's consolidated financial statements totaled
$0.7 million and $0.2 million, respectively.
 
    Selling, general and administrative expenses increased $3.0 million to $7.4
million for the three months ended September 30, 1997 from $3.4 million for the
three months ended September 30, 1996. The increase is primarily attributable to
the expenses from the McCaw Brazil operations which have been included in the
Company's consolidated results of operations commencing January 1997.
 
    Depreciation and amortization expense totaled $4.7 million for the three
months ended September 30, 1997. The amount is primarily attributable to
depreciation and amortization expense of approximately $3.7 million related to
McCaw Brazil. The remaining amount is due primarily to depreciation and
 
                                       17
<PAGE>
amortization expenses related to Mobilcom. No significant depreciation and
amortization expense was recognized during the three months ended September 30,
1996.
 
    Interest income increased $5.2 million to $6.1 million for the three months
ended September 30, 1997 from $0.9 million for the three months ended September
30, 1996. The increase was primarily attributable to income recognized on the
investment of the proceeds from the Units Issuance.
 
    Interest expense of $16.8 million was recognized during the three months
ended September 30, 1997 of which $16.7 million represented accretion on the
long-term debt associated with the Units Issuance and amortization of debt issue
costs. During the three months ended September 30, 1997, the Company capitalized
$0.5 million of interest expense associated with the construction and
development of its digital ESMR networks. No interest expense was recognized
during the three months ended September 30, 1996.
 
    Loss from equity method investments increased $0.9 million to $2.4 million
for the three months ended September 30, 1997 from $1.5 million for the three
months ended September 30, 1996. The increase was primarily attributable to
losses associated with the Company's investment in Nextel Argentina, which has
been accounted for under the equity method since May 6, 1997.
 
    Minority interest in the net loss of McCaw Brazil and Mobilcom totaled $0.9
million during the three months ended September 30, 1997. The amount is
primarily attributable to the minority shareholder's interest in McCaw Brazil
subsequent to the acquisition of an 81% interest in McCaw Brazil by the Company
on January 30, 1997.
 
    The Company recognized an income tax benefit of $1.3 million during the
three months ended September 30, 1997 compared to an income tax provision of
$0.3 million during the three months ended September 30, 1996. The income tax
benefit recognized during the three months ended September 30, 1997 was
primarily attributable to net operating losses of Brazil allowed to be
recognized due to the existence of Brazilian taxable temporary differences. The
income tax expense recognized for the three months ended September 30, 1996 was
primarily attributable to the taxes associated with Canmex's interest income.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has incurred historical net losses of approximately $77.5
million since inception through September 30, 1997. The Company expects to
continue to incur increasing losses and negative operating cash flows as it
continues to build-out and upgrade its existing wireless communications
networks.
 
    Net cash provided by operating activities for the nine months ended
September 30, 1997 was approximately $2.2 million. Net cash used by investing
activities for the nine months ended September 30, 1997 was approximately $226.0
million. Net cash provided by financing activities for the nine months ended
September 30, 1997 was approximately $465.2 million. Working capital as of
September 30, 1997 increased to $334.1 million compared to a negative $98.3
million at December 31, 1996. The cash used by investing activities primarily
represented investments in the Operating Companies to fund the build-out of the
Company's ESMR networks and acquire additional equity ownership interests. The
cash provided by financing activities and the increase in working capital are
primarily a result of the Company receiving approximately $482.0 million of net
proceeds from the Units Issuance. As a result of the above activities, cash and
cash equivalents increased approximately $241.4 million during the nine months
ended September 30, 1997.
 
    Through March 3, 1997, funds necessary to finance the Company's activities
were provided to the Company primarily by its parent company (which is an
unrestricted subsidiary of Nextel Communications), in the form of equity
contributions. The Company's parent company is not obligated to provide any
additional funding to the Company. For the next several years, the Company
anticipates using its existing cash and investments and externally generated
funds from debt and equity sources as discussed below to cover future needs,
including the design, implementation and operation of the Company's ESMR
networks
 
                                       18
<PAGE>
and the acquisition of additional equity interests in the Operating Companies.
Additionally, the Company is considering expanding its operations into other
markets through investments in unaffiliated companies.
 
    In November 1996, Nextel, Nextel International and Motorola entered into a
binding memorandum of understanding (the "Motorola MOU") regarding the terms of
financing to be provided by Motorola to fund the purchase of Motorola equipment
by the Operating Companies other than Clearnet (the "Motorola Financing"). Under
the Motorola MOU, the significant terms of which are more fully described in the
Company's Exchange Offer Registration Statement on Form S-4, as amended
(Registration No. 333-26649), Motorola agreed to provide an aggregate of up to
$400 million in vendor financing to Nextel Communications and Nextel
International for the worldwide purchase of iDEN equipment and services and
ancillary products (such as switches). In March 1997, Motorola and Nextel
entered into an agreement increasing the maximum worldwide vendor financing
available to Nextel and Nextel International to $650 million, with a maximum
non-U.S. amount outstanding of $400 million, subject to certain per country
limits as agreed to in the Motorola MOU. The terms of any borrowings under the
Motorola Financing are subject to negotiation and execution of definitive
agreements. The availability of borrowings pursuant to the Motorola Financing
are expected to be subject to certain conditions, and there can be no assurance
that such conditions will be met. In July 1997, in accordance with the Motorola
MOU, Infocom and Motorola entered into an equipment financing agreement (the
"Philippines Motorola Financing"), pursuant to which Motorola will provide up to
$15 million of vendor financing in the form of term loans to Infocom.
Additionally, in October 1997, McCaw Brazil and Motorola Credit entered into the
Brazil Motorola Financing, pursuant to which Motorola Credit will provide up to
$125 million of vendor financing in the form of revolving loans to McCaw Brazil.
 
    Any amounts available to be borrowed by the Operating Companies under the
Motorola Financing will be reduced by any amounts borrowed by Nextel and its
subsidiaries other than the Company and the Operating Companies. Nextel has
committed to the Company that at least $95 million of the Motorola Financing
will be available to the Company. As of September 30, 1997, Nextel had borrowed
$151 million pursuant to the Motorola Financing. In addition, to the extent
total amounts outstanding under the Motorola Financing to Nextel and its
subsidiaries, including the Company and the Operating Companies (other than
Clearnet), plus requests for additional financing under the Motorola Financing
by Nextel and its subsidiaries other than the Company and the Operating
Companies would exceed $400 million, Nextel International is required to repay
or cause to be repaid sufficient borrowings such that after giving effect to
such repayment, the total amount of loans outstanding from Motorola to Nextel
and its subsidiaries, including the Company and the Operating Companies (other
than Clearnet), will not exceed $400 million (any such repayment is referred to
as a "Forced Repayment"). Nextel has agreed with the Company not to cause a
Forced Repayment.
 
    The Company expects approximately $220 million of the funds necessary to
design, implement and operate the Company's planned ESMR networks will be
obtained at the Operating Company level through the Motorola Financing and other
project financing sources. Based on the Motorola Financing agreements entered
into to date between Motorola and the Operating Companies and preliminary
discussions with other project financing sources, the Company believes that it
will be able to obtain sufficient financing to meet its current objectives for
funding at the Operating Company level. There can be no assurance that the
Company will be able to raise such capital on satisfactory terms, if at all. See
"--Forward Looking Statements."
 
    The Company believes that its current available cash and cash equivalents,
together with borrowings expected to be available under existing and proposed
project financing, including the Motorola Financing, will be sufficient to fund
the cash needs of the Company's current operations, including the planned
expansion of its existing operations, but excluding any additional investments
or acquisitions, through the end of fiscal year 1999. Thereafter, the Company
may require substantial additional capital. If the Company's plans or
assumptions change, if its assumptions prove to be inaccurate, if it consummates
additional investments or acquisitions, if it experiences unanticipated costs or
competitive pressures, or if
 
                                       19
<PAGE>
the Company's available cash and cash equivalents, together with the proceeds of
any borrowings under the Motorola Financing or other project financing sources
identified above, otherwise prove to be insufficient or cannot be obtained at
satisfactory terms, if at all, the Company may be required to seek additional
capital sooner than currently anticipated. See "--Forward-Looking Statements."
 
    In the future, the Company may consider obtaining financing from various
other sources, including capital contributions from Nextel Communications in the
form of cash or Nextel Communications common stock, vendor financing provided by
equipment suppliers, project financing from commercial banks and international
agencies such as International Finance Corporation and Overseas Private
Investment Corporation, bank lines of credit and sales of equity and debt issued
by the Operating Companies and/or the Company. Nextel Communications has no
obligation to provide any such financing and to the extent the Company issues
debt, its leverage and debt service obligations will increase. There can be no
assurance that the Company will be able to raise such capital on satisfactory
terms, if at all. See "--Forward-Looking Statements."

    principal amount equal to the Maximum Total Foreign Advance Excess;

           (iv)   on the dates and the amounts specified in subsection 2.06(b)
    and Sections 2.09 or 2.10 hereof if the Company shall be required to prepay
    the Advances pursuant to such Sections; and

            (v)   if any Affiliated Company makes a payment to the Creditor or
    any other Motorola Entity pursuant to the Vendor Financing Agreement or any
    other agreement in effect between any Motorola Entity and any of the
    Affiliated Companies that relates to the iDEN equipment and services, then
    during the Availability Period, the Company may reborrow an amount equal to
    the least of (i) the aggregate amount prepaid by the Company pursuant to
    subsections 2.05(a)(ii) and (iii) hereof, (ii) the amounts so paid by the
    Affiliated Companies, (iii) an amount which will cause the aggregate

                                      29

<PAGE>

    Advance Amount to equal $650,000,000, and (iv) an amount which will cause
    the aggregate Outstanding Foreign Advance Amount to equal $400,000,000.

       (b)  OPTIONAL PREPAYMENT.

            The Company may prepay Advances, in whole or in part, in integral 
multiples of $100,000 upon not less than thirty (30) days prior written 
notice to the Creditor of the principal amount to be prepaid and the date of 
such prepayment.  On the date specified for prepayment, the Company shall pay 
such principal amount plus accrued interest on such principal amount prepaid 
to the date of such prepayment.  Notwithstanding the foregoing, unless the 
conditions set forth in subsection 2.05(c) hereof shall be simultaneously 
satisfied, LIBOR Advances may be only repaid on the last day of the Interest 
Period for such LIBOR Advance.  A notice of prepayment once received shall be 
irrevocable and binding on the Company.

       (c)  BROKEN FUNDING INDEMNIFICATION.

            The Company shall pay to the Creditor, such amount or amounts as 
shall compensate the Creditor for any loss, cost or expense incurred by the 
Creditor (as reasonably determined and documented by the Creditor) as a 
result of:

            (i)  any prepayment or repayment of a LIBOR Advance on a date other
    than the last day of the Interest Period for such LIBOR Advance; or

           (ii)  any failure by the Company to borrow a LIBOR Advance on the
    Drawdown Date specified in the relevant Request for Financing under Section
    2.02 hereof, such compensation to include, without limitation, an amount
    equal to: (x) any loss or expense suffered by the Creditor during the
    period from such failure to borrow to the last day of such Interest Period
    if the rate of interest obtainable by the Creditor upon the redeployment of
    an amount of funds equal to the amount not borrowed is less than the rate
    of interest applicable to such LIBOR Advance for such Interest Period or
    (y) any loss or expense suffered by the Creditor in liquidating LIBOR
    deposits prior to maturity.

            The Company shall pay any amount due hereunder no later than seven
    (7) days after receipt of an invoice therefor from the Creditor.

       (d)  EFFECT OF PREPAYMENT.

            All Advances prepaid, whether by mandatory or optional 
prepayment, may not be reborrowed (except as provided in subsection 
2.05(a)(v) hereof and amounts repaid pursuant to clause (i) of penultimate 
sentence of subsection 2.02(a) hereof) and the Commitment shall automatically 
be reduced by the amount of such prepayment.

       (e)  CERTAIN REIMBURSEMENTS IN RESPECT OF PREPAYMENTS.

                                      30
<PAGE>
         Without affecting the obligations of the Company set forth above, the
Creditor acknowledges that (i) the primary source of funds for the prepayments
described above will be revenue generated in Brazil by the operations of the
Foreign Affiliates and that the Company expects to make any required prepayments
from corresponding prepayment amounts which AirLink is obligated to make to the
Company under the Conditional Sale Agreements, and (ii) the transferring of the
amounts for such prepayments under the Conditional Sale Agreements will be
subject to the approval of the Central Bank in Brazil.  In the event that (i)
(x) the Company is prohibited by applicable law from maintaining a Foreign
Resident Account or (y) the use of such Foreign Resident Account would result in
a significant cost to the Company, and (ii) the approval of the Central Bank is
not obtained within the applicable periods provided for above (notwithstanding
the reasonable efforts of the Company and AirLink to obtain such approval),
Nextel International may make an intercompany loan to the Company in the amount
of such prepayment no later than 151 days after the end of such fiscal year. 
Simultaneously with the receipt of such intercompany loan, the Company shall use
the proceeds thereof to make the prepayment required pursuant to this Section
2.05.  After making such prepayment and so long as no Default shall have
occurred and is continuing under this Agreement, then such intercompany loan may
be repaid directly or indirectly to Nextel International by the Company or
AirLink pursuant to the terms of the Company Security Deposit Agreement and the
AirLink Security Deposit Agreement.

SECTION 2.06  INTEREST.

    (a)       The Company shall pay to the Creditor interest on the outstanding
principal amount of each Advance made by the Creditor, for the period commencing
on the date of such Advance until such Advance is paid in full, at the following
rate per annum:

         (i)    if such Advance is a Prime Advance, a rate per annum equal to
    the Prime Rate (as in effect from time to time) plus the Applicable Margin;
    and 

         (ii)   if such Advance is a LIBOR Advance, for each Interest Period
    relating thereto, the LIBOR Rate for such Advance plus the Applicable
    Margin.

    Accrued interest on each Advance shall be paid in arrears on the Interest
Payment Dates.  Notwithstanding the foregoing, Interest that is payable at the
Post-Default Rate shall be payable from time to time on demand of the Creditor.

    (b)       Anything herein to the contrary notwithstanding, if, on or prior
to the determination of an interest rate for any LIBOR Advance for any Interest
Period therefor, the Creditor reasonably determines (which determination shall
be conclusive absent manifest error):

         (i)       by reason of any event affecting the money markets in the
    United States of America or the London interbank market, quotations of
    interest rates for the relevant deposits are not being provided in the
    relevant amounts or for the relevant maturities for 

                                       31
<PAGE>

    purposes of determining the rate of interest for such LIBOR Advances 
    under this Agreement; or 

         (ii)      the rates of interest referred to in the definition of
    "LIBOR Base Rate" in Section 1.01 hereof upon the basis of which the rate
    of interest on any LIBOR Advance for such period is determined, do not
    accurately reflect the cost to the Creditor of making or maintaining such
    LIBOR Advance for such period,

then the Creditor shall give the Company prompt notice thereof (and shall
thereafter give the Company prompt notice of the cessation, if any, of such
condition), and so long as such condition remains in effect, the Creditor shall
be under no obligation to make LIBOR Advances or to convert Prime Advances into
LIBOR Advances pursuant to subsection 2.02(a) hereof and the Company shall, on
the last day(s) of the then current Interest Period(s) for the outstanding LIBOR
Advances either prepay such LIBOR Advances in accordance with Section 2.05
hereof or convert such LIBOR Advances in Prime Advances.

    (c)       Without prejudice to the provisions of Section 11.02 hereof, in
the event of default by the Company in payment of any principal amount of the
Advances or interest thereon when due (whether at the stated maturity, by
acceleration or otherwise), the Company shall pay to the Creditor interest on
such past due and unpaid principal amount and (to the extent permitted by
applicable law) on such defaulted interest from the due date until the date of
payment in full (both before as well as after judgment), at the Post-Default
Rate.  In addition, the Company shall indemnify the Creditor against any loss or
expense which it may sustain or incur as a direct consequence of the default by
the Company in payment of any principal amount of the Advances or interest
thereon.  Each determination of any loss or expense by the Creditor under this
paragraph (c) shall be conclusive in the absence of manifest error.

    (d)       Interest on all Prime Advances shall be computed on the basis of
a year of 365/366 days and actual days elapsed (including the first day but
excluding the last) occurring in the period for which payable and interest on
all LIBOR Advances shall be computed on the basis of 360 days and actual days
elapsed (including the first day but excluding the last) occurring in the period
for which payable.

    (a)       Except as otherwise provided herein, all payments whatsoever by

in Dollars in same-day funds to the order of Motorola, Inc. at Harris Bank,
Chicago, Illinois, USA, ABA# 071-000-288, for the account of Motorola Credit

next succeeding Business Day for purposes of calculating interest thereon.

    (b)       If any payment hereunder or under the Financing Note would
otherwise be due on a day that is not a Business Day, such payment shall be made
on the next succeeding day that is a Business Day and including the additional
days elapsed in the computation of the interest payable on such next succeeding
Business Day.

SECTION 2.08  USE OF PROCEEDS.

    The Company agrees that the proceeds of the Advances will be used by the
Company solely to finance the purchase of equipment and services acquired
pursuant to the iDEN Equipment and Service Agreements (including down payments,
milestone payments and other payments due under the iDEN Equipment and Service
Agreements) to be used in connection with the System excluding import taxes
and/or duties related thereto.  If the Initial Funding Date occurs on or prior

SECTION 2.09  CHANGE IN LAW.

    If any change in applicable law or regulation or in the interpretation
thereof by any Governmental Authority charged with the administration thereof
has made (or has made it apparent that it is) unlawful for any Credit Party to
perform any of its obligations under any of the Credit Documents and such change
could reasonably be expected to have a Material Adverse Effect then (i) the
Creditor shall be discharged from all obligation to make, renew or maintain the
Advances, and (ii) the Company shall on demand pay to the Creditor without
premium or penalty the outstanding principal amount of the Advances together
with accrued interest thereon and all other moneys due to the Creditor
hereunder; PROVIDED, THAT for so long as the Company is diligently pursuing the
contest of the same by appropriate proceedings and such contest could not
reasonably be expected to have a Material Adverse Effect and adequate reserves
have been established in accordance with GAAP, then the Creditor shall not be so
discharged and the Company shall not be required to so pay upon demand.

SECTION 2.10 ILLEGALITY.

    If any change in applicable law or regulation or in the interpretation
thereof by any Governmental Authority charged with the administration thereof
has made (or has made it apparent that it is) unlawful for the Creditor to
perform its obligations hereunder, then (i) the Creditor shall be discharged

penalty the outstanding principal amount of the Advances together with 
accrued interest thereon and all other moneys due to the Creditor hereunder.  
Notwithstanding the foregoing, the Creditor will use reasonable endeavors to 
assist in any restructuring necessitated by this Section 2.10; PROVIDED, 
HOWEVER, that the Creditor shall be under no obligation to take any action 
the effect or likely effect of which, in the opinion of the Creditor could 
reasonably be expected to have an adverse effect upon the Creditor; PROVIDED, 
FURTHER, that the Company shall reimburse the Creditor on demand for all 
expenses (including attorneys' fees) incurred by the Creditor in assisting in 
any such restructuring.

SECTION 3.01  TAXES, DUTIES, FEES AND CHARGES.

    (a)       All payments due to the Creditor under any of the Credit
Documents, whether of principal, interest, penalties, fees or otherwise,
including payments made under this subsection 3.01(a), shall be made without
set-off, withholding or counterclaim, and free and clear and without any
deduction or withholding on account of any Taxes, all of which shall be for the
account of the Company and paid by it directly to the relevant taxing or other
authority when due.  If the Company shall be required by law to make any
deduction or withholding in respect of Taxes from any payment hereunder,
including payments made under this subsection 3.01(a), the sum payable shall be
increased to such sum as will result in the receipt by the Creditor after such
deduction or withholding, of the amount that would have been received if such
deduction or withholding had not been required.

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

    (c)       The Company shall deliver to the Creditor within thirty days
after the payment thereof copies of the receipts evidencing payment of any
withholding taxes to any Governmental Authority.

SECTION 3.02  CHANGE IN CIRCUMSTANCES.

    (a)       In the event that there shall hereafter occur any change in any
Governmental Rule which increases or will increase (i) the cost of maintaining
any reserves or special deposits against the Commitment or the LIBOR Advances or
(ii) any other cost of complying with any law, regulation or condition with
respect to the Commitment or the LIBOR Advances, and the result of any of the
foregoing is or will be to increase the cost to the Creditor of making or
maintaining the Commitment or the LIBOR Advances or to reduce the amount of any
payment (whether of principal, interest or otherwise) receivable by the Creditor
hereunder, then upon receipt of a request from the Creditor the Company shall
pay or reimburse to the Creditor such 

                                       34
<PAGE>

amount as will compensate the Creditor for such additional cost or reduction 
of payment; PROVIDED that the Company shall only be liable for such costs 
applicable to LIBOR Advances then outstanding. Amounts payable hereunder 
shall be due seven (7) days after invoice therefor.

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

    (c)       The Creditor will promptly (but in no event later than twenty
(20) days after actual knowledge of the occurrence of the event described in
subsection 3.02(a) hereof) inform the Company by facsimile of its intention to
claim indemnification under this Section 3.02.  The facsimile statement of the
Creditor as to the amount sufficient to indemnify the Creditor against any
increased cost, reduction or payment incurred, suffered or made by the Creditor,
supported by the computations made by the Creditor in arriving at such figure,
shall, in the absence of manifest error, be conclusive as to the amount thereof
and binding on Company.

    A claim made under this Section 3.02 may be made before or after the end of
the Interest Period to which such claim relates and before or after any
repayment of all or part of the Advance to which such Interest Period relates;
PROVIDED, THAT the Company shall in no event be liable for any payment under
this Section 3.02 with respect to more than one Interest Period for each claim
made under this Section 3.02.  An increased cost shall be an increased cost for
the purpose of subsection 3.02(a) hereof even if the payment or quantification
of such increased cost is not or cannot be made until after the expiry of any
Interest Period to which it relates.

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

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

Approvals identified on Part I of each of Sections A and B of Schedule

expected to rescind, terminate, modify or suspend any Governmental Approval 
listed in Part II of Sections A and B of Schedule 7.03(a) hereto, and no such 
disclosed matter could reasonably be expected to have a Material Adverse 
Effect.  None of Nextel International, the Company and AirLink, respectively,

authorization of, or declaration or filing with, any other Person is required 
in connection with (i) the construction, ownership, operation or maintenance

Business currently engaged in, or (iii) as to such Credit Party and, to the 
Company's knowledge after due inquiry, as to Persons affiliated with any 
Credit Party, with the execution, delivery, performance, validity or

    (b)  Schedule 7.03(b) sets forth all Licenses that are necessary for (i) 
the ownership, operation or maintenance of the System in the Major Market

Material Adverse Effect on the Company and the Foreign Affiliates taken as a 
whole to achieve the Approved Business Plan in the Major Market Areas) as is 
contemplated by the Approved Business Plan, and (ii) the Telecommunications 
Business currently engaged in.  Except to the extent expressly set forth in

or in respect of any of the provisions of any License except for defaults 
resulting from the failure to meet certain milestones set forth in such 
Licenses which failure could not reasonably be expected to have a Material 
Adverse Effect.  No authorization, approval, application, filing, 
registration, consent or other action of any local, state or federal 
authority is required to enable the Company or any Foreign Affiliate to 
operate under its respective License (except such Licenses which are 
ministerial in nature or which the failure to obtain such License could not 
reasonably be expected to have a Material Adverse Effect on the Company and 
the Foreign Affiliates taken as a whole to achieve the Approved Business Plan 
in the Major Market Areas) other than those filings made and referred to on 
Schedule 7.03(b) hereto.  There is no proceeding pending, or to the knowledge 
of the Company after due inquiry, threatened, which could rescind, terminate, 
modify or suspend any such approval, filing, registration or consent, and no 
such disclosed proceeding could reasonably be expected to have a Material 
Adverse Effect.  None of Nextel International, the Company and AirLink, 
respectively, have any knowledge that theinformation set forth in each 
application submitted by the Company and any Foreign Affiliate in connection 
with each such approval, filing, registration or consent is not accurate or 
complete in any material respect.

Party enforceable in accordance with its terms except as (w) the 
enforceability of a pledge of more than 49% of the ownership interest of an

enforceability thereof may be limited by bankruptcy, insolvency or similar 
laws relating or affecting creditors' rights generally, (y) the availability 
of equitable remedies, and (z) rights to indemnification and contribution as

the Security Documents or the Liens created thereby, except for: (i) possible 
delay, (ii) situations that may arise under Chapter 11 of the Bankruptcy 
Code, and (iii) equitable orders of the Bankruptcy Court.  The execution, 
delivery and performance of the terms of each of the Operative Documents by 
each Credit Party and the payment by such Credit Party of all amounts due on 
the dates and in the currency provided for therein (i) will not, except as is 
set forth on Schedule 7.04 hereto, violate or contravene any Governmental 
Rule or other provision of law or other governmental directive, whether or 
not having the force of law, which is applicable to such Credit Party, which 
set forth violation or contravention thereof individually and in the 
aggregate could not reasonably be expected to have a Material Adverse Effect; 
(ii) will not, except as is set forth on Schedule 7.04 hereto, contravene any

or assets is bound other than the Credit Documents; (v) will not constitute a 
default or an event that, with the giving of notice or the passing of time, 
or both, would constitute a default under any such agreement or instrument;

been obtained on or prior to the Initial Funding Date and are and will remain 
in full force and effect and no further action is needed with respect 
thereto) do not require any governmental consent, registration or approval.

matter related to an "employee benefit plan", within the meaning of Section 
3(3) of ERISA, or a "plan", within the meaning of Section 4975(e)(1) of the

SECTION 7.08  COMPLIANCE WITH LAWS.

    (a)  Each Credit Party complies and has complied in all material respects 
with all applicable Governmental Rules, and any such non-compliance cannot, 
individually or in the aggregate, be reasonably expected to have a Material

in the preceding sentence relate to any Governmental Rule related to an 
"employee benefit plan", within the meaning of Section 3(3) of ERISA, or a 
"plan", within the meaning of Section 4975(e)(1) of the Code, such 
representations and warranties are made assuming the truth of the 
representation, warranty and covenant contained in the second sentence of 
subsection 2.01(a).  Except as previously disclosed to the Creditor in 
writing, no such Credit Party has received any communication of which the

becoming aware thereof, from a Governmental Authority that alleges that such 
Credit Party is not in full compliance in all material respects with all 
applicable Governmental Rules, and to the Company's knowledge, after due 
inquiry, there are no circumstances that may prevent or interfere with such 
full compliance in all material respects in the future.

    (b)  Each Credit Party is in compliance in all material respects with all 
applicable laws relating to the employment of labor, wages, hours and 
conditions of work, collective bargaining, withholding tax and the payment of 
social security contributions and other labor-related taxes, and any

expected to have a Material Adverse Effect.  Such Credit Party is not liable 
for any arrears in wages, compensation, benefits, premiums, taxes or 
penalties for failure to comply with any of the foregoing laws except to the 
extent that the same are being contested in good faith and by proper 
proceedings and as to which either (x) adequate reserves have been 
established in accordance with GAAP on the books of such Credit Party or (y) 
non-payment of which could not have a Material Adverse Effect under such 
circumstances and could not result in an aggregate liability in excess of

    (a)       Each of Nextel International, the Company and the Foreign

conducted in full compliance under the United States Foreign Corrupt 
Practices Act and any other applicable law dealing with improper or illegal

days after such request, each of the Company and Nextel International shall 
provide the Creditor with certification to the effect that neither it nor any 
of its Subsidiaries has made any payments, directly or indirectly, in

covenants contained in this Section 8.11 shall not be deemed to have been 
violated to the extent any failure to comply with any Governmental Rule or 
any other requirement of this Section 8.11 is attributable to a breach of the 
representation, warranty or covenant contained in the second sentence of 
Section 2.01(a) hereto.  Each Credit Party warrants and represents that since 
the merger with Wireless it has not taken any action, or failed to take any 
action, with respect to the System or the Telecommunications Business if that 
act or failure to act would have violated this Section 8.11.  Nextel 
International and the Company warrant and represent that prior to the merger 
with Wireless, Nextel International and the Company conducted reasonable due 
diligence of Wireless and its subsidiaries and in connection therewith 
nothing came to their attention or led them to believe that the activities of 
Wireless or any officers, directors or agents thereof could be construed as 
violations of the United States Foreign Corrupt Practices Act of Wireless and 
its subsidiaries if they had been whollyowned subsidiaries of Nextel 
International at the time of such activities.  To the extent the warranties 
and representations contained in this Section 8.11(a) relate to any 
Governmental Rule, including, but not limited to, the United States Foreign 
Corrupt Practices Act, related to an "employee benefit plan", within the 
meaning of Section 3(3) of ERISA, or a "plan", within the meaning of Section 
4975(e)(1) of the Code, such warranties and representations are made assuming 
the truth of the representation, warranty and covenant contained in the 
second sentence of Section 2.01(a).

which is subject to any mortgage securing directly or indirectly all or any 
part of the Advances, and the cost of delineation, removal, treatment and 
disposal of any such Materials of Environmental Concern.  If the Company or 
Nextel International fails to do any of the foregoing, then (i) after the 
occurrence of an Event of Default related thereto which is continuing under 
this Agreement or (ii) in the event the Creditor sustains any liability, 
loss, cost, damage or expense (including reasonable attorneys' fees and 
expenses) arising out of the presence of Materials of Environmental Concern

Telecommunications Business or the Collateral, the Creditor may cause the 
System, the assets of the Telecommunications Business or the Collateral to be 
freed (by removal or otherwise) from such Materials of Environmental Concern,

and laboratories' fees and expenses) shall be added to the Obligations of the 
Company pursuant to this Agreement and secured by the Security Documents.  
Nextel International, the Company and each Foreign Affiliate will give to the 
Creditor and its agents and employees reasonable access to the System, the 
assets of the Telecommunications Business and the Collateral to effect the 
foregoing, including, without limitation, following such failure the periodic

Company and AirLink further agree to observe applicable laws relating to a 
minimum age for employment of children, acceptable conditions of work with 
respect to minimum wages, hours of work and occupational health and safety, 
and not to use forced labor. Additionally, the Company and AirLink agree to 
take action to assure that employees shall be permitted to remove themselves 
from dangerous work situations without jeopardy to their continued

presentment, demand, protest or further notice of any kind, all of which are

contained in this Agreement and the other Credit Documents, all of the rights
and remedies of a secured party under the laws of the United States and the laws
of Brazil or other applicable laws, all of which rights and remedies shall be

    (b)       In addition to such remedies as are provided for in this

right to apply or require the Company to apply for any necessary orders or
licenses in connection with the operation or abandonment of the System, the
Telecommunications Business or any part thereof; and (ii) to the extent
permitted by law, a right to have a receiver appointed by a court of competent
jurisdiction in order to manage, protect and preserve the System, the
Telecommunications Business and all other equipment, property and other
collateral and to continue the operation of the business of the Company, and to
collect the revenues and profits thereof and apply the same to the payment of

    (c)  The Company agrees, in case an Event of Default shall be existing 
and upon the Creditor's request, to assemble, at its expense, all equipment 
constituting a part of the Collateral at a convenient place acceptable to the 
Creditor and to pay all the Creditor's costs of collection of all amounts 
due, and enforcement of all rights hereunder, including reasonable attorney's 
fees and legal expenses, and expenses of any repairs to any realty or other 
property to which any of such equipment may be affixed or be part.  Upon an 
Event of Default, the Creditor may, to the fullest extent permitted by 
applicable law, without notice, advertisement, hearing or process of law of 
any kind (i) to the extent permitted by law, enter upon any premises where 
any of the equipment constituting part of the Collateral may be located and 
take possession of and remove such equipment, (ii) sell any or all of such 
equipment, free of all rights and claims of the Company therein and thereto, 
at any public or private sale, and (iii) to the extent permitted by law, bid 
for and purchase any or all of such equipment at any such sale.

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

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

    (f)  In connection with the foregoing remedies, the Company and Nextel 
International shall take such further actions and execute all such 
instruments as the Creditor deems necessary.  The Company agrees that the 
Creditor may enforce any obligation of the Company as set forth in this 
Agreement by an action for specific performance.

                                      90

<PAGE>

    (g)  The Creditor may (but shall not be obligated to) make advances to 
preserve, protect or obtain any of the Collateral, including advances to pay 
taxes, insurance and the like, and all such advances shall become part of the 
obligations owing to the Creditor hereunder and shall be repayable to the 
Creditor with interest thereon from the date of such advance until paid at 
the rate per annum of 2% above the average interest rate applicable to the 
Financing Note on the date of such advance.

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

    (i)  All moneys received by the Creditor pursuant to any right given or 
action taken under Section 11 of this Agreement shall be applied as follows:

         FIRST - To the reimbursement to the Creditor of all reasonable 
expenses and costs of litigation and of any proceedings resulting in the 
collection of such moneys, including, without limitation, attorney's fees, 
receivership, collection, maintenance, improvements and other acts of 
administration and sale of properties;

         SECOND - To the payment of the unpaid principal of and interest on 
any Advance which shall have become due and payable and other fees, costs and 
expenses which the Company is required to pay from time to time to the 
Creditor under or pursuant to this Agreement or any other Credit Document, as 
well as all other obligations, covenants, undertakings and liabilities of the 
Company to the Creditor arising out of or in connection with this Agreement 
or any other Credit Document, which shall have become due and payable in such 
order as the Creditor may decide; and 

         THIRD - The balance, if any, shall be delivered and paid to the 
Company.

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

                                      91

<PAGE>

    (k)  The Creditor may exercise any and all of its remedies under the 
Security Documents, the Stockholder Guaranties and the Foreign Affiliate 
Guaranties contemporaneously or separately from the exercise of any other 
remedies hereunder or with respect to any Collateral.

11.03 CUMULATIVE RIGHTS.

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

11.04 WAIVER OF DEMAND.

    DEMAND, PRESENTMENT, PROTEST AND NOTICE OF DEMAND, PRESENTMENT, PROTEST 
AND NONPAYMENT ARE HEREBY WAIVED TO THE EXTENT PERMITTED BY LAW BY THE 
COMPANY.  THE COMPANY ALSO WAIVES THE BENEFIT OF ALL VALUATION, APPRAISAL AND 
EXEMPTION LAWS TO THE EXTENT PERMITTED BY LAW.

11.05 WAIVER OF NOTICE.

    IN THE EVENT OF AN EVENT OF DEFAULT, THE COMPANY HEREBY WAIVES TO THE 
EXTENT PERMITTED BY LAW ALL RIGHTS TO NOTICE AND HEARING OF ANY KIND PRIOR TO 
THE EXERCISE BY THE CREDITOR OF ITS RIGHTS TO REPOSSESS ANY COLLATERAL 
WITHOUT JUDICIAL PROCESS OR TO REPLEVY, ATTACH OR LEVY UPON ANY COLLATERAL 
WITHOUT PRIOR NOTICE OR HEARING.  THE COMPANY ACKNOWLEDGES THAT IT HAS BEEN 
ADVISED BY COUNSEL OF ITS CHOICE WITH RESPECT TO THIS TRANSACTION AND THIS 
AGREEMENT.

                                12.  MISCELLANEOUS
